Default Rate. To the extent permitted by Law, beginning on the date that they become past due, all past-due payments of the Obligation accrue interest at the Default Rate until paid, regardless of whether payment is made before or after entry of a judgment.

4.7

Interest Calculations. Interest will be calculated on the basis of actual number of days elapsed (including the first day but excluding the last day), but computed as if each calendar year consisted of 360 days (unless such computation would result in an interest rate in excess of the Maximum Rate, in which event the computation is made on the basis of a year of 365 or 366 days, as the case may be). All interest rate determinations and calculations by Lender are conclusive and binding, absent manifest error.

4.8

Maximum Rate. Regardless of any provision contained in any Loan Document, it is the intention of Borrower and Lender that Lender may not contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the Obligation any amount in excess of the Maximum Rate or the Maximum Amount or receive any unearned interest, in violation of any applicable Law and if Lender does so, any excess will be deemed to be and treated as a partial prepayment or repayment of the outstanding principal portion of the Obligation and any remaining excess will be refunded to Borrower. In determining whether interest paid or payable exceeds the Maximum Rate, Borrower and Lender shall, to the maximum extent permitted under applicable Law, (a) treat all Borrowings as a single extension of credit (Lender and Borrower agree that such is the case and that provision in this Agreement for multiple Borrowings is for convenience only), (b) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments or repayments and their effects, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Obligation. However, if the Obligation is paid in full before the end of its full contemplated term, and if the interest received for its actual period of existence exceeds the Maximum Amount, Lender shall refund any excess (and Lender may not, to the extent permitted by Law, be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Maximum Amount). If the

Laws of the State of Texas are applicable for purposes of determining the "Maximum Rate" or the "Maximum Amount," then those terms mean the "indicated rate ceiling" from time to time in effect under Chapter 303 of the Texas Finance Code, as amended. Borrower agrees that Chapter 346 of the Texas Finance Code, as amended (which regulates certain revolving credit loan accounts and revolving tri-party accounts), does not govern or apply to the Obligation.

4.9

Offset. If a Default exists, Lender is entitled, but is not obligated, to exercise the Rights of offset and banker's Lien against each and every account and other property, or any interest therein, that Borrower may now or in the future have with Lender, or which is now or in the future in the possession of Lender, to the extent of the full amount of the Obligation.

SECTION 5.

FEES. Borrower and Lender agree that any fees charged by Lender under this Agreement, at any time, (a) do not constitute compensation for the use, detention, or forbearance of money, (b) are in addition to, and not in lieu of, interest and expenses otherwise described in this Agreement, (c) are payable in accordance with Section 4.1, (d) are non-refundable, (e) accrue interest, if not paid when due, at the Default Rate, (f) are calculated on the basis of actual number of days elapsed (including the first day but excluding the last day), but computed as if each calendar year consisted of 360 days (unless computation would result in an interest rate in excess of the Maximum Rate, in which event the computation is made on the basis of a year of 365 or 366 days, as the case may be), and (g) are in all events subject to the provisions of Section 4.8.

SECTION 6.

CONDITIONS PRECEDENT. Lender will not be obligated to fund the initial Borrowing unless it has received (i) the Commitment Fee, (ii) all of the items described on Schedule 6, each in Proper Form, (iii) an appraisal, satisfactory to Lender in its sole discretion, of the collateral and properties subject to the Liens under the Security Documents, (iv) a Phase I Environmental Site Assessment, satisfactory to Lender in its sole discretion, on the properties subjected to the Liens under the Deed of Trust, (v) copies of all surveys, or other legal descriptions, acceptable to Lender, of the properties covered by the Deed of Trust and (vi) a title policy with respect to the properties covered by the Deed of Trust. In addition, Lender will not be obligated to fund any Borrowing unless on the applicable Borrowing Date (and after giving effect to the requested Borrowing): (a) Lender has timely received a Notice of Borrowing; (b) all of the representations and warranties of Borrower in the Loan Documents are true and correct in all material respects (except to the extent that (i) the representations and warranties speak to a specific date or (ii) the facts on which the representations and warranties are based have been changed by transactions contemplated or permitted by this Agreement); (c) no Material Adverse Event has occurred and is continuing; and (d) no Default or Potential Default exists. Each Notice of Borrowing delivered to Lender constitutes the representation and warranty by Borrower to Lender that the statements in clauses (b), (c), and (d) above are true and correct in all respects. Each condition precedent in this Agreement (including, without limitation, matters listed on Schedule 6) is material to the transactions contemplated by this Agreement, and time is of the essence with respect to each condition precedent. Lender may fund any Borrowing without all conditions being satisfied, but, to the extent permitted by Law, that funding shall not be deemed a waiver of the requirement that each condition precedent be satisfied as a prerequisite for any subsequent funding unless Lender specifically waives each item in writing.

SECTION 7.

SECURITY.

7.1

Collateral. The complete payment and performance of the Obligation shall be secured by all of the items and types of property described as collateral in the Security Agreement and other Security Documents executed by Borrower in favor of Lender, including those Security Documents executed heretofore, on the date hereof and hereinafter, specifically including, without limitation, those Security Documents described on Schedule 7.1 attached hereto (collectively, the "Collateral").

WHEREAS, each Guarantor will directly and indirectly benefit from the advances under the Term Loan, as defined in the Credit Agreement, as evidenced by the Notes.

WHEREAS, each Guarantor is providing this Guaranty pursuant to Section 7 of the Credit Agreement.

NOW, THEREFORE, for and in consideration of the premises and the extension of credit by Bank to Borrower pursuant to the Credit Agreement, and for TEN AND NO/100 DOLLARS ($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and to induce Bank to execute the Credit Agreement, Bank and Guarantor hereby agree as follows:

ARTICLE 1 - DEFINITIONS; INTERPRETATION

1.1

Definitions. Except as otherwise expressly provided herein, capitalized terms used in this Guaranty shall have the meanings given in the Credit Agreement.

1.2

Rules of Interpretation. Except as otherwise expressly provided herein, the rules of interpretation set forth in the Credit Agreement shall apply to this Guaranty.

ARTICLE 2 - GUARANTY COVENANT

2.1

Guaranty. Each Guarantor hereby irrevocably, absolutely and unconditionally guarantees to the Bank, as principal and not merely as surety, the payment in full when due, and in the currency in which the same falls due, of amounts payable by the Borrower under the Credit Agreement (whether at their scheduled due dates, upon early termination or otherwise) (the "Guaranteed Obligations").

2.2

Term and Reinstatement. (a) This Guaranty shall remain in force and effect from the date first above written unless and until all Guaranteed Obligations have been paid, and (b) this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by the Bank upon the bankruptcy, insolvency, dissolution, reorganization or liquidation of the Borrower or either Guarantor or otherwise, all as though such payment had not been made.

2.3

Reporting. Deliver to Bank, promptly after preparation, and no later than 120 days after the last day of each fiscal year of each Guarantor, (i) audited financial statements (including an income statement, balance sheet and statement of cash flows) showing the consolidated financial condition and results of operations of each Guarantor as of, and for the year ended on, that last day and (ii) the unqualified opinion of a firm of independent certified public accountants reasonably acceptable to Lender, based on an audit using generally accepted auditing standards, that the financial statements were prepared in accordance with GAAP and present fairly, in all material respects, the financial condition and results of operations of each Guarantor and its Subsidiaries.

ARTICLE 3 - MISCELLANEOUS

3.1

This Guaranty is intended to be solely for the benefit of the Bank and its successors and permitted assigns and is not intended to and shall not confer any rights or benefits on any other third party.

3.2

All notices, requests, demands and other communications which are required or may be made or given under this Guaranty shall be in writing and shall be sufficient in all respects if delivered to the relevant address indicated on the signature page of this Guaranty (including delivery by registered or certified United States mail, facsimile, telegram or hand).

3.3

If the Guaranteed Obligations is not paid by Guarantors when due, as required herein, and this Guaranty is placed in the hands of an attorney for collection, or if this Guaranty is enforced by suit or through the Bankruptcy Court or through any judicial proceedings, Guarantors shall pay to Bank an amount equal to its reasonable attorneys' fees and collection costs incurred by Bank in the collection of the Guaranteed Obligations.

3.4

This is an absolute, complete and continuing Guaranty, and no notice of the Guaranteed Obligations or any extension of credit already or hereafter contracted by or extended to Borrower need be given to Guarantors, nor shall anything herein contained be a limitation upon the amount of credit which may be extended to Borrower, the numbers of transactions with

Borrower, repayments by Borrower to Bank, or the allocation by Bank of repayment by Borrower, it being the understanding of each Guarantor that each Guarantor's liability shall continue hereunder so long as any of the Guaranteed Obligations remains unpaid. Borrower and Bank may rearrange, increase, decrease, extend and/or renew the Guaranteed Obligations without notice to Guarantors and in such event each Guarantor will remain fully bound hereunder on the Guaranteed Obligations. The obligations of Guarantors hereunder shall not be released, impaired or diminished by any amendment, modification or alteration of the Credit Agreement or the Notes. Guarantors expressly waive all notices of any kind, presentment for payment, demand for payment, protest, notice of protest, notice of intent to accelerate, notice of acceleration, dishonor, diligence, notice of any amendment of the Credit Agreement, notice of any adverse change in the financial condition of Borrower, notice of any adjustment, indulgence, forbearance or compromise that might be granted or given by Bank to Borrower, and also notice of acceptance of this Guaranty, acceptance on the part of Bank being conclusively presumed by its request for this Guaranty and delivery of the same to it. The liability and obligations of Guarantors hereunder shall not be affected or impaired by any action or inaction by Bank in regard to any matter waived or notice of which is waived by Guarantors in this paragraph or in any other paragraph of this Guaranty.

3.5

Guarantors authorize Bank, without notice or demand and without affecting Guarantors' liability hereunder, (a) to take and hold security for the payment of this Guaranty and/or the Guaranteed Obligations, and to exchange, enforce, waive and/or release any such security; (b) to apply such security and direct the order or manner of sale thereof as Bank in its discretion may determine; (c) to obtain a guaranty of the Guaranteed Obligations from any one or more other persons, corporations or entities whomsoever and to enforce, waive, rearrange, modify, limit or release at any time or times such other persons, corporations or entities from their obligations under such guaranties; (d) to waive or delay the exercise of any of its rights or remedies against the Borrower or any other person or entity; (e) to renew, extend, or modify the terms of any of the Guaranteed Obligations or any instrument or agreement evidencing the same; and (f) to fully or partially release at any time any Guarantor which executes this Guaranty whether with or without consideration.

3.6

Each Guarantor waives any right to require Bank to (a) proceed against, or make any effort at the collection of the Guaranteed Obligations from Borrower or any other guarantor (including the other Guarantor) or party liable for the Guaranteed Obligations; (b) proceed against or exhaust any collateral held by Bank; or (c) pursue any other remedy in Bank's power whatsoever. Each Guarantor further waives any and all rights and remedies which Guarantor may have or be able to assert by reason of the provisions of Chapter 34 of the Texas Business and Commerce Code. Each Guarantor waives any defense arising by reason of any disability, lack of corporate authority or power, or other defense of Borrower or any other guarantor of the Guaranteed Obligations, and each Guarantor shall remain liable under this Guaranty regardless of whether Borrower or any other guarantor (including the other Guarantor) be found not liable on the Guaranteed Obligations for any reason including, without limitation, insanity, minority, disability, bankruptcy, insolvency, death or corporate dissolution, even though rendering the Guaranteed Obligations void or unenforceable or uncollectible as against Borrower or any other guarantor (including the other Guarantor). This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by Bank upon the insolvency, bankruptcy or

reorganization of Borrower or otherwise, all as though such payment had not been made and will, thereupon, guarantee payment of such amount as to which refund or restitution has been made, together with interest accruing thereon subsequent to the date of refund or restitution at the applicable rate under the Notes and collection costs and fees (including, without limitation, attorneys' fees) applicable thereto.

3.7

The liability and obligations of Guarantors hereunder shall not be affected or impaired by (a) the failure of Bank or any other party to exercise diligence or reasonable care in the preservation, protection or other handling or treatment of all or any part of the collateral securing payment of all or any part of the Guaranteed Obligations, (b) the failure of any security interest or lien intended to be granted or created to secure the Guaranteed Obligations to be properly perfected or created or the unenforceability of any security interest or lien for any other reason, or (c) the subordination of any such security interest or lien to any other security interest or lien.

3.8

Bank may pursue any remedy without altering the obligations of Guarantors hereunder and without liability to Guarantors, even though Bank's pursuit of such remedy may result in Guarantors' loss of rights of subrogation or to proceed against others for reimbursement or contribution or any other right. In no event shall any payment by either Guarantor entitle it, by subrogation or otherwise, to any rights against Borrower or any right to participate in any security now or hereafter held by Bank prior to payment in full of all of the Guaranteed Obligations. Notwithstanding anything contained in this Guaranty to the contrary, Guarantors agree that if, but for the application of this Section 3.8, the Guaranteed Obligations would constitute a preferential transfer under 11 U.S.C. 547, a fraudulent conveyance under 11 U.S.C. 548 (or any successor section of that Code) or a fraudulent conveyance or transfer under any state fraudulent conveyance or fraudulent transfer law or similar law in effect from time to time (each a "Fraudulent Conveyance"), then the Guaranteed Obligations will be enforceable to the maximum extent possible without causing the Guaranteed Obligations to be a Fraudulent Conveyance, and shall be deemed to have been automatically amended to carry out the intent of this Section 3.8. Guarantors have received reasonably equivalent value as consideration for executing and delivery this Guaranty.

3.9

Should the status of Borrower change in any way, including, without limitation, as a result of any dissolution of Borrower, any sale, lease or transfer of any or all of the assets of Borrower, any changes in the owners of Borrower, or any reorganization of Borrower, this Guaranty shall continue, and shall cover the Guaranteed Obligations under the new status.

3.10

The liability of Guarantors for the payment of the Guaranteed Obligations shall be primary and not secondary.

3.11

Each Guarantor is familiar with and has independently reviewed the books and records regarding the financial condition of Borrower and is familiar with the value of any and all collateral intended to be granted as security for the payment of the Guaranteed Obligations; neither Guarantor is, however, relying on such financial condition or such collateral as an inducement to enter into this Guaranty.

3.12

If Borrower shall at any time or times be or become obligated to Bank for payment of any indebtedness other than the Guaranteed Obligations, Bank (without in anywise impairing its rights hereunder or diminishing Guarantors' liability) shall be at liberty at any time or times to apply to such other indebtedness any amounts paid to or received by or coming into the hands of Bank from or attributable to Borrower or any other person or party liable for any of such other indebtedness or from or attributable to or representing proceeds of any property or security held by Bank securing payment of such other indebtedness or any credits, deposits or offsets due Borrower or other party liable on any of such other indebtedness (whether or not the Guaranteed Obligations or such other indebtedness are then due), it being intended to give Bank the right to apply all payments, credits and offsets and amounts becoming available for application on or credit against the indebtedness of Borrower to Bank (now or hereafter existing) first toward payment and satisfaction of the Borrower's indebtedness not hereby guaranteed, before making application thereof on or against the Guaranteed Obligations.

3.13

Guarantors acknowledge that Guarantors are not relying on any representations (oral or otherwise) of Bank, or any other party, other than as expressly described in this Guaranty.

3.14

This Guaranty was reviewed by each Guarantor, and each Guarantor acknowledges and agrees that such Guarantor (a) understands fully all of the terms of this Guaranty and the consequences and implications of such Guarantor's execution of this Guaranty, and (b) has been afforded an opportunity to have this Guaranty reviewed by, and to discuss the terms, consequences and implications of this Guaranty with an attorney or other such persons as such Guarantor may have desired.

3.15

This Guaranty is and shall be in every particular available to the successors and assigns of Bank and is and shall always be fully binding upon the heirs, executors, administrators, successors and assigns of each Guarantor. This Guaranty is intended for and shall inure to the benefit of Bank and each and every other person who shall from time to time be or become the owner or holder of any of the Guaranteed Obligations, and each and every reference herein to "Bank" shall also include and refer to each and every successor or assignee of Bank at any time holding or owning any part of or interest in any part of the Guaranteed Obligations. This Guaranty shall be transferable and negotiable, with the same force and effect and to the same extent that the Guaranteed Obligations is transferable, it being understood and stipulated that upon the assignment or transfer by Bank of any of the Guaranteed Obligations the legal or beneficial owner of the Guaranteed Obligations (or part thereof or interest therein thus transferred or assigned by Bank) shall also, unless provided otherwise by Bank in its assignment, have and may exercise all of the rights granted to Bank under this Guaranty to the extent of the part of or interest in the Guaranteed Obligations thus assigned or transferred to such person or entity. Guarantors expressly waive notice of transfer or assignment of the Guaranteed Obligations, or any part thereof, or of the rights of Bank hereunder.

It is the intention of the parties hereto to comply strictly with all applicable usury laws; accordingly, it is agreed that notwithstanding any provisions to the contrary in this Guaranty, or in any documents securing payment hereof or otherwise relating hereto, in no event shall this Guaranty or such documents require the payment or permit the collection of an aggregate amount of interest in excess of the maximum amount permitted by such laws, including the laws of the State of Texas and the laws of the United States of America. If any such excess of interest is contracted for, charged or received under this Guaranty or under the terms of any documents securing payment hereof or otherwise relating hereto, or if under any circumstances, the amount of interest (including all amounts payable hereunder which are not denominated as interest but which constitute interest under the applicable laws) contracted for, charged or received under this Guaranty shall exceed the maximum amount of interest permitted by the applicable usury laws, then in any such event (a) the provisions of this paragraph shall govern and control, (b) Guarantors shall not be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted by the applicable usury laws, (c) any such excess interest which may have been collected shall be either applied as a credit against the then unpaid Guaranteed Obligations or, if the Guaranteed Obligations shall have been paid in full, refunded to Guarantors, and (d) the effective rate of interest shall be automatically reduced to the maximum lawful contract rate allowed under the applicable usury laws as now or hereafter construed by the courts having jurisdiction thereof. It is further agreed that without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under this Guaranty or under such other documents which are made for the purpose of determining whether such rate exceeds the maximum lawful contract rate, shall be made, to the extent permitted by applicable usury laws, by amortizing, prorating, allocating and spreading in equal parts during the full period during which this Guaranty is to be in effect, all interest at any time contracted for, charged or received from Guarantor or otherwise by the holder or holders hereof in connection with this Guaranty.

3.18

In case any of the provisions of this Guaranty shall for any reason be held to be invalid, illegal, or unenforceable, such invalidity, illegality, or unenforceability shall not affect any other provisions hereof, and this Guaranty shall be construed as if such invalid, illegal, or unenforceable provision had never been contained herein.

3.19

In all instances herein, the singular shall be construed to include the plural and the masculine to include the feminine.

3.20

This Guaranty may be executed in multiple counterparts each of which shall constitute an original, but all of which when taken together shall constitute one and the same Guaranty.

3.21

THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA. All actions or proceedings with respect to the Guaranteed Obligations or this Guaranty may be instituted in the Courts of the State of Texas located in ▇▇▇▇▇▇ County, Texas or the United States District Court for the Southern District of Texas, and by execution and delivery of this Guaranty, Guarantors and Bank each irrevocably and

unconditionally submit to the jurisdiction (both subject matter and personal) of each such Court, and irrevocably and unconditionally waive (a) any objection such party may now or hereafter have to the laying of venue in any such Courts, (b) any claim that any action or proceeding brought in any of such Courts has been brought in an inconvenient forum, and (c) any right to bring any action or proceeding with respect to the Guaranteed Obligations or this Guaranty in any forum other than the courts named above in this Section.

3.22

Each Guarantor represents and warrants to Bank that this Guaranty is a valid, binding and enforceable obligation of each Guarantor and does not violate any provisions of any law, rule, regulation, contract or agreement enforceable against such Guarantor.

3.23

This Guaranty is solely and exclusively between Guarantors and the Bank, and any obligations created herein shall be the sole obligations of the parties hereto. No party shall have recourse to any parent, subsidiary, partner, joint venturer, affiliate, director or officer of the other party for performance of said obligations unless the obligations are assumed in writing by the Person against whom recourse is sought.

3.24

Each Guarantor agrees that it may not merge or consolidate with any other Person (as defined in the Credit Agreement) other than mergers between Borrower and Guarantors, so long as (i) Borrower remains the surviving entity after such merger or mergers and (ii) Guarantors keep Bank fully apprised of any such merger or mergers.

3.25

Each Guarantor hereby agrees that a counterpart of this Guaranty bearing the signature of such Guarantor may be effectively delivered to the Bank by the delivery of an electronic facsimile sent via telecopier; and that such Guarantor shall be bound by his facsimile signature thereon.

Security Interest. Subject to the terms and conditions of this Agreement, and to secure the prompt, unconditional and complete payment and performance of the Obligation when due, Debtor grants to Secured Party a security interest in all of Debtor's right, title, and interest in the Collateral and Debtor transfers, pledges, and assigns as security to Secured Party all of Debtor's right, title, and interest in the Collateral.

No Assumption or Modification. The Security Interest is given to secure the prompt, unconditional and complete payment and performance of the Obligation when due, and is given as security only. Secured Party does not assume and shall not be liable for any of Debtor's liabilities, duties, or obligations under or in connection with the Collateral. Secured Party's acceptance of this Agreement, or its taking any action in carrying out this Agreement, does not constitute Secured Party's approval of the Collateral or Secured Party's assumption of any obligation under or in connection with the Collateral. This Agreement does not affect or modify Debtor's obligations with respect to the Collateral.

Collateral. As used in this Agreement, the term "Collateral" means the following items and types of property (as such terms are defined in this Agreement), wherever located, whether now owned or hereafter acquired by Debtor:

(e)

Personalty

The description of Collateral contained in this Section 5 includes after acquired Collateral and proceeds of the Collateral.

Fraudulent Conveyance. Notwithstanding anything contained in this Agreement to the contrary, Debtor agrees that if, but for the application of this Section 6, the Obligation or any Security Interest would constitute a preferential transfer under 11 U.S.C. 547, a fraudulent conveyance under 11 U.S.C. 548 (or any successor section of that Code) or a fraudulent conveyance or transfer under any state fraudulent conveyance or fraudulent transfer law or similar Law in effect from time to time (each a "Fraudulent Conveyance"), then the Obligation and each affected Security Interest will be enforceable to the maximum extent possible without causing the Obligation or any Security Interest to be a Fraudulent Conveyance, and shall be deemed to have been automatically amended to carry out the intent of this Section 6.

Representations and Warranties. Debtor represents and warrants to Secured Party that:

(a)

Binding Obligation. This Agreement creates a legal, valid, and binding Lien in and to the Collateral in favor of Secured Party and enforceable against Debtor. The Security Interest created under this Agreement will be duly perfected once the action required for perfection under applicable Law has been taken. Once perfected, the Security Interest will constitute a first and prior lien on the Collateral, subject only to Permitted Liens. The creation of the Security Interest does not require the consent of any third party, except a third party possessing a Permitted Lien.

(b)

Place of Business; Location of Records. Schedule 1 to this Agreement sets out the location of (i) Debtor's places of business and chief executive office and (ii) the location of its books and records concerning any of the Collateral that are Accounts or General Intangibles. The Debtor's Inventory (until sold in the ordinary course of business) is currently and will in the future be located at the location listed on Schedule 1. The failure of the description of locations of Collateral on Schedule 1 to be accurate or complete will not impair the Security Interest in such Collateral.

(c)

No Prior Lien. Except for Permitted Liens, Debtor has not executed any prior transfer, assignment, pledge, security interest, or hypothecation covering the Collateral or any interest in the Collateral.

(d)

Authority. Debtor has full power and authority to execute this Agreement without breaching any material agreement to which Debtor is a party.

(e)

Status of Accounts. The Accounts arise from sale of Inventory or Equipment or the performance of services by Debtor.

(f)

Quality of Collateral. Debtor will not submit or represent to Secured Party any item of Collateral as being eligible to form part of the Borrowing Base (as defined in the Credit Agreement) when it does not meet the requirements set forth in the Credit Agreement.

(g)

No Defenses. The amounts due Debtor under the Collateral are not subject to any setoff, counterclaim, defense, allowance, or adjustment (other than discounts for prompt payment shown on the invoice) or to any material dispute, objection, or complaint by any Obligor.

(h)

Additional Collateral. The delivery at any time by Debtor to Secured Party of Collateral or of additional specific descriptions of certain Collateral will constitute a representation and warranty by

Debtor to Secured Party under this Agreement that the representations and warranties of this Section 7 are true and correct in all material respects with respect to each item of such Collateral.

Covenants. Debtor further covenants and agrees with Secured Party that so long as Secured Party is committed to extend credit to Debtor under the Credit Agreements and thereafter until the Obligation is paid and performed in full and all commitments to lend under the Credit Agreements have terminated Debtor shall:

(a)

Relocation of Office or Books and Records; Change of Name or Address. Give Secured Party 30 days prior written notice of (i) any proposed relocation of its principal place of business or chief executive office, (ii) any proposed relocation of the place where its books and records relating to the Collateral is kept, (iii) a change of its name, and (iv) any proposed relocation of any of the Collateral (other than sales of Inventory in the ordinary course of business or as permitted by the Credit Agreements) to a location other than those set out in Schedule 1.

(b)

Material Change. Promptly notify Secured Party of any change in any material fact or circumstance represented or warranted by Debtor with respect to any of the Collateral.

(c)

Record of Collateral. Maintain at its chief executive office a current record of where all Collateral is located and permit Secured Party or its representatives to inspect and make copies from such records pursuant to the Credit Agreement and furnish to Secured Party, from time to time, such documents, lists, descriptions, certificates, and other information necessary or helpful to keep Secured Party informed with respect to the identity, location, status, condition, terms of, parties to, and value of the Collateral.

(d)

Adverse Claim. Promptly notify Secured Party of any claim, action, or proceeding challenging the Security Interest or affecting title to all or any material portion of the Collateral or the Security Interest and, at Secured Party's request, appear in and defend any such action or proceeding at Debtor's expense.

(e)

Hold Collateral In Trust. Upon the occurrence and during the continuation of a Default, hold in trust (and not commingle with its other assets) for Secured Party all Collateral that is chattel paper, instruments or documents of title at any time received by it and promptly deliver same to Secured Party unless Secured Party at its option gives Debtor written permission to retain that Collateral. Upon the occurrence and during the continuation of a Default, at Secured Party's request, each contract, chattel paper, instrument or document of title so retained shall be marked to state that it is assigned to Secured Party and each instrument shall be endorsed to the order of Secured Party (but failure to so ▇▇▇▇ or endorse shall not impair the Security Interest).

(f)

No Assignment. Without Secured Party's prior written consent, not sell, assign, or otherwise dispose of, or permit the sale, assignment, or disposition of, any Collateral except as permitted by the Credit Agreements.

(g)

Permitted Liens. Not create or permit the creation of, or allow the existence of, any Lien upon or against any of the Collateral except for Permitted Liens.

(h)

Further Assurances. From time to time promptly execute and deliver to Secured Party all other assignments, certificates, supplemental documents, and financing statements, and do all other acts or things as Secured Party may reasonably request in order to create, evidence, perfect, continue, or maintain the existence and priority of the Security Interest including amendments to Schedule 1.

(i)

Perform Obligations. Perform all of its obligations under or in connection with the Collateral in accordance with customary business practices.

(j)

Amendment. Not amend, alter, or modify, or permit the amendment, alteration or modification of, any material portion (individually or collectively) of the Collateral, except in the ordinary

course of business, without Secured Party's prior written consent as to the form and content of the amendment, alteration, or modification.

(k)

Impairment of Collateral. Not do or permit any act which would impair any material portion of the Collateral.

(l)

Default Under Collateral. Promptly notify Secured Party of any default or event of default by Debtor or any other party under or in connection with any material portion (individually or collectively) of the Collateral and immediately use reasonable efforts to remedy the same or immediately demand that the same be remedied.

Default; Remedies. Upon the occurrence of a Default, subject to the terms and conditions of the Credit Agreements, Secured Party has the following cumulative rights and remedies under this Agreement.

(a)

Debtor's Agent. Secured Party shall be deemed to be irrevocably appointed as Debtor's agent and attorney-in-fact with all right and power to enforce all of Debtor's rights and remedies under or in connection with the Collateral. All reasonable costs, expenses and liabilities incurred and all payments made by Secured Party as Debtor's agent and attorney-in-fact, including, without limitation, reasonable attorney's fees and expenses, shall be considered a loan by Secured Party to Debtor which shall be repayable on demand and shall accrue interest at the Default Rate and shall be part of the Obligation.

(b)

Account Debtors and Obligors. Secured Party may notify or require each account debtor or other Obligor to make payment directly to Secured Party and Secured Party may take control of the proceeds paid to Secured Party. Until Secured Party elects to exercise these Rights, Debtor is authorized to collect and enforce the Collateral and to retain and expend all payments made on Collateral. After Secured Party elects to exercise these rights, Secured Party shall have the Right in its own name or in the name of Debtor to (i) compromise or extend time of payment with respect to all or any portion of the Collateral for such amounts and upon such terms as Secured Party may reasonably determine, (ii) demand, collect, receive, receipt for, ▇▇▇ for, compound, and give acquittance for any and all amounts due or to become due with respect to Collateral, (iii) take control of cash and other proceeds of any Collateral, (iv) endorse Debtor's name on any notes, acceptances, checks, drafts, money orders, or other evidences of payment on Collateral that may come into Secured Party's possession, (v) sign Debtor's name on any invoice or ▇▇▇▇ of lading relating to any Collateral, on any drafts against Obligors or other Persons making payment with respect to Collateral, on assignments and verifications of accounts or other Collateral and on notices to Obligors making payment with respect to Collateral, (vi) send requests for verification of obligations to any Obligor, and (vii) do all other acts and things reasonably necessary to carry out the intent of this Agreement. If any Obligor fails to make payment on any Collateral when due, Secured Party is authorized, in its sole discretion, either in its own name or in Debtor's name, to take such action as Secured Party reasonably shall deem appropriate for the collection of any amounts owed with respect to Collateral or upon which a delinquency exists. Regardless of any other provision of this Agreement, however, Secured Party shall not be liable for its failure to collect, or for its failure to exercise diligence in the collection of, any amounts owed with respect to Collateral except for its own fraud, gross negligence, willful misconduct or violation of any Law, nor shall it be under any duty whatever to anyone except Debtor to account for funds that it shall actually receive under this Agreement. A receipt given by Secured Party to any Obligor shall be a full and complete release, discharge, and acquittance to such Obligor, to the extent of any amount so paid to Secured Party. Secured Party may apply or set off amounts paid and the deposits against any liability of Debtor to Secured Party.

(c)

UCC Rights. Secured Party may exercise any and all Rights available to a secured party under the UCC, in addition to any and all other Rights afforded by this Agreement and the other Loan Documents, at law, in equity, or otherwise, including, without limitation, (i) requiring Debtor to assemble all or part of the Collateral and make it available to Secured Party at a place to be designated by Secured Party which is reasonably convenient to Debtor and Secured Party, (ii) applying by appropriate judicial proceedings for appointment of a receiver for all or part of the Collateral, (iii) applying to the Obligation any cash held by Secured Party under this Agreement, (iv) reducing any claim to judgment, (v) exercising the rights of offset or banker's Lien against the interest of Debtor in and to every account and other

property of Debtor in Secured Party's possession to the extent of the full amount of the Obligation, (vi) foreclosing the Security Interest and any other liens Secured Party may have or otherwise realize upon any and all of the rights Secured Party may have in and to the Collateral, or any part thereof, (vii) disclaiming any and all warranties upon disposition of any Collateral and (viii) bringing suit or other proceedings before any Tribunal either for specific performance of any covenant or condition contained in any of the Loan Documents or in aid of the exercise of any right granted to Secured Party in any of the Loan Documents.

(d)

Notice. Reasonable notification of the time and place of any public sale of the Collateral, or reasonable notification of the time after which any private sale or other intended disposition of the Collateral is to be made, shall be sent to Debtor and to any other Person entitled to notice under the UCC; provided that, if any of the Collateral threatens to decline speedily in value or is of the type customarily sold on a recognized market, Secured Party may sell or otherwise dispose of the Collateral without notification, advertisement, or other notice of any kind. It is agreed that notice sent or given not less than ten calendar days prior to the taking of the action to which the notice relates is reasonable notification and notice for the purposes of this subparagraph. It shall not be necessary that the Collateral be at the location of the sale.

(e)

Application of Proceeds. Secured Party shall apply the proceeds of any sale or other disposition of the Collateral under this Section 9 as follows: First, to the payment of all its reasonable expenses incurred in retaking, holding, and preparing any of the Collateral for sale(s) or other disposition, in arranging for such sale(s) or other disposition, and in actually selling or disposing of the same (all of which are part of the Obligation); second, toward repayment of amounts reasonably expended by Secured Party under Section 10; and third, toward payment of the balance of the Obligation in the order and manner specified in the Credit Agreement. Any surplus remaining shall be delivered to Debtor or as a court of competent jurisdiction may direct.

(f)

Sale. Secured Party's sale of less than all the Collateral shall not exhaust Secured Party's Rights under this Agreement and Secured Party is specifically empowered to make successive sales until all the Collateral is sold. If the proceeds of a sale of less than all the Collateral shall be less than the Obligation, this Agreement and the Security Interest shall remain in full force and effect as to the unsold portion of the Collateral just as though no sale had been made. In the event any sale under this Agreement is not completed or is, in Secured Party's opinion, defective, such sale shall not exhaust Secured Party's rights under this Agreement and Secured Party shall have the right to cause a subsequent sale or sales to be made. Any and all statements of fact or other recitals made in any ▇▇▇▇ of sale or assignment or other instrument evidencing any foreclosure sale under this Agreement as to nonpayment of the Obligation, or as to the occurrence of any Default, or as to Secured Party's having declared all of such Obligation to be due and payable, or as to notice of time, place and terms of sale and the properties to be sold having been duly given, or as to any other act or thing having been duly done by Secured Party, shall be taken as prima facie evidence of the truth of the facts so stated and recited. Secured Party may appoint or delegate any one or more Persons as agent to perform any act or acts necessary or incident to any sale held by Secured Party, including the sending of notices and the conduct of sale, but such acts must be done in the name and on behalf of Secured Party.

(g)

Liability/Existence of Default. Regarding the existence of any Default for purposes of this Agreement, Debtor agrees that the Obligors on any Collateral may rely upon written certification from Secured Party that such a Default exists. Debtor expressly agrees that Secured Party shall not be liable to Debtor for any claims, damages, costs, expenses or causes of action of any nature whatsoever in connection with, arising out of, or related to Secured Party's exercise of any rights, powers or remedies under any Loan Document except for its own fraud, gross negligence, willful misconduct or violation of any Law.

10.

Other Rights of Secured Party.

(a)

Performance. In the event Debtor fails to preserve the priority of the Security Interest in any of the Collateral, or, upon the occurrence and during the continuance of a Default, otherwise fails to perform any of its obligations under the Loan Documents with respect to the Collateral, then Secured Party

may (but is not required to) prosecute or defend any suits in relation to the Collateral or take any other action which Debtor is required to take under the Loan Documents, but has failed to take. Any sum which may be reasonably expended or paid by Secured Party under this subparagraph (including, without limitation, court costs and reasonable attorneys' fees and expenses) shall bear interest from the date of expenditure or payment at the Default Rate until paid and, together with such interest, shall be payable by Debtor to Secured Party upon demand and shall be part of the Obligation.

(b)

Collateral in Secured Party's Possession. If, upon the occurrence and during the continuance of a Default, any Collateral comes into Secured Party's possession, Secured Party may use such Collateral for the purpose of preserving it or its value pursuant to the order of a court of appropriate jurisdiction or in accordance with any other Rights held by Secured Party in respect of such Collateral. Debtor covenants to promptly reimburse and pay to Secured Party, at Secured Party's request, the amount of all reasonable expenses incurred by Secured Party in connection with its custody and preservation of such Collateral, and all such expenses, costs, Taxes, and other charges shall bear interest at the Default Rate until repaid and, together with such interest, shall be payable by Debtor to Secured Party upon demand and shall be part of the Obligation. However, the risk of accidental loss or damage to, or diminution in value of, Collateral is on Debtor, except for Secured Party's own fraud, gross negligence, willful misconduct or violation of any Law. Provided that Secured Party acts in accordance with all applicable Laws, Secured Party shall have no liability for failure to obtain or maintain insurance, nor to determine whether any insurance ever in force is adequate as to amount or as to the risks insured. With respect to Collateral that is in the possession of Secured Party, except for its own fraud, gross negligence, willful misconduct or violation of any Law, Secured Party shall have no duty to fix or preserve Rights against prior parties to such Collateral and shall never be liable for any failure to use diligence to collect any amount payable in respect of such Collateral, but shall be liable only to account to Debtor for what it may actually collect or receive thereon.

(c)

Subrogation. If any of the Obligation is given in renewal or extension or applied toward the payment of indebtedness secured by any Lien, Secured Party shall be, and is hereby, subrogated to all of the Rights, titles, interests, and Liens securing the indebtedness so renewed, extended, or paid.

11.

Miscellaneous.

(a)

Reference to Miscellaneous Provisions. This Agreement is one of the "Loan Documents" referred to in the Credit Agreements, and, therefore, this Agreement is subject to the applicable provisions of Section 14 of the Credit Agreements, all of which are incorporated in this Agreement by reference the same as if set forth in this Agreement verbatim.

(b)

Term. Upon full and final payment of the Obligation and final termination of the Secured Party's commitment to lend under the Credit Agreement without Secured Party having exercised its rights under this Agreement, this Agreement shall terminate; provided that no Obligor on any of the Collateral shall be obligated to inquire as to the termination of this Agreement, but shall be fully protected in making payment directly to Secured Party, which payment shall be promptly paid over to Debtor after termination of this Agreement.

(c)

Actions Not Releases. The Security Interest and Debtor's obligations and Secured Party's Rights under this Agreement shall not be released, diminished, impaired, or adversely affected by the occurrence of any one or more of the following events: (i) the taking or accepting of any other security or assurance for any or all of the Obligation; (ii) any release, surrender, exchange, subordination, or loss of any security or assurance at any time existing in connection with any or all of the Obligation; (iii) the modification of, amendment to, or waiver of compliance with any terms of any of the other Loan Documents without the consent of Debtor, except as required therein; (iv) the insolvency, bankruptcy, or lack of corporate or trust power of any party at any time liable for the payment of any or all of the Obligation, whether now existing or hereafter occurring; (v) any renewal, extension, or rearrangement of the payment of any or all of the Obligation, either with or without notice to or consent of Debtor, or any adjustment, indulgence, forbearance, or compromise that may be granted or given by Secured Party to Debtor, in each case, except as required by the Loan Documents; (vi) any neglect, delay, omission, failure,

or refusal of Secured Party to take or prosecute any action in connection with any other agreement, document, guaranty, or instrument evidencing, securing, or assuring the payment of all or any of the Obligation; (vii) any failure of Secured Party to notify Debtor of any renewal, extension, or assignment of the Obligation or any part thereof, or the release of any security under any other document or instrument, or of any other action taken or refrained from being taken by Secured Party against Debtor or any new agreement between Secured Party and Debtor, it being understood that, except as expressly required by the Credit Agreement, Secured Party shall not be required to give Debtor any notice of any kind under any circumstances whatsoever with respect to or in connection with the Obligation, including, without limitation, notice of acceptance of this Agreement or any Collateral ever delivered to or for the account of Secured Party under this Agreement; (viii) the illegality, invalidity, or unenforceability of all or any part of the Obligation against any third party obligated with respect thereto by reason of the fact that the Obligation, or the interest paid or payable with respect thereto, exceeds the amount permitted by Law, the act of creating the Obligation, or any part thereof, is ultra ▇▇▇▇▇, or the officers, partners, or trustees creating same acted in excess of their authority, or for any other reason; or (ix) if any payment by any party obligated with respect thereto is held to constitute a preference under applicable Laws or for any other reason Secured Party is required to refund such payment or pay the amount thereof to someone else.

(d)

Waivers. Except to the extent expressly otherwise provided in this Agreement or in other Loan Documents, Debtor waives (i) any Right to require Secured Party to proceed against any other Person, to exhaust its Rights in Collateral, or to pursue any other Right which Secured Party may have; (ii) with respect to the Obligation, presentment and demand for payment, protest, notice of protest and nonpayment, notice of acceleration, and notice of the intention to accelerate; and (iii) all Rights of marshaling in respect of any and all of the Collateral.

(e)

Financing Statement. Secured Party shall be entitled at any time to file this Agreement or a carbon, photographic, or other reproduction of this Agreement, as a financing statement, but the failure of Secured Party to do so shall not impair the validity or enforceability of this Agreement.

(f)

Amendments. This Agreement may only be amended by a writing executed by Debtor and Secured Party.

(g)

Multiple Counterparts. This Agreement may be executed in any number of identical counterparts. Each counterpart shall be deemed an original for all purposes and all counterparts, collectively, shall constitute one Agreement. In making proof of this Agreement, it shall not be necessary to produce or account for more than one set of counterpart signatures.

(h)

Parties Bound. This Agreement shall be binding on Debtor and its successors and assigns and shall inure to the benefit of Secured Party and its successors and assigns. The obligations and agreements of Debtor under this Agreement shall be binding upon its successors and assigns, and delivery or other accounting of Collateral to Debtor shall discharge Secured Party of all liability therefor.

(i)

Assignment.

Debtor may not, without Secured Party's prior written consent, assign any Rights, duties, or obligations under this Agreement.

(j)

Notice. Any notice or communication required or permitted under this Agreement must be given as prescribed in the Credit Agreements.

(k)

Governing Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS MUST BE CONSTRUED--AND THEIR PERFORMANCE ENFORCED--UNDER TEXAS LAW.

(l)

Amended, Restated and Combined Agreement. This Agreement amends, restates and combines the Prior Agreement such that this Agreement secures the Obligations under both Credit Agreements.

THE STATE OF TEXAS

KNOW ALL MEN BY THESE PRESENTS:

COUNTY OF ▇▇▇▇▇▇

THAT THE UNDERSIGNED, PHYTO-SOURCE, L.P., a Texas limited partnership (hereinafter called "Grantor," whether one or more), whose mailing address is 12▇▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇▇., ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, for and in consideration of the debt hereinafter described, has granted, bargained, sold and conveyed, and by these presents does grant, bargain, sell and convey, in trust, unto ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇ of ▇▇▇▇▇▇ County, Texas, as Trustee, and unto his successors in the trust hereby created and unto his or their assigns and the heirs of such assigns (all of whom are hereinafter called "Trustee"), for the benefit of SOUTHWEST BANK OF TEXAS, N.A., a national banking association, the address of which is 5 Post Oak, 44▇▇ ▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ ▇nd whose mailing address is P.▇. ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇ (hereinafter called "Beneficiary"), all the property described in Exhibit "A" attached hereto and made a part hereof for all purposes. To have and to hold unto Trustee and his substitutes, successors and assigns the property described in Exhibit "A", together with any and all personal property now or hereafter located thereon owned by Grantor and any and all buildings and improvements of every kind and character now or hereafter situated or placed thereon (including, but not limited to, any and all plumbing, electrical, heating, cooling and other fixtures, equipment (excluding the equipment described on Schedule 3 to the Security Agreement dated as of even date herewith and appliances), and all replacements of and additions thereto, and all of Grantor's rights with respect to utility capacity, utilities and utility taps, wastewater capacity, proceeds arising from any claim pursuant to any policy of title insurance covering the property described in Exhibit "A" and all and singular the rights, privileges, hereditaments, appurtenances, rents, revenues, profits and income thereunto now or hereafter incident or belonging thereto (collectively referred to herein as the "Mortgaged Property"), forever and Grantor does hereby bind itself, it's heirs, successors, assigns and legal representatives to warrant and forever defend, all and singular the Mortgaged Property unto the Trustee, his substitutes or successors and assigns forever, against the claim or claims of all persons to claim the same or any part thereof. It is hereby agreed that to the extent permitted by law all of the foregoing property is to be deemed and held to be a part of and affixed to the realty.

This conveyance is made in trust, however, to secure and enforce the (A) payment of two promissory notes (hereinafter referred to as "Notes," whether one or more) executed by Grantor, payable to the order of Beneficiary: (i) a Revolving Note in the principal amount of $1,500,000.00; (ii) a Term Note in the principal amount of $3,000,000.00, each bearing interest and being payable as provided therein each of even date herewith and (B) Obligations under that certain Credit Agreement ("Credit Agreement") between Grantor and Beneficiary of even date herewith (collectively, together with this Deed of Trust, the "Credit Documents").

This Deed of Trust shall secure, in addition to the Notes, all funds hereafter advanced by Beneficiary to or for the benefit of Grantor, as contemplated by any covenant or provision herein contained or for any other purpose, and all other indebtedness, of whatever kind or character, owing or which may hereafter become owing by Grantor to Beneficiary, whether such indebtedness is evidenced by note, open account, overdraft, endorsement, surety agreement, guaranty or otherwise, it being contemplated that Grantor may hereafter become indebted to Beneficiary in further sum or sums, including without limitation under the Credit Agreement. All indebtedness secured hereby shall be payable in ▇▇▇▇▇▇ County, Texas, until Beneficiary gives written notice to Grantor designating another place of payment; and unless otherwise provided in the instrument evidencing said indebtedness, shall bear interest at the maximum non-usurious rate allowed by applicable law. If the Notes or any other indebtedness secured hereby shall be collected by legal proceedings or through a probate or bankruptcy court or shall be placed in the hands of an attorney for collection after maturity, whether matured by the expiration of time or by the option given to the Beneficiary to mature same, Grantor agrees that all attorney's or collection fees as provided for in the Credit Documents shall be paid by Grantor and shall be a part of the indebted-ness secured hereby. This Deed of Trust shall also secure all renewals, rearrangements and extensions of any of the indebtedness secured hereby.

Better to secure payment of said indebtedness, Grantor does hereby covenant and agree with the Beneficiary and with the Trustee as follows:

(1)

Grantor will pay all of the indebtedness secured hereby, together with the interest and other appur-tenant charges thereon, when the same shall become due in accordance with the terms of the Credit Documents or other instruments evidencing said indebtedness or evidencing any renewal or extension of the same or any part thereof.

(2)

Grantor has, in its own right, good and indefeasible title in fee simple to the Mortgaged Property, which is free from encumbrance superior to the liens and security interests hereby created unless otherwise herein provided and have full right and authority to make this conveyance. Grantor shall at all times comply with and perform all obligations under any applicable laws, statutes, regulations, covenants, restrictions or ordinances relating to the Mortgaged Property. Grantor acknowledges the existence of that certain Deed of Trust, Security Agreement and Financing Statement dated July 17, 2001 (the "Existing Deed of Trust") and filed for record in the Deed Records of ▇▇▇▇▇▇ County, Texas by Forbes Medi-Tech (USA), Inc. ("Forbes") affecting the Mortgaged Property. The lien and security interest created by the Existing Deed of Trust shall be subordinate in all respects to the lien and security interest granted by this Deed of Trust pursuant to the terms of that certain Subordination Agreement dated as of even date herewith by and between Grantor, Beneficiary and Forbes.

(3)

Grantor will keep all buildings and other property covered by this Deed of Trust insured against fire, lightning, tornado, hail, explosion and against such other risks as Beneficiary may require, all in amounts approved by Beneficiary. In addition to the above required insurance, Grantor will keep all buildings and other property covered by this Deed of Trust and all personal property covered hereby or covered by any other instrument securing payment of the Notes insured for the term of the Credit Documents with flood insurance in an amount at least equal to the outstanding principal of the Notes or to the maximum limit of coverage made available with respect to the particular type of property under the National Flood Insurance Act of 1968, whichever is less. Such flood insurance is required hereunder only when such property is located or to be located in an area that has been identified by the Secretary of Housing and Development as an area having special flood hazards and in which flood insurance has been made available under the National Flood Insurance Act of 1968. Such insurance is to be written in form and in companies acceptable to the Beneficiary with mortgagee clauses of standard form in favor of Beneficiary and will deliver the policies of insurance to the Beneficiary promptly as issued; and, in case the Grantor fails so to do, Beneficiary, at its option, may procure such insurance at Grantor's expense. All renewal and substitute policies of insurance shall be delivered at the office of Beneficiary, premiums paid, at least ten (10) days before termination of policies theretofore delivered to Beneficiary. All policies shall provide, by way of riders, endorsements or other-wise, that the insurance provided thereby shall not be terminated, reduced or otherwise limited, regardless of any breach of the representations and agreements set forth therein and that the interest of the Beneficiary will not be invalidated by any act or omission of the Grantor and that no such policy shall be canceled, endorsed or amended to any extent unless the issuer thereof shall have first given Beneficiary at least fifteen (15) days prior written notice. In case Grantor fails to furnish such policies, Beneficiary, at its option, may procure such insurance at Grantor's expense. In case of loss, Beneficiary, at its option, shall be entitled to receive and retain the proceeds of the insur-ance policies, applying the same toward payment of said indebtedness as Beneficiary shall see fit or, at Beneficiary's option, Beneficiary may pay the same over wholly or in part to Grantor for the repair of said building or buildings or for the erection of a new building or buildings in their place or for any other purpose satisfactory to Beneficiary, but Beneficiary shall not be obligated to see to the proper application of any amount paid over to Grantor. If Beneficiary elects to allow payment of all or part of such proceeds to Grantor, such payments shall be disbursed on such terms and subject to such conditions as Beneficiary may specify. Should Beneficiary elect to allow Grantor to repair such damage, Grantor agrees that, regardless of whether any insurance proceeds payable to it are sufficient to pay the costs of repair and restoration of the Mortgaged Property, Grantor shall promptly commence and carry out the repair, replacement, restoration and rebuilding of any and all of the Mortgaged Property damaged or destroyed by fire or other casualty so as to return same, to the extent practicable, to its condition immediately prior to such damage to or destruction thereof. Grantor shall not permit or carry on any activities within or relating to the Mortgaged Property that is prohibited by the terms of any insurance policy covering any part of the Mortgaged Property or which permits cancellation of or increase in the premium payable for any insurance policy covering any part of the Mortgaged Property. In the event of a foreclosure of this Deed of Trust, the purchaser of the Mortgaged Property shall succeed to all the rights of Grantor, including any right to unearned premiums, in and to all policies of insurance assigned and delivered to Beneficiary pursuant to the provisions of this Deed of Trust. Regardless of the types or amounts of insurance required and approved by Beneficiary, Grantor shall assign and deliver to Beneficiary all policies of insurance that insure against any loss or damage to the Mortgaged Property as collateral and further security for the payment of the

Notes and any other indebtedness secured hereby. Grantor shall also obtain and maintain in force and effect such liability and other insurance policies and protection as Beneficiary may from time to time specify.

(4)

Grantor will pay all taxes and assessments against the Mortgaged Property including, without limitation, all taxes in lieu of ad valorem taxes as the same become due and payable and provide Beneficiary with copies of paid tax receipts or tax certificates evidencing payment, from each taxing authority having jurisdiction over the Mortgaged Property. If Grantor fails to provide such evidence of payment within thirty (30) days from the date such taxes are due and payable, Beneficiary may procure a tax certificate(s) at Grantor's sole cost and expense. In the event of the passage after date of this Deed of Trust of any law by the State of Texas deducting from the Mortgaged Property for the purposes of taxation any lien thereon or changing in any way the laws now in force for the taxation of mortgages, deeds of trust or indebtedness secured thereby for State or local purposes or the manner of the operation of any such taxes so as to affect the interest of Beneficiary, then, and in such event, Grantor shall bear and pay the full amount of such taxes. If Grantor fails to pay any such taxes and assessments including, without limitation, taxes in lieu of ad valorem taxes and taxes against this Deed of Trust or said indebtedness secured hereby, Beneficiary may pay the same, together with all costs and penalties thereon, at Grantor's expense; provided, how-ever, that if, for any reason, payment by Grantor of any such new or additional taxes would be unlawful or if the payment thereof would constitute usury or render said indebtedness wholly or partially usurious under any of the terms or provisions of the Credit Documents or this Deed of Trust or otherwise, Beneficiary may, at its option, declare the indebtedness secured hereby, with all accrued interest thereon, to be immediately due and payable or Beneficiary may, at its option, pay the amount or portion of such taxes as renders the indebtedness secured hereby unlawful or usurious, in which event Grantor shall concurrently therewith pay the remaining lawful and non-usurious portion or balance of said taxes.

(5)

All judgments, decrees, awards or payment for injury or damage to the Mortgaged Property and all awards pursuant to proceeding for condemnation thereof, including interest thereon, are hereby assigned in their entirety to the Beneficiary, who may apply the same first to reimbursement of all costs and expenses incurred by Beneficiary in connection with such condemnation proceeding and the balance to the indebtedness secured hereby in such manner as it may elect; and Beneficiary is hereby authorized, in the name of Grantor, to execute and deliver valid acquittances for and to appeal from any such award, judgment or decree. Grantor shall promptly notify Beneficiary of the institution or threatened institution of any proceeding for the condemnation of any of the Mortgaged Property. Beneficiary shall have the right to participate in any such condemnation proceeding.

(6)

If, while this trust is in force, the title of the Trustee to the Mortgaged Property or any part thereof shall be endangered or shall be attacked directly or indirectly, Grantors hereby authorize the Beneficiary, at Grantor's expense, to take all necessary and proper steps for the defense of said title, including the employment of counsel, the prosecution or defense of litigation and the compromise or discharge of claims made against said title.

(7)

If, in pursuance of any covenant herein contained, the Beneficiary shall pay out any money chargeable to Grantor or subject to reimbursement by Grantor under the terms of said covenant or agreement, Grantor will repay the same to Beneficiary immediately at the place where the payments under the Credit Documents or other indebtedness hereby secured are payable, together with interest thereon at the maximum non-usurious rate allowed by applicable law from and after the date of Beneficiary's making such payment. The sum of each such payment shall be added to the Notes and thereafter shall form a part of the same; and it shall be secured by this Deed of Trust and by subrogation to all the rights of the person, corporation or body politic receiving such payment.

(8)

Grantor will keep every part of the Mortgaged Property in good condition and presenting a good appearance, making promptly all repairs, renewals and replacements necessary to such end and doing promptly all else necessary to such end; but Grantor will discharge all claims for labor performed and material furnished therefor; and will not suffer any lien of mechanics or materialmen therefor to attach to any part of the Mortgaged Property; and Grantor will guard every part of the Mortgaged Property from removal, destruction and damage, and will not do or suffer to be done any act whereby the value of any part of the Mortgaged Property may be lessened. No building or other property now or hereafter covered by the lien of this Deed of Trust shall be removed, demolished or materially altered or enlarged, nor shall any new building be constructed, without the prior written consent of Beneficiary. Grantor shall not initiate, join in or consent to any change in any private restrictive covenants, zoning ordinances or other public or private restrictions limiting or defining the uses that may be made of the Mortgaged Property or any part thereof without the prior written consent of Beneficiary. Beneficiary and its agents or

representatives shall have access to the Mortgaged Property at all reasonable times in order to inspect same and verify Grantor's compliance with their duties and obligations under this Deed of Trust. Grantor shall not, without prior written approval of Beneficiary, grant, convey or otherwise create or permit to be created, any type of mortgage, lien, security interest or other encumbrance on any of the Mortgaged Property, regardless whether same shall be inferior and subordinate to the liens and security interests of Beneficiary in and to the Mortgaged Property.

Grantor shall not sell, transfer, assign or mortgage all or any portion of the Mortgaged Property (including any utilities, utility capacity, utility taps or any rights or interests thereto), nor shall Grantor grant any easement, right-of-way or file of record any restrictive covenants or restrictions whatsoever with respect to the Mortgaged Property, nor shall Grantor rent or lease any or all of the Mortgaged Property for a period in excess of one (1) year without the express written consent of the Beneficiary. If Grantor is a corporation or partnership, any sale of corporate stock or partnership interests shall constitute a sale of the Mortgaged Property for the purposes hereof.

(10)

In the event the ownership of the Mortgaged Property or any part thereof becomes vested in a per-son other than Grantor, Beneficiary may, without notice to Grantor, deal with such successor or successors in interest with reference to this Deed of Trust and to said indebtedness in the same manner as with Grantor, without in any way vitiating or discharging Grantor's liability hereunder or upon said indebtedness. No sale of the Mortgaged Property and no forbearance on the part of Beneficiary and no extension of the time for the payment of said indebtedness given by Beneficiary shall operate to release, discharge, modify, change or affect, either in whole or in part, any original liability of Grantor or the liability of the guarantors or sureties of Grantor or of any other party liable for payment of said indebtedness or any part thereof.

(11)

In the event Grantor shall default in the prompt payment when due of the indebtedness secured hereby or any part thereof or any part of any indebtedness of Grantor to any other person or entity, or fail to keep and perform any of the covenants or agreements herein contained; or in the event any of the representations or warranties made to Beneficiary or set forth herein prove to be false; or in the event Grantor or any person liable for the indebtedness secured hereby or any part thereof file a voluntary petition in bankruptcy, make an assignment for the benefit of any creditor or are adjudicated a bankrupt or insolvent or if the Mortgaged Property is placed under control or in the custody of any court or if the Grantor abandons any of the Mortgaged Property; then the Beneficiary, at its option, may declare the entire indebtedness secured hereby immediately due and payable, where-upon it shall be so due and payable.

(12)

All of the covenants and agreements of Grantor set forth herein shall survive the execution and delivery of this Deed of Trust and shall continue in force until the indebtedness secured hereby is paid in full. Accordingly, if Grantor shall perform faithfully each and all of the covenants and agreements herein contained, then, and then only, this conveyance shall become null and void and shall be released in due form at Grantor's expense; otherwise, it shall remain in full force and effect. No release of this conveyance or the lien thereof shall be valid unless executed by the Beneficiary.

(13)

If Grantor shall fail to perform faithfully any covenant or agreement herein contained, Grantor hereby authorizes and empowers the Trustee and each and all of his successors in this trust, at the request of the Beneficiary, at any time when Grantor shall be in default in the performance of any such covenant or agreement, to sell the Mortgaged Property at public vendue to the highest bidder for cash at the door of the County Courthouse of the county in Texas in which the Mortgaged Property or any part thereof is situated, as herein described, between the hours of 10:00 a.m. and 4:00 p.m. (as more particularly described in the hereinafter described notice) of the first Tuesday of any month, after advertising the time, place and terms of said sale and the Mortgaged Property to be sold, by posting (or by having some person or persons acting for him post) for at least twenty-one (21) days preced-ing the date of the sale, written or printed notice of the proposed sale at the Courthouse of said county in the area of the Courthouse designated by the Commissioner's Court as the area for sales pursuant to Section 51.002 of the Texas Property Code and if no area is designated by the Commissioner's Court, the notice of sale shall designate the area of the Courthouse where the sale is to take place; in addition to such posting of notice, the holder of the indebt-edness hereby secured shall, at least twenty-one (21) days preceding the date of sale: (a) serve written or printed notice of the proposed sale by certified mail on Grantor and on each other debtor, if any, obligated to pay the indebtedness hereby secured according to records of such holder, which shall state the earliest time at which the sale will begin and the sale shall begin at such time or not later than three (3) hours after that time, and (b) file a copy of the notice of proposed sale with the County Clerk or County Clerks of the county or counties where such notice was posted. Service of such notice shall be completed upon deposit of the

notice, enclosed in a postpaid wrapper, prop-erly addressed to Grantor and such other debtors at their most recent address or addresses as shown by the records of the holder of the indebtedness hereby secured, in a post office or official depository under the care and custody of the United States Postal Service. The affidavit of any person having knowledge of the facts to the effect that such service was completed shall be prima facie evidence of the fact of service. The provisions hereof with respect to posting and giving notices of sale are intended to comply with the provisions of Section 51.002 of the Property Code of the State of Texas, and, in the event the requirement for any notice under such Section 51.002 shall be eliminated or the prescribed manner of giving same modified by future amendment to or adoption of any statute superseding such Section 51.002, the requirement for such particular notice shall be deemed stricken from or modified in this instrument in conformity with such amendment or superseding statute, effective as of the effective date of same. The manner herein prescribed for serving or giving any notice, other than that to be posted or caused to be posted by the Trustee, shall not be deemed exclusive, but such notice or notices may be given in any other manner which may be permitted by applicable law. Grantor agrees that no notice of any sale other than as set out in this paragraph need be given by Trustee, Beneficiary or any other person. Grantor hereby designates as its address for the purposes of such notice the address set out in the first paragraph hereof and agree that such address shall be changed only by depositing notice of such change, enclosed in a postpaid wrapper, in a post office or official depository under the care and custody of the United States Postal Service, certified mail, postage prepaid, return receipt requested, addressed to Beneficiary at the address for Beneficiary set out herein (or to such other address as Beneficiary may have designated by notice given as above provided to Grantor and such other debtors), any such notice of change of address of Grantor or other debtors shall be effective upon receipt by Beneficiary. Any change of address of Beneficiary shall be effective three (3) business days after deposit thereof in the above described manner in a post office or official depository under the care and custody of the United States Postal Service. Grantor does hereby authorize and empower Trustee and each and all of his successors in this trust to sell the Mortgaged Property or any interest or estate in the Mortgaged Property, together or in lots or parcels, as such Trustee shall deem expedient and to execute and deliver to the purchaser or purchasers of the Mortgaged Property good and sufficient deed or deeds of conveyance thereof and bills of sale with covenants of general warranty binding on Grantor and Grantor's heirs, legal representatives, successors and assigns. Trustee making such sale shall receive the proceeds thereof and shall apply the same as follows: (a) he shall pay the reasonable expense of executing this trust, including a commission to himself of five percent (5%) of the gross proceeds of the sale; (b) after paying such expenses, he shall pay, so far as may be possible, the indebtedness hereby secured, discharging first that portion of said indebtedness arising under the covenants or agreements herein contained and not evidenced by note; (c) then, he shall pay, so far as may be possible, the indebtedness secured by any liens equal or superior to the lien created hereby; and (d) he shall pay the residue, if any, to Grantor, its heirs, legal representatives, successors or assigns. Payment of the purchase price to the Trustee shall satisfy the obligation of the purchaser at such sale therefor and he shall not be bound to look after the application thereof.

(14)

If the herein-named Trustee shall die or become disqualified from acting in the execution of this trust or shall fail or refuse to execute the same when requested by Beneficiary so to do or if, for any reason, Beneficiary shall prefer to appoint a substitute trustee to act instead of the herein-named Trustee, Beneficiary shall have full power to appoint, by written instrument, a substitute trustee and, if necessary, several substitute trustees in succession, who shall succeed to all the estate, rights, powers and duties of Trustee named herein and no notice of such appointment need be given to Grantor or to any other person or filed for record in any public office. Such appointment may be executed by any authorized agent of the Beneficiary; and such appointment executed in its behalf by any officer of such entity shall be conclusively presumed to be executed with authority and shall be valid and sufficient without proof of any action by the board of directors or any superior officer of such entity. Grantor hereby ratifies and confirms any and all acts that Trustee, or his successor or successors in this trust shall do lawfully by virtue hereof. Grantor hereby agrees, on behalf of Grantor and of Grantor's heirs, legal representatives, successors and assigns, that the recitals contained in any deed or deeds or other instrument executed in due form by any Trustee or substitute trustee acting under the provisions of this Deed of Trust shall be prima facie evidence of the facts recited and that it shall not be necessary to prove in any court, otherwise than by such recitals, the existence of the facts essential to authorize the execution and delivery of such deed or deeds or other instrument and the pass-ing of title thereby and all prerequisites and requirements of any sale or sales shall be conclusively presumed to have been

performed and all persons subsequently dealing with the Mortgaged Property purported to be conveyed by such deed or deeds or other instrument including, without limitation, the purchaser or purchasers thereof, shall be fully protected in relying upon the truthfulness of such recitals.

(15)

The purchaser at any trustee's or foreclosure sale hereunder, may disaffirm any easement granted or rental or lease contract made in violation of any provision of this Deed of Trust and may take immediate posses-sion of the Mortgaged Property free from and despite the terms of such grant of easement and rental or lease contract.

(16)

The Beneficiary may bid and become the purchaser of the Mortgaged Property at any trustee's or foreclosure sale hereunder.

(17)

Subsequent to default hereunder or default pursuant to the other Credit Documents or any other instrument securing payment thereof, Grantor hereby authorizes the Beneficiary, if and whenever it shall desire, to demand and receive, in Grantor's right, all sums that may become due under any and each oil, gas, mineral or other lease, rental contract and easement contract pertaining to any portion of the Mortgaged Property and, when received, to apply the same on the indebtedness secured hereby. No demand for and no receipt or application of any such sum shall be deemed to minimize, subordinate or affect in any way the liens and rights hereunder of the Beneficiary or any rights of a pur-chaser of the Mortgaged Property at trustee's or foreclosure sale hereunder as against the person from whom such sum was demanded or received or his executors, administrators or assigns or anyone claiming under such lease, rental or easement contract.

(18)

Any part of the Mortgaged Property may be released by the Beneficiary without affecting the lien hereof against the remainder. The lien and rights hereby granted shall not affect or be affected by any other security taken for the same indebtedness or any part thereof. The taking of additional security or the extension, renewal or rearrangement of the same indebtedness or any part thereof, shall at no time release or impair the lien and rights granted hereby or affect the liability of any endorser or surety or improve the right of any junior lienholder; and this Deed of Trust, as well as any instrument given to secure any renewal or extension of the indebtedness secured hereby or any part thereof, shall be and remain a first and prior lien on all of the Mortgaged Property not expressly released until the said indebtedness is completely paid.

(19)

The invalidity or unenforceability in particular circumstances of any provision of this Deed of Trust shall not extend beyond such provision or such circumstances and no other provision of this Deed of Trust shall be affected thereby. It is the intention of the parties hereto to comply with applicable usury laws; accordingly, it is agreed that, notwithstanding any provisions to the contrary in the Credit Documents, or any instrument evidencing any indebtedness secured hereby, in this Deed of Trust or in any of the documents or instruments securing payment of said indebtedness or otherwise relating thereto, in no event shall the Credit Documents or such documents require the payment or permit the collection of interest in excess of the maximum amount permitted by such laws. If any such excess of interest is contracted for, charged or received under the Credit Documents or any instrument evidencing said indebtedness under this Deed of Trust or under the terms of any of the other documents securing payment of said indebtedness or otherwise relating thereto or in the event the maturity of any of said indebtedness is accelerated in whole or in part or in the event that all or part of the principal or interest of said indebtedness shall be prepaid so that, under any of such circumstances, the amount of interest contracted for, charged or received under the Credit Documents or any instruments evidencing said indebtedness under this Deed of Trust or under any of the instruments securing payment of said indebtedness or otherwise relating thereto on the amount of principal actually outstanding from time to time under the Credit Documents and other instruments evidencing said indebtedness shall exceed the maximum amount of interest permitted by applicable usury laws, then, in any such event, (a) the provisions of this paragraph shall govern and control, (b) neither Grantor nor any other person or entity now or hereafter liable for the payment of the amounts due under the Credit Documents or any instrument evidencing said indebtedness shall be obligated to pay the amount of such interest to the extent

that it is in excess of the maximum amount of interest permitted by applicable usury laws, (c) any such excess that may have been collected shall be either applied as a credit against the then unpaid principal amount of the Notes or refunded to Grantor, at the holder's option, and (d) the effective rate of interest shall be automatically reduced to the maximum non-usurious rate allowed under applicable usury laws as now or hereafter construed by the courts having jurisdiction thereof. It is further agreed that, without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under the Credit Documents or any instrument evidencing said indebtedness under this Deed of Trust or under such other documents that are made for the purpose of determining whether such rate exceeds the maximum non-usurious applicable rate, shall be made, to the extent permitted, by amortizing, prorating, allocating and spreading in equal parts during the period of the full stated term of the loans evidenced by the Notes or the instruments evidencing said indebtedness, all interest at any time contracted for, charged or received from Grantor or otherwise by the holder or holders hereof in connection with such loans.

(20)

Neither the Grantor, its heirs, executors, administrators or assigns, ever shall have or assert any right under any statute or rule of law pertaining to the marshaling of assets, the exemption of homestead, the admini-stration of estates of decedents or other matter whatever to defeat, reduce or affect the right of the Beneficiary under the terms of this Deed of Trust to a sale of the Mortgaged Property for the collection of said indebtedness (without any prior or different resort for collection) or the right of Beneficiary under the terms of this Deed of Trust to the payment of such indebtedness out of the proceeds of sale of the Mortgaged Property in preference to every other person and claimant whatever (only reasonable expenses as aforesaid being first deducted).

(21)

It is agreed that if default be made in the payment of any installment of the Notes, the holder of the indebtedness or any part thereof on which the payment is delinquent shall have the option to proceed with fore-closure in satisfaction of such item, either through the courts or by directing the Trustee or his successors in trust to proceed as if under a full foreclosure, conducting the sale as herein provided and without declaring the whole debt due and provided that, if sale is made because of default of an installment or a part of an installment, such sale may be made subject to the unmatured part of the Notes and debt secured by this Deed of Trust; and it is agreed that such sale, if so made, shall not in any manner affect the unmatured part of the debt secured by this Deed of Trust but, as to such unmatured part of this Deed of Trust, shall remain in full force and effect just as though no sale had been made under the provisions of this paragraph. And it is further agreed that several sales may be made hereunder without exhausting the right of sale for any unmatured part of the debt secured hereby, it being the purpose to pro-vide for a foreclosure and sale of the security for any matured portion of the debt secured hereby without exhausting the power to foreclose and to sell the security for any other part of the debt secured hereby, whether matured at the time or subsequently maturing. It is agreed that an assignee holding any installment or installments or part of any installment of the Notes secured hereby shall have the same powers as are hereby conferred on the holder of the indebtedness to proceed with foreclosure on a matured installment or installments and also to request the Trustee or successors in trust to sell the Mortgaged Property; but if an assignee forecloses or causes a sale to be made to satisfy any installment, part of an installment or installments, then such foreclosure or sale shall be made subject to the unmatured part of the Notes and the debt secured hereby owned by the holder of the indebtedness at the time or assigned subsequent to the assignment of the item to satisfy which the sale is being made.

(22)

It is expressly agreed that (a) no waiver of any default on the part of Grantor or breach of any of the provisions of this Deed of Trust shall be considered a waiver of any other or subsequent default or breach and no delay or omission in exercising or enforcing the rights and powers herein granted shall be construed as a waiver of such rights and powers and, likewise, no exercise or enforcement of any right or powers hereunder shall be held to exhaust such rights and powers and every such right and power may be exercised from time to time; (b) any failure by Beneficiary to insist upon the strict performance by Grantors of any of the terms and provisions hereof shall not be deemed to be a waiver of any of the terms and provisions hereof and Beneficiary, notwithstanding any such failure, shall have the right thereafter to insist upon the strict performance by Grantor of any and all of the terms and provisions of this Deed of Trust; (c) neither Grantor nor any other person now or hereafter obligated for the payment of the whole or any part of said indebtedness shall be relieved of such obligation by reason of the failure of Beneficiary or Trustee to comply with any request of Grantor or of any other person so obligated to take action to foreclose this Deed of Trust or otherwise enforce any of the provisions of this Deed of Trust or of any obligations secured by this Deed of Trust or by reason of the release, regardless of consideration, of the whole or any part of the security held for said indebtedness or by reason of the subordination in whole or in part by Beneficiary of the lien, security interest or rights evidenced hereby or by reason of any agreement or stipulation which any subsequent owner or owners of the Mortgaged Property extending the time of payment or modifying the terms of said indebted-ness or this Deed of Trust without first having obtained the consent of Grantor or such other person and, in the latter event, Grantor and all such other persons shall continue liable to make such payments according to the terms of any such agreement of extension or modification unless expressly released and discharged in writing by Beneficiary; (d) regardless of consideration and without the necessity for any notice to or consent by the holder of any subordinate lien or security interest on the

Mortgaged Property, Beneficiary may release the obligation of anyone at any time liable for any of said indebtedness or any part of the security held for said indebtedness and may extend the time of payment or otherwise modify the terms of said indebtedness and/or this Deed of Trust without, as to the security or the remainder thereof, in anywise impairing or affecting the lien or security interest of this Deed of Trust or the priority of such lien or security interest as security for the payment of said indebtedness as it may be so extended or modified over any subordinate lien or security interest; (e) the holder of any subordinate lien or security interest shall have no right to terminate any lease affecting the Mortgaged Property, whether or not such lease be subordinate to this Deed of Trust; and (f) Beneficiary may resort, for the payment of said indebtedness, to any secu-rity therefor held by Beneficiary in such order and manner as Beneficiary may elect.

(23)

In the event that there be a trustee's sale hereunder and if, at the time of such sale, Grantor, its heirs, executors, administrators or assigns, be occupying the premises so sold, each and all shall immediately become the tenant of the purchaser at such sale, which tenancy shall be a tenancy from day to day, terminable at the will of either tenant or landlord, at a reasonable rental per day, based upon the value of the Mortgaged Property, such rental to be due daily to the purchaser. An action of forcible detainer shall lie if the tenant holds over after a demand in writing for possession of the Mortgaged Property; and this Deed of Trust and the trustee's deed shall constitute a lease and agreement under which the tenant's possession, each and all, arose and continued.

(24)

In the event any portion of said indebtedness is not, for any reason whatsoever, secured by this Deed of Trust on the Mortgaged Property, the full amount of all payments made on said indebtedness shall first be applied to such unsecured portion of said indebtedness until the same has been fully paid.

(25)

It is agreed that the lien hereby created shall take precedence over and be a prior lien to any other lien of any character, whether vendor's, materialmen's or mechanics' lien hereafter created on the Mortgaged Property and, in the event the proceeds of the Notes are used to pay off and satisfy any liens heretofore existing on the Mortgaged Property, then Beneficiary is and shall be subrogated to all of the rights, liens and remedies of the holders of the indebtedness so paid.

(26)

The covenants herein contained shall bind and the benefits and advantages shall inure to the respective heirs, executors, administrators, successors and assigns of the parties hereto and to any substitute trustee. Whenever used, the singular number shall include the plural, the plural the singular, and the use of any gender shall be applicable to all genders. The term "Beneficiary" shall also include any lawful owner, holder or pledgee of any indebtedness secured hereby.

(27)

Without limiting any of the provisions of this Deed of Trust, the Grantor, as Debtor and referred to in this Paragraph as "Debtor," expressly:

(a)

Grant unto the holder of all indebtedness described herein, as Secured Party and referred to in this Paragraph as "Secured Party," a security interest in all of the properties herein-above described (including both those now and those hereafter existing) to the full extent that same may be subject to Chapter 9 of the Texas Business and Commerce Code as now adopted and existing and as it may hereinafter be amended or succeeded (hereinafter called "Uniform Commercial Code").

(b)

Agree that, in addition to any other remedies granted in this instrument to the Secured Party or Trustee, the Secured Party may, in the event of any default, proceed under the Uniform Commercial Code as to all or any part of the personal property (tangible or intangible) and fixtures included in the properties described herein or located on or affixed to the Mortgaged Property (such portion of the properties being herein referred to as "Collateral") and shall have and may exercise, with respect to the Collateral, all the rights, remedies, and powers of a Secured Party under the Uniform Commercial Code including, without limitation, the right and power to sell at public or private sale or sales or otherwise dispose of, lease or utilize the Collateral and any part or parts thereof in any manner authorized or permitted under said Uniform Commercial Code after default by a debtor and to apply the proceeds thereof toward payment of any costs and expenses and attorney's fees and legal expenses thereby incurred by Secured Party and toward payment of the Debtors' obligations including the Credit Documents and all other indebtedness described in this instrument in such order or manner as Secured Party may elect. Among the rights of Secured Party in the event of default and,

without limitation, Secured Party shall have the right to take possession of the Collateral and to enter upon any premises where same may be situated for such purpose without being deemed guilty of trespass and without liability for damages thereby occasioned and to take any action deemed necessary or appropriate or desirable by Secured Party, at its option and in its discretion, to repair, refurbish or otherwise prepare the Collateral for sale, lease or other use or disposition as herein authorized. To the extent permitted by law, Debtor expressly waives any notice of sale or other disposition of the Collateral and any other rights or remedies of a debtor or for-malities prescribed by law relative to sale or disposition of the Collateral or exercise of any other right or remedy of Secured Party existing after default hereunder; and to the extent any such notice is required and cannot be waived, Debtor agrees that if such notice is mailed, postage prepaid, to the Debtor at the address shown herein at least five (5) days before the time of the sale or disposition, such notice shall be deemed reasonable and shall fully satisfy any requirement for giving of said notice.

(c)

Grant to the Secured Party, after default hereunder, the right, at its option, to transfer at any time to itself or to its nominee the Collateral or any part thereof and to receive the monies, income, proceeds or benefits attributable or accruing thereto and to hold the same as security for the Debtor's obligations or to apply it on the principal and interest or other amounts owing on any of the Debtor's obligations, whether or not then due, in such order or manner as the Secured Party may elect. All rights or marshaling of assets of Debtor, including any such right with respect to the Collateral, are hereby waived.

(d)

Covenant, stipulate and agree that all recitals in any instrument of assignment or any other instrument executed by Secured Party incident to sale, transfer, assignment, lease or other disposition or utilization of the Collateral or any part thereof hereunder shall be full proof of the matters stated therein and no other proof shall be requisite to establish full legal propriety of the sale or other action taken by Secured Party or of any fact, condition or thing incident thereto and all prerequisites of such sale or other action or of any fact, condition or thing incident thereto shall be presumed conclusively to have been per-formed or to have occurred.

(e)

Covenant and agree that Secured Party may require Debtors, after default hereunder, to assemble the Collateral and make it available to Secured Party at a place to be designated by Secured Party that is reasonably convenient to both parties. All expenses of retaking, holding, preparing for sale, lease or other use or disposition, selling, leasing or otherwise using or disposing of the Collateral and the like which are incurred or paid by Secured Party as authorized or permitted hereunder, including also all attorney's fees, legal expenses and costs, shall be added to the Debtor's obligations and the Debtor shall be liable therefor.

(f)

Covenant and agrees that the Secured Party may, at its election, at any time after delivery of this instrument, sign one or more copies of this instrument in order that such copies may be used as a Financing Statement under the Uniform Commercial Code. Such sig-nature by the Secured Party may be placed between the last sentence of the instrument and the Debtor's acknowledgment or may follow the Debtor's acknowledgment. The Secured Party's signature need not be acknowledged and is not necessary to the effec-tiveness of this instrument as a deed of trust, mortgage, assignment, pledge or security agreement.

Except for the security interest granted hereby in the Collateral, Debtor is the owner and holder of the Collateral free of any adverse claim, security interest or encumbrance and Debtor will defend the Collateral against all claims and demands of any person at any time claiming the same or any interest therein. Debtor has not here-tofore signed any financing statement covering the Collateral and no such financing statement signed by Debtor is now on file in any public office except those statements true and correct copies of which have been delivered to the Secured Party. So long as any amount remains unpaid on any indebtednesses described in this Deed of Trust, Debtor will not execute and there will not be filed in any public office such financing statement or statements affecting the Collateral other than financing statements in favor of Secured Party hereunder unless the prior written specific consent

and approval of Secured Party shall have first been obtained. Debtor authorizes Secured Party to file, in jurisdictions where this authorization will be given effect, a financing statement signed only by Secured Party covering the Collateral and, at the request of Secured Party, Debtor will join Secured Party in executing one or more financing statements pursuant to the Uniform Commercial Code, in form satisfactory to Secured Party, and will pay the cost of filing the same or filing or recording this instrument as a financing statement in all public offices at any time and from time to time whenever filing or recording of any financing statement or of this instrument is deemed by Secured Party to be necessary or desirable.

(28)

Portions of the Mortgaged Property are goods which are or are to become fixtures relating to the property described in Exhibit "A" and the Grantor herein expressly covenants and agrees that the filing of this Deed of Trust in the real estate records of the county where the Mortgaged Properties are located shall also operate from time of filing therein as a financing statement filed as a fixture filing in accordance with Section 9.502(c) of the Uniform Commercial Code - Secured Transaction of the State of Texas.

(29)

Grantor will pay all fees or costs for appraisals that the Beneficiary may reasonably require from time to time, but in no event more than one (1) appraisal annually. In addition, Grantor will pay all recording fees, taxes, abstract fees, attorneys' fees and all other costs and expenses of every character from time to time incurred in connection with the making, closing and servicing of the loan evidenced by the Notes, or any renewal, modification, rearrangement or extension thereof and will pay all reasonable fees and charges made by the Trustee for services performed hereunder and will reimburse Beneficiary and the Trustee for all expenses incurred by them, respectively, and will indemnify and hold harmless Beneficiary and the Trustee from and against all claims, demands, liabilities and causes of action asserted against either of them on account of any act performed or omitted to be performed hereunder or on account of any transaction arising out of or in any way connected with the Mortgaged Property or this Deed of Trust, save and except for their willful misconduct. In the event that Beneficiary should pay for expenses incurred in way of attorneys' fees in connection with title examination and legal matters and/or appraisal fees or costs connected with the making, closing or servicing the Credit Documents or any renewal, modification, rearrangement or extension thereof, or pay any recording or filing fee or fees incident to recording instruments, title insurance premiums and title insurance endorsement fees, Grantor shall reimburse the Beneficiary for all such sums upon demand. Any such sums shall become part of the indebtedness secured by this Deed of Trust and shall bear interest from the date incurred by Beneficiary at the rate provided in the Credit Documents.

(30)

The term "Hazardous Materials" shall mean (a) any "hazardous waste" as defined by the Resource Conservation and Recovery Act of 1976 (42 U.S.C. Section 6901 et seq.), as amended from time to time, and regu-lations promulgated thereunder; (b) any "hazardous substance" as defined by the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (42 U.S.C. Section 9601 et seq.), as amended from time to time, and regulations promulgated thereunder; (c) asbestos; (d) polychlorinated biphenyls; (e) underground storage tanks, whether empty, filled or partially filled with any substances (f) any substance the presence of which on the Mortgaged Property is prohibited by any Governmental Requirements; and (g) any other substance which by any Governmental Requirements requires special handling or notification of any federal, state or local governmental entity in its collection, storage, treatment or disposal. The term "Governmental Requirements" shall mean all laws, ordinances, rules and regulation of the United States, the state, the county, the city or any other political subdivision in which the Mortgaged Property is located, and any other political subdivision, agency or instrumentality exercising jurisdiction over Grantor, any guarantor of the Notes, or the Mortgaged Property.

The term "Hazardous Materials Contamination" shall mean the contamination (whether presently existing or hereafter occurring) of the Mortgaged Property, any improvements, facilities, soil, groundwater, air or other elements on or off the Mortgaged Property by Hazardous Materials, or the contamination of the buildings, facilities, soil, groundwater, air or other elements on or of any other property as a result of Hazardous Materials at any time (whether before or after the date hereof) emanating from the Mortgaged Property.

Grantor represents and warrants to Beneficiary that:

(a)

To the best of Grantor's knowledge no Hazardous Materials are located on the Mortgaged Property or have been released into the environment, or deposited, discharged, placed or disposed of at, on, under or near the Mortgaged Property. No portion of the

Mortgaged Property is being used or, to the knowledge of Grantor, has been used at any previous time for the disposal, storage, treatment, processing or other handling of Hazardous Materials nor is the Mortgaged Property affected by any Hazardous Materials Contamination.

(b)

To the best of Grantor's knowledge, no Hazardous Materials are located in the vicinity of the Mortgaged Property.

(c)

To the best of Grantor's knowledge no polychlorinated biphenyls have been released on the Mortgaged Property, from electrical transformers, cooling oils, or any other device or form.

(d)

To the best of Grantor's knowledge, no investigation, administrative order, consent order and agreement, litigation or settle-ment with respect to Hazardous Materials or Hazardous Materials Contamination is pro-posed, threatened, anticipated or in existence with respect to the Mortgaged Property. To the best of Grantor's knowledge, the Mortgaged Property and its existing and prior uses comply and at all times have complied with any applicable Governmental Requirements relating to environmental matters or Hazardous Materials. To the best of Grantor's knowledge, there is no condition on the Mortgaged Property which is in violation of any applicable Governmental Requirements relating to Hazardous Materials, and Grantor has received no communication from or on behalf of any Governmental Authority that any such condition exists. The Mortgaged Property is not currently on and, to Grantor's knowledge after diligent investigation and inquiry, has never been on any federal or state "Superfund" or "Superlien" list.

(e)

All representations and warranties contained in this Section shall survive the consumma-tion of the transactions contemplated hereby.

Grantor covenants as follows:

(a)

Grantor agrees to (i) give notice to Beneficiary immediately upon Grantor's acquiring knowledge of the presence of any Hazardous Materials on the Mortgaged Property or of any Hazardous Materials Contamination with a full description thereof; (ii) promptly, at Grantor's sole cost and expense, complies with any Governmental Requirements requiring the removal, treatment or disposal of such Hazardous Materials or Hazardous Materials Contamination and provide Beneficiary with satisfactory evidence of such compliance; and (iii) provides Beneficiary, within thirty (30) days after demand by Beneficiary, with a bond, letter of credit or similar financial assurance evidencing to Beneficiary's satisfaction that the necessary funds are available to pay the cost of removing, treating and disposing of such Hazardous Materials or Hazardous Materials Contamination and discharging any assessments which may be established on the Mortgaged Property as a result thereof.

(b)

Grantor shall not cause or suffer any liens to be recorded against the Mortgaged Property as a consequence of, or in any way related to, the presence, remediation or disposal of Hazardous Material in or about the Mortgaged Property, including any state, federal or local so-called "Superfund" lien relating to such matters.

SUBORDINATION AGREEMENT

THE STATE OF TEXAS

KNOW ALL PERSONS BY THESE PRESENTS:

COUNTY OF ▇▇▇▇▇▇

The undersigned (hereinafter called "Subordinated Creditor") for value received, the receipt and sufficiency of which is hereby acknowledged, and to induce Southwest Bank of Texas, N.A., a national banking association (hereinafter called "Lender"), at its option at any time or from time to time to loan monies with or without security to or for the account of Phyto-Source, L.P., a Texas limited partnership (hereinafter called "Borrower"), and at the special insistence and request of Lender, Subordinated Creditor hereby agrees with Lender as follows:

The payment of and any liens or security interests securing payment of any and all Subordinated Debt is expressly subordinated to the extent and in the manner set forth in paragraphs 2 through 6, inclusive, hereof to Senior Indebtedness (defined below) and the liens and security interests securing Senior Indebtedness. The term "Subordinated Debt" as used in this Subordination Agreement shall mean and include any and all indebtedness, liabilities and obligations of Borrower to the Subordinated Creditor, absolute or contingent, direct or indirect, joint, several or independent, now outstanding or owing or which may hereafter be existing or incurred, arising by operation of law or otherwise, due or to become due, or held or to be held by the Subordinated Creditor, whether created directly or acquired by assignment, as a participation, conditionally, as collateral security from another or otherwise, including indebtedness, obligations and liabilities of Borrower to Subordinated Creditor as a member of any partnership, syndicate, association or other group, and whether incurred by Borrower as principal, surety, endorser, guarantor, accommodation party or otherwise, including, without limiting the generality of the foregoing, all indebtedness, liabilities and obligations of Borrower to the Subordinated Creditor arising out of (a) that certain Loan Agreement dated July 17, 2001 evidencing a loan from Subordinated Creditor to Borrower in the principal amount of $4,000,000 between Subordinated Creditor and Borrower, as evidenced by (i) that certain Phyto-Source, L.P. Promissory Note dated July 17, 2001 (the "Subordinated Note"), (ii) that certain Deed of Trust, Security Agreement and Financing Statement dated July 17, 2001, filed for record under ▇▇▇▇▇▇ County Clerk File No. V193678, securing debt in the amount of $4,000,000.00, payable to Subordinated Creditor, and (iii) that certain Financing Statement filed with the Secretary of State of the State of Texas on July 26, 2001 at entry 01-139313 and pursuant to that certain Amended and Restated Formation and Contribution Agreement executed on July 17, 2001 (the "Formation Agreement") and (b) any and all accounts payable due from Borrower to Subordinated Creditor ("Accounts Payable"), including amounts payable pursuant to that certain ▇▇▇▇ of Sale dated July 17, 2001 and that certain Formation Agreement, except that, during the term of this Subordination Agreement, the aggregate amount of $1,000,000 in Accounts Payable will not be subject to the terms of this Subordination Agreement and may be paid in accordance with the terms of the Formation Agreement. The agreements and other documents evidencing the Subordinated Debt being the "Subordinated Loan Documents."

The term "Senior Indebtedness" as used in this Subordination Agreement shall mean and include any and all indebtedness, liabilities and obligations of Borrower to Lender absolute or contingent, direct or indirect, joint, several or independent, now outstanding or owing or which may hereafter be existing or incurred, arising by operation of law or otherwise, due or to become due, or held or to be held by Lender whether created directly or acquired by assignment, as a participation, conditionally, as collateral security from another or otherwise, including indebtedness, obligations and liabilities of Borrower to Lender as a member of any partnership, syndicate, association or other group, and whether incurred by Borrower as principal, surety, endorser, guarantor, accommodation party or otherwise and including, without limitation, the Obligation, as that term is defined in the Credit Agreement between Borrower and Lender of even date herewith (the "Credit Agreement"). Capitalized terms used herein and not defined shall have the meaning ascribed to such terms in the Credit Agreement.

During such time as any Senior Indebtedness remains unpaid, Subordinated Creditor will not ask for, demand, ▇▇▇ for, take, receive or accept from the Borrower, by set off or in any other manner, any payment or distribution on account of the Subordinated Debt, nor present any instrument evidencing the Subordinated Debt for payment (other than such presentment as may be necessary to prevent discharge of other liable parties on such instrument), provided, however, nothing contained herein shall prevent Subordinated Creditor from receiving interest payments under the Subordinated Note subject to paragraph 3 hereof. Subordinated Creditor hereby agrees that any and all liens and security interests related to the Subordinated Debt are subordinate in priority to the liens and security interests related to the Senior Indebtedness.

If for any reason any of the Senior Indebtedness is not paid when due or is not paid on or before the maturity thereof, or if there shall occur and be continuing any event which with the giving of notice or lapse of time or both would constitute a default or event of default under any instrument or agreement now or hereafter executed evidencing, in connection with, as security for or providing for the issuance of any of the Senior Indebtedness, then, unless and until such event of default or default shall have been cured, or unless and until the Senior Indebtedness shall be paid in full, the Subordinated Creditor will not ask for, ▇▇▇ for, take, demand, receive or accept from Borrower, by set off or in any other manner, any payment or distribution on account of the Subordinated Debt nor present any instrument evidencing the Subordinated Debt for payment (other than such presentment as may be necessary to prevent discharge of other liable parties on such instrument).

The Subordinated Creditor will not ask for, demand, ▇▇▇ for, take, receive or accept from Borrower, by set off or in any other manner, any payment or distribution on account of the Subordinated Debt, if the making of such payment would constitute, or would result in the occurrence of, a violation of the provisions of any instrument or agreement evidencing, in connection with, as security for or providing for the issuance of any Senior Indebtedness or would result in the occurrence of any event which with the giving of notice or lapse of time or both would constitute an event of default or default under the provisions of any such instrument or agreement.

In the event the Subordinated Creditor shall receive any payment or distribution on account of the Subordinated Debt which Subordinated Creditor is not entitled to receive under the provisions of the foregoing paragraphs 2, 3, or 4. Subordinated Creditor will hold any amount so received in trust for Lender and will forthwith turn over such payment to Lender in the form received by Subordinated Creditor (together with any necessary endorsement) to be applied on the Senior Indebtedness.

The Subordinated Creditor will not commence any action or proceeding against Borrower to recover all or any part of the Subordinated Debt or join with any other creditor, unless Lender shall also join, in bringing any proceedings against Borrower under any bankruptcy, reorganization, readjustment of debt, arrangement of debt, receivership, liquidation or insolvency law or statute of the federal or any state government unless and until all Senior Indebtedness shall have been paid in full.

In the event of any receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization or arrangement with creditors, adjustment of debt, whether or not pursuant to bankruptcy laws, the sale of all or substantially all of the assets, dissolution, liquidation, or any other marshaling of the assets and liabilities of Borrower, the Subordinated Creditor will at Lender's request file any claim, proof of claim, proof of interest or other instrument of similar character necessary to enforce the obligations of Borrower in respect of the Subordinated Debt and will hold in trust for Lender and pay over to Lender, in the form received (together with any necessary endorsement), to be applied on the Senior Indebtedness, any and all monies, dividends or other assets received in any such proceedings on account of the Subordinated Debt unless and until the Senior Indebtedness shall be paid in full. In the event that the Subordinated Creditor shall fail to take any such action requested by Lender, Lender, may, as attorney in fact for the Subordinated Creditor take such action on behalf of the Subordinated Creditor, and the Subordinated Creditor hereby appoints Lender as attorney in fact for the Subordinated Creditor to demand, ▇▇▇ for, collect and receive any and all such monies, dividends or other assets and give acquittance therefor and to file any claim, proof of claim, proof of interest or other instrument of similar character and to take such other proceedings in Lender's own name or in the name of the Subordinated Creditor as Lender may deem necessary or advisable for the enforcement of this Subordination Agreement; and the Subordinated Creditor will execute and deliver to Lender such other and further powers of attorney or other instruments as Lender may request in order to accomplish the foregoing.

(a)

Lender shall have the exclusive right, without the consent of Subordinated Creditor, (i) to take action with respect to, consent to the release of the liens of the Lender, or sell or otherwise dispose of, the Collateral in accordance with the Credit Agreement and the other Loan Documents or as permitted by applicable law, (ii) to enforce and realize upon the liens held by Lender, in accordance with the Loan Documents or as permitted by applicable law, (iii) to enforce all rights and privileges accruing to Lender by reason of, and in accordance with, the Loan Documents, and (iv) to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Subordination Agreement or the Loan Documents.

(b)

Notwithstanding the occurrence of a default under the Subordinated Loan Documents or any other event, condition or circumstance whatsoever, prior to the full and final payment of the Senior Indebtedness, Subordinated Creditor shall not (i) take any action on its behalf of the type which Lender is entitled to take under Section 8(a), (ii) in any manner interfere with the liens or rights held by Senior Lender, or (iii) take any action with respect to any of the Collateral.

Lender may, at any time, and from time to time, without the consent of or notice to the Subordinated Creditor, without incurring responsibility to the Subordinated Creditor, without impairing or releasing any of Lender's rights or any of the obligations of the Subordinated Creditor under this Subordination Agreement:

(a)

Change the amount, manner, place or terms of payment, or change or extend for any period the time of payment of, or renew, rearrange or otherwise modify or alter, the Senior Indebtedness or any instrument or agreement now or hereafter executed evidencing, in connection with, as security for or providing for the issuance of any of the Senior Indebtedness in any manner, or enter into or amend in any manner any other agreement relating to the Senior Indebtedness (including provisions restricting or further restricting payments of the Subordinated Debt);

(b)

Sell, exchange, release or otherwise deal with all or any part of any property by whomsoever at any time pledged or mortgaged to secure, howsoever securing, the Senior Indebtedness;

(c)

Release anyone liable in any manner for payment or collection of the Senior Indebtedness;

(d)

Exercise or refrain from exercising any rights against Borrower or others (including the Subordinated Creditor); and

(e)

Apply any sums received by Lender, by whomsoever paid and however realized, to payment of the Senior Indebtedness in such a manner as Lender, in its sole discretion, may deem appropriate.

10.

The Subordinated Creditor will (i) cause all Subordinated Debt to be evidenced by a note, debenture or other instrument evidencing the Subordinated Debt, (ii) at Lender's request promptly surrender or cause to be surrendered any such note, debenture, or instrument evidencing the Subordinated Debt so that a statement or legend may be entered thereon to the effect that such note, debenture, or other instrument is subordinated to the Senior Indebtedness in favor of Lender in the manner and to the extent set forth in this Subordination Agreement, (iii) ▇▇▇▇ the books of Subordinated Creditor to show that the Subordinated Debt is subordinated to the Senior Indebtedness in the manner and to the extent set forth in this Subordination Agreement, and (iv) cause all financial statements of the Subordinated Creditor hereafter prepared for delivery to any person to make specific reference to the provisions of this Subordination Agreement.

11.

The Subordinated Creditor agrees to execute any and all other instruments necessary as required by the Lender to subordinate the Subordinated Debt to the Senior Indebtedness as herein provided.

12.

Subordinated Creditor will not assign or transfer to others any claim the Subordinated Creditor has or may have against Borrower as long as any of the Senior Indebtedness remains outstanding, unless such assignment or transfer is expressly made subject to this Subordination Agreement.

13.

The Subordinated Creditor represents and warrants that (i) neither the execution nor delivery of this Subordination Agreement nor fulfillment of or compliance with the terms and provisions hereof will conflict with, or result in a breach of the terms, conditions or provisions of, or constitute a default under, any agreement or instrument (including, without limitation, articles of incorporation or bylaws) to which Subordinated Creditor is now subject, and (ii) none of the Subordinated Debt is or will be subordinated to any other indebtedness of Borrower other than the Senior Indebtedness unless otherwise agreed by Lender.

14.

Notice of acceptance of this Subordination Agreement is waived, acceptance on the part of Lender being conclusively presumed by its request for this Subordination Agreement and delivery of the same to it.

15.

This Subordination Agreement may be assigned by Lender in connection with any assignment or transfer of the Senior Indebtedness.

16.

THIS SUBORDINATION AGREEMENT SHALL BE CONSTRUED UNDER AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

EXECUTED AND EFFECTIVE on the 1^st day of August, 2003.
