Grantor shall not guarantee, endorse or otherwise become contingently liable in connection with any obligations of any other person or entity, and shall not create or incur any additional liability, whether contingent or non-contingent, with respect to either Grantor or the Mortgaged Property, except as specifically allowed or contemplated pursuant to the Loan Documents.

ARTICLE VII

REMEDIES

7.1 Beneficiary’s Remedies Upon Default. Upon the occurrence of an Event of Default or any event or circumstance which, with the lapse of time, or the giving of notice, or both, would constitute an Event of Default, Beneficiary may, at Beneficiary’s option, and by or through Trustee, by Beneficiary itself or otherwise, do any one or more of the following:

(a) Right to Perform Grantor’s Covenants. If Grantor has failed to keep or perform any covenant whatsoever contained in this Deed of Trust or the other Loan Documents, Beneficiary may, but shall not be obligated to any person to do so, perform or attempt to perform said covenant, and any payment made or expense incurred in the performance or attempted performance of any such covenant shall be and become a part of the Indebtedness.

(b) Right of Entry. Beneficiary may, prior or subsequent to the institution of any foreclosure proceedings, enter upon the Mortgaged Property, or any part thereof, and take exclusive possession of the Mortgaged Property and copies of all books, records, and accounts relating thereto and to exercise without interference from Grantor any and all rights which Grantor has with respect to the management, possession, operation, protection, or preservation of the Mortgaged Property.

(c) Right to Accelerate. Beneficiary may, without notice, demand, presentment, notice of nonpayment or nonperformance, protest, notice of protest, notice of intent to accelerate, notice of acceleration, or any other notice or any other action, all of which are hereby waived by Grantor and all other parties obligated in any manner whatsoever on the Indebtedness, declare the entire unpaid balance of the Indebtedness immediately due and payable, and upon such declaration, the entire unpaid balance of the Indebtedness shall be immediately due and payable. The failure to exercise any remedy available to the Beneficiary shall not be deemed to be a waiver of any rights or remedies of the Beneficiary under the Loan Documents, at law or in equity.

(d) Foreclosure-Power of Sale. Beneficiary may request Trustee to proceed with foreclosure under the power of sale which is hereby conferred, such foreclosure to be accomplished in accordance with the following provisions:

14

(1) Public Sale. Trustee is hereby authorized and empowered, and it shall be Trustee’s special duty, upon such request of Beneficiary, to sell the Mortgaged Property, or any part thereof, at public auction to the highest bidder for cash, with or without having taken possession of same. Any such sale of the Mortgaged Property (including notice thereof) shall comply with the applicable requirements, at the time of the sale, of Section 51.002 of the Texas Property Code or, if and to the extent such statute is not then in force, with the applicable requirements, at the time of the sale, of the successor statute or statutes, if any, governing sales of Texas real property under powers of sale conferred by deeds of trust. If there is no statute in force at the time of the sale governing sales of Texas real property under powers of sale conferred by deeds of trust, such sale shall comply with applicable law, at the time of the sale, governing sales of Texas real property under powers of sale conferred by deeds of trust.

(2) Right to Require Proof of Financial Ability and/or Cash Bid. At any time during the bidding, the Trustee may require a bidding party (A) to disclose its full name, state and city of residence, occupation, and specific business office location, and the name and address of the principal the bidding party is representing (if applicable), and (B) to demonstrate reasonable evidence of the bidding party’s financial ability (or, if applicable, the financial ability of the principal of such bidding party), as a condition to the bidding party submitting bids at the foreclosure sale. If any such bidding party (the “Questioned Bidder”) declines to comply with the Trustee’s requirement in this regard, or if such Questioned Bidder does respond but the Trustee, in Trustee’s sole and absolute discretion, deems the information or the evidence of the financial ability of the Questioned Bidder (or, if applicable, the principal of such bidding party) to be inadequate, then the Trustee may continue the bidding with reservation; and in such event (1) the Trustee shall be authorized to caution the Questioned Bidder concerning the legal obligations to be incurred in submitting bids, and (2) if the Questioned Bidder is not the highest bidder at the sale, or if having been the highest bidder the Questioned Bidder fails to deliver the cash purchase price payment promptly to the Trustee, all bids by the Questioned Bidder shall be null and void. The Trustee may, in Trustee’s sole and absolute discretion, determine that a credit bid may be in the best interest of the Grantor and Beneficiary, and elect to sell the Mortgaged Property for credit or for a combination of cash and credit; provided, however, that the Trustee shall have no obligation to accept any bid except an all cash bid. In the event the Trustee requires a cash bid and cash is not delivered within a reasonable time after conclusion of the bidding process, as specified by the Trustee, but in no event later than 3:45 p.m. local time on the day of sale, then said contingent sale shall be null and void, the bidding process may be recommenced, and any subsequent bids or sale shall be made as if no prior bids were made or accepted.

(3) Sale Subject to Unmatured Indebtedness. In addition to the rights and powers of sale granted under the preceding provisions of this subsection, if default is made in the payment of any installment of the Indebtedness, Beneficiary may, at Beneficiary’s option, at once or at any time thereafter while any matured

15

installment remains unpaid, without declaring the entire Indebtedness to be due and payable, orally or in writing direct Trustee to enforce this trust and to sell the Mortgaged Property subject to such unmatured Indebtedness and to the rights, powers, liens, security interests, and assignments securing or providing recourse for payment of such unmatured Indebtedness, in the same manner, all as provided in the preceding provisions of this subsection. Sales made without maturing the Indebtedness may be made hereunder whenever there is a default in the payment of any installment of the Indebtedness, without exhausting the power of sale granted hereby, and without affecting in any way the power of sale granted under this subsection, the unmatured balance of the Indebtedness or the rights, powers, liens, security interests, and assignments securing or providing recourse for payment of the Indebtedness.

(4) Partial Foreclosure. Sale of a part of the Mortgaged Property shall not exhaust the power of sale, but sales may be made from time to time until the Indebtedness is paid and the Obligations are performed and discharged in full. It is intended by each of the foregoing provisions of this subsection that Trustee may, after any request or direction by Beneficiary, sell not only the Land and the Improvements, but also the Fixtures and Personalty and other interests constituting a part of the Mortgaged Property or any part thereof, along with the Land and the Improvements or any part thereof, as a unit and as a part of a single sale, or may sell at any time or from time to time any part or parts of the Mortgaged Property separately from the remainder of the Mortgaged Property. It shall not be necessary to have present or to exhibit at any sale any of the Mortgaged Property.

(5) Trustee’s Deeds. After any sale under this subsection, Trustee shall make good and sufficient deeds, assignments, and other conveyances to the purchaser or purchasers thereunder in the name of Grantor, conveying the Mortgaged Property or any part thereof so sold to the purchaser or purchasers with general warranty of title by Grantor. It is agreed that in any deeds, assignments or other conveyances given by Trustee, any and all statements of fact or other recitals therein made as to the identity of Beneficiary, the occurrence or existence of any Event of Default, the notice of intention to accelerate, or acceleration of, the maturity of the Indebtedness, the request to sell, notice of sale, time, place, terms and manner of sale, and receipt, distribution, and application of the money realized therefrom, the due and proper appointment of a substitute trustee, and without being limited by the foregoing, any other act or thing having been duly done by or on behalf of Beneficiary or by or on behalf of Trustee, shall be taken by all courts of law and equity as prima facie evidence that such statements or recitals state true, correct, and complete facts and are without further question to be so accepted, and Grantor does hereby ratify and confirm any and all acts that Trustee may lawfully do in the premises by virtue hereof.

(e) Beneficiary’s Judicial Remedies. Beneficiary, or Trustee, upon written request of Beneficiary, may proceed by suit or suits, at law or in equity, to enforce the payment of the Indebtedness and the performance and discharge of the Obligations in

16

accordance with the terms hereof, of the Notes, and the other Loan Documents, to foreclose the liens and security interests of this Deed of Trust as against all or any part of the Mortgaged Property, and to have all or any part of the Mortgaged Property sold under the judgment or decree of a court of competent jurisdiction. This remedy shall be cumulative of any other nonjudicial remedies available to the Beneficiary with respect to the Loan Documents. Proceeding with a request or receiving a judgment for legal relief shall not be or be deemed to be an election of remedies or bar any available nonjudicial remedy of the Beneficiary.

(f) Beneficiary’s Right to Appointment of Receiver. Beneficiary, as a matter of right and without regard to the sufficiency of the security for repayment of the Indebtedness and performance and discharge of the Obligations, without notice to Grantor and without any showing of insolvency, fraud, or mismanagement on the part of Grantor, and without the necessity of filing any judicial or other proceeding other than the proceeding for appointment of a receiver, shall be entitled to the appointment of a receiver or receivers of the Mortgaged Property or any part thereof, and of the Rents, and Grantor hereby irrevocably consents to the appointment of a receiver or receivers. Any receiver appointed pursuant to the provisions of this subsection shall have the usual powers and duties of receivers in such matters.

(g) Beneficiary’s Uniform Commercial Code Remedies. The Beneficiary may exercise its rights of enforcement with respect to Fixtures and Personalty under the Code and as permitted in the Credit Agreement.

(h) Rights Relating to Leases and Rents. Grantor has, pursuant to Article IX of this Deed of Trust, assigned, as collateral, to Beneficiary all Rents under each of the Leases covering all or any portion of the Mortgaged Property. Beneficiary, or Trustee on Beneficiary’s behalf, may at any time, and without notice, either in person, by agent, or by receiver to be appointed by a court, enter and take possession of the Mortgaged Property or any part thereof, and in its own name, sue for or otherwise collect the Rents. Grantor hereby agrees with Beneficiary, upon notice from Trustee or Beneficiary to Grantor of the occurrence of an Event of Default, terminate the limited license granted to Grantor in Section 9.2 hereof, and thereafter direct the lessees under the Leases to pay direct to Beneficiary the Rents due and to become due under the Leases and attorn in respect of all other obligations thereunder direct to Beneficiary, or Trustee on Beneficiary’s behalf, without any obligation on their part to determine whether an Event of Default does in fact exist or has in fact occurred. All Rents collected by Beneficiary, or Trustee acting on Beneficiary’s behalf, shall be applied as provided for in Section 7.4 of this Deed of Trust; provided, however, that if the costs, expenses, and attorneys’ fees shall exceed the amount of Rents collected, the excess shall be added to the Indebtedness, shall bear interest at the Default Rate, and shall be immediately due and payable. The entering upon and taking possession of the Mortgaged Property, the collection of Rents, and the application thereof as aforesaid shall not cure or waive any Event of Default or notice of default, if any, hereunder nor invalidate any act done pursuant to such notice, except to the extent any such default is fully cured. In addition, from time to time Beneficiary may elect, and notice hereby is given to each lessee under any Lease, to subordinate the lien of this Deed of Trust to any Lease by unilaterally executing and

17

recording an instrument of subordination, and upon such election the lien of this Deed of Trust shall be subordinate to the Lease identified in such instrument of subordination; provided, however, in each instance such subordination will not affect or be applicable to, and expressly excludes any lien, charge, encumbrance, security interest, claim, easement, restriction, option, covenant and other rights, titles, interests or estates of any nature whatsoever with respect to all or any portion of the Mortgaged Property to the extent that the same may have arisen or intervened during the period between the recordation of this Deed of Trust and the execution of the Lease identified in such instrument of subordination.

(i) Other Rights. Beneficiary (i) may surrender the insurance policies maintained pursuant to Section 4.7 hereof or any part thereof, and upon receipt shall apply the unearned premiums as a credit on the Indebtedness, in accordance with the provisions of Section 7.4 hereof, and, in connection therewith, Grantor hereby appoints Beneficiary as agent and attorney-in-fact (which is coupled with an interest and is therefore irrevocable) for Grantor to collect such premiums; and (ii) apply the reserve for Impositions and insurance premiums, if any, required by the provisions of this Deed of Trust, toward payment of the Indebtedness; and (iii) shall have and may exercise any and all other rights and remedies which Beneficiary may have at law or in equity, or by virtue of any Loan Document or under the Code, or otherwise.

(j) Beneficiary as Purchaser. Beneficiary may be the purchaser of the Mortgaged Property or any part thereof, at any sale thereof, whether such sale be under the power of sale herein vested in Trustee or upon any other foreclosure of the liens and security interests hereof, or otherwise, and Beneficiary shall, upon any such purchase, acquire good title to the Mortgaged Property so purchased, free of the liens and security interests hereof, unless the sale was made subject to an unmatured portion of the Indebtedness. The Beneficiary, as purchaser, shall be treated in the same manner as any third party purchaser and the proceeds of the Beneficiary’s purchase shall be applied in accordance with Section 7.4 of this Deed of Trust.

7.2 Other Rights of Beneficiary. Should any part of the Mortgaged Property come into the possession of Beneficiary, whether before or after default, Beneficiary may (for itself or by or through other persons, firms, or entities) hold, lease, manage, use, or operate the Mortgaged Property for such time and upon such terms as Beneficiary may deem prudent under the circumstances (making such repairs, alterations, additions, and improvements thereto and taking such other action as Beneficiary may from time to time deem necessary or desirable) for the purpose of preserving the Mortgaged Property or its value, pursuant to the order of a court of appropriate jurisdiction or in accordance with any other rights held by Beneficiary in respect of the Mortgaged Property.

7.3 Possession After Foreclosure. If the liens or security interests hereof shall be foreclosed by power of sale granted herein, by judicial action, or otherwise, the purchaser at any such sale shall receive, as an incident to purchaser’s ownership, immediate possession of the property purchased, and if Grantor or Grantor’s successors shall hold possession of said property or any part thereof subsequent to foreclosure, Grantor and Grantor’s successors shall be considered as tenants at sufferance of the purchaser at foreclosure sale (without limitation of

18

other rights or remedies, at a reasonable rental per day, due and payable daily, based upon the value of the portion of the Mortgaged Property so occupied and sold to such purchaser), and anyone occupying such portion of the Mortgaged Property, after demand is made for possession thereof, shall be guilty of forcible detainer and shall be subject to eviction and removal, forcible or otherwise, with or without process of law, and all damages by reason thereof are hereby expressly waived.

7.4 Application of Proceeds. The proceeds from any sale, lease, or other disposition made pursuant to this Article VII, or the proceeds from the surrender of any insurance policies pursuant hereto, or any Rents collected by Beneficiary from the Mortgaged Property, or the reserve for Impositions and insurance premiums, if any, required by the provisions of this Deed of Trust or sums received pursuant to Section 8.1 hereof, or proceeds from insurance which Beneficiary elects to apply to the Indebtedness pursuant to Section 8.2 hereof, shall be applied by Trustee, or by Beneficiary, as the case may be, to the Indebtedness in the following order and priority: (i) to the payment of all expenses of advertising, selling, and conveying the Mortgaged Property or part thereof, and/or prosecuting or otherwise collecting Rents, proceeds, premiums, or other sums including reasonable attorneys’ fees and a reasonable fee or commission to Trustee, not to exceed five percent (5%) of the proceeds thereof or sums so received; (ii) to the remainder of the Indebtedness as follows: first, to the remaining accrued but unpaid interest, second, to the matured portion of principal of the Indebtedness, and third, to prepayment of the unmatured portion, if any, of principal of the Indebtedness applied to installments of principal in inverse order of maturity; (iii) the balance, if any and to the extent applicable, remaining after the full and final payment of the Indebtedness and full performance and discharge of the Obligations to the holder or beneficiary of any inferior liens covering the Mortgaged Property, if any, in order of the priority of such inferior liens (Trustee and Beneficiary shall hereby be entitled to rely exclusively upon a commitment for title insurance issued to determine such priority); and (iv) the cash balance, if any, to the Grantor. The application of proceeds of sale or other proceeds as otherwise provided herein shall be deemed to be a payment of the Indebtedness like any other payment. The balance of the Indebtedness remaining unpaid, if any, shall remain fully due and owing in accordance with the terms of the Credit Agreement, the Notes or the other Loan Documents.

7.5 Abandonment of Sale. In the event a foreclosure hereunder is commenced by Trustee in accordance with Subsection 7.1(d) hereof, at any time before the sale, Trustee may abandon the sale, and Beneficiary may then institute suit for the collection of the Indebtedness and for the foreclosure of the liens and security interests hereof and of the Loan Documents. If Beneficiary should institute a suit for the collection of the Indebtedness and for a foreclosure of the liens and security interests, Beneficiary may, at any time before the entry of a final judgment in said suit, dismiss the same and require Trustee to sell the Mortgaged Property or any part thereof in accordance with the provisions of this Deed of Trust.

7.6 Payment of Fees. If the Notes or any other part of the Indebtedness shall be collected or if any of the Obligations shall be enforced by legal proceedings, whether through a probate or bankruptcy court or otherwise, or shall be placed in the hands of an attorney for collection after maturity, whether matured by the expiration of time or by an option given to the Beneficiary to mature same, or if Beneficiary becomes a party to any suit where this Deed of Trust or the Mortgaged Property or any part thereof is involved, Grantor agrees to pay

19

Beneficiary’s attorneys’ fees and expenses incurred, and such fees shall be and become a part of the Indebtedness and shall bear interest from the date such costs are incurred at the Default Rate.

7.7 Miscellaneous.

(a) In case Beneficiary shall have proceeded to invoke any right, remedy, or recourse permitted under the Loan Documents and shall thereafter elect to discontinue or abandon same for any reason, Beneficiary shall have the unqualified right so to do and, in such event, Grantor and Beneficiary shall be restored to their former positions with respect to the Indebtedness, the Loan Documents, the Mortgaged Property or otherwise, and the rights, remedies, recourses and powers of Beneficiary shall continue as if same had never been invoked.

(b) In addition to the remedies set forth in this Article, upon the occurrence of an Event of Default, the Beneficiary and Trustee shall, in addition, have all other remedies available to them at law or in equity.

(c) All rights, remedies, and recourses of Beneficiary granted in the Credit Agreement, the Notes, this Deed of Trust, the other Loan Documents, any other pledge of collateral, or otherwise available at law or equity: (i) shall be cumulative and concurrent; (ii) may be pursued separately, successively, or concurrently against Grantor, the Mortgaged Property, or any one or more of them, at the sole discretion of Beneficiary; (iii) may be exercised as often as occasion therefor shall arise, it being agreed by Grantor that the exercise or failure to exercise any of same shall in no event be construed as a waiver or release thereof or of any other right, remedy, or recourse; (iv) shall be nonexclusive; (v) shall not be conditioned upon Beneficiary exercising or pursuing any remedy in relation to the Mortgaged Property prior to Beneficiary bringing suit to recover the Indebtedness or suit on the Obligations; and (vi) in the event Beneficiary elects to bring suit on the Indebtedness and/or the Obligations and obtains a judgment against Grantor prior to exercising any remedies in relation to the Mortgaged Property, all liens and security interests, including the lien of this Deed of Trust, shall remain in full force and effect and may be exercised at Beneficiary’s option.

(d) Beneficiary may release, regardless of consideration, any part of the Mortgaged Property without, as to the remainder, in any way impairing, affecting, subordinating, or releasing the lien or security interests evidenced by this Deed of Trust or the other Loan Documents or affecting the obligations of Grantor or any other party to pay the Indebtedness or perform and discharge the Obligations. For payment of the Indebtedness, Beneficiary may resort to any of the collateral therefor in such order and manner as Beneficiary may elect. No collateral heretofore, herewith, or hereafter taken by Beneficiary shall in any manner impair or affect the collateral given pursuant to the Loan Documents, and all collateral shall be taken, considered, and held as cumulative.

(e) Grantor hereby irrevocably and unconditionally waives and releases: (i) all benefits that might accrue to Grantor by virtue of any present or future law exempting the Mortgaged Property from attachment, levy or sale on execution or providing for any appraisement, valuation, stay of execution, exemption from civil

20

process, redemption, or extension of time for payment; (ii) all notices of any Event of Default or of Trustee’s exercise of any right, remedy, or recourse provided for under the Loan Documents; and (iii) any right to a marshalling of assets or a sale in inverse order of alienation.

(f) Grantor and Beneficiary mutually agree that there are no, nor shall there be any, implied covenants of good faith and fair dealing or other similar covenants or agreements in this Deed of Trust, the Notes, the Credit Agreement and the other Loan Documents. All agreed contractual duties are set forth in this Deed of Trust, the Notes, the Credit Agreement and the other Loan Documents.

(g) The remedies in this Article VII, as to interests in real property, are available under and governed by the real property laws of Texas and are not governed by the personal property laws of Texas, including but not limited to, the power to dispose of personal property in a commercially reasonable manner under Sections 9.610 through and including 9.618, and 9.624 of the Code.

7.8 Waiver of Deficiency Statute.

(a) In the event an interest in any of the Mortgaged Property is foreclosed upon pursuant to a judicial or nonjudicial foreclosure sale, Grantor agrees as follows. Notwithstanding the provisions of Sections 51.003, 51.004, and 51.005 of the Texas Property Code (as the same may be amended from time to time), and to the extent permitted by law, Grantor agrees that Beneficiary shall be entitled to seek a deficiency judgment from Grantor and any other party obligated on the Notes equal to the difference between the amount owing on the Notes and the amount for which the Mortgaged Property was sold pursuant to judicial or nonjudicial foreclosure sale. Grantor expressly recognizes that this section constitutes a waiver of the above-cited provisions of the Texas Property Code which would otherwise permit Grantor and other persons against whom recovery of deficiencies is sought or Guarantor independently (even absent the initiation of deficiency proceedings against them) to present competent evidence of the fair market value of the Mortgaged Property as of the date of the foreclosure sale and offset against any deficiency the amount by which the foreclosure sale price is determined to be less than such fair market value. Grantor further recognizes and agrees that this waiver creates an irrebuttable presumption that the foreclosure sale price is equal to the fair market value of the Mortgaged Property for purposes of calculating deficiencies owed by Grantor, Guarantor, and others against whom recovery of a deficiency is sought.

(b) Alternatively, in the event the waiver provided for in subsection (a) above is determined by a court of competent jurisdiction to be unenforceable, the following shall be the basis for the finder of fact’s determination of the fair market value of the Mortgaged Property as of the date of the foreclosure sale in proceedings governed by Sections 51.003, 51.004 and 51.005 of the Texas Property Code (as amended from time to time): (i) the Mortgaged Property shall be valued in an “as is” condition as of the date of the foreclosure sale, without any assumption or expectation that the Mortgaged Property will be repaired or improved in any manner before a resale of the Mortgaged

21

Property after foreclosure; (ii) the valuation shall be based upon an assumption that the foreclosure purchaser desires a resale of the Mortgaged Property for cash promptly (but no later than twelve (12) months) following the foreclosure sale; (iii) all reasonable closing costs customarily borne by the seller in commercial real estate transactions should be deducted from the gross fair market value of the Mortgaged Property, including, without limitation, brokerage commissions, title insurance, a survey of the Mortgaged Property, tax prorations, attorneys’ fees, and marketing costs; (iv) the gross fair market value of the Mortgaged Property shall be further discounted to account for any estimated holding costs associated with maintaining the Mortgaged Property pending sale, including, without limitation, utilities expenses, property management fees, taxes and assessments (to the extent not accounted for in (iii) above), and other maintenance, operational and ownership expenses; and (v) any expert opinion testimony given or considered in connection with a determination of the fair market value of the Mortgaged Property must be given by persons having at least five (5) years experience in appraising property similar to the Mortgaged Property and who have conducted and prepared a complete written appraisal of the Mortgaged Property taking into consideration the factors set forth above.

ARTICLE VIII

Beneficiary shall be entitled to exercise both the rights of setoff and banker’s lien, if applicable, against the interest of Grantor in and to each and every account and other property of Grantor which are in the possession of Beneficiary to the full extent of the outstanding balance of the Indebtedness.

8.6 Consent to Disposition. It is expressly agreed that Beneficiary may predicate Beneficiary’s decision to grant or withhold consent to a Disposition on such terms and conditions as Beneficiary may require, in Beneficiary’s sole discretion, including without limitation (i) consideration of the creditworthiness of the party to whom such Disposition will be made and its management ability with respect to the Mortgaged Property, (ii) consideration of whether the security for repayment of the Indebtedness and the performance and discharge of the Obligations, or Beneficiary’s ability to enforce its rights, remedies, and recourses with respect to such security, will be impaired in any way by the proposed Disposition, (iii) an increase in the rate of interest payable under the Notes or any other change in the terms and provisions of the Notes and other Loan Documents, (iv) reimbursement of Beneficiary for all reasonable costs and

24

expenses incurred by Beneficiary in investigating the creditworthiness and management ability of the party to whom such Disposition will be made and in determining whether Beneficiary’s security will be impaired by the proposed Disposition, (v) payment to Beneficiary of a transfer fee to cover the cost of documenting the Disposition in its records, (vi) payment of Beneficiary’s reasonable attorneys’ fees in connection with such Disposition, (vii) the express assumption of payment of the Indebtedness and performance and discharge of the Obligations by the party to whom such Disposition will be made (with or without the release of Grantor from liability for such Indebtedness and Obligations), (viii) the execution of assumption agreements, modification agreements, supplemental loan documents, and financing statements, satisfactory in form and substance to Beneficiary, (ix) endorsements (to the extent available under applicable law) to any existing mortgagee title insurance policies insuring Beneficiary’s liens and security interests covering the Mortgaged Property, and (x) require additional security for the payment of the Indebtedness and performance and discharge of the Obligations.

8.7 Consent to Subordinate Mortgage. In the event of consent by Beneficiary to the granting of a Subordinate Mortgage, or in the event the above-described right of Beneficiary to declare the Indebtedness to be immediately due and payable upon the granting of a Subordinate Mortgage without the prior written consent of Beneficiary is determined by a court of competent jurisdiction to be unenforceable under the provisions of any applicable law, Grantor will not execute or deliver any Subordinate Mortgage unless (i) it shall contain express covenants to the effect: (a) that the Subordinate Mortgage is in all respects unconditionally subject and subordinate to the lien and security interest evidenced by this Deed of Trust and each term and provision hereof; (b) that if any action or proceeding shall be instituted to foreclose the Subordinate Mortgage (regardless of whether the same is a judicial proceeding or pursuant to a power of sale contained therein), no tenant of any portion of the Mortgaged Property will be named as a party defendant, nor will any action be taken with respect to the Mortgaged Property which would terminate any occupancy or tenancy of the Mortgaged Property without the prior written consent of Beneficiary; (c) that the rents and profits, if collected through a receiver or by the holder of the Subordinate Mortgage, shall be applied first to the Indebtedness, next to the payment of the Impositions, and then to the performance and discharge of the Obligations; and (d) that if any action or proceeding shall be brought to foreclose the Subordinate Mortgage (regardless of whether the same is a judicial proceeding or pursuant to a power of sale contained therein), written notice of the commencement thereof will be given to Beneficiary contemporaneously with the commencement of such action or proceeding; and (ii) a copy thereof shall have been delivered to Beneficiary not less than ten (10) days prior to the date of the execution of such Subordinate Mortgage.

Notwithstanding anything herein to the contrary, Grantor may terminate the Lease with the prior owner of the Land under which Grantor is the lessee.

9.2 Limited License. Beneficiary hereby grants to Grantor a limited license (the “License”), nonexclusive with the rights of Beneficiary reserved in Section 9.4 hereof, to exercise and enjoy all incidences of the status of a lessor of the Leases and the Rents, including without limitation, the right to collect, demand, sue for, attach, levy, recover, and receive the Rents, and to give proper receipts, releases, and acquittances therefor. Grantor hereby agrees to receive all Rents and hold the same as a trust fund to be applied, and to apply the Rents so collected, first to the payment of the Indebtedness, next to the payment of the Impositions, and then to the performance and discharge of the Obligations. Thereafter, Grantor may use the balance of the Rent collected in any manner not inconsistent with the Loan Documents.

9.3 Enforcement of Leases. So long as the License is in effect, Grantor shall (i) submit any and all proposed Leases to Beneficiary for approval prior to the execution thereof, (ii) duly and punctually perform and comply with any and all representations, warranties, covenants, and agreements expressed as binding upon the lessor under any Lease, (iii) maintain each of the Leases in full force and effect during the term thereof, (iv) appear in and defend any action or proceeding in any manner connected with any of the Leases, (v) deliver to Beneficiary copies of all Leases, and (vi) deliver to Beneficiary such further information, and execute and deliver to Beneficiary such further assurances and assignments, with respect to the Leases as Beneficiary may from time to time request.

Notwithstanding anything herein to the contrary, Grantor may terminate the Lease with the prior owner of the Land under which Grantor is the lessee.

9.4 No Merger of Estates. So long as any part of the Indebtedness and the Obligations secured hereby remain unpaid and unperformed or undischarged, the fee and leasehold estates to the Mortgaged Property shall not merge but rather shall remain separate and distinct, notwithstanding the union of such estates either in Grantor, Beneficiary, any lessee, or any third party purchaser or otherwise.

ARTICLE XI

CONCERNING THE TRUSTEE

11.1 No Required Action. Trustee shall not be required to take any action toward the execution and enforcement of the trust hereby created or to institute, appear in, or defend any action, suit, or other proceeding in connection therewith where, in his opinion, such action would be likely to involve him in expense or liability, unless requested so to do by a written instrument signed by Beneficiary and, if Trustee so requests, unless Trustee is tendered security and indemnity satisfactory to Trustee against any and all cost, expense, and liability arising

27

therefrom. Trustee shall not be responsible for the execution, acknowledgment, or validity of the Loan Documents, or for the proper authorization thereof, or for the sufficiency of the lien and security interest purported to be created hereby, and Trustee makes no representation in respect thereof or in respect of the rights, remedies, and recourses of Beneficiary.

11.2 Certain Rights. With the approval of Beneficiary, Trustee shall have the right to take any and all of the following actions: (i) to select, employ, and advise with counsel (who may be, but need not be, counsel for Beneficiary) upon any matters arising hereunder, including the preparation, execution, and interpretation of the Loan Documents, and shall be fully protected in relying as to legal matters on the advice of counsel, (ii) to execute any of the trusts and powers hereof and to perform any duty hereunder either directly or through his agents or attorneys, (iii) to select and employ, in and about the execution of his duties hereunder, suitable accountants, engineers and other experts, agents and attorneys-in-fact, either corporate or individual, not regularly in the employ of Trustee, and Trustee shall not be answerable for any act, default, negligence, or misconduct of any such accountant, engineer or other expert, agent or attorney-in-fact, if selected with reasonable care, or for any error of judgment or act done by Trustee in good faith, or be otherwise responsible or accountable under any circumstances whatsoever, except for Trustee’s gross negligence or bad faith, and (iv) any and all other lawful action as Beneficiary may instruct Trustee to take to protect or enforce Beneficiary’s rights hereunder. Trustee shall not be personally liable in case of entry by Trustee, or anyone entering by virtue of the powers herein granted to Trustee, upon the Mortgaged Property for debts contracted for or liability or damages incurred in the management or operation of the Mortgaged Property. Trustee shall have the right to rely on any instrument, document, or signature authorizing or supporting any action taken or proposed to be taken by Trustee hereunder, believed by Trustee in good faith to be genuine. Trustee shall be entitled to reimbursement for expenses incurred by Trustee in the performance of Trustee’s duties hereunder and to reasonable compensation for such of Trustee’s services hereunder as shall be rendered. Grantor will, from time to time, pay the compensation due to Trustee hereunder and reimburse Trustee for, and save Trustee harmless against, any and all liability and expenses which may be incurred by Trustee in the performance of Trustee’s duties.

11.3 Retention of Money. All monies received by Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated in any manner from any other monies (except to the extent required by applicable law) and Trustee shall be under no liability for interest on any monies received by Trustee hereunder.

11.4 Successor Trustees. Trustee may resign by the giving of notice of such resignation in writing or verbally to Beneficiary. If Trustee shall die, resign, or become disqualified from acting in the execution of this trust, or if, for any reason, Beneficiary shall prefer to appoint a substitute trustee or multiple substitute trustees, or successive substitute trustees or successive multiple substitute trustees, to act instead of the aforenamed Trustee, Beneficiary shall have full power to appoint a substitute trustee (or, if preferred, multiple substitute trustees) in succession who shall succeed (and if multiple substitute trustees are appointed, each of such multiple substitute trustees shall succeed) to all the estates, rights, powers, and duties of the aforenamed Trustee. Such appointment may be executed by any authorized agent of Beneficiary, and if such Beneficiary be a corporation and such appointment

28

be executed in its behalf by any officer of such corporation, such appointment 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 the corporation. Grantor hereby ratifies and confirms any and all acts which the aforenamed Trustee, or his successor or successors in this trust, shall do lawfully by virtue hereof. If multiple substitute Trustees are appointed, each of such multiple substitute Trustees shall be empowered and authorized to act alone without the necessity of the joinder of the other multiple substitute trustees, whenever any action or undertaking of such substitute trustees is requested or required under or pursuant to this Deed of Trust or applicable law.

11.5 Perfection of Appointment. Should any deed, conveyance, or instrument of any nature be required from Grantor by any Trustee or substitute Trustee to more fully and certainly vest in and confirm to the Trustee or substitute Trustee such estates, rights, powers, and duties, then, upon request by the Trustee or substitute Trustee, any and all such deeds, conveyances and instruments shall be made, executed, acknowledged, and delivered and shall be caused to be recorded and/or filed by Grantor.

11.6 Succession Instruments. Any substitute Trustee appointed pursuant to any of the provisions hereof shall, without any further act, deed, or conveyance, become vested with all the estates, properties, rights, powers, and trusts of its or his predecessor in the rights hereunder with like effect as if originally named as Trustee herein; but nevertheless, upon the written request of Beneficiary or of the substitute Trustee, the Trustee ceasing to act shall execute and deliver any instrument transferring to such substitute Trustee, upon the trusts herein expressed, all the estates, properties, rights, powers, and trusts of the Trustee so ceasing to act, and shall duly assign, transfer and deliver any of the property and moneys held by such Trustee to the substitute Trustee so appointed in the Trustee’s place.

11.7 No Representation by Trustee or Beneficiary. By accepting or approving anything required to be observed, performed, or fulfilled or to be given to Trustee or Beneficiary pursuant to the Loan Documents, including without limitation, any officer’s certificate, balance sheet, statement of profit and loss or other financial statement, survey, appraisal, or insurance policy, neither Trustee nor Beneficiary shall be deemed to have warranted, consented to, or affirmed the sufficiency, legality, effectiveness, or legal effect of the same, or of any term, provision, or condition thereof, and such acceptance or approval thereof shall not be or constitute any warranty or affirmation with respect thereto by Trustee or Beneficiary.

ARTICLE XII

MISCELLANEOUS

12.1 Release. If the Indebtedness is paid in full in accordance with the terms of this Deed of Trust, the Credit Agreement, the Notes, and the other Loan Documents, and if Grantor shall well and truly perform each and every of the Obligations to be performed and discharged in accordance with the terms of this Deed of Trust, the Credit Agreement, the Notes and the other Loan Documents, then this conveyance shall become null and void and be released at Grantor’s

29

request and expense, and Beneficiary shall have no further obligation to make advances under and pursuant to the provisions hereof or in the other Loan Documents.

12.2 Performance at Grantor’s Expense. Subject to the provisions of Section 12.11 hereof, Grantor shall (i) pay all legal fees incurred by Beneficiary in connection with the preparation of the Loan Documents (including any amendments thereto or consents, releases, or waivers granted thereunder); (ii) reimburse Beneficiary, promptly upon demand, for all amounts expended, advanced, or incurred by Beneficiary to satisfy any obligation of Grantor under the Loan Documents, which amounts shall include all court costs, attorneys’ fees (including, without limitation, for trial, appeal, or other proceedings), fees of auditors and accountants and other investigation expenses reasonably incurred by Beneficiary in connection with any such matters; and (iii) any and all other costs and expenses of performing or complying with any and all of the Obligations. Except to the extent that costs and expenses are included within the definition of “Indebtedness,” the payment of such costs and expenses shall not be credited, in any way and to any extent, against any installment on or portion of the Indebtedness.

12.3 Survival of Obligations. Each and all of the Obligations shall survive the execution and delivery of the Loan Documents and the consummation of the loan called for therein and shall continue in full force and effect until the Indebtedness shall have been paid in full; provided, however, that nothing contained in this Section shall limit the obligations of Grantor as otherwise set forth herein.

12.4 Recording and Filing. Grantor will cause the Loan Documents (requested by the Beneficiary) and all amendments and supplements thereto and substitutions therefor to be recorded, filed, re-recorded, and refiled in such manner and in such places as Trustee or Beneficiary shall reasonably request, and will pay all such recording, filing, re-recording and refiling taxes, documentary stamp taxes, fees, and other charges.

12.5 Notices. All notices or other communications required or permitted to be given pursuant to this Deed of Trust shall be in writing and shall be considered as properly given if (i) mailed by first class United States mail, postage prepaid, registered or certified with return receipt requested, (ii) by delivering same in person to the intended addressee, (iii) by delivery to an independent third party commercial delivery service for same day or next day delivery and providing for evidence of receipt at the office of the intended addressee, or (iv) by prepaid telegram, telex, or telefacsimile to the addressee. Notice so mailed shall be effective upon its deposit with the United States Postal Service or any successor thereto; notice sent by such a commercial delivery service shall be effective upon delivery to such commercial delivery service; notice given by personal delivery shall be effective only if and when received by the addressee; and notice given by other means shall be effective only if and when received at the office or designated place or machine of the intended addressee. For purposes of notice, the addresses of the parties shall be as set forth herein; provided, however, that either party shall have the right to change its address for notice hereunder to any other location within the continental United States by the giving of thirty (30) days’ notice to the other party in the manner set forth herein.

12.6 Covenants Running with the Land. All Obligations contained in this Deed of Trust and the other Loan Documents are intended by Grantor, Beneficiary, and Trustee to be, and

30

shall be construed as, covenants running with the Mortgaged Property until the lien of this Deed of Trust has been fully released by Beneficiary.

12.7 Successors and Assigns. Subject to the provisions of Section 6.3 hereof, all of the terms of the Loan Documents shall apply to, be binding upon, and inure to the benefit of the parties thereto, their successors, assigns, heirs, and legal representatives, and all other persons claiming by, through, or under them, except as otherwise expressly provided herein or in such Loan Documents.

12.8 No Waiver; Severability. Any failure by Trustee or Beneficiary to insist, or any election by Trustee or Beneficiary not to insist, upon strict performance by Grantor or others of any of the terms, provisions, or conditions of the Loan Documents shall not be deemed to be a waiver of same or of any other terms, provisions, or conditions thereof, and Trustee or Beneficiary shall have the right at any time or times thereafter to insist upon strict performance by Grantor or others of any and all of such terms, provisions, and conditions. The Loan Documents are intended to be performed in accordance with, and only to the extent permitted by, all applicable Legal Requirements. If any provision of any of the Loan Documents or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, then neither the remainder of the instrument in which such provision is contained nor the application of such provision to other persons or circumstances nor the other instruments referred to herein shall be affected thereby, but rather shall be enforced to the greatest extent permitted by law.

12.9 Counterparts. To facilitate execution, this Deed of Trust may be executed in as many counterparts as may be convenient or required. It shall not be necessary that the signature and acknowledgment of, or on behalf of, each party, or that the signature and acknowledgment of all persons required to bind any party, appear on each counterpart. All counterparts shall collectively constitute a single instrument. It shall not be necessary in making proof of this Deed of Trust to produce or account for more than a single counterpart containing the respective signatures and acknowledgment of, or on behalf of, each of the parties hereto. Any signature and acknowledgment page to any counterpart may be detached from such counterpart without impairing the legal effect of the signatures and acknowledgments thereon and thereafter attached to another counterpart identical thereto except having attached to it additional signature and acknowledgment pages.

12.10 Applicable Law. The Loan Documents shall be governed by and construed according to the laws of the State of Texas from time to time in effect except to the extent preempted by United States federal law.

12.11 Interest Provisions.

(a) Savings Clause. It is expressly stipulated and agreed to be the intent of Grantor and Beneficiary at all times to comply strictly with the applicable Texas law governing the maximum rate or amount of interest payable on the Notes or the Related Indebtedness (or applicable United States federal law to the extent that it permits Beneficiary to contract for, charge, take, reserve or receive a greater amount of interest than under Texas law). If the applicable law is ever judicially interpreted so as to render

31

usurious any amount (i) contracted for, charged, taken, reserved or received pursuant to the Notes, any of the other Loan Documents or any other communication or writing by or between Grantor and Beneficiary related to the transaction or transactions that are the subject matter of the Loan Documents, (ii) contracted for, charged or received by reason of Beneficiary’s exercise of the option to accelerate the maturity of the Notes and/or the Related Indebtedness, or (iii) Grantor will have paid or Beneficiary will have received by reason of any voluntary prepayment by Borrower of the Notes and/or the Related Indebtedness, then it is Grantor’s and Beneficiary’s express intent that all amounts charged in excess of the Maximum Rate shall be automatically cancelled, ab initio, and all amounts in excess of the Maximum Rate theretofore collected by Beneficiary shall be credited on the principal balance of the Notes and/or the Related Indebtedness (or, if the Notes and all Related Indebtedness have been or would thereby be paid in full, refunded to Grantor), and the provisions of the Notes and the other Loan Documents immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder; provided, however, if the Notes have been paid in full before the end of the stated term of the Notes, then Grantor and Beneficiary agree that Beneficiary shall, with reasonable promptness after Beneficiary discovers or is advised by Grantor that interest was received in an amount in excess of the Maximum Rate, either refund such excess interest to Grantor and/or credit such excess interest against the Notes and/or any Related Indebtedness then owing by Grantor to Beneficiary. Grantor hereby agrees that as a condition precedent to any claim seeking usury penalties against Beneficiary, Grantor will provide written notice to Beneficiary, advising Beneficiary in reasonable detail of the nature and amount of the violation, and Beneficiary shall have sixty (60) days after receipt of such notice in which to correct such usury violation, if any, by either refunding such excess interest to Grantor or crediting such excess interest against the Notes and/or the Related Indebtedness then owing by Grantor to Beneficiary. All sums contracted for, charged or received by Beneficiary for the use, forbearance or detention of any debt evidenced by the Notes and/or the Related Indebtedness shall, to the extent permitted by applicable law, be amortized or spread, using the actuarial method, throughout the stated term of the Notes and/or the Related Indebtedness (including any and all renewal and extension periods) until payment in full so that the rate or amount of interest on account of the Notes and/or the Related Indebtedness does not exceed the Maximum Rate from time to time in effect and applicable to the Notes and/or the Related Indebtedness for so long as debt is outstanding. In no event shall the provisions of Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving triparty accounts) apply to the Notes and/or the Related Indebtedness. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Beneficiary to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration.

(b) Definitions. As used herein, the term “Maximum Rate” shall mean the maximum lawful rate of interest which may be contracted for, charged, taken, received or reserved by Beneficiary in accordance with the applicable laws of the State of Texas (or applicable United States federal law to the extent that it permits Beneficiary to contract

32

for, charge, take, receive or reserve a greater amount of interest than under Texas law), taking into account all Charges (as herein defined) made in connection with the transaction evidenced by the Notes and the other Loan Documents. As used herein, the term “Charges” shall mean all fees, charges and/or any other things of value, if any, contracted for, charged, received, taken or reserved by Beneficiary in connection with the transactions relating to the Notes and the other Loan Documents, which are treated as interest under applicable law. As used herein, the term “Related Indebtedness” shall mean any and all debt paid or payable by Grantor to Beneficiary pursuant to the Loan Documents or any other communication or writing by or between Grantor and Beneficiary related to the transaction or transactions that are the subject matter of the Loan Documents, except such debt which has been paid or is payable by Grantor to Beneficiary under the Notes.

(c) Ceiling Election. To the extent that Beneficiary is relying on the Texas Finance Code to determine the Maximum Lawful Rate payable on the Notes and/or the Related Indebtedness, Beneficiary will utilize the weekly ceiling from time to time in effect as provided in such Chapter 303, as amended. To the extent United States federal law permits Beneficiary to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law, Beneficiary will rely on United States federal law instead of such Chapter 303 for the purpose of determining the Maximum Rate. Additionally, to the extent permitted by applicable law now or hereafter in effect, Beneficiary may, at its option and from time to time, utilize any other method of establishing the Maximum Rate under such Chapter 303 or under other applicable law by giving notice, if required, to Grantor as provided by applicable law now or hereafter in effect.

12.12 Subrogation. If any or all of the proceeds of the Notes have been used to extinguish, extend or renew any indebtedness heretofore existing against the Mortgaged Property, then, to the extent of such funds so used, Beneficiary shall be subrogated to all of the rights, claims, liens, titles, and interests existing against the Mortgaged Property heretofore held by, or in favor of, the holder of such indebtedness and such former rights, claims, liens, titles, and interests, if any, are not waived but rather are continued in full force and effect in favor of Beneficiary and are merged with the lien and security interest created herein as cumulative security for the repayment of the Indebtedness and the performance and discharge of the Obligations.

12.13 Rights Cumulative. Beneficiary shall have all rights, remedies, and recourses granted in the Loan Documents and available at law or in equity (including, without limitation, those granted by the Code and applicable to the Mortgaged Property or any portion thereof), and the same (i) shall be cumulative and concurrent, (ii) may be pursued separately, successively, or concurrently against Grantor or others obligated for the Indebtedness or any part thereof, or against any one or more of them, or against the Mortgaged Property, at the sole discretion of Beneficiary, (iii) may be exercised as often as occasion therefor shall arise, it being agreed by Grantor that the exercise, discontinuance of the exercise of or failure to exercise any of the same shall in no event be construed as a waiver or release thereof or of any other right, remedy, or recourse, and (iv) are intended to be, and shall be, nonexclusive. All rights and remedies of Beneficiary hereunder and under the other Loan Documents shall extend to any period after the

33

initiation of foreclosure proceedings, judicial or otherwise, with respect to the Mortgaged Property.

12.14 Payments. Remittances in payment of any part of the Indebtedness other than in the required amount in funds immediately available at the place where the Notes are payable shall not, regardless of any receipt or credit issued therefor, constitute payment until the required amount is actually received by Beneficiary in funds immediately available at the place where the Notes are payable (or such other place as Beneficiary, in Beneficiary’s sole discretion, may have established by delivery of written notice thereof to Grantor) and shall be made and accepted subject to the condition that any check or draft may be handled for collection in accordance with the practice of the collecting bank or banks. Acceptance by Beneficiary of any payment in an amount less than the amount then due shall be deemed an acceptance on account only, and the failure to pay the entire amount then due shall be and continue to be an Event of Default.

12.15 Exceptions to Covenants. Grantor shall not be deemed to be permitted to take any action or to fail to take any action with respect to any particular covenant or condition contained herein or in any of the Loan Documents if the action or omission would result in the breach of any other covenant or condition contained herein or in any of the Loan Documents which has not been specifically waived or consented to by Beneficiary, nor shall Beneficiary be deemed to have consented to any such act or omission if the same would provide cause for acceleration of the Indebtedness as a result of the breach of any other covenant or condition contained herein or in any of the Loan Documents which has not been specifically waived or consented to by Beneficiary.

12.16 Reliance. Grantor recognizes and acknowledges that in entering into the loan transaction evidenced by the Loan Documents and accepting this Deed of Trust, Beneficiary is expressly and primarily relying on the truth and accuracy of the foregoing warranties and representations set forth in Article III hereof without any obligation to investigate the Mortgaged Property and notwithstanding any investigation of the Mortgaged Property by Beneficiary; that such reliance exists on the part of Beneficiary prior hereto; that such warranties and representations are a material inducement to Beneficiary in making the loan evidenced by the Loan Documents and accepting of this Deed of Trust; and that Beneficiary would not be willing to make the loan evidenced by the Loan Documents and accept this Deed of Trust in the absence of any of such warranties and representations.

12.17 Change of Security. Any part of the Mortgaged Property may be released, regardless of consideration, by Beneficiary from time to time without impairing, subordinating, or affecting in any way the lien, security interest, and other rights hereof against the remainder. The lien, security interest, and other rights granted hereby shall not be affected by any other security taken for the Indebtedness or Obligations, or any part thereof. The taking of additional collateral, or the amendment, extension, renewal, or rearrangement of the Indebtedness or Obligations, or any part thereof, shall not release or impair the lien, security interest, and other rights granted hereby, or affect the liability of any endorser or guarantor or improve the right of any junior lienholder; and this Deed of Trust, as well as any instrument given to secure any amendment, extension, renewal, or rearrangement of the Indebtedness or Obligations, or any part thereof, shall be and remain a first and prior lien, except as otherwise provided herein, on all of

34

the Mortgaged Property not expressly released until the Indebtedness is fully paid and the Obligations are fully performed and discharged.

12.18 [Reserved.]

12.19 Headings. The Article, Section, and Subsection entitlements hereof are inserted for convenience of reference only and shall in no way alter, modify, or define, or be used in construing the text of such Articles, Sections, or Subsections.

12.20 Entire Agreement; Amendment.
