Quiet Enjoyment. Sublessor covenants that Sublessee shall, and may peacefully have, hold and enjoy the Subleased Premises against any person whomsoever lawfully claiming the same or any part thereof by, through, or under Sublessor, but not otherwise, subject to the other provisions hereof, provided that Sublessee pays the Rent (as hereinafter defined) and other sums 2 herein recited to be paid by Sublessee and performs all of Sublessee's covenants and agreements herein contained. 3. TERM. 3.1. Term. Sublessee will occupy the Subleased Premises in two phases.

Although Rent will commence in phases, as described in Paragraph 3.3 below, the term of this Sublease for the entire Subleased Premises shall begin on the Commencement Date (as defined below), and end at midnight on October 31, 2001 (the "EXPIRATION Date"). The "COMMENCEMENT DATE" shall be the earlier of the date upon which Sublessee first occupies for business purposes any portion of the Phase I Premises or April 1, 1995. Immediately after occupying each phase of the Subleased Premises, Sublessee shall execute and deliver to Sublessor a statement prepared by Sublessor confirming the Commencement Date, the Rent commencement date with respect to such phase, and the Expiration Date. 3.2. Delivery of Phase I and Phase II Premises. Sublessee acknowledges that Sublessor presently occupies the Subleased Premises. Sublessor will vacate the Phase I Premises by or before February 1, 1995 (the "PHASE I DELIVERY DATE"), and Sublessor will vacate the Phase II Premises by or before April 1, 1995 (the "PHASE II DELIVERY DATE").

Rent for the Phase I Premises and the Existing Furniture (as defined in Paragraph 22) located in the Phase I Premises ("PHASE I FURNITURE") shall commence on the Commencement Date; and Rent for the Phase II Premises and the Existing Furniture located in the Phase II Premises ("PHASE II FURNITURE") shall commence on the earlier of the date upon which Sublessee first occupies for business purposes any portion of the Phase II Premises or July 1, 1995. 4. BASE RENT; SECURITY DEPOSIT. 4.1. Base Rent. During each year of the term of this Sublease, Sublessee shall pay to Sublessor annual base rent equal to the product of the number of square feet of Net Rentable Area in the Subleased Premises times $13.35 (the "BASE RENT"). 4.2. Payment of Base Rent. The annual Base Rent shall be payable in equal monthly installments equal to 1/12th of the Base Rent. Each installment of Base Rent shall be due on or before the first day of each month during the term of this Sublease and shall -2- 3 be paid to Sublessor at its address as set forth in Paragraph 24.4 (or as later changed pursuant thereto) without notice, demand, abatement, deduction, diminution, or offset. Monthly installments of Base Rent shall be prorated for any period during the term hereof which is less than a full calendar month. The initial installment of Base Rent shall be paid upon the Commencement Date. 4.3. Security Deposit. Upon the execution of this Sublease, Sublessee shall deposit with Sublessor a security deposit in the amount of $367,662.00 (the "SECURITY DEPOSIT") as security for the performance of the terms and provisions hereof by Sublessee. Sublessor will deposit the Security Deposit in one or more federally insured interest bearing accounts established solely for the purpose of holding the Security Deposit. The name of any such account shall be the "Oryx/Lacerte Security Deposit Trust Account", or a name similar thereto, and Sublessor will not commingle the Security Deposit with Sublessor's other funds. The term of any such interest bearing account deposit shall be approximately as long as the term of this Sublease. Provided Sublessee is not then in default under this Sublease, interest from time to time paid to Sublessor on account of the Security Deposit shall be disbursed to Sublessee within 30 days after Sublessor's receipt of the same; provided, however, Sublessor may reserve from such interest payments such amounts as may be reasonably required to pay any early withdrawal penalty that might be required during the term of this Sublease. The Security Deposit or any portion thereof may be applied to the curing of any default by Sublessee under this Sublease, without prejudice to any other remedy or remedies which Sublessor may have on account thereof, and upon such application Sublessee shall pay Sublessor on demand the amount so applied which shall be added to the Security Deposit. Provided Sublessee is not then in default under this Sublease, any remaining balance of the Security Deposit will be returned to Sublessee within 30 days after the expiration of the term of this Sublease; provided, however, Sublessor shall have the right to retain and expend all or any portion of the Security Deposit for cleaning and repairing the Subleased Premises to the extent Sublessee fails to deliver the Subleased Premises at the termination of this Sublease in a neat and clean condition and in as good a condition as existed at the date of possession of same by Sublessee, except for ordinary wear and tear. If Sublessor assigns its interest in the Subleased Premises during the term hereof, Sublessor may assign the Security Deposit to the assignee, and thereafter Sublessor shall have no further liability for the return of the Security Deposit, or any interest thereon, and Sublessee agrees to look solely to the new sublessor for the return of the Security Deposit, and any interest thereon. 5. ADDITIONAL RENT. 5.1. Certain Definitions. For purposes hereof: "BASE YEAR" means the calendar year 1995; "SUBLESSEE'S PERCENTAGE SHARE" means the proportion which the Net Rentable Area in the Subleased -3- 4 Premises, from time to time, bears to the total Net Rentable Area in the Leased Premises, from time to time; "TENANT'S PERCENTAGE SHARE OF OPERATING EXPENSES" has the same meaning given to such term in the Master Lease; "SUBLESSEE'S PERCENTAGE SHARE OF OPERATING EXPENSES" means an amount equal to Tenant's Percentage Share of Operating Expenses attributable to the Subleased Premises during any calendar year of the term of this Sublease; "SUBLESSEE'S PERCENTAGE SHARE OF EXCESS 0PERATING EXPENSES" means the difference in any calendar year after the Base Year between Sublessee's Percentage Share of Operating Expenses in that year and Sublessee's Percentage Share of Operating Expenses in the Base Year. 5.2. Additional Rent. In addition to Base Rent, Sublessee shall also pay to Sublessor, during the term of this Sublease, at the same time as Base Rent is due, an amount equal to Sublessee's Percentage Share of Excess Operating Expenses. The parties acknowledge that the Master Lease requires Sublessor to pay on a monthly basis certain estimated costs in order to reimburse Master Lessor, over the course of each year of the term of the Master Lease, for Sublessor's share of "OPERATING EXPENSES" (as defined in the Master Lease) incurred by Master Lessor in owning and operating the "PROJECT" (as defined in the Master Lease). Sublessee agrees to pay on a monthly basis those estimated Operating Expenses attributable to Sublessee's Percentage Share of Excess operating Expenses. Following the end of each calendar year, a reconciliation is made against the actual Operating Costs incurred. Sublessee's obligation to pay Sublessee's Percentage Share of Excess Operating Expenses, as set forth above in this Paragraph 5.2, shall be governed by the estimated amounts and shall be subject to any reconciliation against actual amounts, of such costs and expenses. Sublessor shall promptly deliver to Sublessee copies of all statements and notices Sublessor receives from Master Lessor regarding such Operating Expenses. Items that are specially billed by Master Lessor to Sublessor or Sublessee, rather than charged generally to office tenants by Master Lessor, shall be paid by the party requesting the specially billed item in the manner required by the Master Lease. (The Base Rent, the Furniture Rent [as defined in Paragraph 22], and Sublessee's Percentage Share of Excess Operating Expenses are hereinafter collectively referred to as "RENT"). 6. SERVICES; REPAIRS. 6.1. Provisions of Services. Notwithstanding any other provisions of this Sublease (including, without limitation, the quiet enjoyment covenant of Paragraph 2.3), the only facilities, utilities or services (collectively "SERVICES") to which Sublessee is entitled hereunder are those to which Sublessor is entitled under the Master Lease. Sublessee shall look solely to Master Lessor under the Master Lease for all such services, including, without limitation, the services to be provided by Master Lessor under Section 3.1 of the Master Lease. Notwithstanding the foregoing, Sublessor does hereby assign, transfer and set over to -4- 5 Sublessee any and all rights it has or might have against the Master Lessor under the Master Lease for all such services, including, without limitation, the services to be provided by Master Lessor under Section 3.1 of the Master Lease, to the extent that such services involved are applicable to the Subleased Premises. Sublessee shall pursue any such rights and remedies by virtue of such assignment at its own cost and expense and shall indemnify and hold harmless Sublessor from any loss, cost, claim, damages, expense, causes of action or liability (including, without limitation, attorneys' fees and costs) asserted against Sublessor by Master Lessor by reason of Sublessee's pursuit of such rights and remedies. This assignment will terminate contemporaneously with the termination of this Sublease. 6.2. No Abatement or Termination. (a) If Master Lessor shall fail to perform its covenants or furnish any of the services set forth in the Master Lease (including, without limitation, the covenants and services set forth in Section 3.1 of the Master Lease), then Sublessee shall immediately give written notice to Sublessor and to Master Lessor, specifying in as much detail as possible such failure. (b) Failure by Master Lessor to perform any covenant or furnish any of the utilities or services set forth in the Master Lease (including, without limitation, the failure to furnish any of the services specified in Section 3.1 of the Master Lease) shall not render Sublessor liable in any respect for damages to either person or property, nor be construed as an eviction by Sublessor, nor entitle Sublessee to an abatement of Rent (except that Sublessee may abate Rent and receive reimbursement of out-of-pocket expenses incurred in temporarily relocating from the Subleased Premises to the extent that Sublessor would have been entitled under Section 3.1 of the Master Lease to rental abatement and reimbursement of out-of-pocket relocation expenses on account of a services interruption to the Subleased Premises had Sublessor occupied the Subleased Premises at the time of the services interruption), nor entitle Sublessee to terminate this Sublease in whole or in part (except that Sublessee may terminate this Sublease if [i] Sublessor has the right to terminate the Master Lease on account of the services interruption to the Subleased Premises, but fails to do so, or [ii] a Basic Services Failure [as defined in the Master Lease] which is not the result of an Unavoidable Interruption [as defined in the Master Lease] continues for 180 consecutive days or more, and such Basic Services Failure affects 25% or more of the Subleased Premises and it becomes reasonably impracticable for Sublessee to operate in the Subleased Premises such that Sublessee must relocate to other premises), nor relieve Sublessee from fulfillment of any covenant or agreement hereunder, and Sublessee shall have no claim of set-off or rebate of Rent (except as expressly provided in this Paragraph 6.2) or damages on account of any interruption in services occasioned thereby or resulting therefrom. -5- 6 6.3. Repairs. Sublessee shall maintain the Subleased Premises in the same or better condition than the condition in which the Subleased Premises existed on the Commencement Date (reasonable wear and tear excluded). Notwithstanding any other provisions of this Sublease (including, without limitation, the quiet enjoyment covenant of Paragraph 2.3), the only repairs and maintenance to which Sublessee is entitled hereunder are those to which Sublessor is entitled under the Master Lease. Sublessee shall look solely to Master Lessor under the Master Lease for all such repairs and maintenance, including, without limitation, the repairs and maintenance to be provided by Master Lessor under Section 5.4 of the Master Lease. Sublessor shall have no obligation to perform or make any such repairs or maintenance with respect to the Subleased Premises. Sublessee agrees, at its sole cost and expense, to perform all repairs to and maintenance of the Subleased Premises required by Sublessor as tenant under the Master Lease, including, without limitation, those described in Section 5.5 of the Master Lease. Notwithstanding the foregoing, Sublessor does hereby assign, transfer and set over to Sublessee any and all rights it has or might have against the Master Lessor under the Master Lease for all repairs and maintenance to be provided by Master Lessor under Section 5.4 of the Master Lease, to the extent that such repairs involved are applicable to the Subleased Premises. Sublessee shall pursue any such rights and remedies by virtue of such assignment at its own cost and expense and shall indemnify and hold harmless Sublessor from any loss, cost, claim, damages, expense, cause of action or liability (including, without limitation, attorneys, fees and costs) asserted against Sublessor by Master Lessor by reason of Sublessee's pursuit of such rights and remedies. This assignment will terminate contemporaneously with the termination of this Sublease. 7. USE OF SUBLEASED PREMISES. The Subleased Premises shall be used by Sublessee solely as business offices and the incidental uses of preparing and serving meals for Sublessee's employees and invitees, subject, however, to Legal Requirements (as defined in the Master Lease) and Sublessor's approval, which approval shall not be unreasonably withheld, as to (A) the condition of any lunchroom equipment, (B) the visibility of such equipment from outside the Subleased Premises, and (C) the location, layout, design, visibility and venting of such equipment. 8. INCORPORATION OF MASTER LEASE. 8.1. Compliance with Master Lease. Except (i) to the extent that the provisions of the Master Lease are in clear conflict with the terms and provisions of this Sublease, and (ii) as expressly otherwise provided in this Sublease (including, without limitation, Paragraph 17 hereof), Sublessee shall comply with all of the provisions of the Master Lease that are to be observed or performed during the term hereof by Sublessor as tenant thereunder with respect to the Subleased Premises.

Subject to the preceding sentence, Sublessee shall be bound by all the provisions of the Master Lease pertaining to the Subleased Premises and shall perform all of the obligations and responsibilities that Sublessor is obligated to perform pursuant to the Master Lease pertaining to the Subleased Premises. Therefore, for the purposes of this Sublease, wherever in the Master Lease the word "LANDLORD" is used, it shall mean Sublessor and wherever in the Master Lease the word "TENANT" is used, it shall mean Sublessee and wherever in the Master Lease the word "LEASED PREMISES" or similar words are used, they shall mean the Subleased Premises; all terms not specifically defined herein shall have the same meanings designated thereto in the Master Lease provided that the same is not in conflict with the terms and provisions of this Sublease. (b) Notwithstanding Paragraph 8.2(a), this Sublease shall not and does not create any rights in Master Lessor or any third parties. 8.3. Subleased Premises. The parties acknowledge and agree that Sublessee's rights and obligations hereunder relate to only those portions of the Leased Premises covered by the Master Lease that are a part of, or are related or appurtenant to, the Subleased Premises. 8.4. Subject to Master Lease. This Sublease is expressly subject to and inferior to the Master Lease, and no provision of this Sublease shall be construed in a manner that would violate the terms of the Master Lease. Sublessor may from time to time hereafter amend the Master Lease, in which case the term "MASTER LEASE", as used herein, shall include any and all amendments to the First Amended and Restated Lease Agreement dated as of July 6, 1989; provided, however, Sublessor agrees that no amendments, changes or modifications shall be made to the Master Lease which affect Sublessee's Rent obligation under this Sublease, the term of this Sublease, the amount of space in the Subleased Premises or otherwise materially adversely affect Sublessee's rights or obligations hereunder. 8.5.

LIMITATION OF LIABILITY AND INDEMNITY. 9.1. Condition of Property. Notwithstanding any provision of this Sublease or the Master Lease to the contrary, Sublessor shall not be liable to Sublessee or any of its officers, directors, shareholders, agents, employees, servants, or invitees for any death or injury to any person or persons or for damage to property due to the conduct of Sublessee's business in the Subleased Premises, the condition or design of or any defect in the Subleased Premises, the Building, the Project, or any part or component thereof (including, without limitation, any mechanical, electrical, plumbing, heating, air conditioning or other systems or equipment), which may exist or subsequently occur, except to the extent of Sublessor's own gross negligence or willful misconduct but such exception shall be subject to the waiver of liability provisions and waiver of subrogation provisions of Sections 6.6 and 6.7 of the Master Lease, which are incorporated herein pursuant to Paragraph 8 hereof. 9.2. Acts of Sublessee. Without limiting Sublessee's other obligations under this Sublease (including, without limitation, the indemnification obligations set forth in Paragraphs 6.1, 6.3, 12.1, 20, 21, 23 and 24.15), Sublessee agrees that it will indemnify, defend and hold Sublessor harmless from and against any and all liability, loss, cost, damage or expense (including, without limitation, attorneys' fees and costs and any liability Sublessor may have to Master Lessor) arising out of or related to any act or omission of Sublessee, or any of Sublessee's officers, shareholders, directors, agents, employees, servants or invitees arising from Sublessee's use of the Subleased Premises or from any activity, work or other thing done, permitted or suffered by Sublessee or any of Sublessee's officers, shareholders, directors, agents, employees, servants or invitees on or about the Complex (as defined in the Master Lease), and Sublessee shall further indemnify and hold harmless Sublessor from and against any and all claims arising from any breach or default in the performance of any obligation on Sublessee's part to be performed under the terms of this Sublease. 9.3.

Casualty. (a) In the event of a fire or other casualty in the Subleased Premises, Sublessee shall immediately give written notice thereof to Sublessor and to Master Lessor. (b) If the Subleased Premises shall be partially destroyed by fire or other casualty not caused by Sublessee or its agents, employees or invitees so as to render the Subleased Premises untenantable, in whole or in part, and if the Master Lease is not terminated as therein provided, then the Rent shall abate thereafter as to the portion of the Subleased Premises rendered untenantable to the extent that the rent payable under the Master Lease is abated as a result of such casualty, until such time as Master Lessor has restored the Subleased Premises to permit Sublessee's re-occupancy of the Subleased Premises. Sublessee shall pay all costs with respect to any such restoration of the Subleased Premises that are required to be paid by Sublessor to Master Lessor under the Master Lease. (c) In the event of damage or destruction to the Subleased Premises, the Leased Premises, the Building or the Project, or any portions thereof, and the Master Lease is terminated as therein provided, then all accrued and unpaid Rent for the period prior to such destruction shall be paid by Sublessee and thenceforth this Sublease and the obligations of the parties hereunder shall cease and come to an end, except for any continuing obligations the parties may have to each other (including, without limitation, liability under any indemnities provided for in this Sublease).

Sublessor and Sublessee -9- 10 expressly agree that there are and shall be no implied or express warranties of merchantability, habitability, suitability, fitness for a particular purpose or any other kind arising out of this Sublease, and there are no warranties, whether written, oral, express or implied, which extend beyond those expressly set forth in this Sublease. 12. ALTERATIONS, ADDITIONS AND IMPROVEMENTS. 12.1. Consent. Sublessee shall not make any alterations, additions or improvements to the Subleased Premises without first obtaining the written consent of Sublessor (which consent shall not be unreasonably withheld) and the consent of Master Lessor. Any alterations, additions and improvements will be of a quality substantially equivalent to or better than the quality of improvements within the Subleased Premises as of the Commencement Date; provided, however, any alterations, additions and improvements to the 22nd floor may or may not be of the same quality as the existing improvements in the 22nd floor, but they will be of a quality substantially equivalent to or better than the quality of improvements within the remainder of Subleased Premises as of the Commencement Date. Sublessee shall procure any and all insurance required by Sublessor and Master Lessor to be maintained during the construction of the alterations, additions and improvements. Construction of any alterations, additions or improvements shall be performed by a general construction contractor approved by Master Lessor and Sublessor. Sublessee hereby assumes any and all liability for any and all injuries to or death of, any and all persons (including, without limitation, Sublessee's contractors and subcontractors and employees), and any liability for any and all damage to property caused by, or resulting from, or arising out of any act or omission of Sublessee, Sublessee's contractors and their subcontractors or employees in the performance of the alterations, additions and improvements.

All such work shall comply with all legal requirements and with the terms and provisions of the Master Lease. Nothing contained in this Sublease shall prevent Sublessee from removing all furniture, furnishings and trade fixtures owned by Sublessee and used in its business, provided they can be removed without damage to the Subleased Premises.

Sublessee agrees that certificates of insurance or certified copies of such insurance policies will be delivered to Sublessor and Master Lessor within ten days following the execution of this Sublease. All policies shall contain an endorsement requiring 30 days prior written notice from any insurer to Sublessor and Master Lessor before any change, cancellation, termination, or reduction in or of such policies. All policies shall acknowledge that they provide primary coverage with respect to the additional insureds thereunder and that such policies as are separately maintained by the additional insureds shall be excess insurance. 14. NO ASSIGNMENT OR SUB-SUBLEASE WITHOUT CONSENT. 14.1. Sublessee may not sell, assign, transfer, convey, or encumber this Sublease or any part thereof or any interest therein or relet the Subleased Premises, in whole or in part (hereinafter referred to as a "TRANSFER"), without first obtaining the written consent of Sublessor. Any attempted Transfer in violation hereof shall be null and void. Any Transfer by Sublessee shall not relieve Sublessee from any liability or obligation created by this Sublease. 14.2.

Sublessor shall deliver written notice of approval or disapproval of such proposed Transfer within ten business days after receipt of Sublessee's notice containing the information required by this Paragraph 14. If Sublessor fails to deliver such written notice within such ten-business day period, Sublessor shall be deemed to have refused to consent to such Transfer. Sublessor's consent to the proposed Transfer shall not be unreasonably withheld provided that: (a) the transferee proposes to use the Subleased Premises for a use permitted by Paragraph 7 hereof and otherwise in keeping with the character and nature of the other tenancies and subtenancies in the Building and without violating any restrictive uses; (b) the transferee is a reputable party (as determined in the sole discretion of Sublessor); (c) the transferee is not a state or federal governmental agency; (d) the transferee is not a competitor of another occupant of office space in the Building; (e) the transferee is not a tenant or subtenant or a prospective tenant or subtenant of any office space in the Complex (as defined in the Master Lease) at the time of the proposed subletting; and (f) no Event of Default exists either at the time of Sublessee's written notice to Sublessor or on the effective date of the proposed Transfer. Notwithstanding any Transfer, Sublessee may not convey to any transferee the right of first opportunity set forth in EXHIBIT "D". Sublessee shall deliver to Sublessor a copy of any final sublease or assignment agreement promptly after its execution. 14.4. If Sublessor elects to consent to a Transfer, and if the Rent due and payable by a transferee under any such permitted Transfer (or a combination of the Rent payable thereunder plus any bonus or other consideration therefor or incident thereto) in respect of the interval in question exceeds the Rent due under this Sublease allocable to the portion of the Subleased Premises covered thereby for the same interval, such excess shall belong to Sublessor. Sublessee shall hold all amounts it receives which are payable to Sublessor in trust and shall deliver such amounts to Sublessor within ten days after Sublessee's receipt thereof. 14.5. Notwithstanding anything contained in this Paragraph 14 to the contrary, Sublessee may, without the consent of Sublessor, sublease up to one floor of the Subleased Premises to, or permit the use or occupancy of up to one floor of the Subleased Premises by, Lacerte Financial, Ltd. provided that and for so long as the Lacerte Financial Ltd. continues to be substantially owned by the shareholders of Sublessee.

DEFAULT. -12- 13 15.1. Default by Sublessee. (i) If default shall be made in the payment of any sum of Rent, or of any sum other than Rent, to be paid by Sublessee under this Sublease (including, without limitation, any amounts owing by Sublessee pursuant to the Construction Agreement attached hereto as EXHIBIT "C"); or (ii) if default shall be made in the performance of any of the other covenants and conditions which Sublessee is required to observe and perform under this Sublease; or (iii) if the interest of Sublessee under this Sublease shall be levied on under execution or other legal process; or (iv) if any petition shall be filed by or against Sublessee to declare Sublessee a bankrupt or to delay, reduce or modify Sublessee's debts or obligations; or (v) if Sublessee is declared insolvent according to law or if any assignment of Sublessee's property shall be made for the benefit of creditors or if a receiver or trustee is appointed for Sublessee or its property; or (vi) if Sublessee shall vacate or abandon the Subleased Premises during the term of this Sublease; or (vii) if Sublessee shall default under any of the terms and provisions of the Master Lease which, by the terms of this Sublease, are applicable hereto; then Sublessor may treat the occurrence of any one or more of the foregoing events as a breach of this Sublease and thereupon, at Sublessor's option, Sublessor shall have any one or more of the following described remedies, in addition to all other rights and remedies provided at law or in equity: (a) Sublessor may terminate this Sublease and repossess the Subleased Premises and be entitled to recover as damages a sum of money equal to the total of (i) the cost of recovering the Subleased Premises, (ii) the accrued and unpaid Rent at the time of termination, plus interest thereon at the maximum lawful per annum rate under the laws of the State of Texas from the due date, (iii) the present value [discounted at the rate of eight percent per annum] of the balance of all Rent for the remainder of the Sublease term less the present value (discounted at the same rate) of the fair market rental value of the Subleased Premises for the same period (but only to the extent the remainder is a positive number) and (iv) any other sum of money and damages including any attorney's fees and court costs owed by Sublessee to Sublessor. (b) Sublessor may terminate Sublessee's right of possession (but not this Sublease) and may repossess the Subleased Premises by forcible entry or detainer suit or otherwise, without demand or notice of any kind to Sublessee and without terminating this Sublease, in which event Sublessor may, but shall be under no obligation to do so, relet the Subleased Premises for the account of Sublessee for such Rent and upon such terms as shall be satisfactory to Sublessor. For the purpose of such reletting, Sublessor is authorized to decorate and/or to make any repairs, changes, alterations and/or additions in or to the Subleased Premises that may be reasonably necessary to restore the Subleased Premises to a "BUILDING STANDARD" (as defined in the Master -13- 14 Lease) condition. In addition, (i) if Sublessor shall fail to relet the Subleased Premises, then Sublessee shall pay to Sublessor as damages a sum equal to the amount of all accrued and unpaid Rent and other accrued and unpaid sums provided for in this Sublease; or (ii) if the Subleased Premises are relet and a sufficient sum shall not be realized from such reletting after paying the accrued and unpaid Rent and other accrued and unpaid sums due hereunder at the time of reletting, the cost of recovering possession and of collecting rent accruing under such subletting, and all of the costs and expenses reasonably incurred in making such decorations, repairs, changes, alterations and/or additions necessary to relet the Subleased Premises (plus interest on all of the same at the maximum lawful contract rate), then Sublessee shall satisfy and pay any such deficiency upon demand therefor from time to time. Sublessee agrees that Sublessor may file suit to recover any sums falling due under the terms of this Paragraph 15.1(b) from time to time, and that no delivery to or recovery by Sublessor of any sum due Sublessor hereunder shall be any defense in any action to recover any amount of money not theretofore reduced to judgment in favor of Sublessor, nor shall such reletting be construed as an election on the part of Sublessor to terminate this Sublease unless a written notice of such intention is given to Sublessee by Sublessor. Notwithstanding any such reletting without termination, Sublessor may at any time thereafter elect to terminate this Sublease for such previous breach. (c) Sublessor may enter the Subleased Premises and cure at Sublessee's expense any default. (d) Sublessor may, but shall not be required to, use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or for the payment of any other amount which Sublessor may spend or become obligated to spend by reason of Sublessee's default, or to compensate Sublessor for any other loss or damage which Sublessor may suffer by reason of Sublessee's default, including, without limitation, costs and attorneys' fees incurred by Sublessor to recover possession of the Subleased Premises. If any portion of the Security Deposit is so used or applied, Sublessee shall, upon demand, deposit cash with Sublessor in an amount sufficient to restore the Security Deposit to its original amount, and Sublessee's failure to do so shall constitute a default hereunder by Sublessee. 15.2. No Duty to Mitigate. Sublessor shall have no duty whatsoever to mitigate its damages following an Event of Default by Sublessee, and Sublessor will not be liable in any way whatsoever for Sublessor's failure or refusal to relet the Subleased Premises or any portion thereof, or if the Subleased Premises or any portion thereof are relet, for Sublessor's failure to collect rental under such reletting, and no such refusal or failure to relet or failure -14- 15 to collect rental will release or affect Sublessee's liability under this Sublease. 15.3. Default by Sublessor. Except where the provisions of this Sublease grant Sublessee an express, exclusive remedy, or deny Sublessee a remedy, if Sublessor should fail to perform or observe any covenant, term, provision or condition of this Sublease and such default should continue beyond a period of 30 days (or such longer period as is reasonably necessary to remedy such default, provided Sublessor shall continuously and diligently pursue such remedy at all times until such default is cured) following notice thereof by Sublessee to Sublessor, then Sublessee shall have as its sole and exclusive remedy the right to commence such actions at law or in equity to which Sublessee may be entitled, including without limitation any action for specific performance or damages but expressly excluding an action to declare a termination of this Sublease. The rights of Sublessee pursuant to this Paragraph 15.2 shall be subject to any express provisions of this Sublease providing for remedies different from, or in exclusion of, the remedies above-described. In no event shall Sublessor be liable to Sublessee for consequential or special damages by reason of a failure to perform (or default) by Sublessor or Master Lessor hereunder or otherwise. 15.4. Non-Waiver. Failure of either party to declare any default immediately upon occurrence thereof, or delay in taking any action in connection therewith, shall not waive such default or right to take such action, but such party shall have the right to declare any such default or take such action at any time. Sublessor's acceptance of partial payment of any sum owing hereunder shall not constitute a waiver of or be deemed to constitute a waiver or estoppel by Sublessor of the right to collect the full amount of any sum owing hereunder. 15.5. Cumulative Remedies. All rights and remedies of Sublessor enumerated in this Sublease (including, without limitation, indemnification rights) shall be cumulative and shall not exclude any other right or remedy allowed by law. These rights and remedies may be exercised or enforced concurrently and as often as necessary. 16. EXCULPATION. Sublessee shall maintain the Subleased Premises in the same or better condition than the condition in which the Subleased Premises existed on the Commencement Date (reasonable wear and tear excluded). Sublessee acknowledges and agrees that Sublessor shall not be responsible for any maintenance, services, or repairs to the Subleased Premises, to the Building, the Project, or any part thereof, nor shall Sublessor be liable for any interruption in utilities or services to the Subleased Premises, nor for loss or damage to any person or any property of Sublessee or its employees or invitees by theft or otherwise, nor shall Sublessor be liable -15- 16 for any damage or disturbance caused by other tenants of the Building or the Project.

CONDITION OF THE SUBLEASED PREMISES During the 15-day period following notice of substantial completion of the Leasehold Improvements given to Sublessee by Sublessor, Sublessee's Representative will conduct a walk-through C-6 42 inspection of the Subleased Premises with Sublessor's Representative and prepare a punch-list of items needing additional work by Sublessor. Other than the items specified in the punchlist and subject to latent defects discovered by Sublessee and Sublessor within the first twelve (12) months after the Commencement Date, by taking possession of the Subleased Premises Sublessee will be deemed to have accepted the Subleased Premises in their "as is" condition on the date of delivery of possession and to have acknowledged that Sublessor has installed the Leasehold Improvements as required by this Construction Agreement in accordance with the Final Plans, and that there are no items needing additional work or repair. Provided, however, the punchlist will not include any damage to the Subleased Premises caused by Sublessee's move-in or early access. Damage caused by Sublessee will be repaired or corrected by Sublessor at Sublessee's expense. Sublessee acknowledges that neither Sublessor nor its agents or employees have made any representations or warranties as to the suitability or fitness of the Subleased Premises for the conduct of Sublessee's contemplated use or for any other purpose, nor has Sublessor or its agents or employees agreed to undertake any alterations or construct any improvements to the Subleased Premises except as expressly provided in the Sublease and this Construction Agreement. If Sublessee fails to submit a punch-list to Sublessor within 30 days of the date of the walk-through inspection, it will be deemed that there are no items needing additional work or repair. Sublessor's contractor will complete all reasonable punchlist items as soon as reasonably practicable after receiving Sublessee's punch-list. 8. SUBLESSOR DELAYS If Sublessor shall be delayed in substantially completing the Leasehold Improvements as a result of: 8.1 Delays by Sublessor in approving the Preliminary Space Plan, Initial Plans and Specifications or Final Plans, or 8.2 Delays attributable to the failure of Sublessor to allow the Approved Contractor and/or subcontractors and/or materialmen access to the Subleased Premises, 8.3 Delays attributable to the failure of Sublessor to vacate and deliver the Phase I and Phase II Premises by the Phase I and Phase II Delivery Dates, respectively, then, Sublessee's obligation for payment of Rent under the Sublease shall be delayed by the number of days of such delay. 9. MASTER LESSOR'S APPROVALS Notwithstanding anything contained in this Construction Agreement to the contrary, if Sublessor determines that the consent C-7 43 or approval of Master Lessor is required for any matter pertaining to the construction of the Leasehold Improvements (including, without limitation, approval of the Preliminary Space Plan, Initial Plans and Specifications, Final Plans, Qualified Contractors, or any subcontractors), then the procedure set forth in this Construction Agreement for approving the design of the Leased Premises and completing the construction of the Leasehold Improvements shall in all events be subject and subordinate to obtaining the consent or approval of Master Lessor.

The ROFO shall not be applicable during any time when there is an uncured event of default under the Sublease. 3. EXERCISE OF ROFO. If a ROFO Floor in the Building becomes available, availability, for purposes hereof, to be at the sole determination of Sublessor, Sublessor shall so notify Sublessee. (a) Sublessee shall have five days from the receipt of such notice to notify Sublessor in writing of the exercise by Sublessee of Sublessee's ROFO with respect to all, but not less than all, of the ROFO Floor, which shall be on the same terms and conditions as this Sublease except that if the ROFO is exercised during the period commencing on the day following the second anniversary of the Commencement Date and continuing through October 31, 1999 the Base Rent for the ROFO Floor shall be $15.35 per square foot of Net Rentable Area in the ROFO Floor. (b) If Sublessee fails to so notify Sublessor within such five-day period referenced in subparagraph (a) above, Sublessee shall be deemed to have irrevocably waived its ROFO with respect to the subject ROFO Floor, and this Exhibit shall thereafter be of no further force or effect with respect to such floor of the Building. If Sublessee elects to exercise its ROFO with respect to any ROFO Floor and does in fact exercise such ROFO in the manner and within the time period specified herein, Sublessor and Sublessee shall, within 30 days after Sublessee delivers to Sublessor notice of its D-1 45 election, enter into a written amendment modifying and supplementing the Sublease in the manner required by subparagraph (a) above. If Sublessee fails to enter into said amendment within such 30-day period, Sublessee shall be deemed to have irrevocably waived its ROFO with respect to the subject ROFO Floor, and this Exhibit shall thereafter be of no further force or effect with respect to such floor of the Building. Except as may be specifically modified in such amendment the terms and provisions of the Sublease shall, on the day of delivery of the ROFO Floor to Sublessee, automatically apply and become applicable to the ROFO Floor; and the ROFO Floor, as of the date of such delivery, shall automatically and without the necessity of further documentation, become and be deemed to be a part of the Subleased Premises.

DELIVERY OF ROFO FLOOR. Any ROFO Floor shall be delivered to Sublessee vacant and unoccupied and "as is" without benefit of improvements. Sublessor shall use reasonable diligence to deliver the ROFO Floor on the date specified in Sublessor's notice of its availability, but in no event shall Sublessor have any liability for the failure to deliver the ROFO Floor to Sublessee on such date, nor shall any such failure impair the validity of the Sublease, extend the Sublease term, or impair any obligations of Sublessee under the Sublease, it being understood that the Rent applicable to the ROFO Floor shall be abated until possession is delivered to Sublessee in full settlement of all claims that Sublessee might otherwise have against Sublessor by reason of the failure to deliver possession of the ROFO Floor to Sublessee. 5. TERMINATION OF ROFO. The ROFO shall automatically terminate upon (a) the termination of the Sublease term, whether by Sublessor upon the occurrence of an event of default or otherwise, (b) the failure of Sublessee to exercise the ROFO as and within the time period specified in Paragraph 3 above, but only with respect to the subject ROFO Floor, (c) Sublessee's election to lease the ROFO Floor (it being understood that the ROFO applies only to one floor in the Building and terminates upon Sublessee's subleasing of any such floor) , and (d) upon the assignment, subletting, or other transfer by sublessee, whether or not with the approval of Sublessor, other than any sublease to Lacerte Financial, Ltd. pursuant to Paragraph 14.5 of the Sublease.

Failure of Sublessor to insist upon strict performance or observance of any of the terms, provisions or covenants of the Sublease or to exercise any right therein contained shall not be construed as a waiver or relinquishment for the future of any such term, provision, covenant or right, but the same shall continue and E-1 47 remain in full force and effect. Receipt by Sublessor of rent (or any other monetary sum or acceptance of performance of any obligation of Sublessee under the Sublease) with knowledge of the breach of any provision of the Sublease shall not be deemed a waiver of such breach.

Guarantor further agrees that in any right of action which shall accrue to Sublessor under the Sublease, Sublessor may, at its option, proceed against Sublessee alone (without having made any prior demand upon Guarantor or having commenced any action against Guarantor of having obtained or having attempted to satisfy any judgment against Guarantor) or may proceed against Guarantor and Sublessee, jointly or severally, or may proceed against Guarantor alone (without having made any prior demand upon Sublessee or having commenced any action against Sublessee or having obtained or having attempted to satisfy any judgment against Sublessee) or, in the case of there being more than one Guarantor, may proceed against one or more Guarantors (without having made any prior demand upon any other Guarantor or having commenced any action against any other Guarantor or having obtained or attempted to satisfy any judgment against any other Guarantor). 5. Guarantor further covenants and agrees that if the Sublease terminates and Sublessor has any rights it can enforce against Sublessee after termination, Sublessor may enforce those rights against Guarantor without prior notice to or demand upon Sublessee. 6. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA. 7. Guarantor specifically waives any notice of acceptance of this Guaranty by Sublessor. 8. If any obligation of Sublessee under the Sublease is secured, in whole or in part, by collateral of any type Sublessor may, from time to time, at its discretion and with or without valuable consideration, allow substitution or withdrawal of all or any part of such collateral or subordinate or waive any of its lien rights with respect to all or any part of such collateral or release all or any part of such collateral, without notice to or consent of Guarantor and without in any way impairing, diminishing or releasing the liability of Guarantor under this Guaranty. Under no circumstances shall Sublessor be required to first resort to any collateral for any obligation of Sublessee as any nature of prerequisite or precondition to invoking or enforcing the liability of Guarantor under this Guaranty.

Guarantor further acknowledges and agrees that but for the execution and delivery of this Guaranty by Guarantor, Sublessor would not have executed and delivered the Sublease. 10. Guarantor agrees that in the event that Sublessee shall become insolvent or shall be adjudicated a bankrupt, or shall file petition for reorganization, rearrangement or other relief under any present or future provisions of the Federal Bankruptcy Code, or if such a petition be filed by creditors of Sublessee, or if Sublessee shall seek a judicial readjustment of the rights of its creditors under any present or future Federal or state law or if a receiver of all or part of its property and assets is appointed by any State or Federal court, no such proceeding or action taken therein shall modify, diminish or in any way affect the liability of Guarantor under this Guaranty and the liability of Guarantor with respect to the Sublease shall be of the same scope as if Guarantor had executed the Sublease as the named subtenant thereunder. No rejection or termination of the Sublease in any of the proceedings referred to in this paragraph shall be effective to release or terminate the continuing liability of Guarantor to Sublessor under this Guaranty with respect to the Sublease for the remainder of the Sublease term stated therein unaffected by any such rejection or termination in said proceedings. 11. All rights of Guarantor against Sublessee arising by way of subrogation on account of Guarantor's having performed some covenant, duty or obligation of Sublessee under the Sublease shall be subject and subordinate to all of the rights of Sublessor against Sublessee with respect to the Sublease. Guarantor shall not exercise any such right of Guarantor against Sublessee until all of the covenants, duties and obligations of Sublessee under the Sublease shall have been fully performed. 12. The stated rights of Sublessor under this Guaranty shall be understood as not excluding any other legal or equitable rights of Sublessor against Guarantor not expressly set forth herein, but shall be understood as being cumulative to all such other legal and equitable rights of Sublessor not expressly stated herein. 13.

E-3 49 14. Should any portion of this Guaranty ever be held legally invalid or unenforceable, the balance of this Guaranty shall not thereby be affected, but shall remain in full force and effect in accordance with its terms and provisions. 15. All terms and provisions hereof shall inure to the benefit of the assigns and successors of Sublessor and shall be binding upon the heirs, executors, administrators, successors and assigns of Guarantor. 16. In any action between the parties seeking enforcement or interpretation of this Guaranty or the Sublease, the prevailing party in such action shall be awarded, in addition to damages, injunctive or other relief, its reasonable cost and expenses, and a reasonable attorneys' fee as may be fixed by the court having jurisdiction over the matter. 17. This Guaranty was reviewed by Guarantor, and Guarantor acknowledges and agrees that Guarantor (a) understands fully all of the terms of this Guaranty and the consequences and implications of 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 such other persons as Guarantor may have desired. 18.
