                                      -5-
<PAGE>   5

       assessment shall be so changed that the whole or any part of the taxes,
       assessments, levies, impositions or charges now levied, assessed or
       imposed on real estate and the improvements thereto shall be discontinued
       and as a substitute therefor, or in lieu of an addition thereto, taxes,
       assessments, levies, impositions or charges shall be levied, assessed
       and/or imposed wholly or partially as a capital levy or otherwise on the
       rents received from the Project or the rents reserved herein or any part
       thereof, then such substitute or additional taxes, assessments, levies,
       impositions or charges, to the extent so levied, assessed or imposed,
       shall be deemed to be included within Operating Expenses to the extent
       that such substitute or additional tax would be payable if the Project
       were the only property of the Landlord subject to such tax. It is agreed
       that Tenant will be responsible for ad valorem taxes on its personal
       property and on the value of the leasehold improvements in the Premises
       to the extent that the same exceed Building standard allowances (and if
       the taxing authorities do not separately assess Tenant's leasehold
       improvements, Landlord may make a reasonable allocation of the ad valorem
       taxes assessed on the Project to give effect to this sentence).

Operating Expenses shall not include:

(a)    depreciation on the Project or any Common Areas, except for amortization
       charges related to the capital improvements set forth in Paragraph
       2.3(b);

                     (either by an insurer, condemnor or other person or
                     entity), but only to the extent of such reimbursement, and
                     any and all expenses for which Landlord is reimbursed or
                     entitled to reimbursement by a tenant in the Project
                     pursuant to a lease provision in such tenant's lease;

              (d)    salaries for personnel above the grade of senior property
                     manager, senior controller, senior accountant and senior
                     engineer;

              (e)    costs in connection with services or benefits of a type

              (f)    Landlord's general overhead and administrative expenses not
                     directly allocable to the operation of the Project.

              below, Base Rent in the amount specified in Paragraph 1.6 above
              payable in advance on the Commencement Date and on or before the
              first day of each and every successive calendar month during the
              term hereof without demand, setoff or deduction. Tenant agrees to
              pay to Landlord contemporaneously with the execution of this
              Lease, the amount of $60,673.83 which amount shall be applied to
              August 1998 Base Rent.

       5.2    Late Charge: All rent shall bear interest from the date due until
              paid at the greater of (1) two percent (2%) above the "prime rate"
              per annum of Chase Texas or its successor ("Chase") in effect on
              said due date (or if the "prime rate" be discontinued, the base
              reference rate then being used by Chase to define the rate of
              interest charged to commercial borrowers) or (2) eighteen percent
              (18%) per annum; provided, however,


                                      -8-
<PAGE>   8

              in no event shall the rate of interest hereunder exceed the
              maximum non-usurious rate of interest (hereinafter called the
              "Maximum Rate") permitted by the applicable laws of the State of
              Texas or the United States of America, whichever shall permit the
              higher non-usurious rate, and as to which Tenant could not
              successfully assert a claim or defense of usury, and to the extent
              that the Maximum Rate is determined by reference to the laws of
              the State of Texas, the Maximum Rate shall be the weekly ceiling
              (as defined and described in Chapter 303 of the Texas Finance
              Code, as amended) at the applicable time in effect. Twice per
              annum, Landlord shall provide Tenant with a gracious period of
              three (3) days if Tenant is late paying its rent.

6.     OPERATING EXPENSES:

       6.1    Operating Expenses Rent: In addition to Base Rent, Tenant shall
              pay Tenant's Percentage Share, as specified in Paragraph 1.3
              above, of the Operating Expenses paid or incurred by Landlord in
              such year in excess of the Operating Expenses for the Base Year
              ("Operating Expenses Rent"). All sums of money as shall become
              due and payable by Tenant to Landlord under this Lease, including,
              without limitation, Operating Expenses Rent shall be additional
              rent which Tenant shall be obligated to pay. Landlord shall have
              the same remedies for default in the payment of additional rent as
              are available to Landlord in the case of a default in the payment
              of Base Rent.

       6.2    Controllable Expenses: Notwithstanding anything in this Lease to
              the contrary, Landlord agrees, for purposes of computing Tenant's
              Operating Expenses Rent, that any increase in total Controllable
              Expenses in excess of ten percent (10%) in any given calendar year
              shall be excluded in such computation. For purposes of this
              Paragraph 6.2, Landlord and Tenant acknowledge and agree that
              "Controllable Expenses" are defined as all Operating Expenses
              except the following: (i) utilities, (ii) property taxes, (iii)
              insurance and (iv) those items affected by labor costs, such as
              janitorial services, in the event of an increase in the legal
              minimum wage or a general increase in the wage level in the
              Houston, Texas area.

       6.3    Payment: During December of each calendar year or as soon
              thereafter as practicable, Landlord will give Tenant written
              notice of its estimate (line item and detailed support included)
              of Operating Expenses Rent for the ensuing calendar year. On or
              before the first day of each month during the ensuing calendar
              year, Tenant will pay to Landlord 1/12th of such estimated
              amounts, provided that if such notice is not given in December,
              Tenant will continue to pay on the basis of the prior year's
              estimate until the month after such notice is given. If at any
              time or times it appears to Landlord that the amounts payable for
              Operating Expenses Rent for the current calendar year will vary
              from its estimate by more than 10%, Landlord, by written notice to
              Tenant, will revise its estimate for such year, and subsequent
              payments by Tenant for such year will be in an amount so that by
              the end of such year Tenant will have paid a total sum equal


                                      -9-
<PAGE>   9

              to such revised estimate. Landlord will indicate in its notice to
              Tenant the reasons Landlord believes its estimate varies by more
              than 10%.

       6.4    Statement: Within 120 days after the close of each calendar year
              or as soon after such 120 day period as practicable, Landlord will
              deliver to Tenant a statement of amounts of Operating Expenses
              Rent payable under this Lease for such calendar year. If such
              statement shows an amount owing by Tenant that is more than the
              estimated payments for such calendar year previously made by
              Tenant, Tenant will pay the deficiency to Landlord within 30 days
              after delivery of the statement to Tenant. If the statement shows
              an amount which is less than the estimated payments previously
              paid by Tenant for the calendar year, provided Tenant is not then
              in default, Landlord will remit the amount owed Tenant within 30
              days after delivery of the statement to Tenant. Tenant has the
              right, exercisable no more than once each calendar year on
              reasonable notice and at a time reasonably acceptable to Landlord,
              to cause an audit to be performed of Landlord's operations and/or
              books and records pertaining to Operating Expenses for the
              preceding 2 calendar years. Landlord, at Landlord's sole
              discretion, may provide an audit prepared by a certified public
              accountant in lieu of allowing Tenant to audit Landlord's
              operations and/or books. Any such inspection and audit shall be at
              Tenant's expense and shall be conducted in Landlord's office
              during normal business hours by Tenant's accounting personnel or
              by independent public accountants or other qualified consultants
              and in no event will Landlord be obligated to permit any such
              inspection or audit to be performed by a consultant or firm that
              is compensated on a contingent fee or percentage of recovery
              basis.

       6.5    Proration: If for any reason other than the default of Tenant,
              this Lease terminates on a day other than the last day of a
              calendar year, the amount of Operating Expenses Rent payable by
              Tenant applicable to the calendar year in which such termination
              occurs will be prorated on the basis which the number of days from
              the commencement of such calendar year to and including such
              termination date bears to 365.

       6.6    Computation: Tenant's Percentage Share of the Operating Expenses
              is the proportion that the Net Rentable Area occupied by Tenant
              bears to the Net Rentable Area of the Building, as determined by
              Landlord. Notwithstanding any provision of this Paragraph 6.5 to
              the contrary, if the Building is less than ninety-five percent
              (95%) leased and/or occupied during any calendar year, an
              adjustment shall be made in computing each component of the
              Operating Expenses that varies with the rate of occupancy of the
              Building (such as, but not limited to, utility and janitorial
              expenses) so that Operating Expenses Rent shall be computed for
              such year as though 95% of the Building had been leased and
              occupied during such year.

       6.7    Taxes Payable by Tenant: Tenant shall be directly responsible for
              taxes upon, measured, by or reasonably attributable to the cost or
              value of Tenant's equipment, furniture, fixtures and other 
              personal property located in the Premises or by the cost or


                                      -10-
<PAGE>   10
              value of any leasehold improvements made in or to the Premises by
              or for Tenant other than the initial improvements to be installed
              at Landlord's expense regardless of whether title to such
              improvements is in Tenant or Landlord,

    7.   USE OF PREMISES:

         7.1  Effect on Insurance: Tenant shall not use any portion of the
              Premises for purposes other than those specified in Paragraph 1.8
              and no use shall be made or permitted to be made upon the
              Premises, nor acts done, which will increase the existing rate of
              insurance upon the Project, or cause cancellation of insurance
              policies covering said Project.

         7.2  Continuous Operation: Tenant will not leave the Premises
              unoccupied or vacant and will continuously conduct and carry on in
              the Premises the type of business for which the Premises are
              leased.

         7.3  Miscellaneous Restrictions: Tenant will operate from the Premises
              using the Trade Name set forth in Paragraph 1.9. Tenant will not
              use the Premises for or permit in the Premises any offensive,
              noisy, or dangerous trade, business, manufacture or occupation or
              interfere with the business of any other tenant in the Project.
              Tenant agrees not to cause, permit or suffer any waste or damage,
              disfigurement or injury to the Premises or the fixtures or
              equipment thereof or the Common Areas. Tenant will not use the
              Premises for washing clothes or cooking and nothing will be
              prepared, manufactured or mixed in the Premises which might emit
              any offensive odor into the Project. Tenant will not obstruct the
              sidewalks, mall or Common Areas in the Project or use the same for
              business operations or advertising. Tenant will not use the
              Premises for any purpose which would create unreasonable elevator
              loads, cause structural loads to be exceeded or adversely affect
              the mechanical, electrical, plumbing or other base building
              systems. Tenant will at all times comply with the rules and
              regulations of the Project attached hereto as Schedule 5, and with
              such additional rules and regulations as may be adopted by
              Landlord from time to time.

    8.  PARKING: Parking spaces for the Premises shall be governed by the terms
        and provisions of Schedule 6 attached hereto and made a part hereof for
        all purposes.

    9.  GRAPHICS: Landlord, at Tenant's sole cost and expense, will install and
        maintain all letters or numerals on the entrance doors for the Premises.
        All such letters and numerals shall be in the form specified by
        Landlord, and no other shall be used or permitted on the Premises.
        Tenant shall not place any signs within the Premises which are visible
        from the outside the Premises without Landlord's prior written approval.
        In addition, Landlord agrees that it will maintain Tenant's name
        identity (in size, graphic style and material approved by Landlord in
        its reasonable discretion and the purchase and installation of Tenant's
        signage to be borne by Tenant) on the monument sign constructed by
        Landlord at the street level entrance to the

                                      -11-

<PAGE>   11


        Building on Post Oak Boulevard. Tenant's name shall appear on the upper
        half of the monument sign above the street address. Tenant's name will
        be one of two names to appear on the upper half of the sign. If, as of
        October 1, 1998, Tenant is the largest Tenant to have signed a Lease for
        Lease Space for the Building, Tenant's name will appear first on the
        monument sign.

10.     ASSIGNMENT AND SUBLETTING; ENCUMBRANCE: Tenant shall not assign this
        Lease or sublet any portion of the Premises without prior written
        consent of the Landlord, which will not be unreasonably withheld or
        delayed, it being understood that it shall be reasonable for Landlord,
        among other things, to withhold consent if Landlord is not satisfied
        with the financial responsibility, identity, reputation or business
        character of the proposed assignee or sublessee. Any change in the
        ownership of Tenant, if Tenant is a corporation or partnership, shall
        constitute an assignment for purposes of this Paragraph 10.
        Notwithstanding any consent by Landlord, Tenant and Guarantor(s), if
        any, shall remain jointly and severally liable (along with each approved
        assignee and sublessee, which shall automatically become liable for all
        obligations of Tenant hereunder with respect to that portion of the
        Premises so transferred), and Landlord shall be permitted to enforce the
        provisions of this Lease directly against Tenant or any assignee or
        sublessee without proceeding in any way against any other party. In the
        event of an assignment, contemporaneously with the granting of
        Landlord's consent, Tenant shall cause the assignee to expressly assume
        in writing and agree to perform all of the covenants, duties and
        obligations of Tenant hereunder and such assignee shall be jointly and
        severally liable therefore along with Tenant. No usage of the Premises
        different from the usage provided for in Paragraph 1.8 above shall be
        permitted, and all other terms and provisions of the Lease shall
        continue to apply after such assignment or sublease. Tenant shall not
        make or consent to any conditional, contingent or deferred assignment of
        some or all of Tenant's interest in this Lease without the prior written
        consent of Landlord, which Landlord may withhold in its sole and
        absolute discretion. Tenant shall not enter into, execute or deliver any
        financing or security agreement that can be given priority over any
        mortgage given by Landlord or its successors, and, in the event Tenant
        does so execute or deliver such financing or security agreement, such
        action on the part of Tenant shall be considered a breach of the terms
        and conditions of this Lease and a default by Tenant entitling Landlord
        to such remedies as are provided for in this Lease. Landlord shall have
        the right to freely assign or transfer, in whole or in part, Landlord's
        rights and obligations hereunder and in the Project and the Premises.
        The prohibition against an assignment or sublease described in this
        Section 10 shall be deemed to include a prohibition against Tenant's
        mortgaging or otherwise encumbering its leasehold estate, as well as
        against an assignment or sublease which may occur by operation of law,
        each of which shall be ineffective and void and shall constitute an
        event of default under this Lease unless consented to by Landlord in
        writing in advance.

11.     ORDINANCES AND STATUTES: From and after the Commencement Date, at
        Tenant's sole cost, Tenant will comply with all statutes, ordinances and
        requirements of all municipal, state and federal authorities now in
        force, or which may hereafter be in force, pertaining to the Premises,
        occasioned by or affecting the use thereof by Tenant. In addition,
        Tenant shall be


                                      -12-

<PAGE>   12


        wholly responsible for any accommodations or alterations that are
        required by applicable governmental codes, ordinances, rules,
        regulations and laws to be made to the Premises from and after the
        Commencement Date to accommodate disabled employees and customers of
        Tenant, including, without limitation, compliance with the American with
        Disabilities Act (42 U.S.C. Sections 1201 et seq.) ("ADA") and the Texas
        Architectural Barriers Act (Tex.Rev.Civ.Stat. Art 9201) ("TABA"). The
        commencement or pendency of any state or federal court abatement
        proceeding affecting the use of the Premises shall, at the option of the
        Landlord, be deemed a breach thereof.

12.     MAINTENANCE, REPAIRS, ALTERATIONS:

        12.1   Tenant's Obligations: Tenant acknowledges that to the best of its
               knowledge the Premises are in good order and repair, unless
               otherwise indicated herein, Tenant shall, at its own expense and
               at all times, maintain the Premises in good and safe condition
               and shall surrender the same, at termination hereof, in as good
               condition as received, normal wear and tear excepted. Tenant, at
               Tenant's expense, shall be responsible for all repairs required,
               excepting the electrical wiring, plumbing and HVAC installations
               and any other system or equipment upon the Premises, roof,
               exterior walls, structural foundations, parking areas and other
               Common Areas, which shall be repaired by Landlord and included in
               Operating Expenses.

        12.2   Limits an Alteration: Tenant may not make any structural
               improvement or alteration to the Premises without the prior
               written consent of Landlord. Tenant may not make an nonstructural
               improvement or alteration of the Premises costing in excess of
               $5,000 without the prior written consent of the Landlord. Prior
               to the commencement of any repair, improvement, or alteration,
               Tenant shall give Landlord at least 2 days written notice in
               order that Landlord may post appropriate notices to avoid any
               liability for liens. All alterations will be made by a licensed
               contractor consented to by Landlord and performed in a good and
               workmanlike manner as well as in accordance with all applicable
               governmental codes, ordinances, rules, regulations and laws. All
               materials shall be of a quality comparable to or better than
               those in the Premises and shall be in accordance with plans and
               specifications approved by Landlord.

        12.3   Liens: Tenant will pay all costs of construction done by it or
               caused to be done by it on the Premises as permitted by this
               Lease, Tenant will keep the Project free and clear of all
               construction, mechanic's, materialman's, laborer's and supplier's
               liens, resulting from construction done by or for Tenant. The
               interest of Landlord in the Premises and the Project shall not be
               subject to liens for improvements made by Tenant. Any lien filed
               by any contractor, materialman, laborer or supplier performing
               work for Tenant shall attach only to Tenant's interest in the
               Premises. Tenant agrees to indemnify, defend and hold harmless
               Landlord from and against any and all costs and liabilities and
               any and all mechanic's, materialman's or laborer's liens arising
               out of or pertaining to any improvements or construction done by
               Tenant. All persons and entities


                                      -13-


<PAGE>   13


               contracting or otherwise dealing with Tenant relative to the
               Premises or the Project are hereby placed on notice of the
               provisions of this Paragraph 12.3, and Tenant shall further
               notify in writing such persons or entities of the provisions of
               this Paragraph 12.3 prior to commencement of any Tenant work in
               the Premises. If any construction, mechanic's, materialman's or
               laborer's lien is ever claimed, fixed or asserted against the
               Premises or any other portion of the Project in connection with
               any such Tenant work, Tenant shall, within 10 days after receipt
               by Tenant of notice of such lien, discharge same as a lien either
               by payment or by posting of any bond as permitted by law. If
               Tenant shall fail to discharge any such lien, whether valid or
               not, within 10 days after receipt of notice from Landlord,
               Landlord shall have the right, but not the obligation, to
               discharge such lien on behalf of Tenant and all costs and
               expenses incurred by Landlord associated with the discharge of
               the lien, including without limitation, attorneys' fees, shall
               constitute additional rent hereunder and shall be immediately due
               and payable by Tenant.

        12.4   Surrender of Premises: On the last day of the term hereof or on
               any sooner termination, Tenant shall surrender the Premises to
               Landlord in the same condition as when received, ordinary wear
               and tear excepted, clear and free of debris. Tenant shall repair
               any damage to the Premises occasioned by the installation or
               removal of Tenant's trade fixtures, furnishings and equipment.

13.     ENTRY AND INSPECTION: Tenant shall permit Landlord or Landlord's agents
        to enter upon the Premises at reasonable times and upon reasonable
        notice for the purpose of inspecting the same, performing any services
        required of Landlord hereunder and showing the Premises to potential and
        existing mortgagees and purchasers and prospective tenants of other
        space in the Project. The foregoing notwithstanding, Landlord is not
        required to give notice to Tenant if Landlord must enter the Premises
        because of an emergency. Upon reasonable notice to Tenant, Tenant will

15.     POSSESSION: If Landlord is unable to deliver possession of the Premises
        on the estimated Commencement Date hereof, Landlord shall not be liable
        for any damage caused thereby, nor shall this Lease be void or voidable,
        but Tenant shall not be liable for any rent until possession is
        delivered, at which time the term shall commence and the Expiration Date
        shall be extended so as to give effect to the full stated term. Tenant
        may terminate this Lease if possession is not delivered within 120 days
        of the estimated Commencement Date.

16.     LANDLORD'S INSURANCE: Landlord shall obtain and maintain throughout the
        term of this Lease the following policies of insurance:

        16.1  Casualty. Fire and extended coverage insurance on the Building
              (excluding non-Building standard leasehold improvements) and on
              all Building standard improvements; and

        16.2  General Liability. Comprehensive general and contractual liability
              insurance against claims for personal injury, death and property 
              damage occurring in or about the Building.

        Said insurance shall be maintained with an insurance company authorized
        to do business in Texas, in amounts desired by Landlord and at the
        expense of Landlord (but with the same to be included in the operating
        expenses of the Building as described in Paragraph 2.3) and payments for
        losses thereunder shall be made solely to Landlord. If the annual
        premiums to be paid by Landlord for casualty insurance shall exceed the
        standard rates because of Tenant's operations within or contents of the
        Premises or because the improvements to the Premises are above Building
        standard, Tenant shall promptly pay the excess amount of the premium
        upon request by Landlord (and if necessary, Landlord may allocate the
        insurance costs of the Building to give effect to this sentence).
        Alternatively, Landlord may meet its insurance coverage hereunder
        through self-insurance coverage provided that the coverage thereunder is
        substantially similar to the coverage which would otherwise have been
        provided by a third party insurance carrier in order to comply with this
        Paragraph 16. In the event Landlord elects to self-insure, Landlord
        shall have the right to assess and include within Operating Expenses the
        amount of the premium which would have been payable had Landlord
        purchased such insurance.

17.     TENANT'S INSURANCE: At all times during the term of this Lease, Tenant
        shall, at its sole expense, procure and maintain the following types of
        insurance coverage:

        17.1  General Liability: Commercial general liability insurance against
              any and all damages and liability, including attorneys' fees on
              account or arising out of injuries to or the death of any person

              Premises in amounts not less than $1,000,000.00 for injury or 
              death of one or more persons in a single accident and $500,000.00
              for damage to property;

        17.2  Personal Property: Insurance adequate in amount to cover damage to
              or replacement of, as necessary, the Premises including, without
              limitation, leasehold improvements, trade fixtures, furnishings,

        17.3  Employers Liability/Workers Compensation: Employer's liability
              insurance and worker's compensation insurance providing statutory
              state benefits for all persons employed by Tenant in connection
              with the Premises as required by applicable law; and

        17.4  Other Insurance: Such other insurance in such amounts as may be
              required by Landlord against other insurable hazards as at the
              time are commonly insured against in case of prudent owners of
              comparable office projects in the area (Galleria/West Loop Area)
              in which the Project is located.

        17.5  Form of Insurance/Companies: All such insurance shall be in a form
              satisfactory to Landlord and carried with companies reasonably
              acceptable to Landlord that are licensed or authorized to do
              business in the State of Texas, are in good standing with the
              Department of Insurance in the State of Texas is located and have
              a rating issued by an organization regularly engaged in rating
              insurance companies (including specifically A.M. Best & Company)
              of not less than one rating below the top rating. Tenant shall
              provide Landlord with a Certificate of Insurance showing Landlord
              and Landlord's managing agent as an additional insured. The
              Certificate shall provide for a 10 day written notice to Landlord
              in the event of cancellation or material change of coverage. Not
              later than 30 days prior to the expiration of any coverage,
              renewals of or replacements for such contracts of insurance shall
              be delivered to Landlord, together with proof of payment of the
              associated premiums. In the event Tenant shall fail to procure any
              contract of insurance required under the terms hereof or any
              renewal of or replacement for any contract of insurance that is
              expiring or has been canceled, Landlord may, but shall not be
              obligated to, procure such insurance on behalf of Tenant and the
              cost thereof shall be payable to Landlord as additional rent
              within 10 days following written demand therefor.

        17.6  Waiver of Recovery and Subrogation: Notwithstanding anything in
              this Lease or any insurance policy to be obtained under this Lease
              to the contrary, Landlord and Tenant hereby waive any and all
              rights of recover, claims, actions and causes of action against

              Premises, or any

              insurance policies required to be obtained pursuant to this Lease

              all insurance policies required to be obtained by the parties
              hereto were in fact obtained), regardless of cause or origin of
              such loss or damage, including, without limitation, SOLE, JOINT,

              however, the waiver set forth in this Paragraph 17.6 shall not
              apply to any deductibles on insurance policies carried by Landlord
              or to any coinsurance penalty which Landlord might sustain. Each
              party waives and covenants that no insurer shall hold (and hereby
              waives on behalf of each such insurer) any right of subrogation
              against such other party. The parties shall cause their respective
              insurers to waive any right of subrogation in accordance with this
              Paragraph 17.6.

18.     UTILITIES AND SERVICES: Landlord shall use all reasonable efforts to
        furnish (as part of Operating Expenses) heating, ventilation, air
        conditioning, janitorial service, elevator service, hot and cold water
        for reasonable and normal drinking and lavatory use, replacement light
        bulbs and/or fluorescent tubes and ballasts for standard overhead
        fixtures and sufficient electricity to operate (i) typewriters,
        calculating machines, photocopying machines and other machines of

        billed, such charges as may be separately metered or as Landlord's
        engineer shall reasonably compute for any electrical service usage in
        excess of that stated above. If Tenant's use of the Premises requires
        separate metering and/or air conditioning in excess of Building
        standard, the same shall be purchased and installed at Tenant's expense
        and Tenant shall pay all operating costs relating thereto. In addition
        to the above described services, Landlord shall provide equipment and
        personnel to limit access to the Building after normal business hours;
        provided, however, Landlord shall have no responsibility to prevent, and

<PAGE>   17


        Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day
        and Christmas Day. Landlord, from time to time during the term of this
        Lease, shall have the right to designate additional holidays, provided
        that such additional holidays are commonly recognized by other office
        buildings in the Galleria/Post Oak area of Houston, Texas. Utilities and
        services required at other times shall be subject to a charge of $35.00
        per hour or fraction thereof. Landlord shall not be liable for failure
        to furnish any of the utilities described in this Paragraph 18 and
        Tenant shall have no right to abatement of rental hereunder or to
        termination of this Lease with respect to any such interruption nor
        shall such failure constitute an eviction, nor shall Landlord be liable
        under any circumstances for loss of or injury to property, however
        occurring through or in connection with or incidental to the furnishing
        of any of the services enumerated above.

19.     CONDEMNATION: If 25% or more of the land area of the Project shall be
        taken or condemned for public use or acquired under threat of
        condemnation, Landlord may elect to terminate this Lease effective on
        the date of taking; otherwise this Lease will remain in full force and
        effect. If there is a taking of all of the Premises or a part thereof so
        that the remaining part of the Premises is not suited for Tenant's
        continued use, either party may elect to terminate this Lease effective
        on the date of taking. If there is a taking of a portion of the Premises
        and a part remains which is suitable for Tenant's use, this Lease shall,
        as to the part taken, terminate as of the date the condemnor acquires
        possession, and thereafter Tenant shall be required to pay such
        proportion of the rent for the remaining term as the value of the
        Premises remaining bears to the total value of the Premises at the date
        of condemnation. The election to terminate this Lease as provided herein
        must be exercised, if at all, within 60 days after the nature and extent
        of the taking is determined, otherwise, this Lease will remain in full
        force and effect. All sums which may be payable on account of any
        condemnation shall belong solely to the Landlord, and Tenant shall not
        be entitled to any part thereof, provided however, that Tenant shall be
        entitled to retain any amount awarded to it for its trade fixtures or
        moving expenses.

20.     TRADE FIXTURES: Any and all improvements made to the Premises during the
        term hereof shall unless Landlord requests that removal, belong to the
        Landlord without compensation, allowance or credit to Tenant, except
        movable trade fixtures of the Tenant which can be removed without
        defacing the Premises or the Project.

21.     DESTRUCTION OF PREMISES:

        21.1  Partial Destruction: In the event of a partial destruction of the
              Premises during the term hereof, from any cause covered by
              insurance, Landlord must repair the same to the extent such
              repairs can be made with the insurance proceeds made available to
              Landlord and within 60 days under then existing governmental laws
              and regulations. Such partial destruction shall not terminate this
              Lease and Tenant shall be entitled to a proportionate reduction of
              rent while such repairs are being made, based upon the extent to
              which the making of such repairs shall interfere with the business
              of Tenant


                                      -18-
<PAGE>   18


              on the Premises. If such repairs cannot be made within said 60 day
              period, Landlord, at his option, may make the repairs within a
              reasonable time. If Landlord elects to make said repairs, this
              Lease will continue in effect and the rent will be proportionately
              abated as stated above. If the repairs cannot be made within 60
              days with the available insurance proceeds and Landlord elects not
              to make said repairs, this Least may be terminated at the option
              of either party.

        21.2  Material/Total Destruction: If the Building in which the Premises
              are situated or the Project sustains damage of more than 1/3 of
              the replacement cost thereof, Landlord may elect to terminate this
              Lease whether the Premises are injured or not. A total destruction
              of the Building in which the Premises are situated or the Project
              shall terminate this Lease.

22.     HAZARDOUS SUBSTANCES:

        22.1  Definitions: For the purposes of this Agreement, the following
              terms have the following meanings:

              (a) "ENVIRONMENTAL LAW" means any law, statute, ordinance or
              regulation pertaining to health, industrial hygiene or the
              environment including, without limitation CERCLA (Comprehensive
              Environmental Response, Compensation and Liability Act of 1980),
              RCRA (Resources Conservation and Recovery Act of 1976) and SARA

              (b) "HAZARDOUS SUBSTANCE" means any substance, material or waste

              similarly designated, classified or regulated, under any

              and all permits, licenses and other governmental and regulatory
              approvals required for Tenant's use of the Premises. Tenant will
              not cause or permit any Hazardous Substance to be brought upon,
              kept or used in or about the Project by Tenant, its agents,
              employees, contractors, licensees, guests or invitees without the

              materials and wastes. Tenant will, in all respects, handle, treat,

              all Hazardous Substances placed on, under or about the Premises by
              Tenant or at Tenant's direction to be


                                         -19-

              removed and transported for use, storage or disposal in accordance
              and compliance with all applicable Environmental Laws. Tenant will
              not take any remedial action in response to the presence of any
              Hazardous Substances in or about the Premises or the Project, nor
              enter into any settlement agreement, consent decree or other
              compromise in respect to any claims relating to any Hazardous
              Substances in any way connected with the Promises without first

              Landlord ample opportunity to appear, intervene or otherwise
              appropriately assert and protect Landlord's interests with respect
              thereto.

        22.3  Indemnification: If the Premises or the Project become
              contaminated in any manner for which Tenant is liable or otherwise
              become affected by any release or discharge of a Hazardous
              Substance, Tenant shall immediately notify Landlord of the release
              or discharge of the Hazardous Substance, and Tenant shall
              indemnify, defend (by counsel reasonably acceptable to Landlord)
              and hold harmless Landlord and Landlord's agents, employees,
              officers, directors, partners and shareholders from and against
              any and all claims, damages, fines, judgments, penalties, costs,
              liabilities or losses (including, without limitation, a decrease
              in value of the Project or the Premises, damages caused by loss or
              restriction of rentable or usable space, or any damages caused by
              adverse impact on marketing of the space, and any and all sums
              paid for settlement of claims, attorneys' fees, consultant fees
              and expert fees) arising during or after the term of this Lease
              and arising as a result of such contamination, release or
              discharge. This indemnification includes, without limitation, any
              and all costs incurred because of any investigation of the site or
              any cleanup, removal or restoration mandated by federal, state or
              local agency or political subdivision.

 23.    EVENTS OF DEFAULT: If one or more of the following events ("Event of
        Default") occurs, such occurrence constitutes a breach of this Lease by
        Tenant:

        23.1  Abandonment/Vacation: Tenant abandons or vacates the Premises
              without giving Landlord ten (10) days prior written notice or

        23.3  Other Sum: Tenant fails to pay any other sum or charge payable by
              tenant hereunder as and when the same becomes due and payable, and
              such failure continues for more than 30 days after Landlord gives
              written notice thereof to Tenant; or

        23.4  Other Provisions: Tenant fails to perform or observe any other
              agreement, covenant, condition or provision of this Lease to be
              performed or observed by Tenant as and when performance or

     24.1    Remedies: Upon any Event of Default, Landlord may exercise any one
             or more of the following described remedies, in addition to all
             other rights and remedies provided at law or in equity:

             (a) Terminate this Lease by written notice to Tenant and forthwith
             repossess the Premises and be entitled to recover forthwith as
             damages a sum of money equal to the total of (i) the cost of
             recovering the Premises (including attorneys' fees and costs of
             suit), (ii) the cost of removing and storing any personal property,
             (iii) the unpaid rent earned at the time of termination, plus
             interest thereon at the rate described in Paragraph 5.2, (iv) the
             present value (discounted at the rate of eight percent (8%) per
             annum) of the balance of the rent for the remainder of the lease
             term less the present value (discounted at the same rate) of the
             fair market rental value of the Premises for said period, taking
             into account the period of time the Premises will remain vacant
             until a new tenant is obtained, and the cost to prepare the
             Premises for occupancy and the other costs (such as leasing
             commissions and attorneys' fees) to be incurred by Landlord in
             connection therewith, and (v) any other sum of money and damages
             owed by Tenant to Landlord under this Lease.

             (b) Elect to receive liquidated damages in an amount equal to the

             hereunder for the month during which this Lease is terminated times
             12, which amount shall be in lieu of the payment of damages
             Landlord may suffer by reason of such termination, but which shall
             not be in lieu of or reduce in any way any amount due from Tenant
             (including accrued rent) or damages incurred by Landlord due to
             breach by Tenant of any covenant or other obligation herein
             (whether or not liquidated) which accrued prior to the termination
             of this Lease. Nothing contained in this Lease shall limit or
             prejudice the right of Landlord to prove for and obtain in any
             proceedings to enforce Landlord's rights hereunder, including
             without limitation, any proceedings for bankruptcy or insolvency by
             reason of the termination of this Lease, proceedings equal to the
             maximum allowed by any statute or rule of law in effect at the time
             when, and governing the proceedings in which, the damages are to be
             proved, whether or not the amount be greater, equal to, or less
             than the amount of the loss or damages referred to above.

             (c) Terminate Tenant's right of possession (but not this Lease) and
             may repossess the Premises by forcible entry and detainer suit or
             otherwise, without thereby releasing Tenant from any liability
             hereunder and without demand or notice of any kind to Tenant and
             without terminating this Lease. Landlord shall use reasonable
             efforts under the circumstances to relet the Premises on such terms
             and conditions as Landlord in its sole discretion may determine
             (including a term different than the term of this Lease, rental
             concessions, alterations and repair of the Premises); provided,
             however,

             Landlord hereby reserves the right (i) to lease any other
             comparable space available in the Building or in any adjacent
             building owned by Landlord prior to offering the Premises for
             lease, and (ii) to refuse to lease the Premises to any potential
             tenant which does not meet Landlord's standards and criteria for
             leasing other comparable space in the Building. Landlord shall not
             be liable, nor shall Tenant's obligations hereunder be diminished
             because of, Landlord's failure or refusal to relet the Premises or
             collect rent due in respect of such reletting. For the purpose of
             such reletting Landlord shall have the right to decorate or to make
             any repairs, changes, alterations or additions in or to Premises as
             may be reasonably necessary or desirable. In the event that (i)
             Landlord shall fail or refuse to relet the Premises, or (ii) the
             Premises are relet and a sufficient sum shall not be realized from
             such reletting (after first deducting therefrom, for retention by
             Landlord, the unpaid rent due hereunder earned but unpaid at the
             time of reletting plus interest thereon at the rate specified in
             Paragraph 5.2, the cost of recovering possession (including
             attorneys' fees and costs of suit), all of the costs and expenses
             of such decorations, repairs, changes, alterations and additions,
             the expense of such reletting and the cost of collection of the
             rent accruing therefrom) to satisfy the rent, then Tenant shall
             pay to Landlord as damages a sum equal to the amount of such
             deficiency. Any such payments due Landlord shall be made upon
             demand therefor from time to time and Tenant agrees that Landlord
             may file suit to recover any sums falling due under the terms of
             this Paragraph 24.1(c) from time to time. No delivery to or
             recovery by Landlord of any portion due Landlord hereunder shall be
             any defense in any action to recover any amount not theretofore
             reduced to judgement in favor of Landlord, nor shall such reletting
             be construed as an election on the part of Landlord to terminate
             this Lease unless a written notice of such intention be given to
             Tenant by Landlord. Notwithstanding any such termination of
             Tenant's right of possession of the Premises, Landlord may at any
             time thereafter elect to terminate this Lease. In any proceedings
             to enforce this Lease under this Paragraph 24.1(c), Landlord
             shall be presumed to have used its reasonable efforts to relet the
             Premises, and Tenant shall bear the burden of proof to establish
             that such reasonable efforts were not used. 

             (d) Alter any and all locks and other security devices at the
             Premises, and if it does so Landlord shall not be required to
             provide a new key or other access right to Tenant unless Tenant has
             cured all Events of Default; provided, however, that in any such
             instance, during Landlord's normal business hours and at the
             convenience of Landlord, and upon the written request of Tenant
             accompanied by such written waivers and releases as Landlord may
             require, Landlord will escort Tenant or its authorized personnel to
             the Premises to retrieve any personal belongings or other property
             of Tenant not subject to the Landlord's lien or security interest
             described in Paragraph 25, The provisions of this Paragraph 24.1(d)
             are intended to override and control any conflicting provisions of
             the Texas Property Code.

                  In the event that Landlord shall have taken possession of the
             Premises pursuant to the authority herein granted, then Landlord
             shall have the right to keep in place and

                                   -23-

<PAGE>   23








             use all of the furniture, fixtures and equipment at the Premises,
             including that which is owned by or leased to Tenant at all times
             prior to any foreclosure thereon by Landlord or repossession
             thereof by any lessor thereof or third party having a lien thereon.
             Landlord shall also have the right to remove from the Premises
             (without the necessity of obtaining a distress warrant, writ of
             sequestration or other legal process and without being liable for
             prosecution or any claim for damages therefor) all or any portion
             of such furniture, fixtures, equipment and other property located
             thereon and place same in storage at any place within the county in
             which the Premises are located; and in such event, Tenant shall be
             liable to Landlord for costs incurred by Landlord in connection
             with such removal and storage and shall indemnify and hold Landlord
             harmless from all loss, damage, cost, expense and liability in
             connection with such removal and storage. Landlord shall also have
             the right to relinquish possession of all or any portion of such
             furniture, fixtures, equipment and other property to any person
             ("Claimant") claiming to be entitled to possession thereof who
             presents to Landlord a copy of any instrument represented to
             Landlord by Claimant to have been executed by Tenant (or any
             predecessor of Tenant) granting Claimant the right under various
             circumstances to take possession of such furniture, fixtures,
             equipment or other property, without the necessity on the part of
             Landlord to inquire into the authenticity of said instrument and
             without the necessity of Landlord's making any nature of
             investigation or inquiry as to the validity of the factual or legal
             basis upon which Claimant purports to act; and Tenant agrees to
             indemnify and hold harmless from all costs, expense, loss, damage
             and liability incident to Landlord's relinquishment of possession
             of all or any portion of such furniture, fixtures, equipment or
             other to Claimant.

     24.2    Non-Waiver. No action by the Landlord shall be deemed to imply or
             constitute a waiver by Landlord of any of Landlord's rights under
             this Lease unless such waiver is in writing and signed by Landlord
             and acknowledges that such action taken by Landlord is an express
             waiver of Landlord's rights. Furthermore, any such writing shall
             not be deemed to be a continuing waiver of Landlord's rights and
             shall be expressly limited to actions recited in any such waiver.
             Landlord shall have the right to declare any default under the
             Lease not waived in writing at any time and take such action as
             might be lawful or authorized. 

25.  SECURITY DEPOSIT: The Security Deposit set forth in Paragraph 1.7, if any, 
     shall secure the performance of the Tenant's obligations hereunder.
     Landlord may, but shall not be obligated to apply all or portions of the
     Security Deposit on account of Tenant's obligations thereunder. In the
     event that Landlord applies all or a portion of the Security Deposit to
     tenant's obligations hereunder, Tenant shall be obligated, within 10
     business days of receipt of notice from Landlord, to deposit cash with
     Landlord in an amount sufficient to restore the Security Deposit to the
     full amount stated in Paragraph 1.7 above. Failure to deposit such cash
     shall be a default under the terms of this Lease, Provided Tenant is not in
     default, any balance remaining upon termination shall be returned to
     Tenant. Tenant shall not have the right to

                                   -24-

<PAGE>   24









     apply the Security Deposit in payment of the last month's rent. No interest
     shall be paid by Landlord on the Security Deposit. In the event of a sale
     of the Project, Landlord shall have the right to transfer the Security
     Deposit to the purchaser, upon such transfer Landlord shall have no further
     liability with respect thereto, and Tenant agrees to look solely to such
     purchaser for the return of the Security Deposit. Landlord shall not be
     required to keep the Security Deposit in a segregated account, and the
     Security Deposit may be commingled with other funds of Landlord.
     Notwithstanding the foregoing, the Security Deposit shall be returned to
     the Tenant at the end of the 38th month so long as Tenant is not in default
     and no event of default has existed.

26.  LIEN FOR RENT: In addition to and independent of any lien in favor of
     Landlord arising by operation of law, Tenant hereby grants to Landlord a
     security interest to secure payment of all Base Rent and other sums of
     money becoming due hereunder from Tenant, and to secure payment of any
     damages or loss which Landlord may suffer by reason of the breach by Tenant
     of any covenant, agreement or condition contained herein, upon all goods,
     wares, equipment, fixtures, furnishings, inventory, improvements and other
     personal property that is not encumbered of Tenant presently or which
     hereafter may be situated in or on the Premises, and all proceeds
     therefrom, and such property shall not be removed therefrom without the
     consent of Landlord until any and all other sums of money then due to
     Landlord hereunder, first shall have been paid and discharged, and all
     covenants, agreements and conditions hereof have been fully complied with
     and performed by Tenant. At any time and from time to time, Tenant agrees
     to execute any UCC-1 Financing Statement (but not more than twice per
     annum) or such other documents or instruments as Landlord may request to
     perfect or confirm the security interest created by this Paragraph 26.
     Upon any failure by Tenant to do so, Landlord may execute same for and on
     behalf of Tenant as Tenant's attorney in fact. All exemption laws are
     hereby waived by Tenant to the extent permitted by law. This lien and
     security interest may be foreclosed with or without court proceedings, by
     public or private sale, with or without notice (to the extent permitted by
     law), and Landlord shall have the right to become purchaser upon being the
     highest bidder at such sale. Landlord, as secured party, shall be entitled
     to all the rights and remedies afforded a secured party under the Uniform
     Commercial Code, which rights and remedies shall be in addition to and
     cumulative of the Landlord's liens and rights provided by law or by the
     terms and provisions of this Lease.

27.  LIMITATION ON LANDLORDS PERSONAL LIABILITY: Tenant specifically agrees to
     look solely to Landlord's interest in the Project for the recovery of any
     judgment from Landlord, it being agreed that Landlord (and any officers,
     shareholders, directors, partners or employees of Landlord) shall never be
     personally liable for any such judgment,

28.  ATTORNEY'S FEES: In the event Tenant defaults in the performance of any of
     the terms, covenants, agreements or conditions contained in this Lease and
     Landlord places the enforcement of this Lease or the collection of any rent
     due or to become due hereunder or recovery of the possession of the
     Premises in the hands of an attorney, Tenant agrees to pay Landlord
     reasonable attorneys' fees and costs. If there is any legal action or
     proceeding

                                          -25-


<PAGE>   25








     between Landlord and Tenant to enforce any provision of this Lease or to
     protect or establish any right or remedy of either Landlord or Tenant
     hereunder, the unsuccessful party to such action or proceeding will pay to
     the prevailing party all costs and expenses, including reasonable
     attorneys' fees (including allocated costs of Landlord's in-house attorney)
     incurred by such prevailing party in such action or proceeding and in any
     appearance in connection therewith, and if such prevailing party recovers a
     judgment in any such action, proceeding or appeal, such costs, expenses and
     attorney's fees will be determined by the court handling the proceeding and
     will be included in and as a part of such judgment.

29.  SEVERABILITY: If any clause or provisions of this Lease is illegal, invalid
     or unenforceable under present or future laws effective during the term
     hereof, then it is the intention of the parties hereto that the remainder
     of this Lease shall not be affected thereby, and it is also the intention
     of both parties that in lieu of each clause or provision that is illegal,
     invalid or unenforceable, there shall be added as a part of this Lease, a
     clause or provision as similar in terms to such illegal, invalid or
     unenforceable clause or provision as may be possible and be legal, valid
     and enforceable.

30.  NOTICES: All notices or other communications required or permitted
     hereunder must be in writing, and be (i) personally delivered (including by
     means of professional messenger service), (ii) sent by overnight courier,

     received 2 days after the date of mailing.

31.  HOLDING OVER: Any holding over after the expiration or termination of this
     Lease shall create a tenancy at sufferance relationship and Tenant shall be
     required to pay a rental of 150% of the rent for the month of the Lease
     preceding the month in which the expiration or termination occurred, and
     otherwise in accordance with the terms hereof, as applicable. In the event
     Tenant shall be or become a holdover tenant, Tenant shall also indemnify
     Landlord against all claims for damages against Landlord as a result of
     Tenant's possession of the Premises, including, without limitation, claims
     for damages by any tenant to whom Landlord may have leased the Premises, or
     any portion thereof, for a term commencing after the expiration or

     the lien of any mortgage, deed of trust, ground lease and/or security

<PAGE>   26








     any future time be placed upon the Project, the Premises or Landlord's
     rights hereunder, and to any renewals, extensions, modifications or
     consolidations thereof. This clause shall be self-operative and no further
     instrument of subordination need be required by any holder of any such
     mortgage, deed of trust, ground lease and/or security agreement. In
     confirmation of such subordination, however, Tenant, at Landlord's request,
     shall execute promptly any appropriate certificate or instrument that
     Landlord may reasonably request. This Lease is further subject to and
     subordinate to all matters of record in Harris County, Texas.

35.  ESTOPPEL CERTIFICATE; FINANCIAL STATEMENTS:

35.1 Content: Tenant shall at any time, but not more than three (3) times per

     prospective purchaser or encumbrancer to the Premises. 

35.2 Failure to Deliver: At Landlord's option, Tenant's failure to deliver such
     statement within such time shall be a material breach of this Lease or 
     shall be conclusive upon Tenant:

     (a) that this Lease is in full force and effect, without modification
     except as may be represented by Landlord;

     (b) that there are no uncured defaults in Landlord's performance; and

     (c) that not more than one month's rent has been paid in advance or such
     failure may be considered by Lessor as a default by Tenant under this
     Lease.

     during the term of this Lease and after the end of the term of this Lease
     and if at any time Landlord desires to finance, refinance, or sell the

     legal counsel has also signed this Lease to confirm (i) that he has acted

     indirectly identified, suggested or selected by the Landlord in connection

     consideration as agreed to by Landlord has been predicated upon the
     inapplicability of the DTPA to this Transaction and that Landlord, in
     determining to proceed with the entering into of this Lease, has expressly
     relied on the inapplicability of the DTPA to this Transaction.

     AND INTENTIONALLY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR
     PROCEEDING THAT LANDLORD OR TENANT MAY HEREINAFTER INSTITUTE AGAINST EACH

     THE PREMISES.

     reviewed by an attorney on behalf of Tenant, or has had the opportunity to

     the drafting of this Lease.
