              and in all other parts of the Building and the appurtenances
              thereto, except for any defect which is not discoverable upon a
              reasonable inspection, but such acceptance shall not limit
              Landlord's obligations set forth elsewhere in this Lease.

       4.     USE. The Premises shall be used for office purposes, which
       includes, but is not limited to, conference and computer facilities, a
       non-commercial employee kitchen and related facilities, and other legally
       permitted business office uses consistent with the characteristics of a
       first-class office building in Dallas, Texas, (the "PERMITTED USE") and
       for no other purpose. Tenant agrees not to use or permit the use of the
       Premises for any purpose which is illegal, dangerous to life, limb or
       property or which, in Landlord's opinion, creates a nuisance or which
       would increase the cost of insurance coverage with respect to the
       Building. In the event there shall be any increase in the cost of
       insurance coverage with respect to the Building which results from
       Tenant's acts or conduct of business, then Tenant hereby agrees to pay
       the amount of such increase on demand. Tenant will conduct its business
       and control its agents, servants, employees, customers, licensees, and
       invitees in such a manner as not to interfere with, annoy or disturb
       other tenants or Landlord in the management of the Building. Tenant will
       maintain the Premises in a clean and healthful condition, and comply with
       all laws, ordinances, orders, rules and regulations of any governmental
       entity with reference to the use, condition or occupancy of the Premises.
       Tenant will comply with the rules and regulations of the Building adopted
       and altered by Landlord from time to time and will cause all of its
       agents, employees, invitees and visitors to do so. All changes to such
       rules and regulations will be sent by Landlord to Tenant in writing. A
       copy of the existing rules and regulations is attached hereto as Exhibit
       "H" and made a part hereof. Tenant agrees not to commit or allow any
       waste to be committed on any portion of the Premises, and at the
       termination of this Lease to deliver up the Premises to Landlord in as
       good condition as at the Commencement Date, ordinary wear and tear
       excepted. The terms of this Lease shall control over any conflict with
       rules and regulations. Rules and regulations cannot impose additional
       economic obligations on Tenant and shall be fairly applied and enforced
       by Landlord.

       5.     BASE RENTAL.

              (a)    Tenant covenants and agrees to pay during the Lease Term,
              to Landlord, without any setoff or deduction whatsoever, the Base
              Rental, and all such other sums of money as shall become due
              hereunder as additional rent, all of which are sometimes herein
              collectively called "rent." In the event of nonpayment of any such
              rent, Landlord shall be entitled to exercise all such rights and
              remedies as are herein provided in the case of the nonpayment of
              Base Rental. Except as otherwise provided herein, the annual Base
              Rental for each calendar year or portion thereof during the Lease
              Term, together with any estimated adjustment thereto pursuant to
              Exhibit "C" hereof then in effect, shall be due and payable in
              advance in twelve (12) equal installments on the first day of each
              calendar month during the initial term of this Lease and any
              extensions or renewals hereof, and Tenant hereby agrees to pay
              such Base Rental and any adjustments thereto to Landlord at
              address provided herein (or such other address as may be
              designated by Landlord in writing from time to time) monthly, in
              advance, and without demand. If the term of this Lease commences
              on a day other than the first day of a month or terminates on a
              day other than the last day of a month, then the installments of
              Base Rental and any adjustment thereto for such month or months
              shall be prorated, based on the number of days in such month. The
              Base Rental for the first partial month, if any, shall be payable
              at the beginning of said period. All such payments shall be by a
              good and sufficient check (subject to collection) drawn on a bank
              acceptable to Landlord. No payment by Tenant or receipt or
              acceptance by Landlord of a lesser amount than the correct
              installment of rent due under this Lease shall be deemed to be
              other than a payment on account of the earliest rent due
              hereunder, nor shall any endorsement or statement on any check or
              any letter accompanying any check or payment be deemed an accord
              and


                                       6

<PAGE>
                                                                   EXHIBIT 10.7



              satisfaction, and Landlord may accept such check or payment
              without prejudice to Landlord's right to recover the balance or
              pursue any other remedy provided by this Lease or applicable law.
              The acceptance by Landlord of an installment of rent on a date
              after the due date of such payment shall not be construed to be a
              waiver of Landlord's right to declare a default for any other late
              payment. If Tenant fails to timely pay any two (2) installments of
              rent in any consecutive twelve month period, Landlord may require
              Tenant to pay rent (as estimated by Landlord, if necessary)
              quarterly in advance, and, in such event, all future payments
              shall be made on or before the due date in cash or by cashier's
              check or money order, and the delivery of Tenant's collectible
              personal or corporate check shall no longer constitute payment
              thereof. Any acceptance of Tenant's collectible personal or
              corporate check thereafter by Landlord shall not be construed as a
              waiver of the requirement that such payments be made in cash or by
              cashier's check or money order. All amounts received by Landlord
              from Tenant hereunder shall be applied first to the earliest
              accrued and unpaid rent then outstanding.

              (b)    All installments of rent not paid when due and payable
              shall bear interest until paid at a per annum rate equal to the
              lesser of (i) the Prime Rate plus five percent (5%) or (ii) the
              Maximum Rate.

              (c)    The Base Rental payable hereunder shall be adjusted upward
              from time to time in accordance with the provisions of EXHIBIT "C"
              attached hereto and incorporated herein for all purposes.

       6.     SECURITY DEPOSIT. The Security Deposit shall be held by Landlord
       without liability for interest and as security for the performance by
       Tenant of Tenant's covenants and obligations under this Lease including
       but not limited to those set forth in Paragraph 10 hereof, it being
       expressly understood that the Security Deposit shall not be considered an
       advance payment of rent or a measure of Tenant's liability for damages in
       case of default by Tenant. Landlord may commingle the Security Deposit
       with Landlord's other funds. Landlord may, from time to time, without
       prejudice to any other remedy, use the Security Deposit to the extent
       necessary to make good any arrearages of rent or to satisfy any other
       covenant or obligation of Tenant hereunder. Following any such
       application of the Security Deposit, Tenant shall pay to Landlord on
       demand the amount so applied in order to restore the Security Deposit to
       its original amount. If Tenant is not in default at the termination of
       this Lease, the balance of the Security Deposit remaining after any such
       application shall be returned by Landlord to Tenant. If Landlord
       transfers its interest in the Premises during the term of this Lease,
       Landlord shall assign the Security Deposit to the transferee and
       thereafter shall have no further liability for the return of such
       Security Deposit. Tenant agrees to look solely to such transferee or
       assignee or successor thereof for the return of the Security Deposit.
       Landlord and its successors and assigns shall not be bound by any actual
       or attempted assignment or encumbrance of the Security Deposit by Tenant.

       7.     SERVICES TO BE FURNISHED BY LANDLORD. Landlord shall provide to
       Tenant, at no additional or separate charge to Tenant, for the services
       listed in this Paragraph 7, the level and quality of services typically
       provided by landlords of buildings of the same quality as the Building
       within a radius of two miles of the Building and Tenant shall be entitled
       to install and operate photocopiers, telephone and telecopy equipment,
       word processing equipment, computers and other equipment customarily used
       in first class office space in such area without additional charge.
       Charges for additional services shall not exceed Landlord's reasonable
       charges. The services Landlord is obligated to provide shall include:

              (a)    Hot and cold water at those points of supply provided for
              general use of tenants in the Building, central heat and air
              conditioning in season, at such temperatures and in such amounts
              as are considered by Landlord to be standard for comparable
              buildings or as required by governmental authority; provided,
              however, heating and air conditioning service at times other than
              for Normal Business Hours for the Building shall be furnished only
              upon the written request of Tenant delivered to Landlord prior to
              3:00 p.m. at least one Business Day in advance of the date for
              which such usage is requested. Tenant shall bear the entire cost
              of additional service as such costs are determined by Landlord
              from time to time. Tenant shall have the right to install separate
              HVAC equipment, which will be separately metered and paid by
              Tenant. The current after hours rate for HVAC is $49.00 per


                                       7

                                                                   EXHIBIT 10.7



              hour, with a two hour minimum, during the Lease Term. This rate
              is subject to change due to changes in electricity rates charged
              to Landlord.

              (b)    Routine maintenance and electric lighting service for all
              Common Areas and Service Areas of the Building in the manner and
              to the extent deemed by Landlord to be standard.

              (c)    Janitor service on Business Days; provided, however, if
              Tenant's floor covering or other improvements require special
              treatment, Tenant shall pay the additional cleaning cost
              attributable thereto as additional rent upon presentation of a
              statement therefor by Landlord.

              (d)    Subject to the provisions of Paragraph 11 hereof,
              facilities to provide all electrical current required by Tenant in
              its use and occupancy of the Premises.

              (e)    All fluorescent bulb replacement in the Premises necessary
              to maintain the lighting provided by Landlord as set forth in the
              Work Letter Agreement attached hereto as Exhibit "D" as a part of
              the Building Standard Materials and fluorescent and incandescent
              bulb replacement in the Common Areas and Service Areas.

              (f)    Passenger elevators for ingress and egress to and from the
              floor of the Premises during Normal Business Hours and with at
              least one passenger elevator available at all other times.

              (g)    Access control to the Building during other than Normal
              Business Hours shall be provided in such form as Landlord deems
              appropriate consistent with buildings of the same quality as the
              Building within a radius of two miles of the Building. Coded
              access cards will be provided to Tenant's authorized employees for
              after hours access to the Building, and a fee will be charged by
              Landlord based on its costs for such cards. Tenant also shall have
              the right, at its sole cost and expense, to install and operate
              such additional access control systems as it shall determine for
              the purpose of limiting access to or within the Premises, provided
              that Tenant gets Landlord's written approval of such systems
              before installation and provided that Landlord shall be provided
              access to such systems to enter Tenant's space at any time. Tenant
              shall cooperate fully in Landlord's efforts to maintain access
              control to the Building and shall follow all regulations
              promulgated by Landlord with respect thereto.

              (h)    Access to Landlord's delivery docks, if any, for use only
              during the construction of the Tenant Improvements (as hereinafter
              defined), subject to Landlord's rules and regulations regarding
              use of the delivery docks and subject to Landlord's prior written
              approval of Tenant's proposed use of the delivery docks.

       Except as otherwise expressly provided herein, the failure by Landlord to
       any extent to furnish, or the interruption or termination of these
       defined services in whole or in part, resulting from adherence to laws,
       regulations and administrative orders, FORCE MAJEURE or any other causes
       beyond the reasonable control of Landlord shall not render Landlord
       liable in any respect nor be construed as an eviction of Tenant, nor work
       an abatement of rent, nor relieve Tenant from the obligation to fulfill
       any covenant or agreement hereof. Should any of the equipment or
       machinery used in the provision of such services for any cause cease to
       function properly, Landlord shall use reasonable diligence to repair such
       equipment or machinery but, except as otherwise expressly provided
       herein, Tenant shall have no claim for offset or abatement of rent or
       damages on account of an interruption in service thereby or resulting
       therefrom. Except as expressly provided herein, Landlord shall not be
       required to make any repairs to or maintain the Premises. However, if
       services are interrupted or abated for any reason, or if Landlord
       interferes with Tenant's operations as a result of the exercise by
       Landlord of its right to enter into the Premises, or perform services or
       work with respect to any other portion of the Building, and as a result
       of such interruption, Tenant cannot use the Premises in substantially the
       same manner as prior to such interruption for five (5) consecutive
       business days, Tenant shall have the right to abate rent on a pro rata
       basis based on the amount of the Premises which are substantially
       unusable until such interference is remedied. Landlord shall maintain the
       Building, all structural components thereof, all base building
       improvements, all mechanical, electrical, and plumbing facilities,
       outside of the Premises, not including any HVAC equipment installed by
       Tenant, the roof and roof membrane, all utilities, all parking areas, and
       all common areas in a condition comparable to that of other buildings
       comparable to the Building within a two mile radius of the Building.

       8.     IMPROVEMENTS TO BE MADE BY LANDLORD. Except as otherwise provided
       in the Work Letter Agreement attached hereto as EXHIBIT "D", all
       installations and improvements now or hereafter placed on or in the
       Premises shall be subject to the provisions of Paragraph 10 hereof and
       shall be for Tenant's account and at Tenant's cost (and Tenant shall pay
       ad valorem taxes and increased insurance thereon or attributable
       thereto), which cost shall be payable by Tenant to Landlord upon demand
       as additional rent.

       9.     GRAPHICS. Landlord shall provide and install, at Tenant's cost,
       all letters or numerals on the exterior of the Premises; all such letters
       and numerals shall be in the standard graphics for the Building and no
       others shall be used or permitted on the Premises without Landlord's
       prior written consent. Tenant acknowledges that the standard Building
       graphics are acceptable to Tenant. Additionally Landlord, at Tenant's
       sole cost, may install a monument sign bearing only Tenant's name. Before
       any such installation, Landlord shall have the right to approve the
       location, size, design and materials used in the sign. The sign shall be
       subject to approval by all city officials and agencies governing the sign
       and shall comply with all applicable laws and ordinances. At the end of
       the Lease Term (and the Renewal Term, if applicable), at Landlord's
       option, Tenant at Tenant's sole cost, shall remove the sign and shall
       restore the Building and the Property to a condition at least as good as
       that condition which existed immediately prior to the installation of the
       sign.

       10.    REPAIRS AND ALTERATIONS BY TENANT. Tenant covenants and agrees
       with Landlord, at Tenant's own cost and expense, to keep the Premises in
       good condition and repair and to repair or replace any damage done to the
       Building, or any part thereof, caused by Tenant or Tenant's agents,
       servants, employees, customers, licensees, or invitees. Tenant further
       covenants and agrees that such repairs shall restore the Building to as
       good a condition as it was in prior to such damage and that such repairs
       shall be effected in compliance with all applicable laws. If Tenant fails
       to make such repairs or replacements promptly, Landlord may, at its
       option, make such repairs or replacements, and Tenant shall pay the cost
       thereof to the Landlord on demand as additional rent. Tenant agrees with
       Landlord not to make or allow to be made any alterations to the Premises,
       install any vending machines on the Premises, or place signs on the
       Premises which are visible from outside the Premises, without first
       obtaining the written consent of Landlord in each such instance, which
       consent may be refused or given on such conditions as Landlord may elect.
       Any and all alterations, additions and improvements to the Premises, all
       attached furniture, equipment and fixtures, and any unattached and
       movable equipment, furniture, trade fixtures or other personality which
       was acquired with funds provided by or on behalf of Landlord shall become
       the property of Landlord upon termination of this Lease. In addition, all
       other personal property which shall remain in the Premises for more than
       five (5) days following either the termination of this Lease or the entry
       of the Premises by Landlord following Tenant's default hereunder shall,
       at Landlord's option, become the property of Landlord. Landlord shall,
       nonetheless, require Tenant to remove such fixtures, furniture, trade
       fixtures, equipment, improvements, alterations, additions and personal
       property installed on or located in the Premises as are designated by
       Landlord at the time plans are approved by Landlord (the "REQUIRED
       REMOVABLES") at Tenant's sole cost including without limitation, any
       cabling or other computer, satellite or telecommunications equipment or
       hardware, whether or not such equipment cabling or hardware is located in
       the Premises and repair any damage to the Premises or the Building caused
       by such removal. In the event that Landlord so elects, and Tenant fails
       to remove the Required Removables, Landlord may remove the Required
       Removables at Tenant's cost, and Tenant shall pay Landlord on demand all
       costs incurred in removing, storing and/or disposing of the Required
       Removables.

       11.    USE OF ELECTRICAL SERVICES BY TENANT. Tenant's use of electrical
       services furnished by Landlord shall not exceed, either in voltage, rated
       capacity, or overall load that which Landlord deems to be standard for
       the Building. In the event Tenant shall request that it be allowed to
       consume electrical services in excess of that deemed by Landlord to be
       standard for the Building, Landlord may refuse to consent to such usage
       or

                                       9

<PAGE>
                                                                   EXHIBIT 10.7


       may consent upon such conditions as Landlord elects (including the
       requirement that submeters be installed at Tenant's expense).


       12.    ENTRY BY LANDLORD. Tenant agrees to permit Landlord or its agents
       or representatives to enter into and upon any part of the Premises at all
       reasonable hours (and in emergencies at all times, by any means Landlord
       may deem proper, and without liability therefor) to inspect the same, or
       to show the Premises to prospective purchasers, mortgagees, tenants (only
       during the last nine months of the Lease Term) or insurers, or to clean
       or make repairs, alterations or additions thereto, and Tenant shall not
       be entitled to any abatement or reduction of rent by reason thereof.

       13.    ASSIGNMENT AND SUBLETTING.

              (a)    Tenant shall not assign, sublease, transfer or encumber
              this Lease or any interest therein or grant any license,
              concession or other right of occupancy of the Premises or any
              portion thereof or otherwise permit the use of the Premises or any
              portion thereof by any party other than Tenant (any of which
              events is hereinafter called an "ASSIGNMENT") without the prior
              written consent of Landlord. Any such attempted assignment in
              violation of the terms and covenants of this Paragraph shall, at
              Landlord's option, exercisable in Landlord's sole and absolute
              discretion, be void. Consent by Landlord to one or more
              assignments shall not operate as a waiver of Landlord's rights as
              to any subsequent assignments. In addition, Tenant shall not,
              without Landlord's consent, publicly offer to assign the Lease nor
              advertise the Lease for assignment in any media, including but not
              limited to newspapers, periodicals, radio, television, circulars
              or brochures. In the event Tenant or any agent, representative or
              broker acting on behalf of Tenant or with Tenant's knowledge
              violates the provisions of the foregoing sentence, in addition to
              all of the remedies which Landlord may have at law, in equity, or
              pursuant to the terms of this Lease, Landlord shall be entitled to
              seek injunctive relief preventing such action and Tenant shall be
              responsible for all costs incurred by Landlord in connection with
              seeking such injunctive relief.

              (b)    If Tenant requests Landlord's consent to an assignment,
              Tenant shall submit to Landlord, in writing, the name of the
              proposed assignee and the nature and character of the business of
              the proposed assignee, the term, use, rental rate and all other
              material terms and conditions of the proposed assignment,
              including, without limitation, evidence satisfactory to Landlord
              that the proposed assignee is financially responsible. Landlord
              shall either (i) consent to or refuse to consent to such
              assignment in writing (but no such consent to an assignment shall
              relieve Tenant or any guarantor of Tenant's obligations under this
              Lease of any liability hereunder), or (ii) negotiate directly with
              the proposed assignee and (in the event Landlord is able to reach
              agreement with such proposed assignee) upon execution of a lease
              with such assignee, terminate this Lease (in part or in whole, as
              appropriate) upon ninety (90) days' notice. If Landlord should
              fail to notify Tenant in writing of its decision within a thirty
              (30) day period after the later of the date Landlord is notified
              in writing of the proposed assignment or the date Landlord has
              received all required information concerning the proposed assignee
              and the proposed assignment, Landlord shall be deemed to have
              refused to consent to such assignment, and to have elected to keep
              this Lease in full force and effect. In the event Landlord
              consents to any such assignment, the assignment shall be on a form
              approved by Landlord, and Tenant shall bear all costs and expenses
              incurred by Landlord in connection with the review and approval of
              such documentation. Landlord will have no right to consent or to
              terminate this Lease as a result of any assignment or sublease to
              any affiliate of Tenant or to any entity that acquires all or
              substantially all of the assets of Tenant provided that the
              financial condition of said affiliate is at least equal to that of
              Tenant prior to the transfer and provided Tenant gives Landlord
              written notice of such action at least thirty (30) days before the
              action is taken. Changes in ownership of Tenant shall not be an
              assignment and sales of stock in Tenant shall not be considered an
              assignment provided that the financial condition of the Tenant
              after such sales or changes of ownership is at least as good as
              its financial condition prior to such sales or change of
              ownership. An "AFFILIATE" shall be defined as an entity that owns
              at least fifty-one percent (51%) of the equity and

              voting control of Tenant or an entity of which Tenant owns at
              least fifty-one percent (51%) of the equity and voting control.

              (c)    All cash or other proceeds of any assignment of Tenant's
              interest in this Lease and/or the Premises, whether consented to
              by Landlord or not, shall be paid to Landlord notwithstanding the
              fact that such proceeds exceed the rentals called for hereunder,
              unless Landlord agrees to the contrary in writing, and Tenant
              hereby assigns all rights it might have or ever acquire in any
              such proceeds to Landlord. In addition to the rent hereunder,
              Tenant hereby covenants and agrees to pay to Landlord all rent and
              other consideration which it receives which is in excess of the
              rent payable hereunder within ten (10) days following receipt
              thereof by Tenant. This covenant and assignment shall benefit
              Landlord and its successors in ownership of the Building and shall
              bind Tenant and Tenant's heirs, executors, administrators,
              personal representatives, successors and assigns. In addition to
              any other rights and remedies which Landlord may have hereunder,
              at law or in equity, in the event Tenant has failed to pay any
              rent due hereunder on or before five (5) days following the date
              on which it is due, Landlord shall have the right to contact any
              assignee and require that from that time forward all payments made
              pursuant to the assignment shall be made directly to the Landlord.
              Any assignee of Tenant's interest in this Lease (all such
              assignees being hereinafter referred to as "Successors"), by
              occupying the Premises and/or assuming Tenant's obligations
              hereunder, shall be deemed to have assumed liability to Landlord
              for all amounts paid to persons other than Landlord by such
              Successors in consideration of any such assignment in violation of
              the provisions hereof Tenant shall pay to Landlord the excess
              consideration received only from a non-affiliated sublease or
              assignment after Tenant has recouped brokerage commissions and the
              costs of Tenant Improvements incurred by Tenant in assigning or
              subleasing so that the excess consideration being paid is profit
              to Tenant net of the two listed costs. In the case of an
              affiliated assignment or sublease, no excess consideration will be
              paid to Landlord.

              (d)    If Tenant is a corporation and if at any time during the
              Lease Term the person or persons who own the voting shares at the
              time of the execution of this Lease cease for any reason,
              including but not limited to merger, consolidation or other
              reorganization involving another corporation, to own a majority of
              such shares or if Tenant is a partnership and if at any time
              during the Lease Term the general partner or partners who own the
              general partnership interests in the partnership at the time of
              the execution of this Lease, cease for any reason to own a
              majority of such interests (except as the result of transfers by
              gift, bequest or inheritance to or for the benefit of members of
              the immediate family of such original shareholder(s) or
              partner(s)), such an event shall be deemed to be an assignment.
              The preceding sentence shall not apply whenever Tenant is a
              corporation the outstanding stock of which is listed on a
              recognized security exchange, or if at least eighty percent (80%)
              of its voting stock is owned by another corporation, the voting
              stock of which is so listed , or as provided in Paragraph 13(b).

       14.    MECHANIC'S LIENS. Tenant will not permit any mechanic's liens or
       other liens to be placed upon the Premises, the Building, or the Property
       and nothing in this Lease shall be deemed or construed in any way as
       constituting the consent or request of Landlord, express or implied, by
       inference or otherwise, to any person for the performance of any labor or
       the furnishing of any materials to the Premises, the Building, or the
       Property or any part thereof, nor as giving Tenant any right, power, or
       authority to contract for or permit the rendering of any services or the
       furnishing of any materials that would give rise to any mechanic's or
       other liens against the Premises, the Building, or the Property. In the
       event any such lien is attached to the Premises, the Building, or the
       Property, then, in addition to any other right or remedy of Landlord,
       Landlord may, but shall not be obligated to, discharge the same. Any
       amount paid by Landlord for any of the aforesaid purposes including, but
       not limited to, attorneys fees, shall be paid by Tenant to Landlord
       promptly on demand as additional rent. In the event Landlord does consent
       to the performance of any labor or the furnishing of any materials to the
       Premises, the Building, or the Property by any party, which consent must
       be in writing, Tenant shall be responsible for insuring that all such
       persons procure and maintain insurance coverage against such risks, in
       such amounts and with such companies as Landlord may require, including,
       but not limited to, Builder's Risk and Worker's Compensation insurance.

       15.    PROPERTY INSURANCE.

              (a)    Landlord shall maintain fire and extended coverage
              insurance on the Building and the Premises in an amount not less
              than the full replacement cost of the Building, including parking
              areas with a reasonable deductible to be determined by Landlord.
              The cost of such insurance shall be included as a part of the
              Basic Costs, and payments for losses thereunder shall be made
              solely to Landlord or the mortgagees of Landlord as their
              interests shall appear.

              (b)    Tenant shall maintain at its expense, in an amount equal to
              full replacement cost, fire and extended coverage insurance on all
              of its personal property, including removable trade fixtures and
              leasehold and tenant improvements, located in the Premises and in
              such additional amounts as are required to meet Tenant's
              obligations pursuant to Paragraph 19 hereof. Tenant shall furnish
              evidence satisfactory to Landlord of the maintenance and timely
              renewal of such insurance, and Tenant shall obtain and deliver to
              Landlord a written obligation on the part of each insurer to
              notify Landlord at least thirty (30) days prior to the
              modification, cancellation or expiration of such insurance
              policies. In the event Tenant shall not have delivered to Landlord
              a policy or certificate evidencing such insurance at least thirty
              (30) days prior to the expiration date of each expiring policy,
              Landlord may obtain such insurance as Landlord may reasonably
              require to protect Landlord's interest (which obtaining of
              insurance shall not be deemed to be a waiver of Tenant's default
              hereunder). The cost to Landlord of obtaining such policies, plus
              an administrative fee in the amount of fifteen percent (15%) of
              the cost of such policies shall be paid by Tenant to Landlord as
              additional rent upon demand.

              (c)    Landlord and Tenant each hereby waives on behalf of itself
              and its insurers (none of which shall ever be assigned any such
              claim or be entitled thereto due to subrogation or otherwise) any
              and all rights of recovery, claim, action, or cause of action,
              against the other, its agents, officers or employees, for any loss
              or damage that may occur to the Premises, or any improvements
              thereto or the Building of which the Premises are a part, or any
              improvements thereto, or any personal property of such party
              therein, by reason of fire, the elements, or any other cause(s)
              which are, or could be, insured against under the terms of the
              standard tire and extended coverage insurance policies referred to
              in this Paragraph 15, regardless of whether such insurance is
              actually maintained and regardless of the cause or origin of the
              damage involved, including sole, joint or concurrent, negligence
              of the other party hereto, its agents, officers, or employees.

       16.    LIABILITY AND WORKER'S COMPENSATION INSURANCE.

              (a)    Tenant and Landlord shall, each at its own expense,
              maintain during the term of this Lease a policy or policies of
              comprehensive general liability insurance (including endorsement
              or separate policy for owned or non-owned automobile liability)
              with respect to the respective activities of each in the Building
              and on the Property, with the premiums thereon fully paid on or
              before the due date, issued by and binding upon an insurance
              company or companies reasonably approved by Landlord. Such
              insurance shall afford minimum protection of not less than
              $1,000,000.00 per occurrence per person coverage for bodily
              injury, property damage, personal injury, or combination thereof.
              The term "personal injury" herein used means false arrest,
              detention or imprisonment, malicious prosecution, wrongful entry,
              libel and slander. If only a combined single limit coverage is
              available, it shall be for at least $1,000,000.00 per occurrence
              with an umbrella policy of at least $5,000,000.00 combined single
              limit per occurrence. Tenant's insurance policy shall name
              Landlord as an additional insured and shall include coverage for
              the contractual liability of Tenant to indemnify Landlord pursuant
              to Paragraph 17 of this Lease.

              (b)    Tenant shall obtain and maintain in force worker's
              compensation and employer's liability insurance to cover Tenant's
              liability to its employees.

                                                                   EXHIBIT 10.7



              (c)    Landlord and Tenant each hereby waives subrogation on its
              behalf and on behalf of its insurer, to the extent subrogation on
              a paid claim can be legally waived prior to loss by contract
              between the parties, in respect of any payment made by such
              insurer under any liability or worker's compensation policy.
              Neither Landlord nor Tenant shall be liable to the other or any
              insurance company (by way of subrogation or otherwise) insuring
              the other party for any loss or damage to any building, structure
              or other tangible property, or bodily injury or personal injury,
              or any resulting loss of income, or losses from workers'
              compensation laws and benefits, even though such loss or damage
              might have been occasioned by the negligence of such party, its
              agents or employees, if any such loss or damage is covered by
              insurance benefiting the party suffering such loss or damage or
              was required to be covered by insurance pursuant to this Lease.

              (d)    Each party shall use its good faith efforts to cause its
              general liability, automobile liability and worker's compensation
              policies to be endorsed by the issuing insurer waiving rights of
              subrogation of such insurer against the other party hereto. The
              failure of any insurer to issue such endorsement shall not be
              deemed to limit or alter the force and effect of Paragraph 16(c)
              of this Lease.

       17.    INDEMNITY. Neither Landlord or Building Manager nor any of their
       respective officers, directors, employees, or agents shall be liable to
       Tenant, or to Tenant's agents, servants, employees, customers, licensees,
       or invitees for any injury to person or damage to property caused by any
       act, omission, or neglect of Tenant, its agents, servants, employees,
       customers, invitees, licensees or any other person entering the Building
       or upon the Property under the invitation of Tenant or arising out of the
       use of the Property, Building or Premises by Tenant and the conduct of
       its business or out of a default by Tenant in the performance of its
       obligations hereunder. TENANT HEREBY INDEMNIFIES AND HOLDS LANDLORD AND
       BUILDING MANAGER AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AND
       AGENTS ("INDEMNITEES"), HARMLESS FROM ALL LIABILITY AND CLAIMS FOR ANY
       PROPERTY DAMAGE, OR BODILY INJURY OR DEATH OF, OR PERSONAL INJURY TO, A
       PERSON IN OR ON THE PREMISES, OR AT ANY OTHER PLACE, INCLUDING THE
       PROPERTY OR THE BUILDING, CAUSED, IN WHOLE OR IN PART, BY THE NEGLIGENCE
       OR WILLFUL MISCONDUCT OF TENANT, ITS EMPLOYEES, AGENTS, SERVANTS,
       CUSTOMERS, INVITEES OR LICENSEES AND THIS INDEMNITY SHALL BE ENFORCEABLE
       TO THE FULL EXTENT WHETHER OR NOT SUCH LIABILITY AND CLAIMS ARE THE
       RESULT OF THE SOLE, JOINT OR CONCURRENT ACTS, NEGLIGENT OR INTENTIONAL,
       OR OTHERWISE, OF TENANT, OR ITS EMPLOYEES, AGENTS, SERVANTS, CUSTOMERS,
       INVITEES OR LICENSEES. SUCH INDEMNITY FOR THE BENEFIT OF INDEMNITEES
       SHALL BE ENFORCEABLE EVEN IF INDEMNITEES, OR ANY ONE OR MORE OF THEM HAVE
       OR HAS CAUSED OR PARTICIPATED IN CAUSING SUCH LIABILITY AND CLAIMS BY
       THEIR JOINT OR CONCURRENT ACTS, NEGLIGENT OR INTENTIONAL, OR OTHERWISE.
       Landlord will indemnify and hold Tenant harmless from and against any
       claims, losses, demands, liabilities, damages, and expenses (including
       legal fees) caused by the willful misconduct or gross negligence of
       Landlord, its agents, servants, and employees.

       18.    HAZARDOUS MATERIALS. Tenant represents and warrants that Tenant
       and all of its agents, servants, employees, customers, invitees,
       licensees or any other persons on or adjacent to the Building for the
       purpose of engaging in business or providing services for the Tenant,
       shall not (either with or without negligence) cause or permit the escape,
       disposal or release of any biologically or chemically active or other
       hazardous substances, or material. Tenant shall not allow the storage or
       use of such substances or materials in any manner not sanctioned by law
       or by the highest standards prevailing in the industry for the storage
       and use of such substances or materials, nor allow to be brought into the
       Building or onto the Property any such materials or substances except to
       use in the ordinary course of Tenant's business, and then only after
       written notice is given to Landlord of the identify of such substances or
       materials. Without limitation, hazardous substances and materials shall
       include those described in the Comprehensive Environmental Response,
       Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section
       9601 et seq., any applicable state or local laws and the regulations
       adopted under these acts.  If any lender or governmental agency shall
       ever require testing to ascertain whether or not there has been any
       release of hazardous materials, then the reasonable costs thereof shall
       be reimbursed by Tenant to Landlord upon demand as additional charges if
       such requirement applies to the Premises. In addition, Tenant shall
       execute affidavits, representations and the like from time to time at
       Landlord's request concerning Tenant's best knowledge and belief
       regarding the presence of hazardous substances or materials on the
       Premises. In the event that


                                      13

<PAGE>
                                                                   EXHIBIT 10.7


       Tenant receives any notice form any governmental authority with regard
       to biologically or chemically active or other hazardous material, or
       substances on, from or affecting the Building, Tenant shall promptly
       notify Landlord. TENANT HEREBY INDEMNIFIES AND HOLDS INDEMNITEES
       HARMLESS FROM ALL LIABILITY, ACTIONS, PENALTIES, LIENS AND/OR CLAIMS
       ARISING FROM, CAUSED BY, IN WHOLE OR IN PART, BY THE ESCAPE, DISPOSAL,
       RELEASE, IMPROPER USE, STORAGE, INSTALLATION OR OTHER ACTION INVOLVING
       ANY BIOLOGICALLY OR CHEMICALLY ACTIVE OR HAZARDOUS MATERIALS OR
       SUBSTANCES BY THE TENANT, ITS EMPLOYEES, AGENTS, SERVANTS, CUSTOMERS,
       INVITEES OR LICENSEES. THIS INDEMNITY SHALL BE ENFORCEABLE TO THE FULL
       EXTENT WHETHER OR NOT SUCH LIABILITY AND CLAIMS ARE THE RESULT OF THE
       SALE, JOINT OR CONCURRENT SETS, NEGLIGENT OR INTENTIONAL, OR
       OTHERWISE, OF TENANT, OR ITS EMPLOYEES, AGENTS, SERVANTS, CUSTOMERS,
       INVITEES OR LICENSEES. Landlord shall be responsible, at its cost, and
       not as an Operating Expense, to keep the Building free of all
       Hazardous Materials, the presence of which was caused by Landlord's
       willful misconduct or gross negligence, and indemnifies Tenant from
       all loss, liability, damage and expense arisen from the presence of
       Hazardous Materials, the presence of which was caused by Landlord's
       willful misconduct or gross negligence. Hazardous Materials shall be
       deemed not to include materials customarily used by office building
       tenants, contractors and vendors in quantities that do not violate
       Environmental Laws.

       19.    EVIDENCE OF INSURANCE. On or before five (5) days following the
       date of this Lease, Tenant will cause its insurer(s) to issue and deliver
       to Landlord certificate(s) of insurance in the form attached hereto as
       EXHIBIT "F" evidencing the existence and coverage of insurance required
       herein.

       20.    CASUALTY DAMAGE. If the Premises or any part thereof shall be
       damaged by fire or other casualty, Tenant shall give prompt written
       notice thereof to Landlord. In case the Building shall be so damaged that
       substantial alteration or reconstruction of the Building (meaning more
       than fifty percent [50%] of the Building) shall, be required (whether or
       not the Premises shall have been damaged by such casualty) or in the
       event of any material uninsured loss to the Building (meaning more than
       fifty percent [50%] of the Building), Landlord may, at its option,
       terminate this Lease by notifying Tenant in writing of such termination
       within ninety (90) days after the date of such casualty. If Landlord
       chooses to complete the repair work, but Landlord cannot reasonably be
       expected to substantially complete its repair work within 270 days from
       the date on which Landlord determines it will repair, then Tenant may, at
       its option, terminate this Lease by notifying Landlord in writing of such
       termination within ninety (90) days after the date of such casualty. If
       Landlord does not thus elect to terminate this Lease, Landlord shall
       commence and proceed with reasonable diligence to restore the Building,
       and the improvements located within the Premises, if any, for which
       Landlord had financial responsibility pursuant to the Work Letter
       Agreement attached hereto as EXHIBIT "D" (except that Landlord shall not
       be responsible for delays not within the control of Landlord) to
       substantially the same condition in which it was immediately prior to the
       happening of the casualty. Notwithstanding the foregoing, Landlord's
       obligation to restore the Building, and the improvements located within
       the Premises, if any, for which Landlord had financial responsibility
       pursuant to the Work Letter Agreement, shall not require Landlord to
       expend for such repair and restoration work more than the insurance
       proceeds actually received by the Landlord as a result of the casualty
       and Landlord's obligation to restore shall be further limited so that
       Landlord shall not be required to expend for the repair and restoration
       of the improvements located within the Premises, if any, for which
       Landlord had financial responsibility pursuant to the Work Letter
       Agreement, more than the dollar amount of the Allowance, if any,
       described in the Work Letter Agreement. When the repairs described in the
       preceding two sentences have been completed by Landlord, Tenant shall
       complete the restoration of all improvements, including furniture,
       fixtures and equipment, which are necessary to permit Tenant's
       reoccupancy of the Premises. Except as set forth above, all cost and
       expense of reconstructing the Premises shall be home by Tenant, and
       Tenant shall present Landlord with evidence satisfactory to Landlord of
       Tenant's ability to pay such costs prior to Landlord's commencement of
       repair and restoration of the Premises. Tenant shall not be entitled to
       receive any credit or payment with respect to any portion of the
       Reconstruction Allowance not actually spent upon restoration of the
       Premises. Landlord shall not be liable for any inconvenience or annoyance
       to Tenant or injury to the business of Tenant resulting in any way from
       such damage or the repair thereof, except that, subject to the provisions
       of the next sentence, Landlord shall allow Tenant a fair diminution of
       rent during the time and to the extent the Premises are unfit for
       occupancy. If the Premises or any other portion of the Building is
       damaged by fire or other

       casualty resulting from the fault or negligence of Tenant or any of
       Tenant's agents, employees, or invitees, the rent hereunder shall not
       be diminished during the repair of such damage and Tenant shall be
       liable to Landlord for the cost of the repair and restoration of the
       Building caused thereby to the extent such cost and expense is not
       covered by insurance proceeds.

       21.    DAMAGES FROM CERTAIN CAUSES. Landlord shall not be liable to
       Tenant for any injury to person or damage to property sustained by Tenant
       or any person claiming through Tenant resulting from any accident or
       occurrence in the Premises or any other portion of the Building caused by
       the Premises or any other portion of the Building becoming out of repair
       or by defect in or failure of equipment, pipes, or wiring, or by broken
       glass, or by the backing up of drains, or by gas, water, steam,
       electricity, or oil leaking, escaping or flowing into the Premises
       (except where due to Landlord's willful failure to make repairs required
       to be made pursuant to other provisions of this Lease, after the
       expiration of a reasonable time after written notice to Landlord of the
       need for such repairs), nor shall Landlord be liable to Tenant for any
       loss or damage that may be occasioned by or through the acts or omissions
       of other tenants of the Building or of any other persons whomsoever,
       including, but not limited to riot, strike, insurrection, war, court
       order, requisition, order of any governmental body or authority, acts of
       God, fire or theft except to the extent caused by Landlord's gross
       negligence or willful misconduct and except that Landlord shall
       nevertheless be obligated to perform its maintenance, repair and other
       obligations under this Lease.

       22.    CONDEMNATION. If the whole or any substantial part of the Premises
       or if the Building or any portion thereof which would leave the remainder
       of the Building unsuitable for use as an office building comparable to
       its use on the Commencement Date, shall be taken or condemned for any
       public or quasi-public use under governmental law, ordinance or
       regulation, or by right of eminent domain, or by private purchase in lieu
       thereof, then Landlord may, at its option, terminate this Lease and the
       rent shall be abated during the unexpired portion of this Lease,
       effective when the physical taking of said Premises or said portion of
       the Building shall occur. In the event this Lease is not terminated, the
       rent for any portion of the Premises so taken or condemned shall be
       abated during the unexpired term of this Lease effective when the
       physical taking of said portion of the Premises shall occur. All
       compensation awarded for any such taking or condemnation, or sale
       proceeds in lieu thereof, shall be the property of Landlord, and Tenant
       shall have no claim thereto, the same being hereby expressly waived by
       Tenant, except for any portions of such award or proceeds which are
       specifically allocated by the condemning or purchasing party for the
       taking of or damage to trade fixtures of Tenant, which Tenant
       specifically reserves to itself provided Tenant's award does not diminish
       the Landlord's award. If any portion of the Premises, access thereto,
       parking, or roof top space shall be taken so as to render a substantial
       portion of the Premises unoccupiable for Tenant's business, for five
       consecutive business days, Tenant, at Tenant's option, may choose to
       abate the Basic Rent on a pro rata basis based on the percent of the
       Premises which are unusable after the stated five-day period.

              (a)    DEFAULT BY TENANT. The occurrence of any one or more of the

                            now or hereafter established to govern the operation
                            of the Building;

                     (iii)  An assignment or subletting by Tenant without the

                            declare Tenant a bankrupt or to delay, reduce or

                            or taken by any governmental authority for the
                            dissolution or liquidation of Tenant and, within
                            thirty (30) days thereafter, Tenant fails to secure

                            Premises without giving Landlord written  notice of

                            over and above Base Rental and Basic Costs provided
                            in this Lease to be paid by Tenant to Landlord. For
                            the purposes of such reletting Landlord is
                            authorized to decorate or to make any repairs,
                            changes, alterations or additions in or to the
                            Premises that may be necessary. Landlord may file
                            suit to recover sums falling due under the terms of
                            this Section 23(b)(iii) from time to time, and 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 judgment in favor of Landlord. No reletting shall
                            be construed as an election on the part of Landlord
                            to terminate this Lease unless in favor of Landlord.
                            No reletting shall be construed as an election on
                            the part of Landlord to terminate this Lease unless
                            a written notice of such intention is given to
                            Tenant by

                                                                   EXHIBIT 10.7


                            Landlord. Notwithstanding any such reletting
                            without termination, Landlord may at any time
                            thereafter elect to terminate this Lease for such
                            previous default and/or exercise its other rights
                            under this Lease.

                     (iii)  Enter upon the Premises and do whatever Tenant is
                            obligated to do under this Lease; and Tenant agrees
                            to reimburse Landlord on demand for any expenses
                            which Landlord may incur in effecting compliance
                            with Tenant's obligations under this Lease plus
                            fifteen percent ( 15%) of such cost to cover
                            overhead plus interest at the past due rate provided
                            in this Lease, and Tenant further agrees that
                            Landlord shall not be liable for any damages
                            resulting to Tenant from such action. No action
                            taken by Landlord under this Section 23(b)(iv) shall
                            relieve Tenant from any of its obligations under
                            this Lease or from any consequences or liabilities
                            arising from the failure to perform such
                            obligations.

                     (iv)   Without waiving such default, apply all or any part
                            of the Security Deposit and/or any unapplied Prepaid
                            Rental to cure the default or to any damages
                            suffered as a result of the default to the extent of
                            the amount of damages suffered. Tenant shall
                            reimburse Landlord for the amount of such depletion
                            of the Security Deposit and/or any Prepaid Rental on
                            demand.

                     (v)    Change all door locks and other security devices of
                            Tenant at the Premises and/or Building, and Landlord
                            shall not be required to provide the new key to the
                            Tenant except during Tenant's regular business
                            hours, and only upon the condition that Tenant has
                            cured any and all defaults hereunder and in the case
                            where Tenant owes Base Rental and/or Basic Costs, or
                            any other sums under this Lease to the Landlord,
                            reimbursed Landlord for all Base Rental and Basic
                            Costs and other sums due Landlord hereunder.
                            Landlord, on terms and conditions satisfactory to
                            Landlord in its sole discretion, may upon request
                            from Tenant's employees, enter the Premises for the
                            purpose of retrieving therefrom personal property of
                            such employees, provided, Landlord shall have no
                            obligation to do so.

                     (vi)   Exercise any and all other remedies available to
                            Landlord in this Lease, at law or in equity.

       24.    TENANT REMEDIES. Except to the extent specifically provided
       herein, Tenant shall not have the right to an abatement of rent or to
       terminate this Lease as a result of Landlord's default as to any covenant
       or agreement contained in this Lease or as a result of the breach of any
       promise or inducement in connection herewith, whether in this Lease or
       elsewhere and Tenant hereby waives such remedies of abatement of rent and
       termination. Tenant hereby agrees that Tenant's remedies for default
       hereunder or in any way arising in connection with this Lease including
       any breach of any promise or inducement or warranty, express or implied,
       shall be limited to:

              (a)    A suit for direct and proximate damages provided that
              Tenant has given the notices as hereinafter required.
              Notwithstanding anything to the contrary contained in this Lease,
              the liability of Landlord to Tenant for any default by Landlord
              under the terms of this Lease shall be limited to the interest of
              Landlord in the Building and the Property and Tenant agrees to
              look solely to Landlord's interest in, the Building and the
              Property for the recovery of any judgment against the Landlord, it
              being intended that Landlord shall not be personally liable for
              any judgment or deficiency. Tenant hereby covenants that, prior to
              the filing of any suit for direct and proximate damages, it shall
              give Landlord and all mortgagees whom Tenant has been notified
              hold mortgages or deed of trust liens on the Property, Building or
              Premises ("LANDLORD'S MORTGAGEES") notice and reasonable time to
              cure any alleged default by Landlord.

                                                                   EXHIBIT 10.7


              (b)    In the event Landlord fails to commence the cure of a
              material default of any material covenant or agreement contained
              in this Lease within sixty (60) days following receipt of notice
              specifying such alleged default from Tenant by both Landlord and
              Landlord's mortgagees, equitable abatement of the Base Rental and
              other rent due hereunder to the extent reasonably necessary to
              adjust for any inconvenience occasioned by Landlord's failure to
              theretofore commence the cure of such default.

       The rights of Tenant pursuant to this Section shall be subject to (and,
       if applicable, Tenant shall have the benefit of) the express provisions
       of this Lease, if any, providing for remedies different from, and in
       exclusion of, the remedies above-described. For example, the foregoing
       notice and grace periods shall not apply to Tenant's right to abate rent
       or terminate this Lease for utility interruptions. Landlord's interest in
       the Building and the Property shall include all insurance proceeds and
       condemnation awards, subject to the claims of other tenants.

       25.     NO WAIVER. Failure of Landlord to declare any default immediately
       upon its occurrence, or delay in taking any action in connection with an
       event of default, shall not constitute a waiver of such default, nor
       shall it constitute an estoppel against Landlord, but Landlord shall have
       the right to declare the default at any time and take such action as is
       lawful or authorized under this Lease. Failure by Landlord to enforce its
       rights with respect to any one default shall not constitute a waiver of
       its rights with respect to any subsequent default. Receipt by Landlord of
       Tenant's keys to the Premises shall not constitute an acceptance of
       surrender of the Premises.

       26.    EVENT OF BANKRUPTCY. In addition to, and in no way limiting the
       other remedies set forth herein Landlord and Tenant agree that if Tenant
       ever becomes the subject of a voluntary or involuntary bankruptcy,
       reorganization, composition, or other similar type proceeding under the
       federal bankruptcy laws, as now enacted or hereinafter amended, then:

              (a)    "ADEQUATE PROTECTION" of Landlord's interest in the
              Premises pursuant to the provisions of Section 361 and 363 (or
              their successor sections) of the Bankruptcy Code, 11 U.S.C.
              Paragraph 101, ET SEQ. (such Bankruptcy Code as amended from time
              to time being herein referred to as the "Bankruptcy Code"), prior
              to assumption and/or assignment of the Lease by Tenant shall
              include, but not be limited to all (or any part) of the following:

                     (i)    the continued payment by Tenant of the Base Rental
                            and all other rent due and owing hereunder and the
                            performance of all other covenants and obligations
                            hereunder by Tenant;

                     (ii)   the hiring of security guards to protect the
                            Premises if Tenant abandons and/or ceases
                            operations; such obligation of Tenant only to be
                            effective so long as Tenant remains in possession
                            and control of the Premises to the exclusion of
                            Landlord;

                     (iii)  the furnishing of an additional/new security deposit
                            by Tenant in the amount of three (3) times the
                            then-current monthly Base Rental and other rent
                            payable hereunder.

              (b)    "ADEQUATE ASSURANCE OF FUTURE PERFORMANCE" by Tenant and/or
              any assignee of Tenant pursuant to Bankruptcy Code Section 365
              will include (but not be limited to) payment of an additional/new
              Security Deposit in the amount of three (3) times the then-current
              monthly Base Rental and monthly escrow for Basic Costs payable
              hereunder.

              (c)    Any person or entity to which this Lease is assigned
              pursuant to the provisions of the Bankruptcy Code, shall be deemed
              without further act or deed to have assumed all of the obligations
              of Tenant arising under this Lease on and after the effective date
              of such assignment. Any such assignee shall, upon demand by
              Landlord, execute and deliver to Landlord an instrument confirming
              such assumption of liability.

              (d)    Notwithstanding anything in this Lease to the contrary, all
              amounts payable by Tenant to or on behalf of the Landlord under
              this Lease, whether or not expressly denominated as "rent", shall
              constitute "rent" for the purposes of Section 502(b)(6) of the
              Bankruptcy Code.

              (e)    If this Lease is assigned to any person or entity pursuant
              to the provisions of the Bankruptcy Code, any and all monies or
              other considerations payable or otherwise to be delivered to
              Landlord (including Base Rentals and other rent hereunder), shall
              be and remain the exclusive property of Landlord and shall not
              constitute property of Tenant or of the bankruptcy estate of
              Tenant. Any and all monies or other considerations constituting
              Landlord's property under the preceding sentence not paid or
              delivered to Landlord shall be held in trust by Tenant or Tenant's
              bankruptcy estate for the benefit of Landlord and shall be
              promptly paid to or turned over to Landlord.

              (f)    If Tenant assumes this Lease and proposes to assign the
              same pursuant to the provisions of the Bankruptcy Code to any
              person or entity who shall have made a bona fide offer to accept
              an assignment of this Lease on terms acceptable to the Tenant,
              then notice of such proposed offer/assignment, setting forth (i)
              the name and address of such person or entity; (ii) all of the
              terms and conditions of such offer, and (iii) the adequate
              assurance to be provided Landlord to assure such person's or
              entity's future performance under the Lease, shall be given to
              Landlord by Tenant no later than twenty (20) days after receipt by
              Tenant, but in any event no later than ten (10) days prior to the
              date that Tenant shall make application to a court of competent
              jurisdiction for authority and approval to enter into such
              assumption and assignment, and Landlord shall thereupon have the
              prior right and option, to be exercised by notice to Tenant given
              at any time prior to the effective date of such proposed
              assignment, to accept an assignment of this Lease upon the same
              terms and conditions and for the same consideration, if any, as
              the bona fide offer made by such persons or entity, less any
              brokerage commission which may be payable out of the consideration
              to be paid by such person for the assignment of this Lease.

              (g)    To the extent permitted by law, Landlord and Tenant agree
              that this Lease is a contract under which applicable law excuses
              Landlord from accepting performance from (or rendering performance
              to) any person or entity other than Tenant within the meaning of
              Sections 365(c) and 365(e)(2) of the Bankruptcy Code.

       27.    PEACEFUL ENJOYMENT. Tenant shall, and may peacefully have, hold,
       and enjoy the Premises, subject to the other terms hereof, provided that
       Tenant pays the rent and other sums herein recited to be paid by Tenant
       and performs all of Tenant's covenants and agreements herein contained.
       This covenant and any and all other covenants of Landlord shall be
       binding upon Landlord and its successors only with respect to breaches
       occurring during its or their respective periods of ownership of the
       Landlord's interest hereunder.

       28.    SUBSTITUTION. Landlord shall be entitled to cause Tenant to
       relocate from suite number 250 of the Premises to a comparable space with
       comparable improvements (the "RELOCATION SPACE") within the Building at
       any time upon prior written notice to Tenant. The reasonable costs
       actually incurred in connection with the physical relocation of the
       Tenant to the Relocation Space shall be at the expense of Landlord or the
       third party tenant replacing Tenant in suite 250 of the Premises and all
       other costs, if any, involved with such relocation shall be borne by
       Tenant. Such a relocation shall not terminate or otherwise affect or
       modify this Lease except that from and after the date of such relocation,
       "Premises" shall refer to the rest of the Premises not affected by this
       Paragraph 28 and the Relocation Space into which Tenant has been moved,
       rather than the original Premises as herein defined and the Base Rental
       shall be adjusted so that immediately following such relocation the Base
       Rental for the Relocation Space on a per square foot of Rentable Area
       basis shall be the same as the Base Rental immediately prior to such
       relocation for suite 250 of the Premises on a per square foot of Rentable
       Area basis.

       29.    HOLDING OVER. In the event of holding over by Tenant after
       expiration or other termination of this Lease or in the event Tenant
       continues to occupy the Premises after the termination of Tenant's right
       of


                                       20

                                                                   EXHIBIT 10.7


       possession pursuant to Paragraph 22(b) hereof, Tenant shall,
       throughout the entire holdover period, pay rent equal to 1.5 times the
       sum of the Base Rental plus the additional rent which would have been
       applicable had the term of this Lease continued through the period of
       such holding over by Tenant. No holding over by Tenant or payments of
       money by Tenant to Landlord after the expiration of the term of this
       Lease shall be construed to extend the term of this Lease or prevent
       Landlord from recovery of immediate possession of the Premises by summary
       proceedings or otherwise unless Landlord has sent written notice to
       Tenant that Landlord has elected to extend the term of the Lease. Tenant
       shall be liable to Landlord for all damage, including any consequential
       damage, which Landlord may suffer by reason of any holding over by Tenant
       and Tenant shall indemnify Landlord against any and all claims made by
       any other tenant or prospective tenant against Landlord for delay by
       Landlord in delivering possession of the Premises to such other tenant or
       prospective tenant. Nothing in this Paragraph or elsewhere in this Lease
       shall be construed as Landlord granting Tenant permission to holdover,
       which permission is denied unless Landlord agrees otherwise in writing
       prior to the end of the Lease Term.

       30.    SUBORDINATION TO MORTGAGE. This Lease and all rights and interests
       of Tenant hereunder are subject and subordinate to any mortgage, deed of
       trust or other lien presently existing or hereafter arising upon the
       Premises, or upon the Building and/or the Property, and to any renewals,
       modifications, refinancings and extensions thereof, but Tenant agrees
       that any such mortgagee shall have the right at any time to subordinate
       such mortgage, deed of trust or other lien to this Lease on such terms
       and subject to such conditions as such mortgagee may deem appropriate in
       its discretion; provided, however, that this Lease shall not be
       subordinate to any mortgage, ground lease, or master lease unless Tenant
       receives a non-disturbance agreement in a form agreeable to Landlord and
       to its tender and Tenant. Landlord will use reasonable efforts to obtain
       a non-disturbance agreement from all existing mortgage holders. This
       clause shall be self-operative and no further instrument of subordination
       shall be required. However, Landlord is hereby irrevocably vested with
       full power and authority to subordinate this Lease to any first mortgage,
       first deed of trust or other lien now existing or hereafter placed upon
       the Premises, or the Building and/or the Property and Tenant agrees upon
       demand to execute such further instruments subordinating this Lease or
       attorning to the holder of any such liens as Landlord may request. Tenant
       further agrees upon request by the holder of any such mortgage, deed of
       trust or other lien, before or after the institution of any proceedings
       for the foreclosure of any such mortgage, deed of trust or other lien (or
       deed in lieu of foreclosure) to attorn to such purchaser upon any such
       foreclosure (or deed in lieu thereof) and to recognize such purchaser as
       Landlord under this Lease. The agreement of Tenant to attorn upon request
       in the immediately preceding sentence shall survive any foreclosure sale
       or deed in lieu of foreclosure. Notwithstanding the foregoing, Tenant
       shall have no obligation to attorn unless Tenant has previously received
       a non-disturbance agreement satisfactory to Landlord and its lender. In
       the event that Tenant should fail to execute any subordination or other
       agreement required by this Paragraph promptly as requested, Tenant hereby
       irrevocably constitutes Landlord as its attorney-in-fact to execute such
       instrument in Tenant's name, place and stead, it being agreed that such
       power is one coupled with an interest in Landlord and is accordingly
       irrevocable. Tenant agrees that it will from time to time upon request by
       Landlord execute and deliver to such persons as Landlord shall request a
       statement in recordable form certifying that this Lease is unmodified and
       in full force and effect (or if there have been modifications, that the
       same is in full force and effect as so modified), stating the dates to
       which rent and other charges payable under this Lease have been paid,
       stating that Landlord is not in default hereunder (or if Tenant alleges a
       default stating the nature of such alleged default) and further stating
       such other matters as Landlord shall reasonably require.

       31.    ATTORNEY'S FEES. In the event either party defaults in the
       performance of any of the terms of this Lease and the other party employs
       an attorney in connection therewith, the defaulting party agrees to pay
       the prevailing party's reasonable attorneys' fees.

       otherwise expressly provided herein, be in writing, and may, unless
       otherwise in this Lease expressly provided, be given or be served by

       obligations.

       39.    COMMISSIONS. Landlord and Tenant hereby indemnify and hold each
       other harmless against an), loss, claim, expense or liability with

                     approximately 13,053 rentable square feet)

                                                                   EXHIBIT 10.7

                           PAYMENT OF EXCESS BASIC COSTS

       The Base Rental payable hereunder shall be adjusted upward from time to
time in accordance with the following provisions:

       1.     Tenant's Base Rental is based, in part, upon an Expense Base
       (herein so called) equal to the actual per square foot operating expenses
       for the Building for calendar year 1998. Tenant shall, during the Lease
       Term, pay as an adjustment to Base Rental hereunder an amount (per each
       square foot of Rentable Area within the Premises) equal to the excess
       ('Excess"), if any, from time to time of actual Basic Costs per square
       foot per year for the Rentable Area in the Building over the Expense
       Base. Prior to January I of each calendar year during Tenant's occupancy
       or as soon thereafter as practical, Landlord shall make a good faith
       estimate of the Excess for each upcoming calendar year and, upon prior
       written notice to Tenant, may require the monthly payment of Base Rental
       to be adjusted in accordance with such estimate.  Landlord shall have the
       right from time to time during any such calendar year to revise the
       estimate of the Excess for such year and provide Tenant with a revised
       statement therefor, and thereafter the amount Tenant shall pay each month
       shall be based upon such revised estimate. Any amounts paid based on any
       estimate shall be subject to adjustment pursuant to Paragraph 2 below
       when actual Basic Costs are available for such calendar year.

       2.     As soon as is practical following the era of each calendar year
       during Tenant's occupancy Landlord shall famish to Tenant a statement of
       Landlord's actual Basic Costs for the previous calendar year.  If for any
       calendar year additional Base Rental collected for the prior year, as a
       result of Landlord's estimate of Basic Costs, is in excess of the
       additional Base Rental actually due during such prior year, then Landlord
       shall refund to Tenant any overpayment (or at Landlord's option, apply
       such amount against rentals due or to become due hereunder). Likewise,
       Tenant shall pay to Landlord, on demand, any underpayment with respect to
       the prior year whether or not the Lease has terminated prior to receipt
       by Tenant of a statement for such underpayment.

       3.     Tenant or Tenant's independent accountant, at its expense, shall
       have the right no more frequently than once per calendar year, following
       thirty (30) days prior written notice to Landlord, to audit Landlord's
       books and records relating to Basic Costs at Landlord's office during
       Normal Business Hours. Tenant shall have the right to audit the then
       current and the immediately preceding accounting year if not previously
       audited.  If the audit reveals that Landlord's statement of Basic Costs
       was more than five percent (5%) in error, subject to Landlord's right to
       contest, Landlord will pay the costs of the audit up to an amount equal
       to the amount of Landlord's accounting error to Tenant's detriment.

       4.     "BASIC COSTS" shall mean all direct and indirect costs and
              expenses incurred in each calendar year in connection with
              operating, maintaining, repairing, managing and owning the
              Building and the Property, including, without limitation, the
              following:

              (a)  All labor costs for Landlord's employees (only at the level
              of Building manager and below as reasonably allocated on the time
              actually spent on the Building as opposed to other projects)
              performing services required or utilized in connection with the
              operation, repair and maintenance of and control of access to the
              Building and the Property, including but not limited to amounts
              incurred for wages, salaries and other compensation for services,
              payroll, social security, unemployment and other similar taxes,
              workmen's compensation insurance, disability benefits, pensions,
              hospitalization, and retirement plans and group insurance.

              (b)  All management fees (not to exceed market management fees),
              the cost of maintaining a management office at the Building, and
              all fees for legal and accounting services relating to the
              Building and the Property.

              (c)  All rental and/or purchase costs of materials, supplies, hand
              tools and equipment used in the operation, repair, replacement and
              maintenance and the control of access to the Building and the
              Property.

                                    EXHIBIT "D"
                               WORK LETTER AGREEMENT

       This Work Letter Agreement supplements and is hereby incorporated in that
certain lease (hereinafter referred to as the "Lease") dated and executed
concurrently herewith by and between Brookdale Investors, L.P. (hereinafter
referred to as "Landlord") and ObjectSpace, Inc., a Texas Corporation
(hereinafter referred to as "Tenant") with the terms defined in the Lease to
have the same definition where used herein.

       1.  The Premises are leased to Tenant in their "AS IS" condition and this
       Work Letter Agreement is intended to set forth the obligations of
       Landlord and Tenant with respect to the preparation of the Premises for
       Tenant's occupancy. All improvements described in this Work Letter
       Agreement to be constructed in and upon the Premises are hereinafter
       referred to as the "Tenant Improvements." It is agreed that construction
       of the Tenant Improvements will be completed in accordance with the
       procedures set forth in this Work Letter Agreement.

       2.  Tenant shall devote such time in consultation with Landlord or
       Landlord's agent as may be required to provide all necessary information
       to Landlord or Landlord's agent as Landlord deems necessary in order to
       enable Landlord to complete, and obtain Tenant's written approval of, the
       final layout, drawings, and plans for the Premises. All of Tenant's plans
       and specifications shall be subject to Landlord's consent, the granting
       or denial of which shall be in Landlord's sole discretion.

       3.  Space planning and construction drawings, and when deemed necessary
       by Landlord, engineering drawings, shall be prepared by Landlord's
       architect. Unless otherwise provided in EXHIBIT "D-2", Tenant shall pay
       for space planning services, for Landlord's standard construction and
       engineering drawings covering Landlord's Building Standard materials as
       defined in EXHIBIT "D-1", and for any nonstandard construction and
       engineering drawings, or any additional costs for drawings occasioned by
       special installation other than Building Standard. Tenant may pay for
       such services out of the Allowance, if any, provided in EXHIBIT "D-2".
       Tenant shall furthermore be responsible for the design, function and
       maintenance of all special improvements, whether installed by Landlord at
       Tenant's request or installed by Tenant with Landlord's prior written
       approval. Tenant shall use the Building Standard materials unless other
       materials are expressly approved in writing by Landlord.

       4.  Prior to commencing any construction of Tenant Improvements, Landlord
       shall submit to Tenant a written estimate setting forth the anticipated
       cost of the Tenant Improvements (excluding any costs which may be
       specified herein or in EXHIBIT "D-2", as being  borne by Landlord),
       including but not limited to labor and materials, contractor's fees
       (Landlord's construction management fees), permit fees, and space
       planning, construction, and engineering drawing costs which are the
       responsibility of Tenant.  Within five (5) Business Days Tenant shall
       either notify Landlord in writing of its approval of the cost estimate,
       or specify its objections thereto and desired changes to the proposed
       Tenant Improvements. In the event Tenant notifies Landlord of such
       objections and desired changes, Tenant shall work with Landlord to reach
       acceptable plans and cost estimate; provided, however, if Tenant fails to
       give written approval of a cost estimate within ten (10) Business Days
       following delivery to Tenant of the original cost estimate.

       5.  In the event Landlord's estimate and/or the actual cost of
       construction shall exceed the Allowance, (as defined in EXHIBIT "D-2"
       attached hereto), if any (such amounts exceeding the Allowance being
       herein referred to as the "Excess Costs"), Tenant shall pay to Landlord
       such Excess Costs as follows:

              (a)    Tenant shall deliver to Landlord, with its approval of the
              Landlord's estimate, and in any event prior to commencement of
              construction, an amount equal to fifty percent (50%) of the Excess
              Costs as then estimated by Landlord.

              (b)    After substantial completion of the Tenant Improvements,
              Tenant shall pay to Landlord on demand an amount which when added
              to the initial payment described in subparagraph (a) above equals
              ninety percent (90%) of the Excess Costs as then estimated by
              Landlord.

                                                                   EXHIBIT 10.7


              (c)    As soon as the final accounting can be prepared and
              submitted to Tenant, Tenant shall pay on demand to Landlord the
              entire balance of the Excess Costs based upon the actual cost of
              construction.

       The statements of costs submitted to Landlord by Landlord's contractors
       shall be conclusive for purposes of determining the actual cost of the
       items described therein.  The amounts payable hereunder constitute other
       rent payable pursuant to the Lease, and the failure to timely pay same
       constitutes an event of default under the Lease.

       6.     If Tenant shall request any change, addition or alteration in the
       working drawings, after approval by Landlord and Tenant, Landlord shall
       have such working drawings prepared, and Tenant shall promptly reimburse
       Landlord for the cost thereof.  Promptly upon completion of the
       revisions, Landlord shall notify Tenant in writing of the cost which will
       be chargeable to Tenant by reason of such change, addition or deletion.
       Tenant shall, within three (3) Business Days, notify Landlord in writing
       whether it desires to proceed with such change, addition or deletion.  In
       the absence of such written authorization, Landlord shall have the option
       to continue work on the Premises disregarding the requested change,
       addition or alteration, or Landlord may elect to discontinue work on the
       Premises.  In the event such revisions result in a higher estimate of the
       cost of construction, Tenant shall pay to Landlord an amount sufficient
       to provide Landlord with the above described fifty percent (50%) (or if
       applicable ninety percent (90%)) payment toward Excess Costs.

       7.     Following approval of the plans and the payment by Tenant of the
       required portion of the Excess Costs, if any, Landlord shall cause the
       Tenant Improvements to be constructed in accordance with the approved
       plans. Unless otherwise specifically provided in the approved plans, all
       material used in the construction of the Tenant's Improvements shall be
       of such quality as determined by the Landlord's architect. Landlord shall
       notify Tenant of substantial completion of the Tenant Improvements.

       8.     Any other language in this Exhibit D notwithstanding, the Tenant
       Improvements shall be constructed by one of the general contractors
       previously approved by Landlord.  A minimum of three bids to construct
       the Tenant Improvements will be received. Landlord shall select the
       general contractor to perform the work and will enter directly into a
       contract with that contractor for the Tenant Improvements.

       9.     Tenant shall have the option to utilize any items currently in
       place in the Premises, including but not limited to doors, lights and
       glass, at no additional cost to Tenant.  The Allowance shall not apply to
       these items.

                                   RENEWAL OPTION

       Provided that no event of default has ever occurred more than one time in
any consecutive twelve-month period under any term or provision contained in
this Lease and no condition exists which with the passage of time or the giving
of notice or both would constitute an event of default pursuant to this Lease
and provided that Tenant has continuously occupied the Premises for the
Permitted Use during the Lease Term, Tenant (but not any assignee or subtenant)
shall have the right and option (the "RENEWAL OPTION") to renew this Lease, by
written notice delivered to Landlord no later than twelve (12) months prior to
the expiration of the initial Lease Term, for an additional term (the "RENEWAL
TERM") of sixty (60) months under the same terms, conditions and covenants
contained in the Lease, except that (a) no abatements or other concessions, if
any, applicable to the initial Lease Term shall apply to the Renewal Term, (b)
the Base Rental shall be equal to the market rate for comparable office space
located in buildings comparable to the Building within a two (2) mile radius of
the Building as of the end of the initial Lease Term as reasonably determined by
Landlord, (c) Tenant shall have no option to renew this Lease beyond the
expiration of the Renewal Term; and (d) all leasehold improvements within the
Premises shall be provided in their then existing condition (on an "as is"
basis) at the time the Renewal Term commences.  Failure by Tenant to notify
Landlord in writing of Tenant's election to exercise the Renewal Option herein
granted within the time limits set forth for such exercise shall constitute a
waiver of such Renewal Option.  In the event Tenant elects to exercise the
Renewal Option as set forth above, Landlord shall, within thirty (30) days
thereafter, notify Tenant in writing of the proposed rental for the Renewal Term
(the "PROPOSED RENEWAL RENTAL").  Tenant shall within thirty (30) days following
delivery of the Proposed Renewal Rental by Landlord notify Landlord in writing
of the acceptance or rejection of the Proposed Renewal Rental.  If Tenant
accepts Landlord's proposal, then the Proposed Renewal Rental shall be the
rental rate in effect during the Renewal Term.  Failure of Tenant to respond in
writing during the aforementioned thirty (30) day period shall be deemed an
acceptance by Tenant of the Proposed Renewal Rental.  Should Tenant reject
Landlord's Proposed Renewal Rental during such thirty (30) day period, then
Landlord and Tenant shall negotiate during the thirty (30) day period commencing
upon Tenant's rejection of Landlord's Proposed Renewal Rental to determine the
rental for the Renewal Term.  In the event Landlord and Tenant are unable to
agree to a rental for the Renewal Term during said thirty (30) day period, then
the Renewal Option shall terminate and be null and void and the Lease shall,
pursuant to its terms and provisions, terminate at the end of the original Lease
Term.

       Upon exercise of the Renewal Option by Tenant and subject to the
conditions set forth hereinabove, the Lease shall be extended for the period of
such Renewal Term without the necessity of the execution of any further
instrument or document, although if requested by either party, Landlord and
Tenant shall enter into a written agreement modifying and supplementing the
Lease in accordance with the provisions hereof.  Any termination of the Lease
during the initial Lease Term shall terminate all renewal rights hereunder.  The
renewal rights of Tenant hereunder shall not be severable from the Lease, nor
may such rights be assigned or otherwise conveyed in connection with any
permitted assignment of the Lease.  Landlord's consent to any assignment of the
Lease shall not be construed as allowing an assignment of such rights to any
assignee.

                                RIGHT OF FIRST REFUSAL

       Provided that no event of default has ever occurred more than one time in
any consecutive twelve-month period, under any term or provision contained in
this Lease and no condition exists which with the passage of time or the giving
of notice or both would constitute an event of default pursuant to this Lease
and provided that Tenant has continuously occupied the Premises for the
Permitted Use during the Lease Term, Tenant (but not any assignee or subtenant)
shall have the right, subject to the terms and conditions set forth below, to
lease (i) the remainder of the sixth floor of the Building which Tenant is not
leasing under this Lease, and (ii) Suite 395 in the Building which suite
Landlord and Tenant agree contains 3,638 rentable square feet (the "RIGHT OF
FIRST REFUSAL SPACE") before it is leased to any third party.

       In the event any third party expresses interest in leasing all or any
portion of the Right of First Refusal Space during the Lease Term ("THIRD PARTY
INTEREST"), Landlord shall offer the entire Right of First Refusal Space to
Tenant upon the same terms, covenants and conditions as provided in the Lease
for the original Premises, except that (i) the rent for the Right of First
Refusal Space shall be the then prevailing market rate, as determined by
Landlord, for comparable office space located in the Building; (ii) Tenant shall
accept the Right of First Refusal Space "As Is"; and (iii) Tenant shall have no
further rights with respect to the Right of First Refusal Space.  If Tenant
notifies Landlord in writing of the acceptance of such offer within five (5)
days after Landlord has delivered such offer to Tenant, Landlord and Tenant
shall enter into a written agreement modifying and supplementing the Lease and
specifying that such Right of First Refusal Space accepted by Tenant is a part
of the Premises demised pursuant to the Lease for the remainder of the Lease
Term and any renewal thereof, if applicable and containing other appropriate
terms and conditions relating to the addition of the Right of First Refusal
Space to this Lease (including specifically any increase or adjustment of the
rent as a result of such addition).  In the event that Tenant does not notify
Landlord in writing of its acceptance of such offer in such five (5) day period,
then Tenant's rights under this paragraph with respect to the Right of First
Refusal Space shall terminate and Landlord shall thereafter be able to lease the
Right of First Refusal Space or any portion thereof to any third party.  Should
Tenant's rights regarding the Right of First Refusal terminate under this
paragraph and Landlord is thereafter unsuccessful in leasing all the Right of
First Refusal Space to a third party, Landlord shall not be obligated to offer
the Right of First Refusal Space to Tenant for six (6) months after the date
Tenant's rights were so terminated.  Any termination of the Lease shall
terminate all rights of Tenant with respect to the Right of First Refusal Space.
The rights of Tenant with respect to the Right of First Refusal Space shall not
be severable from the Lease, nor may such rights be assigned or otherwise
conveyed in connection with any permitted assignment of the Lease.  Landlord's
consent to any assignment of the Lease shall not be construed as allowing an
assignment or a conveyance of such rights to any assignee.  Nothing herein
contained should be construed so as to limit or abridge Landlord's ability to
deal with the Right of First Refusal Space or to lease the Right of First
Refusal Space to other tenants, Landlord's sole obligation being to offer, and
if such offer is accepted, to deliver the Right of First Refusal Space to Tenant
in accordance with this provision. The right of first refusal granted here is
subject to prior rights, of other tenants existing in the Building, which
include prior rights of first refusal and/or renewal rights. This right of
refusal is a continuing right of refusal and shall apply to any releasing of any
space even if Tenant previously had elected not to lease space pursuant to a
previous right of refusal.

       The Lease shall not be void or voidable, nor shall Landlord be liable to
Tenant for any loss or damage resulting from any delay in delivering possession
of the Right of First Refusal Space to Tenant, but abatement of the Base Rental
attributable to the Right of First Refusal Space from the date of Tenant's
acceptance of Landlord's offer with respect to the Right of First Refusal Space
to the date of actual delivery of the Right of First Refusal Space shall
constitute full settlement of all claims that Tenant might have against Landlord
by reason of the Right of First Refusal Space not being delivered upon the date
of Tenant's acceptance of Landlord's offer.
