W I T N E S S E T H: 1. DEFINITIONS: The following are definitions of some of the defined terms used in this Lease. The definition of other defined terms are found throughout this Lease. (a) "BUILDING" shall mean the office building located upon the real property (the "Property") described in EXHIBIT "A" attached hereto and incorporated herein together with all appurtenances thereto. (b) "BASE RENTAL" shall mean the following sums per month for each of the stated years of the Lease Term for a total of $2,569,378.79 during the Lease Term, all as adjusted pursuant to EXHIBIT "C" hereto: Commencement Date - April 30, 1998 $ 35,012.40 per month May 1, 1998 - April 30, 1999 $ 35,772.86 per month May 1, 1999 - April 30, 2000 $ 36,825.36 per month May 1, 2000 - April 30, 2001 $ 37,585.82 per month May 1, 2001 - April 30, 2002 $ 38,638.32 per month May 1, 2002 - March 31, 2003 $ 39,398.77 per month
The Base Rental due for the first month during the "LEASE TERM" (hereinafter defined) has been deposited with Landlord by Tenant contemporaneously with the execution hereof. (c) "BASIC COSTS" shall mean all direct and indirect costs and expenses incurred in connection with the Building as more fully defined in EXHIBIT "C" attached hereto. (d) "SECURITY DEPOSIT" shall mean: (1) An irrevocable, annually renewable letter of credit (the "SECURITY LETTER OF CREDIT") to the Landlord's benefit, on terms acceptable to Landlord, in the amount of $342,258.31, shall be delivered by Tenant to Landlord within five (5) days after execution of this Lease by both Landlord and Tenant or on the date Tenant first occupies the Premises, whichever is earlier. The Security Letter of Credit shall be held by Landlord as security for Tenant's obligations under this Lease. If Tenant does not renew the Security Letter of Credit and deliver to Landlord the original, renewed letter of credit (thereafter defined as the "SECURITY LETTER OF CREDIT") at least thirty (30) days before the end of the annual term of each annual Security Letter of Credit, on that date which is twenty-nine (29) days before the end of that year's Security Letter of Credit, Landlord may cash in that Security Letter of Credit and thereafter hold the cash as a deposit in lieu of the Security Letter of Credit. Such sum shall be held by Landlord, who shall have no obligation to account to Tenant for any interest thereon. In the last ten months of the Lease Term, Tenant may, at its option, redeem from Landlord the Security Letter of Credit by substituting for the Security Letter of Credit a sum of cash equal to the Base -Page 1- EXHIBIT 10.6 Rental due during the last twelve months of the Lease Term. If the Tenant chooses this option, the stated sum of cash shall be deemed to be the "SECURITY DEPOSIT". Each month thereafter, a portion of the Security Deposit shall be applied to the Base Rental due in each consecutive month. It is the parties' intention that at the end of the Lease Term the Security Deposit shall equal the Base Rental due for the last two months of the Lease Term. Landlord shall have no obligation to account to Tenant for interest on the Security Deposit; and (2) An additional, irrevocable, annual renewable Letter of Credit (the "IMPROVEMENT LETTER OF CREDIT") to Landlord's benefit, on terms acceptable to Landlord, in the amount of $381,414.62, shall be delivered by Tenant to Landlord on execution of this Lease. If Tenant does not renew the Improvement Letter of Credit and deliver to Landlord the original, renewed letter of credit (thereafter defined as the "IMPROVEMENT LETTER OF CREDIT") at least thirty (30) days before the end of the annual term of each annual Improvement Letter of Credit, on that date which is twenty-nine (29) days before the end of that year's Improvement Letter of Credit, Landlord may cash in that Improvement Letter of Credit and thereafter hold the cash as a deposit in lieu of the Improvement Letter of Credit. Such sum shall be held by Landlord, who shall have no obligation to account to Tenant for any interest thereon. The Improvement Letter of Credit shall expire on the date on which Tenant's accumulated payments of Basic Rental since the Commencement Date equal the total sum secured by the Improvement Letter of Credit. (e) "COMMENCEMENT DATE" shall mean the earlier of the date that Tenant actually occupies the Premises or July 1, 1997 (except as the same may be delayed pursuant to the provisions of Paragraph 3(a) hereof). (See Addendum, Section 4). (f) "LEASE TERM" shall mean a term commencing on the Commencement Date and continuing for sixty-nine (69) full calendar months (plus any partial calendar month in which the Commencement Date occurs). (g) "PREMISES" shall mean the suite of offices located within the Building and outlined on EXHIBIT "B" to this Lease. The Premises are stipulated for all purposes to contain 25,260 square feet of "Rentable Area" (as defined below).

The Rentable Area in the Building shall be deemed to be 84,094 square feet. The estimates of Rentable Area within the Premises and within the Building as set forth herein may be revised at Landlord's election if Landlord's architect determines such estimate to be inaccurate in any material degree after examination of the final drawings of the Premises and the Building. (See Addendum, Section 1). (i) "COMMON AREAS" shall mean those areas devoted to corridors, elevator foyers, mail rooms, restrooms, mechanical rooms, elevator mechanical rooms, janitorial closets, electrical and telephone closets, vending areas, and lobby areas (whether at ground level or otherwise), and other similar facilities provided for the common use or benefit of tenants generally and/or the public. -Page 2- EXHIBIT 10.6 (j) "SERVICE AREAS" shall mean those areas within the outside walls of the Building used for stairs, elevator shafts, flues, vents, stacks, pipe shafts and other vertical penetrations (but shall not include any such areas for the exclusive use of a particular tenant). (k) "BUILDING STANDARD", when used herein, shall mean the type, brand, quality and/or quantity of materials Landlord designates from time to time to be the minimum quality and/or quantity to be used in the Building or the exclusive type, grade, quality and/or quantity of material to be used in the Building and shall include, but not be limited to, the Building Standard Materials defined in the Work Letter Agreement attached hereto as EXHIBIT "D". (l) "MAXIMUM RATE", when used herein, shall mean the greatest of the rates of interest from time to time permitted under applicable federal and state law. To the extent of the applicability of Article 5069-1.04, as amended, Texas Revised Civil Statutes, the Maximum Rate shall be the highest permitted rate based upon the "indicated rate ceiling", but to the extent now or hereafter permitted by Texas law, Landlord may from time to time implement, withdraw and reinstate any ceiling as an alternative to the indicated rate ceiling, including the right to reinstate the indicated rate ceiling. (m) "PRIME RATE" shall mean the per annum interest rate announced by Texas Commerce Bank from time to time (whether or not charged in each instance) as its prime or base rate.

LEASE GRANT. Subject to and upon the terms herein set forth, Landlord leases to Tenant and Tenant leases from Landlord the Premises. 3. LEASE TERM. (a) Subject to and upon the terms and conditions set forth in this Lease, this Lease shall continue in force for the Lease Term. Notwithstanding the Commencement Date provided in Paragraph l(e) of this Lease, Tenant's obligation for the payment of rent and the Lease Term shall not commence until Landlord has substantially completed all work to be performed by Landlord as set forth in the Work Letter Agreement attached hereto as EXHIBIT "D"; provided, however, that if Landlord shall be delayed in substantially completing said work as a result of any of the following (a "DELAY"): -Page 3- EXHIBIT 10.6 (i) Tenant's failure to furnish information in accordance herewith or to respond to any request by Landlord for any approval or information within any time period prescribed, or if no time period is prescribed, then within three Business Days of such request; or (ii) Tenant's insistence on materials, finishes or installations other than Landlord's Building Standard after having first been informed by Landlord in writing at or before the time of delivery to Tenant of final construction pricing for Tenant's approval that such materials, finishes or installations will cause a Delay; or (iii) Tenant's changes in any plans and specifications; or (iv) The performance by a person, firm or corporation employed by Tenant in the completion of any work by said person, firm or corporation (all such work and such persons, firms or corporations being subject to the approval of Landlord); or (v) Any request by Tenant that Landlord delay the completion of any of Landlord's work; or (vi) Any breach or default by Tenant in the performance of Tenant's obligations under this Lease; or (vii) Any delay resulting from Tenant's having taken possession of the Premises prior to its being substantially completed, as defined below; or (viii) Any reasonably necessary displacement of any of Landlord's work from its place in Landlord's construction schedule resulting from any of the causes for Delay; or (ix) Any other delay chargeable to Tenant, its agents, employees or independent contractors; then the commencement of the Lease Term and the payment of rent shall be accelerated by the number of days of such Delay but in no event shall such commencement be prior to the Commencement Date stipulated in Paragraph 1(e) hereof. The Premises shall be deemed to be substantially completed on the date that Landlord's architect reasonably determines that all work to be performed by Landlord pursuant to this Lease has been performed other than punchlist items. The term "punchlist items" as used herein shall mean any details of construction, mechanical adjustment or other matter, the noncompletion of which does not materially interfere with Tenant's use of the Premises. The abatement of rent shall be Tenant's sole remedy and shall constitute full settlement of all claims that Tenant might otherwise have against Landlord by reason of the Premises not being ready for occupancy by Tenant on the Commencement Date. If for any reason Tenant takes possession of the Premises prior to substantial completion, except as set forth in the next sentence, Tenant's obligation to pay rent shall commence upon the date Tenant takes possession of the Premises and Tenant shall indemnify and hold Landlord harmless from any liability as a result of Tenant's early occupancy of the Premises. Tenant shall have access to the Premises five (5) days before the Commencement Date to move in furniture and prepare for opening Tenant's business; provided (i) that Tenant shall not conduct business from the Premises until the Commencement Date and (ii) that Landlord and Tenant prepare a final -Page 4- EXHIBIT 10.6 punchlist before Tenant shall have such access. Landlord's determination of the Commencement Date shall be final and binding on all parties for all purposes hereof, including, without limitation, determination of the date of commencement of the Lease Term and of Tenant's obligation to pay rent hereunder. (See Addendum, Sections 2 and 3). (b) The taking of possession of the Premises by Tenant shall be conclusive evidence against Tenant that, except for the completion of any items which Landlord stipulates in writing are remaining to be done or corrected by Landlord, (i) Tenant warrants and represents to Landlord that it has conducted its own independent investigation of the Premises and that the Premises are suitable for the purpose for which the same are leased, (ii) the Property and the Building and each and every part and appurtenance thereof are in good and satisfactory condition, except for any defect which is not discoverable upon a reasonable inspection, and (iii) Tenant waives any defects in the Premises and its appurtenances and in all other parts of the Building and the appurtenances thereto, except for any defect which is not discoverable upon a reasonable inspection. If Tenant intends to vacate the Premises at the end of the Lease Term, Tenant will give Landlord ninety (90) days prior written notice of such intent to vacate the Premises. 4. USE. The Premises shall be used for office purposes (the "PERMITTED USE") and for no other purpose. Neither Landlord nor its agents or employees have made any representation or warranty as to the suitability of the Premises for the conduct of Tenant's business. 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 reasonable 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 unreasonably 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 covenants not to introduce any toxic material into or near Building. Without limiting the generality of the foregoing, Tenant shall not store, use or dispose of any toxic material in or near the Building. Tenant shall comply with all applicable federal, state, and local laws or ordinances pertaining to the storage, use or disposal of any toxic material. 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. Tenant will not conduct or permit to be conducted any sale by auction on the Premises. (See Addendum, Section 5). 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 -Page 5- EXHIBIT 10.6 "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 Landlord's 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 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, 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. (d) See additional provisions regarding Base Rental in Paragraph 6. 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, except as set forth later in this paragraph, 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 -Page 6- EXHIBIT 10.6 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 may 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, the level and quality of services typically provided by Landlords of office buildings comparable to the Building within a three mile radius 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 comparable office space in such area without additional charge.

(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. -Page 7- EXHIBIT 10.6 (g) Access control to the Building during other than Normal Business Hours shall be provided in such form as Landlord deems appropriate. 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. (See Addendum, Section 6). 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. (See Addendum, Section 8). Notwithstanding anything to the contrary set forth in this Lease, if there is any material slow-down, interruption or stoppage of any of the services required to be provided by Landlord pursuant to this Lease, and if Landlord has failed to commence to cure or remedy such problem within ten (10) days after Tenant's prior written notice thereof, or if Landlord should fail thereafter to proceed diligently to remedy such problem, then provided that the problem has a material adverse effect on the habitability of the Premises or a portion thereof and Tenant has ceased to use or occupy the portion of the Premises affected, Tenant shall have the right to abate rent by submitting to binding arbitration. 8. IMPROVEMENTS TO BE MADE BY LANDLORD. Except as otherwise provided in the Work Letter Agreement attached hereto as Exhibit "W" 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. (See Addendum, Section 7). 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, or place signs on the Premises which are -Page 8- EXHIBIT 10.6 visible from outside the Premises, without first obtaining the written consent of Landlord in each such instance. If Landlord gives its consent, no such alterations will proceed without Landlord's prior written approval of (i) Tenant's contractor, (ii) certificates of insurance by Tenant's contractor for public liability and automobile liability and property damage insurance as set forth in Paragraph 16, and (iii) detailed plans and specifications for such work. 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 personalty 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 seven (7) 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 may, 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 Landlord approves the plans or such installments (the "REQUIRED REMOVABLES") at Tenant's sole cost. 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. Landlord may also require Tenant to provide Landlord, at Tenant's sole cost and expense, a payment and performance bond in form acceptable to Landlord, in a principal amount not less than one and one-half times the estimated cost of such alterations, to insure Landlord against any liability for mechanic's or materialman's liens and to insure completion of the work. Lessor will have the right to construct or permit construction of tenant improvements in or about the Building for existing and new tenants and to alter any public areas in and around the Property. Notwithstanding anything which may be contained in this Lease, Tenant understands this right of Landlord and agrees that such construction will not be deemed to constitute a breach of this Lease by Landlord and Tenant waives any such claim which it might have arising from such construction. Tenant will not make repairs to the Premises at the cost of Landlord, whether by deduction of rent or otherwise and will not vacate the Premises or terminate the Lease with abatement or termination of rent because repairs are not made. If during the Lease Term, any alteration, addition or change to the Premises is required by legal authorities, Tenant, at its sole expense, shall promptly make same. Landlord will not be liable for any failure to make any repairs or perform any maintenance and there will be no abatement of rent, nor liability of Landlord by reason of any injury to or interference with Tenant's business arising from the making or failure to make any repair, alteration or improvement in or to any portion of the Premises or to Tenant's fixtures, appurtenances and equipment. 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 may consent upon such conditions as Landlord elects (including the requirement that submeters be installed at Tenant's expense). However, Tenant shall have the right to install its own HVAC system (subject to Landlord s approval of the size and location of such system) at Tenant's expense which system shall be separately metered and for which Tenant shall be fully responsible, both for the monthly utility charges therefor and for the maintenance and repair thereof. Tenant additionally shall pay to Landlord an administrative fee equal to five percent (5%) of (i) any utility charges for this additional HVAC system and (ii) any repairs thereof which Landlord must perform if Tenant does not. At the end of the Lease Term, the HVAC system which Tenant installs shall become the property Landlord (subject to Landlord s approval of size and location of such system). -Page 9- EXHIBIT 10.6 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 (to tenants only during last year of 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. Landlord will at all times have and retain a key with which to unlock all of the doors in, upon and about the Premises, excluding Tenant's vaults, safes and filing cabinets. Tenant will not alter any lock or install a new or additional lock or any bolt on any door of the Premises without the prior written consent of Landlord, which will not be unreasonably withheld. If Landlord gives its consent, such work shall be undertaken by a locksmith approved by Landlord, at Tenant's sole cost, and Tenant will furnish Landlord with a key. Landlord retains the right to charge Tenant for restoring any altered doors to their condition prior to the installation of the new or additional locks. 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 has a financial strength equal to or greater than Tenant's. 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 sixty (60) 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 -Page 10- EXHIBIT 10.6 Landlord, and Tenant shall bear all costs and expenses incurred by Landlord in connection with the review and approval of such documentation. Landlord shall not withhold its approval of a proposed assignment or sublease unreasonably, provided Landlord approves the financial strength of, and use of the Premises proposed by, the proposed assignee or sublessee. Landlord shall have no right to terminate this Lease if Tenant assigns or subleases the Premises to an affiliate of Tenant, provided that the financial strength of the affiliate is equal to or greater than Tenant's and provided that Tenant shall remain liable under this Lease. An "AFFILIATE" shall be defined as any entity which owns at least fifty-one percent (51%) of the equity and control of Tenant or an entity in which Tenant owns at least fifty-one percent (51%) of the equity and control. (c) All cash or other proceeds of any assignment or sublease 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 or subtenant and require that from that time forward all payments made pursuant to the assignment or sublease shall be made directly to the Landlord. Any assignee or subtenant of Tenant's interest in this Lease (all such assignees or subtenants 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. (See Addendum, Section 10). (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. Notwithstanding the foregoing, Tenant shall have the right to add investors, change investors or otherwise change its ownership structure, including offering interests in Tenant publicly, and such changes shall not be an assignment requiring Landlord's consent so long as such changes do not decrease Tenant's financial strength, in Landlord's reasonable opinion and as long as Tenant gives Landlord written notice of such change in Tenant's structure at least 30 days before such change is effective. -Page 11- EXHIBIT 10.6 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 such amounts as Landlord elects. 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 fire 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, -Page 12- EXHIBIT 10.6 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 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 to the extent required by law, provided that Tenant shall indemnify and hold harmless Landlord, its employees, agents, successors and assigns from any and all claims made by Tenant's employees regarding such worker's compensation or employer's liability issues. (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 parry, its agents or employees, if any such loss or damage is covered by insurance benefitting 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 nor any of its 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 its officers, directors, employees and -Page 13- EXHIBIT 10.6 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 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. (See Addendum, Section 11). 18. 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. 19. 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 shall, in Landlord's sole opinion, be required (whether or not the Premises shall have been damaged by such casualty) or in the event there is less than two (2) years of the Lease Term remaining or in the event any mortgagee of Landlord's should require that the insurance proceeds payable as a result of a casualty be applied to the payment of the mortgage debt or in the event of any material uninsured loss to 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 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 Budding, 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 which Landlord is not obligated to restore as set forth above. Except as set forth above, all cost and expense of reconstructing the Premises shall be borne 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 Promises. 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 -Page 14- EXHIBIT 10.6 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. 20. 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. 21. 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. 22. EVENTS OF DEFAULT/REMEDIES. (a) The following events shall be deemed to be events of default under this Lease: (i) Tenant shall fail to pay within five days of the due date any Base Rental or other rent payable by Tenant to Landlord under this Lease (hereinafter sometimes referred to as a "MONETARY DEFAULT"). (ii) Any failure by Tenant (other than a Monetary Default) to comply with any term, provision or covenant of this Lease, which failure is not cured within twenty (20) days after delivery to Tenant of notice of the occurrence of such failure or if such failure is not reasonably susceptible of being cured within such twenty (20) day period, Tenant shall fail to commence the curing thereof within such twenty (20) day period, or having commenced the curing thereof, Tenant shall fail to diligently pursue the curing of such default with reasonable diligence to completion. (iii) Tenant or any Guarantor shall become insolvent, or shall make a transfer in fraud of creditors, or shall commit an act of bankruptcy or shall make an assignment -Page 15- EXHIBIT 10.6 for the benefit of creditors, or Tenant or any Guarantor shall admit in writing its inability to pay its debts as they become due. (iv) Tenant or any Guarantor shall file a petition under any section or chapter of the United States Bankruptcy Code, as amended, pertaining to bankruptcy, or under any similar law or statute of the United States or any State thereof, or Tenant or any Guarantor shall be adjudged bankrupt or insolvent in proceedings filed against Tenant or any Guarantor thereunder; or a petition or answer proposing the adjudication of Tenant or any Guarantor as a bankrupt or its reorganization under any present or future federal or state bankruptcy or similar law shall be filed in any court and such petition or answer shall not be discharged or denied within sixty (60) days after the filing thereof. (v) A receiver or trustee shall be appointed for all or substantially all of the assets of Tenant or any Guarantor or of the Premises or of any of Tenant's property located thereon in any proceeding brought by Tenant or any Guarantor, or any such receiver or trustee shall be appointed in any proceeding brought against Tenant or any Guarantor and shall not be discharged within sixty (60) days after such appointment or Tenant or such Guarantor shall consent to or acquiesce in such appointment. (vi) The leasehold estate hereunder shall be taken on execution or other process of law in any action against Tenant. (vii) Tenant shall abandon or vacate any substantial portion of the Premises without the prior written permission of Landlord for a period longer than 365 consecutive days during the Lease Term. If Tenant or any other person acting on Tenant's behalf has removed, is removing or has made preparations to remove (other than in the normal course of business) goods, equipment, fixtures or other property from the Premises in amounts substantial enough to indicate a probable intent to abandon or vacate the Premises without the prior written permission of Landlord, Tenant's abandonment of the Premises shall be deemed conclusively established for all purposes. The provisions of the foregoing sentence shall supersede the provisions of the Texas Property Code. (viii) Tenant shall fail to take possession of and occupy the Premises within sixty (60) days following the Commencement Date and thereafter continuously conduct its operations in the Premises for the Permitted Use as set forth in Paragraph 4 hereof. (ix) The liquidation, termination, dissolution, forfeiture of right to do business or death of Tenant or any Guarantor. (b) Upon the occurrence of any event or events of default under this Lease, whether enumerated in this Paragraph or not, Landlord shall have the option to pursue any one or more of the following remedies without any notice (except as expressly prescribed herein) or demand for possession whatsoever (and without limiting the generality of the foregoing, Tenant hereby specifically waives notice and demand for payment of rent or other obligations due and waives any and all other notices or demand requirements imposed by applicable law): (i) Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord. If Tenant fails to surrender the Premises upon termination of -Page 16- EXHIBIT 10.6 the Lease hereunder, Landlord may without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying said Premises, or any part thereof, by force, if necessary, without being liable for prosecution or any claim of damages therefor, and Tenant hereby agrees to pay to Landlord on demand the amount of all loss and damage which Landlord may suffer by reason of such termination, whether through inability to relet the Premises on satisfactory terms or otherwise, specifically including but not limited to all Costs of Reletting (hereinafter defined) and any deficiency that may arise by reason of any reletting. If such termination is caused by the failure to pay rent and/or the abandonment of any substantial portion of the Premises, Landlord may elect, by sending written notice thereof to Tenant, to receive liquidated damages in an amount equal to the Base Rental and other rent payable hereunder for the month during which the Lease is terminated times the lesser of (A) twelve (12) or (B) the number of months remaining in the Lease Term as of the date of such failure to pay rent and/or abandonment of any substantial portion of the Premises. Such liquidated damages shall be in lieu of the payment of loss and damage Landlord may suffer by reason of such termination as provided in the preceding sentence but shall not be in lieu of or reduce in any way any amount (including accrued rent) or damages due to breach of covenant (whether or not liquidated) payable by Tenant to Landlord which is accrued and outstanding at the time of the termination of the Lease. (ii) Enter upon and take possession of the Premises and expel or remove Tenant or any other person who may be occupying said Premises, or any part thereof, by force, if necessary, without having any civil or criminal liability therefor and without terminating this Lease. Landlord may (but shall be under no obligation to) relet the Premises or any part thereof for the account of Tenant, in the name of Tenant or Landlord or otherwise, without notice to Tenant for such term or terms which may be greater or less than the period which would otherwise have constituted the balance of the Lease Term and on such conditions (which may include concessions or free rent) and for such uses as Landlord in its absolute discretion may determine, and Landlord may collect and receive any rents payable by reason of such reletting. Tenant agrees to pay Landlord on demand all Costs of Reletting and any deficiency that may arise by reason of such reletting. Landlord shall not be responsible or liable for any failure to relet the Premises or any part thereof or for any failure to collect any rent due upon any such reletting. No such re-entry or taking of possession of the Premises by Landlord shall be construed as an election on Landlord's part to terminate this Lease unless a written notice of such termination is given to Tenant. (iii) Enter upon the Premises by force if necessary without having any civil or criminal liability therefor, and do whatever Tenant is obligated to do under the terms of this Lease and Tenant agrees to reimburse Landlord on demand for any expense which Landlord may incur in thus affecting compliance with Tenant's obligations under this Lease together with interest at the lesser of a per annum rate equal to (i) the Maximum Rate or (ii) the Prime Rate plus five percent (5%) and Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from such action, whether caused by the negligence of Landlord or otherwise. (iv) In order to regain possession of the Premises and to deny Tenant access thereto, Landlord or its agent may, at the expense and liability of the Tenant, alter or -Page 17- EXHIBIT 10.6 change any or all locks or other security devices controlling access to the Premises without posting or giving notice of any kind to Tenant. Landlord shall have no obligation to provide Tenant a key or grant Tenant access to the Premises so long as Tenant is in default under this Lease. Tenant shall not be entitled to recover possession of the Premises, terminate this Lease, or recover any actual, incidental, consequential, punitive, statutory or other damages or award of attorneys' fees, by reason of Landlord's alteration or change of any lock or other security device and the resulting exclusion from the Premises of the Tenant or Tenant's agents, servants, employees, customers, licensees, invitees or any other persons from the Premises. Landlord may, without notice, remove and either dispose of or store, at Tenant's expense, any property belonging to Tenant that remains in the Premises after Landlord has regained possession thereof. Any such property of Tenant not retaken by Tenant from Landlord's storage within 30 days after removal from the Premises shall, at Landlord's option. be deemed conveyed by Tenant to Landlord under this Lease as by a bill of sale without further payment or credit by Landlord to Tenant. Tenant acknowledges that the provisions of this subparagraph of this Lease supersedes die Texas Property Code and Tenant farther warrants and represents that it hereby knowingly waives any rights it may have thereunder. (v) Terminate this Lease by giving Tenant written notice thereof, in which event, Tenant shall pay to Landlord the sum of (i) all rent accrued hereunder through the date of termination, (ii) all Costs of Reletting, and (iii) an amount equal to (A) the total rent that Tenant would have been required to pay for the remainder of the Lease Term discounted to present value minus; (B) the then present fair rental value of the Premises for such period, similarly discounted. (c) For purposes of this Lease, the term "COSTS OF RELETTING" shall mean all costs and expenses incurred by Landlord in connection with the reletting of the Promises, including without limitation the cost of cleaning, renovation, repairs, decoration and alteration of the Premises for a new tenant or tenants, advertisement, marketing, brokerage and legal fees, the cost of protecting or caring for the Premises while vacant, the cost of removing and storing any property located on the Premises, any increase in insurance premiums caused by the vacancy of the Premises, costs of carrying the Premises such as taxes, insurance premiums, utilities and security precautions, any unearned brokerage commissions paid in connection with this Lease, parking fees or occupancy taxes due under the Lease, reimbursement of any previously waived Base Rental, Basic Costs, free rent, or reduced rental rate, and any concession made or paid by Landlord to the benefit of Tenant in consideration of this Lease including, but not limited to, any moving allowances, contributions or payments by Landlord for tenant improvements or build-out allowances, or assumptions by Landlord of any of Tenant's previous lease obligations and any other out-of-pocket expenses incurred by Landlord including tenant inducements such as the cost of moving the new tenant or tenants and the cost of assuming any portion of the existing lease(s) of the new tenant(s). (d) Except as otherwise herein provided, no repossession or re-entering on the Premises or any part thereof pursuant to Paragraph 22(b) hereof or otherwise shall relieve Tenant or any Guarantor of its liabilities and obligations hereunder, all of which shall survive such repossession or re-entering. Notwithstanding any such repossession or re-entering on the Premises or any part thereof by reason of the occurrence of an event of default, Tenant will pay to Landlord the Base Rental and other rent or other sum required to be paid by Tenant pursuant to this Lease. -Page 18- EXHIBIT 10.6 (e) No right or remedy herein conferred upon or reserved to Landlord is intended to be exclusive of any other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing by agreement, applicable law or in equity. In addition to other remedies provided in this Lease, Landlord shall be entitled, to the extent permitted by applicable law, to injunctive relief in case of the violation, or attempted or threatened violation, of any of the covenants, agreements, conditions or provisions of this Lease, or to a decree compelling performance of any of the other covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to Landlord at law or in equity. Forbearance by Landlord to enforce one or more of the remedies herein provided upon an event of default shall not be deemed or construed to constitute a waiver of such default. (f) This Paragraph 22 shall be enforceable to the maximum extent such enforcement is not prohibited by applicable law, and the unenforceability of any portion thereof shall not thereby render unenforceable any other portion. To the extent any provision of applicable law requires some action by Landlord to evidence or effect the termination of this Lease or to evidence the termination of Tenant's right of occupancy, Tenant and Landlord hereby agree that written notice by Landlord to any of Tenant's agents, servants or employees, which specifically sets forth Landlord's intention to terminate, shall be sufficient to evidence and effect the termination herein provided for. 23. 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. (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. -Page 19- EXHIBIT 10.6 24. 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 Estelle 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. 25. 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 Base Rental 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 -Page 20- EXHIBIT 10.6 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; (h) 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(c)(2) of the Bankruptcy Code. 26. 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. 27. SUBSTITUTION. [Intentionally Omitted] 28. 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 possession pursuant to Paragraph 22(b) hereof, Tenant shall, throughout the entire holdover period, pay rent equal to 150% of the sum of the Base Rental and 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. -Page 21- EXHIBIT 10.6 29. SUBORDINATION TO MORTGAGE. Tenant accepts this Lease 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. This clause shall be self-operative and no further instrument of subordination shall be required. However, 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. Landlord is hereby irrevocably vested with full power and authority to subordinate this Lease to any mortgage, deed of trust or other lien now existing or hereafter placed upon the Premises, or the Building and/or the Property if Tenant does not properly execute and return to Landlord the documents required to further evidence such subordination within ten (10) days after the documents are delivered to Tenant. The terms of this Lease are subject to approval by the Landlord's existing Lender(s) and any lender(s) who, at the time of the execution of this Lease, have committed or are considering committing to Landlord to make a-loan secured by all or any portion of the Property, and such approval is a condition precedent to Landlord's obligations hereunder. 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. (See Addendum, Section 12). 30. 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 non-prevailing party agrees to pay the prevailing party's reasonable attorneys' fees. 31. NOTICE. Any notice in this Lease provided for must, unless otherwise expressly provided herein, be in writing, and may, unless otherwise in this Lease expressly provided, be given or be served by depositing the same in the United States mail, postage paid and certified with return receipt requested, or by prepaid telegram, when appropriate, addressed to the party to be notified at the address stated in this Lease or such other address notice of which has been given to the other party or by delivering the same in person to such party or an officer or partner of such party. Notice deposited in the mail in the manner hereinabove described shall be effective as of the date it is so deposited. 32. SEVERABILITY. If any term or provision of this Lease, or the application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and enforced to the fullest extent permitted by law. 33. RECORDATION. Tenant agrees not to record this Lease or any memorandum hereof. 34. GOVERNING LAW. This Lease and the rights and obligations of the parties hereto shall be interpreted, construed, and enforced in accordance with the laws of the State of Texas. -Page 22- EXHIBIT 10.6 35. FORCE MAJEURE. Whenever a period of time is herein prescribed for the taking of any action by Landlord, Landlord shall not be liable or responsible for, and there shall be excluded from the computation of such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, governmental laws, regulations or restrictions, or any other cause whatsoever beyond the control of Landlord. 36. TIME OF PERFORMANCE. Except as expressly otherwise herein provided, with respect to all required acts of Tenant, time is of the essence of this Lease. 37. TRANSFERS BY LANDLORD. Landlord shall have the right to transfer and assign, in whole or in part, all of its rights and obligations hereunder and in the Building and Property referred to herein, and in such event and upon such transfer Landlord shall be released from any further obligations hereunder, and Tenant agrees to look solely to such successor in interest of Landlord for the performance of such obligations. 38. COMMISSIONS. Landlord and Tenant hereby indemnify and hold each other harmless against any loss, claim, expense or liability with respect to any commissions or brokerage fees claimed on account of the execution and/or renewal of this Lease due to any action of the indemnifying party, except that Landlord will pay the commissions to the Tenant's broker in accordance with a separate commission agreement. 39. JOINT AND SEVERAL LIABILITY. If there is more than one Tenant, or if the Tenant as such is comprised of more than one person or entity, the obligations hereunder imposed upon Tenant shall be joint and several obligations of all such parties. 40. AUTHORITY. In the event Tenant is a corporation (including any form of professional association), partnership (general or limited), or other form of organization other than an individual, then each individual executing or attesting this Lease on behalf of Tenant hereby covenants, warrants and represents: (i) that such individual is duly authorized to execute or attest and deliver this Lease on behalf of Tenant in accordance with the organizational documents of Tenant; (ii) that this Lease is binding upon Tenant; (iii) that Tenant is duly organized and legally existing in the state of its organization, and is qualified to do business in the State of Texas; (iv) that upon request, Tenant will provide Landlord with true and correct copies of all organizational documents of Tenant. and any amendments thereto; and (v) that the execution and delivery of this Lease by Tenant will not result in any breach of, or constitute a default under any mortgage, deed of trust, lease, loan, credit agreement, partnership agreement or other contract or instrument to which Tenant is a party or by which Tenant may be bound. If Tenant is a corporation, Tenant will, prior to the Commencement Date, deliver to Landlord a copy of a resolution of Tenant's board of directors authorizing or ratifying the execution and delivery of this Lease, which resolution will be duly certified to Landlord's satisfaction by the secretary or assistant secretary of Tenant. 41. FINANCIAL CONDITION OF TENANT. Tenant acknowledges that the financial capability of Tenant to perform its obligations hereunder is material to Landlord and that Landlord would not enter into this Lease but for its belief, based on its review of Tenant's financial statements, that Tenant is capable of performing such financial obligations. Tenant hereby represents, warrants and certifies to Landlord that its financial statements are true and correct in all material respects. 42. EFFECT OF DELIVERY OF THIS LEASE. Landlord has delivered a copy of this Lease to Tenant for Tenant's review only, and the delivery hereof does not constitute an offer to Tenant or option. This -Page 23- EXHIBIT 10.6 Lease shall not be effective until an original of this Lease executed by both Landlord and Tenant and this Lease has been approved by Landlord's mortgagee, Landlord and Tenant hereby agree that Landlord will be entitled to immediately endorse and cash Tenant's good faith rent and the Security Deposit check(s) accompanying this Lease when the Lease is executed by both Tenant and Landlord. It is further agreed and understood that such action will not guarantee acceptance of this Lease by Landlord, but, in the event Landlord does not accept this Lease, such deposits will be refunded in full to Tenant. 43. ENTIRE AGREEMENT. This Lease Agreement, including the following Exhibits: Exhibit A - Property Description Exhibit B - Outline and Location of Premises Exhibit C - Payment of Excess Basic Cost Exhibit D - Work Letter Agreement Exhibit D-1 - Building Standard Materials Exhibit D-2 - Tenant Improvement Allowance Exhibit E - Parking Exhibit F - Certificate of Insurance for Tenant Exhibit G - [Intentionally Omitted] Exhibit H - Rules and Regulations Exhibit I - Renewal Option Addendum Roof License Agreement constitute the entire agreement between the parties hereto with respect to the subject matter of this Lease.

All understandings and agreements heretofore had between the parties are merged in this Lease which alone fully and completely expresses the agreement of the parties, neither party relying upon any statement or representation not embodied in this Lease. 44. LANDLORD'S LIEN. In addition to any statutory lien for rent in Landlord's favor, Landlord (the secured party for purposes hereof) shall have and Tenant (the debtor for purposes hereof) hereby grants to Landlord, subject to the last sentence of this paragraph, a continuing security interest for all Base Rental, rent and other sums of money becoming due hereunder from Tenant, upon all goods, wares, equipment, fixtures, furniture, inventory, accounts, contract rights, chattel paper and other personal property of Tenant situated on the Premises subject to this Lease being described as Suite 500 of the Building, located in Dallas, Dallas County, Texas (a description of the property in and upon which the Premises is located and an outline of the Premises are attached hereto as EXHIBIT "A" and EXHIBIT "B" respectively), and such property shall not be removed therefrom without the consent of Landlord until all arrearages in rent as well as any and all other sums of money then due to Landlord hereunder shall first have been paid and discharged. Fixtures located at the Premises and products of collateral are also covered hereby by the filing hereof in the real property records of Dallas County, Texas. In the event of a default under this Lease, Landlord shall have, in addition to any other remedies provided herein or by law, all rights and remedies under the Uniform Commercial Code, including without limitation the right to sell the property described in this Paragraph at public or private sale upon ten (10) days notice to Tenant which notice Tenant hereby agrees is adequate and reasonable. Tenant hereby agrees to execute such other instruments necessary or desirable in Landlord's discretion to perfect the security interest hereby created. Any statutory lien for rent is not hereby waived, the express contractual lien herein -Page 24- EXHIBIT 10.6 granted being in addition and supplementary thereto. Landlord and Tenant agree that this Lease and the security interest granted herein serve as a financing statement and a copy or photographic or other reproduction of this Paragraph of this Lease may be filed of record by Landlord and have the same force and effect as the original. Tenant warrants and represents that the collateral subject to the security interest granted herein is not purchased or used by Tenant for personal, family or household purposes. Tenant further warrants and represents to Landlord that the lien granted herein constitutes a first and superior lien and that Tenant will not allow the placing of any other lien upon any of the property described in this Paragraph without the prior written consent of Landlord.

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 1997, grossed up to reflect ninety-five percent (95%) occupancy for the Building. Basic Costs will be calculated in years subsequent to 1997 in a manner consistent with industry standards with the gross-up consistently applied in all years so that increases in Basic Costs will result solely from increases and not from different methods of calculation unless a change in method of calculation is to more accurately meet industry standards. 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 1 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 end of each calendar year during Tenant's occupancy Landlord shall furnish 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, at its expense, shall have the right no more frequently than once per calendar year, within 90 days after receipt by Tenant of each applicable annual reconciliation of Basic Costs, 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. 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 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. -Page 28- EXHIBIT 10.6 (b) All 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.

(f) Charges for all utilities including but not limited to water, sewer and electricity, but excluding those charges for which tenants are individually responsible. (g) Taxes, including (i) all real estate taxes and assessments on the Property, the Building or the Premises, and taxes and assessments levied in substitution or supplementation in whole or in part of such taxes, (ii) all personal property taxes for the Building's personal property, including license expenses, (iii) all taxes imposed on services of Landlord's agents and employees, and (iv) all other taxes, fees or assessments now or hereafter levied by any governmental authority on the Property, the Building or its contents or on the operation and use thereof (except as relate to specific tenants), but excluding income taxes.

(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. If Tenant fails to furnish any such information on or before June 13, 1997 or fails to approve layout, drawings or plans within five (5) Business Days after written request, Tenant agrees to pay on demand all costs and expenses and increased unit prices incurred by Landlord on account of Tenant's failure to furnish such information and approved drawings within such prescribed times and any scheduled dates for completion of the Tenant Improvements shall be extended day-for-day for the delay caused by Tenant. 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 or designer. Landlord shall bear the cost of the initial space planning drawings, to include one revision, which shall be prepared by Landlord's architect or designer. Unless otherwise provided in EXHIBIT "D-2", Tenant shall pay for additional space planning services beyond those specified above, 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 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 for 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 (whether paid to independent contractors or the five percent (5%) fee charged by Landlord for acting as a general contractor), 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 -Page 31- EXHIBIT 10.6 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, Tenant shall be chargeable with one day of Delay for each day thereafter until Tenant provides to Landlord in writing its approval of a 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, but prior to occupancy of the Premises by Tenant, 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. (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 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 which event Tenant shall be chargeable with a Delay in completion of the Premises resulting therefrom in accordance with Paragraph 3(a) of the Lease. 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 or designer, but at least shall be of Building Standard quality. Landlord shall notify Tenant of substantial completion of the Tenant Improvements. -Page 32- EXHIBIT 10.6 8. Any changes to Tenant's plans and specifications required by any governing Authority to conform to local, state or federal laws will be at the sole cost of Tenant, in addition to any other previously agreed upon improvement costs. 9. Prior to the commencement of construction of the Tenant Improvements, Tenant shall provide Landlord the Improvement Letter of Credit. 10. Tenant's Allowance (as defined in Exhibit D-2) also shall be applied to the costs of permits and fees paid to the City of Addison and a management fee of five percent (5%) of the total amount of the Tenant Improvements to compensate Landlord's agent for managing the construction of the Tenant Improvements and assisting in getting appropriate permits. 11. Any other language in this Exhibit D notwithstanding, the Tenant Improvements shall be constructed by one of the twenty general contractors previously approved by Landlord or by one general contractor of Tenant's choice, provided that this latter contractor meets the insurance and reference requirements of Landlord. A minimum of three bids to construct the Tenant Improvements will be received. Tenant shall have the right to review the bids and be involved with Landlord in the selection of the general contractor to perform the work. 12. Tenant shall have the option to utilize any items currently in place in the Premises. 13. In the event The Staubach Company acts as a project manager on behalf of Tenant, any cost of that service may be paid from the Allowance or may be paid by Tenant directly. -Page 33- EXHIBIT 10.6 EXHIBIT "D-1" 13.

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.

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. -Page 41- EXHIBIT 10.6 ADDENDUM This Addendum is to be attached to and made a part of that certain office Lease (the "LEASE") dated May 30, 1997, between 14850 Quorum Associates, Ltd.
