During the Term, Tenant shall have the right to use, in common with others and in accordance with the Rules and Regulations, the Common Areas. Section 2.02. Provided that Tenant fully and timely performs all the terms of this Lease on Tenant's part to be performed, including payment by Tenant of all Rent, Tenant shall have, hold and enjoy the Premises during the Term without hindrance or disturbance from or by Landlord; subject, however, to all of the terms, conditions and provisions of any and all ground leases, deeds to secure debt, mortgages, governmental laws, easements, protective covenants, and other encumbrances now or hereafter affecting the Premises, or the Project. ARTICLE 3 TERM; COMMENCEMENT DATE; DELIVERY AND ACCEPTANCE OF PREMISES Section 3.01. The Commencement Date for the Primary Premises shall be one hundred twenty (120) days following the delivery of the Premises in Tenant Finish Ready Condition as set forth on Attachment 2 to Exhibit "C, provided that the Commencement Date shall not occur until Landlord has substantially completed the Project, and completed the Premises in Base Premises Condition (collectively called "Landlord's Construction"). Landlord shall deliver the Premises to Tenant in Tenant Finish Ready Condition for construction of the Leasehold Improvements sixty (60) days prior to the estimated date Landlord will substantially complete the Premises in Base Premises Condition (defined in Exhibit C). The Commencement Date for the Secondary Premises shall be the first anniversary of the Commencement Date (the "Secondary Premises Commencement Date"). Section 3.02. Landlord shall cause the Building Commencement Date to occur as soon as possible in the exercise of Landlord's reasonable business judgement, but not later than forty-five (45) days following the date this Lease is signed by Landlord and Tenant. If Landlord shall fail to commence construction of the Building within such 45 day period, Tenant shall so notify Landlord and Landlord shall immediately commence construction. If following such notice, Landlord shall fail to commence construction, Tenant may terminate this Lease. Landlord shall substantially complete Landlord's Construction no later than the Substantial Completion Date. Landlord's Construction shall be deemed "substantially complete" when all of the following conditions have been met: (i) the Premises have been completed in Base Premises Condition (defined in Exhibit C), and (ii) Landlord has substantially completed the Project in substantial accordance with the Building Plans (defined in Exhibit C) and has received final or temporary certificates of occupancy so that Tenant has the right to use the Common Areas of the Building, the Parking Facilities, and the Common Areas of the Project. In the event Landlord fails to substantially complete Landlord's Construction on or before the Substantial Completion Date, the Tenant shall so notify the Landlord and the Landlord shall substantially complete Landlord's Construction same as soon as possible. The failure to substantially complete Landlord's 2 Construction within thirty (30) days following the Substantial Completion Date shall be a Base Condition Default and shall entitle the Tenant to the following rights: (a) If such Base Condition Default is not cured on or before thirty days following the Substantial Completion Date, but is cured no later than ninety (90) days following the Substantial Completion Date, then the Commencement Date shall be delayed until the date Landlord substantially completes Landlord's Construction, and the commencement of the payment of Base Rent and Additional Rent shall be delayed until such date, and for each day of delay after such 30 day period following the Substantial Completion Date until the date the Base Condition Default is cured, the Tenant shall be entitled to a credit of one additional day of Base Rent and Additional Rent. (b) If such Base Condition Default is not cured on or before ninety (90) days following the Substantial Completion Date the Tenant may, at its option, elect to either (i) if Landlord reasonably determines that Landlord's Construction will be substantially complete within 30 days following the end of such 90 day period, continue the remedy set forth in 3.02 (a) above where the Commencement Date and the commencement of the payment of Base Rent and Additional Rent shall be delayed, and for each day of delay after such 30 day period following the Substantial Completion Date until the date the Base Condition Default is cured, the Tenant shall be entitled to a credit of one additional day of Base Rent and Additional Rent; or (ii) cancel this Lease upon written notice to the Landlord within 30 days following the end of such 90 day period. Section 3.03. The Net Rentable Area of the Premises and the Building are approximately as stated in Sections 1.01, I and J, respectively. By written instrument substantially in the form of Exhibit D attached hereto, Landlord shall notify Tenant of the Substantial Completion Date, Commencement Date, the Net Rentable Area of the Premises and all other matters stated therein. The Commencement Notice shall be conclusive and binding on Tenant as to all matters set forth therein, unless within five (5) days following delivery of such Commencement Notice, Tenant contests any of the matters contained therein by notifying Landlord in writing of Tenant's objections. The foregoing notwithstanding, Landlord's failure to deliver any Commencement Notice to Tenant shall not affect Landlord's determination of the Commencement Date. Section 3.04. Tenant may not enter or occupy the Premises prior to the date Landlord delivers the Premises in Tenant Finish Ready Condition without Landlord's express written consent and any entry by Tenant shall be subject to all of the terms of this Lease; provided however, that no such early entry shall change the Commencement Date or the Expiration Date. It is the intent of the parties that Tenant shall have reasonable access to the Premises prior to the date Landlord delivers the Premises in Tenant Finish Ready Condition, so long as such access does not interfere with the actions of Landlord. Section 3.05. Except as set forth in a "punch list" or other document identifying exceptions presented to Landlord within thirty (30) days of occupancy, occupancy of the Premises or any portion thereof by Tenant or anyone claiming through or under Tenant for the conduct of Tenant's, or such other person's business therein shall be conclusive evidence that Tenant and all parties claiming through or under Tenant (a) have accepted the Premises as suitable for the purposes for which the Premises are leased hereunder, (b) have accepted the Common Areas as being in a good and satisfactory condition and (c) have waived any defects in the Premises and the Project. Landlord shall have no liability, except for gross negligence or willful misconduct, to Tenant or any of Tenant's agents, employees, licensees, servants or invitees for any injury or damage to any person or property due to the condition or design of, or any defect in, the Premises or the Project, including any electrical, plumbing or mechanical systems and equipment of the Premises or the Project and the condition of or any defect in the Land; and Tenant, for itself and its agents, employees, licensees, servants and invitees, expressly assumes all risks of injury or damage to person or property, either proximate or remote, resulting from the condition of the Premises or the Project. ARTICLE 4 RENT Section 4.01. Tenant shall pay to Landlord, without notice, demand, offset or deduction, in lawful money of the United States of America, at Landlord's Address for Payment, or at such other place as Landlord shall designate in writing from time to time: (a) the Base Rent in equal monthly installments, in advance, on the first day of each calendar month during the Term, and (b) the Additional Rent, at the respective times required hereunder. The first monthly installment of Base Rent and Tenant's Operating Costs Payment payable under Article 5 hereof shall be paid in advance on the date of Tenant's execution of this Lease and applied to the first installments of Base Rent and Tenant's Operating Costs Payment coming due under this Lease. Landlord shall place such first monthly installment in a federally insured, interest bearing account to be held until the Commencement Date whereupon the accrued interest on such first monthly installment shall be paid to Tenant and the first monthly installment shall be applied to Base Rent and Tenant's Operating Costs Payment as set forth above. Payment of Rent shall begin on the Commencement Date; provided, however, that, if either the Commencement Date or the Expiration Date falls on a date other than the first day of a calendar month, the Rent due for such fractional month shall be prorated on a per diem basis between Landlord and Tenant so as to charge Tenant only for the portion of such fractional month falling within the Term. Section 4.02. All past due installments of Rent shall bear interest until paid at a rate per annum (the "Interest Rate") equal to the greater of fifteen percent (15%) or four percent (4%) above the prime rate of interest from time to time publicly announced by Bank One, Texas, N.A., or any successor thereof; not to exceed the maximum rate permitted under federal law or under the laws of the State of Texas, the rate of interest on such past due installments of Rent shall be the maximum rate of interest then permitted by applicable law. 4 ARTICLE 5 OPERATING COSTS Section 5.01. Tenant shall pay to Landlord, as Additional Rent, for each year or fractional year during the Term an amount ("Tenant's Operating Costs Payment") of money equal to Tenant's Share of Operating Costs, as hereinafter defined, for such year, such amount to be calculated and paid as follows: (a) On the first day of January of each year during the Term (or, with respect to the year in which the Commencement Date occurs, the amount shown in Section 1.01 S. above), or as soon thereafter as is practicable, Landlord shall furnish Tenant with a statement ("Landlord's Operating Costs Estimate") setting forth Landlord's reasonable estimate of Operating Costs for the forthcoming year (or the fractional year in which the Commencement Date occurs, as the case may be). On the first day of each calendar month during such year, Tenant shall pay to Landlord one-twelfth of Tenant's Operating Costs Payment as estimated on Landlord's Operating Costs Estimate. If for any reason Landlord has not provided Tenant with Landlord's Operating Costs Estimate on the first day of January of any year during the Term (or by the Commencement Date, as the case may be), then, (i) until the first day of the calendar month following the month in which Tenant is given Landlord's Estimate of Operating Costs, Tenant shall continue to pay to Landlord on the first day of each calendar month the monthly sum, if any, payable by Tenant under this Section 5.01 for the month of December of the preceding year, and (ii) promptly after Landlord's Operating Costs Estimate is furnished to Tenant or together therewith, Landlord shall give notice to Tenant stating whether the installments of Tenant's Operating Costs Payments previously made for such year were greater or less than the installments of Tenant's Operating Costs Payments to be made for such year in accordance with Landlord's Operating Costs Estimate, and (A) if there shall be a deficiency, Tenant shall pay the amount thereof to Landlord within seven (7) days after the giving of Landlord's Operating Costs Estimate, or (B) if there shall have been an overpayment, Landlord shall apply such overpayment as a credit against the next accruing installment(s) of Additional Rent due from Tenant under this Section 5.01 until fully credited to Tenant, and (C) on the first day of the first calendar month following the month in which Tenant is given Landlord's Estimate of Operating Costs and on the first day of each calendar month thereafter during the Term throughout the remainder of such year, Tenant shall pay to Landlord an amount equal to one-twelfth (1/12th) of Tenant's Operating Costs Payment. The foregoing notwithstanding, Landlord shall have the right from time to time during any year to notify Tenant in writing of any change in Landlord's Operating Costs Estimate, in which event such Tenant's Operating Costs Payment, as previously estimated, shall be adjusted to reflect the amount shown in such notice and shall be effective, and due from Tenant, on the first day of each month during the year for which notice is given commencing the second month following Landlord's giving of such notice. (b) On the first day of March of each year during the Term (beginning on the first day of March of the year following the year in which the Commencement Date occurs), or as soon thereafter as is practicable, Landlord shall furnish Tenant with a statement of the actual Operating Costs for the preceding year. Within thirty (30) days after Landlord's delivery of such statement, Tenant shall make a lump sum payment to Landlord in the amount, if any, by which Tenants' Operating Costs Payment for such preceding year as shown on such Landlord's statement, exceeds the aggregate of the monthly installments of Tenant's Operating Costs Payments paid during such preceding year. If Tenant's Operating Costs Payment, as shown on such Landlord's statement, is less than the aggregate of the monthly installments of Tenant's Operating Costs Payment actually paid by Tenant during such preceding year, then Landlord shall apply such amount to the next accruing installment(s) of Additional Rent due from Tenant under this Section 5.01 until fully credited to Tenant. (c) If the Commencement Date occurs on a date other than the first day of January, or if the Term ends on a date other than the last day of December, the actual Operating Costs for the year in which the Commencement Date or the Expiration Date occurs, as the case may be, shall be prorated so that Tenant shall pay that portion of Tenant's Share of Operating Costs for such year represented by a fraction, the numerator of which shall be the number of days during such fractional year falling within the Term, and the denominator of which is 365 (or 366, in the case of a leap year). The provisions of this Section 5.01 shall survive the Expiration Date or any sooner termination provided for in this Lease. Section 5.02. For purposes of this Lease, the term "Operating Costs" shall mean any and all expenses, costs and disbursements of every kind which Landlord pays, incurs or becomes obligated to pay in connection with the operation, management, repair and maintenance of all portions of the Project. All Operating Costs shall be determined according to generally accepted accounting principles which shall be consistently applied. Operating Costs include, but are not limited to, the following: (a) The portion of wages, salaries, and fees (including, but not limited to, all reasonable educational, travel and professional fees) of all personnel or entities (exclusive of Landlord's executive personnel) allocable to the Project for any personnel engaged in the operation, repair, maintenance, or security of the Project, including taxes, insurance, and benefits relating thereto and the costs of all supplies and materials (including work clothes and uniforms) used in the operation, repair, and maintenance or security of the Project. (b) Cost of performance by Landlord's personnel of, or of all service agreements for, maintenance, janitorial services, access control, alarm service, window cleaning, elevator maintenance and landscaping for the Project. The foregoing project shall include rental of personal property used by Landlord's personnel in the maintenance and repair of the Project. 5 (c) All utilities for the Project, including water, sewer, power, electricity, gas, fuel, lighting and all other utilities; and all air-conditioning, heating and ventilating costs for the Project. (d) Cost of all insurance, including casualty and liability insurance applicable to the Project and to Landlord's equipment, fixtures and personal property used in connection therewith, business interruption or rent insurance against such perils as are commonly insured against by prudent landlords, such other insurance as may be required by any lessor or mortgagee of Landlord and such other insurance which Landlord considers reasonably necessary in the operation of the Project, together with all appraisal and consultants' fees in connection with such insurance. (e) All Taxes. For purposes hereof, the term "Taxes" shall mean (i) all taxes, assessments, and other governmental charges, applicable to or assessed against the Project or any portion thereof, or applicable to or assessed against Landlord's personal property used in connection therewith, whether federal, state, county, or municipal and whether assessed by taxing districts or authorities presently taxing the Project or the operation thereof or by other taxing authorities subsequently created, or otherwise, and any other taxes and assessments attributable to or assessed against all or any part of the Project or its operation, and (ii) any reasonable expenses, including fees and disbursements of attorneys, tax consultants, arbitrators, appraisers, experts and other witnesses, incurred by Landlord in contesting any taxes or the assessed valuation of all or any part of the Project. If at any time during the Term there shall be levied, assessed, or imposed on Landlord or all or any part of the Project by any governmental entity any general or special ad valorem or other charge or tax directly upon rents received under leases, or if any fee, tax, assessment, or other charge is imposed which is measured by or based, in whole or in part, upon such rents, or if any charge or tax is made based directly or indirectly upon the transactions represented by leases or the occupancy or use of the Project or any portion thereof, such taxes, fees, assessments or other charges shall be deemed to be Taxes; provided, however, that any (i) franchise, corporation, income or net profits tax, unless substituted for real estate taxes or imposed as additional charges in connection with the ownership of the Project, which may be assessed against Landlord or the Project or both, (ii) transfer taxes assessed against Landlord or the Project or both, (iii) penalties or interest on any late payments of Landlord, and (iv) personal property taxes of Tenant or other tenants in the Project shall be excluded from Taxes. If any or all of the Taxes paid hereunder are by law permitted to be paid in installments, notwithstanding how Landlord pays the same, then, for purposes of calculating Operating Costs, such Taxes shall be deemed to have been divided and paid in the maximum number of installments permitted by law, and there shall be included in Operating Costs for each year only such installments as are required by law to be paid within such year, together with interest thereon and on future such installments as provided by law. (f) Legal and accounting costs incurred by Landlord or paid by Landlord to third parties (exclusive of legal fees with respect to disputes with individual tenants, negotiations of tenant leases, or with respect to the ownership rather than the operation of the Project), appraisal fees, consulting fees, all other professional fees and disbursements and all association dues. (g) Cost of non-capitalized repairs and general maintenance of the Project (excluding repairs and general maintenance paid by proceeds of insurance or by Tenant, other tenants of the Project or other third parties). (h) Amortization of the cost of improvements or equipment which are capital in nature and which (i) are for the purpose of reducing Operating Costs of the Project, up to the amount saved as a result of the installation thereof, as reasonably estimated by Landlord, or (ii) enhance the Project for the general benefit of tenants or occupants thereof, or (iii) are required by any governmental authority, other than year 2000 compliance, and requirements necessary to comply with applicable law in effect at the execution date of this Lease, including without limitation the Americans with Disabilities Act of 1990, or (iv) replace any building equipment needed to operate the Project at the same quality levels as prior to the replacement. All such costs, including interest, shall be amortized on a straight-line basis over the useful life of the capital investment items, as reasonably determined by Landlord, but in no event beyond the reasonable useful life of the Project as a first class office project. (i) The portion of Project management office rent or rental value allocable to the Project. (j) A management fee (whether or not Landlord engages a manager for the Project) and all items reimbursable to the Project manager, if any, pursuant to any management contract for the Project. Landlord currently pays a management fee equal to three percent (3%) of the gross receipts from the Project and all items reimbursable to the Project manager pursuant to its management contract Landlord agrees that any future increase in the management fee payable by Landlord shall not exceed management fees customarily paid at the time by other landlords of first class office buildings in the Austin suburban area. (k) Amounts payable pursuant to the protective covenants, if any, as amended from time to time. "Operating Costs" shall not include (i) specific costs for any capital repairs, replacements or improvements, except as provided above; (ii) expenses for which Landlord is reimbursed or indemnified (either by an insurer, condemnor, tenant, warrantor or otherwise); (iii) expenses incurred in leasing or procuring tenants (including lease commissions, advertising expenses and expenses of renovating space for tenants); (iv) payments for rented equipment, the cost of which would constitute a capital expenditure not permitted pursuant to the foregoing if the equipment were purchased; (v) interest or amortization payments on any mortgages; (vi) net basic rents under ground leases; (vii) costs representing an amount paid to an affiliate of Landlord which is in excess of the amount which would have been paid in the absence of such relationship; (viii) wages, salaries or other compensation paid for clerks or attendants in concessions or news stands operated in the Project; (ix) the cost of installing, maintaining and operating any specialty service such as an observatory, broadcasting facility, luncheon club or an athletic or recreational club (except for 6 showers and locker areas); or (x) costs specially billed to or billable to any specific tenants. There shall be no duplication of costs or reimbursement. Landlord agrees to use commercially reasonable efforts to maintain the Operating Costs, the Taxes and the Landlord's insurance at the lowest possible level, using commercially reasonable efforts to reduce or eliminate Operating Costs, reduce Taxes and reduce insurance costs, and under all circumstances to maintain the Operating Costs, the Taxes and the insurance at no more than the substantially equivalent costs for other first class buildings in suburban Austin, Travis County, Texas. Notwithstanding anything contained in this Section 5.02 to the contrary or elsewhere in the Lease, for purposes of calculating Tenant's Operating Costs Payment for the period beginning on January 1, 2001, and for each year thereafter during the Term of this Lease, the components of Operating Costs set forth in Sections 5.02 (a), (b) (excluding janitorial services), (f), (g), (h), (i), and (j) (collectively the "Controllable Operating Costs") shall not be annually increased by more than six percent (6%) per annum over the actual 2000 "grossed up" Controllable Operating Costs. For purposes of this paragraph, the cap on the Controllable Operating Costs for years 2002 and thereafter shall be determined on a compounded and cumulative basis from 2001. Section 5.03. If the Building is not 95% occupied (meaning ninety-five percent (95%) of the Net Rentable Area of the Building) during any full or fractional year of the Term, the actual Operating Costs shall be adjusted for such year to an amount which Landlord estimates would have been incurred in Landlord's reasonable judgment had the Building been 95% occupied. Section 5.04.

In the event of partial destruction or damage to the Building or the Premises which is not subject to Section 15.01 or 15.02, but which renders the Premises partially but not wholly untenantable, this Lease shall not terminate and Rent shall be abated in proportion to the area of the Premises which, in Landlord's reasonable opinion, cannot be used or occupied by Tenant as a result of such casualty. Landlord shall in such event, within a reasonable time after the date of such destruction or damage, subject to tenant delay and to the extent and availability of insurance proceeds, restore the Premises to as near the same condition as existed prior to such partial damage or destruction. In no event shall Rent abate or shall any termination occur if damage to or destruction of the Premises is the result of the negligence or willful misconduct of Tenant, or Tenant's agents, employees, representatives, contractors or successors. Section 15.04. If the Building or the Premises or any portion greater than 20% thereof is destroyed by fire or other causes at any time during the last two years of the Term, then either Landlord or Tenant shall have the right, at the option of either party, to terminate this Lease by giving written notice to the other within sixty (60) days after the date of such destruction. Section 15.05. Landlord shall have no liability to Tenant for inconvenience, loss of business, or annoyance arising from any repair of any portion of the Premises or the Building. If Landlord is required by this Lease or by any mortgagee or lessor of Landlord to repair, or if Landlord undertakes to repair, Landlord shall use reasonable efforts to have such repairs made promptly and in a manner which will not unnecessarily interfere with Tenant's occupancy. Section 15.06. In the event of termination of this Lease pursuant to Sections 15.01, 15.02, or 15.04, then all Rent shall be apportioned and paid to the date on which possession is relinquished or the date of such damage, whichever last occurs, and Tenant shall immediately vacate the Premises according to such notice of termination; provided, however, that those provisions of this Lease which are designated to cover matters of termination and the period thereafter shall survive the termination hereof. ARTICLE 16 CONDEMNATION Section 16.01. In the event any portion of the Building, the Premises or the Project are taken or condemned by eminent domain or by any conveyance in lieu thereof (such taking, condemnation or conveyance in lieu thereof being hereinafter referred to as "condemnation"), which taking, in Landlord's judgment, is such that the Building or the Premises cannot be restored in an economically feasible manner for use substantially as originally designed, then either Landlord or Tenant shall have the right to terminate this Lease, by giving written notice of termination within sixty (60) days of notice of the proposed taking and Rent shall be apportioned as of the date of such termination. Section 16.02. In the event any portion of the Parking Facilities shall be taken by condemnation, which taking in Landlord's judgment is such that the Parking Facilities cannot be restored in an economically feasible 13 manner for use substantially as originally designed, including in such consideration the possible use of additional parking facilities in the vicinity of the Building, then Landlord shall have the right, at Landlord's option, to terminate this Lease, effective as of the date specified by Landlord in a written notice of termination from Landlord to Tenant. Section 16.03. In the event that a portion of the Premises shall be taken by condemnation, and this Lease is not terminated pursuant to Section 16.01, then this Lease shall be terminated as of the date of such condemnation as to the portion of the Premises so taken, and this Lease shall remain in full force and effect as to the remainder of the Premises. Section 16.04. All compensation awarded or paid upon a condemnation of any portion of the Project shall belong to and be the property of Landlord without participation by Tenant. Nothing herein shall be construed, however, to preclude Tenant from prosecuting any claim directly against the condemning authority for loss of business, loss of good will, moving expenses, damage to, and cost of removal of, trade fixtures, furniture and other personal property belonging to Tenant; provided, however, that Tenant shall make no claim which shall diminish or adversely affect any award claimed or received by Landlord. Section 16.05. If any portion of the Project other than the Building or the Parking Facilities is taken by condemnation, or if the temporary use or occupancy of all or any part of the Premises shall be taken by condemnation during the Term, this Lease shall be and remain unaffected by such condemnation, and Tenant shall continue to pay in full the Rent payable hereunder. ARTICLE 17 INDEMNIFICATION Section 17.01. Tenant shall and hereby agrees to, indemnify and hold Landlord harmless from any damages in connection with loss of life, bodily or personal injury, or property damages arising from an occurrence in the Premises, when not solely the result of the gross negligence or willful misconduct of Landlord, its agents, employees, representatives, contractors, licensees and invitees. Tenant and its agents, employees, representatives, contractors, licensees and invitees, hereby waive all claims against Landlord for damage to any property or injury to, or death of, any person in, upon, or about the Project, including the Premises, arising at any time and from any cause other than solely by reason of the gross negligence or willful misconduct of Landlord, its agents, employees, representatives, or contractors. Without limiting the generality of the foregoing, Landlord shall not be liable for any injury or damage to persons or property resulting from the condition or design of, or any defect in the Building or its mechanical systems or equipment which may exist or occur or from any fire, explosion, falling plaster, steam, gas, electricity, water, rain, flood, snow, or leaks from any part of the Premises or from the pipes, appliances, plumbing works, roof, or subsurface of any floor or ceiling, or from the street or any other place, or by dampness or by any other similar cause unless the same is caused solely by the gross negligence or willful misconduct of Landlord, its agents, employees, representatives or contractors. Landlord shall not be liable for any such damage caused by other tenants or persons in the Building or by occupants of adjacent property thereto, or by the public, or caused by construction (unless caused solely by the gross negligence or willful misconduct of Landlord) or by any private, public or quasi-public work. The provisions of this Article 17 shall survive the expiration or termination of this Lease with respect to any damage, injury, or death occurring before such expiration or termination. Section 17.02. Landlord shall, and hereby agrees to, indemnify and hold Tenant harmless from any damages in connection with loss of life, bodily or personal injury or property damage arising from any occurrence in the Common Areas of the Project when not solely the result of the gross negligence or willful misconduct of Tenant, and its agents, employees, representatives, contractors, licensees, and invitees. ARTICLE 18 SUBORDINATION AND ESTOPPEL CERTIFICATES Section 18.01. This Lease and all rights of Tenant hereunder are subject and subordinate to all underlying leases now or hereafter in existence, and to any supplements, amendments, modifications, and extensions of such leases heretofore or hereafter made and to any deeds to secure debt, mortgages, or other security instruments which now or hereafter cover all or any portion of the Project or any interest of Landlord therein, and to any advances made on the security thereof, and to any increases, renewals, modifications, consolidations, replacements, and extensions of any of such mortgages. This provision is declared by Landlord and Tenant to be self-operative and no further instrument shall be required to effect such subordination of this Lease. Upon demand, Tenant shall execute, acknowledge, and deliver to Landlord any further instruments and certificates evidencing such subordination as Landlord, and any mortgagee or lessor of Landlord shall reasonably require. Tenant shall not unreasonably withhold, delay, or defer its written consent reasonable modifications in this Lease which are a condition of any financing for the Project or any reciprocal easement agreement with facilities in the vicinity of the Building, provided that such modifications do not increase the obligations of Tenant hereunder or materially and adversely affect Tenant's use and enjoyment of the Premises. Section 18.02. Notwithstanding the generality of the foregoing provisions of Section 18.01, any mortgagee or lessor of Landlord shall have the right at any time to subordinate any such mortgage or underlying lease to this Lease, or to any of the provisions hereof, on such terms and subject to such conditions as such mortgagee or lessor of Landlord may consider appropriate in its discretion. At any time, before or after the institution of any proceedings for the foreclosure of any such mortgage, or the sale of the Building under any such mortgage, or the termination of any 14 underlying lease, Tenant shall, upon request of such mortgagee or any person or entities succeeding to the interest of such mortgagee or the purchaser at any foreclosure sale ("Successor Landlord"), automatically become the Tenant (or if the Premises has been validly subleased, the subtenant) of the Successor Landlord, without change in the terms or other provisions of this Lease (or, in the case of a permitted sublease, without change in this Lease or in the instrument setting forth the terms of such sublease); provided, however, that the Successor Landlord, if Tenant shall have had prior written notice of the mortgage of the Project, shall not be (i) bound by any payment made by Tenant of Rent or Additional Rent for more than one (1) month in advance, except for a Security Deposit previously paid to Landlord, (ii) bound by any termination, modification, amendment or surrender of the Lease done without the Successor Landlord's consent after Tenant has been notified of the Successor Landlord's interest in the Project, (iii) liable for any damages or subject to any offset or defense by Tenant to the payment of Rent by reason of any act or omission of any prior landlord (including Landlord), unless written notice thereof shall have been provided to Successor Landlord, or (iv) personally or corporately liable, in any event, beyond the limitations on landlord liability set forth in Section 25.05 of this Lease. This agreement of Tenant to attorn to a Successor Landlord shall survive any such foreclosure sale, trustee's sale conveyance in lieu thereof or termination of any underlying lease. Tenant shall upon demand at any time, before or after any such foreclosure or termination execute, acknowledge, and deliver to the Successor Landlord any written instruments and certificates evidencing such attornment as such Successor Landlord may reasonably require. Section 18.03. Tenant shall, from time to time, within ten (10) days after request from Landlord, or from any mortgagee or lessor of Landlord, execute, acknowledge and deliver in recordable form a certificate certifying, to the extent true, that this Lease, as the Lease may have been amended, is in full force and effect; that the Term has commenced and the full amount of the Rent then accruing hereunder; the dates to which the Rent has been paid; that Tenant has accepted possession of the Premises and that any improvements required by the terms of this Lease to be made by Landlord have been completed to the satisfaction of Tenant; the amount, if any, that Tenant has paid to Landlord as a Security Deposit; that no Rent under this Lease has been paid more than thirty (30) days in advance of its due date; that the address for notices to be sent to Tenant is as set forth in this Lease, or has been changed as set forth in the certificate; that Tenant has no charge, lien, or claim of offset under this Lease or otherwise against Rent or other charges due or to become due hereunder; that, to the knowledge of Tenant, Landlord is not then in default under this Lease; and such other matters as may be reasonably requested by Landlord or any mortgagee or lessor of Landlord. Any such certificate may be relied upon by Landlord, any Successor Landlord, or any mortgagee or lessor of Landlord. Landlord agrees periodically to furnish, when reasonably requested in writing by Tenant, certificates signed by Landlord containing information similar to the foregoing information. Section 18.04. No act or failure to act on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, to be relieved of Tenant's obligations hereunder or to terminate this Lease, shall result in a release of such obligations or a termination of this Lease unless (a) Tenant has given notice by registered or certified mail to any mortgagee or lessor of Landlord whose address shall have been furnished to Tenant, and (b) Tenant offers such mortgagee or lessor of Landlord a reasonable opportunity to cure the default, including time to obtain possession of the Premises by power of sale or judicial foreclosure, if such should prove necessary to effect a cure. ARTICLE 19 SURRENDER OF THE PREMISES Section 19.01. By no later than 11:59 p.m. of the Expiration Date or the date of earlier termination of this Lease, or upon any re-entry of the Premises by Landlord without terminating this Lease pursuant to Section 13.02(b), Tenant, at Tenant's sole cost and expense, shall peacefully vacate and surrender the Premises to Landlord in good order, broom clean and in the same condition as at the beginning of the Term or as the Premises may thereafter have been improved, reasonable use and wear thereof and repairs which are Landlord's obligations under Articles 9, 15 and 16 only excepted, and Tenant shall remove all of Tenant's Property and turn over all keys for the Premises to Landlord. Section 19.02. Should Tenant continue to hold the Premises after the expiration or earlier termination of this Lease, such holding over, unless otherwise agreed to by Landlord in writing, shall constitute and be construed as a tenancy at sufferance at monthly installments of Rent equal to one hundred fifty percent (150%) of the monthly portion of Base Rent in effect as of the date of expiration or earlier termination, plus Tenant's Operating Costs Payment, and subject to all of the other terms, charges and expenses set forth herein except any right to renew this Lease or to expand the Premises or any right to additional services. The provisions of this Article 19 shall survive the expiration or earlier termination of this Lease. Notwithstanding anything to the contrary, in the event Landlord and Tenant are involved in negotiations for an extension at the expiration of the second renewal term set forth in Article 28 below, the holdover rent shall not go into effect until the earlier of (i) the termination of such negotiations, other than upon execution of a lease or renewal, or (ii) the expiration of thirty (30) days. ARTICLE 20 LANDLORD'S RIGHT TO INSPECT Section 20.01. Landlord shall retain duplicate keys to all doors of the Premises. Tenant shall provide Landlord with new keys should Tenant receive Landlord's consent to change the locks. Landlord shall have the right to enter the Premises at reasonable hours upon reasonable notice (or, in the event of an emergency, at any hour); provided, however, Landlord shall use reasonable efforts to minimize interference with Tenant's business. Landlord shall not be liable to Tenant for the exercise of Landlord's rights under this Article 20 and Tenant hereby waives any 15 claims for damages for any injury, inconvenience or interference with Tenant's business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. ARTICLE 21 SECURITY DEPOSIT Section 21.01 A. On the date Landlord delivers the Premises to Tenant in Tenant Finish Ready Condition, Tenant shall deposit $1,850,000.00 in cash (the "Security Deposit") to be held in escrow by Frost National Bank or other bank selected by Tenant and satisfactory to Landlord, which shall not be unreasonably withheld (the "Escrow Agent"). Prior to the occurrence of a monetary Event of Default or, if applicable, the date Tenant has net working capital below the Working Capital Minimum (as defined below) determined as provided below, interest may be periodically distributed to Tenant. After the occurrence of a monetary Event of Default or Tenant's falling below the Working Capital Minimum, if applicable, all undistributed accrued interest shall become part of the Security Deposit. Tenant shall not assign or in any way encumber the Security Deposit. B. Upon the occurrence of any monetary Event of Default by Tenant, Landlord shall have the right, without prejudice to any other remedy, to submit a sworn affidavit executed by Landlord stating that Tenant is in default under the Lease and that the cure period for such default has expired (specifically setting forth the Event of Default) and the monetary amount necessary to cure such default. A copy of such notice shall be sent to Tenant. Unless within five (5) Business Days from such notice, Tenant shall have filed suit to enjoin such payment and served a copy thereof on Landlord and Escrow Agent, Escrow Agent shall on the sixth (6th ) Business Day pay to Landlord out of the Security Deposit the amount set forth in the notice from Landlord without any approval needed from Tenant. If the entire Security Deposit is paid to Landlord as set forth in this Section, Landlord shall be entitled to the undistributed accrued interest on the Security Deposit to the extent necessary to cure monetary Events of Default. C. If there have been no monetary Events of Default by Tenant as of the first anniversary of the Commencement Date, the Security Deposit shall be reduced to $1,100,000.00 and the Escrow Agent shall return $750,000.00 to Tenant. If there have been no monetary Events of Default by Tenant as of the second (2nd) anniversary of the Commencement Date (the "Security Deposit Termination Date"), the Security Deposit and all undistributed accrued interest thereon shall be returned to Tenant. Provided, however, if during such two year period there is a monetary Event of Default by Tenant, the Security Deposit Termination Date shall be extended until Tenant has not had a monetary Event of Default for at least two consecutive years and notwithstanding anything contained in this paragraph to the contrary, Escrow Agent shall hold the Security Deposit (in the amount then held by Escrow Agent) until the Security Deposit Termination Date. Provided, further, in the event that Billing Concepts Corp., a Delaware corporation has been released (the "Guaranty Release Date") from its obligations to unconditionally guarantee Tenant's performance under this Lease as set forth in that certain Guaranty executed by Billing Concepts Corp. contemporaneously with this Lease, if at any time prior to the Security Deposit Termination Date, Tenant has net working capital of less than $30,000,000.00 ("Working Capital Minimum"), the Security Deposit shall be held by Escrow Agent until Tenant has had net working capital in excess of the Working Capital Minimum for two consecutive fiscal quarters of Tenant. For the purposes hereof, "net working capital" shall be defined as current assets (consisting of cash and accounts receivable) minus current liabilities (including without limitation accounts payable and the current portion of long term debt) all determined pursuant to generally accepted accounting principles, consistently applied. Following the Guaranty Release Date, but prior to the Security Deposit Termination Date, and thereafter if the same shall be extended, Tenant shall quarterly submit to Landlord a statement of Net Working Capital certified to be correct by Tenant's outside certified public accountants; such statement to be delivered to Landlord within 60 days of the end of each of Tenant's fiscal quarters. If Landlord receives from Tenant a statement indicating that Tenant is below the Working Capital Minimum, Landlord will promptly forward a copy of such financial report to Escrow Agent. On the Security Deposit Termination Date, the Security Deposit shall be released and delivered to Tenant upon submission by Tenant to Escrow Agent of a sworn affidavit stating that all conditions to the release the Security Deposit have been satisfied. A copy of such notice shall be sent to Landlord. Unless within five (5) Business Days following such notice from Tenant, Landlord shall have filed suit to enjoin the release of the Security Deposit and served a copy thereof on Escrow Agent or Tenant, Escrow Agent shall on the sixth (6th) Business Day following such notice from Tenant release the Security Deposit to Tenant, without any approval needed from Landlord. ARTICLE 22 BROKERAGE Section 22.01. Landlord shall pay to Tenant's exclusive broker, Mark A. Vickery, Mark A. Vickery Interests, Inc., a commission pursuant to a separate written agreement. Tenant and Landlord each represent and warrant to the other that it has not entered into any agreement with, or otherwise had any dealings with, any broker or agent in connection with the negotiation or execution of this Lease which could form the basis of any claim by any such broker or agent for a brokerage fee or commission, finder's fee, or any other compensation of any kind or nature in connection herewith, other than with Broker, and each party shall, and hereby agrees to, indemnify and hold the other harmless from all costs (including court costs, investigation costs, and attorneys' fees), expenses, or liability for commissions or other compensation claimed by any broker or agent with respect to this Lease which arise out of any agreement or dealings, or alleged agreement or dealings, between the indemnifying party and any such agent or broker, other than with Broker. This provision shall survive the expiration or earlier termination of this Lease. 16 ARTICLE 23 OBSERVANCE OF RULES AND REGULATIONS Section 23.01. Tenant and Tenant's servants, employees, agents, visitors, and licensees shall observe faithfully and comply strictly with all Rules and Regulations (herein so called) attached to this Lease as such Rules and Regulations may be changed from time to time. Landlord shall at all times have the right to make reasonable changes in and additions to such Rules and Regulations; provided Landlord gives Tenant prior notice of such changes and provided that such new rules and regulations or changes in existing rules and regulations do not conflict with this Lease, and do not materially interfere with the lawful conduct of Tenant's business in the Premises. Landlord shall not be liable to Tenant for the failure or refusal by any other tenant, guest, invitee, visitor, or occupant of the Building to comply with any of the Rules and Regulations. ARTICLE 24 NOTICES Section 24.01. All notices, consents, demands, requests, documents, or other communications (other than payment of Rent) required or permitted hereunder (collectively, "notices") shall be deemed given, whether actually received or not, when dispatched for hand delivery or delivery by air express courier (with signed receipts) to the other party, or on the second Business Day after deposit in the United States mail, postage prepaid, certified, return receipt requested, except for notice of change of address which shall be deemed given only upon actual receipt, or on the same Business Day if sent by telecopier prior to 5:00 p.m., local Austin, Texas time, and the sending telecopier generates a written confirmation of sending and the providing party follows up with a hard copy of such notice being sent the same Business Day via another approved method for notice as provided in this Section 24.01. The addresses of the parties for notices are set forth in Article 1, or any such other addresses subsequently specified by each party in notices given pursuant to this Section 24.01. ARTICLE 25 MISCELLANEOUS Section 25.01. PROFESSIONAL FEES.

Section 25.02. REIMBURSEMENTS. Wherever the Lease requires Tenant to reimburse Landlord for the cost of any item, such costs will be the reasonable and customary charge periodically established by Landlord for such item, including a fee for Landlord's manager's supervision in connection with providing such item. Section 25.03. SEVERABILITY. Every agreement contained in this Lease is, and shall be construed as, a separate and independent agreement.

Section 25.04. NON-MERGER. There shall be no merger of this Lease with any ground leasehold interest or the fee estate in the Project or any part thereof by reason of the fact that the same person may acquire or hold, directly or indirectly, this Lease or any interest in this Lease as well as any ground leasehold interest or fee estate in the Project or any interest in such fee estate. Section 25.05. LANDLORD'S LIABILITY. Anything contained in this Lease to the contrary notwithstanding, Tenant agrees that Tenant shall look solely to the estate and property of Landlord in the Project for the collection of any judgment or other judicial process requiring the payment of money by Landlord for any default or breach by Landlord under this Lease, subject, however, to the prior rights of any mortgagee or lessor of the Project. No other assets of Landlord or any partners, shareholders, or other principals of Landlord shall be subject to levy, execution or other judicial process for the satisfaction of Tenant's claim. Section 25.06. FORCE MAJEURE. Whenever the period of time is herein prescribed for action to be taken by Landlord or Tenant, Landlord or Tenant shall not be liable or responsible for, and there shall be excluded from the computation for any such period of time, any delays due to force majeure, which term shall include strikes, riots, acts of God, shortages of labor or materials, war, governmental approvals, laws, regulations, or restrictions, or any other cause of any kind whatsoever which is beyond the reasonable control of Landlord or Tenant. Force Majeure shall not excuse or delay Tenant's obligation to Rent or any other amount due under this Lease. Section 25.07. HEADINGS.

Should any provision of this Lease require judicial interpretation, Landlord and Tenant hereby agree and stipulate that the court interpreting or considering same shall not apply the presumption that the terms hereof shall be more strictly construed against a party by reason of any rule or conclusion that a document should be construed more strictly against the party who itself or through its agents prepared the same, it being agreed that all parties hereto have participated in the preparation of this Lease and that each party had full opportunity to consult legal counsel of its choice before the execution of this Lease. Section 25.13. TENANT'S USE OF NAME OF THE BUILDING.

Section 25.14. ANCIENT LIGHTS. Any elimination or shutting off of light, air, or view by any structure which may be erected on lands adjacent to the Building shall in no way affect this Lease and Landlord shall have no liability to Tenant with respect thereto.

Landlord shall also have the right to (a) rearrange, change, expand or contract portions of the Project constituting Common Areas (b) to use Common Areas while engaged in making improvements, repairs or alterations to the Project, or any portion thereof, and (c) to do and perform such other acts and make such other changes in to or with respect to the Project, or any portion thereof, as Landlord may, in the exercise of sound business judgment, deem to be appropriate. Landlord shall be entitled to change the name or address of the Building or the Project. Landlord shall have the right to close, from time to time, the Common Areas and other portions of the Project for such temporary periods as Landlord deems legally sufficient to evidence Landlord's ownership and control thereof and to prevent any claim of adverse possession by, or any implied or actual dedication to, the public or any party other than Landlord.
