DEFINITIONS. The definitions of certain of the capitalized terms used in this Lease are set forth in the Glossary of Defined Terms attached as Exhibit A. 2. PREMISES. Subject to the provisions of this Lease, Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, approximately 2,994 rentable square feet of space in the Building known as THE MADISON, which space is outlined on the floor plan attached hereto as Exhibit B (the "PREMISES"). In connection with such demise, Landlord hereby grants to Tenant the non-exclusive right to use during the Term all Common Areas designed for the use of all tenants in the Building, in common with all tenants in the Building and their invitees, for the purposes for which designed and in accordance with all Legal Requirements. By occupying the Premises, Tenant accepts the Premises as being suitable for Tenant's intended use of the Premises. 3. TERM. The Term of this Lease shall commence on the Commencement Date (which is scheduled to be May 1, 2002) and shall expire at 5:00 p.m. October 31, 2005 unless earlier terminated as provided herein (the "TERM"). 4. USE. Tenant shall occupy and use the Premises solely for lawful, general business office purposes in strict compliance with the Building Rules and Regulations from time to time in effect and all other Legal Requirements. 5. RENT. 5.1 BASE RENT. In consideration of Landlord's leasing the Premises to Tenant, Tenant shall pay to Landlord as follows: Monthly Term Amount ---- ------ May 1, 2002 - June 30, 2002 Waived July 1, 2002 - October 31, 2002 $3,742.50 / month November 1, 2002 - October 31, 2003 $4,740.50 / month November 1, 2003 - October 31, 2004 $5,114.75 / month November 1, 2004 - October 31, 2005 $5,364.25 / month The Base Rent set forth in this Section 5.1 is a negotiated figure and shall govern whether or not the actual gross rentable square footage of the Premises is the same as set forth in Section 2 hereof or changes pursuant to the standards set in the definition of Net Rentable Area. Tenant shall have no right to withhold, deduct or offset any amount of the monthly Base Rent or any other sum due hereunder even if the actual gross rentable square footage of the Premises is less than that set forth in Section 2 hereof or changes pursuant to the standards set forth in the definition of Net Rentable Area. [5.2 Deleted] 5.3 ADDITIONAL RENT. For purposes of this Lease, Tenant's "ADDITIONAL RENT" for any Fiscal Year (or portion thereof) shall mean the sum of (a) Tenant's Prorata Share of Operating Expenses plus (b) Tenant's Prorata Share of Impositions. For purposes of this Lease, Tenant's Prorata Share of Operating Expenses shall mean and be equal to the product of (x) Net Rentable Area of the Premises multiplied by (y) the difference, if positive, between (i) the amount of Operating Expenses divided by the Net Rentable Area of the Building minus (ii) the Expense Stop, all as applicable for the period in question. For purposes of this Lease, Tenant's Prorata Share of Impositions shall mean and be equal to the product of (x) Net Rentable Area of the Premises multiplied by (y) the difference, if positive, between (i) the amount of Impositions divided by the Net Rentable Area of the Building minus (ii) the Impositions Stop, all as applicable for the period in question. By the Commencement Date, Landlord shall estimate the Additional Rent to be due by Tenant for the balance of the Fiscal Year in which the Commencement Date occurs. Thereafter, unless Landlord delivers to Tenant a revision of the estimated Additional Rent, Tenant shall pay to Landlord, coincident with Tenant's payment of Base Rent, an amount equal to the estimated Additional Rent for the remainder of such year divided by the number of months remaining in such year. From time to time during any Fiscal Year, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant for that Fiscal Year and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimation so that, by the end of the Fiscal Year, Tenant shall have paid all of the Additional Rent as estimated by Landlord. After the conclusion of each Fiscal Year during the Term, and after the termination or expiration of the Term, Landlord shall deliver to Tenant a statement of actual Additional Rent due by Tenant for the Fiscal Year (or, with respect to termination or expiration, the portion of the Fiscal Year) just ended. Within 30 days thereafter, Tenant shall pay to Landlord or Landlord shall credit against the next installment of Additional Rent due by Tenant (or Landlord shall refund to Tenant, if the Term has expired and all payments due by Tenant to Landlord have been paid in full) the difference between the actual Additional Rent due for such year and the estimated Additional Rent paid by Tenant during such year. Tenant may review, at Tenant's expense and after giving 20-days' prior written notice to Landlord, Landlord's records relating to Operating Expenses and Impositions for any periods within two Fiscal Years prior to the review; provided, however, no review shall extend to periods of time preceding the Commencement Date. In lieu of allowing Tenant to review Landlord's records under this Section 5.3, Landlord may deliver to Tenant a report of the Operating Expenses and Impositions prepared by a certified public accountant, which report shall be conclusive for purposes of this Lease. 5.4 PARKING CHARGE. Tenant shall at all times during the Tern lease from Landlord twelve (12) unassigned automobile parking spaces in the Parking Facility at no extra charge. TENANT MAY ALSO LEASE FOUR (4) RESERVED PARKING SPACES FOR A MONTHLY FEE OF $25.00 PER SPACE FOR MONTHS 1 - 12, $50.00 PER SPACE FOR MONTHS 13 - 24 AND $75.00 PER SPACE FOR MONTHS 25 - 42. 5.5 PAYMENT OF RENT. Except as otherwise expressly provided in this Lease, all Rent shall be due in advance monthly installments on the first day of each calendar month during the Tenn. Rent shall be paid to Landlord at its address recited in Section 27.7 or to such other person or at such other address as Landlord may from time to time designate in writing. Rent shall be paid without notice, demand, abatement, deduction or offset in legal tender of the United States of America. If the Term commences or ends on other than the first or the last day of a calendar month, the Rent for the partial month shall be prorated on the basis of the number of days during the month for which the Term was in effect. If the Term commences or ends on other than the first or the last day of a Fiscal Year, the Additional Rent for the partial Fiscal Year shall be prorated on the basis of the number of days during the Fiscal Year for which the Term was in effect. 5.6 DELINQUENT PAYMENTS AND HANDLING CHARGE. All Rent and other payments required of Tenant hereunder shall bear interest from the date due until the date paid at the rate of interest specified in Section 27.13. Alternatively, Landlord may charge Tenant, as additional Rent hereunder, a fee equal to five percent of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a consequence of Tenant's delinquency. In no event, however, shall the charges permitted under this Section 5.6 or elsewhere in this Lease, to the extent the same are considered to be interest under applicable law, exceed the maximum rate of interest allowable under applicable law. 5.7 PREPAID RENT AND SECURITY DEPOSIT. Landlord hereby acknowledges receipt of $5,114.75 representing (a) the Security Deposit as security for the full and timely payment and performance by Tenant of its obligations under this Lease. Landlord may apply any or all of the Security Deposit toward the payment of any sum or the performance of any obligation which Tenant was obligated, but failed, to pay or perform hereunder. The Security Deposit shall not be considered an advance payment of Rent by Tenant or a measure of or a limit to Landlord's damages upon an Event of Default. TENANT SHALL PAY TO LANDLORD A DEPOSIT OF $20.00 FOR EACH ACCESS CARD REQUESTED TO GAIN ACCESS TO THE BUILDING. 6. CONSTRUCTION OF IMPROVEMENTS. 6.1 GENERAL. Subject to events of Force Majeure, Landlord shall install, furnish, perform and apply, at its expense, the Landlord's Work as specified in the Work Letter. Performance of the Landlord's Work shall constitute Landlord's sole construction obligation to Tenant under this Lease. 6.2 ACCESS BY TENANT PRIOR TO COMMENCEMENT OF TERM. Provided that Tenant obtains and delivers to Landlord the certificates or policies of insurance called for in Section 17.1, Landlord, in its sole discretion, may permit Tenant and its employees, agents, contractors and suppliers to enter the Premises before the Commencement Date (and such entry, alone, shall not constitute Tenant's taking possession of the Premises for the purpose of Section 6.3(c)) to prepare the Premises for Tenant's occupancy. Tenant and each other person or firm who or which enters the Premises before the Commencement Date shall conduct itself so as to not interfere with Landlord or other occupants of the Building. Landlord may withdraw any permission granted under this Section 6.2 upon 24-hours' notice to Tenant if Landlord, in its sole discretion, determines that any such interference has been or may be caused. Any prior entry shall be under all of the terms of this Lease (other than the obligation to pay Base Rent and Additional Rent) and at Tenant's sole risk. Landlord shall not be liable in any way for personal injury, death or property damage (including damage to any personal property which Tenant may bring into, or any work which Tenant may perform in, the Premises) which may occur in or about the Complex by Tenant or such other person or firm as a result of any prior entry. 6.3 COMMENCEMENT DATE: ADJUSTMENTS TO COMMENCEMENT DATE. For purposes of this Lease, the "COMMENCEMENT Date" shall mean the earliest of: (a) the date on which Landlord substantially completes the Landlord's Work and tenders possession of the Premises to Tenant; or (b) the date on which Landlord would have substantially completed the Landlord's Work and tendered possession of the Premises to Tenant but for (i) the delay or failure of Tenant to furnish information or other matters required in the Work Letter, (ii) Tenant's request for changes in the Plans or non-Building Standard Items or (iii) any other action or inaction of Tenant, or any person or firm employed or retained by Tenant or the date on which Tenant takes possession of the Premises. If by the scheduled Commencement Date specified in Section 3 the Landlord's Work has not been substantially completed, and such failure to substantially complete renders the Premises untenable for their intended purpose, all as reasonably determined by Landlord, or Landlord is unable to tender possession of the Premises to Tenant, then the Commencement Date (and the commencement of payment of Base Rent and Additional Rent) shall be postponed until the Landlord's Work is substantially completed as reasonably determined by Landlord or until possession of the Premises is tendered to Tenant, as the case may be. Such postponement shall extend the scheduled expiration of the Term for a number of days equal to the postponement. The postponement of the payment of Base Rent and Additional Rent under this Section 6.3 shall be Tenant's exclusive remedy for Landlord's delay in completing the Landlord's Work or tendering possession of the Premises to Tenant. 7. SERVICES TO BE FURNISHED BY LANDLORD. 7.1 GENERAL. Subject to applicable Legal Requirements and Tenant's performance of its obligations hereunder, Landlord shall use all reasonable efforts to furnish the following services: (a) Air-conditioning and heating to the Premises during Building Operating Hours, at such temperatures and in such amounts as are considered by Landlord to be suitable and standard (thus excluding air-conditioning or heating for electronic data processing or other specialized equipment); (b) Hot and cold water at those points of supply common to all floors for lavatory and drinking purposes only; (c) Janitor service and periodic window washing in and about the Building and the Premises; (d) Elevator service, if necessary, to provide access to and egress from the Premises; (e) Electric current during Building Operating Hours for normal office machines and other machines of low electrical consumption (which shall exclude electric current for electronic data processing equipment, lighting in excess of Building Standard or any other item of electrical equipment which singly consumes more than 0.5 kilowatts per hour at rated capacity or requires a voltage other than 120 volts single phase); and (f) Replacement of fluorescent lamps in Building Standard light fixtures installed by Landlord and of incandescent bulbs or fluorescent lamps in all public restrooms, stairwells and other common areas in the Building. If any of the services described above or elsewhere in this Lease are interrupted, Landlord shall use reasonable diligence to promptly restore same. However, neither the interruption or cessation of such services nor the failure of Landlord to restore same shall render Landlord liable for damages to person or property, or be construed as an eviction of Tenant, or work an abatement of Rent or relieve Tenant from fulfilling any of its other obligations hereunder. 7.2 KEYS. Landlord shall furnish Tenant, at Landlord's expense, with (four 4) keys, and at Tenant's expense with such additional keys as Tenant may request, to unlock each corridor door entering the Premises. Tenant shall not install, or permit to be installed, any additional lock on any door into or in the Premises or make, or permit to be made, any duplicates of keys to the Premises. Landlord shall be entitled at all times to possession of a duplicate of all keys to all doors to or inside of the Premises. All keys referred to in this Section 7.2 shall remain the property of Landlord. Upon the expiration or termination of the Term, Tenant shall surrender all such keys to Landlord and shall deliver to Landlord the combination to all locks on all safes, cabinets and vaults which will remain in the Premises. Landlord shall be entitled to install, operate and maintain security systems in or about the Premises and the Complex which monitor, by closed circuit television or otherwise, all persons leaving or entering the Complex, the Building and the Premises. 7.3 TENANT IDENTITY. Landlord shall provide and install, in Building Standard graphics, letters or numerals identifying Tenant's name and suite number on entrance doors to the Premises. Without Landlord's prior written consent, no other signs, numerals, letters, graphics, symbols or marks identifying Tenant shall be placed on the exterior, or on the interior if they are visible from the exterior, of the Premises. Landlord shall install up to one (1) directory strip(s) for each 2,994 net rentable square feet in the Premises, listing the names and suite numbers of Tenant on the Building directory board to be placed in the main lobby of the Building. 7.4 CHARGES. Tenant shall pay to Landlord, monthly as billed, as additional Rent, such charges as may be separately metered or as Landlord may compute for the following: (a) any utility services utilized by Tenant for computers, data processing equipment or other electrical equipment in excess of that agreed to be furnished by Landlord pursuant to Section 7.1(e), (b) lighting installed in the Premises in excess of Building Standard lighting, or provided at times other than Building Standard Hours; (c) air-conditioning, heating and other services in excess of that stated in Section 7.1 (a) or provided at times other than Building Operating Hours; and (d) janitorial services required with respect to Non-Building Standard Items within the Premises. HVAC and lighting utilized at times other than Building Standard Hours will be furnished only upon the request of Tenant, provided that Tenant shall pay to the Landlord for the actual costs of such additional services monthly, upon receipt of a bill therefor, the sum equal to the amount charged to Landlord by the applicable utilities authority plus a $10.00 monthly service charge for such metering recording device. Tenant acknowledges that such service and temperature may be subject to change by local, county, state or federal regulation. Whenever machines or equipment that generate abnormal heat are used in the Leased Premises which affect the temperature otherwise maintained by the air conditioning system, Landlord shall have the right to install supplemental air conditioning in the Leased Premises, and the cost thereof, including the cost of installation, operating, use and maintenance, shall be paid by Tenant to Landlord as additional rental upon demand. With respect to any other Non-Building Standard services provided to Tenants Landlord may elect to estimate the charges to be paid by Tenant under this Section 7.4 and bill such charges to Tenant monthly in advance, in which event Tenant shall promptly pay the estimated charges. When the actual charges are determined by Landlord an appropriate cash adjustment shall be made between Landlord and Tenant to account for any underpayment or overpayment by Tenant. 7.5 OPERATING HOURS. Subject to Building Rules and Regulations and such security standards as Landlord may from time to time adopt, the Building shall be open to the public during the Building Operating Hours and the Premises shall be open to Tenant during hours other than Building Operating Hours. 8. REPAIR AND MAINTENANCE. 8.1 By Landlord. Landlord shall maintain the Building (excluding leasehold improvements which become fixtures thereto) in a good and operable condition, and shall make such repairs and replacements as may be required to maintain the Building in such condition. This Section 8.1 shall not apply to damage resulting from a Taking (as to which Section 14 shall apply), or damage resulting from a casualty (as to which Section 15.1 shall apply) or to damage for which Tenant is otherwise responsible under this Lease. 8.2 By Tenant. Tenant shall maintain the Premises in a clean, safe, operable, attractive condition, and will not commit or allow to remain any waste or damage to any portion of the Premises. Tenant shall repair or replace, subject to Landlord's direction and supervision, any damage to the Complex caused by Tenant or Tenant's agents, contractors or invitees. If Tenant fails to make such repairs or replacements, Landlord may make same at Tenant's cost. Such cost shall be payable to Landlord by Tenant on demand as additional Rent. All contractors, workmen, artisans and other persons which or who Tenant proposes to retain to perform work in the Premises (or the Complex, pursuant to the second sentence of this Section 8.2) pursuant to this Section 8.2 or Section 11 shall be approved by Landlord prior to the commencement of any such work. 9. TAXES ON TENANT'S PROPERTY. Tenant shall be liable for and shall pay, before their becoming delinquent, all taxes and assessments levied against any personal property placed by Tenant in the Premises (even if same becomes a fixture by operation of law or the property of Landlord by operation of this Lease), including any additional Impositions which may be assessed, levied, charged or imposed against Landlord or the Building by reason of Non-Building Standard Items in the Premises. Tenant may withhold payments of any taxes and assessments described in this Section 9 so long as Tenant contests its obligation to pay in accordance with applicable law and the non-payment thereof does not pose a threat of loss or seizure of the Building or any interest of Landlord therein. 10. TRANSFER BY TENANT. 10.1 GENERAL. Without the prior written consent of Landlord, Tenant shall not effect or suffer any Transfer. Any attempted Transfer without such consent shall be void. If Tenant desires to effect a Transfer, it shall deliver to Landlord written notice thereof in advance of the date on which Tenant proposes to make the Transfer, together with all of the terms of the proposed Transfer and the identity of the proposed Transferee. Landlord shall have 30 days following receipt of the notice and information within which to notify Tenant in writing whether Landlord elects (a) to refuse to consent to the Transfer and to terminate this Lease as to the space proposed to be Transferred as of the date so specified by Tenant, in which event Tenant will be relieved of all further obligations hereunder as to such space, (b) to refuse to consent to the Transfer and to continue this Lease in full force as to the entire Premises or (c) to permit Tenant to effect the proposed Transfer. If Landlord fails to notify Tenant of its election within said 30 day period, Landlord shall be deemed to have elected option (b). The consent by Landlord to a particular Transfer shall not be deemed a consent to any other Transfer. If a Transfer occurs without the prior written consent of Landlord as provided herein, Landlord may nevertheless collect rent from the Transferee and apply the net amount collected to the Rent payable hereunder, but such collection and application shall not constitute a waiver of the provisions hereof or a release of Tenant from the further performance of its obligations hereunder. 10.2 CONDITIONS. The following conditions shall automatically apply to each Transfer, without the necessity of same being stated in or referred to in Landlord's written consent: (a) Tenant shall execute, have acknowledged and deliver to Landlord, and cause the Transferee to execute, have acknowledged and deliver to Landlord, an instrument in form and substance acceptable to Landlord in which (i) the Transferee adopts this Lease and agrees to perform, jointly and severally with Tenant, all of the obligations of Tenant hereunder, as to the space transferred to it, (ii) the Transferee grants Landlord an express first and prior security interest in its personal property brought into the transferred space to secure its obligations to Landlord hereunder, (iii) Tenant subordinates to Landlord's statutory lien and security interest any liens, security interests or other rights which Tenant may claim with respect to any property of the Transferee, (iv) Tenant agrees with Landlord that, if the rent or other consideration due by the Transferee exceeds the Rent for the transferred space, then Tenant shall pay Landlord as additional Rent hereunder all such excess rent and other consideration immediately upon Tenant's receipt thereof, (v) Tenant and the Transferee agree to provide to Landlord, at their expense, direct access from a public corridor in the Building to the transferred space, (vi) the Transferee agrees to use and occupy the transferred space solely for the purpose specified in Section 4 and otherwise in strict accordance with this Lease and (vii) Tenant acknowledges that, notwithstanding the Transfer, Tenant remains directly and primarily liable for the performance of all the obligations of Tenant hereunder (including, without limitation, the obligation to pay all Rent), and Landlord shall be permitted to enforce this Lease against Tenant or the Transferee, or both, without prior demand upon or proceeding in any way against any other persons, and (b) Tenant shall deliver to Landlord a counterpart of all instruments relative to the Transfer executed by all parties to such transaction (except Landlord). 10.3 LIENS. Without in any way limiting the generality of the foregoing, Tenant shall not grant, place or suffer, or permit to be granted, placed or suffered, against the Complex or any portion thereof, any lien, security interest, pledge, conditional sale contract, claim, charge or encumbrance (whether constitutional, contractual or otherwise) and if any of the aforesaid does arise or is asserted, Tenant will, promptly upon demand by Landlord and at Tenant's expense, cause same to be released. 11. ALTERATIONS. Tenant shall not make, or permit to be made, any alteration, improvement or addition to, or install, or permit to be installed, any fixture or equipment (other than desk top electrical equipment) in, the Premises without the prior written consent of Landlord. All such alterations, improvements and additions (including all articles attached to the floor, wall or ceiling of the Premises) shall become the property of Landlord and shall, at Landlord's election, be (a) surrendered with the Premises as part thereof at the termination or expiration of the Term, without any payment, reimbursement or compensation therefor, or (b) removed by Tenant, at Tenant's expense, with all damage caused by such removal repaired by Tenant. Tenant may remove Tenant's trade fixtures, office supplies, movable office furniture and equipment not attached to the Building provided such removal is made within five days after the expiration of the Term, no uncured Event of Default has occurred and Tenant promptly repairs all damage caused by such removal. 12. SPECIFICALLY PROHIBITED USES. Tenant will not (a) use, occupy or permit the use or occupancy of the Premises for any purpose or in any manner which is or may be, directly or indirectly, violative of any Legal Requirement, or dangerous to life or property, or a public or private nuisance or disruptive or obstructive of any other tenant of the Building, (b) keep, or permit to be kept, any substance in or conduct, or permit to be conducted, any operation from the Premises which might emit offensive odors or conditions into other portions of the Building, or make undue noise or create undue vibrations, (c) commit or permit to remain any waste to the Premises, (d) install or permit to remain any improvements to the Premises (other than window coverings which have first been approved by Landlord) which are visible from the outside of the Premises, or exceed the structural loads of floors or walls of the Building, or adversely affect the mechanical, plumbing or electrical systems of the Building or affect the structural integrity of the Building in any way, (e) install any food, soft drink or other vending machine (other than those for the exclusive, non-commercial use of Tenant and its business invitees) in the Premises or (f) commit, or permit to be committed, any action or circumstance in or about the Building which, directly or indirectly, would or might justify any insurance carrier in canceling or increasing the premium on the fire and extended coverage insurance policy maintained by Landlord on the Building or contents, and if any increase results from any act of Tenant, then Tenant shall pay such increase promptly upon demand therefor by Landlord. 13. ACCESS BY LANDLORD. Landlord, its employees, contractors, agents and representatives, shall have the right (and Landlord, for itself and such persons and firms, hereby reserves the right) to enter the Premises at all hours (a) to inspect, clean, maintain, repair, replace or alter the Premises or the Building, (b) to show the Premises to prospective purchasers (or, during the last 12 months of the Term, to prospective tenants), (c) to determine whether Tenant is performing its obligations hereunder and, if it is not, to perform same at Landlord's option and Tenant's expense or (d) for any other purpose deemed reasonable by Landlord. In an emergency, Landlord (and such persons and firms) may use any means to open any door into or in the Premises without any liability therefor. Entry into the Premises by Landlord or any other person or firm named in the first sentence of this Section 13 for any purpose permitted herein shall not constitute a trespass or an eviction (constructive or otherwise), or entitle Tenant to any abatement or reduction of Rent, or constitute grounds for any claim (and Tenant hereby waives any claim) for damages for any injury to or interference with Tenant's business, for loss of occupancy or quiet enjoyment or for consequential damages. 14. CONDEMNATION. If all of the Complex is Taken, or if so much of the Complex is Taken that, in Landlord's opinion, the remainder cannot be restored to an economically viable, quality office building, or if the awards payable to Landlord as a result of any Taking are, in Landlord's opinion, inadequate to restore the remainder to an economically viable, quality office building, Landlord may, at its election, exercisable by the giving of written notice to Tenant within 60 days after the date of the Taking, terminate this Lease as of the date of the Taking or the date Tenant is deprived of possession of the Premises (whichever is later). If this Lease is not terminated as a result of a Taking, Landlord shall restore the Premises remaining after the Taking to a Building Standard condition. During the period of restoration, Base Rent shall be abated to the extent the Premises are rendered untenantable and, after the period of restoration, Base Rent and Tenant's Share shall be reduced in the proportion that the area of the Premises Taken or otherwise rendered untenantable bears to the area of the Premises just prior to the Taking. If any portion of Base Rent is abated under this Section 14, Landlord may elect to extend the expiration date of the Term for the period of the abatement. All awards, proceeds, compensation or other payments from or with respect to any Taking of the Complex or any portion thereof shall belong to Landlord, Tenant hereby assigning to Landlord all of its right, title, interest and claim to same. Tenant may assert a claim for and recover from the condemning authority, but not from Landlord, such compensation as may be awarded on account of Tenant's moving and relocation expenses, and depreciation to and loss of Tenant's moveable personal property. REMAINDER OF PAGE LEFT INTENTIONALLY BLANK. 15. CASUALTY. 15.1 GENERAL. Tenant shall give prompt written notice to Landlord of any casualty to the Complex of which Tenant is aware and any casualty to the Premises. If the Complex or the Premises are totally destroyed, or if the Complex or the Premises are partially destroyed but in Landlord's opinion, they cannot be restored to an economically viable, quality office building, or if the insurance proceeds payable to Landlord as a result of any casualty are, in Landlord's opinion, inadequate to restore the portion remaining to an economically viable and quality office building, Landlord may, at its election exercisable by the giving of written notice to Tenant within 60 days after the casualty, terminate this Lease as of the date of the casualty or the date Tenant is deprived of possession of the Premises (whichever is later). If this Lease is not terminated as a result of a casualty, Landlord shall (subject to Section 15.2) restore the Premises to a Building Standard condition. During the period of restoration, Base Rent shall be abated to the extent the Premises are rendered untenantable and, after the period of restoration, Base Rent and Tenant's Share shall be reduced in the proportion that the area of the Premises remaining tenantable after the casualty bears to the area of the Premises just prior to the casualty. If any portion of Base Rent is abated under this Section 15.1, Landlord may elect to extend the expiration date of the Term for the period of the abatement. 15.2 ACTS OF TENANT. Notwithstanding any provisions of this Lease to the contrary, if the Premises or the Complex are damaged or destroyed as a result of a casualty arising from the acts or omissions of Tenant, or any of Tenant's officers, directors, shareholders, partners, employees, contractors, agents, invitees or representatives, (a) Tenant's obligation to pay Rent and to perform its other obligations under this Lease shall not be abated, reduced or altered in any manner, (b) Landlord shall not be obligated to repair or restore the Premises or the Complex and (c) subject to Section 17.2, Tenant shall be obligated, at Tenant's cost, to repair and restore the Premises or the Complex to the condition they were in just prior to the damage or destruction under the direction and supervision of, and to the satisfaction of, Landlord and any Landlord Mortgagee. 16. SUBORDINATION AND ATTORNMENT. 16.1 GENERAL. This Lease, Tenant's leasehold estate created hereby and all of Tenant's rights, titles and interests hereunder and in and to the Premises are subject and subordinate to any Mortgage presently existing or hereafter placed upon all or any portion of the Complex. However, Landlord and Landlord's Mortgagee may, at any time upon the giving of written notice to Tenant and without any compensation or consideration being payable to Tenant, make this Lease, and the aforesaid leasehold estate and rights, titles and interests, superior to any Mortgage. Upon the written request by Landlord or by Landlord's Mortgagee to Tenant, and within five (5) days of the date of such request, and without any compensation or consideration being payable to Tenant, Tenant shall execute, have acknowledged and deliver a recordable instrument confirming that this Lease, Tenant's leasehold estate in the Premises and all of Tenant's rights, titles and interests hereunder are subject and subordinate (or, at the election of Landlord or Landlord's Mortgagee, superior) to the Mortgage benefiting Landlord's Mortgagee. 16.2 ATTORNMENT. Upon the written request of any person or party succeeding to the interest of Landlord under this Lease, Tenant shall automatically become the tenant of and attorn to such successor in interest without any change in any of the terms of this Lease. No successor in interest shall be (a) bound by any payment of Rent for more than one month in advance, except payments of security for the performance by Tenant of Tenant's obligations under this Lease, (b) subject to any offset, defense or damages arising out of a default or any obligations of any preceding Landlord or (c) bound by any amendment of this Lease entered into after Tenant has been given written notice of the name and address of Landlord's Mortgagee and without the written consent of Landlord's Mortgagee or such successor in interest. The subordination, attornment and mortgage protection clauses of this Section 16 shall be self-operative and no further instruments of subordination, attornment or mortgagee protection need be required by any Mortgagee or successor in interest thereto. Nevertheless, upon the written request therefor and without any compensation or consideration being payable to Tenant, Tenant agrees to execute, have acknowledged and deliver such instruments as maybe requested to confirm the same. 17.

Landlord and Tenant hereby waive all claims, rights of recovery and causes of action that either party or any party claiming by, through or under such party may now or hereafter have by subrogation or otherwise against the other party or against any of the other party's officers, directors, shareholders, partners or employees for any loss or damage that may occur to the Complex, the Premises, Tenant's improvements or any of the contents of any of the foregoing by reason of fire or other casualty, or by reason of any other cause except gross negligence or willful misconduct (THUS INCLUDING SIMPLE NEGLIGENCE OF THE PARTIES HERETO OR THEIR OFFICERS, DIRECTORS, SHAREHOLDERS, PARTNERS OR EMPLOYEES), that could have been insured against under the terms of (a) in the case of Landlord, the standard fire and extended coverage insurance policies available in the state where the Complex is located at the time of the casualty and (b) in the case of Tenant, the fire and extended coverage insurance policy required to be obtained and maintained under Section 17.1; provided, however, that the waiver set forth in this Section 17.2 shall not apply to any deductibles on insurance policies carried by Landlord or to any coinsurance penalty which Landlord might sustain. Landlord and Tenant shall cause an endorsement to be issued to their respective insurance policies recognizing this waiver of subrogation. 18. TENANT'S INDEMNITY. Subject to Section 17.2, Tenant shall defend, indemnify and hold harmless Landlord and Landlord's officers, directors, shareholders, partners and employees from and against, all liabilities, obligations, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements (including court costs and reasonable attorneys' fees) resulting from any injuries to or death of any person or damage to any property occurring during the Term in or about the Premises. 19. THIRD PARTIES; ACTS OF FORCE MAJEURE. Landlord shall have no liability to Tenant, or to Tenant's officers, directors, shareholders, partners, employees, agents, contractors or invitees, for bodily injury, death, property damage, business interruption, loss of profits, loss of trade secrets or other direct or consequential damages occasioned by (a) the acts or omissions of any other tenant or such other tenant's officers, directors, shareholders, partners, employees, agents, contractors or other invitees within the Complex, (b) Force Majeure, (c) vandalism, theft, burglary and other criminal acts (other than those committed by Landlord and its employees), (d) water leakage or (e) the repair, replacement, maintenance, damage, destruction or relocation of the Premises. 20. SECURITY INTEREST. As security for Tenant's payment of Rent and performance of all of its other obligations under this Lease, Tenant hereby grants to Landlord a security interest in all property of Tenant now or hereafter placed in the Premises. Landlord, as secured party, shall be entitled to all of the rights, remedies and recourses afforded to a secured party under the Texas Uniform Commercial Code, which rights, remedies and recourses shall be cumulative of all other rights, remedies, recourses, liens and security interests afforded Landlord by law, equity or this Lease. Contemporaneously with the execution of this Lease, Tenant shall execute and deliver, as debtor, promptly upon request and without any compensation or consideration being payable to Tenant, such additional financing statement or statements as Landlord may request. However, Landlord may at any time file a copy of this Lease as a financing statement. 21. CONTROL OF COMMON AREAS. Landlord shall have the exclusive control over the Common Areas. Landlord may, from time to time, create different Common Areas, close or otherwise modify the Common Areas, and modify and the Building Rules and Regulations with respect thereto. 22. RIGHT TO RELOCATE. Landlord retains the right and power, to be exercised reasonably and at Landlord's expense, to relocate Tenant within the Building in space which is comparable in size to the Premises and is suited to Tenant's use. Instances when the exercise of Landlord's right and power to relocate Tenant shall be deemed reasonable include, but shall not be limited to, instances where Landlord desires to consolidate the rentable area in the Building to provide Landlord's services more efficiently, or to provide contiguous vacant space for a prospective tenant. Landlord shall not be liable to Tenant for any claims arising in connection with a relocation permitted under this Section 22. 23. QUIET ENJOYMENT. Provided Tenant has performed all its obligations under this Lease, Tenant shall and may peaceably and quietly have, hold, occupy, use and enjoy the Premises during the Term subject to the provisions of this Lease. Landlord shall warrant and forever defend Tenant's right to occupancy of the Premises against the claims of any and all persons whomsoever lawfully claiming the same or any part thereof, by, through or under Landlord, but not otherwise, subject to the provisions of this Lease. 24. DEFAULT BY TENANT. 24.1 EVENTS OF DEFAULT. Each of the following occurrences shall constitute an Event of Default (herein so called): (a) The failure of Tenant to pay Rent as and when due hereunder and the continuance of such failure for a period of three days after written notice from Landlord to Tenant specifying the failure; provided, however, after Landlord has given Tenant written notice pursuant to this clause (a) on two separate occasions Landlord shall not be required to give Tenant any further notice under this clause (a); (b) The failure of Tenant to perform, comply with or observe any other agreement, obligation or undertaking of Tenant, or any other term, condition or provision, in this Lease, and the continuance of such failure for a period of ten days after written notice from Landlord to Tenant specifying the failure; (c) The abandonment of the Premises by Tenant or the failure of Tenant to occupy the Premises or any significant portion thereof, (d) The filing of a petition by or against Tenant (the term "Tenant" also meaning, for the purpose of this clause (d), any guarantor of the named Tenant's obligations hereunder) (i) in any bankruptcy or other insolvency proceeding, (ii) seeking any relief under the Bankruptcy Code or any similar debtor relief law, (iii) for the appointment of a liquidator or receiver for all or substantially all of Tenant's property or for Tenant's interest in this Lease or (iv) to reorganize or modify Tenant's capital structure; and (e) The admission by Tenant in writing that it cannot meet its obligations as they become due or the making by Tenant of an assignment for the benefit of its creditors. 24.2 REMEDIES OF LANDLORD. Upon any Event of Default, Landlord may, at Landlord's option and in addition to all other rights, remedies and recourses afforded Landlord hereunder or by law or equity, do any one or more of the following: (a) Terminate this Lease by the giving of written notice to Tenant, in which event Tenant shall pay to Landlord the sum of (i) all Rent and other amounts accrued hereunder to the date of termination, (ii) all amounts due under Section 24.3 and (iii) liquidated damages in an amount equal to (A) the total Rent that Tenant would have been required to pay for the remainder of the Term discounted to present value at the prime lending rate (or equivalent rate, however denominated) in effect on the date of termination at the largest national bank in the state where the Complex is located minus (B) the then present fair rental value of the Premises for such period, similarly discounted. (b) Terminate Tenant's right to possession of the Premises without terminating this Lease by the giving of written notice to Tenant, in which event Tenant shall pay to Landlord (i) all Rent and other amounts accrued hereunder to the date of termination of possession, (ii) all amounts due from time to time under Section 24.3 and (iii) all Rent and other sums required hereunder to be paid by Tenant during the remainder of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during said period. Reentry by Landlord in the Premises will not affect the obligations of Tenant hereunder for the unexpired Term. Landlord may bring action against Tenant to collect amounts due by Tenant on one or more occasions, without the necessity of Landlord's waiting until expiration of the Term. If Landlord elects to proceed under this Section 24.2(b), it may at any time elect to terminate this Lease pursuant to Section 24.2(a). (c) Without notice, alter any and all locks and other security devices at the Premises without being obligated to deliver new keys to the Premises, unless Tenant has cured all Events of Default before Landlord has terminated this Lease under Section 24.2(a) or has entered into a lease to relet all or a portion of the Premises. (d) If an Event of Default specified in Section 24.1 (c) occurs, Landlord may remove and store any property that remains on the Premises, and, if Tenant does not claim such property within ten days after Landlord has delivered to Tenant notice of such storage, Landlord may appropriate, sell, destroy, or otherwise dispose of the property in question without notice to Tenant or any other person and without any obligation to account for such property. 24.3 PAYMENT BY TENANT. Upon any Event of Default, Tenant shall also pay to Landlord all costs and expenses incurred by Landlord, including court costs and reasonable attorneys' fees, in (a) retaking or otherwise obtaining possession of the Premises, (b) removing and storing Tenant's or any other occupant's property, (c) repairing, restating, altering, remodeling or otherwise putting the Premises into condition acceptable to a new tenant or tenants, (d) reletting all or any part of the Premises, (e) paying or performing the underlying obligation which Tenant failed to pay or perform and (f) enforcing any of Landlord's rights, remedies or recourses arising as a consequence of the Event of Default. 24.4 RELETTING. Upon termination of this Lease or upon termination of Tenant's right to possession of the Premises, Landlord shall use reasonable efforts to relet the Premises on such terms and conditions as Landlord in its sole discretion may determine (including a term different than the Term, rental concessions, and alterations to, and improvements of, the Premises); however, Landlord shall not be obligated to relet the Premises before leasing other portions of the Building. Landlord shall not be liable, nor shall Tenant's obligations hereunder be diminished because of, Landlord's failure to relet the Premises or collect rent due in respect of such reletting. Tenant shall not be entitled to the excess of any rent obtained by reletting over the Rent herein reserved. 24.5 LANDLORD'S RIGHT TO PAY OR PERFORM. Upon an Event of Default, Landlord may, but without obligation to do so and without thereby waiving or curing such Event of Default, pay or perform the underlying obligation for the account of Tenant, and enter the Premises and expend the Security Deposit for such purpose. 24.6 NO WAIVER; NO IMPLIED SURRENDER. Provisions of this Lease may only be waived by the party entitled to the benefit of the provision evidencing the waiver in writing. Thus, neither the acceptance of Rent by Landlord following an Event of Default (whether known to Landlord or not), nor any other custom or practice followed in connection with this Lease, shall constitute a waiver by Landlord of such Event of Default or any other Event of Default. Further, the failure by Landlord to complain of any action or inaction by Tenant, or to assert that any action or inaction by Tenant constitutes (or would constitute, with the giving of notice and the passage of time) an Event of Default, regardless of how long such failure continues, shall not extinguish, waive or in any way diminish the rights, remedies and recourses of Landlord with respect to such action or inaction. No waiver by Landlord of any provision of this Lease or of any breach by Tenant of any obligation of Tenant hereunder shall be deemed to be a waiver of any other provision hereof, or of any subsequent breach by Tenant of the same or any other provision hereof. Landlord's consent to any act by Tenant requiring Landlord's consent shall not be deemed to render unnecessary the obtaining of Landlord's consent to any subsequent act of Tenant. No act or omission by Landlord (other than Landlord's execution of a document acknowledging such surrender) or Landlord's agents, including the delivery of the keys to the Premises, shall constitute an acceptance of a surrender of the Premises. 25. DEFAULTS BY LANDLORD. Landlord shall not be in default under this Lease, and Tenant shall not be entitled to exercise any right, remedy or recourse against Landlord or otherwise as a consequence of any alleged default by Landlord under this Lease, unless Landlord fails to perform any of its obligations hereunder and said failure continues for a period of 30 days after Tenant gives Landlord and (provided that Tenant shall have been given the name and address of Landlord's Mortgagee) Landlord's Mortgagee written notice thereof specifying, with reasonable particularity, the nature of Landlord's failure. If, however, the failure cannot reasonably be cured within the 30-day period, Landlord shall not be in default hereunder if Landlord or Landlord's Mortgagee commences to cure the failure within the 30 days and thereafter pursues the curing of same diligently to completion. If Tenant recovers a money judgment against Landlord for Landlord's default of its obligations hereunder or otherwise, the judgment shall be limited to Tenant's actual direct, but not consequential, damages therefor and shall be satisfied only out of the interest of Landlord in the Complex as the same may then be encumbered, and Landlord shall not otherwise be liable for any deficiency. In no event shall Tenant have the right to levy execution against any property of Landlord other than its interest in the Complex. The foregoing shall not limit any right that Tenant might have to obtain specific performance of Landlord's obligations hereunder. 26. RIGHT OF REENTRY. Upon the expiration or termination of the Term for whatever cause, or upon the exercise by Landlord of its right to re-enter the Premises without terminating this Lease, Tenant shall immediately, quietly and peaceably surrender to Landlord possession of the Premises in "broom clean" and good order, condition and repair, except only for ordinary wear and tear, damage by casualty not covered by Section 15.2 and repairs to be made by Landlord pursuant to Section 15.1. If Tenant fails to surrender possession as herein required, Landlord may, without giving Tenant prior notice to vacate the Premises or any other notice, initiate any and all legal action as Landlord may elect to dispossess Tenant and all of its property, and all persons or firms claiming by, through or under Tenant and all of their property, from the Premises, and may remove from the Premises and store (without any liability for loss, theft, damage or destruction thereto) any such property at Tenant's cost. While Tenant remains in possession of the Premises after such expiration, termination or exercise by Landlord of its re-entry right, Tenant shall be deemed to be occupying the Premises as a tenant-at-sufferance, subject to all of the obligations of Tenant under this Lease, except that the daily Rent shall be twice the per day Rent in effect immediately before such expiration, termination or exercise by Landlord. No such holding over shall extend the Term. If Tenant fails to surrender possession of the Premises in the condition herein required, Landlord may, at Tenant's expense, restore the Premises to such condition. 27. MISCELLANEOUS. 27.1 INDEPENDENT OBLIGATIONS; NO OFFSET. The obligations of Tenant to pay Rent and to perform the other undertakings of Tenant hereunder constitute independent unconditional obligations to be performed at the times specified hereunder, regardless of any breach or default by Landlord hereunder. Tenant shall have no right, and Tenant hereby waives and relinquishes all rights which Tenant might otherwise have, to claim any nature of lien against the Complex or to withhold, deduct from or offset against any Rent or other sums to be paid to Landlord by Tenant. 27.2 TIME OF ESSENCE. Time is of the essence with respect to each date or time specified in this Lease by which an event is to occur. 27.3 APPLICABLE LAW. This Lease shall be governed by, and construed in accordance with, the laws of the State of Texas. All monetary and other obligations of Landlord and Tenant are performable in the county where the Complex is located. 27.4 ASSIGNMENT BY LANDLORD. Landlord shall have the right to assign, in whole or in part, any or all of its rights, titles or interests in and to the Complex or this Lease and, upon any such assignment, Landlord shall be relieved of all unaccrued liabilities and obligations hereunder to the extent of the interest so assigned. 27.5 COMMENCEMENT DATE AND ESTOPPEL CERTIFICATES. From time to time at the request of Landlord or Landlord's Mortgagee, Tenant will promptly and without compensation or consideration execute, have acknowledged and deliver a certificate stating (a) the Commencement Date and the date of expiration of the Term, (b) the rights (if any) of Tenant to extend the Term or to expand the Premises, (c) the Rent (or any components of the Rent) currently payable hereunder, (d) whether this Lease has been amended in any respect and, if so, submitting copies of or otherwise identifying the amendments, (e) whether, within the knowledge of Tenant, there are any existing breaches or defaults by Landlord hereunder and, if so, stating the defaults with reasonable particularity and (f) such other information pertaining to this Lease as Landlord or Landlord's Mortgagee may reasonably request. 27.6 SIGNS, BUILDING NAME AND BUILDING ADDRESS. Landlord may, from time to time at its discretion, maintain any and all signs anywhere in the Complex, and to change the name and street address of the Complex. Tenant shall not use the name of the Building for any purpose other than as the address of the business to be conducted by Tenant from the Premises. 27.7 NOTICES. All notices and other communications given pursuant to this Lease shall be in writing and shall either be mailed by first class United States mail, postage prepaid, registered or certified with return receipt requested, and addressed as set forth in this Section 27.7, or delivered in person to the intended addressee, or sent by prepaid telegram, cable or telex followed by a confirmatory letter. Notice mailed in the aforesaid manner shall become effective three business days after deposit; notice given in any other manner, and any notice given to Landlord, shall be effective only upon receipt by the intended addressee. Each party shall have the continuing right to change its address for notice hereunder by the giving of 15 days' prior written notice to the other party in accordance with this Section 27.7.

Any termination of the Lease during the initial lease Term shall terminate all renewal rights hereunder. The renewal rights of Tenant hereunder shall not be severable from the Lease, nor may such rights be assigned or otherwise conveyed in connection with any permitted assignment of the Lease. Landlord's consent to any assignment of the Lease shall not be construed as allowing an assignment of such rights to any assignee.
