Landlord shall estimate the Operating Costs and Taxes of the Project by April 1 of each calendar year, or as soon as reasonably possible thereafter. Landlord may revise these estimates whenever it obtains more accurate information, such as the final real estate tax assessment or tax rate for the Project. Until Landlord provides such an estimate for a calendar year, Tenant shall continue paying installments of estimated Tax Share Rent and Operating Cost Share Rent as provided below based on Landlord's most recent estimates for the previous calendar year.

Within ten (10) days after receiving the original or revised estimate from Landlord setting forth (i) an estimate of Operating Costs for a particular calendar year, (ii) the Base Operating Costs, and (iii) the resulting estimate of Excess Operating Costs for such calendar year, Tenant shall pay Landlord one-twelfth (l/12th) of Tenant's Proportionate Share of the estimated Excess Operating Costs, multiplied by the number of months that have elapsed in the applicable calendar year prior to the date of such payment including the current month, minus payments previously made by Tenant for the months elapsed. On the first day of each month thereafter, Tenant shall pay Landlord one-twelfth (l/12th) of Tenant's Proportionate Share of this estimate, until a new estimate becomes applicable.

Within ten (10) days after receiving the original or a revised estimate from Landlord setting forth (i) an estimate of Taxes for a particular calendar year, (ii) the Base Taxes, and (iii) the resulting estimate of Excess Taxes for such calendar year, Tenant shall pay Landlord one-twelfth (l/12th) of Tenant's Proportionate Share of the estimated Excess Taxes, multiplied by the number of months that have elapsed in the applicable calendar year to the date of such payment including the current month, minus payments previously made by Tenant for the months elapsed.

Landlord shall deliver to Tenant a report for the previous calendar year (the 'Tax Report") by May 15 of each year, or as soon as reasonably possible thereafter, setting forth (i) the actual Taxes, (ii) the Base Taxes, (iii) the amount of Tax Share Rent due from Tenant, and (iv) the amount of Tax Share Rent paid by Tenant.

2.3 Definitions.

(a) Included Operating Costs. "Operating Costs" means all expenses, costs and disbursements of any kind other than Taxes, paid or incurred by Landlord in connection with the management, maintenance, operation, insurance, repair and other related activities in connection with any part of the Project and of the personal property, fixtures, machinery, equipment, systems and apparatus used in connection therewith, including the cost of providing those services required to be furnished by Landlord under this Lease. Operating Costs shall also include the costs of any capital improvements which are intended to reduce Operating Costs or improve safety, and those made to keep the Project in compliance with governmental requirements applicable from time to time (collectively, 'Included Capital Items"): provided, that the costs of any Included Capital Item shall be amortized by Landlord, together with an amount equal to interest at eleven percent (11%) per annum, over the estimated useful life of such item regardless of whether such item remains in service a longer or shorter period, and only the amortized amount for any calendar year shall be included in Operating Costs for such calendar year.

If the Project is not fully occupied during any portion of any calendar year, Landlord may adjust (an '"Equitable Adjustment") Operating Costs which are affected by the occupancy rate for the particular calendar year to reflect an occupancy of 95% of the Building rentable area, provided however that if Landlord makes such an Equitable Adjustment, and if during the Base Year the Project is not fully occupied, then Landlord shall make this same adjustment with respect to the Base Year hereunder. This Equitable Adjustment shall apply only to Operating Costs which are variable and therefore increase as occupancy of the Project increases. Landlord may incorporate the Equitable Adjustment in its estimates of Operating Costs.

If Landlord does not furnish any particular service the cost of which would have constituted an Operating Cost to a tenant other than Tenant who has undertaken to perform such service itself, Operating Costs shall be increased by the amount which Landlord would have incurred if it had furnished the service to such tenant.

(b) Excluded Operating Costs. Operating Costs shall not include:

(1) costs of alterations of tenant premises;

(2) costs of capital improvements other than Included Capital Items;

(3) interest and principal payments on mortgages or any other debt costs, or rental payments on any ground lease of the Project;

(4) real estate brokers' leasing commissions;

(5) legal fees, space planner fees and advertising expenses incurred with regard to leasing the Building or portions thereof;

(6) any cost or expenditure for which Landlord is reimbursed, by insurance proceeds or otherwise, except by Operating Cost Share Rent;

(7) the cost of any service furnished to any office tenant of the Project which is specifically excluded from services Landlord is obligated to provide under this Lease;

(8) depreciation (except on any Included Capital Items);

(9) legal or other professional fees incurred to enforce leases against tenants;

(10) legal and auditing fees incurred by Landlord in connection with forming, maintaining, and operating the entity that comprises Landlord, but not legal and auditing fees directly related to the management and operation of the Building and not otherwise excluded from operating costs in this Section 2.3(b): and

(11) the wages of any employee for services not related directly to the management, maintenance, operation and repair of the Building.

(c) Taxes. 'Taxes" means any and all taxes, assessments and charges of any kind, general or special, ordinary or extraordinary, levied against the Project, which Landlord pays or becomes obligated to pay in connection with the ownership, leasing, renting, management, use, occupancy, control or operation of the Project or of the personal property, fixtures, machinery, equipment, systems and apparatus used in connection therewith. Taxes shall include real estate taxes, personal property taxes, sewer rents, water rents, special or general assessments, transit taxes, ad valorem taxes, and any tax levied on the rents hereunder or the interest of Landlord under this Lease (the "Rent Tax"). Taxes shall also include all fees and other costs and expenses paid by Landlord in reviewing any tax and in seeking a refund or reduction of any Taxes, whether or not the Landlord is ultimately successful. Any refund or other adjustment to any Taxes by the taxing authority, shall apply during the year in which the adjustment is made. Taxes shall not include any net income (except Rent Tax), capital, stock, succession, transfer, franchise, gift, estate or inheritance tax, except to the extent that such tax shall be imposed in lieu of any portion of Taxes.

(d) Lease Year. "Lease Year" means each consecutive twelve-month period beginning with the Commencement Date, except that if the Commencement Date is not the first day of a calendar month, then the first Lease Year shall be the period from the Commencement Date through the final day of the twelve months after the first day of the following month, and each subsequent Lease Year shall be the twelve months following the prior Lease Year.

2.4 Computation of Base Rent and Rent Adjustments.

(a) Prorations. If this Lease begins on a day other than the first day of a month, the Base Rent, Operating Cost Share Rent and Tax Share Rent shall be prorated for such partial month based on the actual number of days in such month. If this Lease begins on a day other than the first day, or ends on a day other than the last day, of the calendar year, Operating Cost Share Rent and Tax Share Rent shall be prorated for the applicable calendar year.

(b) Rent Adjustments. The rentable square footage of the Premises and the Building set forth hi the Schedule are conclusively deemed to be the actual square footage thereof. If any Operating Cost paid in one calendar year relates to more than one calendar year, Landlord may equitably allocate such Operating Cost among the applicable calendar years.

(c) Books and Records. Landlord shall maintain books and records reflecting the Operating Costs and Taxes in accordance with sound accounting and management practices. Tenant and its certified public accountant shall have the right to inspect Landlord's records at Landlord's office upon at least seventy-two (72) hours' prior notice during normal business hours for ninety (90) days following the respective delivery of the Operating Cost Report or the Tax Report. The results of any such inspection shall be kept strictly confidential by Tenant and its agents, and Tenant and its certified public accountant must agree, in their contract for such services, to such confidentiality restrictions and shall specifically agree that the results shall not be made available to any other tenant of the Building. Unless Tenant delivers to Landlord any written notice of exception to either such report within said ninety (90) day period, such reports shall be deemed final and accepted by Tenant, Tenant shall pay the amount shown on both reports in the manner prescribed in this Lease, whether or not Tenant takes any such written exception, without any prejudice to such exception. If Tenant makes a timely exception, Landlord shall cause its independent certified public accountant or shall select and cause another firm with at least five (5) years of experience in auditing the books and records of commercial office projects to issue a final and conclusive resolution of Tenant's exception. Tenant shall pay the cost of such certification as Additional Rent unless Landlord's original annual Operating Cost Report or Tax Report overstated the amount of Operating Costs or Taxes, as applicable, by more than five percent (5%).

(d) Miscellaneous. So long as Tenant is in default of any obligation under this Lease, Tenant shall not be entitled to any refund of any amount from Landlord. If this Lease is terminated for any reason prior to the annual determination of Operating Cost Share Rent or Tax Share Rent, either party shall pay the full amount due to the other within fifteen (15) days after Landlord's notice to Tenant of the amount when it is determined. Landlord shall not be obligated to keep amounts paid by Tenant on account of Operating Cost Share Rent or Tax Share Rent separate from other kinds of Rent or each other, and all such payments become the property

of Landlord when paid. The provisions of this Section 2 shall survive the expiration or other termination of this Lease.

3.1 Condition of Premises. Tenant accepts the Premises in their existing condition, AS IS, and Landlord shall have no obligation to make any improvements in or changes to the Premises.

3.2 Tenant's Possession, Tenant's taking possession of any portion of the Premises shall he conclusive evidence that the Premises were in good order, repair and condition.

However, in the event that an interruption of the Project services set forth in this Section 4 is within Landlord's reasonable control and such interruption causes the Premises to be untenantable for a period of five (5) or more consecutive business days, monthly installments of Base Rent after such period shall be abated (determined on a prorated daily basis) until such services are restored.

Landlord, its agents, and employees make no representation that the limits of liability specified to be carried by Tenant pursuant to this Section 8.3 are adequate to protect Tenant, and in no event shall the limits of liability specified herein limit Tenant's liability under this Lease. If Tenant believes that any of such insurance coverage is inadequate, Tenant will obtain such additional insurance coverage as Tenant deems adequate, at Tenant's sole expense.

8.4 Insurance Certificates. Tenant shall deliver to Landlord certificates evidencing all required insurance no later than five (5) days prior to the Commencement Date and each renewal date. Each certificate shall provide for thirty (30) days prior written notice of cancellation to Landlord and Tenant.

and conditions as are normally carried by reasonably prudent owners of properties similar to the Project.

8.6 Waiver of Subrogation. Landlord and Tenant agree to obtain and maintain throughout the term of this Lease endorsements to their respective All Risk coverage policies waiving the right of subrogation of their insurance companies against the other party and its agents and employees. Such waiver of subrogation will be effective with respect to loss or damage occurring only during such time as Landlord's and Tenant's policies will be in force and effect with respect to such loss or damage. Such policies will contain a clause or endorsement to the effect that any such waiver will not adversely affect or impair such policies or prejudice the right of the waiving party to recover under such policies.

9. FIRE AND OTHER CASUALTY.

9.1 Termination.

(a) If a fire or other casualty causes substantial damage to the Building or the Premises, and insurance proceeds have been made available to Landlord to repair the damage by the insurer and any Master Lessor or Mortgagee, then Landlord shall engage an architect to certify within one (1) month of the casualty to both Landlord and Tenant the amounts of time needed to restore (i) the Building and (ii) the Premises to tenantability, using standard working methods.

(b) (1) If the time certified by such architect with respect to the Premises exceeds one hundred eighty (180) days from the beginning of the restoration, or if the restoration would begin during the last eighteen (18) months of the Lease, then either Landlord or Tenant may terminate this Lease by giving notice to the other within thirty (30) days of the date Landlord gives Tenant notice of the architect's certification.

(2) If the time certified by such architect with respect to the Building (but not the Premises) exceeds one hundred eighty (180) days from the beginning of the restoration, or if the restoration would begin during the last eighteen (18) months of the Lease, Landlord may terminate this Lease by giving notice to Tenant within thirty (30) days of the date Landlord gives Tenant notice of the architect's certification.

(c) If insurance proceeds are not made available to Landlord by the insurer or any Master Lessor or Mortgagee or if the casualty is the Building and Landlord determines it would be uneconomical to reconstruct or repair the damage, then Landlord may terminate this Lease by notice to Tenant within thirty (30) days after the casualty. The termination shall be effective thirty (30) days from the date of the notice and Rent shall be paid by Tenant to that date, with an abatement for any portion of the Premises which has been rendered untenantable by the casualty.

9.2 Restoration. If a casualty causes damage to the Building or the Premises but this Lease is not terminated for any reason, then subject to the rights of any Mortgagees or Master Lessors, Landlord shall obtain the applicable insurance proceeds and diligently restore the Building and the Premises to the extent of such proceeds. Landlord shall have the right to adapt the restoration of the Premises to comply with Governmental Requirements that are then in

effect. Landlord shall not be required to restore Tenant's personal property or trade fixtures or any Work performed by or on behalf of Tenant pursuant to Section 5.1 above. Rent shall be abated on a per diem basis during the restoration for any portion of the Premises which is untenantable, except to the extent that Tenant's negligence, breach of this Lease, or intentional conduct caused the casualty,

10. EMINENT DOMAIN.

10.1 Taking. If (i) the entire Premises; (ii) so much of the Premises as renders the balance unusable by Tenant; or (iii) so much of the Building apart from the Premises as renders the Premises unusable by Tenant, shall be taken by condemnation, sale in lieu of condemnation or in any other manner for any public or quasi-public purpose (collectively "Condemnation"), this Lease shall terminate on the date that title or possession to the Premises is taken by the condemning authority, whichever is earlier (the "Date of Taking"). If a material portion of the Project other than the Premises shall be taken by Condemnation which does not automatically terminate this Lease pursuant to the foregoing sentence, Landlord shall have the right, exercisable by written notice to Tenant delivered by the thirtieth (30th) day after the Date of Taking, to terminate this Lease. If a portion of the Premises shall be taken by Condemnation which does not automatically terminate this Lease pursuant to the first sentence of this Section 10.1. this Lease shall automatically terminate as to such portion of the Premises taken, if any, on the Date of Taking, Rent payable hereunder that is computed based on the area of the Premises shall be adjusted in proportion to the amount of space taken, and Landlord shall have the right, exercisable by written notice to Tenant delivered within thirty (30) days after the Date of Taking, to terminate this Lease as to the remainder of the Premises.

10.2 Award. The entire award for a Condemnation of any kind shall belong to Landlord, and Tenant shall have no right to share in the award, except that Tenant shall be entitled to independently pursue a separate award relating to the loss of, or damage to, Tenant's personal property and trade fixtures and Tenant's relocation costs directly associated with the taking; provided that in no event shall Tenant's separate award reduce the amount of Landlord's award. All obligations accrued to the Date of Taking shall be performed by the party liable to perform said obligations, as set forth herein. Tenant shall have no claim against Landlord or the award for the value of any unexpired term of this Lease or otherwise,

10.3 Temporary Taking. No temporary taking of the Premises or Building shall terminate this Lease or entitle Tenant to any abatement of the Rent payable to Landlord under this Lease; provided, further, that any award for such temporary taking with respect to the Premises shall belong to Tenant to the extent that the award applies to any time period during the Term and to Landlord to the extent that the award applies to any time period outside the Term.

13. LANDLORD REMEDIES. Upon the occurrence of an Event of Default, Landlord shall have the option to pursue any one or more of the remedies available at law, in equity, or under this Lease, without any further notice or demand whatsoever, including without limitation the remedies set forth in the following Sections 13.1. 13.2, and I3..3:

13.1 Terminate Lease. Landlord may terminate this Lease, effective at such time as may be specified by notice to Tenant, in which event:

(a) Tenant shall remain liable to Landlord for all obligations under this Lease accruing through the time of termination including the full amount of the current month's installment of Rent (unless previously paid), which shall immediately become due and payable, together with any arrears unpaid.

(b) Landlord may, with or without process of law, reenter upon and take possession of the Premises.

(c) Landlord may at Tenant's expense, at any time Landlord is entitled to possession of the Premises, remove and store such goods, chattels, fixtures, trade fixtures, and equipment of Tenant as are in the Premises in any manner Landlord may, in its discretion, determine, and Landlord shall have no liability to Tenant for such removal and storage, and Tenant shall reimburse Landlord for all costs incurred by Landlord in connection therewith.

(d) Landlord may recover from Tenant as damages, for the loss of income of Landlord expected to be derived from the Lease, the amounts (if any) by which (i) the Rent which would have been payable under this Lease exceeds (ii) the remainder obtained when all of Landlord's Reletting Costs, as hereinafter defined, which have not been paid by Tenant to Landlord are deducted from the payments (if any) received by Landlord from reletting the Premises. Such amounts shall be payable on the first day of each month during the period which would have constituted the unexpired portion of the Term had it not been terminated. As used herein, "Reletting Costs" shall mean all costs and expenses, including, without limitation, reasonable attorneys' fees, brokerage or other commissions, costs of repair or remodeling of the Premises, of subdividing the Premises, or of combining all or any portion or portions of the

Premises with other premises in any manner Landlord shall deem appropriate, lease assumption costs, and the costs of other tenant inducements, which Landlord may incur in connection with any reletting of the Premises pursuant to this Section 13.

(e) Landlord may, at its option, at any time, declare immediately due and payable the unamortized portion of any improvement allowance and other out-of-pocket costs (including without limitation brokerage commissions) incurred by Landlord in connection with this Lease, all of which shall, upon such declaration, immediately be due and payable in full by Tenant. Such amortization shall be computed on a straight-line basis over the Term of the Lease with interest at the rate of 9% per annum beginning with the first full calendar month of the Term, but without payments being amortized during any part of the Term in which Rent may be abated. To the extent any portion of such unamortized costs is paid by Tenant pursuant to this Subsection, such portion shall be excluded from the amount of Rent which would have been otherwise payable hereunder for purposes of calculating Landlord's damages under this Section 13.

(f) Landlord may recover from Tenant, as damages, a lump sum which is the remainder obtained when the amount determined pursuant to the following Subsection (1) is subtracted from the amount determined pursuant to the following Subsection (2).

(1) The Rent which would have been payable under this Lease from the effective date of termination through the date on which the Term would have expired had this Lease not been terminated, reduced to present value by the per annum rate which is one percent per annum higher than the then-current discount rate of the Federal Reserve Bank in San Francisco (the "PV Rate"), compounded annually,

(2) The present value, calculated by applying the PV Rate thereto, compounded annually, of the fair rental value of the Premises from the effective date of termination through the date on which the Term would have expired had the Lease not been terminated, less the Reletting Costs incurred by Landlord which have, as of such effective date, not yet been paid by Tenant to Landlord, also adjusted to present value at such rate.

13,2 Termination of Possession Without Terminating Lease. Landlord, may, without terminating this Lease, terminate Tenant's right to possession of the Premises, in which event:

(a) Landlord may, with or without process of law, retake possession of the Premises.

(b) Landlord may remove and deal with Tenant's goods, chattels, fixtures, trade fixtures, equipment, and other property as permitted by Section 13.1 (c).

(c) Tenant's obligations under this Lease (including the obligation to pay Rent on the dates specified in this Lease) shall continue unaffected for the Term or until such earlier time as Landlord may, at its option, elect to terminate this Lease which Landlord may, at its option, do at any time.

(d) Without being deemed to have elected to terminate this Lease, Landlord may relet the Premises in accordance with Section 1.3.5 below for the account of Tenant, in the name of Landlord or in the name of Tenant on such terms and conditions and to such tenants as Landlord may, in its discretion, determine. Landlord shall be entitled to remodel and repair the Premises, to subdivide the Premises, or to combine all or any portion or portions of the Premises with other premises in any manner which Landlord shall deem appropriate in order to accomplish such reletting; and Tenant shall reimburse Landlord, on demand, for all costs and expenses in connection with such repair or remodeling and reletting. Notwithstanding Landlord's recovery of possession and notwithstanding any reletting, Tenant shall continue to pay all Rent provided for herein as and when it comes due, less the net proceeds received by Landlord from any reletting; provided that, if the proceeds of reletting exceed the amount due from Tenant, on or before the 15th day of each month, Landlord shall refund to Tenant any amount by which the Rent paid by Tenant through such date, when added to the amount, if any, recovered by Landlord through any reletting of the Premises through such date, reduced by all Reletting Costs for which Tenant has not paid Landlord, and reduced by all amounts Landlord has previously refunded to Tenant under this Subsection, and reduced by any other amounts Tenant owes Landlord under this Lease, exceeds the Rent due under this Lease through such date. Tenant shall reimburse Landlord upon demand for all Reletting Costs and any other costs and expenses which Landlord may incur in connection with recovery of possession or repair of the Premises.

(f) In the event Landlord proceeds under this Section 13.2. Landlord may at any time terminate this Lease by notice to Tenant. Such termination shall have the effect specified in Section 13.1 and Landlord shall be entitled to all remedies under Section 13.1 upon termination.

13.3 General Remedies. Regardless of whether Landlord elects to terminate the Lease pursuant to Section 13.1, to terminate Tenant's right of possession pursuant to Section 13.2, or to take no immediate action with respect to Tenant's possession, Landlord shall have the following remedies:

(a) Landlord may continue to collect Rent as it comes due under the Lease.

(b) Landlord may bring separate or consolidated actions from time to time to collect any one or more delinquent installments or payments of Rent due under this Lease or to

enforce any right or remedy provided under this Lease or otherwise available at law or in equity; provided that Landlord shall not be entitled to accelerate or advance to a date before they would otherwise come due any of Tenant's obligations under this Lease except pursuant to Sections 13.1(e), 13,I(f), 13.2(e). or as otherwise specifically and expressly provided in this Lease,

(c) Landlord may (but shall not be obligated to) perform any act that Tenant shall be required and shall fail to perform hereunder. Landlord's performance shall not constitute a waiver or cure of Tenant's default or release Tenant from any of its obligations relative thereto. All sums paid or costs incurred by Landlord in so performing such acts under this Section 13. together with interest thereon at the Default Rate from the date such payment was made or such cost was incurred by Landlord, shall be payable by Tenant to Landlord on demand as Additional Rent.

13.4 Remedies Cumulative. No reference to or exercise of any specific right or remedy by Landlord shall prejudice or preclude Landlord from exercising or invoking any other remedy in respect thereof, whether allowed at law or in equity or expressly provided for herein, except to the extent, if any, expressly limited by the provisions of this Lease. No such remedy shall be exclusive or dependent upon any other such remedy, but either party may from time to time exercise any one or more of such remedies independently or in combination. Acceptance of payment by Landlord after commencement of a legal proceeding or final judgment shall not affect such proceeding or judgment. Landlord may advance such monies and take such other actions for Tenant's account as reasonably may be required to cure or mitigate any default by Tenant. Tenant shall immediately reimburse Landlord for any such advance, and such sums shall bear interest at the default interest rate until paid.

13.5 Landlord's Obligations Regarding Reletting. Landlord shall have no duty to attempt to mitigate its damages by retaking and reletting the Premises; provided that, if Landlord retakes possession of the Premises under either Section 13.1 or Section 13.2. Landlord shall use good faith reasonable efforts to relet the Premises, subject to the following terms, conditions and limitations:

(a) Any reletting of the Premises shall be on the terms and conditions determined by Landlord in its reasonable good faith discretion and to such tenants as Landlord shall approve in its reasonable good faith discretion. Without limiting the generality of the foregoing, Tenant acknowledges that, in reletting the Premises, Landlord may legitimately consider the effect of any such reletting on the Building and on any other buildings owned by Landlord or any other person or entity controlling, controlled by, or under common control with Landlord, or otherwise affiliated with Landlord (which parties are referred to in this Section 13 collectively as "Landlord Affiliates"), and, therefore, may decide not to lease the Premises at rates which are lower than Landlord is otherwise endeavoring to maintain in the Building, or at rates which are lower than the rate that Landlord believes to be appropriate for the Premises.

(b) Tenant recognizes that Landlord and Landlord's Affiliates currently and in the future may have vacant space in the Building and other buildings and may in the future also have vacant space in new projects in competition with the Premises. In no event shall Landlord be obligated to use any effort to relet the Premises in preference to leasing any such other vacant space then available for leasing by Landlord or any of Landlord's Affiliates. Landlord shall not

be deemed to have failed to mitigate damages solely on account of the leasing of other space which Landlord or Landlord's Affiliates have available instead of the reletting of the Premises.

13.6 Termination of Subleases and Other Arrangements. Whether or not Landlord elects to terminate this Lease on account of any Event of Default by Tenant, and subject to Landlord's duty to attempt to mitigate its damages as provided herein, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord's sole discretion, succeed to Tenant's interest in such subleases, licenses, concessions or arrangements. In the event of Landlord's election to succeed to Tenant's interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder, except that amounts actually received by Landlord thereunder shall be credited against any amounts payable by Tenant hereunder.

13.7 Interest and Costs. Tenant shall pay monthly to Landlord interest at a rate (the "Default Rate") equal to the lesser of 1.5% per month or the maximum rate permitted by applicable law, on all amounts required to be paid under this Lease from the due date for payment thereof (without grace) until the same is fully paid and satisfied; provided that, in the event of the existence of a good faith dispute between Landlord and Tenant with regard to any amount payable by Tenant under this Lease, which amount does not constitute Base Rent or Operating Costs, if it is finally determined that an amount is payable by Tenant to Landlord, Tenant shall promptly pay such amount to Landlord, together with interest thereon from the date such amount was originally due until fully paid at a per annum rate equal to the sum of (i) 2% per annum plus (ii) the per annum prime lending rate from time to time announced by Xxxxx Fargo Bank, N.A. or its successor, or, if Xxxxx Fargo Bank, N.A. or its successor ceases to report such a prime lending rate, the per annum prime lending rate of another national bank doing business in Colorado designated by Landlord (the 'Prime Rate"). Tenant shall indemnify Landlord against all costs and charges (including reasonable attorneys' fees) incurred in enforcing payment thereof. In the event of the existence of a good faith dispute between Landlord and Tenant concerning the applicability of any provision of this Lease providing for an abatement of Rent, or any portion thereof, Tenant shall nonetheless continue to pay such Rent to Landlord and, if it is finally determined that any amount actually paid by Tenant to Landlord was subject to abatement, such amount shall be repaid by Landlord to Tenant together with interest thereon from the date of Landlord's receipt of such amount until fully paid at a per annum rate equal to the sum of 2% per annum plus the Prime Rate.

13.8 Late Charges. In addition to default interest under Action 13,7. payments of any amount required to be paid under this Lease by Tenant which are not received by Landlord by the 5th day after the date they are due shall be subject to a late charge of 5% of the amount due. If Landlord does not receive any payment of Rent on or before the dates set forth in this Lease on more than two occasions in any Lease Year, then in addition to the late charges provided above, Tenant shall pay a habitual late charge of 5% for every payment received by Landlord after the first day of each subsequent month, until all payments of Rent have been received by Landlord on or before the first day of every subsequent month for at least 12 consecutive months. Tenant acknowledges that late payments will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which would be impossible or extremely difficult to ascertain. Those

costs include processing and accounting charges, interest and late charges imposed by Mortgagees or Master Lessors, and other general and administrative expenses. Tenant agrees that the late charges and interest contemplated by this Section represent a fair and reasonable estimate of the costs which Landlord will incur as a result of any such late payments by Tenant. Acceptance of late charges and interest by Landlord shall not constitute a waiver of Tenant's default with respect to any overdue amount, or prevent Landlord from exercising any other rights or remedies under this Lease.

13.9 WAIVER OF TRIAL BY JURY. Landlord and Tenant hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other on any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant's use or occupancy of the Premises, any claim of injury or damage, or the enforcement of any remedy under any statute, emergency or otherwise.

14. ATTORNEYS' FEES AND COSTS OF SUIT.

14.1 Attorneys' Fees and Costs. If Tenant or Landlord commences any action or other proceeding against the other arising out of or relating to this Lease or the Premises, the party, if any, prevailing on the more substantial part of its claims and defenses shall be entitled to recover from the other party its attorneys' fees and costs of suit in addition to any other relief, irrespective of whether the action or other proceeding is prosecuted to judgment. In addition, Tenant shall reimburse Landlord, upon demand, for all reasonable attorneys' fees and costs incurred in collecting Rent or otherwise seeking enforcement against Tenant, and/or its sublessees and assigns, of Tenant's obligations under this Lease.

14.2 Indemnification. Should Landlord be made a party to any litigation instituted by Tenant against a party other than Landlord, or by a third party against Tenant, Tenant shall indemnify, hold harmless and defend Landlord from any and all loss, cost, liability, damage or expense incurred by Landlord, including attorneys' fees and costs of suit, in connection with the litigation.

15. SURRENDER. Upon termination of this Lease or Tenant's right to possession, Tenant shall return the Premises to Landlord in good order and condition, ordinary wear and casualty damage excepted. If Landlord requires Tenant to remove any alterations, then Tenant shall remove the alterations in a good and workmanlike manner and restore the Premises to its condition prior to their installation.

16. HOLDOVER, Tenant shall have no right to holdover possession of the Premises after the expiration or termination of this Lease without Landlord's prior written consent, which consent may be withheld in Landlord's sole and absolute discretion. If Tenant retains possession of any part of the Premises after the Term with consent of Landlord, Tenant shall become a month-to-month tenant for the entire Premises upon all of the terms of this Lease (except those that are inconsistent with month-to-month tenancy), except that Tenant shall pay Base Rent at 150% of the rate for Base Rent in effect immediately prior to such holdover, computed on a monthly basis for each full or partial month Tenant remains in possession. If Tenant retains possession of any part of the Premises after the Term without consent of Landlord, Tenant shall become tenant at sufferance for the entire Premises upon all of the terms of this Lease (except

those that are inconsistent with tenancy at sufferance), except that Tenant shall pay Base Rent at 150% of the rate for Base Rent in effect immediately prior to such holdover, computed on a monthly basis for each full or partial month Tenant remains in possession. Tenant shall also pay Landlord all of Landlord's direct and consequential damages resulting from Tenant's holdover. No acceptance of Rent or other payments by Landlord under these holdover provisions shall operate as a waiver of Landlord's right to regain possession of the Premises or any of Landlord's other rights or remedies.

17. SUBORDINATION TO GROUND LEASES AND MORTGAGES.

17.1 Subordination. This Lease, and the rights of Tenant hereunder, are and shall be subject and subordinate to the interests of (i) all present and future ground leases and master leases (collectively, "Superior Leases") of all or any part of the Project; (ii) present and future mortgages and deeds of trust encumbering all or any part of the Project (collectively, "Mortgages"); (iii) all past and future advances made under any such Mortgages; and (iv) all renewals, modifications, replacements and extensions of any such Superior Leases or Mortgages; provided, however, that any lessor under any such Superior Lease (each, a "Master Lessor") or any mortgagee or beneficiary under any such Mortgage (each, a "Mortgagee") shall have the right, at any time and from time to time, to elect, by written notice given to Tenant, to have this Lease made superior in whole or in part to any such Superior Lease or Mortgage or to subordinate this Lease to any such Superior Lease or Mortgage, Within ten (10) days of delivery of any request by Landlord or any Master Lessor or Mortgagee, Tenant shall execute, acknowledge and deliver any instruments reasonably requested to effect and confirm the subordination of this Lease to any such Superior Lease and/or Mortgages or to effect and confirm that this Lease is superior thereto.

17.2 Attornment. If requested to do so, Tenant shall attorn to and recognize as Tenant's landlord under this Lease any Master Lessor or Mortgagee or foreclosure purchaser taking title to the Building by reason of the termination of any Superior Lease or the foreclosure of any Mortgage (such Master Lessor, Mortgagee or foreclosure purchaser shall herein be called a "Successor"), and Tenant shall, within ten (10) days of delivery of any request by the Successor, execute any documents reasonably requested by any such Successor to evidence the attornment described in this Section 17.2.

17.3 Exceptions. If Tenant becomes the direct tenant of a Successor pursuant to Section 17,1 or 17.2., and if the Successor is not under common ownership or control with the Person that constituted Landlord immediately prior to such Successor's becoming Tenant's landlord, then the Successor shall not be:

(a) liable for any act or omission of any prior landlord (including, without limitation, the then defaulting landlord), except to the extent such act or omission continues after the date that the Successor succeeds to Landlord's interest in this Lease, or

(b) subject to any defenses or offsets that Tenant has against any prior landlord (including, without limitation, the then defaulting landlord), or

(c) bound by any payment of Rent that Tenant has made to any prior landlord (including, without limitation, the then defaulting landlord) more than thirty (30) days in advance of the date that such payment is due, unless the Successor actually receives or approves such payment, or

(f) bound by any amendment or modification of this Lease made without the consent of the Successor, or

(g) liable for any security deposit or other money of Tenant held by a prior landlord except to the extent such sums are actually received by the Successor from such prior landlord.

17.4 Notice and Right to Cure. Tenant agrees to send by certified mail to any Mortgagee or Master Lessor identified in any written notice from Landlord to Tenant a copy of any notice of default sent by Tenant to Landlord, Landlord shall have 30 days to cure such default, or if it cannot be cured within 30 days, then such additional tune as is necessary to cure such default. If Landlord fails to cure such default within the required time period under this Lease, but the Mortgagee or Master Lessor begins to cure within ten (10) business days after such period and proceeds diligently to complete such cure, then the Mortgagee or Master Lessor shall have such additional time as is necessary to complete such cure, including any time necessary to obtain possession if possession is necessary to cure, and Tenant shall not begin to enforce its remedies so long as the cure is being diligently pursued.

18. ASSIGNMENT AND SUBLEASE.

18.1 In General. Tenant shall not, without the prior written consent of Landlord in each case, (i) make or allow any assignment or transfer, by operation of law or otherwise, of any part of Tenant's interest in this Lease, (ii) sublet any part of the Premises or modify an existing sublease, (iii) grant any security interest in Tenant's leasehold interest in the Premises or (iv) permit anyone other than Tenant and its employees to occupy any part of the Premises (collectively or individually, a 'Transfer"). Tenant shall remain primarily liable for all of its obligations under this Lease, notwithstanding any Transfer, whether or not permitted hereunder. No consent granted by Landlord shall be deemed to be a consent to any subsequent Transfer. Any Transfer made without Landlord's prior written consent shall be void. If Tenant shall assign this Lease or sublet the Premises in its entirety, any rights of Tenant to renew this Lease, extend the Term or lease additional space in the Project shall be extinguished thereby and shall not be transferred to the assignee or subtenant, all such rights being personal to the Tenant named herein.

18.2 Landlord's Consent. Unless Landlord exercises Landlord's right under Section 18.8 below to recapture the portion of the Premises proposed to be Transferred, Landlord shall not unreasonably withhold its consent to any proposed Transfer. It shall be reasonable for Landlord to withhold its consent to any Transfer if (i) an Event of Default or circumstances that would be an Event of Default with the passing of time, the giving of notice, or both then exist under this Lease, (ii) the proposed assignee, subtenant or other party acquiring an interest in this Lease or the Premises (in each case, a 'Transferee") is a tenant in the Project or an affiliate of such a tenant or a party that Landlord or any employee or agent of Landlord has identified as a prospective tenant in the Project, (iii) the financial responsibility, nature of business, and character of the proposed Transferee are not all satisfactory to Landlord (even though the same may be equal to or better than those of Tenant) in Landlord's reasonable judgment, (iv) in the reasonable judgment of Landlord the purpose for which the Transferee intends to use the Premises (or a portion thereof) is not in keeping with Landlord's standards for the Building or are in violation of the terms of this Lease or any other leases in the Project, (v) the proposed assignee or subtenant is a government entity, or (vi) the proposed Transfer is of less than the entire Premises or for less than the remaining Term of the Lease. The foregoing list shall not exclude any other reasonable basis for Landlord to withhold its consent.

18.3 Procedure; Information. Tenant shall notify Landlord of any proposed Transfer at least thirty (30) days prior to its proposed effective date. The notice shall include the name and address of the proposed Transferee, its corporate affiliates in the case of a corporation, its members in the case of a limited liability company, and its partners in a case of a partnership, an execution copy of the proposed assignment or sublease, and sufficient additional information to permit Landlord to determine the financial responsibility and character of the proposed Transferee and its owners. Tenant shall promptly provide to Landlord any other information that Landlord reasonably requests regarding any proposed Transfer.

18.4 Express Assumption Required. No Transfer of this Lease shall be effective unless the Transferee delivers to Landlord a fully executed assumption of Tenant's obligations under this Lease in form satisfactory to Landlord (which assumption may be incorporated into the instrument of assignment or sublease) and all other conditions to such Transfer provided herein have been satisfied.

18.5 Change of Management or Ownership. For the purposes of this Lease, a direct or indirect transfer of more than a fifty percent (50%) beneficial interest in Tenant or in any party directly or indirectly controlling Tenant ("controlling" meaning ownership of more than fifty (50%) percent of the voting equity interests in the party in question, measured by the proportionate voting rights appurtenant to such interests), whether such transfer occurs at one time or in a series of related transactions, and whether of stock, partnership interest or otherwise, is deemed an assignment of this Lease; provided, however, that this Section 18.5 shall not apply if Tenant is a corporation whose stock is traded on a recognized security exchange or over-the- counter market.

18.6 Excess Payments and Subtenant Payments. If Tenant shall assign this Lease or sublet any part of the Premises for consideration in excess of the pro-rata portion of Rent applicable to the space subject to the assignment or sublease, then Tenant shall pay to Landlord as Additional Rent 50% of any such excess immediately upon receipt. If an Event of Default

occurs, Landlord may require that all sublease payments be made directly to Landlord, in which event Landlord shall credit such payments received by Landlord against Tenant's obligation to pay Rent.

18.7 Landlord's Costs. Tenant shall pay to Landlord, within thirty (30) days after demand therefore, all reasonable out-of-pocket costs and expenses (including, without limitation, reasonable attorneys' fees and disbursements) incurred by Landlord in connection with any proposed Transfer for which Landlord's consent is required.

18.8 Recapture. Landlord may, by giving written notice to Tenant within thirty (30) days after receipt of Tenant's notice of intent to make a Transfer, terminate this Lease with respect to the space described in Tenant's notice, as of the effective date of the proposed Transfer, in which event all obligations under this Lease as to such space shall expire as of such date except as to any obligations that expressly survive any termination of this Lease. Tenant's right to assign the Lease or sublet all or any portion of the Premises is subject to Landlord's right to recapture the Premises under this Section 18,8.

18.9 Effect of Termination, The termination of this Lease shall, at Landlord's option, which may be exercised separately with respect to each sublease or subtenancy, either terminate such sublease or subtenancy or operate as an assignment thereof to Landlord.

19. CONVEYANCE BY LANDLORD. If Landlord shall at any time transfer its interest in the Project or this Lease, Landlord shall be released of any obligations occurring after such transfer, except the obligation to return to Tenant any security deposit not delivered to its transferee, and Tenant shall look solely to Landlord's successors for performance of such obligations. Tenant shall fully and completely attorn to and recognize each such successor as the successor Landlord hereunder. This Lease shall not otherwise be affected by any such transfer.

20. ESTOPPEL CERTIFICATE.

20.1 Duty to Provide, Tenant shall, within ten (10) business days of receiving a request from Landlord or any Master Lessor or Mortgagee, execute, acknowledge in recordable form, and deliver to the requesting party or its designee a certificate stating, subject to a specific statement of any applicable exceptions, that the Lease as amended to date is in rail force and effect, that the Tenant is paying Rent and other charges on a current basis, and that to the best of the knowledge of the Tenant, the Landlord has committed no uncured defaults and has no offsets or claims. The certifying party may also be required to state the date of commencement of payment of Rent, the Commencement Date, the Termination Date, the Base Rent, the current Operating Cost Share Rent and Tax Share Rent estimates, the status of any improvements required to be completed by Landlord, the amount of any security deposit, and such other matters as may be reasonably requested. It is intended that any such certificate delivered by Tenant may be relied upon by Landlord, any Master Lessor, Mortgagee, prospective mortgagee or prospective purchaser of the Project.

20.2 Tenant's Failure to Deliver. Tenant acknowledges that it may be difficult, if not impossible, for Landlord to sell or finance the Building without such an estoppel certificate from Tenant and that Landlord would not enter into this Lease without Tenant's agreement to provide

such an estoppel certificate. Tenant's failure to deliver any estoppel certificate in the time and manner provided herein shall constitute an Event of Default under Section 1.2. Kb). Tenant shall also pay any damages incurred by Landlord as a result of Tenant's failure (including costs or damages resulting from a lost sale or financing). Tenant's failure to timely execute and deliver such estoppel certificate will be conclusive upon Tenant that this lease is in full force and effect, without modification except as may be represented by Landlord, that there are no uncured defaults in Landlord's performance, and that not more than one month's Base Rent has been paid in advance,

21. SECURITY DEPOSIT. Tenant shall deposit with Landlord on the date of this Lease, security for the performance of all of its obligations in the amount set forth on the Schedule. If Tenant defaults under this Lease, Landlord may use any part of the Security Deposit to make any defaulted payment, to pay for Landlord's cure of any defaulted obligation, or to compensate Landlord for any loss or damage resulting from any default. To the extent any portion of the deposit is used, Tenant shall within five (5) days after demand from Landlord restore the deposit to its full amount. Landlord may keep the Security Deposit in its general funds and shall not be required to pay interest to Tenant on the deposit amount. If Tenant shall perform all of its obligations under this Lease and return the Premises to Landlord at the end of the Term, Landlord shall return all of the remaining Security Deposit to Tenant within sixty (60) days after the end of the Term. The Security Deposit shall not serve as an advance payment of Rent or a measure of Landlord's damages for any default under this Lease. If Landlord transfers its interest in the Project or this Lease, Landlord may transfer the Security Deposit to its transferee. Upon such transfer, Landlord shall have no further obligation to return the Security Deposit to Tenant, and Tenant's right to the return of the Security Deposit shall apply solely against Landlord's transferee.

22. FORCE MAJEURE. Landlord shall not be in default under this Lease to the extent Landlord is unable to perform any of its obligations on account of any strike or labor dispute, energy shortage, governmental pre-emption or prescription, national emergency, or any other cause of any kind beyond the reasonable control of Landlord ("Force Majeure").

23. NOTICES. All notices, consents, approvals and similar communications to be given by one party to the other under this Lease, shall be in writing and shall be delivered by certified or registered mail, return receipt requested, or by commercial courier or hand delivery to the following address:
