4.2           Payments of Taxes and Operating Expenses. In addition to Base Rent, Tenant shall reimburse Landlord for Real Estate Taxes and Operating Expenses for the Building as hereinafter set forth. It is hereby agreed that during each Lease Year of the Lease Term hereof, Tenant shall pay to Landlord Tenant’s Proportionate Share of the amount of increase in the Operating Expenses and Real Estate Taxes over Tenant’s Proportionate Share of the Base Real Estate Taxes and Base Operating Expenses. It is agreed that Tenant shall, during each calendar year in which the term of this Lease commences pay to Landlord an estimate of Tenant’s Proportionate Share of such increased Real Estate Taxes and Operating Expenses, if any, as hereinafter set forth. Beginning with the first calendar year following the year in which this Lease commenced, Tenant shall pay to Landlord each month on the first day of the month an amount equal to one-twelfth (1/12) of the increase, if any, in Tenant’s Proportionate Share of the Operating Expenses for the new calendar year as reasonably estimated by Landlord over Tenant’s Proportionate Share of the Base Real Estate Taxes and Operating Expenses, with an adjustment to be made between the parties at a later date as hereinafter provided. Furthermore, Landlord may from time to time but no more than three (3) times during any Lease Year furnish Tenant with notice of a re-estimation of the Real Estate Taxes and Operating Expenses and Tenant shall commence paying its re-estimated Proportionate Share on the first day of the month following receipt of said notice. As soon as practicable following the end of any calendar year, Landlord shall submit to Tenant a statement setting forth the exact amount of the increase, if any, in Tenant’s Proportionate Share of the Real Estate Taxes and Operating Expenses for the calendar year just completed over Tenant’s Proportionate Share of the Base Real Estate Taxes and Operating Expenses, and the difference, if any, between Tenant’s actual Proportionate Share of the Real Estate Taxes and Operating Expenses for the calendar year just completed and

6

the estimated amount of Tenant’s Proportionate Share of the Real Estate Taxes and Operating Expenses (which was paid in accordance with this subparagraph) for such year. Such statement shall also set forth the amount of the estimated Real Estate Taxes and Operating Expenses reimbursement for the new calendar year computed in accordance with the foregoing provisions. To the extent that Tenant’s Proportionate Share of the actual Real Estate Taxes and Operating Expenses for the period covered by such statement are higher than the estimated increases which Tenant previously paid during the calendar year just completed, Tenant shall pay to Landlord the difference in cash within thirty (30) days following receipt of said statement from Landlord. To the extent that Tenant’s Proportionate Share of the actual Real Estate Taxes and Operating Expenses for the period covered by the Statements are less than the estimated increases which Tenant previously paid during the calendar year just completed, Landlord may at its option either refund said amount in cash to Tenant or credit the difference against Tenant’s next accruing Base Rent or Additional Rent. In addition, with respect to the monthly reimbursement, until Tenant receives such statement, Tenant’s monthly reimbursement for the new calendar year shall continue to be paid at the then current rate, but Tenant shall commence payment to Landlord of the monthly installments of reimbursement on the basis of the statement beginning on the first day of the month following the month in which Tenant receives such statement.

Tenant’s obligation with respect to its proportionate share of the Real Estate Taxes and Operating Expenses shall survive the expiration or early termination of this Lease and Landlord shall have the right to retain the Security Deposit, or so much thereof as it deems necessary, to secure payment of Tenant’s Proportionate Share of the actual Real Estate Taxes and Operating Expenses for the portion of the final year of the Lease during which Tenant was obligated to pay such expenses. If Tenant occupies the Premises for less than a full calendar year during the first or last calendar years of the term hereof, Tenant’s Proportionate Share for such partial year shall be calculated by proportionately reducing the Base Real Estate Taxes and Operating Expenses to reflect the number of months in such year during which Tenant occupied the Premises (the “Adjusted Base Real Estate Taxes and Operating Expenses”). The Adjusted Base Real Estate Taxes and Operating Expenses shall then be compared with the actual Real Estate Taxes and Operating Expenses for said partial year to determine the amount, if any, of any increases in the actual Real Estate Taxes and Operating Expenses for such partial year over the Adjusted Base Real Estate Taxes and Operating Expenses. Tenant shall pay its Proportionate Share of any such increases within thirty (30) days following receipt of notice thereof.

Tenant shall have the right but not more than once per annum, at any time within one hundred twenty (120) days after a statement of actual Real Estate Taxes and Operating Expenses for a particular calendar year has been rendered by Landlord as provided herein, at Tenant’s sole cost and expense, to examine Landlord’s books and records during normal business hours, at Landlord’s office relating to the determination of such Real Estate Taxes and Operating Expenses. Unless Tenant objects to the statement herein within said one hundred twenty (120) days following receipt of Landlord’s statement, such statement and adjustment shall be deemed conclusive.

4.3           Gross Up of Operating Expenses. If at any time the Building is not fully occupied or Landlord is not supplying services to all rentable areas of the Building during an entire calendar year, then Landlord may adjust actual Operating Expenses to Landlord’s reasonable estimate of that amount, which would have been paid or incurred by Landlord as Operating Expenses had the Building been fully occupied or serviced, and the Operating Expenses as so adjusted shall be deemed to be the actual Operating Expenses for such calendar year, provided that in such case that a similar adjustment is also made to the Base Year Operating Expenses. If Landlord does not furnish during any applicable period any particular work or service (the cost of which, if performed by Landlord, would constitute an Operating Expense) to a tenant which has undertaken to perform such work or service in lieu of the performance thereof by Landlord, then Operating Expenses shall be deemed to be increased by an amount equal to the additional expense which would reasonably have been incurred during such period by Landlord if it had, at its cost, furnished such work or service to such tenant. The provisions of the preceding sentences will apply only to those Operating Expenses that either vary with occupancy or by reason of one or more tenants not receiving goods or services the cost of which constitutes all or part of such Operating Expenses.

7

4.4                                 Reimbursement Survives Termination. In the event of the termination of this Lease by expiration of the stated term or for any other cause or reason whatsoever prior to the determination of rental adjustment as hereinafter set forth, Tenant’s agreement to reimburse Landlord up to the time of termination shall survive termination of the Lease and Tenant shall pay any amount due to Landlord within fifteen (15) days after being billed therefor. In the event of the termination of this Lease by expiration of the stated term or for any other cause or reason whatsoever, except default by Tenant of any of the terms or provisions of this Lease, prior to the determination of rental adjustments as hereinabove set forth, Landlord’s agreement to refund any excess additional rental paid by Tenant up to the time of termination shall survive termination of the Lease and Landlord shall pay the amount due to Tenant within fifteen (15) days of Landlord’s determination of such amount. This covenant shall survive the expiration or termination of this Lease.

If the last year of the term of this Lease ends on any day other than the last day of December, any payment due to Landlord by reason of any increase in Real Estate Taxes and Operating Costs shall be prorated on the basis by which the number of days in such partial year bears to 365.

Any failure of Landlord to furnish Tenant with an estimate of its Proportionate Share of Real Estate Taxes and Operating Expenses or any statements as set forth in this Article 4 shall not act to relieve Tenant of its liability therefor; and with respect to any deficiencies, Tenant agrees to pay same within thirty (30) days of written demand from Landlord.

Landlord agrees to furnish to the Premises during regular business hours from 7:00 a.m. to 6:00 p.m. Mondays through Fridays and from 8:00 a.m. to 1:00 p.m. Saturdays, except for holidays as the same are determined by Landlord, and subject to the rules and regulations of the Building, heat and air conditioning for the use and occupancy of the Premises, passenger elevator service and freight elevator service, subject to scheduling by Landlord provided, however, that a passenger elevator shall always be available to Tenant.

Elevator service shall mean service either by non-attended automatic elevators or elevators with attendants at the option of Landlord. Landlord shall also furnish, at rates set from time to time as solely determined by Landlord, heating and air conditioning and such other items as are not provided for herein, provided Tenant gives Landlord not less than forty-eight (48) hours notice of Tenant’s needs for such additional heating or air conditioning.

Landlord shall also, at said times, maintain and keep lighted the common stairs, entries, and toilet rooms in the Building that would reasonably be subject to use by Tenant, its agents and employees during other than regular business hours. Landlord also has the right to charge Tenant for energy costs incurred because of Tenant’s above Building average usage or by reason of usage of the Premises or the Building during other than regular business hours.

5.2                                 Interruption of Standard Services. Tenant agrees that Landlord shall not be liable for failure to supply any heating, air conditioning, elevator, janitorial services, electric current, or any other service described in this Lease during any period when Landlord uses reasonable diligence to restore or to supply such services or electric current, it being further agreed that Landlord reserves the right to temporarily discontinue such services or any of them, or electric current at such times as may be necessary by reason of accident, unavailability of employees, repairs, alterations, or improvements, or whenever by reason of strikes, lockouts, riots, acts of God or any other happening or occurrence beyond the reasonable control of Landlord. If Landlord is unable to furnish such services or electric current, Landlord shall not be liable for damages to persons or property for any such discontinuance, nor shall such discontinuance in any way be construed as a constructive or actual eviction of Tenant or cause an abatement of rent or operate to release Tenant from any of Tenant’s obligations

Furthermore, due to Colorado Energy Code Design Requirements, Tenant hereby acknowledges that it may on certain days experience discomfort with the heating and air conditioning cycle, and Landlord shall have no responsibility or liability therefor.

If Landlord fails to provide any essential Building services specifically required to be provided by Landlord under the lease (i.e., water, electricity, sewer, elevator service, HVAC, restrooms, loss of life safety systems, failure of fire code compliance), and such interruption of service renders the Premises or any portion of the Premises untenantable for a period of five (5) consecutive business days following Landlord’s receipt of written notice from Tenant of such interruption of service, the Rent shall abate in proportion to the area of the Premises that is rendered untenantable. Such abatement period shall commence upon the expiration of said five (5) business day period. No such abatement shall be provided if such interruption of service is caused by the negligence or willful misconduct of Tenant, its agents, employees, contractors, subtenants, invitees or assignees or by an act of God, or by matters not within the control of Landlord (including without limitation the interruption of electrical service to the Building through no fault of Landlord). The Premises shall be considered untenantable if Tenant cannot use the Premises or portion thereof affected in the conduct of its normal business operations as a result of said interruption of service to the Premises. It is agreed and understood that Tenant shall not use or be entitled to use the Premises or portion thereof affected to conduct its normal business operations during any day for which Landlord is obligated to abate rent hereunder. The abatement herein provided shall he Tenant’s sole and exclusive remedy for interruption of service. Landlord agrees to use its reasonable efforts to restore such services as soon as possible. Tenant agrees to fully cooperate with Landlord in remedying any such interruption of essential Building services. The terms and conditions of this Section 5 shall not apply to situations contemplated under provisions of the Lease pertaining to condemnation, eminent domain, damage or destruction elsewhere described in the Lease.

Tenant shall directly pay for such telephone services, including the establishment and connection thereof, at the rates charged for such services by said authority or utility, and the failure of Tenant to obtain or to continue to receive such services for any reason whatsoever shall not relieve Tenant of any of its obligations under this Lease.

Tenant shall not, without the written consent of Landlord, not to be unreasonably withheld, use any apparatus or device which will in any way increase the amount of electricity or water which Landlord determines to be reasonable for use of the Premises as general office space, nor connect with electric current (except through existing electrical outlets in the Premises) or water pipes any apparatus or device for the purposes of using electric current, other energy or water. Landlord shall have the right to install one or more separately submetered electrical circuits to serve all of Tenant’s equipment, machinery or appliances which equipment, machinery or appliances requires electrical current supplied to the Premises for general office purposes as the same is determined by Landlord which costs of submetering shall be payable by Tenant to Landlord upon demand.

Tenant shall not sell, assign, encumber, mortgage or transfer this Lease or any interest therein, sublet or permit the occupancy or use by others of the Premises or any part thereof, or allow any transfer hereof of any lien upon Tenant’s interest by operation of law or otherwise (collectively, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Without limiting Landlord’s right to withhold such consent, the withholding of such consent may be based upon, but not limited to, the following:

(a)                                  In the reasonable judgment of Landlord, the subtenant or assignee (A) is of a character or engaged in a business, or proposes to use the Premises in a manner which is not in keeping with the standards of Landlord for the Building, or (B) has an unfavorable reputation or credit standing;

(b)                                 Either the area of the Premises to be sublet or the remaining area of the Premises is not regular in shape with appropriate means of ingress or egress suitable for normal renting purposes;

(c)                                  Tenant is in Default under this Lease;

(d)                                 [Intentionally Omitted];

(e)                                  The proposed sublessee or assignee is a person or entity with whom Landlord is then negotiating to lease space in the Building; or

(f)                                    The proposed assignment or sublease instrument does not have the substance or form which is reasonably acceptable to Landlord.

If Landlord consents to such sublet or assignment, such consent shall be expressly contingent upon Tenant’s payment to Landlord, as Rent, Landlord’s costs and expenses incurred in connection therewith, including, but not limited to, reasonable attorney’s fees and Landlord’s construction supervision fee, if applicable. Any Transfer which is not in compliance with the provisions of this Article shall, at the option of Landlord, be void and of no force or effect.

7.2                                 Notice to Landlord.  Tenant shall provide written notice of the proposed assignee, sublettee or transferee, as applicable, which notice shall provide Landlord with (i) the name and address of the proposed subtenant, assignee, pledgee, mortgagee or transferee, (ii) a reasonably detailed description of such person or entity’s business, (iii) detailed financial references for such person or entity, (iv) a true and complete copy of the proposed sublease, assignment, pledge, mortgage or other conveyance and all related documentation, and (v) such other information as Landlord may reasonably require.

7.3                                 Landlord’s Right of Recapture.  Tenant shall, by written notice in the form specified in the following sentence, advise Landlord of Tenant’s intention on a stated date (which shall not be less than thirty (30) days after date of Tenant’s notice) to sublet, assign, mortgage or otherwise Transfer any part or all of the Premises or its interest therein for the balance or any part of the Term, and, in such event, Landlord shall have the right, to be exercised by giving written notice to Tenant within ten (10) business days after receipt of Tenant’s notice, to recapture the space described in Tenant’s notice and such recapture notice shall, if given, cancel and terminate this Lease with respect to the space therein described as of the date stated in Tenant’s notice. If Tenant’s notice shall cover all of the space hereby demised, and Landlord shall elect to give the aforesaid recapture notice with respect thereto, then the Term shall expire and end on the date stated in Tenant’s notice as fully and completely as if that date had been herein definitely fixed for the expiration of the Term. If, however, this Lease is terminated pursuant to the foregoing with respect to less than the entire Premises, the Base Rent and Additional Rent then in effect shall be adjusted on the basis of the number of rentable square feet retained by

11

Tenant in proportion to the original Rentable Area of the Premises, and this Lease as so amended shall continue thereafter in full force and effect. In such event, Tenant shall pay the cost of erecting demising walls and public corridors and making other required modifications to physically separate the portion of the Premises remaining subject to this Lease from the rest of the Premises. If Landlord, upon receiving Tenant’s notice that it intends to sublet or assign any such space, shall not exercise its right to recapture the space described in Tenant’s notice, Landlord will, as hereinabove provided, determine whether to approve Tenant’s request to sublet or assign the space covered by its notice. Notwithstanding the above, Landlord’s right of recapture shall not apply to any entity Tenant desires to sublease to who may be a related or affiliated entity or entity with whom Tenant does mutual business activity.

7.4                                 Excess Rent. If Tenant individually, or as debtor or debtor in possession or if a trustee in bankruptcy acting on behalf of Tenant pursuant to the Bankruptcy Code, 11 U.S.C. 101 et seq., shall sublet or assign the Premises or any part thereof or assign any interest in this Lease at a rental rate (or additional consideration) in excess of the then current Monthly Base Rent and Adjustments per rentable square foot, fifty percent (50%) of said excess Rent (or additional consideration) shall be and become the property of Landlord and shall be paid to Landlord as it is received by Tenant, less Tenant’s reasonable brokerage (excluding commissions paid to brokers who are Tenant’s affiliates), legal and other expenses (“Tenant’s Costs”) incurred in connection with such assignment or, in the case of a sublease, less the monthly Proportionate Share of such Tenant’s Costs as determined by dividing such Tenant’s Costs by the number of months in the term of such sublease. If Tenant shall sublet the Premises or any part thereof, Tenant shall be responsible for all actions and neglect of the subtenant and its officers, partners, employees, agents, guests and invitees as if such subtenant and such persons were employees of Tenant. Nothing in this Section shall be construed to relieve Tenant from the obligation to obtain Landlord’s prior written consent to any proposed sublease.

7.5                                 Included Transfers. If Tenant is a partnership, a withdrawal or change, whether voluntary, involuntary or by operation of law or in one or more transactions, of partners owning a controlling interest in Tenant shall be deemed a voluntary assignment of this Lease and subject to the provisions of this Article. If Tenant is a corporation, any dissolution, merger, consolidation or other reorganization of Tenant, or the sale, transfer or redemption of a controlling interest of the capital stock of Tenant in one or more transactions, shall be deemed a voluntary assignment of this Lease and subject to the provisions of this Article. However, the preceding sentence shall not apply to corporations the stock of which is traded through a national or regional exchange or over-the-counter. Neither this Lease nor any interest therein nor any estate created thereby shall pass by operation of law or otherwise to any trustee, custodian or receiver in bankruptcy of Tenant or any assignee for the assignment of the benefit of creditors of Tenant.

7.6                                 No Waiver. The consent by Landlord to any Transfer shall not be construed as a waiver or release of Tenant from liability for the performance of all covenants and obligations to be performed by Tenant under this Lease, and Tenant shall remain liable therefor, nor shall the collection or acceptance of Rent from any assignee, subtenant or occupant constitute a waiver or release of Tenant from any of its obligations or liabilities under this Lease. Any consent given pursuant to this Article shall not he construed as relieving Tenant from the obligation of obtaining Landlord’s prior written consent to any subsequent assignment or subletting.

7.7                                 [Intentionally Omitted]

7.8                               Document Review. All documents utilized by Tenant to evidence any subletting or assignment for which Landlord’s consent has been requested, shall be subject to prior approval by Landlord or its attorney. Tenant shall pay on demand all of Landlord’s costs and expenses, including reasonable attorney’s fees, incurred in determining whether or not to consent to any requested subletting or assignment and for the review and approval of such documentation.

12

ARTICLE 8 - TRANSFER BY LANDLORD. In the event of a sale, conveyance, or assignment by Landlord of Landlord’s interest in the Building (other than a transfer for security purposes only), Landlord shall be relieved from and after the date specified in any such notice of transfer or assignment of all of Landlord’s obligations and liabilities accruing thereafter on the part of Landlord, and Tenant agrees to look only toward such assignee or transferee of Landlord’s interest, provided Landlord has transferred Tenant’s security deposit (if any).

ARTICLE 9 - USE OF PREMISES

Tenant and employees and all persons visiting or doing business with Tenant in the Premises shall be bound by and shall observe the reasonable Rules and Regulations as set forth in Exhibit D, attached hereto and made a part hereof, which may, at Landlord’s sole discretion, be promulgated, amended, or expanded from time to time in a non-discriminatory manor during the Lease term by Landlord relating to the Building and/or the Premises of which notice in writing shall be given to Tenant within thirty (30) days of such clause at which time they will become effective and all such rules and regulations as changed from time to time shall be deemed to be incorporated into and form a part of this Lease. Any default in the performance or observance of such rules and regulations shall be a default hereunder and Landlord shall have all remedies provided for in this Lease in the event of default by Tenant, Landlord however, shall not be responsible to Tenant for nonobservance by any other tenant or person of any tenant or person of any such rules and regulations. Landlord shall enforce such rules and regulations on a non-discriminatory basis.

9.3                                 Hazardous Substance. The term “Hazardous Substances,” as used in this lease shall mean pollutants, contaminates, toxic or hazardous wastes, or any other substances the use and/or the removal of which is required or the use of which is restricted, prohibited or penalized by any “Environmental Law,” which term shall mean any federal, state or local law, ordinance or other statute of a governmental or quasi-governmental authority relating to pollution or protection of the environment. Tenant hereby agrees that (i) no activity will be conducted on the Premises that will produce any Hazardous Substance, except for such activities that are part of the ordinary course of Tenant’s business activities (the “Permitted Activities”) provided said Permitted Activities are conducted in accordance with all Environmental Laws and have been approved in advance in writing by Landlord; Tenant shall be responsible for obtaining any required permits and paying any fees and providing any testing required by any governmental agency; (ii) the Premises will not be used in any manner for the storage of any Hazardous Substances except for the temporary storage of such materials that are used in the ordinary course of Tenant’s business (the “Permitted Materials”) provided such Permitted Materials are properly stored in a manner and location meeting all Environmental Laws and approved in advance in writing by Landlord; Tenant shall be responsible for obtaining any required permits and paying any fees and providing any testing required by any governmental agency; (iii) no portion of the Premises will be used as a landfill or a dump; (iv) Tenant will not install any underground tanks of any type; (v) Tenant will not allow any surface or subsurface conditions to exist or come into existence that constitute, or with the passage of time may constitute a public or private nuisance; (vi) Tenant will not permit any Hazardous Substances to be brought into the Premises, except for the Permitted Materials described below, and if so brought or found located thereon, the same shall be immediately removed, with proper disposal, and all required cleanup procedures shall be diligently undertaken pursuant to all Environmental Laws. Landlord or Landlord’s representative shall have the right but not the obligation to enter the Premises for the purpose of inspecting the storage, use and disposal of Permitted Materials to ensure compliance with all Environmental Laws. Should it be determined, in Landlord’s sole opinion, that said Permitted Materials are being improperly stored, used, or disposed of, then Tenant shall immediately take such corrective action as requested by Landlord. Should Tenant fail to take such

13

corrective action within 24 hours. Landlord shall have the right to perform such work and Tenant shall promptly reimburse Landlord for any and all costs associated with said work. If at any time during or after the term of the lease, the Premises is found to be so contaminated or subject to said conditions that were introduced by Tenant or its agents, employees or contractors, Tenant shall diligently institute proper and thorough cleanup procedures at Tenant’s sole cost, and Tenant agrees to indemnify and hold Landlord harmless from all claims, demand, actions, liabilities, costs, expenses, damages and obligations of any nature arising from or as a result of the use of the Premises by Tenant. The foregoing indemnification and the responsibilities of Tenant shall survive the termination or expiration of this Lease.

17

be employed in the Building by Landlord, its contractors or subcontractors. In addition to the above all contractors and subcontractors must meet Landlord’s specifications, as solely determined by Landlord, for minimum requirements for insurance, bonds, quality of work, experience and such other reasonably applicable factors. Tenant, shall provide Landlord upon request with financial assurances prior to the commencement of alterations, and promptly pay to Landlord’s or Tenant’s subcontractors, as the case may be, when due, the costs of all such work and of all materials, labor and services involved therein and of all decoration and all changes in the Building, its equipment or services necessitated thereby. Tenant covenants that Tenant will not suffer or permit during the Lease Term hereof any mechanics’ or other liens for work, labor, services or materials ordered by Tenant or for the cost of which Tenant may be in any obligated, to attach to the Premises or to the Building and that whenever and so often as any such liens shall attach or claims therefor shall be filed, Tenant shall, within twenty (20) days after Tenant has notice of the claim for lien, procure the discharge thereof by payment or by giving security or in such other manner as is or may be required or permitted by law or which shall otherwise satisfy Landlord. Tenant shall, at its own cost and expense, take out or cause to be taken out any additional insurance or bonds reasonably required by Landlord to protect Landlord’s and Tenant’s interest during the period of alteration.

At least five (5) days prior to the commencement of any work permitted to be done by persons requested by Tenant on the Premises, Tenant shall notify Landlord of the proposed work and the names and addresses of the persons supplying labor and materials for the proposed work so that Landlord may avail itself of the provisions of statutes such as Section 38-22-105(2) of the Colorado Revised Statutes (1973). During any such work on the Premises, Landlord, or its representatives, shall have the right to go upon and inspect the Premises at all reasonable times, and shall have the right to post and keep posted thereon notices such as those provided for by Section 38-22-105(2) C.R.S. (1973) or to take any further action which Landlord may deem to be proper for the protection of Landlord’s interest in the Premises.

ARTICLE 16 - SIGNS AND ADVERTISING

Tenant shall not install, paint, display, inscribe, place or affix any sign, picture, advertisements, notice, lettering or direction on any part of the Building or in the interior of the Premises or other portion of the Building. Landlord will prescribe a uniform pattern of identification signs for tenants to be placed on the outside corridor wall which is near the door leading into the Premises and other than such identification signs, Tenant shall not install, paint, display, inscribe, place or affix, or otherwise attach, any sign, picture, advertisement, notice, lettering or direction on the inside or outside of the Premises for exterior view without the written consent of Landlord.

Landlord will permit Tenant to place its signage in the lobby area of any full-floor that Tenant leases. Additionally, Landlord will permit Tenant to place its signage on the glass in the main lobby area of the Building (on a basis of joint identification with other tenants and occupants) after (i) Tenant is operating from an entire floor, and (ii) additional space on such glass area becomes available. All costs associated with the fabrication, installation, maintenance, removal and replacement of such signage shall be the sole responsibility of Tenant. Tenant shall remove such signage and repair any damage caused thereby, at its sole cost and

18

expense, upon the expiration or sooner termination of the Lease. The color, content, size and other specifications of any such signage shall be in accordance with the terms and conditions of the Lease, and shall be subject to Landlord’s prior approval, which approval shall not be unreasonably withheld, conditioned or delayed. Futher, Tenant shall ensure that all signage complies with any and all applicable local zoning codes and building regulations. Tenant’s rights for signage on the glass in the main lobby shall be subject and subordinate to any agreements between Landlord and other tenants, owners or occupants of the Building which are in effect as of the date of this Lease.

ARTICLE 17 - SUBORDINATION TO MORTGAGES AND DEEDS OF TRUST

17.1         This Lease and the rights of Tenant hereunder shall be and are hereby made subject and subordinate to the lien of any mortgages or deeds of trust now or hereafter existing against the Building and to all renewals, modifications, consolidations, replacements and extensions thereof and to all advances made, or hereafter to be made, upon the security thereof. Although such subordination shall be self-operating, Tenant, or its successors in interest, shall upon Landlord’s request, execute and deliver upon the demand of Landlord any and all instruments desired by Landlord, subordinating, in the manner reasonably requested by Landlord, this Lease to any such mortgage or deed of trust. If Tenant requests any modifications to such instrument(s), other than corrections, Tenant shall pay any reasonable fee required by the lender or other third party. Tenant will execute said instruments within ten (10) days after notice from Landlord demanding the execution thereof.

Should any mortgage or deed of trust affecting the Building be foreclosed, then:

(a)           The liability of the mortgagee, beneficiary or purchaser at such foreclosure sale shall exist only so long as such mortgagee, beneficiary or purchaser is the owner of the Building and such liability shall not continue or survive after further transfer of ownership; and

(b)           Tenant shall be deemed to have attorned, as Tenant under this Lease, to the purchaser at any foreclosure sale thereunder, and this Lease shall continue in full force and effect as a direct lease between and binding upon Tenant and such purchaser at any foreclosure sale.

As used in this Section “mortgagee” and “beneficiary” shall include successors and assigns of any such party, whether immediate or remote, the purchaser of any mortgage or deed of trust, whether at foreclosure or otherwise, and the successors, assigns and mortgagees and beneficiaries ofsuch purchaser, whether immediate or remote.

Landlord, at the written request of Tenant, agrees to request any mortgagee or beneficiary to enter into a non-disturbance agreement with Tenant, in a form satisfactory to such mortgagee or beneficiary, stating that Tenant’s right to the continued use and possession of the Premises shall be under the same terms and conditions as set forth in this Lease provided that at such time Tenant is not in default of its obligations herein. However, notwithstanding such request, Landlord makes no representations or warranties that such non-disturbance agreement will be entered into by any beneficiary or mortgagee.

ARTICLE 18 - ESTOPPEL CERTIFICATE

Tenant agrees that it will from time to time, upon request by Landlord, execute and deliver to Landlord within ten (10) days after demand therefor an estoppel certificate in Landlord’s form certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as so modified).

19

ARTICLE 19 - QUIET ENJOYMENT

Subject to the terms and provisions of this Lease, Landlord covenants and agrees that Tenant shall peaceably and quietly enjoy the Premises and Tenant’s rights hereunder during the term hereof, without hindrance by Landlord.

ARTICLE 20 - FIXTURES

Any or all installations, alterations, additions, partitions and fixtures other than Tenant’s trade fixtures in or upon the Premises, whether placed there by Tenant or Landlord, shall, immediately upon such placement, become the property of Landlord without compensation therefor to Tenant. Notwithstanding anything herein contained, Landlord shall be under no obligation to repair, maintain or insure such installations, alterations, additions, partitions and fixtures or anything in the nature of a leasehold improvement made or installed by or on behalf of Tenant. As a condition to Landlord’s consent to any improvement (other than the initial improvements made by Landlord pursuant to the Work Letter; provided, however, Tenant must remove all cabling upon the expiration or sooner termination of the Term, as more fully set forth in Section 6.4 above), Landlord may elect that any or all installations made or installed by or on behalf of Tenant be removed at the end of the Lease Term and, if Landlord so elects, it shall be Tenant’s obligation to restore the Premises to the conditions they were in previous to such alterations, installations, partitions and fixtures on or before the termination of this Lease. Such removal and restoration shall be at the sole expense of Tenant. Under no circumstances shall Landlord require that Tenant remove Building-standard improvements (such as paint, carpet and walls).

ARTICLE 21 - DAMAGE OR DESTRUCTION

21.1         Casualty. In the event that the Building should be totally destroyed by fire, tornado or other casualty, or should be so damaged that rebuilding or repairs cannot be completed within one hundred eighty (180) days after the date of such damage, Landlord may, at its option, terminate this Lease in which event the rent shall be abated during the unexpired portion of this Lease effective with the date of such damage, or Landlord may proceed to rebuild the Building and the Premises. In the event the Building should be damaged by fire, tornado or other casualty, but only to such extent that rebuilding or repairs in Landlord’s reasonable estimation can be completed within one hundred eighty (180) days after the date of such damage, or if the damage cannot be repaired within such time frame but Landlord does not elect to terminate this Lease, in either such event, Landlord shall, within sixty (60) days after the date of such damage commence to rebuild or repair the Building and shall proceed with reasonable diligence to restore the Building to substantially the same condition in which it was immediately prior to the happening of the casualty, except that Landlord shall not be required to rebuild, repair or replace any part of the partitions, fixtures and other improvements which may have been placed by Tenant or other tenants within the Building. In the event any mortgagee under a deed of trust, security agreement or mortgage on the Building should require that the insurance proceeds be used to retire the mortgage debt, Landlord shall have no obligation to rebuild and if Landlord so elects, this Lease shall terminate upon notice to Tenant. Unless otherwise provided in this Lease, any insurance which may be carried by Landlord or Tenant against loss or damage to the Building or to the Premises shall be for the sole benefit of the party carrying such insurance and under its sole control. Tenant may terminate this Lease if such damage occurs during the last year of the Term (as may be extended), such damage was not caused by Tenant, and in Landlord’s reasonable opinion such damage causes the Premises to be untenable for a period of in excess of ninety (90) days.

21.2         Casualty Caused by Tenant. If fire or other casualty causing injury to the Premises or other parts of the Building shall have been caused by the negligence or misconduct of Tenant, its agents, servants or employees, such injury may be repaired by Landlord at the expense of Tenant.

20

ARTICLE 22 - CONDEMNATION

22.1         Eminent Domain. If more than twenty percent (20%) of the Rentable Area of the Premises is taken by eminent domain, or by conveyance in lieu thereof, and if such taking interferes substantially with Tenant’s use of the Premises, then this Lease, at the option of either party evidenced by notice to the other given within thirty (30) days from such taking conveyance, shall forthwith cease and terminate entirely. In the event of such termination of this Lease, then rental shall be due and payable to the actual date of such termination. If less than twenty percent (20%) of the Rentable Area of the Premises is taken, or if more than twenty percent (20%) of the Premises is taken and neither party terminates this Lease, this Lease shall cease and terminate as to that portion of the Premises so taken as of the date of such taking, and the rental thereafter payable under this Lease shall be abated Proportionate from the date of such taking in an amount by which that portion of the Rentable Area of the Premises so taken shall bear to the Rentable Area of the Premises prior to such taking. If any part of the Building shall be taken by eminent domain, or by conveyance in lieu thereof, and if such taking substantially interferes with Landlord’s ownership or use of the Building, Landlord, at its option, may upon thirty (30) days’ notice to Tenant, terminate this Lease as of the date of such taking.

22.2         Damages. All compensation awarded for any taking (or the proceeds of private sale in lieu thereof) of the Premises or Building shall be the property of Landlord and Tenant hereby assigns its interest in any such award to Landlord; provided, however, Landlord shall have no interest in any award made to Tenant for the taking of Tenant’s fixtures and other personal property or moving expenses if a separate award for such items is made to Tenant.

22.3         Restoration. If both Landlord and Tenant elect not to terminate this Lease, Tenant shall remain in that portion of the Premises which shall not have been appropriated or taken as herein provided, and Landlord agrees, at Landlord’s sole cost and expense, to, as soon as reasonably possible, restore the remaining portion of the Premises to a complete unit of like quality and character as existed prior to such appropriation or taking.

ARTICLE 23 - LOSS AND DAMAGE AND DELAY

21

(c) loss or damage, however caused, to money, securities, negotiable instruments, papers or other valuables of Tenant, except to the extent caused by Landlord’s negligence or willful misconduct (subject to applicable limitations on liability and waivers of subrogation).

24.1         Default by Tenant. The following events shall be deemed to be events of default by Tenant under this Lease:

(a)           Tenant shall fail to pay any installment of rent or any other sum due to Landlord as herein provided and such failure shall continue for a period of five (5) days after notice.

(b)           Tenant shall fail to comply with any term, provision or covenant of this Lease, other than payment of rent or other sums due to Landlord, and shall not cure such failure within fifteen (15) days after written notice thereof to Tenant; provided, however, Tenant shall be granted such additional cure period (not to exceed sixty (60) days, provided that Landlord is not prejudiced by such extension and Tenant promptly commences and diligently pursues such cure to completion.

(c)           Tenant or any guarantor of Tenant’s obligations under this Lease shall die, cease to exist as a corporation or partnership or be otherwise dissolved or liquidated or become insolvent, or shall make a transfer in fraud of creditors, or shall make an assignment for the benefit of creditors.

(a)           Terminate this Lease, in which event Tenant shall immediately surrender the Premises to

22

Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying such Premises or any part thereof, by force if necessary, without being liable for prosecution of any claim of damages therefor.

(b)           Enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying such Premises or any part thereof, by force if necessary, without being liable for prosecution of any claim for damages therefor, and relet the Premises and receive the rent therefor.

(c)           Enter upon the Premises, by force if necessary, without being liable for prosecution of any claim for damages therefor, and do whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand for any expenses which Landlord may incur in thus effecting compliance with Tenant’s obligations under this Lease, and Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from such action, whether caused by the negligence of Landlord or otherwise.

(d)           Alter all locks and other security devices at the Premises without terminating this Lease.

In the event Landlord may elect to regain possession of the Premises by forcible detainer proceeding, Tenant hereby specifically waives, to the extent permitted by law, any statutory notice which may be required prior to such proceeding, and agrees that Landlord’s execution of this Lease is in part consideration for this waiver.

Exercise by Landlord of any one or more of the remedies hereunder granted or otherwise available shall not be deemed to be an acceptance of surrender of the Premises by Tenant, whether by agreement or by operation of law, it being understood that such surrender can be effected only by the written agreement of Landlord and Tenant. No such alteration of locks or other security devices and no removal or other exercise of dominion by Landlord over the property of Tenant or others at the Premises shall be deemed unauthorized or constitute a conversion, Tenant hereby consenting, after any event of default, to the aforesaid exercise of dominion over Tenant’s property within the Premises. All claims for damages by reason of such reentry and/or repossession and/or alteration of locks or other security devices are hereby waived, as all claims for damages by reason of any distress warrant, forcible detainer proceedings, sequestration proceedings or other legal process, to the extent permitted by law. Tenant agrees that any reentry by Landlord may be pursuant to judgment obtained in forcible detainer proceedings or other legal proceedings or without the necessity for any legal proceedings, as Landlord may elect, and Landlord shall not be liable in trespass or otherwise.

In the event Landlord elects to terminate the Lease by reason of an event of default then notwithstanding such termination, Tenant shall be liable for and shall pay to Landlord, at the address specified for notice to Landlord herein, the sum of all rental and other indebtedness accrued to date of such termination, plus, as damages, an amount equal to the total rental hereunder for the remaining portion of the Lease term (had such term not been terminated by Landlord prior to the date of expiration as stated herein).

In the event that Landlord elects to repossess the Premises without terminating the Lease, then Tenant shall be liable for and shall pay to Landlord at the address specified for notice to Landlord herein, all rental and other indebtedness accrued to the date of such repossession, plus rent required to paid by Tenant to Landlord during the remainder of the Lease term until the date of expiration of the term as stated herein diminished by any net sums thereafter received by Landlord through reletting the Premises during such period (after deducting expenses incurred by Landlord as provided below). In no event shall Tenant be entitled to any excess of any rental obtained by reletting over and above the rental herein reserved. Actions to collect amounts due by Tenant to Landlord under this subparagraph may be brought from time to time, on one or more occasions, without the necessity of Landlord’s waiting until expiration of the Lease term.

In the event of any default or breach by Tenant, or threatened or anticipatory breach or default, Tenant shall

23

also be liable and shall pay to Landlord, in addition to any sums provided to be paid above, broker’s fees incurred by Landlord in connection with reletting the whole or any part of the Premises; the costs of removing and storing Tenant’s or other occupants’ property; the costs of repairing, altering, remodeling, or otherwise putting the Premises into condition acceptable to a new tenant or tenants; and all reasonable expenses incurred by Landlord in enforcing or defending Landlord’s rights and/or remedies, including reasonable attorney’s fees whether suit was actually filed or not.

In the event of termination or repossession of the Premises for an event or default, Landlord shall not have any obligation to relet or attempt to relet the Premises or any portion thereof, or to collect rental after reletting; and in the event of reletting, Landlord may relet the whole or any portion of the Premises for any period to any Tenant and for any use or purpose.

24.3         Landlord’s Performance of Tenant’s Duties. If Tenant shall fail to make any payment or cure any default hereunder within the time herein permitted, Landlord, without being under any obligation to do so and without thereby waiving such default, may make such payment and/or remedy such other default for the account of Tenant (and enter the Premises for such purpose), and thereupon Tenant shall be obligated to, and hereby agrees to pay Landlord upon demand all costs. expenses and disbursements, including reasonable attorney’s fees incurred by Landlord in taking such remedial action.

24.4         No Prejudice. Landlord is entitled to accept, receive in cash or deposit any payment made by Tenant for any reason or purpose or in any amount whatsoever, and apply the same at Landlord’s option to any obligation of Tenant and the same shall not constitute payment of any amount owed except that to which Landlord has applied the same. No endorsement or statement on any check or letter of Tenant shall be deemed an accord and satisfaction or recognized for any purpose whatsoever. The acceptance of any such check or payment shall be without prejudice to Landlord’s rights to recover any and all amounts owed by Tenant hereunder and shall not be deemed to cure any other default nor prejudice Landlord’s rights to pursue any other available remedy.

24.5         Interest on Late Payments. Any rent (whether Base Rent or Additional Rent) or other amount due from Tenant to Landlord under this Lease not paid when due shall bear interest from the date due until the date paid at the rate of two percent (2%) per month or the maximum available per usury law, but the payment of such interest shall not excuse or cure any default by Tenant under this Lease. Failure to charge or collect such interest in connection with any one or more such late payments shall not constitute a waiver of Landlord’s right to charge and collect such interest in connection with any other or similar or like late payments.

24.6         Late Payment Charge. In addition to interest and other amounts, in the event any rent or other amounts owing hereunder are not paid within five (5) days after the due date, then Landlord and Tenant agree that Landlord will incur additional administrative expenses, the amount of which will be difficult if not impossible to determine. Notwithstanding the foregoing, Tenant shall be entitled to written notice and a five (5) day cure period on two (2) occasions during any twelve (12) month period, not to exceed a total of five (5) such notices, before such late fee is assessed. Accordingly, in addition to such required payment, Tenant shall pay to Landlord an additional one time late charge for any such late payment in the amount of five percent (5%) of the amount of such late payment.

24.7         Remedies Cumulative. All of Landlord’s rights and remedies under this Lease shall be cumulative with and in addition to any and all rights and remedies which Landlord may have at law or equity. Any specific remedy provided for in any provision of this Lease shall not preclude the concurrent or consecutive exercise of a remedy provided for in any other provision hereof.

24.8         Landlord’s Default. Landlord shall not be deemed in default hereunder unless Tenant shall have given Landlord written notice of such default specifying such default with particularity and Landlord shall thereupon have thirty (30) days in which to cure any default unless such default cannot reasonably be cured within such

24

period wherein Landlord shall not be in default if it commences to cure the default within the thirty (30) day period and diligently pursues completion of same. In the event of any default, Tenant agrees that its exclusive remedy shall be an action for damages.

24.9         Personal Property Lien. Policy Studies Inc. (the “Borrower”) has entered into a Credit and Security Agreement with Key Bank National Association (the “Lender”) under which the Lender holds a first priority security interest in all of the Borrower’s personal property of every kind and nature including without limitation all inventory, accounts, equipment, general intangibles, instruments, documents, and investment property of the Borrower, whether now owned or hereafter acquired, all together with all substitutions and replacements for and products and proceeds thereof (the “Collateral”). The interests of the Landlord under the lease, if any, in the personal property of the Borrower are subject to the Lender’s prior interest in the Collateral under the Credit Agreement. Landlord’s obligations to the Lender with respect to the Collateral on the Premises under the lease are not greater than the Landlord’s obligation to the Borrower with respect to the Collateral under the terms of the Lease. Under no circumstances shall the term “Collateral” be deemed to include any leasehold improvements, including, without limitation, light fixtures, floor coverings, plumbing, HVAC, and other similar items.

ARTICLE 25 - HOLDING OVER

Such holding over may be terminated by Landlord or Tenant upon fifteen (15) days’ notice. In the event that Tenant fails to surrender the Premises upon termination or expiration of this Lease or such month to month tenancy, then Tenant shall indemnify Landlord against loss or liability resulting from any delay of Tenant in not surrendering the Premises, including, but not limited to, any amounts required to be paid to third parties who were to have occupied the Premises and any attorney’s fees related thereto.

The undisputed portion of such sum shall be returned to Tenant within thirty (30) days following the expiration of the Lease Term and delivery of possession of the Premises to Landlord if, at such time, Tenant has fully performed all such terms, covenants and conditions. Prior to the time when Tenant is entitled to the return of the Security Deposit, Landlord shall be entitled to intermingle such deposit with its own funds and to use same for such purposes as Landlord may determine. Tenant shall not be entitled to any interest on the security deposit. In the event of default by Tenant in performing any of its obligations under this Lease, Landlord may, in addition to any other right or remedy available to Landlord hereunder, use, apply, or retain all or any part of this Security Deposit for the

25

payment of any unpaid rent or for any other amount which Landlord may he required to expend by reason of the default of Tenant. including any damages or deficiency in the reletting of the Premises or any attorney’s fees associated therewith, regardless of whether the accrual of such damages or deficiency occurs before or after an eviction.

(e)          Termination. Provided that Tenant is not then in default beyond any applicable notice and cure period and Tenant has not exercised the Extension Option as set forth in Section 4 below, Tenant shall have the right to terminate the lease of the Expansion Space on August 31, 2010, provided that Tenant has given written notice of termination on or before September 1, 2009, and paid a termination fee to Landlord on or before July 31, 2010, equal to the unamortized costs of brokerage commissions, allowances and other costs relating to the Expansion Space (based on a five year term) as reasonably determined by Landlord and relayed to Tenant in writing.

(g)         No Default. Tenant may exercise the Expansion Option, and an exercise thereof shall only be effective, provided that at the time of Tenant’s exercise of the Expansion Option and on the Expansion Commencement Date Tenant is not in default following any applicable notice and the expiration of any applicable cure period hereunder.

2.             One Time Right of Refusal.

(a)   Grant of Right of Refusal. PROVIDED THAT THE EXPANSIONS OPTION AS SET FORTH IN SECTION 1 ABOVE HAS LAPSED IS OF NO FURTHER FORCE OR EFFECT, and subject to the provisions as hereinafter set forth, Landlord hereby grants to Tenant a right of refusal (“Right of Refusal”) to lease from Landlord that space located comprised of either the entire fourteenth (14th) or the entire fifteenth (15th) floor of the Building or both (“Refusal Space”).

(b)   Third Party Offer; Exercise Notice. At any time prior to June 30, 2006 (or March 31, 2007, if AT&T does not vacate early), if Landlord desires to accept a bona fide offer from a third party (“Third Party Offer”) to lease the Refusal Space or a portion thereof, Landlord shall first give to Tenant notice that Landlord has received such Third Party Offer and describing the terms and conditions of such Third Party Offer (“Third Party Offer Notice”). Tenant may exercise the Right of Refusal by giving Landlord written notice (“Exercise Notice”) within five (5) business days after the date of the Third Party Offer Notice of Tenant’s desire to lease that portion of the Refusal Space set forth in the Third Party Offer. Hereinafter the term “Refusal Space” shall be and shall mean the Refusal Space or portion thereof set forth in the Third Party Offer.

(c)           Expansion Amendment. After receipt of the Exercise Notice, Landlord and Tenant shall enter into an amendment of the Lease “Expansion Amendment” acceptable to Landlord and Tenant. Such Expansion Amendment shall provide that from and after the applicable date on which the Refusal Space is leased by Tenant (“Expansion Commencement Date”), the Lease shall be deemed modified as follows.

(i)            Base Rent for the Refusal Space shall be as set forth in the Third Party Offer;

(ii)           Tenant’s Share applicable to the Refusal Space shall be a fraction, the numerator of which shall be the number of rentable square feet in the Refusal Space and the denominator of which shall be the number of rentable square feet in the Building (as both shall be reasonably determined by Landlord);

31

(iii)  The Base Year applicable to the Refusal Space shall be as set forth in the Third Party Offer;

(iv)  Tenant shall accept the Refusal Space in the time, condition and manner described in the Third Party Offer;

(v)   Tenant’s lease of the Refusal Space shall be for the term set forth in the Third Party Offer;

(vi)  Other applicable terms and conditions of the Third Party Offer shall modify the Lease; and

(vii)   For all purposes under the Lease, other than for the applicable calculations set forth above, the term “Premises” shall be deemed to include the Refusal Space.

(d)     Subordination. Tenant’s Right of Refusal shall be subordinate to any and all existing rights or interests conferred to AT&T for all or any portion of the Refusal Space, as contained in any lease, or otherwise, in effect on the effective date of this Lease, including, without limitation, (i) options or rights regarding renewal, extension or expansion and/or (ii) subleases.

(e)     Failure to Exercise. If Tenant does not exercise its Right of Refusal in the time and manner set forth herein, the Right of Refusal shall be deemed terminated and of no further force or effect.

(f)      No Default. Tenant may exercise the Right of Refusal, and an exercise thereof shall only be effective, provided that Tenant has never been in default of any term or condition of this Lease beyond any applicable notice or cure period.

(g)     Not Transferable. Tenant acknowledges and agrees that the Right of Refusal shall be deemed personal to Tenant and if Tenant subleases, assigns or otherwise transfers any interests hereunder to any person or entity prior to the exercise of the Right of Refusal, the Right of Refusal shall lapse and be forever waived.

3.             Tenant’s Continuing Right of Opportunity.

(a)           Opportunity Space. PROVIDED THAT THE EXPANSION OPTION AS SET FORTH IN SECTION 1 ABOVE AND THE RIGHT OF REFUSAL AS SET FORTH IN SECTION 2 ABOVE HAVE BOTH LAPSED AND ARE OF NO FURTHER FORCE OR EFFECT, then if at any time during the initial four (4) years of the Term (or five (5) years if Tenant exercises the Extension Option as set forth in Section 4 below) Landlord desires to actively market any space that is horizontally adjacent to the Premises, Landlord shall give Tenant written notice (“Opportunity Space Notice”) of such event. Such notice shall identify the location, configuration and size of the space (“Opportunity Space”), as well as the applicable business terms under which Landlord is willing to lease such space (such as duration, commencement date, concessions, base rent, and additional rent). Within five (5) business days after the date the Opportunity Space Notice is given to Tenant, the time of giving of such notice to be of the essence of this Section, Tenant shall give Landlord written notice (“Opportunity Acceptance Notice”) of its election to lease the entire Opportunity Space.

(b)           Amendment. After receipt of any such Opportunity Acceptance Notice, Landlord and Tenant shall enter into an amendment to this Lease acceptable to Landlord and Tenant to amend the Lease pursuant to the terms and conditions of the Opportunity Space Notice. Except as set forth in the Opportunity Space Notice, the terms and conditions of the Lease as they apply to the Premises shall govern Tenant’s lease of the Opportunity Space.

(c)           Failure to Exercise. In the event that Tenant fails to exercise its right as aforesaid within five (5) business days of the date the Opportunity Space Notice is given to Tenant or, in the event Tenant shall have exercised its right and Tenant shall not have executed an amendment of this Lease as aforesaid within five (5)

32

business days from the date the Tenant is given such an Amendment, Tenant shall be deemed to have waived its right under this Section with respect to the Opportunity Space for a period of one hundred eighty (180) days beginning on the expiration of the applicable five (5) business day period. Except for such waiver, Tenant’s rights under this Section are continuous and, therefore, if the lease in favor of a third party of the Opportunity Space expires or otherwise terminates, and Landlord desires to accept an Opportunity to lease such Opportunity Space after the expiration of the above-referenced one hundred eighty (180) day period, Landlord shall again give Tenant notice of its right to lease such Opportunity Space.

(d)           Subordination. Tenant’s right of opportunity granted hereunder shall be subordinate to any and all existing rights or interests conferred to other tenants for all or any portion of the Opportunity Space, as contained in any lease, or otherwise, in effect on the date of execution of this Lease including, without limitation, (i) options or rights regarding renewal, extension or expansion, (ii) subleases and (iii) assignments.

(e)           Not Transferable. Tenant acknowledges and agrees that any right of opportunity granted herein shall be deemed personal to Tenant and if Tenant subleases, assigns or otherwise transfers any interests under this Lease prior to the exercise of any right of opportunity granted under this Section, such right shall lapse and be of no further force or effect.

(f)            No Default. Tenant shall be deemed to have waived its rights under this Section in the event that Tenant is ever in default under the Lease beyond any applicable notice and grace period.

4.             Extension Option. Tenant shall have the right and option (“Extension Option”) to renew this Lease for one (1) additional and consecutive period of five (5) years under the same terms and conditions as stated in the Lease (each a “Extension Option”), with the exceptions that (a) no further renewal options shall exist and (b) monthly rental for such renewal term shall be based on the then prevailing market rental rate as determined by Landlord in good faith based on then recent lease renewals within the Building and taking into consideration Tenant’s use and financial strength, but in no event shall be less than the monthly rental in effect for the last month of the Term immediately prior to the renewal. Tenant may reject the extension option granted herein within ten (10) days following Tenant’s receipt of Landlord’s determination of the prevailing market rental. The Extension Option shall be exercisable by Tenant, if at all, only by timely delivery to Landlord of written notice of election on or before twelve (12) months prior to the expiration of the then current Lease Term, but no earlier than eighteen (18) months prior to the expiration of the then current Lease Term. The option herein granted shall be deemed to be personal to Tenant, and if Tenant subleases any portion of the Premises or otherwise assigns or transfers any interest thereof to another party, such option shall lapse. In the event that Tenant is in default of any term or condition of the Lease beyond any applicable notice and grace period, then there shall be no extension of this Lease as provided herein.

5.                Satellite Dish. Provided this Lease shall be in full force and effect and Tenant shall not be in default hereunder beyond any applicable grace period, Tenant may, at its sole cost and expense, install and operate during the Term, a small (not to exceed eighteen (18) inches in diameter) satellite dish (hereinafter the “Satellite Dish”) on the roof of the Building at a location to be designated by Landlord, and reasonably acceptable to Tenant (hereinafter the “Installation Area”). The installation of such Satellite Dish shall be subject to the following:

(a)           Tenant shall not install or operate the Satellite Dish until it receives prior written approval from Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. Without limitation to the generality of the preceding sentence, it shall not be unreasonable for Landlord to withhold approval if the installation or operation of the Satellite Dish may (i) damage the Building or roof membrane, (ii) limit or void the roof warranty, and/or (iii) not be in keeping with the aesthetics of the Building. Prior to commencing installation, Tenant shall provide Landlord with (1) detailed plans and specifications for the installation of the Satellite Dish, (2) copies of all required permits, licenses and authorizations, which Tenant will obtain at its own expense and which Tenant will maintain at all times during the operation of the Satellite Dish, and (iii) a

33

Certificate of Insurance evidencing insurance coverage as required by this Lease and any other insurance reasonably required by Landlord for the installation and operation of the Satellite Dish.

(b)           Tenant warrants and represents that (i) Tenant shall repair in a good and workmanlike manner any damage to the roof of the Building caused by the installation of the Satellite Dish, (ii) the maintenance of the Satellite Dish on the roof or the operation thereof shall not cause interference with any telecommunications, mechanical or other systems either located at or servicing the Building (whether belonging to or utilized by Landlord or any other tenant or occupant of the Building) or located at or servicing any building, premises or location in the vicinity of the Building limited however to that permissible under applicable F.C.C. regulations to the extent that such regulations apply, (iii) the installation, existence, maintenance and operation of the Satellite Dish shall not constitute a violation of any applicable laws, ordinances, rules, orders, regulations, etc. of any Federal, State, county and municipal authorities having jurisdiction thereover.

(c)           The installation of the Satellite Dish shall be made subject to and in accordance with all of the provisions of this Lease. The contractors performing the installation of the Satellite Dish and/or performing any work on or to the roof of the Building shall be approved or designated by Landlord prior to the commencement of any work.

(d)           Tenant covenants and agrees that the installation, operation and removal of the Satellite Dish will be at its sole risk. Tenant agrees to indemnify and defend Landlord against all claims, actions, damages, liabilities and expenses including reasonable attorney’s fees and disbursements in connection with the loss of life, personal injury, damage to property or business or any other loss or injury or as a result of any litigation arising out of the installation, operation or removal of the Satellite Dish.

(e)           Landlord, at its sole option, may require Tenant, at any time prior to the Expiration Date, to terminate the operation of the Satellite Dish if it is causing physical damage to the structural exterior of the Building, interfering with any other service provided to other tenants in the Building, interfering with any other tenant’s business, in excess of that permissible under F.C.C. regulations to the extent that such regulations apply and such regulations shall not require such tenants or those providing such services to correct such interference. Notwithstanding the foregoing, if Tenant can correct the damage or disturbance caused by the Satellite Dish to Landlord’s reasonable satisfaction, Tenant may restore its operation. If the Satellite Dish is not corrected and restored to operation within thirty (30) days, Landlord, at its sole option, may require that Tenant remove the Satellite Dish at its own expense.

(f)            At the expiration or sooner termination of this Lease, or upon termination of the operation of the Satellite Dish, or revocation of any license issued, Tenant shall remove the Satellite Dish (and all associated wiring and other appurtenances) from the Building and repair and damage caused thereby, at Tenant’s sole cost and expense. Tenant shall leave the Installation Area in good order and repair. If Tenant does not remove the Satellite Dish when so required, Tenant hereby authorizes Landlord to remove and dispose of the Satellite Dish and to charge Tenant for all reasonable costs and expenses incurred.

6.             Conflict. In the event of any express conflict or inconsistency between the terms of this Rider and the terms of the Lease, the terms of this Rider shall control and govern.

Tenant shall be allowed to occupy, use, work in or otherwise enter the Expansion Premises following the Date of Substantial Completion as set forth in the Work Letter, attached hereto as Exhibit B and incorporated herein by this reference.
