In addition thereto, Tenant shall have the right to use, on a non-exclusive basis, and in common with the other tenants of the Building, if any, the Common Areas of the Building (as that term is defined in Section 6.2.4 hereof). The Premises and the Building shall be measured in accordance with BOMA standards (ANSI Z65.1- 1996), utilizing the “Gross Building Area” computation. At Tenant’s election, the Rentable Area of the Building as set forth in Section 1.1.3 shall be subject to confirmation before the Rent Commencement Date by Tenant’s architect, at Tenant’s sole cost. In the event the Rentable Area of the Building figure determined by Tenant’s architect differs by no more than 0.5% (higher or lower) from the Rentable Area of the Building set forth in Section 1.1.3 , then the Rentable Area of the Building set forth in Section 1.1.3 shall be controlling.

If such independent architect determines that the rentable area differs by no more than 0.5% from the Rentable Area of the Building set forth in Section 1.1.3, then the fees of such independent architect shall be borne by Tenant, otherwise such fees shall be borne by Landlord. Promptly after determination of the Rentable Area of the Building in accordance with this Section 2, Landlord and Tenant shall execute an amendment to this Lease confirming such determination and with a proportionate adjustment to Annual Base Rent, additional rent and any prior payments which have been made by Tenant. In no event shall Tenant be required to pay Annual Base Rent based on more than 157,514 rentable square feet regardless of the actual measurement of the rentable square footage of the Premises. Landlord shall have no right to remeasure the Premises during the Term. In the event Tenant does not elect to verify the Rentable Area of the Building pursuant to this Section 2, then the Rentable Area of the Building shall be as set forth in Section 1.1.3.

3. Term.

3.1 Commencement Date and Term. All of the provisions of this Lease shall be in full force and effect from and after the Effective Date. As used in this Lease, the term “Commencement Date”, as advanced or postponed pursuant to the terms hereof, shall be defined as the date of Delivery of Possession of Landlord Items (as defined in Section 35) and, subject to Section 35.1 hereof, the term “Rent Commencement Date” shall be the date which is one hundred fifty (150) days following that date of Delivery of Possession of Landlord’s Items (as defined in Section 35). Notwithstanding the foregoing to the contrary, if Tenant elects for Landlord to construct the Tenant’s Work pursuant to the terms of Section 35 below, the Commencement Date and the Rent Commencement Date shall be the date of Delivery of Possession of the Premises with Landlord’s Work substantially completed. The first Lease Year shall commence on the Commencement Date and shall end on the date which is last day of the calendar month which is twelve (12) full months after the Rent Commencement Date. Within fifteen (15) days after receipt of a written request from Landlord, Tenant shall execute and deliver the Commencement Date Agreement in substantially the form attached hereto as Exhibit “F”.

3.2 Option to Extend Lease Term. Provided Tenant is not in default of any term, covenant or condition of this Lease beyond any applicable notice and cure period, Tenant shall have the option to extend the Initial Term of this Lease for the entire Premises for three (3) additional periods of five (5) years each (the “Renewal Term”) to commence immediately upon the expiration of the Initial Term, the First Renewal Term and the Second Renewal Term, as applicable.

Tenant’s rental of the Premises during the First Renewal Term, the Second Renewal Term and the Third Renewal Term, as applicable, shall be upon the same terms, covenants and conditions contained in this Lease, except that Tenant shall pay to Landlord as Annual Base Rent that amount equal to the “Prevailing Market Rate” for the Premises for the First Renewal Term, the Second Renewal Term and the Third Renewal Term, as applicable, as hereinafter defined (including annual adjustments). For purposes of this Section 3.2, the term “Prevailing Market Rate” shall mean the then prevailing market rate being charged for renewals of comparable space in comparable office buildings within a ten (10) mile radius of the Premises, with consideration given for all factors appropriately considered in determining fair market economics of a similar transaction, including, but not limited to, construction allowances, commissions (or lack thereof), free rent, the creditworthiness of Tenant and other concessions or premiums, costs being saved and downtime for vacancy. In order to exercise its option granted herein, Tenant shall notify Landlord in writing of its intent to renew not less than three hundred sixty-five (365) days prior to the expiration of the Initial Term, the First Renewal Term or the Second Renewal Term, as applicable. Within thirty (30) days following the exercise by Tenant of its option to extend the Lease for the First Renewal Term, the Second Renewal Term and the Third Renewal Term, as applicable, Landlord shall notify Tenant in writing of its determination of the Prevailing Market Rate for the First Renewal Term, the Second Renewal Term and the Third Renewal Term, as applicable, as reasonably determined by Landlord (“Landlord’s Notice”). Within ten (10) business days after receipt of Landlord’s Notice, Tenant shall notify Landlord in writing of Tenant’s acceptance or rejection of such rate. If Tenant accepts the proposed Prevailing Market Rate by written notice to Landlord, Landlord and Tenant shall enter into an amendment to this Lease acknowledging such renewal and setting forth any terms at variance with the terms of this Lease. If, within the ten (10) day period, Tenant does not accept the proposed Prevailing Market Rate as determined by Landlord for the First Renewal Term, the Second Renewal Term and the Third Renewal Term, as applicable, then within twenty (20) days thereafter, Landlord and Tenant shall meet at a mutually acceptable time and place and shall use their reasonable efforts to agree upon the Prevailing Market Rate. If Landlord and Tenant shall fail to agree upon such Prevailing Market Rate for either the First Renewal Term, the Second Renewal Term or the Third Renewal Term, within the twenty (20) day period, Landlord and Tenant shall each appoint an independent commercial leasing broker licensed in the Maryland area within the next ten (10) days (the “Brokers”). Such Brokers shall deliver their respective estimates of the Prevailing Market Rate within ten (10) days after being appointed. If the estimates of the Prevailing Market Rate as quoted by the Brokers are within ten percent (10%) of each other, the Prevailing Market Rate shall be deemed to be the average of the estimates presented by the Brokers. If the estimates of the Prevailing Market Rate as quoted by the Brokers differ by more than ten percent (10%), then Landlord and Tenant shall jointly appoint a third independent commercial leasing broker licensed in the Maryland area within ten (10) days after the receipt of the initial brokers’ estimates (the “Third Broker”) who shall deliver its estimate of the Prevailing Market Rate within ten (10) days after being appointed and such estimate shall be deemed to be the Prevailing Market Rate. Tenant shall have the right to notify Landlord within ten (10) business days after receipt of the estimate of the Prevailing Market Rate (whether as resulting from the average of the Brokers or from the Third Broker, as applicable), that it rejects such Prevailing Market Rate and in such event, Tenant’s option to extend the Lease for the First Renewal Term, the Second Renewal Term or the Third Renewal Term, as applicable, shall be void and inoperable. If Tenant fails to exercise its right to reject the Prevailing Market Rate, then Landlord and Tenant shall enter into an amendment to this Lease acknowledging such renewal and setting forth any terms at variance with the terms of this Lease. Landlord and Tenant shall each pay the fee of the broker designated by them originally and shall split the fees of the Third Broker. If Tenant shall fail to deliver the requisite notice exercising its option to extend by the date prescribed above, then Tenant’s option to extend the Term for the First Renewal Term, the Second Renewal Term and the Third Renewal Term, as applicable, shall be void and inoperable. The Second Renewal Term and the Third Renewal Term shall terminate if Tenant does not elect to renew the Lease for the First Renewal Term. The Third Renewal Term shall terminate if Tenant does not elect to renew the Lease for the Second Renewal Term.

3.3 Definition of “Term”. As used herein, the word “Term” shall refer to the Initial Term the First Renewal Term, the Second Renewal Term and the Third Renewal Term, if applicable.

4. Security Deposit and Advance Rent.

4.1 Security Deposit. Simultaneously with the execution of this Lease, Tenant shall not be required to pay a Security Deposit in accordance with the terms of this Lease. However, if prior to the Rent Commencement Date, Tenant’s credit rating falls below a “BB-” as determined by Standard & Poor’s credit rating agency or ▇▇▇▇▇’▇ credit rating agency, Tenant shall pay to Landlord a Security Deposit in the amount of $1,998,307.50 by Letter of Credit (as further described below) as security for the performance by Tenant of all obligations imposed on Tenant hereunder. Tenant shall deliver to Landlord a statement of its credit rating on each January 15, April 15, July 15, and October 15^th occurring after the Effective Date and prior to the Rent Commencement Date; provided, however, that the provisions of the immediately proceeding sentence shall be effective at anytime prior to the Rent Commencement Date and shall not be limited to the reporting periods aforementioned. Tenant shall deliver the Letter of Credit within fifteen (15) days after written request from Landlord. Failure to deliver such Letter of Credit shall be an automatic Event of Default under the terms of the Lease, without further notice or cure periods afforded to Tenant.

In such event, Tenant shall deliver to Landlord an unconditional and irrevocable Letter of Credit issued by and drawable upon Comerica Bank in San Diego, California or another banking institution reasonably approved by Landlord in the amount of $1,998,307.50 to be held by Landlord as a guaranty for the payment and performance by Tenant of all covenants and obligations of Tenant as set forth in this Lease. The Letter of Credit shall contain terms whereby it can be drawn on by Landlord by sending the original Letter of Credit by overnight delivery, in the case of an institution which is not located in the Baltimore-Washington metropolitan area or on sight if located in the Baltimore-Washington metropolitan area on any date during the Term of this Lease on which issuer shall receive from Landlord a certification signed by Landlord stating that there is a Event of Default by Tenant under the terms of this Lease. Landlord shall have the right to make such certification immediately upon any Event of Default by Tenant hereunder (as defined in Section 21 hereof) and to apply said sum against all amounts then due and owing by Tenant hereunder and/or against sums required to be and actually expended by Landlord hereunder to correct existing defaults by Tenant. The Letter of Credit shall also provide that Landlord shall have the right to draw upon the Letter of Credit, in full or in part. Any balance left of the sum received from drawing on the Letter of Credit, after the correction of defaults by Tenant and/or the payment of amounts due by Tenant, shall be credited against the next Rent payment(s) due to Landlord. In the event Landlord shall draw on the Letter of Credit provided by Tenant, all as set forth herein, Tenant shall replace same no later than thirty (30) days after the date of such drawing, and if same is not replaced, it shall constitute an Event of Default under the terms of this Lease and Landlord shall have the benefit of all remedies permitted pursuant to the terms of this Lease and the laws of the State of Maryland.

Subject to the provisions of Section 4.1.1 below, Tenant acknowledges and agrees that it shall keep the Letter of Credit in full force and effect throughout the Term of this Lease. In the event the term of the Letter of Credit is not coterminous with the Term of this Lease, then not more than forty-five (45) days prior to any expiration date of the Letter of Credit, Tenant shall provide Landlord with the appropriate documentation that said Letter of Credit has been extended and provide Landlord with the new expiration date of same. Should Tenant fail to provide Landlord with such documentation on or before the expiration date of the Letter of Credit, Landlord shall have the right to draw on the entire amount of said Letter of Credit and hold it without interest for the benefit of Landlord as security for the faithful performance of the Lease until the Letter of Credit is reinstated or the Term of the Lease expires. If the Letter of Credit is not reinstated, the amount drawn by Landlord shall be returned to Tenant, less all costs incurred by Landlord in correcting or satisfying any Event of Default under this Lease within thirty (30) days after the expiration or earlier termination of the Term.

No right or remedy available to Landlord as provided in this Section 4.1 shall preclude or extinguish any other right or remedy to which Landlord may be entitled.

Notwithstanding the foregoing, if the Letter of Credit is required and Tenant then receives a rating of “BB” or higher by ▇▇▇▇▇’▇ for twelve (12) consecutive months, then Landlord shall return the Letter of Credit to Tenant and Tenant shall have no further obligation to pay a Security Deposit during the Term.

4.1.1 Transfer. Upon a sale of the Land and/or the Building or a leasing of the Building, or any financing of Landlord’s interest therein, Landlord shall have the right to transfer any cash Security Deposit or the Letter of Credit, as applicable, to the vendee, lessee or lender, provided such vendee, lessee or lender assumes Landlord’s obligations hereunder with respect to the cash Security Deposit or the Letter of Credit, as applicable. With respect to the Letter of Credit, within ten (10) business days after notice of such sale, leasing or financing, Landlord (with Tenant’s cooperation), at its sole cost, shall arrange for the transfer (by amendment) of the Letter of Credit to the new landlord or the lender, or have the Letter of Credit reissued in the name of the new landlord or the lender. To the extent so transferred, Tenant shall look solely to the new landlord or lender for the return of such cash Security Deposit or Letter of Credit and the provisions hereof shall apply to every transfer or assignment made of the Security Deposit to a new landlord.

4.1.2 Reduction.

(a) Provided no uncured Event of Default shall then exist, then on the first day of each Lease Year, commencing with the first day of the sixth (6^th) Lease Year, and continuing annually thereafter on the first day of each subsequent Lease Year in which Tenant qualifies for reduction (each such anniversary date, a “Reduction Date”), Tenant shall have the right to reduce the Security Deposit (a “Reduction”) to the amount set forth in the following schedule (the “Reduction Schedule”):

Reduction Date Amount

First Day of Lease Year #6 $1,665,256.25

First Day of Lease Year #7 $1,332,205.00

First Day of Lease Year #8 $ 999,153.75

First Day of Lease Year #9 $ 666,102.50

First Day of Lease Year #10 $ 333,051.25

(b) Provided Tenant qualifies as of any such Reduction Date, such Reduction shall be effectuated by Tenant’s delivery of either (i) a replacement letter of credit for the applicable lesser amount, which replacement letter of credit may (A) include an endorsement that provides that such replacement Letter of Credit shall be effective only upon Landlord’s return of the Letter of Credit being replaced or Landlord’s written consent to cancellation of the letter of credit being replaced, or (B) be delivered pursuant to an escrow arrangement otherwise reasonably approved by Landlord and Tenant, or (ii) at least ten (10) business days prior to the effective date of such Reduction, a written amendment to the Letter of Credit which has the effect of reducing the amount of the Letter of Credit to the lesser amount determined pursuant to this Section as of the applicable Reduction Date.

(c) If Tenant does not qualify for a Reduction as of any applicable Reduction Date, but Tenant subsequently does qualify for such Reduction as of a later Reduction Date, then Tenant shall be permitted to “catch up” all prior foregone Reductions as of the applicable Reduction Date. (For example, if Tenant had never previously qualified for a Reduction, but did so effective as of the Reduction Date coinciding with the first day of Lease Year #8, then the Security Deposit would be reduced from $1,998,307.50 to $999,153.75 as of such Reduction Date.)

4.2 Advance Rent. Upon execution of this Lease, Tenant shall pay Landlord the Advance Rent to be held as advance rent and security and which Landlord shall be entitled to retain, without limitation of other remedies, for any defaults of this Lease by Tenant occurring prior to the commencement of the Term. If no such defaults occur, the Advance Rent shall be applied by Landlord against first installments of Annual Base Rent payable by Tenant hereunder.

5. Use. Tenant covenants that it shall use and occupy the Premises during the Term of this Lease solely for general office purposes and uses incidental and ancillary thereto that are consistent with the operation of a Class A office building which uses may include, without limitation, data center, SCIF, training, employee/building invitee cafeteria/in-house food service, operations center, coffee and vending uses, Tenant company store, deli, light assembly for modification and testing of computers and related equipment, child care for employees, exercise facility and conference center, all in accordance with applicable zoning regulations.

6. Rent.

6.1 Annual Base Rent. As rent for the Premises during each year of the Term, commencing on the Rent Commencement Date, Tenant shall pay to Landlord an Annual Base Rent, in equal monthly installments, in advance on the first day of each calendar month during the Term, and without deduction, setoff or demand in accordance with the schedule set forth in Section 1.1.6 above. In addition, if the Rent Commencement Date occurs on a day other than the first day of a calendar month, Tenant shall pay to Landlord upon the Rent Commencement Date, a sum equaling that percentage of the monthly rent installment which equals the percentage of such calendar month falling after the Rent Commencement Date.

Notwithstanding the foregoing, Tenant shall have the right to ▇▇▇▇▇ a portion of the Annual Base Rent up to a maximum amount of either (i) $333,051.25 per month over the first three (3) months of the Term, computed as ($25.50 x 156,730)/12, or (ii)$166,525.63 per month over the first six (6) months of the Term, computed as [($25.50 x 156,730)/12] divided by 2. Tenant shall notify Landlord in writing on or before January 1, 2004, of the amount of Annual Base Rent, if any, which Tenant desires to ▇▇▇▇▇ and over what period of time. If Tenant fails to notify Landlord of its election to ▇▇▇▇▇ Annual Base Rent on or before January 1, 2004, Tenant shall be deemed to have waived its right to ▇▇▇▇▇ Annual Base Rent. If Tenant elects option (i), the Annual Base Rent for the 117 months remaining in the Initial Term shall be increased monthly by an amount equal to the quotient of the amount abated divided by 117 months; and if Tenant elects option (ii), the Annual Base Rent for the 114 months remaining in the Initial Term shall be increased monthly by an amount equal to the quotient of the amount abated divided by 114 months. By way of example, but without limitation, if Tenant elects to ▇▇▇▇▇ $333,051.25 per monthover the first three (3) months of the Initial Term, Annual Base Rent shall increase monthly commencing on the 4^th month and through the balance of the Initial Term in an amount equal to $2,846.59, computed as $333,051.25 divided by 117. If Tenant elects to ▇▇▇▇▇ Annual Base Rent pursuant hereto, (i) within fifteen (15) days after request from Landlord, the parties shall enter into an amendment to the Lease which sets forth the revised schedule of Annual Base Rent, and (ii) in no event shall Tenant’s obligation to pay for electrical service during such abatement period be abated in any regard.

6.2 Definitions. For the purposes hereof, the following definitions shall apply:

6.3 Rent Adjustments for Taxes.

6.3.1 On or before March 31 of each Lease Year, Landlord shall total the Taxes and shall allocate such Taxes to the Rentable Area of the Building in the following manner: Taxes for the foregoing tax year shall be totaled and such total shall be divided by the total rentable square feet in the Building thereby deriving the “Cost of Taxes Per Square Foot” of rentable area. Notwithstanding the foregoing, if Taxes are not fully assessed against the Property during the Base Year for Taxes, the Base Year for Taxes shall be deemed to be the full assessed value of the Taxes for a twelve (12) month period. Notwithstanding anything herein to the contrary, in no event shall Tenant be required to pay any additional rent for Taxes for the first twelve (12) months after the Building has been fully assessed.

6.3.2 In the event that the Cost of Taxes Per Square Foot assessed for any calendar year after calendar year 2005 which is wholly or partly within the Term are greater than the Base Year Taxes, Tenant shall pay to Landlord, as additional rent at the time such Taxes are due and payable, the amount of such excess times the number of Rentable Area of the Premises. Any additional rent due Landlord under this Section shall be due and payable within thirty (30) days after Landlord shall have submitted a written statement to Tenant showing the amount due, together with reasonably adequate documentation sufficient to support the amount requested to be paid pursuant to the invoice after Tenant fully occupies the Building. For Tenant's obligation for such additional rent at the end of the Lease, see Section 6.5. No later than fifteen (15) days prior to the start of each calendar year after the Base Year Taxes are determined, Landlord will deliver to Tenant its reasonable estimate of such additional rent with respect to Taxes, and require Tenant to pay each month, in advance, during such year 1/12 of such amount, at the time of payment of monthly installments of Base Rent. Tenant shall have the right to examine, at Tenant's sole expense, Landlord's records with respect to any such increases in rent; provided, however, that unless Tenant shall have given Landlord written notice of exception to any such statement within thirty (30) days after delivery thereof, the same shall be conclusive and binding on Tenant for the applicable year, subject to Tenant’s audit rights. If Landlord has not delivered the estimate of Taxes to Tenant by the first day of January of the applicable calendar year, Tenant will continue paying Tenant’s Share of Taxes based on the Tax estimate for the previous calendar year until the new estimate of Taxes is delivered. No credit shall be given to Tenant if the Cost of Taxes Per Square Foot are less than the Base Year Taxes.

6.3.3 Landlord’s Right to Contest Property Taxes. Landlord is not obligated to but may contest the amount or validity, in whole or in part, of any Taxes. Landlord’s contest will be at Landlord’s sole cost and expense, except that if Taxes are reduced (or if a proposed increase is avoided or reduced) because of Landlord’s contest, Landlord may include in its computation of Taxes the costs and expenses Landlord incurred in connection with the contest, including, but not limited to, reasonable attorney’s fees, up to the amount of any Tax reduction Landlord realized from the contest or any Tax increase avoided or reduced in connection with the contest, as the case may be.

6.3.4 Tenant’s Right to Request Landlord to Obtain a Reduction in Assessments. Tenant may request in writing that Landlord, from time to time, but no more often than once every two (2) years during the Term, endeavor to obtain a reduction in the assessed valuation of the Building for the purpose of reducing Taxes. In such event, Landlord shall use commercially reasonable efforts to effect such a reduction. Landlord shall have sole control and discretion in its efforts to obtain such reduction in assessments. Landlord shall credit against Taxes any tax refund payable as a result of any proceeding instituted pursuant to this Section 6.3.4. In the event Landlord is successful in obtaining such reduction in the assessed valuation of the Building, all reasonable costs and expenses incurred by Landlord in such endeavor shall be included in Taxes up to the amount of any tax refund payable. To the extent the costs of such proceedings exceed any tax refund or in the event such proceedings are unsuccessful, all such reasonable costs and expenses incurred by Landlord shall be Tenant’s sole responsibility and shall be charged to Tenant as additional rent. Tenant shall be entitled to the refund of any excess Taxes attributable to Taxes, penalties, fines and interest thereon received by Landlord which has been paid by Tenant or which has been paid by Landlord but for which Landlord has been previously reimbursed in full by Tenant, such amount to be paid within thirty (30) days after receipt by Landlord.

6.4 Rent Adjustments for Building Expenses.

6.4.1 On or before March 31 of each Lease Year, Landlord shall compute the Building Expenses for such year and shall allocate such costs to the Rentable Area of the Building in the following manner: Building Expenses shall be totaled and such total shall be divided by the total Rentable Area of the Building thereby deriving the “Cost of Building Expenses Per Square Foot” of rentable area.

6.4.2 In the event that the cost of Building Expenses Per Square Foot of rentable area for any year after calendar year 2005 which is wholly or partly within the Term are greater than the Base Year Building Expenses, Tenant shall pay to Landlord, as additional rent, the amount of such excess times the number of square feet of Rentable Area of the Premises, as set forth in Section 1 above. If, during any year that Tenant is not leasing 100% of the Building, occupancy of the Building during any calendar year is less than one hundred percent (100%), then Building Expenses for that calendar year shall be "grossed up" to that amount of Building Expenses that, using reasonable projections, would normally be expected to be incurred during the calendar year in question if the Building was one hundred percent (100%) occupied during the applicable calendar year period, as determined under generally accepted accounting principles; it being understood that the written statement submitted to Tenant shall provide a reasonably detailed description of how the Building Expenses were grossed up and that only those component expenses that are affected by variations in occupancy levels shall be grossed up. Notwithstanding the provisions of Section 1.1.11, in the event Tenant does not fully occupy the Building during the entire Base Year for Building Expenses, then the Base year for Building Expenses shall be the first twelve (12) calendar months that Tenant fully occupies the Building, provided that if Tenant does not fully occupy the Building within eighteen (18) months after the Commencement Date, the Base Year Building Expenses shall be grossed up using the last twelve (12) months of the eighteen (18) month period. Such additional rent shall be computed on a year-to-year basis. No later than fifteen (15) days prior to the start of each calendar year, Landlord will deliver to Tenant its reasonable estimate of such additional rent with respect to Building Expenses, and require Tenant to pay each month, in advance, during such year 1/12 of such amount, at the time of payment of monthly installments of Base Rent. Tenant shall have the right to examine, at Tenant's sole expense, Landlord's records with respect to any such increases in Building Expenses; provided, however, that unless Tenant shall have given Landlord written notice of exception to any such statement within thirty (30) days after delivery thereof, Tenant shall pay the same for the balance of the year, subject to Tenant’s audit rights. If Landlord has not delivered the estimate of Building Expenses to Tenant by the first day of January of the applicable calendar year, Tenant will continue paying Tenant’s Share of Building Expenses based on the Building Expense estimate for the previous calendar year until the new estimate of Building Expenses is delivered. Tenant shall pay any additional rent owed as a result of increased Building Expenses within thirty (30) days after delivery thereof, the same shall be conclusive and binding on Tenant for the applicable year, subject to Tenant’s audit rights. Any such additional rent shall be due within thirty (30) days after Landlord has submitted a written statement to Tenant showing the amount due. No credit shall be given to Tenant if the cost of Building Expenses Per Square Foot are less than the Base Year Building Expenses. Notwithstanding anything to the contrary contained herein, Landlord shall use diligent efforts to keep Building Expenses at reasonable amounts, while maintaining the Building as a first class office building.

6.4.3 Tenant shall have the right to (i) provide its own janitorial services to all or any portion of the Premises, and/or (ii) require modifications to the standard office janitorial service as described in Exhibit “J” hereto. If Tenant chooses to provide and/or modify such services, Landlord and Tenant shall enter into an amendment to this Lease which reduces or increases, as the case may be, the Annual Base Rent due hereunder from the date Tenant provides such services or requires such modifications, as the case may be by the amount of any savings or increased cost and adjusts the Base Year Building Expenses proportionately. Landlord and Tenant acknowledge and agree that the cost included in the stated Annual Base Rent for standard unescorted, after-hours janitorial services is Eighty Cents ($0.80) per rentable square foot.

6.5 Additional Rent Payments. Tenant’s obligation to pay any additional rent accruing during the Term pursuant to Sections 6.3 and 6.4 hereof shall apply pro rata to the proportionate part of a calendar year as to Taxes and Building Expenses, in which this Lease ends, for the portion of such year during which this Lease is in effect. Such obligation to make payments of such additional rent shall survive the expiration or sooner termination of the Term for one (1) year.

6.6 Payments. All payments or installments of any rent hereunder and all sums whatsoever due under this Lease (including but not limited to court costs and attorneys fees) shall be deemed rent, shall be paid to Landlord at the address designated by Landlord. If any amount of Annual Base Rent or additional rent shall remain unpaid for ten (10) calendar days after written notice that such payment is past due (provided, that in no event shall Landlord be required to give more than two (2) written notices in any twelve (12) month period) , Tenant shall pay Landlord, without notice or demand, a late charge equal to the greater of (i) $35.00 and (ii) five percent (5%) of such overdue amount to partially compensate Landlord for its administrative costs in connection with such overdue payment; which administrative costs Tenant expressly acknowledges are reasonable and do not constitute a penalty. In addition, such overdue amounts shall bear interest at the rate of 15% per annum, but not more than the maximum allowable legal rate applicable to Tenant (the “Default Rate”) until paid. Additionally, if any of Tenant’s checks for payment of rent or additional rent are returned to Landlord for insufficient funds, Tenant shall pay to Landlord as additional rent $50.00 for each such check returned for insufficient funds. Time is of the essence in this Lease. No invoice, nor any request for unscheduled additional rent, shall be sufficient unless accompanied by receipts or other reasonably adequate documentation sufficient to support the amount requested to be paid pursuant to the invoice.

6.7 Annual Taxes and Building Expense Statement. From and after the Rent Commencement Date, after the end of each calendar year, Landlord shall submit to Tenant a statement prepared by Landlord’s property management company (the “Taxes and Building Expense Statement”) setting forth in reasonable detail the Taxes and Building Expenses for such calendar year and the amount (if any) of Tenant’s Share of Building Expenses and Taxes for such calendar year. If Tenant’s Share of the Building Expenses and Taxes so stated is more than the amount (if any) theretofore paid by Tenant for Building Expenses and Taxes for the period covered by the Taxes and Building Expense Statement, Tenant shall pay to Landlord the deficiency within thirty (30) days after the submission of the Taxes and Building Expense Statement. If Tenant’s Share of the Building Expenses or Tenant’s Share of Taxes so stated is less than the amount (if any) theretofore paid by Tenant for Building Expenses or Taxes for the period covered by the Taxes and Building Expense Statement, Landlord shall credit the excess against the next monthly installment of Annual Base Rent thereafter payable by Tenant under this Lease, except that Landlord shall refund the excess (if any) for the calendar year ending with or within the last Lease Year to Tenant within forty-five (45) days after submission of the Taxes and Building Expense Statement for such calendar year. Tenant’s obligation under this subsection to pay Tenant’s Share of Building Expenses and Taxes and Landlord’s obligation to reimburse Tenant for any overpayment shall survive the expiration of the Term or the earlier termination of this Lease for one (1) year.

6.8 Disputes. Each statement of Taxes and Building Expenses shall be in a form sufficiently detailed and complete for Tenant’s adequate review, sent to Tenant shall be conclusively binding upon Tenant unless Tenant shall (i) within thirty (30) days after such statement is sent, pay to Landlord the amount set forth in such statement, without prejudice to Tenant’s right to dispute such statement, and (ii) within one hundred eighty (180) days after such statement is received, give notice to Landlord objecting to such statement and specifying the reasons that such statement is claimed to be incorrect. No such objection shall prejudice Tenant’s right to make further objections with respect to the same statement within the permitted time periods. Tenant shall have the right at its sole cost and expense to review or audit Landlord’s books and records relating to Landlord’s calculation of Building Expenses and Taxes at any time within two years from Tenant’s receipt of the statement, and may use the auditor or reviewer of its choice provided such auditor’s area of expertise includes lease expense analysis. If the parties are unable to resolve a dispute as to the correctness of a statement within thirty (30) days following Tenant’s notice of objection, either party may refer the issues raised to an accountant reasonably acceptable to the other party and that has not and does not provide accounting and consulting services to Landlord or Tenant and does not otherwise have any affiliation or business relationship with Landlord or Tenant, and the decision of such accountants shall be conclusively binding upon Landlord and Tenant. The fees and expenses relating to the accountant hired to conclusively resolve the dispute as to the correctness of the statement shall be borne by the unsuccessful party (and if both parties are partially unsuccessful, the accountants shall apportion the fees and expenses between the parties based on the degree of success of each party). In the event there is an adjustment of the statement, the amount owed by either party shall be increased by interest on the sum owed calculated at the Default Rate from the date of the original payment until the date the adjustment is paid

7. Requirements of Applicable Law. Landlord warrants that on the Commencement Date, the Premises shall comply with the Association Declaration and all applicable Federal, State and local laws, codes, ordinances, rules and regulations of governmental authorities having jurisdiction over the Property, including, but not limited to, zoning rules and regulations and the Americans with Disabilities Act (“Applicable Laws”). Tenant, at its sole cost and expense, shall comply promptly with all Applicable Laws first enacted after the Rent Commencement Date, which impose any duty upon Landlord or Tenant with respect to the use, occupancy or alteration of the Premises or any part thereof and for the prevention of fires; provided, however, that Landlord and not Tenant shall correct all structural defects in the Building necessary to comply with Applicable Laws, and make all repairs, changes or alterations necessary because the Building was not constructed in compliance with any of the Applicable Laws.

8. Certificate of Occupancy. Tenant shall not use or occupy the Premises in violation of any certificate of occupancy, permit, or other governmental consent issued for the Building. If any governmental authority, after the commencement of the Term, shall contend or declare that the Premises are being used for a purpose which is in violation of such certificate of occupancy, permit, or consent, then Tenant shall, upon five (5) days’ notice from Landlord, immediately discontinue such use of the Premises. If thereafter the governmental authority asserting such violation commences or continues criminal or civil proceedings against Landlord for Tenant’s failure to discontinue such use, in addition to any and all rights, privileges and remedies given to Landlord under this Lease for default therein, Landlord shall have the right to terminate this Lease forthwith.

9. Contest-Statute, Ordinance, Etc. Tenant may, after notice to Landlord, by appropriate proceedings conducted promptly at Tenant’s own expense in Tenant’s name and whenever necessary in Landlord’s name, contest in good faith the validity or enforcement of any Applicable Laws and may similarly contest any assertion of violation of any certificate of occupancy, permit, or any consent issued for the Building. Tenant may, pending such contest, defer compliance therewith if, such deferral shall not subject either Landlord or the Premises or the Property (or any part thereof) to any penalty, fine or forfeiture, and if Tenant shall post a bond with corporate surety approved by Landlord sufficient, in Landlord’s opinion, fully to indemnify Landlord from loss.

10. Tenant’s Improvements.

10.1 Except to the extent that Landlord is responsible for making improvements to the Premises pursuant to Section 35 of this Lease and subsequent to the installation of Tenant’s Work pursuant to Section 35, Tenant shall make such improvements to the Premises as it may deem necessary at its sole cost and expense. Notwithstanding anything herein to the contrary, Tenant shall have the right to make non-structural alterations which do not affect the mechanical, electrical or plumbing systems of the Building without obtaining Landlord’s prior consent, provided that either (i) such alterations cost less than Fifty Thousand Dollars ($50,000.00) per occurrence during the Initial Term and One Hundred Thousand Dollars ($100,000,00) during any of the Renewal Term(s), or (ii) are items of decoration, painting or carpeting. Landlord will notify Tenant of Landlord’s election to consent or withhold its consent within ten (10) days after receiving Tenant’s written request for consent to an alteration. If Landlord does not respond within such ten (10) day period, Landlord shall be deemed to have given consent to the proposed alteration. Landlord’s consent to and/or approval of Tenant’s plans and specifications for the aforesaid improvements shall create no responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with all laws, rules and regulations of governmental agencies or authorities. All alterations, installations, additions or improvements made by either of the parties hereto upon the Premises, (except for Tenant’s movable office fixtures, furniture and equipment, trade fixtures, generators, uninterruptible power sources, supplemental HVAC equipment in addition to the base building systems, and other items identified by Tenant prior to the Rent Commencement Date or, after the Rent Commencement Date, as mutually agreed upon in writing, collectively, “Tenant’s Personal Property”), shall be the property of Landlord and shall remain upon and be surrendered with the Premises at the termination of this Lease without molestation or injury. Except for Tenant’s Personal Property, Tenant shall have no obligation to remove any improvements to the Premises, made by or on behalf of Tenant, including, without limitation, the Tenant’s Work. If Tenant fails to remove any of Tenant’s Personal Property items, Landlord shall have the right, but not the obligation, to remove and dispose of such items, and restore the Premises accordingly and Tenant shall reimburse Landlord for the costs of such removal, disposal and restoration within thirty (30) days after receipt of an invoice therefore, together with interest at the Default Rate, which shall accrue form the date the costs were incurred by Landlord.

10.2 Notwithstanding anything herein to the contrary, within six (6) months after the expiration or sooner termination of the Term, Landlord, at Tenant’s expense, shall have the right to remove all of the improvements comprising the auditorium in the Building and restore the level of the floor of such area to match the grade of the balance of the first floor area (the “Restoration Costs”). In no event shall the Restoration Costs exceed the lesser of (i) $67,000.00, or (ii) the amount of costs actually incurred by Landlord. Tenant shall reimburse Landlord for such costs within thirty (30) days after receipt of a written invoice for such Restoration Costs, together with reasonable supporting documentation. Tenant’s obligations under this Section 10.2 shall survive the expiration or sooner termination of this Lease, unless the parties have agreed specifically in writing that the provisions of this Section 10.2 shall be of no further force and effect. If Landlord fails to remove such improvements and restore the level of the floor of such area within the six (6) month period, Tenant shall have no obligation to reimburse Landlord for the Restoration Costs and the provisions of this Section 10.2 shall be of no further force or effect.

11. Repairs and Maintenance.

11.1 Tenant’s Care of the Premises and Building. During the Term Tenant shall:

(i) keep the Tenant’s Personal Property and the fixtures, appurtenances and equipment installed on the Premises in good order and condition, except to the extent such maintenance is the obligation of Landlord pursuant to Section 11.2;

(ii) make repairs and replacements to the Premises required because of Tenant’s misuse or primary negligence, except to the extent that the repairs or replacements are covered by Landlord’s insurance as required hereunder;

(iii) not commit waste.

In addition, Tenant shall not place a load upon any floor of the Premises exceeding the floor load per square foot area which such floor was designed to carry and which may be allowed under Applicable Laws. Landlord reserves the right to prescribe the weight and position of all heavy equipment brought onto the Premises and prescribe any reinforcing required under the circumstances, all such reinforcing to be at Tenant’s expense.

11.2 Landlord’s Repairs. Except for the repairs and replacements that Tenant is required to make pursuant to Section 11.1 above, Landlord shall make all repairs and replacements to the Premises (excluding items of the Tenant’s Work such as wall coverings, carpeting and the like, but including extensions of the Base Building Systems, such as additional sprinkler heads, VAV boxes, supplemental HVAC units, plumbing systems and the like), Common Areas and the Building (including Building fixtures and equipment) as shall be reasonably deemed necessary to maintain the Building in a condition comparable to other newly constructed first class suburban office buildings of comparable quality in the Baltimore‑Washington corridor area (“Comparable Buildings”). If Tenant constructs Tenant’s Work pursuant to the terms of Section 35, to the extent that Tenant installs items as part of its improvements that Landlord is responsible to maintain during the Term, Tenant shall transfer any warranties to Landlord. Without limiting the foregoing, this maintenance shall include (a) the roof, foundation, exterior walls and windows (including interior sprandrel systems and gaskets), interior structural walls, all structural components (including the foundation), and all systems such as mechanical, electrical, HVAC and plumbing, (b) all landscaping and parking areas at the Property (including snow removal and repair); (c) all other repairs deemed reasonably necessary for the prudent management of the Premises or as requested by Tenant. The costs associated with such repairs shall be deemed a part of Building Expenses; provided, however, that (i) costs of all of such repairs which would be considered capital in nature under generally accepted accounting principles shall be paid by Landlord, (ii) the portion of the costs which are covered by warranties shall not be included in the Building Expenses. There shall be no allowance to Tenant for a diminution of rental value, no abatement of rent, and no liability on the part of Landlord by reason of inconvenience, annoyance or injury to business arising from Landlord, Tenant or others making any repairs or performing maintenance as provided for herein. Landlord agrees to diligently attend to any repairs or maintenance needs brought to its attention by written notice from Tenant as soon as reasonably practicable (but in no event shall Landlord commence such repairs or maintenance later than five (5) days (or shorter period as may be reasonably required in an emergency) thereafter or cease to pursue the completion of such repair with diligence) and in a commercially reasonable manner calculated to minimize to the extent possible disruption of Tenant’s business activities.

11.2.1 Failure to Repair or Maintain. If either party fails within the time periods required by this Lease (or such shorter period as may be required in an emergency) to proceed with diligence to make any required repairs or perform any maintenance, the other party may do so and the non-performing party shall reimburse the performing party for within thirty (30) days after receipt of a written invoice for all reasonable, out-of-pocket costs and expenses incurred on account thereof, together with interest at the Default Rate from the date that such costs and expenses were incurred. If Landlord fails to pay the amounts due in connection with this Section, Tenant shall have no rights to offset such amounts against future obligations to pay Annual Base Rent or additional rent until Tenant has received a final, unappealable, adjudicatory decision.

11.2.2 Interruptions Due to Repairs.

(a) Landlord shall minimize interference with Tenant’s use and occupancy of the Premises during the making of any repairs, alterations, additions, improvements, repairs or replacements, Landlord shall provide Tenant with reasonable notice of the scope and schedule of any such work and, in the event that the completion thereof is reasonably likely to disrupt (other than in a de minimis manner) the operation of Tenant’s business at the Premises, Landlord shall perform such work during non-business hours. Except as expressly provided in this Lease to the contrary, there shall be no allowance to Tenant for a diminution of rental value, no abatement of rent, and no liability on the part of Landlord by reason of inconvenience, annoyance or injury to business arising from Landlord, Tenant or others making any repairs or performing maintenance as provided for herein.

(b) Notwithstanding anything to the contrary contained in this Lease, if Tenant is unable to use the Building (or any portion thereof) for the ordinary conduct of Tenant’s business due to an interruption of an Essential Service (as hereinafter defined) resulting from (a) Landlord’s performance of an alteration, addition, impairment, repair or replacement to the Premises, or due to Landlord’s entry into the Premises, or for any other reason within Landlord’s or its agent’s reasonable control, or (b) any of the causes described in Section 27 hereof, and such condition continues for a period in excess of six (6) consecutive days after (i) Tenant furnishes a notice to Landlord (the “Abatement Notice”) stating that Tenant’s inability to so use the Premises (or portion thereof) is due to such condition, and (ii) Tenant does not actually use or occupy the Premises (or portion thereof) during such period for the ordinary conduct of its business, then Annual Base Rent, Taxes and Building Expenses for such portion of the Building that is both untenantable and unoccupied (determined based upon the ratio which the square footage of such portion of the Building, determined using the BOMA Standard bears to the Rentable Area of the Building) shall be abated on a per diem basis for the period commencing on the seventh (7^th) date after the Essential Service is interrupted and ending on the earlier of (x) the date Tenant reoccupies such portion of the Premises for the ordinary conduct of its business, and (y) the date on which such condition is remedied in all material respects. “Essential Service” shall mean any of the service and utilities described in Section 23 hereof.

11.3 Time for Repairs. Repairs or replacements required pursuant to Section 11.1 and 11.2 above shall be made within a reasonable time except in matters of security and safety in which case the repairs shall be made as expeditiously as possible (depending on the nature of the repair or replacement needed - generally no more than fifteen (15) days) after receiving notice or having actual knowledge of the need for a repair or replacement.

11.4 Surrender of the Premises. Upon the termination of this Lease, Tenant shall surrender the Premises to Landlord in the same broom clean condition that the Premises were in on the date the Tenant’s Work is substantially completed except for:

(i) ordinary wear and tear;

(ii) damage by the elements, fire, and other casualty unless Tenant would be required to repair under the provisions of this Lease;

(iii) damage arising from any cause not required to be repaired or replaced by Tenant; and

(iv) alterations as permitted by this Lease unless consent was conditioned on their removal.

On surrender, Tenant shall remove from the Premises its Tenant’s Personal Property and repair any damage to the Premises caused by its removal. Any items not removed by Tenant as required above shall be considered abandoned. Landlord may dispose of abandoned items as Landlord chooses and ▇▇▇▇ Tenant for the cost of their disposal.

12. Conduct on Premises. Tenant shall not do, or permit anything to be done in the Premises, or bring or keep anything therein which shall, in any way, increase the rate of fire insurance on the Building, or invalidate or conflict with the fire insurance policies on the Building, fixtures or on property kept therein, or obstruct or interfere with the rights of Landlord or of other tenants, or in any other way injure or annoy Landlord or the other tenants, or subject Landlord to any liability for injury to persons or damage to property, or interfere with the good order of the Building, or conflict with Applicable Laws, or the Maryland Fire Underwriters Rating Bureau. Tenant agrees that any increase of fire insurance premiums on the Building or contents caused by the occupancy of Tenant, Tenant's employees, agents, servants, or invitees shall, as they accrue be added to the rent heretofore reserved and be paid as a part thereof; and Landlord shall have all the rights and remedies for the collection of same as are conferred upon Landlord for the collection of rent provided to be paid pursuant to the terms of this Lease.

13. Insurance.

13.1 Tenant’s Insurance. Tenant shall keep in force at its own expense, so long as this Lease remains in effect, (a) public liability insurance, including insurance against assumed or contractual liability under this Lease, with respect to the Premises, to afford protection with limits, per person and for each occurrence, of not less than Two Million Dollars ($2,000,000), combined single limit, with respect to personal injury and death and property damage, such insurance to provide for only a reasonable deductible, (b) all-risk property and casualty insurance, including theft, written at replacement cost value and with replacement cost endorsement, covering all of Tenant’s personal property in the Premises and all improvements and installed in the Premises by or on behalf of Tenant whether pursuant to the terms of Section 35, Section 10, or otherwise, such insurance to provide for only a reasonable deductible, (c) if, and to the extent, required by law, workmen’s compensation or similar insurance offering statutory coverage and containing statutory limits, (d) insurance of all plate and other interior glass in the Premises for and in the name of Landlord, and (e) business interruption insurance in an amount sufficient to reimburse Tenant for loss of earnings attributable to prevention of access to the Building or the Premises for a period of at least twelve (12) months. Such policies shall be maintained in companies and in form reasonably acceptable to Landlord and shall be written as primary policy coverage and not contributing with, or in excess of, any coverage which Landlord shall carry. Tenant shall deposit the policy or policies of such required insurance or certificates thereof with Landlord prior to the Commencement Date, which policies shall name Landlord or its designee and, at the request of Landlord, its mortgagees, as additional insured and shall also contain a provision stating that such policy or policies shall not be canceled except after thirty (30) day’s written notice to Landlord or its designees. All such policies of insurance shall be effective as of the date Tenant occupies the Premises and shall be maintained in force at all times during the Term of this Lease and all other times during which Tenant shall occupy the Premises. Any insurance required of Tenant hereunder may be furnished by Tenant under a blanket policy carried by it, provided that such blanket policy shall contain an endorsement that names Landlord as an additional insured, specifically references the Premises, and guarantees a minimum limit available for the Premises equal to or greater than the insurance amounts required under this Article.

In addition to the foregoing insurance coverage, Tenant shall require any contractor retained by it to perform work on the Premises to carry and maintain, at no expense to Landlord, during such times as contractor is working in the Premises, a non-deductible (i) comprehensive general liability insurance policy, including, but not limited to, contractor’s liability coverage, contractual liability coverage, completed operations coverage, broad form property damage endorsement and contractor’s protective liability coverage, to afford protection with limits per person and for each occurrence, of not less than Two Hundred Thousand Dollars ($200,000.00), combined single limit, with respect to personal injury and death and property damage, such insurance to provide for no deductible, and (ii) workmen’s compensation insurance or similar insurance in form and amounts as required by law.

In the event of damage to or destruction of the Premises and the termination of this Lease by Landlord pursuant to Section 18 herein, Tenant agrees that it shall pay Landlord all of its insurance proceeds relating to improvements made in the Premises by or on behalf of Tenant whether pursuant to the terms of Section 35, Section 10, or otherwise. If Tenant fails to comply with its covenants made in this Section, if such insurance would terminate or if Landlord has reason to believe such insurance is about to be terminated, Landlord may at its option cause such insurance as it in its sole judgment deems necessary to be issued, and in such event Tenant agrees to pay promptly upon Landlord’s demand, as additional rent the premiums for such insurance.

13.2 Landlord’s Insurance. Throughout the Term, Landlord shall maintain standard All Risk Coverage insurance on the Premises, including the Base Building Shell, Tenant’s Work and subsequent alterations (but excluding Tenant Personal Property) insuring against such perils as are normally insured against by prudent owners of Comparable Buildings for the full replacement value thereof; provided, however, Landlord shall only be required to maintain insurance for Tenant’s Work and subsequent alterations to the extent Tenant has provided Landlord the Construction Documents (as defined in Section 35), the construction documents for any alteration, and reasonably detailed schedules satisfactory to Landlord’s insurer, describing the property to be insured. Without limitation, such insurance shall include: (i) insurance on the Building and other improvements and its property therein against fire and casualty and other risks as may be included in extended coverage casualty insurance in an amount equal to full replacement value of the Building, and rent loss insurance protecting Landlord against abatement or loss of rent in an amount equal to the rent and additional rent paid by Tenant under this Lease. Landlord shall include within the coverage of its fire and extended coverage insurance any improvements and betterments which may be made on behalf of or paid by the Tenant to the extent that same are customarily insurable as part of the realty; (ii) comprehensive general liability insurance with a minimum combined single limit of liability of $2,000,000 for the protection of the Landlord against all claims for bodily injury (including death) and for the property damage incurred in, or about the Premises for which the Landlord is legally liable, in respect of injury in or about the Premises or death of one or more persons, in respect of one or more occurrences, and in respect of damage to property and including all contractual obligations coverage and including actions of the employees, contractors, subcontractors, invitees, agents and others working on behalf of the Landlord; (iii) broad boiler and machinery insurance covering property damage; and (iv) such other insurance as it is or may become customary for owners of Comparable Buildings to carry for loss of or damage to the property, or liability arising therefrom. Such insurance shall be maintained with an insurance company authorized to do business in the State of Maryland, with a then current ▇▇▇▇▇▇ ▇. Best Company, Inc. (or if it no longer exists, a comparable rating service) general policy maker’s rating of A- or better and financial size category of Class X or higher. Landlord shall promptly deliver to Tenant notice of (i) any substitution of such company or companies, and (ii) any change in their ▇▇▇▇▇▇ ▇. Best Company, Inc. general policy maker’s rating of any such company or substituted company. The deductible on Landlord’s All Risk Coverage Insurance shall not exceed One Hundred Thousand Dollars ($100,000.00) or such greater amount as may customarily be accepted from time to time by prudent owners of Comparable Buildings. Landlord shall name Tenant as an additional insured on Landlord’s public liability insurance policy.

13.3 Waiver of Subrogation. Each party hereto waives claims arising in any manner in its favor and against the other party and agrees that neither party hereto shall be liable to the other party or to any insurance company (by way of subrogation or otherwise) insuring the other party for any loss or damage to the Building, the Premises or other tangible property, or any resulting loss of income, or losses under worker’s compensation laws and benefits, or against liability on or about the Building, even though such loss or damage might have been occasioned by the negligence of such party, its agents or employees if any such loss or damage is covered by insurance benefiting the party suffering such loss or damage as was required to be covered by insurance carried pursuant to this Lease. Landlord shall cause each insurance policy carried by it insuring against liability on or about the Building or insuring the Premises and the Building or income resulting therefrom against loss by fire or any of the casualties covered by the all-risk insurance carried by it hereunder to be written in such a manner as to provide that the insurer waives all right of recovery by way of subrogation against Tenant in connection with any loss or damage covered by such policies. Tenant shall cause each insurance policy carried by it insuring against liability or insuring the Tenant’s Personal Property against loss by fire or any of the casualties covered by the all-risk insurance required hereunder to be written in such a manner as to provide that the insurer waives all right of recovery by way of subrogation against Landlord in connection with any loss or damage covered by such policies.

14. Rules and Regulations. Tenant shall be bound by the rules and regulations set forth on the schedule attached hereto as Exhibit “B” and made a part hereof, provided, that in case of any conflict or inconsistency between the provisions of this Lease and any of the rules and regulations as originally promulgated or as supplemented or amended from time to time, the provisions of this Lease shall control. Landlord shall have the right, from time to time, subject to Tenant’s prior consent as long as Tenant leases at least seventy-five percent (75%) of the Building, to issue additional or amended rules and regulations regarding the use of the Building, so long as the rules shall be reasonable, non-discriminatory between tenants, impose no cost on Tenant, do not reduce any rights of Tenant under this Lease. When so issued the same shall be considered a part of this Lease and Tenant covenants that the additional or amended rules and regulations shall likewise be faithfully observed by Tenant, the employees of Tenant and all persons invited by Tenant into the Building.

15. Mechanics’ Liens. Tenant shall not do or suffer to be done any act, matter or thing whereby Tenant’s interest in the Premises, or any part thereof, may be encumbered by any mechanics’ lien. Tenant shall discharge by payment, filing of a bond, or otherwise, within thirty (30) days after the date of filing, any mechanics’ liens filed against Tenant’s interest in the Premises, or any part thereof, purporting to be for labor or material furnished or to be furnished to Tenant. Landlord shall not be liable for any labor or materials furnished or to be furnished to Tenant upon credit, and no mechanics’ or other lien for labor or materials shall attach to or affect the reversionary or other estate or interest of Landlord in and to the Premises, or the Property.

16. Tenant’s Failure to Repair. In the event that Tenant fails after thirty (30) days prior written notice from Landlord, to keep the Premises in a good state of condition and repair pursuant to Section 11 above, or to do any act or make any payment required under this Lease or otherwise fails to comply herewith, Landlord may, at its option (but without being obliged to do so) immediately, or at any time thereafter and without notice, perform the same for the account of Tenant, including the right to enter upon the Premises at all reasonable hours to make such repairs, or do any act or make any payment or compliance which Tenant has failed to do, and upon demand, Tenant shall reimburse Landlord for any reasonable out of pocket expense incurred by Landlord including but not limited to any costs, damages and reasonable counsel fees. Any moneys expended by Landlord, as aforesaid, shall be deemed additional rent, collectible as such by Landlord. All rights given to Landlord in this Section shall be in addition to any other right or remedy of Landlord herein contained.

17. Property -- Loss, Damage. Landlord, its agents and employees shall not be liable to Tenant for (i) any damage or loss of property of Tenant placed in the custody of persons employed to provide services for or stored in or about the Premises and/or the Building, unless such damage or loss is the result of the negligence of Landlord, and (ii) interference with the light, air, or other incorporeal hereditaments of the Premises.

18. Destruction -- Fire or Other Casualty. In case of damage to the Premises by fire or other casualty insured against by Landlord, Tenant shall give immediate notice thereof to Landlord, who shall thereupon cause damage to all property owned by it to be repaired with reasonable speed at expense of Landlord to substantially the condition of the Premises prior to the damage, subject to customary requirements of any mortgage regarding placement of proceeds into trust, submitting requisitions, etc., due allowance being made for reasonable delay which may arise by reason of adjustment of loss under insurance policies on the part of Landlord and/or Tenant, and for reasonable delay on account of “labor troubles” or any other cause beyond Landlord’s control. To the extent that the Premises are rendered untenantable in whole or in part the rent shall proportionately ▇▇▇▇▇ from the date of such casualty. In the event the damage shall be so extensive as to render the whole Building untenantable or not reasonably usable by Tenant for its business purposes, then this Lease, at the option of Tenant or Landlord, shall be terminated upon written notice and the rent shall, in such event, be paid to or adjusted as of the date of such damage, and the terms of this Lease shall expire by lapse of time and conditional limitation upon the third day after such notice is mailed, and Tenant shall thereupon vacate the Premises and surrender the same to Landlord, but no such termination shall release either party from any liability such party to the other arising from such damage or from any breach of the obligations imposed on such party hereunder, or from any obligations accrued hereunder prior to such termination.

In addition, in the event that (a) Landlord fails to notify Tenant of the estimated time to complete the restoration within thirty (30) days after the casualty, (b) Landlord estimates that its repairs will take more than two hundred seventy (270) days for any areas of the Premises, or (c) Tenant is actually deprived of the use of all or any substantial portion of the Premises for a period in excess of two hundred seventy (270) days for any areas of the Premises, Tenant shall have the right, by written notice to Landlord to terminate the Lease as of the date of the casualty, provided that Tenant gives its notice within (45) days after the date of the casualty in the case of subparagraph (a) above, within thirty (30) days after receipt of Landlord’s notice of the estimated time to complete the restoration or repair in the case of subparagraph (b) above, or within thirty (30) days after failing to meet the deadline set forth in subparagraph (c) above. .

19. Eminent Domain.

(a) If all or substantially all of the Building shall be acquired or condemned for any public or quasi-public purpose, other than on a temporary basis, this Lease shall terminate and the Term shall end as of the date of the vesting of title and rent shall be prorated and adjusted as of such date.

(b) If only a part of the Building shall be acquired or condemned then, except as hereinafter provided in this Section 19, this Lease and the Term shall continue in full force and effect, provided that from and after the date of the vesting of title, the rent shall be equitably reduced to reflect the reduction of the Premises as a result of such acquisition or condemnation.

(c) If (i) the part of the Premises so acquired or condemned contains more than thirty-three percent (33%) of the total area of the Building and such condemnation lasts for a period of 120 days, or (ii) if, by reason of such acquisition or condemnation, Tenant no longer has reasonable means of access to the Premises (including the Building and the parking lot) for more than 120 consecutive days, then Tenant may terminate this Lease by notice to Landlord given within thirty (30) days following the date upon which Tenant received notice of such acquisition or condemnation. If Tenant so notifies Landlord, this Lease shall end and expire upon the thirtieth (30^th) day following the giving of such notice. If a part of the Premises shall be so acquired or condemned and this Lease and the Term shall not be terminated in accordance with this Section 19 Landlord, at Landlord’s expense, but without requiring Landlord to spend more than it collects as an award, shall, subject to the provisions of any mortgage, restore that part of the Premises not so acquired or condemned to a self-contained rental unit as substantially equivalent as reasonably possible (with respect to character, quality, appearance and services) to that which existed immediately prior to such acquisition or condemnation, excluding Tenant’s Personal Property and Annual Base Rent shall be equitably reduced for the balance of the Term.

(d) Upon any termination of this Lease pursuant to the provisions of this Section 19, rent shall be apportioned as of, and shall be paid or refunded up to and including, the date of such termination. This provision shall survive expiration or earlier termination of the Lease.

(e) If all or any part of the Premises is acquired or condemned for less than 120 days during the Term for any public or quasi-public use or purpose, Tenant shall give prompt notice to Landlord and the Term shall not be reduced or affected in any way and Tenant shall perform all of its other obligations under this Lease, except to the extent prevented from doing so by the condemning authority, provided that rent shall be proportionally abated for the amount of time any such part of the Premises is unusable by Tenant and Tenant shall be entitled to receive any award or payment from the condemning authority for such use.

In case of any taking or condemnation, whether or not the Term of this Lease shall cease and terminate, the entire award shall be the property of Landlord, and Tenant hereby assigns to Landlord all its right, title and interest in and to any such award, except that Tenant shall be entitled to claim, prove and receive in the proceedings such awards as may be allowed for moving expenses, loss of profit and fixtures and other equipment installed by it, any improvements which it may or is required to remove at the end of the Term of this Lease, and an amount with respect to Tenant’s improvements and alterations (including those described in Article 35) in excess of the then unamortized amount (amortized over ten (10) years) of the Allowance and the Amortized Allowance, and also for any item which shall not, under the terms of this Lease, be or become the property of Landlord at the termination hereof and any other amount allowed by law.

20. Assignment. So long as Tenant is not in default of any of the terms and conditions hereof, after the giving of all required notices and the expiration of all cure periods, Landlord shall not unreasonably withhold its consent to an assignment of this Lease or sublease of the Premises (a “Transfer”) for any of the then remaining portion of the unexpired Term or any portion of the Premises provided: (i) the net assets of the assignee or sublessee (a “Transferee”) shall be sufficient in Landlord’s reasonable determination to perform its obligations under the proposed assignment or sublease; (ii) in the event of an assignment, such Transferee shall assume in writing all of Tenant’s obligations under this Lease; (iii) in the event of a sublease, such sublease shall in all respects be subject to and in conformance with the terms of this Lease; and (iv) in all events Tenant continues to remain liable on this Lease for the performance of all terms, including but not limited to, payment of all rent due hereunder. Landlord will notify Tenant of Landlord’s election to consent or withhold its consent within ten (10) days after receiving Tenant’s written request for consent to a Transfer. If Landlord does not respond within such ten (10) day period, Landlord shall be deemed to have given consent to the proposed Transfer. If this Lease is assigned, or if the Premises or any part thereof is underlet or occupied by anybody other than Tenant, Landlord may, after default by Tenant, collect rent from the assignee, undertenant or occupant and apply the net amount collected to the rent herein reserved, but no such collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, undertenant or occupant as tenant, or a release of Tenant from the further observance and performance by Tenant of the covenants herein contained. For purposes of the foregoing, a transfer by operation of law or transfer of a controlling interest in Tenant as same exists as of the date hereof, shall be deemed to be an assignment of this Lease. No Transfer, regardless of whether Landlord’s consent has been granted or withheld, shall be deemed to release Tenant from any of its obligations nor shall the same be deemed to release any person guaranteeing the obligations of Tenant hereunder from their obligations as guarantor. Landlord’s acceptance of any name submitted by Tenant, an agent of Tenant, or anyone acting by, through or under Tenant for the purpose of being listed on the Building directory will not be deemed, nor will it substitute for, Landlord’s consent, as required by this Lease, to any Transfer or other occupancy of the Premises by anyone other than Tenant or Tenant’s employees. Fifty percent (50%) of any profit or additional consideration or rent in excess of the Annual Base Rent or additional rent payable by Tenant hereunder (after taking into account tenant improvements for the proposed assignee or sublessee, legal fees and leasing commissions, undepreciated costs of tenant improvements made to the Premises by Tenant (or by Landlord at Tenant’s request and at Tenants’ expense) in excess of the Allowance and other costs and expenses Tenant incurs in connection with the Transfer) which is payable to Tenant as a result of any assignment or subletting shall be paid to Landlord as additional rent when received by Tenant. All the foregoing notwithstanding, Tenant shall not enter into any lease, sublease, license, concession or other agreement for the use, occupancy or utilization of the Premises or any portion thereof, which provides for a rental or other payment for such use, occupancy or utilization based in whole or in part on the income or profits derived by any person or entity from the property leased, used, occupied or utilized. Any such purported lease, sublease, license, concession or other agreement shall be absolutely void and ineffective as a conveyance of any right or interest in the possession, use or occupancy of any part of the Premises. Any consent by Landlord hereunder shall not constitute a waiver of strict future compliance by Tenant with the provisions of this Article.

Notwithstanding the foregoing, without the consent and approval of Landlord, Tenant shall have the right to Transfer the Premises or any portion thereof without Landlord’s consent (however, Tenant shall endeavor to provide prior written notice thereof along with a true and complete copy of the sublease or assignment document) to (a) any Affiliate of Tenant, (b)any entity in which or with which Tenant, or its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions regarding merger and consolidation of corporations, or (c) any entity that acquires all or substantially all of Tenant’s assets or stock or all of the assets of an operating division of Tenant, and in any event shall notify Landlord in writing within thirty (30) days of the effective date of such assignment or sublease. For the purposes hereof, “Affiliate” means any person or entity that, directly or indirectly, controls, is controlled by or is under common control with Tenant. For purposes of this definition, "control" means possessing the power to direct or cause the direction of the management and policies of the entity by the ownership of a majority of the voting interests of the entity. Notwithstanding the foregoing, Landlord acknowledges that Tenant intends to allow individuals (or teams of individuals) working on projects with Tenant, Tenant’s business invitees and Tenant’s customers to temporarily use and occupy the Premises including, without limitation, employees of third party businesses whose co-location with Tenant at the Premises facilitates Tenant’s business operations or its ability to meet its obligations to customers (any of the foregoing herein call a “Permitted Occupant”). Provided that such use and occupancy is subject to all of the terms and conditions of this Lease and provided that (A) Tenant remains fully liable under this Lease; and (B) the occupancy arrangement is not a subterfuge by Tenant to avoid its obligations under this Article 20, then any such occupancy arrangement shall not be deemed a Transfer under this Section 20 nor be a violation of this Lease. None of the foregoing shall prohibit Tenant from recovering an equitable portion of its costs (including a pro rata portion of Tenant’s rental obligations) from any Permitted Occupant.

21. Default; Remedies; Damages, Bankruptcy of Tenant. Any one or more of the following events shall constitute an “Event of Default” hereunder, at Landlord’s election: (a) the sale of Tenant’s interest in the Premises under attachment, execution or similar legal process or, the adjudication of Tenant as a bankrupt or insolvent, unless such adjudication is vacated within thirty (30) days; (b) the filing of a voluntary petition proposing the adjudication of Tenant (or any guarantor of Tenant’s obligations hereunder) as a bankrupt or insolvent, or the reorganization of Tenant (or any such guarantor), or an arrangement by Tenant (or any such guarantor) with its creditors, whether pursuant to the Federal Bankruptcy Code or any similar federal or state proceeding, unless such petition is filed by a party other than Tenant (or any such guarantor) and is withdrawn or dismissed within thirty (30) days after the date of its filing; (c) the admission, in writing, by Tenant (or any such guarantor) of its inability to pay its debts when due; (d) the appointment of a receiver or trustee for the business or property of Tenant (or any such guarantor), unless such appointment is vacated within thirty (30) days of its entry; (e) the making by Tenant (or any such guarantor) of an assignment for the benefit of its creditors, or if, in any other manner, Tenant’s interest in this Lease shall pass to another by operation of law; (f) the failure of Tenant to pay any rent, additional rent or other sum of money when due and such failure continues for a period of ten (10) days after receipt of written notice that the same is past due hereunder;(g) if Tenant fails to pay any rent or additional rent when due after Landlord shall have given Tenant written notice with respect to such non-payment twice in any twelve (12) month period as provided in subsection (f) above; (h) Tenant shall fail to move into or take possession of the Premises within two hundred ten (210) days after the Rent Commencement Date; and (i) the default by Tenant in the performance or observance of any covenant or agreement of this Lease (other than a default involving the payment of money), which default is not cured within thirty (30) days after the giving of written notice thereof by Landlord, unless such default is of such nature that it cannot be cured within such thirty (30) day period, in which case no Event of Default shall occur so long as Tenant shall commence the curing of the default within such thirty (30) day period and shall thereafter diligently prosecute the curing of same.

Upon the occurrence and continuance of an Event of Default, Landlord, with such notice to Tenant as provided for by law or as expressly provided for herein, may do any one or more of the following: (a) perform, on behalf and at the expense of Tenant, any obligation of Tenant under this Lease which Tenant has failed to perform and of which Landlord shall have given Tenant written notice, the cost of which performance by Landlord, together, with interest thereon at the Default Rate, from the date of such expenditure, shall be deemed additional rent and shall be payable by Tenant to Landlord upon demand; (b) elect to terminate this Lease and the tenancy created hereby by giving notice of such election to Tenant in which event Tenant shall be liable for Base Rent, additional rent, and other indebtedness that otherwise would have been payable by Tenant during the remainder of the Term had there been no Event of Default, and on notice reenter the Premises, by summary proceedings or otherwise remove Tenant and all other persons and property from the Premises, and store such property in a public warehouse or elsewhere at the cost and for the account of Tenant, without resort to legal process and without Landlord being deemed guilty of trespass or becoming liable for any loss or damage occasioned thereby; and also, the right, but not the obligation, to re-let the Premises for any unexpired balance of the Term, and collect the rent therefor. In the event of such re‑letting by Landlord, the re-letting shall be on such terms, conditions and rental as Landlord may deem proper, and the proceeds that may be collected from the same, less the expense of re-letting (including reasonable leasing fees and commissions and reasonable costs of renovating the Premises), shall be applied upon Tenant’s rental obligation as set forth in this Lease for the unexpired portion of the Term. Tenant shall be liable for any balance that may be due under this Lease, although Tenant shall have no further right of possession of the Premises and Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished by reason of, any failure by Landlord to relet the Premises or any failure by Landlord to collect any rent due upon such reletting and (c) exercise any other legal or equitable right or remedy which it may have at law or in equity. Notwithstanding the provisions of clause (a) above and regardless of whether an Event of Default shall have occurred, Landlord may exercise the remedy described in clause (a) without any notice to Tenant if Landlord, in its good faith judgment, believes it would be materially injured by the failure to take rapid action, or if the unperformed obligation of Tenant constitutes an emergency.

TO THE EXTENT PERMITTED BY LAW, TENANT HEREBY EXPRESSLY WAIVES ANY AND ALL RIGHTS OF REDEMPTION, GRANTED BY OR UNDER ANY PRESENT OR FUTURE LAWS IN THE EVENT OF TENANT’S BEING EVICTED OR DISPOSSESSED FOR ANY CAUSE, OR IN THE EVENT OF LANDLORD’S OBTAINING POSSESSION OF THE PREMISES, BY REASON OF THE VIOLATION BY TENANT OF ANY OF THE COVENANTS AND CONDITIONS OF THIS LEASE, OR OTHERWISE. LANDLORD AND TENANT HEREBY EXPRESSLY WAIVE TRIAL BY JURY IN ANY ACTION OR PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER PARTY HERETO AGAINST THE OTHER PARTY ON ANY AND EVERY MATTER, DIRECTLY OR INDIRECTLY ARISING OUT OF OR WITH RESPECT TO THIS LEASE, INCLUDING, WITHOUT LIMITATION, THE RELATIONSHIP OF LANDLORD AND TENANT, THE USE AND OCCUPANCY BY TENANT OF THE PREMISES, ANY STATUTORY REMEDY AND/OR CLAIM OF INJURY OR DAMAGE REGARDING THIS LEASE.

Any reasonable costs and expenses incurred by Landlord (including, without limitation, reasonable attorneys' fees) in enforcing any of its rights or remedies under this Lease following an Event of Default, provided that Tenant shall not be obligated to pay such costs and expenses if it objects in writing to the validity of the Event of Default, shall be deemed to be additional rent and shall be repaid to Landlord by Tenant upon demand; and provided further that, if a formal adjudicatory matter is initiated and there is a final adjudicatory decision, the non-prevailing party shall pay the reasonable attorneys’ fees of the prevailing party.

Notwithstanding any of the other provisions of this Lease, in the event Tenant shall voluntarily or involuntarily come under the jurisdiction of the Federal Bankruptcy Code and thereafter Tenant or its trustee in bankruptcy, under the authority of and pursuant to applicable provisions thereof, shall have the power and so using same determine to assign this Lease, Tenant agrees that (i) Tenant or its trustee shall provide to Landlord sufficient information enabling it to independently determine whether Landlord will incur actual and substantial detriment by reason of such assignment and (ii) “adequate assurance of future performance” under this Lease, as that term is generally defined under the Federal Bankruptcy Code, shall be provided to Landlord by Tenant and its assignee as a condition of the assignment.

If this Lease is terminated by Landlord pursuant to this Section 21, Tenant shall, nevertheless, remain liable for all rent and damages which may be due or sustained prior to such termination, and all reasonable costs, fees and expenses including, but not limited to expenses incurred by Landlord in pursuit of its remedies hereunder, or in renting the Premises to others from time to time and additional damages (the "Liquidated Damages"), which shall be an amount equal to the total rent which, but for termination of this Lease, would have become due during the remainder of the Term, less the amount of rent, if any, which Landlord shall receive during such period from others to whom the Premises may be rented (other than any additional rent received by Landlord as a result of any failure of such other person to perform any of its obligations to Landlord), in which case such Liquidated Damages shall be computed and payable in monthly installments, in advance on the first day of each calendar month following termination of the Lease and continuing until the date on which the Term would have expired but for such termination, and any suit or action brought to collect any such Liquidated Damages for any month shall not in any manner prejudice the right of Landlord to collect any Liquidated Damages for any subsequent month by a similar proceeding.

If this Lease is terminated pursuant to this Section 21, Landlord may relet the Premises or any part thereof, alone or together with other premises, for such term(s) which may be greater or less than the period which otherwise would have constituted the balance of the Term and on such terms and conditions (which may include concessions, free rent and/or alterations of the Premises) as Landlord, in its sole discretion, may determine, but Landlord shall not be liable for, nor shall Tenant's obligations hereunder be diminished by reason of, any failure by Landlord to relet the Premises or any failure by Landlord to collect any rent due upon such reletting.

22. Landlord’s Default. If Landlord shall fail to perform any of the covenants or agreements in this Lease on the part of Landlord to be performed, and if the default shall continue for thirty (30) days (or such lesser reasonable period of time if emergency repairs or replacements are required) following written notice thereof from Tenant to Landlord to cure the specific default or defaults, in addition to all other remedies provided hereunder or now or hereafter afforded or provided by law or equity (which remedies shall be cumulative and non-exclusive), Tenant may at its election perform such covenant, agreement or work for or on behalf of the Landlord; provided, however, Tenant shall not have any cure rights if the default is not capable of being cured within thirty (30) days, but Landlord has commenced the cure within the thirty (30) day period and is diligently prosecuting the cure to completion. Any amount which Tenant shall advance in connection therewith shall be repaid by Landlord to Tenant, within twenty (20) days after written demand from Tenant, accompanied with reasonable supporting documentation, together with interest thereon at the Default Rate per annum from the date of such advance to the repayment thereof in full. If Landlord fails pay Tenant within the twenty (20) day period, Tenant shall only be permitted to offset the amount due against Annual Base Rent after obtaining a final, unappealable decision in its favor from an adjudicatory body. Notwithstanding anything to the contrary in the previous sentence, in an emergency, Tenant shall have the right to fulfill Landlord’s obligation on behalf of Landlord, after reasonable (in the circumstances) oral notice to Landlord at Landlord’s cost which cost shall be reimbursed by Landlord as set forth above.

23. Services and Utilities. Throughout the Term, Landlord shall maintain the Premises in a first-class manner consistent with Comparable Buildings, shall operate all Base Building Systems consistent with the Final Base Building Plans, and Landlord shall provide the following listed services and utilities, namely:

(a) heating, ventilation, and air conditioning (“HVAC”) for the 24 hours a day, seven days a week, as determined by Tenant pursuant to the computer-controlled system for the Building which, as long as Tenant leases the entire Building, will be under Tenant’s control ;

(b) electric energy in accordance with Section 24 following;

(c) automatic passenger elevator service 24 hours a day, seven days a week, in accordance with the Final Base Building Plans;

(d) evening, unescorted janitorial services to the Premises in accordance with the cleaning specifications attached as Exhibit “J”;

(e) hot and cold water sufficient for drinking, kitchen, lavatory toilet and ordinary cleaning purposes from fixtures either within the Premises all in accordance with the specifications contained within the Final Base Building Plans and the Construction Documents;

(f) replacement of ceiling tiles and all lighting tubes, lamp ballasts and bulbs in the Premises;

(g) extermination and pest control when and if necessary or at the request of Tenant; and

(h) maintenance of Common Areas in a manner consistent with other Comparable Buildings.

(i) landscaping, road and driveway repair and snow removal and maintenance of all improvements on the Property consistent with that found in Comparable Buildings;

(j) A controlled access security system for the Building permitting access thereto twenty-four (24) hours a day, three hundred sixty-five (365) days a year, via a Kastle or similar key-card system, including key-cards for such system; and

(k) Operational fire alarm and life safety systems (which, to the extent applicable, shall include telecommunications systems which are a part of such systems) in accordance with Applicable Laws and consistent with the Final Base Building Plans and the Construction Documents

Landlord reserves the right to stop service of the HVAC, elevator, plumbing and electric systems, when necessary, by reason of accident, or emergency, or for repairs, alterations, replacements, or improvements, which in the judgment of Landlord are desirable or necessary to be made, until the repairs, alterations, replacements, or improvements shall have been completed. Landlord shall have no responsibility or liability for failure to supply HVAC, elevator, plumbing, cleaning, and electric service, during the period when prevented from so doing by laws, orders, or regulations of any Federal, State, County or Municipal authority or by strikes, accidents or by any other cause whatsoever beyond Landlord’s control. Landlord’s obligations to supply HVAC are subject to applicable laws and regulations as to energy conservation and other such restrictions. In the event that Tenant should require supplemental HVAC for the Premises, any maintenance repair and/or replacement required for such supplemental service shall be performed by Landlord but the cost of such maintenance repair and/or replacement (including labor and materials) shall be paid by Tenant as additional rent. Notwithstanding the foregoing, in the event that any of the foregoing services are not provided by Landlord for a period of six (6) consecutive business days and such cessation is a result of Landlord's inaction or negligence, then Annual Base Rent and additional rent shall ▇▇▇▇▇ commencing on the seventh (7th) consecutive business day until such services are restored.

24. Electric Current. Landlord will supply the Premises with the necessary lines to provide electric service to the Premises for normal office and data center operations, as well as separate meters so that Tenant’s consumption of electric power can be separately measured and charged to Tenant all in accordance with the Final Base Building Plans. The power distribution to each floor of the Premises will be at a minimum of 2.5 ▇▇▇▇▇ for lighting and 4.5 ▇▇▇▇▇ available for convenience power. Tenant’s use of electrical energy in the Building shall not at any time exceed the capacity of any of the electrical conductors and equipment in or otherwise serving the Building, as set forth on Exhibit “I”. Commencing on the Commencement Date, Tenant shall pay all charges for electric and similar utilities or services so supplied directly to the utility company supplying same when due and before penalties or late charges on same shall accrue. Tenant, at Tenant’s expense, shall be responsible for contacting the utility company to secure an account in Tenant’s name as of the Commencement Date. Tenant shall not at any time overburden or exceed the capacity of the mains, feeders, ducts, conduits, or other facilities by which electric and similar utilities are supplied to, distributed in or serve the Premises. If Tenant desires to install any equipment which shall require additional electric or similar facilities of a greater capacity than as provided by Landlord, such installation shall be subject to Landlord’s prior written approval of Tenant’s plans and specifications therefor, which approval shall not be unreasonably withheld, conditioned or delayed. If such installation is approved by Landlord, all costs for providing such additional electrical and similar facilities shall be paid by Tenant.

25. Telephone and Telecommunications. Landlord shall arrange for the installation of telephone service by a provider acceptable to Tenant (the “Provider”) within the Building to the ground floor telephone utility closet and conduit to the ground floor telephone and electrical riser closets. Tenant shall be responsible for contacting the utility company supplying the telephone service and arranging to have such telephone facilities as it may desire to be extended and put into operation in the Premises, including without limitation, obtaining a low voltage permit for phone and data wiring. Tenant acknowledges and agrees that all telephone and telecommunications services desired by Tenant shall be ordered and utilized at the sole expense of Tenant. All costs related to installation and the provision of such service shall be borne and paid for directly by Tenant. Tenant shall obtain the requisite permit and complete the ceiling work in cooperation with Landlord in order not to interfere with or delay the completion of the Tenant Improvements by Landlord if Tenant elects to have Landlord complete the Tenant Improvements pursuant to Section 35, including, without limitation, the closing of the ceiling and the carpet installation, if applicable.

In the event Tenant wishes to utilize the services of a telephone or telecommunications provider other than the current provider, Tenant shall secure the prior written consent of Landlord before installing its lines or other equipment, which consent shall not be unreasonably withheld, conditioned or delayed. Prior to the commencement of any work in or about the Building by the alternate provider, the alternate provider shall agree to abide by such rules and regulations, job site rules, and such other requirements as reasonably determined by Landlord to be necessary to protect the interest of the Building and Property and Landlord, including, without limitation, providing security in such form and amount as reasonable determined by Landlord. Each alternate provider must be duly licensed, insured and reputable. Landlord shall incur no expense whatsoever with respect to any aspect of alternate provider’s provision of its services, including without limitation, the costs of installation, materials and service.

In addition, but only in the event that Tenant is no longer leasing the entire Building, Landlord reserves for itself and its successors and assigns the right, subject to Section 11.2 hereof, to install, operate, maintain, repair, replace and remove fiber optic cable and conduit and associated equipment and appurtenances within the Building and the Premises so as to provide telecommunications service to and for the benefit of tenants of the Building, if any.

26. Acceptance of Premises. Tenant shall have reasonable opportunity from time to time, provided it does not thereby interfere with the completion of Landlord’s Items, to examine the Premises prior to the Commencement Date to determine the condition thereof and progress of construction of the Base Building Shell and other of Landlord’s Items. Upon taking possession of the Premises of delivery of possession of Landlord’s Items, Tenant shall be deemed to have accepted same as being satisfactory and in the condition called for hereunder, except for latent defects and punch list items other items described in Section 35.

27. Inability to Perform. Subject to the provisions of this Lease, this Lease and the obligation of either party to its covenants and agreements hereunder shall in no way be affected, impaired or excused because of strikes or labor troubles or any outside cause whatsoever beyond such party’s control, including, but not limited to, governmental preemption in connection with a National Emergency, or by reason of any rule, order or regulation of any department or subdivision of any government agency or by reason of the conditions of supply and demand which have been or are affected by war or other emergency (“Unavoidable Delay”). Each party shall promptly notify the other of any Unavoidable Delay within twenty-five (25) days after the occurrence of the Unavoidable Delay which prevents such party from fulfilling any of its obligations under this Lease.

28. No Waivers. The failure of either party to insist, in any one or more instances, upon a strict performance of any of the covenants of this Lease, or to exercise any option herein contained, shall not be construed as a waiver, or a relinquishment for the future, of such covenant or option, but the same shall continue and remain in full force and effect. The receipt by Landlord of rent, with knowledge of the breach of any covenant hereof, shall not be deemed a waiver of such breach, and no waiver by Landlord of any provision hereof shall be deemed to have been made unless expressed in writing and signed by Landlord.

29. Access to Premises and Change in Services. Tenant shall have the right to designate all or any portion of the Building as "secure areas" to which access shall be restricted. Should Landlord desire to enter into and upon any "secure areas", Landlord shall so notify Tenant and Tenant shall make access to such portions of the Demised Premises available to Landlord within forty-eight (48) hours thereafter unless Tenant agrees otherwise. Notwithstanding anything to the contrary contained herein, Landlord shall be accompanied by an employee of Tenant in any "secure areas", and Landlord shall not unreasonably interfere with Tenant’s use of the Premises during any such entry. Notwithstanding the foregoing, in the event of an emergency, Landlord shall be permitted to enter any “secure areas” by any means necessary and Tenant shall reimburse Landlord for the costs of such entry within thirty (30) days after receipt of an invoice for such costs. Except as set forth above with respect to “secure areas,” Landlord shall have the right, without abatement of rent, provided Tenant’s use and enjoyment of the Premises is not interfered with more than a de minimus amount, to enter the Premises with at least forty-eight (48) hours advance notice, to examine the same, or to make such repairs and alterations as Landlord shall deem necessary for the safety and preservation of the Building, and also to exhibit the Premises to be let; provided, however, that in the case of emergency, no advance notice shall be required to be given to Tenant. Nothing herein contained, however, shall be deemed or construed to impose upon Landlord any obligation, responsibility or liability whatsoever, for the care, supervision or repair, of the Building or any part thereof, other than as herein elsewhere expressly provided. Landlord shall also have the right at any time, without the same constituting an actual or constructive eviction and without incurring any liability to Tenant therefor, to change the arrangement and/or location of entrances or passageways, doors and doorways, and corridors, stairs, toilets, elevators, or other public parts of the Building, and to change the name by which the Building is commonly known and/or its mailing address, provided that in no event shall Landlord exercise such rights without Tenant’s prior consent during the time that Tenant leases seventy-five percent (75%) or more of the Building unless Landlord is required to do so by a governmental authority. In no event shall any of the changes permitted in the immediately preceding sentence materially and adversely affect Tenant’s business operations in the Premises.

Except for the extent arising out of negligent or omission of Landlord or failure to exercise due care for Tenant’s property. Tenant hereby waives and releases any claim against Landlord or its agents or employees for damages for any injury or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby arising out of Landlord’s actions with this Section. For each of the aforesaid purposes, Landlord shall at all times have and retain a key with which to unlock all of the doors in, upon and about the Premises, excluding Tenant’s vaults, safes, files and “secure areas”, and Landlord shall have the right to use any and all means which Landlord may deem proper to open such doors in an emergency in order to obtain entry to the Premises, without liability to Tenant except for Landlord’s negligent act or omission and any failure to exercise due care for Tenant’s property. Any entry to the Premises obtained by Landlord in accordance with Section shall not

under any circumstances be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction of Tenant from the Premises or any portion thereof.

30. Estoppel Certificates. Tenant agrees, at any time and from time to time, upon not less than fifteen (15) days’ prior written request by Landlord, but not more frequently than twice in any twelve (12) month period, to execute, acknowledge and deliver to Landlord an estoppel certificate such reasonable form requested by Landlord and acceptable to Tenant which certifies that this Lease is unmodified and in full force, (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications) and the dates to which the rent and other charges have been paid in advance, if any, and stating whether or not to the knowledge of the signer of such certificate Landlord is in default in performance of any covenant, agreement or condition contained in this Lease and, if so, specifying each such default of which the signer may have knowledge, it being intended that any such statement delivered hereunder may be relied upon by third parties not a party to this Lease to whom the estoppel is addressed.

31. Subordination. Subject to the terms of this Section 31, Tenant accepts this Lease, and the tenancy created hereunder, subject and subordinate to any mortgages, overleases, leasehold mortgages or other security interests now or hereafter a lien upon or affecting the Building or the Property or any part thereof. (a “Mortgage”). Tenant shall, at any time hereafter, within fifteen (15) days after request from Landlord, execute a Subordination, Non-Disturbance Agreement (“SNDA”) in a reasonable form that may be required by any mortgage or mortgagee or overlandlord, provided that no SNDA shall increase Tenant’s payment obligations or other liability under this Lease or reduce Landlord’s obligations hereunder (herein a "Mortgagee") substantially in the form of Exhibit “K” hereto for the purpose of (a) subjecting or subordinating this Lease and the tenancy created hereunder to the lien of any such mortgage or mortgages or underlying lease, (b) affirming the agreement of the Mortgagee that so long as no Event of Default hereunder shall have occurred and be continuing, the leasehold estate granted to Tenant and the rights of Tenant pursuant to this Lease to quiet and peaceful possession of the Premises shall not be terminated, modified, affected or disturbed by any action which such Mortgagee may take to foreclose any such Mortgage, and (c) affirming the agreement of the Mortgagee and Tenant to attorn to each other as provided in Section 32 hereof. The failure of Tenant to execute any such instruments, releases or documents shall constitute a default hereunder. Notwithstanding the foregoing, as a condition to Tenant’s agreement hereunder to subordinate Tenant’s interest in this Lease to any Mortgage, Landlord shall first obtain an SNDA from such Mortgagee for the benefit of Tenant.

32. Attornment. Tenant agrees that upon any termination of Landlord’s interest in the Premises, Tenant shall, upon request, attorn to the person or organization then holding title to the reversion of the Premises (the “Successor”) and to all subsequent Successors, and shall pay to the Successor all of the rents and other monies required to be paid by Tenant hereunder and perform all of the other terms, covenants, conditions and obligations in this Lease contained; provided, however, that if in connection with such attornment Tenant shall so request from such Successor in writing, such Successor shall execute and deliver to Tenant an instrument wherein such Successor agrees that as long as an Event of Default does not exist under this Lease, Tenant's possession under the provisions of this Lease shall not be disturbed by such Successor.. In the event that the Mortgagee succeeds to the interest of Landlord hereunder and is advised by its counsel that all or any portion of the Annual Base Rent or additional rent payable by Tenant hereunder is or may be deemed to be unrelated business income within the meaning of the United States Internal Revenue Code or regulations issued thereunder, Mortgagee, as Landlord, shall have the right at any time, from time to time, to notify Tenant in writing of the required changes to the Lease. Tenant shall execute all documents necessary to effect any such amendment within ten (10) days after written request from Mortgagee, as landlord, provided that in no event shall such amendment increase Tenant’s payment obligations or other liability under this Lease or reduce Landlord’s obligations hereunder.

33. Notices. All notices and other communications to be made hereunder shall be in writing and shall be delivered to the addresses set forth below by any of the following means: (a) personal service or receipted courier service; (b) telecopying (if confirmed in writing sent by the methods specified in clauses (a), (c) or (d) of this Section), (c) registered or certified first class mail, return receipt requested, or (d) nationally-recognized overnight delivery service. Such addresses may be changed by notice to the other parties given in the same manner as provided above. Any notice or other communication sent pursuant to clauses(a) through (d) hereof shall be deemed received upon actual receipt or refusal thereof, provided if there is no record of actual

receipt of refusal thereof, any notice or other communication sent pursuant to clause (c) shall be deemed received five (5) days following deposit in the mail and/or if sent pursuant to subsection (d) shall be deemed received the next succeeding business day following deposit with such nationally recognized overnight delivery service. Such deemed receipt shall only apply if delivery at the applicable notice address was attempted.

35. . Tenant's Space.Landlord and Tenant acknowledge and agree that as of the date of this Lease, Tenant has not determined whether it will construct the Tenant’s Work (as defined herein) or whether it desires for Landlord to construct the Tenant’s Work. In order for Tenant to determine whether Landlord or Tenant will construct Tenant’s Work, the parties have agreed to the schedule set forth in Section 35.4.2 below so that the parties will have an agreed set of Construction Drawings (as hereinafter defined), in a condition suitable for Landlord and/or Tenant to solicit guaranteed maximum price bids for Tenant’s Work as of December 1, 2003. Tenant shall notify Landlord in writing on or before November 1, 2003, whether Tenant will requests Landlord to solicit a bid from Landlord’s general contractor which is constructing the Base Building Shell to construct Tenant’s Work (“Bid Request Notice”). Tenant shall notify Landlord in writing on or before that date which is fifteen (15) business days after Landlord provides its bid for Tenant’s Work (the “Election Notice”), if it elects for Landlord to construct the Tenant’s Work. If Tenant fails to send Landlord the Bid Request Notice or the Election Notice as required, Tenant shall be deemed to have elected to construct the Tenant’s Work itself, and the provisions of Sections 35.2 and 35.3 shall apply and none of the provisions of Section 35.4 shall apply. If Tenant sends the Election Notice as required, the provisions of Sections 35.4 shall govern the construction of Tenant’s Work. Sections 35.5 and 35.6 shall apply regardless of whether Landlord or Tenant constructs Tenant’s Work.

35.1 Construction of Landlord’s Items.

35.1.1 Landlord, at Landlord’s expense, shall construct a five (5) story building and parking lot, with a glass and pre-cast exterior, including building lobby, elevator lobbies on each of floors 2-5, restrooms and first floor corridors, all as required for a single-tenanted building, substantially in accordance with the guidelines which are entitled “Suburban Office Building Design Guidelines” dated January, 2003, which are attached hereto and made a part hereof as Exhibit “E” (referred to either as the “Base Building Shell” or the “Landlord’s Items”), and as more fully described in greater detail on Exhibit “C” and as depicted on the design drawings attached as Exhibit “A-2". In addition, Landlord, at Landlord’s expense, shall construct the Landlord’s Items, as described on Exhibit “C” attached hereto and made a part hereof. Landlord and Tenant hereby acknowledge and agree that prior to the execution of this Lease, Tenant requested Landlord to modify the building which had initially been planned by Landlord and such modifications have been incorporated in the Base Building Shell as outlined on Exhibit “L” attached hereto and made a part hereof (the “Modifications”). Landlord and Tenant shall cooperate with each other, negotiate in good faith and work as diligently as possible after the execution of this Lease to confirm the incremental cost savings or increases resulting from the each of the items comprising the Modifications. Upon mutual agreement of the net cost savings or increases, the parties shall enter into a written amendment to this Lease which establishes the net cost savings or increases. If there is a net cost savings, the amount of the Allowance shall be increased by the net cost savings and if there is a net cost increase, the amount of the Allowance shall be decreased by the by net cost increase. If for any reason Landlord and Tenant have not agreed on the net cost savings or cost increases on or before that date which is ten (10) business days after receipt of the written estimate from Landlord, Tenant shall be deemed to have accepted the net cost savings or cost increase as set forth in the estimate. Tenant acknowledges and agrees that notwithstanding any other provision of this Section 35 to the contrary, Tenant shall not be permitted to request any further modifications to the Base Building Shell prior to the date that Landlord obtains the grading permit and building permit for the Base Building Shell. See Section 35.5 regarding potential, future modifications to the Base Building Shell after the issuance of the grading permit and the building permit for the Base Building Shell.

Prior to the execution of this Lease, Landlord, at Landlord’s expense, delivered architectural floor plans for each of the floors of the Building in CAD format (“Landlord’s Floor Plans”) in sufficient detail for Tenant to prepare Space Plans, Design Development Drawings and Final Construction Drawings. When available, Landlord shall deliver to Tenant copies of all final plans and specifications for the Base Building Shell. Landlord shall be solely responsible for the development and preparation of the construction documents of all exterior areas, including, without limitation, appropriate grading, utility, landscaping and parking lot plans, and for obtaining all necessary local government and similar approvals for such documents and any necessary easements, licenses, permits and the like for all site work, which documents shall be deemed a part of the final plans and specifications for the Base Building Shell.

35.1.2 Landlord, at Landlord’s expense, shall complete the Landlord’s Items all in a good and workmanlike manner. Landlord covenants that completion of Landlord's Items shall be constructed in all material respects in accordance with the construction documents for the Base Building Shell which shall be substantially in accordance with the Design Drawings attached hereto as Exhibit “A-2” (“Base Building Construction Documents”) and shall be in accordance with applicable Federal, State and local rules, regulations, codes, laws and ordinances (including but not limited to zoning rules and regulations). Landlord warrants that the roof, HVAC system, windows and window seals, structural components and all electrical and plumbing systems and equipment serving the Base Building Shell (the “Base Building Systems”) shall be in good working order at the time of Delivery of Possession of Landlord’s Items, except to the extent that the completion of the such systems is dependent upon the completion of Tenant’s Work. Any change orders, construction change directives, or other modifications to the Base Building Construction Documents shall require Tenant’s prior approval if the Tenant’s Work is affected thereby, which approval shall not be unreasonably withheld, conditioned or delayed.

35.1.3 If Tenant does not request Landlord to complete the Tenant’s Work, Landlord shall use its reasonable efforts to achieve Delivery of Possession of Landlord’s Items (as defined herein) on or before that date which is twelve (12) months after the issuance of the shell building permit (the “Target Date”). Notwithstanding anything herein to the contrary, if the shell building permit is not issued on or before November 1, 2003, Tenant shall have the right to terminate this Lease by giving Landlord thirty (30) days’ advance written notice thereof, provided, however, that if the permit has been issued prior to the date of Tenant’s termination notice or during the thirty (30) day period, this Lease shall remain in full force and effect. The term "Delivery of Possession of Landlord’s Items" as used hereafter, shall be deemed to have occurred when (i) Landlord's Items shall have been substantially completed (as defined below) and Landlord’s contractors have vacated the Premises and removed all equipment, unused materials and debris, (ii) Landlord shall have made the Premises available to Tenant and ready for Tenant to obtain the appropriate governmental approvals to commence the Tenant’s Work (as defined below), including without limitation, final shell inspections and approvals, (iii) the parking areas, driveways, loading areas, infrastructure and utilities serving the Building and the Premises are complete and ready for use, and (iv) Landlord shall have given Tenant thirty (30) days’ prior written notice that the items in (i)-(iii), above, shall be satisfied as of the date of giving such notice. Landlord's Work shall be deemed to be “substantially completed” when (i) the Landlord's Items are completed such that the incomplete portions of Landlord's Items (i.e., the punchlist items) are such as shall not interfere with Tenant's ability to perform its work, install its fixtures and equipment and occupy the Premises; (ii) all means of access and all facilities necessary to Tenant's occupancy of the Premises, including without limitation, sidewalks, corridors, exterior doorways, at least two passenger elevators, one service elevator, stairways, toilets, base building HVAC, water, base building electric lighting and telephone service to the Building's main telephone room or as otherwise provided in the Base Building Shell Guidelines, have been properly installed and substantially completed (free of all scaffolding and construction materials)and are in good working order and are available to the Premises; (iii) all facilities and systems serving the Building or any part thereof have been completed, the exterior of the Building has been substantially completed and is completely enclosed and the remaining work in the Building is of such a nature as will not materially interfere with Tenant's construction of the Tenant’s Work; and (iv) final shell inspections and approvals(or equivalent approval from the applicable governmental agencies) with respect to the Base Building Shell have been received and copies delivered to Tenant.

35.1.4 If Delivery of Possession of Landlord’s Items has not occurred on or before the Target Date, subject to extension for Force Majeure Events as herein defined, Landlord shall pay Tenant liquidated damages (by means of a credit against Annual Base Rent and additional rent first becoming due) in an amount which is equal to (i) the daily amount of Base Rent due hereunder until the Delivery of Possession of Landlord’s Items actually occurs for the first forty-five (45) days of the delay and (ii) twice the daily amount of Base Rent due hereunder until the Delivery of Possession of Landlord’s Items actually occurs commencing on the forty-sixth (46^th) day of delay, if applicable. Not later than ninety (90) days prior to the Target Date or at any time prior to such date upon Landlord becoming aware of a probable delay, Landlord shall notify Tenant in writing of any anticipated delay in the Delivery of Possession of Landlord’s Items.

35.1.5 The Delivery of Possession of Landlord’s Items shall be confirmed by a written punchlist prepared by Landlord’s architect within five (5) business days after the Delivery of Possession of Landlord’s Items (confirmed by a walkthrough with Tenant’s architect and Tenant), which shall also set forth the Base Building work remaining to be performed (the “Base Building Punchlist”) so that the requirements of the Base Building Construction Document will be fully satisfied, which Base Building Punchlist shall be subject to approval by Tenant. Within sixty (60) days after the Delivery of Possession of Landlord’s Items, Landlord shall complete all items identified in the Base Building Punchlist. Landlord, at its expense, shall promptly correct all defects in design, materials and workmanship in the Base Building Shell for which Tenant sends notice within twelve (12) months after the Date of Delivery of Landlord’s Items. If Landlord fails to meet a material obligation of this Section 35.1.5, and (a) Tenant provides written notice of such failure, and (b) Landlord fails to fulfill such obligation within thirty (30) days after receipt of Tenant’s notice of such failure, then Tenant shall have the right to fulfill such obligation on behalf of Landlord, the cost of which shall be paid by Landlord promptly following demand therefore; provided however, that Landlord’s cure period shall be extended where the failure is not reasonably curable within thirty (30) days after written notice and Landlord uses good faith efforts and works diligently and continuously to fulfill its obligations.

35.1.6 Tenant and Tenant’s architect shall have the right to review, at Tenant’s expense, the prosecution of the work contemplated by the Base Building Construction Documents, and upon reasonable prior notice Landlord shall allow Tenant and Tenant’s architect access to the Property for such reviews, provided such access and reviews do not unreasonably interfere with or delay the completion of the Base Building Shell. Landlord shall furnish such information as may be reasonably necessary or pertinent for effectively reviewing the completion of the Base Building Shell. The exercise of such rights of review and access by Tenant or Tenant’s architect shall not relieve Landlord of any of its obligations pursuant to this Lease and shall not be construed as acceptance by Tenant or by Tenant’s architect of all or any portion of the Landlord’s Items. Tenant shall have the right to attend and observe all testing and commissioning of Base Building Systems and to receive copies of all reports generated in connection therewith. Landlord shall give Tenant reasonable prior notice of all testing and commissioning.

35.1.7 Landlord shall regularly consult with and inform Tenant of the construction schedules for construction of the Base Building Shell and the progress of the Base Building Shell (and, if Landlord supervises the construction of the Tenant’s Work, the Tenant’s Work).

35.2 Construction of Tenant’s Work.

35.2.1 As used herein, the term “Tenant’s Work” shall refer to all desired improvements to the Premises other than the Landlord’s Items. Tenant, at Tenant’s expense, shall submit to Landlord, for Landlord's approval, Tenant's space plan for the Premises and all subsequent related design drawings and construction drawings in accordance with the provisions of Section 35.4 below.

35.2.2 Intentionally Left Blank.

35.2.3 In the event that Tenant does not elect to have Landlord construct Tenant’s Work, Landlord shall provide Tenant with a reasonable amount of construction management services in connection with the construction of both Landlord’s Work and Tenant’s Work for a construction management fee in the amount of two percent (2%) of the hard and soft costs to complete the Tenant’s Work (the “Management Fee”), which fee shall not exceed One Hundred Thousand Dollars ($100,000.00). Such construction management services shall include, without limitation, (i) review and approval of Tenant’s construction drawings and coordination of the completion of Landlord’s Work, (ii) coordination of Tenant’s access to the Building including the parking areas and rear entrances, loading dock, one (1) service elevator and the stairwells during construction of Tenant’s Work, (iii) overview of the installation of Tenant’s telecommunication equipment, (iv) confirmation that Tenant’s security/alarm system and fire alarm system is consistent with the system installed by Landlord in the Building, (v) coordination with the Base Building security during construction, (vi) coordination of all noise related work in an occupied Building (i.e., tie in to fire alarm and sprinkler systems, hammer-drilling, core drilling during non-business hours), and (vii) location of dumpster. In the event Tenant elects to have Landlord construct the Tenant’s Work, Tenant shall have no obligation to pay the Management Fee described in this Section 35.2.3 and Landlord’s sole compensation in connection with the Tenant’s Work shall be as set forth in Section 35.4.

35.2.4 Unless Tenant elects to have Landlord construct the Tenant’s Work, in which case it shall be Landlord’s obligation, Tenant shall apply to the governmental authorities having jurisdiction there over for any building permit which shall be required in connection with the construction, installations or alterations designated as Tenant’s Work. Landlord shall cooperate with Tenant to facilitate the issuance of the building permit for Tenant’s Work. Landlord agrees that Tenant may apply for its permit simultaneously with its delivery to Landlord of the Construction Drawings for Landlord’s approval.

35.2.5 From and after Delivery of Possession of Landlord’s Items, upon prior approval from Tenant, Landlord may re-enter the Premises to complete any portion of Landlord's Work which has not yet been completed, provided that the same does not materially interfere with the scheduling or performance of the Tenant’s Work. During the period of such re-entry, Landlord shall not unreasonably interfere with the construction of any of the Tenant’s Work. Landlord shall be liable for and indemnify and hold Tenant harmless against any injury or damage resulting from or arising out of Landlord’s construction activities on or within the Building or Property after Delivery of Possession of Landlord’s Items, excepting acts of gross negligence or misconduct caused by Tenant’s agents, contractors, representatives and/or employees. After the Delivery of Possession and issuance of the permit for Tenant’s Work, Tenant shall, at its sole cost and expense, complete Tenant’s Work and the installation of Tenant's furniture, fixtures and equipment, provided that (i) Landlord and Tenant shall have agreed on the Approved Plans and Specifications, (ii) Tenant shall have delivered to Landlord a copy of the building permit for Tenant’s Work, and (iii) Tenant shall have deposited with Landlord the policies or certificates of insurance required under the terms of this Lease, including without limitation, the contractor’s insurance policy which names Landlord and Landlord’s mortgagee as additional insureds. Tenant covenants that completion of Tenant's Work shall be in accordance with applicable Federal, State and local rules, regulations, codes, laws and ordinances (including but not limited to zoning rules and regulations).

In addition, in the event Tenant does not elect to have Landlord construct the Tenant’s Work, prior to commencement of construction of the Tenant’s Work, Tenant shall deliver to Landlord the names (and other information as may reasonably be requested by Landlord) of those duly qualified licensed contractors who will be performing the Tenant’s Work on behalf of Tenant, which contractors shall be subject to Landlord's prior approval (such approval not to be unreasonably withheld, conditioned or delayed). All work to be performed on or within the Premises by Tenant pursuant to the terms of this Section 35 shall be performed only by those contractors, subcontractors and tradespeople licensed to do business in the State of Maryland and approved by Landlord as aforesaid and shall be performed in accordance with the Interior Construction and Renovation Requirements, a copy of which is attached hereto as Exhibit “C-1”. Tenant shall be liable for and indemnify and hold Landlord harmless against damage to the Premises, and the Building and Landlord's other improvements resulting from or arising out of Tenant's construction activities on or within the Premises, excepting the acts of negligence and misconduct caused by Landlord's agents, contractors, representatives and/or employees. Tenant shall cause the improvements to the Premises to be constructed in a good and workmanlike manner and in accordance with the Approved Plans and Specifications (as defined in Section 35.4.2(f) hereof). Landlord shall not require Tenant to employ any particular subcontractors with respect to any particular trade for Tenant’s Work.

Unless Tenant elects to have Landlord construct the Tenant’s Work, commencing on the Delivery of Possession of Landlord’s Items, (i) Tenant shall pay any charges for hoisting, Tenant’s use of electrical services and water and Tenant shall establish an account in its own name directly with the utility company providing such electrical services and water prior to the commencement of Tenant’s Work, (ii) Tenant shall be provided adequate parking spaces and elevators during construction at no additional cost, and (iii) Tenant, at Tenant’s expense, shall protect all Base Building areas that have completed finishes.

Notwithstanding anything in this Section 35 to the contrary, Tenant, at Tenant’s expense, shall engage Corporate Cooling & Controls, LLC (“CCC”) to make any changes required to the HVAC control system. In addition, Tenant shall coordinate the installation and location of any supplemental HVAC equipment with Landlord to coordinate roof penetration concerns and maintain the validity of all existing roof warranties.

If Landlord or Landlord’s agents, contractors, representatives or employees interfere with Tenant’s ability to substantially complete the Tenant’s Work in any manner, including, but not limited to, by requiring a cessation of Tenant’s Work or as a result of defects in the completion of the Landlord’s Items, the Rent Commencement Date shall be delayed for a period of time which is equal to the length of Landlord’s delay.

35.3 Disbursement of Allowance.

35.3.1 If Tenant is responsible for construction of the Tenant’s Work, the Allowance and the Amortized Amount, if any, shall be disbursed to Tenant on a progress payment basis. Proper draw requests submitted by the 20th day of any calendar month shall be paid by the 15th day of the following calendar month. Each of Landlord’s progress payments shall be limited to an amount equal to the aggregate amounts theretofore paid by Tenant (as certified by Tenant’s architect) to Tenant’s contractors, subcontractors, material suppliers, and vendors, and which have not been subject to previous disbursements from the Allowance. Tenant shall withhold from its general contractor, and shall require its general contractor to withhold from each subcontractor, a retainage equal to ten percent (10%) of each progress payment made until the Tenant’s Work is fifty percent (50%) complete, and thereafter no further incremental retainage shall be required if the work is being satisfactorily prosecuted. Tenant shall, upon Landlord’s request, provide adequate evidence of such retainage, and in the event that Tenant fails to provide such evidence, then Landlord may withhold an amount equal to the retainage described above. All requests for disbursement of the Allowance and the Amortized Amount (as defined herein), if any, shall be accompanied by certificate signed by Tenant or Tenant’s architect (a) that the sum then requested was paid by Tenant to contractors, subcontractors, materialmen, engineers and other persons who have rendered services or furnished materials in connection with work on the Tenant Work, (b) a complete description of such services and materials and the amounts paid or to be paid to each of such persons in respect thereof, and (c) that the work described in the certificate has been completed substantially in accordance with the Approved Plans and Specifications and (ii) paid receipts or such other proof of payment as Landlord shall reasonably require for all such work completed.

35.3.2 If any of the Allowance is not paid pursuant to subsection (a) above, it shall be paid by Landlord to Tenant upon completion of the Tenant's Work, to reimburse Tenant for amounts actually paid by Tenant in connection therewith to Tenant's vendors, suppliers or contractors, provided that Landlord shall have received (i) a certificate in accordance with the requirements of subsection (a) above, accompanied by lien waivers satisfactory to Landlord executed by any contractors or subcontractors for whose labor or material Tenant has previously been reimbursed pursuant to subsection (a) above, (ii) paid receipts or such other proof of payment as Landlord shall reasonably require evidencing that final payment has been made for all materials and labor furnished in connection with the Tenant Work, and (iii) a copy of a final unconditional certificate of occupancy evidencing that Tenant may commence occupancy of the Premises for all purposes set forth in this Lease.

35.3.3 Tenant shall be permitted to apply the Allowance and the Amortized Amount, if any, to any costs associated with the design and construction of the Tenant’s Work and Tenant’s relocation to the Premises, including without limitation, the Tenant’s Work, space planning and design, mechanical, electrical and plumbing engineering costs, construction fees, tenant improvement cabling, voice/data, phone data costs, built-in and removable furniture, consultant fees, any move or relocation costs and Tenant-initiated and Landlord-approved changes to the Base Building Shell.

35.3.4 If the cost to complete the Tenant’s Work exceeds the Allowance, Landlord shall advance up to the Amortized Amount, subject to the provisions of Section 35.3.4.1. Tenant shall notify Landlord whether it desires Landlord to advance all or any portion of the Amortized Amount; provided that Tenant shall have no obligation to notify Landlord of its desire to utilize the Amortized Amount prior to delivery of Possession of Landlord’s Items.. Such portion of the Amortized Amount which has been advanced shall be repaid by Tenant to Landlord on a monthly basis, together with Base Rent, as additional rent, in an amount equal to the amount of the Amortized Amount which has been advanced, amortized over the ten (10) year term, with interest accruing at ten percent (10%) per annum. Tenant shall execute an amendment to this Lease or an acknowledgment of the Amortized Amount within fifteen (15) days after receipt of a written statement from Landlord, together with reasonable supporting documentation. Notwithstanding that the Amortized Amount shall be payable as additional rent, it shall be treated and accounted for separately from other rent payable under this Lease as it will not be subject to any annual or other rental escalation. Notwithstanding anything herein to the contrary, accrual of interest on the Amortized Amount shall not commence until the date same (or any portion thereof) is disbursed.

35.3.4.1 Notwithstanding anything in Section 35.3.4 to the contrary, Landlord shall not be required to disburse any portion of the Amortized Amount if Tenant’s credit rating falls below a “BB-“ as determined by Standard & Poor’s credit rating agency or ▇▇▇▇▇’▇ credit rating agency. If, after disbursing all or any portion of the Amortized Amount, Tenant’s credit rating falls below a “B+“ as determined by Standard & Poor’s credit rating agency or ▇▇▇▇▇’▇ credit rating agency, Tenant shall repay the unamortized amount of the Amortized Amount upon fifteen (15) days advance written notice from Landlord.

35.3.4.2 If Tenant does not elect to utilize the Amortized Amount within six (6) months after the Rent Commencement Date, then Tenant shall be deemed to have waived its right to utilize the Amortized Amount.

35.3.5 If Tenant does not fully utilize the Allowance, Tenant shall be permitted to take a credit against Base Rent in the amount of the unused Allowance, provided that Tenant utilizes that credit during the first twenty-four (24) months of the Term.

35.3.6 Notwithstanding anything in this Section 35.3 to the contrary, Landlord shall only be required to disburse the Allowance and the Amortized Amount on a per square foot basis as Tenant elects to improve the Premises. By way of example, but without limitation, if Tenant determines to improve only 75,000 rentable square feet of the Premises initially, Landlord shall only be required to disburse $1,650,000 of the Allowance (computed as $22 multiplied by 75,000 rsf) and $750,000 of the Amortized Amount (computed as $10 multiplied by 75,000 rsf), provided that the other conditions for disbursement have been satisfied.

35.4 Tenant’s Right to Request Landlord to Construct Tenant's Work.

35.4.1 If Tenant elects for Landlord to construct Tenant’s Work, the term “Landlord’s Work” shall then refer to Landlord’s Items and Tenant’s Work.

35.4.2 In order to accommodate Tenant’s desired occupancy of the Premises and to permit both Landlord and Tenant to solicit bids for the Tenant’s Work in accordance with the first paragraph of this Section 35, Landlord and Tenant agree to the following schedule for performance of their respective responsibilities hereunder:

NOTE: If Tenant desires to have Landlord prepare a bid for constructing the Tenant’s Work, then Tenant is required to notify Landlord no later than November 1, 2003.

d. 10 business days after receipt of

Design Development Drawings Landlord to advise Tenant of Design Development Drawings approval or note why Drawings were not approved and Tenant to revise accordingly. See note at end of this schedule regarding long lead items.

After approval by the parties and the permitting authority, the Construction Drawings to be referred to as the “Approved Plans and Specifications” (provided, however, that if change orders are subsequently approved by the parties pursuant to the provisions of this Section 35, the term “Approved Plans and Specifications” shall include the initial approved Construction Drawings, as modified by the approved change orders.

NOTE: If Tenant elects to construct the Tenant’s Work itself, the balance of this Schedule is not applicable and the provisions of Sections 35.1, 35.2, 35.3, 35.5 and 35.6 shall govern the construction of the Tenant’s Work and Tenant shall apply for the Tenant Improvement permit with ▇▇▇▇ Arundel County.

If Tenant has requested for Landlord to construct the Tenant’s Work, Landlord shall apply for the Tenant Improvement permit with ▇▇▇▇ Arundel County within two (2) days after receipt of Tenant’s Election Notice and shall thereafter diligently prosecute the issuance of all necessary permits for the Tenant’s Work. I

g. November 1, 2004 Substantial Completion of the Premises and Delivery of Possession of the Premises by Landlord to Tenant, subject to extension for Force Majeure Events as described herein (“Landlord’s Work Target Date”). Landlord’s Work Target Date shall be extended for delays arising from Force Majeure Events, but only with respect to Force Majeure Events occurring after the commencement of construction of the Base Building Shell, as hereinafter defined.

If either party is required to resubmit any of its deliveries hereunder, the submitting and reviewing party, as applicable, shall have five (5) business days to resubmit and review, respectively.

All consents and approvals required from Landlord under this Section 35 shall not be unreasonably withheld, conditioned or delayed; further, Landlord’s consent or approval shall be deemed granted if Landlord has not responded (giving reasonable detail for the reasons for denial of consent or approval) within any specified time period for response stated herein. Notwithstanding the foregoing, any objection to a requested consent or approval shall be for good cause, which shall be limited to the following: (i) adverse impact to the structural integrity of the Building or Base Building Systems, (ii) adverse impact on the Building’s exterior, (iii) lack of compliance with Applicable Laws, and/or (iv) design materially inconsistent with the designs of comparable buildings in the National Business Park (e.g., 201, 211 and 221 National Business Park) and Tenant does not agree to restore the Building to a condition consistent with comparable buildings in National Business Park at the end of the Term. Landlord's approval of the Space Plan, Design Drawings and the Construction Documents for Tenant's Work shall create no responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with all laws, rules, and regulations of governmental agencies or authorities.

Note: Upon the receipt of the Design Development Drawings described in Section 35.4.2(c) above, Landlord shall reasonably advise Tenant in writing whether any of the specifications involve a long lead item and Tenant shall have five (5) business days after receipt of Landlord’s notice to advise Landlord whether (i) Tenant shall modify such specification to not require such long lead item, or (ii) Tenant shall continue to require such long lead item, with the recognition that arrival and installation of the long lead item may delay “substantial completion” of Landlord’s Work (as defined in Section 35.4.5). If Tenant elects option (ii) above in the immediately preceding sentence regarding long lead items, and Landlord can substantiate that Landlord was actually delayed in the completion of Landlord’s Work as a result of delays in delivery of long lead items, then notwithstanding the incomplete nature of the long lead item, “substantial completion” of the Landlord’s Work, as defined in Section 35.4.5, shall be deemed to occur upon completion of all other items of Landlord’s Work and the occurrence of all other conditions set forth in Section 35.4.5 which are not affected by the long lead item, even if a certificate of occupancy or other governmental approvals has not been issued based on the incomplete nature of the long lead item, provided, Landlord shall in any case diligently and in good faith pursue substantial completion of Landlord’s Work.

If either party believes that the other party has failed to meet any deadline set forth above, it shall notify the other party within twenty-five (25) business days after the date of the failure in order to collect liquidated damages or pursue its rights as described in Section 35.4.3 below.

Notwithstanding anything set forth on the foregoing schedule to the contrary, if Landlord has in all material respects complied in a timely manner with its obligations to provide Landlord’s Floor Plans and other obligations under subsections (b), (d) and (f) and has timely applied for and diligently prosecuted the issuance of the permit to construct the Tenant’s Work and such permit is not issued by March 1, 2004, the Landlord’s Work Target Date shall be extended on a day for day basis for each day of delay beyond March 1, 2004, until the permit is issued.

35.4.3 Landlord, at Landlord’s expense, shall complete the Landlord’s Work, all in accordance with the Approved Plans and Specifications in a good and workmanlike manner. Landlord covenants that completion of Landlord's Work shall be in accordance with applicable Federal, State and local rules, regulations, codes, laws and ordinances (including but not limited to zoning rules and regulations). If Tenant requests Landlord to construct the Tenant’s Work, Landlord shall hold bi‑weekly meetings to discuss the progress of the Landlord’s Items. Landlord shall schedule such meetings at more frequent intervals when needed, or upon the reasonable request of Tenant.

35.4.4 Any alterations, modifications or deviations to the final Approved Plans and Specifications requested by Tenant shall be made in the form of a written change order(s) prepared at Tenant's sole cost and expense, which costs shall include, but not be limited to, the engineering fees incurred by Landlord (but as part of Tenant’s Work Costs) and if made after the “Change Order Date” (as hereinafter defined), shall be subject to the prior approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. The costs of work performed by Landlord pursuant to Tenant's approved written change orders shall include all net increases in costs of labor and materials plus if such change order is requested after the Change Order Date, an amount equal to five percent (5%) of the net increase in hard costs for overhead and profit. As used herein, the term “Change Order Date” means the date on which Landlord commences construction of the Tenant’s Work. At Tenant's request, Landlord shall fully cooperate with Tenant to establish such costs or estimates thereof in advance of performing the work.

35.4.5 If Landlord fails to Deliver Possession of the Premises with the Landlord’s Work substantially completed (as defined herein) on or before the Landlord’s Work Target Date, subject to extension for Force Majeure Events, Landlord and Tenant agree that the damages to Tenant would be difficult to ascertain and, therefore, as Tenant’s sole remedy hereunder, Landlord agrees to pay Tenant a liquidated damages sum (by means of a credit against Annual Base Rent and additional rent first becoming due) equal to (i) the daily Base Rent due hereunder until the Delivery of Possession of Landlord’s Work actually occurs for the first forty-five (45) days of the delay, and (ii) twice the daily amount of Base Rent due hereunder until the Delivery of Possession of Landlord’s Work actually occurs commencing on the forty-sixth (46^th) day of delay, if applicable. Not later than ninety (90) days prior to the Landlord’s Work Target Date or at any time prior to such date upon Landlord becoming aware of a probable delay, Landlord shall notify Tenant in writing of any anticipated delay in the Delivery of Possession of Landlord’s Work. The term "Delivery of Possession” as used herein, shall be deemed to have occurred when (i) Landlord's Work shall have been substantially completed (as defined below) and Landlord’s contractors have vacated the Premises, and (ii) Landlord shall have notified Tenant that the Premises are substantially completed. Landlord shall use its reasonable efforts to give Tenant at least fifteen (15) days’ advance notice that the Landlord’s Work will be substantially completed. Landlord's Work shall be deemed to be “substantially completed” when (i) the Landlord's Work are completed such that the incomplete portions of Landlord's Work (i.e., the punchlist items) are such as shall not interfere with Tenant's ability to install its furniture, fixtures and equipment; (ii) all facilities and systems serving the Building and Premises have been completed, the exterior of the Building has been substantially completed and is completely enclosed and the remaining work in the Building (outside the Premises) is of such a nature as will not materially interfere with Tenant’s occupancy of the Premises, and (iii) Landlord has obtained and delivered to Tenant an unconditional certificate of use and occupancy or equivalent approval from the applicable governmental agencies with respect to the Premises and Tenant’s Work, the interior and exterior Common Areas and Base Building Shell. Landlord shall keep Tenant advised of the status of substantial completion of Landlord’s Work. Notwithstanding the foregoing, the requirements of subsection (iii) shall be deemed satisfied if all of the other subsections have been satisfied and the government approval is delayed as a result of the installation of furniture, fixtures or equipment which is not included within the scope of Landlord’s Work. The Delivery of Possession of Landlord’s Work shall be confirmed by a written punchlist prepared by Landlord’s architect within five (5) business days after the Delivery of Possession of Landlord’s Work (confirmed by a walkthrough with Tenant’s architect and Tenant), which shall also set forth the Landlord’s Work remaining to be performed (the “Landlord’s Work Punchlist”) so that the requirements of the Approved Plans and Specifications will be fully satisfied, which Landlord’s Work Punchlist shall be subject to approval by Tenant. Within sixty (60) days after the Delivery of Possession of Landlord’s Work, Landlord shall complete all items identified in the Landlord’s Work Punchlist. Landlord, at its expense, shall promptly correct all defects in design, materials and workmanship in the Landlord’s Work for which Tenant sends notice within twelve (12) months after the Date of Delivery of Landlord’s Work. If Landlord fails to meet a material obligation of this paragraph, and (a) Tenant provides written notice of such failure, and (b) Landlord fails to fulfill such obligation within thirty (30) days after receipt of Tenant’s notice of such failure, then Tenant shall have the right to fulfill such obligation on behalf of Landlord, the cost of which shall be paid by Landlord promptly following demand therefore; provided however, that Landlord’s cure period shall be extended where the failure is not reasonably curable within thirty (30) days after written notice and Landlord uses good faith efforts and works diligently and continuously to fulfill its obligations.

For the purposes of this paragraph, the term “Tenant Net Delay” shall refer to the number of days, if any, that Tenant has (i) delayed in fulfilling its obligations under subsections (a), (c), and (e) of Section 35.4.2 (i.e., taking into account both time delays and time savings from required dates); the term “Landlord Delay” shall refer to the number of days, if any, that Landlord has delayed in fulfilling its obligation under subsections (b), (d), (f) of Section 35.4.2; the term “Total Delay” shall refer to the Tenant Net Delay reduced by the Landlord Delay. Notwithstanding anything herein to the contrary, if the Total Delay is in excess of five (5) days but less than sixty (60) days, the date of Delivery of Possession of Landlord’s Work (and correspondingly, the Commencement Date) shall be deemed to be the date of the actual date of Delivery of Possession of Landlord’s Work backdated by the Total Delay. If, however, Landlord and Tenant agree on the Approved Plans and Specifications as required by Section 35.4.2(f) on or before December 1, 2003, regardless of the amount of Total Delay, or in the event Landlord is unable to substantiate that Landlord was actually and materially delayed in completing Landlord’s Work as a result of the Tenant Net Delay as aforesaid, then in either such case this paragraph shall be of no further force or effect. Notwithstanding the immediately preceding sentence, if the Total Delay exceeds sixty (60) days, regardless of the status of agreement on the Approved Plans and Specifications, the Delivery of Possession of Landlord’s Work shall be deemed to be the earlier of (i) November 1, 2004, or (ii) the actual date of Delivery of Possession of Landlord’s Work. By way of example, but without limitation, assume Tenant Net Delay is 12 days and Landlord Delay is 2 days, (i) if Landlord and Tenant agree on the Approved Plans and Specifications on November 30, 2003, the Delivery of Possession of Landlord’s Work shall be the actual date; however, if Landlord and Tenant agree on the Approved Plans and Specifications after November 30, 2003 and the actual date of Delivery of Possession of Landlord’s Work occurs on November 11, 2004, the Commencement Date will be deemed to be November 1, 2004 after taking into account the Total Delay of ten (10) days.

35.4.6 Cost of Tenant’s Work.

35.4.6.1 The term “Tenant’s Work Costs” shall refer to the actual costs of constructing the Tenant’s Work (including reimbursable items, such as permit fees, prints, telephone, mileage and postage); and a construction management fee of five percent (5%) based solely on hard costs for work performed by Landlord or its contractors, including without limitation, permitting costs; and other costs as herein described in this Section, which fee Landlord shall deduct from the Allowance and the Amortized Amount pro rata as amounts are disbursed therefrom to pay hard costs of construction and, after the Allowance and the Amortized Amount are exhausted, the balance of such fee shall be paid by Tenant.

35.4.6.2 If the amount of Tenant’s Work Costs exceed the Allowance, Landlord, at Tenant’s option, upon written request from Tenant, shall advance an additional amount not to exceed the Amortized Amount. Such portion of the Amortized Amount which has been advanced shall be repaid by Tenant to Landlord on a monthly basis, in equal installments, together with Base Rent, as additional rent, but without any escalations, in an amount equal to the amount of the Amortized Amount which has been advanced, amortized over a ten (10) year term, with interest accruing at ten percent (10%) per annum. Tenant shall execute an amendment to this Lease or an acknowledgment of the Amortized Amount within fifteen (15) days after receipt of a written statement from Landlord, together with reasonable supporting documentation. Any Tenant’s Work Costs incurred by Landlord in excess of the difference between Thirty-Two Dollars ($32.00) per rentable square foot (which is the sum of the Allowance and the Amortized Amount) and the disbursements made to Tenant in accordance with Section 35.4.6.2, shall be paid by Tenant to Landlord within thirty (30) days after receipt of a written invoice, together with reasonable supporting documentation.

35.5 Modifications to Base Building Shell. Regardless of whether Tenant constructs Tenant’s Work or elects for Landlord to construct Tenant’s Work, if Tenant requests Landlord to make a change to the Base Building Shell after the issuance of the grading permit and the building permit for the Base Building Shell, Landlord shall promptly notify Tenant in writing whether it approves such change and if so, in reasonable detail of the additional or incremental cost to make such change and the change to the Target Date or to Landlord’s Work Target Date, as applicable (“Landlord’s Response Notice”). In no event shall Landlord be required to approve a change(s) which would result in an aggregate delay (when combined with other requested modifications to the Base Building) of more than sixty (60) days in the Target Date or the Landlord’s Work Target Date. Tenant shall have five (5) business days after receipt of Landlord’s notice to advise Landlord whether (i) Tenant shall modify such specification to not require such Base Building Shell, or (ii) Tenant shall continue to require such Base Building Shell modification, with the recognition that the modification to the Base Building Shell may delay Delivery of Possession (“Tenant’s Modification Notice”). If Tenant accepts the terms set forth in the Landlord’s Response Notice in a timely fashion, Landlord and Tenant shall mutually execute an acknowledgment or amendment to this Lease which sets forth the revised Target Date or Landlord’s Work Target Date, as applicable, and the credit to be given to Tenant or additional costs to be paid by Tenant, as the case may be, in accordance with the provisions of this Section 35.5.

If the change requested by Tenant causes an increase in costs, whether or not it will also cause a delay in the Target Date or the Landlord’s Work Target Date, Landlord shall not be obligated to approve the change unless Tenant agrees, in writing, to pay or reimburse Landlord for the increased cost of the Base Building Work caused by the change, based on a firm price from Landlord. The increased cost caused by any change shall be reasonably detailed and supported by reasonably complete and sufficient backup documentation. To the extent that a change requested by Tenant results in a decrease in the cost to complete the Base Building Shell, the amount of such decrease shall be paid by Landlord to Tenant in the form of a dollar‑for‑dollar increase in the Allowance. To the extent that a change results in an increase cost to complete the Base Building Shell, at Tenant’s sole election, either Tenant shall pay cash therefore or, the Allowance shall be decreased on a dollar‑for‑dollar basis. Tenant shall advise Landlord of its payment election simultaneously with Tenant’s Modification Notice and if Tenant elects to pay cash therefore, Tenant shall pay such amount within thirty (30) days after the date of Tenant’s Modification Notice.

If the change requested by Tenant will cause a delay in the Target Date or the Landlord’s Work Target Date, as applicable, Landlord shall not be obligated to approve the change unless Tenant agrees, in writing, that such delay shall not postpone or defer the Rent Commencement Date and that the Rent Commencement Date shall occur on the day when it would otherwise have occurred if such change had not been made as determined in accordance with the immediately succeeding sentence. To determine the Rent Commencement Date that would have occurred, the parties acknowledge that (i) Landlord will be required to complete the Landlord’s Item or the Landlord’s Work, as applicable, (ii) determine the actual date of Delivery of Possession of Landlord’s Items or the Delivery of Possession of Landlord’s Work, as applicable (in either case, referred to as the “Actual Delivery Date”) and then (iii) backdate the Rent Commencement Date from the Actual Delivery Date by the number of days set forth in Landlord’s Response Notice as the additional time required to complete the modification. By way of example, but without limitation, Tenant has requested a modification to the Base Building Shell which Landlord advises Tenant will delay the Delivery of Possession of Landlord’s Items by 21 days and the Actual Delivery Date is June 22, 2004, then the Rent Commencement Date shall be deemed to be June 1, 2004.

If the change requested by Tenant will cause a delay in the Target Date or the Landlord’s Work Target Date, as applicable, Landlord shall not be obligated to approve a change unless Tenant agrees, in writing, that the Target Date and the Landlord’s Work Target Date, as applicable, shall be equitably adjusted to accommodate the additional time required to make the change.

35.6 Definition of “Force Majeure Events”. As used in this Section 35, the term “Force Majeure Events” shall refer to events which delay or prevent either party from constructing, making any repairs, rebuilding or restoring, or furnishing any construction services or performing any other construction covenant or duty (as compared to obtaining issuance of the permit for Base Building Shell, Landlord’s Items or Tenant’s Work), whether express herein or implied, to be performed by such party due to strike, lockout, weather, embargo, war, governmental orders or acts of God. If either party claims a Force Majeure Event has occurred, it shall notify the other party in writing within twenty-five (25) days after the occurrence of such event.

36. Quiet Enjoyment. Tenant, upon the payment of rent and the performance of all the terms of this Lease, shall at all times during the Term peaceably and quietly enjoy the Premises without any disturbance from Landlord or any other person claiming through Landlord.

37. Vacation of Premises. Tenant shall vacate the Premises at the end of the Term. Subject to the provisions of this Section 35, if Tenant fails to vacate within five (5) days after the end of the term there shall be payable to Landlord an amount equal to one hundred fifty percent (150%) of the monthly Annual Base Rent stated in Section 1.1.6 paid immediately prior to the holding over period for each month or part of a month that Tenant holds over, plus all other payments provided for herein, and the payment and acceptance of such payments shall not constitute an extension or renewal of this Lease. In event of any such holdover, Landlord shall also be entitled to all remedies provided by law for the speedy eviction of tenants, and to the payment of all reasonable attorneys’ fees and expenses incurred in connection therewith. Notwithstanding the foregoing, if (i) Tenant delivers notice to Landlord at least twelve (12) months prior to the expiration of the Term setting forth its intent to hold over for a fixed period of time not to exceed twelve (12) months, and (ii) Landlord has not already executed and delivered a lease for all or a part of the Premises to a new tenant (a “New Tenant”), and (iii) an Event of Default is not continuing as of the date of its notice or at the expiration of the Term, then Tenant may remain in the Premises for the period set forth in its notice so long as Tenant pays as a monthly Rent equal to one hundred ten percent (110%) of the Annual Base Rent payable under this Lease for the last full calendar month of the Term plus all other payments provided for herein. If Tenant holds over beyond the period set forth in its notice the first two sentences of this Section 37 shall apply. Upon request by Tenant, Landlord shall inform Tenant whether or not Landlord has executed leases for all or part of the Premises and the terms of such leases to the extent the same affect Tenant’s ability to holdover after the end of the term.

38. Members’ Liability. It is understood that the Owner of the Building is a Maryland limited liability company. All obligations of the Owner hereunder are limited to the net assets of the Owner from time to time, including insurance proceeds and other proceeds from the Property. No member of Owner, or of any successor partnership, whether now or hereafter a member, shall have any personal responsibility or liability for the obligations of Owner hereunder. Landlord agrees during the Term of this Lease that it shall not accept financing secured solely by the Premises with a loan-to-value ratio of greater than ninety percent (90%) as of the date of the loan; provided, however, that Landlord may accept financing with a loan-to-value ratio of greater than ninety percent (90%) if simultaneously with the disbursement of the loan proceeds Landlord provides to Tenant an irrevocable letter of credit from an issuer and in form and substance reasonably acceptable to Tenant in the amount of two million dollars ($2,000,000) to secure Landlord’s obligations under this Lease.

39. Separability. If any term or provision of this Lease or the application thereof to any person or circumstances shall, to any extent, be invalid or unenforceable, the remainder of this Lease or the application of such term or provision of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law.

40. Indemnification.

40.1 Tenant’s Indemnification. Except to the extent arising out of the negligent act or omission of Landlord, Tenant shall indemnify and hold harmless Landlord and all of its and their respective members, partners, directors, officers, agents and employees from any and all liability, loss, cost or expense arising from all third-party claims resulting from or in connection with any act, omission or negligence of Tenant or any of its subtenants or licensees or its or their partners, directors, officers, agents, employees, invitees or contractors; and together with all costs and expenses reasonably incurred or paid in connection with each such claim or action or proceeding brought thereon, including, without limitation, all reasonable attorney’s fees and expenses.

In case any action or proceeding is brought against Landlord and/or any of its and their respective partners, directors, officers, agents or employees and such claim is a claim from which Tenant is obligated to indemnify Landlord pursuant to this Section, Tenant, upon written notice from Landlord shall resist and defend such action or proceeding (by counsel reasonably satisfactory to Landlord). The obligations of Tenant under this Section shall survive termination of this Lease for one (1) year.

40.2 Landlord’s Indemnification. Except to the extent arising out of the negligent act of omission of Tenant, Landlord shall indemnify and hold harmless Tenant and all of its and their respective members, partners, directors, officers, agents and employees from any and all liability, loss, cost or expense arising from all third-party claims resulting from or in connection with any act, omission or negligence of Landlord or any of its subtenants or licensees or its or their partners, directors, officers, agents, employees, invitees or contractors, together with all costs and expenses reasonably incurred or paid in connection with each such claim or action or proceeding brought thereon, including, without limitation, all reasonable attorney’s fees and expenses.

In case any action or proceeding is brought against Tenant and/or any of its and their respective partners, directors, officers, agents or employees and such claim is a claim from which Landlord is obligated to indemnify Tenant pursuant to this Section, Landlord, upon written notice from Tenant shall resist and defend such action or proceeding (by counsel reasonably satisfactory to Tenant). The obligations of Landlord under this Section shall survive termination of this Lease for one (1) year.

41. Captions. All headings anywhere contained in this Lease are intended for convenience or reference only and are not to be deemed or taken as a summary of the provisions to which they pertain or as a construction thereof.

42. Brokers. Tenant represents that Tenant has dealt directly with, only with, the Broker as defined in Section 1.1.14 as broker in connection with this Lease, and Tenant warrants that no other broker negotiated this Lease or is entitled to any commissions in connection with this Lease. Landlord agrees to pay, in consideration for the brokerage services rendered by Broker, a brokerage commission equal to three percent (3%) of the gross rental value of this Lease (as more fully described in the separate commission agreement) paid by Tenant over the Initial Term, pursuant to a separate agreement between Landlord and Broker.

NBP 220, LLC, Landlord

and THE TITAN CORPORATION, Tenant

Form of Subordination, Non-Disturbance and Attornment Agreement

SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT

Note: This Subordination, Non-Disturbance and Attornment Agreement results

in your leasehold estate in the Property becoming subject to and of lower priority

than the lien of some other or later security instrument.

THIS AGREEMENT is entered into by and amongTHE TITAN CORPORATION (“Tenant”), NBP 220, LLC (“Landlord”), and INSERT LENDER (“Beneficiary”).

R E C I T A L S:

A. Tenant has entered into a lease (the “Lease”) covering a portion of the real property described on Exhibit A hereto (the “Property”). The Lease and the premises leased thereunder are more particularly described on Exhibit B hereto (the “Premises”).

B. Pursuant to that certain ___________________dated as of _____________________, 200_, as amended, from time to time, Beneficiary and certain other financial institutions that are or may become parties to such agreements (collectively “Lenders”) have made or agreed to make a loan and to extend certain other financial accommodations (collectively the “Loan”) to an entity of which Landlord is a subsidiary, CORPORATE OFFICE PROPERTIES, L.P., a Delaware limited partnership, and to certain of its subsidiaries. The Loan is evidenced by promissory notes (collectively, as amended, the “Notes”), which Notes are or will be secured by a mortgage or deed of trust in favor of Beneficiary covering the Property (the “Mortgage”).

C. In order to induce Beneficiary to make the Loan and to maintain the financial accommodations extended thereunder, the parties hereto have agreed to subordinate the Lease to the lien of the Mortgage on the terms set forth in this Agreement. In order to induce Tenant to execute and deliver this Agreement, Beneficiary has agreed not to disturb Tenant’s possession of the Premises under certain circumstances set forth herein.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Subordination. Notwithstanding anything to the contrary set forth in the Lease, the Lease and the leasehold estate created thereby and all of Tenant’s rights thereunder shall be and shall at all times remain subject, subordinate and inferior to the Mortgage and the lien thereof, and all rights of Beneficiary thereunder and to any and all renewals, modifications, consolidations, replacements and extensions thereof.

2. Acknowledgments and Agreements by Tenant. Tenant and Beneficiary acknowledge and agree that:

2.1. Landlord has executed and delivered to Beneficiary a Mortgage, including an assignment of the Lease and the rents thereunder, and certain other agreements evidencing and securing the Loan. Tenant hereby recognizes and agrees to honor such assignment of the Lease and rents thereunder. If Beneficiary notifies Tenant in writing of a default under the Mortgage and demands that Tenant pay its rent and all other sums due under the Lease to the Beneficiary, Tenant shall honor such written demand and pay its rent and all other sums due under the Lease directly to Beneficiary or as otherwise required pursuant to such notice. Beneficiary hereby releases Tenant and shall indemnify, defend and hold harmless Tenant from and against any losses, liabilities, claims or causes of action Tenant may suffer as a result of compliance with Beneficiary’s notice.

2.2. Tenant shall send a copy of any notice or statement required to be delivered under the Lease to Beneficiary at the same time such notice or statement is sent to Landlord, in the manner specified in this Agreement.

2.3. In the event of any act or omission by Landlord which would give Tenant the right, either immediately or after the lapse of time, to terminate the Lease or to claim a partial or total eviction, Tenant will not exercise any such right until:

2.3.1 it has given written notice of such act or omission to Beneficiary; and

2.3.2. the same period of time as is given to Landlord under the Lease to cure such act or omission shall have elapsed following such giving of notice to Beneficiary.

If Beneficiary cannot cure Landlord’s breach or default by Landlord under the Lease and provided that such breach does not result in Tenant being unable to conduct its normal business operations in the Premises, the period for Beneficiary to cure Landlord’s act or omission shall be extended for so long as Beneficiary is diligently pursuing such cure, but not longer than one hundred twenty days.

2.4. Tenant has no right or option to purchase the Premises or the Property, or any portion thereof or any interest therein. To the extent that Tenant hereafter acquires any such right or option to purchase the Premises or the Property, the same is hereby acknowledged to be subject and subordinate to the Mortgage and is hereby waived and released as against Beneficiary except to the extent Beneficiary agrees in writing to the contrary.

2.5. Beneficiary, in making any disbursements to Landlord, is under no obligation or duty to oversee or direct the application of the proceeds of such disbursements, and such proceeds may be used by Landlord for purposes other than improvement of the Property.

2.6. This Agreement satisfies any condition or requirement in the Lease relating to the grant of a non-disturbance agreement by Beneficiary.

3. Foreclosure. In the event of foreclosure of the Mortgage, or upon a transfer of the Property by conveyance in lieu of foreclosure, then:

3.1. So long as Tenant is not in default under the terms, covenants or conditions of the Lease or this Agreement (beyond the expiration of any applicable notice and cure periods), Tenant’s occupancy of the Premises shall continue, undisturbed on the terms and conditions contained in the Lease for the balance of the term of the Lease. Tenant shall attorn to and accept any successor owner of the Building as landlord under the Lease, and be bound by and perform all of the obligations imposed by the Lease, and any successor owner of the Property will not disturb the possession of Tenant, and will be bound by all of the obligations imposed on the Landlord by the Lease. Any purchaser at a foreclosure sale, by deed in lieu thereof, or any other successor owner of the Property shall not be:

3.1.1. liable for any act or omission of a prior landlord (including Landlord), except for defaults of a continuing nature which continue after the date Beneficiary acquires title to the Property by foreclosure or conveyance in lieu of foreclosure; or

3.1.2. subject to any offsets or defenses which Tenant might have against any prior landlord (including Landlord), except those that relate to defaults of a continuing nature which continue after the date Beneficiary acquires title to the Property by foreclosure or conveyance in lieu of foreclosure; or

3.1.3. bound by any rent or additional rent which Tenant might have paid in advance to any prior landlord (including Landlord) for a period in excess of one month or any security deposit or other prepaid charge which Tenant might have paid in advance to any prior landlord (including Landlord) other than the security deposit, and then only to the extent actually turned over to such successor owner; or

3.1.4. bound by any material agreement or material modification of the Lease made without the written consent of Beneficiary which consent shall not be unreasonably withheld, conditioned or delayed.

3.2. Upon the written request of either Beneficiary or Tenant to the other given following any foreclosure or conveyance in lieu thereof, the parties agree to execute a lease of the Premises upon the same terms and conditions as the Lease between Landlord and Tenant which lease shall cover any unexpired term of the Lease existing prior to such foreclosure or conveyance in lieu of foreclosure.

4. Acknowledgments and Agreements by Landlord. Landlord, as landlord under the Lease and mortgagor under the Mortgage, acknowledges and agrees for itself and its heirs, successors and assigns that:

4.1. This Agreement does not waive any of Beneficiary’s rights under the Mortgage, or in any modify or release Landlord from its obligations to comply with the Mortgage;

4.2. The Mortgage remains unmodified and in full force and effect; and

4.3. Landlord hereby irrevocably directs Tenant to recognize and honor Landlord’s assignment to Beneficiary of the Lease and the rents thereunder. If Beneficiary notifies Tenant in writing of a default under the Mortgage and demands that Tenant pay its rent and all other sums due under the Lease to Beneficiary, Landlord hereby irrevocably directs Tenant to honor such written demand and pay its rent and all other sums due under the Lease directly to Beneficiary or as otherwise required pursuant to such notice. Landlord hereby releases Tenant and shall indemnify, defend and hold harmless Tenant from and against any losses, liabilities, claims or causes of action Tenant may suffer as a result of compliance with Beneficiary’s notice. Tenant shall be under no duty to controvert or challenge any notice from Beneficiary and Tenant's compliance with any notice shall not be deemed to violate the Lease. Landlord shall look solely to Beneficiary with respect to any claims Landlord may have on account of an incorrect or wrongful notice. Tenant shall be entitled to full credit under the Lease for any rent paid to Beneficiary pursuant to a notice to the same extent as if such rent were paid directly to Landlord.

5. Obligations of Beneficiary. Beneficiary shall have no obligation or incur any liability with respect to the erection or completion of the improvements in which the Premises are located or for completion of the Premises or any improvements for Tenant’s use and occupancy. Anything herein or in the Lease to the contrary notwithstanding, no successor owner of the Property shall have any obligation, or incur any liability, beyond the then existing interest, if any, of the Purchaser in the Property and Tenant shall look exclusively to such interest of the Purchaser, if any, in the Property for the payment and discharge of any obligations imposed upon the Purchaser hereunder or under the Lease, and the Purchaser is hereby released and relieved of any other liability hereunder and under the Lease. As regards the Purchaser, Tenant shall look solely to the estate or interest owned by the Purchaser in the Property and Tenant will not collect or attempt to collect any such judgment out of any other assets of the Purchaser. Nothing contained in this Section impairs, limits or otherwise modifies the obligations of Landlord to Tenant under the Lease.

6. No Merger. Landlord, Tenant and Beneficiary agree that unless Beneficiary otherwise consents in writing, Landlord’s estate in and to the Property and the leasehold estate created by the Lease shall not merge but shall remain separate and distinct, notwithstanding the union of the estates either in Landlord or Tenant or any third party by purchase, assignment or otherwise.

7. Notice. All notices and other communications to be made hereunder shall be in writing and shall be delivered to the addresses set forth below by any of the following means: (a) personal service or receipted courier service; (b) telecopying (if confirmed in writing sent by the methods specified in clauses (a), (c) or (d) of this Section), (c) registered or certified first class mail, return receipt requested, or (d) nationally-recognized overnight delivery service.

MODIFICATIONS TO BASE BUILDING

NBP 220 Design Modifications to Shell Base Building

The following is a list of design and construction modifications to the NBP 220 shell building requested by Titan Corporation (Titan). The items identify above standard revisions to the original base building design and construction and were developed during several design review meetings with Titan and their architect, ▇▇▇▇ ▇▇▇▇. In addition, we also identified various credits to Titan for items normally installed as a part of the base building that Titan has elected to complete as a part of their tenant work. The costs associated with these modifications will be developed and submitted to Titan for their review within the next few weeks.

Scope additions to base building:

1. Recess slab on grade 4'- 4" to accommodate 200+ person auditorium on the first floor.

Costs to include design and engineering (architectural, structural, MEP) and construction, lowered footings, longer and/or heavier steel columns, retaining walls and foundations, piers, excavation and haul off of material, drain tile, and waterproofing. In addition, provisions will be made to provide space and support for a supplemental HVAC unit on the roof.

2. Service Area/ Loading Dock relocation from northwest to northeast side of the building.

Costs to include architectural redesign of first floor core plan that includes the relocation of the restrooms, elevators, corridors, and service rooms as well as civil redesign of the loading dock and parking areas.

3. Addition of a rear building entrance.

Costs to include the design, engineering, and construction of a rear building entrance with double doors and a vestibule. Additional sidewalks will be added to access the building.

4. Parking increase from 600 to 700+ spaces.

Costs to include civil redesign of site plan to add 100+ additional parking spaces above base building standard of 4 spaces per 1000sf of space. This revision also changed the site access off Carina Road and increased the required area for storm water retention areas directly proportional to the hard surface area increase. Construction costs will include the 100+ additional spaces, associated curb and gutter, additional site concrete (sidewalks), storm water utilities and the increase in storm water management requirements.

NBP 220 Design Modifications to Shell Base Building

5. Design and installation of new restroom/shower room facility

Costs to include the design and construction of a new restroom/shower room that incorporates Titan's desire for a shower facility that also provides the additional fixtures required by the auditorium use. Two restrooms, with 3 fixtures and 2 lavatories each, as well as 2 shower rooms with 3 showers and 18 half sized lockers each will be installed and finished. Construction costs will include the walls, ceilings, finishes, fixtures, plumbing and mechanical systems. HVAC will be a part of the core roof top unit.

6. Site modifications.

Costs to include the design and construction of a patio area, with furniture, to be located at the rear entrance to the facility.

7. Secured ductbank. [Lined out and initialed]

8. Back-up generator

Costs to include the installation of below grade conduits from the main electric room to a predetermined location 5' outside the building to allow for future installation of a generator.

9. Upgrade of building main electrical service.

Costs to include the design and installation of upgraded main electric service to the facility. Current base building design calls for a 3000A service. Titan stated they might require an increase in this service to accommodate their tenant requirements. Titan is to provide a request for this service (if desired) during the next month.

10. Exterior wall SCIF modifications.

COPT is currently working with Titan to modify the exterior wall detail normally provided with a shell base building to incorporate several design and construction provisions that provide for SCIF level security. Costs to include the design and construction of this above standard installation.

NBP 220 Design Modifications to Shell Base Building

Credits to base building construction:

Titan has notified COPT that they would like to install finishes in various areas of the base building to integrate with their tenant design. In addition, Titan requested that some areas of the building not be finished in order to avoid rework due to damage from tenant construction or demolition. The following is a list of the base building areas and the level of finishes to be provided.

1. COPT will provide finishes in the following areas as part of the shell building construction: mechanical room, main telephone room, main electrical room, all restrooms, janitor closets, all telephone/electric rooms (2 per floor), three elevators, elevator machine room, and front and rear vestibules. Since these rooms will have all finishes provided, there is_ no credit to Titan.

2. Titan has requested that the following areas not be finished to avoid damage during tenant build-out: egress corridors, loading dock corridor, the three stairwells, and the restroom vestibules on each floor. These areas will have drywall, ceiling grid, ceiling tile, sprinklers, and lights, etc. installed as a part of the base building. The drywall will be spackled and ready for paint (since the stairwell walls are masonry they will be pointed up and prime coated) and the tile will be installed under the water fountains. Titan will receive a credit for paint and flooring not completed.

3. Titan has requested that the following areas not be built out as part of the base building: main entrance lobby on the first floor, elevator lobbies on all floors, and first floor tenant corridors. Titan will be given a credit for all work deleted from these areas. Items include framing and drywall, painting, flooring, lights, ceilings, wall finishes, etc. The credit will be based on the level of finishes currently in NBP 201.

4. Titan has requested that all the building interior columns on all floors not be framed and drywalled (with the exception of the wet stacks). Titan will receive a credit for not installing, taping and spackling the drywall.
