It is expressly understood, acknowledged and agreed by Sublessee that all of the other terms, conditions and covenants of this Sublease shall be those stated in the Master Lease except as excluded in Section 4.b herein, modified as appropriate in the circumstances so as to make such Articles, and any Sections contained therein. Sublessee shall be subject to, bound by and comply with all of said Articles and 4 Sections of the Master Lease with respect to the Premises and shall satisfy all applicable terms and conditions of the Master Lease relating to the Premises for the benefit of both Sublessor and Landlord, it being understood and agreed that wherever in the Master Lease the word "Tenant" appears, for the purposes of this Sublease, the word "Sublessee" shall be substituted, and wherever the word "Landlord" appears, for the purposes of this Sublease, the word "Sublessor" shall be substituted; and that upon the breach of any of said terms, conditions or covenants of the Master Lease by Sublessee or upon the failure of Sublessee to pay Rent or comply with any of the provisions of this Sublease, Sublessor may exercise any and all rights and remedies granted to Landlord by the Master Lease.

Time for Notice. The time limits provided for in the provisions of the Master Lease for the giving of notice, making of demands, performance of any act, condition or covenant, or the exercise of any right, remedy or option, are amended for the purposes of this Sublease by lengthening or shortening the same in each instance by five (5) days, as appropriate, so that notices may be given, demands made, or any act, condition or covenant performed, or any right, remedy or option hereunder exercised, by Sublessor or Sublessee, as the case may be, within the time limit relating thereto contained in the Master Lease. If the Master Lease allows only five (5) days or less for Sublessor to perform any act, or to undertake to perform such act, or to correct any failure relating to the Premises or this Sublease, then Sublessee shall nevertheless be 5 allowed three (3) days to perform such act, undertake such act and/or correct such failure. 5. Landlord's Obligations. It shall be the obligation of Landlord to (i) provide all services to be provided by Landlord under the terms of the Master Lease and (ii) to satisfy all obligations and covenants of Landlord made in the Master Lease. Sublessee acknowledges that Sublessor shall be under no obligation to provide any such services or satisfy any such obligations or covenants; provided, however, Sublessor, upon written notice by Sublessee, shall diligently attempt to enforce all obligations of Landlord under the Master Lease. 6. Rent. a. Base Rent. Upon execution hereof, Sublessee shall deliver the first month's Base Rent to Sublessor, to be applied against Sublessee's first obligation to pay Base Rent hereunder. Sublessee shall pay to Sublessor the Base Rent in advance on the first day of each month of the Term, commencing the Phase I Commencement Date without being invoiced by Sublessor. In the event the first day of the Term shall not be the first day of a calendar month or the last day of the Term is not the last day of the calendar month, the Base Rent shall be appropriately prorated based on a thirty (30) day month. All installments of Base Rent shall be delivered to Sublessor's Address, or at such other place as may be designated in writing from time to time by Sublessor, in lawful money of the United States and without deduction or offset for any cause whatsoever. b. Net Rental. Sublessee shall be responsible for Sublessee's Proportionate share of all costs and expenses of every kind and nature which may be imposed, at any time, on Sublessor pursuant to the Master Lease (except for Base Rent, as defined in the Master Lease) including, but not limited to, additional rent, Operating Expenses, Utilities and Real Estate Taxes, all as defined in the Master Lease. As hereinafter used, "Rent" shall include Base Rent and all additional charges to be paid by Sublessee pursuant to this Section 6.b. 7. Security Deposit. Upon execution hereof, Sublessee shall deposit the Security Deposit with Sublessor. The Security Deposit shall secure Sublessee's obligations under this Sublease to pay Base Rent and other monetary amounts, to maintain the Premises and repair damages thereto, to surrender the Premises to Sublessor in clean condition and repair upon termination of this Sublease and to discharge Sublessee's other obligations hereunder. Sublessor may use and commingle the Security Deposit with other funds of Sublessor. If Sublessee fails to perform Sublessee's obligations hereunder, Sublessor may, but without any obligation to do so, apply all or any portion of the Security Deposit towards fulfillment of Sublessee's unperformed obligations. If Sublessor does so apply 6 any portion of the Security Deposit, Sublessee's failure to remit to Sublessor a sufficient amount in cash to restore the Security Deposit to the original amount within five (5) days after receipt of Sublessor's written demand to do so shall constitute an event of default. Upon termination of this Sublease, if Sublessee has then performed all of Sublessee's obligations hereunder, Sublessor shall return the Security Deposit, or whatever amount remains of the Security Deposit after Sublessor applied all or a portion of the Security Deposit to perform Sublessee's obligations hereunder, to Sublessee without payment of interest. 8. Damage and Destruction. a. Termination of Master Lease. If the Premises is damaged or destroyed and Landlord or Sublessor exercises any option either may have to terminate the Master Lease, if any, this Sublease shall terminate as of the date of the termination of the Master Lease. b. Continuation of Sublease. If the Master Lease is not terminated following any damage or destruction as provided above, this Sublease shall remain in full force and effect and Sublessee shall be entitled to any reduction or abatement of Base Rent in an amount in proportion to the corresponding reduction in base rent for the Premises which Sublessor receives under the Master Lease. 9. Eminent Domain. a. Total Condemnation. If all of the Premises is condemned by eminent domain, inversely condemned or sold in lieu of condemnation, for any public or a quasi-public use or purpose ("Condemned" or "Condemnation") , this Sublease shall terminate as of the date of title vesting in such proceeding, and Base Rent shall be adjusted to the date of termination. b. Partial Condemnation. If any portion of the Premises is Condemned, and Sublessor exercises any option to terminate the Master Lease, this Sublease shall automatically terminate as of the date of the termination of the Master Lease. If Sublessor has the option to terminate the Master Lease, Sublessor shall promptly give Sublessee notice of such option and shall exercise such option if so directed by Sublessee subject to the relevant provisions of the Master Lease and further provided that such partial condemnation renders the Premises unusable for Sublessee's business, as reasonably determined by Sublessor. If this Sublease is not terminated following any such Condemnation; this Sublease shall remain in full force and effect. Sublessor shall diligently enforce any rights under the Master Lease to require Lessor to rebuild the Premises. Base Rent shall be equitably adjusted to take into account interference with 7 Sublessee's ability to conduct its operations on the Premises as a result of the Premises being Condemned. c. Sublessee's Award. Subject to the provisions of the Master Lease, Sublessee shall have the right to recover from the condemning authority, but not from Sublessor, such compensation as may be separately awarded to Sublessee in connection with costs and removing Sublessee's merchandise, furniture, fixtures, leasehold improvements and equipment to a new location. 10. Insurance. All insurance policies required to be carried by Sublessee, pursuant to the Master Lease, shall contain a provision whereby Sublessor and Landlord are each named as additional insureds under such policies. 11. Brokerage Commission. Sublessor shall pay a brokerage commission to Broker for Sublessee's subletting of the Premises as provided for in a separate agreement between Sublessor and Broker. Sublessee warrants for the benefit of Sublessor that its sole contact with Sublessor or the Premises in connection with this transaction has been directly with Sublessor and Broker. Sublessee further warrants for the benefit of Sub-lessor that no other broker or finder can properly claim a right to a commission or a finder's fee based upon contacts between the claimant and Sublessee with respect to the other party or the Premises. Sublessee shall indemnify, defend by counsel acceptable to Sublessor and hold Sublessor harmless from and against any loss, cost or expense, including, but not limited to, attorneys' fees and court costs, resulting from any claim for a fee or commission by any broker or finder, other than any claims by Broker, in connection with the Premises and this Sublease. 12. Sublessee's Indemnity. Sublessee shall defend, indemnify and hold harmless Sublessor, its partners, employees, and agents, and Landlord, from and against any and all claims, liabilities, suits, judgments, awards, damages, losses, fines, penalties, costs and expenses, including reasonable attorney's fees, that Sublessor its partners, employees and agents, and Landlord may suffer, incur or be liable for by reason of or arising out of or related to the breach by Sublessee of any of the duties, obligations, liabilities or covenants applicable to Sublessee hereunder, Sublessee's occupancy or use of the Premises, any alterations, additions or modifications made to the Premises by Sublessee or Sublessee's negligence or willful misconduct. This indemnification shall survive termination of this Sublease. 13. Right to Cure Sublessee's Defaults. If Sublessee shall at any time fail to make any payment or perform any other obligation of Sublessee hereunder, then Sublessor shall have the right, but not the obligation, after the lesser of five (5) days' 8 notice to Sublessee or the time within which Landlord may act on Sublessor's behalf under the Master Lease, or without notice to Sublessee in the case of any emergency, and without waiving or releasing Sublessee from any obligations of Sublessee hereunder, to make such payment or perform such other obligation of Sublessee in such manner and to such extent as Sublessor shall deem necessary, and in exercising any such right, to pay any incidental costs and expenses, employ attorneys and other professionals, and incur and pay attorneys' fees and other costs reasonably required in connection therewith. Sublessee shall pay to Sublessor upon demand all sums so paid by Sublessor and all incidental costs and expenses of Sublessor in connection therewith, together with interest thereon at the Interest Rate described in the Master Lease. 14. Miscellaneous. a. Entire Agreement. This Sublease contains all of the covenants, conditions and agreements between the parties concerning the Premises, and shall supersede all prior correspondence, agreements and understandings concerning the Premises, both oral and written. No addition or modification of any term or provision of this Sublease shall be effective unless set forth in writing and signed by both Sublessor and Sublessee. b. Captions. All captions and headings in this Sublease are for the purposes of reference and convenience and shall not limit or expand the provisions of this Sublease. c. Landlord's Consent. This Sublease is conditioned upon Landlord's written approval of this Sublease within fifteen (15) business days after the Effective Date. If Landlord refuses to consent to this Sublease, this Sublease shall terminate and neither party shall have any continuing obligation to the other with respect to the Premises; provided Sublessor shall return the Deposit, if previously delivered to Sublessor, to Sublessee. d. Authority. Each person executing this Sublease on behalf of a party hereto represents and warrants that he or she is authorized and empowered to do so and to thereby bind the party on whose behalf he or she is signing. e. Attorneys' Fees. In the event either party shall bring any action or proceeding for damages or for an alleged breach of any provision of this Sublease to recover rents, or to enforce, protect or establish any right or remedy hereunder, the prevailing party shall be entitled to recover reasonable attorneys' fees and court costs as part of such action or proceeding. 9 f. Holdover. This Sublease shall terminate without further notice at the expiration of the Sublease Term. If Sublessee holds over at the Premises or any part thereof after the expiration or earlier termination of the Term, such holding over shall constitute a month-to-month tenancy, at a rent equal to one hundred fifty percent (150%) of the base rent due under this Sublease. Nothing in the foregoing sentence shall be deemed sublessor's permission for Sublessee to hold over, and acceptance of Base Rent by Sublessor following expiration of termination of the Sublease shall not constitute a renewal of this Sublease. In addition to the foregoing, Sublessee shall indemnify, defend by counsel satisfactory to Sublessor, protect and hold Sublessor harmless from any and all liabilities, claims, causes of action, damages, costs or expenses (including reasonable attorney's fees) directly or indirectly resulting from Sublessee's holding over at the Premises beyond the expiration or termination of the Term. g. Access. Sublessor reserves the right to enter the Premises upon reasonable notice to Sublessee (except that in case of emergency no notice shall be necessary) in order to inspect the Premises and/or the performance by Sublessee of the terms of this Sublease. h. Time. Time is of the essence of every provision of this Sublease. 10 IN WITNESS WHEREOF, the parties hereto have executed one (1) or more copies of this Sublease, dated as of the Effective Date.

Landlord shall notify Tenant in writing of Substantial Completion and Tenant shall commence occupancy of the Initial Premises on the Commencement Date. Tenant shall occupy the Additional Space on the Second Commencement Date. Tenant shall occupy the Additional Space on the Second Commencement Date. In the event that the Tenant contends that the Tenant Improvements have not in fact been Substantially Completed, Tenant shall notify Landlord in writing of its objections within ten (10) calendar days after its receipt of the Landlord's notice described in the preceding sentence. Landlord shall have a reasonable time after its receipt of Tenant's notice in which to take such action as may be necessary to achieve Substantial Completion, and shall notify Tenant in writing when such action has been completed. Notwithstanding any notification by Tenant to the contrary, taking of possession by Tenant shall establish the Commencement Date as specified in the definition of that term and that the Premises and Tenant Improvements are in good and satisfactory condition, as and when possession was so taken and that the Commencement Date occurred. Tenant acknowledges that no representations as to the condition of the Premises have been made by Landlord, unless such are expressly set forth in this Lease. In the event of any dispute as to whether the Tenant Improvements have been Substantially Completed in accordance with the Plans and Specifications, the certificate of Landlord's architect or general 6 contractor shall be conclusive. If on the Commencement Date, Punch List Work for the Tenant Improvements remains to be completed, Landlord and Tenant shall agree on such Punch List Work prior to occupancy by Tenant and Landlord will promptly complete it after the Commencement Date. In no event shall Punch List Work delay or postpone the occurrence of the Commencement Date. Changes to the Plans and Specifications shall require the written consent of Landlord and Tenant.

All terms of this Lease, including Tenant's indemnifications and obligation to maintain insurance, but excluding payment of rent, shall apply to such early entry by Tenant. 2.5 Tenant's Contribution to Tenant Improvement Costs. If the cost of the Tenant Improvements exceeds the Tenant Improvement Allowance, Tenant shall pay to Landlord such excess within thirty (30) Business Days after demand by Landlord. If Tenant fails to pay to Landlord the cost of any such excess Tenant Improvements as and when due, Landlord may elect to halt work on the Tenant Improvements pending such timely payment, and the Commencement Date shall be deemed to have occurred on the date that the Tenant Improvements would have been Substantially Completed absent such interruptions and the delay by them. Upon the expiration or sooner termination of this Lease, all Tenant Improvements and all additions or alterations to the Premises made by Tenant or performed by Landlord on Tenant's behalf, shall become the property of Landlord, subject only to Tenant's right to remove property under the paragraph captioned "Tenant Alterations". [At Landlord's election and upon notice to Tenant, Tenant shall be required to remove all Tenant Improvements or Tenant Alterations upon the expiration or earlier termination of this Lease]. 2.6 Memorandum of Commencement Date.

Landlord makes no representation or warranty as to the suitability of the Premises for Tenant's intended use. Tenant shall, at its own cost and expense, obtain and maintain any and all licensees, permits, and approvals necessary or appropriate for its use, occupation and operation of the Premises. Tenant's inability to obtain or maintain any such license, permit or approval necessary or appropriate for its use, occupation or operation of the Premises shall not relieve it of its obligations under this Lease, including the obligation to pay Base Rent and Additional Rent. No act shall be done in or about the Premises that is unlawful or that will increase the existing rate of insurance on any or all of the Land or Building. Tenant shall not commit or allow to be committed any waste upon the Premises, or any public or private nuisance or other act or thing which disturbs the quiet enjoyment of any other tenant in the Project or which would violate any of Landlord's contracts affecting any or all of the Project, or which would create or contribute to any work stoppage, strike, picketing, labor disruption or dispute, or which would interfere in any way with the business of Landlord or any other tenant in the Project or with the rights or privileges of any contractors, subcontractors, licensees, agents, concessionaires, subtenants, servants, employees, customers, guests, invitees or visitors or any other persons lawfully in and upon the Project, or which would cause any impairment or reduction of the good will or reputation of the Project. Tenant shall not, without the prior written consent of Landlord, use any apparatus, machinery or device in or about the Premises which will cause any substantial noise or vibration or any increase in the normal use of electric power. Landlord warrants that the electrical power is sufficient to the building to accommodate Tenant's use per the mutually agreeable space plan. The cost of any improvements to the electrical systems to the Building to accommodate power usage in excess of that set forth in the plan shall be deducted from the Tenant Improvement Allowance. If any of Tenant's machines and equipment should disturb the quiet enjoyment of any other tenant in the Building, then Tenant shall provide, at its sole cost and expense, adequate 7 insulation or take other such action, including removing such machines and equipment, as may be necessary to eliminate the disturbance. Tenant shall comply with all Governmental Requirements relating to its use, occupancy and operation of the Premises and shall observe such reasonable rules and regulations as may be adopted and published by Landlord from time to time for the safety, care and cleanliness of the Premises and the Building, and for the preservation of good order in the Building, including the Rules and Regulations attached to this Lease as Exhibit D.

Tenant agrees to pay Base Rent to Landlord without demand, deduction, credit, adjustment or offset of any kind or nature, payable in lawful money of the United States in advance, on or before the first day of each calendar month of the Lease Term. Base Rent for any partial month at the beginning or end of the Lease Term shall be prorated. Upon execution of this Lease, Tenant shall pay to Landlord the amount specified in the definition of Prepaid Rent for the month specified in the definition of that term. Base Rent for any partial month at the beginning of the Lease Term shall be paid by Tenant on the Commencement Date.

(Intentionally Omitted). 3.3 Additional Rent. Definitions of certain terms used in this paragraph are set forth in subparagraph 3.3.6. Tenant agrees to pay to Landlord additional rent as computed in this paragraph (individually and collectively the "Additional Rent"): 3.3.1 Rental Adjustment for Estimated Operating Costs. Landlord shall furnish Tenant a written statement of Estimated Operating Costs Allocable to the Premises for each Year and the amount payable monthly by Tenant for such costs shall be computed as follows: one-twelfth (1/12) of the amount, if any, by which the Estimated Operating Costs Allocable to the Premises exceeds the Base Amount shall be Additional Rent and shall be paid monthly by Tenant for each month during such Year after the Commencement Date. If the Commencement Date occurs on a date other than the first day of the Year, the statement provided by Landlord to Tenant and the computation of the monthly payment amount shall be determined based on a proration of the excess amount over a 360-day year. If such written statement (except the first statement, which shall be prorated pursuant to the previous sentence) is furnished after the commencement of the Year, Tenant shall also make a retroactive lump-sum payment equal to the amount of the monthly payment amount multiplied by the number of months during the Year after the Commencement Date for which no payment was paid. 3.3.2 Actual Costs. After the close of each Year during the Lease Term, Landlord shall deliver to Tenant a written statement setting forth the Operating Costs Allocable to the Premises during the preceding Year. If such costs for any Year exceed the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.3.1 for such Year, Tenant shall pay the amount of such excess to Landlord within twenty (20) Business Days after receipt of such statement by Tenant. If such statement shows the Operating Costs Allocable to the Premises to be less than the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.3.1, then the amount of such overpayment shall be paid by Landlord to Tenant within twenty (20) Business Days following the date of such statement. 8 3.3.3 Determination. The determination of Operating Costs Allocable to the Premises shall be made by Landlord. Any sums payable under this Lease pursuant to this paragraph shall be Additional Rent and, in the event of nonpayment of such sums, Landlord shall have the same rights and remedies with respect to such nonpayment as it has with respect to nonpayment of the Base Rent due under this Lease. In the event that Landlord in its reasonable discretion determines that it would be more equitable to allocate any Operating Cost to only the Building, Landlord reserves the right to do so with appropriate adjustments to Tenant's Pro Rata Share of such Cost so that the allocation is to those tenants who occupy the Building. 3.3.4 End of Term.

Without Limiting the preceding sentence, Tenant shall also provide Landlord with: (a) such financial information as Landlord may reasonably request concerning the proposed subtenant or assignee, including recent financial statements certified as accurate and complete by a certified public accountant and by the president, managing partner or other appropriate officer of the proposed subtenant or assignee; (b) proof satisfactory to Landlord that the proposed subtenant or assignee will immediately occupy and thereafter use the entire Premises (or any sublet portion of the Premises) for the remainder of the Lease Term (or for the entire term of the sublease, if shorter) in compliance with the terms of this Lease except for the amount of rent due, which may be more or less than the amount set forth herein provided that Tenant reaffirms its primary liability under this Lease; and (c) a copy of the proposed sublease or assignment or letter of intent. At the same time that Tenant provides Landlord with notice of its desire to assign or sublease, Tenant shall pay to Landlord the sum of $400 as Landlord's fee for processing such proposed assignment and sublease, including attorneys' fees incurred by Landlord with respect to such processing. Receipt of such fee shall not obligate Landlord to approve the proposed assignment or sublease. 4.16.3 In determining whether to grant or withhold consent to a proposed assignment or sublease, Landlord may consider, in good faith, any commercial factor it deems relevant. Without limiting what may be construed as a factor considered by Landlord in good faith, Tenant agrees that any one or more of the following will be proper grounds for Landlord's disapproval of a proposed assignment or sublease: 19 (a) The proposed assignee or subtenant is or will be unwilling or unable to execute and deliver to Landlord an ERISA Certificate in the form consistent with the provisions of the paragraph entitled "ERISA Representations" as may be updated by Landlord, or Landlord believes that the proposed assignment or sublease would constitute a prohibited transaction under or otherwise violate ERISA; (b) The proposed assignee or subtenant does not, in Landlord's good faith judgment, have sufficient financial worth to insure the full and timely performance under this Lease; (c) Landlord has received insufficient evidence of the financial worth or creditworthiness of the proposed assignee or subtenant to make the determination set forth in clause (b); (d) Landlord has received from any prior lessor of the proposed assignee or subtenant a negative report concerning such prior lessor's experience with the proposed assignee or subtenant; (e) Landlord has had prior negative leasing experience with the proposed assignee or subtenant; (f) The use of the Premises by the proposed assignee or subtenant will not be [identical] in compliance with the Permitted Uses; (g) In Landlord's reasonable judgment, the proposed assignee or subtenant is engaged in a business, or the Premises or any part of the Premises will be used in a manner, that is not in keeping with the then standards of the Building or Project, or that is not compatible with the businesses of other tenants in the Building or Project, or that is inappropriate for the Building or Project, or that will violate any negative covenant as to use contained in any other lease of space in the Project; The use of the Premises by the proposed assignee or subtenant will violate any Governmental Requirement or such proposed use may create a violation of Access Laws; (i) Tenant is in default of any obligation of Tenant under this Lease, or Tenant has defaulted under this Lease on three (3) or more occasions during the twenty-four (24) months preceding the date that Tenant shall request such consent; (j) Landlord does not approve, in its reasonable discretion, of any of the tenant improvements required for the proposed assignee or subtenant; or (k) Landlord has had contact with the proposed assignee or subtenant, in the six (6) months preceding Tenant's request. regarding the leasing of space by such proposed assignee or subtenant in the Project, unless Landlord no longer has space sufficient for such assignee's or subtenant's needs. 4.16.4 Within fifteen (15) Business Days after Landlord's receipt of all required information to be supplied by Tenant pursuant to this paragraph, Landlord shall notify Tenant of Landlord's approval, disapproval or conditional approval of any proposed assignment or subletting.

Landlord shall have the right to transfer and assign, in whole or in part, its rights and obligations under this Lease and in any and all of the Project. If Landlord sells or transfers any or all of the Building, including the Premises, Landlord and Landlord's Agents shall, upon consummation of such sale or transfer, be released automatically from any liability relating to obligations or covenants under this Lease to be performed or observed after the date of such transfer, and in such event, Tenant agrees to look solely to Landlord's successor-in-interest with respect to such liability; provided that, as to the Security Deposit and Prepaid Rent, Landlord shall not be released from liability therefor unless Landlord has delivered (by direct transfer or credit against the purchase price) the Security Deposit or Prepaid Rent to its successor-in-interest. 4.18 Estoppel Certificates.

If Tenant fails to respond within ten (10) Business Days of its receipt of a written request by 21 Landlord as provided in this paragraph, Tenant shall be deemed to have admitted the accuracy of any information supplied by Landlord to a prospective purchaser, mortgagee or assignee. 4.19 Modification for Lender. If, in connection with obtaining construction, interim or permanent financing for the Building or Land, Landlord's lender, if any, shall request reasonable modifications to this Lease as a condition to such financing, Tenant will not unreasonably withhold or delay its consent to such modifications; provided that such modifications do not increase the obligations of Tenant under this Lease or materially adversely affect Tenant's rights under this Lease. 4.20 Hazardous Substances. 4.20.1 Tenant agrees that neither Tenant, any of Tenant's Agents will store, place, generate, manufacture, refine, handle, or locate on, in, under or around the Project any Hazardous Substance, except for storage, handling and use of reasonable quantities of cleaning fluids and office supplies in the Premises to be used in the ordinary course of Tenant's business in the Premises as reasonably necessary to accomplish the Permitted Use; provided that, (a) the storage, handling and use of such permitted Hazardous Substances must at all times conform to all Governmental Requirements and to applicable fire, safety and insurance requirements; (b) the types and quantities of permitted Hazardous Substances which are stored in the Premises must be reasonable and appropriate to the nature and size of Tenant's operation in the Premises and reasonable and appropriate for a first-class R&D/single story office building of the same or similar use and in the same market area as the Building; (c) no Hazardous Substance shall be spilled or disposed of on, in, under or around the Land or Building or otherwise discharged from the Premises or any area adjacent to the Land or Building; and (d) in no event will Tenant be permitted to store, handle or use on, in, under or around the Premises any Hazardous Substance which will increase the rate of fire or extended coverage insurance on the Land or Building, unless: (1) such Hazardous Substance and the expected rate increase have been specifically disclosed in writing to Landlord; (2) Tenant has agreed in writing to pay any rate increase related to each such Hazardous Substance; and (3) Landlord has approved in writing each such Hazardous Substance, which approval shall be subject to Landlord's discretion. 4.20.2 Tenant shall indemnify, defend and hold harmless Landlord and Landlord's Agents from and against any and all Claims arising out of any breach of any provision of this paragraph, which expenses shall also include laboratory testing fees, personal injury claims, clean-up costs and environmental consultants' fees. Tenant agrees that Landlord may be irreparably harmed by Tenant's breach of this paragraph and that a specific performance action may appropriately be brought by Landlord; provided that, Landlord's election to bring or not bring any such specific performance action shall in no way limit, waive, impair or hinder Landlord's other remedies against Tenant. 4.20.3 As of the execution date of this Lease, Tenant represents and warrants to Landlord that, except as otherwise disclosed by Tenant to Landlord, Tenant has no intent to bring any Hazardous Substances on, in or under the Premises except for the type and quantities authorized in the first paragraph of the section entitled "Hazardous Substances". 4.20.4 Landlord shall indemnify, defend and hold harmless Tenant from and against any Claims arising out of Hazardous Substances located on, in, under or around the Project if and to the extend they (a) first occurred and were pre-existing prior to the date of execution of this Lease, or (b) were caused or created by the negligence or willful misconduct of Landlord during the Lease Term. 4.20.5 Landlord represents and warrants to Tenant that as of the date of this Lease, to the best actual knowledge of Landlord's senior trust officer in charge of the Project, without duty of inquiry or investigation, there are no Hazardous Materials located in the Building or the Premises in violation of any applicable Governmental Requirements. 22 4.20.6 Landlord shall indemnify, defend and hold harmless Tenant from and against any and all Claims, excluding interruption of business and consequential damages, arising directly from the use, generation storage or disposal of Hazardous Materials by Landlord in the Building. 4.21 Access Laws. 4.21.1 Tenant agrees to notify Landlord immediately if Tenant receives notification or otherwise becomes aware of: (1) any condition or situation on, in, under or around the Premises which may constitute a violation of any Access Laws or (2) any threatened or actual lien, action or notice that the Project or any part of the Project is not in compliance with any Access Laws.

Notwithstanding the foregoing, the holder or beneficiary of such mortgage, deed of trust, ground lease, vendor's lien or similar instrument shall have the right to subordinate or cause to be subordinated any such mortgage, deed of trust, ground lease, vendor's lien or similar instrument to this Lease. Tenant further covenants and agrees that if the lender or ground lessor acquires the Premises as a purchaser at any foreclosure sale or otherwise, Tenant shall recognize and attorn to such party as landlord under this Lease, and shall make all payments required hereunder to such new landlord without deduction or set-off and, upon the request of such purchaser or other successor, execute, deliver and acknowledge documents confirming such attornment; provided that, Landlord provides Tenant with a commercially reasonable nondisturbance agreement on the standard form of the applicable lender or ground lessor.

Tenant shall pay or cause to be paid all sums legally due and payable by it on account of any labor performed or materials furnished in connection with any work performed on the Premises on which any lien is or can be validly and legally asserted against its leasehold interest in the Premises and Tenant shall indemnify, defend and hold harmless Landlord from any and all Claims arising out of any such asserted Claims. Tenant agrees to give Landlord immediate written notice of any such Claim. 4.29.2 Tenant shall be liable for all taxes levied or assessed against personal property, furniture or fixtures placed by Tenant in the Premises. If any such taxes for which Tenant is liable are levied or assessed against Landlord or Landlord's property and Landlord elects to pay them or if the assessed value of Landlord's property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, Tenant shall reimburse Landlord for the sums so paid by Landlord, upon demand by Landlord. SECTION 5: DEFAULT AND REMEDIES ------------------------------- 5.1 Events of Default. 5.1.1 The occurrence of any one or more of the following events shall constitute a material default and breach of this Lease by Tenant ("Event of Default"): (a) abandonment (without paying Base Rent or Additional Rent) of all or any portion of the Premises; (b) failure by Tenant to make any payment of Base Rent, Additional Rent or any other sum payable by Tenant under this Lease within five (5) Business Days after receipt from Landlord of written notice that such rent is past due, provided that, Tenant shall only be entitled to such notice twice in any 12-month period, and after such second notice, failure to pay shall be an Event of Default five (5) Business Days after its due date. 25 (c) failure by Tenant to observe or perform any covenant or condition of this Lease, other than the making of payments, where such failure shall continue for a period of ten (10) Business Days after written notice from Landlord; (d) (1) the making by Tenant of any general assignment or general arrangement for the benefit of creditors; (2) the filing by or against Tenant of a petition in bankruptcy, including reorganization or arrangement, unless, in the case of a petition filed against Tenant, the same is dismissed within twenty (20) Business Days; (3) the appointment of a trustee or receiver to take possession of substantially all of Tenant's assets located in the Premises or of Tenant's interest in this Lease; (4) any execution, levy, attachment or other process of law against any property of Tenant or Tenant's interest in this Lease; (5) adjudication that Tenant is bankrupt; (6) the making by Tenant of a transfer in fraud of creditors; or (7) the failure of Tenant to generally pay its debts as they become due; or (e) any information furnished by or on behalf of Tenant to Landlord in connection with the entry of this Lease is determined to have been materially false, misleading or incomplete when made. 5.1.2 Tenant shall notify Landlord promptly of any Event of Default or any facts, conditions or events which, with the giving of notice or passage of time or both, would constitute an Event of Default. 5.1.3 If a petition in bankruptcy is filed by or against Tenant, and if this Lease is treated as an "unexpired lease" under applicable bankruptcy law in such proceeding, then Tenant agrees that Tenant shall not attempt nor cause any trustee to attempt to extend the applicable time period within which this Lease must be assumed or rejected. 5.2 Remedies. If any Event of Default occurs, Landlord may at any time after such occurrence, with or without notice or demand except as stated in this paragraph, and without limiting Landlord in the exercise of any right or remedy at law which Landlord may have by reason of such Event of Default, exercise the rights and remedies, either singularly or in combination, as are specified or described in the subparagraphs of this paragraph: 5.2.1 Landlord may terminate this Lease and all rights of Tenant under this Lease either immediately or at a later date by giving Tenant written notice that this Lease is terminated. If Landlord so terminates this Lease, then Landlord may recover from Tenant the sum of: (a) the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been earned at the time of termination, and interest on such sums at the Default Rate; plus (b) the amount by which the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which would have been earned after termination until the time of award exceeds the amount of such rental loss, if any, as Tenant affirmatively proves could have been reasonably avoided and interest on such excess at the Default Rate; plus (c) the amount by which the aggregate of the unpaid Base Rent, Additional Rent and all other sums payable under this Lease for the balance of the Lease Term after the time of award exceeds the amount of rental loss, if any, as Tenant affirmatively proves could be reasonably avoided, with such difference being discounted to present value at the Prime Rate at the time of award; plus (d) any other amount necessary to compensate Landlord for the detriment proximately caused by Tenant's failure to perform Tenant's obligations under this Lease or which, in the ordinary course of things, would be likely to 26 result from such failure, including, leasing commissions, tenant improvement costs, renovation costs and advertising costs; plus (e) all such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law. 5.2.2 If Tenant abandons or surrenders (without paving Base Rent or Additional Rent) the Premises without Landlord's consent, or if Landlord re-enters the Premises as provided in subparagraph 5.2.3 or takes possession of the Premises pursuant to legal proceedings or through any notice procedure provided by law, then, if Landlord does not elect to terminate this Lease, Landlord may, from time to time, without terminating this Lease, either (a) recover all Base Rent, Additional Rent and all other sums payable under this Lease as they become due or (b) relet the Premises or any part of the Premises on behalf of Tenant for such term or terms, at such rent or rents and pursuant to such other provisions as Landlord, in its sole discretion, may deem advisable, all with the right, at Tenant's cost, to make alterations and repairs to the Premises and recover any deficiency from Tenant as set forth in subparagraph 5.2.5. 5.2.3 Upon an Event of Default, Landlord shall also have the right, with or without terminating this Lease, to re-enter the Premises and remove all persons and property from the Premises. Landlord may cause property so removed from the Premises to be stored in a public warehouse or elsewhere at the expense and for the account of Tenant. 5.2.4 Upon an Event of Default, Landlord shall also have the right, without terminating this Lease, to accelerate and recover from Tenant the sum of all unpaid Base Rent, Additional Rent and all other sums payable under the then remaining term of the Lease, discounting such amount to present value at the Prime Rate. 5.2.5 None of the foregoing remedial actions, singly or in combination, shall be construed as an election by Landlord to terminate this Lease unless Landlord has in fact given Tenant written notice that this Lease is terminated: any act by Landlord to maintain or preserve the Premises; any efforts by Landlord to relet the Premises; any repairs or alterations made by Landlord to the Premises; any re-entry, repossession or reletting of the Premises by Landlord pursuant to this paragraph; or the appointment of a receiver, upon the initiative of Landlord, to protect Landlord's Interest under this Lease. If Landlord takes any of the foregoing remedial action without terminating this Lease, landlord may nevertheless at any time after taking any such remedial action terminate this Lease by written notice to Tenant. 5.2.6 If Landlord relets the Premises, Landlord shall apply the revenue from such reletting as follows: first to the payment of any indebtedness other than Base Rent, Additional Rent or any other sums payable under this Lease by Tenant to Landlord; second to the payment of any cost of reletting (including finders' fees and leasing commissions); third to the payment of the cost of any alterations, improvements, maintenance and repairs to the Premises; and fourth to the payment of Base Rent, Additional Rent and other sums due and payable and unpaid under this Lease. Landlord shall hold and apply the residue, if any, to payment of future Base Rent, Additional Rent and other sums payable under this Lease as the same become due, and shall deliver the eventual balance, if any, to Tenant. Should revenue from letting during any month, after application pursuant to the foregoing provisions, be less than the sum of the Base Rent, Additional Rent and other sums payable under this Lease and Landlord's expenditures for the Premises during such month, Tenant shall pay the deficiency to Landlord immediately upon demand. 27 5.2.7 Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the other remedies provided in this Lease or by law (all such remedies being cumulative), nor shall pursuit of any remedy provided in this Lease constitute a forfeiture or waiver of any Base Rent, Additional Rent or other sum payable under this Lease or of any damages accruing to Landlord by reason of the violation of any of the covenants or conditions contained in this Lease. 5.3 Right to Perform. If Tenant shall fail to pay any sum of money, other than Base Rent or Additional Rent, required to be paid by it under this Lease or shall fail to perform any other act on its part to be performed under this Lease, and Tenant shall fail to commence to cure such default within twenty (20) Business Days after notice of such failure by Landlord, or such shorter time if reasonable under the circumstances, or Tenant shall fail to continuously and diligently prosecute such cure to completion, then Landlord may, but shall not be obligated to, and without waiving or releasing Tenant from any obligations of Tenant, make such payment or perform such other act on Tenant's part to be made or performed as provided in this Lease. Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the nonpayment of sums due under this paragraph as in the case of default by Tenant in the payment of Base Rent. 5.4 Landlord's Default. In the event that Landlord defaults under or breaches this Lease, Tenant shall notify Landlord of such default or breach in writing, and Tenant shall not exercise any right or remedy which Tenant may have under this Lease or at law if Landlord commences to cure such default or breach within twenty (20) Business Days after receipt of Tenant's notice and thereafter diligently prosecutes the cure to completion. SECTION 6: MISCELLANEOUS PROVISIONS 6.1 Notices. Any notice, request or written communication required or permitted to be delivered under this Lease shall be: (a) in writing; (b) transmitted by personal delivery, express or courier service, United States Postal Service in the manner described below, or electronic means of transmitting written material; and (c) deemed to be delivered on the earlier of the date received or four (4) Business Days after having been deposited in the United States Postal Service, postage prepaid.

Those notices which contain a notice of breach or default or a demand for performance may be sent by any of the methods described in clause (b) above, but if transmitted by personal delivery or electronic means, shall also be sent concurrently by certified or registered mail, return receipt requested. 28 6.2 Attorney's Fees and Costs. In the event either party requires the services of an attorney in connection with enforcing the terms of this Lease, or in the event suit is brought for the recovery of Base Rent, Additional Rent or any other sums payable under this Lease or for the breach of any covenant or condition of this Lease, or for the restitution of the Premises to Landlord or the eviction of Tenant during the Lease Term or after the expiration or earlier termination of this Lease, the substantially prevailing party shall be entitled to a reasonable sum for attorney's and parallel's fees and court costs, including costs of appeal. 6.3 No Accord and Satisfaction. No payment by Tenant or receipt by Landlord of an amount less than the Base Rent or Additional Rent or any other sum due and payable under this Lease shall be deemed to be other than a payment on account of the Base Rent, Additional Rent or other such sum, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, nor preclude Landlord's right to recover the balance of any amount payable or Landlord's right to pursue any other remedy provided in this Lease or at law. 6.4 Successors: Joint and Several Liability. Except as provided in the paragraph captioned "Exculpation and Limitation of Liability" and subject to the paragraph captioned "Assignment and Subletting by Landlord", all of the covenants and conditions contained in this Lease shall apply to and be binding upon Landlord and Tenant and their respective heirs, executors, administrators, successors and assigns. In the event that more than one person, partnership, company, corporation or other entity is included in the term "Tenant," then each such person, partnership, company, corporation or other entity shall be jointly and severally liable for all obligations of Tenant under this Lease. 6.5 Choice of Law. This Lease shall be construed and governed by the laws of the state in which the Land is located. 6.6 No Waiver of Remedies. The waiver by Landlord of any covenant or condition contained in this Lease shall not be deemed to be a waiver of any subsequent breach of such covenant or condition nor shall any custom or practice which may develop between the parties in the administration of this Lease be construed to waive or lessen the rights of Landlord to insist on the strict performance by Tenant of all of the covenants and conditions of this Lease. No act or thing done by Landlord or Landlord's Agents during the Lease Term shall be deemed an acceptance or a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless made in writing and signed by Landlord. The mention in this Lease of any particular remedy shall not preclude Landlord from any other remedy it might have, either under this Lease or at law, nor shall the waiver of or redress for any violation of any covenant or condition in this Lease or in any of the rules or regulations attached to this Lease or later adopted by Landlord, prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by Landlord of Base Rent, Additional Rent or any other sum payable under this Lease with knowledge of a breach of any covenant or condition in this Lease shall not be deemed a waiver of such breach.
