a. In order that the Rent payable during the Term reflect any increases in Project Operating Costs, Tenant agrees to pay to Landlord as Rent, Tenant’s Proportionate Share of all increases in costs, expenses and obligations attributable to the Project and its operation, all as provided below.

b. If, during any calendar year during the Term, Project Operating Costs exceed the Project Operating Costs for the Base Year, Tenant shall pay to Landlord, in addition to the Base Rent and all other payments due under this Lease, an amount equal to Tenant’s Proportionate Share of such excess Project Operating Costs in accordance with the provisions of this Section 5.3b.

(1) The term “Project Operating Costs” shall include all those items described in the following subparagraphs (a) and (b).

(a) All taxes, assessments, water and sewer charges and other similar governmental charges levied on or attributable to the Building or Project or their operation, including without limitation, (i) real property taxes or assessments levied or assessed against the Building or Project, (ii) assessments or charges levied or assessed against the Building or Project by an redevelopment agency, (iii) any tax measured by gross rentals received from the leasing of the premises, Building or Project, excluding any net income, franchise, capital stock, estate or inheritance taxes imposed by the State or federal government or their agencies, branches or departments; provided that if at any time during the Term any governmental entity levies, assesses or imposes on Landlord any (1) general or special, ad valorem or specific, excise, capital levy or other tax, assessment, levy or charge directly on the Rent received under this Lease or on the rent received under any other leases of space in the Building or Project, or (2) any license fee, excise or franchise tax, assessment, levy or charge measured by or based, in whole or in part, upon such rent, or (3) any transfer, transaction, or similar tax, assessment, levy or charge based directly or indirectly upon the transaction represented by this Lease or such other leases, or (4) any occupancy, use, per capita or other tax, assessment, levy or charge based directly or indirectly upon the use or occupancy of the Premises or other premises within the Building or Project, then any such taxes, assessments, levies and charges shall be deemed to be included in the term Project Operating Costs. If at any time during the Term the assessed valuation of, or taxes on, the Project are not based on a completed Project having at least ninety-five percent (95%) of the Rentable Area occupied, then the “taxes” component of Project Operating Costs shall be adjusted by Landlord to reasonably approximate the taxes which would have been payable if the Project were completed and at least ninety-five percent (95%) occupied.

(b) Operating costs incurred by Landlord in maintaining and operating the Building and Project, including without limitation the following: costs of (1) utilities; (2) supplies; (3) insurance (including public liability, property damage, earthquake, and fire and extended coverage insurance for the full replacement cost of the Building and Project as required by Landlord or its lenders for the Project); (4) services of independent contractors; (5) compensation (including employment taxes and fringe benefits) of all persons who perform duties connected with the operation, maintenance, repair or overhaul of the Building or Project, and equipment, improvements and facilities located within the Project, and gardeners (but excluding persons performing services not uniformly available to or performed for substantially all Building or Project tenants); (6) operation and maintenance of a room for delivery and distribution of mail to tenants of the Building or Project as required by the U.S. Postal Service (including, without limitation, an amount equal to the fair market rental

value of the Mail room premises); (7) management of the Building or Project, whether managed by Landlord or an independent contractor (including, without limitation, an amount equal to the fair market value of an yon-site manager’s office); (8) rental expenses for (or a reasonable depreciation allowance on) persona property used in the maintenance, operation or repair of the Building or Project; (9) costs, expenditures or charges (whether capitalized or not) required by any governmental or quasi-governmental authority; (10) amortization of capital expenses (including financing costs) (i) required by a governmental entity for energy conservation or life safety purposes, or (ii) made by Landlord to reduce Project Operating Costs; and (11) any other costs or expenses incurred by Landlord under this lease and not otherwise reimbursed by tenants of the Project. If at any time during the Term, less than ninety-five percent (95%) of the Rentable Area of the Project is occupied, the “operating costs” component of Project Operating Costs shall be adjusted by Landlord to reasonably approximate the operating costs which would have been incurred if the Project had been at least ninety-five percent (95%) occupied.

(2) Tenant’s Proportionate Share of Project Operating Costs shall be payable by Tenant to Landlord as follows:

(a) Beginning with the calendar year following the Base Year and for each calendar year thereafter (“Comparison Year”), Tenant shall pay Landlord an amount equal to Tenant’s Proportionate Share of the Project Operating costs incurred by Landlord in the Comparison Year which exceeds the total amount of Project Operating Costs payable by Landlord for the Base Year. This excess is referred to as the “Excess Expenses”.

(b) To provide for current payments of Excess Expenses, Tenant shall, at Landlord’s request, pay as additional rent during each Comparison Year, an amount equal to Tenant’s Proportionate Share of the Excess Expenses payable during Comparison Year, as estimated by Landlord from time to time. Such payments shall be made in monthly installments, commencing on the first day of the month following the month in which Landlord notifies Tenant of the amount it is to pay hereunder and continuing until the first day of the month following the month in which Landlord gives Tenant a new notice of estimated Excess Expenses. It is the intention hereunder to estimate from time to time the amount of the Excess Expenses for each comparison year and Tenant’s Proportionate Share thereof, and then to make an adjustment in the following year based on the actual Excess Expenses incurred for that Comparison Year.

(c) On or before April 1 of each Comparison Year after the first comparison Year (or as soon thereafter as is practical), Landlord shall deliver to Tenant a statement setting forth Tenant’s Proportionate Share of the Excess Expenses for the preceding Comparison Year. If Tenant’s Proportionate Share of the actual Excess Expenses for the previous Comparison Year exceeds the total of the estimated monthly payments made by Tenant for such year, Tenant shall pay Landlord the amount of the deficiency within ten (10) days of the receipt of the statement. If such total exceeds Tenant’s Proportionate Share of the actual Excess Expenses for such comparison Year, then Landlord shall credit against Tenant’s next ensuing monthly installment(s) of additional rent an amount equal to the difference until the credit is exhausted. If a credit is due from Landlord on the Expiration Date, Landlord shall pay Tenant the amount of the credit. The obligations of Tenant and Landlord to make payments required under this Section 5.3 shall survive the Expiration Date.

(d) Tenant’s Proportionate Share of Excess Expenses in any Comparison Year having less than 365 days shall be appropriately prorated.

(e) If any dispute arises as to the amount of any additional rent due hereunder, Tenant shall have the right after reasonable notice and at reasonable times to inspect Landlord’s accounting records at Landlord’s accounting office and, if after such inspection Tenant still disputes the amount of additional rent owed, a certification as to the proper amount shall be made by Landlord’s certified public accountant, which certification shall be final and conclusive. Tenant agrees to pay the cost of such certification unless it is determined that Landlord’s original statement overstated Project Operating Costs by more than five percent (5%).

(f) If this Lease sets forth an Expenses Stop at Section 2f, then during the Term Tenant shall be liable for Tenant’s Proportionate Share of any actual Project Operating Costs which exceed the amount of the Expense Stop. Tenant shall make current payments of such excess costs during the Term in the same manner as is provided for payment of Excess Expenses under the applicable provisions of SECTION 5.3b(2)(b) and (c) above.

5.4 Definition of Rent. All costs and expenses which Tenant assumes or agrees to pay to Landlord under this Lease shall be deemed additional rent (which, together with the Base Rent is sometimes referred to as the “Rent”). The Rent shall be paid to the Building manager (or other person) and at such place, as Landlord may from time to time designate in writing, without any prior demand therefor and without deduction or offset, in lawful money of the United States of America.

5.5 Rent Control. If the amount of Rent or any other payment due under this Lease violates the terms of any governmental restrictions on such Rent or payment, then the Rent or payment due during the period of such restrictions shall be the maximum amount allowable under those restrictions. Upon termination of the restrictions, Landlord shall, to the extent it is legally permitted, recover from Tenant the difference between the amounts received during the period of the restrictions and the amounts Landlord would have received had there been no restrictions.

5.6 Taxes Payable by Tenant. In addition to the Rent and any other Charges to be paid by Tenant hereunder, Tenant shall reimburse Landlord upon demand for any and all taxes payable by Landlord (other than net income taxes) which are not otherwise reimbursable under this Lease, whether or not now customary or within the contemplation of the parties, where such taxes are upon, measured by or reasonably attributable to (a) the cost or value of Tenant’s equipment, furniture, fixtures and other personal property located in the Premises, or the cost or value of any leasehold improvements made in or to the Premises by or for Tenant, other than Building Standard Work made by Landlord, regardless of whether title to such improvements is held by Tenant or Landlord; (b) the gross or net Rent payable under this Lease, including, without limitation, any rental or gross receipts tax levied by any taxing authority with respect to the receipt of the Rent hereunder; (c) the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion thereof; or (d) this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. If it becomes unlawful for Tenant to reimburse Landlord for any costs as required under this Lease, the

Base Rent shall be revised to net Landlord the same net Rent after imposition of any tax or other charge upon Landlord as would have been payable to Landlord but for the reimbursement being unlawful.

6. INTEREST AND LATE CHARGES.

If Tenant fails to pay when due any Rent or other amounts or charges which Tenant is obligated to pay under the terms of this Lease, the unpaid amounts hall bear interest at the maximum rate then allowed by law. Tenant acknowledges that the late payment of any Monthly Installment of Base Rent will cause Landlord to lose the use of that money and incur costs and expenses not contemplated under this Lease, including without limitation, administrative and collection costs and processing and accounting expense, the exact amount of which is extremely difficult to ascertain. Therefore, in addition to interest, if any such installment is not received by Landlord within ten (10) days from the date it is due, Tenant shall pay Landlord a late charge equal to five percent (5%) of such installment. Landlord and Tenant agree that this late charge represents a reasonable estimate of such costs and expenses and is fair compensation to Landlord for the loss suffered from such nonpayment by Tenant. Acceptance of any interest or late charge shall not constitute a waiver of Tenant’s default with respect to such nonpayment by Tenant nor prevent Landlord from exercising any other right or remedies available to Landlord under this Lease.

7. SECURITY DEPOSIT.

Tenant agrees to deposit with Landlord the Security Deposit set forth at Section 2.0 upon execution of this Lease, as security for Tenant’s faithful performance of its obligations under this Lease. Landlord and Tenant agree that the Security Deposit may be commingled with funds of Landlord and Landlord shall have no obligation or liability for payment of interest on such deposit.

Tenant shall not mortgage, assign, transfer or encumber the Security Deposit without the prior written consent of Landlord and any attempt by Tenant to do so shall be void, without force or effect and shall not be binding upon Landlord.

If Tenant fails to pay any Rent or other amount when due and payable under this Lease, or fails to perform any of the terms hereof, Landlord may appropriate and apply or use all or any portion of the Security Deposit for Rent payments or any other amount then due and unpaid, for payment of any amount for which Landlord has become obligated as a result of Tenant’s default or breach, and for any loss or damage sustained by Landlord as a result of Tenant’s default or breach, and Landlord may so apply or use this deposit without prejudice to any other remedy Landlord may have by reason of Tenant’s default or breach. If Landlord so uses any of the Security Deposit, Tenant shall, within ten (10) days after written demand therefor, restore the Security Deposit to the full amount originally deposited; Tenant’s failure to do so shall constitute an act of default hereunder and Landlord shall have the right to exercise any remedy provided for at Article 27 hereof. Within fifteen (15) days after the Term (or any extension thereof) has expired or Tenant has vacated the Premises, whichever shall last occur, and provided Tenant is not then in default on any of its obligations hereunder, Landlord shall return the Security Deposit to Tenant, or, if Tenant has assigned its interest under this Lease, to the last assignee of Tenant. If Landlord sells its interest in the Premises, Landlord may deliver this deposit to the purchaser of Landlord’s interest and thereupon be relieved of any further liability or obligation with respect to the Security Deposit.

8. TENANT’S USE OF THE PREMISES.

Tenant shall use the Premises solely for the purposes set forth in Tenant’s Use Clause. Tenant shall not use or occupy the Premises in violation of law or any covenant, condition or restriction affecting the Building or Project or the certificate of occupancy issued for the Building or Project, and shall, upon notice form Landlord, immediately discontinue any use of the Premises which is declared by any governmental authority having jurisdiction to be a violation of law or the certificate of occupancy. Tenant, at Tenant’s own cost and expense, shall comply with all laws, ordinances, regulations, rules and/or any directions of any governmental agencies or authorities having jurisdiction which shall, by reason of the nature of Tenant’s use or occupancy of the Premises, impose any duty upon TENANT or Landlord with respect to the Premises or its use or occupation. A judgment of any court of competent jurisdiction or the admission by Tenant in any action or proceeding against Tenant that Tenant has violated any such laws, ordinances, regulations, rules and/or directions in the use of the Premises shall be deemed to be a conclusive determination of that fact as between Landlord and Tenant. Tenant shall not do or permit to be done anything which will invalidate or increase the cost of any fire, extended coverage or other insurance policy covering the Building or Project and/or property located therein, and shall comply with all rules, orders, regulation, requirements and recommendations of the Insurance Services Office or any other organization performing a similar function. Tenant shall promptly upon demand reimburse Landlord for any additional premium charged for such policy by reason of Tenant’s failure to comply with the provisions of this Article. Tenant shall not do or permit anything to be done in or about the Premises which will in any way obstruct or interfere with the rights of other tenants or occupants of the Building or Project, or injure or annoy them, or use or allow the Premises to be used for any improper, immoral, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant shall not commit or suffer to be committed any waste in or upon the Premises.

Landlord shall also maintain and keep lighted the common stairs, common entries and restrooms in the Building.

Landlord shall not be liable under any circumstances for a loss of or injury to property or business, however occurring, through or in connection with or incidental to failure to furnish any such services. If Tenant uses heat generating machines or equipment in the Premises which affect the temperature otherwise maintained by the HVAC system, Landlord reserves the right to install supplementary air conditioning units in the Premises and

the cost thereof, including the cost or installation, operation and maintenance thereof, shall be paid by Tenant to Landlord upon demand by Landlord.

Tenant shall not consume water or electric current in excess of that usually furnished or supplied for the use of premises as general office space and light manufacturing and production assembly of medical devices, without first procuring the written consent of Landlord, which Landlord may refuse, and in the event of consent, Landlord may have installed a water meter or electrical outlets in the Premises to measure the amount of water or electric current consumed. The cost of any such meter and of its installation, maintenance and repair shall be paid for by the Tenant and Tenant agrees to pay to Landlord promptly upon demand for all such water and electric current consumed to as shown by said meters, at the rates charged for such services by the local public utility plus any additional expense incurred in keeping account of the water and electric current so consumed. If a separate meter is not installed, the excess cost for such water and electric current shall be established by an estimate made by a utility company or electrical engineer hired by Landlord at Tenant’s expense.

Nothing contained in this Article shall restrict Landlord’s right to require at any time separate metering of utilities furnished to the Premises. In the event utilities are separately metered, Tenant shall pay promptly upon demand for all utilities consumed at utility rates charged by the local public utility plus any additional expense incurred by Landlord in keeping account of the utilities so consumed. Tenant shall be responsible for the maintenance and repair of any such meters at its sole cost.
