At the time of such payment Tenant may elect: i) to reduce the payment due to Landlord for the present value of future rent by 66% and pay that reduced amount in full satisfaction of Landlord's claim for future rent but without the right of any future reimbursement; or ii) pay the full present value of the future rent and be entitled to receive reimbursement from landlord of future rent actually received on a monthly basis (after deduction of the costs of re-renting) but not to exceed each month the amount paid by Tenant for future rent divided by the number of months in the term for which such amount was paid by Tenant. (b) In addition to, but without limitation or qualification of, any other right or remedy of the Landlord herein provided, if the Tenant shall default in the performance of any covenant, condition or stipulation contained in this Lease, Landlord may, after thirty (30) days written notice to Tenant, or without notice if, and in Landlord's reasonable opinion, an emergency exists, perform the same for the account and at the expense of Tenant, and the amount of any payments made or other expenses incurred by Landlord for such purposes shall be forthwith repaid by Tenant with interest thereon at the highest per annum rate allowed by law.

The provisions of this Paragraph shall survive the termination of this Lease. Nothing in this Paragraph shall in any manner increase Landlord's liability to Tenant or to any other person.

(c) Upon the termination of this Lease, or upon the termination of Tenant's right to possession without termination of the Lease: 1) Tenant shall surrender possession and vacate the Premises immediately, and Landlord may enter into and repossess said Premises, without or with process of law, and remove all persons and property therefrom in the same manner and with the same right as if this Lease had not been made, and for the purpose of such entry and repossession, Tenant waives any notice provided by law or otherwise to be given in connection therewith; and 2) Landlord may remove from the Premises any and all property found therein and such repossession shall not release Tenant from Landlord's obligation to pay the Rent herein provided. (d) In the event of termination of this Lease as provided in this paragraph, Landlord in addition to any and all rights and remedies allowed by law and equity, shall upon termination be entitled to recover damages in the amount equal to the present value of all the additional charges, "Rent Adjustments," penalties and Rent in this Lease for the entire residue of the Term or renewal term hereof after subtracting the reasonable rental value of the Premises, subject to the same election as provided in paragraph 19(a)5). (e) Any and all property which may be removed from the Premises by Landlord may be handled, removed, stored or otherwise disposed of by Landlord at the risk and expense of Tenant, and Landlord shall in no event be responsible for the preservation or the safekeeping thereof.

Landlord and Tenant agree that notwithstanding anything in the Lease Form, the Lease Form is modified and supplemented by this Addendum. Each term used herein with initial capital letters shall have the meaning ascribed to such term in the Lease Form unless specifically otherwise defined herein. In the event of any inconsistency between this First Addendum and the Lease Form, the terms of this First Addendum shall prevail. As used herein, the term "Lease" shall mean the Lease Form, this Addendum and all riders, exhibits, rules, regulations, covenants, conditions and restrictions referred to in the Lease Form or this Addendum. 1.PREMISES TERM. A. The Lease shall commence (the "Commencement Date") on the date by which Landlord has delivered possession of the Premises to Tenant. Landlord shall deliver possession of the Premises to Tenant upon execution of this Lease. If the Commencement Date has not occurred for any reasons whatsoever on or before the tenth (10th) day after the parties hereto have fully executed this Lease, then in addition to Tenant's other rights or remedies, Tenant may terminate this Lease by written notice to Landlord, whereupon any monies previously paid by Tenant to Landlord shall be reimbursed to Tenant. B. Landlord shall designate the Premises as 220 Business Park Drive and designate that adjacent space currently occupied by Trek Diagnostics in the Building as 210 Business Park Drive and shall promptly register these designations with the United States Post Office. 4. RENT. Rent for the first sixty (60) days of the Term shall be one-half the Rent under Section 4 of the Lease (i.e., $9,000 per month). No rent shall be due for the period from the Commencement Date through April 30, 2000. 6. TAXES. "Taxes" shall not include and Tenant shall not be required to pay any portion of any tax or assessment expense or any increase therein (a) in excess of the amount which would be payable if such tax or assessment expense were paid in 20 installments over the longest possible term; (b) imposed on land and improvements other than the land and improvements on which the leased Premises and Tenant's parking areas are located; (c) attributable to Landlord's net income, inheritance, gift, transfer, estate or state taxes; or (d) resulting from a change of ownership or transfer of any or all of the Building. 9. USE AND REPAIR OF PREMISES BY TENANT; UTILITIES. Landlord shall perform and construct, and Tenant shall have no responsibility to perform or construct, any repair, maintenance or improvement which could be treated as a "capital expenditure" under generally accepted accounting principles and which Landlord elects to construct or is required to construct by this Lease (i.e. two-hour fire wall). Notwithstanding anything contained in the Lease to the contrary, Tenant shall be solely responsible for constructing, repairing and maintaining all Tenant construction and leasehold improvements. 11. RIGHTS RESERVED BY LANDLORD. Landlord, except in the case of emergency, shall provide Tenant with twenty-four (24) hours' notice prior to entry of the Premises. Any such entry by Landlord shall comply with all reasonable security measures of Tenant and shall not impair Tenant's operations more than reasonably necessary. Landlord shall not exercise its rights under Section 11 of the Lease if such actions would unreasonably interfere with Tenant's use of the Premises or increase the obligations or decease the rights of Tenant under the Lease. In taking such actions, Landlord shall at all times use its best efforts to minimize any disruption to Tenant. 14(a). LOSS OR DAMAGE TO PROPERTY. Landlord shall not be released or indemnified from, and shall indemnify, defend, protect and hold harmless Tenant from, all losses, damages, liabilities, judgments, actions, claims, attorneys' fees, consultants' fees, payments, costs and expenses arising from the negligence or willful misconduct of Landlord or its agents, contractors, licensees or invitees. 14(c). LOSS OR DAMAGE TO PROPERTY. If there is any interruption, failure, stoppage or interference of the utilities or services to the Premises under the Lease or due to the presence of any Hazardous Materials on or about the Building (except to the extent released or emitted by Tenant), and such interruption continues for ten (10) consecutive calendar days, then Tenant shall be entitled to an equitable abatement of rent to the extent of the interference with Tenant's use of the Premises occasioned thereby. If the interference persists for more than forty-five (45) consecutive calendar days, then Tenant shall have the right to terminate the Lease. -2- 21 16. ASSIGNMENT AND SUBLETTING. Notwithstanding anything to the contrary in the Lease, Tenant may, without Landlord's prior written consent, sublet the Premises or assign the Lease to: (i) a subsidiary, affiliate, division or corporation controlling, controlled by or under common control with Tenant; (ii) a successor corporation related to Tenant by merger, consolidation, nonbankruptcy reorganization, or government action; or (iii) a purchaser of substantially all of Tenant's assets located in the Premises. For the purpose of this Lease, sale of Tenant's capital stock shall not be deemed an assignment, subletting, or any other transfer of the Lease or the Premises. 17. ALTERATIONS. In no event shall Tenant be required to remove the Initial Improvements from the Premises at the end of the Term. 18. UNTENANTABILITY. In the event Landlord determines that any destruction or damage can be reasonably repaired within one hundred twenty (120) days, but such destruction or damage are not in fact repaired within such period, Tenant may terminate the Lease by written notice to Landlord within thirty (30) days after the expiration of such period. 20. SUBORDINATION. Within thirty (30) days of the Commencement Date, Landlord shall cause all mortgagees, lenders, ground lessors and other parties currently holding security interest affecting the Premises or Building to execute a recognition and nondisturbance agreement which (i) provides that this Lease shall not be terminated so long as Tenant is not in default under this Lease and (ii) recognizes all of Tenant's rights under the Lease. Landlord agrees to diligently attempt to obtain the agreement of Mortgagees and Lenders. If the Mortgagees and/or Lenders refuse to execute such an agreement, failure to obtain such and agreement will not be a breach or default of this Lease by Landlord. 22. NOTICES. Any notice required under the Lease that is sent by mail shall be deemed received, if properly addressed, three (3) business days after any such notice is deposited in the United States mail certified, postage-prepaid, return-receipt requested. 24.

To the best knowledge of Landlord, (a) no Hazardous Material is present in, under or about the Building or the soil, surface water or groundwater thereof, (b) no underground storage tanks are present in, under or about the Building, and (c) no -3- 22 action, proceeding or claim is pending or threatened regarding the Building concerning any Hazardous Material or pursuant to any environmental law. Under no circumstance shall Tenant be liable for, and Landlord shall indemnify, defend, protect and hold harmless Tenant, its agents, contractors, stockholders, directors, successors, representatives, and assigns from and against, all losses, costs, claims, liabilities and damages (including attorneys' and consultants' fees) of every type and nature, directly or indirectly arising out of or in connection with any Hazardous Material present on the Commencement Date in, under or about the Building, or the soil, air, improvements, groundwater or surface water thereof, or the violation of any laws, orders or regulations, relating to any such Hazardous Material, and to the extent that any of the foregoing actually results from the release or emission of Hazardous Material by Landlord or its agents or employees after the Commencement Date in violation of applicable environmental laws. B. Tenant shall be entitled to use and store in or adjacent to the Premises Hazardous Material necessary for the operation of its business on the Premises. Any storage outside the building must be approved by the Landlord, City and Business Park Covenant Review Committee and all costs associated with City or Covenant Committee approval shall be paid by Tenant. Landlord hereby approves of Tenant's construction of a chemical storage vault in the Premises. 29. LANDLORD DEFAULT. In the event Landlord fails to perform any of its obligations under this Lease and (except in case of emergency posing an immediate threat to persons or property, in which case no prior notice shall be required) fails to cure such default within thirty (30) days after written notice from Tenant specifying the nature of such default where such default could reasonably be cured within said thirty (30) day period, or fails to commence such cure within said thirty (30) day period and thereafter continuously with due diligence prosecute such cure to completion where such default could not reasonably be cured within said thirty (30) day period, then Tenant may, in addition to its other remedies, cure any default of Landlord at Landlord's cost and deduct the cost of such cure from Rent, but in no event shall such deductions during any twelve (12) month period exceed the sum of three (3) months' Rent accruing during such period. The deductions from Rent described in the foregoing sentence shall be in addition to all other offsets, credits, abatements and reductions of or against rent to which Tenant may from time to time be entitled under this Lease. If Tenant at any time by reason of Landlord's default reasonably pays any sum or does any act that requires the payment of any sum, the sum paid by Tenant shall be immediately due from Landlord to Tenant at the time the sum is paid. Any and all rights and remedies herein created for Tenant shall be cumulative and -4- 23 use of one remedy shall not be taken to exclude or waive the right to the use of another and Tenant shall have the remedies available to Tenant under applicable law. 30. REASONABLE EXPENDITURES. Any expenditure by a party permitted or required under the Lease, for which such party is entitled to demand and does demand reimbursement from the other party, shall be limited to the fair market value of the goods and services involved, shall be reasonably incurred, and shall be substantiated by documentary evidence available for inspection and review by the other party or its representative during normal business hours. 31. CONDITION OF PREMISES. Landlord warrants and represents that as of the Commencement Date the Premises will be in good condition and repair, the roof shall be in good condition and watertight, and the electrical, mechanical, HVAC, plumbing, elevator and other systems serving the Premises will be in good condition and repair. The parties acknowledge that the electrical service to the Premises may not be adequate for 800 amp service. Tenant intends to install a 1600 amp service. Installation of the 1600 amp service will be at Tenant's sole expense. Landlord shall be responsible for and pay the cost of the abandonment and removal (if required by the utility or building inspector) of the existing electric service to the Premises. 32. NO LIEN. Trade fixtures, furniture, equipment and other personal property installed in the Premises ("Tenant's Property") shall at all times be and remain Tenant's property. Tenant may at any time remove Tenant's Property from the Premises, provided that Tenant repairs all damage caused by such removal. Landlord shall have no security interest or lien on any item of Tenant's Property. Landlord waives any right of distraint, distress for rent or Landlord's lien that may arise at law. 33. COMPLIANCE WITH LAWS. Tenant shall not be required to comply with or cause the Premises to comply with any laws, rules or regulations requiring alterations or improvements unless the compliance with any of the foregoing is necessitated solely due to Tenant's particular use of the Premises or Tenant's construction on the Premises. 34. IMPROVEMENTS. A. Landlord shall perform, at its sole cost and expense, in a good and workmanlike manner and in compliance with all laws, the following alterations and improvements to the Building (the "Landlord Work"): (1) install a two-hour rated fire wall to demise the space; (2) "cap" of all plumbing in the space; (3) secure safely all electrical -5- 24 disconnects; (4) ensure that the heating and air conditioning systems is in good working condition as of the Commencement Date (but shall not be required to install larger or additional units to increase capacity); (5) replace and decontaminate all filters and existing duct work (or provide documentation that such replacement and decontamination has already been completed); and (6) clear power panel from lockouts. Landlord shall complete item (1) of this Section 34 on or before the thirtieth (30th) day after full execution of this Lease.

B. Landlord acknowledges that Tenant will be constructing certain improvements in the Premises necessary for the operation of its business in the Premises (the "Initial Improvements"). Landlord hereby approves of the Initial Improvements described on the preliminary plans and specifications attached to the Lease as Exhibit B. C. In the event Tenant is unsuccessful in obtaining all required consents, approvals and permits under the Lease and under applicable law in connection with the Initial Improvements or in connection with the operation of Tenant's business in the Premises, or in the event Tenant determines in its sole discretion that it cannot obtain all such consents, approvals and permits in a commercially reasonable manner, then Tenant may terminate this Lease upon thirty (30) days written notice, provided such written notice to terminate the Lease is delivered to Landlord on or before August 1, 2000. 35. RIGHT OF FIRST OFFER. If Landlord from time to time determines to lease any space in the building outside of the Premises (each space an "Expansion Space"), then Landlord shall first notify Tenant of the terms on which Landlord is willing to lease such Expansion Space. If Tenant, within five (5) business days after receipt of Landlord's written notice indicates in writing its agreement to lease the Expansion Space on the terms stated in Landlord's notice, then Landlord shall lease to Tenant and Tenant shall lease from Landlord the Expansion Space on the terms stated in Landlord's notice.

If Landlord does not lease the Expansion Space within ninety (90) days after the expiration of said five (5) business day period, any further transaction shall be deemed a new determination by Landlord to lease such Expansion -6- 25 Space and the provisions of this paragraph shall again be applicable with respect to such Expansion Space. 36.
