CONDITION OF FIRST AMENDMENT ADDITIONAL PREMISES Tenant shall take the First Amendment Additional Premises "as-is", in the condition in which the First Amendment Additional Premises are in as of the Term Commencement Date in respect of the First Amendment Additional Premises, without any obligation on the part of Landlord to perform any work in order to prepare the First Amendment Additional Premises for Tenant's occupancy, and, except as set forth in Article 7(f) and Exhibit 7 of the Lease, without any representation by Landlord to Tenant as to the condition of the First Amendment Additional Premises.

Notwithstanding the foregoing, Landlord shall, at its sole cost and expense, install a separate electric submeter measuring the consumption of electric current in the First Amendment Additional Premises. 6. LANDLORD BASE BUILDING CODE COMPLIANCE WORK ISSUES A. The parties have identified certain items of work ("Base Building Code Compliance Work") listed on Exhibit 4, First Amendment, dated May 10, 1997, a copy of which is attached hereto and made a part hereof, which must be performed in order to bring the Base Building into compliance with applicable state and local law. Tenant shall perform such Base Building Code Compliance Work as part of the improvements which Tenant will be performing in the First Amendment Additional Premises. Landlord shall, at Tenant's election, either pay to Tenant or Tenant's contractor the cost of performing other items ("Landlord Cost Items") of Base Building Code Compliance Work, as identified on said Exhibit 4. Landlord shall pay for the Landlord Cost Items within thirty (30) days of its receipt of a requisition therefore after the completion of the applicable item of work. Such requisition shall include evidence reasonably satisfactory to Landlord of the amount of such Landlord Cost Item. B. The parties acknowledge that it is possible that, prior to Tenant's occupancy of the First Amendment Additional Premises, the Town of Bedford may order that work ("Additional Code Compliance Work"), other than the Base Building Code Compliance Work identified on Exhibit 4, First Amendment, be performed in order to bring the Base Building into compliance with law and in order to allow Tenant to legally occupy the First Amendment Additional Premises. If either Landlord and/or Tenant is so ordered to perform any Additional Code Compliance Work, then: -3- 4 (1) At Landlord's election, either: (i) Landlord shall pay to Tenant or Tenant's contractor the cost of performing the Additional Landlord Cost Items, as hereinafter defined, or (ii) Landlord shall engage its own contractor to perform the Additional Landlord Cost Items, and (2) The Rent Commencement Date in respect of the affected floor of the First Amendment Additional Premises shall be extended by the length of time (if any) that Tenant's occupancy of such floor of the First Amendment Additional Premises is delayed as the result of the performance of the Additional Landlord Cost Items. C. For the purposes of this Paragraph 6, "Additional Landlord Cost Items" shall be defined as any Additional Code Compliance Work other than such work as required as the result of Tenant's particular or unusual use or construction of any portion of the First Amendment Additional Premises. General business office use shall not be considered to be a particular or unusual use of the First Amendment Additional Premises, and construction necessary to allow for general business office use shall not be considered to be particular or unusual construction. Without limiting the foregoing, construction of a seating area in the sunken area on the first floor of the First Amendment Additional Premises shall not be considered to be particular or unusual use or construction. 7. TENANT'S EARLY TERMINATION RIGHT Tenant's early termination right, as set forth in Paragraph 1 of the Rider to the Lease shall have no applicability to the First Amendment Additional Premises (i.e. if Tenant exercises its early termination right under said Paragraph 1 with respect to the Existing Premises, the Lease shall remain in full force and effect with respect to the First Amendment Additional Premises). 8. TENANT'S EXTENSION OPTION Tenant's extension option with respect to the First Amendment Additional Premises may NOT be exercised independently of Tenant's extension option with respect to the Existing Premises (i.e. Tenant may NOT extend the term of the Lease with respect to the First Amendment Additional Premises without exercising its right to extend the term of the Lease with respect to the Existing Premises). However, Tenant's extension option with respect to the Existing Premises shall be independent of Tenant's extension option with respect to the First Amendment Additional Premises (i.e. Tenant shall have the right to extend the term of the Lease with respect to the Existing Premises without exercising its right to extend the term of the Lease with respect to the First Amendment Additional Premises). -4- 5 9. PARKING A. Tenant shall have the exclusive right, in connection with its demise of the First Amendment Additional Premises, to use the three (3) parking spaces located in the area shown as "Tenant's Building No. 3 Exclusive Parking Area" on Exhibit 3, First Amendment. Tenant's right to use Tenant's Building No. 3 Exclusive Parking Area shall be upon all of the same terms and conditions as are applicable to Tenant's right to use Tenant's Exclusive Parking Area, as set forth in Article 2.3 of the Lease. B. The present (i.e. as of the Execution Date) configuration of the common and exclusive parking areas in the Park is as set forth on Exhibit 3, First Amendment. C. Tenant's right to use Tenant's Exclusive Parking Area on an exclusive basis is appurtenant solely to Tenant's demise of the Existing Premises and Tenant's right to use Tenant's Building No. 3 Exclusive Parking Area on an exclusive basis is appurtenant solely to Tenant's demise of the First Amendment Additional Premises (i.e. from and after the termination of the term of the Lease in respect of the Tenant's Exclusive Parking Area, Tenant shall have no further right to use Tenant's Exclusive Parking Area on an exclusive basis and from and after the termination of the term of the Lease in respect of Tenant's Building No. 3 Exclusive Parking Area, Tenant shall have no further right to use Tenant's Exclusive Building No. 3 Parking Area). 10. LANDLORD'S TERMINATION RIGHTS BASED UPON VACANCY Landlord's termination right under Article 5.4 of the Lease shall apply to the Existing Premises independently of the First Amendment Additional Premises, provided however, that the Vacancy Period, as defined in Article 5.4, applicable to the First Amendment Additional Premises shall be three hundred sixty-five (365) consecutive days. In other words: A. If Tenant ceases to use all, or substantially all, of the Existing Premises for one hundred twenty (120) consecutive days, but Tenant continues to use the First Amendment Additional Premises, then Landlord shall have the right to terminate the term of the Lease in respect of the Existing Premises in accordance with Article 5.4, but Landlord shall not have the right to terminate the term of the Lease with respect to the First Amendment Additional Premises. B. If Tenant ceases to use all, or substantially all, of the First Amendment Additional Premises for the three hundred sixty-five (365) consecutive days, but Tenant continues to use the Existing Premises, then Landlord shall have the right to terminate the term of the Lease in respect of the First Amendment Additional Premises, but Landlord shall not have the right to terminate the term of the Lease with respect of the Existing Premises. -5- 6 11. TERMINATION RIGHTS BASED UPON CASUALTY AND TAKING In the event of a casualty or a taking which affects only one of the Buildings which would allow either party to exercise its rights, under either Article 18 or 20 of the Lease, to terminate the Lease, then, notwithstanding anything to the contrary herein contained, neither party shall have the right to terminate the term of the Lease with respect to the Building which is not affected by such casualty or taking. 12. TENANT'S SECURITY Tenant shall not be required to provide additional security (i.e. in addition to the $750,000.00 Letter of Credit which Tenant delivered to Landlord in connection the execution of the Lease) in connection with its demise of the First Amendment Additional Premises. The parties confirm and agree that said $750,000.00 Letter of Credit shall secure Tenant's obligations under the Lease, as hereby amended. 13. SIGNAGE Subject to obtaining Landlord's approval of the particulars therefor which shall not be unreasonably withheld, and Tenant's obtaining all necessary governmental approvals therefor, Tenant may at its sole cost and expense install an exterior monument sign in front the First Amendment Additional Premises. Such sign shall identify Tenant and shall be in a location approved by Landlord. If Tenant installs such monument sign, Tenant shall maintain the same in good order and repair at all times and shall remove the same from the Park at the expiration or earlier termination of the term of the Lease in respect of the First Amendment Additional Premises. 14. EXHIBIT 1 Exhibit 1, Sheets 1, 2, 3, and 4, dated March 11, 1996 shall have no applicability to the First Amendment Additional Premises and in lieu thereof, Exhibit 1, First Amendment Version, Sheets 1, 2, 4, and 4, dated May 10, 1997 shall apply to the First Amendment Additional Premises. -6- 7 15. As hereby amended, the Lease is ratified, confirmed, and approved in all respects. EXECUTED UNDER SEAL as of the date first above written. LANDLORD: BEACON PROPERTIES, L.P.
