27.           Security Deposit

A.           To secure the full and faithful performance by Tenant of all the terms, provisions, conditions, covenants and obligations (including, without limitation, the payment of Base Rent and Additional Rent) on Tenant's part to be performed under this Lease, Tenant shall deliver to Landlord a security deposit in accordance with Section II.J. above and in the manner described in subsection B below in the form of  unconditional, clean, irrevocable "evergreen" letters of credit, payable on sight, in form and substance satisfactory to Landlord, issued by a bank which is a member of the Boston Clearing House Association. Landlord may present such letters of credit for payment (up to the amount of Tenant's liability under this Lease on account of such default) upon the occurrence of an event of default by Tenant, as provided in Section 22, beyond any applicable notice and cure period.  Such letters of credit shall have expiration dates that are no earlier than forty-five (45) days after the Termination Date.  Notwithstanding that the letters of credit on deposit with Landlord are to be "evergreen" letters of credit, if the letters of credit shall for any reason whatsoever expire or have expiration dates earlier than forty-five (45) days after the Termination Date, then subsequent or extension letters of credit in the amount of the then existing letters of credit, with expiration dates no earlier than forty-five (45) days after the Termination Date, and otherwise in form and substance acceptable to Landlord shall be delivered by Tenant to Landlord at least thirty (30) days prior to the expiration dates of the letters of credit they are replacing (time being of the essence).  The failure to timely deliver any subsequent or extension letters of credit shall constitute a material event of default under this Lease for which no notice need be given, and for which no grace or cure period need be allowed (notwithstanding anything set forth in this Lease to the contrary) and the letters of credit, then in effect, may be presented for payment and negotiated notwithstanding that no other default may then exist under this Lease and upon such presentment and negotiation, the default for Tenant's failure to so deliver shall be deemed to have been cured.  Landlord shall return the proceeds of the letters of credit, or so much of such proceeds as shall not have been applied in accordance with the terms of this Section, to Tenant on or before the date which is sixty (60) days following the expiration or earlier termination of the Term of this Lease and provided Tenant has surrendered possession of the Premises in accordance with this Lease.

B.           Commencing on March 1, 2009 and continuing on the first day of each month through June 1, 2009, Tenant shall deliver to Landlord an additional letter of credit, each in the amount of $50,000.

C.           If there is an event of default by Tenant beyond any applicable notice and cure period in respect of any of the terms, provisions, conditions, covenants and obligations of this Lease, including, but not limited to, the payment of Rent and Additional Rent, Landlord may, without first applying any other security, use, apply or retain the whole or any part of the proceeds of the letters of credit to the extent required for the payment of any Rent or Additional Rent or any other sum as to which Tenant is in default or for any sum which Landlord may incur or may be required to incur by reason of Tenant's default in respect of any of the terms, provisions, conditions, covenants and obligations on Tenant's part to be performed under this Lease, including but not limited to, any damages or deficiencies which accrued before or after the commencement of summary proceedings or other re-entry by Landlord.  Tenant agrees to replenish all or any portion of the security deposit used by Landlord upon demand.

D.           Every letter of credit deposited with Landlord shall be transferable by its terms without charge to Landlord and without any further responsibility and liability with respect to such security and Tenant agrees to look solely to such assignee of Landlord for the return of the letters of credit or the proceeds thereof.  The provisions of the preceding sentence are self-operative without the need for further documentation.  Tenant shall not assign or encumber or attempt to assign or encumber any letter of credit or any of the proceeds thereof.

10.           As of the date hereof, Section 38 of the Lease is deleted in its entirety.

11.           Notwithstanding any other term of the Lease, Successor Landlord reserves the right, from time to time, upon no less than thirty (30) days notice to Tenant, to relocate Tenant’s office space known as Mod 6-2 consisting of 9,892 RSF of the bottom floor of the Building to another location in the Building at Tenant’s sole cost.  Upon Tenant’s relocation, Tenant shall surrender the former Mod 6-2 location in accordance with Section 14 of the Lease and the parties shall substitute a new Exhibit A for the Exhibit A currently attached to the Lease.

Unless the square footage of the new Mod 6-2 space remains the same, Section II.D. shall be amended to reflect the new total square footage of the Premises and the new square footage of Mod 6-2, and Section II.I. shall be amended to reflect the new numerator for the Tenant’s Proportionate Share of the office space.

12.           On or before January 30, 2009, Tenant shall pay Successor Landlord the amount of $441,203.79, representing all outstanding amounts billed to Tenant and due Successor Landlord including, without limitation, Rent, Additional Rent and utility charges incurred as of January 22, 2009.

13.           Tenant shall reimburse Successor Landlord, from time to time, within ten (10) days of Tenant’s receipt of an invoice, as Additional Rent, for all reasonable legal fees and costs incurred by Successor Landlord in connection with this Second Amendment to Lease and the summary process proceeding commenced by Successor Landlord in the Westborough District Court.

14.           Capitalized terms not defined in this Second Amendment shall have the same meaning ascribed in the Lease.

15.           Except as amended by this Second Amendment to Lease, the Lease remains in full force and effect.

IN WITNESS WHEREOF, this Second Amendment is executed as of the date first written above.
