Simultaneously with the execution and delivery of this Lease, Tenant shall deliver to Landlord a security deposit (the “Security Deposit”), which Security Deposit shall be in the Security Deposit Amount (as defined in Section 1.2) and shall consist either of cash or of a clean, irrevocable letter of credit satisfactory in form and content to Landlord and issued by an FDIC insured bank located in Boston reasonably satisfactory to Landlord in favor of the Landlord. During the Term hereof, and any extensions thereof, and for ninety (90) days after the expiration of the Term, or for so long thereafter as Tenant is in possession of the Premises or has unsatisfied obligations hereunder to Landlord, the Security Deposit shall be security for the full and timely performance of Tenant’s obligations under this Lease; which cash may be used or letter of credit drawn upon by Landlord and applied from time to time against outstanding obligations of Tenant hereunder without notice or demand. Tenant shall have no right to require Landlord to so apply the Security Deposit, nor shall Tenant be entitled to credit the same against rents or other sums payable hereunder; no interest shall accrue thereon. If the Security Deposit is in the form of a letter of credit, during the entire Term hereof, including any extension thereof, Tenant shall cause said letter of credit to be renewed, in identical form to that delivered herewith, no later than thirty (30) days prior to the date of expiration of same. Without limiting any other remedies of Landlord, in the event that Tenant fails to renew any letter of credit given hereunder at least thirty (30) days prior to the date of expiration thereof, then Landlord shall have the right to draw down the entire amount of said letter of credit and hold such sums as a cash deposit If and to the extent that Landlord makes such use of the Security Deposit, or any part thereof, the sum so applied by Landlord (from cash or from a drawing on the letter of credit) shall be restored to the Security Deposit, in cash, by Tenant upon notice from Landlord, and failure to pay Landlord the amount to be so restored (within the grace period applicable to Fixed Rent hereunder) shall be a default hereunder giving rise to all of Landlord’s rights and remedies applicable to a default in the payment of rent. In the event of a change of circumstance relating to the bank issuing the letter of credit, or Landlord otherwise reasonably believes the financial conditions of the issuing bank has been degraded, Landlord reserves the right to require Tenant to replace the letter of credit from time to time with a substitute similar letter of credit issued by another bank satisfactory to Landlord. No trust relationship is created herein between Landlord and Tenant with respect to said Security Deposit. Tenant acknowledges that the Security Deposit is not an advance payment of any kind or a measure of Landlord's damages in the event of Tenant's default; Landlord shall not be obliged to keep the Security Deposit as a separate fund or pay interest thereon but may commingle the Security Deposit with its own funds provided that Landlord shall be able to separately

Tenant shall post the Security Deposit with Landlord in the form of an unconditional, irrevocable, stand-by documentary letter of credit (“Letter of Credit”), as security for the full and faithful performance of each provision of this Lease to be performed by Tenant, and Tenant shall be required to maintain the Letter of Credit with Landlord, during the entire Term and any extended Term of this Lease. Notwithstanding anything to the contrary in this Lease, the Security Deposit shall be posted with the Landlord as follows: # cash in the sum of $200,000.00 upon the full execution and delivery of this Lease (the “Initial Security Deposit”), and # a Letter of Credit in the full amount of the Security Deposit within 10 business days following Tenant’s receipt of the Contingency Notice.

The beneficiary of the Letter of Credit shall be Landlord, and the Letter of Credit shall be transferable by Landlord to any person or entity succeeding to Landlord’s ownership of the Premises at Landlord’s cost. The Letter of Credit shall provide for an initial term of at least one year and shall provide that it renews automatically for additional one year terms successively unless the issuer delivers to Landlord at least 60 days’ advance notice of non-renewal by certified mail, return receipt requested, or overnight courier. Failure of Tenant to provide Landlord with a replacement letter of credit satisfactory to Landlord at least 30 days prior to the expiration of the letter of credit, in the event the issuer delivers to Landlord the notice of non- renewal set forth in the foregoing sentence, shall be deemed an Event of Default under the terms of this Lease which shall not require the giving of notice or the allowance of any grace period, and shall entitle Landlord to immediately draw funds under the Letter of Credit; provided, however, that Landlord shall not have the right to avail itself of any remedies with respect to such Event of Default unless funds under the Letter of Credit are not available to be drawn. In the event Landlord receives such funds under the Letter of Credit from the issuing bank in accordance with the terms of the foregoing sentence: # such Event of Default shall be deemed to be cured and Landlord shall hold and apply the funds so drawn, without interest, and only in accordance with the provisions of this Section as if cash in such amount had been posted by Tenant in lieu of the Letter of Credit; and # Tenant shall have the right to substitute a new Letter of Credit meeting the foregoing requirements, in which event Landlord will return the funds received from the issuing bank to Tenant within 30 days after receipt of such new Letter of Credit.
