Sublandlord shall not unreasonably withhold or delay such consent. The provisions of Article 11 of the Prime Lease are hereby incorporated herein in the manner set forth in Article 9 of this Sublease. Subtenant shall not have any right to hypothecate, mortgage or otherwise encumber this Sublease.

13. Insurance. From and after the Delivery Date, Subtenant shall maintain insurance in accordance with the provisions of Article 13 of the Prime Lease solely as it applies to the Subleased Premises, except that Prime Landlord and Sublandlord shall be named as additional insureds on such policies. Subtenant shall deliver to Sublandlord the certificate(s) evidencing such insurance on or before the Commencement Date and thereafter in accordance with the terms of the Prime Lease. Each of Subtenant and Sublandlord hereby waives and release all claims against the other party for damage or loss to its property which would be covered by a Special Form policy of insurance covering such property, whether or not such insurance is in place and collectible.

14. Default. (a) Sublandlord reserves the right to terminate this Sublease and Subtenant’s occupancy of the Subleased Premises on ten (10) business days written notice to Subtenant in the event that (i) Subtenant fails to make any monthly Base Rent or Additional Rent payment within five (5) business days after delivery of written notice to Subtenant of such failure, or (ii) Subtenant fails to observe and perform any of its obligations under this Sublease within fifteen (15) days after written notice thereof from Sublandlord, except to the extent such default cannot be cured within said fifteen (15) day period, in which event Subtenant shall have such additional time as may be necessary to cure such default so long as Subtenant has commenced cure within such fifteen (15) day period and is diligently pursuing the remedies necessary to cure such default. The acceptance of any late payments of Base Rent or Additional Rent shall not be deemed a waiver of Sublandlord’s rights under this section.

(b) Notwithstanding any other provision herein, Subtenant shall perform all of its obligations hereunder at such times, by such dates or within such periods as Sublandlord shall be required to perform its corresponding obligations under the Sublease. If Prime Landlord shall give any notice of failure or default under the Sublease or the Prime Lease, as applicable, arising out of any failure by Subtenant to perform any of its obligations hereunder (other than payment of money), then Sublandlord shall promptly furnish Subtenant with a copy thereof. If the Sublease or Prime Lease shall provide any grace or cure period for such failure or default then the grace or cure period hereunder shall expire two (2) business days prior to the date on which the grace or cure period under the Prime Lease shall expire. In no event shall this subsection (b) extend the time, date or period by or within which Subtenant is required to perform.

15. Security Deposit. (a) Concurrent with Subtenant’s execution and delivery of this Sublease to Sublandlord, Subtenant shall pay to Sublandlord by bank check or wire transfer of immediately available federal funds the sum of $197,370 (the “Security Deposit”) to be held by the Sublandlord as security for the Subtenant’s performance of all the Subtenant’s obligations under this Sublease. Sublandlord shall retain the Security Deposit in a non-interest-bearing account. Sublandlord shall in no event be obligated to apply the Security Deposit to Rental in arrears or damages for Subtenant’s default, although Sublandlord may so apply the Security Deposit, at its option. The Security Deposit, if not applied toward the payment of Rental in arrears or toward the payment of damages suffered by Sublandlord by reason of Subtenant’s default, shall be returned to Subtenant without interest when this Sublease is terminated or as otherwise provided in this Sublease once Subtenant has vacated the Subleased Premises and delivered possession thereof to Sublandlord in accordance with the terms and provisions hereof. If Sublandlord legally repossesses the Subleased Premises because of Subtenant’s default, Sublandlord may apply the Security Deposit to damages suffered to the date of such repossession and may apply the Security Deposit to such damages as may be suffered or shall accrue thereafter by reason of Subtenant’s default. If Sublandlord applies the Security Deposit in whole or in part, Subtenant shall, upon demand by Sublandlord, deposit sufficient funds to maintain the Security Deposit in an amount equal to $197,370. Failure of Subtenant to deposit such additional security shall entitle Sublandlord to avail itself of the remedies provided in this Sublease for nonpayment of Base Rent and Additional Rent by Subtenant. Provided that no Default by Subtenant then exists (after notice and a reasonable opportunity to cure), on the third anniversary of the Commencement Date, the Security Deposit shall be reduced to $131,580 for the remainder of the Term.

(b) At Subtenant’s election, in lieu of the cash Security Deposit required herein, Subtenant may deliver to Sublandlord a clean, unconditional irrevocable stand-by letter of credit drawn on a Massachusetts clearinghouse bank in a sum equal to the Security Deposit required hereunder, in the form attached hereto and made a part hereof as Exhibit C (the “Letter of Credit”). Sublandlord shall have the right to draw down the Letter of Credit in accordance with the provisions of this Section 15(b) and Section 15(d) hereof. The Letter of Credit and any proceeds thereof drawn down by Sublandlord (the “Security”) shall be held by Sublandlord as security for the payment of all Rental which shall or may become payable for the Term and for the faithful performance by Subtenant of all of the other covenants and agreements made on its part in this Sublease, but Sublandlord shall in no event be obligated to apply the Security to Rental in arrears or damages for Subtenant’s default, although Sublandlord may so apply the Security, at its option. Sublandlord shall have the absolute right to draw on the Letter of Credit in full immediately upon the occurrence of either of the following: (a) Subtenant shall fail to renew or replace the Letter of Credit in accordance with this Article; or (b) Subtenant shall be in default under this Sublease after the expiration of the applicable notice or cure period (a “Default”). If Sublandlord exercises its right to draw down the Letter of Credit and apply the proceeds thereof to satisfy any Subtenant obligation or Default, Subtenant shall, within five (5) business days of the date of Sublandlord’s draw down, replace the Letter of Credit with a new letter of credit complying with the provisions of this Section 15(b), so that the amount of the Security held by Sublandlord shall always be the sum herein set forth or such lesser sum provided by this Lease.

(c) Subtenant shall renew or replace the Letter of Credit at least thirty (30) days prior to its expiration date with a renewal or replacement Letter of Credit complying with the terms of this Article and having an expiration date no earlier than one year from its issuance, and will thereafter renew or replace such renewal or replacement Letter of Credit and each succeeding Letter of Credit thirty (30) days prior to its expiration, so that a Letter of Credit complying with the terms of this Sublease shall continuously remain in effect until the date occurring sixty (60) days after the expiration of the Term.

(d) In addition to its obligations to do so under Section 15(b) and Section 15(c), Subtenant shall replace the Letter of Credit within five (5) business days of receipt of written notice from Sublandlord that the issuer has (i) entered into a supervisory agreement or consent order with the Federal Deposit Insurance Corporation, the Office of Thrift Supervision, or any other state or federal regulatory authority with jurisdiction such issuer; or (ii) become subject to an order or directive of any of the foregoing authorities with respect to the regulation of its activities; or (iii) notified Sublandlord that it shall not (A) honor a draw under the Letter of Credit; or (B) renew or extend the Letter of Credit beyond its then current expiration date.

16. Subordination. This Sublease is subject and subordinate to the Prime Lease and all matters to which this Sublease and the Prime Lease are subordinate, and to any mortgage(s) which may now or hereafter affect such leases or the Building and/or the land on which the Building is located and all renewals, modifications, consolidations, replacements and extensions thereof. This subordination shall be self-operative; however, in confirmation thereof, Subtenant shall execute promptly any commercially reasonable instrument that Sublandlord, Prime Landlord or any mortgagee may request confirming such subordination; provided that no such instrument shall materially increase Subtenant’s obligation xxxxxx this Sublease or materially decrease any rights of Subtenant under this Sublease.

17. Termination and Amendment of Prime Lease. Sublandlord shall not voluntarily terminate the Prime Lease except pursuant to a right of termination arising out of casualty or condemnation expressly set forth in the Prime Lease, and Sublandlord shall not amend the Prime Lease in a manner adverse to Subtenant in any material respect. If the Prime Lease shall terminate for any reason, then this Sublease shall also terminate. Sublandlord shall not be liable for any such termination unless such termination (a) shall have arisen out of a default under the Sublease by Sublandlord not arising out of a default hereunder by Subtenant or (b) shall have been effected by Sublandlord in violation of this Section.

18. Directory Listings. Subject to the provisions of the Prime Lease, Subtenant may have its name on the building directory in the main entrance lobby to the Building and on the 21^st floor elevator directory, provided Subtenant has obtained the prior consent of Prime Landlord to the extent required under the Prime Lease.

The number of names that Subtenant shall have the right to install on the directory shall be equal to Subtenant’s Proportionate Share of the number of names Sublandlord is entitled to install on the directory.
