Attention: Julie Guida

First month’s rent shall be due within five (5) days after Sublessee, Sublessor and Master Landlord have executed and delivered the Master Landlord’s Consent (as defined in Section 17) to this Sublease. Notwithstanding the foregoing, provided Sublessee is not in Default hereunder or under the Amended Master Lease, gross Rent (inclusive of Additional Rent) shall abate from the Commencement Date through November 30, 2008 (the “Abatement Period”). For the avoidance of doubt, provided Sublessee is not in Default hereunder or under the Amended Master Lease, Sublessee shall not be required to pay Base Rent or Additional Rent from the Commencement Date through November 30, 2008. If the Commencement Date does not occur on May 14, 2008 (unless due to Sublessee), the Abatement Period shall be extended one day for each day that the Commencement Date is delayed beyond May 14, 2008.

4. Security Deposit. Sublessee shall pay Sublessor the amount of One Hundred Fifty-three Thousand Four Hundred Seventy and 62/100 ($153,470.62) Dollars (equal to three months’ gross rent), within five (5) days after Sublessor, Sublessee and Master Landlord have executed and delivered the Master Landlord’s Consent (as defined in Section 17) to this Sublease, as security deposit for Sublessee’s faithful performance of Sublessor’s obligations hereunder. If Sublessee fails to pay rent or otherwise defaults with respect to any provision of this Sublease, Sublessor may, after the expiration of all applicable notice and cure periods, use, apply or retain all or any portion of the deposit for the payment of any rent or any other sum to which Sublessor may become obligated by reason of Sublessee’s default, or to compensate Sublessor for any loss or damage which Sublessor may suffer thereby. Sublessee shall not be

required to keep the deposit separate from its general account. If Sublessee performs all of Sublessor’s obligations hereunder, the deposit, or so much thereof as has not theretofore been applied by Sublessor or refunded to Sublessee, shall be returned, without payment of interest or other increments for its use, to Sublessee within 30 days after the expiration of the term hereof and after Sublessee has vacated the Premises. Notwithstanding the foregoing, provided that Sublessee is not then in Default and no event which with the passage of time or the giving of notice or both would constitute a Default exists, the Security Deposit shall be reduced to two months’ gross rent (the “Reduced Security Deposit Amount”) on and as of February 1, 2014 (the “Security Deposit Reduction Date”). Accordingly, if Sublessee is not in Default as of February 14, 2014 and no event which with the passage of time or the giving of notice or both would constitute a Default exists, Sublessor shall refund the excess Security Deposit within thirty (30) days after February 14, 2008. Notwithstanding the foregoing, if Sublessee is in Default on the Security Deposit Reduction Date or Sublessee is in breach of this Sublease but the applicable notice and cure period has not expired by such date, then upon Sublessee’s cure of any such Default or breach, Sublessee shall have the right to reduce the Security Deposit to the Reduced Security Deposit Amount, provided that if Sublessee has been in Default more than three (3) times during the Term prior to the Security Deposit Reduction Date then Sublessee shall have not have the right to reduce the Security Deposit after Security Deposit Reduction Date regardless if Sublessee ultimately cures such Default or breach.

Instead of a cash security deposit, Sublessee shall have the right at any time during the Sublease Term (including, without limitation, on or before the date that the cash Security Deposit is due hereunder) to replace the cash Security Deposit with a clean, unconditional and irrevocable Letter of Credit Security Deposit (the “Letter of Credit”). If Sublessee elects to deposit a Letter of Credit, the Letter of Credit and any substitute Letter of Credit shall be issued in a form and by a bank (the “Bank”) approved by Sublessor, in Sublessor’s reasonable discretion. Upon Sublessee’s deposit of the Letter of Credit with Sublessor, Sublessor shall immediately return the cash Security Deposit. Sublessee shall maintain the Letter of Credit, or a substitute Letter of Credit, from the Bank approved by Sublessor, in accordance with the terms hereof, in full force and effect at all times during the entire term of this Sublease (subject to terms of this Sublease) and for a period of thirty (30) days thereafter (the last day of such 30 day period shall be referred to as the “Return Date”) or until all obligations due from Sublessee under this Sublease have been paid in full. If the Letter of Credit expires before the Return Date, Sublessee shall replace the Letter of Credit deposited with Sublessor by providing Sublessor with a substitute Letter of Credit at least thirty (30) days prior to the expiration date of the then effective Letter of Credit being held by Sublessor in the amount required hereunder. Sublessor shall have the right to draw upon the Letter of Credit and apply such Letter of Credit or portion thereof to cure any Default of Sublessee under this Sublease in same manner described in this Section 4. Within thirty days following the expiration or earlier termination of this Sublease, Sublessor shall return the Letter of Credit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this paragraph or drawn upon by Sublessor and applied to cure any default of Sublessee existing at the expiration or earlier termination of this Sublease. If the Security Deposit is in the form of a Letter of Credit when the Security Deposit is reduced on February 14, 2014 as described above, Sublessee shall have the right to replace the existing Letter of Credit with a new Letter of Credit in the required amount. Upon such replacement Sublessor shall return the Letter of Credit previously in Sublessor’s possession.

5. Assignment/Subletting. Sublessee may not assign this Sublease in whole or in part or sublet the Premises, without the prior written consent of the Sublessor, which consent shall not be unreasonably withheld, conditioned or delayed, and Master Landlord to the extent Master Landlord’s consent is required. If permitted under the terms of the Amended Master Lease, Sublessor’s consent shall not be required for an assignment or sublease of all or any portion of the Premises to (i) any entity resulting from a merger of consolidation with Sublessee or any organization purchasing substantially all of Sublessee’s assets, (ii) any entity succeeding to substantially all the business and assets of Sublessee, (iii) any subsidiary, affiliate or parent of Sublessee, (iv) any entity controlling, controlled by or under common control with Sublessee, or (v) any entity resulting from the reorganization of Sublessee outside of bankruptcy organization.

20. Casualty; Eminent Domain. In the event of a fire or other casualty affecting the Building or the Premises, or of a taking of all or a part of the Building or the Premises under the power of eminent domain, except as set forth in the Amended Master Lease: (i) Sublessor shall not have any obligation to repair or restore the Premises or any alterations or personal property; (ii) Sublessee shall be entitled only to a proportionate abatement of minimum rent to the extent Sublessor receives a corresponding abatement of rent under the Amended Master Lease during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Sublease and not occupied by Sublessee as a result thereof; (iii) Sublessee shall not, by reason thereof, have a right to terminate this Sublease unless Sublessor has the corresponding

right to terminate the Amended Master Lease in such circumstance or unless the Amended Master Lease shall be otherwise terminated; and (iv) Sublessor reserves the right to terminate the Amended Master Lease and this Sublease in connection with any right granted to it under the Amended Master Lease for an event of casualty or eminent domain whether or not the Premises is damaged or the subject of a taking.
