Sublandlord makes no representations or warranties whatsoever with respect to the condition of the Subleased Premises or the building systems serving the Subleased Premises. In entering into this Sublease, Subtenant has not relied upon or been induced by any statement or representation regarding the condition or suitability of the Subleased Premises other than those, if any, set forth in this Sublease. Notwithstanding the foregoing, Sublandlord shall perform the following work at its sole cost prior to the Sublease Commencement Date ( “Sublandlord’s Work ”): Sublandlord shall cause the water supply and drain in the kitchen located in the Subleased Premises to be in good working order and Sublandlord shall repair or replace as necessary the lock on the door to the rear entrance to the Subleased Premises.

(b) Notwithstanding the foregoing, Sublandlord shall make available for the performance of Subtenant’s Work (as hereinafter defined) an allowance (the “ Subtenant Allowance ”) in an amount equal to the product of (a) Six and 00/100 Dollars ($6.00) multiplied by (b) the number of square feet of rentable area comprising the Subleased Premises, or Forty-Two Thousand Five Hundred Eighty-Two and 00/100 Dollars ($42,582.00).

(c) Subtenant shall improve the Subleased Premises in accordance with the Subtenant’s Plans (as hereinafter defined).

In the event of an assignment by Sublandlord of its interest in the Lease, Sublandlord shall transfer the Security Deposit to the assignee and shall provide Subtenant with a written notice indicating the name and address of the assignee.

(b) Sublandlord and Subtenant each hereby agree to exercise all reasonable commercial diligence to have included in each of its hazard insurance policies pertaining to the Subleased Premises and the property therein, against loss, damage or destruction by fire or other casualty therein covered a waiver of the insurer’s right of subrogation against the other party, or, if such waiver should be unattainable or unenforceable, (i) an express agreement that such policy shall not be invalidated if the insured waives, before the casualty, the right of recovery against any party responsible for a casualty covered by the policy or (ii) any other form of permission for the release of the other party. If such waiver, agreement or permission shall not be, or shall cease to be, obtainable (A) without additional charge, or (B) at all, the insured party shall so notify the other party promptly after learning thereof. In the first such case, if the other party shall so elect and shall pay the insurer’s additional charge therefor, such waiver, agreement or permission shall be included in the policy. Each party hereby releases the other party with respect to any claim (including a claim for negligence) which it might otherwise have against the other party for loss, damage or destruction with respect to the releasing party’s property occurring during the Sublease Term to the extent to which the releasing party is insured and receives proceeds under a policy or policies containing a waiver of subrogation or permission to release liability, as provided in this Section 10(b). If, notwithstanding the recovery of insurance proceeds by either party for such loss, damage or destruction of its property, the other party is liable to the first party with respect thereto or is obligated under this Sublease to make replacement, repair or restoration or payment, then (provided the first party’s right of full recovery under its insurance policies is not thereby prejudiced or otherwise adversely affected) the amount of the net proceeds of the first party’s insurance against such loss, damage or destruction shall be offset against the second party’s liability to the first party therefor, or shall be made available to the second party to pay for replacement, repair or restoration, as the case may be. Nothing contained in this Section 10(b) shall relieve either party of any duty imposed elsewhere in this Sublease to repair, restore or rebuild the leasehold improvements and alterations in the Subleased Premises.

11. Indemnification . Subtenant hereby indemnifies and holds Sublandlord harmless from and against any and all costs, damages, claims, liability, causes of action, suits, judgments and expenses (including reasonable attorney’s fees, disbursements, and actual costs), losses and court costs suffered by or claimed against Sublandlord, directly or indirectly, for death, bodily injury or property damage to the extent based on or arising wholly or substantially out of any negligent acts or omissions of Subtenant or its agents and in respect of all costs, damages, expenses and liabilities incurred by or asserted against Sublandlord in connection with or arising out of all such claims, liability and/or suits, including court costs, reasonable attorneys’ fees and the other expenses of any action, proceeding or suit pertaining thereto, except to the extent attributable to the grossly negligent acts or omissions of the Sublandlord or its agents. In addition, Subtenant hereby indemnifies and holds Sublandlord harmless from and against any and all actual out of pocket attorneys’ fees and expenses incurred in connection with negotiating this Sublease in the event that the Subleased Premises are recaptured by Landlord pursuant to the terms of the Lease.

(iii) the Subleased Premises shall not, without the prior written consent of Sublandlord and Landlord, be occupied by any persons other than Subtenant or its permitted assigns or subtenants (except their respective guests or invitees, on an incidental, non-continuing basis), or be used for any purpose or by any persons other than those permitted hereunder, or if Subtenant shall enter into or purport to enter into any assignment, subletting or other transfer. Notwithstanding the foregoing, Subtenant shall have the right to permit the Named Affiliates to occupy the Subleased Premises so long as the Named Affiliates are under common control with Subtenant.

(iv) Subtenant’s interest in this Sublease or the balance of the leasehold interest created by this Sublease, or any material portion of the goods and chattels of Subtenant, shall at any time be seized in execution, attachment or by other judicial process; provided that no such execution, attachment or other judicial process shall constitute a Default if Subtenant shall, contemporaneously with such execution, attachment or other judicial process, provide Sublandlord with evidence reasonably satisfactory to Sublandlord that Subtenant will be able to continue to perform all of Subtenant’s obligations hereunder when and as required;

(d) Each of Sublandlord and Subtenant agrees to and does hereby waive trial by jury in any action, proceeding or counterclaim brought by either of them against the other in respect of any matters arising out of or in any way connected with this Sublease, the relationship of sublandlord and subtenant, Subtenant’s use or occupancy of the Subleased Premises, any claim of injury or damage, or any statutory remedy. Subtenant hereby represents and acknowledges that neither Sublandlord, nor any broker or agent, has represented or otherwise indicated that Sublandlord under any circumstances whatsoever will not seek to enforce this waiver of jury trial.

Sublandlord shall have no obligation to provide notice to Subtenant to remove any such alterations. In the event that Subtenant fails to surrender the Subleased Premises when and in the condition required by this Sublease, Subtenant hereby irrevocably agrees that Sublandlord shall have the right, in its sole discretion, to pursue any legal processes then available to Sublandlord to evict Subtenant from the Subleased Premises.

Subtenant, as a tenant at sufferance, shall be subject to all of the conditions and covenants of this Sublease as though the tenancy had originally been a monthly tenancy. During the holdover period, each party hereto shall give to the other at least thirty (30) days’ written notice to quit the Subleased Premises, except in the event of nonpayment of monthly installments of Rent when due, or of the breach of any other covenant by Subtenant, in which event Subtenant shall not be entitled to any notice to quit, the usual thirty (30) days’ notice to quit being expressly waived.

16. Relationship to Lease .

(a) Subject to Section 16(b) of this Sublease, notwithstanding anything to the contrary in this Sublease, in the event that the Lease is terminated prior to its scheduled expiration date, this Sublease shall thereupon immediately terminate.

(b) Sublandlord hereby agrees not voluntarily to permit any termination of the Lease (except as a result of casualty or condemnation or other rights Sublandlord has in the Lease to terminate the same). This Section 16(b) shall not apply to any modifications to rules and regulations (including parking rules and regulations) as may be promulgated from time to time.

(c) Subtenant acknowledges that it has received and reviewed the Lease (redacted to delete certain business or confidential terms). Subtenant’s rights pursuant to this Sublease are subject and subordinate at all times to the Lease and to all of the terms, covenants, and agreements of the Lease, except as expressly modified by this Sublease. Subtenant shall not do or permit anything to be done in, or in connection with Subtenant’s use or occupancy of, the Subleased Premises, which would violate any of the unredacted terms, covenants, or agreements of the Lease. Except as modified hereby, Subtenant covenants and agrees to perform, observe and fulfill all of Sublandlord’s unredacted obligations, duties, undertakings, and covenants under the Lease which relate to the Subleased Premises and Subtenant’s rights hereunder. Except as modified hereby, except for any provisions of this Sublease which conflict with the Lease (in which case the provisions of this Sublease shall control as between Sublandlord and Subtenant) and except as provided below, Sublandlord shall have the same obligations to Subtenant and rights of Landlord against Subtenant with respect to this Sublease, as the “Landlord” has with respect to and against the “Tenant” pursuant to the Lease, and Subtenant shall have the same obligations to Sublandlord and rights of Tenant against Sublandlord with respect to this Sublease, as the “Tenant” has with respect to and against the “Landlord” pursuant to the Lease. Sublandlord may enforce directly against Subtenant any of the rights and remedies granted to Landlord pursuant to the Lease. The foregoing notwithstanding, the provisions of the Lease described on Exhibit D attached hereto shall not be applicable to this Sublease. Sublandlord may enforce directly against Subtenant any of the rights and remedies granted to Landlord pursuant to the Lease. Nothing in this Sublease shall be construed or interpreted to grant any greater rights than Sublandlord has received as Tenant from Landlord pursuant to the Lease.

(d) If Subtenant desires to take an action which, under the applicable provisions of the Lease, requires the approval or consent of Landlord, then Subtenant shall not take such action until Landlord has provided its approval or consent in connection therewith.

17. Subleasing and Assignment . Subtenant shall not assign this Sublease or sub-sublease all or any portion of the Subleased Premises without the prior written consent of Sublandlord, which consent may be withheld in the sole and absolute discretion of Sublandlord. Any attempt by Subtenant to assign this Sublease or sub-sublease all or any portion of the Subleased Premises without the prior written consent of Sublandlord shall be void ab initio and shall be deemed null, void and ineffective.

18. Sublease Consent . The parties acknowledge and agree that the Lease provides that Sublandlord’s ability to sublet the Subleased Premises is subject to the consent of the Landlord, and therefore, a condition to the effectiveness of this Sublease is that the Landlord execute and deliver the Sublease Consent in a form reasonably satisfactory to Sublandlord. Sublandlord shall use reasonable efforts to obtain such consent, and Subtenant shall reasonably cooperate with Sublandlord in connection with those efforts, including, without limitation, promptly delivering such financial and other information and documentation that Landlord reasonably requests. If, notwithstanding such reasonable efforts, Landlord does not execute a Sublease Consent in form reasonably satisfactory to Sublandlord by March 18 , 2010 this Sublease shall be null and void and of no further effect, in which case Sublandlord and Subtenant shall promptly return to one another any items or funds delivered to the other pursuant to this Sublease, and neither shall have any further obligations to the other hereunder. Sublandlord will request that Landlord incorporate into the Sublease Consent Landlord’s agreement to recognize this Sublease as a direct lease between Landlord and Subtenant in the event of the termination of the Lease prior to its scheduled expiration date. Subtenant acknowledges and agrees that the effectiveness of this Sublease shall not be contingent on Landlord’s agreement to recognize the Sublease as a direct lease in the event of the termination of the Lease prior to its scheduled expiration date.

19. Brokers . Sublandlord and Subtenant each represents and warrants to the other that it has not dealt with any broker or finder in connection with this Sublease, other than CBRE and Jones Lang LaSalle (“ Broker ”).
