      which Sublessor may become obligated by reason of Sublessee's default or breach,
      or for any loss or damage sustained by Sublessor as a result of Sublessee's
      default or breach. If Sublessor so uses any portion of the Security Deposit,
      Sublessee shall, within ten (10) days after written demand by Sublessor, restore

      shall be returned to Sublessee or to the last assignee, if any, of Sublessee’s
      interest hereunder.

              OTHER
                PROVISIONS OF SUBLEASE. 

            


    

    


    Except
      to
      the extent expressly provided for in this Sublease (and any Amendments) to
      the
      contrary (e.g., Term, Commencement Date, size of Premises, Rent, etc.) and
      only
      to the extent that such terms and conditions reasonably apply to the Sublessee
      and the Premises, all
      applicable terms and conditions of the Master Lease are incorporated into and
      made a part of this Sublease as if Sublessor were the lessor thereunder,
      Sublessee the lessee thereunder, and the Premises the Master
      Premises.

    Sublessee
      assumes and agrees to perform the lessee's obligations under the Master Lease
      during the Term to the extent that such obligations are applicable to the
      Premises, except that the obligation to pay rent to Lessor under the Master
      Lease shall
      be
      considered performed by Sublessee to the extent and in the amount rent is paid
      to Sublessor in accordance with Section 6 of this Sublease. Sublessee shall
      not
      commit or suffer any act or omission that will violate any of the provisions
      of
      the Master Lease. Sublessor shall exercise due diligence in attempting to cause
      Lessor to perform its obligations under the Master
      Lease for the benefit of Sublessee. If the Master Lease terminates,
      this
      Sublease shall terminate and the parties shall be relieved of any further
      liability or obligation under this Sublease, provided however, that if the
      Master Lease terminates as
      a
      result of a default or breach by Sublessor or Sublessee under this Sublease
      and/or the Master Lease, then the defaulting party shall be liable to the
      nondefaulting party for the damage suffered as a result of such termination.
      Notwithstanding the foregoing, if the Master Lease gives Sublessor the
      right to
      terminate the Master Lease
      in the
      event of the partial or total damage, destruction, or condemnation of the Master
      Premises or the building or project of which the Master Premises are a part,
      the
      exercise of such right by Sublessor shall not constitute a default or breach
      hereunder. THE PARTIES AGREE THAT IN
      NO
      EVENT SHALL EITHER PARTY BE LIABLE UNDER THIS AGREEMENT FOR ANY SPECIAL,
      EXEMPLARY, PUNITIVE, INDIRECT OR CONSEQUENTIAL DAMAGES (INCLUDING ANY LOST
      PROFIT, REVENUE, BUSINESS OR OTHERWISE); REGARDLESS OF THE THEORY OF RECOVERY,
      WHETHER ALLEGED AS A BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT
      LIABILITY), UNJUST ENRICHMENT OR OTHERWISE, EVEN IF SUCH PARTY HAS BEEN ADVISED
      OF THE POSSIBILITY OF SUCH DAMAGES OR BASED ON THE FAILURE OF THE ESSENTIAL
      PURPOSE OF ANY REMEDY.

      tax, insurance, common area maintenance (CAM’s) and utilities are included
      within the Rent set forth in Section 6 of the Sublease. Sublease shall only
      be
      responsible for its Pro-Rata Share (as defined below) of Sublessor’s operating
      expense (that is, the foregoing expenses as well as other “Operating Expenses”
as defined in the Master Lease) increases above a 2006 base year. Sublessee’s
      Pro-Rata Share is a fraction, the numerator of which is the rentable area of
      the
      Premises (averaged for that Lease Year), which is currently 28,820 square feet.
      Such additional rent shall be payable as and when such operating expenses are
      payable by Sublessor; provided, however, that Sublessor shall be obligated
      to
      provided, fifteenth (15) days prior notice of its due date.

    


    2.  CONFIRMATION
      OF TERMINATION DATE
      Sublessee shall have a one-time right to confirm the Termination Date as set
      forth in Section 5 of the Sublease. Said right shall be exercisable at any
      time
      on or before the end of the twenty forth (24th)
      month
      of the Term. In the event Sublessee exercises said confirmation of the
      Termination Date, the sublease term shall terminate on May 31, 2009. If
      Sublessee doe not exercise its confirmation of the Termination Date, Sublessee
      shall have no further right to terminate and the Sublease Term shall be extended
      for the remainder of the Master Lease term. Said Term shall be an additional
      twenty two (22) months, terminating March 31, 2011. The rental rate for the
      additional term shall be:

     

    
      
        	
                Months

              	
                RSF/Month/Full
                  Service

              
	
                37-48:

              	
                $2.80
                  Fully Serviced

              
	
                49-58:

              	
                $2.90
                  Fully Serviced

              


      



    3.  CONDITION
      OF PREMISES

    Sublessor
      shall deliver the Premises in its existing condition.

    


    4.  OFFICE
      FURNISHINGS Sublessee,
      at no additional cost, shall have the use for the Term but not the ownership
      of
      any currently in-place office furnishings excluding the desk/task chairs.
      Sublessor makes no representations or warranties on the condition of such
      furnishings and Sublessee hereby accepts said furnishings in as-is
      condition.

    


    5.  DEMISING
      OF THE PREMISES
      Sublessor’s obligations pursuant to this paragraph are subject to and contingent
      upon the cost feasibility (in Sublessor’s sole discretion) of the demising of
      the Premises. Sublessor shall not be obligated to demise (separate by wall,
      etc.) the Premises from the remainder of the Master Premises unless and until
      the remained of the Master Premises on the third floor is subleased to another
      tenant(s). Demising, if required, shall be at the sole cost and responsibility
      of the Sublessor and completed per governmental codes. A proposed demising
      plan
      shall be attached to the Sublease upon completion of such plan and Sublease
      agrees to accept said plan and any modifications of its Premises required to
      provide exits and corridors per governmental codes.

    


    Notwithstanding
      the foregoing, if Sublessor elects not to erect such demising walls, Sublessee’s
      square footage shall not be modified from that defined in the Sublease. If
      Sublessor elects to erect such demising walls, (i) such walls shall be erected
      in a good and workmanlike manner, (ii) done in such a manner as to reduce any
      unreasonable interference to Sublessee’s business, (ii) they shall be erected,
      taped, sanded and painted to match the adjacent walls within Sublessee’s
      Premises, (iv) if there is any reduction in the size of the Premises, then
      Sublessee’s pro rata share will be reduced accordingly (however, Sublessee’s pro
      rata portion of common area will increase commensurately) or (v) if there is
      an
      increase in the size of the Premises, Sublessee’s Pro-Rata Share will not be
      adjusted upward.

    



    Amendment
      to Sublease Agreement

    


    6.  BUILDING
      EXERCISE FACILITY
      Sublessee will pay Lessor directly for the use of the exercise facility. The
      exercise facility cost is $5.00 per participating employee per month (or such
      other amount as may be imposed by Lessor). The parties agree that Sublessor
      shall not be responsible for any such payments.

    


    7.  SIGNAGE: Sublessee
      shall have signage rights provided to Sublessor as provided for under the Master
      Lease.

    


    Except
      as
      expressly set forth in this Amendment, the Sublease shall remain in full force
      and effect.
