**5.**  **Rent** **.**





**(a)**  **Base
      Rent** **.** In
      consideration of Tenant’s sublease of the Premises as described in this
      Sublease, Subtenant shall pay Tenant base rent of Nineteen Thousand Four Hundred
      Thirty Nine and 00/100ths Dollars ($19,439.00) per month (“Base Rent”). Such
      Base Rent shall be payable in advance in equal monthly installments commencing
      on the first day of the Term and continuing on the first day of each and every
      month thereafter for the next succeeding months during the balance of the Term.
      If the Term commences on a date other than the first day of a calendar month
      or
      ends on a date other than the last day of a calendar month, monthly rent for
      the
      first month of the Term or the last month of the Term, as the case may be,
      shall
      be prorated based upon the ratio that the number of days in the Term within
      such
      month bears to the total number of days in such month.




Any
      installment of Base Rent or Additional Rent, as defined below, or other charges
      or amounts to be paid by Tenant accruing under the provisions of this Sublease
      that are not paid within five (5) days following Subtenant's receipt of written
      notice by Tenant or Landlord (whichever is sooner), shall be subject to late
      fees and bear interest at the rate of set forth in the Lease for Rent or other
      payments due thereunder, but if such rate exceeds the maximum interest rate
      permitted by law, such rate shall be reduced to the highest rate allowed by
      law
      under the circumstances. All interest or late fees shall be paid by Subtenant
      on
      demand from Tenant or Landlord. Except as otherwise provided herein, Subtenant’s
      covenants to pay the Base Rent and Additional Rent are independent of any other
      covenant, condition, provision or agreement herein contained.





**(b)**  **Additional
      Rent** **.** In
      addition to the Base Rent, Subtenant shall also pay to Tenant additional rent
      at
      times and intervals as required by the Lease, which shall be equal to any
      additional amounts which may be due by the Tenant to the Landlord (excluding
      Base Rent thereunder) (“ **Additional
      Rent** ”)
      during
      the term of this Sublease.





**(c)**  **Payment
      directly to Landlord** .
      Until
      and unless otherwise instructed in writing from Tenant, Subtenant agrees to
      make
      all payments of Base Rent and Additional Rent directly to Landlord, as and
      when
      due hereunder.





**6.**  **Compliance
      with the Lease** **.** Excluding only the payment of Base Rent and Additional Rent, which shall be
      paid
      by Subtenant to or on behalf of Tenant under Section 5 above, the Subtenant
      agrees that, during the Term of this Sublease, it shall comply with all other
      obligations of the Tenant under the Lease and, after notice of Landlord default
      under the Lease from Subtenant, the Tenant shall use commercially reasonable
      efforts to ensure Landlord’s cure of such default.





**7.**  **Utilities** **.** Subtenant
      shall pay all costs of utilities services provided to the Premises. Tenant
      shall
      not be responsible for any damages caused by loss of utilities for any period
      of
      time.





**8.**  **Repair
      and Maintenance** **.** Subtenant
      shall, at its sole expense, keep and maintain the Premises as required by the
      Lease. If Subtenant shall fail to so keep and maintain, Tenant may, after notice
      to Subtenant and opportunity to cure (which cure period shall no less than
      thirty (30) days or such longer period as may be reasonably necessary to effect
      a cure), make such repairs, maintenance or cleaning or take other necessary
      action for Subtenant’s account, and the reasonable expense thereof shall be
      payable by Subtenant to Tenant within ten (10) days after written notice
      thereof. Any damage caused or repairs or maintenance necessary with respect
      to
      the Premises by excessive wear and tear resulting from the operation of the
      business of the Subtenant, or from willful or negligent acts on the part of
      the
      Subtenant, its employees, agents, invitees, or contractors, shall be the
      responsibility of Subtenant and Subtenant shall reimburse Tenant for any expense
      incurred in connection therewith.

**9.**  **Alterations
      and Improvements by Subtenant** **.** Subtenant may not make any material alterations, additions or improvements
      to
      the Premises without first obtaining the written consent of Tenant.





**10.**  **Use
      of Parking Facilities** **.** The
      Subtenant shall comply with all conditions contained in the Lease related to
      the
      parking area adjacent to the building.





**11.**  **Assignment
      or Subletting** **.** The
      Subtenant may not assign or hypothecate this Sublease or sublet the Premises
      or
      any part hereof, whether by voluntary act, operation of law, or otherwise,
      without the prior written consent of the Tenant in each instance. No assignment
      shall release the Subtenant of any of its obligations under this Sublease.





**12.**  **Compliance
      with Laws** **:** In
      the
      event of any approved construction or remodeling, **** Subtenant
      shall ensure that any such activities and the Premises and its business
      operations thereon are done in a manner that complies with all applicable laws,
      ordinances, rules and regulations of the city, county, state and federal
      government and any department thereof. Subtenant will not permit the Premises
      to
      be used for any unlawful purpose, and will protect the Tenant and save Tenant
      and the Premises harmless from any and all fines and penalties that may result
      from or be due to any infractions of or non-compliance with such laws,
      ordinances, rules and regulations.

      act or neglect of any other person or caused in any other manner
      whatsoever.





**14.**  **Insurance

      this
      Sublease or any extension hereof, Subtenant will carry and maintain all
      insurance required to be carried by Tenant under the Lease, and shall name
      Tenant as an additional insured thereunder. Tenant shall not be responsible
      or
      liable to the Subtenant for any loss or damage that may be occasioned or caused
      by the acts or omissions of any persons whatsoever. Subtenant will furnish
      to
      Tenant an insurance certificate showing compliance with the above requirements.
      Any such coverage shall be deemed primary to any insurance coverage secured
      by
      Tenant.





**15.**  **Indemnification** **.** Subtenant agrees to indemnify and save Tenant harmless against and from any
      and
      all claims, loss, damage and expense by or on behalf of any person or persons,
      firm or firms, corporation or corporations, arising from any breach or default
      on the part of Subtenant in the performance of any covenant or agreement on
      the
      part of Subtenant to be performed pursuant to the terms of this Sublease or

**16.**  **Default
      by Subtenant** **.** The
      occurrence of any of the following during the Term of this Sublease will be
      an
      event of default:





a.  Subtenant
      fails to pay any installment of Base Rent, or Additional Rent or any other
      allowed charge, when the same is due and it remains unpaid for a period of
      five
      (5) days following receipt of written notice by Subtenant from Tenant;
      or





b.  Subtenant
      fails to comply with any other provision of this Sublease, and does not cure
      such noncompliance within thirty (30) days of Tenant’s written notice to
      Subtenant of such noncompliance, or such longer period as may be reasonably
      necessary to effect a cure given the nature of such noncompliance, but in no
      event more than sixty (60) days; or





c.  Subtenant
      files or has filed against it or any guarantor of this Sublease any bankruptcy
      or other creditor’s action, or makes an assignment for the benefit of its
      creditors.





Upon
      the
      occurrence of an event of default beyond any applicable notice and cure periods,
      Tenant may elect, upon ten (10 days’ written notice to Subtenant, either (i) to
      cancel and terminate this Sublease, or (ii) to terminate Subtenant's right
      to
      possession only without canceling and terminating this Sublease. Notwithstanding
      the fact that initially Tenant elects under (ii) above to terminate Subtenant's
      right to possession only, Tenant will have the continuing right to cancel and
      terminate this Sublease upon five (5) days notice to Subtenant of such further
      election, and will have the right to pursue any remedy of law or in equity
      that
      may be available to Tenant. In the event of election under (ii) above to
      terminate Subtenant's right to possession only, Tenant, at its option, may
      enter
      into and take possession of the Premises without such entry and possession
      terminating this Sublease, or releasing Subtenant, in whole or in part, from
      Subtenant's obligations to pay the Rent and any other charges provided for
      herein. Upon and after entering into possession without termination of the
      Sublease, Tenant may remove all persons and property from the Premises, and
      such
      property may be stored in a public warehouse or elsewhere at the cost and for
      the account of Subtenant, without Tenant becoming liable for any loss or damage
      which may be occasioned thereby. Upon such re-entry, Subtenant will be liable
      to
      Tenant:





a.  For
      the
      immediate payment of all unpaid installments of Rent and other unpaid sums
      that
      were due prior to such re-entry;





b.  For
      the
      installments of Rent and other sums due pursuant to the provisions of this
      Sublease for the periods after re-entry, less any rents paid to Tenant
      thereafter, if any; and


4





c.  For
      all
      reasonable expenses, including advertising expenses, brokerage fees, attorneys'
      fees, and costs of repairs, which will be payable as they are
      incurred.





No
      re-entry or taking possession of the Premises by Tenant will be construed as
      an
      election on its part to terminate this Sublease unless a written notice of
      such
      intention be given to Subtenant, or unless the termination thereof be decreed
      by
      a court of competent jurisdiction.





Except
      as
      provided by law, all rights and remedies of the parties herein enumerated shall
      be cumulative and are not intended to be exclusive of any other remedies or
      means of redress to which such party may be lawfully entitled in case of any
      breach or threatened breach of the other party of any provision of this
      Sublease. The failure of either party to insist in any one or more cases upon
      the strict performance of any of the covenants of this Sublease or to exercise
      any option herein contained shall not be construed as a waiver or relinquishment
      for the future of such covenant or option. A receipt by Tenant of rent with
      knowledge of the breach of any covenant hereof (other than breach of the
      obligation to pay the portion of such rent paid) shall not be deemed a waiver
      of
      such breach, and no waiver by either party of any provisions of this Sublease
      shall be deemed to have been made unless expressed in writing and signed by
      such
      party. In addition to other remedies in this Sublease provided, the parties
      shall be entitled to all other remedies available at law or in equity, including
      but not limited to the restraint by injunction of the violation or attempted
      or
      threatened violation of the covenants, conditions and provisions of this
      Sublease.





**17.**  **Eminent
      Domain** **.**   If
      the
      whole or any portion of the Premises is taken by eminent domain, or conveyance
      in lieu thereof is made (a “Taking”), the terms of the Lease shall control as to
      Subtenant’s continuing rights in the Premises and any adjustment to the Rent due
      hereunder, and Tenant hereby assigns to Subtenant any of its rights thereunder
      relating to issues of eminent domain of the Premises.





**18.**   **Mechanic’s
      Liens** **.** The
      Subtenant hereby covenants and agrees that the Subtenant will not permit or
      allow any mechanic's or materialman's liens to be placed on the Tenant's
      interest in the Premises during the term hereof.





**19.**  **Tenant’s
      Access** **.** Tenant,
      its employees, and its agents shall have the right to enter the Premises at
      all
      reasonable times with reasonable advance notice for the purpose of inspecting,
      repairing, altering, or improving the Premises or the building or, in the last
      three months of this Sublease, to exhibit the Premises to prospective tenants,
      purchasers, or others.





**20.**   **Notices** **.** All
      communications, demands, notices, or objections permitted or required to be
      given or served under this Sublease shall be in writing and shall be deemed
      to
      have been duly given or served if delivered in person to the other party or
      its
      duly authorized agent or three (3) days after deposited in the United States
      mail, postage prepaid, first class mail, and addressed to the other party to

      specifying with particularity the extent and nature of such amendment,
      modification, or waiver. Any waiver by any party of any default of another

      that, upon Subtenant's timely payment of the rent required under this sublease
      and subtenant’s timely performance of all of the other terms and conditions of

      enjoyment of the Premises shall not be disturbed by Tenant. At the expiration
      of
      the term hereunder (as the same may be extended hereby), whether by lapse of
      time or otherwise, Subtenant shall surrender the Premises in the condition

      the event Subtenant remains in possession of the Premises after the expiration

      it
      shall be deemed to be occupying the Premises as a tenant from month-to-month
      basis, subject to all the other conditions, provisions and obligations of this
      Lease insofar as the same are applicable to a month-to-month tenancy and
      Subtenant shall be liable to Tenant for all costs and expenses as may be

      parties hereto acknowledge that this Sublease is subject to Landlord’s consent
