         municipality,  state or other governmental authority respecting the use

 8.      Lessee shall be responsible for all phone cost.

 9       The individual  executing this lease personally  guarantees payment due
         on this lease in the event of default.

10.      Lessee has  deposited  with Lessor a Security  Deposit in the amount of
         the Monthly Rent.  The Security  Deposit  constitutes  security for the
         faithful  performance  by  Lessee  of  all  the  terms,  covenants  and
         conditions of this Rental Agreement. If Lessee defaults with respect to
         any  provision  of this  Lease,  including,  but not  limited  to,  the
         provisions  relating to the payment of rents,  Lessor may use, apply or
         retain all or any part of the  Security  Deposit for the payment of any
         rent of any  other  sum in  default,  or for the  payment  of any other
         amount which Lessor may spend or become obligated to spend by reason of
         Lessee's default.  If any portion of the Security Deposit is so used or
         applied Lessee shall, upon demand thereof,  deposit cash with Lessor in
         an amount  sufficient  to restore the Security  Deposit to its original
         amount,  and Lessee's  failure to do shall be a material  breach of the
         Rental  Agreement.  Lessor  shall not be required to keep the  Security
         Deposit  separate from its general funds,  and shall not be entitled to
         interest on the Security  Deposit,  the amount of the Security  Deposit
         and other  provisions of this Rental  Agreement having been established
         and negotiated in contemplation of the foregoing. If Lessee shall fully
         perform  every  provision  of the  Lease  to be  performed  by it,  the
         Security  Deposit or any balance thereof shall be returned to Lessee or
         to any assignee to Lessee at the  expiration of the Lease Term and upon
         surrender of the  premises.  In no event shall Lessee have the right to
         apply any part of the Security Deposit to rent due hereunder.  Security
         deposit will be held until property  management assesses any damages to
         the  office and  repairs  are made (i.e.  carpets  cleaned,  and office
         painted, etc.).

11.      In the  event a suit,  action  or other  proceeding  of any  nature  is
         instituted to interpret or enforce any  provision of this  Agreement or
         with respect to any dispute relating to this Agreement,  the prevailing
         party shall be entitled to recover from the losing party its attorneys'
         fees and all other fees,  costs,  and  expenses  actually  incurred and
         reasonable  necessary in  connection  therewith.  In the event of suit,
         action, or other proceeding,  the amount thereof shall be determined by
         the judge,  shall  include fees and expenses  incurred on any appeal or
         review, and shall be in addition to all other amounts provided by law.

         IN WITNESS  WHEREOF,  Lessor  and  Lessee  have  executed  this  Rental
         Agreement as of the day and year first above written.
