                                      loss and damage wherever occurring
                                      occasioned by any omission, fault, neglect
                                      or other misconduct of the LESSEE. The

                                      thereafter within thirty (30) days prior
                                      to the expiration of any such policies.
                                      All such insurance certificates shall

                                      prior written notice to each assured named
                                      therein.

18.  FIRE, CASUALTY --                Should a substantial portion of the leased
     EMINENT DOMAIN                   premises, or of the property of which they
                                      are a part, be substantially damaged by
                                      fire or other casualty, or be taken by
                                      eminent domain, the LESSOR may elect to
                                      terminate this lease. When such fire,
                                      casualty, or taking renders the leased
                                      premises substantially unsuitable for
                                      their intended use, a just and
                                      proportionate abatement of rent shall be
                                      made, and the LESSEE may elect to
                                      terminate this lease if:

                                        (a)   The LESSOR fails to give written
                                              notice within thirty (30) days of
                                              intention to restore leased
                                              premises, or

                                        (b)   The LESSOR falls to restore the
                                              leased premises to a condition
                                              substantially suitable for their
                                              intended use within ninety (90)
                                              days of said fire, casualty or
                                              taking.

                                      The LESSOR reserves, and the LESSEE grants
                                      to the LESSOR, all rights which the LESSEE
                                      may have for damages or injury to the
                                      leased premises for any taking by eminent
                                      domain, except for damage to the LESSEE's
                                      fixtures, property, or equipment.

19.  DEFAULT AND                      In the event that:
     BANKRUPTCY
     (FILL IN)                          (a)   The LESSEE shall default in the
                                              payment of any installment of rent
                                              or other sum herein specified and
                                              such default shall continue for
                                              ten (10) days after written notice
                                              thereof; or

                                        (b)   The LESSEE shall default in the
                                              observance or performance of any
                                              other of the LESSEE's covenants,
                                              agreements, or obligations
                                              hereunder and such default shall
                                              not be corrected within thirty
                                              (30) days after written notice
                                              thereof; or

                                        (c)   The LESSEE shall be declared
                                              bankrupt or insolvent according to
                                              law, or, if any assignment shall
                                              be made of LESSEE's property for
                                              the benefit of creditors,

                                      then the LESSOR shall have the right
                                      thereafter, while such default continues,
                                      to re-enter and take complete possession
                                      of the leased premises, to declare the
                                      term of this lease ended, and remove the
                                      LESSEE's effects, without prejudice to any
                                      remedies which might be otherwise used for
                                      arrears of rent or other default. The
                                      LESSEE shall indemnify the LESSOR against
                                      all loss of rent and other payments which
                                      the LESSOR may incur by reason of such
                                      termination during the residue of the
                                      term. If the LESSEE shall default, after
                                      reasonable notice thereof, in the
                                      observance or performance of any
                                      conditions or covenants on LESSEE's part
                                      to be observed or performed under or by
                                      virtue of any of the provisions in any
                                      article of this lease, the LESSOR, without
                                      being under any obligation to do so and
                                      without thereby waiving such default, may
                                      remedy such default for the account and at
                                      the expense of the LESSEE. If the LESSOR
                                      makes any expenditures or incurs any
                                      obligations for the payment of money in
                                      connection therewith, including but not
                                      limited to, reasonable attorney's fees in
                                      instituting, prosecuting or defending any
                                      action or proceeding, such sums paid or
                                      obligations insured, with interest at the
                                      rate of 18% per cent per annum and costs,
                                      shall be paid to the LESSOR by the LESSEE
                                      as additional rent.
