                                    premises to a condition substantially
                                    suitable for their intended use within

                    all rights which the LESSEE may have for damages or injury
                    to the leased premises for any taking by eminent domain,

     BANKRUPTCY                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, 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 obligatons for the payment of money in connection
