(d) The rent and all other sums payable thereunder by TENANT shall be equitably abated from the date of such damage or destruction until the date on which the Casualty Restoration has been completed, unless this lease has sooner terminated as provided herein.

(e) In the case of a taking of all or a substantial portion of the Premises by eminent domain, so that in the TENANT's reasonable opinion the Premises are no longer suitable for their intended use, the TENANT may elect to terminate this lease by written notice to LANDLORD within thirty (30) days notice to LANDLORD within thirty (30) days after TENANT obtains actual notice of such taking. Upon such election to terminate, this lease shall have no further effect. (f) In the case of a taking whereby the TENANT does not elect to terminate this lease, the Rent, Additional Rent and Other sums payable by TENANT under this lease shall be equitably abated. 18. DEFAULT AND BANKRUPTCY In the event that: (a) The TENANT 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 receipt by TENANT of written notice thereof; or (b) The TENANT shall default in the observance or performance of any other of the TENANT's covenants, agreements, or obligations hereunder and such default shall not be corrected within thirty (30) days after written notice thereof or, if such default cannot reasonably be corrected within such thirty (30) day period, if TENANT shall fail, within such period, to commence to cure such default or thereafter to prosecute and complete the same with due diligence; or (c) The TENANT shall be declared bankrupt or insolvent according to law, or, if any assignment shall be made of TENANT's property for the benefit of creditors, then the LANDLORD shall have the right thereafter, while such default continues, to re-enter and take complete possession of the Premises, to declare the term of this lease ended, and remove the TENANT's effects, without prejudice to any remedies which might be otherwise used for arrears of rent or other default. The 5 6 TENANT shall indemnify the LANDLORD against all loss of rent and other reasonable payments which the LANDLORD may incur by reason of such termination during the residue of the term. If the TENANT shall default after reasonable notice thereof, in the observance or performance of any conditions or covenants on TENANT's part to be observed or performed under or by virtue of any of the provisions in any article of this lease, the LANDLORD, 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 TENANT. If the LANDLORD 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 shall be paid to the LANDLORD by the TENANT as additional rent. 19.

WAIVER OF SUBROGATION Any insurance carried by either party with respect to the Premises, the Building or the Land or occurrences thereon shall, if it can be so written without additional premium, or with an additional premium which the other party agrees to pay, include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to the occurrence of the injury or the loss. Each party, notwithstanding other provisions of this lease to the contrary, hereby waives any rights of recovery against the other for injury or loss due to hazards covered by such insurance to the extent of the indemnification received thereunder. 6 7 22. CASUALTY INSURANCE TENANT, at TENANT's sole cost and expense, shall maintain at all times during the term of this lease with respect to the Premises and the Building and property of which such Premises are a part, insurance naming the LANDLORD as insured against loss or damage under a so-called "all risk" type insurance policy.

(The LANDLORD's financial inability to complete improvements is not a delay beyond the LANDLORD's reasonable control). Notwithstanding anything in this paragraph to the contrary, if an event beyond the LANDLORD's reasonable control occurs and the LANDLORD can not deliver the Premises on the Commencement Date, then the TENANT shall have the option of terminating this Lease if the LANDLORD is unable to deliver the Premises to the Tenant in accordance with this Section 23 on or before September 1, 1996. 24.
