Acts of maintenance, preservation or efforts to lease the Premises or the appointment of a receiver upon application of Landlord to protect Landlord's interest under this Lease shall not constitute an election to terminate Tenant's right to possession.

Upon such termination, in addition to any other rights and remedies to which Landlord may be entitled under applicable law, Landlord shall be entitled to recover from Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts which had been earned at the time of termination, (2) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such Rent loss that the Tenant proves could be reasonably avoided; (3) the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of such Rent loss that the Tenant proves could be reasonably avoided; and (4) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant's failure to perform Tenant's obligations under this Lease or which, in the ordinary course of things, would be likely to result therefrom. The "worth at the time of award" of the amounts referred to in (1) and (2), above shall be computed at the lesser of the "prime rate," as announced from time to time by Wells Fargo, N.A. (San Francisco) plus five (5) percentage points, or the maximum interest rate allowed by law ("Applicable Interest Rate"). The "worth at the time of award" of the amount referred to in (3) above shall be computed by discounting such amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco at the time of the award plus one (1%) percent.

D. LATE CHARGE. If any installment of Rent is not paid within five (5) business days from the date when due, such amount shall bear interest at the Applicable Interest Rate from the date on which said payment shall be due until the date on which Landlord shall receive said payment. In addition, Tenant shall pay Landlord a late charge equal to five (5%) percent of the delinquency, to compensate Landlord for the loss of the use of the amount not paid and the administrative costs caused by the delinquency, the parties agreeing that Landlord's damage by virtue of such delinquencies would be difficult to compute and the amount stated herein represents a reasonable estimate hereof. This provision shall not relieve Tenant of Tenant's obligation to pay Rent at the time and in the manner herein specified. E. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of the parties are <PAGE> 22 cumulative and not alternative, to the extent permitted by law and except as otherwise provided herein. LIENS 27. Tenant shall keep the Premises free from liens arising out of or related to work performed, materials or supplies furnished or obligations incurred by Tenant or in connection with work made, suffered or done by or on behalf of Tenant in or on the Premises or Project. In the event that Tenant shall not, within ten (10) business days following the imposition of any such lien, cause the same to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided herein and by law, the right, but not the obligation, to cause the same to be released by such means as Landlord shall deem proper, including payment of the claim giving rise to such lien. All sums paid by Landlord on behalf of Tenant and all expenses incurred by Landlord in connection therefor shall be payable to landlord by Tenant on demand with interest at the Applicable Interest Rate.

TRANSFERS BY 28. In the event of a sale or conveyance by Landlord of the LANDLORD Building or the Project or a foreclosure by any creditor of Landlord, the same shall operate to release Landlord from any liability upon any of the covenants or conditions, express or implied, herein contained in favor of Tenant, to the extent required to be performed after the passing of title to Landlord's successor-in-interest. In such event, Tenant agrees to look solely to the responsibility of the successor-in-interest of Landlord under this Lease with respect to the performance of the covenants and duties of "Landlord" to be performed after the passing of title to Landlord's successor-in-interest. This Lease shall not be affected by any such sale and Tenant agrees to attorn to the purchaser or assignee.

All sums, so paid by Landlord and all necessary incidental costs together with interest thereon at the Applicable Interest Rate from the date of such payment by Landlord shall be payable to Landlord on demand, and Tenant covenants to pay such sums, and Landlord shall have, in addition to any other right or remedy of Landlord, the same right and remedies in the event of the non-payment thereof by Tenant as in the case of Default by Tenant in the payment of Base Rent and Basic Operating Cost. WAIVER 30. If either Landlord or Tenant waives the performance of any term, covenant or condition contained in this Lease, such waiver shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition contained herein. The acceptance of Rent by Landlord shall not constitute a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, regardless of Landlord's knowledge of such preceding breach at the time Landlord accepted such Rent. Failure by Landlord to enforce any of the terms, covenants or conditions of this Lease for any length of time shall not be deemed to waive or to decrease the right of Landlord to insist thereafter upon strict <PAGE> 23 performance by Tenant. Waiver by Landlord of any term, covenant or condition contained in this Lease may only be made by a written document signed by Landlord. NOTICES 31.

One of the written notifications shall be delivered to Landlord and the other to Tenant. In the event the two (2) arbitrators of the parties hereto cannot agree on the Base Rent for the Premises herein, said two (2) arbitrators shall appoint a third arbitrator who shall be a licensed real estate broker experienced in the leasing of comparable facilities in the County of San Mateo, to act as an arbitrator.

The third arbitrator shall have no right to adopt a compromise or middle ground or any modification of either of the two final proposed resolutions. The resolution that the third arbitrator chooses as most closely approximating his determination of the Base Rent shall constitute the decision of all arbitrators and shall be final and binding upon the parties. The parties hereto shall pay the charges of the arbitrator appointed by it and any expenses incurred by such arbitrator.
