11. Compliance With Nondiscrimination Regulations:
It is understood that it is illegal for Sublessor to refuse to display or
sublease the Subleased Premises, or to assign, surrender or sell the Master

12. Toxic Contamination Disclosure:
Sublessor and Sublessee each acknowledge that they have been advised that
numerous federal, state, and/or local laws, ordinances and regulations ("Laws")
affect the existence and removal, storage, disposal, leakage of and
contamination by materials designated as hazardous or toxic ("Toxics"). Many
materials, some utilized in everyday business activities and property
maintenance, are designated as hazardous or toxic.

Some of the Laws require that Toxics be removed or cleaned up by landowners,
future landowners or former landowners without regard to whether the party
required to pay for "clean up" caused the contamination, owned the property at
the time the contamination occurred or even knew about the contamination. Some
items, such as asbestos or PCBs, which were legal when installed, now are
classified as Toxics, and are subject to removal requirements. Civil lawsuits
for damages resulting from Toxics may be filed by third parties in certain
circumstances.

Sublessor and Sublessee each acknowledge that Broker has no specific expertise
with respect to environmental assessment or physical condition of the Subleased
Premises, including, but not limited to, matters relating to: (i) problems which
may be posed by the presence or disposal of hazardous or toxic substances on or
from the Subleased Premises, (ii) problems which may be posed by the Subleased
Premises being within the Special Studies Zone as designated under the
Alquist-Priolo Special Studies Zone Act (Earthquake Zones), Section 2621-2630,
inclusive of California Public Resources Code, and (iii) problems which may be
posed by the Subleased Premises being within a HUD Flood Zone as set forth in
the U.S. Department of Housing and Urban Development "Special Flood Zone Area
Maps," as applicable.


                                                                        rev 7/95

                                   SUBLEASE
================================================================================

Sublessor and Sublessee each acknowledge that Broker has not made an independent
investigation or determination of the physical or environmental condition of the
Subleased Premises, including, but not limited to, the existence or nonexistence
of any underground tanks, sumps, piping, toxic or hazardous substances on the
Subleased Premises. Sublessee agrees that it will rely solely upon its own
investigation and/or the investigation of professionals retained by it or
Sublessor, and neither Sublessor nor Sublessee shall rely upon Broker to
determine the physical and environmental condition of the Subleased Premises or
to determine whether, to what extent or in what manner, such condition must be
disclosed to potential sublessees, assignees, purchasers or other interested
parties.

<PAGE>
 
                  2. Representations. Tenant hereby represents and warrants to
Landlord that:

                     a.  Master Lease. The Master Lease attached hereto as

Exhibit A is a true and correct copy of the Master Lease, and there exist no
---------

                         ----------
enforcement of the Master Lease by Landlord, and Landlord is not, as of the date
of Tenant's execution hereof, in default in the performance of the Master Lease,
nor has Landlord committed any breach thereof, nor has any event occurred which,

                     -----------
to the Master Lease and all of the Master Lease's provisions, covenants and

provisions of the Sublease.

                  5. No Waiver. This Agreement shall not be construed to modify,
                     ---------

conditions in the Master Lease (except as provided in Section 15); (iii) any of
Tenant's obligations under the Master Lease; or (iv) any rights or remedies of
Landlord under the Master Lease or to enlarge or increase Landlord's obligations
or Tenant's rights under the Master Lease.

                  6. Not Assignable. This Agreement is personal to Tenant,
                     --------------
Guarantor and Subtenant and may not be assigned by Tenant, Guarantor or
Subtenant. Any attempted assignment in violation of this section shall be void.

release or discharge Tenant from any liability under the Master Lease and Tenant
shall remain liable and responsible for the full performance and observance of
all of the provisions, covenants and conditions set forth in the Master Lease on
the part of Tenant to be performed and observed. The breach or violation of any
provision of the Master Lease by Subtenant shall constitute a default by Tenant
in fulfilling such provision. Tenant shall indemnify Landlord against any

                                      2.

                  8.  Consent to Subsequent Sublease. This Agreement by Landlord
                      ------------------------------
shall not be construed as a consent by Landlord to any future assignment or
subletting either by Tenant or Subtenant. The Sublease may not be assigned,
renewed or extended, nor shall the Premises, or any part thereof, be further
sublet without the prior written consent of Landlord in each instance.

                  9.  Termination. Upon the expiration of the term or earlier
                      -----------
termination of the Master Lease, or upon the surrender of the Premises by Tenant
to Landlord, except as provided in Section 10 below, the Sublease shall
terminate as of the effective date ("Termination Date") of such expiration,
termination or surrender, and Subtenant shall vacate the Premises on or before
the Termination Date. Pursuant to Section 8.1 of the Master Lease, Tenant shall
surrender the Premises to Landlord at the expiration or earlier termination of
the Master Lease in the same condition as when leased, reasonable wear and tear,
damage by fire or other insured casualty excepted. Subtenant shall cooperate
with Tenant in connection with Tenant's performance of its obligations pursuant
to this Section 9. If Tenant fails to surrender the Premises to Landlord in the
condition provided above, Tenant, at Landlord's election, shall be deemed to
have held over in the Premises (in accordance with Section 18.12 of the Master
Lease) until such time as Tenant completes Tenant's obligations under the Master
Lease with respect to the condition in which Tenant is required to surrender to
Landlord possession of the Premises to Landlord.

                  10. Landlord's Election. If the Master Lease expires or
                      -------------------
terminates during the term of the Sublease for any reason, or if Tenant shall
surrender the Master Lease to Landlord, Landlord may elect, in Landlord's sole
discretion, by delivering written notice to Subtenant not later than thirty (30)
days after the Termination Date, to continue the Sublease as a direct lease
between Landlord, as landlord, and Subtenant, as tenant, on the terms and
conditions of the Sublease for either (i) the remaining term of the Sublease or
(ii) such periodic tenancy as Landlord shall select, provided that in no event
shall initial period of the periodic tenancy be in excess of the remaining term
of the Sublease. Upon an election by Landlord pursuant to this section,
Subtenant shall attorn to Landlord. If Landlord elects to continue the Sublease,
in no event shall Landlord be (i) liable to Subtenant for any act or omission by
Tenant, (ii) subject to any offsets or defenses which Subtenant had or might
have against Tenant, (iii) bound by any rent or additional rent or any other
payment which Subtenant may have paid to Tenant, or (iv) bound by any amendment
to the Sublease not consented to in writing by Landlord.

                  11. Continuing Liability. Both Tenant and Subtenant shall be
                      --------------------
liable for all bills rendered by Landlord for charges incurred by or imposed
upon Subtenant for services rendered and materials supplied to the Premises. If
a separate submeter shall be installed to measure utilities furnished to the
Premises, then payment for such installation and the utilities so furnished
shall be made by Subtenant directly to Landlord as and when billed and the


                                      3.
