     7.   MASTER LEASE

          7.1  Sublessor is the lessee of the Premises by virtue of a lease,
hereinafter the "MASTER LEASE", a copy of which is attached hereto marked
Exhibit 1, wherein PAFCO LP, a California Limited Partnership is the Lessor,
hereinafter the "MASTER LESSOR".

          7.2  This Sublease is and shall be at all times subject and
subordinate to the Master Lease.

          7.3  The terms, conditions and respective obligations of Sublessor
and Sublessee to each other under this Sublease shall be the terms and
conditions of the Master Lease except for those provisions of the Master Lease
which are directly contradicted by this Sublease in which event the terms of
this Sublease document shall control over the Master Lease. Therefore, for the
purposes of this Sublease, wherever in the Master Lease the word "Lessor" is
used it shall be deemed to mean the Sublessor herein and wherever in the Master
Lease the word "Lessee" is used it shall be deemed to mean the Sublessee herein.

          7.4  During the term of this Sublease and for all periods subsequent
for obligations which have arisen prior to the termination of this Sublease,
Sublessee does hereby expressly assume and agree to perform and comply with,
for the benefit of Sublessor and Master Lessor, each and every obligation of
Sublessor under the Master Lease except for the following paragraphs which are
excluded therefrom: see paragraphs 13, 14 of this document.

          7.5  The obligations that Sublessee has assumed under paragraph 7.4
hereof are hereinafter referred to as the "SUBLESSEE'S ASSUMED OBLIGATIONS".
The obligations that Sublessee has not assumed under paragraph 7.4 hereof are
hereinafter referred to as the "SUBLESSOR'S REMAINING OBLIGATIONS".

          7.6  Sublessee shall hold Sublessor free and harmless from all
liability, judgments, costs, damages, claims or demands, including reasonable
attorney's fees, arising out of Sublessee's failure to comply with or perform

Master Lease without the fault of its sublessor, and to comply with or perform
Sublessor's Remaining Obligations and to hold Sublessee free and harmless from
all liability, judgments, costs, damages, claims or demands arising out of
Sublessor's failure to comply with or perform Sublessor's Remaining Obligations.

     7.8  Sublessor represents to Sublessee that the Master Lease is in full
force and effect and that no default exists on the part of any Party to the
Master Lease.

  8. ASSIGNMENT OF SUBLEASE AND DEFAULT.

     8.1  Sublessor hereby assigns and transfer to Master Lease the Sublessor's
interest in this Sublease, subject however to the provisions of Paragraph 8.2
hereof.

     8.2  Master Lessor, by executing this document, agrees that until a Default
shall occur in the performance of Sublessor's Obligations under the Master
Lease, that Sublessor may receive, collect and enjoy the Rent accruing under
this Sublease. However, if Sublessor shall Default in the performance of its
obligations to Master Lessor then Master Lessor may, at its option, receive and
collect, directly from Sublessee, all Rent owing and to be owed under this
Sublease. Master Lessor shall not, by reason of this assignment of the Sublease
nor by reason of the collection of the Rent from the Sublessee, be deemed liable
to the Sublessee for any failure of the Sublessor to perform and comply with
Sublessor's Remaining Obligations.

     8.3  Sublessor hereby irrevocably authorizes and directs Sublessee upon
receipt of any written notice from the Master Lessor stating that a Default
exists in the performance of Sublessor's obligations under the Master Lease,
to pay to Master Lessor the Rent due and to become due under the Sublease.
Sublessor agrees that Sublessee shall have the right to rely upon any such
statement and request from Master Lessor, and that Sublessee shall pay such
Rent to Master Lessor without any obligation or right to inquire as to whether
such Default exists and notwithstanding any notice from or claim from Sublessor
to the contrary and Sublessor shall have no right or claim against Sublessee
for any such Rent so paid by Sublessee.

     8.4  No changes or modifications shall be made to this Sublease without
the consent of Master Lessor.

  9. CONSENT OF MASTER LESSOR.

     9.1  In the event that the Master Lease requires that Sublessor obtain the
consent of Master Lessor to any subletting by Sublessor then, this Sublease
shall not be effective unless, within ten days of the date hereof, Master Lessor
signs this Sublease thereby giving its consent to this Subletting.

     9.2  In the event that the obligations of the Sublessor under the Master
Lease have been guaranteed by third parties then neither this Sublease, nor the
Master Lessor's consent, shall be effective unless, within 10 days of the date
hereof, said guarantors sign this Sublease thereby giving their consent to this
Sublease.

     9.3  In the event that Master Lessor does give such consent then:

          (a)  Such consent shall not release Sublessor of its obligations or
alter the primary liability of Sublessor to pay the Rent and perform and comply
with all of the obligations of Sublessor to be performed under the Master Lease.

          (b)  The acceptance of Rent by Master Lessor from Sublessee or anyone
else liable under the Master Lease shall not be deemed a waiver by Master
Lessor of any provisions of the Master Lease.

          (c)  The consent of this Sublease shall not constitute a consent to
any subsequent subletting or assignment.

          (d)  In the event of any Default of Sublessor under the Master Lease,
Master Lessor may proceed directly against Sublessor, any guarantors or anyone
else liable under the Master Lease or this Sublease without first exhausting
Master Lessor's remedies against any other person or entity liable thereon to
Master Lessor.

          (e)  Master Lessor may consent to subsequent sublettings and
assignments of the Master Lease or this Sublease or any amendments or
modifications thereto without notifying Sublessor or any one else liable under
the Master Lease and without obtaining their consent and such action shall not
relieve such persons from liability.

          (f)  In the event that Sublessor shall Default in its obligations
under the Master Lease, then Master Lessor, at its option and without being
obligated to do so, may require Sublessee to attorn to Master Lessor in which
event Master Lessor shall undertake the obligations of Sublessor under this
Sublease from the time of the exercise of said option to termination of this
Sublease but Master Lessor shall not be liable for any prepaid Rent nor any
Security Deposit paid by Sublessee, nor shall Master lessor be liable for any
other Defaults of the Sublessor under this Sublease.

     9.4  The signatures of the Master Lessor and any Guarantors of Sublessor at
the end of this document shall constitute their consent to the terms of this
Sublease.

     9.5  Master Lessor acknowledges that, to the best of Master Lessor's
knowledge, no Default presently exists under the Master Lease of obligations to
be performed by Sublessor and that the Master Lease is in full force and
effect.

     9.6  In the event that Sublessor Defaults under its obligations to be
performed under the Master Lease by Sublessor, Master Lessor agrees to deliver
to Sublessee a copy of any such notice of default. Sublessee shall have the
right to cure any Default of Sublessor described in any notice of default
within ten days after service of such notice of default on Sublessee. If such
Default is cured by Sublessee then Sublessee shall have the right of
reimbursement and offset from and against Sublessor.

  10. BROKERS FEE.

     10.1 Upon execution hereof by all parties, Sublessor shall pay to the
Seeley Company a licensed real estate broker, ("Broker"), a fee as set forth
in a separate agreement between Sublessor and Broker, or in the event there is
no such separate agreement, the sum of $_____________________________ for
brokerage services rendered by Broker to Sublessor in this transaction.

     10.2 Sublessor agrees that if Sublessee exercises any option or right of
first refusal as granted by Sublessor herein, or any option or right
substantially similar thereto, either to extend the term of this Sublease, to
renew this Sublease, to purchase the Premises, or to lease or purchase adjacent
property which Sublessor may own or in which Sublessor has an interest, then
Sublessor shall pay to Broker a fee in accordance with the schedule of Broker
in effect at the time of the execution of this Sublease. Notwithstanding the
foregoing, Sublessor's obligation under this Paragraph 10.2 is limited to a
transaction in which Sublessor is acting as a Sublessor, lessor or seller.

     10.3 Master Lessor agrees that if Sublessee shall exercise any option or
right of first refusal granted to Sublessee by Master Lessor in connection with
this Sublease, or any option or right substantially similar thereto, either to
extend or renew the Master Lease, to purchase the Premises or any part thereof,
or to lease or purchase adjacent property which Master Lessor may own or in
which Master Lessor has an interest, or if Broker is the procuring cause of any
other lease or sale entered into between Sublessee and Master Lessor pertaining
to the Premises, any part thereof, or any adjacent property which Master Lessor
owns or in which it has an interest, then as to any of said transactions,
Master Lessor shall pay to Broker a fee, in cash, in accordance with the
schedule of Broker in effect at the time of the execution of this Sublease.

     10.4 Any fee due from Sublessor or Master Lessor hereunder shall be due
and payable upon the exercise of any option to extend or renew, upon the
execution of any new lease, or, in the event of a purchase, at the close of
escrow.

     10.5 Any transferee of Sublessor's interest in this Sublease, or of Master
Lessor's interest in the Master Lease, by accepting an assignment thereof,
shall be deemed to have assumed the respective obligations of Sublessor or
Master Lessor under this Paragraph 10. Broker shall be deemed to be a
third-party beneficiary of this paragraph 10.

  11.     ATTORNEY'S FEES. If any party or the Broker named herein brings an
action to enforce the terms hereof or to declare rights hereunder, the
prevailing party in any such action, on trial and appeal, shall be entitled to
his reasonable attorney's fees to be paid by the losing party as fixed by the
Court.

  12.     ADDITIONAL PROVISIONS. [If there are no additional provisions, draw
a line from this point to the next printed word after the space left here. If
there are additional provisions place the same here.]

13.  Sublessee shall take the premises in an "as-is" condition. Sublessee
shall not be responsible for the existing condition of the premise should any
restoration be required by the Master Lessor at the expiration of the sublease.
Except as in 6.2 above.

14.  Sublessee shall pay no common area operating expenses as referenced in the
Master Lease or real property taxes, as mentioned in Master Lease.
