12.  SUBORDINATION OF SUBLEASE
     -------------------------

     This Sublease is subject and subordinate to the Master Lease, and Subtenant
shall have no greater rights in and to the Subleased Premises than Sublandlord
has as tenant under the Master Lease.

13.  HOLDOVER
     --------

     If Subtenant remains in possession of the Demised Premises after expiration
of this Sublease, Tenant's occupancy shall be a month-to-month subtenancy at
125% of the rental rate applicable to the last month of the unexpired term and
under all the other terms, conditions and provisions hereof except those
pertaining to the term of the Sublease. Subtenant further agrees to indemnify,
defend and hold Sublandlord harmless from and against all claims, demands,
causes of action, losses and other liability of every kind and description
(including, without limitation, reasonable attorneys' fees) that arise from or
relate in any way to Subtenant's possession of the Demised Premises after
expiration of this Sublease.

14.  TERMINATION OF MASTER LEASE
     ---------------------------

     In the event that the Master Lease shall terminate by operation of law or
otherwise, or Master Landlord or Sublandlord as tenant under the Master Lease
cancels or terminates the Master Lease, as expressly provided therein, or in the
event that the Master Landlord shall terminate the Master Lease for any reason,
this Sublease shall thereupon automatically be canceled and terminated, and both
parties hereto shall thereupon be relieved of all further liability hereunder.

     Sublandlord represents to Subtenant that the Master Lease is in full force
and effect, and that no default or event that, with the passing of time or the
giving of notice or both, would constitute a default, exists on the part of
Sublandlord, or, to Sublandlord's knowledge, the Landlord. Sublandlord agrees to
maintain the Master Lease in full force and effect, except to the extent that
any failure to maintain the Master Lease is due to the failure of Subtenant to
comply with any of its obligations under this Sublease.


15.  ENTIRE AGREEMENT
     ----------------

     This Sublease represents the entire agreement between the parties, and
supersedes all prior agreements both written and oral between the parties, and
may be amended only by a written agreement executed by the parties. The terms ,
covenants and conditions of this Sublease shall be binding upon and shall inure
to the benefit of Sublandlord and Subtenant and their respective successors and
permitted assigns.

                                      12.

16.  CONSENT
     -------

     This Sublease is subject to the written consent from the Landlord, and from
Stanford Management Company. In the event that Sublessee desires to take any
action that will require the consent of Landlord, Sublessor shall use reasonable
and diligent efforts to obtain such consent, provided that Sublessor shall not
be liable in any way for the failure of Landlord to so consent. Sublandlord
shall use its best efforts to obtain the consent of the Landlord upon the mutual
execution hereof.

17.  SIGNAGE
     -------

     Subject to the written approval of Landlord and Sublandlord, which approval
shall not be unreasonably withheld or delayed, Subtenant may affix signage to
the front entrance doors of the building they occupy. Any such signage shall be
subject to Landlord's general sign program for the Complex as approved by the
City of Palo Alto and any approval required of Stanford under the Ground Lease.



18.  SECURITY DEPOSIT / LETTER OF CREDIT
     -----------------------------------

     (a) On or before execution of this Sublease, Subtenant shall deliver to
Sublandlord a security deposit in the amount of Eighty Thousand Four Hundred
Seventy Eight ($80,478.00) U.S. Dollars (the "First Security Deposit") to be
used as security for the full and faithful performance of all of  Subtenant's
obligations under this Sublease.  In addition to any and all rights and remedies
Sublandlord may have at law and equity, Sublandlord may, but without obligation
to do so, use all or any portion of the First Security Deposit to compensate
Sublandlord for any and all losses, damages and expenses (including, without
limitation, reasonable attorneys fees and any deficiency in the reletting of the
Demised Premises) incurred before or after any re-entry by Landlord, and
resulting from any failure of Subtenant to timely perform any of its obligations
under the terms of this Sublease, including, without limitation, the obligation
to pay rent.

     (b) In addition to the First Security Deposit, on or before Sublease
execution, Subtenant shall deliver to Sublandlord, as a second security deposit
(the "Second Security Deposit") for the full and faithful performance by
Subtenant of all of its obligations under this Sublease, an irrevocable letter
of credit, in the form attached hereto as Exhibit C running in favor of
Sublandlord issued by a national bank acceptable to Sublandlord in the initial
amount of Nine Hundred Sixty Five Thousand Seven Hundred and Thirty Six
($965,736.00) U.S. Dollars, which amount shall be subject to adjustment from
time to time in accordance with the adjustment schedule which shall be set forth
in said Letter

                                      13.
<PAGE>

of Credit and which schedule shall state the specific dollar amount of each
adjustment and the date said adjustment shall occur, all of which shall be in
accordance with the terms of Subparagraph 18(f) below (the "Letter of Credit").
The Letter of Credit shall be (a) at sight and irrevocable and (b) maintained in
effect, throughout the initial term of this Sublease, with prompt replacement,
renewal or extension covering the period of any extension of said sublease term.
The terms and conditions of the Letter of Credit (and the bank issuing the same
which party is referred to herein as the "Bank") shall be acceptable to
Sublandlord and shall provide, among other things, that (1) Sublandlord, shall
have the right to draw down an amount up to the face amount of the Letter of
Credit upon the presentation to the Bank of Sublandlord's statement that such
amount is due to Sublandlord under the terms and conditions of this Sublease.
Subtenant further covenants and warrants that it will not assign or encumber the
Letter of Credit or any part thereof. If an event of default under the Sublease
occurs, Sublandlord may, but without obligation to do so, use the Second
Security Deposit by presenting the Letter of Credit to the bank accompanied by
Sublandlord's demand to draw down on said Letter of Credit, or any portion
thereof, in an amount not to exceed the amount required to cure the default
and/or to compensate Sublandlord for any and all losses, expenses and damages
sustained by Sublandlord resulting from Subtenant's default (including but not
limited to, reasonable legal and other related expenses, and any deficiency in
reletting the Demised Premises), whether occurring before or after re-entry by
Sublandlord.

     (c) In the event that Sublandlord shall use the Second Deposit as provided
for in the immediately preceding sentence, Subtenant shall, immediately on
demand, deposit with the Bank another Letter of Credit in an amount equal to the
portion of the Second Security Deposit so applied or used so as to replenish the
amount of the Second Security Deposit to the amount that it was immediately
prior to Sublandlord's application of a portion of said security deposit to
Subtenant's default.

     (d) In the event that Sublandlord applies or retains all or any portion of
either or both of the First Security Deposit or the Second Security Deposit
(together referred to as the "Security Deposits") as provided for herein,
Subtenant shall not be deemed to have cured its default which gave rise to the
application or retention of such funds unless Subtenant shall have deposited,
immediately upon demand, with Sublandlord the amount so applied or retained so
that the amount so applied or retained shall be fully replenished and
Sublandlord shall have the full amount of the Security Deposits as set forth
above restored and on deposit at all times during the term of this Sublease.  To
the extent that the Terms of Paragraph 5 of this Sublease incorporate herein by
reference the terms of Paragraph  19 of the Master Lease (the default notice &
cure provisions) the same shall not be applicable to the obligation of Subtenant
to replenish the Security Deposits immediately upon demand.

                                      14.
<PAGE>

     (e) Except as otherwise required by applicable California law, Subtenant
shall not be entitled to, nor Sublandlord liable for, any interest on the first
Security Deposit.

     (f)  Beginning April 30, 2000 and continuing thereafter, so long as
Subtenant is not in default under the terms of this sublease, then thirty (30)
days after the end of each calendar quarter, the Bank shall reduce the amount of
the Letter of Credit by an amount equal to the total amount of basic rent
(excluding operating expenses, taxes, utilities and other charges) paid by
Subtenant under the terms of Paragraph 3 of this sublease for the immediately
preceding calendar quarter. Notwithstanding the forgoing, in no event shall the
Bank reduce the amount of the Letter of Credit if the Bank has received written
notice from Sublandlord stating that Subtenant is in default under the terms of
this sublease. In the event that the Bank receives such a notice of default from
Sublandlord then the Bank shall not take any further action to reduce the amount
of the Letter of Credit unless and until such time as Sublandlord shall send the
Bank written notice stating that the default has been cured by Subtenant or
waived by Sublandlord.

19.  THIRD PARTY RIGHTS
-----------------------

     The benefit of the provisions of this Sublease is expressly limited to
Sublandlord and Subtenant and their permitted successors and assigns.  Under no
circumstance will any third party be construed to have any rights as a third
party beneficiary with respect to any of the provisions contained within this
Sublease.


20.  ADDITIONAL SPACE
     ----------------

     It is understood that the Sublessee is requesting more space in the
building and that the Sublessor will use its best efforts to relocate the
current downstairs occupants to a separate area of the campus to accommodate any
request. The Sublessor will have thirty (30) days to determine if the
Sublessee's request can be accommodated.
