                                   RECITALS:

         This Sublease is made with reference to the following facts:

         A.       John Arrillaga, Trustee, or his Successor Trustee, UTA dated

Peery, Trustee, or his Successor Trustee, UTA dated 7/20/77 (Richard T. Peery

Agreement, dated as of September 8, 1994 (the "ORIGINAL MASTER LEASE") with
respect to a portion ("ORIGINAL MASTER PREMISES") of that certain one story
office building located at 474 Potrero Drive, Sunnyvale California which portion
consisted of approximately 12,696 square feet of space. The Original Master
Lease was amended by Amendment No. 1 to Lease dated as of October 25, 1996
("FIRST AMENDMENT") which added to the Original Master Premises an additional
9,032 square feet for a total of 21,728 square feet of space which 21,727 square
feet are hereinafter called the "MASTER PREMISES." The Original Master Lease was
further amended by Amendment No. 2 to Lease dated as of March 10, 1998 ("SECOND
AMENDMENT"). The Original Master Lease, the First Amendment and the Second
Amendment are hereinafter collectively called the "MASTER LEASE." A true,
correct and complete copy of the Master Lease is attached hereto as Exhibit A
and incorporated by reference herein. Sublessor is currently the original tenant
under the Master Lease.

         B.       Sublessee wishes to sublease a portion of the Master Premises
consisting of approximately 4,450 square feet which portion is identified on
Exhibit B attached hereto and incorporated herein by this reference ("SUBLEASED
PREMISES"). Sublessor wishes to sublease the Subleased Premises to Sublessee on
the terms and conditions contained herein.

         Accordingly, in consideration of the mutual promises contained herein
and for other good and valuable consideration, receipt of which is hereby
acknowledged, the parties hereto agree as follows:

         1.       Subleased Premises: Sublessor hereby subleases to Sublessee,
and Sublessee hereby subleases from Sublessor the Subleased Premises on the
terms and conditions contained herein. All capitalized terms in this Sublease
shall have the meaning ascribed to them in the Master Lease unless otherwise
defined herein.

         2.       Term:

                  2.1      Term: The term (the "TERM") of this Sublease shall be
for a period commencing on January 26, 2003 if Sublessor has delivered
possession of the Subleased Premises to Sublessee on or before such date (the
"COMMENCEMENT DATE"). The Term shall end, without notice, on June 14, 2006 (the
"EXPIRATION DATE"), unless this Sublease is sooner


                                    -1 of 7-
<PAGE>

terminated pursuant to its terms or unless the Master Lease is sooner terminated
pursuant to its terms. If for any reason delivery of possession of the Subleased
Premises has not occurred on or before January 26, 2003, then this Sublease
shall automatically be void and of no force or effect. On any such termination,
neither Sublessor nor Sublessee shall have any rights against or obligations to
the other, provided that Sublessor shall return to Sublessee any monies
previously paid by Sublessee to Sublessor hereunder.

                  4.1      Incorporation of Master Lease: The terms, conditions

Section 4, or as otherwise set forth in this Sublease, or as otherwise
inconsistent with the terms or intent of this Sublease and except that: (a)
wherever in the Master Lease the word "Tenant" appears, for the purposes of this

<PAGE>

subject to the Master Lease, and that any termination of the Master Lease shall
likewise terminate this Sublease. In the event of any conflict between an
express term of this Sublease and an incorporated term, the express term shall
take precedence and govern.

                           Termination of Master Lease: If Master Lessor and
Sublessor jointly and voluntarily elect, for any reason whatsoever, to terminate
the Master Lease prior to the scheduled Master Lease termination date, then this

the monthly rental. In the event of the Master Lease termination, Sublessee
shall be compensated by Sublessor for the unused portion of prepaid rental.

                  4.2 Time Allowances; Consents: With respect to any obligation
of Sublessee to be performed under this Sublease, wherever the Master Lease
grants to Sublessor a specified number of days to perform its obligations under
the Master Lease, except as otherwise provided herein, Sublessee shall have the
same number of days to perform the obligation, including, without limitation,
curing any defaults.

                  4.3 Use: Sublessee may use the Subleased Premises only for
those uses permitted under the Master Lease, and in no event for any use
prohibited or restricted by the Master Lease or by law. Sublessee shall not
commit or permit to be committed on the Subleased Premises any act or omissions
which shall violate any term or condition of the Master Lease.

         5.       Right to Cure Defaults:

                  5.1      Sublessee's Rights: If Sublessor fails to perform any
act on its part to be performed by Sublessor hereunder, then Sublessee may, but
shall not be obligated to, after thirty (30) days after the date of Sublessee's
written notice to Sublessor identifying the failure, and after the passage of
any notice and cure periods, and subject to the terms of the Master Lease,
perform such act. All such sums paid, and all reasonable costs and expenses of
performing any such act, shall be payable promptly by Sublessor to Sublessee,
together with interest thereon at the Interest Rate from the date of the
expenditure until repaid.

         6.       Deposit: Sublessee shall pay Sublessor a security deposit in

the first month rent is due upon execution of this lease.

that they have dealt with no real estate brokers other than Vandermade. Each
party agrees to hold the other party harmless from and against all claims for
brokerage commissions, finder's fees or other compensation made by any other
agent, broker, salesman or finder as a consequence of said party's actions or
dealings with such agent, broker, salesman, or finder.

         8.       Authority to Execute: Sublessee and Sublessor each represent
and warrant to the other that each person executing this Sublease on behalf of
each party is duly authorized to execute and deliver this Sublease on behalf of
that party.

         9.       Commencement Date Violations: Notwithstanding anything
contained herein to the contrary, Sublessee shall have no duty, liability or
obligation whatsoever (financial


                                    -3 of 7-
<PAGE>

or otherwise) for or with respect to any violation, breach or non-compliance of
the Subleased Premises or Sublessor with respect to the Master Lease, any law,
regulation, ordinance, statute rule or other governmental order that existed on
the Commencement Date.

         10.      Intentionally Deleted

         11.      As-Is: Sublessor hereby represents and warrants that as of the
"Sublease Commencement Date" (i) to the best of Sublessor's knowledge, the roof
and building systems (for example, HVAC, mechanical, electrical, plumbing, water
and gas) are in good working order and repair, and (ii) to the best of
Sublessor's knowledge, the Subleased Premises are not in violation of any
ordinance, rule, code or regulation of any governmental agency and Sublessor has
not received any notice of a possible violation. Except for the foregoing
representations, warranties and covenants by Sublessor, Sublessee hereby
subleases the Subleased Premises "as is" and "where is" with no other
representation or warranty being made by Sublessor with respect to condition of
the Subleased Premises, nor any other promise by Sublessor to repair same.
Sublessor shall demise the space.

         12.      Sublease and Assignment: Pursuant to the restrictions of the
Master Lease, Sublessee may not sublease or assign all or any portion of this
Sublease. Any such Sublease or assignment shall be null, void and of no force or
effect. Sublessor and Sublessee acknowledge that this prohibition on subleasing
and assignment is required specifically by Master Lessor. Sublessor and
Sublessee recognize the difficulties that such a prohibition by Master Lessor
could cause if Sublessee desires to consolidate or merge. Therefore, if: there
shall occur (1) any assignment, merger or consolidation or other reorganization
of or affecting Sublessee and if Sublessee is not the surviving corporation; or
(2) any involuntary assignment or sublease by reason of corporate
reorganization, assignment, merger, consolidation, or for any other reason, then
unless Master Lessor's and Sublessor's advance written consents are obtained
(which consents may be withheld at their sole discretions), then this Sublease
shall terminate on the occurrence of any of the foregoing events.

         13.      Furniture: The Subleased Premises shall be delivered to
Sublessee with the assets listed on Exhibit C attached hereto which may be used
by Sublessee for no additional consideration throughout the Term. During the
Sublease Term, none of the assets listed on Exhibit C may be removed by
Sublessee from the Subleased Premises at any time and at the end of the term
said assets shall be delivered by Sublessee to Sublessor in the condition in
which they were delivered to Sublessee, reasonable wear and tear excepted.

         14.      Company Logo Sign. The Sublessee has the right to put signage
bearing the name and logo of the Sublessee at the roadside.

         15.      Surrender: Notwithstanding the incorporation of Section 8 of
the Master Lease, on expiration of the Term of this Sublease, or on any other
termination of this Sublease, Sublessee shall not be required to remove any
tenant improvements in or alterations to the Subleased Premises that were
installed in the Subleased Premises prior to the Commencement Date.

         16.      Termination Payment. If Master Lessor and Sublessor jointly
and voluntarily elect to terminate the Master Lease and this Sublease as
described in Section 4.2, above, then as of the termination, then Sublessor
shall pay to Sublessee a termination payment equal to the unused rental as of
the date of termination. If the Master Lease is terminated by reason of
Sublessor's breach thereof, and if such breach is in no way related to or
connected with a breach of this Sublease by Sublessee, and if after Master Lease
termination the Master Lessor requires Sublessee to continue its tenancy under
this Sublease at the Basic Rent paid by Sublessor under the Master Lease, then
Sublessor shall pay to Master Lessor on a monthly basis, as and when due, the
difference between the Basic Rent under the Master Lease and the Base Rent under
this Sublease for the remaining term of this Sublease (or if earlier, its
termination for any reason).
