                               SUBLEASE AGREEMENT

            THIS SUBLEASE AGREEMENT (this "Sublease") is entered into as of May
19, 2000, by and between DAMES & MOORE, INC., a Delaware corporation
("Sublessor"), and SOMERA COMMUNICATIONS, INC., a Delaware Corporation
("Subtenant").

                                    RECITALS

            A. Sublessor is the tenant under that certain Lease dated December
1, 1995, as amended by First Amendment to Lease dated January 30, 1996 and First
Amendment to Net, Net, Net Lease effective as of February 1, 1999, wherein Santa
Barbara Corporate Center, LLC, a California limited liability company
("Landlord") leased to Sublessor certain premises described as 5383 Hollister
Avenue in the unincopotared area of Santa Barbara County, California (the
"Master Premises") in the building known as GRCI Building (the "Building"). Said
Lease as amended prior to the date hereof is herein referred to as the "Master
Lease" and is attached hereto as Exhibit A and made a part hereof.

            B. Subtenant desires to sublease from Sublessor, and Sublessor is
willing to sublease to Subtenant, on the terms and conditions set forth herein,
including without limitation, Section 1 of this Sublease, all of the Master
Premises known herein as the "Sublease Premises" consisting of Suite 120,
containing approximately Eight Thousand Six Hundred Ninety-Six (8,696) rentable
square feet as delineated on the floor plan attached hereto as Exhibit B and
hereby made a part hereof; provided, however, upon the Commencement Date,
Sublessor shall deliver to Subtenant only that certain portion of the Premises
consisting of approximately Two Thousand One Hundred Thirty Two (2,132) rentable
square feet as delineated on the floor plan attached hereto as Exhibit D and
hereby made a part hereof (the "Partial Premises").

            NOW, THEREFORE, in consideration of the mutual covenants and
conditions herein contained, Sublessor and Subtenant (together, the "Parties"
and each sometimes a "Party") hereby agree and covenant with each other as
follows:

                  1. Demise of Sublease Premises.

                        (a) Sublessor shall sublease and demise to Subtenant,
and Subtenant shall hire and accept from Sublessor, the Sublease Premises on and
subject to the terms and conditions set forth in this Sublease; provided,
however, upon the Commencement Date, Sublessor shall deliver to Subtenant only
the Partial Premises and the remainder of the "Sublease Premises" ("Remainder
Premises") shall be delivered on or before October 1, 2000. The term "Sublease
Premises", as used in this Sublease, shall mean and refer only to the Partial
Premises until Sublessor delivers the Remainder Premises to Subtenant in which
case, upon such delivery of the Remainder Premises, Subtenant shall be obligated
to sublease all of the Sublease Premises and the term "Sublease Premises" shall
mean and refer to all of the Sublease Premises. Notwithstanding anything to the
contrary contained in this Section 1, if Sublessor does not so tender possession
to Subtenant of the Remainder Premises (without any tenant improvements being
made therto) by January 1, 2001 (The "Outside Date"), then as Subtenant's sole
and exclusive remedy against Sublessor for Sublessor's failure to deliver and/or
delay in the delivery of the Remainder Premises, Subtenant may terminate this
Sublease by delivering written notice therof to Sublessor at any time after the
Outside Date, but prior to Sublessor's tender of possession of the Remainder
Premises. If Subtenant fails to deliver such termination notice, or if Sublessor
tenders to Subtenant possession of the Sublease Premises (without any tenant
improvements being made thereto) at any time earlier than the expiration of ten
(10) business days following receipt of Subtenant's termination notice, then
upon the occurrence of any such events the foregoing right given to Subtenant to
terminate this Sublease as provided herein shall lapse and be null and void and
the Sublease shall remain in full force and effect with Subtenant having no
further right to terminate this Lease pursuant to the foregoing provision. If
Sublessor does so timely deliver to Subtenant possession of the Sublease
Premises (without any tenant improvements being made thereto), Subtenant shall
promptly deliver written
<PAGE>

notice to Sublessor confirming same (however, any failure by Subtenant to so
notify Sublessor shall not affect the enforceability of this Sublease).

                        (b) In consideration of the obligations contained in
this Sublease, Subtenant shall pay to Sublessor, upon the full possession of the
Sublease Premises (including the Remainder Premises), a moving reimbursement fee
in an amount equal to $50,000 or such lesser amount, if any, as Sublessor pays
to NanoMotion pursuant to a separate agreement between Sublessor and NanoMotion
("Moving Fee"); provided, however, that such Moving Fee shall not be owed to
Sublessor if possession of the Remainder Premises are tendered to Sublessee
after October 1, 2000. Furthermore, Sublessor shall have the right to increase
said amount to a total of $150,000 by requesting an additional amount up to
$100,000 within thirty (30) days after Sublessor's delivery of possession of the
Remainder Premises, which $100,000 shall be amortized over 36 months at a fixed
rate of interest equal to 8% per annum and credited back to Sublessee as a
partial rent credit spread evenly over the 36 month period commencing on the
first (1st) day of the calendar month following deliver of the $100,000. For
example, in the event Sublessor receives $100,000 from Subtenant, the monthly
credit due to Subtenant shall be $3,133.64 each month for a period of 36 months.
Subtenant shall pay such $100,000 to Sublessor within ten (10) days after
Sublessor's written request therefore. The payment by Subtenant of the Moving
Fee and $100,000 referred to above shall constitute "Rent" under this Sublease.

                  2. Term. The term of this Sublease shall commence upon
Sublease execution, or the date upon which Landlord consents to this Sublease
(if such consent is required under the Master Lease), whichever shall last occur
(the "Commencement Date"), and shall end on February 14, 2004 (the "Term")
unless sooner terminated, or extended, as provided herein. If Landlord's consent
to this Sublease is required under the Master Lease and (i) Landlord for any
reason disapproves this Sublease, this Sublease shall be of no further force and
effect; and (ii) if Landlord fails to give such consent by May 19, 2000, either
Party may then cancel this Sublease by giving written notice of cancellation to
the other Party before such consent is actually received. Neither Party shall
have liability to the other for any termination or cancellation under this
Section 2, unless such Party by its willful act caused Landlord to refuse timely
consent to this Sublease.

                  3. Rent and Security Deposit.

                        (a) Base Rent. Subtenant shall pay to Sublessor upon
execution of the Sublease the sum of Three Thousand One Hundred Fifty Three and
66/100 Dollars ($3,153.66) as rent ("Base Rent") for the first (1st) month of
the Term and Subtenant shall pay to Sublessor such Base Rent, each month, in
advance on the first (1st) day of each month of the Term without offset,
deduction or counterclaim; provided, upon Sublessor's tender of possession of
the Remainder Premises to Subtenant, Base Rent shall increase to and Subtenant
shall pay to Sublessor without offset, deduction or counterclaim, Twelve
Thousand Eight Hundred Sixty Three and 14/100 Dollars ($12,863.14) per month in
advance on the first (1st) day of each month of the Term after such tender of
possession of the Remainder Premises. Subtenant shall receive a credit (as set
forth in Section 1 (b) above) against monthly Base Rent in the event Subtenant
pays to Sublessor the $100,000 referenced in Section 1 (b) above. In the event
of a partial rent month, the Rent will be prorated on the basis of a thirty (30)
day month.

                        (b) Additional Rent. In addition to Base Rent, Subtenant
shall pay to Sublessor as Additional Rent ("Additional Rent") 100% (if all the
Sublease Premises is then subleased to Subtenant) or 24.5% (if only the Partial
Premises is then subleased to Subtenant) of all operating expenses, taxes and
assessments payable by Sublessor under the Lease ("Operating Expenses") and any
other charges assessed against the Sublease Premises under the Master Lease or
this Sublease. The Base Rent and Additional Rent may sometimes be referred to
herein collectively as the "Rent."

                        (c) Method of Payment. All Rent shall be paid to
Sublessor in lawful money of the United States, at the address specified for
notices in Section 22 below (or such other place as Sublessor may designate by
written notice to Subtenant from time to time), and shall be payable without
requirement of notice or demand thereof and without any rights of setoff or
deduction whatsoever.

                        (d) Escalation. Subtenant's base rent shall be adjusted
per paragraph 3.5 of the Master Lease.
<PAGE>

                        (e) Late Charges. The Parties agree that late payments
of Rent by Subtenant to Sublessor will cause Sublessor to incur costs not
contemplated by this Sublease, the amount of which is extremely difficult to
ascertain. Therefore the Parties agree that if any installment of Rent is not
received by Sublessor within five (5) days after due, Subtenant will pay to
Sublessor a late charge equal to five percent (5%) of the late payment. Interest
on any amounts payable by Subtenant under this Sublease shall accrue at the rate
of twelve percent (12%) per annum from the date delinquent until paid in full.

                        (f) Rent Defined. As used herein, the term "Rent" shall
mean Base Rent and the Additional Rent (including, without limitation,
Subtenant's share of the Operating Expenses).

                        (g) Free Rent; No Tenant Improvement Allowance. During
the first thirty (30) days following delivery by Sublessor of the (i) Partial
Premises, Base Rent applicable to the Partial Premises shall be forgiven and
(ii) Remainder Premises, Base Rent applicable to the Remainder Premises shall be
forgiven. Sublessor shall provide no tenant improvement allowance to Subtenant
under this Sublease.

                  4. Master Lease.

                        (a) Incorporation by Reference; Assumption. All of the
Articles of the Master Lease are incorporated into this Sublease as if fully set
forth in this Sublease, except the following: Basic Lease Provision 4,6,7 and 9,
and the following Master Lease Sections: 3.1, last sentence of Section 5.1, the
final two sentences of Section 17.17, Section 18, and Exhibits D and E. In
addition, Section 7.6, the second paragraph of Section 7.7 and Seciton 6.1 of
the Master Lease are incorporated into this Sublease except in no event or
circumstance shall Sublessor (i) be obligated to perform any of Landlord's
obligations under Sections 6.1 or 7.6 or (ii) indemnify Subtenant (as Landlord
indemnifies Sublessor, as "Lessee") under the second paragraph of Section 7.7 of
the Master Lease and Sublessor shall have no obligation or liability to
indemnify Subtenant except to the extent expressly set forth in this Sublease.
Section 17.29 of the Master Lease shall not be applicable unless and until
Subtenant ceases to be a publicly held company. Where applicable, references in
the Master Lease to Landlord will mean Sublessor and to Lessee will mean
Subtenant (for examply, Sublessor shall not be obligated to repair damage or
destruction of the Premises or Building under Section 8 of the Master Lease). If
any provisions of this Sublease conflict with any portion of the Master Lease as
incorporated herein, the terms of this Sublease will govern.

                        (b) Assumption of Lease Obligations. Subtenant will
assume and perform Sublessor's obligations as lessee under the Master Lease
during the Sublease Term to the extent such obligations are applicable to the
Sublease Premises. Subtenant will not commit or suffer any act or omission that
will violate any of the provisions of the Master Lease.

                        (c) No Assumption by Sublessor. Sublessor does not
assume any of the obligations of the Landlord under the Master Lease, including
without limitation, the requirement to carry insurance under Section 7.6 of the
Master Lease or to perform Landlord's maintenance, repair and alteration
obligations under Section 6.1 of the Master Lease. Subtenant acknowledges that
Sublessor's obligation to perform services, provide utilities, make repairs and
carry insurance shall be satisfied only to the extent that the Landlord under
the Master Lease satisfies those same obligations. With respect to the
performance by Landlord of its obligations under the Master Lease, Sublessor's
sole obligation with respect thereto will be to request the same, on request in
writing by Subtenant, and to use reasonable efforts to obtain the same from
Landlord; provided, however, Sublessor will have no obligation to institute
legal action against Landlord.

                        (d) Performance Directly to Landlord. At any time and on
reasonable prior notice to Subtenant, Sublessor can elect to require Subtenant
to perform its obligations under this Sublease directly to Landlord, in which
event Subtenant will send to Sublessor from time to time copies of all notices
and other communications it will send to and receive from Landlord.

                        (e) Landlord Defaults; Consents. Notwithstanding any
provision of this Sublease to the contrary, (a) Sublessor will not be liable or
responsible in any way for any loss, damage, cost, expense, obligation or
liability suffered by Subtenant by reason of or as the result of any breach,
default or failure to perform by
<PAGE>

the Landlord under the Master Lease, and (b) whenever the consent or approval of
Sublessor and Landlord is required for a particular act, event or transaction
(i) any such consent or approval by Sublessor will be subject to the consent or
approval of Landlord, and (ii) should Landlord refuse to grant such consent or
approval, under all circumstances, Sublessor will be released from any
obligation to grant its consent or approval.

                        (f) Termination of Master Lease. If the Master Lease is
terminated for any reason whatsoever, this Sublease will terminate
simultaneously and any unearned Rent paid in advance by Subtenant shall be
refunded to Subtenant.

                  5. Maintenance and Repairs. At all times during the Sublease
Term, Subtenant, at its sole cost, will maintain the Sublease Premises and every
part thereof and all equipment, fixtures and improvements therein in good
condition and repair in accordance with the terms of the Master Lease. At the
end of the Sublease Term, Subtenant will surrender the Sublease Premises in as
good condition as when received, reasonable wear and tear excepted. Subtenant
will be responsible for all repairs required to be performed by the Lessee under
the Master Lease.

                  6. Use. Subtenant shall use the Sublease Premises solely for
general office use in keeping with the character of a first class office
building and shall not use or permit the use of the Sublease Premises in any
manner which will tend to create waste or a nuisance, or shall tend to disturb
Sublessor or other tenants of the Building.

                  7. Parking. Subtenant shall be entitled to that portion of
Sublessor's parking allotment under the Master Lease which is allocable to the
Sublease Premises.

Environmental Laws, including, without limitation, any notice required by

investigation or any governmental or regulatory action, proceeding, order or
decree relating to any Subtenant Related Environmental Problem and, at
Subtenant's expense, shall comply in all respects with any such order or decree
within the time period allowed thereby for compliance, unless Sublessor notifies
Subtenant that Sublessor intends to contest such order or decree. Prior to
commencing any corrective or remedial action with respect to any Environmental
Problem (except for any such action taken to comply with an order or decree
which Sublessor has not elected to contest), Subtenant shall obtain the consent
of Sublessor (which shall not be unreasonably withheld or delayed) and all
governmental entities having jurisdiction thereof. Subtenant shall not be
responsible or liable to Sublessor for any costs incurred due to any Hazardous
Material which was present on the Sublease Premises prior to Subtenant's
occupancy thereof.

                        (e) Indemnity. Subtenant shall indemnify, defend and
hold harmless Sublessor (through counsel reasonably satisfactory to Sublessor)
against any and all claims, demands, actions, proceedings, liabilities, punitive

of any of the provisions of this Section 8; or (iii) any Subtenant Related
Environmental Problem. Without limiting the generality of the foregoing,

consulting, legal, response, remedial, monitoring or clean up costs incurred by
Sublessor (whether or not in response to any governmental or judicial action,
decree or order) relating to any Environmental Default; and (II) any
investigative, consulting or legal costs incurred by Sublessor in defending
against any regulatory or judicial order or decree, or satisfying any judgment
or the terms of any settlement or consent decree, relating to any Environmental
Default. Subtenant's indemnity obligations under this Section 8 shall survive
the expiration or earlier termination of this Sublease.

                        (f) Sublessor hereby represents and warrants to
Subtenant that (i), to Sublessor's actual knowledge (without duty of inquiry or
investigation), from the date of Sublessor's initial occupancy of the Sublease
Premises to the date of this Sublease, Sublessor has not caused any
Environmental Problem and (ii) during Sublessor's occupancy of the Sublease
Premises, Sublessor used the Sublease Premises for general office uses and did

                        (1) Alterations and Improvements by Subtenant. Subtenant
will not make any alterations, additions or improvements to the Sublease
Premises ("Alterations") without obtaining the prior written
<PAGE>

consent of Sublessor thereto, which consent shall be deemed granted if Subtenant
obtains Landlord's consent thereto and notifies Sublessor in writing thereof at
least ten (10) days prior to commencement of such Alterations; provided,
however, Subtenant shall indemnify, defend (by counsel reasonably acceptable to
Sublessor) and hold Sublessor harmless from and against all claims, damages,
losses, liabilities, judgments, costs and expenses suffered or incurred by
Sublessor arising from or related to Subtenants' failure to (i) surrender the
Sublease Premises in the condition in which Sublessor must surrender the
Sublease Premises to Landlord pursuant to the Master Lease, and (ii) remove any
Alterations made by Subtenant to the extent required by Landlord and (iii)
restore the Subleased Premises to the condition required by t the terms of the
Master Lease. The term "Alterations" includes any alterations, additions or
improvements made by Subtenant to comply with the ADA as required in Section 11
below. All Alterations must be constructed (i) in a good and workmanlike manner
using materials of a quality comparable to those on the Sublease Premises, (ii)
in conformance with all relevant codes, regulations and ordinances and (iii)
only after necessary permits, licenses and approvals have been obtained by
Subtenant from the appropriate governmental agencies. All Alterations will be
made at Subtenant's sole cost and diligently prosecuted to completion. Any
contractor or other person making any Alterations must first be reasonably
approved in writing by Sublessor; provided, however, Sublessor hereby approves
of Trabucco Construction, Inc. as a contractor.

                        (2) Disposition on Termination. Upon the expiration of
the Sublease Term or earlier termination of this Sublease, Sublessor may elect
to have Subtenant either (i) surrender with the Sublease Premises any or all of
the Alterations as Sublessor may determine (except personal property as provided
in Section 10 below), which Alterations will become the property of Sublessor,
or (ii) promptly remove any or all of the Alterations designated by Sublessor to
be removed, in which case Subtenant must, at Subtenant's sole cost, repair and
restore the Sublease Premises to its condition as of the Commencement Date,
reasonable wear and tear excepted.

                  10. Removal of Personal Property. All articles of personal
property, and all business and trade fixtures, machinery and equipment, cabinet
work, furniture and movable partitions, if any, owned or installed by Subtenant
at its expense in the Sublease Premises will be and remain the property of
Subtenant and may be removed by Subtenant at any time, provided that Subtenant,
at its expense, must repair any damage to the Sublease Premises caused by such
removal or by the original installation. In the event Master Lessor so requires,
Sublessor shall require that Subtenant remove all or any part of Subtenant's
personal property at the expiration of the Sublease Term or sooner termination
of this Sublease, in which event the removal will be done at Subtenant's expense
and Subtenant, prior to the end of the Sublease Term or upon sooner termination
of this Sublease, will repair any damage to the Sublease Premises caused by its
removal.

                  11. Condition of Premises. Subtenant agrees to accept the
Sublease Premises in an "AS IS" and "WITH ALL FAULTS" condition. Without
limiting the foregoing, Subtenant's rights in the Sublease Premises are subject
to all local, state and federal laws, regulations and ordinances governing and
regulating the use and occupancy of the Sublease Premises and subject to all
matters now or hereafter of record. Subtenant acknowledges that neither
Sublessor nor Sublessor's agent has made any representation or warranty as to:

                        (1)   the present or future suitability of the Sublease
                              Premises for the conduct of Subtenant's business;

                        (2)   the physical condition of the Sublease Premises;

                        (3)   the expenses of operation of the Sublease
                              Premises;

                              the use of Subtenant or any other person,
                              including Subtenant's employees, agents, invitees
                              or customers;

                        (5)   the compliance of the Sublease Premises with any
                              applicable laws, regulations or ordinances; or

                        (6)   any other matter or thing affecting or related to
                              the Sublease Premises.
<PAGE>

                              Subtenant acknowledges that no rights, easements
                              or licenses are acquired by Subtenant by
                              implication or otherwise except as expressly set
                              forth herein. Subtenant will, prior to acceptance
                              of delivery of possession of the Sublease
                              Premises, inspect the Sublease Premises and become
                              thoroughly acquainted with its condition.
                              Subtenant acknowledges that the taking of
                              possession of the (i) Partial Premises by
                              Subtenant will be conclusive evidence that the
                              Partial Premises were in good and satisfactory
                              condition at the time such possession was taken
                              and (ii) Remainder Premises by Subtenant, as and
                              when possession is taken, will be conclusive
                              evidence that the Remainder Premises were in good
                              and satisfactory condition at the time such
                              possession is taken. Subtenant specifically agrees
                              that, except as specifically provided by laws in
                              force as of the date hereof, Sublessor has no duty
                              to make any disclosures concerning the condition
                              of the Building and the Sublease Premises or the
                              appropriateness of the Sublease Premises for
                              Subtenant's intended use and Subtenant expressly
                              waives any duty which Sublessor might have to make
                              any such disclosures. Subtenant further agrees
                              that, in the event Subtenant subleases all or any
                              portion of the Sublease Premises, Subtenant will
                              indemnify and defend Sublessor for, from and
                              against any matters which arise as a result of
                              Subtenant's failure to disclose any relevant
                              information about the Building or the Sublease
                              Premises to any employee, agent, subtenant or
                              assignee. Subtenant will comply will all laws and
                              regulations relating to the use or occupancy of
                              the Sublease Premises, including without
                              limitation, making structural alterations or
                              providing auxiliary aids and services to the
                              Sublease Premises as required by the Americans
                              with Disabilities Act of 1990, 42 U.S.C. ss. 12101
                              et seq. (the "ADA").

            12.               Insurance.

                  (a) Coverage. At all times during the Sublease Term, Subtenant
will, at its sole cost, procure and maintain the types and amounts of insurance
coverage as is required of Sublessor in the Master Lease.

                  (b) Policies. All insurance required to be carried by
Subtenant must be in a form satisfactory to Landlord and Sublessor and carried
with companies reasonably acceptable to Sublessor and Landlord. Subtenant must
provide Sublessor with an original certificate of insurance showing Sublessor
and Landlord as additional insureds on all policies of insurance excluding the
insurance required under Section 12(a)(5). Subtenant's policies of insurance
shall provide that they are primary coverage for all matters insured therein.
The certificate must provide for a thirty (30) day written notice to Sublessor
in the event of cancellation or material change in coverage.

                  (c) Subrogation. Sublessor and Subtenant will each obtain from
their respective insurers under all policies of fire, theft, public liability
and other insurance maintained by either of them at any time during the Sublease
Term insuring or covering the Sublease Premises excluding the insurance required
under Section 12(a)(5), a waiver of all rights of subrogation which the insurer
of one party might otherwise have, if at all, against the other party and each
party waives any and all rights of recovery against the other and their
respective officers, employees and agents for loss of or any damage to such
waiving party or its property to the extent such loss or damage is insured
against under any insurance policy in effect at the time of such loss or damage.

            13. No Encumbrance. Subtenant will not voluntarily, involuntarily or
by operation of law mortgage or otherwise encumber all or any part of
Subtenant's interest in the Sublease or the Sublease Premises.

            14. Default. The occurrence of any of the following shall constitute
a default (an "Event of Default") by Subtenant:

                  (a) Failure to pay Rent when due, if such failure continues
for five (5) days after notice has been given to Subtenant; provided that if
Subtenant fails to pay Rent when due more than three (3) times during a
consecutive twelve (12) month period during the Sublease Term, Sublessor's
obligation to notify Subtenant of any such
<PAGE>

failure will end after the third such occurrence, and a noncurable Event of
Default shall occur if Subtenant fails to pay any Rent due thereafter when such
Rent is due; or

                  (b) Failure to pay any other sum or charge payable by
Subtenant hereunder as and when the same becomes due and payable, and such
failure continues for more than ten (10) days after Sublessor gives written
notice thereof to Subtenant; provided that if Subtenant fails to pay any sum or
charge when due more than three (3) times during a consecutive twelve (12) month
period during the Sublease Term, Sublessor's obligation to notify Subtenant of
any such failure will end after the third such occurrence, and a noncurable
Event of Default shall occur if Subtenant fails to pay any sum or charge due
thereafter when such sum or charge is due; or

                  (c) Subtenant abandons or vacates the Sublease Premises; or

                  (d) Failure to perform or observe any other agreement,
covenant, condition or provision of this Sublease to be performed or observed by
Subtenant as and when performance or observance is due, and such failure
continues for more than twenty five (25) days after Sublessor gives written
notice thereof to Subtenant, or if the default cannot be cured within said
twenty five (25) day period and Subtenant fails within said period to commence
with due diligence and dispatch the curing of such default or, having so
commenced, thereafter fails to prosecute or complete with due diligence and
dispatch the curing of such default; or

                  (e) Any act or omission on the part of Subtenant which is the
basis of a claim by Landlord of a default on the part of Tenant under the Master
Lease (whether or not Landlord gives Sublessor written notice of default under
the Master Lease) unless Subtenant cures such act or omission to Landlord's
satisfaction within three (3) days after either Landlord or Sublessor give
Subtenant notice of such act or omission; or

                  (f) The filing of a petition by or against Subtenant under the
Federal Bankruptcy Code or any state bankruptcy or insolvency law (unless, in
the case of a petition filed against Subtenant, Subtenant contests such petition
and obtains a dismissal thereof within sixty (60) days after filing);
Subtenant's making any general assignment for the benefit of its creditors; the
appointment of a trustee or receiver to take possession of all or any portion of
Subtenant's assets located at the Sublease Premises or of Subtenant's interest
under this Sublease (unless Subtenant contests such appointment and obtains
repossession of such assets or interest within sixty (60) days); the attachment,
execution or other judicial seizure of all or any portion of Subtenant's assets
located at the Sublease Premises or of Subtenant's interest under this Sublease;
or Subtenant's acknowledgment in writing that it is insolvent or generally
unable to pay its obligations as they fall due.

            15. Remedies for Subtenant Default. Upon and after the occurrence of
any Event of Default (and until cure of such default has been tendered by
Subtenant and accepted by Sublessor), Sublessor shall have the following rights
and remedies:

                  (a) The right to terminate this Sublease and the interest and
estate granted in the Sublease Premises hereby, by giving Tenant written notice
of such termination (which shall be effective upon the later of the receipt of
such notice or the date and time of termination specified therein).

                  (b) In the event Sublessor elects to terminate this Sublease,
the right to recover from Subtenant:

                        (1) The worth at the time of award of the unpaid rent
earned at the date of such termination,

                        (2) The worth at the time of award of the amount by
which the unpaid Rent which would have earned after the date of such termination
until the time of award exceeds the amount of such rental loss that Subtenant
proves could have been reasonably avoided,
<PAGE>

                        (3) The worth at the time of award of the amount by
which the unpaid Rent which would have been earned for the balance of the
Sublease Term after the time of award exceeds the amount of such rental loss
that Subtenant proves could have been reasonably avoided, and

                        (4) Any other amount necessary to compensate Sublessor
for all of the detriment proximately caused by Subtenant's failure to observe or
perform any of its obligations under this Sublease or which in the ordinary
course of events would be likely to result therefrom, including, without
limitation, expenses incurred in re-entering and taking possession of the
Sublease Premises, costs incurred in cleaning and refitting the Sublease
Premises for a new tenant and costs (including reasonable broker's commissions)
incurred in reletting the Sublease Premises.

The "worth at the time of award" shall be computed, for purposes of clauses (1)
and (2) above, by allowing interest at two percent over the prime or corporate
reference rate announced from time to time by Bank of America, or, if lower, the
maximum rate permitted by law during the period in question, and, for purposes
of clause (3) above, by discounting such amount at the discount rate of the
Federal Reserve Bank in the State in which the Sublease Premises are located in
effect at the time of the award, plus one percent (1%).

                        (c) The right to re-enter and repossess the Sublease
Premises, and remove all persons and property therefrom, by any suitable action
or proceeding without liability to Subtenant or anybody claiming by, through or
under Subtenant. No such re-entry or repossession shall be deemed an election to
terminate this lease, unless Sublessor has given Subtenant written notice of
termination pursuant to subparagraph (a) above or such termination is otherwise
decreed by a court of competent jurisdiction. Sublessor may store any property
removed from the Sublease Premises at Subtenant's expense and, if Subtenant does
not pay the cost of such removal and storage within the later of ten (10) days
after written demand to Subtenant therefor or thirty (30) days after the removal
and storage of such property, Sublessor may sell such property and apply the
proceeds of such sale to the cost of such removal and storage and to any other
amounts then owed Sublessor hereunder.

                        (d) Sublessor has the remedy described in California
Civil Code Section 1951.4 (Sublessor may continue Sublease in effect after
Subtenant's breach and abandonment and recover Rent as it becomes due, if
Subtenant has right to sublet or assign, subject only to reasonable
limitations).

                        (e) Without terminating this Sublease, Sublessor shall
have the right to relet the Sublease Premises or any part thereof, for
Subtenant's account, but on such terms and conditions and at such rentals as
Sublessor in its sole discretion deems advisable, with the right at Subtenant's
expense to make such alterations and repairs in the Sublease Premises and to
incur such other expenses as Sublessor in its discretion deems necessary for
such reletting. Rents and other sums received by Sublessor from any such
reletting shall be applied: first, to the payment of expenses incurred by
Sublessor in reletting and repossessing the Sublease Premises and in the
reletting thereof; second, to sums other than Rent then owed by Subtenant to
Sublessor hereunder; third, to installments of Rent then owed Sublessor
hereunder; fourth, to future installments of Rent, as they become due; and,
fifth, any balance to Subtenant. If the rents and other revenues received by
Sublessor from any such reletting are insufficient to pay in full the amounts
due Sublessor hereunder (including, without limitation, reimbursement of the
expenses of reentering, repossessing and reletting the Sublease Premises),
Subtenant shall, upon demand and from time to time, pay the deficiency to
Sublessor.

                        (f) Without terminating this Sublease, seek and obtain
the appointment of a receiver to take possession of the Sublease Premises, relet
the same, collect and receive any Rents and other amounts payable to Subtenant
with respect to the Sublease Premises and apply such receipts, first, to the
expenses of such receivership and, then, in accordance with subparagraph (e)
above.

                        (g) To cure any default on the part of Subtenant and to
recover from Subtenant the cost of such cure, upon demand, together with
interest thereon from the date paid at an annual rate of ten percent (10%).
Sublessor's cure of any default hereunder shall not be deemed to waive such
default or any other Event of Default.

                        (h) Any other right or remedy provided by law or in
equity or in the Master Lease.
<PAGE>

The rights and remedies of Sublessor provided in this Sublease are, to the
maximum extent permitted by law, cumulative and not mutually exclusive.

            16. Indemnification and Limitation on Liability. The terms of
subsections 16(a), (b) and (c) below shall not be effective unless and until
Sublessor tenders possession of the Remainder Premises to Subtenant and Section
16(f) shall be in full force and effect until Sublessor tenders possession of
the Remainder Premises to Subtenant. Upon such tender of possession of the
Remainder Premises to Subtenant, subsections 16(a), (b) and (c) shall be in full
force and effect and fully enforceable, and the terms of Section 16(f) below
shall be of no further force or effect and shall be deemed deleted from this
Sublease.

                  (a) Subtenant hereby agrees to indemnify Sublessor and
Sublessor's directors, officers, shareholders, partners, members, principals,
employees, agents, servants, contractors, subcontractors, visitors, licensees,
successors and assigns (collectively, "Sublessor's Representatives") against and
save Sublessor and Sublessor's Representatives harmless from any and all losses,
costs, damages, charges, liabilities, obligations, fines, penalties, claims,
demands, or judgments and any and all expenses, including, without limitation,
reasonable attorneys' fees and expenses, court costs, and costs of appeal,
settlement and negotiations (collectively, "Claims"), arising out of or in
connection with: (a) Subtenant's use of the Sublease Premises; (b) the conduct
of Subtenant's business or any activity, work or thing done, permitted or
suffered by Subtenant in, on or about the Sublease Premises or the Building; (c)
any failure to perform or observe any of the terms, covenants, conditions or
provisions required to be performed or observed by Subtenant under this Sublease
or the Master Lease; or (d) any negligence or other misconduct of Subtenant or
any of Subtenant's Representatives in connection with the performance of
Subtenant's obligations under this Sublease; or (e) any mechanic's lien and
other liens and encumbrances filed by any person claiming by, through or under
Subtenant, including security interests in any materials, fixtures, equipment
and any other improvements or appurtenances installed in, located on or
constituting part of the Sublease Premises. In the event that any action or
proceeding is brought against Sublessor by reason of any of clauses (a) through
(e) inclusive of this Section 16, Subtenant shall, at the request of Sublessor,
assume the defense of the same at Subtenant's sole cost with counsel reasonably
satisfactory to Sublessor. Sublessor and its insurers shall each have the right
to employ, at its expense, separate counsel in any such action or proceeding and
to participate in the defense thereof. Subtenant shall consent to and indemnify
Sublessor against the costs of any reasonable settlement agreed to by Sublessor
of such action or proceeding.

                  (b) Subtenant hereby assumes all risk of damage to property or
injury to persons in or on the Sublease Premises or arising from the use or
occupation thereof from any cause whatsoever, except when caused by the gross
negligence or willful misconduct of Sublessor.

                  (c) Sublessor shall not be responsible or liable to Subtenant
or to those claiming by, through or under Subtenant for any injury, loss or
damage that may be occasioned by or through the acts or omissions of: (i)
persons occupying other premises in the Building, or (ii) Sublessor or
Sublessor's Representatives unless proximately caused by (A) the gross
negligence or willful misconduct of Sublessor or Sublessor's Representatives or
(B) the negligence of Sublessor or Sublessor's Representatives if such
negligence is covered by and compensable under insurance obtained by Sublessor.
Sublessor shall not be responsible or liable to Subtenant for any defect or
failure, in (or any act or omission in the construction of) the Building, the
Sublease Premises or any Building system, nor shall it be responsible or liable
for any injury, loss or damage to any person or property of Subtenant or
Subtenant's Representatives or any other person caused by or resulting from
fire, electricity, gas, water, or other utility (or interruption therein) or
from rain, snow, ice, theft, bursting, breakage, explosion, implosion, leakage,
steam, running, backing up, seepage, or the overflow of water or sewerage in any
part of the Building or for any injury, loss or damage caused by or resulting
from acts of God or the elements. Subtenant shall give prompt notice to
Sublessor in case of fire, casualty, defect or accident in the Sublease Premises
or in the Building or of defects therein or in any Building systems.

                  (d) Subtenant's indemnity obligations under this Section 16
shall survive the expiration or earlier termination of this Sublease.

                  (e) Subtenant hereby expressly assumes any and all indemnity
obligations of Sublessor under the Master Lease that relate to the Partial
Premises arising and accruing on or after the date of the Sublease and (ii)
Remainder Premises arising and accruing on or after the date Subtenant takes
possession of the Remainder Premises.
<PAGE>

                  (f) Until Sublessor delivers the Remainder Premises to
Subtenant, (i) Subtenant shall indemnify, defend and hold harmless Sublessor to
the same extent as Sublessor, as Lessee under the Master Lease (under the terms
of Section 7.7 of the Master Lease), has agreed to indemnify, defend and hold
harmless Landlord, as Lessor, under the Master Lease, (ii) Sublessor shall be
exempt from liability, and shall neither be liable for injury to Sublessee's
business or any loss of income therefrom or for damage to the property of the
Subtenant nor liable for injury to the person of Subtenant, to the same extent
as Landlord, under Section 7.8 of the Master Lease, is exempt from liability and
not liable to Sublessor, as Lessee under the Master Lease and (iii) Sublessor
shall indemnify, defend and hold Subtenant harmless from and against any and all
Claims caused by the negligent acts, negligent omissions or willful misconduct
of Sublessor, except to the extent caused by Subtenant. This subsection 16(f)
shall be applicable and in full force and effect until Sublessor tenders
possession of the Remainder Premises to Subtenant and, upon Sublessor's tender
of possession of the Remainder Premises to Subtenant, this subsection 16(f)
shall be of no further force or effect and shall be deemed deleted from this
Sublease.

            17. Assignment and Subletting. Subtenant shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet or otherwise transfer or
encumber all or any part of Subtenant's interest in this Sublease or in the
Sublease Premises, without Sublessor's prior written consent which shall not be
unreasonably withheld and the prior written consent of the Landlord, as provided
in the Master Lease.

            18. Signs. Subtenant shall not place any sign upon the Sublease
Premises without Sublessor's prior written consent; provided, however, that
Sublessor shall not unreasonably withhold its consent to any sign approved by
Landlord; provided, further, that Subtenant shall have the right to place
identification signs on doors leading from the common corridor into the Sublease
Premises with Landlord's approval, but Subtenant shall repair, or reimburse
Sublessor on demand for the cost of repairing, any damage to such doors
resulting from the installation or removal of such signage. Subtenant shall be
solely responsible for negotiating with the Landlord appropriate informational
lines on the Building directory.

            19. Brokers. Each of Sublessor and Subtenant represents to the other
Party that it has not employed or consulted with any broker other than Blair
Hayes Commercial and Pacifica Commercial Realty (collectively, "Brokers") with
respect to this Sublease. Each Party shall indemnify and hold the other harmless
from and against all Claims incurred or resulting from the claim of any person,
except Brokers, that a commission or fee is due in connection with this Sublease
if such claim is based upon any statement or agreement alleged to have been made
by such Party. Payment of Brokers is Sublessor's responsibility. Sublessor shall
pay to Blair Hayes Hayes Commercial and Pacifica Commercial Realty a commission
equal to two percent (2%) each of the total Base Rent for the Partial Premises
and, in the event the Remainder Premises is delivered to Subtenant, for the
Remainder Premises in addition to the Partial Premises. The commission
applicable to the (i) Partial Premises shall be paid 1/2 upon submittal of a
fully executed approved Sublease Agreement and 1/2 upon Subtenant's occupancy of
the Partial Premises for purposes of conducting its business and (ii) Remainder
Premises shall be paid upon Subtenant's occupancy of the Remainder Premises for
purposes of conducting its business.

            20. Holding Over. If Subtenant holds over after the expiration of
the Sublease Term or earlier termination of this Sublease, with or without the
express or implied consent of Sublessor, then at the option of Sublessor,
Subtenant will become and be only a month-to-month tenant at a rent equal to one
hundred twenty five percent (125%) of the rent payable by Subtenant immediately
prior to such expiration or termination, and otherwise upon the terms, covenants
and conditions herein specified. Notwithstanding any provision to the contrary
contained herein, (i) Sublessor expressly reserves the right to require
Subtenant to surrender possession of the Sublease Premises upon the expiration
of the Sublease Term or upon the earlier termination of this Sublease and the
right to assert any remedy at law or in equity to evict Subtenant and/or collect
damages in connection with any holding over, and (ii) Subtenant will indemnify,
defend and hold Sublessor harmless from and against any and all liabilities,
claims, demands, actions, losses, damages, obligations, costs and expenses,
including, without limitation, attorneys' fees incurred or suffered by Sublessor
by reason of Subtenant's failure to surrender the Sublease Premises on the
expiration of the Sublease Term or earlier termination of this Sublease.
<PAGE>

            21. Subordination. This Sublease is subject and subordinate to the
Master Lease, to all ground and underlying leases, and to all mortgages and
deeds of trust which may now or hereafter affect such leases, the leasehold
estate or estates thereby created or the real property of which the Sublease
Premises form a part, and to any and all renewals, modifications,
consolidations, replacements and extensions thereof.

shall be in writing and delivered to the applicable party personally, or by
United States Postal Service, first class registered or certified mail, postage
prepaid, return receipt requested, in either case to the address indicated for
such party below; and shall be deemed given, delivered and received only upon
such personal delivery or at the time of delivery or attempted delivery shown

            23. Waivers. The failure or delay of either Party to insist in any
instance upon the strict performance or observance of any obligation or
condition on the part of the other under this Sublease, or to exercise any right
or remedy provided herein, shall not be deemed a waiver of such obligation,
condition, right or remedy, except where this Sublease provides expressly that a
right or remedy must be exercised within a specific time and such time has
elapsed. No waiver by either Party of any right or obligation contained in this
Sublease shall be deemed to have been made, unless made expressly in writing by
the Party entitled to the performance of the obligation, satisfaction of the
condition or exercise of the right in question. Sublessor's acceptance of any
partial payment of Rent due Sublessor hereunder shall not satisfy or discharge
Subtenant's obligation to pay the balance of Rent then due, nor shall
Sublessor's acceptance of any payment of Rent when Subtenant is in breach of any
other obligation or condition under this Sublease be deemed a waiver of such
breach.

            24. Estoppel Certificates.

                              (1) Obligation to Provide. Subtenant will at any
      time upon not less than ten (10) days' prior written notice from Sublessor
      execute, acknowledge and deliver to Sublessor a statement in writing (i)
      certifying that this Sublease is unmodified and in full force and effect
      (or, if modified, stating the nature of such modification and certifying
      that this Sublease, as so modified, is in full force and effect), the
      amount of any security deposit, and the date to which the Rent and other
      charges are paid in advance, if any, and (ii) acknowledging that there are
      not, to Subtenant's knowledge, any uncured defaults on the part of
      Sublessor hereunder or of Landlord under the Master Lease, or specifying
      such defaults if any are claimed. Any such statement may be conclusively
      relied upon by any prospective purchaser or encumbrancer to the Sublease
      Premises.

                              (2) Failure to Provide. At Sublessor's option,
      Subtenant's failure to deliver a statement within the time required by
      Section 24(a) above, will be conclusive upon Subtenant (i) that this
      Sublease is in full force and effect, without modification except as may
      be represented by Sublessor, (ii) that there are no uncured defaults in
      Sublessor's performance hereunder or in Landlord's performance under the
      Master Lease, and

      (iii) that not more than one month's Rent has been paid in advance, or
      such failure may be considered by Sublessor as a material default by
      Subtenant under this Sublease.

            25. Computation of Time. The term "day" means a calendar day, and
the term "business day" means any day other than a Saturday, Sunday or a bank
holiday under the laws of the United States or the State of California. Any
period of time specified in this Sublease which would otherwise end upon a
non-business day shall be extended to, and shall end upon, the next following
business day.

            26. Quiet Enjoyment. Subtenant, upon paying the Rent and performing
each of its obligations under this Sublease, shall lawfully and quietly hold,
occupy and enjoy the Sublease Premises, as is relevant, during the Term of this
Sublease without hindrance or molestation of anyone lawfully claiming by,
through or under Sublessor, subject, however, to the provisions set forth in
this Sublease. Sublessor will have the right to enter the Sublease Premises at
any time, in the case of an emergency, and otherwise at reasonable times, for
the purpose of inspecting the condition of the Sublease Premises and for
verifying compliance by Subtenant with this Sublease and the Master Lease and
permitting Sublessor to perform its obligations under this Sublease and the
Master Lease.

            27. Entire Agreement; Modification; Binding Effect. This Sublease
constitutes the entire agreement between the Parties pertaining to the subject
matter hereof and supersedes all prior agreements, understandings and
representations of the Parties with respect to the subject matter hereof. This
Sublease may not be modified, amended, supplemented or otherwise changed, except
by a writing executed by both Parties. Except as otherwise expressly provided
herein, this Sublease shall bind and inure to the benefit of the Parties and
their respective successors and assigns.

            28. Attorneys' Fees. Should either Party institute any action or
proceeding against the other for any reason or to enforce any provision of this
Sublease or for damages by reason of an alleged breach of any provision hereof,
the prevailing Party shall be entitled to receive all costs and expenses
(including reasonable attorneys' fees) incurred by such prevailing Party in
connection with such action or proceeding.

            29. Execution in Counterparts. This Sublease may be executed in two
counterparts, and by each Party on a separate counterpart, each of which when so
executed and delivered shall be deemed an original, and both of which when taken
together shall constitute but one and the same instrument.

            30. Governing Law. This Sublease shall be governed by and
interpreted in accordance with the laws of the State of California.

            31. WAIVER OF JURY TRIAL. SUBLESSOR AND SUBTENANT, TO THE EXTENT
THEY MAY LEGALLY DO SO, HEREBY EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY OF ANY
CLAIM, DEMAND, ACTION, CAUSE OF ACTION, OR PROCEEDING ARISING UNDER OR WITH
RESPECT TO THIS SUBLEASE, OR IN ANY WAY CONNECTED WITH, OR RELATED TO, OR
INCIDENTAL TO, THE DEALINGS OF THE PARTIES HERETO WITH RESPECT TO THIS SUBLEASE
OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING
OR HEREAFTER ARISING, AND IRRESPECTIVE OF WHETHER SOUNDING IN CONTRACT, TORT OR
OTHERWISE. TO THEY EXTENT THEY MAY LEGALLY DO SO, SUBLESSOR AND SUBTENANT AGREE
THAT ANY SUCH CLAIM, DEMAND, ACTION, CAUSE OF ACTION, OR PROCEEDING SHALL BE
DECIDED BY A COURT TRIAL WITHOUT A JURY AND THAT ANY PARTY HERETO MAY FILE AN
ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE OTHER PARTY OR PARTIES HERETO TO WAIVER OF ITS OR
THEIR RIGHT TO TRIAL BY JURY. THE PARTIES HAVE SET FORTH THEIR INITIALS BELOW TO
INDICATE THEIR AGREEMENT WITH THE JURY TRIAL WAIVER PROVISION CONTAINED IN THIS
SECTION.
