                                       the second floor of the Building which
                                       space has already been demised as shown
                                       on Exhibit "B". The Leased Premises
                                       consists of approximately 52,905 rentable
                                       square feet and, for purposes of this
                                       Lease, is agreed to contain said number
                                       of rentable square feet.

        Parking Spaces:                A number of spaces equal to 3.2
                                       multiplied by the rentable square footage
                                       of the Leased Premise from time to time,
                                       and divided by 1,000, to be available on
                                       an undesignated and unreserved basis.

        Tenant's Expense Share:        The term "Tenant's Expense Share" shall
                                       mean the percentage obtained by dividing
                                       the rentable square footage of the Leased
                                       Premises at the time of calculation by
                                       the rentable square footage of all
                                       buildings located on the Property at the
                                       time of calculation. Such percentage is
                                       currently 56.44%. In the event that the
                                       rentable square footage of the Leased
                                       Premises or the Property is changed,
                                       Tenant's Expense Share shall be
                                       recalculated to equal the percentage
                                       described in the first sentence of this
                                       paragraph, so that the aggregate Tenant's
                                       Expense Share of all tenants of the
                                       Property shall equal 100%. Tenant's
                                       Expense Share is subject to adjustment as
                                       set forth in Paragraphs 13.12(b) and
                                       13.12 (c).

        Base Monthly Rent:             The term "Base Monthly Rent" shall mean

                                   ARTICLE 2

                      LEASED PREMISES, TERM AND POSSESSION

2.1  Demise Of Leased Premises. Landlord hereby leases to Tenant and Tenant
hereby leases from Landlord for Tenant's own use in the conduct of Tenant's
business and not for purposes of speculating in real estate, for the Lease Term
and upon the terms and subject to the conditions of this Lease, that certain
interior space described in Article 1 as the Leased Premises, reserving and
excepting to Landlord (a) such access as may be required (including but not
limited to elevator access) by Landlord to the Building roof and heating,
ventilating, air conditioning, ducting, and cabling systems, (b) the right to
place additional vertical penetrations behind the walls of the Leased Premises
as needed for heating, ventilating, air conditioning, ducting, and cabling, and
(c) the right to fifty percent (50%) of all assignment consideration and excess
rentals as provided in Article 7 below. Tenant's lease of the Leased Premises,
together with the appurtenant non-exclusive right to use the Outside Areas as
described in Paragraph 2.2 below, shall be conditioned upon and be subject to
the continuing compliance by Tenant with (i) all the terms and conditions of
this Lease, (ii) all Laws and Private Restrictions governing the use or
occupancy of the Leased Premises and the Property, (iii) all easements and other
matters now of public record respecting the use of the Leased Premises and
Property, and (iv) all reasonable rules and regulations from time to time
established by Landlord. Notwithstanding any provision of this Lease to the
contrary, Landlord hereby reserves to itself and its designees all rights of
access, use and occupancy of the Building roof, and Tenant shall have no right
of access, use or occupancy of the Building roof except (if at all) to the
extent required in order to maintain and repair any of Tenant's equipment
located upon the roof as of the Effective Date of this Lease, or such equipment
as may thereafter be approved by Landlord in its reasonable discretion pursuant
to Section 4.14 below for placement in a Landlord-designated area upon the roof,
or to enable Tenant to perform Tenant's maintenance and repair obligations
pursuant to this Lease. Tenant shall not be required to pay rent or other
amounts to Landlord for the right to maintain its existing equipment on the roof
as of the Effective Date of this Lease.

2.2  Right To Use Outside Areas. As an appurtenant right to Tenant's right to
the use and occupancy of the Leased Premises, Tenant shall have the
non-exclusive right to use the Outside Areas in conjunction with its use of the
Leased Premises solely for the purposes for which they were designated and
intended and for no other purposes whatsoever. Tenant's right to so use the
Outside Areas shall be subject to the limitations on such use as set forth in
Article 1 and any rules and regulations established by Landlord pursuant to
Section 4.12 below, and shall terminate concurrently with any termination of
this Lease. Tenant shall at all times be entitled to use at least that number of
parking spaces determined by multiplying Tenant's Expense Share by the total
number of parking spaces then available upon the Property.

2.3  Lease Commencement Date And Lease Term. The term of this Lease shall begin,
and the Lease Commencement Date shall be deemed to have occurred, on the Closing
Date (the "Lease Commencement Date"). If the Lease Commencement Date is other
than the Intended Commencement Date, appropriate adjustments shall be made so
that all obligations under this Lease which are based on the Intended
Commencement Date, shall instead be based on the Lease Commencement Date. Within
five (5) days after the Lease Commencement Date has been determined, Landlord
and Tenant shall execute a Lease Commencement Date Certificate in the form of
Exhibit "C" attached hereto. The term of this Lease shall in all events end on
the Lease Expiration Date (as set forth in Article 1). The Lease Term shall be
that period of time commencing on the Lease Commencement Date and ending on the
Lease Expiration Date (the "Lease Term"). The parties intend that this Lease
shall be effective and binding on the parties as of the Effective Date of the
Lease; provided, however, because Landlord does not currently own fee title to
the Property, each of Landlord's and Tenant's rights and obligations hereunder
shall be conditioned upon the close of escrow whereupon Landlord acquires fee
title to the Property. A termination of the Purchase Agreement pursuant to its
terms shall automatically terminate this Lease.

2.4  Delivery Of Possession. Landlord shall deliver to Tenant possession of the
Leased Premises in its then "AS-IS" condition, "WITH ALL FAULTS," on the
Intended Commencement Date. If Landlord is unable to so deliver possession of
the Leased Premises to Tenant on or before the Intended Commencement Date,
Landlord shall not be in default under this Lease, nor shall this Lease be void,
voidable or cancelable by Tenant until the lapse of ninety (90) days after the
Intended Commencement Date (the "delivery grace period"). Additionally, the
delivery grace period above set forth shall be extended for such number of days
as Landlord may be delayed in delivering possession of the Leased Premises to
Tenant by reason of Force Majeure or the action or inaction of Tenant. If
Landlord is unable to deliver possession of the Leased Premises to Tenant within
the described delivery grace period (including any extension thereof by reason
of Force Majeure or the actions or inactions of Tenant), then Tenant's sole
remedy shall be to terminate this Lease by written notice delivered to Landlord
within ten days after the expiration of the delivery grace period (as extended,
if applicable), and in no event shall Landlord be liable in damages to Tenant
for such delay. Tenant may not terminate this Lease at any time after the date
Landlord notifies Tenant that the Leased Premises have been put into the agreed
condition and are available for delivery to Tenant, unless Landlord's notice is
not given in good faith.

2.5  No Improvement Work; Acceptance Of Possession. Landlord shall have no
obligation whatsoever to perform and construction or other improvements to
Leased Premises, nor to provide any allowances of any kind to Tenant on account
thereof. It is agreed that, by virtue of the Closing Date occurring, on the
Lease Commencement Date, Tenant formally accepts the Leased Premises and
acknowledges that the Leased Premises in their then "AS-IS" condition, "WITH ALL
FAULTS."

2.6  Surrender Of Possession. Immediately prior to the expiration or upon the
sooner termination of this Lease, Tenant shall remove all of Tenant's signs from
the exterior of the Building (the foregoing shall not imply any right to place
signs on the exterior of the Building, it being agreed that any such rights
shall be pursuant to Paragraph 4.6 below only), and shall remove all of Tenant's
equipment (excluding telecommunications wiring and cabling), trade fixtures,
furniture, supplies, wall decorations and other personal property from within
the Leased Premises, the

                                       3.

<PAGE>

Building and the Outside Areas, and shall vacate and surrender the Leased
Premises, the Building, the Outside Areas and the Property to Landlord in the
same condition, broom clean, as existed at the Lease Commencement Date,
reasonable wear and tear excepted. Tenant shall repair all damage to the Leased
Premises, the exterior of the Building and the Outside Areas caused by Tenant's
removal of Tenant's property. Tenant shall, with respect to telecommunications
wiring and cabling, leave the same in good condition and repair and labeled
and/or coded (to the extent labeled and coded as of the Effective Date of this
Lease) sufficiently so that Landlord can readily determine the origin,
destination and function of the wires and cables. Tenant shall patch and
refinish, to Landlord's reasonable satisfaction, all penetrations made by Tenant
or its employees to the floor, walls or ceiling of the Leased Premises (except
for nail holes used to hang pictures and artwork on the walls of the Leased
Premises), whether such penetrations were made with Landlord's approval or not.
Tenant shall repair all damage caused by Tenant to the exterior surface of the
Building and the paved surfaces of the Outside Areas and, where necessary,
replace or resurface same. Additionally, to the extent that Landlord shall have
notified or is deemed to have notified Tenant in writing at the time the
improvements were completed that it desired to have certain improvements made by
Tenant or at the request of Tenant removed at the expiration or sooner
termination of the Lease, Tenant shall, upon the expiration or sooner
termination of the Lease, remove any such improvements constructed or installed
by Landlord or Tenant and repair all damage caused by such removal. In no event
shall Tenant be required to remove any portions of the Leased Premises existing
as of the Effective Date of this Lease. If the Leased Premises, the Building,
the Outside Areas and the Property are not surrendered to Landlord in the
condition required by this paragraph at the expiration or sooner termination of
this Lease, Landlord may, at Tenant's expense, so remove Tenant's signs,
property and/or improvements not so removed and make such repairs and
replacements not so made or hire, at Tenant's expense, independent contractors
to perform such work. Tenant shall be liable to Landlord for all costs incurred
by Landlord in returning the Leased Premises, the Building and the Outside Areas
to the required condition, together with interest on all costs so incurred from
the date paid by Landlord at the then maximum rate of interest not prohibited or
made usurious by law until paid. Tenant shall pay to Landlord the amount of all
costs so incurred plus such interest thereon, within ten (10) business days of
Landlord's billing Tenant for same. Tenant shall indemnify Landlord against loss
or liability resulting from delay by Tenant in surrendering the Leased Premises,
including, without limitation, any claims made by any succeeding Tenant or any
losses to Landlord with respect to lost opportunities to lease to succeeding
tenants.

                                   ARTICLE 3

                    RENT, LATE CHARGES AND SECURITY DEPOSITS

3.1  Base Monthly Rent. Commencing on the Lease Commencement Date and continuing
throughout the Lease Term, Tenant shall pay to Landlord, without prior demand
therefor, in advance on the first day of each calendar month, the amount set
forth as "Base Monthly Rent" in Article 1 (the "Base Monthly Rent").

3.2  Additional Rent. Commencing on the Lease Commencement Date and continuing
throughout the Lease Term, in addition to the Base Monthly Rent and to the
extent not required by Landlord to be contracted for and paid directly by
Tenant, Tenant shall pay to Landlord as additional rent (the "Additional Rent")
the following amounts:

(a)  An amount equal to all Property Operating Expenses (as defined in Article
13) incurred by Landlord. Payment shall be made by whichever of the following
methods (or combination of methods) is (are) from time to time designated by
Landlord:

          (i)   Landlord may forward invoices or bills for such expenses to
Tenant, and Tenant shall, no later than the later of (A) ten (10) days prior to
the due date, and (B) fifteen (15) business days after delivery to Tenant, pay
such invoices or bills and deliver satisfactory evidence of such payment to
Landlord, and/or

          (ii)  Landlord may bill to Tenant, on a periodic basis not more
frequently than monthly, the amount of such expenses (or group of expenses) as
paid or incurred by Landlord, and Tenant shall pay to Landlord the amount of
such expenses within fifteen (15) business days after receipt of a written bill
therefor from Landlord, and/or

          (iii) Landlord may deliver to Tenant Landlord's reasonable estimate of
any given expense (such as Landlord's Insurance Costs or Real Property Taxes),
or group of expenses, which it anticipates will be paid or incurred for the
ensuing calendar or fiscal year, as Landlord may determine, and Tenant shall pay
to Landlord an amount equal to the estimated amount of such expenses for such
year in equal monthly installments during such year with the installments of
Base Monthly Rent. Landlord reserves the right to revise such estimate from time
to time.

Landlord reserves the right to change from time to time the methods of billing
Tenant for any given expense or group of expenses or the periodic basis on which
such expenses are billed.

     (b)  Landlord's share of the consideration received by Tenant upon certain
assignments and sublettings as required by Article 7.

     (c)  Any legal fees and costs that Tenant is obligated to pay or reimburse
to Landlord pursuant to Article 13; and

     (d)  Any other charges or reimbursements due Landlord from Tenant pursuant
to the terms of this Lease.

Notwithstanding the foregoing, Landlord may elect by written notice to Tenant to
have Tenant pay Real Property Taxes or any portion thereof directly to the
applicable taxing authority, in which case Tenant shall make such

                                       4.

<PAGE>

payments and deliver satisfactory evidence of payment to Landlord no later than
ten (10) days before such Real Property Taxes become delinquent.

After Tenant's receipt of the year-end statement described in Paragraph 3.3
above setting forth the annual reconciliation of the Property Operating
Expenses, if Tenant has a basis for suspecting that Landlord may have
overcharged Tenant for Property Operating Expenses, Tenant shall so notify
Landlord and provide Landlord with such basis. Landlord and Tenant shall
thereafter promptly meet and confer and attempt in good faith to resolve any
differences regarding such possible overcharges. If they are unable to resolve
such differences, Tenant may cause an audit of Landlord's books and records to
determine the accuracy of Landlord's billings for Property Operating Expenses
under this Lease, provided (a) such audit is performed by a "Big Five"
accounting firm with no present or prior relationship with Tenant, (b) there is
no contingency compensation, and (c) such audit is commenced within sixty (60)
days after Tenant's receipt of the year-end statement described above. If such
audit reveals that the actual Property Operating Expenses for any given year
were less than the amount that Tenant paid for Property Operating Expenses for
any such year, then Landlord shall credit the excess to Tenant's next payment of
Additional Rent. If such audit reveals that the actual Property Operating
Expenses for any given year were more than the amount that Tenant paid for
Property Operating Expenses for any such year, Tenant shall pay such amount to
Landlord within thirty (30) days after completion of the audit. If such audit
establishes that Property Operating Expenses have been overstated by more than
seven percent (7%), Landlord shall reimburse Tenant for the reasonable costs and
expenses of the audit, in no event to exceed $5,000.

3.3  Year-End Adjustments. If Landlord shall have elected to bill Tenant for the
Property Operating Expenses (or any group of such expenses) on an estimated
basis in accordance with the provisions of Paragraph 3.2(a)(iii) above, Landlord
shall furnish to Tenant within three months following the end of the applicable
calendar or fiscal year, as the case may be, a statement setting forth (i) the
amount of such expenses paid or incurred during the just ended calendar or
fiscal year, as appropriate, and (ii) the amount that Tenant has paid to
Landlord for credit against such expenses for such period. If Tenant shall have
paid more than its obligation for such expenses for the stated period, Landlord
shall, at its election, either (i) credit the amount of such overpayment toward
the next ensuing payment or payments of Additional Rent that would otherwise be
due or (ii) refund in cash to Tenant the amount of such overpayment within
thirty (30) days after its determination. If such year-end statement shall show
that Tenant did not pay its obligation for such expenses in full, then Tenant
shall pay to Landlord the amount of such underpayment within thirty (30) days
from Landlord's billing of same to Tenant. The provisions of this Paragraph
shall survive the expiration or sooner termination of this Lease.

3.4  Late Charge, And Interest On Rent In Default. Tenant acknowledges that the
late payment by Tenant of any monthly installment of Base Monthly Rent or any
Additional Rent will cause Landlord to incur certain costs and expenses not
contemplated under this Lease, the exact amounts of which are extremely
difficult or impractical to fix. Such costs and expenses will include without
limitation, administration and collection costs and processing and accounting
expenses. Therefore, if any installment of Base Monthly Rent is not received by
Landlord from Tenant within five (5) calendar days after the same becomes due,
Tenant shall immediately pay to Landlord a late charge in an amount equal to the
amount set forth in Article 1 as the "Late Charge Amount," and if any Additional
Rent is not received by Landlord when the same becomes due, Tenant shall
immediately pay to Landlord a late charge in an amount equal to 4% of the
Additional Rent not so paid; provided, however, that once but only once in any
twelve (12) month period during the Lease Term, Tenant shall be entitled to
written notice of non-receipt of Base Monthly Rent or Additional Rent from
Landlord, and Tenant shall not be liable for any Late Charge Amount or other
late charge hereunder if such installment of Base Monthly Rent or Additional
Rent is received by Landlord within three (3) days after Tenant's receipt of
such notice from Landlord. Landlord and Tenant agree that this late charge
represents a reasonable estimate of such costs and expenses and is fair
compensation to Landlord for the anticipated loss Landlord would suffer by
reason of Tenant's failure to make timely payment. In no event shall this
provision for a late charge be deemed to grant to Tenant a grace period or
extension of time within which to pay any rental installment or prevent Landlord
from exercising any right or remedy available to Landlord upon Tenant's failure
to pay each rental installment due under this Lease when due, including the
right to terminate this Lease. If any rent remains delinquent for a period in
excess of five (5) calendar days, then, in addition to such late charge, Tenant
shall pay to Landlord interest on any rent that is not so paid from said tenth
day at the then maximum rate of interest not prohibited or made usurious by Law
until paid.

3.5  Payment Of Rent. Except as specifically provided otherwise in this Lease,
all rent shall be paid in lawful money of the United States, without any
abatement, reduction or offset for any reason whatsoever, to Landlord at such
address as Landlord may designate from time to time. Tenant's obligation to pay
Base Monthly Rent and all Additional Rent shall be appropriately prorated at the
commencement and expiration of the Lease Term. The failure by Tenant to pay any
Additional Rent as required pursuant to this Lease when due shall be treated the
same as a failure by Tenant to pay Base Monthly Rent when due, and Landlord
shall have the same rights and remedies against Tenant as Landlord would have
had Tenant failed to pay the Base Monthly Rent when due.

3.6  Prepaid Rent. Tenant shall, upon execution of this Lease, pay to Landlord
the amount set forth in Article 1 as "First Month's Prepaid Rent" as prepayment
of rent for credit against the first payment of Base Monthly Rent due hereunder.

3.7  Security Deposit.

          (a)   Tenant shall deposit, prior to the close of escrow pursuant to
the Purchase Agreement, with Landlord the amount set forth in Article 1 as the
"Security Deposit" as security for the performance by Tenant of the terms of
this Lease to be performed by Tenant, and not as prepayment of rent. Tenant
hereby grants to Landlord a security interest in the Security Deposit, including
but not limited to replenishments thereof. Landlord may apply such portion or
portions of the Security Deposit as are reasonably necessary for the following
purposes: (i) to remedy any default by Tenant in the payment of Base Monthly
Rent or Additional Rent or a late charge or interest on defaulted

                                       5.

<PAGE>

rent, or any other monetary payment obligation of Tenant under this Lease; (ii)
to repair damage to the Leased Premises, the Building or the Outside Areas
caused or permitted to occur by Tenant; (iii) to clean and restore and repair
the Leased Premises, the Building or the Outside Areas following their surrender
to Landlord if not surrendered in the condition required pursuant to the
provisions of Article 2, and (iv) to remedy any other default of Tenant to the
extent permitted by Law including, without limitation, paying in full on
Tenant's behalf any sums claimed by materialmen or contractors of Tenant to be
owing to them by Tenant for work done or improvements made at Tenant's request
to the Leased Premises. In this regard, Tenant hereby waives any restriction on
the uses to which the Security Deposit may be applied as contained in Section
1950.7(c) of the California Civil Code and/or any successor statute. In the
event the Security Deposit or any portion thereof is so used, Tenant shall pay
to Landlord, promptly upon demand, an amount in cash sufficient to restore the
Security Deposit to the full original sum. If Tenant fails to promptly restore
the Security Deposit and if Tenant shall have paid to Landlord any sums as "Last
Month's Prepaid Rent," Landlord may, in addition to any other remedy Landlord
may have under this Lease, reduce the amount of Tenant's Last Month's Prepaid
Rent by transferring all or portions of such Last Month's Prepaid Rent to
Tenant's Security Deposit until such Security Deposit is restored to the amount
set forth in Article 1. Landlord shall not be deemed a trustee of the Security
Deposit. Landlord may use the Security Deposit in Landlord's ordinary business
and shall not be required to segregate it from Landlord's general accounts.
Tenant shall not be entitled to any interest on the Security Deposit. If
Landlord transfers the Building or the Property during the Lease Term, Landlord
may pay the Security Deposit to any subsequent owner in conformity with the
provisions of Section 1950.7 of the California Civil Code and/or any successor
statute, in which event the transferring landlord shall be released from all
liability for the return of the Security Deposit. Tenant specifically grants to
Landlord (and Tenant hereby waives the provisions of California Civil Code
Section 1950.7 to the contrary) a period of sixty (60) days following a
surrender of the Leased Premises by Tenant to Landlord within which to inspect
the Leased Premises, make required restorations and repairs, receive and verify
workmen's billings therefor, and prepare a final accounting with respect to the
Security Deposit. In no event shall the Security Deposit or any portion thereof,
be considered prepaid rent.

        (b) Notwithstanding the foregoing, at Tenant's option, Tenant may
deliver to Landlord a clean, unconditional, irrevocable, transferable letter of
credit in lieu of cash for the Security Deposit (the "Letter of Credit") in form
and issued by a financial institution ("Issuer") satisfactory to Landlord in its
sole discretion, substantially in the form attached as Exhibit "D." The Letter
of Credit shall permit partial draws, and provide that draws thereunder will be
honored upon presentation by Landlord. The Letter of Credit shall have an
expiration period of one (1) year but shall automatically renew by its terms
unless affirmatively cancelled by either Issuer or Tenant, in which case Issuer
must provide Landlord 30 days' prior written notice of such expiration or
cancellation. The Letter of Credit shall remain in effect until seventy-five
(75) days after the Lease Expiration Date. Any amount drawn under the Letter of
Credit and not utilized by Landlord for the purposes permitted by this Lease
shall be held in accordance with subparagraph (a) of this Paragraph 3.7. If the
Tenant fails to renew or replace the Letter of Credit as required under this
Lease at least thirty (30) days before its stated expiration date, Landlord may
draw upon the entire amount of the Letter of Credit. No fees applicable to the
Letter of Credit shall be charged to Landlord.

        (c) At the beginning of the seventy-third (73rd) month of the Lease
Term, provided Tenant is then rated as an "investment grade" credit by a
reputable, New York-based rating agency, Tenant shall have the right to have the
amount of the Security Deposit or Letter of Credit reduced by Two Hundred Fifty
Thousand Dollars ($250,000) (but not to an amount below $250,000) and at the
beginning of the ninety-seventh (97th) month of the Lease Term, to have the
amount of the Security Deposit or Letter of Credit further reduced by Two
Hundred Fifty Thousand Dollars ($250,000) (but not to an amount below $250,000).
Notwithstanding the foregoing, there shall be no reduction under this paragraph
of the required amount of the Security Deposit or Letter of Credit if an uncured
default has occurred and is continuing on such date(s).

reason of, or under claim of, the express or implied authority or consent of
Tenant, then Tenant, upon demand of Landlord, shall restrain, to the fullest
extent then allowed by Law, such unauthorized use, and shall initiate such
appropriate proceedings as may be required to so restrain such use. Landlord

for any diminution in Tenant's right to use the Outside Areas as a result.

in contamination or deterioration of water or soil, then Tenant shall promptly
take any and all action necessary to clean up such contamination, but the
foregoing shall in no event be deemed to constitute permission by Landlord to

there has been any release or the presence of Hazardous Materials in the ground
or ground water on the Leased Premises which did not exist upon commencement of
the Lease Term, Tenant shall have the right to conduct appropriate tests of
water and soil and to deliver to Landlord the results of such tests to
demonstrate that no contamination in excess of permitted levels has occurred as
a result of Tenant's use of the Leased Premises. Tenant shall further be solely
responsible for, and shall defend, indemnify, and hold Landlord and its agents
harmless from and against all claims, costs and liabilities, including
attorneys' fees and costs, arising out of or in connection with any removal,
cleanup and restoration work and materials required hereunder to return the

behalf of Tenant relating to the storage, use, disposal or transportation of
Hazardous Materials to be removed from the property and transported for use,
storage or disposal in accordance and compliance with all Laws and other
requirements respecting Hazardous Materials used or permitted to be used by
Tenant. Tenant shall apply for and shall obtain from all appropriate regulatory
authorities (including any applicable fire department or regional water quality
control board) all permits, approvals and clearances necessary for the closure
of the Property and shall take all other actions as may be required to complete
the closure of the Building and the Property.

        (d) At any time prior to expiration of the Lease term, subject to
reasonable prior written (including e-mail) notice (not less than forty-eight
(48) hours) and Tenant's reasonable security requirements and provided such
activities do not unreasonably interfere with the conduct of Tenant's business
at the Leased Premises, Landlord shall have the right to enter in and upon the
Property, Building and Leased Premises in order to conduct appropriate tests of
water and soil to determine whether levels of any Hazardous Materials in excess
of legally permissible levels has occurred as a result of Tenant's use thereof.
Landlord shall furnish copies of all such test results and reports to Tenant
and, at Tenant's option and cost, shall permit split sampling for testing and
analysis by Tenant. Such testing shall be at Tenant's expense if Landlord has a
reasonable basis for suspecting and confirms the presence of Hazardous Materials
in the soil or surface or ground water in, on, under, or about the Property, the
Building or the Leased Premises, which has been caused by or resulted from the
activities of Tenant, its agents, contractors, or invitees.

        (e) Landlord may voluntarily cooperate in a reasonable manner with the

thereto respecting the use of the Leased Premises and the Outside Areas for the
care and orderly management of the Property. Upon delivery to Tenant of a copy
of such rules and regulations or any amendments or additions thereto, Tenant
shall comply with such rules and regulations, provided that such Rules and
Regulations shall be enforced in a non-discriminatory manner on all tenants of
the Building. A violation by Tenant of any of such rules and regulations shall
constitute a default by Tenant under this Lease. If there is a conflict between
the rules and regulations and any of the provisions of this Lease, the
provisions of this Lease shall prevail. Landlord shall not be responsible or
liable to Tenant for the violation of such rules and regulations by any other
tenant of the Property. A copy of the initial Rules and Regulations is attached

without the consent or joinder of Tenant, such easements, rights of way and
dedications that Landlord deems necessary, and to cause the recordation of
parcel maps and restrictions, so long as such easements, rights of way and
dedications do not materially interfere with the use of or access to the Leased
Premises by Tenant. Tenant agrees to execute any documents reasonably requested
by Landlord to effectuate any such easement rights, dedications, maps or
restrictions.

as hereinafter set forth (provided however that Landlord shall have the right to
reasonably relocate the same at no out-of-pocket cost to Tenant), and provided
such installation does not impact the structural integrity of the Building.

unreasonably withheld, conditioned or delayed, place the Roof Equipment in one
or two (but not more than two) locations on the roof which in the aggregate do
not contain more than 1,250 square feet, which do not interfere with other
tenants' or Landlord's roof equipment, and which do not result in any additional

heating, air conditioning and ventilating system of the Building is designed to
operate efficiently while electrical equipment such as customary lamps,
typewriters and other small fractional horsepower office machines are being used
in the Leased Premises and while the Leased Premises are occupied in any
Building System zone by not more than one person per one hundred square feet of
rentable area of the Leased Premises. If the temperature otherwise maintained in
any portion of the Leased Premises by the heating, air conditioning and
ventilating system of the Building is affected by (i) Tenant's use of any
lights, machines or equipment (including, without limitation, computers,
electronic data processing machines and copying machines), or (ii) the occupancy
of the Leased Premises by more than one person per one hundred square feet of
rentable area of the Leased Premises, or (iii) an electrical load that generates
heat in excess of normal office usage,

                                       10.

Landlord shall have the right, unless Tenant ceases and desists from such usage
or excess occupancy within five (5) days after written notice from Landlord, to
install any machinery and equipment that Landlord reasonably deems necessary to
restore temperature balance, including, without limitation, supplemental and
independent heating, air conditioning and ventilation systems and/or
modifications to the standard air conditioning equipment, and the cost thereof,
including the cost of installation and any additional cost of operation and
maintenance incurred thereby, shall be paid by Tenant to Landlord within five
(5) days after demand therefor by Landlord. Tenant shall notify Landlord in
advance, prior to installing or operating any machines or equipment, of the
specifications of such machines or equipment which could so affect the
temperature otherwise maintained in any portion of the Leased Premises by the
heating, air conditioning and ventilating system of the Building. In addition,
Tenant shall pay Landlord the amount of $30 per hour for Building standard HVAC
usage during any times other than Building Standard Hours. Tenant must notify
Landlord by Thursday at 5:00 p.m. as to what weekend usage Tenant will require.

        (b) Unless and until Landlord has caused the Leased Premises to be
separately metered, this subparagraph (b) shall apply and subparagraph (c) below
shall be inapplicable.

               (i)   Landlord will furnish to the Leased Premises during
Building Standard Hours, and subject to rules and regulations from time to time
established by Landlord: (a) elevator service, (b) electric current in amounts
required for normal lighting by building standard overhead fluorescent fixtures,
and (c) water for lavatory and drinking purposes. Landlord will charge Tenant as
Additional Rent for such utilities based on a reasonable allocation to the
Leased Premises of the utility costs incurred by Landlord. It is understood that
subject to subparagraphs (ii) and (iii) below, such elevator service, electric
current and water will be available twenty-four (24) hours a day.

               (ii)  In the event any governmental entity promulgates or revises
any statute, ordinance or building, fire or other code or imposes mandatory or
voluntary controls or guidelines on Landlord or the Building or any part
thereof, or Landlord's engineers propose guidelines or otherwise make
recommendations, relating to the use or conservation of energy, water, gas,
light or electricity or the reduction of automobile or other emissions or the
provision of any other utility or service provided with respect to this Lease,
or in the event Landlord is required or elects to make alterations or to perform
maintenance with respect to, any part of the Property in order to comply with
such mandatory or voluntary controls, guidelines or recommendations, such
compliance, the making of such alterations and/or the performance of such
maintenance shall in no event entitle Tenant to any damages, relieve Tenant of
the obligation to pay the full Base Monthly Rent and Additional Rent reserved
hereunder or to perform each of its other covenants hereunder or constitute or
be construed as a constructive or other eviction of Tenant.

               (iii) Without the prior written consent of Landlord, which
Landlord may refuse in its sole discretion, the electrical current available to
the Leased Premises for both lighting and power (excluding the central heating,
air conditioning and ventilating system) shall at no time exceed a connected
load of 4 watts per square foot of usable area of the Leased Premises. Without
the prior written consent of Landlord, which Landlord may refuse in its sole
discretion, Tenant shall not: (a) connect or use any electrical equipment that
exceeds the capacity of the Building electrical system; (b) connect any
apparatus, machine or device through electrical outlets except in the manner for
which such outlets are designed and without the use of any device intended to
increase the plug capacity of any electrical outlet; or (c) maintain at any time
an electrical demand load in excess of 4 watts per square foot of rentable area
of the Leased Premises. At any time that Tenant's use of electricity exceeds the
foregoing limits, Landlord shall have the right to impose a reasonable charge,
as determined by Landlord, for such excess use. Landlord shall have the right at
any time to install an electric current meter in the Leased Premises or
otherwise to measure the amount of electric current consumed on the Leased
Premises, and the cost of such meter or other corrective measures and the
installation and maintenance thereof shall be paid for by Tenant.

        (c) At such time as Landlord has caused the Leased Premises to be
separately metered, (which it is authorized to do at the sole expense of
Tenant), this subparagraph (c) shall apply and subparagraph (b) above shall be
inapplicable.

               (i)   Landlord shall arrange for gas and electricity connections
to the Building.

               (ii)  Tenant shall arrange at its sole cost and expense and in
its own name, for the supply of gas and electricity to the Leased Premises.

        (d) Landlord shall maintain the water meter(s) in its own name;
provided, however, that if at any time during the Lease Term Landlord shall
require Tenant to put the water service in Tenant's name, Tenant shall do so at
Tenant's sole cost. Tenant shall be responsible for determining if the local
supplier of water, gas and electricity can supply the needs of Tenant and
whether or not the existing water, gas and electrical distribution systems
within the Building and the Leased Premises are adequate for Tenant's needs.
Tenant shall be responsible for determining if the existing sanitary and storm
sewer systems now servicing the Leased Premises and the Property are adequate
for Tenant's needs. Tenant shall pay all charges for water, gas, electricity and
storm and sanitary sewer services as so supplied to the Leased Premises,
irrespective of whether or not the services are maintained in Landlord's or
Tenant's name.

5.3 Security. Tenant acknowledges that Landlord has not undertaken any duty
whatsoever to provide security for the Leased Premises, the Building, the
Outside Areas or the Property and, accordingly, Landlord is not responsible for
the security of same or the protection of Tenant's property or Tenant's
employees, invitees or contractors. To the extent Tenant determines that such
security or protection services are advisable or necessary, Tenant shall arrange
for and pay the costs of providing same. In the event Landlord agrees to provide
any security services, whether it be guard service or secure access systems or
otherwise, Landlord shall do so strictly as an accommodation

                                       11.

<PAGE>

to Tenant and Landlord shall have no liability whatsoever in connection
therewith, whether it be for failure to maintain the secure access system, or
for failure of the guard service to provide adequate security, or otherwise.
Without limitation, Paragraph 8.1 below is intended by Tenant and Landlord to
apply to this Paragraph 5.3.

5.4 Energy And Resource Consumption. Landlord may voluntarily cooperate in a
reasonable manner with the efforts of governmental agencies and/or utility
suppliers in reducing energy or other resource consumption within the Property.
Tenant shall not be entitled to terminate this Lease or to any reduction in or
abatement of rent by reason of such compliance or cooperation. Tenant agrees at
all times to cooperate fully with Landlord and to abide by all reasonable rules
established by Landlord (i) in order to maximize the efficient operation of the
electrical, heating, ventilating and air conditioning systems and all other
energy or other resource consumption systems with the Property and/or (ii) in
order to comply with the requirements and recommendations of utility suppliers
and governmental agencies regulating the consumption of energy and/or other
resources.

5.5 Limitation Of Landlord's Liability. Landlord shall not be liable to Tenant
for injury to Tenant, its employees, agents, invitees or contractors, damage to
Tenant's property or loss of Tenant's business or profits, nor shall Tenant be
entitled to terminate this Lease or to any reduction in or abatement of rent by
reason of (i) Landlord's failure to provide security services or systems within
the Property for the protection of the Leased Premises, the Building or the
Outside Areas, or the protection of Tenant's property or Tenant's employees,
invitees, agents or contractors, or (ii) Landlord's failure to perform any
maintenance or repairs to the Leased Premises, the Building, the Outside Areas
or the Property (other than by reason of Landlord's gross negligence or willful
misconduct) until Tenant shall have first notified Landlord, in writing, of the
need for such maintenance or repairs, and then only after Landlord shall have
had a reasonable period of time following its receipt of such notice within
which to perform such maintenance or repairs, or (iii) any failure,
interruption, rationing or other curtailment in the supply of water, electric
current, gas or other utility service to the Leased Premises, the Building, the
Outside Areas or the Property from whatever cause (other than Landlord's sole
active negligence or willful misconduct), or (iv) the unauthorized intrusion or
entry into the Leased Premises by third parties (other than Landlord).
Notwithstanding the foregoing, if (i) utility services are unavailable to the
Leased Premises for a period of ten (10) or more consecutive days and (ii) the
unavailability of such utilities substantially interferes with Tenant's ability
to operate within the Leased Premises, and (iii) Landlord carries rental
interruption insurance and is able to and does collect rental interruption
insurance proceeds covering the Rent under this Lease, then Rent hereunder shall
abate to the extent of the rental interruption insurance proceeds collected by
Landlord.

                                    ARTICLE 6

                          ALTERATIONS AND IMPROVEMENTS

6.1 By Tenant. Tenant shall not make any alterations to or modifications of the
Leased Premises or construct any improvements within the Leased Premises until
Landlord shall have first approved, in writing, the plans and specifications
therefor, which approval may be withheld in Landlord's sole discretion, except
that if Tenant's alterations, modifications, or improvements are generic (and
not specialized) in nature and are generally reusable by other likely tenants of
the Leased Premises in Landlord's reasonable opinion, then such approval shall
not be unreasonably withheld, delayed or conditioned. Tenant's written request
shall also contain a request for Landlord to elect whether or not it will
require Tenant to remove the subject alterations, modifications or improvements
at the expiration or earlier termination of this Lease. If such additional
request is not included, Landlord may make such election at the expiration or
earlier termination of this Lease (and for purposes of Tenant's removal
obligations set forth in Paragraph 2.6 above, Landlord shall be deemed to have
made the election at the time the alterations, modifications or improvements
were completed). All such modifications, alterations or improvements, once so
approved, shall be made, constructed or installed by Tenant at Tenant's expense
(including all permit fees and governmental charges related thereto), using a
licensed contractor first approved by Landlord, in substantial compliance with
the Landlord-approved plans and specifications therefor. All work undertaken by
Tenant shall be done in accordance with all Laws and in a good and workmanlike
manner using new materials of good quality. Tenant shall not commence the making
of any such modifications or alterations or the construction of any such
improvements until (i) all required governmental approvals and permits shall
have been obtained, (ii) all requirements regarding insurance imposed by this
Lease have been satisfied, (iii) Tenant shall have given Landlord at least five
(5) business days prior written notice of its intention to commence such work so
that Landlord may post and file notices of non-responsibility, and (iv) if
requested by Landlord, for any alteration or modification exceeding One Hundred
Thousand Dollars ($100,000) in cost, Tenant shall have obtained contingent
liability and broad form builder's risk insurance in an amount satisfactory to
Landlord in its reasonable discretion to cover any perils relating to the
proposed work not covered by insurance carried by Tenant pursuant to Article 9.
In no event shall Tenant make any modification, alterations or improvements
whatsoever to the Outside Areas or the exterior or structural components of the
Building including, without limitation, any cuts or penetrations in the floor,
roof or exterior walls of the Leased Premises. As used in this Article, the term
"modifications, alterations and/or improvements" shall include, without
limitation, the installation of additional electrical outlets, overhead lighting
fixtures, drains, sinks, partitions, doorways, or the like. Subject to Tenant's
repair and restoration obligations, Tenant shall be entitled to make interior,
non-structural alterations to the Leased Premises which do not exceed either
Seventy Thousand Dollars ($70,000) in cost per project or Two Hundred Fifty
Thousand Dollars ($250,000) in cost in the aggregate, without obtaining
Landlord's prior written consent.

6.2 Ownership Of Improvements. All modifications, alterations and improvements
made or added to the Leased Premises by Tenant (other than Tenant's inventory,
equipment, movable furniture, wall decorations and trade fixtures) shall be
deemed real property and a part of the Leased Premises, but shall remain the
property of Tenant during the Lease, and Tenant hereby covenants and agrees not
to grant a security interest in any such items to any party other than Landlord.
Any such modifications, alterations or improvements, once completed, shall not
be altered or removed from the Leased Premises during the Lease Term without
Landlord's written approval first obtained in accordance with the provisions of
Paragraph 6.1 above. At the expiration or sooner termination of this

                                       12.

<PAGE>

Lease, all such modifications, alterations and improvements other than Tenant's
inventory, equipment, movable furniture, wall decorations and trade fixtures,
shall automatically become the property of Landlord and shall be surrendered to
Landlord as part of the Leased Premises as required pursuant to Article 2,
unless Landlord shall require Tenant to remove any of such modifications,
alterations or improvements in accordance with the provisions of Article 2, in
which case Tenant shall so remove same. Landlord shall have no obligations to
reimburse Tenant for all or any portion of the cost or value of any such
modifications, alterations or improvements so surrendered to Landlord. All
modifications, alterations or improvements which are installed or constructed on
or attached to the Leased Premises by Landlord and/or at Landlord's expense
shall be deemed real property and a part of the Leased Premises and shall be
property of Landlord. All lighting, plumbing, electrical, heating, ventilating
and air conditioning fixtures, partitioning, window coverings, wall coverings
and floor coverings installed by Tenant shall be deemed improvements to the
Leased Premises and not trade fixtures of Tenant.

6.3 Alterations Required By Law. Tenant shall make all modifications,
alterations and improvements to the Leased Premises, at its sole cost, that are
required by any Law because of (i) Tenant's use or occupancy of the Leased
Premises, the Building, the Outside Areas or the Property, (ii) Tenant's
application for any permit or governmental approval, or (iii) Tenant's making of
any modifications, alterations or improvements to or within the Leased Premises.
If Landlord shall, at any time during the Lease Term, be required by any
governmental authority to make any modifications, alterations or improvements to
the Building or the Property, the cost incurred by Landlord in making such
modifications, alterations or improvements, including interest at a rate equal
to the greater of (a) 12%, or (b) the sum of that rate quoted by Wells Fargo
Bank, N.T. & S.A. from time to time as its prime rate, plus two percent (2%)
("Wells Prime Plus Two") (but in no event more than the maximum rate of interest
not prohibited or made usurious), shall be amortized by Landlord over the useful
life of such modifications, alterations or improvements, as determined in
accordance with generally accepted accounting principles, and the monthly
amortized cost of such modifications, alterations and improvements as so
amortized shall be considered a Property Maintenance Cost.

6.4 Liens. Tenant shall keep the Property and every part thereof free from any
lien, and shall pay when due all bills arising out of any work performed,
materials furnished, or obligations incurred by Tenant, its agents, employees or
contractors relating to the Property. If any such claim of lien is recorded
against Tenant's interest in this Lease, the Property or any part thereof,
Tenant shall bond against, discharge or otherwise cause such lien to be entirely
released within ten business days after the same has been recorded. Tenant's
failure to do so shall be conclusively deemed a material default under the terms
of this Lease.

                                    ARTICLE 7

                       ASSIGNMENT AND SUBLETTING BY TENANT

7.1 By Tenant. Tenant shall not sublet the Leased Premises or any portion
thereof or assign its interest in this Lease, whether voluntarily or by
operation of Law, without Landlord's prior written consent which shall not be
unreasonably withheld, conditioned or delayed. Any attempted subletting or
assignment without Landlord's prior written consent, at Landlord's election,
shall constitute a default by Tenant under the terms of this Lease. The
acceptance of rent by Landlord from any person or entity other than Tenant, or
the acceptance of rent by Landlord from Tenant with knowledge of a violation of
the provisions of this paragraph, shall not be deemed to be a waiver by Landlord
of any provision of this Article or this Lease or to be a consent to any
subletting by Tenant or any assignment of Tenant's interest in this Lease.
Without limiting the circumstances in which it may be reasonable for Landlord to
withhold its consent to an assignment or subletting, Landlord and Tenant
acknowledge that it shall be reasonable for Landlord to withhold its consent in
the following instances:

        (a) the proposed assignee or sublessee is a governmental agency;

        (b) in Landlord's reasonable judgment, the use of the Leased Premises by
the proposed assignee or sublessee would involve occupancy by other than for a
Permitted Use, would entail any alterations which would lessen the value of the
leasehold improvements in the Leased Premises, or would require increased
services by Landlord;

        (c) in Landlord's reasonable judgment, the credit-worthiness of the
proposed assignee is less than that of Tenant or does not meet the credit
standards applied by Landlord;

        (d) the proposed assignee or sublessee (or any of its affiliates) has
been in material default under a lease, has been in litigation with a previous
landlord, or in the ten years prior to the assignment or sublease has filed for
bankruptcy protection, has been the subject of an involuntary bankruptcy, or has
been adjudged insolvent;

        (e) Landlord has experienced a previous default by or is in litigation
with the proposed assignee or sublessee;

        (f) in Landlord's reasonable judgment, the Leased Premises, or the
relevant part thereof, will be used in a manner that will violate any negative
covenant as to use contained in this Lease;

        (g) the use of the Leased Premises by the proposed assignee or sublessee
will violate any applicable law, ordinance or regulation;

        (h) the proposed assignee or sublessee is, as of the date of this Lease,
a tenant in the Building;

                                       13.

<PAGE>

        (i) the proposed assignment or sublease fails to include all of the
terms and provisions required to be included therein pursuant to this Article 7;

        (j) in the case of a subletting of less than the entire Leased Premises,
if the subletting would result in the division of the Leased Premises into more
than two subparcels per floor or would require improvements to be made outside
of the Leased Premises; or

        (k) in the case of a subletting of less than an entire floor of the
Leased Premises, such subletting or the marketing activity relating thereto
commenced prior to January 1, 2003.

7.2 Merger, Reorganization, or Sale of Assets.

        (a) Subject to subparagraph (b) below: Any dissolution, merger,
consolidation or other reorganization of Tenant, or the sale or other transfer
in the aggregate over the Lease Term of a controlling percentage of the capital
stock of Tenant, or the sale or transfer of all or a substantial portion of the
assets of Tenant, shall be deemed a voluntary assignment of Tenant's interest in
this Lease. The phrase "controlling percentage" means the ownership of and the
right to vote stock possessing more than fifty percent of the total combined
voting power of all classes of Tenant's capital stock issued, outstanding and
entitled to vote for the election of directors. If Tenant is a partnership, a
withdrawal or change, voluntary, involuntary or by operation of Law, of any
general partner, or the dissolution of the partnership, shall be deemed a
voluntary assignment of Tenant's interest in this Lease. Upon Landlord's request
from time to time, Tenant shall promptly provide Landlord with a statement
certified by the Tenant's chief operating officer, which shall provide the
following information: (a) the names of all of Tenant's shareholders and their
ownership interests at the time thereof, provided Tenant's shares are not
publicly traded; (b) the state in which Tenant is incorporated; (c) the location
of Tenant's principal place of business; (d) information regarding a material
change in the corporate structure of Tenant, including, without limitation, a
merger or consolidation; and (e) any other information regarding Tenant's
ownership that Landlord reasonably requests. In the event of an acquisition by
one entity of the controlling percentage of the capital stock of Tenant where
this Lease is not assigned to such entity, it shall be a condition to Landlord's
consent to such change in control that such entity acquiring the controlling
percentage assume, as a primary obligor, all rights and obligations of Tenant
under this Lease (and such entity shall execute all documents reasonably
required to effectuate such assumption).

        (b) Notwithstanding subparagraph (a) above, over-the-counter stock
market transactions shall not be deemed to be assignments under this Lease. In
addition, provided that the conditions described below in this sentence have
been satisfied prior to or upon such assignment or subleasing, Tenant may,
without Landlord's prior written consent, sublet the Leased Premises or assign
this Lease to (i) a subsidiary, affiliate, division, corporation or joint
venture controlling, controlled by or under common control with Tenant, (ii) a
successor entity resulting from a merger, consolidation, or nonbankruptcy
reorganization by Tenant, or (iii) a purchaser of substantially all of Tenant's
assets located in the Leased Premises, provided that (A) the successor entity,
assignee, purchaser or subtenant has a net worth and a liquid net worth equal to
or greater than those of Tenant prior to the Effective Date of this Lease and
assumes in writing for the benefit of Landlord, this Lease and all of Tenant's
obligations under this Lease, and (B) the entity with the greatest net worth
involved directly or indirectly in the ownership and/or control of the
acquiring, merged, reorganized, or consolidated entity (hereafter, the "Assignee
Affiliate") shall have unconditionally assumed in writing for the benefit of
Landlord, this Lease and all of Tenant's obligations under this Lease. If any
assignment or subleasing occurs without such an assumption and without
Landlord's consent as provided in Paragraph 7.1 above, then the Assignee
Affiliate (and the successor entity, assignee, purchaser or subtenant) shall for
all purposes be deemed to have unconditionally assumed in writing for the
benefit of Landlord, this Lease and all of Tenant's obligations under this
Lease. In all events, Tenant shall remain fully liable under this Lease.

7.3 Landlord's Election. If Tenant shall desire to assign its interest under the
Lease or to sublet the Leased Premises, Tenant must first notify Landlord, in
writing, of its intent to so assign or sublet, at least thirty (30) days in
advance of taking any action with respect thereto. Once Tenant (or Landlord or
both pursuant to the joint marketing election described below) has identified a
potential assignee or sublessee, Tenant shall notify Landlord, in writing, of
its intent to so assign or sublet, at least thirty (30) days in advance of the
date it intends to so assign its interest in this Lease or sublet the Leased
Premises but not sooner than one hundred eighty days in advance of such date,
specifying in detail the terms of such proposed assignment or subletting,
including the name of the proposed assignee or sublessee, the proposed
assignee's or sublessee's intended use of the Leased Premises, current financial
statements (including a balance sheet, income statement and statement of cash
flow, all prepared in accordance with generally accepted accounting principles)
of such proposed assignee or sublessee, the form of documents to be used in
effectuating such assignment or subletting and such other information as
Landlord may reasonably request. Landlord shall have a period of ten (10)
business days following receipt of such notice and the required information
within which to do one of the following: (i) consent to such requested
assignment or subletting subject to Tenant's compliance with the conditions set
forth in Paragraph 7.4 below, or (ii) refuse to so consent to such requested
assignment or subletting, provided that such consent shall not be unreasonably
refused, or (iii) terminate this Lease as to the entire portion (approximately
half) of the floor on the side of the Building elevator bank on which the
subject portion of the Leased Premises is located, or, at Landlord's sole
option, as to only such portion of the Leased Premises as is the subject of the
proposed assignment or subletting. Notwithstanding the foregoing, Landlord shall
not have the right to elect option (iii) above with respect to subleases which
both (A) are for terms (including extension options) of not more than three (3)
years and (B) expire on or prior to five (5) years after the Lease Commencement
Date. During such ten (10) business day period, Tenant covenants and agrees to
supply to Landlord, upon request, all necessary or relevant information which
Landlord may reasonably request respecting such proposed assignment or
subletting and/or the proposed assignee or sublessee. In the event of an
election by Landlord under clause (iii) above, Tenant shall have the right to
withdraw such notice of intent to assign or sublet provided Tenant notifies
Landlord in writing of such withdrawal within five (5) business days after
receipt of Landlord's termination notice. In the event of an election by
Landlord under clause (iii) above, and absent Tenant's timely

                                       14.

<PAGE>

written withdrawal of such notice, Landlord shall have the right to enter into a
direct lease with the proposed assignee or sublessee without payment of any
consideration to Tenant. In addition, in the event Tenant desires to sublease
all or a portion of the Leased Premises, Landlord shall have the right to elect
to jointly market with Tenant the applicable portion (including all) of the
Leased Premises for subleasing and/or direct leasing, such joint marketing
election to be made, if at all, in writing and delivered to Tenant during the
thirty (30) day period described in the first sentence of this Paragraph 7.3.

7.4 Conditions To Landlord's Consent. If Landlord elects to consent, or shall
have been ordered to so consent by a court of competent jurisdiction, to such
requested assignment or subletting, such consent shall be expressly conditioned
upon the occurrence of each of the conditions below set forth, and any purported
assignment or subletting made or ordered prior to the full and complete
satisfaction of each of the following conditions shall be void and, at the
election of Landlord, which election may be exercised at any time following such
a purported assignment or subletting but prior to the satisfaction of each of
the stated conditions, shall constitute a material default by Tenant under this
Lease until cured by satisfying in full each such condition by the assignee or
sublessee. The conditions are as follows:

        (a) Landlord having approved in form and substance the assignment or
sublease agreement and any ancillary documents, which approval shall not be
unreasonably withheld by Landlord if the requirements of this Article 7 are
otherwise complied with.

        (b) Each such sublessee or assignee having agreed, in writing
satisfactory to Landlord and its counsel and for the benefit of Landlord, to
assume, to be bound by, and to perform the obligations of this Lease to be
performed by Tenant which relate to space being subleased.

        (c) Tenant having fully and completely performed all of its obligations
under the terms of this Lease through and including the date of such assignment
or subletting.

        (d) Tenant having reimbursed to Landlord all reasonable costs and
reasonable attorneys' fees incurred by Landlord in conjunction with the
processing and documentation of any such requested subletting or assignment.

        (e) Tenant having delivered to Landlord a complete and fully-executed
duplicate original of such sublease agreement or assignment agreement (as
applicable) and all related agreements.

        (f) Tenant having paid, or having agreed in writing to pay as to future
payments, to Landlord fifty percent (50%) of all assignment consideration or
excess rentals to be paid to Tenant or to any other on Tenant's behalf or for
Tenant's benefit for such assignment or subletting as follows:

               (i)   If Tenant assigns its interest under this Lease and if all
or a portion of the consideration for such assignment is to be paid by the
assignee at the time of the assignment, that Tenant shall have paid to Landlord
and Landlord shall have received an amount equal to fifty percent (50%) of the
assignment consideration so paid or to be paid (whichever is the greater) at the
time of the assignment by the assignee; or

               (ii)  If Tenant assigns its interest under this Lease and if
Tenant is to receive all or a portion of the consideration for such assignment
in future installments, that Tenant and Tenant's assignee shall have entered
into a written agreement with and for the benefit of Landlord satisfactory to
Landlord and its counsel whereby Tenant and Tenant's assignee jointly agree to
pay to Landlord an amount equal to fifty percent (50%) of all such future
assignment consideration installments to be paid by such assignee as and when
such assignment consideration is so paid.

               (iii) If Tenant subleases the Leased Premises, that Tenant and
Tenant's sublessee shall have entered into a written agreement with and for the
benefit of Landlord satisfactory to Landlord and its counsel whereby Tenant and
Tenant's sublessee jointly agree to pay to Landlord fifty percent (50%) of all
excess rentals to be paid by such sublessee as and when such excess rentals are
so paid.

7.5 Assignment Consideration And Excess Rentals Defined. For purposes of this
Article, including any amendment to this Article by way of addendum or other
writing, the term "assignment consideration" shall mean all consideration to be
paid by the assignee to Tenant or to any other party on Tenant's behalf or for
Tenant's benefit as consideration for such assignment, without deduction for any
commissions paid by Tenant or any other costs or expenses (including, without
limitation, tenant improvements, capital improvements, building upgrades, permit
fees, attorneys' fees, and other consultants' fees) incurred by Tenant in
connection with such assignment (provided that the cost of third party, market
rate brokerage commissions and improvements which are generic (and not
specialized) in nature and are generally reusable by other likely tenants of the
Leased Premises in Landlord's reasonable opinion, may be deducted if the
assignment is to an unaffiliated third party), and the term "excess rentals"
shall mean all consideration to be paid by the sublessee to Tenant or to any
other party on Tenant's behalf or for Tenant's benefit for the sublease of all
or any portion of the Leased Premises in excess of the rent due to Landlord
under the terms of this Lease for the portion so subleased for the same period,
without deduction for any commissions paid by Tenant or any other costs or
expenses (including, without limitation, tenant improvements, capital
improvements, building upgrades, permit fees, attorneys' fees, and other
consultants' fees) incurred by Tenant in connection with such sublease (provided
that the cost of third party, market rate brokerage commissions and improvements
which are generic (and not specialized) in nature and are generally reusable by
other likely tenants of the Leased Premises in Landlord's reasonable opinion,
may be deducted if the sublease is to an unaffiliated third party),. Tenant
agrees that the portion of any assignment consideration and/or excess rentals
arising from any assignment or subletting by Tenant which is to be paid to
Landlord pursuant to this Article now is and shall then be the property of
Landlord and not the property of Tenant.

                                       15.

7.6 Payments. All payments required by this Article to be made to Landlord shall
be made in cash in full as and when they become due. At the time Tenant,
Tenant's assignee or sublessee makes each such payment to Landlord, Tenant or
Tenant's assignee or sublessee, as the case may be, shall deliver to Landlord an
itemized statement in reasonable detail showing the method by which the amount
due Landlord was calculated and certified by the party making such payment as
true and correct.

7.7 Good Faith. The rights granted to Tenant by this Article are granted in
consideration of Tenant's express covenant that all pertinent allocations which
are made by Tenant between the rental value of the Leased Premises and the value
of any of Tenant's personal property which may be conveyed or leased (or
services provided) generally concurrently with and which may reasonably be
considered a part of the same transaction as the permitted assignment or
subletting shall be made fairly, honestly and in good faith. If Tenant shall
breach this covenant, Landlord may immediately declare Tenant to be in default
under the terms of this Lease and terminate this Lease and/or exercise any other
rights and remedies Landlord would have under the terms of this Lease in the
case of a material default by Tenant under this Lease.

7.8 Effect Of Landlord's Consent. No subletting or assignment, even with the
consent of Landlord, shall relieve Tenant of its personal and primary obligation
to pay rent and to perform all of the other obligations to be performed by
Tenant hereunder. Consent by Landlord to one or more assignments of Tenant's
interest in this Lease or to one or more sublettings of the Leased Premises
shall not be deemed to be a consent to any subsequent assignment or subletting.
No subtenant shall have any right to assign its sublease or to further sublet
any portion of the sublet premises or to permit any portion of the sublet
premises to be used or occupied by any other party. If Landlord shall have been
ordered by a court of competent jurisdiction to consent to a requested
assignment or subletting, or such an assignment or subletting shall have been
ordered by a court of competent jurisdiction over the objection of Landlord,
such assignment or subletting shall not be binding between the assignee (or
sublessee) and Landlord until such time as all conditions set forth in Paragraph
7.4 above have been fully satisfied (to the extent not then satisfied) by the
assignee or sublessee, including, without limitation, the payment to Landlord of
all agreed assignment considerations and/or excess rentals then due Landlord.

Landlord's active negligence, willful misconduct, or Landlord's failure to
perform an obligation expressly undertaken pursuant to this Lease after a
reasonable period of time shall have lapsed following receipt of written notice
from Tenant to so perform such obligation.

8.2 Tenant's Indemnification Of Landlord. Tenant shall defend with competent
counsel satisfactory to Landlord any claims made or legal actions filed or
threatened against Landlord with respect to the violation of any Law, or the
death, bodily injury, personal injury, property damage, or any other damages
suffered by any third party or Landlord occurring within the Leased Premises or
resulting from Tenant's use or occupancy of the Leased Premises, the Building or
the Outside Areas, or resulting from Tenant's activities in or about the Leased
Premises, the Building, the Outside Areas or the Property, and Tenant shall
indemnify and hold Landlord, Landlord's partners, principals, members,
employees, agents and contractors harmless from any loss liability, penalties,
or expense whatsoever (including any loss attributable to vacant space which
otherwise would have been leased, but for such activities) resulting therefrom,
except to the extent proximately caused by the active negligence or willful
misconduct of Landlord. This indemnity agreement shall survive the expiration or
sooner termination of this Lease.

                                    ARTICLE 9

<PAGE>

Tenant's activities in or about the Leased Premises or the Property, with
coverage in an amount equal to Tenant's Required Liability Coverage (as set
forth in Article 1), which insurance shall contain "blanket contractual

               (iv)  DELETED;

               (v)   Product liability insurance (including, without limitation,
if food and/or beverages are distributed, sold and/or consumed within the Leased
Premises, to the extent obtainable, coverage for liability arising out of the
distribution, sale, use or consumption of food and/or beverages (including
alcoholic beverages, if applicable) at the Leased Premises for not less than
Tenant's Required Liability Coverage (as set forth in Article 1);

               (vi)  Workers' compensation insurance (statutory coverage) with
employer's liability in amounts not less than $1,000,000 insurance sufficient to

like undertaken by Tenant, course of construction, commercial general liability,
automobile liability and workers' compensation (to be carried by Tenant's
contractor), in an amount and with coverage reasonably satisfactory to Landlord.

        (b) Each policy of liability insurance required to be carried by Tenant
pursuant to this paragraph or actually carried by Tenant with respect to the
Leased Premises or the Property: (i) shall, except with respect to insurance
required by subparagraph (a)(vii) above, name Landlord, and such others as are
designated by Landlord, as additional insureds; (ii) shall be primary insurance
providing that the insurer shall be liable for the full amount of the loss, up

not be subject to cancellation, lapse or change except after at least thirty
(30) days prior written notice to Landlord and (ii) shall contain a waiver
and/or a permission to waive by the insurer of any right of subrogation against
Landlord, its partners, principals, members, officers, employees, agents and
contractors, which might arise by reason of any payment under such policy or by
reason of any act or omission of Landlord, its partners, principals, members,
officers, employees, agents and contractors.

        (c) Prior to the time Tenant or any of its contractors enters the Leased
Premises, Tenant shall deliver to Landlord, with respect to each policy of
insurance required to be carried by Tenant pursuant to this Article, a copy of
such policy (appropriately authenticated by the insurer as having been issued,
premium paid) or a certificate of the insurer certifying in form satisfactory to
Landlord that a policy has been issued, premium paid, providing the coverage
required by this Paragraph and containing the provisions specified herein. With
respect to each renewal or replacement of any such insurance, the requirements
of this Paragraph must be complied with not less than thirty days prior to the
expiration or cancellation of the policies being renewed or replaced. Landlord
may, at any time and from time to time, inspect and/or copy any and all
insurance policies required to be carried by Tenant pursuant to this Article. If
Landlord's Lender, insurance broker, advisor or counsel reasonably determines at
any time that the amount of coverage set forth in Paragraph 9.1(a) for any
policy of insurance Tenant is required to carry pursuant to this Article is not
adequate, then Tenant shall increase the amount of coverage for such insurance
to such greater amount as Landlord's Lender, insurance broker, advisor or
counsel reasonably deems adequate.

9.2 Landlord's Insurance. With respect to insurance maintained by Landlord:

        (a) Landlord shall maintain, as the minimum coverage required of it by
this Lease, fire and property damage insurance in so-called special form
coverage insuring Landlord (and such others as Landlord may designate) against
loss from physical damage to the Building with coverage of not less than one
hundred percent (100%) of the full actual replacement cost thereof and against
loss of rents for a period of not less than six months. Such fire and property
damage insurance, at Landlord's election but without any requirements on
Landlord's behalf to do so, (i) may be written in so-called "all risk" form,
excluding only those perils commonly excluded from such coverage by Landlord's
then property damage insurer; (ii) may provide coverage for physical damage to
the improvements so insured for up to the entire full actual replacement cost
thereof; (iii) may be endorsed to cover loss or damage caused by any additional
perils against which Landlord may elect to insure, including earthquake and/or
flood; and/or (iv) may provide coverage for loss of rents for a period of up to
twelve months. Landlord shall not be required to cause such insurance to cover
any of Tenant's personal property, inventory, and trade fixtures, or any
modifications, alterations or improvements made or constructed by Tenant to or
within the Leased Premises. Landlord shall use commercially reasonable efforts
to obtain such insurance at competitive rates.

                                       17.

<PAGE>

        (b) Landlord shall maintain commercial general liability insurance
insuring Landlord (and such others as are designated by Landlord) against
liability for personal injury, bodily injury, death, and damage to property
occurring in, on or about, or resulting from the use or occupancy of the
Property, or any portion thereof, with combined single limit coverage of at
least Ten Million Dollars ($10,000,000). Landlord may carry such greater
coverage as Landlord or Landlord's Lender, insurance broker, advisor or counsel
may from time to time determine is reasonably necessary for the adequate
protection of Landlord and the Property.

        (c) Landlord may maintain any other insurance which in the opinion of
its insurance broker, advisor or legal counsel is prudent in carry under the
given circumstances, provided such insurance is commonly carried by owners of
property similarly situated and operating under similar circumstances.

9.3  Mutual Waiver Of Subrogation. Landlord hereby releases Tenant, and Tenant
hereby releases Landlord and its respective partners, principals, members,
officers, agents, employees and servants, from any and all liability for loss,
damage or injury to the property of the other in or about the Leased Premises or
the Property which is caused by or results from a peril or event or happening
which is covered by insurance actually carried and in force at the time of the
loss by the party sustaining such loss; provided, however, that such waiver
shall be effective only to the extent permitted by the insurance covering such
loss and to the extent such insurance is not prejudiced thereby.

                                   ARTICLE 10

                            DAMAGE TO LEASED PREMISES

10.1 Landlord's Duty To Restore. If the Leased Premises, the Building or the
Outside Area are damaged by any peril after the Effective Date of this Lease,
Landlord shall restore the same, as and when required by this paragraph, unless
this Lease is terminated by Landlord pursuant to Paragraph 10.3 or by Tenant
pursuant to Paragraph 10.4. If this Lease is not so terminated, then upon the
issuance of all necessary governmental permits, Landlord shall commence and
diligently prosecute to completion the restoration of the Leased Premises, the
Building or the Outside Area, as the case may be, to the extent then allowed by
law, to substantially the same condition in which it existed as of the Lease
Commencement Date. Landlord's obligation to restore shall be limited to the
improvements constructed by Landlord. Landlord shall have no obligation to
restore any alterations, modifications or improvements made by Tenant to the
Leased Premises or any of Tenant's personal property, inventory or trade
fixtures. Upon completion of the restoration by Landlord, Tenant shall forthwith
replace or fully repair all of Tenant's personal property, inventory, trade
fixtures and other improvements constructed by Tenant to like or similar
conditions as existed at the time immediately prior to such damage or
destruction.

10.2 Insurance Proceeds. All insurance proceeds available from the fire and
property damage insurance carried by Landlord shall be paid to and become the
property of Landlord. If this Lease is terminated pursuant to either Paragraph
10.3 or 10.4, all insurance proceeds available from insurance carried by Tenant
which cover loss of property that is Landlord's property or would become
Landlord's property on termination of this Lease shall be paid to and become the
property of Landlord, and the remainder of such proceeds shall be paid to and
become the property of Tenant. If this Lease is not terminated pursuant to
either Paragraph 10.3 or 10.4, all insurance proceeds available from insurance
carried by Tenant which cover loss to property that is Landlord's property shall
be paid to and become the property of Landlord, and all proceeds available from
such insurance which cover loss to property which would only become the property
of Landlord upon the termination of this Lease shall be paid to and remain the
property of Tenant. The determination of Landlord's property and Tenant's
property shall be made pursuant to Paragraph 6.2.

10.3 Landlord's Right To Terminate. Landlord shall have the option to terminate
this Lease in the event any of the following occurs, which option may be
exercised only by delivery to Tenant of a written notice of election to
terminate within thirty days after the date of such damage or destruction:

        (a) The Building is damaged by any peril covered by valid and
collectible insurance actually carried by Landlord and in force at the time of
such damage or destruction (an "insured peril") to such an extent that the
estimated cost to restore the Building exceeds the lesser of (i) the insurance
proceeds available from insurance actually carried by Landlord, or (ii) fifty
percent of the then actual replacement cost thereof;

        (b) The Building is damaged by an uninsured peril, which peril Landlord
was not required to insure against pursuant to the provisions of Article 9 of
this Lease.

        (c) The Building is damaged by any peril and, because of the laws then
in force, the Building (i) cannot be restored at reasonable cost or (ii) if
restored, cannot be used for the same use being made thereof before such damage.

10.4 Tenant's Right To Terminate. If the Leased Premises, the Building or the
Outside Area are damaged by any peril and Landlord does not elect to terminate
this Lease or is not entitled to terminate this Lease pursuant to this Article,
then as soon as reasonably practicable, Landlord shall furnish Tenant with the
written opinion of Landlord's architect or construction consultant as to when
the restoration work required of Landlord may be complete. Tenant shall have the
option to terminate this Lease in the event any of the following occurs, which
option may be exercised only by delivery to Landlord of a written notice of
election to terminate within ten business days after Tenant receives from
Landlord the estimate of the time needed to complete such restoration:

        (a) If the time estimated to substantially complete the restoration
exceeds nine months from and after the date the architect's or construction
consultant's written opinion is delivered; or

                                       18.

<PAGE>

        (b) If the damage occurred within twelve months of the last day of the
Lease Term and the time estimated to substantially complete the restoration
exceeds ninety days from and after the date such restoration is commenced.

10.5 Tenant's Waiver. Landlord and Tenant agree that the provisions of Paragraph
10.4 above, captioned "Tenant's Right To Terminate", are intended to supersede
and replace the provisions contained in California Civil Code, Section 1932,
Subdivision 2, and California Civil Code, Section 1934, and accordingly, Tenant
hereby waives the provisions of such Civil Code Sections and the provisions of
any successor Civil Code Sections or similar laws hereinafter enacted.

10.6 Abatement Of Rent. In the event of damage to the Leased Premises which does
not result in the termination of this Lease, the Base Monthly Rent (and any
Additional Rent) shall be temporarily abated during the period of restoration in
proportion in the degree to which Tenant's use of the Leased Premises is
impaired by such damage.

                                   ARTICLE 11

                                  CONDEMNATION

11.1 Tenant's Right To Terminate. Except as otherwise provided in Paragraph 11.4
below regarding temporary takings, Tenant shall have the option to terminate
this Lease if, as a result of any taking, (i) all of the Leased Premises is
taken, or (ii) twenty-five percent (25%) or more of the Leased Premises is taken
and the part of the Leased Premises that remains cannot, within a reasonable
period of time, be made reasonably suitable for the continued operation of
Tenant's business. Tenant must exercise such option within a reasonable period
of time, to be effective on the later to occur of (i) the date that possession
of that portion of the Leased Premises that is condemned is taken by the
condemnor or (ii) the date Tenant vacated the Leased Premises.

11.2 Landlord's Right To Terminate. Except as otherwise provided in Paragraph
11.4 below regarding temporary takings, Landlord shall have the option to
terminate this Lease if, as a result of any taking, (i) all of the Leased
Premises is taken, (ii) twenty-five percent (25%) or more of the Leased Premises
is taken and the part of the Leased Premises that remains cannot, within a
reasonable period of time, be made reasonably suitable for the continued
operation of Tenant's business, or (iii) because of the laws then in force, the
Leased Premises may not be used for the same use being made before such taking,
whether or not restored as required by Paragraph 11.3 below. Any such option to
terminate by Landlord must be exercised within a reasonable period of time, to
be effective as of the date possession is taken by the condemnor.

11.3 Restoration. If any part of the Leased Premises or the Building is taken
and this Lease is not terminated, then Landlord shall, to the extent not
prohibited by laws then in force, repair any damage occasioned thereby to the
remainder thereof to a condition reasonably suitable for Tenant's continued
operations and otherwise, to the extent practicable, in the manner and to the
extent provided in Paragraph 10.1.

11.4 Temporary Taking. If a portion of the Leased Premises is temporarily taken
for a period of one year or less and such period does not extend beyond the
Lease Expiration Date, this Lease shall remain in effect. If any portion of the
Leased Premises is temporarily taken for a period which exceeds one year or
which extends beyond the Lease Expiration Date, then the rights of Landlord and
Tenant shall be determined in accordance with Paragraphs 11.1 and 11.2 above.

11.5 Division Of Condemnation Award. Any award made for any taking of the
Property, the Building, or the Leased Premises, or any portion thereof, shall
belong to and be paid to Landlord, and Tenant hereby assigns to Landlord all of
its right, title and interest in any such award; provided, however, that Tenant
shall be entitled to receive any portion of the award that is made specifically
(i) for the taking of personal property, inventory or trade fixtures belonging
to Tenant, (ii) for the interruption of Tenant's business or its moving costs,
or (iii) for the value of any leasehold improvements installed and paid for by
Tenant. In the event of a temporary taking where this Lease is not terminated,
because there will be no abatement of rent, Tenant shall be entitled to all of
the award for said taking. The rights of Landlord and Tenant regarding any
condemnation shall be determined as provided in this Article, and each party
hereby waives the provisions of Section 1265.130 of the California Code of Civil
Procedure, and the provisions of any similar law hereinafter enacted, allowing
either party to petition the Supreme Court to terminate this Lease and/or
otherwise allocate condemnation awards between Landlord and Tenant in the event
of a taking of the Leased Premises.

11.6 Abatement Of Rent. In the event of a taking of the Leased Premises which
does not result in a termination of this Lease (other than a temporary taking),
then, as of the date possession is taken by the condemning authority, the Base
Monthly Rent shall be reduced in the same proportion that the area of that part
of the Leased Premises so taken (less any addition to the area of the Leased
Premises by reason of any reconstruction) bears to the area of the Leased
Premises immediately prior to such taking.

11.7 Taking Defined. The term "taking" or "taken" as used in this Article 11
shall mean any transfer or conveyance of all or any portion of the Property to a
public or quasi-public agency or other entity having the power of eminent domain
pursuant to or as a result of the exercise of such power by such an agency,
including any inverse condemnation and/or any sale or transfer by Landlord of
all or any portion of the Property to such an agency under threat of
condemnation or the exercise of such power.

shall not be required to provide any further notices to Tenant. Each such notice
shall be concurrent with, and not in addition to, any notice required by
applicable Laws; or

within the shorter of (i) any specific time period expressly provided under this
Lease for the performance of such term, covenant or condition, or (ii) thirty
(30) days after written notice from Landlord to Tenant specifying the nature of
such failure and requesting Tenant to perform same; provided that, if such
default is curable but longer than thirty (30) days is reasonably required in
order to perform such obligations and Tenant has substantially commenced said
performance within said thirty (30) day period, Tenant shall have such longer
period as may be reasonably required to complete said performance; or

        (d) Tenant shall have sublet the Leased Premises or assigned or
encumbered its interest in this Lease in violation of the provisions contained
in Article 7, whether voluntarily or by operation of law; or

        (e) Tenant shall have abandoned the Leased Premises; or

        (f) Tenant or any Guarantor of this Lease shall have permitted or

essential to the conduct of Tenant's (or such Guarantor's) business, and Tenant

within thirty days thereafter, or prior to sale pursuant to such sequestration,
attachment or levy, whichever is earlier; or

        (g) Tenant or any Guarantor of this Lease shall have made a general

order for relief, appointment of a trustee, or condemnation or a reorganization
plan under the bankruptcy laws of the United States; (ii) approves as properly
filed a petition seeking liquidation or reorganization under said bankruptcy
laws or any other debtor's relief law or similar statute of the United States or
any state thereof; or (iii) otherwise directs the winding up or liquidation of
Tenant; provided, however, if any decree or order was entered without Tenant's
consent or over Tenant's objection, Landlord may not terminate this Lease
pursuant to this Subparagraph if such decree or order is rescinded or reversed
within thirty days after its original entry; or

        (i) Tenant or any Guarantor of this Lease shall have availed itself of
the protection of any debtor's relief law, moratorium law or other similar law
which does not require the prior entry of a decree or order.

        (j) Tenant shall be in default of its obligations under any lease
between Landlord and Tenant.

12.2 Landlord's Remedies. In the event of any default by Tenant, and without
limiting Landlord's right to indemnification as provided in Article 8.2,
Landlord shall have the following remedies, in addition to all other rights and
remedies provided by law or otherwise provided in this Lease, to which Landlord
may resort cumulatively, or in the alternative:

        (a) Landlord may, at Landlord's election, keep this Lease in effect and
enforce, by an action at law or in equity, all of its rights and remedies under
this Lease including, without limitation, (i) the right to recover the rent and
other sums as they become due by appropriate legal action, (ii) the right to
make payments required by Tenant, or perform Tenant's obligations and be
reimbursed by Tenant for the cost thereof with interest at the then maximum rate
of interest not prohibited by law from the date the sum is paid by Landlord
until Landlord is reimbursed by Tenant, and (iii) the remedies of injunctive
relief and specific performance to prevent Tenant from violating the terms of
this Lease and/or to compel Tenant to perform its obligations under this Lease,
as the case may be.

        (b) Landlord may, at Landlord's election, terminate this Lease by giving
Tenant written notice of termination, in which event this Lease shall terminate
on the date set forth for termination in such notice, in which event Tenant
shall immediately surrender the Leased Premises to Landlord, and if Tenant fails
to do so, Landlord may, without prejudice to any other remedy which it may have
for possession or arrearages in rent, enter upon and take possession of the
Leased Premises and expel or remove Tenant and any other person who may be
occupying the Leased Premises or any part thereof, without being liable for
prosecution or any claim or damages therefor. Any

termination under this subparagraph shall not relieve Tenant from its
obligation to pay to Landlord all Base Monthly Rent and Additional Rent then or
thereafter due, or any other sums due or thereafter accruing to Landlord, or
from any claim against Tenant for damages previously accrued or then or
thereafter accruing. In no event shall any one or more of the following actions
by Landlord, in the absence of a written election by Landlord to terminate this
Lease constitute a termination of this Lease:

               (i)   Appointment of a receiver or keeper in order to protect
Landlord's interest hereunder;

               (ii)  Consent to any subletting of the Leased Premises or
assignment of this Lease by Tenant, whether pursuant to the provisions hereof or
otherwise; or

               (iii) Any action taken by Landlord or its partners, principals,
members, officers, agents, employees, or servants, which is intended to mitigate
the adverse effects of any breach of this Lease by Tenant, including, without
limitation, any action taken to maintain and preserve the Leased Premises on any
action taken to relet the Leased Premises or any portion thereof for the account
at Tenant and in the name of Tenant.

     (c)   In the event Tenant breaches this Lease and abandons the Leased
Premises, Landlord may terminate this Lease, but this Lease shall not terminate
unless Landlord gives Tenant written notice of termination. If Landlord does not
terminate this Lease by giving written notice of termination, Landlord may
enforce all its rights and remedies under this Lease, including the right and
remedies provided by California Civil Code Section 1951.4 ("lessor may continue
lease in effect after lessee's breach and abandonment and recover rent as it
becomes due, if lessee has right to sublet or assign, subject only to reasonable
limitations"), as in effect on the Effective Date of this Lease.

     (d)   In the event Landlord terminates this Lease, Landlord shall be
entitled, at Landlord's election, to the rights and remedies provided in
California Civil Code Section 1951.2, as in effect on the Effective Date of this
Lease. For purposes of computing damages pursuant to Section 1951.2, an interest
rate equal to the maximum rate of interest then not prohibited by law shall be
used where permitted. Such damages shall include, without limitation:

               (i)   The worth at the time of the award of the unpaid rent
which had been earned at the time of termination;

               (ii)  The worth at the time of award of the amount by which the
unpaid rent for the balance of the term after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided,
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco, at the time of award plus one percent; and

               (iii) Any other amount necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease, or which in the ordinary course of things would be likely to
result therefrom, including without limitation, the following: (i) expenses for
cleaning, repairing or restoring the Leased Premises, (ii) expenses for
altering, remodeling or otherwise improving the Leased Premises for the purpose
of reletting, including removal of existing leasehold improvements and/or
installation of additional leasehold improvements (regardless of how the same is
funded, including reduction of rent, a direct payment or allowance to a new
tenant, or otherwise), (iii) broker's fees allocable to the remainder of the
term of this Lease, advertising costs and other expenses of reletting the Leased
Premises; (iv) costs of carrying and maintaining the Leased Premises, such as
taxes, insurance premiums, utility charges and security precautions, (v)
expenses incurred in removing, disposing of and/or storing any of Tenant's
personal property, inventory or trade fixtures remaining therein; (vi)
reasonable attorney's fees, expert witness fees, court costs and other
reasonable expenses incurred by Landlord (but not limited to taxable costs) in
retaking possession of the Leased Premises, establishing damages hereunder, and
releasing the Leased Premises; and (vii) any other expenses, costs or damages
otherwise incurred or suffered as a result of Tenant's default.

12.3 Landlord's Default And Tenant's Remedies. In the event Landlord fails to
perform its obligations under this Lease, Landlord shall nevertheless not be in
default under the terms of this Lease until such time as Tenant shall have first
given Landlord written notice specifying the nature of such failure to perform
its obligations, and then only after Landlord shall have had thirty (30) days
following its receipt of such notice within which to perform such obligations;
provided that, if longer than thirty (30) days is reasonably required in order
to perform such obligations and Landlord has reasonably commenced said
performance within said thirty (30) day period, Landlord shall have such longer
period. Notwithstanding the foregoing, Landlord agrees to act with reasonable
diligence in making repairs it is required to make to the Building or otherwise
in performing its obligations hereunder. In the event of Landlord's default as
above set forth, then, and only then, Tenant may then proceed in equity or at
law to compel Landlord to perform its obligations and/or to recover damages
proximately caused by such failure to perform (except as and to the extent
Tenant has waived its right to damages as provided in this Lease).

12.4 Limitation Of Tenant's Recourse. Tenant's sole recourse against Landlord
shall be to Landlord's interest in the Building and the Outside Areas. If
Landlord is a corporation, trust, partnership, joint venture, limited liability
company, unincorporated association, or other form of business entity, Tenant
agrees that (i) the obligations of Landlord under this Lease shall not
constitute personal obligations of the officers, directors, trustees, partners,
joint venturers, members, owners, stockholders, or other principals of such
business entity, and (ii) Tenant shall have recourse only to the interest of
such corporation, trust, partnership, joint venture, limited liability company,
unincorporated association, or other form of business entity in the Building and
the Outside Areas for the satisfaction of such obligations and not against the
assets of such officers, directors, trustees, partners, joint

                                       21.

<PAGE>

venturers, members, owners, stockholders or principals. Additionally, if
Landlord is a partnership or limited liability company, then Tenant covenants
and agrees:

     (a) No partner or member of Landlord shall be sued or named as a party in
any suit or action brought by Tenant with respect to any alleged breach of this
Lease (except to the extent necessary to secure jurisdiction over the
partnership and then only for that sole purpose);

     (b) No service of process shall be made against any partner or member of
Landlord except for the sole purpose of securing jurisdiction over the
partnership; and

     (c) No writ of execution will ever be levied against the assets of any
partner or member of Landlord other than to the extent of his or her interest in
the assets of the partnership or limited liability company constituting
Landlord.

Tenant further agrees that each of the foregoing covenants and agreements shall
be enforceable by Landlord and by any partner or member of Landlord and shall be
applicable to any actual or alleged misrepresentation or nondisclosure made
regarding this Lease or the Leased Premises or any actual or alleged failure,
default or breach of any covenant or agreement either expressly or implicitly
contained in this Lease or imposed by statute or at common law.

12.5 Tenant's Waiver. Landlord and Tenant agree that the provisions of Paragraph
12.3 above are intended to supersede and replace the provisions of California
Civil Code Sections 1932(1), 1941 and 1942, and accordingly, Tenant hereby
waives the provisions of California Civil Code Sections 1932(1), 1941 and 1942
and/or any similar or successor law regarding Tenant's right to terminate this
Lease or to make repairs and deduct the expenses of such repairs from the rent
due under this Lease.

                                   ARTICLE 13

                               GENERAL PROVISIONS

13.1 Taxes On Tenant's Property. Tenant shall pay before delinquency any and all
taxes, assessments, license fees, use fees, permit fees and public charges of
whatever nature or description levied, assessed or imposed against Tenant or
Landlord by a governmental agency arising out of, caused by reason of or based
upon Tenant's estate in this Lease, Tenant's ownership of property, improvements
made by Tenant to the Leased Premises or the Outside Areas, improvements made by
Landlord for Tenant's use within the Leased Premises or the Outside Areas,
Tenant's use (or estimated use) of public facilities or services or Tenant's
consumption (or estimated consumption) of public utilities, energy, water or
other resources (collectively, "Tenant's Interest"). Upon demand by Landlord,
Tenant shall furnish Landlord with satisfactory evidence of these payments. If
any such taxes, assessments, fees or public charges are levied against Landlord,
Landlord's property, the Building or the Property, or if the assessed value of
the Building or the Property is increased by the inclusion therein of a value
placed upon Tenant's Interest, regardless of the validity thereof, Landlord
shall have the right to require Tenant to pay such taxes, and if not paid and
satisfactory evidence of payment delivered to Landlord at least ten days prior
to delinquency, then Landlord shall have the right to pay such taxes on Tenant's
behalf and to invoice Tenant for the same, in either case whether before or
after the expiration or earlier termination of the Lease Term. Tenant shall, no
later than the later of (a) ten (10) days prior to the due date, and (b) fifteen
(15) days after delivery to Tenant, pay to Landlord, as Additional Rent, the
amount set forth in such invoice. Failure by Tenant to pay the amount so
invoiced within such time period shall be conclusively deemed a default by
Tenant under this Lease. Tenant shall have the right to bring suit in any court
of competent jurisdiction to recover from the taxing authority the amount of any
such taxes, assessments, fees or public charges so paid.

13.2 Holding Over. This Lease shall terminate without further notice on the
Lease Expiration Date (as set forth in Article 1). Any holding over by Tenant
after expiration of the Lease Term shall neither constitute a renewal nor
extension of this Lease nor give Tenant any rights in or to the Leased Premises
except as expressly provided in this Paragraph. Any such holding over to which
Landlord has consented shall be construed to be a tenancy from month to month,
on the same terms and conditions herein specified insofar as applicable, except
that the Base Monthly Rent shall be increased to an amount equal to one hundred
fifty percent (150%) of the Base Monthly Rent payable during the last full month
immediately preceding such holding over. Tenant acknowledges that if Tenant
holds over without Landlord's consent, such holding over may compromise or
otherwise affect Landlord's ability to enter into new leases with prospective
tenants regarding the Leased Premises. Therefore, if Tenant fails to surrender
the Leased Premises upon the expiration or termination of this Lease, in
addition to any other liabilities to Landlord accruing therefrom, Tenant shall
protect, defend, indemnify and hold Landlord harmless from and against all
claims resulting from such failure, including, without limiting the foregoing,
any claims made by any succeeding tenant founded upon such failure to surrender,
and any losses suffered by Landlord, including lost profits, resulting from such
failure to surrender.

13.3 Subordination To Mortgages. This Lease is subject to and subordinate to all
ground leases, mortgages and deeds of trust which affect the Building or the
Property and which are of public record as of the Effective Date of this Lease,
and to all renewals, modifications, consolidations, replacements and extensions
thereof. However, if the lessor under any such ground lease or any lender
holding any such mortgage or deed of trust shall advise Landlord that it desires
or requires this Lease to be made prior and superior thereto, then, upon written
request of Landlord to Tenant, Tenant shall promptly execute, acknowledge and
deliver any and all customary or reasonable documents or instruments which
Landlord and such lessor or lender deems necessary or desirable to make this
Lease prior thereto. Tenant hereby consents to Landlord's ground leasing the
land underlying the Building or the Property and/or encumbering the Building or
the Property as security for future loans on such terms as Landlord shall
desire, all of

                                       22.

<PAGE>

which future ground leases, mortgages or deeds of trust shall be subject to
and subordinate to this Lease. However, if any lessor under any such future
ground lease or any lender holding such future mortgage or deed of trust shall
desire or require that this Lease be made subject to and subordinate to such
future ground lease, mortgage or deed of trust, then Tenant agrees, within ten
days after Landlord's written request therefor, to execute, acknowledge and
deliver to Landlord any and all documents or instruments requested by Landlord
or by such lessor or lender as may be necessary or proper to assure the
subordination of this Lease to such future ground lease, mortgage or deed of
trust, but only if such lessor or lender agrees not to disturb Tenant's quiet
possession of the Leased Premises so long as Tenant is not in default under this
Lease (as evidenced by a then customary and reasonable subordination and
non-disturbance agreement). If Landlord assigns the Lease as security for a
loan, Tenant agrees to execute such documents as are reasonably requested by the
lender and to provide reasonable provisions in the Lease protecting such
lender's security interest which are customarily required by institutional
lenders making loans secured by a deed of trust.

13.4  Tenant's Attornment Upon Foreclosure. Tenant shall, upon request, attorn
(i) to any purchaser of the Building or the Property at any foreclosure sale or
private sale conducted pursuant to any security instruments encumbering the
Building or the Property, (ii) to any grantee or transferee designated in any
deed given in lieu of foreclosure of any security interest encumbering the
Building or the Property, or (iii) to the lessor under an underlying ground
lease of the land underlying the Building or the Property, should such ground
lease be terminated; provided that such purchaser, grantee or lessor recognizes
Tenant's rights under this Lease.

13.5  Mortgagee Protection. In the event of any default on the part of Landlord,
Tenant will give notice by registered mail to any Lender or lessor under any
underlying ground lease who shall have requested, in writing, to Tenant that it
be provided with such notice, and Tenant shall offer such Lender or lessor a
reasonable opportunity to cure the default, including time to obtain possession
of the Leased Premises by power of sale or judicial foreclosure or other
appropriate legal proceedings if reasonably necessary to effect a cure.

13.6  Estoppel Certificate. Tenant will, following any request by Landlord,
promptly execute and deliver to Landlord an estoppel certificate in a form
reasonably requested by Landlord (including but not limited to the form attached
as Exhibit "F"), (i) certifying that this Lease is unmodified and in full force
and effect, or, if modified, stating the nature of such modification and
certifying that this Lease, as so modified, is in full force and effect, (ii)
stating the date to which the rent and other charges are paid in advance, if
any, (iii) acknowledging that there are not, to Tenant's knowledge, any uncured
defaults on the part of Landlord hereunder, or specifying such defaults if any
are claimed, and (iv) certifying such other information about this Lease as may
be reasonably requested by Landlord, its Lender or prospective lenders,
investors or purchasers of the Building or the Property. Tenant's failure to
execute and deliver such estoppel certificate within ten days after Landlord's
request therefor shall be a material default by Tenant under this Lease, and
Landlord shall have all of the rights and remedies available to Landlord as
Landlord would otherwise have in the case of any other material default by
Tenant, including the right to terminate this Lease and sue for damages
proximately caused thereby, it being agreed and understood by Tenant that
Tenant's failure to so deliver such estoppel certificate in a timely manner
could result in Landlord being unable to perform committed obligations to other
third parties which were made by Landlord in reliance upon this covenant of
Tenant. Landlord and Tenant intend that any statement delivered pursuant to this
paragraph may be relied upon by any Lender or purchaser or prospective Lender or
purchaser of the Building, the Property, or any interest in them.

13.7  Tenant's Financial Information. Tenant shall, within ten business days
after Landlord's request therefor, deliver to Landlord a copy of Tenant's (and
any guarantor's) current financial statements (including a balance sheet, income
statement and statement of cash flow, all prepared in accordance with generally
accepted accounting principles), a list of all of Tenant's creditors with
current contact information, and any such other information reasonably requested
by Landlord regarding Tenant's financial condition. Landlord shall be entitled
to disclose such financial statements or other information to its Lender, to any
present or prospective principal of or investor in Landlord, or to any
prospective Lender or purchaser of the Building, the Property, or any portion
thereof or interest therein. Any such financial statement or other information
which is marked "confidential" or "company secrets" (or is otherwise similarly
marked by Tenant) shall be confidential and shall not be disclosed by Landlord
to any third party except as specifically provided in this paragraph, unless the
same becomes a part of the public domain without the fault of Landlord.

13.8  Transfer By Landlord. Landlord and its successors in interest shall have
the right to transfer their interest in the Building, the Property, or any
portion thereof at any time and to any person or entity. In the event of any
such transfer, the Landlord originally named herein (and in the case of any
subsequent transfer, the transferor), from the date of such transfer, (i) shall
be automatically relieved, without any further act by any person or entity, of
all liability for the performance of the obligations of the Landlord hereunder
which may accrue after the date of such transfer and (ii) shall be relieved of
all liability for the performance of the obligations of the Landlord hereunder
which have accrued before the date of transfer if its transferee agrees to
assume and perform all such prior obligations of the Landlord hereunder. Tenant
shall attorn to any such transferee. After the date of any such transfer, the
term "Landlord" as used herein shall mean the transferee of such interest in the
Building or the Property.

13.9  Force Majeure. The obligations of each of the parties under this Lease
(other than the obligations to pay money) shall be temporarily excused if such
party is prevented or delayed in performing such obligations by reason of any
strikes, lockouts or labor disputes; government restrictions, regulations,
controls, action or inaction; civil commotion; or extraordinary weather, fire or
other acts of God.

13.10 Notices. Any notice required or permitted to be given under this Lease
shall be in writing and (i) personally delivered, (ii) sent by United States
mail, registered or certified mail, postage prepaid, return receipt requested,
(iii) sent by Federal Express or similar nationally recognized overnight courier
service, or (iv) transmitted by facsimile with a hard copy sent within one (1)
business day by any of the foregoing means, and in all cases

                                       23.

13.11 Attorneys' Fees. In the event any party shall bring any action,
arbitration proceeding or legal proceeding alleging a breach of any provision of
this Lease, to recover rent, to terminate this Lease, or to enforce, protect,
determine or establish any term or covenant of this Lease or rights or duties

from the non-prevailing party as a part of such action or proceeding, or in a
separate action for that purpose brought within one year from the determination
of such proceeding, reasonable attorneys' fees, expert witness fees, court costs
and other reasonable expenses incurred by the prevailing party.

13.12 Definitions. Any term that is given a special meaning by any provision in
this Lease shall, unless otherwise specifically stated, have such meaning
wherever used in this Lease or in any Addenda or amendment hereto. In addition
to the terms defined in Article 1, the following terms shall have the following
meanings:

      (a) Real Property Taxes. The term "Real Property Tax" or "Real Property
Taxes" shall each mean Tenant's Expense Share of the following (to the extent
applicable to any portion of the Lease Term, regardless of when the same are
imposed, assessed, levied, or otherwise charged): (i) all taxes, assessments,
levies and other charges of any kind or nature whatsoever, general and special,
foreseen and unforeseen (including all instruments of principal and interest
required to pay any general or special assessments for public improvements and
any increases resulting from reassessments caused by any change in ownership or
new construction), now or hereafter imposed by any governmental or
quasi-governmental authority or special district having the direct or indirect
power to tax or levy assessments, which are levied or assessed for whatever
reason against the Property or any portion thereof, or Landlord's interest
herein, or the fixtures, equipment and other property of Landlord that is an
integral part of the Property and located thereon, or Landlord's business of
owning, leasing or managing the Property or the gross receipts, income or
rentals from the Property, (ii) all charges, levies or fees imposed by any
governmental authority against Landlord by reason of or based upon the use of or
number of parking spaces within the Property, the amount of public services or
public utilities used or consumed (e.g. water, gas, electricity, sewage or waste
water disposal) at the Property, the number of persons employed by tenants of
the Property, the size (whether measured in area, volume, number of tenants or
whatever) or the value of the Property, or the type of use or uses conducted
within the Property, and all costs and fees (including attorneys' fees)
reasonably incurred by Landlord in contesting any Real Property Tax and in
negotiating with public authorities as to any Real Property Tax. If, at any time
during the Lease Term, the taxation or assessment of the Property prevailing as
of the Effective Date of this Lease shall be altered so that in lieu of or in
addition to any the Real Property Tax described above there shall be levied,
awarded or imposed (whether by reason of a change in the method of taxation or
assessment, creation of a new tax or charge, or any other cause) an alternate,
substitute, or additional use or charge (i) on the value, size, use or occupancy
of the Property or Landlord's interest therein or (ii) on or measured by the
gross receipts, income or rentals from the Property, or on Landlord's business
of owning, leasing or managing the Property or (iii) computed in any manner with
respect to the operation of the Property, then any such tax or charge, however
designated, shall be included within the meaning of the terms "Real Property
Tax" or "Real Property Taxes" for purposes of this Lease. If any Real Property
Tax is partly based upon property or rents unrelated to the Property, then only
that part of such Real Property Tax that is fairly allocable to the Property
shall be included within the meaning of the terms "Real Property Tax" or "Real
Property Taxes." Notwithstanding the foregoing, the terms "Real Property Tax" or
"Real Property

                                       24.

<PAGE>

Taxes" shall not include estate, inheritance, transfer, gift or franchise taxes
of Landlord or the federal or state income tax imposed on Landlord's income from
all sources.

     (b) Landlord's Insurance Costs.

         (i)  The term "Landlord's Insurance Costs" shall mean Tenant's Expense
Share of the following (to the extent applicable to any portion of the Lease
Term, regardless of when the same are incurred): the costs to Landlord to carry
and maintain the policies of fire and property damage insurance for the Building
and the Property and general liability and any other insurance required or
permitted to be carried by Landlord pursuant to Article 9, together with any
deductible amounts paid by Landlord upon the occurrence of any insured casualty
or loss. In the event in any year the Building is less than 95% occupied, the
Landlord's Insurance Costs shall be adjusted to reflect a 95% occupancy level.

         (ii) Notwithstanding the foregoing, and with respect to earthquake
insurance policies only, Tenant's Expense Share of the deductible amount under
such policy(ies) shall be limited on each occurrence to Tenant's Expense Share
of the deductible amount that would result if: (A) Landlord had insured the
Building and other insurable improvements for 100% of their replacement value
(subject to the deductible stated in the policy(ies)), (B) the deductible stated
in the policy(ies) does not exceed 15% of such replacement value, and (C) such
resulting amount were amortized using an interest rate equal to Wells Prime Plus
Two, over the useful life of the modifications, alterations or improvements
constructed with the deductible amount, and the monthly amortized amount of such
deductible amount as so amortized were considered a Property Maintenance Cost.

     (c) Property Maintenance Costs. The term "Property Maintenance Costs" shall
mean Tenant's Expense Share of all costs and expenses (except Landlord's
Insurance Costs and Real Property Taxes) paid or incurred by Landlord in
protecting, operating, maintaining, repairing and preserving the Property and
all parts thereof, including without limitation, (i) market rate professional
management fees (not to exceed 3% of gross rent), (ii) the amortizing portion of
any costs incurred by Landlord in the making of any modifications, alterations
or improvements required by any governmental authority as set forth in Article
6, which are so amortized during the Lease Term, and (iii) such other costs as
may be paid or incurred with respect to operating, maintaining, and preserving
the Property, such as repairing and resurfacing the exterior surfaces of the
Building (including roofs), repairing and resurfacing paved areas, repairing and
replacing structural parts of the Building, and repairing and replacing, when
necessary, electrical, plumbing, heating, ventilating and air conditioning
systems serving the Building, and common elements such as elevators, stair
wells, and lobbies. In the event in any year the Building is less than 95%
occupied, the Property Maintenance Costs shall be adjusted to reflect a 95%
occupancy level. To the extent any of the foregoing items described constitute
capital repairs or replacements under generally accepted accounting principles,
consistently applied, then only the amortizing portion of such capital repairs
or replacements shall constitute Property Maintenance Costs; such amortization
shall be over the useful life of the applicable repair or replacement, and shall
employ a per annum interest rate equal to Wells Prime Plus Two, and only the
amortizing portion of such cost shall be included in Additional Rent on a
monthly basis.

Notwithstanding the foregoing provisions of this Paragraph 13.12(c), the
following are specifically excluded from the definition of Property Maintenance
Costs and Tenant shall have no obligation to pay directly or reimburse Landlord
for all or any portion of the following except to the extent any of the
following are caused by the actions or inactions of Tenant, or result from the
failure of Tenant to comply with the terms of this Lease: (i) legal and auditing
fees (other than those fees reasonably incurred in connection with the
maintenance and operation of all or any portion the Building), leasing
commissions, advertising expenses, and other costs incurred in connection with
the original leasing of the Property or future re-leasing of any portion of the
Building; (ii) depreciation of the Building or any other improvements situated
within the Project; (iii) any items for which Landlord is actually reimbursed by
insurance or by direct reimbursement by Tenant or any other party; (iv) costs of
repairs or other work necessitated by fire, windstorm or other casualty
(excluding any deductibles) and/or costs of repair or other work necessitated by
the exercise of the right of eminent domain to the extent insurance proceeds or
a condemnation award, as applicable, is actually received by Landlord for such
purposes; (v) other than any interest charges for capital improvements referred
to in Paragraph 6.3 of this Lease, any interest or payments on any financing for
the Building, interest and penalties incurred as a result of Landlord's late
payment of any invoice (provided that Tenant pays Tenant's Expense Share of
Property Operating Expenses and Real Property Taxes to Landlord when due as set
forth herein), and any bad debt loss, rent loss or reserves for same; (vi)
overhead and profit increment paid to Landlord or to subsidiaries or affiliates
of Landlord for goods and/or services in the Project to the extent the same
exceeds the costs of such by unaffiliated third parties on a competitive basis;
or any costs included in Property Operating Expenses representing an amount paid
to a person, firm, corporation or other entity related to Landlord which is in
excess of the amount which would have been paid in the absence of such

Lease Term, including, without limitation, any regulation, order, or policy of
any quasi-official entity or body (e.g. a board of fire examiners or a public
utility or special district).

all Additional Rent.

13.13 General Waivers. One party's consent to or approval of any act by the
other party requiring the first party's consent or approval shall not be deemed
to waive or render unnecessary the first party's consent to or approval of any
subsequent similar act by the other party. No waiver of any provision hereof, or
any waiver of any breach of any provision hereof, shall be effective unless in
writing and signed by the waiving party. The receipt by Landlord of any rent or
payment with or without knowledge of the breach of any other provision hereof
shall not be deemed a waiver of any such breach. No waiver of any provision of
this Lease shall be deemed a continuing waiver unless such waiver specifically
states so in writing and is signed by both Landlord and Tenant. No delay or
omission in the exercise of any right or remedy accruing to either party upon
any breach by the other party under this Lease shall impair such right or remedy
or be construed as a waiver of any such breach theretofore or thereafter
occurring. The waiver by either party of any breach of any provision of this
Lease shall not be deemed to be a waiver of any subsequent breach of the same or
any other provisions herein contained.

13.14 Miscellaneous. Should any provisions of this Lease prove to be invalid or
illegal, such invalidity or illegality shall in no way affect, impair or
invalidate any other provisions hereof, and such remaining provisions shall
remain in full force and effect. Time is of the essence with respect to the
performance of every provision of this Lease in which time of performance is a
factor. Any copy of this Lease which is executed by the parties shall be deemed
an original for all purposes. This Lease shall, subject to the provisions
regarding assignment, apply to and bind the respective heirs, successors,
executors, administrators and assigns of Landlord and Tenant. The term "party"
shall mean Landlord or Tenant as the context implies. If Tenant consists of more
than one person or entity, then all members of Tenant shall be jointly and
severally liable hereunder. Submission of this Lease for review, examination or
signature by Tenant does not constitute an offer to lease, a reservation of or
an option for lease, and notwithstanding any inconsistent language contained in
any other document, this Lease is not effective as a lease or otherwise until
execution and delivery by both Landlord and Tenant. This Lease shall be
construed and enforced in accordance with the Laws of the State in which the
Leased Premises are located. The captions in this Lease are for convenience only
and shall not be construed in the construction or interpretation of any
provision hereof. When the context of this Lease requires, the neuter gender
includes the masculine, the feminine, a partnership, corporation, limited
liability company, joint venture, or other form of business entity, and the
singular includes the plural. The terms "must," "shall," "will," and "agree" are
mandatory. The term "may" is permissive. The term "governmental agency" or
"governmental authority" or similar terms shall include, without limitation, all
federal, state, city, local and other governmental and quasi-governmental
agencies, authorities, bodies, boards, etc., and any party or parties having
enforcement rights under any Private Restrictions. When a party is required to
do something by this Lease, it shall do so at its sole cost and expense without
right of reimbursement from the other party unless specific provision is made
therefor. Where Landlord's consent is required hereunder, the consent of any
Lender shall also be required. Landlord and Tenant shall both be deemed to have
drafted this Lease, and the rule of construction that a document is to be
construed against the drafting party shall not be employed in the construction
or interpretation of this Lease. Where Tenant is obligated not to perform any
act or is not permitted to perform any act, Tenant is also obligated to restrain
any others reasonably within its control, including agents, invitees,
contractors, subcontractors and employees, from performing such act. Landlord
shall not become or be deemed a partner or a joint venturer with Tenant by
reason of any of the provisions of this Lease.

                          BROKERS AND ENTIRE AGREEMENT

14.1 Corporate Authority. If Tenant is a corporation, each individual executing
this Lease on behalf of such corporation represents and warrants that Tenant is
validly formed and duly authorized and existing, that Tenant is qualified to do
business in the State in which the Leased Premises are located, that Tenant has
the full right and legal authority to enter into this Lease, and that he or she
is duly authorized to execute and deliver this Lease on behalf of Tenant in
accordance with its terms. Tenant shall, within thirty days after execution of
this Lease, deliver to Landlord a certified copy of the resolution of its board
of directors authorizing or ratifying the execution of this Lease and if Tenant
fails to do so, Landlord at its sole election may elect to terminate this Lease.

14.2 Brokerage Commissions. Tenant and Landlord each represents, warrants and
agrees that it has not had any dealings with any real estate broker(s), leasing
agent(s), finder(s) or salesmen, other than the Brokers (as named in Article 1)
with respect to the lease by it of the Leased Premises pursuant to this Lease,
and that it will indemnify, defend with competent counsel, and hold the other
party harmless from any liability for the payment of any real estate brokerage
commissions, leasing commissions or finder's fees claimed by any other real
estate broker(s), leasing agent(s), finder(s), or salesmen to be earned or due
and payable by reason of such party's agreement or promise (implied or
otherwise) to pay (or to have the other party pay) such a commission or finder's
fee by reason of its leasing the Leased Premises pursuant to this Lease.

                                       26.

<PAGE>

14.3 Entire Agreement. This Lease and the Exhibits (as described in Article 1),
which Exhibits are by this reference incorporated herein, constitute the entire
agreement between the parties, and there are no other agreements, understandings
or representations between the parties relating to the lease by Landlord of the
Leased Premises to Tenant, except as expressed herein. No subsequent changes,
modifications or additions to this Lease shall be binding upon the parties
unless in writing and signed by both Landlord and Tenant.

14.4 Landlord's Representations. Tenant acknowledges that neither Landlord nor
any of its agents made any representations or warranties respecting the
Property, the Building or the Leased Premises, upon which Tenant relied in
entering into the Lease, which are not expressly set forth in this Lease. Tenant
further acknowledges that neither Landlord nor any of its agents made any
representations as to (i) whether the Leased Premises may be used for Tenant's
intended use under existing Law, or (ii) the suitability of the Leased Premises
for the conduct of Tenant's business, or (iii) the exact square footage of the
Leased Premises, and that Tenant relies solely upon its own investigations with
respect to such matters. Tenant expressly waives any and all claims for damage
by reason of any statement, representation, warranty, promise or other agreement
of Landlord or Landlord's agent(s), if any, not contained in this Lease or in
any Exhibit attached hereto.

                                   ARTICLE 15

                                TELEPHONE SERVICE

     Notwithstanding any other provision of this Lease to the contrary:

     (a) Landlord shall provide Tenant access to such quantity of existing pairs
in the Building intra-building network cable ("INC") as is determined to be
available by Landlord in its reasonable discretion, provided that Tenant shall
be able to maintain all such INC and connections thereto as are existing as of
the Effective Date of this Lease. Tenant's access to the INC shall be solely by
arrangements made by Tenant, as Tenant may elect, directly with Pacific Bell or
Landlord (or such vendor as Landlord may designate, provided that Tenant may
utilize other vendors for the Leased Premises so long as neither such other
vendors nor their installations interfere with other tenants' service within the
Building and do not increase the costs to those tenants), and Tenant shall pay
all reasonable charges as may be imposed in connection therewith. Pacific Bell's
charges shall be deemed to be reasonable. Other than the foregoing, Landlord
shall have no responsibility for providing to Tenant any telephone equipment,
including wiring, within the Leased Premises or for providing telephone service
or connections from the utility to the Leased Premises, except as required by
law.

     (b) Tenant shall not alter, modify, add to or disturb any telephone wiring
in the Leased Premises or elsewhere in the Building without the Landlord's prior
written consent. Tenant shall be liable to Landlord for any damage to the
telephone wiring in the Building due to the act, negligent or otherwise, of
Tenant or any employee, contractor or other agent of Tenant. Tenant shall have
no access to the telephone closets within the Building, except in the manner and
under procedures established by Landlord. Tenant shall promptly notify Landlord
of any actual or suspected failure of telephone service to the Leased Premises.

     (c) All costs incurred by Landlord for the installation, maintenance,
repair and replacement of telephone wiring in the Building shall be a Property
Maintenance Cost.

     (d) Landlord makes no warranty as to the quality, continuity or
availability of the telecommunications services in the Building, and Tenant
hereby waives any claim against Landlord for any actual or consequential damages
(including damages for loss of business) in the event Tenant's
telecommunications services in any way are interrupted, damaged or rendered less
effective, except to the extent caused by the grossly negligent or willful act
or omission by Landlord, its agents or employees. Tenant acknowledges that
Landlord meets its duty of care to Tenant with respect to the Building INC by
contracting with a reliable third party vendor to assume responsibility for the
maintenance and repair thereof (which contract shall contain provisions
requiring such vendor to inspect the INC periodically (the frequency of such
inspections to be determined by such vendor based on its experience and
professional judgment), and requiring such vendor to meet local and federal
requirements for telecommunications material and workmanship). Subject to the
foregoing, Landlord shall not be liable to Tenant and Tenant waives all claims
against Landlord whatsoever, whether for personal injury, property damage, loss
of use of the Leased Premises, or otherwise, due to the interruption or failure
of telephone services to the Leased Premises.

         In Witness Whereof, Landlord and Tenant have executed this Lease as of
the respective dates below set forth with the intent to be legally bound thereby
as of the Effective Date of this Lease first above set forth.

                                    Exhibit E

                              RULES AND REGULATIONS

1.       No sign, placard, picture, advertisement, name or notice shall be
         installed or displayed on any part of the outside or inside of the
         Building without the prior written consent of Landlord, except that
         photographs and art work may be displayed within the Leased Premises.
         Landlord shall have the right to remove, at Tenant's expense and
         without notice, any sign installed or displayed in violation of this
         rule. All approved signs or lettering on doors and walls shall be
         printed, painted, affixed or inscribed at the expense of Tenant by a
         person chosen by Landlord.

2.       If Landlord objects in writing to any curtains, blinds, shades, screens
         or hanging plants or other similar objects attached to or used in
         connection with any window or door of the Premises, Tenant shall
         immediately discontinue such use. No awning shall be permitted on any
         part of the Premises. Tenant shall not place anything against or near
         glass partitions or doors or windows which may appear unsightly from
         outside the Premises.

3.       Tenant shall not obstruct any sidewalks, halls, passages, exits,
         entrances, elevators, escalators, or stairways of the Building. The
         halls, passages, exits, entrances, shopping malls, elevators,
         escalators and stairways are not open to the general public. Landlord
         shall in all cases retain the right to control and prevent access
         thereto of all persons whose presence in the judgment of Landlord
         would be prejudicial to the safety, character, reputation and interest
         of the Building and its tenants; provided that nothing herein
         contained shall be construed to prevent such access to persons with
         whom any tenant normally deals in the ordinary course of its business,
         unless such persons are engaged in illegal activities. No tenant and
         no employee or invitee of any tenant shall go upon the roof of the
         Building except as expressly provided in the Lease.

4.       The directory of the Building will be provided exclusively for the
         display of the name and location of Tenant only, and Landlord reserves
         the right to exclude any other names therefrom.

5.       All cleaning and janitorial services for the Premises shall be provided
         exclusively through Landlord, and except with the written consent of
         Landlord, no person or persons other than those approved by Landlord
         shall be employed by Tenant or permitted to enter the Building for the
         purpose of cleaning the same. Tenant shall not cause any unnecessary
         labor by carelessness or indifference to the good order and cleanliness
         of the Premises. Landlord shall not in any way be responsible to any
         tenant for any loss of property on the Premises, however occurring, or
         for any damage to any Tenant's property by the janitor or any other
         employee or any other person.

6.       Landlord will furnish Tenant, free of charge, with two keys to each
         door lock in the Premises. Landlord may make a reasonable charge for
         any additional keys. Tenant shall not make or have made additional
         keys, and Tenant shall not alter any lock or install a new additional
         lock or bolt on any door of its Premises. Tenant, upon the termination
         of its tenancy, shall deliver to Landlord the keys of all doors which
         have been furnished to Tenant, and in the event of loss of any keys so
         furnished, shall pay Landlord therefor.

7.       If Tenant requires telegraphic, telephonic, burglar alarm or similar
         services, Tenant shall first obtain, and comply with, Landlord's
         instructions in their installation.

8.       Any freight elevator shall be available for use by all tenants in the
         Building, subject to such reasonable scheduling as Landlord in its
         discretion shall deem appropriate. No equipment, materials, furniture,
         packages, supplies, merchandise or other property will be received in
         the Building or carried in the elevators except between such hours and
         in such elevators as may be designated by Landlord.

9.       Tenant shall not place a load upon any floor of the Premises which
