               each such Employee will be made quarterly ($[_________]),
               beginning on the date each such Employee becomes fully dedicated

               names of such Employees. If any such Employee ceases being fully
               dedicated to supporting the Alliance for any reason, Variagenics
               shall promptly notify Covance of such event and use its
               commercially reasonable efforts to replace any such Employee as
               soon as possible, including the reassignment of other Variagenics
               employees. The foregoing notwithstanding, the obligation of
               Covance to provide the funding specified in this Section 3(a)
               shall be abated (and an appropriate credit or refund shall be
               made) when and for as long as an Employee position is not filled.

     as outlined on Exhibit " A " attached hereto and incorporated herein by
     reference ("Premises").

3. USE. Tenant shall use the Premises for office, research and development and
other incidental uses. Landlord makes no representation or warranty that any
specific use of the Premises desired by Tenant is permitted pursuant to any
Laws.

4. TERM AND RENTAL. The term ("the Lease Term") shall commence on the date which
is the later of (i) the date Tenant Improvements are deemed Substantially
Complete by the projects architect and the City of San Jose such that permission
to occupy can be granted or (ii) December 15, 2000 (the `Commencement Date')
and ending one hundred twenty months thereafter. In addition to all other sums
payable by Tenant under this Lease, Tenant shall pay as base monthly rent (the
"Base Monthly Rent") for the Premises, the amount of Two Hundred Four Thousand
Six Hundred Twelve Dollars ($204,612) as the Base Monthly Rent for the initial
twelve month period. The Base Monthly Rent shall be due on or before the first
day of each calendar month during the Lease Term. The Base Monthly Rent due
beginning twelve months after the Commencement Date and every twelve months
thereafter shall be increased by Five percent (5%), and shall increase Five
percent (5%) annually thereafter. In addition to the Base Monthly Rent, each
and every month of the Lease Term the Tenant shall pay at the same time the Base
Monthly Rent is due, an additional fee ("Management Fee") equal to Three and
One Half percent (3 1/2%) of the Base Monthly Rent then due and payable. All
sums payable by Tenant under this Lease shall be paid in lawful money of the
United States of America, without offset or deduction except as set forth in
this Lease, and shall be paid to Landlord at such place or places as may be
designated form time to time in writing by Landlord. Base Monthly Rent for any
period less than a calendar month shall be prorated based on a Thirty (30) day
month. The initial month's Base Monthly Rent in the amount of Two Hundred Four
Thousand Six Hundred Twelve Dollars ($204,612) shall be paid in advance and
within three days of the execution of the Lease.

5. SECURITY DEPOSIT. Within three days of execution of the Lease Tenant shall
deposit a cash Security Deposit with Landlord in the amount of Two Hundred Four
Thousand Six Hundred Twelve Dollars ($204,612). Tenant shall also provide
additional Security Deposit in the form of a Letter of Credit acceptable to
Landlord in the amount of Two Million Four Hundred Fifty Five Thousand Three
Hundred Forty Four Dollars ($2,455,344). The Letter of Credit shall be provided
within thirty days of Lease execution and shall be drawn upon a bank reasonably
satisfactory to Landlord. The Landlord shall be entitled to draw upon the Letter
of Credit upon certification to the bank that a default by the Tenant exists and
is unsatisfied. The Letter of Credit shall be maintained until such time as the
Tenant has achieved six consecutive quarters

                                       1
<PAGE>

of operational profitability. Operational Profit shall mean actual profit
without consideration of any write-off related to stock adjustments. The Letter
of Credit, if drawn upon, or the Cash Security Deposit if utilized to satisfy
any default, shall be restored within five days of notification to the Tenant by
Landlord of such an event. Failure to restore shall be considered a default
notwithstanding anything to the contrary contained herein. Likewise the Letter
of Credit shall be renewed at lease sixty days prior to its expiration to avoid
a default under this Lease. Landlord may utilize the Security Deposits to cure
any defaults by Tenant or reimburse Landlord for any sums required to be spent
to satisfy the covenants and obligations of the Tenant. In the event of any
transfer by Landlord of their interest in the Premises the Security Deposits
herein shall likewise be transferred to the succeeding owner of the fee title.

6. LATE CHARGES. Tenant hereby acknowledges that late payment by Tenant to
Landlord of rent and other sums due hereunder will cause Landlord to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to,
administrative, processing, accounting charges, and late charges, which may be
imposed on Landlord by the terms of any contract, revolving credit, mortgage or
trust deed covering the Premises. Accordingly, if any installment of rent or any
other sum due form Tenant shall not be received by Landlord or Landlord's
designee within Ten (10) days after the date on which such payment was due,
Tenant shall pay to Landlord a late change equal to Five percent (5%) of such
overdue amount, which late charge shall be due and payable on the same date that
the overdue amount question was due. The parties hereby agree that such late
charge represents a fair and reasonable estimate of the costs Landlord will
incur by reason of late payment by Tenant. Acceptance of such late charge by
Landlord shall in no event constitute a waiver of Tenant's default with respect
to such overdue amount nor prevent Landlord form exercising any of the other
rights and remedies granted hereunder. In the event that a late charge is
payable hereunder, whether or not collected, for three (3) installments of Base
Monthly Rent, then rent shall automatically become due and payable quarterly in
advance, rather than monthly, notwithstanding any provision of this Lease to the
contrary. In the event of a natural disaster affecting the Premises this
paragraph 6. does not apply.

J. TENANT'S CONTRIBUTION TO TENANT IMPROVEMENT COSTS. Tenant's obligation to pay
the cost of constructing the Tenant Improvements ("Tenant's Cost Obligation")
shall be limited to the actual Tenant Improvement less the Tenant Improvement
Allowance. Tenant shall not be required to post a letter of credit in an amount
equal to the Tenant Improvement Cost less the Tenant Improvement Allowance nor
shall Tenant be required to post cash. Tenant shall covenant to pay to Landlord
Tenant's Cost Obligation no later than Ten (10) days after receipt of a
statement and reasonable documentation of the Tenant Improvement Costs from
Landlord. Tenant shall be entitled to all investment tax credit, depreciation,
and other tax attributes relating to the Tenant Improvements paid for by Tenant.
At the Expiration Date or sooner termination of the Lease, all Tenant
Improvements shall be surrendered to Landlord in accordance with the terms of
the Lease.

K. TENANT'S RIGHT TO ENTER. Tenant and its authorized representatives shall have
the right to enter the Building at all reasonable times for the purpose of
inspecting the progress of the construction of the Tenant Improvements. Landlord
shall give Tenant at least Thirty (30) days prior written notice of its
estimated date for Substantial Completion of the Premises, so that Tenant may
cause its fixtures and equipment (phones and cabling needs to be addressed
immediately to be integrated into the work flow) to be ordered. When the
construction of the Tenant Improvements has proceeded to the point where
Tenant's work of installing its fixtures and equipment in the Building can be
commenced in accordance with good construction practice, Landlord also shall
notify Tenant to that effect and shall permit Tenant and its authorized
representatives and contractors to have access to the Building for a period of
not less than Fourteen (14) days for the purpose of installing Tenant's trade
fixtures and equipment. Any such fixturization by Tenant will be preformed in a
manner that will not materially interfere with the orderly construction and
completion of the Tenant Improvements nor delay the issuance of a right to
occupy by a representative of the city of San Jose.

L. CONSTRUCTION WARRANTY FOR THE BUILDING. Notwithstanding anything to the
contrary in the Lease, effective upon delivery of the Premises to Tenant,
Landlord does hereby warrant (a) that the Building Shell, Tenant Improvements
and Premises, upon such delivery, fully comply with all applicable covenants,
conditions or restrictions and the rules, regulations, codes, statutes,
ordinances, and laws of all governmental and quasi-governmental authorities
having jurisdiction over the Premises; (b) that the Tenant Improvements are
constructed in accordance with the Final Tenant Improvement Plans and in a good
and workmanlike manner; (c) that the roof membrane of the Building is in good
condition and repair; (d) that the heating, ventilation and air condition system
of the Building and all other systems are in good operating condition and
repair; (f) that all new material and equipment installed at the Premises
conform to the Final Tenant Improvement Plans and are new and of good quality.
Notwithstanding anything to the contrary contained in the Lease, Tenant's
acceptance of the Premises shall not be deemed a waiver of the foregoing
warranty or any other warranty of Landlord under the Lease, and Landlord shall
promptly repair all violations of the warranty set forth in this paragraph at
its sole cost and expense. Landlord's obligations with respect to the correction
of such defects shall be limited to the cost to correct the defective work and
Landlord shall not be liable for any consequential damages or other loss
incurred by Tenant.

M. RISK OF LOSS. Risk of loss of the Premises prior to the Commencement Date of
the Lease shall be borne by Landlord. At all times prior to the Commencement
Date, Landlord at its sole cost and expense shall maintain so-called contingent
liability and broad form "builders risk" insurance with coverage in an amount
equal to the replacement cost of the Building Shell plus the Tenant Improvement
Cost. The insurance policy (a) shall be in a form reasonable satisfactory to
Tenant, (b) shall be carried with a company reasonably acceptable to Tenant, and
(c) shall provide that such policy shall not be subject to cancellation or
change except after at least Ten (10) days prior written notice to Tenant. If
the Building is damaged or destroyed and provided sufficient insurance proceeds
exist to rebuild the Building Shell and Tenant Improvements, Landlord shall
promptly and diligently complete construction of the Tenant Improvements in
accordance with this Lease and all insurance proceeds with respect to the loss
shall be paid to an independent depository reasonably acceptable to Landlord and
Tenant, for disbursement to the contractors completing the Building as the work
progresses in accordance with customary institutional lending practices.

N. ACCOUNTING. Landlord shall submit to Tenant on a monthly basis an accounting
of all Tenant Improvement Costs, certified as true and correct by Landlord.
Tenant shall have the right to audit the books, records and supporting documents
of Landlord during normal business hours, after giving Landlord notice to

                                       5
<PAGE>

the extent reasonably necessary to determine the accuracy of any accounting.
Within Forty Five (45) days after Substantial Completion, Landlord shall render
to Tenant a final and detailed accounting of all Tenant Improvement Costs paid
by Landlord and Tenant, certified as true and correct by Landlord. Tenant shall
have the same audit rights as set forth above with respect to the monthly
accountings.

O. TENANT DELAYS. For purposes of this Lease, the foregoing shall be deemed
"Tenant Delays": any delays in the construction of the Tenant Improvements or
otherwise achieving Substantial Completion arising in whole or part form: (a)
Tenant's failure to submit plans and information or review and approve
information including the Tenant Improvement Cost Estimate by the dates set
forth in this Paragraph 7; (b) as a result of written change orders made by
Tenant pursuant to the terms of this Paragraph 7 after final approval of the
Final Tenant Improvement Plans, to the extent specified in any written change
order approved by Tenant in writing; or (c) any other acts or omissions of
Tenant, its employees, agents, contractors or invitees. As a result of these
delays, if any, Tenant shall determine in good faith any obligation they might
have as such a result to otherwise begin paying rent to the Landlord prior to
the actual completion as a result of such delays, if any. Time is of the essence
for all parties and all parties shall endeavor to have the Premises ready for
occupancy as soon as is reasonably possible. Landlord should not be placed in
the position of incurring additional costs as a result of untimely decisions or
delays. If Tenant has so impacted the Landlord the Tenant shall decide what fair
compensation the Landlord may be entitled.

P. COMMENCEMENT DATE. The Lease Term shall not commence until the later of (i)
the date Tenant Improvements are deemed Substantially Complete by the projects
architect and the City of San Jose such that permission to occupy can be granted
or (ii) December 15, 2000 (the `Commencement Date') and ending one hundred
twenty months thereafter. If Landlord, for any reason whatsoever, cannot
Substantially Complete the Premises by December 15, 2000 this Lease shall not be
void or voidable nor shall Landlord be liable to Tenant for any loss or damage
resulting therefrom; but in such event the commencement and termination dates of
the Lease and all other dates affected thereby shall be revised to conform to
the Commencement Date. Landlord and Tenant shall execute a confirmation of the
Commencement Date promptly following the occurrence thereof.

8. ACCEPTANCE OF PREMISES AND COVENANTS TO SURRENDER.

A. ACCEPTANCE. As soon as Landlord reasonably believes that the Premises are
Substantially Complete, as defined in Paragraph 7 hereof, Landlord and Tenant
shall together walk through and inspect the work and prepare a written "punch
list" of incomplete or defective construction to present to the General
Contractor. Landlord shall use its reasonable efforts to cause the General
Contractor to complete and/or repair any items on the "punch list" within Thirty
(30) days after the parties have prepared the "punch list" or as soon thereafter
as practical in the exercise of due diligence. After completion of the "punch
list", Tenant shall be deemed to have accepted the Premises.

B. CORRECTION OF DEFECT. Notwithstanding anything to the contrary in the Lease,
Tenant's acceptance of the Premises or submission of a "punch list" shall not be
deemed a waiver of Tenant's right to have defects in the Tenant Improvements and
the Premises repaired at Landlord's sole expense. Tenant shall give notice to
Landlord whenever any such defect becomes reasonably apparent, and Landlord
shall repair such defect as soon as reasonably practical. Landlord also hereby
assigns to Tenant all warranties with respect to the Premises, which would
reduce Tenant's maintenance obligations hereunder and shall cooperate, with
Tenant to enforce all such warranties.

C. SURRENDER. Tenant agrees on the last day of the Lease Term, or promptly
following any sooner termination, to surrender the Premises to Landlord in the
condition received by Tenant, reasonable wear and tear, acts of God, casualties,
condemnation, Hazardous Materials as defined in Paragraph 17 hereof (other than
those stored, used, generated, or disposed of by Tenant, its employees, agents,
contractors and invitees in or about the Premises in violation of "Law" as
defined in Paragraph 11), and Alterations as defined in Paragraph 10 made by
Tenant which Landlord has indicated that Tenant shall not be required to remove,
excepted. Tenant agrees, at its sole cost, to remove all non category 5 or
better phone and data cabling form the suspended ceiling and repair or replace
broken ceiling tiles, and re-level the ceiling if required by Landlord at the
end of the Lease Term. Tenant shall ascertain from Landlord within Thirty (30)
days before the Expiration Date (or promptly following any sooner termination of
this Lease) whether Landlord will require Tenant to remove any Alternations made
by Tenant at the Premises, provided that at the time of approval, Landlord has
specified that the Alteration will have to be removed at the termination of the
lease; If Landlord shall so require, then Tenant shall remove such Alterations
as Landlord may designate and shall repair any damage to the Premises occasioned
by the removal before the Expiration Date or promptly following any sooner
termination at Tenant's sole cost and expense. On or before the end of the Lease
Term or promptly following

                                       6
<PAGE>

any sooner termination, Tenant shall remove all of its personal property and
trade fixtures form the Premises, and all property and fixtures not so removed
shall be deemed to be abandoned by Tenant. If the Premises are not surrendered
at the end of the Lease Term or sooner termination of this Lease in the
condition required by this paragraph, Tenant shall indemnify, defend and hold
harmless Landlord against loss or liability resulting from delay by Tenant in so
surrendering the Premises including, without limitation, any claims made by any
succeeding tenant founded on such delay.

9. USE PROHIBITED. Tenant shall not (a) commit, or suffer to be committed, any
waste or nuisance upon the Premises, or (b) allow any sale by auction upon the
Premises, or (c) allow the Premises to be used for any unlawful purpose, or (d)
place any loads upon the floor, walls, or ceiling which endanger the structure,
or (e) use any machinery or apparatus which will vibrate or shake the Premises
or the Building so as to damage the Premises other than ordinary wear and tear
or otherwise in violation of applicable Law, (f) place any harmful liquids,
waste materials, or Hazardous Materials in the drainage system of, or upon or in
the soils surrounding, the Building in violation of applicable Law. No
materials, supplies, equipment, finished products or semi-finished products, raw
materials or articles of any nature or any waste materials, refuse, scrap or
debris shall be stored upon or permitted to remain on any portion of the
Premises outside of the Building except in waste containers.

10. ALTERATIONS AND ADDITIONS.

A. CONSTRUCTION OF ALTERATIONS. Tenant may construct non-structural alterations,
additions and improvements ("Alterations") in the Premises without Landlord's
prior approval, if the per incidence cost of the Alteration in question does not
exceed One hundred thousand and no/100 Dollars ($100,000) provided that Tenant
first notify Landlord of such proposed improvements and provide Landlord at all
times with an updated set of drawings relative to the Premises. And Landlord
will advise, within 48 hours, whether it is to be restored when the lease
terminates If Tenant desires to make Alterations costing more than One hundred
thousand and no/100 Dollars ($100,000) or structural Alterations, Tenant shall
first obtain Landlord's consent, which consent shall not be unreasonably
withheld, and, if Landlord does not notify Tenant in writing of its reasonable
disapproval of such Alteration within seven (7) days following Tenant's written
request for approval and delivery to Landlord of the proposed plans, then
Landlord shall be deemed to have approved the proposed Alternation. Landlord
shall within the above-stated seven (7) day period advise Tenant in writing as
to whether Landlord shall require removal of any Alteration in question upon the
Expiration Date or earlier termination of the Lease Term. Tenant agrees that it
will not proceed to make any Alterations until (a) Tenant has obtained all
required governmental approvals and permits, as agreed upon by Landlord and
Tenant and (b) Tenant has provided Landlord reasonable security, in form
reasonably approved by Landlord, to protect Landlord against mechanics' lien
claims. Tenant further agrees to provide Landlord (a) written notice of the
anticipated start date and the actual start date of the work, and (b) a complete
set of as-built drawings upon completion of the work. All Alterations shall be
(a) performed in compliance with all applicable Laws and (b) maintained,
replaced or repaired by Tenant at Tenant's sole costs and expense.

B. OWNERSHIP OF ALTERNATIONS. Landlord and Tenant agree to create a list of
items which shall constitute items which need not be removed by Tenant at the
end of the lease. For those items which do need removal, pursuant to this
paragraph, Landlord shall give Tenant 45 days notice to remove such items at the
termination of the tenancy. All Alterations, trade fixtures and personal
property installed in the Premises at Tenant's expense ("Tenant's Property")
shall at all times remain Tenant's property and Tenant shall be entitled to all
depreciation, amortization and other tax benefits with respect thereto. Except
for Alterations which cannot be removed without structural injury to the
Premises, Tenant may remove Tenant's Property from the Premises at any time,
provided Tenant, at its expense, repairs any damage caused by such removal.
Landlord shall have no lien or other interest whatsoever in any item of Tenant's
Property located in the Premises or elsewhere, and Landlord hereby waives all
such liens and interest. Within Ten (10) days following Tenant's request,
Landlord shall execute documents in reasonable form to evidence Landlord's
waiver of any right, title, lien or interest in Tenant's Property located in the
Premises.

11. MAINTENANCE OF PREMISES.

A. TENANT MAINTENANCE. Subject to Landlord's obligations as set forth in this
Lease and to the amortization of capital items as set forth in Paragraph 11,
Tenant shall, at its sole cost, keep and maintain, repair and replace, the
Premises and appurtenances and every part hereof, including but not limited to,
the interior non-load bearing walls, the roof membrane, the sidewalks, the
parking areas, the landscape areas, the elevator, the plumbing, electrical and
HVAC systems, and the Tenant Improvements in good and sanitary order, condition,
and repair. With respect to the roof membrane, if Tenant is required to repair
the membrane during the tenancy in a manner which extends the useful life

                                       7
<PAGE>

of the roof membrane substantially beyond the length of the lease, a prorated
amount reflecting this repair shall be credited to tenant. Notwithstanding the
foregoing, Landlord shall repair and maintain in good condition, at Landlord's
sole cost, the structural portions of the Premises at all times during the Lease
Term, including the foundation, exterior walls, load-bearing walls, and the roof
structure. Tenant shall provide Landlord with a copy of service contracts
between Tenant and (a) a licensed air-conditioning and heating contractor and
(b) a licensed elevator maintenance contractor, which contracts shall provide
for maintenance of the HVAC and elevator equipment at such intervals as may be
reasonably required by the manufacturer of such equipment. Subject to the
obligations of Landlord hereunder and the amortization of capital items as set
forth in Paragraph 11, Tenant shall pay the cost of all air-conditioning and
heating equipment repairs or replacements which are either excluded from such
service contract or any existing equipment warranties. Tenant shall be
responsible for the preventive maintenance of the roof membrane, which
responsibility shall be deemed properly discharged if (a) Tenant contracts with
a licensed roof contractor who is reasonably satisfactory to both Tenant and
Landlord, at Tenant's sole cost, to inspect the roof membrane at least every Six
(6) months, with the first inspection due Six (6) months after the Commencement
Date, and (b) Tenant performs, at Tenant's sole cost, all routine preventive
maintenance recommendations made by such contractor within a reasonable time
after such recommendations are made. Such preventive maintenance might include
acts such as clearing storm gutters and drains, removing debris from the roof
membrane, trimming trees overhanging the roof membrane, applying coating
materials to seal roof penetrations, repairing blisters, and other routine
measures Upon Landlord's advance written request, Tenant shall provide to
Landlord a copy of such preventive maintenance contract and paid invoices for
the recommended work for which Tenant is responsible. Subject to Landlord's
obligations hereunder and to the amortization of capital items set forth below,
Tenant agrees, at its expense, to water, maintain and replace, when necessary,
any shrubbery and landscaping.

B. EXCLUDED COSTS. Notwithstanding anything to the contrary in this Lease, in no
event shall Tenant have any obligations to perform or to pay directly, or to
reimburse Landlord for, all or any portion of the following repairs,
maintenance, improvements, replacements, premiums, claims, losses, fees,
charges, costs and expense (collectively "Costs") nor shall any portion of the
Tenant Improvement Costs (as defined in Paragraph 7) consist of the following
items, all of which shall be the responsibility of Landlord:

     1.   LOSSES CAUSED BY OTHERS. Costs occasioned by acts, omission or
          violation of any covenants, statutes, laws, orders, rules,
          underwriter's requirements, regulations, private restrictions,
          building codes or ordinances (collectively, "Law"), a
          misrepresentation, or breach of this Lease, by Landlord or its agents,
          employees, contractors, subcontractors, tenant, or invitees.

     2.   CASUALTIES AND CONDEMNATIONS. Costs occasioned by fire, acts of God,
          or other casualties or by the exercise of the power of eminent domain,
          provided that Tenant will pay insurance deductibles but only to the
          extent approved by Tenant in writing in accordance with Paragraph 12
          of this Lease.

     3.   REIMBURSABLE EXPENSES. Costs for which Landlord has a right of
          reimbursement from others or for which Landlord actually receives
          reimbursement.

     4.   CONSTRUCTION DEFECTS AND COMPLIANCE WITH LAW. Costs (a) relating to
          construction defects; or (b) required to conform the Premises to the
          Final Tenant Improvement Plans.

     5.   HAZARDOUS MATERIALS. Except to the extent caused by the disposal,
          release, emission generation, or storage of the Hazardous Material in
          question by Tenant, its agents, employees, invitees or contractors in
          violation of Law, Costs incurred to investigate the presence of any
          Hazardous Materials, Costs to respond to any claim Hazardous Material

12. INSURANCE.

                                       8
<PAGE>

A. TENANT'S USE. Tenant shall not use, or permit the Premises, or any part
thereof, to be used for any unlawful purpose and no use shall be made or
permitted to be made of the Premises, nor acts done, which will cause an
increase in premiums for the insurance to be maintained by Landlord (unless
Tenant pays for the cost of such increase) or a cancellation of any insurance
policy covering the Premises. Tenant shall, at its sole cost and expense, comply
with any and all reasonable requirements pertaining to said Premises of any
insurance organization or company necessary for the maintenance of reasonable
fire and public liability insurance covering the Premises, excluding structural
improvements or alterations not related to Tenant's specific and particular use.

B. LANDLORD'S INSURANCE. Landlord agrees to purchase and keep in force
Landlord's liability, loss of rents, and fire and extended coverage insurance in
an "all risk" form covering the Premises and all of the Tenant Improvements paid
for by Landlord in the amount of their full replacement value. Tenant agrees to
pay to the Landlord as additional rent, on demand, the cost of such insurance as
evidenced by insurance billings to Landlord. Payment shall be due to Landlord on
the later of: (a) Thirty (30) days after written invoice to Tenant; or (b)
Twenty (20) days prior to the due date of such premiums. Tenant's obligation
under this paragraph will be prorated to reflect the commencement and
termination dates of this Lease. In the event that Landlord, in its sole
discretion, elects to purchase earthquake insurance, Tenant's obligation to pay
for the cost of any earthquake insurance premiums shall be limited to an amount
equal to or less than Two (2) times the cost of the fire and extended coverage
premiums. If the Project is located in a flood zone, Landlord shall also
maintain flood insurance insuring the Building and Tenant Improvements paid for
by Landlord for their full replacement value, and Tenant shall pay for flood
insurance premiums in the manner set forth herein. Tenant shall have no
obligation with respect to the payment of insurance policy premiums as set forth
above to the extent such premiums are attributable to any time period prior to
the date on which payments of Base Monthly Rent commence pursuant to Paragraph 4
hereof.

C. TENANT'S INSURANCE. Tenant, at its sole cost, agrees to insure Tenant's
Property in an amount Tenant deems appropriate for its protection and to obtain
worker's compensation as required by Law. Tenant, at its sole cost, shall also
maintain commercial general liability insurance for occurrences within the
Premises of $3,000,000 combined single limit for bodily injury and property
damage. Tenant shall name Landlord as an additional insured under such
commercial general liability policy, and shall deliver a copy of such policy to
Landlord prior to Landlord prior to the Commencement Date and upon any renewal
of such policy. Tenant's commercial general liability policy shall provide for
Thirty (30) days' prior written notice to Landlord of any cancellation or
termination or reduction in coverage.

D. INSURANCE DEDUCTIBLES. Tenant shall have the right to specify in writing
within thirty days of the anniversary date of the Commencement Date the
deductible of any insurance policy to be carried by Landlord under this Lease
and shall reimburse Landlord, in the manner set forth in Paragraph 12 (B), for
the premiums payable with respect to insurance policies for which Tenant is
responsible under Paragraph 12 (B) containing the deductible so specified by
Tenant or on insurance policies for which Tenant fails to specify a deductible
amount within Thirty (30) days following Landlord's written demand for such
deductible specification. In the event of damage to the Premises covered by
Landlord's "all risk" casualty policy (and not caused by the negligence or
willful misconduct of Landlord or Landlord's employees, agents, contractors,
subcontractors, or invitees), Tenant shall pay the amount of any deductible
under such policy if this Lease is not terminated in connection with such
casualty as provided in Paragraph 26 hereof, provided Tenant has approved in
writing in advance the amount of such deductible.

E. WAIVER. Notwithstanding anything to the contrary in this Lease, Landlord and
Tenant hereby waive any rights each may have against the other on account of any
loss or damage that is caused or results from a risk which is actually insured
against, which is required to be insured against under this Lease, or which
would normally be covered by a standard form full replacement value "all risk
extended coverage" policy of casualty insurance, regardless of whether such loss
or damage is due to the negligence of Landlord or Tenant or of their respective
agents, employees, subtenants, contractors, assignees, invitees or any other
cause. Each party shall use its reasonable efforts to obtain from their
respective insurance companies a waiver of any right of subrogation, which said
insurance company may have against the Landlord or the Tenant, as the case may
be. If, after such reasonable efforts, such insurance policy cannot be obtained
with such waiver of subrogation, or it such waiver of subrogation is only
available at additional cost and the party for whose benefit the waiver is not
obtained does not pay such additional cost, then the party obtaining such
insurance shall immediately notify the other party of that fact and shall be
relieved of pursuing the waiver further.

13. TAXES. Tenant shall be liable for, and shall pay prior to delinquency, all
taxes and assessments levied against Tenant's Property, and agrees to pay, as
additional rental, all real estate taxes and assessment installments (special or
general) or other impositions or charges which may be levied with respect to the
Premises including real estate tax

                                       9
<PAGE>

increases due to a sale or other transfer of the Premises. It is understood and
agreed that Tenant's obligation under this paragraph will be prorated to reflect
the commencement and termination dates of this Lease. Tenant shall pay such
taxes on the later of (a) Twenty (20) days after written notice from Landlord
(which notice shall contain a coy of the tax bill in question); or (b) Ten (10)
days before the tax delinquency date. If at any time during the Lease Term a
tax, excise on rents, business license tax, or any other tax, however described,
is levied or assessed against Landlord, as a substitute or addition in whole or
in part for real estate taxes assessed or imposed on land or Building, Tenant
shall pay and discharge its share of such tax or excise on rents or other tax
before it becomes delinquent. In the event that a tax is placed, levied, or
assessed against the Landlord and the taxing authority takes the position that
the Tenant cannot pay and discharge its pro rata share of such tax on behalf of
the Landlord, then at the sole election of the Landlord, the Landlord may
increase the rental charged hereunder by the exact amount of such tax and Tenant
shall pay such increase as additional rent hereunder. Notwithstanding anything
to the contrary herein, Tenant shall not be required to pay any portion of any
tax or assessment: (a) levied on Landlord's rental income, unless such tax or
assessment is imposed in lieu of real property taxes; (b) in excess of the
amount which would be payable if such tax or assessment were paid in
installments over the longest possible term; (c) imposed on land and
improvements other than the Premises; (d) attributable to Landlord's net income,
inheritance, gift, transfer, franchise or estate taxes, or (e) imposed with
respect to Hazardous Materials unless Tenant caused such Hazardous Materials.
Tenant may in good faith contest any real property taxes provided that Tenant
indemnifies Landlord form any loss or liability in connection therewith. Tenant
shall have no obligation with respect to the payment of taxes or assessments as
set forth above to the extent such taxes or assessments are attributable to any
time period prior to the date on which payments of Base Monthly Rent commence
pursuant to Paragraph 4 hereof.

14. UTILITIES. Tenant shall pay directly to the providing utility all water,
gas, heat, light, power, telephone and other utilities supplied to the Premises
and site. Landlord shall not be liable for a loss of or injury to property,
however occurring, though or in connection with or incidental to furnishing or
failure to furnish nay of utilities to the Premises and Tenant shall not be
entitled to abatement or reduction of any portion of the rent so long as any
failure to provide and furnish the utilities to the Premises is not due to the
negligence, or willful misconduct of Landlord, its agents, employees or
contractors. Notwithstanding the foregoing, if utilities are not available to
the Premises for a period of Thirty (30) consecutive days or more and such
failure does not result from the acts or omissions of Tenant, its employees,
agents, contractor or invitees, Tenant shall be entitled to an abatement of rent
to the extend of the interference with Tenant's use of the Premises occasioned
hereby, which abatement shall commence on the Thirty First (31st) consecutive
day of such interference and continue until the affected services are restored
so that the Premises are reasonably suitable for Tenant's intended use, and if
such interference is not corrected so that the Premises are reasonably suitable
for Tenant's intended use within One Hundred Eighty (180) days following the
interference or interruption, then Landlord or Tenant shall be entitled to
terminate this Lease. Notwithstanding anything to the contrary in this Lease,
the above abatement of rent shall only apply in the event Tenant has not
occupied the Premises affected by the interference during the preceding Thirty
(30) days.

15. FREE FROM LIENS. Tenant shall keep the Premises free from any liens
arising out of any work performed for Tenant, provided, however, that if
Tenant, in good faith, elects to contest such lien, Tenant shall furnish and
maintain a bond or other security reasonably acceptable to Landlord and
Tenant shall not then be deemed in default under this Lease. In the event
Tenant fails to discharge any such lien within Ten (10) days after receiving
notice of the filing, Landlord shall be entitled to discharge such lien at
Tenant's expense and any work performed, materials furnished, or obligations
incurred by Tenant or claimed to have been all resulting costs incurred by
Landlord, including attorney's fees, shall be due from Tenant as additional
rent.

16. COMPLIANCE WITH GOVERNMENTAL REGULATIONS. Tenant shall, at its sole cost
and expense, comply with the requirements of all Laws now in force, or which
may hereafter be in force, either (a) pertaining to Tenant's specific and
particular use of the Premises or (b) arising because of an Alteration made
by Tenant, and shall faithfully observe in the use of the Premises all Laws
now in force or which may hereafter be in force. The judgment of any court of
competent jurisdiction, or the admission of Tenant in any action or
proceeding against Tenant, whether Landlord be a party thereto or not, that
Tenant has violated any such ordinance or statute in Tenant's use of the
Premises, shall be conclusive of that fact as between Landlord and Tenant. At
the Commencement Date, the Premises shall conform to all requirements of
covenants, conditions, restrictions and encumbrances ("CC & R's"), all
underwriter's requirements, and all Laws applicable thereto. Tenant shall not
be required to construct or pay the cost of complying with any CC & R's,
underwriters requirements or Law requiring construction of improvements in
the Premises which are properly capitalized under generally accepted
accounting principles, unless (a) such compliance is necessitated solely
because of Tenant's particular and specific use of the Premises or (b) such
compliance is necessitated because of Alternations made by Tenant. Any
structural requirements or Costs necessitated by CC & R's, underwriters'
requirements or Laws which are imposed on buildings or real estate generally
(as opposed to the Premises because of Tenant's specific and

                                       10
<PAGE>

particular use) shall be performed by Landlord and the cost of such item or
improvement shall be allocated as follows: Landlord and Tenant shall establish
the useful life of the improvement based upon generally accepted accounting
principles. Tenant shall pay a proportion of the actual cost equal to the cost
of such improvement or item paid by Landlord to the third party contractor
performing the maintenance or furnishing the replacement times a fraction, the
numerator of which is the number months remaining in the initial Lease Term, and
the denominator of which is the useful life of the improvement in months. Tenant

G. INTERFERENCE. If the Premises should become unsuitable for Tenant's use as a
consequence of the presence of any Hazardous Material which does not result form

use of the Premises occasioned thereby form the date of the Interfering Event,
which abatement shall commence on the Thirty First (31st) consecutive day of
such interference and continue until the affected services are restored so that

18. INDEMNITY. As a material part of the consideration to be rendered to
Landlord, Tenant hereby waives all claims against Landlord for damages to goods,
wares and merchandise, and all other personal property in, upon or about said
Premises and for injuries to persons in or about said Premises, from any cause
arising at any time, and Tenant shall indemnify and hold Landlord exempt and
harmless from any damage or injury to any person, or to the goods, wares and

and reasonable attorney's fees incurred in defending such claims except to the
extent of the negligence or willful misconduct of Landlord or its agents,
employees, contractors, subcontractors, or a breach of this Lease by Landlord.

negligence or willful misconduct of Landlord, or its agents, employees,
contractors, subcontractors or invitees; (b) a breach of Landlord's obligations
or representations under this Lease; or (c) any Hazardous Material which was not

Tenant at its expense prior to the Expiration Date or promptly following any
earlier termination of the Lease Term, and repair any damage or injury to the
Premises caused thereby, and if not so removed by Tenant then Landlord may have
same so removed at Tenant's expense. Landlord shall cooperate with and assist

should be brought for the possession of the Premises, for the recovery of any
sum due hereunder, or because of the breach of any other covenant herein, the
losing party shall pay to the prevailing party a reasonable attorneys fee as
part of its costs which shall be deemed to have accrued on the commencement of
such action and shall be enforceable whether or not such action is prosecuted to
judgment. In addition, the prevailing party shall be entitled to recover all
costs and expenses including reasonable attorney's fees incurred by the
prevailing party in enforcing any judgment or reward against the other party.
The foregoing provision relating to post-judgment costs is intended to be
severable from all other provisions of this Lease.

21. TENANT'S DEFAULT. In the event of Tenant's failure to perform any of its
covenants or agreements under this Lease, Landlord shall give Tenant written
notice of such failure and shall give Thirty (30) days or such longer time as
may be reasonably required by Tenant to cure said failure in the exercise of
reasonable diligence provided Tenant commences the cure within said Thirty (30)
day period and thereafter diligently prosecutes such cure to completion. If
Tenant so fails to perform its obligations under this Lease, the occurrence of
any of the following shall constitute a material default and breach of this
Lease by Tenant: (a) Any failure by

                                       13
<PAGE>

Tenant to pay any rent under this Lease on or before the date such rent is due
under this Lease or to restore the Security Deposits to the amounts required
within the periods provided in the Lease; (b) a failure by Tenant to observe and
perform any other provision of this Lease to be observed or performed by Tenant,
where such failure continues for Thirty (30) days after written notice thereof
by Landlord to Tenant; provided, however, that if the nature of such default is
such that the same cannot reasonably be cured within such Thirty (30) day period
Tenant shall not be in default if Tenant shall within such period commence such
cure and thereafter diligently prosecute the same to completion; (c) the making
by Tenant of any general assignment for the benefit of creditors; the filing by
or against Tenant of a petition filed against Tenant, the same is dismissed
within Sixty (60) days after the filing; the appointment of a trustee or
receiver to take possession of substantially all of Tenant's assets located at
the Premises or of Tenant's interest in this Lease, where possession is not
restored to Tenant within Sixty (60) days; or the attachment, execution or other
judicial seizure of substantially all of Tenant's assets located at the Premises
or of Tenant's interest in this Lease, where such seizure is not discharged
within Sixty (60) days. The notice requirements set forth herein are in lieu of
and not in addition to the notices required by California Code of Civil
Procedure Section 1161, provided that such notices are given in the manner
required by such statute. Any notice given by Landlord to Tenant pursuant to
California Civil Code Section 1161 with respect to any failure by Tenant to pay
rent under this Lease on or before the date the rent is due under this Lease
shall provide Tenant with a period of no less than Ten (10) days to pay such
rent or quit.

A. REMEDIES. In the event of any such default by Tenant, then in addition to any
other remedies available to Landlord at law or in equity, Landlord shall have
the immediate option to terminate this Lease and all rights of Tenant hereunder
by giving written notice of such intention to terminate. In the event that
Landlord shall elect to so terminate this Lease then Landlord may recover form
Tenant: (a) the worth at the time of award of any unpaid rent which had been
earned at the time of such termination; plus (b) the worth at the time of award
of the amount by which the unpaid rent which would have been earned after
termination until the time of award exceeds the amount of such rental loss for
the same period Tenant proves could have been reasonably avoided; plus (c) the
worth at the time of award of the amount by which the unpaid rent for the
balance of the Lease Term after the time of award exceeds the amount of such
rental loss for the same period that Tenant proves could be reasonably avoided;
plus (d) any other amount necessary to compensate Landlord for all the detriment
proximately caused by Tenant's failure to perform its obligations under this
Lease or which in the ordinary course of things would be likely to result
therefrom. The term "rent", as used herein, shall be deemed to be and to mean
the minimum monthly installments of Base Monthly Rent and all other sums
required to be paid by Tenant pursuant to the terms of this Lease, all other
sums being deemed to be additional rent due hereunder. As used in (a) and (b)
above, the "worth at the time of the award" is to be computed by allowing
interest at the rate of the discount rate of the Comerica Bank plus Five (5%)
percent per annum. As used in (c) above, the "worth at the time of award" is to
be computed by discounting such amount at the discount rate of the Coamerica
Bank at the time of award plus One (1 %) percent.

B. RIGHT TO RE-ENTER. In the event of any such default by Tenant, that results
in the termination of the Lease, Landlord shall also have the right to re-enter
the Premises and remove all persons and property form the Premises; such
property may be removed and stored in a public warehouse or elsewhere at the
cost of and for the account of Tenant and disposed of by Landlord in any manner
permitted by law.

C. ABANDONMENT. If Landlord shall take possession of the Premises pursuant to
legal proceeding or pursuant to any notice provide by law, then if Landlord does
not elect to terminate this Lease as provided in Paragraph 21 (A) above, then
the provisions of California Civil Code Section 1951.4 (Landlord may continue
the Lease in effect after Tenant's breach and abandonment and recover rent as it
becomes due, if Tenant has aright to sublet or assign only to reasonable
limitations), as amended from time to time, shall apply and Landlord may form
time to time, recover all rental as it becomes due.

22. SURRENDER OF LEASE. The voluntary or other surrender of this Lease by
Tenant, or a mutual cancellation thereof, shall not automatically effect a
merger of the Lease with Landlord's ownership of the Premises. Instead, at the
option of Landlord, Tenant's surrender may terminate all or any existing
sublease or subtenants, or may operate as an assignment to Landlord of any or
all such subleases or subtenants, or may operate as an assignment to Landlord of
any or all such subleases or subtenants thereby creating a direct relationship
between Landlord and any subtenants.

23. LANDLORD'S DEFAULT. In the event of Landlord's failure to perform any of
its covenants or agreements under this Lease, Tenant shall give Landlord written
notice of such failure and shall give Thirty (30) days or such longer

                                       14
<PAGE>

time as may be reasonably required by Landlord to cure said failure in the
exercise of reasonable diligence provided Landlord commences the cure within
said Thirty (30) day period and thereafter diligently prosecutes such cure to
completion. If Landlord so fails to perform its obligations under this Lease,
then, and only then, will Landlord be in default under the Lease, and, in
addition to its other rights and remedies, Tenant shall have the right to cure
Landlord's default and (a) to recover from Landlord the cost of the cure
together with interest thereon at the prime rate charged by Union Bank, main San
Francisco branch, plus five percent (5%)per annum from the date of the
expenditure until the date of the repayment. In addition, upon any such failure
by Landlord, Tenant shall give notice by registered or certified mail to any
person or entity with a security interest in the Premises ("Mortgagee") that has
delivered Tenant written notice of its interest in the Premises, and shall
provide such Mortgagee a reasonable opportunity to cure such failure, including
such time to obtain possession of the Premises by power of sale or judicial
foreclosure, if such should prove necessary to effectuate a cure. Tenant agrees
that each of the Mortgagees to whom this Lease has been assigned is an expressed
third party beneficiary hereof. Tenant shall not make any prepayment of rent
more than One (1) month in advance without the prior written consent of such
Mortgagee. Tenant waives any right under California Civil Code Section 1950.7 or
nay other present or future law to the collection of any payment or deposit from
such Mortgagee or any purchaser at a foreclosure sale of such Mortgagee's
interest unless such Mortgagee or such purchaser shall have received and not
refunded the applicable payment or deposit.

be in writing and given under this Lease shall be personally delivered,

25. ENTRY BY LANDLORD. Upon Twenty-Four (24) hours advance notice to Tenant
(except in the event of an emergency where no such prior notice shall be
required) and provided that Landlord does not unreasonably interfere with
Tenant's use of the Premises, Tenant shall permit Landlord and his agents to
enter upon the Premises at all reasonable times subject to any reasonable safety
and/or security regulations of Tenant for the purposed of inspecting the same,
maintaining the Premises, or making repairs or alterations as may be required to
fulfill Landlord's obligations hereunder without any abatement or reduction of
rent or without any liability to Tenant for any loss of occupation or quiet
enjoyment of the Premises thereby occasioned; and Tenant shall permit Landlord
and his agents, at any time within One Hundred Eighty (180) days prior to the
Expiration Date (or any time during the Lease if Tenant is in default
hereunder), to place upon said Premises any "For Lease" signs and exhibit the
Premises to real estate brokers and prospective tenants at reasonable hours upon
reasonable prior notice.

26.      DESTRUCTION OF PREMISES.

A. OBLIGATION TO RESTORE. In the event of damage or destruction to the
Building or Premises or any portion thereof by any casualty during the Lease
Term, Landlord shall forthwith repair the same to the condition the Building
or Premises were in immediately before the destruction (to the extent
permitted by Laws), provided such casualty is (a) of a type required to be
insured against by Landlord under the terms of this Lease and for which
Landlord has actually received insurance proceeds sufficient to repair the
damage or destruction or (b) is actually insured against by Landlord and for
which Landlord has actually received insurance proceeds sufficient to repair
the damage or

                                       15
<PAGE>

destruction (herein collectively referred to as an "Insured Casualty"). In
the event of damage or destruction of the Premises by a casualty of a type
which is not required to be insured against by Landlord under this Lease, and
which is not actually insured against by Landlord (herein referred to as an
"Uninsured Casualty"), Landlord shall restore the Premises to the same
condition as they were in immediately before such destruction (to the extent
permitted by Laws) and this Lease shall not terminate; provided, that if in
the case of such Uninsured Casualty the cost of restoration exceeds Five (5%)
percent of the then replacement cost of the Building, Landlord may elect to
terminate this Lease by giving written notice to Tenant within Fifteen (15)
days after determining the replacement cost and furnishing reasonable
evidence thereof to Tenant. If Landlord so elects to terminate this Lease,
Tenant, with Fifteen (15) days after receiving Landlord's notice to
terminate, can elect to pay to Landlord at the time Tenant notifies Landlord
of its election, the difference between Five (5%) percent of the replacement
cost of the Building and the actual cost of restoration, in which case
Landlord shall restore the Premises and this Lease shall not terminate. If
Landlord so elects to terminate this lease and Tenant does not elect to
contribute the cost of restoration as provided herein, this Lease shall
terminate. In all events Landlord shall not be required to restore or replace
Tenant's Alternations or replace Tenant's Property unless Landlord receives
insurance proceeds which cover such losses. Provided the damage is not due to
the negligence or willful misconduct of Tenant, its employees, agents,
contractors or invitees, Tenant shall be entitled to a proportionate
reduction of Base Monthly Rent during the period of damage and restoration,
such proportionate reduction to be based upon the extent to which the damage
and making of repairs shall interfere with Tenant`s use of the Premises.

B. TENANT'S RIGHT TO TERMINATE. In the event of damage or destruction to the
Premises, Landlord shall furnish to Tenant a good faith written estimate from
Landlord's architect or construction consultant of the time period needed to
restore the Premises, within Thirty (30) days after the date of the damage or
destruction in question. If such estimate indicates that the repair or
restoration of the Premises cannot be made within One Hundred Eight (180) days
after the date of the damage or destruction, and Landlord has not terminated the
Lease pursuant to Paragraph 27 (A) above, Tenant may, at its option, terminate
this Lease by giving written notice to Landlord of such election within Fifteen
(15) days after receipt of Landlord's estimate. Tenant shall also have the right
to terminate this Lease if the actual restoration of the Premises is not
effectuated within Two Hundred Seventy (270) days after the date of the
casualty. Further, Tenant shall have the right to terminate this Lease if the
Building is damaged by any peril within Twelve (12) months of the last day of
the Lease Term to such an extent that more than Thirty (30%) percent of the
floor area of the Building is rendered unusable by Tenant for a period of more
than Sixty (60) days. The provision of Section 1932, Subdivision 2, and of
Section 1933, Subdivision 4, of the Civil Code of the State of California and
any other similarly enacted statute are waived by Tenant and the provisions of
this Paragraph 26 shall govern in the case of such destruction.

27.      ASSIGNMENT OR SUBLEASE.

A. CONSENT BY LANDLORD. IN the event Tenant desires to assign this Lease or any
interest therein including, without limitation, a pledge, mortgage or other
hypothecation, or sublet the Premises or any part thereof except as set forth
above with respect to "Permitted Transferees", Tenant shall deliver to Landlord
copies of the proposed agreement, the financial statements of the assignee or
subtenant, and any additional information as reasonably required by Landlord.
Landlord shall then have a period of seven (7) business days, unless Bob Granum
is personally notified earlier in which case it shall be 48 hours, following
receipt of such notice, documents and information within which to notify Tenant
in writing that Landlord elects (a) to permit Tenant to assign or sublet such
space to the name assignee/subtenant, or (b) to refuse consent, provided
Landlord shall not unreasonably refuse such consent. If Landlord should fail to
notify Tenant in writing of such election within said seven (7) day period,
Landlord shall be deemed to have elected to permit the assignment or sublease in
question. No assignment or subletting by Tenant shall relieve Tenant or any
guarantor of any obligations under this Lease or any guaranty. Landlord's
consent to the proposed assignment or sublease shall not be unreasonably
withheld or delayed, provided and upon condition that (a) the proposed uses will
not violate this Lease or any Laws; (b) the appropriateness of the proposed
assignee or subtenant has sufficient financial worth to undertake the
responsibility involved. (c) The proposed assignment or sublease shall be in a
form reasonably satisfactory to Landlord. Whether or not Landlord grants its
consent to the proposed sublease or assignment, Tenant agrees to reimburse
Landlord for all reasonable attorneys' fees and costs incurred by Landlord in
connection with the review of the proposed sublease or assignment.

B. ASSIGNMENT OR SUBLETTING CONSIDERATION. Any rent or lump sum consideration
received for an assignment actually or constructively received by Tenant under
any assignment or any sublease in excess of $6.00 per net square foot, shall be
shared with the Landlord in the ratio of Fifty percent to the Landlord and Fifty
percent to the Tenant. Landlord's right to the allocation of bonus rent is an
independently negotiated term of the Lease, constitutes a material

                                       16
<PAGE>

inducement for the Landlord to enter into the Lease, and is agreed as between
the parities to be commercially reasonable. These provisions do not apply to
occupancy by subsidiaries of Tenant, or of United Microelectronics Corporation
(UMC) or Foxconn or their subsidiaries.

C. NO RELEASE. Any assignment or sublease shall be made only if, and shall not
be effective until, the assignee or subtenant shall execute, acknowledge and
deliver to Landlord an agreement, in form and substance reasonably satisfactory
to Landlord, whereby the assignee or subtenant shall assume all of the
obligations of this Lease on the part of Tenant to be performed or observed and
shall be subject to all of the covenants, agreements, terms, provisions and
conditions contained in this Lease. Notwithstanding any sublease or assignment
and the acceptance of rent or additional rent by Landlord from any subtenant or
assignee, Tenant and any guarantor shall and will remain fully liable for the
payment of the rent and additional rent due, and to become due hereunder, for
the performance of all of the covenants, agreements, terms, provisions and
conditions contained in the Lease on the part of Tenant to be performed and for
all acts and omissions of any licensee, subtenant, assignee or any other person
claiming under or through any subtenant or assignee that shall be in violation
of any of the terms and conditions of this Lease, and any such violation shall
be deemed to be a violation by Tenant hereunder. Tenant shall further indemnify,

all rents due form any assignment or subletting to Landlord as security for
performance of its obligations under this Lease and Landlord may collect such
rents as Tenant's attorney-in-fact, except that Tenant may collect such rents
unless a default occurs as described in such election Paragraph 22 above. The
termination of this Lease due to Tenant's default shall not automatically
terminate any assignment or sublease then in existence; at the election of
Landlord such assignment or sublease shall survive the termination of this Lease
and, upon such election, the assignee or subtenant shall attorn to Landlord and
Landlord shall undertake the obligations of the Tenant under the sublease or
assignment; provided the Landlord shall not be liable for prepaid rent, security
deposits or other defaults of the Tenant to the subtenant or assignee, or any
acts or omissions of Tenant-, its agents, employees, contractors and invitees.

28. CONDEMNATION. If any part of the Premises shall be taken for any public or

purchase in lieu thereof, and a apart thereof remains which is susceptible of
occupation hereunder, this Lease shall as to the part so taken, terminate as of
the date title shall vest in the condemnor or purchaser, and the Base Monthly
Rent payable hereunder shall be adjusted so that Tenant shall be required to pay
for the remainder of the Lease Term only such portion of the rent as the value
of the part remaining after such taking bears to the value of the entire
Premises prior to such taking; but in such event Tenant shall have the option to
terminate this Lease as of the date when title to the part taken vests in the
condemnor or purchaser if the taking or condemnation of the Premises is such
that the remaining space unaffected by the taking or condemnation is not
reasonably suitable for Tenant's use or the conduct of Tenant's business. If a
part or all of the Premises are taken all compensation awarded upon such taking
shall go to Landlord and the Tenant shall have no claim thereto; provided,
however, that nothing contained herein shall be deemed to waive or release
Tenant's interest in any separate award for (a) loss of or damage to Tenant's
trade fixtures, Alternations, or personal property; (b) interruption of Tenant's
business; (c) Tenant's loss of goodwill; (d) Tenant's moving cost; (e) Tenant's

Procedures Section 1265.130 or any similar statue now or hereafter enacted.

or other conveyance of the Premises, the transferor shall be and hereby is
entirely freed and relieved of all covenants and obligations of the "Landlord"
hereunder accruing after the date of the conveyance. Notwithstanding the
foregoing, the transferor shall not be relieved of its obligations under this
Lease, unless and until it transfers the cash security deposit to its successor
and the successor assumes in writing the obligations of Landlord accruing on and
after the effective date of the transfer. Furthermore, the transferor shall not
be relieved of it obligations hereunder accruing after the date of the transfer
unless the assignee or successor in question has a net worth reasonably
sufficient to assure performance of the obligations of Landlord hereunder, and
Landlord furnishes reasonable evidence thereof to Tenant.

<PAGE>

Tenant agrees to promptly execute and deliver any reasonable documents, which
may be required to effectuate such subordination within Ten (10) days
following Landlord's request. Notwithstanding such subordination but subject
to the terms and conditions of this Lease, Tenant's right to quiet possession
of the Premises shall not be disturbed so long as Tenant is not in default
hereunder. Notwithstanding anything to the contrary in the Lease,

covenant or condition herein contained shall not be deemed to be a waiver of
such term, covenant or condition or any subsequent breach of the same or any
other term, covenant or condition herein contained. The subsequent acceptance
of rent hereunder by Landlord (or the payment thereof by Tenant) shall not be
deemed to be a waiver of any preceding breach by Landlord or Tenant of any
term, covenant or condition of this Lease, other than the failure of Tenant
to pay the particular rental accepted by Landlord, regardless of the party's
knowledge of such preceding breach at the time acceptance of such preceding
breach at the time of acceptance of rent. No delay or omission in the
exercise of any right or remedy by Landlord shall impair such right or remedy
or be construed as a waiver thereof by Landlord. No act or conduct Landlord,
including, without limitation, the acceptance of keys to the Premises, shall
constitute acceptance of the surrender of the Premises by Tenant before the

require Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent to or approval of any subsequent act by Tenant.

termination of the Lease shall be construed to be a tenancy from month-to-month,
terminable on Thirty (30) days written notice form either party, and Tenant

of the greater of the current asking rents for similar space or Base Monthly

plus all other amounts payable by Tenant under this Lease. Any holding over
shall otherwise be on the terms and conditions herein specified, except those
provisions relating to the Lease Term and any options to extend or renew, which
provisions shall be of no further force and effect following the expiration of
the applicable exercise period. Tenant shall indemnify, defend and hold landlord
harmless form all loss or liability (including, without limitation, any loss or

paid in advance and acknowledging that there are not, to the party's knowledge,
any uncured defaults on the part of the other party hereunder or specifying such
defaults if they are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrance on the Premises or a purchaser of
Tenant's assets or leasehold interest. Landlord's or Tenant's failure to deliver
such statement within such time shall be conclusive upon the party not providing
the statement that: (a) this Lease is in full force and effect, without
modification except as may be represented by the requesting party; (b) there are
not uncured defaults in the requesting party's performance. Upon the advance
written request of Landlord's, Tenant shall furnish Landlord with Tenant's most
