Landlord acquired the Land and any existing improvements on the Land 
from Chevron Land and Development Company, a Delaware corporation 
(hereinafter called "Seller");

     WHEREAS, contemporaneously with the closing of Landlord's purchase

upon which Landlord is willing to provide funds for such construction

improvements thereon and the equipment and other personal property 
purchased with funds provided by Landlord; and 

     WHEREAS, Landlord and Tenant desire by this Lease to amend, 
restate, replace and supersede the Prior Lease in its entirety, 
effective as of the date hereof;

     NOW, THEREFORE, in consideration of the rent to be paid and the 
covenants and agreements to be performed by Tenant, as hereinafter set 
forth, Landlord does hereby LEASE, DEMISE and LET unto Tenant for the 
term hereinafter set forth the Land, together with:

          (i)  Landlord's interest in any and all buildings and other 
real property improvements on the Land from time to time, including 
improvements hereafter erected on the Land by Tenant, and including, but 
not limited to, mechanical, electrical, HVAC and other building systems 
attached to future buildings and improvements constructed on the Land by 
Tenant (hereinafter called the "Improvements");

          (ii)  all easements and rights-of-way now owned or hereafter 
acquired by Landlord for use in connection with the Land or Improvements 
or as a means of access thereto;

          (iii)  all right, title and interest of Landlord, now owned or 
hereafter acquired, in and to (A) any land lying within the right-of-way 
of any street, open or proposed, adjoining the Land, (B) any and all 
sidewalks and alleys adjacent to the Land and (C) any strips and gores 
between the Land and abutting land (except strips and gores, if any, 
between the Land and abutting land owned by Landlord, with respect to 
which this Lease shall cover only the portion thereof to the center line 
between the Land and the abutting land owned by Landlord).

The Land and all of the property described in items (i) through (iii) 
above are hereinafter referred to collectively as the "Real Property".

     In addition to conveying a leasehold in the Real Property as 
described above, Landlord hereby grants, assigns and leases to Tenant 
for the term of this Lease the right to use and enjoy (and, to the 
extent the following consist of contract rights, to enforce) any 
interests or rights of Landlord in, to or under the following, to the 
extent, but only to the extent, that such interests or rights are 
assignable and have been or will be transferred to Landlord by Seller 
under the Contract, transferred to Landlord because of Tenant's purchase 
thereof with funds advanced by Landlord as described in subparagraph 
9(ae) below, assigned to Landlord by Tenant pursuant to subparagraph 
9(af) of the Prior Lease or pursuant to subparagraph 9(ae) below or 
otherwise transferred to Landlord by reason of Landlord's status as the 
owner of the Real Property: (a) any goods, equipment, furnishings, 
furniture, chattels and tangible personal property of whatever nature 
that are located on the Real Property and all renewals or replacements 
of or substitutions for any of the foregoing; (b) the rights of 
Landlord, now existing or hereafter arising, under Permitted 
Encumbrances (including the Development Contracts, as defined below), 
and (c) any other general intangibles, permits, licenses, franchises, 
certificates, and other rights and privileges related to the Real 
Property that Tenant (rather than Landlord) would have acquired if 
Tenant had itself acquired the Real Property as the purchaser under the 
Contract.  All of the property, rights and privileges described above in 
this paragraph whether now existing or hereafter arising, are 
hereinafter collectively called the "Personal Property".  The Real 
Property and the Personal Property are hereinafter sometimes 
collectively called the "Leased Property."

     Provided, however, the leasehold estate conveyed hereby and 
Tenant's rights hereunder are expressly made subject and subordinate to 
the Permitted Encumbrances (as hereinafter defined) and to any other 
claims or encumbrances not asserted by Landlord itself or by third 
parties lawfully claiming through or under Landlord.

equal or exceed the Maximum Construction Allowance available under this 
Lease; provided, that if Landlord sells its interest in the Leased 
Property pursuant to the Purchase Agreement before the Base Rental 
Commencement Date, the last Advance Date shall be the Designated Payment

Commencement Date or a Base Rental Date under the definitions below.

or proceeding is brought with respect to the matter for which the 
expenses and fees were incurred.

Tenant during the term of this Lease for the construction of new 
Improvements or for the alteration of then existing Improvements.  A 
subsequent Construction Project may involve demolition of then existing 
Improvements which are no longer needed or which must be removed to 
accommodate new Improvements, subject to the requirements of Paragraph 
6(b) below.  All construction work planned or done contemporaneously 
shall constitute a single Construction Project for purposes of this 
Lease, notwithstanding that such work may be done in stages or performed

Lease.

     (af)  Debt.  "Debt" means, with respect to any Person, (a)

     (ag)  Default.  "Default" means any event which, with the passage 
of time or the giving of notice or both, would constitute an Event of 
Default.

     (ah)  Default Rate.  "Default Rate" means a floating per annum rate 
equal to five percent (5%) above the Prime Rate in effect from time to 
time.  However, for purposes of computing interest on any past due 
reimbursement which is payable by Tenant upon demand under this Lease, 
the "Default Rate" for the first ten (10) Business Days after a demand 
for such reimbursement is made upon Tenant shall (1) equal zero, if the 
reimbursement required is $10,000 or less, and (2) if the required 
reimbursement is more than $10,000, not exceed the Prime Rate in effect 
on the date demand for such reimbursement is first made.  Further, in no

which Landlord may consent at the request of Tenant pursuant to 
subparagraph 10(b) below.

     (ak)  Effective Rate.  "Effective Rate" means, for each 
Construction Period and Base Rental Period, the rate which equals the 
Spread plus the rate per annum determined by dividing (A) LIBOR for such 
Construction Period or Base Rental Period, as the case may be, by (B) 
100% minus the Eurodollar Rate Reserve Percentage for such Construction 
Period or Base Rental Period.  If LIBOR or the Eurodollar Rate Reserve 
Percentage changes from period to period, then the Effective Rate shall 
be automatically increased or decreased as of the date of such change, 
as the case may be.  After the Base Rental Commencement Date, however, 
Landlord will provide notice of any such change (as required by 
Paragraph 3(a)) after the same shall take effect and at least five (5) 
Business Days prior to the next following Base Rental Date.  If for any 
reason Landlord determines in good faith that it is impossible or 
impractical to determine the Effective Rate with respect to a given 
Construction Period or Base Rental Period in accordance with the 
preceding sentences, then the "Effective Rate" for that Construction 
Period or Base Rental Period shall equal the Spread plus any published 
index or per annum interest rate determined in good faith by Landlord's 
Parent to be comparable to LIBOR at the beginning of the first day of 
that period.  A comparable interest rate might be, for example, the then 
existing yield on short term United States Treasury obligations (as 
compiled by and published in the then most recently published United 
States Federal Reserve Statistical Release H.15(519) or its successor 
publication), plus or minus a fixed adjustment based on Landlord's 
Parent's comparison of past eurodollar market rates to past yields on 
such Treasury obligations.  Any determination by Landlord of the 
Effective Rate hereunder shall, in the absence of clear and demonstrable 
error, be conclusive and binding.

     (al)  Environmental Cutoff Date.  "Environmental Cutoff Date" means 
the later of the dates upon which (i) this Lease terminates, or (ii) 
Tenant surrenders possession and control of the Leased Property.

1995 executed by Tenant in favor of Landlord.

     (an)  Environmental Laws.  "Environmental Laws" means any and all 
existing and future Applicable Laws pertaining to safety, health or the 
environment, or to Hazardous Substances or Hazardous Substance 
Activities, including without limitation the Comprehensive Environmental 
Response, Compensation, and Liability Act of 1980, as amended by the 
Superfund Amendments and Reauthorization Act of 1986 (as amended, 
hereinafter called "CERCLA"), and the Resource Conservation and Recovery 
Act of 1976, as amended by the Used Oil Recycling Act of 1980, the Solid 
Waste Disposal Act Amendments of 1980, and the Hazardous and Solid Waste 
Amendments of 1984 (as amended, hereinafter called "RCRA").

Environmental Cutoff Date; (ii) any violation on or prior to the 
Environmental Cutoff Date of any applicable Environmental Laws relating 
to the Leased Property or to the ownership, use, occupancy or operation

that occurs or is alleged to have occurred on or prior to the 
Environmental Cutoff Date; or (iv) any claim, demand, cause of action or 
investigation, or any action or other proceeding, whether meritorious or 
not, brought or asserted against any Indemnified Party which directly or 
indirectly relates to, arises from, is based on, or results from any of 
the matters described in clauses (i), (ii), or (iii) of this 
subparagraph 1(ao) or any allegation of any such matters.  For purposes 
of determining whether Losses constitute "Environmental Losses," as the 
term is used in this Lease, any actual or alleged Hazardous Substance 
Activity or violation of Environmental Laws relating to the Leased 
Property will be presumed to have occurred prior to the Environmental 
Cutoff Date unless Tenant establishes by clear and convincing evidence 
to the contrary that the relevant Hazardous Substance Activity or 
violation of Environmental Laws did not occur or commence prior to the 
Environmental Cutoff Date.  Environmental Losses incurred by or asserted 
against a particular Indemnified Party shall include Losses relating to 
or arising out of or as a result of any matters listed above even when 
such matters are caused by the negligence of that particular Indemnified 
Party or any other Indemnified Party.  However, Losses incurred by or 
asserted against a particular Indemnified Party and proximately caused 
by (and attributed by any applicable principles of comparative fault to) 
the wilful misconduct, Active Negligence or gross negligence of that 
Indemnified Party or its Affiliates, agents or employees will not 
constitute Environmental Losses of such Indemnified Party for purposes 
of this Lease.

Business Day preceding the first day of such period.  If for any reason 
Landlord's Parent in good faith determines that it is impossible or 
impractical to determine LIBOR with respect to a given Construction 
Period or Base Rental Period in accordance with the preceding sentences, 
or if Landlord's Parent shall determine that it is unlawful (or any 
central bank or governmental authority shall assert that it is unlawful) 
for Landlord, Landlord's Parent or any Participant to maintain Funding 
Advances hereunder during any Construction Period or Base Rental Period 
for which Carrying Costs or Base Rent is computed by reference to LIBOR, 
then "LIBOR" for that Construction Period or Base Rental Period shall 
equal the rate which is fifty basis points (50/100 of 1%) above the Fed

not include any payments received by Landlord that Landlord has paid to

Landlord is holding as Escrowed Proceeds.  For purposes of computing the 
total Qualified Payments (and other amounts dependent upon Qualified 
Payments, such as Stipulated Loss Value) paid to or received by Landlord 
as of any date, payments described in the preceding clauses (1) through 
(4) will be considered as Escrowed Proceeds, not Qualified Payments, 
until they are actually applied as Qualified Payments by Landlord, which 
Landlord will do upon the first Advance Date or Base Rental Date which 
is at least three (3) Business Days after Landlord's receipt of the same

determination of Quick Assets and rated at least (i) A (in the case of 
securities with an original maturity greater than one year) or A-2 (in 
the case of securities with an original maturity of one year or less) or 
the equivalent thereof by Standard and Poor's Corporation, or (ii) A-2 
(in the case of securities with an original maturity greater than one

by Tenant as described in subparagraph 6(b)(i).  Notwithstanding the 
foregoing, "Scope Change" shall not include refinement, correction and 
detailing of plans or other items submitted to Landlord by Tenant.  As

therewith) significantly reduce any excess of the fair market value of

Rent, the Upfront Fee, Agency Fees, Special Participation Fees or 
Commitment Fees reduce Stipulated Loss Value.

     (cj)  Subsidiary.  "Subsidiary" means, with respect to any Person, 
any Affiliate of which at least a majority of the securities or other

Paragraphs, subparagraphs or other subdivisions shall refer to the 
corresponding Paragraphs, subparagraphs or subdivisions of this Lease, 
unless specific reference is made to another document or instrument.  
References herein to any Schedule or Exhibit shall refer to the 
corresponding Schedule or Exhibit attached hereto, which shall be made a 
part hereof by such reference.  All capitalized terms used in this Lease 
which refer to other documents shall be deemed to refer to such other 
documents as they may be renewed, extended, supplemented, amended or 
otherwise modified from time to time, provided such documents are not 
renewed, extended or modified in breach of any provision contained 
herein or therein or, in the case of any other document to which 
Landlord is a party or of which Landlord is an intended beneficiary, 
without the consent of Landlord.  All accounting terms not specifically 
defined herein shall be construed in accordance with GAAP.  The words 
"this Lease", "herein", "hereof", "hereby", "hereunder" and words of 
similar import refer to this Lease as a whole and not to any particular 
subdivision unless expressly so limited.  The phrases "this Paragraph" 
and "this subparagraph" and similar phrases refer only to the Paragraphs

not exclusive.  Other capitalized terms are defined in the provisions 
that follow.

  2  Term.

     (a)  Scheduled Term.    The term of this Lease (herein called the 
"Term") shall commence on and include the effective date hereof, and end 
at 8:00 A.M. on December 1, 2003 (or the next following Business Day if 
December 1, 2003 is not a Business Day), unless sooner terminated as 
herein provided.

     (b)  Early Termination By Tenant.  Provided that Tenant is still in 
possession of the Leased Property and has not breached its obligation to 
make or have made any payment required by Paragraph 2 of the Purchase 
Agreement on any prior Designated Payment Date, Tenant may elect to 
terminate this Lease, effective as of midnight of any Advance Date or 
Base Rental Date, by giving Landlord (and Participants) an irrevocable 
notice of such election at least ninety (90) days prior to the effective 
date of the termination.  If Tenant elects to so terminate this Lease, 
then on the Advance Date or Base Rental Date on which this Lease is to 
be terminated, not only must Tenant pay all unpaid Rent, Tenant must 
also satisfy its obligations under the Purchase Agreement.  The payment 
of any unpaid Rent and satisfaction of Tenant's obligations under the 
Purchase Agreement shall be a condition precedent to the effectiveness 
of any early termination of this Lease by Tenant.

  3  Rental.

     (a)  Base Rent.  Tenant shall pay Landlord rent (herein called 
"Base Rent") in arrears, in currency that at the time of payment is 
legal tender for public and private debts in the United States of 
America, in monthly installments on the Base Rental Commencement Date 
and on each Base Rental Date through the end of the Term.  Each payment 
of Base Rent must be received by Landlord no later than 10:00 a.m. (San 
Francisco time) on the date it becomes due; if received after 10:00 a.m. 
(San Francisco time) it will be considered for purposes of this Lease as 
received on the next following Business Day.  Each installment of Base 
Rent shall represent rent allocable to the Construction Period or Base 
Rental Period ending on the date on which the installment is due.  
Landlord shall notify Tenant in writing of the Base Rent due for the 
Construction Period ending on the Base Rental Commencement Date (if any) 
and of the Base Rent due for each Base Rental Period at least five (5) 
Business Days prior to the Base Rental Commencement Date or Base Rental 
Date on which such period ends, but any failure by Landlord to so notify 
Tenant shall not constitute a waiver of Landlord's right to payment.  If 
Tenant or any Applicable Purchaser purchases Landlord's interest in the 
Leased Property pursuant to the Purchase Agreement, any Base Rent for 
the month ending on the date of purchase and all outstanding Additional 
Rent shall be due on the Designated Payment Date in addition to the 
purchase price and other sums due Landlord under the Purchase Agreement.  
The Base Rent payable on the Base Rental Commencement Date shall equal 
the difference (if any) between (a) total Carrying Costs that would have 
been added to the Outstanding Construction Allowance on such date if the 
Construction Allowance available hereunder were not limited to the 
Maximum Construction Allowance, and (b) the Carrying Costs actually 
added on such date to the Outstanding Construction Allowance.  The Base 
Rent for each Base Rental Period shall equal (A) Stipulated Loss Value 
on the first day of such Base Rental Period, times (B) the Effective 
Rate with respect to such Base Rental Period, times (C) the number of 
days in such Base Rental Period, divided by (D) three hundred sixty 
(360).  Assume, only for the purpose of illustration: that a 
hypothetical Base Rental Period contains exactly thirty (30) days; that 
on the first day of such Base Rental Period Stipulated Loss Value is 
$300,000,000; and that the Effective Rate computed with respect to the 
applicable Base Rental Period is six percent (6%).  Under such 
assumptions, the Base Rent for the hypothetical Base Rental Period will 
equal:

            $300,000,000 x 6% x 30/360, or $1,500,000.

     (b)  Upfront Fee.  As provided in the Term Sheet, upon execution 
and delivery of this Lease by Landlord, Tenant shall pay Landlord an 
upfront fee (herein called the "Upfront Fee") (less the deposit already 
paid by Tenant pursuant to the Term Sheet).  The Upfront Fee shall 
represent Additional Rent for the first Construction Period.

     (c)  Agency Fees.  Upon execution and delivery of this Lease by 
Landlord, and on December 1 of 1996 and each calendar year thereafter 
during the Term, Tenant shall pay Landlord an administrative fee (herein 
called "Agency Fees") as provided in the Term Sheet; provided that if 
December 1 of any calendar year during the Term does not fall on a 
Business Day, the payment of Agency Fees otherwise then due shall become 
due on the next following Business Day. Each payment of the Agency Fee 
shall represent Additional Rent for the Construction Period or Base 
Rental Period during which it is paid.

     (d)  Special Participation Fee.  Upon execution and delivery of 
this Lease by Landlord, Tenant shall also pay Landlord a fee (herein 
called a "Special Participation Fee"), for the account of each 
Participant who has committed by the terms of its participation 
agreement with Landlord to provide or maintain Funding Advances of 
$70,000,000 or more, assuming that the entire Maximum Construction 
Allowance is used by Tenant.  Such fee shall equal four basis points 
(4/100 of 1%) times such Funding Advances which the Participant has 
committed to provide or maintain.  The Special Participation Fees shall 
also represent Additional Rent for the first Construction Period.

     (e)  Commitment Fees.  For each Construction Period during the Term 
Tenant shall pay Landlord a fee (herein called a "Commitment Fee") equal 
to (1) twelve basis points (12/100 of 1%), times (2) the difference at 
the end of the first day of such Construction Period between (A) the 
Maximum Construction Allowance and (B) the Outstanding Construction 
Allowance, times (3) the number of days in such Construction Period, 
divided by (4) three hundred sixty (360).  Tenant shall pay Commitment 
Fees in arrears on January 2, April 1, July 1 and October 1 of each 
calendar year, beginning with January 2, 1996 and continuing regularly 
throughout the Term so long as Commitment Fees accrue because of a 
difference between the Maximum Construction Allowance and the 
Outstanding Construction Allowance; provided that if any of such dates 
does not fall on a Business Day, the payment of Commitment Fees 
otherwise then due shall become due on the next following Business Day; 
provided, further, if any Commitment Fees shall have accrued and remain 
unpaid on the Designated Payment Date, such accrued unpaid Commitment 
Fees shall be due on the Designated Payment Date; and provided, further, 
that the first such Commitment Fee due on January 2, 1996 shall be 
prorated to reflect a period commencing on the effective date of this 
Lease and ending on December 31, 1995.

     (f)  Additional Rent.  All amounts which Tenant is required to pay 
to or on behalf of Landlord pursuant to this Lease, together with every 
charge, premium, interest and cost set forth herein which may be added 
for nonpayment or late payment thereof, shall constitute rent (all such 
amounts, other than Base Rent, are herein called "Additional Rent").

     (g)  Interest and Order of Application.  The Base Rent and all 
Additional Rent shall bear interest, if not paid when first due, at the 
Default Rate in effect from time to time from the date due until paid; 
provided, that nothing herein contained will be construed as permitting 
the charging or collection of interest at a rate exceeding the maximum 
rate permitted under Applicable Laws.  Landlord shall be entitled to 
apply any amounts paid by or on behalf of Tenant hereunder against any 
Rent then past due in the order the same became due or in such other 
order as Landlord may elect.

     (h)  Net Lease.  It is the intention of Landlord and Tenant that 
the Base Rent and all other payments herein specified shall be 
absolutely net to Landlord.  Subject only to the other express 
provisions of this Lease (including, without limitation, the express 
limitations on the indemnification obligations set forth in subparagraph 
9(x) below) Tenant shall pay all costs, expenses and obligations of 
every kind relating to the Leased Property or this Lease which may arise 
or become due, including, without limitation: (i) Impositions, including 
any taxes payable by virtue of Landlord's receipt of amounts paid to or 
on behalf of Landlord in accordance with this subparagraph 3(h), but not 
including any Excluded Taxes; (ii) any Capital Adequacy Charges; (iii) 
any amount for which Landlord is or becomes liable with respect to the 
Permitted Encumbrances; and (iv) any costs incurred by Landlord 
(including Attorneys' Fees) because of Landlord's acquisition or 
ownership of the Leased Property or because of this Lease or the 
transactions contemplated herein.

     (i)  No Demand or Setoff.  The Base Rent and all Additional Rent 
shall be paid without notice or demand and without abatement, 
counterclaim, deduction, setoff or defense, except as expressly provided 
herein.

  4  Application of Insurance, Condemnation and Other Proceeds; Waiver 
of Insured Claims; Determination of Appraised Value.

     (a)  This Paragraph 4 shall govern the application of proceeds 
received by Landlord or Tenant during the Term from any third party (1) 
under any casualty insurance policy as a result of damage to the Leased 
Property, (2) as compensation for any restriction placed upon the use or 
development of the Leased Property or for the condemnation of the Leased 
Property or any portion thereof, or (3) because of any judgment, decree 
or award for injury or damage to the Leased Property; excluding, 
however, any funds paid to Landlord by Landlord's Parent or an Affiliate 
of Landlord or any Participant that is made to compensate Landlord for 
any losses Landlord may incur in connection with this Lease or the 
Leased Property.  Landlord and Tenant shall apply all insurance, 
condemnation and other proceeds described in the preceding sentence 
(including proceeds payable under any insurance policy covering the 
Leased Property which is maintained by Tenant) as follows:

       (i)  First, any such proceeds shall be used to reimburse Landlord 
for any costs and expenses, including Attorneys' Fees, incurred in 
connection with the collection of such proceeds.

       (ii)  Second, unless otherwise required by this Paragraph 4, such 
proceeds remaining after application in accordance with clause (a)(i) 
above (hereinafter, the "Remaining Proceeds") will be applied by 
Landlord as Qualified Payments.  However, pending a determination of 
whether Remaining Proceeds must be applied by Landlord to reimburse 
Tenant for the cost of repairs or restoration of the Leased Property 
pursuant to the following provisions, Landlord shall be entitled to hold 
any Remaining Proceeds as Escrowed Proceeds.   Until Remaining Proceeds 
are paid to Tenant as reimbursement for repairs to or restoration of the 
Lease Premises pursuant to this Paragraph 4 or applied as a Qualified 
Payment or as reimbursement to Landlord for costs incurred in connection 
with a Qualified Payment, Landlord shall keep the same as Escrowed 
Proceeds deposited in an interest bearing account, and all interest 
earned on such account shall be added to and made a part of such 
Escrowed Proceeds.

       (iii) Subject to the next clause (iv), after any taking by 
condemnation of all or any portion of the Leased Property or any 
casualty resulting in the diminution, destruction, demolition or damage 
to all or any portion of the Leased Property, either Landlord or Tenant 
may require a determination of whether Appraised Value immediately after 
such condemnation or casualty event is less than, equal to or greater 
than thirty percent (30%) of Stipulated Loss Value immediately after 
such condemnation or casualty event, and:

          (1)  If Appraised Value is greater than or equal to thirty 
percent (30%) of Stipulated Loss Value, then Landlord shall hold 
Remaining Proceeds as Escrowed Proceeds and apply them to reimburse 
Tenant for the actual cost of the repairs or restoration of the Leased 
Property.  Repairs or restoration for which Tenant shall be entitled to 
reimbursement pursuant to the preceding sentence shall include any 
repairs or restoration Tenant deems appropriate so long as the repairs 
or restoration return the Leased Property to a safe and secure condition 
and do not reduce its Appraised Value below thirty percent (30%) of 
Stipulated Loss Value.  Any Remaining Proceeds not used for such repairs 
or restoration shall, after Tenant notifies Landlord that they are not 
needed for repairs or restoration, be applied by Landlord as Qualified 
Payments.

          (2)  If Appraised Value is less than thirty percent (30%) of 
Stipulated Loss Value, then, either:

               (A)  Tenant must no later than the next Advance Date or 
Base Rental Date after such condemnation or casualty event (1) cause 
Stipulated Loss Value to be reduced to an amount no greater than three 
and one-third (3.33) times Appraised Value by authorizing Landlord's 
application of Remaining Proceeds as Qualified Payments and, if 
necessary to so reduce Stipulated Loss Value, by making additional 
payments to Landlord as Qualified Payments, and (2) do whatever is 
necessary to make the Leased Property safe and secure without further 
reducing its Appraised Value; or

               (B)  Tenant must elect no later than the next Advance 
Date or Base Rental Date after such condemnation or casualty event to 
terminate this Lease in accordance with Paragraph 2(b), and then Tenant 
or an Applicable Purchaser must purchase (and Landlord must sell) 
Landlord's interest in the Leased Property (even if Landlord can claim 
no interest of any value because of a total taking by eminent domain) in 
accordance with the Purchase Agreement, but for a net price to Landlord 
(when taken together with any additional payments made by Tenant 
pursuant to Paragraph 2(a)(ii) of the Purchase Agreement, in the case of 
a purchase by an Applicable Purchaser) of not less than Stipulated Loss 
Value, computed after the application of all Remaining Proceeds as 
Qualified Payments (and pending such purchase Tenant must do whatever is 
necessary to keep the Leased Property safe and secure); or 

               (C)  Tenant must promptly restore the Leased Property or 
the remainder thereof as necessary to raise its Appraised Value to no 
less than thirty percent (30%) of Stipulated Loss Value as of the date 
such restoration is complete and as necessary to make the Leased 
Property safe and secure.

                    Tenant's (and Landlord's) obligations under this 
clause (iii) with respect to any casualty or condemnation during the 
Term shall survive the expiration of the Term.

         (iv)  If any taking by condemnation of any portion of the 
Leased Property or any casualty resulting in the diminution, 
destruction, demolition or damage to any portion of the Leased Property 
shall reduce Appraised Value by less than $1,000,000 and shall result in 
Remaining Proceeds of less than $1,000,000, then so long as no Event of 
Default shall have occurred and be continuing Tenant shall be entitled 
to collect the Remaining Proceeds resulting therefrom.  Tenant shall 
apply any such Remaining Proceeds to the repair or restoration of the 
Leased Property to a safe and secure condition and to an Appraised Value 
of no less than thirty percent (30%) of Stipulated Loss Value in such 
manner as Tenant shall reasonably deem appropriate.

          (v)  As used herein, "Appraised Value" shall mean an amount 
not less than the fair market value of the Leased Property (or any 
applicable portion thereof) on the date in question as determined by 
Landlord and Tenant, or if Landlord and Tenant cannot agree, determined 
in accordance with the following procedure:

               (A)  Landlord and Tenant shall each, within ten (10) days 
after written notice from either to the other, select an appraiser.  If 
either Landlord or Tenant fails to select an appraiser within the 
required period, then the appraiser who has been timely selected shall 
conclusively determine the fair market value of the Leased Property (or 
applicable portion thereof) in accordance with this clause (v) within 
forty-five (45) days after his or her selection.

               (B)  Upon the selection of the two appraisers as provided 
above, such appraisers shall proceed to determine the fair market value 
of the Leased Property (or applicable portion thereof) in accordance 
with this clause (v).  Such appraisals shall be submitted in writing no 
later than forty-five (45) days after selection of the second appraiser.  
If the fair market value as determined by such appraisers is identical, 
such sum shall be Appraised Value.  In the event the lower appraisal is 
not lower than five percent (5%) below the higher appraisal, then 
Appraised Value shall be the sum of the two appraisal figures divided by 
two (2).  If either appraiser fails to timely submit his or her 
appraisal, the timely submitted appraisal shall be determinative of 
Appraised Value.

               (C)  In the event the lower appraisal is lower than five 
percent (5%) below the higher appraisal figure, then the two appraisers 
previously selected shall select a third appraiser.  The name of such 
appraiser shall be submitted at the same time the written appraisals are 
due.  Such third appraiser shall then review the previously submitted 
appraisals and select the one that, in his professional opinion, more 
closely reflects the fair market value of the Leased Property (or 
applicable portion thereof), such selection to be submitted in writing 
no later than ten (10) days after selection of the third appraiser.  
Such selection shall be determinative of Appraised Value.

               (D)  In making any such determination of fair market 
value, the appraisers shall assume that any improvements then located on 
the Leased Property (or applicable portion thereof) or under 
construction constitute the highest and best use, that Tenant will 
promptly complete all construction which this Lease obligates Tenant to 
complete and that neither this Lease nor the Purchase Agreement add any 
value to the Leased Property.  Each appraiser selected hereunder shall 
be an independent MAI-designated appraiser with not less than ten (10) 
years' experience in industrial real estate appraisal in Solano County, 
California and surrounding areas.

         (vi)  Notwithstanding the foregoing, following any Event of 
Default, Landlord shall be entitled to receive and collect any Remaining 
Proceeds and either, at the discretion of Landlord, hold such Remaining 
Proceeds as Escrowed Proceeds to be applied to the repair, restoration 
or replacement of the Leased Property in accordance with clause (b) 
below, or retain such Remaining Proceeds (net of collection costs, as 
set forth in clause (a)(i) above, and other appropriate deductions) as 
Qualified Payments.  Further, nothing contained in this Paragraph 4 
shall excuse Tenant from Tenant's obligation for completing all 
Construction Projects in accordance with the requirements of Paragraph 
6(b). 

     (b)  If, in accordance with any provision of this Paragraph 4, 
Remaining Proceeds are to be held by Landlord for reimbursement to 
Tenant of the cost of repair or restoration of the Leased Property: (a) 
Landlord will hold such Remaining Proceeds as Escrowed Proceeds in an 
interest bearing account as provided above and shall pay the same to 
Tenant upon completion of the applicable repair or restoration of the 
Leased Property and upon compliance by Tenant with such terms, 
conditions and requirements as may be reasonably imposed by Landlord, 
but in no such event shall Landlord be required to pay any Remaining 
Proceeds to Tenant in excess of the actual cost to Tenant of the 
applicable repair or restoration, it being understood that Landlord may 
retain any such excess as a Qualified Payment; and (b) Tenant, in 
accordance with the foregoing, will perform or cause to be performed the 
actual repair or restoration of the Leased Property to a safe and secure 
condition leaving the Leased Property with an Appraised Value of no less 
than thirty percent (30%) of Stipulated Loss Value upon completion of 
such repair or restoration.  In any event, Tenant will not be entitled 
to any abatement or reduction of the Base Rent or any other amount due 
hereunder except to the extent that such insurance or condemnation 
proceeds result in Qualified Payments which reduce Stipulated Loss Value 
as provided in the definitions set out above.

     (c)  Nothing herein contained shall be construed to prevent Tenant 
from obtaining a separate award from any condemning authority for a 
taking of Tenant's personal property or for moving expenses or business 
interruption, provided, such award is not combined with and does not 
reduce the award for any taking of the Leased Property, including 
Tenant's leasehold estate and any other interest therein.

     (d)  Landlord and Tenant each waive any right of recovery against 
the other, and the other's agents, officers, or employees, for any 
damage to the Leased Property or to the personal property situated from 
time to time in or on the Leased Property resulting from fire or other 
casualty covered by a valid and collectible insurance policy;  provided, 
however, that the waiver set forth in this subparagraph shall be 
effective insofar, but only insofar, as compensation for such damage or 
loss is actually recovered by the waiving party (net of costs of 
collection) under the policy notwithstanding the waivers set out in this 
paragraph.  Tenant shall cause the insurance policies required of Tenant 
by this Lease to be properly endorsed, if necessary, to prevent any loss 
of coverage because of the waivers set forth in this paragraph.  If such 
endorsements are not available, the waivers set forth in this paragraph 
shall be ineffective to the extent that such waivers would cause 
required insurance with respect to the Leased Property to be impaired.

  5  No Lease Termination.

     (a)  Status of Lease.  Except as expressly provided herein, this 
Lease shall not terminate, nor shall Tenant have any right to terminate 
this Lease, nor shall Tenant be entitled to any abatement of the Rent, 
nor shall the obligations of Tenant under this Lease be excused, for any 
reason whatsoever, including without limitation any of the following: 
(i) any damage to or the destruction of all or any part of the Leased 
Property from whatever cause, (ii) the taking of the Leased Property or 
any portion thereof by eminent domain or otherwise for any reason, (iii) 
the prohibition, limitation or restriction of Tenant's use of all or any 
portion of the Leased Property or any interference with such use by 
governmental action or otherwise, (iv) any eviction of Tenant or of 
anyone claiming through or under Tenant by paramount title or otherwise 
(provided, if Tenant is wrongfully evicted by Landlord or by any third 
party lawfully claiming through or under Landlord, other than Tenant or 
a third party claiming through or under Tenant, then Tenant will have 
the remedies described in Paragraph 16 below), (v) any default on the 
part of Landlord under this Lease or under any other agreement to which 
Landlord and Tenant are parties, (vi) the inadequacy in any way 
whatsoever of the design or construction of any improvements included in 
the Leased Property, it being understood that Landlord has not made and 
will not make any representation express or implied as to the adequacy 
thereof, or (vii) any other cause whether similar or dissimilar to the 
foregoing, any existing or future law to the contrary notwithstanding.  
It is the intention of the parties hereto that the obligations of Tenant 
hereunder shall be separate and independent of the covenants and 
agreements of Landlord, that the Base Rent and all other sums payable by 
Tenant hereunder shall continue to be payable in all events and that the 
obligations of Tenant hereunder shall continue unaffected, unless the 
requirement to pay or perform the same shall have been terminated or 
limited pursuant to an express provision of this Lease.  However, 
nothing in this Paragraph shall be construed as a waiver by Tenant of 
any right Tenant may have at law or in equity to (i) recover monetary 
damages for any default under this Lease by Landlord that Landlord fails 
to cure within the period provided in Paragraph 16, (ii) injunctive 
relief in case of the violation, or attempted or threatened violation, 
by Landlord of any of the express covenants, agreements, conditions or 
provisions of this Lease (including the confidentiality provisions set 
forth in Paragraph 23 below), or (iii) a decree compelling performance 
of any of the express covenants, agreements, conditions or provisions of 
this Lease.

     (b)  Waiver By Tenant.  Without limiting the foregoing, Tenant 
waives to the extent permitted by Applicable Laws, except as otherwise 
expressly provided herein, all rights to which Tenant may now or 
hereafter be entitled by law (including any such rights arising because 
of any implied "warranty of suitability" or other warranty under 
Applicable Laws) (i) to quit, terminate or surrender this Lease or the 
Leased Property or any part thereof or (ii) to any abatement, 
suspension, deferment or reduction of the Base Rent or any other sums 
payable under this Lease.

  6  Construction Allowance.

     (a)  Advances; Outstanding Construction Allowance.

          (i)  Subject to the conditions set forth below, Landlord shall 
make advances (herein called "Construction Advances") on Advance Dates 
from time to time as requested by Tenant to reimburse Tenant for the 
cost of Construction Projects or to pay Commitment Fees or Agency Fees 
then due.  As used herein, references to the "Outstanding Construction 
Allowance" shall mean the difference on the date in question (but not 
less than zero) of (A) the total Construction Advances made by Landlord 
on or prior to the date in question, less (B) any Qualified Payments 
received on or prior to the date in question; provided, that Landlord 
will not be under any obligation to readvance any portion of the 
Construction Allowance repaid by Qualified Payments.  Notwithstanding 
the foregoing, if for any reason Stipulated Loss Value (and thus the 
Outstanding Construction Allowance included as a component thereof) must 
be determined under this Lease as of any date between Advance Dates, the 
Outstanding Construction Allowance determined on such date shall equal 
the Outstanding Construction Allowance on the immediately preceding 
Advance Date computed in accordance with the preceding sentence, plus 
Carrying Costs (if any) accruing on and after such preceding Advance 
Date to but not including the date in question.

         (ii)  Charges accruing at the Effective Rate (herein 
collectively called "Carrying Costs") for each Construction Period 
ending on or prior to the Base Rental Commencement Date will be added to 
(and thereafter be included in) the Outstanding Construction Allowance 
on the last day of each such Construction Period (i.e., on the Advance 
Date upon which such Construction Period ends).  The amount of Carrying 
Costs for each such Construction Period shall be equal to (A) Stipulated 
Loss Value (including Carrying Costs added with respect to every 
previous Construction Period, if any) as of the first day of such 
Construction Period, times (B) the Effective Rate with respect to such 
Construction Period, times (C) the number of days in such Construction 
Period, divided by (D) 360; provided, however, that because the 
Construction Allowance available under this Lease is limited to the 
Maximum Construction Allowance, Carrying Costs added to the Outstanding 
Construction Allowance on the Base Rental Commencement Date shall not 
exceed the amount that can be added without causing the Outstanding 
Construction Allowance to exceed the Maximum Construction Allowance.

         (iii)  For purposes of determining the Effective Rate to be 
used in the calculation of Carrying Costs which will accrue during the 
first short Construction Period ending on January 2, 1996, the 
"comparable period" referred to in clause (iii) of the definition of 
LIBOR above shall be thirty days.  If, however, any Breakage Costs (as 
defined below) are incurred in connection with the use of such an 
Effective Rate for the first Construction Period, the Breakage Costs 
will be included in Carrying Costs added to the Outstanding Construction 
Allowance at the end of the first Construction Period.  "Breakage Costs" 
means losses, if any,  incurred or sustained by Landlord's Parent and 
Participants with respect to prior Funding Advances that they would not 
have incurred or sustained but for a decline on the first Advance Date, 
before the end of the LIBOR period used to compute LIBOR for the first 
short Construction Period, in the LIBOR component of the Effective Rate.  
Any determination by Landlord's Parent of Breakage Costs shall, in the 
absence of clear and demonstrable error, be conclusive and binding upon 
Landlord and Tenant.

     (b)  Construction Projects.

          (i)  Preconstruction Approvals.  Prior to the execution of 
this Lease, Tenant submitted and obtained Landlord's approval of plans 
or renderings for, a construction budget for, and descriptions of the 
initial Construction Project which Tenant expects to construct with the 
Construction Allowance.  Except as provided below in this subparagraph, 
Tenant shall submit and obtain Landlord's written approval of plans or 
renderings for any subsequent Construction Project prior to commencement 
of the subsequent Construction Project.  Landlord may disapprove of such 
plans or other items if, but only if, Landlord believes in good faith 
that the Construction Project proposed by Tenant will (1) fail to 
satisfy the requirements set forth in subparagraph 6(b)(iv), (2) change 
the general character of the Leased Property from that needed to 
accommodate the uses permitted by subparagraph 8(a) or (3) cause Tenant 
or the Leased Property to violate some other express provision of this 
Lease; but no approval given by Landlord in connection with any 
Construction Project, prior to or after the date hereof, shall 
constitute a waiver of subparagraph 6(b)(iv) or of any other provision 
of this Lease.  Any items hereafter submitted by Tenant to satisfy this 
subparagraph shall be sufficiently detailed to allow Landlord to make a 
reasonable determination of whether the applicable Construction Project 
will satisfy subparagraph 6(b)(iv), but need not include all detailed 
construction specifications and drawings of the work to be included in 
the Construction Project.  All Construction Projects commenced by 
Tenant, including the initial Construction Project which is described in 
Schedule 3, and all Construction Documents executed or adopted by Tenant 
in connection therewith, must be substantially consistent with the plans 
or other items heretofore or hereafter submitted to and approved by 
Landlord as described above in this subparagraph, except to the extent 
otherwise provided by any Scope Changes approved as described below.  
Before commencing any Construction Project subsequent to the initial 
Construction Project, Tenant shall notify Landlord if Tenant believes 
that, upon completion of such subsequent Construction Project, there 
will be a substantial likelihood that the Leased Property will have an 
Appraised Value of less than 30% of Stipulated Loss Value.
 
         (ii)  Scope Changes.  Before making a Scope Change to any 
Construction Project, Tenant shall provide to Landlord a reasonably 
detailed written description of the Scope Change, a revised construction 
budget (only if such Scope Change will require an increase in the 
existing construction budget) and a copy of any changes to the drawings, 
plans and specifications for the Improvements required in connection 
therewith, all of which must be approved in writing by Landlord (or by 
any construction representative appointed by Landlord from time to time) 
before the Scope Change is implemented.  Landlord may disapprove of any 
Scope Change if, but only if, Landlord believes in good faith that the 
Construction Project proposed by Tenant, as modified by the Scope 
Change, will (1) fail to satisfy the requirements set forth in 
subparagraph 6(b)(iv), (2) change the general character of the Leased 
Property from that needed to accommodate the uses permitted by 
subparagraph 8(a) or (3) cause Tenant or the Leased Property to violate 
some other express provision of this Lease; but Landlord's approval 
shall not constitute a waiver of subparagraph 6(b)(iv) or of any other 
provision of this Lease.

        (iii)  Responsibility for Construction.  Tenant shall have sole 
responsibility for contracting for and administering all Construction 
Projects, it being understood that Landlord's obligation with respect to 
Construction Projects shall be limited to the making of advances under 
and subject to the conditions set forth in this Paragraph 6.  No 
contractor or other third party shall be entitled to require Landlord to 
make advances as a third party beneficiary of this Lease or otherwise.  
Notwithstanding delays beyond Tenant's control, and even if the 
Construction Allowance is not sufficient to pay for completion of any 
Construction Project, Tenant warrants that on the Designated Payment 
Date under the Purchase Agreement it shall have caused the initial 
Construction Project and any subsequent Construction Projects which are 
commenced during the Term to be completed in a good and workmanlike 
manner, substantially in accordance with Applicable Laws, and otherwise 
in compliance with the provisions of this Lease, unless Tenant or an 
Applicable Purchaser has purchased the Leased Property pursuant to the 
Purchase Agreement for a net price to Landlord (when taken together with 
any additional payments made by Tenant pursuant to Paragraph 2(a)(ii) of 
the Purchase Agreement, in the case of a purchase by an Applicable 
Purchaser) of not less than Stipulated Loss Value.

         (iv)  Value Added.   Each Construction Project, upon completion 
and taken as a whole, must enhance the value of the Leased Property by 
an amount commensurate with the Construction Advances made for such 
Construction Project, and no Construction Project may significantly 
reduce the fair market value of the Property; however:

               (1)  this subparagraph 6(b)(iv) will not preclude Tenant 
from obtaining Construction Advances for soft costs (such as 
architectural fees and design and permitting costs), Tenant's internal 
labor costs, demolition costs or other costs that do not, individually, 
add value to the Leased Property but that are incurred in connection 
with a Construction Project which will in the aggregate satisfy this 
subparagraph 6(b)(iv);

               (2)  to address any concerns Landlord may express about 
Tenant's ability to satisfy this subparagraph 6(b)(iv) for a 
Construction Project, Tenant may by a written notice to Landlord 
stipulate a maximum amount of Construction Advances that Landlord will 
be required to make for such Construction Project, in which case 
Landlord shall not be required to make Construction Advances for such 
project in excess of the amount so stipulated;  

               (3)  if Landlord invokes this subparagraph 6(b)(iv) as 
justification for disapproving of a Construction Project (or Scope 
Change) or for declining to provide Construction Advances for a 
Construction Project, then Tenant may satisfy this subparagraph 6(b)(iv) 
by (A) stipulating a maximum amount of Construction Advances that 
Landlord will be required to make for such Construction Project, and (B) 
establishing that Appraised Value of the Leased Property (determined in 
accordance with the procedures outlined in Paragraph 4) will be no less 
than 30% of Stipulated Loss Value upon completion of the Construction 
Project and after Landlord provides Construction Advances equal to the 
maximum so stipulated;

               (4)  further, if Tenant ever does satisfy this 
subparagraph 6(b)(iv) for a particular Construction Project by 
establishing an Appraised Value of no less than 30% of Stipulated Loss 
Value as described in the preceding clause (3), Landlord shall have no 
further right, absent a subsequent Scope Change to such Construction 
Project, to invoke this subparagraph 6(b)(iv) as justification for 
disapproving of such Construction Project or for withholding 
Construction Advances requested within the limit of the maximum 
Construction Advances stipulated by Tenant.


          (v)  Estoppel Letters Required.  Upon the execution of each 
general construction contract for the initial Construction Project and 
for any subsequent Construction Project expected to cost in excess of 
$10,000,000, Tenant shall cause the contractor thereunder to execute and 
deliver to Landlord an estoppel letter in the form of Exhibit C attached 
hereto.  Tenant shall also cause the architect and engineer under any 
material architectural or engineering contract for such a Construction 
Project to execute and deliver to Landlord an estoppel letter in the 
form of Exhibit D attached hereto. Landlord shall consider in good faith 
any changes to the estoppel letter forms attached hereto that Tenant may 
reasonably request for a particular Construction Project, provided the 
requested changes do not impair Landlord's rights or create or increase 
any liability Landlord may have in connection with the Construction 
Project.

         (vi)  Advances Not a Waiver.  No funding of Construction 
Advances and no failure of Landlord to object to any Construction 
Project proposed or constructed by Tenant shall constitute a waiver by 
Landlord of the requirements contained in this subparagraph 6(b).

     (c)  Conditions to Construction Advances.  Landlord's obligation to 
make Construction Advances from time to time under this Paragraph 6 
shall be subject to the following terms and conditions, all of which are 
intended for the sole benefit of Landlord:

          (i)  Prior Notice.  Tenant must make a request in 
substantially the form attached to this Lease as Exhibit E for any 
Construction Advance at least ten (10) Business Days prior to the 
Advance Date upon which the advance is to be paid.  Landlord shall 
consider in good faith any changes to the Construction Advance request 
forms attached hereto that Tenant may reasonably request for a 
particular Construction Project, provided the requested changes do not 
impair Landlord's rights or create or increase any liability Landlord 
may have in connection with the Construction Project.

         (ii)  Amount of the Advances.  No Construction Advance shall 
exceed the lesser of:

                a) the Maximum Construction Allowance, less the then 
Outstanding Construction Allowance (computed after adding any Carrying 
Costs accrued for the month ending on the Advance Date upon which such 
Construction Advance is to be made); or 

                b) (1) the actual costs and expenses previously incurred 
or paid by Tenant for the preparation, negotiation and execution of this 
Lease (other than expenses already included in Transaction Expenses), 
for Construction Projects (including "soft costs"), for Agency Fees not 
included in Transaction Expenses or for Commitment Fees, less (2) the 
sum of the portion of the Initial Funding Advances provided for 
construction of Improvements (or site work on the Land) as described in 
the definition of Initial Funding Advances, plus all Construction 
Advances made under this Paragraph 6 to Tenant as reimbursement for such 
costs and expenses.

     No Construction Advance (other than the final Construction Advance) 
shall be requested for an amount less than the lesser of (A) the maximum 
advance that may be required of Landlord under the preceding sentence, 
and (B) $500,000. 

        (iii)  Insurance.  Tenant shall have obtained and provided 
certificates (or, in the case of clause a) below, title policies or 
binders) reasonably satisfactory to Landlord evidencing insurance 
covering the Leased Property as follows (in addition to the liability 
insurance required under subparagraph 9(y) below):

                a)  Title Insurance.  An owner's title insurance policy 
(or binder committing the applicable title insurer to issue an owner's 
title insurance policy, without the payment of further premiums) in the 
amount of $125,000,000, in form and substance reasonably satisfactory to 
Landlord, written by Chicago Title Insurance Company or one or more 
other title insurance companies reasonably satisfactory to Landlord and 
insuring Landlord's ownership of fee title to the Leased Property, 
including any new Improvements constructed by Tenant; and

                b)  Builder's Risk Insurance.  Builder's Completed Value 
Risk and such other hazard insurance as Landlord may require against all 
risks of physical loss (including collapse and transit coverage, but not 
including earthquake coverage) with deductibles not to exceed 
$1,000,000, such insurance to be in amounts sufficient to cover the 
total value of all Improvements under construction and to be maintained 
in full force and effect at all times until completion of the initial 
Construction Project or any subsequent Construction Projects. 

         (iv)  Progress of Construction.  Each Construction Project 
which has commenced but not yet been completed shall be progressing 
without any significant continuing interruption in a good and 
workmanlike manner and substantially in accordance with Applicable Laws 
and the requirements of this Lease, and Tenant shall have corrected or 
be diligently pursuing the correction of any significant defect in the 
construction thereof.

          (v)  Evidence of Costs and Expenses to be Reimbursed.  To the 
extent contemplated by the Construction Advance request forms attached 
as Exhibit E and described in subparagraph 6(c)(i), or otherwise 
reasonably required by Landlord at the time a Construction Advance is to 
be made, Tenant shall have submitted invoices, requests for payment from 
contractors and other evidence that all costs and expenses for which 
Tenant requests reimbursement constitute actual costs and expenses 
incurred by Tenant for a Construction Project.

         (vi)  No Event of Default.  No Event of Default shall have 
occurred and be continuing under this Lease.

        (vii)  No Sale of Landlord's Interest.  No sale of Landlord's 
interest in the Leased Property shall have occurred pursuant to the 
Purchase Agreement.

       (viii)  Certificate of No Default and Other Matters. Landlord 
shall have received, together with the notice requesting the 
Construction Advance described in clause (i) above, a current 
certificate of an officer of Tenant in the form included in Exhibit F 
(a) certifying that no Event of Default has occurred and is continuing, 
(b) certifying that the representations and warranties contained herein 
are true and correct in all material respects on and as of the date of 
such certificate as though made on and as of such date, subject only to 
such exceptions as may be disclosed therein and as are acceptable to 
Landlord, (c) certifying that each Construction Project which has 
commenced but not yet been completed is progressing without any 
significant continuing interruption in a good and workmanlike manner and 
substantially in accordance with the requirements of this Lease and all 
Applicable Laws and that Tenant has corrected or is diligently pursuing 
the correction of any significant defect in the construction thereof, 
(d) certifying that all costs and expenses for which Tenant is 
requesting reimbursement by the Construction Advance constitute actual 
costs and expenses incurred by Tenant for a Construction Project, and 
(e) certifying that, to the knowledge of Tenant, any liens then being 
asserted against the Leased Property by general contractors or other 
parties who have filed a statutory Preliminary Notice to preserve their 
right to a mechanic's or materialman's lien against the Leased Property 
(collectively, "Potential Lien Claimants") do not in the aggregate 
secure or allegedly secure more that $5,000,000 of claims.  (As used in 
this subparagraph a lien will be considered as "being asserted" if a 
claim of lien relating thereto shall have been recorded and not 
discharged by payment or settlement.)  Further, a copy of the 
certificate required by this clause shall have been furnished by Tenant 
to each of the Participants, and the certificate shall be true and 
correct.  Without limiting the foregoing, Landlord may decline to 
advance any amount when liens are being asserted against any part of or 
interest in the Leased Property that in the aggregate secure or 
allegedly secure more that $5,000,000 of claims by Potential Lien 
Claimants, regardless whether any such liens have caused an Event of 
Default to occur hereunder or are being contested by Tenant as permitted 
by subparagraph 9(o).

         (ix)  Payments by Participants.  None of the Participants or 
their successors under their participation agreements with Landlord 
shall have failed to advance to Landlord their pro rata shares of the 
Construction Advance being requested.  However, any such failure shall 
excuse Landlord's obligation to provide the Construction Advance 
requested only to the extent of the funds that the applicable 
Participant or Participants should have advanced (but did not advance) 
to Landlord, and in the event of any such failure:

                a)  Landlord will immediately notify Tenant if any 
Participant refuses or fails to advance its pro rata share of any 
Construction Advance, but Landlord will not in any event be liable to 
Tenant for Landlord's failure to do so.

                b)  Landlord will, to the extent possible, postpone 
reductions of Construction Advances because of the failure by any one or 
more Participants ("Nonfunding Participants") to make required advances 
under their participation agreements with Landlord (a "Participant 
Default") by adjusting (and readjusting from time to time, as required) 
the funding "Percentages" of other Participants, and by requesting the 
other Participants to make advances to Landlord on the basis of such 
adjusted Percentages, in each case as provided in the participation 
agreements between the Participants and Landlord; however, so long as a 
Participant Default continues, no Construction Advance shall be required 
that would cause the Outstanding Construction Allowance to exceed (a) 
the Maximum Construction Allowance available under this Lease, less (b) 
all amounts that should have been, but because of a continuing 
Participant Default have not been, advanced by any one or more of the 
Participants to Landlord under their participation agreements with 
Landlord with respect to Construction Advances. 

                c)  Further, after a Participant Default, and so long as 
no Event of Default has occurred and is continuing, Landlord shall do 
the following as reasonably requested by Tenant, provided that nothing 
in this provision shall require Landlord to take any action that would 
violate Applicable Laws, that would constitute a breach of Landlord's 
obligations under the participation agreements with the Participants, or 
that would require Landlord to waive any rights or remedies it has under 
this Lease, the Purchase Agreement or Landlord's other agreements with 
Tenant concerning the Leased Property:

                      (1)  Landlord shall promptly make a written demand 
upon the Nonfunding Participants for the cure of the Participant 
Default.

                      (2)  Landlord shall, to the extent Landlord has 
the right to do so under Landlord's participation agreements with the 
Participants, decline to allow the Nonfunding Participants to exercise 
voting, consent or notification rights under the participation 
agreements.

                      (3)  Landlord shall not unreasonably withhold its 
approval for the substitution of any new participant proposed by Tenant 
for Nonfunding Participants, if (A) the proposed substitution does not 
require Landlord to waive rights against the Nonfunding Participants, 
(B) the new participant will agree (by executing a participation 
agreement that is consistent with and substantially similar to the 
participation agreements that Landlord has entered into with the 
Participants and that is otherwise in form reasonably satisfactory to 
Landlord and Tenant) to provide funds to replace the payments that would 
otherwise be required of the Nonfunding Participants with respect to 
future Construction Advances, (C) the new participant (or Tenant) 
provides the funds (if any) needed to terminate the Nonfunding 
Participants' rights to receive payments of "Net Cash Flow" (as defined 
in the participation agreements between with Landlord and the 
Participants) that Landlord will be required to pay the new participant 
under the terms of the substitution reasonably proposed by Tenant, (D) 
the new participant (or Tenant) provides and agrees in writing to 
provide funds needed to reimburse Landlord for any and all Losses 
incurred by Landlord in connection with or because of the substitution 
of the new participant for the Nonfunding Participants, including the 
cost of preparing, negotiating and executing a new participation 
agreement between Landlord and the new participant and including any 
cost of defending and paying any claim asserted by Nonfunding 
Participants because of the substitution (but not including any 
liability of Landlord to the Nonfunding Participants for damages caused 
by Landlord's bad faith or gross negligence in the performance of 
Landlord's obligations to the Nonfunding Participants), (E) the 
obligations of Landlord to the new participant per dollar of the new 
participant's "investment" (it being understood that such investment 
will be computed in a manner consistent with the examples set forth in 
Exhibit A of the participation agreements between Landlord and the 
Participants, but net of reimbursements to Landlord under clause (D) 
preceding) shall not exceed the obligations per dollar of investment by 
the Nonfunding Participants that Landlord would have had to the 
Nonfunding Participants if there had been no Participant Default, and 
(F) the new participant shall be a reputable financial institution 
having a net worth of no less than seven and one half percent (7.5%) of 
total assets and total assets of no less than $10,000,000,000.00 (all 
according to then recent audited financial statements).

          (x)  Execution of Participation Agreements With Participants.  
All of the Persons listed in Schedule 1 shall have entered into 
participation agreements with Landlord which shall cause them to qualify 
as Participants hereunder.  Any such participation agreement executed 
after this Lease is executed shall be subject to Tenant's prior 
approval, and Landlord shall promptly furnish Tenant with a copy of any 
such agreement. 

  7  Purchase Agreement and Environmental Indemnity Agreement.  Tenant 
acknowledges and agrees that nothing contained in this Lease shall 
limit, modify or otherwise affect any of Tenant's obligations under the 
Purchase Agreement or the Environmental Indemnity Agreement, which 
obligations, to the maximum extent possible, shall be deemed to be 
separate, independent and in addition to, and not in lieu of, the 
obligations set forth herein.  In the event of any inconsistency between 
the terms and provisions of the Purchase Agreement or the Environmental 
Indemnity Agreement and the terms and provisions of this Lease, the 
terms and provisions of the Purchase Agreement or Environmental 
Indemnity Agreement shall control.

  8  Use and Condition of Leased Property.

     (a)  Use.  Subject to the Permitted Encumbrances and the terms 
hereof, Tenant may use, occupy and operate the Leased Property during 
the Term so long as no Event of Default occurs hereunder, but only for 
the following purposes and other lawful purposes incidental thereto:

          (i)  construction, development, testing and validation of 
Construction Projects;

         (ii)  biotechnology/pharmaceutical manufacturing;

        (iii)  support functions for such manufacturing uses, including 
processing, research, laboratory, development, distribution, warehousing 
or similar uses;

         (iv)  administrative and office space; and

          (v)  cafeteria, library and facilities that Tenant may provide 
to its employees.

     (b)  Condition.  Tenant accepts the Leased Property (and will 
accept the same upon any purchase of the Landlord's interest therein) in 
its present state, AS IS, and without any representation or warranty, 
express or implied, as to the condition of such property or as to the 
use which may be made thereof.  Tenant also accepts the Leased Property 
without any representation or warranty, express or implied, by Landlord 
regarding the title thereto or the rights of any parties in possession 
of any part thereof, except as set forth in subparagraph 10(a).  
Landlord shall not be responsible for any latent or other defect or 
change of condition in the Land, Improvements, fixtures and personal 
property forming a part of the Leased Property, and the Rent hereunder 
shall in no case be withheld or diminished because of any latent or 
other defect in such property, any change in the condition thereof or 
the existence with respect thereto of any violations of Applicable Laws.  
Further, though Tenant may obtain from third parties any facilities or 
services to which Tenant is entitled by reason of the assignment and 
lease of Personal Property set forth on page 2 of this Lease, Landlord 
shall not itself be required to furnish to Tenant any facilities or 
service of any kind, such as, but not limited to, water, steam, heat, 
gas, hot water, electricity, light or power.

     (c)  Consideration for and Scope of Waiver.  The provisions of 
subparagraph 8(b) above have been negotiated by the Landlord and Tenant 
after due consideration for the Rent payable hereunder and are intended 
to be a complete exclusion and negation of any representations or 
warranties of the Landlord, express or implied, with respect to the 
Leased Property that may arise pursuant to any law now or hereafter in 
effect, or otherwise.  However, such exclusion of representations and 
warranties by Landlord is not intended to impair any representations or 
warranties made by other parties, including Seller, the benefit of which 
may pass to Tenant during the Term because of the definition of Personal 
Property and Leased Property above.

  9  Other Representations, Warranties and Covenants of Tenant.  Tenant 
represents, warrants and covenants as follows:

     (a)  Financial Matters.  Tenant is solvent and has no outstanding 
liens, suits, garnishments or court actions which could render Tenant 
insolvent.  There has not been filed by or, to Tenant's knowledge, 
against Tenant a petition in bankruptcy or a petition or answer seeking 
an assignment for the benefit of creditors, the appointment of a 
receiver, trustee, custodian or liquidator with respect to Tenant or any 
significant portion of Tenant's property, reorganization, arrangement, 
rearrangement, composition, extension, liquidation or dissolution or 
similar relief under the federal Bankruptcy Code or any state law.  (As 
used in this Lease, "Tenant's knowledge" means the present actual 
knowledge (with due investigation) of Daniel Spiegelman and Marty Glick 
and, as to matters concerning the Leased Property only, James Panek and 
George Mackey, all current employees of Tenant.  However, to the extent 
Tenant's knowledge after the date hereof may become relevant hereunder 
or under any certificate or other notice provided by Tenant to Landlord 
in connection with this Lease, "Tenant's knowledge" shall include the 
then actual knowledge of other employees of Tenant (if any) that have 
assumed responsibilities of the current employees listed in the 
preceding sentence or that have replaced such current employees.  None 
of the employees of Tenant whose knowledge is now or may hereafter be 
relevant shall be personally liable for the representations or 
warranties of Tenant made herein.)  The financial statements and all 
financial data heretofore delivered to Landlord relating to Tenant are 
true, correct and complete in all material respects.  No material 
adverse change has occurred in the financial position of Tenant as 
reflected in Tenant's financial statements covering the fiscal period 
ended September 30, 1995.

     (b)  The Contract and Other Development Contracts.  Except to the 
extent required of Landlord under subparagraph 10(b), Tenant shall 
satisfy the surviving obligations, if any, of the "Buyer" (as the term 
"Buyer" is used in the Contract) under the Contract and under all other 
documents to which Landlord has become bound or subject because of 
Landlord's acceptance of the assignment of the Contract or ownership of 
the Leased Property, including without limitation the Development 
Contracts listed in Schedule 2 attached hereto.  Tenant agrees to 
indemnify, defend and hold Landlord harmless from and against any and 
all Losses imposed on or asserted against or incurred by Landlord at any 
time and from time to time by reason of, in connection with or arising 
out of any obligations imposed by the Contract or the other Development 
Contracts.  The indemnity set out in this subparagraph shall apply even 
if the subject of the indemnification is caused by or arises out of the 
negligence of Landlord; provided, such indemnity shall not apply to 
Losses proximately caused by (and attributed by any applicable 
principles of comparative fault to) the Active Negligence, gross 
negligence or willful misconduct of Landlord, its Affiliates, agents or 
employees.  Because Tenant hereby assumes and agrees to satisfy all 
surviving obligations of the Buyer under the Contract and any other 
obligations imposed upon Landlord by reason of the Contract or the other 
Development Contracts, no failure by Landlord to take any action 
required by the Contract or the other Development Contracts (save and 
except any actions required of Landlord under subparagraph 10(b) below) 
shall, for the purposes of this indemnity, be deemed to be caused by the 
Active Negligence, gross negligence or willful misconduct of Landlord, 
its Affiliates, agents or employees.  The foregoing indemnity is in 
addition to the other indemnities set out herein and shall not terminate 
upon the closing of any sale of Landlord's interest in the Leased 
Property pursuant to the provisions of the Purchase Agreement or the 
termination of this Lease.

     (c)  No Default or Violation.  The execution, delivery and 
performance by Tenant of this Lease and the Purchase Agreement do not 
and will not constitute a breach or default under any other material 
agreement or contract to which Tenant is a party or by which Tenant is 
bound or which affects the Leased Property or which affects Tenant's 
use, occupancy or operation of the Leased Property or any part thereof 
and do not, to the knowledge of Tenant, violate or contravene any law, 
order, decree, rule or regulation to which Tenant is subject.  Further, 
such execution, delivery and performance by Tenant will not result in 
the creation or imposition of (or the obligation to create or impose) 
any lien, charge or encumbrance on, or security interest in, Tenant's 
property pursuant to the provisions of any of the foregoing in any 
respect which would have a material adverse effect upon the properties, 
assets, operations or businesses of Tenant and its Subsidiaries, taken 
as a whole.

     (d)  Compliance with Covenants and Laws.  To Tenant's knowledge, 
the intended use of the Leased Property by Tenant complies, or will 
comply after Tenant obtains readily available permits, in all material 
respects with all applicable restrictive covenants, zoning ordinances 
and building codes, flood disaster laws, applicable health, safety and 
environmental laws and regulations, the Americans with Disabilities Act 
and other laws pertaining to disabled persons, and all other applicable 
laws, statutes, ordinances, rules, permits, regulations, orders, 
determinations and court decisions (all of the foregoing are herein 
sometimes collectively called "Applicable Laws").  Tenant has obtained 
or will during the Term obtain on a timely basis all utility, building, 
health and operating permits as may be required for Tenant's use of the 
Leased Property during the Term by any governmental authority or 
municipality having jurisdiction over the Leased Property.

     (e)  Environmental Representations.  To Tenant's knowledge and 
except as otherwise disclosed in the Environmental Report, as of the 
date hereof: (i) no Hazardous Substances Activity (other than Permitted 
Hazardous Substance Use by Tenant) has occurred prior to the date of 
this Lease; (ii) neither Tenant nor any prior owner or operator of the 
Leased Property has reported or been required to report any release of 
any Hazardous Substances on or from the Leased Property pursuant to any 
Environmental Law; (iii) neither Tenant nor any prior owner or operator 
of the Leased Property has received any warning, citation, notice of 
violation or other communication regarding a suspected or known material 
release or discharge of Hazardous Substances on or from the Leased 
Property or regarding any significant  continuing or allegedly 
continuing violation of Environmental Laws concerning the Leased 
Property from any federal, state or local agency; and (iv) none of the 
following are located on the Leased Property: asbestos; urea 
formaldehyde foam insulation; transformers or other equipment which 
contain dielectric fluid containing levels of polychlorinated biphenyls 
in excess of fifty (50) parts per million; any other Hazardous 
Substances other than Permitted Hazardous Substances; or any underground 
storage tank or tanks.  Further, Tenant represents that to the best of 
its knowledge the Environmental Report is not misleading or inaccurate 
in any material respect.

     (f)  No Suits.  Other than as previously disclosed in Tenant's most 
recent 10-K filings with the Securities and Exchange Commission (copies 
of which have been delivered to Landlord), there are no judicial or 
administrative actions, suits, proceedings or investigations pending or, 
to Tenant's knowledge, threatened that are reasonably likely to affect 
Tenant's intended use of the Leased Property or the validity, 
enforceability or priority of this Lease, or Tenant's use, occupancy and 
operation of the Leased Property or any part thereof, and Tenant is not 
in default with respect to any order, writ, injunction, decree or demand 
of any court or other governmental or regulatory authority that could 
materially and adversely affect the business or assets of Tenant and its 
Subsidiaries taken as a whole or Tenant's use, occupancy or operation of 
the Leased Property.  No condemnation or other like proceedings are 
pending or, to Tenant's knowledge, threatened against the Leased 
Property.

     (g)  Condition of Property.  Adequate provisions have been made, or 
during the Term adequate provision will be made by Tenant or Tenant's 
Agents (pursuant to, without limitation, the Development Contracts), for 
any existing or planned Improvements (other than grading or other site 
work) to be served by electric, gas, storm and sanitary sewers, sanitary 
water supply, telephone and other utilities and by streets, alleys and 
easements necessary to serve such Improvements.  Upon completion of the 
initial Construction Project, the Leased Property will be in a condition 
satisfactory for its use and occupancy as intended under this Lease.  No 
part of the Real Property is within an area identified by the Secretary 
of Housing and Urban Development as an area having special flood 
hazards.

     (h)  Organization.  Tenant is duly incorporated and legally 
existing under the laws of the State of Delaware and is duly qualified 
to do business in the State of California.  Tenant has all requisite 
power and has procured or will procure on a timely basis all 
governmental certificates of authority, licenses, permits, 
qualifications and other documentation required to lease and operate the 
Leased Property.  Tenant has the corporate power and adequate authority, 
rights and franchises to own Tenant's property and to carry on Tenant's 
business as now conducted and is duly qualified and in good standing in 
each state in which the character of Tenant's business makes such 
qualification necessary (including, without limitation, the State of 
California) or, if it is not so qualified in a state other than 
California, such failure does not have a material adverse effect on the 
properties, assets, operations or businesses of Tenant and its 
Subsidiaries, taken as a whole.

     (i)  Enforceability.  The execution, delivery and performance of 
this Lease and the Purchase Agreement by Tenant are duly authorized, are 
not in contravention of or conflict with any term or provision of 
Tenant's articles of incorporation or bylaws and do not, to Tenant's 
knowledge, conflict with any Applicable Laws or require the consent or 
approval of any governmental body or other regulatory authority that has 
not heretofore been obtained; provided, some consents or approvals which 
are readily obtainable and which are required for Tenant's performance 
hereunder (for example, building permits required for construction of 
the initial Construction Project) may not have been heretofore obtained, 
but Tenant shall obtain such consents or approvals as required in 
connection with its performance of this Lease.  This Lease and the 
Purchase Agreement are valid, binding and legally enforceable 
obligations of Tenant except as such enforcement is affected by 
bankruptcy, insolvency and similar laws affecting the rights of 
creditors, generally, and equitable principles of general application.

     (j)  Not a Foreign Person.  Tenant is not a "foreign person" within 
the meaning of Sections 1445 and 7701 of the Code (i.e., Tenant is not a 
non-resident alien, foreign corporation, foreign partnership, foreign 
trust or foreign estate as those terms are defined in the Code and 
regulations promulgated thereunder).

     (k)  Omissions.  None of Tenant's representations or warranties 
contained in this Lease or in any other agreement between Tenant and 
Landlord relating to the Leased Property or in any Tenant certificate 
furnished to Landlord by or on behalf of Tenant in connection with the 
Leased Property contains any untrue statement of a material fact or 
omits a material fact necessary in order to make the statements 
contained herein or therein (when taken in their entireties) not 
misleading.

     (l)  Existence.  During the Term, Tenant shall continuously 
maintain its existence and its qualification to do business in the State 
of California, and Tenant will not make any significant change in the 
nature of the business of Tenant and its Subsidiaries, taken as a whole, 
as presently conducted.

     (m)  Tenant Taxes.  During the Term, Tenant shall comply with all 
applicable tax laws and pay before the same become delinquent all taxes 
imposed upon it or upon its property where the failure to so comply or 
so pay would have a material adverse effect on the financial condition 
or operations of Tenant and its Subsidiaries on a consolidated basis; 
except that Tenant may in good faith by appropriate proceedings contest 
the validity, applicability or amount of any such taxes and pending such 
contest Tenant shall not be deemed in default under this subparagraph if 
(1) Tenant diligently prosecutes such contest to completion in an 
appropriate manner, and (2) Tenant promptly causes to be paid any tax 
adjudged by a court of competent jurisdiction to be due, with all costs, 
penalties, and interest thereon, promptly after such judgment becomes 
final; provided, however, in any event such contest shall be concluded 
and the tax, penalties, interest and costs shall be paid prior to the 
date any writ or order is issued under which any of Tenant's property 
that is material to the business of Tenant and its Subsidiaries taken as 
a whole may be seized or sold because of the nonpayment thereof.

     (n)  Operation of Property.  During the Term, Tenant shall operate 
the Leased Property in a good and workmanlike manner and substantially 
in compliance with all Applicable Laws and will pay or cause to be paid 
all fees or charges of any kind in connection therewith.  (If Tenant 
does not promptly correct any failure of the Leased Property to comply 
with Applicable Laws that is the subject of a written notice given to 
Tenant or Landlord by any governmental authority, then for purposes of 
the preceding sentence, Tenant shall be considered not to have 
maintained the Leased Property "substantially in accordance with 
Applicable Laws" whether or not the noncompliance would be substantial 
in the absence of the notice.)  During the Term, Tenant shall not use or 
occupy, or allow the use or occupancy of, the Leased Property in any 
manner which violates any Applicable Law or which constitutes a public 
or private nuisance or which makes void, voidable or cancelable any 
insurance then in force with respect thereto.  During the Term, to the 
extent that any of the following would, individually or in the 
aggregate, materially and adversely affect the value of the Leased 
Property or Tenant's use, occupancy or operations on the Leased 
Property, Tenant shall not, without Landlord's prior consent:  (i) 
initiate or permit any zoning reclassification of the Leased Property; 
(ii) seek any variance under existing zoning ordinances applicable to 
the Leased Property; (iii) use or permit the use of the Leased Property 
in a manner that would result in such use becoming a nonconforming use 
under applicable zoning ordinances or similar laws, rules or 
regulations; (iv) subject to Paragraph 10(b) below, execute or file any 
subdivision plat affecting the Leased Property; or (v) consent to the 
annexation of the Leased Property to any municipality.  During the Term, 
if (A) a change in the zoning or other Applicable Laws affecting the 
permitted use or development of the Leased Property shall occur that 
reduces Appraised Value, or (B) conditions or circumstances on or about 
the Leased Property are discovered (such as the presence of an 
endangered species) which substantially impede development and thereby 
reduce Appraised Value, and if after any such reduction under clause (A) 
or (B) above Appraised Value of the Leased Property is less than thirty 
percent (30%) of Stipulated Loss Value, then Tenant shall pay Landlord 
upon request the amount by which Appraised Value is less than thirty 
percent (30%) of Stipulated Loss Value, for application as a Qualified 
Payment.  For purposes of determining Appraised Value under the 
preceding sentence, the provisions of subparagraph 4(a)(v) shall apply.  
During the Term, Tenant shall not cause or permit any drilling or 
exploration for, or extraction, removal or production of, minerals from 
the surface or subsurface of the Leased Property, and Tenant shall not 
do any act whereby the market value of the Leased Property may 
reasonably be expected to be materially lessened.  Subject to Paragraph 
23, during the Term, Tenant shall allow Landlord or its authorized 
representative to enter the Leased Property at any reasonable time to 
inspect the Leased Property and, after reasonable notice, to inspect 
Tenant's books and records pertaining thereto, and Tenant shall assist 
Landlord or Landlord's representative in whatever way reasonably 
necessary to make such inspections.  During the Term, if Tenant receives 
a written notice or claim from any federal, state or other governmental 
entity that the Leased Property is not in compliance in any material 
respect with any Applicable Law, or that any action may be taken against 
the owner of the Leased Property because the Leased Property does not 
comply with Applicable Law, Tenant shall promptly furnish a copy of such 
notice or claim to Landlord.  Notwithstanding the foregoing, Tenant may 
in good faith by appropriate proceedings contest the validity and 
applicability of any Applicable Law with respect to the Leased Property, 
and pending such contest Tenant shall not be deemed in default hereunder 
because of a violation of such Applicable Law, if Tenant diligently 
prosecutes such contest to completion in a manner reasonably 
satisfactory to Landlord, and if Tenant promptly causes the Leased 
Property to comply with any such Applicable Law upon a final 
determination by a court of competent jurisdiction that the same is 
valid and applicable to the Leased Property; provided, that in any event 
such contest shall be concluded and the violation of such Applicable Law 
must be corrected (in a manner that will not materially impede future 
development of the Leased Property) and any claims asserted against 
Landlord or the Leased Property because of such violation must be paid 
by Tenant, all prior to (i) any Designated Payment Date on which neither 
Tenant nor any Applicable Purchaser purchases the Leased Property 
pursuant to the Purchase Agreement for a net price to Landlord (when 
taken together with any additional payments made by Tenant pursuant to 
Paragraph 2(a)(ii) of the Purchase Agreement, in the case of a purchase 
by an Applicable Purchaser) of not less than Stipulated Loss Value, (ii) 
the date any criminal charges may be brought against Landlord or any of 
its directors, officers or employees because of such violation or (iii) 
the date any action may be taken by any governmental authority against 
Landlord or any property owned by Landlord (including the Leased 
Property) because of such violation.

     (o)  Debts for Construction.  During the Term, Tenant shall cause 
all debts and liabilities incurred in the construction, maintenance, 
operation and development of the Leased Property, including without 
limitation all debts and liabilities for labor, material and equipment 
and all debts and charges for utilities servicing the Leased Property, 
to be promptly paid.  Notwithstanding the foregoing, Tenant may in good 
faith by appropriate proceedings contest the validity, applicability or 
amount of any asserted mechanic's or materialmen's lien and pending such 
contest Tenant shall not be deemed in default under this subparagraph 
(or subparagraph 9(t)) because of the contested lien if (1) within sixty 
(60) days after being asked to do so by Landlord, Tenant bonds over to 
Landlord's satisfaction any contested liens alleged to secure an amount 
in excess of $1,000,000 (individually or in the aggregate) (2) Tenant 
diligently prosecutes such contest to completion in a manner reasonably 
satisfactory to Landlord, and (3) Tenant promptly causes to be paid any 
amount adjudged by a court of competent jurisdiction to be due, with all 
costs and interest thereon, promptly after such judgment becomes final; 
provided, however, that in any event each such contest shall be 
concluded and the lien, interest and costs shall be paid prior to (i) 
any Designated Payment Date on which neither Tenant nor any Applicable 
Purchaser purchases the Leased Property pursuant to the Purchase 
Agreement for a net price to Landlord (when taken together with any 
additional payments made by Tenant pursuant to Paragraph 2(a)(ii) of the 
Purchase Agreement, in the case of a purchase by an Applicable 
Purchaser) of not less than Stipulated Loss Value, (ii) the date any 
criminal action may be instituted against Landlord or its directors, 
officers or employees because of the nonpayment thereof or (iii) any 
writ or order is issued under which any property owned by Landlord 
(including the Leased Property) may be seized or sold or any other 
action may be taken against Landlord or any property owned by Landlord 
because of the nonpayment thereof.

     (p)  Impositions.  Tenant shall reimburse Landlord for (or, if 
requested by Landlord, will pay or cause to be paid prior to 
delinquency) all sales, excise, ad valorem, gross receipts, business, 
transfer, stamp, occupancy, rental and other taxes, levies, fees, 
charges, surcharges, assessments or penalties which arise out of or are 
attributable to this Lease or which are imposed upon Landlord or the 
Leased Property because of the ownership, leasing, occupancy, sale, 
development or operation of the Leased Property, or any part thereof, 
during the Term or which relate to or are required to be paid during the 
Term by the terms of any of the Permitted Encumbrances (collectively, 
herein called the "Impositions"), excluding only (and in every case) 
Excluded Taxes.  If Landlord requires Tenant to pay any Impositions 
directly to the applicable taxing authority or other party entitled to 
collect the same, Tenant shall furnish Landlord with receipts showing 
payment of such Impositions and other amounts prior to delinquency; 
except that Tenant may in good faith by appropriate proceedings contest 
the validity, applicability or amount of any asserted Imposition, and 
pending such contest Tenant shall not be deemed in default of this 
subparagraph 9(p) (or subparagraph 9(t)) because of the contested 
Imposition if (1) within sixty (60) days after being asked to do so by 
Landlord, Tenant bonds over to the satisfaction of Landlord any lien 
asserted against the Leased Property and alleged to secure an amount in 
excess of $1,000,000 because of the contested Imposition (2) Tenant 
diligently prosecutes such contest to completion in a manner reasonably 
satisfactory to Landlord, and (3) Tenant promptly causes to be paid any 
amount adjudged by a court of competent jurisdiction to be due, with all 
costs, penalties and interest thereon, promptly after such judgment 
becomes final; provided, however, that in any event each such contest 
shall be concluded and the Impositions, penalties, interest and costs 
shall be paid prior to (i) any Designated Payment Date on which neither 
Tenant nor any Applicable Purchaser purchases the Leased Property 
pursuant to the Purchase Agreement for a net price to Landlord (when 
taken together with any additional payments made by Tenant pursuant to 
Paragraph 2(a)(ii) of the Purchase Agreement, in the case of a purchase 
by an Applicable Purchaser) of not less than Stipulated Loss Value, (ii) 
the date any criminal action may be instituted against Landlord or its 
directors, officers or employees because of the nonpayment thereof or 
(iii) the date any writ or order is issued under which any property 
owned by Landlord (including the Leased Property) may be seized or sold 
or any other action may be taken against Landlord or any property owned 
by Landlord because of the nonpayment thereof.  As used herein, 
"Impositions" shall include real estate taxes imposed because of a 
change of use or ownership of the Leased Property, including, to the 
extent attributable to the term of this Lease or any prior period, any 
such real estate taxes imposed because of a change in use or ownership 
after the term of this Lease expires or is terminated.

     (q)  Repair, Maintenance, Alterations and Additions.  During the 
Term, Tenant shall keep the Leased Property in good order, repair, 
operating condition and appearance (subject to reasonable deviations 
required to accommodate Construction Projects permitted by this Lease 
and ordinary wear and tear) and shall cause all necessary repairs, 
renewals, replacements, additions and improvements to the Leased 
Property to be promptly made.  Tenant shall not allow the Leased 
Property to be materially misused, abused or wasted or to deteriorate 
(subject to reasonable deviations required to accommodate Construction 
Projects permitted by this Lease and ordinary wear and tear), and Tenant 
shall promptly replace any worn-out fixtures and Personal Property with 
fixtures and Personal Property comparable to the replaced items when 
new.  Tenant shall not, without the prior written consent of Landlord, 
(i) remove from the Leased Property any fixture or Personal Property 
having significant value except such as are replaced by Tenant by 
fixtures or Personal Property of equal suitability and value, free and 
clear of any lien or security interest (and for purposes of this clause 
"significant value" will mean any fixture or Personal Property that has 
a value of more than $100,000 or that, when considered together with all 
other fixtures and Personal Property removed and not replaced by Tenant 
by items of equal suitability and value, has an aggregate value of 
$1,000,000 or more) or (ii) make or alter Improvements except as part of 
Construction Projects meeting the requirements of Paragraph 6(b).  At 
any time requested by Landlord, Tenant shall deliver to Landlord an 
inventory describing and showing the make, model, serial number and 
location of each item of Personal Property having a significant value 
with a certification by Tenant that such inventory is true and complete 
and that all items specified in the inventory are free and clear of any 
lien or security interest other than the Permitted Encumbrances 
described in Exhibit B.

     (r)  Insurance and Casualty.  Throughout the Term, Tenant shall 
keep all Improvements (other than Improvements consisting only of 
grading and other site work) and tangible Personal Property covered by 
insurance against damage or destruction by fire or other casualty in the 
amount of one hundred percent (100%) of the replacement value.  The 
policy or policies under which such insurance is maintained shall 
include endorsements for contingent liability from operation of building 
laws and increased cost of construction and demolition costs which may 
be necessary to comply with building laws.  Such insurance shall, except 
to the extent provided under a builder's risk policy maintained as 
required by subparagraph 6(c)(iii)b) above during the construction of 
any Construction Project, be provided under an all-risk property 
insurance policy (not excluding from coverage perils normally included 
within the definitions of extended coverage, vandalism and malicious 
mischief and flood, but not including earthquake coverage).  Tenant will 
be responsible for determining the amount of property insurance to be 
maintained, but such coverage will be on an agreed value basis to 
eliminate the effects of coinsurance.  Such insurance shall be issued by 
an insurance company or companies rated by the A.M. Best Company of 
Oldwick, New Jersey as having a policyholder's rating of A or better and 
a reported financial information rating of X or better. Any deductible 
applicable to such insurance shall not exceed $1,000,000.  Such 
insurance shall cover not only the value of Tenant's interest in the 
applicable Improvements and tangible Personal Property, but also the 
interest of Landlord, and such insurance shall include provisions that 
Landlord must be notified at least ten (10) days prior to any 
cancellation or reduction of insurance coverage.  With this Lease Tenant 
shall deliver to Landlord a certificate from the applicable insurer or 
its authorized agent evidencing the insurance required by this 
subparagraph and any additional insurance which shall be taken out upon 
any part of the Leased Property.  Thereafter during the Term, Tenant 
shall deliver to Landlord certificates from the applicable insurer or 
its authorized agent in form reasonably satisfactory to Landlord 
evidencing renewals or replacements of all such policies of insurance at 
least fifteen (15) days before any such insurance shall expire.  Tenant 
further agrees that all such policies shall provide that proceeds 
thereunder will be payable to Landlord as Landlord's interest may 
appear, without reduction because of any negligence or other acts or 
omissions of Tenant (including any use of the Leased Property by Tenant 
for a purpose more hazardous than that permitted by the terms of the 
applicable insurance policy).  If Tenant fails to obtain any insurance 
required by this Lease or to provide confirmation of any such insurance 
as required by this Lease, Landlord shall be entitled (but not required) 
to obtain the insurance that Tenant has failed to obtain or for which 
Tenant has not provided the required confirmation and, without limiting 
Landlord's other remedies under the circumstances, Landlord may require 
Tenant to reimburse Landlord for the cost of such insurance and to pay 
interest thereon computed at the Default Rate from the date such cost 
was paid by Landlord until the date of reimbursement by Tenant.  In the 
event any of the Leased Property is destroyed or damaged by fire, 
explosion, windstorm, hail or by any other casualty against which 
insurance shall have been required hereunder, (i) Landlord may, but 
shall not be obligated to, make proof of loss if not made promptly by 
Tenant, (ii) each insurance company concerned is hereby authorized and 
directed to make payment for such loss directly to Landlord for 
application as required by Paragraph 4, and (iii) Landlord may settle, 
adjust or compromise any and all claims for loss, damage or destruction 
under any policy or policies of insurance (provided, that if any such 
claim is for less than $10,000,000 and no Event of Default shall have 
occurred and be continuing, Tenant shall have the right to settle, 
adjust or compromise the claim as Tenant deems appropriate; and, 
provided further, that so long as no Event of Default shall have 
occurred and be continuing, Landlord must provide Tenant with at least 
forty-five (45) days notice of Landlord's intention to settle any such 
claim before settling it unless Tenant shall already have approved of 
the settlement by Landlord).  If any casualty shall result in damage to 
or loss or destruction of the Leased Property in excess of $1,000,000, 
Tenant shall give immediate notice thereof to Landlord and Paragraph 4 
shall apply.  In the event that insurance proceeds totaling not more 
than $1,000,000 are collected as a result of a fire or other casualty 
involving the Leased Property, Tenant may directly receive such proceeds 
so long as no Event of Default shall have occurred and be continuing and 
so long as Tenant applies such proceeds towards the restoration, 
replacement and repair of the Leased Property as provided under 
subparagraph 4(a)(iv).

     (s)  Condemnation.  During the Term, immediately upon obtaining 
knowledge of the institution of any proceedings for the condemnation of 
the Leased Property or any portion thereof, or any other similar 
governmental or quasi-governmental proceedings arising out of injury or 
damage to the Leased Property or any portion thereof, Tenant shall 
notify Landlord of the pendency of such proceedings.  Tenant shall, at 
its expense, diligently prosecute any such proceedings and shall consult 
with Landlord, its attorneys and experts and cooperate with them as 
reasonably requested in the carrying on or defense of any such 
proceedings.  All proceeds of condemnation awards or proceeds of sale in 
lieu of condemnation with respect to the Leased Property and all 
judgments, decrees and awards for injury or damage to the Leased 
Property shall be paid to Landlord and applied as provided in Paragraph 
4 above.  Landlord is hereby authorized, in the name of Tenant, to 
execute and deliver valid acquittances for, and to appeal from, any such 
judgment, decree or award concerning condemnation of any of the Leased 
Property.  Landlord shall not be, in any event or circumstances, liable 
or responsible for failure to collect, or to exercise diligence in the 
collection of, any such proceeds, judgments, decrees or awards.

     (t)  Protection and Defense of Title Against Liens and Other 
Encumbrances or Defects.  If any encumbrance or title defect whatsoever 
affecting the fee interest in the Leased Property is claimed or 
discovered (including Liens against any part of or interest in the 
Leased Property, whether or not expressly subordinate to this Lease or 
Landlord's interest in the Leased Property, but excluding Permitted 
Encumbrances, this Lease and any other encumbrance which is claimed by 
Landlord or lawfully claimed through or under Landlord and which is not 
claimed by, through or under Tenant) or if any legal proceedings are 
instituted with respect to title to the Leased Property, Tenant shall 
give prompt written notice thereof to Landlord and at Tenant's own cost 
and expense will promptly cause the removal of any such encumbrance and 
cure any such defect and will take all necessary and proper steps for 
the defense of any such legal proceedings, including but not limited to 
the employment of counsel, the prosecution or defense of litigation and 
the release or discharge of all adverse claims.  If Tenant fails to 
promptly remove any such encumbrance or title defect, Landlord (whether 
or not named as a party to legal proceedings with respect thereto) shall 
be entitled to take such additional steps as in its judgment may be 
necessary or proper to remove such encumbrance or cure such defect or 
for the defense of any such attack or legal proceedings or the 
protection of Landlord's fee interest in the Leased Property, including 
but not limited to the employment of counsel, the prosecution or defense 
of litigation, the compromise or discharge of any adverse claims made 
with respect to the Leased Property, the removal of prior liens or 
security interests, and all expenses (including Attorneys' Fees) so 
incurred of every kind and character shall be a demand obligation owing 
by Tenant.

     For purposes of this subparagraph 9(t), Tenant shall be deemed to 
be acting promptly to remove any encumbrance or to cure any title 
defect, other than a Lien which Tenant has itself granted or authorized, 
so long as Tenant is in good faith by appropriate proceedings contesting 
the validity and applicability of the encumbrance or defect, and pending 
such contest Tenant shall not be deemed in default under this 
subparagraph because of the encumbrance or defect; provided, with 
respect to a contest of any encumbrance or title defect which is the 
subject of subparagraphs 9(o) or 9(p), Tenant must satisfy the 
conditions and requirements for a permitted contest set forth in those 
subparagraphs, and with respect to a contest of any other encumbrance or 
title defect, Tenant must satisfy the following conditions and 
requirements:

          (1) Tenant must diligently prosecute the contest to completion 
in a manner reasonably satisfactory to Landlord.

          (2) Tenant must immediately remove the encumbrance or cure the 
defect upon a final determination by a court of competent jurisdiction 
that it is valid and applicable to the Leased Property.

          (3) Tenant must in any event conclude the contest and remove 
the encumbrance or cure the defect and pay any claims asserted against 
Landlord or the Leased Property because of such encumbrance or defect, 
all prior to (i) any Designated Payment Date on which neither Tenant nor 
any Applicable Purchaser purchases the Leased Property pursuant to the 
Purchase Agreement for a net price to Landlord (when taken together with 
any additional payments made by Tenant pursuant to Paragraph 2(a)(ii) of 
the Purchase Agreement, in the case of a purchase by an Applicable 
Purchaser) of not less than Stipulated Loss Value, (ii) the date any 
criminal charges may be brought against Landlord or any of its 
directors, officers or employees because of such encumbrance or defect 
or (iii) the date any action may be taken against Landlord or any 
property owned by Landlord (including the Leased Property) by any 
governmental authority or any other Person who has or claims rights 
superior to Landlord because of the encumbrance or defect.

     (u)  Books and Records.  During the Term Tenant shall keep books 
and records that are accurate and complete in all material respects for 
the  operations affecting the Leased Property and shall, subject to 
Paragraph 23, permit all such books and records (including without 
limitation records which evidence the testing and validation of the 
Leased Property required for the use thereof as described in 
subparagraph 8(a), as well as all contracts, statements, invoices, bills 
and claims for labor, materials and services supplied for the 
construction and operation of Improvements) to be inspected and copied 
by Landlord and its duly accredited representatives at all times during 
reasonable business hours after five (5) Business Days advance written 
notice and no more than twice in any twelve (12) month period (except 
when an Event of Default has occurred and is continuing).  This 
subparagraph shall not be construed as requiring Tenant to regularly 
maintain separate books and records relating exclusively to the Leased 
Property; provided, however, that upon request, Tenant shall construct 
or abstract from its regularly maintained books and records information 
required by this subparagraph relating to the Leased Property.

     (v)  Financial Statements; Required Notices; Certificates.  During 
the Term, Tenant shall deliver to Landlord and to each Participant:

          (i)  as soon as available and in any event within one hundred 
twenty (120) days after the end of each fiscal year of Tenant, a 
consolidated balance sheet of Tenant and its Consolidated Subsidiaries 
as of the end of such fiscal year and a consolidated income statement 
and statement of cash flows of Tenant and its Consolidated Subsidiaries 
for such fiscal year, all in reasonable detail and all prepared in 
accordance with GAAP and accompanied by a report and opinion of 
accountants of national standing selected by Tenant, which report and 
opinion shall be prepared in accordance with generally accepted auditing 
standards and shall not be subject to any qualifications or exceptions 
as to the scope of the audit nor to any qualification or exception which 
Landlord determines, in Landlord's reasonable discretion, is 
unacceptable;

         (ii)  as soon as available and in any event within sixty (60) 
days after the end of each of the first three quarters of each fiscal 
year of Tenant, the consolidated balance sheet of Tenant and its 
Consolidated Subsidiaries as of the end of such quarter and the 
consolidated income statement and the consolidated statement of cash 
flows of Tenant and its Consolidated Subsidiaries for the period 
commencing at the end of the previous fiscal year and ending with the 
end of such quarter, all in reasonable detail and all prepared in 
accordance with GAAP and certified by the chief financial officer or 
controller of Tenant (subject to year-end adjustments);

        (iii)  together with the financial statements furnished in 
accordance with subparagraph 9(v)(ii) and 9(v)(i), a certificate of the 
chief financial officer or controller of Tenant in substantially the 
form attached hereto as Exhibit F: (i) certifying that to the knowledge

is continuing, a brief statement as to the nature thereof and the action 
which is proposed to be taken with respect thereto, (ii) certifying that 
the representations of Tenant set forth in Paragraph 9 of this Lease are 
true and correct in all material respects as of the date thereof as 
though made on and as of the date thereof or, if not then true and 
correct, a brief statement as to why such representations are no longer 
true and correct, and (iii) with computations demonstrating compliance 
with the financial covenants contained in subparagraph 9(ab);

         (iv)  promptly after the sending or filing thereof, copies of 
all proxy statements, financial statements and reports which Tenant 
sends to Tenant's stockholders, and copies of all regular, periodic and 
special reports, and all registration statements (other than 
registration statements on Form S-8 or any form substituted therefor) 
which Tenant files with the Securities and Exchange Commission or any 
governmental authority which may be substituted therefor, or with any 
national securities exchange;

          (v)  upon request by Landlord, a statement in writing

there have been modifications, that this Lease is in full effect as 
modified, and setting forth such modifications) and the dates to which 
the Base Rent has been paid and either stating that to the knowledge of 
Tenant no Default or Event of Default under this Lease has occurred and 
is continuing or, if a Default or Event of Default under this Lease has 
occurred and is continuing, a brief statement as to the nature thereof; 
it being intended that any such statement by Tenant may be relied upon 
by any prospective purchaser or mortgagee of the Leased Property and by 
the Participants; and

         (vi)  subject to Paragraph 23, such other information 
respecting the condition or operations, financial or otherwise, of 
Tenant, of any of its Subsidiaries or of the Leased Property as Landlord 
or any Participant through Landlord may from time to time reasonably 
request.

Landlord is hereby authorized to deliver a copy of any information or 
certificate delivered to it pursuant to this subparagraph 9(v) to 
Landlord's Parent, to the Participants and to any regulatory body having 
jurisdiction over Landlord or Landlord's Parent or any Participant that 
requires or requests it, but in connection therewith Landlord will, if 
practicable, request confidential treatment of any information described 
in clauses (iii) and (vi).

     (w)  Further Assurances.  During the Term Tenant shall, on request 
of Landlord, (i) promptly correct any defect or error which may be 
discovered in the contents of this Lease or in any other instrument 
executed in connection herewith or in the execution or acknowledgment 
thereof as may be necessary, desirable or proper to carry out more 
effectively the purposes of this Lease or such other document; (ii) 
execute, acknowledge, deliver and record or file such further 
instruments and do such further acts as may be necessary, desirable or 
proper to carry out more effectively the purposes of this Lease and to 
subject to this Lease any property intended by the terms hereof to be 
covered hereby including specifically, but without limitation, any 
renewals, additions, substitutions, replacements or appurtenances to the 
Leased Property; (iii) execute, acknowledge, deliver, procure and record 
or file any document or instrument deemed advisable by Landlord to 
protect its rights in and to the Leased Property against the rights or 
interests of third persons; and (iv) provide such certificates, 
documents, reports, information, affidavits and other instruments and do 
such further acts as may be necessary, desirable or proper in the 
reasonable determination of Landlord to enable Landlord, Landlord's 
Parent and Participants to comply with the requirements or requests of 
any agency or authority having jurisdiction over them.

     (x)  Fees and Expenses; Indemnification; Increased Costs; and 
Capital Adequacy Charges.

          (i)  Except for any costs and expenses paid by Landlord with 
the proceeds of the Initial Funding Advances as part of the Transaction 
Expenses, Tenant shall pay (and shall indemnify and hold harmless 
Landlord, Landlord's Parent and any Person claiming through Landlord by 
reason of a Permitted Transfer from and against) all Losses incurred by 
Landlord or Landlord's Parent or any Person claiming through Landlord 
through a Permitted Transfer in connection with or because of (A) the 
ownership of any interest in or operation of the Leased Property, (B) 
the negotiation or administration of this Lease or the Purchase 
Agreement or the participation agreements concerning this Lease between 
Landlord and Participants (excluding, however, any costs or expenses 
incurred by Participants for the review, negotiation or administration 
(absent an Event of Default) of this Lease, the Purchase Agreement or 
such participation agreements and any costs or expenses incurred by 
Landlord or any transferee to accomplish any Permitted Transfers 
described in clauses (2), (3) or (5) of subparagraph 1(bu)), or (C) 
Construction Projects, whether such Losses are incurred at the time of 
execution of this Lease or at any time during the Term.  Costs and 
expenses included in such Losses may include, without limitation, all 
appraisal fees, filing and recording fees, inspection fees, survey fees, 
taxes (other than Excluded Taxes), brokerage fees and commissions, 
abstract fees, title policy fees, Uniform Commercial Code search fees, 
escrow fees, Attorneys' Fees and reasonable environmental consulting 
fees incurred by Landlord with respect to the Leased Property.  If 
Landlord pays or reimburses Landlord's Parent for any such Losses, 
Tenant shall reimburse Landlord for the same notwithstanding that 
Landlord may have already received any payment from any Participant on 
account of such Losses, it being understood that the Participant may 
expect repayment from Landlord when Landlord does collect the required 
reimbursement from Tenant.  Tenant shall be entitled to pay any of the 
foregoing Losses for which Tenant is responsible hereunder out of 
Construction Advances, subject to all of the conditions to Construction 
Advances set forth in Paragraph 6 hereof.

         (ii)  Tenant shall also pay (and indemnify and hold harmless 
Landlord, Landlord's Parent and any Person claiming through Landlord by 
reason of a Permitted Transfer from and against) all Losses, including 
Attorneys' Fees, incurred or expended by Landlord or Landlord's Parent 
or any Person claiming through Landlord through a Permitted Transfer in 
connection with (A) the breach by Tenant of any covenant of Tenant 
herein or in any other instrument executed in connection herewith or (B) 
Landlord's exercise of any of Landlord's rights and remedies hereunder 
or under Applicable Law or Landlord's protection of the Leased Property 
and Landlord's interest therein as permitted hereunder or under 
Applicable Law.  (However, the indemnity in the preceding sentence shall 
not be construed to make Tenant liable to both Landlord and any 
Participant or other party claiming through Landlord for the same 
damages.  For example, so long as Landlord remains entitled to recover 
any past due Base Rent from Tenant, no Participant shall be entitled to 
collect a percentage of the same Base Rent from Tenant.)  Tenant shall 
further indemnify and hold harmless Landlord and all other Indemnified 
Parties against, and reimburse them for, all Losses which may be imposed 
upon, asserted against or incurred or paid by them by reason of, on 
account of or in connection with any bodily injury or death or damage to 
the property of third parties occurring in or upon or in the vicinity of 
the Leased Property through any cause whatsoever.  The foregoing 
indemnity for injury, death or property damage shall apply even when 
injury, death or property damage in, on or in the vicinity of the Leased 
Property results in whole or in part from the negligence of an 
Indemnified Party; provided, such indemnity shall not apply to Losses 
suffered by an Indemnified Party that were proximately caused by (and 
attributed by any applicable principles of comparative fault to) the 
Active Negligence, gross negligence or wilful misconduct of such 
Indemnified Party or its Affiliates, agents or employees.

        (iii)  If, after the date hereof, due to either (A) the 
introduction of or any change (other than any change by way of 
imposition or increase of reserve requirements included in the 
Eurodollar Rate Reserve Percentage) in or in the interpretation of any 
law or regulation or (B) the compliance with any guideline or request 
from any central bank or other governmental authority (whether or not 
having the force of law), there shall be any increase in the cost to 
Landlord's Parent or any Participant of agreeing to make or making, 
funding or maintaining advances to Landlord in connection with the 
Leased Property, then Tenant shall from time to time, upon demand by 
Landlord pay to Landlord for the account of Landlord's Parent or such 
Participant, as the case may be, additional amounts sufficient to 
compensate Landlord's Parent or the Participant for such increased cost.  
However, the aggregate of such additional amounts payable for the 
account of any original Participant listed in Schedule 1 and all Persons 
who may qualify as Participants through permitted assignments from such 
original Participant shall not exceed the additional amounts that would 
have been payable to such original Participant absent any assignments by 
it of its rights under its participation agreement with Landlord.  A 
certificate as to the amount of such increased cost, submitted to 
Landlord and Tenant by Landlord's Parent or the Participant, shall be 
conclusive and binding for all purposes, absent clear and demonstrable 
error.

         (iv)  If Landlord's Parent or any Participant determines that 
any law or regulation or any guideline or request from any central bank 
or other governmental authority (whether or not having the force of law) 
affects the amount of capital to be maintained by it and that the amount 
of such capital is increased by or based upon the existence of advances 
made or to be made to Landlord to permit Landlord to maintain Landlord's 
investment in the Leased Property, then to the extent that Landlord's 
Parent or the Participant reasonably determines that the increase in 
required capital is allocable to such advances, Tenant shall pay 
Landlord additional amounts (herein called "Capital Adequacy Charges") 
for the account of Landlord's Parent or the Participant, as the case may 
be, as Landlord's Parent or the Participant may specify as sufficient to 
compensate it in light of such circumstances. 

          (v)  Any amount to be paid to Landlord, Landlord's Parent or 
any Indemnified Party under this subparagraph 9(x) shall be a demand 
obligation owing by Tenant.  Tenant's indemnities and obligations under 
this subparagraph 9(x) shall survive the termination or expiration of 
this Lease with respect to any circumstance or event existing or 
occurring prior to such termination or expiration.

     (y)  Liability Insurance.  During the Term, Tenant shall maintain 
commercial general liability insurance against claims for bodily injury 
or death and property damage occurring or resulting from any occurrence 
in or upon the Leased Property, in standard form and with an insurance 
company or companies rated by the A.M. Best Company of Oldwick, New 
Jersey as having a policyholder's rating of A or better and a reported 
financial information rating of X or better, such insurance to afford 
immediate protection, to the limit of not less than $10,000,000 combined 
single limit for bodily injury and property damage in respect of any one 
accident or occurrence, with not more than $1,000,000 self-insured 
retention.  Such commercial general liability insurance shall include 
blanket contractual liability coverage which insures contractual 
liability under the indemnifications set forth in this Lease (other than 
the indemnifications set forth in Paragraph 12 concerning environmental 
matters), but such coverage or the amount thereof shall in no way limit 
such indemnifications.  The policy evidencing such insurance shall name 
as additional insureds Landlord, Landlord's Parent and the Participants.  
Tenant shall maintain with respect to each policy or agreement 
evidencing such commercial general liability insurance such endorsements 
as may be reasonably required by Landlord and shall at all times deliver 
and maintain with Landlord written certificates with respect to such 
insurance from the applicable insurer or its authorized agent in form 
satisfactory to Landlord, which certificates must provide that insurance 
coverage will not be canceled or reduced without at least thirty (30) 
days notice to Landlord.  Not less than fifteen (15) days prior to the 
expiration date of each policy of insurance required of Tenant pursuant 
to this subparagraph, Tenant shall deliver to Landlord a certificate 
evidencing a paid renewal policy or policies.

     (z)  Permitted Encumbrances.  Except to the extent expressly 
required of Landlord by subparagraph 10(b), Tenant shall during the Term 
comply with and will cause to be performed all of the covenants, 
agreements and obligations imposed upon the owner of the Leased Property 
in the Permitted Encumbrances in accordance with their respective terms 
and provisions.  Tenant shall not modify or permit any modification of 
any Permitted Encumbrance in any manner that could be binding upon 
Landlord or any future owner of the Leased Property (other than Tenant 
or an Applicable Purchaser or the successors or assigns of Tenant or an 
Applicable Purchaser) without first requesting and obtaining the prior 
written consent of Landlord.  Whether Landlord must give or may withhold 
any such consent will be governed by subparagraph 10(b).

     (aa)  Environmental Covenants.  During the Term, Tenant shall not 
cause or permit the Leased Property to be in violation of, or do 
anything or permit anything to be done which will subject the Leased 
Property to any remedial obligations under, any Environmental Laws, 
including without limitation CERCLA and RCRA, assuming disclosure to the 
applicable governmental authorities of all relevant facts, conditions 
and circumstances pertaining to the Leased Property, and Tenant shall 
promptly notify Landlord in writing of any existing, pending or, to the 
knowledge of Tenant, threatened investigation or inquiry by any 
governmental authority in connection with any suspected violation of the 
Leased Property under any Environmental Laws.  During the Term, Tenant 
shall not conduct or permit Hazardous Substance Activities, except 
Permitted Hazardous Substance Use.  During the Term, Tenant shall keep 
the Leased Property free of all Hazardous Substances (other than 
Permitted Hazardous Substances) and will remove the same (or if removal 
is prohibited by law, will take whatever action is required by law) 
promptly upon Tenant's discovery at Tenant's sole expense.  During the 
Term, in the event Tenant fails to comply with or perform any of the 
foregoing obligations concerning Hazardous Substance Activities and 
Hazardous Substances, Landlord may, in addition to any other remedies 
available to it, after notifying Tenant in writing in advance of the 
remediation efforts Landlord believes are needed, cause the Leased 
Property to be freed from all Hazardous Substances as provided above (or 
if removal is prohibited by law, may take whatever action is required by 
law) and take such other action as is necessary to cause the foregoing 
obligations to be met, and the cost of the removal and any such other 
action shall be a demand obligation owing by Tenant to Landlord.  For 
such removal and other action, Tenant grants to Landlord and Landlord's 
agents and employees access to the Leased Property and the license to 
remove Hazardous Substances as provided above (or if removal is 
prohibited by law or otherwise deemed inadvisable by Landlord, to take 
whatever action is required by law or otherwise deemed advisable by 
Landlord) and take such other action as is necessary to cause the 
foregoing obligations to be met, subject to Paragraph 23.  Further, 
subject to the provisions of subparagraph 12(c) below, Tenant agrees to 
indemnify Landlord against all Losses incurred by or asserted or proven 
against Landlord in connection therewith in accordance with Paragraph 
12.  During the Term, Tenant agrees to submit from time to time, if 
requested by Landlord, a certificate of an officer of Tenant, certifying 
that, except for Permitted Hazardous Substance Use, the Leased Property 
is not being used for, nor to Tenant's knowledge (except as may be 
described in the Environmental Report) has the Leased Property been used 
in the past for, any Hazardous Substances Activities.  Landlord reserves 
the right to retain an independent professional consultant to review any 
report prepared by Tenant or to conduct Landlord's own investigation to 
confirm whether Hazardous Substances Activities or the discharge of 
anything into groundwater or surface water has occurred, but Landlord's 
right to reimbursement for the fees of such consultant shall be limited 
to the following circumstances: (1) an Event of Default shall have 
occurred and be continuing; (2) Landlord shall have retained the 
consultant to establish the condition of the Leased Property just prior 
to any conveyance thereof pursuant to the Purchase Agreement or just 
prior to the expiration of this Lease; (3) Landlord shall have retained 
the consultant to satisfy any regulatory requirements applicable to 
Landlord or its Affiliates; or (4) Landlord shall have retained the 
consultant because Landlord has been notified of a violation of 
Environmental Laws concerning the Leased Property or Landlord otherwise 
reasonably believes that Tenant has not complied with this subparagraph.  
Subject to Paragraph 23, Tenant grants to Landlord and to Landlord's 
agents, employees, consultants and contractors the right during 
reasonable business hours and after reasonable advance written notice to 
enter upon the Leased Property to inspect the Leased Property and to 
perform such tests as are reasonably necessary or appropriate to conduct 
a review or investigation of Hazardous Substances on, or discharged into 
groundwater or surface water from, the Leased Property.  Tenant further 
agrees that Landlord will have the same right, power and authority to 
enter and inspect the Leased Property as is granted to a secured lender 
under Section 2929.5 of the California Civil Code.  Tenant shall 
promptly reimburse Landlord for the cost of any such inspections and 
tests, but only when the inspections and tests are: (1) ordered by 
Landlord after an Event of Default has occurred and is continuing; (2) 
ordered by Landlord to establish the condition of the Leased Property 
just prior to any conveyance thereof pursuant to the Purchase Agreement 
or just prior to the expiration of this Lease; (3) ordered by Landlord 
to satisfy any regulatory requirements applicable to Landlord or its 
Affiliates; or (4) ordered because Landlord has been notified of a 
violation of Environmental Laws concerning the Leased Property or 
Landlord otherwise reasonably believes that Tenant has not complied with 
this subparagraph.  During the Term, Tenant shall immediately advise 
Landlord of (i) Tenant's discovery of any event or circumstance which 
would render any of the representations contained in subparagraph 9(e) 
inaccurate in any material respect if made at the time of such 
discovery, (ii) any remedial action taken by Tenant in response to any 
(A) Hazardous Substances other than Permitted Hazardous Substances on, 
under or about the Leased Property or (B) any claim for damages 
resulting from Hazardous Substance Activities (herein called "Hazardous 
Substance Claims"), and (iii) Tenant's discovery of any occurrence or 
condition on any real property adjoining or in the vicinity of the 
Leased Property which creates a material risk of causing the Leased 
Property or any part thereof to be subject to significant ownership, 
occupancy, transferability or use restrictions under Environmental Laws 
or that could give rise to Hazardous Substance Claims.  In such event, 
Tenant shall deliver to Landlord within thirty (30) days after 
Landlord's request, a preliminary written environmental plan setting 
forth a general description of the action that Tenant proposes to take 
with respect thereto to bring the Leased Property into compliance with 
Environmental Laws (herein called a "Clean Up"), including, without 
limitation, any proposed corrective work, the estimated cost and time of 
completion, the name of the contractor and a copy of the construction 
contract, if any, and such additional data, instruments, documents, 
agreements or other materials or information as Landlord may reasonably 
request.  Tenant shall thereafter diligently and continuously pursue the 
Clean Up of the Leased Property in strict compliance with all 
Environmental Laws and shall inform Landlord monthly as to the status of 
the Clean Up.

     (ab)  Affirmative Financial Covenants.  During the Term:

          (i)  Minimum Tangible Net Worth.  On the last day of each 
fiscal quarter of Tenant, Consolidated Tangible Net Worth shall not be 
less than the sum of $1,000,000,000.00.

         (ii)  Leverage Ratio.  On the last day of each fiscal quarter 
of Tenant the ratio of Consolidated Total Liabilities to Consolidated 
Tangible Net Worth shall not be greater than 1.0 to 1.0.

        (iii)  Quick Ratio.  On the last day of each fiscal quarter of 
Tenant, the ratio of Consolidated Quick Assets to Consolidated Current 
Liabilities shall not be less than 3.75 to 1.0.

     (ac)  Negative Covenants.  During the Term, Tenant shall not, 
without the prior written consent of Landlord in each case: 

          (i)  Liens.  Create, incur, assume or suffer to exist, or 
permit any of its Consolidated Subsidiaries to create, incur, assume or 
suffer to exist, any Lien, upon or with respect to any of its 
properties, now owned or hereafter acquired, provided that the following 
shall be permitted except to the extent that they would encumber any 
interest in the Leased Property in violation of other provisions of this 
Lease:

               (1)  Liens for taxes or assessments or other government 
charges or levies if not yet due and payable or if they are being 
contested in good faith by appropriate proceedings (including contests 
expressly permitted by other provisions of this Lease) and for which 
appropriate reserves are maintained;

               (2)  Liens imposed by law, such as mechanic's, 
materialmen's, landlord's, warehousemen's and carrier's Liens, and other 
similar Liens, securing obligations incurred in the ordinary course of 
business which are not past due for more than thirty (30) days, or which 
are being contested in good faith by appropriate proceedings (including 
contests expressly permitted under other provisions of this Lease) and 
for which appropriate reserves have been established;

               (3)  Liens under workmen's compensation, unemployment 
insurance, social security or similar laws (other than ERISA);

               (4)  Liens, deposits or pledges to secure the performance 
of bids, tenders, contracts (other than contracts for the payment of 
money), leases, public or statutory obligations, surety, stay, appeal, 
indemnity, performance or other similar bonds, or other similar 
obligations arising in the ordinary course of business;

               (5)  judgment and other similar Liens against assets 
other than the Leased Property or any part thereof in an aggregate 
amount not in excess of $10,000,000 arising in connection with court 
proceedings; provided that the execution or other enforcement of such 
Liens is effectively stayed and the claims secured thereby are being 
actively contested in good faith by appropriate proceedings (including 
contests permitted under other provisions of this Lease) ;

               (6)  easements, rights-of-way, restrictions and other 
similar encumbrances which, in the aggregate, do not materially 
interfere with the occupation, use and enjoyment by Tenant or any such 
Consolidated Subsidiary of the property or assets encumbered thereby in 
the normal course of its business or materially impair the value of the 
property subject thereto;

               (7)  Liens securing obligations of such a Consolidated 
Subsidiary to Tenant or to another such Consolidated Subsidiary;

               (8)  Liens not otherwise permitted by this subsection 
9(ac)(i) (and not encumbering the Leased Property) incurred in 
connection with the incurrence of additional Debt or asserted to secure 
Unfunded Benefit Liabilities, provided that the sum of the aggregate 
principal amount of all outstanding Debt and any Unfunded Benefit 
Liabilities secured by Liens incurred pursuant to this clause (8) shall 
not at any time exceed thirty percent (30%) of Consolidated Tangible Net 
Worth at such time; and

               (9)  Liens incurred in connection with any renewals, 
extensions or refundings of any Debt secured by Liens described in the 
preceding clauses of this subsection 9(ac)(i), provided that there is no 
increase in the aggregate principal amount of Debt secured thereby from 
that which was outstanding as of the date of such renewal, extension or 
refunding and no additional property is encumbered.

     For purposes of this subparagraph 9(ac)(i), the following shall be 
deemed not to constitute Liens: this Lease, the Purchase Agreement and 
other documents being executed or accepted by Landlord in connection 
with this Lease; and other lease agreements, purchase agreements and 
similar documents executed or accepted by Landlord to evidence 
agreements between Landlord and Tenant concerning properties owned by 
Landlord and leased to Tenant, including but not limited to the existing 
Lease Agreements and Purchase Agreements between Landlord and Tenant 
dated November 19, 1993 and May 2, 1994, which concern properties leased 
by Landlord to Tenant in Tenant's South San Francisco campus known as 
Building 7 and Buildings 1 and 4, as the same may be renewed, increased, 
reduced, amended and/or restated from time to time.

         (ii)  Transactions with Affiliates.  Enter into or permit any 
Consolidated Subsidiary of Tenant to enter into any material 
transactions (including, without limitation, the purchase, sale or 
exchange of property or the rendering of any service) with any 
Affiliates of Tenant which would cause or result in a Default by Tenant 
under the financial covenants set forth in subparagraph 9(ab).

     (ad)  ERISA.  

          (i)  Each Plan, and, to the knowledge of Tenant, any 
Multiemployer Plan, is in compliance with, and has been administered in 
compliance with, the applicable provisions of ERISA, the Code and any 
other applicable Federal or state law in all respects, the failure to 
comply with which would have a material adverse effect upon the 
properties, assets, operations or businesses of Tenant and its 
Subsidiaries taken as a whole, and as of the date hereof no event or 
condition is occurring or exists which would require a notice from 
Tenant under clause 9(ad)(ii).

         (ii)  Tenant shall provide a notice to Landlord as soon as 
possible after, and in any event within ten (10) days after Tenant 
becomes aware that, any of the following has occurred, with respect to 
which the potential aggregate liability to Tenant relating thereto is 
$10,000,000 or more, and such notice shall include a statement signed by 
a senior financial officer of Tenant setting forth details of the 
following and the response, if any, which Tenant or its ERISA Affiliate 
proposes to take with respect thereto (and a copy of any report or 
notice required to be filed with or given to PBGC by Tenant or an ERISA 
Affiliate with respect to any of the following or the events or 
conditions leading up to the following):  (A) the assertion, to secure 
any Unfunded Benefit Liabilities, of any Lien against the assets of 
Tenant, against the assets of any Plan of Tenant or any ERISA Affiliate 
of Tenant or against any interest of Landlord or Tenant in the Leased 
Property, or (B) the taking of any action by the PBGC or any other 
governmental authority against Tenant to terminate any Plan of Tenant or 
any ERISA Affiliate of Tenant or to cause the appointment of a trustee 
or receiver to administer any such Plan.

     (ae)  Assignment of Certain Rights; Ownership of the Personal 
Property Purchased With Funds Provided by Landlord.  Subject in each 
case to the assignment and lease back as set forth on page 2 of this 
Lease and to subparagraph 10(c), and without limiting the obligations of 
Landlord under subparagraph 10(b):

          (i) Tenant hereby assigns to Landlord all of Tenant's right, 
title and interest, whether now existing or hereafter arising during the 
Term of this Lease, in and to (1) the Real Property itself, including 
any legal or equitable interest therein, but not including any interest 
created or arising under this Lease, the Purchase Agreement or the 
Environmental Indemnity Agreement; (2) the Contract (including without 
limitation, (A) the right upon valid tender to Seller to purchase the 
Real Property pursuant to the Contract at the purchase price set forth 
therein and the right to take title to the Real Property and be named 
the purchaser in the deed to be delivered by Seller; (B) all claims for 
damages in respect of the Contract, including, without limitation, all 
warranty and indemnity provisions in the Contract; (C) any and all 
rights of Tenant to compel performance of the terms of the Contract; and 
(D) without limiting the foregoing, any and all rights and benefits, 
including pursuant to representations, warranties, indemnities and 
covenants, arising under the Contract); and (3) each of the other 
Development Contracts, to the extent rights or interests under such 
Development Contracts can be assigned by Tenant to Landlord and then 
assigned and leased back hereunder as part of the Personal Property.  To 
the extent, if any, rights and interests of Tenant under any Development 
Contract cannot be assigned by Tenant to Landlord and then assigned and 
leased back as part of the Personal Property, Tenant will retain such 
rights and interests and agrees to enforce and maintain such rights and 
interests as Tenant would if it were the owner of the Leased Property.  
Thus, without limiting the foregoing, Landlord acknowledges and agrees 
that Tenant has not and cannot assign the "Financial Commitments" under 
and as defined in the Development Agreement described in Schedule 2.

         (ii)  All goods, equipment, furnishings, furniture, chattels, 
general intangibles, permits (to the extent assignable), licenses (to 
the extent assignable), franchises, certificates and other personal 
property of whatever nature and all renewals or replacements of or 
substitutions for any of the foregoing shall have been purchased for 
Landlord, be owned by Landlord and constitute Personal Property covered 
by this Lease, to the extent heretofore or hereafter purchased by 
Tenant, in whole or in part, with any portion of the Initial Funding 
Advances provided to Tenant or with any Construction Advances or with 
other funds for which Tenant has received or hereafter receives 
reimbursement from the Initial Funding Advances or Construction 
Advances.

  10  Other Representations and Covenants of Landlord.  Landlord 
represents and covenants as follows:

     (a)  Title Claims By, Through or Under Landlord.  Except by a 
Permitted Transfer, Landlord shall not assign, transfer, mortgage, 
pledge, encumber or hypothecate this Lease or any interest of Landlord 
in and to the Leased Property during the Term without the prior written 
consent of Tenant.  Landlord further agrees that if any encumbrance or 
title defect affecting the Leased Property is lawfully claimed through 
or under Landlord, including any judgment lien lawfully filed against 
Landlord, Landlord will at its own cost and expense promptly remove any 
such encumbrance and cure any such defect; provided, however, Landlord 
shall not be responsible for (i) any Permitted Encumbrances (regardless 
of whether claimed through or under Landlord) or any other encumbrances 
not lawfully claimed through or under Landlord, (ii) any encumbrances or 
title defects claimed by, through or under Tenant, or (iii) any 
encumbrance or title defect arising because of Landlord's compliance 
with subparagraph 10(b) or any request made by Tenant.

     (b)  Actions Required of the Title Holder.  So long as no Event of 
Default shall have occurred and be continuing, Landlord shall take any 
and all action required of Landlord by the Permitted Encumbrances or 
otherwise required of Landlord by Applicable Laws or reasonably 
requested by Tenant; provided, that (i) actions which Tenant may require 
of Landlord under this subparagraph shall be limited to actions that can 
only be taken by  Landlord as the owner of the Leased Property, as 
opposed to any action that can be taken by Tenant or any third party 
(and the payment of any monetary obligation shall not be an action 
required of Landlord under this subparagraph unless Landlord shall first 
have received funds from Tenant, in excess of any other amounts due from 
Tenant hereunder, sufficient to pay such monetary obligations), (ii) 
Tenant requests the action to be taken by Landlord (which request must 
be specific and in writing, if required by Landlord at the time the 
request is made) and (iii) the action to be taken will not constitute a 
violation of any Applicable Laws or compromise or constitute a waiver of 
Landlord's rights hereunder or under the Environmental Indemnity 
Agreement or the Purchase Agreement or otherwise be reasonably 
objectionable to Landlord.

     The actions Landlord shall perform if reasonably requested by 
Tenant will include, without limitation, but subject to the conditions 
set forth in the proviso of the preceding sentence, executing or 
consenting to, or exercising or assisting Tenant to exercise rights 
under any (I) grant of easements, licenses, rights of way, and other 
rights in the nature of easements encumbering the Real Property, (II) 
release or termination of easements, licenses, rights of way or other 
rights in the nature of easements which are for the benefit of the Real 
Property or any portion thereof, (III) dedication or transfer of 
portions of the Real Property not improved with a building, for road, 
highway or other public purposes, (IV) agreements for the use and 
maintenance of common areas, for reciprocal rights of parking, ingress 
and egress and amendments to any covenants and restrictions affecting 
the Real Property or any portion thereof, (V) documents required to 
create or administer a governmental special benefit district or 
assessment district for public improvements and collection of special 
assessments, (VI) instruments necessary or desirable for the exercise or 
enforcement of rights or performance of obligations of the buyer under 
the Contract or the exercise of rights or performance of obligations 
under any Permitted Encumbrance or any contract, permit, license, 
franchise or other right included within the term "Leased Property" 
(including, without limitation, under the Development Contracts), (VII) 
modifications of Permitted Encumbrances (including any Development 
Contracts), (VIII) permit applications or other documents required to 
accommodate Construction Projects permitted by this Lease, (IX) 
confirmations of Tenant's rights under any particular provisions of this 
Lease which Tenant may wish to provide to a third party or (X) execution 
or filing of a tract or parcel map subdividing the Real Property into 
lots or parcels.  However, the determination of whether any such action 
is reasonably requested or reasonably objectionable to Landlord may 
depend in whole or in part upon the extent to which the requested action 
shall result in a lien to secure payment or performance obligations 
against Landlord's interest in the Leased Property, shall cause a 
decrease in the value of the Leased Property to less than thirty percent 
(30%) of Stipulated Loss Value after any Qualified Payments that may 
result from such action are taken into account, or shall impose upon 
Landlord any present or future obligations greater than the obligations 
Landlord is willing to accept in reliance on the indemnifications 
provided by Tenant hereunder.


     So long as no Event of Default shall have occurred and be 
continuing, Tenant shall have the option from time to time during the 
Term to purchase or to designate one or more assignees to purchase one 
or more undeveloped portions of the Real Property consisting of one or 
more tracts or lots of the Land which can be sold under Applicable Laws 
separate and apart from the rest of the Land (each, a "Parcel"), for an 
amount equal to the Appraised Value thereof (such amount with respect to 
each Parcel being referred to herein as the "Parcel Release Price").  
Tenant may exercise such option by delivering to Landlord not less than 
ninety (90) days prior written notice, which written notice shall 
describe the Parcel or Parcels to be purchased, the date such Parcels 
are to be conveyed by Landlord and whether the conveyance will be to 
Tenant or an assignee designated in such notice.  In each case 
Landlord's obligation to convey such Parcels to Tenant or Tenant's 
assignee shall be subject to Tenant's and/or such assignee's 
satisfaction of each of the following conditions:

                a)  Landlord, Tenant and, if applicable, such assignee 
shall have agreed upon, entered into and recorded such reciprocal 
easements relating to the Land and the Parcel to be so sold as they 
shall deem necessary or reasonably required to preserve usefulness of 
the Parcels and the remaining Land after the conveyance;

                b)  It shall have been established that, following such 
conveyance and the application of the Partial Release Price as a 
Qualified Payment, Appraised Value of the Leased Property retained by 
Landlord will be no less than thirty percent (30%) of Stipulated Loss 
Value.  

                c)  Tenant or such assignee shall have paid to Landlord 
the Parcel Release Price for such Parcels; and

                d)  In addition to the Partial Release Price, Tenant or 
such assignee shall have paid all costs and expenses necessary to 
consummate the sale, including all legal fees of Landlord.

Upon Tenant's or such assignee's satisfaction of each of the foregoing 
conditions, Landlord shall convey such Parcel or Parcels to Tenant or 
such assignee pursuant to a quitclaim transfer of all of Landlord's 
right, title and interest therein on as "as is, where is, with all 
faults" basis free and clear of this Lease, the Purchase Agreement and 
all encumbrances claimed by Landlord or lawfully claimed through or 
under Landlord and which are not claimed by, through or under Tenant, 
but otherwise without recourse, representation or warranty of any kind.  


     In any event, all claims, demands, liabilities, losses, damages, 
judgments, penalties, costs and expenses incurred by Landlord because of 
any action taken pursuant to this subparagraph shall be covered by the 
indemnifications set forth in subparagraph 9(x).  Further, for purposes 
of such indemnification, any action taken by Landlord will be deemed to 
have been made at the request of Tenant if made pursuant to any request 
of Tenant's counsel or of any officer of Tenant (or with their 
knowledge, and without their objection) in connection with the execution 
of, closing under or enforcement of the Contract.

     (c)  Actions Permitted by Tenant Without Landlord's Consent.  No 
refusal by Landlord to execute or join in the execution of any 
agreement, application or other document requested by Tenant pursuant to 
the preceding subparagraph 10(b) shall preclude Tenant from itself 
executing such agreement, application or other document; provided, that 
in doing so Tenant is not purporting to act for Landlord and does not 
thereby create any encumbrance or cloud on Landlord's title to the 
Leased Property (other than any Permitted Encumbrance to which Landlord 
shall have already given its written approval or consent).  Further, 
subject to the other terms and conditions of this Lease (including 
subparagraph 9(z), which sets forth certain performance obligations of 
Tenant with respect to the Permitted Encumbrances), Tenant shall be 
entitled, because of the assignment and lease of Personal Property set 
forth on page 2 of this Lease, to do any of the following in Tenant's 
own name and to the exclusion of Landlord during the Term without any 
notice to or consent of Landlord so long as no Event of Default has 
occurred and is outstanding and so long as Tenant is not purporting to 
act for Landlord and does not thereby create any encumbrance or cloud on 
Landlord's title to the Leased Property (other than any Permitted 
Encumbrance to which Landlord shall have already given its written 
approval or consent):

         (A)  to perform obligations arising under and to exercise and 
enforce the rights of the buyer under the Contract;

         (B)  to perform obligations arising under and to exercise and 
enforce the rights of Tenant or the owner of the Real Property under the 
Development Contracts and other Permitted Encumbrances (including, 
without limitation, the exercise of all consent rights and voting rights 
of said owner as a member of the Vaca Valley Business Park Association 
under the Declaration of Covenants, Conditions and Restrictions for the 
Vaca Valley Business Park described in Schedule 2 and any applicable by-
laws, articles of incorporation or similar documents of such 
Association);

         (C)  to perform obligations arising under and to exercise and 
enforce the rights of Tenant or the owner of the Real Property with 
respect to the creation and operation of and obtaining of financing by 
the Assessment District (as defined in the Contract); 

         (D)  to perform obligations arising under and to exercise and 
enforce the rights of Tenant or the owner of the Real Property with 
respect to any other contracts or documents (such as plans and 
specifications) included within the Personal Property; and

         (E)  to recover and retain any monetary damages or other 
benefit inuring to Tenant or the owner of the Real Property through the 
enforcement of any rights, contracts or other documents included within 
the Personal Property (including without limitation the Contract, the 
Development Contracts and other Permitted Encumbrances and any 
agreements, ordinances, regulations and laws concerning any Assessment 
District as defined in the Contract); provided, that to the extent any 
such monetary damages may become payable as compensation for an adverse 
impact on value of the Leased Property, the rights of Landlord and 
Tenant hereunder with respect to the collection and application of such 
monetary damages shall be the same as for condemnation proceeds payable 
because of a taking of all or any part of the Leased Property.

     (d)  No Default or Violation.  The execution, delivery and 
performance by Landlord of this Lease and the Purchase Agreement do not 
and will not constitute a breach or default under any material contract 
or agreement to which Landlord is a party or by which Landlord is bound 
or which affects the Leased Property and do not, to the knowledge of 
Landlord, violate or contravene any law, order, decree, rule or 
regulation to which Landlord is subject.  (As used in this Paragraph 10, 
"Landlord's knowledge" means the present actual knowledge of Lloyd Cox, 
the current officer of Landlord having responsibility for the 
negotiation of this Lease, with due investigation and after consultation 
with Landlord's Parent's representative, Jennifer Cho; but neither Lloyd 
Cox nor Jennifer Cho shall be personally liable for the representations 
or warranties of Landlord made herein.)

     (e)  No Suits.  There are no judicial or administrative actions, 
suits, proceedings or investigations pending or, to Landlord's 
knowledge, threatened that are reasonably likely to affect Landlord's 
ownership of the Leased Property or the validity, enforceability or 
priority of this Lease, and Landlord is not in default with respect to 
any order, writ, injunction, decree or demand of any court or other 
governmental or regulatory authority that could materially and adversely 
affect the business or assets of Landlord or its ownership of the Leased 
Property.  To Landlord's knowledge, no condemnation proceedings are 
pending or threatened against the Leased Property.

     (f)  Organization.  Landlord is duly incorporated and legally 
existing under the laws of Delaware and is duly qualified to do business 
in the State of California.  Landlord has or will obtain on a timely 
basis, at Tenant's expense pursuant to the other provisions of this 
Lease, all requisite power and all governmental certificates of 
authority, licenses, permits, qualifications and other documentation 
necessary to own and lease the Leased Property and to perform its 
obligations under this Lease.

     (g)  Enforceability.  The execution, delivery and performance of 
this Lease and the Purchase Agreement by Landlord are duly authorized, 
are not in contravention of or conflict with any term or provision of 
Landlord's articles of incorporation or bylaws and do not, to Landlord's 
knowledge, require the consent or approval of any governmental body or 
other regulatory authority that has not heretofore been obtained or 
conflict with any Applicable Laws.  This Lease and the Purchase 
Agreement are valid, binding and legally enforceable obligations of 
Landlord except as such enforcement is affected by bankruptcy, 
insolvency and similar laws affecting the rights of creditors, 
generally, and equitable principles of general application; provided, 
Landlord makes no representation or warranty that conditions imposed by 
any state or local Applicable Laws to the purchase, ownership, lease or 
operation of the Leased Property have been satisfied.

     (h)  Existence.  During the Term, Landlord will continuously 
maintain its existence and, after qualifying to do business in the State 
of California if Landlord has not already done so, Landlord will 
continuously maintain its right to do business in that state to the 
extent necessary for the performance of Landlord's obligations 
hereunder.

     (i)  Not a Foreign Person.  Landlord is not a "foreign person" 
within the meaning of Sections 1445 and 7701 of the Code (i.e., Landlord 
is not a non-resident alien, foreign corporation, foreign partnership, 
foreign trust or foreign estate as those terms are defined in the Code 
and regulations promulgated thereunder).

     (j)  Responding to Requests for Information.  Tenant shall have the 
right ask Landlord questions from time to time concerning Landlord's 
financial condition or Landlord's ability to perform under this Lease or 
the Purchase Agreement, to which questions Landlord shall promptly 
respond.  (Such response, however, may be limited to a statement that 
Landlord will not provide requested information.)  Landlord shall notify 
Tenant in writing if, at any time during the Term, Landlord ceases to be 
100% owned, directly or indirectly, by Banque Nationale de Paris.

  11  Assignment and Subletting.

     (a)  Consent Required.  During the Term, without the prior written 
consent of Landlord first had and received, Tenant shall not assign, 
transfer, mortgage, pledge or hypothecate this Lease or any interest of 
Tenant hereunder and shall not sublet all or any part of the Leased 
Property, by operation of law or otherwise; provided, that subject to 
subparagraph 11(c) below:  (1) Tenant shall be entitled to sublet less 
than twenty percent (20%) (computed on the basis of square footage) of 
the useable space in then existing and completed building Improvements, 
if any, so long as (i) any sublease by Tenant is made expressly subject 
and subordinate to the terms hereof, and (ii) such sublease has a term 
equal to or less than the remainder of the then effective Term of this 
Lease; and (2) Tenant shall be entitled to assign or transfer this Lease 
or any interest of Tenant hereunder to an Affiliate of Tenant if both 
Tenant and its Affiliate confirm their joint and several liability 
hereunder by written notice given to Landlord.

     (b)  Standard for Landlord's Consent to Assignments and Certain 
Other Matters.  Consents and approvals of Landlord which are required by 
the preceding subparagraph will not be unreasonably withheld, but Tenant 
acknowledges, without limiting the reasons why Landlord might reasonably 
withhold such consents or approvals, that Landlord's withholding of such 
consent or approval shall be reasonable if Landlord determines in good 
faith that giving the consent or approval may significantly increase 
Landlord's risk of liability for any existing or future environmental 
problem relating to the Leased Property.  Further, Tenant acknowledges 
that Landlord's withholding of such consent or approval shall be 
reasonable if Landlord determines in good faith that giving the consent 
or approval would negate Tenant's representations in this Lease 
regarding ERISA or cause this Lease, the Purchase Agreement or other 
documents described herein or therein (or any exercise of Landlord's 
rights hereunder or thereunder) to constitute a violation of any 
provision of ERISA or of any applicable state statute regulating a Plan 
or Multiemployer Plan.

     (c)  Consent Not a Waiver.  No consent by Landlord to a sale, 
assignment, transfer, mortgage, pledge or hypothecation of this Lease or 
Tenant's interest hereunder, and no assignment or subletting of the 
Leased Property or any part thereof in accordance with this Lease or 
otherwise with Landlord's consent, shall release Tenant from liability 
hereunder; and any such consent shall apply only to the specific 
transaction thereby authorized and shall not relieve Tenant from any 
requirement of obtaining the prior written consent of Landlord to any 
further sale, assignment, transfer, mortgage, pledge or hypothecation of 
this Lease or any interest of Tenant hereunder.

     (d)  Landlord's Assignment.  Unless Tenant or an Applicable 
Purchaser has failed to purchase the Leased Property in accordance with 
the Purchase Agreement and Tenant is thereby in default under the terms 
of the Purchase Agreement, Landlord shall have no right to transfer, 
assign or convey, in whole or in part, the Leased Property or any of its 
rights thereto or under this Lease except by a Permitted Transfer.  
Further, notwithstanding anything to the contrary herein contained, if 
withholding taxes are imposed on the rents and other amounts payable to 
Landlord hereunder because of Landlord's assignment of this Lease to any 
citizen of, or any corporation or other entity formed under the laws of, 
a country other than the United States, Tenant shall not be required to 
compensate Landlord or any such assignee for the withholding tax.

  12  Environmental Indemnification.

     (a)  Indemnity.  Tenant hereby agrees to assume liability for and 
to pay, indemnify, defend, and hold harmless each and every Indemnified 
Party from and against any and all Environmental Losses, subject only to 
the provisions of subparagraph 12(c) below.

     (b)  Assumption of Defense.

          (i)  If an Indemnified Party notifies Tenant of any claim, 
demand, action, administrative or legal proceeding, investigation or 
allegation as to which the indemnity provided for in this Paragraph 12 
applies, Tenant shall assume on behalf of the Indemnified Party and 
conduct with due diligence and in good faith the investigation and 
defense thereof and the response thereto with counsel selected by Tenant 
but reasonably satisfactory to the Indemnified Party; provided, that the 
Indemnified Party shall have the right to be represented by advisory 
counsel of its own selection and at its own expense; and provided 
further, that if any such claim, demand, action, proceeding, 
investigation or allegation involves both Tenant and the Indemnified 
Party and the Indemnified Party shall have been advised in writing by 
counsel that there may be legal defenses available to it which are 
inconsistent with or in addition to those available to Tenant, then the 
Indemnified Party shall have the right to select separate counsel to 
participate in the investigation and defense of and response to such 
claim, demand, action, proceeding, investigation or allegation on its 
own behalf, and Tenant shall pay or reimburse the Indemnified Party for 
all Attorney's Fees incurred by the Indemnified Party because of the 
selection of such separate counsel.

         (ii)  If any claim, demand, action, proceeding, investigation 
or allegation arises as to which the indemnity provided for in this 
Paragraph 12 applies, and Tenant fails to assume promptly (and in any 
event within fifteen (15) days after being notified of the claim, 
demand, action, proceeding, investigation or allegation) the defense of 
the Indemnified Party, then the Indemnified Party may contest (or 
settle, with the prior written consent of Tenant, which consent will not 
be unreasonably withheld) the claim, demand, action, proceeding, 
investigation or allegation at Tenant's expense using counsel selected 
by the Indemnified Party; provided, that after any such failure by 
Tenant which continues for forty-five (45) days or more no such contest 
need be made by the Indemnified Party and settlement or full payment of 
any claim may be made by the Indemnified Party without Tenant's consent 
and without releasing Tenant from any obligations to the Indemnified 
Party under this Paragraph 12 if, in the written opinion of reputable 
counsel to the Indemnified Party, the settlement or payment in full is 
clearly advisable.

     (c)  Notice of Environmental Losses.  If Landlord receives a 
written notice of Environmental Losses that Landlord believes are 
covered by this Paragraph 12, then Landlord shall promptly furnish a 
copy of such notice to Tenant.  The failure to so provide a copy of the 
notice to Tenant shall not excuse Tenant from its obligations under this 
Paragraph 12; provided, that if none of the officers of Tenant and none 
of the employees of Tenant in Tenant's Environmental Health & Safety 
group or in Tenant's Facilities Engineering group (and, in the future, 
no employees taking over responsibilities that such groups now have) are 
aware of the matters described in the notice and such failure by 
Landlord renders unavailable defenses that Tenant might otherwise 
assert, or precludes actions that Tenant might otherwise take, to 
minimize its obligations hereunder, then Tenant shall be excused from 
its obligation to indemnify the Indemnified Parties against assessments, 
fines, costs and expenses, if any, which would not have been incurred 
but for such failure.  For example, if Landlord fails to provide Tenant 
with a copy of a notice of an obligation covered by the indemnity set 
out in subparagraph 12(a) and Tenant is not otherwise already aware of 
such obligation, and if as a result of such failure Landlord becomes 
liable for penalties and interest covered by the indemnity in excess of 
the penalties and interest that would have accrued if Tenant had been 
promptly provided with a copy of the notice, then Tenant will be excused 
from any obligation to Landlord to pay the excess.

     (d)  Rights Cumulative.  The rights of each Indemnified Party under 
this Paragraph 12 shall be in addition to any other rights and remedies 
of such Indemnified Party against Tenant under the other provisions of 
this Lease or under any other document or instrument now or hereafter 
executed by Tenant, or under any Applicable Law or in equity (including, 
without limitation, any right of reimbursement or contribution pursuant 
to CERCLA).

     (e)  Survival of the Indemnity.  Tenant's obligations under this 
Paragraph 12 shall survive the termination or expiration of this Lease.  
All obligations of Tenant under this Paragraph 12 shall be payable upon 
written demand, and any amount due upon demand to any Indemnified Party 
by Tenant which is not paid shall bear interest from the date of such 
written demand at a floating interest rate equal to the Default Rate, 
but in no event in excess of the maximum rate permitted by law.

  13  Inspections and Right of Landlord to Perform, Generally.  

     (a)  During the Term, Landlord and Landlord's representatives may 
(subject to Paragraph 23) enter the Leased Property at any reasonable 
time after five (5) Business Days advance written notice to Tenant for 
the purpose of making inspections or performing any work Landlord is 
authorized to undertake by the next subparagraph.

     (b)  If Tenant fails to perform any act or to take any action which 
hereunder Tenant is required to perform or take, or to pay any money 
which hereunder Tenant is required to pay, and if such failure or action 
constitutes an Event of Default or renders Landlord or any director, 
officer, employee or Affiliate of Landlord at risk of criminal 
prosecution or renders Landlord's interest in the Leased Property or any 
part thereof at risk of forfeiture by forced sale or otherwise, then in 
addition to any other remedies specified herein or otherwise available, 
Landlord may, in Tenant's name or in Landlord's own name, perform or 
cause to be performed such act or take such action or pay such money.  
Any expenses so incurred by Landlord, and any money so paid by Landlord, 
shall be a demand obligation owing by Tenant to Landlord.  Further, 
Landlord, upon making such payment, shall be subrogated to all of the 
rights of the person, corporation or body politic receiving such 
payment.  But nothing herein shall imply any duty upon the part of 
Landlord to do any work which under any provision of this Lease Tenant 
may be required to perform, and the performance thereof by Landlord 
shall not constitute a waiver of Tenant's default.  Landlord may during 
the progress of any such work permitted by Landlord hereunder on or in 
the Leased Property keep and store upon the Leased Property all 
necessary materials, tools, and equipment.  Landlord shall not in any 
event be liable for inconvenience, annoyance, disturbance, loss of 
business, or other damage to Tenant or the subtenants of Tenant by 
reason of making such repairs or the performance of any such work on or 
in the Leased Property, or on account of bringing materials, supplies 
and equipment into or through the Leased Property during the course of 
such work (except for liability in connection with death or injury or 
damage to the property of third parties caused by the Active Negligence, 
gross negligence or wilful misconduct of Landlord or its officers, 
employees, or agents in connection therewith), and the obligations of 
Tenant under this Lease shall not thereby be affected in any manner.

  14  Events of Default.

     (a)  Definition.  Each of the following events shall be deemed to 
be an "Event of Default" by Tenant under this Lease:

          (i)  Tenant shall fail to pay when due any installment of Rent 
due hereunder and such failure shall continue for three (3) Business 
Days after Tenant is notified in writing thereof.

         (ii)  Tenant shall fail to cause any representation or warranty 
of Tenant contained herein that is false or misleading in any material 
respect when made to be made true and not misleading (other than as 
described in the other clauses of this subparagraph 14(a)), or Tenant 
shall fail to comply with any term, provision or covenant of this Lease 
(other than as described in the other clauses of this subparagraph 
14(a)), and in either case shall not cure such failure prior to the 
earlier of (A) thirty (30) days after written notice thereof is sent to 
Tenant or (B) the date any writ or order is issued for the levy or sale 
of any property owned by Landlord (including the Leased Property) or any 
criminal action is instituted against Landlord or any of its directors, 
officers or employees because of such failure; provided, however, that 
so long as no such writ or order is issued and no such criminal action 
is instituted, if such failure is susceptible of cure but cannot with 
reasonable diligence be cured within such thirty day period, and if 
Tenant shall promptly have commenced to cure the same and shall 
thereafter prosecute the curing thereof with reasonable diligence, the 
period within which such failure may be cured shall be extended for such 
further period (not to exceed an additional sixty (60) days) as shall be 
necessary for the curing thereof with reasonable diligence.

        (iii)  Tenant shall fail to comply with any term, provision or 
condition of the Purchase Agreement after the expiration of applicable 
notice and cure periods set forth in the Purchase Agreement.

         (iv)  Tenant shall abandon any significant portion of the 
Leased Property.

          (v)  Tenant shall fail to make any payment or payments of 
principal, premium or interest, of Debt of Tenant described in the next 
sentence when due (taking into consideration the time Tenant may have to 
cure such failure, if any, under the documents governing such Debt).  As 
used in this clause 14(a)(v), "Debt" shall include only Debts of Tenant 
now existing or arising in the future (a) payable to Landlord or any 
Affiliate of Landlord, or (B) payable to any other Person and with 
respect to which $10,000,000 or more is actually due and payable because 
of acceleration or otherwise.

         (vi)  Tenant: (a) shall generally not, or be unable to, or 
shall admit in writing its inability to, pay its debts as such debts 
become due; or (b) shall make an assignment for the benefit of 
creditors, petition or apply to any tribunal for the appointment of a 
custodian, receiver or trustee for it or a substantial part of its 
assets; or (c) shall file any petition or application to commence any 
proceeding under any bankruptcy, reorganization, arrangement, 
readjustment of debt, dissolution or liquidation law or statute of any 
jurisdiction, whether now or hereafter in effect; or (d) shall have had 
any such petition or application filed against it; or (e) by any act or 
omission shall indicate its consent to, approval of or acquiescence in 
any such petition, application or proceeding or order for relief or the 
appointment of a custodian, receiver or trustee for all or any 
substantial part of its property; or (f) shall suffer any such 
custodianship, receivership or trusteeship to continue undischarged for 
a period of sixty (60) days or more.

        (vii)  One or more final non-appealable judgments, decrees or 
orders for the payment of money in excess of $10,000,000 in the 
aggregate shall be rendered against Tenant and such judgments, decrees 
or orders shall continue unsatisfied and in effect for a period of 
thirty (30) consecutive days without Tenant's having obtained an 
agreement (or after the expiration or termination of an agreement) of 
the Persons entitled to enforce such judgment, decrees or orders not to 
enforce the same pending negotiations with Tenant concerning the 
satisfaction or other discharge of the same.

       (viii)  Tenant shall fail to comply with the covenants set forth 
in subparagraph 9(ab) or subparagraph 9(ac).

         (ix)  Tenant shall merge into or consolidate with any other 
entity or permit any other entity to merge into or consolidate with 
Tenant, or Tenant shall directly or indirectly sell, lease, transfer, 
abandon or otherwise dispose of in one or more transactions all or 
substantially all of Tenant's properties other than the Leased Property; 
except that the following shall not constitute an Event of Default: (a) 
any corporation shall merge into or with Tenant and the continuing or 
surviving corporation shall immediately after such event be in 
compliance with the financial covenants set forth in subparagraph 9(ab), 
shall be an Affiliate of F. Hoffmann La-Roche, Ltd., a Swiss corporation 
("Roche"), or any successor of Roche and shall unconditionally assume in 
writing Tenant's obligations under this Lease, the Environmental 
Indemnity Agreement and the Purchase Agreement; and (b) the Tenant shall 
sell, lease or otherwise transfer all or substantially all of Tenant's 
properties other than the Leased Property to another party and the party 
acquiring such properties shall immediately after such event be in 
compliance with the financial covenants set forth in subparagraph 9(ab), 
shall be an Affiliate of Roche or any successor of Roche and shall 
unconditionally assume in writing Tenant's obligations under this Lease, 
the Environmental Indemnity Agreement and the Purchase Agreement.

          (x)  as of the effective date of this Lease, any of the 
representations or warranties of Tenant contained in subparagraph 9(a), 
in subparagraph 9(c), in subparagraph 9(h), in subparagraph 9(i), in 
subparagraph 9(l) or in subparagraph 9(ad)(i) is false or misleading in 
any material respect.

         (xi)  Tenant shall fail to comply with any term, provision or 
condition of any Vacaville Pledge Documents (as defined in the Purchase 
Agreement) after the expiration of applicable notice and cure periods 
set forth in such Vacaville Pledge Documents.

Notwithstanding the foregoing, any Default that could become an Event of 
Default under clause 14(a)(ii) may be cured within the earlier of the 
periods described in clauses (A) and (B) thereof by Tenant's delivery to 
Landlord of a written notice irrevocably exercising Tenant's option 
under the Purchase Agreement to purchase or have an Applicable Purchaser 
purchase Landlord's interest in the Leased Property and designating as 
the Designated Payment Date the next following date which is a Advance 
Date or Base Rental Date and which is at least ten (10) days after the 
date of such notice hereunder; provided, however, Tenant must, as a 
condition to the effectiveness of its cure, on the date so designated as 
the Designated Payment Date tender or have the Applicable Purchaser 
tender to Landlord the full Purchase Price (as defined in the Purchase 
Agreement) and all Rent and all other amounts then due or accrued and 
unpaid hereunder on such Designated Payment Date (including 
reimbursement for any costs incurred by Landlord in connection with the 
applicable Default hereunder, regardless of whether Landlord shall have 
been reimbursed for such costs in whole or in part by Participants or 
any Affiliate of Landlord) and Tenant must also furnish written 
confirmation to Landlord that all indemnities set forth herein 
(including specifically, but without limitation, the indemnities set 
forth in subparagraph 9(x) and the environmental indemnity set forth in 
Paragraph 12 shall survive the payment of such amounts by Tenant to 
Landlord and the conveyance of Landlord's interest in the Leased 
Property to Tenant.

     (b)  Remedies.  When any Event of Default has occurred and is 
continuing, at Landlord's option and without limiting Landlord in the 
exercise of any other right or remedy Landlord may have, and without any 
further demand or notice except as expressly described in this 
subparagraph 14(b), Landlord may institute any remedies available to 
Landlord, which remedies will include the following:

          (i)  By written notice to Tenant, Landlord may terminate 
Tenant's right to possession of the Leased Property.  A notice given in 
connection with unlawful detainer proceedings specifying a time within 
which to cure an Event of Default shall terminate Tenant's right to 
possession if Tenant fails to cure the Event of Default within the time 
specified in the notice.

         (ii)  Upon termination of Tenant's right to possession and 
without further demand or notice, Landlord may re-enter the Leased 
Property and take possession of all improvements, additions, 
alterations, equipment and fixtures thereon and remove any persons in 
possession thereof.  Any property in the Leased Property may be removed 
and stored in a warehouse or elsewhere at the expense and risk of and 
for the account of Tenant.

        (iii)  Upon termination of Tenant's right to possession, this 
Lease shall terminate and Landlord may recover from Tenant:

                a)  The worth at the time of award of the unpaid Rent 
which had been earned at the time of termination;

                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 that 
Tenant proves could have been reasonably avoided;

                c)  The worth at the time of award of the amount by 
which the unpaid Rent through the balance of the scheduled Term (or if 
sooner, through the date a sale is consummated or required under the 
Purchase Agreement) after the time of award exceeds the amount of such 
rental loss that Tenant proves could be reasonably avoided; and

                d)  Any other amount necessary to compensate Landlord 
for all the 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, but not limited 
to, the costs and expenses (including Attorneys' Fees, advertising costs 
and brokers' commissions) of recovering possession of the Leased 
Property, removing persons or property therefrom, placing the Leased 
Property in good order, condition, and repair, preparing and altering 
the Leased Property for reletting, all other costs and expenses of 
reletting, and any loss incurred by Landlord as a result of Tenant's 
failure to perform Tenant's obligations under the Purchase Agreement.

     The "worth at the time of award" of the amounts referred to in 
subparagraph 14(b)(iii)a) and subparagraph 14(b)(iii)b) shall be 
computed by allowing interest at ten percent (10%) per annum or such 
other rate as may be the maximum interest rate then permitted to be 
charged under California law at the time of computation.  The "worth at 
the time of award" of the amount referred to in subparagraph 
14(b)(iii)c) shall be 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 (1%).

                e)  Such other amounts in addition to or in lieu of the 
foregoing as may be permitted from time to time by applicable California 
law.

        (iv)  The Landlord shall have the remedy described in California 
Civil Code Section 1951.4 (lessor may continue lease in force even 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).  Accordingly, even though Tenant has breached this Lease 
and abandoned the Leased Property, this Lease shall continue in effect 
for so long as Landlord does not terminate Tenant's right to possession, 
and Landlord may enforce all of Landlord's rights and remedies under 
this Lease, including the right to recover the Rent as it becomes due 
under this Lease.  Tenant's right to possession shall not be deemed to 
have been terminated by Landlord except pursuant to subparagraph 
14(b)(i) hereof.  The following shall not constitute a termination of 
Tenant's right to possession:

                a)  Acts of maintenance or preservation or efforts to 
relet the Leased Property;

                b)  The appointment of a receiver upon the initiative of 
Landlord to protect Landlord's interest under this Lease; or

                c)  Reasonable withholding of consent to an assignment 
or subletting, or terminating a subletting or assignment by Tenant.

     (c)  Enforceability.  This Paragraph shall be enforceable to the 
maximum extent not prohibited by Applicable Law, and the 
unenforceability of any provision in this Paragraph shall not render any 
other provision unenforceable.

     (d)  Remedies Cumulative.  No right or remedy herein conferred upon 
or reserved to Landlord is intended to be exclusive of any other right 
or remedy, and each and every right and remedy shall be cumulative and 
in addition to any other right or remedy given hereunder or now or 
hereafter existing under Applicable Law or in equity.  In addition to 
other remedies provided in this Lease, Landlord shall be entitled, to 
the extent permitted by Applicable Law, to injunctive relief in case of 
the violation, or attempted or threatened violation, of any of the 
covenants, agreements, conditions or provisions of this Lease to be 
performed by Tenant, or to a decree compelling performance of any of the 
other covenants, agreements, conditions or provisions of this Lease to 
be performed by Tenant, or to any other remedy allowed to Landlord under 
Applicable Law or in equity.  Nothing contained in this Lease shall 
limit or prejudice the right of Landlord to prove for and obtain in 
proceedings for bankruptcy or insolvency of Tenant by reason of the 
termination of this Lease, an amount equal to the maximum allowed by any 
statute or rule of law in effect at the time when, and governing the 
proceedings in which, the damages are to be proved, whether or not the 
amount be greater, equal to, or less than the amount of the loss or 
damages referred to above.  Without limiting the generality of the 
foregoing, nothing contained herein shall modify, limit or impair any of 
the rights and remedies of Landlord under the Environmental Indemnity 
Agreement or the Purchase Agreement.

  15  No Implied Waiver.  The failure of Landlord or Tenant to insist at 
any time upon the strict performance of any covenant or agreement or to 
exercise any option, right, power or remedy contained in this Lease 
shall not be construed as a waiver or a relinquishment thereof for the 
future.  The waiver of or redress for any violation by Landlord or 
Tenant of any term, covenant, agreement or condition contained in this 
Lease shall not prevent a similar subsequent act from constituting a 
violation.  Any express waiver shall affect only the term or condition 
specified in such waiver and only for the time and in the manner 
specifically stated therein.  A receipt by Landlord of any Base Rent or 
other payment hereunder with knowledge of the breach of any covenant or 
agreement of Tenant contained in this Lease shall not be deemed a waiver 
of such breach, and no waiver by either party of any provision of this 
Lease shall be deemed to have been made unless expressed in writing and 
signed by that party.

  16  Default by Landlord.  If Landlord should default in the 
performance of any of its obligations, covenants, agreements, 
conditions, representations or warranties under this Lease, Landlord 
shall have the time reasonably required, but in no event less than 
thirty (30) days, to cure such default after receipt of written notice 
from Tenant specifying such default and specifying what action Tenant 
believes is necessary to cure the default.  If Tenant prevails in any 
litigation brought against Landlord because of Landlord's failure to 
cure a default within the time required by the preceding sentence, then 
Tenant shall be entitled to an award against Landlord for the damages 
proximately caused to Tenant by such default.

  17  Quiet Enjoyment.  Provided Tenant pays the Base Rent and all 
Additional Rent payable hereunder as and when due and payable and keeps 
and fulfills all of the terms, covenants, agreements and conditions to 
be performed by Tenant hereunder, neither Landlord nor any one claiming 
through Landlord (excluding Tenant or anyone claiming through Tenant) 
shall during the Term disturb Tenant's peaceable and quiet enjoyment of 
the Leased Property; however, such enjoyment shall be subject to the 
terms, provisions, covenants, agreements and conditions of this Lease 
and the Permitted Encumbrances and any other claims or encumbrances not 
lawfully asserted through or under Landlord, to which this Lease is 
subject and subordinate as hereinabove set forth.  Any breach by 
Landlord of the foregoing covenant of quiet enjoyment shall, subject to 
the other provisions of this Lease, render Landlord liable to Tenant for 
any monetary damages proximately caused thereby, but as more 
specifically provided in Paragraph 5 above, no such breach shall entitle 
Tenant to terminate this Lease or excuse Tenant from its obligation to 
pay Base Rent and other amounts hereunder.

  18  Surrender Upon Termination.  Unless Tenant or an Applicable 
Purchaser purchases Landlord's entire interest in the Leased Property 
pursuant to the terms of the Purchase Agreement, Tenant shall, upon the 
termination of Tenant's right to occupancy, surrender to Landlord the 
Leased Property, including any buildings, alterations, improvements, 
fixtures, replacements or additions constructed or purchased by Tenant 
with funds advanced by Landlord, but not including movable personal 
property not covered by this Lease, free of all Hazardous Substances 
(including Permitted Hazardous Substances) and tenancies and, to the 
extent required by Landlord, with all Improvements and tangible Personal 
Property in good repair and condition, excepting only (i) ordinary wear 
and tear (provided that the Leased Property shall have been maintained 
as required by the other provisions hereof) and (ii) demolition, 
alterations and additions which are expressly permitted by the terms of 
this Lease and which have been completed by Tenant in a good and 
workmanlike manner in accordance with all Applicable Laws.  Any movable 
furniture or movable personal property belonging to Tenant or any party 
claiming under Tenant, if not removed at the time of such termination 
and if Landlord shall so elect, shall be deemed abandoned and become the 
property of Landlord without any payment or offset therefor.  If 
Landlord shall not so elect, Landlord may remove such property from the 
Leased Property and store it at Tenant's risk and expense.  Tenant shall 
bear the expense of repairing any damage to the Leased Property caused 
by such removal by Landlord or Tenant.  

  19  Holding Over by Tenant.  Should Tenant not purchase Landlord's 
right, title and interest in the Leased Property as provided in the 
Purchase Agreement, but nonetheless continue to hold the Leased Property 
after the termination of this Lease without Landlord's written consent, 
whether such termination occurs by lapse of time or otherwise, such 
holding over shall constitute and be construed as a tenancy from day to 
day only, at a daily Base Rent equal to: (i) Stipulated Loss Value on 
the day in question, times (ii)  the Default Rate for such day; divided 
by (iii) three hundred sixty (360); subject, however, to all of the 
terms, provisions, covenants and agreements on the part of Tenant 
hereunder.  No payments of money by Tenant to Landlord after the 
termination of this Lease shall reinstate, continue or extend the Term 
of this Lease and no extension of this Lease after the termination 
thereof shall be valid unless and until the same shall be reduced to 
writing and signed by both Landlord and Tenant.

  20  Miscellaneous.

     (a)  Notices.  Each provision of this Lease, or of any Applicable 
Laws with reference to the sending, mailing or delivery of any notice or

designate in a notice signed by Tenant's Treasurer or Chief Financial

Construction Advances required of Landlord under this Lease.

        (iii)  All notices, demands and other communications to be made 
hereunder to the parties hereto shall be in writing (at the addresses 
set forth below, or in the case of communications to Participants, at

     (b)  Severability.  If any term or provision of this Lease or the 
application thereof shall to any extent be held by a court of competent 
jurisdiction to be invalid and unenforceable, the remainder of this 
Lease, or the application of such term or provision other than to the 
extent to which it is invalid or unenforceable, shall not be affected 
thereby.

     (c)  No Merger.  There shall be no merger of this Lease or of the 
leasehold estate hereby created with the fee estate in the Leased 
Property or any part thereof by reason of the fact that the same person 
may acquire or hold, directly or indirectly, this Lease or the leasehold 
estate hereby created or any interest in this Lease or in such leasehold 
estate as well as the fee estate in the Leased Property or any interest 
in such fee estate, unless all Persons with an interest in the Leased 
Property that would be adversely affected by any such merger 
specifically agree in writing that such a merger shall occur.

     (d)  NO IMPLIED REPRESENTATIONS BY LANDLORD.  LANDLORD AND 
LANDLORD'S AGENTS HAVE MADE NO REPRESENTATIONS OR PROMISES WITH RESPECT 
TO THE LEASED PROPERTY EXCEPT AS EXPRESSLY SET FORTH HEREIN, AND NO 
RIGHTS, EASEMENTS OR LICENSES ARE ACQUIRED BY TENANT BY IMPLICATION OR 
OTHERWISE EXCEPT AS EXPRESSLY SET FORTH IN THE PROVISIONS OF THIS LEASE 
AND THE PURCHASE AGREEMENT.

     (e)  Entire Agreement.  This Lease and the instruments referred to 
herein supersede any prior negotiations and agreements between the 
parties concerning the Leased Property, including the Prior Lease and 
the Prior Purchase Agreement, but not including the Environmental 
Indemnity Agreement, and no amendment or modification of this Lease 
shall be binding or valid unless expressed in a writing executed by both 
parties hereto.  Tenant ratifies and confirms the Environmental 
Indemnity Agreement as a separate and independent continuing agreement.



     (f)  Binding Effect.  All of the covenants, agreements, terms and 
conditions to be observed and performed by the parties hereto shall be 
applicable to and binding upon their respective successors and, to the 
extent assignment is permitted hereunder, their respective assigns.

     (g)  Time is of the Essence.  Time is of the essence as to all 
obligations of Tenant and Landlord and all notices required of Tenant 
and Landlord under this Lease.

     (h)  Governing Law.  This Lease shall be governed by and construed 
in accordance with the laws of the State of California without regard to 
conflict or choice of laws. 

     (i)  Attorneys' Fees.  If either party to this Lease commences any 
legal action or other proceeding to enforce any of the terms of this 
Lease or the documents or agreements referred to herein, or because of 
any breach of the other party or dispute hereunder or thereunder, the 
successful or prevailing party shall be entitled to recover from the 
nonprevailing party all Attorneys' Fees incurred in connection 
therewith, whether or not such controversy, claim or dispute is 
prosecuted to a final judgment.   Any such Attorneys' Fees incurred by 
either party in enforcing a judgment in its favor under this Lease shall 
be recoverable separately from such judgment, and the obligation for 
such Attorneys' Fees is intended to be severable from other provisions 
of this Lease and not to be merged into any such judgment.

  21  Waiver of Jury Trial.  LANDLORD AND TENANT EACH HEREBY WAIVES ITS 
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED 
UPON OR ARISING OUT OF THIS LEASE OR ANY OTHER DOCUMENT OR DEALINGS 
BETWEEN THEM RELATING TO THIS LEASE OR THE LEASED PROPERTY.  The scope 
of this waiver is intended to be all-encompassing of any and all 
disputes that may be filed in any court and that relate to the subject 
matter of this transaction, including, without limitation, contract 
claims, tort claims, breach of duty claims, and all other common law and 
statutory claims.  Tenant and Landlord each acknowledge that this waiver 
is a material inducement to enter into a business relationship, that 
each has already relied on the waiver in entering into this Lease and 
the other documents referred to herein, and that each will continue to 
rely on the waiver in their related future dealings.  Tenant and 
Landlord each further warrants and represents that it has reviewed this 
waiver with its legal counsel, and that it knowingly and voluntarily 
waives its jury trial rights following consultation with legal counsel.  
THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER 
ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT 
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS LEASE OR TO 
ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS LEASE OR THE LEASED 
PROPERTY.  In the event of litigation, this Lease may be filed as a 
written consent to a trial by the court.

  22  Tax Reporting.  Landlord and Tenant shall report this Lease and 
the Purchase Agreement for federal income tax purposes as a conditional 
sale unless prohibited from doing so by the Internal Revenue Service.  
Similarly, Tenant shall report all interest earned on Escrowed Proceeds 
as Tenant's income for federal and state income tax purposes.  If the 
Internal Revenue Service shall challenge Landlord's characterization of 
this Lease and the Purchase Agreement as a conditional sale for federal 
income tax reporting purposes, Landlord shall notify Tenant in writing 
of such challenge and consider in good faith any reasonable suggestions 
by Tenant about an appropriate response.  In any event, Tenant shall 
(subject only to the limitations set forth in this Paragraph) indemnify, 
defend and hold harmless Landlord from and against all liabilities, 
costs, additional taxes and other expenses, but in any case not any 
Excluded Taxes, that may become due or be asserted because of such 
challenge or because of any resulting recharacterization required by the 
Internal Revenue Service, including any additional taxes that may become 
due upon any sale under the Purchase Agreement to the extent (if any) 
that such additional taxes are not offset by tax savings resulting from 
additional depreciation deductions or other tax benefits to Landlord of 
the recharacterization.  If Landlord receives a written notice of any 
challenge by the Internal Revenue Service that Landlord believes will be 
covered by this Paragraph, then Landlord shall promptly furnish a copy 
of such notice to Tenant.  The failure to so provide a copy of the 
notice to Tenant shall not excuse Tenant from its obligations under this 
Paragraph; provided, that if none of the officers of Tenant and none of 
the employees of Tenant responsible for tax matters are aware of the 
challenge described in the notice and such failure by Landlord renders 
unavailable defenses that Tenant might otherwise assert, or precludes 
actions that Tenant might otherwise take, to minimize its obligations 
hereunder, then Tenant shall be excused from its obligation to indemnify 
Landlord against liabilities, costs, additional taxes and other 
expenses, if any, which would not have been incurred but for such 
failure.  For example, if Landlord fails to provide Tenant with a copy 
of a notice of a challenge by the Internal Revenue Service covered by 
the indemnity set out in this Paragraph and Tenant is not otherwise 
already aware of such challenge, and if as a result of such failure 
Landlord becomes liable for penalties and interest covered by the 
indemnity in excess of the penalties and interest that would have 
accrued if Tenant had been promptly provided with a copy of the notice, 
then Tenant will be excused from any obligation to Landlord to pay the 
excess.

  23  Proprietary Information, Confidentiality and Security.

     (a)  Tenant shall have no obligation to provide proprietary 
information (as defined in the next sentence) to Landlord, except and to 
the extent that (1) Landlord reasonably determines that Landlord cannot 
accomplish the purposes of Landlord's inspection of the Leased Property 
pursuant to the various provisions hereof without evaluating such 
information, and (2) before conducting any inspections of the Leased 
Property permitted hereunder Landlord shall, if requested by Tenant, 
confirm and ratify the confidentiality agreements covering such 
proprietary information set forth in the next subparagraph.  For 
purposes of this Lease "proprietary information" includes Tenant's 
intellectual property, trade secrets and other confidential information 
of value to Tenant about, among other things, Tenant's manufacturing 
processes, products, marketing and corporate strategies, but in no event 
will "proprietary information" include any disclosure of substances and 
materials (and their chemical composition) which are or previously have 
been present in, on or under the Leased Property at the time of any 
inspections by Landlord, nor will "proprietary information" include any 
additional disclosures reasonably required to permit Landlord to 
determine whether the presence of such substances and materials has 
constituted a violation of Environmental Laws.  In addition, under no 
circumstances shall Tenant have any obligation to disclose to Landlord 
or any other party any proprietary information of Tenant (including, 
without limitation, any pending applications for patents or trademarks, 
any research and design and any trade secrets) except if and to the 
limited extent reasonably necessary to comply with the express 
provisions of this Lease.  

     (b)  Landlord agrees to use reasonable precautions to keep 
confidential any proprietary information that Landlord may receive from 
Tenant or otherwise discover with respect to Tenant or Tenant's business 
pursuant to this Lease or any investigation by Landlord hereunder, 
except for disclosures: (i) specifically and previously authorized in 
writing by Tenant; (ii) to any assignee of Landlord as to any interest 
in the Leased Property so long as such assignee has agreed in writing to 
use its reasonable efforts to keep such information confidential in 
accordance with the terms of this paragraph; (iii) to legal counsel, 
accountants, auditors, environmental consultants and other professional 
advisors to Landlord so long as Landlord shall inform such persons in 
writing (if practicable) of the confidential nature of such information 
and shall direct them to treat such information confidentially; (iv) to 
regulatory officials having jurisdiction over Landlord or Landlord's 
Parent (provided that the disclosing party shall request confidential 
treatment of the disclosed information, if practicable); (v) as required 
by legal process (provided that the disclosing party shall request 
confidential treatment of the disclosed information, if practicable); 
(vi) of information which has previously become publicly available 
through the actions or inactions of a person other than Landlord not, to 
Landlord's knowledge, in breach of an obligation of confidentiality to 
Tenant; and (vii) to any Participant so long as the Participant is bound 
by and has not repudiated the confidentiality provision concerning 
Tenant's proprietary information set forth in the participation 
agreement between Landlord and such Participant.

     (c)  So long as Tenant remains in possession of the Leased 
Property, Landlord or Landlord's representative will, before making any 
inspection or performing any work on the Leased Property authorized by 
this Lease, if then requested to do so by Tenant to maintain Tenant's 
security: (i) sign in at Tenant's security or information desk if Tenant 
has such a desk on the premises, (ii) wear a visitor's badge or other 
reasonable identification, (iii) permit an employee of Tenant to observe 
such inspection or work, and (iv) comply with other similar reasonable 
nondiscriminatory security requirements of Tenant that do not, 
individually or in the aggregate, significantly interfere with 
inspections or work of Landlord authorized by this Lease.

Attention:  Lloyd Cox

     Re:  Assignment of Construction Contract

Ladies and Gentlemen:

     The undersigned hereby confirms, warrants and represents to BNP 
Leasing Corporation, a Delaware corporation ("BNP"), and covenants with 
BNP as follows:

  1.  The undersigned has entered into that certain [**Construction 
Contract] (the "Construction Contract") by and between the undersigned 
and Genentech, Inc. ("Tenant") dated, 199__ for the construction of the 
manufacturing complex to be constructed on the Vacaville campus leased 
by Tenant (the "Improvements") located on the land described in Exhibit 
A attached hereto and made a part hereof for all purposes (the "Land" 
and, together with the Improvements and any other improvements now on or 
constructed in the future on the Land, being collectively herein 
referred to as the "Project"). 

  2.  The undersigned has been advised that BNP owns the Land. 

  3.  The undersigned has also received a copy of the Amended and 
Restated Lease Agreement dated as of December 8, 1995 (the "Lease"), 
pursuant to which BNP is leasing the Project to Tenant, and BNP has 
agreed, subject to the terms and conditions of the Lease, to provide a 
construction allowance for Tenant's construction of the Improvements.  
The Lease also requires Tenant to fulfill all obligations of "Genentech" 
under the Construction Contract and related documents and to indemnify 
BNP against any liability arising thereunder, all as more particularly 
provided in the Lease, reference to which is hereby made for all 
purposes.

  4.  A complete and correct copy of the Construction Contract is 
attached to this letter.  The Construction Contract is in full force and 
effect and has not been modified or amended.

  5.  The undersigned has not sent or received any notice of default to 
or from Tenant or any other notice to or from Tenant for the purpose of 
terminating the Construction Contract, nor is there any existing 
circumstance or event which, but for the elapse of time or otherwise, 
would constitute a default by the undersigned or "Genentech" under the 
Construction Contract.

     The undersigned acknowledges and agrees that:

     a)  BNP shall not be held liable for, and the undersigned shall not 
assert, any claims, demands or liabilities against BNP or, except for 
any statutory stop notice or lien rights, against the Project arising 
under or in any way relating to the Construction Contract; provided, 
this paragraph will not prohibit the undersigned from asserting any 
claims or making demands under the Construction Contract if BNP elects 
in writing, pursuant to Paragraph b) below, to assume the Construction 
Contract in the event Tenant's right to possession of the Land is 
terminated, in which event BNP shall be liable thereunder for (but only 
for) any acts or omissions on the part of BNP occurring after the date 
on which BNP notifies the undersigned of BNP's election to assume the 
Construction Contract.

     b)  Upon any termination of Tenant's right to possession of the 
Project under the Lease, including but not limited to any eviction of 
Tenant resulting from an Event of Default (as defined in the Lease), BNP 
may, by notice to the undersigned and without the necessity of the 
execution of any other document, assume Tenant's rights and obligations 
under the Construction Contract, cure any defaults by Tenant thereunder 
and enforce the Construction Contract and all rights of "Genentech" 
thereunder.  Within ten (10) days of receiving notice from BNP that 
Tenant's right to possession has been terminated, the undersigned shall 
send to BNP a written estoppel letter stating: (i) that the undersigned 
has not performed any act or executed any other instrument which 
invalidates or modifies the Construction Contract in whole or in part 
(or, if so, the nature of such modification); (ii) that the Construction 
Contract is valid and subsisting and in full force and effect; (iii) 
that there are no defaults or events of default then existing under the 
Construction Contract and no event has occurred which with the passage 
of time or the giving of notice, or both, would constitute such a 
default or event of default under the Construction Contract (or, if 
there is a default, the nature of such default in detail); (iv) that the 
construction contemplated by the Construction Contract is proceeding in 
a satisfactory manner in all material respects (or if not, a detailed 
description of all significant problems with the progress of 
construction); (v) a reasonably detailed report of the then critical 
dates projected by the undersigned for work and deliveries required to 
complete the Project; (vi) the total amount paid for construction 
through the date of the letter; (vii) the estimated total cost of 
completing such construction as of the date of the letter, together with 
a current draw schedule; and (viii) any other information BNP may 
request to allow it to decide whether to assume the Construction 
Contract.  BNP shall have thirty (30) days from receipt of such written 
certificate containing all such requested information to decide whether 
to assume the Construction Contract, but during such thirty (30) day 
period Contractor may suspend work as reasonably required to mitigate 
any further losses it may suffer under the Construction Contract until 
such time as BNP provides written notice of BNP's election to assume the 
Construction Contract.  If BNP fails to provide written notice to 
Contractor of BNP's election to assume the Construction Contract within 
such thirty (30) day period, the undersigned agrees that BNP shall not 
be liable for (and the undersigned shall not assert or bring any action 
against BNP or, except for any statutory stop notice or lien rights not 
waived, against the Land or improvements thereon for) any damages or 
other amounts resulting from the breach or termination of the 
Construction Contract or under any other theory of liability of any kind 
or nature, but rather the undersigned shall look solely to Tenant and 
any statutory stop notice or lien rights not waived for the recovery of 
any such damages or other amounts. 

     c)  Following the termination of Tenant's right to possession of 
the Project under the Lease, if BNP notifies the undersigned that BNP 
shall not assume the Construction Contract pursuant to the preceding 
paragraph, or if BNP fails to provide written notice of its election to 
assume the Construction Contract within the thirty (30) days described 
in the preceding paragraph, the undersigned shall immediately 
discontinue the work under the Construction Contract and remove its 
personnel from the Project, and BNP shall be entitled to take exclusive 
possession of the Project and all or any part of the equipment and 
materials delivered or en route to the Project.  The undersigned shall 
also, upon request by BNP, deliver and assign to BNP all plans and 
specifications and other contract documents previously delivered to the 
undersigned, all other material relating to the work which belongs to 
BNP or Tenant, and all papers and documents relating to governmental 
permits, orders placed, bills and invoices, lien releases and financial 
management under the Construction Contract; provided, that BNP pays or 
reimburses Contractor for its copying costs and other reasonable out of 
pocket expenses in complying with such request; and, provided, further, 
that if Contractor has only one original counterpart of any contract or 
other document that it needs in connection with any claim, demand, or 
the exercise of any rights or remedies the undersigned may have against 
the Tenant, whether provided by law, the Construction Contract or 
otherwise, then Contractor may retain such original counterpart and 
deliver only a copy of it to BNP.  Notwithstanding the undersigned's 
receipt of any notice from BNP that BNP declines to assume the 
Construction Contract, the undersigned shall for a period not to exceed 
fifteen (15) days after receipt of such notice take such steps, at BNP's 
expense, as are reasonably necessary to preserve and protect work 
completed and in progress and to protect materials, equipment and 
supplies at the site or in transit.

     d)  No action taken by BNP or the undersigned with respect to the 
Construction Contract shall prejudice any other rights or remedies of 
BNP or the undersigned provided by law, by the Lease , by the 
Construction Contract or otherwise against Tenant. 

     e)  The undersigned agrees promptly to notify BNP of any aterial 
default or claimed material default by Tenant under the Construction 
Contract, describing with particularity the default and the action the 
undersigned believes is necessary to cure the same.  The undersigned 
will send any such notice to BNP prominently marked "URGENT - NOTICE OF 
TENANT'S DEFAULT UNDER CONSTRUCTION AGREEMENT WITH _______________ - 
___________ CALIFORNIA" at the address specified for notice below (or at 
such other addresses as BNP shall designate in notice sent to the 
undersigned), by certified or registered mail, return receipt requested.  
Following receipt of such notice, the undersigned will permit BNP or its 
designee to cure any such default within the time period reasonably 
required for such cure, but in no event less than thirty (30) days.  
Pending any such cure by BNP, Contractor may, to the extent (if any) 
permitted by the Construction Contract itself, suspend work under the 
Construction Contract unless BNP elects to fund the ongoing construction 
activities of Contractor during the period before the cure is complete.  
If it is necessary or helpful to take possession of all or any portion 
of the Project to cure a default by Tenant under the Construction 
Contract, the time permitted by the undersigned for cure by BNP will 
include the time necessary to terminate Tenant's right to possession of 
the Project and evict Tenant, provided that BNP commences the steps 
required to exercise such right within sixty (60) days after it is 
entitled to do so under the terms of the Lease and applicable law.  If 
the undersigned incurs additional costs due to an extension of any cure 
period under the Construction Contract by reason of the foregoing, the 
undersigned shall be entitled to an equitable adjustment to the price of 
the Construction Contract for such additional costs.  Similarly, to the 
extent that Contractor's work is actually delayed by the extension of 
cure periods under the Construction Contract pursuant to the foregoing 
provisions, Contractor shall be entitled to an equitable extension of 
deadlines and time schedules established by the Construction Contract.

     f)  Any notice or communication required or permitted hereunder 
shall be given in writing, sent by (a) personal delivery or (b) 
expedited delivery service with proof of delivery or (c) United States 
mail, postage prepaid, registered or certified mail or (d) telegram, 
telex or telecopy, addressed as follows:

accuracy of the representations made herein, in connection with BNP's 
decision to advance funds for construction under the Lease with Tenant.

                                    Very truly yours,

     Re:  Assignment of [Architects/Engineers Agreement]

Ladies and Gentlemen:

     The undersigned hereby confirms, warrants and represents to BNP 
Leasing Corporation, a Delaware corporation ("BNP"), and covenants with 
BNP as follows:

  1.  The undersigned has entered into that certain 
[**Architects/Engineers Agreement] (the "Agreement") by and between the 
undersigned and Genentech, Inc. ("Tenant") dated, 199__ for the 
[**design] of the manufacturing complex to be constructed on the 
Vacaville campus leased by Applied (the "Improvements") located on the 
land described in Exhibit A attached hereto and made a part hereof for 
all purposes (the "Land" and, together with the Improvements and any 
other improvements now on or constructed in the future on the Land, 
being collectively referred to herein as the "Project"). 

  2.  The undersigned has been advised that BNP owns the Land. 

  3.  The undersigned has also received a copy of the Amended and 
Restated Lease Agreement dated as of December 8, 1995 (the "Lease"), 
pursuant to which BNP is leasing the Project to Tenant, and BNP has 
agreed, subject to the terms and conditions of the Lease, to provide a 
construction allowance for Tenant's construction of the Improvements.  
The Lease also requires Tenant to fulfill all obligations of "Genentech" 
under the Agreement and related documents and to indemnify BNP against 
any liability arising thereunder, all as more particularly provided in 
the Lease, reference to which is hereby made for all purposes.

  4.  complete and correct copy of the Agreement is attached to this 
letter.  The Agreement is in full force and effect and has not been 
modified or amended.

  5.  The undersigned has not sent or received any notice of default to 
or from Tenant or any other notice to or from Tenant for the purpose of 
terminating the Agreement, nor is there any existing circumstance or 
event which, but for the elapse of time or otherwise, would constitute a 
default by the undersigned or "Genentech" under the Agreement.

      The undersigned acknowledges and agrees that:

     a)  BNP shall not be held liable for, and the undersigned shall not 
assert, any claims, demands or liabilities against BNP or, except for 
any statutory stop notice or lien rights, against the Project arising 
under or in any way relating to the Agreement; provided, this paragraph 
will not prohibit the undersigned from asserting any claims or making 
demands under the Agreement if BNP elects in writing, pursuant to 
Paragraph b) below, to assume the Agreement in the event Tenant's right 
to possession of the Land is terminated, in which event BNP shall be 
liable thereunder for (but only for) any acts or omissions on the part 
of BNP occurring after the date on which BNP notifies the undersigned of 
BNP's election to assume the Agreement.

     b)  Upon any termination of Tenant's right to possession of the 
Project under the Lease, including but not limited to any eviction of 
Tenant resulting from an Event of Default (as defined in the Lease), BNP 
may, by notice to the undersigned and without the necessity of the 
execution of any other document, assume Tenant's rights and obligations 
under the Agreement, cure any defaults by Tenant thereunder and enforce 
the Agreement and all rights of "Genentech" thereunder.  Within ten (10) 
days of receiving notice from BNP that Tenant's right to possession has 
been terminated, the undersigned shall send to BNP a written estoppel 
letter stating: (i) that the undersigned has not performed any act or 
executed any other instrument which invalidates or modifies the 
Agreement in whole or in part (or, if so, the nature of such 
modification); (ii) that the Agreement is valid and subsisting and in 
full force and effect; (iii) that there are no defaults or events of 
default then existing under the Agreement and no event has occurred 
which with the passage of time or the giving of notice, or both, would 
constitute such a default or event of default under the Agreement (or, 
if there is a default, the nature of such default in detail); (iv) that 
the construction contemplated by the Agreement is proceeding in a 
satisfactory manner in all material respects (or if not, a detailed 
description of all significant problems with the progress of 
construction); (v) a reasonably detailed report of the then critical 
dates projected by the undersigned for work and deliveries required to 
complete the Project; (vi) the total amount paid for construction 
through the date of the letter; (vii) the estimated total cost of 
completing such construction as of the date of the letter, together with 
a current draw schedule; and (viii) any other information BNP may 
request to allow it to decide whether to assume the Agreement.  BNP 
shall have thirty (30) days from receipt of such written certificate 
containing all such requested information to decide whether to assume 
the Agreement.  If BNP fails to assume the Agreement within such time, 
the undersigned agrees that BNP shall not be liable for (and the 
undersigned shall not assert or bring any action against BNP or, except 
for any statutory stop notice or lien rights not waived, against the 
Land or improvements thereon for) any damages or other amounts resulting 
from the breach or termination of the Agreement or under any other 
theory of liability of any kind or nature, but rather the undersigned 
shall look solely to Tenant and any statutory stop notice or lien rights 
not waived for the recovery of any such damages or other amounts. 

     c)  If BNP notifies the undersigned that BNP shall not assume the 
Agreement pursuant to the preceding paragraph following the termination 
of Tenant's right to possession of the Project under the Lease, the 
undersigned shall immediately discontinue the work under the Agreement 
and remove its personnel from the Project, and BNP shall be entitled to 
take exclusive possession of the Project and all or any part of the 
equipment and materials delivered or en route to the Project.  The 
undersigned shall also, upon request by BNP, deliver and assign to BNP 
all plans and specifications and other contract documents previously 
delivered to the undersigned (except that the undersigned may keep an 
original set of the Agreement and other contract documents executed by 
Tenant), all other material relating to the work which belongs to BNP or 
Tenant, and all papers and documents relating to governmental permits, 
orders placed, bills and invoices, lien releases and financial 
management under the Agreement.  Notwithstanding the undersigned's 
receipt of any notice from BNP that BNP declines to assume the 
Agreement, the undersigned shall for a period not to exceed fifteen (15) 
days after receipt of such notice take such steps, at BNP's expense, as 
are reasonably necessary to preserve and protect work completed and in 
progress and to protect materials, equipment and supplies at the site or 
in transit.

     d)  No action taken by BNP or the undersigned with respect to the 
Agreement shall prejudice any other rights or remedies of BNP or the 
undersigned provided by law, by the Lease, by the Agreement or otherwise 
against Tenant. 

     e)  The undersigned agrees promptly to notify BNP of any material 
default or claimed material default by Tenant under the Agreement, 
describing with particularity the default and the action the undersigned 
believes is necessary to cure the same.  The undersigned will send any 
such notice to BNP prominently marked "URGENT - NOTICE OF TENANT'S 
DEFAULT UNDER AGREEMENT WITH _______________ - ___________ CALIFORNIA" 
at the address specified for notice below (or at such other addresses as 
BNP shall designate in notice sent to the undersigned), by certified or 
registered mail, return receipt requested.  Following receipt of such 
notice, the undersigned will permit BNP or its designee to cure any such 
default within the time period reasonably required for such cure, but in 
no event less than thirty (30) days.  If it is necessary or helpful to 
take possession of all or any portion of the Project to cure a default 
by Tenant under the Agreement, the time permitted by the undersigned for 
cure by BNP will include the time necessary to terminate Tenant's right 
to possession of the Project and evict Tenant, provided that BNP 
commences the steps required to exercise such right within sixty (60) 
days after it is entitled to do so under the terms of the Lease and 
applicable law.

     f)  Any notice or communication required or permitted hereunder 
shall be given in writing, sent by (a) personal delivery or (b) 
expedited delivery service with proof of delivery or (c) United States 
mail, postage prepaid, registered or certified mail or (d) telegram, 
telex or telecopy, addressed as follows:

     Re:  Construction Advance Request No. __________
          by Genentech, Inc.

Ladies and Gentlemen:

     Reference is made to the Amended and Restated Lease Agreement 
between BNP Leasing Corporation (herein "Landlord") and Genentech, Inc. 
(herein "Genentech") dated as of December 8, 1995 (herein "the Lease").  
Capitalized terms defined in the Lease and used but not defined in this 
letter are intended to have the meanings assigned  to them in the Lease.

     Genentech hereby makes request for a Construction Advance in the 
amount of $________________ (herein the "Current Advance"). Included 
herewith are:

  1.  An Application and Certificate for Payment based on AIA Form G702 
(herein the "Contractor's Application") from Genentech's general 
contractor or construction manager, attached to which is a schedule of 
values listing all subcontractors, suppliers and other parties to whom 
the general contractor or construction manager has or will make payments 
from the draw requested in the Contractor's Application.  The 
Contractor's Application evidences an obligation incurred by (and 
previously paid by) Genentech for construction of Improvements and for 
which Genentech is entitled to reimbursement from the Current Advance.

  2.  A list of any costs paid by Genentech, other than to the general 
contractor or construction manager, for which Genentech is entitled to 
reimbursement from the proceeds of the Current Advance (herein the 
"Other Costs List").

  3.  Invoices and requests for payments from the subcontractors and 
others entitled to payment from the general contractor or construction 
manager for construction and related work covered by the Contractor's 
Application; excluding, however, invoices or requests from some or all 
subcontractors and others that, according to the Contractor's 
Application, are to be paid less than $500,000 from the draw requested 
in Contractor's Application.  Such invoices and requests for payments 
are consistent with the detail shown in the schedule of values attached 
to the Contractor's Application.


  4.  Invoices or other evidence of the costs (if any) included in the 
Other Costs List.

  5.  A list of any "checks on hold" (i.e., payments withheld from 
subcontractors or suppliers by Tenant's general contractor or 
construction manager because of some defect or deficiency in the payee's 
request for payment or in the work or materials provided by the payee) 
in excess of $100,000.

  6.  An up-to-date list of the names and addresses of any 
subcontractors that have actually filed a claim of lien against the 
Leased Property, together with, to the extent not already provided with 
a prior request for a Construction Advance, a copy of the claim of lien 
filed.

  7.  A certification of an officer of Genentech as required by 
Paragraph 6(c)(viii) of the Lease.

     We hereby confirm that Landlord will not be responsible for the 
application of any funds advanced to Genentech or to any other party at 
our request.

                                    Sincerely,

                                    Genentech, Inc.

     c)  each Construction Project which has commenced but not yet been

in a good and workmanlike manner and substantially in accordance with 
the requirements of the Lease and all Applicable Laws and Genentech has 
corrected or is diligently pursuing the correction of any significant 
defect in such construction,

     d)  all costs and expenses for which Genentech is requesting 
reimbursement by the Construction Advance referenced above constitute 
actual costs and expenses incurred by Genentech for a Construction 
Project, and

     e)  to the knowledge of Genentech, liens (if any) now being 
asserted against the Leased Property by Potential Lien Claimants do not 
in the aggregate secure or allegedly secure more that $5,000,000 of 
claims.  (As used in this certificate a lien will be considered as 
"being asserted" if a claim of lien relating thereto shall have been 
recorded and not discharged by payment or settlement.)

Capitalized terms used herein which are defined in the Lease but not in 
this Certificate shall have the meanings assigned to them in the Lease.

In witness whereof, this Certificate is executed by an officer of

           DESCRIPTION OF INITIAL CONSTRUCTION PROJECT

The following description has been provided by Tenant to Landlord:

GENERAL DESCRIPTION

The "initial Construction Project" will consist of the design, 
construction, validation, start-up, and operation of a Bulk 
Manufacturing Facility (hereafter referred to as the Manufacturing 
Facility) for mammalian cell culture based products substantially in 
accordance with the site plan attached to and made a part of this 
Schedule.  The Manufacturing Facility is being designed to use large-
scale cell culture (12,000 L production fermenters) and purification 
technologies similar to those used at Genentech's South San Francisco 
facilities.  The facility will initially be licensed for the manufacture 
of monoclonal antibody-based proteins which are intended for worldwide 
distribution.  The facility design criteria are based on the clinical 
processes developed for rhuMAb HER2, rhuMAb-E25, TNFR-rigG, and C2B8 
with batch sizes in the range of 1 to 9 kg.  It is anticipated that the 
Vacaville facility will be available for production of qualification 
lots by mid-1998.

The site encompasses approximately 100 acres and the planned buildings 
will occupy approximately 30 acres.  The support buildings will include 
a warehouse, a quality/administration building, a facility services 
building, and a central processing utility plant.

The Vacaville location was chosen primarily because of the reduced risk 
of earthquake potential, presence of skilled labor resources, adequate 
space for future growth, and proximity to current Genentech operations.  
The City of Vacaville has experience in working with biotechnology firms 
as well as an established infrastructure required to support such an 
endeavor.

Possible future requirements for the new site that have been identified 
but will not be addressed at this time are:  a bacterial manufacturing 
facility; a second cell culture facility; pharmaceutical filling, 
labeling, and packaging; and the expansion of the existing warehousing 
and quality operations.  No current provision is made for these future 
requirements other than the purchase of land and some utility capacity.


MANUFACTURING FACILITY

The Manufacturing Facility is being designed for the production of 
multiple products on a campaigned basis.  The frozen bulk drug substance 
will be transferred to Genentech facilities in South San Francisco for 
further processing.  The capacity will be approximately one- to two-fold 
Genentech's current bulk product production capacity in South San 
Francisco.

The Manufacturing Facility is planned to be approximately 170,000 ft2.  
The facility will be a three floor building with dedicated manufacturing 
areas.  The utilities will be located in the center of the building 
spanning the three floors, and will separate the various processing 
areas.



WAREHOUSE

The warehouse will be a two-floor building of approximately 45,000 ft2, 
and will be connected to the Manufacturing Facility on the second floor 
by an environmentally controlled corridor to facilitate the movement of 
raw materials and frozen bulk drug substance tanks.  In addition to 
storage of released raw materials the warehouse will include Raw 
material weigh rooms.


QUALITY/ADMINISTRATION BUILDING

The quality/administration building will house Quality Assurance, 
Quality Control laboratories, manufacturing science laboratory support, 
and offices.  The QC laboratories will perform in-process testing, 
environmental monitoring and water analysis.
