independent covenants and agreements, all Monetary Obligations shall 
continue to be payable in all events (or, in lieu thereof, Tenant shall 
pay amounts equal thereto), and the obligations of Tenant hereunder shall

Lease.  All Rent payable by Tenant hereunder shall constitute "rent" for 
all purposes (including Section 502(b)(6) of the Federal Bankruptcy 
Code).

        (d)     Except as otherwise expressly provided herein, Tenant shall 
have no right and hereby waives all rights which it may have under any 
Law (i) to quit, terminate or surrender this Lease or any of the Leased

        9.      Payment of Impositions.

        (a)     Tenant shall, not later than the due date thereof, or at 
least five (5) days prior to the day before any fine, interest, penalty 
or cost may be added thereto or imposed, or at least five (5) days prior 
to the day any lien may be filed for the non-payment thereof (if such day 
is used to determine the due date of the respective item), pay and 
discharge all taxes (including real and personal property, franchise, 
sales and rent taxes), all charges for any easement or agreement 
maintained for the benefit of any of  the Leased Premises, all 
assessments and levies, all permit, inspection and license fees, all 
rents and charges for water, sewer, utility and communication services 
relating to any of the Leased Premises, all ground rents and all other 
public charges whether of a like or different nature, even if unforeseen 
or extraordinary, imposed upon or assessed against (i) Tenant, (ii) any 
of the Leased Premises, including any increases in real estate taxes from 
a reassessment of the Leased Premises by the applicable taxing authority 
as a result of any transfer of the Leased Premises (A) to any affiliate 
of Landlord or Landlord's parent of which Landlord's parent directly or 
indirectly owns beneficially more than fifty percent (50%) or (B) to 
Landlord's parent so long as in any such case Tenant has an opportunity 
to review and comment upon the structure of such transfer prior to the 
occurrence thereof, (iii) Landlord as a result of or arising in respect 
of the acquisition, ownership, occupancy, leasing, use, possession or 
sale of any of the Leased Premises, any activity conducted on any of the 
Leased Premises, or the Rent, or (iv) any Lender by reason of any Note, 
Mortgage, Assignment or other document evidencing or securing a Loan and 
which (as to this clause (iv)) Landlord has agreed to pay (collectively, 
the "Impositions"); provided, that nothing herein shall obligate Tenant 
to pay (A) income, excess profits or other taxes of Landlord (or Lender) 
which are determined on the basis of Landlord's (or Lender's) net income 
or net worth (unless such taxes are a substitute for any then existing 
tax, assessment or other charge upon or with respect to the Leased 
Premises which, if it were in effect, would be payable by Tenant under 
the provisions hereof or by the terms of such tax, assessment or other 
charge), (B) any estate, inheritance, succession, gift or similar tax 
imposed on Landlord or Lender, (C) any capital gains tax imposed on 
Landlord in connection with the sale of the Leased Premises to any Person 
or (D) any increases in real estate taxes from a reassessment of the 
Leased Premises by the applicable taxing authority as a result of (x) any 
sale or transfer of the Leased Premises or, (y) any sale or transfer of 
ownership interests by any member of Landlord, except as provided in (ii) 
above.  If any Imposition may be paid in installments without interest or 
penalty, Tenant shall have the option to pay such Imposition in 
installments; in such event, Tenant shall be liable only for those 
installments which accrue or become due and payable during the Term.  
Tenant shall prepare and file all tax reports required by governmental 
authorities which relate to the Impositions.  Tenant shall deliver to 
Landlord (1) copies of all settlements and notices pertaining to the 
Impositions which may be issued by any governmental authority within ten 
(10) days after Tenant's receipt thereof, (2) receipts for payment of all 
taxes required to be paid by Tenant hereunder within thirty (30) days 
after the due date thereof and (3) receipts for payment of all other 
Impositions within ten (10) days after Landlord's request therefor.  Any 
refunds of Impositions attributable to any period during the Term shall 
be payable to, and shall be the property of, Tenant.

        (b)     Landlord shall have the right at any time following the 
occurrence and during the continuation of an Event of Default to require 
Tenant to pay to Landlord (or Lender if Landlord is so required pursuant 
to the terms of the Mortgage) an additional monthly sum (the "Escrow 
Payments") sufficient to pay the Escrow Charges (as hereinafter defined) 
as they become due.  As used herein, "Escrow Charges" shall mean real 
estate taxes on the Leased Premises or payments in lieu thereof and 
premiums on any insurance required by this Lease.  Landlord shall 
determine the amount of the Escrow Charges and of each Escrow Payment.  
As long as the Escrow Payments are being held by Landlord and not Lender, 
or if Lender shall hold the Escrow Payments and shall so agree,  the 
Escrow Payments shall not be commingled with other funds of Landlord or 
other Persons and interest shall accrue thereon for the benefit of 
Tenant, from the date such monies are received by or on behalf of 
Landlord to the date such monies are disbursed to pay Escrow Charges.  
Landlord or Lender, as the case may be, shall apply the Escrow Payments 
to the payment of the Escrow Charges in such order or priority as 
Landlord shall determine or as required by law.  If at any time the 
Escrow Payments theretofore paid to Landlord or Lender, as the case may 
be, shall be insufficient for the payment of the Escrow Charges, Tenant, 
within ten (10) days after Landlord's demand therefor, which shall 
include written verification of such deficiency, shall pay the amount of 
the deficiency to Landlord.

        10.     Compliance with Laws and Easement Agreements; Environmental 
Matters.

        (a)     Tenant shall, at its sole expense, be in material compliance 
with and conform to, and cause any other Person occupying any part of the 
Leased Premises to be in material compliance with and conform to, all 
Insurance Requirements and Legal Requirements (except that Tenant and the 
Leased Premises shall be in absolute compliance with all applicable 
Environmental Laws).  Tenant shall not at any time (i) cause, permit or 
suffer to occur any material Environmental Violation or (ii) permit any 
sublessee, assignee or other Person occupying the Leased Premises under 
or through Tenant to cause, permit or suffer to occur any material 
Environmental Violation and, at the request of Landlord or Lender, Tenant 
shall promptly remediate or undertake any other appropriate response 
action to correct any existing Environmental Violation, however 
immaterial.

        (b)     Tenant, at its sole cost and expense, will at all times 
promptly and faithfully abide by, discharge and perform all of the 
covenants, conditions and agreements contained in any Easement Agreement 
on the part of Landlord or other occupier of the Leased Premises, to be 
kept and performed thereunder.  Tenant will not alter, modify, amend or 
terminate any Easement Agreement, give any consent or approval 
thereunder, or enter into any new Easement Agreement without, in each 
case, the prior written consent of Landlord, which consent shall not be 
unreasonably withheld.  Any such new Easement Agreement shall 
automatically be a Permitted Encumbrance.

        (c)     In connection with the refinancing of the Initial Loan or as 
reasonably requested by a Lender and in any other case not more 
frequently than once every three (3) years or at any other time that, in 
the opinion of Landlord or Lender, a reasonable basis exists to believe 
that an Environmental Violation exists or a condition that could be 
reasonably expected to result in an Environmental Violation exists, upon 
prior written notice from Landlord or Lender, Tenant shall permit such 
persons as Landlord or Lender may designate ("Site Reviewers") to visit 
the Leased Premises at reasonable times agreed to by Tenant and perform, 
as agents of Tenant, environmental site investigations and assessments 
("Site Assessments") on the Leased Premises for the purpose of 
investigating the Leased Premises.  In addition to the permitted Site 
Assessments, the Site Reviewers shall have the right to  obtain from 
Tenant information reasonably necessary to update any Site Assessment.  
Such Site Assessments may include both above and below the ground testing 
for Environmental Violations and such other tests as may be reasonably 
necessary, in the opinion of the Site Reviewers, to conduct the Site 
Assessments.  Tenant shall supply to the Site Reviewers such historical 
and operational information regarding the Leased Premises as may be 
reasonably requested by the Site Reviewers to facilitate the Site 
Assessments, and shall make available for meetings with the Site 
Reviewers appropriate personnel having knowledge of such matters.  
Landlord shall pay the cost of any such Site Assessment unless an 
Environmental Violation is found, in which event the cost shall be paid 
by Tenant.

        (d)     If an Environmental Violation occurs or is found to exist 
and, in Landlord's reasonable judgment, the cost of remediation of, or 
other response action with respect to, the same is likely to exceed 
$250,000, or, if an Event of Default under Paragraph 22(a)(i) hereof has 
occurred during the immediately preceding twelve (12) month period, 
$50,000, Tenant shall provide to Landlord and Lender within ten (10) days 
after Landlord's or Lender's request therefor, adequate financial 
assurances that Tenant will effect such remediation or other response 
action in accordance with applicable Environmental Laws.

        (e)     Notwithstanding any other provision of this Lease, if an 
Environmental Violation occurs or is found to exist that would render the 
Leased Premises untenantable or unmarketable and the Term would otherwise 
terminate or expire, then, at the option of Landlord, the Term shall be 
automatically extended beyond the date of termination or expiration and 
this Lease shall remain in full force and effect beyond such date until 
the earlier to occur of (i) the completion of all remedial or other 
response action in accordance with applicable Environmental Laws or 
(ii) the date specified in a written notice from Landlord to Tenant 
terminating this Lease.

        (f)     If Tenant fails to comply with (or promptly commence to 
comply with and diligently pursue to completion) any requirement of any 
Environmental Law in connection with any Environmental Violation which 
occurs or is found to exist, then after ten (10) days prior notice to 
Tenant (except that no notice shall be required if any emergency exists) 
Landlord and/or Lender shall have the right (but no obligation) to take 
any and all actions as Landlord and/or Lender shall deem necessary or 
advisable in order to cure such Environmental Violation.

        (g)     Tenant shall notify Landlord and Lender immediately after 
becoming aware of any Environmental Violation (or alleged Environmental 
Violation) or noncompliance with any of the covenants contained in this 
Paragraph 10 and shall forward to Landlord and Lender immediately upon 
receipt thereof copies of all orders, claims, reports, notices, permits, 
applications or other communications relating to any such violation or 
noncompliance.

        (h)     All future leases, subleases or concession agreements 
relating to the Leased Premises entered into by Tenant shall contain 
covenants of the other party thereto which are comparable to the 
covenants contained in this Paragraph 10.

        (i)     Tenant shall not release The Perkin-Elmer Corporation ("PE") 
from any of its obligations under the Asset Purchase Agreement, dated 
March 16, 1990, between Tenant and PE that relate to clause (f) of 
Section 6.2 thereof or otherwise amend said clause (f) or any other 
applicable provision without having obtained the prior written approval 
of Landlord and Lender.  Tenant represents and warrants to Landlord that 
the indemnity under clause (f) of Section 6.2 includes 1, 
1-dichloroethene on the Leased Premises.

        11.     Liens; Recording.

        (a)     Tenant shall not, directly or indirectly, create or permit to 
be created or to remain and shall promptly discharge or remove any lien, 
levy or encumbrance on any of the Leased Premises or on any Rent or any 
other sums payable by Tenant under this Lease, other than any Mortgage or 
Assignment, the Permitted Encumbrances and any mortgage, lien, 
encumbrance or other charge created by or resulting solely from any act 
or omission of Landlord.  NOTICE IS HEREBY GIVEN THAT LANDLORD SHALL NOT 
BE LIABLE FOR ANY LABOR, SERVICES OR MATERIALS FURNISHED OR TO BE 
FURNISHED TO TENANT OR TO ANYONE HOLDING OR OCCUPYING ANY OF THE LEASED 
PREMISES THROUGH OR UNDER TENANT, AND THAT NO MECHANICS' OR OTHER LIENS 
FOR ANY SUCH LABOR, SERVICES OR MATERIALS SHALL ATTACH TO OR AFFECT THE 
INTEREST OF LANDLORD IN AND TO ANY OF THE LEASED PREMISES.  LANDLORD 
May AT ANY TIME, AND AT LANDLORD'S REQUEST TENANT SHALL PROMPTLY, POST 
ANY NOTICES ON THE LEASED PREMISES REGARDING SUCH NON-LIABILITY OF 
LANDLORD.

        (b)     Tenant shall execute, deliver and record, file or register 
(collectively, "record") all such instruments as may be required or 
permitted by any present or future Law in order to evidence the 
respective interests of Landlord and Tenant in the Leased Premises, and 
shall cause a memorandum of this Lease (or, if such a memorandum cannot 
be recorded, this Lease), and any supplement hereto or thereto, to be 
recorded in such manner and in such places as may be required or 
permitted by any present or future Law in order to protect the validity 
and priority of this Lease.

        12.     Maintenance and Repair.

        (a)     Tenant shall at all times maintain, at Tenant's sole cost and 
expense, the Existing Premises and the Adjoining Property in 
substantially as good repair and appearance as they are in on the date 
hereof and shall at all times maintain the Project I Improvements and 
Project II Improvements in substantially as good repair and appearance as 
they are on the Project I Final Completion Date and Project II Final 
Completion Date, ordinary wear and tear excepted, and fit to be used for 
their intended use in accordance with the practices generally recognized 
as then acceptable by other companies in its industry, and, in the case 
of the Equipment, in as good mechanical condition as it was on the later 
of the date hereof or the date of its installation, except for ordinary 
wear and tear.  Tenant shall take every other reasonable action necessary 
or appropriate for the preservation and safety of the Leased Premises.  
Tenant shall promptly make all Alterations of every kind and nature, 
whether foreseen or unforeseen, which may be required to comply with the 
foregoing requirements of this Paragraph 12(a).  Landlord shall not be 
required to make any Alteration, whether foreseen or unforeseen, or to 
maintain any of the Leased Premises or Adjoining Property in any way, and 
Tenant hereby expressly waives any right which may be provided for in any 
Law now or hereafter in effect to make Alterations at the expense of 
Landlord or to require Landlord to make Alterations.  Any Alteration made 
by Tenant pursuant to this Paragraph 12 shall be made in conformity with 
the provisions of Paragraph 13.

        (b)     If any Improvement, now or hereafter constructed, shall 
(i) encroach upon any setback or any property, street or right-of-way 
adjoining the Leased Premises, (ii) violate the provisions of any 
restrictive covenant affecting the Leased Premises, (iii) hinder or 
obstruct any easement or right-of-way to which any of the Leased Premises 
is subject or (iv) impair the rights of others in, to or under any of the 
foregoing, Tenant shall, at Tenant's sole cost and expense, promptly 
after receiving a notice thereof, correct such condition from the party 
entitled to make such demand, and either (A) obtain from all necessary 
parties waivers or settlements of all claims, liabilities and damages 
resulting from each such encroachment, violation, hindrance, obstruction 
or impairment, whether the same shall affect Landlord, Tenant or both, or 
(B) take such action as shall be necessary to remove all such 
encroachments, hindrances or obstructions and to end all such violations 
or impairments, including, if necessary, making Alterations.

        13.     Alterations and Improvements.

        (a)     Tenant shall have the right, without having obtained the 
prior written consent of Landlord and Lender, to make (i) non-structural 
Alterations to the Leased Premises, (ii) structural Alterations or a 
series of related structural Alterations that, as to any such Alterations 
or series of related Alterations, do not cost in excess of $1,000,000 or, 
with respect to Alterations to any "clean room" test area in Buildings 2, 
3 or 4 and any "process laboratory" in Buildings 2, 3 and 4, $2,500,000, 
(iii) to install Equipment in the Improvements or accessions to the 
Equipment that, as to such Equipment or accessions, do not cost in excess 
of $1,000,000 or, with respect to Alterations to any "clean room" test 
area in Buildings 2, 3 and 4 and any "process laboratory" in Buildings 2, 
3 and 4 $2,500,000, and (iv) the Alterations identified in Schedule 2 
attached hereto, so long as at the time of construction or installation 
of any such Equipment or Alterations pursuant to clauses (i) through (iv) 
no Event of Default exists and the value and utility of the Leased 
Premises is not diminished thereby and no such Alterations shall be 
permitted under this Paragraph 13 with respect to the Project II 
Improvements until the Project II Final Completion Date.  If the cost of 
any structural Alterations, series of related structural Alterations, 
Equipment or accessions thereto is in excess of $1,000,000 or, with 
respect to Alterations to any "clean room" test area in Buildings 2, 3 or 
4 and any "process laboratory" in Buildings 2, 3 or 4, $2,500,000, the 
prior written approval of Lender shall be required, such approval not to 
be unreasonably withheld, delayed or conditioned, but may be withheld if 
an Event of Default exists and remains uncured.  Tenant shall not 
construct upon the Land any additional buildings without having first 
obtained the prior written consent of Landlord and Lender.

        (b)     If Tenant makes any Alterations pursuant to this Paragraph 13 
or Paragraph 36 or as required by Paragraph 12 or 17 (such Alterations 
and actions being hereinafter collectively  referred to as "Work"), 
whether or not Landlord's or Lender's consent is required, then (i) the 
market value of the Leased Premises shall not be lessened by any such 
Work or its usefulness impaired, (ii) all such Work shall be performed by 
Tenant in a good and workmanlike manner, (iii) all such Work shall be 
expeditiously completed in compliance with all Legal Requirements, 
(iv) all such Work shall comply with the Insurance Requirements, (v) if 
any such Work involves the replacement of Equipment or parts thereto, all 
replacement Equipment or parts shall have a value and useful life so as 
not to diminish the value of the Improvements, (vi) Tenant shall promptly 
discharge or remove all liens filed against any of the Leased Premises 
arising out of such Work, (vii) Tenant shall procure and pay for all 
permits and licenses required in connection with any such Work, 
(viii) all such Work that constitutes part of the Leased Premises shall 
be the property of Landlord and shall be subject to this Lease, and 
Tenant shall execute and deliver to Landlord any document requested by 
Landlord evidencing the assignment to Landlord of all estate, right, 
title and interest (other than the leasehold estate created hereby) of 
Tenant or any other Person thereto or therein, and (ix) Tenant shall 
comply, to the extent requested by Landlord or required by this Lease, 
with the provisions of Paragraph 19(a), whether or not such Work involves 
restoration of the Leased Premises.

        14.     Permitted Contests.  Notwithstanding any other provision of 
this Lease, Tenant shall not be required to (a) pay any Imposition, 
(b) comply with any Legal Requirement, (c) discharge or remove any lien 
referred to in Paragraph 11 or 13 or (d) take any action with respect to 
any encroachment, violation, hindrance, obstruction or impairment 
referred to in Paragraph 12(b) (such non-compliance with the terms hereof 
being hereinafter referred to collectively as "Permitted Violations"), so 
long as at the time of such contest no Event of Default exists and so 
long as Tenant shall contest, in good faith, the existence, amount or 
validity thereof, the amount of the damages caused thereby, or the extent 
of its or Landlord's liability therefor by appropriate proceedings which 
shall operate during the pendency thereof to prevent or stay (i) the 
collection of, or other realization upon, the Permitted Violation so 
contested, (ii) the sale, forfeiture or loss of any of the Leased 
Premises or any Rent to satisfy or to pay any damages caused by any 
Permitted Violation, (iii) any material interference with the use or 
occupancy of any of the Leased Premises, (iv) any interference with the 
payment of any Rent, (v) the cancellation or increase in the rate of any 
insurance policy or a statement by the carrier that coverage will be 
denied or (vi) the enforcement or execution of any injunction, order or 
Legal Requirement with respect to the Permitted Violation.  Tenant shall 
provide Landlord security which is satisfactory, in Landlord's reasonable 
judgment, to assure that such Permitted Violation is corrected, including 
all Costs, interest and penalties that may be incurred or become due in 
connection therewith.  While any proceedings which comply with the 
requirements of this Paragraph 14 are pending and the required security 
(if any) is held by Landlord, Landlord shall not have the  right to 
correct any Permitted Violation thereby being contested unless Landlord 
is required by Law to correct such Permitted Violation and Tenant's 
contest does not prevent or stay such requirement as to Landlord.  Each 
such contest shall be promptly and diligently prosecuted by Tenant to a 
final conclusion, except that Tenant, so long as the conditions of this 
Paragraph 14 are at all times complied with, has the right to attempt to 
settle or compromise such contest through negotiations.  Tenant shall pay 
any and all losses, judgments, decrees and Costs in connection with any 
such contest and shall, promptly after the final determination of such 
contest, fully pay and discharge the amounts which shall be levied, 
assessed, charged or imposed or be determined to be payable therein or in 
connection therewith, together with all penalties, fines, interest and 
Costs thereof or in connection therewith, and perform all acts the 
performance of which shall be ordered or decreed as a result thereof.  No 
such contest shall subject Landlord or Lender to the risk of any civil or 
criminal liability.

        15.     Indemnification. 

        (a)     Tenant shall pay, protect, indemnify, save and hold harmless 
Landlord, Lender, its officers, directors, shareholders, employees and 
trustees and all other Persons described in Paragraph 30 (each an 
"Indemnitee") from and against any and all liabilities, obligations, 
fines, losses, damages (including punitive damages), penalties, Costs, 
causes of action, suits, claims, demands or judgments of any nature 
whatsoever, howsoever caused, without regard to the form of action and 
whether based on strict liability, gross negligence, negligence or any 
other theory of recovery at law or in equity, arising from (i) any matter 
pertaining to the acquisition (or the negotiations leading thereto), 
ownership, use, non-use, occupancy, operation, condition, design, 
construction, maintenance, repair or restoration of the Leased Premises 
or Adjoining Property, (ii) any casualty in any manner arising from the 
Leased Premises or Adjoining Property, whether or not Landlord has or 
should have knowledge or notice of any defect or condition causing or 
contributing to said casualty, (iii) any violation by Tenant of any 
provision of this Lease, any contract or agreement to which Tenant is a 
party, any Legal Requirement or any Permitted Encumbrance or (iv) any 
alleged, threatened or actual Environmental Violation, however 
immaterial, including (A) liability for response costs and for costs of 
removal and remedial action incurred by the United States Government, any 
state or local governmental unit or any other Person, or damages from 
injury to or destruction or loss of natural resources, including the 
reasonable costs of assessing such injury, destruction or loss, incurred 
pursuant to Section 107 of CERCLA, or any successor section or act or 
provision of any similar state or local Law, (B) liability for costs and 
expenses of abatement, correction or clean-up, fines, damages, response 
costs or penalties which arise from the provisions of any of the other 
Environmental Laws and (C) liability for personal injury or property 
damage arising under any statutory or common-law tort  theory, including 
damages assessed for the maintenance of a public or private nuisance or 
for carrying on of a dangerous activity, but excluding in all cases any 
and all liabilities, losses, damages (including punitive damages), 
penalties, costs, causes of action, suits, claims, demands or judgments 
caused by the gross negligence or willful misconduct of any Indemnitee.

        (b)     In case any action or proceeding is brought against any 
Indemnitee by reason of any such claim, such Indemnitee may either (i) 
retain its own counsel and defend such action (it being understood that 
Tenant may employ counsel of its choice to monitor the defense of any 
such action) or (ii) notify Tenant to resist or defend such action or 
proceeding by retaining counsel reasonably satisfactory to such 
Indemnitee, and such Indemnitee will cooperate and assist in the defense 
of such action or proceeding if reasonably requested so to do by Tenant.

        (c)     The obligations of Tenant under this Paragraph 15 shall 
survive any termination or expiration of this Lease.

        16.     Insurance.

        (a)     Tenant shall maintain the following insurance on or in 
connection with the Leased Premises:

                (i)  Insurance against physical loss or damage to the
Improvements and Equipment as provided under a standard "All Risk" property
policy including but not limited to flood (if the Leased Premises is in a
flood zone) in amounts not less than the actual replacement cost of the
Improvements and Equipment.  Such policies shall contain replacement cost
and agreed amount endorsements and shall contain deductibles not more than
$50,000.00 per occurrence.  Tenant shall maintain earthquake insurance for
the Improvements and Equipment in an amount equal to the product of full
replacement cost of the Improvements multiplied by the Probable Maximum Loss
of the Improvements determined every four (4) years by a seismic engineer
mutually acceptable to Landlord and Tenant with a deductible of not more
than 25% of the product of the full replacement cost of the Improvements
multiplied by the Probable Maximum Loss, provided, however, that in the
event of a substantial change in the availability or cost of earthquake
coverage Landlord and Tenant shall in good faith negotiate a different
amount or a different deductible or other different terms of such insurance
(subject to the consent of Lender), taking into account the cost and
availability of such insurance and the objective of reasonably protecting
the interests of Landlord and Lender.

                (ii)  Commercial General Liability Insurance against claims
for personal and bodily injury, death or property damage occurring on, in or
as a result of the use of the Leased Premises, in an amount not less than
$15,000,000 per occurrence/annual aggregate including but not limited to
Incidental Medical Malpractice, Garagekeepers Liability, Host Liquor
Liability, Non-Owned and Hired Automobile Liability and all other coverage
extensions that are usual and customary for properties of this size and type
provided, however, that the Landlord shall have the right to require such
higher limits as may be reasonable and customary for properties of this size
and type.

                (iii)  Workers' Compensation Insurance covering all persons
employed by Tenant in connection with any work done on or about any of the
Leased Premises for which claims for death, disease or bodily injury may be
asserted against Landlord, Tenant or any of the Leased Premises or, in lieu
of such Workers' Compensation Insurance, a program of self-insurance
complying with the rules, regulations and requirements of the appropriate
agency of the State.

                (iv)  Comprehensive Boiler and Machinery Insurance on any of
the Equipment or any other equipment on or in the Leased Premises including
but not limited to Service Interruption, Expediting Expenses, Ammonia
Contamination, Hazardous Clean-Up and Comprehensive Object Definition, in an
amount not less than $1,000,000 for damage to property, bodily injury or
death resulting from such covered perils as found in a standard

deductible not in excess of $50,000.

                (v)  Business Income/Interruption Insurance to include Loss
of Rents on an Actual Loss Sustained basis with a period of indemnity not
less than one year from the time of loss.  Such insurance shall name
Landlord and Lender as "loss payee" solely with respect to Rent payable to
or for the benefit of Landlord under this Lease.

                (vi)  During construction of the Project I Improvements and
the Project II Improvements and during any period in which substantial
Alterations at the Leased Premises are being undertaken, Builder's Risk
insurance covering the total completed value including any "soft costs" with
respect to the Improvements being altered or repaired (on a completed value,
non-reporting basis), replacement cost of work performed and equipment,
supplies and materials furnished in connection with such construction or
repair of Improvements or Equipment, together with such "soft cost"
endorsements and such other endorsements as Landlord may reasonably require

any insurance required pursuant to this Paragraph 16, including without
limitation amounts of coverage, deductibles, form of mortgagee clause) on or
in connection with any of the Leased Premises as Landlord or Lender may
reasonably require, which at the time is usual and commonly obtained in
connection with properties similar in type of building size and use to the
Leased Premises.


        (b)     The insurance required by Paragraph 16(a) shall be written by 
companies which have a Best's rating of A:X or above and are admitted in, 
and approved to write insurance policies by the State Insurance 
Department for, the State.  The insurance policies (i) shall be for such 
terms as Landlord may reasonably approve, (ii) shall be in amounts 
sufficient at all times to satisfy any coinsurance requirements thereof 
and (iii) shall (except for the worker's compensation insurance referred 
to in Paragraph 16(a)(iii) hereof) name Landlord, Tenant and Lender as 
additional insureds or loss payees, as their respective interests may 
appear.  If said insurance or any part thereof shall expire, be 
withdrawn, become void, voidable, unreliable or unsafe for any reason, 
including a breach of any condition thereof by Tenant or the failure or 
impairment of the capital of any insurer, or if for any other reason 
whatsoever said insurance shall become  reasonably unsatisfactory to 
Landlord of Lender, Tenant shall immediately obtain new or additional 
insurance reasonably satisfactory to Landlord and Lender.

        (c)     Each policy required by any provision of Paragraph 16(a), 
except clause (iii) thereof, shall provide that it may not be canceled, 
substantially modified or allowed to lapse on any renewal date except 
after sixty (60) days' prior notice to Landlord and Lender.  Each such 
policy shall also provide that any loss otherwise payable thereunder 
shall be payable notwithstanding (i) any act or omission of Landlord or 
Tenant which might, absent such provision, result in a forfeiture of all 
or a part of such insurance payment, (ii) the occupation or use of any of 
the Leased Premises for purposes more hazardous than those permitted by 
the provisions of such policy, (iii) any foreclosure or other action or 
proceeding taken by Lender pursuant to any provision of the Mortgage, 
Note, Assignment or other document evidencing or securing the Loan upon 
the happening of an event of default therein or (iv) any change in title 
to or ownership of any of the Leased Premises.

        (d)     Tenant shall pay as they become due all premiums for the 
insurance required by Paragraph 16(a), shall renew or replace each policy 
and deliver to Landlord evidence of the payment of the full premium 
therefor or installment then due prior to the expiration date of such 
policy, and shall promptly deliver to Landlord each original policy or a 
duplicate thereof.

        (e)     Anything in this Paragraph 16 to the contrary 
notwithstanding, any insurance which Tenant is required to obtain 
pursuant to Paragraph 16(a) may be carried under a "blanket" or umbrella 
policy or policies covering other properties or liabilities of Tenant, 
provided that such "blanket" or umbrella policy or policies otherwise 
comply with the provisions of this Paragraph 16 and provided further that 
such policies shall provide for a reserved amount thereunder with respect 
to the Leased Premises sufficient to assure that the amount of insurance 
required by this Paragraph 16 will be available notwithstanding any 
losses with respect to other property covered by such blanket policies.  
The amount of the total insurance allocated to the Leased Premises, which 
amount shall be not less than the amounts required pursuant to this 
Paragraph 16, shall be specified either (i) in each such "blanket" or 
umbrella policy or (ii) in a written statement, which Tenant shall 
deliver to Landlord and Lender, from the insurer thereunder.  The 
original or a certified copy of each such "blanket" or umbrella policy 
shall promptly be delivered to Landlord and Lender.

        (f)     Tenant shall promptly comply with and conform to (i) all 
provisions of each insurance policy required by this Paragraph 16 and 
(ii) all requirements of the insurers thereunder applicable to Landlord, 
Tenant or any of the Leased Premises or to the use, manner of use, 
occupancy, possession, operation, maintenance, alteration or repair of 
any of the Leased Premises, even if such compliance necessitates 
Alterations or results in  interference with the use or enjoyment of any 
of the Leased Premises.

        (g)     Tenant shall not carry separate insurance concurrent in form 
or contributing in the event of a Casualty with that required in this 
Paragraph 16 unless (i) Landlord and Lender are included therein as loss 
payee or additional insureds, with loss payable as provided herein, and 
(ii) such separate insurance complies with the other provisions of this 
Paragraph 16.  Tenant shall immediately notify Landlord and Lender of 
such separate insurance and shall deliver to Landlord and Lender copies 
of the policies therefor.

        (h)     All policies shall contain effective waivers by the carrier 
against all claims for insurance premiums against Landlord and Lender and 
shall contain full waivers of subrogation against the Landlord and 
Lender.

        (i)     All proceeds of any insurance required under Paragraph 16(a) 
shall be payable as follows:

                (i)  Except for proceeds payable to a Person other than
Landlord, Tenant or Lender and, so long as no Event of Default exists and
remains uncured, proceeds of less than $1,000,000, all proceeds of insurance
required under clauses (ii), (iv) and (vii) of Paragraph 16(a) and proceeds
attributable to the general liability coverage provisions of Builder's Risk
insurance under clause (vi) of Paragraph 16(a) shall be payable to Landlord
or, if required by the Mortgage or requested by Lender pursuant to the
Mortgage, to Lender.  All proceeds of insurance required under clause (v) of
Paragraph 16(a) shall be payable to Landlord or, if required by the
Mortgage, to Lender.

                (ii)  Proceeds of insurance required under clause (i) of
Paragraph 16(a) and proceeds attributable to Builder's Risk insurance (other
than its general liability coverage provisions) under clause (vi) of
Paragraph 16(a) shall be payable as follows:


                        (A)  In the event of a Casualty that is a
Termination Event for which a Termination Notice has been given under
Paragraph 18(a), the proceeds shall be payable to Landlord or, if required
by the Mortgage or requested by Lender pursuant to the Mortgage, to Lender. 
Landlord shall retain or apply the Net Award in accordance with the
provisions of Paragraphs 18 and 20.

                        (B)  In the event of a Casualty that is not a
Termination Event where the proceeds exceed $1,000,000, the proceeds shall
be payable to Landlord or, if required by the Mortgage or requested by
Lender pursuant to the Mortgage, to Lender.  Landlord shall apply the Net
Award in accordance with the provisions of Paragraph 19.

                        (C)  In the event of a Casualty that is not a
Termination Event where the proceeds are equal to or less than $1,000,000
and provided no Event of Default exists and is continuing, and no fact or
condition exists which with the lapse of time or giving of notice, or both,
would in Landlord's or Lender's judgment constitute an Event of Default, at
the time such proceeds are paid, the Net Award shall be payable to Tenant. 
Tenant shall apply the Net Award to restoration of the Leased Premises in
accordance with the applicable provisions of this Lease.  If an Event of
Default exists and is continuing or a fact or condition exists which with
the lapse of time or giving of notice, or both, would in Landlord's or
Lender's judgment constitute an Event of Default, all proceeds shall be
payable to Landlord or Lender.

                (iii)  In the event that Tenant is listed as a payee on a
check from an insurance carrier for insurance proceeds which subparagraphs
(i) and (ii) provide are to be payable to Landlord, Lender or another party
or parties, Tenant shall cooperate by promptly endorsing said check over to
the party to whom the proceeds are to be payable under subparagraphs (i) or
(ii).  Tenant hereby appoints each of Landlord or Lender as Tenant's
attorneys-in-fact to endorse any such check.

        17.     Casualty and Condemnation.

        (a)     If any Casualty occurs the insurance proceeds for which is 
reasonably estimated by Tenant to be equal to or in excess of One Hundred 
Thousand Dollars ($100,000), Tenant shall give Landlord and Lender 
immediate notice thereof.  So long as no Event of Default exists, and 
subject to the provisions of Paragraph 16(i)(ii), Tenant is hereby 
authorized to adjust, collect and compromise all claims under any of the 
insurance policies required by Paragraph 16(a) (except public liability 
insurance claims payable to a Person other than Tenant, Landlord or 
Lender) and to execute and deliver on behalf of Landlord and Lender all 
necessary proofs of loss, receipts, vouchers and releases required by the 
insurers and Landlord and Lender shall have the right to join with Tenant 
therein.  Any adjustment, settlement or compromise of any such claim in 
excess of $1,000,000 shall be subject to the prior written approval of 
Landlord and Lender, which shall not be unreasonably withheld, 
conditioned or delayed and Landlord and Lender shall have the right to 
prosecute or contest, or to require Tenant to prosecute or contest, any 
such claim, adjustment, settlement or compromise.  If an Event of Default 
exists, Tenant shall not be entitled to adjust, collect or compromise any 
claim or to participate with Landlord or Lender in any adjustment, 
collection and compromise of the Net Award payable in connection with a 
Casualty.  Tenant agrees to sign, upon the request of Landlord or Lender, 
all proofs of loss, receipts, vouchers and releases.  Each insurer is 
hereby authorized and directed to make payment under said policies in 
excess of $1,000,000 and return of unearned premiums, directly to 
Landlord or, if required by the Mortgage or requested by Lender pursuant 
to the Mortgage, to Lender instead of to Landlord or Landlord and Tenant 
jointly, and Tenant hereby appoints each of Landlord and Lender as 
Tenant's attorneys-in-fact to endorse any draft therefor.

        (b)     Tenant, immediately upon receiving a Condemnation Notice, 
shall notify Landlord and Lender thereof.  So long as no Event of Default 
exists, Tenant is authorized to collect, settle and compromise the amount 
of any Net Award and Landlord and Lender shall have the right to join 
with Tenant therein.  No agreement with any condemnor in settlement or 
under threat of any Condemnation shall be made by Tenant without the 
written consent of Landlord and Lender which shall not be unreasonably 
withheld, conditioned or delayed.  If an Event of Default exists, 
Landlord and Lender shall be authorized to collect, settle and compromise 
the amount of any Net Award and Tenant shall not be entitled to 
participate with Landlord and Lender in any Condemnation proceeding or 
negotiations under threat thereof or to contest the Condemnation or the 
amount of the Net Award therefor.  Subject to the provisions of this 
Paragraph 17(b), Tenant hereby irrevocably assigns to Landlord and Lender 
any award or payment to which Tenant is or may be entitled by reason of 
any Condemnation, whether the same shall be paid or payable for Tenant's 
leasehold interest hereunder or otherwise; but nothing in this Lease 
shall impair Tenant's right to any award or payment on account of 
Tenant's trade fixtures, equipment or other tangible property which is 
not part of the Equipment, moving expenses or loss of business, if 
available, to the extent that and so long as (i) Tenant shall have the 
right to make, and does make, a separate claim therefor against the 
condemnor and (ii) such claim does not in any way reduce either the 
amount of the award otherwise payable to Landlord for the Condemnation of 
Landlord's fee interest in the Leased Premises or the amount of the award 
(if any) otherwise payable for the Condemnation of Tenant's leasehold 
interest hereunder.

        (c)     If any Partial Casualty (whether or not insured against) or 
Partial Condemnation shall occur, this Lease shall continue, 
notwithstanding such event, and there shall be no abatement or reduction 
of any Monetary Obligations, except as provided in Paragraph 17(d) and 
19(c).  Promptly after such Partial Casualty or Partial Condemnation, 
Tenant, as required in Paragraph 12(a), shall commence and diligently 
continue to restore the Leased Premises as nearly as practicable to their 
value, condition and character immediately prior to such event.  Upon the 
receipt by Landlord of the entire Net Award of such Partial Casualty or 
Partial Condemnation, Landlord shall make such Net Award available to 
Tenant for restoration in accordance with and subject to the provisions 
of Paragraph 19(a).  If any Casualty or Condemnation which is not a 
Partial Casualty or Partial Condemnation shall occur, Tenant shall comply 
with the terms and conditions of Paragraph 18.

        (d)     In the event of a Requisition of any of the Leased Premises, 
if any Net Award payable by reason of such Requisition is retained by 
Landlord or Lender, each installment of Basic Rent payable on or after 
the date on which the Net Award is paid to Landlord shall be reduced by a 
fraction, the denominator of which shall be the total amount of all Basic 
Rent due from such date to and including the last day of the Term 
(calculated on the basis of the Basic Rent in effect as of the date of 
the Requisition) and the numerator of which shall be the amount of such 
Net Award retained by Landlord.  Upon the expiration of the Term, any 
portion of such Net Award which shall not have been previously credited 
to Tenant shall be retained by Landlord.

        18.     Termination Events.

        (a)     If (i) the Leased Premises shall be taken by a Taking or (ii) 
any substantial portion of the Leased Premises shall be taken by a Taking 
or all or any substantial portion of  the Leased Premises shall be 
damaged or destroyed by a Casualty and, in such case, Tenant certifies to 
Landlord that it will forever abandon operations at the Leased Premises 
(each of the events described in the above clauses (i) and (ii) shall 
hereinafter be referred to as a "Termination Event"), then (x) in the 
case of (i) above, Tenant shall be obligated, within thirty (30) days 
after Tenant receives a Condemnation Notice and (y) in the case of (ii) 
above, Tenant shall have the option, within thirty (30) days after Tenant 
receives a Condemnation Notice or thirty (30) days after the Casualty, as 
the case may be, to give to Landlord and Lender written notice of the 
Tenant's option to terminate this Lease (a "Termination Notice") in the 
form described in Paragraph 18(b).

        (b)     A Termination Notice shall contain (i) notice of Tenant's 
intention to terminate this Lease on the first Basic Rent Payment Date 
which occurs at least ninety (90) days after the Fair Market Value Date 
(the "Termination Date"), (ii) a binding and irrevocable offer of Tenant 
to purchase the Leased Premises for an amount equal to the Termination 
Amount and (iii) if the Termination Event is an event described in 
Paragraph 18(a)(ii), the certification described therein and a certified 
resolution of the Board of Directors of Tenant authorizing the same.  
Promptly upon the delivery to Landlord of a Termination Notice, Landlord 
and Tenant shall commence to determine the Fair Market Value of the 
Leased Premises. 

        (c)     If Landlord shall reject such offer to purchase the Leased 
Premises by written notice to Tenant (a "Rejection"), which Rejection 
shall contain the written consent of Lender, not later than thirty (30) 
days following the Fair Market Value Date, then this Lease shall 
terminate on the Termination Date; provided that, if Tenant has not 
satisfied all Monetary Obligations and all other obligations and 
liabilities under this Lease which have arisen on or prior to the 
Termination Date (collectively, "Remaining Obligations") on the 
Termination Date, then Landlord may, at its option, extend the date on 
which this Lease may terminate to a date which is no later than the first 
Basic Rent Payment Date after the Termination Date on which Tenant has 
satisfied all Remaining Obligations.  Upon such termination (i) all 
obligations of Tenant hereunder shall terminate except for any Surviving 
Obligations, (ii) Tenant shall promptly vacate and shall have no further 
right, title or interest in or to any of the Leased Premises and 
(iii) the Net Award shall be retained by Landlord.  Notwithstanding 
anything to the contrary hereinabove contained, if Tenant shall have 
received a Rejection and, on the date when this Lease would otherwise 
terminate as provided above, Landlord shall not have received the full 
amount of the Net Award payable by reason of the applicable Termination 
Event, then on the Termination Date Tenant shall assign to Landlord all 
of its right, title and interest, if any, in and to the Net Award.

        (d)     Unless Tenant shall have received a Rejection not later than 
the thirtieth (30th) day following the Fair Market Value Date, Landlord 
shall be conclusively presumed to have accepted such offer.  If such 
offer is accepted by Landlord then, on the Termination Date, Tenant shall 
pay to Landlord (or Lender if the Mortgage requires or permits Lender to 
so require) the Termination Amount and all Remaining Obligations and, if 
requested by Tenant, Landlord shall (i) convey to Tenant the Leased 
Premises or the remaining portion thereof, if any, and (ii) pay to or 
assign to Tenant its entire interest in and to the Net Award, all in 
accordance with Paragraph 20. 

        19.     Restoration; Reduction of Rent.

        (a)     So long as no Event of Default, or fact or condition which 
with the lapse of time or giving of notice or both would, in the judgment 
of Landlord or Lender, constitute an Event of Default, exists, any Net 
Award up to and including $1,000,000 shall be paid directly to Tenant and 
Tenant shall restore the Leased Premises in accordance with the 
requirements of Paragraph 13(b) of this Lease.  Any Net Award in excess 
of $1,000,000 shall be made available by Landlord to Tenant for the 
restoration of any of the Leased Premises, and Landlord (or Lender if 
required by any Mortgage or if the Mortgage permits Lender to so require) 
shall hold such Net Award in a fund (the "Restoration Fund") and disburse 
amounts from the Restoration Fund only in accordance with the following 
conditions:

                (i)  prior to commencement of restoration, (A) the
architects, contracts, contractors, plans and specifications for the
restoration shall have been approved by Landlord and Lender, such approval
not to be unreasonably withheld, conditioned or delayed and (B) Landlord and
Lender shall, upon reasonable request and based upon a review of the
contractor's and prime subcontractors' credit, be provided with acceptable
performance bonds which insure satisfactory completion of the restoration,
are in an amount and form and have a surety acceptable to Landlord, and name
Landlord and Lender as additional dual obligees;

                (ii)  at the time of any disbursement, no Event of Default,
or fact or condition which with the giving of notice or lapse of time or
both would, in the judgment of Landlord or Lender, constitute an Event of
Default shall exist and any mechanics' or materialmen's liens filed against
any of the Leased Premises shall have been insured over or covered by a bond;

                (iii)  disbursements shall be made from time to time in an
amount not exceeding the cost of the work completed since the last
disbursement, upon receipt of (A) satisfactory evidence, including
architects' certificates, of the stage of completion, the estimated total
cost of completion and performance of the work to date in a good and
workmanlike manner in accordance with the contracts, plans and
specifications, (B) waivers of liens, (C) contractors' and subcontractors'
sworn statements as to completed work and the cost thereof for which payment
is requested, (D) a satisfactory bringdown of title insurance and (E) other
evidence of cost and payment so that Landlord and Lender can verify that the
amounts disbursed from time to time are represented by work that is
completed, in place and free and clear of mechanics' and materialmen's lien
claims;

                (iv)  each request for disbursement shall be accompanied by
a certificate of Tenant, signed by the president or a vice president or the
chief financial officer of Tenant, describing the work for which payment is
requested, stating the cost incurred in connection therewith, stating that
Tenant has not previously received payment for such work and, upon
completion of the work, also stating that the work has been fully completed
and complies with the applicable requirements of this Lease;

                (v)  Landlord or Lender may retain ten percent (10%) of the
Restoration Fund until the restoration is fully completed;

                (vi)  if the Restoration Fund is held by Lender it may be
commingled with Lender's other funds and shall bear interest unless
otherwise required by Lender; if it is held by Landlord it shall be
commingled with Landlord's other funds and shall bear interest at the best
available interest rate; and

                (vii)  such other reasonable conditions to insure timely,
lien free completion of the restoration as Landlord or Lender may impose.

        (b)     Prior to commencement of restoration and at any time during 
restoration, if the estimated cost of completing the restoration work 
free and clear of all liens, as determined by Landlord or if required by 
a Mortgage, by Lender, exceeds the amount of the Net Award available for 
such restoration, the amount of such excess shall, upon demand by 
Landlord, be paid by Tenant to Landlord or if required by a Mortgage or 
by Lender pursuant to the terms of a Mortgage, to Lender to be added to 
the Restoration Fund.  Any sum so added by Tenant which remains in the 
Restoration Fund upon completion of restoration shall be refunded to 
Tenant.  For purposes of determining the source of funds with respect to 
the disposition of funds remaining after the completion of restoration, 
the Net Award shall be deemed to be disbursed prior to any amount added 
by Tenant.

        (c)     If any sum remains in the Restoration Fund after completion 
of the restoration and any refund to Tenant pursuant to Paragraph 19(b), 
such sum (the "Remaining Sum") shall be retained by Landlord or, if 
required by a Note or Mortgage or by Lender pursuant to the terms of a 
Note or Mortgage, paid by Landlord to a Lender.  If the Remaining Sum is 
(i) retained by Landlord, each installment of Basic Rent payable on or 
after the Retention Date shall be reduced by a fraction, the denominator 
of which shall be the total amount of all Basic Rent due from such date 
to and including the last Basic Rent Payment Date for the then existing 
Term calculated on the basis of the Basic Rent then in effect and taking 
into account any applicable adjustments under Paragraphs 1(c)(i) and 
1(c)(ii) of Exhibit "D" and the numerator of which shall be the Remaining 
Sum, or (ii) paid to Lender, then each installment of Basic Rent 
thereafter payable shall be reduced in the same amount as payments are 
reduced under any Note as if the Loan were reamortized to reflect such 
payment, in each case until such Remaining Sum has been applied in full 
or until the Term has expired, whichever occurs first.  Landlord agrees 
that if the terms of a Note or Mortgage permit partial prepayment of the 
principal balance of the Loan without premium or penalty and, in such 
event, require the Lender to thereupon reamortize the Loan,  Landlord 
shall pay any Remaining Sum to Lender as a partial prepayment of the Loan 
and clause (ii) of this Paragraph  19(c) shall apply.  Upon the 
expiration of the Term, any portion of the Remaining Sum which has not 
been so applied shall be retained by Landlord.

        20.     Procedures Upon Purchase.

        (a)     If the Leased Premises is purchased by Tenant pursuant to any 
provision of this Lease, Landlord need not convey any better title 
thereto than that which was conveyed to Landlord, and Tenant shall accept 
such title, subject, however, to the Permitted Encumbrances and to all 
other liens, exceptions and restrictions on, against or relating to any 
of the Leased Premises and to all applicable Laws, but free of the lien 
of and security interest created by any Mortgage or Assignment and liens, 
exceptions and restrictions on, against or relating to the Leased 
Premises which have been created by or resulted solely from acts of 
Landlord after the date of this Lease, unless the same are Permitted 
Encumbrances or customary utility easements benefiting the Leased 
Premises or were created with the concurrence of Tenant or as a result of 
a default by Tenant under this Lease.

        (b)     Upon the date fixed for any such purchase of the Leased 
Premises pursuant to any provision of this Lease (any such date the 
"Purchase Date"), through an appropriate escrow, Tenant shall pay to 
Landlord, or to any Person to whom Landlord directs payment, the Relevant 
Amount therefor specified herein, in Federal Funds, less any credit of 
the Net Award received and retained by Landlord or Lender allowed against 
the Relevant Amount, and Landlord shall deliver to Tenant (i) a special 
warranty deed which describes the premises being conveyed and conveys the 
title thereto as provided in Paragraph 20(a), (ii) such other instruments 
as shall be necessary to transfer to Tenant or its designee any other 
property (or rights to any Net Award not yet received by Landlord or a 
Lender) then required to be sold by Landlord to Tenant pursuant to this 
Lease and (iii) any Net Award received by Landlord, not credited to 
Tenant against the Relevant Amount and required to be delivered by 
Landlord to Tenant pursuant to this Lease; provided, that if any Monetary 
Obligations remain outstanding on such date, then Landlord may deduct 
from the Net Award the amount of such Monetary Obligations; and further 
provided, that if any event has occurred which, in Landlord's reasonable 
judgment, is likely to subject any Indemnitee to any liability which 
Tenant is required to indemnify against pursuant to Paragraph 15, then an 
amount shall be deducted from the Net Award which, in Landlord's 
reasonable judgment, is sufficient to satisfy such liability, which 
amount shall be deposited in an escrow account with a financial 
institution reasonably satisfactory to Landlord and Tenant on terms 
reasonably satisfactory to Landlord and Tenant pending resolution of such 
matter.  If on the Purchase Date any Monetary Obligations remain 
outstanding and no Net Award is payable to Tenant by Landlord or the 
amount of such Net Award is less than the amount of the  Monetary 
Obligations, then Tenant shall pay to Landlord on the Purchase Date the 
amount of such Monetary Obligations.  Upon the completion of such 
purchase, this Lease and all obligations and liabilities of Tenant 
hereunder shall terminate, except any Surviving Obligations.

        (c)     If the Tenant shall cause completion of such purchase to be 
delayed after (i) the Termination Date, in the event of a purchase 
pursuant to Paragraph 18 or, (ii) the date scheduled for such purchase, 
in the event of a purchase under any other provision of this Lease then 
(x) Rent shall continue to be due and payable until completion of such 
purchase and (y) at Landlord's sole option, Fair Market Value shall be 
redetermined and the Relevant Amount payable by Tenant pursuant to the 
applicable provision of this Lease shall be adjusted to reflect such 
redetermination.  Landlord shall not be deemed to have caused completion 
of such purchase to be delayed if it in good faith disputes the process 
or methodology for determining Fair Market Value.

        (d)     Any prepaid Monetary Obligations paid to Landlord shall be 
prorated as of the Purchase Date, and the prorated unapplied balance 
shall be deducted from the Relevant Amount due to Landlord.

        21.     Assignment and Subletting; Prohibition against 
Leasehold Financing.

        (a)     Tenant shall have the right so long as no Event of Default 
has occurred and is continuing, upon thirty (30) days prior written 
notice to Landlord and Lender, with no consent of Landlord or Lender 
being required or necessary ("Preapproved Assignment") to assign this 
Lease to any Person ("Preapproved Assignee") that is a Subsidiary of 
Tenant on the date hereof or that, after the date hereof, is a 
wholly-owned Subsidiary of Tenant or which, whether or not in connection 
with the transfer or sale of all or substantially all of Tenant's 
business, immediately following such assignment satisfies all published 
criteria necessary to obtain a publicly traded unsecured senior debt 
rating of "A2" or better from Moody's Investors Services, Inc. or a 
rating of "A" or better from Standard & Poor's Ratings Service, and in 
the event all of such rating agencies cease to furnish such ratings, then 
a comparable rating by any rating agency reasonably acceptable to 
Landlord and Lender.

        (b)     During the Initial Term, if Tenant desires to assign this 
Lease to a Person ("Non-Preapproved Assignee") who would not be a 
Preapproved Assignee ("Non-Preapproved Assignment") then Tenant shall, 
not less than ninety (90) days prior to the date on which it desires to 
make a Non-Preapproved Assignment submit to Landlord and Lender 
information regarding the following with respect to the Non-Preapproved 
Assignee:  (A) credit, (B) capital structure, (C) management, 
(D) operating history, (E) proposed use of the Leased Premises and (F) 
risk factors associated with the proposed use of the Leased Premises by 
the Non-Preapproved Assignee, taking into account  factors such as 
environmental concerns, product liability and the like.  Landlord and 
Lender shall review such information and shall approve or disapprove the 
Non-Preapproved Assignee no later than the thirtieth (30th) day following 
receipt of all such information, and Landlord and Lender shall be deemed 
to have acted reasonably in granting or withholding consent for any or no 
reason if such grant or disapproval is based on any of the 
above-described information.  Notwithstanding anything to the contrary 
contained herein, if the request for consent to a Non-Preapproved 
Assignment is in connection with the sale by Tenant of all or 
substantially all of its assets, Landlord and Lender shall be deemed to 
have consented to the Non-Preapproved Assignment so long as no Event of 
Default has occurred and is continuing and if, immediately after the 
assignment, the Non-Preapproved Assignee has, on a pro forma basis, an 
Adjusted Consolidated Net Worth (as defined in Exhibit "E") of not less 
than the sum of (x) Fifty-three Million Dollars ($53,000,000) plus (y) an 
amount equal to 60% of Tenant's Consolidated Net Income on a cumulative 
basis for each fiscal quarter in which such Consolidated Net Income is 
positive, but with no adjustment for each fiscal quarter in which 
Consolidated Net Income is negative (calculated at the end of each fiscal 
quarter), commencing with the fiscal quarter of Tenant that commenced on 
August 1, 1996 and continuing for each quarter to and including the end 
of the fiscal quarter prior to the fiscal quarter in which the 
Non-Preapproved Assignment occurs.

        (c)     After the Initial Term, if Tenant desires to carry out a 
Non-Preapproved Assignment, then Tenant shall, not less than fifteen (15) 
days prior to the date on which it desires to make such Non-Preapproved 
Assignment, submit to Landlord (and Lender, if Lender's consent to the 
Non-Preapproved Assignment is required), reasonable information regarding 
the identity and credit of the Non-Preapproved Assignee.  Landlord (and 
Lender, if applicable) shall review such information and shall, no later 
than the fifteenth (15th) day following receipt of such information, 
approve or disapprove the Non-Preapproved Assignee.  Such approval shall 
be deemed given if the net worth of the Non-Preapproved Assignee is 
greater than or equal to the net worth of the Tenant as shown on its then 
most recently prepared financial statements, and otherwise such approval 
shall not be unreasonably withheld, conditioned or delayed.

        (d)     If Landlord and Lender withhold consent to the 
Non-Preapproved Assignment and Tenant desires to complete the 
Non-Preapproved Assignment, Tenant shall make a rejectable offer (the 
"Intended Assignment Offer") to purchase the Leased Premises for a 
purchase price equal to the Offer Amount and to consummate the purchase 
on the first Basic Rent Payment Date occurring thirty (30) days after the 
determination of Fair Market Value (the "Intended Assignment Purchase 
Date").  Notwithstanding the foregoing, if the Intended Assignment Offer 
is accepted by Landlord and the Non-Preapproved Assignment occurs on a 
date (the "Assignment Date") that is prior to the Intended Assignment 
Purchase Date, then on the Assignment Date Tenant shall deposit in escrow 
with Lender an amount (the "Deposit Amount") equal to one hundred percent 
(100%) of the sum of the Acquisition Cost and any estimated Prepayment 
Premium.  On the Intended Assignment Purchase Date, Tenant shall increase 
the Deposit Amount by the amount by which the actual Prepayment Premium 
exceeds the estimated Prepayment Premium.  The Deposit Amount shall be 
held by and invested by Lender and the Deposit Amount, together with any 
interest earned thereon, shall be applied on the Intended Assignment 
Purchase Date to payment of the Offer Amount.

        (e)     If Landlord shall reject the Intended Assignment Offer by 
notice to Tenant, such notice to contain the  written consent of Lender 
to such rejection, no later than the thirtieth (30th) day following 
receipt of the Intended Assignment Offer by Landlord, then this Lease 
shall remain in full force and effect and Landlord and Lender shall be 
deemed to have consented to the Non-Preapproved Assignment.  Nothing 
provided herein shall constitute a waiver by Landlord of the obligation 
of Tenant to comply with the requirements of this Paragraph 21(e) if a 
subsequent Non-Preapproved Assignment arises.  No rejection of the 
Intended Assignment Offer shall be effective for any purpose unless 
consented to in writing by Lender.

        (f)     Unless Landlord shall have rejected the Intended Assignment 
Offer by the foregoing notice to Tenant not later than the thirtieth 
(30th) day following receipt of information described in the foregoing 
Paragraph 21(b) or 21(c), Landlord shall be conclusively presumed to have 
accepted the Intended Assignment Offer.  If the Intended Assignment Offer 
is accepted by Landlord, Tenant shall pay to Landlord the Offer Amount 
(less the Deposit Amount and interest thereon paid to Landlord) on the 
Intended Assignment Purchase Date and, provided that no Rent or any other 
charge is due and unpaid under this Lease as of the Intended Assignment 
Purchase Date and Tenant is otherwise in compliance with the terms of 
this Lease, Landlord shall convey to Tenant the Leased Premises in 
accordance with the provisions of Paragraph 20 of this Lease.

        (g)     Any assignment of Tenant's interest in this Lease by 
operation of law as a result of any merger or consolidation by Tenant 
shall be governed by the provisions of Paragraph 1(c) of Exhibit "E".

        (h)     Tenant shall have the right, upon thirty (30) days prior 
written notice to Landlord and Lender, to enter into one or more 
subleases that demise, in the aggregate, up to but not in excess of 
thirty-one percent (31%) of the gross space in the Improvements with no 
consent or approval of Landlord or Lender being required or necessary 
("Preapproved Sublet").  Other than pursuant to a Preapproved Sublet, 
during the Initial Term, no portion of the Leased Premises shall be 
subleased during the Term to any other Person without the prior written 
consent of Landlord and Lender, which consent shall not be unreasonably 
withheld or delayed, and which consent shall be granted or withheld based 
on a review of the following criteria as they relate to the proposed 
sublessee:  (1) credit, (2) capital structure, (3) management, (4) 
operating history and (5) the proposed use of the sublet portion of the 
Improvements, taking into account factors related to the proposed 
subtenant's use of the Leased Premises such as environmental concerns.  
Landlord and Lender shall be deemed to have acted reasonably in granting 
or withholding consent if such grant or disapproval is based on their 
reasonable review of the above-described criteria.

        (i)     After the Initial Term, if Tenant desires to sublet any 
portion of the Leased Premises other than as  permitted by the first 
sentence of Paragraph 21(b) above, then Tenant shall, not less than 
fifteen (15) days prior to the date on which it desires to enter into 
such sublease, submit to Landlord and Lender such information as Landlord 
and Lender reasonably request regarding the identity and credit of the 
proposed subtenant.  Landlord and Lender shall review such information 
and shall, no later than the fifteenth (15th) day following receipt of 
such information, approve or disapprove the proposed sublease.  Such 
approval shall be deemed given if the net worth of the proposed subtenant 
is greater than or equal to the net worth of the Tenant as shown on its 
then most recently prepared financial statements, and otherwise such 
approval shall not be unreasonably withheld, conditioned or delayed.

        (j)     If Tenant assigns all its rights and interest under this 
Lease, the assignee under such assignment shall expressly assume all the 
obligations of Tenant hereunder, actual or contingent, including 
obligations of Tenant which may have arisen on or prior to the date of 
such assignment, including the obligation to comply with Exhibit "E", by 
a written instrument delivered to Landlord at the time of such 
assignment.  Each sublease of any of the Leased Premises shall be subject 
and subordinate to the provisions of this Lease.  No assignment or 
sublease made as permitted by this Paragraph 21 shall affect or reduce 
any of the obligations of Tenant hereunder or under any document executed 
by Tenant in favor of or for the benefit of Lender, and all such 
obligations shall continue in full force and effect as obligations of a 
principal and not as obligations of a guarantor, as if no assignment or 
sublease had been made.  No assignment or sublease shall impose any 
additional obligations on Landlord under this Lease.

        (k)     With respect to any Preapproved Assignment or Preapproved 
Sublet, Tenant shall provide to Landlord and to Lender legal opinions and 
other information reasonably required by Landlord and Lender to establish 
that any proposed Preapproved Assignment or Preapproved Sublet satisfies 
the criteria set forth above.

        (l)     Tenant shall, within ten (10) days after the execution and 
delivery of any assignment or sublease consented to by Landlord and 
Lender , deliver a duplicate original copy thereof to Landlord and Lender 
which, in the event of an assignment, shall be in recordable form.

        (m)     As security for performance of its obligations under this 
Lease, Tenant hereby grants, conveys and assigns to Landlord all right, 
title and interest of Tenant in and to all subleases hereinafter entered 
into for any or all of the Leased Premises, any and all extensions, 
modifications and renewals thereof and all rents, issues and profits 
therefrom.  Landlord hereby grants to Tenant a license to collect and 
enjoy all rents and other sums of money payable under any sublease of any 
of the Leased Premises, provided, however, that Landlord shall have the 
absolute right at any time during the existence of an Event of Default, 
upon notice to Tenant and any subtenants, to revoke said license and to 
collect such rents and sums of money and to retain the same.  Tenant 
shall not consent to, cause or allow any modification or alteration of 
any of the terms,  conditions or covenants of any of the subleases or the 
termination thereof, without the prior written approval of Landlord, 
which consent shall not be unreasonably withheld, nor shall Tenant do nor 
permit anything to be done, the doing of which, nor omit or refrain from 
doing anything, the omission of which, will or could be a breach of or 
default in the terms of any of the subleases.

        (n)     Tenant shall have no right or power to grant a mortgage on, 
or to pledge its leasehold interest in, or otherwise encumber its 
interest under this Lease or any sublease of the Leased Premises, and any 
such mortgage, pledge or encumbrance made in violation of this 
Paragraph 21 shall be void.  Tenant shall not permit any subtenant to 
mortgage, pledge or otherwise encumber its subleasehold interest in the 
Leased Premises.

        (o)     Subject to Tenant's rights under Paragraph 35, Landlord may 
sell or transfer the Leased Premises at any time without Tenant's consent 
to any third party (each a "Third Party Purchaser"), provided, that so 
long as no Event of Default exists either at the time Landlord enters 
into an agreement of sale for the purchase of the Leased Premises or on 
the date of conveyance to a Third Party Purchaser, Landlord shall not 
sell the Leased Premises to any Person whose primary business is the 
manufacturing of equipment that makes masks for the semi-conductor 
industry.  In the event of any such transfer, Tenant shall attorn to any 
Third Party Purchaser as Landlord so long as such Third Party Purchaser 
and Landlord notify Tenant in writing of such transfer and such Third 
Party Purchaser assumes in writing the obligations of Landlord under this 
Lease.  At the request of Landlord, Tenant will execute such documents 
confirming the agreement referred to above and such other agreements as 
Landlord may reasonably request, provided that such agreements do not 
increase the liabilities and obligations of Tenant hereunder.

        22.     Events of Default.

        (a)     The occurrence of any one or more of the following (after 
expiration of any applicable cure period as provided in Paragraph 22(b)) 
shall, at the sole option of Landlord, constitute an "Event of Default" 
under this Lease: 

                (i)  a failure by Tenant to make any payment of any Monetary
Obligation, regardless of the reason for such failure;

                (ii)  a failure by Tenant duly to perform and observe, or a
violation or breach of, any other provision hereof not otherwise
specifically mentioned in this Paragraph 22(a);

                (iii)  any representation or warranty made by Tenant herein
or in any certificate, demand or request made pursuant hereto proves to be
incorrect, now or hereafter, in any material respect;

                (iv)  a default beyond any applicable cure period or at
maturity by Tenant or any Subsidiary of Tenant in any payment of principal
or interest on any obligations for borrowed money having an outstanding
principal balance of $10,000,000 or more in the aggregate, or in the
performance of any other provision contained in any instrument under which
any such obligation is created or secured (including the breach of any
covenant thereunder), (x) if such payment is a payment at maturity or a
final payment, or (y) if a result of such default is to cause such
obligation to be accelerated prior to its stated maturity;

                (v)  a default by Tenant or any Subsidiary of Tenant beyond
any applicable cure period in the payment of rent under, or in the
performance of any other material provision of, any other lease or leases
that have, in the aggregate, rental obligations over the terms thereof of
$10,000,000 or more in the aggregate if the landlord under any such lease or
leases commences to terminate such lease or leases, dispossess Tenant or any
Subsidiary or accelerate the rent payable thereunder;

                (vi)  a final, non-appealable judgment or judgments for the
payment of money in excess of $10,000,000 (less any amounts payable from the
proceeds of insurance) in the aggregate shall be rendered against Tenant or
any Subsidiary and the same shall not be payable from the proceeds of
insurance and shall remain undischarged, unbonded or unsatisfied for a
period of sixty (60) consecutive days;

                (vii)  Tenant shall breach any Covenant or an Intended
Transaction or a Non-Preapproved Assignment shall occur and Tenant shall
have failed to comply with the provisions of Paragraph 21(d) through (f) or
Paragraph 33, as applicable;

                (viii)  Tenant or any Significant Subsidiary of Tenant shall
(A) voluntarily be adjudicated a bankrupt or insolvent, (B) seek or consent
to the appointment of a receiver or trustee for itself or for the Leased
Premises, (C) file a petition seeking relief under the bankruptcy or other
similar laws of the United States, any state or any jurisdiction, (D) make a
general assignment for the benefit of creditors, or (E) be unable to pay its
debts as they mature;

                (ix)  a court shall enter an order, judgment or decree
appointing, without the consent of Tenant or any Significant Subsidiary of
Tenant, a receiver or trustee for it or for any of the Leased Premises or
approving a petition filed against Tenant or any Significant Subsidiary
which seeks relief under the bankruptcy or other similar laws of the United
States, any state  or any jurisdiction, and such order, judgment or decree
shall remain undischarged or unstayed ninety (90) days after it is entered;

                (x)  the Leased Premises shall have been vacated (i.e.,
ceased to be operated on a consistent basis) except as permitted under, and
subject to the terms and conditions of, Paragraph 38 hereof or the Leased
Premises shall have been abandoned;

                (xi)  Tenant or any Significant Subsidiary of Tenant shall
be liquidated or dissolved or shall begin proceedings towards its
liquidation or dissolution;

                (xii)  the estate or interest of Tenant or any Significant
Subsidiary of Tenant in any of the Leased Premises shall be levied upon or
attached in any proceeding and such estate or interest is about to be sold
or transferred or such process shall not be vacated or discharged within
sixty (60) days after it is made;

                (xiii)  a failure by Tenant, following any notice and an
opportunity to cure, to perform or observe, or a violation or breach of, or
a misrepresentation by Tenant under any provision of any Assignment or any
other document between Tenant and Lender that, as to such Assignment or
other document, (A) recites that a breach, violation or misrepresentation by
Tenant thereunder will cause a default under the Loan and (B) provides that
Lender will give to Tenant any notice of such default that it is required to
give to Landlord, if such failure, violation, breach or misrepresentation
gives rise to a default beyond any applicable cure period with respect to
any Loan;

                (xiv)  a failure by Tenant to maintain in effect any
occupancy permit for the Leased Premises or permit required under any
Environmental Law;

                (xv)  an Event of Default shall have occurred and be
continuing under the Construction Agency Agreement or the Completion
Agreement; or

                (xvi)  Tenant shall have failed to occupy Building 4 by 
August 1, 1999.

        (b)     No notice or cure period shall be required in any one or more 
of the following events:  (A) except as otherwise set forth below, the 
occurrence of an Event of Default under clause (i), (iv), (v), (vi), 
(vii), (viii), (ix), (x), (xi), (xii), (xiii), (xv) or (xvi) of 
Paragraph 22(a); (B) the default consists of a failure to provide any 
insurance required by Paragraph 16 or an assignment or sublease entered 
into in violation of Paragraph 21; or (C) the default is such that any 
delay in the exercise of a remedy by Landlord could reasonably be 
expected to cause irreparable non-monetary harm to Landlord.  If the 
default consists of the failure to pay any Monetary Obligation under 
clause (i) of Paragraph 22(a), the applicable cure period shall be five 
(5) days from the date on which notice is given except that if the 
failure is the failure to pay Basic Rent no notice shall be required and 
only the five (5) day cure period shall be applicable, but in any event 
Landlord shall not be obligated to allow any cure period for or, if 
required, give notice of, any such default more than twice within any 
Lease Year.  If the default consists of a default under clauses (iv), (v) 
or (x) the applicable cure period shall be ten (10) days from the date on 
which notice is given provided that (X) with respect to a default under 
clause (iv) or (v) Tenant immediately gives to Landlord notice of 
acceleration or failure to pay at maturity or the exercise of remedies by 
a landlord or (Y) with respect to a default under clause (x) Tenant 
immediately give to Landlord notice that it has vacated the Leased 
Premises.  If the default consists of a default under clauses (ii), (iii) 
or (xiv) of Paragraph 22(a), other than the events specified in clauses 
(B) and (C) of the first sentence of this Paragraph 22(b), the applicable 
cure period shall be twenty (20) days from the date on which notice is 
given or, if the default cannot be cured within such twenty (20) day 
period, the cure period shall be extended for the period required to cure 
the default (but such cure period, including any extension, shall not in 
the aggregate exceed one hundred eighty (180) days), provided that Tenant 
shall commence to cure the default within the said twenty-day period and 
shall actively, diligently and in good faith proceed with and continue 
the curing of the default until it shall be fully cured.

        23.     Remedies and Damages Upon Default.

        (a)     If an Event of Default shall have occurred and is continuing, 
Landlord shall have the right, at its sole option, then or at any time 
thereafter, to the extent permitted by applicable law, to exercise its 
remedies and to collect damages from Tenant in accordance with this 
Paragraph 23, without demand upon or notice to Tenant except as otherwise 
provided in Paragraph 22(b) and this Paragraph 23.

                (i)  Landlord may give Tenant notice of Landlord's intention
to terminate this Lease on a date specified in such notice.  Upon such date,
this Lease, the estate hereby granted and all rights of Tenant hereunder
shall expire and terminate.  Upon such termination, Tenant shall immediately
surrender and deliver possession of the Leased Premises to Landlord in
accordance with Paragraph 26.  If Tenant does not so surrender and deliver
possession of the Leased Premises, Landlord may re-enter and repossess the
Leased Premises, with or without legal process, by peaceably entering the
Leased Premises and changing locks or by summary proceedings, ejectment or
any other lawful means or procedure.  Upon or at any time after taking
possession of the Leased Premises, Landlord may, by peaceable means or legal
process, remove any Persons or property therefrom.  Landlord shall be under
no liability for or by reason of any such entry, repossession or removal. 
Notwithstanding such entry or repossession, Landlord may (A) exercise the
remedy set forth in and collect the damages permitted by Paragraph
23(a)(iii) or (B) collect the damages set forth in Paragraph 23(c).

                (ii)  After repossession of the Leased Premises pursuant to
clause (i) above, Landlord shall have the right to relet any of the Leased
Premises to such tenant or tenants, for such term or terms, for such rent,
on such conditions and for such uses as Landlord in its sole discretion may
determine, and collect and receive any rents payable by reason of such
reletting.  Landlord may make such Alterations in connection with such
reletting as it may deem advisable in its sole discretion.  Notwithstanding
any such reletting, Landlord may collect the damages set forth in Paragraph
23(c).

                (iii)  To the extent permitted by applicable law, Landlord
may, upon notice to Tenant, require Tenant to make an irrevocable offer to
terminate this Lease upon payment to Landlord of an amount (the "Default
Termination Amount") specified in the next sentence.  The "Default
Termination Amount" shall be the greater of (A) the Fair Market Value of the
Leased Premises, or (B) the Acquisition Cost and the Prepayment Premium
which Landlord will be required to pay in prepaying any Loan with proceeds
of the Default Termination Amount.  Upon such notice to Tenant, Tenant shall
be deemed to have made such offer and shall, if requested by Landlord,
within ten (10) days following such request deposit with Landlord as payment
against the Default Termination Amount the amount described in (B) above,
and Landlord and Tenant shall promptly commence to determine Fair Market
Value.  Within thirty (30) days after the Fair Market Value Date, Landlord
shall accept or reject such offer.  If Landlord accepts such offer then, on
the tenth (10th) business day after such acceptance, Tenant shall pay to
Landlord the Default Termination Amount and, at the request of Tenant,
Landlord will convey the Leased Premises to Tenant or its designee in
accordance with Paragraph 20.  Any rejection by Landlord of such offer
(which rejection shall have been consented to in writing by Lender) shall
have no effect on any other remedy Landlord may have under this Lease.

        (b)     In addition to its other rights under this Lease, Landlord 
has the remedy described in California Civil Code Section 1951.4 which 
provides substantially as follows:  Landlord may continue the Lease in 
effect after Tenant's breach and abandonment and recover the Rent as it 
becomes due.  In accordance with California Civil Code Section 1951.4 (or 
any successor statute), Tenant acknowledges that in the event Tenant 
breaches this Lease and abandons the Leased Premises, 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 its rights and 
remedies under this Lease, including the right to recover the Rent as it 
becomes due under this Lease.  Tenant acknowledges that the limitations 
on subletting and assignment set forth in Paragraph 21 are reasonable.  
Acts of maintenance or preservation or efforts to relet the Leased 
Premises or the appointment of a receiver upon initiative of Landlord to 
protect Landlord's interest under this Lease shall not constitute a 
termination of Tenant's right to possession.

        (c)     If Landlord elects to terminate this Lease upon the 
occurrence of an Event of Default, Landlord may collect from Tenant 
damages computed in accordance with the following  provisions in addition 
to Landlord's other remedies under this Lease:

                (i)  the worth at the time of award of any unpaid Rent 
which has been earned at the time of such termination; plus

                (ii)  the worth at the time of award of the amount by which
any 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; plus

                (iii)  the worth at the time of award of the amount by which
the unpaid Rent for the balance of the Term after the time of award exceeds
the amount of such rental loss that Tenant proves could be reasonably
avoided, plus

                (iv)  any other reasonable Cost necessary to compensate
Landlord for all the detriment proximately caused by Tenant's failure to
perform its obligations under this Lease, including out of pocket costs
incurred by Lender, or which in the ordinary course of things would be
likely to result therefrom including, without limitation, brokerage
commissions, the cost of repairing and reletting the Leased Premises and
reasonable attorneys' fees; plus

                (v)  at Landlord's election, such other amounts in addition
to or in lieu of the foregoing as may be permitted from time to time by
applicable state law.  Damages shall be due and payable from the date of
termination.

        (d)     For purposes of clauses (i) and (ii) of Paragraph 23(c), the 
"worth at the time of award" shall be computed by adding interest at the 
Default Rate to the past due Rent.  For the purposes of clause (iii) of 
Paragraph 23(c), the "worth at the time of award" shall be computed by 
discounting such amount at the discount rate of the Federal Reserve Bank 
of San Francisco at the time of the award, plus one percent (1%).

        (e)     Landlord shall be entitled to apply the Security Deposit to 
any amounts due under Paragraph 23(c) if this Lease shall be terminated, 
or, if this Lease shall remain in full force and effect, to any amounts 
due under Paragraph 23(b) or in the following order:  (i) to past due 
Basic Rent, (ii) to other Monetary Obligations then due and owing and 
(iii) to installments of Basic Rent in inverse order of maturity 
commencing with the last installment of the Term.

        (f)     Notwithstanding anything to the contrary herein contained, in 
lieu of or in addition to any of the foregoing remedies and damages, 
Landlord may exercise any remedies and collect any damages available to 
it at law or in equity.  If Landlord is unable to obtain full 
satisfaction pursuant to the  exercise of any remedy, it may pursue any 
other remedy which it has hereunder or at law or in equity.

        (g)     Landlord shall not be required to mitigate any of its damages 
hereunder unless required to by applicable Law.  If any Law shall validly 
limit the amount of any damages provided for herein to an amount which is 
less than the amount agreed to herein, Landlord shall be entitled to the 
maximum amount available under such Law.

        (h)     No termination of this Lease, repossession or reletting of 
the Leased Premises, exercise of any remedy or collection of any damages 
pursuant to this Paragraph 23 shall relieve Tenant of any Surviving 
Obligations.

        (i)     WITH RESPECT TO ANY REMEDY OR PROCEEDING OF LANDLORD 
HEREUNDER, TENANT WAIVES ANY RIGHT TO A TRIAL BY JURY.  Tenant agrees 
that this Lease constitutes a written consent to waiver of trial by jury 
pursuant to the provisions of California Code of Civil Procedure Section 
631 and Tenant does hereby appoint Landlord its true and lawful 
attorney-in-fact, which appointment is coupled with an interest, and 
Tenant does hereby authorize and empower Landlord, in the name, place and 
stead of Tenant, to file this Lease with the clerk or judge of any court 
of competent jurisdiction as statutory written consent to waiver of trial 
by jury.

        (j)     During the existence of any Event of Default, Landlord shall 
have the right (but no obligation) to perform any act required of Tenant 
hereunder and, if performance of such act requires that Landlord enter 
the Leased Premises, Landlord may enter the Leased Premises for such 
purpose.

        (k)     No failure of Landlord (i) to insist at any time upon the 
strict performance of any provision of this Lease or (ii) to exercise any 
option, right, power or remedy contained in this Lease shall be construed 
as a waiver, modification or relinquishment thereof.  A receipt by 
Landlord of any sum in satisfaction of any Monetary Obligation with 
knowledge of the breach of any provision hereof shall not be deemed a 
waiver of such breach, and no waiver by Landlord of any provision hereof 
shall be deemed to have been made unless expressed in a writing signed by 
Landlord.

        (l)     Tenant hereby waives and surrenders, for itself and all those 
claiming under it, including creditors of all kinds, (i) any right and 
privilege which it or any of them may have under any present or future 
Law to redeem any of the Leased Premises or to have a continuance of this 
Lease after termination of this Lease or of Tenant's right of occupancy 
or possession pursuant to any court order or any provision hereof, and 
(ii) the benefits of any present or future Law which exempts property 
from liability for debt or for distress for rent.

        (m)     Except as otherwise provided herein, all remedies are 
cumulative and concurrent and no remedy is exclusive of any other remedy. 
 Each remedy may be exercised at any time an Event of Default has 
occurred and is continuing and may be exercised from time to time.  No 
remedy shall be exhausted by any exercise thereof.

        24.     Notices.  All notices, demands, requests, consents, 
approvals, offers, statements and other instruments or communications 
required or permitted to be given pursuant to the provisions of this 
Lease shall be in writing and shall be deemed to have been given for all 
purposes when delivered in person or by Federal Express or other reliable 
24-hour delivery service, addressed to the other party at its address 
stated on page 1 of this Lease.  A copy of any notice given by Tenant to 
Landlord shall simultaneously be given by Tenant to Reed Smith Shaw & 
McClay, 2500 One Liberty Place, Philadelphia, PA  19103, Attention:  
Chairman, Real Estate Department.  For the purposes of this Paragraph, 
any party may substitute another address stated above (or substituted by 
a previous notice) for its address by giving fifteen (15) days' notice of 
the new address to the other party, in the manner provided above.

        25.     Estoppel Certificate.  At any time upon not less than ten 
(10) days' prior written request by any of Landlord, Tenant or Lender 
(the "Requesting Party") to Landlord or Tenant, as applicable, (the 
"Responding Party"), the Responding Party shall deliver to the Requesting 
Party a statement in writing, executed by an authorized officer of the 
Responding Party, certifying (a) that, except as otherwise specified, 
this Lease is unmodified and in full force and effect, (b) the dates to 
which Basic Rent, Additional Rent and all other Monetary Obligations have 
been paid, (c) that, to the knowledge of the signer of such certificate 
and except as otherwise specified, no default by either Landlord or 
Tenant exists hereunder, (d) such other matters as the Requesting Party 
may reasonably request, and (e) if Tenant is the Responding Party that, 
except as otherwise specified, there are no proceedings pending or, to 
the knowledge of the signer, threatened, against Tenant before or by any 
court or administrative agency which, if adversely decided, would 
materially and adversely affect the financial condition and operations of 
Tenant or Tenant's ability to perform its obligations under this Lease.  
Any such statements by the Responding Party may be relied upon by the 
Requesting Party, any Person whom the Requesting Party notifies the 
Responding Party in its request for the Certificate is an intended 
recipient or beneficiary of the Certificate, any Lender or their 
assignees and by any prospective purchaser or mortgagee of any of the 
Leased Premises.  Any certificate required under this Paragraph 25 and 
delivered by Tenant shall state that, in the opinion of each person 
signing the same, he or she has made such examination or investigation as 
is necessary to enable him or her to express an informed opinion as to 
the subject matter of such  certificate, and shall briefly state the 
nature of such examination or investigation.

        26.     Surrender.  Upon the expiration or earlier termination of 
this Lease, Tenant shall peaceably leave and surrender the Leased 
Premises to Landlord in the same condition in which the Leased Premises 
was at the commencement of this Lease, except as repaired, rebuilt, 
restored, altered, replaced or added to as permitted or required by any 
provision of this Lease, and except for ordinary wear and tear.  Upon 
such surrender, Tenant shall (a) remove from the Leased Premises all 
property which is owned by Tenant or third parties other than Landlord 
and (b) repair any damage caused by such removal.  Property not so 
removed shall become the property of Landlord, and Landlord may 
thereafter cause such property to be removed from the Leased Premises.  
The cost of removing and disposing of such property and repairing any 
damage to any of the Leased Premises caused by such removal shall be paid 
by Tenant to Landlord upon demand.  Landlord shall not in any manner or 
to any extent be obligated to reimburse Tenant for any such property 
which becomes the property of Landlord pursuant to this Paragraph 26.

        27.     No Merger of Title.  There shall be no merger of the 
leasehold estate created by this Lease with the fee estate in any of the 
Leased Premises by reason of the fact that the same Person may acquire or 
hold or own, directly or indirectly, (a) the leasehold estate created 
hereby or any part thereof or interest therein and (b) the fee estate in 
any of the Leased Premises or any part thereof or interest therein, 
unless and until all Persons having any interest in the interests 
described in (a) and (b) above which are sought to be merged shall join 
in a written instrument effecting such merger and shall duly record the 
same.

        28.     Books and Records.

        (a)     Tenant shall permit Landlord and Lender by their respective 
agents, accountants and attorneys, upon not less than 48 hours notice to 
Tenant (except that if an Event of Default exists no notice shall be 
required), to visit and inspect the Leased Premises and examine (and make 
copies of) the records and books of account and to discuss the finances 
and business with the officers of Tenant and its independent accountants, 
at such reasonable times as may be requested by Landlord.  Upon the 
request of Lender (either telephonically or in writing), Tenant shall 
provide to Lender (with a copy to Landlord) such other information as 
Lender shall reasonably request.

        (b)     Tenant shall deliver to Landlord and to Lender within ninety 
(90) days of the close of each fiscal year, annual audited financial 
statements of Tenant and its consolidated Subsidiaries prepared by 
nationally recognized independent certified public accountants.  Tenant 
shall also furnish to Landlord and Lender within forty-five (45) days of 
the close of each of the remaining three (3) fiscal quarters unaudited 
financial statements of Tenant, certified by Tenant's chief financial 
officer, and all other quarterly reports of Tenant, and all filings, if 
any, of Form 10-K, Form 10-Q and other required  filings with the 
Securities and Exchange Commission pursuant to the provisions of the 
Securities Exchange Act of 1934, as amended, or any other Law.  All 
financial statements of Tenant shall be prepared in accordance with GAAP 
(as defined in Exhibit "E" hereto) consistently applied.  All annual 
financial statements shall be accompanied (x) by an opinion of said 
accountants stating that (1) there are no qualifications as to the scope 
of the audit and (2) the audit was performed in accordance with GAAP and 
(y) by the affidavit of the president or a vice president of Tenant, 
dated within five (5) days of the delivery of such statement, stating 
that (i) the affiant knows of no Event of Default, or event which, upon 
notice or the passage of time or both, would become an Event of Default 
which has occurred and is continuing hereunder or, if any such event has 
occurred and is continuing, specifying the nature and period of existence 
thereof and what action Tenant has taken or proposes to take with respect 
thereto and (ii) except as otherwise specified in such affidavit, that 
Tenant has fulfilled all of its obligations under this Lease which are 
required to be fulfilled on or prior to the date of such affidavit.

        (c)     Landlord and its agents, accountants and attorneys, shall 
consider and treat on a confidential basis (i) any information contained 
in the books and records of Tenant, (ii) any copies of any books and 
records of Tenant, and any financial statements of Tenant pursuant to 
Paragraph 28(b) which are delivered to or received by them.  Neither 
Landlord nor its agents, accountants and attorneys, shall disclose any 
information contained in Tenant's books and records nor distribute copies 
of any of such books and records nor Tenant's financial statements to any 
other Persons without the prior written consent of the chief operating 
officer of Tenant.

        (d)     The restrictions contained in Paragraph 28(c) shall not 
prevent disclosure by Landlord of any information in any of the following 
circumstances:

                (i)  Upon the order of any court or administrative 
agency to the extent required by such order and not 
effectively stayed or by appeal or otherwise;

                (ii)  Upon the request, demand or requirement of any 
regulatory agency or authority having jurisdiction over such 
party, including the United States Securities and Exchange 
Commission (whether or not such request or demand has the 
force of law);

                (iii)  That has been publicly disclosed by Tenant in a 
press release or other public announcement of general 
circulation or filed with the United States Securities and 
Exchange Commission or that has become public through no 
breach by the recipient of these confidentiality obligations;

                (iv)  To counsel or accountants or other agents for 
Landlord or counsel or accountants or other agents  for such 
other Person who has agreed to abide by the provisions of 
Paragraph 28(c);

                (v)  While an Event of Default exists, in connection 
with the exercise of any right or remedy under this Lease or 
any other related document;

                (vi)  Independently developed by Landlord to the extent 
that confidential information provided by Tenant is not used 
to develop such information;

                (vii)  With respect to financial information and 
information that Landlord or its attorneys deem to be 
material in any reporting to the shareholders of Landlord or 
the shareholders or prospective shareholders (whether through 
a registered public offering or otherwise) of Landlord's 
parent company;

                (viii)  In connection with any sale or financing of the 
Leased Premises, provided that any recipient of such 
information who is a prospective purchaser of the Leased 
Premises (except for a purchaser that purchases all or 
substantially all of the assets of Landlord's parent company) 
shall agree to be bound by the terms of Paragraph 28(c);

                (ix)  From Landlord to Lender or to any prospective 
purchaser of the Leased Premises or to the National 
Association of Insurance Commissioners; or

                (x)  As otherwise required by Law.

        29.     Determination of Value.

        (a)     Whenever a determination of Fair Market Value or Fair Market 
Rental Value is required pursuant to any provision of this Lease, such 
Fair Market Value or Fair Market Rental Value shall be determined in 
accordance with the following procedure:

                (i)  Landlord and Tenant shall endeavor to agree upon such
Fair Market Value within thirty (30) days after the date (the "Applicable
Initial Date") on which (A) Tenant provides Landlord with notice of its
intention to terminate this Lease and purchase the Leased Premises pursuant
to Paragraph 18, (B) Landlord provides Tenant with notice of its intention
to redetermine Fair Market Value pursuant to Paragraph 20(c), (C) Landlord
provides Tenant with notice of Landlord's intention to require Tenant to
make an offer to terminate this Lease pursuant to Paragraph 23(a)(iii), (D)
Tenant provides Landlord with an Intended Assignment Offer under Paragraph
21(d), (E) the date on which Landlord accepts Tenant's offer pursuant to
Paragraph 33(c), (F) the date on which Landlord accepts the Third Party
Purchaser's offer pursuant to Paragraph 35(c) and (G) the date on which
Landlord accepts Tenant's offer pursuant to Paragraph 38(d).  Landlord and
Tenant shall endeavor to agree on Fair Market Rental Value on the date
(also, an "Applicable Initial Date") which is six (6) calendar months prior
to the expiration of the then current Term unless Tenant has previously
exercised its option pursuant to Paragraph 5(b) not to have the Term
automatically extended.  Upon reaching such agreement, the parties shall
execute an agreement setting forth the amount of such Fair Market Value or
Fair Market Rental Value, as the case may be.

                (ii)  If the parties shall not have signed such agreement
within thirty (30) days after the Applicable Initial Date, Tenant shall
within fifty (50) days after the Applicable Initial Date select an appraiser
and notify Landlord in writing of the name, address and qualifications of
such appraiser.  Within twenty (20) days thereafter, Landlord shall select
an appraiser and notify Tenant of the name, address and qualifications of
such appraiser.  Such two appraisers shall endeavor to agree upon Fair
Market Value or Fair Market Rental Value, as the case may be, based on an
appraisal made by each of them as of the Relevant Date.  If such two
appraisers shall agree upon a Fair Market Value or Fair Market Rental Value,
as the case may be, the amount of such Fair Market Value or Fair Market
Rental Value, as the  case may be, as so agreed shall be binding and
conclusive.

                (iii)  If such two appraisers shall be unable to agree upon
a Fair Market Value or Fair Market Rental Value, as the case may be, within
twenty (20) days after the selection of an appraiser by Landlord, then such
appraisers shall advise Landlord and Tenant of their respective
determination of Fair Market Value or Fair Market Rental Value, as the case
may be, and shall select a third appraiser to make the determination of Fair
Market Value or Fair Market Rental Value, as the case may be, which
determination as to the selection of the third appraiser shall be binding
and conclusive upon Landlord and Tenant.

                (iv)  If such two appraisers shall be unable to agree upon
the designation of a third appraiser within ten (10) days after the
expiration of the twenty (20) day period referred to in clause (iii) above,
or if such third appraiser does not make a determination of Fair Market
Value or Fair Market Rental Value, as the case may be, within twenty (20)
days after his selection, then such third appraiser or a substituted third
appraiser, as applicable, shall, at the request of either party hereto (with
notice to the other party), be appointed by the President or Chairman of the
American Arbitration Association in San Francisco, California.  The
determination of Fair Market Value or Fair Market Rental Value, as the case
may be, made by the third appraiser appointed pursuant hereto shall be made
within twenty (20) days after such appointment.

                (v)  Fair Market Value or Fair Market Rental Value, as the
case may be, shall be the average of the determination of Fair Market Value
or Fair Market Rental Value, as the case may be, made by the third appraiser
and the determination of Fair Market Value or Fair Market Rental Value, as
the case may be, made by the appraiser (pursuant to Paragraph 29(a)(iii)
hereof) whose determination of Fair Market Value or Fair Market Rental
Value, as the case may be, is nearest to that of the third appraiser.  Such
average shall be binding and conclusive upon Landlord and Tenant.

                (vi)  All appraisers selected or appointed pursuant to this
Paragraph 29(a) shall (A) be independent  qualified MAI appraisers (B) have
no right, power or authority to alter or modify the provisions of this
Lease, (C) utilize the methodology for determining Fair Market Value set
forth in Paragraph 29(c) or the methodology for determining Fair Market
Rental Value as set forth in Paragraph 29(d), and (D) be registered in the
State if the State provides for or requires such registration.  The Cost of
the procedure described in this Paragraph 29(a) above shall be borne equally
by Landlord and Tenant, except that the Cost with respect to the appraisals
performed under Paragraphs 21, 23, 33 or 38 shall be paid by Tenant and the
Cost with respect to the appraisals performed under Paragraph 35 shall be
paid by the Third Party Purchaser.

        (b)     If, by virtue of any delay, Fair Market Value is not 
determined by the expiration or termination of the then current Term, 
then the date on which the Term would otherwise expire or terminate shall 
be extended to the date specified for termination in the particular 
provision of this Lease pursuant to which the determination of Fair 
Market Value is being made.  If, by virtue of any delay, Fair Market 
Rental Value is not determined by the expiration or termination of the 
then current Term, then until Fair Market Rental Value is determined, 
Tenant shall continue to pay Basic Rent during the succeeding Renewal 
Term in the same amount which it was obligated under this Lease to pay 
prior to the commencement of the Renewal Term.  When Fair Market Rental 
Value is determined, the appropriate Basic Rent shall be calculated 
retroactive to the commencement of the Renewal Term and Tenant shall 
either receive a refund from Landlord (in the case of an overpayment) or 
shall pay any deficiency to Landlord (in the case of an underpayment).

        (c)     Fair Market Value shall be determined as follows:  The 
appraisers shall add (i) the present value of the Rent for the remaining 
Term, (with assumed increases in the CPI to be determined by the 
appraisers) using a discount rate (which may be determined by an 
investment banker) based on the creditworthiness of Tenant and (ii) the 
present value of the Fair Market Value of the Leased Premises as of the 
end of the then current Term (without necessarily making any assumption 
as to whether the Tenant will or will not exercise any remaining 
options), using a yield rate required by investors for property having 
similar characteristics, without consideration given to Tenant's credit 
rating or creditworthiness.  In determining the value under (ii), the 
appraisers shall, insofar as possible, consider properties having similar 
characteristics and in reasonable proximity to the Leased Premises, but 
the appraisers shall not be precluded from considering properties that do 
not have "clean" rooms, properties that are (or are not) located in 
Hayward, California or properties having a different use than the Leased 
Premises.  The appraisers shall further assume that no default then 
exists under the Lease, that Tenant has complied (and will comply) with 
all provisions of the Lease, and that Tenant has not violated (and will 
not violate) any of the Covenants.

        (d)     In determining Fair Market Rental Value, the appraisers shall 
determine the amount that a willing tenant would pay, and a willing 
landlord of a building having similar characteristics and in reasonable 
proximity to the Leased Premises would accept, at arm's length, taking 
into account:  (a) the age, quality, and condition of the Improvements; 
(b) that the Leased Premises may be leased as a whole or substantially as 
a whole to a single user or leased to multiple users; (c) a lease term of 
five (5) years; (d) an absolute triple net lease; and (e) such other 
items that professional real estate appraisers customarily consider.  In 
determining Fair Market Rental Value, the appraisers shall, insofar as 
possible, consider properties having similar characteristics and in 
reasonable proximity to the Leased Premises, but the appraisers shall not 
be precluded from considering properties that do not have "clean" rooms, 
properties that are (or are not) located in Hayward, California or 
properties having a different use than the Leased Premises.

        30.     Non-Recourse as to Landlord.  Anything contained herein to 
the contrary notwithstanding, any claim based on or in respect of any 
liability of Landlord under this Lease shall be enforced only against the 
Leased Premises and not against any other assets, properties or funds of 
(a) Landlord, (b) any director, officer, general partner, shareholder, 
member, limited partner, advisor, employee or agent of Landlord or any 
general partner of Landlord or any of its general partners (or any legal 
representative, heir, estate, successor or assign of any thereof), 
(c) any predecessor or successor partnership or corporation (or other 
entity) of Landlord or any of its general partners, shareholders, 
officers, directors, advisors, employees or agents, either directly or 
through Landlord or its general partners, shareholders, officers, 
directors, advisors, employees or agents or any predecessor or successor 
partnership or corporation (or other entity), or (d) any other Person 
(including W.P. Carey Incorporated) affiliated with any of the foregoing, 
or any director, officer, advisor, employee or agent of any thereof.

        31.     Financing.

        (a)     Tenant covenants and agrees that it shall pay all reasonable 
costs and expenses incurred by Landlord in refinancing the Initial Loan, 
including the cost of any mortgage broker's fees, "points" or commitment 
fees payable to the Lender, survey, title and environmental costs and 
costs of Landlord's and Lender's counsel.  Payment of such costs shall be 
made within ten (10) days following receipt of a written request from 
Landlord accompanied by invoices for the amounts requested.

        (b)     If Landlord desires to obtain or refinance any Loan, Tenant 
shall negotiate in good faith with Landlord concerning any request made 
by any Lender or proposed Lender for changes or modifications in this 
Lease.  In particular, Tenant shall agree, upon request of Landlord, to 
supply any such Lender with such notices and information as Tenant is 
required to give to Landlord hereunder and to extend the rights of 
Landlord hereunder to any such Lender and to consent to such financing if 
such consent is requested by such Lender.  Tenant shall provide any other 
consent or statement and shall execute any and all other documents that 
such Lender requires in connection with such financing, including any 
environmental indemnity agreement and subordination, non-disturbance and 
attornment agreement, so long as the same do not materially adversely 
affect any right, benefit or privilege of Tenant under this Lease or 
materially increase Tenant's obligations under this Lease.

        (c)     Except as provided in Paragraph 31(a) above, Tenant shall not 
be responsible for any fees or expenses associated with any of the 
transactions contemplated by this Paragraph 31.  Landlord shall reimburse 
Tenant for all reasonable costs and expenses incurred by Tenant in 
carrying out its obligations under this Paragraph 31 other than as 
provided in the foregoing Paragraph 31(a).

        32.     Subordination.  This Lease and Tenant's interest hereunder 
shall be subordinate to any Mortgage or other security instrument 
hereafter placed upon the Leased Premises by Landlord, and to any and all 
advances made or to be made thereunder, to the interest thereon, and all 
renewals, replacements and extensions thereof, provided that any such 
Mortgage or other security instrument (or a separate instrument in 
recordable form duly executed by the holder of any such Mortgage or other 
security instrument and delivered to Tenant) shall provide for the 
recognition of this Lease and all Tenant's rights hereunder unless and 
until an Event of Default exists or Landlord shall have the right to 
terminate this Lease pursuant to any applicable provision hereof all as 
set forth in a Subordination, Non-Disturbance and Attornment Agreement in 
form and substance reasonably satisfactory to Tenant.

        33.     Financial Covenants; Covenant Breach Offer.

        (a)     Until the expiration of the Initial Term, Tenant hereby 
covenants and agrees to comply with all the covenants and agreements (the 
"Covenants") described in Paragraphs 1 through 3 in Exhibit "E" hereto.

        (b)     If (i) Tenant intends to take any action or, with respect to 
Paragraph 1(b) of Exhibit "E", has knowledge that such action is intended 
to be taken by another Person, or such action occurs (such action, an 
"Intended Transaction") that would result in a breach of any Covenant set 
forth in Paragraph 1 or 2 of Exhibit "E" attached hereto or (ii) Tenant 
becomes aware that the Covenant set forth in Paragraph 3 of Exhibit "E" 
will be or has been breached (a "Covenant Breach"), then, not later than 
ninety (90) days prior to the Intended Transaction or the date on which 
Tenant obtains knowledge of any such action, in the case of (i) above, or 
immediately upon becoming aware that a Covenant Breach will occur or has 
occurred, in the case of (ii) above, Tenant shall submit to Landlord and 
Lender a description thereof specifying the Intended Transaction or the 
Covenant Breach, as the case may be, together with a rejectable offer of 
Tenant to purchase the Leased Premises (as required by, and in accordance 
with, the provisions of this Paragraph 33) and, if such offer is accepted 
by Landlord, Tenant shall purchase the Leased Premises within the time 
prescribed for such purchase (as provided in this Paragraph 33) and 
otherwise in accordance with the provisions of Paragraph 20 of this 
Lease.

        (c)     Tenant shall make an offer to purchase the Leased Premises no 
later than the date (the "Intended Transaction Closing Date") on which 
the Intended Transaction will occur (or, in the case of a Covenant 
Breach, no later than the earlier of ninety (90) days from the date 
Tenant becomes aware that a Covenant Breach has occurred or will occur) 
for a purchase price equal to the Offer Amount.

        (d)     If Landlord shall reject such offer by notice to Tenant, such 
notice to contain the written consent of Lender to  such rejection, not 
later than the thirtieth (30th) day following receipt of such offer by 
Landlord, then the Lease shall remain in full force and effect and the 
Intended Transaction or Covenant Breach, as the case may be, shall be 
deemed waived or acceptable by Landlord and Lender, respectively, and the 
waiver or acceptance shall remain in effect for the balance of the Term 
with respect to the specific Intended Transaction or specific set of 
facts giving rise to the Covenant Breach only.  No rejection of an offer 
under this Paragraph 33 shall be effective for any purpose unless 
consented to in writing by Lender.

        (e)     Unless Landlord shall have rejected such offer by the 
foregoing notice to Tenant not later than the thirtieth (30th) day 
following receipt of Tenant's offer by Landlord, Landlord shall be 
conclusively presumed to have accepted such offer.  If such offer is 
accepted by Landlord, Tenant shall pay to Landlord the Offer Amount on 
the Intended Transaction Closing Date (except that if the Fair Market 
Value of the Leased Premises shall not yet have been determined, Tenant 
shall pay to Landlord an amount equal to the Deposit Amount on the 
Intended Transaction Closing Date and any excess of the Fair Market Value 
of the Leased Premises over such sum shall be paid by Tenant to Landlord 
within ten (10) days of the determination of such Fair Market Value) and, 
provided that no Rent or any other charge is due and unpaid under this 
Lease as of the Intended Transaction Closing Date, and Tenant is 
otherwise in compliance with the terms of this Lease, Landlord shall 
convey to Tenant the Leased Premises in accordance with the provisions of 
Paragraph 20.

        (f)     Notwithstanding the foregoing, and only with respect to 
offers made solely in anticipation of an Intended Transaction or a 
Covenant Breach which Tenant anticipates will occur, if Tenant determines 
that the Intended Transaction or Covenant Breach will not occur, Tenant 
shall have the right to revoke its offer to purchase the Leased Premises 
by notice to Landlord received not later than fifteen (15) days prior to 
the anticipated Intended Transaction Closing Date (TIME BEING OF THE 
ESSENCE), provided that Tenant shall be obligated to pay all Costs of 
Landlord and Lender reasonably incurred as a result of the offer made by 
Tenant pursuant to this Paragraph 33.  Nothing provided herein shall 
constitute a waiver by Landlord of the obligation of Tenant to comply 
with the requirements of this Paragraph 33 if a subsequent Covenant 
Breach or subsequent Intended Transaction will occur or occurs.

        34.     Tax Treatment; Reporting.  Landlord and Tenant each 
acknowledge that each shall treat this transaction as a true lease for 
state law purposes and shall report this transaction as a lease for 
Federal income tax purposes.  For Federal income tax purposes each shall 
treat this Lease as a true lease with Landlord as the owner of the Leased 
Premises and Tenant as the lessee of such Leased Premises including:  
(1) treating Landlord as the owner of the property eligible to claim 
depreciation deductions under Section 167 or 168 of the  Internal Revenue 
Code of 1986 (the "Code") with respect to the Leased Premises, (2) Tenant 
reporting its Rent payments as a business expense under Section 162 of 
the Code, and (3) Landlord reporting the Rent payments as rental income.

        35.     Right of First Refusal.

        (a)     Except as otherwise provided in clause (e) of this 
Paragraph 35, and provided an Event of Default does not then exist, prior 
to selling the Leased Premises to any Third Party Purchaser, if Landlord 
shall enter into a contract for the sale of the Leased Premises with a 
Third Party Purchaser, (i) such contract shall be conditioned upon 
Tenant's failure to exercise its right under this Paragraph 35 and (ii) 
Landlord shall give written notice to Tenant of the contract for sale, 
together with a copy of the executed offer or contract and the name and 
business address of the Third Party Purchaser.

        (b)     For a period of thirty (30) days following receipt of such 
notice, Tenant shall have the right and option, exercisable by written 
notice to Landlord given within said thirty (30) day period, to elect to 
purchase the Leased Premises at the purchase price and upon all the terms 
and conditions set forth in such contract for sale except that no 
contingencies contained in such contract for sale as to environmental 
assessments, engineering studies, inspection of the Leased Premises, sale 
of other property, state of the title to or encumbrances on the Leased 
Premises which pertains to any exception of title created by, or suffered 
to exist by, Tenant, or any other condition or contingency to the Third 
Party Purchaser's obligation to purchase the Leased Premises which 
pertains to the condition of the Leased Premises, shall apply to Tenant's 
obligation to purchase the Leased Premises under this Paragraph 35, and 
Tenant shall be obligated to purchase the Leased Premises without any 
such condition or contingency.

        (c)     If at the expiration of the aforesaid thirty (30) day period 
Tenant shall have failed to exercise the aforesaid option, Landlord may 
sell the Leased Premises to such Third Party Purchaser upon the terms set 
forth in such contract.  For the purposes of Paragraph 35(a), the 
purchase price in any contract to purchase the Leased Premises which is 
received by Landlord between June 1, 2007 and May 31, 2008 shall be 
deemed to be "acceptable to Landlord" if such offer (i) is for an amount 
equal to or greater than the greater of (A) the sum of (1) Fair Market 
Value (which shall be determined in accordance with the procedure set 
forth in Paragraph 29 of this Lease, except that references to Tenant in 
Paragraphs 29(a) and (b) hereof shall mean Third Party Purchaser) and (2) 
the Prepayment Premium or (B) the sum of (1) the Acquisition Cost reduced 
by the principal payments made on the Note to the date of purchase and 
(2) the Prepayment Premium, (ii) provides that the purchaser pays  all 
costs in connection with such purchase, (iii) provides that such purchase 
price is payable in cash at the closing of the sale of the Leased 
Premises and (iv) the closing date for such purchase will occur not later 
than sixty (60) days following May 31, 2008.

        (d)     Except as otherwise specifically provided in the foregoing 
Paragraph 35(a), the closing date for any purchase of the Leased Premises 
by Tenant pursuant to this Paragraph 35 shall be on a date designated by 
Tenant, but not later than (i) ninety (90) days after the date of 
Tenant's notice to Landlord of its intention to purchase the Leased 
Premises upon the terms of the contract for sale with a Third Party 
Purchaser or (ii) the closing date provided in such contract for sale.  
At such closing Landlord shall convey the Leased Premises to Tenant in 
accordance with, and Tenant shall pay to Landlord the purchase price and 
other consideration set forth in, the applicable offer or contract.

        (e)     Tenant shall have the right during the Term to exercise the 
foregoing right of first refusal upon each proposed sale of the Leased 
Premises prior to May 31, 2008; provided, that if, following compliance 
with the procedure described in this Paragraph 35, a Third Party 
Purchaser does not purchase the Leased Premises, such event shall not 
count as an exercise of Tenant's right of first refusal.  NOTWITHSTANDING 
ANYTHING TO THE CONTRARY, IF TENANT FAILS TO EXERCISE THE RIGHT OF FIRST 
REFUSAL BY May 31, 2008, OR IF THIS LEASE TERMINATES OR THE TERM EXPIRES, 
SUCH RIGHT SHALL TERMINATE AND BE NULL AND VOID AND OF NO FURTHER FORCE 
AND EFFECT.

        (f)     If Tenant does not exercise its right of first refusal to 
purchase the Leased Premises and the Leased Premises are transferred to a 
Third Party Purchaser, Tenant will attorn to any Third Party Purchaser as 
Landlord so long as such Third Party Purchaser and Landlord notify Tenant 
in writing of such transfer.  At the request of Landlord, Tenant will 
execute such documents confirming the agreement referred to above and 
such other agreements as Landlord may reasonably request, provided that 
such agreements do not increase the liabilities and obligations of Tenant 
hereunder.

        (g)     The provisions of Paragraph 35(a) shall not apply to or 
prohibit (i) any mortgaging, subjection to deed of trust or other 
hypothecation of Landlord's interest in the Leased Premises, (ii) any 
sale of the Leased Premises pursuant to a private power of sale under or 
judicial foreclosure of any Mortgage or other security instrument or 
device to which Landlord's interest in the Leased Premises is now or 
hereafter subject, (iii) any transfer of Landlord's interest in the 
Leased Premises to a Lender, beneficiary under deed of trust or other 
holder of a security interest therein by deed in lieu of  foreclosure, 
(iv) any transfer of the Leased Premises to any governmental or 
quasi-governmental agency with power of condemnation, (v) any transfer of 
the Leased Premises to any affiliate of Landlord, Corporate Property 
Associates 12 Incorporated ("CPA 12") or Corporate Property Associates 14 
Incorporated ("CPA 14") or to any entity for whom W.P. Carey & Co., Inc., 
W.P. Carey Incorporated or any of their affiliates provides material 
management or investment advice, (vi) any Person to whom CPA 12 or CPA 14 
sell all or substantially all of their assets, (vii) any transfer of the 
Leased Premises to any of the successors or assigns of any of the Persons 
referred to in the foregoing clauses (i) through (vi) or (viii) any 
transfer, sale or conveyance of any part or all of the interests in 
Landlord between its members or to any affiliates of Landlord, CPA 12 or 
CPA 14.

        36.     Financing Major Alterations.

        (a)     Should Tenant, during the Term of this Lease, desire to make 
Alterations to any of the Leased Premises which are not readily removable 
without causing material damage to the Leased Premises which cannot be 
repaired and which will cost in excess of Five Hundred Thousand Dollars 
($500,000) ("Major Alterations"), Tenant may, prior to the commencement 
of construction of such Major Alterations, request Landlord (with a copy 
of such request to Lender) to reimburse the costs thereof to Landlord 
(the "Alteration Cost") to Tenant, to wit: cost of labor and materials, 
financing fees, legal fees, survey, title insurance and other normal and 
customary loan or construction costs.

        (b)     Should Landlord agree to reimburse such costs, Landlord and 
Tenant shall enter into good faith negotiations regarding the execution 
and delivery of a written agreement of modification of this Lease, which 
agreement shall provide for the following:

                (i)  payment by Landlord to Tenant of the Alteration 
Cost within one hundred twenty (120) days of the date of 
Landlord's agreement to pay the Alteration Cost, or in 
installment payments as agreed, or on the date of completion 
of the Major Alterations, whichever shall be the later;

                (ii)  an increase in the annual Basic Rent payable 
during the Amortization Period (as hereinafter defined) to an 
amount sufficient to amortize the Alteration Cost ("Total 
Financing") over a period (the "Amortization Period") which 
shall be the remainder of the then current Term and, if 
Tenant so elects, any additional extension periods provided 
for herein (so long as Tenant shall confirm any such 
extension periods included in the Amortization Period by a 
written waiver of its right to give notice of its intention 
not to renew this Lease prior to the expiration of such 
extension periods), at such rate of interest and upon such 
other terms as shall be agreed upon between Landlord and 
Tenant, but which shall be no less favorable than the 
prevailing interest rate and terms for unsecured loans in a 
principal amount equal to the Total Financings for borrowers 
with credit ratings equivalent to the lesser of Landlord's or 
Tenant's credit rating at that time; and

                (iii)  such other changes and amendments to this Lease 
as may be necessary and appropriate in view of such payment 
of the Alteration Cost by Landlord to Tenant.

        (c)     Tenant shall pay all Costs incurred by Landlord in connection 
with any such modification to this Lease and such financing, including 
closing costs, brokerage fees, taxes, recording charges and legal fees 
and expenses.

        (d)     If Landlord and Tenant do not reach agreement on Tenant's 
request to have Landlord finance the Alteration Costs, Tenant shall, 
subject to the provisions of Paragraph 13 of this Lease, have the right 
to construct the Major Alterations at Tenant's sole cost and expense.  In 
any event, the construction of the Major Alterations shall be performed 
in accordance with the provisions of Paragraph 13 hereof and the Major 
Alterations shall be the property of Landlord and part of the Leased 
Premises subject to this Lease.

        (e)     Nothing contained in this Paragraph 36 shall be construed to 
modify Paragraph 13 hereof, and the provisions of Paragraph 12 and 
subparagraphs (i) and (ii) of Paragraph 13(a) shall apply to all Major 
Alterations made or constructed hereunder, including the requirement for 
Landlord's consent to Alterations.

        37.     Security Deposit.

        (a)     Tenant has delivered to Landlord a security deposit (the 
"Security Deposit") in the amount of Three Hundred Forty-two Thousand 
Five Hundred Eighty-one and 25/100 ($342,581.25).  If not sooner applied 
as provided in Paragraph 23(e), the Security Deposit shall be applied 
(i) to monthly payments of the Basic Rent in reverse order, commencing 
with the last month of the Initial Term, commencing with the last payment 
due or (ii) if Tenant purchases the Leased Premises, against Tenant's 
obligation to pay the Default Termination Amount, Offer Amount or 
Termination Amount, as the case may be.  The Security Deposit shall be 
security for the payment by Tenant of the Rent and all other charges or 
payments to be paid hereunder and the performance of the covenants and 
obligations contained herein.  Landlord shall have the right to commingle 
the Security Deposit with other funds of Landlord.  Anything herein 
contained to the contrary notwithstanding, the Security Deposit shall be 
credited against Rent or other obligations of Tenant hereunder.

        (b)     Landlord shall have the right to assign to Lender or any 
other holder of a Mortgage the Security Deposit during the term of the 
applicable Loan, and the Lender or such other holder of a Mortgage shall 
have all of the rights of, and shall be subject to the terms of, this 
Paragraph 37.  Tenant covenants and agrees to execute such agreements, 
consents and acknowledgments as may be reasonably requested by Landlord 
and Lender from time to time to acknowledge the assignment of the 
Security Deposit.

        38.     Right to Vacate; Rejectable Offer Upon Vacation.

        (a)     Tenant shall have the right at any time after June 1, 2004 to 
vacate the Leased Premises; provided that (i) Tenant shall notify 
Landlord and Lender within ten (10) days after vacation of the Leased 
Premises by Tenant, (ii) Tenant shall make reasonable good faith efforts 
to sublet the Leased Premises, which sublease or subleases which shall be 
subject to the provisions of Paragraph 21(h) or (i) hereof, as the case 
may be, and (iii) Tenant shall continue to perform all of its obligations 
under this Lease, including its obligation to maintain the Leased 
Premises and to pay all Rent as and when due hereunder.

        (b)     If, at any time during the Term, the Leased Premises shall be 
vacant for twelve (12) consecutive months, Tenant shall, on the first day 
of the thirteenth (13th) month that Leased Premises are vacant, make an 
offer (the "Vacation Offer") to purchase the Leased Premises on the first 
Basic Rent Payment Date occurring thirty (30) days after the 
determination of Fair Market Value (the "Vacation Purchase Date") for a 
purchase price equal to the Offer Amount.  Promptly upon the delivery to 
Landlord of the Vacation Offer, Landlord and Tenant shall commence to 
determine the Fair Market Value of the Leased Premises.

        (c)     No rejection of the Vacation Offer shall be effective for any 
purpose unless consented to in writing by Lender.  If Landlord shall 
reject the Vacation Offer by notice to Tenant, containing the written 
consent of Lender to such rejection, no later than the thirtieth (30th) 
day following receipt of the Vacation Offer by Landlord, then this Lease 
shall remain in full force and effect and Landlord and Lender shall be 
deemed to have waived the Event of Default described in 
Paragraph 22(a)(x) with respect to a vacation of the Leased Premises.

        (d)     Unless Landlord shall have rejected the Vacation Offer by the 
foregoing notice to Tenant not later than the thirtieth (30th) day 
following receipt of the Vacation Offer by Landlord, Landlord shall be 
conclusively presumed to have accepted the Vacation Offer.  If the 
Vacation Offer is accepted by Landlord, then, through an appropriate 
escrow, (i) Tenant shall pay to Landlord the Offer Amount on the Vacation 
Purchase Date and, (ii) provided that no Rent or any other charge is due 
and unpaid under this Lease as of the Vacation Purchase Date and Tenant 
is otherwise in compliance with the terms hereof, Landlord shall convey 
to Tenant the Leased Premises in accordance with the provisions of 
Paragraph 20.

        39.     Miscellaneous.

Lease may be performed at any time and from time to time by Landlord or 
any person or entity designated by Landlord.  Each appointment of 
Landlord as attorney-in-fact for Tenant hereunder is irrevocable and 
coupled with an interest.  Except as otherwise specifically provided 
herein, Landlord shall have the right, at its sole option, to withhold or 
delay its consent whenever such consent is required under this Lease for 
any reason or no reason.  Time is of the essence with respect to the 
performance by Tenant of its obligations under this Lease.

drafter.

        (f)     This Lease may be modified, amended, discharged or waived 
only by an agreement in writing signed by the party against whom 
enforcement of any such modification, amendment, discharge or waiver is 
sought.

        (g)     The covenants of this Lease shall run with the land and bind 
Tenant, its successors and assigns and all present and subsequent 
encumbrances and subtenants of any of the Leased Premises, and shall 
inure to the benefit of Landlord, its successors and assigns.  If there 
is more than one Tenant, the obligations of each shall be joint and 
several.

        (h)     If any one or more of the provisions contained in this Lease

        (d)     For so long as an Event of Default has not occurred and is 
not continuing, on each Basic Rent Payment Date that occurs on or prior 
to, but not after June 1, 1999 and relates to any period occurring prior 
to June 1, 1999, Landlord shall approve as a portion of each advance of 
Project II Costs, the monthly installments of Basic Rent payable by 
Tenant under Paragraph 1(c)(i) and will credit each such advance against 
the installment of Basic Rent then due and owning, provided, however, 
that (i) from and after June 1, 1999, Landlord's obligation to make any 
further advance for future installments of Basic Rent shall terminate and 
all such future payments of Basic Rent shall be made by Tenant and (ii) 
during the continuation of an Event of Default Landlord shall have no 
obligation to make any further advances for installments of Basic Rent 
payable under Paragraph 1(c)(i), and Tenant shall make all further 
payments of Basic Rent from its own funds unless and until any such Event 
of Default is cured.

        2.      CPI Adjustments to Basic Rent.  The Basic Rent shall be 
subject to adjustment, in the manner hereinafter set forth, for increases 
in the index known as United States Department of Labor, Bureau of Labor 
Statistics, Consumer Price Index, All Urban Consumers, United States City 
Average, All Items, (1982-84=100) ("CPI") or the successor index that 
most closely approximates the CPI.  If the CPI shall be discontinued with 
no successor or comparable successor index, Landlord and Tenant shall 
attempt to agree upon a substitute index or formula, but if they are 
unable to so agree, then the matter shall be determined by arbitration in 
accordance with the rules of the American Arbitration Association then 
prevailing in New York City.  Any decision or award resulting from such 
arbitration shall be final and binding upon Landlord and Tenant and 
judgment thereon may be entered in any court of competent jurisdiction.  
In no event will the Basic Rent as adjusted by the CPI adjustment be less 
than the Basic Rent in effect immediately preceding such adjustment.  No 
CPI adjustments shall be made during any Renewal Term.

        4.      Effective Dates of CPI Adjustments.  (a) Basic Rent shall be 
adjusted on March 1, 1998 (the "First Basic Rent Adjustment Date") and on 
March 1, 2001 (the "Second Basic Rent Adjustment Date") to reflect 
changes in the CPI.  On the First Basic Rent Adjustment Date $1,030,452 
of Basic Rent shall be adjusted to reflect increases in the CPI during 
the three year period preceding March 1, 1998 and $574,428 of Basic Rent 
shall be adjusted to reflect increases in the CPI for the one year period 
preceding March 1, 1998.  On the Second Basic Rent Adjustment Date that 
portion of the Basic Rent described in Paragraph 1(a) and Paragraph 1(b) 
shall be adjusted to reflect changes in the CPI during the three year 
period preceding March 1, 2001 and that portion of the Basic Rent 
described in Paragraph 1(c)(ii) shall be adjusted to reflect changes in 
the CPI for the period from June 1, 1999 to and including March 1, 2001.

        (b)     After the Second Basic Rent Adjustment Date all Basic Rent 
shall be adjusted on March 1, 2004, March 1, 2007, March 1, 2010 and 
March 1, 2013 to reflect increases in the CPI during the most recent 
three (3) year period immediately preceding each of the foregoing dates 
in this subparagraph 3(b) (the First Basic Rent Adjustment Date, the 
Second Basic Rent Adjustment Date and each date referred to in this 
Subparagraph 3(b) being hereinafter referred to as the "Basic Rent 
Adjustment Date").

        5.      Method of Adjustment for CPI Adjustment.

        (a)     As of each Basic Rent Adjustment Date when the average CPI 
determined in clause (i) below exceeds the Beginning CPI (as defined in 
this Paragraph 4(a)), the Basic Rent (or portion thereof to be adjusted 
as specified in Paragraph 4) in effect immediately prior to the 
applicable Basic Rent Adjustment Date shall be multiplied by a fraction, 
the numerator of which shall be the difference between (i) the average 
CPI for the three (3) most recent calendar months (the "Prior Months") 
ending prior to such Basic Rent Adjustment Date for which the CPI has 
been published on or before the forty-fifth (45th) day preceding such 
Basic Rent Adjustment Date and (ii) the Beginning CPI, and the 
denominator of which shall be the Beginning CPI.  An amount equal to the 
lesser of (A) the product of such multiplication or (B) $145,960 with 
respect to the first Basic Rent Adjustment Date and the product of the 
Basic Rent (or portion thereof to be adjusted as specified in Paragraph 
4) in effect immediately prior to such Basic Rent Adjustment Date 
multiplied by 12% with respect to each succeeding Basic Rent Adjustment 
Date, shall be added to the Basic Rent (or portion thereof to be adjusted 
as specified in Paragraph 4) in effect immediately prior to such Basic 
Rent Adjustment Date.  As used herein, "Beginning CPI" shall mean the 
average CPI for the three (3) calendar months corresponding to the Prior 
Months, but occurring three (3) years earlier with respect to each 
adjustment of Basic Rent, except that (1) with respect to the $574,428 of 
Basic Rent to be adjusted on the First Basic Rent Adjustment Date, 
"Beginning CPI" shall mean the average CPI for the three (3) calendar 
months corresponding to the Prior Months but occurring one (1) year 
earlier and (2) with respect to the adjustment on March 1, 2001 of that 
portion of Basic Rent described in Paragraph 1(c)(ii) of this Exhibit "D" 
the "Beginning CPI" shall mean the average CPI for the three (3) calendar 
months occurring prior to June 1, 1999.  If the average CPI determined in 
clause (i) is the same or less than the Beginning CPI, the Basic Rent 
will remain the same for the ensuing three (3) year period.

        (b)     Effective as of a given Basic Rent Adjustment Date occurring 
during the Initial Term, Basic Rent payable under this Lease until the 
next succeeding Basic Rent Adjustment Date shall be the Basic Rent in 
effect after the adjustment provided for as of such Basic Rent Adjustment 
Date.

        (c)     Notice of the new annual Basic Rent shall be delivered to 
Tenant on or before the tenth (10th) day preceding each Basic Rent 
Adjustment Date.

        6.      Basic Rent During Each Renewal Term.  During each Renewal 
Term, annual Basic Rent for the Renewal Term shall be Fair Market Rental 
Value as of the first day of such Renewal Term, as determined in 
accordance with Paragraph 29 of the Lease.  Basic Rent during each 
Renewal Term shall be payable monthly in arrears in installments equal to 
1/12 of the annual Basic Rent for such Renewal Term.  If the Fair Market 
Rental Value of the Leased Premises has not been determined as of the 
first day of any Renewal Term, Tenant shall pay as monthly installments 
of Basic Rent an amount equal to the Basic Rent in effect immediately 
prior to such Renewal Date, and shall receive a credit or make an 
additional payment, as applicable, on the first Basic Rent Payment Date 
following the determination of Fair Market Rental Value.

goods or services, or otherwise) with respect to, any undertaking of any 
other Person (except as to any Subsidiary), or make or permit to exist

        (c)     Tenant will not, and will not permit any Subsidiary directly 
or indirectly to, incur, create, assume any Indebtedness other than (i)

the amount at any time of Fifteen Million Dollars ($15,000,000) in Funded 
Debt in addition to the Funded Debt described in (i) and (ii) above less
