("Landlord") and PCS HEALTH SYSTEMS, INC., a Delaware corporation, having its
principal office at 9501 E. Shea Boulevard, Scottsdale, AZ 85260 ("Tenant").


                  In consideration of the rents and provisions herein stipulated
to be paid and performed, Landlord and Tenant, intending to be legally bound,
hereby covenant and agree as follows:

1.      Demise of Premises. Landlord hereby demises and lets to Tenant and
Tenant hereby takes and leases from Landlord for the term and upon the
provisions hereinafter specified the following described property ("Leased
Premises"): (i) the lot or parcel of land described in Exhibit "A" attached
hereto and made a part hereof, together with the easements, rights and
appurtenances thereunto belonging or appertaining ("Land"); (ii) the buildings,
structures and other improvements on the Land (collectively, the
"Improvements"); and (iii) the machinery and equipment which is attached to the
Improvements in such a manner as to become fixtures under applicable law,
together with all additions and accessions thereto, substitutions therefor and
replacements thereof permitted by this Lease (collectively, the "Equipment").

                  The Leased Premises includes as a right and appurtenance
thereto the easement for access and parking over certain land on property
adjacent to the Land (the "Easement"), as more particularly described in that
certain Easement Agreement dated July 10, 2000 and recorded at Docket Number
2000-0538396 in the Records of Maricopa County, Arizona (the "Easement
Agreement"), the adjacent property being therein defined as the "Existing
Parking Field." The Grantor under the Easement Agreement has the right to
substitute for the Existing Parking Field a different parcel of its land (the
"Substitute Parking Field" as defined in the Easement Agreement), in which event
the Easement Agreement will be terminated and fee simple title of the Substitute
Parking Field will be conveyed to the owner of the Land. At such time as the
Easement Agreement is terminated and the Substitute Parking Field is conveyed to
the owner of the Land, this Lease shall be deemed to be automatically amended to
provide (i) the Leased Premises will not include the Easement over the Existing
Parking Field and all rights of Tenant to the Easement are terminated and (ii)
provided this Lease is then in full force and effect, the Leased Premises
includes the Substitute Parking Field.

ANY OF THE LEASED PREMISES, AND LANDLORD LEASES AND WILL LEASE AND TENANT TAKES
AND) WILL TAKE THE LEASED PREMISES "AS IS", AND TENANT ACKNOWLEDGES THAT

OR REPRESENTATION, EXPRESS OR IMPLIED, WITH RESPECT TO ANY OF THE LEASED

<PAGE>   9


satisfactory to it. In the event of any defect or deficiency in any of the
Leased Premises of any nature, whether patent or latent, Landlord shall not have
any responsibility or liability with respect thereto or for any incidental or
consequential damages (including strict liability in tort). The provisions of
this Paragraph 3(b) have been negotiated, and the foregoing provisions are
intended to be a complete exclusion and negation of any warranties by Landlord,
express or implied, with respect to any of the Leased Premises, arising pursuant
to the uniform commercial code or any other Law now or hereafter in effect or
otherwise.

                  (c) Tenant acknowledges and agrees that Tenant has examined
the title to the Leased Premises prior to the execution and delivery of this
Lease and has found such title to be satisfactory for the purposes contemplated
by this Lease.

                  (d) Landlord hereby assigns, without recourse or warranty
whatsoever, to Tenant, all warranties, guaranties and indemnities, express or
implied, and similar rights which Landlord may have against any manufacturer,
seller, engineer, contractor or builder in respect of any of the Leased
Premises, including, but not limited to, any rights and remedies existing under
contract or pursuant to the uniform commercial code (collectively, the
"guaranties"). Such assignment shall remain in effect until the termination of
this Lease. Landlord shall also retain the right to enforce any guaranties
assigned in the name of Tenant upon the occurrence of an Event of Default.
Landlord hereby agrees to execute and deliver at Tenant's expense such further
documents, including powers of attorney, as Tenant may reasonably request in
order that Tenant may have the full benefit of the assignment effected or
intended to be effected by this Paragraph 3(d). Upon the termination of this
Lease, the guaranties shall automatically revert to Landlord. The foregoing
provision of reversion shall be self-operative and no further instrument of
reassignment shall be required. In confirmation of such reassignment Tenant
shall execute and deliver promptly any certificate or other instrument which
Landlord may reasonably request. Any monies collected by Tenant under any of the
guaranties after the occurrence of and during the continuation of an Event of
Default shall be held in trust by Tenant and promptly paid over to Landlord.

                  (e) Landlord agrees to enter into, at Tenant's expense, such
easements, covenants, waivers, approvals or restrictions for utilities, parking
or other matters as desirable for operation of the Leased Premises or properties
adjacent thereto (collectively, "Easements") as reasonably requested by Tenant,
subject to Lender's and Landlord's approval of the form thereof, not to be
unreasonably withheld or delayed; provided, however, that no such Easement shall
result in any diminution in the value or utility of the Leased Premises and
further provided that no such Easement shall render the use of the Leased
Premises dependent upon any other property or condition the use of the Leased
Premises upon the use of any other property, each of which Tenant shall certify
to Landlord and Lender in writing delivered with Tenant's request with respect
to such Easement. Tenant's request shall also include Tenant's written
undertaking acknowledging that Tenant shall remain liable hereunder as principal
and not merely as a surety or guarantor notwithstanding the establishment of any
Easement. If either Landlord or Lender shall fail to approve or disapprove the
form of any such Easements, within a period of thirty (30)


                                       6
<PAGE>   10


days from their respective receipt of same, then either Landlord or Lender, as
the case may be, shall be deemed to have approved the form of any such Easement.

                  (f) Tenant agrees that Tenant is obligated to and shall
perform all obligations of the owner of the Leased Premises under and pay all
expenses which the owner of the Leased Premises may be required to pay in
accordance with any reciprocal easement agreement or any other agreement or
document of record now, or of record in the future if created or filed by or
with the consent of Tenant, affecting the Leased Premises, herein referred to
collectively as the "REA", and that Tenant shall comply with all of the terms
and conditions of the REA during the Term of this Lease. Tenant further
covenants and agrees to indemnify, defend and hold harmless Landlord and Lender
against any claim, loss or damage suffered by Landlord or Lender by reason of
Tenant's failure to perform any obligations or pay any expenses as required
under any REA or comply with the terms and conditions of any REA as herein above
provided during the Term of this Lease.

4.      Use of Leased Premises; Quiet Enjoyment.

                  (a) Tenant may use the Leased Premises for an office building
with associated uses such as, by way of example and not by way of limitation, a
cafeteria and workout room, and any other lawful purpose so long as such other
lawful purpose would not (i) have a material adverse effect on the value of the
Leased Premises, (ii) materially increase the likelihood that Tenant, Landlord
or Lender would incur liability under any provisions of the Act referred to in
Paragraph 26 of this Lease, or (iii) result in or give rise to any material
environmental deterioration or degradation of the Leased Premises. In no event
shall the Leased Premises be used for any purpose which shall violate any of the
provisions of any Permitted Encumbrance or any covenants, restrictions or
agreements hereafter created by or consented to by Tenant applicable to the
Leased Premises. Tenant agrees that with respect to the Permitted Encumbrances
and any covenants, restrictions or agreements hereafter created by or consented
to by Tenant, Tenant shall observe, perform and comply with and carry out the
provisions thereof required therein to be observed and performed by Landlord.

                  (b) Subject to Tenant's rights under Paragraph 18 hereof,
Tenant shall not permit any unlawful occupation, business or trade to be
conducted on the Leased Premises or any use to be made thereof contrary to
applicable Legal Requirements or Insurance Requirements. Subject to Tenant's
rights under Paragraph 18, Tenant shall not use, occupy or permit any of the
Leased Premises to be used or occupied, nor do or permit anything to be done in
or on any of the Leased Premises, in a manner which would (i) make void or
voidable any insurance which Tenant is required hereunder to maintain then in
force with respect to any of the Leased Premises, (ii) affect the ability of
Tenant to obtain any insurance which Tenant is required to furnish hereunder, or
(iii) cause any injury or damage to any of the Improvements unless pursuant to
Alterations permitted under Paragraph 12 hereof.

                  (c) Subject to all of the provisions of this Lease, so long as
no Event of Default exists hereunder, Landlord covenants that Tenant will have
the peaceful and quiet occupation and enjoyment of the Leased Premises.

5.      Term.

                  (a) Subject to the provisions hereof Tenant shall have and
hold the Leased Premises for an initial term (the "Initial Term") commencing on
the effective date hereof (the "Commencement Date") and ending on that date
which is the last calendar day prior to the twenty-first anniversary of the
Commencement Date (the "Expiration Date") (the period of time from the
Commencement Date through and including the Expiration Date, as same may be
extended by any Renewal Term, hereinafter called the "Term").

                  (b) Provided that if, on or prior to the Expiration Date or
any other Renewal Date (as hereinafter defined) this Lease shall not have been
terminated pursuant to any provision hereof, then on the Expiration Date and on
the fifth (5th), tenth (10th), fifteenth (15th), twentieth (20th) and
twenty-fifth (25th) anniversaries of the Expiration Date (the Expiration Date
and each such anniversary being a "Renewal Date"), the Term shall be deemed to
have been automatically extended for an additional period of five (5)years (each
such extension, a "Renewal Term"), unless Tenant shall notify Landlord in
writing in recordable form at least eighteen (18) months prior to the next
Renewal Date that Tenant is terminating this Lease as of the next Renewal Date.
Any such extension of the Term shall be subject to all of the provisions of this
Lease, as the same may be amended, supplemented or modified.

                  (c) If Tenant exercises its option not to extend or further
extend the Term, or if an Event of Default occurs, then Landlord shall have the
right during the remainder of the Term then in effect and, in any event,
Landlord shall have the right during the last year of the Term, to (i) advertise
the availability of the Leased Premises for sale or reletting and to erect upon
the Leased Premises signs indicating such availability and (ii) show the Leased
Premises to prospective purchasers or tenants or their agents at such reasonable
times as Landlord may select.

6.      Rent.

                  (a) Tenant shall pay to Landlord (or to Lender, if directed by
Landlord), as minimum annual rent for the Leased Premises (i) during each year
of the Initial Term, the sum of Four Million Three Hundred Thousand Dollars
($4,300,000), payable in equal monthly installments of $358,333.33 each ("Basic
Rent"), in arrears, commencing on the first day of the month following the month
in which the Commencement Date occurs and continuing on the first day of each
month thereafter during the Initial Term and (ii) during each year of each
Renewal Term in the annual sum determined in accordance with subparagraph 6(b)
below, in equal monthly installments, in each case for the preceding month, and
on the last day of the Term for the month then ending (said days being called
the "Basic Rent Payment Dates"), and shall pay


                                       8
<PAGE>   12


the same at Landlord's address set forth below, or at such other place as
Landlord from time to time may designate to Tenant in writing, in funds which at
the time of such payment shall be legal tender for the payment of public or
private debts in the United States of America and if required by Lender by wire
transfer in immediately available federal funds to such account in such bank as
Lender shall designate, from time to time. If the Commencement Date is not the
first day of a calendar month, Basic Rent for the period from and including the
Commencement Date through and including the last day of the month in which the
Commencement Date occurs shall be paid, in arrears, in an amount equal to one
thirtieth (1/30) of the monthly installment of Basic Rent for each day from and
including the Commencement Date through and including the last day of the month
in which the Commencement Date occurs.


                  (b) During each Renewal Term, Basic Rent for the entire
Renewal Term shall be an amount equal to the greater of (x) ninety-five percent
(95%) of the Fair Market Rental Value as of the first day of the applicable
Renewal Term as determined in accordance with the provisions of Exhibit B and
(y) the Basic Rent in effect for the twelve (12) month period immediately
preceding the applicable Renewal Term.

                  (c) Tenant shall pay and discharge before the imposition of
any fine, lien, interest or penalty may be added thereto for late payment
thereof, as Additional Rent, all other amounts and obligations which Tenant
assumes or agrees to pay or discharge pursuant to this Lease, together with
every fine, penalty, interest and cost which may be added by the party to whom
such payment is due for nonpayment or late payment thereof. In the event of any
failure by Tenant to pay or discharge any of the foregoing, Landlord shall have
all rights, powers and remedies provided herein, by Law or otherwise, in the
event of nonpayment of Basic Rent.

                  (d) If any installment of Basic Rent is not paid within five
(5) days after written notice is given by Landlord or Lender (or Lender's
servicer or other designee of Lender) to Tenant that the same is overdue, Tenant
shall pay to Landlord or Lender, as the case may be, on demand, as Additional
Rent, a late charge equal to three percent (3%) (the "Late Charge") on such
overdue installment of Basic Rent.

                  (e) Landlord and Tenant agree that this Lease is a true lease
and does not represent a financing arrangement. Each party shall reflect the
transactions represented by this Lease in all applicable books, records and
reports (including, without limitation, income tax filings) in a manner
consistent with "true lease" treatment rather than "financing" treatment.

7.      Net Lease: Non-Terminability.

                  (a) This is a net Lease and Basic Rent, Additional Rent and
all other sums payable hereunder by Tenant shall be paid, except as otherwise
expressly set forth in this Lease, without notice, demand, setoff, counterclaim,
recoupment, abatement, suspension, deferment, diminution, deduction, reduction
or defense.


                                       9
<PAGE>   13


                  (b) Except as otherwise expressly provided in this Lease, this
Lease shall not terminate and Tenant shall not have any right to terminate this
Lease, during the Term. Except as otherwise expressly provided in this Lease,
Tenant shall not be entitled to any setoff, counterclaim, recoupment, abatement,
suspension, deferment, diminution, deduction, reduction or defense of or to
Basic Rent, Additional Rent or any other sums payable under this Lease; and
except as otherwise expressly provided in this Lease, the obligations of Tenant
under this Lease shall not be affected by any interference with Tenant's use of
any of the Leased Premises for any reason, including but not limited to the
following: (i) any damage to or destruction of any of the Leased Premises by any
cause whatsoever, (ii) any Condemnation, (iii) the prohibition, limitation or
restriction of Tenant's use of any of the Leased Premises, (iv) any eviction by
paramount title or otherwise, (v) Tenant's acquisition of ownership of any of
the Leased Premises other than pursuant to an express provision of this Lease,
(vi) any default on the part of Landlord under this Lease or under any other
agreement, (vii) any latent or other defect in, or any theft or loss of any of
the Leased Premises, (viii) the breach of any warranty of any seller or
manufacturer of any of the Equipment, (ix) any violation of Paragraph 4(c) by
Landlord, or (x) any other cause, whether similar or dissimilar to the
foregoing, any present or future Law to the contrary notwithstanding. It is the
intention of the parties hereto that the obligations of Tenant under this Lease
shall be separate and independent covenants and agreements, and that Basic Rent,
Additional Rent and all other sums payable by Tenant hereunder shall continue to
be payable in all events (or, in lieu thereof, Tenant shall pay amounts equal
thereto), and that the obligations of Tenant under this Lease shall continue
unaffected, unless this Lease shall have been terminated pursuant to an express
provision of this Lease.

                  (c) Tenant agrees that it shall remain obligated under this
Lease in accordance with its provisions and that, except as otherwise expressly
provided herein, it shall not take any action to terminate, rescind or avoid
this Lease, notwithstanding (i) the bankruptcy, insolvency, reorganization,
composition, readjustment, liquidation, dissolution, winding-up or other
proceeding affecting Landlord, (ii) the exercise of any remedy, including
foreclosure, under the Mortgage, or (iii) any action with respect to this Lease
(including the disaffirmance hereof) which may be taken by Landlord under the
Federal Bankruptcy Code or by any trustee, receiver or liquidator of Landlord or
by any court under the Federal Bankruptcy Code or otherwise.

                  (d) This Lease is the absolute and unconditional obligation of
Tenant. Tenant waives all rights which are not expressly stated in this Lease
but which may now or hereafter otherwise be conferred by Law (i) to quit,
terminate or surrender this Lease or any of the Leased Premises, (ii) to any
setoff, counterclaim, recoupment, abatement, suspension, deferment, diminution,
deduction, reduction or defense of or to Basic Rent, Additional Rent or any
other sums payable under this Lease, except as otherwise expressly provided in
this Lease, and (iii) for any statutory lien or offset right against Landlord or
its property.

8.      Payment of Impositions: Compliance with
                Legal Requirements and Insurance Requirements.

                  (a)      (i) Subject to the provisions of Paragraph 18 hereof
relating to contests, Tenant shall, before interest or penalties are due
thereon, pay and discharge (all of the following being herein collectively
called the "Impositions"): all taxes of every kind and nature (including real,
ad valorem, personal property, gross income, franchise, withholding, profits and
gross receipts taxes) on or with respect to the Leased Premises; all charges
and/or taxes for any easement or agreement maintained for the benefit of the
Leased Premises; all general and special assessments, levies, permits,
inspection and license fees on or with respect to the Leased Premises; all water
and sewer rents and other utility charges on or with respect to the Leased
Premises; all ground rents on or with respect to the Leased Premises; and all
other public charges and/or taxes whether of a like or different nature, even if
unforeseen or extraordinary, imposed or assessed upon or with respect to the
Leased Premises, during the Term, against Landlord, Tenant or any of the Leased
Premises as a result of or arising in respect of the occupancy, leasing, use,
maintenance, operation, management, repair or possession thereof, or any
activity conducted on the Leased Premises, or the Basic Rent or Additional Rent,
including without limitation, any gross income tax, sales tax, occupancy tax or
excise tax levied by any governmental body on or with respect to such Basic Rent
or Additional Rent. If received by Landlord, Landlord shall promptly deliver to
Tenant any bill or invoice with respect to any Imposition.

                           (ii) Nothing herein shall obligate Tenant to pay, and
the term "Impositions" shall exclude, federal, state or local (A) transfer taxes
as the result of a conveyance by (or suffered by) Landlord, (B) franchise,
capital stock or similar taxes if any, of Landlord, (C) income, excess profits
or other taxes, if any, of Landlord, determined on the basis of or measured by
its net income, or (D) any estate, inheritance, succession, gift, capital levy
or similar taxes, unless the taxes referred to in clauses (B) and (C) above are
in lieu of or a substitute for any other tax or assessment upon or with respect
to any of the Leased Premises which, if such other tax or assessment were in
effect at the commencement of the Term, would be payable by Tenant. In the event
that any assessment against any of the Leased Premises may be paid in
installments, Tenant shall have the option to pay such assessment in
installments; and in such event, Tenant shall be liable only for those
installments which 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 and to Lender, within twenty
(20) days after Landlord's written request therefor, copies of all settlements
and notices pertaining to the Impositions which may be issued by any
governmental authority and receipts for payments of all Impositions made during
each calendar year of the Term, within thirty (30) days after payment.

                           (iii) Landlord and Tenant acknowledge that as of the
Commencement Date of this Lease Landlord will not require Tenant to pay to
Landlord an additional monthly sum (an "Escrow Payment") sufficient to pay
Escrow Charges (as hereinafter defined) as they become due. However, Tenant
acknowledges that, from and after the date that a Mortgage shall be in effect
Landlord shall have the right to require Tenant to pay to Landlord an Escrow
Payment sufficient to pay the Escrow Charges (as hereinafter defined) as they
become due, if and to the extent required by the Lender. As used herein, "Escrow
Charges" shall mean real estate taxes on the Leased Premises or payments in lieu
thereof and premiums on any


                                       11
<PAGE>   15


insurance required to be maintained by Tenant under this Lease and any reserves
for capital improvements, deferred maintenance or required repairs or
replacements required by any Lender. Landlord and Lender, shall determine the
amount of the Escrow Charges and of each Escrow Payment in good faith and
consistent with amounts required by similar lenders for properties similar to
the Leased Premises as to location, use, size and condition. As long as the
Escrow Payments are being held by Landlord the Escrow Payments shall not be
commingled with other funds of Landlord or other Persons and interest thereon
shall accrue for the benefit of Tenant from the date such monies are received
and invested until the date such monies are disbursed to pay Escrow Charges.
Landlord 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 shall be insufficient
for the payment of the Escrow Charges, Tenant, within ten (10) days after
Landlord's demand therefor, shall pay the amount of the deficiency to Landlord

                  (b) Subject to the provisions of Paragraph 18 hereof, Tenant
shall promptly comply with and conform to all of the Legal Requirements and
Insurance Requirements.

9.      Liens; Recording and Title.

                  (a) Subject to the provisions of Paragraph 18 hereof, Tenant
shall not, directly or indirectly, create or permit to be created or to remain,
and shall promptly discharge, any lien on the Leased Premises, on the Basic
Rent, Additional Rent or on any other sums payable by Tenant under this Lease,
other than the Mortgage, the Permitted Encumbrances and any mortgage, lien,
encumbrance or other charge created by or resulting from any act or omission by
Landlord or those claiming by, through or under Landlord (except Tenant).
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 any of
the Leased Premises through or under Tenant, and that no mechanic's 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.

                  (b) Each of Landlord and Tenant shall execute, acknowledge and
deliver to the other a written Memorandum of this Lease to be recorded in the
appropriate land records of the jurisdiction in which the Leased Premises is
located, in order to give public notice and protect the validity of this Lease.
In the event of any discrepancy between the provisions of said recorded
Memorandum of this Lease and the provisions of this Lease, the provisions of
this Lease shall prevail.

                  (c) Nothing in this Lease and no action or inaction by
Landlord shall be deemed or construed to mean that Landlord has granted to
Tenant any right, power or permission to do any act or to make any agreement
which may create, give rise to, or be the foundation for, any right, title,
interest or lien in or upon the estate of Landlord in any of the Leased
Premises.

10.     Indemnification.

                  (a) Tenant agrees to defend, pay, protect, indemnify, save and
hold harmless Landlord and Lender, and their officers, directors, shareholders,
partners, beneficial owners, trustees, members, managers and employees, from and
against any and all liabilities, losses, damages, penalties, costs, expenses
(including reasonable attorneys' fees and expenses), causes of action, suits,
claims, demands or judgments of any nature whatsoever, howsoever caused, arising
from the Leased Premises or the use, non-use, occupancy, condition, design,
construction, maintenance, repair or rebuilding of the Leased Premises, and any
injury to or death of any person or persons or any loss of or damage to any
property, real or personal, in any manner arising therefrom connected therewith
or occurring thereon, whether or not such indemnified party has or should have
knowledge or notice of the defect or conditions, if any, causing or contributing
to said injury, death, loss, damage or other claim; except to the extent that
any such liability, loss, damage, penalty, cost, expense, cause of action, suit,
claim, demand or judgment is the result of the gross negligence of such
indemnified party or the intentional wrongful act of such indemnified party. In
case any action or proceeding is brought against any indemnified party by reason
of any such claim against which Tenant has agreed to defend, pay, protect,
indemnify, save and hold harmless pursuant to the preceding sentence, Tenant
covenants upon notice from such indemnified party to resist or defend such
indemnified party in such action, with the expenses of such defense paid by
Tenant, and such indemnified party will cooperate and assist in the defense of
such action or proceeding if reasonably requested so to do by Tenant.

                  (b) The obligations of Tenant under this Paragraph 10 shall
survive any termination of this Lease.

11.     Maintenance and Repair.

                  (a) Except for any Alterations that Tenant is permitted to
make pursuant to this Lease, Tenant shall at all times, including any
Requisition period, put, keep and maintain the Leased Premises (including,
without limitation, the roof, landscaping, walls, footings, foundations and
structural components of the Leased Premises) and the Equipment in the same
condition and order of repair as exists as of the date of this Lease, ordinary
wear and tear excepted, and shall promptly make all repairs and replacements of
every kind and nature, whether foreseen or unforeseen, which may be required to
be made upon or in connection with the Leased Premises in order to keep and
maintain the Leased Premises in the order and condition required by this
Paragraph 11(a). Tenant shall do or cause others to do all shoring of the Leased
Premises or of foundations and walls of the Improvements and every other act
necessary or appropriate for preservation and safety thereof, by reason of or in
connection with any excavation or other building operation upon any of the
Leased Premises, whether or not Landlord shall, by reason of any Legal
Requirements or Insurance Requirements, be required to take such action or be
liable for failure to do so. Landlord shall not be required to make any


                                       13
<PAGE>   17


repair, whether foreseen or unforeseen, or to maintain any of the Leased
Premises or Adjoining Property in any way, and Tenant hereby expressly waives
the right to make repairs at the expense of the Landlord, which right may be
provided for in any Law now or hereafter in effect. Nothing in the preceding
sentence shall be deemed to preclude Tenant from being entitled to insurance
proceeds or condemnation awards for Restoration pursuant to Paragraphs 13 (c)
and 14 (g) of this Lease. Tenant shall, in all events, make all repairs for
which it is responsible hereunder promptly, and all repairs shall be in a good,
proper and workmanlike manner. In the event of any casualty or other destruction
of any portion of the Leased Premises, this Lease shall continue with no off-set
or abatement of any monetary obligation of Tenant hereunder. Furthermore,
promptly after any casualty to or other destruction of the Leased Premises,
Tenant shall commence and diligently continue to restore the Leased Premises
(including the Equipment) pursuant to Paragraphs 14(g) and 15 to substantially
the same size, layout, utility, value, condition and character as existed
immediately prior to such event (assuming the Leased Premises to have been in
the condition required by this Lease) and otherwise as required under this Lease
without regard to whether any insurance proceeds are made available to Tenant.

                  (b) In the event that any Improvement shall violate any Legal
Requirements or Insurance Requirements and as a result of such violation
enforcement action is threatened or commenced against Tenant or with respect to
the Leased Premises, then Tenant, at the request of Landlord, shall either (i)
obtain valid and effective waivers or settlements of all claims, liabilities and
damages resulting from each such violation, whether the same shall affect
Landlord, Tenant or both, or (ii) take such action as shall be necessary to
remove such violation, including, if necessary, any Alteration. Any such repair
or Alteration shall be made in conformity with the provisions of Paragraph 12.

                  (c) If Tenant shall be in default under any of the provisions
of this Paragraph 11 or Paragraph 26, Landlord may after thirty (30) business
days written notice given to Tenant and failure of Tenant to cure during said
period, but without notice in the event of an emergency, do whatever is
necessary to cure such default as may be appropriate under the circumstances
for the account of and at the expense of Tenant. In the event of an emergency
Landlord shall notify Tenant of the situation by phone or other available
communication. All reasonable sums so paid by Landlord and all reasonable costs
and expenses (including, without limitation, attorneys' fees and expenses) so
incurred, together with interest thereon at the Default Rate from the date of
payment or incurring the expense, shall constitute Additional Rent payable by
Tenant under this Lease and shall be paid by Tenant to Landlord on demand.

                  (d) Tenant shall from time to time replace with other
operational equipment or parts (the "Replacement Equipment") any of the
Equipment (the "Replaced Equipment") which shall have become worn out or
unusable for the purpose for which it is intended, been taken by a Condemnation
as provided in Paragraph 13, or been lost, stolen, damaged or destroyed as
provided in Paragraph 14. Tenant shall repair at its sole cost and expense all
damage to the Leased Premises caused by the removal of Equipment or Replaced
Equipment or other personal property of Tenant or the installation of
Replacement Equipment.


                                       14
<PAGE>   18


All Replacement Equipment shall become the property of Landlord, shall be free
and clear of all liens and rights of others and shall become a part of the
Equipment as if originally demised herein.

12.     Alterations.

                  (a) Tenant shall not make any Alterations which would (after
the completion thereof) impair the structural integrity of the Leased Premises,
without Landlord's written consent, which consent Landlord agrees not
unreasonably to withhold or delay. Tenant may make any other Alterations without
the prior written consent of the Landlord provided such Alterations comply with
all of the provisions of the following sentence.

                  (b) In the event that Landlord gives its prior written consent
to any Alterations, or if such consent is not required, Tenant agrees that in
connection with any Alteration: (i) the fair market value of the Leased Premises
shall not be lessened in any material respect after the completion of any such
Alteration, or its structural integrity impaired; (ii) the Alteration and any
Alteration theretofore made or thereafter to be made shall not in the aggregate
reduce the gross floor area of the Improvements by more than ten percent (10%);
(iii) all such Alterations shall be performed in a good and workmanlike manner,
and shall be expeditiously completed in compliance with all Legal Requirements;
(iv) all work done in connection with any such Alteration shall comply with all
Insurance Requirements; (v) Tenant shall promptly pay all costs and expenses of
any such Alteration, and shall (subject to the provisions of Paragraph 18
hereof) discharge all liens filed against any of the Leased Premises arising
out of the same; (vi) Tenant shall procure and pay for all permits and licenses
required in connection with any such Alteration; (vii) all such Alterations
shall be the property of Landlord and shall be subject to this Lease; and (viii)
all Alterations shall be made in the case of any Alteration the estimated cost
of which in any one instance exceeds One Million Dollars ($1,000,000) under the
supervision of an architect or engineer and, in accordance with plans and
specifications which shall be submitted to Landlord (for informational purposes
only) prior to the commencement of the Alterations.

13.     Condemnation.

                  (a) Tenant, promptly after obtaining knowledge of the
institution of any proceeding for Condemnation, shall notify Landlord thereof
and Landlord shall be entitled to participate in any Condemnation proceeding.
Landlord, promptly after obtaining knowledge of the institution of any
proceeding for Condemnation, shall notify Tenant thereof and Tenant shall have
the right to participate in such proceedings. Subject to the provisions of this
Paragraph 13 and Paragraph 15, Tenant hereby irrevocably assigns to Lender or to
Landlord, in that order, any award or payment in respect of any Condemnation of
Landlord's interest in the Leased Premises, except that (except as hereinafter
provided) nothing in this Lease shall be deemed to assign to Landlord or Lender
any award relating to the value of the leasehold interest created by this Lease
or any award or payment on account of the Trade Fixtures, moving expenses and
out-of-pocket


                                       15
<PAGE>   19


expenses incidental to the move, if available, to the extent Tenant shall have a
right to make a separate claim therefor against the condemnor, it being agreed,
however, that Tenant shall in no event be entitled to any payment that reduces
the award to which Landlord is or would be entitled for the condemnation of
Landlord's interest in the Leased Premises. Notwithstanding the foregoing,
Tenant shall be entitled to any award or payment on account of Tenant's
leasehold interest under this Lease only in the event of a Condemnation
described in Paragraph 13(b)(i)(A) and then only to the extent that when such
award, added to all other awards to which Tenant is entitled hereunder, is
subtracted from the entire award in respect to all interests in the Leased
Premises, the remainder exceeds the amount set forth on Exhibit "D" attached
hereto and made a part hereof.

                  (b) (i) (A) If (I) the entire Leased Premises or (II) at
least ten percent (10%) of the applicable Land or the building constructed on
the Land or any means of ingress, egress or access to the Leased Premises, the
loss of which even after Restoration would, in Tenant's reasonable business
judgment, be substantially and materially adverse to the business operations of
Tenant at the Leased Premises, shall be subject of a Taking by a duly
constituted authority or agency having jurisdiction, then Tenant shall, not
later than ninety (90) days after a Taking has occurred, serve notice ("Tenant's
Termination Notice") upon Landlord of Tenant's intention to terminate this Lease
on any Basic Rent Payment Date specified in such Tenant's Termination Notice,
which date (the "Termination Date") shall be no sooner than the first Basic Rent
Payment Date occurring at least thirty (30) days after the date of such Tenant's
Termination Notice. Notwithstanding the foregoing, in the event of a Taking
affecting the Land only, then, so long as (i) there remains any viable means of
access, ingress and egress to the Leased Premises (before or after restoration),
(ii) there remains sufficient parking area to meet minimum parking requirements
under applicable law and (iii) the Leased Premises are otherwise restorable so
as to comply with applicable zoning requirements, such a Taking shall not be
deemed to be substantially and materially adverse to the business operations of
Tenant at the Leased Premises.

                           (B) In the event that during the period covered by
the schedule of purchase prices attached hereto as Exhibit "C," Tenant shall
serve a Tenant's Termination Notice upon Landlord, Tenant shall, as part of such
Tenant's Termination Notice offer (which offer may be rejected by Landlord as
set forth below) to purchase the Leased Premises and the award (or if no part of
the Leased Premises shall remain, the entire award) for the applicable price
(the "Purchase Price") computed in accordance with the schedule annexed hereto
and marked Exhibit "C" plus all other amounts which may be due and owing to
Lender or Landlord by reason of any default by Tenant in complying with its
obligations under this Lease (the "Additions to Purchase Price").

                           (C) If Landlord and Lender shall not elect to accept
Tenant's offer to purchase, Landlord shall give notice thereof to Tenant within
thirty (30) days after the giving of Tenant's Termination Notice.

<PAGE>   20
                                    (D) Should an offer to purchase not be
accepted by Landlord and Lender, this Lease shall be terminated as above
provided and the entire award made in the Condemnation proceeding with respect
to the Leased Premises shall be paid to Lender or to Landlord in that order.

                                    (E) Landlord's notice not to accept Tenant's
offer to purchase shall be void and of no effect unless accompanied by the
written notice of Lender to the effect that Lender also elects not to accept
Tenant's offer to purchase. Should said notices of Landlord and Lender rejecting
Tenant's offer to purchase not be served within said period of thirty (30) days,
then and in that event, the said offer shall be deemed accepted.

                                    (ii) In the event that Landlord and Lender
shall accept or be deemed to have accepted Tenant's offer to purchase title
shall close and Purchase Price and Additions to Purchase Price shall be paid as
hereinafter provided and in such event Tenant shall be entitled to and shall
receive any and all awards with respect to the Leased Premises then or
thereafter made in the Condemnation proceeding and Landlord shall assign (or in
case of any award previously made, deliver to Tenant on the Closing Date) such
award as may be made with respect to the Leased Premises. In the event Landlord
and Lender shall accept Tenant's offer to purchase with respect to the Leased
Premises, or be deemed to have accepted such Tenant's offer, title shall close
thirty (30) days after the Termination Date hereinbefore defined (the "Closing
Date"), at noon at the local office of Landlord's counsel, or at such other time
and place as the parties hereto may agree upon, this Lease shall be
automatically extended to and including the Closing Date (or, if applicable the
extended Closing Date hereinafter described) and Tenant shall pay the Purchase
Price and Additions to Purchase Price by transferring immediate funds to such
account or accounts and in such bank or banks as Lender or Landlord, in that
order, shall designate, upon delivery of a special warranty deed (or local
equivalent) conveying Leased Premises and all other required documents including
an assignment of any award in connection with the taking of Leased Premises. The
special warranty deed (or local equivalent) shall convey title, free from
encumbrances other than (A) Permitted Encumbrances, (B) liens or encumbrances
created, suffered or consented to in writing by Tenant or arising by reason of
the failure of Tenant to observe or perform any of the terms, covenants or
agreements herein provided to be observed and performed by Tenant, (C) any
installments of Impositions then affecting the Leased Premises, and (D) this
Lease. The Purchase Price and Additions to Purchase Price payable as herein
above provided shall be charged or credited, as the case may be, on the Closing
Date, to reflect adjustments of Basic Rent paid or payable to and including the
Closing Date, apportioned as of the Closing Date. Tenant shall pay all
conveyance, transfer, sales and like taxes required in connection with the
purchase, regardless of who is required to pay such taxes under State or local
Law or custom (and Tenant shall also pay to Landlord any amount necessary to
yield to Landlord the entire Purchase Price and Additions to Purchase Price if
as a matter of the Law of the State or locality such tax cannot be paid directly
by Tenant). If there be any liens or encumbrances against the Leased Premises
which Landlord is obligated to remove, upon request made a reasonable time
before the Closing Date, Landlord shall provide at the Closing separate funds
for the foregoing, payable to the holder of such lien or encumbrances.

                            (c)     (i) In the event of a Condemnation of any
part of the Leased Premises which does not result in a Termination of this
Lease, subject to the requirements of Paragraph 15, the Net Award of such
Condemnation shall be retained by Landlord; and promptly after such
Condemnation, Tenant shall commence and diligently continue to restore the
Leased Premises as nearly as possible to its value, condition and character
immediately prior to such Condemnation, in accordance with the provisions of
this Lease, including but not limited to the provisions of Paragraphs 11(a), 12
and 15 (such restoration following a Condemnation and restoration following a
casualty is, as the context shall require, herein called a "Restoration").

                                    (ii) Upon the payment to Landlord and Lender
of the Net Award of a Taking which falls within the provisions of this Paragraph
13(c), Landlord and Lender shall, to the extent received, make that portion of
the Net Award equal to the cost of Restoration (the "Restoration Award")
available to Tenant for Restoration, in accordance with the provisions of
Paragraph 15, and promptly after completion of the Restoration, the balance of
the Net Award shall be paid to Tenant and all Basic Rent, Additional Rent and
other sums payable hereunder shall continue unabated and unreduced.

                                    (iii) In the event of a Requisition of the
Leased Premises, Landlord shall apply the Net Award of such Requisition, to the
extent available, to the installments of Basic Rent, Additional Rent or other
sums payable by Tenant hereunder thereafter payable and Tenant shall pay any
balance remaining thereafter. Upon the expiration of the Term, any portion of
such Net Award which shall not have been previously credited to Tenant on
account of the Basic Rent and Additional Rent shall be retained by Landlord or
Landlord's successor in interest.

                            (d)     Except with respect to an award or payment
to which Tenant is entitled pursuant to the provisions of Paragraph 13(a), 13(b)
and 13(c), no agreement with any condemnor in settlement of or under threat
of any Condemnation shall be made by either Landlord or Tenant without the
written consent of the other, and of Lender, if the Leased Premises are then
subject to a Mortgage, which consent of Landlord and Tenant shall not be
unreasonably withheld or delayed.

14. Insurance.

                            (a) Tenant shall maintain at its sole cost and
expense the following insurance on the Leased Premises:

                                    (i) Insurance against loss or damage to the
Improvements and Equipment under a fire and broad form of all risk extended
coverage insurance policy (which shall include flood insurance if the Leased
Premises is located within a flood hazard area and which shall include
earthquake insurance if the Leased Premises is located in an area where
earthquake insurance is customarily maintained for similar commercial
properties). Such

                                       18


<PAGE>   22


insurance shall be in amounts sufficient to prevent Landlord or Tenant from
becoming a co-insurer under the applicable policies, and in any event in amounts
not less than the actual replacement cost of the Improvements and Equipment
(excluding footings and foundations and other parts of the Improvements which
are not insurable) as determined from time to time at Lender's request but not
more frequently than once in any 12-month period, by agreement of Landlord,
Lender and Tenant, or if not so agreed, at Tenant's expense, by the insurer or
insurers or by an appraiser approved by Landlord. Such insurance policies may
contain reasonable exclusions and deductible amounts.

                                    (ii) Contractual and comprehensive general
liability insurance against claims for bodily injury, death or property damage
occurring on, in or about the Leased Premises, which insurance shall be written
on a so-called "Occurrence Basis," and shall provide minimum protection with a
combined single limit in an amount not less than the greater of (x) Five Million
Dollars ($5,000,000) (or in such increased limits from time to time to reflect
declines in the purchasing power of the dollar as Landlord may reasonably
request) or (y) the aggregate amount of such insurance carried by Tenant, for
bodily injury, death and property damage in any one occurrence.

                                    (iii) Worker's compensation insurance
covering all persons employed by Tenant on the Leased Premises in connection
with any work done on or about any of the Leased Premises for which claims for
death or bodily injury could be asserted against Landlord, Tenant or the Leased
Premises.

                                    (iv) During periods of war or national
emergency, war risk insurance in an amount not less than the actual replacement
cost of the Improvements and Equipment (excluding footings and foundations and
other parts of the Improvements which are not insurable), when and to the extent
obtainable from the United States Government or an agency thereof at reasonable
cost.

                                    (v) Insurance against loss or damage from
explosion of any steam or pressure boilers or similar apparatus located in or
about the Improvements in an amount not less than the actual replacement cost of
the Improvements and Equipment (excluding footings and foundations and other
parts of the Improvements which are not insurable).

                                    (vi) Such additional and/or other insurance
with respect to the Improvements located on the Leased Premises and in such
amounts as at the time is customarily carried by prudent owners or tenants with
respect to improvements similar in character, location and use and occupancy to
the Improvements located on the Leased Premises.

                            (b)     During such time as (i) no Event of Default
is outstanding hereunder, (ii) the tangible net worth of Tenant (or of the
guarantor of Tenant's obligations under this Lease) shall be not less than One
Hundred Million Dollars ($100,000,000.00) as determined in accordance with
generally accepted accounting principles consistently applied, and (iii) Tenant


                                       19


<PAGE>   23


(or the guarantor of Tenant's obligations under this Lease) has a Standard &
Poors rating of BBB or better, Tenant may self-insure all or any portion of the
coverage referred to in Paragraph 14 (a) (i), (ii), (iii), (v) and (vi),
provided that the self insurance program of this section (b) does not violate
any Legal Requirements of any state which regulates a Lender domiciled in said
state.

                            (c) Except as otherwise provided in Paragraph 14(b),
the insurance required by Paragraph 14(a) shall be written by companies having a
claims paying ability rating by Standard & Poors of not less than A or an A.M.
Best Company rating of not less than A+, and all such companies shall be
authorized to do an insurance business in the State, or otherwise agreed to by
Landlord and Lender. Sums due from Tenant in lieu of insurance proceeds because
of such self-insurance programs shall be treated as insurance proceeds for all
purposes under this Lease. The insurance policies (i) shall be in amounts
sufficient at all times to satisfy any coinsurance requirements thereof, and
(ii) shall (except for the worker's compensation insurance referred to in
Paragraph 14 (a) (iii) hereof) name Landlord, Tenant and any Lender as
additional insured parties, as their respective interests may appear. If said
insurance or any part thereof shall expire, be withdrawn, become void by breach
of any condition thereof by Tenant or become void or unsafe by reason of the
failure or impairment of the capital of any insurer, Tenant shall immediately
obtain new or additional insurance reasonably satisfactory to Landlord and
Lender.

                            (d) Each insurance policy referred to in clauses
(i), (iv), (v) (and (vi) if requested by Lender) of Paragraph 14(a), shall
contain standard non-contributory mortgagee clauses in favor of any Lender which
holds a Mortgage on the Leased Premises. Each policy shall provide that it may
not be canceled except after 30 days prior notice to Landlord and any Lender.
Each policy shall also provide that any losses 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, or (ii) the occupation or use of any of the Leased
Premises for purposes more hazardous than permitted by the provisions of such
policy.

                            (e) Tenant shall pay as they become due all premiums
for the insurance required by this Paragraph 14, shall renew or replace each
policy, and shall deliver to Landlord and Lender a certificate or other evidence
(reasonably satisfactory to Lender and Landlord) of the existing policy and such
renewal or replacement policy at least thirty days prior to the Policy
Expiration Date (as hereinafter defined) of each policy. Each such policy shall
provide that it shall not expire until the Landlord and Lender shall receive a
notice from the insurer to the effect that a policy will expire on a date (the
"Policy Expiration Date") which shall be thirty (30) days following the date of
the receipt by Landlord and Lender of such notice. In the event of Tenant's
failure to comply with any of the foregoing requirements of this Paragraph 14
within five (5) business days of the giving of written notice by Landlord to
Tenant, Landlord shall be entitled to procure such insurance. Any sums expended
by Landlord in procuring such insurance shall be Additional Rent and shall be
repaid by Tenant, together with interest thereon at the Default Rate, from the
time of payment by Landlord until fully paid by Tenant immediately upon written
demand therefor by Landlord.

                                       20


<PAGE>   24




                            (f) Anything in this Paragraph 14 to the contrary
notwithstanding, any insurance which Tenant is required to obtain pursuant to
Paragraph 14(a) may be carried under a "blanket" policy or policies covering
other properties or liabilities of Tenant, provided that such "blanket" policy
or policies otherwise comply with the provisions of this Paragraph 14. In the
event any such insurance is carried under a blanket policy, Tenant shall deliver
to Landlord and Lender evidence of the issuance and effectiveness of the policy,
the amount and character of the coverage with respect to the Leased Premises and
the presence in the policy of provisions of the character required in the above
sections of this Paragraph 14.

                            (g) In the event of any casualty loss exceeding
$500,000, Tenant shall give Landlord immediate notice thereof. Tenant shall
adjust, collect and compromise any and all claims, with the consent of Lender
and Landlord, not to be unreasonably withheld or delayed, and Landlord and
Lender shall have the right to join with Tenant therein. If the estimated cost
of Restoration or repair shall be Five Hundred Thousand Dollars ($500,000.00) or
less, all proceeds of any insurance required under clauses (i), (iv), (v) (and
(vi) if requested by Lender) of Paragraph 14(a) shall be payable to Tenant,
provided that Tenant (or the guarantor of the Tenant's obligations under this
Lease) at such time shall have a tangible net worth of not less than One Hundred
Million Dollars ($100,000,000.00) as determined in accordance with generally
accepted accounting principles, consistently applied, and in all other events to
a Trustee which shall be a federally insured bank or other financial
institution, selected by Landlord and Tenant and reasonably satisfactory to
Lender (the "Trustee"). If the Leased Premises shall be covered by a Mortgage,
Lender, if it so desires, shall be the Trustee. Each insurer is hereby
authorized and directed to make payment under said policies directly to such
Trustee instead of to Landlord and Tenant jointly; and Tenant and Landlord each
hereby appoints such Trustee as its attorney-in-fact to endorse any draft
therefor for the purposes set forth in this Lease after approval by Tenant of
such Trustee, if Trustee is other than Lender. In the event of any casualty
(whether or not insured against) resulting in damage to the Leased Premises or
any part thereof, the Term shall nevertheless continue and there shall be no
abatement or reduction of Basic Rent, Additional Rent or any other sums payable
by Tenant hereunder. The Net Proceeds of such insurance payment shall be
retained by the Trustee and, promptly after such casualty, Tenant, as required
in Paragraphs 11(a) and 12, shall commence and diligently continue to perform
the Restoration to the Leased Premises. Upon payment to the Trustee of such Net
Proceeds, the Trustee shall, to the extent available, make the Net Proceeds
available to Tenant for Restoration, in accordance with the provisions of
Paragraph 15. Tenant shall, whether or not the Net Proceeds are sufficient for
the purpose, promptly repair or replace the Improvements and Equipment in
accordance with the provisions of Paragraph 11(a) and the Net Proceeds of such
loss shall thereupon be payable to Tenant, subject to the provisions of
Paragraph 15 hereof. In the event that any damage or destruction shall occur at
such time as Tenant shall not have maintained third-party insurance in
accordance with Paragraph 14(a)(i),(iv),(v) or (vi), Tenant shall pay to the
Trustee the amount of the proceeds that would have been payable had such
insurance program been in effect (the "Tenant Insurance Payment").

15.               Restoration. Net Proceeds, Restoration Award and Tenant
Insurance Payment (the aggregate of which being herein defined as the
"Restoration Fund") shall be disbursed by the Trustee in accordance with the
following conditions:

                            (a) If the cost of Restoration will exceed
$1,000,000, prior to commencement of the Restoration the architects, general
contractor(s), and plans and specifications for the Restoration shall be
approved by Landlord, which approval shall not be unreasonably withheld or
delayed; and which approval shall be granted to the extent that the plans and
specifications depict a Restoration which is substantially similar to the
Improvements and Equipment which existed prior to the occurrence of the Casualty
or Taking, whichever is applicable.

                            (b) At the time of any disbursement, no Event of
Default shall exist and no mechanics' or materialmen's liens shall have been
filed and remain undischarged or unbonded.

                            (c) Disbursements shall be made from time to time in
an amount not exceeding the hard and soft cost of the work and costs incurred
since the last disbursement upon receipt of (1) satisfactory evidence, including
architects' certificates of the stage of completion, of the estimated cost of
completion and of performance of the work to date in a good and workmanlike
manner in accordance with the contracts, plans and specifications, (2) partial
releases of liens, and (3) other reasonable evidence of cost and payment so that
Landlord can verify that the amounts disbursed from time to time are represented
by work that is completed in place or delivered to the site and free and clear
of mechanics' lien claims.

                            (d) Each request for disbursement shall be
accompanied by a certificate of Tenant describing the work, materials or other
costs or expenses, for which payment is requested, stating the cost incurred in
connection therewith and stating that Tenant has not previously received payment
for such work or expense and the certificate to be delivered by Tenant upon
completion of the work shall, in addition, state that the work has been
substantially completed and complies with the applicable requirements of this
Lease.

                            (e) The Trustee may retain ten percent (10%) of the
Restoration Fund until the Restoration is at least fifty percent (50%) complete,
and thereafter five percent (5%) until the Restoration is substantially
complete.

                            (f) The Restoration Fund shall be kept in a separate
interest-bearing federally insured account by the Trustee or by Lender.

                            (g) At all times the undisbursed balance of the
Restoration Fund held by Trustee plus any funds contributed thereto by Tenant,
at its option, shall be not less than the cost of completing the Restoration,
free and clear of all liens.

                                       22


<PAGE>   26


                            (h) In addition, prior to commencement of
Restoration and at any time during Restoration, if the estimated cost of
Restoration, as reasonably determined by Landlord, exceeds the amount of the Net
Proceeds, the Restoration Award and Tenant Insurance Payment available for such
Restoration, the amount of such excess shall be paid by Tenant to the Trustee to
be added to the Restoration Fund or Tenant shall fund at its own expense the
costs of such Restoration until the remaining Restoration Fund is sufficient for
the completion of the Restoration. Any sum in the Restoration Fund which remains
in the Restoration Fund upon the completion of Restoration shall be paid 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
Proceeds or the Restoration Award shall be deemed to have been disbursed for
Restoration prior to any amount added by Tenant.

16.      Subordination to Financing.


                            (a)     (i) Subject to the provisions of Paragraph
16 (a)(ii), Tenant agrees that this Lease shall at all times be subject and
subordinate to the lien of any Mortgage, and Tenant agrees, upon demand, without
cost, to execute instruments as may be required to further effectuate or confirm
such subordination.

                                    (ii) Except as expressly provided in this
Lease by reason of the occurrence of an Event of Default, Tenant's tenancy and
Tenant's rights under this Lease shall not be disturbed, terminated or otherwise
adversely affected, nor shall this Lease be affected, by any default under any
Mortgage, and in the event of a foreclosure or other enforcement of any
Mortgage, or sale in lieu thereof, the purchaser at such foreclosure sale shall
be bound to Tenant for the Term of this Lease, the rights of Tenant under this
Lease shall expressly survive, and this Lease shall in all respects continue in
full force and effect so long as no Event of Default has occurred and is
continuing. Tenant shall not be named as a party defendant in any such
foreclosure suit, except as may be required by Law. Any Mortgage to which this
Lease is now or hereafter subordinate shall provide, in effect, that during the
time this Lease is in force insurance proceeds and Restoration Award shall be
permitted to be used for Restoration in accordance with the provisions of this
Lease. Notwithstanding an Event of Default, but provided no event of default has
occurred under the Qualified Sublease, the provisions of this Paragraph 16 (a)
shall continue to apply for the benefit of any Qualified Subtenant referred to
in Paragraph 17 herein.

                            (b) Notwithstanding the provisions of Paragraph
16(a), the holder of any Mortgage to which this Lease is subject and subordinate
shall have the right, at its sole option, at any time, to subordinate and
subject the Mortgage, in whole or in part, to this Lease by recording a
unilateral declaration to such effect, provided that such holder shall have
agreed that during the time this Lease is in force insurance proceeds and
Restoration Award shall be permitted to be used for restoration in accordance
with the provisions of this Lease.

                            (c) At any time prior to the expiration of the Term,
Tenant agrees, at the election and upon demand of any owner of the Leased
Premises, or of a Lender who has

                                       23


<PAGE>   27

granted non-disturbance to Tenant pursuant to Paragraph 16(a) above, to attorn,
from time to time, to any such owner or Lender, upon the terms and conditions of
this Lease, for the remainder of the Term. The provisions of this Paragraph
16(c) shall inure to the benefit of any such owner or Lender, shall apply
notwithstanding that, as a matter of law, this Lease may terminate upon the
foreclosure of the Mortgage, shall be self-operative upon any such demand, and
no further instrument shall be required to give effect to said provisions.

                  (d) Each of Tenant, any owner and Lender, however, upon demand
of the other, hereby agrees to execute, from time to time, instruments in
confirmation of the foregoing provisions of Paragraphs 16(a) and 16(c),
reasonably satisfactory to the requesting party acknowledging such
subordination, non-disturbance and attornment as are provided in such
subsections and setting forth the terms and conditions of its tenancy.

                  (e) Each of Tenant, Landlord and Lender agrees that, if
requested by any of the others, each shall, without charge, enter into a
Subordination, Non-Disturbance and Attornment Agreement reasonably requested by
Lender, provided such agreement contains provisions relating to non-disturbance
in accordance with the provisions of subparagraph (a) and Tenant hereby agrees
for the benefit of Lender that Tenant will not, (i) without in each case the
prior written consent of Lender, which shall not be unreasonably withheld,
conditioned or delayed, amend or modify the Lease (provided, however, Lender, in
Lender's sole discretion may withhold or condition its consent to any amendment
or modification which would or could (A) alter in any way the amount or time for
payment of any Basic Rent, Additional Rent or other sum payable hereunder, (B)
alter in any way the absolute and unconditional nature of Tenant's obligations
hereunder or materially diminish any such obligations, (C) result in any
termination hereof prior to the end of the initial term, or (D) otherwise, in
Lender's reasonable judgment, affect the rights or obligations of Landlord or
Tenant hereunder), or enter into any agreement with Landlord so to do, (ii)
without the prior written consent of Lender which may be withheld in Lender's
sole discretion, cancel or surrender or seek to cancel or surrender the Term
hereof, or enter into any agreement with Landlord to do so (the parties agreeing
that the foregoing shall not be construed to affect the rights or obligations of
Tenant, Landlord or Lender with respect to any termination permitted under the
express terms hereof in connection with an offer to purchase the Leased Premises
following certain events of Condemnation as provided in Section 13 hereof), or
(iii) pay any installment of Basic Rent more than one (1) month in advance of
the due date thereof or otherwise than in the manner provided for in this Lease.

17.      Assignment, Subleasing.


                  (a) (i) Except as specifically provided in this Paragraph 17,
Tenant may not assign this Lease, voluntarily or involuntarily, whether by
operation of law or otherwise, or sublet any of the Leased Premises at any time
to any other Person without the prior written consent of Landlord, which
consent, in the event of an assignment, may be withheld by Landlord for any
reason or no reason, in Landlord's sole discretion, and any such purported
sublease or assignment shall be null and void.



                                       24


<PAGE>   28




                      (ii) Notwithstanding the provisions of subparagraph 17(a)
above, Tenant shall have the right, upon thirty (30) days prior written notice
to Landlord, with no consent of Landlord being required or necessary, to assign
this Lease or to sublet any portion of the Leased Premises (i) to any Person,
provided that, after giving effect to such assignment or sublease, Guarantor has
a consolidated net worth of not less than $80,000,000 and (ii) to any Person
that is, and for a period of at least thirty six (36) months from the effective
date of such assignment or sublease, as applicable, continues to be, a
wholly-owned subsidiary or Affiliate of Tenant.

                  (b) Each sublease of the Leased Premises or any part thereof
shall be subject and subordinate to the provisions of this Lease. No assignment
or sublease shall affect or reduce any of the obligations of Tenant hereunder,
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. Notwithstanding any assignment or subletting Tenant
shall continue to remain liable and responsible for the payment of the Basic
Rent and Additional Rent and the performance of all its other obligations under
this Lease. No assignment or sublease shall impose any obligations on Landlord
under this Lease except as otherwise provided in this Lease. Tenant agrees that
in the case of an assignment of the Lease, Tenant shall, within fifteen (15)
days after the execution and delivery of any such assignment, deliver to
Landlord (i) a duplicate original of such assignment in recordable form and (ii)
an agreement executed and acknowledged by the assignee in recordable form
wherein the assignee shall agree to assume and agree to observe and perform all
of the terms and provisions of this Lease on the part of the Tenant to be
observed and performed from and after the date of such assignment. In the case
of a sublease, Tenant shall, within fifteen (15) days after the execution and
delivery of such sublease, deliver to Landlord a duplicate original of such
sublease.

                  (c) Upon the occurrence of an Event of Default under this
Lease, Landlord shall have the right to collect and enjoy all rents and other
sums of money payable under any sublease of any of the Leased Premises, and
Tenant hereby irrevocably and unconditionally assigns such rents and money to
Landlord, which assignment may be exercised upon and after (but not before) the
occurrence of an Event of Default.

                  (d) (i) Landlord agrees for itself, its successors and
assigns, promptly upon Tenant's request, to enter into a nondisturbance and
attornment agreement with any Qualified Subtenant, as defined below, upon the
terms described below, pursuant to which Landlord shall agree, for so long as
such Qualified Subtenant is not in default under its Qualified Sublease, as
defined below, that the Qualified Sublease shall not be terminated as a result
of any termination of this Lease and such Qualified Subtenant's use and
occupancy of the Leased Premises shall not be disturbed by Landlord, and
pursuant to which such Qualified Subtenant shall agree to attorn to Landlord or
its successor as landlord under the Qualified Sublease upon any termination of
this Lease. Said agreement shall further provide that nothing therein contained
shall impose any obligation on the Landlord or the Lender to (A) return or apply
any security deposit under such Qualified Sublease, unless such security deposit
shall be transferred and turned over to the Landlord or Lender or their or
either of their successors, (B) expend any



                                       25



<PAGE>   29


sums to make any installations or alterations provided to be made by the
Landlord under said Qualified Sublease or reimburse the Tenant under said
Qualified Sublease for any installations or alterations made by it, (C) be
liable for any act or omission of Tenant as sublandlord (or any successor to
Tenant as sublandlord) or be subject to any offsets or defense which such
Qualified Subtenant might have against Tenant as sublandlord (or any successor
to Tenant as sublandlord), (D) be bound by any rent or additional rent which
such Qualified Subtenant might have paid for more than the current month to any
prior landlord, or (E) be bound by any amendment or modification of the
Qualified Sublease made without the prior written consent of Landlord, the terms
of which amendment or modification if included in the original sublease would
have prevented such sublease from meeting the criteria for a Qualified Sublease.

                      (ii) Any subtenant under a Qualified Sublease, as defined
below, is a "Qualified Subtenant." A "Qualified Sublease" shall be any sublease
of at least 100,000 square feet of the Leased Premises, pursuant to which the
subtenant thereunder had, at the time such sublease was entered into, a Standard
& Poor's investment grade rating of BBB-, or higher or a Moody's investment
grade rating of Baa3, or higher (or equivalent rating of any other nationally
recognized statistical rating organization) and was not on credit watch, such
sublease to be on the terms and conditions of this Lease (except the Basic Rent
per square foot or Additional Rent per square foot (or both) may be higher), and
for a term not to exceed the Term of this Lease.

                  (e) (i) Landlord agrees for itself, its successors and
assigns, promptly upon Tenant's request, to enter into an agreement with any
Qualified Assignee, as defined below, pursuant to which Landlord shall agree,
for so long as such Qualified Assignee is not in default of its obligations
under this Lease, that no defaults or Event of Default shall be deemed to have
occurred under this Lease by reason of the occurrence of one or more of the
events designated in Paragraphs 19(a)(iii), (iv), (v) or (vi) with respect to
any party who was a Tenant under this Lease prior to the date of the assignment
of this Lease to the Qualified Assignee.

                      (ii) A "Qualified Assignee" shall be any assignee of the
Tenant's rights, title and interest under this Lease which, at the time of the
assignment to it, had a Standard & Poor's investment grade rating of BBB-, or
higher, or a Moody's investment grade rating of Baa3, or higher, (or equivalent
rating of any other nationally recognized statistical rating organization) and
was not on credit watch.

                  (f) If Tenant sublets the Leased Premises in whole or in part,
Tenant shall, whether or not Landlord's consent thereto was required hereunder,
deliver to Landlord a true copy of the executed sublease no later than ten (10)
days of the date of execution and delivery thereof. If at any given time Tenant
shall sublet, pursuant to one or more subleases, in excess of 15% of the gross
leasable area of the Improvements (in the aggregate), then, with respect to such
subleases in excess of such 15% threshold only, Tenant shall receive as trust
funds and pay over to Landlord the excess of (x) a sum equal to (i) any rent or
other consideration paid to Tenant by any such subtenant in excess of the Basic
Rent plus any Additional Rent (payable pursuant to Article 32) for such space
then being paid by Tenant to Landlord pursuant to the provisions of


                                       26



<PAGE>   30


this Lease, plus (ii) any other amount received by Tenant from or in connection
with such subletting, including, in either case, but not limited to, sums paid
for the sale or rental of Tenant's fixtures, leasehold improvements, equipment,
furniture or other personal property, over (y) the actual reasonable
out-of-pocket costs of Tenant in making such sublease for (a) reasonable and
customary brokerage fees, (b) reasonable improvement and alteration costs to
prepare such portion of the Leased Premises for such subletting, provided that
such costs, and the improvement and alterations for such subtenant shall be
consistent with then current market terms for similar leases in similar quality
buildings located in the vicinity of the Leased Premises and (c) any actual
out-of-pocket costs paid by Tenant to Landlord, Lender or their respective
counsel under this Lease for any approval by Landlord or Lender of the proposed
sublease. All sums payable hereunder by Tenant shall be paid to Landlord as
Additional Rent immediately upon the receipt thereof by Tenant.

18. Permitted Contests.

                  (a) After prior written notice to Landlord, Tenant shall not
be required to (i) pay any Imposition, (ii) comply with any Legal Requirement,
(iii) discharge or remove any lien referred to in Paragraphs 9 or 12, or (iv)
take any action with respect to any violation referred to in Paragraph 11(b) so
long as Tenant shall contest, in good faith and at its expense, the existence,
the amount or the 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 (A) the collection
of, or other realization upon, the Imposition or lien so contested, (B) the
sale, forfeiture or loss of any of the Leased Premises, any Basic Rent or any
Additional Rent to satisfy the same or to pay any damages caused by the
violation of any such Legal Requirement or by any such violation, (C) any
interference with the use or occupancy of any of the Leased Premises, (D) any
interference with the payment of any Basic Rent or any Additional Rent, and (E)
the cancellation of any fire or other insurance policy.

                  (b) In no event shall Tenant pursue any contest with respect
to any Imposition, Legal Requirement, lien, or violation, referred to above in
such manner that exposes Landlord or Lender to (i) criminal liability, penalty
or sanction, (ii) any civil liability, penalty or sanction for which Tenant has
not made provisions reasonably acceptable to Landlord and Lender or (iii)
defeasance of its interest in the Leased Premises.

                  (c) Tenant agrees that each such contest shall be promptly and
diligently prosecuted to a final conclusion, except that Tenant shall have the
right to attempt to settle or compromise such contest through negotiations.
Tenant shall pay and save Lender and Landlord harmless against any and all
losses, judgments, decrees and costs (including all attorneys' fees and
expenses) 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, costs and expenses thereof or in connection therewith, and perform all
acts the performance of which shall be ordered or decreed as a result thereof.

19.  Conditional Limitations; Default Provisions.

                  (a) The occurrence of any one or more of the following events
(any such event being specified herein as a "failure" or "default") shall
constitute an Event of Default under this Lease: (i) a failure by Tenant to make
(regardless of the pendency of any bankruptcy, reorganization, receivership,
insolvency or other proceedings, in law, in equity or before any administrative
tribunal which had or might have the effect of preventing Tenant from complying
with the provisions of this Lease): (x) any payment of Basic Rent which
continues unremedied for a period of three (3) business days after written
notice ("Nonpayment Notice") thereof given to Tenant by Landlord or Lender or
Lender's designee, or (y) any payment of Additional Rent or other sum herein
required to be paid by Tenant which continues unremedied for a period of fifteen
(15) business days after a Nonpayment Notice is given to Tenant by Landlord or
Lender or Lender's designee; (ii) failure by Tenant to perform and observe, or a
violation or breach of, any other provision in this Lease and such default shall
continue for a period of sixty (60) business days after written notice thereof
is given by Landlord or Lender or Lender's designee to Tenant or if such default
is of such a nature that it cannot reasonably be cured within such period of
sixty (60) business days, such period shall be extended for such longer time as
is reasonably necessary provided that Tenant has commenced to cure such default
within said period of sixty (60) business days and is actively, diligently and
in good faith proceeding with continuity to remedy such default; (iii) Tenant or
any guarantor of Tenant's obligations hereunder shall (A) voluntarily be
adjudicated a bankrupt or insolvent, (B) or voluntarily consent to the
appointment of a receiver or trustee for itself or for any of the Leased
Premises, (C) voluntarily file a petition seeking relief under the bankruptcy or
other similar laws of the United States, any state or any jurisdiction, or (D)
voluntarily file a general assignment for the benefit of creditors; (iv) a court
shall enter an order, judgment or decree appointing, with the voluntary consent
of Tenant or any guarantor of Tenant's obligations hereunder, a receiver or
trustee for Tenant or any guarantor of Tenant's obligations hereunder or for the
Leased Premises or approving a petition filed against Tenant or any guarantor of
Tenant's obligations hereunder which seeks relief under the bankruptcy or other
similar laws of the United States or any State, and such order, judgment or
decree shall remain in force, undischarged or unstayed, 180 business days after
it is entered; (v) Tenant or any guarantor of Tenant's obligations hereunder
shall in any insolvency proceedings be liquidated or dissolved or shall
voluntarily commence proceedings towards its liquidation or dissolution; or (vi)
the estate or interest of Tenant in 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 180
business days after such levy or attachment.

                  (b) If any Event of Default shall have occurred, Landlord
shall have the right at its option, then or at any time thereafter while such
Event of Default is continuing, to do any one or more of the following without
demand upon or notice to Tenant:

                           (i) Landlord may give Tenant notice (following the
occurrence of an Event of Default) of Landlord's intention to terminate this
Lease on a date specified in such notice (which date shall be no sooner than
thirty (30) days after the date of the notice). Upon the

                                       28






<PAGE>   32



date therein specified, unless the Event of Default for which the termination is
effected has been cured by Tenant, the Term and the estate hereby granted and
all rights of Tenant hereunder shall expire and terminate as if such date were
the date herein above fixed for the expiration of the Term, but Tenant shall
remain liable for all its obligations hereunder through the date herein above
fixed for the expiration of the Term, including its liability for Basic Rent and
Additional Rent as hereinafter provided.

                           (ii) Landlord may, whether or not the Term of this
Lease shall have been terminated pursuant to clause (i) above give Tenant notice
(following the occurrence of an Event of Default) to surrender the Leased
Premises to Landlord on a date specified in such notice (which date shall be no
sooner than thirty (30) days after the date of the notice), at which time Tenant
shall surrender and deliver possession of the Leased Premises to Landlord unless
the Event of Default for which the termination is effected has been cured by
Tenant. Upon or at any time after taking possession of the Leased Premises,
Landlord may remove any persons or property therefrom. Landlord shall be under
no liability for or by reason of any such entry, repossession or removal. No
such entry or repossession shall be construed as an election by Landlord to
terminate this Lease unless Landlord gives a written notice of such intention to
Tenant pursuant to clause (i) above.

                           (iii) After repossession of any of the Leased
Premises pursuant to clause (ii) above, whether or not this Lease shall have
been terminated pursuant to clause (i) above, Landlord may relet the Leased
Premises or any part thereof to such tenant or tenants for such term or terms
(which may be greater or less than the period which would otherwise have
constituted the balance of the Term) for such rent, on such conditions (which
may include concessions or free rent) and for such uses as Landlord, in its
reasonable discretion, may determine; and Landlord shall collect and receive any
rents payable by reason of such reletting. The rents received on such reletting
shall be applied (A) first to the reasonable and actual expenses of such
reletting and collection, including without limitation necessary renovation and
alterations of the Leased Premises, reasonable and actual attorneys' fees and
any reasonable and actual real estate commissions paid, and (B) thereafter
toward payment of all sums due or to become due Landlord hereunder. If a
sufficient amount to pay such expenses and sums shall not be realized or
secured, then Tenant shall pay Landlord any such deficiency monthly, and
Landlord may bring an action therefor as such monthly deficiency shall arise.
Landlord shall not, in any event, be required to pay Tenant any sums received by
Landlord on a reletting of the Leased Premises in excess of the rent provided in
this Lease, but such excess shall reduce any accrued present or future
obligations of Tenant hereunder. Landlord's re-entry and reletting of the Leased
Premises without termination of this Lease shall not preclude Landlord from
subsequently terminating this Lease as set forth above. Landlord may make such
Alterations as Landlord in its reasonable discretion may deem advisable. Tenant
agrees to pay Landlord, as Additional Rent, immediately upon demand, all
reasonable expenses incurred by Landlord in obtaining possession, in performing
Alterations and in reletting any of the Leased Premises, including fees and
commissions of attorneys, architects, agents and brokers.

                           (iv) If Tenant shall fail to make payment of any
installment of Basic Rent or any Additional Rent on or before the date when each
such payment is due, Tenant shall


                                       29


<PAGE>   33


pay to Landlord, a sum equal to two (2%) percent per annum above the then
current Prime Rate, as hereinafter defined, of the amount unpaid (the "Default
Rate") computed from the date such payment of Basic Rent or Additional Rent was
due to and including the date of payment. The term "Prime Rate" shall mean the
prime rate of interest published in the Wall Street Journal or its successor,
from time to time.

                           (v) Landlord may exercise any other right or remedy
now or hereafter existing by law or in equity.

                  (c) In the event of any expiration or termination of this
Lease or repossession of any of the Leased Premises by reason of the occurrence
of an Event of Default, Tenant shall pay to Landlord Basic Rent, Additional Rent
and all other sums required to be paid by Tenant to and including the date of
such expiration, termination or repossession and, thereafter, Tenant shall,
until the end of what would have been the Term in the absence of such
expiration, termination or repossession, and whether or not any of the Leased
Premises shall have been relet, be liable to Landlord for and shall pay to
Landlord as liquidated and agreed current damages: (i) Basic Rent, Additional
Rent and all other sums which would be payable under this Lease by Tenant in the
absence of such expiration, termination or repossession, less (ii) the net
proceeds, if any, of any reletting pursuant to paragraph 19(b)(iii), after
deducting from such proceeds all of Landlord's reasonable expenses in connection
with such reletting (including all reasonable repossession costs, brokerage
commissions, legal expenses, attorneys' fees, employees' expenses, costs of
Alteration and expenses of preparation for reletting). Tenant hereby agrees to
be and remain liable for all sums aforesaid and Landlord may recover such
damages from Tenant and institute and maintain successive actions or legal
proceedings against Tenant for the recovery of such damages. Nothing herein
contained shall be deemed to require Landlord to wait to begin such action or
other legal proceedings until the date when the Term would have expired by
limitation had there been no such Event of Default.

                  (d) At any time after such expiration or sooner termination of
this Lease pursuant to Paragraph 19 or pursuant to Law or if Landlord shall have
reentered the Leased Premises, as the case may be, whether or not Landlord shall
have recovered any amounts under Paragraph 19(b)(iii) or 19(c), Landlord shall
be entitled to recover from Tenant and Tenant shall pay to Landlord, on demand,
as and for liquidated and agreed final damages for Tenant's default, the amount
by which the Basic Rent, and all Additional Rent reserved hereunder for the
unexpired portion of the Term demised herein as if the Lease had not expired or
been terminated exceeds the then fair and reasonable rental value of the Leased
Premises for the same period, discounted to present worth at the annual rate of
seven percent (7%), minus any such monthly deficiencies previously recovered
from Tenant under Paragraph 19(b)(iii) if applicable to such period.

                  (e) If any Law governing a proceeding in which such liquidated
final damages provided for in Paragraph 19(d) are to be proved shall validly
limit the amount thereof to an amount less than the amount above agreed upon,
Landlord shall be entitled to the maximum amount allowable under such Law.

20.    Additional Rights of Landlord and Tenant.


                  (a) No right or remedy conferred upon or reserved to Landlord
in this Lease is intended to be exclusive of any other right or remedy; and each
and every right and remedy shall be cumulative and in addition to any other
right or remedy contained in this Lease. No delay or failure by Landlord or
Tenant to enforce its rights under this Lease shall be construed as a waiver,
modification or relinquishment thereof. In addition to the other remedies
provided in this Lease, Landlord and Tenant shall be entitled, to the extent
permitted by applicable law, to injunctive relief in case of the violation or
attempted or threatened violation of any of the provisions of this Lease, or to
specific performance of any of the provisions of this Lease.

                  (b) Tenant hereby waives and surrenders for itself and all
those claiming under it, including creditors of all kinds, 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.

                  (c) Landlord hereby waives any right to distrain or levy upon
Trade Fixtures or any property of Tenant and any Landlord's lien or similar lien
upon Trade Fixtures and any other property of Tenant regardless of whether such
lien is created or otherwise. Landlord agrees at the request of Tenant, to
execute a waiver of any Landlord's or similar lien for the benefit of any
present or future holder of a security interest in or lessor of any of Trade
Fixtures or any other personal property of Tenant.

                  (d) Landlord acknowledges and agrees in the future to
acknowledge (in a written form reasonably satisfactory to Tenant) to such
persons and entities at such times and for such purposes as Tenant may
reasonably request that the Trade Fixtures are Tenant's property and not part of
the Improvements (regardless of whether or to what extent such Trade Fixtures
are affixed to the Improvements) or otherwise subject to the terms of this
Lease.

                  (e) Each of Tenant and Landlord (herein called "Paying Party")
agrees to pay to the other party (herein called "Demanding Party") any and all
reasonable costs and expenses incurred by the Demanding Party in connection with
any litigation or other action instituted by the Demanding Party to enforce the
obligations of the Paying Party under this Lease, to the extent that the
Demanding Party has prevailed in any such litigation or other action. Any amount
payable by Tenant to Landlord pursuant to this Paragraph 20(e) shall be due and
payable by Tenant to Landlord as Additional Rent. No sum payable by Landlord to
Tenant under this subparagraph will be payable or recoverable from any sums
pledged or assigned (or intended to have been pledged or assigned) by Landlord
to Lender, Tenant's right to recover such sums from Landlord being subordinate
to the rights of Lender, such sums only being recoverable after payment to
Lender in full of the Loan as constituted on the date hereof. As used in this
Paragraph, "costs and expenses" shall include, without

                                       31


<PAGE>   35





limitation, reasonable attorneys' fees at trial, on appeal and on any petition
for review, and in any proceeding in bankruptcy, in addition to all other sums
provided by Law.

21. 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 (collectively "Notice" or
"Notices") shall be in writing and shall be deemed to have been given for all
purposes (i) three (3) days after having been sent by United States mail, by
registered or certified mail, return receipt requested, postage prepaid,
addressed to the other party at its address as stated below, or (ii) one (1) day

to time, upon not less than twenty days' prior written request by the other,
execute, acknowledge and deliver to the other a statement in writing, certifying
(i) that this Lease is unmodified and in full effect (or, if there have been
modifications, that this Lease is in full effect as modified, setting forth such
modifications), (ii) the dates to which Basic Rent, payable hereunder has been
paid, (iii) that to the knowledge of the signer of such certificate no default
by either Landlord or Tenant exists hereunder or specifying each such default of
which the signer may have knowledge, (iv) the remaining Term hereof, (v) with
respect to a certificate signed on behalf of Tenant, that to the knowledge of
the signer of such certificate, there are no proceedings pending or threatened

It is intended that any such statements may be relied upon by Lender, the
recipient of such statements or their assignees or by any prospective purchaser,
assignee or subtenant of the Leased Premises.

23.  Surrender and Holding Over.

                  (a) Upon the expiration or earlier termination of this Lease,
Tenant shall peaceably leave and surrender the Leased Premises (except as to any
portion thereof with respect to which this Lease has previously terminated) to
Landlord. Tenant shall remove from the Leased Premises on or prior to such
expiration or earlier termination the Trade Fixtures and personal property which
is owned by Tenant or third parties other than Landlord, and Tenant at its
expense shall, on or prior to such expiration or earlier Termination, repair any
damage caused by such removal. Trade Fixtures and personal property not so
removed at the end of the Term or within thirty days after the earlier
termination of the Term for any reason whatsoever 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 borne by Tenant. Landlord shall not in any manner or to any extent be
obligated to reimburse Tenant for any property which becomes the property of
Landlord as a result of such expiration or earlier termination.





                                       33



<PAGE>   37
         (b) Any holding over by Tenant of the Leased Premises after the
expiration or earlier termination of the Term of this Lease or any extensions
thereof, with the consent of Landlord, shall operate and be construed as tenancy
from month to month only, at one hundred ten percent (110%) of the Basic Rent
reserved herein and upon the same terms and conditions as contained in this
Lease. Notwithstanding the foregoing, any holding over without Landlord's
consent shall entitle Landlord, in addition to collecting Basic Rent at a rate
of one hundred ten percent (110%) thereof, to exercise all rights and remedies
provided by law or in equity, including the remedies of Paragraph 19(b).

24. No Merger of Title. There shall be no merger of this Lease nor of the
leasehold estate created by this Lease with the fee estate in or ownership of
any of the Leased Premises by reason of the fact that the same person,
corporation, firm or other entity may acquire or hold or own, directly or
indirectly, (a) this Lease or the leasehold estate created by this Lease or any
interest in this Lease or in such leasehold estate and (b) the fee estate or
ownership of any of the Leased Premises or any interest in such fee estate or
ownership. No such merger shall occur unless and until all persons,
corporations, firms and other entities having any interest in (i) this Lease or
the leasehold estate created by this Lease and (ii) the fee estate in or
ownership of the Leased Premises or any part thereof sought to be merged shall
join in a written instrument effecting such merger and shall duly record the
same.

25. Definition of Landlord.

         (a) Anything contained herein to the contrary notwithstanding, any

local Laws, rules or regulations governing Hazardous Materials, Tenant shall
remove any hazardous substances (as defined in the Act) and Hazardous Materials
(as defined above) whether now or hereafter existing on the Leased Premises and
whether or not arising out of or in any manner connected with Tenant's occupancy
of the Leased Premises during the Term. In addition to, and without limiting
Paragraph 10 of this Lease Tenant shall and hereby does agree to defend,
indemnify and hold Lender and Landlord, their officers, directors, shareholders,
partners, beneficial owners, trustees, members, managers and employees, harmless
from and against any and all causes of actions, suits, demands or judgments of
any nature whatsoever, losses, damages, penalties, expenses, fees, claims, costs
(including response and remedial costs), and liabilities, including, but not
limited to, reasonable attorneys' fees and costs of litigation, arising out of
or in any manner connected with (i) the violation of any applicable federal,
state or local environmental Law with respect to the Leased Premises or Tenant's
or any other person's or entity's prior ownership of the Leased Premises; (ii)
the "release" or "threatened release" of or failure to remove, as required by

federal, state or local Laws, rules or regulations governing Hazardous
Materials.

27. Entry by Landlord. Landlord, Lender and their respective authorized
representatives shall have the right upon reasonable notice (which shall be not
less than two (2) business days except in the case of emergency) to enter the
Leased Premises at all reasonable business hours (and at all other times in the
event of an emergency): (a) for the purpose of inspecting the same or for the
purpose of doing any work under Paragraph 11(c), and may take all such action
thereon as may be necessary or appropriate for any such purpose (but nothing
contained in this Lease or otherwise shall create or imply any duty upon the
part of Landlord to make any such inspection or do any such work), (b) to
examine (and make copies of) the records and books of account and to discuss the
finances and business with the officers of Tenant, at such reasonable times as
may be requested by Landlord, and (c) for the purpose of showing the Leased
Premises to prospective purchasers and mortgagees and, at any time within six
(6) months prior to the expiration of the Term of this Lease for the purpose of
showing the same to prospective tenants. No such entry shall constitute an
eviction of Tenant but any such entry shall be done by Landlord in such
reasonable manner as to minimize any disruption of Tenant's business operation.

28. Statements.

         (a) Tenant shall keep adequate records and books of account with
respect to the finances and business of Tenant generally and with respect to the
Leased Premises, in accordance with generally accepted accounting principles
("GAAP") consistently applied. Upon the request of Lender or Landlord (either
telephonically or in writing), Tenant shall provide the requesting party with
copies of any information to which such party would be entitled in the course of
a personal visit.

         (b) If at any time neither Tenant nor Guarantor shall be a public
company subject to the reporting requirements of the Securities and Exchange Act
of 1934, or if financial statements meeting the criteria set forth below are not
readily available to Landlord through Edgar or an alternative on-line or
internet source, or by other means without any material cost to Landlord, then
(i) Tenant shall deliver or cause to be delivered to Landlord and to Lender (if
required under the terms of the Mortgage) within one hundred twenty (120) days
of the close of each fiscal year, annual audited financial statements of Tenant
and Guarantor prepared by a nationally recognized firm of independent certified
public accountants. Tenant shall also furnish to Landlord within forty-five (45)
days after the end of each of the three remaining quarters unaudited financial
statements and all other quarterly reports of Tenant and Guarantor, certified by
Tenant's or Guarantor's chief financial officer, as applicable, 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 shall be
prepared in accordance with GAAP consistently applied. All annual financial
statements shall be accompanied (i) by an opinion of said accountants stating
that (A) there are no qualifications as to the scope of the audit and (B) the
audit was performed in accordance with GAAP and (ii) 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 (C) 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


                                       36

<PAGE>   40


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 (D) 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.

29. No Usury. The intention of the parties being to conform strictly to the
applicable usury laws, whenever any provision herein provides for payment by
Tenant to Landlord of interest at a rate in excess of the legal rate permitted
to be charged, such rate herein provided to be paid shall be deemed reduced to
such legal rate.

30. Separability. Each and every covenant and agreement contained in this Lease
is, and shall be construed to be, a separate and independent covenant and
agreement, and the breach of any such covenant or agreement by Landlord shall
not discharge or relieve Tenant from its obligation to perform the same. If any
term or provision of this Lease or the application thereof to any provision of
this Lease or the application thereof to any person or circumstances shall to
any extent be invalid and unenforceable, the remainder of this Lease, or the
application of such term or provision to person or circumstances other than
those as to which it is invalid or unenforceable, shall not be affected thereby,
and each term and provision of this Lease shall be valid and shall be enforced
to the extent permitted by law.

31. Miscellaneous.

         (a) The paragraph headings in this Lease are used only for convenience
in finding the subject matters and are not part of this Lease or to be used in
determining the intent of the parties or otherwise interpreting this Lease.

         (b) As used in this Lease the singular shall include the plural as the

agreement, pledge, security interest, mortgage and/or deed of trust"; and (iv)

entity designated by Landlord. Any act which Tenant is required to perform under
this Lease shall be performed at Tenant's sole cost and expense.

         (d) 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.


                                       37

<PAGE>   41


         (e) The covenants of this Lease shall run with the Land and bind
Tenant, the successors and assigns of Tenant and all present and subsequent
encumbrancers and subtenants of any of the Leased Premises, and shall inure to
the benefit of and bind Landlord, its successors and assigns.

         (f) This Lease will be simultaneously executed in several counterparts,
each of which when so executed and delivered shall constitute an original, fully
enforceable counterpart for all purposes.

         (g) This Lease shall be governed by and construed according to the laws
of the State of Arizona.

         (h) Wherever the consent or approval of Landlord is required hereunder,
Landlord agrees that it will not unreasonably withhold or delay such consent or
approval.

32. Additional Rent. The term "Additional Rent" as used herein includes all
amounts, costs, expenses, liabilities and obligations (including but not limited
to Tenant's obligation to pay any Net Awards or Purchase Price hereunder) which
Tenant is required to pay pursuant to the terms of this Lease other than Basic
Rent

33. Right of First Offer.

         (a) If Landlord intends to offer the Leased Premises for sale to any
third party, Landlord shall first offer by written notice (the "Offer") to sell
the Leased Premises to Tenant for a specific purchase price (the "Purchase
Price") and, upon such terms and conditions as Landlord, in Landlord's sole
discretion, would otherwise intend to offer to sell the Leased Premises, prior
to Landlord's offering to sell the Leased Premises to any such third party
except that (i) the terms and conditions of any such sale to Tenant shall be (A)
consistent with the terms and provisions of this Paragraph 33 and (B) the sale
to Tenant shall be "as is", without representation or warranty by Landlord.
Landlord shall not be obligated to make the Offer (or, if Landlord has already
made the Offer, then, whether or not Tenant has accepted the Offer, Landlord
shall have the unilateral right, in Landlord's sole discretion, to revoke the
Offer) if an Event of Default exists under this Lease or the Guaranty on the
date on which Landlord shall give, or would otherwise be required to give,
Tenant the Offer.

         (b) Tenant shall have the right to accept the Offer only by giving
Landlord written notice of such acceptance (the "ROFO Notice") within thirty
(30) days after delivery by Landlord to Tenant of the Offer. Time shall be of
the essence with respect to said thirty (30) day period and delivery of the ROFO
Notice by Tenant. Upon Tenant's acceptance of the Offer, Tenant shall execute,
upon the request of Landlord, any documentation reasonably required by Landlord
to reflect Tenant's acceptance of the Offer. Notwithstanding anything to the
contrary contained in this Lease, subject only to the provisions of subparagraph
(d) below, upon the delivery of the ROFO Notice by Tenant, no event or
circumstances affecting the Leased Premises


                                       38

<PAGE>   42


including, but not limited to, a condemnation or casualty, shall give Tenant any
right or option of Tenant to cancel, surrender or otherwise terminate this
Lease, and any other right or option of Tenant under the Lease to acquire the
Leased Premises, shall automatically be deemed to have been waived by Tenant for
all purposes under this Lease.

         (c) If Tenant does not accept, or fails to accept, the Offer in
accordance with the provisions herein, Landlord shall be under no further
obligation with respect to such Offer pursuant to the terms contained herein,
and Tenant shall have forever waived and relinquished its right to such Offer,
and Landlord shall at any and all times thereafter be entitled to market the
Leased Premises to others upon such terms and conditions as Landlord in its sole
discretion may determine. Tenant shall, within five (5) days after Landlord's
request therefor, deliver an instrument in form reasonably satisfactory to
Landlord confirming the aforesaid waiver, but no such instrument shall be
necessary to make the provisions hereof effective. Notwithstanding anything to
the contrary contained in this subparagraph 33(c), in the event that Landlord
intends to offer the Leased Premises for sale to any third party for a purchase
price that is 7.5% or more below the Purchase Price offered to Tenant pursuant
to subparagraph 33(a) above, then Landlord shall again be required to offer the
Leased Premises for sale to Tenant in accordance with the provisions of
subparagraph 33(a) above; provided, however, Landlord shall not be obligated to
make such second Offer (or, if Landlord has already made the second Offer, then,
whether or not Tenant has accepted such second Offer, Landlord shall have the
unilateral right, in Landlord's sole discretion, to revoke the second Offer), if
(x) an Event of Default existed under this Lease or the Guaranty on the date on
which Landlord gave Tenant the initial Offer, or would otherwise have been
required to give Tenant the initial Offer, or (y) if an Event of Default exists
under this Lease or the Guaranty on the date on which Landlord shall give, or
would otherwise be required to give, Tenant the second Offer.

         (d) The rights of Tenant set forth herein are available only to the
Tenant first named in the heading of this Lease, and reference herein to
"Tenant" shall mean, and the rights accorded herein shall be available only to
Tenant and any assignee of this Lease that is an Affiliate of Tenant, and to no
other person, party or entity whatsoever, including, without limitation, any
subtenant of Tenant or any assignee of Tenant that is not an Affiliate at the
time in question, unless such rights are expressly granted by Landlord to such
party in a writing to such effect.

         (e) If Tenant does not timely deliver the ROFO Notice and the Leased
Premises are transferred to a third party, Tenant will attorn to such third
party as Landlord so long as such third party 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.

         (f) Notwithstanding anything to the contrary contained herein, the
provisions of this Paragraph 33 shall not apply to or prohibit (i) any
mortgaging, subjection to deed of trust


                                       39

<PAGE>   43


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
or their designees 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 or to any entity for whom W. P. Carey & Co. LLC or any of its
Affiliates provides management services or investment advice, (vi) any person or
entity to whom Landlord and its parent company sells all or substantially all of
its assets, or (vii) any transfer of the Leased Premises to any of the
successors or assigns of any of the persons or entities referred to in the
foregoing clauses (i) through (iv).

         (g) If the Leased Premises is purchased by Tenant pursuant to this
Paragraph 33, 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 of leases and rents 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.

         (h) Upon the date fixed for a purchase of the Leased Premises pursuant
to this Paragraph 33 (the "Purchase Date"), Tenant shall pay to Landlord, or to
any person or entity to whom Landlord directs payment, the Purchase Price and
all other sums payable by Tenant under the Offer, in federal funds, and Landlord
shall deliver to Tenant (i) a special warranty deed which describes the Leased
Premises being conveyed and conveys the title thereto as provided in Paragraph
33(g) above and (ii) such other instruments as shall be necessary to transfer
the Leased Premises to Tenant or its designee; provided, that if any payment of
Basic Rent, Additional Rent or any other sums payable by Tenant under this Lease
(the "Monetary Obligations") remain outstanding on the Purchase Date, then
Landlord may add to the Purchase Price 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 this Lease, then an amount
shall be added to the Purchase Price 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 pending resolution of such matter. If on the Purchase Date any
Monetary Obligations remain outstanding 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 obligations of Tenant under this Lease,
actual or contingent, which arise on or prior to the expiration or


                                       40

<PAGE>   44


termination of this Lease or which survive such expiration or termination by
their own terms. 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 Purchase Price due to Landlord; provided, that no
apportionment of any Impositions shall be made upon any such purchase.

                  (i) If the completion of the purchase by Tenant pursuant to
this Paragraph 33 shall be delayed after the date scheduled for such purchase,
Basic Rent and Additional Rent shall continue to be due and payable until
completion of such purchase.

                  IN WITNESS WHEREOF, Landlord and Tenant have caused this
instrument to be executed under seal as of the day and year first above written.

                                   EXHIBIT B

                   DETERMINATION OF FAIR MARKET RENTAL VALUE

     Fair Market Rental Value shall be determined in accordance with the
following procedure:

          (i)   "Landlord and Tenant shall endeavor to agree on Fair Market
Rental Value on the date (the "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 Rental Value.

          (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 following Landlord's receipt of Tenant's notice of the
appraiser selected by Tenant, 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 Rental Value, based on a
written appraisal made by each of them and given to both Landlord and Tenant),
as of the first day of the next occurring Renewal Term. If such two appraisers
shall agree upon a Fair Market Rental Value, the amount of such Fair Market
Rental Value as so agreed shall be binding and conclusive upon Landlord and
Tenant.

          (iii) If such two appraisers shall be unable to agree upon a Fair
Market Rental Value 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 Rental Value and shall select a third
appraiser to make the determination of Fair Market Rental Value. 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 Rental Value 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, be
appointed by the President or Chairman of the American Arbitration Association
in New York, New York. The determination of Fair Market Rental Value made by the
third appraiser appointed pursuant hereto shall be made within twenty (20) days
after such appointment.

          (v) If a third appraiser is selected, Fair Market Rental
