<PAGE>

     to the Closing. Seller and Purchaser hereby agree to prorate and pay their

          -------------------
terms of this Agreement, Seller's sole and exclusive remedy shall be to receive
the Earnest Money as liquidated damages and thereafter the parties hereto shall
have no further rights or obligations hereunder whatsoever. It is hereby agreed
that Seller's damages will be difficult to ascertain and that the Earnest Money
constitutes a reasonable liquidation thereof and is intended not as a penalty,
but as fully liquidated damages. Seller agrees that in the event of default by
Purchaser, it shall not initiate any proceeding to recover damages from
Purchaser, but shall limit its recovery to the retention of the Earnest Money.

                      -----------------                       -----------------

     16.  Seller's Default.  In the event of default by Seller under the terms
          ----------------
of this Agreement, including, without limitation, the failure of Seller to cure
any title defects or objections, except as otherwise specifically set forth
herein, at Purchaser's option: (i) if any such defects or objections arose by,
through, or under Seller or if any such defects or objections consist of taxes,
mortgages, deeds of trust, deeds to secure debt, mechanic's or materialman's
liens, or other such monetary encumbrances, Purchaser shall have the right to
cure such defects or objections, in which event the Purchase Price shall be
reduced by an amount equal to the costs and expenses incurred by Purchaser in
connection with the curing of such defects or objections, and upon such curing,
the Closing hereof shall proceed in accordance with the terms of this Agreement;
or (ii) Purchaser shall have the right to terminate this Agreement by giving
written notice of such termination to Seller, whereupon Escrow Agent shall
promptly refund all Earnest Money to Purchaser, and Purchaser and Seller shall
have no further rights, obligations, or liabilities hereunder, except as may be
expressly provided to the contrary herein; or (iii) Purchaser shall have the
right to accept title to the Property subject to such defects and objections
with no reduction in the Purchase Price, in which event such defects and
objections shall be deemed "Permitted Exceptions"; or (iv) Purchaser may elect
to seek specific performance of this Agreement.

     17.  Condemnation.  If, prior to the Closing, all or any part of the
          ------------
Property is subjected to a bona fide threat of condemnation by a body having the
power of eminent domain or is taken by eminent domain or condemnation (or sale
in lieu thereof), or if Seller has received notice that any condemnation action
or proceeding with respect to the Property is contemplated by a body having the
power of eminent domain, Seller shall give Purchaser immediate written notice of
such threatened or contemplated condemnation or of such taking or sale, and
Purchaser may by written notice to Seller given within thirty (30) days of the
receipt of such notice from Seller, elect to cancel this Agreement. If Purchaser
chooses to cancel this Agreement in accordance with this Paragraph 17, then the
Earnest Money shall be returned immediately to Purchaser by Escrow Agent and the
rights, duties, obligations, and liabilities of the parties hereunder shall
immediately terminate and be of no further force and effect. If Purchaser does
not elect to cancel this Agreement

                                       12
<PAGE>

in accordance herewith, this Agreement shall remain in full force and effect and
the sale of the Property contemplated by this Agreement, less any interest taken
by eminent domain or condemnation, or sale in lieu thereof, shall be effected
with no further adjustment and without reduction of the Purchase Price, and at
the Closing, Seller shall assign, transfer, and set over to Purchaser all of the
right, title, and interest of Seller in and to any awards that have been or that
may thereafter be made for such taking.

     18.  Damage or Destruction.  If any of the Improvements shall be destroyed
          ---------------------
or damaged prior to the Closing, and the estimated cost of repair or replacement
exceeds $100,000.00 or if the Lease shall terminate as a result of such damage,
Purchaser may, by written notice given to Seller within twenty (20) days after
receipt of written notice from Seller of such damage or destruction, elect to
terminate this Agreement, in which event the Earnest Money shall immediately be
returned by Escrow Agent to Purchaser and except as expressly provided herein to
the contrary, the rights, duties, obligations, and liabilities of all parties
hereunder shall immediately terminate and be of no further force or effect. If
Purchaser does not elect to terminate this Agreement pursuant to this Paragraph
18, or has no right to terminate this Agreement (because the damage or
destruction does not exceed $100,000.00 and the Lease remains in full force and
effect), and the sale of the Property is consummated, Purchaser shall be
entitled to receive all insurance proceeds paid or payable to Seller by reason
of such destruction or damage under the insurance required to be maintained by
Seller pursuant to Paragraph 9(d) hereof (less amounts of insurance theretofore
received and applied by Seller to restoration). If the amount of said casualty
or rent loss insurance proceeds is not settled by the date of Closing, Seller
shall execute at Closing all proofs of loss, assignments of claim, and other
similar instruments to ensure that Purchaser shall receive all of Seller's
right, title, and interest in and under said insurance proceeds.

     19.  Assignment.  Purchaser's rights and duties under this Agreement shall
          ----------
not be assignable except to an affiliate of Purchaser without the consent of
Seller which consent shall not be unreasonably withheld.

     20.  Broker's Commission.  Seller has by separate agreement agreed to pay a
          -------------------
brokerage commission to CB Commercial Real Estate Group (the "Broker").
Purchaser and Seller hereby represent each to the other that they have not
discussed this Agreement or the subject matter hereof with any real estate
broker or agent other than Broker so as to create any legal right in any such
broker or agent to claim a real estate commission with respect to the conveyance
of the Property contemplated by this Agreement. Seller shall and does hereby
indemnify and hold harmless Purchaser from and against any claim, whether or not
meritorious, for any real estate sales commission, finder's fees, or like
compensation in connection with the sale contemplated hereby and arising out of
any act or agreement of Seller, including any claim asserted by Brokers and any
broker or agent claiming under Broker.  Likewise, Purchaser shall and does
hereby indemnify and hold harmless Seller from and against any claim, whether or
not meritorious, for any real estate sales commission, finder's fees, or like
compensation in connection with the sale contemplated hereby and arising out of
any act or agreement of Purchaser, except any such claim asserted by Broker and
any broker or agent claiming under Broker. This Paragraph 21 shall survive the
Closing or any termination of this Agreement.

                                LEASE AGREEMENT
                                ---------------

          THIS LEASE AGREEMENT (the "Lease"), dated for reference purposes only
as of March 21, 1997, between Ryan Companies US, Inc., a Minnesota corporation,
formerly known as Ryan Construction Companies of Minnesota, Inc., a Minnesota
corporation (hereinafter referred to as "Landlord"), and The Dial Corporation, a
Delaware corporation (hereinafter referred to as "Tenant").  Each defined term
used hereinbelow shall have the meaning ascribed to such term in Section 47
below.

          In consideration of the mutual agreements contained in this Lease,
Landlord and Tenant agree with each other as follows:

          1.  Leased Property.  Upon and subject to the conditions and
              ---------------
limitations set forth below, Landlord hereby leases to Tenant, and Tenant hereby
leases and rents from Landlord, the following real property ("Property")
situated in the City of Scottsdale, County of Maricopa, State of Arizona,
described as follows:

              (a) Those certain parcels of real property consisting of
approximately 8.8375 acres, more particularly described in Exhibit "A" attached
hereto, together with the exclusive use of all parking areas (except as
otherwise provided in Section 41 hereof), access and perimeter roads, driveways,
sidewalks, landscape areas, service areas, trash disposal facilities, and
similar areas now or hereafter located thereon, together with all rights and
easements appurtenant thereto now or hereafter existing (collectively, the
"Parcels");

              (b) That certain existing two story building (the "Building") with
mezzanine located on one of the Parcels at the general location shown on the
Site Plan attached hereto as Exhibit "B" containing approximately 129,689 square
feet of Gross Building Area, consisting of approximately 102,000 square feet of
Gross Building Area on the first floor and 27,689 square feet of Gross Building
Area on the second floor mezzanine (subject to remeasurement as provided herein)
and other improvements to the Building and on the Parcels be constructed by
Landlord ("Landlord Work", as defined in the Improvement Agreement) in
accordance with the provisions of the Improvement Agreement attached hereto as
Exhibit "C" (the "Improvement Agreement"), together with all other buildings,
improvements and structures now or hereafter located on the Property.

          The Building and the Landlord Work are collectively referred to in
this Lease as the "Improvements".  During the Lease Term, Tenant shall have
access to the Property and into the interior of the Improvements 24 hours per
day, 7 days per week.

          2.  Lease Term.
              ----------

              2.1  Lease Term.  The term of this Lease (the "Lease Term") shall
                   ----------
commence on the Commencement Date (as defined below) and shall expire at
midnight on the last calendar day of the one hundred twenty sixth (126th) month
following the calendar month
<PAGE>

in which the Rental Commencement Date (as defined below) occurs, unless this
Lease shall sooner terminate as provided herein or shall be extended, as
provided in Section 36 below. Within five (5) days after the Commencement Date
and the Rental Commencement Date become ascertainable, as provided in Sections
2.2 and 2.3 below, Landlord and Tenant shall execute a written amendment to this
Lease specifying the Commencement Date, the Rental Commencement Date and the
date on which the Lease Term shall end, subject to the provisions of Section 36
below, a copy of which is attached hereto as Exhibit "F".

              2.2  Commencement Date.  As used in this Lease, the term
                   -----------------
"Commencement Date" shall mean the date when Landlord delivers to Tenant the
Property with the Landlord Work being Substantially Completed (as defined in the
Improvement Agreement) in a clean and tidy state, with vacant possession.
Landlord shall give Tenant at least thirty (30) days prior written notice of the
date when the Commencement Date shall occur.

              2.3  Rental Commencement Date.  As used in this Lease, the term
                   ------------------------
"Rental Commencement Date" shall mean the date six (6) months following the
Commencement Date, unless the Rental Commencement Date is delayed pursuant to
Section 2.4 below, in which case it shall mean such delayed date.

              2.4  Failure to Deliver.  The target date for the Commencement
                   ------------------
Date (the "Target Commencement Date") is July 15, 1997. For each day beyond
August 14, 1997 up to, but not including, September 15, 1997, that Landlord is
unable to deliver possession of the Property to Tenant with the Landlord Work
being Substantially Completed for any reason other than Excused Delay (as
defined in the Improvement Agreement), the Rental Commencement Date shall be
delayed on (1) day. For each day from and beyond September 15, 1997 up to, but
not including, October 15, 1997, that Landlord is unable to deliver possession
of the Property to Tenant with the Landlord Work being Substantially Completed
for any reason other than Excused Delay, the Rental Commencement Date shall be
delayed one and one-half (1 1/2) days. For each day from and beyond October 15,
1997 up to, but not including, November 14, 1997 that Landlord is unable to
deliver possession of the Property to Tenant with the Landlord Work being
Substantially Completed for any reason other than Excused Delay, the Rental
Commencement Date shall be delayed two (2) days. Notwithstanding the occurrence
of any Excused Delay (as defined in the Improvement Agreement, but excepting
from that definition any delays resulting solely from change orders requested by
Tenant, delays in Tenant's delivery of any plans or specifications to Landlord
beyond the date therefor set forth in the Improvement Agreement and delays in
Tenant's review of any plans and specifications submitted to Tenant for review
beyond the period for such review set forth in the Improvement Agreement, each
category of which delays shall extend the date set forth immediately below in
this Section 2.4 on a day for day basis, but only following Landlord's written
notice to Tenant of such delay as provided in the definition of Excused Delay in
the Improvement Agreement), if Landlord is unable to deliver possession of the
Property with the Landlord Work Substantially Completed on or before November
14, 1997, then Tenant shall have the right to terminate this Lease by giving
written notice of termination to Landlord at any time after such date, but prior
to the time that Landlord had delivered possession of the Property with the
Landlord Work Substantially

                                       2
<PAGE>

Completed to Tenant. Any such termination shall be in addition to any other
rights or remedies that Tenant may have under this Lease, at law or in equity,
unless Landlord's failure to cause the Landlord Work to be Substantially
Completed on or before November 14, 1997 is due primarily (i.e., more than 50%
of such delay) to Excused Delay, in which event Landlord's total liability to
Tenant resulting from such termination and delay shall be limited to an amount
equal to all documented, out-of-pocket costs incurred by Tenant (including,
without limitation, fees and costs of design and construction professionals,
consultants and attorneys) in connection with the negotiation and drafting of
this Lease, the diligence review of the Property and the space planning and
design of any of the Improvements.

               2.5  Early Entry.  Tenant shall be permitted to occupy the
                    -----------
Property four (4) weeks prior to the anticipated Commencement Date for the
purpose of installing Tenant's Equipment (including, without limitation,
telephone room equipment, computer cabling and work station furniture systems),
provided such early entry shall be at Tenant's sole risk and subject to all the
terms and provisions hereof, except for the payment of Basic Rent or Additional
Rent which shall commence on the Rental Commencement Date. Notwithstanding the
foregoing, Landlord shall use commercially reasonable efforts to take all
necessary precautions to protect such equipment from damage or theft during the
construction process. Tenant agrees that such early access shall not materially
interfere with the Landlord Work and shall not result in any additional costs to
Landlord, and Landlord and Tenant shall instruct their construction
professionals to coordinate their activities to this end.

          3.  Basic Rent.
              ----------

              3.1  Basic Rent.  Basic rent ("Basic Rent") shall be payable
                   ----------
monthly during the Lease Term commencing on the Rental Commencement Date in an
amount equal to the product of Ten and 70/100 Dollars ($10.70) per square foot
multiplied by the number of square feet of Gross Building Area contained within
the Improvements.

              3.2  Manner of Payment.  The Basic Rent and all other sums payable
                   -----------------
to Landlord hereunder shall be payable in such currency of the United States of
America as at time of payment shall be legal tender for the payment of public
and private debts and shall be paid to Landlord at Landlord's address set forth
below or to such other person or address as Landlord from time to time may
designate.

          4.  Additional Rent.  Tenant will also pay, from time to time on or
              ---------------
after the Rental Commencement Date, as provided in this Lease or on demand of
Landlord, as additional rent (the "Additional Rent") (a) all other amounts,
liabilities and obligations that Tenant herein expressly assumes or agrees to
pay, (b) together with each installment of Basic Rent, the amount of any
transaction privilege tax that is assessed against or payable by Landlord solely
as a result of this Lease, and (c) if the amounts specified in clauses (i) or
(ii) below, as applicable, are not paid to Landlord within five (5) days
following the delivery of written notice from Landlord to Tenant that such
amounts were not received when due (provided that such written notice shall be a
condition precedent to imposing such interest only one time in any twelve (12)
calendar

                                       3
<PAGE>

month period), then interest at the Interest Rate on (i) such of the
foregoing amounts, liabilities and obligations as are payable by Tenant but are
not paid when due and that Landlord shall have paid on behalf of Tenant in
accordance with its rights under Section 23 of this Lease, from the date of
payment thereof by Landlord until paid by Tenant and (ii) all overdue
installments of Basic Rent.

          5.  Net Lease.  Except as otherwise expressly provided in this Lease
              ---------
including, without limitation, Section 40 hereof, this Lease is a net lease, and
the Basic Rent, Additional Rent and all other sums payable hereunder shall be
paid without setoff or deduction.  Except as otherwise expressly provided in
this Lease including, without limitation, Sections 6, 19, 20, 21 and 40 hereof,
Tenant shall at all times remain bound by this Lease and shall at all times
remain obligated to pay the stated rentals required by this Lease.  Except as
specifically set forth in this Lease to the contrary, including, without
limitation, Sections 2, 20, 21 and 39 hereof, Tenant shall in no event have any
right to terminate this Lease.

          6.  Condition and Use of Property.  Subject to the provisions of the
              -----------------------------
Improvement Agreement and except as expressly provided below, Tenant, upon
acceptance of possession of the Property, acknowledges that Tenant will be fully
familiar with the physical condition of the Property and has received the same
in good and clean order and condition, and that the Property complies in all
respects with all requirements of this Lease.  Notwithstanding the foregoing to
the contrary, Landlord makes the following representations and warranties to
Tenant as of the Commencement Date:

              (a) There are no material physical, mechanical or other defects in
the design, construction or operation of any portion of the Improvements
(including, without limitation, the Building Systems) and all of the
Improvements (including, without limitation, the Building Systems) are in good
operating condition and repair;

              (b) The Property is in full compliance with all applicable Legal
Requirements including, without limitation, the Americans With Disabilities Act
of 1990, building codes, zoning and land use laws and environmental laws;

              (c) There are no condemnation, environmental, zoning or other
land-use regulation proceedings, either instituted or, to Landlord's actual
knowledge without investigation, planned to be instituted against the Property;

              (d) All water, sewer, gas, electric, telephone, and drainage
facilities and all other utilities required by Legal Requirements or by the
normal use and operation of the Property, are all connected pursuant to valid
permits, and are and will be adequate to service the Property for general office
purposes and to permit full compliance with all Legal Requirements and normal
usage of the Property by Tenant;

              (e) Landlord has obtained all licenses, permits, easements and
rights of way, including proof of dedication, required from all governmental
authorities having

                                       4
<PAGE>

jurisdiction over the Property or from private parties for the normal use and
operation of the Property and to insure vehicular and pedestrian ingress to and
egress from the Property over adjacent public highways, streets and roads and to
provide parking as required in this Lease;

              (f) There is no litigation pending or threatened against the
Property (or against Landlord, if such litigation against Landlord would
materially and adversely affect the Property);

              (g) Landlord is a Minnesota corporation, duly organized and
validly existing and in good standing under the laws of the State of Minnesota
and is in good standing under the laws of the State of Arizona;

              (h) The terms of this Lease or the Improvement Agreement do not
and will not violate any provisions of any agreement or judicial order to which
Landlord is a party or to which Landlord or the Property is subject; and

              (i) There are no persons or entities in occupancy or with a
possessory right in or to all or any portion of the Property and, to Landlord's
actual knowledge without investigation, there are no unrecorded easements or
claims of encroachment or prescriptive easements affecting the Property.

          Notwithstanding the foregoing representations and warranties, Landlord
shall not be deemed to have breached any such representation or warranty solely
as a result of conditions of the Property resulting from Tenant's design of the
Tenant Improvements.  All of the foregoing representations and warranties shall
survive termination of this Lease for a period of three years.  During the Lease
Term Landlord shall be responsible promptly to remedy at its sole cost any
violations of any of the foregoing representations and warranties to the extent
that Tenant's use or occupancy of the property shall be impaired as determined
by Tenant in its sole good faith judgment.  In addition, Base Rent and
Additional Rent shall be abated during the period between the date of such
discovery and the date such violation is fully remedied in proportion to the
degree to which Tenant's occupancy or use of the Property is so impaired.
Tenant may use the Property for any legal purpose and will not do or permit any
act or thing that is contrary to any Legal Requirement or Insurance Requirement,
or that may impair the value or utility of the Property or any part thereof, or
that constitutes a public or private nuisance or waste of the Property or any
part thereof.  Notwithstanding the foregoing, if Tenant proposes to change the
use of the Property from general office purposes to any other use that would
materially increase the use of Hazardous Materials (as defined in Section 19.1
below) upon the Property, Tenant shall not permit such change of use to occur
without Landlord's prior written consent, which consent shall not be
unreasonably withheld or delayed.

          7.  Maintenance and Repairs.  Except as provided below, Tenant at its
              -----------------------
expense will keep the Property and the adjoining sidewalks, curbs, landscaping
and all means of access to the Property in good and clean order and condition
(including painting the exterior of the Building at least one time every four
years following the Rental Commencement Date), subject

                                       5
<PAGE>

to ordinary wear and tear, and will promptly, at its own expense, make all
necessary or appropriate repairs, replacements and renewals thereof, whether
interior or exterior, ordinary or extraordinary, foreseen or unforeseen. All
repairs, replacements and renewals shall be at least equal in quality, utility
and class to the original condition of the Property. Not less frequently than
annually, Tenant shall cause an inspection of the Building Systems to occur and
shall cause any customary annual maintenance to be performed to the Building
Systems. At Landlord's request, Tenant shall deliver to Landlord reasonable
evidence that any such inspection or maintenance has occurred for the most
recent annual period. Notwithstanding the foregoing, Landlord, at its expense,
shall:

              (a) keep and maintain the structural elements of the Building in
good order, condition and repair, except to the extent any maintenance or repair
thereof is required because of the negligence or willful misconduct of Tenant
(and Landlord does not receive insurance proceeds therefor). (As used herein,
the term "structural elements of the Building" shall include, without
limitation, foundations, footings, floor slabs, walls, structural or exterior
roof structure, roofing and roof membrane);

              (b) enforce roof guaranties to maintain in good order and repair,
including replacing, as necessary, the roofing and roof membrane for a period of
ten (10) years commencing on the Commencement Date;

              (c) repair any latent defects in the Improvements;

              (d) perform any repairs or replacements, as necessary, to remedy
any violation of any warranty provided in Section 6 hereof;

              (e) perform any capital repairs, capital replacements and capital
improvements (as defined by GAAP) required to maintain the Building Systems;

              (f) so long as Landlord is also the owner of any land over which
any easements appurtenant to the Property are located, maintain such easement
areas located on land owned by Landlord in good order, condition and repair; and

              (g) so long as Landlord is also the owner of any land adjacent to
the Property, maintain such adjacent land owned by Landlord in a safe and
presentable condition.

          In addition to all of the foregoing, if Tenant is otherwise obligated
under this Section 7 to bear the cost of any capital improvement item whose
useful life (as determined in accordance with GAAP) exceeds the remainder of the
Lease Term (excluding extensions thereof unless Tenant shall have previously
exercised its extension option pursuant to Section 36 hereof), then,
notwithstanding any other provision of this Lease to the contrary, the cost of
such improvement item shall be prorated over its reasonably estimated useful
life, and the portion that is attributable to the period of time after
expiration of the Lease Term (excluding extensions thereof unless Tenant shall
have previously exercised its extension option pursuant to Section

                                       6
<PAGE>

36 hereof) shall be borne by Landlord and paid to Tenant promptly following
Tenant's written demand therefor. Prior to incurring any such cost for any
capital item, Tenant shall deliver written notice to Landlord that Tenant is
considering incurring such capital cost, and Tenant shall consult with Landlord
before incurring such cost. The foregoing sentence is a requirement that Tenant
consult with Landlord only, and shall not be understood to provide Landlord with
any approval right over Tenant's incurring any such capital cost.

          Landlord shall assign to Tenant for the term of this Lease the benefit
of all assignable warranties available to Landlord which would reduce the cost
of performing the obligations of Tenant to make repairs under this Section 7.
Landlord shall cooperate with Tenant in the enforcement of such warranties.
Notwithstanding any provision hereinabove to the contrary, Tenant shall have the
right, with respect to any repair obligations imposed on Landlord, to perform
such repair in lieu of Landlord and to be reimbursed by Landlord, upon demand,
for the costs of such repair.

          8.  Alterations and Additions.  Tenant at its expense may make
              -------------------------
alterations of and additions to the Property or any part thereof; provided,
however, that any such alteration or addition (a) shall not materially and
adversely change the general character of the Improvements located on the
Property, or materially reduce the fair market value of any such Improvements
immediately before such alteration or addition (assuming the Property was then
being maintained in accordance with the terms of this Lease), (b) shall be
effected with due diligence, in a good and workmanlike manner and in compliance
with all Legal Requirements, Insurance Requirements and the provisions of
Section 15 hereof, and (c) (except as may be permitted pursuant to Section 17
hereof) shall be fully paid for by Tenant upon its construction or installation
on the Property.  All alterations of and additions to the Improvements, other
than alterations and additions which Tenant elects to remove at the end of the
Term in accordance with its rights below, shall become the property of Landlord
upon termination of this Lease and shall remain on and constitute a part of the
Property.  Notwithstanding any provision hereinabove to the contrary, Tenant may
elect to (but shall not be obligated to) remove any alteration, addition or
improvement, other than the Improvements or other improvements paid for by
Landlord, at the end of the Lease Term and repair any damage caused by such
removal.

          9.  Tenant's Equipment.  All Tenant's Equipment shall remain the
              -------------------
property of Tenant at all times during the Lease Term.  Tenant will immediately
repair at its expense all damage to the Property caused by any removal of any of
the same from the Property.

          10. Utility Services.  Tenant will pay or cause to be paid all
              ----------------
charges of any nature for utilities, communications and other similar services
used by Tenant at the Property.  Landlord shall cause all applicable utilities
to be separately metered to the Property.  All utilities (including, without
limitation, HVAC service) shall be available to Tenant 24 hours per day, 7 days
per week, provided that Tenant pays the applicable charges to the applicable
public utilities providing such services to maintain such services in place.

                                       7
<PAGE>

          11.  No Claims Against Landlord.  Nothing contained in this Lease
               --------------------------
shall constitute any consent or request by Landlord or any Mortgagee, express or
implied, for the performance of any labor or services or the furnishing of any
materials or other property in respect of the Property or any part thereof, nor
as giving Tenant any right, power or authority to contract for or permit the
performance of any labor or services or the furnishing of any materials or other
property in such fashion as would permit the making of any claim against
Landlord or any Mortgagee in respect thereof. The foregoing sentence shall not
be understood to refer to statutory, inchoate mechanics' liens, unless the same
shall ripen into actual claims of lien, in which event the provisions of Section
17 shall apply.

          12.  Indemnities.  Tenant will (to the full extent permitted by
               -----------
applicable Legal Requirements) protect, indemnify and save harmless Landlord,
any beneficiary of Landlord, any officer, director or shareholder of any of the
foregoing and Mortgagee of the Property (each an "Indemnified Landlord Party")
from and against all liabilities, obligations, claims, damages, penalties,
causes of action, costs and expenses (including, without limitation, reasonable
attorneys' fees and expenses) imposed upon or incurred by or asserted against
any Indemnified Landlord Party or against the Property or any interest of such
Indemnified Landlord Party therein by reason of the occurrence or existence of
any of the following, during the term of this Lease, except to the extent caused
by the willful misconduct or negligence of such Indemnified Landlord Party or
the failure of any of the same to perform or comply with any term of this Lease:
(a) any accident, injury to or death of any person or persons or loss of or
damage to property occurring on or about the Property or any part thereof, or
any adjoining sidewalks, curbs, streets or ways, (b) Tenant's use of the
Property or any part thereof, or of the adjoining sidewalks, curbs, streets or
ways, (c) any failure on the part of Tenant to perform or comply with any of the
terms of this Lease, (d) any negligent or tortuous act on the part of Tenant or
any of its agents, contractors, servants, employees, licensees or invitees, or
(e) any negligent or tortious act on the part of any assignee or sublessee of
Tenant, or of any agents, contractors, servants, employees, licensees or
invitees of any assignee or sublessee of Tenant. Landlord will (to the full
extent permitted by applicable Legal Requirements) protect, indemnify and save
harmless Tenant, any beneficiary of Tenant, and any of Tenant's Agents, invitees
or licensees ("Indemnified Tenant Party") from and against all liabilities,
obligations, claims, damages, penalties, causes of action, costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) imposed
upon or incurred by or asserted against such Indemnified Tenant Party to the
extent caused by the willful misconduct or negligence of Landlord or any
Indemnified Landlord Party or the failure of any of the same to perform or
comply with any term of this Lease. Any party seeking indemnification in
accordance with the foregoing shall be referred to hereinafter as an
"Indemnified Party". Any Indemnified Party shall use due diligence to give
notice to the other party of the existence of any claim giving rise to the need
for such indemnification within thirty (30) Business Days after the date on
which such Indemnified Party shall have obtained actual knowledge of such claim
(but the failure to provide such notice shall not release any party from its
obligations to indemnify hereunder). In case any action, suit or proceeding is
brought against any Indemnified Party by reason of any occurrence referred to
above, the other party, at its expense, upon the request of such Indemnified
Party, will resist and defend such action, suit or proceeding or cause the same
to be resisted and

                                       8
<PAGE>

defended by counsel designated by the defending party and reasonably acceptable
to such Indemnified Party.

          13. Inspection.  Landlord and its authorized representatives may enter
              ----------
the Property, subject to Tenant's security requirements, at all reasonable times
(provided that no such entry shall be made without forty-eight (48) hours
advance written notice or shall unreasonably interfere with the conduct of
Tenant's business) for the purpose of (a) inspecting the same, (b) exhibiting
the Property for the purpose of sale or mortgage or other financing, (c) at any
time within six (6) months prior to the expiration of the term of this Lease,
exhibiting the Property for the purpose of leasing same, and (d) at any time
after Tenant shall have abandoned the Property and there shall be an Event of
Default in respect of Tenant's rental obligations hereunder, displaying thereon
advertisements for sale or letting. Landlord shall not have any duty to make any
such inspection and shall not incur any liability or obligation for not making
any such inspection. No such entry shall constitute an eviction of Tenant.

          14. Payment of Taxes.  Subject to the provisions of Section 17 hereof,
              ----------------
Tenant will pay, prior to the date when the same would otherwise become
delinquent, all taxes (including, without limitation, real estate taxes,
personal or other property taxes and all sales, value added, gross receipts,
excise, use and similar taxes payable by Landlord to any governmental authority,
but only to the extent arising out of the fact that Landlord owns the Property
and the Property is subject to this Lease (without any effect on the calculation
of any such amount based upon any other real property that Landlord may own or
any other revenues that Landlord may receive), assessments (including, without
limitation, all assessments for public improvements or benefits, whether or not
commenced or completed prior to the date hereof and whether or not to be
completed within the term hereof) installments of which are payable with respect
to time periods during the Lease Term and subsequent to the Rental Commencement
Date, water, sewer or other rents, rates and charges, review, license fees,
permit fees, or any future inspection fees and other authorization fees which
may be created or imposed and other charges, in each case whether general or
special, ordinary or extraordinary, or foreseen or unforeseen, of every
character that may be assessed, levied, confirmed or imposed on or in respect of
the Property or any rent therefrom with respect to the period of time during the
Lease Term, and subsequent to the Rental Commencement Date (all of the foregoing
being hereinafter collectively referred to as "Taxes"). Notwithstanding the
foregoing or any other provision of this Lease, Tenant shall not be required to
pay any income, profits or revenue tax upon the net income of Landlord, nor any
franchise, excise, corporate, estate, inheritance, succession, capital levy or
transfer tax of Landlord, nor any interest, additions to tax or penalties in
respect thereof, unless such tax is imposed, levied or assessed in substitution
for any Taxes that Tenant is required to pay pursuant to this Section 14. Tenant
will furnish to Landlord, upon request, official receipts or other proof
reasonably satisfactory to Landlord evidencing payment of any Taxes in
accordance with the requirements of this Section 14. Landlord agrees not to
consent to the imposition of any future special assessment without obtaining
Tenant's consent thereto.

          15. Compliance with Legal and Insurance Requirements.  Subject to the
              ------------------------------------------------
terms of the Improvement Agreement and the provisions of Sections 6, 7, 16 and
17 hereof, Tenant

                                       9
<PAGE>

at its expense will promptly (a) comply with all Legal Requirements and
Insurance Requirements arising from Tenant's use and occupancy of the Property
on or after the Commencement Date, and (b) procure, maintain and comply with all
permits, licenses and other authorizations required for the use to which the
Property will be put by Tenant on or after the Commencement Date.
Notwithstanding the foregoing to the contrary, Landlord shall be required to
bear, and to pay to Tenant promptly following written demand therefor, that
portion of the cost of any capital improvements which must be made by Tenant to
the Property under the provisions of this Section 15 as follows, if such capital
improvement item shall not be necessary solely as a result of Tenant's
particular use (other than general office use) of the Property. The cost of any
such improvement item shall be prorated over its reasonably estimated useful
life, and the portion that is attributable to the period of time after
expiration of the Lease Term (excluding extensions thereof unless Tenant shall
have previously exercised its extension option pursuant to Section 36 hereof)
shall be borne by Landlord and paid to Tenant promptly following Tenant's
written demand therefor. Prior to incurring any such cost for any capital item,
Tenant shall deliver written notice to Landlord that Tenant is considering
incurring such capital cost, and Tenant shall consult with Landlord before
incurring such cost. The foregoing sentence is a requirement that Tenant consult
with Landlord only, and shall not be understood to provide Landlord with any
approval right over Tenant's incurring any such capital cost.

          16. Mechanic's Liens.  Tenant shall indemnify Landlord with respect to
              ----------------
any liens or encumbrances created by reason of any labor or services performed
for materials used by or furnished to Tenant, or any assignee or sublessee of
Tenant, or any contractor employed by Tenant, or any assignee or sublessee of
Tenant, with respect to the Property or any part thereof. If any lien arising
out of any work performed, materials furnished or obligations incurred by Tenant
(or any such other party) is filed against the Property, within thirty (30) days
following the notice to Tenant of the same Tenant shall cause such lien to be
discharged of record or, if Tenant desires to contest the lien, Tenant shall
post security in an amount sufficient to ensure release of the lien if a final
nonappealable judgment establishing the validity of the lien is entered at a
later date.

          17. Permitted Contests.  Tenant at its expense may contest by
              ------------------
appropriate legal proceedings conducted in good faith and with due diligence,
the amount or validity or application, in whole or in part, of any Taxes or lien
therefor or any Legal Requirement or Insurance Requirement or the application of
any instrument of record affecting the Property or any part thereof, provided
that Tenant shall first have either (i) paid the disputed amount under protest,
or (ii) furnished to Landlord such security as Landlord may deem reasonably
necessary to insure the ultimate payment of the contested amount and to prevent
the forfeiture of the Property or any sums payable to Landlord or any Mortgagee
hereunder, or the accrual of penalties and interest to the extent not paid
directly by Tenant. Tenant shall give prompt written notice to Landlord of the
commencement of any contest referred to in the preceding sentence, providing a
reasonably detailed description thereof, and Landlord shall, at Tenant's
expense, cooperate with Tenant with respect to any such contest. Subject to the
last sentence of this Section 17, Tenant shall indemnify and save Landlord and
any Mortgagee harmless from and against any and all losses, judgments, decrees
and costs (including, without limitation,

                                       10
<PAGE>

reasonable attorneys' fees and expenses) incurred in connection therewith.
Tenant agrees that it will, promptly after final determination of each such
contest, fully. pay and discharge the amounts which shall finally be levied,
assessed, charged or imposed or determined to be payable, together with all
penalties, fines, interest, costs and expenses incurred in connection therewith,
and perform all acts the performance of which shall be finally ordered or
decreed as a result thereof. Nothing in this Section 17 shall be interpreted to
require Tenant to contest or protest any matters. In addition, notwithstanding
the foregoing to the contrary, Tenant shall not be obligated to pay any judgment
with respect to any matter for which Landlord would otherwise be liable under
this Lease without such contest or protest.

           18. Insurance.
               ---------

               18.1   Risks to be Insured.  Tenant, at its expense, will
                      -------------------
maintain with insurers authorized to issue insurance in the State of Arizona and
having an A.M. Best rating of "B+" or better or otherwise approved by Landlord
and any Mortgagee (a) insurance with respect to the Improvements against loss or
damage by fire, lightning and other risks from time to time included under "all-
risk" policies and against loss or damage by sprinkler leakage, water damage,
collapse, vandalism and malicious mischief and in an amount equal to 100% of the
actual replacement cost of the Improvements (initially determined as of the date
on which such insurance is originally issued, and subsequently re-determined on
the basis on an annual review of the actual replacement cost of the Improvement)
(such insurance shall also include at least nine (9) months rental loss
coverage), (b) comprehensive general liability insurance against claims arising
out of or connected with the possession, use, leasing, operation or occupancy of
the Property in with a combined single limit coverage of not less than
$5,000,000 for any single injury to a person and $10,000,000 for all claims with
respect to property damage and personal injury and death with respect to any one
occurrence, provided that Landlord shall have the right to require Tenant to
increase the amount of coverage of such liability insurance to the amount
reasonably necessary to bring such coverage into conformity with the level of
coverage commonly carried by similar properties in Scottsdale, which right
Landlord may exercise no more frequently than once every five (5) years, (c)
explosion insurance in respect of any steam and pressure boilers and similar
apparatus located on the Property in amounts not less than those required by
subdivision (b) above, and (d) in the event that the Property shall at any time
be used as anything other than for general office purposes, such other insurance
against such risks and in such amounts as Landlord shall reasonably request.
Notwithstanding the foregoing to the contrary, Tenant may self-insure with
respect to workers' compensation insurance to the extent permitted by the State
of Arizona, and any or all insurance required under this Section 18.1 may be
effected under one or more blanket policy or policies covering the Property and
other property and assets not constituting part of the Property, provided,
however, that any such blanket policy or policies shall specify the portion of
the total coverage of such policy or policies that is allocated to the Property
and shall, in all other respects, comply with the requirements of this Section
18.

               18.2   Policy Provisions.  All insurance maintained by Tenant
                      -----------------
pursuant to Section 18.1 hereof shall (a) name Landlord, Tenant and any
Mortgagee as insured parties,

                                       11
<PAGE>

(b) provide that all insurance proceeds for losses of less than $300,000 shall
(except in the case of comprehensive general liability insurance and workers'
compensation insurance) be adjusted by and be payable to Tenant to be used by
Tenant, to the extent necessary, for Restoration, (c) provide that all insurance
proceeds for losses of $300,000 or more shall (except in the case of
comprehensive general liability insurance and workers' compensation insurance)
be adjusted by Landlord and Tenant jointly and shall be payable to any Mortgagee
by means of a standard mortgagee loss payable endorsement if so required by such
Mortgagee (or to Landlord, if there is no Mortgagee), to be held in trust
pursuant to the terms of this Lease, and (d) provide that if all or any part of
such policy is canceled, terminated or expires, the insurer will forthwith give
notice thereof to each named insured party and loss payee and that no
cancellation, reduction in amount or material reduction in coverage thereof
shall be effective until at least 30 days after delivery to each named insured
party and loss payee of written notice thereof.

               18.3   Delivery of Policies; Insurance Certificates.  Tenant
                      --------------------------------------------
will deliver to Landlord and any Mortgagee certified copies of the originals of
all insurance policies or certificates thereof, and any amendments or
supplements thereto, with respect to the Property that Tenant is required to
maintain pursuant to this Section 18, together with evidence as to the payment
of all premiums then due thereon, and not later than 10 days prior to the
expiration of any policy, a certificate of the insurer evidencing the
replacement or renewal thereof.

               18.4   Mutual Waiver of Insurable Claims.  Notwithstanding
                      ---------------------------------
anything contained herein to the contrary, Tenant and Landlord hereby mutually
release each other and each other's agents and employees from any liability for
loss or damage by fire or other casualty coverable by the types of insurance
required to be maintained under this Lease or otherwise in force at the time of
such loss or damage, whether or not the loss or damage resulted from negligence.

          19.  Hazardous Materials.
               -------------------

               19.1   Definitions.  As used herein, the term "Hazardous
                      -----------
Materials" shall mean any substance: (i) the presence of which requires
investigation or remediation under any federal, state or local statute,

insulation; or (vii) without limitation radon gas.

               19.2   Warranties and Obligations.  Landlord hereby warrants that
                      --------------------------
neither Landlord, nor, to Landlord's actual knowledge without investigation, any
third party, has used, manufactured, generated, treated, stored, disposed of, or
released any Hazardous Material on, under or about the Property or real estate
in the vicinity of the Property or transported any Hazardous Material over the
Property and that neither Landlord nor, to Landlord's actual knowledge without
investigation, any third party has installed, used or removed any storage tank
on, from or in connection with the Property, and to Landlord's actual knowledge
without investigation, there are no storage tanks or wells (whether exiting or
abandoned) located on, under or about the Property and that no Hazardous
Materials have been incorporated into the construction of the Improvements.
Landlord, at its sole cost, shall comply with all Legal Requirements which
impose liability or responsibility upon either Landlord or Tenant to
investigate, remediate or otherwise take any action with respect to any
Hazardous Materials existing in, or under or about the Property as of the date
of delivery of possession to Tenant. Landlord shall defend, protect, hold
harmless and indemnify Tenant and Tenant's Agents with respect to all actions or
claims by federal, state, and local governmental agencies or by other third
parties for fines, penalties, fees (including, but not limited to, reasonable
attorneys' and consultants' fees), costs, damages, liabilities, losses,
remediation costs, investigation costs, response costs and other expenses
arising out of, resulting from, or caused by a condition which is a violation of
any of the foregoing warranties or Landlord's failure to perform the foregoing
obligations in this Section 19.2 or the introduction onto the Property by
Landlord or Landlord's Agents of any Hazardous Materials. In addition to the
foregoing remedies, if, under applicable Legal Requirements, Tenant is prevented
from occupying or using all or any portion of the Improvements due to the
subsequently found presence or removal of any Hazardous Materials on or from the
Improvements, Basic Rent and Additional Rent shall be abated during the period
between the date of such discovery and the date such discovered Hazardous
Materials are fully removed from the Improvements in proportion to the degree to
which Tenant's occupancy or use of the Property is so prevented by such presence
or removal or such Hazardous Materials. Tenant shall not release or authorize
any other party to release any Hazardous Materials upon, above or beneath the
Property for any purpose, except for customary quantities of office and
janitorial supplies used for customary purposes which may, technically, fall

comply with all Legal Requirements which impose liability or responsibility upon
either Landlord or Tenant to investigate, remediate or otherwise take any action
with respect to any Hazardous Materials that Tenant, or any other party acting
at Tenant's direction, or any assignee or sublessee of Tenant, causes to be
released upon the Property in violation of applicable Legal Requirements
pertaining to Hazardous Materials or which requires remediation under applicable
Legal Requirements. Tenant shall defend, protect, hold harmless and indemnify
Landlord and Landlord's Agents with respect to all actions or claims by federal,
state, and local governmental agencies or by other third parties for fines,
penalties, fees (including, but not limited to, reasonable attorneys' and
consultants' fees), costs, damages, liabilities, losses, remediation costs,
investigation costs, response costs

                                       13
<PAGE>

and other expenses arising out of, resulting from, or caused by the introduction
of any Hazardous Materials onto the Property by Tenant or Tenant's Agents.

               19.3   Provisions Survive Termination.  The provisions of this
                      ------------------------------
Section 19 shall survive the expiration or termination of this Lease or Tenant's
non-occupancy of the Property notwithstanding the continuation of this Lease.

               19.4   Controlling Provisions.  The provisions of this Section 19
                      ----------------------
are intended to govern the rights and liabilities of Landlord and Tenant with

Lease that might otherwise be deemed applicable. The provisions of this Section
19 shall be controlling with respect to any provisions in this Lease that are
inconsistent with this Section 19.

                      ---------------------
destruction of the Improvements located on the Property (or any part of such
Improvements), the Restoration of which is reasonably estimated to cost more
than $10,000.00, Tenant will promptly give notice thereof to Landlord, generally
describing the nature and extent of such damage or destruction and setting forth
Tenant's best estimate of the cost of Restoration.

               20.2   Restoration.  Except as provided below, in case of any

damage to or destruction of the Improvements located on the Property, Landlord,
whether or not the insurance proceeds, if any, on account of such damage or
destruction shall be sufficient for the purpose (but provided that Tenant in
fact carries the policy or policies of insurance required to be carried by
Tenant under the provisions of Section 18.l(a) of this Lease and makes any
proceeds thereof available to Landlord for the purpose of such Restoration),
will promptly commence and diligently prosecute to completion Restoration of
such Improvements.

               20.3   Total Destruction.  In case of (a) the destruction during
                      -----------------
the last year of the Lease Term of all of the Improvements located on the
Property, or (b) the destruction during the last year of the Lease Term, if the
cost of Restoration exceeds seventy percent (70%) of the then actual replacement
cost of the Improvements (any such destruction being hereinafter referred to as
a "Total Destruction"), Landlord may, by notice to Tenant given within 60 days
after the date of such destruction, terminate this Lease, provided any such
termination by Landlord shall be effective only if Landlord does not within the
two hundred forty (240) day period following such date of damage or destruction
enter into any discussions or negotiations with respect to any rebuilding on the
Parcels or with any prospective tenants on the Parcels, and further provided
that Landlord may not terminate this Lease pursuant to this Section 20.3 if
Tenant, at the time of such damage, has an express written option to further
extend the term of this Lease and Tenant exercises such option to so further
extend the Lease Term within thirty (30) days following the date of Landlord's
termination notice.

               20.4   Tenant's Right to Terminate.  If the Improvements are
                      ---------------------------
damaged by any peril and Landlord elects not to terminate this Lease pursuant to
Section 20.3, then as soon as reasonably practicable, Landlord shall furnish
Tenant with the written opinion of Landlord's architect or construction
consultant as to when the Restoration work required of Landlord may be
completed.  Tenant shall have the option to terminate this Lease in the event
any of the following occurs, which option. may be exercised only by delivery to

with respect to (c) and (d) below:

                      (a)  The Improvements are damaged by any peril and the
Restoration of the Improvements reasonably cannot be substantially completed
within one hundred eighty (180) days after the date of damage or destruction.

                      (b)  The Improvements are damaged by any peril within two
(2) years of the last day of the Lease Term and the Restoration of the
Improvements reasonably cannot be substantially completed within ninety (90)
days after the date of such damage.

substantially completed within two hundred forty (240) days after the date of
the damage or destruction.

Improvements within thirty (30) days following the receipt of insurance
proceeds.

               20.5   Abatement of Rent.  In the event of damage to the
                      -----------------
Property, the Basic Rent and Additional Rent shall be temporarily abated during
the period between the date of damage and the date of Restoration of the
Improvements in proportion to the degree to which Tenant's use of the Property
is impaired by such damage.

               20.6   Application of Insurance Proceeds.  Tenant hereby
                      ---------------------------------
irrevocably assigns to Landlord any insurance proceeds to which Tenant may

Improvements or any part thereof is damaged or destroyed by fire or other
casualty. Any insurance payment of more than $300,000 shall be paid to and held
in trust in an interest bearing account and disbursed to pay the-costs of
Restoration in accordance with customary procedures by Mortgagee or, if there is
no Mortgagee or if Mortgagee does not require that it hold such compensation, by
Landlord (to be held in trust pursuant to the terms of this Lease); provided,
however, that any such insurance proceeds which is not in excess of $300,000

               20.7   Waiver of Statutory Provisions.  Landlord and Tenant
                      ------------------------------
hereby waive any statutory provisions pertaining to rights of rental abatement
or lease termination in the event of damage or destruction of real property
subject to a lease, to the extent that any such provisions are contrary to those
contained in this Section 20, and Landlord and Tenant agree that the provisions
of this Section 20 shall control in the event of any such damage or destruction
on or to any portion of the Property.

               ------------------

               21.1   Tenant to Give Notice.  In case of a Taking, or the
                      ---------------------
commencement of any proceedings or negotiations that might result in a Taking,
in respect of which the Restoration of the Property is reasonably estimated to
cost more than $10,000, Tenant will promptly give notice thereof to Landlord,
generally describing the nature and extent of such Taking or the nature of such
proceedings or negotiations and the nature and extent of the Taking that might
result therefrom.

               21.2   Partial Taking.  In the case of a Taking other than a

Property is impaired by such Partial Taking, and (c) Tenant shall receive from
the Award the portions of the Award attributable to Tenant's Equipment and the
unamortized value of all alterations, additions or improvements to the Property
paid for by Tenant (other than from the Improvement Allowance, as defined in the
Improvement Agreement) and located in the part of the Property taken by the
Partial Taking (but not any amount attributable to the value of Tenant's
leasehold estate) and Landlord shall receive from the Award those portions
thereof applicable to the Parcels and the unamortized value of the Improvements
and other improvements paid for by Landlord (including, without limitation, from
the Improvement Allowance) (with all such unamortized values to be determined
based on the useful life of the particular improvement), and (d) Landlord,
whether or not the Awards shall be sufficient for the purpose, at its expense
will promptly commence and diligently prosecute to completion Restoration of the
Property (including, without limitation, restoration of the Improvements to an
architecturally whole unit, to the extent practicable), except for any reduction
in area of the Property caused by such Taking; provided, however, that in case
of Taking for temporary use ("temporary use" being defined for all purposes
herein as any taking for less than nine consecutive months) Landlord shall not
be required to effect any Restoration until such Taking is terminated.

               21.3   Total Taking.  In case of the Taking during the Lease
                      ------------
Term of the Property in its entirety (or all of the Improvements located
thereon) or the Taking during the Lease Term (other than for temporary use) of
such a substantial part of the Property (or the Improvements located thereon)
that, in the sole good faith judgment of Tenant, either (a) the portion of the
Property (or the Improvements located thereon) remaining after such Taking is
(and after Restoration would be) unsuitable for use by Tenant in the operation
of its business,

                                       16
<PAGE>

or (b) Restoration of the Property (or the Improvements located thereon) is not
economically feasible (any such Taking being hereinafter referred to as a "Total
Taking"), this Lease shall terminate as of the date of such Total Taking and
Tenant shall receive from the Award those portions of the Award attributable to
Tenant's Equipment, the unamortized value of all alterations, additions or
improvements to the Property paid for by Tenant (other than from the Improvement
Allowance), loss of Tenant's good will and moving expenses of Tenant (but not
any amount attributable to the value of Tenant's leasehold estate) and Landlord
shall receive from the Award those portions thereof applicable to the Parcels
and the unamortized value of the Improvements and other improvements paid for by
Landlord (including, without limitation, from the Improvement Allowance) (with
such all unamortized values to be determined based on the useful life of the
particular improvement).

               21.4   Application of Awards.  The parties agree that in the
                      ---------------------
event of a Taking, all rights between them in and to an Award shall be as set
forth herein.  Each party agrees that each shall make separate claims for an
Award from the condemning Person.

                      ------------------------------
Landlord within fifteen (15 ) business days following Landlord's written request
therefor (but in no event more often than three times in any twelve-month
period) (a) an Estoppel Certificate of Tenant stating (i) that this Lease is
unmodified and in full force and effect (or, if there have been modifications,
that this Lease is in full force and effect, as modified, and stating the
modifications), (ii) the date to which the Basic Rent has been paid and that all
Additional Rent payable on or before the date of such Estoppel Certificate has
been paid, or if any Additional Rent has not been paid, specifying the nature of
such non-payment, and (iii) that no Event of Default exists hereunder, or, if
any such Event of Default exists, specifying the nature and period of existence
thereof and what action Tenant is taking or has taken with respect thereto, and
(b) such information with respect to the Lease as from time to time may
reasonably be requested.

               22.2   Estoppel Certificate of Landlord. Within fifteen (15) days
                      --------------------------------
following Tenant's written request therefor, but in no event more often than
three times in any twelve-month period (which request shall (i) state that it is
made pursuant to this Section 22.2 and, if applicable, that Tenant proposes,
pursuant to Section 24.1 hereof, to assign its interest in this Lease or sublet
a portion of the Property to a Person identified in such request, and (ii) be
accompanied by a copy of this Lease and each modification hereof or amendment
hereto, if any, to and including the date of such request) Landlord will deliver

unmodified and in full force and effect (or, if there have been modifications,
that this Lease is in full force and effect, as modified, and stating the
modifications), (b) the date to which Basic Rent and Additional Rent have been
paid hereunder and (c) whether or not an Event of Default exists hereunder and,

that) no rights or remedies of Landlord hereunder or

                                       17
<PAGE>

otherwise resulting from any condition, event or circumstance that would, with
the giving of notice and/or the passing of time, result in an Event of Default
hereunder shall be waived, impaired or diminished in any respect by reason of
any such Estoppel Certificate or any statement made therein. No failure of
Landlord to deliver any such Estoppel Certificate shall release, discharge or
otherwise affect any of Tenant's or Landlord's rights or obligations hereunder.

               22.3   Financial Statements.  The provisions of this Section 22.3
                      --------------------
shall not apply at any time that Tenant hereunder is a company subject to
reporting requirements under the Securities Exchange Act of 1934, as amended. If
any potential purchaser of the Property, Mortgagee or purchaser of an interest
in Landlord, as part of its good faith diligence review of the Property, desires
to review any financial statements of Tenant, Landlord shall so notify Tenant in
writing. Such writing shall include a written undertaking from such potential
purchaser or Mortgagee to keep such financial statements and the information
contained therein in confidence, and to return such financial statements, and
all copies of such statements and any information extracted therefrom, to Tenant
promptly following such party's analysis thereof. Within fifteen (15) days
following Tenant's receipt of such written request from Landlord and such
written undertaking signed by the party to whom such financial statements would
be delivered, Tenant shall deliver directly to such potential purchaser or
Mortgagee its most recently prepared balance sheet and income statement, if any
exists. Tenant shall have no obligation to prepare any balance sheet or
financial statement in response to any such request.

               ----------------------------------------------------
shall fail to make any payment or perform any act required to be made or
performed by it hereunder, Landlord, upon thirty (30) days prior written notice
(unless a longer period is reasonably required by Tenant to perform the act in
question, in which event Tenant shall be permitted such longer period of time to
perform such act, so long as Tenant commences to perform such act within such
thirty-day period and thereafter diligently prosecutes the same to completion)
to Tenant (except in cases of emergency that threaten bodily injury or material
property damage), but without waiving or releasing any obligation or default,
may make such payment or perform such act for the account and at the expense of
Tenant, and may enter upon the Property or any part thereof for such purpose and
take all such action thereon as, in the reasonable opinion of Landlord, may be
necessary or appropriate therefor. No such entry shall constitute an eviction of
Tenant. All reasonable payments so made by Landlord and all reasonable costs and
expenses (including, without limitation, attorneys' fees and expenses) incurred
in connection therewith or in connection with the performance by Landlord of any
such act shall constitute Additional Rent hereunder.

          24.  Assignments, Subleases, Mortgages.
               ---------------------------------

               24.1   Assignments and Subleases by Tenant.  If no Event of
                      -----------------------------------
Default shall have occurred and be continuing, Tenant may, after obtaining the
prior written consent of Landlord, not to be unreasonably withheld or delayed,
at any time and from time to time sublet the Property or any part thereof, and
may assign its interest in this Lease; provided however, that Tenant may,
without Landlord's prior written consent, assign its interest in the Lease or
sublet the Property or a portion thereof to (i) a related entity parent company,
subsidiary, affiliate, division or corporation controlled by or under common
control with Tenant; (ii) a successor corporation related to Tenant by merger,
consolidation, non-bankruptcy reorganization or government action; or (iii) a
purchaser of substantially all of the Tenant's assets; and further provided,
however, that (a) Tenant shall, in all cases, deliver to Landlord a fully
executed counterpart of each such sublease or assignment promptly after
execution thereof, and (b) no assignment, whether by operation of law,
consolidation, merger, a sale of stock or otherwise, shall be effective prior to
the execution by the assignee and delivery to Landlord of an instrument,
reasonably satisfactory in form and substance to Landlord, assuming all of the
obligations of Tenant under this Lease. No assignment or sublease made as
permitted by this Section 24.1 shall affect or reduce any obligations of Tenant
or any rights of Landlord hereunder, and all obligations of the Tenant
originally named hereunder shall continue in full force and effect as the
obligations of a principal and not of a guarantor or surety, to the same extent
as though no assignment or subletting had been made.

               24.2   Assignments and Mortgages by Landlord.  The interest of
                      -------------------------------------
Landlord in this Lease and in and to the Property or any part thereof may, at
any time and from time to time, be sold, conveyed, assigned or otherwise
transferred, without the prior written consent of Tenant, and upon any sale or
conveyance of the Property as an entirety or any assignment or other transfer
(other than for the purpose of securing indebtedness) by any party lessor of its
interest in this Lease and in and to the Property, such party lessor shall be
completely relieved of and from any and all obligations not theretofore accrued
under this Lease or otherwise with respect to the Property, and such party
lessor shall have no further obligations whatsoever to any party lessee,
provided that any funds in the hands of Landlord or the then grantor at the time
of such transfer that were deposited by Tenant, and in which Tenant has an
interest, shall be turned over to the grantee and Tenant receives a copy of a
written assumption agreement whereby the transferee assumes the obligations of
Landlord under this Lease to be performed after the date of such transfer or
conveyance, except to the extent that any such obligation accrued prior to the
date of such sale, conveyance, assignment or transfer, and Tenant shall
thereupon look only to the then owner of Landlord's estate in the Property for
the performance of any obligations of Landlord hereunder. Landlord may also from
time to time mortgage or assign, by way of pledge or otherwise, any or all of
the rights, in whole or in part, of Landlord under this Lease to any Person as
security for the indebtedness or other obligations of Landlord. From and after
any such mortgage or assignment and to the extent provided in the instrument
effecting such mortgage or assignment, (a) such Mortgagee may enforce any and
all of the terms of this Lease to the extent so assigned as though such
Mortgagee had been a party hereto, (b) no action or failure to act on the part
of Landlord shall adversely affect or limit any rights of such

                                       19
<PAGE>

Mortgagee provided that, (c) no such assignment shall constitute an assumption
of any such obligations on the part of such Mortgagee, and (d) a copy of all
notices, demands, consents, approvals and other instruments given by Tenant
hereunder shall also be delivered to such Mortgagee, if such Mortgagee shall
have provided Tenant with written notice of its address for such purposes.
Notwithstanding the foregoing provisions in this Section 24, the parties agree
that the foregoing provisions shall not be interpreted to limit any of Tenant's
rights otherwise available under this Lease, including any offset rights or
termination rights that are expressly provided under the terms of this Lease.

          25.  Events of Default; Termination.  If any one or more of the
               ------------------------------
following events ("Events of Default") shall occur (whatever the reason
therefor, and whether voluntary or involuntary or by operation of law or
pursuant to or in compliance with any judgment, decree or order of any court of
any rule or regulation of any administrative or governmental body):

               (a)  if Tenant shall fail to pay any installment of Basic Rent or
Additional Rent, or other sum required to be paid by Tenant hereunder on the
date the same becomes due and payable and such failure continues for more than
five (5) Business Days after written notice thereof is given to Tenant; or

               (b)  if Tenant shall fail to perform or comply with any term of
this Lease (other than those referred to in clause (a) above) or any term of any
instrument related hereto pursuant to which Tenant undertakes obligations or
makes agreements for the benefit of Landlord or any Mortgagee and, in any such
case, such failure shall continue for more than 30 days after Tenant receives
written notice from Landlord; provided, however, that in the case of any such
failure that is susceptible of being cured but that cannot with diligence be
cured within such 30-day period, if Tenant shall promptly commence to cure the
same and shall thereafter prosecute the curing thereof with diligence, the
period within which such failure may be cured shall be extended for such further
period as shall be necessary for the curing thereof with diligence; or

               (c)  if Tenant shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to
itself or its debts under any bankruptcy, insolvency or other similar law now or
hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of it or any substantial part of
its property, or shall consent to any such relief or to the appointment of or
taking possession by any such official in an involuntary case or other
proceeding commenced against it, or shall make a general assignment for the
benefit of creditors, or shall take any corporate action to authorize any of the
foregoing; or

               (d)  if an involuntary case or other proceeding shall be
commenced against Tenant seeking liquidation, reorganization or other relief
with respect to it or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any
substantial part of its property, and such involuntary case or other proceeding
shall remain

                                       20
<PAGE>

undischarged and unstayed for a period of 90 days, or if an order for relief
shall be entered against Tenant under the federal bankruptcy laws as now or
hereafter in effect which is not fully stayed within seven (7) business days
after the entry thereof;

then, and in any such event, Landlord may at any time thereafter, during the
continuance of any such Event of Default, give a written termination notice to
Tenant specifying a date (not less than five days from the date on which such
notice is given) on which this Lease shall terminate, and, on such date, the
term of this Lease shall terminate and all rights of Tenant under this lease
shall cease. All reasonable costs and expenses incurred by or on behalf of
Landlord (including, without limitation, reasonable attorneys' fees and
expenses) occasioned by and following any Event of Default by Tenant under this
Lease shall constitute Additional Rent hereunder.

          26.  Remedies. Upon the occurrence of an Event of Default, prior to
               --------
the cure thereof, Landlord shall have the following remedies, to which Landlord
may resort in the alternative:

                    (i)       Landlord may continue this Lease in full force
and effect, and this Lease shall continue in full force and effect as long as
Landlord does not terminate this Lease, and Landlord shall have the right to
collect Basic Rent and Additional Rent when due. During the continuation of such
Event of Default, Landlord may enter the Property and relet it, or any part of
it, to third parties for Tenant's account, to be set off against amounts owing
from Tenant to Landlord hereunder, with any surplus to be delivered to Tenant at
the end of the Lease Term. Tenant shall be liable to Landlord for all costs
Landlord incurs in reletting the Property or any part thereof, including,
without limitation, reasonable broker's commissions, expenses of cleaning and
redecorating the Property required by the reletting and like costs. No act by
Landlord other than giving written notice to Tenant shall terminate this Lease.

                    (ii)      Landlord may by written notice terminate Tenant's
right to possession of the Property at any time and relet the Property or any
part thereof Acts of maintenance, efforts to relet the Property or the
appointment of a receiver on Landlord's initiative to protect Landlord's
interest under this Lease shall not constitute a termination of Tenant's right
to possession. On termination, Landlord has the right to remove all of Tenant's
personal property and store same at Tenant's cost and to recover from Tenant:

                              (a)  the worth at the time of award of the unpaid
Basic Rent and Additional Rent which had been earned at the time of termination
including interest at the Interest Rate;

                              (b)  the worth at the time of award of the amount
by which the unpaid Basic Rent and Additional Rent which would have been earned
after termination until the time of award exceeds the amount of such rental loss
that Tenant proves could have been reasonably avoided, including interest at the
Interest Rate;

                                       21
<PAGE>

                              (c)  the worth at the time of award of the amount
by which unpaid Basic Rent and Additional Rent for the balance of the term after
the time of award exceeds the amount of such rental loss for the same period
that Tenant proves could be reasonably avoided, discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award
plus one percent (1%);

                              (d)  any other amount necessary to compensate
Landlord for all the detriment proximately caused by Tenant's failure to perform
its obligations under this Lease or which in the ordinary course of things would
be likely to result therefrom; and

                              (e)  as used in subparagraphs (a) through (c)
above, the term "time of award" shall mean the date of entry of a judgment or
award against Tenant in an action or proceeding arising out of Tenant's Event of
Default.

          Tenant waives redemption or relief from forfeiture under any other
present or future law, in the event Tenant is evicted or Landlord takes
possession of the Property by reason of any Event of Default of Tenant
hereunder.

          27.  [INTENTIONALLY OMITTED]

          28.  No Waiver. No failure by Landlord or Tenant to insist upon
               ---------
the strict performance of any term hereof or to exercise any right, power or
remedy consequent upon a breach thereof, and no acceptance of full or partial
rent during the continuance of any such breach, shall constitute a waiver of any
such breach or of any such term. No waiver of any breach shall affect or alter
this Lease, which shall continue in full force and effect, or the rights of
Landlord or Tenant with respect to any other then existing or subsequent breach.
No foreclosure, sale or other proceedings under any mortgage or other security
arrangement with respect to the Property shall discharge or otherwise affect the
obligations of Tenant hereunder.

          29.  Remedies Cumulative. Each right, power and remedy of
               -------------------
Landlord or Tenant provided for in this Lease or now or hereafter existing at
law or in equity or by statute or otherwise shall be cumulative and concurrent
and shall be in addition to every other right, power or remedy provided for in
this Lease or now or hereafter existing at law or in equity or by statute or
otherwise, and the exercise or attempted exercise by Landlord or Tenant of any
one or more of the rights, powers or remedies provided for in this Lease or now
or hereafter existing at law or in equity or by statute or otherwise shall not
preclude the simultaneous or later exercise by Landlord or Tenant of any or all
such other rights, powers or remedies.

          30.  [INTENTIONALLY OMITTED]

          31.  Surrender. Upon the expiration or earlier termination of this
               ---------
Lease, Tenant, at its expense, shall quit and surrender to Landlord the Property
in good order and condition, ordinary wear and tear, damage by casualty and
repair and maintenance obligations for which Landlord is responsible under this
Lease excepted and, if requested by Landlord, shall

                                       22
<PAGE>

remove therefrom, at Tenant's expense, all of Tenant's Equipment which is not
affixed to the Property and shall repair, at Tenant's expense, all damage caused
by such removal.

          32.  Notices.  All notices, offers, acceptances, rejections, consents
               -------
and other communications hereunder shall be in writing and shall be sent by
certified mail, postage prepaid, return receipt requested, or by a nationally
recognized overnight courier service, or by telecopy with an original by regular

memorandum of this Lease, including the extension options provided in Section 36
of this Lease and the right of first offer provided in Section 38 of this Lease,
satisfactory in form and substance to Landlord and Tenant, for recording in the

          34.  Quiet Enjoyment.  So long as Tenant shall pay the Basic Rent and
               ---------------
Additional Rent and any other sums payable hereunder as the same become due and
shall fully comply with all of the terms of this Lease and fully perform its
obligations hereunder, Tenant (and any subtenant of Tenant permitted pursuant to

Notwithstanding anything contained in this Lease to the contrary, it is
specifically understood and agreed that neither Landlord nor any beneficiary of
Landlord, nor any officer, director or shareholder of any of the foregoing, or

Section 34 shall prohibit Landlord, or any Mortgagee, or their respective
authorized representatives, from entering the Property at reasonable times to
inspect the same in accordance with the provisions of Section 13 hereof.

          35.  Miscellaneous.  All rights, powers and remedies provided
               -------------
herein may be exercised only to the extent that the exercise thereof does not
violate any applicable provision of any Legal Requirement, and are intended to
be limited to the extent necessary so that they will not render this Lease
invalid, illegal or unenforceable under the provisions of any applicable Legal
Requirement. If any term of this Lease or any application thereof shall be
invalid or unenforceable, the remainder of this Lease and any other application
of such term shall not be affected thereby. This Lease may be changed, waived,
discharged or terminated only by an instrument in writing, signed by each of the
parties hereto. Subject to Section 24 hereof, this Lease shall be binding upon
and inure to the benefit of and be enforceable by the respective successors and
permitted assigns of the parties hereto. This Lease shall be construed and
enforced in accordance with and governed by the laws of the State of Arizona.
The headings in this lease are for the purposes of reference only and shall not
limit or otherwise affect the meaning hereof. This Lease may be executed in
several counterparts, each of which shall be an original, but all of which
together shall constitute one and the same instrument.

          36.  Option to Extend.
               ----------------

               36.1  Exercise of Option. Provided that no uncured Event of
                     ------------------
Default shall exist under this Lease at the time of exercise of the hereinafter
described options, Tenant shall have two (2) options to extend the term of this
Lease, each for a period of five (5) years

                                       24
<PAGE>

("Option Term(s)"). Said options shall be exercised only by written notice
delivered to Landlord not later than six (6) months prior to the expiration date
of the then existing term of this Lease. In all respects, the terms, covenants
and conditions of this Lease shall remain unchanged during each of the Option
Terms, except that the Basic Rent payable during each Option Term shall be
revised in accordance with Section 36.2 below, and except that there shall be no
further option to extend the term of this Lease at the end of the second Option
Term.

               36.2  Option Term Rent.  The Basic Rent payable during each of
                     ----------------
the Option Terms shall be ninety-five percent (95%) of the Fair Market Rent as
defined in Section 36.3 below for the Property for the Option Term in question.

               36.3  Fair Market Rent.  For the purposes of this Section 36, the
                     ----------------
term "Fair Market Rent" shall mean the going market rental and any adjustment or
adjustments to such rental at such time(s) in such amount or using such formula
as is prevailing at the time of the commencement of the Option Term in question,
for comparably equipped second generation office space in buildings containing
comparable square feet, located within the immediate area of the Property, and
in a condition comparable to the then existing condition of the Property, taking
into account all legal uses for which the Property could be used without
material alteration thereto and the value of all Improvements and other
improvements on the Property paid for by Landlord for a tenant proposing to sign
a lease for a similar term and having financial qualifications similar to Tenant
and using as a guide equivalent space of similar size, age, construction,
quality and location. There shall be excluded from any determination of "Fair
Market Rent" the rental value attributable to any improvements or alterations
constructed by Tenant with its own funds (other than from the Improvement
Allowance). Any determination of "Fair Market Rent" shall take into account
rental concessions and other economic inducements then prevailing in the market.
Also, if there is no leasing commission payable by Landlord in connection with
Tenant's exercise of an option to extend, then There shall be excluded from any
determination of "Fair Market Rent" the rental value attributable to a standard
leasing commission customarily paid by a lessor in connection with a five (5)
year lease amortized on a straight line basis over the five (5) year Option Term
in question.

               36.4  Appraisal. Promptly following exercise of any option to
                     ---------
extend, the parties shall meet and endeavor to agree upon the Fair Market Rent
of the Property for the Option Term in question. If within thirty (30) days
after exercise of the option, the parties cannot agree upon the Fair Market
Rent, the parties shall submit the matter to binding appraisal in accordance
with the following procedure: Within thirty (30) days after exercise of the
option, the parties shall either (1) jointly appoint an appraiser for this
purpose or (2) failing this joint action, separately designate a disinterested
appraiser. No person shall be appointed or designated an appraiser unless he or
she has at least five (5) years experience in appraising major commercial
property in Maricopa County and is a member of a recognized society of real
estate appraisers. If, within thirty (30) days after their appointment, the two
appraisers reach agreement on the Fair Market Rent, that value shall be binding
and conclusive upon the parties. If the two appraisers thus appointed cannot
reach agreement on the question presented within thirty (30) days after their
appointment, then the appraisers thus appointed shall appoint a third

                                       25
<PAGE>

disinterested appraiser having like qualifications. Within thirty (30) days
after the appointment of the third appraiser, the two appraisers appointed by
the parties shall each submit to the third appraiser and to the parties their
independent appraisal of the Fair Market Rent of the Property for the Option
Term in question. Within thirty (30) days after receipt of the two independent
appraisals, the third appraiser shall select one of the two appraisals submitted
by the two appraisers appointed by the parties as the appraisal closest to the
Fair Market Rent of the Property. The appraisal of the Fair Market Rent so
selected by the third appraiser shall be binding and conclusive upon the
parties. Each party shall pay the fees and expenses of the appraiser appointed
by it and shall share equally the fees and expenses of the third appraiser. If
the two appraisers appointed by the parties cannot agree on the appointment of
the third appraiser, they or either of them shall give notice of such failure to
agree to the parties and if the parties fail to agree upon the selection of such
third appraiser within ten (10) days after the appraisers appointed by the
parties give such notice, then either of the parties, upon notice to the other
party may request such appointment by the American Arbitration Association, or
on its failure, refusal or inability to act, may apply for such appointment to
the presiding judge of the Superior Court of Maricopa County, Arizona.

          37.  Reasonable Approval Standard.  Whenever in this Lease the
               ----------------------------
review, acceptance, approval or consent of either Landlord or Tenant ("Reviewing
Party") is required or desired for the taking of or refraining from taking any
action under the Lease, or to the manner of performing or observing any covenant
or condition of the Lease (collectively "Matter"), the favorable review,
acceptance, approval or consent (collectively "Approval") as to any such Matter
shall neither be unreasonably withheld nor unduly delayed by the Reviewing
Party, and if the Reviewing Part desires to deny or withhold its Approval as to
any such matter, the Reviewing Party shall, by written notice to the other party
given within the time period for the giving of such Approval as provided herein
or elsewhere in this Lease, state with particularity the basis for the denial or
withholding by such Reviewing Party of such Approval. Provided the request made
of the Reviewing Party for the Approval references this Section 37 and indicates
to the effect that a lack of an appropriate response within thirty (30) days (or
within such other period of time for response if the Lease otherwise expressly
provides a specific period for such Approval) will be deemed to constitute
Approval, then the failure of the Reviewing Party to so respond in writing
(including stating with particularity the basis for any denial or withholding of
such Approval) to any Matter within thirty (30) days of receipt of the written
request of the other party (or within such other period of time for response if
the Lease otherwise expressly provides a specific period for such Approval),
shall be deemed to constitute the Approval by such Reviewing Party as to the
Matter.

          38.  Right of First Offer.
               --------------------

               38.1  Grant of Right.  Subject to the provisions of Section
                     --------------
38.7 hereof, Landlord shall not, at any time during the term of this Lease,
offer to sell or accept an offer to purchase (collectively herein called an
"offer to sell") the Property or any part thereof without first giving to Tenant
at least thirty (30) days prior written notice of Landlord's election to sell
the Property, which notice is hereinafter referred to as the "Notice of Sale".

                                       26
<PAGE>

               38.2      Notice of Sale. The Notice of Sale shall include the
                         --------------
price and other terms and conditions reasonably appropriate to a sales
transaction on which Landlord is willing to sell the Property.

               38.3      Response by Tenant. For a period of fifteen (15) days
                         ------------------
after receipt by Tenant of the Notice of Sale, and only during such period,
Tenant shall have the right to accept the offer of sale set forth in the Notice
of Sale only by doing all of the following prior to the expiration of said
fifteen (15) day period: (i) giving written notice of acceptance to Landlord,
which notice shall state that Tenant agrees to purchase the Property on the same
terms, price and conditions as set forth in the Notice of Sale and (ii)
delivering to Landlord at the same time the full amount of any reasonable
earnest money deposit specified in the Notice of Sale.

               38.4      No Response. In the event that Landlord does not
                         -----------
receive written notice of Tenant's acceptance of the offer to sell and the
earnest money deposit within said fifteen (15) day period, there shall be a
conclusive presumption that Tenant has elected not to exercise Tenant's right to
purchase the Property pursuant to this Section 38, and Landlord may sell the
Property to a third party within six (6) months thereafter so long as the
purchase price paid by the third party purchaser is not materially less (with
any purchase price less than 98.5% of the purchase price set forth in the
Notice of Sale deemed to be materially less) than the purchase price specified
in the Notice of Sale and the other terms and conditions of the sale to the
third party are the same as or more onerous to the purchaser than those
specified in the Notice of Sale.

               38.5      Termination. The foregoing right of first offer shall
                         -----------
terminate:

                         (a)  upon expiration or other termination of the term
of this Lease; or

                         (b)  subject to the provisions of Section 38.7 hereof,
in the event Tenant fails to exercise its rights under this Section 38 and a
sale to a person or entity consistent with the requirements of this Section 38
is thereafter consummated, then upon the date of the closing of such sale.

               38.6      Continuation of Rights. Unless terminated in accordance
                         ----------------------
with Section 38.5 above, Tenant's rights under this Section 38 shall continue in
full force and effect (as to all future contemplated sales of the Property or
any part thereof).

               38.7      Exempted Sales. Notwithstanding the provisions of
                         --------------
Section 38.1 above, in the event that Landlord offers to sell the Property or
any part thereof to a Permitted Affiliate (as defined below) or as part of a
package of three or more separate real properties (but only if the aggregate
fair market value of all real properties contained in such package equals or
exceeds an amount equal to twice the then fair market value of the Property)
also owned by Landlord, then such offer to sell shall not be subject to Tenant's
right of first offer as set forth

                                       27
<PAGE>

in Sections 38.1 through 38.4 of this Lease. Notwithstanding the provisions of
Section 38.5 above, any transfer of title to the Property or any part thereof
pursuant to the foregoing provisions of this Section 38.7 shall not cause
Tenant's right of first offer under this Section 38 to terminate, and the right
of first offer set forth in this Section 38 shall remain in full force and
effect with respect to the Property following any such transfer. As used above,
the term "Permitted Affiliate" means (i) any entity controlling, controlled by
or under common control with Landlord; (ii) any (a) officer or director of or
(b) member, partner, shareholder or other equity holder, in either such event
with an equity interest of ten percent (10%) or more in, any of the foregoing
entities or (ii) any combination of (i) and (ii).

          39.  Tenant's Consent to New Contract Affecting the Property. Landlord
               -------------------------------------------------------
shall not, after the date of execution of this Lease, enter into or provide
consent for any other party to enter into, without Tenant's written consent
which shall not be unreasonably withheld or delayed, any contract or agreement
pertaining to the Property which may be reasonably expected to adversely
interfere with any of Tenant's rights under this Lease. In the event that any
contract or agreement which interferes with any of Tenant's rights under this
lease is entered into by Landlord, then Tenant shall have the unilateral right
to terminate this Lease.

          40.  Landlord's Default.
               ------------------

               40.1      Events of Default. A "Landlord Event of Default" under
                        -----------------
this Lease shall exist if any of the following events shall occur:

                         (a)  Landlord shall have failed to pay any sum required
to be paid hereunder within fifteen (15) days after receipt of written notice
from Tenant that such amount is past due; or

                         (b)  If Landlord shall have failed to perform any term,
covenant or condition of this Lease, except those requiring the payment of
money, and Landlord shall have failed to cure such breach within thirty (30)
days after written notice from Tenant where such breach could reasonably be
cured within such thirty (30) day period; provided, however, that where such
failure could not reasonably be cured within such thirty (30) day period, that
Landlord shall not be in default if it has commenced such performance within the
thirty (30) day period and diligently thereafter prosecutes the same to
completion.

Tenant shall use commercially reasonable efforts to cause a copy of any notice
of default delivered to Landlord as provided above likewise to be delivered to
any Mortgagee, written notice of the name and address of which has then
previously been provided to Tenant by Landlord, at approximately the same time
that such notice of default is delivered to Landlord.

               40.2      Tenant's Remedies. Upon a Landlord Event of Default,
                         -----------------
Tenant shall have the following remedies, in addition to all other rights and
remedies provided by law (except to the extent waived by Tenant herein) or
otherwise provided in this Lease, to which Tenant may resort cumulatively or in
the alternative:

                                       28
<PAGE>

                         (a)  Tenant may offset amounts owed by Landlord against
Basic Rent and Additional Rent by giving Landlord written notice of such offset.

                         (b)  Tenant may take such acts as it deems reasonably
necessary to cure Landlord's default. It Tenant spends any funds in connection
with such cure, Landlord shall pay to Tenant within fifteen (15) days after
written request the amount of funds so spent by Tenant. Tenant shall be entitled
to interest on the funds expended by Tenant at the Interest Rate from the end of
Landlord's applicable cure period. If Landlord fails to make such payment within
such fifteen (15) day period, Tenant may offset such funds and all interest
accrued thereon from Basic Rent and Additional Rent by giving Landlord written
notice of such offset.

          41.  Parking. Tenant shall be provided on an exclusive basis and at
               -------
no additional cost with five hundred twenty-six (526) automobile parking spaces;

shown on the Site Plan attached hereto as Exhibit "B".

          42.  Signage. Landlord shall provide for prominent building exterior

          43.  Authority. The undersigned parties hereby warrant that they have
               ---------
proper authority and are empowered to execute this Lease on behalf of Landlord
and Tenant, respectively.

          44.  Title. This Lease is made subject to all matters of public record
               -----

Company, Order No. 9700394, a copy of which is attached hereto as Exhibit "D"
(including all interlineated changed marked thereon, the Title Report), as shown
on Schedule B-Section 1 thereof. Chicago Title Insurance Company (or another
title insurance company reasonably acceptable to Tenant) shall be irrevocably
committed to issue to Tenant a leasehold owner's ALTA Extended Coverage Policy
of Title Insurance, together with such endorsements as Tenant may reasonably
require, showing Tenant as the owner of the leasehold estate under this Lease,
subject only to such exceptions to title as Tenant may approve, at standard
premium rates, as a condition precedent to Tenant's obligations under this
Lease. Landlord shall use due diligence to enforce all rights and easements
which are appurtenant to the Property.

          45.  Non-Disturbance Agreement. If either at the time of execution of
               -------------------------
this Lease or the recording of a short form memorandum of this Lease pursuant to
Section 33 hereof, there is then a Mortgage existing as a lien against title to
the Property (hereinafter referred to as an "Existing Mortgage"), Landlord shall
cause the Mortgagee under the Existing Mortgage to execute and deliver to Tenant
within thirty (30) days after the date of execution of this Lease, a Non-
Disturbance Agreement in form and content reasonably acceptable to both Tenant
and the Mortgagee under the Existing Mortgage, pursuant to which the Mortgagee
shall agree that in the

                                       29
<PAGE>

event of foreclosure of the Existing Mortgage, such Mortgagee (or any purchaser
at any foreclosure sale) shall agree that so long as there is not then an
uncured Event of Default on the part of Tenant under this Lease, as the same may
be amended in the future, this Lease shall remain in full force and effect and
such beneficiary (or any purchaser at any foreclosure sale) shall recognize the
tenancy of Tenant on the terms and conditions contained in this Lease,
including, without limitation, Tenant's right of first offer in Section 38
hereof, and shall further expressly acknowledge that absent an Event of Default
by Tenant under this Lease or termination of this Lease, any insurance proceeds
associated, with any damage or destruction. of the Property shall be made
available for Restoration of the Property in accordance with the provisions of
Section 20 of this Lease ("Non-Disturbance Agreement"). The recordation of such
Non-Disturbance Agreement in the Office of the Recorder of Maricopa County,
Arizona, shall be a condition precedent to Tenant's obligations under this
Lease. In addition, this Lease, as it may be amended in the future, shall not be
subordinate to any future Mortgage unless the Mortgagee under such future
Mortgage shall execute a Non-Disturbance Agreement.

          46.  Holding Over. Tenant shall have the right to remain on the
               ------------
Property for up to three (3) months after expiration of the Lease Term on the
same terms and conditions, including Basic Rent, as applicable upon the
expiration. Tenant may terminate this holdover earlier than the expiration of
such three (3) month period by providing at least sixty (60) days prior notice.
At any time from and after the date that is three (3) months prior to the
expiration of the Lease Term, Landlord may deliver written notice to Tenant
asking whether Tenant will avail itself of its right to hold over as set forth
above. Within twenty (20) days following Tenant's receipt of such written
