                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Consolidated Financial Statements

The accompanying consolidated financial statements have been prepared by WAM!NET
Inc. ("We," "us," "our") without audit and reflect all adjustments (consisting
only of normal and recurring adjustments and accruals) which are, in the opinion
of management, necessary to present a fair statement of the results for the
interim periods presented. The statements have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Article 10 of regulation S-X, but omit
certain information and footnote disclosures necessary to present the statements
in accordance with generally accepted accounting principles. The results of
operations for the interim periods presented are not necessarily indicative of
the results to be expected for the full fiscal year. These financial statements
should be read in conjunction with our audited Consolidated Financial Statements
for the year ended December 31, 1998. The December 31, 1998 balance sheet was
derived from audited financial statements, but does not include all disclosures
required by generally accepted accounting principles. Certain amounts for the
prior year have been reclassified to conform to current year presentation.


2.   Consolidation

The consolidated financial statements include our accounts and our wholly-owned
subsidiaries: FreeMail, Inc., NetCo Communications of Canada, Inc., WAM!NET
Japan KK and WAM!NET U.K. Limited (formerly 4-Sight Limited). All intercompany
transactions have been eliminated.


3.   Preferred Stock

In January 1999, we issued the 1999 MCI WorldCom Convertible Note and in January
1999 and March 1999, we borrowed $10.0 million and $15.0 million, respectively.
The 1999 MCI WorldCom Convertible Note was converted into 2,196,317 shares of
our Class D Convertible Preferred Stock, par value $.01 per share (the "Class D
Preferred Stock"), immediately prior to the closing of the Silicon Graphics,
Inc. investment discussed below ("SGI Investment"). In connection with the MCI
WorldCom Convertible Note, we issued warrants to MCI WorldCom to purchase a
total of 350,000 shares of Common Stock. The warrants have an exercise price of
$.01 and are exercisable from April 30, 1999 until April 30, 2004.

In March 1999, we entered into the SGI Investment, providing for the purchase by
SGI of 5,710,425 shares of our Class B Convertible Preferred Stock, par value
$.01 per share (the "Class B Preferred Stock"), and 878,527 shares of our Class
C Convertible Preferred Stock, par value $.01 per share (the "Class C Preferred
Stock"). The holders of a majority of the Class B Preferred Stock have the right
to designate one member of our Board of Directors. The aggregate consideration
received by us for the Class B Preferred Stock and the Class C Preferred Stock
was $75 million, of which $35 million was paid in cash and $40 million was paid
by transfer to us of a corporate campus facility. The Class B Preferred Stock
and the Class C Preferred Stock will be convertible on a one-to-one basis into
Common Stock (subject to anti-dilution adjustments) and will have the right to
vote with the Common Stock, on an as-converted basis, as a single class. The
Class B Preferred Stock and Class C Preferred Stock are convertible immediately
following the issuance date and 18 months following the issuance date,
respectively. The shares of convertible Common Stock into which the Class B
Preferred Stock and the Class C Preferred Stock are subject to certain
registration rights.

Sale Leaseback

On September 30, 1999, we entered into a Purchase and Sale Agreement and Escrow
Instructions together with a Net Lease Agreement or Memorandum of Lease
(collectively, "The Sale/Lease Back Agreement") with CCPRE-Eagan, LLC, ("CCPRE")
a Delaware Limited Liability Company, and an affiliate of Chase Bank, New York.
Pursuant to the Sale/Lease Back Agreement, we conveyed our corporate
headquarters facility, including land, building and personal property to CCPRE
for a total purchase price of $38 million. Under the Sale/Lease Back Agreement,
we agreed to lease the facility from CCPRE for a term of 20 years with three
five-year options at a minimum monthly rent increasing from $481,000 per month
during the first year of the initial term to $959,000 per month during the last
year of the initial term. We also agreed to pay all taxes, assessments,
utilities and other governmental charges. Under the Sale/Lease Back Agreement,
we may repurchase the corporate headquarters facility on the 24th or 36th month
anniversary of the agreement. The Sale/Lease Back Agreement entitles CCPRE to
require us to repurchase our corporate headquarters facility at any time
following the 36th month anniversary of the Agreement for the sum $41.8 million,
less the amount of certain payments made under the lease. As additional
consideration for the Sale/Lease Back Agreement, we issued Chase Capital
Partners ten-year warrants to purchase 325,000 shares of common stock at an
initial exercise price of $12.00 per share. The initial exercise price is
subject to antidilution adjustments. The warrant agreement entitles the holder
to require us to repurchase shares issued upon exercise of the warrant if we
elect to repurchase our corporate headquarters facility prior to an initial
public offering of our common stock, at a per share purchase price equal to 92%
of fair market value determined by appraisal. In connection with the warrant
agreement, Chase Capital Partners entered into agreements with MCI WorldCom and
SGI entitling the holder of the warrants to include a portion of the warrants,
or shares issuable upon exercise, in any transaction occurring prior to our
initial public offering in which either MCI WorldCom or SGI sold 10% or more of
its ownership of our securities.

Item 2--Management's Discussion and Analysis of Financial Condition and Results
        of Operations


           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


         The following discussion and analysis is based on the historical
results of WAM!NET Inc. ("We," "us" "our") and should be read in conjunction
with our Financial Statements included herein. The following discussion contains
forward-looking statements that reflect our plans, estimates and beliefs. Our
actual results could differ materially from those discussed in the
forward-looking statements.

Overview

         We offer a suite of electronic data delivery services including our
Direct Service, On-Ramp Service and Internet Gateway Services. Our initial focus
through 1998 was our Direct Service. This is our fastest, most secure and most
reliable transport service, that includes installation of equipment on our
customer's premises and provision of telephone service connecting the equipment
to our network. This service provides direct, guaranteed and managed access and
transport over our private network. Customers choose from a variety of
capacities, speeds and throughput levels to meet their requirements. We released
our On-Ramp Service in Europe during the first quarter of 1999 and in North
America during the second quarter of 1999. Our On-Ramp service allows customers
to connect to our network using software we provide, an ISDN card, which we also
offer, and a dial-up ISDN or similar telephone service which our customer
obtains. We introduced our Internet Gateway Service to our Direct Service
customers in the third quarter of 1999. Internet Gateway service allows
connection to our network over the Internet. Both On-Ramp and Internet Gateway
services are targeted to facilitate growth in the number and size of workflow
groups by permitting connectivity at lower costs commensurate with lower
capacity needs for smaller users who are often key participants in workflow. At
September 30, 1999, we had over 5,000 subscribers using our data delivery
services.

                                      -9-

         Revenues.

         Service revenue. Our service revenue is directly related to customer
traffic through our global private network which is related to the number of,
and degree of utilization by, workflow groups who connect among themselves
through our network. Our service revenue is derived primarily from annual or
multi-year service contracts, many of which have automatic renewal or extension
provisions. These contracts generally include a minimum monthly fee and
additional charges for usage that exceeds an included monthly minimum. We
currently offer our services at scaled minimum usage fees, which typically range
for Direct Service from $650 per month to $4,000 per month, and for On-Ramp
Service from $45 per month to $360 per month. Our Internet Gateway is priced
primarily on a per-megabyte basis. We begin to earn service revenue from Direct
Service customers following installation of equipment and service at a
customer's premises, which typically lags contract signing by 60 to 90 days. We
begin to earn service revenue from our other services upon contract signing
and/or usage. We began to record revenue from our On-Ramp Service in March 1999,
and began to record revenue from Internet Gateway Service in September of 1999.
We expect to introduce our initial WAM!BASE(R) data storage services during the
first quarter of 2000.

         Software and hardware sales. Revenue from software and hardware sales
resulted primarily from the sale of 4-Sight ISDN Manager(TM) software and ISDN
cards. In addition, our On-Ramp Service customers may choose to make a single
upfront payment and purchase software instead of paying monthly service fees
under contracts for the use of our On-Ramp software. In both cases these
purchases appear as software and hardware sales in our revenue. We expect
revenue from software and hardware sales to decline upon completion of the
long-term contracts for 4-Sight ISDN Manager(TM) and ISDN cards.

         No single customer accounted for more than 5% of our revenues for the
nine month period ended September 30, 1999 on a consolidated basis.

         Operating Expenses.

         Network communications. Network communications expense represents the
largest direct cost associated with providing our Direct Service. Network
communications expense includes both the costs of the high bandwidth, backbone
carrier services interconnecting our global infrastructure of network operation
and data storage centers and distribution hubs as well as the costs of local
loop telephone circuits connecting our network access devices from a customer's
premises to the nearest distribution hub. Local telephone circuit connections
provided by local exchange carriers account for the substantial majority of
these charges, with significant differences between urban and rural connection
costs. National and international carrier service, accounts for the balance of
these charges. Network communication expense is generally a fixed monthly cost
per circuit. We expect that network communications expense will increase as our
network expands; however, we expect that the cost of these expenses as a
percentage of revenue will decline with increasing utilization of our network.
We also believe that growing competition among telephony and communications
providers may reduce the cost of local telephone circuit and backbone
connections. We actively seek to obtain and deploy technologies that will reduce
the costs of local telephone circuit connections, such as wireless technologies,
remote dial-up capabilities and DSL. We also intend to use our network
management tools to optimize the use of existing and planned network capacity as
volume increases and traffic patterns begin to emerge. We continue to incur
substantial network communication expense as we deploy our network and related
services and applications globally; however, we expect the network
communications expense as a percentage of revenue to decline.

         Software and hardware. Software and hardware expense reflects the costs
of software and hardware sold.

         Network operations and development. Network operations and development
expense represents costs directly associated with developing, maintaining,
managing and servicing our global private network and expanding our service
offerings. These costs include direct labor, vendor service fees,
point-of-presence charges and research and development charges, which are often
incurred in advance of receiving revenue. Our currently installed

                                      -10-
<PAGE>

network operation centers account for the substantial majority of these direct
labor and operating costs. Most of the costs associated with the development of
new services and applications, such as WAM!BASE(R), WAM!PROOF(R), On-Ramp and
Internet Gateway, are accounted for as network operations expenses and are
incurred in advance of receiving revenue. We expect that network operations
costs will increase as our network expands; however, the cost of network
operations as a percentage of revenue is expected to decline.

         Selling, general and administrative. Our selling expense consists
primarily of the salaries and commissions of our direct sales force and our
global marketing groups, commissions for channel partners, and the costs of
ongoing marketing activities such as promotions and channel development. Our
sales and marketing efforts through the end of 1998 were primarily intended to
create awareness of our services, stimulate trial use and induce integration
into customer workflow. With the growth of our installed customer base, we began
in 1999 integrating our services into our customers' workflow and expanding the
size and number of workflow groups with our more affordable On-Ramp and Internet
Gateway connectivity options. We expect to continue to incur significant sales
and marketing expenses in order to obtain increased penetration in our markets
and to generate increased traffic among existing customers.

         Our general and administrative expense includes administrative
salaries, related overhead and professional service fees. These costs reflect
expenditures related to the rapid growth and expansion of our administrative
infrastructure necessary to manage our globally expanding operations, and
professional service fees for financing activities, contract negotiations and
acquisitions. We continue to incur general and administrative expenses as we
continue to deploy our network and related services and applications globally;
however, we expect the cost of general and administrative expenses as a
percentage of revenue to decline.

         Depreciation and amortization. We retain ownership of the customer
premise equipment and most of the hardware and software necessary for our
customers to use our services on a turn-key basis. Depreciation and amortization
expense includes depreciation of this hardware and software as well as the
equipment located in our distribution hubs and network operation and data
storage centers. We also amortize certain costs relating to the acquisitions of
4-Sight and Freemail, which we acquired using the purchase method of accounting.
We anticipate additional capital investments in our network infrastructure
commensurate with customer demand and market opportunity. As a result, we
anticipate that depreciation and amortization expense will continue to increase
in future periods as we continue to purchase equipment and expand operations;
however, we expect depreciation and amortization expense as a percentage of
revenue to decline.

Results of Operations

Three and Nine Month Periods Ended September 30, 1999 Compared with Three and
Nine Month Period Ended September 30, 1998

         Revenues.

         Net Service revenue. Net Service revenue for the three month period
ended September 30, 1999 was $4.8 million, compared to $1.8 million for the
three month period ended September 30, 1998, an increase of $3.0 million, or
166.7%. Net Service revenue for the nine month period ended September 30, 1999
was $11.9 million, compared to $4.3 million for the nine month period ended
September 30, 1998, an increase of $7.6 million, or 176.7%. This increase in
revenue during each current period was primarily due to growth in the number of
customers purchasing Direct Services and On-Ramp Services, increased utilization
by customers, and price increases in monthly fees.

         Software and hardware sales. Revenues from software and hardware sales
for the three month period ended September 30, 1999 were $2.0 million, compared
to $3.7 million for the three month period ended September 30, 1998 a decrease
of $1.7 million or 45.9%. Revenues from software and hardware sales for the nine
month period ended September 30, 1999 were $5.6 million, compared to $8.5
million for the nine month period ended September 30, 1998, a decrease of $2.9
million, or 34.1%. The decrease in each current period is due to our

                                      -11-
<PAGE>

migration from sales of 4-Sight software and hardware as stand-alone products to
sales of service contracts, partially offset by software purchases associated
with On-Ramp Service agreements.

         Total Revenue. Total revenue for the three month period ended September
30, 1999 was $6.8 million, compared to $5.5 million for the three month period
ended September 30, 1998, an increase of $1.3 million, or 23.6%. Total revenue
for the nine month period ended September 30, 1999 was $17.5 million, compared
to $12.8 million for the nine month period ended September 30, 1998, an increase
of $4.7 million, or 36.7%. Increased service revenue during each period was
partially offset by decreases in hardware and software sales, as described
above.

         Operating Expenses.

         Network communications. Network communications expense for the three
month period ended September 30, 1999 was $6.8 million, compared to $4.6 million
for the three month period ended September 30, 1998, an increase of $2.2
million, or 47.8%. Network communications expenses for the nine month period
ended September 30, 1999 were $19.5 million, compared to $11.5 million for the
nine month period ended September 30, 1998, an increase of $8.0 million, or
69.6%. The increase in each current period resulted from increased costs for
local loop connections related to growth in the number of our Direct Service
customers, and from expenses on network coverage through installation of
additional hubs for domestic and foreign network operations. The average monthly
communications expense per Direct Service customer installation decreased
overall 13.5% during each of the current periods. This trend reflects more
efficient use of our backbone as we add more Direct Service customers to our
network, a beneficial shift in the geographic mix of our customers, and
generally declining costs of backbone capacity and North American local loop
connections. These trends were partially offset by growth in our Direct Service
customer base in Europe, where local loop costs are generally higher than in
North America.

         Software and hardware. The cost of software and hardware for the three
month period ended September 30, 1999 was $0.8 million, compared to $1.2 million
for the three month period ended September 30, 1998, a decrease of $0.4 million,
or 33.3%. The cost of software and hardware for the nine month period ended
September 30, 1999, was $2.2 million, compared to $2.6 million for the nine
month period ended September 30, 1998, a decrease of $0.4 million, or 15.4%.
This decrease reflects the decline in software and hardware sales as described
above.

         Network operations and development. Network operations and development
expense for the three month period ended September 30, 1999 was $6.4 million,
compared to $11.6 million for the three month period ended September 30, 1998, a
decrease of $5.2 million, or 44.8%. Network operations and development expense
for the nine month period ended September 30, 1999 was $17.2 million, compared
to $24.0 million for the nine month period ended September 30, 1998, a decrease
of $6.8 million, or 28.3%. The decrease in each current period was primarily due
to completion of On-Ramp development and the termination of associated
development costs, partially offset by costs incurred for establishing our
network operations center in Belgium and deploying our network in Europe. This
category of expense also includes one-time costs related to the acquisition of
4-Sight in March 1998, and costs for development of On-Ramp, Internet Gateway
and WAM!BASE which were incurred during 1998 and 1999. We anticipate a lower
level of development costs for continuing Internet Gateway and WAM!BASE
development in future periods.

         Selling, general and administrative. Selling, general and
administrative expense for the three month period ended September 30, 1999 was
$9.6 million, compared to $10.0 million for the three month period ended
September 30, 1998, a decrease of $0.4 million, or 4.0%. Selling, general and
administrative expense for the nine month period ended September 30, 1999 was
$31.0 million, compared to $33.1 million for the nine month period ended
September 30, 1998, a decrease of $2.1 million, or 6.3%. This decrease is due to
a one-time $11.5 million non-cash compensation charge relating to the vesting of
option contracts held by certain of our officers that occurred in the period
ended September 30, 1998, partially offset by costs incurred following the
acquisition of 4-Sight in March, 1998 and by increases in other selling, general
and administrative expenses associated with expanded operations during the
current nine month period. After adjusting for the one-time charge during 1998,

                                      -12-
<PAGE>

recurring selling, general and administrative expense during the nine month
period ended September 30, 1999 increased $9.4 million, or 43.5% over the
comparable adjusted amount for the nine month period ended September 30, 1998.
The increase was primarily due to (i) expansion of our European sales force,
partially offset by reductions and realignments in our North American sales
force, (ii) increased marketing expense for trade show attendance associated
with new service promotions and (iii) increased costs associated with the
restructuring of our executive and administrative management team to support our
new sales and marketing focus. Management expects selling, general and
administrative expense will continue to decline as a percentage of revenue.

         Depreciation and amortization. Depreciation and amortization for the
three month period ended September 30, 1999 was $8.9 million, compared to $5.3
million for the three month period ended September 30, 1998, an increase of $3.6
million, or 67.9%. Depreciation and amortization for the nine month period ended
September 30, 1999 was $24.9 million, compared to $11.4 million for the nine
month period ended September 30, 1998, an increase of $13.5 million, or 118.4%.
This increase in each current period is primarily due to depreciation of
additional network and related equipment purchased for network expansion during
1998 and 1999.

         Interest income. Interest income for the three month period ended
September 30, 1999 was $0.1 million, compared to $0.5 million for the three
month period ended September 30, 1998, a decrease of $0.4 million, or 80.0%.
Interest income for the nine month period ended September 30, 1999 was $0.5
million, compared to $1.6 million for the nine month period ended September 30,
1998, a decrease of $1.1 million, or 68.8%. The decrease in interest income in
each current period was primarily due to the decrease in our average monthly
balance of cash and cash equivalents during the period.

         Interest expense. Interest expense for the three month period ended
September 30, 1999 was $8.0 million, compared to $6.3 million for the three
month period ended September 30, 1998, an increase of $1.7 million, or 27.0%.
Interest expense for the nine month period ended September 30, 1999 was $25.5
million, compared to $15.8 million for the nine month period ended September 30,
1998, an increase of $9.7 million, or 61.4%. The increase was primarily due to
(i) the increase in long-term unsecured debt we incurred during 1998 to fund our
operations and to acquire 4-Sight, consisting primarily of our 13.25% senior
discounted notes due 2005 (the "1998 Notes") in the accreted principal amount of
$153.0 million at September 30, 1999, and (ii) the increase in equipment
financing. In the nine month period ended September 30, 1999 we also incurred
interest expense (i) in the amount of $2.8 million in connection with the 13.25%
subordinated unsecured convertible note, which converted into equity in March
1999, and (ii) in the amount of $6.5 million representing financing costs
including the current portion of the attributed cost incurred for the issuance
of warrants in connection with certain financing transactions, including our
13.25% senior discount notes.

         Other income. Other income for the three month period ended September
30, 1999 was $0.5 million, compared to $0.7 million for the three month period
ended September 30, 1998, a decrease of $0.2 million, or 28.6%. %. Other income
for the nine month period ended September 30, 1999 was $0.8 million, compared to
$0.8 million for the nine month period ended September 30, 1998. The 1999 other
income primarily reflects receipt of rental income received from SGI in
connection with our lease to SGI in June, 1999 of a portion of the corporate
campus facility in Eagan which we purchased from SGI in March, 1999. This income
was partially offset by our continuing rental obligations for vacated
facilities.

         Net loss. Our net loss of $33.0 million for the three month period
ended September 30, 1999 increased $0.7 million, or 2.2%, compared to a net loss
of $32.3 million for the three month period ended September 30, 1998. Our net
loss of $101.5 million for the nine month period ended September 30, 1999,
increased $18.3 million, or 22.0%, compared to a net loss of approximately $83.2
million for the nine month period ended September 30, 1998. This increase is
related to expenses associated with the continuing operation, deployment and
marketing of our network and network services, for the expansion of European
operations, for increased depreciation and amortization over a larger equipment
base and for increased interest expense.

                                      -13-

Liquidity and Capital Resources

         Since inception, we have incurred net losses and experienced negative
cash flow. We expect to continue to operate at a net loss and experience
negative cash flow for the foreseeable future. Our ability to achieve
profitability and positive cash flow from operations will depend on our ability
to grow our revenue substantially and achieve other operating efficiencies.

         For the nine month period ended September 30, 1999, we used $54.4
million of net cash in operating activities primarily for operating expenses,
including network communications, salaries, travel, consulting and legal
expense. During that period we used $22.6 million of net cash in investing
activities primarily for the expansion of our network and storage
infrastructure. Since January 1, 1999, we have obtained $103.3 million of net
cash proceeds from financing activities, consisting of $36.8 million from the
sale leaseback of our building and land, $59.5 million from the issuance of
short-term debt and preferred stock to MCI WorldCom and SGI, and $7.0 million
from other net borrowings under credit facilities and equipment financing
arrangements. The increase of $39.0 million in our building and land assets
during the period result from our acquisition of the SGI corporate campus
facility in March 1999 in exchange for the issuance of our preferred stock.
Changes in other asset and liability balances during the recent nine month
period related to timing of expense recognition.

         On January 13, 1999, we issued the 1999 MCI WorldCom convertible note
in the principal amount of $25.0 million due August 28, 1999. Under the 1999 MCI
WorldCom convertible note we borrowed $10.0 million on January 13, 1999 and
$15.0 million on March 4, 1999. Also, on that date, we consummated the SGI
investment pursuant to which SGI purchased 5,710,425 shares of Class B
convertible preferred stock and 878,527 shares of our Class C convertible
preferred stock for aggregate net cash proceeds of $35.0 million and $40.0
million by way of transfer to us of SGI's corporate campus facility in Eagan,
Minnesota. Immediately prior to the closing of our transaction with SGI, the
1999 MCI WorldCom convertible note was converted into 2,196,317 shares of Class
D convertible preferred stock. In connection with the issuance of the 1999 MCI
WorldCom convertible note, we also issued warrants to MCI WorldCom to purchase
150,000 and 200,000 shares of common stock at an exercise price of $.01 per
share after April 30, 1999 and exercisable until April 30, 2004.

         Effective June 1, 1999 we amended our 1997 agreement for the
acquisition of Freemail to change the amount and rate of payment of contingent
consideration due to the former Freemail shareholders. We have decreased the
amount payable from $3.0 million cash to $2.0 million, payable $1.0 million in
cash and $1.0 million in shares of our common stock at fair market value. The
rate of payment has also been changed from 5% of revenue from a selected class
of customers to 5% of our total collected revenue, calculated quarterly. In
accordance with this amendment, the first payment was made by October 30, 1999,
for the quarter ended September 30, 1999.

         On July 16, 1999, we entered into a $20.0 million, two year credit
facility with Foothill Capital Corporation. The credit facility contains a $10.0
million term loan which was repaid from the proceeds of the sale/License
Agreement with CCPRE Eagan, LLC. The remainder of the facility is a revolving
credit facility under which Foothill will lend us up to an additional $10.0
million based upon a borrowing base consisting of our recurring billings and
collections from its U.S. customers. Amounts outstanding under the credit
facility incur interest at the Wells Fargo Bank reference rate plus 1.75%
(currently 9.75% per year). The credit facility is secured by a lien on certain
unencumbered and lienable assets. The credit facility requires us to obtain
certain minimum gross margins, specified levels of network access device
installations and minimum EBITDA for the quarter ending September 30, 1999, and
for each quarter thereafter until maturity. It also provides for annual limits
on the amount of our capital expenditures. Foothill has agreed under certain
circumstances to subordinate or release its lien on equipment to permit us to
obtain equipment financing from third parties. The credit facility is
automatically renewable at maturity until cancelled in accordance with its
terms. We have currently borrowed approximately $4.0 million under the credit
facility.

On September 30, 1999, we entered into a Purchase and Sale Agreement and Escrow
Instructions together with a Net Lease Agreement or Memorandum of Lease
(collectively, "The Sale/Lease Back Agreement") with CCPRE-Eagan,

                                      -14-
<PAGE>

LLC, ("CCPRE") a Delaware Limited Liability Company, and an affiliate of Chase
Bank, New York. Pursuant to the Sale/Lease Back Agreement, we conveyed our
corporate headquarters facility, including land, building and personal property
to CCPRE for a total purchase price of $38 million. Under the Sale/Lease Back
Agreement, we agreed to lease the facility from CCPRE for a term of 20 years
with three five-year options at a minimum monthly rent increasing from $481,000
per month during the first year of the term to $959,000 per month during the
last year of the initial term. We also agreed to pay all taxes, assessments,
utilities and other governmental charges. Under the Sale/Lease Back Agreement,
we may repurchase the corporate headquarters facility on the 24th or 36th month
anniversary of the agreement. The Sale/Lease Back Agreement entitles CCPRE to
require us to repurchase our corporate headquarters facility at any time
following the 36th month anniversary of the Agreement for the sum $41.8 million,
less the amount of certain payments made under the lease. As additional
consideration for the Sale/Lease Back Agreement, we issued Chase Capital
Partners ten-year warrants to purchase 325,000 shares of common stock at an
initial exercise price of $12.00 per share. The initial exercise price is
subject to antidilution adjustments. The warrant agreement entitles the holder
to require us to repurchase shares issued upon exercise of the warrant if we
elect to repurchase our corporate headquarters facility prior to an initial
public offering of our common stock, at a per share purchase price equal to 92%
of fair market value determined by appraisal. In connection with the warrant
agreement, Chase Capital Partners entered into agreements with MCI WorldCom and
SGI entitling the holder of the warrants to include a portion of the warrants,
or shares issuable upon exercise, in any transaction occurring prior to our
initial public offering in which either MCI WorldCom or SGI sold 10% or more of
its ownership of our securities.

         Our ability to continue to fund our operating losses as we expand our
business depends on our ability to obtain additional sources of financing. We
expect that our available operating capital as of October 31, 1999, as evidenced
by cash, cash equivalent investments, and availability under existing credit
facilities, together with borrowings under facilities from financial
institutions with whom we are currently negotiating, will be sufficient to fund
our operating losses, capital expenditures, lease payments and working capital
requirements for the remainder of our current fiscal year. We are seeking
additional financing through long- and short-term financing from banks,
financial institutions, and vendors and the issuance of our equity securities.
If additional sources of funding cannot be obtained during the course of our
fiscal year ending December 31, 1999, due to a constraint of available operating
capital, we will be required to significantly slow our global market
penetration, network growth and product development. In addition, should we be
unable to generate cash from operating or investing activities to fund our
operations and network growth during 1999, management expects that it would
implement plans to reduce cash expenditures. The reduction of cash expenditures
would have a material adverse effect on our global revenue and network expansion
plans. We believe that the most evident and clearly measurable impact resulting
from these reductions would be a significant decrease of installed network
customers for the year ending December 31, 1999. A material reduction in the
base of installed customers would slow the growth of our recurring revenue
stream, which is dependent upon customer utilization of our excess network
capacity. Reductions in network utilization would directly impact our network
revenue and could ultimately defer overall profitability of our service and
products. Another possible impact of the above outlined expenditure reductions
would be potentially material delays in software product development, the impact
of which could further erode customer retention and network utilization.



Year 2000 Compliance

         The Year 2000 issue is the result of computer-controlled systems using
two digits rather than four to define the applicable year. For example, computer
programs that have time-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. As for many other companies, this year
2000 computer issue poses a potential risk for us as a user of information
systems in the operation of our business, as a provider of managed, high-speed,
digital data delivery network service and the related computer technology and
software to customers, and as a customer of other organizations whose operations
may be affected by year 2000 compliance issues.

         Our State of Readiness. We have completed an assessment of our core
business information systems, many of which are provided by outside suppliers,
for year 2000 readiness and are extending that review to include a variety

                                      -15-
<PAGE>

of other information systems and related business processes used in our
operations. We have implemented necessary changes to critical systems, and
successfully tested them. We are also assessing the possible effect on our
operations of the year 2000 readiness of critical suppliers of products and
services. These include not just suppliers of components but also our
outsourcing partners in manufacturing as well as suppliers of basic utilities.
Our reliance on key suppliers, and therefore on the proper functioning of their
information systems and software, is increasing, and there can be no assurance
that another company's failure to address year 2000 issues could not have a
material adverse effect on our business, financial condition and results of
operation. Although our assessment is ongoing, we currently believe that
resolving these matters will not have a material adverse effect on our business,
financial condition and results of operations.

         Costs. We have not incurred material historical costs for year 2000
awareness, inventory assessment, analysis, conversion, testing or contingency
planning. We believe that we are unlikely to experience a material adverse
impact on our business, financial condition or results of operations due to year
2000 compliance issues.

         Potential Risks. We could face substantial claims by customers or loss
of revenue due to service interruptions, inability to fulfill contractual
obligations or to bill customers accurately and on a timely basis, and increased
expenses associated with litigation, stabilization of operations following
critical system failures and the execution of contingency plans. We could also
experience an inability by customers and others to pay, on a timely basis or at
all, obligations owed to us. Under these circumstances, the adverse effects
would be material, although not quantifiable at this time. Further, the
cumulative effect of these failures could have a substantial adverse effect on
the economy, domestically and internationally. The adverse effects of a domestic
or global recession or depression also could be material, although not
quantifiable at this time. We will continue to monitor business conditions to
assess and quantify material adverse effects, if any, that may result from the
year 2000 problem.

Item 3--Quantitative and Qualitative Disclosures About Market Risk

         Foreign Currency Exchange Rates. For the nine month period ending
September 30 ,1999, our revenues originating outside the U.S. were 36% of total
revenues. Currently, we do not employ currency hedging strategies to reduce the
risks associated with the fluctuation of foreign currency exchange rates. All of
our contracts are denominated in U.S. dollars except for those contracts entered
into by our foreign subsidiaries which are denominated in local currency. We are
unable to determine what effect, if any, the adoption and use of the Euro will
have in the future on our business, operating results, liquidity and financial
condition.

         Our international business is subject to risks typical of an
international business, including, but not limited to: differing economic
conditions, changes in political climate, differing tax structures, other
regulations and restrictions, and foreign exchange rate volatility. Accordingly,
our future results could be materially adversely impacted by changes in these or
other factors.

         Interest Rates. We invest cash in a variety of financial instruments,
including bank time deposits and fixed rate obligations of governmental entities
and agencies. These investments are denominated in U.S. dollars. Cash balances
in foreign currencies overseas are operating balances and are invested in
short-term time deposits of the local operating bank.

         Investments in fixed rate interest earning instruments carry a degree
of interest rate risk. Fixed rate securities may have their fair market value
adversely impacted due to a rise in interest rates. Due in part to these
factors, our future investment income may fall short of expectations due to
changes in interest rates, or we may suffer losses in principal if forced to
sell securities which have seen a decline in market value due to changes in
interest rates. Our investment securities are held for purposes other than
trading.

         We are exposed to market risk from changes in the interest rates on
certain of our outstanding debt. The outstanding loan balance under the
revolving credit facility bears interest at a variable rate based on prevailing
short-term interest rates in the U.S. and Europe. Based on the average
outstanding bank debt for the year ended December 31, 1998, a 100 basis point
change in interest rates would not change interest expense by a material amount.
For fixed rate debt such as our 13.25% senior discount notes, interest rate
changes affect its fair market value, but do not impact earnings or cash flows.

with the transaction contemplated by this Agreement, Purchaser may elect to
terminate this Agreement by delivering written notice thereof to Seller no later

except as otherwise provided in this Article 4, the parties shall have no
                                     ---------
further liabilities, rights or obligations under this Agreement, except as
expressly provided in this Agreement, and the Initial Deposit and the Additional
Deposit, together with interest thereon, shall be returned to Purchaser within
three (3) business days after Seller's receipt of Purchaser's termination
notice.

          (b) Seller agrees to make available to Purchaser and Purchaser's

the operation of the Property, including, but not limited to, all Books and
Records, Contracts, Development Agreements, the SGI Lease and the Permits.

communicate directly with, any consultant or other persons engaged by Seller in
connection with the operation of the Property.

and complete copies of all surveys, plans, reports, assessments, investigations,
inspections, tests, examinations and other due diligence materials obtained or
prepared by, for or on behalf of Purchaser in connection with any part of the
Property or this transaction ("Purchaser's Reports").

notification thereof or by the Closing Date (whichever is sooner), of any new
violations (the "New Violations").  The failure of Purchaser to so notify Seller

exceed $25,000.00 (not including any sums required to remove any voluntarily
granted liens securing the payment of money), Seller shall have the right to

the Property subject to all Violations and New

Property, may deposit with the Title Company such amount of money, or deliver to
the Title Company such instruments of indemnification, as may be sufficient to
induce it to insure against collection of such liens or encumbrances, including
interest and penalties, out of the Real Property, in which event such liens and
encumbrances shall not constitute objections to title.

              ---------------------
payable in the year 1999, special or general assessments, sales taxes, occupancy
and entertainment taxes, water and sewer rents, rates and charges and vault

the amount of any such item is unascertainable on the Closing Date, the credit
therefor shall be based on the most recent available bill. If the actual amount
of any such item, when later determined and prorated for the applicable period,
differs from the credit given therefor at the Closing, the parties shall
promptly make the appropriate adjustment, and the party owing sums by reason of
such adjustment shall promptly remit such sums to the other party. Purchaser
shall give Seller written notice of the actual amounts of any such bills within
five (5) business days after Purchaser's receipt thereof.

          (c) Utility Contracts.  Telephone contracts and contracts for the
              -----------------
supply of heat, steam, cable, satellite, electric power, gas, lighting and any
other utility service, with Seller receiving a credit for all deposits, if any,
made by Seller as security under any such public service contract(s) if the same
is transferable and provided such deposit remains on deposit for the benefit of
Purchaser.

          (d) License Fees.  Fees paid or payable for Permits (other than
              ------------
Excluded Permits, unless and to the extent Purchaser has the benefit of such
Excluded Permits after the Closing Date).

          (e) Intentionally omitted.

          (f) Rents.  Rents, including without limitation all payments from
              -----
Tenant under the SGI Lease for items such as minimum or base rent, additional
rent, reimbursement for real estate taxes, for utilities, for operating and
maintenance expenses and for insurance, as well as other reimbursements (herein
collectively called "Rental Payments") received by Seller before or after the
Closing Date, shall not be prorated as of the Closing Date; Seller shall remain
entitled to retain and receive for its own account all Rental Payments
applicable prior to and during the term of the Master Lease.

          (g) Intentionally omitted.

          (h) Intentionally omitted.

          (i) Contracts.  On or before 5:00 p.m. Eastern Daylight Time on the
              ---------
Due Diligence Approval Date, Purchaser shall notify Seller in writing if
Purchaser elects not to assume at Closing any of the Contracts.  Provided that
this Agreement is not terminated prior to Closing pursuant to the terms hereof,
Seller shall give notice of termination of such disapproved Contracts to the
other parties thereto and Seller shall be responsible for all termination fees
payable as a result of the termination of such contracts.  However, Purchaser
agrees that as of the Closing Date, at Seller's option , Seller's property
manager and leasing agent, if any (whether such persons are independent
contractors or employees of Seller) shall continue to manage the affairs of the
Property.

          (j) Intentionally omitted.

          (k) No Adjustments.  This Section 9.1(k) shall govern any inconsistent
              --------------
provision herein.  Seller and Purchaser acknowledge that because Seller and
Purchaser will enter into the Master Lease on the Closing Date, it will be
unnecessary to prorate real estate taxes, assessments,

                                      21.
<PAGE>

utility charges, insurance premiums or any other operating expenses or
additional rent items that are to be paid directly by Seller as tenant under the
Master Lease. Accordingly, any and all of the costs, expenses, fees or other
charges set forth above in this Section 9.1 shall not be prorated as of the
Closing Date if and to the extent the same are operating expenses or other
additional rent items to be paid directly by Seller as tenant under the Master
Lease.

9.2  Closing Statement.
     -----------------

     Seller authorizes Purchaser's agents and employees to enter the Property
upon two (2) business days' prior notice to Seller (which notice may be
telephonic) before the Closing Date for the purpose of making such inventories,
examinations and audits of the Property, and of the books and records of the
Property, as Purchaser reasonably deems necessary in order to make the
adjustments and prorations required under this Article 9, or under any other
                                               ---------
provisions of this Agreement, and to determine which items of Personal Property
are excluded from this transaction and are to be retained by Seller or are
subject to payment by Purchaser or proration between Purchaser and Seller in
accordance with the terms of this Agreement.  Based upon such audits and
inventories made by both Purchaser and Seller, at or before the Closing, the
Title Company shall prepare, subject to Seller's and Purchaser's review and
approval, a closing statement (the "Closing Statement") which will show the net
                                    -----------------
amount due either to Seller or to Purchaser as the result of the adjustments
contemplated herein, and such net due amount will be added to or subtracted from
the payment of the cash balance of the Purchase Price to be paid to Seller
pursuant to Article 3 hereof.  The adjustments, prorations and determinations
            ---------
agreed to by Seller and Purchaser shall be conclusive and binding on the parties
hereto.

9.3  Calculations.
     ------------

     Subject to the provisions of Section 9.1(a) above and solely for purposes
                                  --------------
of calculating prorations, Purchaser shall be deemed to be entitled to the
Property and, therefore, entitled to the income therefrom and responsible for
the expenses thereof for the entire day upon which Closing occurs.  All such
prorations shall be made on the basis of the actual number of days of the year
and month which shall have elapsed as of the Closing Date.  Except as set forth
herein, all items of income and expense for the period after Closing will be for
the account of Purchaser, all as determined by the accrual method of accounting
in accordance with generally accepted accounting principles consistently
applied.  Bills received after Closing which relate to expenses incurred,
services performed, and any and all amounts allocable to the period prior to
Closing, shall be paid by Seller and amounts received (including, without
limitation, refunds and insurance proceeds) relating to the period prior to the
Closing shall be paid to Seller.

9.4  Survival.
     --------

     The provisions of this Article 9 shall survive the Closing.

                     CONDITIONS TO PURCHASER'S OBLIGATIONS

documents and instruments required under Article 8 is subject to the following
                                         ---------
conditions (which may be waived by Notice from Purchaser):

          (a) Purchaser shall have received from Seller all of the items

             --------------
Purchaser;

          (b) all of the representations set forth in Section 5.1 shall be true
                                                      -----------

<PAGE>

Title Company to issue any endorsements, Purchaser shall pay any costs
associated with such endorsements;

          (e) All covenants and agreements which are required to be performed by
Seller on or before Closing shall have been duly and timely performed and

          (f) Between the Due Diligence Approval Date and the Closing Date,
there shall not have occurred any event or change in the Property which results

there shall not have occurred any event or change in the Property which results
in the introduction of any hazardous substance or hazardous materials as defined
by federal, state or local law, provided, however, that Seller shall be
permitted to introduce to the Property such materials as reasonably and commonly
used, and only in such quantities as reasonably and commonly used, in the
operation of an office building complex such as the Property, provided, however,
that such materials are used in accordance with all applicable laws.

          If the conditions described above have not been fulfilled on or before
the Closing Date, then this Agreement may be terminated at Purchaser's sole
option, by written notice from Purchaser to Seller delivered on or before the
Closing Date, in which event  both the Initial Deposit and the Additional
Deposit, together with interest accrued thereon, shall be returned to Purchaser.
If no such termination notice is timely delivered to Seller, the foregoing
conditions shall be deemed satisfied or waived by Purchaser.

                                  ARTICLE XII

                    ACTIONS AND OPERATIONS PENDING CLOSING

          Seller agrees that, between the date of this Agreement and the Closing
Date:

          (a) Seller shall continue to operate and maintain the Property
substantially in accordance with the present standards.

          (b) Until the Closing Date, Seller shall maintain or replace in the
ordinary course of business all Personal Property associated with the Property
and shall not sell, transfer, encumber or permit the sale, transfer or
encumbrance of any such Personal Property except in the ordinary course of
business, unless such Personal Property so removed is replaced with new Personal
Property of similar quality and utility.

          (c) Seller shall maintain all Contracts and Permits in full force and
effect, and in the ordinary course of business timely make all payments and
observe and perform all material

                                      24.
<PAGE>

obligations to be paid, observed or performed by Seller thereunder. Seller shall
renew or replace with reasonably comparable service the Contracts which expire
prior to the Closing Date, unless Purchaser requests in writing that they not be
extended, renewed or replaced after being given reasonable notice of the
expected expiration of the Contracts, which requests shall not be unreasonably
made.

          (d) After the expiration of the Inspection Period, assuming that
Purchaser has not terminated the Agreement, Seller shall not enter into any new
Permits, Contracts or leases not subject to termination or cancellation by
Seller by the expiration of the term of the Master Lease, materially modify or
renew any existing Contracts or leases to extend beyond the term of the Master
Lease, without the prior written consent of Purchaser.  Purchaser will not
unreasonably withhold, delay or qualify any consent requested by Seller under
this subparagraph (b), and if Purchaser shall fail to give Notice of consent or
disapproval of any such matter within five (5) business days after request
therefor from Seller, then Purchaser shall be deemed to have consented thereto.

          (e) Seller shall execute and Purchaser, where necessary, shall join in
the execution of, all applications and instruments required in connection with
the transfer of all Permits (other than Excluded Permits) in order to transfer
the benefits of such Permits to Purchaser on or prior to the Closing Date.
Purchaser shall be responsible for, and pay promptly upon Seller's request, all
costs related to such applications and instruments.  Seller, subject to the next
succeeding sentence, shall use its best efforts to preserve in full force and
effect all existing Permits and to cause all those expiring to be renewed prior
to the Closing Date.  If any such Permit shall be suspended or revoked, Seller
shall promptly so notify Purchaser and shall take all measures necessary to
cause the reinstatement of such Permit without any additional limitation or
condition.

          (f) Seller shall maintain in effect all policies of casualty and
liability insurance or similar policies of insurance, with no less than the
limits of coverage now carried with respect to the Real Property.

                                 ARTICLE XIII

                            CASUALTIES AND TAKINGS

13.1 Casualties.
     ----------

          (a) Materiality Threshold.  For purposes of this Section, "material"
              ---------------------
shall mean damage or destruction of the Property ("Casualty") for which the
aggregate estimated cost of repair, restoration and rehabilitation (including
all indirect and incidental costs and expenses), determined by Purchaser in its
reasonable discretion, is in excess of Seven Hundred Fifty Thousand and 00/100
Dollars ($750,000.00).

          (b) Notice.  Seller shall give Purchaser prompt written notice of any
              ------
damage or destruction of the Property, without regard to the extent of such
damage or destruction, which

                                      25.
<PAGE>

notice shall specify the damage and the Seller's estimated cost of repair,
restoration and rehabilitation, including all indirect and incidental costs and
expenses (the "Casualty Notice").

          (c) Material Loss from Casualty.  If, prior to Closing, any portion of
              ---------------------------
the Property is damaged or destroyed to a "material" degree, Purchaser may, at
its option, terminate this Agreement by delivery of written notice of such
termination (the "Casualty Termination Notice") to Seller within fifteen (15)
business days after receipt of the Casualty Notice.  If damage or destruction
occurs within fifteen (15) business days prior to the Closing Date, such Closing
Date shall be extended to the date which is fifteen (15) business days after the
receipt by Purchaser of the Casualty Notice.  If Purchaser elects not to so
terminate this Agreement then, (i) prior to the Closing, Seller will not settle
the loss or otherwise irrevocably bind Purchaser to an award without Purchaser's
consent, which consent shall not be unreasonably withheld, conditioned or
delayed, and (ii) Purchaser shall have the exclusive right to settle the loss
and to receive all proceeds of the casualty insurance covering the Improvements
so damaged or destroyed.

          (d) Minor Loss from Casualty. If, prior to Closing, any portion of the
              ------------------------
Property is damaged or destroyed, but such damage or destruction is not
"material," Seller shall use commercially reasonable efforts to restore, prior
to Closing, the Property to its previous condition.  If Seller is unable to
complete said restoration of the Property to its previous condition prior to the
Closing, then Purchaser shall accept an assignment from Seller to Purchaser of
all of Seller's rights with respect to the settlement of all insurance proceeds
receivable with respect to such damage or destruction and shall receive a
proration credit at Closing equal to all deductibles therefrom (but not in
excess of the amount of the cost of repair).

          (e) Termination.  If Purchaser elects to terminate this Agreement
              -----------
pursuant to this Section 13.1, both the Initial Deposit and the Additional
                 ------------
Deposit (if made), together with interest accrued thereon, shall be returned to
Purchaser.

13.2 Taking.
     ------

     In the event that Seller has knowledge of the actual or threatened taking
of all or any part of the Real Property by exercise of right of eminent domain,
Seller will give Purchaser prompt written notice (a "Condemnation Notice") of
                                                     -------------------
such event.  If, on or before the Closing Date, any Real Property shall be taken
or threatened to be taken by exercise of right of eminent domain, or there shall
be taken or threatened to be taken so material a part thereof that, in the
reasonable opinion of Purchaser, the taking does or would materially interfere
with the economic operation or use of the Property, then Purchaser may elect to
terminate this Agreement by giving Seller Notice to such effect by the earlier
to occur of (a) the Closing Date, or (b) ten (10) days after Seller has given
Purchaser the Condemnation Notice.  In the event that Purchaser elects to
terminate this Agreement pursuant to this Section 13.2, both the Initial Deposit
                                          ------------
and the Additional Deposit (if made), together with interest accrued thereon
prior to the termination of the Inspection Period, shall be returned to
Purchaser.  If Purchaser does not elect to terminate this Agreement, then the
Closing shall take place as herein provided without any abatement of the
Purchase Price, and Seller shall, by written instrument at the Closing, assign
to Purchaser all of Seller's right, title and interest in and to any
condemnation award which may be payable to Seller

                                      26.
<PAGE>

on account of such condemnation without recourse. If, prior to the Closing Date,
all or any portion of the Real Property shall be taken by exercise of right of
eminent domain in a manner which does not give Purchaser the right to terminate
this Agreement, the transaction contemplated hereby shall take place as provided
in the preceding sentence. For purposes of this Section 13.2, the term "taking"
                                                ------------
shall include temporary as well as permanent takings, and a taking shall not be
deemed to be "threatened" unless and until a fund for the payment of the
anticipated compensation for such taking shall have been appropriated or some
official action with respect to such taking shall have been taken by a
governmental body possessing powers of eminent domain.

                                  ARTICLE XIV

                              ESCROW INSTRUCTIONS

          (a) Immediately after execution of this Agreement, Purchaser and
Seller shall open an escrow account with Escrow Agent.  The transactions
contemplated by this Agreement shall be completed through Escrow Agent.  This
Agreement, together with Escrow Agent's standard form provisions and any
additional restrictions not inconsistent with this Agreement as may be
reasonably required by Escrow Agent, shall constitute joint escrow instructions
to Escrow Agent regarding this matter.

          (b) In the event that the Closing hereunder shall occur, all interest
accruing on the Initial Deposit and Additional Deposit shall thereupon be paid
to Seller (with appropriate credit to Purchaser on the Settlement Statement).
Such interest shall otherwise be payable to the party entitled to receive the
Initial and Additional Deposits pursuant to this Agreement.

          (c) If disbursement from the Escrow Agent is requested at any time
other than at the Closing, notice thereof shall be given by the requesting party
to the non-requesting party, their respective attorneys, and the Escrow Agent.
Such notice shall detail the basis for the request and shall be given by
certified mail, return receipt requested, and the Escrow Agent shall not make
any disbursement pursuant to (b) above until five (5) business days after
receipt by the Escrow Agent of such notice and only if the Escrow Agent shall
not receive notice disputing such payment prior to the expiration of said five
(5) business days.

          (d) The Escrow Agent, in its sole discretion, may at any time deposit
the Initial Deposit and the Additional Deposit (if made) and any accrued
interest with a court of competent jurisdiction selected by it in its capacity
as Escrow Agent, and, in such event, the Escrow Agent shall be fully released
and discharged from all liabilities and responsibilities in connection with
holding the Initial Deposit and the Additional Deposit (if made).

          (e) The duties of the Escrow Agent are only as herein specifically
provided and are purely ministerial in nature and the Escrow Agent shall incur
no liability whatever with respect thereto, provided the Escrow Agent has acted
in good faith.

                                      27.
<PAGE>

          (f) The Escrow Agent is executing this Agreement solely to confirm
that it will hold the Initial and Additional Deposits in escrow pursuant to the
provisions of this paragraph.

          (g) The parties hereto acknowledge that the Escrow Agent is acting
solely as a stakeholder at their request and that the Escrow Agent shall not be
deemed to be an agent of either of the parties in any action that it shall take
in its capacity as Escrow Agent.  The Escrow Agent shall not be liable for any
action or omission on its part unless such action is taken or suffered as the
result of the willful misconduct or gross negligence of the Escrow Agent.   The
Escrow Agent will incur no liability for acting upon any instruction, notice,
receipt or document believed by it to be genuine and to have been made, signed,
sent or presented by a person or persons authorized to perform such acts.  The
Escrow Agent shall be under no duty to obtain the highest rate of interest upon
the deposit to be placed in escrow.

                                  ARTICLE XVI

                                    DEFAULT

          (a) Purchaser and Seller agree that it will be difficult or impossible
to ascertain Seller's damages in the event of a default by Purchaser hereunder,
and that the Initial Deposit and the Additional Deposit (if paid) represents a
fair and reasonable estimate thereof.  Therefore, if Seller shall fully perform
its obligations hereunder, and Purchaser shall fail or refuse to perform  its
obligations as required by the terms hereof, the sole remedy of the Seller shall
be to retain the Initial Deposit and the Additional Deposit (if paid) as
liquidated damages and not as a penalty and Purchaser's liability hereunder
shall be limited to the Initial and Additional Deposits and neither party hereto
shall have any further liability to the other hereunder, except for Purchaser's
surviving obligations under Section 4(a) hereof.

          (b) If Purchaser shall fully perform its obligations hereunder and if
Seller shall fail or refuse to perform its obligations hereunder, Seller's
liability for damages shall be expressly limited to the return of the Initial
Deposit and the Additional Deposit (if paid) (together with all interest
accruing thereon) to Purchaser and the reimbursement of Purchaser for all
reasonable costs of title examination, survey costs, reasonable legal fees and
any fees and expenses actually incurred by or on behalf of Purchaser in
connection with the transactions contemplated hereunder, provided that Seller's
obligations shall not exceed Fifty Thousand Dollars and 00/100 ($50,000) in the
aggregate. Alternatively, Purchaser shall have the right to specific performance
of this Agreement.  The foregoing remedies of damages or specific performance
shall be Purchaser's sole remedies available.

thereof, without the required consent of any other party thereto, would
constitute a breach thereof or in any way affect the rights of Purchaser or
Seller thereunder.  The parties shall use commercially reasonable efforts to
obtain the consent of any such third party to  the foregoing to the transfer or
assignment thereof to Purchaser in all cases in which such consent is required
for such transfer or assignment.  If such consent is not obtained, the parties

          (c) The parties recognize and acknowledge that in the event of a
breach of this Section 17.16 will cause irreparable and material loss and damage
               -------------
to the non-breaching party as to which it will not have an adequate remedy at
law or in equity.  Accordingly, each party acknowledges and agrees that the
issuance of an injunction or other equitable remedy is an appropriate remedy for
any such breach.

                                      33.
<PAGE>

          (d) Notwithstanding the foregoing provisions of this Section 17.16,

Purchaser the fact that Seller has entered into an agreement for the sale of the
Property, and (ii) Seller shall not disclose to any Back-Up Purchaser or to any

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

       Except as set forth herein, all rights, powers and remedies herein given
to Purchaser and Seller are cumulative and not alternative, and are in addition
to all statutes or rules of law. All agreements and covenants hereunder shall be

of this Agreement.

       This Section 17.26 shall govern any inconsistent provision of this
Agreement.  In the event of the termination of this Agreement and the Initial
Deposit and/or the Additional Deposit are to be returned to Purchaser, neither
the Initial Deposit nor the Additional Deposit (as applicable) shall be returned
to Purchaser until the following conditions are satisfied:  (i) Purchaser
executes and delivers a purchase agreement cancellation instrument reasonably
satisfactory to Seller; and (ii) Purchaser pays any and all amounts to be paid
in connection with Purchaser's Reports, if the failure to pay the same may
subject Seller or the Property to any liability or liens, and Purchaser provides
Seller with paid receipts and lien waivers (if applicable) for the same; and
(iii) Purchaser has delivered to Seller true and complete copies of all of
Purchaser's Reports and other written materials pertaining to its due diligence;
however, this subsection (iii) shall apply only if Seller is obligated to pay

17.28  Assignment of Foothill Loan.
       ---------------------------

       Seller hereby consents to Purchaser and Purchaser's lender contacting
Foothill Capital Corporation in connection with a possible partial assignment of
the Foothill Loan (as hereinafter defined) from Foothill to Purchaser's lender.
As used herein, the "Foothill Loan" shall mean that certain loan by Foothill to
Seller pursuant to that certain Loan and Security Agreement and that certain
Mortgage with Power of Sale, Assignment of Rents, Security Agreement and Fixture
Filing (the "Mortgage"), each dated as of July 16, 1999.  Purchaser understands
and acknowledges that although the lien of the Mortgage against the Property is
to be released in conjunction with the Closing, the Foothill Loan will not be
paid in its entirety as of the Closing and that Seller intends to continue to
utilize the Foothill Loan as an ongoing line of credit pursuant to said Loan and
Security Agreement.  Accordingly, Seller does not hereby make any representation
regarding the practicability or feasibility of any such partial assignment, even
if the same is otherwise acceptable to all parties thereto.  Purchaser shall
cause any such assignment to be conditioned upon Seller being fully released of
liability under and in connection with that part of the Foothill Loan to be
assigned.  Purchaser shall reimburse Seller for any and all costs and expenses
incurred by Seller, including but not limited to attorneys' fees, incurred in
connection with its cooperation, facilitation and execution of documents in
connection with such assignment.  Purchaser shall make such reimbursement to
Seller upon the earlier of the Closing or ten (10) days after written request
therefor by Seller.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first set forth above.

their respective counsel will rely on this Certificate in connection with the
acquisition and financing of the premises located at 655 Lone Oak Parkway,

     1. Lease. The undersigned, on behalf of itself and its wholly-owned

Capitalized terms used herein but not defined herein shall have the meaning
given to such terms in the Lease. Except with respect to the proposed amendment
to the Lease, a true, complete and correct copy of which is attached hereto as
Exhibit A-2, the Lease is the entire agreement between Landlord (or any
affiliated party) and Tenant (or any affiliated party) pertaining to the
Premises (as defined herein). There are no modifications, amendments,
supplements, renewals or assignments of the Lease. The Lease is in full force
and effect in accordance with its terms. There are no other oral or written side
agreements, representations or warranties by Landlord, which entitle Tenant to
payments or credits from Landlord or which entitle Tenant to expand or contract
the Premises or to extend or contract the term of the Lease. The Lease has been
duly executed and delivered by, and is a binding obligation of, Tenant.

     2. Leased Premises. The premises covered by the Lease (the "Premises")

the Lease. Any and all Demising Improvements required or desired in connection
with the vacating by Tenant of Building A and Building E have been completed and
paid for in full, except for approximately $40,000. Exhibit B sets forth a
complete description of any and all such Demising Improvements.

     3. Term of Lease. The Lease commenced on March 4, 1999 and, unless
otherwise terminated in accordance with the terms of the Lease or unless Tenant
exercises its early termination rights as set forth in Article 2, will expire on

     4. Rents. (a) The present amount of monthly Base Rent payable under the
Lease is $325,796.00 and has been paid in full through August 31, 1999. (b) In

tenant improvements, contributions or other concessions have been granted to
Tenant; Landlord is not reimbursing Tenant or paying Tenant's rent obligations
under any other lease; and Tenant has not advanced any funds for or on behalf of
Landlord with respect to Landlord's obligations under the Lease for which Tenant
has a right of deduction from, or set off against, future rent payments under
the Lease.

     8. No Landlord Defaults. All obligations of Landlord under the Lease have
been performed, and, to the best of Tenant's knowledge, no event has occurred
and no condition exists that, with the giving of notice or lapse of time or
both, would constitute a default by Landlord under the Lease. To Tenant's
knowledge, there are no offsets or defenses that Tenant has against the full
enforcement of the Lease by Landlord.

     9. No Tenant Defaults. Tenant is not in any respect in default under the
Lease and has not assigned, transferred or hypothecated the Lease or any
interest therein or subleased all or any portion of the Premises. Tenant is not
insolvent and is able to pay its debts as they mature. Tenant has not declared
bankruptcy or filed a petition seeking to take advantage of any law relating to
bankruptcy, insolvency, reorganization, winding-up or composition or adjustment

has been commenced against Tenant seeking such relief, and Tenant has no
knowledge that any such proceeding is threatened.

not be deemed to affect the rights and obligations of Landlord and Tenant under
any other document to which Landlord and Tenant are a party.

amendments of the Lease will be enforceable unless the modification or amendment
has been consented to in writing by the Purchaser and Lender.

     14. No Assignments. Tenant has no notice of any assignment of the Lease by
Landlord, or any assignment, hypothecation or pledge of rents accruing under the
Lease by Landlord.

this Lease together with the payment of the First Installment an amount equal to
the pro-rated amount of Fixed Rent for the number of days remaining in the month
in which the Commencement Date occurs.  The term "Lease Year" shall mean the
twelve (12) month period commencing on the Commencement Date (if that date is
the first day of a month) or commencing on the first day of the month

     under this Lease or under any other agreement at the time existing between
     Landlord and Tenant;

               (vi)   any claim as a result of any other business dealings of

     readjustment, composition, dissolution, winding up or similar proceeding
     involving or affecting Landlord.


SECTION 5.3

     Tenant shall also pay, as additional rent, all Impositions and all sums,
costs, expenses and other payments which Tenant under any of the provisions of
this Lease assumes or agrees to pay (which Impositions and all sums, costs,

have all the rights and remedies provided herein or by law in the case of
nonpayment of Fixed Rent.

SECTION 5.4

     This Lease is a net lease and the Fixed Rent shall be absolutely net to
Landlord (except for Landlord's administrative and internal costs), so that this

<PAGE>

the Fixed Rent during the term of this Lease, and, all costs, expenses and
obligations of every kind and nature whatsoever relating to the Demised Premises
which arise and are attributable to the ownership, operation, use and/or
occupancy of the Demised Premises during the term of this Lease shall be paid by
Tenant and Tenant shall indemnify and save Landlord harmless against the same.

SECTION 5.5

     Unless and until an Event of Default shall occur hereunder, Tenant may pay
the Fixed Rent by unendorsed check payable to Landlord, subject to collection;
provided, however, that, from and after the occurrence of any Event of Default
- --------  -------
and whether or not the same may thereafter be cured, Landlord may, by notice to
Tenant, thereafter require Tenant to pay the Fixed Rent by unendorsed certified
or official bank check payable to Landlord drawn on a bank or trust company
reasonably acceptable to Landlord in which event Tenant may elect to pay by such
check or by wire transfer of immediately available federal funds to an account
designated by Landlord.

SECTION 5.6

          (a) Tenant shall deposit with Landlord upon the earlier to occur of
(i) a default by SGI under the SGI Lease or (ii) the later to occur of (aa) the
expiration of the SGI Lease or (bb) July 1, 2001, an amount equal to One Million
Four Hundred Thousand One Hundred Seventy-Two and 00/100 Dollars
($1,442,172.00), referred to herein as the "Security Deposit Amount".  The
Security Deposit Amount which is deposited by Tenant under this Section and any
interest and earnings thereon (the "Security Deposit") shall serve as security
for the full and faithful performance and observance by Tenant of Tenant's
covenants and obligations under this Lease, and shall be deposited in an
interest bearing account earning not less than money market rates in a bank
chosen by Landlord, and all interest thereon shall be paid monthly to Tenant.

          (b) Effective as of the date that is four (4) years from the date
hereof (the "Fourth Anniversary"), the Security Deposit Amount shall be
increased by Two Hundred Sixteen Thousand Three Hundred Twenty-five and 80/100
Dollars ($216,325.80) (the "Fourth Anniversary Supplemental Security Deposit
Amount") to One Million Six Hundred Fifty-eight Thousand Four Hundred Ninety-
seven and 80/100 Dollars ($1,658,497.80).  Tenant, on or before the Fourth
Anniversary, shall deliver to Landlord an amount equal to the Fourth Anniversary
Supplemental Security Deposit Amount.

          (c) Effective as of the date that is five (5) years from the date
hereof and each annual anniversary thereafter (each "Annual Anniversary Date"),
the Security Deposit Amount shall be increased by an amount (the "Annual
Security Deposit Supplemental Amount") equal to three and one-half percent
(3.5%) of the Security Deposit Amount for the immediately preceding Lease Year.
Tenant, on or before each Annual Anniversary Date, shall deliver to Landlord an
amount equal to the Annual Security Deposit Supplemental Amount.

          (d) Landlord may, but shall not be required to, use, apply or retain
the whole or any part of the Security Deposit to the extent required for the
payment of any Fixed Rent and

                                       8.
<PAGE>

other Additional Rent or for any sum which Landlord may reasonably expend or may
be required to expend by reason of an Event of Default whether accruing before
or after summary proceedings or other re-entry by Landlord. If Landlord shall so
use, apply or retain the whole or any part of the Security Deposit, Tenant
shall, upon demand, immediately deposit with Landlord a sum equal to the amount
so used, applied or retained. The Security Deposit together with accrued
interest thereon, less any portion of the Security Deposit to which Landlord is
entitled pursuant to the terms of this Lease, shall be paid to Tenant
immediately after the date fixed as the end of this Lease and after delivery to
Landlord of entire possession of the Demised Premises in the manner required by
the terms of the Lease.

          (e) Tenant shall have the right to furnish to Landlord, at Tenant's
sole cost and expense, in lieu of and in substitution for the whole (and not
part) of the Security Deposit, a clean, transferable, irrevocable and
unconditional letter of credit (the "Letter of Credit") drawn in favor of
Landlord on a member bank of the New York Clearinghouse Associates or such other
bank as Landlord shall have approved, in its discretion in writing, and
substantially in the form attached hereto as Exhibit B.  If Tenant furnishes to
                                             ---------
Landlord such Letter of Credit as herein provided, Landlord shall refund to
Tenant any unapplied Security Deposit held by Landlord pursuant to this Section
5.6 and shall be increased each year to the increased amount of the Security
Deposit required under this Section 5.6 at the same time as Tenant is obligated
under this Section 5.6 to increase the amount of the Security Deposit.  The
Letter of Credit shall be assignable, upon request of Landlord, to any Mortgagee
or to a successor of Landlord at no additional charge.  Tenant shall, not later
than thirty (30) days prior to the expiration of the term of the Letter of
Credit or any replacement thereof, deliver to Landlord a replacement letter of
credit (a "Replacement Letter") such that the Letter of Credit or a Replacement
Letter shall be in effect at all times after the date of this Lease until the
end of the term of this Lease and thereafter so long as Tenant (or any assignee
or subtenant of Tenant) is in occupancy of any part of the Demised Premises.
Each Letter of Credit or Replacement Letter shall be in a face amount at least
equal to the amount of the Security Deposit required pursuant to this Section
5.6.  If Tenant fails to deliver to Landlord a Replacement Letter within the
time limit set forth in this Section 5.6, Landlord may draw the full amount of
the existing Letter of Credit or Replacement Letter without notice or demand and
retain the proceeds thereof as security subject to the provisions of this
Section 5.6, until such time as the Replacement Letter is delivered, at which
time the proceeds shall be returned to Tenant.

                            PAYMENT OF IMPOSITIONS
                            ----------------------

SECTION 6.1

     Tenant shall pay as Additional Rent all (a) taxes, (b) assessments, (c)
water and sewer rents, rates and charges, whether governmental or non-
governmental, (d) excises, levies, license and permit fees and other charges of
the Governmental Authorities, general and special, ordinary and extraordinary,
foreseen and unforeseen, of any kind and nature whatsoever which at any time
during the term of this Lease may be assessed, levied, confirmed, imposed upon,
and become due and payable out of or in respect of, or become a lien on, (i) the
Demised Premises or any part

                                       9.
<PAGE>

thereof or any appurtenances thereto, (ii) the rent, income or other payments
received by Tenant or anyone claiming by, through or under Tenant (iii) upon or
against this Lease or the leasehold estate hereby created or any document to
which Tenant is a party creating or transferring any interest or estate in the
Demised Premises, (iv) any use or occupation of the Demised Premises, or (v)
such franchises as may be appurtenant to the use of the Demised Premises (all
such rent, taxes, assessments, water and sewer rents, rates and charges,
excises, levies, license and permit fees and other charges of the Governmental
Authorities and any other amounts referred to in this Section 6.1 are
hereinafter called "Impositions" and any of the same are hereinafter called an
"Imposition"), together with any penalties, interest or costs which may be
imposed thereon or added for late payment thereof. Tenant shall have the option
to pay any Impositions in installments over the longest period allowed by law,
and Tenant shall only pay such installments that become due and payable during
the Term as they respectively become due and payable.

SECTION 6.2

     Nothing herein contained shall require Tenant to pay any income and/or
excess profits, capital levy, corporate franchise, payroll, estate, succession,
inheritance, gift or transfer taxes levied or assessed by any Governmental
Authority against Landlord.  If at any time during the term of this Lease the
methods of taxation prevailing at the commencement of the term shall be altered
so as to cause the whole or any part of such taxes, assessments, rates, levies,
fees, impositions or charges now levied, or hereafter assessed or imposed on,
real estate and the improvements thereon to be levied, assessed and imposed
wholly or partially as a capital levy, or otherwise, directly on the rents
received therefrom, or if, as the result of the alteration of any such method,
any such tax, assessment, rate, levy, fee, imposition or charge, or any part
thereof, shall be measured by or based, in whole or in part, upon the Demised
Premises, the Fixed Rent or the Additional Rent and shall be imposed upon
Landlord, then all such taxes, assessments, rates, levies, fees, impositions or
charges or the part thereof so measured or based shall be deemed to be included
within the term "Impositions" for the purposes hereof to the extent that such
Impositions would be payable if the Demised Premises were the only property of
Landlord subject to such Impositions and Tenant shall pay and discharge the
same.

SECTION 6.3

     (a) Tenant, upon written request of Landlord or any Mortgagee, will furnish
to or as directed by Landlord or any Mortgagee, within twenty (20) days after
the date when any Imposition would become delinquent, true and complete copies
of official receipts of the appropriate taxing authority, or other evidence
reasonably satisfactory to Landlord or such Mortgagee, evidencing the payment
thereof.  If such official receipts are not available within twenty (20) days
after the date any Imposition would become delinquent, Tenant will furnish the
same within twenty (20) days after they are available.  This Section 6.3(a)
shall not apply if Tenant is required to make monthly deposits under Section
6.3(b).

     (b) After an Event of Default, or if required by any Mortgagee, Tenant
shall upon delivery of notice from Landlord or such Mortgagee, deposit from and
after the date of delivery of such notice with or as directed by such Mortgagee
the amount of any Impositions to be paid by Tenant pursuant to Section 6.1, (a)
ten (10) days before the same would otherwise be payable pursuant to

                                      10.
<PAGE>

Section 6.1 hereof, or (b) monthly in advance in an amount equal to one-twelfth
thereof. Landlord shall cause such monthly deposits to be deposited in an
interest bearing account earning not less than money market rates in a bank
chosen by Landlord, and all interest thereon shall be paid monthly to Tenant;
however, if Landlord is required to provide such monthly deposits to a
Mortgagee, then Landlord shall cause the Mortgagee to deposit such monthly
deposits in an interest bearing account and the interest payable to Tenant
hereunder shall be the same as the interest earned in said account. Landlord
shall cause all Impositions to be paid to the appropriate taxing authority on or
before the date due and payable.

SECTION 6.4

     Tenant shall have the right to contest the amount or validity, in whole or
in part, of any Imposition to be paid hereunder by Tenant by appropriate
proceedings diligently conducted in good faith and to seek a reduction in the
valuation of the Demised Premises assessed for tax purposes.  Tenant shall
provide Landlord with written notice of any such proceeding.  Any refund or
credit relating to Impositions for a fiscal year in which both Landlord and
Tenant were responsible for Impositions shall be apportioned between Landlord
and Tenant pursuant to ARTICLE 26.

     Landlord shall have the right during the last three (3) years of the term
of this Lease at its own expense after notice to Tenant to seek a reduction in
the valuation of the Demised Premises assessed for tax purposes and to
participate in any action or proceeding theretofore commenced by Tenant.

SECTION 6.5

     Landlord shall not be required to join in any proceedings referred to in
Section 6.4 hereof unless the provisions of any Law at the time in effect shall
require that such proceedings be brought by or in the name of Landlord, in which
event Landlord shall join in such proceedings or permit the same to be brought
in its name.  Landlord shall, at the request of Tenant, cooperate with Tenant in
connection with any such proceedings.  Subject to the terms and conditions of
the second paragraph of Section 6.4 above, Landlord shall not be subjected to
any liability for the payment of any costs or expenses (including those relating
to its own activity) in connection with any such proceedings, and Tenant will
indemnify and save Landlord harmless from any such costs and expenses, including
reasonable attorneys' fees incurred at any stage of such proceedings or on
appeal therefrom.  Except as otherwise provided in Section 26.1 of this Lease,
Tenant shall be entitled to any refund of any Imposition and penalties or
interest thereon received by Landlord which have been paid by Tenant, or which
have been paid by Landlord but previously reimbursed in full by Tenant.

SECTION 6.6

     Landlord appoints Tenant the attorney-in-fact of Landlord for the purpose
of making all payments to be made by Tenant pursuant to any of the provisions of
this Lease to persons or entities ("Persons") other than Landlord and for the
purposes of contesting in accordance with this Lease the amount or validity of
any Imposition.  In case any Person to whom any sum is

                                      11.
<PAGE>

directly payable by Tenant under any of the provisions of this Lease shall
refuse to accept payment of such sum from Tenant, Tenant shall thereupon give
written notice of such fact to Landlord and shall pay such sum directly to
Landlord at the address of Landlord specified pursuant to ARTICLE 38 hereof, or
at such other place as Landlord may from time to time specify by notice given
pursuant to ARTICLE 38 and to the attention of such officer or other person as
Landlord may by like notice from time to time designate to Tenant, and Landlord
shall thereupon pay such sum or cause such sum to be paid to such Person and
provide evidence of such payment to Tenant.

                            SERVICES AND UTILITIES
                            ----------------------

     Tenant shall pay or cause to be paid all charges for (i) utilities for the
Demised Premises, including but not limited to electricity, steam, water,
telephone and other communication service and cable; (ii) security system; and
(iii) new and further installations and equipment to supply the same, and Tenant
shall indemnify and hold Landlord harmless against any liability, loss, expense
or damage incurred in connection therewith.  In furtherance of the foregoing,
Tenant shall procure any and all necessary permits, licenses or other
authorizations required for the lawful and proper installation and maintenance
upon the Demised Premises of wires, pipes, conduits, tubes and other equipment
and appliances for use in supplying any such service to and upon the Demised
Premises.  Landlord shall not be required to furnish to Tenant or provide any
facilities or services of any kind, nor shall Landlord be liable for any failure
of water supply, electric current or other utilities or any security system or
service therefor, except as may be caused by acts or omissions of Landlord, its
employees, agents or contractors.

                                   INSURANCE
                                   ---------

SECTION 8.1

     Tenant, at its sole cost and expense, shall keep the Improvements insured,
during the term of this Lease, (i) against loss or damage by flood with a
sublimit of $1,000,000.00 and (ii) against loss or damage by fire, lightning,
windstorm, hail, explosion, riot and civil commotion, aircraft and vehicles,
smoke, damage or leakage of sprinkler systems now or hereafter installed,
vandalism and malicious mischief and such other casualties as are presently
included in the so-called All Risk Coverage Endorsement in an amount not less
than 100% of the "full replacement cost" of the Improvements (without regard to
and with a waiver of any depreciation thereof) containing an agreed amount
endorsement with respect to Improvements and personal property waiving co-
insurance and provisions providing for no deductible in excess of Twenty-Five
Thousand Dollars and 00/100 ($25,000) for all such insurance coverage.  Such
"full replacement cost" when applied to the Improvements, shall mean the actual
replacement cost (excluding land, excavation costs and that part of the footing
and foundation cost which is customarily not insurable under fire policies)
without regard to depreciation, and shall be determined from time to time (not
more frequently than once in any twelve (12) consecutive months), at the request
of

                                      12.
<PAGE>

Landlord, but at the expense of Tenant, by one of the insurers, a reputable
insurance broker or by an appraiser chosen by Tenant subject to the reasonable
approval of Landlord.  Landlord's failure to request such a determination shall
not relieve Tenant of its obligation hereunder.  Landlord may require Tenant to
furnish additional insurance at any time that Landlord deems such insurance to
be inadequate based upon the requirements of an owner of property similar to the
Demised Premises.

SECTION 8.2

     Tenant, at its sole cost and expense, shall maintain:

          (a) comprehensive general liability insurance including, without
limitation, contractual liability, on an "occurrence basis", (so long as all or
any risks under comprehensive liability coverage can be obtained from insurers
meeting the standards set forth in Section 8.3 hereof on an occurrence basis,
and without regard for the cost thereof) against claims for personal injury
(including without limitation bodily injury and death) or property damage,
occurring on, in or about the Demised Premises or any elevator or any escalator
therein and on, in or about the adjoining sidewalks, streets and passageways,
such insurance to afford minimum protection, during the Term, of not less than
$10,000,000 in respect of personal injury or death to any one individual and in
respect of any one "occurrence" involving any one or more individuals and for
property damage;

          (b) boiler and machinery insurance, provided the Improvements contain
equipment of the nature ordinarily covered by such a policy;

          (c) insurance covering Tenant's obligation to indemnify hereunder
Landlord and each Mortgagee;

          (d) specific excess  workers' compensation insurance including
Employer's Liability insurance in an amount not less than $5,000,000, with no
more than $10,000 self insured retention covering all individuals and other
Persons employed by Tenant in connection with the Demised Premises and with
respect to whom death or bodily injury claims could be asserted against
Landlord, Tenant or the Demised Premises;

          (e) rental income insurance covering rental income under the SGI Lease
for a period of not less than twelve (12) months;

          (f) business interruption insurance in an amount equal to not less
than $10,000,000.00 per occurrence;

          (g) vandalism and malicious mischief insurance in an amount of not
less than $1,000,000; and

          (h) such other insurance, in such amounts as may from time to time be
required by Landlord against other insurable hazards based upon the requirements
of an owner of property similar to the Demised Premises.

                                      13.
<PAGE>

     Tenant shall not violate or permit to be violated any of the conditions or
provisions of any policy provided for herein.

SECTION 8.3

     All insurance provided for in this ARTICLE shall be effected under valid
and enforceable policies in such forms and amounts as may, from time to time, be
required as herein and elsewhere specified in this Lease, issued by insurers of
recognized responsibility which are licensed to do business in the State of
Minnesota, are rated "A VII" or better by Best's Key Rating Guide or, if there
is no Best's Key Rating Guide, a comparable rating by another national rating
organization reasonably acceptable to Landlord. The aggregate limit of liability
underwritten by any insurer in conformance with the provisions of this Lease
shall not exceed 5% of that insurer's surplus to policyholders.  Upon execution
of this Lease, and thereafter not less than fifteen (15) days prior to the
expiration dates of the expiring policies theretofore furnished pursuant to this
ARTICLE, certificates of the insurers reasonably satisfactory to Landlord and,
upon request, duplicate originals of the policies involved, shall be delivered
by Tenant to or as directed by Landlord.  Each policy of insurance procured
pursuant to Section 8.1 shall contain, if obtainable, either (i) a waiver by the
insurer of the right of subrogation against Landlord for negligence of Landlord,
or (ii) a statement that the insurance shall not be invalidated should any
insured waive in writing prior to a loss any or all right of recovery against
Landlord for loss accruing to the property described in the insurance policy.
Tenant shall not carry separate or additional insurance, concurrent in form or
contributing, in the event of any loss or damage, with any insurance required to
be obtained by Tenant under this Lease.

SECTION 8.4

     All policies of insurance provided for in Sections 8.1 and 8.2 hereof shall
insure Landlord and Tenant and any Mortgagee as named insureds.  Such policies
shall also, if requested by Landlord, be made payable, subject to the provisions
of this Lease, to any Mortgagee, as its interest may appear, pursuant to a
standard mortgagee clause, its equivalent, or a loss payable clause reasonably
acceptable to Landlord and acceptable to such Mortgagee.  Landlord requests, and
Tenant acknowledges the request of Landlord, that Deutsche Banc Mortgage
Capital, L.L.C. be so named as Mortgagee under the insurance provided for in
Sections 8.1 and 8.2 hereof.  The loss, if any, under any policies provided for
in Section 8.1 and in paragraphs (b), (d) and (e) of Section 8.2 shall be
adjusted with the insurance companies (a) by Tenant, in the case of any
particular casualty resulting in damage or destruction not exceeding the
Insurance Threshold Amount in the aggregate, and provided Tenant is not in
default under this Lease (i.e. Landlord shall consent in writing and cause any
Mortgagee to consent in writing to Tenant's adjustment of any losses not
exceeding the Insurance Threshold Amount, provided Tenant is not in default
under this Lease) or (b) by Landlord, Tenant and any Mortgagee, if requested by
such Mortgagee, in the case of any particular casualty resulting in damage or
destruction exceeding the Insurance Threshold Amount in the aggregate or if
Tenant shall be in default under this Lease (regardless of the extent of the
damage or destruction).  The proceeds of any such insurance, as so adjusted,
shall be payable:

               (i)  to Tenant in the case of any particular casualty resulting
     in damage or destruction to the Improvements not exceeding the Insurance
     Threshold Amount in the aggregate, provided Tenant is not in default under
     this Lease, or

               (ii) in the case of any particular casualty resulting in damage
     or destruction exceeding the Insurance Threshold Amount in the aggregate,
     or if Tenant is in default under this Lease (regardless of the extent of
     the damage or destruction), to any Mortgagee or Mortgagees so long as
     Landlord's interest in this Lease is assigned to such Mortgagee or
     Mortgagees, or if there is no Mortgagee, then to Landlord.

     All such policies shall provide Landlord and any Mortgagee with not less
than the rights and benefits with respect to payment and adjustment provided
above in this Section 8.4.  Each policy shall contain (a) a provision that no
inadvertent act or omission of Landlord or Tenant which would otherwise result
in a forfeiture or reduction of the insurance therein provided shall affect or
limit the obligation of the insurance company so to pay in accordance with
Sections 8.4 and 8.7 of this Lease the amount of any loss sustained, (b) an
agreement by the insurer that such policy shall not be cancelled without at
least thirty (30) days prior written notice to Landlord and to any Mortgagee and
(c) an agreement by the insurer to give written notice to Landlord and any
Mortgagee if such policy has not been renewed fifteen (15) days prior to its
expiration.  The "Insurance Threshold Amount" means Five Hundred Thousand and
00/100 Dollars ($500,000.00).

SECTION 8.5

     If, at any time during the term of this Lease, Landlord or any Mortgagee
shall request that the amount of insurance required under Sections 8.1 and 8.2
hereof be increased on the ground that such coverage is inadequate properly to
protect the interest of Landlord and such Mortgagee, or if Landlord or any
Mortgagee shall require other insurance pursuant to the provisions of Section
8.1 and Section 8.2, Tenant shall thereafter carry the amount and such kind of
insurance as determined by Landlord or any Mortgagee to be adequate and
required, but in no event shall the amount of insurance under Sections 8.1 and
8.2 hereof be (i) less than the amount required by such Sections, or (ii)
materially greater than amounts typically required by landlords and mortgagees
of comparable properties in the Minneapolis - St. Paul metropolitan area.

SECTION 8.6

     Any insurance provided for in this ARTICLE 8 may be effected by a policy or
policies of blanket insurance; provided, however, that the amount of the total
                               --------  -------
insurance shall be such as to furnish in protection the equivalent of separate
policies in the amounts herein required; and provided, further that in all other
                                             --------  -------
respects, any such policy or policies shall comply with the other provisions of
this Lease.  In any such case, Tenant shall deliver to or as directed by
Landlord a certificate or duplicate of such policy.

                                      15.
<PAGE>

SECTION 8.7

     Tenant shall furnish Landlord annually, a certificate signed by an
authorized officer of Tenant containing a detailed list of the insurance
policies then outstanding and in force on the Demised Premises and stating that
such insurance complies with the requirements of this ARTICLE 8.

                                   ARTICLE 9

                             DAMAGE OR DESTRUCTION
                             ---------------------

SECTION 9.1

     In the case of any particular casualty to the Improvements resulting in
damage or destruction in excess of One Hundred Thousand and No/100 Dollars
($100,000), Tenant shall promptly give written notice thereof to Landlord.
Regardless of the amount of any damage or destruction, Tenant shall, at its sole
cost and expense, and whether or not the insurance proceeds, if any, shall be
sufficient for the purpose, either restore, repair, replace, rebuild or alter
the Improvements as nearly as possible to their value, condition and character
immediately prior to such damage or destruction substantially in accordance with
plans and specifications approved in writing by Landlord and any Mortgagee (such
approval shall not be unreasonably withheld, conditioned or delayed).  Such
restoration, repairs, replacements, rebuilding or alterations shall be commenced
promptly, and prosecuted in a good and workmanlike manner with reasonable
diligence.  Within thirty (30) days or such longer period as is reasonably
necessary after any casualty, but in no event greater than sixty (60) days after
such casualty, Tenant shall deliver to Landlord an estimate of the costs to
repair, restore and/or rebuild the Demised Premises in accordance with the terms
of this Lease, which estimate shall be prepared by a licensed contractor or
architect acceptable to Landlord (such consent shall not be unreasonably
withheld, conditioned or delayed).

SECTION 9.2

     All insurance proceeds received by Landlord or any Mortgagee, on account of
such damage or destruction, less the costs, fees and expenses, if any, incurred
in connection with adjustment of the loss, shall be applied to pay or, if Tenant
elected to make advance payments, reimburse Tenant, for the payment of the cost
of the aforesaid restoration, repairs, replacements, rebuilding or alterations,
including the cost of temporary repairs or for the protection of property
pending the completion of permanent restoration, repairs, replacements,
rebuilding or alteration (all of which temporary repairs, protection of property
and permanent restorations, repairs, replacements, rebuilding or alterations are
hereinafter collectively referred to as the "restoration"), and provided there
is no Event of Default under this Lease, shall be paid out from time to time as
such restoration progresses upon the written request of Tenant which shall be
accompanied by the following:

          (a)  A certificate signed by Tenant, dated not more than five (5) days
prior to such request, setting forth the following:

                                      16.
<PAGE>

               (i)    that the sum then requested either has been paid by
     Tenant, or is justly due to contractors, subcontractors, materialmen,
     engineers, architects or other Persons who have rendered services or
     furnished materials for the restoration therein specified, the names and
     addresses of such Persons, a brief description of such services and
     materials, the several amounts so paid or due to each of such Persons in
     respect thereof, that no part of such expenditures has been or is being
     made the basis, in any previous or then pending request, for the withdrawal
     of insurance money or has been made out of the proceeds of insurance
     received by Tenant, and that the sum then requested does not exceed the
     value of the services and materials described in the certificate;

               (ii)   that on the date of Tenant's certificate, except for the
     amount, if any, stated pursuant to the foregoing subclause (a)(i) in such
     certificate to be due for services or materials and any retainage permitted
     under the agreement with the contractor, there is no outstanding
     indebtedness known to the Tenant, after due inquiry, which is then due for
     labor, wages, materials, supplies or services in connection with such
     restoration; and

               (iii)  that on the date of Tenant's certificate the cost, as
     estimated by Tenant, of the restoration required to be done subsequent to
     the date of such certificate in order to complete the same, does not exceed
     the insurance money, plus amounts otherwise available to Tenant, after
     payment of the sum requested in such certificate;

          (b)  A title company or official search, showing that there have not
been filed with respect to the Demised Premises, any vendor's, contractor's,
mechanic's, laborer's or materialman's statutory or similar lien which has not
been discharged of record, except such as will be discharged upon payment of the
sum requested in such certificate; and

     In the event the total cost of the restoration exceeds the Insurance
Threshold Amount at the time the certificate is delivered, the certificate
required by clause (a) of this Section 9.2 shall be signed also by an
independent licensed architect and/or engineer, who shall be in charge of the
restoration and shall be selected by Tenant and approved in writing by Landlord.

     Upon compliance with the foregoing provisions of this Section 9.2, there
shall be paid or caused to be paid out of such insurance money to Tenant or the
Persons named pursuant to subclause (a)(i) of this Section 9.2 in such
certificate the respective amounts stated therein to have been paid by Tenant or
be due to them, as the case may be.

     If the insurance money at the time available for the purpose, less the
actual costs, fees and expenses, if any, incurred in connection with the
adjustment of the loss, shall be insufficient to pay the entire cost of such
restoration, Tenant shall pay the deficiency.  Any such deficiency shall be paid
by Tenant prior to application of the insurance money.

     Upon receipt by Landlord, or the Mortgagee, of the items required by
clauses (a) and (b) of this Section 9.2 evidencing that the restoration has been
completed and paid for in full and that there are no liens of the character
referred to herein or right to obtain the same by filing, and provided (i)
Lessor shall be reasonably satisfied that sufficient funds are available to
complete the restoration, and (ii) Tenant is not in default under this Lease,
any balance of the insurance

                                      17.
<PAGE>

money held by Landlord or the Mortgagee shall be paid to Tenant. Notwithstanding
any contrary or inconsistent provision in this Lease, regardless of (i) Tenant's
default hereunder; or (ii) Tenant's satisfaction of any of the provisions
contained in Article 9, upon closing of the re-purchase by Tenant pursuant to
Article 47 below, Article 48 below, or otherwise, Landlord shall simultaneously
assign, transfer and pay over to Tenant any and all insurance proceeds and
related rights and benefits less any reasonable out-of-pocket costs theretofore
incurred in connection with receiving such proceeds.

     If, notwithstanding the provisions of this Article 9, Landlord or the
Mortgagee is entitled to receive the insurance proceeds but Tenant instead
receives such insurance proceeds, Tenant shall hold such insurance proceeds in
trust and shall immediately cause such insurance proceeds to paid to Landlord or
the Mortgagee, as required under this Article 9.

SECTION 9.3

     No destruction of or damage to the Demised Premises or any part thereof by
fire or any other casualty shall terminate or permit Tenant to surrender this
Lease or shall relieve Tenant from its liability to pay the Fixed Rent,
Additional Rent and other charges payable under this Lease or from any of its
other obligations under this Lease, and Tenant waives any rights now or
hereafter conferred upon it by statute or otherwise to quit or surrender this
Lease or the Demised Premises or any part thereof, or to any suspension,
diminution, abatement or reduction of rent on account of any such destruction or
damage.  No destruction of or damage to the Demised Premises or any part thereof
by fire or any other casualty shall terminate or permit Landlord to terminate
this Lease or shall relieve Landlord from its obligations under this Lease.

SECTION 9.4

     If insurance proceeds are received by Landlord and paid out to Tenant as
provided in Section 9.2, Tenant shall pay the reasonable fees and expenses of
any third Person architect or engineer engaged by and reasonably required by
Landlord, in its judgment, to review any plans and specifications prepared by
Tenant and to inspect any work performed by Tenant under this ARTICLE 9 and any
other reasonable out-of-pocket expenses incurred by Landlord in review of such
plans and specifications and inspection of such work.  However, Tenant's
obligations under this Section 9.4 shall in no event exceed Seven Thousand Five
Hundred Dollars ($7,500.00) per casualty.

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

SECTION 10.1

     Tenant hereby assigns to Landlord any award, payment or compensation to
which it may be or become entitled during the term of this Lease by reason of
any taking of the Demised Premises or a part thereof, in or by condemnation or
other eminent domain Proceeding pursuant to any law, general or special, or,
except as otherwise provided in Sections 10.3 and 10.4, by

                                      18.
<PAGE>

reason of the temporary requisition of the use or occupancy of the Demised
Premises or a part thereof, by any Governmental Authority whether the same shall
be paid or payable in respect of Tenant's leasehold interest hereunder, provided
that such award, payment or compensation and any interest or income earned
thereon shall be applied as hereinafter provided for in this ARTICLE 10.
Landlord and Mortgagee shall be entitled to participate in any such Proceedings
and if Landlord participates therein, Landlord shall pay all costs and expenses,
including fees of attorneys, appraisers, architects and engineers, incurred by
Landlord in so participating. Tenant shall not be liable for any such costs or
expenses incurred by Landlord or Mortgagee. Notwithstanding the foregoing
provisions of this Section 10.1, Tenant shall have the right to make a separate
claim in condemnation or other eminent domain Proceedings solely for the loss of
all or part of its leasehold estate, and for its removal expenses, value of the
leasehold, value of Tenant's fixtures, and relocation expenses as a result of
such Proceeding. No claim may be made by Tenant in any such Proceeding and
Tenant shall not be entitled to any award, payment or compensation for the cost
of any demolition, repairs and replacement required as a result of any such
Proceeding or for the cost of any of Tenant's leasehold improvements.

SECTION 10.2

     If, during the term of this Lease, all or substantially all of the Demised
Premises shall be taken in or by condemnation or other eminent domain Proceeding
pursuant to any Law, general or special, then this Lease and all right, title
and interest of Tenant hereunder shall terminate as of the date that title to
the Demised Premises shall vest in accordance with such Proceeding.  If
substantially all (but not all) of the Demised Premises is so taken and Landlord
disputes Tenant's exercise of its right to so terminate this Lease, and the
resolution of the dispute is that Tenant had the right to so terminate the
Lease, then such termination shall occur as of the termination date specified in
such notice by Tenant, provided that Tenant has vacated the Demised Premises on
or before such date.  In the event that this Lease shall so terminate or be
terminated, the Fixed Rent and the Additional Rent shall be appropriately
apportioned as of the date of such termination.  Any dispute by Landlord or
Tenant under the provisions of this Section 10.2 shall be resolved by
arbitration in the manner provided in Section 10.5.  For purposes of this
Section, substantially all of the Demised Premises shall be deemed to have been
taken if the portion of the Demised Premises not so taken, taking into
consideration the amount of the award available for such purpose, cannot in the
reasonable opinion of Landlord and Tenant be so repaired or reconstructed as to
constitute a facility suitable for all of the uses permitted hereunder.

SECTION 10.3

     If, during the term of this Lease, any portion of the Demised Premises
shall be taken in or by any such Proceeding and this Lease shall not terminate
or be terminated pursuant to Section 10.2 hereof, then this Lease shall continue
in full force and effect, and Tenant's obligation to pay the Fixed Rent,
Additional Rent and all other charges on the part of Tenant to be paid and to
perform all other covenants and agreements on the part of Tenant to be performed
shall not be affected by any such taking of the Demised Premises, and Tenant
hereby waives the provisions of any Laws now or hereafter in effect contrary to
such obligation of Tenant or which relieves Tenant therefrom to pay costs of
demolition, repair and restoration required as a result of the taking in any
such Proceeding.  Landlord shall deliver such award to Tenant if such costs are

                                      19.
<PAGE>

estimated to be less than the Insurance Threshold Amount provided Tenant is not
in default under this Lease.  If such costs are estimated to exceed the
Insurance Threshold Amount, or if Tenant is in default under this Lease
regardless of such costs, such award shall be retained by Landlord, or shall be
applied by Tenant, if delivered to Tenant, and paid over to Tenant if delivered
to any Mortgagee or Landlord, to be applied in the manner provided in Section
9.2, for the cost of demolition, repair and restoration, if any, required as a
result of the taking in any such Proceeding, which demolition, repair and
restoration shall be undertaken by Tenant in substantially the same manner as
required in Section 9.1 hereof.  Any balance of such award remaining after
payment of such costs of demolition, repair and restoration shall be retained by
Landlord.  If any portion of the Demised Premises shall be taken in or by any
condemnation or other eminent domain Proceeding and this Lease shall not
terminate or be terminated, then the Purchase Option Price and the Put Option
Price shall be reduced by an amount equal to the portion of any award received
by Landlord in connection with such Proceeding.  The Purchase Option Price and
the Put Option Price shall not, however, be reduced by the amount of any award
received by Tenant under Section 10.4 hereof for any temporary taking.  Tenant
shall have the right provided in Section 10.1 to make a separate claim for its
own award solely for loss of all or part of its leasehold estate and its removal
expenses and relocation expenses, but not for its leasehold improvements (which
shall be considered only in valuing Tenant's leasehold estate.)

SECTION 10.4

     If, during the term of this Lease, the temporary use or occupancy of all or
part of the Demised Premises shall be taken in or by such Proceeding or in any
other manner for any public or quasi-public use or purpose or by agreement
between Landlord and those authorized to exercise such right, then, if the
period of temporary use is totally within the term of this Lease, the sums
awarded or made available as a result of such temporary taking shall be paid to
Tenant and that portion of the award which represents reimbursement for the cost
of restoration of the Demised Premises as reasonably estimated by an independent
licensed architect or engineer chosen by Landlord and reasonably acceptable to
Tenant, and engaged at the expense of Tenant, shall be applied by Tenant toward
the cost of its restoration of the Demised Premises.  In addition, Tenant shall
be entitled to receive that portion of the award which represents compensation
for the taking of Tenant's personal property (if any, and only to the extent
that Tenant's personal property is so taken) and for relocation expenses if
Tenant is required to relocate, and Tenant shall be entitled to a credit against
Fixed Rent of that portion of the award or payment which represents compensation
for the use and occupancy of the Demised Premises.  If the period of temporary
use is not totally within the term of this Lease, or if it is not possible to
determine whether it is totally within the term of this Lease, then the sums
awarded or made available as a result of such temporary taking shall be paid to
Landlord and shall be applied in the following order of priority: (a) first,
Landlord shall be entitled to receive that portion of the award which represents
reimbursement for the cost of restoration of the Premises as reasonably
estimated by an independent licensed architect or engineer chosen and engaged by
Landlord and reasonably acceptable to Tenant, and Tenant shall (to the extent
feasible within the remainder of the term of this Lease) restore the Demised
Premises and Landlord shall pay over such portion of such award in the same
manner as is provided for insurance proceeds under ARTICLE 9, (b) second, Tenant
shall be entitled to receive that portion of the award which represents
compensation for the taking of Tenant's personal property and for relocation
expenses, and (c)

                                      20.
<PAGE>

third, Tenant shall be entitled to a credit against Fixed Rent of that portion
of the award or payment which represents compensation for the use and occupancy
of the Demised Premises (but in no event more than the Fixed Rent due under this
Lease). This Lease shall be unaffected by such taking and Tenant shall continue
to be responsible for all of its obligations hereunder and shall continue to pay
in full the Fixed Rent, and Additional Rent when due except to the extent of the
credit provided for above. All monies paid to Landlord as, or as part of, an
award for which the Fixed Rent have been paid shall be received, held and
applied by Landlord as a trust fund for payment of the Fixed Rent becoming due
hereunder.

     Notwithstanding any contrary or inconsistent provision in this Lease,
regardless of (i) Tenant's default hereunder; or (ii) Tenant's satisfaction of
any of the provisions contained in Article 10, upon closing of the re-purchase
by Tenant pursuant to Article 47 below, Article 48 below, or otherwise, Landlord
shall simultaneously assign, transfer and pay over to Tenant any and all
condemnation award(s) and related rights and benefits.

SECTION 10.5

     In any instance in this ARTICLE 10 where this Agreement provides for
submission of a dispute or matter to arbitration (and not under any other
circumstance) the arbitration shall be conducted by the American Arbitration
Association ("AAA"), or any successor thereto, in the City of Minneapolis,
Minnesota, in accordance with its rules then obtaining and the provisions of
this Section 10.5.  The party requesting arbitration shall give written notice
to that effect to the other party, specifying in said notice the name and
address of the Qualified Arbitrator (as hereinafter defined) designated to act
as arbitrator on behalf of the requesting party.  Each arbitrator shall be an
impartial third party having experience in matters similar to the subject matter
of the dispute (a "Qualified Arbitrator").  Within fifteen (15) days after the
                   --------------------
service of such notice, the other party shall give written notice to the
requesting party specifying the name and address of a Qualified Arbitrator
designated to act as arbitrator on its behalf.  If the other party fails to
notify the requesting party of the appointment of its arbitrator within the time
specified, the second arbitrator shall be a Qualified Arbitrator appointed by
the AAA.  The arbitrators so chosen shall meet within ten (10) days after the
second arbitrator is appointed.  If, within thirty (30) days after the second
arbitrator is appointed, the two arbitrators shall not agree upon a resolution
of the dispute, they shall themselves appoint a third Qualified Arbitrator.  If
they are unable to agree upon such appointment within ten (10) days after the
expiration of said thirty (30)-day period, the third Qualified Arbitrator shall
be selected by the parties.  If the parties are unable to agree upon a third
Qualified Arbitrator within fifteen (15) days, then such third Qualified
Arbitrator shall be appointed by the AAA.  The decision of the arbitrators so
chosen shall be given within a period of thirty (30) days after the appointment
of the third Qualified Arbitrator, if a third Qualified Arbitrator is appointed,
or within thirty (30) days after the second arbitrator is appointed.  Such
decision shall be final and conclusive on Landlord and Tenant and judgment
thereon may be entered in any court of competent jurisdiction.  In acting under
this Lease, the arbitrators shall:  (i) not modify the provisions of this Lease;
and (ii) apply the applicable laws of the State of Minnesota.  The costs of the
arbitrators and of the AAA shall be paid fifty percent (50%) by Landlord and
fifty percent (50%) by Tenant.

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

SECTION 11.1

          (a) Throughout the term of this Lease, Tenant shall, at its sole cost
and expense, take good care of the Demised Premises (including the
Improvements), all alleyways and passageways and the sidewalks, curbs and vaults
adjoining the Demised Premises, and keep the same in good order, condition and
repair, ordinary wear and tear and obsolescence excepted, and make all necessary
repairs thereto, interior and exterior, structural and nonstructural, ordinary
and extraordinary, foreseen and unforeseen.  When used in this ARTICLE 11, the
term "repairs" shall include all necessary replacements, renewals, alterations
and additions and any rebuilt, additional or substituted buildings, structures,
facilities and other improvements.  Landlord shall not be required to furnish
any services or facilities or to make any repairs or alterations in or to the
Demised Premises, Tenant hereby assuming the full and sole responsibility for
the condition, operation, repair, replacement, maintenance and management of the
Demised Premises.  All repairs made by Tenant shall be made in a good and
workmanlike manner.  The necessity for and adequacy of repairs to the
Improvements pursuant to this ARTICLE 11 shall be measured by the standards
which are generally appropriate for buildings and facilities of similar
construction, age and use.

          (b) In the event that Tenant is required pursuant to the provisions of
Section 11.1(a) during the term of this Lease or during the Renewal Options or
any extension of the term to replace the roof of any of the buildings located at
the Demised Premises, make a structural change or structural repair in any of
the buildings located at the Demised Premises or to replace all or part of the
HVAC system in any of the buildings located at the Demised Premises
(collectively, the "Capital Work") at an aggregate cost for Capital Work in any
twelve (12) month period exceeding One Hundred Seventy-five Thousand Dollars
($175,000.00), Tenant shall notify Landlord thereof.  In addition, if Tenant
desires that the cost thereof be shared by Landlord in the manner provided in
this Section 11.1(b), Tenant and Landlord shall jointly participate in and
determine the Persons to perform the Capital Work (including architects,
engineers and contractors), the plans and specifications for the Capital Work
and the cost thereof which, in hiring the contractor or contractors performing
such work, shall be determined by a bid process determined by Tenant and
reasonably acceptable to Landlord.  To the extent that the improvements
resulting from such Capital Work constitute capital improvements and which under
Generally Accepted Accounting Principles, applied consistently ("GAAP"), will
have a useful life extending beyond the term of this Lease, then Tenant may
elect by notice to Landlord that Landlord pay to Tenant as provided in this
Section 11.1(b) a portion of the cost of such Capital Work.  In the event Tenant
makes such an election and complies with the foregoing provisions of this
section, Landlord shall pay to Tenant a portion of the cost appropriately
classified as capitalized under GAAP of the improvements resulting from such
Capital Work.  Landlord's share of such costs shall be equivalent to the product
of the amount that is capitalized times a fraction, the numerator of which is
the number of years remaining in the useful life of such capital improvements at
the Trigger Date (as hereinafter defined) determined under GAAP and the
denominator of which is the total useful life of such capitalized improvement.
Such

                                      22.
<PAGE>

payment shall be made by Landlord to Tenant not later than ten (10) business
days after the date of the last to occur of the following (the "Trigger Date"):
(i) the termination of this Lease pursuant to the terms of this Lease; (ii) the
end of the term of this Lease (including any exercised Renewal Options), and
(iii) vacation by Tenant of the Demised Premises after such termination or
expiration. Landlord shall have the right to offset from the amount of such
payment any delinquent Fixed Rent or other delinquent amounts due Landlord from
Tenant. Landlord shall deliver notice of any such offset simultaneously with
delivery of such payment by Landlord. Determinations under GAAP under this
Section 11.1(b) shall be made by Tenant's independent certified public
accountants, subject to Landlord's right as hereinafter specified to dispute any
such determination. Any disputes between Tenant and Landlord under this Section
11.1(b), except disputes pertaining to an interpretation under GAAP, shall be
         ------
determined by arbitration before a single Qualified Arbitrator appointed by and
in accordance with the rules of the AAA. If Landlord disputes a determination
under GAAP, that dispute shall be determined by an accounting firm, independent
of both Landlord and Tenant, chosen by lot by Landlord and Tenant from among the
six (6) largest United States accounting firms (by numbers of employees) in the
United States. Such a determination by AAA or such accounting firm so chosen
shall be final and conclusive on Landlord and Tenant and judgment thereon may be
entered in any court of competent jurisdiction. Costs of the arbitrator, the AAA
and such accounting firm shall be paid fifty percent (50%) by Landlord and fifty
percent (50%) by Tenant. Notwithstanding the foregoing, if after requesting
reimbursement from Landlord for any Capital Work, Tenant shall exercise any of
its Renewal Options such that the entire useful life of such Capital Work falls
within the term of this Lease as so extended, Landlord shall have no obligation
to provide Tenant with any reimbursement whatsoever in connection with such
Capital Work.

SECTION 11.2

     Tenant covenants not to permit or suffer any overloading of the floors of
the Demised Premises or the electrical equipment therein contrary to the
applicable certificate of occupancy, Board of Fire Underwriters certificate or
any certificate of any insurance carrier and/or Law; however, Tenant shall not
be obligated to correct any violation described above in this Section 11.2

SECTION 11.3

     Tenant shall not remove or permit removal of any of the permanent
furnishings, fixtures or other property constituting a part of any buildings on

     Landlord shall have the right, but not the obligation, to have the Demised
Premises inspected from time to time during the term of this Lease by its
engineering and environmental consultants after providing ten (10) days prior

                                                   ---
repair by Tenant, Tenant shall cause such Required Repairs to be made as soon as
practicable after receipt of notification (the "Repair Notification") from
Landlord.  Landlord may exercise this right from time to time during the term of
this Lease but not more frequently than one (1) time in any twelve (12) month
period, except that if an Event of Default is continuing, Landlord may exercise
this right at any time during which the Event of Default continues uncured.  If
the cost of such Required Repairs is less than $15,000.00, Landlord shall pay
any and all costs and expenses (except for the cost of the Required Repairs)
incurred by Landlord in connection with the performance of the inspections and
any and all supplemental inspections performed in connection therewith.  If the
cost of the Required Repairs is $15,000.00 or more, Tenant shall, within ten
(10) business days after receipt of the Repair Notification, pay to Landlord an
amount equal to the amount of the reasonable costs and expenses incurred by or

     In connection with Tenant's obligations to maintain the Demised Premises
pursuant to terms and conditions of Article 11, Tenant shall cause to be
performed the maintenance items listed on Schedule 11.5 attached hereto as and
when required by the terms of such Schedule.  The listing of the maintenance
items on Schedule 11.5 is intended only as a partial listing of those items
required to be performed by Tenant in connection with its maintenance
obligations under this Lease and in no event shall Tenant be deemed to have
satisfied its maintenance obligations hereunder solely by the performance by
Tenant of the items listed on said Schedule.

                                  ALTERATIONS
                                  -----------

SECTION 12.1

     Tenant shall have the right at any time and from time to time during the
term of this Lease to make, at its sole cost and expense, changes, replacements,
alterations, additions, enlargements or expansions in, of or to the
Improvements, or to construct additional improvements on the Demised Premises
(all of the foregoing hereinafter collectively called "Alterations" and
individually called an "Alteration"), subject, however, in all cases to the
following:

          (a) No particular Alteration involving an estimated cost of more than
$250,000 shall be undertaken except after thirty (30) days prior written notice
to Landlord.

          (b) No particular Alteration, structural or non-structural (including
any restoration required by ARTICLE 9 or 10 herein), involving an estimated cost
of more than the Insurance Threshold Amount shall be made without the prior
written consent of any Mortgagee, if required by the terms of any Underlying
Mortgage, and of Landlord, such written consent of Landlord and

                                      24.
<PAGE>

Mortgagee shall be granted without unreasonable delay or conditions if the
Alteration would not in the reasonable opinion of Landlord adversely affect in
any way the value, rental value, rentability or usefulness of the Improvements
(taking into consideration the length of the term remaining and any exercised
extensions allowed under this Lease), the structural integrity of the
Improvements or the proper functioning of the mechanical systems therein. If
such approval is required, such Alterations will be made substantially in
accordance with plans and specifications approved in writing by any such
Mortgagee and by Landlord. Three (3) copies of plans and specifications in such
reasonable detail as will permit Landlord to exercise its judgment shall be
submitted to Landlord in connection with Alterations under this Section 12.1(b).
Notwithstanding any contrary provision in this Article 12, Landlord may in its
sole discretion withhold consent to any Alteration to the extent it entails
constructing an addition on to the Improvements and/or constructing a new
building on the Demised Premises or constructing other new improvements on the
Demised Premises outside of the currently existing exterior walls of the
Improvements.

          (c) If the estimated cost of any particular Alteration shall be in
excess of the Insurance Threshold Amount, Tenant shall pay to or as directed by
Landlord the reasonable fees and expenses of any third Person architects or
engineers selected by any Mortgagee and by Landlord to review the plans and
specifications and inspect the work on behalf of Landlord and such Mortgagee and
other out-of-pocket expenses incurred by Landlord and such Mortgagee in review
of such plans and specifications and inspection of such work.  However, Tenant
shall not be obligated to pay more than Seven Thousand Five Hundred Dollars
($7,500.00) for such review and inspection work.

                                      25.
<PAGE>

          (d) No Alteration shall be undertaken until Tenant shall have procured
and paid for, so far as the same may be required from time to time, all permits
and authorizations of the Governmental Authorities.  Landlord shall join in the
application for such permits or authorizations whenever such action is
necessary, but without any liability or expense to Landlord.

          (e) Any Alteration shall, when completed, be of comparable materials
and finish as then exist in the Demised Premises.

          (f) Any Alteration shall be made promptly and in a good and
workmanlike manner, and, if such Alteration requires the consent of Landlord and
any Mortgagee, it shall be made substantially in accordance with plans and
specifications approved by Landlord and such Mortgagee.  Any Alteration shall be
made in compliance with all applicable permits and authorizations and building
and zoning laws and with all other applicable Laws and requirements of all the
Governmental Authorities, any national or local Board of Fire Underwriters, and
any insurance policy affecting the Demised Premises or any other body hereafter
exercising functions similar to those of any of the foregoing.  Landlord shall,
at the request of Tenant, cooperate at Tenant's sole cost and expense in
connection with any requirement of the Governmental Authorities which requires
Landlord participation in seeking permits and authorizations required for any
Alteration.

          (g) The cost of any such Alterations shall be paid in cash or its
equivalent when due.  If the estimated cost of any Alterations exceeds the
Insurance Threshold Amount, Tenant shall deliver security reasonably
satisfactory to Landlord and Mortgagee for the amount such estimated cost
exceeds the Insurance Threshold Amount.  Without limitation, a payment bond or
letter of credit for such excess amount shall be deemed satisfactory.

          (h) Tenant shall cause workers' compensation insurance including
Employer's Liability insurance in an amount not less than $5,000,000 (part of
which may be provided under Tenant's umbrella policies), covering all
individuals employed in connection with the work and with respect to whom death
or bodily injury claims could be asserted against Landlord, Tenant or the
Demised Premises, and comprehensive general liability insurance on an occurrence
basis for the mutual benefit of Tenant and Landlord, as named insureds, with
limits of not less than $10,000,000 in the event of personal injury or death to
any one individual and to any number of individuals in respect of any one
"occurrence", and with limits of not less than $10,000,000 for property damage,
shall be maintained or caused to be maintained by Tenant at Tenant's sole cost
and expense at all times when any work is in process in connection with any
Alteration.  All such insurance shall be issued by a company or companies of
recognized responsibility, and all policies or certificates therefor issued by
the respective insurers, bearing notations evidencing the payment of premiums or
accompanied by other evidence reasonably satisfactory to Landlord of such
payment, shall be delivered to or as directed by Landlord.

          (i) All fixtures, equipment, improvements and appurtenances attached
to or built into the Demised Premises shall be and shall remain a part of the
Demised Premises and shall be deemed to be the property of Landlord and shall
not be removed by Tenant.

                                      26.
<PAGE>

          (j) Upon completion of any restoration or Alteration for which plans
and specifications are required to be delivered to Landlord and any Mortgagee,
Tenant shall deliver to Landlord three copies of "as-built" plans for such
restoration or Alteration.

SECTION 12.2

     No approval of plans or specifications by Landlord or any Mortgagee or
consent by Landlord or any Mortgagee allowing Tenant to make a restoration or
Alteration to the Demised Premises shall in any way be deemed to be an agreement
by Landlord or such Mortgagee that the contemplated restoration or Alteration
comply with requirements of the Governmental Authorities or any insurance policy
affecting the Demised Premises or any certificates of occupancy for the
Improvements nor shall it be deemed to be a waiver by Landlord of the compliance
by Tenant with any of the terms of this Lease.

                    COMPLIANCE WITH LAW; HAZARDOUS MATERIAL

SECTION 13.1

     Tenant shall, during and after the term of this Lease, at its sole cost and
expense, promptly comply with all Laws, any national or local Board of Fire
Underwriters, any insurer of the Demised Premises or any other body exercising
functions similar to those of any of the foregoing, foreseen or unforeseen,
ordinary as well as extraordinary (including but not limited to Laws related to
Hazardous Materials and clean up of Hazardous Materials and the Americans with
Disabilities Act and local laws), which are now or may hereafter during the term
of this Lease be applicable to the Demised Premises, the use, manner of use or
occupancy thereof or any transaction related thereto, whether or not the same
shall necessitate structural repairs or alterations or interfere with the use or
occupancy of the Demised Premises; however, Tenant shall not be obligated to
correct any building code, Americans with Disabilities Act or Hazardous
Materials violations unless required by, and pursuant to official notice from,
the applicable governmental authority with jurisdiction over the matter.  Tenant
shall not cause by Tenant's actions or negligent inactions or knowingly permit
any Hazardous Material to be brought or deposited or used on the Demised
Premises in a manner which is not in compliance with all Laws.  Hazardous
Material will be used, kept, stored and disposed of in compliance with the
provisions of this Section 13.1.  Tenant shall promptly notify Landlord in
writing of the existence of new types of Hazardous Materials (not previously
disclosed to Landlord) used by Tenant on the Demised Premises.

SECTION 13.2

     Tenant shall not cause or maintain any nuisance in or upon the Demised
Premises, as determined by a court of competent jurisdiction.  Tenant shall not
knowingly suffer or permit the Demised Premises, or any portion thereof, to be
used by the public, as such, in any way as to impair Landlord's title thereto.

                                      27.
<PAGE>

SECTION 13.3

     Tenant may, at its own cost and expense and in its name (or, if required by
the Governmental Authorities, in Landlord's name) contest in any manner
permitted by the Governmental Authorities the validity or enforcement of Laws of
the Governmental Authorities with which Tenant is required to comply pursuant to
this Lease and may defer compliance therewith, provided that:

          (a) such non-compliance shall not subject Landlord to criminal
prosecution or the Demised Premises to lien or sale;

          (b) such non-compliance shall not be in violation of any Underlying
Mortgage; provided that Landlord has given Tenant a copy of such mortgage;

          (c) At the request of Landlord, Tenant shall first deliver to Landlord
a surety bond issued by a surety company of recognized responsibility
satisfactory to Landlord and Mortgagee and in form and substance satisfactory to
Landlord and Mortgagee, or shall provide other security satisfactory to Landlord
protecting Landlord against loss or liability by reason of such non-compliance;
and

          (d) Tenant shall promptly and diligently prosecute such contest.

Landlord, without expense or liability to it, shall cooperate with Tenant in any
such contest.

                              DISCHARGE OF LIENS
                              ------------------

SECTION 14.1

     Tenant will not create or permit to remain, and will discharge, any lien,
encumbrance or charge (levied on account of any Imposition or any mechanic's,
laborer's or materialman's lien or any security interest, conditional sale,
title retention agreement or chattel mortgage, or otherwise) upon the Demised
Premises or any part thereof, having any priority or preference over or ranking
on a parity with the estate, rights and interest of Landlord in the Demised
Premises or any part thereof or the income therefrom, and Tenant will not suffer
any other matter or thing to be done whereby the estate, rights and interest of
Landlord in the Demised Premises or any part thereof might be impaired; provided
that any Imposition may, after the same becomes a lien on the Demised Premises,
be paid or contested in accordance with ARTICLE 6 hereof, and any mechanic's,
laborer's or materialman's lien may be discharged in accordance with Section
14.2 hereof.

SECTION 14.2

     If any mechanic's, laborer's or materialman's lien shall at any time be
filed against the Demised Premises or any part thereof, Tenant, within thirty
(30) days thereafter shall cause the same to be discharged of record by payment,
deposit, bond, order of a court of competent

                                      28.

jurisdiction or otherwise. If Tenant shall fail to cause such lien to be
discharged within the period aforesaid, then, in addition to any other right or
remedy, Landlord may, but shall not be obligated to, discharge the same either
by paying the amount claimed to be due or by procuring the discharge of such
lien by deposit or by bonding proceedings. Any amount so paid by Landlord and
all costs and expenses incurred by Landlord in connection therewith, together
with interest thereon at the Interest Rate from the respective dates of the
making of the payment or incurring of the cost and expense by Landlord shall be
paid by Tenant to Landlord within ten (10) days after demand.

SECTION 14.3

     Nothing in this Lease contained shall be deemed or construed in any way as
constituting the consent or request of Landlord or Tenant, express or implied by
inference or otherwise, to any contractor, subcontractor, laborer or materialman
for the performance of any labor or the furnishing of any materials for any
specific improvement, alteration to or repair of all or part of the Demised
Premises.

                RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS
                -----------------------------------------------

SECTION 15.1

     Landlord shall have the right at any time, after five (5) days' notice
(which notice may be by facsimile) to Tenant (or without notice in case of
emergency or in case any fine, penalty, interest or cost may otherwise be
imposed or incurred on or by Landlord), but no earlier than the expiration of
the applicable cure period hereunder (except in the case of emergency or in case
any fine, penalty, interest or cost may otherwise be imposed or incurred on or
by Landlord), to make any payment or perform any act required of Tenant under
this Lease, and in exercising such right, to incur necessary and reasonable
incidental costs and expenses, including fees and charges of counsel,
accountants, appraisers, architects and engineers.  Nothing herein shall imply
any obligation on the part of Landlord to make any payment or perform any act
required of Tenant, and the exercise of the right so to do shall not constitute
a release of any obligation or a waiver of any Default.

SECTION 15.2

     All payments made by Landlord and all reasonable costs and expenses
incurred by Landlord in connection with any exercise of such right, together
with interest at the Interest Rate from the respective dates of the making of
such payments or the incurring of such costs and expenses, shall be payable to
Landlord by Tenant within ten (10) days after demand.  All sums which may become
payable to Landlord by Tenant pursuant to this ARTICLE 15 shall be deemed
Additional Rent hereunder and Landlord shall have (in addition to any other
right or remedy of Landlord) the same rights and remedies in the event of the
non-payment of any such sums by Tenant as in the cases of default by Tenant in
the payment of Fixed Rent or other Additional Rent.

SECTION 16.1

     Subject to Landlord's compliance with Tenant's and/or any subtenant's
established security measures and requirements provided the same do not prohibit
access to any portion thereof, Tenant shall permit Landlord and any Mortgagee or
prospective Mortgagee and the authorized representatives of Landlord to enter
the Demised Premises without notice in the event of an emergency and upon notice
(which notice may be by facsimile) at all reasonable times during usual business
hours for the purpose of (a) inspecting the same (including, without limitation,
performing tests reasonably required to determine if Tenant is complying with
the provisions of this Lease to be complied with by it including those related
to Hazardous Materials) and (b) making any necessary repairs to the Demised
Premises and performing any work therein that may be necessary by reason of an
Event of Default in making any such repairs or performing any such work.
Nothing herein shall imply any obligation on the part of Landlord to do any such
work which, under any provision of this Lease, Tenant may be required to perform
and the performance thereof by Landlord shall not constitute a waiver of
Tenant's Default in performing the same.  Landlord may, during the progress of
any such work keep and store upon the Demised Premises all necessary materials,
tools, supplies and equipment.  Landlord shall not be liable for reasonable
inconvenience, annoyance, disturbance, loss of business or other damage of
Tenant or any subtenant by reason of making such repairs or the performance of
any such work, or on account of bringing materials, tools, supplies and
equipment into or through the Demised Premises during the course thereof ''''and
the obligations of Tenant under this Lease shall not be affected thereby.
Landlord shall use commercially reasonable efforts to make such repairs in a
manner so as to minimize interference with the normal conduct of business of
Tenant and other occupants of the Demised Premises, provided that Landlord shall
not be required to employ overtime or premium labor therefor.

SECTION 16.2

     Subject to Landlord's compliance with Tenant's and/or any subtenant's
established security measures and requirements provided the same do not prohibit
access to any portion thereof, Landlord shall have the right at all reasonable
times to enter upon the Demised Premises for the purpose of exhibiting the same
to prospective mortgagees, purchasers and, during the last twenty-four (24)
months of the term of this Lease, to prospective tenants.

unreasonably withheld, conditioned or delayed, neither this Lease nor any
interest of Tenant in this Lease or in any sublease or in any subrents shall be
sold, assigned, transferred, mortgaged, pledged, hypothecated, or otherwise
disposed of or encumbered, whether voluntarily, by operation of law or
otherwise, nor shall Tenant sublet all or any part of the Demised Premises or
agree to do any of the foregoing.  Landlord shall provide such consent or denial
of consent within ten (10) business days after Tenant's request therefor.  Any
such denial shall include a reasonable explanation of the basis for denial.  No
such sale, assignment, transfer, mortgage, pledge or hypothecation shall release
Tenant from liability hereunder, unless otherwise agreed in writing by Landlord
and Mortgagee.

     Any assignment or other attempted disposition or encumbering of this Lease
or any sublease hereof, or of the interest of Tenant hereunder, without the
prior written consent of Landlord or without full compliance with any and all
reasonable requirements set forth in such consent of Landlord or in this Lease,
in addition to constituting an Event of Default under this Lease, shall be
invalid and of no effect against Landlord.

SECTION 17.2

     The provisions of Section 17.1 shall apply to transfers of capital stock
and any other mechanism which results in a change of control of Tenant (if
Tenant is a corporation) and to transfers of an interest in the distributions of
profits and losses and any other mechanism which results in a change of control
of Tenant (if Tenant is a partnership or joint venture or other entity) as if
such transfer or other mechanism were an assignment of this lease, except that
the provisions of Section 17.1 shall not apply to (w) the public sale of
securities of Tenant, (x) transactions with a corporation or other entity into
or with which Tenant is merged or consolidated, (y) transactions with a
corporation or other entity to which substantially all of Tenant's assets are
transferred or (z) transfers to any corporation or other entity which controls
or is controlled by Tenant or is under common control with Tenant (prior to or
after the transaction involved), provided, that (i) in any of such events within
                                 --------  ----
ten (10) days after the effective date of any such transaction, the executed
instrument of assignment and assumption, if applicable, in the form previously
exhibited to Landlord, in which such assignee assumes all of the terms,
covenants and conditions of this Lease on Tenant's part to be performed and
observed shall have been delivered to Landlord and (ii) in the event of a
transaction described in subsections (x) or (y), above, the successor to Tenant
has a rating equal to or better than CCC+ (Standard and Poors) or the equivalent
from another recognized rating agency.  Tenant shall, however, notify Landlord
of such assignment not less than ten (10) days prior to the effective date
thereof and shall promptly deliver to Landlord such other documentation and
evidence with respect thereto as Landlord may reasonably request.  For purposes
of this Section 17.2, the term "control" means,

indirectly, of at least fifty-one (51%) percent of all its voting stock, and in
case of a partnership, joint venture or other entity, ownership, directly or
indirectly, of at least fifty-one (51%) percent of all the general partnership
or other interests therein.

SECTION 17.3

     Any consent by Landlord to a sale, assignment, transfer, mortgage, pledge,
hypothecation, or other disposition or encumbering of this Lease or of any
sublease, shall apply only to the specific transaction thereby authorized and
shall not relieve Tenant from the requirement of obtaining the prior written
consent of Landlord to any further sale, assignment, transfer, mortgage, pledge,
hypothecation, or other disposition or encumbering of this Lease or of any
sublease.  Contemporaneously with the request of Tenant for each such consent,
Tenant shall submit, in writing, information sufficient to enable Landlord to
decide with respect thereto.

SECTION 17.4

     If this Lease be assigned, Landlord may, and is hereby empowered to collect
rent from the assignee.  If the Demised Premises or any part thereof be underlet
or occupied by any Person other than Tenant, Landlord, upon the occurrence of
and Event of Default, may, and is hereby empowered to, collect rent from the
undertenant or occupant.  In either of such events, Landlord shall apply the
rent received by it to the Fixed Rent and the Additional Rent, and such
collection shall not be deemed a waiver of the covenant of Tenant against
mortgaging or pledging this Lease, or the acceptance of such assignee,
undertenant or occupant as Tenant under this Lease or a release of Tenant from
performance of Tenant's covenants hereunder.

SECTION 17.5

     Notwithstanding the foregoing provisions of this ARTICLE 17, Landlord shall
not unreasonably withhold, condition or delay its consent to any subleases,
licenses or concessions to be entered into by Tenant with respect to all or any
portion of the Demised Premises.  During the term of this Lease, Tenant shall be
entitled to all rent, income and profits relating to any subleases, licenses or
concessions at the Demised Premises (collectively, the "Sublease Profits"),
provided, however, that Tenant hereby grants to Landlord a first priority
- --------  -------
security interest in and to such Sublease Profits which shall entitle Landlord
to exercise the right to receive the Sublease Profits while an Event of Default
in payment of Fixed Rent and/or Additional Rent exists hereunder.  Landlord
shall apply all Sublease Profits toward payment of delinquent and current Fixed
Rent and Additional Rent (as applicable), in that order.  Any excess shall be
promptly paid to Tenant.

SECTION 17.6

     Any violation of any provision of this Lease, whether by act or omission,
by any assignee, subtenant or undertenant, shall be deemed a violation of such
provision by Tenant, it being the intention and meaning of the parties hereto
that Tenant shall assume and be liable to Landlord for

                                      32.

any and all acts and omissions of any and all assignees, subtenants and

     Landlord hereby approves the SGI Lease as an acceptable sublease, provided
that the SGI Lease shall be subject and subordinate to this Lease upon the
execution and delivery by SGI of a subordination, nondisturbance and attornment
agreement in the form attached hereto as Exhibit C.  Tenant shall promptly

notify Landlord of any material defaults under the SGI Lease or any other

received or delivered by Tenant.    Notwithstanding any other provision of this
Lease, Landlord hereby acknowledges that any provisions of or rights granted
under the SGI Lease that may conflict or are inconsistent with the terms and
conditions of this Lease shall not be deemed a violation of this Lease.

encumbrance or by Law, or shall be subject to withholding or diminution at the
source, by reason of any taxes (including a tax on rent), assessments, expenses,
indebtedness, obligation or liabilities of any character, foreseen or unforeseen
and the same is required to be paid by Tenant under this Lease, and whether or
not valid, or (b) by reason of any claims, demands, charges or liens of any
nature, foreseen or unforeseen, incurred by any Person, and the same is required
to be paid by Tenant under this Lease, so that the Fixed Rent or any part
thereof would be unavailable to Landlord, when due, or (c) the payment in full
of the Fixed Rent when due and payable under this Lease shall be delayed,
hindered or prevented, or the right of Landlord to use or apply the same shall
be adversely affected due to the fault of Tenant, or (d) the Demised Premises
shall be or become subject to or burdened by any lien, charge or encumbrance (i)
of any kind other than permitted in this Lease or otherwise approved by Landlord

expenses, indebtedness, obligations and liabilities, and to eliminate or nullify
the cause of such attachment, claim, demand, charge, lien, levy, order, process,
encumbrance, withholding or diminution, (ii) eliminate or prevent any such
delay, hindrance or obstacle in the payment in full of the Fixed Rent when the
same is due and payable under this Lease, and (iii) protect fully the right of
Landlord to use or apply the Fixed Rent for its purposes.  Except as otherwise
set forth in this Lease, it is the intention of the Tenant in giving the
undertakings set forth in this ARTICLE 18 that the Fixed Rent, the Additional
Rent and other sums payable under this Lease shall be received and enjoyed by
the Landlord, or its assignee, as an absolutely net sum, so that said rent shall
be available for use by the Landlord, or its assignee, when due, without
diminution to any extent and without delay or postponement for any reason.

SECTION 19.1

     Tenant represents and agrees that the Demised Premises, the title thereto,
and the present uses and non-uses thereof, have been examined by Tenant and that
Tenant accepts the same in the condition or state in which they or any of them
now are, without representation or warranty, express or implied in fact or by
law, by Landlord and without recourse to Landlord, as to the title thereto, the
nature, condition or usability thereof or the use or uses to which the Demised
Premises or any part thereof may be put.  Tenant further represents that Tenant
was the previous owner of fee title to the Demised Premises and sold the Demised
Premises to Landlord pursuant to the Original Purchase Agreement (as defined
herein).

SECTION 19.2

     Tenant, upon paying the Fixed Rent and the other Additional Rent in this
Lease provided for and observing and keeping the covenants, agreements, terms
and conditions of this Lease on its part to be performed, shall, subject to its
terms, lawfully and quietly hold, occupy and enjoy the Demised Premises during
the term of this Lease, without hindrance or molestation by Landlord or by any
other Person claiming under Landlord subject, however, to the exceptions and
reservations of this Lease.  Any breach or default of this ARTICLE 19, shall not
give to Tenant any right during the term of this Lease to cancel or terminate
this Lease or to abate or make deduction from or offset against Fixed Rent,
Additional Rent or any other sums payable by Tenant under this Lease, or to fail
to perform any other covenant, agreement or obligation of Tenant hereunder, but
nothing herein shall preclude Tenant from obtaining damages and injunctive
relief against Landlord or any Person claiming under Landlord.  The covenant in
this Section 19.2 shall be construed as a covenant running with the Demised
Premises and not as a personal covenant or obligation of Landlord, except to the
extent of Landlord's  covenants, agreements, obligations and liabilities that
arise while Landlord possesses an interest in this Lease and/or the Demised
Premises, and provided that any successors or assigns of Landlord assume all of
Landlord's covenants, agreements, obligations and liabilities hereunder.

or contractors;

          (b) any act, omission or negligence of Tenant or any agent,
contractor, employee, licensee or invitee of Tenant;

          (c) any accident or injury to any individual (including death) or
damage to property occurring in, on or about the Demised Premises or any part

or their respective employees, agents or contractors; and

          (d) any failure on the part of Tenant to perform or comply with any of
the agreements, terms or conditions contained in this Lease on its part to be
performed or complied with.

     Landlord shall promptly notify Tenant of any claim asserted against
Landlord for which Landlord claims Tenant may have to indemnify Landlord
hereunder.  In the event that any action or proceeding shall be brought against
Landlord or any Mortgagee by reason of any matter covered by this Section 20.1,
Tenant, upon written notice from Landlord or any Mortgagee will, at Tenant's
sole cost and expense, resist or defend the same.

and charges, including counsel fees and charges, lawfully incurred in obtaining
possession of the Demised Premises after an Event of Default or after Tenant's

     If any excavation or other building operation shall be about to be made or

respective representatives to enter the Demised Premises and to shore the

the safety or preservation of the Demised Premises all at such owner or lessee's
sole cost and expense.  Landlord shall not be liable for any inconvenience,
annoyance, disturbance, loss of business or other damage arising therefrom and
Tenant's obligations hereunder shall not thereby be affected.  Nothing in this

SECTION 22.1

     If, during the term of this Lease, any one or more of the following acts or
occurrences (any one of such occurrences or acts being hereinafter called an
"Event of Default") shall happen:

          (a) Tenant shall fail to make payment of any installment of the Fixed
Rent more than five (5) days after the same shall have become due; or

          (b) Tenant shall fail to make payment of any Additional Rent after the
same shall have become due for more than ten (10) days after written notice
thereof from Landlord to Tenant;

          (c) Tenant shall fail to perform or comply with any of the other
covenants, agreements, terms and conditions of this Lease to be performed or
complied with by Tenant, and such default shall continue for a period of thirty
(30) days after written notice thereof from Landlord to Tenant, or, in the case
of a default which by its nature cannot with due diligence be cured within
thirty (30) days (and the continuance of which for the period required for cure
will not (i) subject Landlord or any Mortgagee to prosecution for a crime, (ii)
subject all or part of the Demised Premises to being condemned or (iii) result
in the termination of any Underlying Mortgage, provided that Landlord has given
Tenant a copy of such mortgage), Tenant shall not (x) proceed promptly upon the
giving of such notice and with all due diligence to prosecute to completion all
steps to remedy the same and (y) complete such remedy within a reasonable time
after the giving of such notice by Landlord; or

          (d) Tenant shall file a voluntary petition under any bankruptcy or
insolvency law or shall be adjudicated a bankrupt or insolvent, or shall file
any petition or answer seeking any reorganization, composition, readjustment or
similar relief under any present or future

                                      36.

bankruptcy or other applicable law, or shall seek or consent to or acquiesce in
the appointment of any trustee, receiver, or liquidator of Tenant or of all or
any substantial part of its properties or of all or any substantial part of the
Demised Premises; or

          (e) If within sixty (60) days after the filing of an involuntary
petition in bankruptcy against Tenant or the commencement of any proceeding
against Tenant seeking any reorganization, composition, readjustment or similar
relief under any Law, such proceeding shall not have been dismissed, or if,
within sixty (60) days after the appointment, without the consent or
acquiescence of Tenant, of any trustee, receiver or liquidator of Tenant or of
all or any substantial part of the properties of Tenant or all or any
substantial part of the Demised Premises, such appointment shall not have been
vacated or stayed on appeal or otherwise, or if, within sixty (60) days after
the expiration of any such stay, such appointment shall not have been vacated,
or if within sixty (60) days after the taking of possession, without the consent
or acquiescence of Tenant, of the property of Tenant by any Governmental
Authority pursuant to statutory authority for the dissolution or liquidation of
Tenant, such taking shall not have been vacated or stayed on appeal or
otherwise; or

          (f) if the Demised Premises shall be abandoned by Tenant, unless the
same is being sublet by Tenant to other Persons pursuant to and in accordance
with the terms of this Lease;

          (g) if any event shall occur or any contingency shall arise whereby
this Lease and the estate hereby granted or the unexpired balance of the Term
would, by operation of law or otherwise, devolve upon or pass to any party other
than Tenant, except as is expressly permitted under ARTICLE 17; or

          (h) Tenant shall be in default under the SGI Lease or any other lease
relating to more than 50,000 square feet of space at the Demised Premises (a
"Major Sublease");

then, and in such event, Landlord may at its option, then or thereafter while
any such Event of Default shall continue and notwithstanding the fact that
Landlord may have any other remedy hereunder or at law or in equity, by written
notice to Tenant, designate a date, not less than sixty (60) days after the
giving of such notice, on which this Lease shall terminate; and thereupon, on
such date the term of this Lease and the estate hereby granted shall expire and
terminate upon the date specified in such notice with the same force and effect
as if the date specified in such notice were the date herein fixed for the
expiration of the term of this Lease, and all rights of Tenant hereunder shall
expire and terminate, but Tenant shall remain liable as hereinafter provided.

     Nothing in the preceding paragraph shall be deemed to require Landlord to
give the five (5) day notice provided for therein prior to the commencement of a
summary proceeding for non-payment of rent or a plenary action for recovery of
rent, it being intended that such notice is for the purpose of creating a
conditional limitation hereunder pursuant to which this Lease shall terminate
and Tenant, if it remains in occupancy, shall become a holdover tenant.

                                      37.
<PAGE>

SECTION 22.2

     Tenant's due and punctual performance of all of its obligations under this
Lease throughout the Term is of importance to Landlord.  Without limiting the
provisions of Section 22.1, if Tenant shall default in the timely payment of any
installment of Fixed Rent, and any such default shall continue or be repeated
for two consecutive months or for a total of three months in any period of
twelve months then, notwithstanding that such Defaults shall have each been
cured within the applicable period, if any, as above provided, any further
                                                     --------
similar Default shall be deemed to be deliberate and Landlord thereafter may
serve the said five (5) days' notice of termination upon Tenant without
affording to Tenant an opportunity to cure such further Default.

SECTION 22.3

          (a) If a petition is filed by, or an order-for relief is entered
against Tenant under Chapter 7 of the Bankruptcy Code and the trustee of Tenant
elects to assume this Lease for the purpose of assigning it, such election or
assignment, or both, may be made only if all of the terms and conditions of
subparagraphs (b) and (d) below are satisfied. To be effective, an election to
assume this Lease must be in writing and addressed to Landlord, and in
Landlord's business judgment, all of the conditions hereinafter stated, which
Landlord and Tenant acknowledge to be commercially reasonable, must have been
satisfied. If the trustee fails so to elect to assume this Lease within sixty
(60) days after his appointment, this Lease will be deemed to have been
rejected, and Landlord shall then immediately be entitled to possession of the
Demised Premises without further obligation to Tenant or the trustee and this
Lease shall be terminated. Landlord's right to be compensated for damages in the
bankruptcy proceeding, however, shall survive such termination.

          (b) If Tenant files a petition for reorganization under Chapters 11 or
13 of the Bankruptcy Code, or if a proceeding fried by or against Tenant under
any other chapter of the Bankruptcy Code is converted to a Chapter 11 or 13
proceeding and Tenant's trustee or Tenant as debtor-in-possession fails to
assume this Lease within sixty (60) days from the date of the filing of such
petition or conversion, then the trustee or the debtor-in-possession shall be
deemed to have rejected this Lease. To be effective any election to assume this
Lease must be in writing addressed to Landlord and, in Landlord's business
judgment, all of the following conditions, which Landlord and Tenant acknowledge
to be commercially reasonable, must have been satisfied:

              (i) The trustee or the debtor-in-possession has cured or has
     provided to Landlord adequate assurance, as defined in this subparagraph
     (b), that:

                  (A) The trustee will cure all monetary defaults under this
                      Lease within ten (10) days from the date of assumption

                  (B) The trustee will cure all nonmonetary defaults under this
                      Lease within thirty (30) days from the date of assumption.

                                      38.
<PAGE>

               (i)    The trustee or the debtor-in-possession has compensated
     Landlord, or has provided Landlord with adequate assurance, as hereinafter
     defined, that within ten (10) days from the date of assumption Landlord
     will be compensated for any pecuniary loss it has incurred arising from the
     default of Tenant, the trustee, or the debtor-in-possession, as recited in
     Landlord's written statement of pecuniary loss sent to the trustee or
     debtor-in-possession.

               (ii)   The trustee or the debtor-in-possession has provided
     Landlord with adequate assurance of the future performance of each of
     Tenant's obligations under this Lease; provided, however, that:

                      (A) From and after the date of assumption of this Lease,
                          the trustee or the debtor-in-possession shall pay the
                          Fixed Rent and Additional Rent payable under this
                          Lease in advance in equal monthly installments on each
                          date that such Rent are payable.

                      (B) The trustee or debtor-in-possession shall also deposit
                          with Landlord, as security for the timely payment of
                          any and all sums due under this Lease, an amount equal
                          to three (3) months' Fixed Rent and other monetary
                          charges accruing under this Lease;

                      (C) If not otherwise requested by the terms of this Lease,
                          the trustee or the debtor-in-possession shall also pay
                          in advance, on each day that any installment of Fixed
                          Rent is payable, one-twelfth (1/12) of Tenant's annual
                          Impositions, operating expenses, and other obligations
                          under this Lease; and

                      (D) The obligations imposed upon the trustee or the
                          debtor-in-possession will continue for Tenant after
                          the completion of bankruptcy proceedings.

               (iii)  Landlord has determined that the assumption of this Lease
     will not:

                      (A) Breach any provision in any other lease, mortgage,
                          financing agreement, or other agreement by which
                          Landlord is bound relating to the Demised Premises; or

                      (B) Disrupt, in Landlord's judgment, the occupant mix or
                          occupant consistency of the Demised Premises or any
                          other attempt by Landlord to provide or exclude a
                          specific variety of occupants in the Demised Premises
                          which, in Landlord's judgment, would be most
                          beneficial to all of the tenants thereof (including
                          Landlord) and would enhance the security, image,
                          reputation, and profitability thereof.

               (iv)   For purposes of this subparagraph (b), "adequate
     assurance" means that:

                                      39.
<PAGE>

                      (A) Landlord determines that the trustee or the debtor-in-
                          possession has, and will continue to have, sufficient
                          unencumbered assets, after the payment of all secured
                          obligations and administrative expenses, to assure
                          Landlord that the trustee or the debtor-in-possession
                          will have sufficient funds timely to fulfill Tenant's
                          obligations under this Lease and to keep the Demised
                          Premises properly staffed with sufficient employees to
                          conduct a fully operational, actively promoted
                          business in the Demised Premises; and

                      (B) An order shall have been entered segregating
                          sufficient cash payable to Landlord and/or a valid and
                          perfected first lien and security interest shall have
                          been granted in property of Tenant, trustee, or
                          debtor-in-possession which is acceptable in value and
                          kind to Landlord, to secure to Landlord the obligation
                          of the trustee or debtor-in-possession to cure all
                          monetary and nonmonetary defaults under this Lease
                          within the time periods set forth above.

          (c) In the event this Lease is assumed by a trustee appointed for
Tenant or by Tenant as debtor-in-possession under the provisions of subparagraph
(b) above and, thereafter, Tenant is either adjudicated bankrupt or files a
subsequent petition for arrangement under Chapter 11 of the Bankruptcy Code,
then Landlord may, at its option, terminate this Lease and all the Tenant's
rights under it, by giving written notice of Landlord's election so to
terminate.

          (d) If the trustee or the debtor-in-possession has assumed this Lease,
pursuant to subparagraph (a) or (b) above, to assign or to elect to assign
Tenant's interest under this Lease or the estate created by that interest to any
other person, such interest or estate may be assigned only if the intended
assignee has provided adequate assurance of future performance, as defined in
this subparagraph (d), of all of the terms, covenants, and conditions of this
Lease.  For purposes of this subparagraph (d), "adequate assurance of future
performance" means that Landlord has ascertained that each of the following
conditions has been satisfied:

              (ii)    The assignee has submitted a current financial statement,
     audited by a certified public accountant, which shows a net worth and
     working capital in amounts determined by Landlord to be sufficient to
     assure the future performance by the assignee of the tenant's obligations
     under this Lease;

              (iii)   If requested by Landlord, the assignee will obtain
     guarantees, in form and substance satisfactory to Landlord (i.e. letter(s)
     of credit), from one or more persons who satisfy Landlord's standards of
     creditworthiness; and

              (iv)    Landlord has obtained consents or waivers from any third
     parties which may be required under any lease, mortgage, financing
     arrangement, or other agreement by which Landlord is bound, to enable
     Landlord to permit such assignment.

                                      40.
<PAGE>

          (e) When, pursuant to the Bankruptcy Code, the trustee or the debtor-
in-possession is obligated to pay reasonable use and occupancy charges for the
use of all or part of the Demised Premises, it is agreed that such charges will
not be less than the Fixed Rent as defined in this Lease, plus Additional rent
and other monetary obligations of Tenant included herein.

          (f) Neither Tenant's interest in this Lease nor any estate of Tenant
created in this Lease shall pass to any trustee, receiver, assignee for the
benefit of creditors, or any other person or entity, nor otherwise by operation
of law under the laws of any state having jurisdiction of the person or property
of Tenant, unless Landlord consents in writing to such transfer.  Landlord's
acceptance of Fixed Rent, Additional Rent  or any other payments from any
trustee, receiver, assignee, person, or other entity will not be deemed to have
waived, or waive, either the requirement of Landlord's consent or Landlord's
right to terminate this Lease for any transfer of Tenant's interest under this
Lease without such consent.

SECTION 22.4

     If this Lease is terminated as provided in Section 22.1 or 22.2, or as
permitted by law, Tenant shall peaceably quit and surrender possession of the
Demised Premises to Landlord, and Landlord may, without further notice enter
upon, re-enter, possess and repossess the same by summary proceedings, ejectment
or other judicial proceeding, and again have, repossess and enjoy the same

SECTION 22.5

          (a) If Landlord re-enters and obtains possession of the Demised
Premises, as provided in Section 22.4 of this Lease, Landlord shall have the
right, without notice, to repair or alter the Demised Premises in such manner as
Landlord may reasonably deem necessary or advisable so as to put the Demised
Premises in good order, including restoration of the Demised Premises caused by
any removal of machinery and equipment by Tenant, and shall have the right, at
Landlord's option, to re-let the Demised Premises or a part thereof at such
rentals and on such conditions, including concessions and free rent periods, as
Landlord in good faith, in its reasonable discretion, may determine, and Tenant
shall pay to Landlord on demand all reasonable expenses incurred by Landlord in
obtaining possession, and in altering, repairing and putting the Demised
Premises in good order and condition and in reletting the same, including fees
and charges of attorneys, engineers and architects and brokers, and all other
expenses or commissions.

          (b) Tenant shall pay to Landlord upon the Fixed Rent payment dates
following the date of such re-entry to and including the date set forth in
ARTICLE 4 hereof for the expiration of the Term of this Lease, the sums of money
which would have been payable by Tenant as Fixed Rent hereunder on such Fixed
Rent payment dates as if Landlord had not re-entered and resumed possession of
the Demised Premises, deducting only the net amount of rent, if any, which
Landlord shall actually receive (after deducting therefrom the expenses, costs
and payments of Landlord which, in accordance with the terms of this Lease would
have been borne by Tenant) in the meantime from and by any reletting of the
Demised Premises, and Tenant shall remain liable for all sums otherwise payable
by Tenant under this Lease, including but not limited to

                                      41.
<PAGE>

Additional Rent, such expenses of Landlord, as well as for any deficiency
aforesaid, and Landlord shall have the right from time to time to begin and
maintain successive actions or other legal proceedings against Tenant for the
recovery of such deficiency, expenses or damages and for a sum equal to any
installments of Fixed Rent and Additional Rent. As an alternative remedy, in the
event of termination of this Lease, Landlord shall be entitled to damages
against Tenant for breach of this Lease, at any time (whether or not Landlord
shall have become entitled to or shall have received any damages as hereinabove
provided) in an amount equal to the excess, if any, of (x) the Fixed Rent and
Additional Rent which would be payable under this Lease for the period
commencing on the date of the expiration of this Lease to the end of the term of
this Lease had not so terminated, over (y) the fair rental value (including
Additional Rent) of the Demised Premises for the same period, discounted to the
date of payment at the rate of six percent (6%) per annum. The obligation and
liability of Tenant to pay the Fixed Rent and Additional Rent shall survive the
commencement, prosecution and termination of any action to secure possession of
the Demised Premises. Nothing contained herein shall be deemed to require
Landlord to wait to begin such action or other legal proceedings until the date
when this Lease would have expired had there not been any Event of Default.
Landlord shall use reasonable efforts to relet the Demised Premises, but shall
not be liable for its reasonable failure to relet all or part of the Demised
Premises and shall not, under any circumstances, have any liability for its
reasonable failure to sublet a part of the Demised Premises, particularly when
the possible letting of the whole of the Demised Premises will be adversely
affected thereby.

          (c) Nothing herein contained shall limit or prejudice the right of
Landlord, in any bankruptcy or reorganization or insolvency proceeding, to prove
for and obtain as liquidated damages by reason of such termination an amount
equal to the maximum allowed by any bankruptcy or reorganization or insolvency
proceedings, or to prove for and obtain as liquidated damages by reason of such
termination, an amount equal to the maximum allowed by any statute or rule of
law whether such amount shall be greater or less than the damages provided
hereinafter.

     At any time after an Event of Default shall have occurred and while it is
continuing, Landlord shall be entitled to enjoin any breach by Tenant of any of

any period the payment thereof by Tenant to Landlord may be overdue by more than
five (5) days.  In addition, Tenant's failure to pay any Fixed Rent or
Additional Rent within five (5) days of the due date thereof shall result in the

     In any action or proceeding (other than an arbitration proceeding under
ARTICLE 10 or ARTICLE 11) which Landlord or Tenant may prosecute to enforce its
rights hereunder, the non-prevailing party shall pay all reasonable costs
incurred by the other party therein, including attorneys' fees and charges
(including those on appeal) and such costs and attorneys' fees and charges shall
be made a part of any judgment in such action.  If Landlord shall, without fault
on its part, be made a party to any litigation commenced against Tenant, and if
Tenant shall not provide Landlord with counsel satisfactory to Landlord (of
which fact Landlord shall promptly notify Tenant), Tenant shall pay all
reasonable costs and attorneys' fees and charges (including those on appeal)
reasonably incurred or paid by Landlord in connection with such litigation.

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

SECTION 24.1

     The Lease shall be subject and subordinate at all times to any Underlying
Mortgage and to any Underlying Lease, and to all renewals, modification,
amendments, consolidations, replacements and extensions thereof, provided that
Tenant receives from the holder of such Underlying Mortgage or Underlying Lease,
an agreement that (a) the Tenant's possession, use and enjoyment of the Demised
Premises under this Lease shall not be disturbed and (b) all of Tenant's rights
and privileges under this Lease (including, but not limited to its Purchase
Option rights) shall be upheld and honored so long as there is no Event of
Default hereunder.  The foregoing is self-operative and no further confirmation
thereof is required.  Until Tenant receives such an agreement, this Lease shall
not be so subject and subordinate.  If, by dispossess, foreclosure or otherwise,
such Mortgagee or Superior Lessor, or any successor in interest, shall come into
possession of the Demised Premises, or shall become the owner of the Demised
Premises, or take over the rights of Landlord in the Demised Premises, it will
not disturb the possession, use or enjoyment of the Demised Premises by Tenant,
its successors or assigns, nor disaffirm this Lease or Tenant's rights or estate
hereunder, so long as all of the obligations of Tenant are fully performed in
accordance with the terms of this Lease.  Tenant shall execute and deliver any
instrument which may be required by Landlord or any Mortgagee or Superior Lessor
in confirmation of such subordination promptly upon the request of Landlord, any
Mortgagee or

                                      43.
<PAGE>

any Superior Lessor. Such agreement shall contain such other provisions as the
holder of any Underlying Mortgage may reasonably require, so long as such other
provisions do not (i) modify this Lease or (ii) impose any additional costs,
obligations or liabilities on Tenant except to a de minimis extent.

SECTION 24.2

     If any Mortgagee, Superior Lessor or any designee of any Mortgagee or any
Superior Lessor ("Successor Landlord"), shall succeed to the rights of Landlord
under this lease, whether through possession or foreclosure action or delivery
of a new lease or deed, then at the request of such Successor Landlord and upon
such Successor Landlord's written agreement to accept Tenant's attornment,
Tenant shall attorn to and recognize such Successor Landlord as the landlord
under this Lease and shall promptly execute and deliver any instrument that such
Successor Landlord may reasonably request to evidence such attornment; provided
that such instrument includes non-disturbance provisions reasonably satisfactory
to Tenant.  Such Successor Landlord shall not be (a) liable for any previous act
or omission of Landlord; (b) subject to any credits, offsets, claims, counter-
claims, demands or defenses which Tenant may have had against Landlord prior to
Successor Landlord taking title or delivery of possession of the Demised
Premises; or (c) bound by any payments of rent which Tenant might have made for
more than one (1) month in advance to Landlord.

SECTION 24.3

     Tenant shall give notice to any Mortgagee or any Superior Lessor of any act
or omission of Landlord which Tenant believes would give it the right to
terminate this Lease or abate rent hereunder, if said Mortgagee or Superior
Landlord has delivered a written request to Tenant to that effect, including
said Mortgagee's or Superior Landlord's notice address.

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

SECTION 25.1

     On the last day of the term hereof, or upon any earlier termination of this
Lease, or upon any re-entry by Landlord upon the Demised Premises, Tenant shall
surrender the Demised Premises unto the possession and use of Landlord without
delay and in good order, condition and repair, reasonable wear and tear
excepted, free and clear of all lettings and occupancies and free and clear of
all liens and encumbrances other than those created or consented to by Landlord.
Landlord hereby consents to (i) all liens and encumbrances of record affecting
the Demised Premises as of the date of this Lease, and (ii) all matters
disclosed by the survey of the Demised Premises dated 8/27/99 prepared by BRW.
All machinery, equipment and fixed assets (except for Tenant's trade fixtures
and business equipment) now or hereafter installed at the Demised Premises and
used in the operations thereof shall be and remain part of the Demised Premises.

SECTION 25.2

     Tenant may remove Tenant's personal property from the Demised Premises
during the term of this Lease and Tenant shall repair any damage to the Demised
Premises caused by such removal.  At Landlord's election, Tenant shall remove
Tenant's personal property from the Demised Premises no later than the last day
of the Term.  Any personal property of Tenant which shall remain in the
Improvements after the termination of this Lease may, at the option of Landlord,
be deemed to have been abandoned by Tenant and either may be retained by
Landlord as its property or be disposed of without accountability in such manner
as Landlord may see fit or Landlord may require Tenant to remove the same at
Tenant's expense.

SECTION 25.3

     Landlord shall not be responsible for any loss or damage occurring to any
property owned by Tenant or any subtenant unless such loss or damage is caused
by Landlord's, or its employee's, agent's or contractor's negligent act or
omission or willful misconduct.

SECTION 25.4

     Any subrents shall be apportioned between Landlord and Tenant as of the
last day of the term hereof or as of the effective date of any earlier
termination of this Lease, provided that if Tenant shall then be in default in
the performance of any Tenant's covenants, agreements and undertakings in this
Lease, then to the extent of the amount of any such default, Tenant shall not be
entitled to receive an apportionment.

SECTION 25.5

     In the event of a termination of this Lease in accordance with its terms
and a holding over by Tenant thereafter, there shall be no renewal or extension
of this Lease by operation of law, but Tenant shall continue to pay to Landlord
for each month of use and occupancy a sum equal to two times the Fixed Rent
installment then payable, and also pay all other amounts payable by Tenant to
Landlord hereunder, the Fixed Rent to be calculated on a per diem basis for each
day or fraction thereof that Tenant remains in occupancy of the Demised Premises
after expiration of the term of this Lease.

SECTION 25.6

     The provisions of this ARTICLE 25 shall survive any termination of this
Lease.

setting forth such modifications) and the dates to which the Fixed Rent and the
other Additional Rent have been paid, and either stating that to the knowledge
of Tenant or Landlord, as the case may be, no default exists in the performance
of any covenant, agreement or condition contained in this Lease or specifying
each default of which Tenant or Landlord, as the case may be, may have
knowledge. Any such statement delivered pursuant to this ARTICLE 27 may be

may enforce any and all of the terms of this Lease, to the extent so assigned,

                    LIMITATION OF THE LANDLORD'S LIABILITY
                    --------------------------------------

SECTION 29.1

     Provided that Landlord complies with Section 29.1, Landlord shall have no
personal liability hereunder and Tenant shall look solely to Landlord's estate
and interest in the Demised Premises, the Security Deposit, and/or Landlord's
operating account(s) in connection with the Demised Premises and/or this Lease
for the satisfaction of any right or remedy of Tenant for the collection of a
judgment (or other judicial process) requiring payment of money by Landlord, and
no other property of Landlord or the partners or members thereof, if Landlord is
not an individual or corporation, shall be subject to levy, attachment or other
enforcement procedures for satisfaction of Tenant's remedies under this Lease.
Landlord covenants that it shall at all times during the term of this Lease
maintain at least $5,000,000.00 of equity in the Demised Premises, where
"equity" means (i) the fair market value of the Demised Premises minus (ii) the
total amount of all mortgages, liens and other monetary encumbrances, if any,
against the Demised Premises. Tenant agrees that Landlord's failure to pay any
judgment or award to Tenant shall not affect Tenant's obligations under this
Lease.

     The term "Landlord" as used in this Lease, so far as covenants or
agreements on the part of Landlord are concerned, shall be limited to the owner
or owners of Landlord's interest in this Lease at the time in question, and in
the event of any transfer or transfers of all of such interest, except a
transfer by way of security, Landlord herein named (and in case of any
subsequent transfer, the then transferor) shall be automatically freed and
relieved from and after the date of such transfer of all liability as respects
the performance of any covenants or agreements on the part of Landlord contained
in this Lease thereafter to be performed but shall remain liable for such
obligations accruing prior to such transfer; provided, however, that
                                             --------  -------

          (a) any funds in the hands of such Landlord or the then transferor at
the time of such transfer, in which Tenant has an interest, shall be turned over
to the transferee and any amount then due and payable to Tenant by Landlord or
the then transferor under any provision of this Lease, shall be paid to Tenant
simultaneous with such transfer; and

          (b) upon any such transfer, the transferee shall be deemed to have
assumed, subject to the limitations of this ARTICLE 29, all of the covenants,
agreements and conditions in this Lease to be performed on the part of Landlord,
it being intended hereby that the covenants and agreements contained in this
Lease on the part of Landlord shall, subject as aforesaid, be binding on
Landlord, its successors and assigns, only during and in respect of their
respective successive periods of ownership; however, no such transfer shall
release any transferor from its obligations hereunder accruing during its
respective period of ownership.

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

     The specific remedies to which Landlord may resort under the terms of this
Lease are cumulative and are not intended to be exclusive of any other remedies
or means of redress to which Landlord may be lawfully entitled in case of any
breach by Tenant of any provision of this Lease.  The failure of Landlord to
insist in any one or more cases upon the strict performance of any of the
covenants of this Lease, or to exercise any option herein contained, shall not
be construed as a waiver or relinquishment for the future of such covenants or
option.  A receipt by Landlord of Fixed Rent or Additional Rent with knowledge
of the breach of any covenant hereof shall not be deemed a waiver of such
breach.

SECTION 32.1

     Tenant shall not record this Lease.  Landlord and Tenant shall execute and
deliver in recordable form a memorandum of lease for the purpose of recording
and giving notice of this Lease.  If this Lease terminates, Tenant shall, upon
the request of Landlord, sign an agreement in recordable form reflecting
termination of this Lease and if Tenant shall fail to do so within ten (10)
business days of Landlord's request therefor, Tenant hereby appoints Landlord as
Tenant's attorney in fact to sign such an agreement on behalf of Tenant.

SECTION 32.2

     The cost of recording or filing the memorandum of lease referred to in
Section 32.1 shall be paid by Tenant.

including reasonable attorney fees and charges incurred as a result of a breach

performing any act (not including payment of money for Fixed Rent or Additional
Rent) required hereunder by reason of strikes or lock-outs, inability to procure
materials, failure of power, laws or regulations of Governmental Authorities,
riots, insurrection or war or acts of God, then performance of such act shall be
excused for the period of the delay and the period for the performance of any
such act shall be extended for a period equivalent to the period of such delay.

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

SECTION 46.1

          (a)  Provided this Lease is in full force and effect and no Event of
Default exists immediately prior to (i) the date Tenant delivers to Landlord the
First Election Notice (as hereinafter defined) and (ii) the expiration of the
initial term of this Lease, Tenant shall have the option (the "First Renewal
Option") to renew the term of this Lease (the "First Renewal Option") for all of
the Demised Premises for an additional five (5) year term (the "First Renewal
Term") commencing on the date (the "First Renewal Term Commencement Date")
following the Expiration Date of the initial term of this Lease and ending on
the date immediately prior to the fifth (5th) anniversary of the First Renewal
Term Commencement Date (which date shall hereupon be and become the Expiration
Date of this Lease).  The First Renewal Option shall be exercised by written
notice (the "First Election Notice") to Landlord delivered no later than six (6)
months prior to the Expiration Date of the initial term of this Lease.  The
annual Fixed Rent for the First Renewal Term shall be equal to the fair market
rental value of the Demised Premises as determined pursuant to the provisions of
Section 46.3(b) hereof.

          (b)  Provided that Tenant has exercised the First Renewal Option and
provided further that this Lease is in full force and effect and no Event of
Default exists immediately prior to (i) the date Tenant delivers to Landlord the
Second Election Notice (as hereinafter defined) and (ii) the expiration of the
First Renewal Term, Tenant shall have the option to renew the term of this Lease
(the "Second Renewal Option") for all of the Demised Premises for an additional
five (5) year term (the "Second Renewal Term") commencing on the date (the
"Second Renewal Term Commencement Date") immediately following the Expiration
Date of the First Renewal Term and ending on the date immediately preceding the
fifth (5th) anniversary of the Second Renewal Term Commencement Date (which date
shall thereupon be and become the Expiration Date of this Lease).  The Second
Renewal Option shall be exercised by written notice (the "Second Election
Notice") to Landlord delivered no later than six (6) months prior to the
expiration of the First Renewal Term.  The annual Fixed Rent for the Second
Renewal Term shall be determined pursuant to the provisions of Section 46.3(c)
hereof.

          (c)  Provided that Tenant has exercised the First and Second Renewal
Options and provided further that this Lease is in full force and effect and no
Event of Default exists immediately prior to (i) the date Tenant delivers to
Landlord the Third Election Notice (as hereinafter defined) and (ii) the
expiration of the Second Renewal Term, Tenant shall have the option to renew the
term of this Lease (the "Third Renewal Option") for all of the Demised Premises
for an additional five (5) year term (the "Third Renewal Term") commencing on
the date (the "Third Renewal Term Commencement Date") immediately following the
Expiration Date of the Second Renewal Term and ending on the date immediately
preceding the fifth (5th) anniversary of the Third Renewal Term Commencement
Date (which date shall thereupon be and become the Expiration Date of this
Lease).  The Third Renewal Option shall be exercised by written notice (the
"Third Election Notice") to Landlord delivered no later than six (6) months
prior to the expiration of the Second Renewal Term. The annual Fixed Rent for
the Third

                                      53.
<PAGE>

Renewal Term shall be equal the fair market rental value of the Demised Premises
as determined pursuant to the provisions of Section 46.3 (b) hereof.

SECTION 46.2

     This Lease, as so extended during the applicable Renewal Term, shall be
upon the same terms and conditions as contained in this Lease except that the
annual Fixed Rent for the First and Third Renewal Terms shall be a sum equal to
the then fair market rental value of the Demised Premises, determined as of the
commencement date of the respective Renewal Term assuming all of the terms set
forth herein and the annual Fixed Rent for the Second Renewal  Term shall be as
determined pursuant to Section 46.3(c).

SECTION 46.3

     The exercise of any of the Renewal Options shall only be effective upon,
and in strict compliance with, the following terms and conditions:

          (a) Each Renewal Option must be exercised in the manner specifically
set forth for such Option in Section 46.1 hereof or such option shall be deemed
waived and all of Tenant's rights with respect thereto shall wholly cease,
terminate and expire.  Time shall be of the essence in connection with the
exercise of any Renewal Option and the delivery of any Election Notice by Tenant
hereunder.  Any such Election Notice shall be irrevocable by Tenant upon
delivery.  If Tenant shall fail to duly exercise any Renewal Option, Tenant
agrees upon request of Landlord to confirm such non-exercise in writing, but
failure to do so by Tenant shall not operate to revive any rights of Tenant
under this Article.

          (b) Landlord and Tenant shall seek to agree as to the amount of such
fair market rental value for the Demised Premises, taking into consideration the
fair market rental value of comparable properties in the Minneapolis-St. Paul in
comparable condition available for a comparable term and any commissions payable
by Landlord to the Broker.  The determination of fair market rental value shall
exclude any increase in value as a result of improvements made after the
Commencement Date if such improvements were not made at Landlord's expense.  If
Landlord and Tenant shall not agree as to such fair market rental value by the
date which is two (2) months after the Election Notice is given, then each of
Landlord and Tenant, by no later than three (3) months after the Election Notice
is given, shall simultaneously meet and exchange notices setting forth in such
notices the annual fair market rental value that such party believes is the
basis for the Fixed Rent which should be paid by Tenant hereunder and in such
event said annual fair market rental value shall be determined by arbitration as
hereinafter in this Article provided.  In no event shall the annual Fixed Rent
for the First and Third Renewal Terms be less than the annual Fixed Rent for the
last Lease Year of the immediately preceding term.

          (c) The annual Fixed Rent commencing on the first day of the Second
Renewal Term and ending on the last day of the Second Renewal Term shall be an
amount equal to (i) the annual Fixed Rent for the First Renewal Term, plus (ii)
an amount equal to the greater of (A) five percent (5%) of the annual Fixed Rent
for the First Renewal Term or (B) the annual Fixed Rent for the First Renewal
Term multiplied by the percentage by which the CPI (as hereinafter

                                      54.
<PAGE>

defined) in June 2024 exceeds the CPI in June 2019. As used in this Lease, the
term "CPI" means the Consumer Price Index for All Items For All Urban Consumers
for Minneapolis, Minnesota published by the Bureau of Labor Statistics of the
U.S. Department of Labor with a 1993-95 = 100 base; provided, however, that (i)
                                                    --------  -------
if such index (or any index substituted therefor as hereinafter provided) shall
cease to be published, then for the purposes of this Lease there shall be
substituted for such index another index of a similar kind published by a
governmental or other nonpartisan organization as may be reasonably selected by
Landlord, and (ii) if there is any change in the manner of computation of any
such index, then for the purposes of this Lease such index as so changed shall
be substituted for the index in effect prior thereto and appropriate adjustments
shall be made to make the changed index comparable to the previous index.

SECTION 46.4

     If Landlord and Tenant shall be unable to agree as to the annual fair
market rental value as set forth in Section 46.3(b), then and in such event said
annual fair market rental value for the Demised Premises shall be determined by
arbitration with three (3) arbitrators selected in accordance with the
provisions of Section 10.5 except that the arbitrators so specified in such
notices shall be licensed appraisers doing business in the City of Minneapolis,
State of Minnesota, and having not less than ten (10) years' active experience
as appraisers of said City and State.  In making their determinations, the
arbitrators shall consider the criteria set forth in Section 46.3(b) and follow
the directions set forth in this Article.  Each arbitrator shall independently
determine the fair market rental value within thirty (30) days after being
selected and each shall simultaneously deliver its report of the fair market
value to Landlord and Tenant.  The two (2) closest determinations of fair market
value shall be averaged, and said average shall be deemed the fair market rental
value for purposes of this Lease.  The third determination of fair market rental
value shall be ignored.

SECTION 46.5

          (a) If on the commencement date of the First or Third Renewal Terms,
the amount of the Fixed Rent payable during such Renewal Term in accordance with
the foregoing paragraphs of this Article shall not have been determined, then,
pending such determination, Tenant shall pay Fixed Rent at the rate which is the
average of the rates proposed by Landlord and Tenant for that Renewal Term (the
"Temporary Rate").  After the determination by arbitration of the annual fair
market rental value of the Demised Premises, if such rental value is greater or
less than the "Temporary Rate," Landlord shall promptly pay to Tenant the excess
of the Temporary Rate over (or Tenant shall promptly pay to Landlord the
shortfall of the Temporary Rate below) the rental value determined by the
arbitration, together with interest at the Prime Rate on the amount so paid; and
the Fixed Rent so determined by the arbitration shall be payable during that
Renewal Term.

          (b) Upon determination of the Fixed Rent for each Renewal Term,
Landlord and Tenant shall execute, acknowledge and deliver to each other an
agreement specifying the amount of the Fixed Rent for such Renewal Term (but any
failure to execute such an agreement shall not affect Tenant's obligation to pay
and Landlord's right to receive such Fixed Rent).

                                      55.

                                PURCHASE OPTION
                                ---------------

          (a) Provided this Lease is in full force and effect and no Event of
Default exists hereunder and subject to the other terms and conditions of this
Article 47, Tenant shall have an option (the "Purchase Option") to purchase from
Landlord either on the twenty-fourth (24th) or thirty-sixth (36th) month
anniversary of the Commencement Date (either date being referred to herein as
the "Purchase Date") the Demised Premises and all other assets acquired by
Landlord from Tenant pursuant to the purchase agreement (the "Original Purchase
Agreement") dated as of September __, 1999, between Landlord, as purchaser, and
Tenant, as seller (the Demised Premises and such other assets being referred to
herein as the "Assets").  The Purchase Option shall be exercised by written
notice (the "Purchase Option Notice") delivered to Landlord no later than the
date which is six (6) months prior to the Purchase Date.  Time shall be of the
essence in connection with the exercise of the Purchase Option and the delivery
of notice to exercise the Purchase Option shall be irrevocable upon delivery.

          (b) The purchase price for the purchase by Tenant of the Assets
pursuant to the terms of this Article 47 shall be $45,600,000.00 (the "Purchase
Option Price") less any amounts applied thereto pursuant to terms of this Lease
which amount shall be paid to Landlord by wire transfer in immediately available
New York funds on the Purchase Option Closing Date (as defined herein).   Tenant
shall execute and deliver to Landlord within ten (10) days after the Purchase
Date a purchase agreement (the "Purchase Option Purchase Agreement") containing
representations and warranties substantially the same form as in the Original
Purchase Agreement, except to the extent necessary to make the representations
and warranties contained in the Original Purchase Agreement true, complete and
correct in all material respects.  The Purchase Option Purchase Agreement shall
otherwise be in form and content reasonably acceptable to Landlord and Tenant
and shall be consistent with typical commercial real estate purchase agreements
by and between institutional commercial real estate buyers and sellers desiring,
but under no compulsion, to buy and sell.  If Landlord and Tenant cannot agree
as to the terms and conditions of such agreement, the parties shall submit such
disagreements to arbitration as contemplated in Section 10.5 above.  In no
event, however, shall Landlord have any termination rights under the Purchase
Option Purchase Agreement except in the event of Tenant's default and failure to
cure under the terms and conditions of the Purchase Option Purchase Agreement.

          (c) The closing (the "Purchase Option Closing") of the sale under the
Purchase Option Purchase Agreement shall occur on or before the date (the
"Purchase Option Closing Date") which is the later of ten (10) days after mutual
execution and delivery of the Purchase Option Purchase Agreement or thirty (30)
days after the Purchase Date.  The conveyance documents delivered pursuant to
the Purchase Option Purchase Agreement shall be in substantially the same form
as the conveyance documents delivered pursuant to the Original Purchase
Agreement.  If the Purchase Option Closing shall not occur on or before the
Purchase Option Closing Date for any reason except by reason of force majeure or
Landlord's default under the Purchase Option Purchase Agreement, the Purchase
Option, at Landlord's option, shall be void and of no further effect.  If
Landlord elects to void the Purchase Option Purchase

<PAGE>

Agreement pursuant to the foregoing sentence, the term of this Lease shall
continue, unaffected by such election, pursuant to the terms and conditions of
this Lease. Notwithstanding anything to the contrary contained in the Purchase
Option Purchase Agreement, Landlord and Tenant shall have the right to
specifically enforce the terms of the Purchase Option Purchase Agreement.

          (d) Tenant and Landlord shall each be responsible for all costs and
expenses incurred by such party in connection with the consummation of the
transactions contemplated under the Purchase Option Purchase Agreement,
including without limitation, title and survey costs, engineering and
environmental inspections and any and all transfer taxes due in connection
therewith, unless otherwise set forth in the Purchase Option Purchase Agreement.

          (e) The provisions of this Article 47 shall inure to the benefit of
Tenant and its successors and assigns as Tenant hereunder and no other Person
shall have the right to exercise the Purchase Option.

                                  ARTICLE 48


                                  PUT OPTION
                                  ----------

          (a) Landlord shall have an option (the "Put Option") to require Tenant
to purchase the Assets from Landlord at any time after the thirty-sixth (36th)
month anniversary of the Commencement Date.  The Put Option shall be exercised
by written notice (the "Put Option Notice") delivered to Tenant.

          (b) The purchase price for the purchase by Tenant of the Assets
pursuant to the terms of this Article 48.1 shall be $41,800,000.00 (the "Put
Option Purchase Price") less any amounts applied thereto pursuant to terms of
this Lease which amount shall be paid to Tenant by wire transfer on the Purchase
Option Closing Date.  Landlord shall execute and deliver to Tenant within ten
(10) days after the Purchase Date a purchase agreement (the "Put Option Purchase
Agreement") containing representations and warranties substantially the same
form as in the Original Purchase Agreement, except to the extent necessary to
make the representations and warranties contained in the Original Purchase
Agreement true, complete and correct in all material respects.  The Put Option
Purchase Agreement shall otherwise be in form and content reasonably acceptable
to Landlord and Tenant and shall be consistent with commercial real estate
purchase agreements by and between institutional commercial real estate buyers
and sellers desiring, but under no compulsion, to buy and sell.  If Landlord and
Tenant cannot agree as to the terms and conditions of such agreement, the
parties shall submit such disagreements to arbitration as contemplated in
Section 10.5 above.  In no event, however, shall Landlord have any termination
rights under the Put Option Purchase Agreement except in the event of Tenant's
default and failure to cure under the terms and conditions of the Put Option
Purchase Agreement.

          (c) The closing (the "Put Option Closing") of the sale under the Put
Option Purchase Agreement shall occur on a date (the "Put Option Closing Date")
which is no earlier than one hundred eighty (180) days and no later than two
hundred seventy (270) days after Tenant's receipt of the Put Option Notice, as
determined in a notice to be delivered by Tenant to Landlord within sixty (60)
days after Tenant's receipt of the Put Option Notice.  The conveyance

                                      57.
<PAGE>

documents delivered pursuant to the Put Option Purchase Agreement shall be in
substantially the same form as the conveyance documents delivered pursuant to
the Original Purchase Agreement.

          (d) Tenant and Landlord shall each be responsible for all costs and
expenses incurred by or on behalf of such party in connection with the
consummation of the transactions contemplated under the Put Option Purchase
Agreement, including without limitation, title and survey costs, engineering and
environmental inspections and any and all transfer taxes due in connection
therewith, unless otherwise set forth in the Put Option Purchase Agreement.

          (e) The provisions of this Article 48 shall inure to the benefit of
Landlord and its successors and assigns as Landlord hereunder.

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

          THIS TENANT ESTOPPEL CERTIFICATE (this "Certificate") is made by
WAM!NET INC., a Minnesota corporation, on behalf of itself and its successors
and assigns ("Tenant"), for the benefit of CCPRE-EAGAN, LLC, a Delaware limited
liability company ("Landlord") and to ____________________________ [specific
                                                                    --------
lender or investor supplying financing to Landlord] ("Lender"), with the
- ---------------------------------------------------
understanding that Purchaser and Lender and their respective counsel will rely
on this Certificate in connection with the acquisition and financing of the
premises located at 655 Lone Oak Drive, Eagan, Minnesota (the "Property").
Tenant hereby certifies as follows:

defined herein shall have the meaning given to such terms in the Lease.  The
Lease is the entire agreement between Landlord (or any affiliated party) and
Tenant (or any affiliated party) pertaining to the leasing or occupancy of the
Premises (as defined herein).  There are no modifications, amendments,
supplements, renewals or assignments of the Lease except as may be otherwise set
forth on Exhibit B.  The Lease is in full force and effect in accordance with
         ---------
its terms.  There are no other oral or written side agreements, representations
or warranties by Landlord which entitle Tenant to payments or credits from
Landlord or which entitle Tenant to expand or contract the Premises or to extend
or contract the term of the Lease.  The Lease has been duly executed and
delivered by, and is a binding obligation of, Tenant.

          2.  Leased Premises.  The premises covered by the Lease (the

          8.  No Landlord Defaults.  To the best of Tenant's knowledge, all
              --------------------
obligations of Landlord under the Lease have been performed through the date
hereof, and no event has occurred and no condition exists that, with the giving
of notice or lapse of time or both, would constitute a default by Landlord under
the Lease.  To the best of Tenant's knowledge, there are no offsets or defenses
that Tenant has against the full enforcement of the Lease by Landlord.

          9.  No Tenant Defaults.  To the best of Tenant's knowledge, Tenant is

amendment has been consented to in writing by the Landlord.

              ---------------
further agrees that, from and after the date hereof, the Tenant shall not pay
any rent under the Lease more than thirty (30) days in advance of its due date.

          13. Successors and Assigns.  This Certificate is made for the benefit
              ----------------------
of, and may be relied upon by, the Landlord and the Lender and their respective
successors and assigns.

contract the term of the Lease. The Lease has been duly executed and delivered
by, and is a binding obligation of, Tenant.

     2. Leased Premises. The premises covered by the Lease (the "Premises")

of five percent (5%) or more in the operating expenses as set forth on the _____

Tenant's rent obligations under any other lease; and Tenant has not advanced any

from, or set off against, future rent payments.

of Landlord under the Lease have been performed through the date hereof, and no
event has occurred and no condition exists that, with the giving of notice or
lapse of time or both, would constitute a default by Landlord under the Lease.
To the best of Tenant's knowledge, there are no offsets or defenses that Tenant
has against the full enforcement of the Lease by Landlord.

     9. No Tenant Defaults. To the best of Tenant's knowledge, Tenant is not in

Tenant has no present intentions of doing so, and no such proceeding has been
commenced against Tenant seeking such relief, and Tenant has no knowledge that
any such proceeding is threatened.

     10. Purchase Options. Tenant does not have any right or option to purchase
all or any part of the Property except as expressly set forth in the Lease.

             NONDISTURBANCE, SUBORDINATION AND ATTORNMENT AGREEMENT
             ------------------------------------------------------

     THIS AGREEMENT (this "Agreement") is made as of the ___ day of September
1999, between CCPRE-EAGAN, LLC, a Delaware limited liability company, having an
address c/o Chase Capital Partners, 380 Madison Avenue, New York, New York
("Ground Lessor"), WAM!NET INC., a Minnesota corporation, having an address at
655 Lone Oak Parkway, Eagan, Minnesota ("Landlord") and SILICON GRAPHICS, INC. a
Delaware corporation, having an address at 655 Lone Oak Parkway, Eagan,
Minnesota ("Tenant").

                              W I T N E S S E T H:

     WHEREAS, Landlord and Tenant are parties to (i) that certain lease dated as
of March 4, 1999 with respect to certain premises (the "Premises") at the
corporate campus located at 655 Loan Oak Parkway, Eagan, Minnesota (the
"Project") (said lease, as the same may be amended, modified or supplemented
subject to and in accordance with the terms of this Agreement being referred to
herein as the "Lease"); and, (ii) that certain property management agreement
(the "Property Management Agreement") dated as of March 4, 1999.

     WHEREAS, Ground Lessor has acquired fee title to the Project from Landlord
pursuant to a deed dated September ____, 1999 and has entered into a lease (the
"Master Lease") dated as of the date hereof with Landlord pursuant to which
Ground Lessor will lease the Project to Landlord, the term of which Master Lease
extends beyond the term of the Lease; and

     WHEREAS, Tenant has agreed to subordinate the Lease and Ground Lessor has
agreed to grant nondisturbance and recognition to Tenant on the terms and
conditions contained herein.

     NOW, THEREFORE, in consideration of the premises and the agreements of the
parties contained herein, the parties hereto hereby covenant and agree as
follows:

     Section 1. Subordination. Tenant agrees that the Lease is and shall be
subject and subordinate to the Master Lease and to all renewals, amendments,
modifications, supplements, consolidations, replacements and extensions thereof,
provided that, as between Landlord and Tenant, nothing contained in this
Agreement shall be deemed to affect the obligations of Landlord or the rights of
Tenant under the Lease.

     Section 2. Nondisturbance. Ground Lessor hereby agrees that so long as (i)
the Lease shall be in full force and effect and (ii) Tenant shall not be in
default in the payment of Base Rent or Additional Rent or other charges due
under the Lease or in default in the performance or observance of any of the
other terms, covenants and
<PAGE>

conditions of the Lease, in each case, beyond any applicable notice and cure
periods (the "Nondisturb Conditions"), (a) Ground Lessor shall not join Tenant
as a party defendant in any action or proceeding which may be instituted or
taken by Ground Lessor under the Master Lease, by reason of any default by
Landlord thereunder or any financing instrument or collateral, to terminate the
Master Lease, to remove or evict Landlord or to recover possession of the
Premises, unless required by law in order to make such action or proceeding
effective and then only for technical purposes and not for removal of Tenant or
adversely affecting any interest of Tenant in the Premises or the Project, (b)
Tenant shall not be evicted from the Demised Premises, and (c) Tenant's estate
under the Lease shall not be diminished, interfered with, disturbed or
terminated and, subject to the provisions of Section 2 and Section 4 of this
Agreement, Ground Lessor shall recognize the Lease and Tenant's rights
thereunder and under the Property Management Agreement.

     Section 3. Notices to Ground Lessor.

     (a) Tenant hereby agrees that in the event of any act or omission by
Landlord which would give Tenant the right, either immediately or after the
lapse of a period of time, to terminate the Lease, or to claim a partial or
total eviction, Tenant shall not exercise any such right (a) until it has given
written notice of such act or omission to Ground Lessor, and (b) until a
reasonable period for remedying such act or omission shall have elapsed
following such giving of notice (but in no event less than thirty (30) days).
Tenant from and after the date hereof shall send a copy of any notices under the
Lease to Ground Lessor at the same time such notice or statement is sent to
Landlord under the Lease and agrees that, notwithstanding any provisions of the
Lease to the contrary, such notice shall not be effective unless Ground Lessor
shall have been given such notice and shall have failed to cure such default as
herein provided. All notices given under this Agreement shall be sent by
certified or registered mail, postage prepaid, return receipt requested, or
shall be delivered to the parties at the addresses set forth above (or at such
other addresses as the parties hereto shall specify in a written notice to the
other parties at the addresses specified herein). Any notices hereunder shall be
deemed to be given on the earlier to occur of (a) the day of receipt or (b)
three (3) days after deposit in the mail. No cure of Landlord's default by
Mortgagee shall be deemed an assumption of Landlord's other obligations under
the Lease and no right of Mortgagee hereunder to receive any notice or to cure
any default shall be deemed to impose any obligation on Mortgagee to cure (or
attempt to cure) any such default.

     (b) Tenant agrees, from time to time, to state in writing to Ground Lessor,
upon request, but not more than twice a year, whether or not, to the best of
Tenant's actual knowledge, any default on the part of Landlord exists under the
Lease and the nature of any such default.

     Section 4. Attornment. Tenant and Ground Lessor hereby agree that, in the
event by reason of default on the part of Landlord under the Master Lease or by
reason of the termination or surrender of the Master Lease, Ground Lessor shall
enter into and become possessed of the Premises or shall otherwise succeed to
Landlord's interest under the
<PAGE>

Lease (the date of such event shall be deemed the "Attornment Date"), then, so
long as the Nondisturb Conditions shall then be satisfied, the Lease shall
continue as a direct lease between Ground Lessor and Tenant upon all of the
terms, covenants, conditions and agreements as set forth in the Lease, and
Tenant agrees to be bound thereby and to attorn to Ground Lessor and recognize
Ground Lessor as its landlord and Ground Lessor agrees to be bound thereby and
recognize Tenant as its tenant thereunder provided, however, that Ground Lessor
shall not:

          (a) be liable for any act or omission or negligence of any prior
     landlord under the Lease (including Landlord) except that nothing herein
     shall be construed to relieve Ground Lessor of liability in respect of any
     defaults under the Lease after the Adornment Date, but then only as if the
     same first occurred on the Attornment Date or of liability in respect of
     the negligence or willful misconduct of Ground Lessor occurring prior to
     the Attornment Date;

          (b) be subject to any counterclaim, offset or defense which
     theretofore accrued to the Tenant against any prior Landlord under the
     Lease;

          (c) be bound by any amendment, modification, cancellation or surrender
     of the Lease not entered into or permitted pursuant to the specific terms
     of the Lease and entered into without the prior written consent of
     Landlord, but only if the same is prohibited by the terms of the Lease;

          (d) be bound by any payment of Base Rent or Additional Rent for more
     than one (1)month in advance;

          (e) be liable for any security deposit given by Tenant under the
     Lease, unless and to the extent actually received by Ground Lessor.

Upon the request of either Tenant or Ground Lessor, Ground Lessor or Tenant,
respectively, shall promptly execute and deliver to the other an agreement or
other instrument in recordable form which may be necessary or appropriate to
evidence such attornment and recognition.

     Section 5. Collection of Rent. Tenant acknowledges that pursuant to the
Master Lease, the Ground Lessor may elect to collect rent and all other sums due
under the Lease under certain circumstances. In the event that the Ground Lessor
notifies Tenant of its election to collect rent or other charges under the
Master Lease, then from and after the such election, until further notice from
Ground Lessor, Tenant shall pay its Base Rent, Additional Rent and all other
sums due under the Lease directly to Ground Lessor; provided however, such
receipt of rents and other sums, moneys and other amounts shall not relieve
Landlord of its obligations under the Lease, and Tenant shall continue to look
to Landlord only for performance thereof; provided that Tenant shall retain all
of its rights to the extent Landlord shall fail to pay or perform such
obligations. Tenant further agrees that, from and after the date that Ground
Lessor notifies Tenant that there has been an
<PAGE>

event of default under the Master Lease, that any notice, demand approval,
consent, election, determination, waiver or other action given or taken by
Ground Lessor or in respect of the Lease from time to time shall have the same
force and effect as a notice, demand, approval, consent, election,
determination, waiver or other action or taken by Landlord thereunder in respect
of the subject matter thereof and that, in the event of an inconsistent notice,
demand, approval, consent, election, determination, waiver or other action given
or taken from or by Landlord or Ground Lessor, the notice, demand, approval
consent, election, determination, waiver or other action given or taken from or
by Ground Lessor shall control and be dispositive and binding on Tenant for all
purposes of the Lease and Landlord hereby agrees that Tenant is released from
any payment owed to Landlord which Tenant makes to Ground Lessor pursuant to the
Master Lease.

     Section 6. New Lease. Notwithstanding anything herein or in the Lease to
the contrary, in the event that the Lease shall continue as a direct Lease
between Ground Lessor and Tenant:

          (a) Ground Lessor shall thereafter have the right to enter into a new
     ground lease of the Premises and to substitute the tenant under such new
     ground lease as the landlord under the Lease provided that any person or
     entity so substituted shall agree to be bound by the terms of this
     Agreement. In such event, Ground Lessor shall have no obligation, nor incur
     any liability, for any obligations under the Lease accruing after such
     substitution, and Ground Lessor shall be released and discharged therefrom,
     but such obligations shall be deemed assumed by and binding upon such
     successor to Ground Lessor; and

          (b) Ground Lessor's obligations under the Lease, as modified hereby,
     or under any new ground lease entered into pursuant to Section 6(a), shall
     continue only during the period Ground Lessor owns the Demised Premises,
     and in the event the Demised Premises are sold or otherwise transferred,
     Ground Lessor shall have no obligation, nor incur any liability, for any
     obligations under the Lease or under any such new ground lease entered into
     thereafter accruing, and Ground Lessor shall be released and discharged
     therefrom, but such obligations shall be deemed assumed by and binding upon
     such successor to Ground Lessor.

     Section 7. No Changes to Lease. The Lease constitutes an inducement to the
Ground Lessor to enter into this Agreement. Consequently, Tenant shall not,
without obtaining the prior written consent of Ground Lessor, (i) enter into any
agreement renewing, extending, amending, canceling, modifying, terminating or
surrendering the Lease which are not entered into or permitted pursuant to the
specific terms of the Lease except for that certain proposed lease amendment, a
true, complete and correct copy of which is attached hereto as Exhibit A,
provided that the final amendment entered into does not differ in any material
respect from such proposed amendment, (ii) prepay any of the Base Rent and one
billing period of additional rent due under the Lease for more than one (i)
month in advance of the due dates thereof, (111) voluntarily surrender the
Premises or terminate the Lease without cause or shorten the term thereof,
except as and
<PAGE>

to the extent specifically provided for in the Lease, or (iv) assign the Lease
or sublet the Premises or any part thereof other than pursuant to the provisions
of the Lease and any such amendment, modification, termination, prepayment,
voluntary surrender, assignment or subletting, without Ground Lessor's prior
consent, shall not be binding upon Ground Lessor, but shall not otherwise have
any effect on the rights and obligations of the parties hereunder.

               (i) agrees that upon notice from Ground Lessor, or its successors
          or assigns, all rents and other sums, moneys and other amounts due or
          to become due and (including, without limitation, all base rent and
          additional rent thereunder) shall be paid to Ground Lessor or as
          otherwise directed by Ground Lessor;

               (ii) agrees that Ground Lessor shall not, by reason of the
          Assignment of Leases, be subject to any obligation, duty or liability
          under the Lease, except that when Ground Lessor is exercising rights
          under the Lease, it shall do so in accordance with the terms and
          conditions thereof and, to the extent applicable, this Agreement.

     Section 8. Satisfaction. Tenant agrees that this Agreement, when executed,
acknowledged and delivered by Ground Lessor satisfies any condition or
requirement in the Lease relating to the delivery of a nondisturbance agreement
by Landlord in connection with Landlord's sale of the Premises to the Ground
Lessor.

     Section 9. Miscellaneous.

          (a) This Agreement shall be binding upon and inure to the benefit of
     the respective successors and assigns of the parties hereto and may not be
     modified or terminated orally.

          (b) This Agreement and the rights and obligations of the parties
     hereunder shall be governed by and construed in accordance with the laws of
     the State of Minnesota.

          (c) This Agreement may be signed in counterparts.

          (d) This Agreement may not be modified, amended or terminated unless
     in writing and duly executed by the party against whom the same is sought
     to be asserted and constitutes the entire agreement between the parties
     with respect to the subject matter hereof.
