(1) BASIS OF PRESENTATION:

The accompanying unaudited financial statements of Vital Images, Inc. ("Vital
Images" or the "Company") have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the

opinion of management, all adjustments considered necessary, including items of
a normal recurring nature, for a fair presentation have been included. Operating
results for the three and nine months ended September 30, 1999 are not
necessarily indicative of the results that may be expected for the year ending

(3) NET LOSS PER SHARE:

For the three and nine months ended September 30, 1999 and 1998, net loss per
share is computed using the weighted average common shares outstanding during
the period.  Common share equivalents are not included in the net loss per share
calculations, since they are anti-dilutive.  Options to purchase 1,604,154
shares of the Company's common stock were outstanding as of September 30, 1999
and could potentially dilute net income per share in future periods if the
Company generates net income.


(4) COMPREHENSIVE INCOME:

During the nine months ended September 30, 1999 and 1998, total comprehensive
loss was $2,520,000 and $2,477,000, respectively.  There was no accumulated
other comprehensive income or loss as of September 30, 1999 and December 31,
1998.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS

Overview

Vital Images, Inc. (the "Company" or "Vital Images") develops, markets and
supports visualization and analysis software for clinical diagnosis, surgical
planning and medical research.  The Company believes that its high-speed
visualization technology and customized protocols cost-effectively bring 3D
visualization and analysis into the routine, day-to-day practice of medicine.
The Company, which operates in a single business segment, markets its products
to healthcare providers and to manufacturers of diagnostic imaging systems
through a direct sales force in the United States and independent distributors
in international markets.

Revenue

Revenue was $1,719,000 for the three months ended September 30, 1999 compared
with $1,250,000 for the three months ended September 30, 1998, a 37% increase.
For the nine months ended September 30, 1999 revenue was $4,578,000 compared
with $3,001,000 in the comparable nine-month period of the prior year, a 53%
increase. These increases were primarily the result of volume increases in
shipments of Vitrea(R), the Company's flagship medical visualization and
analysis product for radiological and surgical applications in the clinical
market. Software and hardware revenue from the Vitrea platform totaled
$1,335,000, or 78% of total revenue, and $3,453,000, or 75% of total revenue,
for the three and nine months ended September 30, 1999, respectively, compared
with $931,000, or 74% of total revenue, and $2,023,000, or 67% of total revenue,
for the three and nine months ended September 30, 1998, respectively. The Vitrea
platform includes hardware and software revenue from Vitrea, VScore(TM) and
Advanced 3DI(TM). VScore is the Company's newest 3D software product and is used
for coronary artery calcium scoring. Advanced 3DI is the Company's visualization
and analysis product for the ultrasound market, which is marketed exclusively by
ATL Ultrasound, Inc. There was also an increase in maintenance and services
revenue related to Vitrea sales for the three and nine months ended September
30, 1999, as compared with the comparable periods last year.

It is expected that, in general, total revenue will continue to increase in
future periods due to increased sales of Vitrea software and systems.  However,
actual annual and quarterly results could vary materially from the foregoing
forward-looking statement as a result of the timing of purchases by the
Company's major customers, the growth in the medical visualization market,
increased competition, the continued need for product acceptance and other
issues that generally impact the purchasing patterns of the Company's customers.

Gross Margin

The gross margin percentage increased from 73% and 72% for the three and nine
months ended September 30, 1998, respectively, to 80% and 77% for the three and
nine months ended September 30, 1999, respectively, primarily as a result of
economies of scale in the cost of revenue structure related to license fees and
maintenance and services revenue.  A decrease in the percentage of revenue
derived from hardware, which has a lower gross margin percentage than license
fees and maintenance and services also contributed to the higher gross margin
percentage.  The Company anticipates that as volume from Vitrea software
increases as a percentage of the Company's product mix, the overall gross margin
percentage will trend up slightly from comparable prior years.  This forward-
looking statement will be influenced primarily by vendor discounts on the third
party hardware and peripheral components of the Vitrea system and on the
Company's product mix.

Sales and Marketing

Sales and marketing expenses increased to $830,000, or 48% of total revenue, for
the three months ended September 30, 1999 from $692,000, or 55% of total
revenue, for the three months ended September 30, 1998, a 20% increase.  For the
nine months ended September 30, 1999, sales and marketing expenses increased
32%, to $2,692,000, or 59% of total revenue, from $2,032,000, or 68% of total
revenue, for the nine months ended September 30, 1998.  The increases were
primarily due to increased compensation and employee costs as a result of
increased sales commission and additional personnel, as well as increases in
travel expenses related to selling and promoting the Vitrea product and an
increase in depreciation expense. These increases were partially offset by a
decrease in clinical collaboration costs.  The Company expects sales and
marketing costs to increase in future periods as a result of the cost of
additional sales personnel and increased marketing and promotional expenses for
Vitrea.

Research and Development

Research and development expenses increased 34% to $611,000, or 36% of total
revenue, for the three months ended September 30, 1999, compared with $456,000,
or 37% of total revenue, for the same period last year.  For the nine month
period ended September 30, 1999, research and development expenses increased 38%
to $1,865,000, or 41% of total revenue, from $1,354,000, or 45% of total
revenue, for the comparable period in the prior year.  The increases were
primarily due to increased compensation and employee costs resulting from
additional personnel and a decrease in the reimbursement of engineering costs
pursuant to a software development contract with ATL Ultrasound, Inc.  The
Company anticipates that research and development costs will increase in future
periods as future releases of Vitrea software are developed.

General and Administrative

General and administrative expenses increased to $406,000, or 24% of total
revenue, for the three months ended September 30, 1999, from $358,000, or 29% of
total revenue, for the three months ended September 30, 1998, a 13% increase.
For the nine months ended September 30, 1999, general and administrative
expenses increased 9%, to $1,562,000, or 34% of total revenue, from $1,433,000,
or 48% of total revenue, for the nine months ended September 30, 1998.  For both
the three and nine months ended September 30, 1999, compensation costs increased
primarily as a result of staffing additions.  For the nine months ended
September 30, 1999 there was an increase in personnel recruiting costs as
compared with the nine months ended September 30, 1998, due to hiring of
additional staff.  There were also increases in investor relations and
professional fees for both the three and nine months ended September 30, 1999 as
compared with the three and nine months ended September 30, 1998, primarily due
to increased activity in both these areas.  These increases were partially
offset by decreases in bad debt expense and, for the nine months ended September
30, 1999, costs associated with the resignation of the Company's former Chief
Executive Officer in the first quarter of 1998.  The Company also reduced the
estimated accrued costs related to the closing of its Iowa facility, resulting
in lower expenses for the three and nine months ended September 30, 1999,
primarily due to negotiating an early termination of the lease for that
facility.  The Company believes that general and administrative costs will
increase in future periods primarily due to increased compensation expense for
employees hired in 1998 that will be present for all of 1999 and additional new
hires in 1999.

Operating Losses

The increase in revenue from Vitrea shipments, net of the increased expenses
attributable to the development of the Company's infrastructure and the
continued development and promotion of the Vitrea product, resulted in decreased
operating losses of $466,000 and $2,595,000 for the three and nine months ended
September 30, 1999, respectively, compared with operating losses of $599,000 and
$2,665,000 for the three and nine months ended September 30, 1998, respectively.

Interest Income

Interest income was $20,000 and $79,000 for the three and nine months ended
September 30, 1999 compared with $58,000 and $207,000 for the comparable periods
in 1998.  The decreases in interest income were due to a lower balance of cash,
cash equivalents and marketable securities as a result of the use of cash to
fund the Company's operations.

Income Taxes

The income tax provisions for the three and nine months ended September 30, 1999
and 1998 consist solely of certain state minimum fees.  The Company has deferred
tax assets resulting primarily from net operating loss carryforwards for federal
income tax reporting purposes and unused research and development credits. A
valuation allowance has been established to completely reserve for the deferred
tax assets of the Company.

Liquidity and Capital Resources

As of September 30, 1999, the Company had $1,408,000 in cash and cash
equivalents.  The Company's working capital was $1,271,000 and the Company had
no material borrowings.  In March 1999, the Company entered into a
collateralized line of credit agreement with a bank for $950,000. Borrowings
under the agreement are limited to the lower of $950,000 or the Company's
borrowing base, which consists of a specified percentage of certain accounts
receivable.  The Company is also required to maintain a cash and cash
equivalents balance of at least $1,000,000 at the lending bank.  As of September
30, 1999, the Company's available borrowings under the agreement were $800,000.

Cash flows used in operations increased to $2,297,000 in the first nine months
of 1999 from $1,954,000 in the first nine months of 1998.  In both nine-month
periods cash flows were used primarily to fund operating losses, which were
partially offset by non-cash expenses for depreciation, amortization and stock
compensation.  Increases in accounts receivable and prepaid expenses and other
current assets reduced cash flows from operations for the nine months ended
September 30, 1999. An increase in accounts receivable reduced cash flows from
operations, while a decrease in prepaid expenses and other current assets
increased cash flows from operations for the nine months ended September 30,
1998.  Increases in current liabilities, primarily due to an increase in
deferred revenue, increased cash flows from operations in the nine months ended
September 30, 1999. Increases in current liabilities, due to increases in
accounts payable, accrued payroll and other current liabilities and deferred
revenue, increased cash flows from operations in the nine months ended September
30, 1998.

The increase in deferred revenue for the nine months ended September 30, 1999
was primarily due to volume increases in Vitrea sales and the increase in
accounts payable was due primarily to costs related to these sales.

Net investing activities provided $1,567,000 of cash in the nine months ended
September 30, 1999 and $1,967,000 of cash in the nine months ended September 30,
1998, primarily due to the conversion of marketable securities into cash. The
Company used cash to acquire property and equipment of $419,000 and $259,000 in
the nine months ended September 30, 1999 and 1998, respectively, primarily for
computer equipment to accommodate the increases in employee headcount.

Cash provided by financing activities totaled $387,000 and $84,000 for the nine
months ended September 30, 1999 and 1998, respectively, as a result of proceeds
from the sales of common stock under stock option plans.

The Company has never paid or declared any cash dividend and does not intend to
pay dividends in the near future. The Company has no current commitments for
material capital expenditures. The Company expects to use cash in the near term
as it continues to develop the infrastructure to support its business and
develop the market for its products.

The Company has signed a lease for new corporate headquarters commencing on
February 1, 2000. In anticipation of the move, it is expected that the Company
will commit to purchase between $400,000 and $500,000 of furniture and equipment
before the end of the first quarter of 2000. The Company expects to purchase
this furniture and equipment with a combination of cash and borrowings.

The Company expects that, in general, as the Company's revenues increase the use
of cash will decrease in future periods as compared with the three and nine
months ended September 30, 1999. If the Company's operations progress as
anticipated, of which there can be no assurance, management believes that its
cash and cash equivalents and borrowings available under the credit agreement
entered into in March 1999 should be sufficient to satisfy its cash requirements
for at least the next twelve months. If the Company continues to experience
operating losses at its current rate or the borrowings under the line of credit
are not available, the Company will need to raise additional capital within the
next six to twelve months.

The Company has identified emerging market opportunities in radiological
screening and surgical planning applications. In order to provide additional
capital to pursue these opportunities, as well as to provide additional working
capital, the Company has engaged a placement agent for the sale of up to
1,500,000 shares of the Company's common stock. There can be no assurance as to
the amount of proceeds, if any, which will actually be received by the Company
in the offering. Further, if the current offering is not consummated, or if
additional financing is required beyond the amounts received in the offering,
there can be no assurance that additional capital will be available on
acceptable terms or at all, and the failure to obtain any such capital may have
a material adverse effect on the Company's business.

Foreign Currency Transactions

Substantially all of the Company's foreign transactions are negotiated, invoiced
and paid in U.S. dollars.

Year 2000 Readiness

Many computer programs and embedded computer chips are unable to distinguish
between the year 1900 and the year 2000. Therefore, some computer hardware and
software will need to be modified prior to the year 2000 in order to remain
functional. This is commonly known as the Year 2000 ("Y2K") issue.

                                       11
<PAGE>

The Company has a formal program in place with an assigned Year 2000 project
team to ensure that its critical areas will operate normally at the turn of the
century. The goal of the Year 2000 team is to ensure that the Company's
equipment, systems and processes and those of its significant business partners
are sufficiently Year 2000 compliant such that no date/time issue will have any
material adverse impact on the products or services that the Company provides
its customers or the timely and accurate processing of transactions.

Throughout 1999, the Company has determined areas where contingency planning is
needed. The planning efforts included, but are not limited to, identification
and mitigation of potential serious business interruptions and establishing
crisis response processes to address unexpected problems.

The project team has identified its Y2K risks in the following four categories:
Company products, financial software, embedded chip technology and non-financial
software, and noncompliance by suppliers and customers.

Company Products. The Company has assessed the Y2K readiness of its software
products and has made the commitment that any product releases in 1999 and later
will be Y2K compliant. The Company has posted a table detailing the Y2K
readiness status of its products on its website at www.vitalimages.com.
                                                   -------------------
Management believes that a lack of Y2K readiness in any of its products, except
for Vitrea and VScore, would not have a material impact on the Company's results
of operations or financial condition. On March 31, 1999, the Company announced
the release of a Y2K compliant version of Vitrea. VScore was released in August
1999 and is also Y2K compliant.

Financial Software. During 1997, the Company purchased and installed a new
accounting software package. The Company has obtained a statement from the
vendor indicating that the software is Y2K compliant. The Company has also
tested the Y2K readiness of this software. This testing did not reveal any Y2K
compliance issues.

Embedded Chip Technology and Non-financial Software. The Company has assessed
its Y2K readiness with regard to critical and non-critical embedded chip
technology and non-financial software. The Company's assessment of its Y2K
readiness did not reveal any critical embedded chip technology or non-financial
software that was not Y2K compliant. The Company's assessment did reveal that
certain non-critical assets containing embedded chip technology and certain non-
financial software were not Y2K compliant. The Company has replaced or upgraded
these non-compliant assets and non-financial software products.

Noncompliance by Suppliers and Customers. The Company has evaluated its critical
suppliers and service providers to determine the state of their Y2K readiness.
The Company's evaluation did not reveal any material noncompliance issues
related to its critical suppliers and service providers. The Company does not
have any formal information concerning the Y2K compliance status of its
customers. If customers experience significant Y2K problems, they may choose to
delay or cancel orders for the Company's products. In the event that any of the
Company's significant suppliers or customers do not achieve Y2K compliance in a
timely manner, and the Company is unable to replace them with alternate
suppliers or customers, the Company's operations could be materially adversely
affected.

The costs incurred by the Company to date in addressing its Y2K readiness issues
are primarily non-incremental compensation costs and have not been material to
the Company's operating results. The Company currently estimates that the total
additional costs for addressing its internal Y2K readiness will not be material
to the Company's operating results. These costs are being expensed as they are
incurred. The Company plans to devote the necessary resources to resolve all
significant Y2K issues in a timely manner.

                                       12
<PAGE>

The Company's statements regarding its Y2K readiness are forward-looking
statements and are, therefore, subject to change as a result of known and
unknown factors. Both the Company's cost estimates and completion time frames
could be influenced by the Company's ability to successfully identify all Y2K
issues, the nature and amount of remediation required, the availability and cost
of trained personnel in this area and the Y2K success that key third parties and
customers attain. While these and other unforeseen factors could have a material
adverse impact on the Company's financial position, results of operations or
liquidity in future periods due to possible business disruptions caused by a
lack of third party Y2K readiness, management believes that it has implemented
an effective Y2K compliance program that will minimize the possible negative
consequences to the Company.

The Y2K readiness disclosure statement set forth above is a 'Year 2000 Readiness
Disclosure' under the federal Year 2000 Information and Readiness Disclosure
Act.

                     STANDARD OFFICE LEASE AGREEMENT (NET)


     THIS LEASE AGREEMENT (hereinafter called the "Lease Agreement" or "Lease")
made as of the 19th day of October, 1999, by and between ST. PAUL PROPERTIES,
INC., a Delaware corporation having offices at c/o United Properties, LLC, 3500
West 80th Street, Bloomington, Minnesota, 55431 (hereinafter called the
"Landlord"), and VITAL IMAGES, INC., a Minnesota corporation (hereinafter called
the "Tenant").

                                  WITNESSETH
                                  ----------

     FOR AND IN CONSIDERATION of the sum of One Dollar ($1.00) in hand paid by
each of the parties to the other, and other good and valuable consideration,
receipt and sufficiency of which is hereby acknowledged, Landlord does hereby
lease and let unto Tenant, and Tenant does hereby hire, lease and take from
Landlord, that area  crosshatched on Exhibit A-1 attached hereto, and by this
                                     -----------
reference incorporated herein, and described as Suite 200, 3300 Fernbrook Lane
North, containing approximately 24,323 net rentable square feet, (hereinafter
called the "Premises") at Plymouth Woods Office Center (hereinafter called the
"Building") in the City of Plymouth, County of Hennepin, State of Minnesota,
together with a non-exclusive right to use those areas of the Building (i) not
reserved for use by Landlord; and (ii) not leased or available for lease to
other tenants. The term Building as it is used herein shall consist of the land
and building(s) set forth in Exhibit A-2 hereto.  Notwithstanding the foregoing,
                             -----------
Landlord agrees that the number of rentable square feet in the Premises shall be
determined by measurements taken from the Working Drawings (as defined in the
Work Letter Agreement), which measurement shall be in accordance with the
measurement standards set forth in ANSI/BOMA Z.65.1-1989. To the extent that the
square footage of the Premises are other than 24,323 rentable square feet,
Landlord and Tenant agree that the annual and monthly Minimum Rental (as
hereinafter defined) will be modified to take such changes into account, it
being understood and agreed that the calculation of Minimum Rental shall be
based on a rental rate of (a) Thirteen and 25/100ths Dollars ($13.25) per
rentable square foot for the period from the Commencement Date through the
expiration of the thirty-sixth full calendar month of the Term (as hereinafter
defined); and (b) Fourteen and 00/100ths Dollars ($14.00) per rentable square
foot for the period from the first day of the thirty-seventh full calendar month
of the Term through the Expiration Date (as hereinafter defined).

ARTICLE 1 - TERM

     To have and to hold said Premises for a term of five (5) years and six (6)
months (the "Term"), commencing February 1, 2000 (the "Commencement Date") and
terminating July 31, 2005 (the "Expiration Date"), upon the rentals and subject
to the conditions set forth in this Lease Agreement, and the Exhibits attached
hereto.

Notwithstanding the foregoing, Tenant shall have the right to enter onto the
Premises on January 15, 2000, for the sole purpose of installation of fixtures,
furniture and telecommunications cabling, without payment of Base Rent or
Operating Costs (each as hereinafter defined), provided however that such entry
and installation shall be in accordance with Paragraph 8 of the Work Letter
Agreement, attached hereto as Exhibit B and made a part hereof (the "Work Letter
                              ---------
Agreement").

ARTICLE 2 - USE

     The Premises shall be used by Tenant solely for the purposes of general
office and for the purpose of storage.

ARTICLE 3 - RENTALS

     Subject to the provisions of Article 1 above, Tenant agrees to pay to
Landlord as minimum rental (hereinafter called "Minimum Rental") for the
Premises the following amounts:

     (a) For the period from the Commencement Date through the last day of the
          thirty-sixth (36th) full calendar month of the Term, the sum of
          $322,279.75 per annum, in monthly installments of $26,856.65; and

     (b) For the period commencing on the first day of the thirty-seventh (37th)
          full calendar month of the Term through the Expiration Date, the sum
          of $340,522.00 per annum, in monthly installments of $28,376.83.

The Minimum Rental shall be paid in equal monthly installments as provided
above, without notice set-off or demand, to be due and payable by Tenant in
advance on the first day of each calendar month during the Term of this Lease
Agreement, or any extension or renewal thereof, at the office of Landlord set
forth in the preamble to this Lease Agreement or at such other place as Landlord
may designate. In the event of any fractional calendar month, Tenant shall pay
for each day in such partial month a rental equal to 1/30 of the Minimum Rental.
Tenant agrees to pay, as Additional Rent, which shall be collectible to the same
extent as Minimum Rental, all amounts which may become due to Landlord hereunder
and any tax, charge or fee that may be levied, assessed or imposed upon or
measured by the rents reserved hereunder by any governmental authority acting
under any present or future law before any fine, penalty, interest or costs may
be added thereto for non-payment.
<PAGE>

Notwithstanding the foregoing, and in consideration of Tenant's performance of
all of its obligations hereunder throughout the Term, such performance being a
condition subsequent to the following abatement of Minimum Rental and Operating
Expenses (as hereinafter defined) it is hereby agreed that Landlord shall abate
all Minimum Rental and Operating Expenses for the first two full months of the
Term. It is understood and agreed that should an Event of Default (as
hereinafter defined) occur with respect to the performance of Tenant's
obligations hereunder, the total amount of all such abated Minimum Rental and
Operating Expenses shall, as of the date of such Event of Default become due and
owing to Landlord and shall be payable to Landlord on demand as Additional Rent
hereunder.

ARTICLE 4 - CONSTRUCTION

     Landlord shall cause the Premises to be constructed in accordance with the
terms and conditions of that certain Work Letter Agreement executed by Landlord
and Tenant in the form of Exhibit B attached hereto and made a part hereof.
                          ---------

ARTICLE 5 - POSSESSION

     (a) Subject to the Work Letter Agreement, Landlord shall deliver possession
of the Premises to Tenant on the Commencement Date. Delivery of possession prior
to the Commencement Date shall not affect the Expiration Date of this Lease
Agreement. Failure of Landlord to deliver possession of the Premises by the date
hereinabove provided, due to a holding over by a prior tenant, or any other
cause beyond Landlord's control, or time required for construction delays due to
material shortages, strikes, or acts of God, shall automatically postpone the
date of commencement of the Term of this Lease Agreement and shall extend the
termination date by periods equal to those which shall have elapsed between and
including the date hereinabove specified for commencement of the Term hereof and
the date on which possession of the Premises is delivered to Tenant. Except as
expressly provided herein, the rentals herein reserved shall commence on the
first day of the Term, provided, however, in the event of any occupancy by
Tenant prior to the beginning of the Term, such occupancy shall in all respects
be the same as that of a tenant under this Lease Agreement, and the rental shall
commence as of the date that Tenant enters into such occupancy of the Premises.
Provided further, that if Landlord shall be delayed in delivery of the Premises
to Tenant due to Tenant's failure to agree to the Plans or any delay caused by a
party employed by or the agent of Tenant, or by Tenant's failure to pay for the
costs of Tenant Improvements in excess of the Allowance (as defined in the Work
Letter Agreement), then in such case the rental shall be accelerated by the
number of days of such delay, and the rentals shall commence the same as if
occupancy had been taken by Tenant.  Landlord shall have no responsibility or
liability for loss or damage to fixtures, facilities or equipment installed or
left on the Premises. By occupying the Premises as a Tenant, or to install
fixtures, facilities or equipment, or to perform finishing work, Tenant shall be
conclusively deemed to have accepted the same and to have acknowledged that the
Premises are in the condition required by this Lease Agreement, except (i) items
which are not in compliance with Exhibit B and for which Tenant has given
                                 ---------
Landlord a written "punch list" within thirty (30) days after Tenant's first
occupancy of the Premises; and (ii) latent defects of which Tenant notifies
Landlord within one hundred eighty (180) days after the date Tenant first
occupies the Premises for the conduct of its business.

     Should the commencement of the rental obligations of Tenant under this
Lease Agreement occur for any reason on a day other than the first day of a
calendar month, then in that event solely for the purposes of computing the Term
of this Lease Agreement, the Commencement Date of the Term shall become and be
the first day of the first full calendar month following the date when Tenant's
rental obligation commences, or the first day of the first full calendar month
following the Commencement Date set out in Article 1 (if such is other than the
first date of a calendar month), whichever date is later, and the Expiration
Date shall be adjusted accordingly; provided however, that the Expiration Date
shall be the last day of a calendar month, which date shall in no event be
earlier than the termination date set out in Article 1, it being the intent of
the parties that Tenant shall lease the Premises for a term of sixty-six (66)
full calendar months. Immediately after Tenant's occupancy of the Premises
Landlord and Tenant shall execute a ratification agreement which shall set forth
the final commencement and termination dates for the Term and shall acknowledge
the Minimum Rental, the square footage of the Premises, and delivery of the
Premises in the condition required by this Lease Agreement, subject to
subparagraphs (i) and (ii) of the preceding paragraph of this subparagraph (a).

     (b) Landlord and Tenant agree that Landlord's ability to deliver possession
of the Premises to Tenant, on or before February 1, 2000, is a material
inducement to Tenant to enter into this Lease.  Tenant has requested that if
Landlord fails to deliver the Premises on or before February 1, 2000, and has
not delivered the Premises on or before August 1, 2000 (the "Outside Delivery
Date"),  that Tenant have the right to terminate this Lease Agreement, and
Landlord has agreed to such right to terminate provided that:

     (i)    Tenant is not then in default under this Lease;

     (ii)   no delays occur or have occurred as a result of subparagraphs
            (a) - (j) of Paragraph 1 of the Work Letter Agreement;

     (iii)  no Tenant Delays (as defined in the Work Letter Agreement) occur or
            have occurred; and
<PAGE>

     (iv)   no event of force majeure occurs or has occurred, it being
            understood and agreed that for the purposes of this Lease Agreement,
            force majeure shall include, without limitation, any cause beyond
            Landlord's control, including, without limitation, failure of the
            City of Plymouth to timely issue building permits, certificates of
            occupancy or the like, time required for construction delays due to
            any cause whatsoever, including, without limitation, material
            shortages, strikes or acts of nature,

     Any occurrence of any event described in (subparagraphs (i), (ii), (iii) or
(iv) above shall automatically postpone the Outside Delivery Date on a day-for-
day basis for the number of days attributable to such occurrence and shall
extend the Expiration Date to a day which is the last day of the sixty-sixth
full calendar month after the first day of the first full calendar month after
Landlord delivers the Premises to Tenant. Landlord and Tenant further agree that
if Landlord shall be delayed in delivery of the Premises to Tenant after
February 1, 2000, due to any event (x) described in subparagraphs (i), (ii) or
(iii) above, then the Commencement Date shall be deemed to be February 1, 2000,
and Minimum Rental and Operating Costs shall commence to accrue as of such date;
or (y) described in subparagraph (iv) above, then the Commencement Date shall be
postponed on a day-for-day basis for the number of days attributable to such
occurrence, and shall extend the Expiration Date to a day which is the last day
of the sixty-sixth full calendar month after the first day of the first full
calendar month after Landlord delivers the Premises to Tenant.

     Landlord and Tenant agree that if Landlord does not deliver the Premises on
or before the Outside Delivery Date, either party may, by written notice given
to the other party not later than August 8, 2000, terminate this Lease
Agreement, and upon such termination, this Lease Agreement shall be null and
void and of no further force or effect and the parties shall have no further
obligations to each other except as set forth in Paragraph 35 hereof, it being
understood and agreed that if the reason Landlord has not delivered the Premises
by the Outside Delivery Date arises from any cause other than Landlord's fault,
Landlord shall have no obligation to pay the Damage Amount (as hereinafter
defined). If this Lease Agreement is not terminated as provided in the preceding
sentence, this Lease Agreement shall continue in full force and effect and the
Commencement Date shall be the first day of the first full calendar month after
delivery of the Premises to Tenant, and the Expiration Date shall be the last
day of the sixty-sixth full calendar month after the Commencement Date, and the
payment of Minimum Rental and Operating Expenses shall commence on the date the
Premises are delivered to Tenant.

     Notwithstanding the foregoing, should Landlord fail to deliver the Premises
to Tenant on or before March 1, 2000, other than as a result of any of items
(i), (ii), (iii) or (iv) above, Landlord and Tenant agree that Landlord shall
pay to Tenant an amount (the "Damage Amount") equal to the sum of:

     (p)  the amount, if any, in excess of the amount payable by Tenant as of
          January 1, 2000, for base rent and other charges payable for the lease
          of Tenant's premises located at 3100 West Lake Street, Minneapolis,
          Minnesota (the "Lake Street Premises"); plus

     (q)  the cost, if any, of any move of Tenant's business from temporary
          premises to the Premises, but not the cost of any move from the Lake
          Street Premises to temporary premises,

each as confirmed by evidence reasonably satisfactory to Landlord, which Damage
Amount shall, in no event, exceed $13,440. Landlord and Tenant further agree
that, should Landlord be unable to deliver the Premises by March 1, 2000, then
Landlord shall have the right to either:

     (j)  provide Tenant with temporary premises, as to which Tenant shall be
          obligated to pay rent, real estate taxes and operating expenses in
          amounts not to exceed the amounts therefor payable for the Lake Street
          Premises as of January 1, 2000; or

     (k)  negotiate with the landlord of the Lake Street Premises with respect
          to the amount of so-called "holdover rent" otherwise payable by Tenant
          with respect thereto after February 29, 2000.

To the extent Landlord provides Tenant with temporary premises as contemplated
by subparagraph (j) above, or makes any "holdover rent" payment to the Lake
Street Premises landlord, Landlord shall not be obligated to make any payment of
the Damage Amount to Tenant and the abatement of Minimum Rental and Operating
Expenses contemplated by Article 3 hereof shall apply to the first two full
calendar months of Tenant's occupancy of the Premises, which abatement shall be
subject to the terms and conditions set forth in said Article 3. Payment of the
Damage Amount, to the extent payable hereunder, shall be Tenant's sole remedy
for Landlord's failure to deliver the Premises on March 1, 2000.

ARTICLE 6 - TENANT'S PRO RATA SHARE OF REAL ESTATE TAXES AND OPERATING EXPENSES

     A.   During each full or partial calendar year during the Term of this
Lease Agreement, Tenant shall pay to Landlord, as Additional Rental, an amount
equal to the Real Estate Taxes and Operating Expenses (both as hereinafter
defined) per square foot of rentable area in the Building multiplied by the
number of square feet of rentable area in the Premises ("Proportionate Share")
prorated for the period that Tenant occupied the Premises. Notwithstanding the
preceding sentence, Tenant's Proportionate Share
<PAGE>

of the following Operating Expenses shall be computed on the basis of the cost
of said expenses per rentable square foot of area within the Building actually
occupied: cleaning, management, and energy expenses. Landlord and Tenant
acknowledge and agree that the rentable square footage of the Building is
85,232.

     B.   Landlord shall, each year during the Term of this Lease Agreement,
give Tenant an estimate of Operating Expenses and Real Estate Taxes payable per
square foot of rentable area for the coming calendar year. Tenant shall pay, as
Additional Rental, along with its monthly Minimum Rental payments required
hereunder, one-twelfth (1/12) of such estimated Operating Expenses and Real
Estate Taxes and such Additional Rental shall be payable until subsequently
adjusted for the following year pursuant to this Article.

     C.   As soon as possible after the expiration of each calendar year,
Landlord shall determine and certify to Tenant the actual Operating Expenses and
Real Estate Taxes for the previous year per square foot of rentable area in the
Building and the amount applicable to the Premises.  If such statement shows
that Tenant's share of Operating Expenses and Real Estate Taxes exceeds Tenant's
estimated monthly payments for the previous calendar year, then Tenant shall,
within twenty (20) days after receiving Landlord's certification, pay such
deficiency to Landlord.  In the event of an overpayment by Tenant, such
overpayment shall be refunded to Tenant, at the time of certification, in the
form of an adjustment in the Additional Rental next coming due, or if at the end
of the Term by a refund.  Tenant or its representatives shall have the right to
examine Landlord's books and records of Operating Expenses, for the immediately
preceding year only, during normal business hours within sixty (60) days
following the furnishing of the summary to Tenant.  Unless Tenant takes written
exception to any item within ninety (90) days following the furnishing of the
summary to Tenant (which item shall be paid in any event), such summary shall be
considered as final and accepted by Tenant.

     D.   For the purposes of this Article, the term "Real Estate Taxes" means
the total of all taxes, fees, charges and assessments, general and special,
ordinary and extraordinary, foreseen or unforeseen, which become due or payable
upon the Building during the Term. All third-party costs and expenses incurred
by Landlord during negotiations for or contests of the amount of Real Estate
Taxes shall be included within the term "Real Estate Taxes." As used in this
Lease, the term "Operating Expenses" shall mean any and all expenses, costs and

calendar year (regardless of when such Operating Expenses were incurred).
Operating Expenses shall include, without limitation, the costs of maintenance,
repairs and replacements to the Building, including, without limitation,
downspouts, gutters, painting, sprinkler systems, roof and walls, interior and

Property allocable to the Property; insurance costs, all heating and air
conditioning costs, electricity, sewer and water and other utility costs not
separately metered to tenants, landscape maintenance, trash and snow removal,
Real Estate Taxes, as defined in this Article 6(D), and costs and expenses

costs of alterations of any tenant's premises, including the Premises; (ii)
costs of curing construction defects to the base Building; (iii) depreciation;
(iv) interest and principal payments on mortgages, and other debt costs; (v)
real estate brokers' leasing commissions or compensation or marketing and
promotional costs to lease or sell the Property; (vi) any cost or expenditure
(or portion thereof) for which Landlord is reimbursed, whether by insurance
proceeds or otherwise; (vii) cost of any service furnished to any other occupant
of the Building which Landlord does not provide to Tenant hereunder; and(viii)
the full replacement of (A) roofs, (B) exterior walls; provided however that the
term "exterior walls" as used in this Lease shall not include windows, glass or

to reduce Operating Costs; or (B) which are required under any governmental
laws, regulations, or ordinances which were not applicable to the Building at
the time it was constructed, including, without limitation, the Americans With
Disabilities Act of 1990, as amended (the "ADA"), shall be included in Operating
Costs; provided however that Landlord shall capitalize capital improvements to
the extent Landlord would be required to do so pursuant to generally accepted
accounting principles in use in the real estate industry on the date of the
installation of such improvement. The cost of said improvement, structural
repair or replacement or shall be amortized over the useful life of said
improvement as reasonably determined by Landlord and in use in the real estate
industry on the date of the installation of such improvement, which amortization
shall be based upon equal payments of principal and interest over said useful
life, and interest shall be at the rate of twelve percent (12%) per annum.
Throughout that portion of the Term during which such amortization occurs,
Tenant shall pay, as a part of Operating Expenses, its Proportionate Share of
such amortization, including interest as specified above.

     E.   Landlord may at any time designate a fiscal year in lieu of a calendar
year and in such event, at the time of such a change, there may be a billing for
the fiscal year which is less than 12 calendar months, so long as no "overlap"
or double counting occurs.
<PAGE>

     F.   Landlord reserves, and Tenant hereby assigns to Landlord, the sole and
exclusive right to contest, protest, petition for review, or otherwise seek a
reduction in the Real Estate Taxes.

ARTICLE 7 - UTILITIES AND SERVICE

     A.   Landlord agrees to furnish heating, ventilation, air-conditioning,
water, electricity, elevator service and janitorial service. In the event
Tenant's requirements and/or usage of such utilities and services is
substantially greater on a square footage basis than is customarily supplied to
a typical tenant in the Building, Landlord or Tenant may request that the
difference in such requirement and/or usage be determined, at Tenant's cost, and
that appropriate adjustments be made in the Minimum Rental provided for in
Article 3 of this Lease Agreement.

     B.   Landlord shall not be liable for any interruption or failure of
utility services, communications or data services serving the Building or the
Premises arising from any cause whatsoever.  Notwithstanding the foregoing,
Landlord and Tenant agree that if the failure or interruption of said utility
services, communications or data services is a result of the action or inaction
of Landlord, or otherwise within the control of Landlord, and if the ability to
restore the same is within Landlord's control, and the interrupted or failed
utility service, communication or data service is not restored within three (3)
business days after notice from Tenant of the failure or interruption of such
utility service, communication or data service, Base Rent shall abate to the
extent the Premises are untenantable, which abatement shall commence from and
after the third day after Landlord's receipt of Tenant's notice of the
interruption or failure, and which abatement shall constitute Tenant's sole
remedy for the interruption or failure of such utility services, data or
communication services.  Nothing in this Article 7.B. shall be deemed to modify
the obligations of the parties pursuant to Article 16 hereof.

     C.   For the purposes of this Article 7, normal business hours shall be
deemed to mean the period of time between 8:00 a.m. and 5:00 p.m., Monday

limitation, damage to or failure to provide heat, electricity, air-conditioning,
elevator service, water, sprinklering or janitorial service) other than
Landlord's gross negligence or willful misconduct.  Landlord shall not be liable

     design, artwork and color scheme.

     B.   If Tenant shall fail to keep and preserve the Premises in the state of
condition required by the provisions of this Article 9, Landlord upon ten (10)
days prior written notice to Tenant, except in an emergency, when no notice

event of am emergency, when no notice shall be required, for the purpose of
exhibiting the Premises to prospective purchasers or lenders, inspection,
cleaning, repairing, testing, altering or improving the same or said Building,

obligation on Landlord to make any repairs, alterations or improvements. In
addition to the foregoing, during the period that is nine (9) months prior to
the end of the Term, Landlord shall have the right to enter the Premises at any
reasonable time for the purpose of showing the Premises to prospective tenants

withheld or delayed, if such alterations, repairs, additions or improvements are
required of Tenant or are the obligation of Tenant pursuant to this Lease
Agreement. All such work shall comply with all applicable governmental laws,
ordinances, rules and regulations. Landlord as a condition to said consent may
require a surety performance and/or payment bond from Tenant for said actions.
Tenant agrees to indemnify and hold Landlord free and harmless from any
liability, loss, cost, damage or expense (including attorney's fees) by reasons
of any said alteration, repairs, additions or improvements.

ARTICLE 13 - SIGNS

     Tenant agrees that no signs or other advertising materials shall be

ARTICLE 14 - COMMON AREAS

     A.   Tenant agrees that the use of all corridors, passageways, elevators,
toilet rooms, parking areas and landscaped area in and around said Building, by
Tenant or Tenant's employees, visitors or invitees, shall be subject to such
non-discriminatory rules and regulations as may from time to time be made by
Landlord for the safety, comfort and convenience of the owners, occupants,
tenants and invitees of said Building. Tenant agrees that no awnings, curtains,
drapes or shades shall be used upon the Premises except as may be approved by

     B.   In addition to the Premises, Tenant shall have the right of non-

             -----------
Landlord also reserves all airspace rights above, below and to all sides of the
Premises and the Building, including the right to make changes, alterations or
provide additional leasing areas.   Notwithstanding the foregoing, Landlord
agrees that the exercise of its rights hereunder will have no material adverse
effects on Tenant's use of or access to the Premises.

or agency with jurisdiction, that the Common Areas are in violation of the ADA.

ARTICLE 15 - ASSIGNMENT AND SUBLETTING

     A.   Tenant shall not have the right to assign or pledge this Lease or to
sublet the whole or any part of the Premises, whether voluntarily or by
operation of law, or permit the use or occupancy of the Premises by anyone other
than Tenant, without the prior written consent of Landlord, and such
restrictions shall be binding upon any assignee or subtenant to which Landlord
has consented.  The foregoing prohibition includes, without limitation, any
subletting or assignment which would otherwise occur by merger, consolidation,
reorganization, transfer or other change in Tenant's corporate, partnership or
proprietary structure.  Notwithstanding any permitted assignment or subletting,
Tenant shall at all times remain directly, primarily and fully responsible and
liable for the payment of Minimum Rental, Additional Rental, Operating Expenses
and Real Estate Taxes and for compliance with all of its other obligations under
the terms, provisions and covenants of this Lease. Upon the occurrence of an
Event of Default, if the Premises or any part thereof are then assigned or
sublet, Landlord, in addition to any other remedies herein provided or provided
by law, may, at its option, collect directly from any assignee or subtenant all
amounts due and becoming due to Tenant under such assignment or sublease and
apply such amounts against any sums due to Landlord from Tenant hereunder, and
no such collection shall be construed to constitute a novation or release of
Tenant from the further performance of Tenant's obligations hereunder.
Landlord's acceptance of any Minimum Rental, Additional Rental, Operating
Expenses and Real Estate Taxes following any assignment  or other transfer
prohibited by this Article 15 shall not be deemed to be a consent by Landlord to
such assignment or other transfer (including, without limitation, a prohibited
sublease) nor shall the same be deemed a waiver of any right or remedy of
Landlord hereunder for breach of this Article 15.

     If Landlord grants its consent to any sublease or assignment, Tenant shall
pay Landlord, as Additional Rental, and in addition to the Minimum Rental
payable hereunder (a) fifty percent (50%) of rent payable to Tenant by the
assignee or sublessee if such rent exceeds the Minimum Rental payable hereunder,
it being understood and agreed that Tenant shall pay all costs associated with
such sublease or assignment, including, without limitation, leasehold
improvement costs, brokerage commissions and its own legal fees and costs; and
(b) Landlord's attorneys' fees incurred with respect to such assignment or
sublease. In addition, if Tenant has any options to extend or renew the Term,
such options shall not be available to any subtenant directly or indirectly. If
Tenant assigns this Lease or sublets all or a portion of the Premises without
first obtaining Landlord's consent, as required by this Paragraph 15.A, said
assignment or sublease shall be null and void and of no force or effect.
Landlord's consent to an assignment, sublease or other transfer of any interest
of Tenant in this Lease or in the Premises shall not be deemed to be a consent
to any subsequent assignment, transfer, use or occupation.

     Tenant shall, at Tenant's own cost and expense, discharge in full any
outstanding commission obligation on the part of Landlord with respect to this
Lease, and any commissions which may be due and owing as a result of any
proposed assignment or subletting, whether or not the Premises are recaptured
pursuant to subparagraph B. below and rented by Landlord to the proposed tenant
or any other tenant.

     B.   In addition, but not in limitation of, Landlord's right to approve of
any subtenant or assignee, Landlord shall have the option, in its sole
discretion, in the event of any proposed subletting or assignment, to terminate
this Lease, or in the case of a proposed subletting of less than the entire
Premises, to recapture the portion of the Premises to be sublet, as of the date
the subletting or assignment is to be effective. The option shall be exercised,
if at all, by Landlord giving Tenant written notice thereof within thirty (30)
days following Landlord's receipt of Tenant's written notice as required above.
If this Lease shall be terminated with respect to the entire Premises pursuant
to this subparagraph, the Term shall end on the date stated in Tenant's notice
as the effective date of the sublease or assignment as if that date had been the
expiration date of the Term. If Landlord recaptures only a portion of the
Premises under this subparagraph, the Minimum Rental, Real Estate Taxes and
Operating Expenses during the remainder of the Term shall abate proportionately
based on the Minimum Rental payable hereunder as of the date immediately prior
to such recapture.

     C.   Provided Tenant is not then in default under this Lease, and
notwithstanding the prohibition on assignment and subleasing described in
Article 15.A. hereof, Tenant shall have the right to assign this Lease (but not
to sublease all or a portion of the Premises) to an entity which is the
purchaser of all or substantially all of the ownership interests in Tenant or
all or substantially all of the assets of Tenant, whether by merger,
consolidation or otherwise upon Tenant's compliance with the following
conditions:

     (i)   Tenant notifies Landlord, in writing (the "Transfer Notice"), of such
           assignment or sublease at least thirty (30) days prior to the date of
           such assignment and provides therewith copies of the proposed
           assignment documents;

     (ii)  the Transfer Notice shall be accompanied by a writing satisfactory to
           Landlord, in Landlord's sole discretion, whereby the purchaser
           assumes and agrees to perform the Lease and Tenant's obligations
           hereunder;
<PAGE>

     (iii)  simultaneously with the delivery of the Transfer Notice, Tenant
            provides Landlord with financial statements satisfactory to Landlord
            in Landlord's sole discretion, which show that the purchaser, after
            completion of the transaction contemplated by the assignment and
            assumption documents, will have a net worth equal to the greater of:

            (A)   Tenant's net worth as of the date of this Lease; or

            (B)   net worth of at least the required net worth of tenants to
                  whom Landlord is then in the process of leasing similar square
                  footage in the Project, it being understood and agreed that if
                  Landlord is then requiring new tenants of such similar spaces
                  to enhance their credit by virtue of security deposits,
                  letters of credit or similar vehicles, Landlord may require
                  that the purchaser comply with such credit enhancement
                  requirements;

     (iv)   simultaneously with Tenant's delivery of the Transfer Notice, Tenant
            shall pay Landlord's costs and expenses with respect to the
            transfer, including, without limitation, costs incurred in
            connection with the review of financial materials, meeting with
            representatives of transferor and/or transferee and preparation,
            review, approval and execution of the required transfer
            documentation, including attorneys' fees and costs, incurred by
            Landlord with respect to such transfer;

     (v)    any guarantor of Tenant's obligations under this Lease shall
            continue to remain liable under its guaranty, and, Tenant shall
            cause such guarantor to execute such documents as Landlord deems
            necessary for the confirmation by such guarantor of its guaranty;

     (vi)   there shall be no change in the Use of the Premises by the
            purchaser; and

     (vii)  the purchaser is not a tenant of Landlord in the Project or a
            prospective tenant of the Project then working with Landlord or
            Landlord's leasing agent.

Tenant's assignment of this Lease without first complying with the provisions of
this Article 15.C. shall constitute an Event of Default under this Lease, and
shall entitle Landlord to the exercise of all of its rights and remedies
hereunder, at law or in equity. In addition, said assignment or sublease shall
be null and void and of no force or effect. Landlord's consent to an assignment
of this Lease shall not be deemed to be a consent to any subsequent assignment,
transfer, use or occupation. The right granted by this Article 15.C. shall be
personal to Tenant and shall not be available to any assignee or other
transferee of Tenant's interest in this Lease or the Premises.

It is understood and agreed that all of the terms and provisions of any
documents or other material submitted to Landlord pursuant to this Article 15.C.
shall be held in confidence and shall not be disclosed to any person, firm or
entity, except: (1) pursuant to any valid order of a court of competent
jurisdiction obtained by any party other than Landlord or Tenant respecting such
material; or (2) as may be necessary in any litigation seeking enforcement of or
damages for breach of this Article 15.C; or (3) to the extent such material is
or becomes public knowledge. In the event disclosure is compelled as specified
herein, the disclosing party shall provide at least ten (10) days' prior written
notice to the other party, prior to the disclosure, of the identity of the third
party to which disclosure is to be made.

ARTICLE 16 - LOSS BY CASUALTY

     If the Building should be damaged or destroyed by fire, tornado or other
casualty, Tenant shall give prompt oral and written notice thereof to Landlord's
Managing Agent. If the Building should be:

     (a)    destroyed by fire, tornado or other casualty, or

     (b)    so damaged that rebuilding or repairs cannot in Landlord's
            estimation be completed within two hundred (200) days after the
            effective date of Tenant's notice to Landlord of such damage,

this Lease shall terminate and Minimum Rental, Real Estate Taxes and Operating
Expenses shall be abated during the unexpired portion of this Lease, effective
upon the date of the occurrence of such damage, and from and after such
termination, neither Landlord nor Tenant shall be liable to the other for any
damages, costs or expenses of any kind or nature accruing after the date of the
damage or destruction. Notwithstanding the foregoing, if the Building should be
damaged to any extent at any time during the last twelve (12) calendar months of
the term, and if, as of the date of the casualty:

     (j)    Tenant then does not have the right to exercise the option to renew
            granted by Article 39 hereof, then this Lease shall terminate and
            Minimum Rental, Real Estate Taxes and Operating Expenses shall be
            abated during the unexpired portion of this Lease, effective upon
            the date of the occurrence of such damage, and from and after
<PAGE>

            such termination, neither Landlord nor Tenant shall be liable to the
            other for any damages, costs or expenses of any kind or nature
            accruing after the date of the damage or destruction; or

     (k)     Tenant either (i) has exercised the option to renew granted by
             Article 39 hereof; or (ii) has the right to exercise the option to
             renew granted by Article 39 hereof and exercises such option within
             the time period therefor set forth in said Article 39, then
             Landlord shall be obligated to repair or rebuild so long as the
             Building has neither (i) been destroyed; nor (ii) so damaged that
             rebuilding or repairs cannot, in Landlord's estimation, be
             completed within two hundred (200) days after the effective date of
             Tenant's notice to Landlord of such damage.

     Subject to the preceding paragraph, if the Building should be damaged by
any peril, to such extent that rebuilding or repairs can, in Landlord's
estimation, be completed within two hundred (200) days after the effective date
of Tenant's notice to Landlord of such damage, this Lease shall not terminate,
and Landlord shall, at its sole cost and expense, proceed with reasonable
diligence to rebuild and repair the Building to substantially the condition in
which it existed prior to such damage, except that Landlord shall not be
required to rebuild, repair or replace any part of the partitions, fixtures,
additions and other improvements which may have been placed in, on or about the
Premises by Tenant. If the Premises are untenantable in whole or in part
following such damage, Minimum Rental and Operating Expenses payable hereunder
during the period in which the Premises are untenantable shall be reduced to
such extent as may be fair and reasonable under all of the circumstances. In the
event that Landlord should fail to complete such repairs and rebuilding within
two hundred (200) days after the effective date of Tenant's notice to Landlord
of the damage (unless any such delay is due to changes, deletions or additions
in construction requested by Tenant, strikes, lockouts, casualties, force
majeure, war, material or labor shortages, governmental regulation or control or
other causes beyond the reasonable control of Landlord, in which event such
period shall be extended for the amount of time Landlord is so delayed), Tenant,
at its option, and as its sole remedy, may terminate this Lease by written
notice given to Landlord by the two hundred tenth (210th) day after the
effective date of Tenant's notice to Landlord of the damage, it being understood
and agreed that if such notice of termination is not given as of said two
hundred tenth (210th) day, Tenant shall be deemed to have waived its right to
terminate pursuant to this Article, this Lease will continue of full force and
effect and the repairs shall be completed as soon as reasonably possible.

ARTICLE 17 - WAIVER OF SUBROGATION

     Except as provided below, each of Landlord and Tenant agrees to rely
entirely upon its own property insurance with respect to any damage, loss or
injury to its property.

     Each of Landlord and Tenant hereby releases the other and the other party's
directors, officers, employees, agents and others acting on the other party's
behalf (collectively, the "released parties") from all claims and all liability
or responsibility to the releasing party and to any person claiming through or
under the releasing party, by way of subrogation or otherwise, for any loss or
damage to the releasing party's business or property caused by fire or other
peril, even if such fire or other peril was caused in whole or in part by the
negligence or other act or omission of one or more of the released parties.
Notwithstanding the foregoing, the release from liability and waiver or
subrogation provided for shall (i) only be effective to the extent that the loss
or damage to the releasing party's business or property is actually covered by
insurance; and (ii) not apply to the extent of any deductible (or deductibles)
applying under such insurance.

ARTICLE 18 - EMINENT DOMAIN

     If the entire Building is taken by eminent domain, this Lease Agreement
shall automatically terminate as of the date of taking. If a portion of the
Building is taken by eminent domain, Landlord shall have the right to terminate
this Lease Agreement, provided it gives written notice thereof to Tenant within
ninety (90) days after the date of taking. If a portion of the Premises is taken
by eminent domain and this Lease Agreement is not terminated by Landlord,
Landlord shall, at its expense, restore the Premises to as near the condition
which existed immediately prior to the date of taking as reasonably possible,
and the rentals shall abate during such period of time as the Premises are
untenantable, in the proportion that the untenantable portion of the Premises
bears to the entire Premises. All damages awarded for such taking under the
power of eminent domain shall belong to and be the sole property of Landlord,
irrespective of the basis upon which they are awarded, provided, however, that
nothing contained herein shall prevent Tenant from making a separate claim to
the condemning authority for its moving expenses and trade fixtures. For
purposes of this Article, a taking by eminent domain shall include Landlord's
giving of a deed under threat of condemnation.

ARTICLE 19 - SURRENDER

     On the last day of the Term of this Lease Agreement or on the sooner
termination thereof in accordance with the terms hereof, Tenant shall peaceably
surrender the Premises in good condition and repair consistent with Tenant's
duty to make repairs as provided in Article 9 hereof. On or before said last
day, Tenant shall at its expense remove all of its equipment from the Premises,
repairing any damage caused thereby, and any property not removed shall be
deemed abandoned. All alterations, additions and fixtures other than Tenant's
trade fixtures, which have been made or installed by either Landlord or Tenant
upon the Premises shall remain as Landlord's property and shall be surrendered
with the Premises as a part thereof, or shall be removed by Tenant, at the
option of Landlord, in which event Tenant shall at its expense repair any damage
caused thereby; provided however that Tenant shall not be obligated to remove
the improvements to be constructed in the Premises pursuant to Exhibit B hereof,
                                                               ---------
or any subsequent alterations, additions or fixtures which Landlord has agreed,
in writing, as of the date of the installation of such alteration, addition
<PAGE>

or fixture, need not be removed. It is specifically agreed that any and all
telephonic (including, without limitation, phone board), coaxial, ethernet, or
other computer, word processing, facsimile, or electronic wiring installed by
Tenant within the Premises or the Building (hereafter "Wiring") shall be removed
at Tenant's cost at the expiration of the Term, unless Landlord has specifically
requested in writing that said Wiring shall remain, whereupon said Wiring shall
be surrendered with the Premises as Landlord's property. If the Premises are not
surrendered at the end of the Term or the sooner termination thereof, Tenant
shall indemnify Landlord against loss or liability resulting from delay by
Tenant in so surrendering the Premises, including, without limitation, claims
made by any succeeding tenant founded on such delay. Tenant shall promptly
surrender all keys for the Premises to Landlord at the place then fixed for
payment of rental and shall inform Landlord of combinations on any locks and
safes on the Premises.

ARTICLE 20 - NON-PAYMENT OF RENT, DEFAULTS

     A.    Each of the following events shall be deemed to be an Event of
           Default by Tenant under this Lease:

     i.    Tenant shall fail to pay any installment or other payment of Minimum
           Rental, Real Estate Taxes, Operating Expenses or any other amount
           payable by Tenant hereunder (collectively, "Rent") when due, and such
           failure shall continue for a period of five (5) days from the date
           such payment was due, except that Landlord agrees to give written
           notice of non-payment of Rent once in each calendar year of the term
           (but not any renewal term), in which case, there shall be no Event of
           Default unless Rent then payable has not been paid within five (5)
           days after the effective date of Landlord's written notice of non-
           payment;

     ii.   Tenant shall become insolvent, or shall make a transfer in fraud of
           creditors, or shall make an assignment for the benefit of creditors;

     iii.  Tenant shall file a petition under any section or chapter of the
           federal bankruptcy laws, or under any similar law or statute of the
           United States or any State, including, without limitation, a
           liquidation, rehabilitation or other insolvency statute, whether now
           or hereafter in effect; or an order for relief shall be entered
           against Tenant in any such bankruptcy or insolvency proceedings filed
           against Tenant thereunder or Tenant shall be adjudged bankrupt or
           insolvent in proceedings filed against Tenant thereunder;

     iv.   A receiver or trustee shall be appointed for all or substantially all
           of the assets of Tenant;

     v.    Tenant shall generally not pay its debts as such debts become due;

     vi.   Tenant shall fail to discharge any lien placed upon the Premises in
           violation of Article 27 hereof;

     vii.  Tenant shall fail to insure and provide evidence of such insurance in
           accordance with Article 24 hereof within five (5) days after the
           effective date of written notice from Landlord; or

     viii. Tenant shall fail to comply with any term, provision or covenant of
           this Lease (other than the foregoing in this Article 20), and shall
           not cure such failure within twenty (20) days after written notice
           thereof from Landlord to Tenant; provided however, that Tenant shall
           not be in default under this Lease so long as Tenant commences to
           cure such default within ten (10) days after notice thereof from
           Landlord and completes such cure within sixty (60) days after notice
           thereof from Landlord..

     B.    Upon the occurrence of any one or more of such events of default
described in Article 20 hereof, Landlord shall have the option to pursue any one
or more of the following remedies without any further notice or demand
whatsoever.

     i.    Landlord may, at its election, terminate this Lease or terminate
           Tenant's right to possession only, without terminating the Lease;

     ii.   Upon any termination of this Lease, whether by lapse of time or
           otherwise, or upon any termination of Tenant's right to possession
           without termination of this Lease, Tenant shall surrender possession
           and vacate the Premises immediately and deliver possession thereof to
           Landlord, and Tenant hereby grants to Landlord full and free license
           to enter into and upon the Premises in such event with or without
           process of law and to repossess Landlord of the Premises as of
           Landlord's former estate and to expel or remove Tenant and any others
           who may be occupying or within the Premises and to alter all locks
           and other security devices at the Premises and to remove any and all
           property therefrom, without being deemed in any manner guilty of
           trespass, eviction or forcible entry or detainer, and without
           incurring any liability for any damage resulting therefrom. Tenant
           hereby waives any right to claim damage for such re-entry and
           expulsion, and such entry and possession shall not terminate this
           Lease or release Tenant, in whole or in part, from any obligation,
           including Tenant's obligation to pay all Minimum Rental, Additional
           Rental, Operating Expenses and Real Estate Taxes payable by Tenant
           hereunder, for the Term or any other right given to Landlord
           hereunder or by operation of law;
<PAGE>

     iii. Landlord may, but need not, relet the Premises or any part thereof for
          such Minimum Rental and upon such terms as Landlord, in its sole
          discretion, shall determine (including the right to relet the Premises
          as part of a larger area and the right to change the character or the
          use made of the Premises), and Landlord shall not be required to
          accept any tenant offered by Tenant or to observe any instructions
          given by Tenant about such reletting. In any such case, Landlord may
          make repairs, alterations and additions in or to the Premises, and
          redecorate the same to the extent Landlord deems necessary or
          desirable, in its sole discretion. All Minimum Rental, Additional
          Rental, Operating Expenses, Real Estate Taxes and other sums received
          by Landlord from any such reletting shall be applied as follows:
          first, to the payment of any indebtedness other than Minimum Rental,
          Additional Rental, Operating Expenses and Real Estate Taxes due
          hereunder from Tenant to Landlord; second, to the payment of any costs
          and expenses of such alterations and repairs; third, to the payment of
          Landlord's expenses of reletting, including, without limitation,
          broker's commissions, reasonable attorney fees and lease inducements,
          such as moving or leasehold improvement allowances; fourth, to the
          payment of Minimum Rental, Additional Rental, Operating Expenses and
          Real Estate Taxes due and unpaid hereunder; and the residue, if any,
          shall be held by Landlord and applied in payment of future Minimum
          Rental, Additional Rental, Operating Expenses and Real Estate Taxes as
          the same may become due and payable hereunder. If such Minimum Rental,
          Additional Rental, Operating Expenses and Real Estate Taxes and other
          sums received from such reletting during any month be less than the
          Minimum Rental, Additional Rental, Operating Expenses and Real Estate
          Taxes to be paid during said month by Tenant hereunder, Tenant shall
          pay such deficiency to Landlord. Such deficiency shall be calculated
          and paid monthly. Notwithstanding any such re-entry by Landlord,
          Landlord may at any time hereafter elect to terminate this Lease for
          such previous breach.

     iv.  Tenant acknowledges that the damages Landlord would incur in
          connection with terminating this Lease following a default by Tenant
          would be difficult to estimate or ascertain. Therefore, Tenant agrees
          that, in the event Landlord elects to terminate this Lease, Landlord
          may, in addition to other remedies available at law or in equity,
          accelerate the remaining Rent obligations of Tenant under this Lease,
          declaring all such amounts immediately due and payable, in which case,
          as Landlord' sole remedy, Landlord may recover from Tenant, as
          liquidated damages, and not as a penalty, an amount equal to the sum
          of the following: (A) all unpaid Minimum Rental, Additional Rental,
          Operating Expenses and Real Estate Taxes that is payable by Tenant
          hereunder and that accrues through the effective date of termination;
          plus (B) the cost of repairs, alterations and/or redecoration of the
          Premises that Landlord determines are necessary, in Landlord's sole
          discretion; plus (C) a sum of money equal to the entire amount of
          Minimum Rental, Additional Rental, Operating Expenses and Real Estate
          Taxes that would be payable under the Lease for the lesser of (1) the
          three (3) year period commencing upon the effective date of
          termination, or (2) the period commencing upon the effective date of
          termination and ending upon the original date of the expiration of the
          Term, which amount shall be immediately due and payable upon demand,
          but which amount shall be discounted to present value using a discount
          rate equal to the discount rate of the Federal Reserve Bank of
          Minneapolis as of the date of termination plus one percent (1%); plus
          (D) to the extent not included in the calculation of Minimum Rental,
          Additional Rental, Operating Expenses and Real Estate Taxes payable
          pursuant to subparagraph (B) above, a sum of money equal to the
          remaining principal balance of the original cost of any leasing
          commissions and leasehold improvements in the Premises paid for by
          Landlord on the effective date of termination, together with interest
          at a rate of twelve percent (12%) per annum amortized over the entire
          Term, assuming amortization based upon equal monthly payments of
          principal and interest. For purposes of calculating the amount of
          Minimum Rental, Additional Rental, Operating Expenses and Real Estate
          Taxes that would be payable under the Lease for the period succeeding
          the effective date of termination, such Minimum Rental, Additional
          Rental, Operating Expenses and Real Estate Taxes shall be computed on
          the basis of the average monthly amount of Minimum Rental, Additional
          Rental, Operating Expenses and Real Estate Taxes accruing during the
          twenty-four (24) month period immediately preceding the default to
          which such termination relates (exclusive of any months in which
          Tenant received "free" or abated Minimum Rental or Operating Expense
          concessions); provided, however, if the default occurs prior to the
          expiration of the first twenty-four (24) months of the Lease, then the
          Minimum Rental, Additional Rental, Operating Expenses and Real Estate
          Taxes shall be computed on the basis of the average monthly amount of
          Minimum Rental, Additional Rental, Operating Expenses and Real Estate
          Taxes accruing during all months preceding the month in which said
          default occurred (exclusive of any months in which Tenant received
          "free" or abated Minimum Rental or Operating Expense concessions).

     v.   Any and all property which may be removed from the Premises by
          Landlord pursuant to the authority of the Lease or of law, to which
          Tenant is or may be entitled, may be handled, removed and stored, as
          the case may be, by or at the direction of Landlord at the risk, cost
          and expense of Tenant, and Landlord shall in no event be responsible
          for the value, preservation or safekeeping thereof. Tenant shall pay
          to Landlord, upon demand, any and all expenses incurred in such
          removal and all storage charges against such property so long as the
          same shall be in Landlord's possession or under Landlord's control.
          Any such property of Tenant not retaken by Tenant
<PAGE>

          from storage within thirty (30) days after removal from the Premises
          shall, at Landlord's option, be deemed conveyed by Tenant to Landlord
          under this Lease as by a bill of sale without further payment or
          credit by Landlord to Tenant.

     Pursuit of any of the foregoing remedies shall not preclude pursuit of any
of the other remedies herein provided or any other remedies provided by law, nor
shall pursuit of any remedy herein provided constitute a forfeiture or waiver of
any Minimum Rental, Additional Rental, Operating Expenses or Real Estate Taxes
due to Landlord hereunder or of any damages accruing to Landlord by reason of
the violation of any of the terms, provisions and covenants herein contained. No
act or thing done by Landlord or its agents during the Term shall be deemed a
termination of this Lease or an acceptance of the surrender of the Premises, and
no agreement to terminate this Lease or accept a surrender of said Premises
shall be valid unless in writing signed by Landlord. No waiver by Landlord of
any violation or breach of any of the terms, provisions and covenants herein
contained shall be deemed or construed to constitute a waiver of any other
violation or breach of any of the terms, provisions and covenants herein
contained. Landlord's acceptance of the payment of Minimum Rental, Additional
Rental, Operating Expenses or Real Estate Taxes or other payments hereunder
after the occurrence of an event of default shall not be construed as a waiver
of such default, unless Landlord so notifies Tenant in writing. Forbearance by
Landlord to enforce one or more of the remedies herein provided upon an event of
default shall not be deemed or construed to constitute a waiver of such default
or of Landlord's right to enforce any such remedies with respect to such default
or any subsequent default.

ARTICLE 21 - LANDLORD'S DEFAULT

     Landlord shall not be deemed to be in default under this Lease Agreement
until Tenant has given Landlord written notice specifying the nature of the
default and Landlord does not cure such default within thirty (30) days after
receipt of such notice or within such reasonable time thereafter as may be
necessary to cure such default where such default is of such a character as to
reasonably require more than thirty (30) days to cure.

ARTICLE 22 - HOLDING OVER

     Tenant will, at the termination of this Lease by lapse of time or
otherwise, yield up immediate possession to Landlord. If Tenant retains
possession of the Premises or any part thereof after such termination, then,
subject to the last sentence of this Article, such holding over shall constitute
creation of a month to month tenancy, upon the terms and conditions of this
Lease; provided, however, that the monthly rental for such holding over shall,
in addition to all other sums which are to be paid by Tenant hereunder, whether
or not as Additional Rental, be equal to one hundred fifty percent (150%) of the
Minimum Rental plus all Additional Rental, Operating Expenses and Real Estate
Taxes being paid monthly to Landlord under this Lease immediately prior to such
termination. In addition to and not in limitation of the foregoing, Tenant shall
also pay to Landlord all damages sustained by Landlord resulting from retention
of possession by Tenant, including the loss of any proposed subsequent tenant
for any portion of the Premises; provided, however, that Landlord shall make
reasonable efforts to re-lease the Premises in whole or in part; but provided
further that Landlord shall have the right to lease or attempt to lease premises
in the Building other than the Premises which, at any time, become vacant before
attempting to re-lease all or any part of the Premises pursuant to this Article.
The provisions of this Article shall not constitute a waiver by Landlord of any
right of re-entry as herein set forth; nor shall receipt of any rent or other
sums or any other act in apparent affirmance of the tenancy operate (a) as an
extension of the Term; (b) a waiver of Landlord's right to terminate Tenant's
right to possession of the Premises; or (c) a waiver of the right to terminate
this Lease for a breach of any of the terms, covenants, or obligations herein on
Tenant's part to be performed.

ARTICLE 23 - SUBORDINATION

     This Lease is and shall be subject and subordinate to any mortgage(s) now
or at any time hereafter constituting a lien or charge upon the Building or the
Premises, provided, however, that if the holder of any such mortgage elects to
have Tenant's interest in this Lease superior to any such instrument, then by
notice to Tenant from such holder, this Lease shall be deemed superior to such
lien, whether this Lease was executed before or after said mortgage. Tenant
shall at any time hereafter on demand execute any instruments, releases or other
documents which may be required by any mortgagee for the purpose of subjecting
and subordinating this Lease to the lien of any such mortgage, provided that
Tenant has received a non-disturbance agreement from Landlord's lender on such
lender's standard form. Landlord hereby represents and warrants to Tenant that,
as of the date of this Lease, there is no mortgage against the Building or the
Premises.

ARTICLE 24 - INDEMNITY, INSURANCE AND SECURITY

     A.   (1)  Tenant shall, at its sole cost and expense, maintain in effect at
all times during the Term a commercial general liability insurance policy, on an
"occurrence" rather than on a "claim made" basis, with a total combined policy
limit of at least $2,000,000.00. The policy shall include, but not be limited
to, coverages for Bodily Injury, Property Damage, Personal Injury and
Contractual Liability (applying to this Lease), or an equivalent form (or forms)
affording coverage at least as broad. Landlord and Landlord's Managing Agent
shall be named as Additional Insureds under the policy.

          (2)  Tenant shall, at its sole cost and expense, maintain in effect at
all times during the Term, a policy or polices of insurance covering all of
Tenant's improvements, fixtures, inventory and other personal property in the
Premises against loss by fire and other hazards covered by an "all-risk" form of
policy, in an amount equal to the full replacement cost thereof, without
<PAGE>

deduction for physical depreciation. Such insurance shall include Valuable
papers and Records coverage providing for the Reproduction Costs measure of
recovery and coverage for damage to Electronic Data Processing Equipment and
Media, including coverage of the perils of mechanical breakdown and electronic
disturbance.

          (3) Tenant shall, at its sole cost and expense, maintain in effect at
all times during the Term, a policy of insurance covering business interruption
for a period of at least 365 days.

          (4) If the use of the Premises by Tenant increases the premium rate
for insurance carried by Landlord on the Building, Tenant shall pay Landlord,
upon demand, as Additional Rental, the amount of such premium increase.

          (5) Tenant, upon actual knowledge or receipt of written notice by
Landlord, shall not carry any stock of goods, inventory, or Hazardous Substances
(as defined in this Lease) or do anything in or about the Premises which will in
any way impair or invalidate the obligation of the insurer under any policy of
insurance required by this Lease.

          (6) Insurance policies required by this Article 24 shall be in a form
reasonably acceptable to Landlord, with an insurer or insurers having a Best
rating of A-X or better and qualified to do business in the State of Minnesota,
and shall require at least thirty (30) days prior written notice to Landlord
(and, if requested by Landlord, Landlord's mortgagee(s)), of termination,
cancellation, non-renewal or material alteration.  The liability insurance under
subparagraph A. shall be primary with respect to Landlord and its agents and not
participating with any other available insurance.

Prior to the Commencement Date, on each anniversary of the Commencement Date and
at such other times as Landlord may request, Tenant shall deliver to Landlord a
certificate evidencing such policies, or other evidence reasonably satisfactory
to Landlord, confirming (i) the terms of the insurance, (ii) that the premiums
have been paid at least one (1) year in advance, and (iii) that the policies are
in full force and effect.  If Tenant has a blanket insurance policy providing
coverage for several properties of Tenant, including the Premises, Landlord will
accept a certificate of such insurance, provided:

     (1)  the certificate states the amounts of insurance and types of coverage;
     (2)  the amounts are at least equal to the amounts that would be required
in this Lease; and
     (3)  the policy complies with the other requirements in this Lease.

     B.   Tenant shall be responsible for the security and safeguarding of the
Premises and all property kept, stored or maintained in the Premises. Tenant
represents that it is satisfied that the construction of the Building and the
Premises, including the floors, walls, windows, doors and means of access
thereto are suitable for the particular needs of Tenant's business. Tenant shall
maintain in force throughout the Term, insurance upon all contents of the
Premises, including that owned by others and Tenant's equipment and any
alterations, additions, fixtures, or improvements in the Premises acknowledged
by Landlord to be Tenant's.

     C.   Landlord shall carry and cause to be in full force and effect a fire
and extended coverage insurance policy on the Building, but not contents owned,
leased or otherwise in possession of Tenant. The cost of such insurance shall be
an Operating Expense.

ARTICLE 25 - NOTICES

     All payments, bills, statements, notices or communications, required or
desired to be given hereunder shall be in writing and shall be deemed effective
and received (a) upon personal delivery; (b) five (5) days after deposit in the
United States mail, certified mail, return receipt requested, postage prepaid;
or (c) one (1) business day after deposit with a national overnight air courier,
fees prepaid, to Landlord or Tenant, as the case may be, to the parties at the
following addresses:

ARTICLE 26 - APPLICABLE LAW

     This Lease Agreement shall be construed under the laws of the State of
Minnesota.

ARTICLE 27 - MECHANICS' LIEN

     In the event any mechanic's lien shall at any time be filed against the
Premises or any part of the Building by reason of work, labor, services or
materials performed or furnished or claimed to be performed or furnished to
Tenant or to anyone holding the Premises through or under Tenant, Tenant shall,
within thirty (30) calendar days after Tenant becomes aware of the filing of
such lien at its sole cost and expense either (a) cause such lien to be
discharged; or (b) provide security for such lien upon such terms and
conditions, including, without limitation, conditions for the release of said
security to Landlord, as Landlord, in Landlord's sole discretion, may require,
then, the same shall constitute an Event of Default hereunder; provided however,
that, in addition to any other right or remedy of Landlord, Landlord may, but
shall not be obligated to, discharge the same by paying the amount claimed to be
due, and the amount so paid by Landlord and all costs and expenses, including
reasonable attorney's fees incurred by Landlord in procuring the discharge of
such lien, shall be due and payable in full by Tenant to Landlord on demand.
Tenant hereby agrees to defend and indemnify Landlord and to hold Landlord
harmless from and against any such lien or claim or action thereon, and shall
reimburse Landlord, as Additional Rent for Landlord's costs of suit and all
attorneys' fees and costs incurred in connection with the removal of any such
lien, claim or action. Landlord hereby reserves the right, at any time and from
time to time during the construction of the Premises or any subsequent
alteration to enter onto the Premises and post and review notices in accordance
with Minn. Stat. (S)514.06, as the same may be amended.

ARTICLE 28 - SECURITY INTEREST

     Tenant hereby grants to Landlord a security interest in all goods,
chattels, fixtures and personal property belonging to Tenant, which now are or
may hereafter be placed in the Premises, to secure all rents due hereunder and
all other covenants and obligations of Tenant hereunder, which security interest
shall be subject and subordinate to all liens in the same property granted by
Tenant to one or more of its primary lenders. In the event there exists any
security interest in said property which security interest is paramount and
superior to the security interest herein created, Landlord may satisfy said
paramount security interest and all sums paid in satisfying said security
interest will be considered additional sums owed Landlord by Tenant hereunder.
Tenant hereby acknowledges receipt of a true, full and complete copy of this
Lease Agreement. Landlord, in the event of a default by Tenant of any covenant
or condition herein contained, and after the expiration of any applicable notice
and cure period, may exercise, in addition to any rights and remedies herein
granted, all the rights and remedies of a secured party under the Uniform
Commercial Code or any other applicable law. Tenant agrees upon request of
Landlord to execute and deliver to Landlord a financing statement evidencing
such security interest. A copy of this Lease Agreement may be filed as a
financing statement.

ARTICLE 29 - BROKERAGE

     Each of the parties represents and warrants that there are no claims for
brokerage commissions or finder's fees in connection with this Lease Agreement
except that Winthrop Commercial has represented Tenant and United Properties
Corporation has represented Landlord. Each party agrees to indemnify the other
against, and hold it harmless from all liabilities arising from any claim
arising from the preceding sentence, including without limitation, the cost of
attorney's fees in connection therewith.

ARTICLE 30 - INTENTIONALLY DELETED

ARTICLE 31 - ESTOPPEL CERTIFICATES

     Each party hereto agrees that at any time, and from time to time during the
Term of this Lease Agreement (but not more often than twice in each calendar

execute, acknowledge and
<PAGE>

deliver to such other party or to any prospective purchaser, assignee or
mortgagee designated by such other party, an estoppel certificate in a form
acceptable to Landlord.

ARTICLE 32 - GENERAL

     This Lease Agreement does not create the relationship of principal and
agent or of partnership or of joint venture or of any association between
Landlord and Tenant, the sole relationship between Landlord and Tenant being
that of landlord and tenant. No waiver of any default of Tenant hereunder shall
be implied from any omission by Landlord to take any action on account of such
default if such default persists or is repeated, and no express waiver shall
affect any default other than the default specified in the express waiver and
that only for the time and to the extent therein stated. The covenants of Tenant
to pay the Minimum Rental and the Additional Rental are each independent of any
other covenant, condition, or provision contained in this Lease Agreement. The
marginal or topical headings of the several Articles, paragraphs and clauses are
for convenience only and do not define, limit or construe the contents of such
Articles, paragraphs or clauses. All preliminary negotiations are merged into
and incorporated in this Lease Agreement. This Lease Agreement can only be
modified or amended by an agreement in writing signed by the parties hereto. All
provisions hereof shall be binding upon the heirs, successors and assigns of
each party hereto. If any term or provision of this Lease Agreement shall to any
extent be held invalid or unenforceable, the remainder shall not be affected
thereby, and each other term and provision of this Lease Agreement shall be
valid and be enforced to the fullest extent permitted by law. If Tenant is a
corporation, each individual executing this Lease Agreement on behalf of said
corporation represents and warrants that he is duly authorized to execute and
deliver this Lease Agreement on behalf of said corporation in accordance with a
duly adopted resolution of the Board of Directors of said corporation or in
accordance with the Bylaws of said corporation, and that this Lease Agreement is
binding upon said corporation in accordance with its terms. No receipt or
acceptance by Landlord from Tenant of less than the monthly rent herein
stipulated shall be deemed to be other than a partial payment on account for any
due and unpaid stipulated rent; no endorsement or statement of any check or any
letter or other writing accompanying any check or payment of rent to Landlord
shall be deemed an accord and satisfaction, and Landlord may accept and
negotiate such check or payment without prejudice to Landlord's rights to (i)
recover the remaining balance of such unpaid rent or (ii) pursue any other
remedy provided in this Lease Agreement. (Neither party shall record this Lease
Agreement or any memorandum thereof, and any such recordation shall be a breach
of this Lease Agreement void, and without effect.) Time is of the essence with
respect to the due performance of the terms, covenants and conditions herein
contained. Submission of this instrument for examination does not constitute a
reservation of or option for the Premises, and this Lease Agreement shall become
effective only upon execution and delivery thereof by Landlord and Tenant.

ARTICLE 33 - EXCULPATION

     Tenant agrees to look solely to Landlord's interest in the Building, the
proceeds of any sale thereof and, to the extent Landlord is then entitled
thereto, rents and profits arising from the leases of premises in the Building
for the recovery of any judgment from Landlord, it being agreed that Landlord
and Landlord's partners, whether general or limited (if Landlord is a
partnership) or its directors, officers or shareholders (if Landlord is a
corporation), shall never be personally liable for any such judgment. Nothing in
the preceding sentence shall be deemed to allow Tenant to set off or deduct any
amount owed to Tenant by Landlord hereunder against any payment of Rent due
under this Lease Agreement at any time.

ARTICLE 34 - SECURITY DEPOSIT

     On or before the Commencement Date, Tenant shall deposit with Landlord the
amount of one month's Minimum Rental and Operating Expenses. The Security
Deposit shall serve as a security for the prompt, full, and faithful performance
by Tenant of the terms and provisions of this Lease Agreement. In the event that
Tenant is in default hereunder and fails to cure within applicable time
permitted under this Lease Agreement, Landlord may use or apply the whole or any
part of the Security Deposit for the payment of Tenant's obligations hereunder.
The use or application of the Security Deposit or any portion thereof shall not
prevent Landlord from exercising any or other right or remedy provided hereunder
or under any Law and shall not be construed as liquidated damages. In the event
the Security Deposit is reduced by such use or application, Tenant shall deposit
with Landlord, within ten (10) days after written notice, an amount sufficient
to restore the full amount of the Security Deposit. Landlord shall not be
required to keep the Security Deposit separate from Landlord's general funds or
pay interest on the Security Deposit. Any remaining portion of the Security
Deposit shall be returned to Tenant within thirty (30) days subsequent to the
Expiration Date, as the same may be extended pursuant to Article 39 hereof.
Unless refunded in accordance with the remainder of this Article, if the
Premises shall be expanded at any time, or if the Term shall be extended at any
increased rate of Rent, the Security Deposit shall thereupon be proportionately
increased. Notwithstanding the foregoing, if no Event of Default has occurred as
of the last day of the twenty-fourth full calendar month after the Commencement
Date, Landlord shall refund the Security Deposit to Tenant, it being understood
and agreed that if an Event of Default has occurred hereunder or under the Work
Letter Agreement or any storage space or parking license entered into by
Landlord and Tenant, Landlord shall have no obligation to refund the Security
Deposit to Tenant pursuant to this sentence, but shall be otherwise obligated to
refund the Security Deposit to Tenant pursuant to the remainder of this Article
34.

ARTICLE 35 - HAZARDOUS SUBSTANCES

     Tenant shall at all times comply with all applicable local, state and
federal laws, ordinances and regulations relating to Hazardous Substances.
"Hazardous Substances" means (1) any oil, petroleum product, flammable
substances, explosives, radioactive materials, hazardous wastes or substances,

Transportation Act, as amended, 42 U.S.C." 6901, et seq.; the Federal Water
                                                 -- ---
Pollution Control Act, as amended, 33 U.S.C." 1251, et seq.; (4) any other
                                                    -- ---
chemical, material or substance, exposure to which is prohibited, limited or
regulated by any governmental authority or may or could pose a hazard to the
health and safety of the occupants of the Premises or the Building or the owners
and/or occupants of property adjacent to or surrounding the Building, or any
other person or entity coming upon the property on which the Building is located
or adjacent property; and (5) any other chemical, material or substance that may
or could pose a hazard to the environment. Tenant shall not: (i) use the
Premises or the Building for the storage of Hazardous Substances except for such
activities that are part of the course of Tenant's ordinary business (the
"Permitted Activities"); provided, such Permitted Activities are conducted in
accordance with all applicable laws, orders, regulations and ordinances and have
been approved in advance in writing by Landlord; (ii) use the Premises or the
Building as a landfill or dump; or (iii) install any underground tanks of any
type at the Building. Tenant shall at its own expense maintain in effect any and
all permits, licenses or other governmental approvals, if any, required for
Tenant's use of the Premises and require the same of any subtenants. Tenant
shall make and cause any subtenant to make all disclosures required of Tenant by
any laws, and shall comply and cause subtenant to comply with all orders
concerning Tenant's use of the Premises issued by any governmental authority
having jurisdiction over the Premises and take all action required by such
governmental authorities to bring Tenant's activities on the Premises into
compliance with all environmental and other laws, rules, regulations and
ordinances affecting the Premises. If at any time Tenant shall become aware, or
have reasonable cause to believe, that any Hazardous Substance has been released
or has otherwise come to be located on or beneath the property on which the
Building is located, Tenant shall give written notice of that condition to
Landlord immediately after Tenant becomes so aware. Tenant shall be responsible
for, and shall indemnify, defend and hold Landlord harmless from and against,
all environmental claims, demands, damages and liabilities, including, without
limitation, court costs and reasonable attorney fees, if any, arising out of, or
in connection with, the generation, storage, disposal or other presence of any
Hazardous Substance in, on or about the Premises or the Building during the Term
that Tenant or its assignees or subtenants caused or permitted. The
indemnification provided by this Article 34 shall survive the expiration or
earlier termination of this Lease.

ARTICLE 36 - EXPENSE OF ENFORCEMENT

     Tenant shall pay Landlord upon demand therefor, for all costs and
reasonable attorneys' fees and expenses incurred by Landlord in seeking
enforcement against Tenant, any assignee or sublessee of Tenant, or any
guarantor of Tenant's obligations under this Lease, of Tenant's or such party's
obligations under this Lease Agreement, including, without limitation, the
collection of Minimum Rental, Additional Rental, Operating Expenses and Real
Estate Taxes and the termination of Tenant's right to possession of the
Premises. Such payment shall constitute Additional Rent payable in accordance
with Article 3. Notwithstanding the foregoing, if Landlord commences any action
against Tenant, including, without limitation, an action in unlawful detainer,
which action settles at or prior to any trial in connection therewith, Landlord
shall be entitled to recover from Tenant Landlord's reasonable attorneys' fees
and disbursements and the same shall be payable by Tenant to Landlord with the
next installment of Minimum Rental falling due and shall constitute Additional
Rental hereunder.

ARTICLE 37 - YEAR 2000 PROBLEM

     Landlord represents that it either has or will take reasonable steps to
ensure that all computer controlled facility components of the Building are Year
2000 compliant prior to January 1, 2000. Compliance shall be verified by

ARTICLE 38 - RIGHT OF FIRST OFFER

     (a) Subordinated Space. Tenant shall have a right to lease each of Suites
         ------------------
140, 250 and the non-leased portion of Suite 250 (the Non-Leased 250 Space";
each of Suite 140, 250 and the Non-Leased 250 Space is singly, a "Subordinated
Space" and collectively, the "Subordinated Spaces") whenever the Subordinated
Space in question becomes available for lease during the Term (and the renewal
term contemplated by Article 39 hereof subject to the conditions set forth in
Article 38(c) below) in accordance with the provisions of this Article 38. For
the purposes of this Article 38, "available for lease" shall mean (I) as to
Suites 140 and 250, the tenants under leases thereof have not exercised their
respective rights of renewal or expansion as to such premises contained in their
respective leases or such rights have expired; and (ii) as to the Non-Leased 250
Space, any tenant of Suite 250 has not exercised the right of expansion
contained in its lease as to the Non-Leased 250 Space or such right has expired.
Subject to the foregoing, in
<PAGE>

the event any Subordinated Space becomes available for lease during the Term (or
the renewal term, subject to the provisions of Article 38(c) below), Landlord
shall give written notice thereof to Tenant (the "Notice From Landlord"). Tenant
shall have fifteen (15) days after receipt of the Notice From Landlord within
which to deliver to Landlord written notice of Tenant's exercise of this offer
(the "Notice of Exercise"), time being of the essence; provided that it shall be
a condition precedent to the effectiveness of Tenant's delivery of a Notice of
Exercise that Tenant is not in default in the performance of its obligations
under this Lease as of the date of Tenant's delivery of the Notice of Exercise.
Notwithstanding anything in this Article 38 to the contrary, if Tenant is in
default under this Lease and if the default is a default under Article 20.A.(i),
(vi) or (vii) (each a "Curable Default") or a default under Article 20.A.(viii)
as to which Landlord has given less than twenty (20) days notice, Landlord shall
give the Notice From Landlord as to the Subordinated Space, it being understood
and agreed that if (i) Tenant does not cure the defaults within the cure periods
provided in said Article 20.A.(i), (vi) or (vii) therefor, or, by the end of the
twentieth day after the effective date of the notice as to a default under
Article 20.A.(viii); or (ii) the default is a default under Article 20.A.(iii),
(iv), (v) or (viii) (as to which Landlord has given Tenant more than twenty days
notice as of the date Landlord gives the Notice From Landlord) (each, an
"Uncurable Default"), Landlord may rescind the Notice From Landlord without
further notice to Tenant and lease the Subordinated Space in question to any
party on any terms.

     (b)  First Floor Space. Tenant shall have the right to lease Suites 130 and
          -----------------
150 (each, singly, a "First Floor Space" and collectively, the "First Floor
Spaces"; the Subordinated Space and the First Floor Space may be referred to
hereinafter singly or collectively as an "Offer Space") by giving written notice
(such notice, as to each First Floor Space, a First Floor Space Notice of
Exercise") to Landlord not later than July 31, 2003, as to Suite 130 and
February 28, 2003, as to Suite 150; provided however, that if Tenant is in
default under this Lease and:

     (i)  if the default is a Curable Default, Tenant shall have no right to
          give any First Floor Space Notice of Exercise and, if given, Landlord
          shall have no obligation to accept such First Floor Space Notice of
          Exercise until such default is cured, it being understood and agreed
          that, notwithstanding any provision of Article 20.A to the contrary,
          Tenant must cure such default by the earlier of (A) the time for cure
          set forth in Article 20.A.(i), (vi), (vii) or (viii); or (B) July 31,
          2003, as to Suite 130 and February 28, 2003 as to Suite 150; or

     (ii) if the default is an Uncurable Default (other than a default under
          Article 20.A.viii), Tenant shall have no right to give any First Floor
          Space Notice of Exercise and, if given, Landlord shall have no
          obligation to accept such First Floor Space Notice of Exercise,

and, in either of such cases, Landlord without further notice to Tenant may
lease the First Floor Space in question to any party on any terms.

     (c)  Offer Space Generally. All terms and conditions of Tenant's lease of
          ---------------------
all or a portion of the Offer Space (including the expiration date thereof)
shall be as provided in this Lease, except that (I) minimum rental for the Offer
Space shall be the then-current Market Rent (as defined in Article 40 of this
Lease); (ii) Landlord shall provide tenant improvements to the Offer Space in a
manner and amount consistent with the provision of tenant improvements to
tenants entering into new leases in Plymouth Business Center for three-year
terms as of the date of the Notice from Landlord or the date of the First Floor
Space Notice of Exercise under consideration; and (iii) the term of the lease of
the Offer Space shall be three (3) years (the "Offer Space Term"), it being
understood and agreed that if the expiration date of the Offer Space Term will
occur after the Expiration Date, then, in the Notice of Exercise or the First
Floor Space Notice of Exercise, as the case may be, Tenant shall specify whether
it wishes to extend the Term such that the Expiration Date shall be co-terminous
with the expiration date of the Offer Space Term, which extension shall not
constitute an exercise of Tenant's right to renew this Lease pursuant to Article
39 hereof and in such case, the minimum Rental payable for the Premises for the
period commencing on the day after the Expiration Date and the expiration date
of the Offer Space Term shall be the then-current Market Rent. As to the
Subordinated Space, the Notice of Exercise shall contain the same essential
terms as the terms set forth in the Notice From Landlord and shall be in a form
sufficient to serve as a commitment by Tenant to enter into a lease amendment
with Landlord containing such terms with respect to the Offer Space as are
identified in the Notice From Landlord, together with, if applicable, Tenant's
notice that it wishes to extend the Term such that the Expiration Date shall be
co-terminus with the expiration date of the Offer Space Term as provided in the
preceding sentence. As to a First Floor Space Notice of Exercise, within fifteen
(15) days after request thereof from Landlord, Tenant shall execute and deliver
to Landlord those instruments which Landlord may request to evidence the lease
of the First Floor Space under consideration. Promptly upon Tenant's delivery of
the Notice of Exercise or a First Floor Space Notice of Exercise, the parties
shall cooperate in the execution of an agreement modifying the terms hereof to
include the Offer Space under consideration as part of the Premises in
accordance with the terms contemplated in such Notice From Landlord and/or in
the instruments delivered by Landlord pursuant to the preceding sentence, and
otherwise in accordance with the provisions of this Article 38. Any Offer Space
leased by Tenant pursuant to this Article 38 shall be delivered to Tenant and
minimum rental and Operating Expenses therefor shall become due and payable, on
the earlier of (I) the date Tenant begins to conduct its business in the Offer
Space under consideration; or (ii) the ninety-first day after Landlord legally
obtains possession of the Offer Space under consideration. If Tenant fails to
deliver the Notice of Exercise within said fifteen (15) day time period, or if
Tenant fails to deliver a First Floor Space Notice of Exercise within the time
period set forth therefor in this Article 38, Tenant shall be deemed to have
waived that right of first offer and shall have no further right to lease that
<PAGE>

portion of the Offer Space until the same again becomes available for re-leasing
during the Term (and any renewal term subject to the conditions of this Article
38(c). If Tenant waives its right to lease the Offer Space either in writing or
in accordance with the preceding sentence, Landlord shall be free to lease the
Offer Space identified in any Notice of Exercise or First Floor Space Notice of
Exercise thereafter to any party upon any terms. The rights of Tenant under this
Article 38 shall not be severed from this Lease or separately sold, assigned, or
otherwise transferred. The right of first offer contemplated by this Article 38
shall automatically terminate and become null and void and of no further force
and effect upon the earliest to occur of (I) the Expiration Date or earlier
termination of this Lease, (ii) the termination of the Tenant's right to
possession of the Premises, or (iii) the failure of Tenant to timely or properly
exercise the rights granted by this Article 38. The right contemplated by this
Article shall not survive the expiration or termination of this Lease, and shall
not be available to any subtenant of Tenant's interests hereunder; provided
however that, Tenant shall have the right of first offer as to all of the Offer
Space described in this Article 38 during the renewal term described in Article
39 hereof so long as, during the Term, no Event of Default has occurred
hereunder or under the Work Letter Agreement or any storage space or parking
license entered into by Landlord and Tenant.

     (d)  Second Floor Leases.  As to any lease it negotiates with a third-party
          -------------------
tenant for space on the second floor of the Building, which lease has a
commencement date prior to August 1, 2002, Landlord agrees to limit the term of
any such lease(s) to three (3) years.

ARTICLE 39 - RIGHT TO RENEW LEASE

     Landlord hereby grants to Tenant a one-time option to renew the Lease as to
the Premises, as the same may have been expanded pursuant to Article 38 hereof,
upon the terms and conditions of this Article 39 if:

     (a)  Tenant is not in default under this Lease, as the same may have been
          renewed beyond any time to cure at the time such option is exercised
          and as of the commencement date of the renewal term; and

     (b)  Tenant gives Landlord written notice of the exercise of the renewal of
          this Lease not earlier than the fourth anniversary of the Commencement
          Date and not later than nine months prior to the end of the Term (the
          "Renewal Notice of Exercise"), time being of the essence. Tenant's
          failure to notify Landlord of its intent to exercise the option to
          renew the Term granted herein on or before the dates specified in this
          subparagraph (b) for such renewal shall be deemed a waiver of Tenant's
          right to exercise its option to renew. Landlord and Tenant agree that
          if, prior to the date Tenant delivers the Renewal Notice of Exercise,
          Tenant has leased any Offer Space (as defined in Article 38 hereof),
          the Renewal Notice of Exercise and the subsequent renewal of this
          Lease pursuant to this Article 39 shall include and be applicable to
          such Offer Space. Landlord and Tenant further agree that, except as
          expressly provided in said Article 38, any right of first offer
          granted by said Article 38 shall expire as of the original Expiration
          Date of this Lease and shall not be available during the renewal term.

     If Tenant elects to renew this Lease under this Article 39, the following
terms and conditions shall apply:

     (x)  the renewal term in question shall commence upon the expiration of the
          Term and continue thereafter for a period of five (5) years;

     (y)  Minimum Rental for the Premises (as the same may have been expanded
          pursuant to Article 38) for the renewal term shall be Market Rent (as
          defined in Article 40 of this Lease); and

     (z)  all of the other terms and conditions contained in this Lease, as it
          may have been amended from time to time, shall be as set out in this
          Lease, it being understood that there shall be no rights of renewal or
          extension except as provided in this Article 39, and, upon the
          exercise of the right of renewal granted by this Article 39, this
          Article 39 shall be of no further force or effect and Tenant shall
          have no right to further renew or extend the Term at the expiration of
          the renewal term.

Within fifteen (15) days after request thereof from Landlord, Tenant shall
execute and deliver to Landlord those instruments which Landlord may request to
evidence the renewal described in this Article 39. The rights of Tenant under
this Article 39 shall not be severed from this Lease or separately sold,
assigned, or otherwise transferred, and shall expire on the expiration or
earlier termination of this Lease. Notwithstanding the foregoing, the renewal
option contemplated by this Article 39 shall automatically terminate and become
null and void and of no further force and effect upon the earlier to occur of
(I) the expiration or termination of this Lease, (ii) the termination of the
Tenant's right to possession of the Premises, or (iii) the failure of Tenant to
timely or properly exercise the rights granted by this Article 39. The right

interests hereunder.

ARTICLE 40 - MARKET RENT

     "Market Rent" means the amount of minimum rental, which will include
concessions, improvements and other matters (exclusive of Operating Expenses)
which Landlord would receive by then renting similar space (including similar
square footage) for premises in the Building. If (a) Tenant has delivered (I) a
Renewal Notice of Exercise; or (ii) a First Floor Space Notice of Exercise, in
either case, within forty-five (45) days after Landlord's receipt of the Renewal
Notice of Exercise or the First Floor Space Notice of Exercise, as the case may
be, Landlord shall deliver to Tenant its determination of Market Rent for the
renewal term or the Offer Space covered by the First Floor Space Notice of
Exercise; or (b) Landlord delivers a Notice From Landlord, Landlord shall
include therein Landlord's determination of Market Rent for the Offer Space (in
the case of any of (a)(I), (a)(ii) or (b) above, Landlord's determination of
Market Rent a "Market Rent Notice"). If Tenant does not agree with Landlord's
determination of Market Rent as set forth in the Market Rent Notice, Tenant
shall so notify Landlord in writing within ten (10) days after Tenant's receipt
of the Market Rent Notice ("Tenant's Notice"). Landlord and Tenant shall, for
twenty (20) days after Landlord's receipt of Tenant's Notice, negotiate in good
faith to come to an agreement as to Market Rent for the renewal term or for the
Offer Space, as the case may be. If Landlord and Tenant are unable to agree upon
Market Rent within said twenty (20) day period, then, notwithstanding the
provisions of Articles 38 and 39, Tenant shall have the right to rescind the
Renewal Notice of Exercise, the First Floor Space Notice of Exercise or the
Notice of Exercise by written notice (in either case the "Rescission Notice") to
Landlord given not later than thirty (30) days after the date of Tenant's
Notice, it being understood and agreed that if the Rescission Notice is not
given within such time period, Tenant shall be deemed to have waived its right
to rescind the Renewal Notice of Exercise the First Floor Space Notice of
Exercise or the Notice of Exercise, as the case may be. In such case, to the
extent that the Renewal Notice of Exercise, the First Floor Space Notice of
Exercise or the Notice of Exercise, as the case may be, has been effectively
exercised, Landlord and Tenant shall execute and deliver an amendment to this
Lease as provided in Article 38 or 39, as the case may be, which amendment shall
be executed and delivered within fifteen (15) days following the determination
of Market Rent. Tenant's failure to give Tenant's Notice within the time period
provided above shall be deemed an acceptance of Landlord's determination of
Market Rent, and Tenant shall be deemed to have agreed to renew the term
pursuant to the Renewal Notice of Exercise or to lease the Offer Space pursuant
to the Notice of Exercise or the First Floor Space Notice of Exercise, as the
case may be.

     IN WITNESS WHEREOF, this Lease Agreement has been duly executed by the
parties hereto as of the day and year indicated above.

                             Work Letter Agreement
                           [Landlord Performs Work]
                                  [Allowance]

     This Work Letter Agreement ("Work Letter") is dated October 19, 1999, and
is a part of that certain Lease Agreement (the "Lease") between VITAL IMAGES,
INC., a Minnesota corporation, as "Tenant" and ST. PAUL PROPERTIES, INC., a
Delaware corporation, as "Landlord," relating to certain demised premises
("Premises") at that certain building having a street address of 3300 Fernbrook
Lane, Plymouth, Minnesota (the "Building"), which Premises are more fully
identified in the Lease. Capitalized terms used herein, unless otherwise defined
in this Work Letter, shall have the respective meanings ascribed to them in the
Lease.

      For and in consideration of the agreement to lease the Premises and the
mutual covenants contained herein and in the Lease, Landlord and Tenant hereby
agree as follows:

     1.   Tenant's Initial Plans; the Work. Tenant desires Landlord to perform
          ---------------------------------
certain leasehold improvement work in the Premises in substantial accordance
with the plan or plans (collectively, the "Initial Plan") prepared by Jafvert
Mueller Architects, Inc. dated September 1, 1999 and last revised September 13,
1999, a copy or copies is/are attached hereto as Schedule 1. Such work, as shown
in the Initial Plan and as more fully detailed in the Working Drawings (as
defined and described in Paragraph 2 below), shall be hereinafter referred to as
the "Work." Not later than October 15, 1999, Tenant shall furnish to Landlord
such additional plans, drawings, specifications and finish details as Landlord
may reasonably request to enable Landlord's architects and engineers to prepare
mechanical, electrical and plumbing plans and to prepare the Working Drawings,
it being understood and agreed that if a final telephone layout and special
electrical connection requirements, if any are not included in the submission to
Landlord, Tenant shall be responsible, at its sole cost and expense, for the
inclusion of such items in the Working Drawings (including any changes to the
Working Drawings necessitated by the inclusion of the telephone layout and
special electrical connection requirements) and into the Premises. All plans,
drawings, specifications and other details describing the Work which have been
or are hereafter furnished by or on behalf of Tenant shall be subject to
Landlord's approval, which Landlord agrees shall not be unreasonably withheld.
Landlord shall not be deemed to have acted unreasonably if it withholds its
approval of any plans, specifications, drawings or other details or of any
Additional Work (as defined in Paragraph 7 below) because, in Landlord's
reasonable opinion, the work, as described in any such item, or the Additional
Work, as the case may be: (a) is likely to adversely affect Building systems,
the structure of the Building or the safety of the Building and/or its
occupants; (b) might impair Landlord's ability to furnish services to Tenant or
other tenants in the Building; (c) might, in Landlord's sole opinion, adversely
affect Landlord's ability to re-lease the Premises; (d) would increase the cost
of operating the Building; (e) would violate any governmental laws, rules or
ordinances (or interpretations thereof); (f) contains or uses hazardous or toxic
materials or substances; (g) would adversely affect the appearance of the
Building; (h) might adversely affect another tenant's premises; (I) is
prohibited by any ground lease affecting the Building or any mortgage or other
instrument encumbering the Building; or (j) is likely to be substantially
delayed because of unavailability or shortage of labor or materials necessary to
perform such work or the difficulties or unusual nature of such work. The
foregoing reasons, however, shall not be the only reasons for which Landlord may
withhold its approval, whether or not such other reasons arc similar or
dissimilar to the foregoing. Neither the approval by Landlord of the Work or the
Initial Plan or any other plans, drawings, specifications or other items
associated with the Work nor Landlord's performance, supervision or monitoring
of the Work shall constitute any warranty by Landlord to Tenant of the adequacy
of the design for Tenant's intended use of the Premises.

     2.   Working Drawings. If necessary for the performance of the Work and not
          ----------------
included as part of the Initial Plan, Landlord shall prepare or cause to be
prepared final working drawings and specifications for the Work (the "Working
Drawings") based on and consistent with the Initial Plan and the other plans,
drawings, specifications, finished details and other information furnished by
Tenant to Landlord and approved by Landlord pursuant to Paragraph 1 above. So
long as the Working Drawings are consistent with the Initial Plan, Tenant shall
approve the Working Drawings within five (5) days after receipt of same from
Landlord by initialing and returning to Landlord each sheet of the Working
Drawings or by executing Landlord's approval form then in use, whichever method
of approval Landlord may designate. Subject to subparagraphs (a) - (j) of
Paragraph 1 above, provided Tenant has delivered to Landlord its additional
plans, drawings, specifications and finish details on or before October 15,
1999, Landlord shall cause the Working Drawings to be prepared not later than
October 22, 1999, and Tenant shall approve the Working Drawings not later than
October 29, 1999.

     3.   Performance of the Work; Allowance. Except as hereinafter provided to
          -----------------------------------
the contrary, Landlord shall cause the performance of the Work using (except as
may be stated or shown otherwise in the Working Drawings) building standard
materials, quantities and procedures then in use by Landlord ("Building
Standards"). Landlord shall pay for a portion of the "Cost of the Work" (as
defined below) in an amount not to exceed $413,491.00 (the "Allowance"), which
amount shall be based on a per square foot rate of $17.00 per rentable square
foot of the Premises, and which amount shall be increased or decreased in
accordance with Paragraph 1 of the Lease. Tenant shall pay for the entire Cost
of the Work in excess of the Allowance. Tenant
<PAGE>

shall not be entitled to any credit, abatement or payment from Landlord in the
event that the amount of the Allowance specified above exceeds the Cost of the
Work. For purposes of this Agreement, the term "Cost of the Work" shall mean and
include any and all costs and expenses of the Work, including, without
limitation, the cost of the Initial Plan, the Working Drawings, the cost of an
employee of Landlord or Landlord's Managing Agent acting as tenant
coordinator/construction manager and all labor (including overtime) and
materials constituting the Work; provided however, that the amounts payable for
such coordinator construction manager shall not exceed the sum of (a) three
percent (3%) of the Cost of the Work as to supervisory fees; and (b) five
percent (5%) of the Cost of the Work as to overhead and general conditions.

     4.   Payment. Not later than ten (10) days after Landlord's approval of the
          -------
Working Drawings, Landlord shall cause its contractor to provide a to Tenant a
list of all subcontractors to whom its contractor intends to ask to submit bids
for the performance of a portion of the Work. Landlord and Tenant may elect to
add subcontractors to such list or to delete contractors therefrom, it being
understood and agreed that Landlord and Tenant shall mutually approve all of
such subcontractors, and from such mutually approved list, Landlord shall select
the lowest qualified bidder. In addition to the list of subcontractors, Landlord
shall submit to Tenant a written statement of the total Cost of the Work (which
shall include the amount of any overtime projected as necessary to substantially
complete the Work by the Commencement Date specified in the Lease) as then known
by Landlord, and such statement shall indicate the amount, if any, by which the
total Cost of the Work exceeds the Allowance (the "Excess Costs"). Tenant
agrees, within three (3) days after submission to it of such statement, to
execute and deliver to Landlord, in the form then in use by Landlord, an
authorization to proceed with the Work, and Tenant shall also then pay to
Landlord an amount equal to the Excess Costs. No Work shall be commenced until
Tenant has fully complied with the preceding provisions of this Paragraph 4. In
the event, and each time, that any change order by Tenant, unknown field
condition, delay caused by acts beyond Landlord's control causes the Cost of the
Work to be increased after the time that Landlord delivers to Tenant the
aforesaid initial statement of the Cost of the Work, Landlord shall deliver to
Tenant a revised statement of the total Cost of the Work, indicating the revised
calculation of the Excess Costs, if any. Within three (3) days after submission
to Tenant of any such revised statement, Tenant shall pay to Landlord an amount
equal to the Excess Costs, as shown in such revised statement, less the amounts
previously paid by Tenant to Landlord on account of the Excess Costs, and
Landlord shall not be required to proceed further with the Work until Tenant has
paid such amount. Delays in the performance of the Work resulting from the
failure of Tenant to comply with the provisions of this Paragraph 4 shall be
deemed to be delays caused by Tenant.

     5.   Substantial Completion. Landlord shall cause the Work to be
          ----------------------
"substantially completed" on or before the scheduled date of commencement of the
Term subject to delays caused by strikes, lockouts, boycotts or other labor
problems, casualties, discontinuance of any utility or other service required
for performance of the Work, unavailability or shortages of materials or other
problems in obtaining materials necessary for performance of the Work or any
other matter beyond the control of Landlord (or beyond the control of Landlord's
contractors or subcontractors performing the Work) and also subject to "Tenant
Delays" (as defined and described in Paragraph 6 of this Work Letter). The Work
shall be deemed to be "substantially completed" for all purposes under this Work
Letter and the Lease if and when Landlord's general contractor issues a written
certificate to Landlord and Tenant, certifying that the Work has been
substantially completed (i.e., completed except for "punchlist" items listed in
such architect's certificate, which "punchlist items" shall include the items in
the "punchlist" contemplated by Article 1 of the Lease) in substantial
compliance with the Working Drawings, or when Tenant first takes occupancy of
the Premises, whichever first occurs. If the Work is not deemed to be
substantially completed on or before the scheduled date of the commencement of
the Term, (a) Landlord agrees to use reasonable efforts to complete the Work as
soon as practicable thereafter, (b) the Lease shall remain in full force and
effect, (c) Landlord shall not be deemed to be in breach or default of the Lease
or this Work Letter as a result thereof and Landlord shall have no liability to
Tenant as a result of any delay in occupancy (whether for damages, abatement of
Rent or otherwise), and (d) except in the event of Tenant Delays and
notwithstanding anything contained in the Lease to the contrary, the
Commencement Date of the Term shall be extended to the date on which the Work is
deemed to be substantially completed and the Expiration Date of the Term shall
be extended by the number of days by which the Commencement Date was extended
together with the number of days required to make the Term expire on the next
occurring last day of the month. At the request of either Landlord or Tenant in
the event of such extensions in the commencement and expiration dates of the
Term, Tenant and Landlord shall execute and deliver an amendment to the Lease
reflecting such extensions. Landlord agrees to use reasonable diligence to
complete all punchlist work listed in the aforesaid general contractor's
certificate promptly after substantial completion.

     6.   Tenant Delays. There shall be no extension of the scheduled
          -------------
commencement or expiration date of the Term (as otherwise permissibly extended
under Paragraph 5 above) if the Work has not been substantially completed on
said scheduled commencement date by reason of any delay attributable to Tenant
("Tenant Delays"), including without limitation:

          (a) the failure of Tenant to furnish all or any plans, drawings,
     specifications. Finish details or the other information required under
     Paragraph 1 above on or before the date stated in Paragraph 1;

          (b) the failure of Tenant to grant approval of the Working Drawings
     within the time required under Paragraph 2 above;

          (c) the failure of Tenant to comply with the requirements of Paragraph
     4 above;
<PAGE>

          (d) Tenant's requirements for special worker materials, finishes, or
     installations other than the Building Standards or Tenant's requirements
     for special construction staging or phasing;

          (e) the performance of any Additional Work (as defined in Paragraph 7
     below) requested by Tenant or the performance of any work in the Premises
     by any person, firm or corporation employed by or on behalf of Tenant, or
     any failure to complete or delay in completion of such work; or

          (f) any other act or omission of Tenant.

     7.   Additional Work. Upon Tenant's request and submission by Tenant (at
          ---------------
Tenant's sole cost and expense) of the necessary information and/or plans and
specifications for work other than the Work described in the Working Drawings
("Additional Work") and the approval by Landlord of such Additional Work, which
approval Landlord agrees shall not be unreasonably withheld, Landlord shall
perform such Additional Work, at Tenant's sole cost and expense, subject,
however, to the following provisions of this Paragraph 7. Prior to commencing
any Additional Work requested by Tenant, Landlord shall submit to Tenant a
written statement of the cost of such Additional Work, and, concurrently with
such statement of cost, Landlord shall also submit to Tenant a proposed tenant
extra order (the "TEO") for the Additional Work in the standard form then in use
by Landlord. Tenant shall execute and deliver to Landlord such TEO and shall pay
to Landlord the entire cost of the Additional Work within five (5) days after
Landlord's submission of such statement and TEO to Tenant. If Tenant fails to
execute or deliver such TEO or pay the entire cost of such Additional Work
within such 5-day period, then Landlord shall not be obligated to do any of the
Additional Work and may proceed to do only the Work, as specified in the Working
Drawings.

     8.   Tenant Access. Landlord, in Landlord's reasonable discretion and upon
          -------------
request by Tenant, will grant to Tenant a license to have access to the Premises
prior to the date designated in the Lease for the commencement of the Term to
allow Tenant to do other work required by Tenant to make the Premises ready for
Tenant's use and occupancy (the "Tenant's Pre-Occupancy Work"). It shall be a
condition to the grant by Landlord and continued effectiveness of such license
that:

          (a) Tenant shall give to Landlord a written request to have such
     access to the Premises not less than five (5) days prior to the date on
     which such access will commence, which written request shall contain or
     shall be accompanied by each of the following items, all in form and
     substance reasonably acceptable to Landlord: (I) copies of all plans and
     specifications pertaining to Tenant's Pre-Occupancy Work; (ii) copies of
     all licenses and permits required in connection with the performance of
     Tenant's Pre-Occupancy Work; (iii) certificates of insurance (in amounts
     satisfactory to Landlord and with the parties identified in, or required
     by, the Lease named as additional insureds) and instruments of
     indemnification against all claims, costs, expenses, damages and
     liabilities which may arise in connection with Tenant's Pre-Occupancy Work;
     and (iv) assurances of the ability of Tenant to pay for all of Tenant's
     Pre-Occupancy Work and/or a letter of credit or other security deemed
     appropriate by Landlord securing Tenant's lien-free completion of Tenant's
     Pre-Occupancy Work.

          (b) Such pre-Term access by Tenant and its representatives shall be
     subject to scheduling by Landlord.

          (c) Tenant's employees, agents, contractors, workers, mechanics,
     suppliers and invitees shall work in harmony and not interfere with
     Landlord or Landlord's agents in performing the Work and any Additional
     Work in the Premises, Landlord's work in other premises and in common areas
     of the Building, or the general operation of the Building. If at any time
     any such person representing Tenant shall cause or threaten to cause such
     disharmony or interference, including labor disharmony, and Tenant fails to
     immediately institute and maintain such corrective actions as directed by
     Landlord, then Landlord may withdraw such license upon twenty-four (24)
     hours' prior written notice to Tenant.

          (d) Any such entry into and occupancy of the Premises by Tenant or any
     person or entity working for or on behalf of Tenant shall be deemed to be
     subject to all of the terms, covenants, conditions and provisions of the
     Lease, specifically the provisions regarding Tenant's improvements and
     alterations to the Premises, and excluding only the covenant to pay Rent.
     Landlord shall not be liable for any injury, loss or damage which may occur
     to any of Tenant's Pre-Occupancy Work made in or about the Premises or to
     property placed therein prior to the commencement of the Term, the same
     being at Tenant's sole risk and liability. Tenant shall be liable to
     Landlord for any damage to the Premises or to any portion of the Work or
     Additional Work caused by Tenant or any of Tenant's employees, agents,
     contractors, workmen or suppliers. In the event that the performance of
     Tenant's Pre-Occupancy Work causes extra costs to Landlord or extraordinary
     use of Building services, Tenant shall reimburse Landlord for such extra
     cost and/or shall pay Landlord for such elevator service or other Building
     services at Landlord's standard rates then in effect.

It is understood and agreed that a breach by Tenant of any of the foregoing
conditions shall constitute a Tenant Delay, and shall modify Landlord's
obligation to deliver the Premises to Tenant by the Commencement Date pursuant
to Article 5(b) hereof for the number of days attributable to such delay.

they are applicable to this Work Letter, are hereby incorporated herein by

     Landlord performs the Work without the necessity of preparing working
     drawings and specifications, then whenever the term "Working Drawings" is
     used in this Agreement, such term shall be deemed to refer to the Initial
     Plan and all supplemental plans and specifications approved by Landlord.

     11.  Limitation of Landlord's Liability. Tenant agrees to look solely to
          ----------------------------------
Landlord's interest in the Building, the proceeds of any sale thereof and, to
the extent Landlord is then entitled thereto, rents and profits arising from the
leases of premises in the Building for the recovery of any judgment from
Landlord, it being agreed that Landlord and Landlord's partners, whether general

shareholders (if Landlord is a corporation), shall never be personally liable
for any such judgment. Nothing in the preceding sentence shall be deemed to
allow Tenant to set off or deduct any amount owed to Tenant by Landlord
hereunder against any payment of Rent due under this Lease Agreement at any
time.

     12.  Lease Provisions. The terms and provisions of the Lease are hereby
          ----------------

remedies provided for in the Lease. The pursuit of any remedies by Tenant in
connection with any breach by Landlord of its obligations under this Work Letter
shall be subject to the provisions of Paragraph 11 hereof and subject to any
other limitations stated in the Lease.

     IN WITNESS WHEREOF, the parties have executed this Work Letter Agreement as
of the date first written above.
