                                      LEASE

This Lease entered into as of this 16 day of September, 1998, is by and between
BLN Office Park Associates II Limited Partnership, a Minnesota limited
partnership (hereinafter "Landlord") and Adaytum KPS Software Limited
(hereinafter "Tenant").

WITNESSETH THAT:

1. BLN OFFICE PARK. BLN Office Park Associates and BLN Office Park Associates II
Limited Partnership are affiliated entities which together own the BLN Office
Park, a two-building office complex located at 2001 and 2051 Killebrew Drive,
Bloomington, Minnesota 55425, legally described as Lots 1 and 2, Block One, MCMI
Second Addition according to the duly recorded plat thereof, Hennepin County,
Minnesota, and which includes underground parking facilities, surface parking,
walking areas, landscaped areas and certain common areas and facilities that are
shared with occupants of other space in the building and with occupants of space
in the other building in the BLN Office Park, under rules and regulations as
instituted by Landlord from time to time.

2. LEASED PREMISES. Landlord does hereby lease to Tenant, and Tenant does hereby
take from Landlord, those certain premises comprising approximately 10,300
square feet of rentable area hatched in red on EXHIBIT A attached hereto
(hereinafter the "Leased Premises"). The Leased Premises was measured in
accordance with BOMA Standards. The Leased Premises are located at 2051
Killebrew Drive.

3. TERM. The lease term shall commence on the 1st day of January, 1999
(hereinafter "Commencement Date") and shall continue thereafter to and including
the 31th day of December, 2004, unless earlier terminated as hereinafter
provided.

4. BASE RENT. Tenant shall pay to Landlord during the lease term base rent in
monthly installments pursuant to the following Schedule:

         From the commencement of the lease term until December 31, 2004 the sum
         of $1,402,860.00 payable in equal monthly installments of $19,484.17 on
         the first day of the month during the lease term. The Base Rent is also
         subject to increase due to increases in operating costs and taxes, as
         described in paragraphs 5 and 6 below.

The monthly installments of Base Rent are due and payable in advance on the
first day of each month. Any installment which has not been received by the
Landlord by the 5th day of the month shall automatically and without notice be
increased by 5% to compensate the Landlord for its administrative overhead, loss
of use of funds and other incidental expenses.

5. CONTRIBUTION TO OPERATING COSTS. The Base Rent is predicated in part upon
Base Operating Costs on a per square foot basis of six dollars and 74/100 $6.74
(hereinafter "Base Operating Cost") consisting of two components $2.74 for real
estate taxes and $4.00 for other operating expenses. Prior to March 31, 1999,
and prior to the first day of each calendar year thereafter, Lessor shall
furnish Tenant with an Estimate of the Operating Costs for the ensuing calendar
year. The monthly installments of the Base Rent shall be increased or decreased
by one-twelfth of the product of the number of square feet of net rentable area
in the Leased Premises multiplied by the excess, if any, of such Estimate over
the Base Operating Costs. After the expiration of each calendar year, Lessor
shall furnish Tenant with a statement of the actual per square foot Operating
Costs for the preceding calendar year, and if the actual per square foot
Operating Costs for such preceding calendar year are more or less than the
Estimate, a proper adjustment shall be made; however, neither component of
Operating Costs shall be less than the respective figures stated above.
Provisions to the contrary hereinabove contained notwithstanding, the Base Rent
shall in no event be less than the amount stated in Paragraph 4. Tenant, at its
sole cost, will have the right to review Landlord's books as they relate to
Operating Costs if requested within ninety (90) days of being furnished the
actual Operating Costs Statement as outlined above.

         (a) DEFINITIONS. For the purposes of this Lease, the following terms
shall have the meanings set forth in this paragraph.




         (i) "Base Operating Cost" shall mean the Operating Costs (as that term
         is defined herein) attributed to the Leased


                                       2
<PAGE>

         Premises as of the Commencement Date. Base Operating Cost shall be
         divided into two components: Operating Expenses and Real Estate Taxes.
         Each part shall be determined and assessed independent of the other.
         "Operating Costs" means Operating Expense and Real Estate Taxes
         combined.

         (ii) "Operating Expenses" shall mean the following items. All costs
         incurred by Landlord in owning, managing, maintaining and operating the
         BLN Office Park, the appurtenances thereto and the underlying land,
         exclusive of interest and depreciation; an imputed management fee
         commensurate with the Minneapolis metropolitan market for management
         services, if at any time hereafter Landlord elects to manage the
         buildings; and all other expenditures which, for federal income tax
         purposes, may be expensed rather than capitalized. Notwithstanding
         anything contained herein to the contrary, Operating Expenses may, at
         the option of the Landlord, also include depreciation and interest
         costs for machinery, equipment systems, property or facilities
         installed in and used in connection with the BLN Office Park, provided
         that one of the major purposes for such installation or use is to
         reduce other items of Operating Expenses, and depreciation and interest
         costs for equipment provided or used by the Landlord in the normal
         maintenance of the Building.

         (iii) "Real Estate Taxes" shall mean the annual payment of real estate
         taxes and annual installments of special assessments levied against the
         BLN Office Park, the appurtenances and underlying land.

         (b) GENERAL CALCULATION OF OPERATING COSTS.

         (i) Operating Costs shall be determined on a per square foot basis by
         dividing total Operating Costs by the total number of square feet of
         rentable area in the BLN Office Park, which rentable area shall be
         determined in accordance with the space measuring standards of the
         Building Owners and Managers Association International (BOMA) in effect
         on the date of this Lease and which can change from time to time. For
         the purpose of calculating Operating Costs for any calendar year, if,
         at any time during such year, less than the entire rentable area of the
         BLN Office Park was occupied by tenants making full utilization of such
         area, then the Operating Costs for such year shall be calculated by
         using a total Operating Cost amount equal to the Operating Costs which
         would have been incurred by Landlord had such total occupancy and full
         utilization of the BLN Office Park existed. Landlord shall have the
         right, in its sole and reasonable discretion, to determine the method
         of calculating Operating Costs, to accomplish the goal of having the
         Tenants of BLN Office Park pay all Operating Costs in an equitable
         manner, including special adjustments or allocations as between the two
         buildings of the Office Park.

         (ii) For purposes of this Section 5, the Tenant's prorata share shall
         be the fraction having the number of rentable square feet of the Leased
         Premises as the numerator and the total rentable square feet in the BLN
         Office Park as the denominator, which fraction is 3.063%. Tenant will
         have the right to review Landlord's books as they relate to Operating
         Costs.

6.       ADDITIONAL TAXES. The Tenant shall pay, at the time and in the manner
specified herein, the following amounts as additional rent due hereunder:

         (a) Tenant shall pay, together with each monthly installment of Annual
         Base Rent, the amount of any gross receipts tax, sales tax or similar
         tax (but excluding therefrom any income tax) payable by Landlord by
         reason of Landlord's receipt of any amounts due to Landlord hereunder.

         (b) If any improvements are made to the Leased Premises by or at the
         insistence of the Tenant which are of a nature or quality beyond
         standard office space in the BLN Office Park, the Tenant shall pay to
         Landlord on the first day of each month during the lease term
         one-twelfth of the annual tax expenses as estimated by Landlord to be
         paid during the following calendar year that are attributable to such
         improvements. It is understood and agreed by the parties hereto that,
         if the amount of estimated annual tax expenses paid by the Tenant
         during each such year is lesser or greater than the amount of annual
         tax expenses actually attributable to the improvements made by Tenant,
         an appropriate adjustment shall be made. In the event such actual
         annual tax expenses are greater than as estimated, Tenant shall
         immediately pay the difference to the Landlord; in the event they are
         less than as estimated, Landlord


                                       3
<PAGE>

         shall credit the difference to the Tenant's account.

7.       USE AND INSURANCE RATING. Tenant shall use the Leased Premises for the
following purposes and for no other purposes whatsoever: general office use and
all uses incidental thereto.
Tenant will not conduct or permit to be conducted any activity or place any
equipment in or about the Leased Premises which will in any way increase the
rate of fire and extended coverage insurance or liability insurance on the
Building. If any increase in the rate of such insurance is stated by any
insurance company or by the applicable insurance rating bureau to be due to
activity or equipment of Tenant in or about the Leased Premises, such
statement shall be conclusive evidence that such increase in such rate is due
to such activity or equipment, and, as a result thereof, Tenant shall be
liable for such increase and shall reimburse Landlord therefor.

8.       SPACE ADJUSTMENTS. Tenant acknowledges that much of the rental space in
the Building may be rented in smaller units and, therefore, it may be necessary
for Landlord to make adjustments in Tenant's space or actually relocate Tenant
within the Building so that the space needs of all Tenants may be accommodated.
Tenant agrees that Landlord may, at any time, and from time to time, relocate
Tenant within the Building, provided that Landlord shall pay all Tenant's
reasonable direct costs incurred in connection therewith "including but not
limited to all costs of relocating Tenant's computer and telecommunications
equipment and cabling, and other personal property and fixtures, as well as the
cost of six months' supply of replacement stationery, business cards, marketing
material and other information sent by mail to clients, customers and other
professionals with whom Tenant transacts business." It is expressly agreed,
however, that Landlord shall have the right prior to Tenant's initial occupancy
to relocate Tenant without any charge to Landlord. Landlord's right to relocate
Tenant is conditioned only on the obligation that the new leased premises shall
be located in the BLN Office Park and shall not vary in size more than plus or
minus five percent (5%) from the Leased Premises. Tenant shall pay rentals based
on the actual rentable area calculated for the space occupied after such
relocation, whether said space is larger or smaller than the Leased Premises. If
Tenant shall be moved more than once, the new space shall never vary more than
ten percent (10%) from the originally estimated space.

9.       LEASEHOLD IMPROVEMENTS. Landlord agrees to provide those improvements
in the Leased Premises set forth on EXHIBIT B attached hereto. No later than
September 15, 1998, Tenant shall provide Landlord or with a detailed floor plan
layout, together with working drawings and written instructions (hereinafter
"Tenant's Plans"), sufficiently detailed to enable Landlord to construct the
various improvements indicated by Tenant on Tenant's Plans. After Tenant's Plans
have been approved by both Tenant and Landlord, Tenant may not make changes and
alterations in Tenant's Plans without Landlord's advance written approval. In
addition, Tenant agrees to reimburse Landlord immediately for such approved
changes and alterations in Tenant's Plans in an amount equal to Landlord's
actual cost for design and construction of Tenant's changes or improvements.

10.      NO WARRANTIES BY LANDLORD AND AGENTS/ACCEPTANCE OF PREMISES.

         (a) By signing this Lease, Tenant acknowledges and agrees that neither
         Landlord nor any agents or employee of Landlord have made any
         representations or promises with respect to the Leased Premises or BLN
         Office Park, except as expressly set forth herein, and no rights,
         privileges, easements or licenses are acquired by Tenant, except as
         expressly set forth herein.
         (b) The taking of possession of the Leased Premises by Tenant shall be
         conclusive evidence that, except for minor "punch list" items, latest
         defects, if any, the Leased Premises were on such date of possession in
         good, clean and


                                       4
<PAGE>

         tenantable condition and that the Tenant accepts the Leased Premises
         "as is." Said "punch list" will be submitted to Landlord within thirty
         (30) days of Tenant's taking possession of the Leased Premises.
         Landlord agrees to use due diligence to fix "punch list" items in a
         timely manner.

11.      TIME OF POSSESSION AND OCCUPANCY OF PREMISES. If the Leased Premises
shall, on the date of commencement of the Lease Term, be in the possession and
occupancy of any person not lawfully entitled thereto, Landlord shall use due
diligence to obtain possession thereof for Tenant. If the Leased Premises shall
not be ready for occupancy at said time because construction has not yet been
substantially completed or by reason of any building operations, repairing or
remodeling to be done by Landlord, or by reason of a tenant holding over,
Landlord shall use due diligence to make the Leased Premises ready for occupancy
by Tenant. It is agreed that Landlord and Landlord's agents and employees, using
due diligence, shall not in any way be liable to Tenant except as provided in
Section 9 of this Lease for any incidental or consequential damages resulting to
Tenant from failure to obtain possession of the Leased Premises for the Tenant
or to deliver the possession thereof to Tenant, and this Lease shall remain in
all things in full force and effect and the Lease Term shall not thereby be
extended, except that the monthly installments of Base Rent, additional rent and
other amounts payable hereunder shall be abated until the Landlord has made the
Leased Premises ready for occupancy; provided, however, if the Leased Premises
are not ready for occupancy by May 1, 1999, Tenant, at its option, shall have
the right to terminate this Lease by written notice.

12.      ASSIGNMENT AND SUBLETTING. "Tenant, on notice to Landlord (but without
Landlord's consent), may assign this Lease or sublet all or part of the Premises
to any of Tenant's Affiliates." Tenant's Affiliates shall mean any company
controlling, controlled by or under common control with Tenant, as well as any
entity acquiring all or substantially all of Tenant's assets. A transfer of an
ownership interest in Tenant shall not be deemed an assignment of this Lease,
but Tenant shall not be deemed an assignment of this Lease, but Tenant shall
give Landlord notice of any such transfer which results in a change in control
of Tenant, It being understood that Tenant will remain liable for all
obligations under this Lease. Tenant shall have the right to assign this Lease
or sublet all or any part of the Leased Premises with the prior written consent
of the Landlord, which consent shall not be unreasonably withheld, provided as
follows:

         (a) the Landlord may, in its sole discretion, withhold its consent to
         an assignment or a sublease (i) to any present tenant of Landlord in
         the BLN Office Park or any other location, (ii) to any tenant whose
         credit standing and financial statements are unsatisfactory to
         Landlord, or (iii) to any tenant whose occupancy would be inconsistent
         with the character of BLN Office Park;

         (b) such assignment or sublease shall not relieve Tenant of any of its
         obligations under this Lease;

         (c) any profit received from such assignment or sublease shall
         promptly, upon receipt thereof, be paid by Tenant to Landlord. "Profit"
         as used herein shall mean any amounts paid by an assignee or subtenant
         in excess of the Base Rent and additional rent attributable to the
         Leased Premises being assigned or sublet after deducting therefrom any
         amounts Tenant has paid for outside leasing commissions and reasonable
         tenant improvements occasioned by such assignment or subletting;

         (d) Tenant shall provide Landlord with notice of any assignment or
         sublease in writing, together with a copy of such assignment or
         sublease, and Landlord shall have 30 days from receipt thereof to make
         a decision concerning such assignment or sublease; and

         (e) any assignment or subletting made in violation of the provisions
         contained herein shall be ineffective.

13.      ALTERATIONS. Tenant will not make any alterations of or additions to
the Leased Premises which cost more than $5,000 per occasion or affect the
structure or exterior of the BLN Office Parkwithout the prior written approval
of Landlord. All work to be performed in the Leased Premises shall be performed
by competent contractors and subcontractors, approved by Landlord, which
approval shall not be unreasonably withheld by Landlord, except that Landlord
may in any event condition its approval of such contractors and subcontractors
on the Tenant's furnishing separate performance and payment surety bonds, or
other financial guaranties or deposits satisfactory to Landlord, covering any
work to be performed by such contractors or subcontractors on the Leased
Premises, and Landlord may, in any event, require that contractors and
subcontractors normally


                                       5
<PAGE>

employed by Landlord be engaged for any mechanical or electrical work and that
any alterations be done by contractors or subcontractors compatible with those
workmen, contractors and subcontractors employed from time to time in the BLN
Office Park by Landlord. All alteration work performed by or for Tenant
hereunder must be performed in such manner to avoid disruption of the BLN Office
Park operations or disturbance of other tenants in the BLN Office Park. Unless
Landlord requires the Tenant to restore the Leased Premises as set forth in this
Lease, all alterations, additions or improvements which may be made by either of
the parties hereto upon the Leased Premises, except office furnishings purchased
by Tenant which may be removed without damage or destruction to the Leased
Premises, shall be the property of Landlord and shall remain upon and be
surrendered with the Leased Premises as a part thereof at the termination of
this Lease or any extension thereof. Tenant will not permit any mechanics,
laborers or materialmen's liens to stand against the Leased Premises, the
Building or BLN Office Park for any labor or materials furnished to or in
connection with any work performed or claimed to have been performed in, on or
about the Leased Premises and will immediately remove all such liens. Tenant
further agrees that, in the event Tenant fails to remove any such lien or post a
bond therefore within thirty (30) days after receiving notice of such lien,
Landlord may remove such lien and Tenant shall immediately reimburse Landlord
upon demand for all costs and expenses, including attorneys' fees, incurred by
Landlord in removing such mechanic's or materialmen's lien.

14.      TENANT EQUIPMENT AND FURNISHINGS.

         (a) Tenant may install or operate in the Leased Premises any
         electrically operated equipment or other machinery which uses standard
         110-volt current and which Landlord determines in its reasonable
         judgment to constitute standard office equipment. Tenant shall not
         install any other equipment of any kind or nature whatsoever which will
         or may require any changes, replacements or additions to or in the use
         of the heating, air conditioning, electrical or plumbing systems of the
         Leased Premises or BLN Office Park without first obtaining the prior
         written consent of the Landlord. No plumbing fixtures of any type shall
         be installed within the Leased Premises without Landlord's written
         approval. If Tenant's business machines and mechanical equipment cause
         noise or vibration that may be transmitted to the structure of the BLN
         Office Park or to any space therein to such a degree as to be
         reasonably objectionable to Landlord or to any tenant in the Building,
         then Tenant shall install vibration eliminators or sound abatement
         measures or other devices sufficient to eliminate such noise and
         vibration at Tenant's cost. If Tenant uses heat generating machines or
         equipment (other than standard office equipment designated by Landlord
         as set forth above) in the Leased Premises which affect the temperature
         in the Leased Premises otherwise maintained by the air conditioning
         system furnished by Landlord as set forth in Section 15(a), Landlord
         reserves the right to install or to require Tenant to install adequate
         supplementary air conditioning equipment in the Leased Premises at
         Tenant's cost.

         (b) No furniture, equipment or other bulky items of any description
         will be received into the building or carried in the elevators, except
         as approved by Landlord. All moving of furniture, equipment and other
         materials shall be done during hours previously approved by Landlord
         and shall be under the direct control and supervision of Landlord or
         its agent. Landlord and its agents and representatives shall not be
         responsible for any damage to any of Tenant's personal property nor for
         any charges for moving the same. Tenant shall promptly remove from the
         public and common areas in the building and the BLN Office Park any of
         the Tenant's furniture, equipment or other material there delivered or
         deposited. Landlord shall have the right to limit the weight and
         prescribe the position of safes and other heavy equipment or fixtures.
         Any and all damage or injury to the Leased Premises or BLN Office Park
         caused by moving the property of Tenant in or out of the Leased
         Premises, or due to the same being on the Leased Premises, shall be
         repaired by and at the sole cost of Tenant.

following services to Tenant upon the terms and conditions set forth herein,
with the costs for such services being part of the Operating Costs:

         (a) HEATING, VENTILATION AND AIR CONDITIONING. Landlord agrees to

         temperature condition required in Landlord's reasonable judgment for
         comfortable occupancy of the Leased Premises under normal business
         operations daily from 8:00 a.m. to 6:00 p.m., Saturdays, Sundays and
         holidays excepted. Holidays shall mean the calendar days on which the
         following holidays fall or are observed; New Years Day, Memorial Day,
         Labor Day, Independence Day, Thanksgiving and Christmas.

         (c) ELECTRICITY. Landlord agrees to provide 110-volt current
         electricity to the Leased Premises for standard building lighting and
         office use during normal business hours. Any 110-volt equipment which
         is not reasonably energy-efficient shall not be deemed to be standard
         hereunder. Ordinary office use shall include, but not be limited to,
         the operation of office equipment, typewriters, word processors,
         personal computers, telephones, telecopy machines and photocopy

         normal business hours and will provide after hours access to Tenant in
         accordance with such reasonable rules, regulations and conditions as
         may be specified from time to time by Landlord and generally applicable
         to all tenants of the BLN Office Park.

16.      TENANT EQUIPMENT - ADDITIONAL UTILITIES AND COSTS.

         (a) If any electrical equipment, machinery, plumbing fixtures or other
         mechanical equipment installed or used by Tenant in the Leased Premises
         consumes or requires utility service in addition to those actual
         services to be furnished by Landlord pursuant to Section 15, Tenant
         shall promptly pay, as additional rent, all charges for such additional
         utilities and utility service furnished to the Leased Premises during
         the term of this Lease. If such utilities are separately metered to the
         Leased Premises, Tenant shall pay all such additional charges directly
         to the utility company furnishing the same. To the extent that
         utilities are furnished to the Leased Premises without separate
         metering, the amount which may be specifically charged to Tenant for
         additional utility usage shall be determined by Landlord on the basis
         of the actual costs incurred by Landlord in purchasing such additional
         utilities for use in the building.

         (b) Tenant shall also promptly pay to Landlord, as additional rent, all
         costs and expenses of installation, operation and maintenance of all
         electric lamps, starters and ballasts (but excluding the cost for light
         bulbs installed by Landlord prior to Tenant's initial possession of the
         Leased Premises) all additional electrical wiring caused by electrical
         equipment installed by Tenant with Landlord's approval other than the
         standard office equipment described in Section 14(a), any supplemental
         air conditioning equipment or vibration or noise elimination equipment
         described in Section 14(a), all plumbing fixtures and all additional
         sewer and water service used in or on the Leased Premises in addition
         to those described in Section 15(b).

17.      NO WARRANTY AS TO SERVICES. Landlord does not warrant that any of the
services it is required to provide under the terms of this Lease will be free
from interruption. Interruption of service shall never be deemed an eviction or
disturbance of Tenant's use and possession of the Leased Premises or any part
thereof, or render Landlord or Landlord's agents or employees liable to Tenant
for damages, or relieve Tenant from performance of Tenant's obligations under
this Lease. Landlord will use due diligence to restore the interrupted service
as soon as is reasonably possible to the extent that the interruption of service
is under the control of Landlord.

18.      ENERGY POLICIES. Wherever in this Lease any terms, covenants or
conditions are required to be performed by the Landlord, the Landlord shall be
deemed to have kept and performed such terms, covenants and conditions
notwithstanding any action taken by the Landlord, if such action is pursuant to
any governmental regulations, requirements or directives. Without limiting the
generality of the foregoing, the Landlord may reduce the quantity and quality of
all utility and any other services and impose such regulations as the Landlord
deems necessary in order to preserve energy. Landlord agrees that its
determination hereunder shall in all instances be reasonable.

19.      PROPERTY INSURANCE.


                                       7
<PAGE>

         (a) Landlord shall carry and cause to be in full force and effect a
         fire and extended coverage insurance policy for the full replacement
         value on the BLN Office Park, but not on the contents owned, leased or
         otherwise in possession of the Tenant. The cost of such insurance shall
         be an Operating Expense.

         (b) The Tenant shall carry and cause to be in full force and effect a
         fire and extended coverage insurance policy covering property of the
         Tenant within the BLN Office Park.

         (c) Landlord and Tenant hereby release each other from any and all
         liability or responsibility to the other or anyone claiming through or
         under them by way of subrogation or otherwise for any loss or damage to
         property caused by fire or any of the extended coverage or
         supplementary contract casualties, even if such fire or other casualty
         shall have been caused by the fault or negligence of the other party,
         or anyone for whom such party may be responsible, provided, however,
         that this release shall be applicable and in force and effect only with
         respect to loss or damage occurring during such time as the releasing
         party's policies shall contain a clause or endorsement to the effect
         that any such release would not adversely affect or impair said
         policies or prejudice the right of the releasing party to recover
         thereunder. Landlord and Tenant agree that they will request their
         insurance carriers to include in their policies such a clause or
         endorsement. If extra costs shall be charged therefor, each party shall
         advise the other of the amount of the extra cost and the other party,
         at its election, may pay the same, but shall not be obligated to do so.

         (d) Tenant shall be responsible for the security and safeguarding of
         the Leased Premises and all of its property kept, stored or maintained
         in the Leased Premises. In the event of any loss or damage to any of
         Tenant's property, Tenant agrees to look solely to its insurance
         carrier for recovery, irrespective of the cause of such loss or damage.

20.      PUBLIC LIABILITY.

         (a) Tenant will keep in force at its own expense for so long as this
         Lease remains in effect and for so long as Tenant occupies or has a
         right to occupy the Leased Premises, a policy of public liability with
         respect to the Leased Premises and the BLN Office Park in which policy
         Landlord shall be added named as an additional insured. This insurance
         will be with a company and in such a form as is reasonablyacceptable to
         Landlord, and shall have a minimum combined limit of liability, per
         location, of $1,000,000. The insurance shall also provide for
         contractual liability coverage by endorsement. Tenant will deposit with
         Landlord a certificate of insurance or other acceptable evidence, which
         evidence shall indicate that the Landlord will be notified in writing
         thirty (30) days prior to any cancellation, material change or failure
         to renew said insurance. Tenant covenants and agrees to indemnify and
         hold Landlord and Landlord's building managers and other agents and
         employees harmless from any claim, loss or damage, including reasonable
         attorney's fees, suffered by Landlord, Landlord's management agent,
         employees or other agents or Landlord's other tenants caused by: (i)
         any act or omission by Tenant, Tenant's employees or anyone claiming
         through or by Tenant in, at or around the Leased Premises or the BLN
         Office Park; (ii) the conduct or management of any work or thing
         whatsoever done by Tenant in or about the Leased Premises or the BLN
         Office Park, or (iii) Tenant's failure to comply with any and all
         governmental laws, rules, ordinances or regulations applicable to the
         use of the Leased Premises and its occupancy. If Tenant shall not
         comply with the covenants made in this paragraph, Landlord may, at its
         option, cause insurance to be issued and the costs thereof shall be
         billed to Tenant and shall thereafter become immediately due, as
         additional rent.

         (b) During the term of this Lease Agreement, Landlord shall also
         maintain a policy of public liability insurance in full force and
         effect with a combined single liability limit of at least $1,000,000,
         relative to the BLN Office Park location. Landlord hereby agrees to
         indemnify and hold Tenant, its contractors, employees, officers,
         partners and shareholders harmless from and against any and all costs,
         damages, claims, liabilities and expenses (including reasonable
         attorney's fees) suffered by or claimed against Tenant, resulting from
         gross negligence of Landlord or its employees or contractors in the BLN
         Office Park, or any failure of Landlord to comply with the terms of
         this Lease.

Premises or in the BLN Office Park. Tenant agrees to indemnify and hold Landlord
harmless from and against any damages as a result


                                       9
<PAGE>

of Tenant's violation of the provisions of this paragraph. Landlord represents
that it is unaware of any Hazardous Materials in the Leased Premises or the BLN

Landlord agrees to indemnify and hold Tenant harmless from and against any
damage or liability to Tenant or its agents, employees or invitees arising from
any Hazardous Materials which Landlord may have on the Leased Premises or in the

22.      FIRE OR OTHER CASUALTIES. If the Building is substantially damaged or
destroyed by fire or other casualty, the Landlord shall have the right to
terminate this Lease, provided it gives written notice thereof to the Tenant
within 90 days after such damage or destruction. If a portion of the Leased
Premises is damaged by fire or other casualty and Landlord elects not to
terminate this Lease, the Landlord shall, within a reasonable time and at its
own expense, restore the Leased Premises, exclusive of any alterations or other
changes made to the Leased Premises at any time by or at the direction or
request of Tenant, to as near the condition which existed immediately prior to
such damage or destruction as reasonably possible. In the event Landlord so
elects to restore the Leased Premises, rent shall abate during such period of
time as the Leased Premises are unusable in proportion that the unusable portion
of the Leased Premises shall bear to the entire Leased Premises. If the
destruction is so substantial that the Leased Premises cannot be substantially
restored within 180 days from the time of such damage or destruction, then the
Tenant shall have the right to terminate this Lease. The Landlord shall not be
responsible to the Tenant for damages to or destruction of any furniture,
equipment, alterations or other changes made or installed in, on or about the
Leased Premises by Tenant regardless of the cause of the damage or destruction.

23.      EMINENT DOMAIN. If the entire BLN Office Park or that portion of the
BLN Office Park which includes all or substantially all of the Leased Premises
is permanently taken by eminent domain, this Lease shall automatically terminate
as of the date of such taking. If any portion of the BLN Office Park is taken by
eminent domain, Landlord shall also have the right to terminate this Lease by
giving written notice thereof to Tenant within 90 days after the date of taking.
If only a portion of the Leased Premises is taken by eminent domain and Landlord
elects not to terminate this Lease, Landlord shall, at its expense, restore the
Leased Premises, exclusive of any improvements or other changes made to the
premises by Tenant, to as near the condition which existed immediately prior to
the date of taking as reasonably possible. Rent shall abate during such period
of time as the Leased Premises are unusable in proportion that the unusable
portion of the Leased Premises shall bear to the entire Leased Premises and,
upon completion of restoration, necessary adjustments shall be made in the Base
Rent, additional rent or other costs to reflect a reduction in the size of the
Leased Premises and/or the total rentable area of the BLN Office Park. Tenant
shall have no right to any of the award or payment made in connection with such
taking; provided, however, that Tenant shall be entitled to recover any separate
amount for Tenant fixtures and/or relocation costs provided under appropriate
statutes, ordinances or regulations.

24.      SIGNS. No sign, advertisement or notice shall be inscribed, painted,
affixed or displayed in any part of the outside or the inside of the BLN Office
Park, except that Tenant shall have the right at Tenant's cost to signage on the
building directories and doors of Tenant's offices , and then only in such
place, number, size, color and style as is approved by Landlord. Any such
permitted uses, excepting initial listing on directories in the main building
lobby and the standard building sign installed by Landlord for each Tenant,
shall be at the sole expense and cost of Tenant. If any such sign, advertisement
or notice is improperly exhibited, Landlord shall have the right to remove the
same without any legal proceeding, and Tenant shall be liable for any and all
expenses incurred by Landlord for said removal.

25.      WINDOW COVERINGS. Landlord, at its expense, will install window
coverings. Tenant shall maintain the window coverings so installed in an
attractive and safe condition and shall not change or alter such window
coverings without the written consent of Landlord.

26.      ACCEPTANCE OF TENANT'S GOODS. Tenant authorizes Landlord and Landlord's
agents and employees to accept and sign for shipments as a convenience and
measure of traffic control with a stamp which shall indicate that any signature
is authorized only to clear the loading dock or other receiving area as a matter
of convenience, and such signature does not constitute acceptance by the
addressee and does not relieve the carrier of any liability nor create an agency
or bailment. Tenant hereby releases Landlord and Landlord's agents and employees
from any and all liability resulting from or related to


                                       10
<PAGE>

the acceptance of goods addressed to Tenant and delivered to the Building's
loading dock or other area designated for receipt of goods.

27.      RULES AND REGULATIONS. Tenant shall use the Leased Premises and the
public and common areas in the BLN Office Park in accordance with such
reasonable rules, regulations and procedures as may, from time to time, be made
by the Landlord for the general safety, comfort and convenience of the owners,
occupants and tenants of the BLN Office Park and shall cause Tenant's employees
and invitees to abide by such rules and regulations. The current rules and
regulations are attached hereto as EXHIBIT D.

water and electricity, the use of the Leased Premises and of the public and
common areas in the Building and BLN Office Park and, without qualifying the
foregoing, shall not neglect or misuse water fixtures, electric lights and
heating and air conditioning apparatus.

Premises without the written consent of Landlord.

31.      LIGHT AND AIR. Tenant has no right to light or air over any premises
adjoining the Building or the BLN Office Park.

32.      LANDLORD'S RIGHT TO ENTER PREMISES. Landlord or its authorized agents
or attorneys may, at any reasonable time, following reasonable prior notice
enter the Leased Premises for the purposes of exhibiting the Leased Premises to
prospective tenants (during the final eight months of the term, as extended)or
purchasers to inspect, make repairs and improvements and/or changes in the
Leased Premises or other premises in the BLN Office Park, as Landlord may deem
proper. Landlord's reserved rights hereunder shall include, without limitation,
free, unhampered and unobstructed access to airways, equipment ducts, underfloor
heater ducts, stairways, access panels and all cleaning and utility services.
There shall be no diminution of rent or liability on the part of the Landlord by
reason of any inconvenience, annoyance or injury to business caused by
Landlord's exercise of the rights reserved by Landlord in this paragraph.

33.      SECURITY OF LEASED PREMISES. Tenant assumes full responsibility for
protecting the Leased Premises from theft, robbery and pilferage, which includes
keeping doors locked and other means of entry to the Leased Premises closed and
secured after normal business hours.

34.      REPAIRS. Tenant shall promptly pay to Landlord within ten (10) days of
receipt of an invoice thereof an amount equal to any cost incurred by Landlord
in repairing the Leased Premises and/or public and common areas in the building
or BLN Office Park when such repairs were made necessary by the negligence of or
misuse by the Tenant.

35.      LEASE TO BE SUBORDINATE. Landlord may cause this Lease to be made
subject and subordinate to all ground or underlying leases, mortgages and
restrictions which may now or hereafter affect the Building or BLN Office Park
and to all renewals and extensions thereof. Provided that Landlord shall make
commercially reasonable efforts to obtain a non-disturbance agreement from any
mortgagee. For confirmation of such subordination, Tenant shall execute promptly
any subordination agreement requested by Landlord. Tenant hereby irrevocably
constitutes and appoints Landlord as Tenant's agent to execute any such
subordination agreement or agreements for or on behalf of Tenant. Such
subordination is subject to Tenant enjoying the quiet possession of the Leased
Premises if any Mortgagee becomes landlord hereunder provided that Tenant is not
then in default hereunder or does not default in the future.

36.      ESTOPPEL CERTIFICATE. Tenant agrees, at any time and from time to time
upon not less than five business days prior written notice by Landlord, to
execute, acknowledge and deliver to Landlord a statement in writing:

         (a) Certifying that this Lease is unmodified and in full force and
         effect or, if there have been modifications, that this


                                       11
<PAGE>

         Lease is in full force and effect as modified and stating the
         modifications.

         (b) Stating the dates to which the rent and other charges hereunder
         have been paid by Tenant to Landlord.

         (c) Stating whether or not, to the best knowledge of Tenant, Landlord
         is in default in the performance of any covenants, agreements or
         conditions contained in this Lease and, if so, specifying each such
         default of which Tenant may have knowledge.

         (d) Responding to such other matters as Landlord reasonably requests.

Any such statement delivered pursuant hereto may be relied upon by any owner or
prospective purchaser of the building, any prospective mortgagee of the building
or Landlord's interest therein or any prospective assignee of any such
mortgagee.

37.      TENANT TO SURRENDER PREMISES IN GOOD CONDITION. Upon the expiration or
termination of the Lease Term, Tenant shall, at its expense:

         (a) Remove Tenant's goods and effects and those of all persons claiming
         through Tenant;

         (b) Quit and deliver up the Leased Premises to Landlord peaceably and
         quietly in as good order and condition as the same were on the date the
         Lease Term commenced or were thereafter placed in service by Lessor,
         reasonable wear and tear and damages from fire and other casualties
         excepted; and

(c) At Landlord's request, and if there have been alterations made to the Leased
Premises without any required explicit written consent, restore the Leased
Premises to general office standards adopted from time to time by Landlord for
general application throughout the BLN Office Park.

Any property left in the Leased Premises after the expiration or termination of
the Lease Term shall be deemed to have been abandoned and shall be deemed the
property of Landlord to be disposed of as Landlord sees fit.

38.      HOLDING OVER. Tenant shall not hold over in the Leased Premises, or any
part thereof, after the expiration or termination of the Lease Term. Such
continued occupancy by Tenant shall be at the sufferance of Landlord, and Tenant
shall pay as rent therefor an amount equal to 150% of the amount of Base Rent in
effect for the last period prior to the date of termination or expiration of the
Lease Term, plus additional rent and all other amounts which would have been
payable to the Landlord under this Lease for such additional period had the
Lease remained in effect, adjusted and calculated on a PER DIEM basis. Tenant
shall pay Landlord such amount for each day the Tenant retains possession of the
Leased Premises or any part thereof after such expiration or termination of the
Lease Term. Tenant's obligations with respect to the Leased Premises as a Tenant
at sufferance upon holding over shall be in all respects the same as Tenant's
obligations under the Lease during the Lease Term. At Landlord's option, a
holdover Tenant may be deemed to be a month-to-month tenant whose rent is
subject to adjustment with one month's prior written notice.

39.      DEFAULT. The occurrence of any of the following events shall constitute
         a default by Tenant under this Lease:
         (a) If Tenant shall fail to pay any amounts to be paid by it hereunder,
         including, but not limited to, Base Rent and additional rent, and such
         default shall continue for a period of seven (7) days after Landlord
         has given Tenant written notice of such failure to pay; or

         (b) If Tenant fails to perform or observe any of Tenant's other
         obligations, covenants or agreements herein or hereunder and such
         failure shall continue for a period of twenty (20) days after Landlord
         has given Tenant written notice thereof; or

         (c) If Tenant makes a general assignment for the benefit of creditors,
         or, subject to the rights of a Trustee in Bankruptcy, files, or has
         filed against it, a petition in bankruptcy under the Bankruptcy Reform
         Act of 1978 or under


                                       12
<PAGE>

         any other applicable law of the United States of America or any state
         thereof, consents to the appointment of a trustee or receiver for
         Tenant or for its property, or if Tenant takes any action for the
         purpose of effecting or consenting to any of the foregoing.

         (d) If Tenant holds over after the expiration or termination of this
         Lease.

Upon the occurrence of any of the foregoing defaults, Landlord may, but with no
obligation to do so, immediately, re-enter the Leased Premises and remove all
persons and property therefrom. Landlord shall have the right to keep this Lease
in full force and effect or, at its option, terminate this Lease as to all
future rights of Tenant. Landlord shall comply with notice and other
requirements of Minnesota law as in effect from time to time. Tenant shall be
liable to Landlord for all loss of rents and other damages which Landlord may
incur by reason of such default, including all reasonable attorneys' fees and
expenses incurred in enforcing any of the terms of this Lease. In the event
Landlord re-enters the Leased Premises as set forth herein, and, whether it
elects to keep this Lease in effect or terminate it, Landlord may and shall use
commercially reasonable efforts to re-let the Leased Premises for such rent and
upon such terms as are not unreasonable under the circumstances. In such event,
Tenant also shall be liable for all costs, expenses and damages incurred or
sustained by Landlord in re-letting the Leased Premises, including, without
limitation, deficiency in rent, attorneys' fees, expenses of placing the Leased
Premises in first class rentable condition, brokerage fees, tenant allowances,
improvements or payment of any other tenant inducement. If Tenant has breached
this Lease by failing to pay all rent due hereunder during the initial term
hereof, then Tenant shall be liable to Landlord as an element of Landlord's
damages for the unamortized portion of Landlord's up-front costs in entering
into this Lease, including, but not limited to, leasehold improvements, leasing
commissions and rent abatement. For example, if this Lease is for five years and
Tenant vacates and quits paying rent after three years, and if Landlord had
costs of $50,000 (i.e., $15,000 leasing commission, $25,000 build-out and
$10,000 rent concessions), then Tenant would owe Landlord $20,000 (40% of
$50,000) to reimburse Landlord for the unamortized portion of its up-front
costs. This amount is due irrespective of whether Landlord is successful in
reletting the premises for the balance of the initial term. Landlord shall have
the right to commence one or more actions to enforce the terms hereof, and the
commencement and prosecution of one action shall not be deemed a waiver or an
estoppel from commencing one or more actions from time to time in the future.
Provisions contained in this section shall be in addition to and shall not
prevent the enforcement of any claim Landlord may have against Tenant for
anticipatory breach of the unexpired term of this Lease. All rights and remedies
of Landlord under this Lease shall be cumulative and shall not be exclusive of
any other rights and remedies provided to Landlord under applicable law.

The occurrence of any of the following events shall constitute a default by
Landlord under this Lease: if Landlord fails to perform any of its obligations
under this Lease within thirty (30) days after receiving notice from Tenant
specifying the nature and extent of such failure; provided, however, if the
obligation shall not be reasonably curable within such thirty (30) day period,
the time for cure shall be extended so long as Landlord shall continue to use
reasonable efforts to effect a cure.

40.      RIGHT TO CURE DEFAULTS. If Tenant defaults in the observance or
performance of any of Tenant's covenants, agreements or obligations hereunder
wherein the default can be cured by the expenditure of money, Landlord may, but
without obligation and without limiting any other remedies which it may have by
reason of such default, cure the default, charge the cost thereof to Tenant and
Tenant shall pay the same forthwith upon demand. If Landlord is required to
commence a legal action to recover such sums from the Tenant, Landlord shall
also have the right to recover all interest costs and attorneys' fees in
connection with such litigation.

41.      QUIET  ENJOYMENT.  So long as the  Tenant  complies  with the terms and
conditions  hereof,  it shall be entitled to the peaceable and quiet enjoyment
of the Leased Premises.

42.      FORCE MAJEURE. Any prevention, delay or stoppage of work to be
performed by Landlord or Tenant which is due to strikes, labor disputes,

therefor, acts of God, governmental restrictions or regulations or controls,

other casualty, or other causes beyond the reasonable control of the party

43.      SECURITY DEPOSIT. Tenant agrees to deposit with Landlord a security
deposit in the amount of $11,699.58 upon execution of the Lease, which shall be
held by Landlord as security for Tenant's faithful performance of its
obligations hereunder. Landlord and Tenant agree that the security deposit may
be commingled with funds of Landlord and Landlord shall have no obligation or
liability for payment of interest on such deposit. Tenant shall not pledge,
mortgage, assign, transfer or encumber the security deposit without the prior
written consent of Landlord, and any attempt by Tenant to do so shall be void as
to Landlord's rights. If Tenant fails to pay any rent or other amount due
hereunder or fails to perform any of the other terms hereof, within the
applicable cure period Landlord may appropriate and apply all or any portion of
the security deposit to cure any such default by Tenant hereunder or to
reimburse Landlord for any loss or damage sustained by Landlord as a result of
Tenant's default or breach. Landlord may use the security deposit without
prejudice to any other remedy which it may have. If Landlord so uses any of the
security deposit, Tenant shall, within ten (10) days after written demand by
Landlord, restore the security deposit to the full amount originally deposited.
Tenant's failure to do so shall constitute an event of default hereunder. Within
thirty (30) days after the termination or expiration of this Lease and the
vacation of the Premises by Tenant, Landlord shall account for the security
deposit to Tenant and return any portion which is due or owing. Landlord may
deliver the security deposit to the purchaser of Landlord's interest in the BLN
Office Park and, if it does so, shall be relieved of any further liability to
Tenant for the return of said deposit.

44.      BROKERS. Landlord and Tenant each represent and warrant to the other
that they have dealt with and only with the real estate brokers/agents named on
EXHIBIT E hereto. Landlord and Tenant hereby agree to indemnify, defend and hold
the other harmless from any claims for real estate brokerage or leasing
commissions or other suits of any kind by real estate brokers or representatives
in connection with or arising out of this Lease and the negotiations leading up
to the execution of this Lease.

45.      USE OF THE TERMS "LANDLORD" AND "TENANT." The terms "Landlord" and

cases where there is more than one Landlord or Tenant, and the necessary
grammatical changes required to make the provisions hereof apply to
corporations, partnerships or individuals, men or women, shall in all cases be
assumed as though in each case fully expressed. In addition, where relevant in
this Lease and especially in connection with the provisions of this Lease
relating to personal injury, limitation of liability, indemnification, property
damage and insurance, "Landlord" shall mean Landlord, its respective employees,
agents, invitees, licensees, customers, clients, partners and shareholders, and
"Tenant" shall mean its employees, agents, invitees, licensees, customers,
clients, family members, guests, trespassers, partners and shareholders.

46.      LANDLORD'S CONSENT. Unless it is expressly stated herein that, as to
any particular required consent, Landlord's consent shall not be unreasonably
withheld, Landlord's consent need be given only at Landlord's sole discretion.

47.      INTEREST ON AMOUNTS DUE LANDLORD. Any installment of Base Rent,
additional rent or other charges to be paid by Tenant under the provisions of
this Lease which shall not be promptly paid when due shall bear interest at the
rate of 15% per annum from the date when the same is due until the same shall be
paid, but, if such rate exceeds the maximum rate permitted by law, such interest
rate shall be reduced to the highest rate allowed by law under such
circumstances.

48.      EXECUTION BY LANDLORD. Submission of this instrument to Tenant or
Tenant's agents or attorneys for examination or signature does not constitute or
imply an offer to lease, reservation of space or option to lease, and this Lease
shall have no binding legal effect until execution hereof by both Landlord and
Tenant.

49.      CONTINUANCE OF AGREEMENT. This Agreement shall be binding upon and
inure for the benefit of the parties hereto and subject to the restrictions and
limitations herein contained, their respective heirs, successors and assigns.

50.      SEVERABILITY. The provisions of this Lease are expressly severable, and

impair the enforceability of any other provision or provisions.

attached exhibits or riders are included herein and by reference made a part

                           (a) Base Rent for the Subject ROFO Space shall be
                           payable at the Market Rate specified in Landlord's
                           ROFO Notice; and (b) Tenant's Contribution to
                           Operating Costs shall be adjusted appropriately to
                           take into account the number of rentable square feet
                           in the Subject ROFO Space, and the Contribution to
                           Operating Costs shall be payable at the same rate per
                           rentable square foot as payable for the Leased
                           Premises and subject to the same adjustments as
                           provided in the Lease.

         If Tenant fails to timely exercise the ROFO Right, Landlord shall be
         free to lease the Subject ROFO Space on any terms, and Tenant shall
         have no further rights with respect to such space. The ROFO Right shall
         continue during the ROFO Period as to any remaining ROFO Space on which
         such right has not terminated.

                  c. Tenant's right to exercise the ROFO Right is subject to the
                  condition that, at the time the Tenant delivers its written
                  notice of exercise, Tenant is not in default under any of the
                  terms or conditions of the Lease. Further, the ROFO Right
                  shall automatically terminate upon the earliest to occur of
                  (1) the expiration or termination of the Lease; (2) the
                  termination of Tenant's right to possession of the Premises;
                  (3) the assignment of the Lease by Tenant or the sublease by
                  Tenant of all or any part of the Leased Premises; or (4) the
                  expiration of the ROFO Period.

                  d. Space shall be deemed to become "available" when the
                  existing lease relating to such space, if any, has terminated,
                  whether by expiration of the term of such lease (including any
                  renewals or extensions thereof) or otherwise, and no other
                  party with a prior option or right to lease such space has
                  exercised the same. Notwithstanding anything to the contrary
                  contained herein, the ROFO Right shall exclude and shall be
                  subject to : (1) all leases or letters of intent existing as
                  of the date of this Lease or entered into after Tenant fails
                  to exercise the ROFO Right (including, without limitation, all
                  renewal, extension, expansion, first refusal, first offer or
                  other options or rights thereunder, all leases or amendments
                  pursuant thereto, and all assignments thereof or subleases
                  thereunder); and (2) all renewals or extensions of any leases
                  existing as of the date of this Lease or entered into after
                  Tenant fails to exercise the ROFO Right, whether pursuant to
                  an option or right in such lease or an agreement hereinafter
                  entered into with Landlord.

                  e. Within ten (10) days after written request by Landlord,
                  Tenant shall execute and deliver an instrument in form
                  reasonably satisfactory to Landlord confirming any exercise or
                  termination of the ROFO Right.
