         delivery thereof to the aforesaid Land, and all fixtures (the
         "Fixtures") and articles of personal property (the "Tangible

         contained in and used in connection with the aforesaid Land and
         Improvements including, but not limited to, all furniture, furnishings,

         Improvements, the Fixtures and Tangible Personalty may be collectively
         referred to as the "Premises").

         TO HAVE AND HOLD the same, together with all privileges, hereditaments,
easements and appurtenances thereunto belonging, subject to the Permitted Liens
(as defined in the hereinafter described Credit Agreement) and Permitted
Encumbrances (hereinafter defined), to the Agent and the Agent's successors and

<PAGE>   4

full, this Mortgage shall cease, determine and be void, otherwise, it shall
remain in full force and virtue.

         And, as additional security for said Indebtedness, the Mortgagor hereby
assigns to the Agent all the security deposits, rents, issues, profits and
revenues of the Premises from time to time accruing, excluding any and all
medicare payments (the "Rents and Profits"), reserving only the right to the
Mortgagor to collect and apply the same as Mortgagor chooses as long as there
shall exist no Event of Default (as defined in Article III), and subject further
to the provisions of Article VII below.

         As additional collateral and further security for the Indebtedness, the
Mortgagor does hereby assign and grants to the Agent a security interest in all
of the right, title and the interest of the Mortgagor in and to any and all
insurance policies and proceeds thereof and any and all leases (including
equipment leases), rental agreements, sales contracts, management contracts,
franchise agreements, construction contracts, architects' contracts, technical
services agreements, or other contracts, licenses and permits to the extent now
or hereafter affecting the Premises (the "Intangible Personalty") or any part
thereof, and the Mortgagor agrees to execute and deliver to the Agent such
additional instruments, in form and substance reasonably satisfactory to the
Agent, as may hereafter be reasonably requested by the Agent to evidence and
confirm said assignment; provided, however, that acceptance of any such
assignment shall not be construed as a consent by the Agent to any lease, rental
agreement, management contract, franchise agreement, construction contract,
technical services agreement or other contract, license or permit, or to impose
upon the Agent any obligation with respect thereto. Notwithstanding the
foregoing provisions, such assignment and grant of security interest contained
herein shall not extend to, and the Intangible Personalty shall not include, any
personalty which is now or hereafter held by the Mortgagor as licensee, lessee
or otherwise, to the extent that (a) such personalty is not assignable or
capable of being encumbered as a matter of law or under the terms of the
license, lease or other agreement applicable thereto (but solely to the extent
that any such restriction shall be enforceable under applicable law), without
the consent of the licensor or lessor thereof or other applicable party thereto
and (b) such consent has not been obtained; provided, however, that the
foregoing assignment and grant of security interest shall extend to, and the
Intangible Personalty shall include, any and all proceeds of such personalty to
the extent that the assignment or encumbering of such proceeds is not so
restricted under the terms of the license, lease or other agreement applicable
thereto.

         All the Tangible Personalty which comprise a part of the Premises
shall, as far as permitted by law, be deemed to be affixed to the aforesaid Land
and conveyed therewith. Mortgagor hereby grants a security interest as to the
balance of the Tangible Personalty and the Intangible Personalty, and this
Mortgage shall be considered to be a security agreement which creates a security
interest in such items for the benefit of the Agent. In that regard, the
Mortgagor grants to the Agent all of the rights and remedies of a secured party
under the laws of the state in which the Premises are located.

         The Premises, the Rents and Profits and the Intangible Property may be
collectively referred to hereinafter as the "Mortgaged Property".

         The Mortgagor and the Agent covenant, represent and agree as follows:


                                       4
<PAGE>   5

                                    ARTICLE I

                              Indebtedness Secured

         1.1 Obligations Secured.

         The obligations secured by this Mortgage are the result of the
$115,000,000 credit facility established pursuant to the terms of the Credit
Agreement dated March 24, 2000 among Mortgagor, as borrower, each of the
guarantors party thereto (individually, a "Guarantor" and collectively, the
"Guarantors"), the Lenders party thereto and the Agent (as amended from time to
time, the "Credit Agreement") and evidenced by (a) those revolving loan
promissory notes of the Mortgagor (as referenced and defined in the Credit
Agreement, as amended, modified, supplemented, extended, renewed or replaced
from time to time, the "Revolving Notes"), (b) those letters of credit for the
account of the Mortgagor (as referenced in the Credit Agreement, the "Letters of
Credit"), (c) those Tranche A term promissory notes made by Mortgagor (as such
note or notes are referenced and defined in the Credit Agreement, as amended,
extended, renewed or replaced from time to time, the "Tranche A Term Notes") and
(d) those Tranche B term promissory notes made by Mortgagor (as such note or
notes are referenced and defined in the Credit Agreement, as amended, extended,
renewed or replaced from time to time, the "Tranche B Term Notes"). The
Revolving Notes, the Tranche A Term Notes and the Tranche B Term Notes are
hereinafter collectively referred to as the "Notes", and the loans and
extensions of credit under the Credit Agreement may be referred to as the
"Loans"). This Mortgage is given to secure the payment and performance of all
indebtedness and other obligations now or hereafter owing under the Notes, the
Letters of Credit, the Credit Agreement, this Mortgage and the other Credit
Documents from the Mortgagor to any Lender or Agent, howsoever evidenced,
created, incurred or acquired, whether primary, secondary, direct, contingent,
or joint and several, including without limitation, any liability arising under
Hedging Agreements (as defined in the Credit Agreement) if and to the extent
agreed to by a Credit Party in the documentation evidencing same and all
obligations and liabilities incurred in connection with the collection and
enforcement of the foregoing (collectively, the "Indebtedness").

         1.2 Amount Secured. This Mortgage is intended to secure all present and
future loan disbursements made by the Agent under the Credit Documents, and all
other sums from time to time owing to the Agent by the Credit Parties under the
Credit Documents. Notwithstanding anything to the contrary herein, enforcement
of this Mortgage in Minnesota is limited to the debt amount of $16,000,000.00
under Chapter 287 of Minnesota Statutes, plus additional amounts for accrued
interest and advances by the Agent or Lenders in protection of the Premises and
which is not subject to Minnesota mortgage registry tax.

         1.3 Maturity Date. The latest obligation secured by this Mortgage
matures on December 31, 2005 (the "Maturity Date").

                                   ARTICLE II

              Mortgagor's Covenants, Representations and Agreements

         2.1 Title to Property. The Mortgagor represents and warrants to the
Agent (i) that it is seized of the Land, the Improvements (and any fixtures) and
the Tangible Personalty in fee to the

                                       5
<PAGE>   6

extent such Tangible Personalty does not constitute fixtures and has the right
to encumber and convey the same, (ii) as of the date hereof, that title to such
property is free and clear of all liens and encumbrances except for the
Permitted Liens and title to all such other property is free and clear of all
encumbrances except for the matters shown on the title commitment for the
Premises delivered to the Agent (the "Permitted Encumbrances"), and (iii) that
it will warrant and defend the title to such property except for the Permitted
Encumbrances and Permitted Liens against the claims of all Persons. As to the
balance of the Premises, the Rents and Profits and the Intangible Personalty,
the Mortgagor represents and warrants that it has title to such property, that
it has the right to encumber and convey such property and that it will warrant
and defend such property against the claims of all Persons subject to the
Permitted Encumbrances and the Permitted Liens against the claims of all
persons.

         2.2 Taxes and Fees. The Mortgagor will pay when due all taxes, general
and special assessments, insurance premiums, permit fees, inspection fees, user
fees, license fees, water and sewer charges, franchise fees and equipment rents
and any other charges or fees against it or the Premises as required by the
terms and conditions of Section 7.5 and 7.6 respectively, of the Credit
Agreement (and the Mortgagor, upon request of the Agent, will submit to the
Agent receipts evidencing said payments).

         2.3 Reimbursement. Subject to Mortgagor's right to contest as set forth
in the Credit Agreement, the Mortgagor agrees that if it shall fail to pay on or
before the date that the same become delinquent any tax, assessment or charge
levied or assessed against the Premises or any utility charge, whether public or
private, or any insurance premium, or if it shall fail to procure the insurance
coverage and the delivery of the insurance certificates required hereunder, or
if it shall fail to pay any other charge or fee described in Sections 2.2, 2.3
or 2.6 hereof, then the Agent, at its option, may pay or procure the same and
will give the Mortgagor prompt notice of any such expenditures. The Mortgagor
will reimburse the Agent upon demand for any sums of money paid by the Agent
pursuant to this Section, together with interest on each such payment at the
default rate of interest provided in Section 3.1 of the Credit Agreement for
Loans, and all such sums and interest thereon shall be secured hereby.

         2.4 Additional Documents. The Mortgagor agrees to execute and deliver
to the Agent, concurrently with the execution of this Mortgage and upon the
request of the Agent from time to time hereafter, all financing statements and
other documents reasonably required to perfect and maintain the security
interest created hereby. The Mortgagor hereby irrevocably (as long as the Loans
or Letters of Credit remain outstanding or the Commitments have not been
terminated) makes, constitutes and appoints the Agent as the true and lawful
attorney of the Mortgagor (such appointment being coupled with an interest) to
sign the name of the Mortgagor (after the Mortgagor has failed or refused to
timely execute such documents upon request of the Agent) on any financing
statement, continuation of financing statement or similar document required to
perfect or continue such security interests but only in the event the Mortgagor
refuses to do so after receipt of written notice.

         2.5 Sale or Encumbrance. Except as otherwise permitted by the Credit
Agreement, the Mortgagor will not sell, encumber or otherwise dispose of any of
the Tangible Personalty except to incorporate such into the Improvements or
replace such with goods of quality and value at least equal to that replaced.
Provided, however, in the event the Mortgagor sells or


                                       6
<PAGE>   7

otherwise disposes of any of the Tangible Personalty, the Agent's security
interest in the proceeds of the Tangible Personalty shall continue pursuant to
this Mortgage.

         2.6 Fees and Expenses. The Mortgagor will promptly pay upon demand any
and all reasonable costs and expenses of the Agent, (a) as required under
Section 11.5 of the Credit Agreement and (b) as reasonably necessary to protect
the Premises, the Rents and Profits or the Intangible Personalty or to exercise
any rights or remedies under this Mortgage or with respect to the Premises,
Rents and Profits or the Intangible Personalty. All of the foregoing costs and
expenses shall be secured hereby.

         2.7 Leases and Other Agreements. Without first obtaining on each
occasion the written approval of the Agent, which approval shall not be
unreasonably withheld, the Mortgagor shall not, except as permitted by the
Credit Agreement, enter into, cancel, surrender or materially modify or permit
the cancellation of any material lease (including any equipment lease), rental
agreement, management contract, franchise agreement, construction contract,
technical services agreement or other material contract, license or permit now
or hereafter affecting the Premises, or materially modify any of said
instruments, or accept or permit to be made, any prepayment (more than one
month) of any installment of rent or fees thereunder. Certified copies of each
such approved material lease or other material agreement not previously
delivered to the Agent shall be submitted to the Agent as soon as possible. The
Mortgagor shall faithfully keep and perform, or cause to be kept and performed,
in all material respects, all of the covenants, conditions, and agreements
contained in each of said agreements, now or hereafter existing, on the part of
the Mortgagor to be kept and performed (including performance of all covenants
to be performed under any and all leases of the Premises or any part thereof)
and shall at all times use commercially reasonable efforts to enforce, with
respect to each other party to said agreements, all obligations, covenants and
agreements by such other party to be performed thereunder.

         2.8 Maintenance of Premises. Except as provided otherwise in the Credit
Agreement, the Mortgagor will abstain from and will not permit the commission of
waste in or about the Premises and will maintain, or cause to be maintained, the
Premises in reasonable condition and repair, ordinary wear and tear, casualty,
condemnation and obsolescence excepted.

         2.9 Insurance. The Mortgagor shall maintain insurance for the Premises
as set forth in Section 7.6 of the Credit Agreement. In addition to the
requirements set forth in Section 7.6 of the Credit Agreement, if any part of
the Improvements is located in an area having "special flood hazards" as defined
in the Federal Flood Disaster Protection Act of 1973, a flood insurance policy
as may be required by law naming the Agent as mortgagee must be submitted to the
Agent. The policy must be in such amount, covering such risks and liabilities
and with such deductibles or self-insurance retentions as are in accordance with
normal industry practice.

         2.10 Eminent Domain. Subject to the provisions of the Credit Agreement,
the Mortgagor assigns to the Agent any proceeds or awards which may become due
by reason of any condemnation or other taking for public use of the whole or any
part of the Premises or any rights appurtenant thereto to which the Mortgagor
agrees to execute such further assignments and agreements as may be reasonably
required by the Agent to assure the effectiveness of this Section. In the event
any Governmental Authority shall require or commence any proceedings for the
demolition of any buildings or structures comprising a part of the Premises, or
shall



                                       7
<PAGE>   8


commence any proceedings to condemn or otherwise take pursuant to the
power of eminent domain a material portion of the Premises, the Mortgagor shall
promptly notify the Agent of such requirements or commencement of proceeding
(for demolition, condemnation of other taking).

         2.11 Releases and Waivers. The Mortgagor agrees that no release by the
Agent of any portion of the Premises, the Rents and Profits or the Intangible
Personalty, no subordination of Lien, no forbearance on the part of the Agent to
collect on the Loans, or Letters of Credit or any part thereof, no waiver of any
right granted or remedy available to the Agent and no action taken or not taken
by the Agent shall, except to the extent expressly released, in any way have the
effect of releasing the Mortgagor from full responsibility to the Lender's and
the Agent for the complete discharge of each and every of the Mortgagor's
obligations hereunder.

         2.12 Transfer of Premises. Except as otherwise permitted in the Credit
Agreement, the Mortgagor covenants and agrees with the Agent that the Mortgagor
shall not sell, transfer, convey, mortgage, encumber or otherwise dispose of the
Premises, the Rents Sand Profits or the Intangible Personalty or any part
thereof or any interest therein or engage in subordinate financing with respect
thereto during the term of this Mortgage without the prior written consent of
the Agent.

         2.13 Compliance with Law. Except as otherwise permitted in the Credit
Agreement, the Mortgagor will comply with all applicable statutes, regulations
and orders of, and all applicable restrictions imposed by, all governmental
authorities in respect of the ownership of the Premises (including applicable
statutes, regulations, orders and restrictions relating to environmental
standards and controls).

         2.14 Inspection. Except as otherwise permitted in the Credit Agreement,
the Mortgagor will permit the Agent, or its agents, at all reasonable times and
with advance prior notice to enter and pass through or over the Premises for the
purpose of inspecting same; provided, however, prior to an Event of Default
inspections shall be at reasonable times during the Mortgagor's normal business
hours.

         2.15 Security Agreement and Fixture Filing.

         (a)  Insofar as the fixtures and articles of personal property either
referred to or described in this Mortgage are in any way connected with the use
and enjoyment of the Premises, this Mortgage is hereby made and declared to be a
security agreement (and Mortgagor hereby grants Agent a security interest in),
encumbering each and every item of personal property included herein, in
compliance with the provisions of the Uniform Commercial Code as enacted in the
state where the Premises are located. A financing statement or statements
reciting this Mortgage to be a security agreement, affecting all of said
personal property aforementioned, shall be executed by the Mortgagor and the
Agent and appropriately filed. The remedies for, any violation of the covenants,
terms and condition of the security agreement herein contained shall be (i) as
prescribed herein, (ii) as prescribed by general law, (iii) as prescribed by the
specific statutory consequences now or hereafter enacted and specified in said
Uniform Commercial Code, or (iv) as prescribed by the specific procedures and
remedies available pursuant to a foreclosure of real estate, all at Agent's sole
election. The Mortgagor and the Agent agree that



                                       8
<PAGE>   9


the filing of such financing statement(s) in the records normally having to do
with personal property shall never be construed as in anywise derogating from or
impairing this declaration and hereby stated intention of the Mortgagor and the
Agent that everything used in connection with the production of income from the
Premises or adapted for use therein or which is described or reflected in this
Mortgage is, and at all times and for all purposes and in all proceedings both
legal or equitable shall be, regarded as part of the real estate irrespective of
whether (a) any such item is physically attached to the improvements, (b) serial
numbers are used for the better identification of certain items capable of being
thus identified in a recital contained herein, or (c) any such item is referred
to or reflected in any such financing statement(s) so filed at any time.
Similarly, the mention in any such financing statement(s) of the rights in and
to (aa) the proceeds of any fire or hazard insurance policy of (bb) any award in
eminent domain proceedings for a taking or for loss of value or (cc) the
Mortgagor's interest as lessor in any present or future lease or rights to
income growing out of the use or occupancy of the Premises, whether pursuant to
lease or otherwise, shall never be construed as in anywise altering any of the
rights of the Mortgagor or the Agent as determined by this instrument or
impugning the priority of the Agent's lien granted hereby or by any other
recorded document, but such mention in such financing statement(s) is declared
to be for the protection of the Agent in the event any court shall at any time
hold with respect to the foregoing (aa) or (bb) or (cc), that notice of the
Agent's priority of interest to be effective against a particular class of
persons, must be filed in the Uniform Commercial Code records.

         (b) The Mortgagor warrants that the names of the "Debtor" and the
"Secured Party" (which are the Mortgagor and the Agent, respectively), the
address of the "Secured Party" from which information concerning the security
interest may be obtained, and the address of "Debtor", are as set forth in
Section 6.2, hereof; and a statement indicating the types, or describing the
items, of collateral is set forth hereinabove. The location of the collateral
which is Tangible Personally is upon the Land. The Mortgagor agrees to furnish
the Agent with notice of any change in the name, identity, corporate structure,
residence, principal place of business or mailing address of the Mortgagor
within ten (10) days of the effective date of any such change and the Mortgagor
will promptly execute any financing statements or other instruments deemed
necessary by the Agent to prevent any filed financing statement from becoming
misleading or losing its perfected status. The federal taxpayer identification
number of the Mortgagor is 13-4018241. The name of the record owner of the
Premises is the Mortgagor. This document covers goods which are, or are to
become, fixtures, and this Mortgage is to be a Fixture filing to be filed for
record in the public real estate records.

                                   ARTICLE III

                                Events of Default

         An Event of Default shall exist under the terms of this Mortgage upon
the existence of an Event of Default under the terms of the Credit Agreement.

         4.1 Acceleration of Secured Indebtedness; Foreclosure. Upon the
occurrence and during the continuance of an Event of Default, the entire balance
of the Loans and Letters of Credit and any other obligations due under the
Credit Documents, including all accrued interest, shall, at the option of the
Agent, become immediately due and payable. Upon failure to pay the Credit Party
Obligations or reimburse any other amounts due under the Credit Documents in
full at any stated or accelerated maturity and in addition to all other remedies
available to the Agent at law or in equity, the Agent may foreclose the lien of
this Mortgage by judicial or nonjudicial proceeding in a manner permitted by
applicable law. The Mortgagor hereby waives any statutory right of redemption in
connection with such foreclosure proceeding.

         4.2 Power of Sale. Upon the occurrence of any Event of Default
hereunder, the Agent may (and is hereby authorized and empowered to) foreclose
this Mortgage by action or advertisement, pursuant to the statutes of the State
of Minnesota in such case made and provided, power being expressly granted to
sell the Mortgaged Property, either in one parcel or separate lots and parcels,
at public auction and convey the same to the purchaser in fee simple and, out of
the proceeds arising from such sale, to pay all Credit Party Obligations with
interest, and all legal costs and damages of such foreclosure and the maximum
attorney's fees permitted by law, which costs, charges and fees the Mortgagor
agrees to pay.

         4.3 Proceeds of Sale. Following a foreclosure sale, the proceeds of
such sale shall, subject to applicable law, be applied in accordance with
Section 3.15(b) of the Security Agreement, with the balance, if any, to be paid
to persons entitled thereto by law.

                                    ARTICLE V

                   Additional Rights and Remedies of the Agent

         5.1 Rights Upon an Event of Default. Upon the occurrence and during the
continuance of an Event of Default, the Agent, immediately and without
additional notice and without liability therefor to the Mortgagor, except for
gross negligence, willful misconduct or unlawful conduct, may do or cause to be
done any or all of the following to the extent permitted by applicable law: (a)
take physical possession of the Premises; (b) exercise its right to collect the
Rents and Profits; (c) enter into contracts for the completion, repair and
maintenance of the Improvements thereon; (d) expend Loan funds and any rents,
income and profits derived from the Premises for the payment of any taxes,
insurance premiums, assessments and charges for completion, repair and
maintenance of the Improvements, preservation of the lien of this Mortgage and
satisfaction and fulfillment of any liabilities or obligations of the Mortgagor
arising out of or in any way connected with the Premises whether or not such
liabilities and obligations in any way affect, or may affect, the lien of this
Mortgage; (e) enter into leases demising the Premises or any part thereof, (f)
take such steps to protect and enforce the specific performance of any covenant,
condition or agreement in the Notes, the Letters of Credit, this Mortgage, the
Credit Agreement or the other Credit Documents, or to aid the execution of any
power herein granted; (g) collect rents; and (h) generally, supervise, manage,
and contract with


                                       10

<PAGE>   11

reference to the Premises as if the Agent were equitable owner of the Premises.
Notwithstanding the occurrence of an Event of Default or acceleration of the
Loans and in accordance with the Credit Agreement, the Agent shall continue to
have the right to pay money, whether or not Loan funds, for the purposes
described in Sections 2.2, 2.6 and 2.8 hereof, and all such sums and interest
thereon shall be secured hereby. The Mortgagor also agrees that any of the
foregoing rights and remedies of the Agent may be exercised at any time
independently of the exercise of any other such rights and remedies, and the
Agent may continue to exercise any or all such rights and remedies until the
Event(s) of Default are cured or waived with the consent of the Required
Lenders' or the Lenders (as required by the Credit Agreement) or until
foreclosure and the conveyance of the Premises or until the Indebtedness secured
hereby is satisfied or paid in full and the commitments are terminated.

         5.2 Appointment of Receiver. Upon the occurrence of an Event of
Default, the Agent shall be entitled as a matter of right, without additional
notice and without regard to the adequacy of any security for the indebtedness
secured hereby, whether the same shall then be occupied as a homestead or not,
and without regard to waste or the solvency of any party bound for its payment,
and without giving bond, to make application for, and the Mortgagor hereby
consents to, the appointment of a receiver to take possession of and to operate
the Premises, whether or not foreclosure proceedings have been commenced, and
whether or not a foreclosure sale has occurred, and to collect the rents,
issues, profits, and income thereof, all expenses of which shall be added to the
Credit Party Obligations and secured hereby. The receiver shall have all the
rights and powers provided for under the laws of the state in which the Premises
are located, including without limitation, the rights of a receiver under Minn.
Stat. Section 576.01 as amended, and including without limitation, the power to
execute leases for terms which extend beyond the receivership, and the power to
collect the rents, sales proceeds, issues, profits and proceeds of the Premises
during the pendency of such foreclosure suit, as well as during any further
times when the Mortgagor, its successors or assigns, except for the intervention
of such receiver, would be entitled to collect such rents, sales proceeds,
issues, proceeds and profits, and all other powers which may be necessary or are
usual in such cases for the protection, possession, control, management and
operation of the Premises during the whole of said period and to apply the
rents, issues, income and profits to the payment of the expenses enumerated in
Minn. Stat. Section 576.01, Sub. 2, in the priority mentioned therein and as
provided below in this Mortgage. Notwithstanding the appointment of any
receiver, trustee or other custodian, the Agent shall be entitled, to retain
possession and control of any cash or other instruments, at the time held by or
payable or deliverable under the terms of the Mortgage to the Agent to the
fullest extent permitted by law.

         5.3 Waivers. No waiver of any Event of Default shall at any time
thereafter be held to be a waiver of any rights of the Agent stated anywhere in
the Notes, the Letters of Credit, this Mortgage, the Credit Agreement or any of
the other Credit Documents, nor shall any waiver of a prior Event of Default
operate to waive any subsequent Event(s) of Default. All remedies provided in
this Mortgage, the Notes, the Letters of Credit, the Credit Agreement or any of
the other Credit Documents are cumulative and may, at the election of the Agent,
be exercised alternatively, successively, or in any manner and are in addition
to any other rights provided by law.

         5.4 Delivery of Possession After Foreclosure.

         In the event there is a foreclosure sale hereunder and at the time of
such sale, the Mortgagor or the Mortgagor's heirs, devises, representatives,
successors or assigns are occupying or using the Premises, or any part thereof,
each and all immediately shall become the tenant of the purchaser at such sale,
which tenancy shall be a tenancy from day to day, terminable at the will of
either landlord or tenant, at a reasonable rental per day based upon the value
of the property occupied, such rental to be due daily to the purchaser; and to
the extent permitted by applicable law, the purchaser at such sale,
notwithstanding any language herein apparently to the contrary, shall have the
sole option to demand possession immediately following the sale or to permit the
occupants to remain as tenants at will. In the event the tenant fails to
surrender possession of said property upon demand, the purchaser shall be
entitled to institute and maintain a summary action for possession of the
property (such as an action for forcible detainer) in any court having
jurisdiction.

         5.5 Marshalling.

         The Mortgagor hereby waives, in the event of foreclosure of this
Mortgage or the enforcement by the Agent of any other rights and remedies
hereunder, any right otherwise available in respect to marshalling of assets
which secure the Loans and Letters of Credit and any other indebtedness secured
hereby or to require the Agent to pursue its remedies against any other such
assets.

         5.6 Restoration of Position.

         In case Agent shall have proceeded to enforce any right under this
Mortgage by foreclosure, sale, entry or otherwise, and such proceedings shall
have been discontinued or abandoned for any reason or shall have been determined
adversely, then, and in every such case, Mortgagor and Agent shall be restored
to this former positions and rights hereunder with respect to the Premises
subject to the lien hereof

         6.5 Conflicting Terms. In the event the terms and conditions of this

         (c) THIS WRITTEN MORTGAGE AND THE OTHER LOAN DOCUMENTS REPRESENT THE
FINAL AGREEMENTS BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF

NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         6.9 WAIVER OF JURY TRIAL. THE AGENT AND THE MORTGAGOR HEREBY WAIVE, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE RIGHT TO A TRIAL BY JURY IN
ANY ACTION OR PROCEEDING BASED UPON, OR RELATED TO, THE SUBJECT MATTER OF THIS
MORTGAGE. THIS WAIVER IS


                                       14
<PAGE>   15

KNOWINGLY, INTENTIONALLY, AND VOLUNTARILY MADE BY THE AGENT AND THE MORTGAGOR,

redemption from any sale made in collecting Indebtedness.

         6.12 Inconsistent Provisions. In the event of any inconsistency between
the provisions of this Mortgage and the provisions of the Credit Agreement, the
Credit Agreement shall control, subject, when applicable, to the laws of the
State of Minnesota regarding foreclosures of mortgages and the appointment of
receivers.

                                   ARTICLE VII

                         Assignment of Rents and Profits

         7.1 Assignment. The Mortgagor does hereby sell, assign and transfer
unto the Agent as additional security for the Credit Party Obligations (subject
to the limitation on the maximum amount of indebtedness set forth herein), all
of the Rents and Profits now due and which may hereafter become due under or by
virtue of any lease, whether written or verbal, or any agreement for the use or
occupancy of the Premises or any portion of the Premises, it being the intention
of this Mortgage to establish, and this is, an absolute and present transfer and
assignment of all such leases and agreements and all of the Rents and Profits
from the Premises unto the Agent and the Mortgagor does hereby appoint
irrevocably the Agent its true and lawful attorney in its name and stead, which
appointment is coupled with an interest, to collect all of said Rents and
Profits; provided, Agent grants the Mortgagor the privilege to collect and
retain such Rents and Profits unless and until an Event of Default exists under
this Mortgage. Upon an Event of Default and whether before or after the
institution of proceedings to sell the Premises or foreclose this Mortgage or
during any period of redemption, and without regard to waste, adequacy of the
security or solvency of the Mortgagor, Agent may revoke, at its option, the
privilege granted Mortgagor hereunder to collect the Rents and Profits of the
Premises, and Agent may, at its option, without notice, in person or by agent,
with or without taking possession of or entering the Premises, with or without
bringing any action or proceeding, or by a receiver duly appointed, give, or
require Mortgagor to give, notice to any or all tenants under any lease




                                       15



<PAGE>   16



authorizing and directing the tenant to pay such Rents and Profits to Agent,
such agent, or receiver as the case may be; collect all of the Rents and
Profits; enforce the payment thereof and exercise all of the rights of the
landlord under any lease and all of the rights of Agent hereunder; enter upon,
take possession of, manage and operate said Premises, or any part thereof;
cancel, enforce or modify any leases, and fix or modify rents, and do any acts
which the Agent deems proper to protect the security hereof

         7.2 Application of Rents and Profits. Notwithstanding anything to the
contrary herein, all Rents and Profits collected by the Agent or any receiver
each month shall be applied as follows:

         (a) to payment of all reasonable fees of the receiver approved by the
court;

         (b) to payment of all tenant security deposits then owing to tenants
under any of the Leases pursuant to the provisions of Minn. Stat. 504.20;

         (c) to payment of all prior or current real estate taxes and special
assessments with respect to the Premises, or if the Mortgage requires periodic
escrow payments for such taxes and assessments, to the escrow payments then due;

         (d) to payment of all premiums then due for the insurance required by
the provisions of the Mortgage, or if the Mortgage requires periodic escrow
payments for such premiums, to the escrow payments then due;

         (e) to payment of expenses incurred for normal maintenance and
operation of the Premises;

         (f) if received prior to any foreclosure sale of the Premises pursuant
to this Mortgage, to the Agent for payment of the Credit Party Obligations
secured by the Mortgage, but no such payment made after the acceleration of the
indebtedness shall affect such acceleration;

         (g) if received during or with respect to the period of redemption
after a foreclosure sale of the Premises pursuant to this Mortgage:

                  (i) if the purchaser at the foreclosure sale is not the Agent,
first to the Agent to the extent of any deficiency of the sale proceeds to repay
the Credit Party Obligations secured by this Mortgage, and second to the
purchaser as a credit to the redemption price, but if the Premises are not
redeemed, then to the purchaser of the Premises pursuant to Minn. Stat. Sections
580.30, 580.23 or 581.10, with any excess to be paid to Mortgagor;

                  (ii) if the purchaser at the foreclosure sale is the Agent, to
the Agent to the extent of any deficiency of the sale proceeds to repay the
Credit Party Obligations secured by the Mortgage and the balance to be retained
by the Agent as a credit to the redemption price, but if the Premises are not
redeemed, then to the Agent, whether or not any such deficiency exists.

         The rights and powers of the Agent under this Assignment and the
application of Rents and Profits under this Section 7.2 shall continue until
expiration of the redemption period from any foreclosure sale, whether or not
any deficiency remains after a foreclosure sale.




                                       16



<PAGE>   17



         7.3 Non-waiver. The entering upon and taking possession of the
Premises, the collection of such Rents and Profits and the application thereof
as aforesaid shall not cure or waive any defaults under this Mortgage or affect
any notice of default or invalidate any act done pursuant to such notice nor in
any way operate to prevent the Agent from pursuing any other remedy which it may
now or hereafter have under the terms of this Mortgage or any other security
given for the Credit Party Obligations nor shall it in any way be deemed to
constitute the Agent a mortgagee-in-possession.

         PROVIDED ALWAYS, and it is the true intent and meaning of the Mortgagor
and the Agent, that if the Mortgagor, its successors and assigns, shall pay or
cause to be paid and discharged unto the Agent, its successors and assigns, the
obligations secured hereby according to the terms of this Mortgage and the
Credit Documents, then this Mortgage shall cease, determine and be void,
otherwise it shall remain in full force and virtue. And it is agreed, by and
between the Mortgagor and the Agent, that the Mortgagor is to hold and enjoy the
said premises until an Event of Default be made in the terms of this Mortgage.
