                 ALTERRA HEALTHCARE CORPORATION AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


(1)      BASIS OF PRESENTATION

         The condensed consolidated balance sheets as of September 30, 1999 and
December 31, 1998, the condensed consolidated statements of operations for the
three and nine months ended September 30, 1999 and 1998 and the condensed
consolidated statements of cash flows for the nine months ended September 30,
1999 and 1998 contained herein include the accounts of Alterra Healthcare
Corporation (the "Company") and its affiliates which are under the common
financial control of the Company. All significant intercompany accounts have
been eliminated in consolidation. In the opinion of management, all adjustments
(consisting only of normal recurring items) necessary for a fair presentation of
such condensed consolidated financial statements have been included. The results
of operations for the nine months ended September 30, 1999 are not necessarily
indicative of the results to be expected for the full fiscal year.

         The condensed consolidated financial statements do not include all
information and footnotes necessary for a complete presentation of financial
position, results of operations, and cash flows in conformity with generally
accepted accounting principles. The accompanying condensed consolidated
financial statements should be read in conjunction with the audited consolidated
financial statements and notes thereto included in the Company's Annual Report
on Form 10-K, for the year ended December 31, 1998.

(2)      ACQUISITIONS

     During the quarter ended September 30, 1999, the Company consummated a
synthetic lease transaction relating to 26 assisted living and
Alzheimer's/dementia care residences that were previously owned and operated by
Manor Care, Inc. and it's affiliates (the "Transaction"). Pursuant to the
Transaction, an affiliate of Key Bank National Association acquired the 26
residences for an aggregate purchase price of approximately $189.1 million
(including closing costs) and simultaneously leased the 26 residences to AHC
Tenant, Inc., a wholly-owned subsidiary of the Company. Mortgage financing for
the acquisition in the amount of $174.5 million was provided by Greenwich
Capital Financial Products and credit enhancement of this financing in the form
of a surety bond was provided by a member of the Zurich Financial Services
Group. The Company's leases of these 26 residences have a term of ten years,
reflect initial rental based on a lease constant of 9.93% and contain an option
to purchase the 26 residences at the end of the lease term for a pre-negotiated
fixed price. For financial accounting purposes, leases for 17 of the residences
will be treated as operating leases and leases for nine residences will be
treated as capital leases. The Company recorded $53.2 million of property and
equipment and $53.2 million of long term obligations upon completion of the
Transaction related to these capital leases. The Company also entered into
leases with Manor Care, Inc. with respect to two additional residences formerly
operated by Manor Care, Inc.

(3)      CUMULATIVE EFFECT OF A CHANGE IN ACCOUNTING PRINCIPLE

         In the first quarter of 1999, the Company adopted the Statement of
Position No. 98-5, "Reporting on the Costs of Start-up Activities." This
Statement provides guidance on the financial reporting of start-up activities
and organization costs. It requires costs of start-up activities and
organization costs to be expensed when incurred. The Company's prior practice
was to capitalize such costs and amortize them over a one year period after
residence opening in the case of start-up costs and five years in the case of
organizational costs. The cumulative effect of the accounting change reflected
in the condensed consolidated statement of operations for the nine months ended
September 30, 1999 was $3.8 million, net of tax.

        (1)   Nine month period ended September 30, 1999 does not total due to
              rounding.

         Shares issuable upon the conversion of convertible subordinated
notes have been excluded from the computation because the effect of their
inclusion would be anti-dilutive.

(5)  RECLASSIFICATIONS

         Certain reclassifications have been made in the 1998 financial
statements to conform with the 1999 financial statement presentation.

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

Overview

         The Company's continued growth has had a significant impact on its
results of operations and accounts for most of the changes in results between
the first nine months of 1999 and 1998. As of September 30, 1999 and 1998, the
Company operated or managed 431 and 336 residences with aggregate capacities of
19,688 and 14,315 residents, respectively. The Company is also constructing or
developing approximately 116 residences with aggregate capacity of 5,400 as of
September 30, 1999.  However, the Company has announced its intention during the
fourth quarter of 1999 to review development projects not yet in construction
and, in light of the competitive environment and tighter capital markets, to
discontinue or defer a substantial portion of these projects. See "-Liquidity
and Capital Resources."  For the nine months ended September 30, 1999, the
Company generated operating revenue of $274.9 million, and realized operating
income of $27.0 million, and net income of $15.1 million prior to the cumulative
effect of a change in accounting.

THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THE THREE MONTHS ENDED
SEPTEMBER  30, 1998

         Residence Service Fees. Residence service fees for the three months
ended September 30, 1999 were $90.6 million representing an increase of $26.1
million, or 40%, from the $64.5 million for the comparable 1998 period.
Substantially all of this increase resulted from the addition of newly
constructed residences and other residences acquired by the Company. The Company
operated 431 and 336 residences at September 30, 1999 and 1998, respectively.

         Management Fees and Other Revenues. Management Fees and other revenues
for the three months ended September 30, 1999 were $9.4 million, an increase of
$7.7 million over the $1.7 million of other revenue for the three months ended
September 30, 1998. The increase is attributable to management fees on a greater
number of residences which were either managed for third parties or for entities
in which the Company held a minority ownership position in the 1999 period
versus the 1998 period. As of September 30, 1999, the Company managed 92 such
residences compared to 61 such residences as of September 30, 1998. Management
fees include charges for transitional services to recruit and train staff,
initial and recurring fees for the use of the Company's Name and branding,
initial and recurring fees for the use of the Company's methodologies, services
for assisting with finance processing, and ongoing management services provided
to operate the residence.

         Residence Operating Expenses. Residence operating expenses for the
three months ended September 30, 1999 increased to $57.5 million from $40.5
million in the three-month period ended September 30, 1998 due to the increased
number of residences operated during the 1999 period. Operating expenses as a
percentage of residence service fees for the three months ended September 30,
1999 and 1998 were 63.4% and 62.7%, respectively. This percentage increase
resulted primarily from increases in labor costs due to increased competition
for personnel. The increase in marginal expenses was also impacted by a slower
lease-up of residences in some markets.

         Lease Expense. Lease expense for the three months ended September 30,
1999 was $18.4 million, compared to $11.9 million in the comparable period in
1998. Such increase was primarily attributable to the utilization of additional
sale/leaseback financing totaling $115.4 million during the twelve-month period
ended September 30, 1999.

         General and Administrative Expense. For the three months ended
September 30, 1999, general and administrative expenses were $9.3 million,
compared to $6.3 million for the comparable 1998 period, representing a decrease
as a percentage of operating revenue to 9.3% in the 1999 period from 9.5% in the
1998 period.

                                       6
<PAGE>   9
The $3.0 million increase in expenses from 1998 was primarily attributable to
salaries, related payroll taxes and employee benefits for additional corporate
personnel retained to support the Company's growth.

         Depreciation and Amortization. Depreciation and amortization for the
three months ended September 30, 1999 was $5.2 million, representing a decrease
of $300,000, or 5.4%, from the $5.5 million of depreciation and amortization for
the comparable 1998 period. This decrease resulted primarily from the
elimination of amortization on pre-opening costs which are now expensed when
they are incurred. This decrease was offset by depreciation of fixed assets on
the larger number of new residences that were owned by the Company during the
three months ended September 30, 1999, versus the comparable period in 1998.

         Interest Expense, Net. Interest expense, net of interest income, was
$9.1 million for the three months ended September 30, 1999, compared to $2.7
million for the comparable period in 1998. Gross interest expense (before
interest capitalization and interest income) for the 1999 period was $12.7
million compared to $8.0 million for the 1998 period, an increase of $4.7
million. This increase is primarily attributable to an increase in the amount of
debt financing used in the 1999 period as compared to the 1998 period. The
Company capitalized $2.2 million of interest expense in the 1999 period compared
to $3.7 million in the comparable 1998 period. This decrease is due primarily to
a decrease in assets under construction financed using general corporate funds
in 1999 compared to 1998. Interest income for the 1999 period was $1.5 million
as compared to $1.6 million for the 1998 period. This decrease was primarily due
to a reduction in average cash and investment balances from 1998 to 1999.

         Lease Income. The Company recorded $7.6 million of lease income on
residences owned or leased by the Company and leased or subleased to
unconsolidated joint ventures in 1999. Lease payment obligations of the
unconsolidated joint venture entities are generally equivalent to the debt
service payable by the Company on the leased residences, and thereby offset
Company costs associated with obtaining and maintaining financing for such
residences.  The Company had no such arrangements in 1998.

         Minority Interest in Losses of Consolidated Subsidiaries. Minority
interest in losses of consolidated subsidiaries for the three months ended
September 30, 1999 was $498,000, representing a decrease of $5.5 million from
$6.0 million for the comparable 1998 period. The decrease was primarily
attributable to the decrease in the number of residences in various stages of
lease-up that were owned by the Company in consolidated joint venture
arrangements during the 1999 period. During the third quarter of 1999, the
Company had an average of 11 residences held in these consolidated joint venture
arrangements compared to an average of 60 residences held in similar joint
venture arrangements during the comparable 1998 period.

         Income Taxes. For the three months ended September 30, 1999, the
Company recorded a reduction in the current income tax provision of $853,000
which was offset by the recognition of a $3.9 million deferred tax obligation
resulting in a current income tax expense of $3.0 million. During the three
months ended September 30, 1998, the Company recorded a current income tax
provision of $4.3 million which was offset by the recognition of $4.9 million of
deferred tax assets resulting in a current income tax benefit of $549,000.

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THE NINE MONTHS ENDED
SEPTEMBER 30, 1998

         Residence Service Fees. Residence service fees for the nine months
ended September 30, 1999 were $252.1 million representing an increase of $87.3
million, or 53%, from the $164.8 million for the comparable 1998 period.
Substantially all of this increase resulted from the addition of newly
constructed residences and other residences acquired by the Company. The Company
operated 431 and 336 residences at September 30, 1999 and 1998, respectively.

         Management Fees and Other Revenues. Management Fees and other revenues
for the nine months ended September 30, 1999 were $22.8 million, an increase of
$19.7 million over the $3.1 million of other revenue for the nine months ended
September 30, 1998. The increase is attributable to management fees on a greater
number of residences which were either managed for third parties or for entities
in which the Company held a minority ownership position in the 1999 period
versus the 1998 period. As of September 30, 1999, the Company managed 92 such
residences compared to 61 such residences as of September 30, 1998. Management
fees include charges for transitional services to recruit and train staff,
initial and recurring fees for use of the Company's name and branding, initial
and recurring fees for the use of the Company's methodologies, services for
assisting with finance processing, and ongoing management services provided to
operate the residence. The increase in other revenue was also impacted by $3.0
million of development fees recognized in the first nine months of 1999 in
connection with development activities conducted by the Company on behalf of
third parties.

         Residence Operating Expenses. Residence operating expenses for the nine
months ended September 30, 1999 increased to $157.1 million from $104.1 million
in the nine month period ended September 30, 1998 due to the increased number of
residences operated during the 1999 period. Operating expenses as a percentage
of resident service fees for the nine months ended September 30, 1999 and 1998
were 62.3% and 63.1%, respectively.

         Lease Expense. Lease expense for the nine months ended September 30,
1999 was $48.8 million, compared to $30.9 million in the comparable period in
1998. Such increase was primarily attributable to the utilization of additional
sale/leaseback financing totaling $115.4 million during the twelve-month period
ended September 30, 1999.

         General and Administrative Expense. For the nine months ended September
30, 1999, general and administrative expenses before costs related to the $1.8
million write-off of existing signage and other expenses associated with the
name change from Alternative Living Services, Inc. to Alterra Healthcare
Corporation were $26.4 million, compared to $16.4 million for the comparable
1998 period, representing a decrease as a percentage of operating revenue to
9.6% in the 1999 period from 9.8% in the 1998 period. The $10.0 million increase
in expenses from 1998 was primarily attributable to salaries, related payroll
taxes and employee benefits for additional corporate personnel retained to
support the Company's growth.

         Depreciation and Amortization. Depreciation and amortization for the
nine months ended September 30, 1999 was $13.8 million, representing an increase
of $600,000, or 4.6%, from the $13.2 million of depreciation and amortization
for the comparable 1998 period. This increase resulted primarily from
depreciation of fixed assets on the larger number of new residences that were
owned by the Company during the nine months ended September 30, 1999, versus the
comparable period in 1998. This increase was offset by the elimination of
amortization on pre-opening costs which are now expensed when they are incurred.

         Interest Expense, Net. Interest expense, net of interest income, was
$23.1 million for the nine months ended September 30, 1999, compared to $5.3
million for the comparable period in 1998. Gross

                                       8

interest expense (before interest capitalization and interest income) for the
1999 period was $33.8 million compared to $20.8 million for the 1998 period, an
increase of $13.0 million. This increase is primarily attributable to an
increase in the amount of debt financing used in the 1999 period as compared to
the 1998 period. The Company capitalized $7.4 million of interest expense in the
1999 period compared to $10.6 million in the comparable 1998 period. This
decrease is due to a decrease in assets under construction financed using
general corporate funds in the 1999 period compared to the 1998 period. Interest
income for the 1999 period was $3.3 million as compared to $4.9 million for the
1998 period.

         Lease Income. The Company recorded $17.4 million of lease income on
residences owned or leased by the Company and leased or subleased to
unconsolidated joint ventures in 1999. Lease payment obligations of the
unconsolidated joint venture entities are generally equivalent to the debt
service payable by the Company on the leased residences, and thereby offset
Company costs associated with obtaining and maintaining financing for such
residences.  The Company had no such arrangements in 1998.

         Minority Interest in Losses of Consolidated Subsidiaries. Minority
interest in losses of consolidated subsidiaries for the nine months ended
September 30, 1999 was $3.8 million, representing a decrease of $11.9 million
from $15.7 million for the comparable period in 1998. The decrease was primarily
attributable to the decrease in the number of residences in various stages of
lease-up that are owned by the Company in consolidated joint venture
arrangements during the 1999 period. During the first nine months of 1999, the
Company had an average of 17 residences held in consolidated joint venture
relationships compared to an average of 52 residences in consolidated joint
venture relationships during the first nine months of 1998.

         Income Taxes. For the nine months ended September 30, 1999, the Company
recorded a current income tax provision of $4.5 million and recognized a $4.8
million deferred tax liability resulting in a current income tax expense of $9.3
million before the effect of a cumulative change in accounting. During the nine
months ended September 30, 1998, the Company recorded a current income tax
provision of $4.3 million which was offset by the recognition of $4.9 million of
deferred tax assets resulting in a current income tax benefit of $549,000.


LIQUIDITY AND CAPITAL RESOURCES

         Historically, the Company has financed its operations and growth
through a combination of various forms of real estate financing (mortgage,
synthetic lease and sale/leaseback financing), capital contributions from joint
venture partners, the sale of its securities (common stock and convertible
debentures) and, to a lesser extent, cash from operations.  At September 30,
1999, the Company had $724.7 million of outstanding debt principally consisting
of $228.6 of convertible debentures having a weighted average interest rate of
5.86%, $252.1 million of fixed rate debt having a weighted average interest rate
of 7.56%, capitalized lease obligations of $53.2 million having a weighted
average interest rate of 9.16% and $190.8 million of variable rate debt having
a weighted average interest rate of 7.89%.

         At September 30, 1999, the Company had approximately $33.0 million in
unrestricted cash and cash equivalents and $23.7 million working capital
(compared to working capital of $40.4 million at September 30,1998).  For the
nine months ended September 30, 1999 cash flow from operations was $32.2 million
versus an operating cash flow deficit of $5.3 million for nine months ended
September 30, 1998. The significant increase in cash flow is attributable to the
greater number of consolidated residences operating at or near stabilized
occupancy levels during the 1999 period in comparison to the comparable 1998
period.  During the nine months ended September 30, 1999, the Company closed on
approximately $212.9 million of new debt financing and capital lease obligations
which included approximately $79.7 million of debt used to refinance properties
having prior debt balances of $66.1 million. Additionally, financing was
provided through $72.0 million of sale/leaseback financing and $8.5 million of
minority partner contributions.

         Net cash provided by financing activities together with cash from
operations was used during the nine month period ending September 30, 1999 to
fund $176.8 million in construction and development activity, $59.5 million in
joint venture buy-outs, $15.2 million in acquisition activity, and $9.9 million
of construction bridge financing under third party development arrangements.

         The Company has the following three series of convertible subordinated
debentures outstanding:

               -    $143.8 million aggregate principal amount of 5.25%
                    convertible subordinated debentures due December 15, 2002.
                    These convertible debentures bear interest at 5.25% per
                    annum payable semi-annually on June 15 and December 15 of
                    each year.  The conversion price is $28.75, which is
                    equivalent to a conversion ratio of 34.8 shares of common
                    stock per $1,000 in principal amount of the convertible
                    debentures.  The convertible debentures are redeemable at
                    the option of the company commencing on December 31, 2000,
                    at specified premiums.  The holders of the convertible
                    debentures may require the Company to repurchase the
                    convertible debentures; upon a change of control of the
                    Company, as defined in the convertible debenture;

               -    $50.0 million aggregate principal amount of 7.00%
                    convertible subordinated debentures due June 1, 2004.  These
                    convertible debentures bear interest at 7.00% per annum
                    payable semi-annually on June 1 and December 1 of each year.
                    The conversion price is $20.25, which is equivalent to a
                    conversion ratio of 49.4 shares of common stock per $1,000
                    in principal amount of the convertible debentures.  The
                    convertible debentures are redeemable at the option of the
                    Company commencing on June 15, 2000, at specified premiums;
                    and

               -    $35.0 million aggregate principal amount 6.75% convertible
                    subordinated debentures due June 30, 2006.  These
                    convertible debentures bear interest at 6.75% per annum
                    payable semi-annually on June 30 and December 30 of each
                    year.  The conversion price is $20.38, which is equivalent
                    to a conversion ratio of 49.3 shares of common stock per
                    $1,000 principal amount of the convertible debentures.  The
                    convertible debentures are redeemable at the option of the
                    Company commencing on July 15, 1999, at specified premiums;



         The Company's principal credit agreements and debt instruments include
various financial covenants and other restrictions, including: (i) debt service
coverage requirements, typically measured on a trailing four quarter basis,
which typically increase over the term of the applicable credit agreement; (ii)
maximum leverage ratios which limit the Company's aggregate senior indebtedness
to total capitalization; (iii) various minimum net worth or tangible net worth
requirements; (iv) in certain cases, property specific financial covenants of
the type referenced above applicable to individual properties or to the pool of
residences financed by the applicable lender; and (v) the maintenance of
operating and other reserves for the benefit of the residences serving as
collateral for the applicable lender.  In addition, under certain of its credit
and sale/leaseback facilities, the Company is required to secure lender or
lessor consent prior to engaging in certain mergers, business combinations or
change in control transactions.

         The Company's operations and growth will require significant additional
capital resources in the future in order to fund; (i) the Company's ongoing
construction and development of assisted living and Alzheimer's care
residences; (ii) the Company's purchase of minority and majority equity
interests in assisted living residences operated by the Company from the third
party joint venture partners; (iii) ongoing debt service obligations, including
maturities of its long-term debt; and (iv) certain obligations to finance the
operations of third party developments partners. Each of these principal uses
of capital resources are summarized below:

          Development Activities.  The development and construction of new,
     purpose-built assisted living and Alzheimer's care residences has
     historically been the principal use of the Company's capital resources.  In
     many markets in which the Company operates, competition has increased
     significantly in recent periods and, in selected markets, the supply of
     assisted living beds exceeds demand.  Concurrently, financing for new
     assisted living residences has become more difficult and more expensive to
     obtain. In light of this competitive environment and the tightening of the
     capital markets, the Company is actively reviewing its development
     projects not yet in construction in order to determine which to complete
     or terminate.  In conducting this analysis, the Company is considering
     market-specific and competitive factors on a site-by-site basis. The
     Company anticipates that upon completion of this review it will elect to
     discontinue a significant portion of its pending development projects and,
     accordingly, record a charge related to the write-down of markets and
     sites under development and the reduction of its development activities to
     a modest level.

         The Company will continue to construct and complete substantially all
     of the 61 residences currently in construction. The Company estimates
     that between $100.0 million and $115.0  million will be required to fund
     its ongoing construction and development activity during the next twelve
     months, depending upon the scope of its scale back of development and new
     construction activities.

         Purchase of Joint Venture Interests.  The Company is obligated under
     many of its joint venture arrangements to purchase the equity interests of
     its joint venture partners at fair market value upon the election of such
     partners. During the next twelve months, the Company will be subject to
     such contingent purchase obligations with respect to equity interests held
     by joint venture partners, exercisable at their election, related to
     certain of the Company's residences.

          At such times, or earlier, as such contingent purchase obligations are
     exercisable, the Company may also elect to exercise its rights to
     purchase such interests.  Based on a number of assumptions, including
     assumptions as to the number of residences to be operated with joint
     venture partners, the timing of such development, the time at which such
     options may be exercised and the fair market value of such residences at
     the date such options are exercised, the Company estimates that it may
     require approximately $55 million to $70 million to satisfy these purchase
     obligations during the twelve month period ending September 30, 2000.

          Debt Service.  In addition to ongoing debt service and lease payment
     obligations, including interest payments due on its convertible debentures,
     the Company will be required to fund or refinance approximately $58.8
     million of long-term indebtedness that will mature during the twelve
     months ending September 30, 2000. In addition, in the quarter ended
     September 30, 1999, the Company arranged a series of operating leases
     which were used to finance $135.9 million of the acquisition of residences
     from Manor Care, Inc.

          Advances to Development Partners. The Company has committed in certain
     circumstances to provide up to $113.9 million in financing to development
     partners under third party arrangements. The Company has advanced $17.3
     million pursuant to these arrangements as of September 30, 1999. The
     Company intends to finance these projects under existing bank credit
     facilities.

     The Company expects to fund a portion of its capital and liquidity
requirements from cash on hand, cash generated from operations, financing under
existing debt and lease commitments and equity from its joint venture
development partners.  The Company has executed non-binding letters of intent
with various healthcare REITs and other lessors with approximately $69.9
million of remaining capacity at September 30, 1999 and had available
approximately $419.8 million of remaining financing capacity from conventional
mortgage lenders as of September 30, 1999, which conventional mortgage financing
is accessible by the Company upon satisfying the respective lenders' property
underwriting requirements. Included in this $419.8 million of mortgage financing
commitments is $151.8 million of financing available under a construction loan
facility established by the Company and Manor Care, Inc. to finance projects
developed through their development joint venture relationship.  The Company
does not expect to utilize all of this financing to fund development of Company
projects.  The Company's ability to utilize non-binding financing commitments
from REITs and other lenders has become substantially limited due in part to the
volatility in the capital markets and factors affecting the assisted living
industry generally. In particular, many healthcare REITs are currently not
extending new financing.  In addition, the property level underwriting
requirements of certain of the Company's lenders are being more strictly
applied.  Accordingly, the Company's ability to secure financing on acceptable
terms has become increasingly difficult.

     The Company is currently exploring alternatives to obtain additional
sources of capital, to reduce or defer certain of its capital obligations and to
deleverage (i.e., reduce debt and other financial commitments in relation to
equity) its balance sheet.  Among the alternatives the Company is considering
are the sale of equity or convertible securities, the sale of assets in a
"sale/manage-back" transaction, altering or reducing its utilization of joint
venture development arrangements, and discontinuing or deferring development
projects. Although beneficial from a liquidity or cash flow perspective, certain
of these alternatives, if implemented, could have a material and adverse impact
upon the Company's future earnings and could require the Company to seek
modifications from its lenders with respect to certain of its financing
covenants.  There can be no assurance that the Company will be successful in
these efforts or that it will be able to access additional debt and equity
financing required to fund its operations and growth on acceptable terms in the
future.

IMPACT OF INFLATION

To date, inflation has not had a significant impact on the Company. Inflation
could, however, affect the Company's results of operations due to the Company's
dependence on its senior resident population who generally rely on liquid assets
and relatively fixed incomes to pay for the Company's services. As a result, the
Company may not be able to increase residence service fees to account fully for
increased operating expenses. In structuring its fees, the Company attempts to
anticipate inflation levels, but there can be no

                                       10
<PAGE>   13

assurance that the Company will be able to anticipate fully or otherwise respond
to any future inflationary pressures. In addition, given the amount of
construction and development activity which the Company anticipates,
inflationary pressures could affect the Company's cost of new product deployment
and financing. There can be no assurances that financing will be available on
terms acceptable to the Company.


YEAR 2000 ISSUE

As a result of certain computer programs being written using two digits rather
than four to define the applicable year, computer systems that have date
sensitive software may recognize a date using "00" as the year 1900 rather than
the year 2000 (the so called "Year 2000 Issue"). This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in normal business activities.

The Company's year 2000 readiness plan consists of:

     -   Identify and assess year 2000 issues in the Company's information and
         non-information technology systems including inquiring of third parties
         with whom it does significant business, such as vendors and suppliers,
         as to the state of their year 2000 readiness; and
     -   Repair or replace non-compliant information and non-information
         technology.

The Company has identified year 2000 risks in the following areas:

     -   THE COMPANY'S INFORMATION TECHNOLOGY SYSTEMS MIGHT NOT BE YEAR 2000
         COMPLIANT. The Company has assessed its readiness in regard to year
         2000 issues, and believe that all material hardware and software
         utilized in its operations and, specifically, in its accounting
         systems, is year 2000 compliant. This assessment included obtaining
         year 2000 certifications from all software vendors, installation of
         software patches issued by these vendors and specific year 2000 testing
         of all material software. Despite the Company's efforts to identify and
         resolve year 2000 issues, it cannot guarantee that all of its systems
         will be year 2000 compliant.

     -   THE COMPANY'S NON-INFORMATION TECHNOLOGY SYSTEMS MIGHT NOT BE YEAR 2000
         COMPLIANT. Its non-information technology systems are its building
         management and life/safety systems, which include its emergency call
         systems, electrical locking systems, fire alarm systems, fire alarm
         monitoring systems, and in limited cases, elevator systems. The Company
         has assessed its readiness of these systems in regard to year 2000
         issues by deploying approximately 12 regional maintenance personnel
         who contacted, as part of their normal course of business, all
         manufacturers and vendors of material non-information technology
         systems requesting written certification that each of their systems is
         year 2000 compliant. Any systems identified as not in compliance will
         be upgraded or replaced.

     -   THE COMPANY MAY HAVE YEAR 2000 ISSUES WITH SIGNIFICANT THIRD
         PARTIES. It has obtained year 2000 compliance letters from its major
         financial institution and tested compliance for key third party systems
         like check processing and ACH/direct deposit transmissions. However,
         some third parties, including certain utilities and the federal
         government, continue to be in the process of evaluating and updating
         their internal systems and cannot yet assure the Company that their
         systems are year 2000 compliant. The Company plans to monitor the
         progress of its major vendors in achieving year 2000 compliance and,
         where possible, develop alternative means to obtain necessary goods and
         services.

The Company does not anticipate any major interruption in its business as a
result of year 2000 issues. Accordingly, The Company does not expect that the
Year 2000 Issue will have a material adverse effect upon its operations or that
it will incur any material expense associated with year 2000 compliance.
However, despite the Company's efforts to identify and resolve year 2000
compliance problems, it cannot guarantee that all of its systems or that

                                       11
<PAGE>   14

third parties on which the Company relies will be year 2000 compliant. As a
result the Company's operations could be interrupted or adversely effected. In
the worst case scenario, if the Company's non-information technology systems
suffered year 2000 issues, it would implement it's standard emergency operation
plan. This plan primarily includes incurring additional staffing and if
necessary relocation of it's residents to alternate locations. If the Company
needs to sustain this additional staffing or were unable to occupy it's existing
buildings for an extended period of time, it could have a material adverse
effect on the Company's business and operations.

The Company has not established a contingency plan to address potential year
2000 noncompliance with respect to it's information systems or those of it's
major vendors. The Company is currently considering the extent to which such a
plan is necessary. Because the Company depends on organizations who maintain
systems outside of our control, such as telecommunications, power supplies and
the federal government, which may not have adequately addressed year 2000
issues, it cannot guarantee that it will not face unexpected problems associated
with year 2000 issues effecting it's operations, business and financial
condition.

FORWARD-LOOKING STATEMENTS

         The statements in this quarterly report relating to matters that are
not historical facts are forward-looking statements based on management's belief
and assumptions using currently available information.  Although the Company
believes that the expectations reflected in such forward-looking statements are
reasonable, it cannot give any assurances that these expectations will prove to
be correct.  Such statements involve a number of risks and uncertainties,
including, but not limited to, substantial debt and operating lease payment
obligations, operating losses associated with new residences, the ability to
manage rapid growth and business diversification, the need for additional
financing, development and construction risks, risks associated with
acquisitions, competition, governmental regulation and other risks and
uncertainties detailed in the reports filed by the Company with the Securities
and Exchange Commission.  Should one or more of these risks materialize (or the
consequences of such a development worsen) or should the underlying assumptions
prove incorrect, actual results could differ materially from those forecasted or
expected.  The Company assumes no duty to publicly update such statements.

ITEM 3.           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Market risk represents the risk of changes in value of a financial
instrument, derivative or non-derivative, caused by fluctuations in interest
rates, foreign exchange rates and equity prices. Changes in these factors may
cause fluctuations in the Company's earnings and cash flows.

         The Company performed a sensitivity analysis which presents the
hypothetical change in fair value of those financial instruments held by the
Company at September 30, 1999 which are sensitive to changes in interest rates.
Market risk is estimated as the potential change in fair value resulting from an
immediate hypothetical one percentage point parallel shift in the yield curve.
The fair value of the debt included in the analysis is $199.5 million. Although
not expected, a one percentage point change in the interest rates would have
caused the Company's annual interest expense to change by approximately $1.5
million. Accordingly, a significant increase in LIBOR based interest rates could
have a material adverse effect on the Company's earnings.

         Although a majority of the debt and lease payment obligations of the
Company as of or during the three months ended, September 30, 1999 are not
subject to floating interest rates, indebtedness that the Company may incur in
the future may bear interest at a floating rate. Debt and annual operating lease
payment obligations will continue to increase as the Company pursues its growth
strategy.

         The Company does not presently use financial derivative instruments to
manage its interest costs. The Company does not use foreign currency exchange
rate forward contracts or commodity contracts and does not have foreign currency
exposure as of September 30, 1999.

that the lien of this Instrument shall not apply to, and there shall be excluded
from the ambit of this paragraph, any of the foregoing permits, licenses,
franchises, privileges, grants, consents, building variances, certificates of
occupancy or operation, and other authorizations or approvals, which, by their
express terms or by reason of applicable law would become void or voidable if
mortgaged or pledged by the Borrower hereunder.

the fact that the amount owing thereon may not then be due and payable or that

         It is also agreed that if any of the property herein mortgaged is of a
nature so that a security interest therein can be perfected under the Uniform
Commercial Code, this Instrument shall constitute a security agreement and the
Borrower agrees to execute, deliver and file or refile any financing statement,
continuation statement, or other instruments the Collateral Agent may require
from time to time to perfect or renew such security interest under the Uniform
Commercial Code. This Instrument shall be effective as a financing statement and
is to be filed for record in the Office of the County Recorder or County Clerk
where the Premises are situated. The mailing address of the Borrower is set
forth at the beginning of this Instrument and the address of the Collateral
Agent from which information concerning the security interest may be obtained is
the address of the Collateral Agent set forth at the beginning of this
Instrument.

         The Borrower represents to and covenants with the Collateral Agent, its
successors and assigns, that at and until the ensealing of these presents: (i)
the Borrower is well seized of and has a good and indefeasible estate in fee
simple in the Premises (other than any portion of the Premises which is the
subject of a Ground Lease in favor of the Borrower); (ii) if the Borrower's
interest in any portion of the Premises is held by it under a Ground Lease, the
Borrower has a valid and subsisting leasehold estate in each of the properties
covered by such Ground Lease; (iii) the Borrower has good title to the Personal
Property Collateral; (iv) the Borrower and has good right to mortgage, warrant,
bargain, sell and convey, and create a security interest in, the Property

the appurtenances thereunto belonging to the Collateral Agent, its successors
and assigns, forever against all lawful claims, and demands whatsoever; (vi) the
Property Covered by this Instrument is free and clear of all liens and
encumbrances except only those listed in Exhibit 2, attached hereto and made a
part hereof by reference; (vii) the Property Covered by this Instrument and the
intended use thereof by the Borrower comply to the best of the Borrower's
knowledge with all applicable restrictive covenants, zoning ordinances and
building codes and flood disaster laws, and, to the extent that noncompliance
therewith would materially adversely affect the ability of the Borrower to
conduct its business on the Property Covered by this Instrument, or the value or
marketability of the Property Covered by this Instrument, all applicable
occupational, health and environmental and other applicable laws, rules and
regulations of any other governmental authority whatsoever; and (viii) the
Borrower will execute, acknowledge and deliver all necessary assurances to the
Collateral Agent of the title to the Property Covered by this Instrument as
provided above.

         If the Borrower hereafter acquires any real property, or any interest
in real property, in addition to the Real Property, which is adjacent to, or
contiguous with, or otherwise intended or required to be subjected to the lien
of this Instrument, the Borrower will subject the same to the lien of this
Instrument by instrument supplemental hereto, satisfactory in form and substance
to the Collateral Agent and Trustee.

         The conditions of this Instrument are such that the Borrower has
executed and delivered this Instrument for the purpose of securing the
performance of its covenants and agreements contained herein and in any
agreement or instrument made by it with respect to any Indebtedness secured
hereby and to secure the payment when due (whether at the stated maturity, by
acceleration or otherwise) of the following indebtedness, liabilities and
obligations (including obligations which, but for the automatic stay under
section 362(a) of the Bankruptcy Code, would become due), now existing or
hereafter arising (collectively, the "INDEBTEDNESS", the "INDEBTEDNESS SECURED
BY THIS INSTRUMENT" or the "INDEBTEDNESS SECURED HEREBY"), ratably, although not
necessarily in the order of priority set forth below:

         (a)      the aggregate principal amount of $6,080,000, representing the
                  Loans made or to be made to the Borrower under the Credit
                  Agreement with respect to the Project, with interest thereon,
                  as evidenced by the Notes, maturing on or prior to the 18th
                  monthly anniversary of the date this Instrument is recorded in
                  the real property records of the jurisdiction in which the
                  Premises are located (unless such date is extended as provided
                  in the Credit Agreement); and principal and interest on the
                  Notes in respect of such Loans shall be payable as set forth
                  therein and in the Credit Agreement;

         (b)      all sums expended or advanced by or on behalf of the
                  Collateral Agent pursuant to any term or provision of this
                  Instrument or any other agreement or instrument relating to or
                  securing any of the foregoing for the purpose of protecting or
                  preserving the Property Covered by this Instrument or the
                  priority of the Lien of this Instrument, including, all
                  advances or disbursements of the Collateral Agent for the
                  payment of taxes, levies, assessments, insurance, insurance
                  premiums or costs incurred in the protection of the Property
                  Covered by this Instrument;

                                       5
<PAGE>   7


         (c)      all other liabilities, obligations and indebtedness of the
                  Borrower incurred under or arising out of or in connection
                  with the Credit Agreement and the other Credit Documents to
                  which it is a party, and the due performance and compliance by
                  the Borrower with all of the terms, conditions and agreements
                  contained in the Credit Agreement and such other Credit
                  Documents;

         (d)      all other liabilities, obligations and indebtedness of the
                  Borrower and/or any other Credit Party under any Designated
                  Hedge Agreement, whether relating to the Loans for the Project
                  or to any other Project financed or to be financed pursuant to
                  the Credit Agreement; and

         (e)      all other liabilities, obligations and indebtedness of the
                  Company and the other Borrowers incurred under or arising out
                  of or in connection with the Credit Agreement and the other
                  Credit Documents to which the Company or any other Borrower is
                  a party, and the due performance and compliance by the Company
                  and the other Borrowers with all of the terms, conditions and
                  agreements contained in the Credit Agreement and such other
                  Credit Documents;

but only to the extent that the total unpaid Indebtedness secured by this
Instrument, exclusive of liabilities and obligations referred to in the
preceding clause (c), in the aggregate, exclusive of the interest thereon, does
not exceed the maximum amount specified in this Instrument, which is $6,080,000,
and as security for the payment of the Indebtedness secured hereby, the Borrower
has granted to the Trustee hereunder a lien against the Property Covered by this
Instrument. In accordance with the provisions of the Notes, the whole of the
principal sum of the Loans made to finance the Project which are then unpaid may
be declared and become due and payable upon the occurrence of an Event of
Default hereunder or under the Credit Agreement. This Instrument is given for
the purpose of creating a lien on the Property Covered by this Instrument and
expressly is to secure the Indebtedness secured hereby, ratably, including but
not limited to future advances, whether such advances are obligatory or to be
made at the option of the Lenders or otherwise, to the same extent as if such
future advances were made on the date of the execution of this Instrument. The
total amount of the Indebtedness secured hereby may decrease or increase from
time to time and the Lenders may hereafter, as described in this Instrument, at
any time after this Instrument is delivered to the county recorder or county
clerk for record, make additional loans or advances to the Borrower or otherwise
make credit facilities available for the account of the Borrower or any the
other Borrowers; PROVIDED, HOWEVER, that the total unpaid balance secured at any
one time shall not exceed $6,080,000, plus interest thereon and any
disbursements made for the payment of taxes, levies or insurance on the Property
Covered by this Instrument with interest on such disbursements. Any such further
loans or advances or credit facilities, with interest, shall be secured by this
Instrument.

         PROVIDED, NEVERTHELESS, that if the Indebtedness secured hereby shall
be paid in full when due, and if all of the provisions of the Credit Agreement
and the other Credit Documents shall be timely performed and observed, then the
lien of this Instrument and the interest of the Trustee in the Property Covered
by this Instrument shall be released at the cost of the Borrower, but shall,
except as otherwise provided herein, remain in full force and effect.

         The Borrower, intending to bind its successors and assigns, hereby
covenants and agrees with the Collateral Agent and Trustee, its
successors-in-trust and assigns, for its benefit and for the benefit of the
holders of the Indebtedness secured hereby, as follows:

         1        PAYMENT OF LOANS, PERFORMANCE OF OBLIGATIONS, ETC. (a) The
Borrower shall pay the principal of and interest on its Loans incurred to
finance the Project in accordance with the Credit Agreement.

         (b)      The Borrower hereby irrevocably authorizes the Company to take
any and all actions on behalf of the Borrower contemplated to be taken as
provided in the Credit Agreement.

         (c)      The Borrower hereby (i) undertakes and agrees to perform all
of the obligations of a Borrower under the Credit Agreement, and (ii) agrees to
be bound to all of the limitations, conditions, restrictions and other
provisions of the Credit Agreement applicable to a Borrower.



                                       6












<PAGE>   8


         (d)      The Borrower will keep and perform or cause to be kept and
performed all covenants, agreements, conditions and stipulations contained in
the other Credit Documents binding on or otherwise applicable to the Borrower
under any of the other Credit Documents.

         (e)      The Borrower hereby waives promptness, diligence, notice of
acceptance and any other notice with respect to any of the Indebtedness secured
hereby and this Instrument and any requirement that the Collateral Agent or
other holder of any of the Indebtedness secured hereby protect, secure, perfect
or insure any security interest or lien or any property subject thereto or
exhaust any right or take any action against any other person, or any
collateral, or pursue any other remedy in the power of the Collateral Agent or
other holder of any of the Indebtedness secured hereby.

         2        GROUND LEASES. If the Borrower holds any interest in the
Premises under a Ground Lease, the Borrower shall maintain such Ground Lease in
full force and effect and shall duly and punctually perform all of its
obligations thereunder.

         3        ESCROW OF TAXES AND INSURANCE PREMIUMS. In order more fully to
protect the security of this Instrument, the Borrower shall, subject to any
provisions of any Ground Lease requiring payment of such amounts thereunder, pay
to the Collateral Agent, in addition to any amounts otherwise payable by the
Borrower hereunder in respect of the Indebtedness hereby secured, and
concurrently therewith but not less frequently than monthly (on the first day of
each month) until the Indebtedness is fully paid, the following sums:

                  (a)   A sum equal to one-twelfth (1/12) of the estimated
         annual cost of all taxes, assessments and levies levied on the Real
         Property and one-twelfth (1/12) of the annual insurance premiums
         required to keep the buildings, fixtures and equipment of the Real
         Property insured as required by section 10 hereof against loss or
         damage for the benefit of, with loss payable to, and in the manner and
         amount approved by, the Collateral Agent, which monthly payments shall
         be credited to an escrow account, held by the Collateral Agent, without
         interest accruing thereon, from which the Collateral Agent shall pay
         each of the such particular items. The amount of the estimated monthly
         payment under this section may be adjusted from time to time so that
         the amount deposited by the Borrower shall approximate the total sum
         required annually for such taxes, assessments, levies and insurance
         premiums. This adjustment shall be made on the demand of the Collateral
         Agent and any deficiencies shall be paid by the Borrower upon the
         Collateral Agent's demand. If funds in the escrow account are
         insufficient to pay any taxes, assessments, levies or insurance
         premiums and the Borrower has failed, refused or neglected to pay the
         same as they become due, the Collateral Agent may, but shall have no
         obligation to, pay the same plus any interest or penalties due thereon.
         Any such amount so paid by the Collateral Agent shall be added to the
         Indebtedness forthwith with interest at the rate specified in section
         2.9(c) of the Credit Agreement (hereinafter referred to as the "DEFAULT
         RATE"). No later than 10 days prior to the date when any installment of
         taxes and assessments is due, without penalty, interest, or
         delinquency, the Borrower shall present to the Collateral Agent the
         bill for any such installment of taxes and assessments and the
         Collateral Agent shall immediately draw a check on the escrow account,
         payable to the appropriate governmental authority, for the amount of
         such installment (to the extent such funds exist in the escrow
         account), and shall deliver such check to the Borrower. Upon receipt of
         such check by the Borrower, the Borrower shall pay and discharge the
         same, the Borrower shall submit to the Collateral Agent evidence of the
         due and punctual payment of such taxes, assessments, reassessments and
         other governmental charges as the Collateral Agent may require. Any
         deficiency in the fixed amount of any such aggregate monthly payment
         not paid as required shall constitute an Event of Default under this
         Instrument. In the event of a sale of the Property Covered by this
         Instrument, but without it being considered a waiver of any rights
         contained in section 6 hereof, any such funds then on deposit with the
         Collateral Agent, automatically and without necessity of further notice
         or written assignment, shall be transferred to and held thereafter for
         the account of the new owner to be applied in accordance with the
         foregoing; PROVIDED, HOWEVER, that in the event there are any defaults
         hereunder at the time of a sale of the Property Covered by this
         Instrument, such funds may be used by the Collateral Agent to satisfy
         such defaults. Any excess funds accumulated remaining after payment of
         the items therein mentioned shall be credited to subsequent monthly
         payments of the same nature required hereunder, but if any such item
         shall exceed the estimate therefor, the Borrower shall upon demand
         forthwith make good the deficiency. Failure to do so before the due
         date of such item shall be a default hereunder. If the Property Covered
         by this Instrument are sold under foreclosure or are otherwise acquired
         by the Collateral Agent after default, any remaining balance of the
         above accumulations shall, at the option of the Collateral




                                       7









<PAGE>   9

         Agent, be credited to the principal amount of the Indebtedness secured
         hereby as of the date such estates are acquired. The Borrower will also
         pay all taxes and assessments or charges which may be levied on the
         Indebtedness secured hereby or the interest therein excepting the
         federal income tax imposed under the laws of the United States and
         excepting state franchise and state income taxes. Any assessment which
         is payable in installments at the application of the Borrower shall,
         nevertheless, for the purposes of this section, be deemed due and
         payable by the Borrower in its entirety on the day the first
         installment becomes due or payable or a lien, unless the written
         approval of the Collateral Agent is obtained for any such installment
         payments of assessments.

                  (b)   Notwithstanding the provisions of section 3(a) above,
         (i) the Borrower shall have the right to contest in good faith any of
         such taxes and assessments upon posting with the Collateral Agent
         sufficient security, reasonably satisfactory to the Collateral Agent,
         for the payment thereof, with interest, costs and penalties, under
         written agreement conditioning payment of such contested taxes and
         assessments upon the resolution of such contest, or prior thereto if
         the continuance of such contest shall put the Property Covered by this
         Instrument or any part thereof in jeopardy of tax sale or forfeiture;
         and (ii) so long as there exists no Event of Default under this
         Instrument, the Borrower may make such payments of insurance premiums,
         taxes, assessments, levies, and other charges directly and without
         making the payments to the escrow account contemplated by section 3(a)
         above, but in the event of the occurrence and continuance of an Event
         of Default under this Instrument, the provisions set forth above in
         section 3(a) providing for payments to such escrow account shall be
         fully applicable and in full force and effect.

         4        REVENUE STAMPS; TAXES ON INDEBTEDNESS. (a) If at any time the
United States of America shall require internal revenue stamps to be affixed to
any of the Indebtedness secured hereby, the Borrower will pay for the same with
any interest or penalties imposed in connection herewith.

         (b)      If at any time the United States or the State or Commonwealth
in which the Real Property is located or any of their subdivisions having
jurisdiction shall levy, assess or charge any tax, assessment or imposition upon
this Instrument or the credit or Indebtedness secured hereby or the interest of
the Collateral Agent in the Real Property or upon the Collateral Agent or any
Lender by reason of or as holder of any of the foregoing, then the Indebtedness
secured hereby and the accrued interest thereon shall be and become due and
payable at the election of the Collateral Agent; PROVIDED, HOWEVER, that such
election and the right to elect shall be unavailing if the Borrower lawfully may
pay for such stamps or such tax, including interest and penalties thereon, to or
for the benefit of the Collateral Agent and the other holders of the
Indebtedness secured hereby, and the Borrower elects to pay and does, in fact,
pay when payable, for all such stamps or such tax, as the case may be, including
interest and penalties thereon, prior to any such election by the Collateral
Agent. The Borrower further agrees to deliver to the Collateral Agent, at any
time, upon demand, evidence of citizenship and such other evidence as may be
required by any government agency having jurisdiction in order to determine
whether the Indebtedness secured hereby is subject to or exempt from any such
tax or any other governmental filing or reporting requirement.

         5        LIENS. (a) The Borrower shall not create or suffer to exist
any lien, security interest, charge, restriction or other encumbrance affecting
all or any portion of the Property Covered by this Instrument, and shall keep
the Property Covered by this Instrument free and clear from any of the
foregoing, EXCEPT FOR (1) the lien of this Instrument, (2) taxes and assessments
which may be a lien but are not yet due and payable, (3) easements, licenses and
similar rights granted in the ordinary course of business to suppliers of gas,
oil, electricity, cable or satellite television, telephone, wireless
communication and similar services, (4) purchase money liens on equipment and
vehicles, and rights of lessors under Capital Leases of equipment or vehicles,
in each case which are permitted under section 16(c) hereof, (5) such other
matters of record as may be described in Exhibit 2 or as to which the Collateral
Agent has otherwise specifically consented in writing, (6) mechanics' liens and
other statutory liens which (w) secure amounts not more than 30 days overdue, or
(x) are being contested in accordance with section 5(b), or (y) are "bonded
over" in a manner reasonably acceptable to the Collateral Agent, or (z)
otherwise do not appear as exceptions on the Title Policy (and endorsements
thereto) issued in favor of the Collateral Agent with respect hereto, and (7)
Tenant Leases entered into in accordance with section 6 hereof.

         (b)      If any lien, security interest, charge, restriction or other
encumbrance affecting all or any portion of the Property Covered by this
Instrument, not otherwise permitted by section 5(a), shall be filed in the real
property

records in which this instrument is recorded, the Borrower will have the same
discharged of record either by payment, the bonding thereof or other lawful
means. Without limitation of the foregoing, the Borrower will keep and maintain
the Property Covered by this Instrument free from mechanics' liens and other
statutory liens securing claims of all persons supplying labor, materials or
services which will enter into or otherwise contribute to the construction of
any and all buildings now being erected or which hereafter may be erected on the
Real Property, notwithstanding by whom such labor or materials may have been
contracted; PROVIDED, HOWEVER, that the Borrower shall have the right to contest
in good faith any such mechanics' lien or statutory lien (i) so long as the
continuance of such contest or litigation does not result in an order for the
foreclosure of such lien, the forced sale of any of the Property Covered by this
Instrument, or the forfeiture of the lien of this Instrument, and (ii) in the
case of any such mechanics' lien or statutory lien involving a claim in excess
of $100,000, there has been posted with the Collateral Agent sufficient security
(in the form of a bond issued by a surety company or otherwise), satisfactory to
the Collateral Agent, for the payment thereof, with interest, costs and
penalties, under written agreement conditioning payment of such contested
mechanics' lien or statutory lien upon the resolution of such contest, or prior
thereto.

         6        TRANSFERS AND MERGERS; LEASES AND MANAGEMENT CONTRACTS, ETC.
The Borrower shall not (i) sell, assign, transfer or otherwise dispose of the
Property Covered by this Instrument or any part thereof or interest therein, or
(ii) merge or consolidate with any other person, or (iii) amend, modify,
terminate or surrender any Ground Lease, or (iv) enter into any management
contract or similar agreement under which any person other than the Borrower
shall have the right to manage the operation of the Project, or (v) lease all or
any portion of the Property Covered by this Instrument to any other person,
pursuant to a Tenant Lease, or otherwise, or permit any of its lessees or
sublessees to do so, or (vi) enter into any contract or agreement to do any of
the foregoing, expressly including, without limitation, any land contract,
lease/purchase, lease/option or option agreement, without, in each such case,
first obtaining the written consent of the Collateral Agent; EXCEPT, HOWEVER,
that the Borrower shall have the right, without such consent, to

                  (A)   sell, assign or transfer all of its right title and
         interest in the Property Covered by this Instrument to the Company or
         to another Affiliate of the Company, or merge or consolidate with the
         Company or another Affiliate of the Company, if (1) no Event of Default
         under this Instrument shall have occurred and be continuing, or would
         result therefrom, (2) the obligations of the Permanent Lender or the
         Supplemental Permanent Lender under the Project Take-Out Agreement
         related to the Borrower's Project, or under any commitment issued by it
         to the Borrower which is referred to therein, would not be impaired,
         subject to termination, or otherwise adversely affected in any manner
         which might jeopardize the ability of the Borrower to refinance its

         PROVIDED that at the time any such Affiliate Lease is entered into, no
         Event of Default under this Instrument shall have occurred and be
         continuing, or would result therefrom;

                  (E)   sublease units of the Project to individual residents in
         the ordinary course of business pursuant to Tenant Leases, or permit
         the Company or any Affiliate if it is a party to a Management Contract,

         simultaneously with or prior to such removal, such equipment shall, if
         required in order to continue operations on the Property Covered by
         this Instrument at the same level of activity as prior to such removal,
         be replaced with equipment of like kind and quality, free from any
         security interest, lien or encumbrance not permitted under the
         provisions of the Credit Agreement or the other Credit Documents, and

grant any rights in the Property Covered by this Instrument or any part thereof
to the tenant named therein. No sale or transfer of the Borrower's interest in
the Property Covered by this Instrument permitted by clause (A) above shall
operate as a release of the Borrower from its obligations hereunder or in
respect of the Indebtedness secured hereby without the written consent of the
Collateral Agent (acting on instructions from the Required Lenders, or all of
the Lenders if required under section 13.13 of the Credit Agreement), and in the
event of any such sale or transfer, the Collateral Agent may, without notice to
the Borrower, deal with such assignee with reference to this Instrument and the
obligations hereunder in the same manner as with the Borrower, without in any
way releasing, discharging or otherwise affecting the Borrower's liability
hereunder, or the Indebtedness secured hereby.

         (b)      After completion of construction of the Improvements as
contemplated by the Credit Agreement and the other Credit Documents, no
buildings or substantial improvements on the Property Covered by this Instrument
shall be altered or demolished or removed by the Borrower without the prior
written consent of the Collateral Agent (which consent shall be given as
provided in section 13.13 of the Credit Agreement upon instructions or consent
of the Required Lenders), PROVIDED that the proposed alterations shall not
materially and adversely affect the value of the Property Covered by this
Instrument or the utility of the Property Covered by this Instrument for the
purposes to which the same are designed or presently devoted); PROVIDED,
FURTHER, HOWEVER, the Borrower may make alterations to the Property Covered by
this Instrument (including structural or material alterations to the buildings
or improvements thereon) without such consent if (i) such alterations do not
reduce the value or marketability of the Property Covered by this Instrument or
the uses or utility of the Property Covered by this Instrument; or (ii) if such
alterations are not required by applicable law, if the cost of all such
alterations (whenever made) taken in the aggregate do not cost more than
$250,000. In the event the Collateral Agent's consent is required, the Borrower
in requesting such consent shall submit to the Collateral Agent plans and
specifications for such alterations and a cost estimate satisfactory to the
Collateral Agent, which plans and specifications and cost estimate shall be
prepared by a registered architect selected by the Borrower and reasonably
acceptable to the Collateral Agent.

         (c)      If the Improvements suffer any damage or loss or are destroyed
by fire, rain, storm, flood, earthquake, or any other casualty, whether or not
covered by insurance, the Borrower will (i) if the same constitutes an Event of
Loss, prepay its Loans related to the Project as provided in the Credit
Agreement, or (ii) otherwise repair, replace or restore the Improvements in
accordance with the requirements of this Instrument applicable to the
construction or alteration of the Improvements.

         8        COMPLIANCE WITH LAWS AND INSURANCE REQUIREMENTS, ETC. (a) The
Borrower covenants that the Real Property and Improvements will at all times be
constructed, maintained and operated in compliance with all applicable
requirements of

                  (i)   all laws, rules, regulations, orders, authorizations,
         permits and licenses of all governmental authorities, federal, state
         and local, having jurisdiction over the Borrower, the Real Property or
         the Improvements, including, without limitation, (x) all Environmental
         Laws, and (y) the Americans with Disabilities Act of 1990, the Fair
         Housing Amendments Act of 1988, all state and local laws and ordinances
         related to handicapped access and all rules, regulations, and orders
         issued pursuant thereto including, without limitation, the Americans
         with Disabilities Act Accessibility Guidelines for Buildings and
         Facilities (collectively as referred to in this clause (y), "ACCESS
         LAWS"); and

                  (ii)  all restrictive covenants affecting any portion or all
         of the Real Property;

other than those requirements (A) being contested in good faith by appropriate
proceedings, as to which adequate reserves are established to the extent
required under GAAP, and (B) the noncompliance with which would not have, and
which would not be reasonably expected to have, a Material Adverse Effect or a
material adverse effect on the ability of the Borrower to perform its
obligations under any Credit Document.

         (b)      Notwithstanding any provisions set forth herein or in any
other document regarding the Collateral Agent's approval of alterations of the
Real Property, the Borrower shall not alter the Real Property in any manner
which would increase in any material respect the responsibilities of the
Borrower for compliance with the applicable Access Laws without the prior
written approval of the Collateral Agent. The foregoing shall apply to tenant
improvements constructed by the Borrower or by any of its tenants. The
Collateral Agent may condition any such approval upon receipt of a certificate
of Access Law compliance from an architect, engineer, or other person acceptable
to the Collateral Agent.

         (c)      The Borrower does hereby agree to give prompt notice to the
Collateral Agent of the receipt by the Borrower of any complaints related to
violation of any Access Laws and of the commencement of any proceedings or
investigations which relate to compliance with applicable Access Laws.

         (d)      The Borrower shall (i) observe and comply with all conditions
and requirements necessary to preserve and extend any and all rights, licenses,
permits (including but not limited to zoning variances, special exceptions and

to or contracted for by the Borrower in connection with any existing or
presently contemplated use of the Property Covered by this Instrument, and (ii)
obtain and keep in full force and effect all necessary governmental and
municipal approvals as may be necessary from time to time to comply in all
material respects with all Environmental Laws, Access Laws and other statutory
or regulatory requirements; except in any such case referred to in clause (i) or
(ii) above where the noncompliance would not have, and would not be reasonably
expected to have, a Material Adverse Effect or a material adverse effect on the
ability of the Borrower to perform its obligations under any Credit Document.

         (e)      The Borrower shall observe and comply with any and all
conditions attached to the insurance relating to the Property Covered by this
Instrument and the condition thereof.

         likelihood (in the Borrower's reasonable judgment) of resulting in a
         Material Adverse Effect upon the Borrower or any material liabilities
         for the Project: (A) any notices (whether such notices are received

         to be classified as "border zone property" under the provisions of any
         Hazardous Materials Laws, or to be otherwise subject to any
         restrictions on the ownership, occupancy, transferability or use of the

         however, that nothing contained in this paragraph shall be deemed to
         (x) create or give any rights to any person other than the indemnified
         persons described herein, it being intended that there shall be no
         third party beneficiary of such provisions beyond the persons to be
         indemnified as described herein, or (y) preclude the Borrower from
         seeking indemnification from, or otherwise proceeding against, any

         if the Borrower takes any remedial action in response to the presence
         of any Hazardous Materials or Wetlands in, on, under, around or above
         any

         portion of the Property Covered by this Instrument or enters into any
         settlement agreement, consent decree, or other compromise in respect to
         any Hazardous Material or Wetlands Claims.

                  (h)   Upon the Collateral Agent's learning of the presence on
         the Property Covered by this Instrument of any Hazardous Materials, or
         any material actual or alleged liabilities, costs or expenses related
         to environmental matters affecting the Property Covered by this
         Instrument, the Collateral Agent may request the Borrower to retain
         (and if so requested the Borrower shall retain), at the Borrower's sole
         cost and expense, a licensed geologist, industrial hygienist or an
         environmental consultant (referred to hereinafter as the "CONSULTANT"),
         selected by or otherwise acceptable to the Collateral Agent, to conduct
         a baseline investigation of the Property Covered by this Instrument for
         the presence of Hazardous Materials or Wetlands ("ENVIRONMENTAL
         STUDY"). The Environmental Study shall be performed in a manner
         reasonably calculated to discover the presence of Hazardous Materials
         contamination or Wetlands and shall be conducted in accordance with the
         general standards of persons providing such services taking into
         consideration the known current and past uses of the Property Covered
         by this Instrument and property in the vicinity of the Premises and any
         factors unique to the Premises. The Consultant shall concurrently
         deliver the results, recommendations and conclusions of its
         investigation in writing (the "REPORT") directly to the Borrower and
         the Collateral Agent. The Borrower shall cause the Consultant to permit
         the Collateral Agent and the Lenders to rely on the results,
         recommendations and conclusions contained in the Report. Such results,
         recommendations and conclusions shall be kept confidential by the
         Borrower, the Lenders and the Collateral Agent unless any such person
         legally compelled or required to disclose such results or disclosure is
         reasonably required in order to pursue rights or remedies provided
         herein or at law.

                  (i)   The Borrower's representations, warranties, and
         obligations under this section shall not be terminated, released,
         discharged, extinguished, or otherwise affected by any foreclosure of
         any indebtedness or obligation, any satisfaction of the Indebtedness
         secured hereby or the release or discharge of the Property Covered by
         this Instrument or any part thereof or any other action or thing,
         except and unless such representations, warranties, and obligations are
         expressly released in writing by the Collateral Agent, which writing
         shall refer particularly to this section. The provisions of this

policy of insurance required to be maintained hereunder a certificate as to the
new or renewal policy.

         (b)      All amounts recoverable under any policy of casualty insurance
are hereby assigned to the Collateral Agent and, in the event of a loss, the

handling thereof, to apply the net proceeds to the Indebtedness in accordance
with the provisions of the Credit Agreement if at such time an Event of Default
has occurred and is continuing or the Borrower is at the time required to prepay
its Notes. If any such net proceeds are not to be so applied, the Collateral
Agent is authorized, at its option, to apply the net proceeds in any one or more
of the following ways: (i) use the same or any part thereof to fulfill any of
the covenants contained herein as the Collateral Agent may determine; (ii) use
the same or any part thereof to replace and restore the Property Covered by this
Instrument to a condition satisfactory to the Collateral Agent; or (iii release
the same or any part thereof to the Borrower to cover the cost of repair or

in respect of such event (other than proceeds in respect of business
interruption insurance) are less than $250,000, such net proceeds shall be paid
over to or retained by the Borrower unless an Event of Default has occurred and
is continuing, and shall be applied by it to the cost of repair or restoration
of the Project, and (B) all proceeds of business interruption insurance shall be
paid over to or retained by the Borrower unless an Event of Default has occurred
and is continuing.

Borrower as attorney for the Borrower to assign any policy to itself or its
nominees in the event of the foreclosure of this Instrument. In the event of


                                       16

foreclosure of this Instrument, or other transfer of title of the Property

Instrument or any easement therein or appurtenance thereof, including severance
and consequential damage and change in grade of streets, and will deliver to the
Collateral Agent copies of any and all papers served in connection with any such
proceedings. The Borrower agrees that all awards heretofore or hereafter made by
any public or quasi-public authority to the present and all subsequent owners of
the Property Covered by this Instrument by virtue of an exercise of the right of
eminent domain by such authority, including any award for taking of title,
possession or right of access to a public way, or for any change of grade or

thereto, hereby assigned to the Collateral Agent and the Collateral Agent at its
option is hereby authorized, directed and empowered to collect and receive the
proceeds of any such awards from the authorities making the same and to give
proper receipts therefor. After deducting from such proceeds any expenses
incurred by the Collateral Agent in the collection or handling thereof, the
Collateral Agent shall apply the net proceeds to the Indebtedness in accordance
with the provisions of the Credit Agreement if at such time an Event of Default
has occurred and is continuing or the Borrower is at the time required to prepay
its Loans. If any such net proceeds are not to be so applied, the Collateral
Agent is authorized, at its option, to apply the net proceeds in any one or more
of the following ways: (A) use the same or any part thereof to fulfill any of
the covenants contained herein as the Collateral Agent may determine; (B) use
the same or any part thereof to replace and restore the Property Covered by this
Instrument to a condition satisfactory to the Collateral Agent; or (C) release
the same or any part thereof to the Borrower to cover the cost of repair or
restoration of the Improvements; PROVIDED that (1) if the aggregate net proceeds
in respect of such event (other than proceeds in respect of business
interruption insurance) are less than $250,000, such net proceeds shall be paid
over to or retained by the Borrower unless an Event of Default has occurred and
is continuing, and shall be applied by it to the cost of repair or restoration
of the Project, and (2) all proceeds of business interruption insurance shall be
paid over to or retained by the Borrower unless an Event of Default has occurred
and is continuing.

         (b)      The Borrower hereby covenants and agrees to and with the
Collateral Agent, upon the request of the Collateral Agent to make, execute and
deliver any and all assignments and other instruments sufficient for the purpose
of assigning all such awards to the Collateral Agent, free and clear and
discharged of any and all encumbrances of any kind or nature whatsoever except
as above stated. Notwithstanding any taking under the power of eminent domain,
alteration of the grade of any street, or other injury to or decrease in value
of the Property Covered by this Instrument by any public or quasi-public
authority or corporation, the Borrower shall continue to pay installments on the
Indebtedness owed by it and any reduction in the principal sum resulting from
the application by the Collateral Agent of such award or payment as hereinafter
set forth shall be deemed to take effect only on the date of such receipt.

         12.      RIGHT OF COLLATERAL AGENT TO MAKE PAYMENTS ON BEHALF OF
BORROWER, ETC. (a) In the event the Borrower shall fail to comply with any or
all of its covenants, agreements, conditions and stipulations herein set forth,
then the Collateral Agent shall after notice to the Borrower be and hereby is
authorized and empowered at its option, but without legal obligation to do so,

Collateral Agent is authorized and empowered at its option, but without legal
obligation to do so, to enter, or have its agents enter, the Property Covered by
this Instrument whenever necessary for the purpose of inspecting the Property
Covered by this Instrument and curing any default hereunder. The Borrower agrees
that the Collateral Agent shall thereupon have a claim against the Borrower for
all sums paid by the Collateral Agent for such defaults so cured, together with
a lien upon the Property Covered by this Instrument for the sum so paid plus
interest at the Default Rate.

         (b)      The Collateral Agent, in making any payment herein and hereby
authorized in the place and stead of the Borrower (i) relating to taxes,
assessments, water rates, sewer rentals and other governmental or municipal
charges, fines, impositions or liens asserted against the Property Covered by
this Instrument, may do so according to any bill, statement or estimate procured
from the appropriate public authority without inquiry into the validity thereof;
or (ii) relating to any adverse title, lien, statement of lien, encumbrance,
claim or charge, shall be the sole judge of the validity of same; or (iii)
otherwise relating to any purpose herein and hereby authorized, but not
enumerated in this section, may do so whenever, in its good faith judgment and
discretion, such payment shall seem necessary or desirable to protect


                                       17

the full security intended to be created by this Instrument. In connection with
any such payment, the Collateral Agent, at its option, may and is hereby
authorized to obtain a continuation report of title prepared by a title
insurance company, the cost and expenses of which shall be repayable by the
Borrower upon demand and shall be secured hereby.

         13.      SECURITY AGREEMENT PROVISIONS. This Instrument is hereby
deemed to be as well a security agreement within the meaning of the Maryland
Uniform Commercial Code for the purpose of creating hereby a security interest

Instrument:

         (a)      grants to the  Collateral  Agent a security  interest  in all
                  of the Borrower's right, title and interest in and to all
                  Personal Property Collateral, including, but not limited to,

                  hereafter acquired and used or obtained for use on, or in
                  connection with, the Real Property; the proceeds of the
                  Personal Property Collateral are intended to be secured
                  hereby; PROVIDED, HOWEVER, that such intent shall never
                  constitute an expressed or implied consent on the part of the
                  Collateral Agent to the sale of any or all Personal Property
                  Collateral except as provided in section 6;

         (b)      agrees that the security interest hereby granted by this

         (c)      agrees not to sell, convey, mortgage or grant a security
                  interest in, or otherwise dispose of or encumber, any of the

                  title or interest therein without first securing the
                  Collateral Agent's written consent, except as provided in
                  section 6;

         (d)      agrees that if any of the Borrower's rights in the Personal
                  Property Collateral are voluntarily or involuntarily
                  transferred, whether by sale, creation of a security interest,
                  attachment, levy, garnishment or other judicial process, other
                  than as expressly contemplated by section 6 hereof, without
                  the written consent of the Collateral Agent, such transfer
                  shall constitute a default by the Borrower under the terms of
                  this Instrument;

         (e)      authorizes the Collateral Agent to file, in the jurisdiction
                  where this Instrument will be given effect, financing
                  statements covering the Personal Property Collateral and at
                  the request of the Collateral Agent, the Borrower shall join
                  the Collateral Agent in executing one or more of such
                  financing statements pursuant to the Uniform Commercial Code
                  in a form satisfactory to the Collateral Agent and the
                  Borrower shall pay the cost of filing the same in all public
                  offices at any time and from time to time wherever the
                  Collateral Agent deems filing or recording of any financing
                  statements or of this Instrument to be desirable or necessary;
                  and

         (f)      acknowledges that the Borrower, as of the date hereof, has
                  joined the Collateral Agent in the execution of one or more
                  Uniform Commercial Code financing statements to be filed to
                  perfect the security interest in the Personal Property created
                  by this Instrument.

         sought in equity or at law).

                  (c)   NO VIOLATION. Neither the execution, delivery and
         performance by the Borrower of the Credit Documents to which it is
         party nor compliance with the terms and provisions thereof (i) will
         contravene any provision of any law, statute, rule, regulation, order,
         writ, injunction or decree of any court or governmental instrumentality
         applicable to the Borrower or its properties and assets, (ii) will
         conflict with or result in any breach of, any of the terms, covenants,
         conditions or provisions of, or constitute a default under, or result
         in the creation or imposition of (or the obligation to create or
         impose) any Lien (other than the Liens of the Security Documents) upon
         any of the property or assets of the Borrower pursuant to the terms of
         any promissory note, bond, debenture, indenture, mortgage, deed of
         trust, credit or loan agreement, or any other material agreement or
         other instrument, to which the Borrower is a party or by which it or
         any of its property or assets are bound or to which it may be subject,
         or (iii) will violate any provision of the charter or other
         organizational document of the Borrower.

                  (d)   GOVERNMENTAL APPROVALS. No order, consent, approval,
         license, authorization, or validation of, or filing, recording or
         registration with, or exemption by, any foreign or domestic
         governmental or public body or authority, or any subdivision thereof,
         is required to authorize or is required as a condition to (i) the
         execution, delivery and performance by the Borrower of any Credit
         Document to which it is a party, or (ii) the legality, validity,
         binding effect or enforceability of any Credit Document to which the
         Borrower is a party, other than filings and recordings necessary to
         establish and perfect the Liens purported to be created pursuant to the
         Security Documents to which the Borrower is a party.

                  (e)   LITIGATION. There are no actions, suits or proceedings
         pending or, to, the knowledge of the Borrower, threatened with respect
         to the Borrower or the Borrower's Project (i) that have, or could
         reasonably be expected to have, a Material Adverse Effect on the
         Borrower's Project or the Borrower, or (ii which question the validity
         or enforceability of any of the Credit Documents, or of any action to
         be taken by the Borrower pursuant to any of the Credit Documents to
         which it is a party.

                  (f)   USE OF PROCEEDS; MARGIN REGULATIONS. The proceeds of all
         Loans to the Borrower for the Project shall be utilized solely to
         finance the costs and expenses of the acquisition and construction of
         the Project. The Borrower hereby represents and warrants that the Loan
         evidenced hereby is a commercial loan and that such Loan is being made
         solely to acquire or carry on a business, professional or commercial


                                       19









<PAGE>   21


         enterprise or activity. Notwithstanding anything to the contrary
         contained herein, no proceeds of any Loans shall be used by the
         Borrower directly or indirectly to purchase or carry Margin Stock, or
         to extend credit to others for the purpose of purchasing or carrying
         any Margin Stock. Neither any Loans, nor the use of the proceeds
         thereof, will violate or be inconsistent with the provisions of
         Regulation G, T, U or X of the Board of Governors of the Federal
         Reserve System. The Borrower is not engaged in the business of
         extending credit for the purpose of purchasing or carrying any Margin
         Stock. At no time would more than 25% of the value of the assets of the
         Borrower or of the Borrower and its consolidated Subsidiaries that are
         subject to any "arrangement" (as such term is used in section 221.2(g)
         of such Regulation U) hereunder be represented by Margin Stock.

                  (g)   FINANCIAL CONDITION. The Borrower has received
         consideration which is the reasonable equivalent value of the
         obligations and liabilities that the Borrower has incurred to the
         Collateral Agent, the Administrative Agent and the Lenders. The
         Borrower now has capital sufficient to carry on its business and
         transactions and all business and transactions in which it is about to
         engage and is now solvent and able to pay its debts as they mature and
         the Borrower owns property having a value, both at fair valuation and
         at present fair salable value, greater than the amount required to pay
         the Borrower's debts; and the Borrower is not entering into the Credit
         Documents with the intent to hinder, delay or defraud its creditors.

                  (h)   TAX RETURNS AND PAYMENTS. The Borrower has (i) filed all
         federal income tax returns and all other material tax returns, domestic
         and foreign, required to be filed by it; and (ii) paid all taxes and
         assessments payable by it which have become due, other than those not
         yet delinquent and except for those contested in good faith. The
         Borrower has established on its books such charges, accruals and
         reserves in respect of taxes, assessments, fees and other governmental
         charges for all fiscal periods as are required by GAAP. The Borrower
         knows of no proposed assessment for additional federal, foreign or
         state taxes for any period, or of any basis therefor, which,
         individually or in the aggregate, taking into account such charges,
         accruals and reserves in respect thereof as the Borrower has made,
         could reasonably be expected to have a Material Adverse Effect.

                  (i)   TITLE TO BORROWER'S PROJECT AND OTHER PROPERTIES, ETC.
         The Borrower has good and marketable title to the Land and good title
         (or valid leasehold interests, in the case of any leased property), in
         the case of all other property, to all of its properties and assets
         free and clear of Liens other than the Liens purported to be created by
         the Security Documents to which the Borrower is a party and Liens
         permitted by this Instrument. Each Draw Request and Notice of Borrowing
         made on behalf of the Borrower pursuant to the Credit Agreement in
         connection with the incurrence of Loans by the Borrower shall
         constitute the Borrower's representation and warranty to the Lenders,
         the Administrative Agent, the Trustee and the Collateral Agent that (i)
         all completed construction is substantially in accordance with the
         Plans and Specifications, and (ii) all construction and other costs and
         expenses for the payment of which the Lenders have previously advanced
         Loans to the Borrower have in fact been paid.

                  (j)   LAWFUL OPERATIONS, ETC. All necessary federal, state and
         local governmental licenses, registrations, certifications, permits and
         authorizations currently required by law to be obtained in order to
         permit the Borrower to construct and operate the Borrower's Project and
         to operate its business, have been obtained by the Borrower (or by the
         Company on its behalf) and are in full force and effect, except for any
         such authorizations which are not currently so required and which, in
         the judgment of the Borrower, can be obtained by the Borrower (or by
         the Company on its behalf) without undue difficulty prior to the time
         so required. The Borrower (i) is in full compliance with all material
         requirements imposed by law, regulation or rule, whether federal, state
         or local, which are applicable to it, its operations, the Borrower's
         Project or its other properties and assets, including without
         limitation, applicable requirements of Environmental Laws, except for
         any failure to obtain and maintain in effect, or noncompliance, which,
         individually or in the aggregate, could not reasonably be expected to
         result in any substantial delay in construction of the Borrower's
         Project or have a Material Adverse Effect. The Improvements, when
         constructed, will comply with all Legal Requirements affecting the
         Improvements or the Premises.

                  (k)   COMPLIANCE WITH ERISA. Compliance by the Borrower with
         the provisions hereof and Loans contemplated hereby will not involve
         any prohibited transaction within the meaning of ERISA or section 4975
         of the Code.

                  (l)   TRUE AND COMPLETE DISCLOSURE. All factual information
         (taken as a whole) heretofore or contemporaneously furnished by or on
         behalf of the Borrower in writing to the Administrative Agent or any
         Lender for purposes of or in connection with this Instrument or any
         transaction contemplated herein is, and all other such factual
         information (taken as a whole) hereafter furnished by or on behalf of
         the Borrower in writing to any Lender will be, true and accurate in all
         material respects on the date as of which such information is dated or
         certified and not incomplete by omitting to state any material fact
         necessary to make such information (taken as a whole) not misleading at
         such time in light of the circumstances under which such information
         was provided, except that any such future information consisting of
         financial projections prepared by management of the Borrower is only
         represented herein as being based on good faith estimates and
         assumptions believed by such persons to be reasonable at the time made,
         it being recognized by the Lenders that such projections as to future
         events are not to be viewed as facts and that actual results during the
         period or periods covered by any such projections may differ materially
         from the projected results. There is no fact known to the Borrower
         which has, or could reasonably be expected to have, a Material Adverse
         Effect on the Borrower which has not theretofore been disclosed in
         writing to the Lenders.

         16.      CONSTRUCTION AND OTHER PARTICULAR COVENANTS OF THE BORROWER.
The Borrower covenants and agrees that from the date hereof until the Loans made
to the Borrower with respect to the Borrower's Project are paid in full:

                  (a)   CONSTRUCTION OF THE BORROWER'S PROJECT. (i) The Borrower
         will cause construction of the Improvements to the Borrower's Project
         to be commenced within 60 days of the date hereof and carried on
         continuously and to be 100% completed, Lien free and ready for
         occupancy within 15 months of the date of the initial Borrowing by the
         Borrower for the Project, subject to any extension of the maturity date
         of the Loans evidenced hereby pursuant to section 2.7(a) of the Credit
         Agreement (such time, including any such extension, the "COMPLETION
         DATE"), time being of the essence.

                  (ii)  The Borrower's Project will be constructed strictly in
         accordance with the Borrower's Plans and Specifications (as modified
         from time to time in accordance with the Credit Agreement), and all
         applicable Legal Requirements. The Borrower's Project will be
         constructed entirely on the Premises and will not encroach upon or
         overhang any easement, building line or right of way and, when erected,
         will not violate applicable use or other restrictions of record. If, in
         the judgment of the Required Lenders, the Borrower's Project is not in
         substantial conformity with the foregoing, the Required Lenders shall
         have the right to require the Borrower to stop the work and/or effect
         repair or reconstruction of the Borrower's Project in order for the
         Borrower's Project to achieve compliance with the Plans and
         Specifications (as so modified) and all Legal Requirements. Upon notice
         from the Administrative Agent to the Borrower, or the Borrower's
         discovery irrespective of such notice, that the work is not in
         substantial conformity with the Plans and Specifications (as so
         modified) and/or all Legal Requirements, the Borrower shall commence
         correcting the deviation, as promptly as is practicable, and in any
         event within 30 days after the notice or discovery and shall prosecute
         such work diligently to completion, which, in no event, shall be later
         than 60 days after such notice of discovery. No other notice shall be
         required to render such deviation an Event of Default (as hereinafter
         defined) hereunder.

                  (iii) All materials incorporated in such construction will be
         purchased so that absolute ownership and title vest in the Borrower
         upon delivery of such materials to the Borrower's Project.

                  (iv)  No materials, equipment, personal property, or fixtures
         of any kind will be purchased or acquired by the Borrower for
         installation or use in or about the Improvements under any conditional
         sales contract or security agreement or any lease agreement, and all
         such materials, equipment, personal property, and fixtures will be
         fully paid for before payment therefor becomes past due or in any event
         within 45 days after delivery thereof; PROVIDED, HOWEVER, that the
         foregoing shall not (A) apply to amounts withheld and unpaid on account
         of bona fide disputes with the suppliers, or (B) restrict the Borrower
         from incurring Capital



                                       21









<PAGE>   23
Leases or other Indebtedness, or granting purchase money Liens as security
therefor, in accordance with section 16(c).

                  (b)   CONTRACTS AFFECTING THE BORROWER'S PROJECT; NO CHANGES
         IN PLANS AND SPECIFICATIONS, ETC. (i) No change will be made in the
         Plans and Specifications for the Improvements, the terms and conditions
         of the construction contract (the "CONSTRUCTION Contract") for the
         Improvements, or the identity of the General Contractor named therein,
         except in compliance with the requirements of sections 2.3(d) or 6.3(a)
         of the Credit Agreement, without the prior written consent of the
         Administrative Agent (or the Required Lenders, if required under the
         Credit Agreement).

                  (ii)  The Borrower will furnish to the Administrative Agent,
         within 10 days following request, copies of any Tenant Leases or other
         contracts affecting the Borrower's Project.

                  (c)   INDEBTEDNESS.  The Borrower will not create, incur,
         assume, or permit to be outstanding, any Indebtedness of the Borrower,
         OTHER THAN

                        (i)   Indebtedness incurred under the Credit Agreement
                  and the other Credit Documents, whether related to the
                  Project, other Projects of the Borrower, or otherwise;

                        (ii)  Indebtedness in respect of other Projects incurred
                  under the Permanent Credit Agreement or the Supplemental
                  Permanent Credit Agreement, or any of the other agreements or
                  instruments executed and delivered in connection therewith;

                        (iii) Indebtedness incurred to finance up to 100% of the
                  purchase price of equipment or vehicles to be used in
                  connection with the Project, and Capitalized Lease Obligations
                  relating to equipment or vehicles to be used in connection
                  with the Project, PROVIDED that the aggregate principal amount
                  (or Capitalized Lease Obligation, in the case of a Capital
                  Lease) of all such Indebtedness outstanding at any time does
                  not exceed $250,000; and

                        (iv)  as to any other Project of the Borrower,
                  Indebtedness incurred to finance up to 100% of the purchase
                  price of equipment or vehicles to be used in connection with
                  such Project, and Capitalized Lease Obligations relating to
                  equipment or vehicles to be used in connection with such
                  Project, PROVIDED that the aggregate principal amount (or
                  Capitalized Lease Obligation, in the case of a Capital Lease)
                  of all such Indebtedness related to such Project outstanding
                  at any time does not exceed $250,000.

                  (d)   INSPECTION, ETC. (i) The Administrative Agent and the
         Lenders will have the right to cause the Borrower's Project (and all
         records, books and contracts of the Borrower with respect thereto) to
         be inspected from time to time during or after construction. The
         Borrower will furnish to the Administrative Agent and the Lenders any
         information regarding the Borrower's business affairs and financial
         condition as the Administrative Agent or any Lender may, from time to
         time, request.

                  (ii)  Without limitation of the foregoing, the Borrower will
         allow the Administrative Agent and the Lenders and their
         representatives and agents, at all times during construction: (i) the
         right of entry and free access to the site of the Improvements; (ii)
         the right to inspect all work done, labor performed and materials
         furnished in and about the Improvements; and (iii) to require to be
         replaced or otherwise corrected any material or work that does not
         substantially comply with the Plans and Specifications.

                  (e)   REIMBURSEMENT OF COSTS AND EXPENSES. (i) The Borrower
         will reimburse the Administrative Agent, the Collateral Agent and the
         Lenders promptly for all costs and expenses incurred by any of them in
         connection with this Instrument and the Loans, including but not
         limited to the costs of title insurance policies, title examinations,
         recording fees, surveys, appraisal fees, inspection fees, reasonable
         attorneys' fees and out-of-pocket expenses, all of which the
         Administrative Agent is authorized to deduct from the proceeds of Loans
         to the Borrower.



                                       22











<PAGE>   24


                  (ii)  In the event extraordinary services are required by the
         Administrative Agent or any Lender for inspections, appraisals, or for
         securing estimates of costs which, in its reasonable judgment are not
         regular or routine, the Borrower will reimburse the Administrative
         Agent and the Lenders therefor, on demand, and the Administrative Agent
         may deduct the reasonable cost and expense thereof from the proceeds of
         Loans to the Borrower.

                  (iii) The Borrower will immediately upon demand reimburse any
         Lender for the cost and expense of any appraisal of the Borrower's
         Project obtained by such Lender on or after the date hereof if such
         appraisal is obtained by such Lender pursuant to the requirements of
         any law, statute, rule, regulation, interpretive ruling, opinion, or
         directive of any state or federal governmental agency or unit
         governing, regulating, or controlling the activities of such Lender,
         whether now existing or hereafter enacted.

                  (f)   LIEN WAIVERS, ETC. The Borrower will furnish or cause to
         be furnished to the Title Company which issues the loan policy of title
         insurance covering this Instrument, and to the Collateral Agent, any
         evidence, lien waivers, or affidavits required by the Title Company if
         any liens of contractors, subcontractors or materialmen would appear on
         the endorsement to be issued with respect to the applicable Title
         Policy covering any disbursement of Loan proceeds.

                  (g)   OPERATING ACCOUNT. (i) If required to do so by the
         Administrative Agent, the Borrower shall maintain with the Lender which
         is the Administrative Agent (or an Affiliate thereof designated by such
         Lender) a general deposit and disbursing account (the "OPERATING
         ACCOUNT"). All disbursements of Loan proceeds to or for the benefit of
         the Borrower shall be made as provided in the Credit Agreement.

                  (ii)  The Borrower authorizes the Administrative Agent to make
         disbursements of Loan proceeds by debiting the Operating Account to pay
         any principal or interest upon the Notes when and as same shall become
         due under the terms thereof, and Borrower agrees that such
         disbursements shall constitute Loans under this Instrument and the
         Notes. The Borrower also authorizes the Administrative Agent to charge
         the Borrower's Operating Account for any amounts payable by the
         Borrower under any of the Credit Documents to which the Borrower is a
         party.

                  (h)   NOTICE OF EVENT OF DEFAULT. The Borrower shall notify
         the Administrative Agent, in writing, within five days of the
         occurrence thereof of any Event of Default (as hereinafter defined) or
         of any event which, with notice or lapse of time or both, would become
         an Event of Default.

                  (i)   SIGNAGE AND PUBLICITY OF FINANCING. The Administrative
         Agent may, without out-of-pocket expense to the Borrower, at any time
         following the commencement of construction, erect on the Premises a
         temporary sign, reasonably acceptable to the Borrower, identifying the
         Project and stating that financing for the Borrower's Project is being
         provided by the Lenders, as represented by the Administrative Agent.
         The Borrower hereby agrees that the Administrative Agent and the
         Lenders may release publicity articles concerning the financing of the
         Borrower's Project.

                  (j)   NOTICES AND ACTIONS UNDER CONSTRUCTION LENDING STATUTES.
         The Borrower will comply from time to time upon the request of the
         Administrative Agent with the requirements of any statutes in effect in
         the jurisdiction in which the Premises are located which do or may give
         the Loans priority over claims of contractors, laborers, materialmen or
         others for labor or other amounts due for work or labor performed, or
         materials furnished, to the Premises, including, without limitation,
         the filing, recording and giving of notices of this Instrument and the
         commencement of work to be financed thereby.

         17.      RIGHT OF SETOFF. In addition to any rights now or hereafter
granted under applicable law or otherwise, and not by way of limitation of any
such rights, upon the occurrence of an Event of Default, each Lender is hereby
authorized at any time or from time to time, without presentment, demand,
protest or other notice of any kind to the Borrower or to any other person, any
such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by such Lender (including, without limitation, by
branches and agencies of such Lender wherever located) to or for the credit or

the Notes or any other Credit Documents to which the Borrower is a party,
including, without limitation, all interests in Obligations of the Borrower
purchased by such Lender pursuant to section 13.4(b) of the Credit Agreement,
and all other claims of any nature or description arising out of or connected
with this Note or any other Credit Document, irrespective of whether or not such
Lender shall have made any demand hereunder and although said Obligations,
liabilities or claims, or any of them, shall be contingent or unmatured.

         18.  TRANSFER AND EXCHANGE OF NOTES. Whenever any Note or Notes of the
Borrower shall be surrendered for exchange or for transfer, the Borrower will
execute and deliver in exchange therefor a new Note or Notes, in whatever
appropriate denominations are requested.

         19.  EVENTS OF DEFAULT. Any of the following specified events (each an
"EVENT OF Default") shall constitute an Event of Default under this Instrument:

              (a)  PAYMENTS: the Borrower shall (i) default in the payment when
         due of any principal of the Loans made to the Borrower for the Project
         or any other Project of the Borrower (whether at maturity, on a
         required prepayment or otherwise); or (ii) default, and such default
         shall continue for five or more days, in the payment when due of any
         interest on such Loans or any other amounts owing hereunder or under
         any other Credit Document; or

              (b)  REPRESENTATIONS, ETC.: any representation, warranty or
         statement made by the Borrower herein or in any other Credit Document
         or in any statement or certificate delivered or required to be
         delivered pursuant hereto or thereto shall prove to be untrue in any
         material respect on the date as of which made or deemed made; or

              (c)  CERTAIN NEGATIVE COVENANTS: the Borrower shall default
         in the due performance or observance by it of any term, covenant or

         Instrument; or

              (d)  OTHER COVENANTS: the Borrower shall default in the due

         default shall not be remedied within 30 days after the earlier of (i)
         an officer (or similar official) of the Borrower obtaining actual
         knowledge of such default or (ii) the Borrower receiving written notice
         of such default from the Collateral Agent or the Required Lenders (any
         such notice to be identified as a "notice of default " and to refer
         specifically to this paragraph); PROVIDED, that in the case of any
         default referred to in this paragraph not involving a monetary
         obligation, the 30-day period referred to above may be extended by
         written notice from the Borrower (or the Company on its behalf) to the
         Collateral Agent delivered not later than 10 days following the giving
         of any notice referred to in the preceding clause (ii), for an
         additional period of up to 60 days, if (x) such notice from the
         Borrower (or the Company on its behalf) includes a certification that
         unavoidable delays or other circumstances are such that such default
         cannot be remedied within such 30-day period, but that such default can
         be remedied within the time period specified for such extension, and
         (y) throughout the period of such requested extension the Borrower is
         diligently and continuously taking all reasonable actions to remedy
         such default (it being understood that if the Borrower shall cease or
         abandon such efforts to remedy the default, such extension period shall
         immediately and automatically terminate); or

              (e)  EVENT OF DEFAULT UNDER CREDIT AGREEMENT: any Event of
         Default under and as defined in the Credit Agreement shall occur and be
         continuing beyond any grace period (if any) provided therein,
         regardless of whether such Event of Default does or does not relate to
         any events or circumstances which constitute, or which with notice or
         lapse of time, or both, would constitute, an Event of Default under
         this Instrument; or

              (f)  PROJECT TAKE-OUT COMMITMENT, ETC.: the commitment issued by
         the Permanent Lender or the Supplemental Permanent Lender to the
         Borrower with respect to the Project shall, for any reason, cease to be
         in full force and effect, with availability, subject to the terms and
         conditions contained in such commitment, of loans thereunder sufficient
         to enable the Borrower to refinance all Loans for the Project which


                                       24
<PAGE>   26
         may be made under the Credit Agreement; or the Project Take-Out
         Agreement with respect to the Project shall, for any reason, cease to
         be in full force and effect; or

              (g)  ACCELERATION OF OTHER INDEBTEDNESS: the Borrower shall (A)
         default in any payment with respect to any Indebtedness (other than the
         Loans of the Borrower for the Project or any other Project of the
         Borrower) having an unpaid principal amount (or Capitalized Lease
         Obligation, in the case of any Capital Lease) of $100,000 times the
         number of Projects at the time being financed by the Borrower under the
         Credit Agreement, or greater, or (B) default in the observance or
         performance of any agreement, covenant or condition relating to any
         such Indebtedness or contained in any instrument or agreement
         evidencing, securing or relating thereto (and all grace periods
         applicable to such observance, performance or condition shall have
         expired), and (1) such default shall continue after the applicable
         grace period, if any, specified in the agreement or instrument relating
         to such Indebtedness, and (2) the holder or holders of such
         Indebtedness (or a trustee or agent on behalf of such holder or
         holders) shall accelerate the maturity of all or any portion thereof,
         or shall demand payment thereof in the case of any such Indebtedness
         which is payable upon demand or after demand and notice, and such
         acceleration or demand for payment shall not have been rescinded prior
         to the acceleration of any of the Loans or other Obligations pursuant
         to section 10.2 of the Credit Agreement; or

              (h)  LIEN OF THIS INSTRUMENT: this Instrument, after recording in
         the real property records in the jurisdiction in which the Premises are
         located, shall for any reason not be effective to establish and

         lien on the Premises and the Improvements, subject to no other liens or
         security interests; or

              (i)  BANKRUPTCY, ETC.: any of the following shall occur: (A) the
         Borrower shall commence a voluntary case concerning itself under Title

         conservator or liquidator (collectively, a "CONSERVATOR") of itself or
         the Project or all or any substantial portion of its property) any
         other proceeding under any reorganization, arrangement, adjustment of

         whether now or hereafter in effect relating to the Borrower; or (E) any
         such proceeding is commenced against the Borrower to the extent such

         bankrupt; or (G) any order of relief or other order approving any such
         case or proceeding is entered; or (H) the Borrower suffers any
         appointment of any conservator or the like for it or the Project or any
         substantial part of its property which continues undischarged or

         20.  REMEDIES. If an Event of Default, under and as defined in
section 19 of this Instrument, has occurred and is continuing:

              (a) The Collateral Agent, acting by or through the Trustee, the
         Administrative Agent and the Lenders may exercise any one or more of
         the remedies specified in section 10.2 of the Credit Agreement or
         otherwise available at law or in equity.

              (b)   To the extent permitted by applicable law, the Collateral
         Agent or Trustee may enter upon the Property Covered by this Instrument
         or any portion thereof and may exclude the Borrower therefrom; and
         having and holding the same, may use, operate, manage, and control the
         Property Covered by this Instrument and conduct business in connection
         therewith, including, without limitation the continuation of the
         construction of the Improvements if not previously completed, either
         personally or by its superintendents, managers, agents, servants,
         attorneys or receivers; and upon every such entry, the Collateral Agent
         or Trustee, at the expense of the Borrower and from time to time, may
         maintain the Property Covered by this Instrument and may insure


                                       25
<PAGE>   27
         and reinsure the same, as may seem to the Collateral Agent or Trustee
         to be necessary or advisable; and, at the expense of the Borrower and
         from time to time, the Collateral Agent may make all repairs, renewals,
         replacements, alterations, additions, betterments and improvements
         thereto and thereon, as to the Collateral Agent or Trustee may seem
         necessary or advisable, and if the construction of the Improvements has
         not been completed, may cause such construction to be continued to
         completion or to such stage of completion as the Collateral Agent or
         Trustee considers necessary or advisable; and in every such case the
         Collateral Agent or Trustee shall have the right to carry on the
         construction thereof, enter into, terminate, cancel and/or enforce
         contracts or Tenant Leases related thereto, manage and operate the
         Property Covered by this Instrument and carry on the business thereof,
         and otherwise exercise all rights which the Borrower might otherwise
         have with respect thereto, in the name of the Borrower or otherwise, as
         the Collateral Agent or Trustee shall deem best or advisable; and the
         Collateral Agent or Trustee shall be entitled to collect all Rents,
         earnings, revenues, issues, profits and income of the Property Covered
         by this Instrument, awards made for the taking of or injury to the
         Property Covered by this Instrument through eminent domain or
         otherwise, including awards or damages for change of grade, and also
         return premiums or other payments upon insurance, and said Rents,
         earnings, revenues, issues, profits and income, awards, damages,
         premiums and payments are hereby assigned to the Collateral Agent or
         Trustee, and after deducting the expenses and costs of conducting the
         business thereof and of all betterments, additions, alterations,
         replacements, repairs and for taxes, assessments, insurance and prior
         or other charges upon or with respect to the Property Covered by this
         Instrument or any portion thereof, as well as just and reasonable
         compensations for the services of all counsel, agents, employees,
         receivers and other persons properly engaged or employed, the
         Collateral Agent or Trustee shall apply the proceeds as provided in
         section 21.

                  (c)   To the extent permitted by applicable law, the Trustee
         is hereby authorized and empowered by the Borrower to sell the Property
         Covered by this Instrument in such manner as may be prescribed by law,
         by advertisement and public sale as provided by the laws of the
         jurisdiction in which the Real Property is located, or to foreclose
         this Instrument by judicial proceedings and sell the Property Covered
         by this Instrument pursuant to such proceedings as permitted by
         applicable law. Upon the occurrence of an Event of Default, the
         Borrower assents to the passage of a decree for the sale of the
         Property Covered by this Instrument and further authorizes the Trustee
         to sell the Property Covered by this Instrument. The Borrower does
         hereby authorize the Trustee to sell the Property Covered by this
         Instrument together or in lots or parcels, as to the Trustee shall seem
         expedient, and to execute and deliver to the purchaser or purchasers of
         such property good and sufficient deeds thereof with covenants of
         general, special or limited warranty or such other instruments of
         conveyance, assignment or transfer as the Trustee may deem appropriate.
         Payment of the purchase price to the Trustee shall satisfy the
         obligation of the purchaser at any such sale therefor, and he shall not
         be bound to look after the application thereof. The Trustee shall cause
         notice of any such sale to be mailed to the Borrower; but, except as
         otherwise provided by any applicable provision of law, failure so to
         mail any such notice shall not affect the validity of any such sale. If
         the Collateral Agent, acting on behalf of any or all of the holders of
         the Notes or other Indebtedness secured hereby, or any or all such
         holders acting on their own behalf, is the highest bidder, the
         Collateral Agent or such holders, as the case may be, may purchase at
         any sale or sales (whether statutory foreclosure or public sale or
         sales conducted as hereinabove authorized) and may, in paying the
         purchase price, turn in the Note or Notes or other Indebtedness secured
         hereby held by them, in lieu of cash, up to the entire amount owing
         thereunder, whether for principal, interest or other amounts, which
         amount as so designated as being turned over shall be considered
         distribution of the proceeds of such sale. The provisions set forth
         above as to public sale or sales in lieu of statutory foreclosure are
         not intended as an exclusive method of foreclosure hereunder or to
         deprive the Collateral Agent or Trustee of any other legal or equitable
         remedy available under applicable law. Accordingly, it is specifically
         agreed that the remedy of foreclosure by the Trustee's sale as
         hereinabove provided for shall be cumulative and shall not in any wise
         be construed as an exclusive remedy, and the Collateral Agent or
         Trustee shall be fully entitled to a statutory court foreclosure and to
         avail itself of any and all other legal or equitable remedies available
         under the laws of the jurisdiction in which the Real Property is
         located.

                  (d)   The Borrower hereby authorizes the Collateral Agent or
         Trustee to demand and receive, in the place and stead of the Borrower,
         all amounts that may become due under any and each Tenant Lease,
         rental, contract, easement and other right of the Borrower pertaining
         or in any way relating to the Property Covered by this Instrument or
         any part thereof, and, when received, to apply the same to the costs
         and expenses


                                       26
<PAGE>   28


         incurred by the Collateral Agent or Trustee incurred hereunder and to
         the Indebtedness secured hereby. No demand for, and no receipt or
         application of any such amount shall be deemed to minimize, subordinate
         or affect in any way the lien hereof and rights hereunder of the
         Collateral Agent or any rights of a purchaser of any portion of the
         Property Covered by this Instrument at any foreclosure or other sale
         hereunder, as against the person from whom the amount was demanded or
         received, or his executors, administrators, successors or assigns, or
         anyone claiming under such Tenant Lease, rental, contract or other
         right.

                  (e)   The Collateral Agent, acting by or through the Trustee,
         may exercise all rights and remedies granted by law and more
         particularly the Uniform Commercial Code, including, but not limited
         to, the right to take possession of the Personal Property Collateral,
         and for this purpose may peaceably enter upon any premises on which any
         or all of the Personal Property Collateral is situated, without being
         deemed guilty of trespass and without liability for damages thereby
         occasioned, and take possession of and operate the Personal Property
         Collateral or remove it therefrom; the Collateral Agent or Trustee
         shall have the further right to take any action it deems necessary,
         appropriate or desirable, at its option and in its discretion, to
         repair, refurbish or otherwise prepare the Personal Property Collateral
         for sale, lease or other use or disposition and to sell at public or
         private sales or otherwise dispose of, lease or utilize the Personal
         Property Collateral and any part thereof in any manner authorized or
         permitted by law and to apply the proceeds thereof toward payment of
         any costs and expenses, including reasonable attorneys' fees and legal
         expenses, to the extent permitted by law, thereby incurred by the
         Collateral Agent or Trustee and toward payment of the Indebtedness and
         all other indebtedness described in this Instrument, in such order and
         manner as may be provided in the Credit Agreement or this Instrument or
         in the event such provisions are not applicable in such order and
         manner as the Collateral Agent or Trustee may elect.

         21.      COSTS OF ENFORCEMENT; APPLICATION OF PROCEEDS; BORROWER LIABLE
FOR DEFICIENCY, ETC. (a) In case of (i) foreclosure of this Instrument in any
court of law or equity, whether or not any order or decree shall have been
entered therein, and to the extent permitted by law, a reasonable sum shall be
allowed for attorney's fees of the Collateral Agent or Trustee in such
proceedings, for stenographer's fees and for all moneys expended for documentary
evidence and the cost of a complete abstract of title and title report for the
purpose of such foreclosure, such sums to be secured by the lien hereunder, and,
to the extent permitted by law, there shall be included in any judgment or
decree foreclosing this Instrument and be paid out of such rents, issues and
profits or out of the proceeds of any sale made in pursuance of any such
judgment or decree, or (ii) any other realization by the Collateral Agent or
Trustee upon or with respect to the Property Covered by this Instrument or any
part or portion thereof, the proceeds thereof shall be applied as follows:

                  (A)   first, to the payment or reimbursement of the Collateral
         Agent or Trustee for all costs and expenses of such suit or suits or
         other enforcement activities of the Collateral Agent or Trustee,
         including, but not limited to, the costs of advertising, sale and
         conveyance, including attorneys', solicitors' and stenographers' fees,
         if permitted by law, outlays for documentary evidence and the cost of
         such abstract, examination of title and title report;

                  (B)   second, to the extent proceeds remain after the
         application pursuant to preceding clause (A), to reimburse the
         Collateral Agent for all moneys advanced by the Collateral Agent or
         Trustee, if any, for any purpose authorized in this Instrument with
         interest at the Default Rate;

                  (C)   third, to the extent proceeds remain after the
         application pursuant to preceding clause (B), an amount equal to the
         outstanding Indebtedness shall be applied by the Collateral Agent or
         Trustee to the Indebtedness secured hereby in such order as may be
         provided in the Credit Agreement; and

                  (D)   fourth, to the extent remaining after the application
         pursuant to the preceding clauses (A), (B) and (C) and payment in full
         of the Indebtedness hereby secured, to the Borrower or to whomever may
         be lawfully entitled to receive such payment.

         (b)      It is understood that the Borrower shall remain liable to the
extent of any deficiency between (x) the amount of the proceeds of the Property
Covered by this Instrument and the amount of the sum referred to in the
foregoing clauses (A) and (B) and (y) the aggregate outstanding amount of the
Indebtedness secured hereby.

         22.      RECEIVER. In the event an action shall be instituted to
foreclose this Instrument, or prior to foreclosure but after default, the
Collateral Agent or Trustee shall be entitled to the appointment of a receiver
of the rents, issues and profits of the Property Covered by this Instrument as a
matter of right, with power to collect the rents, issues and profits of the
Property Covered by this Instrument due and becoming due during the period of
default and/or the pendency of such foreclosure suit to and including the date
of confirmation of the sale under such foreclosure and during the redemption
period, if any, after such confirmation, such rents, issues and profits being
hereby expressly assigned and pledged as security for the payment of the
Indebtedness secured by this Instrument without regard to the value of the
Property Covered by this Instrument or the solvency of any person or persons
liable for the payment of the Indebtedness and regardless of whether the
Collateral Agent or Trustee has an adequate remedy at law. The Borrower for
itself and for any subsequent owner hereby waives any and all defenses to the
application for a receiver as above provided and hereby specifically consents to
such appointment, but nothing herein contained is to be construed to deprive the
holder of this Instrument of any other right or remedy or privilege it may now
have under the law to have a receiver appointed. The provision for the
appointment of a receiver and the assignment of such rents, issues and profits
is made an express condition upon which the Loans hereby secured are made. In
such event, the court shall at once on application of the Collateral Agent,
Trustee or their attorneys in such action, appoint a receiver to take immediate
possession of, manage and control the Property Covered by this Instrument, for
the benefit of the holder or holders of the Indebtedness and of any other
parties in interest, with power to collect the rents, issues and profits of the
Property Covered by this Instrument during the pendency of such action, and to
apply the same toward the payment of the several obligations herein mentioned
and described, notwithstanding that the same or any part thereof is occupied by
the Borrower or any other person. The rights and remedies herein provided for
shall be deemed to be cumulative and in addition to and not in limitation of
those provided by law and if there be no receiver so appointed, the Collateral
Agent or Trustee may proceed to collect the rents, issues and profits from the
Property Covered by this Instrument. From any such rents, issues, and profits
collected by the receiver or by the Collateral Agent or Trustee prior to a
foreclosure sale, there shall be deducted the cost of collection thereof and the
expenses of operation of the Property Covered by this Instrument, including but
not limited to real estate commissions, receiver's fee and the reasonable fees
of its attorney, if any, and the Collateral Agent's or Trustee's attorney's
fees, if permitted by law, and court costs, the remainder to be applied against
the Indebtedness. In the event the rents, issues and profits are not adequate to
pay all tax and other expenses of operation, the Collateral Agent or Trustee
may, but is not obligated to, advance to any receiver the amounts necessary to
operate, maintain and repair, if necessary, the Property Covered by this
Instrument and any such amounts so advanced, together with interest thereon at
the Default Rate from and after the date of advancement, shall be secured by
this Instrument and have the same priority of collection as the principal of the
Indebtedness secured hereby.

         23.      LIABILITY OF BORROWER NOT AFFECTED. No sale of the Property
Covered by this Instrument, no forbearance on the part of the Collateral Agent,
no extension of the time for the payment of the Indebtedness and no change in
the terms of the payment thereof consented to by the Collateral Agent or Trustee
shall in any way whatsoever operate to release, discharge, modify, change or
affect the original liability of the Borrower hereunder or the original
liability of the Borrower or any other obligor under any of the Indebtedness,
either in whole or in part. No waiver by the Collateral Agent or Trustee of any
breach of any covenant of the Borrower herein contained shall be construed as a
waiver of any subsequent breach of the same or any other covenant herein
contained. The failure of the Collateral Agent, Trustee and/or the Lenders to
exercise the option for acceleration of maturity and/or foreclosure (including
sale under power of sale hereunder) following any default as aforesaid or to
exercise any other option granted to the Collateral Agent or Trustee hereunder
in any one or more instances, or the acceptance by the Collateral Agent, Trustee
and/or the Lenders of partial payments hereunder shall not constitute a waiver
of any such default, nor extend or affect the grace period, if any, but such
option shall remain continuously in force with respect to any unremedied or
uncured default. Acceleration of maturity once claimed hereunder by the
Collateral Agent or Trustee may, at the option of the Collateral Agent or
Trustee, be rescinded by written acknowledgment to that effect by the Collateral
Agent or Trustee, but the tender and acceptance of partial payments alone shall
not in any way affect or rescind such acceleration of maturity, or extend or
affect the grace period, if any. The Collateral Agent or Trustee may pursue any
of its rights without first exhausting its rights hereunder and all rights,
powers and remedies conferred upon the Collateral Agent or Trustee herein are in
addition to each and every right which the Collateral Agent or Trustee may have
hereunder at law or equity and may be enforced concurrently therewith.

         24.      PARTICIPATION IN PROCEEDINGS. If any action or proceeding be
commenced, to which action or proceeding the Collateral Agent or Trustee is made
a party by reason of the execution of this Instrument or the Indebtedness, or in
which it becomes necessary to defend or uphold the lien of this Instrument, or
the priority thereof


                                       28

or possession of the Property Covered by this Instrument, or otherwise to
perfect the security hereunder, or in any suit, action, legal proceeding or
dispute of any kind in which the Collateral Agent or Trustee is made a party or
appears as party plaintiff or defendant, affecting the interest created herein,
or the Property Covered by this Instrument, including, but not limited to,
bankruptcy, probate and administration proceedings, foreclosure of this
Instrument or any condemnation action involving the Property Covered by this
Instrument, all sums paid by the Collateral Agent or Trustee for the expense of
any litigation to prosecute and defend the rights and liens created hereby shall
be paid by the Borrower, to the extent permitted by applicable law, together
with interest thereon from the date of payment at the Default Rate. Any such sum
and the interest thereon shall be immediately due and payable upon demand and be
secured hereby, having the benefit of the lien hereby created, as a part hereof
and its priority.

         25.      REMEDIES CUMULATIVE. Each remedy or right of the Collateral
Agent or Trustee shall not be exclusive of but shall be in addition to every
other remedy or right now or hereafter existing at law or in equity. No delay in
the exercise or omission to exercise any remedy or right accruing on any default
shall impair any such remedy or right or be construed to be a waiver of any such
default or acquiescence therein, nor shall it affect any subsequent default of
the same or of a different nature. Every such remedy or right may be exercised
concurrently or independently and when and as often as may be deemed expedient
by the Collateral Agent or Trustee.

         26.      COLLATERAL AGENT SUBROGATED TO PRIOR LIENS PAID OUT OF LOAN
PROCEEDS. Should the proceeds of any Loans made by any Lender to the Borrower,
the repayment of which is hereby secured, or any part thereof, or any amount
paid out or advanced by the Collateral Agent, Trustee or any Lender, be used
directly or indirectly to pay off, discharge or satisfy, in whole or in part,
any prior lien or encumbrance upon the Property Covered by this Instrument or
any part thereof, then the Collateral Agent shall be subrogated to such other
liens or encumbrances and upon any additional security held by the holder
thereof and shall have the benefit of the priority of all of the same.

         27.      FURTHER ASSURANCES. The Borrower shall execute, acknowledge
and deliver any and all such further acts, conveyances, documents, mortgages and
assurances as the Collateral Agent or Trustee may reasonably require for
accomplishing the purpose hereof forthwith upon the request of the Collateral
Agent or Trustee, whether in writing or otherwise. The Borrower, within 10 days
upon request by mail, shall furnish a written statement duly acknowledged of the
amount due upon this Instrument and the Indebtedness (both unpaid principal and
accrued interest) and whether any offset or defenses exist against the
Indebtedness, and any other information which might reasonably be requested in
connection with the sale of the Indebtedness, or any portion thereof or interest
therein, to any third party, or an audit of the Collateral Agent or Trustee, and
which may be relied on for such purposes.

         28.      BORROWER'S OBLIGATIONS ABSOLUTE. The lien of this Instrument
and the obligations of the Borrower hereunder shall be absolute and
unconditional and shall remain in full force and effect without regard to, and
shall not be released, suspended, discharged, terminated or otherwise affected
by, any circumstance or occurrence whatsoever, including, without limitation:

                  (a)   any renewal, extension, amendment or modification of, or
         addition or supplement to or deletion from other Credit Documents, or
         any other instrument or agreement referred to therein, or any
         assignment or transfer of any thereof;

                  (b)   any waiver, consent, extension, indulgence or other
         action or inaction under or in respect of any such agreement or
         instrument or this Instrument except as expressly provided in such
         renewal, extension, amendment, modification, addition, supplement,
         assignment or transfer;

                  (c)   any furnishing of any additional security to the
         Collateral Agent or its assignee or any acceptance thereof or any
         release of any security by the Collateral Agent or its assignee;

                  (d)   any limitation on any person's liability or obligations
         under any such instrument or agreement or any invalidity or
         unenforceability, in whole or in part, of any such instrument or
         agreement or any term thereof; or

                  (e)   any bankruptcy, insolvency, reorganization, composition,
         adjustment, dissolution, liquidation or other like proceeding relating
         to the Borrower, any other Credit Party or any Subsidiary of any
         thereof, or


                                       29








<PAGE>   31


         any action taken with respect to this Instrument by any trustee or
         receiver, or by any court, in any such proceeding, whether or not the
         Borrower shall have notice or knowledge of any of the foregoing.

         29.      NOTICES. Wherever notices may appropriately be given under
this Instrument, such notices shall be in writing and shall always be treated as
having adequately been given if:

                  (a) when intended for the Borrower, five days after dispatch
         by Registered or Certified Mail return receipt requested, addressed to
         the mailing address, as set out herein or to such other address or to
         such other person, as the Borrower may from time to time, designate in
         writing; or

                  (b) when intended for the Collateral Agent or Trustee, five
         days after dispatch by Registered or Certified Mail return receipt
         requested, addressed to the mailing address of the Collateral Agent or
         Trustee as set out herein or to such other address or to such other
         person as the Collateral Agent may from time to time designate in
         writing.

         30.      DISCHARGE OF INSTRUMENT; RELEASE OF PROPERTY. (a) After the
termination of the Total Commitment and when all Loans and other Obligations
have been paid in full, or earlier in accordance with the provisions of section
13.9 of the Credit Agreement, this Instrument shall terminate, and the
Collateral Agent, at the request and expense of the Borrower, will execute and
deliver to the Borrower a proper instrument or instruments (including Uniform
Commercial Code termination statements on form UCC-3) acknowledging the
satisfaction and termination of this Instrument, and will duly assign, transfer
and deliver to the Borrower (without recourse and without any representation or
warranty) such of the Personal Property Collateral as may be in the possession
of the Collateral Agent and as has not theretofore been sold or otherwise
applied or released pursuant to this Instrument. In case of failure of the
Collateral Agent to promptly so release this Instrument, all claims for
statutory penalties and damages are hereby waived.

         (b)      So long as no payment default on any of the Indebtedness
secured hereby is in existence or would exist after the application of proceeds
as provided below, the Collateral Agent shall, at the request of the Borrower,
release any or all of the Property Covered by this Instrument, PROVIDED that (x)
such release is permitted by the terms of clause (G) of section 6 of this
Instrument, or section 9.2 of the Credit Agreement) or otherwise has been
approved in writing by the Required Lenders (or all of the Lenders, if required
by section 13.13 of the Credit Agreement) and (y) if required pursuant to the
provisions of section 5.2 of the Credit Agreement, the proceeds of such
Collateral are applied to the prepayment of the Loans for the Project.

         (c)      At any time that the Borrower desires that the Collateral
Agent take any action to give effect to any release of any or all of the
Property Covered by this Instrument pursuant to the foregoing paragraph (a) or
(b), it shall deliver to the Collateral Agent a certificate signed by a
principal executive officer stating that the release of the respective portion
of or all of the Property Covered by this Instrument is permitted pursuant to
paragraph (a) or (b). In the event that any part of the Property Covered by this
Instrument is released as provided in paragraph (a), the Collateral Agent, at
the request and expense of the Borrower, will duly release such part of the
Property Covered by this Instrument and assign, transfer and deliver to the
Borrower (without recourse and without any representation or warranty) such of
the part of the Property Covered by this Instrument as is then being (or has
been) so sold and as may be in the possession of the Collateral Agent and has
not theretofore been released pursuant to this Instrument. The Collateral Agent
shall have no liability whatsoever to any Lender as the result of any release of
all or any part of the Property Covered by this Instrument by it as permitted by
this section. Upon any release of all or any part of the Property Covered by
this Instrument pursuant to paragraph (a) or (b), none of the Collateral Agent
or any of the Lenders shall have any continuing right or interest in the same,
or the proceeds thereof.

         31.      SUBSTITUTE TRUSTEE. Collateral Agent shall have, and is hereby
granted by Borrower with a warranty of further assurances, the irrevocable power
to appoint a substitute trustee or trustees hereunder and to remove any or all
trustees hereunder from time to time without notice and without specifying any
reason therefor, by filing for record a deed of appointment in the office in
which this Deed of Trust is recorded. Such power of removal and appointment may
be exercised as often and whenever Collateral Agent deems it advisable, and the
exercise of such power, no matter how often, shall not result in an exhaustion
of such power. Upon the recordation of each such deed of appointment or removal,
each trustee so appointed shall become fully vested with identically the same
title and estate in and to the Property Covered by This Instrument and with all
the identical rights, powers, trusts and duties hereunder given.

         32.      MISCELLANEOUS. (A) ACKNOWLEDGMENT OF RECEIPT OF COPIES OF
CREDIT DOCUMENTS. The Borrower acknowledges that it has received from the
Collateral Agent without charge a true and correct copy of this Instrument and
each other Credit Document executed and delivered on or prior to the date
hereof.

         (b)      INDEMNIFICATION. The Collateral Agent and its successors and
assigns shall be entitled to all of the benefits of the indemnification
provisions of the Credit Agreement and the other Credit Documents. All of the
terms and provisions of section 13.1 of the Credit Agreement (including any
defined terms used therein) are by this reference thereto hereby incorporated
into this Instrument for the benefit of the Collateral Agent and its successors
and assigns as fully as if written out at length herein, and any references in
such section of the Credit Agreement to the "Company" shall be deemed to refer
to, and constitute obligations of, the Borrower.

         (c)      SUBSEQUENT SERVICES OF COUNSEL TO COLLATERAL AGENT OR TRUSTEE.
To the extent services are required of the Collateral Agent's or Trustee's
counsel after the date hereof, which are normally incident to the closing,
amendment, alteration, and enforcement of this Instrument, and all provisions
herein contained, the Borrower shall, to the extent permitted by law, pay the
reasonable fees therefor, promptly upon the rendering of such a bill and
delivery thereof to the Borrower.

         (d)      NO PARTNERSHIP OR JOINT VENTURE. Neither this Instrument, the
Credit Agreement, the Notes, any other Indebtedness secured hereby, any of the
other Credit Documents, or any of the Designated Hedge Agreements, are intended
or shall be construed as creating a partnership or joint venture between the
Borrower, on the one hand, and the Collateral Agent or any other holder of any
of the Indebtedness, on the other hand; and the relationship of the Borrower and
the Collateral Agent hereunder shall solely be that of borrower and collateral
agent for the holders of the Indebtedness secured hereby.

         (e)      ELECTION OF COLLATERAL AGENT TO SUBORDINATE. At the option of
the Collateral Agent (acting on instructions from all of the Lenders), this
Instrument shall become subject and subordinate in whole or in part (but not in
respect to the priority of entitlement to insurance proceeds or any award in
condemnation) to any or all leases and/or subleases of all or any part of the
Property Covered by this Instrument upon the execution by the Collateral Agent
and recording thereof, at any time hereafter, in the appropriate recorder's
office, a unilateral declaration to that effect.

         (f)      WAIVER OF HOMESTEAD AND EXEMPTION RIGHTS, ETC. To the extent
permitted by law with respect to the Indebtedness secured hereby or any renewals
or extensions thereof, the Borrower waives and renounces any and all homestead
and exemption rights, as well as the benefit of all valuation and appraisement
privileges, and also moratoriums under or by virtue of the constitution and laws
of the jurisdiction in which the Real Property is located or any other state or
of the United States, now existing or hereafter enacted.

         (g)      COVENANTS RUN WITH THE LAND. All the covenants hereof shall
run with the land. Nothing herein contained nor any transaction related hereto
shall be construed or shall so operate, either presently or prospectively, to
require the Borrower to pay interest at a rate greater than is now lawful in
such case to contract for, but shall require payment of interest only to the
extent of such lawful rate.

         (h)      GOVERNING LAW; SUCCESSORS AND ASSIGNS; SEVERABILITY, ETC. This
Instrument shall be construed and enforced according to the laws of the
jurisdiction in which the Real Property is located, and shall be binding upon
the Borrower, its successors and assigns, any subsequent owners of the Property
Covered by this Instrument, and shall inure to the benefit of the Collateral
Agent, Trustee, its successors-in-trust and assigns. Any provision of this
Instrument which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         (i)      NO MODIFICATION. None of the terms and conditions of this
Instrument may be changed, waived, modified or varied in any manner whatsoever
unless in writing duly signed by the Borrower and the Collateral Agent (with the
consent of the Required Lenders or, to the extent required by section 13.13 of
the Credit Agreement, all of the Lenders), PROVIDED, HOWEVER, that no such
change, waiver, modification or variance shall be made to this provision without
the consent of each Lender adversely affected thereby.

<PAGE>   33


         (j)      AGENCY PROVISIONS. By accepting the benefits of this
Instrument, each Lender acknowledges and agrees that the rights and obligations
of the Collateral Agent shall be as set forth in section 11 of the Credit
Agreement. Notwithstanding anything to the contrary contained in of this
Instrument, the duties and obligations of the Collateral Agent set forth or
incorporated into the provisions of this Instrument may not be amended or
modified without the consent of the Collateral Agent.

         (k)      WAIVER OF TRIAL BY JURY. THE BORROWER, COLLATERAL AGENT AND
TRUSTEE EACH HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS INSTRUMENT
OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         (l)      TIME OF ESSENCE. It is specifically agreed that time is of the
essence with respect to this Instrument and that the waiver of the rights or
options, or obligations secured hereby, shall not at any time thereafter be held
to be abandonment of such rights. Notice of the exercise of any right or option
granted to the Collateral Agent herein, or in the Indebtedness secured hereby,
is not required to be given.

         (m)      COUNTERPARTS. This Instrument may be executed by the Borrower
in counterparts, each of which shall be an original and all of which
collectively shall constitute one and the same instrument.

                             PROJECT PROMISSORY NOTE

$2,825,000                                                      October 13, 1999

         FOR VALUE RECEIVED, the undersigned ALS NATIONAL, INC., a Delaware
corporation (herein, together with its successors and assigns, the "COMPANY"),
hereby promises to pay to the order of Key Corporate Capital Inc. (the
"ADMINISTRATIVE AGENT"), as agent for the benefit of the Lenders (as defined in
the Credit Agreement referred to below (the "LENDER"), in lawful money of the
United States of America in immediately available funds, at the Payment Office
(such term and certain other capitalized terms used herein without definition
shall have the respective meanings ascribed thereto in the Credit Agreement
referred to below) of Key Corporate Capital Inc.(the "ADMINISTRATIVE AGENT"),
the principal sum of TWO MILLION EIGHT HUNDRED TWENTY FIVE THOUSAND DOLLARS
($2,825,000) or, if less, the then unpaid principal amount of all Loans made by
the Lender to the Borrowers pursuant to the Credit Agreement.

         The Company promises to pay the principal amount of each Loan made by
the Lender to each Borrower on the date the such Loan matures as provided in
section 2.7 of the Credit Agreement. The Company promises also to pay interest
on the unpaid principal amount of each Loan made by the Lender to each Borrower
in like money at said office from the date hereof until paid at the rates and at
the times provided in section 2.9 of the Credit Agreement.

         The Company is a co-maker of this Note and has guaranteed this Note as
provided in the Credit Agreement. As provided in the Joinder Supplement to which
any Borrower is a party, such Borrower has unconditionally assumed and agreed to
pay the principal of and interest on all Loans made to such Borrower by the
Lender which are evidenced hereby. Any payments of principal or interest on the
Loans made to a Borrower which are actually paid by such Borrower to the
Administrative Agent and distributed by the Administrative Agent to the Lender
shall be applied against the obligations of the Company hereunder in respect of
the principal of and interest on the Loans made to such Borrower.

         This Note is one of the Notes referred to in the Credit Agreement,
dated as of October 6, 1998, among the Company, the Borrowers from time to time

payable in the manner and with the effect provided in the Credit Agreement.

         The Company hereby waives presentment, demand, protest or notice of any
kind in connection with this Note.

         THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED WITH THE LAW OF THE STATE

         2.     UNIFORM COMMERCIAL CODE SECURITY AGREEMENT. This Instrument is
also a security agreement under the Uniform Commercial Code for any of the
Mortgaged Property which, under applicable law, may be subject to a security
interest under the Uniform Commercial Code, whether acquired now or in the
future, and all products and cash and non-cash proceeds thereof (collectively,
"UCC COLLATERAL"), and Borrower hereby grants to Lender a security interest in
the UCC Collateral. Borrower shall execute and deliver to Lender, upon Lender's
request, financing statements, continuation statements and amendments, in such
form as Lender may require to perfect or continue the perfection of this
security interest. Borrower shall pay all filing costs and all costs and
expenses of any record searches for financing statements that Lender may
require. Without the prior written consent of Lender, Borrower shall not create
or permit to exist any other lien or security interest in any of the UCC
Collateral. If an Event of Default has occurred and is continuing, Lender shall
have the remedies of a secured party under the Uniform Commercial Code, in
addition to all remedies provided by this Instrument or existing under
applicable law. In exercising any remedies, Lender may exercise its remedies
against the UCC Collateral separately or together, and in any order, without in
any way affecting the availability of Lender's other remedies. This Instrument
constitutes a financing statement with respect to any part of the Mortgaged
Property which is or may become a Fixture.

         3.     ASSIGNMENT OF RENTS; APPOINTMENT OF RECEIVER; LENDER IN
POSSESSION.

         (a)    As part of the consideration for the Indebtedness, Borrower
absolutely and unconditionally assigns and transfers to Lender all Rents. It is
the intention of Borrower to establish a present, absolute and irrevocable
transfer and assignment to Lender of all Rents and to authorize and empower
Lender to collect and receive all Rents without the necessity of further action
on the part of Borrower. Promptly upon request by Lender, Borrower agrees to
execute and deliver such further assignments as Lender may from time to time
require. Borrower and Lender intend this assignment of Rents to be immediately
effective and to constitute an absolute present assignment and not an assignment
for additional security only. For purposes of giving effect to this absolute
assignment of Rents, and for no other purpose, Rents shall not be deemed to be a
part of the "Mortgaged Property," as that term is defined in Section 1(s).
However, if this present, absolute and unconditional assignment of Rents is not
enforceable by its terms under the laws of the Property Jurisdiction, then the
Rents shall be included as a part of the Mortgaged Property and it is the
intention of the Borrower that in this circumstance this Instrument create and
perfect a lien on Rents in favor of Lender, which lien shall be effective as of
the date of this Instrument.

         (b)    After the occurrence of an Event of Default, Borrower authorizes
Lender to collect, sue for and compromise Rents and directs each tenant of the
Mortgaged Property to pay all Rents to, or as directed by, Lender. However,
until the occurrence of an Event of Default, Lender hereby


















<PAGE>   13


grants to Borrower a revocable license to collect and receive all Rents, to hold
all Rents in trust for the benefit of Lender and to apply all Rents to pay the
installments of interest and principal then due and payable under the Note and
the other amounts then due and payable under the other Loan Documents, including
Imposition Deposits, and to pay the current costs and expenses of managing,
operating and maintaining the Mortgaged Property, including utilities, Taxes and
insurance premiums (to the extent not included in Imposition Deposits), tenant
improvements and other capital expenditures. So long as no Event of Default has
occurred and is continuing, the Rents remaining after application pursuant to
the preceding sentence may be retained by Borrower free and clear of, and
released from, Lender's rights with respect to Rents under this Instrument. From
and after the occurrence of an Event of Default, and without the necessity of
Lender entering upon and taking and maintaining control of the Mortgaged
Property directly, or by a receiver, Borrower's license to collect Rents shall
automatically terminate and Lender shall without notice be entitled to all Rents
as they become due and payable, including Rents then due and unpaid. Borrower
shall pay to Lender upon demand all Rents to which Lender is entitled. At any
time on or after the date of Lender's demand for Rents, Lender may give, and
Borrower hereby irrevocably authorizes Lender to give, notice to all tenants of
the Mortgaged Property instructing them to pay all Rents to Lender, no tenant
shall be obligated to inquire further as to the occurrence or continuance of an
Event of Default, and no tenant shall be obligated to pay to Borrower any
amounts which are actually paid to Lender in response to such a notice. Any such
notice by Lender shall be delivered to each tenant personally, by mail or by
delivering such demand to each rental unit. Borrower shall not interfere with
and shall cooperate with Lender's collection of such Rents.

         (c)    Borrower represents and warrants to Lender that Borrower has not
executed any prior assignment of Rents (other than an assignment of Rents
securing indebtedness that will be paid off and discharged with the proceeds of
the loan evidenced by the Note), that Borrower has not performed, and Borrower
covenants and agrees that it will not perform, any acts and has not executed,
and shall not execute, any instrument which would prevent Lender from exercising
its rights under this Section 3, and that at the time of execution of this
Instrument there has been no anticipation or prepayment of any Rents for more
than two months prior to the due dates of such Rents. Borrower shall not collect
or accept payment of any Rents more than two months prior to the due dates of
such Rents.

         (d)    If an Event of Default has occurred and is continuing, Lender
may, regardless of the adequacy of Lender's security or the solvency of Borrower
and even in the absence of waste, enter upon and take and maintain full control
of the Mortgaged Property in order to perform all acts that Lender in its
discretion determines to be necessary or desirable for the operation and
maintenance of the Mortgaged Property, including the execution, cancellation or
modification of Leases, the collection of all Rents, the making of repairs to
the Mortgaged Property and the execution or termination of contracts providing
for the management, operation or maintenance of the Mortgaged Property, for the
purposes of enforcing the assignment of Rents pursuant to Section 3(a),
protecting




















<PAGE>   14


the Mortgaged Property or the security of this Instrument, or for such other
purposes as Lender in its discretion may deem necessary or desirable.
Alternatively, if an Event of Default has occurred and is continuing, regardless
of the adequacy of Lender's security, without regard to Borrower's solvency and
without the necessity of giving prior notice (oral or written) to Borrower,
Lender may apply to any court having jurisdiction for the appointment of a
receiver for the Mortgaged Property to take any or all of the actions set forth
in the preceding sentence. If Lender elects to seek the appointment of a
receiver for the Mortgaged Property at any time after an Event of Default has
occurred and is continuing, Borrower, by its execution of this Instrument,
expressly consents to the appointment of such receiver, including the
appointment of a receiver ex parte if permitted by applicable law. Lender or the
receiver, as the case may be, shall be entitled to receive a reasonable fee for
managing the Mortgaged Property. Immediately upon appointment of a receiver or
immediately upon the Lender's entering upon and taking possession and control of
the Mortgaged Property, Borrower shall surrender possession of the Mortgaged
Property to Lender or the receiver, as the case may be, and shall deliver to
Lender or the receiver, as the case may be, all documents, records (including
records on electronic or magnetic media), accounts, surveys, plans, and
specifications relating to the Mortgaged Property and all security deposits and
prepaid Rents. In the event Lender takes possession and control of the Mortgaged
Property, Lender may exclude Borrower and its representatives from the Mortgaged
Property. Borrower acknowledges and agrees that the exercise by Lender of any of
the rights conferred under this Section 3 shall not be construed to make Lender
a mortgagee-in-possession of the Mortgaged Property so long as Lender has not
itself entered into actual possession of the Land and Improvements.

         (e)    If Lender enters the Mortgaged Property, Lender shall be liable
to account only to Borrower and only for those Rents actually received. Lender
shall not be liable to Borrower, anyone claiming under or through Borrower or
anyone having an interest in the Mortgaged Property, by reason of any act or
omission of Lender under this Section 3, and Borrower hereby releases and
discharges Lender from any such liability to the fullest extent permitted by
law.

         (f)    If the Rents are not sufficient to meet the costs of taking
control of and managing the Mortgaged Property and collecting the Rents, any
funds expended by Lender for such purposes shall become an additional part of
the Indebtedness as provided in Section 12.

         (g)    Any entering upon and taking of control of the Mortgaged
Property by Lender or the receiver, as the case may be, and any application of
Rents as provided in this Instrument shall not cure or waive any Event of
Default or invalidate any other right or remedy of Lender under applicable law
or provided for in this Instrument.

         4.     ASSIGNMENT OF LEASES; LEASES AFFECTING THE MORTGAGED PROPERTY.



















<PAGE>   15


         (a)    As part of the consideration for the Indebtedness, Borrower
absolutely and unconditionally assigns and transfers to Lender all of Borrower's
right, title and interest in, to and under the Leases, including Borrower's
right, power and authority to modify the terms of any such Lease, or extend or
terminate any such Lease. It is the intention of Borrower to establish a
present, absolute and irrevocable transfer and assignment to Lender of all of
Borrower's right, title and interest in, to and under the Leases. Borrower and
Lender intend this assignment of the Leases to be immediately effective and to
constitute an absolute present assignment and not an assignment for additional
security only. For purposes of giving effect to this absolute assignment of the
Leases, and for no other purpose, the Leases shall not be deemed to be a part of
the "Mortgaged Property," as that term is defined in Section 1(s). However, if
this present, absolute and unconditional assignment of the Leases is not
enforceable by its terms under the laws of the Property Jurisdiction, then the
Leases shall be included as a part of the Mortgaged Property and it is the
intention of the Borrower that in this circumstance this Instrument create and
perfect a lien on the Leases in favor of Lender, which lien shall be effective
as of the date of this Instrument.

         (b)    Until Lender gives notice to Borrower of Lender's exercise of
its rights under this Section 4, Borrower shall have all rights, power and
authority granted to Borrower under any Lease (except as otherwise limited by
this Section or any other provision of this Instrument), including the right,
power and authority to modify the terms of any Lease or extend or terminate any
Lease. Upon the occurrence of an Event of Default, the permission given to
Borrower pursuant to the preceding sentence to exercise all rights, power and
authority under Leases shall automatically terminate. Borrower shall comply with
and observe Borrower's obligations under all Leases, including Borrower's
obligations pertaining to the maintenance and disposition of tenant security
deposits.

         (c)    Borrower acknowledges and agrees that the exercise by Lender,
either directly or by a receiver, of any of the rights conferred under this
Section 4 shall not be construed to make Lender a mortgagee-in-possession of the
Mortgaged Property so long as Lender has not itself entered into actual
possession of the Land and the Improvements. The acceptance by Lender of the
assignment of the Leases pursuant to Section 4(a) shall not at any time or in
any event obligate Lender to take any action under this Instrument or to expend
any money or to incur any expenses. Lender shall not be liable in any way for
any injury or damage to person or property sustained by any person or persons,
firm or corporation in or about the Mortgaged Property. Prior to Lender's actual
entry into and taking possession of the Mortgaged Property, Lender shall not (i)
be obligated to perform any of the terms, covenants and conditions contained in
any Lease (or otherwise have any obligation with respect to any Lease); (ii) be
obligated to appear in or defend any action or proceeding relating to the Lease
or the Mortgaged Property; or (iii) be responsible for the operation, control,
care, management or repair of the Mortgaged Property or any portion of the
Mortgaged Property. The execution of this Instrument by Borrower shall
constitute conclusive evidence that all responsibility


















<PAGE>   16


for the operation, control, care, management and repair of the Mortgaged
Property is and shall be that of Borrower, prior to such actual entry and taking
of possession.

         (d)   Upon delivery of notice by Lender to Borrower of Lender's
exercise of Lender's rights under this Section 4 at any time after the
occurrence of an Event of Default, and without the necessity of Lender entering
upon and taking and maintaining control of the Mortgaged Property directly, by a
receiver, or by any other manner or proceeding permitted by the laws of the
Property Jurisdiction, Lender immediately shall have all rights, powers and
authority granted to Borrower under any Lease, including the right, power and
authority to modify the terms of any such Lease, or extend or terminate any such
Lease.

         (e)    Borrower shall, promptly upon Lender's request, deliver to
Lender an executed copy of each residential Lease then in effect. All Leases for
residential dwelling units shall be on forms approved by Lender, shall be for
initial terms of at least six months and not more than two years, and shall not
include options to purchase. If customary in the applicable market, residential
Leases with terms of less than six months may be permitted with Lender's prior
written consent.

         (f)    Borrower shall not lease any portion of the Mortgaged Property
for non-residential use except with the prior written consent of Lender and
Lender's prior written approval of the Lease agreement. Borrower shall not
modify the terms of, or extend or terminate, any Lease for non-residential use
(including any Lease in existence on the date of this Instrument) without the
prior written consent of Lender. Borrower shall, without request by Lender,
deliver an executed copy of each non-residential Lease to Lender promptly after
such Lease is signed. All non-residential Leases, including renewals or
extensions of existing Leases, shall specifically provide that (1) such Leases
are subordinate to the lien of this Instrument (unless waived in writing by
Lender); (2) the tenant shall attorn to Lender and any purchaser at a
foreclosure sale, such attornment to be self-executing and effective upon
acquisition of title to the Mortgaged Property by any purchaser at a foreclosure
sale or by Lender in any manner; (3) the tenant agrees to execute such further
evidences of attornment as Lender or any purchaser at a foreclosure sale may
from time to time request; (4) the Lease shall not be terminated by foreclosure
or any other transfer of the Mortgaged Property; (5) after a foreclosure sale of
the Mortgaged Property, Lender or any other purchaser at such foreclosure sale
may, at Lender's or such purchaser's option, accept or terminate such Lease; and
(6) the tenant shall, upon receipt after the occurrence of an Event of Default
of a written request from Lender, pay all Rents payable under the Lease to
Lender.

         (g)    Borrower shall not receive or accept Rent under any Lease
(whether residential or non-residential) for more than two months in advance.

         5.     PAYMENT OF INDEBTEDNESS; PERFORMANCE UNDER LOAN DOCUMENTS;
PREPAYMENT PREMIUM. Borrower shall pay the Indebtedness when due


















<PAGE>   17


in accordance with the terms of the Note and the other Loan Documents and shall
perform, observe and comply with all other provisions of the Note and the other
Loan Documents. Borrower shall pay a prepayment premium in connection with
certain prepayments of the Indebtedness, including a payment made after Lender's
exercise of any right of acceleration of the Indebtedness, as provided in the
Note.

         6.     EXCULPATION. Borrower's personal liability for payment of the
Indebtedness and for performance of the other obligations to be performed by it
under this Instrument is limited in the manner, and to the extent, provided in
the Note.

         7.     DEPOSITS FOR TAXES, INSURANCE AND OTHER CHARGES.

         (a)    Borrower shall deposit with Lender on the day monthly
installments of principal or interest, or both, are due under the Note (or on
another day designated in writing by Lender), until the Indebtedness is paid in
full, an additional amount sufficient to accumulate with Lender the entire sum
required to pay, when due (1) any water and sewer charges which, if not paid,
may result in a lien on all or any part of the Mortgaged Property, (2) the
premiums for fire and other hazard insurance, rent loss insurance and such other
insurance as Lender may require under Section 19, (3) Taxes, and (4) amounts for
other charges and expenses which Lender at any time reasonably deems necessary
to protect the Mortgaged Property, to prevent the imposition of liens on the
Mortgaged Property, or otherwise to protect Lender's interests, all as
reasonably estimated from time to time by Lender. The amounts deposited under
the preceding sentence are collectively referred to in this Instrument as the
"IMPOSITION DEPOSITS". The obligations of Borrower for which the Imposition
Deposits are required are collectively referred to in this Instrument as
"IMPOSITIONS". The amount of the Imposition Deposits shall be sufficient to
enable Lender to pay each Imposition before the last date upon which such
payment may be made without any penalty or interest charge being added. Lender
shall maintain records indicating how much of the monthly Imposition Deposits
and how much of the aggregate Imposition Deposits held by Lender are held for
the purpose of paying Taxes, insurance premiums and each other obligation of
Borrower for which Imposition Deposits are required. Any waiver by Lender of the
requirement that Borrower remit Imposition Deposits to Lender may be revoked by
Lender, in Lender's discretion, at any time upon notice to Borrower.

         (b)    Imposition Deposits shall be held in an institution (which may
be Lender, if Lender is such an institution) whose deposits or accounts are
insured or guaranteed by a federal agency. Lender shall not be obligated to open
additional accounts or deposit Imposition Deposits in additional institutions
when the amount of the Imposition Deposits exceeds the maximum amount of the
federal deposit insurance or guaranty. Lender shall apply the Imposition
Deposits to pay Impositions so long as no Event of Default has occurred and is
continuing. Unless applicable law requires, Lender shall not be required to pay
Borrower any interest, earnings or profits on the Imposition Deposits. Borrower
hereby pledges and grants to Lender a security interest in the




















<PAGE>   18


Imposition Deposits as additional security for all of Borrower's obligations
under this Instrument and the other Loan Documents. Any amounts deposited with
Lender under this Section 7 shall not be trust funds, nor shall they operate to
reduce the Indebtedness, unless applied by Lender for that purpose under Section
7(e).

         (c)    If Lender receives a bill or invoice for an Imposition, Lender
shall pay the Imposition from the Imposition Deposits held by Lender. Lender
shall have no obligation to pay any Imposition to the extent it exceeds
Imposition Deposits then held by Lender. Lender may pay an Imposition according
to any bill, statement or estimate from the appropriate public office or
insurance company without inquiring into the accuracy of the bill, statement or
estimate or into the validity of the Imposition.

         (d)    If at any time the amount of the Imposition Deposits held by
Lender for payment of a specific Imposition exceeds the amount reasonably deemed
necessary by Lender, the excess shall be credited against future installments of
Imposition Deposits. If at any time the amount of the Imposition Deposits held
by Lender for payment of a specific Imposition is less than the amount
reasonably estimated by Lender to be necessary, Borrower shall pay to Lender the
amount of the deficiency within 15 days after notice from Lender.

         (e)    If an Event of Default has occurred and is continuing, Lender
may apply any Imposition Deposits, in any amounts and in any order as Lender
determines, in Lender's discretion, to pay any Impositions or as a credit
against the Indebtedness. Upon payment in full of the Indebtedness, Lender shall
refund to Borrower any Imposition Deposits held by Lender.

         8.     COLLATERAL AGREEMENTS. Borrower shall deposit with Lender such
amounts as may be required by any Collateral Agreement and shall perform all
other obligations of Borrower under each Collateral Agreement.

         9.     APPLICATION OF PAYMENTS. If at any time Lender receives, from
Borrower or otherwise, any amount applicable to the Indebtedness which is less
than all amounts due and payable at such time, then Lender may apply that
payment to amounts then due and payable in any manner and in any order
determined by Lender, in Lender's discretion. Neither Lender's acceptance of an
amount which is less than all amounts then due and payable nor Lender's
application of such payment in the manner authorized shall constitute or be
deemed to constitute either a waiver of the unpaid amounts or an accord and
satisfaction. Notwithstanding the application of any such amount to the
Indebtedness, Borrower's obligations under this Instrument and the Note shall
remain unchanged.

         10.    COMPLIANCE WITH LAWS. Borrower shall comply with all laws,
ordinances, regulations and requirements of any Governmental Authority and all
recorded lawful covenants and




















<PAGE>   19


agreements relating to or affecting the Mortgaged Property, including all laws,
ordinances, regulations, requirements and covenants pertaining to health and
safety, construction of improvements on the Mortgaged Property, fair housing,
zoning and land use, and Leases. Borrower also shall comply with all applicable
laws that pertain to the maintenance and disposition of tenant security
deposits. Borrower shall at all times maintain records sufficient to demonstrate
compliance with the provisions of this Section 10. Borrower shall take
appropriate measures to prevent, and shall not engage in or knowingly permit,
any illegal activities at the Mortgaged Property that could endanger tenants or
visitors, result in damage to the Mortgaged Property, result in forfeiture of
the Mortgaged Property, or otherwise materially impair the lien created by this
Instrument or Lender's interest in the Mortgaged Property. Borrower represents
and warrants to Lender that no portion of the Mortgaged Property has been or
will be purchased with the proceeds of any illegal activity.

         11.    USE OF PROPERTY. Unless required by applicable law, Borrower
shall not (a) except for any change in use approved by Lender, allow changes in
the use for which all or any part of the Mortgaged Property is being used at the
time this Instrument was executed, (b) convert any individual dwelling units or
common areas to commercial use, (c) initiate or acquiesce in a change in the
zoning classification of the Mortgaged Property, or (d) establish any
condominium or cooperative regime with respect to the Mortgaged Property.

         12.    PROTECTION OF LENDER'S SECURITY.

         (a)    If Borrower fails to perform any of its obligations under this
Instrument or any other Loan Document, or if any action or proceeding is
commenced which purports to affect the Mortgaged Property, Lender's security or
Lender's rights under this Instrument, including eminent domain, insolvency,
code enforcement, civil or criminal forfeiture, enforcement of Hazardous
Materials Laws, fraudulent conveyance or reorganizations or proceedings
involving a bankrupt or decedent, then Lender at Lender's option may make such
appearances, disburse such sums and take such actions as Lender reasonably deems
necessary to perform such obligations of Borrower and to protect Lender's
interest, including (1) payment of fees and out-of-pocket expenses of attorneys,
accountants, inspectors and consultants, (2) entry upon the Mortgaged Property
to make repairs or secure the Mortgaged Property, (3) procurement of the
insurance required by Section 19, and (4) payment of amounts which Borrower has
failed to pay under Sections 15 and 17.

         (b)    Any amounts disbursed by Lender under this Section 12, or under
any other provision of this Instrument that treats such disbursement as being
made under this Section 12, shall be added to, and become part of, the principal
component of the Indebtedness, shall be immediately due and payable and shall
bear interest from the date of disbursement until paid at the "DEFAULT RATE", as
defined in the Note.

<PAGE>   20


         (c)    Nothing in this Section 12 shall require Lender to incur any
expense or take any action.

         13.    INSPECTION. Lender, its agents, representatives, and designees
may make or cause to be made entries upon and inspections of the Mortgaged
Property (including environmental inspections and tests) during normal business
hours, or at any other reasonable time.

         14.    BOOKS AND RECORDS; FINANCIAL REPORTING.

         (a)    Borrower shall keep and maintain at all times at the Mortgaged
Property or the management agent's offices, and upon Lender's request shall make
available at the Mortgaged Property, complete and accurate books of account and
records (including copies of supporting bills and invoices) adequate to reflect
correctly the operation of the Mortgaged Property, and copies of all written
contracts, Leases, and other instruments which affect the Mortgaged Property.
The books, records, contracts, Leases and other instruments shall be subject to
examination and inspection at any reasonable time by Lender.

         (b)    Borrower shall furnish to Lender all of the following:

                (1)      within 120 days after the end of each fiscal year of
                         Borrower, a statement of income and expenses for
                         Borrower's operation of the Mortgaged Property for
                         that fiscal year, a statement of changes in financial
                         position of Borrower relating to the Mortgaged
                         Property for that fiscal year and, when requested by
                         Lender, a balance sheet showing all assets and
                         liabilities of Borrower relating to the Mortgaged
                         Property as of the end of that fiscal year;

                (2)      within 120 days after the end of each fiscal year of
                         Borrower, and at any other time upon Lender's
                         request, a rent schedule for the Mortgaged Property
                         showing the name of each tenant, and for each tenant,
                         the space occupied, the lease expiration date, the
                         rent payable for the current month, the date through
                         which rent has been paid, and any related information
                         requested by Lender;

                (3)      within 120 days after the end of each fiscal year of
                         Borrower, and at any other time upon Lender's
                         request, an accounting of all security deposits held
                         pursuant to all Leases, including the name of the
                         institution (if any) and the names and identification
                         numbers of the accounts (if any) in which such
                         security deposits are held and the name of the person
                         to contact at such financial institution, along with
                         any authority or release necessary for Lender to
                         access information regarding such accounts;















<PAGE>   21


                (4)      within 120 days after the end of each fiscal year of
                         Borrower, and at any other time upon Lender's
                         request, a statement that identifies all owners of
                         any interest in Borrower and the interest held by
                         each, if Borrower is a corporation, all officers and
                         directors of Borrower, and if Borrower is a limited
                         liability company, all managers who are not members;

                (5)      upon Lender's request, a monthly property management
                         report for the Mortgaged Property, showing the number
                         of inquiries made and rental applications received
                         from tenants or prospective tenants and deposits
                         received from tenants and any other information
                         requested by Lender;

                (6)      upon Lender's request, a balance sheet, a statement
                         of income and expenses for Borrower and a statement
                         of changes in financial position of Borrower for
                         Borrower's most recent fiscal year; and

                (7)      if required by Lender, a statement of income and
                         expense for the Mortgaged Property for the prior
                         month or quarter.

         (c)    Each of the statements, schedules and reports required by
Section 14(b) shall be certified to be complete and accurate by an individual
having authority to bind Borrower, and shall be in such form and contain such
detail as Lender may reasonably require. Lender also may require that any
statements, schedules or reports be audited at Borrower's expense by independent
certified public accountants acceptable to Lender.

         (d)    If Borrower fails to provide in a timely manner the statements,
schedules and reports required by Section 14(b), Lender shall have the right to
have Borrower's books and records audited, at Borrower's expense, by independent
certified public accountants selected by Lender in order to obtain such
statements, schedules and reports, and all related costs and expenses of Lender
shall become immediately due and payable and shall become an additional part of
the Indebtedness as provided in Section 12.

         (e)    If an Event of Default has occurred and is continuing, Borrower
shall deliver to Lender upon written demand all books and records relating to
the Mortgaged Property or its operation.

         (f)    Borrower authorizes Lender to obtain a credit report on Borrower
at any time.

         (g)    If an Event of Default has occurred and Lender has not
previously required Borrower to furnish a quarterly statement of income and
expense for the Mortgaged Property,























<PAGE>   22


Lender may require Borrower to furnish such a statement within 45 days after the
end of each fiscal quarter of Borrower following such Event of Default.

         15.    TAXES; OPERATING EXPENSES.

         (a)    Subject to the provisions of Section 15(c) and Section 15(d),
Borrower shall pay, or cause to be paid, all Taxes when due and before the
addition of any interest, fine, penalty or cost for nonpayment.

         (b)    Subject to the provisions of Section 15(c), Borrower shall pay
the expenses of operating, managing, maintaining and repairing the Mortgaged
Property (including insurance premiums, utilities, repairs and replacements)
before the last date upon which each such payment may be made without any
penalty or interest charge being added.

         (c)    As long as no Event of Default exists and Borrower has timely
delivered to Lender any bills or premium notices that it has received, Borrower
shall not be obligated to pay Taxes, insurance premiums or any other individual
Imposition to the extent that sufficient Imposition Deposits are held by Lender
for the purpose of paying that specific Imposition. If an Event of Default
exists, Lender may exercise any rights Lender may have with respect to
Imposition Deposits without regard to whether Impositions are then due and
payable. Lender shall have no liability to Borrower for failing to pay any
Impositions to the extent that any Event of Default has occurred and is
continuing, insufficient Imposition Deposits are held by Lender at the time an
Imposition becomes due and payable or Borrower has failed to provide Lender with
bills and premium notices as provided above.

         (d)    Borrower, at its own expense, may contest by appropriate legal
proceedings, conducted diligently and in good faith, the amount or validity of
any Imposition other than insurance premiums, if (1) Borrower notifies Lender of
the commencement or expected commencement of such proceedings, (2) the Mortgaged
Property is not in danger of being sold or forfeited, (3) Borrower deposits with
Lender reserves sufficient to pay the contested Imposition, if requested by
Lender, and (4) Borrower furnishes whatever additional security is required in
the proceedings or is reasonably requested by Lender, which may include the
delivery to Lender of the reserves established by Borrower to pay the contested
Imposition.

         (e)    Borrower shall promptly deliver to Lender a copy of all notices
of, and invoices for, Impositions, and if Borrower pays any Imposition directly,
Borrower shall promptly furnish to Lender receipts evidencing such payments.

         16.    LIENS; ENCUMBRANCES. Borrower acknowledges that, to the extent
provided in Section 21, the grant, creation or existence of any mortgage, deed
of trust, deed to secure debt,























<PAGE>   23


security interest or other lien or encumbrance (a "LIEN") on the Mortgaged
Property (other than the lien of this Instrument) or on certain ownership
interests in Borrower, whether voluntary, involuntary or by operation of law,
and whether or not such Lien has priority over the lien of this Instrument, is a
"TRANSFER" which constitutes an Event of Default.

         17.    PRESERVATION, MANAGEMENT AND MAINTENANCE OF MORTGAGED PROPERTY.

         (a)    Borrower (1) shall not commit waste or permit impairment or
deterioration of the Mortgaged Property, (2) shall not abandon the Mortgaged
Property, (3) shall restore or repair promptly, in a good and workmanlike
manner, any damaged part of the Mortgaged Property to the equivalent of its
original condition, or such other condition as Lender may approve in writing,
whether or not insurance proceeds or condemnation awards are available to cover
any costs of such restoration or repair, (4) shall keep the Mortgaged Property
in good repair, including the replacement of Personalty and Fixtures with items
of equal or better function and quality, (5) shall provide for professional
management of the Mortgaged Property by a residential rental property manager
satisfactory to Lender under a contract approved by Lender in writing, and (6)
shall give notice to Lender of and, unless otherwise directed in writing by
Lender, shall appear in and defend any action or proceeding purporting to affect
the Mortgaged Property, Lender's security or Lender's rights under this
Instrument. Borrower shall not (and shall not permit any tenant or other person
to) remove, demolish or alter the Mortgaged Property or any part of the
Mortgaged Property except in connection with the replacement of tangible
Personalty.

         (b)    If, in connection with the making of the loan evidenced by the
Note or at any later date, Lender waives in writing the requirement of Section
17(a)(5) above that Borrower enter into a written contract for management of the
Mortgaged Property and if, after the date of this Instrument, Borrower intends
to change the management of the Mortgaged Property, Lender shall have the right
to approve such new property manager and the written contract for the management
of the Mortgaged Property and require that Borrower and such new property
manager enter into an Assignment of Management Agreement on a form approved by
Lender. If required by Lender (whether before or after an Event of Default),
Borrower will cause any Affiliate of Borrower to whom fees are payable for the
management of the Mortgaged Property to enter into an agreement with Lender, in
a form approved by Lender, providing for subordination of those fees and such
other provisions as Lender may require. "Affiliate of Borrower" means any
corporation, partnership, joint venture, limited liability company, limited
liability partnership, trust or individual controlled by, under common control
with, or which controls Borrower (the term "control" for these purposes shall
mean the ability, whether by the ownership of shares or other equity interests,
by contract or otherwise, to elect a majority of the directors of a corporation,
to make management decisions on behalf of, or independently to select the
managing partner of, a partnership, or otherwise to have the power independently
to remove and then select a majority of those

<PAGE>   24


individuals exercising managerial authority over an entity, and control shall be
conclusively presumed in the case of the ownership of 50% or more of the equity
interests).

         18.    ENVIRONMENTAL HAZARDS.

         (a)    Except for matters covered by a written program of operations
and maintenance approved in writing by Lender (an "O&M PROGRAM") or matters
described in Section 18(b), Borrower shall not cause or permit any of the
following:

                (1)      the presence, use, generation, release, treatment,
                         processing, storage (including storage in above
                         ground and underground storage tanks), handling, or
                         disposal of any Hazardous Materials on or under the
                         Mortgaged Property or any other property of Borrower
                         that is adjacent to the Mortgaged Property;

                (2)      the transportation of any Hazardous Materials to, from,
                         or across the Mortgaged Property;

                (3)      any occurrence or condition on the Mortgaged Property
                         or any other property of Borrower that is adjacent to
                         the Mortgaged Property, which occurrence or condition
                         is or may be in violation of Hazardous Materials
                         Laws; or

                (4)      any violation of or noncompliance with the terms of
                         any Environmental Permit with respect to the
                         Mortgaged Property or any property of Borrower that
                         is adjacent to the Mortgaged Property.

The matters  described  in clauses  (1) through (4) above are referred to
collectively in this Section 18 as "PROHIBITED ACTIVITIES OR CONDITIONS".

         (b)    Prohibited Activities and Conditions shall not include the safe
and lawful use and storage of quantities of (1) pre-packaged supplies, cleaning
materials and petroleum products customarily used in the operation and
maintenance of comparable multifamily properties, (2) cleaning materials,
personal grooming items and other items sold in pre-packaged containers for
consumer use and used by tenants and occupants of residential dwelling units in
the Mortgaged Property; and (3) petroleum products used in the operation and
maintenance of motor vehicles from time to time located on the Mortgaged
Property's parking areas, so long as all of the foregoing are used, stored,
handled, transported and disposed of in compliance with Hazardous Materials
Laws.




<PAGE>   25


         (c)    Borrower shall take all commercially reasonable actions
(including the inclusion of appropriate provisions in any Leases executed after
the date of this Instrument) to prevent its employees, agents, and contractors,
and all tenants and other occupants from causing or permitting any Prohibited
Activities or Conditions. Borrower shall not lease or allow the sublease or use
of all or any portion of the Mortgaged Property to any tenant or subtenant for
nonresidential use by any user that, in the ordinary course of its business,
would cause or permit any Prohibited Activity or Condition.

         (d)    If an O&M Program has been established with respect to Hazardous
Materials, Borrower shall comply in a timely manner with, and cause all
employees, agents, and contractors of Borrower and any other persons present on
the Mortgaged Property to comply with the O&M Program. All costs of performance
of Borrower's obligations under any O&M Program shall be paid by Borrower, and
Lender's out-of-pocket costs incurred in connection with the monitoring and
review of the O&M Program and Borrower's performance shall be paid by Borrower
upon demand by Lender. Any such out-of-pocket costs of Lender which Borrower
fails to pay promptly shall become an additional part of the Indebtedness as
provided in Section 12.

         (e)    Borrower represents and warrants to Lender that, except as
previously disclosed by Borrower to Lender in writing:

                (1)      Borrower has not at any time engaged in, caused or
                         permitted any  Prohibited  Activities or Conditions;

                (2)      to the best of Borrower's knowledge after reasonable
                         and diligent inquiry, no Prohibited Activities or
                         Conditions exist or have existed;

                (3)      except to the extent previously disclosed by Borrower
                         to Lender in writing, the Mortgaged Property does not
                         now contain any underground storage tanks, and, to
                         the best of Borrower's knowledge after reasonable and
                         diligent inquiry, the Mortgaged Property has not
                         contained any underground storage tanks in the past.
                         If there is an underground storage tank located on
                         the Property which has been previously disclosed by
                         Borrower to Lender in writing, that tank complies
                         with all requirements of Hazardous Materials Laws;

                (4)      Borrower has complied with all Hazardous Materials
                         Laws, including all requirements for notification
                         regarding releases of Hazardous Materials. Without
                         limiting the generality of the foregoing, Borrower
                         has obtained all Environmental Permits required for
                         the operation of the Mortgaged Property




<PAGE>   26


                         in accordance with Hazardous Materials Laws now in
                         effect and all such Environmental Permits are in full
                         force and effect;

                (5)      no event has occurred with respect to the Mortgaged
                         Property that constitutes, or with the passing of
                         time or the giving of notice would constitute,
                         noncompliance with the terms of any Environmental
                         Permit;

                (6)      there are no actions, suits, claims or proceedings
                         pending or, to the best of Borrower's knowledge after
                         reasonable and diligent inquiry, threatened that
                         involve the Mortgaged Property and allege, arise out
                         of, or relate to any Prohibited Activity or
                         Condition; and

                (7)      Borrower has not received any complaint, order,
                         notice of violation or other communication from any
                         Governmental Authority with regard to air emissions,
                         water discharges, noise emissions or Hazardous
                         Materials, or any other environmental, health or
                         safety matters affecting the Mortgaged Property or
                         any other property of Borrower that is adjacent to
                         the Mortgaged Property.

The representations and warranties in this Section 18 shall be continuing
representations and warranties that shall be deemed to be made by Borrower
throughout the term of the loan evidenced by the Note, until the Indebtedness
has been paid in full.

         (f)    Borrower shall promptly notify Lender in writing upon the
occurrence of any of the following events:

                (1)      Borrower's discovery of any Prohibited Activity or
                         Condition;

                (2)      Borrower's receipt of or knowledge of any complaint,
                         order, notice of violation or other communication
                         from any Governmental Authority or other person with
                         regard to present or future alleged Prohibited
                         Activities or Conditions or any other environmental,
                         health or safety matters affecting the Mortgaged
                         Property or any other property of Borrower that is
                         adjacent to the Mortgaged Property; and

                (3)      any  representation  or warranty in this  Section 18
                         becomes  untrue  after the date of this Agreement.

Any such notice given by Borrower shall not relieve Borrower of, or result in a
waiver of, any obligation under this Instrument, the Note, or any other Loan
Document.




<PAGE>   27


         (g)    Borrower shall pay promptly the costs of any environmental
inspections, tests or audits ("ENVIRONMENTAL INSPECTIONS") required by Lender in
connection with any foreclosure or deed in lieu of foreclosure, or as a
condition of Lender's consent to any Transfer under Section 21, or required by
Lender following a reasonable determination by Lender that Prohibited Activities
or Conditions may exist. Any such costs incurred by Lender (including the fees
and out-of-pocket costs of attorneys and technical consultants whether incurred
in connection with any judicial or administrative process or otherwise) which
Borrower fails to pay promptly shall become an additional part of the
Indebtedness as provided in Section 12. The results of all Environmental
Inspections made by Lender shall at all times remain the property of Lender and
Lender shall have no obligation to disclose or otherwise make available to
Borrower or any other party such results or any other information obtained by
Lender in connection with its Environmental Inspections. Lender hereby reserves
the right, and Borrower hereby expressly authorizes Lender, to make available to
any party, including any prospective bidder at a foreclosure sale of the
Mortgaged Property, the results of any Environmental Inspections made by Lender
with respect to the Mortgaged Property. Borrower consents to Lender notifying
any party (either as part of a notice of sale or otherwise) of the results of
any of Lender's Environmental Inspections. Borrower acknowledges that Lender
cannot control or otherwise assure the truthfulness or accuracy of the results
of any of its Environmental Inspections and that the release of such results to
prospective bidders at a foreclosure sale of the Mortgaged Property may have a
material and adverse effect upon the amount which a party may bid at such sale.
Borrower agrees that Lender shall have no liability whatsoever as a result of
delivering the results of any of its Environmental Inspections to any third
party, and Borrower hereby releases and forever discharges Lender from any and
all claims, damages, or causes of action, arising out of, connected with or
incidental to the results of, the delivery of any of Lender's Environmental
Inspections.

         (h)    If any investigation, site monitoring, containment, clean-up,
restoration or other remedial work ("REMEDIAL WORK") is necessary to comply with
any Hazardous Materials Law or order of any Governmental Authority that has or
acquires jurisdiction over the Mortgaged Property or the use, operation or
improvement of the Mortgaged Property under any Hazardous Materials Law,
Borrower shall, by the earlier of (1) the applicable deadline required by
Hazardous Materials Law or (2) 30 days after notice from Lender demanding such
action, begin performing the Remedial Work, and thereafter diligently prosecute
it to completion, and shall in any event complete the work by the time required
by applicable Hazardous Materials Law. If Borrower fails to begin on a timely
basis or diligently prosecute any required Remedial Work, Lender may, at its
option, cause the Remedial Work to be completed, in which case Borrower shall
reimburse Lender on demand for the cost of doing so. Any reimbursement due from
Borrower to Lender shall become part of the Indebtedness as provided in Section
12.




<PAGE>   28


         (i)    Borrower shall cooperate with any inquiry by any Governmental
Authority and shall comply with any governmental or judicial order which arises
from any alleged Prohibited Activity or Condition.

         (j)    Borrower shall indemnify, hold harmless and defend (i) Lender,
(ii) any prior owner or holder of the Note, (iii) the Loan Servicer, (iv) any
prior Loan Servicer, (v) the officers, directors, shareholders, partners,
employees and trustees of any of the foregoing, and (vi) the heirs, legal
representatives, successors and assigns of each of the foregoing (collectively,
the "INDEMNITEES") from and against all proceedings, claims, damages, penalties
and costs (whether initiated or sought by Governmental Authorities or private
parties), including fees and out-of-pocket expenses of attorneys and expert
witnesses, investigatory fees, and remediation costs, whether incurred in
connection with any judicial or administrative process or otherwise, arising
directly or indirectly from any of the following:

                (1)      any breach of any representation or warranty of
                         Borrower in this Section 18;

                (2)      any failure by Borrower to perform any of its
                         obligations under this Section 18;

                (3)      the existence or alleged existence of any Prohibited
                         Activity or Condition;

                (4)      the presence or alleged presence of Hazardous
                         Materials on or under the Mortgaged Property or any
                         property of Borrower that is adjacent to the
                         Mortgaged Property; and

                (5)      the actual or alleged violation of any Hazardous
                         Materials Law.

         (k)    Counsel selected by Borrower to defend Indemnitees shall be
subject to the approval of those Indemnitees. However, any Indemnitee may elect
to defend any claim or legal or administrative proceeding at the Borrower's
expense.

         (l)    Borrower shall not, without the prior written consent of those
Indemnitees who are named as parties to a claim or legal or administrative
proceeding (a "CLAIM"), settle or compromise the Claim if the settlement (1)
results in the entry of any judgment that does not include as an unconditional
term the delivery by the claimant or plaintiff to Lender of a written release of
those Indemnitees, satisfactory in form and substance to Lender; or (2) may
materially and adversely affect Lender, as determined by Lender in its
discretion.




<PAGE>   29


         (m)    Lender agrees that the indemnity under this Section 18 shall be
limited to the assets of Borrower and Lender shall not seek to recover any
deficiency from any natural persons who are general partners of Borrower.

         (n)    Borrower shall, at its own cost and expense, do all of the
following:

                (1)      pay or satisfy any judgment or decree that may be
                         entered against any Indemnitee or Indemnitees in any
                         legal or administrative proceeding incident to any
                         matters against which Indemnitees are entitled to be
                         indemnified under this Section 18;

                (2)      reimburse Indemnitees for any expenses paid or
                         incurred in connection with any matters against which
                         Indemnitees are entitled to be indemnified under this
                         Section 18; and

                (3)      reimburse Indemnitees for any and all expenses,
                         including fees and out-of-pocket expenses of
                         attorneys and expert witnesses, paid or incurred in
                         connection with the enforcement by Indemnitees of
                         their rights under this Section 18, or in monitoring
                         and participating in any legal or administrative
                         proceeding.

         (o)    In any circumstances in which the indemnity under this Section
18 applies, Lender may employ its own legal counsel and consultants to
prosecute, defend or negotiate any claim or legal or administrative proceeding
and Lender, with the prior written consent of Borrower (which shall not be
unreasonably withheld, delayed or conditioned), may settle or compromise any
action or legal or administrative proceeding. Borrower shall reimburse Lender
upon demand for all costs and expenses incurred by Lender, including all costs
of settlements entered into in good faith, and the fees and out-of-pocket
expenses of such attorneys and consultants.

         (p)    The provisions of this Section 18 shall be in addition to any
and all other obligations and liabilities that Borrower may have under
applicable law or under other Loan Documents, and each Indemnitee shall be
entitled to indemnification under this Section 18 without regard to whether
Lender or that Indemnitee has exercised any rights against the Mortgaged
Property or any other security, pursued any rights against any guarantor, or
pursued any other rights available under the Loan Documents or applicable law.
If Borrower consists of more than one person or entity, the obligation of those
persons or entities to indemnify the Indemnitees under this Section 18 shall be
joint and several. The obligation of Borrower to indemnify the Indemnitees under
this Section 18 shall survive any repayment or discharge of the Indebtedness,
any foreclosure proceeding, any foreclosure sale, any delivery of any deed in
lieu of foreclosure, and any release of record of the lien of this Instrument.

         19.    PROPERTY AND LIABILITY INSURANCE.

         (a)    Borrower shall keep the Improvements insured at all times
against such hazards as Lender may from time to time require, which insurance
shall include but not be limited to coverage against loss by fire and allied
perils, general boiler and machinery coverage, and business income coverage.
Lender's insurance requirements may change from time to time throughout the term
of the Indebtedness. If Lender so requires, such insurance shall also include
sinkhole insurance, mine subsidence insurance, earthquake insurance, and, if the
Mortgaged Property does not conform to applicable zoning or land use laws,
building ordinance or law coverage. If any of the Improvements is located in an
area identified by the Federal Emergency Management Agency (or any successor to
that agency) as an area having special flood hazards, and if flood insurance is
available in that area, Borrower shall insure such Improvements against loss by
flood.

         (b)    All premiums on insurance policies required under Section 19(a)
shall be paid in the manner provided in Section 7, unless Lender has designated
in writing another method of payment. All such policies shall also be in a form
approved by Lender. All policies of property damage insurance shall include a
non-contributing, non-reporting mortgage clause in favor of, and in a form
approved by, Lender. Lender shall have the right to hold the original policies
or duplicate original policies of all insurance required by Section 19(a).
Borrower shall promptly deliver to Lender a copy of all renewal and other
notices received by Borrower with respect to the policies and all receipts for
paid premiums. At least 30 days prior to the expiration date of a policy,
Borrower shall deliver to Lender the original (or a duplicate original) of a
renewal policy in form satisfactory to Lender.

         (c)    Borrower shall maintain at all times commercial general
liability insurance, workers' compensation insurance and such other liability,
errors and omissions and fidelity insurance coverages as Lender may from time to
time require.

         (d)    All insurance policies and renewals of insurance policies
required by this Section 19 shall be in such amounts and for such periods as
Lender may from time to time require, and shall be issued by insurance companies
satisfactory to Lender.

         (e)    Borrower shall comply with all insurance requirements and shall
not permit any condition to exist on the Mortgaged Property that would
invalidate any part of any insurance coverage that this Instrument requires
Borrower to maintain.

         (f)    In the event of loss, Borrower shall give immediate written
notice to the insurance carrier and to Lender. Borrower hereby authorizes and
appoints Lender as attorney-in-fact for Borrower to make proof of loss, to
adjust and compromise any claims under policies of property

damage insurance, to appear in and prosecute any action arising from such
property damage insurance policies, to collect and receive the proceeds of
property damage insurance, and to deduct from such proceeds Lender's expenses
incurred in the collection of such proceeds. This power of attorney is coupled
with an interest and therefore is irrevocable. However, nothing contained in
this Section 19 shall require Lender to incur any expense or take any action.
Lender may, at Lender's option, (1) hold the balance of such proceeds to be used
to reimburse Borrower for the cost of restoring and repairing the Mortgaged
Property to the equivalent of its original condition or to a condition approved
by Lender (the "RESTORATION"), or (2) apply the balance of such proceeds to the
payment of the Indebtedness, whether or not then due. To the extent Lender
determines to apply insurance proceeds to Restoration, Lender shall do so in
accordance with Lender's then-current policies relating to the restoration of
casualty damage on similar multifamily properties.

         (g)    Lender shall not exercise its option to apply insurance proceeds
to the payment of the Indebtedness if all of the following conditions are met:
(1) no Event of Default (or any event which, with the giving of notice or the
passage of time, or both, would constitute an Event of Default) has occurred and
is continuing; (2) Lender determines, in its discretion, that there will be
sufficient funds to complete the Restoration; (3) Lender determines, in its
discretion, that the rental income from the Mortgaged Property after completion
of the Restoration will be sufficient to meet all operating costs and other
expenses, Imposition Deposits, deposits to reserves and loan repayment
obligations relating to the Mortgaged Property; (4) Lender determines, in its
discretion, that the Restoration will be completed before the earlier of (A) one
year before the maturity date of the Note or (B) one year after the date of the
loss or casualty; and (5) upon Lender's request, Borrower provides Lender
evidence of the availability during and after the Restoration of the insurance
required to be maintained by Borrower pursuant to this Section 19.

         (h)    If the Mortgaged Property is sold at a foreclosure sale or
Lender acquires title to the Mortgaged Property, Lender shall automatically
succeed to all rights of Borrower in and to any insurance policies and unearned
insurance premiums and in and to the proceeds resulting from any damage to the
Mortgaged Property prior to such sale or acquisition.

         20.    CONDEMNATION.

         (a)    Borrower shall promptly notify Lender of any action or
proceeding relating to any condemnation or other taking, or conveyance in lieu
thereof, of all or any part of the Mortgaged Property, whether direct or
indirect (a "CONDEMNATION"). Borrower shall appear in and prosecute or defend
any action or proceeding relating to any Condemnation unless otherwise directed
by Lender in writing. Borrower authorizes and appoints Lender as
attorney-in-fact for Borrower to commence, appear in and prosecute, in Lender's
or Borrower's name, any action or proceeding relating to any Condemnation and to
settle or compromise any claim in connection with any Condemnation. This power
of attorney is coupled with an interest and therefore is irrevocable.




<PAGE>   32


However, nothing contained in this Section 20 shall require Lender to incur any
expense or take any action. Borrower hereby transfers and assigns to Lender all
right, title and interest of Borrower in and to any award or payment with
respect to (i) any Condemnation, or any conveyance in lieu of Condemnation, and
(ii) any damage to the Mortgaged Property caused by governmental action that
does not result in a Condemnation.

         (b)    Lender may apply such awards or proceeds, after the deduction of
Lender's expenses incurred in the collection of such amounts, at Lender's
option, to the restoration or repair of the Mortgaged Property or to the payment
of the Indebtedness, with the balance, if any, to Borrower. Unless Lender
otherwise agrees in writing, any application of any awards or proceeds to the
Indebtedness shall not extend or postpone the due date of any monthly
installments referred to in the Note, Section 7 of this Instrument or any
Collateral Agreement, or change the amount of such installments. Borrower agrees
to execute such further evidence of assignment of any awards or proceeds as
Lender may require.

         21.    TRANSFERS OF THE MORTGAGED PROPERTY OR INTERESTS IN BORROWER.

         (a)    The occurrence of any of the following events shall constitute
an Event of Default under this Instrument:

                (1)      a  Transfer of all or any part of the Mortgaged
                         Property or any interest in the Mortgaged Property;

                (2)      a Transfer of a Controlling Interest in Borrower;

                (3)      a Transfer of a Controlling Interest in any entity
                         which owns, directly or indirectly through one or
                         more intermediate entities, a Controlling Interest in
                         Borrower;

                (4)      a Transfer of all or any part of Key Principal's
                         ownership interests (other than limited partnership
                         interests) in Borrower, or in any other entity which
                         owns, directly or indirectly through one or more
                         intermediate entities, an ownership interest in
                         Borrower;

                (5)      if Key Principal is an entity, (A) a Transfer of a
                         Controlling Interest in Key Principal, or (B) a
                         Transfer of a Controlling Interest in any entity
                         which owns, directly or indirectly through one or
                         more intermediate entities, a Controlling Interest in
                         Key Principal;





<PAGE>   33


                (6)      if Borrower or Key Principal is a trust, the
                         termination or revocation of such trust; and

                (7)      a conversion of Borrower from one type of legal
                         entity into another type of legal entity, whether or
                         not there is a Transfer.

         Lender shall not be required to demonstrate any actual impairment of
its security or any increased risk of default in order to exercise any of its
remedies with respect to an Event of Default under this Section 21.

         (b)    The occurrence of any of the following events shall not
constitute an Event of Default under this Instrument, notwithstanding any
provision of Section 21(a) to the contrary:

                (1)      a Transfer to which Lender has consented;

                (2)      a Transfer that occurs by devise, descent, or by
                         operation of law upon the death of a natural person;

                (3)      the grant of a leasehold interest in an individual
                         dwelling unit for a term of two years or less not
                         containing an option to purchase;

                (4)      a Transfer of obsolete or worn out Personalty or
                         Fixtures that are contemporaneously replaced by items
                         of equal or better function and quality, which are
                         free of liens, encumbrances and security interests
                         other than those created by the Loan Documents or
                         consented to by Lender;

                (5)      the grant of an easement, if before the grant Lender
                         determines that the easement will not materially
                         affect the operation or value of the Mortgaged
                         Property or Lender's interest in the Mortgaged
                         Property, and Borrower pays to Lender, upon demand,
                         all costs and expenses incurred by Lender in
                         connection with reviewing Borrower's request; and

                (6)      the creation of a tax lien or a mechanic's,
                         materialman's or judgment lien against the Mortgaged
                         Property which is bonded off, released of record or
                         otherwise remedied to Lender's satisfaction within 30
                         days of the date of creation.

         (c)    Lender shall consent, without any adjustment to the rate at
which the Indebtedness secured by this Instrument bears interest or to any other
economic terms of the Indebtedness, to a




<PAGE>   34
Transfer that would otherwise violate this Section 21 if, prior to the Transfer,
Borrower has satisfied each of the following requirements:

                  (1)      the submission to Lender of all information required
                           by Lender to make the determination required by this
                           Section 21(c);

                  (2)      the absence of any Event of Default;

                  (3)      the transferee meets all of the eligibility, credit,
                           management and other standards (including any
                           standards with respect to previous relationships
                           between Lender and the transferee and the
                           organization of the transferee) customarily applied
                           by Lender at the time of the proposed Transfer to the
                           approval of borrowers in connection with the
                           origination or purchase of similar mortgages, deeds
                           of trust or deeds to secure debt on multifamily
                           properties;

                  (4)      the Mortgaged Property, at the time of the proposed
                           Transfer, meets all standards as to its physical
                           condition that are customarily applied by Lender at
                           the time of the proposed Transfer to the approval of
                           properties in connection with the origination or
                           purchase of similar mortgages on multifamily
                           properties;

                  (5)      in the case of a Transfer of all or any part of the
                           Mortgaged Property, or direct or indirect ownership
                           interests in Borrower or Key Principal (if an
                           entity), if transferor or any other person has
                           obligations under any Loan Document, the execution by
                           the transferee or one or more individuals or entities
                           acceptable to Lender of an assumption agreement
                           (including, if applicable, an Acknowledgement and
                           Agreement of Key Principal to Personal Liability for
                           Exceptions to Non-Recourse Liability) that is
                           acceptable to Lender and that, among other things,
                           requires the transferee to perform all obligations of
                           transferor or such person set forth in such Loan
                           Document, and may require that the transferee comply
                           with any provisions of this Instrument or any other
                           Loan Document which previously may have been waived
                           by Lender;

                  (6)      if a guaranty has been executed and delivered in
                           connection with the Note, this Instrument or any of
                           the other Loan Documents, the Borrower causes one or

                           acceptable to Lender; and

<PAGE>   35

                  (7)      Lender's receipt of all of the following:

                           (A)      a non-refundable  review fee in the amount
                                    of $3,000 and a transfer fee equal to 1
                                    percent of the outstanding  Indebtedness
                                    immediately prior to the Transfer.

                           (B)      In addition, Borrower shall be required to
                                    reimburse Lender for all of Lender's
                                    out-of-pocket costs (including reasonable
                                    attorneys' fees) incurred in reviewing the
                                    Transfer request, to the extent such
                                    expenses exceed $3,000.

         (d) For purposes of this Section, the following terms shall have the
meanings set forth below:

                  (1)      "INITIAL  OWNERS"  means,  with respect to Borrower
                           or any other entity,  the persons or entities who on
                           the date of the Note own in the aggregate 100% of the
                           ownership interests in Borrower or that entity.

                  (2)      A Transfer of a "CONTROLLING INTEREST" shall mean,
                           with respect to any entity, the following:

                           (i)      if such entity is a general partnership or a
                                    joint venture, a Transfer of any general
                                    partnership interest or joint venture
                                    interest which would cause the Initial
                                    Owners to own less than 51% of all general
                                    partnership or joint venture interests in
                                    such entity;

                                    interest;

                           (iii)    if such entity is a limited liability
                                    company or a limited liability partnership,
                                    a Transfer of any membership or other
                                    ownership interest which would cause the
                                    Initial Owners to own less than 51% of all
                                    membership or other ownership interests in
                                    such entity;

                           (iv)     if such entity is a corporation (other than
                                    a Publicly-Held Corporation) with only one
                                    class of voting stock, a Transfer of any
                                    voting stock which would cause the Initial
                                    Owners to own less than 51% of voting stock
                                    in such corporation;

<PAGE>   36


                           (v)      if such entity is a corporation (other than
                                    a Publicly-Held Corporation) with more than
                                    one class of voting stock, a Transfer of any
                                    voting stock which would cause the Initial
                                    Owners to own less than a sufficient number
                                    of shares of voting stock having the power
                                    to elect the majority of directors of such
                                    corporation; and

                           (vi)     if such entity is a trust, the removal,
                                    appointment or substitution of a trustee of
                                    such trust other than (A) in the case of a
                                    land trust, or (B) if the trustee of such
                                    trust after such removal, appointment or
                                    substitution is a trustee identified in the
                                    trust agreement approved by Lender.

                  (3)      "PUBLICLY-HELD  CORPORATION"  shall mean a
                           corporation  the outstanding  voting stock of which
                           is registered  under Section 12(b) or 12(g) of the
                           Securities and Exchange Act of 1934, as amended.

         22.      EVENTS OF DEFAULT.  The occurrence of any one or more of the
following shall constitute an Event of Default under this Instrument:

         (a)      any failure by Borrower to pay or deposit when due any amount
required by the Note, this Instrument or any other Loan Document;

         (b)      any failure by Borrower to maintain the insurance coverage
required by Section 19;

         (c)      any failure by Borrower to comply with the provisions of
Section 33;

         (d)      fraud or material misrepresentation or material omission by
Borrower, or any of its officers, directors, trustees, general partners or
managers, Key Principal or any guarantor in connection with (A) the application
for or creation of the Indebtedness, (B) any financial statement, rent roll, or
other report or information provided to Lender during the term of the
Indebtedness, or (C) any request for Lender's consent to any proposed action,
including a request for disbursement of funds under any Collateral Agreement;

         (e)      any Event of Default under Section 21;

         (f)      the commencement of a forfeiture action or proceeding, whether
civil or criminal, which, in Lender's reasonable judgment, could result in a
forfeiture of the Mortgaged Property or otherwise materially impair the lien
created by this Instrument or Lender's interest in the Mortgaged Property;

<PAGE>   37

         (g)      any failure by Borrower to perform any of its obligations
under this Instrument (other than those specified in Sections 22(a) through
(f)), as and when required, which continues for a period of 30 days after notice
of such failure by Lender to Borrower, but no such notice or grace period shall
apply in the case of any such failure which could, in Lender's judgment, absent
immediate exercise by Lender of a right or remedy under this Instrument, result
in harm to Lender, impairment of the Note or this Instrument or any other
security given under any other Loan Document;

         (h)      any failure by Borrower to perform any of its obligations as
and when required under any Loan Document other than this Instrument which
continues beyond the applicable cure period, if any, specified in that Loan
Document; and

         (i)      any exercise by the holder of any other debt instrument
secured by a mortgage, deed of trust or deed to secure debt on the Mortgaged
Property of a right to declare all amounts due under that debt instrument
immediately due and payable.

         23.      REMEDIES CUMULATIVE. Each right and remedy provided in this
Instrument is distinct from all other rights or remedies under this Instrument
or any other Loan Document or afforded by applicable law, and each shall be
cumulative and may be exercised concurrently, independently, or successively, in
any order.

         24.      FORBEARANCE.

         (a)      Lender may (but shall not be obligated to) agree with
Borrower, from time to time, and without giving notice to, or obtaining the
consent of, or having any effect upon the obligations of, any guarantor or other
third party obligor, to take any of the following actions: extend the time for
payment of all or any part of the Indebtedness; reduce the payments due under
this Instrument, the Note, or any other Loan Document; release anyone liable for
the payment of any amounts under this Instrument, the Note, or any other Loan
Document; accept a renewal of the Note; modify the terms and time of payment of
the Indebtedness; join in any extension or subordination agreement; release any
Mortgaged Property; take or release other or additional security; modify the
rate of interest or period of amortization of the Note or change the amount of
the monthly installments payable under the Note; and otherwise modify this
Instrument, the Note, or any other Loan Document.

         (b)      Any forbearance by Lender in exercising any right or remedy
under the Note, this Instrument, or any other Loan Document or otherwise
afforded by applicable law, shall not be a waiver of or preclude the exercise of
any other right or remedy. The acceptance by Lender of payment of all or any
part of the Indebtedness after the due date of such payment, or in an amount
which is less than the required payment, shall not be a waiver of Lender's right
to require prompt

<PAGE>   38

payment when due of all other payments on account of the Indebtedness or to
exercise any remedies for any failure to make prompt payment. Enforcement by
Lender of any security for the Indebtedness shall not constitute an election by
Lender of remedies so as to preclude the exercise of any other right available
to Lender. Lender's receipt of any awards or proceeds under Sections 19 and 20
shall not operate to cure or waive any Event of Default.

         25.      LOAN CHARGES. If any applicable law limiting the amount of
interest or other charges permitted to be collected from Borrower is interpreted
so that any charge provided for in any Loan Document, whether considered
separately or together with other charges levied in connection with any other
Loan Document, violates that law, and Borrower is entitled to the benefit of
that law, that charge is hereby reduced to the extent necessary to eliminate
that violation. The amounts, if any, previously paid to Lender in excess of the
permitted amounts shall be applied by Lender to reduce the principal of the
Indebtedness. For the purpose of determining whether any applicable law limiting
the amount of interest or other charges permitted to be collected from Borrower
has been violated, all Indebtedness which constitutes interest, as well as all
other charges levied in connection with the Indebtedness which constitute
interest, shall be deemed to be allocated and spread over the stated term of the
Note. Unless otherwise required by applicable law, such allocation and spreading
shall be effected in such a manner that the rate of interest so computed is
uniform throughout the stated term of the Note.

         26.      WAIVER OF STATUTE OF LIMITATIONS. Borrower hereby waives the
right to assert any statute of limitations as a bar to the enforcement of the
lien of this Instrument or to any action brought to enforce any Loan Document.

         27.      WAIVER OF MARSHALLING. Notwithstanding the existence of any
other security interests in the Mortgaged Property held by Lender or by any
other party, Lender shall have the right to determine the order in which any or
all of the Mortgaged Property shall be subjected to the remedies provided in
this Instrument, the Note, any other Loan Document or applicable law. Lender
shall have the right to determine the order in which any or all portions of the
Indebtedness are satisfied from the proceeds realized upon the exercise of such
remedies. Borrower and any party who now or in the future acquires a security
interest in the Mortgaged Property and who has actual or constructive notice of
this Instrument waives any and all right to require the marshalling of assets or
to require that any of the Mortgaged Property be sold in the inverse order of
alienation or that any of the Mortgaged Property be sold in parcels or as an
entirety in connection with the exercise of any of the remedies permitted by
applicable law or provided in this Instrument.

         28.      FURTHER ASSURANCES. Borrower shall execute, acknowledge, and
deliver, at its sole cost and expense, all further acts, deeds, conveyances,
assignments, estoppel certificates, financing statements, transfers and
assurances as Lender may require from time to time in order to

<PAGE>   39
 better assure, grant, and convey to Lender the rights intended to be granted,
now or in the future, to Lender under this Instrument and the Loan Documents.

         29.      ESTOPPEL CERTIFICATE. Within 10 days after a request from
Lender, Borrower shall deliver to Lender a written statement, signed and
acknowledged by Borrower, certifying to Lender or any person designated by
Lender, as of the date of such statement, (i) that the Loan Documents are
unmodified and in full force and effect (or, if there have been modifications,
that the Loan Documents are in full force and effect as modified and setting
forth such modifications); (ii) the unpaid principal balance of the Note; (iii)
the date to which interest under the Note has been paid; (iv) that Borrower is
not in default in paying the Indebtedness or in performing or observing any of
the covenants or agreements contained in this Instrument or any of the other
Loan Documents (or, if the Borrower is in default, describing such default in
reasonable detail); (v) whether or not there are then existing any setoffs or
defenses known to Borrower against the enforcement of any right or remedy of
Lender under the Loan Documents; and (vi) any additional facts requested by
Lender.

         30.      GOVERNING LAW; CONSENT TO JURISDICTION AND VENUE.

         (a)      This Instrument, and any Loan Document which does not itself
expressly identify the law that is to apply to it, shall be governed by the laws
of the jurisdiction in which the Land is located (the "PROPERTY JURISDICTION").

         (b)      Borrower agrees that any controversy arising under or in
relation to the Note, this Instrument, or any other Loan Document shall be
litigated exclusively in the Property Jurisdiction. The state and federal courts
and authorities with jurisdiction in the Property Jurisdiction shall have
exclusive jurisdiction over all controversies which shall arise under or in
relation to the Note, any security for the Indebtedness, or any other Loan
Document. Borrower irrevocably consents to service, jurisdiction, and venue of
such courts for any such litigation and waives any other venue to which it might
be entitled by virtue of domicile, habitual residence or otherwise.

         31.      NOTICE.

         (a)      All notices, demands and other communications ("NOTICE") under
or concerning this Instrument shall be in writing. Each notice shall be
addressed to the intended recipient at its address set forth in this Instrument,
and shall be deemed given on the earliest to occur of (1) the date when the
notice is received by the addressee; (2) the first Business Day after the notice
is delivered to a recognized overnight courier service, with arrangements made
for payment of charges for next Business Day delivery; or (3) the third Business
Day after the notice is deposited in the United States mail with postage
prepaid, certified mail, return receipt requested. As used in this

<PAGE>   40
Section 31, the term "Business Day" means any day other than a Saturday, a
Sunday or any other day on which Lender is not open for business.

         (b)      Any party to this Instrument may change the address to which
notices intended for it are to be directed by means of notice given to the other
party in accordance with this Section 31. Each party agrees that it will not
refuse or reject delivery of any notice given in accordance with this Section
31, that it will acknowledge, in writing, the receipt of any notice upon request
by the other party and that any notice rejected or refused by it shall be deemed
for purposes of this Section 31 to have been received by the rejecting party on
the date so refused or rejected, as conclusively established by the records of
the U.S. Postal Service or the courier service.

         (c)      Any notice under the Note and any other Loan Document which
does not specify how notices are to be given shall be given in accordance with
this Section 31.

         32.      SALE OF NOTE; CHANGE IN SERVICER. The Note or a partial
interest in the Note (together with this Instrument and the other Loan
Documents) may be sold one or more times without prior notice to Borrower. A
sale may result in a change of the Loan Servicer. There also may be one or more
changes of the Loan Servicer unrelated to a sale of the Note. If there is a
change of the Loan Servicer, Borrower will be given notice of the change.

         33.      SINGLE ASSET BORROWER. Until the Indebtedness is paid in full,
Borrower (a) shall not acquire any real or personal property other than the
Mortgaged Property and personal property related to the operation and
maintenance of the Mortgaged Property; (b) shall not operate any business other
than the management and operation of the Mortgaged Property; and (c) shall not
maintain its assets in a way difficult to segregate and identify.

         34.      SUCCESSORS AND ASSIGNS BOUND. This Instrument shall bind, and
the rights granted by this Instrument shall inure to, the respective successors
and assigns of Lender and Borrower. However, a Transfer not permitted by Section
21 shall be an Event of Default.

         35.      JOINT AND SEVERAL LIABILITY. If more than one person or entity
signs this Instrument as Borrower, the obligations of such persons and entities
shall be joint and several.

         36.      RELATIONSHIP OF PARTIES; NO THIRD PARTY BENEFICIARY.

         (a)      The relationship between Lender and Borrower shall be solely
that of creditor and debtor, respectively, and nothing contained in this
Instrument shall create any other relationship between Lender and Borrower.

<PAGE>   41

         (b)      No creditor of any party to this Instrument and no other
person shall be a third party beneficiary of this Instrument or any other Loan
Document. Without limiting the generality of the preceding sentence, (1) any
arrangement (a "SERVICING ARRANGEMENT") between the Lender and any Loan Servicer
for loss sharing or interim advancement of funds shall constitute a contractual
obligation of such Loan Servicer that is independent of the obligation of
Borrower for the payment of the Indebtedness, (2) Borrower shall not be a third
party beneficiary of any Servicing Arrangement, and (3) no payment by the Loan
Servicer under any Servicing Arrangement will reduce the amount of the
Indebtedness.

         37.      SEVERABILITY; AMENDMENTS. The invalidity or unenforceability
of any provision of this Instrument shall not affect the validity or
enforceability of any other provision, and all other provisions shall remain in
full force and effect. This Instrument contains the entire agreement among the
parties as to the rights granted and the obligations assumed in this Instrument.
This Instrument may not be amended or modified except by a writing signed by the
party against whom enforcement is sought.

         38.      CONSTRUCTION. The captions and headings of the sections of
this Instrument are for convenience only and shall be disregarded in construing
this Instrument. Any reference in this Instrument to an "Exhibit" or a "Section"
shall, unless otherwise explicitly provided, be construed as referring,
respectively, to an Exhibit attached to this Instrument or to a Section of this
Instrument. All Exhibits attached to or referred to in this Instrument are
incorporated by reference into this Instrument. Any reference in this Instrument
to a statute or regulation shall be construed as referring to that statute or
regulation as amended from time to time. Use of the singular in this Agreement
includes the plural and use of the plural includes the singular. As used in this
Instrument, the term "including" means "including, but not limited to."

         39.      LOAN SERVICING. All actions regarding the servicing of the
loan evidenced by the Note, including the collection of payments, the giving and
receipt of notice, inspections of the Property, inspections of books and
records, and the granting of consents and approvals, may be taken by the Loan
Servicer unless Borrower receives notice to the contrary. If Borrower receives
conflicting notices regarding the identity of the Loan Servicer or any other
subject, any such notice from Lender shall govern.

         40.      DISCLOSURE OF INFORMATION. Lender may furnish information
regarding Borrower or the Mortgaged Property to third parties with an existing
or prospective interest in the servicing, enforcement, evaluation, performance,
purchase or securitization of the Indebtedness, including trustees, master
servicers, special servicers, rating agencies, and organizations maintaining
databases on the underwriting and performance of multifamily mortgage loans.
Borrower irrevocably waives any and all rights it may have under applicable law
to prohibit such disclosure, including any right of privacy.

<PAGE>   42

         41.      NO CHANGE IN FACTS OR CIRCUMSTANCES. All information in the
application for the loan submitted to Lender (the "LOAN APPLICATION") and in all
financial statements, rent rolls, reports, certificates and other documents
submitted in connection with the Loan Application are complete and accurate in
all material respects. There has been no material adverse change in any fact or
circumstance that would make any such information incomplete or inaccurate.

         42.      SUBROGATION. If, and to the extent that, the proceeds of the
loan evidenced by the Note are used to pay, satisfy or discharge any obligation
of Borrower for the payment of money that is secured by a pre-existing mortgage,
deed of trust or other lien encumbering the Mortgaged Property (a "PRIOR LIEN"),
such loan proceeds shall be deemed to have been advanced by Lender at Borrower's
request, and Lender shall automatically, and without further action on its part,
be subrogated to the rights, including lien priority, of the owner or holder of
the obligation secured by the Prior Lien, whether or not the Prior Lien is
released.

         43.      ACCELERATION; REMEDIES. At any time during the existence of an
Event of Default, Lender, at Lender's option, and without notice, may declare
the Indebtedness to be immediately due and payable without further demand and
may pursue any remedies permitted by applicable law or provided in this
Instrument or in any other Loan Document, including the enforcement of its
rights under this Instrument by foreclosure proceedings. Borrower has the right
to bring an action to assert the nonexistence of an Event of Default or any
other defense of Borrower to acceleration and foreclosure. Lender shall be
entitled to collect all costs and expenses incurred in pursuing such remedies,
including attorneys' fees and costs of documentary evidence, abstracts and title
reports.

         Lender shall deliver to the purchaser at a foreclosure sale, within a
reasonable time after the sale, a Lender's deed conveying the Mortgaged Property
so sold without any covenant or warranty, express or implied. The recitals in
Lender's deed shall be prima facie evidence of the truth of the statements made
therein. The proceeds of the sale shall be applied in the following order: (a)
to all costs and expenses of the sale, including attorneys' fees and costs of
title evidence; (b) to the Indebtedness in such order as Lender, in Lender's
discretion, directs; and (c) the excess, if any, to the clerk of the Circuit
Court of the county in which the sale is held.

         44.      RELEASE. Upon payment of the Indebtedness, Lender shall
release this Instrument. Borrower shall pay Lender's reasonable costs incurred
in releasing this Instrument.

         45.      ACCELERATED REDEMPTION PERIODS. Borrower hereby agrees to the
provisions of Section 846.103 of Wisconsin Statutes (or any successor provision
thereto) permitting

<PAGE>   43

Lender to elect a shortened redemption period on the conditions specified
therein in the event of a foreclosure of this Instrument

         46.      WAIVER OF TRIAL BY JURY. BORROWER AND LENDER EACH (A)
COVENANTS AND AGREES NOT TO ELECT A TRIAL BY JURY WITH RESPECT TO ANY ISSUE
ARISING OUT OF THIS INSTRUMENT OR THE RELATIONSHIP BETWEEN THE PARTIES AS
BORROWER AND LENDER THAT IS TRIABLE OF RIGHT BY A JURY AND (B) WAIVES ANY RIGHT
TO TRIAL BY JURY WITH RESPECT TO SUCH ISSUE TO THE EXTENT THAT ANY SUCH RIGHT
EXISTS NOW OR IN THE FUTURE. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS SEPARATELY
GIVEN BY EACH PARTY, KNOWINGLY AND VOLUNTARILY WITH THE BENEFIT OF COMPETENT
LEGAL COUNSEL.

         ATTACHED EXHIBITS. The following Exhibits are attached to this
Instrument:

         |X|      Exhibit A          Description of the Land (required).

                  standing all operating licenses and permits, and that it shall
                  cause to renew and extend all such required operating licenses
                  or permits, and shall not fail to take any action necessary to
                  keep all such licenses and permits in good standing and full
                  force and effect. Borrower will immediately provide Lender
                  with any notice or order which may materially adversely impact
                  the Mortgaged Property, its operations or its compliance with
                  licensing and regulatory requirements."

         19.      Section 17(b) of the Instrument is hereby amended to replace
the second sentence of Section 17(b) with the following sentence:

              "If required by Lender (whether before or after an Event of
              Default), Borrower will cause any Affiliate of Borrower to whom
              fees are payable for the management of the Mortgaged Property to
              enter into an agreement with Lender, in a form approved by Lender,
              providing for subordination of those fees and such other
              provisions as Lender may reasonably require."

         20.      The reference in Section 17(a)(5) to a residential rental
property manager shall be deemed to mean and refer to an operator of a Seniors
Housing Facility and any management company engaged thereby.

         21.      Section 18(b) of the Instrument is hereby amended to add the
following sentence at the end thereof:

                  "Prohibited Activities and Conditions also shall not include
                  the safe and lawful use and storage of medical products and
                  devices customarily used in the operation of a Seniors Housing
                  Facility."

         22.      Section 18(g) of the Instrument is hereby amended to delete
the period following the third sentence thereof and to add the following phrase
at the end of the third sentence:


<PAGE>   55

                  "provided, however, that if Lender discloses such results or
                  information to third parties in connection with the
                  enforcement of Lender's rights hereunder, such results or
                  information shall also be made available to Borrower."

         23.      Section 19 of the Instrument is hereby amended to delete
therefrom Sections 19(c) and 19(d) in their entirety and to substitute in their
place the following subsections (c) and (d) and to add at the end thereof the
following new subsection (i):

                  "(c) Borrower shall maintain at all times commercial general
                  liability insurance, workers' compensation insurance and such
                  other liability, errors and omissions and fidelity insurance
                  coverages as Lender may from time to time reasonably require,
                  provided, however, that such insurance coverages shall not
                  materially vary from the insurance coverages maintained by
                  Borrower as of the date of this Instrument.

                  (d) All insurance policies and renewals of insurance policies
                  required by this Section 19 shall be in such amounts and for
                  such periods as Lender may from time to time reasonably
                  require, provided, however, that such insurance coverages
                  shall not materially vary from the insurance coverages
                  maintained by Borrower as of the date of this Instrument, and
                  shall be issued by insurance companies reasonably satisfactory
                  to Lender.

                  (i) Notwithstanding the preceding provisions of this Section
                  19 to the contrary, in the event of any insured damage to or
                  destruction of the Mortgaged Property, or any part thereof, if
                  (A) the loss is in the aggregate amount of less than two
                  percent (2%) of the original principal balance of the Note,
                  (B) in the reasonable judgment of Lender, the Mortgaged
                  Property can be restored within six (6) months following the
                  date of the loss and (C) no Event of Default (or any event
                  which, with the giving of notice or the passage of time, or
                  both, would constitute an Event of Default) has occurred and
                  is continuing, then the proceeds of the insurance shall be
                  applied to reimburse Borrower for the cost of restoring,
                  repairing, replacing or rebuilding the Mortgaged Property or
                  part thereof subject to the insured casualty; provided,
                  however, in any event Borrower shall pay all costs of such
                  restoring, repairing, replacing or rebuilding in excess of the
                  net proceeds of insurance made available pursuant to the terms
                  of this Section 19(i)."

         24.      Section 21(a) of the Instrument is hereby amended to delete
therefrom sections (3) and (5) and to substitute in their place the following
sections (3) and (5) and to add the following section (8) at the end thereof:

                  "(3) a Transfer of a Controlling Interest in any entity
                  (unless such entity is a Publicly-Held Corporation or,
                  immediately following such Transfer, is wholly-



<PAGE>   56
                  owned by a Publicly-Held Corporation) which owns, directly or
                  indirectly through one or more intermediate entities, a
                  Controlling Interest in Borrower;

                  (5) if Key Principal is an entity, (A) a Transfer of a
                  Controlling Interest in Key Principal (unless Key Principal is
                  a Publicly-Held Corporation or, immediately following such
                  Transfer, is wholly-owned by a Publicly-Held Corporation) or
                  (B) a Transfer of a Controlling Interest in any entity (unless
                  such entity is a Publicly-Held Corporation or, immediately
                  following such Transfer is wholly-owned by a Publicly-Held
                  Corporation) which owns, directly or indirectly through one or
                  more intermediate entities, a Controlling Interest in Key
                  Principal; and,

                  (8) a Transfer to a separate entity, or change in the holder,
                  of the operating license or permit allowing the Mortgaged
                  Property to operate as a Seniors Housing facility."

         25.      Section 22 of the Instrument is hereby amended to add the
following sections (g), (h), and (i) at the end thereof:

                  "(g) any failure by Borrower to comply with the use and
                  licensing requirements set forth in Sections 10 and 11,
                  including but not limited to Borrower's loss of its license or
                  other legal authority to operate the Mortgaged Property as a
                  Seniors Housing Facility;

                  (h) any failure by Borrower to correct, within the time
                  deadlines set by any federal, state or local licensing agency,
                  any deficiency that justifies any action by such agency with
                  respect to the Mortgaged Property that may have a material
                  adverse affect on the income and operation of the Mortgaged
                  Property or Borrower's interest in the Mortgaged Property,
                  including, without limitation, a termination, revocation or
                  suspension of any applicable license, registration, permit,
                  certificate, authorization or approval necessary for the
                  operation of the Mortgaged Property as a Seniors Housing
                  Facility.

                  (i) if, without the consent of Lender: (a) Borrower ceases to
                  operate the Mortgaged Property as a Seniors Housing Facility;
                  (b) Borrower ceases to provide such kitchens (except ovens)
                  separate bathrooms, and areas for eating, sitting and sleeping
                  in each unit as are provided in the units as of the date of
                  this Instrument; (c) Borrower ceases to provide other
                  facilities and services normally associated with congregate or
                  assisted living units, including, without limitation, (i)
                  central dining services providing one to three meals per day,
                  (ii) periodic housekeeping, (iii) laundry services, and (iv)
                  customary transportation services; (d) except as required by
                  applicable law or regulation, Borrower provides or contracts
                  for skilled nursing


<PAGE>   57
                  care for any of the units; (e) non-residential space leased or
                  held available for lease to commercial tenants (i.e., space
                  other than the units, dining areas, activity rooms, lobby,
                  parlors, kitchen, mailroom, marketing/management offices)
                  exceeds ten percent (10%) of the net rental area; or, (f) the
                  Mortgaged Property is no longer classified as housing for
                  older persons pursuant to the Fair Housing Amendments Act of
                  1988, as it may be amended from time to time hereafter."

         26.      The former Sections 22 (g), (h), and (i) are hereby changed to
be Sections 22 (j), (k), and (l), respectively, and Section 22(j) is hereby
amended in the third line thereof to insert the following phrase after the word
"Borrower" and prior to the comma immediately preceding the word "but":

                  "provided, however, if such failure cannot be cured prior to
                  the expiration of such 30-day notice period, it shall not
                  constitute an Event of Default hereunder if Borrower has
                  promptly commenced cure efforts and pursues diligently to
                  completion for the period of time necessary to effect such
                  cure (which shall in no event exceed a period of 120 days
                  after notice of such failure by Lender to Borrower),"

         27.      Section 33 of the Instrument is hereby amended to read as
follows:

                  "Until the Indebtedness evidenced by the Note is paid in full,
                  Borrower shall not (1) acquire any real or personal property
                  other than the Borrower's Projects (as defined in Section 50)
                  and assets (such as accounts) related to the ownership,
                  leasing and/or operation and/or maintenance of the Borrower's
                  Projects, or (2) operate any business other than the
                  ownership, leasing and/or management and/or operation and/or
                  maintenance of the Borrower's Projects."

         28.      Section 43 of the Instrument is hereby amended to add the
following paragraph at the end thereof:

                  "In addition to the remedies set forth herein and elsewhere in
                  this Instrument, Lender upon an Event of Default shall be
                  entitled to mandate the use of a lockbox bank account, to be
                  maintained under the control and supervision of Lender, for
                  all income of the Mortgaged Property, including, but not
                  limited to, Rents, service charges, insurance payments, third
                  party provider payments including Medicare and Medicaid and
                  any other governmental or private program by which the rents
                  or occupancy charges are being paid. Lender may, upon an Event
                  of Default, cause the removal of Borrower from any Mortgaged
                  Property operations. Until such time as Lender has located a
                  replacement licensed operator, Borrower or its related or
                  affiliated entity acting as the licensed operator, for a
                  period of up to six (6) months

<PAGE>   58

                  following the date on which Lender accelerates the Note
                  secured by this Instrument, shall continue to provide all
                  required services to maintain the Mortgaged Property in full
                  compliance with all licensing and regulatory requirements as a
                  Seniors Housing Facility.  Borrower acknowledges that its
                  failure to perform this service shall constitute a form of
                  waste of the Mortgaged Property, causing irreparable harm to
                  Lender and the Mortgaged Property, and shall constitute
                  sufficient cause for the appointment of a receiver."

         29.      The following new Sections are added to the Instrument after
the last numbered Section:

                  "47.  BORROWER'S  REPRESENTATIONS AND WARRANTIES.  In addition
         to any other  representations and warranties  contained in this
         Instrument, Borrower hereby represents and warrants to Lender as
         follows:

         (a) The Mortgaged Property is duly licensed as a community-based
         residential facility and Borrower and/or Key Principal is in all
         respects otherwise legally authorized to operate the Mortgaged Property
         as a Seniors Housing Facility, under the applicable laws of the
         Property Jurisdiction;

         (b) Borrower and the Mortgaged Property (and the operation thereof) are
         in compliance in all material respects with the applicable provisions
         of all laws, statutes, regulations, ordinances, orders, standards,
         restrictions and rules of any federal, state or local government or
         quasi-government body, agency, board or authority having jurisdiction
         over the operation of the Mortgaged Property, including, without
         limitation: (a) health care and fire safety codes; (b) laws regulating
         the handling and disposal of medical or biological waste; (c) the
         applicable provisions of Seniors Housing Facility laws, rules,
         regulations and published interpretations thereof to which the Borrower
         or the Mortgaged Property is subject; and (d) all criteria established
         to classify the Mortgaged Property as housing for older persons under
         the Fair Housing Amendments Act of 1988;

         (c) If required, Borrower has a current provider agreement under any
         and all applicable federal, state and local laws for reimbursement: (a)
         to an Seniors Housing Facility; or (b) for other type of care provided
         at such facility. There is no decision not to renew any provider
         agreement related to the Mortgaged Property, nor is there any action
         pending or threatened to impose material intermediate or alternative
         sanctions with respect to the Mortgaged Property;

         (d) Borrower and the Mortgaged Property are not subject to any
         proceeding, suit or investigation by any federal, state or local
         government or quasi-government body, agency, board authority or any
         other administrative or investigative body which may result in the



<PAGE>   59

         imposition of a fine or alternative, interim or final sanction which
         would have a material adverse effect on Borrower or the operation of
         the Mortgaged Property, or which would result in the appointment of a
         receiver or manager or would result in the revocation, transfer,
         surrender, suspension or other impairment of the operating certificate,
         license, permit, approval or authorization of the Mortgaged Property to
         operate as an Seniors Housing Facility;

         (e) Upon Lender's request, copies of resident care agreements shall be
         provided to Lender. All resident records at the Mortgaged Property are
         true and correct in all material respects;

         (f) Neither the execution and delivery of the Note, the Instrument or
         the Loan Documents, Borrower's performance thereunder, nor the
         recordation of the Instrument will adversely affect the licenses,
         registrations, permits, certificates, authorizations and approvals
         necessary for the operation of the Mortgaged Property as a Seniors
         Housing Facility in the Property Jurisdiction;

         (g) Borrower is not a participant in any federal program whereby any
         federal, state or local, government or quasi-governmental body, agency,
         board or other authority may have the right to recover funds by reason
         of the advance of federal funds. Borrower has received no notice, and
         is not aware of any violation of applicable antitrust laws of any
         federal, state or local, government or quasi-government body, agency,
         board or other authority; and,

         (h) Except as otherwise specifically disclosed to the Lender in
         writing, in the event any existing management agreement is terminated
         or Lender acquires the Mortgaged Property through foreclosure or
         otherwise, neither Borrower, Lender, any subsequent manager, nor any
         subsequent purchaser (through foreclosure or otherwise) must obtain a
         certificate of need from any applicable state health care regulatory
         authority or agency (other than giving such notice required under the
         applicable state law or regulation) prior to applying for any
         applicable license, registration, permit, certificate, authorization or
         approval necessary for the operation of the Mortgaged Property as a
         Seniors Housing Facility, provided that no service or the unit
         complement is changed.

         48.       CROSS-DEFAULT AND CROSS-COLLATERALIZATION.

                           (a) In addition to the Mortgaged Property described
                   on Exhibit A attached hereto, the Borrower also owns each of
                   the senior housing facilities described on Exhibit C to this
                   Instrument. All of the properties described on Exhibit C,
                   together with the Mortgaged Property, are referred to herein
                   collectively as the "Borrower's Projects". Contemporaneous
                   with the closing and funding of the loan to the Borrower
                   evidenced by the Note, the Lender has extended additional

<PAGE>   60

                  loans to the Borrower, each loan being secured by a
                  Multifamily Mortgage or Deed of Trust, Assignment of Rents
                  and Security Agreement (a "Security Instrument") against each
                  of the other Borrower's Projects.

                           (b) The Borrower acknowledges that the Lender is
                  unwilling to extend the loan evidenced by the Note to the
                  Borrower unless the Borrower agrees that all of the Borrower's
                  Projects will be treated as a single project through the
                  imposition of cross-collateralization, cross-default and
                  release provisions. The Borrower further acknowledges that the
                  Lender's agreement to amend the single asset borrower
                  provisions of Section 33 of this Instrument, to permit the
                  Borrower's ownership of all of the Borrower's Projects, is in
                  partial consideration for the cross-collateralization,
                  cross-default and release provisions set forth herein below.

                           (c) The Borrower hereby agrees and consents that as
                  additional security to the Lender, each of the Borrower's
                  Projects shall be subject to the lien of the Lender's Security
                  Instrument for each of the other of the Borrower's Projects,
                  and that each of the respective Borrower's Projects shall
                  collateralize the other Borrower's Projects as follows: all
                  Mortgaged Property (as defined in the respective Security
                  Instrument) for each of the Borrower's Projects shall be
                  considered part of the "Mortgaged Property" under this
                  Instrument, and shall be collateral under this Instrument and
                  the Loan Documents.

                           (d) The Borrower hereby agrees and consents that upon
                  the occurrence of an Event of Default under the Security
                  Instrument securing one of the Borrower's Projects, then an
                  Event of Default shall exist under the Security Instrument
                  with respect to the other Borrower's Projects. No notice shall
                  be required to be given to the Borrower in connection with
                  such Event of Default. In the event of an Event of Default
                  under the Security Instrument with respect to any one of the
                  Borrower's Projects, the Lender shall have the right, in its
                  sole and absolute discretion, to exercise and perfect any and
                  all rights in and under the Loan Documents with regard to any
                  or all of the other Borrower's Projects, including, but not
                  limited to, an acceleration of one or all of the Notes and the
                  sale of one or all of the Borrower's Projects in accordance
                  with the terms of the respective Security Instrument. No
                  notice, except as may be required by the respective Security
                  Instrument, shall be required to be given to the Borrower in
                  connection with the Lender's exercise of any and all of its
                  rights after an Event of Default has occurred.

                           (e) The Borrower may request that Lender make a
                  determination whether any of the Borrower's Projects may be
                  released from the cross-default and

<PAGE>   61
                  cross-collateral provisions of this Section if (i) the
                  Borrower proposes to pay off an individual loan held by Lender
                  and secured by one of the Borrower's Projects, or (ii) the
                  Borrower proposes to sell one of the Borrower's Projects and
                  have the Borrower's loan on that project assumed by a buyer
                  acceptable to Lender. Upon such request from Borrower, Lender
                  shall consent to the release of the Borrower's Project from
                  the cross-default and cross-collateralization provisions of
                  this Section, provided:

                                    (1) The remaining loans to the Borrower
                           secured by the remaining Borrower's Projects that are
                           not requested to be released have, in the aggregate,
                           a minimum overall 1.40 debt service coverage, based
                           on the remaining Borrower's Projects' collective Net
                           Operating Income for the 12 months of operation
                           immediately prior to the Borrower's request for such
                           release; and

                                    (2) If the Borrower's loan is to be assumed
                           by a buyer acceptable to and approved by Lender, the
                           assumed loan must also have a minimum 1.40 debt
                           service coverage, based on that Project's Net
                           Operating Income for the 12 months of operation
                           immediately prior to the Borrower's request for such
                           release; and

                                    (3) As consideration for the Lender's
                           agreement to modify the single asset borrower
                           provisions of Section 33 of the Instrument, and
                           permit the Borrower to own all of the Borrower's
                           Projects, in the event the Borrower proposes to pay
                           off one of the Borrower's loans secured by one of the
                           Borrower's Projects by refinancing the respective
                           loan with a new lender, but not in connection with
                           the sale of the respective secured Borrower's
                           Project, the Borrower must convey the Borrower's
                           Project being refinanced to a different ownership
                           entity (with neither the specific Borrower's Project
                           or the proposed new ownership entity being owned by
                           the Borrower) prior to such refinancing, so that none
                           of the Borrower's Projects will be security for
                           financing held by any lender other than the Lender
                           that is the owner and holder of the Note.

                  For purposes of (1) and (2) of this paragraph (e), "Net
                  Operating Income" is defined as:

                                    (i) the lesser of all actual rents and other
                           income derived from the Borrower's Project sought to
                           be released from the cross-default and cross
                           collateralization provisions of this Section
                           collected for the 12 month

<PAGE>   62

                           period (net of any concession) or 95% of the gross
                           potential rental income for the 12 month period; plus

                                    (ii) all service income and other ancillary
                           income (including, without limitation, community fees
                           and fees from amenities), cable and alarm fees,
                           application fees, move-in fees, late fees and
                           forfeited deposits for the 12 month period; less

                                    (iii) the greater of the actual operating
                           expenses for the 12 month period (including the
                           required Replacement Reserves funding for the period
                           utilized by Lender in its final underwriting) or the
                           operating expenses used by Lender in its final
                           underwriting (including Replacement Reserves),
                           increased at the rate of 3% per annum.

                           (f) Notwithstanding any provision of this Section to
                  the contrary, the Borrower shall not be permitted to request a
                  release of any of the Borrower's Projects from the
                  cross-default and cross-collateral provisions of this Section
                  if, at the time of such request, a default or Event of Default
                  under any of the loans held by Lender on any of the Borrower's
                  Projects. No release of any of the Borrower's Projects from
                  the cross-default and cross-collateral provisions of this
                  Section shall be permitted by Lender unless Borrower has paid
                  all costs and expenses of Lender incurred in connection with
                  its processing of the requested release, including, without
                  limitation, all title endorsement premiums, recording fees,
                  inspection fees, and attorney fees.

                  49.      EXHIBIT C.  Exhibit C is attached to this
         Instrument."

         30.      All capitalized terms used in this Exhibit not specifically
defined herein shall have the meanings set forth in the text of the Instrument
that precedes this Exhibit.


                                      BORROWER'S INITIALS: _____________


<PAGE>   1
                                                                    EXHIBIT 10.6

                                MULTIFAMILY NOTE

US $3,786,000.00
                                                                   July 16, 1999

     FOR VALUE RECEIVED, the undersigned ("BORROWER") jointly and severally
(if more than one) promises to pay to the order of AMRESCO CAPITAL, L.P., a
Delaware limited partnership, the principal sum of THREE MILLION SEVEN HUNDRED
EIGHTY-SIX THOUSAND AND NO/100 (US $3,786,000.00), with interest on the unpaid
principal balance at the annual rate of Seven and Eighty-three hundredths
percent (7.83%).

     1.   DEFINED TERMS. As used in this Note, (i) the term "LENDER" means the
holder of this Note, and (ii) the term "INDEBTEDNESS" means the principal of,
interest on, or any other amounts due at any time under, this Note, the
Security Instrument or any other Loan Document, including prepayment premiums,
late charges, default interest, and advances to protect the security of the
Security Instrument under Section 12 of the Security Instrument. Event of
Default, Key Principal and other capitalized terms used but not defined in this
Note shall have the meanings given to such terms in the Security Instrument (as
defined in Paragraph 5).

     2.   ADDRESS FOR PAYMENT. All payments due under this Note shall be payable
at AMRESCO Services, L.P., 245 Peachtree Center Avenue, N.E., Suite 1800,
Atlanta, Georgia 30303-1231, or such other place as may be designated by
written notice to Borrower from or on behalf of Lender.

     3.   PAYMENT OF PRINCIPAL AND INTEREST. Principal and interest shall be
paid as follows:

     (a)  Unless disbursement of principal is made by Lender to Borrower on the
first day of the month, interest for the period beginning on the date of
disbursement and ending on and including the last day of the month in which such
disbursement is made shall be payable simultaneously with the execution of this
Note. Interest under this Note shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

     (b)  Consecutive monthly installments of principal and interest, each in
the amount of Twenty-Eight Thousand Seven Hundred Ninety-Five and 88/100 Dollars
(US $28,795.88), shall be payable on the first day of each month beginning on
September 1, 1999, until the entire unpaid principal balance evidenced by this
Note is fully paid. Any accrued interest remaining past due for 30 days or more
shall be added to and become part of the unpaid principal balance and shall bear
interest at the rate or rates specified in this Note, and any reference below to
"accrued interest" shall refer to accrued interest which has not become part of
the unpaid principal balance. Any remaining principal and interest shall be due
and payable on August 1, 2009 or on any earlier date on which the unpaid
principal balance of this Note becomes due and payable, by acceleration or
otherwise (the "MATURITY DATE"). The unpaid principal balance shall continue to
bear interest after the Maturity Date at the Default Rate set forth in this Note
until and including the date on which it is






<PAGE>   2




paid in full.

     (c)  Any regularly scheduled monthly installment of principal and interest
that is received by Lender before the date it is due shall be deemed to have
been received on the due date solely for the purpose of calculating interest
due.

     4.   APPLICATION OF PAYMENTS. If at any time Lender receives, from Borrower
or otherwise, any amount applicable to the Indebtedness which is less than all
amounts due and payable at such time, Lender may apply that payment to amounts
then due and payable in any manner and in any order determined by Lender, in
Lender's discretion. Borrower agrees that neither Lender's acceptance of a
payment from Borrower in an amount that is less than all amounts then due and
payable nor Lender's application of such payment shall constitute or be deemed
to constitute either a waiver of the unpaid amounts or an accord and
satisfaction.

     5.   SECURITY. The Indebtedness is secured, among other things, by a
multifamily mortgage, deed to secure debt or deed of trust dated as of the date
of this Note (the "SECURITY INSTRUMENT"), and reference is made to the Security
Instrument for other rights of Lender concerning the collateral for the
Indebtedness.

     6.   ACCELERATION. If an Event of Default has occurred and is continuing,
the entire unpaid principal balance, any accrued interest, the prepayment
premium payable under Paragraph 10, if any, and all other amounts payable under
this Note and any other Loan Document shall at once become due and payable, at
the option of Lender, without any prior notice to Borrower. Lender may exercise
this option to accelerate regardless of any prior forbearance.

     7.   LATE CHARGE. If any monthly amount payable under this Note or under
the Security Instrument or any other Loan Document is not received by Lender
within 10 days after the amount is due, Borrower shall pay to Lender,
immediately and without demand by Lender, a late charge equal to 5 percent of
such amount. Borrower acknowledges that its failure to make timely payments will
cause Lender to incur additional expenses in servicing and processing the loan
evidenced by this Note (the "LOAN"), and that it is extremely difficult and
impractical to determine those additional expenses. Borrower agrees that the
late charge payable pursuant to this Paragraph represents a fair and reasonable
estimate, taking into account all circumstances existing on the date of this
Note, of the additional expenses Lender will incur by reason of such late
payment. The late charge is payable in addition to, and not in lieu of, any
interest payable at the Default Rate pursuant to Paragraph 8.

     8.   DEFAULT RATE. So long as any monthly installment or any other payment
due under this Note remains past due for 30 days or more, interest under this
Note shall accrue on the unpaid principal balance from the earlier of the due
date of the first unpaid monthly installment or other payment due, as
applicable, at a rate (the "DEFAULT RATE") equal to the lesser of 4 percentage
points above the rate stated in the first paragraph of this Note or the maximum
interest rate which may be collected from Borrower under applicable law. If the
unpaid principal balance and all accrued






<PAGE>   3


interest are not paid in full on the Maturity Date, the unpaid principal balance
and all accrued interest shall bear interest from the Maturity Date at the
Default Rate. Borrower also acknowledges that its failure to make timely
payments will cause Lender to incur additional expenses in servicing and
processing the Loan, that, during the time that any monthly installment or
payment under this Note is delinquent for more than 30 days, Lender will incur
additional costs and expenses arising from its loss of the use of the money due
and from the adverse impact on Lender's ability to meet its other obligations
and to take advantage of other investment opportunities, and that it is
extremely difficult and impractical to determine those additional costs and
expenses. Borrower also acknowledges that, during the time that any monthly
installment or other payment due under this Note is delinquent for more than 30
days, Lender's risk of nonpayment of this Note will be materially increased and
Lender is entitled to be compensated for such increased risk. Borrower agrees
that the increase in the rate of interest payable under this Note to the Default
Rate represents a fair and reasonable estimate, taking into account all
circumstances existing on the date of this Note, of the additional costs and
expenses Lender will incur by reason of the Borrower's delinquent payment and
the additional compensation Lender is entitled to receive for the increased
risks of nonpayment associated with a delinquent loan.

     9.   LIMITS ON PERSONAL LIABILITY.

     (a)  Except as otherwise provided in this Paragraph 9, Borrower shall
have no personal liability under this Note, the Security Instrument or any other
Loan Document for the repayment of the Indebtedness or for the performance of
any other obligations of Borrower under the Loan Documents, and Lender's only
recourse for the satisfaction of the Indebtedness and the performance of such
obligations shall be Lender's exercise of its rights and remedies with respect
to the Mortgaged Property and any other collateral held by Lender as security
for the Indebtedness. This limitation on Borrower's liability shall not limit or
impair Lender's enforcement of its rights against any guarantor of the
Indebtedness or any guarantor of any obligations of Borrower.

     (b)  Borrower shall be personally liable to Lender for the repayment of a
portion of the Indebtedness equal to any loss or damage suffered by Lender as a
result of (1) failure of Borrower to pay to Lender upon demand after an Event of
Default. All Rents to which Lender is entitled under Section 3(a) of the
Security Instrument and the amount of all security deposits collected by
Borrower from tenants then in residence; (2) failure of Borrower to apply all
insurance proceeds and condemnation proceeds as required by the Security
Instrument; (3) failure of Borrower to comply with Section 14(d) or (e) of the
Security Instrument relating to the delivery of books and records, statements,
schedules and reports; (4) fraud or written material misrepresentation by
Borrower, Key Principal or any officer, director, partner, member or employee of
Borrower in connection with the application for or creation of the Indebtedness
or any request for any action or consent by Lender; or (5) failure to apply
Rents, first, to the payment of reasonable operating expenses (other than
Property management fees that are not currently payable pursuant to the terms of
an Assignment of Management Agreement or any other agreement with Lender
executed in connection with the Loan) and then to amounts ("DEBT SERVICE
AMOUNTS") payable under this Note, the Security Instrument or any other Loan
Document (except that Borrower will not be






<PAGE>   4




personally liable (i) to the extent that Borrower lacks the legal right to
direct the disbursement of such sums because of a bankruptcy, receivership or
similar judicial proceeding, or (ii) with respect to Rents that are distributed
in any calendar year if Borrower has paid all operating expenses and Debt
Service Amounts for that calendar year).

     (c)  Borrower shall become personally liable to Lender for the repayment of
all of the Indebtedness upon the occurrence of any of the following Events of
Default: (1) Borrowers acquisition of any property or operation of any business
not permitted by Section 33 of the Security Instrument; or (2) a Transfer that
is an Event of Default under Section 21 of the Security Instrument.

     (d)  To the extent that Borrower has personal liability under this
Paragraph 9, Lender may exercise its rights against Borrower personally without
regard to whether Lender has exercised any rights against the Mortgaged Property
or any other security, or pursued any rights against any guarantor, or pursued
any other rights available to Lender under this Note, the Security Instrument,
any other Loan Document or applicable law. For purposes of this Paragraph 9, the
term "MORTGAGED PROPERTY" shall not include any funds that (1) have been applied
by Borrower as required or permitted by the Security Instrument prior to the
occurrence of an Event of Default, or (2) Borrower was unable to apply as
required or permitted by the Security Instrument because of a bankruptcy,
receivership, or similar judicial proceeding.

     10.  VOLUNTARY AND INVOLUNTARY PREPAYMENTS.

     (a)  A prepayment premium shall be payable in connection with any
prepayment made under this Note as provided below:

          (1)   Borrower may voluntarily prepay all (but not less than all) of
     the unpaid principal balance of this Note on the last Business Day of a
     calendar month if Borrower has given Lender at least 30 days prior notice
     of its intention to make such prepayment. Such prepayment shall be made by
     paying (A) the amount of principal being prepaid, (B) all accrued interest,
     (C) all other sums due Lender at the time of such prepayment, and (D) the
     prepayment premium calculated pursuant to Schedule A. For all purposes,
     including the accrual of interest, any prepayment received by Lender on any
     day other than the last calendar day of the month shall be deemed to have
     been received on the last calendar day of such month. For purposes of this
     Note, a "BUSINESS DAY" means any day other than a Saturday, Sunday or any
     other day on which Lender is not open for business.

          (2)   Upon Lender's exercise of any right of acceleration under this
      Note, Borrower shall pay to Lender, in addition to the entire unpaid
     principal balance of this Note outstanding at the time of the acceleration,
     (A) all accrued interest and all other sums due Lender under this Note and
     the other Loan Documents, and (B) the prepayment premium calculated
     pursuant to Schedule A.







<PAGE>   5




          (3)   Any application by Lender of any collateral or other security to
     the repayment of any portion of the unpaid principal balance of this Note
     prior to the Maturity Date and in the absence of acceleration shall be
     deemed to be a partial prepayment by Borrower, requiring the payment to
     Lender by Borrower of a prepayment premium. The amount of any such partial
     prepayment shall be computed so as to provide to Lender a prepayment
     premium computed pursuant to Schedule A without Borrower having to pay
     out-of-pocket any additional amounts.

     (b)  Notwithstanding the provisions of Paragraph 10(a), no prepayment
premium shall be payable with respect to (A) any prepayment made no more than 90
days before the Maturity Date, or (B) any prepayment occurring as a result of
the application of any insurance proceeds or condemnation award under the
Security Instrument.

     (c)  Schedule A is hereby incorporated by reference into this Note.

     (d)  Any required prepayment of less than the unpaid principal balance of
this Note shall not extend or postpone the due date of any subsequent monthly
installments or change the amount of such installments, unless Lender agrees
otherwise in writing.

     (e)  Borrower recognizes that any prepayment of the unpaid principal
balance of this Note, whether voluntary or involuntary or resulting from a
default by Borrower, will result in Lender's incurring loss, including
reinvestment loss, additional expense and frustration or impairment of Lender's
ability to meet its commitments to third parties. Borrower agrees to pay to
Lender upon demand damages for the detriment caused by any prepayment, and
agrees that it is extremely difficult and impractical to ascertain the extent of
such damages. Borrower therefore acknowledges and agrees that the formula for
calculating prepayment premiums set forth on Schedule A represents a reasonable
estimate of the damages Lender will incur because of a prepayment.

     (f)  Borrower further acknowledges that the prepayment premium provisions
of this Note are a material part of the consideration for the loan evidenced by
this Note, and acknowledges that the terms of this Note are in other respects
more favorable to Borrower as a result of the Borrower's voluntary agreement to
the prepayment premium provisions.

     11.  COSTS AND EXPENSES. Borrower shall pay on demand all expenses and
costs, including fees and out-of-pocket expenses of attorneys and expert
witnesses and costs of investigation, incurred by Lender as a result of any
default under this Note or in connection with efforts to collect any amount due
under this Note, or to enforce the provisions of any of the other Loan
Documents, including those incurred in post-judgment collection efforts and in
any bankruptcy proceeding (including any action for relief from the automatic
stay of any bankruptcy proceeding) or judicial or non-judicial foreclosure
proceeding.

     12.  FORBEARANCE.  Any forbearance by Lender in exercising any right or
remedy under






<PAGE>   6
this Note, the Security Instrument, or any other Loan Document or otherwise
afforded by applicable law, shall not be a waiver of or preclude the exercise of
that or any other right or remedy. The acceptance by Lender of any payment after
the due date of such payment, or in an amount which is less than the required
payment, shall not be a waiver of Lender's right to require prompt payment when
due of all other payments or to exercise any right or remedy with respect to any
failure to make prompt payment. Enforcement by Lender of any security for
Borrower's obligations under this Note shall not constitute an election by
Lender of remedies so as to preclude the exercise of any other right or remedy
available to Lender.

     13.  WAIVERS. Presentment, demand, notice of dishonor, protest, notice of
acceleration, notice of intent to demand or accelerate payment or maturity,
presentment for payment, notice of nonpayment, grace, and diligence in
collecting the Indebtedness are waived by Borrower, Key Principal, and all
endorsers and guarantors of this Note and all other third party obligors.

     14.  LOAN CHARGES. Borrower agrees to pay an effective rate of interest
equal to the sum of the interest rate provided for in this Note and any
additional rate of interest resulting from any other charges of interest or in
the nature of interest paid or to be paid in connection with the loan evidenced
by this Note and any other fees or amounts to be paid by Borrower pursuant to
any of the other Loan Documents. Neither this Note nor any of the other Loan
Documents shall be construed to create a contract for the use, forbearance or
detention of money requiring payment of interest at a rate greater than the
maximum interest rate permitted to be charged under applicable law. If any
applicable law limiting the amount of interest or other charges permitted to be
collected from Borrower in connection with the Loan is interpreted so that any
interest or other charge provided for in any Loan Document, whether considered
separately or together with other charges provided for in any other Loan
Document, violates that law, and Borrower is entitled to the benefit of that
law, that interest or charge is hereby reduced to the extent necessary to
eliminate that violation. The amounts, if any, previously paid to Lender in
excess of the permitted amounts shall be applied by Lender to reduce the unpaid
principal balance of this Note. For the purpose of determining whether any
applicable law limiting the amount of interest or other charges permitted to be
collected from Borrower has been violated, all Indebtedness that constitutes
interest, as well as all other charges made in connection with the Indebtedness

                ACKNOWLEDGMENT AND AGREEMENT OF KEY PRINCIPAL TO
           PERSONAL LIABILITY FOR EXCEPTIONS TO NON-RECOURSE LIABILITY

     Key Principal, who has an economic interest in Borrower or who will
otherwise obtain a material financial benefit from the Loan, hereby absolutely,
unconditionally and irrevocably agrees to pay to Lender, or its assigns, on
demand, all amounts for which Borrower is personally liable under Paragraph 9 of
the Multifamily Note to which this Acknowledgment is attached (the "NOTE"). The
obligations of Key Principal shall survive any foreclosure proceeding, any
foreclosure sale, any delivery of any deed in lieu of foreclosure, and any
release of record of the Security Instrument. Lender may pursue its remedies
against Key Principal without first exhausting its remedies against the Borrower
or the Mortgaged Property. All capitalized terms used but not defined in this
Acknowledgment shall have the meanings given to such terms in the Security
Instrument. As used in this Acknowledgment, the term "Key Principal" (each if
more than one) shall mean only those individuals or entities that execute this
Acknowledgment.

     The obligations of Key Principal shall be performed without demand by
Lender and shall be unconditional irrespective of the genuineness, validity, or
enforceability of the Note, or any other Loan Document, and without regard to
any other circumstance which might otherwise constitute a legal or equitable
discharge of a surety or a guarantor. Key Principal hereby waives the benefit of
all principles or provisions of law, which are or might be in conflict with the
terms of this Acknowledgment, and agrees that Key Principal's obligations shall
not be affected by any circumstances which might otherwise constitute a legal or
equitable discharge of a surety or a guarantor. Key Principal hereby waives the
benefits of any right of discharge and all other rights under any and all
statutes or other laws relating to guarantors or sureties, to the fullest extent
permitted by law, diligence in collecting the Indebtedness, presentment, demand
for payment, protest, all notices with respect to the Note including this
Acknowledgment, which may be required by statute, rule of law or otherwise to
preserve Lender's rights against Key Principal under this Acknowledgment,
including notice of acceptance, notice of any amendment of the Loan Documents,
notice of the occurrence of any default or Event of Default, notice of intent to
accelerate, notice of acceleration, notice of dishonor, notice of foreclosure,
notice of protest, notice of the incurring by Borrower of any obligation or
indebtedness and all rights to require Lender to (a) proceed against Borrower,
(b) proceed against any general partner of Borrower, (c) proceed against or
exhaust any collateral held by Lender to secure the repayment of the
Indebtedness, or (d) if Borrower is a partnership, pursue any other remedy it
may have against Borrower, or any general partner of Borrower. In addition, Key
Principal waives, to the fullest extent allowed by applicable law, all of Key
Principal's rights under Chapter 846, Wis. Statutes, including ss. 846.103.

     At any time without notice to Key Principal, and without affecting the
liability of Key Principal hereunder, (a) the time for payment of the principal
of or interest on the Indebtedness may be extended or the Indebtedness may be
renewed in whole or in part; (b) the time for Borrower's performance of or
compliance with any covenant or agreement contained in the Note, or any other
Loan Document, whether presently existing or hereinafter entered into, may be
extended or such performance or compliance may be waived; (c) the maturity of
the Indebtedness may be accelerated






<PAGE>   11


as provided in the Note or any other Loan Document; (d) the Note or any other
Loan Document may be modified or amended by Lender and Borrower in any respect,
including an increase in the principal amount; and (e) any security for the
Indebtedness may be modified, exchanged, surrendered or otherwise dealt with or
additional security may be pledged or mortgaged for the Indebtedness.

     Key Principal acknowledges that Key Principal has received a copy of the
Note and all other Loan Documents. Neither this Acknowledgment nor any of its
provisions may be waived, modified, amended, discharged, or terminated except by
an agreement in writing signed by the party against which the enforcement of the
waiver, modification, amendment, discharge, or termination is sought, and then
only to the extent set forth in that agreement. Key Principal agrees to notify
Lender (in the manner for giving notices provided in Section 31 of the Security
Instrument) of any change of Key Principal's address within 10 Business Days
after such change of address occurs. Any notices to Key Principal shall be given
in the manner provided in Section 31 of the Security Instrument. Key Principal
agrees to be bound by Paragraphs 20 and 21 of the Note.

     THIS  ACKNOWLEDGMENT  IS AN  INSTRUMENT  SEPARATE  FROM,  AND NOT A PART
OF, THE NOTE. BY SIGNING THIS ACKNOWLEDGMENT, KEY PRINCIPAL DOES NOT INTEND TO
BECOME AN ACCOMMODATION PARTY TO, OR AN ENDORSER OF, THE NOTE.

     IN WITNESS WHEREOF, Key Principal has signed and delivered this
Acknowledgment or has caused this Acknowledgment to be signed and delivered by
its duly authorized representative.

                               PREPAYMENT PREMIUM

     Any prepayment premium payable under Paragraph 10 of this Note shall be
computed as follows:

     (a)  If the prepayment is made during the first nine and one-half (9.5)
          years beginning on the date of the Note (the "YIELD MAINTENANCE
          PERIOD"), the prepayment premium shall be the greater of:

          (i)     I % of the unpaid principal balance of this Note; or

          (ii)    The product obtained by multiplying:

                  (A)     the amount of principal being prepaid,

                  by

                  (B)     the difference obtained by subtracting from the
                          interest rate on this Note the yield rate (the "YIELD
                          RATE") on the 5.50% U.S. Treasury Security due May,
                          2009 (the "SPECIFIED U.S. TREASURY SECURITY"), as the
                          Yield Rate is reported in The Wall Street Journal on
                          the fifth Business Day preceding (x) the date notice
                          of prepayment is given to Lender where prepayment is
                          voluntary, or (y) the date Lender accelerates the
                          Loan,

                  by

                  (C)     the present value factor calculated using the
                          following formula:

                                         1-(1 + r)-n
                                         -----------

                                              (or  366-day years, if
                                              applicable), and any fraction
                                              thereof, remaining between
                                              the Prepayment Date and the
                                              expiration of the Yield
                                              Maintenance Period]






<PAGE>   13


                                   In the event that no Yield Rate is published
                                   for the Specified U.S. Treasury Security,
                                   then the nearest equivalent U.S. Treasury
                                   Security shall be selected at Lender's
                                   discretion. If the publication of such Yield
                                   Rates in The Wall Street Journal is
                                   discontinued, Lender shall determine such
                                   Yield Rates from another source selected by
                                   Lender.

                                   For purposes of subparagraph (ii)(C), the
                                   "PREPAYMENT DATE" shall be (x) in the case of
                                   a voluntary prepayment, the date on which the
                                   prepayment is made, and (y) in any other
                                   case, the date on which Lender accelerates
                                   the unpaid principal balance of this Note.

     (b)  If the prepayment is made after the expiration of the Yield
          Maintenance Period but more than 90 days before the Maturity Date, the
          prepayment premium shall be 1% of the unpaid principal balance of this
          Note.

                  (b)      Revolving Loan Borrowings.

                           (i) Notice of Borrowing. A Designated Borrower shall
                  request a Revolving Loan borrowing by written notice (or
                  telephonic notice promptly confirmed in writing) to the
                  Administrative Agent not later than 11:00 A.M. (Charlotte,
                  North Carolina time) on the sixth Business Day prior to the
                  date of the requested borrowing in the case of Base Rate Loans
                  (other than the initial borrowing of Base Rate Loans on the
                  Closing Date which will require notice to be delivered on the
                  Closing Date), and on the eighth Business Day prior to the
                  date of the requested borrowing in the case of Eurodollar
                  Loans. Each such request for borrowing shall be irrevocable
                  and shall specify (A) that a Revolving Loan is requested, (B)
                  the date of the requested borrowing (which shall be a Business
                  Day), (C) the aggregate principal amount to be borrowed, (D) a
                  breakdown of (I) the amount of such Revolving Loan which each
                  applicable Borrower is actually borrowing and (II) the
                  Eligible Project for which each such portion of the Revolving
                  Loan is being used, and (E) whether the borrowing shall be
                  comprised of Base Rate Loans, Eurodollar Loans or a
                  combination thereof, and if Eurodollar Loans are requested,
                  the Interest Period(s) therefor. Each Notice of Borrowing
                  shall also be accompanied by (x) copies of invoices
                  substantiating the soft costs of the Borrowers and (y) a
                  schedule designating which Eligible Projects and which
                  expenditure categories with respect to

                                       28

<PAGE>   34
                  such Eligible Projects such Revolving Loans will be used to
                  pay by the applicable Borrowers; provided, however, subject to
                  the terms of Section 8.15, a Revolving Loan advance may be
                  used by an applicable Borrower to make payment on a specific
                  expenditure category in an amount in excess of the amount
                  designated for such expenditure category in the applicable
                  Development Budget, so long as there has been a demonstrated
                  cost savings in one or more specific expenditure categories in
                  an amount equal to or greater than such excess payment. If a
                  Designated Borrower shall fail to specify in any such Notice
                  of Borrowing (I) an applicable Interest Period in the case of
                  a Eurodollar Loan, then such notice shall be deemed to be a
                  request for an Interest Period of one month, or (II) the type
                  of Revolving Loan requested, then such notice shall be deemed
                  to be a request for a Base Rate Loan hereunder. The
                  Administrative Agent shall give notice to each affected Lender
                  promptly upon receipt of each Notice of Borrowing pursuant to
                  this Section 2.1(b)(i), the contents thereof and each such
                  Lender's share of any borrowing to be made pursuant thereto.

                           (ii) Minimum Amounts. Each Base Rate Loan shall be in
                  a minimum aggregate principal amount of $500,000 and integral
                  multiples of $100,000 in excess thereof (or the remaining
                  amount of the Revolving Committed Amount, if less). Each
                  Eurodollar Loan shall be in a minimum aggregate principal of
                  $1,000,000 and integral multiples of $100,000 in excess
                  thereof (or the remaining amount of the Revolving Committed
                  Amount, if less).

                           (iii) Advances. Each Lender will make its Revolving
                  Commitment Percentage of each Revolving Loan borrowing
                  available to the Administrative Agent for the account of a
                  Borrower as specified in Section 3.15(a), or in such other
                  manner as the Administrative Agent may specify in writing, by
                  11:00 A.M. (Charlotte, North Carolina time) on the date
                  specified in the applicable Notice of Borrowing in Dollars and
                  in funds immediately available to the Administrative Agent.
                  Such borrowing will then be made available to the Designated
                  Borrowers by the Administrative Agent on the date specified in
                  the applicable Notice of Borrowing by crediting the account of
                  the Designated Borrowers on the books of such office with the
                  aggregate of the amounts made available to the Administrative
                  Agent by the Lenders and in like funds as received by the
                  Administrative Agent.

                           (iv) Development Fees. The Lenders will make Loan
                  advances to reimburse the appropriate Borrowers' development
                  fees owing to HCR and/or Alterra with respect to the Eligible
                  Projects; provided, however with respect to any development
                  fees owing to HCR and/or Alterra on Eligible Projects which
                  have not been fully constructed, Loan advances to reimburse
                  such development fees will be made in the following manner:

                                (A) From and after such time as site zoning and
                           permitting and site acquisition have occurred with
                           respect to an Eligible Project, the Borrower may use
                           Loan proceeds in an amount up to 5% of the applicable
                           projected all-in project costs as set forth in the
                           applicable Development

                                       29
<PAGE>   35
                           Budget with respect to an Eligible Project to pay the
                           development fee with respect to an Eligible Project;
                           and

                                    (B) From and after such time as a
                           certificate of occupancy has been issued for an
                           Eligible Project, the Borrower may use Loan proceeds
                           to pay development fees with respect to such Eligible
                           Project in an amount equal to the difference between
                           (I) 7% of the applicable projected all-in project
                           costs as set forth in the applicable Development
                           Budget with respect to an Eligible Project minus (II)
                           the amount of Loan proceeds used to pay the
                           development fees with respect to such Eligible
                           Project pursuant to subsection (iv)(A) above.

                           Provided, however, it is understood and agreed that
                           Loan advances used to pay development fees with
                           respect to an Eligible Project shall not exceed 7% of
                           the applicable projected all-in project costs on such
                           Eligible Project.

                  (c)      Repayment. The principal amount of all Revolving
                  Loans shall be due and payable in full on the Maturity Date,
                  unless accelerated sooner pursuant to Section 9.2.

                  (d)      Interest.  Subject to the provisions of Section 3.1,

                           (i) Base Rate Loans. During such periods as Revolving
                  Loans shall be comprised in whole or in part of Base Rate
                  Loans, such Base Rate Loans shall bear interest at a per annum
                  rate equal to the Adjusted Base Rate.

                           (ii) Eurodollar Loans. During such periods as
                  Revolving Loans shall be comprised in whole or in part of
                  Eurodollar Loans, such Eurodollar Loans shall bear interest at
                  a per annum rate equal to the Adjusted Eurodollar Rate.

         Interest on Revolving Loans shall be payable in arrears on each
         applicable Interest Payment Date (or at such other times as may be
         specified herein).

                  (e)      Revolving Notes. The Revolving Loans made by each
         Lender shall be evidenced by a duly executed promissory note of the
         Borrowers to such Lender in an original principal amount equal to such
         Lender's Revolving Commitment Percentage of the Revolving Committed
         Amount and in substantially the form of Exhibit 2.1(e).

         2.2      EXTENSION OF MATURITY DATE.

                  (a)      First Extension. Not more than 15 months and not less
         than 90 days prior to the date occurring three years from the Closing
         Date, the Credit Parties may request in writing that the Lenders extend
         the Maturity Date for an additional one year period (the "First
         Extended Maturity Date"). The Maturity Date shall be extended for an
         additional one year period if (i) each of the Lenders has approved such
         extension in writing and (ii) the Borrowers shall have paid to each
         Lender an extension fee in an amount equal to 0.15% of the Revolving
         Commitment of each Lender.

                                       30

<PAGE>   36

                  (b)      Second Extension. If the Maturity Date has been
         extended to the First Extended Maturity Date, not more than 12 months
         and not less than 90 days prior to the First Extended Maturity Date,
         the Credit Parties may request in writing that the Lenders extend the
         Maturity Date for a second one year period. The Maturity Date shall be
         extended for a second one year period (the "Second Extended Maturity
         Date") if (i) each of the Lenders has approved such extension in
         writing and (ii) the Borrowers shall have paid to each Lender an
         extension fee in an amount equal to 0.15% of the Revolving Commitment
         of each Lender.

         2.3      ADDITIONAL BORROWERS.

         The Parent may request designation of any Person (an "Applicant
Borrower") as a Borrower hereunder by delivery of such a request to the
Administrative Agent together with a Joinder Agreement executed by such
Applicant Borrower in substantially the form attached as Exhibit 2.3(i). Such
request shall include a designation of whether such Borrower will be a Pool A
Borrower, a Pool B Borrower or a Pool C Borrower. The Administrative Agent will
promptly notify the Lenders of any such request together with a copy of the
Joinder Agreement executed by the Applicant Borrower. The joinder of each
Applicant Borrower as a Borrower will be subject to (i) delivery of executed

incorporation or organization, as applicable, bylaws, operating agreement or
partnership agreement, incumbency certificates, opinions of counsel and such
other items as the Administrative Agent and the Required Lenders may reasonably

under the Credit Documents, (v) delivery to the Administrative Agent of all
items identified in Section 5.3 with respect to the Facility of such Applicant
Borrower (in form, content and scope satisfactory to the Administrative Agent)
and all other items necessary to qualify the Facility of such Borrower as an
Eligible Project, (vi) delivery by an officer of the Parent, in its capacity as
general partner of such Applicant Borrower, of an officer's certificate in

may reasonably request in connection with the foregoing, including, without

thereupon become a party hereto and a Borrower hereunder and shall be (i)
entitled to all rights and benefits of a Borrower hereunder and under each

         2.4      JOINT AND SEVERAL LIABILITY AMONG POOL BORROWERS.

                  (a)      Pool A Borrowers.

                           (i) Each of the Pool A Borrowers is accepting joint
                  and several liability hereunder for the Pool A Obligations in
                  consideration of the financial accommodation to be provided by
                  the Lenders under this Credit Agreement, for the mutual
                  benefit, directly and indirectly, of each of the Pool A
                  Borrowers and in consideration of the undertakings of each of
                  the Pool A Borrowers to accept joint and several liability for
                  the obligations of each of them.

                           (ii) Each of the Pool A Borrowers jointly and
                  severally hereby irrevocably and unconditionally accepts, not
                  merely as a surety but also as a co-debtor, joint and several
                  liability with the other Pool A Borrowers with respect to the
                  payment and performance of all of the Pool A Obligations
                  arising under this Credit Agreement and the other Credit
                  Documents, it being the intention of the parties hereto that
                  all the Pool A Obligations shall be the joint and several
                  obligations of each of the Pool A Borrowers without
                  preferences or distinction among them.

                           (iii) If and to the extent that any of the Pool A
                  Borrowers shall fail to make any payment with respect to any
                  of the Pool A Obligations hereunder as and when due or to
                  perform any of such obligations in accordance with the terms
                  thereof (including, without limitation, any applicable cure
                  periods), then in each such event, the other Pool A Borrowers
                  will make such payment with respect to, or perform, such
                  obligation.

                           (iv) The obligations of each Pool A Borrower under
                  the provisions of this Section 2.4(a) constitute full recourse
                  obligations of such Pool A Borrower, enforceable against it to
                  the full extent of its properties and assets, irrespective of
                  the validity, regularity or enforceability of this Credit
                  Agreement or any other circumstances whatsoever.

                           (v) Except as otherwise expressly provided herein,
                  each Pool A Borrower hereby waives notice of acceptance of its
                  joint and several liability, notice (except to the extent
                  notice is expressly required to be given pursuant to the terms
                  of this Credit Agreement) of occurrence of any Default or
                  Event of Default, or of any demand for any payment under this
                  Credit Agreement, notice of any action at any time taken or
                  omitted by the Lender under or in respect of any of the Pool A
                  Obligations hereunder, any requirement of diligence and,
                  generally, all demands, notices and other formalities of every
                  kind in connection with this Credit Agreement. With respect to
                  its obligations under this Section 2.4(a), each Pool A
                  Borrower hereby assents to, and waives notice of, any
                  extension or postponement of the time for the payment of any
                  of the Pool A Obligations hereunder, the acceptance of any
                  partial payment thereon, any waiver, consent or other action
                  or acquiescence by the Lenders at any time or times in respect
                  of any

                                       32

<PAGE>   38

                  default by any other Pool A Borrower in the performance or
                  satisfaction of any term, covenant, condition or provision of
                  this Credit Agreement, any and all other indulgences
                  whatsoever by the Lenders in respect of any of the Pool A
                  Obligations hereunder, and the taking, addition, substitution
                  or release, in whole or in part, at any time or times, of any
                  security for any of such Pool A Obligations or the addition,
                  substitution or release, in whole or in part, of any Pool A
                  Borrower. Without limiting the generality of the foregoing,
                  each Pool A Borrower assents to any other action or delay in
                  acting or any failure to act on the part of the Lender,
                  including, without limitation, any failure strictly or
                  diligently to assert any right or to pursue any remedy or to
                  comply fully with applicable laws or regulations thereunder
                  which might, but for the provisions of this Section 2.4(a),
                  afford grounds for terminating, discharging or relieving such
                  Pool A Borrower, in whole or in part, from any of its
                  obligations under this Section 2.4(a), it being the intention
                  of each Pool A Borrower that, so long as any of the Pool A
                  Obligations hereunder remain unsatisfied, the obligations of
                  such Pool A Borrower under this Section 2.4(a) shall not be
                  discharged except by performance and then only to the extent
                  of such performance. The obligations of each Pool A Borrower
                  under this Section 2.4(a) shall not be diminished or rendered
                  unenforceable by any winding up, reorganization, arrangement,
                  liquidation, reconstruction or similar proceeding with respect
                  to any reconstruction or similar proceeding with respect to
                  any Pool A Borrower or any Lender. The joint and several
                  liability of the Pool A Borrowers hereunder shall continue in
                  full force and effect notwithstanding any absorption, merger,
                  amalgamation or any other change whatsoever in the name,
                  membership, constitution or place of formation of any Pool A
                  Borrower or any Lender.

                           (vi) The provisions of this Section 2.4(a) are made
                  for the benefit of the Administrative Agent and the Lenders
                  and their respective successors and assigns, and may be
                  enforced by any such Person from time to time against any of
                  the Pool A Borrowers as often as occasion therefor may arise
                  and without requirement on the part of any Lender first to
                  marshal any of its claims or to exercise any of its rights
                  against any of the other Pool A Borrowers or to exhaust any
                  remedies available to it against any of the other Pool A
                  Borrowers or to resort to any other source or means of
                  obtaining payment of any of the Pool A Obligations or to elect
                  any other remedy. The provisions of this Section 2.4(a) shall
                  remain in effect until all the Pool A Obligations hereunder
                  shall have been paid in full or otherwise fully satisfied. If
                  at any time, any payment, or any part thereof, made in respect
                  of any of the Pool A Obligations, is rescinded or must
                  otherwise be restored or returned by the Lenders upon the
                  insolvency, bankruptcy or reorganization of any of the Pool A
                  Borrowers, or otherwise, the provisions of this Section 2.4(a)
                  will forthwith be reinstated and in effect as though such
                  payment had not been made.

                           (vii) Notwithstanding any provision to the contrary
                  contained herein or in any other of the Credit Documents or
                  Hedging Agreements of the Pool A Borrowers, the obligations of
                  each Pool A Borrower hereunder shall be limited to

                                       33

                  an aggregate amount equal to the largest amount that would not
                  render its obligations hereunder subject to avoidance under
                  Section 548 of the Bankruptcy Code or any comparable
                  provisions of any applicable state law.

                           (viii) Notwithstanding anything to the contrary
                  contained in any Credit Document, each of the parties hereto
                  agrees that the Pool A Borrowers shall not have any liability
                  for the Pool B Obligations and Pool C Obligations.

                  (b)      Pool B Borrowers.

                           (i) Each of the Pool B Borrowers is accepting joint
                  and several liability hereunder for the Pool B Obligations in
                  consideration of the financial accommodation to be provided by
                  the Lenders under this Credit Agreement, for the mutual
                  benefit, directly and indirectly, of each of the Pool B
                  Borrowers and in consideration of the undertakings of each of
                  the Pool B Borrowers to accept joint and several liability for
                  the obligations of each of them.

                           (ii) Each of the Pool B Borrowers jointly and
                  severally hereby irrevocably and unconditionally accepts, not
                  merely as a surety but also as a co-debtor, joint and several
                  liability with the other Pool B Borrowers with respect to the
                  payment and performance of all of the Pool B Obligations
                  arising under this Credit Agreement and the other Credit
                  Documents, it being the intention of the parties hereto that
                  all the Pool B Obligations shall be the joint and several
                  obligations of each of the Pool B Borrowers without
                  preferences or distinction among them.

                           (iii) If and to the extent that any of the Pool B
                  Borrowers shall fail to make any payment with respect to any
                  of the Pool B Obligations hereunder as and when due or to
                  perform any of such obligations in accordance with the terms
                  thereof (including, without limitation, any applicable cure
                  periods), then in each such event, the other Pool B Borrowers
                  will make such payment with respect to, or perform, such
                  obligation.

                           (iv) The obligations of each Pool B Borrower under
                  the provisions of this Section 2.4(b) constitute full recourse
                  obligations of such Pool B Borrower, enforceable against it to
                  the full extent of its properties and assets, irrespective of
                  the validity, regularity or enforceability of this Credit
                  Agreement or any other circumstances whatsoever.

                           (v) Except as otherwise expressly provided herein,
                  each Pool B Borrower hereby waives notice of acceptance of its
                  joint and several liability, notice (except to the extent
                  notice is expressly required to be given pursuant to the terms
                  of this Credit Agreement) of occurrence of any Default or
                  Event of Default, or of any demand for any payment under this
                  Credit Agreement, notice of any action at any time taken or
                  omitted by the Lender under or in respect of any of the Pool B
                  Obligations hereunder, any requirement of diligence and,
                  generally, all
                                       34

                  demands, notices and other formalities of every kind in
                  connection with this Credit Agreement. Each Pool B Borrower
                  hereby assents to, and waives notice of, any extension or
                  postponement of the time for the payment of any of the Pool B
                  Obligations hereunder, the acceptance of any partial payment
                  thereon, any waiver, consent or other action or acquiescence
                  by the Lenders at any time or times in respect of any default
                  by any other Pool B Borrower in the performance or
                  satisfaction of any term, covenant, condition or provision of
                  this Credit Agreement, any and all other indulgences
                  whatsoever by the Lenders in respect of any of the Pool B
                  Obligations hereunder, and the taking, addition, substitution
                  or release, in whole or in part, at any time or times, of any
                  security for any of such Pool B Obligations or the addition,
                  substitution or release, in whole or in part, of any Pool B
                  Borrower. Without limiting the generality of the foregoing,
                  each Pool B Borrower assents to any other action or delay in
                  acting or any failure to act on the part of the Lender,
                  including, without limitation, any failure strictly or
                  diligently to assert any right or to pursue any remedy or to
                  comply fully with applicable laws or regulations thereunder
                  which might, but for the provisions of this Section 2.4(b),
                  afford grounds for terminating, discharging or relieving such
                  Pool B Borrower, in whole or in part, from any of its
                  obligations under this Section 2.4(b), it being the intention
                  of each Pool B Borrower that, so long as any of the Pool B
                  Obligations hereunder remain unsatisfied, the obligations of
                  such Pool B Borrower under this Section 2.4(b) shall not be
                  discharged except by performance and then only to the extent
                  of such performance. The obligations of each Pool B Borrower
                  under this Section 2.4(b) shall not be diminished or rendered
                  unenforceable by any winding up, reorganization, arrangement,
                  liquidation, reconstruction or similar proceeding with respect
                  to any reconstruction or similar proceeding with respect to
                  any Pool B Borrower or any Lender. The joint and several
                  liability of the Pool B Borrowers hereunder shall continue in
                  full force and effect notwithstanding any absorption, merger,
                  amalgamation or any other change whatsoever in the name,
                  membership, constitution or place of formation of any Pool B
                  Borrower or any Lender.

                           (vi) The provisions of this Section 2.4(b) are made
                  for the benefit of the Administrative Agent and the Lenders
                  and their respective successors and assigns, and may be
                  enforced by any such Person from time to time against any of
                  the Pool B Borrowers as often as occasion therefor may arise
                  and without requirement on the part of any Lender first to
                  marshal any of its claims or to exercise any of its rights
                  against any of the other Pool B Borrowers or to exhaust any
                  remedies available to it against any of the other Pool B
                  Borrowers or to resort to any other source or means of
                  obtaining payment of any of the Pool B Obligations or to elect
                  any other remedy. The provisions of this Section 2.4(b) shall
                  remain in effect until all the Pool B Obligations hereunder
                  shall have been paid in full or otherwise fully satisfied. If
                  at any time, any payment, or any part thereof, made in respect
                  of any of the Pool B Obligations, is rescinded or must
                  otherwise be restored or returned by the Lenders upon the
                  insolvency, bankruptcy or reorganization of any of the Pool B
                  Borrowers, or otherwise, the provisions of

                  as though such payment had not been made.

                           (vii) Notwithstanding any provision to the contrary
                  contained herein or in any other of the Credit Documents or
                  Hedging Agreements of the Pool B Borrowers, the obligations of
                  each Pool B Borrower hereunder shall be limited to an
                  aggregate amount equal to the largest amount that would not
                  render its obligations hereunder subject to avoidance under

                  provisions of any applicable state law.

                           (viii) Notwithstanding anything to the contrary
                  contained in any Credit Document, each of the parties hereto
                  agrees that the Pool B Borrowers shall not have any liability
                  for the Pool A Obligations and Pool C Obligations.

                  (c)      Pool C Borrowers.

                           (i) Each of the Pool C Borrowers is accepting joint
                  and several liability hereunder for the Pool C Obligations in
                  consideration of the financial accommodation to be provided by
                  the Lenders under this Credit Agreement, for the mutual
                  benefit, directly and indirectly, of each of the Pool C
                  Borrowers and in consideration of the undertakings of each of
                  the Pool C Borrowers to accept joint and several liability for
                  the obligations of each of them.

                           (ii) Each of the Pool C Borrowers jointly and
                  severally hereby irrevocably and unconditionally accepts, not
                  merely as a surety but also as a co-debtor, joint and several
                  liability with the other Pool C Borrowers with respect to the
                  payment and performance of all of the Pool C Obligations
                  arising under this Credit Agreement and the other Credit
                  Documents, it being the intention of the parties hereto that
                  all the Pool C Obligations shall be the joint and several
                  obligations of each of the Pool C Borrowers without
                  preferences or distinction among them.

                           (iii) If and to the extent that any of the Pool C
                  Borrowers shall fail to make any payment with respect to any
                  of the Pool C Obligations hereunder as and when due or to
                  perform any of such obligations in accordance with the terms
                  thereof (including, without limitation, any applicable cure
                  periods), then in each such event, the other Pool C Borrowers
                  will make such payment with respect to, or perform, such
                  obligation.

                           (iv) The obligations of each Borrower under the
                  provisions of this Section 2.4(c) constitute full recourse
                  obligations of such Pool C Borrower, enforceable against it to

                  each Pool C Borrower hereunder shall be limited to an
                  aggregate amount equal to the largest amount that would not
                  render its obligations hereunder subject to avoidance under
                  Section 548 of the Bankruptcy Code or any comparable
                  provisions of any applicable state law.

                           (viii) Notwithstanding anything to the contrary
                  contained in any Credit Document, each of the parties hereto
                  agrees that the Pool C Borrowers shall not have any liability
                  for the Pool A Obligations and Pool B Obligations.

Agent to) upon such Borrower's request and at such Borrower's expense, such
documentation as is reasonably necessary to evidence the release of the
Administrative Agent's security interest in such Borrower's assets.

                                    SECTION 3

                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES

         3.1      DEFAULT RATE.

         Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per annum rate 2% greater than the
rate which would otherwise be applicable (or if no rate is applicable, whether
in respect of interest, fees or other amounts, then the Adjusted Base Rate plus
2%).

         3.2      EXTENSION AND CONVERSION.

         The Designated Borrowers shall have the option, on any Business Day, to
extend existing Loans into a subsequent permissible Interest Period or to
convert Loans into Loans of another interest rate type; provided, however, that
(i) except as provided in Section 3.8, Eurodollar Loans may be converted into
Base Rate Loans or extended as Eurodollar Loans for new Interest Periods

                                       39
<PAGE>   45
only on the last day of the Interest Period applicable thereto, (ii) Eurodollar
Loans may be extended, and Base Rate Loans may be converted into Eurodollar
Loans, only if the conditions precedent set forth in Section 5.2 are satisfied
on the date of extension or conversion, (iii) Loans extended as, or converted
into, Eurodollar Loans shall be subject to the terms of the definition of
"Interest Period" set forth in Section 1.1 and shall be in such minimum amounts
as provided in Section 2.1(b)(ii), (iv) no more than twelve Eurodollar Loans
(other than Eurodollar Loans outstanding which were used by the Borrowers solely
to make interest payments in accordance with the terms hereof) shall be
outstanding hereunder at any time (it being understood that, for purposes
hereof, Eurodollar Loans with different Interest Periods shall be considered as
separate Eurodollar Loans, even if they begin on the same date, although
borrowings, extensions and conversions may, in accordance with the provisions
hereof, be combined at the end of existing Interest Periods to constitute a new
Eurodollar Loan with a single Interest Period) and (v) any request for extension
or conversion of a Eurodollar Loan which shall fail to specify an Interest
Period shall be deemed to be a request for an Interest Period of one month. Each
such extension or conversion shall be effected by a Designated Borrower by
giving a Notice of Extension/Conversion (or telephonic notice promptly confirmed
in writing) to the office of the Administrative Agent specified in specified in
Schedule 2.1(a)(i), or at such other office as the Administrative Agent may
designate in writing, prior to 11:00 A.M. (Charlotte, North Carolina time) on
the Business Day of, in the case of the conversion of a Eurodollar Loan into a
Base Rate Loan, and on the third Business Day prior to, in the case of the
extension of a Eurodollar Loan as, or conversion of a Base Rate Loan into, a
Eurodollar Loan, the date of the proposed extension or conversion, specifying
the date of the proposed extension or conversion, the Loans to be so extended or
converted, the types of Loans into which such Loans are to be converted and, if
appropriate, the applicable Interest Periods with respect thereto. Each request
for extension or conversion shall be irrevocable and shall constitute a
representation and warranty by the applicable Borrowers of the matters specified
in subsections (b), (c), (d), (e), (f) and (g) of Section 5.2(i), (ii) or (iii),
as applicable. In the event a Designated Borrower fails to request extension or
conversion of any Eurodollar Loan in accordance with this Section, or any such
conversion or extension is not permitted or required by this Section, then such
Eurodollar Loan shall be automatically converted into a Base Rate Loan at the
end of the Interest Period applicable thereto. The Administrative Agent shall
give each Lender notice as promptly as practicable of any such proposed
extension or conversion affecting any Loan.

         3.3      PREPAYMENTS.

                  (a) Voluntary Prepayments. The Borrowers shall have the right
         to prepay Loans in whole or in part from time to time; provided,
         however, that each partial prepayment of Loans shall be in a minimum
         principal amount of $1,000,000 and integral multiples of $100,000.
         Subject to the foregoing terms, amounts prepaid under this Section
         3.3(a) shall be applied as the Borrowers may elect; provided that if
         the Borrowers fail to specify a voluntary prepayment then such
         prepayment shall be applied to Revolving Loans, in each case first to
         Base Rate Loans and then to Eurodollar Loans in direct order of
         Interest Period maturities. All prepayments under this Section 3.3(a)
         shall be subject to Section 3.12, but otherwise without premium or
         penalty.

                                       40

<PAGE>   46

                  (b)      Mandatory Prepayments.

                           (i) Revolving Committed Amount. If at any time, the
                  sum of the aggregate principal amount of Revolving Loans
                  outstanding shall exceed the lesser of (x) the Revolving
                  Committed Amount and (y) the Borrowing Base, the Borrowers
                  shall immediately make payment on the Loans in an amount
                  sufficient to eliminate the deficiency.

                           (ii) Disposition or Refinancing of Eligible
                  Project/Disposition of Capital Stock.

                           (A) Immediately upon the disposition or refinancing
                  of a Facility, such Borrower shall prepay the Revolving Loans
                  in an aggregate amount equal to the amount of the Revolving
                  Loans of such Borrower borrowed hereunder with respect to such
                  Facility (such prepayment to be applied as set forth in clause
                  (iii) below).

                           (B) Immediately upon the disposition of the Capital
                  Stock of a Borrower in accordance with Section 8.5, such
                  Borrower shall prepay the Revolving Loans in an aggregate
                  amount equal to the amount of the Revolving Loans of such
                  Borrower borrowed hereunder (such prepayment to be applied as
                  set forth in clause (iii) below).

                           (C) If a Facility which has been constructed by a
                  Borrower using proceeds of the Revolving Loans is not fully
                  constructed and open for business within fifteen months of the
                  commencement of construction of such Facility, such Borrower
                  shall immediately prepay the Revolving Loans in an aggregate
                  amount equal to the amount of Revolving Loans borrowed
                  hereunder with respect to such Facility (such prepayment to be
                  applied as set forth in clause (iii) below.

                           (iii) Application of Mandatory Prepayments. All
                  amounts required to be paid pursuant to Section 3.3(b)(i) and
                  (ii) shall be applied to Revolving Loans. Within the
                  parameters of the applications set forth above, prepayments
                  shall be applied first to Base Rate Loans and then to
                  Eurodollar Loans in direct order of Interest Period
                  maturities. All prepayments under this Section 3.3(b) shall be
                  subject to Section 3.12.

         3.4      TERMINATION AND REDUCTION OF REVOLVING COMMITTED AMOUNT.

                  Revolving Commitment. The Borrowers may from time to time
         permanently reduce or terminate the Revolving Committed Amount in whole
         or in part (in minimum aggregate amounts of $5,000,000 or in integral
         multiples of $5,000,000 in excess thereof (or, if less, the full
         remaining amount of the then applicable Revolving Committed Amount))
         upon five Business Days' prior written notice to the Administrative
         Agent; provided, that, no such termination or reduction shall be made
         which would cause the sum of the aggregate outstanding principal amount
         of the Revolving Loans to exceed the Revolving Committed Amount,
         unless, concurrently with such termination or reduction, the
                                       41

<PAGE>   47

         Loans are repaid to the extent necessary to eliminate such excess. The
         Administrative Agent shall promptly notify each affected Lender of
         receipt by the Administrative Agent of any notice from the Borrowers
         pursuant to this Section 3.4.

         3.5      FEES.

                  (a) Upfront Fees. The Borrowers agree to pay to the
         Administrative Agent for the benefit of the Lenders in immediately
         available funds on or before the Closing Date an upfront fee (the
         "Upfront Fee") in the amount provided in the Administrative Agent's Fee
         Letter.

                  (b) Unused Fee. In consideration of the Revolving Commitments
         of the Lenders hereunder, the Borrowers agree to pay to the
         Administrative Agent for the account of each Lender a fee (the "Unused
         Fee") on the Unused Revolving Committed Amount computed at a per annum
         rate for each day during the applicable Unused Fee Calculation Period
         (hereinafter defined) equal to the Applicable Percentage for Unused Fee
         in effect from time to time. The Unused Fee shall commence to accrue on
         the Closing Date and shall be due and payable in arrears on the last
         business day of each March, June, September and December (and any date
         that the Revolving Committed Amount is reduced as provided in Section
         3.4 and the Maturity Date) for the immediately preceding quarter (or
         portion thereof) (each such quarter or portion thereof for which the
         Unused Fee is payable hereunder being herein referred to as an "Unused
         Fee Calculation Period"), beginning with the first of such dates to
         occur after the Closing Date.

                  (c) Administrative Fees. The Borrowers agree to pay to the
         Administrative Agent, for its own account and Banc of America
         Securities LLC, as applicable, the fees referred to in the
         Administrative Agent's Fee Letter (collectively, the "Administrative
         Agent's Fees").

         3.6      CAPITAL ADEQUACY.

         If any Lender has determined, after the date hereof, that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy), then,
upon notice from such Lender to the Borrowers (which notice shall set forth such
change regarding capital adequacy and the calculation of such reduced rate of
return as a result thereof), the Borrowers shall be obligated to pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction; provided, however, that no such amounts shall be payable with respect
to a reduction in rate of return incurred more than 180 days before such Lender
demands compensation under this Section 3.6. Each

                                       42

<PAGE>   48
determination by any such Lender of amounts owing under this Section shall,
absent manifest or demonstrable error, be conclusive and binding on the parties
hereto. The Lenders agree that in the exercise of rights under this Section 3.6,
they will accord the Borrowers the treatment generally accorded by the Lenders
to similarly situated borrowers.

         3.7      LIMITATION ON EURODOLLAR LOANS.

         If on or prior to the first day of any Interest Period for any
Eurodollar Loan:

                  (a) the Administrative Agent determines (which determination
         shall be conclusive) that by reason of circumstances affecting the
         relevant market, adequate and reasonable means do not exist for
         ascertaining the Eurodollar Rate for such Interest Period; or

                  (b) the Required Lenders determine (which determination shall
         be conclusive) and notify the Administrative Agent that the Eurodollar
         Rate will not adequately and fairly reflect the cost to the Lenders of
         funding Eurodollar Loans for such Interest Period;

then the Administrative Agent shall give the Borrowers prompt notice thereof,
and so long as such condition remains in effect, the Lenders shall be under no
obligation to make additional Eurodollar Loans, continue Eurodollar Loans, or to
convert Base Rate Loans into Eurodollar Loans and the Borrowers shall, on the
last day(s) of the then current Interest Period(s) for the outstanding
Eurodollar Loans, either prepay such Eurodollar Loans or convert such Eurodollar
Loans into Base Rate Loans in accordance with the terms of this Credit
Agreement.

         3.8      ILLEGALITY.

         Notwithstanding any other provision herein, if the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
occurring after the Closing Date shall make it unlawful for any Lender to make
or maintain Eurodollar Loans as contemplated by this Credit Agreement, (a) such
Lender shall promptly give written notice of such circumstances to the Borrowers
and the Administrative Agent (which notice shall be withdrawn whenever such
circumstances no longer exist), (b) the commitment of such Lender hereunder to
make Eurodollar Loans, continue Eurodollar Loans as such and convert a Base Rate
Loan to Eurodollar Loans, shall forthwith be canceled and, until such time as it
shall no longer be unlawful for such Lender to make or maintain Eurodollar
Loans, such Lender shall then have a commitment only to make a Base Rate Loan
when a Eurodollar Loan is requested and (c) on receipt of such notice by the
Administrative Agent and the Borrowers, such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on
the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrowers shall pay to
such Lender such amounts, if any, as may be required pursuant to Section 3.12.

                                       43

<PAGE>   49

         3.9      REQUIREMENTS OF LAW.

         If, after the date hereof, the adoption of any applicable law, rule, or
regulation, or any change in any applicable law, rule, or regulation, or any
change in the interpretation or administration thereof by any Governmental
Authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such Governmental Authority, central bank, or comparable agency:

                        (i) shall subject such Lender (or its Applicable Lending
         Office) to any tax, duty, or other charge with respect to any
         Eurodollar Loans, its Notes, or its obligation to make Eurodollar
         Loans, or change the basis of taxation of any amounts payable to such
         Lender (or its Applicable Lending Office) under this Credit Agreement
         or its Notes in respect of any Eurodollar Loans (other than taxes
         imposed on the overall net income of such Lender by the jurisdiction in
         which such Lender has its principal office or such Applicable Lending
         Office);

                       (ii) shall impose, modify, or deem applicable any
         reserve, special deposit, assessment, or similar requirement (other
         than the Eurodollar Reserve Requirement utilized in the determination
         of the Adjusted Eurodollar Rate) relating to any extensions of credit
         or other assets of, or any deposits with or other liabilities or
         commitments of, such Lender (or its Applicable Lending Office),
         including the Commitment of such Lender hereunder; or

                      (iii) shall impose on such Lender (or its Applicable
         Lending Office) or the London interbank market any other condition
         affecting this Credit Agreement or its Notes or any of such extensions
         of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, converting into, continuing, or
maintaining any Eurodollar Loans or to reduce any sum received or receivable by
such Lender (or its Applicable Lending Office) under this Credit Agreement or
its Notes with respect to any Eurodollar Loans, then the Borrowers shall pay to
such Lender on demand such amount or amounts as will compensate such Lender for
such increased cost or reduction. If any Lender requests compensation by the
Borrowers under this Section 3.9, the Borrowers may, by notice to such Lender
(with a copy to the Administrative Agent), suspend the obligation of such Lender
to make or continue Eurodollar Loans, or to convert Base Rate Loans into
Eurodollar Loans, until the event or condition giving rise to such request
ceases to be in effect (in which case the provisions of Section 3.10 shall be
applicable); provided that such suspension shall not affect the right of such
Lender to receive the compensation so requested. Each Lender shall promptly
notify the Borrowers and the Administrative Agent of any event of which it has
knowledge, occurring after the date hereof, which will entitle such Lender to
compensation pursuant to this Section 3.9 and will designate a different
Applicable Lending Office if such designation will avoid the need for, or reduce
the amount of, such compensation and will not, in the judgment of such Lender,
be otherwise disadvantageous to it. Any Lender claiming compensation under this
Section 3.9 shall furnish to the Borrowers and the Administrative Agent a
statement setting forth in reasonable detail the additional amount or amounts to
be paid to it

                                       44

<PAGE>   50
hereunder which shall be conclusive in the absence of manifest or demonstrable
error. In determining such amount, such Lender may use any reasonable averaging
and attribution methods. No Lender shall be entitled to receive any compensation
for such amounts incurred more than 180 days prior to the delivery of such
statement. If any Credit Party is required to pay compensation to any Lender
pursuant to this Section 3.9, then such Lender will agree to use reasonable
efforts to change the jurisdiction of its Applicable Lending Office so as to
eliminate or reduce any such additional compensation which may thereafter accrue
if such change in the judgment of the Lender, is not otherwise disadvantageous
to such Lender. The Lenders agree that in the exercise of rights under this
Section 3.9, they will accord the Borrowers the treatment generally accorded by
the Lenders to similarly situated borrowers.

         3.10     TREATMENT OF AFFECTED LOANS.

         If the obligation of any Lender to make any Eurodollar Loan or to
continue, or to convert Base Rate Loans into, Eurodollar Loans shall be
suspended pursuant to Section 3.8 or 3.9 hereof, such Lender's Eurodollar Loans
shall be automatically converted into Base Rate Loans on the last day(s) of the
then current Interest Period(s) for such Eurodollar Loans (or, in the case of a
conversion required by Section 3.8 hereof, on such earlier date as such Lender
may specify to the Borrowers with a copy to the Administrative Agent) and,
unless and until such Lender gives notice as provided below that the
circumstances specified in Section 3.8 or 3.9 hereof that gave rise to such
conversion no longer exist:

                  (a) to the extent that such Lender's Eurodollar Loans have
         been so converted, all payments and prepayments of principal that would
         otherwise be applied to such Lender's Eurodollar Loans shall be applied
         instead to its Base Rate Loans; and

                  (b) all Loans that would otherwise be made or continued by
         such Lender as Eurodollar Loans shall be made or continued instead as
         Base Rate Loans, and all Base Rate Loans of such Lender that would
         otherwise be converted into Eurodollar Loans shall remain as Base Rate
         Loans.

If such Lender gives notice to the Borrowers (with a copy to the Administrative
Agent) that the circumstances specified in Section 3.8 or 3.9 hereof that gave
rise to the conversion of such Lender's Eurodollar Loans pursuant to this
Section 3.10 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans made by other
Lenders are outstanding, such Lender's Base Rate Loans shall be automatically
converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Eurodollar Loans, to the extent necessary so that, after giving
effect thereto, all Loans held by the Lenders holding Eurodollar Loans and by
such Lender are held pro rata (as to principal amounts, interest rate basis, and
Interest Periods) in accordance with their respective Commitments.

         3.11     TAXES.

                  (a) Any and all payments by any Credit Party to or for the
         account of any Lender or the Administrative Agent hereunder or under
         any other Credit Document shall be made free and clear of and without
         deduction for any and all present or future taxes, duties,

                                       45

<PAGE>   51
         levies, imposts, deductions, charges or withholdings, and all
         liabilities with respect thereto, excluding, in the case of each Lender
         and the Administrative Agent, taxes imposed on its income, and
         franchise taxes imposed on it, by the jurisdiction under the laws of
         which such Lender (or its Applicable Lending Office) or the
         Administrative Agent (as the case may be) is organized or any political
         subdivision thereof (all such non-excluded taxes, duties, levies,
         imposts, deductions, charges, withholdings, and liabilities being
         hereinafter referred to as "Taxes"). If any Credit Party shall be
         required by law to deduct any Taxes from or in respect of any sum
         payable under this Credit Agreement or any other Credit Document to any
         Lender or the Administrative Agent, (i) the sum payable shall be
         increased as necessary so that after making all required deductions
         (including deductions applicable to additional sums payable under this
         Section 3.11) such Lender or the Administrative Agent receives an
         amount equal to the sum it would have received had no such deductions
         been made, (ii) such Credit Party shall make such deductions, (iii)
         such Credit Party shall pay the full amount deducted to the relevant
         taxation authority or other authority in accordance with applicable
         law, and (iv) such Credit Party shall furnish to the Administrative
         Agent, at its address referred to in Section 11.1, the original or a
         certified copy of a receipt evidencing payment thereof.

                  (b) In addition, the Borrowers agree to pay any and all
         present or future stamp or documentary taxes and any other excise or
         property taxes or charges or similar levies which arise from any
         payment made under this Credit Agreement or any other Credit Document
         or from the execution or delivery of, or otherwise with respect to,
         this Credit Agreement or any other Credit Document (hereinafter
         referred to as "Other Taxes").

                  (c) The Borrowers agree to indemnify each Lender and the
         Administrative Agent for the full amount of Taxes and Other Taxes
         (including, without limitation, any Taxes or Other Taxes imposed or
         asserted by any jurisdiction on amounts payable under this Section
         3.11) paid by such Lender or the Administrative Agent (as the case may
         be) and any liability (including penalties, interest, and expenses)
         arising therefrom or with respect thereto.

                  (d) Each Lender that is not a United States person under
         Section 7701(a)(30) of the Code, on or prior to the date of its
         execution and delivery of this Credit Agreement in the case of each
         Lender listed on the signature pages hereof and on or prior to the date
         on which it becomes a Lender in the case of each other Lender, and from
         time to time thereafter if requested in writing by the Borrowers or the
         Administrative Agent (but only so long as such Lender remains lawfully
         able to do so), shall provide the Borrowers and the Administrative
         Agent with (i) Internal Revenue Service Form 1001 or 4224, as
         appropriate, or any successor form prescribed by the Internal Revenue
         Service, certifying that such Lender is entitled to benefits under an
         income tax treaty to which the United States is a party which reduces
         the rate of withholding tax on payments of interest or certifying that
         the income receivable pursuant to this Credit Agreement is effectively
         connected with the conduct of a trade or business in the United States,
         (ii) Internal Revenue Service Form W-8 or W-9, as appropriate, or any
         successor form prescribed by the Internal Revenue Service, and (iii)
         any other form or certificate required by any taxing authority
         (including any certificate required by Sections 871(h) and 881(c) of
         the Internal Revenue Code), certifying

                                       46

<PAGE>   52
         that such Lender is entitled to an exemption from or a reduced rate of
         tax on payments pursuant to this Credit Agreement or any of the other
         Credit Documents.

                  (e) For any period with respect to which a Lender has failed
         to provide the Borrowers and the Administrative Agent with the
         appropriate form pursuant to Section 3.11(d) (unless such failure is
         due to a change in treaty, law, or regulation occurring subsequent to
         the date on which a form originally was required to be provided), such
         Lender shall not be entitled to indemnification under Section 3.11(a)
         or 3.11(b) with respect to Taxes imposed by the United States;
         provided, however, that should a Lender, which is otherwise exempt from
         or subject to a reduced rate of withholding tax, become subject to
         Taxes because of its failure to deliver a form required hereunder, the
         Borrowers shall take such steps as such Lender shall reasonably request
         to assist such Lender to recover such Taxes.

                  (f) If any Credit Party is required to pay additional amounts
         to or for the account of any Lender pursuant to this Section 3.11, then
         such Lender will agree to use reasonable efforts to change the
         jurisdiction of its Applicable Lending Office so as to eliminate or
         reduce any such additional payment which may thereafter accrue if such
         change, in the judgment of such Lender, is not otherwise
         disadvantageous to such Lender.

                  (g) Within thirty (30) days after the date of any payment of
         Taxes, the applicable Credit Party shall furnish to the Administrative
         Agent the original or a certified copy of a receipt evidencing such
         payment.

                  (h) Without prejudice to the survival of any other agreement
         of the Credit Parties hereunder, the agreements and obligations of the
         Credit Parties contained in this Section 3.11 shall survive the
         repayment of the Loans and other obligations under the Credit Documents
         and the termination of the Commitments hereunder.

         3.12     COMPENSATION.

         Upon the request of any Lender, the Borrowers shall pay to such Lender
such amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense incurred by it as a
result of:

                  (a) any payment, prepayment, or conversion of a Eurodollar
         Loan for any reason (including, without limitation, the acceleration of
         the Loans pursuant to Section 9.2) on a date other than the last day of
         the Interest Period for such Loan; or

                  (b) any failure by the Borrowers for any reason (including,
         without limitation, the failure of any condition precedent specified in
         Section 5 to be satisfied) to borrow, convert, continue, or prepay a
         Eurodollar Loan on the date for such borrowing, conversion,
         continuation, or prepayment specified in the relevant notice of
         borrowing, prepayment, continuation, or conversion under this Credit
         Agreement.

                                       47

<PAGE>   53

With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of the applicable Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Eurodollar Loans provided for herein (excluding,
however, the Applicable Percentage included therein, if any) over (b) the amount
of interest (as reasonably determined by such Lender) which would have accrued
to such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market. The covenants of
the Borrowers set forth in this Section 3.12 shall survive the repayment of the
Loans and other obligations under the Credit Documents and the termination of
the Commitments hereunder.

         3.13     PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

                  (a) Loans. Each Loan, each payment or (subject to the terms of
         Section 3.3) prepayment of principal of any Loan, each payment of
         interest on the Loans, each payment of Unused Fees, each reduction in
         Commitments and each conversion or extension of any Loan, shall be
         allocated pro rata among the Lenders in accordance with the respective
         principal amounts of their outstanding Revolving Loans and
         Participation Interests.

                  (b) Advances. No Lender shall be responsible for the failure
         or delay by any other Lender in its obligation to make its ratable
         share of a borrowing hereunder; provided, however, that the failure of
         any Lender to fulfill its obligations hereunder shall not relieve any
         other Lender of its obligations hereunder. Unless the Administrative
         Agent shall have been notified in writing by any Lender prior to the
         date of any requested borrowing that such Lender does not intend to
         make available to the Administrative Agent its ratable share of such
         borrowing to be made on such date, the Administrative Agent may assume
         that such Lender has made such amount available to the Administrative
         Agent on the date of such borrowing, and the Administrative Agent in
         reliance upon such assumption, may (in its sole discretion but without
         any obligation to do so) make available to the Borrowers a
         corresponding amount. If such corresponding amount is not in fact made
         available to the Administrative Agent, the Administrative Agent shall
         be able to recover such corresponding amount from such Lender. If such
         Lender does not pay such corresponding amount forthwith upon the
         Administrative Agent's demand therefor, the Administrative Agent will
         promptly notify the Borrowers, and the Borrowers shall immediately pay
         such corresponding amount to the Administrative Agent. The
         Administrative Agent shall also be entitled to recover from the Lender
         or the Borrowers, as the case may be, interest on such corresponding
         amount in respect of each day from the date such corresponding amount
         was made available by the Administrative Agent to the Borrowers to the
         date such corresponding amount is recovered by the Administrative Agent
         at a per annum rate equal to (i) from the Borrowers at the applicable
         rate for the applicable borrowing pursuant to the Notice of Borrowing
         and (ii) from a Lender at the Federal Funds Rate.

         3.14     SHARING OF PAYMENTS.

         The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan or any other obligation owing to
such Lender under this Credit Agreement through the exercise of a right of
setoff, banker's lien or counterclaim, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, or by
any other means, in excess of its pro rata share of such payment as provided for
in this Credit Agreement, such Lender shall promptly purchase from the other
Lenders a Participation Interest in such Loans and other obligations in such
amounts, and make such other adjustments from time to time, as shall be
equitable to the end that all Lenders share such payment in accordance with
their respective ratable shares as provided for in this Credit Agreement. The
Lenders further agree among themselves that if payment to a Lender obtained by
such Lender through the exercise of a right of setoff, banker's lien,
counterclaim or other event as aforesaid shall be rescinded or must otherwise be
restored, each Lender which shall have shared the benefit of such payment shall,
by repurchase of a Participation Interest theretofore sold, return its share of
that benefit (together with its share of any accrued interest payable with
respect thereto) to each Lender whose payment shall have been rescinded or
otherwise restored. The Borrowers agree that any Lender so purchasing such a
Participation Interest may, to the fullest extent permitted by law, exercise all
rights of payment, including setoff, banker's lien or counterclaim, with respect
to such Participation Interest as fully as if such Lender were a holder of such
Loan or other obligation in the amount of such Participation Interest. Except as
otherwise expressly provided in this Credit Agreement, if any Lender or the
Administrative Agent shall fail to remit to the Administrative Agent or any
other Lender an amount payable by such Lender or the Administrative Agent to the
Administrative Agent or such other Lender pursuant to this Credit Agreement on
the date when such amount is due, such payments shall be made together with
interest thereon for each date from the date such amount is due until the date
such amount is paid to the Administrative Agent or such other Lender at a rate
per annum equal to the Federal Funds Rate. If under any applicable bankruptcy,
insolvency or other similar law, any Lender receives a secured claim in lieu of
a setoff to which this Section 3.14 applies, such Lender shall, to the extent
practicable, exercise its rights in respect of such secured claim in a manner
consistent with the rights of the Lenders under this Section 3.14 to share in
the benefits of any recovery on such secured claim.

         3.15     PAYMENTS, COMPUTATIONS, ETC.

                  (a) Except as otherwise specifically provided herein, all
         payments hereunder shall be made to the Administrative Agent in dollars
         in immediately available funds, without setoff, deduction, counterclaim
         or withholding of any kind, at the Administrative Agent's office
         specified in Schedule 2.1(a)(i) not later than 1:00 P.M. (Charlotte,
         North Carolina time) on the date when due. Payments received after such
         time shall be deemed to have been received on the next succeeding
         Business Day. The Administrative Agent may (but shall not be obligated
         to) debit the amount of any such payment which is not made by such time
         to any ordinary deposit account of any of the Borrowers or any other
         Operative Party maintained with the Administrative Agent (with notice
         to the Borrowers or such other Operative Party). The Borrowers (or any
         one of them) shall, at the time it makes any

                                       49

<PAGE>   55

         payment under this Credit Agreement, specify to the Administrative
         Agent the Loans, Fees, interest or other amounts payable by the
         Borrowers hereunder to which such payment is to be applied (and in the
         event that it fails so to specify, or if such application would be
         inconsistent with the terms hereof, the Administrative Agent shall
         distribute such payment to the Lenders in such manner as the
         Administrative Agent may determine to be appropriate in respect of
         obligations owing by the Borrowers hereunder, subject to the terms of
         Section 3.13(a)). The Administrative Agent will distribute such
         payments to such Lenders, if any such payment is received prior to 1:00
         P.M. (Charlotte, North Carolina time) on a Business Day in like funds
         as received prior to the end of such Business Day and otherwise the
         Administrative Agent will distribute such payment to such Lenders on
         the next succeeding Business Day. If the Administrative Agent fails to
         distribute such payment on the next succeeding Business Day, then the
         amount of such payment shall bear interest payable to the Lenders at a
         rate equal to the Federal Funds Rate. Whenever any payment hereunder
         shall be stated to be due on a day which is not a Business Day, the due
         date thereof shall be extended to the next succeeding Business Day
         (subject to accrual of interest and Fees for the period of such
         extension), except that in the case of Eurodollar Loans, if the
         extension would cause the payment to be made in the next following
         calendar month, then such payment shall instead be made on the next
         preceding Business Day. Unless the Administrative Agent receives notice
         from a Borrower prior to the date on which any payment is due to the
         Lenders that such Borrower will not make such payment in full as and
         when required, the Administrative Agent may assume that such Borrower
         has made such payment in full to the Administrative Agent on such date
         in immediately available funds and the Administrative Agent may (but
         shall not be so required), in reliance upon such assumption, distribute
         to each Lender on such date an amount equal to the amount then due such
         Lender. If and to the extent such Borrower has not made such payment in
         full to the Administrative Agent, each Lender shall repay to the
         Administrative Agent on demand such amount distributed to such Lender,
         together with interest thereon at the Federal Funds Rate for each day
         from the date such amount is distributed to such lender until the date
         repaid. Except as expressly provided otherwise herein, all computations
         of interest and fees shall be made on the basis of actual number of
         days elapsed over a year of 360 days, except with respect to
         computation of interest on Base Rate Loans which (unless the Base Rate
         is determined by reference to the Federal Funds Rate) shall be
         calculated based on a year of 365 or 366 days, as appropriate. Interest
         shall accrue from and include the date of borrowing, but exclude the
         date of payment.

                  (b)      Allocation of Payments After Event of Default.

                           (i) Fees and Expenses. Notwithstanding any other
                  provisions of this Credit Agreement to the contrary, after the
                  occurrence and during the continuance of an Event of Default,
                  all amounts collected or received by the Administrative Agent
                  or any Lender on account of the Credit Party Obligations or
                  any other amounts outstanding under any of the Credit
                  Documents or in respect of the Collateral shall be paid over
                  or delivered as follows:

                           FIRST, to the payment of all reasonable out-of-pocket
                  costs and expenses (including without limitation reasonable
                  attorneys' fees) of the Administrative Agent

                                       50

<PAGE>   56

                  then due and owing in connection with enforcing the rights of
                  the Lenders under the Credit Documents and any protective
                  advances made by the Administrative Agent with respect to the
                  Collateral under or pursuant to the terms of the Collateral
                  Documents;

                           SECOND, to payment of any fees then due and owing to
                  the Administrative Agent;

                           THIRD, to the payment of all reasonable out-of-pocket
                  costs and expenses (including without limitation, reasonable
                  attorneys' fees) of each of the Lenders then due and owing in
                  connection with enforcing its rights under the Credit
                  Documents or otherwise with respect to the Credit Party
                  Obligations owing to such Lender;

                  In carrying out the foregoing, (A) amounts received shall be
                  applied in the numerical order provided until exhausted prior
                  to application to the next succeeding category; and (B) each
                  of the Lenders shall receive an amount equal to its pro rata
                  share (based on the proportion that the then outstanding Loans
                  held by such Lender bears to the aggregate then outstanding
                  Loans) of amounts available to be applied pursuant to clause
                  "THIRD" above.

                           (ii) Pool A Obligations. Notwithstanding any other
                  provisions of this Credit Agreement to the contrary, after (A)
                  the occurrence and during the continuance of an Event of
                  Default and (B) all fees, costs and expenses identified in
                  Section 3.15(b)(i) have been paid in full, all amounts
                  collected or received by the Administrative Agent or any
                  Lender on account of the Pool A Obligations or any other
                  amounts owing from a Pool A Borrower outstanding under any of
                  the Credit Documents or in respect of the Pool A Collateral
                  shall be paid over or delivered as follows:

                           FIRST,  to the payment of all of the Pool A
                  Obligations consisting of accrued fees and interest;

                           SECOND, to the payment of the outstanding principal
                  amount of the Pool A Obligations;

                           THIRD , to all other Pool A Obligations and other
                  obligations of the Pool A Borrowers which shall have become
                  due and payable under the Credit Documents or otherwise and
                  not repaid pursuant to clauses "FIRST" through "THIRD" above;
                  and

                           FOURTH, to the payment of the surplus, if any, to
                  whoever may be lawfully entitled to receive such surplus.

                  In carrying out the foregoing, (x) amounts received shall be
                  applied in the numerical order provided until exhausted prior
                  to application to the next succeeding category; and (y) each

<PAGE>   59
         and interest payable and paid to such Lender from time to time under
         this Credit Agreement. Each Lender will make reasonable efforts to
         maintain the accuracy of its account or accounts and to promptly update
         its account or accounts from time to time, as necessary.

                  (b) The Administrative Agent shall maintain the Register
         pursuant to Section 11.3(c), and a subaccount for each Lender, in which
         Register and subaccounts (taken together) shall be recorded (i) the
         amount, type and Interest Period of each such Loan hereunder, (ii) the
         amount of any principal or interest due and payable or to become due
         and payable to each Lender hereunder and (iii) the amount of any sum

                  (c) The entries made in the accounts, Register and subaccounts
         maintained pursuant to subsection (b) of this Section 3.16 (and, if
         consistent with the entries of the Administrative Agent, subsection (a)
         shall be prima facie evidence of the existence and amounts of the
         obligations of the Credit Parties therein recorded; provided, however,
         that the failure of any Lender or the Administrative Agent to maintain
         any such account, such Register or such subaccount, as applicable, or
         any error therein, shall not in any manner affect the obligation of the
         Credit Parties to repay the Credit Party Obligations owing to such
         Lender.

         3.17     SUBSTITUTION OF LENDERS.

         Upon the receipt by the Borrowers from any Lender (an "Affected
Lender") of a claim for compensation under Section 3.9 or Section 3.11, or in
the event any Lender whose obligations to make Eurodollar Loans have been
suspended under Section 3.8, the Borrowers may: (i) request the Affected Lender
to use its reasonable efforts to obtain a replacement bank or financial
institution satisfactory to the Borrowers to acquire and assume all or a ratable
part of all of such Affected Lender's Revolving Loans and Revolving Commitment
(a "Replacement Lender"); (ii) request one more of the other Lenders to acquire
and assume all or part of such Affected Lender's Revolving Loans and Revolving
Commitment; or (iii) designate an Eligible Assignee that is willing to become

                                    SECTION 4

                                    GUARANTY

         4.1      THE PARENT GUARANTY.

         The Parent hereby guarantees to each Lender, each Affiliate of a Lender
that enters into a Hedging Agreement with any Operative Party, and the
Administrative Agent as hereinafter provided, as primary obligor and not as
surety, (a) the prompt payment of the Credit Party Obligations in full when due
(whether at stated maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise) strictly in accordance with the
terms thereof and (b) the timely performance of all other obligations of the
Borrowers under the Credit Documents, including, without limitation, that the
Eligible Projects will be constructed in accordance with this Credit Agreement
and applicable law. The Parent hereby further agrees that if any of the Credit
Party Obligations are not paid in full when due (whether at stated maturity, as
a mandatory prepayment, by acceleration, as a mandatory cash collateralization
or otherwise), the Parent will promptly pay the same, without any demand or
notice whatsoever, and that in the case of any extension of time of payment or
renewal of any of the Credit Party Obligations, the same will be promptly paid
in full when due (whether at extended maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) in accordance
with the terms of such extension or renewal. The Parent further agrees to (x)
assume all responsibility for the completion of the Eligible Projects and, at
the Parent's own cost and expense, to cause the Eligible Projects to be fully
completed in accordance with the plans and specifications provided to the
Administrative Agent in accordance with the terms hereof and in accordance with
this Credit Agreement, (y) pay all bills in connection with the construction of
the Eligible Projects and (z) indemnify and hold the Lenders harmless from any
and all loss, cost, liability or expense the Lenders may suffer by reason of any
such event (except if such event is due to the gross negligence or willful
misconduct of the Administrative Agent or the Lenders).

         Notwithstanding any provision to the contrary contained herein or in
any other of the Credit Documents or Hedging Agreements of any Operative Party,
the obligations of the Parent hereunder shall be limited to an aggregate amount
equal to the largest amount that would not render its obligations hereunder
subject to avoidance under Section 548 of the Bankruptcy Code or any comparable
provisions of any applicable state law.

         4.2      OBLIGATIONS UNCONDITIONAL.

         The obligations of the Parent under Section 4.1 are joint and several,
absolute and unconditional, irrespective of the value, genuineness, validity,
regularity or enforceability of any of the Credit Documents or Hedging
Agreements of any Operative Party, or any other agreement or instrument referred
to therein, or any substitution, release, impairment or exchange of any other
guarantee of or security for any of the Credit Party Obligations, and, to the
fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever which might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor, it being the intent of this
Section 4.2 that the obligations of the Parent hereunder shall be absolute and
unconditional under any and all circumstances. The Parent agrees that it shall
have no right of subrogation, indemnity,

                                       55

<PAGE>   61
reimbursement or contribution against a Borrower or any other Guarantor for
amounts paid under this Section 4 until such time as the Lenders (and any
Affiliates of Lenders entering into Hedging Agreements with any Operative Party)
have been paid in full (other than contingent indemnification obligations which
survive), all Commitments under this Credit Agreement have been terminated and
no Person or Governmental Authority shall have any right to request any return
or reimbursement of funds from the Lenders in connection with monies received
under the Credit Documents or Hedging Agreements with any Operative Party.
Without limiting the generality of the foregoing, it is agreed that, to the
fullest extent permitted by law, the occurrence of any one or more of the
following shall not alter or impair the liability of the Parent hereunder which
shall remain absolute and unconditional as described above:

                  (a) at any time or from time to time, without notice to any
         Guarantor, the time for any performance of or compliance with any of
         the Credit Party Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (b) any of the acts mentioned in any of the provisions of any
         of the Credit Documents, any Hedging Agreement with any Operative Party
         or any other agreement or instrument referred to in the Credit
         Documents or such Hedging Agreements shall be done or omitted;

                  (c) the maturity of any of the Credit Party Obligations shall
         be accelerated, or any of the Credit Party Obligations shall be
         modified, supplemented or amended in any respect, or any right under
         any of the Credit Documents, any Hedging Agreement with any Operative
         Party or any other agreement or instrument referred to in the Credit
         Documents or such Hedging Agreements shall be waived or any other
         guarantee of any of the Credit Party Obligations or any security
         therefor shall be released, impaired or exchanged in whole or in part
         or otherwise dealt with;

                  (d) any Lien granted to, or in favor of, the Administrative
         Agent or any Lender or Lenders as security for any of the Credit Party
         Obligations shall fail to attach or be perfected; or

                  (e) any of the Credit Party Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of any Guarantor) or shall be subordinated to the claims
         of any Person (including, without limitation, any creditor of any
         Guarantor).

With respect to its obligations hereunder, the Parent hereby expressly waives
diligence, presentment, demand of payment, protest and all notices whatsoever,
and any requirement that the Administrative Agent or any Lender exhaust any
right, power or remedy or proceed against any Person under any of the Credit
Documents, any Hedging Agreement with any Operative Party or any other agreement
or instrument referred to in the Credit Documents or such Hedging Agreements, or
against any other Person under any other guarantee of, or security for, any of
the Credit Party Obligations.

<PAGE>   62

         4.3      REINSTATEMENT.

         The obligations of the Parent under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Credit Party Obligations is
rescinded or must be otherwise restored by any holder of any of the Credit Party
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and the Parent agrees that it will indemnify the
Administrative Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, fees and expenses of counsel) incurred
by the Administrative Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

         4.4      CERTAIN ADDITIONAL WAIVERS.

         The Parent agrees that it shall have no right of recourse to security
for the Credit Party Obligations, except through the exercise of rights of
subrogation in accordance with Section 4.2.

         4.5      REMEDIES.

         The Parent agrees that, to the fullest extent permitted by law, the
Credit Party Obligations may be declared to be forthwith due and payable as
provided in Section 9.2 (and shall be deemed to have become automatically due
and payable in the circumstances provided in said Section 9.2) for purposes of
Section 4.1 notwithstanding any stay, injunction or other prohibition preventing
such declaration (or preventing the Credit Party Obligations from becoming
automatically due and payable) as against any other Person and that, in the
event of such declaration (or the Credit Party Obligations being deemed to have
become automatically due and payable), the Credit Party Obligations (whether or
not due and payable by any other Person) shall forthwith become due and payable
by the Parent for purposes of Section 4.1. The Parent acknowledges and agrees
that its obligations hereunder are secured in accordance with the terms of the
Pledge Agreement and the other Collateral Documents and that the Administrative
Agent and Lenders may exercise their remedies thereunder in accordance with the
terms thereof.

         4.6      GUARANTEE OF PAYMENT; CONTINUING GUARANTEE.

         The guarantee of the Parent in this Section 4 is a guaranty of payment
and not of collection, is a continuing guarantee, and shall apply to all Credit
Party Obligations whenever arising.

         6.11     ERISA.

                  (a) During the five-year period prior to the date on which
         this representation is made or deemed made: (i) no ERISA Event has
         occurred, and, to the best knowledge of such Operative Party, no event
         or condition has occurred or exists as a result of which any ERISA
         Event could reasonably be expected to occur, with respect to any Plan;
         (ii) no "accumulated funding deficiency," as such term is defined in
         Section 302 of ERISA and Section 412 of the Code, whether or not
         waived, has occurred with respect to any Plan; (iii) each Plan has been
         maintained, operated, and funded in compliance with its own terms and
         in material compliance with the provisions of ERISA, the Code, and any
         other applicable federal or state laws; and (iv) no lien in favor of
         the PBGC or a Plan has arisen or is reasonably likely to arise on
         account of any Plan.

                  (b) The actuarial present value of all "benefit liabilities"
         (as defined in Section 4001(a)(16) of ERISA), whether or not vested,
         under each Single Employer Plan, as of the last annual valuation date
         prior to the date on which this representation is made or deemed made
         (determined, in each case, in accordance with Financial Accounting
         Standards Board Statement 87, utilizing the actuarial assumptions used
         in such Plan's most recent actuarial valuation report), did not exceed
         as of such valuation date the fair market value of the assets of such
         Plan.

                  (c) Neither such Operative Party, nor any of its Subsidiaries,
         nor any ERISA Affiliate has incurred, or, to the best knowledge of such
         Operative Party, could be reasonably expected to incur, any withdrawal
         liability under ERISA to any Multiemployer Plan. Neither such Operative
         Party, nor any of its Subsidiaries, nor any ERISA Affiliate would
         become subject to any withdrawal liability under ERISA if such
         Operative Party or any of its Subsidiaries or any ERISA Affiliate were
         to withdraw completely from all Multiemployer Plans as of the valuation
         date most closely preceding the date on which this representation is
         made or deemed made. Neither such Operative Party nor any of its
         Subsidiaries nor any ERISA Affiliate has received any notification that
         any Multiemployer Plan is in reorganization (within the meaning of
         Section 4241 of ERISA), is insolvent (within the meaning of Section
         4245 of ERISA), or has been terminated (within the meaning of Title IV
         of ERISA), and no Multiemployer Plan is, to the best knowledge of such
         Operative Party, reasonably expected to be in reorganization,
         insolvent, or terminated.

                  (d) No prohibited transaction (within the meaning of Section
         406 of ERISA or Section 4975 of the Code) or breach of fiduciary
         responsibility has occurred with respect to a Plan which has subjected
         or may subject such Operative Party or any of its Subsidiaries or any
         ERISA Affiliate to any liability under Sections 406, 409, 502(i), or
         502(l) of ERISA or Section 4975 of the Code, or under any agreement or
         other instrument pursuant to which such Operative Party or any of its
         Subsidiaries or any ERISA Affiliate has agreed or is required to
         indemnify any Person against any such liability.

                  (e) Neither such Operative Party, nor any of its Subsidiaries
         nor any ERISA Affiliate has any material liability with respect to
         "expected post-retirement benefit obligations" within the meaning of
         the Financial Accounting Standards Board Statement

                                       70

         106. Each Plan which is a welfare plan (as defined in Section 3(1) of
         ERISA) to which Sections 601-609 of ERISA and Section 4980B of the Code
         apply has been administered in compliance in all material respects of
         such sections.

                  (f) Neither the execution and delivery of this Credit
         Agreement nor the consummation of the financing transactions
         contemplated thereunder will involve any transaction which is subject
         to the prohibitions of Sections 404, 406 or 407 of ERISA or in
         connection with which a tax could be imposed pursuant to Section 4975
         of the Code. The representation by the Operative Parties in the
         preceding sentence is made in reliance upon and subject to the accuracy
         of the Lenders' representation in Section 11.16 with respect to their
         source of funds and is subject, in the event that the source of the
         funds used by the Lenders in connection with this transaction is an
         insurance company's general asset account, to the application of
         Prohibited Transaction Class Exemption 95-60, 60 Fed. Reg. 35,925
         (1995), compliance with the regulations issued under Section
         401(c)(1)(A) of ERISA, or the issuance of any other prohibited
         transaction exemption or similar relief, to the effect that assets in
         an insurance company's general asset account do not constitute assets
         of an "employee benefit plan" within the meaning of Section 3(3) of
         ERISA of a "plan" within the meaning of Section 4975(e)(1) of the Code.

         6.12   SUBSIDIARIES.

         Set forth on Schedule 6.12 is a complete and accurate list of all
Subsidiaries of such Operative Party. Information on Schedule 6.12 includes
jurisdiction of incorporation, the number of shares of each class of Capital
Stock outstanding, the number and percentage of outstanding shares of each class
owned (directly or indirectly) by such Operative Party; and the number and
effect, if exercised, of all outstanding options, warrants, rights of conversion
or purchase and all other similar rights with respect thereto. The outstanding
Capital Stock of all such Subsidiaries of the Operative Parties is validly
issued, fully paid and non-assessable and is owned by each such Operative Party,
directly or indirectly, free and clear of all Liens (other than those arising
under or contemplated in connection with the Credit Documents). Other than as
set forth in Schedule 6.12, no Operative Party has outstanding any securities
convertible into or exchangeable for its Capital Stock nor does any such Person
have outstanding any rights to subscribe for or to purchase or any options for
the purchase of, or any agreements providing for the issuance (contingent or
otherwise) of, or any calls, commitments or claims of any character relating to
its Capital Stock. None of the Borrowers own any Subsidiaries. Schedule 6.12 may
be updated from time to time by the Operative Parties by giving written notice
thereof to the Administrative Agent.

         6.13   GOVERNMENTAL REGULATIONS, ETC.

                (a) No part of the proceeds of the Loans will be used, directly
         or indirectly, for the purpose of purchasing or carrying any "margin
         stock" within the meaning of Regulation U, or for the purpose of
         purchasing or carrying or trading in any securities. If requested by
         any Lender or the Administrative Agent, the Borrowers will furnish to
         the Administrative Agent and each Lender a statement to the foregoing
         effect in conformity with the requirements of FR Form U-1 referred to
         in Regulation U. No indebtedness being reduced or retired out of the
         proceeds of the Loans was or will be incurred for the purpose of


                                       71
<PAGE>   77




         purchasing or carrying any margin stock within the meaning of
         Regulation U or any "margin security" within the meaning of Regulation
         T. "Margin stock" within the meaning of Regulation U does not
         constitute more than 25% of the value of the consolidated assets of the
         Borrowers or the Operative Parties. None of the transactions

           basis of GAAP (including the establishment and maintenance of
           appropriate reserves).

                 7.4     COMPLIANCE WITH LAW.

                         Each Operative Party will, and will cause each of its
           Subsidiaries to, comply with all laws, rules, regulations and orders,
           and all applicable restrictions imposed by all Governmental
           Authorities, applicable to it and its property if noncompliance with
           any such law, rule, regulation, order or restriction could reasonably
           be expected to have a Material Adverse Effect.

                 7.5     PAYMENT OF TAXES AND OTHER INDEBTEDNESS.

                         Each Operative Party will, and will cause each of its
           Subsidiaries to, pay and discharge (a) all taxes, assessments and
           governmental charges or levies imposed upon it, or upon its income or
           profits, or upon any of its properties, before they shall become
           delinquent, (b) all lawful claims (including claims for labor,
           materials and supplies) which, if unpaid, might give rise to a Lien
           upon any of its properties, and (c) except as prohibited hereunder,
           all of its other Indebtedness as it shall become due; provided,
           however, that an Operative Party or any of its Subsidiaries shall not
           be required to pay any such tax, assessment, charge, levy, claim or
           Indebtedness which is being contested in good faith by appropriate
           proceedings and as to which adequate reserves therefor have been
           established in accordance with GAAP, unless the failure to make any
           such payment (i) could give rise to an immediate right to foreclose
           on a Lien securing such amounts or (ii) could reasonably be expected
           to have a Material Adverse Effect.

                 7.6     INSURANCE.

                         (a) Each Borrower hereby agrees that it will at all
           times maintain in full force and effect insurance (including, but not
           limited to, liability insurance, property insurance and builders risk
           insurance) in such amounts and covering such risks and liabilities
           and with



                                       79
<PAGE>   85


         such deductibles as are in accordance with normal industry practice and
         the provisions set forth below:

                      (i) The builder's risk insurance policy with respect to
                  each Eligible Project of such Borrower shall be an "all-risk"
                  completed value, non-reporting builder's risk insurance policy
                  and shall contain provisions for a minimum 30-day advance
                  written notice to the Administrative Agent of any intended
                  policy cancellation or non-renewal, (B) a standard mortgagee
                  endorsement designating the Administrative Agent, for the
                  benefit of the Lenders, as mortgagee and loss payee and (C) an
                  endorsement sufficient to eliminate all co-insurance
                  provisions.

                      (ii) The commercial general liability insurance maintained
                  by each of the Borrowers and the general contractor with
                  respect to each Eligible Project of such Borrower shall (A)
                  include a liability limit of not less than $1,000,000 per
                  occurrence and $2,000,000 annually in the aggregate and (B)
                  include worker's compensation coverage in an amount sufficient
                  to satisfy statutory requirements.

                      (iii) The "all-risk" property insurance policy, including
                  flood, earthquake and business interruption insurance with
                  respect to each Eligible Project of such Borrower must (i)
                  contain a replacement cost endorsement sufficient to eliminate
                  all co-insurance provisions, (ii) include provisions for a
                  minimum 30-day advance written notice to the Administrative
                  Agent of any intended policy cancellation or non-renewal and
                  (iii) designate the Administrative Agent, for the benefit of
                  the Lenders, as mortgagee and loss payee in a standard
                  mortgagee endorsement, as its interest may appear.

                  (b) In the event a Borrower fails to maintain insurance as
         required hereunder, the Administrative Agent shall have the right to
         procure such insurance whether or not such Borrower's failure to
         maintain such insurance constitutes a Default or an Event of Default.
         Any amounts paid by the Administrative Agent for insurance shall be due
         and payable to the Administrative Agent upon demand and shall be
         secured by the Collateral Documents.

                  (c) In the event of loss, the applicable Borrower shall
         promptly give written notice thereof to the Administrative Agent and
         the insurance carrier describing the nature and extent of such damage
         or destruction. The Administrative Agent may make proof of loss if not
         made promptly by such Borrower. The Administrative Agent is hereby
         authorized, upon the request and direction of the Required Lenders, to
         adjust, compromise and collect the proceeds of any insurance claims.
         The Borrowers hereby assign to the Administrative Agent, for the
         benefit of the Lenders, the proceeds of any such insurance policies and
         hereby directs and authorizes each insurance company to make payment
         for such loss directly to the Administrative Agent. In the event a
         Borrower shall receive any such insurance proceeds as a result of any
         loss, damage or destruction with respect to the Collateral, such
         Borrower shall immediately pay over such proceeds to the Administrative
         Agent as cash collateral for the Credit Party Obligations. The
         Administrative Agent agrees to release insurance proceeds of $1,000,000
         or less directly to such Borrower for restoration or repair. The
         Administrative Agent agrees to release insurance proceeds in excess of


                                       80
<PAGE>   86


         $1,000,000 to such Borrower for restoration or repair of the Collateral
         damaged provided the following conditions are met:

                           (i)    there exists no Default or Event of Default;

                           (ii)   such Borrower presents sufficient evidence to
                  the Administrative Agent that there are sufficient funds from
                  the insurance proceeds (or that sufficient funds from
                  insurance proceeds can reasonably be expected to be received)
                  and from equity funds, if needed, to completely restore or
                  repair the damaged collateral;

                           (iii)  such Borrower presents sufficient evidence to
                  the Administrative Agent that the damaged Collateral will be
                  restored prior to the Maturity Date;

                           (iv)   the Administrative Agent will not incur any
                  liability to any other Person as a result of such use or
                  release of insurance proceeds; and

                           (v)    the insurance proceeds shall be held by the
                  Administrative Agent and disbursed substantially in accordance
                  with the disbursement procedures under Section 2.2 of this
                  Credit Agreement as repair or restoration progresses as if
                  such proceeds were Loans.

         If the above-referenced conditions of this Section 7.6(c)(i), (ii),
         (iii), (iv) and (v) are not satisfied within ninety (90) days of loss,
         then the Administrative Agent may, at its option, apply any insurance
         proceeds to the payment of the Revolving Loans. The insurance coverage
         of each of the Borrowers is outlined as to carrier, policy number,
         expiration date, type and amount on Schedule 7.6.

         7.7      MAINTENANCE OF PROPERTY.

         Each Operative Party will, and will cause each of its Subsidiaries to,
maintain and preserve its properties and equipment material to the conduct of
its business in good repair, working order and condition, normal wear and tear
and casualty and condemnation excepted, and will make, or cause to be made, to
such properties and equipment from time to time all repairs, renewals,
replacements, extensions, additions, betterments and improvements thereto as may
be needed, to the extent and in the manner customary for companies in similar
businesses.

         7.8      PERFORMANCE OF OBLIGATIONS.

         Each Operative Party will, and will cause each of its Subsidiaries to,
perform in all respects all of its obligations under the terms of all
agreements, indentures, mortgages, security agreements or other debt instruments
to which it is a party or by which it is bound unless the failure to do so could
not have or be reasonably expected to have a Material Adverse Effect.

         The Borrowers will use the proceeds of the Loans for the purposes set
forth in Section 6.14.

         7.10     AUDITS/INSPECTIONS.

                  (a) Upon reasonable notice (and in any event upon no less than
         two (2) Business Days notice) and during normal business hours, each
         Operative Party will permit representatives appointed by the
         Administrative Agent, including, without limitation, independent
         accountants, agents, attorneys, and appraisers to visit and inspect its
         property, including its books and records, its accounts receivable and
         inventory, its facilities and its other business assets, and to make
         photocopies or photographs thereof and to write down and record any
         information such representative obtains and shall permit the
         Administrative Agent or its representatives to investigate and verify
         the accuracy of information provided to the Lenders and to discuss all
         such matters with the officers, employees and representatives of such
         Person. Upon the occurrence and during the continuance of an Event of
         Default, the Operative Parties agree that the Administrative Agent, and
         its representatives, may conduct an audit of the Collateral, at the
         expense of the Operative Parties.

                  (b) Upon reasonable notice (and in any event upon no less than
         two (2) Business Days notice), the Borrowers will permit the
         Administrative Agent and/or its agents or representatives (including,
         without limitation, the Engineer) (at the expense of the Borrowers) to
         enter upon any of the Real Properties for the purpose of inspecting the
         construction of the Facilities.

         and agree that at least 85% of all Facilities shall be either (i)
         Eligible Projects to the extent such Facilities have not been in
         operation for five full fiscal quarters following the date of the first
         resident occupancy of such Facilities or (ii) Stabilized Eligible
         Projects to the extent such Facilities have been in operation for at

                  (a) The Operative Parties shall comply in all material
         respects with, and take reasonable actions to ensure compliance in all
         material respects by all tenants and subtenants, if any, with, all
         applicable Environmental Laws and obtain and comply in all material
         respects with and maintain, and take reasonable actions to ensure that
         all tenants and subtenants obtain and comply in all material respects
         with and maintain, any and all licenses, approvals, notifications,
         registrations or permits required by applicable

                                       82

         Environmental Laws except to the extent that failure to do so would not
         reasonably be expected to have a Material Adverse Effect;

                  (b) The Operative Parties shall conduct and complete all
         investigations, studies, sampling and testing, and all remedial,
         removal and other actions required under Environmental Laws and
         promptly comply in all material respects with all lawful orders and
         directives of all Governmental Authorities regarding Environmental Laws
         except to the extent that the same are being contested in good faith by
         appropriate proceedings and the failure to do or the pendency of such
         proceedings would not reasonably be expected to have a Material Adverse
         Effect; and

                  (c) The Operative Parties shall defend, indemnify and hold
         harmless the Administrative Agent and the Lenders, and their respective
         employees, agents, officers and directors, from and against any and all
         claims, demands, penalties, fines, liabilities, settlements, damages,
         costs and expenses of whatever kind or nature known or unknown,
         contingent or otherwise, arising out of, or in any way relating to the
         violation of, noncompliance with or liability under, any Environmental
         Law applicable to the operations of the Borrowers or the Properties, or
         any orders, requirements or demands of Governmental Authorities related
         thereto, including, without limitation, reasonable attorney's and
         consultant's fees, investigation and laboratory fees, response costs,
         court costs and litigation expenses, except to the extent that any of
         the foregoing arise out of the gross negligence or willful misconduct
         of the party seeking indemnification therefor. The agreements in this
         paragraph shall survive repayment of the Loans and all other amounts
         payable hereunder, and termination of the Commitments.

         If, subsequent to the Closing Date, a Borrower shall acquire (a) any
real property or (b) any intellectual property, securities instruments, chattel
paper or other personal property required to be delivered to the Administrative
Agent as Collateral hereunder or under any of the Collateral Documents, such
Borrower shall notify the Administrative Agent of same in each case as soon as
practicable after the acquisition thereof. Each Operative Party shall take such
action as requested by the Administrative Agent and at its own expense, to
ensure that the Administrative Agent shall have a first priority perfected Lien
in (i) all real property of the Borrowers (whether now owned or hereafter
acquired) and (ii) all personal property of the Borrowers (whether now owned or
hereafter acquired), subject in each case only to Permitted Liens.

         7.14     YEAR 2000 COMPLIANCE.

         Each Operative Party will promptly notify the Administrative Agent in
the event such Operative Party discovers or determines that any computer
application that is material to its or any of its Subsidiaries' business and
operations will not be Year 2000 compliant, except to the extent that such
failure could not reasonably be expected to have a Material Adverse Effect.

                           (i)  The Parent and the Pool A Borrowers agree that
                  they will reimburse the Lenders for and hereby hold the
                  Lenders harmless from all fines or penalties made or levied
                  against any of the Lenders by any Governmental Authority as a
                  result of or in connection with (i) the use of Materials of
                  Environmental Concern at any Pool A Property, (ii) the use of

                  of any release of any Materials of Environmental Concern onto
                  the ground or into the water or air from or upon any Pool A
                  Property at any time. The Parent and the Pool A Borrowers also
                  agree that they will reimburse the Lenders for and indemnify
                  and hold the Lenders harmless from any and all costs and
                  expenses (including reasonable attorneys' fees) and for all
                  civil judgments or penalties incurred, entered, assessed, or
                  levied against any of the Lenders as a result of a Pool A
                  Borrower's use of Materials of Environmental Concern at any
                  Pool A Property or as a result of any release of any Materials
                  of Environmental Concern on the ground or into the water or

                  incurred by the Lenders as a result of such a civil action,
                  including but not limited to reasonable attorneys' fees. The
                  Parent's and the Pool A Borrowers' obligations under this
                  Section 7.17(i) shall survive the repayment of the Loans and
                  any deed in lieu of foreclosure or any foreclosure of a
                  Mortgage on a Pool A Property.

                           (ii) The Parent and the Pool B Borrowers agree that

                  of any release of any Materials of Environmental Concern onto
                  the ground or into the water or air from or upon any Pool B

                  agree that they will reimburse the Lenders for and indemnify
                  and hold the Lenders harmless from any and all costs and

                  levied against any of the Lenders as a result of a Pool B
                  Borrower's use of Materials of Environmental Concern at any
                  Pool B Property or as a result of any release of any Materials
                  of Environmental Concern on the ground or into the water or
                  air by a Pool B Borrower from or upon any Pool B Property.
                  Such reimbursement or indemnification shall include but not be
                  limited to any and all judgments or penalties to recover the
                  costs of cleanup of any such release by a Pool B Borrower from

                  incurred by the Lenders as a result of such a civil action,

                  Parent's and the Pool B Borrowers' obligations under this
                  Section 7.17(ii) shall survive the repayment of the Loans and
                  any deed in lieu of foreclosure or any foreclosure of a
                  Mortgage on a Pool B Property.

                           (iii) The Parent and the Pool C Borrowers agree that
                  they will reimburse the Lenders for and hereby hold the

                  against any of the Lenders by any Governmental Authority as a
                  result of or in connection with (i) the use of Materials of

              or performance relating to such Indebtedness or contained in any
              instrument or agreement evidencing, securing or relating thereto,
              or any other event or condition shall occur or condition exist,
              the effect of which default or other event or condition is to
              cause, or permit, the holder or holders of such Indebtedness (or
              trustee or agent on behalf of such holders) to cause (determined
              without regard to whether any notice or lapse of time is
              required), any such Indebtedness to become due prior to its stated
              maturity; or (C) any such Indebtedness shall be declared due and
              payable, or required to be prepaid other than by a regularly
              scheduled required prepayment, prior to the stated maturity
              thereof.

              (v)   Judgments. One or more judgments or decrees shall be entered
         against any Pool C Borrower involving a liability of $100,000 or more
         in the aggregate (to the extent not paid or fully covered by insurance
         provided by a carrier who has acknowledged coverage and has the ability
         to perform) and any such judgments or decrees shall not have been
         vacated, discharged or stayed or bonded pending appeal within 30 days
         from the entry thereof.

         9.2  ACCELERATION; REMEDIES.

         Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the requisite Lenders
(pursuant to the voting requirements of Section 11.6) or cured to the
satisfaction of the requisite Lenders (pursuant to the voting procedures in
Section 11.6), the Administrative Agent shall, upon the request and direction of
the Required Lenders, by written notice to the Credit Parties, take any of the
following actions:

              (a)  Termination of Commitments. Declare the Commitments
         terminated whereupon the Commitments shall be immediately terminated.

              (b)  Acceleration. Declare the unpaid principal of and any
         accrued interest in respect of all Loans and any and all other
         indebtedness or obligations of any and every kind owing by the Credit
         Parties to the Administrative Agent and/or any of the Lenders hereunder
         to be due whereupon the same shall be immediately due and payable
         without presentment, demand, protest or other notice of any kind, all
         of which are hereby waived by the Credit Parties.

              (c)  Enforcement of Rights. Enforce any and all rights and
         interests created and existing under the Credit Documents including,
         without limitation, all rights and remedies existing under the
         Collateral Documents, all rights and remedies against a Guarantor and
         all rights of set-off.


                                       99
<PAGE>   105

         Notwithstanding the foregoing, if an Event of Default specified in
Section 9.1(a)(vi) shall occur with respect to a Credit Party, then the
Commitments shall automatically terminate and all Loans, all accrued interest in
respect thereof, all accrued and unpaid Fees and other indebtedness or
obligations owing to the Administrative Agent and/or any of the Lenders
hereunder automatically shall immediately become due and payable without the
giving of any notice or other action by the Administrative Agent or the Lenders.

         Notwithstanding anything contained herein to the contrary, the
Administrative Agent and the Lenders shall not take any of the actions
referenced above in subsections (a), (b) or (c) of this Section 9.2 following
the occurrence of a Pool A Event of Default, a Pool B Event of Default or a Pool
C Event of Default; provided, however, the Administrative Agent and the Lenders
shall be free to exercise any of the rights and remedies identified in this
Section 9.2 on account of any such Pool A Event of Default, Pool B Event of
Default or Pool C Event of Default (x) if any such Pool A Event of Default, Pool
B Event of Default or Pool C Event of Default is not remedied within 60 days of
the occurrence of such Pool A Event of Default, Pool B Event of Default or Pool
C Event of Default respectively or (y) upon the occurrence of an Event of
Default which has not been waived by the requisite Lenders (pursuant to the
voting requirements of Section 11.6).


                                   SECTION 10

                                AGENCY PROVISIONS

         10.1  APPOINTMENT, POWERS AND IMMUNITIES.

               (a) Each Lender hereby irrevocably appoints and authorizes the
         Administrative Agent to act as its agent under this Credit Agreement
         and the other Credit Documents with such powers and discretion as are
         specifically delegated to the Administrative Agent by the terms of this
         Credit Agreement and the other Credit Documents, together with such
         other powers as are reasonably incidental thereto. The Administrative
         Agent (which term as used in this sentence and in Section 10.5 and the
         first sentence of Section 10.6 hereof shall include its Affiliates and
         its own and its Affiliates' officers, directors, employees, and
         agents): (a) shall not have any duties or responsibilities except those
         expressly set forth in this Credit Agreement and shall not be a trustee
         or fiduciary for any Lender; (b) shall not be responsible to the
         Lenders for any recital, statement, representation, or warranty
         (whether written or oral) made in or in connection with any Credit
         Document or any certificate or other document referred to or provided
         for in, or received by any of them under, any Credit Document, or for
         the value, validity, effectiveness, genuineness, enforceability, or
         sufficiency of any Credit Document, or any other document referred to
         or provided for therein or for any failure by any Credit Party or any
         other Person to perform any of its obligations thereunder; (c) shall
         not be responsible for or have any duty to ascertain, inquire into, or
         verify the performance or observance of any covenants or agreements by
         any Credit Party or the satisfaction of any condition or to inspect the
         property (including the books and records) of any Credit Party or any
         of its Subsidiaries or Affiliates; (d) shall not be required to
         initiate or conduct any litigation or collection proceedings under any
         Credit Document;



                                      100
<PAGE>   106

         and (e) shall not be responsible for any action taken or omitted to be
         taken by it under or in connection with any Credit Document, except for
         its own gross negligence or willful misconduct. The Administrative
         Agent may employ agents and attorneys-in-fact and shall not be
         responsible for the negligence or misconduct of any such agents or
         attorneys-in-fact selected by it with reasonable care. The
         Administrative Agent agrees that it will administer the Loans and the
         Credit Documents in a manner consistent with that ordinarily employed
         by the Administrative Agent in the administration of similar loans for
         its own account.

               (b) Each Lender hereby consents to and approves the terms of
         the Alterra Guaranty Agreement and the HCR Guaranty Agreement. By
         execution hereof, the Lenders authorize and direct the Administrative
         Agent to enter into the Alterra Guaranty Agreement and the HCR Guaranty
         Agreement on behalf of the Lenders.

         10.2  RELIANCE BY ADMINISTRATIVE AGENT.

               (a) The Administrative Agent shall be entitled to rely upon
         any certification, notice, instrument, writing, or other communication
         (including, without limitation, any thereof by telephone or telecopy)
         believed by it to be genuine and correct and to have been signed, sent
         or made by or on behalf of the proper Person or Persons, and upon
         advice and statements of legal counsel (including counsel for any
         Credit Party), independent accountants, and other experts selected by
         the Administrative Agent. The Administrative Agent may deem and treat
         the payee of any Note as the holder thereof for all purposes hereof
         unless and until the Administrative Agent receives and accepts an
         Assignment and Acceptance executed in accordance with Section 11.3(b)
         hereof. As to any matters not expressly provided for by this Credit
         Agreement, the Administrative Agent shall not be required to exercise
         any discretion or take any action, but shall be required to act or to
         refrain from acting (and shall be fully protected in so acting or
         refraining from acting) upon the instructions of the Required Lenders,
         and such instructions shall be binding on all of the Lenders; provided,
         however, that the Administrative Agent shall not be required to take
         any action that exposes the Administrative Agent to personal liability
         or that is contrary to any Credit Document or applicable law or unless
         it shall first be indemnified to its satisfaction by the Lenders
         against any and all liability and expense which may be incurred by it
         by reason of taking any such action.

               (b) For purposes of determining compliance with the conditions
         specified in Section 5.1, each Lender that has executed this Credit
         Agreement shall be deemed to have consented to, approved or accepted or
         to be satisfied with, each document or other matter either sent by the
         Administrative Agent to such Lender for consent, approval, acceptance
         or satisfaction, or required thereunder to be consented to or approved
         by or acceptable or satisfactory to the Lender.


                                      101
<PAGE>   107

         10.3  DEFAULTS.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default or Event of Default unless the
Administrative Agent has received written notice from a Lender or a Credit Party
specifying such Default or Event of Default and stating that such notice is a
"Notice of Default". In the event that the Administrative Agent receives such a
notice of the occurrence of a Default or Event of Default, the Administrative
Agent shall give prompt notice thereof to the Lenders. The Administrative Agent
shall (subject to Section 10.2 hereof) take such action with respect to such
Default or Event of Default as shall reasonably be directed by the Required
Lenders, provided that, unless and until the Administrative Agent shall have
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interest of the Lenders.

         10.4  RIGHTS AS A LENDER.

         With respect to its Commitment and the Loans made by it, Bank of
America (and any successor acting as Administrative Agent) in its capacity as a
Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as the
Administrative Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Administrative Agent in its individual
capacity. Bank of America (and any successor acting as Administrative Agent) and
its Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in, provide services to, and
generally engage in any kind of lending, trust, or other business with any
Credit Party or any of its Subsidiaries or Affiliates as if it were not acting
as Administrative Agent, and Bank of America (and any successor acting as
Administrative Agent) and its Affiliates may accept fees and other consideration
from any Credit Party or any of its Subsidiaries or Affiliates for services in
connection with this Credit Agreement or otherwise without having to account for
the same to the Lenders. The Lenders acknowledge that, pursuant to such
activities, Bank of America or its Affiliates may receive information regarding
a Credit Party or any of its Affiliates (including information that may be
subject to confidentiality obligations in favor of a Credit Party or any of its
Subsidiaries) and acknowledge that the Administrative Agent shall be under no
obligation to provide such information to them.

         10.5  INDEMNIFICATION.

         The Lenders agree to indemnify the Administrative Agent and each of its
Affiliates (to the extent not reimbursed under Section 11.5 hereof, but without
limiting the obligations of the Credit Parties under such Section) ratably in
accordance with their respective Commitments, for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including attorneys' fees), or disbursements of any kind and nature
whatsoever that may be imposed on, incurred by or asserted against the
Administrative Agent or any of its Affiliates (including by any Lender) in any
way relating to or arising out of any Credit Document or the transactions
contemplated thereby or any action taken or omitted by the Administrative Agent
or any of its Affiliates under any Credit Document (including any of the
foregoing arising from the negligence of the Administrative Agent or any of its
Affiliates); provided that no



                                      102
<PAGE>   108

Lender shall be liable for any of the foregoing to the extent they arise from
the gross negligence or willful misconduct of the Person to be indemnified or
the breach by any such Person of its obligations under the Credit Documents.
Without limitation of the foregoing, each Lender agrees to reimburse the
Administrative Agent and each of its Affiliates promptly upon demand for its
ratable share of any costs or expenses payable by the Credit Parties under
Section 11.5, to the extent that the Administrative Agent or any of its
Affiliates is not promptly reimbursed for such costs and expenses by the Credit
Parties. The agreements in this Section 10.5 shall survive the repayment of the
Loans and other obligations under the Credit Documents and the termination of
the Commitments hereunder.

         10.6  NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Lender agrees that it has, independently and without reliance on
the Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Credit Parties and their Subsidiaries and decision to enter into this Credit
Agreement and that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
analysis and decisions in taking or not taking action under the Credit
Documents. Except for notices, reports, and other documents and information
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition, or business of any Credit Party or any of its Subsidiaries
or Affiliates that may come into the possession of the Administrative Agent or
any of its Affiliates.

         10.7  SUCCESSOR ADMINISTRATIVE AGENT.

         The Administrative Agent may resign at any time by giving notice
thereof to the Lenders and the Credit Parties. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty (30)
days after the retiring Administrative Agent's giving of notice of resignation,
then the retiring Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent which shall be a commercial bank organized under
the laws of the United States of America having combined capital and surplus of
at least $100,000,000. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor, such successor shall thereupon succeed to and
become vested with all the rights, powers, discretion, privileges, and duties of
the retiring Administrative Agent, and the retiring Administrative Agent shall
be discharged from its duties and obligations hereunder. If no successor
Administrative Agent has accepted appointment as Administrative Agent within
thirty (30) days after the retiring Administrative Agent's giving notice of
resignation, the retiring Administrative Agent's resignation shall nevertheless
become effective and the Lenders shall perform all duties of the Administrative
Agent hereunder until such time, if any, as the Required Lenders appoint a
successor Administrative Agent as provided for above. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Section 10 shall



                                      103
<PAGE>   109

continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Administrative Agent.

         11.2  RIGHT OF SET-OFF; ADJUSTMENTS.

         Upon the occurrence and during the continuance of any Event of Default,
each Lender (and each of its Affiliates) is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender (or any
of its Affiliates) to or for the credit or the account of any Operative Party
against any and all of the obligations of such Person now or hereafter existing
under this Credit Agreement, under the Notes, under any other Credit Document or
otherwise, irrespective of whether such Lender shall have made any demand
hereunder or thereunder and although such obligations may be unmatured. Each
Lender agrees promptly to notify any affected Operative Party after any such
set-off and application made by such Lender; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 11.2 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) that such Lender may have.

         11.3  BENEFIT OF AGREEMENT.

               (a) This Credit Agreement shall be binding upon and inure to the
         benefit of and be enforceable by the respective successors and assigns
         of the parties hereto; provided that none of the Credit Parties may
         assign or transfer any of its interests and obligations without prior
         written consent of the Lenders; provided further that the rights of
         each Lender to transfer, assign or grant participations in its rights
         and/or obligations hereunder shall be limited as set forth in this
         Section 11.3.

               (b) Each Lender may assign to one or more Eligible Assignees all
         or a portion of its rights and obligations under this Credit Agreement
         (including, without limitation, all or a portion of its Loans, its
         Notes, and its Commitment); provided, however, that

                   (i)   each such assignment shall be to an Eligible Assignee;

                   (ii)  except in the case of an assignment to another Lender
               or an assignment of all of a Lender's rights and obligations
               under this Credit Agreement, any such partial assignment shall be
               in an amount at least equal to


                                      106
<PAGE>   112


               $10,000,000 (or, if less, the remaining amount of the Commitment
               being assigned by such Lender) or an integral multiple of
               $1,000,000 in excess thereof;

                   (iii) each such assignment by a Lender shall be of a
               constant, and not varying, percentage of all of its rights and
               obligations under this Credit Agreement and the Notes; and

                   (iv)  the parties to such assignment shall execute and
               deliver to (A) the Administrative Agent for its acceptance an
               Assignment and Acceptance in the form of Exhibit 11.3(b) hereto
               and (B) so long as no Event of Default shall have occurred and be
               continuing at the time of such assignment, the Designated
               Borrowers for their acceptance (such acceptance not to be
               unreasonably withheld) an Assignment and Acceptance in the form
               of Exhibit 11.3(b), together with any Note subject to such
               assignment and a processing fee of $3,500.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance, the assignee thereunder shall be a party hereto and, to the
         extent of such assignment, have the obligations, rights, and benefits
         of a Lender hereunder and the assigning Lender shall, to the extent of
         such assignment, relinquish its rights and be released from its
         obligations under this Credit Agreement. Upon the consummation of any
         assignment pursuant to this Section 11.3(b), the assignor, the
         Administrative Agent and the Credit Parties shall make appropriate
         arrangements so that, if required, new Notes are issued to the assignor
         and the assignee. If the assignee is not a United States person under
         Section 7701(a)(30) of the Code, it shall deliver to the Credit Parties
         and the Administrative Agent certification as to exemption from
         deduction or withholding of Taxes in accordance with Section 3.11.

               (c) The Administrative Agent shall maintain at its address

         delivered to and accepted by it and a register for the recordation of
         the names and addresses of the Lenders and the Commitment of, and
         principal amount of the Loans owing to, each Lender from time to time
         (the "Register"). The entries in the Register shall be conclusive and
         binding for all purposes, absent manifest error, and the Credit
         Parties, the Administrative Agent and the Lenders may treat each Person
         whose name is recorded in the Register as a Lender hereunder for all
         purposes of this Credit Agreement. The Register shall be available for
         inspection by the Credit Parties or any Lender at any reasonable time
         and from time to time upon reasonable prior notice.

               (d) Upon its receipt of an Assignment and Acceptance executed by
         the parties thereto, together with any Note subject to such assignment
         and payment of the processing fee, the Administrative Agent shall, if
         such Assignment and Acceptance has been completed and is in
         substantially the form of Exhibit 11.3(b) hereto, (i) accept such
         Assignment and Acceptance, (ii) record the information contained
         therein in the Register and (iii) give prompt notice thereof to the
         parties thereto.

               (e) Each Lender may sell participations to one or more Persons in
         all or a portion of its rights, obligations or rights and obligations
         under this Credit Agreement



                                      107

         (including all or a portion of its Commitment or its Loans); provided,
         however, that (i) such Lender's obligations under this Credit Agreement
         shall remain unchanged, (ii) such Lender shall remain solely
         responsible to the other parties hereto for the performance of such
         obligations, (iii) the participant shall be entitled to the benefit of
         the yield protection provisions contained in Sections 3.7 through 3.12,
         inclusive, and the right of set-off contained in Section 11.2, and (iv)
         the Credit Parties shall continue to deal solely and directly with such
         Lender in connection with such Lender's rights and obligations under
         this Credit Agreement, and such Lender shall retain the sole right to
         enforce the obligations of the Credit Parties relating to the Credit
         Party Obligations owing to such Lender and to approve any amendment,
         modification, or waiver of any provision of this Credit Agreement
         (other than amendments, modifications, or waivers decreasing the amount
         of principal of or the rate at which interest is payable on such Loans
         or Notes, extending any scheduled principal payment date or date fixed
         for the payment of interest on such Loans or Notes, or extending its
         Commitment).

               (f) Notwithstanding any other provision set forth in this Credit
         Agreement, any Lender may at any time assign and pledge all or any
         portion of its Loans and its Notes to any Federal Reserve Bank as
         collateral security pursuant to Regulation A and any Operating Circular
         issued by such Federal Reserve Bank. No such assignment shall release
         the assigning Lender from its obligations hereunder.

               (g) Any Lender may furnish any information concerning the Credit
         Parties in the possession of such Lender from time to time to assignees
         and participants (including prospective assignees and participants),
         subject, however, to the provisions of Section 11.14 hereof.

         11.4  NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Administrative Agent or any
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Administrative Agent or any
Lender and any of the Credit Parties shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
or under any other Credit Document preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder or
thereunder. The rights and remedies provided herein are cumulative and not
exclusive of any rights or remedies which the Administrative Agent or any Lender
would otherwise have. No notice to or demand on any Credit Party in any case
shall entitle the Credit Parties to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Administrative Agent or the Lenders to any other or further action in any
circumstances without notice or demand.

         11.5  EXPENSES; INDEMNIFICATION.

         (a) The Operative Parties jointly and severally agree to pay on demand
all costs and expenses of the Administrative Agent in connection with the

limitation, the reasonable fees and expenses of counsel for the Administrative
Agent with respect thereto and with respect to advising the Administrative Agent
as to its rights and responsibilities under the Credit Documents. The Operative
Parties further jointly and severally agree to pay on demand all costs and
expenses of the Administrative Agent and the Lenders, if any (including, without
limitation, reasonable attorneys' fees and expenses), in connection with the
enforcement (whether through negotiations, legal proceedings, or otherwise) and
attempted enforcement of the Credit Documents and the other documents to be
delivered hereunder and the preservation of any rights and remedies under this
Credit Agreement or any other Credit Document during the existence of an Event
of Default or after the acceleration of the Loans (including, without
limitation) in connection with any "workout" or restructuring regarding the
Loans, and including, without limitation, any insolvency proceeding or appellate
proceeding).

         (b) The Operative Parties jointly and severally agree to indemnify and
hold harmless the Administrative Agent and each Lender and each of their
Affiliates and their respective officers, directors, employees, agents, and
advisors (each, an "Indemnified Party") from and against any and all claims,
damages, losses, liabilities, costs, and expenses (including, without
limitation, reasonable attorneys' fees) that may be incurred by or asserted or
awarded against any Indemnified Party, in each case arising out of or in
connection with or by reason of (including, without limitation, in connection
with any investigation, litigation, or proceeding or preparation of defense in
connection therewith) the Credit Documents, any of the transactions contemplated
herein or the actual or proposed use of the proceeds of the Loans (including to
the extent arising from the negligence of the Indemnified Party), except to the
extent such claim, damage, loss, liability, cost, or expense is found in a
final, non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnified Party's gross negligence or willful misconduct.
In the case of an investigation, litigation or other proceeding to which the
indemnity in this Section 11.5 applies, such indemnity shall be effective
whether or not such investigation, litigation or proceeding is brought by any of
the Operative Parties, their respective directors, shareholders or creditors or
an Indemnified Party or any other Person or any Indemnified Party is otherwise a
party thereto and whether or not the transactions contemplated hereby are
consummated. The Operative Parties agree not to assert any claim against the
Administrative Agent, any Lender, any of their Affiliates, or any of their
respective directors, officers, employees, attorneys, agents, and advisers, on
any theory of liability, for special, indirect, consequential, or punitive
damages arising out of or otherwise relating to the Credit Documents, any of the
transactions contemplated herein or the actual or proposed use of the proceeds
of the Loans.

         (c) Without prejudice to the survival of any other agreement of the
Operative Parties hereunder, the agreements and obligations of the Operative
Parties contained in this Section 11.5 shall survive the repayment of the Loans
and other obligations under the Credit Documents and the termination of the
Commitments hereunder.

                   (d)  increase the Commitment of a Lender over the amount

               of any Default or Event of Default or mandatory reduction in the
               Commitments shall not constitute a change in the terms of any
               Commitment of any Lender),

               Agent may, without consent from any other Lender, release any

                   (h)  reduce any percentage specified in, or otherwise modify,
               the definition of Required Lenders, or

               its or their rights and obligations under (or in respect of) the
               Credit Documents except as permitted thereby; and


                                      110
<PAGE>   116

               (ii)   without the consent of the Administrative Agent, no
         provision of Section 10 may be amended.

         Notwithstanding the fact that the consent of all the Lenders is
         required in certain circumstances as set forth above, (x) each Lender
         is entitled to vote as such Lender sees fit on any bankruptcy
         reorganization plan that affects the Loans, and each Lender
         acknowledges that the provisions of Section 1126(c) of the Bankruptcy
         Code supersedes the unanimous consent provisions set forth herein and

         LENDERS, EACH OF THE Operative PARTIES HEREBY IRREVOCABLY WAIVES ALL

                                      113
<PAGE>   119

               (a) no part of such funds constitutes assets allocated to any
         separate account maintained by such Lender in which any employee
         benefit plan (or its related trust) has any interest;

         allocated to any separate account maintained by such Lender, such
         Lender has disclosed to the Borrowers the name of each employee benefit
         plan whose assets in such account exceed 10% of the total assets of
         such account as of the date of such purchase (and, for purposes of this
         subsection (b), all employee benefit plans maintained by the same
         employer or employee organization are deemed to be a single plan);

               (c) to the extent that any part of such funds constitutes assets
         of an insurance company's general account, such insurance company has
         complied with all of the requirements of the regulations issued under
         Section 401(c)(1)(A) of ERISA; or

               (d) such funds constitute assets of one or more specific benefit
         plans which such Lender has identified in writing to the Borrowers.

                               GUARANTY AGREEMENT

         THIS GUARANTY AGREEMENT dated as of September 30, 1999 (the "Guaranty")
is given by Alterra Healthcare Corporation, a Delaware corporation (the
"Partner" or "Alterra"), in favor of BANK OF AMERICA, N.A., as Administrative
Agent (in such capacity, the "Administrative Agent") for the Lenders under the
Credit Agreement referenced below.

                               W I T N E S S E T H

         WHEREAS, the Borrowers, HCR/Alterra Development, LLC, the Lenders and
the Administrative Agent have entered into that certain Credit Agreement (each
as defined below);

         WHEREAS, this Guaranty is a condition precedent to the obligations of
the Lenders to make loans and extensions of credit to the Borrowers under the
Credit Agreement;

         NOW, THEREFORE, IN CONSIDERATION of the premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Partner hereby agrees as follows:

                                    SECTION 1
                                   DEFINITIONS

         1.1      CERTAIN DEFINITIONS.

         Unless otherwise defined herein or the context otherwise requires,
terms used in this Guaranty, including its preamble and recitals, have the
meanings provided in the Credit Agreement:

                  "Acquisition", by any Person, means the acquisition by such
         Person of all of the Capital Stock or all or substantially all of the
         Property of another Person, whether or not involving a merger or
         consolidation with such other Person.

                  "Affiliate" means, with respect to any Person, any other
         Person (i) directly or indirectly controlling or controlled by or under
         direct or indirect common control with such Person or (ii) directly or
         indirectly owning or holding five percent (5%) or more of the Capital
         Stock in such Person. For purposes of this definition, "control" when
         used with respect to any Person means the power to direct the
         management and policies of such Person, directly or indirectly, whether
         through the ownership of voting securities, by contract or otherwise;

extension or renewal. The Partner further agrees to (x) assume all

collection, is a continuing guaranty, and shall apply to all Guaranteed
Obligations whenever owing.

         2.2      GUARANTEED OBLIGATIONS UNCONDITIONAL.

         The obligations of the Partner under Section 2.1 are absolute and
unconditional, irrespective of the value, genuineness, validity, regularity or
enforceability of any of the Credit Documents or Hedging Agreements, or any
other agreement or instrument referred to therein, or any substitution,
compromise, release, impairment or exchange of any other guarantee of or
security for any of the Guaranteed Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
which might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this Section 2.2 that the
obligations of the Partner hereunder shall be absolute and unconditional under
any and all circumstances. Without limiting the generality of the foregoing, it
is agreed that, to the fullest extent permitted by law, the occurrence of any
one or more of the following shall not alter or impair the liability of the
Partner hereunder which shall remain absolute and unconditional as described
above:

                  (a) at any time or from time to time, without notice to the
         Partner, the time for any performance of or compliance with any of the
         Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (b) any of the acts mentioned in any of the provisions of any
         of the Credit Documents or Hedging Agreements or any other agreement or
         instrument referred to in the Credit Documents or Hedging Agreements
         shall be done or omitted;

         Credit Documents or Hedging Agreements or any other agreement or
         instrument referred to in the Credit Documents or Hedging Agreements
         shall be waived or any other guarantee of any of the Guaranteed
         Obligations or any security therefor shall be released, impaired or
         exchanged in whole or in part or otherwise dealt with;

                  (d) any Lien granted to, or in favor of, the Administrative

                                       7
<PAGE>   8


                  (e) any addition, substitution, replacement or release of a
         Borrower pursuant to the terms of the Credit Agreement, with or without
         the consent of the Partner or with or without any notice of such
         addition, substitution, replacement or release being provided to the
         Partner; or

                  (f) any of the Guaranteed Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of the Partner) or shall be subordinated to the claims of
         any Person (including, without limitation, any creditor of the
         Partner).

With respect to its obligations hereunder, the Partner hereby expressly waives
diligence, presentment, demand of payment, protest, notice of acceptance of this
Guaranty and of extensions of credit which may constitute Guaranteed
Obligations, notice of amendments, waivers or supplements to the Credit
Documents or Hedging Agreements or the compromise, release or exchange of
collateral or security and all other notices whatsoever, and any requirement
that the Administrative Agent or any Lender exhaust any right, power or remedy
or proceed against any Person under any of the Credit Documents or Hedging
Agreements or any other agreement or instrument referred to in the Credit
Documents or against any other Person under any other guarantee of, or security
for, any of the Guaranteed Obligations.

         2.3      REINSTATEMENT.

         Neither the Partner's obligations hereunder nor any remedy for the
enforcement thereof shall be impaired, modified, changed or released in any
manner whatsoever by an impairment, modification, change, release or limitation
of the liability of the Borrowers, by reason of any Borrower's bankruptcy or
insolvency or by reason of the invalidity or unenforceability of all or any
portion of the Guaranteed Obligations. The obligations of the Partner under this
Guaranty shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Person in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy
or reorganization or otherwise, and the Partner agrees that it will indemnify
the Administrative Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, reasonable fees and expenses of
counsel) incurred by the Administrative Agent or such Lender in connection with
such rescission or restoration, including any such costs and expenses incurred
in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy,
insolvency or similar law.

         2.4      CERTAIN ADDITIONAL WAIVERS.

         The Partner agrees that this Guaranty may be enforced by the
Administrative Agent and the Lenders without the necessity of resorting to or
exhausting any other security or collateral and without the necessity at any
time of having recourse to the Borrowers under the Credit Agreement, any Hedging
Agreement or any collateral securing the Guaranteed Obligations or otherwise,
and the Partner agrees not to assert any right to require the Administrative
Agent and the Lenders to proceed against any Borrower or any other Person
(including any co-guarantor) or



                                       8
<PAGE>   9


to require the Administrative Agent and the Lenders to pursue any other remedy
or enforce any other right. The Partner further agrees that it shall have no
right of subrogation, reimbursement or indemnity, nor any right of recourse to
security, if any, for the Guaranteed Obligations so long as any amounts payable
to the Administrative Agent or the Lenders in respect of the Guaranteed
Obligations shall remain outstanding (other than contingent indemnification
obligations) and until all of the Commitments shall have expired or been
terminated. The Partner further acknowledges and agrees that nothing contained
in this Guaranty shall prevent the Administrative Agent or the Lenders from
suing any Borrower in respect of his obligations under the Credit Agreement, any
Hedging Agreement and the other Credit Documents or foreclosing on any security
interest or lien on any collateral securing the Guaranteed Obligations or from
exercising any other rights available to the Administrative Agent and the
Lenders under the Credit Documents or Hedging Agreements if neither the
Borrowers nor the Partner timely perform their obligations, and the exercise of
any of such rights and completion of any such foreclosure proceedings shall not
constitute a discharge of any of the Partner's obligations hereunder unless as a
result thereof the Guaranteed Obligations shall have been paid in full (other
than contingent indemnification obligations) and all of the Commitments shall
have terminated or expired, it being the purpose and intent that the Partner's
obligations hereunder be absolute, irrevocable, independent and unconditional
under all circumstances.

         2.5      REMEDIES.

         The Partner agrees that, to the fullest extent permitted by law, as
between the Partner, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, the Guaranteed Obligations may be declared to be
forthwith due and payable (as provided in Section 9.2 of the Credit Agreement)
for purposes of Section 2.1 notwithstanding any stay, injunction or other
prohibition preventing such declaration (or preventing such Guaranteed
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or such Guaranteed
Obligations being deemed to have become automatically due and payable), such
Guaranteed Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Partner for purposes of Section
2.1.

         2.6      FURTHER REPRESENTATIONS AND WARRANTIES.

         The Partner agrees that the Administrative Agent and the Lenders will
have no obligation to investigate the financial condition or affairs of any
Borrower for the benefit of the Partner nor to advise the Partner of any fact
respecting, or any change in, the financial condition or affairs of any Borrower
which might come to the knowledge of the Administrative Agent or any Lender at
any time, whether or not the Administrative Agent or any Lender knows or
believes or has reason to know or believe that any such fact or change is
unknown to the Partner or might (or does) materially increase the risk of the
Partner as Partner or might (or would) affect the willingness of the Partner to
continue as a guarantor with respect to the Guaranteed Obligations.

         2.7      ADDITIONAL LIABILITY OF PARTNER.

         If the Partner is or becomes liable for any indebtedness owing by any
Borrower to the Administrative Agent or any Lender by endorsement or otherwise
other than under this Guaranty, such liability shall not be in any manner
impaired or reduced hereby but shall have all and the same force and effect it
would have had if this Guaranty had not existed and the Partner's liability
hereunder shall not be in any manner impaired or reduced thereby.


                                    SECTION 3
                         REPRESENTATIONS AND WARRANTIES

         Alterra hereby represents to the Administrative Agent and each Lender
that:

         3.1      FINANCIAL CONDITION.

         The financial statements delivered to the Lenders pursuant to Section
4.1(a) and (b), (i) have been prepared in accordance with GAAP and (ii) present
fairly (on the basis disclosed in the footnotes to such financial statements)
the financial condition, results of operations and cash flows of Alterra and its
Subsidiaries as of such date and for such periods. Since December 31, 1998, (i)
there has been no sale, transfer or other disposition by Alterra or its
Subsidiaries of any material part of the business or material property of
Alterra and its Subsidiaries, and (ii) no purchase or other acquisition by any
of them of any business or property (including any capital stock of any other
Person) material in relation to financial condition of Alterra and its
Subsidiaries, which is not reflected in the foregoing financial statements or in
the notes thereto and has not otherwise been disclosed in writing to the Lenders
on or prior to the Closing Date. As of the Closing Date (other than the
liabilities of Alterra arising from the transactions contemplated by the Credit
Documents), Alterra and its Subsidiaries have no material liabilities
(contingent or otherwise) that are not reflected in the foregoing financial
statements, in the notes thereto or Alterra's report on Form 10-K or Form 10-Q,
as applicable.

         3.2      NO MATERIAL CHANGE.

                  (a) Since December 31, 1998 (a) there has been no development
         or event relating to or affecting any Consolidated Party which has had
         or could reasonably be expected to have a Material Adverse Effect.

                  (b) Since the Closing Date, except as otherwise permitted
         under this Guaranty, no dividends or other distributions have been
         declared, paid or made upon the Capital Stock in an Consolidated Party
         nor has any of the Capital Stock in any Consolidated Party been
         redeemed, retired, purchased or otherwise acquired for value.

         3.3      ORGANIZATION AND GOOD STANDING.

         Each of the Consolidated Parties (a) is duly organized, validly
existing and is in good standing under the laws of the jurisdiction of its
incorporation or organization, (b) has the corporate or other necessary power
and authority, and the legal right, to own and operate its property, to lease
the property it operates as lessee and to conduct the business in which it is
currently engaged and



                                       10
<PAGE>   11


(c) is duly qualified as a foreign entity and in good standing under the laws of
each jurisdiction where its ownership, lease or operation of property or the
conduct of its business requires such qualification, other than in such
jurisdictions where the failure to be so qualified and in good standing could
reasonably be expected to have a Material Adverse Effect.

         3.4      POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS.

         Alterra has the corporate or other necessary power and authority, and
the legal right, to make, deliver and perform the Credit Documents to which it
is a party, and has taken all necessary corporate action to authorize the
execution, delivery and performance of the Credit Documents to which it is a
party. No consent or authorization of, filing with, notice to or other similar
act by or in respect of, any Governmental Authority or any other Person is
required to be obtained or made by or on behalf of Alterra in connection with
the execution, delivery, performance, validity or enforceability of the Credit
Documents to which Alterra is a party. This Guaranty has been, and each other
Credit Document to which Alterra is a party will be, duly executed and delivered
on behalf of Alterra. This Guaranty constitutes, and each other Credit Document
to which Alterra is a party when executed and delivered will constitute, a
legal, valid and binding obligation of Alterra enforceable against it in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law).

         3.5      NO CONFLICTS.

         Neither the execution and delivery of the Credit Documents, nor the
consummation of the transactions contemplated therein, nor performance of and
compliance with the terms and provisions thereof by Alterra will (a) violate or
conflict with any provision of its articles or certificate of incorporation or
bylaws or other organizational or governing documents of such Person, (b)
violate, contravene or materially conflict with any Requirement of Law or any
other law, regulation (including, without limitation, Regulation U or Regulation
X), order, writ, judgment, injunction, decree or permit applicable to it, (c)
violate, contravene or conflict with contractual provisions of, or cause an
event of default under, any indenture, loan agreement, mortgage, deed of trust,
contract or other agreement or instrument to which it is a party or by which it
may be bound, the violation of which could reasonably be expected to have a
Material Adverse Effect, or (d) result in or require the creation of any Lien
(other than those contemplated in or created in connection with the Credit
Documents) upon or with respect to its properties.

         3.6      NO DEFAULT.

         No Consolidated Party is in default in any respect under any contract,
lease, loan agreement, indenture, mortgage, security agreement or other
agreement or obligation to which it is a party or by which any of its properties
is bound which default could reasonably be expected to have a Material Adverse
Effect. No Default or Event of Default has occurred or exists except as
previously disclosed in writing to the Lenders.

         3.7      OWNERSHIP.

         Each Consolidated Party is the owner of, and has good and marketable
title to, all of its respective assets.

         3.8      LITIGATION.

         There are no actions, suits or legal, equitable, arbitration or
administrative proceedings, pending or, to the knowledge of any Consolidated
Party, threatened against a Consolidated Party which might reasonably be
expected to have a Material Adverse Effect.

         3.9      TAXES.

         Each Consolidated Party has filed, or caused to be filed, all tax
returns (federal, state, local and foreign) required to be filed and paid (a)
all amounts of taxes shown thereon to be due (including interest and penalties)
and (b) all other taxes, fees, assessments and other governmental charges
(including mortgage recording taxes, documentary stamp taxes and intangibles
taxes) owing by it, except for such taxes (i) which are not yet delinquent or
(ii) that are being contested in good faith and by proper proceedings, and
against which adequate reserves are being maintained in accordance with GAAP. No
Consolidated Party is aware of any proposed tax assessments against it or any of
its Subsidiaries which could reasonably be expected to have a Material Adverse
Effect.

         3.10     COMPLIANCE WITH LAW.

         Each Consolidated Party is in compliance with all Requirements of Law
and all other laws, rules, regulations, orders and decrees (including without
limitation Environmental Laws) applicable to it, or to its properties, unless
such failure to comply could not reasonably be expected to have a Material
Adverse Effect.

         3.11     ERISA.

                  (a) During the five-year period prior to the date on which
         this representation is made or deemed made: (i) no ERISA Event has
         occurred, and, to the best knowledge of Alterra, no event or condition
         has occurred or exists as a result of which any ERISA Event could
         reasonably be expected to occur, with respect to any Plan; (ii) no
         "accumulated funding deficiency," as such term is defined in Section
         302 of ERISA and Section 412 of the Code, whether or not waived, has
         occurred with respect to any Plan; (iii) each Plan has been maintained,
         operated, and funded in compliance with its own terms and in material
         compliance with the provisions of ERISA, the Code, and any other
         applicable federal or state laws; and (iv) no lien in favor of the PBGC
         or a Plan has arisen or is reasonably likely to arise on account of any
         Plan.

                  (b) The actuarial present value of all "benefit liabilities"
         (as defined in Section 4001(a)(16) of ERISA), whether or not vested,
         under each Single Employer Plan, as of the last annual valuation date
         prior to the date on which this representation is made or deemed made
         (determined, in each case, in accordance with Financial Accounting


                                       12
<PAGE>   13


         Standards Board Statement 87, utilizing the actuarial assumptions used
         in such Plan's most recent actuarial valuation report), did not exceed
         as of such valuation date the fair market value of the assets of such
         Plan.

                  (c) Neither any Consolidated Party, nor any ERISA Affiliate
         has incurred, or, to the best knowledge of Alterra, could be reasonably
         expected to incur, any withdrawal liability under ERISA to any
         Multiemployer Plan or Multiple Employer Plan. Neither any Consolidated
         Party, nor any ERISA Affiliate would become subject to any withdrawal
         liability under ERISA if any Consolidated Party or any of its
         Subsidiaries or any ERISA Affiliate were to withdraw completely from
         all Multiemployer Plans and Multiple Employer Plans as of the valuation
         date most closely preceding the date on which this representation is
         made or deemed made. Neither any Consolidated Party nor any ERISA
         Affiliate has received any notification that any Multiemployer Plan is
         in reorganization (within the meaning of Section 4241 of ERISA), is
         insolvent (within the meaning of Section 4245 of ERISA), or has been
         terminated (within the meaning of Title IV of ERISA), and no
         Multiemployer Plan is, to the best knowledge of Alterra, reasonably
         expected to be in reorganization, insolvent, or terminated.

                  (d) No prohibited transaction (within the meaning of Section
         406 of ERISA or Section 4975 of the Code) or breach of fiduciary
         responsibility has occurred with respect to a Plan which has subjected
         or may subject any Consolidated Party or any ERISA Affiliate to any
         liability under Sections 406, 409, 502(i), or 502(l) of ERISA or
         Section 4975 of the Code, or under any agreement or other instrument
         pursuant to which any Consolidated Party or any ERISA Affiliate has
         agreed or is required to indemnify any Person against any such
         liability.

                  (e) Neither any Consolidated Party nor any ERISA Affiliates
         has any material liability with respect to "expected post-retirement
         benefit obligations" within the meaning of the Financial Accounting
         Standards Board Statement 106. Each Plan which is a welfare plan (as
         defined in Section 3(1) of ERISA) to which Sections 601-609 of ERISA
         and Section 4980B of the Code apply has been administered in compliance
         in all material respects of such sections.

                  (f) Neither the execution and delivery of this Guaranty nor
         the consummation of the financing transactions contemplated thereunder
         will involve any transaction which is subject to the prohibitions of
         Sections 404, 406 or 407 of ERISA or in connection with which a tax
         could be imposed pursuant to Section 4975 of the Code. The
         representation by Alterra in the preceding sentence is made in reliance
         upon and subject to the accuracy of the Lenders' representation in
         Section 11.16 of the Credit Agreement with respect to their source of
         funds and is subject, in the event that the source of the funds used by
         the Lenders in connection with this transaction is an insurance
         company's general asset account, to the application of Prohibited
         Transaction Class Exemption 95-60, 60 Fed. Reg. 35,925 (1995),
         compliance with the regulations issued under Section 401(c)(1)(A) of
         ERISA, or the issuance of any other prohibited transaction exemption or
         similar relief, to the effect that assets in an insurance company's
         general asset account do not constitute assets of an



                                       13
<PAGE>   14


         "employee benefit plan" within the meaning of Section 3(3) of ERISA of
         a "plan" within the meaning of Section 4975(e)(1) of the Code.

         3.12     SUBSIDIARIES.

         Set forth on Schedule 3.12 is a complete and accurate list of all
Subsidiaries of Alterra.

         3.13     GOVERNMENTAL REGULATIONS, ETC.

                  (a) No Consolidated Party is subject to regulation under the
         Public Utility Holding Company Act of 1935, the Federal Power Act or
         the Investment Company Act of 1940, each as amended. In addition, no
         Consolidated Party is (i) an "investment company" registered or
         required to be registered under the Investment Company Act of 1940, as
         amended, and is not controlled by such a company, or (ii) a "holding
         company", or a "subsidiary company" of a "holding company", or an
         "affiliate" of a "holding company" or of a "subsidiary" of a "holding
         company", within the meaning of the Public Utility Holding Company Act
         of 1935, as amended.

                  (b) No director, executive officer or principal shareholder of
         any Consolidated Party is a director, executive officer or principal
         shareholder of any Lender. For the purposes hereof the terms
         "director", "executive officer" and "principal shareholder" (when used
         with reference to any Lender) have the respective meanings assigned
         thereto in Regulation O issued by the Board of Governors of the Federal
         Reserve System.

                  (c) Each Consolidated Party has obtained and holds in full
         force and effect, all franchises, licenses, permits, certificates,
         authorizations, qualifications, accreditations, easements, rights of
         way and other rights, consents and approvals which are necessary for
         the ownership of its respective Property and to the conduct of its
         respective businesses as presently conducted.

                  (d) No Consolidated Party is in violation of any applicable
         statute, regulation or ordinance of the United States of America, or of
         any state, city, town, municipality, county or any other jurisdiction,
         or of any agency thereof (including without limitation, environmental
         laws and regulations), which violation could reasonably be expected to
         have a Material Adverse Effect.

                  (e) Each Consolidated Party and each of its Subsidiaries is
         current with all material reports and documents, if any, required to be
         filed with any state or federal securities commission or similar agency
         and is in full compliance in all material respects with all applicable
         rules and regulations of such commissions.

         3.14     ENVIRONMENTAL MATTERS.

                  (a) Each of the facilities and properties owned, leased or
         operated by the Consolidated Parties (the "Properties") and all
         operations at the Properties are in compliance with all applicable
         Environmental Laws, and there is no violation of any


                                       14
<PAGE>   15


         Environmental Law with respect to the Properties or the businesses
         operated by the Consolidated Parties (the "Businesses"), and there are
         no conditions relating to the Businesses or Properties that could
         reasonably be expected to give rise to a material liability under any
         applicable Environmental Laws.

                  (b) None of the Properties contains, or has previously
         contained, any Materials of Environmental Concern at, on or under the
         Properties in amounts or concentrations that constitute or constituted
         a violation of, or that could reasonably be expected to give rise to a
         material liability under, Environmental Laws.

                  (c) No Consolidated Party has received any written or verbal
         notice of, or inquiry from any Governmental Authority regarding, any
         violation, alleged violation, non-compliance, liability or potential
         liability regarding environmental matters or compliance with
         Environmental Laws with regard to any of the Properties or the
         Businesses, nor does any Consolidated Party have knowledge or reason to
         believe that any such notice will be received or is being threatened.

                  (d) Materials of Environmental Concern have not been
         transported or disposed of from the Properties, or generated, treated,
         stored or disposed of at, on or under any of the Properties, in each
         case by or on behalf of any Consolidated Party or any of its
         Subsidiaries in violation of, or in a manner that could give rise to
         material liability under, any applicable Environmental Law.

                  (e) No judicial proceeding or governmental or administrative
         action is pending or, to the best knowledge of any Consolidated Party,
         threatened, under any Environmental Law to which any Consolidated Party
         or any of its Subsidiaries is or will be named as a party, nor are
         there any consent decrees or other decrees, consent orders,
         administrative orders or other orders, or other administrative or
         judicial requirements outstanding under any Environmental Law with
         respect to the Consolidated Parties, any of its Subsidiaries, the
         Properties or the Businesses.

                  (f) There has been no release, or threat of release, of
         Materials of Environmental Concern at or from the Properties, or
         arising from or related to the operations (including, without
         limitation, disposal) of any Consolidated Party or any of its
         Subsidiaries in connection with the Properties or otherwise in
         connection with the Businesses, in violation of or in amounts or in a
         manner that could reasonably be expected to give rise to material
         liability under Environmental Laws.

         3.15     INTELLECTUAL PROPERTY.

         Each Consolidated Party owns, or has the legal right to use, all
trademarks, tradenames, copyrights, technology, know-how and processes (the
"Intellectual Property") necessary for each of them to conduct its business as
currently conducted except for those the failure to own or have such legal right
to use could not reasonably be expected to have a Material Adverse Effect.


                                       15
<PAGE>   16


         3.16     SOLVENCY.

         Each Consolidated Party is and, after consummation of the transactions
contemplated by the Credit Agreement and this Guaranty, will be Solvent.

         3.17     DISCLOSURE.

         Neither this Guaranty, the Credit Agreement nor any financial
statements delivered to the Lenders nor any other document, certificate or
statement furnished to the Lenders by or on behalf of any Consolidated Party in
connection with the transactions contemplated hereby contains any untrue
statement of a material fact or omits to state a material fact necessary in
order to make the statements contained therein or herein not misleading.

         3.18     NO BURDENSOME RESTRICTIONS.

         No Consolidated Party nor any of its Subsidiaries is a party to any
agreement or instrument or subject to any other obligation or any charter or
corporate restriction or any provision of any applicable law, rule or regulation
which, individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

         3.19     LABOR MATTERS.

         There are no collective bargaining agreements or Multiemployer Plans
covering the employees of an Consolidated Party or any of its Subsidiaries, and
none of the Consolidated Parties has suffered any strikes, walkouts, work
stoppages or other material labor difficulty within the last five years.

         3.20     YEAR 2000 COMPLIANCE.

         Each Consolidated Party has (i) initiated a review and assessment of
all areas within its and each of its Subsidiaries' business and operations that
could be adversely affected by the "Year 2000 Problem" (that is, the risk that
computer applications used by such Consolidated Party or any of its Subsidiaries
may be unable to recognize and perform properly date-sensitive functions
involving certain dates prior to and any date after December 31, 1999), (ii)
developed a plan and timeline for addressing the Year 2000 Problem on a timely
basis, and (iii) to date, implemented that plan in accordance with the
timetable. Based on the foregoing, Alterra believes that all computer
applications that are material to its and any of its Subsidiaries' business and
operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
(that is, be "Year 2000 compliant"), except to the extent that a failure to do
so could not reasonably be expected to have Material Adverse Effect.

                              AFFIRMATIVE COVENANTS

         Alterra hereby covenants and agrees that, so long as the Credit
Agreement is in effect or any amounts payable thereunder or under any other
Credit Document shall remain outstanding, and until all of the Commitments
thereunder shall have terminated:

         4.1      INFORMATION COVENANTS.

         Alterra will furnish, or cause to be furnished, to the Administrative
Agent and each of the Lenders:

                  (a) Annual Financial Statements. As soon as available, and in
         any event within 90 days after the close of each fiscal year of the
         Consolidated Parties, a consolidated balance sheet and income statement
         of the Consolidated Parties, as of the end of such fiscal year,
         together with related statements of operations and retained earnings
         and of cash flows for such fiscal year, setting forth in comparative
         form figures for the preceding fiscal year, all such financial
         information described above to be in reasonable form and detail and
         audited by independent certified public accountants of recognized
         national standing reasonably acceptable to the Administrative Agent and
         whose opinion shall be to the effect that such financial statements
         have been prepared in accordance with GAAP (except for changes with
         which such accountants concur) and shall not be limited as to the scope
         of the audit or qualified as to the status of the Consolidated Parties
         as a going concern or any other material qualifications or exceptions.

                  (b) Quarterly Financial Statements. As soon as available, and
         in any event within 45 days after the close of each fiscal quarter of
         the Consolidated Parties (other than the fourth fiscal quarter, in
         which case 90 days after the end thereof) a balance sheet and income
         statement of the Consolidated Parties, as of the end of such fiscal
         quarter, together with related statements of cash flows for such fiscal
         quarter, in each case setting forth in comparative form figures for the
         corresponding period of the preceding fiscal year, all such financial
         information described above to be in reasonable form and detail and
         reasonably acceptable to the Administrative Agent, and accompanied by a

         any of its Subsidiaries or any ERISA Affiliate to any liability under
         Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the
         Code, or under any agreement or other instrument pursuant to which any

         agreed or is required to indemnify any person against any such
         liability; or

<PAGE>   28



         Notwithstanding any other provisions herein contained, no provision of
this Guaranty shall require or permit the collection from Alterra of interest in

to pay pursuant to any applicable law. In the event any such interest is
collected, it shall be applied in reduction of Alterra's obligations hereunder,
and the remainder of such excess collected shall be returned to Alterra once
such obligations have been fully satisfied.

         7.3      EXPENSES; INDEMNIFICATION.

                  (a) Alterra agrees to pay on demand all costs and expenses of
         the Administrative Agent in connection with the syndication,
         preparation, execution, delivery, administration, modification, and
         amendment of the Credit Agreement, the other Credit Documents
         (including, without limitation, this Guaranty), and the other documents
         to be delivered thereunder, including, without limitation, the
         reasonable fees and expenses of counsel for the Administrative Agent
         with respect hereto and thereto and with respect to advising the
         Administrative Agent as to its rights and responsibilities under the
         Credit Documents. Alterra further agrees to pay on demand all costs and
         expenses of the Administrative Agent and the Lenders, if any
         (including, without limitation, reasonable attorneys' fees and
         expenses), in connection with the enforcement (whether through
         negotiations, legal proceedings, or otherwise) of the Credit Documents
         (including, without limitation, this Guaranty) and the other documents
         to be delivered pursuant thereto.

                  (b) Alterra agrees to indemnify and hold harmless the
         Administrative Agent and each Lender and each of their Affiliates and
         their respective officers, directors, employees, agents, and advisors
         (each, an "Indemnified Party") from and against any and all claims,
         damages, losses, liabilities, costs, and expenses (including, without
         limitation, reasonable attorneys' fees) that may be incurred by or
         asserted or awarded against any Indemnified Party, in each case arising
         out of or in connection with or by reason of (including, without
         limitation, in connection with any investigation, litigation, or
         proceeding or preparation of defense in connection therewith) the
         Credit Documents (including, without limitation, this Guaranty), any of
         the transactions contemplated herein or the actual or proposed use of
         the proceeds of the Loans (including any of the foregoing arising from
         the negligence of the Indemnified Party), except to the extent such
         claim, damage, loss, liability, cost, or expense is found in a final,
         non-appealable judgment by a court of competent jurisdiction to have
         resulted from such Indemnified Party's gross negligence or willful
         misconduct. In the case of an investigation, litigation or other
         proceeding to which the indemnity in this Section 4.3 applies, such
         indemnity shall be effective whether or not such investigation,
         litigation or proceeding is brought by any of the Credit Parties, their
         respective directors, shareholders or creditors or an Indemnified Party
         or any other Person or any Indemnified Party is otherwise a party
         thereto and whether or not the transactions contemplated hereby are
         consummated. Alterra agrees not to assert any claim against the
         Administrative Agent, any Lender, any of their Affiliates, or any of
         their respective directors, officers, employees, attorneys, agents, and
         advisers, on any theory of liability, for special, indirect,
         consequential, or punitive

         (including, without limitation, this Guaranty), any of the transactions
         contemplated herein or the actual or proposed use of the proceeds of
         the Loans.

                  (c) Without prejudice to the survival of any other agreement
         of Alterra hereunder, the agreements and obligations of Alterra
         contained in this Section 7.3 shall survive the repayment of the
         Guaranteed Obligations.

of the place of payment. If any obligation is unliquidated or unascertained,
such Lender may set-off in any amount estimated by it in good faith to be the
amount of that obligation.

Guaranteed Obligations are fully and indefeasibly paid, performed and discharged
and all Commitments have expired or been terminated. This Guaranty covers the

assignment or transfer by the Administrative Agent or any Lender of any of the
Guaranteed Obligations the legal holder or owner of the Guaranteed Obligations
(or a part thereof or interest therein thus transferred or assigned by the
Administrative Agent or any Lender) shall (except as otherwise stipulated by the
Administrative Agent or any such Lender in its assignment) have and may exercise

Guaranty to the extent of that part of or interest in the Guaranteed Obligations
thus assigned or transferred to said person. Alterra expressly waives notice of
transfer or assignment by the Lenders of the Guaranteed Obligations, or any part

applicable lending office, branch or affiliate other than a connection arising
solely from such Lender having executed, delivered or performed its obligations,
or received payment under or enforced, this Guaranty or any other Credit
Document. If any such non-excluded taxes, levies, imposts, duties, charges,
fees, deductions or withholdings ("Non-Excluded Taxes") are required to be
withheld from any amounts payable to the Administrative Agent or any Lender
under this Guaranty or under any other Credit Document, (A) the amounts so
payable to the Administrative Agent or such Lender shall be increased to the
extent necessary to yield to the Administrative Agent or such Lender (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Guaranty and any
other Credit Document, and (B) as promptly as possible thereafter the Partner
shall send to the Administrative Agent for its own account or for the account of
such Lender, as the case may be, a certified copy of an original official
receipt received by the Partner showing payment thereof. If the Partner fails to
pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails
to remit to the Administrative Agent the required receipts or other required
documentary evidence, the Partner shall indemnify the Administrative Agent and
the Lenders for any incremental taxes, interest or penalties that may become
payable by the Administrative Agent or any Lender as a result of any such
failure. The agreements in this subsection shall survive the termination of this
Guaranty and the other Credit Documents.

         7.13     SEVERABILITY.

         If any provision of this Guaranty is determined to be illegal, invalid
or unenforceable, such provision shall be fully severable and the remaining
provisions shall remain in full force and effect and shall be construed without
giving effect to the illegal, invalid or unenforceable provisions.

         7.14     GOVERNING LAW.

         This Guaranty and the rights and obligations of the parties hereto
shall be construed in accordance with and governed by the laws of the State of
New York.

         7.15     WAIVER OF JURY TRIAL.

         To the extent permitted by law, each of the Administrative Agent and
the Partner hereby irrevocably waives all right to trial by jury in any action,
proceeding or counterclaim arising out of or relating to this Guaranty or the
transactions contemplated hereby.

         7.16     CONSENT TO JURISDICTION.

                  (a) Any legal action or proceeding with respect to this
         Guaranty may be brought in the courts of the State of New York, or of
         the United States for the Southern District of New York, and, by
         execution and delivery of this Guaranty, each of the Partner, the
         Administrative Agent and the Lenders hereby irrevocably accepts for
         itself and in respect of its property, generally and unconditionally,
         the nonexclusive jurisdiction of such courts. Each of the Partner, the
         Administrative Agent and the Lenders further irrevocably consents to
         the service of process out of any of the aforementioned courts in any
         such action or proceeding by the mailing of copies thereof by
         registered or certified mail, postage prepaid, to it at the address set
         out for notices pursuant to Section 7.11, such service to become
         effective three (3) days after such mailing. Nothing herein shall
         affect the right of the Administrative Agent or any Lender to (i) serve
         process or to commence legal proceedings in any other manner permitted
         by law or (ii) commence legal proceedings, exercise rights or otherwise
         proceed against the Collateral in any other jurisdictions as permitted
         by law or as deemed necessary or appropriate by the Administrative
         Agent or any Lender. Nothing herein shall affect the rights of Alterra
         to serve process or to commence legal proceedings in any other manner
         permitted by law.

                  (b) The Partner hereby irrevocably and unconditionally waives,
         to the fullest extent it may legally and effectively do so, any
         objection which it may now or hereafter have to the laying of venue of
         any suit, action or proceeding arising out of or relating to this
         Guaranty in the courts referred to in Section 7.16(a). Each of the
         parties hereto hereby further irrevocably waives and agrees not to
         plead or claim in any such court that any such action or proceeding
         brought in any such court has been brought in an inconvenient forum.

                  (c) Each party to this Guaranty irrevocably consents to
         service of process in the manner provided for notices in Section 7.11.
         Nothing in this Guaranty will affect the right of any party to this
         Guaranty to serve process in any other manner permitted by law.

         7.17     HEADINGS.

         The headings in this instrument are for convenience of reference only
and shall not limit or otherwise affect the meaning of any provisions hereof.

in the Credit Agreement (as defined below) shall be used herein as therein
defined. Certain terms used herein are defined in section 1 hereof.

         (2)   This Guaranty is made pursuant to the Master Construction Line of
Credit Agreement, dated as of the date hereof (herein, as amended or otherwise
modified, restated or replaced from time to time, the "CREDIT AGREEMENT"), among
Third Party Investors I, LLC, a Delaware limited liability company (herein,
together with its successors and assigns, the "BORROWER"), the financial
institutions named as lenders therein (herein, together with their successors
and assigns, the "LENDERS"), and the Administrative Agent, providing, among
other things, for loans or advances or other extensions of credit to or for the
benefit of the Borrower of up to $75,000,000, with such loans or advances being

other securities issued in exchange therefor or in replacement thereof).

         (3)   The Borrower may from time to time be party to one or more
Designated Hedge Agreements (as defined in the Credit Agreement) and other

Agreement.

         (7)   It is a condition to the making of Loans under the Credit
Agreement that the Guarantor shall have executed and delivered this Guaranty.

         (8)   The Guarantor will obtain benefits from the incurrence of the
Credit Document Obligations and the Designated Hedge Document Obligations (as
such terms are hereafter defined) and, accordingly, desires to execute this
Guaranty in order to satisfy the condition described in the preceding paragraph
and to induce the Creditors to extend the Credit Document Obligations and the
Designated Hedge Document Obligations.

demand by the Administrative Agent, will make payment to the Administrative
Agent, for the account of the Creditors, of all such obligations not so

Borrower or other person, against any security for all or any portion of the
Guaranteed Obligations, or under any other guaranty covering all or any portion
of the Guaranteed Obligations.

         (F)   PAYMENTS BY GUARANTOR. All payments by the Guarantor under this
Guaranty shall be made to the Administrative Agent, for the benefit of the
Creditors, in such currency and otherwise in such manner as is provided in the

received by the Guarantor as trustee for the Creditors and be paid over to the
Administrative Agent, for the benefit of the Creditors, on account of the
Indebtedness of the Borrower to the Creditors, but without affecting or
impairing in any manner the liability of the Guarantor under the other
provisions of this Guaranty. Prior to the transfer by the Guarantor of any note
or negotiable instrument evidencing any Subordinated Obligation of the Borrower
to the Guarantor, the Guarantor shall mark such note or negotiable instrument
with a legend that the same is subject to this subordination.

         (b)   If and to the extent that the Guarantor makes any payment to the
Administrative Agent or any other Creditor or to any other person pursuant to or

subordinate to the prior termination of the Total Commitment and indefeasible

         or other surety.

         5     LIMITATION ON OBLIGATIONS OF GUARANTOR. (a) Notwithstanding
anything to the contrary contained in this Guaranty, no Loans which have been
prepaid or repaid and then re-borrowed shall be covered by the Guarantor's
guaranty and other obligations under section 2 of this Guaranty unless such
re-borrowing is consented to in writing by the Guarantor, PROVIDED that this
clause shall not apply to the prepayment or repayment, and contemporaneous
re-borrowing, of any Loans effected solely to accommodate the joinder in the
Credit Agreement of the additional Lender providing the Incremental Commitment,
as contemplated by section 2.1(f) of the Credit Agreement, and no (i) increase
in the maximum aggregate principal amount of the Loans above $75,000,000; (ii)
increases in the interest rate or rates applicable to the Loan, other than
fluctuations in the Prime Rate or Applicable LIBOR Rate or a change to the
Default Rate pursuant to the terms of the Notes or Credit Agreement; or (iii)
changes in the maturity dates of the Loans, unless extended pursuant to Section
2.7 of the Credit Agreement or unless accelerated by the Administrative Agent
pursuant to the terms of the Credit Agreement, shall be binding upon the
Guarantor for purposes of this Guaranty unless such increases or changes are
consented to in writing by the Guarantor.

         (b)   Notwithstanding anything to the contrary contained in this
Guaranty, the Guarantor's guaranty and other obligations under section 2 of this
Guaranty shall be limited to the sum of:

               (i)    100% of the Credit Document Obligations; and

               (ii)   such portion, not in excess of 100%, of the Designated
         Hedge Document Obligations, as the Administrative Agent determines will
         not result in the Guarantor's guaranty and other obligations under
         section 2 of this Guaranty in respect of all of the Guaranteed
         Obligations, exclusive of interest on the Notes issued by the Borrower
         under the Credit Agreement, exceeding 85% of the result obtained by
         subtracting from the Total Project Costs the sum of (x) the then
         outstanding principal balance of all loans made by the Guarantor to the
         Borrower the proceeds of which are actually applied to the Total
         Project Costs, plus (y) all capital contributions made by the Guarantor
         to the Borrower pursuant to the terms of the Company Equity Documents
         and Company Capitalization Documents.



                                       12

<PAGE>   13

In no event shall the provisions of this section 5 limit, impair or otherwise
affect the ability of the Administrative Agent to apply monies or other proceeds
of enforcement in accordance with section 10.3 of the Credit Agreement.

         6     WAIVERS.  The Guarantor unconditionally waives, to the maximum
extent permitted under any applicable law now or hereafter in effect, insofar as
its obligations under this Guaranty are concerned, (i) notice of any of the
matters referred to in section 4 unless notice is specifically required under
the Credit Documents, (ii) all notices required by statute, rule of law or
otherwise to preserve any rights against the Guarantor hereunder, including,
without limitation, any demand, presentment, proof or notice of dishonor or
non-payment of any Guaranteed Obligation, notice of acceptance of this Guaranty,
notice of the incurrence of any Guaranteed Obligation, notice of any failure on
the part of the Borrower or any other person to perform or comply with any term
or provision of the Credit Agreement, any other Guaranteed Document or any other
agreement or instrument to which the Borrower or any other person is a party, or
notice of the commencement of any proceeding against any other person or any of
its property or assets unless notice is specifically required under the Credit
Documents, (iii) any right to the enforcement, assertion or exercise against the
Borrower or against any other person or any collateral of any right, power or
remedy under or in respect of the Credit Agreement, the other Guaranteed
Documents or any other agreement or instrument, (iv) any requirement that the
Guarantor be joined as a party to any proceedings against the Borrower or any
other person for the enforcement of any term or provision of the Credit
Agreement, the other Guaranteed Documents or any other agreement or instrument,
and (v) the provisions of Nev. Rev. Stat. 40.430, the "one action rule" and any
amendments or successor statutes thereto, and the Guarantor understands and
acknowledges that demand upon and an action against the Guarantor to pay the
indebtedness, if secured by a mortgage or lien upon real property, may, at the
sole and absolute option of the Collateral Agent, be initiated against the
Guarantor as a separate and independent action apart from the action initiated
to recover the indebtedness or obligation secured by said mortgage or lien upon
real property.

         7     SUBROGATION RIGHTS. Until such time as the Guaranteed Obligations
have been paid in full in cash and otherwise fully performed and the Total
Commitment under the Credit Agreement has been terminated, the Guarantor hereby
agrees not to assert any rights of subrogation which it may at any time
otherwise have as a result of this Guaranty (whether contractual, under section
509 of the Bankruptcy Code, or otherwise) to the claims of the Administrative
Agent and/or the other Creditors against the Borrower or any other guarantor of
or surety for the Guaranteed Obligations and all contractual, statutory or
common law rights of reimbursement, contribution or indemnity from the Borrower
or any other guarantor which it may at any time otherwise have as a result of
this Guaranty.

         8     SEPARATE ACTIONS. A separate action or actions may be brought and
prosecuted against the Guarantor whether or not action is brought against any
other person, including the Borrower, and whether or not any other person,
including the Borrower be joined in any such action or actions.

         9     GUARANTOR FAMILIAR WITH BORROWER'S AFFAIRS, ETC. The Guarantor
confirms that an executed (or conformed) copy of each of the Credit Documents
has been made available to its principal executive officers, that such officers
are familiar with the contents thereof and of this Guaranty, and that it has
executed and delivered this Guaranty after reviewing the terms and conditions of
the Credit Agreement, the other Credit Documents and this Guaranty and such
other information as it has deemed appropriate in order to make its own credit
analysis and decision to execute and deliver this Guaranty. The Guarantor
confirms that it has made its own independent investigation with respect to the
creditworthiness of the Borrower and is not executing and delivering this
Guaranty in reliance on any representation or warranty by the Administrative
Agent or any other Creditor or any other person acting on behalf of the
Administrative Agent or any other Creditor as to such creditworthiness. The
Guarantor expressly assumes all responsibilities to remain informed of the
financial condition of the Borrower and any circumstances affecting (i) the
Borrower's ability to perform its obligations under the Credit Agreement and the
other Guaranteed Documents to which it is a party, or (ii) any collateral
securing, or any other guaranty for, all or any part of the Borrower's payment
and performance obligations thereunder; and the Guarantor further agrees that
the Administrative Agent and the other Creditors shall have no duty to advise
the Guarantor of information known to them regarding such circumstances or the
risks the Guarantor undertakes in this Guaranty.

         10    COVENANT NOT TO CAUSE EVENTS OF DEFAULT UNDER CREDIT AGREEMENT,
ETC. The Guarantor covenants and agrees that on and after the date hereof and
until this Guaranty is terminated in accordance with section 25 hereof,


                                       13

<PAGE>   14

the Guarantor shall take, or will refrain from taking, as the case may be, all
actions that are necessary to be taken or not taken so that no violation of any
provision, covenant or agreement contained in section 8 or 9 of the Credit
Agreement, and so that no Default or Event of Default, is caused by the actions
of the Guarantor or any of its Subsidiaries.

         11    REPRESENTATIONS AND WARRANTIES. The Guarantor represents and
warrants to the Administrative Agent and each of the other Creditors that:

               (a)    ORGANIZATION AND CORPORATE POWER AND AUTHORITY. The
         Guarantor is a duly organized and validly existing corporation, in good
         standing under the laws of the jurisdiction of its formation and has
         the corporate power and authority to own its property and assets and to
         transact the business in which it is engaged and presently proposes to
         engage. The Guarantor has the corporate power and authority to execute,
         deliver and carry out the terms and provisions of the Credit Documents
         to which it is party and has taken all necessary corporate action to
         authorize the execution, delivery and performance of the Credit
         Documents to which it is party.

               (b)    CREDIT DOCUMENTS. The Guarantor has duly executed and
         delivered each Credit Document to which it is party and each Credit
         Document to which it is party constitutes the legal, valid and binding
         agreement or obligation of the Guarantor enforceable in accordance with
         its terms, except to the extent that the enforceability thereof may be
         limited by applicable bankruptcy, insolvency, reorganization,
         moratorium or other similar laws generally affecting creditors' rights
         and by equitable principles (regardless of whether enforcement is
         sought in equity or at law).

               (c)    NO CONFLICTS, ETC. Neither the execution, delivery and
         performance by the Guarantor of the Credit Documents to which the
         Guarantor is party nor compliance with the terms and provisions thereof
         (i) will contravene any provision of any law, statute, rule,
         regulation, order, writ, injunction or decree of any court or
         governmental instrumentality applicable to the Guarantor or its
         properties and assets, (ii) will conflict with or result in any breach
         of, any of the terms, covenants, conditions or provisions of, or
         constitute a default under, or result in the creation or imposition of
         (or the obligation to create or impose) any Lien (other than any Lien
         created pursuant to the Credit Documents) upon any of the property or
         assets of the Guarantor pursuant to the terms of any material
         promissory note, bond, debenture, indenture, mortgage, deed of trust,
         credit or loan agreement, or any other material agreement or other
         instrument, to which the Guarantor is a party or by which it or any of
         its property or assets are bound or to which it may be subject, or
         (iii) will violate any provision of the certificate or articles of
         incorporation, code of regulations or by-laws, or other charter or
         organizational documents of the Guarantor.

               (d)    NO GOVERNMENTAL APPROVALS, ETC. No order, consent,
         approval, license, authorization, or validation of, or filing,
         recording or registration with, or exemption by, any foreign or
         domestic governmental or public body or authority, or any subdivision
         thereof, is required to authorize or is required as a condition to (i)
         the execution, delivery and performance by the Guarantor of any Credit
         Document to which it is a party, or (ii) the legality, validity,
         binding effect or enforceability of any Credit Document to which the
         Guarantor is a party, other than filings and recordings necessary to
         establish or perfect any security interests or other Liens created
         pursuant to the Credit Documents.

               (e)    LITIGATION. There are no actions, suits or proceedings
         pending or, to, the knowledge of the Guarantor, threatened with respect
         to the Guarantor which question the validity or enforceability of any
         of the Credit Documents to which the Guarantor is a party, or of any
         action to be taken by the Guarantor pursuant to any of the Credit
         Documents to which it is a party.

               (f)    FINANCIAL STATEMENTS, ETC. The Guarantor has furnished to
         the Lenders and the Administrative Agent complete and correct copies of
         (1) the audited consolidated balance sheet of the Guarantor and its
         consolidated subsidiaries as of December 31, 1997 and December 31,
         1998, and the related audited consolidated statements of income,
         shareholders' equity, and cash flows for the fiscal years then ended,
         accompanied by the unqualified report thereon of the Guarantor's
         independent accountants; and (2) the unaudited condensed consolidated
         balance sheets of the Guarantor and its consolidated subsidiaries as of
         June


                                       15
<PAGE>   15

         30, 1999, and the related unaudited condensed consolidated
         statements of income and of cash flows of the Guarantor and its
         consolidated subsidiaries for the fiscal quarter or quarters then
         ended, as contained in the Form 10-Q Quarterly Report of the Guarantor
         filed with the SEC. All such financial statements have been prepared in
         accordance with GAAP, consistently applied (except as stated therein),
         and fairly present the financial position of the Guarantor and its
         consolidated subsidiaries as of the respective dates indicated and the
         consolidated results of their operations and cash flows for the
         respective periods indicated, subject in the case of any such financial
         statements which are unaudited, to the absence of footnotes and to
         normal year-end or audit adjustments which the Guarantor reasonably
         believes will not involve a Material Adverse Effect.

               (g)    NO MATERIAL ADVERSE CHANGE. Since December 31, 1998, there
         has been no change in the condition, business or affairs of the
         Guarantor and its Subsidiaries taken as a whole, or their properties
         and assets considered as an entirety, except for changes, which, in the
         aggregate, have not had or could not reasonably be expected to have, a
         Material Adverse Effect.

               (h)    ANNUAL REPORT ON FORM 10-K. The Guarantor has delivered or
         caused to be delivered to the Lenders prior to the Effective Date a
         copy of the Guarantor's Report on Form 10-K as filed (without Exhibits)
         with the SEC for its fiscal year ended December 31, 1998, which
         contains a general description of the business and affairs of the
         Guarantor and its Subsidiaries.

               (i)    CONFIDENTIAL INFORMATION MEMORANDUM; FINANCIAL
          PROJECTIONS. The Guarantor has delivered or caused to be delivered to
         the Lenders prior to the Effective Date (1) a confidential information
         brochure dated April 1999, as supplemented by a Summary of Terms and
         Conditions distributed May 28, 1999, prepared by the Administrative
         Agent (with assistance from the Guarantor) which contains information
         with respect to the business, properties and operations of the
         Guarantor and its Subsidiaries (the "CONFIDENTIAL INFORMATION
         MEMORANDUM"), and (2) financial projections prepared by management of
         the Guarantor for (x) the Guarantor and its Subsidiaries for the fiscal
         years 1999-2001, and (y) the Borrower, which are included as part of
         the Confidential Information Memorandum (the "FINANCIAL PROJECTIONS").
         The Financial Projections were prepared on behalf of the Guarantor in
         good faith after taking into account historical levels of business
         activity of the Guarantor and its Subsidiaries, the particular Projects
         to be developed for the Borrower, known trends, including general
         economic trends, and all other information, assumptions and estimates
         considered by management of the Guarantor and its Subsidiaries to be
         pertinent thereto; PROVIDED, that no representation or warranty is made
         as to the impact of future general economic conditions or as to whether
         the Guarantor's or the Borrower's projected consolidated results as set
         forth in the Financial Projections will actually be realized. No facts
         are known to the Guarantor at the date hereof which, if reflected in
         the Financial Projections, would result in a material adverse change in
         the assets, liabilities, results of operations or cash flows reflected
         therein.

               (j)    CONSIDERATION FOR GUARANTY; SOLVENCY. The Guarantor has
         received consideration which is the reasonable equivalent value of the
         obligations and liabilities that the Guarantor has incurred to the
         Administrative Agent and the other Creditors under this Guaranty and
         the other Credit Documents to which the Guarantor is a party. The
         Guarantor has capital sufficient to carry on its business and
         transactions and all business and transactions in which it is about to
         engage and is solvent and able to pay its debts as they mature. The
         Guarantor owns property having a value, both at fair valuation and at
         present fair salable value, greater than the amount required to pay its
         debts. The Guarantor is not entering into this Guaranty or any other
         Credit Documents to which it is a party with the intent to hinder,
         delay or defraud its creditors.

               (k)    TAX RETURNS AND PAYMENTS. Each of the Guarantor and each
         of its Subsidiaries has filed all federal income tax returns and all
         other material tax returns, domestic and foreign, required to be filed
         by it and has paid all material taxes and assessments payable by it
         which have become due, other than those not yet delinquent and except
         for those contested in good faith. The Guarantor and each of its
         Subsidiaries has established on its books such charges, accruals and
         reserves in respect of taxes, assessments, fees and other governmental
         charges for all fiscal periods as are required by GAAP. The Guarantor
         knows of no proposed assessment for additional federal, foreign or
         state taxes for any period, or of any basis therefor, which,
         individually or in the aggregate, taking into account such charges,
         accruals and reserves in respect thereof as the Guarantor and its
         Subsidiaries have made, could reasonably be expected to have a Material
         Adverse Effect.

               (l)    COMPLIANCE WITH ERISA. Compliance by the Guarantor with
         the provisions hereof and the making of the Loans contemplated by the
         Credit Documents will not involve any prohibited transaction within the
         meaning of ERISA or section 4975 of the Code. The Guarantor and each of
         its Subsidiaries, (i) has fulfilled all obligations under minimum
         funding standards of ERISA and the Code with respect to each Plan that
         is not a Multiemployer Plan or a Multiple Employer Plan, (ii) has
         satisfied all respective contribution obligations in respect of each
         Multiemployer Plan and each Multiple Employer Plan, (A) is in
         compliance in all material respects with all other applicable
         provisions of ERISA and the Code with respect to each Plan, each
         Multiemployer Plan and each Multiple Employer Plan, and (iii) has not
         incurred any liability under the Title IV of ERISA to the PBGC with
         respect to any Plan, any Multiemployer Plan, any Multiple Employer
         Plan, or any trust established thereunder. No Plan or trust created
         thereunder has been terminated, and there have been no Reportable
         Events, with respect to any Plan or trust created thereunder or with
         respect to any Multiemployer Plan or Multiple Employer Plan, which
         termination or Reportable Event will or could result in the termination
         of such Plan, Multiemployer Plan or Multiple Employer Plan and give
         rise to a material liability of the Guarantor or any ERISA Affiliate in
         respect thereof. Neither the Guarantor nor any ERISA Affiliate is at
         the date hereof, or has been at any time within the two years preceding
         the date hereof, an employer required to contribute to any
         Multiemployer Plan or Multiple Employer Plan, or a "contributing
         sponsor" (as such term is defined in section 4001 of ERISA) in any
         Multiemployer Plan or Multiple Employer Plan. Neither the Guarantor nor
         any ERISA Affiliate has any contingent liability with respect to any
         post-retirement "welfare benefit plan" (as such term is defined in
         ERISA) except as has been disclosed to the Lenders in writing.

               (m)    INVESTMENT COMPANY ACT, ETC. Neither the Guarantor nor any
         of its Subsidiaries is subject to regulation with respect to the
         creation or incurrence of Indebtedness under the Investment Company Act
         of 1940, as amended, the Interstate Commerce Act, as amended, the
         Federal Power Act, as amended, the Public Utility Holding Company Act
         of 1935, as amended, or any applicable state public utility law.

               (n)    YEAR 2000 COMPUTER MATTERS. (i) The Guarantor and its
         Subsidiaries have (A) conducted a comprehensive review and assessment
         of all areas of their business that could be adversely affected by the
         "Y2K ISSUE" (that is, the risk that computer applications used by the
         Guarantor and its Subsidiaries may be unable to recognize and perform
         properly date-sensitive functions involving certain dates prior to and
         any date after December 31, 1999), which review and assessment has
         included, without limitation written inquiry of each of the Guarantor's
         and its Subsidiaries' key suppliers, vendors and customers with whom
         there is regular electronic communication via access to computer
         networks or systems, (B) developed a detailed plan and timeline for
         addressing the Y2K issue, including linkages with, and programming
         changes to be made by, key suppliers, vendors and customers, on a
         timely basis, and (C) to date, implemented that plan in accordance with
         that timetable.

               (ii)   Based on such review and program, (A) the Guarantor
         reasonably believes that the Y2K issue is not reasonably likely to have
         a Material Adverse Effect, (B) the Guarantor reasonably anticipates
         that all computer applications that are material to its business and
         the business of its Subsidiaries will on a timely basis be able to
         perform properly date-sensitive functions for all dates before and
         after January 1, 2000 (i.e., be "Y2K COMPLIANT"), and (C) the Guarantor
         reasonably believes that each of such key suppliers, vendors and
         customers will on a timely basis be Y2K compliant in all material
         respects which affect the Guarantor or any of its Subsidiaries.

               (o)    TRUE AND COMPLETE DISCLOSURE. All factual information
         (taken as a whole) heretofore or contemporaneously furnished by or on
         behalf of the Guarantor or any of its Subsidiaries in writing to the
         Administrative Agent or any Lender for purposes of or in connection
         with this Guaranty or any transaction contemplated herein, other than
         the Financial Projections (as to which representations are made only as
         provided in section 11(i) hereof), is, and all other such factual
         information (taken as a whole) hereafter furnished by or on behalf of
         such person in writing to any Lender will be, true and accurate in all
         material respects on the date as of which such information is dated or
         certified and not incomplete by omitting to state any material fact
         necessary to make such information (taken as a whole) not misleading at
         such time in light of the circumstances under which such information
         was provided, except that any such future information consisting of
         financial projections

                                       16


<PAGE>   17

         prepared by management of the Guarantor is only represented herein as
         being based on good faith estimates and assumptions believed by such
         persons to be reasonable at the time made, it being recognized by the
         Lenders that such projections as to future events are not to be viewed
         as facts and that actual results during the period or periods covered
         by any such projections may differ materially from the projected
         results. As of the date hereof, there is no fact known to the Guarantor
         or any of its Subsidiaries which has, or could reasonably be expected
         to have, a Material Adverse Effect which has not theretofore been
         disclosed in writing to the Lenders.

         12.   AFFIRMATIVE COVENANTS. The Guarantor covenants and agrees that on
and after the date hereof and until this Guaranty is terminated in accordance
with section 25 hereof:

               (a)    REPORTING REQUIREMENTS. The Guarantor will furnish to each
         Lender and the Administrative Agent:

                      (i)    ANNUAL CONSOLIDATED FINANCIAL STATEMENTS. As soon
               as available and in any event within 90 days after the close
               of each fiscal year of the Guarantor, the consolidated balance
               sheets of the Guarantor and its consolidated Subsidiaries as
               at the end of such fiscal year and the related consolidated
               statements of income, of stockholder's equity and of cash
               flows for such fiscal year, in each case setting forth
               comparative figures for the preceding fiscal year, all in
               reasonable detail and accompanied by the opinion with respect
               to such consolidated financial statements of independent
               public accountants of recognized national standing selected by
               the Guarantor, which opinion shall be unqualified and shall
               (A) state that such accountants audited such consolidated
               financial statements in accordance with generally accepted
               auditing standards, that such accountants believe that such
               audit provides a reasonable basis for their opinion, and that
               in their opinion such consolidated financial statements
               present fairly, in all material respects, the consolidated
               financial position of the Guarantor and its consolidated
               subsidiaries as at the end of such fiscal year and the
               consolidated results of their operations and cash flows for
               such fiscal year in conformity with generally accepted
               accounting principles, or (B) contain such statements as are
               customarily included in unqualified reports of independent
               accountants in conformity with the recommendations and
               requirements of the American Institute of Certified Public
               Accountants (or any successor organization).

                      (ii)   QUARTERLY CONSOLIDATED FINANCIAL STATEMENTS. As
               soon as available and in any event within 45 days after the
               close of each of the first three quarterly accounting periods
               in each fiscal year of the Guarantor and within 90 days after
               the close of the last quarterly accounting period in each
               fiscal year of the Guarantor, the unaudited condensed
               consolidated balance sheets of the Guarantor and its
               consolidated Subsidiaries as at the end of such quarterly
               period and the related unaudited condensed consolidated and
               consolidating statements of income and of cash flows for such
               quarterly period and for the fiscal year to date, and setting
               forth, in the case of such unaudited consolidated statements
               of income and of cash flows, comparative figures for the
               related periods in the prior fiscal year, and which
               consolidated financial statements shall be certified on behalf
               of the Guarantor by the Chief Financial Officer or other
               Authorized Officer of the Guarantor, subject to changes
               resulting from normal year-end or audit adjustments.

                      (iii)  OFFICER'S COMPLIANCE CERTIFICATES. At the time
               of the delivery of the financial statements provided for in
               sections 12(a)(i) and (ii), a certificate on behalf of the
               Guarantor of the Chief Financial Officer or other Authorized
               Officer of the Guarantor to the effect that, to the best
               knowledge of the Guarantor, no Default or Event of Default
               (including, without limitation pursuant to section 10.1 of the
               Credit Agreement) exists or, if any Default or Event of
               Default does exist, specifying the nature and extent thereof,
               and which certificate shall set forth the calculations
               required to establish compliance with the provisions of
               sections 13(b), (c), (d) and (e) of this Guaranty.

                      (iv)   NOTICE OF DEFAULT OR LITIGATION, ETC. Promptly,
               and in any event within three Business Days, in the case of
               clause (A) below, or five Business Days, in the case of clause
               (B) below, after the Guarantor or any of its Subsidiaries
               obtains knowledge thereof, notice of


                                       17
<PAGE>   18
                           (a)  the occurrence of any event which
                    constitutes a Default or Event of Default, which notice
                    shall specify the nature thereof, the period of existence
                    thereof and what action the Guarantor proposes to take with
                    respect thereto, and

                           (b)  any litigation or governmental or
                    regulatory proceeding pending against the Guarantor, or any
                    of its Subsidiaries, or the Borrower, which is likely to
                    have a Material Adverse Effect, or a material adverse effect
                    on the ability of the Guarantor or the Borrower to perform
                    its obligations hereunder or under any other Credit
                    Document.

                    (v)    AUDITORS' INTERNAL CONTROL COMMENT LETTERS, ETC.
               Promptly upon receipt thereof, a copy of each letter or
               memorandum commenting on internal accounting controls or
               financial reporting practices or policies which is submitted
               to the Guarantor by its independent accountants in connection
               with any annual audit made by them of the books of the
               Guarantor.

                    (vi)   SEC REPORTS AND REGISTRATION STATEMENTS. Promptly
               upon transmission thereof or other filing with the SEC, copies
               of all annual, quarterly or current reports that the Guarantor
               or any of its Subsidiaries files with the SEC. In addition,
               the Guarantor shall cause LiveEdgar(TM) or another third party
               service bureau regularly offering such "watch" services to
               promptly notify via e-mail a representative designated by the
               Administrative Agent of all registration statements filed with
               the SEC by the Guarantor or any of its Subsidiaries.

                    (vii)  OTHER  INFORMATION. With reasonable promptness, such
               other information or documents (financial or otherwise) relating
               to the Guarantor or any of its Subsidiaries as any Creditor may
               reasonably request from time to time.

               (b)  BOOKS, RECORDS AND INSPECTIONS. The Guarantor will, and will
         cause each of its Subsidiaries to, (i) keep proper books of record
         and account, in which full and correct entries shall be made of all
         financial transactions and the assets and business of the Guarantor or
         such Subsidiaries, as the case may be, in accordance with GAAP; and
         (ii) permit, upon at least five Business Days' notice to the Chief
         Financial Officer or any other Authorized Officer of the Guarantor,
         officers and designated representatives of the Administrative Agent or
         any of the other Creditors to visit and inspect any of the properties
         or assets of the Guarantor and any of its Subsidiaries in whomsoever's
         possession (but only to the extent the Guarantor or such Subsidiary has
         the right to do so to the extent in the possession of another person),
         to examine the books of account of the Guarantor and any of its
         Subsidiaries and to make copies thereof and take extracts therefrom,
         and to discuss the affairs, finances and accounts of the Guarantor and
         of any of its Subsidiaries with, and be advised as to the same by, its
         and their officers and independent accountants and independent
         actuaries, if any, all at such reasonable times and intervals and to
         such reasonable extent as the Administrative Agent or any of the other
         Creditors may request.

               (c)   INSURANCE. The Guarantor will, and will cause each of its
         Subsidiaries to, (i) maintain insurance coverage by such insurers and
         in such forms and amounts and against such risks as are generally
         consistent with the insurance coverage maintained by the Guarantor and
         its Subsidiaries at the date hereof, and (ii) forthwith upon any
         Creditor's written request, furnish to such Creditor such information
         about such insurance as such Creditor may from time to time reasonably
         request, which information shall be prepared in form and detail
         satisfactory to such Creditor and certified by an Authorized Officer of
         the Guarantor.

               (d)   PAYMENT OF TAXES AND CLAIMS. The Guarantor will pay and
         discharge, and will cause each of its Subsidiaries to pay and
         discharge, all taxes, assessments and governmental charges or levies
         imposed upon it or upon its income or profits, or upon any properties
         belonging to it, prior to the date on which penalties attach thereto,
         and all lawful claims which, if unpaid, might become a Lien or charge
         upon any properties of the Guarantor or any of its Subsidiaries;
         PROVIDED that neither the Guarantor nor any of its Subsidiaries shall
         be required to pay any such tax, assessment, charge, levy or claim
         which is being contested in good faith and by proper proceedings if it
         has maintained adequate reserves with respect thereto in accordance
         with GAAP; and PROVIDED, FURTHER, that the Guarantor will not be
         considered to be in default of any of the provisions of this


                                       18

<PAGE>   19

         sentence if the Guarantor or any Subsidiary fails to pay any such
         amount which, individually or in the aggregate, is immaterial to the
         Guarantor and its Subsidiaries considered as an entirety.

               (e)    CORPORATE FRANCHISES. The Guarantor will do, and will
         cause  each of its Subsidiaries to do, or cause to be done, all things
         necessary to preserve and keep in full force and effect its corporate
         or other organizational existence, rights, authority and franchises,
         PROVIDED that nothing in this section 12(e) shall be deemed to prohibit
         (i) any transaction permitted by section 13(a); (ii) the termination of
         existence of any Subsidiary if (1) the Guarantor determines that such
         termination is in its best interest and (2) such termination is not
         adverse in any material respect to the Lenders; or (iii) the loss of
         any rights, authorities or franchises if the loss thereof, in the
         aggregate, could not reasonably be expected to have a Material Adverse
         Effect.

               (f)    GOOD REPAIR. The Guarantor will, and will cause each of
         its Subsidiaries to, ensure that its material properties and equipment
         used or useful in its business in whomsoever's possession they may be,
         are kept in good repair, working order and condition, normal wear and
         tear excepted, and that from time to time there are made in such
         properties and equipment all needful and proper repairs, renewals,
         replacements, extensions, additions, betterments and improvements,
         thereto, to the extent and in the manner customary for companies in
         similar businesses.

               (g)    COMPLIANCE WITH STATUTES, ETC. The Guarantor will, and
         will cause each of its Subsidiaries to, comply, in all material
         respects, with all applicable statutes, regulations and orders of, and
         all applicable restrictions imposed by, all governmental bodies,
         domestic or foreign, in respect of the conduct of its business and the
         ownership of its property (including, without limitation, all
         Environmental Laws), other than those (i) being contested in good faith
         by appropriate proceedings, as to which adequate reserves are
         established to the extent required under GAAP, and (ii) the
         noncompliance with which would not have, and which would not be
         reasonably expected to have, a Material Adverse Effect on the
         Guarantor.

               (h)    INFORMATION CONCERNING DEVCO. The Guarantor will furnish
         to the Lenders, promptly after the same become available, copies of all
         quarterly and annual financial statements of Devco, together with a
         certificate on behalf of the Guarantor of the Chief Financial Officer
         or other authorized officer of the Guarantor dated as of the date of
         any such financial statements, certifying to the best knowledge of the
         Guarantor, the extent of the equity interests in Devco and each joint
         venture arrangement in which Devco participates held by persons who are
         not Affiliates of the Guarantor and the outstanding amount of
         Indebtedness of Devco or such joint venture which has been guaranteed
         by the Guarantor, together with such information as may be reasonably
         requested by the Collateral Agent related to such financial statements.

               (i)    SENIOR DEBT. The Guarantor will at all times ensure that
         (i) the claims of the Creditors hereunder will not be subordinate to,
         and will in all respects rank prior to the claims of every senior
         unsecured creditor of the Guarantor, and (ii) any Indebtedness
         subordinated in any manner to the claims of any other senior secured or
         unsecured creditor of the Guarantor will be subordinated in like manner
         to such claims of the Creditors.

         prior written consent of the Administrative Agent (acting on the
         instruction of the Required Lenders), the Guarantor shall not

         transfer or lease substantially all of its assets in a single
         transaction or series of transactions to any person, or permit any
         person or persons acting in concert, together with any Affiliates
         thereof, to in the aggregate, directly or indirectly, control or own
         (beneficially or otherwise) more than 50% (by number of shares) of the
         issued and outstanding stock of the Guarantor (any such transaction a
         "CHANGE OF CONTROL"); provided that a Change of Control of the
         Guarantor resulting from (A) a sale, issuance or transfer of any stock
         in the Guarantor, of (B) a merger, consolidation, reorganization or
         other business combination involving the Guarantor shall be permitted
         (any such transaction a "PERMITTED TRANSACTION") PROVIDED that

               Net Worth of the Guarantor or its successor entity, on a
               consolidated basis, is at least equal to the Consolidated Net
               Worth of the Guarantor immediately prior to such Permitted
               Transaction, and after the Permitted Transaction all other
               financial covenants contained herein shall remain satisfied;

                      (2)    the Guarantor or its successor entity (or the
               Guarantor's or such successor entity's parent corporation) is, at
               the time of or immediately after such transaction, a publicly
               held corporation;

                      (3)    the successor entity (if other than the Guarantor)
               expressly assumes in writing all of the Guarantor's past, current
               and future obligations and liabilities under  this Guaranty, the
               Environmental Indemnity Agreement and each other Credit Document
               to which the Guarantor is a party pursuant to an assumption
               agreement in form and substance reasonably satisfactory to the
               Administrative Agent and provides reasonable assurance to the
               Lenders of the intent of such successor entity to maintain
               continuity of the Guarantor's management following such Change
               of Control and provides such persons such certificates and legal
               opinions with respect to matters related to the Permitted
               Transaction, and the assumption of such obligations, as such
               persons shall reasonably require;

                      (4)    either of the following items (i) or (ii) is
               complied with:

                             (i)     the Permitted Transaction involves a
               company in the healthcare or hospitality business; or

                             (ii)   the Permitted Transaction involves a company
               with a minimum senior unsecured debt rating of at least "BBB"
               from S&P or Baa2 from Moody's; and

                      (5)    no Event of Default has occurred and is continuing
               or would result therefrom.

               (b)    MINIMUM CONSOLIDATED NET WORTH. The Guarantor will not

               increased by 50% of the Consolidated Net Income of the
               Guarantor for the two fiscal quarters ended on such date, if
               any (there being no reduction in the case of any such
               Consolidated Net Income which reflects a deficit);

                      (ii)   effective as of the end of the Guarantor's fiscal
               quarter ended September 30, 1999, and as of the end of each
               fiscal quarter thereafter, the foregoing amount (as it may from
               time to time be increased as herein provided), shall be increased
               by 50% of the Consolidated Net Income of the Guarantor for the
               fiscal quarter ended on such date, if any (there being no
               reduction in the case of any such Consolidated Net Income which
               reflects a deficit);

                      (iii)  the foregoing amount (as it may from time to time

               after December 31, 1998 (other than any sale or issuance to any
               Subsidiary or to management or employees pursuant to employee
               benefit plans of general application);

                      (iv)   the foregoing amount (as it may from time to time
               be increased as herein provided), shall be increased by an
               amount equal to 75% of (x) the principal amount of
               Indebtedness or (y) the higher of stated value or liquidation
               value of Redeemable Stock, as the case may be, which

               Subsidiaries; and

                      (v)    he foregoing amount (as it may from time to time be
               increased as herein provided), shall be increased by an amount
               equal to 75% of the increase in Consolidated Net Worth
               attributable to the issuance of common stock or other equity
               interests subsequent to December 31, 1998 as consideration in any

         TOTAL CAPITALIZATION. The Guarantor will not at any time permit the
         ratio of (i) its Consolidated Senior Indebtedness at such time, to (ii)
         its Consolidated Total Capitalization at such time, expressed as a
         percentage, to exceed 80.00%.

               (d)    INTEREST COVERAGE RATIO. The Guarantor will not permit the
         ratio of (i) its Consolidated EBIT for any Testing Period, to (ii) its
         Consolidated Interest Expense for such Testing Period, to be less than
         1.85 to 1.00 for any Testing Period ending on or prior to June 30,
         2000, or thereafter, less than 1.95 to 1.00 for any Testing Period
         ending on or before December 31, 2000, or thereafter, less than 2.10 to

               (f)    INTENTIONALLY OMITTED.

               (g)    TRANSACTIONS WITH AFFILIATES. The Guarantor will not, and
         will not permit any Subsidiary to, enter into any transaction or series
         of transactions with any Affiliate (other than, in the case of the
         Guarantor, any Subsidiary, and in the case of a Subsidiary, the
         Guarantor or another Subsidiary) other than in the ordinary course of
         business of and pursuant to the reasonable requirements of the
         Guarantor's or such Subsidiary's business and upon fair and reasonable
         terms no less favorable to the Guarantor or such Subsidiary than would
         obtain in a comparable arm's-length transaction with a person other
         than an Affiliate, EXCEPT agreements and transactions with and payments
         to officers, directors and shareholders and other Affiliates which are
         either (i) entered into in the ordinary course of business and not
         prohibited by any of the provisions of this Guaranty, or (ii) entered
         into outside the ordinary course of business, approved by the directors
         or shareholders of the Guarantor, and not prohibited by any of the
         provisions of this Guaranty.

         14.   CONTINUING GUARANTY; REMEDIES CUMULATIVE, ETC. This Guaranty is a
continuing guaranty, all liabilities to which it applies or may apply under the
terms hereof shall be conclusively presumed to have been created in reliance
hereon, and this Guaranty shall remain in full force and effect until terminated
as provided in section 25 hereof. No failure or delay on the part of the
Administrative Agent or any other Creditor in exercising any right, power or
privilege hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein expressly specified are cumulative and
not exclusive of any rights or remedies which the Administrative Agent or any
other Creditor would otherwise have. No notice to or demand on the Guarantor in
any case shall entitle the Guarantor to any other further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Administrative Agent or any other Creditor to any other or further action in any
circumstances without notice or demand. It is not necessary for the
Administrative Agent or any other Creditor to inquire into the capacity or
powers of the Borrower or any of its Subsidiaries or Affiliates or the officers,
directors, partners or agents acting or purporting to act on its or their
behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

         15.   ENFORCEMENT EXPENSES. The Guarantor hereby agrees to pay all
reasonable out-of-pocket costs and expenses of the Administrative Agent and each
Creditor in connection with the enforcement of this Guaranty and any amendment,
waiver or consent relating hereto (including, without limitation, the reasonable
fees and disbursements of counsel employed by the Administrative Agent or any of
the other Creditors).

         16.   SUCCESSORS AND ASSIGNS. This Guaranty shall be binding upon the
Guarantor and its successors and assigns, and shall inure to the benefit of the
Administrative Agent and the other Creditors and their successors and assigns.

         17.   AMENDMENTS AND WAIVERS. Neither this Guaranty nor any provision
hereof may be amended, waived or otherwise modified except with the written
consent of (i) the Administrative Agent, acting with the written consent of the
Required Lenders (or to the extent required by section 12.13 of the Credit
Agreement, with the written consent of each Lender); and (ii) the Guarantor;
PROVIDED, HOWEVER, that no such amendment, waiver or modification shall be made
to the definitions of the terms "Credit Document Obligations", "Designated Hedge
Document Obligations" or "Guaranteed Obligations", or to section 2, section 3,
this section 17 or section 25, without the consent of each Creditor adversely
affected thereby, and PROVIDED FURTHER that any amendment, waiver or other
modification affecting the rights and benefits of a single Class of Creditors
(and not all Creditors in a like or similar manner) shall require the written
consent of the Requisite Creditors of such Class of Creditors. For the purpose
of this Guaranty, the term "CLASS" shall mean each class of Creditors, I.E.,
whether (x) the Administrative Agent and the Lenders as holders of the Credit
Document Obligations or (y) the Designated Hedge Creditors as holders of the
Designated Hedge Document Obligations. For the purpose of this Guaranty, the
term "REQUISITE CREDITORS" of any Class shall mean (x) with respect to the
Credit Document Obligations, the Required Lenders and (y) with respect to the
Designated Hedge Document Obligations, the holders of at least 51% of all
Designated Hedge Document Obligations outstanding from time to time under the
Designated Hedge Documents.

         18.   HEADINGS DESCRIPTIVE. The headings of the several sections of
this Guaranty are inserted for convenience only and shall not in any way affect
the meaning or construction of any provision of this Guaranty.

         19.   SEVERABILITY. Any provision of this Guaranty which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         20.   RIGHT OF SETOFF. In addition to any rights now or hereafter
granted under applicable law and not by way of limitation of any such rights,
upon the occurrence and during the continuance of an Event of Default, each
Creditor is hereby authorized at any time or from time to time, without notice
to the Guarantor or to any other person, any such notice being expressly waived,
to set off and to appropriate and apply any and all deposits (general or
special) and any other indebtedness at any time held or owing by such Creditor
to or for the credit or the account of the Guarantor, against and on account of
the obligations and liabilities of the Guarantor to such Creditor under this
Guaranty, irrespective of whether or not the Administrative Agent or such
Creditor shall have made any demand hereunder and although said obligations,
liabilities, deposits or claims, or any of them, shall be contingent or
unmatured. Each Creditor agrees to promptly notify the Guarantor after any such
set off and application, PROVIDED, HOWEVER, that the failure to give such notice
shall not affect the validity of such set off and application.

         21.   NOTICES. All notices requests, demands or other communications
pursuant hereto shall be made in writing (including telegraphic, telex,

         22.   REINSTATEMENT. If claim is ever made upon the Administrative
Agent or any other Creditor for recission, repayment, recovery or restoration of
any amount or amounts received by the Administrative Agent or any other Creditor
in payment or on account of any of the Guaranteed Obligations and any of the
aforesaid payees repays all or part of said amount by reason of (x) any
judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property, or (y) any settlement or

                                       22
<PAGE>   23

such claimant (including the Borrower), THEN and in such event (i) any such
judgment, decree, order, settlement or compromise shall be binding upon the
Guarantor, notwithstanding any revocation hereof or other instrument evidencing
any liability of the Borrower, (ii) the Guarantor shall be and remain liable to
the aforesaid payees hereunder for the amount so repaid or otherwise recovered
or restored to the same extent as if such amount had never originally been
received by any such payee, and (iii) this Guaranty shall continue to be
effective or be reinstated, as the case may be, all as if such repayment or
other recovery had not occurred.

         23.   GOVERNING LAW; VENUE; WAIVER OF JURY TRIAL. (a) THIS GUARANTY AND
THE RIGHTS AND OBLIGATIONS OF THE ADMINISTRATIVE AGENT, THE CREDITORS AND OF THE
UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAW OF THE STATE OF OHIO. Any legal action or proceeding with respect to this
Guaranty may be brought in the Courts of the State of Ohio, or of the United
States of America for the Northern District of Ohio, and, by execution and
delivery of this Guaranty, the Guarantor hereby irrevocably accepts for itself
and in respect of its property, generally and unconditionally, the jurisdiction
of the aforesaid courts. The Guarantor hereby irrevocably consents to the
service of process out of any of the aforementioned courts in any such action or
proceeding by the mailing of copies thereof by registered mail, return receipt
requested, to the Guarantor at its address provided herein, such service to
become effective 30 days after such mailing, or such earlier time as may be
provided by applicable law. Nothing herein shall affect the right of the
Administrative Agent or any of the other Creditors to serve process in any other
manner permitted by law or to commence legal proceedings or otherwise proceed
against the Guarantor in any other jurisdiction.

         (b)   The Guarantor hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Guaranty or any other
Credit Document or Guaranteed Document brought in the courts referred to in
section 23(a) above and hereby further irrevocably waives and agrees not to
plead or claim in any such court that such action or proceeding brought in any
such court has been brought in an inconvenient forum.

         (c)   THE GUARANTOR, THE ADMINISTRATIVE AGENT AND EACH OTHER CREDITOR
HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY, THE
OTHER CREDIT DOCUMENTS, ANY OTHER GUARANTEED DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY.

         24.   FULL RECOURSE OBLIGATIONS; EFFECT OF FRAUDULENT TRANSFER LAWS,
ETC. It is the desire and intent of the Guarantor, the Administrative Agent and
the other Creditors that this Guaranty shall be enforced as a full recourse
obligation of the Guarantor to the fullest extent permissible under the laws and
public policies applied in each jurisdiction in which enforcement is sought. If
and to the extent that the obligations of the Guarantor under this Guaranty
would, in the absence of this sentence, be adjudicated to be invalid or
unenforceable because of any applicable state or federal law relating to
fraudulent conveyances or transfers, then the amount of the Guarantor's
liability hereunder in respect of the Guaranteed Obligations shall be deemed to
be reduced AB INITIO to that maximum amount which would be permitted without
causing the Guarantor's obligations hereunder to be so invalidated.

         25.   TERMINATION. This Guaranty will terminate when (i) the Total
Commitment has terminated and all Loans and other Guaranteed Obligations (other
than unasserted indemnity obligations) have been paid in full; or (ii) following
any request or demand by the Administrative Agent, the Guarantor shall have paid
to the Administrative Agent in full the maximum amount which the Administrative
Agent shall be entitled to recover from the Guarantor under sections 2 and 15
hereof, SUBJECT to the effect of section 5 hereof. Upon or following termination
of this Guaranty, the Administrative Agent, at the request and expense of the
Borrower and/or the Guarantor, will execute and deliver to the Guarantor a
proper instrument or instruments acknowledging the satisfaction and termination
of this Guaranty.

         26.   ENFORCEMENT ONLY BY ADMINISTRATIVE AGENT. The Creditors agree
that this Guaranty may be enforced only by the action of the Administrative
Agent, acting upon the instructions of the Required Lenders, and that no
Creditor shall have any right individually to seek to enforce or to enforce this
Guaranty, it being understood and agreed that such rights and remedies may be
exercised by the Administrative Agent, for the benefit of the Creditors, upon
the terms of this

                                       23
<PAGE>   24

Guaranty. The Administrative Agent and the other Creditors further agree that
this Guaranty may not be enforced against any director, officer or employee of
the Guarantor, as such.

         27.   GENERAL LIMITATION ON CLAIMS BY GUARANTOR. No claim may be made
by the Guarantor against the Administrative Agent or any other Creditor, or the
Affiliates, directors, officers, employees, attorneys or agents of any of them,
for any damages other than actual compensatory damages in respect of any claim
for breach of contract or any other theory of liability arising out of or
related to the transactions contemplated by this Guaranty or any of the other
Guaranteed Documents, or any act, omission or event occurring in connection
therewith; and the Guarantor hereby, to the fullest extent permitted under
applicable law, waives, releases and agrees not to sue or counterclaim upon any
such claim for any special, consequential or punitive damages, whether or not
accrued and whether or not known or suspected to exist in its favor.

         28.   ATTORNEYS, ACCOUNTANTS, ETC. OF CREDITORS HAVE NO DUTY TO
GUARANTOR. All attorneys, accountants, appraisers, consultants and other
professional persons (including the firms or other entities on behalf of which
any such person may act) retained by the Administrative Agent or any other
Creditor with respect to the transactions contemplated by the Guaranteed
Documents shall have the right to act exclusively in the interest of the
Administrative Agent or such other Creditor, as the case may be, and shall have
no duty of disclosure, duty of loyalty, duty of care, or other duty or
obligation of any type or nature whatsoever to the Guarantor, to any of its
Affiliates, or to any other person, with respect to any matters within the scope
of such representation or related to their activities in connection with such
representation. The Guarantor agrees, on behalf of itself and its Affiliates,
not to assert any claim or counterclaim against any such persons with regard to
such matters, all such claims and counterclaims, now existing or hereafter
arising, whether known or unknown, foreseen or unforeseeable, being hereby
waived, released and forever discharged.

         29.   CREDITORS NOT FIDUCIARY TO GUARANTOR, ETC. The relationship among
the Guarantor and its Affiliates, on the one hand, and the Administrative Agent
and the other Creditors, on the other hand, is solely that of debtor and
creditor, and the Administrative Agent and the other Creditors have no fiduciary
or other special relationship with the Guarantor or any of its Affiliates, and
no term or provision of any Guaranteed Document, no course of dealing, no
written or oral communication, or other action, shall be construed so as to deem
such relationship to be other than that of debtor and creditor.

         30.   COUNTERPARTS. This Guaranty may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with the Guarantor and the
Administrative Agent.

          AMENDED AND RESTATED PURCHASE RIGHTS AND FINANCING AGREEMENT

         THIS PURCHASE RIGHTS AND FINANCING AGREEMENT ("Agreement") is entered
into as of the 30th day of June, 1999, by and between ALTERRA HEALTHCARE
CORPORATION, a Delaware corporation formerly known as Alternative Living
Services, Inc. ("Alterra"), and THIRD PARTY INVESTORS I, L.L.C., a Delaware
corporation ("Purchaser").

                              W I T N E S S E T H:

         Purchaser has acquired the interest of Alterra (or its subsidiary, as
the case may be) in properties or purchase and sale agreements described in that
certain Agreement of Purchase and Sale between Alterra and Purchaser of December
31, 1998, as the same may be amended from time to time ("First Purchase
Agreement"), and in that certain Agreement of Purchase and Sale between Alterra
and Purchaser of March 31, 1999, as the same may be amended from time to time
("Second Purchase Agreement"), and may acquire the interest of Alterra (or its
subsidiary, as the case may be) in properties or purchase and sale agreements
described in that certain Option Agreement between Alterra and Purchaser of
March 31, 1999, as the same may be amended from time to time (the "Option
Agreement"). The First Purchase Agreement, the Second Purchase Agreement and the
Option Agreement are sometimes hereinafter referred to collectively as the
"Purchase Agreements." The properties which are the subject of the Purchase
Agreements (including those which are the subject of the aforesaid purchase and
sale agreements or option) are hereinafter collectively referred to as "Parcels"
and individually as a "Parcel."

         Purchaser and Alterra have agreed that Alterra shall have certain
purchase rights with respect to the Parcels.

         Purchaser and Alterra have agreed to certain other matters as more
particularly described herein, all of which agreements were originally embodied
in that certain Purchase Rights And Financing Agreement dated as of March 31,
1999 which the parties wish to amend and restate on the terms and conditions set
forth in this Agreement.

         NOW, THEREFORE, in consideration for TEN AND NO/100 DOLLARS ($10.00) in
hand paid by Alterra to Purchaser and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Alterra and Purchaser
hereby agree as follows:

         1. Purchase Rights Notice/Offer/Acceptance. Except as otherwise
provided in Section 3.c, below, and subject to any approval rights of Alterra
prior to the First Sale Date as defined in the Operating Agreement of Third
Party Investors I, L.L.C., as the same may be amended from time to time, in the
event that Purchaser desires to sell a single Parcel (the "Applicable Single
Parcel") or a group of Parcels (the "Applicable Group of Parcels"), Purchaser
shall notify Alterra thereof which notice shall include a copy of the form of
purchase and sale agreement (inclusive of all material terms other than the
purchase price) that Purchaser plans to use in connection with such sale
("Purchase Agreement Form"). Alterra shall have thirty (30)



<PAGE>   2


days in which to notify Purchaser in writing whether Alterra desires to purchase
the Applicable Single Parcel or the Applicable Group of Parcels (but only as a
Group). The aforesaid notice shall be in the form of two (2) executed (by either
Alterra or an affiliate or subsidiary thereof) originals of the Purchase
Agreement Form for the Applicable Single Parcel or Applicable Group of Parcels,
as the case may be, which purchase agreement shall have been modified to include
(a) the purchase price and (b) any other modifications that Alterra reasonably
deems appropriate. The effective date of the notice by Alterra to Purchaser of
its election to purchase the Applicable Single Parcel or Applicable Group of
Parcels is hereinafter referred to as the "Election Date." If Alterra elects not
to purchase the Applicable Single Parcel or Applicable Group of Parcels, or
otherwise does not make an election with respect to the Applicable Single Parcel
or Applicable Group of Parcels, Purchaser shall have the right at any time
thereafter to sell the Applicable Single Parcel or the Applicable Group of
Parcels (but only as a group) to a bona fide third party on substantially the
same terms (or other terms which are more favorable to Purchaser) as those set
forth in the Purchase Agreement Form and using a purchase agreement in
substantially the same form as the Purchase Agreement Form. Purchaser shall have
fifteen (15) days from the applicable Election Date for the Applicable Single
Parcel or Applicable Group of Parcels, as the case may be, to execute and return
to Alterra one (1) original of the purchase agreement executed and delivered by
Alterra therefor. If Purchaser executes and delivers an original of the purchase
agreement as aforesaid, the Applicable Single Parcel or Applicable Group of
Parcels (but only as a group) shall thereby be released from this Agreement and
Purchaser and Alterra shall proceed to close the transaction contemplated
thereby in accordance with said purchase agreement. If Purchaser does not
execute and return an original of the applicable purchase agreement to Alterra
as aforesaid, Purchaser shall be deemed to have rejected the offer of Alterra
and such offer shall terminate. For a period of six (6) months after such
rejection, the rights of Alterra hereunder shall be suspended such that
Purchaser shall have the right to enter into an agreement to sell the Applicable
Single Parcel or Applicable Group of Parcels (but only as a group) to a bona
fide third party for a purchase price in excess of the purchase price offered by
Alterra therefor and otherwise on substantially the same terms as those set
forth in the Purchase Agreement Form and using a purchase agreement in
substantially the same form as the Purchase Agreement Form. The sale
contemplated by said purchase agreement shall close within a reasonable time
after the date thereof. Upon the consummation of such sale, the Applicable
Single Parcel or each Parcel included within the Applicable Group of Parcels
shall thereby be released from this Agreement. Upon the later to occur of (a)
the expiration of the suspension period without Purchaser entering into a
permitted purchase agreement as described above or (b) the termination of a
permitted purchase agreement as described above without the consummation of the
transaction contemplated thereby, the rights of Alterra shall be reinstated such
that Purchaser shall be required to comply with the terms hereof prior to the
sale of the Applicable Single Parcel and of each Parcel included in the
Applicable Group of Parcels. To the extent that Alterra shall purchase any
Parcel pursuant to the provisions of this Section 1, Alterra shall assume any
and all obligations of Purchaser with respect to any applicable interest rate
lock, swap or similar agreement or refinancing fees payable in connection with
the Permanent Financing (as defined in Section 3.a, below) with respect to such
Parcel provided that such obligations or fees were reasonable in relation to the
Permanent Financing. The aggregate amount of such obligations and fees which
Alterra would be obligated to assume and pay shall be considered as part of the


                                       2
<PAGE>   3

purchase price offered by Alterra in determining whether the offer of any third
party is at a price in excess of the amount offered by Alterra.


         2.   General Terms of Purchase Rights.

         a.   Recorded Instrument. Within thirty (30) days after the date
hereof, Purchaser and Alterra shall execute a recordable memorandum of this
Agreement for each Parcel. Alterra shall be permitted to record a memorandum of
this Agreement in the real estate records where each Parcel is located. In
connection with any sale to a third party with respect to which Alterra no
longer has a purchase right pursuant to Section 1, Alterra shall promptly
provide evidence in writing of such fact as requested by Purchaser.

         b.   Substitution of Parcels. In the event that a Parcel is re-conveyed
to Alterra (or an affiliate thereof) and a substitution parcel conveyed to
Purchaser in accordance with the terms of this Agreement or the Purchase
Agreements, this Agreement shall be automatically released as to the Parcel
reconveyed to Alterra or its affiliate. Further, upon the conveyance of the
substitution parcel to Purchaser, this Agreement shall automatically govern said
substitution parcel and said substitution parcel shall constitute a Parcel for
the purposes of this Agreement. Contemporaneously with the conveyance of the
substitution parcel, Alterra and Purchaser shall execute a recordable memorandum
of this Agreement in accordance with Section 2(a) hereof. Alterra shall have the
right to record such memorandum as contemplated by Section 2(a) hereof.

         3.  Financing/Guaranty.

         a.  Permanent Financing; Alterra Guaranties. Purchaser and Alterra
agree that it is their mutual intent that Purchaser obtain financing from an
unrelated party or parties (collectively, the "Senior Lender"), as soon as
practicable after the date hereof, for each of the Parcels which have or may
hereafter be acquired by Purchaser pursuant to the Purchase Agreements
(including the construction and development thereof) on terms and conditions
reasonably acceptable to Purchaser ("Permanent Financing") for not less than
seventy five percent (75%) (the "Target Percentage") of Total Costs of each
Parcel. Purchaser agrees that terms substantially consistent with those set
forth in the Key Bank Financing Proposal attached hereto as Exhibit A (the "Key
Bank Financing Proposal") would be acceptable to Purchaser. Proceeds of the
Permanent Financing shall be used, in part, to discharge Purchaser's liability
to Alterra under (a) the Amended Bridge Loan Agreement between Alterra and
Purchaser of even date and (b) the other documents evidencing and securing the
loan contemplated by the Amended Bridge Loan Agreement. Purchaser agrees to use
its best efforts to obtain Permanent Financing with respect to each of the
Parcels. The parties also contemplate that Purchaser from time to time may
desire, or be required, to obtain refinancing from a Senior Lender ("Replacement
Permanent Financing") for Parcels which are subject to Permanent Financing.
Alterra, promptly upon the demand of Purchaser, shall execute unconditional
guaranties of the Purchaser's obligations (limited to eighty percent (80%) of
the "Total Costs," as hereinafter defined) pursuant to the Permanent Financing
or Replacement Permanent Financing for each Parcel in the form reasonably
required by the lender or lenders and reasonably acceptable to Alterra (each an
"Alterra Guaranty" and, collectively, the "Alterra Guaranties"). The Alterra
Guaranties shall be


                                       3
<PAGE>   4


for a period ending not later than December 31, 2010. Alterra agrees that terms
and conditions of the Alterra Guaranties may include, but not be limited to, the
financial covenants and other terms and conditions applicable to Alterra as
described in the Key Bank Financing Proposal. "Total Costs" means with respect
to each Parcel as of any given time the amount paid by Purchaser for the
acquisition of the Parcel and the aggregate "Project Costs" as of such time for
such Parcel (incurred after the date of closing of the acquisition of such
Parcel by Purchaser) as the term "Project Costs" is defined in Section 2.5 of
the Development Agreement between Purchaser and Alterra relative thereto dated
either (i) as of December 31, 1998, (ii) of even date herewith or (iii) with
respect to Parcels acquired under the Option Agreement, the closing date of such
acquisition, as the case may be, as such agreements described in clauses (i),
(ii) or (iii) may be amended from time to time.

         b.   Supplementary Financing. If after reasonable efforts by Purchaser,
Purchaser is unable to obtain Permanent Financing with Alterra Guaranties for
the Target Percentage of the Total Costs of all of the Parcels on an aggregate
basis, Alterra shall make all reasonable efforts to allocate to the Purchaser a
portion of its total financing commitments in order to permit Purchaser to be
able to obtain the Permanent Financing for the Target Percentage of Total Costs
with respect to all of the Parcels on an aggregate basis. In addition, from time
to time on or before each Closing of Pending Financing (as hereinafter defined),
Alterra shall lend to the Purchaser on the terms and conditions hereinafter set
forth (each a "Supplementary Financing") the percentage of the Total Costs with
respect to each such Parcel equal to the amount by which the percentage of Total
Costs of each such Parcel which will be a Permanently Financed Parcel (as
hereinafter defined) upon such Closing of Pending Financing is less than the
Target Percentage, provided that Alterra shall not be required to lend to
Purchaser with respect to any Parcel an amount in excess of twenty-five percent
(25%) of the Total Costs of such Parcel nor in an amount which would cause the
aggregate principal amount of all Supplementary Financings which will be
outstanding upon any Closing of Pending Financing to exceed Ten Million Dollars
($10,000,000.00). If at any time, Purchaser obtains Permanent Financing and/or
Replacement Placement Financing which causes the aggregate of all Permanent
Financing and/or Replacement Permanent Financing and Supplementary Financing to
exceed the Target Percentage of the Total Costs of all Parcels covered by such
financings, Purchaser shall pay the amount of such excess to Alterra as a
prepayment on Supplementary Financings. Each Supplementary Financing shall be at
an interest rate of eleven percent (11%) per annum, and interest shall be
payable quarterly except to the extent prohibited by any intercreditor or
subordination agreement entered into by Alterra with the Senior Lender. The
maturity date of the Supplementary Financing with respect to any Parcel shall be
the same as the scheduled maturity date of the Permanent Financing or
Replacement Permanent Financing with respect to such Parcel. The Supplementary
Financing with respect to any Parcel shall be evidenced by a promissory note of
Purchaser in form reasonably acceptable to Purchaser, Alterra and the Senior
Lender and, if permitted by the Senior Lender, will be secured by a mortgage and
other security interests (including a security interest in all the outstanding
limited liability company member interests in Purchaser other than that held by
Alterra), subordinate to the mortgage and other security instruments securing
the Permanent Financing or Replacement Permanent Financing, and otherwise on
terms and conditions reasonably acceptable to Purchaser, Alterra and the Senior
Lender. The Senior Lender must enter into an intercreditor agreement with
Alterra which provides, without limitation, that Alterra shall


                                       4
<PAGE>   5



have the right, but not the obligation, to acquire the interest of the Senior
Lender or cure the default of Purchaser (in either case, within 10 days after
written notice from the Senior Lender) prior to any foreclosure, deed in lieu of
foreclosure or similar action with respect to the collateral securing the
Permanent Financing or Replacement Permanent Financing. Subject to the
foregoing, the terms of said intercreditor agreement shall be reasonably
acceptable to Purchaser and Alterra. "Closing of Pending Financing" means the
closing of Permanent Financing or Replacement Permanent Financing. "Permanently
Financed Parcels" means all Parcels with respect to which Permanent Financing or
Replacement Permanent Financing is in effect, except any Parcels which are
Financing In Process Parcels. "Financing In Process Parcels" means all Parcels
which are in process of being financed with Permanent Financing or refinanced
with Replacement Permanent Financing.

         c. Financing Default by Alterra. In the event that after the closing of
Permanent Financing or Replacement Permanent Financing, Alterra or Purchaser are
notified by the Senior Lender that Alterra has defaulted on any covenant
applicable to Alterra in the Alterra Guaranties and as a result thereof the
obligation of Alterra with respect to the Alterra Guaranties or of Purchaser
with respect to the Permanent Financing or Replacement Permanent Financing for
any one or more Parcels is due and payable, then unless and until such default
and the effect thereof have been cured to the satisfaction of or otherwise
waived by the Senior Lender, (a) subject to Section 1 hereof as modified by this
subsection, Purchaser may, at its option, enter into an agreement of sale with
respect to any or all of such Parcels to a third party on such terms and
conditions as determined by Purchaser provided, however, as to the Alterra
purchase right in Section 1 hereof, the thirty (30) day period in which Alterra
has the right to notify Purchaser whether it desires to purchase a Parcel shall
be reduced to ten (10) days and within two business days after Purchaser
notifies Alterra of the acceptance of Alterra's offer, Alterra shall be required
to deposit an amount equal to 10% of the amount of its offer in escrow with a
bank or other party reasonably acceptable to Purchaser to secure Alterra's
obligations under the purchase agreement under reasonable terms for a deposit
intended to secure the obligation of a purchaser to complete a real estate
purchase and if Alterra defaults in its obligation to make such deposit, all of
Alterra's rights under Section 1 with respect to such Parcels shall be
extinguished and (b) in connection with the sale of any Parcel pursuant to the
provisions of clause (a) of this sentence, Purchaser may, at its option,
terminate the Assisted Living Consultant and Management Services Agreement and
Development Agreement between Alterra and Purchaser with respect to any such
Parcel effective with the date of sale thereof, provided that Purchaser shall
first repay, to the extent incurred in connection with such Parcel, all amounts
of principal and interest outstanding pursuant to (i) any Supplementary
Financing, (ii) those two (2) certain Management Fee Loan Notes dated December
31, 1998 and March 31, 1999, respectively, and (iii) those two (2) certain
Working Capital Loan Notes also dated as of December 31, 1998 and March 31,
1999, respectively. Alterra, in its capacity as a member of Third Party
Investors I, L.L.C. hereby consents to the sale of any Parcel pursuant to the
provisions of this Section 3.c which may occur prior to the First Sale Date as
defined in the Operating Agreement of Third Party Investors I, L.L.C., as
amended from time to time.

         4.       Miscellaneous

<PAGE>   6


         a.   Agreement Binding. This Agreement shall be binding upon each party
hereto and such party's successors and assigns and shall inure to the benefit of
each party hereto and such party's successors and assigns. Alterra may assign

the prior written consent of Purchaser.

         b.   Entire Agreement. This Agreement contains the entire agreement of
the parties hereto with respect to the matters contained herein, and no prior
agreement or understanding pertaining to any of the matters connected with this
transaction shall be effective for any purpose. Except as may be otherwise
provided herein, the agreements embodied herein may not be amended except by an
agreement in writing signed by the parties hereto.

         c.   Facsimile Execution. In the event of delivery by facsimile, such
delivery shall be binding as if an original had been delivered and the
delivering party covenants and agrees that originals will be sent that same day
by overnight delivery.

         d.   Time is of the Essence. Time is of the essence of the transaction
contemplated by this Agreement.

         e.   Governing Law. With respect to matters pertaining to the
individual Parcels, this Agreement shall be governed by and construed in
accordance with the laws of the state in which such Parcel is located. Except as
set forth in the immediately preceding sentence, this Agreement shall be
governed by the laws of the state of Wisconsin.

         f.   Interpretation; Date of Agreement. The titles, captions and
paragraph headings are inserted for convenience only and are in no way intended
to interpret, define, limit or expand the scope or content of this Agreement or
any provision hereof. If any time period under this Agreement ends on a day

right to waive, in whole or in part, any provision hereof which is for the
benefit of the party so waiving.

         h.   Counterparts. This Agreement may be executed in separate
counterparts, each of which shall be deemed an original and all of which, taken
as a whole, shall be deemed to be one (1) original. This Agreement shall be

least one (1) counterpart even though no one (1) counterpart contains the
signatures of all of the parties to this Agreement.

         i.   Non-Waiver. Unless otherwise expressly provided herein, no waiver
by Alterra or Purchaser of any provision hereof shall be deemed to have been
made unless expressed in writing and signed by such party. No delay or omission
in the exercise of any right or remedy accruing to Alterra or Purchaser upon any
breach under this Agreement shall impair such right or remedy


                                       6
<PAGE>   7


or be construed as a waiver of any such breach theretofore or thereafter
occurring. The waiver by Alterra or Purchaser of any breach of any term,
covenant or condition herein stated shall not be deemed to be a waiver of any
other breach, or of a subsequent breach of the same or any other term, covenant
or condition herein contained. Each party hereby reserves the right to waive any
provision hereof made or intended for the benefit of the waiving party.

         j.   Rights Cumulative. All rights, powers, options or remedies
afforded to Alterra or Purchaser either hereunder or by law shall be cumulative
and not alternative, and the exercise of one right, power, option or remedy
shall not bar other rights, powers, options or remedies allowed herein or by
law, unless expressly provided to the contrary herein.

days after mailing. Refusal of delivery shall be deemed effective delivery on

                 COMMITMENT TO LEND, BORROWING PROCEDURES, ETC.

Section 2.1  Loans

         (a) Amount. Lender agrees, from the Closing Date until the Maturity
Date described in Section 2.1(d) below and upon the terms and conditions herein
set forth, to make a loan or loans to Borrower in the aggregate principal amount
of up to the maximum amount for which Lender may be obligated under the Guaranty
(the "Commitment") (each such loan in herein referred to as the "Loan," all such
loans are herein referred to as "Loans," and the aggregate amount of all such
Loans outstanding from time to time, the "Loan Amount"). Borrower shall repay
each of the outstanding Loans on its Maturity Date, or such earlier date if
payment of the Loans are accelerated in accordance herewith.

         (b) Borrowings. If i) the Lender makes any required payments under the
Guaranty, or ii) the Lender makes any advances for the benefit of the Borrower
which are reasonably required to avoid or cure a default or event of default
under the Key Loan, or iii) any amount shall be due and owing under any of the
Other Loan Agreements and the Intercreditor Agreement prohibits the payment by
Borrower of such amount due (unless such prohibition is the result of the
Lender's default under the Guaranty or the Lender's breach of any Management
Agreement or Development Agreement), then the amount of any such payment under
i) or advance under ii) or the amount due under iii) shall be deemed to have
borrowed from the Lender and the Lender shall be deemed to have made a Loan to
the Borrower in such amount with such Loan being made on the date upon which the
Lender makes any such


                                       4
<PAGE>   5


payment or advance or such amount is due. The Loans hereunder shall not exceed
the Commitment.

         (c) Convertible Subordinated Loan Note. The obligations of Borrower to
repay the Loans shall be evidenced by one or more promissory notes of the
Borrower in the form attached hereto as Exhibit A, executed by Borrower and
delivered to Lender as of the date of each Loan hereunder and in the principal
amount of each such Loan.

         (d) Payments. Unless payment of the Loans are accelerated upon
occurrence of an Event of Default pursuant to Section 8.2 hereof, the aggregate
outstanding principal amount of the Loans relating to a Project, together with
all accrued unpaid interest thereon, shall be due and payable (the "Maturity
Date") on the earlier of i) the date on which the Mini-Perm Period was
originally scheduled (or would have been so scheduled had the Mini-Perm Period
election been made after the maximum possible construction period under Section
2.7 of the Key Credit Agreement) to expire for such Project, and ii) with
respect of borrowings under Section 2.1(b)(iii), thirty (30) days after the date
of demand by Lender for payments that are no longer prohibited by the
Intercreditor Agreement. However, while the Intercreditor Agreement is in
effect, no payment of principal and interest on any of the Loans, including any
mandatory prepayments under Section 2.3, shall be due and payable to the extent
and for the period that the Intercreditor Agreement prohibits such payment.

         (e) Interest Rate. The Loans shall bear interest, compounded quarterly,
during the period from and including the date of funding to (but not including)
the date the Loans are paid in full, at the per annum rates set forth in the
Note. However, any Conversion Amount which Lender converts into Class C Member
Interests under Article III shall bear no interest (including any interest which
has been compounded) retroactive to the date such amount was first advanced
under this Agreement.

Section 2.2  Optional Prepayment.

         The principal amount of each Loan may be repaid or prepaid in full or
in part at any time prior to the Maturity Date, without premium or penalty,
provided that, for Loans as to which the elapsed time from the date the amount
was advanced under this Agreement exceeds six months (and are therefore subject
to conversion under Section 3.1), the Borrower gives the Lender not less than
thirty (30) days prior notice (the "Prepayment Notice Period") of the proposed
prepayment date.

Section 2.3  Mandatory Prepayment.

         Borrower shall pay to Lender for application to the Loans in accordance
with Section 2.4(c) an amount equal to all distributions made by Borrower to, on
account of, or for the benefit of its members, except for i) Tax Distributions,
and ii) distributions allowed under Section 9.2(d) of the Key Credit Agreement
and the "further except" provisions of Section 9.2 of the Key Credit Agreement.
However, no distribution may be made pursuant to ii) above unless Borrower on or
before the date of the distribution has paid or caused to be paid in full


                                       5
<PAGE>   6



all loans (including accrued interest) related to the Project involved in the
distribution which loans are then owed to Lender under this Agreement and any of
the Other Loan Agreements.

Section 2.4  Manner of Payment.

         (a) Each payment (including prepayments) by Borrower on account of the
principal or interest on the Loan shall be made on the dates specified for
payment under this Agreement (or, in the case of prepayments, on the dates
specified by Borrower) to the Lender in lawful money of the United States of
America in immediately available funds.

         (b) If any payment under this Agreement shall be specified to be made
upon a day which is not a Business Day, it shall be made on the next succeeding
day which is a Business Day, and such extension of time shall in such case be
included in computing interest, if any, in connection with such payment.

         (c) If some or less than all amounts due from Borrower are received by
Lender, Lender shall distribute such amounts in the following order of priority:
(i) to the payment of all amounts then due and payable under this Agreement
other than interest or principal; (ii) to the payment of interest then due and
payable on the Loan; and (iii) to the repayment or prepayment of the principal
balance of the Loans, with such repayment or prepayment being applied first to
the Loans most recently made (except any prepayments made under Section 2.2
shall be applied to the Loans specified by Borrower).

Section 2.5  Basis of Calculation of Interest.

         All interest payable hereunder shall be calculated on the basis of the
360/365 method, which computes a daily amount of interest for a hypothetical
year of 360 days, then multiplies such amount by the actual number of days
elapsed in an interest calculation period.

Section 2.6  Maximum Interest Rate.

         In no event shall the amount of interest due or payable under the Note
exceed the maximum rate of interest allowed by applicable law, and in the event
that any such payment is inadvertently paid by Borrower or inadvertently
received by Lender, then such excess sum shall be credited as a payment of
principal, unless Borrower shall notify Lender, in writing, that Borrower elects
to have such excess sum returned to it forthwith. It is the express intent
hereof that Borrower not pay, and that Lender not receive, directly or
indirectly, in any manner whatsoever, interest in excess of that which would
lawfully be paid by Borrower under applicable law.

                                   ARTICLE III
                               OPTIONAL CONVERSION

         Section 3.1 Right of Optional Conversion. Subject to and upon
compliance with the provisions hereof, the Lender shall have the right, at its
option, at any time and from time to


                                       6

time, to convert prior to the close of business on the Maturity Date the
Conversion Amount (or a portion thereof) into Class C Member Interests in the
Borrower based on and subject to the amount of time elapsed from the date the
amount was advanced under this Agreement pursuant to the following schedule:

- ------------------------------------------------------------ ---------------------------------------------------------
</TABLE>


         Notwithstanding the foregoing, the Lender's rights to convert the
Conversion Amount shall terminate upon the expiration of the Prepayment Notice
Period to the extent of the Prepayment Amount to which such Prepayment Notice
Period relates, unless the Borrower shall default in the payment of such
Prepayment Amount.

         Section 3.2 Process for Optional Conversion. In order to exercise the
conversion privilege with respect to any of the Conversion Amount, the Lender
shall give to the Borrower a Conversion Notice specifying the amount of the
Conversion Amount to be converted.

         Section 3.3 Issuance and Amount of Member Interest. As promptly as
practicable after satisfaction of the requirements for conversion set forth
above, the Borrower shall cause to be delivered to the Lender at its offices an
amendment to the Operating Agreement reflecting the Lender's membership interest
therein resulting from the Conversion Amount so converted. The Conversion Amount
shall be convertible into additional Class C Member Interests in the Borrower
based on the portion of the Conversion Amount converted being an Additional
Capital Contribution by Lender under the Operating Agreement (with no obligation
or right of the Borrower's Class B Member to make a proportionate Additional
Capital Contribution to prevent dilution of its Membership Interest as defined
in the Operating Agreement).

         Each conversion shall be deemed to have been effected on the date on
which the requirements set forth above in this Section 3 have been satisfied.

          FOR VALUE RECEIVED, the undersigned, THIRD PARTY INVESTORS I, LLC, a
Delaware limited liability company ("Borrower"), promises to pay to the order of
Alterra Healthcare Corporation, a Delaware corporation ("Lender") and, together
with any holder hereof ("Holder"), at 450 N. Sunnyslope Rd., Suite 300,
Brookfield, Wisconsin 53005 (or at such other place as the Holder may designate
in writing to Borrower), the principal amount of ______________________________
AND NO/100 DOLLARS ($____________), or, if less, the unpaid aggregate principal
amount of all loans made from time to time hereunder, plus interest as
hereinafter provided.

          All capitalized terms used herein shall have the meanings ascribed to
such terms in that certain Convertible Subordinated Loan Agreement dated as of
September 30, 1999 by and between Borrower and Lender (the "Loan Agreement"),
except to the extent that such capitalized terms are otherwise defined or
limited herein.

          The aggregate Loan Amount of all outstanding Loans relating to a
Project made pursuant to the Loan Agreement, together with accrued and unpaid
interest thereon, shall be paid as provided in Section 2 of the Loan Agreement.

          Borrower may repay all or any portion of the principal amount of this
Note in full or in part at any time prior to the Maturity Date, without premium
or penalty, in the manner set forth in the Loan Agreement.

          The principal amount of outstanding Loans shall bear interest during
the period from and including the date of funding of such Loans to (but not
including) the date the principal amount thereof is paid in full, at a rate per
annum equal to the lesser of i) the "Prime Rate" as published from time to time
in the Money Rates Section of The Wall Street Journal or its successor plus one
percent (1%) (the "Applicable Rate"), and ii) eleven percent (11%). However, no
interest shall be payable on any principal of the Loans which are converted
under Article III of the Loan Agreement.

          Interest shall be calculated on the basis of the 360/365 method, which
computes a daily amount of interest for a hypothetical year of 360 days, then
multiplies such amount by the actual number of days elapsed in an interest
calculation period. All past due amounts of principal of, and to the extent
permitted by applicable law, unpaid interest on, this Note from time to time
outstanding, shall bear interest at a rate equal to the Applicable Rate plus two
percent (2%).

          In no event shall the amount of interest due or payable hereunder
exceed the maximum rate of interest allowed by applicable law, and in the event
any such payment is inadvertently paid by the undersigned or inadvertently
received by Holder, then such excess sum shall be credited as a payment of
principal, unless the undersigned shall notify Holder, in writing that the
undersigned elects to have such excess sum returned to it forthwith. It is the
express intent hereof that the undersigned not pay and that Holder not receive,
directly or indirectly, in any manner whatsoever, interest in excess of that
which may be lawfully paid by the undersigned under applicable law.

          This Note is entitled to the benefits of the Loan Agreement which
contains provisions with respect to the conversion of the principal amount of
the Loans, the acceleration of the maturity of this Note upon the happening of
certain stated events, and provisions for prepayment.

          Should an Event of Default occur under the Loan Agreement, then, at
any time during which such Event of Default shall continue, Holder shall have
the right and option, in its sole discretion, to exercise any and all of the
remedies provided and available to it under the Loan Agreement.

the Borrower, any guarantor, endorser or any other Person, hereby expressly
waive presentation, demand of payment, protest, notice for demand of payment,
protest and notice of non-payment, or any other notice of any kind with respect
thereto.

          No delay or failure on the part of Holder in the exercise of any right
or remedy hereunder, under the Loan Agreement or under the Equity Pledge
Agreement, or at law or in equity, shall operate as a waiver thereof, and no
single or partial exercise by the Holder of any right or remedy hereunder, under
the Loan Agreement, the Equity Pledge Agreement, or at law or in equity, shall
preclude or estop another or further exercise thereof or the exercise of any
other right or remedy.

          Principal and interest on this Note shall be payable and paid in
lawful money of the United States of America.

remedies given by this Note or the Loan Agreement or the Equity Pledge Agreement
and no party to this instrument shall be discharged from the obligations or
undertakings hereunder (a) should the Holder release or agree not to sue any

recourse, or (b) should the Holder agree to suspend the right to enforce this
Note or the Holder's interest in any collateral pledged or any guaranty given to
secure this Note against such Person or other discharge such Person.

interpreted, and all rights and obligations of the parties hereunder determined,

Section 2.1  Loans

     (a) Amount. Lender agrees, from the Closing Date until the Maturity Date
described in Section 2.1(d) below and upon the terms and conditions herein set
forth, to make a loan or loans to Borrower in the aggregate principal amount of
up to Ten Million Dollars ($10,000,000) (the "Commitment") (each such loan in
herein referred to as the "Loan," all such loans are herein referred to as
"Loans," and the aggregate amount of all such Loans outstanding from time to
time, the "Loan Amount").

     (b) Borrowings. Borrower authorizes and directs Lender, and Lender agrees,
to make Loans by funding on their due dates construction draws for the Projects
which have been

                                      -3-
<PAGE>   4



approved by Lender under the Development Agreements and Lender shall give
Borrower notice of such Loans on a monthly basis which notice shall include the
amount, the Project and the draw involved. In the event that Borrower shall
withdraw such authorization and direction, which it may do in its absolute
discretion by written notice to Lender, Borrower shall elect to borrow pursuant
hereto by giving written notice to the Lender not later than three (3) Business
Days prior to the proposed date of such borrowing. Each such notice of borrowing
shall be by telecopy, promptly confirmed by letter, and shall specify therein:
(i) the date of such proposed borrowing, which shall be a Business Day; (ii) the
amount of such proposed borrowing which, when aggregated together with all other
outstanding Loans, shall not exceed the Commitment; and (iii) the bank account
or accounts to which the proceeds of such Loan should be paid by Lender.

     (c) Bridge Construction Loan Note. The obligations of Borrower to repay the
Loans shall be evidenced by Borrower's promissory note in the form attached
hereto as Exhibit A, dated the Closing Date and payable to the order of Lender
for the principal sum of $10,000,000, or such Loan Amount as shall be
outstanding hereunder from time to time, with interest as therein provided.

     (d) Payments. Unless payment of the Loans are accelerated upon occurrence
of an Event of Default pursuant to Section 7.2 hereof, the aggregate outstanding
principal amount of the Loans as to each Project, together with all accrued
interest thereon, shall be due and payable from time to time in the amounts of
and on the dates of receipt by Borrower of proceeds of Key Loans relating to
such Project, with any unpaid principal and accrued interest due and payable in
full on or before the 120th day following issuance of the certificate of
occupancy for the last Project to be completed (the "Maturity Date"). Borrower
authorizes and directs Lender, and Lender agrees, to immediately apply such
proceeds from the Key Loans over which Lender has authority as Borrower's agent
or otherwise to the repayment of the Loans and Lender shall promptly give
Borrower notice of each such repayment which notice shall include the amount,
the Project and the draw involved. Notwithstanding anything in this Agreement to
the contrary, no amount shall be due and payable on the Loans or under this
Agreement or any of the Loan Documents to the extent and during such time or
times as such payment by Borrower is prohibited by the Intercreditor Agreement.
However, if the prohibition is not due to the default of the Lender under the
Guaranty or to the breach of the Lender under any Management Agreement or
Development Agreement, then such amounts due and payable but prohibited by such
Intercreditor Agreement shall be deemed paid on the date due with proceeds of,
and shall be deemed advances under the Convertible Subordinated Loan Agreement
dated the date of this Agreement between the Lender and the Borrower.

     (e) Interest Rate. The Loans shall bear interest, compounded quarterly from
and after the date of this Agreement, during the period from and including the
date of funding to (but not including) the date the Loans are paid in full, at
the per annum rate set forth in the Note.

Section 2.2  Prepayment.

     The principal amount of the Loans may be repaid or prepaid in full or in
part at any time prior to the date payments of principal are due, without
premium or penalty.

Section 2.3  Manner of Payment.

     (a) Each payment (including prepayments) by Borrower on account of the
principal or interest on the Loans shall be made on the dates specified for
payment under this Agreement (or, as to prepayments, any date specified by the
Borrower) to the Lender in lawful money of the United States of America in
immediately available funds.

     (b) If any payment under this Agreement shall be specified to be made upon
a day which is not a Business Day, it shall be made on the next succeeding day
which is a Business Day, and such extension of time shall in such case be
included in computing interest, if any, in connection with such payment.

     (c) Amounts received by Lender with respect to Loans shall be applied in
the following order of priority: (i) to the payment of all amounts then due and
payable under this Agreement other than interest or principal; (ii) to the
payment of interest then due and payable on the Loan; and (iii) to the repayment
or prepayment of the principal balance of the Loans.

Section 2.4  Basis of Calculation of Interest.

     All interest payable hereunder shall be calculated on the basis of the
360/365 method, which computes a daily amount of interest for a hypothetical
year of 360 days, then multiplies such amount by the actual number of days
elapsed in an interest calculation period.

Section 2.5  Maximum Interest Rate.

     In no event shall the amount of interest due or payable under the Note
exceed the maximum rate of interest allowed by applicable law, and in the event
that any such payment is inadvertently paid by Borrower or inadvertently
received by Lender, then such excess sum shall be credited as a payment of
principal, unless Borrower shall notify Lender, in writing, that Borrower elects
to have such excess sum returned to it forthwith. It is the express intent
hereof that Borrower not pay, and that Lender not receive, directly or
indirectly, in any manner whatsoever, interest in excess of that which would
lawfully be paid by Borrower under applicable law.

other power or right. Remedies provided for herein are cumulative and not
exclusive of any remedies which may be available to the Lender at law or in
equity. No notice to or demand on the Borrower required hereunder or under the
Note shall in any event entitle Borrower to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the right of
Lender to any other or further action and any circumstances without notice or
demand. No amendment, modification or waiver of, or consent with respect to, any
provision of this Agreement or the Note shall in any event be effective unless
the same shall be in writing and signed and delivered by the party affected by
such amendment or modification or making the waiver. Any waiver of any provision
of this Agreement or the Note, and any consent to any departure by Borrower from
the terms of any provision of this Agreement or the Note, shall be effective
only in the specific instance and for the specific purpose for which given.

the Loan Agreement, the Equity Pledge Agreement, or at law or in equity, shall
preclude or estop another or further exercise thereof or the exercise of any
other right or remedy.

Borrower) to the Lender in lawful money of the United States of America in
immediately available funds.

         (b)  If any payment under this Agreement shall be specified to be made

         In no event shall the amount of interest due or payable under the Note
exceed the maximum rate of interest allowed by applicable law, and in the event
that any such payment is inadvertently paid by Borrower or inadvertently
received by Lender, then such excess sum shall be credited as a payment of

to have such excess sum returned to it forthwith. It is the express intent
hereof that Borrower not pay, and that Lender not receive, directly or
indirectly, in any manner whatsoever, interest in excess of that which would

proceeding under any bankruptcy or insolvency law, or any dissolution or

subject to any applicable period of grace.

Section 7.2   Remedies.

         If an Event of Default shall have occurred and shall be continuing,
Lender shall have the right at its option, and in its sole discretion, to
declare all amounts outstanding under the Note and this Agreement to be
immediately due and payable (except that if an event described in Section 7.1(b)
occurs, all amounts outstanding under the Note and this Agreement shall
automatically become immediately due and payable). Lender shall promptly advise
Borrower, in writing, of any such declaration, but failure to do so shall not
impair the effect of such declaration. Lender shall also be entitled to exercise
any and all remedies available to it, at law or equity.


                                  ARTICLE VIII
                                  MISCELLANEOUS

Section 8.1   Waiver and Amendments.

         No failure or delay on the part of Lender in the exercise of any power
or right, and no course of dealing between Borrower and Lender, shall operate as
a waiver of such power or right, nor shall any single or partial exercise of any
power or right preclude other or further exercise thereof or the exercise of any
other power or right. Remedies provided for herein are cumulative and not
exclusive of any remedies which may be available to the Lender at law or in
equity. No notice to or demand on the Borrower required hereunder or under the
Note shall in any event entitle Borrower to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the right of
Lender to any other or further action and any circumstances without notice or
demand. No amendment, modification or waiver of, or consent with respect to, any
provision of this Agreement or the Note shall in any event be effective unless
the same shall be in writing and signed and delivered by the party affected by
such amendment or modification or making the waiver. Any waiver of any provision
of this Agreement or the Note, and any consent to any departure by Borrower from
the terms of any provision of this Agreement or the Note, shall be effective
only in the specific instance and for the specific purpose for which given.

                        SUPPLEMENTARY FINANCING LOAN NOTE

$10,000,000                                                   September 30, 1999


         FOR VALUE RECEIVED, the undersigned, THIRD PARTY INVESTORS I, LLC, a
Delaware limited liability company ("Borrower"), promises to pay to the order of
Alterra Healthcare Corporation, a Delaware corporation ("Lender") and, together
with any holder hereof ("Holder"), at 450 N. Sunnyslope Rd., Suite 300,
Brookfield, Wisconsin 53005 (or at such other place as the Holder may designate
in writing to Borrower), the principal amount of TEN MILLION AND NO/100 DOLLARS
($10,000,000),or, if less, the unpaid aggregate principal amount of all loans
made from time to time hereunder, plus interest as hereinafter provided.

         All capitalized terms used herein shall have the meanings ascribed to
such terms in that certain Supplementary Financing Loan Agreement dated as of
September 30, 1999 by and between Borrower and Lender (the "Loan Agreement"),
except to the extent that such capitalized terms are otherwise defined or
limited herein.

         The aggregate Loan Amount of the Loans relating to each Project made
pursuant to the Loan Agreement, together with accrued and unpaid interest
thereon, shall be paid in full on the maturity date of the Key Loan for such
Project.

         Borrower may repay all or any portion of the principal amount of this
Note in full or in part at any time prior to the date payments of principal are
due, without premium or penalty, in the manner set forth in the Loan Agreement.

         The principal amount of outstanding Loans shall bear interest during
the period from and including the date of funding of such Loans to (but not
including) the date the principal amount thereof is paid in full, at the rate of
11% per annum rate. Accrued interest on Loans shall be payable as provided in
the Loan Agreement.

         Interest shall be calculated on the basis of the 360/365 method, which
computes a daily amount of interest for a hypothetical year of 360 days, then
multiplies such amount by the actual number of days elapsed in an interest
calculation period. All past due amounts of principal of, and to the extent
permitted by applicable law, unpaid interest on, this Note from time to time
outstanding, shall bear interest at a rate equal to the then Applicable Rate
plus two percent (2%).

         In no event shall the amount of interest due or payable hereunder
exceed the maximum rate of interest allowed by applicable law, and in the event
any such payment is inadvertently paid by the undersigned or inadvertently
received by Holder, then such excess sum shall be

<PAGE>   2
credited as a payment of principal, unless the undersigned shall notify Holder,
in writing that the undersigned elects to have such excess sum returned to it
forthwith. It is the express intent hereof that the undersigned not pay and that
Holder not receive, directly or indirectly, in any manner whatsoever, interest
in excess of that which may be lawfully paid by the undersigned under applicable
law.

         This Note is entitled to the benefits of the Loan Agreement, which
contains provisions with respect to the acceleration of the maturity of this
Note upon the happening of certain stated events, and provisions for prepayment.

         Should an Event of Default occur under the Loan Agreement, then, at any
time thereafter, Holder shall have the right and option, in its sole discretion,
to exercise any and all of the remedies provided and available to it under the
Loan Agreement.

         All parties now or hereafter liable with respect to this Note, whether
the Borrower, any guarantor, endorser or any other Person, hereby expressly
waive presentation, demand of payment, protest, notice for demand of payment,
protest and notice of non-payment, or any other notice of any kind with respect
thereto.

         No delay or failure on the part of Holder in the exercise of any right
or remedy hereunder, under the Loan Agreement or under the Equity Pledge
Agreement, or at law or in equity, shall operate as a waiver thereof, and no
single or partial exercise by the Holder of any right or remedy hereunder, under
the Loan Agreement, the Equity Pledge Agreement, or at law or in equity, shall
preclude or estop another or further exercise thereof or the exercise of any
other right or remedy.

         Principal and interest on this Note shall be payable and paid in lawful
money of the United States of America.

         Time is of the essence of this Note, and, in case this Note is
collected by law or through an attorney at law or under advice therefrom,
Borrower agrees to pay all costs of collection, including reasonable attorneys'
fees.

         Holder shall be under no duty to exercise any or all of the rights and
remedies given by this Note or the Loan Agreement or either of the Equity Pledge
Agreements and no party to this instrument shall be discharged from the
obligations or undertakings hereunder (a) should the Holder release or agree not
to sue any Person against whom the party has, to the knowledge of the Holder, a
right to recourse, or (b) should the Holder agree to suspend the right to
enforce this Note or the Holder's interest in any collateral pledged or any
guaranty given to secure this Note against such Person or other discharge such
Person.

         The provisions of this Note shall be construed and interpreted, and all
rights and obligations of the parties hereunder determined, in accordance with
the laws of the State of Wisconsin.

         Maintain Liquidity, at all times during the term of the Credit
Facility, measured quarterly, of not less than the greater of (a) $15,000,000 or
(b) the Guarantor's Debt Service for the ninety (90) day period beginning on the
date of determination. For purposes of this Section 3.2.3A, the term `Liquidity'
shall mean, at any time, the sum of (i) all cash of the Guarantor at such time
plus (ii) seventy-five percent (75%) of the aggregate costs (as determined in
accordance with GAAP) expended by Guarantor with respect to all Facilities owned
by the Guarantor at such time that are not subject to a Lien (including any such
Facilities that are under construction). The term `Guarantor's Debt Service'
means, with respect to any period, the sum of all lease payments and

<PAGE>   3

interest and principal payments payable during such period on the aggregate
indebtedness of the Guarantor for Facilities that, at the time of determination,
do not constitute Guarantor's Stabilized Projects. The term `Guarantor's
Stabilized Project' means any Facility owned by Guarantor that (i) has a
Resident Occupancy of at least 95% and (ii) has achieved a ratio of Net
Operating Income to Debt Service of not less than 1.25 to 1.00 measured for
three consecutive months. The computation of the financial test set forth in
this Section shall be based on the Guarantor's quarterly financial statements
delivered to Lenders and the information used in the preparation thereof."

                                  ARTICLE III.

                           Conditions of Effectiveness

         Section 3.1. Effective Date. This Amendment shall become effective as
of July 1, 1999, when, and only when, Agent shall have received, at Agent's
office, a counterpart of this Amendment executed and delivered by Guarantor and
each Lender.

                                   ARTICLE IV.

                         Representations and Warranties

         Section 4.1. Representations and Warranties of Guarantor. In order to
induce each Lender to enter into this Amendment, Guarantor represents and

Original Guaranty are true and correct at and as of the time of the
effectiveness hereof.

         (b) Guarantor is duly authorized to execute and deliver this Amendment
and is and will continue to be duly authorized to perform its obligations under
the Guaranty. Guarantor has duly taken all corporate action necessary to
authorize the execution and delivery of this Amendment and to authorize the
performance of the obligations of Guarantor hereunder.

         (c) The execution and delivery by Guarantor of this Amendment, the
performance by Guarantor of its obligations hereunder and the consummation of
the transactions contemplated hereby do not and will not conflict with any
provision of law, statute, rule or regulation or of the articles of
incorporation and bylaws of Guarantor, or of any material agreement, judgment,
license, order or permit applicable to or binding upon Guarantor, or result in
the creation of any lien, charge or encumbrance upon any assets or properties of
Guarantor. Except for those which have been obtained, no consent, approval,
authorization or order of any court or governmental authority or third party is
required in connection with the execution and delivery by Guarantor of this
Amendment or to consummate the transactions contemplated hereby.

Guaranty


<PAGE>   4


will be a legal and binding obligation of Guarantor, enforceable in accordance
with its terms, except as limited by bankruptcy, insolvency or similar laws of
general application relating to the enforcement of creditors' rights and by
equitable principles of general application.

         (e) The audited annual consolidated financial statements of Guarantor
dated as of December 31, 1998 and the unaudited quarterly consolidated financial
statements of Guarantor dated as of June 30, 1999 fairly present the
consolidated financial position at such dates and the consolidated statement of
operations and the changes in consolidated financial position for the periods
ending on such dates for Guarantor. Copies of such financial statements have
heretofore been delivered to each Lender. Since such dates no material adverse
change has occurred in the financial condition or businesses or in the
consolidated financial condition or businesses of Guarantor.
