                        MASTER CREDIT FACILITY AGREEMENT

         THIS MASTER CREDIT FACILITY AGREEMENT is made as of the 29th day of
May, 2002 by and among (a) (i) SUN SECURED FINANCING LLC, a Michigan limited
liability company ("SSF"), (ii) ASPEN-FT. COLLINS LIMITED PARTNERSHIP, a
Michigan limited partnership ("Aspen"), and (iii) SUN SECURED FINANCING HOUSTON
LIMITED PARTNERSHIP, a Michigan limited partnership ("Houston") (individually
and collectively, SSF, Aspen and Houston, "Borrower"), and (b) ARCS COMMERCIAL
MORTGAGE CO., L.P., a California limited partnership ("Lender").

                                    RECITALS

         A. Borrower owns one or more Manufactured Housing Communities (unless
otherwise defined or the context clearly indicates otherwise, capitalized terms
shall have the meanings ascribed to such terms in Appendix I of this Agreement)
as more particularly described in Exhibit A to this Agreement.

         B. Borrower has requested that Lender establish a $101,760,000 Credit
Facility in favor of Borrower, comprised initially of a $101,760,000 Variable
Facility, all or part of which can be converted to a Fixed Facility in
accordance with, and subject to, the terms and conditions of this Agreement.

         C. To secure the obligations of Borrower under this Agreement and the
other Loan Documents issued in connection with the Credit Facility, Borrower
shall create a Collateral Pool in favor of Lender. The Collateral Pool shall be
comprised of (i) Security Instruments on the Manufactured Housing Communities
listed on Exhibit A and (ii) any other Security Documents executed by Borrower
pursuant to this Agreement or any other Loan Documents.

         D. Each Security Document shall be cross-defaulted (i.e., a default
under any Security Document, or under this Agreement, shall constitute a default
under each Security Document, and this Agreement) and cross-collateralized
(i.e., each Security Instrument shall secure all of Borrower's obligations under
this Agreement and the other Loan Documents) and it is the intent of the parties
to this Agreement that Lender may accelerate any Note without needing to
accelerate any other Note and that in the exercise of its rights and remedies
under the Loan Documents, Lender may, except as provided in this Agreement,
exercise and perfect any and all of its rights in and under the Loan Documents
with regard to any Mortgaged Property without needing to exercise and perfect
its rights and remedies with respect to any other Mortgaged Property and that
any such exercise shall be without regard to the Allocable Facility Amount
assigned to such Mortgaged Property and that Lender may recover an amount equal
to the full amount outstanding in respect of any of the Notes in connection with
such exercise and any such amount shall be applied as determined by Lender in
its sole and absolute discretion.

         E. Subject to the terms, conditions and limitations of this Agreement,
Lender has agreed to establish the Credit Facility.

                                       1

         NOW, THEREFORE, Borrower and Lender, in consideration of the mutual
promises and agreements contained in this Agreement, hereby agree as follows:

                                    ARTICLE 1

                                 THE COMMITMENT

         SECTION 1.01. The Commitment.

         Subject to the terms, conditions and limitations of this Agreement:

                  (a) Variable Facility Commitment. Lender agrees to make
Variable Advances to Borrower from time to time during the Variable Facility
Availability Period. The aggregate principal balance of the Variable Advances
Outstanding at any time shall not exceed the Variable Facility Commitment. No
Variable Advance shall be made as a result of increases in the Valuation of any
Mortgaged Property; provided, however, Borrower shall not be precluded from
obtaining a release of a Mortgaged Property as otherwise provided herein.
Borrower may re-borrow any part of the Variable Advances which it has previously
borrowed and repaid.

                  (b) Fixed Facility Commitment. Lender agrees to make Fixed
Advances to Borrower from time to time during the Fixed Facility Availability
Period. The aggregate original principal of the Fixed Advances shall not exceed
the Fixed Facility Commitment. No Fixed Advance shall be made as a result of
increases in the Valuation of any Mortgaged Property; provided, however,
Borrower shall not be precluded from obtaining a release of a Mortgaged Property
as otherwise provided herein. The borrowing of a Fixed Advance shall permanently
reduce the Fixed Facility Commitment by the original principal amount of such
Fixed Advance. Borrower may re-borrow as a Variable Advance (but not as a Fixed
Advance) any part of the Fixed Advance which it has previously borrowed and
repaid.

         SECTION 1.02. Requests for Advances.

         Borrower shall request an Advance by giving Lender an Advance Request
in accordance with Section 2.04. The Advance Request shall indicate whether the
Request is for a Fixed Advance, a Variable Advance or both.

         SECTION 1.03. Maturity Date of Advances.

                  (a) Variable Advances. The MBS Issue Date shall be the first
day of a month and the maturity date of the MBS funding each Variable Advance
shall be specified by Borrower in its Advance Request, which date shall be:

                           (i) no earlier than the date which completes three
full months after the MBS Issue Date; and

                           (ii) no later than the date which completes nine full
months after the MBS Issue Date.

                                       2
<PAGE>

         For these purposes, a year shall be deemed to consist of 12 30-day
months. For example, the date which completes three full months after September
1 shall be December 1; and the date which completes three full months after
January 1 shall be April 1.

         No principal payments in respect of any Variable Advance shall be due
prior to the maturity date of such Variable Advance.

                  (b) Fixed Advances. The maturity date of each Fixed Advance
shall be specified by Borrower, provided that such maturity date shall be not
earlier than the 5th anniversary of the making of such Fixed Advance and not
later than the 10th anniversary of the making of such Fixed Advance, provided
that in no event shall the maturity date of any Fixed Advance be later than the
15th anniversary of the Initial Closing Date.

                  (c) Prepayment. Fixed Advances are not prepayable at any time,
provided that, notwithstanding the foregoing, if Borrower has elected yield
maintenance with respect to any Fixed Advance, Borrower (i) may prepay not less
than all of such Fixed Advance during the last six months of the term of such
Fixed Advance, and (ii) may prepay not less than all of such Fixed Advance
pursuant to the yield maintenance provisions of the Fixed Facility Note.

         SECTION 1.04. Interest on Advances.

                  (a) Partial Month Interest. Notwithstanding anything to the
contrary in this Section, if an Advance is not made on the first day of a
calendar month, and the MBS Issue Date is the first day of the month following
the month in which the Advance is made, Borrower shall pay interest on the
original stated principal amount of the Advance for the partial month period
commencing on the Closing Date for the Advance and ending on the last day of the
calendar month in which the Closing Date occurs, (i) for a Variable Advance at a
rate per annum equal to the greater of (1) the Coupon Rate as determined in
accordance with Section 1.05(a) and (2) a rate determined by Lender, based on
Lender's cost of funds and approved in advance, by Borrower, pursuant to the
procedures mutually agreed upon by Borrower and Lender, and (ii) for a Fixed
Advance at a rate, per annum equal to the greater of (1) the interest rate for
the described in subsection (c)(i) of this Section and (2) a rate determined by
Lender, based on Lender's cost of funds, and approved in advance, by Borrower,
pursuant to procedures mutually agreed upon by Borrower and Lender.

<PAGE>

                  (b) Variable Advances.

                           (i) Discount. Each Variable Advance shall be a
discount loan. The original stated principal amount of a Variable Advance shall
be the sum of the Price and the Discount. The Price and Discount of each
Variable Advance shall be determined in accordance with the procedures set out
in Section 2.01. The proceeds of the Variable Advance made available by Lender
to Borrower will equal the original stated principal amount of the Variable
Advance. Borrower shall pay to Lender, in advance of Lender making a Variable
Advance requested by Borrower, the entire Discount for the Variable Advance. On
the maturity of each Variable Advance, the Borrower shall pay the Lender an
amount equal to the original stated principal amount of such Variable Advance.

                           (ii) Variable Facility Fee. In addition to paying the
Discount and the partial month interest, if any, Borrower shall pay monthly
installments of the Variable Facility Fee to Lender for each Variable Advance
from the applicable MBS Issue Date to its maturity date. The Variable Facility
Fee shall be payable in advance, in accordance with the terms of the Variable
Facility Note. The first installment shall be payable on or prior to the Closing
Date for the Variable Advance and shall apply to the first full calendar month
of such MBS. Subsequent installments shall be payable on the first day of each
calendar month, commencing on the first day of the second full calendar month of
such MBS, to its maturity date. Each installment of the Variable Facility Fee
shall be in an amount equal to the product of (1) the Variable Facility Fee, (2)
the original stated principal amount of the Variable Advance, and (3) 1/12.

                  (c) Fixed Advances.

                           (i) Annual Interest Rate. Each Fixed Advance shall
bear interest at a rate, per annum, equal to the sum of (1) the MBS Pass-Through
Rate for such Fixed Advance and (2) the Fixed Facility Fee.

                           (ii) Fixed Facility Fee. In addition to paying the
partial month interest, if any, Borrower shall pay monthly installments of the
MBS Pass-Through Rate and the Fixed Facility Fee to Lender for each Fixed
Advance from the applicable MBS Issue Date to its maturity date. The MBS
Pass-Through Rate and the Fixed Facility Fee shall be payable in arrears, in
accordance with the terms of the Fixed Facility Note. The first installment
shall be payable on the first day of each calendar month, commencing on the
first day of the second full calendar month of such MBS, to its maturity date.
Each installment of the Fixed Facility Fee shall be in an amount equal to the
product of (1) the Fixed Facility Fee, (2) the Outstanding principal balance of
the Fixed Advance, and (3) 1/12.

         SECTION 1.05. Coupon Rates for Advances.

                  (a) Variable Advances. The Coupon Rate shall equal the sum of
(1) an interest rate as determined by Lender (rounded to three places) payable
for the MBS pursuant to the MBS Commitment ("MBS Imputed Interest Rate") and (2)
the Variable Facility Fee.

                                       4
<PAGE>

                  (b) Fixed Advances. The Coupon Rate shall be the rate of
interest applicable to such Fixed Advance pursuant to Section 1.04(c)(i).

         SECTION 1.06. Notes.

                  (a) Variable Advances. The obligation of Borrower to repay
shall be evidenced by the Variable Facility Note. The Variable Facility Note
shall be payable to the order of Lender and shall be made in the amount of the
Variable Facility Commitment.

                  (b) Fixed Advances. The obligation of Borrower to repay shall
be evidenced by the Fixed Facility Notes. The Fixed Facility Notes shall be
payable to the order of Lender and shall be made in the original principal
amount of each Fixed Advance.

         SECTION 1.07. Extension of Variable Facility Termination Date.

         Borrower shall have the right to extend the Variable Facility
Termination Date for one (1) five (5) year period ("Extension") upon
satisfaction of each of the following conditions:

                  (a) Borrower provides written notice requesting the Extension
("Extension Notice") to Lender not less than 90 nor more than 360 days prior to
the then effective Variable Facility Termination Date.

                  (b) No Event of Default or Potential Event of Default exists
on either the date the Extension Notice is given or on the then effective
Variable Facility Termination Date.

                  (c) All of the representations and warranties of Borrower
contained in Article 7 of this Agreement and the other Loan Documents are true
and correct in all material respects on the date the Extension Notice is given
and on the then effective Variable Facility Termination Date, or any such
changes to the truth and accuracy of such representations and warranties shall
not have had a Material Adverse Effect on the Borrower or any of the Mortgaged
Properties.

                  (d) Borrower is in compliance with all of the covenants
contained in Articles 8 and 9 on the date the Extension Notice is given and on
the then effective Variable Facility Termination Date.

         Upon receipt of the Extension Notice and upon compliance with
conditions set forth above, the Variable Facility Termination Date shall be
extended for five (5) years on the terms and conditions contained in this
Agreement and the other Loan Documents. The Variable Facility Fee and the
Standby Fee applicable to the Variable Facility during the Extension shall be as
determined by Lender, pursuant to the terms of this Agreement.

         SECTION 1.08. Conversion from Variable Facility Commitment to Fixed
Facility Commitment.

         Except as provided in Section 1.09, Borrower shall have the right, from
time to time during the Fixed Facility Availability Period, to convert all or
any portion of the Variable Facility Commitment to the Fixed Facility
Commitment. The Variable Facility Commitment

                                       5
<PAGE>

shall be reduced by, and the Fixed Facility Commitment shall be increased by,
the amount of each conversion.

                  (a) Request. To convert all or a portion of the Variable
Facility Commitment to the Fixed Facility Commitment, Borrower shall deliver a
Conversion Request to Lender. Each Conversion Request shall designate (1) the
amount of the conversion and (2) any Variable Advances Outstanding which will be
prepaid on or before the Closing Date for the conversion as required by Section
1.09(c). If, after Lender determines the interest rate to be applicable to the
Fixed Loan after conversion, Borrower elects not to proceed with the conversion,
it shall so notify Lender in writing. If Borrower revokes any Conversion Request
pursuant to the preceding sentence, it shall be responsible for the reasonable
costs and expenses incurred by Lender in connection with such Conversion
Request.

                  (b) Closing. Subject to Section 1.09 and provided that all
conditions contained in Section 1.10 are satisfied, Lender shall permit the
requested conversion to close at offices designated by Lender on a Closing Date
selected by Lender, and occurring within 30 Business Days after Lender's receipt
of the Conversion Request (or on such other date as Borrower and Lender may
agree). At the closing, Lender and Borrower shall execute and deliver, at the
sole cost and expense of Borrower, in form and substance satisfactory to Lender,
the Conversion Documents.

         SECTION 1.09. Limitations on Right to Convert.

         Borrower's right to convert all or any portion of the Variable Facility
Commitment to the Fixed Facility Commitment is subject to the following
limitations:

                  (a) Closing Date. The Closing Date shall occur during the
Fixed Facility Availability Period.

                  (b) Minimum Request. Each Conversion Request shall be in the
minimum amount of $5,000,000.

                  (c) Obligation to Prepay Variable Advances. Borrower shall
prepay any difference by which, after the conversion, the aggregate unpaid
principal balance of all Variable Advances Outstanding will exceed the Variable
Facility Commitment. No Facility Termination Fee shall be due in connection with
any Conversion.

         SECTION 1.10. Conditions to Conversion.

         The conversion of all or any portion of the Variable Facility
Commitment to the Fixed Facility Commitment is subject to the satisfaction, on
or before the Closing Date, of (a) the conditions precedent contained in Section
6.08 and (b) all applicable General Conditions contained in Section 6.01.

                                       6

                                    ARTICLE 2

                                  THE ADVANCES

         SECTION 2.01. Rate Setting for an Advance.

         Rates for an Advance shall be set in accordance with the following
procedures:

                  (a) Preliminary, Nonbinding Quote. At Borrower's request
Lender shall quote an estimate of the MBS Pass-Through Rate (for a proposed
Fixed Advance) or MBS Imputed Interest Rate (for a proposed Variable Advance).
Lender's quote shall be based on (1) a solicitation of bids from institutional
investors selected by Lender and (2) the proposed terms and amount of the
Advance selected by Borrower. The quote shall not be binding upon Lender.

                  (b) Rate Setting. If Borrower satisfies all of the conditions
to Lender's obligation to make the Advance, then Borrower may submit to Lender,
by facsimile transmission before 1:00 p.m. Washington, D.C. time on any Business
Day ("Rate Setting Date"), a completed and executed Rate Form. The Rate Form
shall specify the amount, term, MBS Issue Date, Facility Fee, the proposed
maximum Coupon Rate ("Maximum Annual Coupon Rate") and Closing Date for the
Advance.

                  (c) Rate Confirmation. Within one Business Day after receipt
of the Rate Form, Lender shall solicit bids from institutional investors
selected by Lender based on the information in the Rate Form and, provided the
actual Coupon Rate (if the low bid were accepted) would be at or below the
Maximum Annual Coupon Rate, shall obtain a commitment ("MBS Commitment") for the
purchase of an MBS having the bid terms described in the related Rate Form.
Lender shall then complete and countersign the Rate Form thereby confirming the
amount, term, MBS Issue Date, MBS Delivery Date, MBS Imputed Interest Rate or
MBS Pass-Through Rate, Facility Fee, Coupon Rate, Discount, Price, and Closing
Date for the Advance and shall immediately deliver by facsimile transmission the
Rate Form to Borrower.

         SECTION 2.02. Advance Confirmation Instrument for Variable Advances.

         On or before the Closing Date for a Variable Advance, Borrower shall
execute and deliver to Lender a fully executed Advance Confirmation Instrument,
confirming the amount, term, MBS Issue Date, MBS Delivery Date, MBS Imputed
Interest Rate, Variable Facility Fee, Coupon Rate, Discount, Price and Closing
Date for the Advance, and Borrower's obligation to repay the Variable Advance in
accordance with the terms of the Variable Facility Note and this Agreement. Upon
the funding of the Variable Advance, Lender shall insert the date of funding on
the Advance Confirmation Instrument and deliver a copy of the completed Advance
Confirmation Instrument to Borrower to evidence the date of funding and to
confirm that the Advance Confirmation Instrument is not effective until the date
of funding. Lender's failure to do so shall not invalidate the Advance
Confirmation Instrument or otherwise affect in any way any obligation of
Borrower to repay Variable Advances in accordance with the Advance Confirmation
Instrument, the Variable Facility Note or the other Loan Documents.

                                       7
<PAGE>

         SECTION 2.03. Breakage and other Costs.

         If Lender obtains, and then fails to fulfill, the MBS Commitment
because the Advance is not made (for a reason other than Lender's default),
Borrower shall pay all reasonable out-of-pocket costs payable to the potential
investor and other reasonable costs, fees and damages incurred by Lender in
connection with its failure to fulfill the MBS Commitment.

         SECTION 2.04. Advances.

         Borrower may deliver an Advance Request to Lender.

                  (a) If the Advance Request is to obtain the Initial Advance
and all conditions precedent contained in Section 6.02 and the General
Conditions contained in Section 6.01 are satisfied on or before the Closing Date
for the Initial Advance, Lender shall make the Initial Advance on the Initial
Closing Date or on such other date as Borrower and Lender may agree.

                  (b) If the Advance Request is to obtain a Future Advance, such
Advance Request shall be in the minimum amount of $3,000,000. Borrower may have
one or more Advances of not less than $3,000,000 even though such Advances are
made on the same day and mature on the same date. If all conditions precedent
contained in Section 6.03 and the General Conditions contained in Section 6.01
are satisfied, Lender shall make the requested Future Advance, at a closing to
be held at offices designated by Lender on a Closing Date selected by Lender,
which date shall be not more than three (3) Business Days after Borrower's
receipt from Lender of the confirmed Rate Form (or on such other date as
Borrower and Lender may agree).

         SECTION 2.05. Determination of Allocable Facility Amount and
Valuations.

                  (a) Initial Determinations. On the Initial Closing Date,
Lender shall determine (i) the Allocable Facility Amount and Valuation for each
Mortgaged Property and (ii) the Aggregate Debt Service Coverage Ratio and the
Aggregate Loan to Value Ratio. The determinations of Allocable Facility Amounts
and Valuations made as of the Initial Closing Date shall remain unchanged until
the first anniversary of the Initial Closing Date.

                  (b) Monitoring Determinations. (i) Once each calendar month
or, if the Commitment consists only of a Fixed Facility Commitment, once each
Calendar Year, within 20 Business Days after Borrower has delivered to Lender
the reports required in Section 8.03, Lender shall determine the Aggregate Debt
Service Coverage Ratio and the Aggregate Loan to Value Ratio and calculations
required in connection with the other covenants set forth in the Loan Documents,
and whether the Borrower is in compliance, (ii) after the First Anniversary, on
an annual basis, and if Lender reasonably decides that changed market or
property conditions warrant, Lender shall determine Allocable Facility Amounts
and Valuations, (iii) Lender shall also redetermine Allocable Facility Amounts
to take account of any addition, release or substitution of Collateral or other
event which invalidates the outstanding determinations. In determining
Valuations, Lender shall use the then current Cap Rates. Until redetermined, the
outstanding Allocable Facility Amounts and Valuations shall remain in effect.
During the first Loan Year a Mortgaged Property is in the Collateral Pool, all
calculations of Aggregate Debt

                                       8
<PAGE>
Service Coverage and Aggregate Loan to Value Ratios including such Mortgaged
Property shall be based on actual operations of such Mortgaged Property during
the period the Mortgaged Property was in the Collateral Pool and underwriting
proforma results for the remainder of such Loan Year.

                                    ARTICLE 3

                               COLLATERAL CHANGES

         SECTION 3.01. Right to Add Collateral.

         Subject to the terms and conditions of this Article, Borrower shall
have the right, from time to time during the Term of this Agreement, to add
Manufactured Housing Communities to the Collateral Pool.

         SECTION 3.02. Procedure for Adding Collateral.

         The procedure for adding Collateral contained in this Section 3.02
shall apply to all additions of Collateral including, but not limited to,
additions of Collateral in connection with substitutions of Collateral and
expansion of the Credit Facility.

                  (a) Request. Borrower may deliver to Lender an Addition
Request to add one or more Manufactured Housing Communities to the Collateral
Pool. Each Addition Request shall be accompanied by the following: (i) the
information required by the DUS Guide Underwriting Requirements including any
Lender memoranda relating to Manufactured Housing Communities issued by Fannie
Mae from time to time and any additional information Lender may reasonably
request; and (ii) the payment of all Additional Collateral Due Diligence Fees.

                  (b) Underwriting. Lender shall evaluate the proposed
Additional Mortgaged Property in accordance with the DUS Guide Underwriting
Requirements including any Lender memoranda relating to Manufactured Housing
Communities issued by Fannie Mae from time to time, and shall make underwriting
determinations as to the Aggregate Debt Service Coverage Ratio and the Aggregate
Loan to Value Ratio applicable to the Collateral Pool on the basis of the lesser
of (1) the acquisition price of the proposed Additional Mortgaged Property if
purchased as a single acquisition or a reasonable allocation of total purchase
price if purchased as part of a portfolio purchase by Borrower within 12 months
of the related Addition Request, and (2) a Valuation made with respect to the
proposed Additional Mortgaged Property. Within 30 Business Days (provided that
Lender shall use reasonable efforts to respond sooner) after receipt of (1) the
Addition Request and (2) all reports, certificates and documents required by the
DUS Guide Underwriting Requirements including any Lender memoranda relating to
Manufactured Housing Communities issued by Fannie Mae from time to time,
including a zoning analysis undertaken in accordance with Section 206 of Part
III of the DUS Guide, Lender shall notify Borrower whether it shall consent to
the Addition Request. If Lender consents it shall set forth the Aggregate Debt
Service Coverage Ratio and the Aggregate Loan to Value Ratio which it estimates
shall result from the addition of the proposed Additional Mortgaged Property.
Within

<PAGE>

30 Business Days after receipt of Lender's consent to the Addition Request,
Borrower shall notify Lender whether it elects to add the proposed Additional
Mortgaged Property to the Collateral Pool. If Borrower fails to respond within
the period of 30 Business Days, it shall be conclusively deemed to have elected
not to add the proposed Additional Mortgaged Property to the Collateral Pool.

                  (c) Closing. If Lender consents to the Addition Request,
Borrower timely elects to add the proposed Additional Mortgaged Property to the
Collateral Pool and all conditions precedent contained in Section 6.04 and all
General Conditions contained in Section 6.01 are satisfied, Lender shall permit
the addition of the proposed Additional Mortgaged Property to the Collateral
Pool, at a closing to be held at offices designated by Lender on a Closing Date
selected by Lender, occurring within 20 Business Days after Lender's receipt of
Borrower's election (or on such other date as Borrower and Lender may agree).

         SECTION 3.04. Procedure for Obtaining Releases of Collateral.

                  (a) Request. To obtain a release of Collateral from the
Collateral Pool, Borrower may deliver a Release Request to Lender. The Release
Request shall not result in a termination of all or any part of the Credit
Facility. Borrower may terminate all or any part of the Credit Facility only by
delivering a Facility Termination Request or Credit Facility Termination Request
pursuant to Article 5.

                  (b) Closing. If all conditions precedent contained in Section
6.05 and all General Conditions contained in Section 6.01 are satisfied, Lender
shall cause the Release Property to be released, at a closing to be held at
offices designated by Lender on a Closing Date selected by Lender, and occurring
not less than 15 days after Lender's receipt of the Release Request (or on such
other date as Borrower and Lender may agree), by executing and delivering, and
causing all applicable parties to execute and deliver, all at the sole cost and
expense of Borrower, the Release Documents. Borrower shall prepare the Release
Documents and submit them to Lender for its review.

                  (c) Release Price. The Release Price for each Mortgaged
Property shall be (A) the greater of (i) 110% of the Allocable Facility Amount
for the Release Property and (ii) the amount of any Advances Outstanding which
are required to be repaid by Borrower to Lender so that, immediately after the
release, the Aggregate Debt Service Coverage Ratio immediately prior to the
release is not reduced and the Aggregate Loan to Value Ratio immediately prior
to the release is not increased, or (B) if after the release of the Release
Property, the Aggregate Loan to Value Ratio is 55% or less and the Aggregate
Debt Service Coverage Ratio is 1.55:1.0 or greater, then the Release Price, if
any, shall be the amount of any Advances Outstanding which are required to be
repaid by Borrower to Lender so that, immediately after the release, the
Aggregate Debt Service Coverage Ratio is no less than 1.55:1.0 and the Aggregate
Loan to

                                       10
<PAGE>

Value Ratio is no more than 55%. In addition, Borrower shall pay to Lender all
other amounts due under the Notes and any Advance Confirmation Instruments
evidencing the Advances being repaid.

                  (d) Application of Release Price. The Release Price shall be
applied first against the Variable Advances Outstanding until there are no
further Variable Advances Outstanding, then against the prepayment of Fixed
Advances Outstanding, so long as the prepayment is permitted under the
applicable Fixed Facility Note. If, on the date Borrower pays the Release Price,
Variable Advances are Outstanding but not then due and payable, Lender shall
hold the Release Price in an interest-bearing account as additional Collateral,
until the next date on which Variable Advances are due and payable, at which
time Lender shall apply the appropriate portion of the Release Price to such
Variable Advances.

         SECTION 3.05. Right to Substitute Collateral.

         Subject to the terms, conditions and limitations of this Section 3.05,
Borrower shall have the right to add one or more Manufactured Housing
Communities to the Collateral Pool in substitution of one or more Mortgaged
Properties then in the Collateral Pool ("Substitute Mortgaged Property").

         SECTION 3.06. Procedure for Substituting Collateral.

                  (a) Request. Borrower may deliver to Lender a Substitution
Request to add one or more Manufactured Housing Communities in substitution of
one or more Mortgaged Properties then in the Collateral Pool. Each Substitution
Request shall be accompanied by

                           (i) the information required by the DUS Guide
Underwriting Requirements including any Lender memoranda relating to
Manufactured Housing Communities issued by Fannie Mae from time to time and any
additional information Lender may reasonably request; and (ii) a statement
whether the addition of the Substitute Mortgaged Property will occur
simultaneously with the release of the Release Property and, if not, the
proposed date on which the Substitute Mortgaged Property will be added to the
Collateral Pool which, in no event, shall be a date which is more than 90 days
after the proposed date of the release of the Release Property.

                  (b) Underwriting. Lender shall make underwriting
determinations as to the Aggregate Debt Service Coverage Ratio and the Aggregate
Loan to Value Ratio immediately prior to and immediately after giving effect to
the proposed substitution, and the Valuation and the Net Operating Income for
both the Substitute Mortgaged Property and the Release Property. Notwithstanding
anything to the contrary contained herein, underwriting determinations with
respect to the proposed Substitute Mortgaged Property shall be made on the basis
of a Valuation and otherwise in accordance with the DUS Guide Underwriting
Requirements including any Lender memoranda relating to Manufactured Housing
Communities issued by Fannie Mae from time to time. Within 30 days after receipt
of (i) the Substitution Request and (ii) all reports, certificates and documents
required under the DUS Guide including any Lender memoranda relating to
Manufactured Housing Communities issued by Fannie Mae from time to time,

                                       11
<PAGE>

including a zoning analysis undertaken in accordance with Section 206 of Part
III of the DUS Guide, Lender shall notify Borrower whether Lender shall consent
to Substitution Request. If Lender consents, it shall set forth the Aggregate
Debt Service Coverage Ratio and the Aggregate Loan to Value Ratio which it
estimates shall result from the substitution of the Substitute Mortgaged
Property into the Collateral Pool. Within 30 days after receipt of Lender's
consent notice, Borrower shall notify Lender whether it elects to cause such
substitution to occur. If Borrower fails to respond within the period of 30
days, it shall be conclusively deemed to have elected not to cause the proposed
substitution to occur.

                  (c) Closing. If Lender consents to the Substitution Request,
Borrower timely elects to cause such substitution to occur and all conditions
precedent contained in Section 6.06 and all General Conditions contained in
Section 6.01 are satisfied, Lender shall permit the Substitute Mortgaged
Property to be substituted into the Collateral Pool in replacement of the
Release Property, at a closing to be held at offices designated by Lender on a
Closing Date selected by Lender and approved by Borrower, and occurring

                           (i) if the addition of the Substitute Mortgaged
Property and the release of the Release Property are to occur simultaneously,
within 30 days after Lender's receipt of Borrower's election (or on such other
date as Borrower and Lender may agree); or

                           (ii) if the addition of the Substitute Mortgaged
Property is to occur subsequent to the release of the Release Property, within
90 days after the release of the Release Property.

  If, in the case of clause (ii) of this paragraph, the addition of the
  Substitute Mortgaged Property to the Collateral Pool does not occur within 90
  days or such longer period as approved by Lender, in its sole discretion,
  after the release of the Release Property, then Borrower shall have waived its
  right to substitute such Release Property with the Substitute Mortgaged
  Property, the Release Price shall be determined pursuant to Section 3.04(c)
  and Borrower shall comply with the requirement contained in Section 3.04(d).
  Such Release Price, or the applicable portion thereof, shall be immediately
  due and payable by Borrower to Lender to reduce the Advances Outstanding as
  required by, and in the manner contained in, Section 3.04(d).

                  (d) Restriction on Borrowings. If the addition of the
Substitute Mortgaged Property and the release of the Release Property does not
occur simultaneously then, until the addition of the Substitute Mortgaged
Property, the aggregate unpaid principal balance of Advances Outstanding shall
not exceed the amount of the then-existing Commitment minus the Allocable
Facility Amount of the Release Property, unless Borrower has delivered
additional Collateral reasonably acceptable to Lender in an amount at least
equal to such Allocable Facility Amount. If the aggregate unpaid principal
balance of Advances Outstanding exceeds such amount (and satisfactory additional
Collateral has not been delivered by Borrower to Lender), Borrower shall pay
such excess as a condition precedent to the addition of a Substitute Mortgaged
Property. Notwithstanding the foregoing, in no event shall the value of the
additional Collateral exceed 15% of the principal balance of the Advances
Outstanding. Any payment received by Lender under this Section shall be applied
against Advances Outstanding in the manner prescribed for Release Prices
pursuant to Section 3.04(d). The additional Collateral shall

                                       12
<PAGE>

be released to Borrower upon the addition of the applicable Substitute Mortgaged
Property to the Collateral Pool.

         SECTION 8.10. Loan Document Taxes.

         If any tax, assessment or Imposition (other than a franchise tax,
excise tax or income tax imposed on or measured by, the net income or capital
(including branch profits tax) of Lender (or any transferee or assignee thereof,
including a participation holder)) ("Loan Document Taxes") is levied, assessed
or charged by the United States, or any State in the United States, or any
political subdivision or taxing authority thereof or therein upon any of the
Loan Documents or the obligations secured thereby, the interest of Lender in the
Mortgaged Properties, or Lender by reason of or as holder of the Loan Documents
arising in connection with the Credit Facility, Borrower shall pay all such Loan
Document Taxes to, for, or on account of Lender (or provide funds to Lender for
such payment, as the case may be) as they become due and payable and shall
promptly furnish proof of such payment to Lender, as applicable. In the event of
passage of any law or regulation permitting, authorizing or requiring such Loan
Document Taxes to be levied, assessed or charged, which law or regulation in the
opinion of counsel to Lender may prohibit Borrower from paying the Loan Document
Taxes to or for Lender, Borrower shall enter into such further instruments as
may be permitted by law to obligate Borrower to pay such Loan Document Taxes to
the extent provided herein.

and continuation statements and such other instruments and take such further
action as Lender from time to time may request as reasonably necessary,
desirable or proper to carry out more effectively the purposes of this Agreement
or any of the other Loan Documents or to subject the Collateral to the lien and
security interests of the Loan Documents or to evidence, perfect or otherwise
implement, to assure the lien and security interests intended by the terms of
the Loan Documents or in order to exercise or enforce its rights under the Loan
Documents, provided the foregoing does not materially increase Borrower's
obligations or materially decrease its rights hereunder.

         SECTION 8.12. Transfer of Ownership Interest of Borrower and Sun .

                  (a) Prohibition on Transfers. Subject to paragraph (b) of this

Change of Control.

                  (b) Permitted Transfers. Notwithstanding the provisions of

                           (iv) The issuance by Borrower or Sun of additional
member interests or stock, as the case may be, and the subsequent Transfer of
such interest; provided, however, that no Change in Control occurs as the result
of such Transfer.

                           (v) A merger with or acquisition of another entity by
Borrower or Sun, provided that (A) Borrower or Sun, as the case may be, is the
surviving entity after such merger or acquisition, (B) no Change in Control
occurs, and (C) such merger or acquisition does not result in an Event of
Default, as such terms are defined in this Agreement.

                           (vi) A Transfer of a Mortgaged Property to one or
more, direct or indirect, wholly owned Affiliate of Sun or the OP, so long as
such entity meets the requirements of a "Borrower" under this Agreement, makes
the representations and warranties made by the Borrower under this Agreement,
and executes such documents as Lender may reasonably require to evidence such
entity's obligations under the Loan Documents.

                           (vii) A Transfer to an Approved Acquiring Person, so

principal balance of the Advances then in effect.

                           (viii) A Transfer of interests in Sun on public stock
exchanges, provided no Change of Control occurs.

         In connection with any permitted Transfer submitted to Lender for
review, Borrower shall reimburse Lender for all of Lender's reasonable
out-of-pocket costs (including reasonable attorneys' fees) incurred in reviewing
and documenting the Transfer request.

                  (c) Consent to Prohibited Transfers. Lender may, in its sole
and absolute discretion, consent to a Transfer that would otherwise violate this

                           (iii) 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 Borrower, Sun or the OP, as the case may be, in
connection with the origination or purchase of similar mortgages, deeds of trust
or deeds to secure debt on multifamily properties;

                                       31
<PAGE>

                           (iv) in the case of a Transfer of direct or indirect
ownership interests in Borrower, Sun or the OP, as the case may be, if
transferor or any other person has obligations under any Loan Documents, the
execution by the transferee of one or more individuals or entities acceptable to
Lender of an assumption agreement 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;

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

                  out-of-pocket costs (including reasonable attorneys' fees)
                  incurred in reviewing and documenting the Transfer request.

         SECTION 8.13. Transfer of Ownership of Mortgaged Property.

on, the Advances and all other sums owing by Borrower to Lender under any of the
Loan Documents forthwith due and payable, whereupon the Commitment will
terminate and the principal of, and interest on, the Advances and all other sums
owing by Borrower to Lender under any of the Loan Documents will become
forthwith due and payable.

                  (b) Lender shall have the right to pursue any other remedies
available to it under any of the Loan Documents.

                  (c) Lender shall have the right to pursue all remedies
available to it at law or in equity, including obtaining specific performance
and injunctive relief.

         SECTION 12.02. Waivers; Rescission of Declaration.

         Lender shall have the right, to be exercised in its complete
discretion, to waive any breach hereunder (including the occurrence of an Event
of Default), by a writing setting forth the terms, conditions, and extent of
such waiver signed by Lender and delivered to Borrower. Unless such writing
expressly provides to the contrary, any waiver so granted shall extend only to
the specific event or occurrence which gave rise to the waiver and not to any
other similar event or occurrence which occurs subsequent to the date of such
waiver.

         SECTION 12.03. Lender's Right to Protect Collateral and Perform
Covenants and Other Obligations.

         If Borrower or Sun fails to perform the covenants and agreements
contained in this Agreement or any of the other Loan Documents, then Lender at
Lender's option may make such appearances, disburse such sums and take such
action as Lender deems reasonably necessary, in its sole discretion, to protect
Lender's interest, including (i) disbursement of reasonable attorneys' fees,
(ii) entry upon the Mortgaged Property to make repairs and replacements, (iii)
procurement of satisfactory insurance as provided in the Security Instrument
encumbering the Mortgaged Property, and (iv) if the Security Instrument is on a
leasehold, exercise of any option to renew or extend the ground lease on behalf
of Borrower and the curing of any default of Borrower in the terms and
conditions of the ground lease. Any amounts disbursed by Lender pursuant to this
Section, with interest thereon, shall become additional indebtedness of Borrower
secured by the Loan Documents. Unless Borrower and Lender agree to other terms
of payment, such amounts shall be immediately due and payable and shall bear
interest from the date of disbursement at the weighted average, as determined by
Lender, of the interest rates in effect from time to time for each Advance
unless collection from Borrower of interest at such rate would be contrary to
applicable law, in which event such amounts shall bear interest at the highest
rate which may be collected from Borrower under applicable law. Nothing
contained in this Section shall require Lender to incur any expense or take any
action hereunder.

         SECTION 12.04. No Remedy Exclusive.

                                       39
<PAGE>

Unless otherwise expressly provided, no remedy herein conferred upon or reserved
is intended to be exclusive of any other available remedy, but each remedy shall
be cumulative and shall be in addition to other remedies given under the Loan
Documents or existing at law or in equity.

         SECTION 12.05. No Waiver.

         No delay or omission to exercise any right or power accruing under any
Loan Document upon the happening of any Event of Default or Potential Event of
Default shall impair any such right or power or shall be construed to be a
waiver thereof, but any such right and power may be exercised from time to time
and as often as may be deemed expedient.

         SECTION 12.06. No Notice.

         To entitle Lender to exercise any remedy reserved to Lender in this
Article, it shall not be necessary to give any notice, other than such notice as
may be required under the applicable provisions of this Agreement, any of the
other Loan Documents or Applicable Law.

                                   ARTICLE 13

                              RIGHTS OF FANNIE MAE

         SECTION 13.01. Special Pool Purchase Contract.

         Borrower acknowledges that Fannie Mae is entering into an agreement
with Lender ("Special Pool Purchase Contract"), pursuant to which, inter alia,
(i) Lender shall agree to assign all of its rights under this Agreement to
Fannie Mae, (ii) Fannie Mae shall accept the assignment of the rights, (iii)
subject to the terms, limitations and conditions contained in the Special Pool
Purchase Contract, Fannie Mae shall agree to purchase a 100% participation
interest in each Advance issued under this Agreement by issuing to Lender an
MBS, in the amount and for a term equal to the Advance purchased and backed by
an interest in the Fixed Facility Note or the Variable Facility Note, as the
case may be, and the Collateral Pool securing the Notes, (iv) Lender shall agree
to assign to Fannie Mae all of Lender's interest in the Notes and Collateral
Pool securing the Notes, and (v) Lender shall agree to service the loans
evidenced by the Notes.

         SECTION 13.02. Assignment of Rights.

         Borrower acknowledges and consents to the assignment to Fannie Mae of
all of the rights of Lender under this Agreement and all other Loan Documents,
including the right and power to make all decisions on the part of Lender to be
made under this Agreement and the other Loan Documents, but Fannie Mae, by
virtue of this assignment, shall not be obligated to perform the obligations of
Lender under this Agreement or the other Loan Documents.

         SECTION 13.03. Release of Collateral.

         Borrower hereby acknowledges that, after the assignment of Loan
Documents contemplated in Section 13.02, Lender shall not have the right or
power to effect a release of any

                                       40
<PAGE>

Collateral pursuant to Article 6. Borrower acknowledges that the Security
Instruments provide for the release of the Collateral under Articles 3 and 5.
Accordingly, Borrower shall not look to Lender for performance of any
obligations contained in Articles 3 and 5, but shall look solely to the party
secured by the Collateral to be released for such performance. Lender represents
and warrants to Borrower that the party secured by the Collateral shall be
subject to the release provisions contained in Articles 3 and 5 by virtue of the
release provisions in each Security Instrument.

         SECTION 13.04. Replacement of Lender.

         At the request of Fannie Mae, Borrower and Lender shall agree to the
assumption by another lender designated by Fannie Mae (which lender shall meet
Fannie Mae's then current standards for lenders for credit facilities of the
type and size of the credit facility evidenced by this Agreement), of all of the
obligations of Lender under this Agreement and the other Loan Documents, and/or
any related servicing obligations, and, at Fannie Mae's option, the concurrent
release of Lender from its obligations under this Agreement and the other Loan
Documents, and/or any related servicing obligations, and shall execute all
releases, modifications and other documents which Fannie Mae determines are
necessary or desirable to effect such assumption, all without material cost to
Borrower.

         SECTION 13.05. Fannie Mae and Lender Fees and Expenses.

         Borrower agree that any provision providing for the payment of fees,
costs or expenses incurred or charged by Lender pursuant to this Agreement shall
be deemed to provide for Borrower's payment of all reasonable fees, costs and
expenses incurred or charged by Lender or Fannie Mae in connection with the
matter for which fees, costs or expenses are payable.

         SECTION 13.06. Third-Party Beneficiary.

         Borrower hereby acknowledge and agree that Fannie Mae is a third party
beneficiary of all of the representations, warranties and covenants made by
Borrower to, and all rights under this Agreement conferred upon, Lender, and, by
virtue of its status as third-party beneficiary and/or assignee of Lender's
rights under this Agreement, Fannie Mae shall have the right to enforce all of
the provisions of this Agreement against Borrower.

                                   ARTICLE 14

              INSURANCE, REAL ESTATE TAXES AND REPLACEMENT RESERVES

         SECTION 14.01. Insurance and Real Estate Taxes.

         Borrower shall establish funds for taxes, insurance premiums and
certain other charges for each Mortgaged Property in accordance with Section
7(a) of the Security Instrument for each Mortgaged Property.

         SECTION 14.02. Replacement Reserves.

                                       41

         Borrower shall execute a Replacement Reserve Agreement for the
Mortgaged Property which they own and shall (unless waived by Lender by separate
agreement) make all deposits for replacement reserves in accordance with the
terms of the Replacement Reserve Agreement.

                       PERSONAL LIABILITY OF THE BORROWER

         SECTION 15.01. Personal Liability of Borrower.

                           (a) Limits on Personal Liability. Except as otherwise
                  provided in this Article, the personal liability of the
                  Borrower under this Agreement or any other Loan Document for
                  the performance of any Obligations of the Borrower under the
                  Loan Documents shall be limited to an amount equal to 25% of
                  the amount of the Variable Advances Outstanding minus the
                  notional amount of any Cap purchased by the Borrower pursuant
                  to Article 16 of this Agreement (the "Guaranteed Amount"), and
                  the Lender's only recourse for the payment and performance of
                  the Obligations in excess of such amount shall be the Lender's
                  exercise of its rights and remedies with respect to the
                  Mortgaged Properties and any other Collateral held by the
                  Lender as security for the Obligations. Notwithstanding the
                  foregoing, no general partner of Borrower shall have personal
                  liability under this Section 15.01(a) (unless such general
                  partner is a guarantor under the Guaranty). The Borrower shall
                  not be liable for the Guaranteed Amount if, prior to August
                  29, 2002, the Borrower provides a Cap having a notional amount
                  equal to the entire amount of Variable Advances Outstanding as
                  provided for in Section 16.01 of this Agreement. This
                  limitation on the Borrower's liability shall not impair the
                  Lender's enforcement of its rights set forth in the Guaranty.

                           (b) Exceptions to Limits on Personal Liability. In
                  addition to amounts the Borrower is personally liable for
                  pursuant to paragraph (a) above, the Borrower (but not any
                  general partner of Borrower [unless such general partner is a
                  guarantor under the Guaranty]) shall be personally liable to
                  Lender for an amount 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 the Security Instrument encumbering
                  the Mortgaged Property and the amount of all security deposits
                  collected by Borrower; (2) failure of Borrower to apply all
                  insurance proceeds, condemnation proceeds or security deposits
                  from tenants as required by the Security Instrument
                  encumbering the Mortgaged Property; (3) fraud or written
                  material misrepresentation (at the time made) by Borrower or
                  any officer, director, partner, member or employee of Borrower
                  in connection with the application for or creation of the
                  Obligations or any request for any action or consent by
                  Lender; (4) failure to apply Rents, first, to the payment of
                  reasonable operating expenses and then to amounts ("Debt
                  Service Amounts") payable under the Loan Documents, provided
                  that prior to such application, Rents may be commingled with
                  other funds of Sun or its Affiliates (except that Borrower
                  will not be

                                       42
<PAGE>

                  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 of a Mortgaged Property that are
                  distributed in any Calendar Quarter if Borrower has paid all
                  operating expenses and Debt Service Amounts for that Calendar
                  Quarter); (5) a Final Loss with respect to the Obligations
                  upon the filing of a voluntary petition in a Bankruptcy
                  proceeding by the Borrower, Sun or the OP or the filing of an
                  involuntary proceeding in Bankruptcy against the Borrower, Sun
                  or the OP or an Affiliate thereof by Borrower, Sun or the OP
                  or an Affiliate thereof; (6) Borrower's acquisition of any
                  property or operation of any business not permitted by Section
                  33 of any Security Instrument; (7) a Transfer that is not a
                  Permitted Transfer of Mortgaged Properties or a Permitted
                  Transfer of Ownership Interests; or (8) any and all
                  indemnification obligations contained in Section 18 of any
                  Security Instrument.

                           (c) Miscellaneous. To the extent that Borrower has
                  personal liability under this Section, such liability shall be
                  joint and several with that of Sun under the Guaranty and
                  Lender may exercise its rights against Borrower or Sun
                  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 the Loan Documents or
                  applicable law.

                                   ARTICLE 16

                            INTEREST RATE PROTECTION

         At Borrower's option, prior to August 29, 2002, Borrower may elect to
provide a Cap having a notional amount equal to an amount up to the amount of
the Variable Advances Outstanding. If Borrower elects to provide a Cap as
provided above, the following terms and conditions shall be applicable.

         SECTION 16.01. Interest Rate Protection.

                  (a) The Initial Cap. Any Cap relating to a Variable Advance
Outstanding on the date the Cap is purchased (which shall not be later than
August 29, 2002) shall be in place for a period beginning on the date such Cap
is purchased and ending not earlier than the date which is three years from the
purchase of such Cap (the "Initial Cap Period").

                  (b) Subsequent Caps. Subject to the other terms of Article 16,
additional Caps (each, a "Subsequent Cap") shall be purchased by Borrower (i)
upon the expiration of the Cap in place for the Initial Cap Period, and (ii) if
elected by the Borrower, at the time any Additional Variable Advance is made.
Any Subsequent Cap purchased pursuant to the preceding sentence shall be in
effect for a period beginning on the date of the expiration of the initial Cap
or Closing Date of the Future Advance Request, as the case may be, and ending on
the Variable Facility Termination Date or, if shorter, three (3) years from the
Closing Date of the Future Advance

                                       43
<PAGE>

Request. If the Variable Facility Termination Date is extended pursuant to
Section 1.07 of this Agreement, the Borrower shall obtain Subsequent Caps
pursuant to this Article 16 for a period for the shorter of (i) three years and
(ii) the period ending on the Variable Facility Termination Date. It is the
intention of the parties, and a condition of the Variable Facility Commitment,
that the Borrower shall obtain, and shall maintain at all times during the term
of this Agreement so long as there are any Variable Facility Advances
Outstanding, a Cap or Caps in an aggregate notional principal amount equal to
the portion of the Variable Advances Outstanding elected by the Borrower
pursuant to this Article 16 and covering the entire term of the Variable
Facility Commitment and meeting the conditions set forth in Section 16.02. If
the Variable Advances Outstanding decrease, the Borrower may amend the Cap or
Caps to provide for a decrease in the notional amount to an amount equal to the
reduced amount of the Variable Facility Commitment, provided that the Lender
gives its prior written approval to the documents reflecting the amendment
(which approval shall not be unreasonably withheld, delayed or conditioned). If
the Aggregate Debt Service Coverage Ratio increases at the end of the period
ending at the end of the second Loan Year, the Borrower may amend or replace the
Cap or Caps to provide an amended or substitute Cap or Caps that meet the
requirements of Section 16.02, provided that the Lender gives its prior written
approval to the documents reflecting the amendment to the Cap or Caps or
substitute Cap or Caps, which approval shall not be unreasonably withheld,
delayed or conditioned.

         SECTION 16.02. Cap Terms.

         Each Cap shall:

         (i) together with all other Caps in place, provide for a notional
         principal amount equal at all times to the outstanding principal
         balance of the Variable Facility Commitment for which the Borrower has
         elected to provide a Cap;

         (ii) be in effect at the time of its purchase for not less than the
         shorter of (a) the entire term of the Variable Facility Commitment and
         (b) three (3) years;

         (iii) provide for a notional interest rate equal to not less than the
         lowest interest rate that would result in an Aggregate Debt Service
         Coverage Ratio of not less than 1.10 to 1 (the "Cap Interest Rate"),
         and require the counterparty to make interest payments on the notional
         principal amount at a rate equal to the amount by which Coupon Rate
         exceeds the Cap Interest Rate;

         (iv) require the counterparty to make such interest payments to an
         account pledged to the Lender pursuant to the Cap Security Agreement;
         and

         (v) be evidenced, governed and secured on terms and conditions, and
         pursuant to documentation (the "Cap Documents"), in form and content
         reasonably acceptable to Fannie Mae, and with a counterparty (a
         "Counterparty") reasonably approved by Fannie Mae.

         SECTION 16.03. Cap Security Agreement; Delivery of Cap Payments.

                                       44
<PAGE>

         Pursuant to a Cap Security Agreement, the Lender shall be granted an
enforceable, perfected, first priority lien on and security interest in each Cap
and payments due under the Cap (including scheduled and termination payments) in
order to secure the Borrower's obligations to the Lender under this Agreement.
With respect to each Cap, the Cap Security Agreement must be delivered by the
Borrower to the Lender no later than the effective date of the Cap.

         SECTION 16.04. Termination.

         The Borrower shall not terminate, transfer or consent to any transfer
of any existing Cap without the Lender's prior written consent as long as the
Borrower is required to maintain a Cap pursuant to this Agreement; provided,
however, that if, and at such time as, any Variable Facility Commitment
terminates, the Borrower shall have the right to terminate the existing Cap with
respect to such Variable Facility Commitment.

         SECTION 16.05. Performance Under Cap Documents.

         The Borrower agrees to comply fully with, and to otherwise perform when
due, its obligations under, all applicable Cap Documents and all other
agreements evidencing, governing and/or securing any Cap arrangement
contemplated under this Article 16. The Borrower shall not exercise, without the
Lender's prior written consent, and upon the occurrence and during the
continuance of an Event of Default, shall exercise, at the Lender's direction,
any rights or remedies under any Cap Document, including without limitation the
right of termination.

         SECTION 16.06. Escrow Provisions.

         (a) Monthly Cap Escrow Payment. Until the Borrower obtains a Cap or
Caps that have a term through the entire term of the Variable Facility
Commitment, the Borrower shall, on the first Business Day of each month, deposit
with the Lender the Monthly Cap Escrow Payment. The "Monthly Cap Escrow Payment"
means, with respect to the first 36 months after the purchase of a Cap for less
than the entire remaining term of any portion of the Variable Facility
Commitment, an amount equal to one thirty-sixth (1/36) of 125% of the cost, as
reasonably estimated quarterly by the Lender, to obtain any required Subsequent
Cap plus any amount required to increase the Cap Escrow Fund to the amount then
required to be funded in the Cap Escrow Fund based on the then current cost
estimate.

         In no event shall the Borrower be required to make deposits into the
Cap Escrow Fund if the amount in the Cap Escrow Fund equals or exceeds 125% of
the cost, as then reasonably estimated by the Lender, to obtain any required
Subsequent Cap.

         In lieu of the Monthly Cap Escrow Payment, Borrower may, on the date
any Cap is purchased, deliver to Lender a letter of credit issued by a financial
institution reasonably acceptable to Lender and having terms and conditions
reasonably acceptable to Lender having a face amount equal to 125% of the cost,
as reasonably estimated by Lender, to obtain any required Subsequent Caps.
Lender or Borrower may require, not more often than quarterly, an increase or
decrease, as the case may be, in the face amount of the Letter of Credit to
increase or decrease, as

                                       45
<PAGE>

the case may be, the face amount of the Letter of Credit to 125% of the then
current estimate of the cost to acquire any required Subsequent Cap.

         SECTION 16.07. Cap Escrow Fund.

         The Lender shall deposit the Monthly Cap Escrow Payments in an
interest-bearing account (the "Cap Escrow Fund") which meets the standards for
custodial accounts as required by Lender from time to time. (The Monthly Cap
Escrow Payment and all other funds in the Cap Escrow Fund are referred to
collectively as the "Cap Escrow Fund"). Lender or a designated representative of
Lender shall have the sole right to make withdrawals from such account. All
interest earned on funds in the Cap Escrow Fund shall be added to and become
part of the Cap Escrow Fund. Lender shall not be responsible for any losses
resulting from the investment of the Cap Escrow Fund or for obtaining any
specific level or percentage of earnings on such investment. If applicable law
requires and provided that no Event of Default or Potential Event of Default
exists under any of the Loan Documents, Lender shall pay to Borrower the
interest earned on the Cap Escrow Fund once each year. Borrower assigns to
Lender the Cap Escrow Fund as additional security for all of the Borrower's
obligations under the Loan Documents; provided, however, Lender shall make
disbursements from the Cap Escrow Fund in accordance with the terms of this
Agreement. Funds in the Cap Escrow Fund shall be used by the Lender to purchase
any required Subsequent Cap. To the extent such Cap Escrow Funds are
insufficient to purchase any required Subsequent Cap, the Borrower shall
promptly remit such funds to the Lender or the provider of the Cap. Any amount
in the Cap Escrow Fund not used to purchase a Subsequent Cap shall be returned
to the Borrower at such time as Lender determines that no additional Subsequent
Caps will be required to be purchased.

                                   ARTICLE 17
                            MISCELLANEOUS PROVISIONS

         SECTION 17.01. Counterparts.

         To facilitate execution, this Agreement may be executed in any number
of counterparts. It shall not be necessary that the signatures of, or on behalf
of, each party, or that the signatures of all persons required to bind any
party, appear on each counterpart, but it shall be sufficient that the signature
of, or on behalf of, each party, appear on one or more counterparts. All
counterparts shall collectively constitute a single agreement. It shall not be
necessary in making proof of this Agreement to produce or account for more than
the number of counterparts containing the respective signatures of, or on behalf
of, all of the parties hereto.

         SECTION 17.02. Amendments, Changes and Modifications.

         This Agreement may be amended, changed, modified, altered or terminated
only by written instrument or written instruments signed by all of the parties
hereto.

         SECTION 17.03. Payment of Costs, Fees and Expenses.

<PAGE>

         Borrower shall pay, on demand, all reasonable fees, costs, charges or
expenses (including the fees and expenses of attorneys, accountants and other
experts) incurred by Lender in connection with:

                  (a) Any amendment, consent or waiver to this Agreement or any
of the Loan Documents (whether or not any such amendments, consents or waivers
are entered into).

                  (b) Defending or participating in any litigation arising from
actions by third parties and brought against or involving Lender with respect to
(i) any Mortgaged Property, (ii) any event, act, condition or circumstance in
connection with any Mortgaged Property or (iii) the relationship between Lender
and Borrower, Sun and the OP in connection with this Agreement or any of the
transactions contemplated by this Agreement unless caused by the gross
negligence or willful misconduct of Lender.

                  (c) The administration or enforcement of, or preservation of
rights or remedies under, this Agreement or any other Loan Documents or in
connection with the foreclosure upon, sale of or other disposition of any
Collateral granted pursuant to the Loan Documents.

                  (d) Any disclosure documents, including fees payable to any
rating agencies, including the reasonable fees and expenses of Lender's outside
attorneys and accountants.

Borrower shall also pay, on demand, any transfer taxes, documentary taxes,
assessments or charges made by any governmental authority by reason of the
execution, delivery, filing, recordation, performance or enforcement of any of
the Loan Documents or the Advances. However, Borrower will not be obligated to
pay any franchise, excise, estate, inheritance, income, excess profits or
similar tax on Lender. Any attorneys' fees and expenses payable by Borrower
pursuant to this Section shall be recoverable separately from and in addition to
any other amount included in such judgment, and such obligation is intended to
be severable from the other provisions of this Agreement and to survive and not
be merged into any such judgment. Any amounts payable by Borrower pursuant to
this Section, with interest thereon if not paid when due, shall become
additional indebtedness of Borrower secured by the Loan Documents. Such amounts
shall bear interest from the date such amounts are due until paid in full at the
weighted average, as determined by Lender, of the interest rates in effect from
time to time for each Advance unless collection from Borrower of interest at
such rate would be contrary to applicable law, in which event such amounts shall
bear interest at the highest rate which may be collected from Borrower under
applicable law. The provisions of this Section are cumulative with, and do not
exclude the application and benefit to Lender of, any provision of any other
Loan Document relating to any of the matters covered by this Section.

         SECTION 17.04. Payment Procedure.

         All payments to be made to Lender pursuant to this Agreement or any of
the Loan Documents shall be made in lawful currency of the United States of
America and in immediately available funds by wire transfer to an account
designated by Lender before 2:00 p.m. (Washington, D.C. time) on the date when
due.

         SECTION 17.05. Payments on Business Days.

         In any case in which the date of payment to Lender or the expiration of
any time period hereunder occurs on a day which is not a Business Day, then such
payment or expiration of such time period need not occur on such date but may be
made on the next succeeding Business Day with the same force and effect as if
made on the day of maturity or expiration of such period, except that interest
shall continue to accrue for the period after such date to the next Business
Day.

         SECTION 17.06. Choice of Law; Consent to Jurisdiction; Waiver of Jury
Trial.

RELATION TO THE NOTES, THE SECURITY DOCUMENTS OR ANY OTHER LOAN DOCUMENT SHALL
BE, EXCEPT AS OTHERWISE PROVIDED HEREIN, LITIGATED IN DISTRICT OF COLUMBIA. THE
LOCAL AND FEDERAL COURTS AND AUTHORITIES WITH JURISDICTION IN DISTRICT OF

INCLUDING THOSE CONTROVERSIES RELATING TO THE EXECUTION, JURISDICTION, BREACH,
ENFORCEMENT OR COMPLIANCE WITH THE NOTES, THE SECURITY DOCUMENTS OR ANY OTHER
ISSUE ARISING UNDER, RELATING TO, OR IN CONNECTION WITH ANY OF THE LOAN

RIGHT TO TRIAL BY JURY TO THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER
EXIST. THIS WAIVER IS INTENDED TO ENCOMPASS INDIVIDUALLY EACH INSTANCE AND EACH
ISSUE AS TO WHICH THE RIGHT TO A JURY TRIAL WOULD OTHERWISE ACCRUE. FURTHER, THE
BORROWER AND SUN HEREBY CERTIFY THAT NO REPRESENTATIVE OR AGENT OF LENDER
(INCLUDING, BUT NOT LIMITED TO, LENDER'S COUNSEL) HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, TO THE BORROWER AND SUN THAT LENDER WILL NOT SEEK TO ENFORCE THE
PROVISIONS OF THIS SECTION. THE FOREGOING PROVISIONS WERE KNOWINGLY, WILLINGLY
AND VOLUNTARILY AGREED TO BY BORROWER AND SUN UPON CONSULTATION WITH INDEPENDENT
LEGAL COUNSEL SELECTED BY BORROWER'S AND SUN'S FREE WILL.

         SECTION 17.07. Severability.

Document shall be held invalid, illegal or unenforceable in any jurisdiction,

                    SECOND AMENDMENT TO AMENDED AND RESTATED
                           SUBORDINATED LOAN AGREEMENT

         THIS SECOND AMENDMENT TO AMENDED AND RESTATED SUBORDINATED LOAN
AGREEMENT (the "Amendment") is made and entered into as of June 18, 2002 by and
between ORIGEN FINANCIAL L.L.C., a Delaware limited liability company (the

Michigan 48009, and SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP, a Michigan

capitalized terms not defined in this Amendment shall have the meanings given to
them in the Loan Agreement.

         B. Origen Inc. was merged with and into Borrower effective April 25,

         NOW, THEREFORE, the parties agree as follows:

and replaced with the following Section 1:

         "Loan. The Line of Credit provided hereunder shall have the following
terms:

         Type of Loan: Line of Credit

         Note Amount: $23,125,000

         Maturity: December 18, 2002

         Aggregate Fees: $187,500

         The Loan and any amendments, extensions, renewals, or refinancing
         thereof are subject to this Agreement."

         2. Upon the execution of this Amendment, Borrower shall execute and
deliver to Lender a Fourth Amended and Restated Promissory Note dated June 18,
2002, in the form attached to this Amendment as Exhibit A (the "Fourth Amended
Note"). The Fourth Amended Note shall replace the Third Amended and Restated
Promissory Note dated March 22, 2002 executed by Borrower and Origen Inc. in
connection with the Loan Agreement. All references in the Loan Agreement to the
