1.       BASIS OF PRESENTATION AND FORMATION OF COMPANY:

         The accompanying unaudited condensed consolidated financial statements
         of Chateau Communities, Inc. (the "Company"), a real estate investment
         trust (REIT), have been prepared in accordance with generally accepted
         accounting principles for interim financial information and with the
         instructions to Form 10-Q and Rule 10-01 of Regulation S-X.
         Accordingly, they do not include all of the information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. In the opinion of management, all adjustments
         considered necessary for a fair presentation have been included, and
         such adjustments are of a normal recurring nature. The year-end
         condensed consolidated balance sheet was derived from audited
         consolidated financial statements, but does not include all disclosures
         required by generally accepted accounting principles. For further
         information, refer to the consolidated financial statements and
         footnotes thereto included in the Company's annual report on Form 10-K
         for the year ended December 31, 1997.

         On February 11, 1997, the Company completed a strategic merger of
         equals (the "Merger") with ROC Communities, Inc. ("ROC"). The Merger
         and related transactions were accounted for using the purchase method
         of accounting in accordance with generally accepted accounting
         principles. Accordingly, the assets and liabilities of ROC were
         adjusted to fair value for financial accounting purposes and the
         results of operations of ROC were included in the results of operations
         of the Company beginning in February 1997.

         equity of an enterprise that result from recognized transactions and
         other economic events of the period other than transactions with owners
         in their capacity as owners. Besides net income, other comprehensive
         income includes foreign currency items, minimum pension liability
         adjustments, and unrealized gains and losses on certain investments in

6.       SUBSEQUENT EVENTS:

         In April 1998, the Company completed the acquisition of 11 manufactured
         home communities, in Michigan (9) and North Carolina (2), containing
         approximately 3,000 homesites, for an aggregate purchase price of
         approximately $76 million. These acquisitions were financed by $45
         million in borrowings under the Company's line of credit, the issuance
         of 551,251 OP Units and the assumption of mortgage debt of $12.5
         million with an average interest rate of 7.9 percent. The OP Units were
         issued in private transactions exempt from the registration
         requirements of the Securities Act of 1933, pursuant to section 4(2)
         and or Regulation D thereunder.

         On April 20, 1998, the Company through its operating partnership, CP
         Limited Partnership, completed the issuance of $75 million of 8.125%
         Series A Cumulative Redeemable Preferred Units (the "Series A Preferred
         Units"). The proceeds of which were used to pay off the outstanding
         balances on the Company's line of credit, which were used to finance
         the acquisition of the properties in April and to pay off the $25
         million term loan. The Series A Preferred Units were issued in a
         private transaction exempt from the registration requirements of the
         Securities Act of 1933 by virtue of Section 4(2) thereunder.

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

The following discussion should be read in conjunction with the Condensed
Consolidated Financial Statements and Notes thereto included elsewhere in this
report. Certain statements in this discussion constitute "forward-looking
statements" within the meaning of Section 21E of the Securities Exchange Act of
1934, as amended. Such forward-looking statements involve known and unknown
risks, uncertainties and other factors which may cause the actual results,
performance or achievements of the Company or industry to be materially
different from any future results, performance or achievements expressed or
implied by such forward-looking statements.

On February 11, 1997, the Company completed a strategic merger of equals (the
"Merger") with ROC Communities, Inc. ("ROC"). The Merger and related
transactions were accounted for using the purchase method of accounting in
accordance with generally accepted accounting principles. Accordingly, the
assets and liabilities of ROC were adjusted to fair value for financial
accounting purposes and the results of operations of ROC were included in the
results of operations of the Company beginning in February 1997.

RESULTS OF OPERATIONS

Comparison of three months ended March 31, 1998 to three months ended March 31,
1997

For the three months ended March 31, 1998, income before minority interest was
$7,369,000, an increase of $1,781,000 from the three months ended March 31,
1997. The increase was due primarily to the Merger and increased net operating
income from communities owned by the Company or ROC at the beginning of the 1997
period (Core 1997 Portfolio). 

Rental revenue for the three months ended March 31, 1998 was $39,093,000; an
increase of $10,185,000 from the three months ended March 31, 1997. The majority
of the increase was due to the Merger and the acquisitions in 1997 and the first
quarter of 1998. The remaining increase was due to rent increases and occupancy
gains in the Company's Core 1997 Portfolio.

Weighted average occupancy for the three months ended March 31, 1998 was 42,684
sites compared with 32,809 sites for the same period in 1997. The occupancy rate
was 92 percent on approximately 47,700 sites as of March 31, 1998, compared to
92.3 percent on approximately 43,000 sites as of March 31, 1997. The decrease in
the occupancy rate is primarily due to the increase in available sites added
through expansions of existing communities and acquisitions of properties with
lower occupancy rates that are in some phase of development. The occupancy rate
on the stabilized portfolio was 93.5 percent as of March 31, 1998. On a per site
basis, weighted average monthly rental revenue for the three months ended March
31, 1998 was $293 compared with $285 in the same period of 1997. For the
Company's Core 1997 Portfolio, on a per site basis, weighted average monthly
rental revenue for the three months ended March 31, 1998 was $296 compared with
$281 for the same period in 1997, an increase of 5.3 percent.

Management fee, interest and other income primarily includes management fee
income for the management of 33 manufactured home communities, equity earnings
from the Company's sales subsidiary and interest income on notes receivable and
advances to joint ventures/affiliates.

Property operating and maintenance expense for the three months ended March 31,
1998 increased by $3,068,000 or 38.4 percent from the same period a year ago.
The majority of the increase was due to the Merger and the 1997 and 1998
acquisitions. The remaining increase is due to increases in the Company's Core
1997 Portfolio. On a per site basis, monthly weighted average property operating
and maintenance expense increased 6.3 percent from $81 for the three months
ended March 31, 1997 to $87 for the same period in 1998. A portion of this
increase is due to the operating expenses related to the properties managed by
the Company for a management fee beginning in February 1997.



                                       8
<PAGE>   11

Real estate taxes for the three months ended March 31, 1998, increased by
$826,000 or 38.8 percent from the three months ended March 31, 1997. The
increase is due primarily to the Merger and acquisitions and expansions of
communities and general increases. On a per site basis, monthly weighted real
estate taxes were $23.08 for the three months ended 1998 compared to $21.63 for
the same period in 1997. Real estate taxes may increase or decrease due to
inflation, expansions and improvements of communities, as well as changes in
taxation in the tax jurisdictions in which the Company operates.

Administrative expense for the three months ended March 31, 1998 increased due
to the Merger and the Company's increased size. Administrative expense in 1998
was 5.35 percent of revenues as compared to 5.26 percent in 1997.

Interest and related amortization costs increased for the three months ended
March 31, 1998 by $2,118,000, as compared with the three months ended March 31,
1997. The increase is attributable to the indebtedness incurred to finance the
1997 and 1998 acquisitions. Interest expense as a percentage of average debt
outstanding decreased to approximately 7.48 percent in 1998 from approximately
7.57 percent in 1997. The decrease is due primarily to the issuance of $100
million of the Mandatory Par Put Remarketing Securities in December 1997 at an
effective rate of 6.44 percent and a lower borrowing rate of 110 basis points
over LIBOR on the Company's line of credit.

Depreciation expense for the three months ended March 31, 1998 increased $2.4
million from the same period a year ago. The increase is directly attributable
to the Merger and acquisitions. Depreciation expense as a percentage of average
depreciable rental property in 1998 remained relatively unchanged from 1997.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $19,021,000 for the three months
ended March 31, 1998, compared to $9,481,000 for the three months ended March
31, 1997. The increase in cash provided by operating activities was due
primarily to the increase in net operating income.

Net cash provided by financing activities for the three months ended March 31,
1998 was $41,307,000. This was due primarily to the proceeds received from the
issuance of common stock of approximately $53.9 million, offset partially by
$12.1 million in dividends and distributions paid to shareholders and OP
Unitholders in the first quarter of 1998.

Net cash used in investing activities for the three months ended March 31, 1998
was $74,797,000. This amount represented acquisitions, joint venture
investments, capital expenditures and construction and development costs. In the
first quarter of 1998, the Company acquired, through three separate portfolio
acquisitions, 19 manufactured home communities and three park model/RV
communities with a total of 3,854 homesites and 1,359 park model/RV sites. Nine
of the properties acquired, containing approximately 900 homesites and 1,100
park model/RV sites, are subject to long term ground leases. The Company's total
investment of $93.9 million was financed primarily by the assumption of $23.1
million of mortgage and other notes, the issuance of 370,000 OP Units, borrowing
under the Company's line of credit and proceeds from the issuance of 1.85
million common shares in February 1998. The proceeds of $53.9 million were used
for the above transactions and to repay the Company's line of credit. For the
three months ended March 31, 1998, construction and development costs, including
joint venture investments were approximately $12.5 million, while recurring
property capital expenditures, other than construction and development costs,
were approximately $800,000. Capital expenditures have historically been
financed with funds from operations and it is the Company's intention that such
future expenditures will be financed with funds from operations.

The Company has available two credit facilities with the First National Bank of
Chicago and other lenders, consisting of a $25 million term loan and a $75
million revolving line of credit (the "First Chicago Credit Facilities"). The
interest rate on the revolving credit facility was reduced to LIBOR plus 110
basis points (from LIBOR plus 150 basis points). In addition, the Company
secured a $7.5 million revolving line of credit from Colorado National Bank
which bears interest at a rate of LIBOR plus 125 basis points (the "CNB
Facility" and, together with the First Chicago Credit Facilities, the "Credit
Facilities"). As of March 31, 1998, approximately $25 million was outstanding
under the Credit Facilities and the Company had available $82.5 million in
additional borrowing capacity.



                                       9

In December 1997, the Company issued 6.92% Mandatory Par Put Remarketed
Securities(SM) ("MOPPRS(SM)") due December 10, 2014. The net proceeds to the
Company from the issuance before deducting offering expenses, were approximately
$102.0 million. The net proceeds from the MOPPRS(SM) were utilized primarily to
reduce outstanding balances under the Credit Facilities and to finance
acquisitions. The MOPPRS(SM) are rated as "BBB" by Standard & Poor's Rating
Service and "Baa3" by Moody's Investors Service.

In connection with the issuance of the MOPPRS(SM), the Company and the Operating
Partnership entered into a Remarketing Agreement, dated as of December 23, 1997
(the "Remarketing Agreement"), with the remarketing dealer named therein (the
"Remarketing Dealer"), pursuant to which the MOPPRS(SM) are subject to mandatory
tender in favor of the Remarketing Dealer on December 10, 2004 (the "Remarketing
Date"), for a purchase price equal to 100% of the principal amount of the
outstanding MOPPRS(SM). Upon the Remarketing Dealer's election to remarket the
MOPPRS(SM), the interest rate to the December 10, 2014 maturity date of the
MOPPRS(SM) will be adjusted to equal the sum of 5.75% plus the Applicable Spread
(as defined in the Remarketing Agreement). In the event the Remarketing Dealer
does not elect to remarket the MOPPRS(SM), the MOPPRS(SM) will mature on the
Remarketing Date.

As of March 31, 1998, the Company had outstanding, in addition to the Credit
Facilities and the MOPPRS(SM), $145 million of other unsecured senior debt with
a weighted average interest rate and maturity of 8.2 percent and 3.75 years,
respectively, and $120 million of secured mortgage debt with a weighted average
interest rate and maturity of 7.86 percent and 2.5 years, respectively.

Repayment of long-term borrowings and amounts outstanding under the Credit
Facilities, future acquisitions of communities and land for development and new
community development activities represent the principal long-term liquidity
needs of the Company. The Company does not expect to generate sufficient funds
from operations to finance these long-term liquidity needs and instead intends
to meet its long-term liquidity requirements through additional borrowing under
the Credit Facilities or other lines of credit, the issuance of additional
equity or debt securities and the assumption of existing secured or unsecured
indebtedness.

The Company expects to meet its short-term liquidity requirements, including
expansion activities and capital expenditure requirements, through cash flow
from operations and, if necessary, borrowings under the Credit Facilities and
other lines of credit.

In April 1998, the Company completed the acquisition of 11 manufactured home
communities, in Michigan and North Carolina, containing approximately 3,000
homesites, for an aggregate purchase price of approximately $76 million. These
acquisitions were financed by $45 million in borrowings under the Company's
Credit Facilities, the issuance of 551,251 OP Units and the assumption of
mortgage debt of $12.5 million with an average interest rate of 7.9 percent.

On April 20, 1998, the Company through its operating partnership, CP Limited
Partnership, completed the issuance of $75 million of 8.125% Series A Cumulative
Redeemable Preferred Units (the "Series A Preferred Units"). The proceeds of
this issuance were used to pay off the outstanding balances on the Company's
Credit Facilities, which were used to finance the acquisition of the properties
in April and to pay off the $25 million term loan portion of the Credit
Facilities.

Effective January 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130 (SFAS 130), Reporting Comprehensive Income. SFAS 130 is
designed to report a measure of all changes in equity of an enterprise that
result from recognized transactions and other economic events of the period
other than transactions with owners in their capacity as owners. Besides net
income, other comprehensive income includes foreign currency items, minimum
pension liability adjustments, and unrealized gains and losses on certain
investments in debt and equity securities. The Company has no items of other
comprehensive income in any period presented in the accompanying interim
financial statements.

OTHER

Funds from operations (FFO) is defined by the National Association of Real
Estate Investment Trusts (NAREIT) as net income excluding gains (or losses) from
debt restructuring and sales of property plus rental property depreciation and
amortization. Management believes that FFO is an important and widely used
measure of the operating performance of REITs which provides a relevant basis
for comparison among REITs. FFO (i) does not represent cash flow from operations
as defined by generally accepted accounting principles; (ii) should not be
considered as an alternative to net income as a measure of operating performance
or to cash flows from operating, investing and financing activities; and (iii)
is not an alternative to cash flows as a measure of liquidity. FFO is calculated
as follows:
