The Company considers NOI, given its wide use by and relevance to investors and analysts, an appropriate supplemental measure to net income because NOI provides a measure of rental operations and does not factor in depreciation/amortization and non-property specific expenses such as general and administrative expenses. 10

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 8. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: The Company has entered into four derivative contracts consisting of three interest rate swap agreements and an interest rate cap agreement. The Company's primary strategy in entering into derivative contracts is to minimize the variability that changes in interest rates could have on its future cash flows. The Company generally employs derivative instruments that effectively convert a portion of its variable rate debt to fixed rate debt and to cap the maximum interest rate on its variable rate borrowings. The Company does not enter into derivative instruments for speculative purposes. The swap agreements have the effect of fixing interest rates relative to a collateralized term loan due to FNMA. One swap matures in July 2009, with an effective fixed rate of 4.93 percent. A second swap matures in July 2012, with an effective fixed rate of 5.37 percent. The third swap matures in July 2007, with an effective fixed rate of 3.97 percent. The third swap is effective as long as 90-day LIBOR is 7 percent or lower. The three swaps have an aggregate notional amount of $75.0 million. The interest rate cap agreement has a cap rate of 9.49 percent, a notional amount of $152.4 million and a termination date of April 03, 2006. Each of the Company's derivative contracts is based upon 90-day LIBOR. The Company has designated the first two swaps and the interest rate cap as cash flow hedges for accounting purposes. These three hedges were highly effective and had minimal effect on income. The third swap does not qualify as a hedge for accounting purposes and, accordingly, the entire change in valuation, whether positive or negative, is reflected as a component of interest expense. The valuation adjustment for the three month period ended March 31, 2004 totals a positive $0.4 million. In accordance with SFAS No. 133, the "Accounting for Derivative Instruments and Hedging Activities," which requires all derivative instruments to be carried at fair value on the balance sheet, the Company has recorded a liability of $1.9 million and $0.9 million as of March 31, 2004 and December 31, 2003, respectively. These valuation adjustments will only be realized if the Company terminates the swaps prior to maturity. If held to maturity, the valuation adjustments will approximate zero. 11

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 9. STOCK OPTIONS: The Company accounts for its stock options using the intrinsic value method contained in APB Opinion No. 25. "Accounting for Stock Issued to Employees." If the Company had accounted for options using the methods contained in FASB Statement No. 123, "Accounting for Stock-Based Compensation", net income and earnings per share would have been presented as follows for the three months ended March 31, 2004 and 2003: 2004 2003 -------- -------- Net income, as reported $ 5,570 $ 6,343 Stock-based compensation expense under fair value method (19) (121) -------- -------- Pro forma net income $ 5,551 $ 6,222 ======== ======== Earnings per share (Basic), as reported $ 0.30 $ 0.36 ======== ======== Earnings per share (Basic), pro forma $ 0.30 $ 0.35 ======== ======== Earnings per share (Diluted), as reported $ 0.30 $ 0.35 ======== ======== Earnings per share (Diluted), pro forma $ 0.29 $ 0.35 ======== ======== 10.

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 11. RECENT ACCOUNTING PRONOUNCEMENTS: On March 31, 2004, the Financial Accounting Standards Board (FASB) issued a proposed Statement, Share-Based Payment an Amendment of FASB Statements No. 123 and APB No. 95, that addresses the accounting for share-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments. Under the FASB's proposal, all forms of share-based payments to employees, including employee stock options, would be treated the same as other forms of compensation by recognizing the related cost in the income statement. The expense of the award would generally be measured at fair value at the grant date. Current accounting guidance requires that the expense relating to so-called fixed plan employee stock options only be disclosed in the footnotes to the financial statements. The proposed Statement would eliminate the ability to account for share-based compensation transactions using APB Opinion No. 25, Accounting for Stock Issued to Employees. 12. CONTINGENCIES: On April 9, 2003, T.J. Holdings, LLC ("TJ Holdings"), a member of Sun/Forest, LLC ("Sun/Forest") (which, in turn, owns an equity interest in SunChamp LLC), filed a complaint against the Company, SunChamp LLC, certain other affiliates of the Company and two directors of Sun Communities, Inc. in the Superior Court of Guilford County, North Carolina. The complaint alleges that the defendants wrongfully deprived the plaintiff of economic opportunities that they took for themselves in contravention of duties allegedly owed to the plaintiff and purports to claim damages of $13.0 million plus an unspecified amount for punitive damages. The Company believes the complaint and the claims threatened therein have no merit and will defend it vigorously. The Company is involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition. 13. SUBSEQUENT EVENTS: Subsequent to quarter end the Company announced its plan to initiate a tender offer for all of its $350 million of unsecured notes. The tender offer was completed on May 5, 2004 resulting in the Company's purchase of approximately $345 million in unsecured notes. In connection with the tender offer, the Company paid approximately $398 million in satisfaction of the outstanding principal amounts, a premium to par and associated fees. On April 29, 2004, the Company closed on $237 million of additional secured financing with Fannie Mae. This amount is in addition to the existing $152 million of secured debt with Fannie Mae. Approximately $175 million of the additional funding was used to pay amounts associated with the tender offer. Approximately $60 million remains undrawn pending future uses. The term of the additional Fannie Mae funding is nine years bearing interest at a weighted average rate of approximately 4.62%, with an option by the Company to extend the loan for a tenth year at an interest rate of LIBOR plus 240 basis points. The Fannie Mae loan is secured by manufactured housing communities owned by the Operating Partnership or its affiliates. 13

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 13. SUBSEQUENT EVENTS, CONTINUED: In addition, the Company has secured a commitment for a collateralized mortgage backed securities transaction with Bank of America CMBS Capital Markets, totaling up to $500 million (the "CMBS Loan"). The CMBS Loan will be secured by manufactured housing communities owned by the Operating Partnership and its affiliates. The CMBS Loan consists of three traunches: $100 million with a seven-year term, $200 million with a ten-year term and $180 million with a twelve-year term. The CMBS Loan has an average blended interest rate of 4.98%. The Company expects to close on the CMBS loans within the next forty five (45) days. The Company has entered into agreements to effectively fix the interest rates on substantially all of the CMBS Loan. The Company also closed on a $450 million bridge loan from Bank of America, N.A. as interim financing until the CMBS Loan closes. Proceeds from the bridge loan were used to repay the Company's existing credit facility and to retire the unsecured notes as discussed above. Approximately $115 million of the bridge loan facility remains undrawn. The Company plans to use the remaining proceeds of these financing transactions to acquire additional properties, to repurchase the Company's outstanding stock and for general corporate purposes. The Company is currently negotiating a new revolving line of credit. 14

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW The following discussion and analysis of the consolidated financial condition and results of operations should be read in conjunction with the consolidated financial statements and the notes thereto. Capitalized terms are used as defined elsewhere in this Form 10-Q. SIGNIFICANT ACCOUNTING POLICIES The Company had identified significant accounting policies that, as a result of the judgments, uncertainties, uniqueness and complexities of the underlying accounting standards and operations involved, could result in material changes to its financial condition or result of operations under different conditions or using different assumptions. Details regarding the Company's significant accounting policies are described fully in the Company's 2003 Annual Report filed with the Securities and Exchange Commission on Form 10-K. During the three months ended March 31, 2004, there have been no material changes to the Company's significant accounting policies that impacted the Company's financial condition or results of operations. RESULTS OF OPERATIONS Comparison of the three months ended March 31, 2004 and 2003 For the three months ended March 31, 2004, income from continuing operations before minority interest decreased by $0.5 million from $9.0 million to $8.5 million, when compared to the three months ended March 31, 2003. The decrease was due to increased revenues of $1.6 million and increased equity income from affiliates of $0.3 million offset by increased expenses of $2.4 million as described in more detail below. Income from rental property increased by $1.9 million from $41.0 million to $42.9 million, or 4.6 percent, due to rent increases, other community revenues, and an increase in seasonal recreational vehicle revenue during the first quarter of 2004. Interest and other income decreased by $0.3 million from $2.4 million to $2.1 million, or 12.5 percent, due primarily to a decrease in interest earning notes and receivables. The decrease in revenue from home sales and increase in ancillary revenues relate to operations of the manufactured home sales segment which is discussed in detail below. Property operating and maintenance expenses increased by $0.1 million from $10.1 million to $10.2 million, or 1.0 percent, due to increases in utility expenses. 15

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: Real estate taxes increased by $0.3 million from $2.9 million to $3.2 million, or 10.3 percent, due primarily to increases in assessments and tax rates. Selling, general, and administrative expenses increased by $0.4 million from $3.8 million to $4.2 million, due to an increase in compensation expense, including benefits, primarily related to the systems conversion and compliance with the Sarbanes-Oxley Act. Depreciation and amortization increased by $0.7 million from $10.6 million to $11.3 million, or 6.6 percent, due primarily to additional investment in rental property. Interest expense increased by $0.5 million from $8.8 million to $9.3 million, or 5.7 percent, due to increased debt levels somewhat offset by lower interest rates ($0.9 million), a decrease in capitalized interest ($0.2 million), and reduced by a positive valuation adjustment related to a swap to fix interest rates in the current period ($0.6 million). Equity income from affiliates of $0.2 million represents an estimate of the Company's one-third interest in the operations of Origen, Inc. for the three months ended March 31, 2004. The remaining cost of home sales increase of $0.5 million is discussed in detail below. Sun Home Services The following table summarizes certain financial and statistical data for Sun Home Services for the three months ended March 31, 2004 and 2003: Three Months Ended March 31, Increase/ 2004 2003 (Decrease) Percent Change ---------- ------------- ---------- -------------- New home sales revenues $ 2,363 $ 3,480 $ (1,117) -32.1% Cost of sales 1,809 2,306 (497) -21.6% ---------- ------------- ---------- -------------- Gross profit 554 1,174 (620) -52.8% ========== ============= ========== ============== Pre-owned home sales revenues $ 1,611 $ 634 $ 977 154.1% Cost of sales 1,316 337 979 290.5% ---------- ------------- ---------- -------------- Gross profit 295 297 (2) -0.7% ========== ============= ========== ============== Ancillary revenue, net $ 597 $ 441 $ 156 35.4% ========== ============= ========== ============== Home sales volumes: New homes 45 72 (27) -37.5% Pre-owned homes 82 41 41 100.0% 16

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: Sun Home Services The margin on new homes has declined due to consumer demand shifting to pre-owned homes which are available in substantial quantities. This shift in demand was more than offset by the supply of pre-owned homes, thereby reducing margins. The increase in ancillary revenue, net, is primarily due to increased activity in the Company's rental home program. 17

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: SAME PROPERTY INFORMATION The following table reflects property-level financial information as of and for the three months ended March 31, 2004 and 2003. The "Same Property" data represents information regarding the operation of communities owned as of January 1, 2003 and March 31, 2004. Site, occupancy, and rent data for those communities is presented as of the last day of each period presented. The "Total Portfolio" column differs from the "Same Property" column by including financial and statistical information for new development and acquisition communities.

The Company considers NOI, given its wide use by and relevance to investors and analysts, an appropriate supplemental measure to net income because NOI provides a measure of rental operations and does not factor in depreciation/amortization and non-property specific expenses such as general and administrative expenses. (4) Occupancy % and weighted average rent relates to manufactured housing sites, excluding recreational vehicle sites. On a same property basis, property net operating income increased by $1.3 million from $26.8 million to $28.1 million, or 5.0 percent. Income from property increased by $1.5 million from $36.9 million to $38.4 million, or 4.0 percent, due primarily to increases in rents including water and property tax pass through. Property operating expenses increased by $0.1 million from $10.1 million to $10.2 million, or 1.0 percent, due primarily to increases in real estate taxes, repair and maintenance, and payroll. 18

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS LIQUIDITY AND CAPITAL RESOURCES The Company's principal liquidity demands have historically been, and are expected to continue to be, distributions to the Company's stockholders and the unitholders of the Operating Partnership, property acquisitions, development and expansion of properties, capital improvements of properties and debt repayment. The Company expects to meet its short-term liquidity requirements through its working capital provided by operating activities and its line of credit, as described below. The Company considers its ability to generate cash from operations (anticipated to be approximately $60 million annually) to be adequate to meet all operating requirements, including recurring capital improvements, routinely amortizing debt and other normally recurring expenditures of a capital nature, pay dividends to its stockholders to maintain qualification as a REIT in accordance with the Internal Revenue Code and make distributions to the Operating Partnership's unitholders. The Company plans to invest approximately $5 to $10 million in developments consisting of expansions to existing communities and the development of new communities during 2004. The Company expects to finance these investments by using net cash flows provided by operating activities and by drawing upon its line of credit. Furthermore, the Company may acquire approximately $360 million of properties in 2004, depending upon a number of factors. The Company will finance these investments using the proceeds from anticipated secured financing transactions as discussed in further detail below and through the assumption of existing debt on the properties. Cash and cash equivalents increased by $1.5 million to $25.6 million at March 31, 2004 compared to $24.1 million at December 31, 2003. Net cash provided by operating activities increased by $3.4 million to $19.1 million for the three months ended March 31, 2004 compared to $15.7 million for the three months ended March 31, 2003. The increase resulted primarily from increase in accounts payable and other liabilities, offset by decrease in net income and increase in other assets. The Company's net cash flows provided by operating activities may be adversely impacted by, among other things: (a) the market and economic conditions in the Company's current markets generally, and specifically in metropolitan areas of the Company's current markets; (b) lower occupancy and rental rates of the Company's properties (the "Properties"); (c) increased operating costs, including insurance premiums, real estate taxes and utilities, that cannot be passed on to the Company's tenants; and (d) decreased sales of manufactured homes. See "Factors That May Affect Future Results" in the Company's Annual Report on Form 10-K for the year ended December 31, 2003. The Company had a $105.0 million line of credit at March 31, 2004 with an average interest rate of 1.94 percent, $97.0 million outstanding and $8.0 million available to be drawn under the facility. The line of credit facility contained various leverage, debt service coverage, net worth maintenance and other customary 19

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS LIQUIDITY AND CAPITAL RESOURCES CONTINUED: covenants all of which the Company was in compliance with at March 31, 2004. Subsequent to quarter end, the Company repaid the line of credit and replaced it with a bridge loan bearing interest at LIBOR plus 1.0 percent and maturing in May of 2004. The Company intends to negotiate and announce terms of a new revolving line of credit in the coming months. The Company anticipates meeting its long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, and Operating Partnership unit redemptions through the collateralization of a significant portion of its Properties. From time to time, the Company may also issue equity units in the Operating Partnership or sell selected assets. The Company has obtained commitments for secured financing totaling up to $740.0 million. Proceeds from these transactions will be used to retire $350.0 million of unsecured notes, pay the related costs of this debt retirement, repay the Company's existing line of credit, acquire additional properties, repurchase the Company's outstanding equity securities and for general corporate purposes. The ability of the Company to finance its long-term liquidity requirements in such manner will be affected by numerous economic factors affecting the manufactured housing community industry at the time, including the availability and cost of mortgage debt, the financial condition of the Company, the operating history of the Properties, the state of the debt and equity markets, and the general national, regional and local economic conditions. See "Factors That May Affect Future Results" in the Company's Annual Report on Form 10-K for the year ended December 31, 2003. If the Company is unable to close these secured financings or obtain additional debt or equity financing on acceptable terms, the Company's business, results of operations and financial condition will be impacted. At March 31, 2004, the Company's debt to total market capitalization approximated 44.2 percent (assuming conversion of all Common OP Units to shares of common stock). The debt has a weighted average maturity of approximately 5.0 years and a weighted average interest rate of 5.4 percent. Capital expenditures for the three months ended March 31, 2004 and 2003 included recurring capital expenditures of $1.1 million and $1.0 million, respectively. Net cash provided by investing activities increased by $14.2 million to $2.1 million for the three months ended March 31, 2004 compared to $12.1 million used in investing activities for the three months ended March 31, 2003. This increase was due to a $12.3 million sale of notes receivable to Origen, Inc. and a $5.5 million decrease in investment in and advances to an affiliate, offset by a $0.9 million increase in notes receivable and officers' notes, net, and a $2.7 million increase in rental property investment activities. Net cash used in financing activities increased by $16.8 million to $19.7 million for the quarter ended March 31, 2004 from $2.9 million used in financing activities for the three months ended March 31, 2003. This increase was primarily due to a $15.5 million increase in repayments on the line of credit, a $1.1 million increase in repayments on notes payable and other debt, net, a $1.1 million increase in distributions, and a $0.4 million increase in payments for deferred financing costs, offset by a $1.3 million increase of proceeds from issuance of common stock. 20

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS SUPPLEMENTAL MEASURE: Investors in and analysts following the real estate industry utilize funds from operations ("FFO") as a supplemental performance measure. While the Company believes net income (as defined by generally accepted accounting principles) is the most appropriate measure, it considers FFO, given its wide use by and relevance to investors and analysts, an appropriate supplemental measure. FFO is defined by the National Association of Real Estate Investment Trusts ("NAREIT") as net income (computed in accordance with generally accepted accounting principles) excluding gains (or losses) from sales of property, plus rental property depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Industry analysts consider FFO to be an appropriate supplemental measure of the operating performance of an equity REIT primarily because the computation of FFO excludes historical cost depreciation as an expense and thereby facilitates the comparison of REITs which have different cost bases in their assets. Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time, whereas real estate values have instead historically risen or fallen based upon market conditions. FFO does not represent cash flow from operations as defined by generally accepted accounting principles and is a supplemental measure of performance that does not replace net income as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, FFO is not intended as a measure of a REIT's ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. The following table reconciles net income to FFO for the periods ended March 31, 2004 and 2003 (in thousands): 2004 2003 -------- -------- Net income $ 5,570 $ 6,343 Adjustments: Depreciation and amortization 10,841 10,509 Valuation adjustment(6) (407) 214 Allocation of SunChamp losses(7) 300 850 Income allocated to common minority interests 709 910 -------- -------- Funds from operations (FFO) $ 17,013 $ 18,826 ======== ======== Weighted average common shares/OP Units outstanding: Basic 21,175 20,342 ======== ======== Diluted 21,337 20,468 ======== ======== FFO per weighted average Common Share/OP Unit - Basic 0.80 0.93 ======== ======== FFO per weighted average Common Share/OP Unit - Diluted 0.80 0.92 ======== ======== (6) The Company entered into three interest rate swaps and an interest rate cap agreement. The valuation adjustment reflects the theoretical noncash profit and loss were those hedging transactions terminated at the balance sheet date. As any imperfections related to hedging correlation in these swaps is reflected currently in cash as interest, the valuation adjustments are excluded from funds from operations. The valuation adjustment is included in interest expense. (7) The Company acquired the equity interest of another investor in SunChamp in December 2002. Consideration consisted of a long-term note payable at net book value. Although the adjustment for the allocation of the SunChamp losses is not reflected in the accompanying financial statements, management believes that it is appropriate to provide for this adjustment because the Company's payment obligations with respect to the note are subordinate in all respects to the return of the members' equity (including the gross book value of the acquired equity) plus a preferred return. As a result, the losses that are allocated to the Company under generally accepted accounting principles are effectively reallocated to the note for purposes of calculating funds from operations. At March 31, 2004, there is no remaining balance on the SunChamp note. 21

SUN COMMUNITIES, INC. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK The Company's principal market risk exposure is interest rate risk. The Company mitigates this risk by maintaining prudent amounts of leverage, minimizing capital costs and interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures, which include the periodic use of derivatives. The Company's primary strategy in entering into derivative contracts is to minimize the variability that changes in interest rates could have on its future cash flows. The Company generally employs derivative instruments that effectively convert a portion of its variable rate debt to fixed rate debt. The Company does not enter into derivative instruments for speculative purposes. The Company's variable rate debt totals $197.1 million and $303.3 million as of March 31, 2004 and 2003, respectively, which bears interest at various LIBOR/DMBS rates. If LIBOR/DMBS increased or decreased by 1.00 percent during the three months ended March 31, 2004 and 2003, the Company believes its interest expense would have increased or decreased by approximately $2.0 million and $ 3.1 million based on the $204.9 million and $307.5 million average balance outstanding under the Company's variable rate debt facilities for the three months ended March 31, 2004 and 2003, respectively. Additionally, the Company had $32.4 million and $28.1 million LIBOR based variable rate mortgage and other notes receivables as of March, 2004 and 2003, respectively. If LIBOR increased or decreased by 1.0 percent during the three months ended March 31, 2004 and 2003, the Company believes interest income would have increased or decreased by approximately $0.3 million and $0.3 million based on the $32.3 million and $27.8 million average balance outstanding on all variable rate notes receivable for the three months ended March 31, 2004 and 2003, respectively. The Company has entered into three separate interest rate swap agreements and an interest rate cap agreement. One of these swap agreements fixes $25 million of variable rate borrowings at 4.93 percent for the period April 2003 through July 2009, another of these swap agreements fixes $25 million of variable rate borrowings at 5.37 percent for the period April 2003 through July 2012 and the third swap agreement, which is only effective for so long as 90-day LIBOR is 7 percent or less, fixes $25 million of variable rate borrowings at 3.97 percent for the period April 2003 through July 2007. The interest rate cap agreement has a cap rate of 9.49 percent, a notional amount of $152.4 million and a termination date of April 13, 2006. Each of the Company's derivative contracts is based upon 90-day LIBOR. 23
