SEGMENT REPORTING (AMOUNTS IN THOUSANDS): The consolidated operations of the Company can be segmented into manufactured home sales and property operations segments.

NOI is derived from revenues (determined in accordance with GAAP) minus property operating expenses and real estate taxes (determined in accordance with GAAP). NOI does not represent cash generated from operating activities in accordance with GAAP and should not be considered to be an alternative to net income (determined in accordance with GAAP) as an indication of the Company's financial performance or to be an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company's liquidity; nor is it indicative of funds available for the Company's cash needs, including its ability to make cash distributions. The Company believes that net income is the most directly comparable GAAP measurement to net operating income. Net income includes interest and depreciation and amortization which often have no effect on the market value of a property and therefore limit its use as a performance measure. In addition, such expenses are often incurred at a parent company level and therefore are not necessarily linked to the performance of a real estate asset. The Company believes that net operating income is helpful to investors as a measure of operating performance because it is an indicator of the return on property investment, and provides a method of comparing property performance over time. The Company uses NOI as a key management tool when evaluating performance and growth of particular properties and/or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization and non-property specific expenses such as general and administrative expenses, all of which are significant costs, and therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall. (2) Seasonal recreational vehicle revenue is included in Property Operations revenues and is approximately $4.0 million annually. This seasonal revenue is recognized approximately 70% in the first quarter, 5% in both the second and third quarters and 20% in the fourth quarter of each fiscal year. 10

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (IN THOUSANDS): 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 portion of 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. The changes in the value of these hedges are reflected in other comprehensive income/loss on the balance sheet. 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 months ended March 31, 2005 and 2004 totals negative $0.4 million and positive $0.4 million, respectively. SFAS No. 133, the "Accounting for Derivative Instruments and Hedging Activities," requires all derivative instruments to be carried at fair value on the balance sheet. The fair value of the instruments approximates a liability of $0.2 million and $1.1 million as of March 31, 2005 and December 31, 2004, respectively. These valuation adjustments will only be realized if the Company terminates the swaps prior to maturity. This is not the intent of the Company and, therefore, the net of valuation adjustments through the various maturity dates will approximate zero. 11

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 9. STOCK OPTIONS (IN THOUSANDS): 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, 2005 and 2004: 2005 2004 ---------- ---------- Net income, as reported $ 687 $ 5,570 Stock-based compensation expense under fair value method (14) (19) ---------- ---------- Pro forma net income $ 673 $ 5,551 ========== ========== Earnings per share (Basic), as reported $ 0.04 $ 0.30 ========== ========== Earnings per share (Basic), pro forma $ 0.04 $ 0.30 ========== ========== Earnings per share (Diluted), as reported $ 0.04 $ 0.30 ========== ========== Earnings per share (Diluted), pro forma $ 0.04 $ 0.29 ========== ========== Stock options issued after April 30, 2004 were valued using the Binomial model rather than the Black-Scholes-Merton formula. The difference in valuation between the two methods was not material. 12

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 11. RECENT ACCOUNTING PRONOUNCEMENTS: In December 2004, the Financial Accounting Standards Board (FASB) issued Share-Based Payment Statement No. 123(R), 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 statement, all forms of share-based payments to employees, including employee stock options, must 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 Statement eliminates the ability to account for share-based compensation transactions using APB Opinion No. 25, Accounting for Stock Issued to Employees for options granted after June 15, 2005. On April 14, 2005, the SEC announced it would permit companies to implement statement 123(R) at the beginning of their next fiscal year. The Company plans to adopt the new rules reflected in statement 123(R) using the modified-prospective method, effective January 1, 2006. The Company is currently evaluating the impact of this standard on its results of operations and financial position. 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 current status is that the proceedings in North Carolina have been stayed pending final determination in Michigan as to whether the dispute should be submitted to arbitration. 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 March 31, 2005, the Company sold one property located in Leesburg, FL consisting of 96 manufactured housing sites for approximately $2.2 million and signed an agreement to sell a community located in Bonita Springs, FL comprised of 167 recreational vehicle sites for approximately $3.1 million. Combined revenues for these properties totaled $0.3 million and $0.7 million for the three month period ended March 31, 2005 and twelve month period ended December 31, 2004, respectively. Net income from these properties was $0.1 million and $0.1 million for the three month period ended March 31, 2005 and twelve month period ended December 31, 2004, respectively. Due to the immaterial effect of these transactions, both qualitatively and quantitatively, the provisions of SFAS 144, Accounting for the Impairment or Disposal of Long-Lived Assets will not be applied. 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 2004 Annual Report filed with the Securities and Exchange Commission on Form 10-K. During the three months ended March 31, 2005, 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, 2005 and 2004 For the three months ended March 31, 2005, income from operations before minority interest decreased by $5.7 million from $7.4 million to $1.7 million, when compared to the three months ended March 31, 2004. The decrease was due to increased expenses of $7.2 million and decreased equity income from affiliate of $0.3 million, offset by increased revenues of $1.8 million as described in more detail below. Income from rental property increased by $2.9 million from $42.9 million to $45.8 million, or 6.8 percent, due primarily to rent increases and other community revenues. Revenues from home sales decreased by $0.2 million from $4.0 million to $3.8 million, or 5.0 percent. The decline in the number of homes sold was offset by increases in average sales prices. Ancillary revenues, net decreased by $0.1 million from $0.6 million to $0.5 million due primarily to increased refurbishment costs of homes utilized in the Company's rental program. Interest income decreased by $0.2 million from $1.8 million to $1.6 million, or 11.1 percent, due primarily to a decrease in interest earning notes and receivables. Other operating income decreased by $0.5 million from $0.3 million to a loss of $0.2 million due primarily to an increase in expenditures on unsuccessful acquisitions. 15

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: Property operating and maintenance expenses increased by $0.8 million from $10.2 million to $11.0 million, or 7.8 percent. The increase was due to increases in utility costs ($0.4 million), payroll expense ($0.1 million), repair and maintenance expense ($0.1 million), and other miscellaneous expenses ($0.2 million). Cost of home sales decreased by $0.7 million from $3.1 million to $2.4 million, or 22.6 percent, due primarily to a decline in the number of homes sold. Real estate taxes increased by $0.6 million from $3.2 million to $3.8 million, or 18.8 percent, due primarily to increases in assessments and tax rates. General and administrative expenses for rental property increased by $0.7 million from $2.8 million to $3.5 million, or 25.0 percent, due to an increase in payroll and benefits ($0.3 million), legal costs ($0.3 million), and other miscellaneous expenses ($0.1 million). Depreciation and amortization increased by $1.8 million from $11.2 million to $ 13.0 million, or 16.1 percent, due primarily to change in estimated useful lives of homes utilized in the Company's rental program. Interest expense increased by $4.4 million from $10.3 million to $14.7 million, or 42.7 percent, primarily due to increased debt levels somewhat offset by lower interest rates. While all costs have yet to be incurred, the settlement of the Company's insurance claim relating to the Florida hurricanes of 2004 justifies a reduction of $0.5 million in the Company's reserve for loss. 16

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS SAME PROPERTY INFORMATION The following table reflects property-level financial information as of and for the three months ended March 31, 2005 and 2004. The "Same Property" data represents information regarding the operation of communities owned as of January 1, 2004 and March 31, 2005. 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.

NOI is derived from revenues (determined in accordance with GAAP) minus property operating expenses and real estate taxes (determined in accordance with GAAP). NOI does not represent cash generated from operating activities in accordance with GAAP and should not be considered to be an alternative to net income (determined in accordance with GAAP) as an indication of the Company's financial performance or to be an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company's liquidity; nor is it indicative of funds available for the Company's cash needs, including its ability to make cash distributions. The Company believes that net income is the most directly comparable GAAP measurement to net operating income. Net income includes interest and depreciation and amortization which often have no effect on the market value of a property and therefore limit its use as a performance measure. In addition, such expenses are often incurred at a parent company level and therefore are not necessarily linked to the performance of a real estate asset. The Company believes that net operating income is helpful to investors as a measure of operating performance because it is an indicator of the return on property investment, and provides a method of comparing property performance over time. The Company uses NOI as a key management tool when evaluating performance and growth of particular properties and/or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization and non-property specific expenses such as general and administrative expenses, all of which are significant costs, and therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall. (2) Occupancy % and weighted average rent relates to manufactured housing sites, excluding recreational vehicle sites. 17

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS SAME PROPERTY INFORMATION, CONTINUED On a same property basis, property net operating income increased by $0.4 million from $29.0 million to $29.4 million, or 1.3 percent. Income from rental property increased by $0.5 million from $40.2 million to $40.7 million, or 1.2 percent, due primarily to increases in rents including water and property tax pass through. Property operating expenses increased by $0.1 million from $11.2 million to $11.3 million, or 1.0 percent, due primarily to increases in real estate taxes and utility expenses. 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, the purchase of new and pre-owned homes and debt repayment. The Company expects to meet its short-term liquidity requirements through its working capital provided by operating activities and through its $115.0 million line of credit. The Company considers these resources 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 $2 to $5 million in developments consisting of expansions to existing communities and the development of new communities during 2005. 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 invest substantial amounts in the acquisition of properties during 2005, depending upon a number of factors, including the availability of high-quality properties that meet the Company's criteria for acquisition. The Company will finance these investments using the proceeds from its secured financing transactions, the temporary use of its line of credit until permanent secured financing can be arranged and through the assumption of existing debt on the properties. The Company has also invested approximately $15 million in the acquisition of homes primarily intended for its rental program. Expenditures for the reminder of 2005 will be dependent upon the condition of the markets for repossessions and new home sales as well as rental homes. Cash and cash equivalents decreased by $39.8 million to $12.8 million at March 31, 2005 compared to $52.6 million at December 31, 2004. Net cash provided by operating activities increased by $3.7 million to $22.8 million for the three months ended March 31, 2005 compared to $19.1 million for the three months ended March 31, 2004. 18

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS LIQUIDITY AND CAPITAL RESOURCES CONTINUED: 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, 2004. 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 shares of its capital stock, issue equity units in the Operating Partnership or sell selected assets. 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, 2004. If the Company is unable obtain additional debt or equity financing on acceptable terms, the Company's business, results of operations and financial condition will be adversely impacted. At March 31, 2005, the Company's debt to total market capitalization approximated 59.1 percent (assuming conversion of all Common OP Units to shares of common stock). The debt has a weighted average maturity of approximately 8.3 years and a weighted average interest rate of 5.1 percent. Capital expenditures for the three months ended March 31, 2005 and 2004 included recurring capital expenditures of $1.4 million and $1.1 million, respectively. Net cash provided by investing activities increased by $7.0 million to $9.1 million for the three months ended March 31, 2005 compared to $2.1 million provided by investing activities for the three months ended March 31, 2004. This increase was due to a $40.0 million increase in net proceeds from sale of short-term investments and a $2.2 million decrease in notes receivable and officers' notes, net, offset by increased investment in rental properties of $22.4 million, reduction in distributions from affiliate of $0.5 million, and a $12.3 million decrease in proceeds from sales of installments loans to Origen. Net cash used in financing activities increased by $52.0 million to $71.7 million for the three months ended March 31, 2005 from $19.7 million for the three months ended March 31, 2004. This increase was primarily due to payments to retire Perpetual Preferred Operating Partnership Units of $50.0 million, purchases of Company stock of $2.4 million under a one million share buy back authorization, and a $3.4 million decrease of proceeds from issuance of common stock, offset by a $2.7 million decrease in repayments of notes payable and other debt, inclusive of repayments on line of credit, a $0.6 million decrease in distributions, and a $0.5 million increase in payments for deferred financing costs. 19

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS SUPPLEMENTAL MEASURE: Funds from operations ("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 depreciable operating property, plus real estate-related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of the Company's operating performance. Management generally considers FFO to be a useful measure for reviewing comparative operating and financial performance because, by excluding gains and losses related to sales of previously depreciated operating real estate assets and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not readily apparent from net income. Management believes that the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Because FFO excludes significant economic components of net income including depreciation and amortization, FFO should be used as an adjunct to net income and not as an alternative to net income. The principal limitation of FFO is that it does not represent cash flow from operations as defined by GAAP 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. FFO only provides investors with an additional performance measure. Other REITS may use different methods for calculating FFO and, accordingly, the Company's FFO may not be comparable to other REITs. The following table reconciles net income to FFO and calculates both basic and diluted FFO per share for the three months ended March 31, 2005 and 2004 (in thousands): 20

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS SUPPLEMENTAL MEASURE, CONTINUED: RECONCILIATION OF NET INCOME TO FUNDS FROM OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2005 AND 2004 (AMOUNTS IN THOUSANDS EXCEPT FOR PER SHARE DATA) (UNAUDITED) 2005 2004 ------- --------- Net income $ 687 $ 5,570 Adjustments: Depreciation and amortization 13,711 10,841 Valuation adjustment(1) 359 (407) Allocation of SunChamp losses(2) - 300 Income allocated to common minority interests 95 709 ------- -------- Funds from operations (FFO) $14,852 $ 17,013 ======= ======== Weighted average common shares/OP Units outstanding: Basic 20,319 21,175 ======= ======== Diluted 20,421 21,337 ======= ======== FFO per weighted average Common Share/OP Unit - Basic 0.73 0.80 ======= ======== FFO per weighted average Common Share/OP Unit - Diluted 0.73 0.80 ======= ======== (1) 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 the Company has no expectation of terminating the transactions prior to maturity, the net of these noncash valuation adjustments will be zero at the various maturities. As any imperfection related to hedging correlation in these swaps is reflected currently in cash as interest, the valuation adjustments reflect volatility that would distort the comparative measurement of FFO and on a net basis approximate zero. Accordingly, the valuation adjustments are excluded from FFO. The valuation adjustment is included in interest expense. (2) 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 (based on SunChamp as a stand-alone entity) 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 from SunChamp as a stand-alone entity under generally accepted accounting principles are effectively reallocated to the note for purposes of calculating FFO. A situation such as this is not contemplated in the NAREIT definition of FFO due to the unique circumstances of the transaction. Although not comparable to the precise NAREIT definition, the Company believes the inclusion of this item in its calculation of FFO to be appropriate as noted above. 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 $104.7 million and $197.1 million as of March 31, 2005 and 2004, respectively, which bears interest at various Prime and LIBOR/DMBS rates. If Prime or LIBOR/DMBS increased or decreased by 1.00 percent during the three months ended March 31, 2005 and 2004, the Company believes its interest expense would have increased or decreased by approximately $1.1 million and $2.0 million based on the $107.2 million and $204.9 million average balance outstanding under the Company's variable rate debt facilities for the three months ended March 31, 2005 and 2004, respectively. Additionally, the Company had $14.7 million and $32.4 million LIBOR based variable rate mortgage and other notes receivables as of March 31, 2005 and 2004, respectively. If LIBOR increased or decreased by 1.0 percent during the three months ended March 31, 2005 and 2004, the Company believes interest income would have increased or decreased by approximately $0.2 million and $0.3 million based on the $14.7 million and $32.3 million average balance outstanding on all variable rate notes receivable for the three months ended March 31, 2005 and 2004, 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
