SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1. BASIS OF PRESENTATION: These unaudited consolidated financial statements of Sun Communities, Inc., a Maryland corporation, (the "Company") and all majority-owned and controlled subsidiaries including Sun Communities Operating Limited Partnership (the "Operating Partnership"), SunChamp LLC ("SunChamp"), and Sun Home Services, Inc. ("SHS"), have been prepared pursuant to the Securities and Exchange Commission ("SEC") rules and regulations and should be read in conjunction with the consolidated financial statements and notes thereto of the Company included in the Annual Report on Form 10-K for the year ended December 31, 2005. The following notes to consolidated financial statements present interim disclosures as required by the SEC. The accompanying consolidated financial statements reflect, in the opinion of management, all adjustments necessary for a fair presentation of the interim financial statements. All such adjustments are of a normal and recurring nature. Certain reclassifications have been made to prior periods' financial statements in order to conform to current period presentation. 2. SHARE-BASED COMPENSATION: In December 2004, the Financial Accounting Standards Board ("FASB") issued Statement No. 123 (revised December 2004), Share-Based Payment ("SFAS 123(R)"). SFAS 123(R) replaces FASB Statement No. 123 ("Statement 123"), Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25 ("APB 25"), Accounting for Stock Issued to Employees. SFAS 123(R) requires compensation costs related to share-based payment transactions be recognized in the financial statements. With limited exceptions, the amount of compensation cost will be measured based on the grant-date fair value of the equity or the liability instruments issued. In addition, liability awards will be remeasured each reporting period. The Company adopted SFAS 123(R) effective January 1, 2006 using the "modified prospective" method permitted by SFAS 123(R) in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of Statement 123 for all awards granted to employees prior to the effective date of SFAS 123(R) that remain unvested on the effective date. Prior to the adoption of SFAS 123(R), forfeitures were recognized as they occurred. Upon adopting SFAS 123(R), an estimate of future forfeitures is incorporated into the determination of compensation cost for restricted stock grants and stock options. The effect of this estimate of future forfeitures is the reversal of previously recorded compensation expense on restricted stock grants that were not vested at January 1, 2006 and are now expected to be forfeited. For the nine months ended September 30, 2006, the cumulative effect of adopting SFAS 123(R) was an increase in loss from operations of $0.05 million, an increase in loss from continuing operations of $0.05 million, a decrease in net loss of $0.2 million and an increase of $0.01 in both basic and diluted earnings per share. Under the provisions of SFAS 123(R), the recognition of aggregate deferred compensation as a component of equity is no longer permitted. Therefore, the amount of deferred compensation that had been in "Unearned compensation" was eliminated against "Additional paid-in capital" in the Company's Consolidated Balance Sheet commencing January 1, 2006. 7

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 2. SHARE-BASED COMPENSATION, CONTINUED; The modified prospective method of SFAS 123(R) does not require prior periods to be restated to reflect the amount of compensation cost that would have been reflected in the financial statements. The effect on net income and earnings per share if the Company had applied the fair value recognition provisions of Statement 123 to stock-based compensation for the three and nine month periods ended September 30, 2005 was as follows (amounts in thousands except for per share data): THREE MONTHS NINE MONTHS ------------ ----------- Net loss, as reported $(3,725) $(3,788) Stock based compensation expense included in net income as reported $ 447 $ 1,518 Stock-based compensation expense under fair value method (461) (1,561) ------- ------- Pro forma net loss $(3,739) $(3,831) ======= ======= Earnings (loss) per share (Basic and Diluted), as reported $ (0.21) $ (0.21) ======= ======= Earnings (loss) per share (Basic and Diluted), pro forma $ (0.21) $ (0.22) ======= ======= Total compensation cost recorded for share-based compensation was $0.5 million and $0.4 million for the three months ended September 30, 2006 and 2005, respectively. Total compensation cost recorded for share-based compensation for the nine months ended September 30, 2006 and 2005 was $2.8 million and $1.5 million, respectively. Included in the compensation cost for the nine months ended September 30, 2006 was $0.04 million related to stock options that were granted prior to the adoption of SFAS 123(R), which are being recognized over the remaining vesting period. The Company awards restricted stock and options to its employees under its Second Amended and Restated Stock Option Plan (the "Plan"). The Plan provides for the issuance of options, stock appreciation rights, restricted stock and other stock based awards. No further awards may be granted under the Plan at this time. The Company believes that the awards better align the interests of its employees with those of its shareholders and has provided these incentives to attract and retain executive officers and key employees. RESTRICTED STOCK The Company's primary share-based compensation is restricted stock. The following table summarizes the Company's restricted stock activity for the nine months ended September 30, 2006: WEIGHTED NUMBER AVERAGE GRANT OF SHARES DATE FAIR VALUE --------- --------------- Nonvested restricted shares at January 1, 2006 417,275 $34.91 Granted -- Vested (65,657) $34.44 Forfeited -- ------- Nonvested restricted shares at September 30, 2006 351,618 $35.00 ======= 8

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 2. SHARE-BASED COMPENSATION, CONTINUED; The remaining compensation expense to be recognized associated with the 351,618 restricted shares outstanding at September 30, 2006 is approximately $7.2 million. That expense is expected to be recognized $0.3 million in the remainder of 2006, $1.7 million in 2007, $1.3 million in 2008, $2.3 million in 2009 and $1.6 million thereafter. For the nine months ended September 30, 2006, the Company recognized $1.8 million of compensation expense related to its outstanding restricted stock. Recipients receive dividend payments on the shares of restricted stock. The total fair value of shares vested during the nine months ended September 30, 2006 and 2005 was $2.3 million and $1.7 million, respectively. PERFORMANCE-BASED RESTRICTED STOCK The Company has 93,750 performance-based restricted shares with aggregate fair value of $3.3 million which may vest on March 1, 2010. The number of shares that will vest will be determined based on the compounded annual growth rate of the Company's per share funds from operations ("FFO") as determined by comparing the per share FFO for the year ended December 31, 2009 with the per share FFO for the year ended December 31, 2005. The Company must achieve compounded annual growth of at least 5% in order for the recipients to receive any amount of the award and at least 9% to receive the entire share award. The Company recognizes expense related to performance-based restricted shares based on an estimate of the number of restricted shares that will ultimately vest. For the nine months ended September 30, 2006, compensation expense of $0.5 million was recognized for the performance-based restricted shares based on an estimated vesting of 46.67% of the shares on March 1, 2010. OPTIONS At September 30, 2006, the Company had 506,155 options outstanding and exercisable under the Plan. For the nine months ended September 30, 2006, the Company recognized $0.03 million of compensation expense related to its outstanding options. No awards were granted in 2006 or 2005. The Black-Scholes option pricing model was used to value options until 2004 at which time the Company changed to the use of the Binomial option pricing model. The Company issues new shares at the time of share option exercise (or share unit conversion). The following table summarizes the Company's option activity for the first nine months of 2006: NUMBER WEIGHTED AVERAGE WEIGHTED AVERAGE AGGREGATE OF EXERCISE PRICE CONTRACTUAL TERM INTRINSIC VALUE SHARES (PER COMMON SHARE) (IN YEARS) (IN 000'S) -------- ------------------ ---------------- --------------- Options outstanding at January 1, 2006 614,839 $29.73 Granted -- Exercised (102,581) $28.35 Forfeited (6,103) $33.50 -------- Options outstanding at September 30, 2006 506,155 $29.96 2.2 $1,288 ======== Options vested and exercisable at September 30, 2006 506,155 $29.96 2.2 $1,288 ======== 9

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 2. SHARE BASED COMPENSATION, CONTINUED; The aggregate intrinsic value of options exercised during the nine months ended September 30, 2006 was $0.2 million. For options exercised during the first nine months of 2005, the aggregate intrinsic value was $0.02 million. PHANTOM AWARDS At September 30, 2006, the Company had 22,500 unvested phantom liability awards with an aggregate fair value of $0.7 million. The phantom awards pay cash bonuses per share equal to the amount of dividend paid per share of common stock. The awards vest (cash bonus is paid) in varying amounts until 2014. The remaining unrecognized expense related to these phantom liability awards is $0.6 million. For the nine months ended September 30, 2006, the Company recognized $0.1 million of compensation expense related to these phantom awards. Awards of 13,000 shares were granted and no shares were vested, exercised or forfeited during the nine months of 2006. The awards are remeasured at each reporting date. At September 30, 2006, the Company had 18,750 unvested phantom performance-based liability awards with an aggregate fair value of $0.6 million. The phantom performance-based awards pay cash bonuses per vested share equal to the average of the highest and lowest selling price on March 1, 2010. The number of shares that will vest will be determined based on the compounded annual growth rate of the Company's per share funds from operations ("FFO") as determined by comparing the per share FFO for the year ended December 31, 2009 with the per share FFO for the year ended December 31, 2005. The Company must achieve compounded annual growth of at least 5% in order for the recipients to receive any amount of the award and at least 9% to receive the entire share award. The Company recognizes expense related to phantom performance-based liability awards based on an estimate of the number of phantom performance-based shares that will ultimately vest. For the nine months ended September 30, 2006, compensation expense of $0.1 million was recognized for the phantom performance-based liability awards based on an estimated vesting of 46.67% of the award on March 1, 2010. 10

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 2. SHARE BASED COMPENSATION, CONTINUED; DIRECTOR OPTION AWARDS The Company also has a 2004 Non-Employee Director Option Plan ("Director Plan") which authorizes the issuance of up to 100,000 options to non-employee directors. At September 30, 2006, the Company had 84,000 options awarded under the Director Plan and a predecessor plan. Of these, 15,000 are unvested of which 7,500, 5,000, and 2,500 shares will vest in the second quarter of 2007, 2008 and 2009, respectively. The remaining unrecognized expense related to these options is $0.04 million which will be recognized over the weighted average remaining vesting period of 1.3 years. For the nine months ended September 30, 2006, the Company recognized $0.03 million of compensation expense related to these director options. The fair value of the options issued is estimated on the date of grant using the Binomial (lattice) option pricing model, with the following assumptions used for the grants for the period indicated: NINE MONTHS ENDED SEPTEMBER 30, 2006 NINE MONTHS --------------------- ENDED MARCH 2006 MAY 2006 SEPTEMBER 30, AWARD AWARD 2005 ---------- -------- ------------- Estimated fair value per share of options granted during year: $ 3.59 $ 2.31 N/A Assumptions: Annualized dividend yield 7.19% 8.20% N/A Common stock price volatility 17.04% 17.05% N/A Risk-free rate of return 4.68% 5.05% N/A Expected option term (in years) 7.5 7.5 N/A The following table summarizes the Director option activity for the nine months ended September 30, 2006: WEIGHTED AVERAGE WEIGHTED AVERAGE AGGREGATE NUMBER OF EXERCISE PRICE CONTRACTUAL TERM INTRINSIC VALUE SHARES (PER COMMON SHARE) (IN YEARS) (IN 000'S) --------- ------------------ ---------------- --------------- Options outstanding at January 1, 2006 71,500 $33.63 Granted 15,000 $33.84 Exercised (2,500) $26.50 Canceled -- ------ Options outstanding at September 30, 2006 84,000 $33.88 4.1 $246 ====== Options vested and expected to vest 84,000 $33.88 4.1 $246 ====== Options exercisable at September 30, 2006 69,000 $33.87 3.1 $202 ====== 11

The transaction included the assumption of $4.5 million of debt. The Company allocates the purchase price of properties to net tangible and identified intangible assets acquired based on their fair values in accordance with the provisions of SFAS No. 141. In making estimates of fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including analysis of recently acquired and existing comparable properties in our portfolio, independent appraisals if obtained in connection with the acquisition or financing of the respective property, and other market data. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets (including in-place leases) acquired. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets.

The Company recognized a gain on the sale of these notes of $0.02 million. Officer's notes, presented as a reduction to stockholders' equity in the balance sheet, are 10 year, LIBOR + 1.75% notes, with a minimum and maximum interest rate of 6% and 9%, respectively. The notes become due in three equal installments on each of December 2008, 2009 and 2010. The following table sets forth certain information regarding officer's notes as of September 30, 2006 (in thousands except for shares and units): SECURED BY OUTSTANDING ------------------------------ PROMISSORY NOTES PRINCIPAL BALANCE COMMON STOCK COMMON OP UNITS ---------------- ----------------- ------------ --------------- Secured - $1.3 million $1,059 65,158 -- Secured - $6.6 million 5,379 144,680 104,085 Secured - $1.0 million 833 77,025 -- Unsecured - $1.0 million 833 -- -- Unsecured - $1.3 million 1,059 -- -- ------ ------- ------- $9,163 286,863 104,085 ====== ======= ======= 13

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 4. NOTES AND OTHER RECEIVABLES, CONTINUED: The officer's personal liability on the secured promissory notes is limited to all accrued interest on such notes plus fifty percent (50%) of the deficiency, if any, after application of the proceeds from the sale of the secured shares and/or the secured units to the then outstanding principal balance of the promissory notes. The unsecured notes are fully recourse to the officer. The reduction in the aggregate principal balance of these notes was $0.3 million for the nine months ended September 30, 2006 and 2005. During an internal review, it was determined that an officer was subject to an increased interest rate due to technical default. The amount has been paid. 5. INVESTMENT IN AFFILIATE: Origen Financial, Inc. ("Origen") is a real estate investment trust in the business of originating, acquiring and servicing manufactured home loans. In October 2003, the Company purchased 5,000,000 shares of common stock of Origen for $50 million. The Company owns approximately 20% of Origen at September 30, 2006 and its investment is accounted for using the equity method of accounting. Equity earnings recorded through September 30, 2006 reflect the Company's estimate of its portion of the anticipated earnings of Origen for the periods ending September 30, 2006 and the Company's adjustments for estimates made in prior quarters based on the actual reported results of Origen for such prior quarters. 6.

The mortgage notes totaling $99.3 million at September 30, 2006 are collateralized by 15 communities comprising approximately 4,611 sites representing approximately $157.2 million of net book value. 14

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 6. DEBT, CONTINUED: The Company has an unsecured revolving line of credit with a maximum borrowing capacity of $115 million bearing interest at LIBOR + 1.75%. The outstanding balance on the line of credit at September 30, 2006 was $90.5 million. In addition, $3.4 million of availability was used to back standby letters of credit leaving a maximum of $21.1 million available to be drawn under the facility. In March of 2006, the Company closed on a $40.0 million floor plan facility that allows for draws on new and pre-owned home purchases and on the Company's portfolio of rental homes. At September 30, 2006 the outstanding balance on the floorplan was $0.1 million. In May of 2006, the Company redeemed $8.2 million of Preferred OP units. During the quarter the Company completed financings totaling $48 million. The 10 year notes have interest only payments at a rate of 6.159 percent and are secured by three communities. The proceeds from the financings were used to repay approximately $12 million of mortgage notes and pay down $36 million of the company's lines of credit. Also during the quarter, the Company notified the lender of its intention to defease a $39.5 million loan cross collateralized by seven properties. One of the properties will be refinanced and the Company has entered into rate lock agreements at a blended rate of 5.796 percent on principal of $52.0 million. The Company paid a rate lock deposit of $520,000. The transaction is anticipated to close by mid- November. At September 30, 2006, the total of maturities and amortization of debt during the next five years, prior to the anticipated transaction described above, are approximately as follows: 2007 -- $76.3 million; 2008 - $15.9 million; 2009 - $25.7 million, 2010 - $21.6 million; 2011 - $121.3 million and $811.8 million thereafter. The most restrictive of these debt agreements place limitations on secured and unsecured borrowings and contain minimum debt service coverage, leverage, distribution and net worth requirements. At September 30, 2006 and 2005, all covenants were met. 15

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 $5.0 million annually. This seasonal revenue is recognized approximately 60% in the first quarter, 5% in both the second and third quarters and 30% in the fourth quarter of each fiscal year. 17

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 4.84 percent. A second swap matures in July 2012, with an effective fixed rate of 5.28 percent. The third swap matures in July 2007, with an effective fixed rate of 3.88 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 matured on April 3, 2006 and was replaced with a new interest rate cap agreement that has a cap rate of 11.79 percent, a notional amount of $152.4 million and a termination date of May 29, 2007. 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 is reflected as a component of interest expense. The valuation adjustment decreased interest expense by $0.2 million and increased interest expense by $0.4 million for the nine months ended September 30, 2006 and 2005, 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 an asset of $0.5 million and less than $0.01 million as of September 30, 2006 and December 31, 2005, 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. 18

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 10. DISPOSITION OF PROPERTIES: During the second quarter of 2005, the Company sold two properties located in Florida comprised of 96 manufactured housing sites and 165 recreational vehicle sites for a combined sales price of $5.7 million. These transactions resulted in a $0.8 million gain. In accordance with SFAS 144, "Accounting for the Impairment or Disposal of Long--Lived Assets" effective for financial statements issued for all fiscal years beginning after December 15, 2001, results of operations and gain/(loss) on sales of real estate for properties with identifiable cash flows sold subsequent to December 31, 2001 are reflected in the Consolidated Statements of Operations as income from discontinued operations for all periods presented.

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 12. COMMITMENTS AND 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), ("SunChamp"), filed a complaint against the Company, SunChamp, 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. These proceedings were stayed by the Superior Court of Guilford County, North Carolina in 2004 pending final determination by the Circuit Court of Oakland County, Michigan as to whether the dispute should be submitted to arbitration and the conclusion of all appeals therefrom. On April 4, 2005, the Oakland County Circuit Court issued a final order compelling arbitration for certain claims brought in the North Carolina case but denying arbitration for certain other claims in the North Carolina case. Shortly thereafter, the Company appealed this decision with respect to the claims for which the court denied arbitration and such appeal is currently pending in the Michigan Court of Appeals. As announced on February 27, 2006, the U.S. Securities and Exchange Commission (the "SEC") completed its inquiry regarding the Company's accounting for its SunChamp investment during 2000, 2001 and 2002, and the Company and the SEC entered into an agreed-upon Administrative Order (the "Order"). The Order required that the Company cease and desist from violations of certain non intent-based provisions of the federal securities laws, without admitting or denying any such violations. The Order included the following findings by the SEC, entered without admission or denial by the Company: (a) the Company's sales of equity interests in SunChamp to third-party investors in 2000 and 2001 should have been disregarded for purposes of allocating losses and, as a result, the Company should have recognized its proportionate share of SunChamp losses during the applicable periods in accordance with the equity method of accounting; and (b) the SunChamp losses should have been reflected in the period incurred, rather than applying a ninety (90) day lag. As a result of these findings, the SEC concluded that the Company overstated its net income for the years ended December 31, 2000, 2001 and 2002 by approximately $3.7 million, $4.7 million and $2.7 million, respectively. In correspondence with the SEC subsequent to the entry of the Order, the SEC has asked the Company to expand its financial statement disclosure to include more specific details relating to the SEC's findings and to disclose the Company's basis for determining that restating its financial statements is not necessary in light of those findings. Those discussions with the SEC are ongoing. The Company has considered the effect of the SEC's findings in the Order on its financial disclosure and overall disclosure obligations. After review and analysis, the Company has determined not to revise its financial statements because management believes that the impact of the findings is not material, either quantitatively or qualitatively, to the Company's financial statements as a whole. 21

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 12. COMMITMENTS AND CONTINGENCIES, CONTINUED: On February 27, 2006, the SEC filed a civil action against the Company's Chief Executive Officer, Chief Financial Officer and a former controller in the United States District Court for the Eastern District of Michigan alleging various claims generally consistent with the SEC's findings set forth in the Order. This action is still in a preliminary stage in which answers have been filed but discovery has not yet commenced. The Company continues to indemnify such employees for all costs and expenses incurred in connection with such civil action. 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 entered into two rate lock agreements related to a financing that will be collateralized by two communities. The Company paid a rate lock deposit of $195,000 to lock the interest rate of 5.83 percent on $19.5 million in principal and a rate lock deposit of $160,000 to lock the interest rate of 5.86 percent on $16 million in principal for a period of 85 days. Also subsequent to quarter end, the Company repaid $4.6 million of debt that was collateralized by one community. 14. RECENT ACCOUNTING PRONOUNCEMENTS: On July 13, 2006 the Financial Accounting Standards Board issued Interpretation (FIN 48), Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109. FIN 48 prescribes a consistent recognition threshold and measurement standard, as well as clear criteria for subsequently recognizing, derecognizing and measuring tax positions for financial statement purposes. FIN 48 also requires expanded disclosure with respect to the uncertainty of income taxes. FIN 48 is effective for fiscal years beginning after December 15, 2006 and must therefore be adopted by the Company for its fiscal year ended December 31, 2007. Management is currently evaluating the impact of FIN 48. In September 2006, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 108 (SAB 108). Due to diversity in practice among registrants, SAB 108 expresses SEC staff views regarding the process by which misstatements in financial statements are evaluated for purposes of determining whether financial statement restatement is necessary. SAB 108 is effective for fiscal years ending after November 15, 2006, and early application is encouraged. The Company does not believe SAB 108 will have a material impact on our results from operations or financial position. In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements" (SFAS No. 157). SFAS No. 157 establishes a common definition for fair value to be applied to US GAAP guidance requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. The Company is currently assessing the impact of SFAS No. 157 on its consolidated financial position and results of operations. 22

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 results of operations under different conditions or using different assumptions. Details regarding the Company's significant accounting policies are described fully in the Company's 2005 Annual Report filed with the Securities and Exchange Commission on Form 10-K. During the nine months ended September 30, 2006, there have been no material changes to the Company's significant accounting policies that impacted the Company's financial condition or results of operations except for the adoption of Financial Accounting Standards Board ("FASB") Statement No. 123 (revised December 2004), Share-Based Payment ("SFAS 123(R)"). In December 2004, FASB issued SFAS 123(R). SFAS 123(R) replaces FASB Statement No. 123 ("Statement 123"), Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25 ("APB 25"), Accounting for Stock Issued to Employees. SFAS 123(R) requires compensation costs related to share-based payment transactions be recognized in the financial statements. The Company adopted SFAS 123(R) effective January 1, 2006 using the "modified prospective" method. Therefore, prior period statements have not been restated. Under this method, in addition to reflecting compensation expense for new-share based awards, expense is also recognized to reflect the remaining service period of awards that had been included in pro-forma disclosures in prior periods. With the adoption of SFAS 123(R), the Company is required to record the fair value of stock-based compensation awards as an expense. In order to determine the fair value of stock options on the grant date, the Company applies the Binomial (lattice) option-pricing model. Inherent in this model are assumptions related to expected stock-price volatility, option life, risk-free interest rate and dividend yield. While the risk-free rate and dividend yield are less subjective assumptions, typically based on factual data derived from public sources, the expected stock-price volatility and option life assumptions require a greater level of judgment which make them critical accounting estimates. The Company uses an expected stock-price volatility assumption that is based on historical implied volatilities of the underlying stock which is obtained from public data sources. With regard to the weighted-average option life assumption, the Company considers the exercise behavior of past grants and models the pattern of aggregate exercises. Patterns are determined on specific criteria of the aggregate pool of optionees. The Company uses the resources of an outside consultant for valuing its options. Two awards of 7,500 options each were made to the Company's non-employee directors during the nine months ended September 30, 2006. Performance-based awards vest based upon the achievement of certain performance conditions and the Company makes its best estimate as to the ultimate achievement of such performance conditions. 23

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS Comparison of the three months ended September 30, 2006 and 2005 For the three months ended September 30, 2006, loss from operations before minority interest increased by $0.2 million from $(4.2) million to $(4.4) million, when compared to the three months ended September 30, 2005. The increased loss was due to increased expenses of $3.3 million, offset by increased revenues of $1.7 million and increased equity income from affiliate of $1.4 million as described in more detail below. Income from rental property increased by $1.7 million from $44.0 million to $45.7 million, or 3.9 percent, due to acquisitions ($0.3 million) and rent increases and other community revenues ($1.4 million). Revenues from home sales decreased by $1.2 million from $6.0 million to $4.8 million, or 20.0 percent. The decrease in revenues was due to consumer demand shifting to pre-owned homes. The Company sold 135 manufactured homes during the third quarter of 2006 of which 17 percent were new homes, as compared to 132 sales during the same period in 2005 of which approximately 47 percent were new homes. Rental home revenue increased by $1.4 million from $2.6 million to $4.0 million. The number of tenants in the Company's rental program increased from 3,438 at September 30, 2005 to 4,659 at September 30, 2006, resulting in additional revenue of approximately $1.1 million. The remainder of the increase resulted from an increase in the average rental rate per home from $634 per month at September 30, 2005 to $678 per month at September 30, 2006. Ancillary revenues, net decreased by approximately $0.1 million due primarily to an increase in golf course management fees. Interest income increased by $0.3 million due primarily to an increase in interest on officer's notes as discussed in footnote # 4. Other income decreased by $0.4 million from a loss of $(0.2) million to a loss of $(0.6) million due primarily to an increase in the loss associated with the disposition of miscellaneous assets. Property operating and maintenance expenses increased by $0.6 million from $11.7 million to $12.3 million, or 5.1 percent. The increase was due to increases in utility costs ($0.3 million), health insurance costs ($0.3 million) and property insurance cost ($0.1 million), partially offset by decreases in repair and maintenance ($0.1 million). Real estate taxes increased by $0.2 million due to increases in assessments and tax rates. Cost of home sales decreased by $1.1 million from $4.8 million to $3.7 million, or 23 percent due to the increase in the number of pre-owned homes sold and decrease in the number of new homes sold. The Company sold 135 manufactured homes during the third quarter of 2006 of which only 17 percent were new homes, as compared to 132 sales during the same period in 2005 of which approximately 47 percent were new homes. Gross profit margins increased from 20.4 percent in 2005 to 21.6 percent in 2006. Rental home operating and maintenance expense increased by $1.1 million from $1.9 million to $3.0 million, or 57.9 percent due primarily to an increase in the number of tenants in the Company's rental program. 24

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: General and administrative expenses for rental property decreased by $0.2 million from $3.6 million to $3.4 million, or 5.6 percent, due primarily to a decrease in legal expenses $(0.4 million) partially offset by an increase in consulting expenses ($0.1 million) and an increase in Michigan Single Business Tax expense ($0.1 million). General and administrative expenses for home sales and rentals decreased by $0.2 million from $1.8 million to $1.6 million, or 11.1 percent. The decrease was due to decreases in payroll and commissions ($0.1 million) and a decrease in other miscellaneous expenses ($0.1 million). Depreciation and amortization increased by $1.6 million from $13.5 million to $15.1 million, or 11.8 percent, due primarily to an increase in the total rental home portfolio. Interest expense increased by $1.3 million from $15.2 million to $16.5 million, or 8.6 percent, primarily due to increased debt levels at higher variable rates. Comparison of the nine months ended September 30, 2006 and 2005 For the nine months ended September 30, 2006, loss from operations before minority interest increased by $3.4 million from a loss of $(4.2) million to a loss of $(7.6) million, when compared to the nine months ended September 30, 2005. The increase was due to increased expenses of $17.6 million, partially offset by increased revenues of $12.2 million and increased equity income from affiliate of $2.0 million as described in more detail below. Income from rental property increased by $5.9 million from $133.4 million to $139.3 million, or 4.4 percent, due to acquisitions ($1.3 million) and rent increases and other community revenues ($4.6 million). Revenues from home sales increased by $1.2 million from $14.1 million to $15.3 million, or 8.5 percent. The Company sold 366 manufactured homes during the nine months ended September 30, 2006 as compared to 342 sales during the same period in 2005. The increase in the number of homes sold resulted in additional revenue of approximately $1.0 million. The remainder of the increase resulted from an increase in the average selling price per home. Rental home revenue increased by $4.9 million from $6.2 million to $11.1 million. The number of tenants in the Company's rental program increased from 3,438 at September 30, 2005 to 4,659 at September 30, 2006, resulting in additional revenue of approximately $3.5 million. The remainder of the increase resulted from an increase in the average rental rate per home from $634 per month at September 30, 2005 to $678 per month at September 30, 2006. Ancillary revenues, net, decreased by $0.3 million from $0.6 million to $0.3 million due to a non-refundable option payment received in 2005 ($0.2 million) and increased golf course management fees ($0.1 million). Interest income decreased by $0.7 million from $3.6 million to $2.9 million, or 19.4 percent, due primarily to a decrease in interest earned on the Company's short-term investments and a decrease in the amount of interest earning notes and receivables. 25

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: Other income increased by $1.2 million from a loss of $(0.4) million to income of $0.8 million due to an increase in brokerage commissions ($0.1 million), a decrease in unsuccessful acquisition expenses ($0.3 million), proceeds from a lawsuit settlement ($0.4 million) and an increase in other miscellaneous operating income ($0.4 million). Property operating and maintenance expenses increased by $1.3 million from $34.2 million to $35.5 million, or 3.8 percent. The increase was due to acquisitions ($0.4 million), increases in utility costs ($1.2 million) and payroll and health insurance costs ($0.4 million), partially offset by decreases in repair and maintenance ($0.3 million) and other miscellaneous expenses ($0.4 million). Real estate taxes increased by $0.4 million from $11.4 million to $11.8 million, or 3.5 percent, due to acquisitions ($0.1 million) and increases in assessments and tax rates ($0.3 million). Cost of home sales increased by $1.2 million from $10.8 million to $12.0 million, or 11.1 percent due primarily to the increase in the number of homes sold. The Company sold 366 manufactured homes during the nine months ended September 30, 2006 as compared to 342 sales during the same period in 2005. The increase in the number of homes sold resulted in additional costs of approximately $0.8 million. The remainder of the increase resulted from an increase in the average cost per home. Gross profit margins decreased from 23.8 percent in 2005 to 22.0 percent in 2006 due to increased sales of pre-owned homes at lower margins partially offset by improved margins on new home sales. Rental home operating and maintenance expense increased by $3.3 million from $4.8 million to $8.1 million, or 68.7 percent due primarily to an increase in the number of tenants in the Company's rental program. General and administrative expenses for rental property increased by $2.1 million from $10.7 million to $12.8 million, or 19.6 percent, due to an increase in payroll and benefits ($1.8 million) that includes the accrual of annual performance based bonus incentives and initial recognition of expense related to performance-based restricted and phantom stock awards, and an increase in expenditures related to a review of the Company's strategic alternatives ($0.3 million). General and administrative expenses for home sales and rentals decreased by $0.2 million from $4.9 million to $4.7 million, or 4.1 percent due primarily to a decrease in miscellaneous operating expenses. Depreciation and amortization increased by $4.8 million from $40.0 million to $44.8 million, or 12.0 percent, due primarily to an increase in the total rental home portfolio. Interest expense increased by $4.1 million from $44.5 million to $48.6 million, or 9.2 percent, primarily due to increased debt levels at higher variable rates. 26

SUN COMMUNITIES, INC. ITEM 2. 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 nine months ended September 30, 2006 and 2005. The "Same Property" data represents information regarding the operation of communities owned as of January 1, 2005 and September 30, 2006. 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) Occupied sites include manufactured housing and permanent recreational vehicle sites, and exclude seasonal recreational vehicle sites. (3) Occupancy % and weighted average rent relates to manufactured housing sites, excluding recreational vehicle sites. 27

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS, CONTINUED: On a same property basis, property net operating income increased by $3.6 million from $89.5 million to $93.1 million, or 4.0 percent. Income from rental property increased by $4.5 million from $127.3 million to $131.8 million, or 3.5 percent, due primarily to increases in rents including water and property tax pass through. Property operating expenses increased by $0.9 million from $37.8 million to $38.7 million, or 2.4 percent, due primarily to increases in real estate taxes and utilities costs. RENTAL PROGRAM The following tables reflect additional information regarding the Company's rental program for the periods ended and as of September 30, 2006 and 2005: THREE MONTHS ENDED NINE MONTHS ENDED SEPTEMBER 30, SEPTEMBER 30, ------------------ ----------------- 2006 2005 2006 2005 ------ ------ ------- ------- Rental home revenue $3,965 $2,549 $11,107 $ 6,181 Site rent included in Income from rental property 4,957 3,383 13,839 8,482 ------ ------ ------- ------- Rental program revenue 8,922 5,932 24,946 14,663 Expenses Payroll and commissions 503 388 1,525 1,214 Repairs and refurbishment 1,324 955 3,315 2,105 Taxes and insurance 642 176 1,860 724 Other 496 370 1,443 811 ------ ------ ------- ------- Rental program operating and maintenance 2,965 1,889 8,143 4,854 ------ ------ ------- ------- Net operating income (1) $5,957 $4,043 $16,803 $ 9,809 ====== ====== ======= ======= (1) See Note (1) following Same Property Information OCCUPIED RENTAL HOMES INFORMATION (IN THOUSANDS EXCEPT FOR *): 2006 2005 -------- ------- Number of occupied rentals, end of period* 4,659 3,438 Cost of occupied rental homes $138,053 $97,827 Weighted average monthly rental rate* $ 678 $ 634 Net operating income from the rental program increased $1.9 million from $4.0 million to $5.9 million in the third quarter of 2006 as a result of a $3.0 million increase in revenue offset by a $1.1 million increase in expenses. Revenues increased due to an increase in the weighted average monthly rental rate and an increase in the number of leased rental homes. Expenses were also impacted by the increase in the number of leased rental homes. 28

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, capital improvements of properties, the purchase of new and pre-owned homes, property acquisitions, development and expansion of properties, and debt repayment. The Company expects to meet its short-term liquidity requirements through its working capital provided by operating activities, its $115.0 million line of credit and its $40.0 million floor plan. 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 has invested approximately $2.4 million in its development communities for the nine months ended September 30, 2006 consisting primarily of costs necessary to complete home site improvements such as driveways, sidewalks, piers, pads and runners and anticipates investing an additional $0.5 - $1.0 million for such costs during the remainder of 2006. The Company expects to finance these investments by using net cash flows provided by operating activities and by drawing upon its lines of credit. The Company has invested $7.8 million ($3.3 million cash and $4.5 million in assumed debt) in the acquisition of properties during 2006. Although substantial acquisitions are not anticipated prior to year end, the Company continuously seeks acquisition opportunities that meet the Company's criteria for acquisition. Should such investment opportunities arise the Company will finance the acquisitions though the temporary use of its line of credit until permanent secured financing can be arranged, through the assumption of existing debt on the properties or the issuance of certain equity securities. The Company has also invested approximately $32.2 million during the nine months ended September 30, 2006 in homes primarily intended for its rental program. Expenditures for the remainder of 2006 will be dependent upon the condition of the markets for the purchase of value priced repossessions in our communities and the purchase of new homes for sale to new residents. Cash and cash equivalents decreased by $1.8 million from $5.9 million at December 31, 2005 to $4.1 million at September 30, 2006. Net cash provided by operating activities decreased by $1.3 million to $42.0 million for the nine months ended September 30, 2006 compared to $43.3 million for the nine months ended September 30, 2005. 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 "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2005. 29

SUN COMMUNITIES, INC. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS LIQUIDITY AND CAPITAL RESOURCES, CONTINUED: 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 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 "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2005. 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 September 30, 2006, the Company's debt to total market capitalization approximated 64.0 percent (assuming conversion of all Common OP Units to shares of common stock). The debt has a weighted average maturity of approximately 6.8 years and a weighted average interest rate of 5.5 percent. Capital expenditures for the nine months ended September 30, 2006 and 2005 included recurring capital expenditures of $5.2 million and $5.5 million, respectively. Net cash used in investing activities increased by $26.2 million to $41.8 million for the nine months ended September 30, 2006 compared to $15.6 million for the nine months ended September 30, 2005. This increase was due to a $44.9 million decrease in net proceeds from sale of short-term investments, a $3.9 million decrease in proceeds related to property dispositions and a $8.3 million decrease in notes receivable and officers' notes, net, offset by decreased investment in rental property of $26.7 million and a $4.2 million increase in proceeds from sale of installment loans on manufactured homes to Origen. Net cash used in financing activities decreased by $74.0 million to $2.0 million for the nine months ended September 30, 2006 compared to $76.0 million used in financing activities for the nine months ended September 30, 2005. This decrease was primarily due to a $41.8 million decrease in payments to retire preferred operating partnership units, a $42.1 million increase in proceeds from notes payable and other debt, a $13.9 million reduction in funds used to purchase Company stock, a $11.4 million reduction in payments made to redeem notes payable and other debt, a $1.0 million decrease in payments to redeem common stock and OP units and a $2.0 million increase in proceeds from option exercises, offset by a decrease of $35.9 million in borrowings on lines of credit, an increase in distributions of $1.6 million and an increase in payments for deferred financing costs of $0.7 million. 30

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 periods ended September 30, 2006 and 2005 (in thousands): 31

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. 32

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 $188.3 million and $146.7 million as of September 30, 2006 and 2005, 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 nine months ended September 30, 2006 and 2005, the Company believes its interest expense would have increased or decreased by approximately $1.9 million and $1.2 million based on the $193.9 million and $121.1 million average balance outstanding under the Company's variable rate debt facilities for the nine months ended September 30, 2006 and 2005, respectively. Additionally, the Company had $13.5 million LIBOR based variable rate mortgage and other notes receivables as of September 30, 2006 and 2005. If LIBOR increased or decreased by 1.0 percent during the nine months ended September 30, 2006 and 2005, the Company believes interest income would have increased or decreased by approximately $0.1 million and $0.1 million based on the $13.5 million and $14.3 million average balance outstanding on all variable rate notes receivable for the nine months ended September 30, 2006 and 2005, respectively. The Company has entered into three separate interest rate swap agreements and an interest rate cap agreement. One of the swap agreements fixes $25 million of variable rate borrowings at 4.84 percent through July 2009, another of the swap agreements fixes $25 million of variable rate borrowings at 5.28 percent 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 3.88 percent through July 2007. The interest rate cap agreement has a cap rate of 11.79 percent, a notional amount of $152.4 million and a termination date of May 29, 2007. Each of the Company's derivative contracts is based upon 90-day LIBOR. 34

(b) There have been no changes in the Company's internal control over financial reporting during the quarterly period ended September 30, 2006, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. 35
