As used in this report, "Company", "Us", "We", "Our" and similar terms means Sun Communities, Inc., a Maryland corporation, and one or more of its subsidiaries (including the Operating Partnership (as defined below)). PART I ITEM 1. BUSINESS GENERAL We are a self-administered and self-managed real estate investment trust, or REIT. We own, operate, develop and finance manufactured housing communities concentrated in the midwestern and southeastern United States. We are a fully integrated real estate company which, together with our affiliates and predecessors, have been in the business of acquiring, operating and expanding manufactured housing communities since 1975. As of December 31, 2003, we owned and operated a portfolio of 127 properties located in seventeen states (the "Properties"), including 115 manufactured housing communities, five recreational vehicle communities, and seven properties containing both manufactured housing and recreational vehicle sites. As of December 31, 2003, the Properties contained an aggregate of 43,875 developed sites comprised of 38,797 developed manufactured home sites and 5,078 recreational vehicle sites and an additional 6,756 manufactured home sites suitable for development. In order to enhance property performance and cash flow, the Company, through Sun Home Services, Inc., a Michigan corporation ("SHS"), actively markets, sells and leases new and pre-owned manufactured homes for placement in the Properties. Our executive and principal property management office is located at 27777 Franklin Road, Suite 200, Southfield, Michigan 48034 and our telephone number is (248) 208-2500. We have regional property management offices located in Austin, Texas; Dayton, Ohio; Grand Rapids, Michigan; Elkhart, Indiana; and Orlando, Florida, and we employed an aggregate of 611 people as of December 31, 2003. Our website address is www.suncommunities.com and we make available, free of charge, on or through our website all of our periodic reports, including our annual report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, as soon as reasonably practicable after we file such reports with the Securities and Exchange Commission. RECENT DEVELOPMENTS Acquisitions. During 2003, we acquired one community in Michigan for approximately $4.5 million comprised of $2.2 million in cash and $2.3 million in debt. When fully developed, the property will consist of 242 manufactured housing sites. In 2004, we entered into an agreement with certain affiliates of Property Asset Management Inc. ("PAMI") to acquire all of the equity interests in partnerships that directly and indirectly own and operate 19 properties and entered into a real estate purchase agreement to acquire 7 other properties. The properties are recreational vehicle communities, some of which include manufactured home sites. The portfolio consists of 11,331 sites, including 10,586 developed sites and 745 expansion recreational vehicle sites. Completion of the purchases is subject to customary closing conditions. 2

PAMI, the seller under the purchase agreements, is the sole general partner and owns a substantial majority of the equity interests in the partnerships that own the properties subject to the purchase agreements. PAMI has exercised its rights under the relevant partnership agreements to acquire the equity interests of its minority partner. PAMI has informed us that its minority partner has disputed PAMI's rights to purchase its interests under the partnership agreements. As a result, PAMI has filed suit in the Delaware Chancery Court requesting, among other things, that the court specifically enforce PAMI's right to purchase the minority interests. The minority partner in the partnerships has filed an answer and counterclaim in the case requesting that the court find that the minority partner has the right to buy PAMI's interests under the partnership agreements. PAMI believes that it will be successful in the litigation and we expect to complete the acquisition of the partnership interests and properties. However, due to the uncertain nature of litigation and the other conditions to closing, we can provide no assurance that we will be able to successfully complete the proposed acquisitions and cannot reliably predict the timing of the resolution of these matters. Dispositions. The Company closed on the sale of four properties during 2003 realizing gross proceeds of approximately $24.8 million. The properties were located in Michigan and Illinois and comprised 731 sites of which 659, or 90 percent, were occupied. Origen. Previously, we, along with two other participants, provided financing (a line of credit and term loan) to Origen Financial, LLC ("Origen"), a financial services company that provides and services loans used by consumers to finance the purchase of manufactured homes. In October of 2003, Origen completed a $150.0 million private equity offering and repaid its line of credit and term loan in full. We have no continuing obligation to provide financing to Origen. Concurrent with this transaction, we invested $50.0 million in Origen's parent, Origen Financial, Inc. ("Origen, Inc") and agreed to sell Origen, Inc. various interests in manufactured home loans previously acquired from Origen, none of which have been sold as of December 31, 2003. As of December 31, 2003, our investment in Origen, Inc. approximated a one third ownership interest which was accounted for using the equity method of accounting for periods ending after September 30, 2003. STRUCTURE OF THE COMPANY Structured as an umbrella partnership REIT, or UPREIT, Sun Communities Operating Limited Partnership, a Michigan limited partnership (the "Operating Partnership"), is the entity through which we conduct substantially all of our operations, and which owns, either directly or indirectly through subsidiaries, all of our assets (the subsidiaries, collectively with the Operating Partnership, the "Subsidiaries"). This UPREIT structure enables us to comply with certain complex requirements under the Federal tax rules and regulations applicable to REITs, and to acquire manufactured housing communities in transactions that defer some or all of the sellers' tax consequences. We are the sole general partner of, and, as of December 31, 2003, held approximately 88.5% of the interests (not including preferred limited partnership interests) in, the Operating Partnership. The Subsidiaries also include SHS, which provides manufactured home sales and other services to current and prospective tenants of the Properties. Along with several other subsidiaries, SHS owns Sun Water Oak Golf, Inc., which was organized to own and operate 3

the golf course, restaurant and related facilities located on the Water Oak Property that was acquired in December 1993. See "Factors that May Affect Future Results -- Some of our directors and officers may have conflicts of interest with respect to certain related party transactions and other business interests." THE MANUFACTURED HOUSING COMMUNITY INDUSTRY A manufactured housing community is a residential subdivision designed and improved with sites for the placement of manufactured homes and related improvements and amenities. Manufactured homes are detached, single-family homes which are produced off-site by manufacturers and installed on sites within the community. Manufactured homes are available in a wide array of designs, providing owners with a level of customization generally unavailable in other forms of multifamily housing. Modern manufactured housing communities, such as the Properties, contain improvements similar to other garden-style residential developments, including centralized entrances, paved streets, curbs and gutters, and parkways. In addition, these communities also often provide a number of amenities, such as a clubhouse, a swimming pool, shuffleboard courts, tennis courts, laundry facilities and cable television service. The owner of each home on our Properties leases the site on which the home is located. We own the underlying land, utility connections, streets, lighting, driveways, common area amenities and other capital improvements and are responsible for enforcement of community guidelines and maintenance. Some of the Properties provide water and sewer service through public or private utilities, while others provide these services to residents from on-site facilities. Each owner within our Properties is responsible for the maintenance of the home and leased site. As a result, capital expenditure needs tend to be less significant, relative to multi-family rental apartment complexes. PROPERTY MANAGEMENT Our property management strategy emphasizes intensive, hands-on management by dedicated, on-site district and community managers. We believe that this on-site focus enables us to continually monitor and address tenant concerns, the performance of competitive properties and local market conditions. Of the 611 Company employees, 522 are located on-site as property managers, support staff, or maintenance personnel. Our community managers are overseen by Brian W. Fannon, Chief Operating Officer, who has 34 years of property management experience, three Vice Presidents of Operations and seventeen Regional Vice Presidents. In addition, the Regional Vice Presidents are responsible for semi-annual market surveys of competitive communities, interaction with local manufactured home dealers and regular property inspections. Each district or community manager performs regular inspections in order to continually monitor the Property's physical condition and provides managers with the opportunity to understand and effectively address tenant concerns. In addition to a district or community manager, each district or property has an on-site maintenance personnel and management support staff. We hold periodic training sessions for all property management personnel to ensure that management policies are implemented effectively and professionally. 4

HOME SALES AND LEASING SHS offers manufactured home sales services to tenants and prospective tenants of our Properties. Since tenants often purchase a home already on-site within a community, such services enhance occupancy and property performance. Additionally, because many of the homes on the Properties are sold through SHS, better control of home quality in our communities can be maintained than if sales services were conducted solely through third-party brokers. SHS also leases homes to prospective tenants. REGULATIONS AND INSURANCE General. Manufactured housing community properties are subject to various laws, ordinances and regulations, including regulations relating to recreational facilities such as swimming pools, clubhouses and other common areas. We believe that each Property has the necessary operating permits and approvals. Insurance. Our management believes that the Properties are covered by adequate fire, flood, property and business interruption insurance provided by reputable companies with commercially reasonable deductibles and limits. We maintain a blanket policy that covers all of our Properties. We have obtained title insurance insuring fee title to the Properties in an aggregate amount which we believe to be adequate. CORPORATE GOVERNANCE We have implemented the following corporate governance initiatives to address certain legal requirements promulgated under the Sarbanes-Oxley Act of 2002, as well as the recently adopted New York Stock Exchange corporate governance listing standards: - Our Board of Directors determined that Paul D. Lapides, the Chairman of the Audit Committee, qualifies as an "audit committee financial expert" as such term is defined under Item 401 of Regulation S-K. Mr. Lapides is "independent" as that term is used in Item 7(d)(3)(iv) of Schedule 14A under the Exchange Act. - Our Audit Committee adopted our Audit and Non-Audit Services Pre-Approval Policy, which sets forth the procedures and the conditions pursuant to which permissible services to be performed by our independent public accountants may be pre-approved. - Our Board of Directors adopted a Financial Code of Ethics for Senior Financial Officers, which governs the conduct of our senior financial officers. A copy of this code is available on our website at www.suncommunities.com under the heading "Shareholder Info", "Company Info" and subheading "Governance" and is also available in print to any stockholder upon written request addressed to Investor Relations, Sun Communities, Inc., 27777 Franklin Road, Suite 200, Southfield, Michigan 48034. - Our Board of Directors established and adopted new charters for each of its Audit, Compensation and Nominating and Corporate Governance Committees. Each committee is comprised of three (3) independent directors. A copy of each of these charters is available on our website at www.suncommunities.com under the heading "Shareholder Info", "Company Info" and subheading "Governance" and is also available in print to any stockholder upon written request addressed to Investor Relations, Sun Communities, Inc., 27777 Franklin Road, Suite 200, Southfield, Michigan 48034. - Our Board of Directors adopted a Code of Business Conduct and Ethics, which governs business decisions made and actions taken by our directors, officers and employees. A copy of this code is available on our website at www.suncommunities.com under the heading "Shareholder Info", "Company Info" and subheading "Governance" and is also available in print to any 5

stockholder upon written request addressed to Investor Relations, Sun Communities, Inc., 27777 Franklin Road, Suite 200, Southfield, Michigan 48034. - Our Board of Directors adopted Corporate Governance Guidelines, a copy of which is available on our website at www.suncommunities.com under the heading "Shareholder Info", "Company Info" and subheading "Governance" and is also available in print to any stockholder upon written request addressed to Investor Relations, Sun Communities, Inc., 27777 Franklin Road, Suite 200, Southfield, Michigan 48034. FACTORS THAT MAY AFFECT FUTURE RESULTS Our prospects are subject to certain uncertainties and risks. Our future results could differ materially from current results, and our actual results could differ materially from those projected in forward-looking statements as a result of certain risk factors. These risk factors include, but are not limited to, those set forth below, other one-time events, and important factors disclosed previously and from time to time in other Company filings with the Securities and Exchange Commission. This report contains certain forward-looking statements. REAL ESTATE RISKS General economic conditions and the concentration of our properties in Michigan and Florida may affect our ability to generate sufficient revenue. The market and economic conditions in our current markets generally, and specifically in metropolitan areas of our current markets, may significantly affect manufactured home occupancy or rental rates. Occupancy and rental rates, in turn, may significantly affect our revenues, and if our communities do not generate revenues sufficient to meet our operating expenses, including debt service and capital expenditures, our cash flow and ability to pay or refinance our debt obligations could be adversely affected. We derived significant amounts of rental income for the period ended December 31, 2003 from properties located in Michigan and Florida. As of December 31, 2003, 42 of our 127 Properties, or approximately 33%, are located in Michigan, 20 or approximately 16%, are located in Florida and 18 or approximately 14% are located in Indiana. As a result of the geographic concentration of our Properties in Michigan and Florida, we are exposed to the risks of downturns in the local economy or other local real estate market conditions which could adversely affect occupancy rates, rental rates and property values of properties in these markets. The following factors, among others, may adversely affect the revenues generated by our communities: - the national and local economic climate which may be adversely impacted by, among other factors, plant closings and industry slowdowns; 6

- local real estate market conditions such as the oversupply of manufactured housing sites or a reduction in demand for manufactured housing sites in an area; - the number of repossessed homes in a particular market; - the rental market which may limit the extent to which rents may be increased to meet increased expenses without decreasing occupancy rates; - the perceptions by prospective tenants of the safety, convenience and attractiveness of the Properties and the neighborhoods where they are located; - zoning or other regulatory restrictions; - competition from other available manufactured housing sites and alternative forms of housing (such as apartment buildings and site-built single-family homes); - our ability to provide adequate management, maintenance and insurance; - increased operating costs, including insurance premiums, real estate taxes and utilities; or - the enactment of rent control laws or laws taxing the owners of manufactured homes. Our income would also be adversely affected if tenants were unable to pay rent or if sites were unable to be rented on favorable terms. If we were unable to promptly relet or renew the leases for a significant number of the sites, or if the rental rates upon such renewal or reletting were significantly lower than expected rates, then our business and results of operations could be adversely affected. In addition, certain expenditures associated with each equity investment (such as real estate taxes and maintenance costs) generally are not reduced when circumstances cause a reduction in income from the investment. Furthermore, real estate investments are relatively illiquid and, therefore, will tend to limit our ability to vary our portfolio promptly in response to changes in economic or other conditions. Competition affects occupancy levels and rents which could adversely affect our revenues. All of our Properties are located in developed areas that include other manufactured housing community properties. The number of competitive manufactured housing community properties in a particular area could have a material adverse effect on our ability to lease sites and on rents charged at our Properties or at any newly acquired properties. We may be competing with others with greater resources and whose officers and directors have more experience than our officers and directors. In addition, other forms of multi-family residential properties, such as private and federally funded or assisted multi-family housing projects and single-family housing, provide housing alternatives to potential tenants of manufactured housing communities. Our ability to sell manufactured homes may be affected by various factors, which may in turn adversely affect our profitability. Sun Home Services, Inc., a Michigan corporation ("SHS"), is in the manufactured home sales market offering manufactured home sales services to tenants and prospective tenants of our communities. The market for the sale of manufactured homes may be adversely affected by the following factors: 7

- downturns in economic conditions which adversely impact the housing market; - an oversupply of, or a reduced demand for, manufactured homes; - the difficulty facing potential purchasers in obtaining affordable financing as a result of heightened lending criteria; and - an increase in the rate of manufactured home repossessions which provide aggressively priced competition to new manufactured home sales. Any of the above listed factors could adversely impact our rate of manufactured home sales, which would result in a decrease in profitability. Increases in taxes and regulatory compliance costs may reduce our revenue. Costs resulting from changes in real estate tax laws generally may be passed through to tenants and will not affect us. Increases in income, service or other taxes, however, generally are not passed through to tenants under leases and may adversely affect our funds from operations and our ability to pay or refinance our debt. Similarly, changes in laws increasing the potential liability for environmental conditions existing on properties or increasing the restrictions on discharges or other conditions may result in significant unanticipated expenditures, which would adversely affect our business and results of operations. We may not be able to integrate or finance our development activities. We are engaged in the construction and development of new communities, and intend to continue in the development and construction business in the future. Our development and construction business may be exposed to the following risks which are in addition to those risks associated with the ownership and operation of established manufactured housing communities: - we may not be able to obtain financing with favorable terms for community development which may make us unable to proceed with the development; - we may be unable to obtain, or face delays in obtaining, necessary zoning, building and other governmental permits and authorizations, which could result in increased costs and delays, and even require us to abandon development of the community entirely if we are unable to obtain such permits or authorizations; - we may abandon development opportunities that we have already begun to explore and as a result we may not recover expenses already incurred in connection with exploring such development opportunities; - we may be unable to complete construction and lease-up of a community on schedule resulting in increased debt service expense and construction costs; - we may incur construction and development costs for a community which exceed our original estimates due to increased materials, labor or other costs, which could make completion of the community uneconomical and we may not be able to increase rents to compensate for the increase in development costs which may impact our profitability; 8

- we may be unable to secure long-term financing on completion of development resulting in increased debt service and lower profitability; and - occupancy rates and rents at a newly developed community may fluctuate depending on several factors, including market and economic conditions, which may result in the community not being profitable. If any of the above occurred, our business and results of operations could be adversely affected. We may not be able to integrate or finance our acquisitions and our acquisitions may not perform as expected. We acquire and intend to continue to acquire manufactured housing communities on a select basis. Our acquisition activities and their success are subject to the following risks: - we may be unable to acquire a desired property because of competition from other well capitalized real estate investors, including both publicly traded real estate investment trusts and institutional investment funds; - even if we enter into an acquisition agreement for a property, it is usually subject to customary conditions to closing, including completion of due diligence investigations to our satisfaction, which may not be satisfied; - even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price; - we may be unable to finance acquisitions on favorable terms; - acquired properties may fail to perform as expected; - acquired properties may be located in new markets where we face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area and unfamiliarity with local governmental and permitting procedures; and - we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations. If any of the above occurred, our business and results of operations could be adversely affected. In addition, we may acquire properties subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow. Rent control legislation may harm our ability to increase rents. State and local rent control laws in certain jurisdictions may limit our ability to increase rents and to recover increases in operating expenses and the costs of capital improvements. Enactment of such laws has been considered from time to time in other jurisdictions. Certain 9

Properties are located, and we may purchase additional properties, in markets that are either subject to rent control or in which rent-limiting legislation exists or may be enacted. We may be subject to environmental liability. Under various federal, state and local laws, ordinances and regulations, an owner or operator of real estate is liable for the costs of removal or remediation of certain hazardous substances at, on, under or in such property. Such laws often impose such liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous substances. The presence of such substances, or the failure to properly remediate such substances, may adversely affect the owner's ability to sell or rent such property, to borrow using such property as collateral or to develop such property. Persons who arrange for the disposal or treatment of hazardous substances also may be liable for the costs of removal or remediation of such substances at a disposal or treatment facility owned or operated by another person. In addition, certain environmental laws impose liability for the management and disposal of asbestos-containing materials and for the release of such materials into the air. These laws may provide for third parties to seek recovery from owners or operators of real properties for personal injury associated with asbestos-containing materials. In connection with the ownership, operation, management, and development of real properties, we may be considered an owner or operator of such properties and, therefore, are potentially liable for removal or remediation costs, and also may be liable for governmental fines and injuries to persons and property. When we arrange for the treatment or disposal of hazardous substances at landfills or other facilities owned by other persons, we may be liable for the removal or remediation costs at such facilities. All of the Properties have been subject to a Phase I or similar environmental audit (which involves general inspections without soil sampling or ground water analysis) completed by independent environmental consultants. These environmental audits have not revealed any significant environmental liability that would have a material adverse effect on our business. These audits cannot reflect conditions arising after the studies were completed, and no assurances can be given that existing environmental studies reveal all environmental liabilities, that any prior owner or operator of a property or neighboring owner or operator did not create any material environmental condition not known to us, or that a material environmental condition does not otherwise exist as to any one or more Properties. Losses in excess of our insurance coverage or uninsured losses could adversely affect our cash flow. We maintain comprehensive liability, fire, flood (where appropriate), extended coverage, and rental loss insurance on the Properties with policy specifications, limits, and deductibles which are customarily carried for similar properties. As a result of market conditions in the insurance industry, we recently decided to carry a large deductible on our liability insurance. Certain types of losses, however, may be either uninsurable or not economically insurable, such as losses due to earthquakes, riots, or acts of war. In the event an uninsured loss occurs, we could lose both our investment in and anticipated profits and cash flow from the affected property. Any loss would adversely affect our ability to repay our debt. 10

FINANCING AND INVESTMENT RISKS Our significant amount of debt could limit our operational flexibility or otherwise adversely affect our financial condition. We have a significant amount of debt. As of December 31, 2003, we had approximately $773.3 million of total debt outstanding, consisting of approximately $266.2 million in collateralized debt, and approximately $507.1 million in unsecured debt. Included in the collateralized debt outstanding is $256.6 million of indebtedness that is collateralized by mortgage liens on 34 of the Properties and home inventory (the "Mortgage Debt") and one $9.6 million capitalized lease obligation. If we fail to meet our obligations under the Mortgage Debt, the lender would be entitled to foreclose on all or some of the Properties securing such debt which could have a material adverse effect on us and our ability to make expected distributions, and could threaten our continued viability. We are subject to the risks normally associated with debt financing, including the following risks: - our cash flow may be insufficient to meet required payments of principal and interest, or require us to dedicate a substantial portion of our cash flow to pay our debt and the interest associated with our debt rather than to other areas of our business; - our existing indebtedness may limit our operating flexibility due to financial and other restrictive covenants, including restrictions on incurring additional debt; - it may be more difficult for us to obtain additional financing in the future for our operations, working capital requirements, capital expenditures, debt service or other general requirements; - we may be more vulnerable in the event of adverse economic and industry conditions or a downturn in our business; and - we may be placed at a competitive disadvantage compared to our competitors that have less debt. If any of the above risks occurred, our financial condition and results of operations could be materially adversely affected. We may be able to incur substantially more debt which would increase the risks associated with our substantial leverage. Despite our current indebtedness levels, we may still be able to incur substantially more debt in the future. If new debt is added to our current debt levels, an even greater portion of our cash flow will be needed to satisfy our debt service obligations. As a result, the related risks that we now face could intensify and increase the risk of a default on our indebtedness. 11

Our equity investment in Origen Financial, Inc., may subject us to certain risks. In October 2003, Origen Financial, LLC completed a $150 million recapitalization. In this transaction, we purchased 5,000,000 shares of common stock (representing approximately one-third of the issued and outstanding shares of common stock as of December 31, 2003) of Origen Financial, Inc. for $50 million. Origen is a real estate investment trust in the business of originating, acquiring and servicing manufactured home loans. Our equity investment in Origen is subject to all of the risks associated with Origen's business, including the risks associated with the manufactured housing finance industry. The failure of Origen to achieve its development and operating goals could have a material adverse effect on the value of our investment in Origen The financial condition and solvency of our borrowers and the market value of our properties may adversely affect our investments in real estate, installment and other loans. As of December 31, 2003, we had an investment of approximately $41.7 million in real estate loans to several entities and Properties, some of which are secured by a first lien on the underlying property, and others which are secured loans subordinate to the primary lender. Also, as of December 31, 2003, we had outstanding approximately $24.8 million in installment loans to owners of manufactured homes. These installment loans are collateralized by the manufactured homes. We may invest in additional mortgages and installment loans in the future. By virtue of our investment in the mortgages and the loans, we are subject to the following risks of such investment: - the borrowers may not be able to make debt service payments or pay principal when due; - the value of property securing the mortgages and loans may be less than the amounts owed; and - interest rates payable on the mortgages and loans may be lower than our cost of funds. If any of the above occurred, our business and results of operations could be adversely affected. 12

TAX RISKS We may suffer adverse tax consequences and be unable to attract capital if we fail to qualify as a REIT. We believe that since our taxable year ended December 31, 1994, we have been organized and operated, and intend to continue to operate, so as to qualify for taxation as a REIT under the Internal Revenue Code. Although we believe that we have been and will continue to be organized and have operated and will continue to operate so as to qualify for taxation as a REIT, we cannot assure you that we have been or will continue to be organized or operated in a manner to so qualify or remain so qualified. Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which require the Company continually to monitor its tax status. If we fail to qualify as a REIT in any taxable year, we would be subject to federal income tax (including any applicable alternative minimum tax) on our taxable income at regular corporate rates. Moreover, unless entitled to relief under certain statutory provisions, we also would be disqualified from treatment as a REIT for the four taxable years following the year during which qualification was lost. This treatment would reduce our net earnings available for investment or distribution to stockholders because of the additional tax liability to us for the years involved. In addition, distributions to stockholders would no longer be required to be made. Even if we qualify for and maintain our REIT status, we will be subject to certain federal, state and local taxes on our property and certain of our operations. We intend for the Operating Partnership to qualify as a partnership, but we cannot guarantee that it will qualify. We believe that the Operating Partnership has been organized as a partnership and will qualify for treatment as such under the Code. However, if the Operating Partnership is deemed to be a "publicly traded partnership," it will be treated as a corporation instead of a partnership for federal income tax purposes unless at least 90% of its income is qualifying income as defined in the Internal Revenue Code. The income requirements applicable to REITs and the definition of "qualifying income" for purposes of this 90% test are similar in most respects. Qualifying income for the 90% test generally includes passive income, such as specified types of real property rents, dividends and interest. We believe that the Operating Partnership would meet this 90% test, but we cannot guarantee that it would. If the Operating Partnership were to be taxed as a corporation, it would incur substantial tax liabilities, we would fail to qualify as a REIT for federal income tax purposes, and our ability to raise additional capital could be significantly impaired. Our ability to accumulate cash is restricted due to certain REIT distribution requirements. In order to qualify as a REIT, we must distribute to our stockholders at least 90% of our REIT taxable income (calculated without any deduction for dividends paid and excluding net capital gain) and to avoid federal income taxation, our distributions must not be less than 100% of our REIT taxable income, including capital gains. As a result of the distribution requirements, we do not expect to accumulate significant amounts of cash. Accordingly, these distributions could significantly reduce the cash available to us in subsequent periods to fund our operations and future growth. 13

BUSINESS RISKS Some of our directors and officers may have conflicts of interest with respect to certain related party transactions and other business interests. Ownership of SHS. Gary A. Shiffman, the President, Chief Executive Officer and Chairman of the Board of Directors of the Company, and the Estate of Milton M. Shiffman (former Chairman of the Board), are the owners of all of the outstanding common stock of SHS, and as such are entitled to 5% of the cash flow from the operating activities of SHS (we own 100% of the non-voting preferred stock which entitles us to 95% of such cash flow). SHS is consolidated in our financial statements as of December 31, 2003. Arthur A. Weiss, one of our directors, is also a personal representative of the Estate. Thus, in all transactions involving SHS, Mr. Shiffman and Mr. Weiss may have a conflict of interest with respect to their respective obligations as an officer and/or director of the Company and Mr. Shiffman's right and the Estate's right to receive a portion of the cash flow from the operating activities of SHS. The following are the current transactions and agreements involving SHS which may present a conflict of interest for Mr. Shiffman and Mr. Weiss: - the agreement between SHS and Sun for sales, brokerage, and leasing services; - the intercompany loans from the Operating Partnership to SHS; and - the ownership and operation of SHS's other subsidiaries, including Sun Water Oak Golf, Inc. The failure to negotiate these and other transactions or agreements involving SHS on an arm's length basis, or to enforce the material terms of any agreement or arrangement between SHS and us, could have an adverse effect on Sun. Tax Consequences Upon Sale of Properties. Gary A. Shiffman holds limited partnership interests in the Operating Partnership which were received in connection with the contribution of 24 properties from partnerships previously affiliated with him (the "Sun Partnerships"). Prior to any redemption of these limited partnership interests for our common stock, Mr. Shiffman will have tax consequences different from those of us and our public stockholders on the sale of any of the Sun Partnerships. Four of the properties have been sold to date. Therefore, Mr. Shiffman and the Company may have different objectives regarding the appropriate pricing and timing of any sale of those properties. Lease of Executive Offices. Gary A. Shiffman, together with certain family members, indirectly owns approximately a 21% equity interest in American Center LLC, the entity from which we lease office space for our principal executive offices. This lease is for an initial term of five years and we have the right to extend the lease for an additional five year term. The annual base rent under this lease begins at $19.25 per square foot (gross) for the first lease year and increases $0.50 per square foot for each successive year of the initial term. Mr. Shiffman may have a conflict of interest with respect to his obligations as an officer and/or director of the Company and his ownership interest in American Center. 14

We rely on key management. We are dependent on the efforts of our executive officers, particularly Gary A. Shiffman, Jeffrey P. Jorissen, Brian W. Fannon and Jonathan M. Colman (together, the "Senior Officers"). The loss of services of one or more of our executive officers could have a temporary adverse effect on our operations. We do not currently maintain or contemplate obtaining any "key-man" life insurance on the Senior Officers. Certain provisions in our governing documents may make it difficult for a third-party to acquire us. 9.8% Ownership Limit. In order to qualify and maintain our qualification as a REIT, not more than 50% of the outstanding shares of our capital stock may be owned, directly or indirectly, by five or fewer individuals. Thus, ownership of more than 9.8% of our outstanding shares of common stock by any single stockholder has been restricted, with certain exceptions, for the purpose of maintaining our qualification as a REIT under the Internal Revenue Code. Such restrictions in our charter do not apply to Gary Shiffman, the Estate of Milton M. Shiffman and Robert B. Bayer, a former director and officer of the Company. The 9.8% ownership limit, as well as our ability to issue additional shares of common stock or shares of other stock (which may have rights and preferences over the common stock), may discourage a change of control of the Company and may also: (1) deter tender offers for the common stock, which offers may be advantageous to stockholders; and (2) limit the opportunity for stockholders to receive a premium for their common stock that might otherwise exist if an investor were attempting to assemble a block of common stock in excess of 9.8% of the outstanding shares of the Company or otherwise effect a change of control of the Company. Staggered Board. Our Board of Directors has been divided into three classes of directors. The term of one class will expire each year. Directors for each class will be chosen for a three-year term upon the expiration of such class's term, and the directors in the other two classes will continue in office. The staggered terms for directors may affect the stockholders' ability to change control of the Company even if a change in control were in the stockholders' interest. Preferred Stock. Our charter authorizes the Board of Directors to issue up to 10,000,000 shares of preferred stock and to establish the preferences and rights (including the right to vote and the right to convert into shares of common stock) of any shares issued. The power to issue preferred stock could have the effect of delaying or preventing a change in control of the Company even if a change in control were in the stockholders' interest. Rights Plan. We adopted a stockholders' rights plan in 1998 that provides our stockholders (other than a stockholder attempting to acquire a 15% or greater interest in the Company) with the right to purchase stock in the Company at a discount in the event any person attempts to acquire a 15% or greater interest in the Company. Because this plan could make it more expensive for a person to acquire a controlling interest in the Company, it could have the effect of delaying or preventing a change in control of the Company even if a change in control were in the stockholders' interest. Changes in our investment and financing policies may be made without stockholder approval. Our investment and financing policies, and our policies with respect to certain other activities, including our growth, debt, capitalization, distributions, REIT status, and operating policies, are determined by our Board of Directors. Although the Board of Directors has no present intention to do so, these policies may be amended or revised from time to time at the discretion of the Board of Directors without notice to or a vote of our stockholders. Accordingly, stockholders may not have control over changes in our policies and changes in our policies may not fully serve the interests of all stockholders. 15

Substantial sales of our common stock could cause our stock price to fall. Sales of a substantial number of shares of our common stock, or the perception that such sales could occur, could adversely affect prevailing market prices for shares. As of December 31, 2003, up to 3,300,000 shares of our common stock may be issued in the future to the limited partners of the Operating Partnership in exchange for their Common or Convertible Preferred OP Units. These Preferred OP Units are convertible at prices ranging from $44 to $68. The limited partners may sell such shares pursuant to registration rights or an available exemption from registration. Also, Water Oak, Ltd., a former owner of one of the Properties, will be issued Common OP Units with a value of approximately $1,000,000 annually through 2007. In 2008 and 2009, Water Oak, Ltd. will be issued Common OP Units with a value of approximately $1,200,000. In addition, as of December 31, 2003, options to purchase 810,751 shares of our common stock were outstanding under our 1993 Employee Stock Option Plan, our 1993 Non-Employee Director Stock Option Plan and our Long-Term Incentive Plan (the "Plans") and an additional 364,513 shares have been reserved for issuance pursuant to the Plans. No prediction can be made regarding the effect that future sales of shares of our common stock will have on the market price of shares. An increase in interest rates may have an adverse effect on the price of our common stock. One of the factors that may influence the price of our common stock in the public market will be the annual distributions to stockholders relative to the prevailing market price of the common stock. An increase in market interest rates may tend to make the common stock less attractive relative to other investments, which could adversely affect the market price of our common stock. 16

ITEM 2. PROPERTIES General. As of December 31, 2003, the Properties consisted of 115 manufactured housing communities, five recreational vehicle communities, and seven properties containing both manufactured housing and recreational vehicle sites located in seventeen states concentrated in the midwestern and southeastern United States. As of December 31, 2003, the Properties contained 43,875 developed sites comprised of 38,797 developed manufactured home sites and 5,078 recreational vehicle sites and an additional 6,756 manufactured home sites suitable for development. Most of the Properties include amenities oriented towards family and retirement living. Of the 127 Properties, 61 have more than 300 developed manufactured home sites, with the largest having 913 developed manufactured home sites. As of December 31, 2003, the Properties had an occupancy rate of 89.5 percent in stabilized communities and 58.7 percent in development communities and the aggregate occupancy rate was 86 percent excluding recreational vehicle sites. Since January 1, 2003, the Properties have averaged an aggregate annual turnover of homes (where the home is moved out of the community) of approximately 3.9 percent and an average annual turnover of residents (where the home is sold and remains within the community, typically without interruption of rental income) of approximately 7.4 percent. We believe that our Properties' high amenity levels contribute to low turnover and generally high occupancy rates. All of the Properties provide residents with attractive amenities with most offering a clubhouse, a swimming pool, laundry facilities and cable television service. Many Properties offer additional amenities such as sauna/whirlpool spas, tennis, shuffleboard and basketball courts and/or exercise rooms. We have tried to concentrate our communities within certain geographic areas in order to achieve economies of scale in management and operation. The Properties are principally concentrated in the midwestern and southeastern United States. We believe that geographic diversification will help insulate the portfolio from regional economic influences.

(6) The Company formerly leased this Property and the Company purchased this Property in January 2004. (7) This Property contains recreational vehicle sites. (8) Occupancy in these properties reflects the fact that these communities are newly developed from the ground up. (9) This Property is owned by an affiliate of Sunchamp LLC, an entity in which the Company owns approximately a 66 percent equity interest as of December 31, 2003. Prior to 2002, the Company held a minority interest in Sunchamp LLC and, therefore, did not treat this Property as a Property owned by the Company. As a result, the Company did not report any information in respect of this Property for such periods. 22

Leases. The typical lease we enter into with a tenant for the rental of a site is month-to-month or year-to-year, renewable upon the consent of both parties, or, in some instances, as provided by statute. In some cases, leases are for one-year terms, with up to ten renewal options exercisable by the tenant, with rent adjusted for increases in the consumer price index. These leases are cancelable for non-payment of rent, violation of community rules and regulations or other specified defaults. During the past five years, on average 3.3 percent of the homes in our communities have been removed by their owners and 7.8 percent of the homes have been sold by their owners to a new owner who then assumes rental obligations as a community resident. The small percentage of homes removed from our communities is impacted by the $3,000 to $8,000 cost to move a home. The above experience can be summarized as follows: the average resident remains in our communities for approximately nine years, while the average home, which gives rise to the rental stream, remains in our communities for approximately thirty years. See "Regulations and Insurance." ITEM 3. LEGAL PROCEEDINGS On April 9, 2003, T.J. Holdings, LLC ("TJ Holdings"), a member of Sun/Forest, LLC ("Sun/Forest") (which, in turn, owns an equity interest in SunChamp LLC), filed a complaint against the Company, SunChamp LLC, certain other affiliates of the Company and two directors of Sun Communities, Inc. in the Superior Court of Guilford County, North Carolina. The complaint alleges that the defendants wrongfully deprived the plaintiff of economic opportunities that they took for themselves in contravention of duties allegedly owed to the plaintiff and purports to claim damages of $13.0 million plus an unspecified amount for punitive damages. The Company believes the complaint and the claims threatened therein have no merit and will defend it vigorously. The Company is involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS Not applicable 23

PART II ITEM 5. MARKET FOR THE COMPANY'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS MARKET INFORMATION Our common stock has been listed on the New York Stock Exchange ("NYSE") since December 8, 1993 under the symbol "SUI." On March 1, 2004, the closing sales price of the common stock was $40.97 and the common stock was held by approximately 608 holders of record. The following table sets forth the high and low closing sales prices per share for the common stock for the periods indicated as reported by the NYSE and the distributions per share paid by the Company with respect to each such period.

On January 5, 2004 the Operating Partnership issued 47,250 Series B-3 Preferred Units to the members of Westbrook Co., Ltd, paid approximately $1.2 million in cash and assumed approximately $4.2 million of debt, which was immediately retired, in exchange for property with a net agreed upon value of $10.1 million. Holders of the Series B-3 Units may redeem the Series B-3 Units (a) within the ninety (90) day period following each of the fifth, sixth, seventh, eighth, ninth and tenth anniversaries of the issuance date, (b) in the event of the death of a holder, and (c) at any time after the tenth anniversary. The redemption price is $100 per Series B-3 Unit. The Operating Partnership has the right to redeem the Series B-3 Units at any time after the tenth anniversary. In 2003, the Company issued an aggregate of 97,416 shares of its common stock upon conversion of an aggregate of 97,416 partnership units. All of the above partnership units and shares of common stock were issued in private placements in reliance on Section 4(2) of the Securities Act of 1933, as amended, including Regulation D promulgated thereunder.

ITEM 7. 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 notes thereto elsewhere herein. The Company is a fully integrated, self-administered and self-managed REIT which owns, operates, develops and finances manufactured housing communities concentrated in the midwestern and southeastern United States. As of December 31, 2003, the Company owned and operated a portfolio of 127 developed properties located in seventeen states, including 115 manufactured housing communities, five recreational vehicle communities, and seven properties containing both manufactured housing and recreational vehicle sites. During 2003, the Company acquired one manufactured housing community located in East Lansing, Michigan, comprising 62 developed sites and 182 sites suitable for development for $4.5 million, and the Company sold four manufactured housing communities located in Michigan and Illinois which comprised 731 sites for $24.8 million. The Company has been experiencing increased vacancies due primarily to the glut of repossessed homes caused by lax credit standards in the mid to late 1990's. As lenders recognize their problems and repossess homes, the Company's vacancies rise. Industry estimates are that such conditions are abating and the number of repossessed homes in 2004 will approximate 60,000, roughly one-half of the number in recent years. This abatement should have positive effects on new home sales which fill sites in the Company's communities. CRITICAL ACCOUNTING POLICIES AND ESTIMATES Management's Discussion and Analysis of Financial Condition and Results of Operations discusses the Company's consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. In preparing these financial statements, management has made its best estimates and judgment of certain amounts included in the financial statements. Nevertheless, actual results may differ from these estimates under different assumptions or conditions. Management believes the following significant accounting policies, among others, affect its more significant judgments and estimates used in the preparation of its consolidated financial statements: Impairment of Long-Lived Assets. Rental property is recorded at cost, less accumulated depreciation. Management evaluates the recoverability of its investment in rental property whenever events or changes in circumstances, such as recent operating results, expected net operating cash flow and plans for future operations, indicate that full asset recoverability is questionable. If such assets were deemed to be impaired as a result of this measurement, the impairment that would be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset as determined on a discounted net cash flow basis. 28

Notes Receivable. The Company evaluates the recoverability of its notes receivable whenever events occur or there are changes in circumstances such that management believes it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan agreement. The loan is then measured based on the present value of the expected future cash flow discounted at the loan's effective interest rate or the fair value of the collateral if the loan is collateral dependent. Depreciation. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets. The Company uses a thirty year useful life for land improvements and buildings and a seven to fifteen year useful life for furniture, fixtures and equipment. Revenue Recognition. Rental income attributable to leases is recorded on a straight-line basis when earned from tenants. Leases entered into by tenants generally range from month-to-month to one year and are renewable by mutual agreement of the Company and the resident. Capitalized Costs. The Company capitalizes certain costs (including interest and other costs) incurred in connection with the development, redevelopment, capital enhancement and leasing of its properties. Management is required to use professional judgment in determining whether such costs meet the criteria for immediate expense or capitalization. The amounts are dependent on the volume and timing of such activities and the costs associated with such activities. Maintenance, repairs and minor improvements to properties are expensed when incurred. Renovations and improvements to properties are capitalized and depreciated over their estimated useful lives and construction costs related to the development of new community or expansion sites are capitalized until the property is substantially complete. Certain expenditures to dealers and residents related to obtaining lessees in our communities are capitalized and amortized over a seven year period; shorter than the average resident's occupancy in the home and the average term that the home is in our community. Costs associated with implementing the Company's new computer systems are capitalized and amortized over the estimated useful lives of the related software and hardware. Derivative Instruments and Hedging Activities. The Company has entered into three interest rate swap agreements to offset interest rate risk. The Company does not enter into derivative transactions for speculative purposes. The Company adjusts its balance sheet on an ongoing quarterly basis to reflect current fair market value of its derivatives. Changes in the fair value of derivatives are recorded each period in earnings or comprehensive income, as appropriate. The ineffective portion of the hedge is immediately recognized in earnings to the extent that the change in value of a derivative does not perfectly offset the change in value of the instrument being hedged. The unrealized gains and losses held in accumulated other comprehensive income will be reclassified to earnings over time and occurs when the hedged items are also recognized in earnings. The Company uses standard market conventions to determine the fair values of derivative instruments, including the quoted market prices or quotes from brokers or dealers for the same or similar instruments. All methods of assessing fair value result in a general approximation of value and such value may never actually be realized. Deferred Tax Assets. SHS currently has significant deferred tax assets, which are subject to periodic recoverability assessments. SHS has recognized deferred tax assets of $2.0 million, net of a valuation reserve of $3.0 million. Realization of these deferred tax assets is principally dependent upon SHS's achievement of expected future taxable income. Judgments regarding future profitability may change due to future market conditions, SHS's ability to continue to successfully execute its business plan, and other factors. 29

Income Taxes. The Company has elected to be taxed as a REIT as defined under Section 856(c) of the Internal Revenue Code of 1986, as amended. In order for the Company to qualify as a REIT, at least ninety-five percent (95%) of the Company's gross income in any year must be derived from qualifying sources. As a REIT, the Company generally will not be subject to U.S. Federal income taxes at the corporate level if it distributes at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders, which it fully intends to do. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to Federal income tax (including any applicable alternative minimum tax) on its taxable income at regular corporate rates. The Company remains subject to certain state and local taxes on its income and property as well as Federal income and excise taxes on its undistributed income. RESULTS OF OPERATIONS Comparison of year ended December 31, 2003 to year ended December 31, 2002 For the year ended December 31, 2003, income from operations increased by $3.8 million from $21.6 million to $25.4 million, when compared to the year ended December 31, 2002. The increase was due to increased revenues of $29.0 million and increased results from affiliates of $17.3 million partially offset by increased expenses of $42.5 million. The year 2003 included SHS on a consolidated basis as discussed below. Income from rental property increased by $9.2 million from $149.9 million to $159.1 million, or 6.2 percent, due to rent increases and other community revenues ($3.4 million) and acquisitions ($5.8 million). Interest income increased by $3.4 million from $8.0 million to $11.4 million, or 42.1 percent, due principally to larger outstanding balances of notes and investments at higher rates of interest. Other operating income decreased by $6.6 million from $2.3 million to ($4.3) million, due primarily to reduced development fee income and a $4.9 million write down of an impaired asset. The remaining revenue increases of $22.9 million relate to the consolidation of Sun Home Services which is discussed in detail below. Property operating and maintenance expenses increased by $6.1 million from $33.7 million to $39.8 million, or 18.0 percent. The increase was primarily due to increases in utility costs ($1.8 million) and increases in repair and maintenance expenses ($1.3 million). Acquisitions during 2002 and the consolidation of SunChamp properties accounted for the remaining increase of $3.0 million. Real estate taxes increased by $1.5 million from $10.2 million to $11.7 million, or 15.0 percent due to acquisitions made in 2002 ($0.7 million) and increases in assessments and tax rate ($0.8 million). Selling, general, and administrative expenses increased by $10.4 million from $7.7 million to $18.1 million, due to the consolidation of Sun Home Services ($7.6 million), professional fees ($0.4 million), expenses related to office relocation ($0.2 million), Michigan Single Business tax ($0.2 million), compensation expenses, including benefits, primarily related 30

to the SunChamp acquisition and a systems conversion ($1.7 million), and assorted other minor increases ($0.3 million). Depreciation and amortization increased by $6.2 million from $37.9 million to $44.1 million, or 16.4 percent, due primarily to the consolidation of Sun Home Services ($1.0 million) and additional investment in rental property. Interest expense increased by $4.3 million from $32.4 million to $36.7 million, or 13.3 percent, due to increased debt levels partially offset by lower interest rates ($1.5 million), decreased capitalized interest ($0.8 million), an increase in financing costs ($0.6 million), and an increase in interest rates related to fixing rates on $75.0 million of debt ($2.7 million). These increases were partially offset by $1.3 million of income related primarily to the change in market value of an interest rate swap contract that does not qualify for hedge accounting. Equity income from affiliates of $0.7 million represents the Company's one-third interest in the operations of Origen for its initial operating period after a recapitalization in October, 2003. The remaining expense increase of $13.9 million relates to the consolidation of Sun Home Services which is discussed in detail below. Sun Home Services Prior to January 1, 2003, the results of operations of Sun Home Services were accounted for using the equity method and reported as a single line item called equity in income from affiliates. As the Company is the primary beneficiary of the results of operations of Sun Home Services, it is appropriate to consolidate Sun Home Services at December 31, 2003. This has no effect on previously reported net income. The following table summarizes certain financial and statistical data for Sun Home Services for the years ended December 31, 2003 and 2002: INCREASE/ 2003 2002 (DECREASE) PERCENT CHANGE --------- ---------- --------- -------------- (Pro Forma) New home sales revenues $13,169 $15,890 $(2,721) (17.1%) Cost of sales 9,159 12,907 (3,748) (29.0%) ------- ------- ------- ----- Gross profit 4,010 2,983 1,027 34.4% ======= ======= ======= ===== Pre-owned home sales revenues $ 6,347 $ 3,214 $ 3,133 97.5% Cost of sales 4,720 2,586 2,134 82.5% ------- ------- ------- ----- Gross profit 1,627 628 999 159.1% ======= ======= ======= ===== Ancillary revenue, net $ 3,409 $ 1,519 $ 1,890 124.4% ======= ======= ======= ===== Home sales volumes: New homes 257 286 (29) (10.1%) Pre-owned homes 283 174 109 62.6% New home sales declined by 10.1 percent, while revenues and costs of sales declined by 31

17.1 and 29.0 percent, respectively. Gross profit increased by 34.4 percent as cost of sales declined by more than revenues due to the purchase of new homes at a substantial discount. Pre-owned home unit sales increased by 62.6 percent while revenues and cost of sales increased by 97.5 percent and 82.5 percent, respectively. Gross profit increased by 159.1 percent as revenues grew more than cost of sales due to strong demand for the value in pre-owned homes. The increase in ancillary revenue, net, is primarily due to increased activity in the Company's rental home program. Comparison of year ended December 31, 2002 to year ended December 31, 2001 For the year ended December 31, 2002, income from operations decreased by $20.0 million from $41.6 million to $21.6 million, when compared to the year ended December 31, 2001. The decrease was due to increased expenses of $12.5 million, increased revenues of $9.2 million and increased loss from affiliates of $16.7 million as described in more detail below. Income from rental property increased by $12.9 million from $137.0 million to $149.9 million, or 9.4 percent, due to rent increases and other community revenues ($5.9 million) and acquisitions ($7.0 million). Interest income decreased by $2.3 million from $10.3 million to $8.0 million, or 22.5 percent, due primarily to a decrease in interest earning notes and receivables. Other income decreased by $1.4 million from $3.7 million to $2.3 million, or 37.8 percent, due primarily to reduced development fee income. Property operating and maintenance expenses increased by $4.4 million from $29.3 million to $33.7 million, or 15.0 percent, due to acquired communities ($1.9 million) and increases in costs including payroll ($1.2 million), workers' compensation ($0.5 million), and cable television ($0.3 million), and other expenses ($0.5 million). Real estate taxes increased by $1.0 million from $9.2 million to $10.2 million, or 11.5 percent due to acquired communities ($0.5 million) and changes in certain assessments. General and administrative expenses increased by $0.3 million from $7.4 million to $7.7 million, representing 4.8 percent and 4.9 percent of total revenues in 2002 and 2001, respectively. Depreciation and amortization increased by $5.2 million from $32.7 million to $37.9 million, due primarily to the net additional investments in rental properties. Interest expense increased by $1.4 million from $31.0 million to $32.4 million due primarily to financing additional investments in rental property ($6.0 million), offset by decreasing rates on variable rate debt ($4.9 million). Equity loss from affiliates increased by $16.7 million from income of $0.1 million to a loss of $16.6 million primarily due to equity losses at SHS ($0.7 million), SunChamp ($0.4 million) and Origen ($1.7 million) and the valuation adjustment of the Company's investment in Origen ($13.6 million) and a technology investment ($0.3 million). 32

SAME PROPERTY INFORMATION The following table reflects property-level financial information as of and for the years ended December 31, 2003 and 2002. The "Same Property" data represents information regarding the operation of communities owned as of January 1, 2002 and December 31, 2003. Site, occupancy, and rent data for those communities is presented as of the last day of each period presented. The "Total Portfolio" column differentiates from the "Same Property" column by including financial information for properties acquired after January 1, 2002 and new development communities.

(2) Investors in and analysts following the real estate industry utilize net operating income ("NOI") as a supplemental performance measure. The Company considers NOI, given its wide use by and relevance to investors and analysts, an appropriate supplemental measure to net income because NOI provides a measure of rental operations and does not factor in depreciation/amortization and non-property specific expenses such as general and administrative expenses. (3) Same property information does not include properties sold during the year ended December 31, 2003. On a same property basis, property net operating income increased by $0.6 million from $97.3 million to $97.9 million, or 0.6 percent. Income from property increased by $3.1 million from $132.1 million to $135.2 million, or 2.3 percent, due primarily to increases in rents including water and property tax pass through. Property operating expenses increased by $1.8 million from $24.9 million to $26.7 million, or 7.2 percent, due to increases in real estate taxes ($0.7 million), repair and maintenance ($0.9 million), and payroll ($0.2 million). 33

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 Operating Partnership's unitholders, property acquisitions, development and expansion of properties, capital improvements of properties and debt repayment. The Company expects to meet its short-term liquidity requirements through its working capital provided by operating activities and its line of credit, as described below. The Company considers its ability to generate cash from operations (anticipated to be approximately $70 million) to be adequate to meet all operating requirements, including recurring capital improvements, routinely amortizing debt and other normally recurring expenditures of a capital nature, pay dividends to its stockholders to maintain qualification as a REIT in accordance with the Internal Revenue Code and make distributions to the Operating Partnership's unitholders. The Company plans to invest approximately $5.0 million in developments consisting of expansions to existing communities and the continuing development of new communities. 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 expects to invest in the range of $20.0 to $40.0 million in the acquisition of individual properties in 2004, depending upon market conditions. The Company plans to finance these investments by using net cash flows provided by operating activities and by drawing upon its line of credit. Cash and cash equivalents increased by $21.4 million to $24.1 million at December 31, 2003 compared to $2.7 million at December 31, 2002 due to the net proceeds received from the sale of four properties. Net cash provided by operating activities increased by $12.3 million to $63.3 million for the year ended December 31, 2003 compared to $51.0 million for the year ended December 31, 2002. The increase resulted primarily from increased net income, higher depreciation, the effect of consolidating SHS, and changes in other miscellaneous asset and liabilities accounts. 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 markets; (b) lower occupancy rates of 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 October 2003, the Company acquired a community in East Lansing, MI and financed the acquisition with a mortgage for $2.3 million and the remainder in cash. The Company entered into a $25 million loan facility in September of 2003, of which $25 million was available to be borrowed at December 31, 2003. Borrowings bear an interest rate of Federal Funds Effective Rate plus .85% and mature on March 24, 2004. In April 2003 the Company issued $150 million of 5.75 percent senior notes, due April 15, 2010, and used the proceeds from the offering to retire the bridge loan of $48 million and senior notes of $85 million which matured on April 30 and May 1, 2003, respectively. The remaining proceeds paid down the Company's line of credit. 34

The Company has a $105 million unsecured line of credit facility, which matures in July 2005, with a one-year optional extension. At December 31, 2003, the average interest rate of outstanding borrowings under the line of credit was 2.05%, $99 million was outstanding and $6 million was available to be drawn under the facility. The line of credit facility contains various leverage, debt service coverage, net worth maintenance and other customary covenants all of which the Company was in compliance with at December 31, 2003. The Company's primary long-term liquidity needs are principal payments on outstanding indebtedness. At December 31, 2003, the Company's outstanding contractual obligations were as follows: PAYMENTS DUE BY PERIOD (IN THOUSANDS) -------------------------------------------------------------- CONTRACTUAL CASH OBLIGATIONS TOTAL DUE 1 YEAR 2-3 YEARS 4-5 YEARS AFTER 5 YEARS ---------- --------- --------------- --------- ------------- Line of credit $ 99,000 $ - $ 99,000 $ - $ - Collateralized term loan 41,547 706 1,569 39,272 - Collateralized term loan - FNMA 152,363 - - - 152,363 Senior notes (1) 350,000 - 65,000 135,000 150,000 Mortgage notes, other 62,664 24,823 12,276 8,008 17,557 Capitalized lease obligations 9,606 9,606 - - - Redeemable Preferred OP Units 58,148 - 8,176 4,500 45,472 -------- -------- -------- -------- -------- $773,328 $ 35,135 $186,021 $186,780 $365,392 ======== ======== ======== ======== ======== (1) The provisions of the callable/redeemable $65 million notes are such that the maturity date will likely be 2005 if the 10-year treasury rate is greater than 5.7% on May 16, 2005. The maturity is reflected in the above table based on that assumption. The Company anticipates meeting its long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions and Operating Partnership unit redemptions, through the issuance of debt or equity securities, including equity units in the Operating Partnership, or from selective asset sales. Since 1993, the Company has raised, in the aggregate, nearly $1 billion from the sale of shares of its common stock, from the sale of OP units in the Operating Partnership, and the issuance of secured and unsecured debt securities. In addition, at December 31, 2003, 92 of the Properties were unencumbered by debt, therefore, providing substantial financial flexibility. 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". If the Company is unable to obtain additional equity or debt financing on acceptable terms, the Company's business, results of operations and financial condition will be harmed. 35

Included in debt are $35.8 million of Preferred OP Units which would require collateralization were the Company to no longer be classified as investment grade by the rating agencies. At December 31, 2003, the Company's debt to total market capitalization approximated 46.0 percent (assuming conversion of all Common OP Units to shares of common stock). The debt has a weighted average maturity of approximately 5.2 years and a weighted average interest rate of 5.4 percent. Capital expenditures for the years ended December 31, 2003 and 2002 included recurring capital expenditures of $6.5 million (excluding $1.7 million related to a main office relocation and $3.4 million related to a software conversion) and $7.1 million, respectively. Net cash used in investing activities was $58.9 million for the year ended December 31, 2003 compared to $168.9 million in the prior year. The differences are due to: decreased investment in rental properties of $37.0 million; increased proceeds from property disposition of $19.3 million; increased repayments of notes receivables of $49.5 million; and decreased investment in and advances to affiliates of $4.2 million. Included in proceeds from property dispositions is $22.5 million of proceeds deposited with an intermediary for Section 1031 exchange purposes. These sales proceeds will be disbursed as the Company exchanges properties under Section 1031 of the Internal Revenue Code. Net cash provided by financing activities was $17.0 million for the year ended December 31, 2003, compared to $116.0 million in the prior year. The differences were primarily due to changes in net proceeds from notes payable, inclusive of borrowings on line of credit, of $109.6 million, increased distributions of $2.4 million, offset by changes in net proceeds from common stock issuance of $12.4 million and changes in payments of deferred financing costs of $0.6 million. RATIO OF EARNINGS TO FIXED CHARGES The Company's ratio of earnings to fixed charges for the years ended December 31, 2003, 2002, and 2001 was 1.29:1, 1.68:1 and 1.73:1 respectively. INFLATION Most of the leases allow for periodic rent increases which provide the Company with the opportunity to achieve increases in rental income as each lease expires. Such types of leases generally minimize the risk of inflation to the Company. 36

These forward-looking statements reflect the Company's current views with respect to future events and financial performance, but involve known and unknown risks and uncertainties, both general and specific to the matters discussed in this press release. These risks and uncertainties may cause the actual results of the Company to be materially different from any future results expressed or implied by such forward looking statements.

The forward-looking statements contained in this Form 10-K speak only as of the date hereof and the Company expressly disclaims any obligation to provide public updates, revisions or amendments to any forward-looking statements made herein to reflect changes in the Company's expectations of future events. RECENT ACCOUNTING PRONOUNCEMENTS In May 2003, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity" which establishes standards for how financial instruments that have characteristics of both liabilities and equity instruments should be classified on the balance sheet. The requirements of SFAS 150 generally outline that financial instruments that give the issuer a choice of settling an obligation with a variable number of securities or settling an obligation with a transfer of assets or any mandatorily redeemable security should be classified as a liability on the balance sheet. The Company has reclassified mandatorily redeemable preferred operating partnership units of $58.1 million into debt as of December 31, 2003. The reclassification had no effect on the Company's compliance with the covenant requirements of its credit agreements. In April 2003, FASB issued SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." The statement amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities under FASB Statements No. 133, "Accounting for Derivative Instruments and Hedging Activities." This Statement is effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. In addition, all provisions of this Statement should be applied prospectively. The provisions of this Statement that relate to Statement 133 Implementation Issues that have been effective for fiscal quarters that began prior to June 15, 2003, should continue to be applied in accordance with their respective effective dates. The adoption of this Statement did not have a significant impact on the financial position or results of the operations of the Company. 37

In January 2003, the FASB issued FASB Interpretation No. 46 ("FIN 46"), "Consolidation of Variable Interest Entities." The objective of this interpretation is to provide guidance on how to identify a variable interest entity ("VIE") and determine when the assets, liabilities, non-controlling interests and results of operations of a VIE need to be included in a company's consolidated financial statements. A company that holds variable interests in an entity will need to consolidate the entity if the company's interest in the VIE is such that the company will absorb a majority of the VIE's expected losses and/or receive a majority of the VIE's expected residual returns, if they occur. FIN 46 also requires additional disclosures by primary beneficiaries and other significant variable interest holders. The provisions of this interpretation apply to the end of the first interim period or annual period ending after December 15, 2003 (i.e., December 31, 2003) to VIEs in which a company holds a variable interest that it acquired before February 1, 2003. The Company has consolidated SHS in its financial reporting beginning December 31, 2003. OTHER 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 property, plus rental property depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures." Industry analysts consider FFO to be an appropriate supplemental measure of the operating performance of an equity REIT primarily because the computation of FFO excludes historical cost depreciation as an expense and thereby facilitates the comparison of REITs which have different cost bases in their assets. Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time, whereas real estate values have instead historically risen or fallen based upon market conditions. FFO does not represent cash flow from operations as defined by generally accepted accounting principles and is a supplemental measure of performance that does not replace net income as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, FFO is not intended as a measure of a REIT's ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. The following table reconciles net income to FFO and calculates FFO data for both basic and diluted purposes for the years ended December 31, 2003, 2002, 2001 (in thousands): 38

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 are excluded from Funds from Operations. 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 Funds from Operations. At December 31, 2003, the remaining balance on the SunChamp note is approximately $0.3 million. 39

ITEM 7A. 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 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 4.93 percent for the period April 2003 through July 2009, another of the 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. The Company's remaining variable rate debt totals $196.6 million as of December 31, 2003 which bears interest at various LIBOR or FNMA Discounted Mortgage Backed Securities ("DMBS") rates. If LIBOR or DMBS increased or decreased by 1.0 percent during the years ended December 31, 2003 and 2002, the Company believes its interest expense would have increased or decreased by approximately $2.2 million and $1.7 million, respectively, based on the $215.3 million and $171.3 million average balance outstanding under the Company's variable rate debt facilities for the year ended December 31, 2003 and 2002, respectively. Additionally, the Company had $32.1 million and $27.3 million LIBOR based variable rate mortgage and other notes receivable as of December 31, 2003 and 2002. If LIBOR increased or decreased by 1.0 percent during the years ended December 31, 2003 and 2002, the Company believes interest income would have increased or decreased by approximately $0.30 million and $0.37 million, respectively, based on the $30.2 million and $36.7 million average balance outstanding on all variable rate notes receivable for the year ended December 31, 2003 and 2002, respectively.

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: a. BUSINESS: Sun Communities, Inc. (the "Company") is a real estate investment trust ("REIT") which owns and operates 127 manufactured housing communities at December 31, 2003 located in seventeen states concentrated principally in the Midwest and Southeast comprising approximately 43,875 developed sites and approximately 6,756 sites suitable for development. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. b. PRINCIPLES OF CONSOLIDATION: The accompanying financial statements include the accounts of the Company and all majority-owned and controlled subsidiaries including Sun Communities Operating Limited Partnership (the "Operating Partnership") SunChamp LLC ("SunChamp"), and effective December 31, 2003, Sun Home Services, Inc. ("SHS"). SHS is consolidated beginning in 2003 in accordance with Financial Interpretation No. 46, "Consolidation of Variable Interest Entities" as further described in Note 13. The minority interests include Common Operating Partnership Units ("OP Units") which are convertible into an equivalent number of shares of the Company's common stock. Such conversion would have no effect on earnings per share since the allocation of earnings to an OP Unit is equivalent to earnings allocated to a share of common stock. Of the 21.5 million OP Units outstanding at December 31, 2003, the Company owns 19.0 million or 88.5 percent. The minority interests are adjusted to their relative ownership interest whenever OP Units or common stock are issued, converted or retired by reclassification to/from paid-in capital. Included in minority interests at December 31, 2003 and 2002 are 2 million Series A Perpetual Preferred OP Units ("PPOP Units") issued at $25 per unit in September 1999 bearing an annual coupon rate of 8.875 percent. The PPOP Units may be called under certain conditions by the Company at par on or after September 29, 2004, have no stated maturity or mandatory redemption and are convertible into preferred stock under certain circumstances. $58.1 million of Preferred OP Units ("POP Units") are included in debt at December 31, 2003 with dividends at rates ranging from 6.0 percent to 7.6 percent and maturing between 2006 and 2014. Of these POP Units, $43.8 million have conversion prices ranging from $44 to $68 per unit. Of the $58.1 million POP Units included in debt, $4.2 million were issued during 2003 in connection with property acquisitions. These POP Units pay dividends at 7.625% and mature on May 15, 2010.

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED: c. RENTAL PROPERTY: Rental property is recorded at cost, less accumulated depreciation. Management evaluates the recoverability of its investment in rental property whenever events or changes in circumstances such as recent operating results, expected net operating cash flow and plans for future operations indicate that full asset recoverability is questionable. The Company measures the recoverability of its assets in accordance with the Statement of Financial Accounting Standards No. 144 ("SFAS 144"), "Accounting for the Impairment or Disposal of Long Lived Assets." If such assets were deemed to be impaired as a result of this measurement, the impairment that would be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset as determined on a discounted net cash flow basis. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets. Useful lives are 30 years for land improvements and buildings and 7 to 15 years for furniture, fixtures and equipment. Expenditures for ordinary maintenance and repairs are charged to operations as incurred and significant renovations and improvements, which improve and/or extend the useful life of the asset, are capitalized and depreciated over their estimated useful lives. Construction costs related to development of new communities or expansion sites, including interest, are capitalized until the property is substantially complete. The Company capitalizes certain costs (including interest and other costs) incurred in connection with the development, redevelopment, capital enhancement and leasing of its properties. Management is required to use professional judgment in determining whether such costs meet the criteria for immediate expense or capitalization. The amounts are dependent on the volume and timing of such activities and the costs associated with such activities. d. CASH AND CASH EQUIVALENTS: The Company considers all highly liquid investments with an initial maturity of three months or less to be cash and cash equivalents. e. NOTES AND ACCOUNTS RECEIVABLE: The Company evaluates the recoverability of its receivables whenever events occur or there are changes in circumstances such that management believes it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan and lease agreements. The collectibility of loans is measured based on the present value of the expected future cash flow discounted at the loan's effective interest rate or the fair value of the collateral if the loan is collateral dependent. The reserve for uncollectible accounts receivable from residents was $0.15 million at December 31, 2003 and 2002. F-10

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED: f. INVESTMENTS IN AND ADVANCES TO AFFILIATES: Origen Financial, Inc. ("Origen, Inc") 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 (representing approximately 33% of the issued and outstanding shares of common stock as of December 31, 2003) of Origen, Inc. for $50 million and agreed to sell Origen, Inc. various interests in manufactured home loans. The Company's investment in Origen, Inc. was accounted for using the equity method of accounting for periods ending after September 30, 2003. During 2002 and through October 7, 2003, the Company, through SHS, and two other participants (one unaffiliated and one affiliated with Gary Shiffman, the Company's Chief Executive Officer and President) provided financing to Origen Financial, L.L.C. ("Origen"), the predecessor to Origen Inc. The financing consisted of a $48 million line of credit and a $10 million term loan of which $35 million was outstanding at September 30, 2003. This amount was repaid in full in October 2003 upon the formation and capitalization of Origen, Inc. Summarized combined financial information of the Company's equity investment in Origen, Inc. at December 31, 2003 and Origen and SHS at December 31, 2002 is presented below before elimination of intercompany transactions. SHS and SunChamp are consolidated in the Company's financial statements as of December 31, 2003.

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED: g. REVENUE RECOGNITION: Rental income attributable to leases is recorded on a straight-line basis when earned from tenants. Leases entered into by tenants generally range from month-to-month to one year and are renewable by mutual agreement of the Company and resident or, in some cases, as provided by state statute. Revenue from the sale of manufactured homes is recognized upon transfer of title at the closing of the sales transaction. h. OTHER CAPITALIZED COSTS: Certain expenditures to dealers and residents related to obtaining lessees in our communities are capitalized and amortized over a seven year period; shorter than average resident's occupancy and the average term that the home is in the community. Costs associated with implementing the Company's new computer systems are capitalized and amortized over the estimated useful lives of the related software and hardware. i. FAIR VALUE OF FINANCIAL INSTRUMENTS: The carrying values of cash and cash equivalents, escrows, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the shorter maturities of these instruments. The fair value of the Company's long-term indebtedness, which is based on the estimates of management and on rates currently quoted and rates currently prevailing for comparable loans and instruments of comparable maturities, exceeds the aggregate carrying value by approximately $28.0 million at December 31, 2003. Potential expenses that would be incurred in an actual sale or settlement are not taken into consideration. j. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: The Company has entered into four derivative contracts consisting of three interest rate swap agreements and an interest rate cap agreement. The Company's primary strategy in entering into derivative contracts is to minimize the variability that changes in interest rates could have on its future cash flows. The Company generally employs derivative instruments that effectively convert a portion of its variable rate debt to fixed rate debt and to cap the maximum interest rate on its variable rate borrowings. The Company does not enter into derivative instruments for speculative purposes. The swap agreements were effective April 2003, and have the effect of fixing interest rates relative to a collateralized term loan due to FNMA. One swap matures in July 2009, with an effective fixed rate of 4.93 percent. A second swap matures in July 2012, with an effective fixed rate of 5.37 percent. The third swap matures in July 2007, with an effective fixed rate of 3.97 percent. The third swap is effective as long as 90-day LIBOR is 7 percent or lower. The three swaps have an aggregate notional amount of $75.0 million. The interest rate cap agreement has a cap rate of 9.49 percent, a notional amount of $152.4 million and a termination date of April 03, 2006. Each of the Company's derivative contracts is based upon 90-day LIBOR. The Company has designated the first two swaps and the interest rate cap as cash flow hedges for accounting purposes. 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 twelve month period ended December 31, 2003 totals a positive $0.9 million. F-12

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED: j. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES, CONTINUED: In accordance with SFAS No. 133, the "Accounting for Derivative Instruments and Hedging Activities," which requires all derivative instruments to be carried at fair value on the balance sheet, the Company has recorded a liability of $0.9 and $2.3 million as of December 31, 2003 and December 31, 2002, 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. k. DEFERRED TAX ASSETS: The Company has certain subsidiaries that are taxed as regular corporations. Deferred tax assets or liabilities are recognized for temporary differences between the tax bases of non-REIT assets and liabilities and their carrying amounts in the financial statements and net operating loss carryforwards. Deferred tax assets and liabilities are measured using currently enacted tax rates. A valuation allowance is established if based on the insight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. l. STOCK OPTIONS: The Company accounts for its stock options using the intrinsic value method contained in APB Opinion No. 25. "Accounting for Stock Issued to Employees." If the Company had accounted for awards 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 years ended December 31, 2003, 2002 and 2001 (amounts in thousands, except for per share data): 2003 2002 2001 ---- ---- ---- Net income, as reported $ 23,714 $ 13,592 $ 33,910 Stock-based compensation expense under fair value method (274) (478) (321) -------- -------- -------- Pro forma net income $ 23,440 $ 13,114 $ 33,589 ======== ======== ======== EPS (Basic), as reported $ 1.30 $ 0.77 $ 1.96 ======== ======== ======== EPS (Basic), pro forma $ 1.29 $ 0.75 $ 1.95 ======== ======== ======== EPS (Diluted), as reported $ 1.29 $ 0.76 $ 1.94 ======== ======== ======== EPS (Diluted), pro forma $ 1.28 $ 0.74 $ 1.93 ======== ======== ======== m.

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 10. INCOME TAXES (AMOUNTS IN THOUSANDS), CONTINUED: Company's control. In addition, frequent changes occur in the area of REIT taxation, which require the Company continually to monitor its tax status. As a REIT, the Company generally will not be subject to U.S. Federal income taxes at the corporate level on the ordinary taxable income it distributes to its stockholders as dividends. If the Company fails to qualify as a REIT in any taxable year, its taxable income will be subject to U.S. Federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if the Company qualifies as a REIT, it may be subject to certain state and local income taxes and to U.S. Federal income and excise taxes on its undistributed income.

Deferred taxes reflect the estimated future tax effect of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. SHS has net operating loss carryforwards of approximately $14.7 million at December 31, 2003. A deferred asset of approximately $2.0 million, principally related to the net operating loss carryforwards, exclusive of losses related to SHS's investment in Origen, is included in other assets in the consolidated balance sheet as of December 31, 2003. The deferred tax asset at December 31, 2003 is net of a valuation allowance of $3.0 million related to SHS's net operating losses on its investment in Origen. SHS's losses will begin to expire in 2011 through 2022 if not offset by future taxable income. Management believes its deferred tax asset will be realized but realization is continuously subject to an assessment as to recoverability in the future. F-22

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 13. RECENT ACCOUNTING PRONOUNCEMENTS: In May 2003, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity" which establishes standards for how financial instruments that have characteristics of both liabilities and equity instruments should be classified on the balance sheet. The requirements of SFAS 150 generally outline that financial instruments that give the issuer a choice of settling an obligation with a variable number of securities or settling an obligation with a transfer of assets or any mandatorily redeemable security should be classified as a liability on the balance sheet. The Company has reclassified mandatorily redeemable preferred operating partnership units of $58.1 million into debt as of December 31, 2003. The reclassification had no effect on the Company's compliance with the covenant requirements of its credit agreements. In April 2003, FASB issued SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." The statement amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities under FASB Statements No. 133, "Accounting for Derivative Instruments and Hedging Activities." This Statement is effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. In addition, all provisions of this Statement should be applied prospectively. The provisions of this Statement that relate to Statement 133 Implementation Issues that have been effective for fiscal quarters that began prior to June 15, 2003, should continue to be applied in accordance with their respective effective dates. The adoption of this Statement did not have a significant impact on the financial position or results of the operations of the Company. In January 2003, the FASB issued FASB Interpretation No. 46 ("FIN 46"), "Consolidation of Variable Interest Entities." The objective of this interpretation is to provide guidance on how to identify a variable interest entity ("VIE") and determine when the assets, liabilities, non-controlling interests and results of operations of a VIE need to be included in a company's consolidated financial statements. A company that holds variable interests in an entity will need to consolidate the entity if the company's interest in the VIE is such that the company will absorb a majority of the VIE's expected losses and/or receive a majority of the VIE's expected residual returns, if they occur. FIN 46 also requires additional disclosures by primary beneficiaries and other significant variable interest holders. The provisions of this interpretation apply to the end of the first interim period or annual period ending after December 15, 2003 (i.e., December 31, 2003) to VIEs in which a company holds a variable interest that it acquired before February 1, 2003. The Company consolidated SHS in its financial reporting beginning December 31, 2003. The consolidation did not have a significant impact on the financial condition or results of operations of the Company. F-25

SUN COMMUNITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2003, 2002 AND 2001 14. CONTINGENCIES: On April 9, 2003, T.J. Holdings, LLC ("TJ Holdings"), a member of Sun/Forest, LLC ("Sun/Forest") (which, in turn, owns an equity interest in SunChamp LLC), filed a complaint against the Company, SunChamp LLC, certain other affiliates of the Company and two directors of Sun Communities, Inc. in the Superior Court of Guilford County, North Carolina. The complaint alleges that the defendants wrongfully deprived the plaintiff of economic opportunities that they took for themselves in contravention of duties allegedly owed to the plaintiff and purports to claim damages of $13.0 million plus an unspecified amount for punitive damages. The Company believes the complaint and the claims threatened therein have no merit and will defend it vigorously. The Company is involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition. 15. RELATED PARTY TRANSACTIONS: The Company and its affiliates have entered into the following transactions with Origen Inc. and its predecessor, Origen during 2002 and 2003: - Capital Investment in Origen, Inc. As described in Note 1, the Company acquired 5,000,000 shares of common stock in Origen Inc. in a private placement transaction at $10 per share. - Loan Servicing Agreement. Origen Servicing, Inc., a wholly-owned subsidiary of Origen, services approximately $23.0 million in manufactured home loans for SHS as of December 31, 2003. Sun Home Services pays Origen Servicing, Inc. an annual servicing fee of 1.25 percent of the outstanding principal balance of the loans. - Guaranty of Licensing Bonds. The Company has guaranteed Origen Inc.'s obligations to an insurance company in connection with the issuance of bonds and undertakings required by various state licensing authorities as a condition to the issuance of Origen Inc. licenses. The Company's aggregate potential obligations under these bonds is approximately $5.0 million. In addition to the transactions with Origen Inc. described above, Mr. Shiffman and his affiliates have entered into the following transactions with the Company: - Related Party Lease. The Company leases its executive offices in Southfield, Michigan from an entity in which Mr. Shiffman and certain of his affiliates beneficially own approximately a 21 percent interest. - Capital Investment in Origen Financial, Inc. As part of the Origen Inc. private placement, Shiffman Origen LLC (100 percent of which is owned by the Estate of Milton M. Shiffman, Mr. Shiffman and members of his family), acquired 1,025,000 shares of common stock of Origen Inc. at $10 per share. F-26

15. RELATED PARTY TRANSACTIONS, CONTINUED: - Ownership of SHS. Gary Shiffman, and the Estate of Milton M. Shiffman (former Chairman of the Board), are the owners of all of the outstanding common stock of SHS, and as such are entitled to 5% of the cash flow from the operating activities of SHS. - Tax Consequences Upon Sale of Properties. Gary Shiffman holds limited partnership interests in the Operating Partnership which were received in connection with the contribution of 24 properties from partnerships previously affiliated with him (the "Sun Partnerships"). Prior to any redemption of these limited partnership interests for the Company's common stock, Mr. Shiffman will have tax consequences different from those of the Company and the Company's public stockholders on the sale of any of the Sun Partnerships. Four of the properties have been sold to date. 16. SUBSEQUENT EVENTS: In February, 2004, the Company entered into an agreement with certain affiliates of Property Asset Management Inc. ("PAMI") to acquire all of the equity interests in partnerships that directly and indirectly own and operate 19 properties and entered into a real estate purchase agreement to acquire 7 other properties. The properties are recreational vehicle communities, some of which include manufactured home sites. The portfolio consists of 11,331 sites, including 10,586 developed sites and 745 expansion recreational vehicle sites. Completion of the purchases is subject to customary closing conditions. PAMI, the seller under the purchase agreements, is the sole general partner and owns a substantial majority of the equity interests in the partnerships that own the properties subject to the purchase agreements. PAMI has exercised its rights under the relevant partnership agreements to acquire the equity interests of its minority partner. PAMI has informed us that its minority partner has disputed PAMI's rights to purchase its interests under the partnership agreements. As a result, PAMI has filed suit in the Delaware Chancery Court requesting, among other things, that the court specifically enforce PAMI's right to purchase the minority interests. The minority partner in the partnerships has filed an answer and counterclaim in the case requesting that the court find that the minority partner has the right to buy PAMI's interests under the partnership agreements. PAMI believes that it will be successful in the litigation and we expect to complete the acquisition of the partnership interests and properties. However, due to the uncertain nature of litigation and the other conditions to closing, we can provide no assurance that we will be able to successfully complete the proposed acquisitions and cannot reliably predict the timing of the resolution of these matters.
