Business. --------- Forward Looking Statements -------------------------- When used within this document, the words "expects," "believes," "anticipates," "should," "estimates," and similar expressions are intended to identify "forward-looking statements". Such forward-looking statements involve known and unknown risks, uncertainties, and other factors, which may cause the actual results and performance of the Partnership to be materially different from those expressed or implied in the forward looking statements. Such factors include the impact of competition from new and existing real estate facilities which could impact rents and occupancy levels at the real estate facilities that the Partnership has an interest in; the Partnership's ability to effectively compete in the markets that it does business in; the impact of the regulatory environment as well as national, state, and local laws and regulations including, without limitation, those governing Partnerships; and the impact of general economic conditions upon rental rates and occupancy levels at the real estate facilities that the Partnership has an interest in. General ------- PS Partners IV, Ltd. (the "Partnership") is a publicly held limited partnership formed under the California Uniform Limited Partnership Act. Commencing in December 1984, 128,000 units of limited partnership interest (the "Units") were offered to the public in an interstate offering. The offering was completed in July 1985. The Partnership has reported annually to the Securities and Exchange Commission on Form 10-K which includes financial statements certified by independent public accountants. The Partnership has also reported quarterly to the Securities and Exchange Commission on Form 10-Q and includes unaudited financial statements with such filings. The Partnership expects to continue such reporting. The Partnership was formed to invest in and operate existing self-service facilities offering storage space for personal and business use (the "mini-warehouses") and to invest up to 40% of the net proceeds of the offering in and operate existing office and industrial properties. The Partnership's real estate investments consist of wholly-owned facilities and an investment in a general partnership (SEI/PSP IV Joint Ventures, the "Joint Venture") with Public Storage, Inc. ("PSI"), a real estate investment trust ("REIT") organized as a corporation under the laws of California. The Partnership's general partners (the "General Partners") are PSI and B. Wayne Hughes ("Hughes"). Hughes is the chairman of the board and chief executive officer of PSI, and Hughes and members of his family (the "Hughes Family") are the major shareholders of PSI. The Partnership is managed, and its investment decisions are made by Hughes and the executive officers and directors of PSI. The limited partners of the Partnership have no right to participate in the management or conduct of its business affairs. PSI believes that it is the largest operator of mini-warehouse facilities in the United States. Through 1996, the business parks of the Joint Venture were managed by Public Storage Commercial Properties Group, Inc. ("PSCPG") pursuant to a Management Agreement. In January 1997, the Joint Venture and PSI and other related partnerships transferred a total of 35 business parks to PS Business Parks, L.P. ("PSBPLP"), formerly known as American Office Park Properties, L.P., an operating partnership formed to own and operate business parks in which PSI has a significant interest. Included among the properties transferred were the business parks of the Joint Venture in exchange for a partnership interest in PSBPLP. Until March 17, 1998, the general partner of PSBPLP was American Office Park Properties, Inc., an affiliate of PSI. On March 17, 1998, American Office Park Properties, Inc. was merged into Public Storage Properties XI, Inc., which changed its name to PS Business Parks, Inc. ("PSBP"). PSBP is a REIT affiliated with PSI, and is publicly traded on the American Stock Exchange. As a result of the merger, PSBP became the general partner of PSBPLP (which changed its name from American Office Park Properties, L.P. to PS Business Parks, L.P.). See Item 13. 2 PSI's current relationship with the Partnership includes (i) the joint ownership of the Joint Venture which owns 32 of the Partnership's 33 properties and 599,340 operating partnership units in PSBPLP, (ii) PSI is a co-general partner along with Hughes, who is chairman of the board and chief executive officer of PSI, (iii) as of January 1, 2002, PSI owned approximately 58.7% of the Partnership's limited partnership units, and (iv) PSI is the operator of the 33 properties in which the Partnership has an interest (these 33 properties are referred to collectively hereinafter as the "Mini-Warehouse Properties"). Investment Objectives and Policies ---------------------------------- The Partnership's objectives are to (i) preserve and protect invested capital, (ii) maximize the potential for appreciation in value of its investments, (iii) provide Federal income tax deductions so that during the early years of property operations a portion of cash distributions may be treated as a return of capital for tax purposes, and therefore, may not represent taxable income to the limited partners, and (iv) provide for cash distributions from operations. The Partnership will terminate on December 31, 2038, unless dissolved earlier. Under the terms of the general partnership agreement with PSI, PSI has the right to require the Partnership to sell all of the properties owned by the Joint Venture (see Item 12(c)). Following are the Partnership's investment practices and policies. The Partnership does not anticipate making any additional investments other than maintenance capital expenditures and does not anticipate liquidating the investments it now holds. While a vote of the limited partners is generally required to change the Partnership's investment policies, PSI holds a majority of the limited partnership units, and as a result, the General Partners could change these policies through PSI's vote. o Our investments consists of (i) a wholly-owned self-storage facility and (ii) an interest in the Joint Venture which owns 32 self storage facilities and 599,340 operating partnership units in PSBPLP. All of these investments are in real estate or real estate entities holding real estate located in the United States. See "mini-warehouses" and Item 2 "Properties" for further information. These investments were acquired both for income and capital gains. o There is no limitation on the amount or percentage of assets which can be invested in any specific person. o The Partnership does not anticipate borrowing money, issuing senior securities, making loans to other persons, investing in the securities of other issuers for the purpose of exercising control, underwriting the securities of other issuers, engaging in the purchase and sale of investments, offering securities in exchange for property, or repurchasing or otherwise reacquiring its outstanding securities. Competition ----------- Competition in the market areas in which the Partnership operates is significant and affects the occupancy levels, rental rates and operating expenses of certain of the Partnerships facilities. Recent increases in development of mini-warehouse facilities have intensified the competition among mini-warehouse operators in many market areas in which the Partnership operates. In recent years consolidation has occurred in the fragmented mini-warehouse industry. The Partnership believes that the significant operating and financial experience of PSI's officers and directors, combined with the Partnership's geographic diversity, economies of scale and the "Public Storage" name, should enable the Partnership to continue to compete effectively with other entities. 3 Business Attributes ------------------- Under PSI operation, the Partnership's facilities are part of a comprehensive distribution system encompassing standardized procedures, integrated reporting and information networks and centralized marketing. This distribution system is designed to maximize revenue through pricing and occupancy. The distribution system was significantly enhanced during 1996 with the introduction and implementation of the national telephone reservation center and new facility management software. NATIONAL TELEPHONE RESERVATION SYSTEM: Commencing in early 1996, PSI began to implement a national telephone reservation system designed to provide added customer service and maximize utilization of available mini-warehouse space. Customers calling either the PSI's toll-free telephone referral system, (800) 44-STORE, or a mini-warehouse facility are directed to the national reservation system where a representative discusses with the customer space requirements, price and location. PSI believes that the national telephone reservation system has enhanced the Partnership's ability to effectively market mini-warehouses and is primarily responsible for the Partnership's increasing occupancy levels and realized rental rates experienced at the mini-warehouse facilities during the past three years. ECONOMIES OF SCALE: PSI is the largest provider of mini-warehouse space in the industry. As of December 31, 2001, PSI operated 1,414 mini-warehouse facilities (including 30 managed for third parties) in 37 states and had over 659,000 spaces rented. The size and scope of PSI's operations have enabled it to achieve a consistently high level of profit margins and low level of administrative costs relative to revenues. BRAND NAME RECOGNITION: The Partnership's operations are conducted under the "Public Storage" brand name, which the Partnership believes is the most recognized and established name in the mini-warehouse industry. PSI manages mini-warehouse operations conducted in 37 states, giving it national recognition and prominence. PSI focuses its operations within those states in the major metropolitan markets. This concentration establishes PSI as one of the dominant providers of storage space in each market that it operates in and enables it to use a variety of promotional activities, such as television and radio advertising as well as targeted discounting and referrals, which are generally not economically viable to its competitors. Mini-warehouses --------------- Mini-warehouses, which comprise the majority of the Partnership's investments, are designed to offer accessible storage space for personal and business use at a relatively low cost. A user rents a fully enclosed space which is for the user's exclusive use and to which only the user has access on an unrestricted basis during business hours. On-site operation is the responsibility of resident managers who are supervised by area managers. Some mini-warehouses also include rentable uncovered parking areas for vehicle storage. Leases for mini-warehouse space may be on a long-term or short-term basis, although typically spaces are rented on a month-to-month basis. Rental rates vary according to the location of the property and the size of the storage space. Users of space in mini-warehouses include both individuals and large and small businesses. Individuals usually employ this space for storage of, among other things, furniture, household appliances, personal belongings, motor vehicles, boats, campers, motorcycles and other household goods. Businesses normally employ this space for storage of excess inventory, business records, seasonal goods, equipment and fixtures. The Mini-Warehouse Properties generally consist of three to seven buildings containing an aggregate of between 294 to 847 storage spaces, most of which have between 25 and 400 square feet and an interior height of approximately 8 to 12 feet. The Mini-Warehouse Properties experience minor seasonal fluctuations in the occupancy levels of mini-warehouses with occupancies higher in the summer months than in the winter months. The Partnership believes that these fluctuations result in part from increased moving activity during the summer. 4 The Mini-Warehouse Properties are geographically diversified and are generally located in heavily populated areas and close to concentrations of apartment complexes, single family residences and commercial developments. However, there may be circumstances in which it may be appropriate to own a property in a less populated area, for example, in an area that is highly visible from a major thoroughfare and close to, although not in, a heavily populated area. Moreover, in certain population centers, land costs and zoning restrictions may create a demand for space in nearby less populated areas. As with most other types of real estate, the conversion of mini-warehouses to alternative uses in connection with a sale or otherwise would generally require substantial capital expenditures. However, the Partnership and the Joint Venture do not intend to convert the Mini-Warehouse Properties to other uses. Mini-warehouse Property Operator -------------------------------- The Mini-Warehouse Properties are managed by PSI pursuant to a Management Agreement. Under the supervision of the Partnership and the Joint Venture, PSI coordinates the operation of the facilities, establishes rental policies and rates, directs marketing activity and directs the purchase of equipment and supplies, maintenance activity, and the selection and engagement of all vendors, supplies and independent contractors. PSI engages, at the expense of the property owner, employees for the operation of the owner's facilities, including resident managers, assistant managers, relief managers, and billing and maintenance personnel. Some or all of these employees may be employed on a part-time basis and may also be employed by other persons, partnerships, REITs or other entities owning facilities operated by PSI. In the purchasing of services such as advertising (including broadcast media advertising) and insurance, PSI attempts to achieve economies by combining the resources of the various facilities that it operates. Facilities operated by PSI have historically carried comprehensive insurance, including fire, earthquake, liability and extended coverage. PSI has developed systems for space inventory, accounting and handling delinquent accounts, including a computerized network linking PSI operated facilities. Each project manager is furnished with detailed operating procedures and typically receives facilities management training from PSI. Form letters covering a variety of circumstances are also supplied to the project managers. A record of actions taken by the project managers when delinquencies occur is maintained. The Mini-warehouse Properties are typically advertised via signage, yellow pages, flyers and broadcast media advertising (television and radio) in geographic areas in which many of the facilities are located. Broadcast media and other advertising costs are charged to the facilities located in geographic areas affected by the advertising. From time to time, PSI adopts promotional programs, such as temporary rent reductions, in selected areas or for individual facilities. For as long as the Management Agreement is in effect, PSI has granted the Partnership and the Joint Venture a non-exclusive license to use two PSI service marks and related designs, including the "Public Storage" name, in conjunction with rental and operation of facilities managed pursuant to the Management Agreement. Upon termination of the Management Agreement, the Partnership and the Joint Venture would no longer have the right to use the service marks and related designs. The General Partners believe that the loss of the right to use the service marks and related designs could have a material adverse effect on the Partnership's business. The Management Agreement with PSI provides that the Management Agreement may be terminated without cause upon 60 days written notice by the Partnership or six months notice by PSI. 5 Other Business Activities ------------------------- A Corporation that reinsures policies against losses to goods stored by tenants in PSI's storage facilities was purchased by PSI from Mr. Hughes and members of his family (the "Hughes Family") on December 31, 2001. We believe that the availability of insurance reduces our potential liability to tenants for losses to their goods from theft or destruction. This Corporation receives the premiums and bears the risks associated with the re-insurance. A subsidiary of PSI sells locks and boxes and rents trucks to the general public and tenants to be used in securing their spaces and moving their goods. We believe that the availability of locks and boxes for sale and the rental of trucks promote the rental of spaces. Federal Income Tax ------------------ PS Partners IV, Ltd. is treated as a partnership for federal income tax purposes with the taxable income of the entity allocated to each partners in accordance with the partnership agreement. Employees --------- There are approximately 120 persons who render services on behalf of the Partnership and the Joint Venture. These persons include resident managers, assistant managers, relief managers, district managers, and administrative personnel. Some of these employees may be employed on a part-time basis and may also be employed by other persons, partnerships, REITs or other entities owning facilities operated by PSI or PSBPLP. ITEM 1A. Risk Factors. ------------- In addition to the other information in our Form 10-K, you should consider the following factors in evaluating the Partnership: PUBLIC STORAGE CONTROLS US. Public Storage owns approximately 58.7% of our outstanding limited partnership units and is our general partner. Consequently, Public Storage controls matters submitted to a vote of our unitholders, including amending our organizational documents, dissolving the Partnership and approving other extraordinary transactions. SINCE OUR BUSINESS CONSISTS PRIMARILY OF ACQUIRING AND OPERATING REAL ESTATE, WE ARE SUBJECT TO REAL ESTATE OPERATING RISKS. The value of our investments may be reduced by general risks of real estate ownership. Since we derive substantially all of our income from real estate operations, we are subject to the general risks of owning real estate-related assets, including: o lack of demand for rental spaces or units in a locale; o changes in general economic or local conditions; o changes in supply of or demand for similar or competing facilities in an area; o potential terrorists attacks; o the impact of environmental protection laws; 6 o changes in interest rates and availability of permanent mortgage funds which may render the sale or financing of a property difficult or unattractive; and o changes in tax, real estate and zoning laws. There is significant competition among self-storage facilities. All of the properties the Partnership has an interest in are self-storage facilities. Competition in the market areas in which many of our properties are located is significant and has affected the occupancy levels, rental rates and operating expenses of some of our properties. Any increase in availability of funds for investment in real estate may accelerate competition. Further development of self-storage facilities may intensify competition among operators of self-storage facilities in certain market areas in which we operate. We may incur significant environmental costs and liabilities. As an owner of real properties, under various federal, state and local environmental laws, we are required to clean up spills or other releases of hazardous or toxic substances on or from our properties. Certain environmental laws impose liability whether or not the owner knew of, or was responsible for, the presence of the hazardous or toxic substances. In some cases, liability may not be limited to the value of the property. The presence of these substances, or the failure to properly remediate any resulting contamination, also may adversely affect the owner's or operator's ability to sell, lease or operate its property or to borrow using its property as collateral. We have conducted preliminary environmental assessments on the properties the Partnership has an interest in to evaluate the environmental condition of, and potential environmental liabilities associated with, our properties. These assessments generally consist of an investigation of environmental conditions at the property (not including soil or groundwater sampling or analysis), as well as a review of available information regarding the site and publicly available data regarding conditions at other sites in the vicinity. In connection with these property assessments, we have become aware that prior operations or activities at some facilities or from nearby locations have or may have resulted in contamination to the soil or groundwater at these facilities. In this regard, some of our facilities are or may be the subject of federal or state environment investigations or remedial actions. Although we cannot provide any assurance, based on the preliminary environmental assessments, we believe we have funds available to cover any liability from environmental contamination or potential contamination and we are not aware of any environmental contamination of our facilities material to our overall business, financial condition or results of operation. 7 ITEM 2. Properties. ----------- The following table sets forth information as of December 31, 2001, about the properties that the Partnership has an interest in:

9 The weighted average occupancy level for the Mini-Warehouse Properties was 86% in 2001 and 88% in 2000. The annual average realized rent per square foot for the Mini-Warehouse Properties was $8.88 in 2001 compared to $8.27 in 2000. There are no mortgages or other encumbrances of any of the Properties. The Partnership does not have any agreements to buy or sell any real estate nor does it expect to further develop any of its facilities except for capital improvements. ITEM 3. Legal Proceedings. ------------------ No material legal proceeding is pending against the Partnership or the Joint Venture. ITEM 4. Submission of Matters to a Vote of Security Holders. ---------------------------------------------------- No matters were submitted to a vote of security holders during the fourth quarter of 2001. PART II ITEM 5. Market for the Partnership's Common Equity and Related Stockholder ------------------------------------------------------------------ Matters. -------- The Partnership has no common stock. The Units are not listed on any national securities exchange or quoted on the NASDAQ System, and there is no established public trading market for the Units. Secondary sales activity for the Units has been limited and sporadic. The General Partners monitor transfers of the Units (a) because the admission of the transferee as a substitute limited partner requires the consent of the General Partners under the Partnership's Amended and Restated Agreement of Limited Partnership, (b) in order to ensure compliance with safe harbor provisions to avoid treatment as a "publicly traded partnership" for tax purposes and (c) because PSI has purchased Units. However, the General Partners do not have information regarding the prices at which all secondary sale transactions in the Units have been effectuated. Various organizations offer to purchase and sell limited partnership interests (including securities of the type such as the Units) in secondary sales transactions. Various publications such as The Stanger Report summarize and report information (on a monthly, bimonthly or less frequent basis) regarding secondary sales transactions in limited partnership interests (including the Units), including the prices at which such secondary sales transactions are effectuated. Exclusive of the General Partners' interest in the Partnership, as of December 31, 2001, there were approximately 2,380 record holders of Units. In February 1997, PSI completed a cash tender offer, which had commenced in December 1996, pursuant to which PSI acquired a total of 14,787 limited partnership units at $300 per Unit. The Partnership makes quarterly distributions of all "Cash Available for Distribution" and will make distributions of "Cash from Sales or Refinancing". Cash Available for Distribution is cash flow from all sources less cash necessary for any obligations or capital improvements, or reserves. Reference is made to Items 6 and 7 hereof for information on the amount of such distributions. 10 ITEM 6. Selected Financial Data. ------------------------

(a) Limited partners' per unit data is based on the weighted average number of units outstanding (128,000) during the year. (b) The General Partners distributed, concurrent with the distributions for the first quarter of 1999, a portion of the Partnership's operating reserve estimated to be $21.92 per Unit. The General Partners distributed, concurrent with the distribution for the second quarter of 2001, a portion of the operating reserve estimated to be $18.45 per Unit. 11 ITEM 7. Management's Discussion and Analysis of Financial Condition and Results ----------------------------------------------------------------------- of Operations ------------- Forward Looking Statements -------------------------- When used within this document, the words "expects," "believes," "anticipates," "should," "estimates," and similar expressions are intended to identify "forward-looking statements". Such forward-looking statements involve known and unknown risks, uncertainties, and other factors, which may cause the actual results and performance of the Partnership to be materially different from those expressed or implied in the forward looking statements. Such factors described in Item 1A, "Risk Factors", include the impact of competition from new and existing storage and commercial facilities which could impact rents and occupancy levels at the Partnership's facilities; the Partnership's ability to evaluate, finance, and integrate acquired and developed properties into the Partnership's existing operations; the Partnership's ability to effectively compete in the markets in which it does business; the impact of the regulatory environment as well as national, state, and local laws and regulations including, without limitation, those governing real estate investment trusts and the impact of general economic conditions upon rental rates and occupancy levels at the Partnership's facilities. Critical Accounting Policy - Impairment of Long Lived Assets ------------------------------------------------------------ Substantially all of the Partnership's assets consist of investments in real estate assets. We annually evaluate our real estate investments for impairment. This evaluation includes identifying indicators of impairment. When indicators of impairment are present and the undiscounted future cash flows of the assets are less than the carrying amount, an impairment charge is recorded. The Partnership has determined at December 31, 2001 that no such impairments existed and, accordingly, no impairment charges have been recorded. The Financial Accounting Standards Board ("FASB") has recently issued Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment and Disposal of Long-Lived Assets" ("SFAS 144"). This Statement addresses the procedures to be followed in evaluating and recording impairment losses with respect to long-lived assets. The Partnership will adopt this Statement in its fiscal year ended December 31, 2002, and expects that there will be no material impact from this Statement with respect to impairment losses. However, future events could cause us to conclude that our real estate investments are impaired. Any resulting impairment loss could have a material adverse impact on our financial condition and results of operations. Results of Operations --------------------- YEAR ENDED DECEMBER 31, 2001 COMPARED TO YEAR ENDED DECEMBER 31, 2000: The Partnership's net income was $3,902,000 in 2001 compared to $3,418,000 in 2000, representing an increase of $484,000, or 14.2%. The increase is due primarily to the Partnership's share of an improvement in operations of the mini-warehouses in which the Partnership has an interest (the "Mini-Warehouse Properties") and a decrease in depreciation allocated to the Partnership with respect to the joint venture. PROPERTY OPERATIONS: Rental income for the Partnership's wholly-owned mini-warehouse property was $327,000 in 2001 compared to $319,000 in 2000, representing an increase of $8,000, or 2.5%. Cost of operations (including management fees) remained stable at $137,000 for 2001 and 2000. Accordingly, for the Partnership's wholly-owned mini-warehouse property, property net operating income increased by $8,000, or 4.4%, from $182,000 in 2000 to $190,000 in 2001. EQUITY IN EARNINGS OF REAL ESTATE ENTITIES: Equity in earnings of real estate entities was $3,765,000 in 2001 as compared to $3,262,000 during 2000, representing an increase of $503,000, or 15.4%. The increase is due primarily to the Partnership's share of an improvement in operations of the Mini-Warehouse Properties and a decrease in depreciation allocated to the Partnership with respect to the joint venture. 12 DEPRECIATION AND AMORTIZATION: Depreciation and amortization increased $6,000, or 8.6%, from $70,000 in 2000 to $76,000 during 2001. YEAR ENDED DECEMBER 31, 2000 COMPARED TO YEAR ENDED DECEMBER 31, 1999: The Partnership's net income was $3,418,000 in 2000 compared to $2,974,000 in 1999, representing an increase of $444,000, or 14.9%. The increase is due primarily to the Partnership's share of increased operating results of PSBPLP and a decrease in depreciation allocated to the Partnership with respect to the joint venture, offset partially by the Partnership's share of a decrease in property net operating income of the Mini-Warehouse Properties. PROPERTY OPERATIONS: Rental income for the Partnership's wholly-owned mini-warehouse property was $319,000 in 2000 compared to $306,000 in 1999, representing an increase of $13,000, or 4.2%. Cost of operations (including management fees) decreased $7,000, or 4.9%, to $137,000 during 2000 from $144,000 in 1999. Accordingly, for the Partnership's wholly-owned mini-warehouse property, property net operating income increased by $20,000, or 12.3%, from $162,000 in 1999 to $182,000 in 2000. EQUITY IN EARNINGS OF REAL ESTATE ENTITIES: Equity in earnings of real estate entities was $3,262,000 in 2000 as compared to $2,920,000 during 1999, representing an increase of $342,000, or 11.7%. This increase was due primarily to the Partnership's share of increased operating results of PSBPLP and a decrease in depreciation allocated to the Partnership with respect to the joint venture, offset partially by the Partnership's share of a decrease in property net operating income at the Mini-Warehouse Properties. The increase also includes $108,000 representing the Partnership's share of a gain on sale of real estate investments recorded by PSBPLP in 2000. DEPRECIATION AND AMORTIZATION: Depreciation and amortization increased $1,000, or 1.4%, from $69,000 in 1999 to $70,000 during 2000. This increase was primarily attributable to the depreciation of capital expenditures made during 1999 and 2000. Supplemental Property Data -------------------------- During 2001 and 2000, a majority of the Partnership's net income was from the Partnership's share of the operating results of the Mini-Warehouse Properties. Therefore, in order to evaluate the Partnership's operating results, the General Partners analyze the operating performance of the Mini-Warehouse Properties. YEAR ENDED DECEMBER 31, 2001 COMPARED TO THE YEAR ENDED DECEMBER 31, 2000: Rental income for the Mini-Warehouse Properties was $13,921,000 in 2001 compared to $13,183,000 during 2000, representing an increase of $738,000, or 5.6%. The increase in rental income was primarily attributable to increased rental rates. The annual average realized rent per square foot was $8.88 in 2001 compared to $8.27 in 2000. The weighted average occupancy level was 88% in 2000 and 86% in 2001. Cost of operations (including management fees) increased $124,000, or 2.3%, to $5,440,000 during 2001 from $5,316,000 in 2000. This increase was primarily attributable to increases in advertising and property tax expense. Accordingly, for the Mini-Warehouse Properties, property net operating income increased by $614,000, or 7.8%, from $7,867,000 in 2000 to $8,481,000 during 2001. YEAR ENDED DECEMBER 31, 2000 COMPARED TO THE YEAR ENDED DECEMBER 31, 1999: Rental income for the Mini-Warehouse Properties was $13,183,000 in 2000 compared to $13,130,000 during 1999, representing an increase of $53,000, or 0.4%. The increase in rental income was primarily attributable to increased rental rates. The annual average realized rent per square foot was $8.27 in 2000 compared to $8.02 in 1999. The weighted average occupancy level was 90% in 1999 and 88% in 2000. Cost of operations (including management fees) increased $239,000, or 4.7%, to $5,316,000 during 2000 from $5,077,000 in 1999. This increase was primarily attributable to increases in advertising, repairs and maintenance, and property tax expenses. Accordingly, for the Mini-Warehouse Properties, property net operating income decreased by $186,000, or 2.3%, from $8,053,000 in 1999 to $7,867,000 during 2000. 13 Liquidity and Capital Resources ------------------------------- The Partnership has adequate sources of cash to finance its operations, both on a short-term and a long-term basis, primarily by internally generated cash from property operations and distributions from Real Estate Entities, combined with cash on-hand at December 31, 2001 totaling $1,741,000. Cash flows from operating activities and distributions from Real Estate Entities (totaling $4,168,000 for the year ended December 31, 2001) have been sufficient to meet all current obligations of the Partnership. Total capital improvements for the Partnership's wholly-owned property were $5,000, $35,000 and $3,000 in 2001, 2000 and 1999, respectively. During 2002, the Partnership anticipates approximately $12,000 of capital improvements to the Partnership's wholly-owned properties. Total distributions paid to the General Partners and the limited partners (including per Unit amounts) for 2001 and prior years were as follows: Total Per Unit ------------------- ------------------- 2001 $6,149,000 $42.80 2000 2,600,000 18.10 1999 5,150,000 35.84 1998 2,000,000 13.92 1997 2,000,000 13.92 1996 2,999,000 20.88 1995 4,899,000 34.10 1994 2,816,000 19.60 1993 2,442,000 17.00 1992 2,968,000 20.66 1991 3,607,000 25.11 1990 3,144,000 21.89 1989 3,097,000 21.56 1988 3,769,000 26.23 1987 3,770,000 26.23 1986 3,593,000 25.00 The Partnership, in prior years, made regular distributions based on estimated cash available for distribution (cash flow from all sources, less cash necessary for capital improvement needs and to establish reserves). The General Partners would periodically make special distributions if cash available for distribution exceeded its original estimates or if it adjusted the Partnership's cash reserve levels. The General Partners distributed, concurrent with the regular distribution for the second quarter of 2001, a special distribution of $18.45 per Unit. Future distribution levels will be based on the General Partners' estimate of on-going cash flow available for distributions (cash flows from operations and distributions from Real Estate Entities less capital improvements and necessary cash reserves). The Partnership does not anticipate any material changes in its reserve requirements for capital improvements or other items. ITEM 7A.

Security Ownership of Certain Beneficial Owners and Management. --------------------------------------------------------------- (a) At March 15, 2002, PSI beneficially owned more than 5% or more of the Units of the Partnership: Title Amount of Percent of Name and Address of Beneficial of Class Beneficial Owner Ownership Class ---------------- ----------------------- ---------------- -------- Units of Limited Public Storage, Inc. Partnership 701 Western Avenue Interest Glendale, CA 91201 (1) 75,149 Units (1) 58.7% ---------- (1) These Units are held of record by SEI Arlington Acquisition Corporation, a wholly-owned subsidiary of PSI. The Partnership is not aware of any other beneficial owners of more than 5% of the Units. (b) The Partnership has no officers and directors. The General Partners of the Partnership are PSI and B. Wayne Hughes, the Chairman of PSI. These general partners have the powers and duties of a general partner, such as management, conduct and operation of the Partnership as denoted in the Partnership agreement. In addition, they have the liabilities associated with being a general partner of the Partnership. The General Partners have contributed $646,000 to the capital of the Partnership representing 1% of the aggregate capital contributions and as a result participate in the distributions to the limited partners and in the Partnership's profits and losses in the same proportion that the general partners' capital contribution bears to the total capital contribution (approximately $517,000 was contributed by PSI and approximately $129,000 was contributed by Mr. Hughes). In addition, the General Partners' interest includes additional distribution rights as outlined in Item 13. Certain Relationships and Related Transactions. In 1993, Mr. Hughes sold his ownership and rights to distributions from the Partnership to Public Storage. As such, Mr. Hughes continues to act as a general partner but receives no compensation or other consideration from the Partnership. Mr. Hughes has no other interests in the Partnership. (c) The Partnership knows of no contractual arrangements, the operation of the terms of which may at a subsequent date result in a change in control of the Partnership, except for articles 16, 17 and 21.1 of the Partnership's Amended Certificate and Agreement of Limited Partnership, a copy of which is included in the Partnership's prospectus included in the Partnership's Registration Statement File No. 2-92009. Those articles provide, in substance, that the limited partners shall have the right, by majority vote, to remove a general partner and that a general partner may designate a successor with the consent of the other general partner and a majority of the limited partners. 18 The Partnership owns interests in 33 properties (which exclude the properties transferred to PSBPLP in January 1997); 32 of such properties are held in a general partnership comprised of the Partnership and PSI. Under the terms of the partnership agreement relating to the ownership of the properties, PSI has the right to compel a sale of each property at any time after seven years from the date of acquisition at not less than its independently determined fair market value provided the Partnership receives its share of the net sales proceeds solely in cash. As of December 31, 2001, PSI has the right to require the Partnership to sell all of the Joint Venture's properties on these terms. ITEM 13. Certain Relationships and Related Transactions. ----------------------------------------------- The Partnership Agreement provides that the General Partners and their affiliates are entitled to the following compensation: 1. Incentive distributions equal to 10% of Cash Flow from Operations. 2. Provided the limited partners have received distributions equal to 100% of their investment plus a cumulative 8% per year (not compounded) on their investment (reduced by distributions other than from Cash Flow from Operations), subordinated incentive distributions equal to 15% of remaining Cash from Sales or Refinancings. 3. Provided the limited partners have received distributions equal to 100% of their capital contributions plus a cumulative 6% per year (not compounded) on their investment (reduced by distributions other than distributions from Cash Flow from Operations), brokerage commissions at the lesser of 3% of the sales price of a property or 50% of a competitive commission. During 2001, approximately $615,000 was paid to PSI with respect to items 1, 2, and 3 above. Mr. Hughes was paid no amounts with respect to items 1, 2, and 3 and receives no compensation as general partner because PSI has acquired Mr. Hughes' ownership and distribution rights in the Partnership. The Partnership owns interests in 33 properties (which exclude the properties transferred to PSBPLP in January 1997); 32 of such properties are held in a general partnership comprised of the Partnership and PSI. The Partnership and the Joint Venture have a Management Agreement with PSI pursuant to which the Partnership and the Joint Venture pay PSI a fee of 6% of the gross revenues of the mini-warehouse spaces operated for the Partnership and the Joint Venture. For as long as the Management Agreement is in effect, PSI has granted the Partnership and the Joint Venture a non-exclusive license to use two PSI service marks and related designs, including the "Public Storage" name, in conjunction with rental and operation of facilities managed pursuant to the Management Agreement. Upon termination of the Management Agreement, the Partnership and Joint Venture would no longer have the right to use the service marks ad related designs. The General Partners believe that the loss of the right to use the service marks and related designs could have a material adverse effect on the Partnership's business. The Management Agreement with PSI provides that the Management Agreement may be terminated without cause upon 60 days written notice by the Partnership or 6 months notice by PSI. During 2001, the Partnership and the Joint Venture paid fees of $838,000 to PSI pursuant to the Management Agreement. The Partnership and PSI have joint ownership in SEI/PSP IV Joint Ventures, which owns 32 of the 33 properties that the Partnership has an interest in, as well as 599,340 operating partnership units in PSBPLP. Pursuant to a Participation Agreement among PSI and the Partnership, the Partnership manages SEI/PSP Partners IV Joint Ventures although PSI may compel the sale of a property owned by the Joint Venture and each has a right of first refusal to acquire the other's interest in the event of a proposed sale of a property owned by the Joint Venture. 19 Through 1996, the Joint Venture business parks were managed by a predecessor of PSBPLP pursuant to a Management Agreement which provides for the payment of a fee by the Joint Venture of 5% of the gross revenues of the commercial space operated for the Joint Venture. In January 1997, the Joint Venture, PSI and other affiliated entities transferred a total of 35 business parks to PSBPLP, an operating partnership formed to own and operate business parks in which PSI has a significant interest. Included among the properties transferred were the Joint Venture's business parks in exchange for a partnership interest in PSBPLP. The general partner of PSBPLP is PS Business Parks, Inc., a REIT traded on the American Stock Exchange. As of December 31, 2001, the Joint Venture owned approximately 2%, PSI and its subsidiaries (excluding the Partnership) owned approximately 42% and Mr. Hughes and his family owned less than 1% of the outstanding common partnership interests of PSBPLP, respectively.

Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ Description of Partnership -------------------------- PS Partners IV, Ltd. (the "Partnership") was formed with the proceeds of an interstate public offering. PSI Associates II, Inc. ("PSA"), an affiliate of Public Storage Management, Inc., organized the Partnership along with B. Wayne Hughes ("Hughes"). In September 1993, Storage Equities, Inc., now known as Public Storage Inc. ("PSI") acquired the interest of PSA relating to its general partner capital contribution in the Partnership and was substituted as a co-general partner in place of PSA. In 1995, there was a series of mergers among Public Storage Management, Inc. (which was the Partnership's mini-warehouse operator), Public Storage, Inc. and their affiliates (collectively, "PSMI"), culminating in the November 16, 1995 merger (the "PSMI Merger") of PSMI into Storage Equities, Inc. In the PSMI Merger, Storage Equities, Inc. was renamed Public Storage, Inc. and it acquired substantially all of PSMI's United States real estate operations and became the operator of the mini-warehouse properties in which the Partnership has an interest. The Partnership has invested in existing mini-warehouse storage facilities which offer self-service storage spaces for lease, usually on a month-to-month basis, to the general public and, to a lesser extent, in existing business park facilities which offer industrial and office space for lease. The Partnership has ownership interests in 33 properties in 15 states (collectively referred to as the "Mini-Warehouse Properties"), which exclude three properties transferred to PS Business Parks, L.P. ("PSBPLP") in January 1997. Thirty-two of the properties are owned by SEI/PSP IV Joint Ventures (the "Joint Venture"), a general partnership between the Partnership and PSI. The Partnership is the managing general partner of the Joint Venture, with ownership interests in the individual properties of the Joint Venture ranging from 49.8% to 50.9%. As used hereinafter, the Joint Venture and PSBPLP are referred to as the "Real Estate Entities." Basis of Presentation --------------------- The financial statements include the accounts of the Partnership. The accounts of the Joint Venture, which the Partnership does not control, are not consolidated with the Partnership and the Partnership's interest in the Joint Venture is accounted for on the equity method. The Partnership does not control the Joint Venture because PSI has significant control rights with respect to the management of the properties, including the right to compel the sale of each property in the Joint Venture and the right to require the Partnership to submit operating budgets. Under the terms of the general partnership agreement of the Joint Venture all depreciation and amortization with respect to each property is allocated solely to the Partnership until the limited partners recover their initial capital contribution. Thereafter, all depreciation and amortization is allocated solely to PSI until it recovers its initial capital contribution. All remaining depreciation and amortization is allocated to the Partnership and PSI in proportion to their ownership percentages. F-6 1. Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ (Continued) ----------- Under the terms of the partnership agreements, PSI has the right to compel the sale of each property in the general partnerships at any time after seven years from the date of acquisition at not less than its independently determined fair market value provided the Partnership receives its share of the net proceeds solely in cash. PSI's right to require the Partnership to sell all of the properties owned jointly with the Partnership has been exercisable in all periods presented. Under the terms of the general partnership agreement of the Joint Venture, for property acquisitions in which PSI issued convertible securities to the sellers for its interest, PSI's rights to receive cash flow distributions from the partnerships for any year after the first year of operation are subordinated to cash distributions to the Partnership equal to a cumulative annual 7% of its cash investment (not compounded). These agreements also specify that upon sale or refinancing of a property for more than its original purchase price, distribution of proceeds to PSI is subordinated to the return to the Partnership of the amount of its cash investment and the 7% distribution described above. Depreciation and amortization ----------------------------- The Partnership and the Joint Venture depreciate the buildings and equipment on a straight-line method over estimated useful lives of 25 and 5 years, respectively. Revenue Recognition ------------------- Property rents are recognized as earned. Allocation of Net Income or Loss -------------------------------- The General Partners' share of net income or loss consists of an amount attributable to their 1% capital contribution and an additional percentage of cash flow (as defined, see Note 4) which relates to the General Partners' share of cash distributions as set forth in the Partnership Agreement. All remaining net income or loss is allocated to the limited partners. Per Unit Data ------------- Per unit data is based on the number of limited partnership units (128,000) outstanding during the year. Cash Distributions ------------------ The Partnership Agreement provides for quarterly distributions of cash flow from operations (as defined). Cash distributions per unit were $42.80, $18.10 and $35.84 for 2001, 2000 and 1999, respectively. Cash and Cash Equivalents ------------------------- For financial statement purposes, the Partnership considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. F-7 1. Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ (Continued) ----------- Environmental Cost ------------------ Substantially all of the real estate facilities in which the Partnership has an interest were acquired prior to the time that it was customary to conduct extensive environmental investigations in connection with the property acquisitions. Although there can be no assurance, the Partnership is not aware of any environmental contamination of the Mini-Warehouse Properties which individually or in the aggregate would be material to the Partnership's overall business, financial condition, or results of operations. Segment Reporting ----------------- Effective January 1, 1998, the Partnership adopted SFAS No. 131, "Disclosure about Segments of an Enterprise and Related Information." SFAS No. 131 established standards for the way public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. SFAS No. 131 also establishes standards for related disclosures about products and services, geographic areas and major customers. The Partnership only has one reportable segment as defined within SFAS No. 131, therefore the adoption of SFAS No. 131 had no effect on the Partnership's disclosures. Use of Estimates ---------------- The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Recent Accounting Pronouncements and Guidance --------------------------------------------- Accounting for business combinations In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard No. 141, "Business Combinations," ("SFAS 141") which sets forth revised accounting guidance with respect to accounting for acquisitions of business enterprises. In accordance with the transition provisions of SFAS 141, the Partnership adopted the disclosure and accounting provisions of SFAS 141 on June 30, 2001 and the adoption had no impact on Partnership's financial statements. Accounting for goodwill and other intangible assets In June 2001, the FASB issued Statement of Financial Accounting Standard No. 142, "Goodwill and Other Intangible Assets," ("SFAS 142") which addresses how intangible assets that are acquired individually or with a group of other assets (but not those acquired in a business combination, which are addresses in SFAS 141) are to be accounted for. It also addresses how goodwill and other intangible assets should be accounted for after they have been initially recognized in the financial statements. In accordance with SFAS 142, the Partnership will adopt the provisions of SFAS No. 142 in its financial statements beginning with the year ending December 31, 2002. The adoption of SFAS 142 will have no impact upon the Partnership's financial position or results of operations. F-8 1. Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ (Continued) ----------- Recent Accounting Pronouncements and Guidance (Continued) --------------------------------------------------------- Accounting for the impairment and disposal of long-lived assets In August 2001, the FASB issued Statement of Financial Accounting Standards No. 144 ("SFAS 144") which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS 121, and the accounting and reporting provisions of APB Opinion No. 30, "Reporting the Results of Operations" for a disposal of a segment of a business. SFAS 144 is effective for fiscal years beginning after December 15, 2001, with earlier application encouraged. The Partnership expects to adopt SFAS 144 on January 1, 2002, and does not expect that the adoption of the Statement will have a material impact upon the Partnership's financial position or results of operations. 2. Real Estate Facilities ---------------------- In 1995, the Financial Accounting Standards Board issued Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" which requires impairment losses to be recorded on long-lived assets. We annually evaluate long-lived assets (including intangibles), by identifying indicators of impairment and, if such indicators exist, by comparing the sum of the estimated undiscounted future cash flows for each asset to the asset's carrying amount. When indicators of impairment are present and the sum of the undiscounted cash flows is less than the carrying value of such asset, an impairment loss is recorded equal to the difference between the asset's current carrying value and its value based upon discounting its estimated future cash flows. Statement No. 121 also addresses the accounting for long-lived assets that are expected to be disposed of. Such assets are to be reported at the lower of their carrying amount or fair value, less cost to sell. Our evaluations have indicated no impairment in the carrying amount of our assets. In January 1997, the Partnership, the Joint Venture and PSI and other related partnerships transferred a total of 35 business parks to PSBLP, an operating partnership formed to own and operate business parks in which PSI has a significant interest. Included among the properties transferred were the Partnership's and the Joint Venture's business parks in exchange for a partnership interest in PSBLP. The general partner of PSBLP is PS Business Parks, Inc. ("PSBP"). 3. Investment in Real Estate Entities ---------------------------------- During 2001, 2000 and 1999, the Partnership recognized earnings from the Real Estate Entities of $3,765,000, $3,262,000 and $2,920,000, respectively, and received cash distributions totaling $3,963,000, $3,840,000 and $3,895,000, respectively from the Real Estate Entities. Equity in earnings for 2000 includes $108,000, representing the Partnership's share of a gain on sale of real estate investments recorded by PSBPLP. F-9 3. Investment in Real Estate Entities (Continued) ---------------------------------------------- The accounting policies of the Real Estate Entities are similar to that of the Partnership. Summarized combined financial data with respect to the Real Estate Entities are as follows: 2001 2000 --------------- -------------- For the year ended December 31, Total revenues $ 185,088,000 $ 164,687,000 Minority interest in income 27,489,000 26,741,000 Net income 56,686,000 57,573,000 At December 31, Total assets, net of accumulated depreciation $ 1,223,031,000 $ 984,840,000 Total liabilities 211,346,000 61,024,000 Total minority interest 359,891,000 306,478,000 Total equity 651,794,000 617,338,000 The increase in the size of the combined financial position and operating results, respectively, of the Real Estate Entities for the year ended December 31, 2001 and at December 31, 2000, respectively, as compared to prior periods, is the result of additional properties acquired by PSBPLP during 2000 and 2001. Financial statements of the Joint Venture are filed with the Partnership's Form 10-K for 2001, in Item 14. PS Business Parks, Inc. is a registrant with the Securities and Exchange Commission, and its filings can be accessed through the Securities and Exchange Commission. 4. General Partners' Equity ------------------------ PSI and Hughes are general partners of the Partnership. In 1993, Hughes sold his ownership in and rights to distributions from the Partnership to PSI. As such, Hughes continues to act as a general partner but receives no compensation, distributions or other consideration from the Partnership. Hughes has no other interest in the Partnership. As such, PSI has a 1% interest in the Partnership with respect to the General Partners' contributed capital and an additional 10% interest in cash distributions attributable to operations, exclusive of distributions attributable to sales and refinancing proceeds. Proceeds from sales and refinancings will be distributed entirely to the limited partners until the limited partners recover their investment plus a cumulative 8% annual return (not compounded); thereafter, PSI has a 15% interest in remaining proceeds. 5. Related Party Transactions -------------------------- The Partnership has a management agreement with PSI whereby PSI operates the Mini-Warehouse Properties for a fee equal to 6% of the facilities' monthly gross revenue (as defined). For 2001, 2000 and 1999, the Partnership paid PSI $20,000 $20,000 and $18,000, respectively, pursuant to this management agreement. In January 1997, the Joint Venture transferred its business park facilities to PSBPLP in exchange for a partnership interest in PSBPLP. PSI has a significant economic interest in PSBPLP. F-10 6. Leases ------ The Partnership has invested primarily in existing mini-warehouse storage facilities which offer self-service storage spaces for lease to the general public. Leases for such space are usually on a month-to-month basis. 7. Taxes Based on Income --------------------- Taxes based on income are the responsibility of the individual partners and, accordingly, the Partnership's financial statements do not reflect a provision for such taxes. Unaudited taxable net income was $5,746,000, $4,568,000 and $3,615,000 for the years ended December 31, 2001, 2000 and 1999, respectively. The difference between taxable income and book income is primarily related to timing differences in depreciation expense. 8.

See accompanying note. F-18 SEI/PSP IV JOINT VENTURES NOTES TO FINANCIAL STATEMENTS December 31, 2001 1. Description of Partnership -------------------------- SEI/PSP IV Joint Ventures (the "Joint Venture") was formed on December 31, 1990 in connection with the consolidation of 23 separate general partnerships between Public Storage Inc. ("PSI") and PS Partners IV, Ltd. ("PSP IV"). The Joint Venture, through its predecessor general partnerships, invested in existing mini-warehouse facilities which offer self-service storage spaces for lease, usually on a month-to-month basis, to the general public and, to a lesser extent, in existing business park facilities which offer industrial and office space for lease. The Joint Venture owns 32 properties (referred to hereinafter as the "Mini-Warehouses"), which excludes three properties which were transferred to PS Business Parks, L.P. ("PSBPLP") in January 1997. PSP IV is the managing general partner of the Joint Venture, with its ownership interests in the properties of the Joint Venture ranging from 49.8% to 50.9%. 2. Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ Basis of Presentation --------------------- The financial statements include the accounts of the Joint Venture. Under the terms of the general partnership agreement of the Joint Venture, for property acquisitions in which PSI issued convertible securities to the sellers for its interest, PSI's right to receive cash flow distributions for any year after the first year of operation are subordinated to cash distributions to PSP IV equal to a cumulative annual 7% of its cash investment (not compounded). In addition, upon sale or refinancing of a property for more than its original purchase price, distribution of proceeds to PSI is subordinated to the return to PSP IV of the amount of its cash investment and the 7% distribution described above. Depreciation and amortization ----------------------------- The Joint Venture depreciates the buildings and equipment on a straight-line method over estimated useful lives of 25 and 5 years, respectively. Revenue and Expense Recognition ------------------------------- Property rents are recognized as earned. Advertising costs of $751,000, $589,000 and $485,000 in 2001, 2000 and 1999, respectively, are expensed as incurred. Allocation of Net Income to PSP IV and PSI ------------------------------------------ Net income prior to depreciation is allocated to PSP IV and PSI based upon their relative ownership interest in each property and the results of each property. Under the terms of the general partnership agreement of the Joint Venture all depreciation and amortization with respect to each Joint Venture is allocated solely to PSP IV until it recovers its initial capital contribution. Thereafter, all depreciation and amortization is allocated solely to PSI until it recovers its initial capital contribution. All remaining depreciation and amortization is allocated to PSP IV and PSI in proportion to their ownership percentages. F-19 2. Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ (Continued) ----------- Cash Distributions ------------------ The general partnership agreement of the Joint Venture provides for regular distributions of cash flow from operations (as defined). Cash and Cash Equivalents ------------------------- For financial statement purposes, the Joint Venture considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Environmental Cost ------------------ Substantially all of the real estate facilities in which the Joint Venture has an interest were acquired prior to the time that it was customary to conduct extensive environmental investigations in connection with the property acquisitions. Although there can be no assurance, the Joint Venture is not aware of any environmental contamination of the Mini-Warehouses which individually or in the aggregate would be material to the Joint Venture's overall business, financial condition, or results of operations. Segment Reporting ----------------- Effective January 1, 1998, the Joint Venture adopted SFAS No. 131, "Disclosure about Segments of an Enterprise and Related Information." SFAS No. 131 established standards for the way public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. SFAS No. 131 also establishes standards for related disclosures about products and services, geographic areas and major customers. The Joint Venture only has one reportable segment as defined within SFAS No. 131, therefore the adoption of SFAS No. 131 had no effect on the Joint Venture's disclosures. Use of Estimates ---------------- The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Recent Accounting Pronouncements and Guidance --------------------------------------------- Accounting for business combinations In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard No. 141, "Business Combinations," ("SFAS 141") which sets forth revised accounting guidance with respect to accounting for acquisitions of business enterprises.

F-20 2. Summary of Significant Accounting Policies and Partnership Matters ------------------------------------------------------------------ (Continued) ----------- Recent Accounting Pronouncements and Guidance (Continued) --------------------------------------------------------- Accounting for goodwill and other intangible assets In June 2001, the FASB issued Statement of Financial Accounting Standard No. 142, "Goodwill and Other Intangible Assets," ("SFAS 142") which addresses how intangible assets that are acquired individually or with a group of other assets (but not those acquired in a business combination, which are addresses in SFAS 141) are to be accounted for. It also addresses how goodwill and other intangible assets should be accounted for after they have been initially recognized in the financial statements. In accordance with SFAS 142, the Joint Venture will adopt the provisions of SFAS No. 142 in its financial statements beginning with the year ending December 31, 2002. The Joint Venture's adoption of SFAS 142 will have no impact upon the Joint Venture's financial position or results of operations. Accounting for the impairment and disposal of long-lived assets In August 2001, the FASB issued Statement of Financial Accounting Standards No. 144 ("SFAS 144") which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS 121, and the accounting and reporting provisions of APB Opinion No. 30, "Reporting the Results of Operations" for a disposal of a segment of a business. SFAS 144 is effective for fiscal years beginning after December 15, 2001, with earlier application encouraged. The Joint Venture expects to adopt SFAS 144 on January 1, 2002, and does not expect that the adoption of the Statement will have a material impact upon the Joint Venture's financial position or results of operations. 3.

Such assets are to be reported at the lower of their carrying amount or fair value, less cost to sell. Our evaluations have indicated no impairment in the carrying amount of our assets. In January 1997, the Joint Venture, PSI and other affiliated partnerships of PSI transferred a total of 35 business parks to PSBPLP, an operating partnership formed to own and operate business parks in which PSI has a significant interest. Included among the properties transferred was the Joint Venture's business parks in exchange for a partnership interest in PSBPLP. The general partner of PSBPLP is PS Business Parks, Inc. ("PSBP"). F-21 4.

Included in equity in earnings for 2000 is $162,000 representing the Joint Venture's share of PSBPLP's gains on sale of real estate investments. The accounting policies of PSBPLP are similar to that of the Joint Venture. Summarized combined financial data with respect to PSBPLP is as follows: 2001 2000 ----------------- ----------------- For the year ended December 31, Total revenues $ 170,391,000 $ 150,634,000 Minority interest in income 27,489,000 26,741,000 Net income 49,870,000 51,181,000 At December 31, Total assets, net of accumulated depreciation $ 1,169,955,000 $ 930,756,000 Total liabilities 210,333,000 59,935,000 Total minority interest 359,891,000 306,478,000 Total equity 599,731,000 564,343,000 The increase in the size of the combined financial position and operating results, respectively, of the Real Estate Entity for the year ended December 31, 2000 and at December 31, 2001, respectively, as compared to prior periods, is the result of additional properties acquired by PSBLP during 2000 and 2001. PS Business Parks, Inc., which owns PSBPLP, is a registrant with the Securities and Exchange Commission, and its filings can be accessed through the Securities and Exchange Commission. 5.
