BUSINESS Krupp Insured Mortgage Limited Partnership (the "Partnership") is a Massachusetts limited partnership which was formed on March 21, 1988. The Partnership raised approximately $299 million through a public offering of limited partner interests evidenced by units of depositary receipts ("Units"), and used the proceeds available for investment primarily to acquire participating insured mortgages ("PIMs") and mortgage-backed securities ("MBS"). The Partnership considers itself to be engaged only in the industry segment of investment in mortgages. The Partnership's investments in PIMs on multi-family residential properties consist of a MBS or an insured mortgage loan (collectively, the "insured mortgage") guaranteed or insured as to principal and basic interest. These insured mortgages were issued or originated under or in connection with the housing programs of the Government National Mortgage Association ("GNMA"), "Fannie Mae" or the Department of Housing and Urban Development ("HUD"). PIMs provide the Partnership with monthly payments of principal and basic interest and also may provide the Partnership with participation in the current revenue stream and in residual value, if any, from the sale or other realization of the underlying property. The borrower conveys these rights to the Partnership through a subordinated promissory note and mortgage. The participation features are neither insured nor guaranteed. The Partnership also acquired MBS collateralized by single-family mortgage loans issued or originated by Fannie Mae or the Federal Home Loan Mortgage Corporation ("FHLMC"). Fannie Mae and FHLMC guarantee the principal and basic interest of the Partnership's FNMA and FHLMC MBS, respectively. Proceeds received from prepayments or other realizations of mortgage assets will be distributed by the Partnership to investors through quarterly or special distributions. Although the Partnership will terminate no later than December 31, 2028, the value of the PIMs may be realized by the Partnership through repayment or sale as early as ten years from the dates of the closing of the permanent loans and the Partnership may realize the value of all its other investments within that time frame. Therefore, it is anticipated that dissolution of the Partnership could occur significantly prior to December 31, 2028. The Partnership's investments are not expected to be subject to seasonal fluctuations. However, the future performance of the Partnership will depend upon certain factors which cannot be predicted. In addition, any ultimate realization of the participation features of the PIMs will be subject to similar risks associated with equity real estate investments, including: reliance on the owner's operating skills, ability to maintain occupancy levels, control operating expenses, maintain the property and provide adequate insurance coverage; adverse changes in general economic conditions, adverse local conditions, and changes in governmental regulations, real estate zoning laws, or tax laws; and other circumstances over which the Partnership may have little or no control. The requirements for compliance with federal, state and local regulations to date have not had an adverse effect on the Partnership's operations, and the Partnership does not presently anticipate any adverse effect in the future. As of December 31, 1999 there were no personnel directly employed by the Partnership. ITEM 2. PROPERTIES None. ITEM 3. LEGAL PROCEEDINGS There are no material pending legal proceedings to which the Partnership is a party or to which any of its securities is the subject. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS None. PART II ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS There currently is no established trading market for the Units. The number of investors holding Units as of December 31, 1999 was approximately 13,200. One of the objectives of the Partnership is to provide quarterly distributions of cash flow generated by its investments in mortgages. The Partnership presently anticipates that future operations will continue to generate cash available for distribution. During 1999, the Partnership made special distributions consisting of principal proceeds from the Pope Building, Remington, Valley Manor and Cross Creek PIM Prepayments. During 1998, the Partnership made special distributions consisting primarily of principal proceeds from the Deering Place, Southland and Paddock Club Apartments PIM prepayments. The Partnership will make special distributions in the future as PIMs prepay or a sufficient amount of cash is available from MBS and PIM principal collections. The Partnership made distributions to its Partners during the two years ended December 31, 1999 and 1998 as follows: 1999 1998 Amount Per Unit Amount Per Unit Limited Partners $ 12,563,709 $ .84 $ 13,909,819 $ .93 General Partners 260,692 310,079 12,824,401 14,219,898 Special Distributions: Limited Partners 30,511,863 $ 2.04 20,789,946 $ 1.39 $ 43,336,264 $ 35,009,844 ITEM 6.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements including those concerning Management's expectations regarding the future financial performance and future events. These forward-looking statements involve significant risk and uncertainties, including those described herein. Actual results may differ materially from those anticipated by such forward-looking statements. Starting in 1997, the General Partners conducted an assessment of the Partnership's core internal and external computer information systems to understand the nature and extent of work required to make its systems Year 2000 ready. The Year 2000 readiness issue was concerned with the inability of computerized information systems to accurately calculate, store or use a date after 1999. The General Partners believed that a system failure or miscalculation could cause disruptions of operations. As a result of this concern, the General Partners, along with certain affiliates, upgraded their computer systems including their hardware and software so they would be Year 2000 ready. In addition, the General Partners surveyed the Partnership's material third-party service providers and significant vendors and received assurances that they were Year 2000 ready. The General Partners also developed contingency plans for all of their "mission-critical functions" to insure business continuity. As a result of these efforts and the efforts of third parties, the Year 2000 did not result in any disruption of activities to the Partnership. Liquidity and Capital Resources The most significant demands on the Partnership's liquidity are the regular quarterly distributions paid to investors of approximately $3.1 million. Funds used for the investor distributions are generated from interest income received on the PIMs, MBS, cash and short-term investments and the principal collections received on the PIMs and MBS. The Partnership funds a portion of the quarterly distribution from principal collections causing the capital resources of the Partnership to continually decrease. As a result of the decrease, the total cash inflows to the Partnership will also decrease, which will result in periodic adjustments to the distributions paid to investors. The General Partners periodically review the distribution rate to determine whether an adjustment is necessary based on projected future cash flows. In general, the General Partners try to set a distribution rate that provides for level quarterly distributions. Based on current projections the General Partners believe the Partnership will need to adjust the current distribution rate of $.21 per Unit per quarter commencing with the distribution to be paid in May 2000. The General Partners will determine the revised rate during the first quarter of 2000. In addition to providing insured or guaranteed monthly principal and basic interest payments, the Partnership's PIM investments also may provide additional income through its participation feature in the underlying properties if they operate successfully. The Partnership may receive a share in any operating cash flow that exceeds debt service obligations and capital needs or a share in any appreciation in value when the properties are sold or refinanced. However, this participation is neither guaranteed nor insured, and it is dependent upon whether property operations or its terminal value meet certain criteria. On February 25, 2000 the Partnership received a payoff on the Brookside Apartments PIM in the amount of $4,531,910. The Borrower defaulted on the first mortgage loan and Fannie Mae paid off the MBS upon maturity in February 2000. The Partnership anticipates a first quarter special distribution of $.31 per unit. The Partnership is pursuing the receipt of approximately $307,000 in additional income due from the borrower. At this time, it is uncertain if the Partnership will receive this income. During December 1999, the Partnership received prepayments on the Salishan, Saratoga, and Marina Shores Apartments PIMs, and the Patrician MBS. In addition to the principal proceeds of $14,666,235 from the Salishan PIM, the Partnership also received $146,662 of prepayment premium income and $311,650 of Shared Interest Income and Minimum Additional Income. The Partnership received $6,008,565 of principal proceeds from the Marina Shores PIM along with $176,679 of Shared Appreciation and prepayment premium income. The principal proceeds from the Saratoga PIM and the Patrician MBS prepayments were $6,204,895 and $7,830,263, respectively. The Partnership did not receive any additional interest on the Saratoga prepayment. On January 11, 2000, the Partnership paid a special distribution of $2.37 per Limited Partner interest from the principal proceeds, Shared Appreciation and prepayment premium received from these four payoffs. In October 1999 the Partnership received a repayment of the Valley Manor Apartments PIM of $4,425,993. The Partnership did not receive any Additional Interest as a result of this prepayment because the underlying property's appraised value did not exceed the threshold required to realize additional interest. In November 1999 the Partnership paid a special destribution of $.30 per Limited Partner interest from the Valley Manor proceeds. In February 1999, the Partnership received a payoff of the Pope Building PIM in the amount of $3,176,761. In addition, the Partnership received $703,860 of Shared Appreciation and prepayment premium income and $218,578 of Shared Income and Minimum Additional Interest upon the payoff of the underlying mortgage. During March 1999, the Partnership received a payoff of the Remington PIM in the amount of $12,199,298. The payoff was the result of a default on the underlying loan which resulted in the Partnership receiving all of the outstanding principal balance under the insurance feature of the PIM. However, due to the default the Partnership did not receive any participation income from this PIM. During May 1999, the Partnership paid a special distribution of $1.08 per Limited Partner interest from the principal proceeds received from the Remington and Pope Building PIMs and the Shared Appreciation and prepayment premium proceeds received from the Pope Building PIM. During January 1999, the Partnership paid a special distribution of $.66 per Limited Partner Interest from the principal proceeds and prepayment premium received from the Cross Creek PIM in 1998. The prepayment of the Cross Creek PIM remaining principal balance amounted to $9,414,586 with Additional Income (in lieu of a prepayment premium) of approximately $318,000 was received along with Shared Income of approximately $60,000. The Partnership made two special distributions during 1998. On July 27, 1998 and August 26, 1998, the Partnership received a partial prepayment and final prepayment of approximately $654,000, and $2,985,000, respectively, for the Deering Place Apartments PIM. In addition to the principal prepayment the Partnership received minimum additional interest and shared interest income of $90,195 and a prepayment premium of $268,638. The Partnership distributed the capital transaction proceeds from this prepayment to investors through a special distribution on September 18, 1998 in the amount of $.27 per Limited Partner interest. In January 1998, a $1.12 per Unit special distribution was made with the prepayment proceeds of the Paddock Club and Southland Station PIMs that were received in 1997. During the fourth quarter of 1997, the Partnership received the principal repayments totaling $15.2 million when those two properties were sold. In addition to the principal repayments, the Partnership received a total of $380,000 of accrued Additional Interest from both properties and $565,000 of Shared Appreciation Income on Southland Station and a $895,000 prepayment premium on Paddock Club. Most of the properties had stable operating results in 1999. High occupancy rates were maintained at more than half of the properties due to stable or improving markets. However, due to poor operating performance, the General Partners are closely monitoring the Wildflower apartments PIM property which is located in the thriving Las Vegas market. Wildflower has suffered a dramatic decline in occupancy to the mid-80% range at year-end that is not representative of the rest of the market. Wildflower, which offers only a basic apartment, does not compete successfully with the newer apartment properties, which have many amenities that have been built since the strong Las Vegas economy has fostered a tremendous construction boom. During the first five years, owners are prohibited from prepaying the first mortgage loans underlying the PIMs. During the second five years, owners may prepay the loans by incurring a prepayment penalty. The Partnership has the option to call certain PIMs by accelerating their maturity if they are not prepaid by the tenth year after permanent funding. The Partnership will determine the merits of exercising the call option for each PIM as economic conditions warrant. Such factors as the condition of the asset, local market conditions, the interest rate environment and availability of financing will affect those decisions. Assessment of Credit Risk The Partnership's investments in mortgages are guaranteed or insured by Fannie Mae, GNMA, FHLMC or HUD and therefore the certainty of their cash flows and the risk of material loss of the amounts invested depends on the creditworthiness of these entities. Fannie Mae is a federally chartered private corporation that guarantees obligations originated under its programs. FHLMC is a federally chartered corporation that guarantees obligations originated under its programs and is wholly-owned by the twelve Federal Home Loan Banks. These obligations are not guaranteed by the U.S. Government or the Federal Home Loan Bank Board. GNMA guarantees the full and timely payment of principal and basic interest on the securities it issues, which represent interests in pooled mortgages insured by HUD. Obligations insured by HUD, an agency of the U.S. Government, are backed by the full faith and credit of the U.S. Government. The Partnership includes in cash and cash equivalents approximately $38.9 million of commercial paper, which is issued by entities with a credit rating equal to one of the top two rating categories of a nationally recognized statistical rating organization. Interest Rate Risk The Partnership's primary market risk exposure is to interest rate risk, which can be defined as the exposure of the Partnership's net income, comprehensive income or financial condition to adverse movements in interest rates. At December 31, 1999, the Partnerships PIMs, PIMIs and MBS comprise the majority of the Partnership's assets. As such, decreases in interest rates may accelerate the prepayment of the Partnership's investments. The Partnership does not utilize any derivatives or other instruments to manage this risk as the Partnership plans to hold all of its investments to expected maturity. The Partnership monitors prepayments and considers prepayment trends, as well as distribution requirements of the Partnership, when setting regular dividend distribution policy. For MBS, the fund forecasts prepayments based on trends in similar securities as reported by statistical reporting entities such as Bloomberg. For PIMs and PIMIs, the Partnership incorporates prepayment assumptions into planning as individual properties notify the Partnership of the intent to prepay or as they mature. The table below provides information about the Company's financial instruments that are sensitive to changes in interest rates. For mortgage investments, the table presents principal cash flows and related weighted average interest rates by expected maturity dates. The expected maturity date is contractual maturity adjusted for expectations of prepayments.

(Amounts in thousands) 1999 1998 1997 Interest income on PIMs: Basic interest $ 6,325 $ 9,089 $ 10,887 Participation interest 1,666 865 3,710 Interest income on MBS 1,206 1,595 1,493 Other interest income 609 406 589 Partnership expenses (1,006) (1,219) (1,574) Amortization of prepaid fees and expenses (1,298) (1,636) (2,917) Net income $ 7,502 $ 9,100 $ 12,188 Net income decreased by approximately $1,598,000 during 1999 as compared to 1998. This decrease was due primarily to lower basic interest on PIMs and interest income on MBS in the amounts of approximately $2,764,000 and $389,000, respectively. This was partially offset by an increase in Participation interest of approximately $801,000 and decreases in asset management fees and amortization expense, in the amounts of approximately $215,000 and $338,000, respectively. The reduction in basic interest on PIMs is due to the payoff of the Remington, Pope Building and Valley Manor PIMs in 1999 and the payoffs of the Deering Place and Cross Creek PIMs in 1998. The decrease in MBS interest income was due to the on-going prepayment of the Partnership's single-family MBS. The increase in participation interest on PIMs was due primarily to the receipt of $922,000, $458,000 and $177,000 of participation interest from the Pope Building, Salishan and Marina Shores PIM prepayments as compared to the $359,000 and $378,000 received in 1998 from the Deering Place and Cross Creek PIM payoffs, respectively. Also, asset management fees decreased during 1999 as compared to 1998 due to the prepayments and principal collections reducing the Partnership's mortgage investments. Amortization expense was greater in 1998 as a result of the full amortization of the remaining prepaid fees and expenses of the Deering Place and Cross Creek PIMs and the Patrician multi-family MBS in 1998 exceeding the amount of amortization resulting from the PIM prepayments occurring in 1999. Net income decreased by approximately $3,088,000 during 1998 as compared to 1997. The decrease was primarily due to lower basic interest and participation interest. The decrease in basic interest of approximately $1,798,000 was a result of the Deering Place and Cross Creek PIM prepayments during 1998, and the prepayments of the Rock Creek, Silver Springs, Hampton Ridge, Southland Station and Paddock Club PIM's during 1997 and the Patrician PIM converting to a non-participating insured mortgage during the fourth quarter of 1997. Participation interest declined by approximately $2,845,000 as a result of the significant level of PIM prepayments in 1997 mentioned above exceeding the level of participation interest received when the Deering Place and Crosscreek PIM prepayments occurred in 1998. Other interest income decreased in 1998 as compared to 1997 due to lower average short-term investment balances during 1998 when compared to 1997. Amortization expense decreased for the twelve month period ending 1998 as compared to the same period in 1997 as a result of the Partnership fully amortizing the costs associated with the PIMs that were prepaid in 1997. The decrease in Partnership expenses was due primarily to lower asset management fees resulting from the prepayments of the Deering Place and Crosscreek PIMs in 1998 and the Rock Creek, Silver Springs, Hampton Ridge, Paddock Club and Southland PIMs in 1997. In addition, lower transfer agent costs were incurred in 1998 and a rebate was received for expense reimbursements related to 1997 during the second quarter of 1998. ITEM 8.

KRUPP INSURED MORTGAGE LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS, Continued A. Organization Krupp Insured Mortgage Limited Partnership (the "Partnership") was formed on March 21, 1988 by filing a Certificate of Limited Partnership in The Commonwealth of Massachusetts. The Partnership was organized for the purpose of investing in multi-family loans and mortgage backed securities. The Partnership issued all of the General Partner Interests to two General Partners in exchange for capital contributions aggregating $3,000. Krupp Plus Corporation and Mortgage Services Partners Limited Partnership are the General Partners of the Partnership and Krupp Depositary Corporation is the Corporate Limited Partner. Except under certain limited circumstances upon termination of the Partnership, the General Partners are not required to make any additional capital contributions. The Partnership terminates on December 31, 2028, unless terminated earlier upon the occurrence of certain events as set forth in the Partnership Agreement. The Partnership commenced the public offering of Units on July 22, 1988 and completed its public offering on May 23, 1990 having sold 14,956,696 Units for $298,678,321 net of purchase volume discounts of $457,599. In addition, Krupp Depository owns one hundred units. B. Significant Accounting Policies The Partnership uses the following accounting policies for financial reporting purposes, which may differ in certain respects from those used for federal income tax purposes (see Note G): MBS The Partnership, in accordance with Financial Accounting Standards Board's Special Report on Statement 115, "Accounting for Certain Investments in Debt and Equity Securities" (FAS 115), classifies its MBS portfolio as available-for-sale. As such the Partnership carries its MBS at fair market value and reflects any unrealized gains (losses) as a separate component of Partners' Equity. The Partnership amortizes purchase premiums or discounts over the life of the underlying mortgages using the effective interest method. Effective January 1, 1998, the Partnership adopted Statement of Financial Accounting Standards No. 130, 'Reporting Comprehensive Income' (FAS 130). FAS 130 established standards for reporting and displaying comprehensive income and its components. FAS 130 requires comprehensive income and its components, as recognized under accounting standards, to be displayed in a financial statement with the same prominence as other financial statements, if material. Accordingly, unrealized gains (losses) on the Partnership's available-for sale securities have been included in other comprehensive income. PIMs The Partnership accounts for its MBS portion of a PIM in accordance with FAS 115 under the classification of held to maturity. The Partnership carries the Government National Mortgage Association (GNMA) or Fannie Mae MBS at amortized cost. The insured mortgage portion of its Federal Housing Administration (FHA) PIM is carried at amortized cost. The Partnership holds this FHA insured mortgage at amortized cost since the loan is fully insured by the FHA. Basic interest on PIMs is recognized based on the stated rate of the FHA mortgage loan (less the servicer's fee) or the stated coupon rate of the GNMA or Fannie Mae MBS. Participation interest is recognized as earned and when deemed collectible by the Partnership. Continued B. Significant Accounting Policies, continued Cash and Cash Equivalents The Partnership includes all short-term investments with maturities of three months or less from the date of acquisition in cash and cash equivalents. The Partnership invests its cash primarily in commercial paper and money market funds with a commercial bank and has not experienced any loss to date on its invested cash. Prepaid Fees and Expenses Prepaid fees and expenses represent prepaid acquisition fees, expenses and prepaid participation servicing fees paid for the acquisition and servicing of PIMs. The Partnership amortizes prepaid acquisition fees and expenses using a method that approximates the effective interest method over a period of ten to twelve years, which represents the actual maturity or anticipated repayment of the underlying mortgage. Acquisition expenses incurred on potential acquisitions which were not consummated were charged to operations. The Partnership amortizes prepaid participation servicing fees using a method that approximates the effective interest method over a ten-year period beginning at final endorsement of the loan if a Department of Housing and Urban Development ("HUD") loan or GNMA loan and at closing if a Fannie Mae loan. Income Taxes The Partnership is not liable for federal or state income taxes as Partnership income is allocated to the partners for income tax purposes. In the event that the Partnership's tax returns are examined by the Internal Revenue Service or state taxing authority and the examination results in a change in Partnership taxable income, such change will be reported to the partners. Estimates and Assumptions The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, contingent assets and liabilities and revenues and expenses during the period. Actual results could differ from those estimates. C. PIMs At December 31, 1999 and 1998, the Partnership had investments in six PIMs and twelve PIMs, respectively. The Partnership's PIMs consist of (a) a GNMA or Fannie Mae MBS representing the securitized first mortgage loan on the underlying property or a sole participation interest in the mortgage loan originated under HUD's FHA lending program (collectively the "insured mortgages"), and (b) participation interests in the revenue stream and appreciation of the underlying property above specified base levels. The borrower conveys these participation features to the Partnership generally through a subordinated promissory note and mortgage (the "Agreement"). The Partnership receives guaranteed monthly payments of principal and interest on the GNMA and Fannie Mae MBS, and HUD insures the FHA mortgage loan. The borrower usually cannot prepay the first mortgage loan during the first five years and may prepay the first mortgage loan thereafter subject to a 9% prepayment premium in years six through nine, a 1% prepayment premium in year ten and no prepayment premium thereafter. The Partnership may receive interest related to its participation interests in the underlying property, however, these amounts are neither insured nor guaranteed. Generally, the participation features consist of the following: (i) "Minimum Additional Interest" which is at the rate of .5% to 1% per annum calculated on the unpaid principal balance of the first mortgage on the underlying property, (ii) "Shared Income Interest" which is 25% to 35% of the monthly gross rental income generated by the underlying property in excess of a specified base, but only to the extent that it exceeds the amount of Minimum Additional Interest earned Continued C. PIMs, continued during such month, (iii) "Shared Appreciation Interest" which is 25% to 35% of any increase in the value of the underlying property in excess of a specified base. Payment of participation interest from the operations of the property is limited in any year to 50% of net revenue or surplus cash as defined by Fannie Mae or HUD, respectively. The aggregate amount of Minimum Additional Interest, Shared Income Interest and Shared Appreciation Interest payable by the underlying borrower on the maturity date generally cannot exceed 50% of any increase in value of the property. However, generally any net proceeds from the sale or refinancing of the property will be available to satisfy any accrued but unpaid Shared Income or Minimum Additional Interest. Shared Appreciation Interest is payable when one of the following occurs: (1) the sale of the underlying property to an unrelated third party on a date which is later than five years from the date of the Agreement, (2) the maturity date or accelerated maturity date of the Agreement, or (3) prepayment of amounts due under the Agreement and the insured mortgage. The Partnership, upon giving twelve months written notice, can accelerate the maturity date of the Agreement to a date not earlier than ten years from the date of the Agreement for (a) the payment of all participation interest due under the Agreement as of the accelerated maturity date, or (b) the payment of all participation interest due under the Agreement plus all amounts due on the first mortgage note on the property. During December 1999, the Partnership received prepayments on the Salishan, Saratoga, and Marina Shores Apartments PIMs, and the Patrician MBS. In addition to the principal proceeds from the Salishan PIM of $14,666,235, the Partnership received $146,662 of prepayment premium income and $311,650 of Shared Interest Income and Minimum Additional Income. The Partnership received $6,008,565 of principal proceeds from the Marina Shores PIM along with $176,679 of Shared Appreciation and prepayment premium income. The principal proceeds from the Saratoga PIM and the Patrician MBS prepayments were $6,204,895 and $7,830,263, respectively. The Partnership did not receive any additional interest on the Saratoga prepayment. On January 11, 2000, the Partnership paid a special distribution of $2.37 per Limited Partner interest from these four payoffs. During November 1999, the Partnership paid a special distribution of $.30 per Limited Partner interest from the principal proceeds received from the Valley Manor PIM prepayment of $4,425,993. The Partnership did not receive any participation income from this PIM prepayment. During May 1999, the Partnership paid a special distribution of $1.08 per Limited Partner interest from the principal proceeds, Shared Appreciation and prepayment proceeds received from the Remington and Pope Building PIMs (see below). During March 1999, the Partnership received a payoff of the Remington PIM in the amount of $12,199,298. The payoff was the result of a default on the underlying loan which resulted in the Partnership receiving all of the outstanding principal balance under the insurance feature of the PIM. However, due to the default the Partnership did not receive any participation income from this PIM. During February 1999, the Partnership received a payoff of the Pope Building PIM in the amount of $3,176,761. In addition, the Partnership received $703,860 of Shared Appreciation and prepayment premium income and $218,578 of Shared Income and Minimum Additional Interest upon the payoff of the underlying mortgage. During January 1999, the Partnership paid a special distribution of $.66 per Limited Partner interest from the principal proceeds and prepayment premium received from the Cross Creek PIM during 1998. On November 16, 1998, the Partnership received a prepayment of the Cross Creek PIM in the amount of approximately $9,414,586. Additional interest in lieu of a prepayment penalty of approximately $318,000 along with shared interest income of approximately $60,000 was also received during 1998. Continued C. PIMs, continued On July 27, 1998 and August 26, 1998, the Partnership received a partial prepayment and final prepayment of approximately $654,000, and $2,985,000, respectively, for the Deering Place Apartments PIM. In addition to the principal repayment, the Partnership received minimum additional interest and shared interest income of $90,195 and a prepayment penalty of $268,638. The Partnership distributed the capital transaction proceeds from this prepayment to investors through a special distribution on September 18, 1998 in the amount of $.27 per Limited Partner interest.

The basis of the Partnership's assets for financial reporting purposes is less than its tax basis by approximately $2,634,000 and $3,823,000 at December 31, 1999 and 1998, respectively. The basis of the Partnership's liabilities for financial reporting purposes are less than its tax basis by approximately $265,000 and $0 at December 31, 1999 and 1998, respectively. H. Fair Value Disclosure of Financial Instruments The Partnership uses the following methods and assumptions to estimate the fair value of each class of financial instruments: Cash and cash equivalents The carrying amount approximates fair value due to the short maturity of those instruments. MBS The Partnership estimates the fair value of MBS based on quoted market prices. Based on the estimated fair value determined using these methods and assumptions, the Partnership's investments in MBS had gross unrealized gains and losses of approximately $140,000 and $136,000 at December 31, 1999 and $645,000 and $0 at December 31, 1998. Continued H. Fair Value Disclosure of Financial Instruments, continued PIMs There is no active trading market for these investments. Management estimates the fair value of the PIMs using quoted market prices of MBS having the same stated coupon rate. Management does not include any participation income in the Partnership's estimated fair value arising from appreciation of the properties, because Management does not believe it can predict the time of realization of the feature with any certainty. Based on the estimated fair value determined using these methods and assumptions, the Partnership's investments in PIMs had gross unrealized gains and losses of approximately $168,000 and $311,000, respectively, at December 31, 1999, and gross unrealized gains of approximately $2,527,000 at December 31, 1998. At December 31, 1999 and 1998, the estimated fair values of the Partnership's financial instruments are as follows: (Amounts in thousands) 1999 1998 Fair Carrying Fair Carrying Value Value Value Value Cash and cash equivalents $ 39,435 $ 39,435 $ 15,117 $ 15,117 MBS 7,460 7,460 18,807 18,807 PIMS 51,247 51,390 101,478 98,951 $ 98,142 $ 98,285 $135,402 $132,875 I. Subsequent Event On February 25, 2000 the Partnership received a payoff on the Brookside Apartments PIM in the amount of $4,531,910. The Borrower defaulted on the first mortgage loan and Fannie Mae paid off the MBS upon maturity in February 2000. The Partnership anticipates a first quarter special distribution of $.31 per unit. The Partnership is pursuing the receipt of approximately $307,000 in additional income due from the borrower. At this time, it is uncertain if the Partnership will receive this income.
