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"), Federal National Mortgage Association ("FNMA") 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 FNMA or the Federal Home Loan Mortgage Corporation ("FHLMC"). FNMA and FHLMC guarantee the principal and basic interest of the Partnership's FNMA and FHLMC MBS, respectively. Prior to May 23, 1995 the Partnership could reinvest or commit for reinvestment principal proceeds or other realization of the mortgages in new mortgages. Subsequently, proceeds received from prepayments or other realizations of mortgage assets have been and will continue to be distributed by the Partnership to investors through quarterly or possibly 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 regula- tions, 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 adverse effect in the future. As of December 31, 1997, 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, 1997 was approximately 14,600. 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 1997, the Partnership made special distributions consisting primarily of principal proceeds from the Rock Creek, Silver Spring, and Hampton Ridge 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. During 1996, the Partnership made a special distribution consisting primarily of principal proceeds from the Water View and Tarnhill Apartments PIM prepayments. The Partnership made distributions to its Partners during the two years ended December 31, 1997 as follows: -4- 1997 1996 Amount Per Unit Amount Per Unit Limited Partners $ 17,948,156 $1.20 $17,948,153 $1.20 General Partners 386,086 431,074 18,334,242 18,379,227 Special Distributions Limited Partners $ 28,717,048 $1.92 25,426,553 $1.70 $ 47,051,290 $43,805,780 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 risks and uncertainties, including those described herein. Actual results may differ materially from those anticipated by such forward-looking statements. Liquidity and Capital Resources The most significant demands on the Partnership's liquidity are regular quarterly distributions paid to investors of approximately $4.5 million. Funds used for 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 distribution from principal collections and, as a result, the capital resources of the Partnership will continually decrease. As a result of this 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 to the distribution rate 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 of cash available for distribution. To the extent quarterly distributions do not fully utilize the cash available for distribution and cash balances increase, the General Partners may adjust the distribution rate or distribute such funds through a special distribution. Four properties with loans underlying the Partnership's PIM investments were either sold or refinanced during 1997. A fifth PIM was converted to an insured mortgage when the participation feature was released. A sixth PIM was paid off after the borrower defaulted on its first mortgage obligations. One property that was sold had increased in value since the Partnership made its initial investment in the PIM and paid Shared Appreciation Interest based on that increase in value. The other three properties that were sold or refinanced did not increase in value sufficiently to reach the threshold necessary for the Partnership to earn Shared Appreciation Interest when they were sold or refinanced. However, the payoff transactions on two of these three properties generated enough value so that the Partnership received all accrued Additional Interest earned on property operations in prior years and full prepayment penalties equal to 9% of the principal repayment in lieu of Shared Appreciation Interest. The General Partners accepted negotiated settlements on the other two properties that were sold or refinanced because of value constraints. During the first quarter of 1997, the Partnership received the full $11.1 million principal repayment of the Rock Creek Springs PIM. Fannie Mae, as the guarantor of the MBS underlying the Partnership's PIM, exercised its right to retire the security when the first mortgage went into default. The Partnership made a $.75 per unit special distribution on March 21, 1997 with the proceeds from the PIM repayment. During the second quarter of 1997, the Partnership received a $7.2 million principal repayment of the Silver Spring PIM when the property was sold. In addition to the principal repayment, the Partnership received $41,000 of accrued Additional Interest and a $652,000 prepayment penalty. The Partnership made a $.53 per unit special distribution on May 23, 1997 with the proceeds of the PIM repayment. In addition during the quarter, The Patrician was sold, and the value of the property failed to appreciate beyond the threshold above which the Partnership would have earned Shared Appreciation Interest. In order to facilitate the sale transaction, the General Partners agreed to the assumption of the first mortgage loan by the purchaser and required a $100,000 settlement to release the participation features of the PIM and convert its investment into an insured mortgage. -6- During the fourth quarter of 1997, the Partnership received a $9.1 million principal repayment of the Hampton Ridge PIM when the owner refinanced the property. In addition to the principal repayment, the Partnership received $249,000 of accrued Additional Interest and a $508,000 prepayment penalty. The value of the property had not increased beyond the base threshold above which the Partnership would earn any Shared Appreciation Interest. Consequently, the General Partners accepted the repayment of the loan in 1997 while the interest rate environment facilitated a favorable refinancing of the property and agreed to a 5% prepayment penalty. The Partnership made a $.64 per unit special distribution on November 21, 1997 with the proceeds of the PIM repayment. During the fourth quarter of 1997, the Partnership also received the principal repayments of the Paddock Club and Southland Station PIM's together totaling $15.2 million when those 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 Interest on Southland Station and a $895,000 prepayment penalty on Paddock Club. The Partnership paid a $1.12 per unit special distribution in January 1998 with the proceeds of these two PIM repayments. During 1996 and 1997, the Partnership received significant prepayments on its PIMs. Due to this, the General Partners reviewed the Partnership's liquidity needs and determined that the regular distribution rate should be adjusted to $.84 per Unit per year (approximately $12.5 million per year and $3.14 million per quarter) commencing with the May 1998 distribution. The General Partners expect to periodically adjust the distribution rate as mortgage proceeds are received and subsequently distributed to the Limited Partners while also maintaining sufficient liquidity to meet the Partnership's anticipated needs. The General Partners will continue to monitor the appropriateness of this distribution rate in the future and will adjust it as necessary. For the first five years of the PIMs the borrowers are prohibited from repaying. For the second five years, the borrower can repay the loans incurring a prepayment penalty. The Partnership has the option to call certain PIMs by accelerating their maturity, if the loans 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, interest rates and available financing will have an impact on this decision. Assessment of Credit Risk The Partnership's investments in mortgages are guaranteed or insured by FNMA, 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. FNMA 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. -7- Operations The following discussion relates to the operation of the Partnership during the years ended December 31, 1997, 1996 and 1995. (Amounts in thousands) 1997 1996 1995 Interest income on PIMs: Base interest $10,887 $ 12,953 $14,555 Participation interest 3,710 1,176 677 Interest income on MBS 1,493 1,498 1,778 Other interest income 589 413 316 Partnership expenses (1,574) (1,655) (2,073) Amortization of prepaid fees and expenses (2,917) (3,013) (1,983) Net income $12,188 $11,372 $13,270 Net income increased during 1997 as compared to 1996 by approximately $816,000 due primarily to prepayment penalty income and participation interest received from the Hampton Ridge, Silver Spring, Paddock Club and Southland Station Apartment PIMs. As a result of the four above mentioned repayments and the Rock Creek PIM prepayment by FNMA, base interest decreased approximately $2,066,000 or 16%. An increase in Participation Income of $2,534,000 was primarily a result of receiving shared appreciation income, accrued additional interest and prepayment penalties from the prepayment of the Silver Springs, Hampton Ridge, Southland and Paddock Club Apartment PIMs totaling $3,389,000 and $321,000 of additional interest from five of the Partnerships other PIMs. Other interest income increased in 1997 as compared to 1996 due to the short-term investment of the proceeds from the prepayments until such funds were ultimately distributed to the investors. Partnership expenses have decreased when comparing 1997 to 1996 and 1996 to 1995, due primarily to lower asset management fees. Net income decreased during 1996 as compared to 1995 by approximately $1,898,000 due primarily to a reduction in base interest in PIMs as a result of prepayments of the Water View and Tarnhill Apartments PIMs and interest rate reductions on the Crosscreek Apartments and Remington Place Apartments PIMs. Interest income on MBS decreased $280,000 in 1996 as compared to 1995, because principal collections reduced the outstanding principal balance of the Partnership s MBS investments. These items were offset by an increase in participation income of $499,000 which was primarily the result of receiving shared appreciation income from the prepayment of the Tarnhill Apartments PIM of $983,000, net of a decrease in shared income and minimal additional interest recorded in 1996 as compared to 1995 of $484,000. Other interest income increased in 1996 as compared to 1995 due to the short-term investment of the proceeds from the prepayments until such funds were ultimately distributed to the investors. Amortization expense increased for 1996 as compared to 1995 because the Partnership fully amortized the remaining balances of prepaid fees and expenses associated with the Water View and Tarnhill Apartments PIM.

KRUPP INSURED MORTGAGE LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS 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 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 14,956,796 Units for $298,678,321 net of purchase volume discounts of $457,599. 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. 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 Federal National Mortgage Association ( FNMA ) MBS at amortized cost. The Federal Housing Administration PIMs are carried at amortized cost unless the General Partners of the Partnership believe there is an impairment in value, in which case a valuation allowance would be established in accordance with F-10 Financial Accounting Standards No. 114, Accounting by Creditors for Impairment of a Loan, and Financial Accounting Standard No. 118, Accounting by Creditors for Impairment of a Loan - Income Recognition and Disclosures. Basic interest on PIMs is recognized based on the stated rate of the Federal Housing Administration ("FHA") mortgage loan (less the servicer's fee) or the stated coupon rate of the GNMA or FNMA 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 FNMA 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 The Partnership has investments in 14 PIMs. The Partnership's PIMs consist of (a) a GNMA or FNMA 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"). F-12 KRUPP INSURED MORTGAGE LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS, Continued C.PIMs, continued The Partnership receives guaranteed monthly payments of principal and interest on the GNMA and FNMA MBS, and HUD insures the FHA mortgage loan and the mortgage loan underlying the GNMA MBS. 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 penalty in years six through nine, a 1% prepayment penalty in year ten and no prepayment penalty 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% per annum calculated on the unpaid principal balance of the first mortgage on the underlying property, (ii) "Shared Income Interest" which is 25% 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 during such month, (iii) "Shared Appreciation Interest" which is 25% 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 FNMA 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. Under the Agreement, 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. On February 25, 1997, the Partnership received a prepayment of the Rock Creek Apartments PIM. The Partnership received the outstanding principal balance of $11,139,968 plus outstanding interest. F-13 KRUPP INSURED MORTGAGE LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS, Continued The Partnership did not receive any prepayment penalty or participation income from this PIM. The Borrower of the Rock Creek Springs PIM defaulted on its debt service obligation during the third quarter of 1996. FNMA, the guarantor of the MBS portion of the PIM, was unable to negotiate a workout plan with the borrower and exercised its option to repay the MBS in February 1997 and pursue a foreclosure. On March 21, 1997, the Partnership made a special distribution of $.75 per Limited Partner interest with the proceeds from the Rock Creek payoff. Continued C. PIMs, continued On April 25, 1997, the Partnership received a prepayment of the Silver Springs PIM. The Partnership received the outstanding principal balance of $7,249,479 plus outstanding interest on April 25, 1997, while on March 31,1997,the Partnership had received a prepayment penalty of $652,453 and Minimum Additional and Shared Income Interest of $41,173. On May 23,1997 the Partnership made a special distribution of $.53 per unit to the Limited Partners from the proceeds of the Silver Springs PIM prepayment. During the second quarter of 1997, the Partnership received a $100,000 payment for all additional interest earned on the Patrician Apartments PIM through the date of discharge. The Partnership then converted the investment in the PIM to a multi-family insured mortgage. On October 27, 1997, the Partnership received a prepayment of the Hampton Ridge Apartments PIM. The Partnership received the outstanding principal balance of $9,067,437 plus outstanding interest. The Partnership received a prepayment penalty of approximately $508,000 in addition to participation income of approximately $249,000. On November 21, 1997, the Partnership made a special distribution of $.64 per unit to the Limited Partners from the proceeds of the Hampton Ridge PIM prepayment. During December, 1997, the Partnership received prepayments of the Southland Station Apartments and Paddock Club Apartments PIMs, respectively. The Partnership received the outstanding principal balances of $5,254,302 and $9,942,697 on the Southland Apartments and Paddock Club Apartments PIMs, respectively. The Partnership received shared appreciation and prepayment penalties of $565,195 and $894,843 from the prepayment of the Southland Apartments and Paddock Club Apartments PIMs, respectively. In addition, the Partnership received participation income of $83,441 and $296,799 from the Southland and Paddock Club Apartment PIMs, respectively. The Partnership made a special distribution of $1.12 per Limited Partner interest with the proceeds from the outstanding principal proceeds and the prepayment penalties during January 1998. On February 16, 1996, the Partnership received a prepayment of the Water View Apartments PIM. The Partnership received the outstanding principal balance of $16,651,149 plus outstanding interest. The Partnership did not receive any prepayment penalty or participation income from this PIM. During1995, the operating performance of Water View Apartments declined due to insufficient levels of occupancy and higher maintenance and repair expenses due to vandalism. As a result, the borrower went into default on the underlying loan. Normally, a loan like this would eventually be recovered through an insurance claim process. However, the Partnership was able to receive its insured proceeds on this loan earlier than anticipated due toBear Stearn s assumption of the underlying insured mortgage. On February 29, 1996, the Partnership received a prepayment of the Tarnhill PIM. The Partnership received the outstanding principal balance of $7,483,000, Shared Appreciation Interest of $982,845 and Minimum Additional and Shared Income Interest of $223,728. During August 1996, the Partnership made a special distribution of $1.70 per unit to the Limited Partners from the proceeds of the Water View Apartments and Tarnhill PIM prepayments. Continued C.

Fair Value Disclosure of Financial InstrumentsF-18 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. 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 Trust's investments in PIMs had gross unrealized gains of approximately $2,596,000 at December 31, 1997, and gross unrealized gains and losses of approximately $1,506,000 and $372,000, respectively, at December 31, 1996.
