Actual results could differ materially from those projected in the forward looking statements as a result of a number of factors, including those identified herein. ITEM 1. BUSINESS On December 20, 1985, The Krupp Corporation and The Krupp Company Limited Partnership-IV (the "General Partners") formed Krupp Insured Plus Limited Partnership (the "Partnership"), a Massachusetts Limited Partnership. The Partnership raised approximately $149 million through a public offering of limited partner interests evidenced by units of depositary receipts ("Units") and used the net proceeds primarily to acquire participating insured mortgages ("PIMs") and mortgage backed securities ("MBS"). The Partnership considers itself to be engaged in the industry segment of investment in mortgages. The Partnership's investments in PIMs consist of a securitized multi-family first mortgage loan or a sole participation interest in a Department of Housing and Urban Development ("HUD") multi-family insured first mortgage loan, and participation interests in the current revenue stream of the mortgaged property and any increase in the mortgaged property's value above certain specified base levels. The Partnership provided the funds for the first mortgage loan made to the borrower by acquiring either a securitized first mortgage loan ("MBS"), originated under the lending program of Fannie Mae or a sole participation interest in a first mortgage loan originated under the Federal Housing Administration ("FHA") lending program (collectively the "insured mortgages"). The Partnership receives the participation interests in the mortgaged property as additional consideration for providing the funds for the first mortgage loan and accepting a below market interest rate on the insured mortgage. The borrower conveyed the participation interests to the Partnership through either a subordinated promissory note and mortgage or a shared income and appreciation agreement. Fannie Mae guarantees the principal and interest payments for the Fannie Mae insured mortgage. HUD insures the first mortgage loan originated under the FHA lending program. The participation interests conveyed to the Partnership by the borrower are neither insured nor guaranteed. The Partnership also has investments in MBS backed by single-family or multi-family mortgage loans issued or originated by the Government National Mortgage Association ("GNMA"), Fannie Mae or the Federal Home Loan Mortgage Corporation ("FHLMC"). Fannie Mae and FHLMC guarantee the principal and interest on the Fannie Mae and FHLMC MBS, respectively. GNMA guarantees the timely payment of principal and interest on its MBS and HUD insures the pooled mortgage loans underlying the GNMA MBS. Although the Partnership will terminate no later than December 31, 2025 the Partnership anticipates realizing the value of the PIMs through repayment well before this date. Therefore, dissolution of the Partnership should occur significantly prior to December 31, 2025. The Partnership's investments are not subject to seasonal fluctuations. However, the realization of the participation features of the PIMs are 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 Partnership anticipates that there will be sufficient cash flow from the mortgages to meet cash requirements. To the extent that the Partnership's cash flow is insufficient to meet the Partnership's operating expenses and liabilities, it will be necessary for the Partnership to obtain additional funds by liquidating its investment in one or more mortgages or by borrowing. The Partnership may borrow money on an unsecured or secured basis to further the purposes of the Partnership. The Partnership may pledge mortgages as security for any permitted borrowing. The Partnership, under some circumstances, may borrow funds from any general partner or an affiliate of any general partner. However, the transaction must include interest rates and other finance charges and fees not in excess of the amounts that are charged by unaffiliated lenders for comparable loans and must satisfy other conditions specified in the partnership agreement. The Partnership has not borrowed any funds during the past and does not intend to do so in the future. The FHA coinsurance loan program under Section 221(d)(4) of the National Housing Act provides for loans with 40 year terms. However, this program allows for a call option at any time after ten years, upon one year's notice. The subordinated promissory note and subordinated mortgage of the PIM provides for acceleration of maturity at the earlier of the sale of the underlying property or the call date, typically expected to be a date ten years after the date of final endorsement for mortgage insurance. From time to time, the Partnership expects that it may realize the principal and participation in residual value, if any, of its mortgages before maturity. It was expected that the mortgages would be repaid after a period of ownership of approximately ten years from the dates of the closings of permanent loans. Realization of the value of mortgages, however, have been made at earlier and later dates. 2 <Page> The Partnership will not underwrite securities of other issuers, offer securities in exchange for property, invest in securities of other issuers for the purpose of exercising control or issue senior securities, and the Partnership has not engaged in any of these activities during the past. The Partnership has not repurchased or reacquired any of the partner interests from partners or units from unit holders in the past and does not intend to do so in the future. The Partnership may not make loans to any general partner or any affiliate of any general partner and will not make loans to any other persons, other than mortgage investments of the type described above. The requirements for compliance with federal, state and local regulations to date have not adversely effected the Partnership's operations and the Partnership does not presently anticipate adverse effects in the future. As of December 31, 2001, 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 investments 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, 2001 was approximately 5,500. 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. Adjustments may be made to the distribution rate in the future due to the realization and payout of the existing mortgages. During August 2001, the Partnership made a special distribution of $1.25 per Limited Partner interest from the principal proceeds and prepayment premium received from the Boulders Apartments MBS. During November 2000, the Partnership made a special distribution of $.33 per Limited Partner interest from the principal proceeds and prepayment premium received from the Chateau Bijou MBS. During January 2000, the Partnership made a special distribution of $1.30 per Limited Partner interest from the principal proceeds and Shared Appreciation Interest from the LaCosta PIM. The Partnership may make special distributions in the future if MBS or PIMs prepay or a sufficient amount of cash is available from MBS and PIM principal collections. The Partnership made the following distributions, in quarterly installments, and special distributions, to its Partners during the two years ended December 31, 2001 and 2000: <Table> <Caption> 2001 2000 -------------------------- ---------------------------- Amount Per Unit Amount Per Unit ------------ -------- ------------ -------- Distributions: Limited Partners $ 3,000,040 $ .40 $ 5,700,076 $ .76 General Partners 78,220 - 97,014 - ------------ ------------ 3,078,260 5,797,090 ------------ ------------ Special Distributions: Limited Partners 9,375,124 $ 1.25 12,225,162 $ 1.63 ------------ ------------ Total Distributions $ 12,453,384 $ 18,022,252 ============ ============ </Table> 3 <Page> ITEM 6.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Certain statements in this Management's Discussion and Analysis of Financial Condition and Results of Operations and elsewhere in this Form 10-K constitute "forward-looking statements" within the meaning of the Federal Private Securities Litigation Reform Act of 1995. These forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the Partnership's actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by these forward-looking statements. These factors include, among other things, federal, state or local regulations; adverse changes in general economic or local conditions; prepayments of mortgages; failure of borrowers to pay participation interests due to poor operating results at properties underlying the mortgages; uninsured losses and potential conflicts of interest between the Partnership and its Affiliates, including the General Partners. LIQUIDITY AND CAPITAL RESOURCES At December 31, 2001 the Partnership had liquidity consisting of cash and cash equivalents of approximately $1.4 million as well as the cash flow provided by its investments in the PIMs and MBS. The Partnership anticipates that these sources will be adequate to provide the Partnership with sufficient liquidity to meet its obligations as well as to provide distributions to its investors. The most significant demand on the Partnership's liquidity is quarterly distributions paid to investors, which are approximately $750,000 per quarter. Funds for the quarterly distributions come from the monthly principal and interest payments received on the PIMs and MBS, the principal prepayments of the PIMs and MBS, interest earned on the Partnership's cash and cash equivalents and cash reserves. The portion of distributions attributable to the principal collections and cash reserves reduces the capital resources of the Partnership. As the capital resources of the Partnership decrease, the total cash flows to the Partnership also will decrease and over time 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 expect that the Partnership will reduce the distribution rate of $.10 per Limited Partner interest per quarter to $.06 per Limited Partner interest per quarter with the May 2002 distribution. 4 <Page> In addition to providing insured or guaranteed monthly principal and basic interest payments, the Partnership's investments in the PIMs also may provide additional income through a participation interest in the underlying properties. However, this payment is neither guaranteed nor insured and depends on the successful operations of the underlying properties. The Partnership received a prepayment of the Royal Palm Place PIM. On January 2, 2002, the Partnership received $378,480 of Shared Appreciation Interest and $121,490 of Minimum Additional Interest. On February 27, 2002 the Partnership received $5,563,531 representing the principal proceeds on the first mortgage. The Partnership has declared a special distribution of $.80 per Limited Partner interest consisting of Shared Appreciation Interest and prepayment proceeds which will be paid in the first quarter of 2002. The Partnership received a payoff of the Boulders Apartments MBS on July 9, 2001 for $9,045,042. The Partnership also received a prepayment premium of $306,000 from this payoff. On August 17, 2001, the Partnership paid a special distribution of $1.25 per Limited Partner interest from the proceeds received. The Partnership received a payoff from the Chateau Bijou MBS on September 19, 2000 for $2,266,064. During October the Partnership received a 9% prepayment premium of $203,946 from this payoff. The Partnership paid a special distribution in November of $.33 per Limited Partner interest from the proceeds received. In December 1999, the Partnership received a prepayment in the amount of $9,746,923 representing the outstanding principal balance due on the La Costa PIM. The Borrower defaulted on the first mortgage loan underlying the PIM in June of 1999. The Partnership continued to receive its full principal and interest payments until the default was resolved as GNMA guaranteed those payments to the Partnership. The Partnership did not receive any participation interest as a result of this default. However, the Partnership received $10,000 from the Borrower to release the Subordinated Promissory Note. This payment was classified as Shared Appreciation Interest. On January 11, 2000, the Partnership paid a special distribution to the investors of $1.30 per Limited Partner interest. With the payoff of the Royal Palm Place PIM in January, 2002, the Partnership's only remaining PIM investment is backed by the first mortgage loan on Vista Montana. Presently, the General Partners do not expect Vista Montana to pay the Partnership any participation interest or to be sold or refinanced during 2002. However, if favorable market conditions provide the borrower an opportunity to sell the property, there are no contractual obligations remaining that would prevent a prepayment of the underlying first mortgage. Vista Montana operates under a long-term restructure program. The Partnership agreed in 1993 to change the original participation terms and to permanently reduce the rate on the first mortgage loan to 7.375% per annum when construction was significantly delayed. The borrower also raised additional equity at the time of the modification by selling investment tax credits. These funds have been held in escrow and are used to fund operating deficits. Although occupancy in the Phoenix sub-market is generally in the low 90% range, the property is currently 80% occupied because of a fire. Repairs to the property are underway and will be covered by the borrower's property insurance. The Partnership has the option to call its remaining PIM by accelerating the maturity date of the loan. If the call feature is exercised for the whole PIM then the insurance feature of the loan would be canceled. Therefore, the Partnership will determine the merits of exercising the call option 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. CRITICAL ACCOUNTING POLICY The Partnership's critical accounting policy relates primarily to revenue recognition related to the participation feature of the Partnership's PIM investments. The Partnership's policy is as follows: Basic interest on PIMs is recognized at the stated rate of the Federal Housing Administration insured mortgage (less the servicer's fee) or the stated coupon rate of the Fannie Mae MBS. The Partnership recognizes interest related to the participation features when the amount becomes fixed and the transaction that gives rise to such amount is finalized, cash is received, and all contingencies are resolved. This could be the sale or refinancing of the underlying real estate, which results in a cash payment to the Partnership or a cash payment made to the Partnership from surplus cash relative to the participation feature. ITEM 7A QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK ASSESSMENT OF CREDIT RISK The Partnership's investments in its insured mortgage portion and MBS portion of its PIMs and its MBS are guaranteed and/or insured by GNMA, Fannie Mae, 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. These obligations are not guaranteed 5 <Page> by the U.S. Government or the Federal Home Loan Bank Board. However, Fannie Mae and FHLMC are two of the largest corporations in the United States with significant experience in mortgage securitizations. In addition, their MBS instruments carry the highest credit rating given to financial instruments. GNMA guarantees the full and timely payment of principal and basic interest on the securities it issues, which represents interest 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 $1.1 million of commercial paper, which is issued by entities with a credit rating equal to one of the top two rating categories of a nationally recognized statistical rating organization. INTEREST RATE RISK The Partnership's primary market risk exposure is to interest rate risk, which can be defined as the exposure of the Partnership's net income, comprehensive income or financial condition to adverse movements in interest rates. At December 31, 2001, the Partnership's PIMs and MBS comprise the majority of the Partnership's assets. Decreases in interest rates may accelerate the prepayment of the Partnership's investments. The Partnership does not utilize any derivatives or other instruments to manage this risk as the Partnership plans to hold its PIM investments to expected maturity, while it is expected that substantially all of the MBS will prepay over the same time period, thereby mitigating any potential interest rate risk to the disposition value of any remaining MBS. The Partnership monitors prepayments and considers prepayment trends, as well as distribution requirements of the Partnership, when setting regular distribution policy. For MBS, the fund forecasts prepayments based on trends in similar securities as reported by statistical reporting entities such as Bloomberg. For PIMs, the Partnership incorporates prepayment assumptions into planning as individual properties notify the Partnership of the intent to prepay or as they are scheduled to mature. The table below provides information about the Partnership's financial instruments that are sensitive to changes in interest rates. For mortgage investments, the table presents principal cash flows and related weighted average interest rates ("WAIR") by expected maturity dates. The expected maturity date is contractual maturity adjusted for expectations of prepayments. <Table> <Caption> Expected maturity dates ($ in thousands) ----------------------------------------------------------- 2002 2003 2004 2005 2006 Thereafter Total Fair Face Value(1) Value -------------------------------------------------------------------------------------- Interest-sensitive assets: MBS $ 256 $ 231 $ 211 $ 194 $ 181 $ 7,844 $ 8,917 $ 9,411 WAIR 8.41% 8.41% 8.41% 8.41% 8.41% 8.41% 8.41% PIMs 5,667 111 120 129 139 12,613 18,779 19,649 WAIR 7.38% 7.38% 7.38% 7.38% 7.38% 7.38% 7.67% -------- -------- ------- ------- -------- ---------- --------- --------- Total Interest- sensitive assets $ 5,923 $ 342 $ 331 $ 323 $ 320 $ 20,457 $ 27,696 $ 29,060 ======== ======== ======= ======= ======== ========== ========= ========= </Table> (1) The methodology used by the Partnership to estimate the fair value of each class of financial instrument is described in Note H to the Partnership's financial statements presented in Appendix A to this report. As described in that note, the Partnership does not include an estimate of value for the participation interest associated with its PIM investments. 6 <Page> RESULTS OF OPERATIONS The following discussion relates to the operation of the Partnership during the years ended December 31, 2001, 2000 and 1999. <Table> <Caption> (Amounts in thousands) 2001 2000 1999 ------- -------- -------- Interest income on PIMs: Basic interest $ 1,446 $ 1,423 $ 2,085 Participation interest 306 214 - Interest income on MBS 1,171 1,702 1,900 Other interest income 100 249 231 Partnership expenses (390) (449) (505) Amortization of prepaid fees and expenses (92) (101) (101) ------- -------- -------- Net income $ 2,541 $ 3,038 $ 3,610 ======= ======== ======== </Table> Net income decreased for 2001 when compared with 2000 primarily due to decreases in interest income on MBS and other interest income. This is partially offset by an increase in participation interest and a decrease in asset management fees. Interest income on MBS decreased in 2001 when compared to 2000 primarily due to the payoffs of the Boulders Apartments MBS in July 2001 and the Chateau Bijou MBS in September of 2000. Other interest income decreased due to lower average interest rates earned on cash balances available for short-term investing in 2001 as compared with 2000. Participation interest increased due to the collection of a prepayment premium from the Boulders Apartments MBS payoff in July 2001. The decrease in asset management fees is due to the Partnership's asset base declining. Net income decreased for 2000 when compared with 1999 due primarily to the decrease in interest income on PIMs and MBS. Basic interest on PIMs decreased in 2000 as compared to 1999 due primarily to the prepayment of the LaCosta PIM in December 1999. MBS interest income decreased in 2000 as compared to 1999 primarily due to principal collections received on the remaining MBS investments and the Chateau Bijou MBS payoff in September 2000. Participation interest increased in 2000 compared with 1999 due to the Chateau Bijou MBS prepayment premium and Shared Appreciation Interest from the LaCosta PIM payoff received in 2000. Expenses decreased in 2000 as compared with 1999 due primarily to lower asset management fees caused by a declining asset base. ITEM 8.

F- 7 <Page> KRUPP INSURED PLUS LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS ---------- A. ORGANIZATION Krupp Insured Plus Limited Partnership (the "Partnership") is a Massachusetts Limited Partnership. The Partnership was organized for the purpose of investing in multi-family loans and mortgage-backed securities. The General Partners of the Partnership are The Krupp Corporation and The Krupp Company Limited Partnership-IV and the Corporate Limited Partner is Krupp Depositary Corporation. The Partnership terminates on December 31, 2025, 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 7, 1986 and completed its public offering having sold 7,499,999 Units for $149,489,830 net of purchase volume discounts of $510,150 as of January 27, 1987. In addition, Krupp Depositary Corporation owns 100 Units. B. SIGNIFICANT ACCOUNTING POLICIES The Partnership uses the following accounting policies for financial reporting purposes which differ in certain respects from those used for federal income tax purposes (Note G): BASIS OF PRESENTATION The accompanying financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP"). MBS The Partnership, in accordance with Financial Accounting Standards Board's Statement 115, "Accounting for Certain Investments in Debt and Equity Securities" (FAS 115), classifies its MBS portfolio as available-for-sale. The Partnership classifies its MBS portfolio as available-for-sale as the Partnership expects that a portion of the portfolio at that time in order to close out the Partnership. In addition, other situations such as liquidity needs could arise which would necessitate the sale of a portion of the MBS portfolio. 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 investment in accordance with FAS 115, under the classification of held to maturity as this investment has a participation feature. As a result, the Partnership would not sell or otherwise dispose of the MBS. Accordingly, the Partnership has both the intention and ability to hold this investment to expected maturity. The Partnership carries this MBS at amortized cost. The Partnership holds insured mortgage portion of the Federal Housing Administration PIM (FHA PIM) at amortized cost and does not establish loan loss reserves as this investment is fully insured by the FHA. Basic interest on PIMs is recognized at the stated rate of the Federal Housing Administration insured mortgage (less the servicer's fee) or the stated coupon rate of the Fannie Mae MBS. The Partnership recognizes interest related to the participation features when the amount becomes fixed and the transaction that gives rise to such amount is finalized, cash is received and all contingencies are resolved. This could be the sale or refinancing of the underlying real estate, which results in a cash payment to the Partnership or a cash payment made to the Partnership from surplus cash relative to the participation feature. 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. Continued F- 8 <Page> KRUPP INSURED PLUS LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS, continued ---------- B. SIGNIFICANT ACCOUNTING POLICIES, continued PREPAID FEES AND EXPENSES Prepaid fees and expenses represent prepaid acquisition fees and expenses and prepaid participation servicing fees paid for the acquisition and servicing of PIMs. The Partnership amortizes the 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 estimated life of the underlying mortgage. The Partnership amortizes the prepaid participation servicing fees using a method that approximates the effective interest method over a ten year period beginning from the acquisition of the Fannie Mae MBS or final endorsement of the FHA loan. Upon the repayment of a PIM, any unamortized acquisition fees and expenses and unamortized participation servicing fees related to such loan are expensed. INCOME TAXES The Partnership is not liable for federal or state income taxes because Partnership income is allocated to the partners for income tax purposes. If the Partnership's tax returns are examined by the Internal Revenue Service or state taxing authority and such an 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 GAAP 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, 2001 and 2000, the Partnership had investments in two PIMs. The Partnership's PIMs consist of one Fannie Mae MBS representing the securitized first mortgage loan on the underlying property and one participation interest in a first mortgage loan originated under the FHA lending program on the underlying property (collectively the "insured mortgages"). The Partnership also has participation interests in the revenue stream and appreciation of the underlying properties above specified thresholds. The borrower conveys these participation features to the Partnership generally through a subordinated promissory note and mortgage (the "Agreement"). The Partnership receives monthly payments of principal and basic interest that are guaranteed by Fannie Mae on the MBS and insured by HUD on the FHA mortgage loan. The Partnership may receive income 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 30% of the monthly gross rental income generated by the underlying property in excess of a specified base, limited to the extent that it exceeds the amount of Minimum Additional Interest earned during such month or 25% of distributable surplus cash and (iii) "Shared Appreciation Interest" which is 30% of any increase in the value of the underlying property in excess of a specified base or 25% of the net sales proceeds. Payment of participation interest from the operations of the property is limited 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 over certain thresholds. Continued F- 9 <Page> KRUPP INSURED PLUS LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS, continued ---------- C. PIMs, continued 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 borrower may prepay the first mortgage loan subject to a 9% prepayment premium in years six through nine, a 1% prepayment premium in year ten and no prepayment premium thereafter. Under the Agreement, upon giving twelve months written notice, the Partnership 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. In December 1999, the Partnership received a prepayment in the amount of $9,746,923 representing the outstanding principal balance due on the La Costa PIM. The Borrower defaulted on the first mortgage loan underlying the PIM in June of 1999. The Partnership continued to receive its full principal and interest payments until the GNMA mortgagee exercised its right to prepay the GNMA MBS due to the continuing default of the underlying first mortgage loan. Subsequent to the payoff, the Partnership received $10,000 from the Borrower to release the Subordinated Promissory Note. This payment has been classified as Shared Appreciation Interest. On January 11, 2000, the Partnership paid a special distribution to the investors of $1.30 per Limited Partner interest. At December 31, 2001 and 2000 there were no loans within the Partnership's portfolio that were delinquent as to principal or interest. The Partnership's PIMs consist of the following at December 31, 2001 and 2000: <Table> <Caption> Approximate Original Interest Maturity Monthly Investment Basis at PIMs Face Amount Rates (a) Dates Payment December 31, - ---- ------------ --------- -------- ----------- --------------------------------- 2001 2000 ------------ ------------ FHA Vista Montana Apts.

FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS The Partnership used 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 because of the short maturity of those instruments. MBS The Partnership estimated the fair value of MBS based on quoted market prices while it estimated the fair value of insured mortgages based on quoted prices of MBS with similar interest rates. Based on the estimated fair value determined using these methods and assumptions, the Partnership's investments in MBS had gross unrealized gains of approximately $499,000 at December 31, 2001 and gross unrealized gains and losses of approximately $689,000 and $1,000 at December 31, 2000. Continued F- 14 <Page> KRUPP INSURED PLUS LIMITED PARTNERSHIP NOTES TO FINANCIAL STATEMENTS, continued ---------- H. FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS, continued PIMs As there is no active trading market for these investments, management estimates the fair value of the PIMs using quoted market prices of MBS having a similar interest rate. Management does not include any estimate of participation interest in the Partnership's estimated fair value for the Vista Montana PIM, as 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 of approximately $870,000 at December 31, 2001, and gross unrealized gains and losses of approximately $42,000 and $300,000 at December 31, 2000.
