                  KRUPP INSURED PLUS-III LIMITED PARTNERSHIP

                      AGREEMENT OF LIMITED PARTNERSHIP

     AGREEMENT dated as of the 22nd day of June, 1988, by and among Krupp Plus
Corporation, a Massachusetts corporation, and Mortgage Services Partners Limited
Partnership, a Massachusetts limited partnership, as General Partners; Krupp
Depositary Corporation, as the Corporate Limited Partner; and those Persons who
may hereafter be admitted to the Partnership as Investor Limited Partners. The
Corporate Limited Partner and the Investor Limited Partners are collectively
referred to herein as the "Limited Partners" and, together with the General
Partners, as the "Partners." Certain other terms used throughout this Agreement
are defined in Section 17 hereof.

     WHEREAS, the General Partners and the Corporate Limited Partner formed a
limited partnership (the "Partnership") by filing a Certificate of Limited
Partnership with the Secretary of State of The Commonwealth of Massachusetts on
March 21, 1988 and wish to continue the Partnership under this Agreement of
Limited Partnership and the provisions of the Massachusetts Uniform Limited
Partnership Act; and

     WHEREAS, the General Partners and the Corporate Limited Partner wish to
provide, among other matters, for (i) economic and other rights of investors
(the "Unitholders") in the Partnership who will purchase Units evidencing such
rights and who may, under certain circumstances, be admitted to the Partnership
as Investor Limited Partners; (ii) the assignment to the extent permitted by
Massachusetts law by the Corporate Limited Partner to the Unitholders of all of
its interest in distributions, including liquidating distributions, and profits
and losses of the Partnership and all of its other rights, duties and
obligations in connection with the Limited Partner Interests which correspond to
the Units; (iii) the obligation of the Corporate Limited Partner to exercise any
and all rights, duties and obligations with respect to such Limited Partner
Interests solely in favor of, in the interest of, and at the direction of the
Unitholders; (iv) the continued status of the Corporate Limited Partner as a
Limited Partner of the Partnership; and (v) the possible admission of Investor
Limited Partners subject to the terms and conditions herein specified;

     NOW THEREFORE, the parties hereto agree as follows:

     Section 1. CONTINUATION. The parties agree to continue the Partnership
pursuant to this Agreement and the provisions of the Uniform Limited Partnership
Act of The Commonwealth of Massachusetts (the "Act").

     Section 2. NAME AND OFFICE. The Partnership shall be conducted under the
name and style of "Krupp Insured Plus-III Limited Partnership." The principal
office and place of business of the Partnership shall be located at 470 Atlantic
Avenue, Boston, Massachusetts 02210, or at such other place as the General
Partners may from time to time determine and specify by written notice to all of
the Partners. The Partnership shall

                                       A-1
<Page>

at all times maintain in Massachusetts (i) an office at which shall be kept the
basic Partnership documents described in Section 12.2 hereof, and (ii) an agent
for service of process selected by the General Partners in accordance with any
relevant provisions of the Act as then in effect.

     Section 3. PURPOSES AND POWERS

     3.1 PURPOSES. The purpo50ses of the Partnership are to acquire, invest in,
maintain, hold, encumber, sell, exchange, manage and otherwise deal with the
Mortgages of the Partnership.

     3.2 POWERS. In furtherance of the above purposes, the Partnership shall
have the powers:

     (a) to acquire, hold, sell, encumber, exchange and otherwise dispose of
guaranteed or federally insured mortgages on multi-family residential properties
("Insured/Guaranteed Mortgages") through the purchase of mortgage-backed
securities guaranteed as to principal and basic interest issued or originated
under or in connection with the housing programs of HUD, GNMA, FNMA, or FHLMC
("MBS"), some of which Insured/Guaranteed Mortgages may provide for Partnership
participation in the operating revenues and residual value of the underlying
properties ("Participating Insured Mortgages") on both a current settlement and
a forward delivery (i.e. beyond a 5-day corporate settlement period) basis;

     (b) to acquire, invest in, maintain, hold, encumber, sell, exchange, manage
and otherwise dispose of MBS backed by mortgages on single-family residential
properties not providing a participation feature ("Single-Family MBS") on both a
current settlement and a forward delivery (i.e. beyond a 5-day corporate
settlement period) basis;

     (c) to acquire, invest in, maintain, hold, encumber, sell, exchange, manage
and otherwise dispose of MBS backed by mortgages on multi-family residential
properties not providing a participation feature ("Multi-Family MBS") on both a
current settlement and a forward delivery (i.e. beyond a 5-day corporate
settlement period) basis; and

     (d) to acquire, invest in, maintain, hold, encumber, sell, exchange, manage
and otherwise dispose of conventional participating and non-participating
mortgage loans which are insured or guaranteed ("Other Mortgages");

     (e) subject to any applicable statutes and regulations, to borrow money to
further the purposes of the Partnership, to issue evidences of indebtedness in
respect thereof and to secure the same by mortgage or pledge or grant of lien on
or other security interest in a Mortgage or any other assets of the Partnership;
and

     (f) to do all things, carry on any activities and enter into, perform,
modify, supplement or terminate any contracts necessary to, in connection with
or incidental to the furtherance of the purposes of the Partnership, all so long
as such things, activities and contracts may be lawfully done, carried on or
entered into by the Partnership under

                                       A-2
<Page>

the laws of The Commonwealth of Massachusetts and the United States of America
and under the terms of this Agreement.

     The Partnership shall not engage in any business not provided for in this
Section 3.2 without the Consent of the holders of a majority of the Limited
Partner Interests.

     Section 4. TERM. The term of the Partnership shall end at midnight on
December 31, 2028, unless the Partnership is sooner dissolved or terminated as
provided in Section 11 hereof.

     Section 5. CAPITAL CONTRIBUTIONS.

     5.1 CONTRIBUTIONS OF GENERAL PARTNERS. The General Partners have
contributed in cash in respect of their Interests an aggregate of $3,000, in the
respective amounts set forth opposite their name in Schedule A hereto. Upon the
dissolution and termination of the Partnership, the General Partners will
contribute to the Partnership an amount equal to the lesser of (i) the deficit
balances in their Capital Accounts or (ii) the excess of one and one-hundredths
percent (1.01%) of the total Capital Contributions of the Limited Partners over
the amount of capital previously contributed by the General Partners.

     5.2 CONTRIBUTIONS OF LIMITED PARTNERS. The Corporate Limited Partner has
contributed $2,000 in cash in respect of 100 Limited Partner Interests. Upon the
purchase of Units by Unitholders, the Corporate Limited Partner shall contribute
in cash to the Partnership the Subscription Prices paid by the Unitholders,
shall receive Limited Partner Interests in return therefor, shall assign all its
rights with respect to such Interests to the Unitholders to the extent permitted
by Massachusetts law, shall agree to exercise any and all rights with respect to
such Interests as directed by the Unitholders, and shall remain a Limited
Partner with respect to such Interests as permitted by the Act. Not fewer than
250,000 Units (not including Units purchased by the General Partners and their
Affiliates) and not more than 20,000,000 Units will be sold. An investor who
tenders payment for a Unit and accepts confirmation of purchase without
objection for a ten-day period following the mailing of such confirmation shall
thereby have assented to all of the terms and conditions of this Agreement.

     5.3 SALE OF ADDITIONAL LIMITED PARTNER INTERESTS OR UNITS. Subsequent to
the final closing of the sale of not fewer than 250,000 Units (not including
Units purchased by the General Partners and their Affiliates) and not more than
20,000,000 Units, the Partnership may not sell additional Limited Partner
Interests or Units; provided, however, that this Section shall not prevent a
Unitholder from exchanging Units for Limited Partner Interests pursuant to
Section 7.6(h) hereof.

     5.4 CAPITAL ACCOUNTS. A Capital Account shall be established and maintained
for each General Partner, Limited Partner, and Unitholder. The Capital Account
of each Partner shall be (a) credited with all payments made to the Partnership
by such Partner on account of Capital Contributions and with allocations to such
Partner of Partnership Profits for Tax Purposes and tax-exempt income, and (b)
charged with allocations to such

                                       A-3
<Page>

Partner of Partnership Losses for Tax Purposes, with other Partnership
expenditures which are not deductible for federal income tax purposes (not
including payments of indebtedness or expenditures included in the basis of any
Partnership asset), and with cash distributions made to such Partner as
distributions of Cash Flow or of Net Cash Proceeds of Capital Transactions and
the Terminating Capital Transaction, and shall otherwise appropriately reflect
transactions of the Partnership and the Partners, all as provided in Treasury
Department Regulations section 1.704-1(b). The Capital Account of each
Unitholder shall be kept in the same manner as the Capital Account of a Partner,
and to the extent Capital Contributions of, and allocations and distributions
to, the Corporate Limited Partner are attributable to Unitholders who are not
Limited Partners, such items shall be reflected in the Capital Accounts of such
Unitholders and not the Capital Account of the Corporate Limited Partner. A
Substitute General or Limited Partner shall be deemed to have made the Capital
Contribution to the Partnership which was made with respect to the Interest
transferred or exchanged and to have received from the Partnership the credits,
allocations and charges with respect to such Interest and shall otherwise
succeed to the Capital Account kept with respect to such Interest.

     5.5 ADDITIONAL CAPITAL CONTRIBUTIONS; INTERPRETATION. No Partner or
Unitholder shall be required to make any Capital Contribution, or be entitled to
bring an action for partition against the Partnership, or to demand or receive
any distribution of or with respect to his Capital Contribution except as is
specifically provided under this Agreement. No loan made by a General Partner,
Limited Partner or Unitholder to the Partnership shall constitute a Capital
Contribution for any purpose.

     Section 6. GENERAL PARTNERS.

     6.1 EXTENT OF POWERS AND DUTIES.

     (a) GENERAL. Except as expressly limited by the provisions of this
Agreement, the General Partners shall have complete and exclusive discretion in
the management and control of the affairs and business of the Partnership and
all powers necessary, convenient or appropriate to carry out the purposes,
conduct the business and exercise the powers of the Partnership. Except as so
expressly limited, the General Partners shall possess and enjoy with respect to
the Partnership all of the rights and powers of partners of a partnership
without limited partners to the extent permitted by Massachusetts law.

     (b) POWERS AND DUTIES. The General Partners shall diligently and faithfully
exercise their discretion to the best of their ability and use their best
efforts during so much of their time as may be necessary to carry out the
purposes and conduct the business of the Partnership in accordance with this
Agreement and in the best interests of the Partnership and so as, consistent
therewith, to protect the interests of the Investor Limited Partners and
Unitholders as a group. The General Partners shall have fiduciary responsibility
for the safekeeping and use of all funds and assets of the Partnership, whether
or not in its immediate possession or control, and they shall not employ or
permit another Person to employ such funds or assets in any manner except for
the exclusive benefit of the Partnership. In particular, the General Partners,
solely, shall be responsible for and shall use their best efforts and exercise
discretion to the best of their ability: (i) to

                                       A-4
<Page>

cause Mortgages to be acquired, held, and sold, exchanged or otherwise disposed
of; (ii) assure the proper application of revenues of the Partnership; (iii) to
maintain proper books of account for the Partnership and to prepare all reports
of operations and tax returns which are to be furnished to the Partners and
Unitholders pursuant to this Agreement or which are required by taxing bodies or
other governmental agencies; (iv) to maintain adequate insurance with respect to
any insurable property of the Partnership pursuant to policies of insurance in
form and coverage customary for such property; and (v) to assure the doing of
all other things which may be necessary or advisable in connection with the
supervision of the affairs, business and property of the Partnership.

     (c) AMPLIFICATION OF POWERS AND DUTIES. As amplification, and not by way of
limitation on the powers expressed herein, the General Partners shall have,
subject to the provisions of this Agreement, full power and authority on behalf
of the Partnership, in order to carry out and accomplish its purposes and
functions: (i) to expend Partnership capital and income; (ii) to purchase, sell,
convey, exchange, divide, combine and otherwise transact business with respect
to interests in Mortgages, and in that connection to employ engineers,
contractors, attorneys, accountants, brokers, appraisers, and such other
consultants, advisors, artisans, and workmen as may be necessary or advisable
for the purpose; (iii) to designate depositories of the Partnership's funds, and
the terms and conditions of such deposits and drawings thereon; (iv) to borrow
money or otherwise to procure extensions of credit for the Partnership, as
security therefor to pledge, hypothecate, mortgage, assign, transfer, and grant
security interests in the Mortgages, to enter into reverse repurchase (resale)
agreement transactions involving such Mortgages, and in connection therewith to
execute, seal, acknowledge and deliver promissory notes, guarantees, security
and other agreements, assignments and any other written documents; (v) to
execute and deliver documents and instruments relating to real and personal
property of whatever kind and description, including, but not limited to, deeds,
mortgages, leases and other documents of title or conveyance, regulatory
agreements with governmental bodies and agencies, powers of attorney, and other
contracts, instruments and agreements of all kinds; (vi) to hold all or any
portion of the Mortgages in the name of one or more trustees, nominees or other
agents of or for the Partnership for the purpose of facilitating transactions
involving said Mortgages; (vii) to establish reserves, in their discretion, for
any proper Partnership purpose; (viii) to invest the proceeds of the offering of
Units on an interim basis as provided in Section 6.2(a) hereof for a period of
up to 24 months after the date of the Partnership's Prospectus; (ix) to reinvest
the proceeds of the sale or other realization of a Mortgage if such Mortgage is
repaid or sold by the Partnership within five years after the final closing of
the sale of Units; (x) to offer and sell the Units to the public directly or
through any licensed Affiliate of the General Partners and to employ personnel,
agents and dealers for such purpose; (xi) to receive interest from the escrow
agent with respect to the Subscription Prices and to cause the first
distribution to a Unitholder to include the amount, if any, attributable to such
interest on account of subscription payments accepted prior to the initial
closing of the sale of Units; (xii) to appoint a transfer agent with respect to
the Units; (xiii) to list the Units on the American Stock Exchange or another
national securities exchange or to withdraw the Units from such listing and take
such actions as they deem appropriate therefor; (xiv) to take such steps as the
General Partners determine are advisable or necessary and will not result in any
material adverse effect on the

                                       A-5
<Page>

economic position of a majority in interest of the Investor Limited Partners and
the Unitholders with respect to the Partnership in order to preserve the tax
status of the Partnership as a pass-through entity for federal income tax
purposes, including, without limitation, removing the Units from public trading
markets, if they have been listed, causing the Corporate Limited Partner to
impose restrictions on transfers of Units or Limited Partner Interests (provided
such restrictions on transfers do not cause the Partnership's Assets to be
deemed to be "plan assets" with respect to investors which are Qualified Plans);
(xv) to take such steps as the General Partners determine are advisable or
necessary and will not result in any material adverse effect on the economic
position of a majority in interest of the Investor Limited Partners and the
Unitholders with respect to the Partnership to restructure the Partnership and
its activities to obtain a prohibited transaction exemption from the Department
of Labor or to comply with any exemption in final plan asset regulations adopted
by the Department of Labor, including, but not limited to, establishing a fixed
percentage of Units permitted to be held by Qualified Plans or other tax-exempt
investors or discontinuing sales to such entities after a given date, in the
event that either the assets of the Partnership constitute "plan assets" for
purposes of ERISA or the transactions contemplated hereunder constitute
prohibited transactions under ERISA or the Code and an exemption for such
transactions is not obtainable from the Department of Labor; (xvi) to take such
steps as the General Partners determine are advisable or necessary without the
prior Consent of the holders of a majority of the Limited Partner Interests, to
restructure the Partnership and its activities, including amending this
Agreement, in order to enable the Partnership to qualify as a real estate
investment trust or, if possible, as a real estate mortgage investment conduit
for federal income tax purposes; provided, however, that if the Partnership is
so restructured, ratification of such restructuring will be required by the
holders of a majority of the Limited Partner Interests; and (xvii) in general to
do all things and execute all documents the General Partners shall deem
necessary or convenient to accomplish the purposes of the Partnership, or to
protect and preserve the Mortgages, to the same extent as if they owned such
Mortgages individually. All the powers of the General Partners enumerated above,
may be carried out by the General Partners and the Corporate Limited Partner
acting on behalf of the Unitholders without any canvassing of or voting by the
Unitholders.

     (d) ACCEPTANCE OF UNITHOLDERS. The General Partners' right to accept as
Unitholders prospective transferees of Units is set forth in Section 7.2 hereof.
The General Partners shall have the right to accept as initial Unitholders such
Persons (including the General Partners and their Affiliates) as may acquire at
least 250 Units or, in the case of IRAs, Keogh and Qualified Plans, 100 Units,
up to an aggregate of not fewer than 250,000 Units (not including Units
purchased by the General Partners and their Affiliates) and not more than
20,000,000 Units. Persons desiring to become initial Unitholders shall comply
with the subscription procedures established by the General Partners. Every
subscription shall be subject to acceptance by the General Partners. If
subscriptions are received and accepted respecting not fewer than 250,000 Units
(excluding Units subscribed for by the General Partners and their Affiliates),
the initial closing of the sale of Units shall occur. The General Partners will
accept or reject each subscription for Units within 30 days after they receive
it; if rejected, all subscription payments which accompanied such rejected
subscription shall be returned to the

                                       A-6
<Page>

subscriber within 10 business days. If the Subscriber Signature Page submitted
by or on behalf of a prospective investor is incomplete or otherwise defective,
and the deficiency is not corrected, the General Partners will reject the
subscription approximately 15 days after it was received by the Partnership. If
a subscription is rejected by the General Partners due to such a deficiency or
for any other reason, the subscription payment (or appropriate portion thereof
in the case of a partial acceptance) will be promptly returned to the
prospective investor without interest or deduction. No General Partner or
Affiliate of a General Partner or any underwriter, dealer or salesman of Units
shall directly or indirectly pay or award any finder's fee, commission or other
compensation to any Person engaged by a potential Unitholder for investment
advice as an inducement to such advisor to advise the purchase of Units;
provided, however, that this provision shall not prohibit the normal sales
commission and sales incentive payable to a registered broker-dealer or other
properly licensed Person for selling Units. Within 15 days after a successful
completion of the minimum offering, the Subscription Prices for such Units shall
be contributed in cash to the Partnership, the Corporate Limited Partner shall
receive the Limited Partner Interests corresponding to such Units, the
assignment to the Unitholders and their contractual rights under Section 7.6(b)
hereof with respect to such Units shall commence, and the General Partners shall
prepare and file an amendment to the Certificate of Limited Partnership which
shall reflect the contribution to the Partnership of the Subscription Price of
such Units. Thereafter, Subscription Prices will be contributed to the
Partnership as described above until the termination of the offering of the
Units. The General Partners shall prepare and file from time to time during the
offering of Units, and at least once every 30 days, further amendments to the
Certificate of Limited Partnership to reflect the increase of the Capital
Contribution of the Corporate Limited Partner on behalf of the Unitholders.
Until acceptance of their subscriptions by the General Partners, subscribers
will not be Unitholders, but their subscription payments will be held in trust
on their behalf and will be returned to the subscribers in the event they are
not accepted as Unitholders.

     (e) MAINTENANCE OF NET WORTH. The General Partners shall at all times use
their best efforts to maintain their combined net worth at a sufficient level to
meet all requirements of the Code under currently applicable regulations of the
Treasury Department to permit the Partnership to be classified for federal
income tax purposes as a partnership and not as an association taxable as a
corporation, and shall, irrespective of such requirements, maintain such net
worth on a fair market basis at an amount at least equal to $1,000,000.

     (f) DELEGATION OF POWERS. Each General Partner, while there is more than
one, may act on behalf of the Partnership in connection with any particular
matter affecting the Partnership, including the authority to execute notes,
deeds, mortgages and other instruments. Except as otherwise provided under this
Agreement or by law, the General Partners may delegate all or any of their
duties under this Agreement to any of their own respective partners, officers or
employees, and in furtherance of such delegation may elect, employ, contract or
deal with any Person (including any General Partner or any Affiliate of a
General Partner).

                                       A-7

     (g) RELIANCE BY THIRD PARTIES. No Person dealing with the Partnership, or
its Mortgages, whether as mortgagee, assignee, purchaser, lessee, grantee or
otherwise, shall be required to investigate the authority of the General
Partners, or any General Partner purporting to act in behalf of the other
General Partners, in selling, assigning, leasing, mortgaging, conveying or
otherwise dealing with any Partnership Mortgages or any part thereof, nor shall
any such assignee, lessee, purchaser, mortgagee, grantee or other Person
entering into a contract with the Partnership be required to inquire as to
whether the approval of the Partners or Unitholders for any such sale,
assignment, lease, mortgage, transfer or other transaction has been first
obtained. Any such Person shall be conclusively protected in relying upon a
certificate of authority or any other material fact signed by any General
Partner, or in accepting any instrument signed by any General Partner in the
name and behalf of the Partnership or the General Partners.

     6.2 LIMITATIONS ON THE EXERCISE OF POWERS OF GENERAL PARTNERS. The General
Partners shall have no power to take any action prohibited by this Agreement or
by the Act. Furthermore, in their administration of the Partnership's affairs,
the General Partners shall be subject to the following specific limitations:

     (a) INVESTMENT OBJECTIVES AND POLICIES. The Partnership's Investment in
Mortgages shall not be less than eighty-seven percent (87%) of the gross
proceeds of the Partnership's offering of Units, and Front-End Fees and Expenses
payable from such gross proceeds shall not exceed thirteen percent (13%) of such
gross proceeds. The Partnership shall invest primarily in Participating Insured
Mortgages, but may also invest in Single-Family and Multi-Family MBS, and
insured, multi-family mortgage loans. To the extent that the General Partners
determine that suitable Participating Insured Mortgages are not available for
investment of the proceeds of the offering of Units, the General Partners may,
in their sole discretion, invest such portion of said proceeds as they deem
appropriate in Other Mortgages. The General Partners shall attempt to structure
any borrowings to avoid producing unrelated business taxable income which would
obligate a tax-exempt entity holding Units to file a federal income tax return
or to pay federal income tax as a result. On an interim basis, the Partnership
may invest its funds either in (i) United States Government securities, other
United States Government guaranteed money instruments, certificates of deposit
of Qualified Banks, bank repurchase agreements with respect to securities of the
United States Government or governmental agencies, commercial paper issued by
entities with a credit rating equal to one of the top two rating categories of a
nationally recognized statistical rating organization, repurchase agreements
with respect to MBS guaranteed by GNMA, FNMA or FHLMC issued by financial
institutions or corporations having total assets in excess of $500 million,
bankers' acceptances, floating rate MBS, short term debt obligations of FNMA and
FHLMC, and similar money market investments, or (ii) shares of public investment
companies registered with the Securities and Exchange Commission whose assets
exceed $50,000,000 and are invested in the foregoing types of investments and
held by an independent custodian. The General Partners shall attempt to manage
the Partnership's investments in Mortgages and its interim investments to make
sure that the Partnership shall not be deemed an investment company as such term
is defined in the Investment Company Act of 1940. The Partnership shall not
redeem or repurchase

                                       A-8
<Page>

Limited Partnership Interests or Units and shall not underwrite the securities
of other issuers.

     (b) SALES OF MORTGAGES FROM OR TO THE GENERAL PARTNERS AND THEIR
AFFILIATES. The Partnership shall not purchase or acquire any Mortgage from any
General Partner or any Affiliate of any General Partner or any Person in which
any General Partner or Affiliate has a material interest including, without
limitation, any partnership of which any General Partner or Affiliate of a
General Partner is a partner. Notwithstanding the foregoing, the General
Partners or their Affiliates may (1) originate mortgages for purchase by the
Partnership or (2) purchase a Mortgage in their own name, and assume loans in
connection therewith and temporarily hold title thereto for the purpose of
facilitating the acquisition of such Mortgage or the borrowing of money for the
Partnership, or any other purpose related to the business of the Partnership,
provided that (i) such Mortgage is purchased by the Partnership for a Purchase
Price (and related cash investment) no greater than the Purchase Price (and
related cash investment) in such Mortgage (including, without limitation, equity
payments, transfer taxes, financing and closing costs) made or agreed to be made
by the General Partners or their Affiliates, except for payment of Acquisition
Expenses to the extent permitted by this Agreement, (ii) there is no difference
in interest rates of the loans secured by the Mortgage at the time acquired by
the General Partners or their Affiliates and the time acquired by the
Partnership, and (iii) no other payment directly or indirectly arising out of
such transaction is received by, nor any other benefit conferred upon, any
General Partner or Affiliate thereof apart from compensation payable by a
Borrower to Krupp Mortgage Corporation for services rendered in connection with
the origination, servicing or coinsurance of Mortgages which are purchased by
the Partnership, subject to the limits on compensation mandated by HUD, GNMA,
FNMA or FHLMC or compensation otherwise permitted by this Agreement. The
Partnership shall not sell any Mortgage to any General Partner or any Affiliate
of a General Partner.

     (c) NO TRANSACTIONS WITH AFFILIATED BORROWERS. The Partnership shall not
invest in any Mortgages for which the Borrower is an Affiliate of the General
Partners.

     (d) LOANS TO OR FROM THE GENERAL PARTNERS AND THEIR AFFILIATES. No loans
may be made by the Partnership to any General Partner or any Affiliate of a
General Partner. A General Partner or any Affiliate of a General Partner may
loan funds to the Partnership but only with interest rates and other finance
charges and fees not in excess of the amounts that are charged by unrelated
banks on comparable loans for the same purpose in the locality of the property
underlying or subject to the Mortgage in connection with which the loan was
made, and in no event shall the annual interest rate charged on any such loan
exceed by more than 2% the base rate of Bank of New England, N.A., Boston,
Massachusetts. In addition, (i) to the extent that the General Partners or their
Affiliates shall themselves borrow the funds which they loan to the Partnership,
the interest rates and other finance charges charged to the Partnership shall
not exceed the corresponding amounts paid by the General Partners or their
Affiliates, and (ii) neither any General Partner nor any Affiliate of a General
Partner shall make loans to the Partnership with a prepayment charge or penalty
which is evidenced or secured by either a first or junior or all-inclusive note
or mortgage except to the extent that such prepayment charge or

                                       A-9
<Page>

penalty is attributable to an underlying encumbrance. In the event the
Partnership utilizes any all-inclusive (or "wrap-around") note issued by the
Partnership to the General Partners or an Affiliate thereof, said note shall
provide that the Partnership shall receive credit on its obligations under said
note for payments made by the Partnership directly on the underlying encumbrance
and that a bank, escrow company or other paying agent shall collect payments
(other than any initial payment of prepaid interest or loan points not to be
applied to the underlying encumbrance) on the all-inclusive note and make
disbursements therefrom to the holder of the underlying encumbrance prior to
making any disbursement to the holder of the all-inclusive note or, in the
alternative, all payments on the all-inclusive note and underlying notes shall
be made directly by the Partnership. In addition, no General Partner or
Affiliate of a General Partner shall receive interest on the amount of the
underlying encumbrance included in any all-inclusive note in excess of that
payable to the lender on that underlying encumbrance.

     (e) EXCHANGE OF INTERESTS FOR MORTGAGES. The Partnership shall not acquire
any Mortgage in exchange for Interests in the Partnership.

     (f) JOINT VENTURE INVESTMENTS. The Partnership shall not make investments
in the limited partner interests of any other program, or enter into any joint
venture which owns a particular Mortgage except with a partnership sponsored by
the General Partners or their Affiliates or with any other non-Affiliated Person
deemed suitable by the General Partners. The Partnership may enter into a joint
venture with a Joint Venture Partner only if the Partnership acquires a
controlling interest in any such venture, unless such joint venture is with
another partnership sponsored by the General Partners or their Affiliates as
described below. For purposes hereof, the Partnership shall be deemed to have a
"controlling interest" in such venture if the Partnership holds an interest of
not less than 50% in the capital and profits of the venture and the joint
venture agreement or related documents grants to the Partnership the joint right
to make or participate in basic management decisions concerning the sale,
leasing, refinancing or other realization of the Mortgage. The Partnership may
not enter into a joint venture with any other partnership sponsored by the
General Partners or their Affiliates unless (i) the Joint Venture Partner shares
similar investment objectives and management compensation provisions to those of
the Partnership; and (ii) the investments by the Partnership and such affiliated
partnership are on substantially the same terms and conditions. If the Joint
Venture Partner is an Affiliate of the Partnership, in the event of a proposed
sale of the Mortgage held by the joint venture initiated by either Joint Venture
Partner, the Partnership must have a right of first refusal to purchase the
other party's interest. The General Partners, in their capacity as managers of
the Partnership, shall not do, or cause a joint venture to do, any act which
would not be permitted hereunder if title to the Mortgage held by such joint
venture were held directly by the Partnership, and no joint venture shall be
entered into by the Partnership which involves the payment of duplicative
management or other fees or which would have the effect of circumventing any of
the restrictions on and prohibitions of transactions involving conflicts of
interest contained herein. The General Partners may permit one or more Joint
Venture Partners (other than Affiliates) to acquire or retain an equity interest
in any joint venture which owns a particular Mortgage for any consideration
deemed appropriate and fair by the General Partners under the circumstances
including the contribution of an equity interest in property, a right to

                                      A-10
<Page>

purchase property, cash or other property. The Partnership may permit any Person
deemed suitable by the General Partners, which may include without limitation a
partnership sponsored by the General Partners or their Affiliates, to acquire
MBS which represent interests in mortgage loans that also underlie Mortgages
held by the Partnership. Should another Person acquire an interest in an MBS
backed by a property with respect to which the Partnership holds a Participating
Insured Mortgage, the Partnership may grant such other Person an interest in the
current income stream and/or the residual value of such property.

     (g) LIMITATIONS ON INVESTMENTS IN OTHER MORTGAGES. To the extent the
Partnership invests in Other Mortgages, the following restrictions shall apply
with respect to such Other Mortgages only: (i) the Partnership will not invest
in Other Mortgages on any one underlying property which would exceed, in the
aggregate, an amount equal to 20% of the Capital Contributions of the Limited
Partners; (ii) the Partnership will not invest in Other Mortgages to or from any
one Borrower which would exceed, in the aggregate, an amount greater than 20% of
the Capital Contributions of the Limited Partners; (iii) the Partnership shall
not invest in real estate contracts of sale otherwise known as land sale
contracts, unless such contracts of sale are in recordable form and are
appropriately recorded in the chain of title; (iv) the Partnership shall not
invest in Other Mortgages on any unimproved real property in an amount in excess
of 25% of the Capital Contributions of the Limited Partners; (v) the Partnership
shall not invest in Other Mortgages on any one property if the aggregate amount
of all mortgage loans outstanding on the property, including the mortgage loans
of the Partnership, would exceed an amount equal to 85% of the appraised value
of the property as determined by an independent appraisal unless substantial
justification exists because of the presence of other underwriting criteria; and
(vi) the Partnership may borrow money to the extent necessary to prevent
defaults under existing loans, as when the Partnership has taken over the
operation of property and there is a need for additional capital. The
limitations contained in this Section 6.2(g) shall not apply to investments in
Participating Insured Mortgages or other MBS.

     6.3 LIABILITY FOR ACTS OR OMISSIONS AND INDEMNIFICATION. No General Partner
or Affiliate of a General Partner performing services on behalf of the
Partnership shall be liable, responsible or accountable in damages to any of the
Partners, Unitholders or the Partnership for any act or omission of any General
Partner in good faith on behalf of the Partnership and within the scope of the
authority granted to the General Partners by this Agreement and in the best
interests of the Partnership, except for acts or omissions constituting
negligence, misconduct or breach of fiduciary duty. The General Partners and
their respective Affiliates performing services within the scope of the General
Partners' duties shall be entitled to indemnity from the Partnership for any
loss, damage, or claim by reason of any act or omission performed or omitted by
the General Partners or such Affiliates in good faith on behalf of the
Partnership and within the scope of the authority granted to the General
Partners by this Agreement and in the best interests of the Partnership, except
that they shall not be entitled to be indemnified in respect of any loss, damage
or claim incurred by reason of negligence, misconduct, or breach of fiduciary
duty. Any indemnity under this Section shall be provided out of and to the
extent of Partnership assets only, and no Partner or Affiliate of any Partner
shall have or

                                      A-11
<Page>

incur any personal liability on account thereof. In no event shall the
Partnership assume the cost of any portion of liability insurance which would
insure the General Partners or any of their Affiliates for any liability as to
which the General Partners or their Affiliates are prohibited from being
indemnified by the Partnership.

     The Partnership shall not advance any funds to any General Partner or
Affiliate of a General Partner for legal expenses and other costs incurred as a
result of any legal action initiated against such General Partner or its
Affiliates by any Investor Limited Partner or Unitholder of the Partnership.
Notwithstanding the foregoing, the Partnership may provide such advances to the
General Partners or their Affiliates for legal expenses and other costs incurred
as a result of legal action if the following three conditions are satisfied: (i)
the legal action relates to the performance of duties or services by the General
Partners or their Affiliates on behalf of the Partnership, (ii) the legal action
is initiated by a third party who is not an Investor Limited Partner or
Unitholder of the Partnership, and (iii) the General Partners or their
Affiliates undertake to repay the advanced funds to the Partnership in cases in
which they would not be entitled to indemnification.

     Notwithstanding the foregoing, neither the General Partners nor any of
their respective Affiliates nor any broker-dealer shall be indemnified by the
Partnership for liabilities arising under federal and state securities laws
unless (i) there has been a successful adjudication on the merits of each count
involving alleged securities law violations as to the particular indemnitee, and
a court approves indemnification of litigation costs, or (ii) such claims have
been dismissed with prejudice on the merits by a court of competent jurisdiction
as to the particular indemnitee and a court approves indemnification of
litigation costs, or (iii) a court of competent jurisdiction approves a
settlement of the claims against a particular indemnitee and finds that
indemnification of the settlement and related costs should be made. In any claim
for indemnification for federal or state securities law violations, the party
seeking indemnification shall place before the court the position of the
Securities and Exchange Commission, the Massachusetts Securities Division, the
Tennessee Securities Division and the State Securities Commissioners with
respect to the issue of indemnification for securities law violations.

     6.4 COMPENSATION OF THE GENERAL PARTNERS AND THEIR AFFILIATES. The General
Partners and their Affiliates shall be entitled to receive from the Partnership
the following amounts in addition to distributions made to them pursuant to
Section 8 hereof:

     (a) The Partnership is authorized to enter into a Sales Agent Agreement
with Krupp Securities Corporation under which Krupp Securities Corporation shall
agree to act as managing underwriter for the offering of Units made pursuant to
Section 6.1(d) hereof. Krupp Securities Corporation will in turn enter into
Selected Dealer Agreements with participating selected dealers. Pursuant to the
Sales Agent Agreement and the Selected Dealer Agreements, Krupp Securities
Corporation or the participating selected dealers, as the case may be, shall be
entitled to receive out of the gross proceeds of such offering the following
compensation: (1) a sales commission of up to a maximum of $35 (3.5%) per $1,000
of Units sold and (2) an accountable

                                      A-12
<Page>

reimbursement of due diligence expenses incurred by prospective selected dealers
up to a maximum of $5 (1/2%) per $1,000 of Units sold. The Partnership in its
sole discretion may also pay up to a maximum of 0.5% of the gross proceeds of
the offering as a non-accountable allowance (the "Non-Accountable Allowance") to
the participating selected dealers for their underwriting, legal and marketing
expenses.

     (b) For services rendered in connection with the acquisition of Mortgages
by the Partnership, the Partnership shall pay to the General Partners or their
Affiliates at the initial closing and each closing thereafter of the sale of
Units an Acquisition Fee of 2.9% of the gross proceeds of the offering of Units.
Such Acquisition Fee will be reduced, however, to the extent of any amounts paid
to non-affiliated Originators by the Borrowers of the loans secured by such
Mortgages as part of the origination fee in recognition of the participation
feature of the Participating Insured Mortgages which non-affiliated Originators
may collect and pay over to the General Partners. In addition, the Partnership
shall reimburse the General Partners and their Affiliates for accountable
Acquisition Expenses incurred up to 0.5% of the gross proceeds of the offering
of Units and will pay the General Partners and their Affiliates a
non-accountable Acquisition Expense allowance of 1.5% of the gross proceeds of
the offering. In the event that any other fee or commission is incurred by the
Partnership in connection with the selection or purchase of any Mortgage by the
Partnership, whether designated as a commission, acquisition fee, finder's fee,
selection fee, consulting fee or any fee of similar nature however designated
and however treated for tax or accounting purposes, it shall be paid by the
General Partners and their Affiliates out of the Acquisition Fee.

     (c) For services to be rendered in connection with the servicing of the
participation features of the Participating Insured Mortgages throughout their
term and upon their sale or other realization, the Partnership shall prepay the
General Partners or their Affiliates at the initial closing and each closing
thereafter a Participation Servicing Fee equal to 1.6% of the gross proceeds of
the offering of Units.

     (d) For services rendered in managing the business of the Partnership, the
Partnership shall pay to the General Partners or their Affiliates, subject to
the provisions of Section 6.4(f) hereof, an Asset Management Fee equal to 0.75%
per annum of the value of the Total Invested Assets of the Partnership, payable
quarterly.

     (e) For services rendered in managing the business of the Partnership, the
Partnership shall pay to the General Partners or their Affiliates, subject to
the provisions of Section 6.4(f) hereof, an Incentive Management Fee in an
amount equal to 0.3% per annum of the Partnership's Total Invested Assets, but
payment of such Fee will be subordinated to the extent necessary for the
Unitholders and Investor Limited Partners to receive under Section 8.2 an amount
for such year equal to an 11% non-cumulative annual return on their Invested
Capital.

     (f) The total fees payable to the General Partners or their Affiliates
under Sections 6.4(d) and 6.4(e) hereof shall not exceed 10% of Distributable
Cash Flow. Such total fees may only exceed 10% of Distributable Cash Flow in any
fiscal year to the extent that such 10% cap was not met in prior fiscal years.

                                      A-13
<Page>

     (g) Subject to the provisions of Section 12.4 hereof, the Partnership shall
reimburse the General Partners and their Affiliates for certain expenses
incurred in connection with the organization and operation of the Partnership,
the offering of Units and the acquisition and disposition of Mortgages.
Front-End Fees and Expenses, including the Origination Fees, if any, will not
exceed 18% of the gross proceeds of the Partnership's offering.

     (h) Neither the General Partners nor their Affiliates shall be reimbursed
by the Partnership for services for which they are being compensated by way of
fees described in Subsections 6.4(d) and (e) above. However, the fees described
in such Subsections are not compensation for the costs of those certain
administrative functions for which the General Partners or their Affiliates are
entitled to reimbursement pursuant to Section 12.4 hereof, nor are any of the
fees described in this Section 6.4 compensation for the fees payable by
Borrowers to Krupp Mortgage Corporation for services rendered in connection with
the origination, servicing or coinsurance of Mortgages purchased by the
Partnership subject to the limits on compensation mandated by HUD, GNMA, FNMA,
or FHLMC.

     6.5 OTHER INTERESTS OF THE GENERAL PARTNERS AND THEIR AFFILIATES. Any
General Partner and any Affiliate of a General Partner may engage in or possess
an interest in other business ventures (unconnected with the Partnership) of
every kind and description, independently or with others including, but not
limited to, serving as general partners of other partnerships, participating in
all aspects of the Mortgage markets, which shall include, without limitation,
acquisition, origination, ownership, syndication and disposition of Mortgages,
and participating in the real estate business in all of its phases, which shall
include, without limitation, ownership, operation, financing, construction,
management, syndication and development of real property and which may include
properties competitive with a property underlying any Mortgage. The General
Partners will devote such time to the affairs of the Partnership and each other
such partnership as they, within their sole discretion, deem necessary for the
proper performance of their duties. Neither the Partnership, the Limited
Partners nor the Unitholders (except for the General Partners and their
Affiliates) shall have any rights in and to such independent ventures or the
income or profits therefrom by reason of the General Partners' position with the
Partnership. While the Partnership has available uncommitted funds to invest in
additional Mortgages, the General Partners shall not commit any Mortgage for
investment to their own account or to any non-specified Mortgage partnership
subsequently sponsored by the General Partners or their Affiliates unless the
General Partners determine that such Mortgage would not be a suitable investment
for the Partnership or that the Partnership then has insufficient funds to make
such investment. The General Partners shall make such determination on the basis
of the investment policies and objectives set forth in Section 6.2(a) hereof.
Once a good faith determination has been made that an investment opportunity is
not suitable for the Partnership, the General Partners and their Affiliates
shall have the right to take for their own account or to recommend to others any
such particular investment opportunity. Subject to the other provisions of this
Agreement, the Partnership may employ or transact business with any Person,
notwithstanding the fact that any Partner or Unitholder or any

                                      A-14
<Page>

of his Affiliates may have (or have had) an interest in or connection with such
Person, and neither the Partnership, the other Partners nor the Unitholders
shall have any rights by virtue of this Agreement in or to any income or profits
derived therefrom. Nothing herein shall be deemed to diminish the General
Partners' overriding fiduciary obligation to the Partnership or to act as a
waiver of any right or remedy the Partnership or other Partners or Unitholders
may have in the event of a breach by a General Partner of such obligation.

     6.6 OTHER TRANSACTIONS INVOLVING THE GENERAL PARTNERS AND THEIR AFFILIATES.
Except as specifically permitted in Sections 6.4 and 12.4 hereof and other
Sections of this Agreement, the General Partners are prohibited from entering
into any agreements, contracts or arrangements on behalf of the Partnership with
any General Partner or any Affiliate of any General Partner. Such prohibition
shall include, without limitation, the following: (a) neither a General Partner
nor any such Affiliate shall be given an exclusive right to sell or exclusive
employment to sell Mortgages for the Partnership; and (b) neither the General
Partner nor any such Affiliate shall receive directly or indirectly a commission
or fee (but may receive reimbursements of expenses incurred) in connection with
the reinvestment of the proceeds of the sale. In addition, in connection with
any property management or other agreement entered into by the Partnership with
any General Partner or any Affiliate of the General Partner, no rebates or
"give-ups" may be received by a General Partner or any such Affiliate, nor may
the General Partner or any such Affiliate participate in any reciprocal business
arrangements which would have the effect of circumventing any of the provisions
of this Agreement.

     Section 7. LIMITED PARTNERS AND UNITHOLDERS; CORPORATE LIMITED PARTNER;
DEPOSITARY RECEIPTS.

     7.1 CLASSES OF LIMITED PARTNERS AND UNITHOLDERS. There shall be one class
of Limited Partner Interests held by the Corporate Limited Partner and, under
certain circumstances, by Unitholders who become Investor Limited Partners.
Subject to the provisions of Section 9 of this Agreement, a Withdrawn General
Partner, or his estate or legal representatives, may also be treated as a
Limited Partner (but not as an Investor or Corporate Limited Partner) in respect
of any Interest formerly held as a General Partner in the manner specified in
Section 9.3(b) hereof.

     7.2 TRANSFERABILITY OF UNITS. The General Partners' right to accept initial
subscribers as Unitholders is set forth in Section 6.1 hereof. Each prospective
transferee of a Unit may be accepted by the General Partners as a Unitholder if
such transferee provides the General Partners with (1) information, including
name, address, status as a tax-exempt entity or non-United States person, such
information as may be necessary or appropriate to determine suitability under
applicable securities laws, and such other information as the General Partners
may request, and (2) a fee of not more than $10.00 (not including related
brokerage commissions) to reimburse the Partnership for its costs respecting the
transfer. The General Partners, in their sole discretion, may waive the transfer
fee as necessary to comply with the listing requirements of the American Stock
Exchange or another exchange if the Units are listed. The General Partners will
use their

                                      A-15
<Page>

best efforts to accept or reject a prospective transferee as a Unitholder within
the same month as they receive such information. If a prospective transferee is
not accepted by the General Partners, such prospective transferee shall have no
right to any distributions or allocations of the Partnership and shall have no
other rights, obligations or duties under this Agreement with respect to the
Partnership.

     The General Partners shall accept a prospective transferee unless a
transfer restriction applies. The General Partners shall reject a prospective
transferee if any of the following transfer restrictions applies.
Notwithstanding the foregoing, the General Partners may, in their sole
discretion, waive the restrictions on transfer in clauses (a), (b), (c), (d)
and/or (f) if necessary in order to comply with the listing requirements of the
American Stock Exchange or another exchange if the Units are listed or to avoid
causing the assets of the Partnership to be "plan assets."

     (a) The prospective transferee is not suitable under applicable federal or
state securities laws;

     (b) The prospective transferee is not a "United States person" within the
meaning of Section 7701(a)(30) of the Code, unless the General Partners
determine that such transfers would not impose unduly burdensome reporting or
withholding requirements on the Partnership;

     (c) The transfer would cause the assets of the Partnership to be "plan
assets" or the transactions contemplated hereunder to be prohibited transactions
under ERISA or the Code;

     (d) The transfer is a transfer of fewer than 100 Units, except for transfer
by will or intestacy upon the death of the transferor or by operation of law, or
unless the transferor owns fewer than 100 Units, in which case the transferor
may transfer all of such Units; or

     (e) The transfer would cause the Partnership to terminate under Section 708
of the Code.

     (f) If (1) in the opinion of Counsel to the Partnership, the transfer would
cause the Partnership to lose its status as a partnership under the Code or
would result in a termination of its taxable year or (2) in the good faith
determination of the General Partners (i) the transfer might result in a change
in the status of the Partnership to a publicly traded partnership within the
meaning of Section 7704 of the Code, and (ii) such status would have a material
adverse impact on the Unitholders. (The General Partners shall incur no
liability to the Unitholders or Limited Partners as a result of any such good
faith determination.)

     The General Partners may impose additional transfer restrictions in
accordance with Section 6.1(c) hereof. Transfers of Units shall be effective on
the date of acceptance by the General Partners.

                                      A-16

     7.3 ABSENCE OF CONTROL OVER PARTNERSHIP BUSINESS. The Limited Partners and
Unitholders hereby consent to the exercise by the General Partners of the powers
conferred on them by this Agreement. No Limited Partner or Unitholder (except
one who may also be a General Partner, and then only in his capacity as General
Partner) shall participate in or have any control over the Partnership business
or have any right or authority to act for or to bind the Partnership. No Limited
Partner or Unitholder shall have the right to have the Partnership dissolved and
liquidated or to have his Capital Contribution returned except as provided in
this Agreement.

     7.4 LIMITED LIABILITY. The liability of each Limited Partner in his
capacity as a Limited Partner shall be limited to the amount of his Capital
Contribution, and the liability of each Unitholder in his capacity as a
Unitholder shall be limited to the amount of his Subscription Price described in
Section 5.2 hereof. No Limited Partner, in his capacity as Limited Partner, and
no Unitholder, in his capacity as Unitholder, shall have any further obligations
to the Partnership or be required to contribute any capital or loan any funds to
the Partnership; provided, however, that nothing herein shall relieve the
Limited Partners or Unitholders of any liability imposed under law, including
but not limited to their liability under the Massachusetts Uniform Limited
Partnership Act for the amount of returned Capital Contributions to the extent
necessary to discharge the Partnership's liabilities to creditors who extend
credit to the Partnership during the period the Capital Contribution was held by
the Partnership. Each Unitholder assumes and agrees to pay or to reimburse the
Corporate Limited Partner with respect to any such liability of the Corporate
Limited Partner with respect to the Limited Partner Interests corresponding to
his or its Units.

     Notwithstanding the above or Section 7.6(d) hereof, no Unitholder in his
capacity as Unitholder shall be liable for acts of the Corporate Limited Partner
which constitute participation in the control of the Partnership under the
Massachusetts Uniform Limited Partnership Act unless such acts were authorized
by the Unitholders.

     7.5 ADMISSION OF INVESTOR AND SUBSTITUTE LIMITED PARTNERS. The General
Partners shall prepare and file from time to time after the initial offering of
Units, amendments to the Certificate of Limited Partnership to admit Investor

DEPOSITARY RECEIPTS.

     (a) ISSUANCE OF UNITS. Upon the contribution of the Subscription Price for
a Unit to the capital of the Partnership under Sections 5.2 and 6.1(d) hereof,
the Corporate Limited Partner shall receive the Limited Partner Interest
corresponding to such Unit, the assignment to the Unitholder and his contractual
rights under Section 7.6(b) hereof shall commence, the Units will be deemed

<Page>

Unitholder shall be deemed to have assented to all the terms and conditions of
this Agreement. Unitholders may obtain a Certificate of Depositary Receipt
evidencing their interest in the Partnership upon payment of a fee of $2.00 per
Certificate.

     (b) ASSIGNMENT AND COVENANT BY CORPORATE LIMITED PARTNER. The Corporate
Limited Partner, by the execution of this Agreement, irrevocably transfers and
assigns, to the extent permitted by the Massachusetts Uniform Limited
Partnership Act, to the Unitholders all of the Corporate Limited Partner's
rights and interest in and to the Limited Partner Interests corresponding to the
Units, including the right to distributions, including liquidating distributions
of the Partnership, as of the time of release to the Partnership of the
Subscription Price for each such Unit. At the same time, the Corporate Limited
Partner, by the execution of this Agreement, agrees and covenants that it will
exercise any other rights with respect to each Limited Partner Interest solely
in favor of, in the interest of, and at the direction of the Unitholder whose
Unit corresponds to such Limited Partner Interest. The Corporate Limited Partner
shall remain a Limited Partner of the Partnership with respect to the Limited
Partner Interests corresponding to the Units, notwithstanding the assignment of
its rights and interests under this Section 7.6(b). The Corporate Limited
Partner shall have a fiduciary responsibility for the safekeeping and use of all
funds and assets of the Unitholders, whether or not in the Corporate Limited
Partner's possession or control, and the Corporate Limited Partner shall not
employ or permit another to employ such funds or assets in any manner except for
the exclusive benefit of the Unitholders. In addition, the Unitholders shall not
be permitted to contract away the fiduciary duty owed to the Unitholders by the
Corporate Limited Partner under the common law of agency.

     (c) CONSENT TO ASSIGNMENT AND COVENANT. The General Partners, by the
execution of this Agreement, irrevocably consent to and acknowledge that (1) the
foregoing assignment and covenant by the Corporate Limited Partner to the
Unitholders with respect to the Corporate Limited Partner's rights and interest
in the Limited Partner Interests corresponding to the Units as described above
is effective and (2) the Unitholders are intended to be assignees of record and
third party beneficiaries of all rights and privileges of the Corporate Limited
Partner in respect of the Limited Partner Interests corresponding to their
Units. The General Partners covenant and agree that, in accordance with the
foregoing assignment and covenant of the Corporate Limited Partner, all the
Corporate Limited Partner's rights and privileges in respect of the underlying
Limited Partner Interests may be exercised by the Unitholders on an
Interest-by-Interest basis or, if not permitted to be exercised by the
Unitholders under Massachusetts law, then by the Corporate Limited Partner on an
Interest-by-Interest basis as provided by Section 7.6(e) hereof.

     (d) NO LIABILITY OF CORPORATE LIMITED PARTNER. The Corporate Limited
Partner shall not be liable to any Unitholder for any action or nonaction by it
taken or omitted: (i) in good faith and without negligence or misconduct and (2)
in reliance upon advice, written notice, request or direction from a Unitholder
believed by it to be genuine and to have been signed or presented by the proper
person or persons. The Unitholders and Investor Limited Partners except to the
extent set forth in Section 6.3 hereof and not the Corporate Limited Partner
shall be liable to the Partnership or any third party for any

                                      A-18
<Page>

obligations for which limited partners are liable under this Agreement or
applicable law in accordance with Section 7.4, and each Unitholder assumes, and
agrees to pay or to reimburse the Corporate Limited Partner with respect to, any
such liability applicable to his Unit for which such Corporate Limited Partner
would be entitled to indemnification under Section 6.3 hereof.

     (e) VOTING. In the event that the Unitholders are not permitted to exercise
any voting or similar rights in the Partnership directly, the Corporate Limited
Partner shall canvass the preferences of all Unitholders on all matters
submitted to a vote of the Limited Partners, and the Corporate Limited Partner
shall vote each underlying Limited Partner Interest only in accordance with the
directions of the Unitholder whose Unit corresponds to such Interest, with each
Unit (and, therefore, each Limited Partner Interest) entitled to one vote. The
Corporate Limited Partner shall only vote the Limited Partner Interests held by
it in accordance with, and to the extent of, written instructions received from
the Unitholders. All voting shall be conducted in accordance with Section 13
hereof.

     (f) CALLING MEETINGS. Unitholders, individually or collectively with
Investor Limited Partners, owning directly or indirectly 10% or more of the
outstanding Limited Partner Interests, may exercise the rights of Limited
Partners to call a meeting by written notice to the Corporate Limited Partner
and the General Partners. Within ten business days after receipt of such notice,
the Corporate Limited Partner shall request a meeting in accordance with the
procedures set forth in Section 13.1 hereof.

     (g) ALLOCATIONS AND DISTRIBUTIONS. The portion of Profits or Losses for Tax
Purposes and distributions which shall be credited to the account of the
Corporate Limited Partner for the benefit of Unitholders shall be allocated and
apportioned among the Unitholders in the same manner as Profits or Losses for
Tax Purposes and distributions are allocated and apportioned among Limited
Partners with respect to the underlying Limited Partner Interests in Section 8
of this Agreement.

     (h) EXCHANGE OF UNITS FOR LIMITED PARTNER INTERESTS. Any Unitholder who
desires to exchange all of his Units for Limited Partner Interests may do so by
delivering to the Partnership applications (which are available upon request
from the Partnership), and the payment of a fee of the lesser of $50.00 or
actual costs per transaction, for legal and administrative costs and filing
fees. The effective date of any such exchange shall be the first day of the
month following the date as of which the General Partners file an amendment to
the Certificate of Limited Partnership listing the name of such Unitholder as an
Investor Limited Partner. Such an amendment shall be filed no later than 15 days
after the completion of any fiscal quarter of the Partnership in which a Unit is
exchanged for a Limited Partner Interest. Persons who effect such conversion
will receive one Limited Partner Interest for each Unit they exchange and will
not be able to re-exchange Limited Partner Interests for Units. Units which have
been converted into Limited Partner Interests will be cancelled and will not be
reissued. If Units shall be exchanged for Limited Partner Interests as a result
of a requirement imposed by the General Partners under Section 6.1(c) hereof or
by applicable law, there shall be no fee charged by the Partnership with respect
to the transaction.

the contrary that may be expressed or implied in this Agreement, the interests
of all of the General Partners, taken together, in each item of Partnership

<Page>

     (g) QUALIFIED INCOME OFFSET. Notwithstanding anything in Section 8.1(a) to
the contrary, if, at the end of any taxable year, any Partner has a negative
Capital Account (beyond the amount of such negative Capital Account such Partner
is required to restore to the Partnership) as a result of (a) allocations of
loss or deduction (other than those attributable to nonrecourse debt of the
Partnership) to such Partner pursuant to Code section 706(d) or Treasury
Department Regulations section 1.751-(b)(2)(ii) or (b) distributions to such
Partner, which allocations or distributions could not reasonably have been
expected to occur as of the end of the prior taxable year (such negative Capital
Account referred to hereafter as a "Qualified Income Offset Account"), then
items of income and gain shall be allocated to such Partner (or among all
Partners in proportion to their respective Qualified Income Offset Accounts) to
the extent of such Qualified Income Offset Account as quickly as possible. The
allocation set forth herein (the "Regulatory Allocation") is intended to comply
with certain requirements of Regulations Section 1.704-1(b). Notwithstanding any
other provisions of this Section 8 (other than the Regulatory Allocation), the
Regulatory Allocation shall be taken into account in allocating other Profits
for Tax Purposes, Losses for Tax Purposes and items of income, gain, loss and
deduction among the Partners and Unitholders so that, to the extent possible,
the net amount of such allocations of other Profits for Tax Purposes, Losses for
Tax Purposes and the other items and the Regulatory Allocation to each Partner

such Partner or Unitholder if the Regulatory Allocation had not occurred.

8.1(a) to the contrary, interest income of the Partnership with respect to
Subscription Prices for Units on account of the period of time prior to the

respect to such Unit attributable to the receipt by the Partnership of such
interest with respect to such Subscription Price.

     8.2 DISTRIBUTABLE CASH FLOW.

     Distributable Cash Flow of the Partnership shall be distributed
ninety-seven percent (97%) to the class comprised of the Limited Partners and
three percent to the class comprised of the General Partners, except that a
portion of Distributable Cash Flow shall be distributed with respect to each
Unit in the amount, if any, equivalent to the interest received by the
Partnership net of escrow expense with respect to the Subscription Price for
such Unit on account of the period of time prior to the initial closing of the
sale of Units.

     8.3 PROCEEDS OF CAPITAL TRANSACTIONS AND THE TERMINATING CAPITAL
TRANSACTION.

Terminating Capital Transaction and the winding up of the affairs of the
Partnership shall be distributed as follows:

to (or if less than, in proportion to) the aggregate of the then positive

     8.4 SPECIAL PROVISIONS FOR ALLOCATIONS AND DISTRIBUTIONS.

     (a) Subject to the provisions of Sections 8.4(d) and 8.4(e) hereof, and to
allocation (if any) to Partners in accordance with their respective Capital
Accounts of Profits and Net Cash Proceeds from the Terminating Capital
Transaction pursuant to Sections 8.1(c) FIRST and 8.3(b) FIRST, all Profits or

as follows: (1) among the Limited Partners, in proportion to their respective
number of Interests, and (2) to the General Partners, in proportion to their
respective Invested Capital.

     (b) All Profits or Losses for Tax Purposes allocated to, and distributions
of cash made to, the Partners shall be credited or charged, as the case may be,
to their Capital Accounts as of the date as of which such Profits or Losses for
Tax Purposes are allocated and the date as of which distributions of cash are
made. All distributions made to the Partners pursuant to the provisions of
Section 8.2 hereof shall be treated as having been made and charged to their
respective Capital Accounts prior to the allocation of Profits or Losses for Tax
Purposes pursuant to Section 8.1; distributions under Section 8.3(a) shall be
treated as having been made and charged to their respective Capital Accounts
prior to the allocation of Profits for Tax Purposes pursuant to Section 8.1(b)
and prior to the allocation of Losses for Tax Purposes pursuant to Section
8.1(d); distributions under Section 8.3(b) shall be treated as having been made
and charged to their respective Capital Accounts after the allocation of all
Profits or Losses for Tax Purposes pursuant to Section 8.1. The Profits or
Losses for Tax Purposes of the Partnership allocated among the Partners pursuant
to Section 8.1(a) shall be credited or charged to their respective Capital
Accounts prior to the allocation of Profits or Losses for Tax Purposes of the
Partnership pursuant to Sections 8.1(b), (c), (d) and (e).

     (c) The Partnership shall make distributions of Distributable Cash Flow for
each quarter commencing with the quarter in which the initial closing of the
sale of Units occurs. Within 60 days after the completion of each of the first
three quarters of each of the Partnership's fiscal years, the Partnership will
make a distribution of Distributable Cash Flow, which distribution will be based
upon an estimate by the General Partners of the Partnership's total
Distributable Cash Flow for such year. Within 60 days after the end of each
fiscal year, the Partnership's Distributable Cash Flow for such year will be
determined and, after giving effect to the amount of Distributable Cash Flow
previously distributed, the remainder will then be distributed.

     (d) All Profits or Losses for Tax Purposes allocated pursuant to Section
8.1(a) and all distributions made pursuant to Section 8.2, if any, to the class
of Limited Partners based upon transactions of the Partnership during any fiscal
years in which Units are initially sold, shall be allocated among the Limited
Partners as follows: (i) each such

                                      A-24
<Page>

fiscal year shall be divided into 365 equal portions (or, if less, a number of
portions equal to the number of days in the fiscal year) and the operations of
the Partnership shall be deemed to have occurred on a pro rata basis over each
of such portions irrespective of the actual operations of the Partnership; (ii)
such allocations and distributions shall be made with respect to each Interest
on the basis of the number of such portions during such fiscal year such
Interest was outstanding. An Interest shall be deemed outstanding from the date
of acceptance by the General Partners of the subscription therefor.

     (e) In the event that a Unit or Interest is transferred in any period
following the last month in which Units are initially sold, (i) Distributable
Cash Flow with respect to the fiscal quarter first commencing after the last
month in which Units are initially sold and during which the transfer occurs
shall be distributed solely to the Unitholder or Investor Limited Partner
recognized as such under this Agreement on the last day of the fiscal quarter
irrespective of the number of transfers of such Unit or interest during such
fiscal quarter; (ii) the Profit or Loss for Tax Purposes allocated under Section
8.1(a) to such Unit or Interest with respect to such fiscal year shall be
divided into 365 equal portions (or, if less, a number of portions equal to the
number of days in the fiscal year) and allocated one portion to the Person who
owned the Unit or Interest each day during the fiscal year in which the transfer
occurred irrespective of the actual operations of the Partnership; (iii) Net
Cash Proceeds and Profit or Loss For Tax Purposes arising from the same Capital
Transaction (or the Terminating Capital Transaction) shall be distributed and
allocated, respectively, to the Unitholder or Investor Limited Partner
recognized as such under this Agreement as of the date of such Capital
Transaction (or the Terminating Capital Transaction); and (iv) Net Cash Proceeds
and Profit or Loss for Tax Purposes not received or realized, as the case may
be, upon a Capital Transaction (or the Terminating Capital Transaction), but
later received or realized, as the case may be, by the Partnership as a result
of an installment or other deferred payment sale, shall be distributed and
allocated, respectively, to the Unitholder or Investor Limited Partner
recognized as such under this Agreement as of the dates such Net Cash Proceeds
and Profit or Loss are received or realized, as the case may be, by the
Partnership. The General Partner, without the consent of any Unitholder or
Limited Partner, shall have the authority to modify the method of distributing
Cash Flow and Net Cash Proceeds and of allocating corresponding Profit or Loss
for Tax Purposes in the case of transfers of Units or Interests provided that
(i) any modifications shall be prospective only, (ii) such modifications shall
apply uniformly to all Units and Interests, (iii) notice shall be provided to
all Unitholders and Limited Partners at least 90 days before the effective date
of any such modification arid (iv) no such modification shall be permitted if it
would have an adverse effect on any Unitholder or Limited Partner without the
Consent of a majority in interest of the Limited Partners.

     (f) Any allocation or distribution with respect to a Limited Partner
Interest shall be made directly to the Unitholder of the Unit corresponding to
such Interest, if any.

     (g) If an amount paid or deemed paid to the General Partners or their
Affiliates as a fee or payment described in Section 6.4 hereof is a distribution
to a general partner in its capacity as a partner and not a guaranteed payment
as defined in Section 707(c) of the Code or a payment to a partner not acting in
his capacity as a partner under

                                      A-25
<Page>

Section 707(a) of the Code, the General Partners shall be allocated an amount of
Partnership gross income equal to such payment and its Capital Account shall be
reduced to reflect the distribution. For purposes of Sections 8.1, 8.2 and 8.3,
Profits and Losses for Tax Purposes shall be determined after making any
allocation required by this Section 8.4(g).

     (h) All amounts paid with respect to any Unit as sales commissions shall be
allocated to the particular Unit with respect to which they are paid and the
Capital Account for such Unit shall be reduced to reflect such allocation.

     8.5 RETURN OF CAPITAL CONTRIBUTIONS. All Partners and Unitholders shall
look solely to the assets of the Partnership for the return of Capital
Contributions or any other distributions with respect to their Interests. If the
assets remaining after payment or discharge, or provisions for payment or
discharge, of its debts and liabilities are insufficient to return the Capital
Contributions or to make any other distributions to the Partners and
Unitholders, no Partner or Unitholder shall have any recourse against the
personal assets of any other Partner or Unitholder for that purpose, except to
the limited extent set forth in Section 6.3 hereof.

     8.6 REINVESTMENT OF NET CASH PROCEEDS. The Partnership shall not reinvest
Cash Flow in Mortgages. The Partnership may reinvest Net Cash Proceeds only as
provided in Section 6.1(c) hereof. In the event reinvestment is permitted under
Section 6.1(c) hereof, the General Partners may elect, in their sole discretion
based upon real estate, Mortgage and MBS market conditions then in effect,
either to distribute all or any portion of the cash available for such
reinvestment or to reinvest such cash in Mortgages or MBS or in investments of
the type referred to in Section 6.2(a) if the General Partners are unable to
identify immediately suitable Mortgages or MBS for reinvestment. Notwithstanding
the foregoing, if the transaction giving rise to such cash shall create any
federal and state income tax liability for Investor Limited Partners or
Unitholders which are not Tax-Exempt Entities, no such cash shall be reinvested
unless sufficient Net Cash Proceeds are distributed to enable Investor Limited
Partners and Unitholders to pay such taxes (assuming the Investor Limited
Partners and Unitholders are taxable at an overall combined rate of 32% on
ordinary income and 32% on long-term capital gains).

     8.7 RETURN OF UNINVESTED CAPITAL CONTRIBUTIONS. In the event that any
portion of any Limited Partner's Capital Contribution is not invested or
committed for investment in Mortgages by the Partnership within 24 months from
the date of the Partnership's Prospectus (except for any amounts utilized as
necessary operating capital of the Partnership), such portion of Capital
Contributions shall promptly be distributed by the Partnership as a return of
capital. For the purpose of this Agreement, funds will be deemed to have been
committed to investment and will not be returned to the extent writ- ten
agreements in principle, commitment letters, letters of intent or understanding,
option agreements or any similar contracts or understandings were at any time
executed but not terminated during the aforesaid 24-month period, regardless of
whether any such investment is or is not ultimately consummated, and to the
extent any funds have been reserved to make contingent payments in connection
with any property, regardless of whether any such payments are or are not
ultimately made. In the event that any Capital

                                      A-26
<Page>

Contributions shall be returned pursuant to this Section, the respective Capital
Contributions (and Invested Capital) of the Investor Limited Partners and
Unitholders shall be reduced by the amount of such distribution.

     Section 9. WITHDRAWAL OF GENERAL PARTNERS.

     9.1 VOLUNTARY WITHDRAWAL. Any General Partner may Voluntarily Withdraw as a
General Partner from the Partnership at any time provided that (a) the General
Partner shall have given sixty (60) days prior written notice thereof to the
Limited Partners, (b) the Partnership shall have received the opinion of Counsel
to the Partnership to the effect that such Withdrawal will not constitute a
termination of the Partnership or otherwise materially adversely affect the
status of the Partnership for federal income tax purposes, and (c) if the
General Partner proposing to Withdraw is then the sole General Partner, or if
such Voluntary Withdrawal shall require the admission of a new General Partner
in order to preserve the status of the Partnership as a partnership for federal
income tax purposes, a new General Partner shall have been selected who, or
which, (i) shall have stated willingness to be admitted, (ii) shall satisfy the
then applicable provisions of the Code and any applicable procedures,
regulations, rules and rulings (including published private rulings) thereunder,
including applicable net worth requirements so that the Partnership shall be
classified as a partnership for tax purposes, and (iii) shall have received the
specific written consent of any remaining General Partner and of Limited
Partners holding not less than a majority of the Limited Partner Interests with
respect to such admission. Notwithstanding the foregoing, in no event shall
either Krupp Plus Corporation or Mortgage Services Partners Limited Partnership
Voluntarily Withdraw as a General Partner from the Partnership prior to December
31, 1991.

     9.2 INVOLUNTARY WITHDRAWAL. A General Partner shall be deemed to have
Involuntarily Withdrawn as a General Partner from the Partnership upon the
occurrence of any of the following events: (a) in the case of Mortgage Services
Partners Limited Partnership or an additional or Substitute General Partner
which is a partnership, upon the death, physical or mental incapacity (as
determined by certificate of a licensed physician), dissolution or bankruptcy of
all general partners of such partnership, (b) in the case of Krupp Plus
Corporation or an additional or Substitute General Partner which is a
corporation, the filing of a certificate of dissolution, or its equivalent, for
such General Partner or the revocation of its charter, (c) the removal of the
General Partner pursuant to a vote of the Limited Partners made in accordance
with Section 13 of this Agreement, (d) the making of an assignment for the
benefit of creditors, the filing of a voluntary petition in bankruptcy, or an
adjudication of bankruptcy, or (e) any other event which constitutes an event of
withdrawal under the Act as then in effect.

     9.3 CONSEQUENCES OF WITHDRAWAL.

     (a) Upon the Withdrawal of any General Partner, the Withdrawn General
Partner or his estate or legal representatives shall be entitled to receive from
the Partnership (i) any positive balance in his or its Capital Account (as
adjusted to the date of such Withdrawal), (ii) any amounts due and owing to it
or him by the Partnership less any amounts due and owing by it or him to the
Partnership, and (iii) the remaining balance, if

                                      A-27
<Page>

any, of fees payable as and when due pursuant to this Agreement or any other
written agreements between the Partnership and such General Partner in his
capacity as General Partner; however, the Withdrawn General Partner shall not be
entitled to any such fees which had not yet been earned by him prior to his
Withdrawal. The right of a General Partner, his estate or legal representatives
to payment of said amounts and fees shall be subject to any claim for damages
which the Partnership or any Partner may have against such General Partner, his
estate or legal representative if such Withdrawal is in contravention of this
Agreement. Valuation of a Withdrawn General Partner's Interest shall be in
accordance with the provisions of Section 13.4 hereof.

     (b) Each General Partner hereby covenants and agrees, in the event of his
Withdrawal, to transfer to a Substitute General Partner selected as provided in
Section 9.5 hereof or to the remaining General Partner or General Partners, such
portion, if any, of his General Partner Interest as may be required to assure
that the Partnership will meet the minimum general partnership interest
requirement for the continued treatment of the Partnership as a partnership
under the then applicable provisions of the Code and any applicable procedures,
regulations, rules and rulings (including published private rulings) thereunder.
Any such transfer will be made in consideration of the payment by the Substitute
General Partner or the remaining General Partner or Partners to the Withdrawn
General Partner, his estate or legal representatives, of the fair market value
of such interest. Such payments shall be in addition to any amounts payable
pursuant to Section 9.3(a) hereof by the Partnership. Any portion of such
Withdrawn General Partner's Interest which is not transferred to a Substitute
General Partner as aforesaid may be purchased by the Partnership. In the event
of such a purchase, the Interest of the Withdrawn General Partner to be
purchased shall be valued in accordance in Section 13.4 hereof as though such
Withdrawn General Partner had been removed pursuant to Section 13.2 hereof, and
shall be paid for by delivery of a note of the Partnership which shall be
unsecured and non-interest bearing with principal payable, if at all, from
distributions which the Withdrawn General Partner otherwise would have received
under this Agreement had such Withdrawn General Partner not withdrawn. Any
portion of the Withdrawn General Partner's interest which is not required to be
transferred as aforesaid and which the Partnership does not elect to purchase
may be retained by such Withdrawn General Partner, or its estate or legal
representatives as appropriate. In such event, the Withdrawn General Partner, or
its estate or legal representatives, shall be treated as a Limited Partner in
the Partnership in respect to any such retained Interest.

     (c) If the Withdrawal of a General Partner shall occur as part of a removal
and replacement of such General Partner effected in accordance with Section 13
hereof, the provisions of said Section 13 shall govern to the extent (if any)
that the provisions of said Section 13 are inconsistent with the provisions of
this Section 9.3.

     9.4 LIABILITY OF WITHDRAWN GENERAL PARTNER. If the business of the
Partnership is continued after Withdrawal of a General Partner, the Withdrawn
General Partner, his estate and legal representatives shall remain liable for
all obligations and liabilities incurred by him while a General Partner and for
which he was liable as a General Partner, but shall be free of any obligation or
liability incurred on account of or arising from the

                                      A-28
<Page>

activities of the Partnership from and after the time such Withdrawal shall have
become effective.

     9.5 CONTINUATION OF PARTNERSHIP BUSINESS.

     (a) PROCEDURE IF THERE IS A REMAINING GENERAL PARTNER. Upon the Involuntary
Withdrawal of a General Partner, the remaining General Partner or Partners, if
any, shall promptly notify the Limited Partners and Unitholders of such
Involuntary Withdrawal. In the event of an Involuntary or Voluntary Withdrawal
of a General Partner the remaining General Partner or Partners must elect to
continue the Partnership business. If at any time Krupp Plus Corporation or a
successor General Partner with substantial net worth shall Withdraw as a General
Partner, the remaining General Partners or Partner, if any, may (but shall not
be obligated to) propose for admission a Substitute General Partner or General
Partners, unless a Substitute General Partner shall have already been proposed
by the Limited Partners pursuant to Section 13 hereof. Any such proposed
Substitute General Partner shall, with the specific written consent of the other
General Partner and of the Limited Partners with respect to not less than a
majority of the Limited Partner Interests, become a Substitute General Partner
upon his or its execution of this Agreement.

     (b) PROCEDURE IF THERE IS NO REMAINING GENERAL PARTNER. If, following the
Withdrawal of a General Partner, there is no remaining General Partner or
Substitute General Partner, any Limited Partner may notify the other Limited
Partners and Unitholders of such circumstances and may propose for admission a
Substitute General Partner, unless a Substitute General Partner shall have
already been proposed by the Limited Partners pursuant to Section 13 hereof. Any
Substitute General Partner pro- posed by such Limited Partners pursuant to this
Section 9.5(b) or Section 13.2 hereof, shall, with the specific written consent
of the Limited Partners with respect to not less than a majority of the Limited
Partner Interests, become a Substitute General Partner upon his or its execution
of this Agreement and may thereupon elect to continue the Partnership business.
If no Substitute General Partner has received the consent of the Limited
Partners with respect to not less than a majority of the Limited Partner
Interests, executed this Agreement, and elected to continue the Partnership
business within one hundred eighty (180) days from the date of the last
remaining General Partner's Withdrawal, then the Partnership shall thereupon
terminate.

     Section 10. ASSIGNMENT OF LIMITED PARTNER INTERESTS.

     10.1 WITHDRAWAL OF A LIMITED PARTNER. Subject to compliance with this
Agreement, a Limited Partner may withdraw from the Partnership only by assigning
or otherwise transferring his or its Interest as specified in this Section 10.
Such withdrawal of a Limited Partner shall not dissolve or terminate the
Partnership. In the event of a Limited Partner's withdrawal because of death,
legal incompetence, dissolution or other termination, the estate, legal
representative or successor of such withdrawn Limited Partner shall be deemed to
be the assignee of such withdrawn Limited Partner's Interest and may become a
Substitute Limited Partner upon compliance with the provisions of Section 10.3
hereof.

                                      A-29
<Page>

     10.2 ASSIGNMENT. Units of Depositary Receipts may be Assigned in accordance
with Section 7.2 hereof. Limited Partner Interests of the Corporate Limited
Partner which correspond to Units may be Assigned in accordance with Section
7.6(b) hereof. Other Limited Partner Interests may be Assigned only in
accordance with this Section 10.2 and Section 10.4. Such Limited Partner
Interests may be Assigned provided there shall be filed with the Partnership, in
form satisfactory to the General Partners, a duly executed counterpart of the
instrument making such Assignment and such instrument (a) evidences the written
acceptance by the assignee of all of the terms and provisions of this Agreement,
(b) represents that such Assignment was made in accordance with all applicable
laws and regulations (including, without limitation, such minimum investment and
investor suitability requirements as may then be applicable under state
securities laws), and (c) is accompanied by a fee of the lesser of $50.00 or
actual costs to reimburse the Partnership for its costs respecting the
Assignment.

     10.3 SUBSTITUTION. An assignee of a Limited Partner Interest assigned in
accordance with the provisions of Section 10.1 or 10.2 hereof shall become a
Substitute Limited Partner if:

     (a) such assignee executes an instrument reasonably satisfactory to the
General Partners accepting and adopting the terms and provisions of this
Agreement, including the power of attorney as provided in Section 15(d) hereof;

     (b) in the case of Assignments other than by operation of law, the assignor
states his intention in writing to have his assignee become a Substitute Limited
Partner; and

     (c) the General Partners, in their sole discretion, consent in writing to
such substitution (which consent may be withheld).

     If all of the conditions of this Section 10.3 and either Section 10.1 or
10.2 shall have been met, the assignee of a Limited Partner Interest shall
become a Substitute Limited Partner as of the date as of which the General
Partners consent in writing to his admission to the Partnership as a Substitute
Limited Partner, which consent may be evidenced by the filing of an amendment to
the Certificate of Limited Partnership listing the name of such Substitute
Limited Partner. Such an amendment shall be filed no later than 15 days after
the completion of any fiscal quarter of the Partnership in which a Substitute
Limited Partner is admitted to the Partnership.

     An assignee of a Limited Partner Interest who does not become a Substitute
Limited Partner in accordance with this Section 10.3 and who desires to make a
further Assignment of his Interest shall be subject to all the provisions of
Sections 10.2, 10.3 and 10.4 hereof, to the same extent and in the same manner
as any Limited Partner desiring to make an Assignment of his Interest. Failure
or refusal of the General Partners to admit an assignee of a Limited Partner
Interest as a Substitute Limited Partner shall in no way affect the right of
such assignee to receive the share of the Profits or Losses for Tax Purposes and
distributions of Cash Flow and Net Cash Proceeds to which his predecessor in
interest would have been entitled in accordance with Section 8 hereof.

                                      A-30

     10.4 PROHIBITED ASSIGNMENT. No Limited Partner Interests may be Assigned or
otherwise transferred:

     (a) to a non-United States person unless the General Partners determine
that such transfer would not impose unduly burdensome reporting or withholding
requirements on the Partnership;

     (b) to a minor or incompetent (unless a guardian, custodian or conservator
has been appointed to handle the affairs of such Person);

     (c) to any Person if the transfer is a transfer of fewer than 100 Limited
Partner Interests, except for a transfer by will or intestacy upon the death of
the transferor or by operation of law, or unless the transferor owns fewer than
100 Limited Partner Interests, in which case the transferor may transfer all of
such Limited Partner Interests;

     (d) to any Person if, in the opinion of Counsel to the Partnership, such
transfer would result in the assets of the Partnership being "plan assets" or
the transactions hereunder being prohibited transactions under ERISA or the
Code; or

     (e) to any Person if (1), in the opinion of Counsel to the Partnership,
such transfer would result in the termination under the Code of the
Partnership's taxable year or of its status as a partnership, or (2) the General
Partners determine in good faith that (i) such transfer might result in a change
in the status of the Partnership to a publicly traded partnership within the
meaning of Section 7704 of the Code, and (ii) such status would have a material
adverse impact on the Unitholders. (The General Partners shall incur no
liability to the Unitholders or Limited Partners as a result of any such good
faith determination.)

     The General Partners may waive clause (c) above if, in their discretion,
application of such restrictions would impose a hardship on the holder or would
not be in compliance with the listing requirements of the American Stock
Exchange or another exchange upon which Units may be listed.

     Any such attempted Assignment without the express written consent of the
General Partners shall be void and ineffectual and shall not bind the
Partnership. In the case of a proposed Assignment which is prohibited solely
under clause (e) above, however, the Partnership shall be obligated to permit
such Assignment to become effective if and when, in the opinion of Counsel to
the Partnership, such Assignment would no longer have any of the adverse
consequences under the Code which are specified in that clause.

     10.5 STATUS OF AN ASSIGNING LIMITED PARTNER. Any Limited Partner (other
than the Corporate Limited Partner) who shall Assign all of his Interest shall
cease to be a Limited Partner of the Partnership and shall no longer have any of
the rights or privileges of a Limited Partner, except that unless and until a
Substitute Limited Partner is admitted in his stead, such assigning Limited
Partner shall retain the statutory rights of an assignor of a limited partner
interest under the Act.

     Section 11. DISSOLUTION AND WINDING-UP.

     11.1 EVENTS CAUSING DISSOLUTION. The Partnership shall be dissolved and its
affairs wound up on the first to occur of the following:

     (a) the Withdrawal of any General Partner, unless the remaining General
Partner or General Partners, if any, or a Substitute General Partner admitted in
accordance with Section 9.5 or Section 13 hereof, agrees to continue the
Partnership business pursuant to Section 9.5; or

     (b) an election to dissolve the Partnership made in writing by the General
Partners with the Consent of a majority in interest of the Limited Partner
Interests, or, subject to compliance with Section 13 hereof, made by a majority
in interest of the Limited Partner Interests, without action by the General
Partners; or

     (c) the sale or other disposition of all or substantially all of the
Mortgages unless the General Partners elect to continue the Partnership business
for the purpose of the receipt and collection of a note and payments thereon or
the collection of any other consideration to be received in exchange for the
Mortgages (which activities shall be deemed to be a part of the Terminating
Capital Transaction and the winding-up of the affairs of the Partnership); or

     (d) the expiration of the Partnership term; or

     (e) any other event which causes the dissolution and/or winding up of the
Partnership under the Act to the extent not otherwise provided herein.

     11.2 DISTRIBUTIONS UPON DISSOLUTION. Upon the dissolution of the
Partnership, the General Partners, or if there are none, such other Person
required by law to wind up the Partnership's affairs, shall proceed with the
liquidation of the Partnership (including, without limitation, the sale or other
disposition of any remaining Mortgages and cancellation of the Certificate of
Limited Partnership), and the net proceeds of such liquidation shall be first
applied to the payment of debts and other obligations of the Partnership, and
all remaining net proceeds, if any, shall be applied and distributed in
accordance with the provisions of Section 8.3(b) hereof. During the period of
dissolution and winding-up of the Partnership, the General Partners or any
Person performing such actions may exercise all of the powers granted to the
General Partners herein, and they may adopt such plan, method or procedures as
they may deem reasonable in order to effectuate an orderly winding-up. If the
General Partners shall perform the foregoing functions, they shall be
compensated therefor as provided in Section 6.4 and 8 hereof, and if such
functions shall be performed by Persons other than the General Partners, such
Persons shall be entitled to reasonable compensation from the Partnership for
their services.

in such commercial bank account or accounts as shall be designated by the

names and addresses of all Limited Partners and Unitholders, together with their
respective Capital Contributions and Subscription Prices, to any Limited Partner
or Unitholder who makes a written request therefor to the Partnership, provided
such Partner or Unitholder shall pay the cost of reproducing and delivering such
list. Except to the extent requested by any Limited Partner or Unitholder, the
General Partners shall have no obligation to deliver or mail a copy of the
Partnership's Certificate of Limited Partnership or any amendment thereto to the
Limited Partners or Unitholders. Each Limited Partner shall also have the right
to obtain from the General Partners from time to time upon reasonable demand:

income tax purposes and otherwise in accordance with generally accepted
accounting principles applied in a consistent manner. Except as otherwise
provided herein, whenever a proportionate part of the Profits or Losses for Tax
Purposes of the Partnership is credited or charged to a Partner's Capital
Account, every item of income, gain, loss or deduction entering into the
computation of such Profits or Losses shall be considered either credited or
charged, as the case may be,

                                      A-33
<Page>

and every item of credit or tax preference related to such Profits or Losses and
applicable to the period during which such Profits or Losses were realized shall
be allocated to such Capital Account in the same proportion.

     12.4 PARTNERSHIP EXPENSES.

     (a) The Partnership shall reimburse the General Partners and their
Affiliates for organizational and offering expenses incurred by the General
Partners and such Affiliates, provided that in no event shall the amount of
organizational and offering expenses paid directly or indirectly by the
Partnership exceed 2% of the gross proceeds of the offering of Units, and the
General Partners shall pay for any organizational and offering expenses in
excess of such 2% amount. For purposes hereof, "organizational and offering
expenses" shall mean those expenses incurred in connection with, and in
preparing the Partnership for, qualification under the federal and state
securities laws and subsequently offering and distributing the Units to the

     (b) Subject to the foregoing, the Partnership shall pay all expenses (which
expenses shall be billed directly to the Partnership) of the Partnership which
may include but are not limited to (1) all costs of personnel (excluding rent or
depreciation, utilities, capital equipment, and other administrative items)
employed full- part-time by the Partnership and involved in the business of the
Partnership and allocated pro rata to their administrative services performed on
behalf of the Partnership, including Persons who may also be officers or
employees of the General Partners or their Affiliates (other than Controlling
Persons); (ii) all costs of borrowed money, taxes on Mortgages and other taxes
applicable to the Partnership; (iii) legal, audit, accounting, brokerage and
other fees; (iv) printing, engraving and other expenses and taxes incurred in
connection with the issuance, distribution, transfer, registration and recording
of documents evidencing ownership of an Interest or Unit or in connection with
the business of the Partnership; (v) fees and expenses paid to independent

of Mortgages; (vii) expenses of organizing, revising, amending, converting,
modifying or terminating the Partnership; (viii) expenses in connection with
distributions made by the Partnership to, and communications and bookkeeping and
clerical work necessary in maintaining relations with, Limited Partners and

evidences of ownership of Limited Partner Interests or Units and reports of
meetings of the Partnership, and of preparation of proxy statements and
solicitations of proxies in connection therewith; (ix) expenses in connection
with preparing and mailing reports required to be furnished to Limited

                                      A-34
<Page>

Partners and Unitholders for investor, tax reporting or other purposes, or which

Unitholders to be in the best interests of the Partnership; (x) accounting,
computer, statistical or bookkeeping costs necessary for the maintenance of the
books and records of the Partnership; and (xi) the cost of preparation and
dissemination of the informational material and documentation relating to
potential sale or other disposition of Partnership Mortgages. Other than as
specifically described above in this Section and in Section 6.4 hereof, the
Partnership shall not pay the General Partners for any other items generally
considered to be the General Partners' overhead and expenses.

     (c) Except for organizational and offering expenses and the 1.5% allowance
for non-accountable expenses connected with the acquisition of Mortgages
provided in Section 6.4(b), the Partnership shall not reimburse the General
Partners or their Affiliates except for reimbursement of the actual cost to the
General Partners or their Affiliates of goods, materials and services used for
or by the Partnership and obtained from Persons unaffiliated with the General
Partners and their Affiliates; provided, however, subject to the limitations
stated below, the General Partners and their Affiliates may receive
reimbursement for the administrative services necessary to the prudent operation
of the Partnership, such as legal, accounting, computer, transfer agent and
other services which could be performed directly for the Partnership by
independent parties. The amounts charged to the Partnership for such
administrative services will not exceed the lesser of (i) the actual costs to
the General Partners or their Affiliates, or (ii) 90% of those which the
Partnership would be required to pay to independent parties for comparable
services in the same or comparable geographic locations. As part of the
Partnership's annual report to the Limited Partners and Unitholders, an itemized
breakdown will be included of such reimbursements, all of which shall be
verified by the Accountants. Such verification shall at minimum provide (i) a
review of the records of individual employees, the costs of whose services were
reimbursed, and (ii) a review of the specific nature of the work performed by
each such employee. The methods of verification shall be performed in accordance
with generally accepted auditing standards and shall accordingly include such
tests of the accounting records and such other auditing procedures which the
Accountants consider appropriate in the circumstance. The additional costs of
such verification will be itemized by the Accountants on a
partnership-by-partnership basis and may be reimbursed to the General Partners
and their Affiliates by the Partnership only to the extent that such
reimbursement, when added to the cost for administrative services rendered, does
not exceed 90% of the competitive rate for such services as determined above.

     (d) Any agreements, contracts and arrangements for goods or services in
addition to those authorized by Section 6.4 hereof may be entered into with a
General Partner or an Affiliate of the General Partners subject to the following
additional conditions:

          (1) any such agreements contracts or arrangements shall be embodied in
a written contract which precisely describes the subject matter thereof and all
compensation to be paid therefor;

                                      A-35
<Page>

          (2) neither a General Partner (in any capacity other than as General
Partner) nor any such Affiliate may act as paying or purchasing agent for the
Partnership and no funds of the Partnership may be paid to a General Partner or
any such Affiliate by way of reimbursement for Partnership expenses except as
permitted by this Section 12.4;

          (3) any such agreements, contracts or arrangements shall be fully and
promptly disclosed to all Partners in the reports provided for in Section
12.6(a) hereof (stating the compensation paid and to be paid by the
Partnership);

          (4) any such agreements, contracts or arrangements shall be terminable
by either party, without penalty, upon 60 days' prior written notice;

          (5) the compensation payable under any such agreements, contracts or
arrangements shall not exceed the normal and competitive rate charge for similar
goods or services by unaffiliated parties that supply such goods or perform such
services in the same geographic location;

          (6) the General Partners or any of their Affiliates performing the
services or supplying the goods which are the subject of such agreements,
contracts or arrangements must previously have been engaged in the business of
rendering such services or supplying such goods independently and as an ongoing
business;

          (7) such goods or services will be provided by the General Partners or
their Affiliates pursuant to such agreements, contracts or arrangements only in
extraordinary circumstances. For these purposes, extraordinary circumstances
would be presumed only where there is an emergency situation requiring immediate
action by the General Partners or Affiliates, and the goods are or service is
not immediately available from unaffiliated parties; and

          (8) such agreements, contracts or arrangements may be modified only by
the Consent of the holders of a majority of the Limited Partner Interests.

     (e) Subsections 12.4(a), (b) and (c) are not applicable to the fees payable
by Borrowers to Krupp Mortgage Corporation for services rendered in connection
with the origination, servicing or coinsurance of Mortgages purchased by the
Partnership subject to the limits on compensation mandated by HUD, GNMA, FNMA or
FHLMC.

     12.5 FISCAL YEAR. Except as may otherwise be determined from time to time

     (b) TAX RETURNS AND TAX INFORMATION. The General Partners shall:

          (i) have the Accountants prepare the tax returns (federal, state and

end of each calendar year in which such fiscal year was completed; and

          (ii) deliver to each Partner and Unitholder within 75 days after the
end of each calendar year the information necessary to prepare his federal
income tax return for the calendar year during which such fiscal year was
completed.

with generally accepted accounting principles and methods followed for federal
income tax purposes.

     (d) FEDERAL TAX ELECTIONS. The Partnership, in the sole discretion of the
General Partners, may make elections for federal tax purposes as follows:

the Partnership, in the absolute discretion of the General Partners, may timely
elect pursuant to Section 754 of the Code (or corresponding provisions of future

Partnership under the Code shall be made by the General Partners in such manner
as will, in the opinion of the Accountants, be most advantageous to a majority
of the Limited Partner Interests. The Partnership shall, to the extent permitted
by applicable law and regulations, elect to treat as an expense for federal
income tax purposes all amounts incurred by it for real estate taxes, interest
and other charges which may, in accordance with applicable law and regulations,
be considered as expenses.

of any adjustments to a Partner or Unitholder and the cost of any resulting
audits or adjustments of a Partner's or Unitholder's tax return will be borne
solely by the affected Partner or Unitholder.

     Section 13. MEETINGS AND VOTING RIGHTS OF LIMITED PARTNERS AND UNITHOLDERS.

     13.1 MEETINGS.

     (a) Meetings of the Limited Partners and Unitholders for any purpose may be
called by the General Partners and shall be called by the General Partners upon
receipt of a request in writing signed by the holders of 10% or more of the
Limited Partner Interests. Notice of any such meeting shall be sent within ten
days after receipt of such request. Such request shall state the purpose of the
proposed meeting and the matters proposed to be acted upon at the meeting. Such
meeting shall be held at the principal office of the Partnership, or at such
other place as may be designated by the General Partners, or, if called upon the
request of Limited Partners or Unitholders, as designated by such Limited
Partners or Unitholders. In addition, upon receipt of a request in writing
signed by the holders of 10% or more of the Limited Partner Interests, the
General Partners shall submit any matter (upon which the Limited Partners and
Unitholders are entitled to act) to the Limited Partners and Unitholders for a
vote by written Consent without a meeting.

     (b) A notice of any such meeting shall be given either personally or by
mail to each Limited Partner and Unitholder except that if such meeting shall be
called upon request of Limited Partners or Unitholders for purposes of
exercising their voting rights pursuant to Section 13.2 hereof, such notice
shall be given by certified mail. Such notice shall state the place, date and
hour of the meeting (which, if such meeting is called upon request of the
Limited Partners or Unitholders, shall not be less than 15 days nor more than 60
days after receipt of the request), and shall indicate that it is being issued
at or by the direction of the Partner or Partners calling the meeting. The
notice shall state the purpose or purposes of the meeting. If a meeting is
adjourned to another time or place, and if any announcement of the adjournment
of time or place is made at the meeting, it shall not be necessary to give
notice of the adjourned meeting. The presence in person or by proxy of a
majority in interest of the Limited Partner Interests shall constitute a quorum
at all meetings, provided, however, that if there be no such quorum, holders of
a majority in interest of such Limited Partner Interests so present or so
represented may

                                      A-39
<Page>

adjourn the meeting from time to time without further notice, until a quorum
shall have been obtained. No notice of the time, place or purpose of any meeting
need be given with respect to any Limited Partner Interest which is represented
by proxy or by a Limited Partner or Unitholder who attends in person (except
when a Limited Partner or Unitholder attends a meeting for the express purpose
of objecting at the beginning of the meeting to the transaction of any business
on the ground that the meeting is not lawfully called or convened), or with
respect to any Limited Partner Interest entitled to such notice if a waiver of
such notice, in writing, has been executed and filed with the records of the
meeting, either before or after the time thereof.

     (c) For the purpose of determining the Limited Partner Interests entitled
to vote on, or to vote at, any meeting or any adjournment thereof, the General
Partners, Limited Partners or Unitholders requesting such meeting may fix, in
advance, a date as the record date for any such determination of Interests. Such
date shall not be more than 50 days nor less than ten days before any such
meeting.

     (d) A Limited Partner or Unitholder shall be entitled to cast one vote for
each Limited Partner Interest or Unit which he owns: (i) at a meeting, in
person, by written proxy or by a signed writing directing the manner in which he
desires that his vote be cast, which writing must be received by the General
Partners (or the Limited Partners or Unitholders calling the meeting) prior to
such meeting, or (ii) without a meeting, by a signed writing directing the
manner in which he desires that his vote be cast, which writing must be received
by the General Partners (or the Limited Partners or Unitholders soliciting such
vote) prior to the date upon which the votes of Limited Partners and Unitholders
are to be counted. Any Limited Partner or Unitholder may waive notice for
attendance at any meeting and may attend by telephone or any other electronic
communication device or may execute a signed written consent. Only the votes of
Limited Partners and Unitholders of record ion a record date, if established
pursuant to clause (c) above, whether at a meeting or otherwise, shall be
counted. The laws of The Commonwealth of Massachusetts pertaining to the
validity and use of corporate proxies shall govern the validity and use of
proxies given by Limited Partners and Unitholders.

     (e) At each meeting, the Limited Partners and Unitholders present or
represented by proxy may adopt such rules for the conduct of such meeting as
they shall deem appropriate, provided that such rules shall not be inconsistent
with the provisions hereof.

     13.2 VOTING RIGHTS OF LIMITED PARTNERS AND UNITHOLDERS. Subject to Section
13.3, a majority in interest of the Limited Partner Interests, without the
concurrence of the General Partner, may (a) amend this Agreement, subject to the
provisions of Section 14 hereof and to the condition that such amendment may not
in any manner allow Limited Partners and Unitholders to take part in the control
of the Partnership's business, (b) dissolve the Partnership, (c) remove any
General Partner and elect a replacement therefor, or (d) approve or disapprove
the sale of all or substantially all the assets of the Partnership. For purposes
of exercising such rights, each Limited Partner Interest shall have one vote;
provided that the following Limited Partner Interests shall not be voted and
shall be deemed not to be outstanding for purposes of calculating applicable
percentage requirements: Limited Partner Interests held by the General Partners
or any

                                      A-40
<Page>

of their Affiliates other than the Corporate Limited Partner; and Limited
Partner Interests held by the Corporate Limited Partner other than on behalf of
Unitholders unaffiliated with the General Partners.

     13.3 CONDITIONS TO ACTION BY LIMITED PARTNERS AND UNITHOLDERS. The rights
of the Limited Partners and Unitholders pursuant to Section 13.2 hereof shall
not be effective or be exercised in any manner (i) to subject the Limited
Partners or Unitholders to liability as general partners under the Act or under
the laws of such other jurisdictions in which the Partnership is qualified or in
which a property underlying or subject to a Mortgage is located, or (ii) to
change the Partnership's status for tax purposes. Any vote and any action taken
pursuant to Section 13.2 shall be void if any Partner, within 45 days after such
action is taken, obtains a temporary restraining order, preliminary injunction
or declaratory judgment from a court of competent jurisdiction or an opinion of
counsel selected by a majority in interest of the Limited Partners and
Unitholders on grounds that such action, if given effect, would have one or more
of the prohibited effects referred to in this Section 13.3. For purposes of this
Section 13.3, counsel will be deemed to have been selected by a majority in
interest of the Limited Partners and Unitholders if such counsel is
affirmatively approved in writing by a majority in interest of the Limited
Partners and Unitholders within 45 days of the date that the holders of 10% or
more of the interests of the Limited Partners and Unitholders propose counsel
for this purpose.

     13.4 VALUATION OF INTEREST OF GENERAL PARTNERS. In the event of removal of
any General Partner pursuant to Section 13.2 hereof, its Interest as a General
Partner in the Partnership shall be appraised by two independent appraisers, one
selected by the removed or withdrawing General Partner and one by the Limited
Partners and Unitholders. In the event that such two appraisers are unable to
agree on the value of such General Partner's Interest, they shall jointly
appoint a third independent appraiser whose determination shall be final and
binding. The expense of such appraisers shall be borne equally by the removed or
withdrawing General Partner and the Partnership. The Partnership shall pay such
General Partner for the value of its Interest as so determined by delivery of a
promissory note payable in not less than 5 years in level annual installments
and bearing interest at the then base rate of Bank of New England, N.A., Boston,
Massachusetts, with interest payable annually in cash and principal payable from
any cash thereafter received by the Partnership from the sale of Partnership
Assets and prior to any distribution being made to the Partners pursuant to
Section 8.3 of this Agreement. Any amounts received pursuant to this Section
13.4 shall constitute complete and full discharge for all amounts owing to such
General Partner on account of its Interest in the Partnership. For purposes of
this Section 13.4, the independent appraiser selected by the Limited Partners
and Unitholders shall be selected in the following manner: a list of three
qualified MAI (Member of Appraisal Institute) appraisers shall be obtained (by a
General Partner not being removed or withdrawn) from the Boston chapter of the
American Institute of Real Estate Appraisers and one of said three appraisers
shall be selected by random number and proposed by such General Partner for
selection by the Limited Partners and Unitholders. Such appraiser shall be
deemed selected by the Limited Partners and Unitholders unless objected to in
writing by

                                      A-41
<Page>

a majority in interest of the Limited Partner Interests within 45 days after
notification thereof is sent in writing by such General Partner.

     Section 14. AMENDMENTS.

     (a) In addition to the right of the Limited Partners and Unitholders to
amend this Agreement pursuant to Section 13 hereof, the General Partners may
propose an amendment to this Agreement. The General Partners shall submit to all
of the Partners in writing the text of any such proposed amendment to this
Agreement and a statement by the General Partners of the purpose of any such
amendment. The General Partners may include in any submission a statement of the
view of the General Partners as to the proposed amendment. Upon the Consent of
the General Partners and of a majority in interest of the Limited Partner
Interests, such amendment shall take effect, except that no amendment adopted in
accordance with either Section 13 or 14 hereof shall increase the liability of
any Partner or Unitholder or adversely affect any Partner's or Unitholder's
share of distributions of cash or allocations of Profits or Losses for Tax
Purposes of the Partnership without in each case the approval of the Partner or
Unitholder involved, and except that any amendment of this Section 14 must be
approved by a unanimous vote with respect to all Limited Partner Interests. A
written approval may not be withdrawn or voided once it is filed with the
General Partners.

     (b) In addition to any amendments otherwise authorized herein, this
Agreement may be amended from time to time by the General Partners without the
consent of any of the Limited Partners: (i) to add to the representations,
duties or obligations of the General Partners or surrender any right or power
granted to the General Partner herein, for the benefit of the Limited Partners;
(ii) to cure any ambiguity, to correct or supplement any provision herein which
maybe inconsistent with any other pro- vision herein, or to make any other
provisions with respect to matters or questions arising under this Agreement
which will not be inconsistent with the provisions of this Agreement, (iii) to
preserve the status of the Partnership as a "partnership" for federal income tax
purposes; (iv) to delete or add any provision of this Agreement required to be
so deleted or added by the staff of the Securities and Exchange Commission or
other federal agency or by a state "Blue Sky" commissioner or similar such
official, which addition or deletion is deemed by such staff, agency or official
to be for the benefit or protection of the Limited Partners; (v) to permit the
Units to fall within any exclusion from the definition of "plan assets"
contained in Section 2550.401b-(1) of Title 29 of the Code of Federal
Regulations; or (vi) if the Partnership is advised that any allocations of
income, gain, loss, deduction, or credit provided in this Agreement are unlikely
to be respected for federal income tax purposes, to amend the allocation
provisions of this Agreement, on advice of accountants and legal counsel, to the
minimum extent necessary to effect the plan of allocations and distributions
provided in this Agreement.

     (a) APPOINTMENT. Each of the Limited Partners hereby makes, constitutes and
appoints the General Partners of the Partnership, and each person who shall
hereafter become a General Partner during the term of the Partnership and any
continuation of the

                                      A-42
<Page>

Partnership pursuant to Section 9.5 and Section II, with full power of
substitution, the true and lawful attorney-in-fact of, and in the name, place
and stead of, such Limited Partner, with the power from time to time to execute,
acknowledge, make, swear to, verify, deliver, record and/or publish:

          (i) this Agreement of Limited Partnership and the Certificate of
Limited Partnership under the laws of The Commonwealth of Massachusetts or any
other jurisdiction, that may be required by this Agreement or by the laws of
Massachusetts or any other jurisdiction, any subsequent amendment to this
Agreement and the Certificate of Limited Partnership (including, but not limited
to, amendments reflecting the addition of any signatory hereto as a Partner, or
any admission or substitution of other Partners, or reflecting the Capital
Contribution made by any signatory hereto or by any other Partner), or any other
document required from time to time to admit a Partner, to effect the
substitution of a Partner, or to effect the substitution of any Limited
Partner's assignee as a Limited Partner;

          (ii) any other document required to reflect any action of the Partners
duly taken in the manner provided for in this Agreement, whether or not such
Limited Partner voted in favor of or otherwise Consented to such action;

          (iii) any other instrument, certificate or document which may be
required by any regulatory agency, laws of the United States, any state, or any
other jurisdiction in which the Partnership is doing or intends to do business
or which the General Partners deem advisable to file or record, provided such
instrument, certificate or document is not inconsistent with the terms of this
Agreement as then in effect;

          (iv) any certificate of dissolution or cancellation of the Certificate
of Limited Partnership that may be necessary upon the termination of the
Partnership; and

          (v) any instrument or papers required to continue or terminate the
business of the Partnership pursuant to Sections 9.5 and 11 hereof;

provided that no General Partner shall take any action as attorney-in-fact for
any Limited Partner which could in any way increase the liability of such
Limited Partner beyond the liability expressly set forth in this Agreement or
alter the rights of Limited Partners under Section 8 of this Agreement, unless
(in either case) the Limited Partner has given a Power of Attorney to a General
Partner expressly for such purpose or (in the latter case) the alteration is
made pursuant to Section 14(b)(vi).

     (b) AMENDMENTS TO AGREEMENT AND CERTIFICATE.

          (i) Each of the Limited Partners is aware that the terms of this
Agreement permit certain amendments of this Agreement to be effected and certain
other actions to be taken or omitted by, or with respect to, the Partnership, in
each case with the approval of less than all the Limited Partners if a specified
percentage of the Partners shall have voted in favor of, or otherwise Consented
to, such action. If, as, and when:

                                      A-43
<Page>

               (A) an amendment of this Agreement is proposed or an action is
proposed to be taken or omitted by, or with respect to, the Partnership which
requires, under the terms of this Agreement, the Consent of a specified
percentage in interest (but less than all) of the Partners;

               (B) Partners holding the percentage of interests specified in
this Agreement as being required for such amendment or action have Consented to
such amendment or action in the manner contemplated by this Agreement; and

               (C) a Limited Partner has failed or refused to Consent to such
amendment or action (hereinafter referred to as a "non-consenting Limited
Partner"), then each non-consenting Limited Partner agrees that each
attorney-in-fact specified in Section 15(a) above, with full power of
substitution, is hereby authorized and empowered to execute, acknowledge, make,
swear to, verify, deliver, record, file and/or publish, for and on behalf of
such non-consenting Limited Partner, and in his name, place and stead, any and
all instruments and documents which may be necessary or appropriate to permit
such amendment to be lawfully made or action lawfully taken or omitted. Each
consenting and non-consenting Limited Partner is fully aware that he and each
other Limited Partner have executed this special power of attorney and that each
Limited Partner will rely on the effectiveness of such powers with a view to the
orderly administration of the Partnership's affairs.

          (ii) Any amendment to this Agreement (and to the Certificate of
Limited Partnership) substituting a Limited Partner, or adding a Limited or
General Partner, may be signed by any General Partner and by the Person to be
substituted as a Limited Partner, or added as a Limited or General Partner. Any
amendment reflecting the determination of the remaining General Partner or
Partners to continue the business of the Partnership upon the Withdrawal of a
General Partner need be signed only by one General Partner. The execution of any
such amendment on behalf of a Limited Partner or any proposed substitute or
added Limited Partner may be effected by his attorney-in-fact.

     (c) POWER COUPLED WITH AN INTEREST. The foregoing grant of authority:

          (i) is a special power of attorney coupled with an interest in favor
of the General Partners and as such shall be irrevocable and shall survive the
death or insanity of each Limited Partner;

          (ii) may be exercised for each Limited Partner by a signature of any
General Partner of the Partnership or by listing the names of all of the Limited
Partners, including such Limited Partner, and executing any instrument with a
single signature of any General Partner acting as attorney-in-fact for all of
them; and

          (iii) shall survive the Assignment by any Limited Partner of the whole
or any portion of his Interest (including the assignment by the Corporate
Limited Partner to the Unitholders under Section 7.6 hereof), except that, where
the assignee of the whole thereof has furnished a power of attorney and has been
approved by the General Partners for admission to the Partnership as a
Substitute Limited Partner, this power of attorney

                                      A-44
<Page>

shall survive such Assignment with respect to the assignor for the sole purpose
of enabling a General Partner to execute, acknowledge and file any instrument
necessary to effect such substitution and shall thereafter terminate with
respect to any Partner who assigns his entire Interest.

     (d) POWER OF ATTORNEY BY SUBSTITUTE INVESTOR LIMITED PARTNERS. A similar
power of attorney shall be one of the instruments which the General Partners
shall require an assignee of a Limited Partner to execute as a condition to the
admission of such assignee as a Substitute Limited Partner.
