                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                Year ended December 31, 1999 compared to the year
          ended December 31, 1998 and the year ended December 31, 1998
                  compared to the year ended December 31, 1997

   Certain statements in this annual report of American Income Fund I-B, a
Massachusetts Limited Partnership (the "Partnership") that are not historical
fact constitute "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995 and are subject to a variety of risks
and uncertainties. There are a number of factors that could cause actual results
to differ materially from those expressed in any forward-looking statements made
herein. These factors include, but are not limited to, the outcome of the Class
Action Lawsuit described in Note 6 to the accompanying financial statements and
the remarketing of the Partnership's equipment.

Overview

   The Partnership was organized in 1990 as a direct-participation equipment
leasing program to acquire a diversified portfolio of capital equipment subject
to lease agreements with third parties. Presently, the Partnership is a Nominal
Defendant in a Class Action Lawsuit, the outcome of which could significantly
alter the nature of the Partnership's organization and its future business
operations. See Note 6 to the accompanying financial statements. Pursuant to the
Amended and Restated Agreement and Certificate of Limited Partnership (the
"Restated Agreement, as amended"), the Partnership is scheduled to be dissolved
by December 31, 2001.

Year 2000 Issue

   The Partnership uses information systems provided by Equis Financial Group
Limited Partnership ("EFG") and has no information systems of its own. EFG
completed all Year 2000 readiness work prior to December 31, 1999 and did not
experience any significant problems. Additionally, EFG is not aware of any
outside customer or vendor that experienced a Year 2000 issue that would have a
material effect on the Partnership's results of operations, liquidity, or
financial position. However, EFG has no means of ensuring that all customers,
vendors and third-party servicers have conformed to Year 2000 standards. The
effect of this risk to the Partnership is not determinable.

Results of Operations

   For the year ended December 31, 1999, the Partnership recognized lease
revenue of $303,817, compared to $352,921 and $658,262 for the years ended
December 31, 1998 and 1997, respectively. The decrease in lease revenue from
1997 to 1999 resulted principally from the sale of the Partnership's interest in
two aircraft which provided a total of $44,050 and $278,208 of lease revenue for
the years ended December 31, 1998 and 1997, respectively. Other reductions in
lease revenue from 1997 to 1999 resulted from lease term expirations and the
sale of other equipment. In the future, lease revenue will continue to decline
due to lease term expirations and equipment sales. The Partnership also earns
interest income from temporary investments of rental receipts and equipment
sales proceeds in short-term instruments.

   The Partnership's equipment portfolio includes certain assets in which the
Partnership holds a proportionate ownership interest. In such cases, the
remaining interests are owned by an affiliated equipment leasing program
sponsored by EFG. Proportionate equipment ownership enabled the Partnership to
further diversify its equipment portfolio at inception by participating in the
ownership of selected assets, thereby reducing the general levels of risk which
could have resulted from a concentration in any single equipment type, industry
or lessee. The Partnership and each affiliate individually report, in proportion
to their respective ownership interests, their respective shares of assets,
liabilities, revenues, and expenses associated with the equipment.

   In 1999, the Partnership sold equipment having a net book value of $35,179 to
existing lessees and third parties. These sales resulted in a net gain, for
financial statement purposes, of $38,412 compared to a net gain in 1998 of
$6,520 on equipment having a net book value of $671,684 and a net gain in 1997
of $115,379 on equipment having a net book value of $8,564.


                                       3


   It cannot be determined whether future sales of equipment will result in a
net gain or a net loss to the Partnership, as such transactions will be
dependent upon the condition and type of equipment being sold and its
marketability at the time of sale. In addition, the amount of gain or loss
reported for financial statement purposes is partly a function of the amount of
accumulated depreciation associated with the equipment being sold.

   The ultimate realization of residual value for any type of equipment is
dependent upon many factors, including EFG's ability to sell and re-lease
equipment. Changing market conditions, industry trends, technological advances,
and many other events can converge to enhance or detract from asset values at
any given time. EFG attempts to monitor these changes in order to identify
opportunities which may be advantageous to the Partnership and which will
maximize total cash returns for each asset.

   The total economic value realized for each asset is comprised of all primary
lease term revenues generated from that asset, together with its residual value.
The latter consists of cash proceeds realized upon the asset's sale in addition
to all other cash receipts obtained from renting the asset on a re-lease,
renewal or month-to-month basis. The Partnership classifies such residual rental
payments as lease revenue. Consequently, the amount of gain or loss reported in
the financial statements is not necessarily indicative of the total residual
value the Partnership achieved from leasing the equipment.

   Depreciation expense was $99,072, $213,530 and $431,940 for the years ended
December 31, 1999, 1998 and 1997, respectively. For financial reporting
purposes, to the extent that an asset is held on primary lease term, the
Partnership depreciates the difference between (i) the cost of the asset and
(ii) the estimated residual value of the asset on a straight-line basis over
such term. For purposes of this policy, estimated residual values represent
estimates of equipment values at the date of primary lease expiration. To the
extent that an asset is held beyond its primary lease term, the Partnership
continues to depreciate the remaining net book value of the asset on a
straight-line basis over the asset's remaining economic life.

   Interest expense $39,438 or 6% of lease revenue in 1997. The Partnership's
notes payable were fully amortized at January 1, 1998.

   Management fees were approximately 3.5%, 3.8%, and 4.4% of lease revenue
during the years ended December 31, 1999, 1998 and 1997, respectively.
Management fees are based on 5% of gross lease revenue generated by operating
leases and 2% of gross lease revenue generated by full payout leases.

   Operating expenses were $232,350, $450,680, and $114,704 for the years ended
December 31, 1999, 1998 and 1997, respectively. Operating expenses in 1999
include approximately $50,000 accrued for certain legal and Consolidation
expenses related to the Class Action Lawsuit described in Note 6 to the
financial statements. During the year ended December 31, 1998, the Partnership
incurred or accrued approximately $262,000 for such expenses related to the
Class Action Lawsuit. In addition, the Partnership incurred certain remarketing
expenses in 1998 related to the sale of its interest in an aircraft. Other
operating expenses consist principally of professional service costs, such as
audit and other legal fees, as well as printing, distribution and remarketing
expenses. In certain cases, equipment storage or repairs and maintenance costs
may be incurred in connection with equipment being remarketed.

Liquidity and Capital Resources and Discussion of Cash Flows

   In connection with a preliminary settlement agreement for the Class Action
Lawsuit described in Note 6 to the accompanying financial statements, the
Partnership is permitted to invest in new equipment or other business
activities, subject to certain limitations. On March 8, 2000, the Partnership
invested $1,310,000 in a debt instrument that matures in September 2002. (See
Notes 6 and 7 to the accompanying financial statements for additional
information concerning this transaction.)

   The Partnership by its nature is a limited life entity. As an equipment
leasing program, the Partnership's principal operating activities derive from
asset rental transactions. Accordingly, the Partnership's principal source of
cash from operations is provided by the collection of periodic rents. These cash
inflows are used to pay management fees and operating costs. In addition, prior
to 1999, such cash inflows were used to satisfy debt service obligations
associated with leveraged leases. Operating activities generated net cash
inflows of $180,054,


                                       4


$187,610 and $460,812 in 1999, 1998 and 1997, respectively. Future renewal,
re-lease and equipment sale activities will cause a decline in the Partnership's
lease revenues and corresponding sources of operating cash. The amount of future
interest income is expected to fluctuate as a result of changing interest rates
and the level of cash available for investment, among other factors. Overall,
expenses associated with rental activities, such as management fees, and net
cash flow from operating activities also will decline as the Partnership
experiences a higher frequency of remarketing events.

   Cash expended for equipment acquisitions and cash realized from equipment
disposal transactions are reported under investing activities on the
accompanying Statement of Cash Flows. During 1997, the Partnership expended
$75,957 to upgrade certain research and test equipment. There were no equipment
acquisitions during 1999 or 1998. For the year ended December 31, 1999, the
Partnership realized $73,591 in equipment sale proceeds compared to $678,204 and
$123,943 in 1998 and 1997, respectively. Future inflows of cash from asset
disposals will vary in timing and amount and will be influenced by many factors
including, but not limited to, the frequency and timing of lease expirations,
the type of equipment being sold, its condition and age, and future market
conditions.

   At December 31, 1999, the Partnership was due aggregate future minimum lease
payments of $210,235 from contractual lease agreements (see Note 2 to the
financial statements). At the expiration of the individual primary and renewal
lease terms underlying the Partnership's future minimum lease payments, the
Partnership will sell the equipment or enter re-lease or renewal agreements when
considered advantageous by the General Partner and EFG. Such future remarketing
activities will result in the realization of additional cash inflows in the form
of equipment sale proceeds or rents from renewals and re-leases, the timing and
extent of which cannot be predicted with certainty. This is because the timing
and extent of remarketing events often is dependent upon the needs and interests
of the existing lessees. Some lessees may choose to renew their lease contracts,
while others may elect to return the equipment. In the latter instances, the
equipment could be re-leased to another lessee or sold to a third party.

   The Partnership obtained long-term financing in connection with certain
equipment leases. The repayments of principal related to such indebtedness are
reported as a component of financing activities. The Partnership's indebtedness
was fully amortized on January 1, 1998.

   There are no formal restrictions under the Restated Agreement, as amended,
that materially limit the Partnership's ability to pay cash distributions,
except that the General Partner may suspend or limit cash distributions to
ensure that the Partnership maintains sufficient working capital reserves to
cover, among other things, operating costs and potential expenditures, such as
refurbishment costs to remarket equipment upon lease expiration. Liquidity is
especially important as the Partnership matures and sells equipment, because the
remaining equipment base consists of fewer revenue-producing assets that are
available to cover prospective cash disbursements. Insufficient liquidity could
inhibit the Partnership's ability to sustain its operations or maximize the
realization of proceeds from remarketing its remaining assets.

   Cash distributions to the General and Limited Partners have been declared and
generally paid within fifteen days following the end of each calendar quarter.
The payment of such distributions is reported under financing activities on the
accompanying Statement of Cash Flows. For the year ended December 31, 1999, the
Partnership declared total cash distributions of Distributable Cash From
Operations and Distributable Cash From Sales and Refinancings of $226,351. In
accordance with the Restated Agreement, as amended, the Limited Partners were
allocated 95% of these distributions, or $215,033 and the General Partner was
allocated 5%, or $11,318. The fourth quarter 1999 cash distribution was paid on
January 14, 2000.

   Cash distributions paid to the Limited Partners consist of both a return of
and a return on capital. Cash distributions do not represent and are not
indicative of yield on investment. Actual yield on investment cannot be
determined with any certainty until conclusion of the Partnership and will be
dependent upon the collection of all future contracted rents, the generation of
renewal and/or re-lease rents, and the residual value realized for each asset at
its disposal date.

   The Partnership's capital account balances for federal income tax and for
financial reporting purposes are different primarily due to differing treatments
of income and expense items for income tax purposes in comparison to financial
reporting purposes (generally referred to as permanent or timing differences;
see Note 5 to the


                                       5


financial statements presented in the Partnership's 1999 Annual Report). For
instance, selling commissions and organization and offering costs pertaining to
syndication of the Partnership's limited partnership units are not deductible
for federal income tax purposes, but are recorded as a reduction of partners'
capital for financial reporting purposes. Therefore, such differences are
permanent differences between capital accounts for financial reporting and
federal income tax purposes. Other differences between the bases of capital
accounts for federal income tax and financial reporting purposes occur due to
timing differences. Such items consist of the cumulative difference between
income or loss for tax purposes and financial statement income or loss and the
difference between distributions (declared vs. paid) for income tax and
financial reporting purposes. The principal component of the cumulative
difference between financial statement income or loss and tax income or loss
results from different depreciation policies for book and tax purposes.

   For financial reporting purposes, the General Partner has accumulated a
capital deficit at December 31, 1999. This is the result of aggregate cash
distributions to the General Partner being in excess of its capital contribution
of $1,000 and its allocation of financial statement net income or loss.
Ultimately, the existence of a capital deficit for the General Partner for
financial reporting purposes is not indicative of any further capital
obligations to the Partnership by the General Partner. The Restated Agreement,
as amended, requires that upon the dissolution of the Partnership, the General
Partner will be required to contribute to the Partnership an amount equal to any
negative balance which may exist in the General Partner's tax capital account.
At December 31, 1999, the General Partner had a positive tax capital account
balance.

   The outcome of the Class Action Lawsuit described in Note 6 to the
accompanying financial statements will be the principal factor in determining
the future of the Partnership's operations. The proposed settlement to that
lawsuit, if effected, will materially change the future organizational structure
and business interests of the Partnership, as well as its cash distribution
policies. In addition, commencing with the first quarter of 2000, the General
Partner believes that it will be in the Partnership's best interests to suspend
the payment of quarterly cash distributions pending final resolution of the
Class Action Lawsuit. Accordingly, future cash distributions are not expected to
be paid until the Class Action Lawsuit is adjudicated.

                         REPORT OF INDEPENDENT AUDITORS


To the Partners of American Income Fund I-B,
a Massachusetts Limited Partnership:

   We have audited the accompanying statements of financial position of American
Income Fund I-B, a Massachusetts Limited Partnership, as of December 31, 1999
and 1998, and the related statements of operations, changes in partners'
capital, and cash flows for each of the three years in the period ended December
31, 1999. These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of American Income Fund I-B, a
Massachusetts Limited Partnership at December 31, 1999 and 1998, and the results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1999, in conformity with accounting principles generally
accepted in the United States.

   Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The Additional Financial Information
identified in the Index to Annual Report to the Partners is presented for
purposes of additional analysis and is not a required part of the basic
financial statements. Such information has been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                        Notes to the Financial Statements

                                December 31, 1999

NOTE 1 - ORGANIZATION AND PARTNERSHIP MATTERS

   American Income Fund I-B, a Massachusetts Limited Partnership (the
"Partnership") was organized as a limited partnership under the Massachusetts
Uniform Limited Partnership Act (the "Uniform Act") on December 31, 1990, for
the purpose of acquiring and leasing to third parties a diversified portfolio of
capital equipment. Partners' capital initially consisted of contributions of
$1,000 from the General Partner (AFG Leasing VI Incorporated) and $100 from the
Initial Limited Partner (AFG Assignor Corporation). On March 1, 1991, the
Partnership issued 286,711 units of limited partnership interest (the "Units")
to 453 investors. The Partnership's General Partner, AFG Leasing VI
Incorporated, is a Massachusetts corporation formed in 1990 and an affiliate of
Equis Financial Group Limited Partnership (formerly known as American Finance
Group), a Massachusetts limited partnership ("EFG"). The General Partner is not
required to make any other capital contributions except as may be required under
the Uniform Act and Section 6.1(b) of the Amended and Restated Agreement and
Certificate of Limited Partnership ("Restated Agreement, as amended").

   Significant operations commenced March 1, 1991 when the Partnership made its
initial equipment purchase. Pursuant to the Restated Agreement, as amended,
Distributable Cash From Operations and Distributable Cash From Sales or
Refinancings will be allocated 95% to the Limited Partners and 5% to the General
Partner.

   Under the terms of a Management Agreement between the Partnership and EFG,
management services are provided by EFG to the Partnership at fees which the
General Partner believes to be competitive for similar services (see Note 4).

   EFG is a Massachusetts limited partnership formerly known as American Finance
Group ("AFG"). AFG was established in 1988 as a Massachusetts general
partnership and succeeded American Finance Group, Inc., a Massachusetts
corporation organized in 1980. EFG and its subsidiaries (collectively, the
"Company") are engaged in various aspects of the equipment leasing business,
including EFG's role as Manager or Advisor to the Partnership and several other
direct-participation equipment leasing programs sponsored or co-sponsored by EFG
(the "Other Investment Programs"). The Company arranges to broker or originate
equipment leases, acts as remarketing agent and asset manager, and provides
leasing support services, such as billing, collecting, and asset tracking.

   The general partner of EFG, with a 1% controlling interest, is Equis
Corporation, a Massachusetts corporation owned and controlled entirely by Gary
D. Engle, its President, Chief Executive Officer and sole Director. Equis
Corporation also owns a controlling 1% general partner interest in EFG's 99%
limited partner, GDE Acquisition Limited Partnership ("GDE LP"). Equis
Corporation and GDE LP were established in December 1994 by Mr. Engle for the
sole purpose of acquiring the business of AFG.

   In January 1996, the Company sold certain assets of AFG relating primarily to
the business of originating new leases, and the name "American Finance Group",
and its acronym, to a third-party. AFG changed its name to Equis Financial Group
Limited Partnership after the sale was concluded. Pursuant to terms of the sale
agreements, EFG specifically reserved the rights to continue using the name
American Finance Group and its acronym in connection with the Partnership and
the Other Investment Programs and to continue managing all assets owned by the
Partnership and the Other Investment Programs.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Statement of Cash Flows

   The Partnership considers liquid investment instruments purchased with a
maturity of three months or less to be cash equivalents. From time to time, the
Partnership invests excess cash with large institutional banks in federal agency
discount notes and repurchase agreements with overnight maturities. Under the
terms of the agreements, title to the underlying securities passes to the
Partnership. The securities underlying the agreements are book entry securities.
At December 31, 1999, the Partnership had $1,971,769 invested in federal agency
discount notes, repurchase agreements secured by U.S. Treasury Bills or
interests in U.S. Government securities, or other highly liquid overnight
investments.

Revenue Recognition

   Rents are payable to the Partnership monthly or quarterly and no significant
amounts are calculated on factors other than the passage of time. The leases are
accounted for as operating leases and are noncancellable. Rents received prior
to their due dates are deferred. In certain instances, the Partnership may enter
renewal or re-lease agreements which expire beyond the Partnership's anticipated
dissolution date. This circumstance is not expected to prevent the orderly
wind-up of the Partnership's business activities as the General Partner and EFG
would seek to sell the then-remaining equipment assets either to the lessee or
to a third party, taking into consideration the amount of future noncancellable
rental payments associated with the attendant lease agreements. See also Note 6
regarding the Class Action Lawsuit. Future minimum rents of $210,235 are due as
follows:

   For the year ending December 31, 2000           $ 114,506

Use of Estimates

   The preparation of the financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

                            AMERICAN INCOME FUND I-B,
                       a Massachusetts Limited Partnership
                        Notes to the Financial Statements

                                   (Continued)

Equipment on Lease

   All equipment was acquired from EFG, one of its Affiliates or from
third-party sellers. Equipment Cost means the actual cost paid by the
Partnership to acquire the equipment, including acquisition fees. Where
equipment was acquired from EFG or an Affiliate, Equipment Cost reflects the
actual price paid for the equipment by EFG or the Affiliate plus all actual
costs incurred by EFG or the Affiliate while carrying the equipment, including
all liens and encumbrances, less the amount of all primary term rents earned by
EFG or the Affiliate prior to selling the equipment. Where the seller of the
equipment was a third party, Equipment Cost reflects the seller's invoice price.

Depreciation

   The Partnership's depreciation policy is intended to allocate the cost of
equipment over the period during which it produces economic benefit. The
principal period of economic benefit is considered to correspond to each asset's
primary lease term, which term generally represents the period of greatest
revenue potential for each asset. Accordingly, to the extent that an asset is
held on primary lease term, the Partnership depreciates the difference between
(i) the cost of the asset and (ii) the estimated residual value of the asset on
a straight-line basis over such term. For purposes of this policy, estimated
residual values represent estimates of equipment values at the date of primary
lease expiration. To the extent that an asset is held beyond its primary lease
term, the Partnership continues to depreciate the remaining net book value of
the asset on a straight-line basis over the asset's remaining economic life.
Periodically, the General Partner evaluates the net carrying value of equipment
to determine whether it exceeds estimated net realizable value. Adjustments to
reduce the net carrying value of equipment are recorded in those instances where
estimated net realizable value is considered to be less than net carrying value.

   The ultimate realization of residual value for any type of equipment is
dependent upon many factors, including EFG's ability to sell and re-lease
equipment. Changing market conditions, industry trends, technological advances,
and many other events can converge to enhance or detract from asset values at
any given time.

Accrued Liabilities - Affiliate

   Unpaid operating expenses and fees paid by EFG on behalf of the Partnership
and accrued but unpaid administrative charges and management fees are reported
as Accrued Liabilities - Affiliate (see Note 4).

Contingencies

   It is the Partnership's policy to recognize a liability for goods and
services during the period when the goods or services are received. To the
extent that the Partnership has a contingent liability, meaning generally a
liability the payment of which is subject to the outcome of a future event, the
Partnership recognizes a liability in accordance with Statement of Financial
Accounting Standards No. 5 "Accounting for Contingencies" ("SFAS No. 5"). SFAS
No. 5 requires the recognition of contingent liabilities when the amount of
liability can be reasonably estimated and the liability is likely to be
incurred.

   The Partnership is a Nominal Defendant in a Class Action Lawsuit. In 1998, a
settlement proposal to resolve that litigation was negotiated and remains
pending (See Note 7). The Partnership's estimated exposure for costs anticipated
to be incurred in pursuing the settlement proposal is approximately $312,000
consisting principally of legal fees and other professional service costs. These
costs are expected to be incurred regardless of whether the proposed settlement
ultimately is effected and, therefore, the Partnership accrued approximately
$262,000 of these costs in 1998 following the Court's approval of the settlement
plan. The cost estimate is subject to change and is monitored by the General
Partner based upon the progress of the settlement proposal and other pertinent
information. As a result, the Partnership accrued and expensed an additional
$50,000 for such costs during 1999.

                                   (Continued)

Allocation of Profits and Losses

   For financial statement purposes, net income or loss is allocated to each
Partner according to their respective ownership percentages (95% to the Limited
Partners and 5% to the General Partner). See Note 5 for allocation of income or
loss for income tax purposes.

Net Income (Loss) and Cash Distributions Per Unit

   Net income (loss) and cash distributions per Unit are based on 286,711 Units
outstanding during each of the three years in the period ended December 31, 1999
and computed after allocation of the General Partner's 5% share of net income
(loss) and cash distributions.

Provision for Income Taxes

   No provision or benefit from income taxes is included in the accompanying
financial statements. The Partners are responsible for reporting their
proportionate shares of the Partnership's taxable income or loss and other tax
attributes on their tax returns.

NOTE 3 - EQUIPMENT

   The following is a summary of equipment owned by the Partnership at December
31, 1999. Remaining Lease Term (Months), as used below, represents the number of
months remaining from December 31, 1999 under contracted lease terms and is
presented as a range when more than one lease agreement is contained in the
stated equipment category. A Remaining Lease Term equal to zero reflects
equipment either held for sale or re-lease or being leased on a month-to-month
basis. In the opinion of EFG, the acquisition cost of the equipment did not
exceed its fair market value.

   In certain cases, the cost of the Partnership's equipment represents a
proportionate ownership interest. The remaining interests are owned by EFG or an
affiliated equipment leasing program sponsored by EFG. The Partnership and each
affiliate individually report, in proportion to their respective ownership
interests their respective shares of assets, liabilities, revenues, and expenses
associated with the equipment. Proportionate equipment ownership enabled the
Partnership to further diversify its equipment portfolio at inception by
participating in the ownership of selected assets, thereby reducing the general
levels of risk which could have resulted from a concentration in any single
equipment type, industry or lessee. At December 31, 1999, the

                        Notes to the Financial Statements

                                   (Continued)

Partnership's equipment portfolio included equipment having a proportionate
original cost of $151,529, representing approximately 13% of total equipment
cost.

   Generally, the costs associated with maintaining, insuring and operating the
Partnership's equipment are incurred by the respective lessees pursuant to terms
specified in their individual lease agreements with the Partnership.

   As equipment is sold to third parties, or otherwise disposed of, the
Partnership recognizes a gain or loss equal to the difference between the net
book value of the equipment at the time of sale or disposition and the proceeds
realized upon sale or disposition. The ultimate realization of estimated
residual value in the equipment is dependent upon, among other things, EFG's
ability to maximize proceeds from selling or re-leasing the equipment upon the
expiration of the primary lease terms. At December 31, 1999, the Partnership was
not holding any equipment not subject to a lease and no equipment was held for
sale or re-lease.

NOTE 4 - RELATED PARTY TRANSACTIONS

   All operating expenses incurred by the Partnership are paid by EFG on behalf
of the Partnership and EFG is reimbursed at its actual cost for such
expenditures. Fees and other costs incurred during the years ended December 31,
1999, 1998 and 1997, which were paid or accrued by the Partnership to EFG or its
Affiliates, are as follows:

   As provided under the terms of the Management Agreement, EFG is compensated
for its services to the Partnership. Such services include acquisition and
management of equipment. For acquisition services, EFG was compensated by an
amount equal to 2.23% of Equipment Base Price paid by the Partnership. For
management services, EFG is compensated by an amount equal to 5% of gross
operating lease rental revenues and 2% of gross full payout lease rental
revenues received by the Partnership. Both acquisition and management fees are
subject to certain limitations defined in the Management Agreement.

   Administrative charges represent amounts owed to EFG, pursuant to Section
9.4(c) of the Restated Agreement, as amended, for persons employed by EFG who
are engaged in providing administrative services to the Partnership.
Reimbursable operating expenses due to third parties represent costs paid by EFG
on behalf of the Partnership which are reimbursed to EFG at actual cost.

   All equipment was purchased from EFG, one of its affiliates, including other
equipment leasing programs sponsored by EFG, or from third-party sellers. The
Partnership's Purchase Price is determined by the method described in Note 2,
Equipment on Lease.

   All rents and proceeds from the sale of equipment are paid directly to EFG.
EFG temporarily deposits collected funds in a separate interest-bearing escrow
account prior to remittance to the Partnership. At December

NOTE 5 - INCOME TAXES

   The Partnership is not a taxable entity for federal income tax purposes.
Accordingly, no provision for income taxes has been recorded in the accounts of
the Partnership.

   For financial statement purposes, the Partnership allocates net income or
loss to each class of partner according to their respective ownership
percentages (95% to the Limited Partners and 5% to the General Partner). This
convention differs from the income or loss allocation requirements for income
tax and Dissolution Event purposes as delineated in the Restated Agreement, as
amended. For income tax purposes, the Partnership allocates net income or net
loss in accordance with the provisions of such agreement. The Restated
Agreement, as amended, requires that upon dissolution of the Partnership, the
General Partner will be required to contribute to the Partnership an amount
equal to any negative balance which may exist in the General Partner's tax
capital account. At December 31, 1999, the General Partner had a positive tax
capital account balance.

   The following is a reconciliation between net income or loss reported for
financial statement and federal income tax reporting purposes for the years
ended December 31, 1999, 1998 and 1997:

NOTE 6 - LEGAL PROCEEDINGS

   In January 1998, certain plaintiffs (the "Plaintiffs") filed a class and
derivative action, captioned Leonard Rosenblum, et al. v. Equis Financial Group
Limited Partnership, et al., in the United States District Court for the
Southern District of Florida (the "Court") on behalf of a proposed class of
investors in 28 equipment leasing programs sponsored by EFG, including the
Partnership (collectively, the "Nominal Defendants"), against EFG and a number
of its affiliates, including the General Partner, as defendants (collectively,
the "Defendants"). Certain of the Plaintiffs, on or about June 24, 1997, had
filed an earlier derivative action, captioned Leonard Rosenblum, et al. v. Equis
Financial Group Limited Partnership, et al., in the Superior Court of the
Commonwealth of Massachusetts on behalf of the Nominal Defendants against the
Defendants. Both actions are referred to herein collectively as the "Class
Action Lawsuit".

   The Plaintiffs have asserted, among other things, claims against the
Defendants on behalf of the Nominal Defendants for violations of the Securities
Exchange Act of 1934, common law fraud, breach of contract, breach of fiduciary
duty, and violations of the partnership or trust agreements that govern each of
the Nominal Defendants. The Defendants have denied, and continue to deny, that
any of them have committed or threatened to commit any violations of law or
breached any fiduciary duties to the Plaintiffs or the Nominal Defendants.

   On July 16, 1998, counsel for the Defendants and the Plaintiffs executed a
Stipulation of Settlement setting forth terms pursuant to which a settlement of
the Class Action Lawsuit is intended to be achieved and which, among other
things, is expected to reduce the burdens and expenses attendant to continuing
litigation. The Stipulation of Settlement was preliminarily approved by the
Court on August 20, 1998 when the Court issued its "Order Preliminarily
Approving Settlement, Conditionally Certifying Settlement Class and Providing
for Notice of, and Hearing on, the Proposed Settlement" (the "August 20 Order").

   On March 12, 1999, counsel for the Plaintiffs and the Defendants entered into
an amended stipulation of settlement (the "Amended Stipulation") which was filed
with the Court on March 12, 1999. The Amended Stipulation was preliminarily
approved by the Court by its "Modified Order Preliminarily Approving Settlement,
Conditionally Certifying Settlement Class and Providing For Notice of, and
Hearing On, the Proposed Settlement"

                       a Massachusetts Limited Partnership
                        Notes to the Financial Statements

                                   (Continued)

dated March 22, 1999 (the "March 22 Order"). The Amended Stipulation, among
other things, divided the Class Action Lawsuit into two separate sub-classes
that could be settled individually. On May 26, 1999, the Court issued an Order
and Final Judgment approving settlement of one of the sub-classes. Settlement of
the second sub-class, involving the Partnership and 10 affiliated partnerships
(collectively referred to as the "Exchange Partnerships"), remains pending due,
in part, to the complexity of the proposed settlement pertaining to this class.

   In February 2000, counsel for the Plaintiffs and the Defendants entered into
a second amended stipulation of settlement (the "Second Amended Stipulation")
which modified certain of the settlement terms contained in the Amended
Stipulation. The Second Amended Stipulation was preliminarily approved by the
Court by its "Second Modified Order Preliminarily Approving Settlement,
Conditionally Certifying Settlement Class and Providing For Notice of, and
Hearing On, the Proposed Settlement" dated March 6, 2000 (the "March 2000
Order"). Prior to issuing a final order approving the settlement of the second
sub-class involving the Partnership, the Court will hold a fairness hearing that
will be open to all interested parties and permit any party to object to the
settlement. The investors of the Partnership and all other plaintiff sub-class
members will receive a Notice of Settlement and other information pertinent to
the settlement of their claims that will be mailed to them in advance of the
fairness hearing.

   The settlement of the second sub-class is premised on the consolidation of
the Exchange Partnerships' net assets (the "Consolidation"), subject to certain
conditions, into a single successor company ("Newco"). Under the proposed
Consolidation, the partners of the Exchange Partnerships would receive both
common stock in Newco and a cash distribution; and thereupon the Exchange
Partnerships would be dissolved. In addition, EFG would contribute certain
management contracts, operations personnel, and business opportunities to Newco
and cancel its current management contracts with all of the Exchange
Partnerships. Newco would operate principally as a finance company and would use
its best efforts to list its shares on the NASDAQ National Market or another
national exchange or market as soon after the Consolidation as Newco deems that
market conditions and its business operations are suitable for listing its
shares and Newco has satisfied all necessary regulatory and listing
requirements. The potential benefits and risks of the Consolidation will be
presented in a Solicitation Statement that will be mailed to all of the partners
of the Exchange Partnerships as soon as the associated regulatory review process
is completed and at least 60 days prior to the fairness hearing. A preliminary
Solicitation Statement was filed with the Securities and Exchange Commission on
August 24, 1998 and remains pending. Class members will be notified of the
actual fairness hearing date when it is confirmed.

   One of the principal objectives of the Consolidation is to create a company
that would have the potential to generate more value for the benefit of existing
limited partners than other alternatives, including continuing the Partnership's
customary business operations until all of its assets are disposed in the
ordinary course of business. To facilitate the realization of this objective,
the Amended Stipulation provided, among other things, that commencing March 22,
1999, the Exchange Partnerships could collectively invest up to 40% of the total
aggregate net asset values of all of the Exchange Partnerships in any
investment, including additional equipment and other business activities that
the general partners of the Exchange Partnerships and EFG reasonably believed to
be consistent with the anticipated business interests and objectives of Newco,
subject to certain limitations. The Second Amended Stipulation, among other
things, quantified the 40% limitation using a whole dollar amount of $32 million
in the aggregate.

   On March 8, 2000, the Exchange Partnerships collectively invested $32 million
as permitted by the Second Amended Stipulation approved by the Court. The
Partnership's portion of the aggregate investment is $1,310,000. The investment
consists of a term loan to Echelon Residential Holdings LLC, a newly-formed real
estate development company that will be owned by several investors, including
James A. Coyne, Executive Vice President of EFG. Mr. Coyne, in his individual
capacity, is the only investor in Echelon Residential Holdings LLC who is
related to EFG. The loan proceeds were used by Echelon Residential Holdings LLC
in the formation of a subsidiary, Echelon Residential LLC, that in turn acquired
various real estate assets from Echelon International Corporation, a Florida
based real estate company. The loan has a term of 30 months maturing on
September 7,

2002 and bears interest at the annual rate of 14% for the first 24 months and
18% for the final six months of the term. Interest accrues and compounds
monthly but is not payable until maturity. Echelon Residential Holdings LLC
has pledged a security interest in all of its right, title and interest in
and to its membership interests in Echelon Residential LLC to the Exchange
Partnerships as collateral.

   In the absence of the Court's authorization to enter into new investment
activities, the Partnership's Restated Agreement, as amended, would not permit
such activities without the approval of limited partners owning a majority of
the Partnership's outstanding Units. Consistent with the Amended Stipulation,
the Second Amended Stipulation provides terms for unwinding any new investment
transactions in the event that the Consolidation is not effected or the
Partnership objects to its participation in the Consolidation.

   The Second Amended Stipulation, as well as the Amended Stipulation and the
original Stipulation of Settlement, prescribe certain conditions necessary to
effect a final settlement, including providing the partners of the Exchange
Partnerships with the opportunity to object to the participation of their
partnership in the Consolidation. Assuming the proposed settlement is effected
according to present terms, the Partnership's share of legal fees and expenses
related to the Class Action Lawsuit and the Consolidation is estimated to be
approximately $312,000, of which approximately $262,000 was accrued and expensed
by the Partnership in 1998 and approximately $50,000 was accrued and expensed in
1999.

   While the Court's August 20 Order enjoined certain class members, including
all of the partners of the Partnership, from transferring, selling, assigning,
giving, pledging, hypothecating, or otherwise disposing of any Units pending the
Court's final determination of whether the settlement should be approved, the
March 22 Order permitted the partners to transfer Units to family members or as
a result of the divorce, disability or death of the partner. No other transfers
are permitted pending the Court's final determination of whether the settlement
should be approved. The provision of the August 20 Order which enjoined the
General Partners of the Exchange Partnerships from, among other things,
recording any transfers not in accordance with the Court's order remains
effective.

   There can be no assurance that settlement of the sub-class involving the
Exchange Partnerships will receive final Court approval and be effected. There
also can be no assurance that all or any of the Exchange Partnerships will
participate in the Consolidation because if limited partners owning more than
one-third of the outstanding Units of a partnership object to the Consolidation,
then that partnership will be excluded from the Consolidation. Notwithstanding
the extent of delays experienced thus far in achieving a final settlement of the
Class Action Lawsuit with respect to the Exchange Partnerships, the General
Partner and its affiliates, in consultation with counsel, continue to feel that
there is a reasonable basis to believe that a final settlement of the sub-class
involving the Exchange Partnerships ultimately will be achieved. However, in the
absence of a final settlement approved by the Court, the Defendants intend to
defend vigorously against the claims asserted in the Class Action Lawsuit.
Neither the General Partner nor its affiliates can predict with any degree of
certainty the cost of continuing litigation to the Partnership or the ultimate
outcome.

   In addition to the foregoing, the Partnership is a party to other lawsuits
that have arisen out of the conduct of its business, principally involving
disputes or disagreements with lessees over lease terms and conditions as
described below:

Action involving National Steel Corporation

   EFG, on behalf of the Partnership and certain affiliated investment programs
(collectively, the "Plaintiffs"), filed an action in the Commonwealth of
Massachusetts Superior Court, Department of the Trial Court in and for the

County of Suffolk on July 27, 1995, for damages and declaratory relief against a
lessee of the Partnership, National Steel Corporation ("National Steel"). The
Complaint sought reimbursement from National Steel of certain sales and/or use
taxes paid to the State of Illinois in connection with equipment leased by
National Steel from the Plaintiffs and other remedies provided under the Master
Lease Agreement ("MLA"). On August 30, 1995, National Steel filed a Notice of
Removal, which removed the case to United States District Court, District of
Massachusetts. On September 7, 1995, National Steel filed its Answer to the
Plaintiff's Complaint along with Affirmative Defenses and Counterclaims and
sought declaratory relief, alleging breach of contract, implied covenant of good
faith and fair dealing, and specific performance. The Plaintiffs filed an Answer
to National Steel's Counterclaims on September 29, 1995. The parties discussed
settlement with respect to this matter for some time; however, the negotiations
were unsuccessful. The Plaintiffs filed an Amended and Supplemental Complaint
alleging further default under the MLA and filed a motion for Summary Judgment
on all claims and Counterclaims. The Court held a hearing on the Plaintiff's
motion in December 1997 and later entered a decision dismissing certain of
National Steel's Counterclaims, finding in favor of the Plaintiffs on certain
issues and in favor of National Steel on other issues. On May 11, 1999, the
parties executed a comprehensive settlement agreement to resolve all outstanding
issues, including reimbursement to the Partnership for the disputed sales tax
items referenced above. This matter did not have a material effect on the
Partnership's financial position or results of operations.

NOTE 7 - SUBSEQUENT EVENT

   On March 8, 2000, the Exchange Partnerships (see Note 6) collectively loaned
$32 million to Echelon Residential Holdings LLC, a newly-formed real estate
development company that will be owned by several investors, including James A.
Coyne, Executive Vice President of EFG. Mr. Coyne, in his individual capacity,
is the only investor in Echelon Residential Holdings LLC who is related to EFG.

   The Partnership's participation in the loan is $1,310,000. Echelon
Residential Holdings LLC, through a subsidiary (Echelon Residential LLC),
used the loan proceeds to acquire various real estate assets from Echelon
International Corporation, a Florida based real estate company. The loan has
a term of 30 months maturing on September 7, 2002 and bears interest at the
annual rate of 14% for the first 24 months and 18% for the final six months
of the term. Interest accrues and compounds monthly but is not payable until
maturity. In connection with the transaction, Echelon Residential Holdings
LLC has pledged a security interest in all of its right, title and interest
in and to its membership interests in Echelon Residential LLC to the Exchange
Partnerships as collateral.

         SCHEDULE OF EXCESS (DEFICIENCY) OF TOTAL CASH GENERATED TO COST
                              OF EQUIPMENT DISPOSED

              for the years ended December 31, 1999, 1998 and 1997

   The Partnership classifies all rents from leasing equipment as lease revenue.
Upon expiration of the primary lease terms, equipment may be sold, rented on a
month-to-month basis or re-leased for a defined period under a new or extended
lease agreement. The proceeds generated from selling or re-leasing the
equipment, in addition to any month-to-month revenue, represent the total
residual value realized for each item of equipment. Therefore, the financial
statement gain or loss, which reflects the difference between the net book value
of the equipment at the time of sale or disposition and the proceeds realized
upon sale or disposition may not reflect the aggregate residual proceeds
realized by the Partnership for such equipment.

   The following is a summary of cash excess associated with equipment
dispositions occurring in the years ended December 31, 1999, 1998 and 1997.
