NOTES TO THE FINANCIAL STATEMENTS

June 30, 2000
(Unaudited)

Note 1--Basis of Presentation

The financial statements presented herein are prepared in conformity with
generally accepted accounting principles for interim financial information and
with the instructions for preparing Form 10-Q under Rule 10-01 of Regulation S-
X of the Securities and Exchange Commission and are unaudited. As such, these
financial statements do not include all information and footnote disclosures
required under generally accepted accounting principles for complete financial
statements and, accordingly, the accompanying financial statements should be
read in conjunction with the footnotes presented in the 1999 Annual Report.
Except as disclosed herein, there have been no material changes to the
information presented in the footnotes to the 1999 Annual Report.

In the opinion of management, all adjustments (consisting of normal and
recurring adjustments) considered necessary to present fairly the financial
position at June 30, 2000 and December 31, 1999 and results of operations for
the three and six month periods ended June 30, 2000 and 1999 have been made and
are reflected.

Note 2--Cash

At June 30, 2000, American Income Fund I-B, a Massachusetts Limited
Partnership (the "Partnership") had $672,715 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.

Note 3--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 Equis Financial Group Limited Partnership ("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 to the
financial statements presented in the Partnership's 1999 Annual Report
regarding the Class Action Lawsuit. Future minimum rents of $152,182 are due as
follows:

For the year ending June 30, 2001..................................... $112,906

2002................................................... 28,634
2003................................................... 10,642
--------
Total.................................................. $152,182

Note 4--Equipment

The following is a summary of equipment owned by the Partnership at June 30,
2000. Remaining Lease Term (Months), as used below, represents the number of
months remaining from June 30, 2000 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.

==========

At June 30, 2000, the Partnership's equipment portfolio included equipment
having a proportionate original cost of $151,529, representing approximately
13% of total equipment cost.

At June 30, 2000, all of the Partnership's equipment was subject to
contracted leases or being leased on a month-to-month basis.

Note 5--Investment in Real Estate Venture

On March 8, 2000, the Partnership and 10 affiliated partnerships (the
"Exchange Partnerships") collectively loaned $32.0 million to Echelon
Residential Holdings LLC ("Echelon Residential Holdings"), a newly formed real
estate development company. Echelon Residential Holdings is owned by several
investors, including James A. Coyne, Executive Vice President of EFG. Mr.
Coyne, in his individual capacity, is the only equity investor in Echelon
Residential Holdings related to EFG.

The Partnership's participation in the loan is $1,310,000. Echelon
Residential Holdings, through a wholly-owned 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 8, 2002, and an annual interest rate
of 14% for the first 24 months and 18% for the final six months. Interest
accrues and compounds monthly and is payable at maturity. In connection with
the transaction, Echelon Residential Holdings 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.

Using the guidance set forth in the Third Notice to Practitioners by the
American Institute of Certified Public Accountants ("AICPA") in February 1986
entitled "ADC Arrangements" (the "Third Notice"), the Partnership has evaluated
this investment to determine whether loan, joint venture or real estate
accounting is appropriate. Such determination affects the Partnership's balance
sheet classification of the investment and the recognition of revenues derived
therefrom. The Third Notice was issued to address those real estate
acquisition, development and construction arrangements where a lender has
virtually the same risk and potential awards as those of owners or joint
ventures. Emerging Issues Task Force ("EITF") 86-21, "Application of the AICPA
Notice to Practitioners regarding Acquisition, Development and Construction
Arrangements to Acquisition of an Operating Property" expanded the
applicability of the Third Notice to entities other than financial
institutions.

Based on the applicability of the Third Notice, EITF 86-21 and consideration
of the economic substance of the transaction, the loan is considered to be an
investment in a real estate venture for accounting purposes. In accordance with
the provisions of Statement of Position No. 78-9, "Accounting for Investments
in Real Estate Ventures", the Partnership reports its share of income or loss
of Echelon Residential Holdings under the equity method of accounting.

AMERICAN INCOME FUND I-B,
a Massachusetts Limited Partnership

NOTES TO THE FINANCIAL STATEMENTS--(Continued)

The Partnership's March 31, 2000 Form 10-Q previously reported the
investment in real estate venture as a loan receivable and recorded interest
income and receivable on the Partnership's March 31, 2000 financial statements.
The financial statements below have been adjusted to account for the loan as an
investment in real estate venture as of and for the three months ended March
31, 2000. The adjustments to the financial statements previously filed in the
Partnership's March 31, 2000 Form 10-Q represent less than 1% of the
Partnership's capital and include the reversal of $12,227 of interest income
recorded on this loan and a recognition of $1,282 for the Partnership's share
of losses in Echelon Residential Holdings.

Note 7--Legal Proceedings

As described more fully in the Partnership's Annual Report on Form 10-K for

FORM 10-Q

PART I. FINANCIAL INFORMATION

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

Certain statements in this quarterly 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 financial
statements presented in the 1999 Annual Report, the remarketing of the
Partnership's equipment, and the performance of the Partnership's non-equipment
assets.

Three and six months ended June 30, 2000 compared to the three and six months
ended June 30, 1999

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 financial statements presented in the
Partnership's 1999 Annual Report. 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.

Results of Operations

For the three and six months ended June 30, 2000, the Partnership recognized
lease revenue of $44,731 and $125,813, respectively, compared to $80,743 and
$154,136, respectively, for the same periods in 1999. The decrease in lease
revenue from 1999 to 2000 is primarily the result of lease term expirations and
the sale of equipment. In the future, lease revenue will decline due to lease
term expirations and the sale of equipment.

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 Equis Financial Group Limited Partnership ("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.

Interest income for the three and six months ended June 30, 2000 was $11,732
and $36,091 compared to $28,468 and $48,944 for the same periods in 1999.
Interest income is typically generated from temporary investment of rental
receipts and equipment sale proceeds in short-term instruments. On March 8,
2000, the Partnership utilized $1,310,000 of available cash for a loan to
Echelon Residential Holdings LLC ("Echelon Residential Holdings"). (See Note 5
to the financial statements herein.) The amount of future interest income is
expected to fluctuate as a result of changing interest rates and the amount of
cash available for investment, among other factors.

During each of the three and six month periods ended June 30, 2000 and June
30, 1999, the Partnership sold fully depreciated equipment resulting in a net
gain, for financial statement purposes, of $5,389 and $9,850, respectively. 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 upon final disposition of 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 for the three and the six months ended June 30, 2000
was $22,070 and $44,139, respectively, compared to $25,668 and $51,334,
respectively, for the same periods in 1999. 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.

Management fees were $1,390 and $4,597 for the three and six month periods
ended June 30, 2000, respectively, compared to $2,703 and $5,307, respectively,
for the same periods in 1999. 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 $34,351 and $77,175, respectively, for the three and
six months ended June 30, 2000, compared to $71,490 and $113,879, respectively,
for the same periods in 1999. Operating expenses in 1999 include an adjustment
for 1998 actual administrative charges and third-party costs of approximately
$29,000. Operating expenses consist principally of administrative charges,
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.

For the three and six months ended June 30, 2000, the Partnership's share of
losses in Echelon Residential Holdings were $7,117 and $8,399, respectively,
and are reflected on the Statement of Operations as "Partnership's share of
unconsolidated real estate venture's loss". See further discussion below.

Liquidity and Capital Resources and Discussion of Cash Flows

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. Operating activities generated net cash inflows of
$62,585 and $114,060 in the six months ended June 30, 2000 and 1999,
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. Overall, expenses associated with rental activities, such as
management fees, and net cash flow from operating activities will also decline
as the Partnership experiences a higher frequency of remarketing events. See
additional discussion below regarding the loan made by the Partnership to
Echelon Residential Holdings in March 2000.

Cash realized for asset disposal transactions is reported under investing
activities on the accompanying Statement of Cash Flows. For the six months
ended June 30, 2000, the Partnership realized $5,389 in equipment sales
proceeds compared to $9,850 for the same period in 1999. 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 June 30, 2000, the Partnership was due aggregate future minimum lease
payments of $152,182 from contractual lease agreements. 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.

In connection with a preliminary settlement agreement for the Class Action
Lawsuit described in Note 6 to the financial statements presented in the
Partnership's 1999 Annual Report, the Partnership is permitted to invest in new
equipment or other business activities, subject to certain limitations. On
March 8, 2000, the Partnership and 10 affiliated partnerships (the "Exchange
Partnerships") collectively loaned $32.0 million to Echelon Residential
Holdings, a newly-formed real estate development company owned by several
investors, including James A. Coyne, Executive Vice President of EFG. Mr.
Coyne, in his individual capacity, is the only equity investor in Echelon
Residential Holdings related to EFG.

The Partnership's participation in the loan is $1,310,000. Echelon
Residential Holdings, 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 8, 2002 and bears interest at the annual rate of
14% for the first 24 months and 18% for the final six months. Interest accrues
and compounds monthly and is payable at maturity. In connection with the
transaction, Echelon Residential Holdings 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.

As discussed in Note 5 in the Partnership's financial statements, the loan
is considered to be an investment in a real estate venture for accounting
purposes. In accordance with the provisions of Statement of Position No. 78-9,
"Accounting for Investments in Real Estate Ventures", the Partnership reports
its share of income or loss of Echelon Residential Holdings under the equity
method of accounting.

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 had 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. No cash distributions were declared for
the six months ended June 30, 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 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 June 30, 2000. 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 financial
statements presented in the Partnership's 1999 Annual Report 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 suspended 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.
