Results of Operations and Liquidity and Capital Resources

American Income Partners IV-B Limited Partnership (the Partnership) was
established in 1988 as a direct-participation equipment leasing program. The
Partnership's principal purpose was (i) to acquire and lease a diversified
portfolio of capital equipment to third-party lessees and (ii) to distribute the
net cash flow realized from the Partnership's business operations to its
Partners. The Partnership was capitalized with equity contributions of
$21,848,375 from its Recognized Owners and $1,000 from its Managing General
Partner. Following its inception, the Partnership acquired a diversified pool of
capital equipment at an aggregate cost of $32,106,352, a significant portion of
which was financed by third-party banks or other institutional lenders. On
September 30, 1996, the Partnership sold substantially all of its assets and
thereafter wound up its operations. The Partnership was dissolved on December
31, 1996.

Organized as a limited-life entity, the Partnership was anticipated to be
dissolved within approximately seven years of its formation. A significant
portion of the Partnership's equipment assets, representing 75% of its original
equipment portfolio, was sold in the ordinary course of business prior to
September 30, 1996. On September 30, 1996, the remainder of the Partnership's
equipment portfolio was sold to RSL Finance Limited Partnership II (the Buyer).
Accordingly, the financial statements accompanying this discussion were prepared
using the liquidation basis of accounting for the period October 1, 1996 through
December 31, 1996. The Statement of Changes in Net Assets in Liquidation
reflects the liquidation of assets during that period.

A comparison of current and prior years' financial results is not presented
because it is not considered meaningful due the dissolution of the Partnership
and the liquidation of its assets.

Prior to its dissolution, the Partnership's principal sources of revenue
consisted of rental income from equipment leases and sales proceeds generated
from the disposition of its equipment assets. Rental income was used first to
extinguish indebtedness and second to pay the Partnership's management fees and
operating expenses. Net cash flow from all sources, after satisfaction of debt
service, management fees and operating expenses, was used to pay cash
distributions to the Partners. Over its lifetime, the Partnership paid aggregate
cash distributions of $21,453,332. In accordance with the Partnership's Amended
and Restated Agreement and Certificate of Limited Partnership, the Partnership's
Recognized Owners were paid 99% of such cash distributions, or $21,238,799
($24.30 per unit) and the General Partners were paid 1% of such distributions,
or $214,533. At December 31, 1996, the Partnership had a contingency reserve
balance of $375,274. These funds will be used to satisfy any expenses of the
Partnership which may arise after its dissolution date. To the extent that these
funds are not utilized for such purposes, they will be paid to the Partners
according to their respective allocation percentages, 99%, or $371,521,
representing $0.43 per unit, to the Recognized Owners and 1%, or $3,753, to the
General Partners.

During the second quarter of 1996, the Partnership engaged an investment adviser
to solicit potential buyers for the Partnership's remaining equipment assets and
associated lease contracts. The remarketing effort was undertaken jointly by 15
individual equipment leasing programs, consisting of the Partnership and 14
affiliated partnerships (the Other Affected Partnerships). Thirteen of the
programs, including the Partnership, sold all of their equipment assets (the
Liquidated Programs); and two programs sold only their proportionate ownership
interests in certain assets owned jointly with one or more of the Liquidated
Programs (collectively, the Sale Assets). Substantially all of the Partnership's
equipment assets of material value represented partial ownership interests
whereby the Partnership owned less than a 100% interest in the equipment it
sold. The remaining interests in such assets were owned by one or more of the
Other Affected Partnerships.

On September 30, 1996, the Partnership and each of the Other Affected
Partnerships executed individual purchase and sale agreements with the Buyer for
all of the Sale Assets, except for one McDonnell Douglas MD-82 aircraft leased
to Northwest Airlines, Inc. (the NWA Aircraft), hereafter the Sales Assets, as
Revised. The NWA Aircraft, in which the Partnership owned a proportionate
interest of 14.5%, was purchased by the lessee pursuant to a separate
negotiation. The Partnership realized $1,332,848 of net sale proceeds for the
Sale Assets, as Revised and $1,890,800 for the NWA Aircraft. The latter included
early termination rental payments of $235,625 from the lessee. At the date of
sale, the Sale Assets, as Revised and the NWA Aircraft had net book values of
$1,187,754 and $1,771,276, respectively. In aggregate, the Partnership and the
Other Affected Partnerships realized, prior to transaction costs, $32,997,000
for all of the Sale Assets, as Revised and $13,200,000 for the NWA Aircraft. Net
proceeds from the NWA Aircraft were allocated to the owners of the NWA Aircraft
according to their respective percentage ownership interests. Net proceeds from
the Sale Assets, as Revised were allocated to the Partnership and to each of the
Other Affected Partnerships based upon an apportionment of the sales price among
all equipment comprising the Sale Assets, as Revised according to each asset's
estimated re-sale value, as determined by an independent appraiser. For
financial reporting purposes, the Partnership recognized a net gain of $28,993
in connection with both sale transactions. In addition, the Partnership
recognized a net gain of $49,409 during the nine months ended September 30, 1996
from the sale of other equipment, all of which had been fully depreciated for
financial reporting purposes at the date of sale.

For the year ended December 31, 1996, the Partnership recognized lease revenue
of $864,299. In addition, the Partnership earned interest income from temporary
cash investments. Operating expenses consisted principally of administrative
charges, professional service costs, such as legal and accounting fees, as well
as printing, distribution, and remarketing expenses, including equipment storage
and repairs and maintenance costs. Operating costs for 1996 include all
identified costs anticipated to be incurred in connection with the Partnership's
wind-up and dissolution.

On October 10, 1996, the Managing General Partner entered into a Cross
Partnership Agreement (the Agreement) with the general partners of certain of
the Other Affected Partnerships participating in the sales transactions
described above. Pursuant to the Agreement, the Partnership and each of the
other partnerships agreed to set aside a contingency reserve for future
liabilities. The Agreement provides that obligations of any individual
partnership which are not associated with the sales transactions will directly
reduce that partnership's reserve balance, whereas costs pertaining to the sales
transactions will be allocated against the reserve balances of the Partnership
and each of the other partnerships on a proportionate basis. If the reserve
balance of the Partnership is depleted to zero, the reserve balances contributed
by the other partnerships will be debited on a proportionate basis to cover the
deficit. If the reserve balances of any one of the other partnerships is
depleted to zero, the reserve balance of the Partnership and any other
partnerships having a positive reserve balance shall be debited on a
proportionate basis to cover the deficit. Upon termination of


                                       4
<PAGE>

the Agreement, any remaining monies will be distributed to the partners of those
partnerships with positive reserve balances. At December 31, 1996, the
Partnership had a contingency reserve balance of $375,274. To the extent that
this contingency reserve is not necessary to satisfy any unforeseen liabilities
of the Partnership, it will be remitted to the Partners.

The dissolution of the Partnership was recorded at the Office of the Secretary
of State of the Commonwealth of Massachusetts on December 31, 1996. The
Partnership's business operations were concluded on that date. Immediately
following the filing of the Partnership's 1996 Form 10-K, the Managing General
Partner of the Partnership will file Form 15, Certification and Notice of
Termination of Registration under Section 12(g) of the Securities Exchange Act
of 1934 or Suspension of Duty to File Reports Under Sections 13 and 15(d) of the
Securities Exchange Act of 1934, with the United States Securities and Exchange
Commission.

                         REPORT OF INDEPENDENT AUDITORS

To the Partners of American Income Partners IV-B Limited Partnership:

We have audited the accompanying statement of financial position of American
Income Partners IV-B Limited Partnership as of December 31, 1995, and the
related statements of operations, changes in partners' capital and cash flows
for each of the two years ended December 31, 1995 and for the period from
January 1, 1996 to September 30, 1996. In addition, we have audited the
statement of changes in net assets in liquidation for the period from October 1,
1996 to December 31, 1996. 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 generally accepted auditing
standards. 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.

As described in Note 1 to the financial statements, the Managing General Partner
of American Income Partners IV-B Limited Partnership approved a plan of
liquidation on September 30, 1996, and the Partnership commenced liquidation
shortly thereafter. As a result, the Partnership has changed its basis of
accounting for periods subsequent to September 30, 1996 from the going-concern
basis to a liquidation basis. The liquidation was completed and the Partnership
was dissolved on December 31, 1996.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of American Income Partners IV-B
Limited Partnership as of December 31, 1995, the results of its operations and
its cash flows for each of the two years ended December 31, 1995, and for the
period from January 1, 1996 to September 30, 1996, and the changes in its net
assets in liquidation for the period from October 1, 1996 to December 31, 1996,
in conformity with generally accepted accounting principles applied on the bases
described in the preceding paragraph.

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.

                                DECEMBER 31, 1996

(1)    ORGANIZATION AND PARTNERSHIP MATTERS

       Organization

       The Partnership was organized as a limited partnership under the
       Massachusetts Uniform Limited Partnership Act (the Uniform Act) on
       September 29, 1988, 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 Managing General
       Partner (AFG Leasing IV Incorporated) and $100 from the Initial Limited
       Partner (AFG Assignor Corporation). On December 29, 1988, the Partnership
       issued 873,935 units, representing assignments of limited partnership
       interests (the Units) to 1,331 investors. Unitholders and Limited
       Partners (other than the Initial Limited Partner) are collectively
       referred to as Recognized Owners. On December 31, 1996, the General
       Partners of the Partnership caused the Partnership's Amended and Restated
       Agreement and Certificate of Limited Partnership (the Restated Agreement,
       as amended) to be canceled by filing a Certificate of Cancellation with
       the Massachusetts Secretary under the Uniform Act. Accordingly, the
       Partnership was dissolved on December 31, 1996.

       The Partnership originally had four General Partners: AFG Leasing IV
       Incorporated, a Massachusetts corporation established in 1987 and a
       wholly-owned subsidiary of American Finance Group (AFG), a Massachusetts
       general partnership, which subsequently became Equis Financial Group
       Limited Partnership (collectively referred to herein as AFG), Daniel J.
       Roggemann, Martin F. Laughlin, and Geoffrey A. MacDonald (collectively
       the General Partners). Messrs. Roggemann and Laughlin subsequently
       elected to withdraw as Individual General Partners. AFG Leasing IV
       Incorporated is also the general partner or managing general partner of
       certain affiliated partnerships sponsored by AFG.

       Significant operations commenced December 30, 1988 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 were allocated 99% to the Recognized Owners
       and 1% to the General Partners.

       Under the terms of a Management Agreement between the Partnership and
       AF/AIP Programs Limited Partnership and the terms of an identical
       management agreement between AF/AIP Programs Limited Partnership and AFG
       (collectively, the Management Agreement), management services were
       provided by AFG to the Partnership at fees which the Managing General
       Partner believed to be competitive for similar services (Also see Note
       4).

                                   (Continued)

(1)    ORGANIZATION AND PARTNERSHIP MATTERS (Continued)

       Organization (Continued)

       Equis Financial Group Limited Partnership (Equis) is a Massachusetts
       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. Equis and its subsidiaries (collectively, the Company) are engaged
       in various aspects of the equipment leasing business, including Equis'
       role as Equipment Manager or Advisor to the Partnership and several other
       Direct-Participation equipment leasing programs sponsored or co-sponsored
       by AFG (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 Equis, with a 1% controlling interest, is Equis
       Corporation, a Massachusetts corporation owned and controlled entirely by
       Gary D. Engle, its President and Chief Executive Officer. Equis
       Corporation also owns a controlling 1% general partner interest in Equis'
       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 (the Buyer).
       AFG changed its name to Equis Financial Group Limited Partnership after
       the sale was concluded. Pursuant to terms of the sale agreements, Equis
       agreed not to compete with the Buyer's lease origination business for a
       period of five years; however, Equis is permitted to originate certain
       equipment leases, principally those involving noninvestment grade lessees
       and ocean-going vessels, which are not in competition with the Buyer. In
       addition, the sale agreements specifically reserved to Equis 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, including the right to satisfy all required
       equipment acquisitions utilizing either brokers or the Buyer. Geoffrey A.
       MacDonald, Chairman of Equis Corporation and Gary D. Engle agreed not to
       compete with the sold business on terms and conditions similar to those
       for the Company.

(1)    ORGANIZATION AND PARTNERSHIP MATTERS (Continued)

       Basis of Presentation

       On September 30, 1996, the Partnership sold all of its remaining
       equipment assets, excluding its interest in an aircraft, for $1,332,848.
       In October 1996, the Partnership filed Form 8-K, which provided a
       description of the remarketing process and the terms of sale. The entire
       remarketing effort was undertaken jointly by 15 individual equipment
       leasing programs, consisting of the Partnership and 14 affiliated
       partnerships, each of which individually executed separate purchase and
       sale agreements with RSL Finance Limited Partnership II (the Buyer) and
       certain of which entered into a collective purchase and sale agreement
       with Northwest Airlines, Inc. (NWA), to sell all or a portion of their
       equipment assets (the Sale Assets). These proceeds were first used to
       repay the entire outstanding balance due under the notes payable and the
       associated interest of $85,104 and $1,024, respectively. Certain of these
       partnerships, including the Partnership, sold their collective interest
       in a McDonnell Douglas MD-82 aircraft (NWA Aircraft) to NWA. The net
       consideration for this aircraft was allocated first to remaining lease
       rental obligations and second to sale proceeds. The Partnership's
       proportionate share of this consideration was $1,890,800 and $1,655,175
       representing net sale proceeds. (See Note 4.)

       On October 15, 1996, the Partnership paid a cash distribution of
       $3,268,426 of which $3,235,742 was paid to the Limited Partners and
       $32,684 was paid to the Managing General Partner. As discussed in Note 4,
       the Partnership had a contingency reserve of $375,274 at December 31,
       1996.

       The Managing General Partner approved a plan of liquidation on September
       30, 1996 and commenced liquidation on October 1, 1996. On December 31,
       1996, the Managing General Partner dissolved the Partnership in
       accordance with the Restated Agreement, as amended.

       The financial statements presented have been prepared on a going-concern
       basis through September 30, 1996. Due to the ultimate dissolution of the
       Partnership requiring liquidation and distribution of its net assets, the
       Partnership changed its basis of accounting from going-concern to
       liquidation basis effective October 1, 1996. Liquidation basis requires
       that statements be prepared based on anticipated liquidating values of
       assets and liabilities.

(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       Statement of Cash Flows

       The Partnership considered liquid investment instruments purchased with a
       maturity of three months or less to be cash equivalents. From time to
       time, the Partnership invested excess cash with large institutional banks
       in reverse repurchase agreements with overnight maturities. Under the
       terms of the

       The securities underlying the agreements were book entry securities.

       Revenue Recognition

       Rents were payable to the Partnership monthly, quarterly or semi-annually
       and no significant amounts were calculated on factors other than the
       passage of time. The leases were accounted for as operating leases and
       were noncancellable. Rents received prior to their due dates were
       deferred. The Partnerships' entire equipment portfolio was sold on
       September 30, 1996. No future rents are due.

       Revenue from major individual lessees which accounted for 10% or more of
       lease revenue during each of the past three years is as follows:

       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.

       Equipment on Lease

       All equipment was acquired from AFG, one of its affiliates, including
       other equipment leasing programs sponsored by AFG, or from third-party
       sellers. Equipment cost represented asset base price plus acquisition
       fees and was determined in accordance with the Restated Agreement, as
       amended, and certain regulatory guidelines. Asset base price was affected
       by the relationship of the seller to the Partnership as summarized
       herein. Where the seller of the equipment was AFG or an affiliate, asset
       base price was the lower of (i) the actual price paid for the equipment
       by AFG or the affiliate plus all actual costs accrued by AFG or the
       affiliate while carrying the equipment less the amount of all rents
       earned by AFG or the affiliate prior to selling the equipment or (ii)
       fair market value as determined by

 (2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

       Equipment on Lease (Continued)

       the Managing General Partner in its best judgment, including all liens
       and encumbrances on the equipment and other actual expenses. Where the
       seller of the equipment was a third party who did not manufacture the
       equipment, asset base price was the lower of (i) the price invoiced by
       the third party or (ii) fair market value as determined by the Managing
       General Partner. Where the seller of the equipment was a third party who
       also manufactured the equipment, asset base price was the manufacturer's
       invoice price, which price was considered to be representative of fair
       market value.

       Depreciation

       The Partnership's depreciation policy was intended to allocate the cost
       of equipment over the period during which it produced economic benefit.
       The principal period of economic benefit was considered to correspond to
       each asset's primary lease term, which term generally represented the
       period of greatest revenue potential for each asset. Accordingly, to the
       extent that an asset was held on primary lease term, the Partnership
       depreciated 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 represented
       estimates of equipment values at the date of primary lease expiration. To
       the extent that an asset was held beyond its primary lease term, the
       Partnership continued to depreciate the remaining net book value of the
       asset on a straight-line basis over the asset's remaining economic life.

       Accrued Liabilities--Affiliate

       Unpaid operating expenses paid by AFG on behalf of the Partnership were
       reported as Accrued Liabilities--Affiliate. (See Note 4.)

       Allocation of Profits and Losses

       For financial statement purposes, net income or loss was allocated to
       each Partner according to their respective ownership percentages (99% to
       the Recognized Owners and 1% to the General Partners). See Note 5
       concerning allocation of income or loss for income tax purposes.

       Net Income and Cash Distributions Per Unit

       Net income and cash distributions per Unit were based on 873,935 limited
       partnership units outstanding during each of the three years in the
       period ended December 31, 1996, and computed after allocation of the
       General Partners' 1% share of net income and cash distributions.

 (2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

       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.

(3)    EQUIPMENT

       At September 30, 1996, the Partnership disposed of its entire equipment
       portfolio.

       As equipment was sold to third parties, or otherwise disposed of, the
       Partnership recognized 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.

(4)    RELATED PARTY TRANSACTIONS

       All operating expenses incurred by the Partnership were paid by AFG on
       behalf of the Partnership and AFG was reimbursed at its actual cost for
       such expenditures. Fees and other costs incurred during each of the three
       years in the period ended December 31, 1996, which were paid or accrued
       by the Partnership to AFG or its Affiliates, are as follows:

                                                  1996        1995        1994

       As provided under the terms of the Management Agreement, AFG was
       compensated for its services to the Partnership. Such services included
       all aspects of acquisition, management and sale of equipment. For
       acquisition services, AFG was compensated by an amount equal to 4.75% of
       Equipment Base Price paid by the Partnership. For management services,
       AFG was compensated by an amount equal to the lesser of (i) 5% of gross
       lease rental revenues earned by the Partnership or (ii) fees which the
       Managing General Partner reasonably believed to be competitive for
       similar services for similar equipment. Both of these fees were subject
       to certain limitations defined in the Management Agreement. As Payout was
       not achieved, AFG received no compensation for services connected to the
       sale of equipment under its subordinated remarketing agreement.

       Administrative charges represent amounts owed to AFG, pursuant to Section
       10.4 of the Restated Agreement, as amended, for persons employed by AFG
       who were engaged in providing administrative services to the Partnership.
       Reimbursable operating expenses due to third parties represent costs paid
       by AFG on behalf of the Partnership which were reimbursed to AFG.

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

       All rents and proceeds from the sale of equipment were paid directly to
       either AFG or to a lender. AFG temporarily deposited collected funds in a
       separate interest-bearing escrow account prior to remittance to the
       Partnership.

       On August 18, 1995, Atlantic Acquisition Limited Partnership (AALP), a
       newly formed Massachusetts limited partnership owned and controlled by
       certain principals of AFG, commenced a voluntary cash Tender Offer (the
       Offer) for up to approximately 45% of the outstanding units of limited
       partner interest in this Partnership and 20 affiliated partnerships
       sponsored and managed by AFG. The Offer was subsequently amended and
       supplemented in order to provide additional disclosure to unitholders;
       increase the offer price; reduce the number of units sought to
       approximately 35% of the outstanding units; and extend the expiration
       date of the Offer to October 20, 1995. Following commencement of the
       Offer, certain legal actions were initiated by interested persons against
       AALP, each of the general partners (4 in total) of the 21 affected
       programs, and various other affiliates and related parties. One action, a
       class action brought in the United States District Court for the District
       of Massachusetts (the Court) on behalf of the unitholders (Recognized
       Owners), sought to enjoin the Offer and obtain unspecified monetary
       damages. A settlement of this litigation was approved by the Court on
       November 15, 1995. The Plaintiffs filed an appeal in this matter. On
       November 26, 1996, the United States Court of Appeals for the First
       Circuit handed down a decision affirming the Court's approval of the
       settlement. A second class action, brought in the Superior Court of the
       Commonwealth of Massachusetts (the Superior Court) seeking to enjoin the
       Offer, obtain unspecified monetary damages, and intervene in the first
       class action, was dismissed by the Superior Court. The Recognized Owners
       of the Partnership tendered 85,141 units or 9.74% of the total
       outstanding units of the Partnership to AALP. In September 1996, AALP
       sold these units to Equis for $368,074.

                                   (Continued)

(4)    RELATED PARTY TRANSACTIONS (Continued)

       The remarketing effort described in Note 1 was undertaken jointly by 15
       individual equipment leasing programs, consisting of the Partnership and
       14 affiliated partnerships (Other Affected Partnerships). Thirteen of the
       programs, including the Partnership, sold all of their equipment assets
       (the Liquidated Programs); and two programs sold only their proportionate
       ownership interests in certain assets owned jointly with one or more of
       the Liquidated Programs. Substantially all of the Partnership's equipment
       assets of material value represented partial ownership interests whereby
       the Partnership owned less than a 100% interest in the equipment it sold.
       The remaining interests in such assets were owned by one or more of the
       Other Affected Partnerships.

       On September 30, 1996, the Partnership and each of the Other Affected
       Partnerships executed individual purchase and sale agreements with the
       Buyer for all of the Sale Assets, except for one McDonnell Douglas MD-82
       aircraft leased to Northwest Airlines, Inc., hereafter the Sale Assets,
       as Revised. The NWA Aircraft, in which the Partnership owned a
       proportionate interest of 14.5%, was purchased by the lessee pursuant to
       a separate negotiation. The Partnership realized $1,332,848 of net sale
       proceeds for the Sale Assets, as Revised and $1,890,800 for the NWA
       Aircraft. The latter included early termination rental payments of
       $235,625 from the lessee. At the date of sale, the Sale Assets, as
       Revised and the NWA Aircraft had net book values of $1,187,754 and
       $1,771,276, respectively. In aggregate, the Partnership and the Other
       Affected Partnerships realized, prior to transaction costs, $32,997,000
       for all of the Sale Assets, as Revised and $13,200,000 for the NWA
       Aircraft. Net proceeds from the NWA Aircraft were allocated to the owners
       of the NWA Aircraft according to their respective percentage ownership
       interests. Net proceeds from the Sale Assets, as Revised were allocated
       to the Partnership and to each of the Other Affected Partnerships based
       upon an apportionment of the sales price among all equipment comprising
       the Sale Assets, as Revised according to each asset's estimated re-sale
       value, as determined by an independent appraiser.

       The Buyer is a limited partnership established to acquire the Sale
       Assets, as Revised, and has no direct affiliation with the Partnership,
       the Other Affected Partnerships, the General Partners or AFG. The sole
       general partner of the Buyer is RSL Holdings, Inc. (RSL). An affiliate of
       RSL purchased a significant limited partnership interest in a
       direct-participation equipment leasing program co-sponsored by AFG in
       1992. AFG acquired this interest in 1993 for cash and assumption of
       indebtedness. There have been no other business dealings between the
       Buyer and AFG and their affiliates.

                                   (Continued)

(4)    RELATED PARTY TRANSACTIONS (Continued)

       On October 10, 1996, the Managing General Partner entered into a Cross
       Partnership Agreement (the Agreement) with the general partners of
       certain of the Other Affected Partnerships participating in the sales
       transactions described above. Pursuant to the Agreement, the Partnership
       and each of the other partnerships agreed to set aside a contingency
       reserve for future liabilities. The Agreement provides that obligations
       of any individual partnership which are not associated with the sales
       transactions will directly reduce that partnership's reserve balance,
       whereas costs pertaining to the sales transactions will be allocated
       against the reserve balances of the Partnership and each of the other
       partnerships on a proportionate basis. If the reserve balance of the
       Partnership is depleted to zero, the reserve balances contributed by the
       other partnerships will be debited on a proportionate basis to cover the
       deficit. If the reserve balances of any one of the other partnerships is
       depleted to zero, the reserve balance of the Partnership and any other
       partnerships having a positive reserve balance shall be debited on a
       proportionate basis to cover the deficit. Upon termination of the
       Agreement, any remaining monies will be distributed to the partners of
       those partnerships with positive reserve balances. At December 31, 1996,
       the Partnership had a contingency reserve balance of $375,274. To the
       extent that this contingency reserve is not necessary to satisfy any
       unforeseen liabilities of the Partnership, it will be remitted to the
       Partners.

(5)    INCOME TAXES

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

       For financial statement purposes, the Partnership allocated net income or
       loss to each class of partner according to their respective ownership
       percentages (99% to the Recognized Owners and 1% to the General
       Partners). This convention differed 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 allocated net income or loss in accordance with such
       agreement.

       The following is a reconciliation between net income reported for
       financial statement and federal income tax reporting purposes for the
       years ended December 31, 1996, 1995 and 1994:

                  SCHEDULE OF EXCESS (DEFICIENCY) OF TOTAL CASH
                     GENERATED TO COST OF EQUIPMENT DISPOSED
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

The Partnership classified all rents from leasing equipment as lease revenue.
Upon expiration of the primary lease terms, equipment was 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 revenues, represented 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 during the years ended December 31, 1996, 1995 and 1994.
