                                              ===========      ===========

Due to cash flow problems experienced during 1997 by a lessee of the
Partnership, North American Communications Group, Inc. ("NACG"), the
Partnership, in an attempt to protect the assets leased to NACG, advanced funds
to various entities to whom NACG owed money related to the operation of such
leased assets. In addition, the Partnership assisted in arranging a management
agreement between NACG and another entity to attempt to improve NACG's cash flow
generated by the leased assets. In spite of the funds advanced by the
Partnership and the management agreement, the cash flow of NACG continued to
deteriorate. The General Partner actively solicited bids from parties to
purchase the assets associated with the Partnership leases to NACG. Based on the
value of similar assets and contract sites, management believed the equipment
leased to NACG had substantial value. However, the offers received were not
adequate to cover additional funds that were required to be advanced to keep the
equipment sites operating. The General Partner, therefore, determined it was no
longer economically feasible to continue to advance funds on behalf of NACG,
discontinued doing so and informed all site operators of that decision. As a
result, the Partnership decided to provide for a specific allowance of
$3,319,159 at December 31, 1997, which was equal to the carrying value of the
leases and advances associated with NACG. The Partnership foreclosed on the
assets underlying the leases and charged-off the lease receivables to the
specific allowance during 1998. 

The Partnership and an affiliated partnership, Telecommunications Income Fund
IX, have initiated a foreclosure action against NACG and the guarantors under
the leases and advances seeking the sale of the assets and a judgment against
NACG and the guarantors for any deficiency. The Partnership received a
settlement of $105,000 in the first quarter of 1999, and credited this to the
allowance for possible loan and lease losses.

Note C -- CREDIT ARRANGEMENTS

The Partnership has a line-of-credit agreement with a bank that carries interest
at 1% over prime (8.75% at March 31, 1999). The agreement was amended August 26,
1998 to extend the maturity date to June 30, 2000, reduce the borrowing amount
to the lesser of $4.0 million, or 40% of the Partnership's Qualified Accounts,
as defined in the agreement, and require minimum monthly interest payments of
$4,000 beginning in December 1998. The agreement is cancelable by the lender
after giving a 90-day notice and is collateralized by substantially all assets
of the Partnership. The line-of-credit is guaranteed by the General Partner and
certain affiliates of the General Partner. The General Partner believes amounts
available under the line of credit are adequate for the foreseeable future.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS
                                                    Three Months Ended
   Description                               March 31, 1999   March 31, 1998

       Gain on lease terminations                   1,735          158,834
       Management fee expense                      54,888           67,144
       Interest expense                            34,867          154,624
       Provision for possible losses               64,103           13,002
       Other expenses                              18,155           53,982

Lease and interest income decreased for the three-month period ended March 31,
1999 as compared to the same period in 1998 due to a decrease in the net
investment in direct financing leases and notes receivable. The decrease in net
investment in direct financing leases is attributable to the early termination
of certain leases in 1998 at the request of the lessees and the write-off of the
NACG leases discussed in Note B to the financial statements. The early
terminations enabled the Partnership to recognize gains on terminations of
$158,834 in the first quarter of 1998. The net investment in leases and notes
decreased from $17,575,044 at March 31, 1998 to $13,065,419 at March 31, 1999.

Net Income for the first quarter of 1999 was $225,532, while comprehensive
income was $790,223. The difference of $564,691 is attributable to the
unrealized gain on available-for-sale securities. The Partnership owns two
securities and carries these on the balance sheet at fair value, recording the
unrealized gain as an increase to partners' equity. One security increased in
value $566,100, while the other decreased in value $1,409.

Management fees are paid to the General Partner and represent 5% of the gross
rental payments received. Rental payments decreased from $1,342,880 in the three
months ended March 31, 1998 to $1,097,760 for the three months ended March 31,
1999. These decreases are attributed to the early termination of certain leases
as described above.

The decrease in interest expense is a result of the Partnership's lower loan
balances in the 1st quarter of 1999 compared to the same period in 1998. At
March 31, 1998 the balance on the line of credit was $3,939,570, while at March
31, 1999 the balance was $2,292,926. The Partnership had notes payable of
$370,780 outstanding at March 31, 1998 which were paid off in their entirety in
1998, resulting in less interest expense.

The provision for possible losses increased for the first quarter of 1999
compared to the same period a year ago due to the acquisition of leases in 1999.
As discussed in Note B to the financial statements, the Partnership received a
settlement from NACG in the amount of $105,000 in the first quarter of 1999, and
credited this to the allowance for possible loan and lease losses. The
Partnership provides for an estimated reserve, which was $548,421 at March 31,
1999, or 4.2% of the lease and notes receivable portfolio of $13,065,419. The
General Partner has determined all loss reserves are adequate at March 31, 1999.
The General Partner has established general and specific loss reserves as
follows:

                                           March 31, 1999   March 31, 1998

At March 31, 1999, one customer was past due over 90 days. The contract balance
remaining for this customer was $25,343 at March 31, 1999, while the
Partnership's net investment in this contract was $22,245. When a payment is
past due more than 90 days, the Partnership discontinues recognizing income on
the contract.

Other expenses decreased primarily due to $25,761 of costs incurred in the first
quarter of 1998 as a result of the foreclosure action against NACG as discussed
in note B to the financial statements.

The Partnership's portfolio of leases and notes receivable are concentrated in
pay telephones, office and computer equipment, and ATM machines, representing
approximately 52%, 21%, and 17%, respectively, of the portfolio at March 31,
1999. Four lessees account for approximately 64% of the Partnership's portfolio
at March 31, 1999.

YEAR 2000 ISSUE: The Partnership recognizes that the arrival of the Year 2000
poses a unique challenge to the ability of all systems to recognize the date
change from December 31, 1999 to January 1, 2000. The costs of ensuring systems
are compatible with the Year 2000 are not believed to be material. There are no
non-information technology processes that the Partnership has identified which
would affect its operations. An assessment of the readiness of external entities
which it interfaces with, such as vendors, counterparties, customers, and
others, is ongoing. At present the 



                                       9


   10


Partnership does not contemplate that any specific charges will be incurred for
this assessment or any other costs directly related to fixing Year 2000 issues,
and if there are any related expenditures, does not expect them to be
significant.

The Partnership is assessing the impact of the Year 2000 issue on information
technology and non-information technology systems used by lessees. No lessee is
contractually obligated to become Year 2000 compliant or to disclose their
capabilities to the Partnership. The Partnership has not yet determined whether
the Year 2000 issue has been addressed by all of its customers. The Partnership
has contacted some of its customers and will continue to contact its customers
in 1999. In a worst case scenario, the inability of lessees to be Year 2000
compliant could result in delayed or no payment of amounts due to the
Partnership. The Partnership has no contingency plans at this time to alleviate
this worst case scenario should it be encountered.

The Partnership has determined that the software it utilizes in its operations
is compatible with the Year 2000. The Partnership utilizes an unrelated third
party for lease servicing. This third party vendor has been contacted and it has
been determined that their lease servicing application is year 2000 compliant. A
written confirmation regarding compliance of this application has been received
from the software developer.

The Partnership has a line-of-credit agreement with a bank that carries interest
at 1% over prime (8.75% at March 31, 1999). The agreement was amended August 26,
1998 to extend the maturity date to June 30, 2000, reduce the borrowing amount

after giving a 90-day notice and is collateralized by substantially all assets
of the Partnership. The line-of-credit is guaranteed by the General Partner and
certain affiliates of the General Partner. The General Partner believes amounts
available under the line of credit are adequate for the foreseeable future.

The Partnership is required to establish working capital reserves of no less
than 1% of the proceeds to satisfy general liquidity requirements, operating
costs of equipment, and the maintenance and refurbishment of equipment. These
funds are available under the Partnership's line of credit.

At March 31, 1999, adequate cash is being generated to make projected
distributions, however, net income continues to remain below amounts
distributed.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
EQUITY PRICE SENSITIVITY
The table provides information about the Partnership's marketable equity
securities that are sensitive to changes in prices. The table presents the
carrying amount and fair value at March 31, 1999.

                                              ===========      ===========

The Partnership's primary market risk exposure with respect to marketable equity
securities is equity price. The Partnership's general strategy in owning
marketable equity securities is long-term growth in the equity value of emerging
companies in order to increase the rate of return to the limited partners over
the life of the Partnership. The primary risk of the portfolio is derived from
the underlying ability of the companies invested in to satisfy debt obligations
and their ability to maintain or improve common equity values. At March 31,
1999, the amount at risk was $2,016,637.

INTEREST RATE SENSITIVITY
The table below provides information about the Partnership's notes receivable
that are sensitive to changes in interest rates. For notes receivable, the table
presents principal cash flows and related weighted average interest by expected
maturity dates as of March 31, 1999.

The Partnership manages interest rate risk, its primary market risk exposure
with respect to notes receivable, by limiting the terms of notes receivable to
no more than five years and generally requiring full repayment ratably over the
term of the note.
