NOTE C - BORROWING AGREEMENTS
In January 1999, the Partnership obtained financing under a line of credit
agreement with a bank. The amount available to borrow under the line of credit
is $4,400,000 (limited by 32% of qualified accounts) and matures June 30, 2002.
The line of credit agreement bears interest at 1% over the prime rate, with a
$4,000 minimum monthly interest charge, 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. This agreement is
cancelable by the lender after giving a 90-day notice. The General Partner
believes amounts available under the line of credit are adequate for the
foreseeable future. The amount outstanding under this line of credit at
September 30, 2001 was $1,165,582.

NOTE D - NET INCOME (LOSS) PER PARTNERSHIP UNIT
Net income (loss) per partnership unit is based on the weighted average number
of units outstanding (including both general and limited partners), which were
12,573 and 12,593 for the nine months ended September 30, 2001, and 2000,
respectively. The weighted average number of units for the three months ended
September 30, 2001, and 2000, were 12,545 and 12,593, respectively.

NOTE E - CONTINGENCY
The General Partner has approximately $2,200,000 of notes payable and redeemable
preferred stock maturing in 2001 and may not have sufficient liquid assets to
repay such amounts. The General Partner is pursuing additional financing,
refinancing, and asset sales to meet its obligations. No assurance can be
provided that the General Partner will be successful in its efforts.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
RESULTS OF OPERATIONS
Income derived from direct financing leases and notes receivable was $782,420
for the nine months ending September 30, 2001 and $886,862 for the same period
of 2000. The net investment in direct financing leases and notes receivable was
$8,544,171 at September 30, 2001 and $13,461,720 at September 30, 2000.

In November 2000, the Partnership exercised its right to manage the assets
leased to Alpha Telecommunications, Inc. ("ATI") due to nonpayment of lease
receivables. The remaining net equipment cost, primarily pay phones, is expected
by management to be recovered through the operation and/or sale of the
equipment. The Partnership has engaged a company to oversee the operations of
the pay phone routes and to attempt to sell the equipment. Depreciation expense
on this equipment was $394,480 for the first three quarters of 2001. In March of
2001 the Partnership signed an agreement to sell a portion of these phones for
$286,114. The sale resulted in a loss of $115,475. The Partnership had a
tentative agreement to sell the remaining equipment and has written the
equipment down to its expected sales price and incurred an impairment loss of
$1,084,585. This sale was not consummated and the Partnership continues to
pursue buyers for the equipment. No assurance can be provided that the equipment
will be sold or that the carrying value of the equipment will be realized. The
Partnership also took an additional impairment loss of $100,000 on unrelated
equipment under operating lease to write the equipment down to its estimated
value.

Management fees are paid to the General Partner and represent 2% of the gross
rental payments, loan payments, and other financing payments received. These
fees were $59,025 the first nine months of 2001 compared to $105,650 for the
same period of 2000. The decreased management fees are due to a decrease in the
gross rental payments, loan payments, and other financing payments received.

Administrative services of $117,000 represent fees paid to the General Partner
for the operation of the Partnership as defined in the Partnership Agreement.
The Partnership pays the General Partner $13,000 per month for these services.
The increase in administrative fees paid is due to an increase in administrative
costs incurred by the General Partner on behalf of the Partnership.

Interest expense for the first nine months of 2001 was $106,561 compared to
$75,718 for the same period of 2000, and is the result of borrowings on the line
of credit, with the proceeds of the borrowings used to finance leases and notes
receivable. The balance outstanding on the line of credit at September 30, 2001
was $1,165,582.

At September 30, 2001, seven customers were past due over 90 days. When a
payment is past due more than 90 days, the Partnership discontinues recognizing
income on the contract. The Partnership's net investment in the past due
contracts was $2,660,517. The schedule below itemizes the past due contracts.
Management will continue to monitor the past due contracts and take the
necessary steps to protect the Partnership's investment. At September 30, 2001,
the allowance for possible losses was $1,098,461 and represents 12.9% of the
lease and note portfolio of $8,544,171.

The telecommunications industry has seen a significant downturn in the last year
that has adversely affected the Partnership. The allowance for possible losses
has been increased to reflect the downturn in the industry. The allowance for
possible losses has also been adjusted for customers past due over 90 days.
Management continually reviews its reserves and will make further adjustments as
needed.

The Partnership's portfolio of leases and notes receivable are concentrated in
pay telephones, office equipment, and industrial equipment, representing
approximately 48%, 16%, and 12%, respectively, of the portfolio at September 30,
2001. Two lessees account for approximately 22% of the Partnership's portfolio
at September 30, 2001. One of these customers is past due over 90 days, as
mentioned above and represents approximately 11% of the portfolio.

In January 1999, the Partnership obtained financing under a line of credit
agreement with a bank. The amount available to borrow under the line of credit
is $4,400,000 (limited by 32% of qualified accounts) and matures June 30, 2002.
The line of credit agreement bears interest at 1% over the prime rate, with a
$4,000 minimum monthly interest charge, 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. This agreement is
cancelable by the lender after giving a 90-day notice. The General Partner
believes amounts available under the line of credit are adequate for the
foreseeable future. The amount outstanding under this line of credit at
September 30, 2001 was $1,165,582.

At September 30, 2001, adequate cash is being generated to make projected
distributions and allow for reinvestment of a portion of the cash to fund
additional leases and notes. However, the Partnership has not yet achieved an
earnings level equivalent to its operating distributions to partners.
