                         NOTES TO FINANCIAL STATEMENTS
                         -----------------------------
                               SEPTEMBER 30, 1999

                                  (Unaudited)

NOTE 1 - ORGANIZATION:
----------------------

Datronic Equipment Income Fund XIX, L.P., a Delaware Limited Partnership (the
"Partnership"), was formed on December 22, 1989 for the purpose of acquiring and
leasing both high-and low-technology equipment. See Notes 5, 8, and 10 to the
Partnership's financial statements included in the 1998 Form 10-K for a
discussion of the alleged diversion of Partnership assets in 1991 and 1992 and
the subsequent litigation and settlement, change in general partner, new classes
of limited partners established and amendments to the Partnership Agreement
which occurred.

NOTE 2 - BASIS OF FINANCIAL STATEMENTS:
---------------------------------------

The accompanying financial statements should be read in conjunction with the
Partnership's financial statements included in the 1998 Form 10-K. The financial
information furnished herein is unaudited but in the opinion of Management
includes all adjustments necessary (all of which are normal recurring
adjustments) for a fair presentation of financial condition and results of
operations. See Note 2 to the Partnership's financial statements included in the
1998 Form 10-K.

NOTE 3 - LIMITED PARTNERSHIP DISTRIBUTIONS:
-------------------------------------------

In early April 1999, the Partnership made a cash distribution to Limited
Partners who were owners of record on December 31, 1998. This distribution
consisted of two components: (i) the net proceeds from the Price Waterhouse and
Weiss & Company legal actions ($97,000 and $476,000 for Liquidating and
Continuing Limited Partners, respectively), and (ii) residual cash resulting
from the net cash flows of the Partnership ($962,000 and $1,093,000 for
Liquidating and Continuing Limited Partners, respectively). The portion of the
distribution attributable to legal action proceeds was allocated to each Limited
Partner based on the number of units held at the rate of $2.87 per unit. See
Note 8 to the Partnership's financial statements included in the 1998 Form 10-K.
Pursuant to the Partnership Agreement, residual cash was allocated to each
Limited Partner based on their proportionate share of total partners' capital
attributable to their Class.

PART I

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

The following discussion and analysis of liquidity and capital resources covers
material changes in the Partnership's financial condition from December 31, 1998
through September 30, 1999. The discussion and analysis of results of operations
is for the three and nine month periods ended September 30, 1999 as compared to
the corresponding periods in 1998. Any capitalized term not defined herein has
been defined or discussed in the Partnership's 1998 Form 10-K.

Liquidity and Capital Resources
-------------------------------

During the nine months ended September 30, 1999, Partnership assets continued to
be converted to cash in order to pay Partnership operating expenses and provide
for the ultimate liquidation of the Partnership. During this period, the
Partnership's cash and cash equivalents decreased by $2,253,000 to $3,712,000 at
September 30, 1999 from $5,966,000 at December 31, 1998. This decrease is
primarily due to distributions paid to Limited Partners of $2,628,000 (see
below) and by cash used in operations of $518,000, partially offset by cash
receipts from collections on leases of $885,000 and from commercial lease paper
of $8,000.

In early April 1999, the Partnership made a cash distribution to Limited
Partners who were owners of record on December 31, 1998. This distribution
consisted of two components: (i) the net proceeds from the Price Waterhouse and
Weiss & Company legal actions ($97,000 and $476,000 for Liquidating and
Continuing Limited Partners respectively), and (ii) residual cash resulting from
the net cash flows of the Partnership ($962,000 and $1,093,000 for Liquidating
and Continuing Limited Partners respectively). The portion of the distribution
attributable to legal action proceeds was allocated to each Limited Partner
based on the number of units held at the rate of $2.87 per unit. See Note 8 to
the Partnership's financial statements included in the 1998 Form 10-K. Pursuant
to the Partnership Agreement, residual cash was allocated to each Limited
Partner based on their proportionate share of total partners' capital
attributable to their Class.

The Partnership's sources of future liquidity are expected to come from
cash-on-hand, cash receipts from leases owned by the Partnership and the
disposition of the remaining Diverted Assets (consisting primarily of an office
building in Schaumburg, Illinois). The lease portfolio is scheduled to be fully
liquidated by December 2000. The general partner expects that the building will
be sold sometime during 2000. The proceeds will be included in the next
distribution to the Limited Partners sometime during 2000. After all assets are
disposed of and the proceeds distributed to the Limited Partners, the

                                       13


<PAGE>   14




Partnership will be required to file final reports with the Securities and
Exchange Commission and the Internal Revenue Service. The general partner
expects this to occur sometime during the year 2001.

Results of Operations
---------------------

The Partnership had net losses of $150,000 and $330,000 for the three and nine
months ended September 30, 1999 in the aggregate for all classes of partners.
This compares to aggregate net losses of $180,000 and $1,034,000 for the three
and nine months ended September 30, 1998. Differences in operating results
between Liquidating and Continuing Limited Partners are attributable to lease
income and expenses associated with new lease investments made since the March
4, 1993 Settlement. Liquidating Limited Partners do not participate in these
post Settlement activities. Significant factors affecting overall operating
results for the three and nine month periods ended September 30, 1999 and 1998
include the following:

Lease income:
Since August 1996, the Partnership has been in its Liquidating Phase which
prohibits investing in any new leases. Accordingly, the lease portfolio has
continued to decrease as collections are made, resulting in a continued decline
in lease income. This trend will continue as the Partnership liquidates its
remaining leases.

Interest income:
Interest income includes earnings on invested cash balances. Interest income for
1999 was higher than 1998 because of higher average invested cash balances.

General Partner's expense reimbursement:
General Partner's expense reimbursement includes payments to LRC for expenses it
incurred as general partner. These expenses include expenses incurred by LRC in
its management of the day-to-day operations of the Partnership.

Professional fees:
Professional fees for the three and nine months ended September 30, 1999 reflect
a decreasing level of professional services required as a result of the decrease
in the Partnership's lease portfolio and related activities. Included in the
1998 amount are fees paid in connection with the litigation against the
Partnership's former accountants.

Credits for lease losses and commercial lease paper:
These credits reflect recoveries of previously reserved amounts.
