                                     PART I


ITEM 1 - BUSINESS

Datronic Finance Income Fund I, L.P. (the "Partnership"), a Delaware Limited
Partnership, was formed on November 21, 1990. The Partnership offered Units of
Limited Partnership Interests (the "Units") during 1991 and early 1992 raising
$29,117,000 of limited partner funds.

As more fully described in Part II, Item 8, Notes 1 and 4, during the second
calendar quarter of 1992, it was learned that Edmund J. Lopinski, Jr., the
president, director and majority stockholder of Datronic Rental Corp. ("DRC"),
the then general partner, in conjunction with certain other parties, may have
diverted approximately $13.3 million of assets from the Datronic Partnerships
and Transamerica Equipment Leasing Income Fund, L.P.("TELIF") for his/their
direct or indirect benefit. During 1992, a class action lawsuit was filed and
subsequently certified on behalf of the limited partners in the Datronic
Partnerships against DRC, various officers of DRC and various other parties. On
March 4, 1993, a settlement (the "Settlement") was approved to resolve certain
portions of the suit to enable the operations of the Datronic Partnerships to
continue while permitting the ongoing pursuit of claims against alleged
wrongdoers. In connection with the Settlement, DRC was replaced by Lease
Resolution Corporation ("LRC") as the general partner of the Partnership.

The Partnership was formed to acquire finance leases for a variety of
low-technology, high-technology and other equipment. The cash generated during
the Partnership's Operating Phase from such investments was used to pay the
operating costs of the Partnership, make distributions to the limited partners
and the general partner (subject to certain limitations) and reinvest in
additional finance leases. During the Partnership's Liquidating Phase, which
began October 1, 1996, the cash generated from such investments is used to pay
the liquidating costs of the Partnership and make cash distributions to the
limited partners and the general partner (subject to certain limitations).
Concurrent with the commencement of the Liquidating Phase, the Partnership began
the orderly liquidation of the Partnership's assets.

A presentation of information about industry segments, geographic regions, raw
materials or seasonality is not applicable and would not be material to an
understanding of the Partnership's business taken as a whole. Since the
Partnership ceased investing in leases effective October 1995, a discussion of
sources and availability of leases, backlog and competition is not material to
an understanding of the Partnership's future activity.





                                       2
<PAGE>   3

The Partnership has no employees. LRC, the General Partner, employed 21 persons
at December 31, 1999 all of whom attend to the operations of the Datronic
Partnerships.

ITEM 2 - PROPERTIES

The Partnership's operations are located in leased premises of approximately
15,000 square feet in Schaumburg, Illinois.

LRC occupies approximately 3,800 square feet of office space in Schaumburg,
Illinois in a real estate property that is a Recovered Asset (see Part II, Item
8, Note 4) held for the benefit of the Datronic Partnerships.

ITEM 3 - LEGAL PROCEEDINGS

Reference is made to Part II, Item 8, Note 7 for a discussion of material legal
proceedings involving the Partnership.

ITEM 4 - SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of limited partners during the fourth
quarter of the fiscal year covered by this report through the solicitation of
proxies or otherwise.

ITEM 5 - MARKET FOR THE REGISTRANT'S LIMITED PARTNERSHIP UNITS AND RELATED
LIMITED PARTNER AND GENERAL PARTNER MATTERS

                               Market Information

The Units are not listed on any exchange or national market system, and there is
no established public trading market for the Units. To the best of LRC's
knowledge, no trading market exists for the Units that would jeopardize the
Partnership's status for federal income tax purposes.

As of March 13, 2000, the records of the Partnership show 1,533 record owners of
Units.

                                  Distributions

Reference is made to Part II, Item 8, Notes 6 and 9 for a discussion of Classes
of Limited Partners and distributions paid to limited partners and the general
partner.

ITEM 6 - SELECTED FINANCIAL DATA

The following table sets forth selected financial data as of December 31, 1999,
1998, 1997, 1996, and 1995 and for the five years then ended. The amounts
presented are aggregated for all Classes (A, B, and C) of Limited Partners,
unless otherwise noted. This information should be read in conjunction with the
financial statements included in Item 8 which also reflect amounts for each of
the classes of limited partners.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The following discussion and analysis presents information pertaining to the
Partnership's operating results and financial condition.

RESULTS OF OPERATIONS

The Partnership had a net loss of $367,000 in 1999 in the aggregate for all
classes of partners. This compares to aggregate net losses in 1998 and 1997 of
$253,000 and $381,000, respectively. 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 years ended December 31, 1999 include the following:

Lease income:
Since October 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 over the three years ended December 31, 1999. This trend will
continue as the Partnership liquidates its remaining leases.

Litigation proceeds:
Litigation proceeds represent the Partnership's proportionate share of
recoveries received during 1998 in connection with the resolution of litigation
against its former accountants. See Note 7 to the Partnership's financial
statements included in Item 8.

Recovery of Datronic Assets:
Recovery of Datronic Assets represents the Partnership's 10.2% share of
previously reserved cash balances held by a nominee company for the benefit of
the Datronic Partnerships. During 1998, potential claims against these funds
were resolved and a total of $750,000 was distributed proportionately to each of
the Datronic Partnerships. See Note 5 to the Partnership's financial statements
included in Item 8.

Interest income:
Interest income for all three years includes earnings on invested cash balances.
Interest income for 1999 was higher than 1998 and 1997 due to higher average
invested cash balances.

General Partner's expense reimbursement:
General Partner's expense reimbursement represents 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. See Note 9 to
the Partnership's financial statements included in Item 8.








                                       6
<PAGE>   7

Professional fees - litigation:
Professional fees - litigation represent fees paid in connection with the
Partnership's litigation which is described in Note 7 to the Partnership's
financial statements included in Item 8. The 1998 and 1997 amounts reflect fees
paid in connection with the litigation against the Partnership's former
accountants. Included in the 1998 amount are contingent fees paid or accrued
based on amounts recovered. The decrease in 1999 fees reflects the fact that all
major litigation was conducted during 1998 and only incidental matters remained
in 1999.

Professional fees - other:
Professional fees - other for the three years ended December 31, 1999 reflect a
decreasing level of professional services required as a result of the decrease
in the Partnership's lease portfolio and related activities.

Credit for lease loss:
These credits reflect recoveries of previously reserved balances.

Credit for loss on Diverted and other assets:
This credit represents the Partnership's share of any changes in the estimated
net realizable value of various assets held for the benefit of the Datronic
Partnerships. The credit in 1997 reflects a recovery of amounts previously
reserved for in 1995. Because of the fluctuating nature of real estate values
and the inherent difficulty of estimating the affects of future events, the
amounts ultimately realized from these assets could differ significantly from
their recorded amounts. See Note 4 to the Partnership's financial statements
included in Item 8.

LIQUIDITY AND CAPITAL RESOURCES

During 1999, Partnership assets continued to be converted to cash in order to
pay Partnership operating expenses and to provide for the ultimate liquidation
of the Partnership. During the year, Partnership cash and cash equivalents
decreased by $901,000 to $2,029,000 at December 31, 1999 from $2,930,000 at
December 31, 1998. This decrease is primarily due to a distribution paid to
Limited Partners of $978,000 (see below) and cash used in operations of $425,000
partially offset by cash receipts from collections on leases of $502,000.

The General Partner has declared an additional distribution totaling $1.26
million, payable to Limited Partners who are owners of record on March 31, 2000.
This distribution will be allocated to each Limited Partner based on their
proportionate share of total partners' capital attributable to their Class.








                                       7
<PAGE>   8
The Partnership's sources of future liquidity are expected to come from
cash-on-hand, cash receipts from leases owned by the Partnership and proceeds
from the sale of the remaining Diverted Assets (consisting primarily of an
office building in Schaumburg, Illinois). The lease portfolio is scheduled to be
fully liquidated by September 2000. The general partner expects that the
building will be sold during 2000 and the proceeds included in a subsequent
distribution to Limited Partners.

The Partnership's interest in the Schaumburg office building is carried on its
books at $402,000 (see Note 4 to the Partnership's financial statements included
in Item 8). At March 1993, the date LRC was appointed general partner, the
building was approximately 40% occupied. Since then, occupancy has increased to
more than 80% and base rental rates have increased by 75%. Accordingly, the
general partner believes that the value of the building has increased and that
this value will be realized when the building is sold. The amount to be realized
from the sale of the building, however, cannot be determined until it is sold.

After all assets are disposed of and the proceeds distributed to the Limited
Partners, the 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 2001.

IMPACT OF INFLATION AND CHANGING PRICES

Inflation is not expected to have any significant direct, determinable effect on
the Partnership's business or financial condition.

IMPACT OF YEAR 2000 ISSUE

The Year 2000 Issue relates to computer programs that use two digits rather than
four to define the year. This could cause date-sensitive software to recognize
the digits "00" as the year 1900 rather than 2000. During 1999, LRC completed
installation and implementation of new accounting and related software that is
fully capable of meeting the operating requirements of the Partnership in the
year 2000. The ongoing use of this software since December 31, 1999 has
confirmed that it is Year 2000 compliant. In addition, the Partnership's banks
have advised LRC that they are also Year 2000 compliant. The Partnership has
experienced no Year 2000 problems with the banks' computer systems

                          INDEPENDENT AUDITORS' REPORT



The Partners of Datronic
Finance Income Fund I, L.P.

We have audited the accompanying balance sheets in total for all classes of
limited partners of DATRONIC FINANCE INCOME FUND I, L.P. ("the Partnership") as
of December 31, 1999 and 1998 and the related statements of revenue and expenses
in total for all classes of limited partners, of changes in partners' equity and
of cash flows in total for all classes of limited partners for each of the three
years in the period ended December 31, 1999. 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.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Partnership as of December
31, 1999 and 1998, and the results of its operations in total for all classes of
limited partners and its cash flows in total for all classes of limited partners
for each of the three years in the period ended December 31, 1999 in conformity
with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the Partnership's
financial statements taken as a whole. As described in Note 2, the accounting
records of the Partnership are maintained to reflect the interests of each of
the classes of limited partners. Additional information consisting of the
balance sheets by class of limited partner as of December 31, 1999 and 1998, the
statements of revenue and expenses by class of limited partner and the
statements of cash flows by class of limited partner for the three years in the
period ended December 31, 1999 have been prepared by management solely for the
information of the limited partners and are not a required part of the financial
statements. This additional information has been subjected to the auditing

procedures applied in the audit of the Partnership's financial statements and,
in our opinion, has been allocated to the respective classes of limited partners
in accordance with the terms of the Amended Partnership Agreement described in
Note 9 and is fairly stated in all material respects in relation to the
Partnership's financial statements taken as a whole.

As explained more fully in Notes 1 and 4, the former President and Majority
Stockholder of Datronic Rental Corporation ("DRC"), the general partner of the
Partnership until March 4, 1993, and others are alleged to have diverted, for
their benefit, approximately $13 million from the Partnership and related
entities -- Datronic Equipment Income Fund XVI, XVII, XVIII, XIX, XX, L.P., and
Transamerica Equipment Leasing Income Fund, L.P. (collectively "the
Partnerships"). Substantially all of the assets known to have been improperly
acquired with the diverted funds have been recovered for the benefit of the
Partnerships.

                        NOTES TO THE FINANCIAL STATEMENTS
                        DECEMBER 31, 1999, 1998, AND 1997

NOTE 1 - ORGANIZATION:

Datronic Finance Income Fund I, L.P., a Delaware Limited Partnership (the
"Partnership"), was formed on November 21, 1990 for the purpose of acquiring and
leasing both high- and low-technology equipment. Through March 4, 1993, Datronic
Rental Corporation ("DRC") was the general partner of the Partnership and
Datronic Equipment Income Funds XVI, XVII, XVIII, XIX, and XX, (collectively,
the "Datronic Partnerships") and was co-general partner of Transamerica
Equipment Leasing Income Fund, L.P. ("TELIF").

In 1992, it was alleged that the chairman of DRC (who was also its president and
majority stockholder), in conjunction with various other parties, had
misappropriated and commingled $13.3 million of funds belonging to this and the
other Datronic Partnerships and TELIF. The Partnership's portion of these funds
was $1.9 million. In connection with a partial settlement of a class action
lawsuit arising from these allegations, Lease Resolution Corporation ("LRC")
replaced DRC as general partner of this and the other Datronic Partnerships on
March 4, 1993. LRC is a Delaware non-stock corporation formed for the sole
purpose of acting as general partner of the Datronic Partnerships.

On October 1, 1996, the Partnership began its Liquidating Phase under which it
has ceased investing in new leases and began the orderly liquidation of its
assets.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BASIS OF FINANCIAL STATEMENTS - The accounting records of the Partnership are
being maintained to reflect the interests of each of the classes of limited
partners (see Note 9). Each class of limited partner is not a separate legal
entity holding title to individual assets nor the obligor of individual
liabilities. Accordingly, assets allocated to a specific class of limited
partner are available to settle claims of the Partnership as a whole. Additional
information consisting of the balance sheets by class of limited partner as of
December 31, 1999 and 1998, the statements of revenue and expenses by class of
limited partner and the statements of cash flows by class of limited partner for
the three years ended December 31, 1999 have been prepared to present
allocations of the various categories of assets, liabilities, revenue, expenses
and cash flows of the Partnership to each of the classes of limited partners in
accordance with the Amended Partnership Agreement. In addition, the general
partner's equity has been allocated to each class of limited partner for
purposes of additional information because the equity attributable to the
general partner will be allocated to the limited

partners upon final dissolution of the Partnership. For purposes of this
additional information, the interests of the Class B and Class C Limited
Partners have been combined as "Continuing Limited Partners." At December 31,
1999, the amounts per Unit relating to these two classes are identical with the
exception that the per Unit value of Class C Limited Partners is $7.39 per Unit
higher than the Class B Limited Partners because, in accordance with the 1993
Settlement, Class Counsel fees and expenses related to the Settlement, net of
Datronic Assets, were not allocated to the Class C Limited Partners (see Note
5).

  CASH AND CASH EQUIVALENTS - Cash and cash equivalents consist principally of
overnight investments in high quality, short-term corporate demand notes
(commercial paper). Due to the nature of the Partnership's commercial paper
investments, Management does not believe there is any significant market risk
associated with such investments. Amounts due (to) from the general partner
(LRC) and other Datronic Partnerships are also included.

  NET INVESTMENT IN DIRECT FINANCING LEASES - Net investment in direct financing
leases consists of the present value of future minimum lease payments and
residuals under non-cancelable lease agreements. Residuals are valued at the
estimated fair market value of the underlying equipment at lease termination.

Leases are classified as non-performing when it is determined that the only
remaining course of collection is litigation. All balances relating to the lease
are netted together and no further income is accrued when a lease is classified
as non-performing.

Lease income includes interest earned on the present value of lease payments and
residuals (recognized over the term of the lease to yield a constant periodic
rate of return), interest collected on non-performing leases, late fees, and
other lease related items.

  ALLOWANCE FOR LEASE LOSSES - An allowance is recorded to reflect estimated
losses inherent in the existing portfolio of leases. Additions to the allowance
are made by means of a provision for lease losses, which is charged to expense.
Recoveries of amounts previously reserved are reflected as credits to the
provision for lease loss. The amounts shown in the accompanying Statements of
Revenue and Expenses reflect the net effect of provisions and recoveries.
Write-offs are deducted from the allowance.

 DUE (TO) FROM GENERAL PARTNER AND OTHER DATRONIC PARTNERSHIPS - In the ordinary
course of the Partnership's day-to-day operations, there are occasions when the
general partner and/or other Datronic Partnerships owe amounts to, and are owed
amounts from, the

Partnership. It is the Partnership's policy not to charge (credit) interest on
these payable (receivable) balances and to include them as cash equivalents.

  NET EARNINGS (LOSS) PER LIMITED PARTNERSHIP UNIT - Net earnings (loss) per
unit is based on net earnings (loss) after giving effect to a 1% allocation to
the general partner. The remaining 99% of net earnings (loss) for each of the
Liquidating and Continuing Limited Partners is divided by the weighted-average
number of units outstanding to arrive at net earnings (loss) per limited
partnership unit for each class of limited partner.

  USE OF ESTIMATES - In preparing financial statements in conformity with
generally accepted accounting principles, Management makes estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements, as well as the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

NOTE 3 - NET INVESTMENT IN DIRECT FINANCING LEASES:

The components of the net investment in direct financing leases at December 31,
1999 and 1998 are as follows:

The Partnership leased equipment with lease terms generally ranging from two to
five years. All remaining minimum payments are scheduled to be received on
performing leases during 2000.

NOTE 4 - DIVERTED AND OTHER ASSETS:

The $13.3 million of funds allegedly misappropriated from the Datronic
Partnerships and TELIF (collectively the "Partnerships") (see Note 1) were
commingled by the alleged wrongdoers with $10.3 million of funds and used to
acquire various assets. $20.7 million of such assets (collectively, "Diverted
and other assets") were subsequently recovered for the benefit of the
Partnerships and each Partnership was assigned an undivided pro rata interest in
them. These assets are held by a nominee company. The Partnership has a 14.4%
interest in these assets.

The Partnership's interest in these Diverted and other assets was recorded at
its proportionate share of their estimated net realizable value as of March
1993, the date LRC was appointed general partner. Provisions for losses were
recorded when it was determined that net realizable value of any of these assets
had declined below its March 1993 value. Gains are recognized only when
realized. Diverted and other assets recorded by the Partnership are reduced as
it receives cash distributions from the nominee company. Since 1993, LRC has
been liquidating these assets and distributing available funds to the
Partnerships. The remaining Diverted and other assets at December 31, 1999 had a
net book value of $4.3 million (Partnership's share $618,000). These assets
consisted of a seven-story office building in Schaumburg, Illinois ($2.8
million, Partnership's share $402,000) and $2.0 million of cash primarily
generated by the operations of the building (Partnership's share $287,000), less
a reserve for expenses for the liquidation of the nominee company ($500,000,
Partnership's share $72,000).

Due to increased occupancy and rental rates since March 1993, the general
partner believes that the fair market value of the office building exceeds its
remaining net book value. The amount to be realized from the sale of the
building, however, cannot be determined until it is sold, which is expected to
occur sometime during 2000.

During March 2000, $1.5 million of cash (Partnership's share $215,000) was
distributed from the nominee company to the Partnerships for distribution to the
Limited Partners. During 1998, $4.0 million of cash (Partnership's share
$577,000) was transferred from the nominee company. The Partnership's 1997
Statement of Revenue and Expenses includes a $101,000 realized gain on the
disposal of a real estate limited partnership interest that was part of Diverted
and other assets. This gain is included in "Credit for loss on Diverted and
other assets".

NOTE 5 - DATRONIC ASSETS:

At December 31, 1999, Datronic Assets consisted of the Partnership's 10.2%
interest in fully-reserved residual cash of $45,000 held by a nominee company
for the benefit of the Class A and B Limited Partners of the Datronic
Partnerships. The reserves are in anticipation of future costs or claims that
may be paid by the nominee.

Originally, Datronic Assets consisted of all of DRC's net assets which were
transferred to an LRC nominee company for the purpose of reimbursing the Class A
and B Limited Partners for legal fees paid in connection with the 1993
court-approved partial settlement of class action litigation (see Notes 1 and
2). Since then, all but $45,000 of the $1,732,000 (Partnership's share $177,000)
realized from the liquidation of the Datronic Assets has been distributed to the
Partnerships, including $750,000 (Partnership's share $76,500) during 1998. The
$76,500 realized by the Partnership during 1998 was previously fully-reserved
for claims that were ultimately resolved during 1998 and is shown in the
accompanying Statements of Revenue and Expenses as "Recovery of Datronic
Assets". The $76,500 and all previously realized Datronic Assets have been
allocated to the Class A and B Limited Partners.

Upon dissolution of the nominee company, any portion of the $45,000 that may
remain after payment of expenses will be distributed to the Partnerships in
proportion to each Partnership's interest in the Datronic Assets.

NOTE 6 - PARTNERS' EQUITY:

Distributions per Unit to the Limited Partners for 1999 and 1997 were:

                   Class A         Class B        Class C

        1997       $   -           $ 15.44        $ 12.21

The 1999 per unit amounts for each class include a $2.87 per unit distribution
resulting from litigation proceeds from settlements with the Partnerships'
former accountants (see Note 7).

No distributions were made in 1998.

The Partnership began its Liquidating Phase on October 1, 1996. Pursuant to the
Amended Partnership Agreement, all distributions made before that date were paid
on a per-unit basis and all subsequent distributions, with the exception of any
litigation proceeds, were based on the positive Capital Account balances of each
limited partner within each Class (see Note 9).

At December 31, 1999, 1998 and 1997, there were 7,699 Class A Units, 50,475
Class B Units, 60 Class C Units, and one General Partner Unit outstanding.

Funds raised by each Class and cumulative distributions to limited partners by
Class from the Partnership's formation through December 31, 1999 are:

NOTE 7 - LITIGATION:

CLAIMS AGAINST PROFESSIONALS

During 1992, various class action lawsuits and Partnership cross- claims were
filed against the Partnerships' former securities counsel (Siegan, Barbakoff,
Gomberg & Kane - "Siegan") alleging breach of fiduciary duty and the
Partnerships' former independent accountants (Weiss and Company and Price
Waterhouse) alleging professional negligence, breach of contract, and violations
of Section 11 of the Securities Act of 1933. As of December 31, 1996, the claims
against the Partnerships' former accountants remained open.

During 1998, the claims against the Partnerships' former accountants were
resolved. Weiss paid the Partnerships a total of $2.44 million in exchange for a
release from all Partnership claims and dismissal of the class claims against
it. After payment of $609,000 in contingent legal fees, $1.83 million of net
proceeds were distributed to the Partnerships (the Partnership's share was
$128,000).

Also during 1998, a jury verdict found Price Waterhouse negligent in the conduct
of their prior audits of the Partnerships and awarded damages of $739,300. After
payment of $185,000 of contingent legal fees, $556,000 of net proceeds were
distributed to the Partnerships in early 1999 (the Partnership's share was
$39,000).

The gross proceeds from Weiss and Price are included in the 1998 Statement of
Revenue and Expenses as "Litigation proceeds". The contingent legal fees are
included in the Statement of Revenue and Expenses as part of "Professional
fees-litigation".

OTHER CLAIMS

During 1994, a suit was filed on behalf of Datronic Partnerships XVII, XVIII,
and XIX arising from their 1990 purchase of a lease portfolio. The suit alleged
fraud and breach of contract against the original owner. During 1995, the U. S.
District court for the Northern District of Illinois dismissed the claim for
lack of jurisdiction. LRC, on behalf of the affected partnerships, re-filed the
complaint in the Circuit Court of Cook County, Illinois in the amount of $5.5
million, plus punitive damages and interest. During 1999, the Circuit Court
dismissed the complaint on the grounds that the re-filing constituted an
unallowable second re-filing of the complaint. LRC has appealed this ruling and
the appeal is pending in the Illinois Appellate Court.

The defendant filed a counterclaim against all of the Datronic Partnerships
seeking damages in connection with a 1992 transaction. The counterclaim seeks
damages for the defendant's fees, along with certain other damages. LRC believes
the counterclaim is without merit and is vigorously defending it.

NOTE 8 - PARTNERSHIP MANAGEMENT:

LRC directly manages the day-to-day operations of the Datronic Partnerships. The
cost of these services is allocated to each partnership based on the level of
services performed for each partnership. These expenses are reimbursed to LRC
pursuant to the terms of the Amended Partnership Agreement (see Note 9) and are
included in "General Partner's expense reimbursement".

General Partner's expense reimbursement for 1997, 1998 and 1999 also includes
consulting fees paid to two of the principals of New Era Funding, the
Partnership's management company prior to 1996. Each principal was paid $200,000
a year through March 31, 1999, when the

consulting agreements expired. These fees were allocated to each of the
Partnerships based on relative level of services performed for each.

NOTE 9 - PARTNERSHIP AGREEMENT:

As part of the 1993 Settlement each limited partner elected to become a Class A,
B or C Limited Partner.

Class A Limited Partners
This class elected to begin liquidating their interest in the Partnership as of
the Settlement date. Accordingly, each Class A Limited Partner is entitled to
receive cash distributions equal to their pro rata share of the net proceeds
from the disposition of assets owned by the Partnership on the Settlement Date,
plus their pro rata interest in the net proceeds from the disposition of
Datronic Assets, Diverted and other assets, and temporary investments. In
addition, Class A Limited Partners participated in the Class Action.

Class B Limited Partners
This class elected not to begin liquidation of their interest in the Partnership
as of the Settlement Date. Until the Liquidating Phase of the Partnership began
on October 1, 1996, each Class B Limited Partner received cash distributions
equal to 12.5% annually of their Adjusted Capital Contributions (as that term is
defined in the Amended Partnership Agreement). Available cash in excess of that
required to pay these distributions was invested in equipment and equipment
leases ("New Investments") and temporary investments on behalf of the Class B
Limited Partners. In addition, Class B Limited Partners participated in the
Class Action.

Class C Limited Partners
This class elected not to participate in the Class Action. Therefore, each Class
C Limited Partner: (i) preserved their individual claims against DRC and the
other defendants, (ii) did not participate in the Class Action, and (iii) did
not participate in the Settlement. In all other respects, including
distributions from the Partnership, Class C Limited Partners are the same as
Class B Limited Partners.

Concurrent with the beginning of the Liquidating Phase on October 1, 1996, the
Partnership ceased making New Investments and the General Partner (LRC) began
the orderly liquidation of Partnership assets. Pursuant to this, cash reserves
are to be maintained sufficient to satisfy all liabilities of the Partnership
and provide for future

contingencies. Cash available for distribution after satisfying such
requirements ("Cash Flow Available for Distribution") will be distributed to the
General and Limited Partners as described below.

During the Liquidating Phase, net Partnership proceeds from all sources, less
cash reserves needed to satisfy Partnership liabilities and provide for future
contingencies will be apportioned among the Class A, B and C Limited Partners,
each class as a group, in accordance with each class' interest in each type of
asset. Then, Liquidating Distributions will be made to the Limited Partners
within each class in accordance with the positive Capital Account balance of
each Limited Partner until all Limited Partners' Capital Account balances are
zero, and thereafter, pro rata based on the number of units outstanding.

The Amended Partnership Agreement provides for the General Partner (LRC) to
receive quarterly distributions equal to 1% of the Cash Flow Available for
Distribution. In addition, LRC receives reimbursement for expenses incurred in
excess of those covered by the 1% distribution. These expense reimbursements are
paid one quarter in advance and are adjusted based on LRC's actual expenses. LRC
allocates its expenses to each of the Datronic Partnerships based on its
activities performed for each Partnership. LRC is entitled to no other fees or
reimbursements from the Partnership.

The following summarizes the total of all payments to LRC during the three years
ended December 31, 1999:
