NOTES TO FINANCIAL STATEMENTS (unaudited)
----------------------------------------

1.     General
       -------

In the opinion of the Managing General Partners, the accompanying interim
financial statements reflect all adjustments necessary for a fair
presentation of the financial position, results of operations, and cash
flows for the interim periods presented.  These statements should be read
in conjunction with the Annual Report on Form 10-K for the year ended
December 31, 1998.  Allocation of income and loss to Limited and General
Partners is based on cumulative income and loss.  Adjustments, if any, are
reflected in the current quarter balances.

In April 1999, the Management Committee of the Partnership extended the
term of the Partnership to December 31, 2001.

2.     Financing of Partnership Operations
       -----------------------------------

The Managing General Partners expect cash received from the future
liquidation of Partnership investments and future short-term borrowings
will provide the necessary liquidity to fund Partnership operations.  The
Partnership may be dependent upon the financial support of the Managing
General Partners to fund operations if future proceeds are not received
timely.  The Managing General Partners have committed to support the
Partnership's working capital requirements through short-term advances as
necessary.

3.     Related Party Transactions

         Condition and Results of Operations

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

activities totaled $566,799.  The Partnership paid management fees of
$80,794 to the Managing General Partners and reimbursed related parties for
operating expenses of $266,755 in 1999.  In addition, $20,006 was paid to
the Individual General Partners as compensation for their services.  Other
operating expenses of $215,259 were paid and interest income of $16,015 was
received.

During the six months ended June 30, 1999, the Partnership funded equity
investments of $698,868 primarily to portfolio companies in the
communications, information technology and medical/biotechnology industries
and issued $183,333 in notes receivable to portfolio companies in the
environmental and medical/biotechnology industries.  Proceeds from the
sales of equity investments were $68,372 and repayments of notes receivable
were $198,844.  At June 30, 1999, the Partnership's unfunded commitments
totaled $641,700.

The Partnership has a borrowing account with a financial institution.  The
borrowing capacity of this account, which fluctuates based on collateral
value, was $341,995 at June 30, 1999 and there were no outstanding
borrowings.  As of August 12, 1999, the outstanding balance was $230,505.

operations through the next twelve months.

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

    Current quarter compared to corresponding quarter in the preceding year
    -----------------------------------------------------------------------

Net income was $1,043,196 for the quarter ended June 30, 1999, compared to
net income of $1,576,231 during the same period in 1998.  The change was
primarily due to a decrease of $419,040 in the net unrealized fair value of
equity investments and a $85,263 increase in operating expenses.

During the quarter ended June 30, 1999, the increase in equity investment
fair value of $1,352,222 was primarily attributable to increases in
portfolio companies in the communications and environmental industries,
partially offset by decreases in portfolio companies in the
medical/biotechnology industry.  During the same period in 1998, the
increase in fair value of equity investments of $1,771,262 was primarily
attributable to increases in portfolio companies in the environmental
industry, partially offset by decreases in the communications industry.

Total operating expenses were $327,469 and $242,206 for the quarters ended
June 30, 1999 and 1998, respectively.  The increase is primarily
attributable to increased investment monitoring activity , administrative
overhead and professional fees.

Given the inherent risk associated with the business of the Partnership,
the future performance of the portfolio company investments may
significantly impact future operations.

    Current six months compared to corresponding six months in the
    --------------------------------------------------------------
    preceding year
    --------------

Net income was $123,592 for the six months ended June 30, 1999, compared to
net income of $1,911,829 during the same period in 1998. The change was
primarily due to a decrease of $2,063,305 in the net unrealized fair value
of equity investments, partially offset by a $84,219 decrease in operating
expenses.

During the six months ended June 30, 1999, the increase in equity
investment fair value of $688,448 was mainly attributable to portfolio
companies in the communications and information technology industries,
partially offset by decreases in the microelectronics industry.  During the
same period in 1998, the increase of $2,751,753 was primarily attributable
to portfolio companies in the environmental industry.

Total operating expenses were $584,173 and $668,392 for the six months
ended June 30, 1999 and 1998, respectively.  The decrease is attributable
to decreased investment monitoring activities and computer expenses.


YEAR 2000
---------

Widespread use of computer programs that use two digits rather than four to
store, calculate, and display year values in dates may cause computer
systems to malfunction in the year 2000, resulting in significant business
delays and disruptions.

    The Partnership's State of Readiness
    ------------------------------------

Computer services are provided to the Partnership by its Managing General
Partner, Technology Funding Inc. ("TFI".)  For several years, TFI has
sought to use Year 2000 compliant storage formats and algorithms in its
internally-developed and maintained systems.  TFI has also completed
initial evaluations of computer systems, software, and embedded
technologies.  Those evaluations confirmed that certain components of its
network server hardware and operating systems, voice mail system, e-mail
system, and accounting software may have Year 2000 compliance issues.
These resources and several less-critical components of the systems
environment were all scheduled as part of normal maintenance and
replacement cycles to be replaced or upgraded as Year 2000 compatible
components became available from vendors during 1998 and 1999.  That
program remains on schedule to provide Year 2000 capable systems timely
without significant expenditures or disruption of Partnership operations.
However, the risk remains that TFI may not be able to verify whether Year
2000 compatibility claims by vendors are accurate, or whether changes
undertaken to achieve Year 2000 compatibility will create other undetected
problems in associated systems.  Therefore, TFI anticipates that Year 2000
compliance testing and maintenance of these systems will continue as needed
into the first quarter of 2000.

As part of Year 2000 evaluation, TFI has also assembled a database listing
its significant suppliers to assess the extent to which it needs to prepare
for any of those parties' potential failure to remediate their Year 2000
compliance issues.  TFI reviewed public Year 2000 statements of those
suppliers and sent questionnaires to mission-critical vendors whose public
statements were not adequate for assessment.  All mission-critical vendors
have responded that they expect to be Year 2000 compliant barring any
unforeseen circumstances.  TFI will continue to monitor its significant
suppliers as part of its Year 2000 evaluation.  However, there can be no
guarantee that the systems of other companies on which TFI relies will be
timely converted, or that failure to convert will not have a material
adverse effect on the Partnership and its operations.  TFI is also working
with the Partnership's portfolio companies to determine the extent to which
their operations are vulnerable to Year 2000 issues.  There can be no
guarantee that the systems of portfolio companies in which the Partnership
has invested will be timely converted, or that their failure to convert
will not have a material adverse effect on the Partnership.

    The Cost to Address Year 2000 Issues
    ------------------------------------

Expenditures in 1999 to date related to Year 2000 issues were not material
to the Partnership's financial statements.  TFI expects that additional
expenditures for Year 2000 compliance will not be material to the
Partnership.

    The Risks Associated with Year 2000 Issues
    ------------------------------------------

Any failure by the portfolio companies in which the Partnership has
invested, or by those portfolio companies' key suppliers or customers, to
anticipate and avoid Year 2000 related problems at reasonable cost could
have a material adverse effect on the value of and/or the timing of
realization of value from the Partnership's investments.  If Year 2000
compliance issues are not resolved by December 31, 1999, internal system
failures or miscalculations could cause a temporary inability to process
transactions, loss of ability to send or receive e-mail and voice mail
messages, or disruptions in other normal business activities.
Additionally, failure of third parties on whom TFI relies to remediate
their Year 2000 issues timely could result in disruptions in the
Partnership's relationship with its financial institutions, temporary
disruptions in processing transactions, unanticipated costs, and problems
related to the Partnership's daily operations.  While TFI continues to
address its internal Year 2000 issues, until TFI receives and evaluates
responses from a significant number of its suppliers, the overall risks
associated with the Year 2000 issue remain difficult to describe and
quantify.  There can be no guarantee that the Year 2000 issue will not have
a material adverse effect on the Partnership and its operations.

    TFI's Contingency Plan
    ----------------------

As part of its normal efforts to assure business continuation in the event
of natural disasters, systems failures, or other disruptions, TFI has
prepared contingency plans including an extensive Year 2000 contingency
plan.  Taken together with TFI's Year 2000 remediation plan, it identifies
potential points of failure, approaches to correcting known Year 2000
problems, dates by which the preferred corrections are anticipated to be
made and tested, and alternative approaches if the corrections are not
completed timely or are later found to be inadequate.  Although backup
systems and contingency approaches have been identified for most mission-
critical systems and vendor dependencies, there remain some systems for
which no good alternative exists, and there may be some problems that prove
more intractable than currently anticipated.
