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

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

In 1998, net cash used by operating activities totaled
$1,608,121. The Partnership paid management fees of $235,436
to the Managing General Partners and reimbursed related
parties for operating expenses of $1,242,610 in 1998. In
addition, $38,731 was paid to the Individual General Partners
as compensation for their services. Other operating expenses
of $196,818 were paid and interest income of $105,474 was
received.

In 1998, the Partnership funded equity investments of
$1,085,068 and issued notes receivables of $215,442 primarily
to portfolio companies in the medical/ biotechnology and
communications industries. Proceeds from sales of equity
investments were $612,545 and repayments of equity
investments and notes receivable provided cash of $204,848.

The Partnership declared a $2,370,130 distribution in the
fourth quarter of 1998, of which $2,000,000 was paid in the
fourth quarter of 1998 and $370,130 will be paid in 1999. In
February 1998, the Partnership paid $3,544,571 in
distributions which had been declared in 1997.

Cash and cash equivalents at December 31, 1998, were
$1,188,918. As of December 31, 1998, the Partnership was
committed to fund $180,056 in additional investments. Future
proceeds from investment sales and interest income on short-
term investments are expected to be adequate to fund
Partnership operations through the next twelve months.

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

1998 compared to 1997
- ---------------------

Net loss was $343,166 in 1998 compared to $12,128,444 in
1997. The decrease in net loss was substantially due to a
$16,622,168 increase in the change in net unrealized fair
value of equity investments and a $3,346,636 decrease in
realized losses from investment write-downs. The decrease
was partially offset by a $7,521,579 decrease in net realized
gain from sales of equity investments.

During 1998, the increase in fair value of $1,358,307 was
primarily attributable to an increase in a portfolio company
in the environmental industry, partially offset by a decrease
in portfolio companies in the computer systems and software
and medical/biotechnology industries. In 1997, the
$15,263,861 decrease in fair value of equity investments
included a $6,536,993 decrease attributable to sales of equity
investments, a $6,800,875 decrease attributable to a decline
in the publicly-traded market price of Thermatrix Inc., a
portfolio company in the environmental industry, and a
$1,608,431 decrease attributable to investment write-downs.

During 1998, the Partnership recorded realized losses from
investment write-downs of $422,261 attributable to equity
investments in ConjuChem, Inc. (formerly RedCell, Inc.) and
YES! Entertainment Corporation. During 1997, realized losses
from investment write-downs of $3,768,897 were mainly
attributable to equity investments in portfolio companies in
the computer systems and software and communications
industries.

In 1998, net realized gain from sales of equity investments
of $178,402 was mainly due to the receipt of proceeds
escrowed in the Quintar sale, partially offset by losses from
the sale of the Partnership's investment in NetChannel, Inc.
During 1997, the $7,699,981 realized gain from sales of
equity investments was primarily attributable to the sale and
liquidation of investments in Shaman Pharmaceuticals, Inc.,
Systemix, Inc., UTStarcom, Inc., Multiport Inc. and Quintar
Corporation.

Total operating expenses were $1,336,021 and $1,126,595 for
1998 and 1997, respectively. As disclosed in Note 2 to the
financial statements, the Managing General Partners
reevaluated allocations to the Partnership in 1998 and
determined that they had not fully recovered allocable
operating expenses, primarily salary, benefits, and
professional fees as permitted by the Partnership Agreement.
As a result, the Partnership was charged $193,391 of
additional operating expenses in 1998 of which $24,256 and
$169,135 related to 1997 and to prior years, respectively.
If the additional expense had been recorded in prior years,
total operating expenses would have been $1,142,630 and
$1,150,851 for 1998 and 1997, respectively.

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

1997 compared to 1996
- ---------------------

Net loss was $12,128,444 in 1997 compared to $2,031,279 in
1996. The increase in net loss was substantially due to a
$14,490,084 decrease in the change in net unrealized fair
value of equity investments and a $2,690,556 increase in
realized losses from investment write-downs. These decreases
were partially offset by a $6,710,947 increase in net
realized gain from sales of equity investments and a $269,700
increase in net realized gains from venture capital limited
partnership investments.

During 1997, the $15,263,861 decrease in fair value of equity
investments included a $6,536,993 decrease attributable to
sales of equity investments, a $6,800,875 decrease
attributable to a decline in the publicly-traded market price
of Thermatrix Inc., a portfolio company in the environmental
industry, and a $1,608,431 decrease attributable to
investment write-downs. During 1996, the decrease in fair
value of $773,777 was primarily attributable to the sales of
Shaman Pharmaceuticals, Inc., common stock as the gain was
realized. This decrease was partially offset by an increase
in portfolio companies in the environmental industries.

In 1997, the $7,699,981 realized gain from sales of equity
investments was primarily attributable to the sale and
liquidation of investments in Shaman Pharmaceuticals, Inc.,
Systemix, Inc., UTStarcom, Inc., Multiport Inc. and Quintar
Corporation. In 1996, net realized gain from sales of equity
investments of $989,034 was mainly due to the sale of Shaman
Pharmaceuticals, Inc., partially offset by losses from
Cardiometrics, Inc., Pinterra Corporation and Graham-Field
Health Products, Inc.

During 1997 and 1996, the Partnership recorded realized
losses from investment write-downs of $3,768,897 and
$1,078,341, respectively, primarily attributable to equity
investments in portfolio companies in the computer systems
and software and communications industries.

Total operating expenses were $1,126,595 and $1,065,940 in
1997 and 1996, respectively. The increase was primarily due
to higher investment operations and administrative and
investor services expenses as a result of increased overall
portfolio activities, partially offset by lower interest
expense. Included in 1997 operating expenses are the costs
of the Partnership's relocation of its administrative and
investor service operations to Santa Fe, New Mexico.

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 is reviewing public Year 2000 statements of
those suppliers and preparing questionnaires to be sent to
mission-critical vendors whose public statements were not
adequate for assessment. 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 failure to convert
will not have a material adverse effect on the Partnership.

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

Expenditures in 1998 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.

Item 11. EXECUTIVE COMPENSATION
- ------- ----------------------

management fees. The fees are designed to compensate the
Managing General Partners for General Partner Overhead
incurred in performing management duties for the Partnership
through December 31, 1998. General Partner Overhead (as
defined in the Partnership Agreement) includes the General
Partners' share of rent and utilities, and certain salaries
and benefits paid by the Managing General Partners in
performing their obligations to the Partnership. As
compensation for their services, the Individual General
Partners each receive $10,000 annually, plus $1,000 for each
attended meeting of the management committee and related
expenses. In 1998, $38,731 of such fees were paid.

Item 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND

Not applicable. No Limited Partner beneficially holds more
than 5% of the aggregate number of Units held by all Limited
Partners, and neither the Managing General Partners nor any
of their officers, directors or partners own any Units. The
three Individual General Partners each own 20 Units; on March
20, 1998, one of the three Individual General Partners
resigned his position and his Units were transferred to his
successor. The Management Committee controls the affairs of
the Partnership pursuant to the Partnership Agreement.

Item 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
- ------- ----------------------------------------------

The Registrant, or its investee companies, have engaged in no
transactions with the Managing General Partners or their
officers and partners other than as described above, in the
notes to the financial statements, or in the Partnership
Agreement.

INDEPENDENT AUDITORS' REPORT
----------------------------

The Partners
Technology Funding Venture Partners IV, An Aggressive Growth Fund,
L.P.:

We have audited the accompanying balance sheets of Technology
Funding Venture Partners IV, An Aggressive Growth Fund, L.P. (a
Delaware limited partnership) as of December 31, 1998 and 1997,
and the related statements of operations, partners' capital, and
cash flows for each of the years in the three-year period ended
December 31, 1998. 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. Our
procedures included confirmation of certain securities and loans
owned, by correspondence with the individual investee and
borrowing companies, and a physical examination of those
securities held by a safeguarding agent as of December 31, 1998
and 1997. 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
Technology Funding Venture Partners IV, An Aggressive Growth Fund,
L.P. as of December 31, 1998 and 1997, and the results of its
operations and its cash flows for each of the years in the three-
year period ended December 31, 1998, in conformity with generally
accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS
- -----------------------------

1. Summary of Significant Accounting Policies
------------------------------------------

Organization
- ------------

Technology Funding Venture Partners IV, An Aggressive Growth Fund,
L.P. (the "Partnership") is a limited partnership organized under
the laws of the State of Delaware on December 4, 1986. The purpose
of the Partnership is to make venture capital investments in new and
developing companies. The Partnership elected to be a business
development company under the Investment Company Act of 1940, as
amended (the "Act"), and operates as a nondiversified investment
company as that term is defined in the Act. The Managing General
Partners are Technology Funding Ltd. ("TFL") and Technology Funding
Inc. ("TFI"), a wholly owned subsidiary of TFL. There are generally
three Individual General Partners; effective March 20, 1998, an
Individual General partner resigned, and a successor was appointed.

The Partnership's registration statement was declared effective by
the Securities and Exchange Commission on November 14, 1988, and the
Partnership commenced selling units of limited partnership interests
("Units") on January 10, 1989.

On February 16, 1989, the minimum number of Units required to
commence Partnership operations (15,000) were sold. The offering
terminated with 400,000 Units sold on September 14, 1990. The
Partnership's term was extended for a two-year period to December
31, 1999 pursuant to unanimous approval by the Management Committee
on December 5, 1997. The Partnership Agreement provides that the
Partnership may be further extended for an additional two-year
period from such date if the Management Committee so determines or
unless sooner dissolved.

Preparation of Financial Statements and Use of Estimates
- --------------------------------------------------------

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from
those estimates. Estimates are used when accounting for
investments, change in unrealized fair value of investments,
liabilities and contingencies. Because of the inherent uncertainty
of valuation, the estimated fair value of investments may differ
significantly from the values that would have been used had a ready
market for investments existed, and the differences could be
material.

Investments
- -----------

Equity Investments
------------------

The Partnership's method of accounting for investments, in
accordance with generally accepted accounting principles, is the
fair value basis used for investment companies. The fair value of
Partnership equity investments is their initial cost basis with
changes as noted below:

The fair value for publicly traded equity investments (marketable
equity securities) is based upon the five-day-average closing sales
price or bid/ask price that is available on a national securities
exchange or over-the-counter market. Certain publicly traded equity
investments may not be marketable due to selling restrictions and
for those securities, an illiquidity discount of up to 33% is
applied when determining the fair value; the actual discount
percentage is based on the type and length of the restrictions.
Investments valued under this method were $2,967,543 and $2,414,032
at December 31, 1998 and 1997, respectively.

All investments which are not publicly traded are valued at fair
market value as determined by the Managing General Partners in the
absence of readily ascertainable market values. Equity investments
valued under this method were $12,679,770 and $11,819,969 at
December 31, 1998 and 1997, respectively. Generally, investments in
privately held companies are valued at original cost unless there is
clear evidence of a change in fair value, such as a recent round of
third-party financings or events that, in the opinion of the
Managing General Partners, indicate a change in value.

Convertible and subordinated notes receivable are stated at cost
plus accrued interest, which is equivalent to fair value, and are
included in equity investments as repayment of these notes generally
occurs through conversion into equity investments.

Venture capital limited partnership investments are initially
recorded at cost and are valued based on the fair value of the
underlying investments. Limited partnership distributions that are
a return of capital reduce the cost basis of the Partnership's
investment. Distributions from limited partnership cumulative
earnings are reflected as realized gains by the Partnership.

Where, in the opinion of the Managing General Partner, events
indicate that the fair value of equity and venture capital
investments and convertible and subordinated notes receivable may
not be recoverable, a write-down to estimated fair value is
recorded. Temporary changes in fair value result in increases or
decreases to the unrealized fair value of equity investments.
Adjustments to fair value basis are reflected as "Change in net
unrealized fair value of equity investments." In the case of an
other than temporary decline in value below cost basis, an
appropriate reduction in the cost basis is recognized as a realized
loss with the fair value being adjusted to match the new cost basis.
Cost basis adjustments are reflected as "Realized losses from
investment write-downs" or "Net realized loss from venture capital
limited partnership investments" on the Statements of Operations.

Sales of equity investments are recorded on the trade date. The
basis on which cost is determined in computing realized gains or
losses is specific identification.

Notes Receivable
----------------

The secured and unsecured notes receivable portfolio includes
accrued interest less the allowance for loan losses. The portfolio
approximates fair value through inclusion of an allowance for loan
losses. Allowance for loan losses is reviewed quarterly by the
Managing General Partners and is adjusted to a level deemed adequate
to cover possible losses inherent in notes and unfunded commitments.
Secured notes receivable are placed on nonaccrual status when, in
the opinion of the Managing General Partners, the future
collectibility of interest or principal is in doubt.

Cash and Cash Equivalents
- -------------------------

Cash and cash equivalents are principally comprised of cash invested
in demand accounts and money market instruments and are stated at
cost plus accrued interest. The Partnership considers all money
market and short-term investments with an original maturity of three
months or less to be cash equivalents.

Net Realized Income (Loss) Per Unit
- -----------------------------------

Net realized income (loss) per Unit is calculated by dividing the
number of Units outstanding of 400,000 as of December 31, 1998, 1997
and 1996 into the total net realized income (loss) allocated to the
Limited Partners. The Managing General Partners contributed an
amount equal to 0.1% of total Limited Partner capital contributions
and did not receive any Partnership Units.

Provision for Income Taxes
- --------------------------

No provision for income taxes has been made by the Partnership as
the Partnership is not directly subject to taxation. The partners
are to report their respective shares of Partnership income or loss
on their individual tax returns.

Since the accompanying financial statements are prepared using
generally accepted accounting principles which may not equate to tax
accounting, the Partnership's total tax basis in investments was
higher than the reported total cost basis of $12,750,763 by
$3,315,876 as of December 31, 1998.

2. Related Party Transactions
--------------------------

Related party costs are included in costs and expenses shown on the
Statements of Operations. Related party costs in 1998, 1997 and
1996 were as follows:


For the Years Ended December 31,
-------------------------------------
1998 1997 1996
------ ------ ------


Management fees $206,009 296,900 409,036
Individual General
Partners' compensation 38,731 46,042 47,730
Reimbursable operating
expenses:
Investment operations 300,503 316,342 238,851
Administrative and
investor services 614,557 367,404 297,381
Computer services 207,921 115,628 128,227



Effective February 1994, management fees are equal to one quarter of
one percent of the fair value of Partnership assets for each
quarter. Management fees compensate the Managing General Partners
solely for General Partner Overhead (as defined in the Partnership
Agreement) incurred in supervising the operation and management of
the Partnership and the Partnership's investments. Management fees
due to the Managing General Partners were $11,186 and $40,613 at
December 31, 1998 and 1997, respectively.

As compensation for their services, each of the Individual General
Partners receives $10,000 annually, plus $1,000 for each attended
meeting of the Management Committee and related expenses. The three
Individual General Partners each own 20 Units; on March 20, 1998,
one of the three Individual General Partners resigned his position
and his Units were transferred to his successor.

The Partnership reimburses the Managing General Partners for
operating expenses incurred in connection with the business of the
Partnership. Reimbursable operating expenses include expenses
(other than Organizational and Offering expenses and General Partner
Overhead) such as investment operations, administrative and investor
services and computer services. At December 31, 1998, there were
$40,957 of such reimbursable expenses due from related parties,
compared to $78,672 due to related parties at December 31, 1997.

The Managing General Partners allocate operating expenses incurred
in connection with the business of the Partnership based on employee
hours incurred. In 1998, operating cost allocations to the
Partnership were re-evaluated. The Managing General Partners
determined that they had not fully recovered allocable operating
expenses, primarily salary, benefits, and professional fees, as
permitted by the Partnership Agreement. As a result, the
Partnership was charged additional operating expenses of $193,391
consisting of $24,256, $36,058, and $133,077 for 1997, 1996, and
prior years, respectively. Had the additional expenses been
recorded in prior years, operating expenses would have been
$1,142,630, $1,150,851, and $1,101,998 for 1998, 1997, and 1996,
respectively.

In 1997, Multiport, Inc., which was wholly owned by the Partnership,
ceased operations and was liquidated, resulting in a cash
distribution to the Partnership of $1,929,078 and a realized gain of
$1,131,678.

Effective November 1, 1997, TFL assigned its California office lease
to Technology Funding Property Management LLC (TFPM), an entity that
is affiliated to the Managing General Partner. Under the terms of a
rent agreement, TFPM charges the Partnership for its share of office
rent and related overhead costs. These amounts are included in
administrative and investor service costs.

In September of 1996, the Partnership made a tax distribution of
57,917 Thermatrix Inc. common shares to the General Partners (based
on estimated annual taxable income); the shares had a fair value of
$316,227 resulting in a realized gain of $12,163 being recognized by
the Partnership.

Under the terms of a computer service agreement, Technology
Administrative Management, a division of TFL, charges the
Partnership for its share of computer support costs. These amounts
are included in computer services expenses.

Officers of the Managing General Partners occasionally receive stock
options as compensation for serving on the Boards of Directors of
portfolio companies. It is the Managing General Partners' policy
that all such compensation be transferred to the investing
partnerships. If the options are non-transferable, they are not
recorded as an asset of the Partnership. Any profit from the
exercise of such options will be transferred if and when the options
are exercised and the underlying stock is sold by the officers. At
December 31, 1998, the Partnership had an indirect interest in non-
transferable Physiometrix, Inc., Endocare, Inc., and UroGen Corp.
options at an exercise price higher than the current market value.
At December 31, 1998, the Partnership had an indirect interest in
non-transferable Thermatrix Inc. options with a fair market value of
$8,000.


3. Allocation of Profits and Losses
--------------------------------

Net realized profit and loss of the Partnership are allocated based
on the beginning-of-year partners' capital balances as follows:

(a) Profits:

(i) First, to those partners with deficit capital
account balances until such deficits have been
eliminated; then

(ii) Second, to the partners as necessary to offset the
net loss and sales commissions previously allocated
under (b)(ii) below; then

(iii)75% to the Limited Partners as a group in proportion
to the number of Units held, 5% to the Limited
Partners in proportion to the Unit Months of each
Limited Partner, and 20% to the Managing General
Partners. Unit months are the number of half months
a Unit would be outstanding if held from the date the
original holder of such Unit was deemed admitted into
the Partnership until the termination of the offering
of Units.

(b) Losses:

(i) First, to the partners as necessary to offset the net
profit previously allocated to the partners under
(a)(iii) above; then

(ii) 99% to the Limited Partners and 1% to the Managing
General Partners.

Losses allocable to Limited Partners in excess of their capital
account balances will be allocated to the Managing General Partners,
with net profit thereafter otherwise allocable to those Limited
Partners being allocated to the Managing General Partners to the
extent of such losses.

Losses from unaffiliated venture capital limited partnership
investments are allocated pursuant to section (b) above. Gains are
allocated first to offset previously allocated losses pursuant to
(b)(i) above, and then 99% to the Limited Partners and 1% to the
Managing General Partners.

9. Distributions

In 1998, the Managing General Partners declared a distribution for Unit
holders as of July 2, 1998 totaling $2,370,130 (payable to each partner
based on their proportionate share of partner capital including unrealized
gains and losses), of which $613,245 and $1,386,755 ($3.47 per unit) was
paid to the General Partners and Limited Partner, respectively, in 1998.
The remaining $370,130 ($0.93 per Unit) will be paid to the Limited
Partners in 1999.

In 1997, the Managing General Partners declared a distribution for Unit
holders as of September 30, 1977 totaling $4,000,000, of which $455,429 was
paid to the General Partners in 1997 and $3,544,571 ($8.86 per Unit) was
paid to the Limited Partners in 1998.

10. Commitments and Contingencies
-----------------------------

The Partnership is a party to financial instruments with off-balance-sheet
risk in the normal course of its business. Generally, these instruments
are commitments for future equity fundings, venture capital limited
partnership investments, equipment financing commitments, or accounts
receivable lines of credit that are outstanding but not currently fully
utilized. As they do not represent current outstanding balances, these
unfunded commitments are properly not recognized in the financial
statements. At December 31, 1998, unfunded investment commitments to
portfolio companies and venture capital limited partnerships totaled
$180,056.

The Partnership uses the same credit policies in making these commitments
and conditional obligations as it does for on-balance-sheet instruments.
Commitments to extend financing are agreements to lend to a company as long
as there are no violations of any conditions established in the contract.
The credit lines generally have fixed termination dates or other
termination clauses. Since many of the commitments are expected to expire
without being fully drawn upon, the total commitment amounts do not
necessarily represent future cash requirements.

In September 1995, the Partnership jointly guaranteed with two affiliated
partnerships a $2,000,000 line of credit between a financial institution
and a portfolio company in the computer systems and software industry of
which the Partnership's share was $500,000. In October 1996, the
$2,000,000 guarantee mentioned above was reduced to $1,000,000 as
Multiport, Inc., which was wholly owned by the Partnership, and an
affiliated partnership assumed $1,000,000 of the financial institution's
line of credit. The Partnership remained a joint guarantor of the
remaining $1,000,000. In November 1997, the portfolio company failed to
repay the line of credit and an affiliated partnership repaid the entire
obligation at no cost to the Partnership.
