Forward-Looking Statements
--------------------------

The Private Securities Litigation Reform Act of 1995 (the Act) provides a
safe harbor for forward-looking statements made by or on behalf of the
Partnership.  The Partnership and its representatives may from time to time
make written or oral statements that are "forward-looking," including
statements contained in this report and other filings with the Securities
and Exchange Commission, and reports to the Partnership's shareholders and
news releases.  All statements that express expectations, estimates,
forecasts and projections are forward-looking statements within the meaning
of the Act.  In addition, other written or oral statements, which
constitute forward-looking statements, may be made by or on behalf of the
Partnership.  Words such as "expects," "anticipates," "intends," "plans,"
"believes," "seeks," "estimates," "projects," "forecasts," "may," "should,"
variations of such words and similar expressions are intended to identify
such forward-looking statements.  These statements are not guarantees of
future performance and involve certain risks, uncertainties and
assumptions, which are difficult to predict.  Therefore, actual outcomes
and results may differ materially from what is expressed or forecasted in
or suggested by such forward-looking statements.  The Partnership
undertakes no obligation to update publicly any forward-looking statements,
whether as a result of new information, future events or otherwise.

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

1.     Interim Financial Statements
       ----------------------------

The accompanying unaudited financial statements included herein have been
prepared in accordance with the requirements of Form 10-Q and, therefore,
do not include all information and footnotes, which would be presented,
were such financial statements prepared in accordance with accounting
principles generally accepted in the United States of America.  These
statements should be read in conjunction with the Annual Report on Form 10-
K for the year ended December 31, 2005.  In the opinion of the Managing
General Partners, the accompanying interim financial statements reflect all
adjustments necessary for the fair presentation of the financial position,
results of operations, and cash flows for the interim periods presented.
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.  The results of operations for such interim
periods are not necessarily indicative of results of operations to be
expected for the full year or other interim periods.

2.	  Liquidation of the Partnership
  ------------------------------

In December of 2005, the Management Committee and the Managing General
Partners adopted a plan of liquidation and began the implementation
thereof.  As part of the plan of liquidation and in conjunction with the
anticipated dissolution and then liquidation of the Partnership, the
Independent General Partners also approved the retention of an independent
third party to assist in the sale of the Partnership's holdings.  On
February 15, 2006, the Independent General Partners approved a resolution
directing the Managing General Partners to notice a Special Meeting of the
Partnership at which meeting the Limited Partners would be asked to vote
upon a proposal to dissolve the Partnership prior to its scheduled
termination date of December 31, 2006, to place the Partnership's assets
and liabilities in a liquidating trust to be formed for that purpose, and
to withdraw the Partnership's election as a Business Development Company
under the 1940 Act.  Once the Liquidating Trust is formed and the
Partnership's assets and liabilities are transferred to the Liquidating
Trust, the Partnership shall be terminated for purposes of Delaware law and
the terms of the Liquidating Trust Agreement will govern disposition of
assets, proceeds and expenses.  Further, the Managing General Partners have
informed the Management Committee that they are only willing to continue
funding the Partnership's operating expenditures through the completion of
a prompt liquidation (estimated to be three to six months).  Any proceeds
from the liquidation of the assets of the Partnership will be paid first to
creditors of the Partnership including the Managing General Partners as
provided in Section 15.02 of the Limited Partnership Agreement.  The amount
owed to the Managing General Partners as creditors is expected to continue
to increase until proceeds from the sale of assets allow payments to all of
the creditors.  Based on changing market conditions and new information, it
is possible that the net proceeds from sale of the Partnership's assets
could be greater than or less than the aggregate estimated liquidation
values presented in the balance sheet.  If the aggregate proceeds are
ultimately less than the values presented, it is possible that the sale
proceeds will not be sufficient to meet the Partnership's obligations to
the creditors.  If that is the case, the limited partners may receive no
proceeds upon completion of the liquidation process.  Absent timely
liquidation events and cash proceeds to support the continuing operation of
the Partnership, the Managing General Partners may accelerate liquidation
efforts to minimize further increases in the obligations to creditors.  As
of March 31, 2006, substantially all of the publicly traded holdings had
been liquidated.  As of and since December 31, 2005, all of the
Partnership's holdings in privately held companies were valued at their
estimated liquidation value.  Upon dissolution, the Partnership, whether by
vote at the proposed special meeting or by operation of the Partnership
Agreement, will go into liquidation and pursuant to the Partnership
Agreement will accrue all estimated liquidation costs and any future
operating costs including administrative and investor services, computer
services, record retention costs, professional fees and estimated legal
costs of the Partnership through final termination, as provided for in the
Partnership Agreement.  Based on prior experience, management estimates it
will take no more than three to six months to liquidate all remaining
investments.  In the meantime, an Independent Third Party has been
assisting in the sale of Partnership holdings and will continue to solicit
interest in purchasing those holdings.  If no third party makes a bid
acceptable to the Liquidating Trustee (who shall be the Management
Committee, if still constituted, and otherwise shall be a Person proposed
and approved by a Majority in Interest of the Limited Partners), the
Managing General Partners may offer to acquire the remaining assets from
the Liquidating Trust for the fair value at the time of the transaction.
From December 31, 2005, through termination, the Partnership will continue
to incur costs similar to those experienced in prior years under normal
operating procedures except that there would be no charges related to
new investment operations, only follow-on investment operations.

3.     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.

The accompanying financial statements are prepared using accounting
principles generally accepted in the United States of America, which may
not equate to tax basis accounting.  The cost of investments on a tax basis
at March 31, 2006, and December 31, 2005, was $3,434,423 and $3,364,839,
respectively.  At March 31, 2006, and December 31, 2005, gross unrealized
depreciation on investments based on cost for federal income tax purposes
was as follows:

   Individual General Partners' compensation     10,000        17,000
   Reimbursable operating expenses              252,186       316,300

</TABLE>

Certain reimbursable expenses have been accrued based upon interim
estimates prepared by the Managing General Partners and are adjusted to
actual periodically. There were $0 and $830,861 due to related parties and
included in due from/to related parties, net at March 31, 2006, and
December 31, 2005, respectively, for such expenses.

Management fees due to the Managing General Partners and included in the
note payable to related parties, were $3,930 at March 31, 2006, and
included in due to related parties of $1,153 at December 31, 2005.


Effective March 31, 2006, the managing general partners converted the
inter-company payable of $1,134,928 to a note payable bearing an interest
rate of 5%. Principal and interest are due in full on December 31, 2006.

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.  Any such profit is allocated amongst the Partnership and
affiliated partnerships based upon their proportionate investment in the
portfolio company.  One of the Managing General Partners serves as interim
CEO and Chairman of the Board for Dakota Arms, Inc., a portfolio company.
The Managing General Partner does not receive any compensation for these
services.

Retention bonuses were offered to and accepted by key employees of the
Managing General Partners during 2002. The bonuses, incremented by annual
salary increases, will be paid to those individuals who are still full-time
employees of the Managing General Partners in April 2007.  The expense for
the bonus is recognized ratably over the beneficial period, October 2002 to
April 2007.  As of March 31, 2006, the Partnership has recognized expense
of $130,150.  Upon the resignation of personnel, no adjustment to the
retention bonus amount previously paid by the Partnership to the Managing
General Partners shall occur until a replacement person is hired.

5.     Equity Investments
       ------------------

All investments are valued at liquidation value as determined in good faith
by the Managing General Partners and in conjunction with Note 1 of the Form
10-K for the year ended December 31, 2005.

Restricted Securities
---------------------

At March 31, 2006, and December 31, 2005, restricted securities had
aggregate costs of $3,681,207 and $3,615,689 respectively, and aggregate
fair values of $1,057,504 and $1,044,399 respectively, representing 436.6
percent of the net assets of the Partnership as of December 31, 2005.  The
percentage is not applicable as of March 31, 2006 due to negative net
assets.

Significant purchases, sales and write-offs of equity investments during
the quarter ended March 31, 2006, are as follows:

Dakota Holdings, Inc.
----------------------

During the first quarter of 2006, the partnership issued an additional
$64,692 on the company's bridge loan financing and accrued interest of
$826.

Other Equity Investments
------------------------

Other significant changes reflected in the Statements of Investments relate
to market value fluctuations for publicly traded portfolio companies or
changes in the fair value of private companies as determined in accordance
with the policy described in Note 1 to the financial statements included in
the Partnership's December 31, 2005, Form 10-K.

6.     Cash and Cash Equivalents
       -------------------------

Cash and cash equivalents at March 31, 2006, and December 31, 2005,
consisted of demand accounts totaling $2,795.

7.     Commitments and Contingencies
       -----------------------------

From time to time, the Partnership is subject to routine litigation
incidental to the business of the Partnership.  Although there can be no
assurances as to the ultimate disposition of these matters, it is the
opinion of the Managing General Partners, based upon the information
available at this time and advice from legal counsel, that the expected
outcome of these matters, individually or in the aggregate, will not have a
material adverse effect on the results of operations and financial
condition of the Partnership.

</TABLE>

Pursuant to the Partnership Agreement, net profit shall be allocated first
to those Partners with deficit capital account balances until such deficits
have been eliminated. The net asset values shown above assume the
Partnership is in liquidation.  Per the terms of the limited partnership
agreement, subsequent to final liquidation of all partnership assets, the
General Partners would be required to contribute capital equal to the
amount of the General Partners' deficit capital account, if applicable.

Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations

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

The Partnership operates as a business development company under the
Investment Company Act of 1940 and makes venture capital investments in new
and developing companies.  As of and since December 31, 2005, the
Partnership is in liquidation and will not continue as a going concern.
The accompanying financial statements are shown on the liquidation basis,
and all amounts have been presented at their estimated liquidation value,
which management believes approximates its historical basis of accounting
and as a result, no specific adjustments have been made to the amounts
presented or to the labeling of the statements to reflect liquidation
accounting.  There is no ready market for many of the Partnership's
investments.  It is possible that some of its venture capital investments
may be a complete loss or may be unprofitable and that others will appear
likely to become successful, but may never realize their potential.  The
valuation of the Partnership's investments in securities for which there
are no available market quotes is subject to the estimate of the Managing
General Partners in accordance with the valuation guidance described in
Note 1 to the financial statements included in the Partnership's Form 10-K
for the year ended December 31, 2005.  In the absence of readily obtainable
market values, the estimated liquidation value of the Partnership's
investments may differ significantly from the values that would have been
used had a ready market existed.

During the three months ended March 31, 2006, net cash used by operating
activities totaled $0.  The Partnership paid management fees of $0 to the
Managing General Partners and reimbursed related parties for operating
expenses of $0.  In addition, $0 was paid to the Individual General
Partners as compensation for their services.  The Partnership paid other
investment expenses of $0, and $0 was paid in interest on short-term
borrowings. Interest income of $0 was received.

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

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

Net decrease in partners' capital resulting from operations was $316,550
for the three months ended March 31, 2006, compared to a net decrease in
partners' capital resulting from operations of $615,787 for the same period
in 2005.

Net unrealized depreciation on equity investments was $2,623,703 at March
31, 2006, compared to net unrealized depreciation of $2,571,290 at December
31, 2005.  During the quarter ended March 31, 2006, the Partnership
recorded an increase in net unrealized depreciation on equity investments
of $52,413, compared to an increase in net unrealized depreciation of
$343,606 during the same period in 2005.  The change in 2006 and 2005 was
due to decreases in management's valuation of private portfolio companies
in the retail/consumer products industry.

During the quarter ended March 31, 2006 and 2005, there were no realized
gains from venture capital limited partnership investments.

Total investment expenses were $264,963 and $344,154 for the quarters ended
March 31, 2006 and 2005, respectively. The decrease was due to decreased
activity in investment operations, administrative, and investor services,
professional fees, and computer services.

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