              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 2000


Note 1.  Management believes the accompanying unaudited condensed
         consolidated financial statements of Helm Capital Group, Inc. and
         subsidiaries (the Company) include all adjustments (consisting of only
         normal recurring accruals) required to present fairly the financial
         statements for the periods presented. The results of operations for any
         interim period are not necessarily indicative of the annual results of
         operations.

Note 2 - Earnings (Loss) Per Share

         The basic earnings (loss) per common share is computed by dividing the
         net income (loss) available to common shareholders by the weighted
         average number of common shares outstanding.

         Diluted earnings (loss) per common share is computed by dividing the
         net income (loss) available to common shareholders, adjusted on an as
         if converted basis, by the weighted average number of common shares
         outstanding plus potential dilutive securities.


The following illustrates income (loss) utilized in the computation of earnings
(loss) per share (in thousands):

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

RESULTS OF OPERATIONS

THREE MONTH PERIODS ENDED MARCH 31, 2000 AND 1999

         The net loss  of $45,000 for three months ended March 31, 2000
compared to a loss of $180,000 for the three months ended March 31, 1999. The
improvement was the result of $25,000 in seismic participation revenues
included in the 2000 period and a decrease of $96,000 in equity in losses of
affiliates. The 1999 period include $57,000 for equity losses in an affiliate
for which there is no remaining investment in 2000.


Impact of Inflation

         Inflation has not had a significant impact on the Company's operations.

Liquidity and Capital Resources

         Operating activities for the three months ended March 31, 2000 used
cash of $16,000. Collections on loans was $292,000 and $283,000 was used to
repay notes. Cash decreased by $7,000 for the period.

         Future liquidity sources for the Company will consist of revenues
generated from its financial service activities, reduction in selling, general
and administrative expenses, reimbursement of general and administrative
expenses from affiliates, and sales of investment securities. On a longer term
basis, the Company may be required to seek additional liquidity through debt or
equity offerings.


                                                                    Page 9 of 11

YEAR 2000 COMPLIANCE

         During 1999, the Company completed its Year 2000 ("Y2K") compliance
project to prepare its computer systems, applications and software products for
the year 2000 at an insignificant cost. Subsequent to December 31, 1999, the
Company has not experienced any Y2K disruptions, either internally or from
suppliers or other outside sources that had an adverse impact on the Company's
operations or financial condition. The Company has no reason to believe that Y2K
failures will materially affect it in the future. However, since it may take
several additional months before it is known whether the Company or its
suppliers, vendors or customers may have undergone Y2K problems, no assurances
can be given that the Company will not experience losses or disruption due to
Y2K computer-related problems. The Company will continue to monitor the
operation of its software products, computers and microprocessor-based devises
for any Y2K problems.

as other public documents of the Company contains forward-looking statements
which involve known and unknown risks, uncertainties and other factors which may

acts of God and natural disasters, as well as the demand for the Company's
services, or the ability of the Company to provide such services; (ii) the
insolvency or failure to pay its debts by a significant creditor of the Company
or its subsidiaries or affiliates, or the inadequacy or uncollectibility of any
collateral pledged to secure such creditor's debts to the Company or its
subsidiaries or affiliates; (iii) increased competition; (iv) changes in
customer preferences and the inability of the Company's subsidiaries of
affiliates to develop and introduce new services to accommodate these changes;
and (v) the maturing of debt at the Company, subsidiary or affiliate level and
the inability of the Company, the subsidiary or affiliate to raise capital to
repay or refinance such debt on favorable terms, or the insufficiency of
collateral pledged to secure any such debt.
