ambulatory cardiac monitoring, EKG telemetry, pulmonary function, EKG and
ambulatory blood pressure systems operate independently or in unison on an IBM

The accompanying condensed financial statements have been prepared by the
Company without audit. In the opinion of management, all adjustments (which
include only normal recurring adjustments) necessary to present fairly the
financial position, results of operations, and cash flows have been made.

Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted. These condensed financial statements should be
read in conjunction with the financial statements and notes thereto included in
the Company's Form 10-KSB for the year ended May 31, 1997.

The results of operations for the three months and nine months ended February
28, 1998, are not necessarily indicative of the operating results for the full
year.

NOTE 3. LITIGATION

In December 1997, the Company entered into a settlement agreement with a former
vendor to reduce a previously recorded jury award by $150,000. The agreement
calls for annual payments of $25,000 per year through December 2002 with an
additional $25,000 due December 1999. In the event the Company defaults on any
of the annual payments, the full judgment, less any amounts paid under the
settlement agreement, will be reinstated.

MANAGEMENT'S DISCUSSION AND ANALYSIS

RESULTS OF OPERATIONS

The Company's sales were $435,000 and $1,548,000 for the third quarter and nine
months ended February 28, 1998, respectively, compared to $746,000 and
$1,924,000 for the third quarter and nine months ended February 28, 1997. In the
third quarter the Company experienced decreased sales in the International
market of approximately $200,000 and in the US of approximately $100,000. These
decreases primarily account for the decrease in sales for the nine months ended
February 28, 1998. Cost of goods sold as a percentage of sales was 58% for the
third quarter and 51% for the nine months ended February 28, 1998. This is up
from 52% for the third quarter and 48% for the nine months ended February 28,
1997. As reported in previous quarters, the Company continues to experience
strong competitive pressures, especially in the international market caused
primarily by health care reforms. These pressures are negatively affecting both
sales and gross margins. In addition, international sales have been affected by
the Asian economic crisis.

Research, development and engineering expenditures decreased approximately
$28,000 for the third quarter and $5,000 for the nine months ended February 28,
1998 compared to the previous year. The decrease in the third quarter is due to
decreased number of personnel. Year to date, these decreases were offset by
increased expenditures in new product development and enhancements on current
product lines.

Sales and marketing expenses decreased $54,000 for the third quarter and
increased $28,000 for the nine months ended February 28, 1998 from the prior
year. The decrease in the third quarter was due to decreased commissions on
lower US and international sales. Year to date, these decreases were offset by
increased personnel in the first two quarters of 1998. These positions were
eliminated in the second quarter of 1998 when sales levels did not reach
expected levels.

General and administrative costs decreased $27,000 for the third quarter and
$46,000 for the nine months ended February 28, 1998 compared to the prior year.
These decreases are due to decreases in legal costs and recovery on receivables
that were previously charged off.

In December 1997, the Company entered into a settlement agreement with a former
vendor to reduce a previously recorded jury award by $150,000. The agreement
calls for annual payments of $25,000 per year through December 2002 with an
additional $25,000 due December 1999. In the event the Company defaults on any
of the annual payments, the full judgment, less any amounts paid under the
settlement agreement, will be reinstated.

LIQUIDITY AND CAPITAL RESOURCES

For the nine month period ending February 28, 1998 cash provided by operations
totaled $39,000 The net loss of $41,000 and increase in accrued expenses of
$199,000 were offset by a decrease in receivables of $134,000.

At February 28, 1998 the Company had working capital of $370,000. In March 1998,
the Company was notified that the bank line of credit in the amount of $25,000
was no longer available. There was no outstanding balance on the line. The
Company is making every effort to increase sales, decrease operating expenses
and manage assets to maximize cash flows. If these efforts are unsuccessful,
cash flows from operations may not be sufficient to fund operations and the
Company may be required to seek additional capital through equity offerings or
other financing sources.

On March 19, 1998, the Company entered into a letter of intent, subject to
