                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)


1. BASIS OF PRESENTATION

The interim condensed financial statements included herein have been prepared by
the Company without audit pursuant to the rules and regulations of the
Securities and Exchange Commission (the "SEC"). Certain information and footnote
disclosures, normally included in the financial statements prepared in
accordance with generally accepted accounting principles, have been condensed or
omitted pursuant to such SEC rules and regulations; nevertheless, the management
of the Company believes that the disclosures herein are adequate to make the
information presented not misleading. These condensed financial statements
should be read in conjunction with the financial statements and notes thereto
included in the Company's Form 10-K/A for the year ended December 31, 1996 and
filed with the SEC. In the opinion of management, the condensed financial
statements included herein reflect all normal, recurring adjustments necessary
to present fairly the financial position of the Company as of March 31, 1997,
and the results of its operations and its cash flows for the three-month periods
ended March 31, 1996 and 1997. The results of operations for the interim periods
are not necessarily indicative of the results of operations for the full year.

2. STOCKHOLDERS' EQUITY AND EARNINGS PER SHARE

Net income per share is computed by dividing net income by the weighted average
number of common and common equivalent shares outstanding. For the three-month
periods ended March 31, 1996 and 1997 weighted average common and common
equivalent shares include common shares and stock options using the treasury
stock method. For the three-month period ended March 31, 1997, the adjusted
weighted average shares were equal to the basic weighted average shares due to
the anti-dilutive effect the conversion of options would have given the
Company's net loss for the period.

As of March 31, 1997 54,000 options were available for grant under the Director
Plan and no options were exercisable.

The Company has reserved an aggregate of 150,000 shares of Common Stock for
issuance under its 1996 Employee Stock Purchase Plan (the "ESPP"). The ESPP was
adopted by the Board of Directors in January 1996 and approved by the Company's
stockholders prior to the consummation of the Company's initial public offering
in February 1996. The ESPP is intended to qualify under Section 423 of the
Internal Revenue Code of 1986, as amended, and permits eligible employees of the
Company to purchase Common Stock through payroll deductions of up to 10% of
their compensation provided that no employee may purchase more than $25,000
worth of stock in any calendar year. The ESPP was implemented by an offering
period commencing on February 14, 1996 and ending on the last business day in
the period ending October 31, 1996. Each subsequent offering period (an
"Offering Period") will commence on the day following the end of the prior
Offering Period and will have a duration of six months. The price of Common
Stock purchased under the ESPP will be 85% of the lower of the fair market value
of the Common Stock on the first or last day of each offering period. The ESPP
will expire in the year 2006. In the year ended December 31, 1996 the Company
issued 32,815 shares of Common Stock under the ESPP for $153,410. At March 31,
1997, $101,901 had been withheld from employee earnings for stock purchases
under the ESPP.

New Accounting Pronouncement--In March 1997 the Financial Accounting Standards
Board issued Statement of Financial Accounting Standards No. 128, `Earnings Per
Share'. This new standard requires dual presentation of basic and diluted
earnings per share (EPS) on the face of the earnings statement and requires a
reconciliation of the numerators and denominators of basic and diluted EPS
calculations. This statement will be effective for the Company's 1997 fiscal
year. The Company's current EPS calculation conforms to basic EPS. Diluted EPS
will not be materially different from basic EPS since potential common shares in
the form of stock options are not materially dilutive.

GENERAL

     The Company provides facility-wide computer networks that acquire,
interpret and distribute real-time patient monitoring information. The Company's
networks acquire physiologic data generated by proprietary ambulatory ECG
monitors and other manufacturers' bedside equipment located throughout a
healthcare facility. The Company's products are sold directly to acute care
hospitals and integrated healthcare delivery networks ("IHDNs") and on an OEM
basis to patient monitoring equipment manufacturers.

     During the quarter ended March 31, 1997 direct sales of the Company's
facility-wide computer networks of $1,785,386 were 39.7% lower than the
$2,959,973 achieved in the same quarter in 1996. The Company believes that the
reduction in sales resulted from a mid-1996 restructuring of the sales force and
implementation of a new selling method focused on quantifying the financial
benefits and re-engineering opportunities enabled by its facility-wide network.
These changes shifted the Company's sales strategy from a clinical to a
financial and information systems focus. This new strategy lengthened the sales
cycle and disrupted focus on the Company's selling its core competency in
clinical applications. Although direct sales of facility-wide networks in the
quarter ended March 31, 1997 were 33.5% higher than the preceding quarter ended
December 31, 1996, and the Company believes that sales force productivity will
continue to increase in 1997, there can be no assurance that the Company's sales
efforts will result in sequentially increasing or historical sales levels in
future periods.

     Revenues from sales of facility-wide networks are recognized upon shipment.
The sales cycle for facility-wide networks has typically been from nine to 18
months. The Company has experienced seasonal variations in sales of its
facility-wide networks, with sales in the first quarter typically lower than the
preceding fourth quarter's sales due to customer budget cycles and sales
remaining relatively flat during the third quarter. Furthermore, a large
percentage of a particular quarter's shipments of facility-wide networks has
historically been booked in the last weeks of the quarter.

     Revenues from sales of departmental products are recognized upon shipment.
The selling cycle for departmental products varies depending upon product mix
and the extent to which the Company develops customized operating software for a
particular OEM customer. In addition, the Company has experienced seasonal
variations in sales of its departmental products, with third quarter sales of
departmental products generally being lower than other quarters.

     The Company's products are generally shipped as orders are received and,
accordingly, the Company typically operates with limited backlog. As a result,
sales in any quarter are dependent on orders booked and shipped in that quarter.

     To date the Company has not capitalized software development expenses.
However, the development of new products or the enhancement of existing products
may require capitalization of such expenses in the future.

RESULTS OF OPERATIONS - THREE MONTHS ENDED MARCH 31, 1997 AND MARCH 31, 1996

Total Revenues. Total revenues consist of revenue from sales of facility-wide
networks and departmental products, together with fees for installation and
servicing of products. Total revenues for the first quarter were $3,973,364,
compared to $5,969,107 achieved in the same period in 1996 and $3,496,151 in the
fourth quarter of 1996. Revenues in the first quarter of 1997 were 33.4% lower
than the same period in 1996, reflecting a 39.7% decrease in the Company's sales
of facility-wide network systems and a 27.3% decrease in departmental products
from the comparable period a year ago. When compared to the fourth quarter of
1996, total revenues were up 13.6%, with facility-wide sales increasing 33.5%
over the fourth quarter of 1996 and departmental sales up 1.4% from the fourth
quarter of 1996. Facility-wide network sales represented 44.9% of the revenues
in the quarter ended March 31, 1997 compared to 49.6% for the same quarter a
year ago.

Gross Profit. Cost of revenues sold generally includes material, direct labor,
overhead and, for facility-wide networks, installation expenses. Gross profits
in the first quarter of 1997 were 42.6% of revenues as compared to 57.6% in the
first quarter of 1996. Total gross profit decreased 50.8% to $1,690,762 in the
first quarter of 1997 from $3,436,897 in the first quarter of 1996, on a 33.4%
decrease in revenues. The decrease in gross profit in the first quarter of 1997
as compared to the first quarter of 1996 was due to lower revenues with fixed
costs in overhead constituting a higher percentage of revenues. In the first
quarter of 1997, the Company accrued one-time costs of $155,000 associated with
the termination of the Vice President of Operations; without this charge, gross
profit would have been 3.9% higher, or 46.5% of revenues.

Sales and Marketing Expenses. Sales and marketing expenses include payroll,
commissions and related costs attributable to direct and OEM sales and marketing
personnel, travel and entertainment expenses, and other promotional expenses.
Sales and marketing expenses of $2,361,460 were 59.4% of revenues in the first
quarter of 1997 compared to $2,106,225 in the 



                                       8

first quarter of 1996, or 35.3% of revenues in the comparable period a year ago.
The $255,235 increase in sales and marketing expenses in the first quarter of
1997 as compared to the first quarter of 1996 was primarily attributable to an
increase in sales and marketing payroll and related support and travel and
entertainment expenses associated with the increased number of sales and
marketing personnel.

Research and Development Expenses. Research and development expenses include
payroll and related costs attributable to research and development personnel,
prototyping expenses and other costs. Research and development expenses of
$1,069,357 were 26.9% of revenues in the first quarter of 1997 as compared to
$918,348 or 15.4% of revenues for the first quarter of 1996. The $151,014
increase in the first quarter of 1997 as compared to the first quarter of 1996
was due primarily to an increase in the number of research and development
personnel and an increasing number of projects.

General and Administrative Expenses. General and administrative expense includes
accounting, finance, MIS, human resources, general administration, executive
officers and professional fee expenses. General and administrative expenses in
the first quarter of 1997 were $675,678, or 17.0% of revenues, as compared to
$517,763, or 8.7% of revenues for the same period in 1996. The $157,915 increase
in the first quarter of 1997 as compared to the first quarter of 1996 was
attributable to an increase in the number of administrative employees and the
costs associated with being a public company.

Other Income, Net. Other income, net consists primarily of interest income from
short term investments. Other income, net improved from $107,414 for the first
quarter of 1996 to $222,997 for the first quarter of 1997. The improvement
resulted from the payoff of the Company's long term debt in February 1996 which
caused a reduction in interest expense.

Provision for Income Taxes: The Company's effective tax rate for the first
quarter of 1996 was 43.5%, consisting of a federal income tax rate of 33.8%,
combined with a weighted average state income tax rate of 9.7%. In the first
quarter of 1997, the Company's tax provision was $7,300, representing minimum
tax payments to various states. In the first quarter of 1997 a tax benefit for
net operating losses was not recognized as all federal tax loss carrybacks were
recognized in 1996.


LIQUIDITY AND CAPITAL RESOURCES


     The Company has historically financed its operations, including capital
expenditures, through cash flow from operations, cash and cash equivalent
balances, a bank line of credit and long-term debt. During the first quarter of
1996, the Company issued 2,300,000 shares of common stock in its initial public
offering, raising $25.6 million, net of expenses.

     In the first quarter of 1997, the Company used cash from operating
activities of $2,581,528 to fund a $2,200,036 net loss and an increase in
accounts receivable and generated cash through a decrease in income taxes
receivable. In the same period approximately $104,000 of cash was used for
investing and financing activities.

     In the first quarter of 1996, the Company generated approximately $24.1
million of cash from financing activities which consisted of $25.6 million, net,
from the sale of 2,300,000 shares of common stock in the Company's initial
public offering and used $1.5 million to pay off long-term debt. The Company
used $22,751 for investing activities which consisted of $220,937 for purchases
of property and generated $198,186 from other assets. In the first quarter of
1996 the Company generated $502,635 from operating activities through
collections on accounts receivable which was used in targeted inventory
procurement as well as reducing accrued liabilities.

     At December 31, 1995, the Company had a secured promissory note in the
amount of $1,541,667 due to Silicon Valley Bank which bore interest at the
bank's prime rate plus 3.0% (11.75% at December 31, 1995) per annum, payable
monthly in arrears. In February 1996 the Company paid the loan off in full,
without pre-payment penalty. In August 1996, the Company entered into a secured
lending arrangement (the "Agreement") with Silicon Valley Bank, providing for a
$5.0 million revolving line of credit bearing interest at the bank's prime rate.
The bank does not have a security interest in any of the Company's assets unless
the Company is borrowing under the line of credit and fails to comply with
certain financial covenants. The Agreement expires in August 1997 and has
certain financial and other covenants. At March 31, 1997, there were no
borrowings outstanding under the Agreement and the Company was in compliance
with all covenants. As such the bank held no security interest in any of the
Company's assets.

     The Company's principal commitment at March 31, 1997 consisted of a lease
on its office and manufacturing facility. The Company expects to spend
approximately $1.5 million for capital expenditures during 1997.

     The Company believes that existing cash resources, cash flows from
operations, if any, and line of credit facilities will be sufficient to fund the
Company's operations for at least the next twelve months.
