-- Worldwide monitor and module sales exceeded 2,480 units, an increase of 25% with the first full quarter of BIS VISTA sales

Aspect Medical Systems, Inc. , reported today that revenue was $22.6 million for the second quarter of 2006, an increase of 21% over revenue of $18.7 million in the second quarter of 2005. Product revenue was $21.2 million, a 17% increase from $18.2 million in the second quarter of 2005.

With the adoption of Statement of Financial Accounting Standards No.123R (SFAS No.123R) as of January 1, 2006, Aspect began reporting additional non-GAAP financial results that exclude the impact of stock-based compensation. The reconciliation of GAAP (U.S. generally accepted accounting principles) to non-GAAP results and guidance is contained in an attached table.

Key GAAP operating results for the second quarter of 2006 include:

-- Gross profit margin was 76.1% compared with 74.3% in the second quarter of 2005

-- Operating expenses were $15.9 million compared with $12.7 million in the second quarter of 2005

-- Net income was $2.1 million compared with $1.6 million in the second quarter of 2005

-- Net income per diluted share was $0.09 compared with $0.07 in the second quarter of 2005

Key non-GAAP operating results for the second quarter of 2006 include:

-- Gross profit margin improved to 76.6% compared with 74.3% in the second quarter of 2005

-- Operating expenses were $14.3 million, an increase of 13% from $12.7 million in the second quarter of 2005

-- Net income was $3.8 million compared with $1.6 million in the second quarter of 2005

-- Net income per diluted share was $0.16 compared with $0.07 in the second quarter of 2005

"We are pleased with several facets of our performance in Q2: the very successful launch of our new monitor, the BIS VISTA; rapid growth in our installed base; and continued improvement in operating margins and earnings per share. Having said that, growth in sensor revenue has moderated," said Nassib Chamoun, president and chief executive officer. "However, we remain confident about our future. We believe that attitudes towards brain monitoring are changing in a very positive direction, and that several of our initiatives, coupled with environmental factors, are likely to significantly expand the use of brain monitoring in the years ahead. Given our market leadership, the size of our installed base, and the rate it is growing, we believe we are very well-positioned to take full advantage."

Revenue Analysis - (see attached unaudited consolidated revenue data)

Domestic revenue was $17.8 million for the second quarter and $34.7 million for the six months ended July 1, 2006, an increase of 25% and 27%, respectively, over comparable periods in 2005. Domestic sensor revenue increased 18% for the second quarter of 2006 as compared to the second quarter of 2005. The increase resulted from a 16% increase in sensor unit volume combined with a 2% increase in sensor average unit price. Domestic equipment revenue increased by 27% due to a 143% increase in monitor and module units sold partially offset by a 43% decrease in average unit prices of the monitors as the result of significant BIS VISTA upgrade unit sales which are at a lower price point. Domestic strategic alliance revenue increased to $1.4 million in the second quarter of 2006 compared with $588,000 in the second quarter of 2005 as research and development activities under the Company's strategic research alliance with Boston Scientific increased.

International revenue was $4.8 million for the second quarter and $9.9 million for the six months ended July 1, 2006, an increase of 7% and 14%, respectively, over comparable periods in 2005. The growth in international revenue in the second quarter of 2006 from the second quarter of 2005 reflects a 34% increase in sensor revenue due to a 28% increase in sensor units sold and a 5% increase in average selling price. International growth is partially offset by a 19% reduction in equipment revenue due mainly to a 14% decline in monitor and module units sold.

Liquidity and Capital Resources

At July 1, 2006, the Company had cash, cash equivalents and marketable securities of $66.0 million compared to a balance of $61.3 million at December 31, 2005. The Company had no debt at July 1, 2006 and at December 31, 2005.

Outlook for the Third Quarter of 2006

For the third quarter of 2006, the Company is forecasting that total revenue will be within a range of $22.0 million to $22.75 million, product revenue will be within a range of $20.75 million to $21.5 million, and that net income per diluted share will be within a range of $0.07 - $0.09 on a GAAP basis. On a non-GAAP basis, the Company expects that net income per diluted share will be within a range of $0.14 to $0.16. See below under the heading "Use of Non-GAAP Financial Measures" for a discussion of the Company's use of such measures. See attached table for the reconciliation of GAAP to non-GAAP for the three and six months ended July 1, 2006.

Safe Harbor Statement

Certain statements in this release are forward-looking and may involve risks and uncertainties, including without limitation statements with respect to the Company's expectations with respect to revenue and net income for the third quarter of 2006 on both a GAAP and Non-GAAP basis, expected stock-based compensation expenses for the third quarter of 2006 and the Company's expectation that the Company's new VISTA monitoring product will achieve market acceptance and increase the installed base of BIS monitors in future periods. There are a number of factors that could cause actual results to differ materially from those indicated by these forward-looking statements. For example, the Company may not be able to control expenses or grow its sales force. The Company may also not be able to achieve widespread market acceptance of its BIS monitoring technology, or to compete with new products or alternative techniques that may be developed by others, including third-party anesthesia monitoring products approved by the FDA. The Company also faces competitive and regulatory risks relating to its ability to successfully develop and introduce enhancements and new products including the BIS VISTA monitor. In addition, the Company's ability to remain profitable will depend upon its ability to promote frequent use of the BIS system so that sales of its BIS sensors increase. The Company will not remain profitable if hospitals and anesthesia providers do not buy and use its BIS systems in sufficient quantities. Cases of awareness with recall during monitoring with the BIS system and significant product liability claims are among the factors that could limit market acceptance. There are other factors that could cause the Company's actual results to vary from its forward-looking statements, including without limitation those set forth under the heading "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2005 and the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended April 1, 2006, each as filed with the Securities and Exchange Commission.

In addition, the statements in this press release represent the Company's expectations and beliefs as of the date of this press release. The Company anticipates that subsequent events and developments may cause these expectations and beliefs to change. However, while the Company may elect to update these forward-looking statements at some point in the future, it specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing the Company's expectations or beliefs as of any date subsequent to the date of this press release.
