This represents the beginning of the rollout of our Uniphi solution that will continue through the remainder of the year.”

SECOND QUARTER OPERATIONAL HIGHLIGHTS:

Some of these Aspect customers included: Accent Marketing Services, AMICA Insurance, CitiCorp North America, Comcast Cable, Garlands, Gerling, HealthNet, Royal Bank of Scotland, StarTek, Inc., and Washington Mutual.

BUSINESS OUTLOOK:

The following statements are forward-looking, and actual results may differ materially:

• The company is planning for third quarter total revenue to be the same as or grow slightly from the second quarter.

• The company expects Q3 gross margins to remain generally consistent with Q2 levels. Variability in gross margin percentages is dependent upon, among other factors, the mix and volume of revenues.

• Operating expenses for the third quarter are expected to be in a range of $37 million to $39 million.

The company will host a conference call and web-cast today at 2:00 pm Pacific Time to discuss second quarter 2004 results.

Notes on financial presentation: Actual financial results are prepared in accordance with U.S. generally accepted accounting principles.

Certain statements contained in this press release, including but not limited to, statements relating to expected product rollout, third quarter total revenue, gross margins, and operating expenses are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities and Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995, and are made under its safe-harbor provisions. Such forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those projected. Specific factors that may cause actual revenue and earnings per share results to differ include: the significant percentage of Aspect’s quarterly sales consummated in the last few days of the quarter and the potential for delays in closing of sales or product deliveries make financial predictions especially difficult and raise a substantial risk of variance in actual results; changes in the overall mix and volume of product line revenues can have a significant impact on gross margin and profitability; fluctuations in our North American and International business levels and/or economic conditions, the hiring and retention of key employees, insufficient, excess or obsolete inventory and variations in valuation, and foreign exchange rate fluctuations can all cause revenues and income to fall significantly short of anticipated levels. The economic, political and other uncertainties caused in the United States and throughout other regions of the world add to these challenges. Additional risks that could cause actual results to differ materially from those projected are discussed in Aspect’s Form 10-K/A for the year ended December 31, 2003 and Form 10-Q for the quarter ended March 31, 2004, as filed with the Securities and Exchange Commission. Readers are cautioned not to place undue reliance on these forward-looking statements, which reflect management’s analysis only as of the date hereof. Aspect undertakes no obligation to publicly release the results of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

(1) Pursuant to GAAP, the Company is required to present earnings per share “as if” all earnings were distributed to Common and Preferred Shareholders. Under this “two class” method, earnings are allocated to Common and Preferred Shareholders in proportion to their respective ownership interests. This calculation for the three months ended June 30, 2004 would allocate approximately 73% of the current earnings to Common Shareholders and yield $0.15 earnings per share per Common Shareholder, as shown above. The calculation for the six months ended June 30, 2004 would allocate approximately 72% of the current earnings to Common Shareholders and yield $0.32 earnings per share per Common Shareholder, as shown above. However, the Company has not in the past, and does not currently intend to, declare a distribution of earnings. Absent this “as if” apportionment, diluted earnings per Common share would be $0.17 for the three months ended June 30, 2004 and $0.35 for the six months ended June 30, 2004.
