"Our Digital Entertainment business segment, which comprises DTV, DVD, PC video/audio and video IP, achieved several milestones including the successful launch of the advanced Vaddis 7 DVD processor, and the ongoing transition of customers to our Generation 9 HDTV product family. In our Digital Imaging market segment, which includes digital camera processors, CMOS sensors, digital Multi-Function Peripherals (MFP) ICs and digital printer software, we introduced the COACH 7 digital camera processor, and production shipments are expected to begin in the third quarter. There were new deployments of Zoran's flagship Integrated Print System (IPS) software and OEMs are continuing to design new systems with our latest Quatro MFP IC products.

Future Outlook

The following statements are based on current expectations. These statements are forward looking, and actual results may differ materially.

The Company is currently expecting second quarter 2004 revenues to increase 12 to 18 percent from first quarter levels with gross margins ranging between 42.5 and 43.5 percent. Pro forma operating expenses, excluding acquisition related costs, are expected to be in a range of $34.5 to $36.0 million. Pro forma earnings per share are expected to range between $0.08 and $0.11 per diluted share, on 45.2 million shares. Acquisition-related costs to be included under GAAP should be approximately $12.5 million which would generate a GAAP loss of $0.18 to $0.21 for the second quarter on 42.7 million common shares. For the full year the Company is raising its annual revenue growth forecast to 65 to 75 percent and is establishing its annual pro forma earnings per share forecast of 41 to 52 percent over 2003 levels. Acquisition-related costs to be included under GAAP for the full year should be approximately $50 million which would generate a GAAP loss of $0.44 to $0.47 per common share.

Zoran will provide more commentary on its first quarter results and full year 2004 outlook during the earnings conference call.

About Pro Forma Adjustments

To supplement the consolidated financial results prepared under generally accepted accounting principles ("GAAP"), the Company uses a pro forma measure of net income that consists of GAAP net income adjusted to include or exclude certain costs, expenses and gains. Pro forma net income gives an indication of the Company's baseline performance before gains, losses or other charges that are considered by management to be outside of our core operating results. In addition, pro forma net income is among the primary indicators management uses as a basis for planning and forecasting future periods. These measures are not in accordance with or an alternative for GAAP and may be materially different from pro forma measures used by other companies. The Company computes pro forma net income by adjusting GAAP net income for the impact of amortization of acquisition-related charges and other non-recurring charges and gains.
