Sensory Science’s Reasons for the Merger

SLIDE 19

Primary Reasons

• Liquidity constraints

• Declining sales and margins

• Impaired ability to obtain product for sale

SLIDE 20

Sensory Science’s Financial Advisor:

Company unable to pay obligations in the absence of the SONICblue merger.

SLIDE 21

Sensory Science’s Board of Directors:

SONICblue merger “only currently available transaction . . .”

SLIDE 22

Factors Contributing to Sudden Downturn:

• VCR market dropped faster than industry or management had anticipated

• Digital TV market did not develop as quickly as industry forecasted

• Significant iCache Media Appliance initiative costs

SLIDE 23

These events led to an extraordinarily challenging environment and an inability to purchase
sufficient product for sale or to make appropriate R & D investments.

Sensory Science couldn’t weather all three events coupled with a falling stock
market.

SLIDE 24

SONICblue merger represented the best available opportunity for the company and
its stockholders.

Potential Benefits

• Integration of technological and engineering resources

• Product experience
