2. Microsystems Mbius Mobius Confidential Slide 2 of 14 Overview Technology and IP Mobius’ proven all-Si clock generation technology has the potential to reduce total platform power/heat by 20% and costs by 33% 1 patent issuing, 3 full-utility apps. pending, 3 apps. under development Business model Fabless: Design & sell clock components; outsource manufacturing and test Market and customers $3.4B available market in 2005 Validation of technology performance and value with 3 IP customers Team Raised $2M, built team, delivered to IP customers Investment opportunity Raising first institutional round of $8M to move to fabless model

3. Microsystems Mbius Mobius Confidential Slide 3 of 14 Entrenched Technology vs. Mobius’ Technology Mobius… eliminates the crystal, but retains the required frequency accuracy (±500ppm) eliminates the 2 pins on the package and 2 capacitors previously required for the crystal interface enables a new paradigm in power management with clock start-up latency and scaling in ns, not ms, thus providing the potential for 20-30% total platform power savings can serve applications in harsh environments (high T, G, etc.) Obviously valuable, but can Mobius achieve the required accuracy without the external frequency reference? YES ICS Master Timing Clock Mobius Master Timing Clock But can Mobius defend sockets on just cost/size? Maybe, but Mobius also addresses power
