Acquisition Adds Complementary High Speed Interface IP Business

SUNNYVALE, Calif.–(BUSINESS WIRE)–Jun. 6, 2009–
MoSys, Inc. (NASDAQ: MOSY), a leading provider of high-density
system-on-chip (SoC) memory intellectual property (IP), today announced
the acquisition of substantially all of the assets and business of
privately held Prism Circuits, Inc., a profitable supplier of high data
rate parallel and serial interface (I/O) IP.

The acquisition is expected to result in the following benefits:

  • Expand MoSys’ product portfolio and addressable markets with the
    addition of highly valued and differentiated IP
  • Accelerate the growth opportunity for MoSys’ 1T-SRAM IP in the
    networking and communications markets and provide stronger customer
  • Increase revenue and generate positive cash flow for the second half
    of 2009 and 2010
  • Add a world-class team of engineers, including a highly talented,
    cost-efficient engineering design center in India

Founded in 2006 and based in Santa Clara, California, Prism Circuits
specializes in silicon-proven, low-power, serial interface IP cores
(SerDes) with data rates running at 10 gigabits per second and above,
and IP cores for DDR 3 and DDR 2 parallel interfaces. Prism Circuits has
established customer relationships with tier one companies such as
Fujitsu, Microsoft and Juniper, as well as strong foundry relationships
with Fujitsu and TSMC, which MoSys expects to build on and improve.

“This acquisition is a major step towards driving growth and achieving
our vision of becoming a world class provider of differentiated, high
value IP for SoC designers,” commented Len Perham, MoSys’ President and
CEO. “Acquiring Prism Circuit’s high speed SerDes and DDR interface IP
significantly expands our market opportunity, fuels the expansion of our
core 1T-SRAM business into packet processing applications in the
networking and communications markets and brings us a talented
engineering team. The synergistic combination of our differentiated,
embedded memory IP with the high-speed interface IP from Prism Circuits
will allow us to bring an even more compelling value proposition to our
customers and partners.”

“When I founded Prism Circuits in 2006, my goal was to build a company
based on a foundation of an incredibly talented team of engineers and
very differentiated, high data rate serial and parallel interface IP. I
am proud of what the Prism Circuits team has accomplished in creating
great technology and building successful customer relationships with
leading companies such as Fujitsu and Microsoft. I am very excited about
joining forces with MoSys to take our team and technology to the next
level,” commented Sundari Mitra, CEO of Prism Circuits. “Becoming part
of an established public company enables us to leverage MoSys’ global
resources and sales channels to further the expansion of our interface
IP business. Our combined teams and technology will create exciting
growth opportunities for MoSys and our employees, while at the same time
allowing us to provide a vastly wider array of solutions to our
customers’ future systems designs.”

Under the terms of the agreement, MoSys paid approximately $13.5 million
at the closing, and potentially will pay an additional earn-out amount
of up to $6.5 million after the first anniversary of the closing date,
subject to the attainment of specified milestones during the initial
12-month post-acquisition period. MoSys has not assumed any Prism stock
options or employee equity incentive awards but has agreed to grant up
to a maximum of 3.7 million shares of MoSys common stock under stock
options or restricted stock units (RSUs) to 25 newly hired former Prism
Circuits employees (with one RSU share equated to three option shares
for this purpose). The stock options and restricted stock units will be
granted as inducements material to the employment of these new employees
in accordance with NASDAQ Marketplace Rule 5635(c)(4).
