CalPERS Acquires Minority Stake in Silver Lake

Agreement Provides Permanent Capital Base to Support Silver Lake
Growth
NEW YORK & MENLO PARK, Calif.--(Business Wire)--Silver Lake, the leader in large private investments in
technology, technology-enabled, and related growth industries,
announced today that it has entered into a long-term strategic
partnership with the California Public Employees' Retirement System
(CalPERS) under which CalPERS has acquired a minority ownership stake
in Silver Lake.

Under the agreement, CalPERS has purchased a 9.9 percent stake in
Silver Lake Group and related entities that own and direct Silver Lake
and oversee all of its investment activities. CalPERS also has
committed to making additional investments as a limited partner in
Silver Lake funds. A representative from CalPERS will join Silver
Lake's Management Advisory Board.

The CalPERS investment provides Silver Lake with a permanent
capital base to help the firm continue to generate superior rates of
return for its limited partner investors by funding Silver Lake's
future growth, strengthening and expanding Silver Lake's global
capabilities and footprint, and extending Silver Lake's leadership
position in technology investing. The investment also will provide
Silver Lake with seed capital for the development of future funds and
other new alternative asset business opportunities, as well as expand
the ability of Silver Lake to commit to/co-invest alongside its funds.

Glenn Hutchins, co-founder and co-chief executive of Silver Lake,
said, "The CalPERS investment and strategic partnership with us
provide tremendous benefit to Silver Lake and our limited partners by
bringing important long-term funding that supports expansion of our
technology investment leadership. We are extremely pleased to have
this vote of confidence from CalPERS as we focus on building out our
successful platform to drive the future growth of Silver Lake and
continue creating superior value for our investors. We look forward to
taking full advantage of the insight and experience that CalPERS will
bring to our firm."

Leon G. Shahinian, Senior Investment Officer of CalPERS
Alternative Investment Management Group, said, "CalPERS' commitment to
Silver Lake underscores Silver Lake's compelling track record as a
leading technology-focused investment firm and a top performer in
their fund vintage years. They have consistently demonstrated success
in creating value for their investors, and our partnership is a
natural progression of a mutually beneficial relationship dating from
1999 when CalPERS was an LP in Silver Lake's first fund. As one of
Silver Lake's earliest investors, we are excited to expand our
relationship with Silver Lake in a manner that allows us to
participate more fully in the firm's continued growth and success as
the firm expands its business platform and investment strategy into
new markets and geographies."

The firm invests in large-cap technology companies through its
Silver Lake Partners funds, the largest private equity funds ever
raised for investment in technology, technology-enabled, and related
growth industries. The firm recently expanded its investment scope
through Silver Lake Sumeru, the firm's middle-market investing
