SANTA CLARA, Calif., Oct. 17, 2006 — Hyperion (Nasdaq Global Select: HYSL), the global leader in Business Performance Management software, today announced that Jon Temple, age 44, is joining the company as executive vice president of its Worldwide Field Organization.

In his new role, Temple leads Hyperion’s worldwide field organization, including all customer facing and revenue generating operations. Among his direct reports are the vice presidents of Hyperion’s three worldwide regions, as well as the global support, field marketing, channel and alliances, technical services and other field operational functions. Temple reports to Hyperion President and Chief Executive Officer Godfrey Sullivan and is a member of Hyperion’s executive management team.

Temple joined Above All Software in 2004 as president and chief operating officer and was appointed CEO in 2005.
