TriNet Acquires Customer Assets of Outsource Group

HR Outsourcing Firm Adds Nearly 200 Customers as a Result of the Transaction

SAN LEANDRO, Calif. (July 11, 2006) - TriNet, a nationwide provider of human resource (HR) outsourcing services for small and mid-sized companies, today announced the purchase of the customer assets of Outsource Group, a nationwide HR services provider based in Walnut Creek, California. The transaction includes customer contracts for nearly 200 companies and also includes the rights to Outsource Group's name and web site. In addition, certain employees of Outsource Group will become full-time team members of TriNet, adding to the company's extensive industry experience and assisting with the company's growth objectives. Specific terms of the transaction are not being disclosed.

"Outsource Group has provided a very high quality of HR outsourcing services to small and medium-sized companies since 1998, and transitioning our business to TriNet's platform enables us to continue to offer superior service and technology support to our customers," said Kevin Grauman, Outsource Group's President and CEO. "I'm very enthusiastic that TriNet's market presence, industry experience, and service-focus will greatly benefit our customers in California and across the country."

"TriNet sees the successful completion of this transaction as a validation of our multi-line benefits offering and concurrent nationwide PPO networks," said Martin Babinec, TriNet's President and CEO. "Our benefits package will deliver competitive rates and unparalleled depth and flexibility to Outsource Group's customers-as well as the advantages of our self-service portal and human capital management support."

TriNet welcomes the opportunity to work with Outsource Group because the company's customer base is aligned with TriNet's target profile of highly compensated workforces within the industries of technology, financial services, and professional services. TriNet tailors its benefits plans and online services to meet the high expectations of employees within these industry segments.

TriNet has previously acquired the customer assets of the E3 Group in Texas, as well as books of business from ALTRES in Hawaii and HR Logic in Boston. TriNet also received a substantial investment from General Atlantic partners, a leading private equity firm with approximately $10 billion under management, in July of 2005.
