BBSI Reaffirms Guidance for Second Quarter 2006 and Schedules Conference Call

VANCOUVER, Wash.--(BUSINESS WIRE)--June 14, 2006--Barrett Business

Services, Inc. (Nasdaq:BBSI) reported today that management has

reaffirmed its previously disclosed limited financial guidance with

respect to its operating results for the second quarter ending June

30, 2006, and will convene a conference call, Wednesday, June 14,

2006, at 9:00 a.m. PT.

Consistent with the Company's prior disclosure on April 26, 2006,

management expects gross revenues for the second quarter of 2006 to

range from $250 million to $255 million, an increase of approximately

37.5% over the second quarter of 2005, and anticipates diluted

earnings per share for the second quarter of 2006 to range from $.33

to $.35 per share. Management expectations for diluted earnings per

share for the second quarter of 2006 equate to increases over the

second quarter of 2005 of approximately 36.9% in net income and

approximately 9.7% in diluted earnings per share. The percentage

increase in expected net income for the 2006 second quarter exceeds

the percentage increase in expected diluted earnings per share due to

the dilutive effect of the July 2005 follow-on equity offering. A

reconciliation of estimated gross revenues to estimated GAAP net

revenues for the second quarter of 2006 is not included because PEO

revenues and cost of PEO revenues for the period are not reasonably

estimable.

On June 14, 2006, at 9:00 a.m. Pacific Time, William W. Sherertz

and Michael D. Mulholland will host an investor telephone conference

call to discuss management's reaffirmation of its financial guidance

for second quarter 2006 operating results. To participate in the call,
