GEVITY ANNOUNCES PROPOSED MERGER WITH TRINET

Dear [Notice Contact]:

Today, Gevity announced that it has entered into a definitive merger agreement with TriNet Group Inc., pursuant to which TriNet would acquire all of the outstanding common stock of Gevity in an all-cash transaction. This transaction is expected to close in the second quarter of 2009 and is subject to the approval of Gevity’s shareholders, regulatory approvals and other customary closing conditions. Following the closing, the combined companies will be privately held.

Gevity and TriNet are committed to making this transition virtually transparent to you and your employees. To that end, we will not be making any changes as a result of today’s announcement — your pricing, health insurance carrier, workers’ compensation coverage and 401(k) provider will remain the same. The phone and fax numbers you use to contact Gevity have not changed. You will still report your payroll in the same way you do today. Your HR Consultant (HRC) and Service Center representatives remain committed to bringing you the highest quality service.

Who is TriNet?

TriNet is an industry leader, with strong financial backing and a commitment to the Professional Employer Organization (PEO) model. Combined, TriNet and Gevity represent more than 45 years at the forefront of the PEO industry. We believe that the potential combination of our two experienced and well-respected companies represents an excellent blend of vision, mission, and purpose.

Until the proposed transaction closes, each company will continue to operate independently. We are committed to keeping you informed and will be communicating with you regularly throughout the pre-closing period. Additional information can be found in our press release, which is available at gevity.com, and in the enclosed FAQ document.

As always, we appreciate the opportunity to serve you and look forward to continuing our business partner relationship. If you have any questions, please call your HRC or our Service Center at 1.800.2GEVITY (1.800.243.8489).

Sincerely,

/s/ Michael Lavington
