Exhibit 99.4

[FORM OF EMAIL TO PROSPECTS]

Subject: Gevity Announces Proposed Merger With TriNet

Dear [Prospect Name]

Today, Gevity announced that we have entered into a definitive merger agreement with TriNet Group, Inc. TriNet is a privately held provider of human resources services for small to medium sized businesses. TriNet’s largest shareholder, General Atlantic, LLC, a global growth equity firm, also owns approximately 9.5% of Gevity’s outstanding common stock. We believe the new organization created by this merger will build upon the complimentary strengths of both companies to provide superior value for our clients.

This announcement has no impact on the terms of the pricing proposal we have developed for your business.

This proposed transaction, subject to regulatory and shareholder approval, is expected to be completed in the second quarter of 2009. In the meantime, both companies will continue to operate their businesses independently. Our commitment to client service remains our highest priority.

I look forward to building a relationship with you and your business. We intend to keep you informed about the positive impact this announcement may have on your business.

Additional information about the transaction can be found in our press release, which can be accessed at gevity.com. Should you have any questions, do not hesitate to contact me at XXX.XXX.XXXX or via email colleague.name@gevity.com.

Sincerely,

[BDM Name]
