Potential Questions from Clients

1. What is MPS Group’s relationship with Adecco at this time?

We are still competitors. It is business as usual for all MPS Group companies. The proposed acquisition is scheduled to close in first quarter 2010.

2. Was MPS Group acquired by Adecco?

No. On October 20, 2009, it was announced that MPS Group had agreed to be acquired by Adecco Group, a leading staffing and HR solutions company based in Switzerland. The acquisition still must be approved by our shareholders and by government regulators in the United States and Europe. We anticipate that these steps will be completed some time in the first quarter of 2010, and if so the transaction will be finalized at that time. The proposed acquisition will not close until first quarter 2010. Until then, there shouldn’t be any changes resulting from this transaction.

3. Why did Adecco want to acquire MPS Group?

MPS Group provides staffing, consulting, and solutions in the disciplines of information technology, finance and accounting, law, engineering, marketing and creative, property and healthcare. Adecco Group is an industry leader, and the acquisition of MPS Group expands Adecco’s capabilities into professional staffing segment. Adecco Group approached MPS Group because of the complementary nature of our business and geographic coverage, the strength of our business units, the way we do business, and the talents of our people. MPS Group is an excellent fit for Adecco.

4. Why did MPS Group agree to be acquired by Adecco?

The MPS Group Board of Directors and MPS Group Executives have an obligation to look out for the best interests of the Company’s shareholders. Adecco offered $13.80 per share, a substantial premium to our recent stock price and historical weighted average price over a longer period of time. And, it is a very good multiple of both trailing and projected EBITDA (earnings before taxes, interest, depreciation, and amortization). The Board felt that it was in the best interests of the shareholders

to accept the offer made by Adecco. Additionally, the Board felt that the combination made good strategic sense for our employees and clients.

5. What is the impact of the transaction on Beeline’s delivery model?

Beeline plans to continue offering our current services including our industry leading vendor neutral managed services, continue to enhance and extend our application suites, and work with our market partners.
