Share exchange ratio determined

Share exchange ratio for statutory legal merger determined at 0.67258 Randstad Holding share for each Vedior share

With reference to the joint press releases of 1 April, 17 April, 22 April, 23 April, 7 May 2008, 13 May 2008 and the joint announcements of 2 April 2008 and 14 May 2008, Randstad Holding nv ("Randstad Holding" or the "Offeror") and Vedior N.V. ("Vedior" or the "Company") hereby announce that the merger proposal and the explanatory notes thereto with respect to the statutory legal merger (juridische fusie) between Vedior and Randstad Holding have been signed by the Management Boards and Supervisory Boards of each of Vedior and Randstad Holding and will be submitted with the Chamber of Commerce on 16 May 2008.

As a result of the statutory legal merger, Vedior will disappear and Randstad Holding will survive and acquire all assets and liabilities of Vedior by operation of law. The remaining Vedior shareholders, who have not tendered their Vedior shares under the Offer during the initial Acceptance Period, will consequently by operation of law, become shareholders in Randstad Holding. This statutory legal merger, which is subject to approval by the general meeting of shareholders of Vedior, is intended to expedite integration and to realise the identified cost and tax synergies as soon as possible. A general meeting of shareholders of Vedior in which the merger proposal will be voted upon is expected to be held in the second half of June. Randstad, as a majority shareholder will in this general meeting vote in favour of the merger proposal.

Share Exchange Ratio

In exchange for each Vedior share, with a nominal value of EUR 0.05 each, Randstad Holding shall distribute by operation of law (toekennen) to the holder (other than Randstad Holding), 0.67258 Randstad Holding shares with a nominal value of EUR 0.10 each.

The share exchange ratio is based on the Offer Price of EUR 9.55 cash (as adjusted for declared 2007 dividend) and 0.32759 Randstad Holding shares for each Vedior share. On 13 May 2008, Randstad declared the Offer unconditional. The volume-weighted average price of the Randstad share on 13 May 2008 was EUR 27.682.

Therefore, the share exchange ratio is 0.32759 (the share consideration in the Offer) plus EUR 9.55 divided by EUR 27.682, which equals 0.67258.

Issue of new Randstad Holding shares at Settlement

Settlement of the Offer will occur on 16 May 2008. The number of Randstad Holding shares to be issued on 16 May is 45,035,668.

Application has been made for listing and admission to trading of the new Randstad Holding shares on Euronext Amsterdam by NYSE Euronext (ISIN: NL0000379121).

Integration progress

The Board of Management and Supervisory Board of Vedior have approved to start with the post Offer restructuring of Vedior's French activities in conformity with the terms as set out in section 4.19 of the offer memorandum and prospectus dated 1 April 2008 (the "Offer Memoradum"), subject to approval by the general meeting of shareholders of Vedior. This restructuring has no bearing on the statutory legal merger between Vedior and Randstad Holding or the share exchange ratio under such statutory legal merger and is, like the statutory legal merger, intended to expedite integration.
