Small adjustment of Offer Price per Share as a result of 2007 dividend

With reference to the joint press release of 1 April 2008, by which Randstad Holding nv and Vedior N.V. announced the launch of Randstad Holding's recommended mixed cash and share exchange offer (the "Offer") to all holders of issued and outstanding Vedior shares (the "Shares"), Randstad Holding and Vedior jointly announce that the Cash Consideration of the Offer Price per Share has been adjusted, from € 9.50 to € 9.55, as a result of the declared 2007 dividend.

As indicated in the joint press release of 1 April 2008 and section 4.3 of the offer memorandum dated 1 April 2008 (the "Offer Memorandum"), the Offer Price per Share is cum dividend. In the event that any 2007 dividend or other distribution on the Shares would be declared by Vedior (whereby the record date that is decisive for entitlement to such distribution takes place prior to Settlement), the Cash Consideration would be decreased by the full amount of any such distribution payable on each Share. In the event that any 2007 dividend or other distribution on the Randstad Holding share would be declared by Randstad Holding (whereby the record date that is decisive for entitlement to such distribution takes place prior to Settlement), the Cash Consideration would be increased by an amount equal to 32.759% of any such distribution on each Randstad Holding share.

At the annual general meeting of shareholders of Vedior held on 25 April 2008, the shareholders resolved to pay a 2007 dividend of EUR 0.36 per Share, payable on 6 May 2008 (record date 2 May 2008). At the annual general meeting of shareholders of Randstad Holding held today, the shareholders resolved to pay a 2007 dividend of EUR 1.25 per Randstad Holding share, payable on 28 May 2008 (record date 13 May 2008).

As a result of the 2007 dividend, and considering Settlement after 13 May 2008, the Cash Consideration of EUR 9.50 will be decreased by EUR 0.36 and increased by EUR 0.41 (32.759% of EUR 1.25) which leads to an adjusted Cash Consideration of EUR 9.55.

The acceptance period under the Offer closes at 17.30 hours, Amsterdam time, on 9 May 2008. Acceptances under the Offer must be made in the manner specified in the Offer Memorandum.
