With reference to the joint press releases of 1 April, 17 April, 22 April, 23 April, 7 May 2008 and the joint announcement of 2 April 2008, Randstad Holding nv ("Randstad Holding" or the "Offeror") and Vedior N.V.

Terms not defined herein shall have the meaning as set out in the offer memorandum and prospectus dated 1 April 2008 (the "Offer Memorandum").

"We regard this successful tender result as a vote of confidence in the combined group", says Ben Noteboom, CEO of Randstad Holding." We plan to move forward swiftly to be able to make optimal use of our combined strengths as soon as possible. This is in the best interest of all stakeholders. All our employees, from both sides, can focus as soon as possible on the new opportunities. Our clients can benefit from a broadened service portfolio. This stimulates growth, which, in combination with the ability to realize identified synergies quickly, benefits our shareholders."

"A historic moment for Vedior and Randstad and an achievement of both teams", says Tex Gunning, CEO of Vedior. "The combination will have a unique opportunity to 'shape the world of work' and contribute to value creation for all stakeholders. I have been impressed by our new colleagues and have great confidence in the future of the combined company."

Acceptances

During the initial Acceptance Period, which ended at 17.30 hours, Amsterdam time, on 9 May 2008 (the "Acceptance Closing Date"), 136,945,616 Shares have been tendered for acceptance under the Offer. The Shares tendered for acceptance under the Offer represent 78.48% of the issued and outstanding capital of Vedior and, based on the Offer Price per Share, as adjusted (as described

below), have an aggregate value of EUR 2.54 billion based on the Randstad Holding closing share price on the Acceptance Closing Date.

The Shares tendered under the Offer together with the 26,149,000 shares already held by Randstad Holding for its own account at the Acceptance Closing Date (14.98%) amount to a total of 163,094,616 Shares, which represent 93.46% of the issued and outstanding capital of Vedior.

Settlement

With reference to the Offer Memorandum, Shareholders who accepted the Offer shall receive the Offer Price per Share, which is cum dividend 2007, for each Share validly tendered (or defectively tendered provided that such defect has been waived by the Offeror) and delivered (geleverd) on the terms and subject to the conditions and restrictions of the Offer as described in the Offer Memorandum. As announced on 7 May 2008, as a result of the 2007 dividends of Randstad Holding and Vedior the Cash Consideration of the Offer Price per Share has been adjusted from EUR 9.50 per Share to EUR 9.55 per Share. Payment of the Offer Price per Share, as adjusted, shall occur on the Settlement Date, which will be on 16 May 2008.

Post Offer restructuring, liquidity and delisting

As soon as legally possible and practicable, the Offeror intends that the listing of the Shares on Euronext Amsterdam will be terminated. A delisting will adversely affect the liquidity and market value of the remaining Shares.

There will be no post Acceptance Period. As further described in Section 4.18 (Post Offer restructuring of Vedior) of the Offer Memorandum, Randstad intends to expeditiously effectuate a statutory legal merger (juridische fusie) in accordance with Part 7 of Book 2 of the Dutch Civil Code, as a result of which Vedior will disappear and Randstad will survive and acquire all assets and liabilities of Vedior by operation of law. Shareholders that have not tendered their Shares under the Offer during the initial Acceptance Period will then become, by operation of law, shareholders in Randstad Holding. Such statutory legal merger, which is subject to the required corporate authorizations, without a post Acceptance Period, aims to ensure rapid integration wherever necessary and to realise identified cost and tax synergies as soon as possible.

The Offeror may initiate any of the other post Offer restructuring measures as set out in Section 4.18 (Post Offer restructuring of Vedior) of the Offer Memorandum.
