IMPORTANT INFORMATION

5 December 2011

Dear Shareholder

OFFER PRICE INCREASED TO $3.75, AS 91.55% ACHIEVED CLOSING DATE EXTENDED TO 19 DECEMBER 2011

Seven (National) Pty Limited ACN 153 299 159 ( Seven ) has a relevant interest in 98.7% of the ordinary shares in National Hire Group Limited ( National Hire ) on issue and has obtained enough acceptances under its takeover bid that it is now entitled to compulsorily acquire the remaining shares in National Hire that are not owned by the Seven Group Holdings Limited group of companies.

Seven had said that if this occurred it would vary the offer under its takeover bid to increase the offer price to $3.75 per ordinary share in National Hire.

In accordance with this intention, Seven has varied the offer consideration under its takeover bid to $3.75 per ordinary share in National Hire.

If you have already accepted the offer you will automatically be entitled to receive the increase in the offer price, which is an additional $0.40 for every ordinary share in National Hire. If you now decide to accept Seven’s offer you will be paid $3.75 per share (instead of $3.35). Seven will issue payments to accepting National Hire shareholders within 5 business days of their acceptance.

Seven will fund the additional cash consideration in the same way as described in section 5 of its bidder’s statement dated 4 October 2011.

As a result of the increase in the offer price to $3.75, the offer period has been automatically extended for a further period and will now close at 7pm (Sydney time) on Monday, 19 December 2011. Enclosed is a formal notice of variation for the increase in offer price to $3.75, as required by the Corporations Act 2001 (Cth).

If you have already accepted Seven’s offer you need not take any action. If you have not, I strongly urge you to accept the offer without delay to take advantage of the unique exit opportunity.

If you have any queries in relation to Seven’s offer, please contact the Seven Offer Information Line on 1300 233 947 (for callers within Australia) or +61 2 9290 9600 (for callers outside Australia).

Yours faithfully
