Allied Domecq PLC Bid for Peter Lehmann Wines Limited Declared Unconditional

Allied Domecq PLC (Allied Domecq) today announces that it has declared its Offer for Peter Lehmann Wines Limited (PLW), through its wholly owned subsidiary Allied Domecq Wines Australia Pty, free of all remaining conditions. Allied Domecq will also accelerate dispatch of payment to shareholders to within five days after acceptance.

This decision has been made following completion of Allied Domecq's review of the PLW Target's Statement and final due diligence.

The Allied Domecq Offer of $4.00 per PLW share represents a 15 cents per share (3.9%) premium to the $3.85 per share offer by Hess Group Australia Pty Ltd.

Commenting on developments, Allied Domecq Chief Executive Philip Bowman said:

"PLW shareholders can now compare two unconditional offers, which both provide for payment within five days of acceptance. At $4.00 per PLW share, the Allied Domecq offer is 3.9% higher than the Hess offer and guarantees shareholders an extra 15 cents per share.

"We look forward to receiving the endorsement of the PLW Independent Directors and encourage PLW shareholders to accept our Offer without delay."

[HESS LOGO]


HESS INCREASES ITS UNCONDITIONAL BID FOR
PETER LEHMANN WINES (PLW) TO $4.00

Hess Group Australia (Hess) today increased its unconditional cash offer to $4.00 per PLW share. Hess will pay the increased price of $4.00 per share to any PLW shareholder who has already accepted the previous Hess offer of $3.85 per share.

PLW is likely to continue with a number of minority shareholders after the close of the offers. This is because, given Mr Peter Lehmann's publicly stated intention not to sell any of his shares, neither Hess not Allied would be able to compulsorily acquire those shareholders who do not accept an offer.

The Hess offer, at $4.00 per share, is now at the same price as the offer made by Allied. However, the two offers are not the same, and the intentions of the bidders are not the same. Hess believes the interests of PLW and its shareholders are best served by the Hess Offer for a number of reasons.

Hess has great respect for the PLW business, its branding, its management, and its future and believes it can help continue the growth and success of PLW.

Hess encourages PLW shareholders to accept the Hess Offer. Those who do will be paid within five days of Hess receiving a valid acceptance.

Annexure C—PLW announcement

[PETER LEHMANN LOGO]


UPDATE ON TAKEOVER OFFER

Peter Lehmann Wines ("PLW") notes the recent amendments to the Allied and Hess Offers announced on 9 October 2003. Both Allied and Hess are now offering $4.00 cash per PLW share and both Offers are unconditional.

The situation remains fluid and there could be a further change to either Offer.

The Independent Directors, Messrs Richard England, Harold Tilley and Neil Lister, intend to meet on Tuesday 14 October, to provide their final recommendation to enable shareholders sufficient time to accept an offer.

Notwithstanding this, the Directors of PLW believe it is appropriate to convey their current views to shareholders.

The Directors note each Offer is identical in terms of price, payment terms and being unconditional. However, the Hess Offer allows you to accept for only part of your shareholding if you wish.

The Independent Directors believe it is important to make a recommendation to shareholders for one of the Offers and have therefore considered the following factors:-

Having taken all of these factors into account, the Independent Directors intend to recommend that, on balance, shareholders accept the Hess Offer for all of their PLW Shares, subject to no better offer emerging but continue to advise that shareholders wait for further advice.

All PLW Directors consider there are a number of implications for shareholders electing to remain as minority shareholders in PLW. These are explained in detail in the Target's Statement which has already been sent to you.

In light of the variations to each Offer the Non Independent Directors, Messrs Doug Lehmann, Roger Wilson and Robert Edwards, confirm their opinion the Hess Offer is the better Offer for all shareholders and the Company.

For clarity during this interim period, the Directors also wish to advise Shareholders of the following:

a)
Acceptance of the Hess Offer

9


b)
Acceptance of the Allied Offer

PLW shareholder that have any questions should contact PLW's shareholder information line on 1800 008 842.

Allied Domecq PLC to accept revised Hess offer for
Peter Lehmann Wines Limited

Allied Domecq PLC (Allied Domecq) today announced that it proposed to accept the revised offer by Hess Group Australia Pty Ltd (Hess) for Peter Lehmann Wines Limited (PLW).

On 9 October 2003, Hess announced that it proposed to match the Allied Domecq offer by increasing its unconditional offer for PLW to $4.00 per share. The Independent Directors of PLW subsequently announced that they intend to recommend that shareholders accept the Hess offer for all of their shares, subject to no better offer emerging.

Commenting on developments, Allied Domecq Chief Executive Philip Bowman said:

"While we remain firm believers in the potential of PLW under the control of Allied Domecq, we have an obligation to generate value for our own shareholders. Despite the significant cost and revenue synergies that we believe would accrue to PLW as part of the Allied Domecq group, we do not believe that it would be in the interests of our shareholders to increase our offer further."

"Accordingly, we have informed the board of PLW that we propose to accept the Hess offer for our entire stake. In order to minimise ongoing uncertainty for PLW, we would encourage other shareholders to do the same."

PLW produce some exceptional wines; I wish the company and its employees every success going forward."

Allied Domecq will also apply to the Australian Securities and Investments Commission for consent to withdraw its offer.
