Bonds due 2013 (£100,000,000 of which were issued on 7 March 1989 (the Original Bonds) and a further £100,000,000 of which were issued on 13 May 1992 and consolidated to form a single series with the Original Bonds (the New Bonds and, together with the Original Bonds, the Bonds)) and Proposal by the Company to the holders of such Bonds (Bondholders) Hammerson plc (the Company) hereby announces its intention (i) to invite (the Offer) all eligible holders of the Bonds to tender such Bonds for repurchase by the Company for cash and (ii) to invite all Bondholders to approve a proposal (the Proposal) to amend the terms and conditions of the Bonds to provide for the Company to have the option to redeem the Bonds early, subject to the terms and conditions of the Tender Offer Memorandum dated 3rd May 2006 (the Tender Offer Memorandum). Copies of the Tender Offer Memorandum are available from the Dealer Manager and the Tender Agent as set out below. Notice (the Notice) of a meeting (the Meeting) of the Bondholders to be held at the offices of Herbert Smith LLP at Exchange House, Primrose Street, London EC2A 2HS on Thursday 25th May 2006 at 11.00 a.m. is to be published in the Financial Times on the Launch Date. The price payable for the Bonds (the Repurchase Price) will be determined at or around 11.00 a.m., London time, (the Pricing Time) on 26th May 2006 (the Pricing Date) in the manner described in the Tender Offer Memorandum by reference to the sum (such sum, the Repurchase Yield) of the repurchase spread of 65 basis points (bps) (the Repurchase Spread) and the Offer Side Benchmark Security Rate. The Offer begins on 3rd May (the Launch Date) and expires at 5.00 p.m., London time, on Monday 22nd May 2006 (the Expiration Deadline), unless the period for the Offer is extended or re-opened or the Offer is terminated. In order to be eligible to receive the Repurchase Price, Bondholders must validly tender their Bonds before the Expiration Deadline, by delivering, or arranging to have delivered on their behalf, a valid Bond Tender Instruction that is received by the Tender Agent before the Expiration Deadline. Each Bondholder who validly tenders its Bonds (and does not revoke such tender) before 5.00 p.m., London time, on Tuesday 16th May 2006 (the Early Tender Deadline) will receive a further cash payment (the Early Tender Premium) in addition to the Repurchase Price and Accrued Interest, and as additional consideration for its tender of the relevant Bonds, for each £10,000 in principal amount of such Bonds accepted pursuant to the Offer. The amount of the Early Tender Premium for such Bondholder will be equal to the difference between the Repurchase Price of the relevant Bonds and an effective repurchase price (the Effective Early Tender Price) of such Bonds determined in the same manner as for the Repurchase Price but by reference to the sum (such sum, the Effective Early Tender Yield) of an effective repurchase spread of 55 bps (the Effective Early Tender Spread) and the Offer Side Benchmark Security Rate. Bondholders to whom the Offer is not being made pursuant to the offer restrictions set out in the Tender Offer Memorandum (each an Ineligible Bondholder) may also be eligible, to the extent permitted by applicable laws and regulations, to receive an identical amount to the Early Tender Premium (the Ineligible Bondholder Early Submission Amount) by delivering, or arranging to have delivered on their behalf, a valid Ineligible Bondholder Instruction in favour of the Proposal, that is received by the Tender Agent before the Early Tender Deadline and not revoked. The Ineligible Bondholder Early Submission Amount will be paid in the circumstances described in the Tender Offer Memorandum to relevant Ineligible Bondholders on the Settlement Date and on the same basis as if the Bonds in respect of which any such Ineligible Bondholder has validly submitted an Ineligible Bondholder Instruction were permitted to be and in fact were accepted for repurchase by the Company pursuant to the Offer. If the Extraordinary Resolution is passed at the first Meeting and the Company, in its sole discretion, chooses to exercise the Issuer Call immediately, each of the (i) Repurchase Price and Early Redemption Amount, and (ii) any Accrued Interest payment in respect of Bonds repurchased pursuant to the Offer and redeemed pursuant to the Proposal, will be the same. Bond Tender Instructions and Ineligible Bondholder Instructions in favour of the Proposal cannot be revoked after 5.00 p.m., London time, on Tuesday 16th May 2006 (the Revocation Deadline) except in the limited circumstances described in the Tender Offer Memorandum. By tendering Bonds in the Offer or submitting an Ineligible Bondholder Instruction in favour of the Proposal, Bondholders will instruct the Paying Agent to appoint The Bank of New York (the Tender Agent) as their proxy to vote in favour of the Extraordinary Resolution at the Meeting. It will not be possible to validly tender Bonds in the Offer without at the same time giving such instructions to the Paying Agent. The Extraordinary Resolution provides for the terms and conditions of the Bonds to be amended by the insertion of a new provision pursuant to which the Company may redeem all (and not some only) of the Bonds outstanding at any time (the Issuer Call), on the Company giving not less than three business days notice. The redemption amount (the Early Redemption Amount) at which each Bond will be redeemed on such early redemption together with Accrued Interest will be determined in a similar manner to that described in the Tender Offer Memorandum for the determination of the Repurchase Price by reference to the sum of a redemption spread of an identical 65 bps and the Offer Side Benchmark Security Rate.
