This announcement is for informational purposes only, does not purport to be complete and does not constitute an offer, or any solicitation of any offer, to buy or subscribe for any securities. No tender offer for the Cofinimmo Shares has commenced at this time and article 15 of the Takeover Decree does not apply to this announcement. Whether, when and at what conditions the Proposed Exchange Offer will be made, is dependent on a number of factors, including general market conditions and the further evolution of the financial markets. Any offer will be made only in compliance with the Takeover Act and the Takeover Decree, and by means of a prospectus approved by the FSMA further to the Takeover Decree and subject to the terms and conditions to be set out therein.

PRESS RELEASE

This press release does not constitute an offer to acquire, buy, subscribe for, sell or exchange securities (or the solicitation of an offer to acquire, buy, subscribe for, sell or exchange securities) in or from the United States, Australia, Canada, Hong Kong, Japan, New Zealand, Switzerland, South Africa, the United Kingdom or any other jurisdiction where it would constitute a violation of the laws of such jurisdiction, and no such offer (or solicitation) may be made in any such jurisdiction. Any failure to comply with this restriction may constitute a violation of US, Australian, Canadian, Hong Kong, Japanese, South African, Swiss, UK, New Zealand or other applicable securities law. Any persons reading this announcement should inform themselves of and observe any such restrictions. The securities discussed herein have not been, and will not be, registered under the US Securities Act of 1933, as amended (the "US Securities Act") or the securities laws of any state of the United States, and may not be offered, sold or delivered, directly or indirectly, in or into the United States without registration, except pursuant to an applicable exemption from, or in a transaction not subject to, the registration requirements of the US Securities Act and in compliance with any applicable state and other securities laws of the United States. There will be no public offering of securities in the United States.

In the United Kingdom, this press release is only being made to and directed at persons (i) who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (the "Order"), (ii) falling within article 49(2)(a) to (d) ("high net worth companies, unincorporated associations, etc.") of the Order, or (iii) to whom it may otherwise lawfully be communicated (all such persons together being referred to as "Relevant Persons"). Any investment or investment activity to which this press relates will be available only to, and will be engaged in only with, Relevant Persons. Any person who is not a Relevant Person should not act or rely on this press release or any of its contents.

The Proposed Exchange Offer, if and when made, will be made for all of the issued and outstanding shares of Cofinimmo, which is a public regulated real estate company in the form of a public limited liability company under Belgian law, and will be subject to Belgian disclosure and procedural requirements. The Proposed Exchange Offer will be made to Cofinimmo shareholders in the United States in compliance with the applicable US tender offer rules under the US Securities Exchange Act of 1934, as amended (the "US Exchange Act"), and otherwise in accordance with the requirements of Belgian law. Accordingly, the Proposed Exchange Offer will be subject to disclosure and other procedural requirements, including with respect to withdrawal rights, the proposed timetable, settlement procedures and timing of payments that are different from those applicable under US domestic tender offer law and practice. The financial information included in this press release or to be included in the prospectus for the Proposed Exchange Offer has been prepared in accordance with applicable accounting standards in Belgium, and will not have been prepared in accordance with US GAAP, or derived therefrom, and may therefore differ from, and not be comparable with, financial information of US companies.

Aedifica and Cofinimmo and their respective affiliates or brokers (acting as agents for Aedifica, Cofinimmo or their affiliates, as applicable) may from time to time, and other than pursuant to the Proposed Exchange Offer, directly or indirectly, purchase, or arrange to purchase outside the United States, shares in Cofinimmo or any securities that are convertible into, exchangeable for or exercisable for such shares before or during the period in which the Proposed Exchange Offer remains open for acceptance, to the extent permitted by, and in compliance with, Rule 14e-5 under the US Exchange Act. Any such purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. To the extent required in Belgium, any information about such purchases will be made public in Belgium in the manner required by Belgian law. To the extent information about such purchases or arrangements to purchase is made public in Belgium, such information will be disclosed by means of a press release or other means reasonably calculated to inform persons in the United States of such information. In addition, affiliates of the financial adviser to Aedifica may engage in ordinary course trading activities in securities of Cofinimmo, which may include purchases or arrangements to purchase such securities.

PRESS RELEASE

Neither the US Securities and Exchange Commission nor any US state securities commission has approved or disapproved of the Proposed Exchange Offer, passed upon the merits or fairness of the Proposed Exchange Offer, or determined if this press release, the prospectus or other Proposed Exchange Offer documents are accurate or complete.

The Proposed Exchange Offer, if consummated, may have consequences under US federal income tax and applicable US state and local, as well as non-US, tax laws for Cofinimmo shareholders. Each Cofinimmo shareholder is urged to consult his or her independent professional adviser regarding the tax consequences of the Proposed Exchange Offer.

It may not be possible for Cofinimmo shareholders in the United States to effect service of process within the United States upon Aedifica, Cofinimmo, or their respective officers or directors, some or all of which may reside outside the United States, or to enforce against any of them judgments of the United States courts predicated upon the civil liability provisions of the federal securities laws of the United States or other US law. It may not be possible to bring an action against Aedifica, Cofinimmo, or their respective officers or directors (as applicable), in a non-US court for violations of US law, including the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgement. In addition, it may be difficult to enforce in Belgium original actions, or actions for the enforcement of judgments of US courts, based on the civil liability provisions of the US federal securities laws.

The securities mentioned herein may not be publicly offered, directly or indirectly, in Switzerland within the meaning of the Swiss Financial Services Act ("FinSA") (unless in circumstances falling within article 36 of the FinSA), and no application has been made or will be made to admit the securities to trading on any trading venue (i.e., exchange or multilateral trading facility) in Switzerland. Neither this press release nor the prospectus or any other offering or marketing material relating to the Exchange Offer or the securities constitutes a prospectus within the meaning of the FinSA, and neither this press release nor the prospectus or any other offering or marketing material relating to the Exchange Offer or the securities may be publicly distributed or otherwise made publicly available in Switzerland.

Neither this press release nor the prospectus or any other offering or marketing material relating to the Exchange Offer or the securities has been or will be filed with or approved by any Swiss regulatory authority. In particular, the prospectus will not be reviewed or approved by a Swiss reviewing body (Prüfstelle) pursuant to article 51 of the FinSA and does not comply with the disclosure requirements applicable to a prospectus within the meaning of article 35 of the FinSA.

This announcement is not for release, publication or distribution, in whole or in part, in or into, directly or indirectly, any jurisdiction in which such release, publication or distribution would be unlawful.
