PRESS RELEASE

Paris, January 14, 2013

Activity for 2012 An organic growth in invoiced rents of +4.3% and stable rental revenues despite assets disposals 8 'Esprit Voisin' projects completed over the year Launch of the 'Foncière Commerçante'1 model Euro 302 million of assets sold, around Euro 120 million of assets sales at an advanced negociation stage and Euro 60 million of additional assets sales in progress A portfolio refocused on assets benefiting from a size and a market positioning suited to the 'Foncière Commerçante' model

The fourth quarter of 2012 puts an end to an extremely active year for Mercialys proving once again the robustness and resilience of Mercialys business model, with rental revenues driven by a strong organic growth and the completions of 'Esprit Voisin' projects.
The implementation of the new strategy of 'Foncière Commerçante' kept on going over the year. The first pilot tests were launched in 8 shopping centers during the second half of the year and we started to refocus our portfolio on assets with a size and a market positioning in line with our strategy of 'Foncière Commerçante'.

I. Rental revenues and rental management indicators

2012 full year rental revenues remained almost stable compared with 2011 at Euro 160.4 million taking into account the impact of the assets disposals.

Invoiced rents as of December 31, 2012 amounted Euro 152.5 million, a slight decrease of -0.6% over 2012.
2012 was characterized by:
- a steady organic growth in invoiced rents: +4.3 points (including indexation 2 : +2.0 points);
- the impact of the completion of 'Esprit Voisin' development projects and the inclusion in the portfolio of 2011 and
2012 acquisitions: impact of +3.9 points on growth in invoiced rents;
- the effect of asset sales carried out in late 20113 and the asset sales carried out in 2012, reducing our rental base: -7,6 points.
The change in invoiced rents during the year was also influenced by non-recurring items, mainly relating to base effects (positive non-recurring items recognized in 2011) and the strategic vacancy relating to on-going redevelopment programs, with a negative impact on growth in invoiced rents at end-2012 (-1.2 point).
Following a record year in 2011, the renewals and reletting activity maintained a strong pace in 2012 with 209 leases signed (compared with 255 in 2011), representing a growth in the annualized rental base of respectively +23% for renewals and +49%4 for relets.
Thanks to the implementation of a dedicated team in 2010, the Speciality Leasing activity also continued to post strong growth: invoiced rents were up +9.1% in 2012 at Euro 4.3 million (compared with Euro 3.9 million invoiced in
2011 and Euro 3.4 million invoiced in 2010).
Lease rights and despecialization indemnities received as of December 31, 20125 amounted to Euro 4.9 million, compared with Euro 10.2 million in 2011, breaking down as follows:

- Euro 3.0 million in lease rights relating to ordinary reletting activities and despecialization indemnities (compared with Euro 4.8 million as of December 31, 2011),

- Euro 1.9 million in lease rights relating primarily to the letting of the Quimper, Fréjus and Istres extension/
redevelopment programs completed in 2012 (compared with Euro 5.4 million as of December 31, 2011).
2011 benefited from significant extensions completions (Geispolsheim, Ajaccio, Marseille La Valentine, Annemasse, Auxerre and Villefranche) that generated an exceptional amount of lease rights received.
After the impact of deferrals required under IFRS (deferring of lease rights over the firm period of the lease), lease rights and despecialization indemnities recognized as rental revenues as of December 31, 2012 increased by +3.4% to Euro 7.9 million (compared with Euro 7.6 million as of December 31, 2011), as a result of significant lease rights received both in 2010 and 2011.

Rental management indicators as of December 31, 2012 remained at a good level

> The current vacancy rate 6 as of December 31, 2012 remained stable at 2.4% compared to June 30, 2012;
> 2012 recovery rate over 12 months as of December 31, 2012 remained satisfactory at 97.7% (vs 97.8% as of June,
2012 and 98.3% as of December 31, 2011);
> The number of tenants under liquidation remained stable and at a marginal level.

2 In 2012, for the majority of leases, rents were indexed either to the change in the construction cost index (CCI) or to the change in the retail rent index (ILC)

between the second quarter of 2010 and the second quarter of 2011 (respectively +5.01% and +2.56%)

II. Completion of 'Esprit Voisin' projects and assets disposals 8 projects completed in 2012 including 4 in Q42012

During Q4 2012, completions of Esprit Voisin projects kept on going at a steady pace:
- The sites of Montauban and Istres benefited from a renovation and an extension of the shopping mall that increase their commercial position.
- In Narbonne, an H&M store opened on an area acquired from the anchored hypermarket.
- Finally, in November 2012, Mercialys completed the extension of Bordeaux-Pessac shopping center. As a reminder, Mercialys and Union Investment, a fund manager highly active in the real estate market, created in
2011 an OPCI fund designed to invest in mature retail properties. The fund is 80%-owned by Union
Investment and 20% by Mercialys. Mercialys is in charge of asset management and letting of premises. In
2011, the fund acquired its first asset in Bordeaux-Pessac comprising a shopping center and a retail park. The extension developed under the 'Esprit Voisin' concept was sold to this OPCI fund on an off-plan basis.
Thus, a total of 66 new stores opened during Q42012 representing a full-year rental value of Euro 4.4 million (including Euro 2.5 million for Bordeaux-Pessac extension) and a newly created, redeveloped and/or renovated GLA of 38,300sqm.
In addition, a retail park developed by the Casino development teams opened in front of our existing shopping center at Fontaine- les-Dijon, reinforcing the position of this site.
4 projects had already been completed during the first-half of 2012 including:
- 1 extension developed on areas acquired from the anchored hypermarket at the site of Agen Boé;
- 2 extensions of the existing shopping mall at the sites of Fréjus and Rodez;
- 1 redevelopment of a former Castorama store as new shops at the site of Quimper.
In total, 117 new retailers opened during 2012, representing a full-year rental value of Euro 8.2 million (including Euro 2.5 million for Bordeaux-Pessac extension) and newly created, redeveloped and/or renovated GLA of 68,000 m².
At the same time, 7 shopping centers were renovated in 2012 under the 'Esprit Voisin' concept.

Euro 302 million of assets sold

The asset rotation policy initiated by the Company in 2010 continued in 2012.
Thus, Mercialys sold 21 assets during 2012 representing an amount of Euro 232 million including transfer taxes at an average capitalization rate including transfer taxes of 6.25%. Furthermore, Mercialys accepted binding acquisition
offers for 20 additional assets representing an amount of Euro 69 million including transfer taxes.
Recorded sales comprise 14 neighborhood shopping centers (Avignon Cap Sud, Geispolsheim, Larmor, Les Sables d'Olonne, Limoges, Lons le Saunier, Montpellier Gange, St André de Cubzac, St Etienne La Ricamarie, Torcy Monchanin, Toulouse Basso Combo, Troyes Barberey, Villenave d'Ornon and Villefranche), 1 extension sold on an off-plan basis (Bordeaux-Pessac) and 6 standalone lots (service outlet, cafeterias, offices).
Rental income from these properties, excluding the extension of Bordeaux-Pessac, amounts to Euro 12.0 million on a full year basis.
The accepted binding acquisition offers comprise Dijon Chenôve site, Brive downtown site, and 18 additional isolated assets.
In addition to those Euro 302 million of assets disposals, an amount of around Euro 120 million of assets sales is at an advanced negociation stage, and Euro 60 million of additional assets sales are in progress.
