- Net asset value at €60.50 per share

- EPRA earnings exceeding forecasts

- Confirmation of interim dividend of €3.94 gross per share for the fiscal year

The Board of Directors of Befimmo SA, Managing Agent of the Befimmo Sicafi, met on
9 November 2011 to prepare the consolidated quarterly financial statements of the Befimmo Sicafi as of 30 September 2011.
We recall that, following the approval of the change in the Befimmo fiscal year by the General Meeting of Shareholders held on 22 June, the current fiscal year, which opened on 1 October 2010, will close on
31 December 2011. Thus, it will exceptionally last 5 quarters. The first twelve months of this fiscal year are comparable to the fiscal year ended 30 September 2010 as published in the Annual Financial Report 2010.

1.1. Change in fair value1 of the property portfolio

The fair value of Befimmo's consolidated portfolio amounts to €1,959.8 million as of
30 September 2011, as compared to a fair value of €1,922.6 million as of 30 September 2010. This value variation incorporates the cost of the renovation works carried out in the portfolio during the four quarters of the fiscal year, the acquisition of the SA Ringcenter, owner of the Pavilion complex, the sale of the Empress Court and Kattendijkdok buildings and of certain floors in the co-ownership building located at chaussée de La Hulpe 177, as well as changes in fair value booked to the income statement.

1 These values are established in application of standard IAS 40 that requires investment property to be booked at "fair value". Fair value is obtained by deducting the average costs for transactions established by independent real-estate experts from the "investment value". It corresponds to (i) 2.5% for property worth more than €2.5 million and (ii) 10% (Flanders) or 12.5% (Wallonia and Brussels) for property worth less than

€2.5 million. The Befimmo portfolio comprises both investment properties and properties held for sale.

EMBARGO - 17 November 2011 - 5.40 PM

The following table shows the fair values of Befimmo's consolidated portfolio, by geographical area.

- Change in floor area between 30 September 2010 and 30 September 2011. Sale of Empress Court and

Kattendijkdok buildings and floors in the Hulpe 177 building, and integration of the Pavilion building.

- The variation matches the change in fair value over (i) the 4 past quarters, i.e. from 1 October 2010 to 30

September 2011 and (ii) the 4th quarter, i.e. from 1 July to 30 September 2011 (excluding investments and

disinvestments).

- The proportion of the portfolio is calculated based on the fair value of the portfolio as of 30 September 2011.

Excluding investments and disinvestments, the unrealized negative change in fair value of the consolidated portfolio was a mere -0.39% or €7.7 million over the fourth quarter of the fiscal year, and amounts to -1.51%, or €30.1 million for the 12 first months of the fiscal year, compared to -1.77% for the same period of the last fiscal year. This small change is in line with published forecasts2.

1.1.1. Overall rental yield

The overall rental yield on current rents of the investment properties (excluding properties that are being constructed or developed for our own account in order to be leased) was 6.59% at
30 September 2011, which is stable compared to 6.60% at the closing of the previous quarter
(30 June 2011) and at the beginning of the fiscal year (30 September 2010). Still on
30 September 2011, the overall rental yield on current rents, increased with the estimated rental value of vacant space, is 6.98% compared to 6.99% as of 30 June 2011 and 6.90% as of 30 September 2010.
Taking into account buildings under construction or developed for our own account in order to be leased, current and potential yields as of 30 September 2011 were 6.42% and 6.87% respectively.

1.1.2. The occupancy rate and the weighted average duration of leases

The occupancy rate3 of the properties available for lease amounts to 94.38% as of 30 September 2011, which is stable since the last quarter (94.44% as of 30 June 2011) compared to 95.53% as the fiscal year opened.
This slight decrease in the occupancy rate since 30 September 2010 resulted from planned departures as well as the completion of renovation works in the Froissart building (± 2.800 m²) located in Brussels in the European district, of which approximately 25% of the lease space is currently let.
The occupancy rate of all investment properties as of 30 September 2011, i.e. including properties that are being constructed or developed for our own account in order to be leased, is 93.49% compared to
94.03% at the beginning of the fiscal year.
As of 30 September 2011, the weighted average duration of current leases is 9.04 years compared to
9.22 years as of 30 June 2011 and 9.13 years as of 30 September 2010.
During the fourth quarter of the 2010/2011 fiscal year, Befimmo signed new leases and lease renewals for an approximate total of 6,500 m², or more than 54,000 m² over the first 12 months of the fiscal year. Some major tenants such as Alpha Crédit or Avnet renewed their leases for several years.

2. R E F I N A N C I N G P R O G R A M A N D H E D G I N G P O L I C Y

The Company pursues its refinancing program and implemented, in October 2011, two new financing plans to cover the portion of the 2006 syndicated loan maturing in March 2012 for a total amount of
€130 million.
This concerns a fixed rate loan of €44 million corresponding to the assignment of future (excluding indexation) rents on a Befimmo building (average weighted duration of 6.8 years) and a bilateral credit line maturing in March 2017 for an amount of €100 million.
As a reminder, in April 2011, Befimmo issued bonds with a maturity of 6 years for an amount of
€162 million, which was the first part of its refinancing program for a total of €400 million scheduled in
2011/2012.
As of 30 September 2011, the average duration of Befimmo's debt is
3.79 years. As of the same date, Befimmo has committed financing for a total amount of
€1,037 million, drawn up to €839 million. Its average financing cost (including margin and hedging costs) amounts to 3.36% over a period of 12 months ending on
30 September 2011.

3 Occupancy rate: current rent (including space already let but where the lease has yet to begin) / (current rent

+ estimated rental value of vacant space).

To reduce its financing costs, Befimmo implemented a commercial paper program for an amount up to a maximum of €400 million. As of 30 September 2011, this program had been used for €291.5 million. This program includes back-up lines composed of the various financing lines implemented.
During the next few months, the Company will continue its refinancing and source diversifying program in order to meet its March and June 2013 loan maturity dates, or a total amount of approximately €500 million. It also intends to secure its financing for terms as long as possible.
On 5 October 2011, the Standard & Poor's credit-rating agency confirmed the BBB/outlook stable rating for Befimmo's long-term debt, and the A-2 rating for the short-term debt.
In the course of the last few months, Befimmo has extended its portfolio of interest rate risk hedging instruments and prolonged the average weighted duration of the instruments. The hedging ratio exceeds 80% until the third quarter of 2013, 70% until the second quarter of 2014, 60% until the fourth quarter of 2014, and 30% until the second quarter of 2016.

5.1. Events modifying the Company's floor area

The Company's real estate floor area was modified during the first 12 months of the current fiscal year, primarily following the sales of the Kattendijkdok (January 2011) and Empress Court (March 2011) buildings and the sale of floors in the co-ownership building located chaussée de La Hulpe 177 in Brussels (June 2011), and the acquisition of Ringcenter SA, owner of the Pavilion complex (February
2011).
The comparison of the first twelve months of the 2010/2011 fiscal year with the 12 months of the
2009/2010 fiscal year is therefore affected by the impact of this floor area modification.

5 This is the internal rate of return calculated over the last 12 months, taking into account the dividend of €3.90

per share (gross) distributed in December 2010.

5.2. Analysis of the result

Net rental income is slightly higher (+0.7%) than the net income recorded over the first four quarters of the previous fiscal year. At a constant floor area, this result is slightly lower -0.9%. This decrease, primarily resulting from the end of the income guarantee for the Axento building in Luxembourg and the impact of renegotiating certain leases, is offset by the contribution of the Pavilion complex since its integration into Befimmo's portfolio in February 2011, and by rent indexation.

Net real-estate charges decreased (-27.5%) compared to the previous fiscal year. This decrease essentially results from non-recurring items, notably compensations associated with departing tenants.

The result from the sale of investment properties amounts to €15.0 million. This amount was generated by sales completed in early 2011 (Empress Court building in Brussels, Kattendijkdok building in Antwerp, and sale of floors in the co-ownership building located at chaussée de La Hulpe 177 in Brussels) and is higher than previously announced.

The financial result (excluding the IAS 39 result) amounts to -€26.3 million compared to -€22.8 million one year earlier. This evolution in the financial result is primarily explained by a rise in the interest rates on the short term, but also by a small increase in the average debt of the Company.

The change in fair value of financial instruments is +€5.4 million compared to -€3.8 million one year earlier. Due to the large volatility of the interest rate curve, the recorded variations during the first 6 months amounted to +€17.4 million compared to -€11.9 million during the 6 following months.

The change in fair value of investment properties amounts to -€30.1 million (or -1.51%) compared to

-€34.6 million (or -1.77%) one year earlier.
These factors result in a net result (group share) of €63.9 million (or €3.80/share), compared with
€46.7 million (or €2.78/share) one year earlier.
EPRA earnings for the first twelve months of the fiscal year were down (-12.6%) compared to last fiscal year. This decline is explained by the non-recurring result, recorded last year, of the termination of the leasehold granted on Block II of the WTC (+€7.2 million, or €6.5 million group share). In comparison with previously published forecasts6, EPRA earnings are, however, rising (+6.5%) primarily as a result of the contribution of the Pavilion building (February 2011), of an indexation of leases higher than forecasted and of several non-recurring operational economies.

6. O U T L O O K

Following the change in the Befimmo fiscal year decided by the General Meeting of Shareholders on
22 June, and as previously announced7, the Board of Directors of the Managing Agent of the Sicafi has
decided to distribute an interim dividend for the fiscal year, which confirms the neutral effect of the change of the fiscal year for the shareholders.
This interim dividend amounts to €3.9412 gross per share (amount rounded to 4 decimals), or €3.3500 net per share, i.e. the dividend amount foreseen for the 2010/2011 fiscal year (4 quarters8).
In April 2012, the agenda of the Ordinary General Meeting of Shareholders at which the accounts for the 2010/2011 fiscal year are to be approved, will include a proposition to distribute, as the case may be, a final dividend (currently estimated at €0.99 gross per share) for the 2010/2011 fiscal year, based on the current net result for the fifth quarter of said fiscal year.
