       Activity: a good operating performance

       2007 was a good year in terms of operating performance:
          Lease signatures up sharply by 15.7%, mainly relets (97,900 m² 
against 84,600 m²);
          Sharp improvement in occupancy rate (89.6% for entire portfolio, 91.4
% for the 3
          predominantly office areas);
          Steady rise in average rent on let portfolio (€160.9 per m² before 
tax and service charges
          compared to €153.2);
          EBITDA margin (EBITDA/rental income + fee income) up from 85.0% to 87.2%.

       Activity was boosted in 2007 by some major new completions in 2006. 
However, net profit amounted to €37.6 million against €43.0 million in 2006 due 
to additional depreciation of €7.0       million on completions and a adverse 
impact of €6.5 million following the temporary withdrawal       of space for 
redevelopment. Net profit does not include the increase in open market value of 
the       portfolio.

             Sharp increase in portfolio value (+ 12.5%) and net asset value (+ 
13%)

             The open market value of the portfolio stood at €3.18 billion (
including transfer taxes), an increase             of 12.5% over 2006, 
including €2.8 billion for the buildings in service. On a like-for-like basis
,             growth in open market value was 6.7%.

             This increase in value is driven mainly by growth in rental income
, with the average net yield             falling from 6.2% to 6%.

             NAV per share amounted to:

                  €130.48 at replacement value (+ 13% over 1 year)
                  €123.42 at liquidation value (+ 13.8% over 1 year)

             Dividend: up 7.2%

             The Board of Directors will recommend a dividend of €4.0 per share 
at the Annual General             Meeting, representing an increase of 7.2% on 
the 2006 dividend.
             Outlook: continued growth of portfolio

             Drawing on its robust business model and healthy fundamentals, 
Silic intends to maintain its pace             of development in 2008 and beyond
, under controlled risk conditions.

             12 projects totalling 197,300 m² have been identified for 
commencement between 2008-2011 at a             projected total cost of €597 
million and projected rental income of €52 million, giving a gross             
return on investment of 8.7%.

             Projected investment for 2008 amounts to €175 million, mainly 
comprising:
                 continued work on 52,000 m² of new buildings started in 2007,
                 launch of two new developments totalling 32,000 m² at Orly-
Rungis and La Défense Nanterre-                 Préfecture.
             The total 84,000 m² for which financing has been secured at a 
maximum cost of 5% will generate             an additional €24 million in 
rental income by 2010.

             In the absence of any major new completions, growth in pre-tax 
ordinary cash flow is expected to
             be in line with 2007.
