This presentation contains forward-looking statements about Mobistar, in particular for 2010. Although Mobistar believes these statements are based on reasonable assumptions, these forward-looking statements are subject to numerous risks and uncertainties, including matters not yet known to us or not currently considered material by us, and there can be no assurance that anticipated events will occur or that the objectives set out will actually be achieved. Important factors that could cause actual results to differ materially from the results anticipated in the forward-looking statements include, among others, the effectiveness of the mobility centric operator strategy including the success and market acceptance of the mobile voice and date abundance plans, the Mobistar brand and other strategic, operating and financial initiatives, Mobistar’s ability to adapt to the ongoing transformation of the telecommunications industry, regulatory developments and constraints and the outcome of legal proceedings, risks and uncertainties related to business activity.

Cost

The increase in cash expenses is mainly driven by interconnection, network roll-out, handset sales and MES Q2 integration (19,7 M EUR)

Orange Luxembourg• More interconnect costs linked to overall traffic increase and additional incoming

revenues and carrier transit

• More handsets costs in correlation with the handsets sales increase

Non-headcount cost• Higher dealer remuneration driven by postpaid volumes & contract

extensions• Exceptional expenses related to MES S.A., cost associated move to new

building and strategic partnership FT• Increase in Advertising & Promotion• Optimization of costs following Mobistar’s transformation program • Occupancy, consultancy and maintenance expenses related to MES

Headcount costs• Mobistar’s headcount remains flat. The investment in new lines of

business and owned shops is fully financed by efficiency gains• Negative indexation of Jan 1, 2010• MES 130 FTE impact amounts to 1,8 Mio EUR

Interconnect and other costs of sales

• Increase of Interconnect costs +9% YoY (vs +14% for incoming revenues) mainly driven by SMS abundance retail offers partially compensated by customer roaming regulation.
