© 2015 Avaya Inc. All rights reserved. 16 Fiscal Q1 2016 Financial Outlook (As Delivered 11/11/15)  Given beginning backlog levels, the impact of currency fluctuations on demand, economic volatility in certain countries and taking into account our current visibility, fiscal first quarter revenue is expected to be in the range of $980 million to $1 billion, 20 million dollars  Compared to Q4 FY ‘15, this is down 2% to up 2%, which is better than the historical sequential range. When compared to the normalized Q1 FY ‘15 revenue of $1,029M, this range implies a decline of 1% - 5%, with a midpoint of 3%, again, better than the historical range.  Adjusted EBITDA for Q1 FY ‘16 should benefit from our progress-to-date on operational improvements and the incremental benefits expected from actions already implemented in fiscal 2015. These will be partially offset by the effect of annual sales conference expenses and the seasonal increased in marketing spend. Taking these into account, and given the forecasted revenue range, we expect Adjusted EBITDA for Q1 FY ‘16 should be in the range of 22% to 25% of revenue.  Total cash requirements for restructuring, pension, interest, cash taxes and capital spending in fiscal 2016 are expected to be $870 million or less with restructuring cash between $90 and $100 million and pension contributions in the range of $150 to $160 million. Fiscal first quarter cash requirements for these items are expected to be $200 million or less.  * On a normalized basis; See slide 18 for Q4 FY’14 normalization calculation NOTE: Avaya does not reiterate guidance or provide any form of mid-quarter update ($M) As Reported In Constant Currency Q1 FY ’15 $1,079 $1,029* Q4 FY ’15 $1,008 $1,002 Revenue Adjusted for Constant Currency As of 11/10/15
