On 26 June 2013 Origin advised an amendment had been made to the terms and conditions of the Origin Energy Subordinated Notes. The definition of Testing Date for the Leverage Ratio calculation used in the determination of Mandatory deferral of Interest Payments (clause 3.6 of the terms and conditions) was amended such that the Leverage Ratio is not tested and reported from 30 June 2013 to 30 June 2016 (inclusive). For more information go to: www.originenergy.com.au/news/article/asxmedia-releases/1498

The Interest Cover Ratio will continue to be tested every six months to determine whether or not a Mandatory Deferral Event exists. A Mandatory Deferral Event will commence during the period to 30 June 2016 (inclusive) if Origin’s Interest Cover Ratio in relation to a Testing Date

1 As derived from Origin’s Financial Statements released to the ASX on 20 August 2015 and 21 August 2014.

is less than the Minimum Level (being 3.5 times). A Mandatory Deferral Event will continue until Origin’s Interest Cover Ratio in relation to a Testing Date is at or above the Minimum Level.

For the period after 30 June 2016, a Mandatory Deferral Event will commence if either Origin’s Interest Cover ratio in relation to a Testing Date is less than the Minimum Level, or if Origin’s Leverage Ratio in relation to two consecutive Testing Dates is above the Maximum Level (being 4.0 times). A Mandatory Deferral Event will continue until Origin’s Interest Cover Ratio in relation to a Testing Date is at or above the Minimum Level and its Leverage Ratio has not been above the Maximum Level in relation to two consecutive Testing Dates.

As at 30 June 2015, no Mandatory Deferral Event had commenced.
