lan,
Further to my email below, here is the high level outline for how we would like to repackage the draft Report.
Please give me a call when you get a chance to get this moving asap.
Thanks, Rod

- Detailed description of aspects of the system the subject of review.
Analysis/assessment of assurance work

write once/ read many times audit store 3) data centre and the inability for transactions unilaterally to be created within
it
- Cover any other aspects of Horizon the testing of which is necessary to provide confidence in Horizon by reference to

Gareth, lan,
We have discussed your draft Report with Linklaters with a view to repackaging/supplementing it for use in
connection with the allegations made by Applicants to the Mediation Scheme. I have copied Jonathan Swil from
Linklaters to this email.
We are under time pressure to deliver a repackaged report to our Board. To progress matters, the next steps are:
1. Linklaters are going to sketch an outline structure for the repackaged report. That will be delivered by close
of play today;
2. Deloitte need to reflect that outline in a discussion document (e.g. working draft) prepared using the work
done for the current draft Report;
3. We meet on Monday 2 June 2014 to advance the production of the repackaged report.
lan —can you please confirm your availability for a meeting on Monday (I have cc’ed your EA). We can discuss over
the phone what the discussion document could look like once we have Linklaters’ outline.
Jonathan — can you please confirm availability for a meeting on Monday, and that we can meet at your offices (One
Silk Street, London EC2Y 8HQ).
