Chris, thank you for your tenacity. This is tedious.

Getting those questions answered is helpful but there are two challenges: firstly, the Board were very
clear that we needed something that referred to pre-2010, there is no reference; is that because the
four 'questions' apply before and after 2010? And secondly, the intention was to have a document that
could actually be used eg., in case reviews, circulated to Spmrs. le., for public consumption. How does a
‘board briefing’ respond to that?

We need this tomorrow - particularly if it is only a board briefing. Not next week. And if I don't get that,
then I shall personally escalate. It is a serious undermining of the relationship if it gets to that stage. To
do so, I shall need a chronology of this fiasco (Chris) and a rough estimate of the cost of all work that has
gone their way over the last couple of years, plus any ongoing (Colin). Inc Bol and Fres if they have any
involvement.

And yes, I think we have to let the board know as you indicate.
Martin did you get me the details of the CEO we met a couple of weeks ago?
Thanks,

Paula

All,
I agree with Chris's email.

Deloitte are moving in the right direction but, with the background work they have
done, I think they can turn something around quicker than indicated.

I will follow up with Deloitte tomorrow morning to make sure they can deliver against
Chris's email.

Kind regards, Rod

Subject: FW: Project Zebra

Dear all - following the 2 longish calls that I have had with Deloitte today, they have now
come back in the email below with a revised statement of the "deliverable" that they
are proposing to produce for us. From my read of matter, it looks basically OK, but I
would be interested in feedback (especially from Rod). If the general consensus is that it
is OK, I would propose to ask Alwen to circulate the email to the Board with following
message from me:

Dear all - as was trailed last Friday, Deloitte have been running significantly behind
schedule in the production of their report for the Board. A further draft version of it was
produced on Bank Holiday Monday, but unfortunately (and despite the involvement of
additional partner from the forensic team and verbal assurances to the contrary) the
document produced was both opaque and failed properly to address the "exam
questions" they had been set. The matter was accordingly escalated further within
Deloitte this week and in consequence they have now agreed to re-work the document
into a more succinct "Board Briefing" note, addressing head on the alleged failings in the
system. The email setting out their approach is set out below.

The situation is far from satisfactory and Deloitte are in no doubt that they have
significantly blotted their copy book. They are also suggesting they need until
Wednesday next week to finish the job, which again we are pushing back on, hard. That
said, we felt it important to let the Board know where matters stand currently, and the
reasons for the delay. I should add that there is no suggestion from Deloitte that there is
somehow something "wrong" with the system, or that it is not fit for purpose, rather
our experience is that their internal review partner approach is such that any positive
(and helpful) statements that are made in early drafts are edited out before the draft is
released to us.

lam very sorry to be the bearer of the news of yet another delay.
Regards

Chris

CONFIDENTIAL AND SUBJECT TO LEGAL PRIVILEGE

Chris,

Further to our conversations today, I wanted to confirm the next steps we propose to
take regarding Project Zebra. These seek to create a shorter document for you
(intended for Board circulation) which focusses on certain key (and most relevant)
aspects of our wider work to date.

This "Board Briefing" document will focus on the four questions we agreed by phone,
being:

1. <!--[if !supportLists]--><![endif]-->What comfort can be taken that Horizon only
allows complete transactions (baskets) to be processed?

2. <I--[if !supportLists]--><![endif]-->What comfort can be taken that the
transactions completed in Horizon are ‘digitally sealed’, to protect their integrity
and make it evident if they have been tampered with?

3. <!--[if !supportLists]--><![endif]-->What comfort can be taken that Horizon's
Audit Store maintains and reports from a complete and unchanged record of all
sealed baskets?

4. <!--[if !supportLists]--><![endif]-->What comfort can be taken that Horizon
provides visibility to sub-postmasters of all centrally generated transactions
processed to their Branch ledgers?

For each of the above questions, we will:

2? <!--[if !supportLists]--><![endif]-->List those relevant high level system design
and process control features that we identified in documentation provided to
us;

2? <!--[if !supportLists]--><![endif]-->Describe the facts relating to the extent and
nature of the Assurance Work we have seen;

2 <l--[if !supportLists]--><![endif]-->State what additional work could be
undertaken to increase the level of comfort.

Our comments will be framed in the context and limitations of our work.

We estimate that this deliverable will take until close of play on Wednesday next week
to produce and issue through our review and signoff activities.

Please confirm that these points of focus are an accurate view of the next steps
discussed this afternoon.

Thanks and regards

Gareth
