Pete,

I will obviously need the ‘transaction logs' referred to in the letter (I assume this is a messagestore extract from the
archives?). Are they available somewhere?

Dear Brian,

The P.O have considered the costs involved and have now authorised you to proceed with this task.

Please can I see the draft report before it is finalised and let me know if I can assist by supplying any further information
to you. What we'd like at the end is a reasoned analysis explaining whether the comments in Mr Castleton's solicitors
letter (attached) are wrong or right and if so, why. We may well have to produce it to the Court and rely on it, so it also
needs to make sense to a judge who might not be IT literate and who doesn't know anything about Horizon.

I look forward to hearing from you.

Kind regards.

Stephen Dilley

Stephen Dilley (representing the Post Office) is asking if it is possible that someone undertakes an analysis of the figures
recorded on the transaction logs supplied by Fujitsu against the figures on the completed cash account for CAP 42
(08/01/04 - 14/01/04). It appears that the solicitor's for Castleton are saying that they've compared the transaction logs
with the cash accounts for week 42 themselves (just for an initial

analysis) and that they don't match. They conclude that Horizon is therefore only recording half the transaction. I've
attached below the letter dated 25th July from Castleton's solicitors which outlines details of the anomalies.

(See attached file: eCopy scanned document.pdf)

Given this is a 'test' case and that the integrity of the Horizon system is being challenged, my own opinion is that this
exercise should be completed by an ‘expert' from Fujitsu. However it will obviously be extremely time consuming as all
the figures recorded will need to be methodically and carefully analysed. It is also important that we complete the
analysis and respond formally to the points raised as soon as possible, therefore my first question is :

1/\s this an exercise that Fujitsu could undertake, possibly by Gareth perhaps, who would presumably have a thorough
understanding of the figures recorded on both the transaction logs and the figures on an office cash account ?

2/ \f the answer is yes, how soon could this exercise be performed and a formal response prepared ?

3/ Will there be a cost involved and if so how much ?

I would appreciate an early response

Regards

Graham
