Additional Notes to the Investor Reports

The Overcollateralisation test will be breached on any distribution date where
the aggregate current balance of mortgage loans on such distribution date is
less than an amount equal to the product of 1.05 and the principal amount
outstanding of all notes of all issuers on such distribution date. The
principal amount outstanding of such notes will be calculated on a straight
line basis by applying the appropriate constant payment rate applicable to
each series of notes on a monthly, rather than quarterly, basis.

A non asset trigger event will occur if the current seller share is equal to
or less the minimum seller share for two consecutive months. The one month
cure period will now allow the seller to substitute new loans into the trust
to meet the minimum seller requirement.

The notes may be redeemed at the option of the issuer if on the payment date
falling on or after July 2008, the New Basel Capital Accord has been
implemented in the United Kingdom

A arrears trigger event will occur if the outstanding principal balance of 90+
day arrears in the trust exceed 2%. In the event of a arrears trigger the
Granite Mortgages 04-2 issuer reserve fund will step up to 1.415%. This
trigger event is curable.

A issuer non call trigger event will occur if any of the issuers are not
called on their step up and call dates. In the event of a issuer non call
trigger the Granite Mortgages 04-2 issuer reserve fund target will step up by
0.275% and the funding reserve target will step up by 0.10%.

A accelerated controlled amortisation trigger will occur if any of the issuers
are not called on their step up and call dates. In the event of a accelerated
controlled amortisation trigger all Granite Mortgages 04-2 tranches become
pass through securities.
