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 an arrears trigger the
Granite Mortgages 04-2 issuer reserve fund will step up to 1.415%, the Granite
04-3 issuer reserve fund will step up to 1.38% and the Funding 2 reserve fund
required amount increases by (GBP)8 million. 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 an issuer non call
trigger the Granite Mortgages 04-2 issuer reserve fund target will step up by
0.275%, the Granite Mortgages 04-3 issuer reserve fund target by 0.27%, the
funding reserve target will step up by 0.10% and the funding 2 reserve fund
required amount increases by (GBP)8 million. If the breach is rectified only
the funding 2 reserve fund required amount will reduce to its original target.

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 an accelerated
controlled amortisation trigger all Granite Mortgages 04-2 & 04-3 tranches
become pass through securities.

Excess spread is defined, in any month as cash received from Granite Mortgages
Trust in that month plus bank interest due to Funding and Funding 2 and the
Issuer/Master Issuer in that month plus/minus amounts due under the basis rate
swap agreement less bond interestdue for floating GBP bonds and amounts due to
swap counterparties for currency bonds and Fixed Rate GBP bonds.
