Condition 6(e) is deleted and replaced with the following:

"(e)     Redemption at the option of the Noteholders

If, at any time while any of the Notes remains outstanding, a Potential Put
Event occurs and during the Relevant Period, or (other than where the Potential
Put Event is a Category II Restructuring Event) prior to the commencement of the
Relevant Period, an Independent Financial Adviser shall have certified in
writing to the Trustee that such Potential Put Event will not be or is not, in
its opinion, materially prejudicial to the interests of the Noteholders, the
following provisions of this Condition 6(e) shall cease to have any further
effect in relation to such Potential Put Event.

If, at any time while any of the Notes remains outstanding, a Potential Put
Event occurs and an Independent Financial Advisor shall have certified in
writing to the Trustee that such Potential Put Event is, in its opinion,
materially prejudicial to the interests of the Noteholders (a "NEGATIVE
CERTIFICATION"), then, unless at any time the Issuer shall have given a notice
under Condition 6(c), the holder of each Note will, upon the giving of a Put
Event Notice (as defined below), have the option (the "PUT OPTION") to require
the Issuer to redeem or, at the option of the Issuer, purchase (or procure the
purchase of) that Note on the Put Date (as defined below), at its Put Event
Redemption Amount together with (or, where purchased, together with an amount
equal to) interest (if any) accrued to (but excluding) the Put Date.

Any certification by an Independent Financial Adviser as aforesaid as to whether
or not, in its opinion any Potential Put Event is materially prejudicial to the
interests of the Noteholders shall, in the absence of manifest error, be
conclusive and binding on the Trustee, the Issuer, the Guarantor and the
Noteholders.

Promptly upon, and in any event within 14 days after, the Issuer becoming aware
that a Potential Put Event has occurred, the Issuer shall, and at any time upon
the Trustee becoming similarly so aware the Trustee may, and if so requested by
the holders of at least one-quarter in nominal amount of the Notes then
outstanding shall, give notice (a "PUT EVENT NOTICE") to the Noteholders in
accordance with Condition 16 specifying the nature of the Potential Put Event
and the procedure for exercising the Put Option, provided that where the
Potential Put Event is a Category II Restructuring Event the Issuer shall again
give such notice 90 days prior to the Revocation Date (such latter notice, a
"CATEGORY II PUT EVENT NOTICE").

To exercise the Put Option, the holder of a Note must deposit such Note with any
Paying Agent at its specified office, on a day which is a Business Day in the
City of London and in the place of such specified office falling within the
period (the "PUT PERIOD") of (i), in the case where the Put Option is in respect
of an event other than a Category II Restructuring Event, 45 days after that on
