     Notes in circumstances in which Section 21(1) of the FSMA does not apply to
     the Issuer; and

(d)  it has complied and will comply with all applicable provisions of the FSMA
     with respect to anything done by them in relation to such Treasury Notes
     in, from or otherwise involving the United Kingdom.

In respect of any tranche of Treasury Notes which must be redeemed before the

Notes only if the following conditions apply (or the Treasury Notes can
otherwise be issued without contravention of Section 19 of the FSMA):

     (i)  the Dealer represents, warrants and agrees in the terms set out
          hereabove; and
     (ii) the redemption value of each such Treasury Note is not less than
          (pound)100,000 (or an amount of equivalent value denominated wholly or
          partly in a currency other than sterling), and no part of any Treasury
          Note may be transferred unless the redemption value of that part is
          not less than (pound)100,000 (or such an equivalent amount).

requirement of Regulation S. The Dealer and its affiliates also agree that, at
or prior to confirmation of sale of Treasury Notes, it will have sent to each
distributor, dealer or person receiving a selling concession, fee or other
remuneration that purchases Treasury Notes from it during the distribution
compliance period a confirmation or notice to substantially the following
effect:

     "THE SECURITIES COVERED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S.
     SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND MAY NOT BE OFFERED OR
     SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
     PERSONS (I) AS PART OF THEIR DISTRIBUTION AT ANY TIME OR (II) OTHERWISE

     TRANCHE OF WHICH SUCH TREASURY NOTES ARE A PART, EXCEPT IN EITHER CASE IN
     ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT. TERMS USED ABOVE
     HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT."
