                           REVERSE OF CAPITAL SECURITY

         Distributions  payable on each Capital  Security  will be payable at an
annual rate equal to 8.08063%  beginning on (and including) the date of original
issuance and ending on (but excluding) the Distribution Payment Date in December
2007  and at an  annual  rate  for  each  successive  period  beginning  on (and
including) the  Distribution  Payment Date in December 2007, and each succeeding
Distribution  Payment Date, and ending on (but  excluding)  the next  succeeding
Distribution  Payment  Date  (each a  "Distribution  Period"),  equal to 3-Month
LIBOR, determined as described below, plus 2.85% (the "Coupon Rate"), applied to
the stated liquidation amount of $1,000.00 per Capital Security, such rate being
the rate of interest  payable on the Debentures to be held by the  Institutional
Trustee.   Distributions  in  arrears  will  bear  interest  thereon  compounded
quarterly at the Distribution  Rate (to the extent permitted by applicable law).
The term "Distributions" as used herein includes cash distributions and any such
compounded  distributions unless otherwise noted. A Distribution is payable only
to the extent that  payments are made in respect of the  Debentures  held by the
Institutional  Trustee  and to the extent the  Institutional  Trustee  has funds
available therefor. As used herein,  "Determination Date" means the date that is
two London  Banking Days (i.e.,  a business day in which dealings in deposits in
U.S.  dollars are  transacted  in the London  interbank  market)  preceding  the
commencement of the relevant Distribution Period. The amount of the Distribution
payable  for  any  Distribution  Period  will  be  calculated  by  applying  the
Distribution  Rate  to  the  stated   liquidation   amount  outstanding  at  the
commencement of the Distribution  Period and multiplying each such number by the
actual number of days in the Distribution Period concerned divided by 360.

         "3-Month  LIBOR" as used  herein,  means the London  interbank  offered
interest rate for three-month  U.S. dollar deposits  determined by the Debenture
Trustee  in the  following  order  of  priority:  (i) the rate  (expressed  as a
percentage per annum) for U.S.  dollar  deposits  having a three-month  maturity
that  appears on Reuters  Page  LIBOR01  as of 11:00 a.m.  (London  time) on the
related  Determination Date ("Reuters Page LIBOR01" means the display designated
as "LIBOR01"  on Reuters or such other page as may replace  Reuters Page LIBOR01
on that  service or such other  service or services as may be  nominated  by the
British  Bankers'  Association  as the  information  vendor  for the  purpose of
displaying  London interbank  offered rates for U.S. dollar  deposits);  (ii) if
such rate cannot be identified on the related  Determination Date, the Debenture
Trustee will request the principal  London  offices of four leading banks in the
London interbank market to provide such banks' offered quotations  (expressed as
percentages  per annum) to prime banks in the London  interbank  market for U.S.
dollar deposits having a three-month  maturity as of 11:00 a.m. (London time) on
such Determination Date. If at least two quotations are provided,  3-Month LIBOR
will be the  arithmetic  mean of such  quotations;  (iii) if fewer than two such
quotations are provided as requested in clause (ii) above, the Debenture Trustee
will  request  four  major New York City banks to provide  such  banks'  offered
quotations  (expressed as percentages  per annum) to leading  European banks for
loans in U.S. dollars as of 11:00 a.m. (London time) on such Determination Date.
If at  least  two  such  quotations  are  provided,  3-Month  LIBOR  will be the
arithmetic mean of such  quotations;  and (iv) if fewer than two such quotations
are provided as requested in clause (iii) above, 3-Month LIBOR will be a 3-Month
LIBOR determined with respect to the Distribution  Period immediately  preceding
such current  Distribution Period. If the rate for U.S. dollar deposits having a
three-month  maturity that initially appears on Reuters Page LIBOR01 as of 11:00
a.m.  (London  time) on the  related  Determination  Date is  superseded  on the
Reuters  Page LIBOR01 by a corrected  rate by 12:00 noon  (London  time) on such
Determination  Date, then the corrected rate as so substituted on the applicable
page will be the applicable 3-Month LIBOR for such Determination Date.

         The Distribution  Rate for any  Distribution  Period will at no time be
higher than the maximum  rate then  permitted by New York law as the same may be
modified by United States law.

         All  percentages   resulting  from  any  calculations  on  the  Capital
Securities will be rounded, if necessary,  to the nearest one hundred-thousandth
of a percentage  point,  with five  one-millionths of a percentage point rounded
upward (e.g.,  9.876545% (or .09876545) being rounded to 9.87655% (or .0987655),
and all  dollar  amounts  used in or  resulting  from such  calculation  will be
rounded to the nearest cent (with one-half cent being rounded upward)).

         Except as  otherwise  described  below,  Distributions  on the  Capital
Securities  will be cumulative,  will accrue from the date of original  issuance
and will be payable  quarterly in arrears on March 15, June 15, September 15 and
December 15 of each year or if any such day is not a Business Day, then the next
succeeding Business Day (each such day, a "Distribution Payment Date") (it being
understood that interest accrues for any such non-Business  Day),  commencing on
the  Distribution  Payment Date in December 2007.  The Debenture  Issuer has the
right under the Indenture to defer  payments of interest on the  Debentures,  so
long as no  Acceleration  Event of Default has  occurred and is  continuing,  by
extending the interest payment period on the Debentures for up to 20 consecutive
quarterly periods (each an "Extension Period") at any time and from time to time
on the  Debentures,  subject to the  conditions  described  below,  during which
Extension  Period no interest  shall be due and  payable.  During any  Extension
Period, interest will continue to accrue on the Debentures, and interest on such
accrued interest will accrue at an annual rate equal to the Distribution Rate in
effect for each such Extension Period,  compounded  quarterly from the date such
interest  would have been payable were it not for the Extension  Period,  to the
extent  permitted  by law (such  interest  referred  to  herein  as  "Additional
Interest").  No  Extension  Period may end on a date  other than a  Distribution
Payment  Date. At the end of any such  Extension  Period,  the Debenture  Issuer
shall pay all interest then accrued and unpaid on the Debentures  (together with
Additional Interest thereon);  provided,  however,  that no Extension Period may
                               --------   -------
extend  beyond the Maturity  Date.  Prior to the  termination  of any  Extension
Period, the Debenture Issuer may further extend such period,  provided that such
period  together  with all such  previous  and  further  consecutive  extensions
thereof shall not exceed 20 consecutive  quarterly periods, or extend beyond the
Maturity Date. Upon the termination of any Extension Period and upon the payment
of all accrued and unpaid interest and Additional Interest, the Debenture Issuer
may commence a new Extension Period, subject to the foregoing  requirements.  No
interest or  Additional  Interest  shall be due and payable  during an Extension
Period,  except at the end thereof,  but each installment of interest that would
otherwise  have been due and payable  during such  Extension  Period  shall bear
Additional Interest.  During any Extension Period,  Distributions on the Capital
Securities  shall be deferred for a period  equal to the  Extension  Period.  If
Distributions are deferred, the Distributions due shall be paid on the date that
the related  Extension Period  terminates,  to Holders of the Securities as they
appear on the books and  records  of the Trust on the  record  date  immediately
preceding such date.  Distributions  on the Securities must be paid on the dates
payable  (after giving  effect to any  Extension  Period) to the extent that the
Trust has funds available for the payment of such  distributions in the Property
Account of the Trust.  The  Trust's  funds  available  for  Distribution  to the
Holders  of the  Securities  will be  limited  to  payments  received  from  the
Debenture  Issuer.  The payment of Distributions out of moneys held by the Trust
is guaranteed by the Guarantor pursuant to the Guarantee.

         The  Capital   Securities  shall  be  redeemable  as  provided  in  the
Declaration.
