                              By:_____________________________
                                 Authorized Signatory

                              REVERSE OF SECURITY

     Distributions on each Capital Security will be payable at a fixed rate per
annum of [_____]% (the "Coupon Rate") of the liquidation amount of $  per
Capital Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. Distributions in arrears for more than one
quarterly period will bear interest thereon compounded quarterly at the Coupon
Rate (to the extent permitted by applicable law). The term "Distributions," as
used herein, includes such cash distributions and any and all such interest, if
any, payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has funds legally available
therefor.

          Distributions on the Capital Securities will be cumulative, will
accumulate from the most recent date to which Distributions have been paid or,
if no Distributions have been paid, from [_________], 1999 and will be payable
quarterly in arrears, on         ,        ,              and             of each
year, commencing [_________], 1999, except as otherwise described below.
Distributions will be computed on the basis of a 360-day year consisting of
twelve 30-day months. As long as no Event of Default has occurred and is
continuing under the Indenture, the Debenture Issuer has the right under the
Indenture to defer payments of interest by extending the interest payment period
at any time and from time to time on the Debentures for a period not exceeding
20 consecutive calendar quarterly periods, including the first such quarterly
period during such extension period (each an "Extension Period"), provided that
                                                                  -------- ----
no Extension Period shall end on a date other than an Interest Payment Date for
the Debentures or extend beyond the Maturity Date of the Debentures. As a
consequence of such deferral, Distributions will also be deferred.
Notwithstanding such deferral, quarterly Distributions will continue to
accumulate with interest thereon (to the extent permitted by applicable law, but
not at a rate exceeding the rate of interest then accruing on the Debentures) at
the Coupon Rate compounded quarterly during any such Extension Period. Prior to
the termination of any Extension Period, the Debenture Issuer may further defer
payments of interest by further extending such Extension Period; provided that
                                                                 -------- ----
such Extension Period, together with all such previous and further extensions
within such Extension Period, may not (i) exceed 20 consecutive quarterly
periods, including the first quarterly period during such Extension Period, (ii)
end on a date other than an Interest Payment Date for the Debentures or (iii)
extend beyond the Maturity Date of the Debentures. Payments of accumulated
Distributions will be payable to Holders as they appear on the books and records
of the Trust on the record date immediately preceding the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

          Subject to receipt by the Sponsor of any and all required regulatory
approvals and to certain other conditions set forth in the Declaration and the
Indenture, the Property Trustee may, at the direction of the Sponsor, at any
time dissolve the Trust and, after satisfaction of liabilities to creditors of
the Trust as provided by applicable law, cause the Debentures to be distributed
to the Holders of the Securities in liquidation of the Trust or, simultaneously
with any redemption of the Debentures, cause a Like Amount of the Securities to
be redeemed by the Trust.

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