                         [FORM OF 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 $10 per
Series A Capital Security, such rate being the rate of interest payable on the
Series A 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 Series A Debentures held by the Property Trustee and to the
extent the Property Trustee has funds legally available therefor.

                  Distributions on the Series A 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 December [___],
1998 and will be payable quarterly in arrears, on March 31, June 30, September
30 and December 31 of each year, commencing March 31, 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 Series A 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 Series A Debentures or extend beyond the Maturity
Date of the Series A 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 Series A 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 Series A Debentures or (iii)
extend beyond the Maturity Date of the Series A 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
Series A Debentures to be distributed to the Holders of the Securities in
liquidation of the Trust or, simultaneously with any redemption of the Series A
Debentures, cause a Like Amount of the Securities to be redeemed by the Trust.

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