Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for

                  reasonable to the Trust or any holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

     (c)    Whenever in this Declaration an Indemnified Person is permitted or

                  interests, and shall have no duty or obligation to give any
                  consideration to any interest of or factors affecting the
                  Trust or any other Person; or

                                       6
<PAGE>

            (ii)  in its "good faith" or under another express standard,

the Indemnified Person shall act under such express standard and shall not be
subject to any other or different standard imposed by this Declaration or by
applicable law.

SECTION 4.4.   INDEMNIFICATION.

     (a)     To the fullest extent permitted by applicable law, the Sponsor
shall indemnify and hold harmless each Indemnified Person from and against any
loss, damage or claim incurred by such Indemnified Person by reason of any act
or omission performed or omitted by such Indemnified Person in good faith on
behalf of the Trust and in a manner such Indemnified Person reasonably believed
to be within the scope of authority conferred on such Indemnified Person by this
Declaration, except that no Indemnified Person shall be entitled to be
indemnified in respect of any loss, damage or claim incurred by such Indemnified
Person by reason of gross negligence or willful misconduct with respect to such
acts or omissions.

     (b)     To the fullest extent permitted by applicable law, expenses
(including legal fees) incurred by an Indemnified Person in defending any claim,
demand, action, suit or proceeding shall, from time to time, be advanced by the
Sponsor prior to the final disposition of such claim, demand, action, suit or
proceeding upon receipt by the Sponsor of an undertaking by or on behalf of the
Indemnified Person to repay such amount if it shall be determined that the
Indemnified Person is not entitled to be indemnified as authorized in Section
4.4(a).

SECTION 4.5.   OUTSIDE BUSINESSES.

     Any Covered Person, the Delaware Trustee and the Property Trustee may
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the business
of the Trust, and the Trust and the holders of Securities shall have no rights
by virtue of this Declaration in and to such independent ventures or the income
or profits derived therefrom and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper.  No Covered Person, the Property Trustee or the Delaware Trustee shall
be obligated to present any particular investment or other opportunity to the
Trust even if such opportunity is of a character that, if presented to the
Trust, could be taken by the Trust, and any Covered Person, the Property Trustee
and the Delaware Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity.
