accountable in damages or otherwise to the Trust or any Covered Person for

and in a manner such Indemnified Person reasonably believed to be within the 
scope of the authority conferred on such Indemnified Person by this 
Declaration or by law, except that an Indemnified Person shall be liable for

                                       6



provisions of this Declaration, to the extent that they restrict the duties

                   herein or therein provides that an Indemnified Person shall 
                   act in a manner that is, or provides terms that are, fair 
                   and reasonable to the Trust or any holder of Securities,

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; and

        (c)  whenever in this Declaration an Indemnified Person is permitted 
or required to make a decision:

                   authority, the Indemnified Person shall be entitled to
                   consider such interests and factors as it desires,
                   including its own 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

             (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 

                                       7



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; and

             (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 and the Delaware 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 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 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.
