          (b)  an Indemnified Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports
or statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Trust, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits, losses, or any other facts
pertinent to the existence and amount of assets from which distributions to
holders of Securities might properly be paid.

SECTION 4.2    Fiduciary Duty.
               --------------

          (a)  To the extent that, at law or in equity, an Indemnified Person
has duties (including fiduciary duties) and liabilities relating thereto to
the 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 its good faith reliance on the provisions of this Declaration.  The
provisions of this Declaration, to the extent that they restrict the duties and
liabilities of an Indemnified Person otherwise existing at law or in equity, are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person;

          (b)  unless otherwise expressly provided herein:

               (i)  whenever a conflict of interest exists or arises between
          Covered Persons; or

                                       9


               (ii) whenever this Declaration or any other agreement
          contemplated 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,

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; and

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

               (i)  in its "discretion" or under a grant of similar 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 4.3    Indemnification.
               ---------------

          (a)  (i)  The Debenture Issuer shall indemnify, to the full extent
     permitted by law, any Company Indemnified Person who was or is a party or
     who is threatened to be made a party to any threatened, pending or
     completed action, suit or proceeding, whether civil, criminal,
     administrative or investigative (other than an action by or in the right of
     the Trust) by reason of the fact that he is or was a Company Indemnified
     Person against expenses (including attorneys' fees), judgments, fines and
     amounts paid in settlement actually and reasonably incurred by him in
     connection with such action, suit or proceeding if he acted in good faith
     and in a manner he reasonably believed to be in or not opposed to the
     best interests of the Trust, and, with respect to any criminal action or
     proceeding, had no reasonable

                                      10


     cause to believe his conduct was unlawful. The termination of any action,
     suit or proceeding by judgment, order, settlement, conviction, or upon a
     plea of nolo contendere or its equivalent, shall not, of itself, create a
     presumption that the Company Indemnified Person did not act in good faith
     and in a manner which he reasonably believed to be in or not opposed to the
     best interests of the Trust, and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that his conduct was unlawful.

          (ii)   The Debenture Issuer shall indemnify, to the full extent
     permitted by law, any Company Indemnified Person who was or is a party or
     who is threatened to be made a party to any threatened, pending or
     completed action or suit by or in the right of the Trust to procure a
     judgment in its favor by reason of the fact that he is or was a Company
     Indemnified Person against expenses (including attorneys' fees) actually
     and reasonably incurred by him in connection with the defense or
     settlement of such action or suit if he acted in good faith and in a manner
     he reasonably believed to be in or not opposed to the best interests of the
     Trust and except that no such indemnification shall be made in respect of
     any claim, issue or matter as to which such Company Indemnified Person
     shall have been adjudged to be liable to the Trust unless and only to the
     extent that the Court of Chancery of Delaware or the court in which such
     action or suit was brought shall determine upon application that, despite
     the adjudication of liability but in view of all the circumstances of the
     case, such person is fairly and reasonably entitled to indemnity for such
     expenses which such Court of Chancery or such other court shall deem
     proper.

          (iii)  To the extent that a Company Indemnified Person shall be
     successful on the merits or otherwise (including dismissal of an action
     without prejudice or the settlement of an action without admission of
     liability) in defense of any action, suit or proceeding referred to in
     paragraphs (i) and (ii) of this Section 4.3(a), or in defense of any claim,
     issue or matter therein, he shall be indemnified, to the full extent
     permitted by law, against expenses (including attorneys' fees) actually and
     reasonably incurred by him in connection therewith.

          (iv)   Any indemnification under paragraphs (i) and (ii) of this
     Section 4.3(a) (unless ordered by a court) shall be made by the Debenture
     Issuer only as authorized in the specific case upon a determination that
     indemnification of the Company Indemnified Person is proper in the
     circumstances because he has met the applicable standard of conduct set
     forth in paragraphs (i) and (ii). Such determination shall be made (1) by
     the Regular Trustees by a majority vote of a

                                      11


     quorum consisting of such Regular Trustees who were not parties to such
     action, suit or proceeding, (2) if such a quorum is not obtainable, or,
     even if obtainable, if a quorum of disinterested Regular Trustees so
     directs, by independent legal counsel in a written opinion, or (3) by the
     holder of the Common Securities of the Trust.

          (v)  Expenses (including attorneys' fees) incurred by a Company
     Indemnified Person in defending a civil, criminal, administrative or
     investigative action, suit or proceeding referred to in paragraphs (i) and
     (ii) of this Section 4.3(a) shall be paid by the Debenture Issuer in
     advance of the final disposition of such action, suit or proceeding upon
     receipt of an undertaking by or on behalf of such Company Indemnified
     Person to repay such amount if it shall ultimately be determined that he is
     not entitled to be indemnified by the Debenture Issuer as authorized in
     this Section 4.3(a).  Notwithstanding the foregoing, no advance shall be
     made by the Debenture Issuer if a determination is reasonably and promptly
     made (i) by the Regular Trustees by a majority vote of a quorum of
     disinterested Regular Trustees, (ii) if such a quorum is not obtainable,
     or, even if obtainable, if a quorum of disinterested Regular Trustees so
     directs, by independent legal counsel in a written opinion or (iii) the
     holder of the Common Securities of the Trust, that, based upon the facts
     known to the Regular Trustees, counsel or the holder of the Common
     Securities at the time such determination is made, such Company Indemnified
     Person acted in bad faith or in a manner that such person did not believe
     to be in or not opposed to the best interests of the Trust, or, with
     respect to any criminal proceeding, that such Company Indemnified Person
     believed or had reasonable cause to believe his conduct was unlawful. In no
     event shall any advance be made in instances where the Regular Trustees,
     independent legal counsel or the holder of the Common Securities reasonably
     determine that such person deliberately breached his duty to the Trust or
     its Common or Preferred Security holders.

          (vi) The indemnification and advancement of expenses provided by, or
     granted pursuant to, the other paragraphs of this Section 4.3(a) shall not
     be deemed exclusive of any other rights to which those seeking
     indemnification and advancement of expenses may be entitled under any
     agreement, vote of stockholders or disinterested directors of the Debenture
     Issuer or Preferred Security holders of the Trust or otherwise, both as to
     action in his official capacity and as to action in another capacity while
     holding such office. All rights to indemnification under this Section
     4.3(a) shall be deemed to be provided by a contract between the Debenture
     Issuer and each Company Indemnified Person who serves in such capacity at
     any time while this Section

                                      12


     4.3(a) is in effect. Any repeal or modification of this Section 4.3(a)
     shall not affect any rights or obligations then existing.

          (vii)   The Debenture Issuer or the Trust may purchase and maintain
     insurance on behalf of any person who is or was a Company Indemnified
     Person against any liability asserted against him and incurred by him in
     any such capacity, or arising out of his status as such, whether or not the
     Debenture Issuer would have the power to indemnify him against such
     liability under the provisions of this Section 4.3(a).

          (viii)  For purposes of this Section 4.3(a), references to "the
                                                                      ---
     Trust" shall include, in addition to the resulting or surviving entity, any
     -----
     constituent entity (including any constituent of a constituent) absorbed
     in a consolidation or merger, so that any person who is or was a director,
     trustee, officer or employee of such constituent entity, or is or was
     serving at the request of such constituent entity as a director, trustee,
     officer, employee or agent of another entity, shall stand in the same
     position under the provisions of this Section 4.3(a) with respect to the
     resulting or surviving entity as he would have with respect to such
     constituent entity if its separate existence had continued.

          (ix)    The indemnification and advancement of expenses provided by,
     or granted pursuant to, this Section 4.3(a) shall, unless otherwise
     provided when authorized or ratified, continue as to a person who has
     ceased to be a Company Indemnified Person and shall inure to the benefit of
     the heirs, executors and administrators of such a person.

     (b)  The Debenture Issuer agrees to indemnify (i) the Delaware Trustee,
(ii) any Affiliate of the Delaware Trustee, and (iii) any officers, directors,
shareholders, members, partners, employees, representatives, nominees,
custodians or agents of the Delaware Trustee (each of the Persons in clauses (i)
through (iii) being referred to as a "Fiduciary Indemnified Person") for, and to
                                      ----------------------------
hold each Fiduciary Indemnified Person harmless against, any loss, liability or
expense incurred without negligence or bad faith on its part, arising out of or
in connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses (including reasonable legal fees and
expenses) of defending itself against, or investigating, any claim or liability
in connection with the exercise or performance of any of its powers or duties
hereunder.  The obligation to indemnify as set forth in this Section 4.3(b)
shall survive the termination of this Declaration.

                                      13


SECTION 4.4    Outside Businesses.
               ------------------

          Any Covered Person, the Sponsor 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, the Sponsor 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 Sponsor 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.  Any Covered Person and the Delaware Trustee
may engage or be interested in any financial or other transaction with the
Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee
or agent for or may act on any committee or body of holders of, securities or
other obligations of the Sponsor or its Affiliates.
