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 the
authority conferred on such Indemnified Person by this Declaration or bylaw,
except that an Indemnified Person shall be liable for any such loss, damage or

                  (a) To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto

agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person;

                  (b) unless otherwise expressly provided herein:

                  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


                                       8
<PAGE>
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 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 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 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

<PAGE>
                  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
                  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 Common
                  Security Holder 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


                                       10
<PAGE>
                  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 Common
                  Security Holder of the Trust, that, based upon the facts known
                  to the Regular Trustees, counsel or the Common Security Holder
                  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 Common Security
                  Holder 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 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
(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 gross 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.

            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.

                        (iii) upon the entry of a decree of judicial dissolution

            consent of all of the Regular Trustees and the Sponsor.

                  (b) As soon as is practicable after the occurrence of an event
referred to in Section 5.2(a), the Trustees shall file a certificate of
cancellation with the Secretary of State of the State of Delaware.

            Section 5.3 Governing Law.

            Whenever in this Declaration any of the parties hereto is named or
referred to, the successors and assigns of such party shall be deemed to be

and the Trustees shall bind and inure to the benefit of their respective
successors and assigns, whether so expressed.

            Section 5.6 Partial Enforceability.

            If any provision of this Declaration, or the application of such
provision to any Person or circumstance, shall be held invalid, the remainder of
this Declaration, or the application of such provision to persons or
circumstances other than those to which it is held invalid, shall not be
affected thereby.

            Section 5.7 Counterparts.

            This Declaration may contain more than one counterpart of the
