                           LIMITATION OF LIABILITY OF
                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 4.1.    EXCULPATION.

           (a)  No Indemnified Person shall be liable, responsible or 
accountable in damages or otherwise to the Trust or any Covered Person for any 
loss, damage or claim incurred 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 
the authority conferred on such Indemnified Person by this Declaration or by 
law, 

                                        7



except that an Indemnified Person shall be liable for any such loss, damage or 
claim incurred by reason of such Indemnified Person's gross negligence or 
willful misconduct with respect to such acts or omissions; and

           (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.

           (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

                (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 

                                        8



           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 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 

                                        9



         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 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 

                                       10



         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 the (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

                                       11



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.

amendment shall also be approved by the Delaware Trustee.

           Sponsor's charter or of the Trust's certificate of trust;

                (iii)  upon the entry of a decree of judicial dissolution of the
           Sponsor, or the Trust; and

                (iv)   before the issue of any Securities, with the consent of 
           all of the Regular Trustees and the Sponsor; and

           (b)  as soon as is practicable after the occurrence of an event
