existing dividend policy of the Company, or (y) amend any provision of the LLC
Agreement that affects the rights of the Manager thereunder or hereunder.

otherwise agreed by the Manager in writing.

                                    INDEMNITY

            Section 11.1 Indemnification of Manager. The Company and each
Managed Subsidiary, jointly and severally, agrees to indemnify the Manager, any
controlling person of the Manager, and each of their respective directors,
officers, employees, agents, Affiliates and representatives (each, an
"INDEMNIFIED PARTY") and hold each of them harmless against any and all losses,
(including lost profits) claims, damages, expenses or liabilities, joint or
several (collectively, "LIABILITIES"), to which the Indemnified Parties may
become liable, directly or indirectly, arising out of, or relating to, this
Agreement, unless it is finally judicially determined that the Liabilities
resulted from the gross negligence, willful misconduct, bad faith or reckless
disregard of duty of any Indemnified Party or fraudulent or dishonest acts of
such Indemnified Party. The Company and the Managed Subsidiaries further agree
to reimburse each Indemnified Party immediately upon request for all expenses
(including reasonable attorneys' fees and expenses) as they are incurred in
connection with the investigation of, preparation for, defense of, or providing
evidence in any action, claim, suit, proceeding or investigation, directly or
indirectly, arising out of, or relating to, this Agreement or the Manager's
services hereunder, whether or not pending or threatened and whether or not any
Indemnified Party is a party to such proceeding. The Company and the Managed
Subsidiaries also agree that no Indemnified Party shall have any liability
(whether direct or indirect, in contract or tort or otherwise) to the Company,
the Managed Subsidiaries, or any person asserting claims on behalf of or in
right of the Company or the Managed Subsidiaries, directly or indirectly,
arising out of, or relating to, this Agreement or the Manager's services
thereunder, unless it is finally judicially determined that such Liability
resulted from the gross negligence, willful misconduct, bad faith or reckless
disregard of duty of such Indemnified Party or fraudulent or dishonest acts of
such Indemnified

                                       31


Party. Moreover, in no event, regardless of the legal theory advanced, shall any
Indemnified Party be liable to the Company, the Managed Subsidiaries, or any
person asserting claims on behalf of or in the right of the Company or the
Managed Subsidiaries for any consequential, indirect, incidental or special
damages of any nature. In the event that an Indemnified Party is requested or
required to appear as a witness in any action brought by or on behalf of or
against the Company or the Managed Subsidiaries or any Affiliate of the Company
or the Managed Subsidiaries in which such Indemnified Party is not named as a
defendant, the Company and the Managed Subsidiaries agree to reimburse the
Manager for all expenses incurred by it in connection with such Indemnified
Party's appearing and preparing to appear as such a witness, including, without
limitation, the reasonable fees and disbursements of its legal counsel.

            The Company and the Managed Subsidiaries agree that, without the
Manager's prior written consent, they will not settle, compromise or consent to
the entry of any judgment in or otherwise seek to terminate any claim, action,
suit, proceeding or investigation in respect of which indemnification could be
sought hereunder (whether or not the Manager or any other Indemnified Party is
an actual or potential party to such claim, action, suit, proceeding or
investigation), unless (a) such settlement, compromise, consent or termination
includes an unconditional release of each Indemnified Party from any liabilities
arising out of such claim action, suit, proceeding or investigation and (b) the
parties agree that the terms of such settlement shall remain confidential.

            Section 11.2 Indemnification of Company. The Manager agrees to
indemnify the Company and the Trust and hold each of them harmless against any
Liabilities to the same extent as the foregoing indemnity from the Company and
the Managed Subsidiaries to the Manager, but only insofar as it is finally
judicially determined that the Liabilities arose out of or were based on the
gross negligence, willful misconduct, bad faith or reckless disregard of duty of
the Manager in the performance of its duties under this Agreement or its
fraudulent or dishonest acts.

            Section 11.3 Indemnification. The rights of the Indemnified Parties
referred to above shall be in addition to any rights that any Indemnified Party
may otherwise have. The indemnities referred to in this Article XI survive the
termination of this Agreement.

                                  ARTICLE XII

                     LIMITATION OF LIABILITY OF THE MANAGER

            Section 12.1 Limitation of Liability. The Manager shall not be
liable for, and the Company and the Managed Subsidiaries will not take any
action against the Manager to hold the Manager liable for, any error of judgment
or mistake of law or for any loss suffered by the Company and the Managed
Subsidiaries (including, without limitation, by reason of the purchase, sale or
retention of any security) in connection with the performance of the Manager's
duties under this Agreement, except for a loss resulting from gross negligence,
willful misconduct or bad faith on the part of the Manager in the performance of
its duties under this Agreement, or by reason of its reckless disregard of its
obligations and duties under this Agreement or its fraudulent or dishonest acts.

                                       32


            Section 12.2 Manager May Rely. The Manager may take and may act
upon:

            (a) the opinion or advice of legal counsel, which may be in-house
      counsel to the Company or the Manager, any U.S.-based law firm of
      recognized standing, or other legal counsel reasonably acceptable to the
      Board of Directors of the Company, in relation to the interpretation of
      this Agreement or any other document (whether statutory or otherwise) or
      generally in connection with the Company;

            (b) advice, opinions, statements or information from bankers,
      accountants, auditors, valuation consultants and other persons consulted
      by the Manager who are in each case believed by the Manager in good faith
      to be expert in relation to the matters upon which they are consulted;

            (c) a document which the Manager believes in good faith to be the
      original or a copy of an appointment by a Member in respect of an LLC
      Interest or holder of a Trust Certificate in respect of a share of Trust
      Stock of a person to act as their agent for any purpose connected with the
      Company; and

            (d) any other document provided to the Manager in connection with
      the Company upon which it is reasonable for the Manager to rely;

and the Manager will not be liable for anything done, suffered or omitted by it
in good faith in reliance upon such opinion, advice, statement, information or
document.
