              (ii) the Investment Guarantee Trustee shall not be liable for any
    error of judgment made in good faith by a Responsible Officer of the

    Guarantee 

                                        8


    Trustee was negligent in ascertaining the pertinent facts upon which such

    Investment Guarantee Trustee to expend or risk its own funds or otherwise
    incur personal financial liability in the performance of any of its duties
    or in the exercise of any of its rights or powers, if the Investment
    Guarantee Trustee shall have reasonable grounds for believing that the
    repayment of such funds or liability is not reasonably assured to it under

    satisfactory to the Investment Guarantee Trustee, against such risk or
    liability is not reasonably assured to it.

    resolution, certificate, statement, instrument, opinion, report, notice,
    request, direction, consent, order, bond, debenture, note, other evidence
    of indebtedness or other paper or document believed by it to be genuine and
    to have been signed, sent or presented by the proper party or parties.

              (ii) Any direction or act of the Guarantor contemplated by this
    Investment Guarantee shall be sufficiently evidenced by an Officers'
    Certificate.

              (iii) Whenever, in the administration of this Investment
    Guarantee, the Investment Guarantee Trustee shall deem it desirable that a
    matter be proved or established before taking, suffering or omitting any
    action hereunder, the Investment Guarantee Trustee (unless other evidence
    is herein specifically prescribed)  may, in the absence of bad faith on its
    part, request and conclusively rely upon an Officers' Certificate which,
    upon receipt of such request, shall be promptly delivered by the Guarantor.

                                       9


              (iv) The Investment Guarantee Trustee shall have no duty to see
    to any recording, filing or registration of any instrument (or any
    rerecording, refiling or registration thereof).

              (v)  The Investment Guarantee Trustee may consult with counsel of
    its selection, and the advice or opinion of such counsel with respect to
    legal matters shall be full and complete authorization and protection in
    respect of any action taken, suffered or omitted by it hereunder in good
    faith and in accordance with such advice or opinion.  Such counsel may be
    counsel to the Guarantor or any of its Affiliates and may include any of
    its employees.  The Investment Guarantee Trustee shall have the right at
    any time to seek instructions concerning the administration of this
    Investment Guarantee from any court of competent jurisdiction.

              (vi) The Investment Guarantee Trustee shall be under no
    obligation to exercise any of the rights or powers vested in it by this
    Investment Guarantee at the request or direction of any Holder, unless such
    Holder shall have provided to the Investment Guarantee Trustee such
    security and indemnity, reasonably satisfactory to the Investment Guarantee
    Trustee, against the costs, expenses (including attorneys' fees and
    expenses and the expenses of the Investment Guarantee Trustee's agents,
    nominees or custodians) and liabilities that might be incurred by it in
    complying with such request or direction, including such reasonable
    advances as may be requested by the Investment Guarantee Trustee; provided
    that, nothing contained in this Section 3.2(a)(vi) shall be taken to
    relieve the Investment Guarantee Trustee, upon the occurrence of an Event
    of Default, of its obligation to exercise the rights and powers vested in
    it by this Investment Guarantee.

              (vii)     The Investment Guarantee Trustee shall not be bound to
    make any investigation into the facts or matters stated in any resolution,
    certificate, statement, instrument, opinion, report, notice, request,
    direction, consent, order, bond, debenture, note, other evidence of
    indebtedness or other paper or document, but the Investment Guarantee
    Trustee, in its discretion, may make such further inquiry or investigation
    into such facts or matters as it may see fit.

              (viii)    The Investment Guarantee Trustee may execute any of the
    trusts or powers hereunder or perform any duties hereunder either directly
    or by or through agents, nominees, custodians or attorneys, and the
    Investment Guarantee Trustee shall not be responsible for any 

                                      10


    misconduct or negligence on the part of any agent or attorney appointed 
    with due care by it hereunder.

              (ix) Any action taken by the Investment Guarantee Trustee or its
    agents hereunder shall bind the holders of the Affiliate Debenture, and the
    signature of the Investment Guarantee Trustee or its agents alone shall be
    sufficient and effective to perform any such action.  No third party shall
    be required to inquire as to the authority of the Investment Guarantee
    Trustee to so act or as to its compliance with any of the terms and
    provisions of this Investment Guarantee, both of which shall be
    conclusively evidenced by the Investment Guarantee Trustee or its agent
    taking such action.

              (x)  whenever in the administration of this Investment Guarantee
    the Investment Guarantee Trustee shall deem it desirable to receive
    instructions with respect to enforcing any remedy or right or taking any
    other action hereunder, the Investment Guarantee Trustee (i) may request
    instructions from the Holders of a Majority in aggregate principal amount
    of the Affiliate Debenture, (ii) may refrain from enforcing such remedy or
    right or taking such other action until such instructions are received, and
    (iii) shall be fully protected in conclusively relying on or acting in
    accordance with such instructions.

              (xi) The Investment Guarantee Trustee shall not be liable for any
    action taken, suffered, or omitted to be taken by it in good faith, without
    negligence, and reasonably believed by it to be authorized or within the
    discretion or rights or powers conferred upon it by this Investment
    Guarantee.

         (b)  No provision of this Investment Guarantee shall be deemed to
impose any duty or obligation on the Investment Guarantee Trustee to perform any
act or acts or exercise any right, power, duty or obligation conferred or
imposed on it in any jurisdiction in which it shall be illegal, or in which the
Investment Guarantee Trustee shall be unqualified or incompetent in accordance
with applicable law, to perform any such act or acts or to exercise any such
right, power, duty or obligation.  No permissive power or authority available to
the Investment Guarantee Trustee shall be construed to be a duty.

         SECTION 3.3 Not Responsible for Recitals or Issuance of Investment
Guarantee

         The recitals contained in this Investment Guarantee shall be taken as
the statements of the Guarantor, and the Investment Guarantee Trustee does not
assume any responsibility for their correctness.  The Investment Guarantee
Trustee makes no 

                                     11


representation as to the validity or sufficiency of this Investment Guarantee.

                             INVESTMENT GUARANTEE TRUSTEE

         SECTION 4.1 Investment Guarantee Trustee; Eligibility

         (a)  There shall at all times be an Investment Guarantee Trustee which
shall:

              (i)  not be an Affiliate of the Guarantor; and

              (ii) be a corporation organized and doing business under the laws
    of the United States of America or any State or Territory thereof or of the
    District of Columbia, or a corporation or Person permitted by the
    Securities and Exchange Commission to act as an institutional trustee under
    the Trust Indenture Act, authorized under such laws to exercise corporate
    trust powers, having a combined capital and surplus of at least 50 million
    U.S. dollars ($50,000,000), and subject to supervision or examination by
    Federal, State, Territorial or District of Columbia authority.  If such
    corporation publishes reports of condition at least annually, pursuant to
    law or to the requirements of the supervising or examining authority
    referred to above, then, for the purposes of this Section 4.1(a)(ii), the
    combined capital and surplus of such corporation shall be deemed to be its
    combined capital and surplus as set forth in its most recent report of
    condition so published.

         (b)  If at any time the Investment Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Investment Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section 4.2(c).

         (c)  If the Investment Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Investment Guarantee Trustee and Guarantor shall in all
respects comply with the provisions of Section 310(b) of the Trust Indenture
Act.

         SECTION 4.2 Appointment, Removal and Resignation of Investment
Guarantee Trustee

         (a)  Subject to Section 4.2(b), the Investment Guarantee Trustee may
be appointed or removed without cause at any time by the Guarantor except during
a default or an Event of Default.

                                       12



         (b)  The Investment Guarantee Trustee shall not be removed in
accordance with Section 4.2(a) until a Successor Investment Guarantee Trustee
has been appointed and has accepted such appointment by written instrument
executed by such Successor Investment Guarantee Trustee and delivered to the
Guarantor.

         (c)  The Investment Guarantee Trustee shall hold office until a
Successor Investment Guarantee Trustee shall have been appointed or until its
removal or resignation.  The Investment Guarantee Trustee may resign from office
(without need for prior or subsequent accounting) by an instrument in writing
executed by the Investment Guarantee Trustee and delivered to the Guarantor,
which resignation shall not take effect until a Successor Investment Guarantee
Trustee has been appointed and has accepted such appointment by instrument in
writing executed by such Successor Investment Guarantee Trustee and delivered to
the Guarantor and the resigning Investment Guarantee Trustee.

         (d)  If no Successor Investment Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 30
days after delivery of an instrument of removal or resignation, the Investment
Guarantee Trustee resigning or being removed may petition any court of competent
jurisdiction for appointment of a Successor Investment Guarantee Trustee.  Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Investment Guarantee Trustee.

         (e)  No Investment Guarantee Trustee shall be liable for the acts or
omissions to act of any Successor Investment Guarantee Trustee.

         (f)  Upon termination of this Investment Guarantee or removal or
resignation of the Investment Guarantee Trustee pursuant to this Section 4.2,
the Guarantor shall pay to the Investment Guarantee Trustee all amounts due to
the Investment Guarantee Trustee accrued to the date of such termination,
removal or resignation.

                                      ARTICLE V
                                      GUARANTEE

         SECTION 5.1 Guarantee

         The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), as and when due, regardless of any defense, right of
set-off or counterclaim that the Issuer may have or assert.  The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Guarantor to the Holders or by causing the Issuer to pay
such amounts to the Holders.

                                        13




         SECTION 5.2 Waiver of Notice and Demand

         The Guarantor hereby waives notice of acceptance of this Investment
Guarantee and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Issuer
or any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands.

         SECTION 5.3 Obligations Not Affected

         The obligations, covenants, agreements and duties of the Guarantor
under this Investment Guarantee shall in no way be affected or impaired by
reason of the happening from time to time of any of the following:

         (a)  the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Affiliate Debenture to be performed
or observed by the Issuer;

         (b)  the extension of time for the payment by the Issuer of all or any
portion of the interest, principal or premium, if any, or any other sums payable
under the terms of the Affiliate Debenture or the extension of time for the
performance of any other obligation under, arising out of, or in connection
with, the Affiliate Debenture (other than an extension of time for payment of
interest during an Extension Period, as defined in the Affiliate Debenture,
permitted by the Affiliate Indenture);

         (c)  any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Affiliate Debenture, or
any action on the part of the Issuer granting indulgence or extension of any
kind;

         (d)  the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or readjustment of debt
of, or other similar proceedings affecting, the Issuer or any of the assets of
the Issuer;

         (e)  any invalidity of, or defect or deficiency in, the Affiliate
Debenture;

         (f)  the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or


                                      14



         (g)  any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

         SECTION 5.4 Rights of Holders

         (a)  The Holders of a Majority in aggregate principal amount of the
Affiliate Debenture have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Investment Guarantee
Trustee in respect of this Investment Guarantee or exercising any trust or power
conferred upon the Investment Guarantee Trustee under this Investment Guarantee.

         (b)  If the Investment Guarantee Trustee fails to enforce its rights
under the Investment Guarantee after a Holder of the Affiliate Debenture has
made a written request, such Holder of the Affiliate Debenture may institute a
legal proceeding directly against the Guarantor to enforce the Investment
Guarantee Trustee's rights under this Investment Guarantee, without first
instituting a legal proceeding against the Issuer, the Investment Guarantee
Trustee or any other Person.  Notwithstanding the foregoing, if the Guarantor
has failed to make a Guarantee Payment, a Holder of the Affiliate Debenture may
directly institute a proceeding in such Holder's own name against the Guarantor
for enforcement of the Investment Guarantee for such payment.  The Guarantor
waives any right or remedy to require that any action be brought first against
the Issuer or any other person or entity before proceeding directly against the
Guarantor.

         SECTION 5.5 Guarantee of Payment

         This Investment Guarantee creates a guarantee of payment and not of
collection.

         SECTION 5.6 Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the
Holders of Affiliate Debenture against the Issuer in respect of any amounts paid
to such Holders by the Guarantor under this Investment Guarantee; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of 

                                      15


payment under this Investment Guarantee, if, at the time of any such payment,
any amounts are due and unpaid under this Investment Guarantee.  If any amount
shall be paid to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

         SECTION 5.7 Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Affiliate
Debenture, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Investment
Guarantee notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.

                                      ARTICLE VI
                                    SUBORDINATION

         SECTION 6.1 Ranking

         This Investment Guarantee will constitute an unsecured obligation of
the Guarantor and will rank (i) subordinate and junior in right of payment to
all other liabilities of the Guarantor, (ii) pari passu with the most senior
preferred or preference stock now or hereafter issued by the Guarantor and with
any other guarantee now or hereafter entered into by the Guarantor in respect of
any preferred or preference stock of any Affiliate of the Guarantor, and (iii)
senior to the Guarantor's common stock.  The holders of obligations of the
Guarantor that are senior to the obligations under the Investment Guarantee
(including, but not limited to, obligations constituting Senior Indebtedness)
shall be entitled to the same rights in payment default or dissolution,
liquidation and reorganization in respect of this Investment Guarantee that
inure to the holders of Senior Indebtedness as against the holders of the
Company Debenture specified in Sections 1102, 1103 and 1105 of the Company
Indenture.

                                     ARTICLE VII
                                     TERMINATION

         SECTION 7.1 Termination

         This Investment Guarantee shall terminate upon the repayment in full
(whether at maturity, upon redemption or otherwise) of all of the principal of,
premium, if any, and interest on (including all accrued and unpaid interest
thereon) and any other amounts payable in respect of the Affiliate Debenture. 
Notwithstanding the foregoing, this Investment Guarantee will continue to be
effective or will be reinstated, as 

                                      16


the case may be, if at any time any Holder of the Affiliate Debenture must
restore payment of any sums paid under the Affiliate Debenture or under this
Investment Guarantee.

                                     ARTICLE VIII
                                   INDEMNIFICATION

         SECTION 8.1 Exculpation

         (a)  No Indemnified Person shall be liable, responsible or accountable
in damages or otherwise to the Guarantor 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 in accordance with this Investment
Guarantee and in a manner that such Indemnified Person reasonably believed to be
within the scope of the authority conferred on such Indemnified Person by this
Investment Guarantee or by law, 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.

         (b)  An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Guarantor and upon such information, opinions,
reports or statements presented to the Guarantor 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 Guarantor, 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 principal, premium, interest or other payments to Holders of the Affiliate
Debenture might properly be paid.

         SECTION 8.2 Indemnification

         The Guarantor agrees to indemnify each Indemnified Person for, and to
hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim 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 8.2 shall survive the termination of this
Investment Guarantee.

                                   ARTICLE IX
                                  MISCELLANEOUS

         SECTION 9.1 Successors and Assigns

         All guarantees and agreements contained in this Investment Guarantee
shall bind the successors, assigns, receivers, trustees and representatives of
the Guarantor and shall inure to the benefit of the Holders of the Partnership
Preferred Securities then outstanding.  The Company may not assign its rights or
delegate its obligations hereunder without the prior approval of the Holders of
at least a majority of the aggregated stated liquidation preference of the
Partnership Preferred Securities then outstanding, except that the Company may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other corporation, provided that in any
such case either the Company shall be the continuing corporation, or the
successor corporation shall expressly assume the obligations of the Guarantor
hereunder.

         SECTION 9.2 Amendments

rights of Holders of Partnership Preferred Securities (in which case no consent
will be required), this Investment Guarantee may be amended only with the prior
approval of the Holders of not less than a majority in liquidation preference of
the outstanding Partnership Preferred Securities, provided that so long as the
Property Trustee of the Trust is the Holder of the Partnership Preferred
Securities, such amendment will not be effective without the prior written
approval of a majority in liquidation amount of the outstanding Trust Preferred
Securities.

         SECTION 9.3 Consolidations and Mergers

         The Guarantor may consolidate with, or sell, lease or convey all or

payment of the Guarantee Payments payable pursuant to Section 5.1 hereof and the
due and punctual performance and observance of all of the covenants and
conditions of this Investment Guarantee to be performed by the Guarantor by a
separate guarantee satisfactory to the Investment Guarantee Trustee (as defined

delivered to the Investment Guarantee Trustee by such corporation, and (ii) the
Guarantor or 

                                       18


such successor corporation, as the case may be, shall not, immediately after

in the performance of any such covenant or condition.
