reasonable person in the position of the Guarantee  Trustee,  against the costs,
expenses (including  attorneys' fees and expenses) 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 Guarantee Trustee; provided that,
nothing contained in this Section -------
       3.2(a)(vi)  shall be taken to relieve  the  Guarantee  Trustee,  upon the
occurrence of an Event of Default, of its obligation to exer cise the rights and
powers vested in it by this Guarantee Agree ment.

                   (vii) The  Guarantee  Trustee  shall not be bound to make any

with due care by it hereunder.

                  (ix) Any action taken by the  Guarantee  Trustee or its agents
hereunder shall bind the Holders of the Partnership Pre ferred  Securities,  and
the signature of the  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 Guarantee  Trustee to so act or as to its com
pliance with any of the terms and provisions of this Guarantee  Agreement,  both
of which shall be  conclusively  evidenced  by the  Guarantee  Trustee's  or its
agent's taking such action.

                   (x)  Whenever  in  the   administration   of  this  Guarantee
Agreement the Guarantee Trustee shall deem it desirable to receive  instructions

hereunder,  the Guarantee Trustee (i) may request  instructions from the Holders
of a Majority  in  aggregate  liquidation  amount of the  Partnership  Preferred
Securities,  (ii) may refrain from enforcing such remedy or right or taking such
other action until such  instructions  are received and (iii) shall be protected
in acting in accordance with such instructions.

             (b) No provision  of this  Guarantee  Agreement  shall be deemed to
impose any duty or  obligation  on the  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  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 Guarantee Trustee
shall be construed to be a duty.

the intent of this Section 5.3 that the  obligations of the Guarantor  hereunder
shall be absolute and unconditional under any and all circumstances.

             SECTION 5.5 Guarantee of Payment.  This Guarantee Agreement
                         --------------------
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  Partnership  Preferred  Securities

Guarantor under this Guarantee Agreement; 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 payment under this Guarantee Agreement,  if, at the time of any such
payment, any amounts are due and unpaid under this Guarantee  Agreement.  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

             SECTION 6.1 Limitation of Transactions.  So long as any
                         --------------------------
Partnership  Preferred  Securities remain  outstanding,  if (i) there shall have
occurred an Event of Default  hereunder or an event of default under the Limited
Partnership  Agreement  or (ii) if the  Guarantor  exercises  its right to defer

                              SUBORDINATION

             SECTION 7.1 Subordination.  This Guarantee Agreement will
                         -------------

provisions.  Holders  of  Senior  Indebtedness  need not prove  reliance  on the
subordination provisions hereof.

             SECTION 7.2 Payment Over of Proceeds Upon Dissolution, etc.
                         -----------------------------------------------
Upon any payment or  distribution  of assets of the Guarantor to creditors  upon
any liquidation,  dissolution,  winding-up,  reorganization,  assignment for the
benefit of creditors,  marshalling of assets or  liabilities or any  bankruptcy,
insolvency or similar  proceedings  of the Guarantor  (each such event,  if any,
herein sometimes referred to as a "Proceeding"):

             (i) the holders of Senior Indebtedness shall be entitled to receive
payment in full in cash of all  amounts due on or to become due on or in respect
of all Senior  Indebtedness,  before the  Holders  are  entitled  to receive any
payment  (including  any  payment  to  Holders  made  in  respect  of any  other
Indebtedness of the Guarantor subordinated to the payment of the Guarantee, such
payment or distribution being hereinafter  referred to as a "Junior Subordinated
Payment"), on account of the Guarantee or on account of any purchase, redemption
or other  acquisition of the Guarantee by the  Guarantor,  any Subsidiary of the
Guarantor,  the  Guarantee  Trustee  or any  Paying  Agent  (all such  payments,
distributions,  purchases,  redemptions  and  acquisitions,  whether  or  not in
connection with a Proceeding, herein referred to, individually and collectively,
as a "Guarantee Subordinated Payment"); and

             (ii) any payment or  distribution of assets of the Guarantor of any
kind or  character,  whether  in cash,  property  or  securities,  by set-off or
otherwise,  to which the Holders or the Guarantee  Trustee would be entitled but
for the provisions of this Article (including,  without  limitation,  any Junior
Subordinated Payment) shall be paid by the liquidating trustee or agent or other
Person making such payment or distribution,  whether a trustee in bankruptcy,  a
receiver or liquidating trustee or otherwise,  directly to the holders of Senior
Indebtedness or their  representative  or  representatives  or to the trustee or
trustees under any indenture under which any instruments  evidencing any of such
Senior  Indebtedness  may have been issued,  ratably  according to the aggregate
amounts  remaining  unpaid  on  account  of  the  Senior  Indebtedness  held  or
represented by each, to the extent  necessary to make payment in full in cash of
all Senior Indebtedness  remaining unpaid, after giving effect to any concurrent
payment to the holders of such Senior Indebtedness.

             In the event that, notwithstanding the foregoing provisions of this
Section,  the  Guarantee  Trustee or a Holder shall have  received in connection
with any  Proceeding  any  Guarantee  Subordinated  Payment  before  all  Senior
Indebtedness is paid in full or payment  thereof  provided for in cash, then and
in such  event  such  Guarantee  Subordinated  Payment  shall  be  paid  over or
delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian,  assignee,  agent or other Person making payment or  distribution  of
assets  of  the  Guarantor  for   application  to  the  payment  of  all  Senior
Indebtedness  remaining  unpaid,  to the  extent  necessary  to pay  all  Senior
Indebtedness in full in cash after giving effect to any concurrent payment to or
for the holders of Senior Indebtedness.

             For  purposes  of this  Article  only,  the words  "any  payment or
distribution of any kind or character,  whether in cash, property or securities"
shall not be deemed to include a payment or  distribution of stock or securities
of the  Guarantor  provided  for by a plan  of  reorganization  or  readjustment
authorized  by an order or  decree  of a court of  competent  jurisdiction  in a
reorganization  proceeding  under any applicable  bankruptcy law or of any other
corporation  provided for by such plan of reorganization  or readjustment  which
stock or securities are subordinated in right of payment to all then outstanding
Senior  Indebtedness to  substantially  the same extent,  or to a greater extent
than,  the  Guarantee  is so  subordinated  as  provided  in this  Article.  The
consolidation  of the  Guarantor  with,  or the  merger of the  Guarantor  into,
another Person or the liquidation or dissolution of the Guarantor  following the
conveyance or transfer of all or substantially  all of its properties and assets
as an entirety  to another  Person  upon the terms and  conditions  set forth in
Article Eight of the Indenture shall not be deemed a Proceeding for the purposes
of this  Section if the Person  formed by such  consolidation  or into which the
Guarantor is merged or the Person which  acquires by conveyance or transfer such
properties  and assets as an entirety,  as the case may be, shall,  as a part of
such consolidation,  merger,  conveyance or transfer, comply with the conditions
set forth in Article Eight of the Indenture.

             SECTION 7.3 No Payment When Senior Indebtedness In Senior
                         ----------------------------------------------
Payment Default or Senior Indebtedness Accelerated.  In the event that (a)
- --------------------------------------------------
any Senior  Payment  Default (as defined  below)  shall have  occurred  and such
Senior Indebtedness shall have become, by reason thereof,  due and payable prior
to the stated maturity thereof, then no Guarantee  Subordinated Payment shall be
made (except that, so long as Citizens Capital shall be the holder of all of the
Outstanding  Convertible  Debentures,  payment  may be made in shares of capital
stock),  unless and until such Senior  Payment  Default shall have been cured or
waived in  writing  or shall have  ceased to exist or all  amounts  then due and
payable in respect of such  Senior  Indebtedness  (including  amounts  that have
become  and remain  due by  acceleration)  shall have been paid in full in cash.
"Senior Payment  Default" means any default (which default has continued  beyond
any applicable grace and/or cure period (if any), in the payment of principal of
(or premium, if any) or interest on any Senior Indebtedness when due, whether at
the stated maturity of any such payment or by declaration of acceleration,  call
for redemption, mandatory payment or prepayment or otherwise.

             In the event that any Senior Nonmonetary Default (as defined below)
shall have occurred and be continuing,  then,  upon the receipt by the Guarantor
and the Guarantee Trustee of written notice of such Senior  Nonmonetary  Default
from the  Designated  Senior  Holder of such  certain  Senior  Indebtedness,  no
Guarantee  Subordinated  Payment (except that, so long as Citizens Capital shall
be the holder of all of the Outstanding Convertible  Debentures,  payment may be
made in shares of capital stock) shall be made,  during the period (the "Payment
Blockage Period")  commencing on the date of such receipt of such written notice
and ending  (subject to any blockage of payments  that may then or thereafter be
in effect as the result of any Senior Payment Default) on the earlier of (i) the
date on which the Senior  Indebtedness to which such Senior Nonmonetary  Default
relates is discharged or such Senior  Nonmonetary  Default shall have been cured
or waived in  writing  or shall  have  ceased to exist and any  acceleration  of
Senior  Indebtedness to which such Senior Nonmonetary Default relates shall have
been  rescinded or annulled or (ii) the 179th day after the date of such receipt
of such  written  notice.  No more  than  one  Payment  Blockage  Period  may be
commenced  with respect to the  Guarantee  during any period of 360  consecutive
days and there shall be a period of at least 181 consecutive days in each period
of 360 consecutive days when no Payment Blockage Period is in effect.  Following
the  commencement  of any  Payment  Blockage  Period,  the holders of the Senior
Indebtedness  will be precluded from  commencing a subsequent  Payment  Blockage
Period until the conditions  set forth in the preceding  sentence are satisfied.
For all purposes of this paragraph,  no Senior Nonmonetary  Default that existed
or was continuing on the date of  commencement  of any Payment  Blockage  Period
with respect to the Senior Indebtedness  initiating such Payment Blockage Period
shall be, or be made,  the basis for the  commencement  of a subsequent  Payment
Blockage  Period by  holders  of Senior  Indebtedness  or their  representatives
unless such Senior Nonmonetary Default shall have been cured for a period of not
less than 90 consecutive days.  "Senior  Nonmonetary  Default" means any default
(other than a Senior Payment Default) or any event which,  after notice or lapse
of time (or  both),  would  become an event of  default,  under the terms of any
instrument  or  agreement   pursuant  to  which  any  Senior   Indebtedness   is
outstanding,  permitting  (after  notice  or lapse of time or both)  one or more
holders  of such  Senior  Indebtedness  (or a trustee  or agent on behalf of the
holders  thereof) to declare such Senior  Indebtedness  due and payable prior to
the date on which it would otherwise become due and payable.

             In the event that,  notwithstanding  the  foregoing,  the Guarantor
shall make any Guarantee  Subordinated  Payment to the Guarantee  Trustee or any
Holder prohibited by the foregoing provisions of this Section,  then and in such
event  such  Guarantee  Subordinated  Payment  shall be paid over and  delivered
forthwith to the Designated Senior Holders under the Senior  Indebtedness or, if
such Senior Indebtedness has been repaid in full, to the Guarantor.
             The  provisions  of this Section  shall not apply to any  Guarantee
Subordinated  Payment  with  respect  to  which  Section  7.2  hereof  would  be
applicable.

             SECTION 7.4 Payment Permitted If No Default.  Nothing con
                         -------------------------------
tained in this Article or elsewhere in this  Guarantee  Agreement  shall prevent
the Guarantor, at any time except during the pendency of any Proceeding referred
to in  Section  7.2 hereof or under the  conditions  described  in  Section  7.3
hereof, from making Guarantee Subordinated Payments.

             SECTION 7.5 Subrogation To Rights Of Holders Of Senior
                         -------------------------------------------
Indebtedness.  Subject to the payment in full in cash of all Senior
- ------------
Indebtedness,  the Holders  shall be  subrogated to the rights of the holders of
such Senior Indebtedness to receive payments and distributions of cash, property
and securities  applicable to the Senior Indebtedness until the principal of and
interest  on the  Guarantee  shall  be  paid  in  full.  For  purposes  of  such
subrogation,  no  payments  or  distributions  to  the  holders  of  the  Senior
Indebtedness  of any cash,  property or  securities  to which the Holders or the
Guarantee  Trustee would be entitled  except for the provisions of this Article,
and no payments  pursuant to the  provisions  of this  Article to the holders of
Senior  Indebtedness  by Holders or the Guarantee  Trustee,  shall, as among the
Guarantor,  its  creditors  other than  holders of Senior  Indebtedness  and the
Holders,  be deemed to be a payment or  distribution  by the  Guarantor to or on
account of the Senior Indebtedness.

             SECTION 7.6 Provisions Solely To Define Relative Rights.  
The  provisions  of this Article are and are intended  solely for the purpose of
defining the  relative  rights of the Holders on the one hand and the holders of
Senior  Indebtedness  on the other hand.  Nothing  contained  in this Article or
elsewhere in this  Guarantee  Agreement  is intended to or shall (a) impair,  as
among the Guarantor,  its creditors (other than holders of Senior  Indebtedness)
and the  Holders,  the  obligation  of the  Guarantor,  which  is  absolute  and
unconditional  (and  which,  subject  to the rights  under  this  Article of the
holders of Senior  Indebtedness,  is  intended  to rank  equally  with all other
general  obligations  of the  Guarantor),  to pay to the Holders  the  Guarantee
Subordinated  Payments  as and when the same  shall  become  due and  payable in
accordance  with their  terms;  or (b) affect the  relative  rights  against the
Guarantor of the Holders and creditors of the Guarantor,  other than the holders
of Senior  Indebtedness;  or (c) prevent the Guarantee  Trustee or a Holder from
exercising all remedies otherwise permitted by applicable law upon default under
this Guarantee  Agreement,  subject to the rights, if any, under this Article of
the holders of Senior  Indebtedness  to receive  cash,  property and  securities
otherwise  payable or  deliverable  to the Guarantee  Trustee or such Holder or,

             SECTION 7.7 Guarantee Trustee To Effectuate Subordination.
                         ----------------------------------------------
Each Holder of the Guarantee by his  acceptance  thereof  authorizes and directs
the  Guarantee  Trustee on his behalf to take such action as may be necessary or
appropriate  to  effectuate  the  subordination  provided  in this  Article  and
appoints  the  Guarantee  Trustee  his  attorney-in-fact  for any  and all  such
purposes, including, in the event of any dissolution, winding-up, liquidation or
reorganization of the Guarantor whether in bankruptcy, insolvency,  receivership
proceedings,  or otherwise,  the timely filing of a claim for the unpaid balance
of the  Indebtedness  of the Guarantor owing to such Holder in the form required
in such  proceedings  and the  causing  of such  claim  to be  approved.  If the
Guarantee  Trustee  does  not file a proper  claim at least 30 days  before  the
expiration  of the time to file  such  claim,  then the  holders  of the  Senior
Indebtedness and their agents,  trustees or other representatives are authorized
to do so (but shall in no event be liable  for any  failure to do so) for and on
behalf of the Holders.

             SECTION 7.8 No Waiver Of Subordination Provisions.  No right
                         -------------------------------------
of  any  present  or  future  holder  of  any  Senior  Indebtedness  to  enforce
subordination  as herein  provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Guarantor or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the  Guarantor  with the  terms,  provisions  and  covenants  of this  Guarantee
Agreement,  regardless of any  knowledge  thereof any such holder may have or be
otherwise charged with.

             Without  in any  way  limiting  the  generality  of  the  foregoing
paragraph,  the holders of Senior Indebtedness may, at any time and from time to
time,  without the consent of or notice to the Guarantee Trustee or the Holders,
without  incurring  responsibility  to the  Holders  and  without  impairing  or
releasing  the  subordination  provided  in  this  Article  or  the  obligations
hereunder of the Holders to the holders of the Senior  Indebtedness,  do any one
or more of the  following:  (i) change the manner,  place or terms of payment or
extend  the time of  payment  of, or renew or  alter,  Senior  Indebtedness,  or
otherwise  amend  or  supplement  in  any  manner  Senior  Indebtedness  or  any
instrument  evidencing the same or any agreement under which Senior Indebtedness
is outstanding; (ii) permit the Guarantor to borrow, repay and then reborrow any
or all of the Senior Indebtedness;  (iii) sell,  exchange,  release or otherwise
deal  with  any  property  pledged,   mortgaged  or  otherwise  securing  Senior
Indebtedness; (iv) release any Person liable in any manner for the collection of
Senior Indebtedness;  (v) exercise or refrain from exercising any rights against
the Guarantor and any other Person;  and (vi) apply any sums received by them to
Senior Indebtedness.

             SECTION 7.9 Notice To Guarantee Trustee.  The Guarantor shall
- ----------------------------
give prompt  written  notice to the  Guarantee  Trustee of any fact known to the
Guarantor  which would prohibit the making of any payment to or by the Guarantee
Trustee in respect  of the  Guarantee.  Notwithstanding  the  provision  of this
Article  or any other  provision  of this  Guarantee  Agreement,  the  Guarantee
Trustee shall not be charged with  knowledge of the existence of any facts which
would  prohibit  the  making of any  payment to or by the  Guarantee  Trustee in
respect  of the  Guarantee,  unless  and  until  a  Responsible  Officer  of the
Guarantee Trustee shall have received written notice thereof from the Guarantor,
any holder of Senior  Indebtedness,  any  Designated  Senior  Holder or from any
trustee,  fiduciary or agent  therefore;  and,  prior to the receipt of any such
written notice, the Guarantee Trustee, subject to the provisions of Section 3.1,
shall be entitled in all respects to assume that no such facts exist;  provided,
however, that
                                                 --------
if the Guarantee Trustee shall not have received the notice provided for in this
Section at least three  Business  Days prior to the date upon which by the terms
hereof  any  money  may  become  payable  for any  purpose  (including,  without
limitation, the payment of any amounts due under the Guarantee),  then, anything
herein  contained  to the  contrary  notwithstanding,  but without  limiting the
rights and  remedies  of the  holders  of Senior  Indebtedness  or any  trustee,
fiduciary or agent  therefor,  the  Guarantee  Trustee shall have full power and
authority  to receive  such money and to apply the same to the purpose for which
such money was  received and shall not be affected by any notice to the contrary
which may be received by it within three  Business Days prior to such date.  Any
notice required or permitted to be given to the Guarantee Trustee by a holder of
Senior  Indebtedness or by any Designated  Senior Holder shall be in writing and
shall be  sufficient  for every  purpose  hereunder if in writing and either (i)
sent via  facsimile  to the  Guarantee  Trustee,  the  receipt of which shall be
confirmed via telephone, or (ii) mailed, first class postage prepaid, or sent by
overnight  carrier,  to the Guarantee  Trustee addressed to it at the address of
its  principal  office  specified  herein or at any other  address  furnished in
writing to such holder of Senior Indebtedness by the Guarantee Trustee.

             Subject to the  provisions  of Section 3.1, the  Guarantee  Trustee
shall be entitled to rely on the delivery to it of a written  notice by a Person
representing  himself to be a holder of Senior Indebtedness or Designated Senior
Holder (or a trustee, fiduciary or agent therefor) to establish that such notice
has been given by a holder of Senior  Indebtedness  or Designated  Senior Holder
(or a trustee,  fiduciary or agent  therefor).  In the event that the  Guarantee
Trustee  determines in good faith that further evidence is required with respect
to the right of any  Person as a holder of  Senior  Indebtedness  or  Designated
Senior Holder to  participate  in any payment or  distribution  pursuant to this
Article,  the Guarantee  Trustee may request such Person to furnish  evidence to
the reasonable  satisfaction of the Guarantee Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article, and if such evidence is not furnished,
the  Guarantee  Trustee may defer any payment to such  Person  pending  judicial
determination as to the right of such Person to receive such payment.

             Notwithstanding  anything else contained herein, no notice, request
or other  communication  to or with the Guarantee  Trustee shall be deemed given
unless received by a Responsible  Officer at the Guarantee  Trustee's  principal
corporate trust office.

provisions  of Section 3.1,  and the Holders  shall be entitled to rely upon any
order or decree  entered by any court of  competent  jurisdiction  in which such
Proceeding is pending, or a certificate of the trustee in bankruptcy,  receiver,
liquidating trustee, custodian,  assignee for the benefit of creditors, agent or
other Person  making such payment or  distribution,  delivered to the  Guarantee
Trustee or to the Holders,  for the purpose of ascertaining the Persons entitled
to  participate  in such  payment  or  distribution,  the  holders of the Senior
Indebtedness  and other  Indebtedness  of the  Guarantor,  the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts  pertinent  thereto or to this Article,  provided that the foregoing shall
apply only if such court has been apprised of the provisions of this Article.

             SECTION 7.11 Guarantee Trustee Not Fiduciary For Holders Of
                          ----------------------------------------------
Senior  Indebtedness.  The  Guarantee  Trustee  shall  not be  deemed to owe any
- -------------------  fiduciary  duty to the holders of Senior  Indebtedness  and
shall not be liable to any such holders if it shall in good faith mistakenly pay
over or  distribute  to Holders or to the Guarantor or to any other Person cash,
property  or  securities  to which any holders of Senior  Indebtedness  shall be
entitled by virtue of this Article or otherwise.

in this Article with respect to any Senior Indebtedness which may at any time be
held by it, to the same extent as any other holder of Senior  Indebtedness,  and
nothing in this Guarantee  Agreement shall deprive the Guarantee  Trustee of any
of its rights as a holder of Senior Indebtedness.

             Nothing in this  Article  shall apply to claims of, or payments to,
the Guarantee  Trustee under or pursuant to this Guarantee  Agreement or Section
6.7 of the Indenture.

             SECTION 7.13 Article Applicable to Paying Agents.  In case at
- -----------------------------------
any time any Paying  Agent  other  than the  Guarantee  Trustee  shall have been
appointed by the Guarantor  and be then acting  hereunder,  the term  "Guarantee
Trustee"  as  used in this  Article  shall  in such  case  (unless  the  context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Guarantee  Trustee;
provided, however, that Section 7.11
                                --------  -------
hereof shall not apply to the  Guarantor or any Affiliate of the Guarantor if it
or such Affiliate acts as Paying Agent.

foregoing,  this  Guarantee  Agreement  will continue to be effective or will be
reinstated,  as the  case  may be,  if at any time  any  Holder  of  Partnership
Preferred Securities must restore payment of any sums paid under the Partnership
Preferred Securities or under this Guarantee Agreement.
