Delaware corporation (the "Corporation"), is offering to exchange (the "Exchange
Offer") any and all of its outstanding  10.00% Capital  Securities  (Liquidation
Amount $1,000 per Capital Security) (the "Original Capital  Securities") for its

Security) (the "Exchange Capital  Securities").  All of the beneficial interests
represented by common securities of the Trust are owned by the Corporation.  The
terms and  conditions of the Exchange  Offer as currently  contemplated  are set
forth  in a  prospectus,  dated  _____,  1998 (as the  same  may be  amended  or
supplemented  from time to time,  the  "Prospectus"),  to be  distributed to all
record holders of the Original Capital  Securities.  A copy of the Prospectus is
attached hereto as Exhibit A. The Original  Capital  Securities and the Exchange
Capital  Securities  are  collectively  referred to herein as the  "Securities."
Capitalized  terms used but not defined herein shall have the same meaning given
them in the Prospectus.

          A copy of each of the form of the Letter of  Transmittal,  the form of
the Notice of Guaranteed Delivery, the form of letter to brokers and the form of
letter to clients are attached hereto as Exhibit B.

          The Trust hereby appoints  Wilmington Trust Company to act as exchange
agent (the "Exchange  Agent") in connection with the Exchange Offer.  References
hereinafter to "you" shall refer to Wilmington Trust Company.

          The  Exchange  Offer is  expected to be  commenced  by the Trust on or
about ________,  1998. The Letter of Transmittal accompanying the Prospectus (or
in the case of book  entry  securities,  the ATOP  system)  is to be used by the
holders of the Original  Capital  


                                       



Securities to accept the Exchange Offer and contains  instructions  with respect
to (a) the delivery of certificates for Original Capital Securities  tendered in
connection  therewith  and (b) the  book-entry  transfer  of  Securities  to the
Exchange Agent's account.

          The Exchange  Offer shall  expire at 5:00 p.m.,  New York City time, o
____________, 1998 or on such later date or time to which the Corporation or the
Trust may extend the  Exchange  Offer (the  "Expiration  Date").  Subject to the
terms and conditions set forth in the Prospectus,  the Trust expressly  reserves
the right to extend the  Exchange  Offer from time to time by giving oral (to be
confirmed in writing) or written  notice to you before 9:00 a.m.,  New York City
time, on the Business Day following the previously scheduled Expiration Date.

          The  Trust  expressly  reserves  the right to amend or  terminate  the
Exchange Offer, and not to accept for exchange any Original  Capital  Securities
not  theretofore  accepted  for  exchange,  upon  the  occurrence  of any of the
conditions of the Exchange Offer  specified in the Prospectus  under the caption
"The Exchange  Offer --  Conditions to the Exchange  Offer." The Trust will give
you prompt  oral  (confirmed  in writing)  or written  notice of any  amendment,
termination or nonacceptance of Original Capital Securities.

          In  carrying  out your  duties as  Exchange  Agent,  you are to act in
accordance with the following instructions:

          1.  You  will  perform  such  duties  and  only  such  duties  as  are
specifically set forth in the section of the Prospectus  captioned "The Exchange
Offer" or as specifically set forth herein;  provided,  however,  that in no way
will your general duty to act in good faith be discharged by the foregoing.

          2. You will establish an account with respect to the Original  Capital
Securities at The Depository Trust Company (the "Book-Entry  Transfer Facility")
for  purposes of the Exchange  Offer within two Business  Days after the date of
the  Prospectus,  and any financial  institution  that is a  participant  in the
Book-Entry  Transfer  Facility's  system  may make  book-entry  delivery  of the
Original  Capital  Securities  by causing the  Book-Entry  Transfer  Facility to
transfer such Original  Capital  Securities into your account in accordance with
the Book-Entry Transfer Facility's procedure for such transfer.

          3.  You  are  to  examine  each  of the  Letters  of  Transmittal  and
certificates  for Original  Capital  Securities (or  confirmation  of book-entry
transfer into your account at the  Book-Entry  Transfer  Facility) and any other
documents  delivered or mailed to you by or for holders of the Original  Capital
Securities to ascertain  whether:  (a) the Letters of  Transmittal  and any such
other  documents  are duly executed and properly  completed in  accordance  with
instructions  set forth  therein and (b) the Original  Capital  Securities  have
otherwise been properly  tendered.  In each case where the Letter of Transmittal
or any other  document has been  improperly  completed or executed or any of the
certificates for Original Capital 



                                       


Securities  are not in proper form for  transfer or some other  irregularity  in
connection  with the acceptance of the Exchange Offer exists,  you will endeavor
to inform such holders of the need for  fulfillment of all  requirements  and to
take  any  other  action  as  may  be  necessary  or  advisable  to  cause  such
irregularity to be corrected.

          4. With the approval of any  Administrator  of the Trust or any person
designated  in  writing  by  the  Corporation  (a  "Designated  Officer")  (such
approval,  if given  orally,  to be  confirmed  in  writing)  or any other party
designated by any such Administrator or Designated  Officer in writing,  you are
authorized to waive any irregularities in connection with any tender of Original
Capital Securities pursuant to the Exchange Offer.

          5.  Tenders of  Original  Capital  Securities  may be made only as set
forth  in  the  Letter  of  Transmittal  and in the  section  of the  Prospectus
captioned  "The Exchange  Offer -- Procedures  for  Tendering  Original  Capital
Securities,"  and  Original  Capital  Securities  shall be  considered  properly
tendered to you only when tendered in accordance  with the  procedures set forth
therein.

          Notwithstanding  the  provisions  of  this  paragraph  five,  Original
Capital  Securities that any Administrator of the Trust or Designated Officer of
the  Corporation  shall  approve  as  having  been  properly  tendered  shall be
considered to be properly  tendered.  Such approval,  if given orally,  shall be
confirmed in writing.

          6. You shall advise the Trust and the Corporation  with respect to any
Original  Capital  Securities  received  subsequent to the  Expiration  Date and
accept their  instructions  with respect to disposition of such Original Capital
Securities.

          7. You shall accept tenders:

    (a)   in cases where the Original  Capital  Securities are registered in two
    or more names only if signed by all named holders;

    (b)   in cases  where the  signing  person  (as  indicated  on the Letter of
    Transmittal) is acting in a fiduciary or a representative capacity only when
    proper evidence of such person's authority so to act is submitted; and

    (c)   from  persons  other than the  registered  holder of Original  Capital
    Securities   provided  that  customary  transfer   requirements,   including
    satisfaction of any applicable transfer taxes, are fulfilled.

          You shall accept partial tenders of Original Capital  Securities where
so  indicated  and as  permitted  in  the  Letter  of  Transmittal  and  deliver
certificates for Original Capital  Securities to the transfer agent for division
and return any  



                                       


untendered  Original  Capital  Securities to the holder (or such other person as
may be designated in the Letter of Transmittal) as promptly as practicable after
expiration or termination of the Exchange Offer.

          8.  Upon  satisfaction  or  waiver  of all of  the  conditions  to the
Exchange Offer, the Trust will notify you (such notice,  if given orally,  to be
confirmed in writing) of its acceptance,  promptly after the Expiration Date, of
all  Original  Capital  Securities  properly  tendered and you, on behalf of the
Trust,  will exchange  such Original  Capital  Securities  for Exchange  Capital
Securities and cause such Original Capital  Securities to be canceled.  Delivery
of Exchange Capital Securities will be made on behalf of the Trust by you at the
rate of $1,000 principal  amount of Exchange Capital  Securities for each $1,000
principal  amount of the  corresponding  series of Original  Capital  Securities
tendered promptly after notice (such notice, if given orally, to be confirmed in
writing)  of  acceptance  of said  Original  Capital  Securities  by the  Trust;
provided,  however,  that in all cases,  Original  Capital  Securities  tendered
pursuant to the Exchange  Offer will be exchanged  only after timely  receipt by
you of certificates  for such Original  Capital  Securities (or  confirmation of
book-entry transfer into your account at the Book-Entry  Transfer  Facility),  a
properly  completed  and duly  executed  Letter  of  Transmittal  (or  facsimile
thereof)  with  any  required  signature   guarantees  and  any  other  required
documents.  You shall issue Exchange Capital Securities only in denominations of
$1,000 or any integral  multiple  thereof.  Original  Capital  Securities may be
tendered in whole or in part in denominations of $100,000 and integral multiples
of $1,000 in excess thereof,  provided that if any Original  Capital  Securities
are tendered for exchange in part, the untendered  principal amount thereof must
be $100,000 or any integral multiple of $1,000 in excess thereof.

          9. Tenders  pursuant to the  Exchange  Offer are  irrevocable,  except
that,  subject to the terms and upon the  conditions set forth in the Prospectus
and the Letter of Transmittal,  Original Capital Securities tendered pursuant to
the Exchange  Offer may be  withdrawn at any time on or prior to the  Expiration
Date.

          10. The Trust shall not be required to exchange any  Original  Capital
Securities tendered if any of the conditions set forth in the Exchange Offer are
not met.  Notice  of any  decision  by the Trust not to  exchange  any  Original
Capital Securities  tendered shall be given orally (and confirmed in writing) by
the Trust to you.

          11. If, pursuant to the Exchange Offer,  the Trust does not accept for
exchange all or part of the Original Capital  Securities  tendered because of an
invalid  tender,  the  occurrence  of  certain  other  events  set  forth in the
Prospectus  under the caption "The Exchange  Offer -- Conditions to the Exchange
Offer" or otherwise,  you shall  promptly after the expiration or termination of
the Exchange Offer return those  certificates  for unaccepted  Original  Capital
Securities  (or  effect  appropriate  book-entry  transfer),  together  with any
related required documents and 






the Letters of Transmittal relating thereto that are in your possession,  to the
persons who deposited them.

          12.  All  certificates  for  reissued  Original  Capital   Securities,
unaccepted  Original Capital Securities or for Exchange Capital Securities shall
be forwarded (a) by first-class certified mail, return receipt requested,  under
a  blanket  surety  bond  protecting  you and the Trust  from loss or  liability
arising out of the  non-receipt or  non-delivery  of such  certificates;  (b) by
registered  mail insured  separately for the  replacement  value of each of such
certificates or (c) by effectuating appropriate book-entry transfer.

          13.  You are not  authorized  to pay or offer to pay any  concessions,
commissions or solicitation fees to any broker, dealer, bank or other persons or
to engage or utilize any person to solicit tenders.

          14. As Exchange Agent hereunder you:

         (a) shall have no duties or obligations  other than those  specifically
         set forth in the  section of the  Prospectus  captioned  "The  Exchange
         Offer," the Letter of Transmittal  or herein or as may be  subsequently
         agreed to in writing by you and the Trust;

         (b) will be  regarded  as  making  no  representations  and  having  no
         responsibilities as to the validity,  sufficiency, value or genuineness
         of  any  of  the  certificates  or  the  Original  Capital   Securities
         represented  thereby deposited with you pursuant to the Exchange Offer,
         and will not be required to and will make no  representation  as to the
         validity,  value or  genuineness of the Exchange Offer or the Letter of
         Transmittal or any other disclosure  materials  delivered in connection
         therewith;

         (c) shall not be  obligated to take any legal  action  hereunder  which
         might in your  reasonable  judgment  involve any expense or  liability,
         unless  you  shall  have  been  furnished  with  indemnity   reasonably
         satisfactory to you;

         (d) may reasonably rely on and shall be protected in acting in reliance
         upon any certificate,  instrument, opinion, notice, letter, telegram or
         other document or security delivered to you and reasonably  believed by
         you to be  genuine  and to have  been  signed  by the  proper  party or
         parties;

         (e) may reasonably act upon any tender, statement,  request,  agreement
         or other  instrument  whatsoever  not only as to its due  execution and
         validity and effectiveness of its provisions,  but also as to the truth
         and accuracy of any information  contained therein,  which you shall in
         good faith believe to be genuine or to have been signed or  represented
         by a proper person or persons;


         (f) may rely on and shall be  protected  in acting upon written or oral
         instructions from any Administrator of the Trust or from any Designated
         Officer of the Corporation;

         (g) may consult with counsel satisfactory to you, including counsel for
         the Trust,  with respect to any  questions  relating to your duties and
         responsibilities  and the advice or opinion  of such  counsel  shall be
         full and complete authorization and protection in respect of any action
         taken,  suffered or omitted to be taken by you  hereunder in good faith
         and in accordance with the advice or opinion of such counsel,  provided
         that you shall promptly  notify the  Corporation of any action taken or
         omitted by you in reliance upon such advice or opinion; and

         (h) shall not advise any person tendering  Original Capital  Securities
         pursuant to the  Exchange  Offer as to the wisdom of making such tender
         or as to the market value or decline or appreciation in market value of
         any Original Capital Securities.

          15. You shall take such  action as may from time to time be  requested
by the Trust or its counsel or any Designated  Officer of the  Corporation  (and
such other action as you may reasonably  deem  appropriate) to furnish copies of
the Prospectus,  Letter of Transmittal and the Notice of Guaranteed  Delivery or
such  other  forms  as may be  approved  from  time to time by the  Trust or the
Corporation,  to all persons  requesting such documents and to accept and comply
with telephone requests for information relating to the Exchange Offer, provided
that such  information  shall relate only to the  procedures  for  accepting (or
withdrawing  from) the Exchange Offer. The Trust will furnish you with copies of
such documents at your request.  All other requests for information  relating to
the Exchange Offer shall be directed to the Trust, Attention: Peter J. Swiatek.

          16. You shall  advise by  facsimile  transmission  or  telephone,  and
promptly  thereafter  confirm in writing to Peter J.  Swiatek of the Trust,  and
such other person or persons as the Trust or the Corporation may request,  daily
(and more frequently  during the week immediately  preceding the Expiration Date
and if otherwise  requested) up to and including the Expiration  Date, as to the
number of Original Capital  Securities which have been tendered  pursuant to the
Exchange  Offer  and the  items  received  by you  pursuant  to this  Agreement,
separately  reporting and giving cumulative totals as to items properly received
and items improperly received. In addition,  you will also inform, and cooperate
in making available to, the Trust or the Corporation or any such other person or
persons,  upon oral request made from time to time on or prior to the Expiration
Date,  such other  information as it or such person  reasonably  requests.  Such
cooperation shall include, without limitation,  the granting by you to the Trust
or the Corporation, and such person as the Trust or the Corporation may request,
of access to those  persons  on your  staff who are  responsible  for  receiving
tenders,  in order to ensure 



that immediately prior to the Expiration Date the Trust or the Corporation shall
have received information in sufficient detail to enable it to decide whether to
extend the Exchange  Offer.  You shall prepare a final list of all persons whose
tenders  were  accepted,  the  aggregate  principal  amount of Original  Capital
Securities  tendered,   the  aggregate  principal  amount  of  Original  Capital
Securities  accepted  and  deliver  said  list to the Trust  promptly  after the
Expiration Date.

          17. Letters of Transmittal and Notices of Guaranteed Delivery shall be
stamped  by you as to the date  and the time of  receipt  thereof  and  shall be
preserved  by you for a period of time at least  equal to the period of time you
preserve other records pertaining to the transfer of securities.

          18.  You  hereby  expressly  waive any lien,  encumbrance  or right of
set-off  whatsoever  that you may have with respect to funds  deposited with you
for the payment of transfer taxes by reasons of amounts, if any, borrowed by the
Trust, or any of its  subsidiaries or affiliates  pursuant to any loan or credit
agreement with you or for compensation owed to you hereunder.

          19. For services  rendered as Exchange Agent  hereunder,  you shall be
entitled  to the  compensation  set forth on  Schedule I attached  hereto,  plus
reasonable  out-of-pocket  expenses and reasonable  attorneys' fees, incurred in
connection with your services hereunder, within 30 days following receipt by the
Corporation  of an itemized  statement of such  expenses and fees in  reasonable
detail.

          20.  (a) The Trust  covenants  and  agrees to  indemnify  and hold you
(which for purposes of this paragraph shall include your directors, officers and
employees)  harmless  in your  capacity  as Exchange  Agent  hereunder  from and
against any and all loss, liability,  cost, damage, expense and claim, including
but not limited to reasonable attorneys' fees and expenses, incurred by you as a
result of, arising out of or in connection  with the  performance by you of your
duties under this Agreement or the compliance by you with the  instructions  set
forth herein or delivered hereunder; provided, however, that the Trust shall not
be liable  for  indemnification  or  otherwise  for any loss,  liability,  cost,
damage,  expense  or claim  arising  out of your  gross  negligence  or  willful
misconduct.  In no case  shall the Trust be liable  under  this  indemnity  with
respect to any claim  against  you unless the Trust shall be notified by you, by
letter or by facsimile  confirmed by letter, of the written assertion of a claim
against you or of any other action  commenced  against you,  promptly  after you
shall have  received any such written  assertion  or notice of  commencement  of
action.  The Trust shall be entitled  to  participate  at its own expense in the
defense  of any such claim or other  action,  and,  if the Trust so elects,  the
Trust may assume  the  defense of any suit  brought to enforce  any such  claim;
provided  that the Trust shall not be entitled to assume the defense of any such
action if the named  parties to such action  include  both the Trust and you and
representation  of both parties by the same legal counsel would,  in the written



opinion  of  counsel  to  you,  be  inappropriate  due to  actual  or  potential
conflicting interests between them. If the Trust shall assume the defense of any
such suit or threatened action in respect of which indemnification may be sought
hereunder,  the  Trust  shall  not be liable  for the fees and  expenses  of any
counsel  thereafter  retained by you.  The Trust shall not be liable  under this
paragraph for the fees and expenses of more than one legal counsel for you.

          (b) You agree  that,  without the prior  written  consent of the Trust
(which  consent  shall  not be  unreasonably  withheld),  you will  not  settle,
compromise or consent to the entry of any pending or threatened  claim,  action,
or proceeding in respect of which  indemnification could be sought in accordance
with the indemnification provisions of this Agreement (whether or not you or the
Trust or any of its  trustees or  controlling  persons is an actual or potential
party to such claim, action or proceeding),  unless such settlement,  compromise
or consent includes an  unconditional  release of the Trust and its trustees and
controlling  persons  from all  liability  arising out of such claim,  action or
proceeding.

          21. You shall  arrange to comply with all  requirements  under the tax
laws  of  the  United   States,   including   those   relating  to  missing  Tax
Identification Numbers, and shall file any appropriate reports with the Internal
Revenue  Service.  The  Trust  understands  that  you are  required  in  certain
instances to deduct 31% of the amounts to be paid with respect to interest  paid
on the  Exchange  Capital  Securities  and  proceeds  from the  sale,  exchange,
redemption  or retirement of the Exchange  Capital  Securities  from holders who
have not  supplied  their  correct  Taxpayer  Identification  Number or required
certification. Such funds will be turned over to the Internal Revenue Service in
accordance with applicable regulations.

          22. You shall  notify the Trust of the  amount of any  transfer  taxes
payable in respect of the  exchange of Original  Capital  Securities  and,  upon
receipt of written  approval  from the Trust,  you shall  deliver or cause to be
delivered,  in a timely  manner  to each  governmental  authority  to which  any
transfer  taxes are  payable in  respect of the  exchange  of  Original  Capital
Securities,  your check in the amount of all transfer taxes so payable,  and the
Trust shall  reimburse you for the amount of any and all transfer  taxes payable
in respect of the exchange of Original Capital  Securities;  provided,  however,
that you shall  reimburse  the Trust for  amounts  refunded to you in respect of
your payment of any such transfer taxes, at such time as such refund is received
by you.

          23 This Agreement and your  appointment  as Exchange  Agent  hereunder
shall be  construed  and  enforced in  accordance  with the laws of the State of
Delaware  applicable to agreements made and to be performed entirely within such
state, and without regard to conflicts of law principles, and shall inure to the
benefit  of, and the  obligations  created  hereby  shall be binding  upon,  the
successors 



and assigns of each of the parties  hereto,  and no other  person shall have any
rights hereunder.

          24. This Agreement may be executed in one or more  counterparts,  each
of which shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

          25. In case any provision of this Agreement shall be invalid,  illegal
or  unenforceable,  the validity,  legality and  enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

          26. This  Agreement  shall not be deemed or  construed to be modified,
amended, rescinded, canceled or waived, in whole or in part, except by a written
instrument  signed  by a  duly  authorized  representative  of the  party  to be
charged. This Agreement may not be modified orally.

          27. Unless otherwise provided herein, all notices,  requests and other
