waived any Event of Default with respect to the Common Securities and its
consequences until all Events of Default with respect to the Preferred
Securities have been cured, waived by the Holders of Preferred Securities as
provided in this Declaration or otherwise eliminated and until all Events of
Default with respect to the Preferred Securities have been so cured, waived or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of the Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Property Trustee in
accordance with the terms of this Declaration or the Securities. In the event
that any Event of Default with respect to the Preferred Securities is waived by
the Holders of Preferred Securities as


                                       11
   17

provided in this Declaration, the Holders of Common Securities agree that such
waiver shall also constitute the waiver of such Event of Default with respect to
the Common Securities for all purposes under this Declaration without any
further act, vote or consent of the Holders of the Common Securities. Subject to
the foregoing provisions of this Section 2.06(b), upon such waiver, any such
default shall cease to exist and any Event of Default with respect to the Common
Securities arising therefrom shall be deemed to have been cured for every
purpose of this Declaration, but no such waiver shall extend to any subsequent
or other default or Event of Default with respect to the Common Securities or
impair any right consequent thereon.

Distributions on the Securities in accordance with this Declaration and the

consent of such Holder.

      (d) As provided in the terms of the Securities set forth in Exhibits B and

deemed to be a violation of any existing law, or any law hereafter enacted which
does not specifically refer to ss. 312 of the Trust Indenture Act, nor shall the
Property Trustee be held accountable by reason of mailing any material pursuant

3.10(g) being hereby defined to be an Indenture Event of Default, not including
any periods of grace provided for in the Indenture and irrespective of the
giving of any notice provided therein); provided, that, except in the case of

any of the Debentures, the Property Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust committee of directors and/or Responsible Officers, of the Property
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of the Securities. The Property Trustee shall not be
deemed to have knowledge of any default, except (i) a default in the payment of

            (ii) a Successor Property Trustee has been appointed and accepted
      that appointment in accordance with Article 5.

      Distributions, redemption payments or liquidation payments on behalf of
      the Trust with respect to the Preferred Securities. Any such Paying Agent
      shall comply with ss. 317(b) of the Trust Indenture Act. Any Paying Agent
      may be removed by the Property Trustee, after consultation with the
      Regular Trustees, at any time and a successor Paying Agent or additional
      Paying Agents may be appointed at any time by the Property Trustee,
      subject to Section 3.08(r).

payments of interest on the Debentures by extending the interest payment period
with respect thereto.

      (k) Subject to this Section 3.10, the Property Trustee shall have none of
the powers or the authority of the Regular Trustees set forth in Section 3.08.

      (l) The Property Trustee shall exercise the powers, duties and rights set

after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this

against the Property Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.06, the Property Trustee shall

affairs.

      (b) No provision of this Declaration shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that:

      curing or waiving of all such Events of Default that may have occurred:

                  (A) the duties and obligations of the Property Trustee shall
            be determined solely by the express provisions of this Declaration,
            and the Property Trustee shall not be liable except for the
            performance of such duties and obligations as are specifically set
            forth in this Declaration, and no implied covenants or obligations
            shall be read into this Declaration against the Property Trustee;
            and

                  (B) in the absence of bad faith on the part of the Property
            Trustee, the Property Trustee may conclusively rely, as to the truth
            of the statements and the correctness of the opinions expressed
            therein, upon any certificates or opinions furnished to the Property
            Trustee and conforming to the requirements of this Declaration; but
            in the case of any such certificates or opinions that by any
            provision hereof are specifically required to be furnished to the
            Property Trustee, the Property Trustee shall be under a duty to
            examine the same to determine whether or not they conform to the
            requirements of this Declaration;

            (ii) the Property Trustee shall not be liable for any error of
      judgment made in good faith by a Responsible Officer of the Property
      Trustee, unless it shall be proved that the Property Trustee was negligent
      in ascertaining the pertinent facts;

            (iii) the Property Trustee shall not be liable with respect to any
      action taken or omitted to be taken by it in good faith in accordance with
      the direction of the Holders as provided herein relating to the time,
      method and place of conducting any proceeding for any remedy available to
      the Property Trustee hereunder or under the Indenture, or exercising any
      trust or power conferred upon the Property Trustee under this Declaration;
      and

            (iv) no provision of this Declaration shall require the Property
      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 it shall have reasonable
      ground for believing that the repayment of such funds or liability is not
      reasonably assured to it under the terms of this Declaration or adequate
      indemnity against such risk or liability is not reasonably assured to it.

      (c) Subject to the provisions of Sections 3.12(a) and 3.12(b):

            (i) whenever in the administration of this Declaration, the Property
      Trustee shall deem it desirable that a matter be proved or


                                       23
   29

      established prior to taking, suffering or omitting any action hereunder,
      the Property Trustee (unless other evidence is herein specifically
      prescribed) may, in the absence of bad faith on its part and, if the Trust
      is excluded from the definition of Investment Company solely by means of
      Rule 3a-7, subject to the requirements of Rule 3a-7, request and rely upon
      a certificate, which shall comply with the provisions of ss. 314(e) of the
      Trust Indenture Act, signed by any two of the Regular Trustees or by an
      authorized officer of the Sponsor, as the case may be;

            (ii) The Property Trustee (A) may consult with counsel (which may be
      counsel to the Sponsor or any of its Affiliates and may include any of its
      employees) selected by it in good faith and with due care and the written
      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 reliance
      thereon and in accordance with such advice and opinion and (B) shall have
      the right at any time to seek instructions concerning the administration
      of this Declaration from any court of competent jurisdiction;

            (iii) The Property Trustee may execute any of the trusts or powers
      hereunder or perform any duties hereunder either directly or by or through
      agents or attorneys and the Property Trustee shall not be responsible for
      any misconduct or negligence on the part of any agent or attorney
      appointed by it in good faith and with due care;

            (iv) The Property Trustee shall be under no obligation to exercise
      any of the rights or powers vested in it by this Declaration at the
      request or direction of any Holders, unless such Holders shall have
      offered to the Property Trustee reasonable security and indemnity against
      the costs, expenses (including attorneys' fees and expenses) and
      liabilities that might be incurred by it in complying with such request or
      direction; provided that nothing contained in this clause (iv) shall
      relieve the Property Trustee of the obligation, upon the occurrence of an
      Event of Default (which has not been cured or waived) to exercise such of
      the rights and powers vested in it by this Declaration, and to use the
      same degree of care and skill in this exercise, as a prudent person would
      exercise or use under the circumstances in the conduct of his or her own
      affairs; and

            (v) Any action taken by the Property Trustee or its agents hereunder
      shall bind the Holders of the Securities and the signature of the Property
      Trustee or its agents alone shall be sufficient and effective to perform
      any such action; and no third party shall be required to inquire as


                                       24
   30

      to the authority of the Property Trustee to so act, or as to its
      compliance with any of the terms and provisions of this Declaration, both
      of which shall be conclusively evidenced by the Property Trustee's or its
      agent's taking such action.

            and has accepted such appointment by instrument executed by such
            Successor Property Trustee and delivered to the Trust, the Sponsor
            and the resigning Property Trustee; or

                  (B) if the Trust is excluded from the definition of an
            Investment Company solely by reason of Rule 3a-7, until the assets
            of the Trust have been completely liquidated and the proceeds
            thereof distributed to the Holders of the Securities; and

            (ii) no such resignation of the Trustee that acts as the Delaware
      Trustee shall be effective until a Successor Delaware Trustee has been
      appointed and has accepted such appointment by instrument executed by such
      Successor Delaware Trustee and delivered to the Trust, the Sponsor and the
      resigning Delaware Trustee.

      (e) If no Successor Property Trustee or Successor Delaware Trustee shall
have been appointed and accepted appointment as provided in this Section 5.02
within 60 days after delivery to the Sponsor and the Trust of a Resignation
Request, the resigning Property Trustee or Delaware Trustee may petition any
court of competent jurisdiction for appointment of a Successor Property Trustee


                                       31
   37

or Successor Delaware Trustee. Such court may thereupon after such notice, if
any, as it may deem proper and prescribe, appoint a Successor Property Trustee
or Successor Delaware Trustee, as the case may be.

      SECTION 5.03. Vacancies among Trustees.

      If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 5.01 or if the number of Trustees is
increased pursuant to Section 5.01, a vacancy shall occur. A resolution
certifying the existence of such vacancy by a majority of the Regular Trustees
shall be conclusive evidence of the existence of such vacancy. The vacancy shall
be filled with a Trustee appointed in accordance with the requirements of this
Article 5.

      SECTION 5.04. Effect of Vacancies.

      The death, resignation, retirement, removal, bankruptcy, dissolution,
liquidation, incompetence or incapacity to perform the duties of a Trustee, or
any one of them, shall not operate to annul the Trust. Whenever a vacancy in the
number of Regular Trustees shall occur until such vacancy is filled as provided
in this Article 5, the Regular Trustees in office, regardless of their number,
shall have all the powers granted to the Regular Trustees and shall discharge
all the duties imposed upon the Regular Trustees by this Declaration.

      SECTION 5.05. Meetings.

      Meetings of the Regular Trustees shall be held from time to time upon the
call of any Trustee. Regular meetings of the Regular Trustees may be held at a
time and place fixed by resolution of the Regular Trustees. Notice of any in-
person meeting of the Regular Trustees shall be hand delivered or otherwise
delivered in writing (including by facsimile, with a hard copy by overnight
courier) not less than 48 hours before such meeting. Notice of any telephonic
meeting of the Regular Trustees or any committee thereof shall be hand delivered
or otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 24 hours before such meeting. Notices shall
contain a brief statement of the time, place and anticipated purposes of the
meeting. The presence (whether in person or by telephone) of a Regular Trustee
at a meeting shall constitute a waiver of notice of such meeting except where a
Regular Trustee attends a meeting for the express purpose of objecting to the
transaction of any activity on the ground that the meeting has not been lawfully
called or convened. Unless provided otherwise in this Declaration, any action of
the Regular Trustees may be taken at a meeting by vote of a majority of the
Regular Trustees present (whether in person or by telephone) and eligible to
vote


                                       32
   38
 with respect to such matter; provided that a Quorum is present, or without a
meeting by the unanimous written consent of the Regular Trustees.

      SECTION 5.06. Delegation of Power.

     (a) Any Regular Trustee may, by power of attorney consistent with
applicable law, delegate to any other natural person over the age of 21 his or
her power for the purpose of executing any registration statement or amendment
thereto or other document or schedule filed with the Commission or making any
other governmental filing (including, without limitation to filings referred to
in Section 3.13).

     (b) The Regular Trustees shall have power to delegate from time to time to
such of their number or to officers of the Trust the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Regular Trustees or otherwise as the Regular Trustees may deem expedient,
to the extent such delegation is not prohibited by applicable law or contrary to
the provisions of the Trust, as set forth herein.

   
      SECTION 5.07. Other Activities.

      Subject to Section 5.01(c) (with respect to the Property Trustee), the
Sponsor and any 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 shall
have no rights by virtue of this Declaration in and to such independent ventures
or the income or 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. Neither the Sponsor, nor any 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 the Sponsor or any 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 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 Sponsory for, trustee or agent
for, or act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.

                                  DISTRIBUTIONS

      SECTION 6.01. Distributions.

      Holders shall receive periodic distributions, redemption payments and
liquidation distributions in accordance with the applicable terms of the
relevant Holder's Securities ("Distributions"). Distributions shall be made to
the Holders of Preferred Securities and Common Securities in accordance with the
terms of the Securities as set forth in Exhibits B and C hereto. If and to the
extent that Services makes a payment of interest (including Compounded Interest
(as defined in the Indenture)), premium and principal on the Debentures held by
the Property Trustee (the amount of any such payment being a "Payment Amount"),
the Property Trustee shall and is directed to promptly make a Distribution of
the Payment Amount to Holders in accordance with the terms of the Securities as
set forth in Exhibits B and C hereto.

                             ISSUANCE OF SECURITIES

      SECTION 7.01. General Provisions Regarding Securities.

      (a) The Regular Trustees shall issue on behalf of the Trust securities in
fully registered form representing undivided beneficial interests in the assets
of the Trust in accordance with Section 7.01(b) and for the consideration
specified in Section 3.03.

      (b) The Regular Trustees shall issue on behalf of the Trust one class of
preferred securities representing undivided beneficial interests in the assets
of the Trust having such terms as are set forth in Exhibit B (the "Preferred
Securities") which terms are incorporated by reference in, and made a part of,
this Declaration as if specifically set forth herein, and one class of common
securities representing undivided beneficial interests in the assets of the
Trust having such terms as are set forth in Exhibit C (the "Common Securities")
which terms are incorporated by reference in, and made a part of, this
Declaration as if specifically set forth herein. The Trust shall have no
securities or other interests in the assets of the Trust other than the
Preferred Securities and the Common Securities.

      (c) The Certificates shall be signed on behalf of the Trust by the Regular
Trustees (or if there are more than two Regular Trustees by any two of the
Regular Trustees). Such signatures may be the manual or facsimile signatures of
the present or any future Regular Trustee. Typographical and other minor errors
or defects in any such reproduction of any such signature shall not affect the
validity of any Certificate. In case any Regular Trustee of the Trust who shall
have signed any of the Certificates shall cease to be such Regular Trustee
before the Certificate so signed shall be delivered by the Trust, such
Certificate nevertheless may be delivered as though the person who signed such
Certificate had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons as, at the actual date of the
execution of such Certificate, shall be the Regular Trustees of the Trust,
although at the date of the execution and delivery of the Declaration any such
person was not such a Regular Trustee. Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or


                                       34
   40

regulation of any stock exchange on which Securities may be listed, or to
conform to usage. Pending the preparation of definitive Certificates, the
Regular Trustees on behalf of the Trust may execute temporary Certificates
(printed, lithographed or typewritten), in substantially the form of the
definitive Certificates in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Certificates, all as may be determined by the Regular Trustees. Each temporary
Certificate shall be executed by the Regular Trustees on behalf of the Trust
upon the same conditions and in substantially the same manner, and with like
effect, as definitive Certificates. Without unnecessary delay, the Regular
Trustees on behalf of the Trust will execute and furnish definitive Certificates
and thereupon any or all temporary Certificates may be surrendered to the
transfer agent and registrar in exchange therefor (without charge to the
Holders). Each Certificate whether in temporary or definitive form shall be
countersigned by the manual or facsimile signature of an authorized signatory of
the Person acting as registrar and transfer agent for the Securities, which
shall initially be the Property Trustee.

      (d) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

      (e) Upon issuance of the Securities as provided in this Declaration, the
Securities so issued shall be deemed to be validly issued, fully paid and
non-assessable.

      (f) Every Person, by virtue of having become a Holder or a Preferred
Security Beneficial Owner in accordance with the terms of this Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by this Declaration.

      (g) Upon issuance of the Securities as provided in this Declaration, the
Regular Trustees on behalf of the Trust shall return to Services the $10
constituting initial trust assets as set forth in the Original Declaration.

                              TERMINATION OF TRUST

      SECTION 8.01. Termination of Trust.


                                       35
   41

      This Declaration and the Trust shall terminate and be of no further force
or effect when:

            (i) all of the Securities shall have been called for redemption and
      the amounts necessary for redemption thereof shall have been paid to the
      Holders of Securities in accordance with the terms of the Securities; or

            (ii) all of the Debentures shall have been distributed to the
      Holders of Securities in exchange for all of the Securities in accordance
      with the terms of the Securities; or

            (iii) upon the expiration of the term of the Trust as set forth in
      Section 3.17,

and a certificate of cancellation is filed by the Trustees with the Secretary of
State of the State of Delaware. The Trustees shall so file such a certificate as
soon as practicable after the occurrence of an event referred to in this Section
8.01.

      The provisions of Sections 3.12 and 4.02 and Article 10 shall survive the
termination of the Trust.

                                    ARTICLE 9

                              TRANSFER OF INTERESTS

      SECTION 9.01. Transfer of Securities.

      (a) Securities may only be transferred, in whole or in part, in accordance
with the terms and conditions set forth in this Declaration. Any transfer or
purported transfer of any Security not made in accordance with this Declaration
shall be null and void.

      (b) Subject to this Article 9, Preferred Securities shall be freely
transferable.

      (c) Subject to this Article 9, Services and any Related Party may only
transfer Common Securities to Services or a Related Party; provided that any
such transfer shall be subject to the condition that the transferor shall have
obtained (1) either a ruling from the Internal Revenue Service or an unqualified
written opinion addressed to the Trust and delivered to the Trustees of
nationally recognized independent tax counsel experienced in such matters to the
effect that


                                       36
   42

such transfer will not (i) cause the Trust to be treated as issuing a class of
interests in the Trust differing from the class of interests represented by the
Common Securities originally issued to Services, (ii) result in the Trust
acquiring or disposing of, or being deemed to have acquired or disposed of, an
asset, or (iii) result in or cause the Trust to be treated as anything other
than a grantor trust for United States federal income tax purposes and (2) an
unqualified written opinion addressed to the Trust and delivered to the Trustees
of a nationally recognized independent counsel experienced in such matters that
such transfer will not cause the Trust to be an Investment Company or controlled
by an Investment Company.

      SECTION 9.02. Transfer of Certificates.

      The Regular Trustees shall provide for the registration of Certificates
and of transfers of Certificates, which will be effected without charge but only
upon payment (with such indemnity as the Regular Trustees may require) in
respect of any tax or other government charges which may be imposed in relation
to it. Upon surrender for registration of transfer of any Certificate, the
Regular Trustees shall cause one or more new Certificates to be issued in the
name of the designated transferee or transferees. Every Certificate surrendered
for registration of transfer shall be accompanied by a written instrument of
transfer in form satisfactory to the Regular Trustees duly executed by the
Holder or such Holder's attorney duly authorized in writing. Each Certificate
surrendered for registration of transfer shall be canceled by the Regular
Trustees. A transferee of a Certificate shall be entitled to the rights and
subject to the obligations of a Holder hereunder upon the receipt by such
transferee of a Certificate. By acceptance of a Certificate, each transferee
shall be deemed to have agreed to be bound by this Declaration.

      SECTION 9.03. Deemed Security Holders.

      The Trustees may treat the Person in whose name any Certificate shall be
registered on the books and records of the Trust as the sole holder of such
Certificate and of the Securities represented by such Certificate for purposes
of receiving Distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities represented by such
Certificate on the part of any Person, whether or not the Trustees shall have
actual or other notice thereof.


                                       37
   43

      SECTION 9.04. Book Entry Interests.

      Unless otherwise specified in the terms of the Preferred Securities, the
Preferred Securities Certificates, on original issuance (including Preferred
Securities, if any, issued on the Option Closing Date pursuant to the exercise
of the over allotment option set forth in the Underwriting Agreement), will be
issued in the form of one or more, fully registered, global Preferred Security
Certificates (each a "Global Certificate"), to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Trust. Such Global Certificates shall
initially be registered on the books and records of the Trust in the name of
Cede & Co., the nominee of DTC, and no Preferred Security Beneficial Owner will
receive a definitive Preferred Security Certificate representing such Preferred
Security Beneficial Owner's interests in such Global Certificates, except as
provided in Section 9.07. Unless and until definitive, fully registered
Preferred Security Certificates (the "Definitive Preferred Security
Certificates") have been issued to the Preferred Security Beneficial Owners
pursuant to Section 9.07:

            (i) the provisions of this Section 9.04 shall be in full force and
      effect;

            (ii) the Trust and the Trustees shall be entitled to deal with the
      Clearing Agency for all purposes of this Declaration (including the
      payment of Distributions on the Global Certificates and receiving
      approvals, votes or consents hereunder) as the Holder of the Preferred
      Securities and the sole holder of the Global Certificates and, except as
      set forth herein or in Rule 3a-7 with respect to the Property Trustee,
      shall have no obligation to the Preferred Security Beneficial Owners;

            (iii) to the extent that the provisions of this Section 9.04
      conflict with any other provisions of this Declaration, the provisions of
      this Section 9.04 shall control; and

   
            (iv) the rights of the Preferred Security Beneficial Owners shall be
      exercised only through the Clearing Agency and shall be limited to those
      established by law and agreements between such Preferred Security
      Beneficial Owners and the Clearing Agency and/or the Clearing Agency
      Participants; provided, that solely for the purposes of determining
      whether the Holders of the requisite amount of Preferred Securities have
      voted on any matter provided for in this Declaration, so long as
      Definitive Preferred Security Certificates have not been issued, the
      Trustees may conclusively rely on, and shall be protected in relying on,
      any written instrument (including a proxy) delivered to the Trustees by
      the Depository setting forth the Preferred Security Beneficial Owners'
      votes or assigning the right to vote on any matter to any other Persons
      either in whole or in part. DTC will make book entry transfers among the
      Clearing Agency Participants and receive and transmit payments of
      Distributions on the Global Certificates to such Clearing Agency
      Participants.
    

      SECTION 9.05. Notices to Holders of Certificates.


                                       38
   44

      Whenever a notice or other communication to the Holders is required to be
given under this Declaration, unless and until Definitive Preferred Security
Certificates shall have been issued pursuant to Section 9.07, the relevant
Trustees shall give all such notices and communications, specified herein to be
given to Preferred Securities Holders, to the Clearing Agency and, with respect
to any Preferred Security Certificate registered in the name of a Clearing
Agency or the nominee of a Clearing Agency, the Trustees shall, except as set
forth herein or in Rule 3a-7 with respect to the Property Trustee, have no
notice obligations to the Preferred Security Beneficial Owners.

      SECTION 9.06. Appointment of Successor Clearing Agency.

      If any Clearing Agency elects to discontinue its services as securities
depository with respect to the Preferred Securities, the Regular Trustees may,
in their sole discretion, appoint a successor Clearing Agency with respect to
the Preferred Securities.

      SECTION 9.07. Definitive Preferred Securities Certificates.

      If (i) a Clearing Agency elects to discontinue its services as securities
depository with respect to the Preferred Securities and a successor Clearing
Agency is not appointed within 90 days after such discontinuance pursuant to
Section 9.06 or (ii) the Regular Trustees elect after consultation with the
Sponsor to terminate the book entry system through the Clearing Agency with
respect to the Preferred Securities, then (x) Definitive Preferred Security
Certificates shall be prepared by the Regular Trustees on behalf of the Trust
with respect to such Preferred Securities and (y) upon surrender of the Global
Certificates by the Clearing Agency, accompanied by registration instructions,
the Regular Trustees shall cause definitive Preferred Security Certificates to
be delivered to Preferred Security Beneficial Owners in accordance with the
instructions of the Clearing Agency. Neither the Trustees nor the Trust shall be
liable for any delay in delivery of such instructions and each of them may
conclusively rely on and shall be protected in relying on, such instructions.

      SECTION 9.08. Mutilated, Destroyed, Lost or Stolen Certificates.

      If (a) any mutilated Certificates should be surrendered to the Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and (b) there
shall be delivered to the Regular Trustees such security or indemnity as may be
required by them to keep each of them harmless, then in the absence of notice
that such Certificate shall have been acquired by a bona fide purchaser, any two
Regular Trustees on behalf of the Trust shall execute and deliver, in exchange
for or in lieu of any such


                                       39
   45

mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination. In connection with the issuance of any new Certificate under this
Section 9.08, the Regular Trustees may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

                                   ARTICLE 10

                    LIMITATION OF LIABILITY; INDEMNIFICATION

      SECTION 10.01. 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, 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 (but, in the
case of the Property Trustee, subject to Section 2.01) 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 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.

      (c) Pursuant to ss. 3803(a) of the Business Trust Act, the Holders of
Securities, in their capacities as Holders, shall be entitled to the same
limitation of liability that is extended to stockholders of private corporations
for profit organized under the General Corporation Law of the State of Delaware.

      SECTION 10.02. Indemnification.

      (a) To the fullest extent permitted by applicable law, the Sponsor shall
indemnify and hold harmless each Indemnified Person from and against any loss,
damage or claim incurred by such Indemnified Person 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 authority conferred on such Indemnified Person by this
Declaration, except that no Indemnified Person shall be entitled to be
indemnified in respect of any loss, damage or claim incurred by such Indemnified
Person by reason of gross negligence (or, in the case of the Property Trustee,
negligence) or willful misconduct with respect to such acts or omissions.

      (b) To the fullest extent permitted by applicable law, expenses (including
legal fees) incurred by an Indemnified Person in defending any claim, demand,
action, suit or proceeding shall, from time to time, be advanced by the Sponsor
prior to the final disposition of such claim, demand, action, suit or proceeding
upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified
Person to repay such amount if it shall be determined that the Indemnified
Person is not entitled to be indemnified as authorized in Section 10.02(a).

   
      (c) The provisions of this Section 10.02 shall survive the termination of
this Declaration or the resignation or removal of any Trustee.

      SECTION 11.01. Fiscal Year.

      The fiscal year ("Fiscal Year") of the Trust shall be the calendar year,

      SECTION 11.02. Certain Accounting Matters.

      (a) At all times during the existence of the Trust, the Regular Trustees
shall keep, or cause to be kept, full books of account, records and supporting
documents, which shall reflect in reasonable detail, each transaction of the
Trust. The books of account shall be maintained on the accrual method of
accounting, in accordance with generally accepted accounting principles,
consistently applied. The Trust shall use the accrual method of accounting for
United States federal income tax purposes. The books and records of the Trust,
together with a copy of this Declaration and a certified copy of the Certificate
of Trust, or any amendment


                                       41

and shall be open for inspection for any examination by any Holder or its duly
authorized representative for any purpose reasonably related to its interest in
the Trust during normal business hours.

      (b) The Regular Trustees shall, as soon as available after the end of each
Fiscal Year of the Trust, cause to be prepared and mailed to each Holder of
Securities unaudited financial statements of the Trust for such Fiscal Year,
prepared in accordance with generally accepted accounting principles; provided
that if the Trust is required to comply with the periodic reporting requirements
of Sections 13(a) or 15(d) of the Exchange Act, such financial statements for
such Fiscal Year shall be examined and reported on by a firm of independent
certified public accountants selected by the Regular Trustees (which firm may be
the firm used by the Sponsor).

      (c) The Regular Trustees shall cause to be prepared and mailed to each
Holder of Securities, an annual United States federal income tax information
statement, on such form as is required by the Code, containing such information
with regard to the Securities held by each Holder as is required by the Code and
the Treasury Regulations. Notwithstanding any right under the Code to deliver
any such statement at a later date, the Regular Trustees shall endeavor to

state or local taxing authority, such returns to be filed as soon as practicable
after the end of each Fiscal Year of the Trust.

      SECTION 11.03. Banking.

      The Trust shall maintain one or more bank accounts in the name and for the
sole benefit of the Trust; provided, however, that all payments of funds in
respect of the Debentures held by the Property Trustee shall be made directly to
the Property Account and no other funds from the Trust shall be deposited in the
Property Account. The sole signatories for such accounts shall be designated by
the Regular Trustees; provided, however, that the Property Trustee shall
designate the sole signatories for the Property Account.

the Holders shall provide to the Trust, such forms or certificates as are
necessary to establish an exemption from withholding with respect to each
Holder, and any representations and forms as shall reasonably be requested by
the Trust to assist it in determining the extent of, and in fulfilling, its
withholding obligations. The Trust shall file required forms with applicable
jurisdictions and, unless an exemption from withholding is properly established
by a Holder, shall remit amounts withheld with respect to the Holder to
applicable jurisdictions. To the extent that the Trust is required to withhold
and pay over any amounts to any authority with respect to distributions or
allocations to any Holder, the amount withheld shall be deemed to be a
distribution in the amount of the withholding to the Holder. In the event of any
claimed over withholding, Holders shall be limited to an action against the
applicable jurisdiction. If the amount to be withheld was not withheld from a
Distribution, the Trust may reduce subsequent Distributions by the amount of
such withholding.

9.1(c) and this Section 12.01 shall not be amended without the consent of all

rights, powers and privileges of the Property Trustee or the Delaware Trustee
shall be made without the consent of the Property Trustee or the Delaware
Trustee, as the case may be, (v) Article 4 shall not be amended without the

under Article 5 to increase or decrease the number of, and to appoint, replace

      (b) Notwithstanding Section 12.02(b)(ii), this Declaration may be amended
without the consent of the Holders of the Securities to (i) cure any ambiguity,
(ii) correct or supplement any provision in this Declaration that may be
defective or inconsistent with any other provision of this Declaration, (iii) to

      SECTION 12.02. Meetings of the Holders of Securities; Action by Written
Consent.

   
      (a) Meetings of the Holders of Preferred Securities and/or Common
Securities may be called at any time by the Regular Trustees (or as provided in
the terms of the Securities) to consider and act on any matter on which Holders
of such class of Securities are entitled to act under the terms of this
Declaration, the terms of the Securities or the rules of any stock exchange on
which the Preferred Securities are listed or admitted for trading. The Regular
Trustees shall call a meeting of Holders of Preferred Securities or Common
Securities, if directed to do so by Holders of at least 25% in liquidation
amount of such class of Securities. Such direction shall be given by delivering
to the Regular Trustees one or more calls in a writing stating that the signing
Holders of Securities wish to call a meeting and indicating the general or
specific purpose for which the meeting is to be called. Any Holders of
Securities calling a meeting shall specify in writing the Certificates held by
the Holders of Securities exercising the right to call a meeting and only those
specified Certificates shall be counted for purposes of determining whether the
required percentage set forth in the second sentence of this paragraph has been
met.
    

      (b) Except to the extent otherwise provided in the terms of the
Securities, the following provision shall apply to meetings of Holders of
Securities:


                                       44
   50

            (i) Notice of any such meeting shall be given by mail to all the
      Holders of Securities having a right to vote thereat not less than 7 days
      nor more than 60 days prior to the date of such meeting. Whenever a vote,
      consent or approval of the Holders of Securities is permitted or required
      under this Declaration or the rules of any stock exchange on which the
      Preferred Securities are listed or admitted for trading, such vote,
      consent or approval may be given at a meeting of the Holders of
      Securities. Any action that may be taken at a meeting of the Holders of
      Securities may be taken without a meeting if a consent in writing setting
      forth the action so taken is signed by Holders of Securities owning not
      less than the minimum aggregate liquidation amount of Securities that
      would be necessary to authorize or take such action at a meeting at which
      all Holders of Securities having a right to vote thereon were present and
      voting. Prompt notice of the taking of action without a meeting shall be
      given to the Holders of Securities entitled to vote who have not consented
      in writing. The Regular Trustees may specify that any written ballot
      submitted to the Holders of Securities for the purpose of taking any
      action without a meeting shall be returned to the Trust within the time
      specified by the Regular Trustees.

            (ii) Each Holder of a Security may authorize any Person to act for
      it by proxy on all matters in which a Holder of a Security is entitled to
      participate, including waiving notice of any meeting, or voting or
      participating at a meeting. No proxy shall be valid after the expiration
      of 11 months from the date thereof unless otherwise provided in the proxy.
      Every proxy shall be revocable at the pleasure of the Holder of the
      Security executing it. Except as otherwise provided herein or in the terms
      of the Securities, all matters relating to the giving, voting or validity
      of proxies shall be governed by the General Corporation Law of the State
      of Delaware relating to proxies, and judicial interpretations thereunder,
      as if the Trust were a Delaware corporation and the Holders of the
      Securities were stockholders of a Delaware corporation.

            (iii) Each meeting of the Holders of the Securities shall be
      conducted by the Regular Trustees or by such other Person that the Regular
      Trustees may designate.

            (iv) Unless otherwise provided in the Business Trust Act, this
      Declaration or the rules of any stock exchange on which the Preferred
      Securities are then listed or admitted for trading, the Regular Trustees,
      in their sole discretion, shall establish all other provisions relating to
      meetings of Holders of Securities, including notice of the time, place or
      purpose of any meeting at which any matter is to be voted on by any


                                       45

      Holders of Securities, waiver of any such notice, action by consent
      without a meeting, the establishment of a record date, quorum
      requirements, voting in person or by proxy or any other matter with

                                    TERMS OF
                              PREFERRED SECURITIES

      Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust
of Aetna Capital Trust [ ] dated as of ____________, 199__ (as amended from time
to time, the "Declaration"), the designations, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities are set
forth below (each capitalized term used but not defined herein having the
meaning set forth in the Declaration):

      1. Designation and Number. Preferred Securities of the Trust with an
aggregate liquidation amount in the assets of the Trust of
___________________________________________ Dollars ($___________) (including up
to _______________________________________________ Dollars ($___________)
issuable upon exercise of the over allotment option set forth in the
Underwriting Agreement) and a liquidation amount in the assets of the Trust of
$25 per Preferred Security, are hereby designated as "____% Preferred Trust
Securities". The Preferred Security Certificates evidencing the Preferred
Securities shall be substantially in the form attached hereto as Annex I, with
such changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice or to conform to the rules of any stock
exchange on which the Preferred Securities are listed. In connection with the
issuance and sale of the Preferred Securities and the Common Securities, the
Trust will purchase as trust assets Debentures of Services having an aggregate
principal amount equal to the aggregate liquidation amount of the Preferred
Securities and Common Securities so issued and bearing interest at an annual
rate equal to the annual Distribution rate on the Preferred Securities and
Common Securities and having payment and redemption provisions which correspond
to the payment and redemption provisions of the Preferred Securities and Common
Securities.

   
      2. Distributions. (a) Distributions payable on each Preferred Security
will be fixed at a rate per annum of ____% (the "Coupon Rate") of the stated
liquidation amount of $25 per Preferred Security. Distributions in arrears for
more than one month will bear interest at the rate per annum of ____% thereof
(to the extent permitted by law), compounded [monthly]. The term "Distributions"
as used in these terms means such periodic cash distributions and any such
interest payable unless otherwise stated. A Distribution will be made by the
Property Trustee only to the extent that interest payments are made in respect
of the Debentures held by the Property Trustee. The amount of Distributions
payable
    
   64
   
for any period will be computed for any [monthly] Distribution period on the
basis of a 360-day year of twelve 30-day months[, and for any Distribution
period shorter or longer than a 30-day month Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed].
    

   
      (b) Distributions on the Preferred Securities will be cumulative, will
accrue from ___________, 199__ and will be payable [monthly] in arrears, on the
last day of each month commencing on ________________, 199__, except as
otherwise described below, but only if and to the extent that interest payments
are made in respect of the Debentures held by the Property Trustee. So long as
Services shall not be in default in the payment of interest on the Debentures,
Services has the right under the Indenture for the Debentures to defer payments
of interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding [60] consecutive [monthly] interest
periods (each, an "Extension Period") and, as a consequence, [monthly]
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the rate of ____% per annum, compounded
[monthly] during any such Extension Period. Prior to the termination of any such
Extension Period, Services may further extend such Extension Period; provided
that such Extension Period together with all such previous and further
extensions thereof may not exceed [60] consecutive [monthly] interest periods.
Upon the termination of any Extension Period and the payment of all amounts then
due, Services may commence a new Extension Period, subject to the above
requirements. Payments of accrued Distributions will be payable to Holders of
Preferred Securities as they appear on the books and records of the Trust on the
first record date after the end of the Extension Period.
    

      (c) Distributions on the Preferred Securities will be payable promptly by
the Property Trustee (or other Paying Agent) upon receipt of immediately
available funds to the Holders thereof as they appear on the books and records
of the Trust on the relevant record dates. While the Preferred Securities remain
in book-entry only form, the relevant record dates shall be one business day
prior to the relevant Distribution date, and if the Preferred Securities are no
longer in book-entry only form, the relevant record dates will be the fifteenth
(15th) day of the month prior to the relevant Distribution date, which record
and payment dates correspond to the record and interest payment dates on the
Debentures. Distributions payable on any Preferred Securities that are not
punctually paid on any Distribution payment date as a result of Services having
failed to make the corresponding interest payment on the Debentures will
forthwith cease to be payable to the person in whose name such Preferred
Security is registered on the relevant record date, and such defaulted
Distribution will instead be payable to the person in whose name such Preferred
Security is registered on the special record


                                       2
   65

date established by the Regular Trustees, which record date shall correspond to
the special record date or other specified date determined in accordance with
the Indenture; provided, however, that Distributions shall not be considered
payable on any Distribution payment date falling within an Extension Period
unless Services has elected to make a full or partial payment of interest
accrued on the Debentures on such Distribution payment date. Subject to any
applicable laws and regulations and the provisions of the Declaration, each
payment in respect of the Preferred Securities will be made as described
paragraph 9 hereof. If any date on which Distributions are payable on the
Preferred Securities is not a Business Day, then payment of the Distribution
payable on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay)
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.

      (d) All Distributions paid with respect to the Preferred Securities and
the Common Securities will be paid Pro Rata to the Holders thereof entitled
thereto. If an Event of Default has occurred and is continuing, the Preferred
Securities shall have a priority over the Common Securities with respect to
Distributions.

      (e) In the event that there is any money or other property held by or for
the Trust that is not accounted for under the Declaration, such money or
property shall be distributed Pro Rata among the Holders of the Preferred
Securities and Common Securities.

      3. Liquidation Distribution Upon Dissolution. In the event of any
voluntary or involuntary dissolution, winding-up or termination of the Trust,
the Holders of the Preferred Securities and Common Securities at the date of the
dissolution, winding-up or termination, as the case may be, will be entitled to
receive Pro Rata solely out of the assets of the Trust available for
distribution to Holders of Preferred Securities and Common Securities after
satisfaction of liabilities to creditors as provided by applicable law, an
amount equal to the aggregate of the stated liquidation amount of $25 per
Preferred Security and Common Security plus accrued and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless, in connection with such dissolution, winding-up or
termination, and after satisfaction of liabilities to creditors as provided by
applicable law, Debentures in an aggregate principal amount equal to the
aggregate stated liquidation amount of such Preferred Securities and Common
Securities and bearing accrued and unpaid interest in an amount equal to the
accrued and unpaid Distributions on, such Preferred Securities and Common
Securities, shall be distributed Pro Rata to the


                                       3
   66

Holders of the Preferred Securities and Common Securities in exchange for such
Securities.

      If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred Securities and Common Securities shall be paid, subject
to the next paragraph, on a Pro Rata basis.

      Holders of Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution Pro Rata with Holders of Preferred
Securities, except that if an Event of Default has occurred and is continuing,
the Preferred Securities shall have a priority over the Common Securities with
respect to such Liquidation Distribution.

      4. Redemption and Distribution of Debentures. The Preferred Securities and
Common Securities may only be redeemed if Debentures having an aggregate
principal amount equal to the aggregate liquidation amount of the Preferred
Securities and Common Securities are repaid, redeemed or distributed as set
forth below:

      (a) Upon the repayment of the Debentures, in whole or in part, whether at
maturity, upon redemption at any time or from time to time on or after
_________, 20__, the proceeds of such repayment will be promptly applied to
redeem Pro Rata Preferred Securities and Common Securities having an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
repaid or redeemed, upon not less than 30 nor more than 60 days' notice, at a
redemption price of $25 per Preferred and Common Security plus an amount equal
to accrued and unpaid Distributions thereon to the date of redemption, payable
in cash (the "Redemption Price"). The date of any such repayment or redemption
of Preferred Securities and Common Securities shall be established to coincide
with the repayment or redemption date of the Debentures.

      (b) If fewer than all the outstanding Preferred Securities and Common
Securities are to be so redeemed, the Preferred Securities and the Common
Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed
as described in paragraph 4(f)(ii) below. If a partial redemption would result
in the delisting of the Preferred Securities by any national securities exchange
or other organization on which the Preferred Securities are then listed,
Services pursuant to the Indenture will only redeem Debentures in whole and, as
a result, the Trust may only redeem the Preferred Securities in whole.


                                       4
   67

      (c) If, at any time, a Tax Event or an Investment Company Event (each as
hereinafter defined, and each a "Special Event") shall occur and be continuing,
the Regular Trustees shall, unless the Debentures are redeemed in the limited
circumstances described below, dissolve the Trust and, after satisfaction of
creditors as provided by applicable law, cause Debentures held by the Property
Trustee having an aggregate principal amount equal to the aggregate stated
liquidation amount of and accrued and unpaid interest equal to accrued and
unpaid Distributions on, and having the same record date for payment as the
Preferred Securities and Common Securities, to be distributed to the Holders of
the Preferred Securities and Common Securities on a Pro Rata basis in
liquidation of such Holders' interests in the Trust, within 90 days following
the occurrence of such Special Event (the "90 Day Period"; provided, however,
that in the case of the occurrence of a Tax Event, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on any then
applicable published revenue ruling of the Internal Revenue Service, to the
effect that the Holders of the Preferred Securities will not recognize any gain
or loss for United States federal income tax purposes as a result of the
dissolution of the Trust and distribution of Debentures; and provided, further,
that, if and as long as at the time there is available to the Trust the
opportunity to eliminate, within the 90 Day Period, the Special Event by taking
some ministerial action, such as filing a form or making an election, or
pursuing some other similar reasonable measure that has no adverse effect on the
Trust, Services, Aetna or the Holders of the Preferred Securities ("Ministerial
Action"), the Trust will pursue such measure in lieu of dissolution.

      If in the case of the occurrence of a Tax Event, (i) the Regular Trustees
have received an opinion (a "Redemption Tax Opinion") of nationally recognized
independent tax counsel experienced in such matters that, as a result of a Tax
Event, there is more than an insubstantial risk that Services would be precluded
from deducting the interest on the Debentures for United States federal income
tax purposes even if the Debentures were distributed to the Holders of Preferred
Securities and Common Securities in liquidation of such Holder's interest in the
Trust as described in this paragraph 4(c) or (ii) the Regular Trustees shall
have been informed by such tax counsel that a No Recognition Opinion cannot be
delivered to the Trust, Services shall have the right at any time, upon not less
than 30 nor more than 60 days' notice, to redeem the Debentures in whole or in
part for cash at the Redemption Price within 90 days following the occurrence of
such Tax Event, and promptly following such redemption Preferred Securities and
Common Securities with an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so redeemed will be redeemed by the Trust at
the Redemption Price on a Pro Rata basis; provided, however, that,


                                       5
   68

if at the time there is available to Services or the Regular Trustees on behalf
of the Trust the opportunity to eliminate, within such 90 day period, the Tax
Event by taking some Ministerial Action, Services or the Regular Trustees on
behalf of the Trust will pursue such measure in lieu of redemption and;
provided, further, that Services shall have no right to redeem the Debentures
while the Regular Trustees on behalf of the Trust are pursuing such Ministerial
Action. The Common Securities will be redeemed Pro Rata with the Preferred
Securities, except that if an Event of Default under the Indenture has occurred
and is continuing, the Preferred Securities will have a priority over the Common
Securities with respect to payment of the Redemption Price.

      "Tax Event" means that the Regular Trustees shall have obtained an opinion
of nationally recognized independent tax counsel experienced in such matters (a
"Dissolution Tax Opinion") to the effect that on or after ____________, 199_ as
a result of (a) any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein, (b) any amendment
to, or change in, an interpretation or application of any such laws or
regulations by any legislative body, court, governmental agency or regulatory
authority (including the enactment of any legislation and the publication of any
judicial decision or regulatory determination), (c) any interpretation or
pronouncement that provides for a position with respect to such laws or
regulations that differs from the theretofore generally accepted position or (d)
any action taken by any governmental agency or regulatory authority, which
amendment or change is enacted, promulgated, issued or announced or which
interpretation or pronouncement is issued or announced or which action is taken,
in each case on or after _________, 199_, there is more than an insubstantial
risk that (i) the Trust is, or will be within 90 days of the date thereof,
subject to United States federal income tax with respect to income accrued or
received on the Debentures, (ii) the Trust is, or will be within 90 days of the
date thereof, subject to more than a de minimis amount of taxes, duties or other
governmental charges or (iii) interest payable by Services to the Trust on the
Debentures is not, or within 90 days of the date thereof will not be, deductible
by Services for United States federal income tax purposes.

      "Investment Company Event" means that the Regular Trustees shall have
received an opinion of nationally recognized independent counsel experienced in
practice under the Investment Company Act that, as a result of the occurrence of
a change in law or regulation or a change in interpretation or application of
law or regulation by any legislative body, court, governmental agency or
regulatory authority (a "Change in 1940 Act Law"), there is more than an
insubstantial risk that the Trust is or will be considered an Investment


                                       6
   69

Company which is required to be registered under the Investment Company Act,
which Change in 1940 Act Law becomes effective on or after _________, 199_.

      On the date fixed for any distribution of Debentures, upon dissolution of
the Trust, (i) the Preferred Securities will no longer be deemed to be
outstanding and (ii) certificates representing Preferred Securities will be
deemed to represent beneficial interests in the Debentures having an aggregate
principal amount equal to the stated liquidation amount of, and bearing accrued
and unpaid interest equal to accrued and unpaid Distributions on, such Preferred
Securities until such certificates are presented to Services or its agent for
transfer or reissuance.

   
      (d) The Trust may not redeem fewer than all the outstanding Preferred
Securities unless all accrued and unpaid Distributions have been paid on all
Preferred Securities for all [monthly] Distribution periods terminating on or
prior to the date of redemption.
    

      (e) If Debentures are distributed to Holders of the Preferred Securities,
Services, pursuant to the terms of the Indenture, will use its best efforts to
have the Debentures listed on the New York Stock Exchange or on such other
exchange as the Preferred Securities were listed immediately prior to the
distribution of the Debentures.

      (f) (i) Notice of any redemption of, or notice of distribution of
Debentures in exchange for, the Preferred Securities and Common Securities (a
"Redemption/Distribution Notice") will be given by the Regular Trustees on
behalf of the Trust by mail to each Holder of Preferred Securities and Common
Securities to be redeemed or exchanged not less than 30 nor more than 60 days
prior to the date fixed for redemption or exchange thereof. For purposes of the
calculation of the date of redemption or exchange and the dates on which notices
are given pursuant to this paragraph (f)(i), a Redemption/Distribution Notice
shall be deemed to be given on the day such notice is first mailed by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities. Each Redemption/Distribution Notice shall be addressed to the
Holders of Preferred Securities and Common Securities at the address of each
such Holder appearing in the books and records of the Trust. No defect in the
Redemption/Distribution Notice or in the mailing of either thereof with respect
to any Holder shall affect the validity of the redemption or exchange
proceedings with respect to any other Holder.

      (ii) In the event that fewer than all the outstanding Preferred Securities
are to be redeemed, the Preferred Securities to be redeemed will be redeemed Pro
Rata from each Holder of Preferred Securities, it being understood that, in
respect of Preferred Securities registered in the name of and held of record by
DTC (or


                                       7
   70

successor Clearing Agency) or any other nominee, the Preferred Securities will
be redeemed from, and the distribution of the proceeds of such redemption will
be made to, each Clearing Agency Participant (or person on whose behalf such
nominee holds such securities) in accordance with the procedures applied by such
agency or nominee.

      (iii) Subject to paragraph 9 hereof, if the Trust gives a Redemption/
Distribution Notice in respect of a redemption of Preferred Securities as
provided in this paragraph 4 (which notice will be irrevocable) then (A) while
the Preferred Securities are in book-entry only form, with respect to the
Preferred Securities, by 12:00 noon, New York City time, on the redemption date,
provided that Services has paid the Property Trustee, in immediately available
funds, a sufficient amount of cash in connection with the related redemption or
maturity of the Debentures, the Property Trustee will deposit irrevocably with
DTC (or successor Clearing Agency) funds sufficient to pay the applicable
Redemption Price with respect to the Preferred Securities and will give DTC (or
successor Clearing Agency) irrevocable instructions and authority to pay the
Redemption Price to the Holders of the Preferred Securities and (B) if the
Preferred Securities are issued in definitive form, with respect to the
Preferred Securities and provided that Services has paid the Property Trustee,
in immediately available funds, a sufficient amount of cash in connection with
the related redemption or maturity of the Debentures, the Property Trustee will
pay the relevant Redemption Price to the Holders of such Preferred Securities by
check mailed to the address of the relevant Holder appearing on the books and
records of the Trust on the redemption date. If a Redemption/Distribution Notice
shall have been given and funds deposited as required, if applicable, then
immediately prior to the close of business on the redemption date, Distributions
will cease to accrue on the Preferred Securities called for redemption, such
Preferred Securities will no longer be deemed to be outstanding and all rights
of Holders of such Preferred Securities so called for redemption will cease,
except the right of the Holders of such Preferred Securities to receive the
Redemption Price, but without interest on such Redemption Price. Neither the
Trustees nor the Trust shall be required to register or cause to be registered
the transfer of any Preferred Securities which have been so called for
redemption. If any date fixed for redemption of Preferred Securities is not a
Business Day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date fixed for redemption. If payment of the Redemption Price in respect
of Preferred Securities is improperly withheld or refused and not paid either by
the Property Trustee or by Services or Aetna pursuant to the Preferred
Securities Guarantee, Distributions on such Preferred Securities will continue
to accrue,


                                       8
   71

from the original redemption date to the date of payment, in which case the
actual payment date will be considered the date fixed for redemption for
purposes of calculating the Redemption Price.

      (iv) Redemption/Distribution Notices shall be sent by the Regular Trustees
on behalf of the Trust to DTC or its nominee (or any successor Clearing Agency
or its nominee) if the Global Certificates have been issued or, if Definitive
Preferred Security Certificates have been issued, to the Holders of the
Preferred Securities.

      (v) Upon the date of dissolution of the Trust and distribution of
Debentures as a result of the occurrence of a Special Event, Preferred Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so distributed, and the Preferred Securities will no longer be deemed
outstanding and may be canceled by the Regular Trustees. The Debentures so
distributed shall have an aggregate principal amount equal to the aggregate
liquidation amount of the Preferred Securities so distributed.

      (vi) Subject to the foregoing and applicable law (including, without
limitation, United States federal securities laws), Services, Aetna or any of
its subsidiaries may at any time and from time to time purchase outstanding
Preferred Securities by tender, in the open market or by private agreement.

      5. Voting Rights. (a) Except as provided under paragraph 5(b) below and as
otherwise required by law and the Declaration, the Holders of the Preferred
Securities will have no voting rights.

      (b) If any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than in connection
with the distribution of Debentures held by the Property Trustee, upon the
occurrence of a Special Event or in connection with the redemption of Preferred
Securities as a consequence of a redemption of Debentures, then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such amendment or proposal shall not be effective except with the
approval of the Holders of Securities representing 66-2/3% in liquidation amount
of such Securities; provided, however, that (A) if any amendment or proposal
referred to in clause (i) above would adversely affect only the Preferred
Securities or the Common Securities, then only the affected class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of 66-2/3% in liquidation amount
of such class of Securities and (B)


                                       9
   72

amendments to the Declaration shall be subject to such further requirements as
are set forth in Sections 12.1 and 12.2 of the Declaration.

      In the event the consent of the Property Trustee, as the holder of the
Debentures, is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the Property
Trustee shall request the written direction of the Holders of the Securities
with respect to such amendment, modification or termination. The Property
Trustee shall vote with respect to such amendment, modification or termination
as directed by a Majority in liquidation amount of the Securities voting
together as a single class; provided that where such amendment, modification or
termination of the Indenture requires the consent or vote of (1) holders of
Debentures representing a specified percentage greater than a majority in
principal amount of the Debentures or (2) each holder of Debentures, the
Property Trustee may only vote with respect to that amendment, modification or
termination as directed by, in the case of clause (1) above, the vote of Holders
of Securities representing such specified percentage of the aggregate
liquidation amount of the Securities, or, in the case of clause (2) above, each
Holder of Securities; and provided, further, that the Property Trustee shall be
under no obligation to take any action in accordance with the directions of the
Holders of Securities unless the Property Trustee shall have received, at the
expense of the Sponsor, an opinion of nationally recognized independent tax
counsel recognized as expert in such matters to the effect that the Trust will
not be classified for United States federal income tax purposes as an
association taxable as a corporation or a partnership on account of such action
and will be treated as a grantor trust for United States federal income tax
purposes following such action.

      Subject to Section 2.6 of the Declaration, and the provisions of this and
the next succeeding paragraph, the Holders of a Majority in liquidation amount
of the Preferred Securities, voting separately as a class shall have the right
to (A) on behalf of all Holders of Preferred Securities, waive any past default
that is waivable under the Declaration (subject to, and in accordance with the
Declaration) and (B) direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or exercising any
trust or power conferred upon the Property Trustee under the Declaration,
including the right to direct the Property Trustee, as the holder of the
Debentures, to (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or exercising any
trust or power conferred on the Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 6.06 of
the Indenture, or (iii) exercise any right to rescind or annul a declaration
that the principal of all the Debentures shall be due and payable; provided that
where the taking of any action under the Indenture requires the consent or vote
of (1) holders of Debentures representing a


                                       10
   73

specified percentage greater than a majority in principal amount of the
Debentures or (2) each holder of Debentures, the Property Trustee may only take
such action if directed by, in the case of clause (1) above, the vote of Holders
of Preferred Securities representing such specified percentage of the aggregate
liquidation amount of the Preferred Securities, or, in the case of clause (2)
above, each Holder of Preferred Securities. The Property Trustee shall not
revoke any action previously authorized or approved by a vote of the Holders of
the Preferred Securities. Other than with respect to directing the time, method
and place of conducting any proceeding for any remedy available to the Property
Trustee or the Debenture Trustee as set forth above, the Property Trustee shall
be under no obligation to take any of the foregoing actions at the direction of
the Holders of Preferred Securities unless the Property Trustee shall have
received, at the expense of the Sponsor, an opinion of nationally recognized
independent tax counsel recognized as expert in such matters to the effect that
the Trust will not be classified for United States federal income tax purposes
as an association taxable as a corporation or a partnership on account of such
action and will be treated as a grantor trust for United States federal income
tax purposes following such action. If the Property Trustee fails to enforce its
rights under the Declaration (including, without limitation, its rights, powers
and privileges as a holder of the Debentures under the Indenture), any Holder of
Preferred Securities may, to the extent permitted by law, after a period of 30
days has elapsed from such Holder's written request to the Property Trustee to
enforce such rights, institute a legal proceeding directly against Services and
Aetna to enforce the Property Trustee's rights under the Declaration, without
first instituting a legal proceeding against the Property Trustee or any other
Person.

      A waiver of an Indenture Event of Default by the Property Trustee at the
direction of the Holders of the Preferred Securities will constitute a waiver of
the corresponding Event of Default under the Declaration in respect of the
Securities.

      Any required approval or direction of Holders of Preferred Securities may
be given at a separate meeting of Holders of Preferred Securities convened for
such purpose, at a meeting of all of the Holders of Securities of the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Preferred Securities. Each such notice
will include a statement setting forth (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents.

      No vote or consent of the Holders of Preferred Securities will be required
for the Trust to redeem and cancel Preferred Securities in accordance with the
Declaration.

      Notwithstanding that Holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities at such time that are owned by Services or by any entity directly or
indirectly controlling or controlled by or under direct or indirect common
control with Services shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.

      Except as provided in this paragraph 5, Holders of the Preferred
Securities will have no rights to increase or decrease the number of Trustees or
to appoint, remove or replace a Trustee, which voting rights are vested solely
in the Holders of the Common Securities.

      6. Pro Rata Treatment. A reference in these terms of the Preferred
Securities to any payment, distribution or treatment as being "Pro Rata" shall
mean pro rata to each Holder of Securities according to the aggregate
liquidation amount of the Securities held by the relevant Holder in relation to
the aggregate liquidation amount of all Securities outstanding unless, in
relation to a payment, an Event of Default has occurred and is continuing, in
which case any funds available to make such payment shall be paid first to each
Holder of the Preferred Securities pro rata according to the aggregate
liquidation amount of Preferred Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Preferred Securities outstanding, and
only after satisfaction of all amounts owed to the Holders of the Preferred
Securities, to each Holder of Common Securities pro rata according to the
aggregate liquidation amount of Common Securities held by the relevant Holder
relative to the aggregate liquidation amount of all Common Securities
outstanding.

      7. Ranking. The Preferred Securities rank pari passu and payment thereon
will be made Pro Rata with the Common Securities except that where an Event of
Default occurs and is continuing, the rights of Holders of Preferred Securities
to payment in respect of Distributions and payments upon liquidation, redemption
or otherwise rank in priority to the rights of Holders of the Common Securities.

      8. Mergers, Consolidations or Amalgamations. The Trust may not
consolidate, amalgamate, merge with or into, or be replaced by, or convey,
transfer or lease its properties and assets to, any corporation or other body.


                                       12
   75

      9. Transfer, Exchange, Method of Payments. Payment of Distributions and
payments on redemption of the Preferred Securities will be payable, the transfer
of the Preferred Securities will be registrable, and Preferred Securities will
be exchangeable for Preferred Securities of other denominations of a like
aggregate liquidation amount, at the principal corporate trust office of the
Property Trustee in The City of Chicago; provided that payment of Distributions
may be made at the option of the Regular Trustees on behalf of the Trust by
check mailed to the address of the persons entitled thereto and that the payment
on redemption of any Preferred Security will be made only upon surrender of such
Preferred Security to the Property Trustee.

      10. Acceptance of Indenture and Preferred Guarantee. Each Holder of
Preferred Securities, by the acceptance thereof, agrees to the provisions of (i)
the Preferred Guarantee, including the subordination provisions therein and (ii)
the Indenture and the Debentures, including the subordination provisions of the
Indenture.

      11. No Preemptive Rights. The Holders of Preferred Securities shall have
no preemptive rights to subscribe to any additional Preferred Securities or
Common Securities.

      12. Miscellaneous. These terms shall constitute a part of the Declaration.
The Trust will provide a copy of the Declaration and the Indenture to a Holder
without charge on written request to the Trust at its principal place of
business.

                 (liquidation amount $25 per Preferred Security)

      Aetna Capital Trust [ ], a statutory business trust created under the laws
of the State of Delaware (the "Trust"), hereby certifies that _________ (the

Trust representing undivided beneficial interests in the assets of the Trust
   77

Preferred Security) (the "Preferred Securities"). The Preferred Securities are
transferable on the books and records of the Trust, in person or by a duly
authorized attorney, upon surrender of this certificate duly endorsed and in

preferences and other terms and provisions of the Preferred Securities are set
forth in, and this certificate and the Preferred Securities represented hereby

the Amended and Restated Declaration of Trust of the Trust dated as of
___________, 199_, as the same may be amended from time to time (the
"Declaration") including the designation of the terms of Preferred Securities as
set forth in Exhibit B thereto. The Preferred Securities and the Common
Securities issued by the Trust pursuant to the Declaration represent undivided
beneficial interests in the assets of the Trust, including the Debentures (as
defined in the Declaration) issued by Aetna Services, Inc., a Connecticut
corporation ("Services"), to the Trust pursuant to the Indenture referred to in
the Declaration. The Holder is entitled to the benefits of the Guarantee

the Declaration, the Guarantee and the Indenture to the Holder without charge
upon written request to the Trust at its principal place of business or
registered office.

      The Holder of this Certificate, by accepting this Certificate, is deemed
to have (i) agreed to the terms of the Indenture and the Debentures, including
that the Debentures are subordinate and junior in right of payment to all Senior
Indebtedness (as defined in the Indenture) as and to the extent provided in the
Indenture and (ii) agreed to the terms of the Guarantee, including that the
Guarantee ranks (a) pari passu in right of payment with Aetna's and Services'
obligations under other guarantees of preferred securities, (b) subordinate and
junior in right of payment to all other liabilities of Aetna, including the
guarantee under the Indenture of the Debentures, and of Services, including the
Debentures, except those made pari passu or subordinate by their terms, and (c)
senior to all capital stock now or hereafter issued by Aetna or Services and to
any guarantee now or hereafter entered into by Aetna or Services in respect of
any of its or their capital stock.

      Upon receipt of this certificate, the Holder is bound by the Declaration
and is entitled to the benefits thereunder.

                                                                       EXHIBIT C

                                    TERMS OF

                                COMMON SECURITIES

      Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust
of Aetna Capital Trust [ ] dated as of ____________, 199__ (as amended from time
to time, the "Declaration"), the designations, rights, privileges, restrictions,
preferences and other terms and provisions of the Common Securities are set
forth below (each capitalized term used but not defined herein having the
meaning set forth in the Declaration):

      1. Designation and Number. Common Securities of the Trust with an
aggregate liquidation amount in the assets of the Trust of
__________________________________________ Dollars ($____________) and a
liquidation amount in the assets of the Trust of $25 per Common Security, are
hereby designated as "____% Common Trust Securities". The Common Security
Certificates evidencing the Common Securities shall be substantially in the form
attached hereto as Annex I, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice. The Common
Securities are to be issued and sold to Aetna Services, Inc. ("Services") in
consideration of $_____________ in cash. In connection with the issuance and
sale of the Preferred Securities and the Common Securities, the Trust will
purchase as trust assets Debentures of Services having an aggregate principal
amount equal to the aggregate liquidation amount of the Preferred Securities and
Common Securities so issued, and bearing interest at an annual rate equal to the
annual Distribution rate on the Preferred Securities and Common Securities and
having payment and redemption provisions which correspond to the payment and
redemption provisions of the Preferred Securities and Common Securities.

   
      2. Distributions. (a) Distributions payable on each Common Security will
be fixed at a rate per annum of ____% (the "Coupon Rate") of the stated
liquidation amount of $25 per Common Security. Distributions in arrears for more
than one month will bear interest at the rate per annum of ____% thereof (to the
extent permitted by applicable law), compounded [monthly]. The term
"Distributions" as used in these terms means such periodic cash distributions
and any such interest payable unless otherwise stated. A Distribution will be
made by the Property Trustee only to the extent that interest payments are made
in respect of the Debentures held by the Property Trustee. The amount of
Distributions payable for any period will be computed for any [monthly]
Distribution period on
    
   81

   
the basis of a 360-day year of twelve 30-day months[, and for any Distribution
period shorter than a 30-day month Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed].
    

   
      (b) Distributions on the Common Securities will be cumulative, will accrue
from _________, 199__ and will be payable [monthly] in arrears, on the last day
of each month commencing on __________, 199__, except as otherwise described
below, but only if and to the extent that interest payments are made in respect
of the Debentures held by the Property Trustee. So long as Services shall not be
in default in the payment of interest on the Debentures, Services has the right
under the Indenture for the Debentures to defer payments of interest by
extending the interest payment period from time to time on the Debentures for a
period not exceeding [60] consecutive [monthly] interest periods (each, an
"Extension Period") and, as a consequence, [monthly] Distributions will continue
to accrue with interest thereon (to the extent permitted by applicable law) at
the rate of ____% per annum, compounded [monthly] during any such Extension
Period. Prior to the termination of any such Extension Period, Services may
further extend such Extension Period; provided that such Extension Period
together with all such previous and further extensions thereof may not exceed
[60] consecutive [monthly] interest periods. Upon the termination of any
Extension Period and the payment of all amounts then due, Services may commence
a new Extension Period, subject to the above requirements. Payments of accrued
Distributions will be payable to Holders of Common Securities as they appear on
the books and records of the Trust on the first record date after the end of the
Extension Period.
    

      (c) Distributions on the Common Securities will be payable promptly by the
Property Trustee (or other Paying Agent) upon receipt of immediately available
funds to the Holders thereof as they appear on the books and records of the
Trust on the relevant record dates which will be one business day prior to the
relevant Distribution date unless the Preferred Securities are no longer in
book-entry only form in which event the relevant record dates will be the
fifteenth (15th) day of the month prior to the relevant Distribution date, which
record and payment dates correspond to the record and interest payment dates on
the Debentures. Distributions payable on any Common Securities that are not
punctually paid on any Distribution date as a result of Services having failed
to make the corresponding interest payment on the Debentures will forthwith
cease to be payable to the person in whose name such Common Security is
registered on the relevant record date, and such defaulted Distribution will
instead be payable to the person in whose name such Common Security is
registered on the special record date established by the Regular Trustees, which
record date shall correspond to the special record date or other specified date
determined in


                                       2
   82

accordance with the Indenture; provided, however, that Distributions shall not
be considered payable on any Distribution payment date falling within an
Extension Period unless Services has elected to make a full or partial payment
of interest accrued on the Debentures on such Distribution payment date. Subject
to any applicable laws and regulations and the provisions of the Declaration,
each payment in respect of the Common Securities will be made as described in
paragraph 9 hereof. If any date on which Distributions are payable on the Common
Securities is not a Business Day, then payment of the Distribution payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay) except that,
if such Business Day is in the next succeeding calendar year, such payment shall
be made on the immediately preceding Business Day, in each case with the same
force and effect as if made on such date.

      (d) All Distributions paid with respect to the Common Securities and the
Preferred Securities will be paid Pro Rata to the Holders thereof entitled
thereto. If an Event of Default has occurred and is continuing, the Preferred
Securities shall have a priority over the Common Securities with respect to
Distributions.

      (e) In the event that there is any money or other property held by or for
the Trust that is not accounted for under the Declaration, such money or
property shall be distributed Pro Rata among the Holders of the Preferred
Securities and Common Securities.

      3. Liquidation Distribution Upon Dissolution. In the event of any
voluntary or involuntary dissolution, winding-up or termination of the Trust,
the Holders of the Preferred Securities and Common Securities at the date of the
dissolution, winding-up or termination, as the case may be, will be entitled to
receive Pro Rata solely out of the assets of the Trust available for
distribution to Holders of Preferred Securities and Common Securities, after
satisfaction of liabilities to creditors as provided by applicable law, an
amount equal to the aggregate of the stated liquidation amount of $25 per
Preferred Security and Common Security plus accrued and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless, in connection with such dissolution, winding-up or
termination, and after satisfaction of liabilities to creditors as provided by
applicable law, Debentures in an aggregate principal amount equal to the
aggregate stated liquidation amount of such Preferred Securities and Common
Securities bearing accrued and unpaid interest in an amount equal to the accrued
and unpaid Distributions on, such Preferred Securities and Common Securities,
shall be distributed Pro Rata to the Holders of the Preferred Securities and
Common Securities in exchange for such Securities.


                                       3
   83

      If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred Securities and Common Securities shall be paid, subject
to the next paragraph, on a Pro Rata basis.

      Holders of Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution Pro Rata with Holders of Preferred
Securities, except that if an Event of Default has occurred and is continuing,
the Preferred Securities shall have a priority over the Common Securities with
respect to such Liquidation Distribution.

      4. Redemption and Distribution of Debentures. The Preferred Securities and
Common Securities may only be redeemed if Debentures having an aggregate
principal amount equal to the aggregate liquidation amount of the Preferred
Securities and Common Securities are repaid, redeemed or distributed as set
forth below:

      (a) Upon the repayment of the Debentures, in whole or in part, whether at
maturity, upon redemption at any time or from time to time on or after
__________, 200_, the proceeds of such repayment will be promptly applied to
redeem Pro Rata Preferred Securities and Common Securities having an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
repaid or redeemed, upon not less than 30 nor more than 60 days' notice, at a
redemption price of $25 per Preferred and Common Security plus an amount equal
to accrued and unpaid Distributions thereon to the date of redemption, payable
in cash (the "Redemption Price"). The date of any such repayment or redemption
of Preferred Securities and Common Securities shall be established to coincide
with the repayment or redemption date of the Debentures.

      (b) If fewer than all the outstanding Preferred Securities and Common
Securities are to be so redeemed, the Preferred Securities and the Common
Securities will be redeemed Pro Rata and the Common Securities to be redeemed
will be redeemed as described in paragraph 4(e)(ii) below. If a partial
redemption would result in the delisting of the Preferred Securities by any
national securities exchange or other organization on which the Preferred
Securities are then listed, Services pursuant to the Indenture will only redeem
Debentures in whole and, as a result, the Trust may only redeem the Common
Securities in whole.

      (c) If, at any time, a Tax Event or an Investment Company Event (each as
hereinafter defined, and each a "Special Event") shall occur and be continuing,
the Regular Trustees shall, unless the Debentures are redeemed in the limited
circumstances described below, dissolve the Trust and, after satisfaction of


                                       4
   84

creditors, cause Debentures held by the Property Trustee having an aggregate
principal amount equal to the aggregate stated liquidation amount of and accrued
and unpaid interest equal to accrued and unpaid Distributions on, and having the
same record date for payment as the Preferred Securities and Common Securities,
to be distributed to the Holders of the Preferred Securities and Common
Securities on a Pro Rata basis in liquidation of such Holders' interests in the
Trust, within 90 days following the occurrence of such Special Event (the "90
Day Period"); provided, however, that in the case of the occurrence of a Tax
Event, as a condition of such dissolution and distribution, the Regular Trustees
shall have received an opinion of a nationally recognized independent tax
counsel experienced in such matters (a "No Recognition Opinion"), which opinion
may rely on any then applicable published revenue rulings of the Internal
Revenue Service, to the effect that the Holders of the Preferred Securities will
not recognize any gain or loss for United States federal income tax purposes as
a result of the dissolution of the Trust and distribution of Debentures; and
provided, further, that, if and as long as at the time there is available to the
Trust the opportunity to eliminate, within such 90 Day Period, the Special Event
by taking some ministerial action, such as filing a form or making an election,
or pursuing some other similar reasonable measure that has no adverse effect on
the Trust, Services, Aetna or the Holders of the Preferred Securities
("Ministerial Action") the Trust will pursue such measure in lieu of
dissolution.

      If in the case of the occurrence of a Tax Event, (i) the Regular Trustees
have received an opinion (a "Redemption Tax Opinion") of nationally recognized
independent tax counsel experienced in such matters that, as a result of a Tax
Event, there is more than an insubstantial risk that Services would be precluded
from deducting the interest on the Debentures for United States federal income
tax purposes even if the Debentures were distributed to the Holders of Preferred
Securities and Common Securities in liquidation of such Holder's interest in the
Trust as described in this paragraph 4(c) or (ii) the Regular Trustees shall
have been informed by such tax counsel that a No Recognition Opinion cannot be
delivered to the Trust, Services shall have the right at any time, upon not less
than 30 nor more than 60 days' notice, to redeem the Debentures in whole or in
part for cash at the Redemption Price within 90 days following the occurrence of
such Tax Event, and promptly following such redemption Preferred Securities and
Common Securities with an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so redeemed will be redeemed by the Trust at
the Redemption Price on a Pro Rata basis: provided, however, that, if at the
time there is available to Services or the Regular Trustees on behalf of the
Trust the opportunity to eliminate, within such 90 day period, the Tax Event by
taking some Ministerial Action, Services or the Holders of the Preferred
Securities, Services or the Regular Trustees on behalf of the Trust will pursue
such measure in lieu of redemption; and provided, further, that Services shall


                                       5
   85

have no right to redeem the Debentures while the Regular Trustees on behalf of
the Trust are pursuing such Ministerial Action. The Common Securities will be
redeemed Pro Rata with the Preferred Securities, except that if an Event of
Default under the Indenture has occurred and is continuing, the Preferred
Securities will have a priority over the Common Securities with respect to
payment of the Redemption Price.

      "Tax Event" means that the Regular Trustees shall have obtained an opinion
of nationally recognized independent tax counsel experienced in such matters (a
"Dissolution Tax Opinion") to the effect that on or after __________, 199_ as a
result of (a) any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein, (b) any amendment
to, or change in, an interpretation or application of any such laws or
regulations by any legislative body, court, governmental agency or regulatory
authority (including the enactment of any legislation and the publication of any
judicial decision or regulatory determination), (c) any interpretation or
pronouncement that provides for a position with respect to such laws or
regulations that differs from the theretofore generally accepted position or (d)
any action taken by any governmental agency or regulatory authority, which
amendment or change is enacted, promulgated, issued or announced or which
interpretation or pronouncement is issued or announced or which action is taken,
in each case on or after __________, 199_, there is more than an insubstantial
risk that (i) the Trust is, or will be within 90 days of the date thereof,
subject to United States federal income tax with respect to income accrued or
received on the Debentures, (ii) the Trust is, or will be within 90 days of the
date thereof, subject to more than a de minimis amount of taxes, duties or other
governmental charges or (iii) interest payable by Services to the Trust on the
Debentures is not, or within 90 days of the date thereof will not be, deductible
by Services for United States federal income tax purposes.

      "Investment Company Event" means that the Regular Trustees shall have
received an opinion of nationally recognized independent counsel experienced in
practice under the Investment Company Act that, as a result of the occurrence of
a change in law or regulation or a change in interpretation or application of
law or regulation by any legislative body, court, governmental agency or
regulatory authority (a "Change in 1940 Act Law"), there is more than an
insubstantial risk that the Trust is or will be considered an Investment Company
which is required to be registered under the Investment Company Act, which
Change in 1940 Act Law becomes effective on or after __________, 199_.

      On the date fixed for any distribution of Debentures, upon dissolution of
the Trust, (i) the Common Securities will no longer be deemed to be outstanding


                                       6
   86

and (ii) any certificates representing Common Securities will be deemed to
represent beneficial interests in the Debentures having an aggregate principal
amount equal to the stated liquidation amount of, and bearing accrued and unpaid
interest equal to accrued and unpaid Distributions on, such Common Securities
until such certificates are presented to Aetna or its agent for transfer or
reissuance.

   
      (d) The Trust may not redeem fewer than all the outstanding Common
Securities unless all accrued and unpaid Distributions have been paid on all
Common Securities for all [monthly] Distribution periods terminating on or prior
to the date of redemption.
    

      (e)(i) Notice of any redemption of, or notice of distribution of
Debentures in exchange for, the Preferred Securities and Common Securities (a
"Redemption/Distribution Notice") will be given by the Regular Trustees on
behalf of the Trust by mail to each Holder of Preferred Securities and Common
Securities to be redeemed or exchanged not less than 30 nor more than 60 days
prior to the date fixed for redemption or exchange thereof. For purposes of the
calculation of the date of redemption or exchange and the dates on which notices
are given pursuant to this paragraph (e)(i), a Redemption/Distribution Notice
shall be deemed to be given on the day such notice is first mailed by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities. Each Redemption/Distribution Notice shall be addressed to the
Holders of Preferred Securities and Common Securities at the address of each
such Holder appearing in the books and records of the Trust. No defect in the
Redemption/Distribution Notice or in the mailing of either thereof with respect
to any Holder shall affect the validity of the redemption or exchange
proceedings with respect to any other Holder.

      (ii) In the event that fewer than all the outstanding Common Securities
are to be redeemed, the Common Securities to be redeemed will be redeemed Pro
Rata from each Holder of Common Securities (subject to adjustment to eliminate
fractional Common Securities).

      (iii) If the Trust gives a Redemption/ Distribution Notice in respect of a
redemption of Common Securities as provided in this paragraph 4 (which notice
will be irrevocable) then immediately prior to the close of business on the
redemption date, provided that Services has paid to the Property Trustee in
immediately available funds a sufficient amount of cash in connection with the
related redemption or maturity of the Debentures, Distributions will cease to
accrue on the Common Securities called for redemption, such Common Securities
will no longer be deemed to be outstanding and all rights of Holders of such
Common Securities so called for redemption will cease, except the right of the
Holders of such Common Securities to receive the Redemption Price, but without


                                       7
   87

interest on such Redemption Price. Neither the Trustees nor the Trust shall be
required to register or cause to be registered the transfer of any Common
Securities which have been so called for redemption. If any date fixed for
redemption of Common Securities is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) except that, if such Business Day falls in the next calendar
year, such payment will be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date fixed for
redemption. If payment of the Redemption Price in respect of Common Securities
is improperly withheld or refused and not paid by the Property Trustee,
Distributions on such Common Securities will continue to accrue, from the
original redemption date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the Redemption Price.

      (iv) Redemption/Distribution Notices shall be sent by the Regular Trustees
on behalf of the Trust to the Holders of the Common Securities.

      (v) Upon the date of dissolution of the Trust and distribution of
Debentures as a result of the occurrence of a Special Event, Common Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so distributed, and the Common Securities will no longer be deemed outstanding
and may be canceled by the Regular Trustees. The Debentures so distributed shall
have an aggregate principal amount equal to the aggregate liquidation amount of
the Common Securities so distributed.

      5. Voting Rights. (a) Except as provided under paragraph 5(b) below and as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

      (b) Holders of Common Securities have the sole right under the Declaration
to increase or decrease the number of Trustees, and to appoint, remove or
replace a Trustee, any such increase, decrease, appointment, removal or
replacement to be approved by Holders of Common Securities representing a
Majority in liquidation amount of the Common Securities.

      If any proposed amendment to the Declaration provides for, or the Regular
Trustees otherwise propose to effect, (i) any action that would adversely affect
the powers, preferences or special rights of the Securities, whether by way of
amendment to the Declaration or otherwise, or (ii) the dissolution, winding-up
or termination of the Trust, other than in connection with the distribution of
Debentures held by the Property Trustee, upon the occurrence of a Special Event
or in connection with the redemption of Common Securities as a consequence of a


                                       8
   88

redemption of Debentures, then the Holders of outstanding Securities will be
entitled to vote on such amendment or proposal as a class and such amendment or
proposal shall not be effective except with the approval of the Holders of
Securities representing 66-2/3% in liquidation amount of such Securities;
provided, however, that (A) if any amendment or proposal referred to in clause
(i) above would adversely affect only the Preferred Securities or the Common
Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of 66-2/3% in liquidation amount of such class of
Securities, (B) the rights of Holders of Common Securities under Article V of
the Declaration to increase or decrease the number of, and to appoint, replace
or remove, Trustees shall not be amended without the consent of each Holder of
Common Securities, and (C) amendments to the Declaration shall be subject to
such further requirements as are set forth in Sections 12.1 and 12.2 of the
Declaration.

      In the event the consent of the Property Trustee as the holder of the
Debentures, is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the Property
Trustee shall request the written direction of the Holders of the Securities
with respect to such amendment, modification or termination. The Property
Trustee shall vote with respect to such amendment, modification or termination
as directed by a Majority in liquidation amount of the Securities voting
together as a single class; provided that where such amendment, modification or
termination of the Indenture requires the consent or vote of (1) holders of
Debentures representing a specified percentage greater than a majority in
principal amount of the Debentures or (2) each holder of Debentures, the
Property Trustee may only vote with respect to that amendment, modification or
termination as directed by, in the case of clause (1) above, the vote of Holders
of Securities representing such specified percentage of the aggregate
liquidation amount of the Securities, or, in the case of clause (2) above, each
Holder of Securities; and provided, further, that the Property Trustee shall be
under no obligation to take any action in accordance with the directions of the
Holders of the Securities unless the Property Trustee shall have received, at
the expense of the Sponsor, an opinion of nationally recognized independent tax
counsel recognized as an expert in such matters to the effect that the Trust
will not be classified for United States federal income tax purposes as an
association taxable as a corporation or a partnership on account of such action
and will be treated as a grantor trust for United States federal income tax
purposes following such action.

      Subject to Section 2.6 of the Declaration, and the provisions of this and
the next succeeding paragraph, the Holders of a Majority in liquidation amount
of the Common Securities, voting separately as a class shall have the right to
(A) on behalf of all Holders of Common Securities, waive any past default that
is


                                       9
   89

waivable under the Declaration (subject to, and in accordance with the
Declaration) and (B) direct the time, method, and place of conducting any
proceeding for any remedy available to the Property Trustee, or exercising any
trust or power conferred upon the Property Trustee under the Declaration,
including the right to direct the Property Trustee, as holder of the Debentures,
to (i) direct the time, method and place of conducting any proceeding for any
remedy available to the Debenture Trustee, or exercising any trust or power
conferred on the Debenture Trustee with respect to the Debentures, (ii) waive
any past default and its consequences that is waivable under Section 6.06 of the
Indenture, or (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable; provided that
where the taking of any action under the Indenture requires the consent or vote
of (1) holders of Debentures representing a specified percentage greater than a
majority in principal amount of the Debentures or (e) each holder of Debentures,
the Property Trustee may only take such action if directed by, in the case of
clause (1) above, the vote of Holders of Common Securities representing such
specified percentage of the aggregate liquidation amount of the Common
Securities, or, in the case of clause (2) above, each Holder of Common
Securities. Pursuant to this paragraph, the Property Trustee shall not revoke,
or take any action inconsistent with, any action previously authorized or
approved by a vote of the Holders of the Preferred Securities, and shall not
take any action in accordance with the direction of the Holders of the Common
Securities under this paragraph if the action is prejudicial to the Holders of
Preferred Securities. Other than with respect to directing the time, method and
place of conducting any proceeding for any remedy available to the Property
Trustee or the Debenture Trustee as set forth above, the Property Trustee shall
be under no obligation to take any of the foregoing actions at the direction of
the Holders of Common Securities unless the Properties Trustee shall have
received, at the expense of the Sponsor, an opinion of nationally recognized
independent tax counsel recognized as expert in such matters to the effect that
the Trust will not be classified for United States federal income tax purposes
as an association taxable as a corporation or a partnership on account of such
action and will be treated as a grantor trust for United States income tax
purposes following such action.

      Notwithstanding any other provision of these terms, each Holder of Common
Securities will be deemed to have waived any Event of Default with respect to
the Common Securities and its consequences until all Events of Default with
respect to the Preferred Securities have been cured, waived by the Holders of
Preferred Securities as provided in the Declaration or otherwise eliminated, and
until all Events of Default with respect to the Preferred Securities have been
so cured, waived by the Holders of Preferred Securities or otherwise eliminated,
the Property Trustee will be deemed to be acting solely on behalf of the Holders
of Preferred Securities and only the Holders of the Preferred Securities will
have the


                                       10
   90

right to direct the Property Trustee in accordance with the terms of the
Declaration or of the Securities. In the event that any Event of Default with
respect to the Preferred Securities is waived by the Holders of Preferred
Securities as provided in the Declaration, the Holders of Common Securities
agree that such waiver shall also constitute the waiver of such Event of Default
with respect to the Common Securities for all purposes under the Declaration
without any further act, vote or consent of the Holders of the Common
Securities.

      A waiver of an Indenture Event of Default by the Property Trustee at the
direction of the Holders of the Preferred Securities will constitute a waiver of
the corresponding Event of Default under the Declaration in respect of the
Securities.

      Any required approval of Holders of Common Securities may be given at a
separate meeting of Holders of Common Securities convened for such purpose, at a
meeting of all of the Holders of Securities of the Trust or pursuant to written
consent. The Regular Trustees will cause a notice of any meeting at which
Holders of Common Securities are entitled to vote, or of any matter upon which
action by written consent of such Holders is to be taken, to be mailed to each
Holder of record of Common Securities. Each such notice will include a statement
setting forth (i) the date of such meeting or the date by which such action is
to be taken, (ii) a description of any resolution proposed for adoption at such
meeting on which such Holders are entitled to vote or of such matter upon which
written consent is sought and (iii) instructions for the delivery of proxies or
consents.

      No vote or consent of the Holders of Common Securities will be required
for the Trust to redeem and cancel Common Securities in accordance with the
Declaration.

      6. Pro Rata Treatment. A reference in these terms of the Common Securities
to any payment, distribution or treatment as being "Pro Rata" shall mean pro
rata to each Holder of Securities according to the aggregate liquidation amount
of the Securities held by the relevant Holder in relation to the aggregate
liquidation amount of all Securities outstanding unless, in relation to a
payment, an Event of Default has occurred and is continuing, in which case any
funds available to make such payment shall be paid first to each Holder of the
Preferred Securities pro rata according to the aggregate liquidation amount of
Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate liquidation
amount of Common Securities held by the relevant Holder relative to the
aggregate liquidation amount of all Common Securities outstanding.


                                       11
   91

      7. Ranking. The Common Securities rank pari passu and payment thereon will
be made Pro Rata with the Preferred Securities except that where an Event of
Default occurs and is continuing, the rights of Holders of Common Securities to
payment in respect of Distributions and payments upon liquidation, redemption or
otherwise are subordinate to the rights of Holders of the Preferred Securities.

      8. Mergers, Consolidations or Amalgamations. The Trust may not
consolidate, amalgamate, merge with or into, or be replaced by, or convey,
transfer or lease its properties and assets to, any corporation or other body.

      9. Transfers, Exchanges, Method of Payments. Payment of Distributions and
payments on redemption of the Common Securities will be payable, the transfer of
the Common Securities will be registrable, and Common Securities will be
exchangeable for Common Securities of other denominations of a like aggregate
liquidation amount, at the principal corporate trust office of the Property
Trustee in The City of Chicago; provided that payment of Distributions may be
made at the option of the Regular Trustees on behalf of the Trust by check
mailed to the address of the persons entitled thereto and that the payment on
redemption of any Common Security will be made only upon surrender of such
Common Security to the Property Trustee. Notwithstanding the foregoing,
transfers of Common Securities are subject to conditions set forth in Section
9.1(c) of the Declaration.

      10. Acceptance of Indenture. Each Holder of Common Securities, by the
acceptance thereof, agrees to the provisions of the Indenture and the
Debentures, including the subordination provisions thereof.

      11. No Preemptive Rights. The Holders of Common Securities shall have no
preemptive rights to subscribe to any additional Common Securities or Preferred
Securities.

      12. Miscellaneous. These terms shall constitute a part of the Declaration.
The Trust will provide a copy of the Declaration and the Indenture to a Holder
without charge on written request to the Trust at its principal place of
business.
