         of the Holders of all of the Trust Preferred Securities, waive any past
         Event of Default in respect of the Trust Preferred Securities and its
         consequences, provided that, if the corresponding Debenture Event of
         Default or Other Document Event of Default:

                  (i) is not waivable under the Debentures or any Other
                  Document, if any, as the case may be, the Event of Default
                  under this Agreement shall also not be waivable; or

                  (ii) requires the consent or vote of greater than a majority
                  in principal amount of the holders of the Debentures or more
                  than a majority of other interests in such Other Document, as
                  the case may be (a "Super Majority"), to be waived under the
                  Indenture or such Other Document, as the case may be, the
                  Event of Default under this Agreement may only be waived by
                  the vote of the relevant Super Majority in liquidation amount
                  of Holders of the Trust Preferred Securities.

                  The foregoing provisions of this Section 2.6(a) shall be in
         lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such
         Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly
         excluded from this Agreement and the Trust Securities, as permitted by
         the Trust Indenture Act. Upon such waiver, any such Debenture Event of
         Default or Other Document Event of Default shall cease to exist, and
         any Event of Default with respect to the Trust Preferred Securities
         arising therefrom shall be deemed to have been cured, for every purpose
         of this Agreement, but no such waiver shall extend to any subsequent or
         other default or Event of Default with respect to the Trust Preferred
         Securities or impair any right consequent thereon. Any waiver by the
         Holders of the Trust Preferred Securities of an Event of Default with
         respect to the Trust Preferred Securities shall also be deemed to
         constitute a waiver by the Holders of the Common Securities of

                                       10
<PAGE>

         the Holders of the Common Securities.

                  The Holders of a Majority in liquidation amount of the Trust
         Preferred Securities shall have the right to direct the time, method
         and place of conducting any proceeding for any remedy available to the
         Property Trustee or to direct the exercise of any trust or power
         conferred upon the Property Trustee, including the right to direct the
         Property Trustee to exercise the remedies available to it as a holder
         of the Debentures and any Other Documents; provided, however, that
         (subject to the provisions of Section 3.9) the Property Trustee shall
         have the right to decline to follow any such direction if the Property
         Trustee shall determine that the action so directed would be unjustly
         prejudicial to the Holders not taking part in such direction or if the
         Property Trustee, being advised by competent legal counsel, determines
         that the action or proceeding so directed may not lawfully be taken or
         if the Property Trustee, in good faith, by its board of directors or
         trustees, executive committee, or a trust committee of directors or
         trustees, and/or Responsible Officers, shall determine that the action
         or proceeding so directed would involve the Property Trustee in
         personal liability.

         (b) The Holders of a Majority in liquidation amount of the Common
         Securities may, by vote or consent, on behalf of the Holders of all of
         the Common Securities, waive any past Event of Default with respect to
         the Common Securities and its consequences, provided that, if the
         underlying Event of Default under the Indenture:

                  (i) is not waivable under the Debentures or Other Document,
                  except where the Holders of the Common Securities are deemed
                  to have waived such Event of Default under this Agreement as
                  provided elsewhere in this Section 2.6, the Event of Default
                  under this Agreement shall also not be waivable; or

                  (ii) requires the consent or vote of a Super Majority to be
                  waived, except where the Holders of the Common Securities are
                  deemed to have waived such Event of Default under this
                  Agreement as provided below in this Section 2.6, such Event of
                  Default under this Agreement may only be waived by the vote or
                  consent of the Holders of at least the proportion in aggregate
                  liquidation amount of the Common Securities that the relevant
                  Super Majority represents of the aggregate principal amount of
                  the Debentures outstanding;

         provided further, that, notwithstanding (i) or (ii) above, each Holder
         of the Common Securities shall be deemed to have waived any such Event
         of Default and all Events of Default with respect to the Common
         Securities and its consequences if all Events of Default with respect
         to the Trust Preferred Securities have been cured, waived or otherwise
         eliminated, and until such Events of Default 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 Trust Preferred
         Securities and only the Holders of the Trust Preferred Securities will
         have the right to direct the Property Trustee in accordance with the
         terms of this Agreement and the Securities. The foregoing provisions of
         this Section 2.6(b) shall be in lieu of Sections 316(a)(1)(A) and 316
         (a)(1)(B) and of the Trust

         and the Securities, as permitted by the Trust Indenture Act. Subject to
         the foregoing provisions of this Section 2.6(b), upon such waiver, any
         such Debenture Event of Default or Other Document Event of 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 Agreement, 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.

         (c) A waiver of a Debenture Event of Default or Other Document Event of
         Default by the Property Trustee at the direction of the Holders of the
         Trust Preferred Securities constitutes a waiver of the corresponding
         Event of Default with respect to the Trust Preferred Securities under
         this Agreement. Any waiver of a Debenture Event of Default or Other
         Document Event of Default by the Property Trustee at the direction of
         the Holders of the Trust Preferred Securities shall also be deemed to
         constitute a waiver by the Holders of the Common Securities of the
         corresponding Event of Default under this Agreement with respect to the
         Common Securities for all purposes of this Agreement without further
         act, vote or consent of the Holders of the Common Securities. The
         foregoing provisions of this Section 2.6(c) shall be in lieu of Section
         316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B)
         of the Trust Indenture Act is hereby expressly excluded from this

         after the respective payment dates therefore, or to institute suit for
         the enforcement of any such payment on or after such payment dates,
         shall not be impaired without the consent of each such Holder.

         Officer of the Property Trustee obtains actual knowledge of the
         occurrence of a default, transmit by mail, first class postage prepaid,

         of this Section 2.7(a) being hereby defined to include Debenture Events
         of Default and Other Document Events of Default, if any, not including
         any periods of grace provided for therein and irrespective of the

         accordance with the terms of, any Debenture or Other Document or the
         Securities, the Property Trustee shall be protected in withholding such

         interests of the Holders of the Securities.

         (b) The Property Trustee shall not be deemed to have knowledge of any
         default except:

                  or otherwise in accordance with the terms of the Debentures or
                  Other Documents or the Securities; and

                  (iii) any default as to which the Property Trustee shall have
                  received written notice or of which a Responsible Officer of
                  the Property Trustee shall have actual knowledge.

         (c) The Sponsor and the Administrative Trustee shall file annually
         within 30 days after May 15 of each year, commencing with the May 15

                                  ORGANIZATION

Section 3.1 Name. The Trust is named "Apache Trust [I/II]," as such name may be
modified from time to time in accordance with the Statutory Trust Act. The
Administrative Trustees shall give prompt written notice of any change in the
name of the Trust to the Delaware Trustee, the Property Trustee and the Holders
of the Securities. The Trust's activities may be conducted under the name of the
Trust or any other name deemed advisable by the Administrative Trustees.

Section 3.2 Office. The address of the principal office of the Trust is c/o
Apache Corporation, One Post Oak Central, 2000 Post Oak Boulevard, Suite 100,
Houston, Texas 77056-4400. On ten Business Days prior written notice to the
Property Trustee and Holders of the Securities, the Administrative Trustees may
designate another principal office.

Section 3.3 Purposes. The exclusive purposes and functions of the Trust are and
the Trust shall have the power and authority (a) to issue and sell the
Securities and use the gross proceeds from such sale to acquire the Debentures
and any Other Documents specified in the Terms and Conditions, (b) to enter into
or hold each Other Document, if any, to be entered into or held by the Trust in
accordance with the Terms and Conditions and (c) to engage in only those other
activities necessary or incidental thereto. The Trust shall not borrow money,
issue debt or reinvest proceeds derived from investments, pledge any of its
assets, execute mortgages or otherwise undertake (or permit to be undertaken)
any activity that would cause the Trust not to be classified for U.S. federal
income tax purposes as a grantor trust. It is the intent of the parties to this
Agreement for the Trust to be classified as a grantor trust for U.S. federal
income tax purposes under Subpart E of Subchapter J of the Code, pursuant to
which the owners of the Trust Preferred Securities and the Common Securities
will be the owners of the Trust for U.S. federal income tax purposes, and such
owners will include directly in their gross income the income, gain, deduction
or loss of the Trust as if the Trust did not exist. By the acceptance of this
Agreement neither the Trustees nor the Sponsor or the Holders of the Trust
Preferred Securities or Common Securities will take any position for U.S.
Federal income tax purposes, or permit the Trust to make any election, which is
contrary to the classification of the Trust as a grantor trust.

                           Document, as the case may be, would require the

         regard to the Trust Property have been executed and delivered.

         (b) The Property Trustee shall not transfer its right, title and

                  Securities. The Property Trustee Account shall be one or more
                  accounts maintained with one or more banking institutions

         terms of the Securities and this Agreement.

         (e) Subject to Section 3.9(a), the Property Trustee shall take any
         Legal Action which arises out of or in connection with an Event of
         Default of which a Responsible Officer of the Property Trustee has
         actual knowledge or the Property Trustee's duties and obligations under
         this Agreement, the Statutory Trust Act or the Trust Indenture Act;
         provided, however, that if the Property Trustee fails to enforce its
         rights under this Agreement and the Debentures or any Other Document
         after a Holder of Trust Preferred Securities has made a written
         request, such Holder of Trust Preferred Securities may, to the fullest
         extent permitted by applicable law and subject to the terms of this
         Agreement and the Indenture, institute a legal proceeding against the
         Debenture Issuer[, the Debenture Guarantor] or any obligor under any
         Other Document, as the case may be, without first instituting any legal
         proceeding against the Property Trustee or any other Person.
         Notwithstanding the foregoing, if an Event of Default has occurred and
         is continuing and such event is attributable to (i) the failure of the
         Debenture Issuer [or the Debenture Guarantor, as the case may be,] to
         pay interest or any premium on or principal of the Debentures on the
         date such interest or principal is otherwise payable (including, in the
         case of repayment or redemption, on the repayment or redemption date)
         and, if applicable, not during an authorized Extension Period (as
         defined in the Terms and Conditions) or, if the Debentures are
         exchangeable or convertible, the failure of the Debenture Issuer to
         convert or exchange the Debentures into or for other property in
         accordance with the terms thereof, or (ii) the failure of any obligor
         under any Other Document to pay or deliver cash, securities or other
         property in accordance with the terms of such Other Document, then, in
         the case of (i) and (ii), a Holder of Trust Preferred Securities may
         directly institute a proceeding (a "Direct Action") for enforcement of
         payment or delivery to such Holder of the principal of or interest on
         or other property deliverable upon the exchange or conversion of
         Debentures having a

                                       19
<PAGE>

         principal amount equal to the aggregate liquidation amount of the Trust
         Preferred Securities of such holder on or after the due date specified
         in the Debentures or any cash, securities or other property that is
         required to be paid or delivered pursuant to such Other Document on or
         after the due date therefor equal to the percentage of outstanding
         securities represented by such Holder's Securities. In connection with
         such Direct Action, the rights of the Holders of Common Securities will
         be subordinated to the rights of such Holders of Trust Preferred
         Securities. Except as provided in the preceding sentences, the Holders
         of Trust Preferred Securities will not be able to exercise directly any
         other remedy available to the holders of the Debentures or Other
         Documents.

         (f) The Property Trustee shall continue to serve as a Trustee until
         either:

                  (i) the Trust has been completely dissolved and wound up and
                  the proceeds of the liquidation distributed to the Holders of
                  Securities and the Trust is terminated, in accordance with the
                  terms of the Securities and this Agreement; or

                  (ii) a successor Property Trustee has been appointed and has
                  accepted that appointment in accordance with Section 5.6 (a
                  "Successor Property Trustee").

         (g) The Property Trustee shall have the legal power to exercise all of
         the rights, powers and privileges of the Trust as holder of Debentures
         under the Indenture and as beneficiary of or party to any Other
         Document and, if an Event of Default actually known to a Responsible
         Officer of the Property Trustee occurs and is continuing, the Property
         Trustee shall, for the benefit of Holders of the Securities, enforce
         the rights of the Trust as holder of the Debentures and as beneficiary
         of or party to any Other Document subject, in each case, to the rights
         of the Holders pursuant to the terms of the Securities and this
         Agreement.

         (h) The Property Trustee shall be authorized to undertake any actions
         set forth in Section 317(a) of the Trust Indenture Act.

         (i) Subject to this Section 3.8, the Property Trustee shall have none
         of the duties, liabilities, powers or the authority of the
         Administrative Trustees set forth in Section 3.6.

         (j) For such time as the Property Trustee is the Paying Agent, the
         Property Trustee may authorize one or more Persons to act as additional
         Paying Agents and to make distributions, redemption payments or
         liquidation payments on behalf of the Trust with respect to all
         Securities. Any such additional Paying Agent may be removed by the
         Property Trustee, at any time, so long as the Property Trustee remains
         as Paying Agent and a successor Paying Agent or additional Paying
         Agents may be (but are not required to be) appointed at any time by the
         Property Trustee.

         (k) The Property Trustee must exercise the powers set forth in this
         Section 3.8 in a manner that is consistent with the purposes and
         functions of the Trust set out in Section 3.3, and the Property Trustee
         shall not take any action that is inconsistent with the purposes and
         functions of the Trust set out in Section 3.3.

Section 3.9 Certain Duties and Responsibilities of the Property Trustee.

         (a) The Property Trustee, before the occurrence of any Event of Default
         and after the curing or waiver of all Events of Default that may have
         occurred, shall undertake to perform only such duties as are
         specifically set forth in this Agreement and no implied covenants shall
         be read into this Agreement against the Property Trustee. In case an
         Event of Default has occurred (that has not been cured or waived
         pursuant to Section 2.6) of which a Responsible Officer of the Property
         Trustee has actual knowledge, the Property Trustee shall exercise such
         of the rights and powers vested in it by this Agreement, and use the
         same degree of care and skill in their exercise, as a prudent person
         would exercise or use under the circumstances in the conduct of his or
         her own affairs.

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

                  (i) prior to the occurrence of an Event of Default and after
                  the 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 Agreement and the Property Trustee
                           shall not be liable except for the performance of
                           such duties and obligations as are specifically set
                           forth in this Agreement, and no implied covenants or
                           obligations shall be read into this Agreement 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 Agreement; provided, that 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 Agreement;

                  (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 of not less than
                  a Majority in liquidation amount of the Securities relating to
                  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
                  this Agreement;

                                       21
<PAGE>

                  (iv) no provision of this Agreement 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 grounds for believing that the
                  repayment of such funds or liability is not reasonably assured
                  to it under the terms of this Agreement or if indemnity
                  reasonably satisfactory to the Property Trustee against such
                  risk or liability is not reasonably assured to it;

                  (v) the Property Trustee's sole duty with respect to the
                  custody, safe keeping and physical preservation of the Trust
                  Property and the Property Trustee Account shall be to deal
                  with such property in a manner that is similar to the manner
                  in which the Property Trustee deals with similar property for
                  its fiduciary accounts generally, subject to the protections
                  and limitations on liability afforded to the Property Trustee
                  under this Agreement, the Statutory Trust Act and the Trust
                  Indenture Act;

                  (vi) the Property Trustee shall have no duty or liability for
                  or with respect to the value, genuineness, existence or
                  sufficiency of the Trust Property or the payment of any taxes
                  or assessments levied thereon or in connection therewith;

                  (vii) the Property Trustee shall not be liable for any
                  interest on any money received by it except as it may
                  otherwise agree in writing with the Sponsor; money held by the
                  Property Trustee need not be segregated from other funds held
                  by it except in relation to the Property Trustee Account
                  maintained by the Property Trustee pursuant to Section
                  3.8(c)(i) and except to the extent otherwise required by law;
                  and

                  (viii) the Property Trustee shall not be responsible for
                  monitoring the compliance by the Administrative Trustees or
                  the Sponsor with their respective duties under this Agreement,
                  nor shall the Property Trustee be liable for any default or
                  misconduct of the Administrative Trustees or the Sponsor.

Section 3.10 Certain Rights of Property Trustee.

         (a) Subject to the provisions of Section 3.9:

                  (i) the Property Trustee may conclusively rely and shall be
                  fully protected in acting or refraining from acting upon any
                  resolution, certificate, statement, instrument, opinion,
                  report, notice, request, direction, consent, order, bond,
                  debenture, note, other evidence of indebtedness or other paper
                  or document believed by it to be genuine and to have been
                  signed, sent or presented by the proper party or parties;

                  (ii) any direction or act of the Sponsor or the Administrative
                  Trustees contemplated by this Agreement shall be sufficiently
                  evidenced by a Direction or an Officers' Certificate;

                                       22
<PAGE>

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

                  (iv) the Property Trustee shall have no duty to see to any
                  recording, filing or registration of any instrument (including
                  any financing or continuation statement or any filing under
                  tax or securities laws) or any rerecording, refiling or
                  registration thereof;

                  (v) the Property Trustee may consult with competent legal
                  counsel or other competent experts and the advice or written
                  opinion of such counsel and experts with respect to legal
                  matters or advice within the scope of such legal counsel's or
                  experts' area of expertise shall be full and complete
                  authorization and protection in respect of any action taken,
                  suffered or omitted by it hereunder in good faith and in
                  accordance with such advice or opinion. Such counsel may be
                  counsel to the Sponsor or any of its Affiliates, and may
                  include any of its employees; and the Property Trustee shall
                  have the right at any time to seek instructions concerning the
                  administration of this Agreement from any court of competent
                  jurisdiction;

                  (vi) the Property Trustee shall be under no obligation to
                  exercise any of the rights or powers vested in it by this
                  Agreement at the request or direction of any Holder, unless
                  (A) such Holder shall have provided to the Property Trustee
                  security and indemnity, reasonably satisfactory to the
                  Property Trustee, against the reasonable costs, expenses
                  (including reasonable attorneys' fees and expenses and the
                  reasonable expenses of the Property Trustee's agents, nominees
                  or custodians) and liabilities that might be incurred by it in
                  complying with such request or direction, including such
                  reasonable advances as may be requested by the Property
                  Trustee and (B) the Property Trustee has obtained the legal
                  opinions, if any, required by the applicable provisions of
                  this Agreement, provided that nothing contained in this
                  Section 3.10(a)(vi) shall be taken to relieve the Property
                  Trustee, upon the occurrence of an Event of Default, of its
                  obligation to exercise the rights and powers vested in it by
                  this Agreement;

                  (vii) the Property Trustee shall be under no obligation to
                  conduct an investigation into the facts or matters stated in
                  any resolution, certificate, statement, instrument, opinion,
                  report, notice, request, direction, consent, order, bond,
                  debenture, note, other evidence of indebtedness or other paper
                  or document, but the Property Trustee, in its discretion, may
                  make such further inquiry or investigation into such facts or
                  matters as it may see fit;

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

                                       23
<PAGE>

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

                  (ix) any action taken by the Property Trustee or its agents
                  hereunder shall bind the Trust and 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 to the authority of the Property Trustee to so act or as to
                  its compliance with any of the terms and provisions of this
                  Agreement, both of which shall be conclusively evidenced by
                  the Property Trustee's or its agent's taking such action;

                  (x) whenever in the administration of this Agreement the
                  Property Trustee shall deem it desirable to receive
                  instructions with respect to enforcing any remedy or right or
                  taking any other action hereunder, the Property Trustee

                           (A) may request instructions from the Holders (which
                           instructions may only be given by the Holders of the
                           same proportion in liquidation amount of the
                           Securities as would be entitled to direct the
                           Property Trustee under the terms of the Securities in
                           respect of such remedy, right or action)

                           (B) may refrain from enforcing such remedy or right
                           or taking such other action until such instructions
                           are received, and

                           (C) shall be protected in conclusively relying on or
                           acting in accordance with such instructions, provided
                           that the Property Trustee shall not take any action
                           unless it shall have obtained the legal opinions
                           required by the applicable provisions of this
                           Agreement;

                  (xi) except as otherwise expressly provided by this Agreement,
                  the Property Trustee shall not be under any obligation to take
                  any action that is discretionary under the provisions of this
                  Agreement; and

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

         (b) No provision of this Agreement shall be deemed to impose any duty
         or obligation on the Property Trustee to perform any act or acts or

                  by any nationally recognized statistical rating organization;

                  (v) such merger, conversion, consolidation, amalgamation or

                  Successor Securities and any Successor Trust Preferred Common
                  Securities) in any material respect;

                  Securities at least to the extent provided by the Securities
                  Guarantees; and

         amalgamate or merge with or into, or replace it if such consolidation,

         or Successor Entity to be classified as other than a grantor trust for
         U.S. Federal income tax purposes.

                           Securities; or

                           (B) until the assets of the Trust have been
                           completely liquidated and the proceeds thereof
                           distributed to the Holders of the Securities and the
                           Trust is terminated pursuant to the terms of this
                           Agreement and the Securities; and

                  (ii) no such resignation of the Delaware Trustee shall be
                  effective until a Successor Delaware Trustee has been
                  appointed and has accepted such appointment by instrument

                  the Trust, the Sponsor, the Property Trustee, the resigning
                  Delaware Trustee and, after an Event of Default has occurred
                  and is continuing, the Holders of Trust Preferred Securities.

         (d) The Holders of the Common Securities or, if an Event of Default has
         occurred and is continuing after the issuance of any Securities, the
         Holders of Trust Preferred Securities shall use all reasonable efforts
         to promptly appoint a Successor Delaware Trustee or Successor Property
         Trustee, as the case may be, if the Property Trustee or the Delaware
         Trustee delivers an instrument of resignation in accordance with this
         Section 5.6.

         (e) If no Successor Property Trustee or Successor Delaware Trustee
         shall have been appointed and accepted appointment as provided in this
         Section 5.6 within 60 days after delivery to the other Trustees, the
         Sponsor, the Trust and, after an Event of Default has occurred and is
         continuing, the Holders of the Trust Preferred Securities of an
         instrument of resignation, the resigning Property Trustee or Delaware
         Trustee, as applicable, may petition any court of competent
         jurisdiction for appointment of a Successor Property Trustee or

         notice, if any, as it may deem proper, appoint a Successor Property
         Trustee or Successor Delaware Trustee, as the case may be.

         (f) No Property Trustee or Delaware Trustee shall be liable for the

         Delaware Trustee, as the case may be.

         (g) At the time of the resignation or removal of the Property Trustee
         or the Delaware Trustee, the Sponsor shall pay to such Trustee any
         amounts that may be owed to such Trustee pursuant to Section 10.4.

Section 5.7 Vacancies Among Trustees. If a Trustee ceases to hold office for any
reason and the number of Trustees is not reduced pursuant to Section 5.1, or if
the number of Trustees is increased pursuant to Section 5.1, a vacancy shall
occur. A resolution certifying the existence of such vacancy by the
Administrative Trustees or, if there are more than two Administrative Trustees,
a majority of the Administrative Trustees shall be conclusive evidence of the
existence of such vacancy. The vacancy shall be filled with a Trustee appointed
in accordance with Section 5.6.

Section 5.8 Effect of Vacancies. The death, resignation, retirement, removal,
bankruptcy, dissolution, liquidation, incompetence or incapacity to perform the
duties of a Trustee shall not operate to dissolve, terminate or annul the Trust.
Whenever a vacancy among the Administrative Trustees shall occur, until such
vacancy is filled by the appointment of an Administrative Trustee in accordance
with Section 5.6, the Administrative Trustees in office, regardless of their
number, shall have all the powers granted to the Administrative Trustees and
shall discharge all the duties imposed upon the Administrative Trustees by this
Agreement.

Section 5.9 Meetings. If there is more than one Administrative Trustee, meetings
of the Administrative Trustees shall be held from time to time upon the call of
any Administrative Trustee. Regular meetings of the Administrative Trustees may
be held at a time and place fixed by resolution of the Administrative Trustees.
Notice of any in-person meetings of the Administrative 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 meetings of the Administrative 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
a 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 an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative 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 Agreement, any action of the Administrative Trustees
may be taken at (i) a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, provided that a Quorum is present, or (ii) without a
meeting and without prior notice by the unanimous written consent of the
Administrative Trustees. In the event there is only one Administrative Trustee,
any and all action of such Administrative Trustee shall be evidenced by a
written consent of such Administrative Trustee.

         contemplated in Section 3.6.

         (b) The Administrative 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 Administrative Trustees or otherwise
         as the Administrative 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 5.11 Merger, Conversion, Consolidation or Succession to Business. Any
Person into which the Property Trustee or the Delaware Trustee, as the case may
be, may be merged or converted or with which either may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Property Trustee or the Delaware Trustee, as the case may be, shall be a party,
or any Person succeeding to all or substantially all the corporate trust
business of the Property Trustee or the Delaware Trustee, as the case may be,
shall be the successor of the Property Trustee or the Delaware Trustee, as the
case may be, hereunder, provided such Person shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or any
further act on the part of any of the parties hereto; provided however, that
such successor shall promptly notify the Sponsor (except that a Successor
Delaware Trustee shall file an appropriate amendment to the Certificate of Trust
of the Trust, if required by the Statutory Trust Act).

                                  DISTRIBUTIONS

Other Document (including any interest or premium on or the principal of the

the Property Trustee shall distribute such income, cash, securities and other
property to the Holders of the Securities in accordance with the terms of the
Securities they hold as set forth in this Agreement, including the Terms and
Conditions. The Property Trustee shall make the distributions on the Trust
Preferred Securities and the Common Securities in accordance with the relative
rights, preferences and privileges that apply to each of those classes of
Securities as set forth in this Agreement.

                  liquidation amount and premium, if any, of the Securities are

                  (xvi) the ranking of the Trust Preferred Securities and the

                  Securities or the Common Securities permitted by Delaware law
                  and any deletions from or modifications or additions to this
                  Agreement, including any Events of Default or covenants of any
                  of the parties hereto, in respect of the Securities, provided
                  no covenant in this Agreement may be modified without the
                  consent of the party giving such covenant.

         (c) The Certificates shall be in the forms prepared by the Sponsor and
         signed on behalf of the Trust by at least one Administrative Trustee.
         Such signature shall be the manual or facsimile signature of any
         present or any future Administrative Trustee. In case any
         Administrative Trustee who shall have signed any of the Securities
         shall cease to be such Administrative Trustee before the Certificates
         so signed shall be delivered by the Trust, such Certificates
         nevertheless may be delivered as though the person who signed such
         Certificates had not ceased to be such Administrative Trustee; and any
         Certificate may be signed on behalf of the Trust by any persons who, at
         the actual date of execution of such Certificate, shall be an
         Administrative Trustee of the Trust, although at the date of the
         execution and delivery of the Agreement any such person was not such an
         Administrative Trustee. Certificates shall be printed, lithographed or
         engraved or may be produced in any other manner as is reasonably
         acceptable to the Administrative Trustee, as evidenced by such
         individual's execution thereof, and may have such letters, numbers or
         other marks of identification or designation and such legends or
         endorsements as the Administrative Trustee that signs such Certificates
         may deem appropriate, or as may be required to comply with any law or
         with any rule or regulation of any stock exchange on which Securities
         may be listed, or to conform to usage.

                  A Trust Preferred Security Certificate shall not be valid
         until authenticated by the manual signature of an authorized officer of
         the Property Trustee. Such signature shall be conclusive evidence that
         a Trust Preferred Security Certificate has been authenticated under
         this Agreement. Each Trust Preferred Security Certificate shall be
         dated the date of its authentication by the Property Trustee. Each
         Common Security Certificate shall be dated the date it is executed by
         an Administrative Trustee. Upon a written order of the Trust signed by
         one Administrative Trustee, the Property Trustee shall authenticate
         Trust Preferred Security Certificates, provided the aggregate
         liquidation amount or number of the Trust Preferred Securities shall
         not exceed the aggregate liquidation amount or number, as the case may
         be, of Trust Preferred Securities designated in the Terms and
         Conditions, as such liquidation amount or number, as the case may be,
         may be reduced by redemptions, repayments, exchanges, conversions or
         liquidating distributions.

                  The Property Trustee may appoint an authenticating agent
         acceptable to the Administrative Trustees to authenticate Trust
         Preferred Security Certificates. An authenticating agent may
         authenticate Trust Preferred Security Certificates whenever the

         Property Trustee may do so. Each reference in this Agreement to
         authentication by the Property Trustee includes authentication by such
         agent. An authenticating agent has the same rights as the Property
         Trustee to deal with the Sponsor or an Affiliate of the Sponsor.

         (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 Agreement, the
         Securities so issued shall be deemed to be validly issued, fully paid
         and, subject to Section 10.1(b), non-assessable.

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

Section 7.2 Paying Agent and Registrar. In the event that the Trust Preferred
Securities are not in book-entry only form:

         (a) The Trust shall maintain in the Borough of Manhattan, The City of
         New York, an office or agency where the Trust Preferred Securities may
         be presented for payment ("Paying Agent"), and any such Paying Agent
         shall comply with Section 317(b) of the Trust Indenture Act. The
         Administrative Trustees on behalf of the Trust may appoint the Paying
         Agent and may appoint one or more additional paying agents in such
         other locations as it shall determine. The term "Paying Agent" includes
         any additional paying agent. The Administrative Trustees on behalf of
         the Trust may change any Paying Agent without prior notice to any
         Holder. The Administrative Trustees on behalf of the Trust shall notify
         the Property Trustee of the name and address of any Paying Agent not a
         party to this Agreement. If the Administrative Trustees on behalf of
         the Trust fail to appoint or maintain another entity as Paying Agent,
         the Property Trustee shall act as such. The Administrative Trustees on
         behalf of the Trust or any of its Affiliates (including the Sponsor)
         may act as Paying Agent. The Property Trustee at its Corporate Trust
         Office shall initially act as Paying Agent for the Trust Preferred
         Securities and the Common Securities.

         (b) The Trust shall maintain in the Borough of Manhattan, The City of
         New York, an office or agency where Trust Preferred Securities may be
         presented for registration of transfer or exchange ("Registrar"). The
         Registrar shall keep a register of the Trust Preferred Securities and
         of their transfer or exchange. The Administrative Trustees on behalf of
         the Trust may appoint the Registrar and may appoint one or more
         co-registrars in such other locations as it shall determine. The term
         "Registrar" includes any such additional registrar. The Administrative
         Trustees on behalf of the Trust may change any Registrar or
         co-registrar without prior notice to any Holder. The Administrative
         Trustees on behalf of the Trust shall notify the Property Trustee of
         the name and address of any Agent not a party to this Agreement. If the
         Administrative Trustees on behalf of the

                                       38
<PAGE>

         Trust fail to appoint or maintain another entity as Registrar, the
         Property Trustee shall act as such. The Trust or any of its Affiliates
         (including the Sponsor) may act as Registrar. The Administrative
         Trustees on behalf of the Trust shall act as Registrar for the Common
         Securities.

         (c) Notwithstanding Sections 3.6(b)(vi) and 3.6(l), the Trust initially
         appoints the Property Trustee as Registrar for the Trust Preferred
         Securities and authorizes it to execute and deliver letters, documents
         and instruments with DTC and other Clearing Agencies relating to the
         Trust Preferred Securities.

                              TERMINATION OF TRUST

Section 8.1 Termination of Trust.

         (a) The Trust shall dissolve and its affairs shall be wound up upon the
         first of the following to occur:

                  (i) (other than in connection with a merger, consolidation or
                  similar transaction not prohibited by this Agreement or any
                  Trust Property) upon the filing of a certificate of
                  dissolution or its equivalent with respect to the Sponsor [or
                  the Debenture Issuer]; or the revocation of the Sponsor's [or
                  the Debenture Issuer's] charter and the expiration of 90 days
                  after the date of revocation without a reinstatement thereof;

                  (ii) upon the entry of a decree of judicial dissolution of the
                  Trust;

                  (iii) when all the Securities shall have been called for
                  redemption, repayment, conversion or exchange and the amounts
                  necessary for redemption, repayment, conversion or exchange
                  thereof shall have been distributed to the Holders in
                  accordance with the terms of this Agreement and the
                  Securities;

                  (iv) upon the liquidation of the Trust and the distribution to
                  the Holders of all amounts they are required to receive in
                  accordance with the terms of this Agreement and the
                  Securities;

                  (v) the expiration of the term of the Trust provided in
                  Section 3.13 of this Agreement; and

                  (vi) any other event specified in the Terms and Conditions.

         (b) As soon as is practicable after the occurrence of an event referred
         to in Section 8.1(a) and upon completion of the winding-up of the
         Trust, an Administrative Trustee shall file a certificate of
         cancellation of the Certificate of Trust of the Trust with the
         Secretary of State of the State of Delaware.

         (c) The provisions of Section 4.4 and Article X shall survive the
         termination of the Trust.

                                   ARTICLE IX
                              TRANSFER OF INTERESTS

Section 9.1 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 Agreement
         and in the terms of the Securities. To the fullest extent permitted by
         law, any transfer or purported transfer of any Security not made in
         accordance with this Agreement shall be null and void.

         (b) Subject to this Article IX and the Terms and Conditions, Trust
         Preferred Securities shall be freely transferable.

         (c) Subject to this Article IX, the Sponsor and any Related Party may
         only transfer Common Securities to the Sponsor or a Related Party of
         the Sponsor; provided that, any such transfer is subject to the
         condition precedent that the transferor obtain the written opinion of
         nationally recognized independent counsel experienced in such matters
         that such transfer would not cause more than an insubstantial risk
         that:

                  (i) the Trust would not be classified for U.S. Federal income
                  tax purposes as a grantor trust; and

                  (ii) the Trust would be an Investment Company or the
                  transferee would become an Investment Company.

Section 9.2 Transfer or Exchange of Certificates. The Registrar shall provide
for the registration of Certificates and of transfers or exchanges of
Certificates, which shall be effected without charge but only upon payment (with
such indemnity as the Administrative Trustees may require) in respect of any tax
or other government charges that may be imposed in relation to it. The Trust
will not be required to register or cause to be registered the transfer of its
trust preferred securities after they have been converted, exchanged, repaid,
redeemed or called for redemption. Upon surrender for registration of transfer
or exchange of any Certificate at the Corporate Trust Office of the Property
Trustee, the applicable Registrar shall cause one or more new Certificates to be
issued in the name of the designated transferee or transferees or the party
requesting the exchange, as the case may be. Every Certificate surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer or exchange in form satisfactory to the applicable
Registrar and duly executed by the Holder or such Holder's attorney duly
authorized in writing. Each Certificate surrendered for registration of transfer
or exchange shall be canceled by the applicable Registrar. A transferee of a
Certificate and the recipient of one or more Certificates issued in exchange for
cancelled Certificates shall be entitled to the rights and subject to the
obligations of a Holder hereunder upon the receipt by such transferee or
recipient of a Certificate or Certificates duly executed by an Administrative
Trustee and, in the case of a Trust Preferred Security Certificate,
authenticated by the Property Trustee. By acceptance of a Certificate, each
transferee shall be deemed to have agreed to be bound by this Agreement.

                                       40

Section 9.3 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 Trust shall
have actual or other notice thereof.

Section 9.4 Book Entry Interests. Unless otherwise specified in the Terms and
Conditions, the Trust Preferred Securities Certificates, on original issuance,
shall be issued in the form of one or more, fully registered, global Trust
Preferred Security Certificates (each a "Global Certificate"), to be delivered
to DTC, the initial Clearing Agency, by, or on behalf of, the Trust. Each such
Global Certificate shall initially be registered on the books and records of the
Trust in the name of Cede & Co., the nominee of DTC, and no Trust Preferred
Security Beneficial Owner will receive a definitive Trust Preferred Security
Certificate representing such Trust Preferred Security Beneficial Owner's
interests in any Global Certificate, except as provided in Section 9.7. Except
for the definitive Trust Preferred Security Certificates issued to the Trust
Preferred Security Beneficial Owners pursuant to Section 9.7 or in accordance
with the Terms and Conditions:

         (a) the provisions of this Section 9.4 shall be in full force and
         effect;

         (b) the Trust, the Trustees and any Agent shall be entitled to deal
         with the Clearing Agency for all purposes of this Agreement (including
         the payment of distributions on any Global Certificate and receiving
         approvals, votes or consents hereunder) as the Holder of the Trust
         Preferred Securities and the sole holder of any Global Certificate and
         shall have no obligation to the Trust Preferred Security Beneficial
         Owners;

         (c) to the extent that the provisions of this Section 9.4 conflict with
         any other provisions of this Agreement other than the Terms and
         Conditions, the provisions of this Section 9.4 shall control; and

         (d) the rights of the Trust Preferred Security Beneficial Owners shall
         be exercised only through the Clearing Agency and shall be limited to
         those established by law and agreements between the Trust Preferred
         Security Beneficial Owners and the Clearing Agency and/or the Clearing
         Agency Participants to receive and transmit payments and other
         distributions on the Global Certificates to such Clearing Agency
         Participants. DTC will make book entry transfers among the Clearing
         Agency Participants; provided, that, solely for the purposes of
         determining whether the Holders of the requisite amount of Trust
         Preferred Securities have voted on any matter provided for in this
         Agreement, 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 Clearing Agency setting forth the
         Trust Preferred Security Beneficial Owners' votes or assigning the
         right to vote on any matter to any other Persons either in whole or in
         part.

Section 9.5 Notices to Clearing Agency. Whenever a notice or other communication
to the Trust Preferred Security Holders is required under this Agreement, unless
and until definitive fully registered Trust Preferred Security Certificates
shall have been issued to the Trust Preferred

                                       41
<PAGE>

Security Beneficial Owners pursuant to Section 9.7 or otherwise, the
Administrative Trustees shall give all such notices and communications specified
herein to be given to the Trust Preferred Security Holders to the Clearing
Agency, and shall have no notice obligations to the Trust Preferred Security
Beneficial Owners.

Section 9.6 Appointment of Successor Clearing Agency. If any Clearing Agency
elects to discontinue its services as securities depositary with respect to the
Trust Preferred Securities, the Administrative Trustees may, in their sole
discretion, appoint a successor Clearing Agency with respect to such Trust
Preferred Securities.

Section 9.7 Definitive Trust Preferred Security Certificates. If:

         (a) a Clearing Agency elects to discontinue its services as securities
         depositary with respect to the Trust Preferred Securities and a
         successor Clearing Agency is not appointed within 90 days after such
         discontinuance pursuant to Section 9.6; or

         (b) the Administrative Trustees elect after consultation with the
         Sponsor to terminate the book-entry system through the Clearing Agency
         with respect to the Trust Preferred Securities, then:

                  (i) definitive fully registered Trust Preferred Security
                  Certificates shall be prepared and executed by the
                  Administrative Trustees and authenticated by the Property
                  Trustee on behalf of the Trust with respect to such Trust
                  Preferred Securities; and

                  (ii) upon surrender of any Global Certificate by the Clearing
                  Agency, accompanied by registration instructions, the
                  Administrative Trustees shall cause definitive fully
                  registered Trust Preferred Securities Certificates to be
                  executed, and the Property Trustee shall cause such Trust
                  Preferred Securities Certificates to be authenticated and
                  delivered to Trust 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,
                  said instructions of the Clearing Agency. The definitive fully
                  registered Trust Preferred Security Certificates shall be
                  printed, lithographed or engraved or may be produced in any
                  other manner as is reasonably acceptable to the Administrative
                  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
                  Administrative Trustees and the Property Trustee 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 regulation of any stock exchange on which Trust
                  Preferred Securities may be listed, or to conform to usage.

Section 9.8 Mutilated, Destroyed, Lost or Stolen Certificates. If:

         (a) any mutilated Certificate shall be surrendered to the
         Administrative Trustees, or if the Administrative Trustees shall
         receive evidence to their satisfaction of the destruction, loss or
         theft of any Certificate; and

                                       42
<PAGE>

         (b) there shall be delivered to the Administrative Trustees and the
         Property Trustee such security or indemnity as may be required by them
         to keep each of the Trustees and the Trust harmless, then, in the
         absence of notice that such Certificate shall have been acquired by a
         protected purchaser, any Administrative Trustee on behalf of the Trust
         shall execute and deliver, and, in the case of a Trust Preferred
         Securities Certificate, the Property Trustee shall authenticate, in
         exchange for or in lieu of any such mutilated, destroyed, lost or
         stolen Certificate, a new Certificate of like denomination. In
         connection with the issuance of any new Certificate under this Section
         9.8, the Administrative Trustees and the Property Trustee 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 X
                      LIMITATION OF LIABILITY OF HOLDERS OF
                         SECURITIES, TRUSTEES OR OTHERS

Section 10.1 Liability.

         (a) Except as expressly set forth in this Agreement, the Debentures,
         any other instrument or agreement, the Securities Guarantees and the
         terms of the Securities, [neither] the Sponsor [nor the Debenture
         Issuer] shall [not] be:

                  (i) personally liable for the return of any portion of the
                  capital contributions (or any return thereon) of the Holders
                  of the Securities, which shall be made solely from assets of
                  the Trust; or

                  (ii) required to pay to the Trust or to any Holder of
                  Securities any deficit upon dissolution of the Trust or
                  otherwise.

         (b) The Sponsor, as the [Debenture Issuer] [Debenture Guarantor], shall
         be liable for all of the debts and obligations of the Trust (other than
         with respect to the Securities) to the extent not satisfied out of the
         Trust's assets.

         (c) Pursuant to Section 3803(a) of the Statutory Trust Act, the Holders
         of the Trust Preferred Securities shall be entitled to the same
         limitation of personal liability extended to stockholders of private
         corporations for profit organized under the General Corporation Law of
         the State of Delaware.

Section 10.2 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

                                       43
<PAGE>

         to be within the scope of the authority conferred on such Indemnified
         Person by this Agreement or by law, except that an Indemnified Person
         shall be liable for any such loss, damage or claim incurred by reason
         of such Indemnified Person's gross negligence (or, in the case of the
         Property Trustee, negligence), bad faith 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.

Section 10.3 Fiduciary Duty.

         (a) To the extent that, at law or in equity, an Indemnified Person has
         duties (including fiduciary duties) and liabilities relating thereto to
         the Trust or to any other Covered Person, an Indemnified Person acting
         under this Agreement shall not be liable to the Trust or to any other
         Covered Person for its good faith reliance on the provisions of this
         Agreement. The provisions of this Agreement, to the extent that they
         restrict the duties and liabilities of an Indemnified Person otherwise
         existing at law or in equity (other than the duties imposed on the
         Property Trustee under the Trust Indenture Act), are agreed by the
         parties hereto to replace such other duties and liabilities of such
         Indemnified Person.

         (b) Unless otherwise expressly provided herein:

                  (i) whenever a conflict of interest exists or arises between
                  any Covered Persons and any Indemnified Person; or

                  (ii) whenever this Agreement or any other instrument or
                  agreement contemplated herein or therein provides that an
                  Indemnified Person shall act in a manner that is, or provides
                  terms that are, fair and reasonable to the Trust or any Holder
                  of Securities, the Indemnified Person shall resolve such
                  conflict of interest, take such action or provide such terms,
                  considering in each case the relative interest of each party
                  (including its own interest) to such conflict, agreement,
                  transaction or situation and the benefits and burdens relating
                  to such interests, any customary or accepted industry
                  practices, and any applicable generally accepted accounting
                  practices or principles. In the absence of bad faith by the
                  Indemnified Person, the resolution, action or term so made,
                  taken or provided by the Indemnified Person shall not
                  constitute a breach of this Agreement or any other agreement
                  contemplated herein or of any duty or obligation of the
                  Indemnified Person at law or in equity or otherwise.

         (c) Whenever in this Agreement an Indemnified Person is permitted or
         required to make a decision:

                                       44
<PAGE>

                  (i) in its "sole discretion" or under a grant of similar
                  authority, the Indemnified Person shall be entitled to
                  consider such interests and factors as it desires, including
                  its own interests, and shall have no duty or obligation to
                  give any consideration to any interest of or factors affecting
                  the Trust or any other Person; or

                  (ii) in its "good faith" or under another express standard,
                  the Indemnified Person shall act under such express standard
                  and shall not be subject to any other or different standard
                  imposed by this Agreement or by applicable law.

Section 10.4 Indemnification.

                  (a) (i) The Sponsor shall indemnify, to the fullest extent
                  permitted by law, any Company Indemnified Person who was or is
                  a party or is threatened to be made a party to any threatened,
                  pending or completed action, suit or proceeding, whether
                  civil, criminal, administrative or investigative (other than
                  an action by or in the right of the Trust) by reason of the
                  fact that he is or was a Company Indemnified Person against
                  expenses (including reasonable attorneys' fees), judgments,
                  fines and amounts paid in settlement actually and reasonably
                  incurred by him in connection with such action, suit or
                  proceeding if he acted in good faith and in a manner he
                  reasonably believed to be in or not opposed to the best
                  interests of the Trust, and, with respect to any criminal
                  action or proceeding, had no reasonable cause to believe his
                  conduct was unlawful. The termination of any action, suit or
                  proceeding by judgment, order, settlement, conviction, or upon
                  a plea of nolo contendere or its equivalent, shall not, of
                  itself, create a presumption that the Company Indemnified
                  Person did not act in good faith and in a manner which he
                  reasonably believed to be in or not opposed to the best
                  interests of the Trust, and, with respect to any criminal
                  action or proceeding, had reasonable cause to believe that his
                  conduct was unlawful.

                  (ii) The Sponsor shall indemnify, to the fullest extent
                  permitted by law, any Company Indemnified Person who was or is
                  a party or is threatened to be made a party to any threatened,
                  pending or completed action or suit by or in the right of the
                  Trust to procure a judgment in its favor by reason of the fact
                  that he is or was a Company Indemnified Person against
                  expenses (including reasonable attorneys' fees) actually and
                  reasonably incurred by him in connection with the defense or
                  settlement of such action or suit if he acted in good faith
                  and in a manner he reasonably believed to be in or not opposed
                  to the best interests of the Trust and except that no such
                  indemnification shall be made in respect of any claim, issue
                  or matter as to which such Company Indemnified Person shall
                  have been adjudged to be liable to the Trust unless and only
                  to the extent that the Court of Chancery of Delaware or the
                  court in which such action or suit was brought shall determine
                  upon application that, despite the adjudication of liability
                  but in view of all the circumstances of the case, such person
                  is fairly and reasonably entitled to indemnity for such
                  expenses which such Court of Chancery or such other court
                  shall deem proper.

                  (iii) Any indemnification under paragraphs (i) and (ii) of
                  this Section 10.4(a) (unless ordered by a court) shall be made
                  by the Sponsor only as authorized in the specific case upon a
                  determination that indemnification of the Company Indemnified
                  Person is proper in the circumstances because he has met the
                  applicable standard of conduct set forth in paragraphs (i) and
                  (ii). Such determination shall be made (1) by the
                  Administrative Trustees by a majority vote of a Quorum
                  consisting of such Administrative Trustees who were not
                  parties to such action, suit or proceeding, (2) if such a
                  Quorum is not obtainable, or, even if obtainable, if a Quorum
                  of disinterested Administrative Trustees so directs, by
                  independent legal counsel in a written opinion, or (3) by the
                  Common Security Holder of the Trust.

                  (iv) Expenses (including reasonable attorneys' fees) incurred
                  by a Company Indemnified Person in defending a civil,
                  criminal, administrative or investigative action, suit or
                  proceeding referred to in paragraphs (i) and (ii) of this
                  Section 10.4(a) shall be paid by the Sponsor in advance of the
                  final disposition of such action, suit or proceeding upon
                  receipt of an undertaking by or on behalf of such Company
                  Indemnified Person to repay such amount if it shall ultimately
                  be determined that such person is not entitled to be
                  indemnified by the Sponsor as authorized in this Section
                  10.4(a). Notwithstanding the foregoing, no advance shall be
                  made by the Sponsor if a determination is reasonably and
                  promptly made (i) by the Administrative Trustees by a majority
                  vote of a Quorum of disinterested Administrative Trustees,
                  (ii) if such a Quorum is not obtainable, or, even if
                  obtainable, if a Quorum of disinterested Administrative
                  Trustees so directs, by independent legal counsel in a written
                  opinion or (iii) the Common Security Holder of the Trust,
                  that, based upon the facts known to the Administrative
                  Trustees, independent legal counsel or Common Security Holder
                  at the time such determination is made, such person acted in
                  bad faith or in a manner that such person did not believe to
                  be in or not opposed to the best interests of the Trust, or,
                  with respect to any criminal proceeding, that such Company
                  Indemnified Person believed or had reasonable cause to believe
                  his conduct was unlawful. In no event shall any advance be
                  made in instances where the Administrative Trustees,
                  independent legal counsel or Common Security Holder reasonably
                  determine that such person deliberately breached such person's
                  duty to the Trust or its Common or Trust Preferred Security
                  Holders.

                  (v) The indemnification and advancement of expenses provided
                  by, or granted pursuant to, the other paragraphs of this
                  Section 10.4(a) shall not be deemed exclusive of any other
                  rights to which those seeking indemnification and advancement
                  of expenses may be entitled under any agreement, vote of
                  shareholders or disinterested directors of the Sponsor or
                  Trust Preferred Security Holders of the Trust or otherwise,
                  both as to action in his official capacity and as to action in
                  another capacity while holding such office. All rights to
                  indemnification under this Section 10.4(a) shall be deemed to
                  be provided by a contract between the Sponsor and each Company
                  Indemnified Person who serves in such capacity at any time
                  while this Section 10.4(a) is in effect. Any repeal or

                                       46
<PAGE>

                  modification of this Section 10.4(a) shall not affect any
                  rights or obligations then existing.

                  (vi) The Sponsor or the Trust may purchase and maintain
                  insurance on behalf of any person who is or was a Company
                  Indemnified Person against any liability asserted against him
                  and incurred by him in any such capacity, or arising out of
                  his status as such, whether or not the Sponsor would have the
                  power to indemnify him against such liability under the
                  provisions of this Section 10.4(a).

                  (vii) For purposes of this Section 10.4(a), references to the
                  "Trust" shall include, in addition to the resulting or
                  surviving entity, any constituent entity (including any
                  constituent of a constituent) absorbed in a consolidation or
                  merger, so that any person who is or was a director, trustee,
                  officer or employee of such constituent entity, or is or was
                  serving at the request of such constituent entity as a
                  director, trustee, officer, employee or agent of another
                  entity, shall stand in the same position under the provisions
                  of this Section 10.4(a) with respect to the resulting or
                  surviving entity as such person would have with respect to
                  such constituent entity if its separate existence had
                  continued.

                  (viii) The indemnification and advancement of expenses
                  provided by, or granted pursuant to, this Section 10.4(a)
                  shall, unless otherwise provided when authorized or ratified,
                  continue as to a person who has ceased to be a Company
                  Indemnified Person and shall inure to the benefit of the
                  successors, heirs, executors and administrators of such a
                  person.

         (b) To the fullest extent permitted by law, the Sponsor agrees to
         indemnify each Fiduciary Indemnified Person for, and to hold each
         Fiduciary Indemnified Person harmless against, any loss, liability or
         expense to the extent incurred without gross negligence (or in the case
         of the Property Trustee, pursuant to Section 3.9, negligence), bad
         faith or willful misconduct on its part, arising out of or in
         connection with the acceptance or administration of the trust or trusts
         hereunder, including the costs and expenses (including reasonable legal
         fees and expenses) of defending itself against or investigating any
         claim or liability in connection with the exercise or performance of
         any of its powers or duties hereunder. The provisions of this Section
         10.4(b) shall survive the satisfaction and discharge of this Agreement
         and any resignation or removal of the Property Trustee or the Delaware
         Trustee, as the case may be.

Section 10.5 Outside Businesses. Any Covered Person, the Sponsor, the Delaware
Trustee and the Property Trustee (subject to Section 5.3(c)) 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 of Securities shall have no rights by
virtue of this Agreement 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. No Covered Person, the Sponsor, the Delaware Trustee or the Property
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 any Covered Person, the
Sponsor, the Delaware Trustee

                                       47
<PAGE>

and the Property 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 Covered Person, the Delaware
Trustee and the Property 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 depositary 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.

Section 10.6 Trustees' Fees and Expenses. Each Trustee shall receive as
compensation for its services hereunder such fees and expenses as have been
separately agreed upon before the date hereof between the Sponsor and such
Trustee, and each Trustee shall be entitled to be reimbursed by the Sponsor for
other reasonable expenses hereunder, including the reasonable compensation,
expenses and disbursements of such agents, representatives, experts and counsel
as such Trustee may employ in connection with the exercise and performance of
its rights and duties hereunder.

                                   ARTICLE XI
                                   ACCOUNTING

Section 11.1 Fiscal Year. The fiscal year ("Fiscal Year") of the Trust shall be
the calendar year, or such other year as is required by the Code.

Section 11.2 Certain Accounting Matters.

         (a) At all times during the existence of the Trust, the Administrative
         Trustees on behalf of the Trust shall keep, or cause to be kept, full
         books of account, records and supporting documents, all of 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 U.S.
         Federal income tax purposes.

         (b) The Administrative Trustees, on behalf of the Trust, shall cause to
         be duly prepared and delivered to each of the Holders of Securities,
         any annual U.S. Federal income tax information statement required by
         the Code and the Treasury Regulations, 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 Administrative
         Trustees on behalf of the Trust shall endeavor to deliver all such
         statements within 30 days after the end of each Fiscal Year of the
         Trust.

         (c) The Administrative Trustees on behalf of the Trust shall cause to
         be duly prepared and filed with the appropriate taxing authority an
         annual U.S. Federal income tax return, on a Form 1041 or such other
         form required by U.S. Federal income tax law, and any other annual
         income tax returns required to be filed by the Trust with any state or
         local taxing authority.

Section 11.3 Banking. The Administrative Trustees, on behalf of 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 for the benefit of holders of
Securities of funds in respect of Trust Property shall be

                                       48
<PAGE>

made directly to the Property Trustee Account and no other funds of the Trust
shall be deposited in the Property Trustee Account. The sole signatories for
such accounts shall be designated by the Administrative Trustees; provided,
however, that the Property Trustee shall designate the signatories for the
Property Trustee Account.

Section 11.4 Withholding. The Administrative Trustees on behalf of the Trust
shall comply with all withholding requirements under U.S. Federal, state and
local law. The Trust shall request, and 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 Administrative
Trustees on behalf of 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 required to be withheld was not withheld
from actual distributions made, the Trust may reduce subsequent distributions by
the amount of such withholding.

                                   ARTICLE XII

                           Securities); and

                  (iii) to the extent the result of such amendment would be to:

                           (A) cause the Trust to fail to continue to be
                           classified for purposes of U.S. federal income
                           taxation as a grantor trust;

                           (B) reduce or otherwise adversely affect the powers
                           of the Property Trustee in contravention of the Trust

                           (C) cause the Trust to be deemed to be an Investment
                           Company required to be registered under the
                           Investment Company Act;

         (c) after the Trust has issued any Securities that remain outstanding,
         without the consent of the Holders of a Majority in liquidation amount
         of each class of Securities affected, this Agreement may not be amended
         for any reason in a manner that would adversely affect the rights,
         privileges or preferences of such class of Securities, provided that,
         except as may be provided in the Terms and Conditions, without the
         consent of each Holder of Securities affected thereby, this Agreement
         may not be amended to:

                  (i) change the Distribution rate, or manner of calculation of
                  the Distribution rate, amount, timing or currency or otherwise

         of the Holders of any class of Securities may be called at any time by
         the Administrative Trustees (or as provided in the terms of the
         Securities) to consider and act on any matter on which Holders of
         Securities are entitled to act under the terms of this Agreement, the
         terms of the Securities or the rules of any stock exchange on which the

         Administrative Trustees shall call a meeting of the Holders if directed
         to do so by the Holders of at least 10% in liquidation amount of
         Securities. Such direction shall be given by delivering to the
         Administrative Trustees one or more calls in a writing stating that the
         signing Holders of Securities wish

         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
         Securities specified 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 provisions shall apply to meetings of Holders
         of Securities:

                  (i) notice of any such meeting shall be given to all the
                  Holders of Securities having a right to vote thereat at least
                  seven days and not more than 60 days before the date of such
                  meeting. Whenever a vote, consent or approval of the Holders
                  of Securities is permitted or required under this Agreement,
                  the terms of the Securities or the rules of any stock exchange
                  on which the Trust 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 and without prior notice if a consent in
                  writing setting forth the action so taken is signed by the
                  Holders of Securities owning not less than the minimum amount
                  of Securities in liquidation amount 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
                  Administrative Trustees may specify that any written ballot
                  submitted to the Holder of Securities for the purpose of
                  taking any action without a meeting shall be returned to the
                  Trust within the time specified by the Administrative
                  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 Securities
                  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 Securities
                  executing it. Except as otherwise provided herein, 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 Administrative Trustees or by such other
                  Person that the Administrative Trustees may designate; and

                  (iv) unless the Statutory Trust Act, this Agreement, the terms
                  of the Securities, the Trust Indenture Act or the listing
                  rules of any stock exchange on which the Trust Preferred
                  Securities are then listed or trading otherwise provides, the
                  Administrative Trustees, in their sole discretion, shall
                  establish all other

                  (2) Designation and Number.

                  (a) Trust Preferred Securities. Preferred securities of the
Trust, with an aggregate liquidation amount with respect to the assets of the
Trust of up to ___________________ Dollars ($___________) and a liquidation
amount with respect to the assets of the Trust of $_________ per security, are
hereby designated for the purposes of identification only as "______% Trust
Preferred Securities" (the "Trust Preferred Securities"). The Trust Preferred

                                       A-3
<PAGE>

Security Certificates evidencing the Trust Preferred Securities shall be
substantially in the form of Exhibit A-I to the Agreement, with such changes and
additions thereto or deletions therefrom as may be required by applicable law or
the rules of any stock exchange on which the Trust Preferred Securities are
listed or to conform to ordinary usage, custom or practice.

                  (b) Common Securities. Common Securities of the Trust, with an
aggregate liquidation amount with respect to the assets of the Trust of up
to____________________ Dollars ($____________) and a liquidation amount with
respect to the assets of the Trust of $_______ per security, are hereby
designated for the purposes of identification only as "______% Common
Securities" (the "Common Securities"). The Common Security Certificates
evidencing the Common Securities shall be substantially in the form of Exhibit
A-2 to the Agreement, with such changes and additions thereto or deletions
therefrom as may be required by applicable law or to conform to ordinary usage,
custom or practice.

                  (c) The maximum liquidation amount of Trust Preferred
Securities and Common Securities referred to above excludes Securities
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of other Securities pursuant to Section 9.2, 9.7 or 9.8 of the
Agreement, upon repayment, redemption, exchange [or conversion] into other
securities in accordance with its terms.

                  (d) The Preferred Securities and the Common Securities
represent undivided beneficial interests in the assets of the Trust.

                  (e) In connection with the purchase of the Securities, the
Sponsor will deposit in the Trust, and the Trust will purchase, respectively, as
trust assets, Debentures of the Sponsor having an aggregate principal amount
equal to $[ ], 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.

                  (3) Distributions.

                  (a) Cash distributions will be payable on each Security at the
rate per annum of _____% (the "Coupon Rate") of the stated liquidation amount of
$______ per Security [until ________________________, and at the Reset Rate
thereafter], such rate[s] being the rate[s] of interest payable on the
Debentures. Distributions in arrears for more than one quarter will bear
interest thereon compounded quarterly at the rate of ______% [until
__________________________ and at the Reset Rate thereafter] (to the extent
permitted by applicable law). The term "Distributions" as used herein includes
such cash distributions and any such interest payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds available therefor. The amount of Distributions payable for
any period will be computed for any full quarterly Distribution period on the
basis of a 360-day year consisting of twelve 30-day months, and for any period
shorter than a full quarterly Distribution period for which Distributions are
computed, Distributions will be computed on the basis of the actual number of
days elapsed per 30-day month.

<PAGE>

                  (b) Distributions on the Securities will be cumulative, will
accumulate from _____________________, and will be payable quarterly in arrears,
on __________________, _____________________ and _________________________ of
each year, commencing on _____________________, when, as and if available for
payment, except as otherwise described below (a "Distribution Payment Date")
except as otherwise described below. [So long as the Debenture Issuer shall not
be in default in the payment of interest on the Debentures, the Debenture Issuer
has the right under the Indenture to defer payments of interest on the
Debentures by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), during which Extension Period no interest shall be due and
payable on the Debentures, provided that no Extension Period shall last beyond
the Stated Maturity of the Debentures. As a consequence of such deferral,
Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly to the
extent permitted by law during any such Extension Period. Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period, together with
all such previous and further extensions thereof, may not exceed 20 consecutive
quarters or extend beyond the Stated Maturity of the Debentures. Any interest
accrued on the Debentures during an Extension Period shall be paid Pro Rata to
holders of Debentures on the first payment date following the Extension Period
and the Payment Amount shall be paid Pro Rata to the Holders on the first
Distribution Payment Date following the Extension Period. Upon the termination
of any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.
If (i) the Debenture Issuer shall exercise its right to defer payment of
interest as provided above and the Extension Period is continuing, or (ii) there
shall have occurred any Event of Default, as defined in the Indenture, or (iii)
there shall have occurred any Event of Default, as defined in the Trust
Preferred Securities Guarantee, then (a) the Debenture Issuer shall not (i)
declare or pay any dividends or distributions on, or redeem, purchase, acquire
or make a liquidation payment with respect to, any of the Debenture Issuer's
Capital Stock or (ii) make any payment of principal of or interest on or repay,
repurchase or redeem any debt securities of the Debenture Issuer that rank
equally with or junior to the Debentures or make any guarantee payments with
respect to any guarantee by the Debenture Issuer of the debt securities of any
Subsidiary of the Debenture Issuer that by its terms ranks equally with or
junior to the Debentures (other than (a) dividends or distributions in Common
Stock, (b) any declaration of a dividend in connection with the implementation
of a Rights Plan, the issuance of any Capital Stock of the Debenture Issuer
under any Rights Plan or the redemption or repurchase of any rights distributed
pursuant to a Rights Plan, (c) payments under any Guarantee relating to the
Trust Preferred Securities, and (d) purchases of Common Stock related to the
issuance of Common Stock or rights under the Debenture Issuer's dividend
reinvestment plan, or under any of the Debenture Issuer's benefit plans for its
directors, officers, employees, consultants or advisors).]

                  (c) Distributions on the Securities will be payable to the
Holders thereof as they appear on the books and records of the Trust at the
close of business on the Business Day immediately preceding each of the relevant
payment dates on the Securities. [Subject to any applicable laws and regulations
and the provisions of the Agreement, each such payment in respect of the Trust
Preferred Securities will be made as described under the heading
"_________________" in the Prospectus Supplement dated _____________________ to
the Prospectus dated ______________________ (collectively, the "Prospectus") of
the Trust relating

                                      A-5
<PAGE>

to the Registration Statement on Form S-3 (file no._________________________) of
the Sponsor and the Trust.] The relevant record dates for the Common Securities
shall be the same record date as for the Trust Preferred Securities. If the
Trust Preferred Securities shall not continue to remain in book-entry only form
or are not in book-entry only form at issuance, the relevant record dates for
the Trust Preferred Securities shall conform to the rules of any securities
exchange on which the securities are listed and, if none, as shall be selected
by the Administrative Trustees, which dates shall be at least more than one, but
less than 60 Business Days before the relevant payment dates, which payment
dates correspond to the interest payment dates on the Debentures. Distributions
payable on any Securities that are not punctually paid on any Distribution
payment date, as a result of the Debenture Issuer [or the Debenture Guarantor,
as the case may be,] having failed to make a payment under the Debentures, will
cease to be payable to the Person in whose name such Securities are registered
on the relevant record date, and such defaulted Distribution will instead be
payable to the Person in whose name such Securities are registered on 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 the
Debenture Issuer has elected to make a full or partial payment of interest
accrued on the Debentures on such Distribution Payment Date. If any date on
which Distributions are payable on the 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. [So long as the Holder of any Trust Preferred Securities is the
Collateral Agent, the payment of Distributions on such Trust Preferred
Securities held by the Collateral Agent will be made at such place and to such
account as may be designated by the Collateral Agent.] Distributions on the
Securities will be paid by the Trust.

                  [(d) The Coupon Rate on the Securities (as well as the
interest rate on the Debentures) will be reset on the third Business Day
immediately preceding the Purchase Contract Settlement Date to the Reset Rate
(which Reset Rate will be in effect on and after the Purchase Contract
Settlement Date). On the Reset Announcement Date, the Reset Spread and the
Two-Year Benchmark Treasury to be used to determine the Reset Rate will be
announced by the Sponsor. On the Business Day immediately following the Reset
Announcement Date, the Holders of Securities will be notified of such Reset
Spread and Two-Year Benchmark Treasury by the Sponsor. Such notice shall be
sufficiently given to Holders of Securities if published in an Authorized
Newspaper.]

                  [(e) Not later than 7 calendar days nor more than 15 calendar
days prior to the Reset Announcement Date, the Sponsor will request DTC (as
defined herein) or its nominee (or any successor Clearing Agency or its nominee)
by first-class mail, postage prepaid, to notify the Trust Preferred Security
Beneficial Owner or Clearing Agency Participants holding Trust Preferred
Securities of such Reset Announcement Date and the procedures to be followed by
such Holders who intend to settle their obligation under the Purchase Contract
with separate cash.]

                  (f) In the event that there is any money or other property
held by or for the Trust that is not accounted for hereunder, such property
shall be distributed Pro Rata (as defined herein) among the Holders of the
Securities.

                  (4) Liquidation Distribution Upon Dissolution.

                  In the event of any voluntary or involuntary liquidation,
dissolution, winding-up or other termination of the Trust, the Holders of the
Securities on the date of the dissolution will be entitled to receive out of the
assets of the Trust, after satisfaction (or reasonable provision for
satisfaction) of liabilities to creditors, such amounts as determined by Section
8.1(a) of the Agreement, which shall be distributed on a Pro Rata basis to the
Holders of the Securities in exchange for such Securities (such amount being
"Liquidation Distribution").

                  (5) Redemption and Distribution

                  (a) Upon the redemption of the Debentures in whole (but not in
part), at maturity, the proceeds from such redemption shall, after satisfaction
of liabilities to creditors of the Trust, be simultaneously applied to redeem
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so redeemed at a redemption price of $_____
per Security plus an amount equal to accumulated and unpaid Distributions
thereon at the date of the repayment, payable in cash.

                  (b) If an Investment Company Event (as defined herein) shall
occur and be continuing the Administrative Trustees shall dissolve the Trust and
after satisfaction of liabilities to creditors, cause Debentures held by the
Property Trustee, having an aggregate principal amount equal to the aggregate
stated liquidation amount of, with an interest rate equal to the rate of _____%,
[if on or prior to ____________________, and the Reset Rate thereafter,] and
accrued and unpaid interest equal to accumulated and unpaid Distributions on,
and having the same record date for payment as the Securities, to be distributed
to the Holders of the Securities in liquidation of such Holders' interests in
the Trust on a Pro Rata basis, within 90 days following the occurrence of such
Investment Company Event (the "90 Day Period"); provided, however, that, if at
the time there is available to the Trust the opportunity to eliminate, within
the 90 Day Period, the Investment Company Event by taking some ministerial
action, such as filing a form or making an election, or pursuing some other
similar reasonable measure that will have no adverse effect on the Trust, the
Debenture Issuer, the Sponsor or the Holders of the Securities and will involve
no material cost ("Ministerial Action"), the Administrative Trustees will pursue
such Ministerial Action in lieu of dissolution.

                  "Investment Company Event" means that the Administrative
Trustees shall have received an opinion of independent counsel experienced in
such matters (an "Investment Company Event Opinion") to the effect that, as a
result of the occurrence of a change in law or regulation or a written 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"),
which Change in 1940 Act Law becomes effective on or after the date of the
Prospectus, there is a more than an insubstantial risk that the Trust is or will
be considered an investment company that is required to be registered under the
Investment Company Act.

                  (c) If a Tax Event shall occur and be continuing, the
Debentures are redeemable at the option of the Debenture Issuer, in whole but
not in part, on not less than 30 days nor more than 60 days notice ("Tax Event
Redemption"). If the Debenture Issuer redeems the Debentures upon the occurrence
and continuance of a Tax Event, the proceeds from such redemption shall

                                      A-7
<PAGE>

simultaneously be applied by the Trust to redeem the Securities having an
aggregate stated liquidation amount equal to the aggregate principal amount of
the Debentures so redeemed at a redemption price (the "Redemption Price"), per
Security, equal to the Redemption Amount plus any accumulated and unpaid
Distributions thereon to the date of such redemption. [If, following the
occurrence of a Tax Event, the Debenture Issuer exercises its option to redeem
the Debentures, the Debenture Issuer shall appoint the Quotation Agent to
assemble the Treasury Portfolio in consultation with the Company.] To the extent
the Redemption Price is received by the Property Trustee, the Property Trustee
will distribute, to the record Holder of the Securities the Redemption Price
payable in liquidation of such Holder's interests in the Trust.

                  "Tax Event" means the receipt by the Administrative Trustees
of an opinion of a nationally recognized independent tax counsel experienced in
such matters to the effect that, 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 affecting taxation, (b) any amendment to or change
in an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority or (c) any
interpretation or pronouncement that provides for a position with respect to
such laws or regulations that differs from the generally accepted position on
the date the Securities are issued, which amendment or change is effective or
which interpretation or pronouncement is announced on or after the date of
issuance of the Securities under the Agreement, there is more than an
insubstantial risk that (i) interest payable by the Debenture Issuer on the
Debentures would not be deductible, in whole or in part, by the Debenture Issuer
for federal income tax purposes or (ii) the Trust would be subject to more than
a de minimis amount of other taxes, duties or other governmental charges.

                  ["Treasury Portfolio" means, with respect to the Applicable
Principal Amount of Debentures (a) if the Tax Event Redemption Date occurs prior
to ________________ a portfolio of zero-coupon U.S. Treasury Securities
consisting of (i) interest or principal strips of U.S. Treasury Securities which
mature on or prior to ________________, in an aggregate amount equal to the
Applicable Principal Amount and (ii) with respect to each scheduled interest
payment date on the Debentures that occurs after the Tax Event Redemption Date,
interest or principal strips of U.S. Treasury Securities which mature on or
prior to that date in an aggregate amount equal to the aggregate interest
payment that would be due on the Applicable Principal Amount of the Debentures
on such date, and (b) if the Tax Event Redemption Date occurs after
___________________, a portfolio of zero-coupon U.S. Treasury Securities
consisting of (i) principal or interest strips of U.S. Treasury Securities which
mature on or prior to _________________ in an aggregate amount equal to the
Applicable Principal Amount and (ii) with respect to each scheduled interest
payment date on the Debentures that occurs after the Tax Event Redemption Date,
interest or principal strips of such U.S. Treasury Securities which mature on or
prior to such date in an aggregate amount equal to the aggregate interest
payment that would be due on the Applicable Principal Amount of the Debentures
on such date.]

                  ["Applicable Ownership Interest" means, with respect to [title
of security] and the U.S. Treasury Securities in the Treasury Portfolio, (A) a
1/____,or ____%, undivided beneficial ownership interest in a U.S. Treasury
Security in the amount of $1,000 included in such Treasury Portfolio payable on
or prior to ______________________ and (B) for each scheduled interest payment
date on the Debentures that occurs after the Tax Event Redemption Date, a _____%

                                      A-8
<PAGE>

undivided beneficial ownership interest in a $1,000 face amount of such U.S.
Treasury Security which is a principal or interest strip maturing on such date.]

                  ["Applicable Principal Amount" means either (i) if the Tax
Event Redemption Date occurs prior to ______________________, the aggregate
principal amount of the Debentures corresponding to the aggregate stated
liquidation amount of the Trust Preferred Securities [which are components of
title of security]] on the Tax Event Redemption Date or (ii) if the Tax Event
Redemption occurs on or after ________________________ the aggregate principal
amount of the Debentures corresponding to the aggregate stated liquidation
amount of the Trust Preferred Securities outstanding on such Tax Event
Redemption Date.]

                  ["Redemption Amount" means for each Debenture, the product of
(i) the principal amount of such Debenture and (ii) a fraction whose numerator

Principal Amount.]

                  ["Treasury Portfolio Purchase Price" means the lowest
aggregate price quoted by a primary U.S. government securities dealer in New
York City (a "Primary Treasury Dealer") to the Quotation Agent on the third
Business Day immediately preceding the Tax Event Redemption Date for the
purchase of the Treasury Portfolio for settlement on the Tax Event Redemption
Date.]

                  ["Quotation Agent" means (i) _________________________________
and its respective successors, provided, however, that if the foregoing shall
cease to be a Primary Treasury Dealer, the Sponsor shall substitute therefor
another Primary Treasury Dealer and (ii) any other Primary Treasury Dealer
selected by the Sponsor.]

                  On and from the date fixed by the Administrative Trustees for
a Tax Event Redemption or any distribution of Debentures upon dissolution of the
Trust: (i) the Securities shall no longer be deemed to be outstanding, (ii) DTC
or its nominee (or any successor Clearing Agency or its nominee) or the record
Holder of the Trust Preferred Securities, will receive a registered global
certificate or certificates representing the Debentures to be delivered upon
such distribution and any certificates representing Securities, except for
certificates representing Trust Preferred Securities held by DTC or its nominee
(or any successor Clearing Agency or its nominee), will be deemed to represent
beneficial interests in the Debentures having an aggregate principal amount
equal to the aggregate stated liquidation amount of $_______, with an interest
rate of _____% [if on or prior to ________________________, and at the Reset
Rate thereafter,] and accrued and unpaid interest equal to accrued and unpaid
Distributions on such Securities until such certificates are presented to the
Debenture Issuer or its agent for transfer or reissue.

                  (6) Redemption or Distribution Procedures.

                  (a) Notice of any redemption (other than in connection with
the maturity of the Debentures) of, or notice of distribution of Debentures in
exchange for, the Securities (a "Redemption/Distribution Notice") will be given
by the Property Trustee by mail to each Holder of Securities to be redeemed or
exchanged not fewer than 30 nor more than 60 days before the date fixed for
redemption or exchange thereof which, in the case of a redemption, will be the
Tax Event Redemption Date. For purposes of the calculation of the date of
redemption or exchange and the dates on which notices are given pursuant to this
Section 6(a), a Redemption/Distribution Notice

                                      A-9
<PAGE>

shall be deemed to be given on the day such notice is first mailed by
first-class mail, postage prepaid, to Holders of Securities. Each
Redemption/Distribution Notice shall be addressed to the Holders of 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.

                  (b) If Securities are to be redeemed and the Property Trustee
gives a Redemption/Distribution Notice, which notice may only be issued if the
Debentures are redeemed as set out in this Section 6 (such notice will be
irrevocable), then (A) while the Trust Preferred Securities are in book-entry
only form, with respect to the Trust Preferred Securities, by 12:00 noon, New
York City time, on the redemption date, provided that the Debenture Issuer has
paid the Property Trustee a sufficient amount of cash in connection with the
related redemption or maturity of the Debentures by 10:00 A.M. New York City
time on such Redemption Date, the Property Trustee will deposit irrevocably with
DTC or its nominee (or any successor Clearing Agency or its nominee), [the
Purchase Contract Agent or the Collateral Agent, as applicable,] funds
sufficient to pay the applicable Redemption Price with respect to the Trust
Preferred Securities and will give DTC, [the Purchase Contract Agent or the
Collateral Agent, as applicable,] irrevocable instructions and authority to pay
the Redemption Price to the Holders of the Trust Preferred Securities so called
for redemption, and (B) with respect to Trust Preferred Securities issued in
definitive form and Common Securities, provided that the Debenture Issuer has
paid the Property Trustee 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 Securities by check mailed
to the address of the relevant Holder appearing on the books and records of the
Trust. Notwithstanding the foregoing, so long as the Holder of any Trust
Preferred Securities is the Collateral Agent or the Purchase Contract Agent, the
payment of the Redemption Price in respect of such Trust Preferred Securities
held by the Collateral Agent or the Purchase Contract Agent shall be made no
later than 12:00 noon, New York City time, on the Tax Event Redemption Date by
check or wire transfer in immediately available funds at such place and to such
account as may be designated by the Collateral Agent or the Purchase Contract
Agent. 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 date of such deposit, or on the redemption date, as applicable,
distributions will cease to accumulate on the Securities so redeemed and all
rights of Holders of such Securities so called for redemption will cease, except
the right of the Holders of such Securities to receive the Redemption Price, but
without interest on such Redemption Price. Neither the Administrative Trustees
nor the Trust shall be required to register or cause to be registered the
transfer of any Securities that have been so called for redemption. If any date
fixed for redemption of 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 (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 any Securities is
improperly withheld or refused and not paid either by the Property Trustee or by
the Sponsor as guarantor pursuant to the relevant Securities Guarantee,
Distributions on such Securities will continue to accumulate from the original
redemption date to the actual date of payment, in which case the actual payment
date will be considered the date fixed

                                      A-10
<PAGE>

for redemption for purposes of calculating the Redemption Price and such
Securities shall cease to be outstanding.

                  (c) Redemption/Distribution Notices shall be sent by the
Property Trustee on behalf of the Trust to (A) in respect of the Trust Preferred
Securities, DTC or its nominee (or any successor Clearing Agency or its nominee)
if the Global Certificates have been issued or, if Definitive Trust Preferred
Security Certificates have been issued, to the Holder thereof, and (B) in
respect of the Common Securities, to the Holder thereof.

                  (d) Subject to the foregoing and applicable law (including,
without limitation, U.S. federal securities laws) the Sponsor or any of its
subsidiaries may at any time and from time to time purchase outstanding Trust
Preferred Securities by tender, in the open market or by private agreement.

                  [(7) Repayment at Option of Holders.]

                  [(a) If a Failed Remarketing (as described in Section 5.3(b)
of the Purchase Contract Agreement and incorporated herein by reference) has
occurred, each holder of Securities who holds such Securities on the day
immediately following the Purchase Contract Settlement Date, shall have the
right to require the Trust to repay all or a portion of such Securities owned by
such holder (the "Put Option") on __________________________ (the "Put Option
Exercise Date"), upon at least three Business Days' prior notice, at a repayment
price of $_________ per Security plus an amount equal to the accrued and unpaid
Distributions thereon to the date of payment (the "Put Option Repayment Price").

                  (b) The Trust shall obtain funds to pay the Put Option
Repayment Price of Securities being repaid under the Put Option through
presentation by the Property Trustee, on behalf of the Trust, to the Debenture
Issuer, pursuant to the right of the holder of the Debentures to require the
Debenture Issuer to repay all or a portion of the Debentures on the Put Option
Exercise Date, Debentures in an aggregate principal amount equal to the
aggregate stated liquidation amount of such Securities for repayment on the Put
Option Exercise Date at the Debenture Repayment Price.

                  (c) In order for the Securities to be repaid on the Put Option
Exercise Date, the Trust must receive on or prior to 4:00 p.m. on the third
Business Day immediately preceding the Put Option Exercise Date, at the
Corporate Trust Office of the Property Trustee, the Securities to be repaid with
the form entitled "Option to Elect Repayment" on the reverse thereof or
otherwise accompanying such Security duly completed. Any such notice received by
the Trust shall be irrevocable. All questions as to the validity, eligibility
(including time of receipt) and acceptance of the Securities for repayment shall
be determined by the Trust, whose determination shall be final and binding.

                  (d) Payment of the Put Option Repayment Price to Holders of
Securities shall be made at the Corporate Trust Office of the Property Trustee,
provided that the Property Trustee has received from the Debenture Issuer a
sufficient amount of cash in connection with the related repayment of the
Debentures no later than 1:00 p.m., New York City time, on the Put Option
Exercise Date by check or wire transfer in immediately available funds at such
place and to such

                                      A-11
<PAGE>

account as may be designated by such Holders. If the Property Trustee holds
immediately available funds sufficient to pay the Put Option Repayment Price of
such Securities, then, immediately prior to the close of business on the Put
Option Exercise Date, such Securities will cease to be outstanding and
distributions thereon will cease to accumulate, whether or not Securities are
delivered to the Property Trustee, and all other rights of the Holder in respect
of the Securities, including the Holder's right to require the Trust to repay
such Securities, shall terminate and lapse (other than the right to receive the
Put Option Repayment Price but without interest on such Put Option Repayment
Price). Neither the Administrative Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Securities for which
repayment has been elected. If payment of the Put Option Repayment Price in
respect of Securities is (i) improperly withheld or refused and not paid either
by the Property Trustee or by the Sponsor as guarantor pursuant to the
Securities Guarantees, or (ii) not paid by the Property Trustee as the result of
an Event of Default with respect to the Debentures presented for repayment as
described in paragraph 6(b), Distributions on such Securities will continue to
accumulate, from the original Put Option Exercise Date to the actual date of
payment, in which case the actual payment date will be considered the Put Option
Exercise Date for purposes of calculating the Put Option Repayment Price.

                  (e) The Debenture Issuer will request, not later than 10 nor
more than 15 calendar days prior to ___________________ (the date on which some
or all of the Trust Preferred Securities could be remarketed in the manner
described in Section 5.3(b) of the Purchase Contract Agreement and incorporated
herein by reference) that DTC notify the Trust Preferred Securities Holders of
such remarketing and of the procedures that must be followed if a Holder of
Trust Preferred Securities wishes to exercise such Holder's rights with respect
to the Put Option.]

                  (8) Voting Rights - Trust Preferred Securities.

                  (a) Except as provided under Sections 8(b) and 10 and as
otherwise required by law and the Agreement, including these Terms and
Conditions, the Holders of the Trust Preferred Securities will have no voting
rights.

                  (b) Subject to the requirements set forth in this paragraph,
the Holders of a Majority in liquidation amount of the Trust Preferred
Securities, acting separately as a class may direct the time, method, and place
of conducting any proceeding for any remedy available to the Property Trustee,
or the exercise of any trust or power conferred upon the Property Trustee under
the Agreement, including (i) directing 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) waiving any past default and its consequences that is waivable
under the Indenture, (iii) exercising any right to rescind or annul a Agreement
that the principal of all the Debentures shall be due and payable, or (iv)
consenting to any amendment, modification or termination of the Indenture or the
Debentures where such consent shall be required, provided, however, that, where
a consent or action under the Indenture specifically would require the consent
or act of the Holders of greater than a majority of the Holders in principal
amount of Debentures affected thereby (a "Super Majority"), the Property Trustee
may only give such consent or take such action at the written direction of the
Holders of at least the proportion in liquidation amount of the Trust Preferred
Securities which the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding. The Property

                                      A-12
<PAGE>

Trustee shall not revoke any action previously authorized or approved by a vote
of the Holders of the Trust Preferred Securities. Other than with respect to
directing the time, method and place of conducting any remedy available to the
Property Trustee or the Debenture Trustee as set forth above, the Property
Trustee shall not take any action in accordance with the directions of the
Holders of the Trust Preferred Securities under this paragraph unless the
Property Trustee has obtained an opinion of tax counsel to the effect that for
the purposes of U.S. federal income tax the Trust will not be classified as
other than a grantor trust on account of such action. If the Property Trustee
fails to enforce its rights under the Debentures after a Holder of Trust
Preferred Securities has made a written request, such Holder of Trust Preferred
Securities may, to the fullest extent permitted by applicable law, institute a
legal proceeding directly against the Debenture Issuer [or the Debenture
Guarantor, as the case may be,] to enforce the Property Trustee's rights under
the Debentures without first instituting a legal proceeding against the Property
Trustee or any other Person. Notwithstanding the foregoing, if an Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Debenture Issuer [or the Debenture Guarantor, as the case may
be,] to pay interest or principal on the Debentures on the date such interest or
principal is otherwise payable (or in the case of redemption, on the redemption
date), then a Holder of Trust Preferred Securities may directly institute a
proceeding for enforcement of payment to such Holder of the principal of or
interest on the Debentures having a principal amount equal to the aggregate
liquidation amount of the Trust Preferred Securities of such Holder on or after
the respective due date specified in the Debentures. Except as provided in the
preceding sentence, the Holders of Trust Preferred Securities shall not exercise
directly any other remedy available to the holders of the Debentures.

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

                  No vote or consent of the Holders of the Trust Preferred
Securities will be required for the Trust to repay and cancel Trust Preferred
Securities or to distribute the Debentures in accordance with the Agreement and
the terms of the Securities. Notwithstanding that Holders of Trust Preferred
Securities are entitled to vote or consent under any of the circumstances
described above, any of the Trust Preferred Securities that are owned by the
Sponsor or any Affiliate of the Sponsor 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

                  (9) Voting Rights - Common Securities.

                  (a) Except as provided under Sections 9(b), 9(c) and 10 and as
otherwise required by law and the Agreement, including these Terms and
Conditions, the Holders of the Common Securities will have no voting rights.

<PAGE>

                  (b) The Holders of the Common Securities are entitled, in
accordance with Article V of the Agreement, to vote to appoint, remove or
replace any Trustee or to increase or decrease the number of Trustees.

                  (c) Subject to Section 2.6 of the Agreement and only after any
Event of Default with respect to the Trust Preferred Securities has been cured,
waived, or otherwise eliminated and subject to the requirements of the second to
last sentence of this paragraph, the Holders of a Majority in liquidation amount
of the Common Securities, voting separately as a class, may 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 Agreement, including (i) directing 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 the Indenture, or (iii) exercise any right to rescind or annul a
Agreement that the principal of all the Debentures shall be due and payable,
provided that, where a consent or action under the Indenture specifically would
require the consent or act of the Holders of a Super Majority, the Property
Trustee may only give such consent or take such action at the written direction
of the Holders of at least the proportion in liquidation amount of the Common
Securities which the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding. Pursuant to this Section 8(c),
the Property Trustee shall not revoke any action previously authorized or
approved by a vote of the Holders of the Trust Preferred Securities. Other than
with respect to directing the time, method and place of conducting any remedy
available to the Property Trustee or the Debenture Trustee as set forth above,
the Property Trustee shall not take any action in accordance with the directions
of the Holders of the Common Securities under this paragraph unless the Property
Trustee has obtained an opinion of tax counsel to the effect that for the
purposes of U.S. federal income tax the Trust will not be classified as other
than a grantor trust on account of such action. If the Property Trustee fails to
enforce its rights under the Agreement, any Holder of Common Securities may
institute a legal proceeding directly against any Person to enforce the Property
Trustee's rights under the Agreement, without first instituting a legal
proceeding against the Property Trustee or any other Person.

                  Any approval or direction 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 in the Trust or
pursuant to written consent. The Administrative Trustees will cause a notice of
any meeting at which Holders of Common Securities are entitled to vote 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, (ii) a
description of any resolution proposed for adoption at such meeting on which
such Holders are entitled to vote and (iii) instructions for the delivery of
proxies.

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

                  (10) Amendments to Agreement and Indenture.

<PAGE>

                  (a) In addition to any requirements under Section 12.1 of the
Agreement, if any proposed amendment to the Agreement provides for, or the
Administrative Trustees otherwise propose to effect, (i) any action that would
materially adversely affect the powers, preferences or special rights of the
Securities, whether by way of amendment to the Agreement or otherwise, or (ii)
the dissolution of the Trust, other than as described in Section 8.1 of the
Agreement or these Terms and Conditions, then the Holders of outstanding
Securities as a class will be entitled to vote on such amendment or proposal
(but not on any other amendment or proposal) and such amendment or proposal
shall not be effective except with the approval of the Holders of at least a
Majority in liquidation amount of the Securities, voting together as a single
class; provided, however, if any amendment or proposal referred to in clause (i)
above would adversely affect only the Trust Preferred Securities or only 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 a Majority in liquidation amount of such class of
Securities.

                  (b) 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 on 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 and 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, however, that where a consent under the Indenture specifically
would require a Super Majority, the Property Trustee may only give such consent
at the direction of the Holders of at least the proportion in liquidation amount
of the Securities which the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding; provided, further, that the
Property Trustee shall not take any action in accordance with the directions of
the Holders of the Securities under this Section 10(b) unless (i) the Property
Trustee has obtained an opinion of tax counsel to the effect that for the
purposes of U.S. federal income tax the Trust will not be classified as other
than a grantor trust on account of such action or (ii) such action would not
reduce or otherwise adversely affect powers of the Property Trustee or cause the
Trust to be deemed an "investment company" which is required to be registered
under the Investment Company Act of 1940.

                  (11) Pro Rata.

                  A reference in these terms of the 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
under the Agreement has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the Trust
Preferred Securities pro rata according to the aggregate liquidation amount of
Trust Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Trust Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Trust 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.

                  (12) Ranking.

                  The Trust Preferred Securities rank pari passu and payment
thereon shall be made Pro Rata with the Common Securities except that, where an
Event of Default occurs and is continuing under the Indenture in respect of the
Debentures held by the Property Trustee, the rights of Holders of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption and otherwise are subordinated to the rights to payment of the
Holders of the Trust Preferred Securities.

                  (13) Acceptance of Securities Guarantee and Indenture.

                  Each Holder of Trust Preferred Securities and Common
Securities by the acceptance thereof, agrees to the provisions of the Trust
Preferred Securities Guarantee and the Common Securities Guarantee,
respectively.

                  (14) No Preemptive Rights.

                  The Holders of the Securities shall have no preemptive or
other similar rights to subscribe for any additional securities.

                  (15) Additional Provisions

                  [Include additional provisions for conversion, exchange or
otherwise, if any.]

                  (16) Miscellaneous.

                  These terms constitute a part of the Agreement.

                  The Sponsor will provide a copy of the Agreement, the Trust
Preferred Securities Guarantee or the Common Securities Guarantee (as may be
appropriate), and the Indenture to a Holder without charge on written request to
the Sponsor at its principal place of business.

                  IN WITNESS WHEREOF, the undersigned has caused these Terms and
Conditions to be executed as of ________________________.

                  FORM OF TRUST PREFERRED SECURITY CERTIFICATE

[NOTE: This is a form of Trust Preferred Security Certificate. The actual Trust
    Preferred Security Certificate may vary substantially from this form, as
    contemplated by Section 7.1(b) of the form of Amended and Restated Trust
                                   Agreement.]

This Trust Preferred Security is a Global Certificate within the meaning of the
Agreement hereinafter referred to and is registered in the name of The
Depository Trust Company (the "Depositary") or a nominee of the Depositary. This
Trust Preferred Security is exchangeable for Trust Preferred Securities
registered in the name of a person other than the Depositary or its nominee only

Trust Preferred Security (other than a transfer of this Trust Preferred Security
as a whole by the Depositary to a nominee of the Depositary or by a nominee of
the Depositary to the Depositary or another nominee of the Depositary) may be

                          [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Trust Preferred Security will be fixed at
a rate per annum of ____% (the "Coupon Rate") of the stated liquidation amount
of $_____ per Trust Preferred Security, such rate being the rate of interest
payable on the Debentures to be held by the Property Trustee. Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the rate of _____% [until [____________________], and at the Reset
Rate thereafter] (to the extent permitted by applicable law). The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has actually received and holds
funds available therefor. The amount of Distributions payable for any period
will be computed for any full quarterly Distribution period on the basis of a
360-day year consisting of twelve 30-day months, and for any period shorter than
a full quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days elapsed
per 30-day month.

         Except as otherwise described below, Distributions on the Trust
Preferred Securities will be cumulative, will accumulate from the date of
original issuance and will be payable quarterly in arrears, on
[_____________________________________________ of each year, commencing on
___________________], _______________to holders of record, if in book-entry only
form, one Business Day prior to such payment date, which payment dates shall
correspond to the interest payment dates on the Debentures. In the event that
the Trust Preferred Securities are not in book-entry form, the record date will
conform to the rules of any securities exchange on which the securities are
listed and, if none, as shall be selected by the Administrative Trustees, which
dates will be more than one, but less than 60, Business Days before the relevant
payment date, which date shall correspond to the interest payment dates of the
Debentures. [The Debenture Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period from time to time
on the Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and, as a consequence of such deferral,
quarterly Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures. Payments of accrued Distributions will be payable to Holders as
they appear on the books and records of the Trust on the first record date after
the end of the Extension Period. Upon the termination of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.]

         The Trust Preferred Securities shall be redeemable as provided in the
Agreement.

                          [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Common Security will be fixed at a rate
per annum of _____% (the "Coupon Rate") of the stated liquidation amount of
$_______ per Common Security, such rate being the rate of interest payable on
the Debentures to be held by the Property Trustee. Distributions in arrears for
more than one quarter will bear interest thereon compounded quarterly at the
rate of _____% [until [__________________________________], and at the Reset
Rate thereafter] (to the extent permitted by applicable law). The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has actually received and holds
funds available therefor. The amount of Distributions payable for any period
will be computed for any full quarterly Distribution period on the basis of a
360-day year of twelve 30-day months, and for any period shorter than a full
quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days elapsed
per 30-day month.

         Except as otherwise described below, distributions on the Common
Securities will be cumulative, will accumulate from the date of original
issuance and will be payable quarterly in arrears, on
[___________________________ of each year, commencing on________________],

payments of interest by extending the interest payment period from time to time
on the Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period"), provided that no Extension Period shall last beyond the
date of the maturity of the Debentures and, as a consequence of such deferral,
quarterly Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period. Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity of
the Debentures. Payments of accrued Distributions will be payable to Holders as
they appear on the books and records of the Trust on the first record date after
the end of the Extension Period. Upon the termination of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.]

                              COOPERATION AGREEMENT

         THIS COOPERATION AGREEMENT is made as of the 24th day of June, 2002, by
and between NANOPHASE TECHNOLOGIES CORPORATION, a Delaware corporation, with
offices at 1319 Marquette Drive, Romeoville, Illinois 60446, ("Nanophase") and
RODEL, INC., a Delaware corporation, with offices at 451 Bellevue Road, Newark,
DE 19713 ("Rodel").

                                    RECITALS:

         WHEREAS, Nanophase manufactures and sells nanocrystalline cerium oxides
particles ("Ceria") and/or dispersions of Ceria using proprietary processes (the
"Particles") for potential use in products for chemical mechanical planarization
("CMP") for semiconductor wafers (such use being hereinafter referred to as the
"Field"); and

         WHEREAS, Rodel supplies consumable products, including slurry products
to the CMP market; and

         WHEREAS, Nanophase and Rodel believe that use of Nanophase's Particles
for applications in the Field with Rodel's slurry products will result in
superior products for sale to Rodel's CMP customers; and

         WHEREAS, Rodel desires to purchase, and Nanophase desires to sell, the
Particles for applications in the Field in accordance with the terms and
conditions of this Agreement;

         NOW, THEREFORE, in consideration of the foregoing premises and the
mutual covenants and promises hereinafter set forth, the parties agree as
follows:

1.   Cooperation

     (a)  Nanophase and Rodel mutually agree to use all commercially reasonable
          efforts to cooperate with one another to develop one or more
          commercial slurry products incorporating the Particles for
          applications in the Field (the "Development Product").

<PAGE>

     Unless otherwise agreed, each party shall be responsible for its own
     expenses in connection with the development effort.

(b)  Without limiting Rodel's general obligation of cooperation under subsection
     (a), above, Rodel undertakes to (i) provide Nanophase with target
     specifications, performance data and analytical assistance as may be agreed
     to characterize Development Product performance, (ii) test and evaluate
     Development Product samples provided by Nanophase and provide feedback as
     to the results thereof to Nanophase in a timely manner, (iii) keep
     Nanophase regularly advised of the general market situation applicable to
     the Development Products, and (iv) include Nanophase business and technical
     personnel in meetings with business and technical personnel at Rodel's
     customers, as appropriate, to discuss and promote the Particles and the
     Development Products.

(c)  Without limiting Nanophase's general obligation of cooperation under
     subsection (a), above, Nanophase undertakes to (i) provide Rodel with
     reasonable research samples of the Development Product for testing and
     evaluation as may be agreed, together with related physical, chemical and
     other information, (ii) devote sufficient resources (including equipment
     and personnel) as may be agreed to provide for the development effort, and
     (iii) provide agreed technical support to Rodel and its customers as to the
     use of the Particles and the Development Products.

(d)  Any intellectual property created or invented after the date of this
     Agreement in connection with the Development Product shall be owned as
     follows, regardless of whether such intellectual property was created or
     invented by personnel of Nanophase, Rodel or both of them: (i) Nanophase
     shall own all such intellectual property to the extent related or
     applicable to the manufacture of Particles for applications in the Field,
     and (ii) Rodel shall own all such intellectual property to the extent
     related or applicable to slurry formulation and manufacture for CMP
     applications. Each party agrees to notify the other promptly of any
     inventions pertaining to applications in the Field which are created by the
     other or its personnel under this Section, and to cooperate with the other
     and its counsel to take such action and execute such documents as may be
     required or reasonably requested to effect the allocation of rights set
     forth herein, including cooperating with the

<PAGE>

     other in the filing and prosecution of all patent applications resulting
     from any inventions pertaining to applications in the Field in connection
     with the Development Product.

2. Purchase and Sale

         Subject to the terms and conditions of this Agreement, Nanophase will
   sell, and Rodel will purchase, all of Rodel's worldwide requirements for
   Ceria for applications in the Field.

3. Exclusivity

         Subject to Rodel's complying with the purchase minimums stated in
   Section 12(a), the purchase and sale obligations set forth in Section 2 shall
   be mutually exclusive; i.e,, except as specifically otherwise provided
   herein, for the term of this Agreement, Nanophase will not sell or sample
   Ceria Particles for applications in the Field to any manufacturer, seller or
   end user of CMP slurries other than Rodel, and Rodel will not purchase Ceria
   Particles for CMP applications from any manufacturer or supplier other than
   Nanophase. This Section shall not apply to Rodel's purchase of evaluation
   samples in connection with Section 11(b), nor to Nanophase's sale of
   evaluation samples to customers other than Rodel who have submitted purchase
   orders for such samples to Nanophase before the date of this Agreement, but
   not to exceed 1,000 kilograms for applications in the Field.

4. Forecasts and Orders

   (a) Rodel will provide Nanophase with a rolling eighteen-month forecast of
       the volume of its Particle requirements at the start of each calendar
       quarter. The first three months of this forecast shall be firm and
       accompanied by a purchase order for such forecast. Unless otherwise
       agreed, Nanophase need not manufacture more than [ * * * ] of the
       forecasted six-month volume in any single month period.

  (b)  Rodel will give Nanophase six months prior written notice before
       Nanophase will be obliged to either (i) have installed capacity or
       manufacture over [ * * * ] of Particles per annum, or (ii) increase
       production by more than [ * * * ] kilograms of Particles over the
       production for the previous six-month period. Provided that Nanophase is
       given such six-month notice, it will be obliged to manufacture up to
       [ * * * ] kilograms of Particles in the first year of this Agreement.

  (c)  If Rodel requests that Nanophase commit to manufacture an amount of
       Particles in excess of [ * * * ] kilograms per annum, the parties will
       negotiate in good faith a mutually acceptable arrangement for payment of
       the capital expenditures required in order for Nanophase to manufacture
       such increased amount. Any failure of Rodel or Nanophase to agree upon
       such a mutually acceptable arrangement following good faith negotiations
       shall not constitute either (i) an unwillingness by Nanophase to supply
       Rodel with Particles under Section 8(a) of this Agreement, or (ii) a
       breach of any party's obligations under the Agreement.

  (d)  Rodel will submit written purchase orders to Nanophase giving reasonable
       notice which may not be less than three weeks prior to the requested date
       of shipment and specifying the required quantities, shipment dates,
       destinations and other relevant information, and Nanophase will use
       commercially reasonable efforts to fill the orders (including using
       reasonable commercial efforts to fill orders for which Rodel may be
       unable to provide a full three weeks' notice) so that Rodel may meet its
       delivery commitments to its customers.

  (e)  Other provisions applicable to the purchase and sale of the Particles
       shall be as provided in Rodel's standard terms and conditions of sale, to
       the extent not inconsistent with this Agreement.

5. Price and Payment

   (a)  Based on the minimum volumes required for Rodel to maintain exclusivity
        under Section 12(a), the sales price for the Particles shall be
        [ * * * ] If agreed indices for Ceria raw materials show that the costs
        of these materials has significantly changed after 2002, the parties
        will negotiate in good faith to determine the appropriate pricing
        adjustments.

   (b)  Unless otherwise agreed by the parties with respect to any particular
        order, all shipment of Particles shall be F.O.B. Nanophase's facility,
        with title and risk of loss passing at the shipment point. Rodel will
        make payment in full of all Particles conforming to the specifications
        described in Exhibit A within thirty (30) days of receipt of invoice.

6. Warranties

   (a)  Nanophase warrants that (i) to the best of its knowledge, the
        processes Nanophase applies in manufacturing and selling the Particles
        do not infringe upon any patent or trade secret of any third party,
        and (ii) all Particles shipped under this Agreement will conform to
        the specifications agreed upon in writing, including those set forth
        in Exhibit A, as the same may hereafter be amended by the parties (the
        "Specifications"), and (iii) the Particles and their manufacture are
        and shall be in compliance with all applicable laws, rules and
        regulations, the noncompliance with which, if Nanophase is unable to
        cure the noncompliance within 90 days of notification thereof, would
        result in Nanophase's inability to meet its supply obligations under
        this Agreement. If, notwithstanding Nanophase's compliance with its
        warranty given in clause (i) hereof, Nanophase receives notice from a
        third party alleging that its processes infringe a patent or trade
        secret of such third party, then Nanophase and Rodel will consult one
        another in good faith to discuss actions to resolve the claim,
        including possible financial support by Rodel and consideration by
        Nanophase in respect thereof. These warranties are in lieu of all
        other warranties or conditions express or implied. TO THE EXTENT
        ALLOWABLE BY LAW, THIS EXCLUSION OF ALL OTHER WARRANTIES OR CONDITIONS

  * * * Confidential Portions Omitted and Filed Separately with the Commission

<PAGE>

        EXTENDS TO IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABLE QUALITY AND
        FITNESS FOR A PARTICULAR PURPOSE, AND THOSE ARISING BY STATUTE OR
        OTHERWISE IN LAW OR FROM A COURSE OF DEALING OR USAGE OF TRADE.

   (b)  If any Particles fail to comply with the Specifications, Nanophase will,
        at Rodel's option, promptly return or exchange the Particles with
        conforming Particles, or issue a refund or credit of the purchase price.

7. Indemnity

           Each party (the "indemnifying party") agrees to indemnify and
   hold the other party, its parents, subsidiaries, affiliates and permitted
   assigns, and the directors, employees and agents of each of the foregoing
   entities (all, the "indemnified party"), harmless from and against all
   liabilities, claims, damages and expenses (including, without limitation,
   reasonable attorneys' fees) arising out of or in connection with (a) any
   act or omission of the indemnifying party in breach of this Agreement, (b)
   any injury or damage to the extent attributable to the fault or negligence
   of the indemnifying party or (c) violation of any law, rule, regulation or
   order by the indemnifying party related to this Agreement. This Section 7
   shall not apply to relieve either party's liability to the other for breach
   of such party's obligations to the other party under this Agreement.

8. License

   (a)  In the event (i) Nanophase provides written notice to Rodel that
        Nanophase is unwilling to supply Rodel with conforming Particles for
        applications in the Field conforming to the Specifications or (ii)
        Nanophase acknowledges in writing that it is insolvent, or the board
        of directors of Nanophase shall authorize any liquidation or winding
        up of Nanophase, or a petition seeking a receivership or involuntary
        bankruptcy is filed against Nanophase and such petition is not
        dismissed within sixty days after service upon Nanophase, or (iii)
        there is a change of control (as defined in Section 12(c)) of
        Nanophase to a direct competitor of Rodel in the Field, then, in any
        such case, Rodel shall have an exclusive, royalty bearing,
        transferable license to make, have made, use and sell Ceria particles
        for applications in the Field under any and all intellectual property
        owned or controlled by

<PAGE>

       Nanophase or its principals. Such license shall be exercisable by Rodel
       upon written notice and shall be self-executing. If requested by Rodel,
       Nanophase will sell such equipment in its possession or control as
       Nanophase may have available and Rodel may require for full exercise of
       the license rights granted hereunder. The purchase price of any such
       equipment shall [ * * * ]

   (b) In addition to the foregoing, Nanophase agrees to make available the
       reasonable services of personnel it deems appropriate to provide such
       technical assistance as Rodel may reasonably request in connection with
       the manufacture of the Particles for applications in the Field under the
       licensed intellectual property. Nanophase will provide up [ * * * ]

   (c) The license provided in this Section 8 shall bear a royalty payable by
       Rodel to Nanophase [ * * * ]. Aggregate royalties hereunder shall be paid
       on a quarterly basis and shall be accompanied by a written report of the
       quantity of Particles used by Rodel on a monthly basis during the period
       covered by the report. This Section 8 shall survive expiration or
       termination of this Agreement in the event it is invoked by Rodel for a
       reason specified in Sections 12(b)(ii) or 12(c), but not by reason of
       Section 12(b)(i).

9. Confidentiality

          In connection with this Agreement, the parties may from time to time
   exchange certain information and data which the disclosing party deems to be
   confidential information. As used herein, "confidential information" means
   any information disclosed in tangible form which is labeled as
   "confidential", "proprietary" or the like, or, if disclosed orally or
   visually, is confirmed in writing as "confidential", "proprietary" or the
   like within thirty (30) days of original disclosure. Confidential information
   shall not include any information which (a) is or becomes part of the public
   domain by reason other than the unauthorized disclosure of a party hereto,
   (b) the receiving party can demonstrate was already in its possession prior
   to receipt, or (c) was received in good faith from a third party having the
   right to disclose the same, or (d) was independently developed by the
   receiving party as evidenced by the receiving party's written records, or (e)
   is required to be disclosed by law, regulation, judicial

  * * * Confidential Portions Omitted and Filed Separately with the Commission

<PAGE>

     process or administrative order, provided that prompt notice and an
     opportunity to seek a protective order is given to the other party before
     the disclosure of confidential information. Each party agrees to keep in
     confidence and not disclose any confidential information received from the
     other, and further agrees not to use any such information for any purpose
     except as permitted by, or in furtherance of, this Agreement. Nothing in
     this Section 9 is intended to prevent or limit either party's disclosing
     the relationship contemplated by this Agreement in filings with the U.S.
     Securities and Exchange Commission, or other public disclosures, relating
     to publicly traded securities of either party, or the filing of this
     Agreement as a related exhibit, if such party's counsel reasonably
     determines that such disclosure is appropriate, and provided that to the
     extent permitted by law, (i) the party seeking to disclose provides the
     other party with written notice and (ii) Nanophase uses reasonable efforts
     to seek such redactions of confidential information contained herein as
     Rodel may reasonably request.

10.  Force Majeure

               Neither party shall be liable on account of any failure to
     fulfill its obligations hereunder if such fulfillment is delayed, hindered
     or prevented by forces or events beyond its reasonable control, including
     but not limited to fire, flood, labor difficulties, accident, explosion,
     riots, war, acts of God, terrorist acts, threats of terrorism generally
     affecting commerce, shortage of materials, transportation difficulties, and
     other unforeseen supervening events; provided, that the party claiming any
     such cause as an excuse for nonperformance has provided written notice
     thereof to the other party within two weeks of the event that is the basis
     of the failure to perform, together with the anticipated length of the
     delay or failure.

11.  Product Development and Improvement

     (a)  Throughout the term of this Agreement, Nanophase agrees to use
          commercially reasonable efforts and devote reasonable resources to
          maintain the Particles for applications in the Field as "state of the
          art" or better, based on mutually agreed specifications. In addition,
          pursuant to a protocol to be agreed upon between the parties,

<PAGE>

          Nanophase shall provide Rodel with at least seven (7) months' prior
          written notice before implementing any manufacturing process change
          potentially affecting compliance with the Specifications.

     (b)  Notwithstanding any other provision of this Agreement, if Rodel
          determines that Nanophase's Particles do not meet the material
          performance criteria of competitive Particles for a particular
          application in the Field, Rodel shall promptly notify Nanophase in
          writing and give it reasonably sufficient quantities of such
          competitive Particles and documentation of the material deficiency in
          the performance criteria of Nanophase's Particles, including all
          available data substantiating the performance shortfall (the
          "Performance Deficiency Notice"). Nanophase shall thereafter have six
          months to meet or exceed the material performance criteria of the
          competitive particles for the identified application. If Nanophase is
          unable to meet or exceed such criteria, then Rodel shall be free to
          purchase the competitive particle for the particular application. In
          such case, the parties will promptly meet to discuss whether and upon
          what terms to continue this Agreement on an exclusive basis as set
          forth in Sections 2 and 3, hereof. If the parties cannot agree on a
          course of action within 60 days of the commencement of such
          discussions, then this Agreement shall continue on a nonexclusive
          basis in accordance with its terms, and Sections 2, 3 and 12(a) shall
          be deemed accordingly amended, and Section 8 shall be deleted.

12.  Term and Termination

     (a)  This Agreement shall commence on the date first set forth above and
          continue for an initial period of five years; provided, that if as of
          December 31, 2003, [ * * * ], and Rodel has not purchased from
          Nanophase at least [ * * * ] kilograms of Particles, the parties shall
          meet in good faith to discuss the progress to date and possible
          adjustment of any targets, goals or prices previously established with
          respect to development and sale of Particles for applications in the
          Field (the "Adjustment Discussions"). If within thirty (30) days after
          either party has requested Adjustment Discussions, the parties have
          not agreed on an acceptable path forward on an exclusive basis, then
          either party may, by

  * * * Confidential Portions Omitted and Filed Separately with the Commission

<PAGE>

          written notice delivered at the end of such thirty (30) day period,
          declare this Agreement to be nonexclusive, whereupon the exclusivity
          provisions of Sections 2 and 3 hereof shall be deemed void and this
          Agreement shall continue on a nonexclusive basis for the remainder of
          the initial term (the "Exclusivity Termination Procedure"). The
          parties agree to hold similar Adjustment Discussions, and adhere to
          the same Exclusivity Termination Procedure if (i) during 2004, Rodel
          has not purchased from Nanophase at least [ * * * ] kilograms of
          Particles for applications in the Field, or (ii) during 2005, Rodel
          has not purchased from Nanophase at least [ * * * ] kilograms of
          Particles for applications in the Field, or (iii) during subsequent
          years of the initial term of this Agreement, Rodel has not purchased
          from Nanophase agreed quantities of Particles for applications in the
          Field. Subject to Rodel's complying with the purchase minimums stated
          above (or such other quantities as the parties may agree pursuant to
          the Adjustment Discussions), this Agreement will renew automatically
          at the end of the initial term for consecutive additional periods of
          five years each, unless terminated by either party upon written notice
          delivered at least three (3) months prior to the end of any renewal
          period.

     (b)  This Agreement may be terminated at any time prior to expiration upon
          written notice by either party in the event of (i) a material breach
          by the other which is not cured within thirty (30) days after delivery
          of written notice by the nonbreaching party, or (ii) the other party
          is placed in bankruptcy or receivership.

     (c)  This Agreement may also be terminated at any time prior to expiration
          upon written notice by either party in the event of a change of
          control of the other party to an unaffiliated third party. For
          purposes hereof, a "change in control" means a change in the voting
          control of the affected party or its direct or indirect parent. Except
          to the extent a party's counsel reasonably determines that such
          disclosure is prohibited by applicable statute or regulations of the
          U.S. Securities and Exchange Commission, the party affected by a
          change of control shall give the other at least thirty (30) days'
          prior notice of the contemplated change. If the other party does not
          elect to terminate this Agreement as provided by this subsection, this
          Agreement shall continue in accordance with its terms as provided by
          Section 13, below.

13.  Assignment and Succession

              This Agreement shall not be assigned by either party to any third
     party, except to an affiliate of such party (defined, for purposes of this
     Agreement as a company or other legal entity which controls, is controlled
     by, or is under common control with, Rodel or Nanophase, respectively),
     without the other party's prior written consent, which consent shall not be
     unreasonably withheld. This Agreement shall be binding upon, and inure to
     the benefit of, the respective successors by merger or otherwise and
     permitted assigns of each party.

14.  Miscellaneous Provisions

     (a)  This Agreement embodies all the terms and conditions of the agreement
          between the parties hereto with respect to the matters set forth
          herein and supercedes and cancels all previous agreements and
          understandings, whether oral or written, provided that nothing in this
          Agreement shall be deemed to supersede or cancel that certain
          Confidentiality And Non-Use Agreement between Rodel and Nanophase
          dated November 27, 2001 with respect to information disclosed by
          either party to the other prior to the date hereof.

     (b)  The terms of this Agreement may not be modified, waived or discharged
          except by an express declaration in writing signed on behalf of the
          parties hereto by their duly authorized officers and referring
          specifically to this Agreement.

     (c)  The failure of Nanophase or Rodel at any time to require performance
          by the other of any provision hereof shall in no way affect the full
          right to require such performance at any time thereafter, nor shall
          the waiver by Nanophase or Rodel of a breach of any provision hereof
          be taken or held to be a waiver of any succeeding breach of such
          provision or as a waiver of the provision itself.

     (d)  The termination or expiration of this Agreement for any reason shall
          not affect any of the provisions of this Agreement which expressly
          continue in force after its termination or expiration, including the
          provisions of Sections 6, 7, 9 and 14, which the parties expressly
          agree shall survive any expiration or termination hereof.

<PAGE>

     (e)  Except as expressly provided herein, nothing in this Agreement shall
          be construed to make any party hereto the representative or agent of
          any other party and no party shall so hold itself out, nor shall any
          party be liable for or bound by any act or omission of any other
          party.

     (f)  This Agreement in all respects shall be governed by and interpreted in
          accordance with the laws of the State of Delaware, U.S.A. without
          giving effect to principles of conflict of laws. Rodel and Nanophase
          hereby consent and submit to the jurisdiction of the state or federal
          courts in Delaware and agree that any litigation arising out of or
          relating to this Agreement shall be heard only in a state or federal
          court located in such state.

     (g)  Rodel and Nanophase each agree that during the term of this Agreement,
          and for eighteen months after the termination of the Agreement,
          neither party will directly or indirectly hire or engage any current
          or former employee or contractor of the other party, nor solicit or
          try to induce any current employee or contractor of the other party,
          to leave that party's employ or engagement.

     (h)  If any provision of this Agreement is held invalid by a court of
          competent jurisdiction, such invalidity shall not affect the other
          provisions of this Agreement.

     (i)  Any notice required or permitted to be given under this Agreement
          shall be made by personal delivery, courier, or by telecopy or first
          class mail to the party to whom delivery is intended at its address
          set forth above, or to such other address as either party shall notify
          to the other from time to time.
