Sponsor and the Trustees hereby agree as follows:

          1.   The trust created hereby shall be known as "NWPS Capital

extent provided herein, may conduct the business of the Trust, make and execute
contracts, and sue and be sued.

          2.   The Sponsor hereby assigns, transfers, conveys and sets over to
the Trustees the sum of $10.  The Trustees hereby acknowledge receipt of such
amount in trust from the Sponsor, which amount shall constitute the initial
trust estate.  The Trustees hereby declare that they will hold the trust estate
in trust for the benefit of the Sponsor.  It is the intention of the parties
hereto that the Trust created hereby constitute a business trust under Chapter
38 of Title 12 of the Delaware Code, 12 DEL. C. Section 3801 ET SEQ. (the

instrument of the Trust.  The Trustees are hereby authorized and directed to
execute and file a certificate of trust with the Delaware Secretary of State in
the form attached hereto.

          3.   The Sponsor and the Trustees will enter into an amended and
restated Declaration of Trust, satisfactory to each such party and substantially
in the form included as an exhibit to the 1933 Act Registration Statement (as
defined below), to provide for the contemplated operation of the Trust created
hereby and the issuance of the Preferred Securities and Common Securities
referred to therein.  Prior to the execution and delivery of such amended and
restated Declaration of Trust, the Trustees shall not have any duty or
obligation hereunder or with respect of the trust estate, except as otherwise
required by applicable law or as may be necessary to obtain prior to such
execution and delivery any licenses, consents or approvals required by
applicable law or otherwise.

          4.   The Sponsor and the Trustees hereby authorize and direct the
Sponsor, as the sponsor of the Trust, (i) to file with the Securities and
Exchange Commission (the "Commission") and execute, in each case on behalf of
the Trust (a) a Registration Statement on Form S-3 (the "1933 Act Registration
Statement"), including all pre-effective and post-effective amendments thereto,
relating to the registration of the Preferred Securities of the Trust under the
Securities Act of 1933, as amended, and (b) a Registration Statement on Form 8-A
(the "1934 Act Registration Statement"), including all pre-effective and post-
effective amendments thereto, relating to the registration of the Preferred
Securities of the Trust under Section 12(b) of the Securities Exchange Act of
1934, as amended; (ii) to file



with the New York Stock Exchange and execute on behalf of the Trust a listing
application and all other applications, statements, certificates, agreements and
other instruments as shall be necessary or desirable to cause the Preferred

execute on behalf of the Trust such applications, reports, surety bonds,
irrevocable consents, appointments of attorney for service of process and other
papers and documents as shall be necessary or desirable to register the
Preferred Securities under the securities or "Blue Sky" laws of such
jurisdictions as the Sponsor, on behalf of the Trust, may deem necessary or
desirable and (iv) to execute on behalf of the Trust that certain Underwriting
Agreement among the Trust, the Sponsor and Morgan Stanley & Co.,  Incorporated,
substantially in the form included as an exhibit to the 1933 Act Registration
Statement.  In the event that any filing referred to in clauses (i)-(iii) above
is required by the rules and regulations of the Commission, the New York Stock
Exchange or state securities or blue sky laws, to be executed on behalf of the
Trust by the Trustees, Merle D. Lewis and Richard R. Hylland, in their
capacities as Trustees of the Trust, are hereby authorized and directed to join
in any such filing and to execute on behalf of the Trust any and all of the
foregoing, it being understood that Wilmington Trust Company, in its capacity as
Trustee of the Trust, shall not be required to join in any such filing or
execute on behalf of the Trust any such document unless required by the rules
and regulations of the Commission, the New York Stock Exchange or state
securities or blue sky laws.  In connection with all of the foregoing, the
Sponsor and each Trustee, solely in its capacity as Trustee of the Trust, hereby
constitutes and appoints Merle D. Lewis, as his or its, as the case may be, true
and lawful attorney-in-fact, and agent, with full power of substitution and
resubstitution, for the Sponsor or such Trustee or in the Sponsor's or such
Trustee's name, place and stead, in any and all capacities, to sign any and all
amendments, including post-effective amendments, to the 1933 Act Registration
Statement and the 1934 Act Registration Statement, and to file the same, with
all exhibits thereto, and other documents in connection therewith, with the
Commission, granting unto said attorney-in-fact and agent full power and
authority to do and perform each and every act and thing requisite and necessary
to be done in connection therewith, as fully to all intents and purposes as the
Sponsor or such Trustee might or could do in person, hereby ratifying and
confirming all that said attorney-in-fact and agent, or his substitute or
substitutes, shall do or cause to be done by virtue hereof.

          5.   This Declaration of Trust may be executed in one or more

decrease the number of Trustees; provided, however, that the number of Trustees
shall in no event be less than three (3); and provided, further that to the
extent required by the Business Trust Act, one Trustee shall either be a natural
person who is a resident of the State of Delaware or, if not a natural person,
an entity which has its principal place of business in the State of Delaware.
Subject to the foregoing, the Sponsor is entitled to appoint or remove without
cause any Trustee at any time.  The Trustees may resign upon thirty (30) days
prior notice to the Sponsor.

liable, responsible or accountable, in damages or otherwise, to the Trust or any
other Indemnified 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

Person's gross negligence or wilful misconduct with respect to such acts or
omissions.

          9.   To the fullest extent permitted by applicable law, the Sponsor
shall indemnify and hold harmless each Indemnified Person from and against any
loss, damage or claim incurred by such Indemnified Person by reason of any act

to be within the scope of the authority conferred on such Indemnified Person by
this Declaration of Trust, except that no Indemnified Person shall be entitled
to be indemnified in respect of any loss, damage or claim incurred by such
Indemnified Person by reason of gross negligence or wilful misconduct with

(including legal fees) incurred by an Indemnified Person in defending any claim,
demand, action, suit or proceeding shall, from time to time, be advanced by the
Sponsor prior to the final disposition of such claim, demand, action, suit or

Indemnified Person is not entitled to be indemnified as authorized in Section 9.

others, similar or dissimilar to the business of the Trust, and the Trust, the
Sponsor and the other Trustees shall have no rights by virtue of this
Declaration of Trust in and to such independent ventures or the income or
profits derived therefrom, and the pursuit of any such venture,

                                        3


even if competitive with the business of the Trust, shall not be deemed wrongful
or improper.  Wilmington Trust Company shall not 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 Wilmington Trust Company 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.  Wilmington Trust Company may engage
or be interested in any financial or other transactions with the Sponsor or any
affiliate of the Sponsor, or may act on any committee or body of holders of
securities or other obligations of the Sponsor or its affiliates.

accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).
