6.   (a)  As used in this Certificate of Incorporation, (i) a "Person" is an
          individual, partnership, corporation (including a business trust),
          joint stock company, trust, limited liability company, unincorporated
          association, joint venture, government (including any agency or
          subdivision thereof) or any other entity; (ii) an "Affiliate" of a
          Person is a Person that directly or indirectly through one or more
          intermediaries, controls or is controlled by, or is under common
          control with, the Person specified; and (iii) an "Associate," when
          used to indicate a relationship with any Person, is (A) a corporation
          or organization of which such Person is an officer, director or
          partner or is, directly or indirectly, the beneficial owner of ten

          capacity, and (C) any relative or spouse of such Person, or any
          relative of such spouse, who has the same home as such Person.

     (b)  The business and affairs of the Corporation shall be managed by and
          under the direction of the Board of Directors. At any given time, the
          Corporation will have at least one member of the Corporation's Board
          of Directors (herein referred to as the "Independent Director") and at
          least one officer (herein referred to as the "Independent Officer"),
          each of whom shall be an individual who is not (and is not an
          Associate of), and for a twelve-month period prior to election or
          appointment, as the case may be, has not been a direct, indirect or
          beneficial holder of two percent or more of any class of equity
          securities, director, officer or employee of any Affiliate of the
          Corporation. The same individual may serve both as an Independent
          Director and an Independent Officer.

     (c)  No Independent Director serving pursuant to the requirements of this
          Paragraph 6 shall, with regard to any matter described in Paragraph 8,
          owe a fiduciary duty or other obligation to the stockholders (except
          as may specifically be required by the statutory law of any applicable
          jurisdiction); instead, such Independent Director's fiduciary duty and
          other obligations with regard to any matter described in Paragraph 8
          shall be owed to the Corporation including, without limitation, the
          Corporation's creditors. Every stockholder of the Corporation shall be
          deemed to have consented to the foregoing by virtue of such
          stockholder's purchase of shares of capital stock of the Corporation,
          and no further act or deed of any stockholder shall be required to
          evidence such consent. In addition, no Independent Director may be
          removed unless his or her successor has been duly elected.

     (d)  The Corporation's Board of Directors is authorized to make, alter or
          repeal the by-laws of the corporation. Election of directors need not
          be by written ballot.

7.   A director of the Corporation shall not be personally liable to the
     Corporation or its stockholders for monetary damages for any breach of
     fiduciary duty as a director, except for liability (i) for any breach by
     the director of his duty of loyalty to the Corporation or its stockholders,
     (ii) for acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law, (iii) under Section 174 of the
     General Corporation Law of the State of Delaware or (iv) for any
     transaction from which the director derived an improper personal benefit.

     No repeal, modification or amendment of, or adoption of any provision
     inconsistent with this Paragraph 7 nor, to the fullest extent permitted by
     law, any modification of law shall adversely affect any right or protection
     of a director of the corporation existing at the time of such repeal,
     amendment, adoption or modification or affect the liability of any director
     of the corporation for any action taken or any omission that occurred prior
     to the time of such repeal, amendment, adoption or modification.

     If the General Corporation Law of the State of Delaware shall be amended
     after this Certificate of Incorporation is filed with the Secretary of
     State of Delaware to authorize corporate action further eliminating or
     limiting the liability of directors, then a director of the corporation, in
     addition to the circumstances in which he is not liable immediately prior
     to such amendment, shall be free of liability to the fullest extent
     permitted by the General Corporation Law of Delaware, as so amended.

8.   The Corporation shall not, without the affirmative vote of each member of
     the Corporation's Board of Directors, including the affirmative vote of the

          custodian, receiver, trustee or other similar official for it or for a
          substantial part of its property, commence any proceeding under any
          bankruptcy, reorganization, arrangement, readjustment of debt,

          acquiesce in the filing of any such petition, application, proceeding
          or appointment of or taking possession by the custodian, receiver,
          liquidator, assignee, trustee, sequestrator (or other similar
          official) of the Corporation or any substantial part of its property,
          admit its inability to pay its debts generally as they become due, or
          declare or effect a moratorium on its debt or authorize any of the
          foregoing to be done or taken on behalf of the Corporation;

     (b)  be a party to any merger or consolidation or sell, transfer, assign,
          convey or lease any substantial part of the assets of the Corporation,

          surviving the consolidation or merger or which acquires the properties
          or assets of the Corporation is a corporation organized and existing
          under the laws of the United States, any state thereof or the District
          of Columbia, expressly assumes the due and punctual payment of, and

          certificate of incorporation containing provisions substantially
          identical to the provisions of Paragraph 3, Paragraph 6, Paragraph 8,
          Paragraph 9 and Paragraph 10, and, immediately after giving effect to
          the proposed merger, consolidation or transfer, no default or event of
          default under any obligation of the Corporation would occur and be
          continuing; or

     (c)  dissolve or liquidate, in whole or in part; provided that if there is
          not one Independent Director then in office and acting, a vote upon
          any matter set forth in this Paragraph 8 shall not be taken unless and
          until one Independent Director shall have been duly elected.

9.   Without the affirmative vote of each member of the Corporation's Board of
     Directors, including the affirmative vote of the Independent Director, the
     Corporation shall not amend Paragraph 3, Paragraph 6, Paragraph 8,
     Paragraph 10, and this Paragraph 9 (together, the "Independent Director
     Provisions") of this Certificate of Incorporation or any By-laws of the
     Corporation related to the Independent Director Provisions; provided that
     if there is not one Independent Director then in office, no vote upon any
     matter set forth in this Paragraph 9 shall be taken unless and until one
     Independent Director shall have been duly elected.

10.  The Corporation shall take all reasonable steps to continue its identity as
     a separate legal entity and to make it apparent to third Persons that the
     Corporation is an entity with assets and liabilities distinct from those of
     Morgan Stanley Dean Witter & Co. and any other Person, and that the
     Corporation is not a division of Morgan Stanley Dean Witter & Co. or any
     other Person. Without limiting the generality of the foregoing, the
     Corporation shall take the following actions:

     (a)  The Corporation will compensate each of its employees, consultants and
          agents from the Corporation's own funds for services provided to the
          Corporation, except as provided in the Services Agreement between the
          Corporation and Morgan Stanley & Co. Incorporated (the "Services
          Agreements"). Morgan Stanley Dean Witter and its subsidiaries and
          affiliates may act as agent of the Corporation only through express
          agencies created by arms-length agreements and any such agencies will
          be conducted only on a fully disclosed basis and for fair
          compensation. Accountants and attorneys will be fairly compensated by
          the Corporation for their fees and other charges as agreed to by the
          Corporation and such accountants or attorneys (as applicable).

     (b)  The Corporation shall pay from its own assets all obligations of any
          kind incurred by the Corporation, recognizing, however, that certain
          organizational expenses of the Corporation have been or shall be paid
          by Morgan Stanley & Co. Incorporated in such capacity.

     (c)  The Corporation shall take all appropriate action necessary to
          maintain its existence in good standing under the laws of the State of
          Delaware. The Corporation shall conduct its own business in its own
          name and shall observe all customary formalities, including holding
          regular meetings of its Board of Directors and its stockholders and
          maintenance of current minute books. Regular meetings of the Board of
          Directors shall be held at least annually.

     (d)  The Corporation will allocate fairly and reasonably any overhead for
          shared office space.

     (e)  The Corporation will maintain financial reports, corporate records and
          books of account separate from those of any other person, and
          stationery, invoices, and business forms that are separate and
          distinct from those of any other Person.

     (f)  Any financial statements of any Affiliate of the Corporation which are
          consolidated to include the Corporation will contain detailed notes
          clearly stating that (i) all of the Corporation's assets are owned by
          the Corporation and (ii) the Corporation is a separate corporate
          entity with its own separate creditors which will be entitled to be
          satisfied out of the Corporation's assets prior to any asset of the
          Corporation becoming available to the holder of any stock of the
          Corporation.

     (g)  The Corporation shall not commingle its assets with those of any of
          its Affiliates. The Corporation's assets will be separately identified
          and segregated. All of the Corporation's assets shall at all times be
          held by or on behalf of the Corporation, and, if held on behalf of the
          Corporation by another entity, shall be kept identifiable (in
          accordance with customary usages) as assets owned by the Corporation.
          The Corporation will strictly observe corporate formalities in its
          dealings with each of its Affiliates. The Corporation shall not
          maintain joint bank accounts or other depository accounts to which any
          of its Affiliates has independent access.

     (h)  The Corporation shall not, directly or indirectly, be named and shall
          not enter into an agreement to be named as a direct or contingent
          beneficiary or loss payee on any insurance policy covering the
          property of any of its Affiliates.

     (i)  The Corporation will maintain arm's length relationships with each of
          its Affiliates. All business transactions entered into by the
          Corporation with any of its Affiliates shall be on terms that are not
          more or less favorable to the Corporation than the terms and
          conditions that could have been obtained, under similar circumstances,
          from unaffiliated persons. In addition, except for transactions under
          the Services Agreement, purchases of Debt Securities or Credit Support
          by the Corporation for the purposes of the formation of Trusts and
          issuance of Units pursuant to the Program Documents, sales of Units by
          the Corporation to or through its broker-dealer Affiliates pursuant to
          a Distribution Agreement, and other transactions contemplated by the
          Program Documents in the ordinary course of the Corporation's
          business, all business transactions entered into by the Corporation
          with any of its Affiliates shall be approved by the unanimous written
          consent of the Board of Directors. The Corporation will pay its own
          liabilities out of its own funds. Neither the Corporation nor any of
          its Affiliates will guarantee the debts of the other, will pledge, or
          grant a security interest in or lien upon, its assets for the benefit
          of the other, or will be or will hold itself out to be responsible for
          the debts of the other or the decisions or actions respecting the
          daily business and affairs of the other.

     (j)  The annual financial statements of the Corporation will disclose, in
          accordance with generally accepted accounting principles, any
          transactions between the Corporation and any of its Affiliates.

     (k)  The Corporation will retain as its auditors a nationally recognized
          firm of certified public accountants.

purpose of forming a corporation pursuant to the General Corporation Law of
Delaware, do make this Certificate, declaring and certifying that this is my act
