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 percent or more of any class
           of equity securities, (B) any trust or other estate in
           which such Person serves as trustee or in a similar
           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.

      the Corporation's Board of Directors, including the affirmative vote of

           a petition in bankruptcy, petition or apply to any
           tribunal for the appointment of a 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, dissolution or
           liquidation law or statute or similar law or statute
           of any jurisdiction, whether now or hereinafter in
           effect, consent or acquiesce in the filing of any such
           petition, application, proceeding or appointment of or
           taking possession by the custodian, receiver,

           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

           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, unless the entity (if
           other than the Corporation) formed under or 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 all obligations of the Corporation in
           connection with, indebtedness of the Corporation
           permitted by this Certificate of Incorporation, has a
           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.
