failing to contest the material allegations of a petition filed against it in
any proceeding seeking reorganization, arrangement, composition, readjustment,

            SECTION 6. SPECIAL MEMBER. Upon the occurrence of any event that
causes the Member to cease to be a member of the Company (other than upon an
assignment by the Member of all of its limited liability company interest in the
Company and the admission of the transferee pursuant to Section 7.01 of the
Agreement), each person acting as an Independent Manager pursuant to Section 5
hereof and Section 4.04 of the Agreement shall, without any action of any Person
and simultaneously with the Member ceasing to be a member of the

                                       -2-




Company, automatically be admitted to the Company as a Special Member and shall
continue the Company without dissolution. No Special Member may resign from the
Company or transfer its rights as a Special Member unless (i) a successor
Special Member has been admitted to the Company as a Special Member by executing
a counterpart to the Agreement, and (ii) such successor has also accepted its
appointment as Independent Manager, provided, however, the Special Members shall
automatically cease to be members of the Company upon the admission to the
Company of a substitute Member (who may be approved by the personal
representative of the last Member that ceased to be a member of the Company).
Each Special Member shall be a member of the Company that has no interest in the
profits, losses and capital of the Company and has no right to receive any
distributions of Company assets. Pursuant to Section 18-301(d) of the Act, a
Special Member shall not be required to make any capital contributions to the
Company and shall not receive a limited liability company interest in the
Company. A Special Member, in its capacity as Special Member, may not bind the
Company. Except as required by any mandatory provision of the Act, a Special
Member, in its capacity as a Special Member, shall have no right to vote on,
approve or otherwise consent to any action by, or matter relating to, the
Company, including the merger, consolidation or conversion of the Company. In
order to implement the admission to the Company of each Special Member, each
person acting as an Independent Manager pursuant to Section 5 hereof and Section
4.04 of the Agreement shall execute a counterpart to the Agreement. Prior to its
admission to the Company as a Special Member, each person acting as an
Independent Manager pursuant to Section 5 hereof and Section 4.04 of the
Agreement shall not be a member of the Company.

            SECTION 7. RIGHTS ON LIQUIDATION, DISSOLUTION OR WINDING UP.

            (a) The Company shall be dissolved, and its affairs shall be wound
up upon the first to occur of the following: (i) the termination of the legal
existence of the last remaining member of the Company or the occurrence of any
other event which terminates the continued membership of the last remaining
member of the Company in the Company unless the business of the Company is
continued in a manner permitted by the Agreement or the Act or (ii) the entry of
a decree of judicial dissolution under Section 18-802 of the Act.

            (b) In the event of dissolution, the Company shall conduct only such
activities as are necessary to wind up its affairs (including the sale of the
assets of the Company in an orderly manner), and the assets of the Company shall
be applied in the manner, and in the order of priority, set forth in Section
18-804 of the Act.

            (c) The Company shall terminate when (i) all of the assets of the
Company, after payment of or due provision for all debts, liabilities and
obligations of the Company shall have been distributed to the Member in the
manner provided for in the Agreement and (ii) this Certificate of Formation
shall have been canceled in the manner required by the Act.

            (d) Neither the sale of all or substantially all of the property or
business of the Company, nor the merger, conversion or consolidation of the
Company into or with another company or other entity, shall be deemed to be a
dissolution, liquidation or winding up, voluntary or involuntary, for the
purpose of this Section 7 and Section 7.03 of the Agreement.

                                      -3-



            (e) The commencement of a Bankruptcy, insolvency, receivership or
other similar proceeding by or against the Company shall not result in the
dissolution of the Company or in the cessation of the interest of the Member in
the Company.

            (f) Upon the occurrence of any event that causes the last remaining
member of the Company to cease to be a member of the Company, to the fullest
extent permitted by law, the personal representative of such member is hereby
authorized to, and shall, within 90 days after the occurrence of the event that
terminated the continued membership of such member in the Company, agree in
writing (i) to continue the Company and (ii) to the admission of the personal
representative or its nominee or designee, as the case may be, as a substitute
member of the Company, effective as of the occurrence of the event that
terminated the continued membership of the last remaining member of the Company
in the Company.

            (g) Notwithstanding any other provision of this Certificate of
Formation or of the Agreement, the Bankruptcy of the Member or any Special
Member shall not cause the Member or Special Member, respectively, to cease to
be a member of the Company, and upon the occurrence of such an event, the
business of the Company shall continue without dissolution.

            SECTION 8. NO BANKRUPTCY PETITION; NO DISSOLUTION.

            (a) To the fullest extent permitted by law, the Member, each Special
Member and each Manager hereby covenant and agree (or shall be deemed to have
hereby covenanted and agreed) that, prior to the date which is one year and one
day after the termination of the Indenture and the payment in full of every
Series of Transition Bonds and any other amounts owed under the Indenture,
including, without limitation, any amounts owed to third-party credit enhancers
or swap or hedge agreement counterparties with respect to any series of
Transition Bonds, it will not acquiesce, petition or otherwise invoke or cause
the Company to invoke the process of any court or Governmental Authority for the
purpose of commencing or sustaining a case against the Company under any federal
or state bankruptcy, insolvency or similar law or appointing a receiver,
liquidator, assignee, trustee, custodian, sequestrator or other similar official
of the Company or any substantial part of the property of the Company, or
ordering the winding up or liquidation of the affairs of the Company; provided,
however, that nothing in this Section 8 or Section 10.06 of the Agreement shall
constitute a waiver of any right to indemnification, reimbursement or other
payment from the Company pursuant to the Agreement. This Section 8 and Section
10.06 of the Agreement are not intended to apply to the filing of a voluntary
bankruptcy petition on behalf of the Company which is governed by Section 5(b)
of this Certificate of Formation and Section 4.04(b) of the Agreement.

            (b) To the fullest extent permitted by law, the Member, each Special
Member and each Manager hereby covenant and agree (or shall be deemed to have
hereby covenanted and agreed) that, until the termination of the Indenture and
the payment in full of any Series of the Transition Bonds and any other amounts
owed under the Indenture, including any amounts owed to third-party credit
enhancers or under any Swap Agreement or hedge agreement, the Member, such
Special Member and such Manager will not consent to, or make application for, or
institute or maintain any action for, the dissolution of the Company under
Section 18-801 or 18-802 of the Act or otherwise.

                                       -4-




            (c) In the event that the Member, any Special Member or any Manager
takes action in violation of this Section 8 or Section 10.06 of the Agreement,
the Company agrees that it shall file an answer with the court or otherwise
properly contest the taking of such action and raise the defense that the
Member, the Special Member or Manager, as the case may be, has agreed in writing
not to take such action and should be estopped and precluded therefrom and such
other defenses, if any, as its counsel advises that it may assert.

            (d) The provisions of this Section 8 and Section 10.06 of the
Agreement shall survive the termination of the Agreement and the resignation,
withdrawal or removal of the Member, any Special Member or any Manager. Nothing
contained herein or in the Agreement shall preclude participation by the Member,
any Special Member or a Manager in assertion or defense of its claims in any
such proceeding involving the Company.

            SECTION 9. CONFLICT. In the event of any conflict or inconsistency
between the provisions of this Certificate of Formation and of the Agreement, to
the fullest extent permitted by law, the provisions of this Certificate of
Formation shall govern.

            IN WITNESS WHEREOF, the undersigned has executed and delivered this
Amended and Restated Certificate of Formation of CenterPoint Energy Transition
Bond Company II, LLC this 14th day of December, 2005.
