         A. The Company's existence shall commence upon the acceptance of these
Articles of Organization by the Secretary of State of Iowa for filing and shall
be perpetual, unless sooner dissolved pursuant to the terms of its operating
agreement, or as otherwise provided by law.

Company.

                                      -4-


                                   ARTICLE VI
                           WRITTEN OPERATING AGREEMENT

         Any operating agreement entered into by the member or members of the
Company, and any amendments or restatements thereof, shall be in writing. No
oral agreement among any of the members or managers of the Company shall be
deemed or construed to constitute any portion of, or otherwise affect the
interpretation of, any written operating agreement of the Company, as amended
and in existence from time to time.


                                   ARTICLE VII
                                BOARD OF MANAGERS

         A. The business and affairs of the Company shall be governed by a board
of managers, which shall include at all times at least one individual who is an
Independent Manager (as defined below). The rights and powers exercised by the
Independent Manager in the management of the business and affairs of the Company
may not be delegated. The actions of a member or any other person acting in any
capacity other than as a manager of the Company shall not bind the Company.

         B. An "Independent Manager" shall be an individual who is not, at the
time of his or her appointment or any time thereafter, and was not at any time
during the preceding five years: (i) a direct or indirect legal or beneficial
owner of any shares of the capital stock or membership interests, as applicable,
of the Company, CalEnergy or any of CalEnergy's subsidiaries, except that an
Independent Manager may own shares of the capital stock or membership interests,
as applicable, of CalEnergy or any of its direct or indirect subsidiaries having
a value, at all times in which such person is the Independent Manager, not
exceeding 1% of such person's assets, (ii) a director, officer, employee,
manager, trustee, partner, affiliate, family member, major supplier, major
contractor or major creditor of the Company or of any of the Company's
affiliates (except solely by virtue of serving as an Independent Manager of the
Company) or (iii) a person who, directly or indirectly, controls (except solely
by virtue of serving as an Independent Manager of the Company) (A) the Company,
(B) any affiliate of the Company or (C) any person or entity set forth in clause
(ii) of this section (B). The term "major supplier" means a person or entity to
which the Company or its affiliates, as applicable, has outstanding indebtedness
for borrowed money in a sum sufficiently large as would reasonably be expected
to influence the judgment of the proposed Independent Manager adversely to the
interests of the Company and its creditors. The term "major contractor" means a
person or entity that has contracts with the Company in a sum sufficiently large
as would reasonably be expected to influence the judgment of the proposed
Independent Manager adversely to the interests of the Company and its creditors.
The term "major creditor" means a person or entity to which the Company or its
affiliates, as applicable, has outstanding indebtedness for borrowed money in a
sum sufficiently large as would reasonably be expected to influence the judgment
of the proposed Independent Manager adversely to the interests of the

                                      -5-


Company or its other creditors. The term "family member" means any child,
stepchild, grandchild, parent, grandparent, spouse, sibling, niece, nephew,
mother-in-law, father in-law, son-in-law, daughter-in-law, brother-in-law or
sister-in-law, and shall include adoptive relationships. The term "affiliate"
means any person or entity controlling, controlled by, or under common control
with the Company, whether by virtue of the holding of voting securities, the
election of members of the Board of Managers or another governing body or
otherwise.

         C. In the event of the insolvency of the Company and with regard to any
action requiring the affirmative vote of the Independent Manager, the Managers
will owe their fiduciary duties to the Company and its creditors.


                                  ARTICLE VIII
                             LIMITATION OF LIABILITY

         A. A manager of the Company shall not be personally liable to the
Company or its members for monetary damages for breach of fiduciary duty as a
manager, except for liability:

              (i)   for any breach of the manager's duty of loyalty to the
                    Company or its members; or

              (ii)  for acts or omissions not in good faith or which involve
                    intentional misconduct or a knowing violation of law; or

              (iii) for any transaction from which the manager derives an
                    improper personal benefit or a wrongful distribution in
                    violation of Section 490A.807 of the Act.

         B. If, after the date these Articles of Organization are filed with the
Iowa Secretary of State, the Act is amended to authorize action further
eliminating or limiting the personal liability of managers, then the liability
of a manager of the Company shall be deemed eliminated or limited to the fullest
extent permitted by the Act, as so amended. Any repeal or modification of
Section A or this Section B of this Article VIII, by the members of the Company
shall be prospective only and shall not adversely affect any right or protection
of a manager of the Company existing at the time of such repeal or modification.


                                   ARTICLE IX
                                 INDEMNIFICATION

         A. Each person who was or is a party or is threatened to be made a
party to or is involved in any action, suit or proceeding, whether civil,
criminal, administrative, investigative or arbitration and whether formal or
informal ("proceeding"), by reason of the fact that he or she, or a person of
whom he or she is the legal representative, is or was a manager, officer or
employee, of the Company or is or was serving at the request of the Company as a
director, manager, officer or employee of another corporation or of a
partnership, limited liability

                                      -6-


company, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity while serving as a manager, officer or
employee or in any other capacity while serving as a manager, officer or
employee, shall be indemnified and held harmless by the Company to the fullest
extent authorized by the Act, as the same exists or may hereafter be amended
(but, in the case of any such amendment, only to the extent that such amendment
permits the Company to provide broader indemnification rights than the Act
permitted the Company to provide prior to such amendment), against all
reasonable expenses, liability and loss (including without limitation attorneys'
fees, all costs, judgments, fines, Employee Retirement Income Security Act
excise taxes or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by such person in connection therewith. Such
right shall be a contract right and shall include the right to be paid by the
Company expenses incurred in defending any such proceeding in advance of its
final disposition; provided, however, that the payment of such expenses incurred
by a manager, officer or employee in his or her capacity as a manager, officer
or employee (and not in any other capacity in which service was or is rendered
by such person while a manager, officer or employee including, without
limitation, service to an employee benefit plan) in advance of the final
disposition of such proceeding, shall be made only upon delivery to the Company
of (i) a written undertaking, by or on behalf of such manager, officer or
employee, to repay all amounts so advanced if it should be determined ultimately
that such manager, officer or employee is not entitled to be indemnified under
this Article IX or otherwise, or (ii) a written affirmation by or on behalf of
such manager, officer or employee that, in such person's good faith belief, such
person has met the standards of conduct set forth in the Act.

         B. If a claim under Section A is not paid in full by the Company within
thirty (30) days after a written claim has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant shall be entitled to be paid also the expenses of prosecuting such
claim. It shall be a defense to any such action that the claimant has not met
the standards of conduct which make it permissible under the Act for the Company
to indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Company. The failure of the Company (including its Board
of Managers, independent legal counsel or its members) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the Act, shall not be a defense to
the action or create a presumption that the claimant had not met the applicable
standard of conduct.

         C. Indemnification provided hereunder shall, in the case of the death
of the person entitled to indemnification, inure to the benefit of such person's
heirs, executors or other lawful representatives. The invalidity or
unenforceability of any provision of this Article IX shall not affect the
validity or enforceability of any other provision of this Article IX.

         D. The rights conferred on any person by this Article IX shall not be
exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the Articles of Organization, operating
agreement, agreement, vote of members or disinterested managers or otherwise.

                                      -7-


         E. The Company may maintain insurance, at its expense, to protect
itself and any such manager, officer, employee or agent of the Company or
another corporation, partnership, limited liability company, joint venture,
trust or other enterprise against any such expense, liability or loss, whether
or not the Company would have the power to indemnify such person against such
expense, liability or loss under the Act.


                                    ARTICLE X
                                   AMENDMENTS

         Subject to the last sentence of Section B of Article VIII, these
Articles may be amended, repealed, changed or modified in accordance with the
provisions of the Act and the Company's operating agreement. The foregoing
notwithstanding, as long as any of the Securities are outstanding, (i) subject
to clause (ii) below, the provisions of Article IV, V and Article VII of these
Articles of Organization shall not be changed, amended, repealed or effected in
any way unless the Company complies with the provisions of section (B)(x) of
Article IV and (ii) paragraphs (B)(i), (ii) and (iv) of Article IV may be
amended or modified if, prior to the effectiveness of such amendment or
modification, the Company obtains written confirmation from each of Standard &
Poor's Ratings Group, Moody's Investors Service, Inc. and Duff & Phelps Credit
Rating Co. (or, if any such agency ceases to rate the Securities for any reason
outside the control of the Company, any other "nationally recognized statistical
rating organization" within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the
Securities Exchange Act of 1934, selected by the Company as a replacement rating
agency; each a "Rating Agency"), that such amendment or modification will not
result in lowering by any Rating Agency of the credit rating assigned to the
Securities by such Rating Agency as of the date of such amendment or
modification.

                                      -8-
