JOINT VENTURE AGREEMENT

      California Energy Company, Inc. ("CE") and Kiewit Diversified Group
Inc. and Kiewit Construction Group Inc. (collectively one Party hereunder
and referred to as "Kiewit") each recognize the unique strengths of the
other Party and hereby form a Joint Venture to develop, construct, own and
operate power projects internationally as follows:

Strengths:              CE brings power project development expertise,
                        power project financing expertise, financial
                        wherewithal, power project operational expertise,
                        broad knowledge of the international power markets
                        and knowledge of the specific international power
                        project opportunities available.

                        Kiewit brings extensive power project construction
                        expertise, EPC turnkey contract capability, bonding
                        and performance and completion guarantee
                        capability, vendor relationships, infrastructure
                        development expertise, financial wherewithal, coal
                        mining expertise, and a broad knowledge of the
                        power markets internationally.


Power Projects:         Each Party has the right of first refusal to pursue
                        through this Joint Venture, all build, own and
                        operate or build, own, operate and transfer power
                        projects identified by the other Party or its
                        affiliates outside of the United States  except
                        those in which (i) the Joint Venture could not
                        acquire a controlling interest in the equity, (ii)
                        bid constraints would effectively prevent Kiewit's
                        or CE's participation, (iii)  participant,
                        contractor or partner constraints  would
                        effectively prevent Kiewit's or CE's participation,
                        or (iv) the power project location is in the
                        Caribbean, South America or that part of Central
                        America south of Mexico and such project is subject
                        to the right of Distral, S.A. to be developed with
                        CE under a CE/Distral Joint Venture Agreement
                        ("Distral Projects"); provided that, with respect
                        to Distral Projects, CE shall offer Kiewit the
                        opportunity to bid on civil construction or coal
                        supply or (if CE has the right to acquire more than
                        50% of the equity in such Distral Projects), to
                        participate with CE in the development funding and
                        equity, on a 50/50 basis, in each case pursuant to
                        the terms of CE's Joint Venture Agreement with
                        Distral, S.A.

                        Each Party shall notify the other Party of any
                        power project subject to the right of refusal as
                        soon as such Party believes that such project may
                        be subject to the right of refusal.  If the Joint
                        Venture does not promptly elect to pursue the
                        identified power project, either Party may pursue
                        the power project separately.

Development Manager 
& Development Costs:    The Parties shall share all project development
                        costs equally.  Development costs shall only be
                        incurred by, or at the direction of, CE as the
                        Joint Venture Development Manager and shall include
                        all development costs incurred after a power
                        project has been identified and offered to the
                        Joint Venture until a Party declines to participate
                        in such project or a Party or the Joint Venture or
                        a Project Entity abandons or transfers its interest
                        in a project or a Party is otherwise required to
                        discontinue its participation in a project. 
                        Development costs include out-of-pocket, third
                        party expenses incurred by the Parties in
                        furtherance of development of a power project as
                        well as the actual cost associated with employees
                        of the Parties who perform work to develop a power
                        project, in each case at the direction of the
                        Development Manager.

                        In no event shall the reimbursable costs for
                        employees be credited in excess of  the actual
                        fully burdened cost (as mutually agreed by the
                        Parties) for the actual time period involved by
                        such staff in Joint Venture development activities. 
                        It is anticipated that CE employees will perform a
                        majority of the development activities.  Kiewit
                        shall have the ability, however, to dedicate up to
                        one full-time equivalent employee to Joint Venture
                        activities, subject to agreement by the Parties as
                        to appropriate time commitment and cost
                        reimbursement arrangements with respect thereto.

                        Each Party shall submit bills (and provide all
                        reasonably requested supporting documentation) for
                        such development costs on a monthly basis and each
                        Party's share of such costs shall be payable within
                        30 days of submission of such bills . 
                        Semiannually, the Parties shall review and
                        reconcile any development costs incurred hereunder. 
                        Verified development costs shall be recovered at
                        project financial closing unless converted to
                        equity or subordinated debt in the projects.


Management 
Committee:              The Parties shall establish a management committee
                        to be comprised of two representatives of each of
                        CE and Kiewit, who shall act as agents of the
                        parties appointing them, to oversee and direct
                        Joint Venture  management level decisions. 
                        Management committee decisions shall be made by
                        majority vote.  In the event of a deadlock
                        regarding a particular project under development
                        which cannot be resolved by the good faith
                        negotiations of the Parties, (including the failure
                        to reach agreement on a turnkey construction
                        contract) either Party shall have the right by 15
                        days prior written notice to trigger a mandatory
                        discontinuance of both Parties with respect to the
                        particular project, in which case the
                        discontinuance provision below shall apply and CE
                        shall have the exclusive right to pursue such
                        project independently; provided however, that the
                        Parties shall negotiate mutually acceptable
                        deadlock resolution and buyout provisions, which
                        may vary from the foregoing provision as part of
                        the organizational documents for each Project
                        Entity.  Each management committee shall have
                        meetings not less often than quarterly.  The
                        Development Manager shall prepare, and the
                        management committee shall approve, and review as
                        necessary, annual budgets for Joint Venture
                        activities.  Day to day operational decisions
                        relating to the Joint Venture, as well as
                        individual projects and Project Entities shall be
                        made by the Development Manager.

Turnkey Construction:   Where the ability to select the turnkey contractor
                        is within the Joint Venture's control,  CE on
                        behalf of the Joint Venture  shall provide a
                        preferential opportunity to Kiewit or an affiliate
                        thereof to  negotiate a turnkey construction
                        contract with CE acting on behalf of the  Joint
                        Venture  for each such project.  Kiewit shall
                        provide completion and performance guarantees and
                        appropriate security (e.g. letter of credit,
                        guarantee, bond) reasonably required by project
                        finance lenders or other third party project
                        participants to secure performance of its
                        contractual obligations.  Prior to entering into
                        the turnkey contract, CE and Kiewit shall jointly
                        (i) agree upon the  technical/ systems/vendors to
                        be utilized, taking into account market conditions
                        and project financing requirements and (ii)  price
                        and select items of equipment whose value exceeds
                        $250,000.  CE and Kiewit shall jointly select the
                        engineering firm to be used by Kiewit for the
                        turnkey pricing and contract; provided that, to the
                        extent capable, The Ben Holt Co. will be given a
                        preferential opportunity to negotiate such an
                        engineering role in the turnkey contract for each
                        such project.

Project Entity:         After a power project has reached an appropriate
                        stage of development, CE shall endeavor to create a
                        Project Entity (e.g., corporation, limited
                        liability company, partnership), which shall be
                        reasonably acceptable to both Parties, to undertake
                        the financing of such power project.  The Project
                        Entity organizational documents shall reflect the
                        equity participation of the Parties and the fact
                        that CE shall act as the managing general partner
                        or in an analogous operating or managing role for
                        such Project Entity, subject to mutually acceptable
                        management or shareholder approval rights in favor
                        of Kiewit.  The provisions set forth in this Joint
                        Venture Agreement relating to the terms and
                        conditions of each Project Entity may be varied by
                        mutual agreement of the Parties; in the event of
                        any conflict between this Agreement and any
                        agreement relating to a Project Entity, the
                        agreement relating to the Project Entity shall
                        control.

Capital Contributions:  Unless otherwise negotiated by the Parties, CE and
                        Kiewit shall each provide 50% of the equity or
                        other sponsor-provided funding required from the
                        Parties for financing a power project developed by
                        the Joint Venture or a Project Entity.  If agreed
                        by the Parties and acceptable to project lenders,
                        equity contributions may be made in the form of
                        construction or engineering or other services
                        performed.  Development costs  may be considered
                        equity contributions of the Parties to the extent
                        agreed by the Parties and permitted by the
                        applicable project lender.  The Parties acknowledge
                        that any commitment by either Party to invest
                        equity will be conditioned upon obtaining
                        acceptable rates of return and other acceptable
                        provisions.

Profit/Loss/
Distributions:          All profits, losses and other distributions
                        (including fees and other similar compensation)
                        arising from Joint Venture or Project Entity
                        activities after repayment of development costs
                        (other than profits and losses arising under
                        separate construction and operation and maintenance
                        contracts)   shall be allocated 50/50 to CE and
                        Kiewit or otherwise in accordance with each Party's
                        equity contribution.

Operations & 
Maintenance:      CE shall serve as operator of all power projects
                  developed by the Joint Venture or a Project Entity under
                  an agreement acceptable to the Parties and project
                  lenders which provides reasonable oversight to the
                  Parties over operational expenses and activities.  CE
                  shall provide appropriate security (e.g. letter of
                  credit, guarantee, bond) reasonably required by lenders
                  or other third parties to secure performance of its
                  contractual obligations as operator.


Accounting:       As Development Manager, CE shall maintain, on behalf of
                  the  Joint Venture, records of development costs and such
                  other matters as are reasonably required in connection
                  with Joint Venture activities.  The records of the
                  Development Manager and each Project Entity shall be
                  accurate in all material respects and shall fairly
                  present the position and results of the Joint Venture and
                  each Project  Entity and shall be prepared on an accrual
                  basis in accordance with U.S.A. generally accepted
                  accounting principles consistently applied.


Discontinuance:   Except for binding obligations under executed contracts
                  including construction or operation and maintenance
                  agreements, with respect to any  project, either Party
                  may elect to discontinue its participation in the Joint
                  Venture or any project or Project Entity by delivering
                  written notice to the other 15 days in advance of its
                  discontinuance  provided that the discontinuing party
                  shall use all reasonable efforts to ensure that such
                  discontinuance shall not be made in a manner which would
                  disrupt any near term pending proposals and/or
                  negotiations such that the remaining Party is injured and
                  cannot continue with the proposal/negotiations.  Upon
                  delivery of such notice, the  Parties shall for no
                  additional consideration, execute appropriate assignment,
                  assumption, indemnity and release documents which
                  transfer, as of the date of the date of discontinuance,
                  to the remaining Party (or an affiliate thereof as
                  designated by such remaining Party) all obligations and
                  rights in the respective project or Project Entity or in
                  all power projects identified to the Joint Venture, but
                  not yet transferred to a Project Entity, whichever is
                  applicable.  Such  discontinuance by a Party shall be
                  immediately effective as an assignment of its interest in
                  any power project; however, the discontinuing Party shall
                  pay its share of development costs incurred  by the Joint
                  Venture or Project Entity on or before the date of
                  discontinuance, although  such expenses may come due
                  later.  The discontinuing Party shall be entitled to be
                  repaid its share of the development costs with respect to
                  any discontinued project out of the construction or
                  project financing therefor, but only after repayment to
                  the remaining party (and any new equity participants) of
                  all development costs incurred with respect to the
                  Project.

Right of First Refusal:

                  Notwithstanding any provision of this Agreement to the
                  contrary, either Party ("Selling Party") may sell or
                  transfer its interest in , any project or Project Entity
                  (but not the Joint Venture) to a third party, provided it
                  first notifies the other Party ("Offeree Party") of the
                  identity of the prospective purchaser, assignee or
                  transferee and sends to the Offeree Party a copy of the
                  written offer, and provided further that the Selling
                  Party shall first offer to sell all its interest in , any
                  project or Project Entity to the Offeree Party for the
                  same price, and on the same terms as those being offered
                  to the Selling Party.  The Offeree Party shall have 90

Compliance with Law:

                  In performing their respective activities hereunder, each
                  Party agrees to comply with all applicable United States,
                  and other applicable laws.  In this regard, each Party
                  agrees that neither it nor its employees,  agents or
                  subcontractors shall make any payment or give anything of
                  value to any government official to influence a

                  or a Project Entity in connection with the activities
                  performed hereunder.

Assignment:       Except for assignments to affiliates  and assignments to
                  lenders  and others (which each Party agrees to make as
                  reasonably required for project financing) and
                  assignments pursuant to the Right of First Refusal set
                  forth above, neither Party may sell, transfer, assign or
                  otherwise encumber any portion of its interest in the
                  Joint Venture any project, or any Project Entity without
                  the other Party's prior written consent.  For purposes of
                  this Agreement "Affiliate" of a Party shall mean a person
                  or entity controlling, controlled by or under common
                  control with the Party.

Nature of Joint Venture:

                  The Joint Venture shall not be considered, and this
                  Agreement shall not be considered to have formed, a
                  partnership or other legal entity.  Except for CE's
                  rights to incur project development expenses and act on
                  behalf of the Joint Venture as Development Manager within
                  the scope of this agreement, unless otherwise agreed,
                  neither Party shall be the agent or representative of, or
                  have the power to legally bind, the other Party in
                  connection with the activities of the Joint Venture, and
                  each Party shall be severally liable for any obligations
                  to third parties incurred in connection with Joint
                  Venture activities.

Term:             The initial term of the Joint Venture shall be 3 years;
                  but the term may be extended by mutual agreement of the
                  Parties.  The Joint Venture shall extend automatically 
                  successive terms of one year at the end of its term but
                  only for the sole purpose of considering identified power
                  projects not yet rejected or pursuing power projects for
                  which a Project Entity has not yet been formed.  The term
                  of each Project Entity shall be as set forth in its
                  organizational documents which shall establish a term at
                  least as long as is required to complete the development,
                  construction and operation of its respective power
                  project.  The term of the Right of First Refusal for any
                  identified project or Project Entity shall extend for a
                  term equal to the applicable Party's right to an equity
                  participation in such project or Project Entity. 
                  Notwithstanding the foregoing, the term of this Joint
                  Venture shall terminate upon the bankruptcy or
                  dissolution of either Party.


Cooperation:      Since this Joint Venture Agreement is expected to
                  continue for some time and both Parties recognize that
                  international power projects can present unique
                  challenges or require special arrangements, both Parties
                  will attempt in good faith to negotiate additional terms
                  or modifications to this Agreement in response to any
                  such unique circumstances which are encountered,
                  consistent with the intent of the Parties in forming this
                  Joint Venture.


      This Joint Venture Agreement has been duly authorized and executed by
each Party and is  intended to be a legally binding and enforceable
agreement under, and governed by, the laws of the state of  New York,
U.S.A.
