1999 (this "Supplemental Indenture"), is by and between SALTON SEA FUNDING
CORPORATION, a Delaware corporation (the "Funding Corporation"), and CHASE
MANHATTAN BANK AND TRUST COMPANY, NATIONAL ASSOCIATION, a banking association

(together with its successors in such capacity, the "Trustee").

                              W I T N E S S E T H:

                  WHEREAS, the Funding Corporation and the Trustee have entered
into that certain Trust Indenture dated as of July 21, 1995 (as amended,
modified or supplemented by that certain First Supplemental Indenture dated as

20, 1996, that certain Third Supplemental Indenture dated as of July 29, 1996,
that certain Fourth Supplemental Indenture dated as of October 13, 1998 and this
Supplemental Indenture, and as subsequently amended, modified or supplemented,
the "Indenture") by and between the Funding Corporation and the Trustee;

                  WHEREAS, the Funding Corporation has been formed for the sole
purpose of issuing securities under the Indenture, as principal and as agent for
the Guarantors (as defined in the Indenture), and for entering into those
transactions incidental thereto;

                  WHEREAS, (i) the Salton Sea Guarantors have guaranteed to the
Trustee the payment of principal, premium (if any), interest and other amounts
due from the Funding Corporation to the Secured Parties, and (ii) the
Partnership Guarantors and the Royalty Guarantor have guaranteed to the Trustee
the payment of principal, premium (if any), interest and other amounts due from
the Funding Corporation to the Secured Parties up to an amount equal to, with
respect to the Partnership Guarantors and the Royalty Guarantor, such
Guarantors' Available Cash Flow;

                  WHEREAS, Funding Corporation is a wholly-owned subsidiary of
Magma and Magma is a wholly-owned subsidiary of CalEnergy. After the execution
of this Supplemental Indenture, CalEnergy intends to divest 50% of its indirect
interests in the Funding Corporation, and 50% of its interests in Magma and,
except as provided below, the Guarantors (the "Divestiture"). The Divestiture is
intended to permit the geothermal power generating facilities located in
Imperial Valley, California, which are owned by indirect subsidiaries of
CalEnergy (the "Power Projects"), to maintain their status as Qualifying
Facilities following CalEnergy's acquisition of MidAmerican Energy Holdings
Company, an Iowa corporation ("MidAmerican"). The Funding Corporation, pursuant
to that certain Consent Solicitation dated as of February ____, 1999 (the
"Consent Solicitation"), has sought and received the consent of the Holders of
not less than 51% in the aggregate principal amount of the Securities then
Outstanding (the "Requisite Consents"), to amend or waive certain restrictive
covenants and other provisions in the Indenture, thereby removing any Events of
Default under the Indenture that would result in connection with CalEnergy's
consummation of the Divestiture;



                  WHEREAS, prior to the consummation of the Divestiture, each of
three Guarantors, Fish Lake, the Royalty Guarantor and BN/Geothermal propose to
be converted from a corporation to a Delaware limited liability company (the
"LLC Restructuring"). The LLC Restructuring will be implemented through the
merger of each of the aforementioned corporate Guarantors into newly-formed
limited liability company Guarantors, Fish Lake Power LLC, Salton Sea Royalty
LLC and VPC Geothermal LLC, which are owned by the same parent companies in the
same proportions as such aforementioned corporate Guarantors. The Funding
Corporation, pursuant to the Consent Solicitation, has sought and received the
Requisite Consents of the Holders to waive certain covenants in the Indenture
and the Credit Agreements, thereby removing any Events of Default under the
Indenture and the Credit Agreements that would result from the consummation of
the LLC Restructuring;

                  WHEREAS, the Zinc Project is not a Power Project and is
currently owned by Minerals LLC. SSMC and Magma each own a 50% membership
interest in Minerals LLC. CalEnergy intends to retain 100% of its interest in
the Zinc Project, which will be accomplished, prior to the consummation of the
Divestiture, by: (i) a contribution by Magma to SSMC of Magma's membership
interests in Minerals LLC, (ii) a dividend to CalEnergy of Magma's membership
interests in Minerals LLC and Magma's stock in SSMC, and (iii) if applicable, a
dividend to CalEnergy via Magma of the Funding Corporation's stock in SSMC
(collectively, the "Zinc Project Restructuring"). This will result in CalEnergy
owning 100% of the stock of SSMC and SSMC owning 100% of the membership
interests in Minerals LLC. The Funding Corporation, pursuant to the Consent
Solicitation, has sought and received the Requisite Consents of the Holders to
waive certain covenants in the Indenture, thereby removing any Events of Default
under the Indenture that would result from the consummation of the Zinc Project
Restructuring;

Geothermal LLC wish to confirm their assumption of the obligations of Fish Lake,
the Royalty Guarantor and BN/Geothermal, respectively;

                  WHEREAS, prior to the consummation of the Divestiture, Funding
Corporation desires to increase the assets securing the Guarantors' obligations
under the Credit Agreements and Funding Corporation's obligations under the
Indenture by adding two additional Guarantors: CESS and SSMC;

                  WHEREAS, prior to the consummation of the Divestiture, Magma
intends to contribute to CESS Magma's membership interests in Power LLC and
Turbo LLC. This will result in CESS owning 100% of the membership interests of
Power LLC and Turbo LLC;

                  WHEREAS, prior to the consummation of the Divestiture,
CalEnergy desires to increase the assets securing the Partnership Guarantors'
obligations under the Partnership Credit Agreement by entering into that certain
guarantee (the "CalEnergy Guarantee") pursuant to which CalEnergy shall
guarantee (subject to its right to terminate or amend such guarantee) certain of
the regularly scheduled payment obligations of the Partnership Guarantors to
Funding Corporation under that certain promissory note dated October 13, 1998 in

Corporation pursuant to the Partnership Credit Agreement in connection with the
sale of the Series F Securities;

thereof may be amended or supplemented from time to time by the Funding
Corporation and the Trustee, without the consent of the Holders, pursuant to a

approved by the Requisite Consents of the Holders, for the purpose of adding any
mutually agreeable provisions to or changing in any manner or eliminating any of
the provisions of, the Indenture;

time to time by the Funding Corporation and the Trustee, without the consent of
the Holders, for one or more of the purposes set forth therein, which purposes
include, without limitation, to increase the assets securing the Guarantors'
obligations under the Credit Agreements or the Project Notes and to cure any

                  WHEREAS, Section 8.3 of the Indenture provides that the terms
of the Credit Agreements and the Project Notes may be amended or supplemented
from time to time and the Funding Corporation and the Trustee may grant a waiver
or consent thereunder (subject to certain limitations which are not applicable
here) with the Requisite Consents of the Holders;

                  WHEREAS, the Funding Corporation and the Trustee desire to
amend Sections 5.19 and 8.3 of the Indenture to add additional covenants of the
Funding Corporation and to confer upon the Holders additional rights with
