__________________________________ )

    Plaintiff, by his attorneys, for his class action complaint against
defendants, alleges upon personal knowledge with respect to his own acts, and
upon information and belief based upon, inter alia, the investigation of counsel
as to all other allegations herein, as follows:


 
                             NATURE OF THE ACTION
                             --------------------

    1. This is a stockholders' class action lawsuit brought on behalf of the
public stockholders of Magma Power Co. ("Magma Power" or the "Company") who have
been, and continue to be, deprived of the opportunity to realize fully the 
benefits of their investment in Magma Power. The individual defendants have 
wrongfully refused to properly consider a bona fide offer for the Company from 
California Energy Co. ("California Energy") and, therefore, have wrongfully 
entrenched themselves in their positions of control. The individual defendants' 
actions were, and are, unreasonable in relation to any perceived threat posed by
California Energy's offer. The individual defendants are using their fiduciary 
positions of control over Magma Power to thwart others in their legitimate 
attempts to acquire the Company, and, therefore, their actions constitute unfair
dealing and a breach of fiduciary duty to maximize shareholder value.

                                  THE PARTIES
                                  -----------
    2. Plaintiff William Steiner is, and at all relevant times was, the owner of
shares of common stock of Magma Power.

    3. Magma Power is a corporation duly organized and existing under the laws 
of the State of Nevada. The Company and its subsidiaries are engaged in the 
exploration for, and development of, geothermal resources and the use of such 
resources to generate electricity, including the development

                                       2

 
and operation of geothermal power plants. Magma Power maintains its principal 
executive offices at 4365 Executive Drive, San Diego, California 92121. Magma 
Power has approximately 24 million shares of common stock outstanding and 
approximately 2,260 stockholders of record. Magma Power's stock trades on the 
NASDAQ National Market System.

    4. Defendant Paul M. Pankratz ("Pankratz") is the Chairman of the Board of 
Directors of Magma Power. In 1993, Pankratz received from Magma Power $722,164 
in cash compensation.

    5. Defendant Ralph W. Boeker ("Boeker") is a director and the President and 
Chief Executive Officer of Magma Power. In 1993, Boeker received from Magma 
Power $1,177,228 in cash compensation.

    6. Defendants Lester L. Coleman, John D. Roach, Thomas C. Hinrichs, Roger L.
Kesseler, William R. Knee, Bent Petersen, J. Pedro Reinhard, James D. Shepard, 
and Louis A. Simpson are directors of Magma Power.

    7. The defendants named in paragraphs 4 through 6 are hereinafter referred 
to as the "Individual Defendants."

    8. Because of their positions as officers/directors of the Company, the 
Individual Defendants owe a fiduciary duty of loyalty and due care to plaintiff 
and the other members of the class.

    9. Each defendant herein is sued individually as a conspirator and aider and
abettor, as well as in his/her capacity as an officer and/or director of the 
Company, and the liability of each arises from the fact that he or she has

                                       3

 
engaged in all or part of the unlawful acts, plans, schemes, or transactions
complained of herein.

    10. By virtue of the acts and conduct alleged herein, the Individual 
Defendants, who control the actions of Magma Power, have breached and are 
breaching their fiduciary duties to Magma Power's public shareholders.

                           CLASS ACTION ALLEGATIONS
                           ------------------------

    11. Plaintiff brings this lawsuit pursuant to California Code of Civil 
Procedure, Section 382 on his own behalf and as a class action on behalf of all 
shareholders of Magma Power (except defendants herein and any person, firm, 
trust, corporation or other entity related to, controlled by or affiliated with 
any of the defendants) and their successors in interest (the "Class").

    12. This action is properly maintainable as a class action.

    13. The Class of shareholders for whose benefit this action is brought is so
numerous that joinder of all Class members is impracticable. Magma Power has 
over 24 million shares of common stock outstanding, owned by more than 2,260 
record shareholders. Members of the Class are scattered throughout the United 
States.

    14. There are questions of law and fact common to members of the Class that 
predominate over any questions affecting only individual members. The common 
questions include, inter alia, whether:

        a. defendants have breached their fiduciary

                                       4

 
duties owed by them to plaintiff and other members of the Class by failing and
refusing to attempt in good faith to maximize shareholder value in the sale of
Magma Power;

        b. defendants have entrenched themselves in office and deprived Magma 
    Power's public shareholders of the maximum value of their holdings;

        c. defendants have breached or aided and abetted the breach of the
    fiduciary duties owed by them to plaintiff and other members of the Class;

        d. defendants engaged in a plan and scheme to thwart and reject bona
    fide offers from third parties, including California Energy; and

        e. plaintiff and the other members of the Class are being and will
    continue to be injured by the wrongful conduct alleged herein and, if so,
    what is the proper remedy and/or measure of damages.

    15. The claims of plaintiff are typical of the claims of other members of
the Class and plaintiff has no interests that are adverse or antagonistic to the
interests of the Class.

    16. Plaintiff is committed to the vigorous prosecution of this action and 
has retained competent counsel experienced in litigation of this nature. 
Accordingly, plaintiff is an adequate representative of the Class and will 
fairly and adequately protect the interests of the Class.

    17. Plaintiff anticipates that there will not be any difficulty in the 
management of this litigation as a class action.

                                       5

 
    18. For the reasons stated herein, a class action is superior to other 
available methods for the fair and efficient adjudication of this action and the
claims asserted herein.

                            SUBSTANTIVE ALLEGATIONS

    19. By the acts, transactions, and courses of conduct alleged herein, 
defendants, individually and as part of a common plan and scheme and/or by 
aiding and abetting one another in total disregard of their fiduciary duties, 
are attempting to deprive plaintiff and the Class unfairly of the opportunity to
maximize the value of their investment in Magma Power.

    20. On September 19, 1994, after the close of trading, California Energy 
announced that it had sent a letter to defendants Pankratz and Boeker proposing 
the acquisition of Magma Power for approximately $840 million. Under the offer, 
Magma Power shareholders would receive $25 per share in cash and California 
Energy stock worth $10 per share in market value. The offer represents a premium
of approximately 22% over the closing price of Magma Power stock on September 
19, 1994 of $27.50 per share.

    21. According to the WALL STREET JOURNAL and the DOW JONES NEW WIRE, the two
companies have been discussing a possible business combination during the past 
12 months. In fact, according to California Energy's proposal letter, as 
recently as Thursday, September 15, 1994, defendants Pankratz and Boeker spoke 
with David L. Sokol, Chairman, President and Chief Executive Officer of 
California Energy, to discuss a

                                       6

 
business combination of the two companies. These overtures bore no fruit.

    22. Notwithstanding the apparent synergies of a business combination, 
defendants, during the past 12 months of overtures, have resisted the 
negotiation or execution of a definitive merger agreement and, as noted in the 
proposal letter, have sought to "move slowly in this matter." However, because 
of defendants' recalcitrance, California Energy could wait no longer for 
defendants to consider seriously their overtures for a business combination of 
the two companies.

    23. California Energy stressed that it wished to effect the transaction 
"amicably." In that regard, Sokol offered to meet with defendants to discuss and
"negotiate in good faith all aspects of [California Energy's] proposal." 
Financing the transaction would not, according to Sokol and its financial 
advisor, be a problem.

    24. Despite the significant value to Magma Power shareholders, defendants 
have indicated they do not intend to fairly consider the offer nor act with 
regard to the fiduciary duty they owe Magma Power's shareholders to fully inform
themselves about a business combination with California Energy.

    25. Defendants owe fundamental fiduciary obligations to Magma Power's 
shareholders to take all necessary and appropriate steps to maximize the value 
of their shares. In addition, the Individual Defendants have the responsibility 
to act independently so that the interests of Magma Power's public stockholders 
will be protected, to seriously consider all bona fide offers for Magma Power, 
and to conduct fair and active

                                       7

 
bidding procedures or other mechanisms for checking the market to assure that
the highest possible price is achieved. Further, the directors of Magma Power
must adequately ensure that no conflict of interest exists between the
Individual Defendants' own interests and their fiduciary obligations to maximize
stockholder value or, if such conflicts exist, to insure that all such conflicts
will be resolved in the best interests of the Company's shareholders.

    26. Magma Power represents a highly attractive acquisition candidate. 
Defendants' recalcitrance to negotiate a definitive merger agreement in the past
and their current resistance to seriously consider and promptly act upon 
California Energy's formal offer, have no valid business purpose, and simply 
evidences their disregard for the attractive premium being offered to Magma 
Power's shareholders. Defendants' conduct would deprive Magma Power's public 
shareholders of the very substantial control premium which California Energy is 
prepared to pay or of the enhanced premium that further negotiation or exposure 
of Magma Power to the market could provide.

    27. Because defendants dominate and control the business and corporate 
affairs of Magma Power and because they are in possession of private corporate 
information concerning Magma Power's assets, businesses and future prospects, 
there exists an imbalance and disparity of knowledge of economic power between 
defendants and the public shareholders of Magma Power. This discrepancy makes it
grossly and inherently unfair for defendants to entrench themselves at the 
expense of its

                                       8

 
public shareholders.

    28. The Individual  Defendants have breached their fiduciary and other 
common law duties owed to plaintiff and the other members of the Class in that 
they have not and are not exercising independent business judgment and have 
acted and are acting to the detriment of the Class.

    29. The Individual Defendants were and are under a duty to:

        a. fully inform themselves before taking, or agreeing to refrain from
    taking, action;

        b. elicit, promote, consider and evaluate reasonable and bona fide
    offers for the Company, including California Energy's overtures and offer;

        c. act in the interests of the equity owners and other constituencies of
    the Company;

        d. refrain from acting in their own personal self-interest or in the
    personal interest of other Board members;

        f. maximize shareholder value;

        g. obtain the best financial and other terms when the Company, or
    control of the Company, is for sale or the Company's independent existence
    will be materially altered by a transaction; and

        i. act in accordance with their fiduciary duties of care and loyalty.

    30. In connection with the conduct described herein,

                                       9

 
the Individual Defendants breached the fiduciary duties identified above. 
Defendants have failed and/or refused to take those steps necessary to ensure 
that Magma Power's shareholders will receive maximum value for their shares of 
Magma Power stock. Defendants have thus refused to seriously consider California
Energy's previous overtures and the pending offer, and have failed to announce 
any active auction or open bidding procedures best calculated to maximize 
shareholder value in selling the Company.

    31. The Individual Defendants are acting to entrench themselves in their 
offices and positions and maintain their substantial salaries and perquisites, 
all at the expense and to the detriment of the public shareholders of Magma 
Power.

    32. By the acts, transactions and courses of conduct alleged herein, the 
Individual Defendants, individually and as part of a common plan and scheme in 
breach of their fiduciary duties and obligations, are attempting unfairly to 
deprive plaintiff and the other members of the Class of the premium they could 
realize in an acquisition transaction and to ensure continuance of their 
positions as directors and officers, all to the detriment of Magma Power and its
public shareholders. The Individual Defendants have been engaged in a wrongful 
effort to entrench themselves in their offices and positions of control and 
prevent the acquisition of Magma Power, except on terms which would further 
their own personal interests.

    33. As a result of the actions of the Individual Defendants, plaintiff and 
the other members of the Class have been and will be damaged in that they have 
not and will not

                                      10

 
receive their fair proportion of the value of Magma Power's assets and 
businesses and/or have been and will be prevented from obtaining a fair and 
adequate price for their shares of Magma Power's common stock.

    34. Plaintiff seeks preliminary and permanent injunctive relief and
declaratory relief preventing defendants from inequitably and unlawfully
depriving plaintiff and the Class of their rights to realize a full and fair
value for their stock at a substantial premium over the market price, by
unlawfully entrenching themselves in their positions of control, and to compel
defendants to carry out their fiduciary duties to maximize shareholder value.

    35. Only through the exercise of this Court's equitable powers can plaintiff
be fully protected from the immediate and irreparable injury which defendants' 
actions threaten to inflict. Defendants are precluding the shareholders' 
enjoyment of the full economic value of their investment by failing to proceed 
expeditiously and in good faith to evaluate and pursue a premium acquisition 
proposal which would provide cash and stock for all shares at a very attractive 
price.

    36. Unless enjoined by the Court, defendants will continue to breach their 
fiduciary duties owed to plaintiff and the members of the Class, and/or aid and 
abet and participate in such breaches of duty, and will prevent the sale of 
Magma Power at a substantial premium, all to the irreparable harm of plaintiffs 
and other members of the Class.

    37. Plaintiff and the Class have no adequate remedy

                                      11

 
at law.

    WHEREFORE, plaintiff demands judgment as follows:

    (a) Declaring this to be a proper class action and certifying plaintiff as a
class representative;

    (b) Ordering the Individual Defendants to carry out their fiduciary duties 
to plaintiffs and the other members of the Class by announcing their intention 
to:

        (i) cooperate fully with any entity or person, including California
    Energy, having a bona fide interest in proposing any transactions that would
    maximize shareholder value, including but not limited to, a merger or
    acquisition of Magma Power;

        (ii) immediately undertake an appropriate evaluation of Magma Power's
    worth as a merger/acquisition candidate;

        (iii) take all appropriate steps to enhance Magma Power's value and
    attractiveness as a merger/acquisition candidate;

        (iv) take all appropriate steps to effectively expose Magma Power to the
    marketplace in an effort to create an active auction of the Company;

        (v) act independently so that the interests of the Company's public
    shareholders will be protected; and

        (vi) adequately ensure that no conflicts of interest exist between the
    Individual Defendants' own interest and their fiduciary obligation to
    maximize shareholder value or, in the event such conflicts exist, to ensure
    that all

                                      12

 
conflicts of interest are resolved in the best interests of the public
shareholders of Magma Power;

    (c) Ordering the Individual Defendants, jointly and severally to account to 
plaintiff and the Class for all damages suffered and to be suffered by them as a
result of the acts and transactions alleged herein;

    (e) Awarding plaintiff the costs and disbursements of this action, including
a reasonable allowance for plaintiff's attorneys' and experts' fees; and

    (f) Granting such other and further relief as may be just and proper.
