President Bush has made it a central theme of his second term to simplify the U.S. tax code. Among the options that may be under consideration are replacing or supplementing the corporate income tax with a value-added-tax, stripping away many tax subsidies, and eliminating taxes on interest, dividends and other returns to capital. Significant tax reform has the potential to have a material effect on our business, financial condition, future results and cash flow. It could reduce or eliminate the value that geothermal companies receive from the current tax subsidies. Any restrictions or tightening of the rules for lease or partnership transactions — whether or not part of major tax reform — could also materially affect our business, financial condition, future results and cash flow.

Any such changes could significantly increase the regulatory-related compliance and other expenses incurred by the projects and could significantly reduce or entirely eliminate the revenues generated by one or more of the projects, which in turn would reduce our net income and could materially and adversely affect our business, financial condition, future results and cash flow.

The costs of compliance with environmental laws and of obtaining and maintaining environmental permits and governmental approvals required for construction and/or operation, which currently are significant, may increase in the future and could materially and adversely affect our business, financial condition, future results and cash flow; any non-compliance with such laws or regulations may result in the imposition of liabilities which could materially and adversely affect our business, financial condition, future results and cash flow.

Our projects are required to comply with numerous domestic and foreign federal, regional, state and local statutory and regulatory environmental standards and to maintain numerous environmental permits and governmental approvals required for construction and/or operation. Some of the environmental permits and governmental approvals that have been issued to the projects contain conditions and restrictions, including restrictions or limits on emissions and discharges of pollutants and contaminants, or may have limited terms. If we fail to satisfy these conditions or comply with these restrictions, or with any statutory or regulatory environmental standards, we may become subject to regulatory enforcement action and the operation of the projects could be adversely affected or be subject to fines, penalties or additional costs. In addition, we may not be able to renew, maintain or obtain all environmental permits and governmental approvals required for the continued operation or further development of the projects. As of the date of this registration statement, we have not yet obtained certain permits and government approvals required for the completion and successful operation of projects under construction or enhancement. In addition, a nearby municipality has informed our Amatitlan project that an additional building permit should be obtained from such municipality before construction commences. In what appears to be a related occurrence, a group of demonstrators from the municipality have attempted to disrupt the access road to our Amatitlan project. A separate group of demonstrators from another municipality have turned out in support of the project, and Guatemalan authorities have assisted in maintaining access to the project. Our failure to renew, maintain or obtain required permits or governmental approvals, including the permits and approvals necessary for operating projects under construction or enhancement and the Amatitlan project, could cause our operations to be limited or suspended. Environmental laws, ordinances and regulations affecting us can be subject to change and such change could result in increased compliance costs, the need for additional capital expenditures, or otherwise adversely affect us.

We could be exposed to significant liability for violations of hazardous substances laws because of the use or presence of such substances at our projects.

Our projects are subject to numerous domestic and foreign federal, regional, state and local statutory and regulatory standards relating to the use, storage and disposal of hazardous substances. We use isobutane, isopentane, industrial lubricants and other substances at our projects which are or could become classified as hazardous substances. If any hazardous substances are found to have been released into the environment at or by the projects, we could become liable for the investigation and removal of those substances, regardless of their source and time of release. If we fail to comply with these laws, ordinances or regulations (or any change thereto), we could be subject to civil or criminal liability, the imposition of liens or fines, and large expenditures to bring the projects into compliance. Furthermore, in the United States, we can be held liable for the cleanup of releases of hazardous

S-19

Table of Contents

substances at other locations where we arranged for disposal of those substances, even if we did not cause the release at that location. The cost of any remediation activities in connection with a spill or other release of such substances could be significant.

We believe that at one time there may have been a gas station located on the Mammoth project site, but because of significant surface disturbance and construction since that time further physical evaluation of the former gas station site has been impractical. There may be soil or groundwater contamination and related potential liabilities of which we are unaware related to this site, which may be significant and may adversely and materially affect our operations and revenues.

We may not be able to successfully integrate companies which we may acquire in the future, which could materially and adversely affect our business, financial condition, future results and cash flow.

Our strategy is to continue to expand in the future, including through acquisitions. Integrating acquisitions is often costly, and we may not be able to successfully integrate our acquired companies with our existing operations without substantial costs, delays or other adverse operational or financial consequences. Integrating our acquired companies involves a number of risks that could materially and adversely affect our business, including:

	•	failure of the acquired companies to achieve the results we expect;

	•	inability to retain key personnel of the acquired companies;

	•	risks associated with unanticipated events or liabilities; and

	•	the difficulty of establishing and maintaining uniform standards, controls, procedures and policies, including accounting controls and procedures.

If any of our acquired companies suffers customer dissatisfaction or performance problems, the same could adversely affect the reputation of our group of companies and could materially and adversely affect our business, financial condition, future results and cash flow.

The power generation industry is characterized by intense competition, and we encounter competition from electric utilities, other power producers, and power marketers that could materially and adversely affect our business, financial condition, future results and cash flow.

The power generation industry is characterized by intense competition from electric utilities, other power producers and power marketers. In recent years, there has been increasing competition in the sale of electricity, in part due to excess capacity in a number of U.S. markets and an emphasis on short-term or ‘‘spot’’ markets, and competition has contributed to a reduction in electricity prices. For the most part, we expect that power purchasers interested in long-term arrangements will engage in ‘‘competitive bid’’ solicitations to satisfy new capacity demands. This competition could adversely affect our ability to obtain power purchase agreements and the price paid for electricity by the relevant power purchasers. There is also increasing competition between electric utilities. This competition has put pressure on electric utilities to lower their costs, including the cost of purchased electricity, and increasing competition in the future will put further pressure on power purchasers to reduce the prices at which they purchase electricity from us.

The existence of a prolonged force majeure event or a forced outage affecting a project could reduce our net income and materially and adversely affect our business, financial condition, future results and cash flow.

The operation of our subsidiaries' geothermal power plants is subject to a variety of risks discussed elsewhere in these risk factors, including events such as fires, explosions, earthquakes, landslides, floods, severe storms or other similar events.

If a project experiences an occurrence resulting in a force majeure event, our subsidiary owning that project would be excused from its obligations under the relevant power purchase agreement. However, the relevant power purchaser may not be required to make any capacity and/or energy payments with respect to the affected project or plant so long as the force majeure event continues and, pursuant to certain of our power purchase agreements, will have the right to prematurely

S-20

---

Table of Contents

terminate the power purchase agreement. Additionally, to the extent that a forced outage has occurred, the relevant power purchaser may not be required to make any capacity and/or energy payments to the affected project, and if as a result the project fails to attain certain performance requirements under certain of our power purchase agreements, the purchaser may have the right to permanently reduce the contract capacity (and, correspondingly, the amount of capacity payments due pursuant to such agreements in the future), seek refunds of certain past capacity payments, and/or prematurely terminate the power purchase agreement. As a consequence, we may not receive any net revenues from the affected project or plant other than the proceeds from any business interruption insurance that applies to the force majeure event or forced outage after the relevant waiting period, and may incur significant liabilities in respect of past amounts required to be refunded. Accordingly, our business, financial condition, future results and cash flows could be materially and adversely affected. Recently, due to hurricane activity, the access roads and the piping from the wells to the Zunil power plant were damaged and as a result, the project was not in operation from October 14, 2005 to March 10, 2006.

The existence of a force majeure event or a forced outage affecting the transmission system of the Imperial Irrigation District could reduce our net income and materially and adversely affect our business, financial condition, future results and cash flow.

If the transmission system of the Imperial Irrigation District experiences a force majeure event or a forced outage which prevents it from transmitting the electricity from the Heber 1 and 2 projects or the Ormesa project to the relevant power purchaser, the relevant power purchaser would not be required to make energy payments for such non-delivered electricity and may not be required to make any capacity payments with respect to the affected project so long as such force majeure event or forced outage continues. Our revenues for the year ended December 31, 2005, from the projects utilizing the Imperial Irrigation District transmission system, were approximately $85.9 million. The impact of such force majeure would depend on the duration thereof, with longer outages resulting in greater revenue loss.

Some of our leases will terminate if we do not extract geothermal resources in ‘‘commercial quantities’’, thus requiring us to enter into new leases or secure rights to alternate geothermal resources, none of which may be available on terms as favorable to us as any such terminated lease, if at all.

Most of our geothermal resource leases are for a fixed primary term, and then continue for so long as geothermal resources are extracted in ‘‘commercial quantities’’ or pursuant to other terms of extension. The land covered by some of our leases is undeveloped and has not yet produced geothermal resources in ‘‘commercial quantities’’. Leases that cover land which remains undeveloped and does not produce, or does not continue to produce, geothermal resources in commercial quantities and leases that we allow to expire, will terminate. In the event that a lease is terminated and we determine that we will need that lease once the applicable project is operating, we would need to enter into one or more new leases with the owner(s) of the premises that are the subject of the terminated lease(s) in order to develop geothermal resources from, or inject geothermal resources into, such premises or secure rights to alternate geothermal resources or lands suitable for injection, all of which may not be possible or could result in increased cost to us, which could materially and adversely affect our business, financial condition, future results and cash flow.

Our Bureau of Land Management leases may be terminated if we fail to comply with any of the provisions of the Geothermal Steam Act of 1970 or if we fail to comply with the terms or stipulations of such leases, which may materially and adversely affect our business and operations.

Pursuant to the terms of our Bureau of Land Management (which we refer to as BLM) leases, we are required to conduct our operations on BLM-leased land in a workmanlike manner and in accordance with all applicable laws and BLM directives and to take all mitigating actions required by the BLM to protect the surface of and the environment surrounding the relevant land. Additionally, certain BLM leases contain additional requirements, some of which relate to the mitigation or avoidance of disturbance of any antiquities, cultural values or threatened or endangered plants or animals, the payment of royalties for timber and the imposition of certain restrictions on residential development on the leased land. In the event of a default under any BLM lease, or the failure to

S-21

---

Table of Contents

comply with such requirements, or any non-compliance with any of the provisions of the Geothermal Steam Act of 1970 or regulations issued thereunder, the BLM may, 30 days after notice of default is provided to our relevant project subsidiary, suspend our operations until the requested action is taken or terminate the lease, either of which could materially and adversely affect our business, financial condition, future results and cash flow.

Some of our leases (or subleases) could terminate if the lessor (or sublessor) under any such lease (or sublease) defaults on any debt secured by the relevant property, thus terminating our rights to access the underlying geothermal resources at that location.

The fee interest in the land which is the subject of some of our leases (or subleases) may currently be or may become subject to encumbrances securing loans from third party lenders to the lessor (or sublessor). Our rights as lessee (or sublessee) under such leases (or subleases) are or may be subject and subordinate to the rights of any such lender. Accordingly, a default by the lessor (or sublessor) under any such loan could result in a foreclosure on the underlying fee interest in the property and thereby terminate our leasehold interest and result in the shutdown of the project located on the relevant property and/or terminate our right of access to the underlying geothermal resources required for our operations.

In addition, a default by a sublessor under its lease with the owner of the property that is the subject of our sublease could result in the termination of such lease and thereby terminate our sublease interest and our right to access the underlying geothermal resources required for our operations.

Current and future urbanizing activities and related residential, commercial and industrial developments may encroach on or limit geothermal activities in the areas of our projects, thereby affecting our ability to utilize, access, inject and/or transport geothermal resources on or underneath the affected surface areas.

Current and future urbanizing activities and related residential, commercial and industrial development may encroach on or limit geothermal activities in the areas of our projects, thereby affecting our ability to utilize, access, inject and/or transport geothermal resources on or underneath the affected surface areas. In particular, the Heber projects and the Gould project rely on an area, which we refer to as the Heber Known Geothermal Resource Area or Heber KGRA, for the geothermal resource necessary to generate electricity at the Heber projects and Gould project. Imperial County has adopted a ‘‘specific plan area’’ that covers the Heber KGRA, which we refer to as the ‘‘Heber Specific Plan Area’’. The Heber Specific Plan Area allows commercial, residential, industrial and other employment oriented development in a mixed-use orientation, which currently includes geothermal uses. Several of the landowners from whom we hold geothermal leases have expressed an interest in developing their land for residential, commercial, industrial or other surface uses in accordance with the parameters of the Heber Specific Plan Area. Currently, Imperial County's Heber Specific Plan Area is coordinated with the cities of El Centro and Calexio. There has been ongoing underlying interest since the early 1990s to incorporate the community of Heber. While any incorporation process would likely take several years, if Heber were to be incorporated, the City of Heber could replace Imperial County as the governing land use authority, which, depending on its policies, could have a significant effect on land use and availability of geothermal resources.

Current and future development proposals within Imperial County and the City of Calexico, applications for annexations to the City of Calexico, and plans to expand public infrastructure may affect surface areas within the Heber KGRA, thereby limiting our ability to utilize, access, inject and/or transport the geothermal resource on or underneath the affected surface area that is necessary for the operation of our Heber projects and Gould project, which could adversely affect our operations and reduce our revenues.

Current transportation construction works and urban developments in the vicinity of our Steamboat complex of projects in Nevada may also affect future permitting for geothermal operations relating to those projects. Such works and developments include the extension of an interstate

highway (to be named U.S. 580) by the Nevada Department of Transportation, the construction of a new casino hotel and other commercial or industrial developments on land in the vicinity of our Steamboat projects.

We depend on key personnel for the success of our business.

Our success is largely dependent on the skills, experience and efforts of our senior management team and other key personnel. In particular, our success depends on the continued efforts of Lucien Bronicki, Dita Bronicki, Hezy Ram, Nadav Amir, Yoram Bronicki and other key employees. The loss of the services of any key employee could materially harm our business, financial condition, future results and cash flow. Although to date we have been successful in retaining the services of senior management and have entered into employment agreements with Lucien Bronicki, Dita Bronicki, Hezy Ram and Yoram Bronicki, such members of our senior management may terminate their employment agreements without cause and with notice periods ranging from 90 to 180 days. We may also not be able to locate or employ on acceptable terms qualified replacements for our senior management or key employees if their services were no longer available.

Our projects have generally been financed through a combination of parent company loans and limited− or non-recourse project finance debt and lease financing. If our project subsidiaries default on their obligations under such limited− or non-recourse debt or lease financing, we may be required to make certain payments to the relevant debt holders and if the collateral supporting such leveraged financing structures is foreclosed upon, we may lose certain of our projects.

Our projects have generally been financed using a combination of parent company loans and limited or non-recourse project finance debt or lease financing. Non-recourse project finance debt or lease financing refers to financing arrangements that are repaid solely from the project’s revenues and are secured by the project’s physical assets, major contracts, cash accounts and, in many cases, our ownership interest in the project subsidiary. Limited−recourse project finance debt refers to our additional agreement, as part of the financing of a project, to provide limited financial support for the project subsidiary in the form of limited guarantees, indemnities, capital contributions and agreements to pay certain debt service deficiencies. If our project subsidiaries default on their obligations under the relevant debt documents, creditors of a limited recourse project financing will have direct recourse to us, to the extent of our limited recourse obligations, which may require us to use distributions received by us from other projects, as well as other sources of cash available to us, in order to satisfy such obligations. In addition, if our project subsidiaries default on their obligations under the relevant debt documents (or a default under such debt documents arises as a result of a cross-default to the debt documents of some of our other projects) and the creditors foreclose on the relevant collateral, we may lose our ownership interest in the relevant project subsidiary or our project subsidiary owning the project would only retain an interest in the physical assets, if any, remaining after all debts and obligations were paid in full.

Changes in costs and technology may significantly impact our business by making our power plants and products less competitive.

A basic premise of our business model is that generating baseload power at geothermal power plants achieves economies of scale and produces electricity at a competitive price. However, traditional coal-fired systems and gas-fired systems may under certain economic conditions produce electricity at lower average prices than our geothermal plants. In addition, there are other technologies that can produce electricity, most notably fossil fuel power systems, hydroelectric systems, fuel cells, microturbines, windmills and photovoltaic (solar) cells. Some of these alternative technologies currently produce electricity at a higher average price than our geothermal plants; however, research and development activities are ongoing to seek improvements in such alternate technologies and their cost of producing electricity is gradually declining. It is possible that advances will further reduce the cost of alternate methods of power generation to a level that is equal to or below that of most geothermal power generation technologies. If this were to happen, the competitive advantage of our projects may be significantly impaired.

Our expectations regarding the market potential for the development of recovered energy-based power generation may not materialize, and as a result we may not derive any significant revenues from this line of business.

We have identified recovered energy-based power generation as a significant market opportunity for us. Demand for our recovered energy-based power generation units may not materialize or grow at the levels that we expect. We currently face competition in this market from manufacturers of conventional steam turbines and may face competition from other related technologies in the future. If this market does not materialize at the levels that we expect, such failure may materially and adversely affect our business, financial condition, future results and cash flow.

Our intellectual property rights may not be adequate to protect our business.

Our intellectual property rights may not be adequate to protect our business. While we occasionally file patent applications, patents may not be issued on the basis of such applications or, if patents are issued, they may not be sufficiently broad to protect our technology. In addition, any patents issued to us or for which we have use rights may be challenged, invalidated or circumvented.

In order to safeguard our unpatented proprietary know-how, trade secrets and technology, we rely primarily upon trade secret protection and non-disclosure provisions in agreements with employees and others having access to confidential information. These measures may not adequately protect us from disclosure or misappropriation of our proprietary information.

Even if we adequately protect our intellectual property rights, litigation may be necessary to enforce these rights, which could result in substantial costs to us and a substantial diversion of management attention. Also, while we have attempted to ensure that our technology and the operation of our business do not infringe other parties’ patents and proprietary rights, our competitors or other parties may assert that certain aspects of our business or technology may be covered by patents held by them. Infringement or other intellectual property claims, regardless of merit or ultimate outcome, can be expensive and time-consuming and can divert management’s attention from our core business.

We are subject to risks associated with a changing economic and political environment, which may adversely affect our financial stability or the financial stability of our counterparties.

The risk of terrorist attacks in the United States or elsewhere continues to remain a potential source of disruption to the nation’s economy and financial markets in general. The availability and cost of capital for our business and that of our competitors has been adversely affected by the bankruptcy of Enron Corp. and events related to the California electric market crisis. Additionally, the recent rise in fuel costs may make it more expensive for our customers to operate their businesses. These events could constrain the capital available to our industry and could adversely affect our financial stability and the financial stability of our transaction counterparties.

Possible fluctuations in the cost of construction, raw materials and drilling may materially and adversely affect our business, financial condition, future results and cash flow.

Our manufacturing operations are dependent on the supply of various raw materials, including primarily steel and aluminum, and on the supply of various industrial equipment components that we use. We currently obtain all such materials and equipment at prevailing market prices. We are not dependent on any one supplier and do not have any long-term agreements with any of our suppliers. We have recently experienced increases in the cost of raw materials and in transportation costs. We have also experienced an increase in construction costs, which we expect may intensify due to recent hurricane activity, and an increase in drilling costs. To the extent not otherwise passed along to our customers, these and future cost increases of such raw materials and equipment could adversely affect our profit margins.

Conditions in Israel, where the majority of our senior management and all of our production and manufacturing facilities are located, may adversely affect our operations and may limit our ability to produce and sell our products or manage our projects.

Operations in Israel accounted for approximately 25.2%, 25.6% and 51% of our operating expenses in the year ended December 31, 2005, 2004 and 2003, respectively. Political, economic and

S-24

security conditions in Israel directly affect our operations. Since the establishment of the State of Israel in 1948, a number of armed conflicts have taken place between Israel and its Arab neighbors, and the continued state of hostility, varying in degree and intensity, has led to security and economic problems for Israel. Since October 2000, there has been a significant increase in violence, primarily in the West Bank and Gaza Strip. As a result, negotiations between Israel and representatives of the Palestinian Authority have been sporadic and have failed to result in peace. We could be adversely affected by hostilities involving Israel, the interruption or curtailment of trade between Israel and its trading partners, or a significant downturn in the economic or financial condition of Israel. In addition, the sale of products manufactured in Israel may be adversely affected in certain countries by restrictive laws, policies or practices directed toward Israel or companies having operations in Israel.

In addition, some of our employees in Israel are subject to being called upon to perform military service in Israel, and their absence may have an adverse effect upon our operations. Generally, unless exempt, male adult citizens of Israel under the age of 41 are obligated to perform up to 36 days of military reserve duty annually. Additionally, all such citizens are subject to being called to active duty at any time under emergency circumstances.

These events and conditions could disrupt our operations in Israel, which could materially harm our business, financial condition, future results and cash flow.

Failure to comply with certain conditions and restrictions associated with tax benefits provided to Ormat Systems Ltd. by the Government of Israel as an ‘‘approved enterprise’’ may require us to refund such tax benefits and pay future taxes in Israel at higher rates.

Our subsidiary, Ormat Systems Ltd., which we refer to as Ormat Systems, has received ‘‘approved enterprise’’ status under Israel’s Law for Encouragement of Capital Investments, 1959, with respect to two of its investment programs. As an approved enterprise, our subsidiary is exempt from Israeli income taxes with respect to revenues derived from the approved investment program for a period of two years commencing on the year it first generates profits from the approved investment program, and thereafter such revenues are subject to a reduced Israeli income tax rate of 25% for an additional five years. These benefits are subject to certain conditions set forth in the certificate of approval from Israel’s Investment Center, which include, among other things, a requirement that Ormat Systems comply with Israeli intellectual property law, that all transactions between Ormat Systems and our affiliates be at arms length, and that there will be no change in control of, on a cumulative basis, more than 49% of Ormat Systems’ capital stock (including by way of a public or private offering) without the prior written approval of the Investment Center. If Ormat Systems does not comply with these conditions, in whole or in part, it would be required to refund the amount of tax benefits (as adjusted by the Israeli consumer price index and for accrued interest) and would no longer benefit from the reduced Israeli tax rate, which could have an adverse effect on our financial condition, future results and cash flow. If Ormat Systems distributes dividends out of revenues derived during the tax exemption period from the approved investment program, it will be subject, in the year in which such dividend is paid, to Israeli income tax on the distributed dividend.

If our parent defaults on its lease agreement with the Israel Land Administration, or is involved in a bankruptcy or similar proceeding, our rights and remedies under certain agreements pursuant to which we acquired our products business and pursuant to which we sublease our land and manufacturing facilities from our parent may be adversely affected.

We acquired our business relating to the manufacture and sale of products for electricity generation and related services from our parent, Ormat Industries. In connection with that acquisition, we entered into a sublease with Ormat Industries for the lease of the land and facilities in Yavne, Israel where our manufacturing and production operations are conducted and where our Israeli offices are located. Under the terms of our parent’s lease agreement with the Israel Land Administration, any sublease for a period of more than five years may require the prior approval of the Israel Land Administration. As a result, the initial term of our sublease with Ormat Industries is for a period of four years and eleven months beginning on July 1, 2004, extendable to twenty-five years less one day (which includes the initial term). The consent of the Israel Land Administration was obtained for a period of the shorter of (i) 25 years or (ii) the remaining period of the underlying lease agreement

S-25

with the Israel Land Administration, which terminates between 2018 and 2047. If our parent was to breach its obligations to the Israel Land Administration under its lease agreement, the Israel Land Administration could terminate the lease agreement and, consequently, our sublease would terminate as well.

As part of the acquisition described in the preceding paragraph, we also entered into a patent license agreement with Ormat Industries, pursuant to which we were granted an exclusive license for certain patents and trademarks relating to certain technologies that are used in our business. If a bankruptcy case were commenced by or against our parent, it is possible that performance of all or part of the agreements entered into in connection with such acquisition (including the lease of land and facilities described above) could be stayed by the bankruptcy court in Israel or rejected by a liquidator appointed pursuant to the Bankruptcy Ordinance in Israel and thus not be enforceable. Any of these events could have a material and adverse effect on our business, financial condition, future results and cash flow.

We are a holding company and our revenues depend substantially on the performance of our subsidiaries and the projects they operate, most of which are subject to restrictions and taxation on dividends and distributions.

We are a holding company whose primary assets are our ownership of the equity interests in our subsidiaries. We conduct no other business and, as a result, we depend entirely upon our subsidiaries’ earnings and cash flow.

The agreements pursuant to which most of our subsidiaries have incurred debt restrict the ability of these subsidiaries to pay dividends, make distributions or otherwise transfer funds to us prior to the satisfaction of other obligations, including the payment of operating expenses, debt service and replenishment or maintenance of cash reserves. In the case of some of our projects, such as the Mammoth project, there may be certain additional restrictions on dividend distributions pursuant to our agreements with our partners. Further, if we elect to receive distributions of earnings from our foreign operations, we may incur United States taxes on account of such distributions, net of any available foreign tax credits. In all of the foreign countries where our existing projects are located, dividend payments to us are also subject to withholding taxes. Each of the events described above may reduce or eliminate the aggregate amount of revenues we can receive from our subsidiaries.

Some of our directors that also hold positions with our parent may have conflicts of interest with respect to matters involving both companies.

Three of our seven directors are directors and/or officers of Ormat Industries. These directors will have fiduciary duties to both companies and may have conflicts of interest on matters affecting both us and our parent, and in some circumstances may have interests adverse to our interests. Our Chairman, Director and Chief Technology Officer, Mr. Bronicki, is the Chairman of our parent, and our Chief Executive Officer and Director, Mrs. Bronicki, is the Chief Executive Officer of our parent.

The Sarbanes-Oxley Act of 2002 imposes significant regulatory, corporate and operational requirements on the Company. Failure to comply with such provisions may have significant adverse consequences to the Company

As a public company, we are subject to the Sarbanes-Oxley Act of 2002 (the SOX Act). The SOX Act contains a variety of provisions affecting public companies, including but not limited to, corporate governance requirements, our relationship with our auditors, evaluation of our internal disclosure controls and procedures and evaluation of our internal control over financial reporting.

Risks Related to Our Common Stock

Our controlling stockholders may take actions that conflict with your interests.

As of March 31, 2006, our parent, Ormat Industries holds approximately 77.2% of our common stock. Bronicki Investments Ltd. holds approximately 29.7% of outstanding shares of common stock of

S-26

Table of Contents

Ormat Industries Ltd. as of March 31, 2006 (27.5% on a fully diluted basis). Bronicki Investments Ltd. is a privately held Israeli company and is controlled by Lucien and Dita Bronicki. Because of these holdings, our parent company will be able to exercise control over all matters requiring stockholder approval, including the election of directors, amendment of our certificate of incorporation and approval of significant corporate transactions, and they will have significant control over our management and policies. The directors elected by these stockholders will be able to significantly influence decisions affecting our capital structure. This control may have the effect of delaying or preventing changes in control or changes in management, or limiting the ability of our other stockholders to approve transactions that they may deem to be in their best interest. For example, our controlling stockholders will be able to control the sale or other disposition of our products business to another entity or the transfer of such business outside of the State of Israel; as such action requires the affirmative vote of at least 75% of our outstanding shares.

The price of our common stock may fluctuate substantially and your investment may decline in value.

The market price of our common stock is likely to be highly volatile and may fluctuate substantially due to many factors, including:

	•	actual or anticipated fluctuations in our results of operations including as a result of seasonal variations in our electricity-based revenues;

	•	variance in our financial performance from the expectations of market analysts;

	•	conditions and trends in the end markets we serve and changes in the estimation of the size and growth rate of these markets;

	•	announcements of significant contracts by us or our competitors;

	•	changes in our pricing policies or the pricing policies of our competitors;

	•	loss of one or more of our significant customers;

	•	legislation;

	•	changes in market valuation or earnings of our competitors;

	•	the trading volume of our common stock; and

	•	general economic conditions.

In addition, the stock market in general, and the New York Stock Exchange and the market for energy companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of particular companies affected. These broad market and industry factors may materially harm the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against that company. Such litigation, if instituted against us, could result in substantial costs and a diversion of management’s attention and resources, which could materially harm our business, financial condition, future results and cash flow.

Future sales of common stock by some of our existing stockholders could cause our stock price to decline.

As of the date of this prospectus supplement, our parent, Ormat Industries, holds approximately 77.2% of our outstanding common stock and some of our directors, officers and employees also hold shares of our outstanding common stock. Sales of such shares in the public market, as well as shares we may issue upon exercise of outstanding options, could cause the market price of our common stock to decline. On November 10, 2004, we entered into a registration rights agreement with Ormat Industries whereby Ormat Industries may require us to register our common stock held by it or its directors, officers and employees with the Securities and Exchange Commission or to include our common stock held by it or its directors, officers and employees in an offering and sale by us.

Provisions in our charter documents and Delaware law may delay or prevent acquisition of us, which could adversely affect the value of our common stock.

Our restated certificate of incorporation and our bylaws contain provisions that could make it harder for a third party to acquire us without the consent of our Board of Directors. These provisions do not permit actions by our stockholders by written consent. In addition, these provisions include procedural requirements relating to stockholder meetings and stockholder proposals that could make stockholder actions more difficult. Our Board of Directors is classified into three classes of directors serving staggered, three-year terms and may be removed only for cause. Any vacancy on the Board of Directors may be filled only by the vote of the majority of directors then in office. Our Board of Directors has the right to issue preferred stock without stockholder approval, which could be used to institute a ‘‘poison pill’’ that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our Board of Directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. Although we believe these provisions provide for an opportunity to receive a higher bid by requiring potential acquirers to negotiate with our Board of Directors, these provisions apply even if the offer may be considered beneficial by some stockholders.

 USE OF PROCEEDS 

We estimate that the net proceeds we will receive from this offering, based on an offering price of $35.50 per share, will be approximately $117.2 million, or approximately $135.0 million if the underwriters exercise their option to purchase additional securities in full, in each case after deducting the underwriting discounts and commissions and estimated expenses of this offering payable by us. We expect to use the aggregate net proceeds from this offering for our general corporate purposes and those of our consolidated subsidiaries, which may include construction of geothermal and recovered energy generation power plants and other investments, and financing possible acquisitions.

 DIVIDEND POLICY 

We have adopted a dividend policy pursuant to which we expect to distribute at least 20% of our annual profits available for distribution by way of quarterly dividends. In determining whether there are profits available for distribution, our board of directors will take into account our business plan and current and expected obligations, and no distribution will be made that in the judgment of our board of directors would prevent us from meeting such business plan or obligations.

Notwithstanding this policy, dividends will be paid only when, as and if approved by our board of directors out of funds legally available therefor. The actual amount and timing of dividend payments will depend upon our financial condition, results of operations, business prospects and such other matters as the board may deem relevant from time to time. Even if profits are available for the payment of dividends, the board of directors could determine that such profits should be retained for an extended period of time, used for working capital purposes, expansion or acquisition of businesses or any other appropriate purpose. As a holding company, we are dependent upon the earnings and cash flow of our subsidiaries in order to fund any dividend distributions, and, as a result, we may not be able to pay dividends in accordance with our policy. Our board of directors may, from time to time, examine our dividend policy and may, in its absolute discretion, change such policy.

 UNITED STATES FEDERAL TAX CONSEQUENCES TO NON-U.S. HOLDERS 

The following description sets forth the material United States federal income and estate tax consequences that may be relevant to Non-U.S. Holders, as defined below, with respect to the acquisition, ownership and disposition of our common stock. This description addresses only the United States federal income and estate tax considerations of holders that are initial purchasers of our common stock pursuant to this Offeringand that will hold our common stock as capital assets. This description does not address tax considerations applicable to holders that are U.S. persons or that may be subject to special tax rules, including:

	•	financial institutions or insurance companies;

	•	real estate investment trusts, regulated investment companies or grantor trusts;

	•	dealers or traders in securities or currencies;

	•	tax-exempt entities;

	•	persons that received our stock as compensation for the performance of services;

	•	persons that will hold our stock as part of a ‘‘hedging’’ or ‘‘conversion’’ transaction or as a position in a ‘‘straddle’’ for United States federal income tax purposes;

	•	persons that have a ‘‘functional currency’’ other than the U.S. dollar;

	•	holders that own or are deemed to own 10% or more, by voting power or value, of our stock;

	•	certain former citizens or long-term residents of the United States; or

	•	certain persons who receive common stock or compensation for the performance of services rendered.

Moreover, except as set forth below, this description does not address the United States federal gift or alternative minimum tax consequences of the acquisition, ownership and disposition of our common stock.

This description is based on the Internal Revenue Code of 1986, as amended, which we refer to as the Code, existing, proposed and temporary United States Treasury Regulations and judicial and administrative interpretations thereof, in each case as in effect and available on the date hereof. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax consequences described below.

For purposes of this description, a ‘‘Non-U.S. Holder’’ is a beneficial owner of our common stock that, for United States federal income tax purposes, is not:

	•	a citizen or resident of the United States;

	•	a partnership or corporation created or organized in or under the laws of the United States or any state thereof, including the District of Columbia;

	•	an estate the income of which is subject to United States federal income taxation regardless of its source; or

	•	a trust if such trust validly elects to be treated as a United States person for United States federal income tax purposes or if (1) a court within the United States is able to exercise primary supervision over its administration and (2) one or more United States persons have the authority to control all of the substantial decisions of such trust.

If a partnership (or any other entity treated as a partnership for United States federal income tax purposes) holds our common stock, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. Such a partner or partnership should consult its tax advisor as to its tax consequences.

You should consult your own tax advisor with respect to the United States federal, state, local and foreign tax consequences of acquiring, owning and disposing of our common stock.

Distributions

Generally, but subject to the discussions below under ‘‘Status as United States Real Property Holding Corporation’’ and ‘‘Backup Withholding Tax and Information Reporting Requirements,’’ if you are a Non-U.S. Holder, distributions of cash or property (other than certain pro rata distributions of our common stock) paid to you will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable United States income tax treaty. In order to obtain the benefit of any applicable United States income tax treaty, you will have to file certain forms (e.g., Form W-8BEN). Such forms generally would contain your name and address and a certification that you are eligible for the benefits of such treaty.

Except as may be otherwise provided in an applicable United States income tax treaty, if you are a Non-U.S. Holder and conduct a trade or business within the United States, you generally will be taxed at ordinary United States federal income tax rates (on a net income basis) on dividends that are effectively connected with the conduct of such trade or business and such dividends will not be subject to the withholding described above. If you are a foreign corporation, you may also be subject to a 30% ‘‘branch profits tax’’ unless you qualify for a lower rate under an applicable United States income tax treaty. To claim an exemption from withholding because the income is effectively connected with a United States trade or business, you must provide a properly executed Form W-8ECI (or such successor form as the Internal Revenue Service designates) prior to the payment of dividends.

Sale or Exchange of Our Common Stock

Generally, but subject to the discussions below under ‘‘Status as United States Real Property Holding Corporation’’ and ‘‘Backup Withholding Tax and Information Reporting Requirements,’’ if you are a Non-U.S. Holder, you will not be subject to United States federal income or withholding tax on any gain realized on the sale or exchange of our common stock unless (1) such gain is effectively connected with your conduct of a trade or business in the United States or (2) if you are an individual, you are present in the United States for 183 days or more in the taxable year of such sale or exchange and certain other conditions are met.

Status as United States Real Property Holding Corporation

If you are a Non-U.S. Holder, under certain circumstances, gain recognized on the sale or exchange of, and certain distributions in excess of basis with respect to, our common stock would be subject to United States federal income tax, notwithstanding your lack of other connections with the United States, if we are or have been a ‘‘United States real property holding corporation’’ for United States federal income tax purposes at any time during the five-year period ending on the date of such sale or exchange (or distribution). We believe that we will not be classified as a United States real property holding corporation as of the date of this offering and do not expect to become a United States real property holding corporation.

Federal Estate Tax

Our common stock held by an individual at death, regardless of whether such individual is a citizen, resident or domiciliary of the United States, will be included in the individual's gross estate for United States federal estate tax purposes, subject to an applicable estate tax or other treaty, and therefore may be subject to United States federal estate tax.

Backup Withholding Tax and Information Reporting Requirements

United States backup withholding tax and information reporting requirements generally apply to certain payments to certain non-corporate holders of stock. The backup withholding tax rate currently is 28%.

If you are not a United States person, under current Treasury regulations, backup withholding and information reporting will not apply to distributions on our common stock to you, provided that

S-33

---

Table of Contents

we have received valid certifications meeting the requirements of the Code and neither we nor the payor has actual knowledge or reason to know that you are a United States person for purposes of such backup withholding tax requirements.

If provided by a beneficial owner, the certification must give the name and address of such owner, state that such owner is not a United States person, or, in the case of an individual, that such person is neither a citizen or resident of the United States, and must be signed by the owner under penalties of perjury. If provided by a financial institution, other than a financial institution that is a qualified intermediary, the certification must state that the financial institution has received from the beneficial owner the certificate set forth in the preceding sentence, set forth the information contained in such certificate (and include a copy of such certificate), and be signed by an authorized representative of the financial institution under penalties of perjury. Generally, the furnishing of the names of the beneficial owners of our common stock that are not United States persons and a copy of such beneficial owner's certificate by a financial institution will not be required where the financial institution is a qualified intermediary.

In the case of such payments made to a foreign simple trust, a foreign grantor trust or a foreign partnership, other than payments to a foreign simple trust, a foreign grantor trust or a foreign partnership that qualifies as a ‘‘withholding foreign trust’’ or a ‘‘withholding foreign partnership’’ within the meaning of such United States Treasury Regulations and payments to a foreign simple trust, a foreign grantor trust or a foreign partnership that are effectively connected with the conduct of a trade or business in the United States, the beneficiaries of the foreign simple trust, the persons treated as the owners of the foreign grantor trust or the partners of the foreign partnership, as the case may be, will be required to provide the certification discussed above, and the trust or partnership, as the case may be, will need to provide an appropriate intermediary certification form, in order to establish an exemption from backup withholding tax and information reporting requirements. Moreover, a payor may rely on a certification provided by a payee that is not a United States person only if such payor does not have actual knowledge or a reason to know that any information or certification stated in such certificate is incorrect.

The above description is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership and disposition of our common stock. You should consult your own tax advisor concerning the tax consequences of your particular situation.

 UNDERWRITING 

Lehman Brothers Inc. and Goldman, Sachs & Co. are acting as joint book-running managers and representatives of the underwriters. Under the terms of an underwriting agreement, which we will file as an exhibit to a current report on Form 8-K and incorporate by reference in this prospectus supplement and the accompanying prospectus, each of the underwriters named below has severally agreed to purchase from us the respective number of shares of common stock shown opposite its name below:

Underwriters				Number of Shares
Lehman Brothers Inc.					1,575,000
Goldman, Sachs & Co.					1,015,000
Citigroup Global Markets Inc.					525,000
HSBC Securities (USA) Inc.					175,000
RBC Capital Markets Corporation					175,000
Dundee Securities Inc.					35,000
Total					3,500,000

The underwriting agreement provides that the underwriters’ obligation to purchase shares of common stock depends on the satisfaction of the conditions contained in the underwriting agreement including:

	•	the obligation to purchase all of the shares of common stock offered hereby (other than those share of common stock covered by their option to purchase additional shares as described below), if any of the shares are purchased;

	•	the representations and warranties made by us to the underwriters are true;

	•	there is no material change in our business or in the financial markets; and

	•	we deliver customary closing documents to the underwriters.

Commissions and Expenses

The following table summarizes the underwriting discounts and commissions we will pay to the underwriters. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares. The underwriting fee is the difference between the initial price to the public and the amount the underwriters pay to us for the shares.

				No Exercise				Full Exercise
Per Share				$	1.686			$	1.686
Total				$	5,901,000			$	6,786,150

The representatives of the underwriters have advised us that the underwriters propose to offer the shares of common stock directly to the public at the public offering price on the cover of this prospectus supplement and to selected dealers, which may include the underwriters, at such offering price less a selling concession not in excess of $1.00 per share. After the offering, the representatives may change the offering price and other selling terms. In compliance with the guidelines of the National Association of Securities Dealers, Inc., the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any NASD member or independent broker-dealer will not exceed 8% of any offering pursuant to the prospectus and any applicable prospectus supplement, including this offering.

The expenses of the offering that are payable by us are estimated to be $1.1 million (excluding underwriting discounts and commissions).

Option to Purchase Additional Shares

We have granted the underwriters an option exercisable for 30 days after the date of the underwriting agreement, to purchase, from time to time, in whole or in part, up to an aggregate of

S-35

---

Table of Contents

525,000 shares at the public offering price less underwriting discounts and commissions. This option may be exercised if the underwriters sell more than 3,500,000 shares in connection with this offering. To the extent that this option is exercised, each underwriter will be obligated, subject to certain conditions, to purchase its pro rata portion of these additional shares based on the underwriter’s percentage underwriting commitment in the offering as indicated in the table at the beginning of this Underwriting section.

Lock-Up Agreements

We, all of our directors and executive officers and holders of more than 5% of our outstanding stock have agreed that, without the prior written consent of Lehman Brothers Inc., we will not directly or indirectly (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of common stock (including, without limitation, shares of common stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and shares of common stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for common stock, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock, (3) make any demand for or exercise any right or file or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of common stock or securities convertible, exercisable or exchangeable into common stock or any of our other securities, or (4) publicly disclose the intention to do any of the foregoing for a period of 90 days after the date of this prospectus supplement.

Lehman Brothers Inc., in its sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time with or without notice. When determining whether or not to release common stock and other securities from lock-up agreements, Lehman Brothers Inc. will consider, among other factors, the holder’s reasons for requesting the release, the number of shares of common stock and other securities for which the release is being requested and market conditions at the time.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

The representative may engage in stabilizing transactions, short sales and purchases to cover positions created by short sales, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of the common stock, in accordance with Regulation M under the Securities Exchange Act of 1934:

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

A short position involves a sale by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase in the offering, which creates the syndicate short position. This short position may be either a covered short position or a naked short position. In a covered short position, the number of shares involved in the sales made by the underwriters in excess of the number of shares they are obligated to purchase is not greater than the number of shares that they may purchase by exercising their option to purchase additional shares. In a naked short position, the number of shares involved is greater than the number of shares in their option to purchase additional shares. The underwriters may close out any short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to

S-36

---

Table of Contents

close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through their option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

Syndicate covering transactions involve purchases of the common stock in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result, the price of the common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on The New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In addition, neither we nor any of the underwriters make representation that the representatives will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Electronic Distribution

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by one or more of the underwriters or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the representatives on the same basis as other allocations.

Other than the prospectus in electronic format, the information on any underwriter's or selling group member's website and any information contained in any other website maintained by an underwriter or selling group member is not part of the prospectus or the registration statement of which this prospectus supplement and the accompanying prospectus forms a part, has not been approved or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied upon by investors.

Stamp Taxes

If you purchase shares of common stock offered in this prospectus supplement and the accompanying prospectus, you may be required to pay stamp taxes and other charges under the laws and practices of the country of purchase, in addition to the offering price listed on the cover page of this prospectus supplement and the accompanying prospectus.

Relationships

Certain of the underwriters and their related entities have engaged and may engage in commercial and investment banking transactions with us in the ordinary course of their business. They have received customary compensation and expenses for these commercial and investment banking transactions. Lehman Brothers Inc. acted as our financial advisor in a number of transactions, including our initial public offering and the recent issuance of $165.0 million senior secured notes pursuant to Rule 144A and Regulation S under the Securities Act to refinance the debt of our project subsidiary, OrCal Geothermal Inc. In connection with these transactions, Lehman Brothers Inc. received customary fees for such services and certain of its expenses were reimbursed.

Each underwriter has represented and agreed that:

	•	it is a person whose ordinary activities involve it in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of its business and (ii) it has not offered or sold and will not offer or sell the shares other than to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or as agent) for the purposes of their businesses or who it is reasonable to expect will acquire, hold, manage or dispose of investments (as principal or agent) for the purposes of their businesses where the issue of the shares would otherwise constitute a contravention of Section 19 of the Financial Services and Markets Act 2000 (‘‘FSMA’’) by the Company;

Table of Contents

ORMAT TECHNOLOGIES, INC.

Our Business

We are a leading vertically integrated company engaged in the geothermal and recovered energy power business. We design, develop, build, own and operate clean, environmentally friendly geothermal power plants, and we also design, develop and build, and plan to own and operate, recovered energy-based power plants, in each case using equipment that we design and manufacture. We conduct our business activities in two business segments. In our Electricity Segment, we develop, build, own and operate geothermal power plants in the United States and other countries and sell the electricity they generate. In our Products Segment, we design, manufacture and sell equipment for geothermal and recovered energy-based electricity generation, remote power units and other power generating units and provide services relating to the engineering, procurement, construction, operation and maintenance of geothermal and recovered energy power plants.

All of the projects that we currently own or operate produce electricity from geothermal energy sources. Geothermal energy is a clean and generally sustainable form of energy derived from the natural heat of the earth. Unlike electricity produced by burning fossil fuels, electricity produced from geothermal energy sources is produced without emissions of certain pollutants such as nitrogen oxide, and with far lower emissions of other pollutants such as carbon dioxide. Therefore, electricity produced from geothermal energy sources contributes significantly less to local and regional incidences of acid rain, and global warming than energy produced by burning fossil fuels. Geothermal energy is also an attractive alternative to other sources of energy as part of a national diversification strategy to avoid dependence on any one energy source or politically sensitive supply sources.

In addition to our geothermal energy power generation business, we have developed and continue to develop products that produce electricity from recovered energy or so-called ‘‘waste heat.’’ Recovered energy or waste heat represents residual heat that is generated as a by-product of gas turbine-driven compressor stations and in a variety of industrial processes, such as cement manufacturing, and is not otherwise used for any purpose. Such residual heat, that would otherwise be wasted, is captured in the recovery process and is used by recovered energy power plants to generate electricity without burning additional fuel and without emissions.

Our Executive Office

Our principal executive office is located at 980 Greg Street, Sparks, Nevada 89431. Our telephone number is (775) 356-9029.

 RATIOS OF EARNINGS TO FIXED CHARGES 

The following table sets forth our consolidated ratio of earnings to fixed charges for the periods indicated:

				Nine Months Ended September 30, 2005				Year Ended December 31,
								2004				2003				2002				2001				2000
Ratio of earnings to fixed charges				1.79				1.56				3.07				3.33				1.15				3.07

For purposes of this calculation, ‘‘earnings’’ refers to the sum of (1) pre-tax income from continuing operations, (2) fixed charges, (3) distributed income of equity investees; less interest capitalized.

‘‘Fixed charges’’ means the sum of (1) interest expensed and capitalized, (2) amortized premiums, discounts and capitalized expenses related to indebtedness and (3) an estimate of the interest within rental expense.

As of the date of this prospectus, we have no preferred shares outstanding, and consequently, our ratio of earnings to preferred share dividends and our ratio of earnings to fixed charges would be identical.

Table of Contents

DESCRIPTION OF DEBT SECURITIES WE MAY OFFER

The following summarizes certain material provisions of our senior debt indenture and our subordinated debt indenture that would be important to holders of debt securities. The following description is only a summary, may be supplemented in prospectus supplements, and is subject to, and qualified in its entirety by reference to, the terms and provisions of our senior debt indenture and our subordinated debt indenture which are exhibits to the registration statement which contains this prospectus.

Overview

We may issue senior or subordinated debt securities. Neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets. Thus, by owning a debt security, you are one of our unsecured creditors.

The senior debt securities will constitute part of our senior debt, will be issued under a senior debt indenture described below and will rank equally with all of our other unsecured and unsubordinated obligations.

The subordinated debt securities will constitute part of our subordinated debt, will be issued under a subordinated debt indenture described below and will be subordinate in right of payment to all of our ‘‘senior indebtedness’’, as defined in the subordinated debt indenture and as described below under ‘‘—Subordination Provisions—Senior Indebtedness’’. Neither indenture limits our ability to incur additional senior indebtedness.

In this prospectus, ‘‘debt securities’’ refers to both the senior debt securities and the subordinated debt securities.

We are a Holding Company

Because we are a holding company, our right to participate in any distribution of assets of any of our subsidiaries upon the subsidiary’s liquidation or reorganization or otherwise, is subject to the prior claims of its creditors, except to the extent we may be recognized as a creditor of that subsidiary. Accordingly, our obligations under the debt securities will be effectively subordinated to all existing and future indebtedness and liabilities of our subsidiaries, and you, as holders of debt securities should look only to our assets for payment thereunder.

Indentures and Trustees

Our senior debt securities and our subordinated debt securities are each governed by a document called an indenture, the senior debt indenture, in the case of the senior debt securities, and the subordinated debt indenture, in the case of the subordinated debt securities. Each indenture is a contract between us and Union Bank of California, N.A. (‘‘UBOC’’), which acts as trustee. The indentures are substantially identical, except for the provisions relating to subordination, which are included only in the subordinated debt indenture.

Reference to the indenture or the trustee with respect to any debt securities means the indenture under which those debt securities are issued and the trustee under that indenture.

The trustee has two main roles:

	•	First, the trustee can enforce your rights against us if we default on our obligations under the terms of the applicable indenture or the debt securities. There are some limitations on the extent to which the trustee acts on your behalf, described below under ‘‘—Default and Related Matters—Events of Default—Remedies if an Event of Default Occurs’’; and

	•	Second, the trustee performs administrative duties for us, such as sending you interest payments, transferring your debt securities to a new holder if you sell them and sending you certain notices.

Table of Contents

The indentures and their associated documents contain the full legal text of the matters summarized in this section. A copy of the form of senior debt indenture and the form of subordinated debt indenture appear as exhibits to our registration statement. See ‘‘Where You Can Find More Information’’ for information on how to obtain copies of the indentures.

Different Series of Debt Securities

We may issue as many distinct series of debt securities under either indenture as we wish. The provisions of each indenture allow us not only to issue debt securities with terms different from those of debt securities previously issued under that indenture, but also to ‘‘reopen’’ a previously issued series of debt securities and issue additional debt securities of that series.

Because this section is a summary, it does not describe every aspect of the debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the indentures, including definitions of some of the terms used in the indentures. We discuss only the more important terms in this prospectus. Whenever we refer to the defined terms of the indentures in this prospectus or in a prospectus supplement, those defined terms are incorporated by reference here or in the prospectus supplement. You must look to the indentures for the most complete description of what we describe in summary form in this prospectus.

This summary also is subject to and qualified by reference to the description of the particular terms of your series described in the prospectus supplement. Those terms may vary from the terms described in this prospectus. The prospectus supplement will describe any differences with the material terms summarized here. The prospectus supplement relating to each series of debt securities will be attached to the front of this prospectus. There may also be a further prospectus supplement, known as a pricing supplement, which contains the precise terms of debt securities you are offered.

Tax Treatment of Original Issue Discount and Other Debt Securities

We may issue debt securities as original issue discount securities, which are securities that are offered and sold at a substantial discount to their stated principal amount and which may provide that, upon redemption or acceleration of maturity, an amount less than their principal amount will be payable. The prospectus supplement relating to original issue discount securities will describe the U.S. federal income tax consequences and other special considerations applicable to them. We may also issue debt securities as indexed securities or securities denominated in foreign currencies, currency units or composite currencies, which may trigger special U.S. federal income tax, accounting and other consequences, all as described in more detail in the prospectus supplement relating to any of the particular debt securities.

A Prospectus Supplement and a Supplemental Indenture (If Required) Will Describe the Specific Terms of a Series of Debt Securities

The specific financial, legal and other terms particular to a series of debt securities will be described in the prospectus supplement, supplemental indenture (if required) and the pricing supplement relating to the series. The prospectus supplement and supplemental indenture (if required) relating to a series of debt securities will describe the following terms of the series:

Those terms may vary from the terms described here. Accordingly, this summary also is subject to and qualified by reference to the description of the terms of the series described in the applicable prospectus supplement and any supplemental indenture.

Legal Ownership

Street Name and Other Indirect Holders

We generally will not recognize investors who hold debt securities in accounts at banks or brokers, i.e. in ‘‘street name’’, as legal holders of debt securities. Instead, we would recognize only the bank or broker, or the financial institution the bank or broker uses to hold its debt securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to do so. If you hold debt securities in street name, you are responsible for checking with your own institution to find out:

	•	how it handles securities payments and notices;

	•	how it would handle a request for the holders’ consent if ever required;

	•	whether it imposes fees or charges;

	•	how it would handle voting if ever required;

	•	whether and how you can instruct it to send you debt securities registered in your own name so you can be a direct holder as described below; and

	•	how it would pursue rights under the debt securities if there were a default or other event triggering the need for holders to act to protect their interests.

Direct Holders

Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to persons or entities who are the direct holders of debt securities, which means those who are registered as holders of debt securities. As noted above, we will not have obligations to you if you hold in street name or through other indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities as described below. For example, once we make payment to the registered holder, we will have no further responsibility for that payment even if that registered holder is legally required to pass the payment along to you as a street name holder but does not do so.

Global Securities

What Is a Global Security?    A global security is a special type of indirectly held security, as described above under ‘‘—Legal Ownership—Street Name and Other Indirect Holders’’.

If we choose to issue debt securities in the form of global securities, the ultimate beneficial owners can only be indirect holders. We do this by requiring that the global security be registered in the name of a financial institution we select and by requiring that the debt securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below occur. The financial institution that acts as the sole direct holder of the global security is called the depositary.

Any person wishing to own a debt security included in the global security must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the depositary. The prospectus supplement will indicate whether your series of debt securities will be issued only in the form of global securities.

Special Investor Considerations for Global Securities. As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution

10

Table of Contents

and of the depositary, as well as general laws relating to securities transfers. We will not recognize this type of investor as a registered holder of debt securities and instead deal only with the depositary that holds the global security.

If you are an investor in debt securities that are issued only in the form of global securities, you should be aware that:

	•	you cannot get debt securities registered in your own name except in certain limited circumstances as described below under ‘‘—Legal Ownership—Global Securities—Special Situations When Global Security Will Be Cancelled’’;

	•	you cannot receive physical certificates for your interest in the debt securities;

	•	you will be a street name holder and must look to your own bank or broker for payments on the debt securities and protection of your legal rights relating to the debt securities. See ‘‘—Legal Ownership—Street Name and Other Indirect Holders’’;

	•	you may not be able to sell interests in the debt securities to some insurance companies and other institutions that are required by law to own their securities in the form of physical certificates;

	•	the depositary’s policies will govern payments, transfers, exchange and other matters relating to your interest in the global security. We and the trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership interests in the global security. We and the trustee also do not supervise the depositary in any way; and

	•	the depositary will require that interests in a global security be purchased or sold within its system using same-day funds for settlement.

Special Situations When Global Security Will Be Cancelled. In a few special situations described below, the global security will be cancelled and interests in it will be exchanged for physical certificates representing debt securities. After that exchange, the choice of whether to hold debt securities directly or in street name will be up to you. You must consult your own bank or broker to find out how to have your interests in debt securities transferred to your own name, so that you will be a direct holder.

The special situations for cancellation of a global security are:

	•	when the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary;

	•	when we notify the trustee that we wish to cancel (subject to the procedures of the depositary) the global security; or

	•	when an event of default on the debt securities has occurred and has not been cured.

Defaults are discussed later under ‘‘—Default and Related Matters’’.

The prospectus supplement may also list additional situations for cancellation of a global security that would apply only to the particular series of debt securities covered by the prospectus supplement. When a global security is cancelled, the depositary, not we nor the trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.

In the remainder of this description, ‘‘you’’ means direct holders and not street name or other indirect holders of debt securities. Indirect holders should read the previous subsection entitled ‘‘—Legal Ownership—Street Name and Other Indirect Holders’’.

Overview of the Remainder of this Description

The remainder of this description summarizes:

	•	additional mechanics relevant to our debt securities under normal circumstances, such as how you transfer ownership and where we make payments;

11

---

Table of Contents

	•	your rights under several special situations, such as if we merge with another company or if we want to change a term of the debt securities;

	•	subordination provisions in the subordinated debt indenture that may prohibit us from making payments on those securities;

	•	a particular series of debt securities may have additional, fewer or different restrictive covenants;

	•	situations in which we may invoke the provisions relating to defeasance;

	•	your rights if we default or experience other financial difficulties;

	•	conversion or exchange rights;

	•	redemption;

	•	reopenings; and

	•	our relationship with the trustee.

Additional Mechanics

Form, Exchanges and Transfer of our Debt Securities

Form. The debt securities will be issued:

	•	only in fully registered form;

	•	without interest coupons; and

	•	unless otherwise indicated in the applicable prospectus supplement and any supplemental indenture, in denominations that are integral multiples of $1,000.

You may have your debt securities broken into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. This is called an exchange. You may not exchange your debt securities for securities of a different series or having different terms, unless your prospectus supplement says you may.

Exchanges and Transfers. You may exchange or transfer debt securities at the office of the trustee. You may also replace lost, stolen, destroyed or mutilated debt securities at that office. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may change this appointment to another entity or perform the service ourselves. The entity performing the role of maintaining the list of registered direct holders is called the ‘‘security registrar’’. It will also register transfers of the debt securities.

You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

If we designate additional transfer agents, they will be named in the prospectus supplement. We may cancel the designation of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

If the debt securities are redeemable and we redeem less than all of the debt securities of a particular series, we may block the transfer or exchange of debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of debt securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security being partially redeemed.

Payment and Paying Agents

We will pay interest to you if you are a direct holder listed in the trustee’s records at the close of business on a particular day, called the regular record date, in advance of each due date for interest,

12

---

Table of Contents

even if you no longer own the debt security on the interest due date. The regular record date is usually about two weeks in advance of the interest due date and is stated in the prospectus supplement. Holders buying and selling debt securities must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the one who is the registered holder on the regular record date. The most common manner is to adjust the sales price of the debt securities to prorate interest fairly between buyer and seller.

We will pay interest, principal and any other money due on the debt securities at the office as we may designate at various times. You must make arrangements to have your payments picked up at or wired from that office. We may also choose to pay interest by mailing checks.

If you are a street name holder or other indirect holder, you should consult your bank or your broker for information on how you will receive payments.

We may also arrange for additional payment offices, and may cancel or change these offices, including our use of the trustee’s corporate trust office. These offices are called paying agents. We may also choose to act as our own paying agent. We must notify you of changes in the paying agents for any particular series of debt securities.

Notices

We and the trustee will send notices regarding the debt securities only to direct holders, using their addresses as listed in the trustee’s records.

Unclaimed Payments

Regardless of whom acts as paying agent, all money paid by us to a paying agent that remains unclaimed at the end of one year after the amount is due to direct holders will be repaid to us. After that one-year period, you may look only to us for payment and not to the trustee, any other paying agent or anyone else.

Special Situations

Mergers and Similar Events

We are generally permitted to consolidate or merge with another company or firm. We are also permitted to sell or lease substantially all of our assets to another company or firm, or to buy or lease substantially all of the assets of another company or firm. However, we may not take any of these actions unless the following conditions, among others, are met:

	•	Where we merge out of existence or sell or lease substantially all our assets, the other company or firm must be a corporation, partnership or trust organized under the laws of a State of the United States or the District of Columbia or under United States federal law, and it must agree to be legally responsible for the debt securities.

	•	The consolidation, merger, sale of assets or other transaction must not cause a default on the debt securities, and we must not already be in default, unless the transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured. A default for this purpose would also include any event that would be an event of default if the requirements for giving us notice of our default or our default having to exist for a specific period of time were disregarded.

	•	Where the consolidation, merger, sale of assets or other transaction would cause some of our property to become subject to a mortgage or other legal mechanism giving lenders preferential rights in that property over other lenders, we or the successor company must take such steps necessary to secure the debt securities equally and ratably with all indebtedness secured thereby.

Modification and Waiver

There are four types of changes we can make to either indenture and the applicable series of debt securities issued under that indenture.

13

---

Table of Contents

Changes Requiring Your Approval. First, there are changes that cannot be made to your debt securities without your specific approval. Following is a list of these types of changes:

	•	change to the payment due date of the principal or interest on a debt security;

	•	reduction of any amounts due on a debt security;

	•	reduction of the amount of principal payable upon acceleration of the maturity of a debt security, including the amount payable on an original issue discount security, following a default;

	•	change to the place or currency of payment on a debt security;

	•	impairment of your right to sue for payment of any amount due on your debt security;

	•	impairment of any right that you may have to exchange or convert the debt security for or into other securities or property;

	•	reduction of the percentage of direct holders of debt securities whose consent is needed to modify or amend the applicable indenture;

	•	reduction of the percentage of direct holders of debt securities whose consent is needed to waive our compliance with certain provisions of the applicable indenture or to waive certain defaults; and

	•	modification of any other aspect of the provisions dealing with modification and waiver of the applicable indenture.

Changes Requiring a Majority Vote. The second type of change to a particular indenture and the debt securities is the kind that requires a vote in favor by direct holders of debt securities owning a majority of the principal amount of each series affected thereby. Most changes, including waivers, as described below, fall into this category, except for changes noted above as requiring the approval of the holders of each security affected thereby, and, as noted below, changes not requiring approval.

Each indenture provides that a supplemental indenture which changes or eliminates any covenant or other provision of the applicable indenture which has expressly been included solely for the benefit of one or more particular series of securities, or which modifies the rights of the holders of securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the applicable indenture of the holders of securities of any other series.

Changes Not Requiring Approval. The third type of change does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes referenced in our indentures that would not adversely affect holders of the debt securities.

Changes by Waiver Requiring a Majority Vote. Fourth, we need the approval of direct holders of senior debt securities owning a majority of the principal amount of the particular series affected to obtain a waiver of certain of the restrictive covenants. We also need such majority approval to obtain a waiver of any past default, except a default of the payment of principal, premium (if any) or interest, as described in the first two categories described below under ‘‘—Default and Related Matters—Events of Default’’.

Modification of Subordination Provisions. In addition, we may not modify the subordination provisions of the subordinated debt indenture in a manner that would adversely affect the outstanding subordinated debt securities of any one or more series in any material respect without the consent of the direct holders of a majority in aggregate principal amount of each affected series.

Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a debt security:

	•	for original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the debt securities were accelerated to that date because of a default;

	•	for debt securities whose principal amount is not known, for example, because it is based on an index, we will use a special rule for that debt security described in the applicable prospectus supplement; or

14

---

Table of Contents

	•	for debt securities denominated in one or more foreign currencies, currency units or composite currencies, we will use the U.S. dollar equivalent.

Debt securities will not be considered outstanding, and therefore will not be eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption. Debt securities will also not be eligible to vote if they have been fully defeased as described below under ‘‘—Defeasance—Full Defeasance’’.

We will generally be entitled to set any day as a record date for the purpose of determining the direct holders of outstanding debt securities that are entitled to vote or take other action under the applicable indenture. In some circumstances, the trustee will be entitled to set a record date for action by direct holders. If we or the trustee set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are direct holders of outstanding securities of that series on the record date and must be taken within 90 days following the record date.

If you are a street name holder or other indirect holder, you should consult your bank or broker for information on how you may grant or deny approval if we seek to change an indenture or the debt securities or request a waiver.

Subordination Provisions

Direct holders of subordinated debt securities must recognize that contractual provisions in the subordinated debt indenture may prohibit us from making payments on those securities. Subordinated debt securities are subordinate and junior in right of payment, to the extent and in the manner stated in the subordinated debt indenture, to all of our senior indebtedness, as defined in the subordinated debt indenture, including all debt securities we have issued and will issue under the senior debt indenture.

Senior Indebtedness

Under the subordinated debt indenture, ‘‘senior indebtedness’’ includes all of our obligations to pay principal, premium, if any, interest, penalties, fees and other charges:

	•	for borrowed money;

	•	in the form of or evidenced by securities, notes, debentures, bonds or similar instruments, including obligations incurred in connection with our purchase of property, assets or businesses;

	•	under capital leases;

	•	under letters of credit and bankers’ acceptances;

	•	issued or assumed in the form of a deferred purchase price of property or services, such as master leases;

	•	under swaps and other hedging arrangements; and

	•	pursuant to our guarantee of another entity’s obligations and all dividend obligations guaranteed by us.

The following types of our indebtedness will not rank senior to the subordinated debt securities:

	•	indebtedness incurred in the form of trade accounts payable or accrued liabilities arising in the ordinary course of business, including liabilities under reinsurance and retrocessional agreements;

	•	indebtedness which, by its terms, expressly provides that it does not rank senior to the subordinated debt securities;

	•	indebtedness we owe to a subsidiary of ours; and

	•	indebtedness we owe to any trust or a trustee of such trust, partnership or other entity affiliated with us, which is our financing vehicle unless the terms of that indebtedness expressly provide otherwise.

15

Table of Contents

Payment Restrictions on our Subordinated Debt

The subordinated debt indenture provides that, unless all principal of and any premium or interest on the senior indebtedness has been paid in full, no payment or other distribution may be made in respect of any subordinated debt securities in the following circumstances:

	•	in the event of any insolvency or bankruptcy proceedings, or any receivership, liquidation, reorganization, assignment for creditors or other similar proceedings or events involving us or our assets; or

	•	(a) in the event and during the continuation of any default in the payment of principal, premium, if any, or interest on any senior indebtedness beyond any applicable grace period, (b) in the event that any event of default with respect to any senior indebtedness has occurred and is continuing, permitting the direct holders of that senior indebtedness (or a trustee) to accelerate the maturity of that senior indebtedness, whether or not the maturity is in fact accelerated (unless, in the case of either (a) or (b), the payment default or event of default has been cured or waived or ceased to exist and any related acceleration has been rescinded), or (c) in the event that any judicial proceeding is pending with respect to a payment default or event of default described in (a) or (b).

If the trustee under the subordinated debt indenture or any direct holders of the subordinated debt securities receive any payment or distribution that is prohibited under the subordination provisions, then the trustee or the direct holders will have to repay that money to the direct holders of the senior indebtedness.

Even if the subordination provisions prevent us from making any payment when due on the subordinated debt securities of any series, we will be in default on our obligations under that series if we do not make the payment when due. This means that the trustee under the subordinated debt indenture and the direct holders of that series can take action against us, but they will not receive any money until the claims of the direct holders of senior indebtedness have been fully satisfied.

Restrictive Covenants

General

We have made certain promises in each indenture called covenants where, among other things, we promise to maintain our corporate existence and all licenses and material permits necessary for our business.

We will describe any additional restrictive covenants for any series of debt securities in the relevant prospectus supplement.

Defeasance

The following discussion of full defeasance and covenant defeasance will apply to your series of debt securities only if we choose to have them apply to that series. If we do so choose, we will state that in the applicable prospectus supplement.

Full Defeasance

We can legally release ourselves from any payment or other obligations on the debt securities, called full defeasance, if we put in place the following arrangements for you to be repaid:

	•	we must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities money or U.S. government or U.S. government agency notes or bonds or a combination thereof that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates;

	•	there must be a change in current U.S. federal income tax law or a U.S. Internal Revenue Service ruling that lets us make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt

16

---

Table of Contents

		securities ourselves. (Under current federal tax law, the deposit and our legal release from the debt securities would be treated as though we took back your debt securities and gave you your share of the cash and notes or bonds deposited in trust. In that event, you could recognize gain or loss on the debt securities you give back to us.);

	•	we must deliver to the trustee a legal opinion of our counsel confirming the tax law change described above and that under current federal income tax law we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves;

	•	the full defeasance must not result in a breach or violation of, or constitute a default under the applicable indenture or any other agreement or instrument to which we are a party or by which we are bound;

	•	no event of default or event which with notice or lapse of time or both would become an event of default with respect to the debt securities to be defeased may occur and be continuing on the date of such deposit (other than an Event of Default resulting from the incurrence of indebtedness all or a portion of the proceeds of which will be used to defease the debt securities concurrently with such incurrence) and no bankruptcy proceeding may occur and be continuing at any time during the period ending on the 90th day after the date of such deposit or, if longer, ending on the day following the expiration of the longest preference period applicable to us in respect of such deposit; and

	•	in the case of the subordinated debt securities, the following requirements must also be met:

	•	no event or condition may exist that, under the provisions described above under ‘‘—Subordination Provisions’’, would prevent us from making payments of principal, premium or interest on those subordinated debt securities on the date of the deposit referred to above or during the 90 days after that date; and

	•	we must deliver to the trustee an opinion of counsel to the effect that (a) the trust funds will not be subject to any rights of direct holders of senior indebtedness and (b) after the 90-day period referred to above, the trust funds will not be subject to any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, except that if a court were to rule under any of those laws in any case or proceeding that the trust funds remained our property, then the relevant trustee and the direct holders of the subordinated debt securities would be entitled to some enumerated rights as secured creditors in the trust funds.

If we accomplish full defeasance, as described above, you will have to rely solely on the trust deposit for repayment on the debt securities. In addition, in the case of subordinated debt securities, the provisions described above under ‘‘—Subordination Provisions’’ would not apply. You could not look to us for repayment in the event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

Covenant Defeasance

Under current U.S. federal income tax law, we can make the same type of deposit described above and be released from the restrictive covenants listed below in the debt securities without causing tax consequences to you. This type of release is called covenant defeasance. If we ever did accomplish covenant defeasance, you would lose the protection of those restrictive covenants but would gain the protection of having money and securities set aside in trust to repay the debt securities. In order to achieve covenant defeasance, we must do the following:

	•	we must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates;

17

---

Table of Contents

	•	we must deliver to the trustee a legal opinion of our counsel confirming that under current federal income tax law we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves;

	•	the covenant defeasance must not result in a breach or violation of, or constitute a default under the applicable indenture or any other agreement or instrument to which we are a party or by which we are bound; and

	•	no event of default or event which with notice or lapse of time or both would become an event of default with respect to the debt securities to be defeased will have occurred and be continuing on the date of such deposit (other than an Event of Default resulting from the incurrence of indebtedness all or a portion of the proceeds of which will be used to defease the debt securities concurrently with such incurrence) and no bankruptcy proceeding will have occurred and be continuing at any time during the period ending on the 90th day after the date of such deposit or, if longer, ending on the day following the expiration of the longest preference period applicable to us in respect of such deposit.

If we accomplish covenant defeasance, the following provisions, among others, of the indentures and the debt securities would no longer apply:

	•	any covenants applicable to the series of debt securities and described in the prospectus supplement;

	•	the condition regarding the treatment of liens when we merge or engage in similar transactions, as described above under ‘‘—Special Situations—Mergers and Similar Events’’; and

	•	the events of default relating to breach of covenants, described below under ‘‘—Default and Related Matters—Events of Default—What Is an Event of Default?’’.

In addition, in the case of subordinated debt securities, the provisions described above under ‘‘—Subordination Provisions’’ will not apply if we accomplish covenant defeasance.

If we accomplish covenant defeasance, you could still look to us for repayment of the debt securities if there were a shortfall in the trust deposit. In fact, if one of the remaining events of default occurs, such as our bankruptcy, and the debt securities become immediately due and payable, there may be a shortfall in the trust deposit. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Default and Related Matters

The debt securities are not secured by any of our property or assets. Accordingly, your ownership of debt securities means that you are one of our unsecured creditors. The senior debt securities are not subordinated to any of our debt obligations and therefore they rank equally with all of our other unsecured and unsubordinated indebtedness. The subordinated debt securities are subordinate and junior in right of payment to all of our senior indebtedness, as defined in the subordinated debt indenture and as described above under ‘‘—Subordination Provisions’’.

Events of Default

You will have special rights if an event of default occurs and is not cured or waived, as described below in this subsection.

What Is an Event of Default?    The term ‘‘event of default’’ means any of the following:

	•	we do not pay the principal or any premium on a debt security on its due date;

	•	we do not pay interest on a debt security within 30 days of its due date;

	•	we do not deposit money into a separate custodial account, known as a sinking fund, when such deposit is due, if we agree to maintain any such sinking fund;

18

---

Table of Contents

	•	we remain in breach of any covenant or warranty of the applicable indenture for 60 days after we receive a notice of default stating we are in breach and requiring us to remedy that default or breach; the notice must be sent by either the trustee or direct holders of at least 25% of the principal amount of the outstanding debt securities of the affected series;

	•	we default under any bond, debenture, note or other evidence of indebtedness for money borrowed by us having an aggregate principal amount outstanding of at least $50,000,000, or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by us having an aggregate principal amount outstanding of at least $50,000,000, whether such indebtedness now exists or shall hereafter be created;

	•	we file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur; or

	•	any other event of default described in the prospectus supplement occurs.

Remedies If an Event of Default Occurs. If an event of default has occurred and has not been cured or waived, the trustee or the direct holders of 25% in principal amount of the debt securities of the affected series may declare the entire principal amount, or, in the case of original issue discount securities, the portion of the principal amount that is specified in the terms of the affected debt security, of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. However, a declaration of acceleration of maturity may be canceled by the direct holders of at least a majority in principal amount of the debt securities of the affected series. If you are the holder of a subordinated debt security, all remedies available to you upon the occurrence of an event of default under the subordinated debt indenture will be subject to the restrictions on the subordinated debt securities described above under ‘‘—Subordination Provisions’’, subject to applicable law and certain terms of the indenture.

You should refer to the prospectus supplement relating to any series of debt securities that are original issue discount securities for the particular provisions relating to acceleration of the maturity of a portion of the principal amount of original issue discount securities upon the occurrence of an event of default and its continuation.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indentures at the request of any holders unless the direct holders offer the trustee reasonable protection from expenses and liability, called an indemnity. If reasonable indemnity is provided, the direct holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority direct holders may also direct the trustee in performing any other action under the applicable indenture with respect to the debt securities of that series.

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

	•	you must give the trustee written notice that an event of default has occurred and remains uncured;

	•	the direct holders of 25% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default, and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action;

	•	the trustee must have not received from direct holders of a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with the written notice; and

	•	the trustee must have not taken action for 60 days after receipt of the above notice and offer of indemnity.

19

---

Table of Contents

You are, however, entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date.

If you are a street name holder or other indirect holder, you should consult your bank or your broker for information on how to give notice or direction to or make a request of the trustee and to make or cancel a declaration of acceleration.

We will furnish to the trustee every year a written statement of certain of our officers certifying that to their knowledge we are in compliance with the applicable indenture and the debt securities issued under it, or else specifying any default.

Conversion or Exchange

The terms on which debt securities of any series are convertible into or exchangeable for shares of our common stock or other securities or property of ours or of third parties will be set forth in the applicable prospectus supplement and any supplemental indenture. These terms will include:

	•	the conversion or exchange price, or manner for calculating such a price;

	•	the exchange or conversion period; and

	•	whether the conversion or exchange is mandatory, at the option of the holder, or at our option.

The terms may also include calculations pursuant to which the number of shares of our or a third party’s common stock or other securities or property to be received by the holders of debt securities would be determined according to the market price of our common stock or other securities or property of ours or of third parties as of a time stated in the prospectus supplement. The conversion or exchange price of any debt securities of any series that is convertible into our common stock may be adjusted for any share dividends, bonus issues, stock splits, subdivisions, reclassification, combinations or similar transactions, in each case as we may describe in the applicable prospectus supplement.

Redemption

Unless we state otherwise in an applicable prospectus supplement and any supplemental indenture, debt securities will not be subject to any sinking fund.

If we issue redeemable debt securities, the dates and terms on which those securities are mandatorily or optionally redeemable will be set forth in the applicable prospectus supplement and any supplemental indenture. If a series of debt securities is redeemable, the redemption price for any debt security that we redeem will equal 100% of the principal amount plus any accrued and unpaid interest up to, but excluding, the redemption date, unless otherwise specified in the applicable prospectus supplement and any supplemental indenture.

Reopenings

The provisions of each indenture allow us to ‘‘reopen’’ a series of our debt securities. This means that we can increase the principal amount of a series of our debt securities by selling additional debt securities with the same terms. We may do so without notice to the existing holders of debt securities of that series. However, any new debt securities of this kind may begin to bear interest at a different date and they may be offered or sold at prices that are different from the original offering or sale of the same series of debt securities depending on then prevailing market conditions.

Governing Law; Submission to Jurisdiction

The indentures are, and the debt securities will be, governed by and construed in accordance with the laws of the State of New York. We will submit to the jurisdiction of the United States federal and New York State courts located in the Borough of Manhattan, City and State of New York for purposes of all legal actions and proceedings instituted in connection with our debt securities and the indentures.

Our Relationship with the Trustee

The trustee under our senior indenture and our subordinated indenture is UBOC. We and our subsidiaries maintain banking and other service relationships with UBOC.

DESCRIPTION OF COMMON STOCK WE MAY OFFER

The following summarizes certain material provisions of our Certificate of Incorporation, By-laws and applicable provisions of Delaware law that are important to holders of shares of our common stock. The following description is only a summary, may be supplemented in prospectus supplements and is subject to, and qualified in its entirety by reference to, the terms and provisions of our Certificate of Incorporation and By-laws and other agreements which are exhibits to the registration statement which contains this prospectus.

Authorized Capital

Our Certificate of Incorporation provides that our authorized capital stock will consist of an aggregate number of 200,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, of which our board of directors has designated 500,000 shares as Series A Junior Participatory Preferred Stock for issuance in connection with the exercise of our preferred share purchase rights. See ‘‘—Provisions of Our Certificate of Incorporation and By-laws, Rights Plan and Delaware Law that May Have an Anti-Takeover Effect-Rights Plan’’ below. As of January 12, 2006, 31,562,496 shares of our common stock were issued and outstanding, of which 24,374,996 were owned by our parent company, Ormat Industries, Ltd. In addition, 247,500 shares of our common stock have been reserved for issuance upon exercise of outstanding options and 1,002,500 shares of our common stock have been reserved for additional issuance under our 2004 Incentive Compensation Plan.

Common Stock

Voting. The holders of our common stock are entitled to one vote for each outstanding share of common stock owned by that stockholder on every matter properly submitted to the stockholders for their vote. Stockholders are not entitled to vote cumulatively for the election of directors.

Dividend Rights. Subject to the dividend rights of the holders of any outstanding series of preferred stock, holders of our common stock are entitled to receive ratably such dividends and other distributions of cash or any other right or property as may be declared by our board of directors out of our assets or funds legally available for such dividends or distributions.

Liquidation Rights. In the event of any voluntary of involuntary liquidation, dissolution or winding up of our affairs, holders of our common stock would be entitled to share ratably in our assets that are legally available for distribution to stockholders after payment of liabilities. If we have any preferred stock outstanding at such time, holders of the preferred stock may be entitled to distribution and/or liquidation preferences. In either such case, we must pay the applicable distribution to the holders of our preferred stock before we may pay distributions to the holders of our common stock.

Conversion, Redemption and Preemptive Rights. Holders of our common stock have no conversion, redemption, preemptive, subscription or similar rights.

Preferred Stock

As noted above, the rights, preferences and privileges of holders of our common stock may be affected by the rights, preferences and privileges granted to holders of preferred stock. For this reason, you should be aware that our Certificate of Incorporation authorizes our board of directors, subject to limitations prescribed by law, to issue up to 5,000,000 shares of preferred stock in one or more series without further stockholder approval. The board will have discretion to determine the rights, preferences, privileges and restrictions of, including, without limitation, voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of, and to fix the number of shares of, each series of our preferred stock.

Our board of directors has designated 500,000 shares of our preferred stock as Series A Junior Participatory Preferred Stock for issuance in connection with the exercise of our preferred share

purchase rights. Although our board of directors has no intention at the present time of doing so, it could authorize the issuance of shares of preferred stock with terms and conditions that could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common stock or otherwise be in their best interest. See ‘‘—Rights Plan’’ below.

Limitations on Directors’ and Officers’ Liability

Section 102(b)(7) of the Delaware General Corporation Law, which we refer to as the "DGCL", permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for:

	•	any breach of his or her duty of loyalty to us or our stockholders;

	•	acts or omissions not in good faith which involve intentional misconduct or a knowing violation of law;

	•	the payment of dividends or the redemption or purchase of stock in violation of Delaware law; or

	•	any transaction from which the director derived an improper personal benefit.

As permitted by Section 102(b)(7) of the DGCL, our Certificate of Incorporation contains a provision that provides for such limitation of liability. The effect of this provision is to restrict our rights and the rights of our stockholders in derivative suits to recover monetary damages against a director for breach of fiduciary duty as a director.

Section 145 of the DGCL provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent of the Company, subject to certain limitations. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise. As permitted by Section 145 of the DGCL, our By-laws provide that the Company has the power, under specified circumstances, to indemnify its directors, officers, employees and agents in connection with actions, suits or proceedings brought against them by a third party or in the right of the Company, by reason of the fact that they were or are such directors, officers, employees or agents, against expenses incurred in any such action, suit or proceeding.

In addition, the Company has entered into separate indemnification agreements with certain of its directors and officers that provide indemnification to its directors and officers under certain circumstances for acts or omissions, which may not be covered by directors and officers liability insurance, and may, in some cases, be broader than the specific indemnification provisions contained under Delaware law. The Company also maintains standard policies of insurance under which coverage is provided to its directors and officers to insure against certain liabilities that such persons may incur in their capacities as directors and officers of the Company.

To the extent that our directors, officers and controlling persons are indemnified under the provisions contained in our Certificate of Incorporation, Delaware law or contractual arrangements against liabilities arising under the Securities Act, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Issuance of Stock

No shares of stock of the Company will be issued unless authorized by our board of directors, which authorization will include the maximum number of shares to be issued and the consideration to be received for each share.

Provisions of Our Certificate of Incorporation and By-laws, Rights Plan and Delaware Law that May Have an Anti-Takeover Effect

Certificate of Incorporation and By-laws

Certain provisions in our Certificate of Incorporation and By-laws summarized below may be deemed to have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests, including attempts that might result in a premium being paid over the market price for the shares held by stockholders.

Classified Board of Directors. Our Certificate of Incorporation provides that the number of directors is fixed by our board of directors. Other than directors elected by the holders of any series of preferred stock or any other series or class of stock (except common stock), our directors are divided into three classes. Each class consists as nearly as possible of an equal number of directors. Currently, the terms of office for the three classes of directors expire, respectively, at our annual meetings in 2006, 2007 and 2008. The term of the successors of each class of directors expires three years from the year of election. Directors elected by stockholders at an annual meeting of stockholders will be elected by a plurality of all votes cast. To amend or repeal the provisions providing for our classified board of directors in our Certificate of Incorporation and By-laws, the affirmative vote of the holders of at least 75% of the then outstanding shares of capital stock entitled to vote is required.

Special Meetings. Our Certificate of Incorporation and By-laws provide that a special meeting of stockholders may be called only by the Chairman of the Board, the President, our board of directors, the holders of not less than a majority of all of the outstanding shares of the corporation entitled to vote at the meeting or, at any time that Ormat Industries (or a certain transferee of Ormat Industries) owns at least 20% of the then outstanding shares of our common stock, by Ormat Industries (or such transferee). Stockholders are not permitted to call, or to require that the board of directors call, a special meeting of stockholders. Moreover, the business permitted to be conducted at any special meeting of stockholders is limited to the business brought before the meeting pursuant to the notice of the meeting given by us. Our By-laws establish an advance notice procedure for stockholders to nominate candidates for election as directors or to bring other business before meetings of our stockholders.

The foregoing proposed provisions of our Certificate of Incorporation and By-laws could discourage potential acquisition proposals and could delay or prevent a change in control. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and in the policies formulated by the board of directors and to discourage certain types of transactions that may involve an actual or threatened change of control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our common stock that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.

Rights Plan

Pursuant to our rights agreement with American Stock Transfer & Trust Company, as rights agent, each holder of our common stock has the right (which we refer to, collectively, as the "rights") to purchase one one-hundredth of a share of Series A Junior Participating Preferred Stock for each share of common stock owned by each such holder for $80.00, subject to adjustment. Our rights initially trade with, and are inseparable from, our common stock. Our rights are evidenced only by certificates that represent shares of our common stock. New rights will accompany any new shares of common stock we issue until the date on which the rights are distributed as described below. The rights will generally become exercisable ten days following a public announcement that a person or group of affiliated or associated persons (which we refer to as an "acquiring person") has acquired beneficial ownership of 15% or more of the voting power of all of our outstanding capital stock or ten

23

---

Table of Contents

business days, or such later date as may be determined by our board of directors prior to such time as any person or group becomes an acquiring person, following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of which would result in the beneficial ownership by a person or group of 15% or more of the voting power of all of our outstanding capital stock. In the event that, at any time after a person has become an acquiring person, we are acquired in a merger or other business combination transaction or 50% or more of our consolidated assets or earning power is sold, proper provision will be made so that each holder of rights will thereafter have the right to receive, upon the exercise thereof, at the then current exercise price of the rights, that number of shares of common stock of the acquiring company which at the time of such transaction will have a market value of two times the exercise price of the rights. In the event that any person becomes an acquiring person, proper provision shall be made so that each holder of rights, other than the rights beneficially owned by the acquiring person, which will thereafter be void, will have the right to receive upon exercise, instead of shares of Series A Junior Participating Preferred Stock, that number of shares of common stock having a market value of two times the exercise price of the rights. The rights have the right to vote once exercised, expire in 2014 and may be redeemed by us, at the discretion of our board of directors, in whole, but not in part, at a price of $.001 per right at any time prior to the acquisition by a person or group of affiliated or associated persons of beneficial ownership of 15% or more of the voting power of all of our outstanding capital stock, unless extended.

We cannot redeem shares of Series A Junior Participating Preferred Stock purchasable upon the exercise of the rights. Each share of Series A Junior Participating Preferred Stock will be entitled to a minimum preferential quarterly dividend payment of $1 per share but will be entitled to an aggregate dividend of 100 times the dividend declared per share of common stock whenever such dividend is declared. In the event of liquidation, the holders of Series A Junior Participating Preferred Stock will be entitled to a minimum preferential liquidation payment of $100 per share but will be entitled to an aggregate payment of 100 times the payment made per share of common stock. Each share of Series

A Junior Participating Preferred Stock will have 100 votes, voting together with the holders of the common stock. In the event of any merger, consolidation or other transaction in which shares of common stock are exchanged, each share of Series A Junior Participating Preferred Stock will be entitled to receive 100 times the amount received per share of common stock.

Our board of directors may adjust the purchase price of Series A Junior Participating Preferred Stock, the number of shares of Series A Junior Participating Preferred Stock issuable, and the number of our outstanding rights to prevent dilution that may occur from a stock dividend, a stock split or a reclassification of our Series A Junior Participating Preferred Stock. No adjustments to the purchase price of our Series A Junior Participating Preferred Stock of less than 1% will be made.

The purpose of the rights plan is to encourage potential acquirors to negotiate with our board of directors prior to attempting a takeover and to give the board leverage in negotiating on behalf of the stockholders the terms of any proposed takeover. The rights are intended to have anti-takeover effects. If the rights become exercisable, the rights will cause substantial dilution to a person or group that attempts to acquire or merge with us in most circumstances. Accordingly, the existence of the rights plan may deter a potential acquiror from making a takeover proposal or tender offer for an outstanding common stock. The rights should not interfere with any merger or other business combination approved by our board of directors as we may redeem the rights as described below and since a transaction approved by our board of directors would not cause the rights to become exercisable.

The terms of our rights agreement may be amended by our board of directors without the consent of the holders of our rights. After a person or group becomes an acquiring person, our board of directors may not amend the agreement in a way that adversely affects holders of our rights.

    Delaware Takeover Statute

We are subject to Section 203 of the Delaware General Corporation Law, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any ‘‘business combination’’ (as

24

Table of Contents

defined below) with any ‘‘interested stockholder’’ (as defined below) for a period of three years following the date that such stockholder became an interested stockholder, unless: (1) prior to such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; (2) on consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (x) by persons who are directors and also officers and (y) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or (3) on or subsequent to such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 of the Delaware General Corporation Law defines ‘‘business combination’’ to include: (1) any merger or consolidation involving the corporation and the interested stockholder; (2) any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder; (3) subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; (4) any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or (5) the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation. In general, Section 203 defines an ‘‘interested stockholder’’ as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person.

 DESCRIPTION OF WARRANTS WE MAY OFFER 

The following information outlines the material provisions of each warrant agreement, the warrants and the warrant certificates. This information is only a summary and is qualified entirely by reference to the relevant warrant agreement with respect to the warrants of any particular series. The specific terms of any series of warrants will be described in the relevant prospectus supplement. If so described in a prospectus supplement, the terms of that series of warrants may differ from the general description of terms presented below.

General

We may issue warrants for the purchase of our debt securities or common stock. Warrants may be issued independently or together with debt securities or common stock, and may be attached to or separate from those securities.

Each series of warrants will be evidenced by certificates issued under a separate warrant agreement to be entered into between us and a bank, as warrant agent, selected by us with respect to such series, having its principal office in the U.S. and having combined capital and surplus of at least $50,000,000.

The relevant prospectus supplement relating to a series of warrants will mention the name and address of the warrant agent. The relevant prospectus supplement will describe the terms of the warrant agreement and the series of warrants in respect of which this prospectus is being delivered, including:

	•	the title of such warrants;

	•	the offering price and aggregate number of warrants offered;

	•	the currency in which the price of such warrants will be payable;

	•	the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;

	•	the date which the warrants and the related securities will be separately transferable;

	•	in the case of warrants to purchase debt securities, the principal amount of debt securities that can be purchased upon exercise of one warrant, and the price and currency for purchasing those debt securities upon exercise and, in the case of warrants to purchase common stock, the number of shares of common stock that can be purchased upon the exercise of one warrant, and the price and currency for purchasing such shares upon exercise;

	•	the terms of any rights to redeem or call or accelerate the expiration of the warrants;

	•	the dates on which the right to exercise the warrants will commence and expire and, if the warrants are not continuously exercisable, any dates on which the warrants are not exercisable;

	•	certain federal income tax consequences of holding or exercising those warrants;

	•	whether the warrants or related securities will be listed on any securities exchange;

	•	the terms of the securities issuable upon exercise of those warrants;

	•	whether the warrants will be issued in global or certificated form; and

	•	any other specific terms, preferences or rights of, or limitations or restrictions on, of the warrants.

Warrant certificates may be exchanged for new warrant certificates of different denominations, may be presented for transfer registration, and may be exercised at the warrant agent’s corporate trust office or any other office indicated in the relevant prospectus supplement. If the warrants are not separately transferable from the securities with which they were issued, this exchange may take place only if the certificates representing such related securities are also exchanged. Prior to warrant

Table of Contents

exercise, warrantholders will not have any rights as holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase debt securities, the right to receive principal, premium, if any, or interest payments, on the debt securities purchasable upon such exercise or to enforce covenants in the applicable indenture or, in the case of warrants to purchase any common stock, the right to receive any dividends, or payments upon any liquidation, dissolution or winding up of the Company or to exercise any voting rights.

Where appropriate, the applicable prospectus supplement will describe the U.S. federal income tax considerations relevant to the warrants.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities specified in the relevant prospectus supplement at the exercise price mentioned in, or calculated as described in, the relevant prospectus supplement. Unless otherwise specified in the relevant prospectus supplement, warrants may be exercised at any time up to 5:00 p.m., New York time, on the expiration date mentioned in that prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Warrants may be exercised by delivery of the warrant certificate representing the warrants to be exercised, or in the case of global securities by delivery of an exercise notice for those warrants, together with certain information, and payment to the warrant agent in immediately available funds, as provided in the relevant prospectus supplement, of the required purchase amount. The information required to be delivered will be on the reverse side of the warrant certificate and in the relevant prospectus supplement. Upon receipt of such payment and the warrant certificate or exercise notice properly executed at the warrant agent’s corporate trust office or any other office indicated in the relevant prospectus supplement, we will, in the time period the relevant warrant agreement provides, issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining amount of warrants.

If mentioned in the relevant prospectus supplement, securities may be surrendered as all or part of the exercise price for warrants.

Antidilution Provisions

In the case of warrants to purchase shares of our common stock, the exercise price payable and the number of shares of our common stock to be purchased upon warrant exercise may be adjusted in certain events, including:

	•	the issuance of a stock dividend to holders of our common stock or a combination, subdivision or reclassification of common stock;

	•	the issuance of rights, warrants or options to all holders of common stock entitling them to purchase common stock for an aggregate consideration per share less than the current market price per common stock share;

	•	any distribution to our common stockholders of evidences of our indebtedness or of assets, excluding cash dividends or distributions referred to above; and

	•	any other events mentioned in the relevant prospectus supplement.

No adjustment in the number of shares purchasable upon warrant exercise will be required until cumulative adjustments require an adjustment of at least 1% of such number. No fractional shares will be issued upon warrant exercise, but we will pay the cash value of any fractional shares otherwise issuable.

Modification

We and the relevant warrant agent may amend any warrant agreement and the terms of the related warrants by executing a supplemental warrant agreement, without any such warrantholder’s consent, for the purpose of:

27

---

Table of Contents

	•	curing any ambiguity, any defective or inconsistent provision contained in the warrant agreement, or making any other corrections to the warrant agreement that are not inconsistent with the provisions of the warrant certificates and which do not adversely affect the warrant holders’ interests or rights in any material respect;

	•	evidencing the succession of another corporation to Ormat and their assumption of Ormat’s covenants contained in the warrant agreement and the warrants;

	•	appointing a successor depositary, if the warrants are issued in the form of global securities; evidencing a successor warrant agent’s acceptance of appointment with respect to the warrants;

	•	adding to our covenants for the warrantholders’ benefit or surrendering any right or power conferred upon us under the warrant agreement; or

	•	issuing warrants in definitive form, if such warrants are initially issued in the form of global securities.

We and the warrant agent may also amend any warrant agreement and the related warrants by a supplemental agreement with the consent of the holders of a majority of the unexercised warrants such amendment affects, for the purpose of adding, modifying or eliminating any of the warrant agreement’s provisions or of modifying the holders’ rights. However, no such amendment that

	•	changes the number or amount of securities purchasable upon warrant exercise so as to reduce the number of securities receivable upon this exercise;

	•	shortens the time period during which the warrants may be exercised;

	•	otherwise adversely affects the exercise rights of such warrantholders in any material respect; or

	•	reduces the number of unexercised warrants the consent of holders of which is required for amending the warrant agreement or the related warrants may be made without the consent of each holder affected by that amendment.

Consolidation, Merger and Sale of Assets

Each warrant agreement will provide that we are generally permitted to consolidate or merge with another company or firm. We are also permitted to sell or lease substantially all of our assets to another company or firm, or to buy or lease substantially all of the assets of another company or firm. However, we may not take any of these actions unless the following conditions, among others, are met:

	•	Where we merge out of existence or sell or lease substantially all our assets, the other company or firm must be a corporation, partnership or trust organized under the laws of a State of the United States or the District of Columbia or under United States federal law, and it must agree to be legally responsible for the warrants.

	•	The consolidation, merger, sale of assets or other transaction must not cause a default on the warrants, and we must not already be in default, unless the transaction would cure the default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured. A default for this purpose would also include any event that would be an event of default if the requirements for giving us notice of our default or our default having to exist for a specific period of time were disregarded.

Enforceability of Rights by Holders of Warrants

Each warrant agent will act solely as our agent under the relevant warrant agreement and will not assume any obligation or relationship of agency or trust for any warrantholder. A single bank or trust company (so long as it otherwise qualifies under the warrant agreement to act as warrant agent) may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or

28

---

Table of Contents

responsibility in case we default in performing our obligations under the relevant warrant agreement or warrant, including any duty or responsibility to initiate any legal proceedings or to make any demand upon us. Any warrantholder may, without the warrant agent’s consent or of any other warrantholder, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, that warrant.

Replacement of Warrant Certificates

We will replace any destroyed, lost, stolen or mutilated warrant certificate upon delivery to us and the relevant warrant agent of evidence satisfactory to them of the ownership of that warrant certificate and of the destruction, loss, theft or mutilation of that warrant certificate, and (in the case of mutilation) surrender of that warrant certificate to the relevant warrant agent, unless we or the warrant agent has received notice that the warrant certificate has been acquired by a bona fide purchaser. That warrantholder will also be required to provide indemnity satisfactory to the relevant warrant agent and us before a replacement warrant certificate will be issued.

Title

We, the warrant agents and any of their agents may treat the registered holder of any warrant certificate as the absolute owner of the warrants evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the warrants so requested, despite any notice to the contrary.

 DESCRIPTION OF UNITS WE MAY OFFER 

The following summarizes the material provisions of the units that we may issue from time to time and which are important to holders of units. The applicable prospectus supplement will state whether any of the generalized provisions summarized below do not apply to the units being offered and it will provide any additional provisions applicable to the units being offered, including their tax treatment. The following description is only a summary and is subject to, and qualified in its entirety by reference to the terms and provisions of the form of unit agreement to be filed as an exhibit to the registration statement which contains this prospectus.

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The applicable prospectus supplement may describe:

	•	the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

	•	any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units;

	•	whether the units will be issued in fully registered or global form; and

	•	any other terms of the unit agreements.

 PLAN OF DISTRIBUTION 

We may offer and sell the securities from time to time as follows:

	•	to or through underwriters or dealers;

	•	directly to other purchasers;

	•	through designated agents; or

	•	through a combination of any of these methods of sale.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Any underwriter or agent involved in the offer and sale of the securities will be named in the applicable prospectus supplement.

In some cases, we may also repurchase the securities and reoffer them to the public by one or more of the methods described above. This prospectus and the applicable prospectus supplement may be used in connection with any offering of securities through any of these methods or other methods described in the applicable prospectus supplement.

The securities, including securities issued or to be issued by us or securities borrowed from third parties in connection with arrangements under which we agree to issue securities to underwriters or their affiliates on a delayed or contingent basis, that we distribute by any of these methods may be sold to the public, in one or more transactions, at:

	•	a fixed price or prices, which may be changed;

	•	market prices prevailing at the time of sale;

	•	prices related to prevailing market prices; or

	•	negotiated prices.

This prospectus may be delivered by underwriters and dealers in connection with short sales undertaken to hedge exposures under commitments to acquire securities of us to be issued on a delayed or contingent basis.

We may solicit, or may authorize underwriters, dealers or agents to solicit, offers to purchase securities directly from the public from time to time, including pursuant to contracts that provide for payment and delivery on future dates. We may also designate agents from time to time to solicit offers to purchase securities from the public on our behalf. The prospectus supplement relating to any particular offering of securities will name any agents designated to solicit offers, and will include information about any commissions we may pay the agents and will describe the material terms of any such delayed delivery arrangements, in that offering. Agents may be deemed to be ‘‘underwriters’’ as that term is defined in the Securities Act.

In connection with the sale of securities, underwriters may receive compensation from us or from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents

30

---

Table of Contents

that participate in the distribution of the securities may be deemed to be underwriters, and any discounts or commissions they receive from us, and any profit on the resale of the securities they realize may be deemed to be underwriting discounts and commissions under the Securities Act. Any such underwriter, dealer or agent will be identified, and any such compensation received will be described, in the applicable prospectus supplement.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or a post-effective amendment.

Unless otherwise specified in the applicable prospectus supplement, each series of the securities will be a new issue with no established trading market, other than the common stock. Any shares of common stock sold pursuant to a prospectus supplement will be trading on the New York Stock Exchange, subject to official notice of issuance. We may elect to list any of the other securities on an exchange, but are not obligated to do so. It is possible that one or more underwriters may make a market in a series of the securities, but will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, no assurance can be given as to the liquidity of the trading market for the securities.

If dealers are utilized in the sale of the securities, we will sell the securities to the dealers as principals. The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the applicable prospectus supplement.

We may enter into agreements with underwriters, dealers and agents who participate in the distribution of the securities which may entitle these persons to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make. Any agreement in which we agree to indemnify underwriters, dealers and agents against civil liabilities will be described in the applicable prospectus supplement.
