USE OF PROCEEDS

Unless we otherwise specify in the applicable prospectus supplement, we expect to use the net proceeds we receive from the sale of the ordinary shares, preferred shares, warrants, debt securities, depositary shares, and units, or any combination of these securities, for general corporate purposes which may include capital expenditures, the repayment or refinancing of debt, investments in our subsidiaries, working capital, or the financing of possible acquisitions or business opportunities. Pending such uses, we anticipate that we will invest the net proceeds in interest-bearing securities.

We will not receive any proceeds from the sale of securities by the selling securityholder. The selling securityholder named in this prospectus will pay any underwriting fees, discounts and commissions, along with any fees and expenses of underwriter’s counsel and certain of the selling securityholder’s out-of-pocket expenses, incurred in connection with its sale of securities registered under this prospectus. We will bear all other costs, fees and expenses incurred by us, or by the selling securityholder, in effecting the registration, offer and sale of the securities covered by this prospectus.

RATIO OF EARNINGS TO FIXED CHARGES

For the three months ended March 31, 2009 and the year ended December 31, 2008, earnings were not sufficient to cover fixed charges by approximately $822,000 and $51.9 million, respectively. For the year ended December 31, 2007, we had earnings, as defined, of approximately $6.8 million and fixed charges of approximately $21,000. As of the date of this prospectus, we have not issued any preferred shares.

DESCRIPTION OF SHARE CAPITAL

The following description of our share capital, together with the additional information we may include in any prospectus supplements (which may differ from the terms summarized below), summarizes the material terms and provisions of our share capital that we may offer under this prospectus.

We are authorized to issue 1,000,000 preferred shares, par value $0.001 per share. As of the date of this prospectus, we have no preferred shares outstanding. Our board of directors has the authority, without shareholder approval, to issue preferred shares in one or more series and to fix the rights, preferences, privileges and restrictions thereof.

DESCRIPTION OF WARRANTS

This section outlines some of the provisions of the warrants we may issue and the warrant agreement pursuant to which they may be issued. This description may not contain all of the information that is important to you and is qualified in its entirety by reference to the warrant agreement with respect to the warrants. The specific terms of any warrants will be described in the applicable prospectus supplement. If so described in a particular supplement, the specific terms of any warrants may differ from the general description of terms presented below.

General Description of Warrants

We may issue warrants for the purchase of debt securities, ordinary shares, preferred shares, depositary shares or units. Warrants may be issued independently, or together with other securities, and may be attached to or separate from any offered securities. We will issue warrants under one or more warrant agreements between us and the warrant agent that we will name in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include the following:

Exercise of Warrants

Each warrant will entitle the holder of the warrant to purchase at the exercise price set forth in the applicable prospectus supplement the amount of debt or equity securities being offered. Holders may exercise warrants at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will be void. Holders may exercise warrants as set forth in the applicable prospectus supplement.

Table of Contents

Until a holder exercises the warrants to purchase any securities underlying the warrants, the holder will not have any rights as a holder of the underlying securities by virtue of ownership of warrants.

DESCRIPTION OF DEBT SECURITIES AND SUBSIDIARY GUARANTEES

This section outlines some of the provisions of the debt securities and any related subsidiary guarantees we may issue and the indenture and supplemental indentures pursuant to which they may be issued. This description may not contain all of the information that is important to you and is qualified in its entirety by reference to the form of indenture and the applicable supplemental indenture with respect to the debt securities of any particular series and any related subsidiary guarantees. The specific terms of any series of debt securities and any related subsidiary guarantees will be described in the applicable prospectus supplement. If so described in a particular supplement, the specific terms of any series of debt securities and any related subsidiary guarantees may differ from the general description of terms presented below.

The indenture does not limit the amount of debt securities that may be issued. We may issue secured or unsecured debt securities. Our debt securities and any related subsidiary guarantees will be issued under an indenture to be entered into between us and a trustee to be designated by us, a form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Our debt securities may be convertible into our ordinary shares or other of our securities.

When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a supplement to this prospectus. We will also indicate in the prospectus supplement whether the general terms and provisions described in this prospectus apply to a particular series of debt securities. To the extent the information contained in the prospectus supplement differs from this summary description, you should rely on the information in the prospectus supplement.

Unless otherwise specified in a supplement to this prospectus, the debt securities and any related subsidiary guarantees will be the direct, unsecured obligations of the issuers thereof and will rank equally with all of the issuers’ other unsecured and unsubordinated indebtedness. The holders of our debt securities will be structurally subordinated to holders of any indebtedness (including trade payables) of any of our subsidiaries, except to the extent our subsidiaries guarantee our obligations under that series of debt securities.

We currently conduct our operations through subsidiaries. As a result, cash we obtain from our subsidiaries is the principal source of funds necessary to meet our debt service obligations. The debt securities may be fully and unconditionally guaranteed on a secured or unsecured, senior or subordinated basis, jointly and severally, by some or all of our direct and indirect wholly-owned subsidiaries. The obligations of each subsidiary guarantor, if any, under its guarantee, if any, will be limited as necessary under applicable law to prevent that guarantee from constituting a fraudulent conveyance under applicable law. In the event that any series of debt securities and any related subsidiary guarantees will be subordinated to other indebtedness that we or our subsidiary guarantors have outstanding or may incur, the terms of the subordination will be set forth in the prospectus supplement relating to such debt securities and related subsidiary guarantees.

We have described select portions of the indenture below. This description may not contain all of the information that is important to you. The form of indenture has been included as an exhibit to the registration statement of which this prospectus is a part, and you should read the indenture for provisions that may be important to you.

The terms of each series of debt securities and any related subsidiary guarantees will be established by or pursuant to a resolution of our board of directors and set forth or determined in the manner provided in a resolution of our board of directors, in an officers’ certificate or by a supplemental indenture.

9

Table of Contents

We may issue an unlimited amount of debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium, or at a discount. When we offer a particular series of debt securities, we will identify the title of the debt securities, the trustee or trustees (to which we refer in this description collectively as the trustee), any subsidiary guarantors and the aggregate principal amount of the debt securities we are offering, and we will describe the following terms of the debt securities, if applicable:

10

Table of Contents

We will provide you with information on the material United States federal income tax considerations and other special considerations applicable to any series of debt securities in the applicable prospectus supplement.

The indenture does not limit our ability to issue convertible or subordinated debt securities. Any conversion or subordination provisions of a particular series of debt securities will be set forth in the resolution of our board of directors, the officers’ certificate or supplemental indenture related to that series of debt securities and will be described in the relevant prospectus supplement.

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture.

One or more series of debt securities may be sold at a discount to their stated principal amount or may bear no interest or interest at a rate which at the time of issuance is below market rates. One or more series of debt securities may be variable rate debt securities that may be exchanged for fixed rate debt securities.

Debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, commodity indices, stock exchange indices, financial indices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, commodity indices, stock exchange indices, financial indices, equity indices or other factors to which the amount payable on such date is linked and certain additional United States federal income tax considerations will be set forth in the applicable prospectus supplement.

11

Table of Contents

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general United States federal tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

When we determine to issue debt securities, we will instruct the trustee to authenticate for issuance such debt securities in a principal amount that we will provide in a resolution of our board of directors, in an officers’ certificate or by a supplemental indenture. Our instructions may authorize the trustee to authenticate and deliver such debt securities upon our oral instructions or the oral instructions of our authorized agent or agents.

Transfer and Exchange

We expect most debt securities to be issued in denominations of $1,000 and integral multiples thereof. Each debt security will be represented by either one or more global securities deposited with and registered in the name of a depositary to be designated by us in the applicable prospectus supplement, or a nominee (we refer to any debt security represented by a global security as a “book-entry debt security”), or by a certificate issued in definitive registered or bearer form (we refer to any fully registered debt security represented by a certificate as a “registered certificated debt security”), as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Securities” below, book-entry debt securities will not be issuable in certificated form.

You may transfer or exchange registered certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. No service charge will be made for any transfer or exchange of registered certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

You may effect the transfer of registered certificated debt securities, and the right to receive the principal of and interest on those registered certificated debt securities, only by surrendering the certificate representing those registered certificated debt securities and the issuance by us or the trustee of a certificate to the new holder.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary (the “depositary”) identified in the prospectus supplement. Global securities will be issued to the depositary in registered certificated form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

Governing Law

The indenture, the debt securities and any subsidiary guarantees shall be construed in accordance with and governed by the laws of the State of New York.

DESCRIPTION OF DEPOSITARY SHARES

General

We may elect to offer depositary shares, each representing a fraction (to be set forth in the prospectus supplement relating to a particular series of preferred shares) of a share of a particular series of preferred shares as described below. In the event we elect to do so, depositary receipts evidencing depositary shares will be issued to the public.

The shares of any class or series of preferred shares represented by depositary shares will be deposited under a deposit agreement among us, a depositary selected by us and the holders of the depositary receipts. The depositary will be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a preferred share represented by such depositary share, to all the rights and preferences of the preferred shares represented thereby (including dividend, voting, redemption and liquidation rights).

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of the related class or series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement. Copies of the forms of deposit agreement and depositary receipt will be filed as exhibits to or incorporated by reference in the registration statement of which this prospectus forms a part, and the following summary is qualified in its entirety by reference to such exhibits.

Pending the preparation of definitive depositary receipts, the depositary may, upon our written order, issue temporary depositary receipts substantially identical to (and entitling the holders thereof to all the rights pertaining to) the definitive depositary receipts but not in definitive form. Definitive depositary receipts will be prepared thereafter without unreasonable delay, and temporary depositary receipts will be exchangeable for definitive depositary receipts without charge to the holder thereof.

Dividends and Distributions

The depositary will distribute all cash dividends or other distributions received in respect of the related class or series of preferred shares to the record holders of depositary shares relating to such class or series of preferred shares in proportion to the number of such depositary shares owned by such holders.

In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary shares entitled thereto, unless the depositary determines that it is not feasible to make such distribution, in which case the depositary may, with our approval, sell such property and distribute the net proceeds from such sale to such holders.

Withdrawal of Shares

Upon surrender of the depositary receipts at the corporate trust office of the depositary (unless the related depositary shares have previously been called for redemption), the holder of the depositary shares evidenced thereby is entitled to delivery of the number of whole shares of the related class or series of preferred shares and any money or other property represented by such depositary shares. Holders of depositary shares will be entitled to receive whole shares of the related class or series of preferred shares on the basis set forth in the prospectus supplement for such class or series of preferred shares, but holders of such whole preferred shares will not thereafter be entitled to exchange them for depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole preferred shares to be withdrawn, the depositary will deliver to such holder at the same time a new

13

Table of Contents

depositary receipt evidencing such excess number of depositary shares. In no event will fractional preferred shares be delivered upon surrender of depositary receipts to the depositary.

Redemption of Depositary Shares

Whenever we redeem preferred shares held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing shares of the related class or series of preferred shares so redeemed. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to such class or series of preferred shares. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as may be determined by the depositary.

Voting the Preferred Shares

Upon receipt of notice of any meeting at which the holders of the preferred shares are entitled to vote, the depositary will mail the information contained in such notice of meeting to the record holders of the depositary shares relating to such preferred shares. Each record holder of such depositary shares on the record date (which will be the same date as the record date for the preferred shares) will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of the class or series of preferred shares represented by such holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of preferred shares represented by such depositary shares in accordance with such instructions, and we will agree to take all action which the depositary deems necessary in order to enable the depositary to do so. The depositary will abstain from voting preferred shares to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred shares.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between us and the depositary. However, any amendment which materially and adversely alters the rights of the holders of depositary receipts will not be effective unless such amendment has been approved by the holders of depositary receipts representing at least a majority (or, in the case of amendments relating to or affecting rights to receive dividends or distributions or voting or redemption rights, 66%, unless otherwise provided in the related prospectus supplement) of the depositary shares then outstanding. The deposit agreement may be terminated by us or the depositary only: (1) if all outstanding depositary shares have been redeemed; (2) if there has been a final distribution in respect of the related class or series of preferred shares in connection with our liquidation, dissolution or winding up and such distribution has been distributed to the holders of depositary receipts; or (3) upon the consent of holders of depositary receipts representing not less than 66% of the depositary shares outstanding.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the related class or series of preferred shares and any redemption of such preferred shares. Holders of depositary receipts will pay all other transfer and other taxes and governmental charges and such other charges as are expressly provided in the deposit agreement to be for their accounts.

The depositary may refuse to effect any transfer of a depositary receipt or any withdrawal of shares of a class or series of preferred stock evidenced thereby until all taxes and charges with respect to the depositary receipt or preferred shares are paid by the holders thereof.

The depositary will forward all reports and communications from us which are delivered to the depositary and which we are required to furnish to the holders of the preferred shares.

Neither the depositary will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the deposit agreement. Our obligations and the depositary under the deposit agreement will be limited to performance in good faith of their duties thereunder, and neither we nor the depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or class or series of preferred shares unless satisfactory indemnity is furnished. We and the depositary may rely on written advice of counsel or accountants, or information provided by persons presenting preferred shares for deposit, holders of depositary shares or other persons believed to be competent and on the documents believed to be genuine.

Resignation and Removal of the Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may at any time remove the depositary. Any such resignation or removal of the depositary will take effect upon the appointment of a successor depositary, which successor must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the U.S. and having a combined capital and surplus of at least $50,000,000.

DESCRIPTION OF UNITS

We may issue units comprised of one or more debt securities, our ordinary shares, our preferred shares, and warrants in any combination. 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 prospectus supplement will describe:

The provisions described in this section, as well as those described under “Description of Debt Securities and Subsidiary Guarantees,” “Description of Share Capital” and “Description of Warrants” will apply to each unit and to any debt security, preferred shares, ordinary shares, or warrant included in each unit, respectively.

Issuance in Series

We may issue units in such amounts and in as many distinct series as we wish. This section summarizes terms of the units that apply generally to all series. Most of the financial and other specific terms of a particular series will be described in the prospectus supplement.

Unit Agreements

We will issue the units under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. We may add, replace or terminate unit agents from time to time. We will identify the unit agreement under which each series of units will be issued and the unit agent under that agreement in the prospectus supplement.

Table of Contents

The following provision will generally apply to all unit agreements unless otherwise stated in the prospectus supplement.

Enforcement of Rights

The unit agent under a unit agreement will act solely as our agent in connection with the units issued under that agreement. The unit agent will not assume any obligation or relationship of agency or trust for or with any holders of those units or of the securities comprising those units. The unit agent will not be obligated to take any action on behalf of those holders to enforce or protect their rights under the units or the included securities.

Except as indicated in the next paragraph, a holder of a unit may, without the consent of the unit agent or any other holder, enforce its rights as holder under any security included in the unit, in accordance with the terms of that security and the indenture, warrant agreement or other instrument under which that security is issued. Those terms are described elsewhere in this prospectus under the sections relating to debt securities, preferred shares, ordinary shares and warrants.

Notwithstanding the foregoing, a unit agreement may limit or otherwise affect the ability of a holder of units issued under that agreement to enforce its rights, including any right to bring a legal action, with respect to those units or any securities, other than debt securities, that are included in those units. Limitations of this kind will be described in the prospectus supplement.

Modification Without Consent of Holders

We and the unit agent may amend any unit or unit agreement without the consent of any holder:

We do not need any approval to make changes that affect only units to be issued after the changes take effect. We may also make changes that do not adversely affect a particular unit in any material respect, even if they adversely affect other units in a material respect. In those cases, we do not need to obtain the approval of the holder of the unaffected unit; we need only obtain any required approvals from the holders of the affected units.

Modification With Consent of Holders

We may not amend any particular unit or a unit agreement with respect to any particular unit unless we obtain the consent of the holder of that unit, if the amendment would:

Any other change to a particular unit agreement and the units issued under that agreement would require the following approval:

16

Table of Contents

These provisions regarding changes with majority approval also apply to changes affecting any securities issued under a unit agreement, as the governing document. In each case, the required approval must be given by written consent.

Unit Agreements Will Not Be Qualified Under the Trust Indenture Act of 1939

No unit agreement will be qualified as an indenture, and no unit agent will be required to qualify as a trustee, under the Trust Indenture Act of 1939. Therefore, holders of units issued under unit agreements will not have the protections of the Trust Indenture Act of 1939 with respect to their units.

Title

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

SELLING SECURITYHOLDER

The (i) ordinary shares, (ii) warrants and (iii) ordinary shares that may be issued to the selling securityholder following the exercise of a warrant were issued to the selling securityholder in a private transaction in connection with Vantage’s acquisition of OGIL. OGIL was 100% owned by F3 Capital. F3 Capital, the selling securityholder, is 100% owned by Hsin-Chi Su, one of our directors. In connection with that transaction, we granted registration rights to the selling securityholder with respect to the resale or other disposal of the ordinary shares, warrants and ordinary shares that may be issued pursuant to the exercise of the warrant. At the time of issuance of these securities, F3 Capital had no agreements or understanding, directly or indirectly, to distribute these securities.

As a result of the significant level of ownership of our securities, the selling securityholder would be considered an “underwriter” within the meaning of the Securities Act with respect to the securities sold by it in this offering. The following tables set forth certain information with respect to the beneficial ownership of our ordinary shares and warrants by the selling securityholder as of May 15, 2009.

PLAN OF DISTRIBUTION

A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, subscriptions, exchangeable securities, forward delivery contracts and the writing of options.

In addition, the manner in which we, or the selling securityholder, may sell some or all of the securities covered by this prospectus includes, without limitation, through:

In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

In addition, we, or the selling securityholder, may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement or pricing supplement, as the case may be. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us

to close out any related short positions. We, or the selling securityholder, may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement or pricing supplement, as the case may be.

A prospectus supplement with respect to each series of securities will state the terms of the offering of the securities, including:

The offer and sale of the securities described in this prospectus by us, the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

General

Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be “underwriters” as defined in the Securities Act. Any discounts or commissions they receive from us and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We, or the selling securityholder, will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.

Underwriters and Agents

If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market price or at negotiated prices. We, or the selling securityholder, may offer the securities to the public through an underwriting syndicate or through a single underwriter. The underwriters in any particular offering will be mentioned in the applicable prospectus supplement or pricing supplement, as the case may be.

Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting

19

Table of Contents

agreement that we, or the selling securityholder, will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

We, or the selling securityholder, may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. We, or the selling securityholder, may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for us. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

In connection with offerings made through underwriters or agents, we, or the selling securityholder, may enter into agreements with such underwriters or agents pursuant to which we, or the selling securityholder, receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

Dealers

We, or the selling securityholder, may sell the offered securities to dealers as principals. We, or the selling securityholder, may negotiate and pay dealers’ commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale. Dealers engaged by us may allow other dealers to participate in resales.

Direct Sales

We may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved. In the event the selling securityholder sells its securities directly it would be considered an “underwriter” within the meaning of the Securities Act.

Institutional Purchasers

We, or the selling securityholder, may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or pricing supplement, as the case may be will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

We, or the selling securityholder, will enter into such delayed contracts only with institutional purchasers that we, or the selling securityholder, approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

Indemnification; Other Relationships

We, or the selling securityholder, may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents,

20

Table of Contents

underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.

Market-Making, Stabilization and Other Transactions

There is currently no market for any of the offered securities, other than our public units, public warrants and ordinary shares which are listed on the NYSE Amex. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We, or the selling securityholder, have no current plans for listing of the debt securities, preferred shares or warrants on any securities exchange or on the National Association of Securities Dealers, Inc. automated quotation system; any such listing with respect to any particular debt securities, preferred shares or warrants will be described in the applicable prospectus supplement or pricing supplement, as the case may be.

In connection with any offering of ordinary shares, the underwriters may purchase and sell ordinary shares in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of ordinary shares in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. “Covered” short sales are sales of shares made in an amount up to the number of shares represented by the underwriters’ over-allotment option. In determining the source of shares to close out the covered syndicate 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 the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the ordinary shares in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make “naked” short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing ordinary shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may 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. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.

In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Fees and Commissions

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc. (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement or pricing supplement, as the case may be.
