It does not contain the same level of disclosure as an initial public offering prospectus. In making representations in this Prospectus regard has been had to the fact that the Company is a disclosing entity for the purposes of the Corporations Act and certain matters may reasonably be expected to be known to investors and professional advisers whom potential investors may consult.

The key risk factors of which investors should be aware are set out in Section 4 of this Prospectus.

1.4 Shortfall Offer

Any Entitlement not taken up pursuant to the Offer will form the Shortfall Offer.

The Shortfall Offer is a separate offer made pursuant to this Prospectus and will remain open for up to three months following the Closing Date. The issue price for each Option to be issued under the Shortfall Offer shall be 0.5 cents being the price at which Options have been offered under the Offer.

The Directors reserve the right to issue Shortfall Options at their absolute discretion. Accordingly, do not apply for Shortfall Options unless instructed to do so by the Directors or Alto Capital.

1.5 Manager to the Offer

The Company has entered a mandate letter agreement with Alto Capital to act as manager to the Offer, including the placement of the Shortfall.

The fee payable to Alto Capital under the mandate is $10,000 (excluding GST) plus 5% (excluding GST) of the amount raised pursuant to the Shortfall Offer.

Mathew Walker, a Director, is a director of and has a relevant interest in 6% of the shares on issue in Alto Capital.

1.6 ASX listing

Application for Official Quotation of the Options offered pursuant to this Prospectus was made on 23 May 2011. If ASX does not grant Official Quotation of the Options offered pursuant to this Prospectus before the expiration of 3 months after the date of issue of the Prospectus, (or such period as varied by the ASIC), the Company will not issue any Options and will repay all application monies for the Options within the time prescribed under the Corporations Act, without interest.

The fact that ASX may grant Official Quotation to the Options is not to be taken in any way as an indication of the merits of the Company or the Options now offered for subscription.

1.7 Allotment

Options issued pursuant to the Offer will be allotted in accordance with the ASX Listing Rules and timetable set out at the commencement of this Prospectus.

Options issued pursuant to the Shortfall Offer will be allotted on a progressive basis. Where the number of Options issued is less than the number applied for, or where no allotment is made surplus application monies will be refunded without any interest to the Applicant as soon as practicable after the closing date of the Shortfall Offer.

Pending the allotment and issue of the Options or payment of refunds pursuant to this Prospectus, all application monies will be held by the Company in trust for the Applicants in a separate bank account as required by the Corporations Act. The Company, however, will be entitled to retain all interest that accrues on the bank account and each Applicant waives the right to claim interest.

Holding statements for Options issued under the Offer will be mailed in accordance with the ASX Listing Rules and timetable set out at the commencement of this Prospectus and for Shortfall Options issued under the Shortfall Offer as soon as practicable after their issue.

1.8 Overseas Shareholders

This Offer does not, and is not intended to, constitute an offer in any place or jurisdiction in which, or to any person to whom, it would not be lawful to make such an offer or to issue this Prospectus.

It is not practicable for the Company to comply with the securities laws of overseas jurisdictions having regard to the number of overseas Shareholders, the number and value of Options these Shareholders would be offered and the cost of complying with regulatory requirements in each relevant jurisdiction. Accordingly, the Offer is not being extended and Options will not be issued to Shareholders with a registered address which is outside Australia or New Zealand.

Shareholders resident in New Zealand should consider the additional statements set out in Section 1.9 of this Prospectus and should consult their professional advisors as to whether any government or other consents are required, or other formalities need to be observed, to enable them to exercise their Entitlements under the Offer.

1.9 Offer in New Zealand

The Offer to New Zealand investors is a regulated offer made under Australian and New Zealand law. In Australia, this is Chapter 8 of the Corporations Act and the Corporations Regulations 2001. In New Zealand, this is Part 5 of the Securities Act 1978 and the Securities (Mutual Recognition of Securities Offerings – Australia) Regulations 2008.

The Offer and the content of the Prospectus are principally governed by Australian rather than New Zealand law. In the main, the Corporations Act sets out how the Offer must be made.

There are differences in how securities are regulated under Australian law.

The rights, remedies, and compensation arrangements available to New Zealand investors in Australian securities may differ from the rights, remedies, and compensation arrangements for New Zealand securities.

Both the Australian and New Zealand securities regulators have enforcement responsibilities in relation to the Offer. If you need to make a complaint about the Offer, please contact the Financial Markets Authority, Wellington, New Zealand. The Australian and New Zealand regulators will work together to settle your complaint.

The taxation treatment of Australian securities is not the same as for New Zealand securities.

If you are uncertain about whether this investment is appropriate for you, you should seek the advice of an appropriately qualified financial adviser.

The Offer may involve a currency exchange risk. The currency for the securities is not New Zealand dollars. The value of the securities will go up or down according to changes in the exchange rate between that currency and New Zealand dollars. These changes may be significant. If you expect the securities to pay any amounts in a currency that is not New Zealand dollars, you may incur significant fees in having the funds credited to a bank account in New Zealand in New Zealand dollars.

As stated at Section 1.6 of this Prospectus, the Company will apply to ASX for quotation of the Options offered under this Prospectus. If quotation is granted the Options offered under this Prospectus will be able to be traded on ASX. If you wish to trade the securities through that market, you will have to make arrangements for a participant in that market to sell the securities on your behalf. If the securities market does not operate in New Zealand, the way in which the market operates, the regulation of participants in that market, and the information available to you about the securities and trading may differ from securities markets that operate in New Zealand.

1.10 Enquiries

Any questions concerning the Offer should be directed to James Robinson, Company Secretary, on +61 8 6460 4960.

2. PURPOSE AND EFFECT OF THE OFFER

2.1 Purpose of the Offer

The purpose of the Offer is to raise up to approximately $380,000 after estimated expenses of the Offer of $50,000 (refer to Section 5.7 of this Prospectus for further details relating to the estimated expenses of the Offer).

The funds raised from the Offer are planned to be used to fund part of the Company’s share of dry hole costs of a test well at the Lyons Point Prospect. However, as the funds to be raised from the Offer when combined with the Company’s existing cash reserves as at the date of this Prospectus are not sufficient to cover the Company’s share of the dry hole costs for the test well at the Lyons Point Prospect[1] the Company will also be undertaking a placement of Shares and Options to raise up to a further $1,190,000 (Placement) (refer to Section 2.4 of this Prospectus for further details).

In the event the Company does not raise funds sufficient to cover its share of dry hole costs of the test well (i.e. from the Offer and the Placement or any other source of funding), it will not proceed with the participation in the Lyons Point Prospect and will instead use the funds raised under the Offer for general working capital, including but not limited to, appraisal of other project opportunities and operating costs.

1 The estimated before casing point costs are US$1,339,790 of which US$127,308.45 has already been paid leaving a balance of US$1,212,481.55 (or approximately $1,131,000 using an exchange rate of 1.0721 ($:US$) as at 1 June 2011).

2.2 Effect of the Offer

The principal effect of the Offer, assuming all Options offered under the Prospectus are issued, will be to:

(a) increase the cash reserves by $380,000 (after deducting the estimated expenses of the Offer) immediately after completion of the Offer; and
(b) increase the number of Options on issue from nil as at the date of this Prospectus to 86,000,000 Options.

2.3 Pro-forma balance sheet

The audited consolidated balance sheet as at 31 March 2011 and the unaudited pro-forma balance sheet as at 31 March 2011 shown below have been prepared on the basis of the accounting policies normally adopted by the Company and reflect the changes to its financial position.

The pro-forma balance sheet has been prepared assuming firstly, all Options offered under the Prospectus are issued and secondly, all Options offered under the Prospectus and the Placement are issued.

The pro-forma balance sheet has been prepared to provide investors with information on the assets and liabilities of the Company and pro-forma assets and liabilities of the Company as noted below. The historical and pro-forma financial information is presented in an abbreviated form, insofar as it does not include all of the disclosures required by Australian Accounting Standards applicable to annual financial statements.

1 As announced on 23 May 2011, the Company will also be undertaking a placement of up to 34,000,000 Shares at an issue price of 3.5 cents per Share, together with 34,000,000 free attaching Options on the same terms as those issued under the Offer (on a 1:1 basis with each Share subscribed for and issued), to raise up to $1,190,000 (Placement). The Placement is subject to Shareholder approval which is intended to be sought at the annual general meeting of Shareholders to be held on or about 8 July 2011 as such the Shares and Options the subject of the Placement will not be issued prior to the completion of the Offer.

2.5 Effect on substantial Shareholders

The Offer will have no effect on the quantity of Shares held by these substantial holders as only Options are being issued.

3. RIGHTS AND LIABILITIES ATTACHING TO SECURITIES

3.1 Options

The Options to be issued pursuant to this Prospectus entitle the holder to subscribe for Shares on the following terms and conditions:

(a) Subject to paragraph (k), each Option gives the Optionholder the right to subscribe for one Share.
(b) The Options will expire at 5.00pm (WST) on 30 June 2012 (Expiry Date). Any Option not exercised before the Expiry Date will automatically lapse on the Expiry Date.
(c) The amount payable upon exercise of each Option will be $0.06 (Exercise Price).
(d) The Options held by each Optionholder may be exercised in whole or in part, and if exercised in part, multiples of 1,000 must be exercised on each occasion.
(e) An Optionholder may exercise their Options by lodging with the Company, before the Expiry Date:
(i) a written notice of exercise of Options specifying the number of Options being exercised; and
(ii) a cheque or electronic funds transfer for the Exercise Price for the number of Options being exercised;

(Exercise Notice).

(f) An Exercise Notice is only effective when the Company has received the full amount of the Exercise Price in cleared funds.
(g) Within 10 Business Days of receipt of the Exercise Notice accompanied by the Exercise Price, the Company will allot the number of Shares required under these terms and conditions in respect of the number of Options specified in the Exercise Notice.
(h) The Company will apply for quotation of the Options on ASX and all Options are freely transferable.
(i) All Shares allotted upon the exercise of Options will upon allotment rank pari passu in all respects with other Shares.
(j) The Company will apply for quotation of all Shares allotted pursuant to the exercise of Options on ASX within 10 Business Days after the date of allotment of those Shares.
(k) If at any time the issued capital of the Company is reconstructed, all rights of an Optionholder are to be changed in a manner consistent with the Corporations Act and the ASX Listing Rules at the time of the reconstruction.
(l) There are no participating rights or entitlements inherent in the Options and Optionholders will not be entitled to participate in new issues of capital offered to Shareholders during the currency of the Options.

However, the Company will ensure that for the purposes of determining entitlements to any such issue, the record date will be at least 7 Business Days after the issue is announced. This will give Optionholders the opportunity to exercise their Options prior to the date for determining entitlements to participate in any such issue.

(m) Subject to paragraph (k), an Option does not confer the right to a change in exercise price or a change in the number of underlying securities over which the Option can be exercised.

3.2 Shares

The following is a summary of the more significant rights and liabilities attaching to Shares being the underlying securities of the Options to be issued pursuant to this Prospectus. This summary is not exhaustive and does not constitute a definitive statement of the rights and liabilities of Shareholders. To obtain such a statement, persons should seek independent legal advice.

Full details of the rights and liabilities attaching to Shares are set out in the Constitution, a copy of which is available for inspection at the Company’s registered office during normal business hours.

(a) General meetings

Shareholders are entitled to be present in person, or by proxy, attorney or representative to attend and vote at general meetings of the Company.

Shareholders may requisition meetings in accordance with Section 249D of the Corporations Act and the Constitution of the Company.

(b) Voting rights

Subject to any rights or restrictions for the time being attached to any class or classes of shares, at general meetings of shareholders or classes of shareholders:

(i) each Shareholder entitled to vote may vote in person or by proxy, attorney or representative;
(ii) on a show of hands, every person present who is a Shareholder or a proxy, attorney or representative of a Shareholder has one vote; and
(iii) on a poll, every person present who is a Shareholder or a proxy, attorney or representative of a Shareholder shall, in respect of each Share held by him, or in respect of which he is appointed a proxy, attorney or representative, have one vote for each Share held, but in respect of partly paid shares shall have a fraction of a vote equivalent to the proportion which the amount paid up bears to the total issue price for the share.

(c) Dividend rights

The Directors may from time to time declare a dividend to be paid to the Shareholders entitled to the dividend. Subject to the rights of any preference Shareholders and to the rights of the holders of any shares credited or raised under any special arrangement as to dividend, the

dividend as declared shall be payable on all Shares according to the proportion that the amount paid (not credited) is of the total amounts paid and payable (excluding amounts credited) in respect of such Shares in accordance with Part 2H.5 of Chapter 2H of the Corporations Act. The Directors may from time to time pay to the Shareholders any interim dividends as they may determine. No dividends shall be payable except out of profits. A determination by the Directors as to the profits of the Company shall be conclusive. No dividend shall carry interest as against the Company.

The Directors may set aside out of the profits of the Company any amounts that they may determine as reserves, to be applied at the discretion of the Directors, for any purpose for which the profits of the Company may be properly applied.

The Directors may from time to time grant to Shareholders or any class of shareholders the right to elect to reinvest cash dividends paid by the Company by subscribing for Shares in the Company on such terms and conditions as the Directors think fit. The Directors may, at their discretion, resolve in respect of any dividend which it is proposed to pay or to declare on any Shares of the Company, that holders of such Shares may elect to forgo their right to the whole or part of the proposed dividend and to receive instead an issue of Shares credited as fully paid to the extent and on the terms and conditions of the Constitution.

(d) Winding-up

If the Company is wound up, the liquidator may, with the authority of a special resolution, divide among the Shareholders in kind the whole or any part of the property of the Company, and may for that purpose set such value as he considers fair upon any property to be so divided, and may determine how the division is to be carried out as between the Shareholders or different classes of Shareholders.

The liquidator may, with the authority of a special resolution, vest the whole or any part of any such property in trustees upon such trusts for the benefit of the contributories as the liquidator thinks fit, but so that no Shareholder is compelled to accept any shares or other securities in respect of which there is any liability.

(e) Shareholder liability

As the Shares issued on exercise of the Options will be fully paid shares, they will not be subject to any calls for money by the Directors and will therefore not become liable for forfeiture.

(f) Transfer of Shares

Generally, shares in the Company are freely transferable, subject to formal requirements, the registration of the transfer not resulting in a contravention of or failure to observe the provisions of a law of Australia and the transfer not being in breach of the Corporations Act and the ASX Listing Rules.

(g) Variation of rights

Under Section 246B of the Corporations Act, the Company may, with the sanction of a special resolution passed at a meeting of Shareholders

vary or abrogate the rights attaching to shares.

If at any time the share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the terms of issue of the shares of that class), whether or not the Company is being wound up, may be varied or abrogated with the consent in writing of the holders of three quarters of the issued shares of that class, or if authorised by a special resolution passed at a separate meeting of the holders of the shares of that class.

(h) Alteration of Constitution

In accordance with the Corporations Act, the Constitution can only be amended by a special resolution passed by at least three quarters of Shareholders present and voting at the general meeting. In addition, at least 28 days written notice specifying the intention to propose the resolution as a special resolution must be given.

4. RISK FACTORS

4.1 Introduction

The Options offered under this Prospectus are considered highly speculative. An investment in the Company is not risk free and the Directors strongly recommend potential investors to consider the risk factors described below, together with information contained elsewhere in this Prospectus and to consult their professional advisers before deciding whether to apply for Options pursuant to this Prospectus.

There are specific risks which relate directly to the Company’s business. In addition, there are other general risks, many of which are largely beyond the control of the Company and the Directors. The risks identified in this section, or other risk factors, may have a material impact on the financial performance of the Company and the market price of the Options.

The following is not intended to be an exhaustive list of the risk factors to which the Company is exposed.

4.2 Company specific

(a) Requirement for additional capital

The funds raised from the Offer combined with the Company’s existing cash reserves as at the date of this Prospectus are not sufficient to cover the Company’s share of the dry hole costs for the test well at the Lyons Point Prospect. The Company will be undertaking a placement to raise up to a further $1,190,000 (Placement) as further described in Section 2.4 of this Prospectus to be used primarily for the remaining dry hole costs of the test well not funded by the funds raised from the Offer or the Company’s existing cash reserves.

In addition, following the conclusion of drilling of the test well the Company may elect to participate in any completion attempt at the casing point of the test well at the Lyons Point Prospect. In the event this election is made the Company will incur additional costs in proportion to its then working interest of 17.25%. The Company’s share of these completion costs is estimated to be US$518,362.50 (approximately $483,500 using an exchange rate of 1.0721 ($:US$) as at 1 June 2011). The Board has not yet made this election and will consider the results of the drilling of the test well before making any further decision. If the Company does elect to participate in any completion attempt at the casing point of the test well, the Company will need to raise additional funds to pay for these additional costs.

Any additional equity financing will dilute shareholdings, and debt financing, if available, may involve restrictions on financing and operating activities. There is no guarantee that the Placement will be completed or the Company will be able to secure any other additional funding or be able to secure funding on terms favourable to the Company. If the Company is unable to contribute to its share of additional costs it will forfeit its interest in the Lyons Point Prospect.

(b) Contractual

The Company is party to various contracts, including the participation agreement associated with the Lyons Point Prospect and, if successful

and the Company elects to complete the test well and participate in subsequent wells, a joint operation agreement associated with the Lyons Point Prospect. The ability of the Company to achieve its objectives will depend on the performance by the other parties to those contracts (e.g. the operator of the Lyons Point Prospect). If a party defaults in the performance of its obligations it may be necessary for the Company to approach a court to seek a legal remedy. Legal action can be costly and there can be no guarantee that a legal remedy will be ultimately granted on the appropriate terms.

4.3 Industry specific

(a) Exploration

The prospects in which the Company has an interest are at various stages of exploration, and potential investors should understand that exploration and development are high-risk undertakings.

There can be no assurance that exploration of these prospects, or any other prospects that may be acquired in the future, will result in the discovery of a commercial oil and gas reserve. Even if an apparently viable reserve is identified, there is no guarantee that it can be economically exploited or will flow at commercial rates.

The exploration costs of the Company are based on certain assumptions with respect to the method and timing of exploration. By their nature, these estimates and assumptions are subject to significant uncertainties and, accordingly, the actual costs may materially differ from these estimates and assumptions. Accordingly, no assurance can be given that the cost estimates and the underlying assumptions will be realised in practice, which may materially and adversely affect the Company’s viability.

(b) Operating

The operations of the Company may be affected by various factors, including failure to locate or identify oil and gas reserves, failure to achieve predicted well production flow rates, operational and technical difficulties encountered in production, difficulties in commissioning and operating plant and equipment, mechanical failure or plant breakdown, unanticipated reservoir problems which may affect field production performance, adverse weather conditions, industrial and environmental accidents, industrial disputes and unexpected shortages or increases in the costs of consumables, spare parts, plant and equipment.

No assurances can be given that the Company will achieve commercial viability through the successful exploration and/or production of its prospect interests.

(c) Oil and gas reserves and commercial flow

Oil and gas reserves are expressions of judgment based on knowledge, experience and industry practice. Estimates, which were valid when originally calculated, may change significantly when new information or techniques becomes available. In addition, by their nature, oil and gas reserves are imprecise and depend to some extent on interpretations which may prove to be inaccurate. As further information becomes

available through additional fieldwork and analysis, the estimates are likely to change. This may result in alterations to development and commercial flow plans which may, in turn, either benefit or adversely affect the Company’s operations.

(d) Oil and gas price volatility and exchange rate

If the Company achieves success leading to oil and gas production, the revenue it will derive through the sale of oil and gas exposes the potential income of the Company to oil and gas price and exchange rate risks. Oil and gas prices fluctuate and are affected by many factors beyond the control of the Company. Such factors include supply and demand fluctuations, technological advancements, forward selling activities and other macro-economic factors.

Furthermore, international prices of oil and gas are denominated in United States dollars, whereas the income and expenditure of the Company are and will be taken into account in Australian currency, exposing the Company to the fluctuations and volatility of the rate of exchange between the United States dollar and the Australian dollar as determined in international markets.

(e) Environmental

The operations and proposed activities of the Company are subject to laws and regulations concerning the environment applicable in the jurisdiction of those activities. As with most production operations, the Company’s activities are expected to have an impact on the environment, particularly if advanced exploration or production proceeds. It is the Company’s practice to conduct its activities to the highest standard of environmental obligation, including compliance with all environmental laws. Nevertheless, there are certain risks inherent in the Company’s activities such as accidental leakages or spills, or other unforeseen circumstances which could subject the Company to extensive liability.

(f) Sovereign

The Company's projects outside Australia are subject to the risks associated in operating in a foreign country. These risks may include economic, social or political instability or change, hyperinflation, currency non-convertibility or instability and changes of law affecting foreign ownership, government participation, taxation, working conditions, rates of exchange, exchange control, exploration licensing, export duties, repatriation of income or return of capital, environmental protection, labour relations as well as government control over natural resources or government regulations that require the employment of local staff or contractors or require other benefits to be provided to local residents. Any future material adverse changes in government policies or legislation in foreign jurisdictions in which the Company has projects that affect foreign ownership, exploration, development or activities of companies involved in oil and gas exploration and production, may affect the viability and profitability of the Company.

4.4 General risks

(a) Economic

General economic conditions, movements in interest and inflation rates and currency exchange rates may have an adverse effect on the Company’s exploration, development and production activities, as well as on its ability to fund those activities.

(b) Market conditions

Share market conditions may affect the value of the Company’s quoted securities regardless of the Company’s operating performance. Share market conditions are affected by many factors such as:

general economic outlook;
interest rates and inflation rates;
changes in investor sentiment toward particular market sectors;
the demand for, and supply of, capital; and
terrorism or other hostilities.

The market price of securities can fall as well as rise and may be subject to varied and unpredictable influences on the market for equities in general and resource exploration stocks in particular. Neither the Company nor the Directors warrant the future performance of the Company or any return on an investment in the Company.

(c) Dividends

Any future determination as to the payment of dividends by the Company will be at the discretion of the Directors and will depend on the financial condition of the Company, future capital requirements and general business and other factors considered relevant by the Directors. No assurance in relation to the payment of dividends or franking credits attaching to dividends can be given by the Company.

(d) Taxation

The acquisition and disposal of Shares and Options will have tax consequences, which will differ depending on the individual financial affairs of each investor. All potential investors in the Company are urged to obtain independent financial advice about the consequences of acquiring Shares and Options from a taxation viewpoint and generally.

To the maximum extent permitted by law, the Company, its officers and each of their respective advisors accept no liability and responsibility with respect to the taxation consequences of subscribing for Options under this Prospectus.

(e) Reliance on key personnel

The responsibility of overseeing the day-to-day operations and the strategic management of the Company depends substantially on its

senior management and its key personnel. There can be no assurance given that there will be no detrimental impact on the Company if one or more of these employees cease their employment.

4.5 Speculative investment

The above list of risk factors ought not to be taken as exhaustive of the risks faced by the Company or by investors in the Company. The above factors, and others not specifically referred to above, may in the future materially affect the financial performance of the Company and the value of the Options offered under this Prospectus

Therefore, the Options to be issued pursuant to this Prospectus carry no guarantee with respect to the payment of dividends, returns of capital or the market value of those Options.

Potential investors should consider that the investment in the Company is speculative and should consult their professional advisers before deciding whether to apply for Options pursuant to this Prospectus.

5. ADDITIONAL INFORMATION

5.1 Litigation

As at the date of this Prospectus, the Company is not involved in any legal proceedings and the Directors are not aware of any legal proceedings pending or threatened against the Company.

5.2 Continuous disclosure obligations

The Company is a “disclosing entity” (as defined in Section 111AC of the Corporations Act) for the purposes of Section 713 of the Corporations Act and, as such, is subject to regular reporting and disclosure obligations. Specifically, like all listed companies, the Company is required to continuously disclose any information it has to the market which a reasonable person would expect to have a material effect on the price or the value of the Company’s securities.

This Prospectus is a “transaction specific prospectus”. In general terms a “transaction specific prospectus” is only required to contain information in relation to the effect of the issue of securities on a company and the rights attaching to the securities. It is not necessary to include general information in relation to all of the assets and liabilities, financial position, profits and losses or prospects of the issuing company.

This Prospectus is intended to be read in conjunction with the publicly available information in relation to the Company which has been notified to ASX and does not include all of the information that would be included in a prospectus for an initial public offering of securities in an entity that is not already listed on a stock exchange. Investors should therefore have regard to the other publicly available information in relation to the Company before making a decision whether or not to invest.

Having taken such precautions and having made such enquires as are reasonable, the Company believes that it has complied with the general and specific requirements of ASX as applicable from time to time throughout the 3 months before the issue of this Prospectus which required the Company to notify ASX of information about specified events or matters as they arise for the purpose of ASX making that information available to the stock market conducted by ASX.

Information that is already in the public domain has not been reported in this Prospectus other than that which is considered necessary to make this Prospectus complete.

The Company, as a disclosing entity under the Corporations Act states that:

(a) it is subject to regular reporting and disclosure obligations;
(b) copies of documents lodged with the ASIC in relation to the Company (not being documents referred to in Section 1274(2)(a) of the Corporations Act) may be obtained from, or inspected at, the offices of the ASIC; and
(c) it will provide a copy of each of the following documents, free of charge, to any person on request between the date of issue of this Prospectus and the Closing Date:

(i) the annual financial report most recently lodged by the Company with the ASIC;
(ii) any half-year financial report lodged by the Company with the ASIC after the lodgement of the annual financial report referred to in (i) and before the lodgement of this Prospectus with the ASIC; and
(iii) any continuous disclosure documents given by the Company to ASX in accordance with the ASX Listing Rules as referred to in Section 674(1) of the Corporations Act after the lodgement of the annual financial report referred to in (i) and before the lodgement of this Prospectus with the ASIC.

Copies of all documents lodged with the ASIC in relation to the Company can be inspected at the registered office of the Company during normal office hours.

Details of documents lodged by the Company with ASX since the date of lodgement of the Company’s latest annual financial report and before the lodgement of this Prospectus with the ASIC are set out in the table below.

Remuneration

The remuneration of an executive Director is decided by the Board, without the affected executive Director participating in that decision-making process. The total maximum remuneration of non-executive Directors is initially set by the Constitution and subsequent variation is by ordinary resolution of Shareholders in general meeting in accordance with the Constitution, the Corporations Act and the ASX Listing Rules, as applicable. The determination of non-executive Directors’ remuneration within that maximum will be made by the Board having regard to the inputs and value to the Company of the respective contributions by each non-executive Director. The current amount has been set at an amount not to exceed $250,000 per annum.

A Director may be paid fees or other amounts (i.e. non-cash performance incentives such as Options, subject to any necessary Shareholder approval) as the other Directors determine where a Director performs special duties or otherwise performs services outside the scope of the ordinary duties of a Director. In addition, Directors are also entitled to be paid reasonable travelling, hotel and other expenses incurred by them respectively in or about the performance of their duties as Directors.

For the financial years ended 31 March 2010 and 31 March 2011 the Company paid (or has payable) by way of approved remuneration for services provided by all Directors or former directors of the Company (executive, non-executive and alternate), companies associated with those Directors or former directors of

the Company or their associates in their capacity as Directors or former directors of the Company, employees, consultants or advisers (inclusive of employer superannuation contributions) a total of $130,184 and $311,487 respectively.

The proposed annual remuneration of the Directors for the financial year ending 31 March 2012 is set out in the table below.

5.7 Expenses of the Offer

In the event that the full amount of $430,000 is raised under this Prospectus, the total expenses of the Offer are estimated to be approximately $50,000 (excluding GST) and are expected to be applied towards the items set out in the table below:

ASIC fees ASX fees Legal fees Manager to the Offer fees* Printing and distribution Miscellaneous Total	$ 2,068 12,217 10,000 10,000 12,500 3,215
	50,000

Alto Capital will also receive a commission of 5% (excluding GST) of that amount raised pursuant to the Shortfall Offer. The maximum commission payable, assuming a 100% Shortfall and all those Shortfall Options are issued by the Company, is $21,500, which will increase the expenses of the Offer and result in an equivalent decrease in funds allocated to the dry hole costs of a test well at the Lyons Point Prospect as referred to Section 2.1 of this Prospectus. For each Entitlement accepted by Shareholders no commission will be payable.

5.8 Electronic Prospectus

Pursuant to Class Order 00/44, the ASIC has exempted compliance with certain provisions of the Corporations Act to allow distribution of an electronic prospectus and electronic application form on the basis of a paper prospectus lodged with the ASIC, and the publication of notices referring to an electronic

prospectus or electronic application form, subject to compliance with certain conditions.

If you have received this Prospectus as an electronic Prospectus, please ensure that you have received the entire Prospectus accompanied by the Application Forms. If you have not, please phone the Company on +61 8 6460 4960 and the Company will send you, for free, either a hard copy or a further electronic copy of the Prospectus, or both. Alternatively, you may obtain a copy of this Prospectus from the Company’s website athttp://www.tangopetroleum.com.au/ http://tangopetroleum.com.au/.

The Company reserves the right not to accept an Application Form from a person if it has reason to believe that when that person was given access to the electronic Application Form, it was not provided together with the electronic Prospectus and any relevant supplementary or replacement prospectus or any of those documents were incomplete or altered.

5.9 Clearing House Electronic Sub-Register System (CHESS) and Issuer Sponsorship

The Company will not be issuing option certificates. The Company is a participant in CHESS, for those investors who have, or wish to have, a sponsoring stockbroker. Investors who do not wish to participate through CHESS will be issuer sponsored by the Company. Because the sub-registers are electronic, ownership of securities can be transferred without having to rely upon paper documentation.

Electronic registers mean that the Company will not be issuing certificates to investors. Instead, investors will be provided with a statement (similar to a bank account statement) that sets out the number of Options allotted to them under this Prospectus. The notice will also advise holders of their Holder Identification Number or Security Holder Reference Number and explain, for future reference, the sale and purchase procedures under CHESS and issuer sponsorship.

Further monthly statements will be provided to holders if there have been any changes in their security holding in the Company during the preceding month.

5.10 Privacy Act

If you complete an application for Options, you will be providing personal information to the Company (directly or by the Company’s share registry). The Company collects, holds and will use that information to assess your application, service your needs as a holder of equity securities in the Company, facilitate distribution payments and corporate communications to you as a Shareholder and carry out administration.

The information may also be used from time to time and disclosed to persons inspecting the register, bidders for your securities in the context of takeovers, regulatory bodies, including the Australian Taxation Office, authorised securities brokers, print service providers, mail houses and the Company’s share registry.

You can access, correct and update the personal information that we hold about you. Please contact the Company or its share registry if you wish to do so at the relevant contact numbers set out in this Prospectus.

Collection, maintenance and disclosure of certain personal information is governed by legislation including the Privacy Act 1988 (Cth) (as amended), the Corporations Act and certain rules such as the ASX Settlement Operating Rules. You should note that if you do not provide the information required on the

application for Options, the Company may not be able to accept or process your application.
