Under Canadian GAAP, InterOil’s share in the LNG Joint venture project is proportionately consolidated and InterOil’s share of the JV cash flows will be taken up in InterOil consolidated cash flow statement. The cash flows would be classified between operating, investing and financing as per the nature of the transaction. Under U.S. GAAP, when an investment in an entity is accounted for by use of the equity method, an investor restricts its reporting in the cash flow statement to the cash flows between itself and the investee, for example, to dividends and advances. The above cash and cash equivalents is different to the Canadian cash and cash equivalents balance due to the proportionate take up of the cash balance under Canadian GAAP, but equity accounting of the LNG investment in U.S. GAAP (refer (8) below).

Per share amounts

Basic per share amounts are computed by dividing net income available to shareholders by the weighted average number of shares outstanding for the reporting period. Diluted per share amounts reflects the potential dilution that could occur if options or contracts to issue shares were exercised or converted into shares. The method of calculating diluted per share amounts under US GAAP is similar to the Canadian GAAP for the periods noted below.

For the calculation of diluted per share amounts, the basic weighted average number of shares is increased by the dilutive effect of stock options determined using the treasury method. Preferred stock, warrants, conversion options and stock options totaling 8,772,029 common shares at prices ranging from $13.67 to $43.22 were outstanding as at June 30, 2008 and were included in the computation of the diluted earnings per share at 30 June 2008. However, the dilutive instruments outstanding at June 30, 2007 were not included in the computation of the diluted loss per share because they caused the loss per share to be anti-dilutive.

(1)	Operations
	The Company determined that refinery operations commenced under U.S. GAAP at December 1, 2004, which is the date management assessed that construction of the refinery was substantially complete and ready for its intended use. The Company ceased capitalization of certain costs to the refinery project at this date and recognized one month’s results from sales, related costs of sales and operating expenses and administrative and general expenses in the statement of operations for the year ended December 31, 2004. As disclosed in note 3(q) in the consolidated financial statements, operations commenced on January 1, 2005 under Canadian GAAP. Therefore, the Company continued to capitalize December 2004’s results to the refinery project. Due to the difference in the cost basis of the refinery, the depreciation expense recorded under U.S. GAAP differs from that recorded under Canadian GAAP. The useful life for the refinery under U.S. GAAP is the same as that disclosed under Canadian GAAP.
(2)	Indirect participation interest
	As disclosed in note 18 in the unaudited consolidated financial statements, the Company entered into an indirect participation interest agreement in exchange for proceeds of $125,000,000. Under Canadian GAAP, this amount was apportioned between non financial liabilities and equity. Under U.S. GAAP, the Company has not bifurcated the amount as the Company has opted to utilize the scope exception under SFAS 133 Para 10(f) for ‘derivatives that serve as impediments to sales accounting’.
	As explained in note 18, on May 5, 2008, one of the investors who has a 4.1% interest in the eight well drilling program waived its right to convert its IPI percentage into 546,667 common shares. This waiver has resulted in conveyance being triggered on this portion of the IPI agreement for the quarter ended June 30, 2008. As the initial IPI proceeds were not bifurcated under U.S. GAAP, the total conveyance proceeds

Reconciliation to accounting principles generally accepted in the United States (cont’d)

	available for the conveyed interest is $9,448,458 (higher by $1,239,919 from the CGAAP balance), the amounts offset against oil and gas properties is $4,876,313 (higher by $413,306 from CGAAP balance), and the gain recognised in the statement of operations is $4,572,146 (higher by $826,613 from CGAAP balance).
(3)	Preference shares
	As disclosed in Note 21 in the unaudited consolidated financial statements, 517,777 preference shares were issued to an investor in November 2007 for $15,000,000.
	Under Canadian GAAP, the preference shares were assessed based on the rights attached to those shares and Management valued the equity and liability component of the instrument using the residual value basis.
	As the Preference share agreement has contractual redemption provisions under ‘Fundamental change’ section mainly relating to listing requirements, shareholding etc, under U.S. GAAP, the preference shares needs to be classified under temporary equity classification in accordance with ASR 268.
	In addition to the above, the 5% dividend paid for the six month period amounting to $372,950 has been included within long term borrowing costs within Canadian GAAP, but has been treated as a reduction to retained earnings under U.S. GAAP.
(4)	8% subordinated debentures
	As disclosed in Note 22 in the unaudited consolidated financial statements, on May 13, 2008, the Company completed the issue of $95,000,000 unsecured 8% subordinated convertible debentures with a maturity of five years. Under Canadian GAAP, these debentures were assessed based on the rights attached to the instrument and Management valued the equity and liability component of the instrument using the residual value basis.
	Under U.S. GAAP, Management assessed the debentures following the guidance under FAS 133 to decide whether the embedded conversion option needs to be bifurcated and disclosed separately. The embedded conversion option did not satisfy the condition of embedded derivatives that requires separation due to the scope exception under FAS 133 Para 11(a) as the option is indexed to the Company’s own stock and would have been classified in Shareholder’s equity if it had been separated.
	As FAS 133 bifurcation is not applicable, the provisions of EITF 00-27 requires that the instrument be assessed for any ‘Beneficial Conversion Features (‘BCF’)’ included in the instrument, which should be separated using the intrinsic value method as noted in EITF 98-5. Based on the guidance, the BCF has been valued at $8,821,320 which will be separate and classified separately under equity as Contributed Surplus. After separation, the liability component would be accreted over the life of the debentures, being 5 years till May 2013. If the conversion occurs prior to the stated redemption date, the entire unamortized value related to the converted portion would be immediately recognized in the Statement of operations as an ordinary interest expense.
	The accretion expense of the liability component for the period ending June 30, 2008 was $372,342 (accretion expense under US GAAP is less due to the higher liability component of the instrument).
	In addition to the above, deferred financial costs are offset against the respective liabilities under Canadian GAAP; however, the same is disclosed as a separate item on the face of the balance sheet under US GAAP. As at June 30, 2008, there was $193,998 of deferred finance costs which were not amortized in relation to the 8% convertible debentures.
(5)	Investment in LNG Project/Deferred gain on contributions to LNG Project
	As disclosed in Note 13 in the unaudited consolidated financial statements, a Shareholders Agreement was signed on July 30, 2007 which converted PNG LNG Inc. and its subsidiaries into a joint venture project from being a subsidiary of InterOil. Under Canadian GAAP, joint ventures are proportionately consolidated into the Company’s consolidated financials based on the shareholding in the joint venture.
	Applying the guidance under APB 18, a corporate joint venture has to be equity accounted under U.S. GAAP. InterOil has also followed the guidance under SAB Topic 5H wherein a gain on contributions to the joint venture is not recognised, however, a gain is recognised as a result of a change in economic interest.

Reconciliation to accounting principles generally accepted in the United States (cont’d)

InterOil will account for the joint venture using equity accounted method. In addition to the gain or loss recognised as part of the operations, InterOil will also recognise any difference between the Investment carried in its balance sheet and the underlying equity in net assets of the joint venture in the statement of operations and the investment balance will increase/decrease in line with this difference.

The adjustments to reflect the reversal of proportionately consolidated balances and take-up of equity accounted balances have been summarised below. Given below is the Midstream — liquefaction consolidated balance sheet and statement of operations under Canadian GAAP and U.S. GAAP. The statement of operations incorporates results for the six month period ended June 30, 2008. PNG LNG Inc. was a subsidiary of InterOil until the date of the Shareholder’s Agreement and has been proportionately consolidated subsequent to that date.

(7)	Income tax effect of adjustments
	The income tax effect of U.S. GAAP adjustments was a reduction to the future tax asset of $1,604,676 (year ended December 31, 2007 — $3,403,154) for the six month period ended June 30, 2008 due to a decrease in the loss carry-forwards. A corresponding decrease in the valuation allowance was recorded.
(8)	Non controlling interest
	The non-controlling interest movements are the result of the U.S. GAAP adjustments relating to the midstream operations described in point 1 above.

Recent Accounting Pronouncements

Fair value measurements

In September 2006, the FASB issued FAS 157 which defines fair value, establishes a framework for measuring fair value in U.S. GAAP, and expands disclosures about fair value measurements. The standard is effective for fiscal years beginning after November 15, 2007 and all interim periods within those fiscal years. The Company does not expect that the application of FAS 157 will have a material impact on the financial statements.

Fair Value Option for Financial Assets and Financial Liabilities

In February 2007, the FASB issued FAS 159 which permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. This Statement is expected to expand the use of fair value measurement, which is consistent with the Board’s long-term measurement objectives for accounting for financial instruments. This Statement is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007. The Company does not expect that the application of FAS 159 will have a material impact on the financial statements.

Business combinations

In December 2007, the FASB issued FAS 141 (revised 2007) to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. This Statement applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. This will have no impact unless the Company undertakes a business combination subsequent to adoption of this standard.

Non-controlling interests in consolidated financial statements

In December 2007, the FASB issued FAS 160. The objective of this Statement is to improve the relevance, comparability, and transparency of the financial information that a reporting entity provides in its consolidated financial statements by establishing accounting and reporting standards. It clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. This Statement changes the way the consolidated income statement is presented. It requires consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest. It also requires disclosure, on the face of the consolidated statement of income, of the amounts of consolidated net income attributable to the parent and to the noncontrolling interest. Previously, net income attributable to the noncontrolling interest generally was reported as an expense or other deduction in arriving at consolidated net income. This Statement applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. This will have no impact unless the Company undertakes a business combination involving a non-controlling interest subsequent to adoption of this standard.

Disclosures about derivative instruments and hedging activities

In March 2008, the FASB issued FAS 161. This statement requires enhanced disclosures about an entity’s derivative and hedging activities and thereby improves the transparency of financial reporting. Entities are required to provide enhanced disclosures about how and why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for under Statement 133 and its related interpretations, and how derivative

11

Reconciliation to accounting principles generally accepted in the United States (cont’d)

instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. The statement requires that objectives for using derivative instruments be disclosed in terms of underlying risk and accounting designation. This disclosure better conveys the purpose of derivative use in terms of the risk that the entity is intending to manage. Disclosing the fair values of derivative instruments and their gains and losses in a tabular format should provide a more complete picture of the location in an entity’s financial statements of both the derivative positions existing at period end and the effect of using derivatives during the reporting period. Disclosing information about credit-risk-related contingent features should provide information on the potential effect on an entity’s liquidity from using derivatives. This statement is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The Company does not expect that the application of FAS 161 will have a material impact on the financial statements.

Hierarchy of generally accepted accounting principles

In May 2008, the FASB issued FAS 162. This statement identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements by nongovernmental entities that are presented in accordance with the US GAAP. This statement is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles. The SEC approved the amendments on September 16, 2008. The Company does not expect that the application of FAS 161 will have a material impact on the financial statements.

Accounting for financial guarantee insurance contracts

In May 2008, the FASB issued FAS 163 which clarifies how FAS 60 applies to financial guarantee insurance contracts, including the recognition and measurement to be used to account for premium revenue and claim liabilities. The statement requires recognition of a claim liability prior to an event of default when there is evidence that credit deterioration has occurred in an insured financial obligation. The statement also required expanded disclosures about financial guarantee insurance contracts. This statement is effective for years beginning after December 15, 2008 and interim periods within those years, except for certain disclosure requirements which are effective for the first period (including interim periods) beginning after May 23, 2008. The Company does not expect that the application of FAS 163 will have any impact on the financial statements.
