Explanatory Note

We have determined that, in certain cases, we did not comply with accounting principles generally accepted in the United States in the preparation of our 2005 and 2004 financial statements, and accordingly, we have restated the financial statements in our 2005 Annual Report on Form 10-K/A (Amendment No. 2).

As discussed more fully in Note 5, “Restatement of Financial Statements”, to the financial statements in Item 1 of this Form 10-Q/A (Amendment No. 1), the financial statements have been restated to classify our Series B Convertible Redeemable Preferred Stock outside of permanent equity. The restatement is consistent with guidance in Emerging Issues Task Force (“EITF”) No. D-98, Classification and Measurement of Redeemable Securities.

Pursuant to Regulation S-X, Article 10-01(a)(5), footnote disclosure which would substantially duplicate the disclosure contained in the most recent annual report to security holders or latest audited financial statements, such as a statement of significant accounting policies and practices, details of accounts which have not changed significantly in amount or composition since the end of the most recently completed year, and detailed disclosures prescribed by Rule 4-08 of the Regulation may be omitted. Certain disclosures that were previously presented in this Quarterly Report on Form 10-Q for the quarter ended March 31, 2006 are duplications of information previously disclosed in the aforementioned Annual Report on Form 10-K/A (Amendment No. 2) and, consequently, have been omitted from this Form 10-Q/A (Amendment No. 1).

The information contained in the Liquidity and Capital Resources section is as of May 15, 2006. Please see our Quarterly Report for the quarter ended June 30, 2006 for more current information.

Heartland Oil and Gas Corp.

Notes to Financial Statements

Note 1 - Organization, Operations and Significant Accounting Policies

Organization

Heartland Oil and Gas Corp. was incorporated in Nevada on August 11, 2000. Our principal business is exploration and development of oil and gas property in the United States. Through December 31, 2005, we were in the exploration stage and had not generated significant revenue from operations. We first sold natural gas in February 2006 so we are no longer an exploration stage company.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Heartland Oil and Gas Corp. and its wholly owned entities. We have eliminated all significant intercompany balances and transactions in consolidation.

The accompanying financial statements are unaudited and include, in our opinion, all adjustments, consisting of only normal recurring adjustments, necessary for fair presentation. The financial statements should be read in conjunction with our audited financial statements and the related notes included in our December 31, 2005, Form 10-K/A (Amendment No. 2). The accompanying financial statements are interim financial statements prepared in accordance with accounting principles generally accepted in the United States and are stated in U.S. dollars.

Stock-Based Compensation

Effective January 1, 2006, we account for stock-based compensation based on the fair value of the options at the grant date as provided by FASB Statement 123(R), Stock-Based Compensation. We record compensation expense for all share-based awards granted, and for awards modified, repurchased or cancelled. We will recognize compensation expense for outstanding awards for which the requisite service had not been rendered as of January 1, 2006, over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under FASB Statement 123, adjusted for expected forfeitures. We have adopted Statement 123(R) using a modified prospective application. Prior to January 1, 2006 we recognized employee compensation expense for our stock options plan using the intrinsic value method of accounting. Under the terms of the intrinsic value method, compensation expense was the excess, if any, of the quoted market price of the stock at the grant date, over the amount an employee must pay to acquire the stock. Under our Amended 2005 Stock Option Plan, we may grant up to a maximum of 4,000,000 shares of common stock to key employees and consultants. The options granted under the plan vest over four years except as stated otherwise in the individual grants, and are for a term not exceeding 10 years.

For the period ended March 31, 2006, we expensed the fair value of options granted to non-employees, employees, officers and directors. For the period ended March 31, 2005 we expensed the fair value of options granted to non-employees and disclosed the pro forma fair value of options granted to employees, officers and directors.

Heartland Oil & Gas Corp.

Notes to Financial Statements

Had we measured compensation cost based on the fair value of the options at the grant date for the quarter ended March 31, 2005, consistent with the method prescribed by Statement 123, our net loss and loss per common share would have been increased to the pro forma amounts indicated below:

	Quarter Ended March 31, 2005
Net loss, as reported	$	(10,446,723	)
Add: Stock-based employee compensation expense included in reported net income, net of related tax effects		257,880
Deduct: Total stock-based employee compensation expense determined under fair-value-based method for all awards, net of related tax effects		(354,924	)
Pro forma net loss	$	(10,543,767	)
Loss per share:
Basic and diluted earnings (loss) per common share
As reported	$	(0.22	)
Pro forma	$	(0.23	)

The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions, are fully transferable, and are not subject to trading restrictions or blackout periods. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, it is our opinion that the existing models do not necessarily provide a reliable single measure of the fair value of our employee stock options.

Reclassifications

We have reclassified certain data in the financial statements of the prior periods to conform to the current period presentation.

Note 2 - Going Concern

We have incurred significant losses since inception and had no revenue from inception to December 31, 2005. As of March 31, 2006, we have limited financial resources. Our continuation is dependent upon our ability to raise additional capital, to exploit our mineral holdings, and to generate sufficient revenue from our planned operations to enable us to attain and maintain profitable operations. We sold natural gas for the first time in February, 2006.

The issuance of additional equity securities by us could result in significant dilution in the equity interests of our current stockholders. Obtaining commercial loans, assuming those loans would be available, will increase our liabilities and future cash commitments.

We cannot assure that we will be able to obtain further funds required for our continued operations, that additional financing will be available to us when needed or, if available, that we can obtain it on commercially reasonable terms. If we are not able to obtain the additional financing on a timely basis, we may be unable to conduct our operations as planned, and we may not be able to meet our other obligations as they become due. In such event, we would be forced to scale down or perhaps even cease our operations.

Note 3 - Asset Retirement Obligations

	Quarter Ended March 31, 2006			Year Ended December 31, 2005
Beginning asset retirement obligations	$	671,140		$	562,619
Site reclamation cost paid		(502,109	)		—

Accretion		4,539			42,763
Total asset retirement obligations	$	212,753		$	671,140

Note 4 - Related Party Transactions

The amount due to related parties represented non-interest bearing expense reimbursements to directors and officers, which were subsequently paid.

We entered into management consulting agreements dated October 1, 2004, as amended, with a director for the payment of management fees of $7,500CN per month, and with our former President for the payment of $16,666 per month, respectively, each for a term of one year. We also entered into a consulting agreement for services on an hourly basis with our contract CFO. For the three months ending March 31, 2006, he was paid $31,395 for services rendered.

Effective January 1, 2006, we approved the payment of Director’s fees for non-employee Directors at the rate of $200 per hour.

During the three-months ended March 31, 2006 and March 31, 2005, we incurred $59,830 and $84,575, respectively, in management and consulting fees to our directors and officers.

Note 5 - Restatement

We have determined that, in certain cases, we did not comply with accounting principles generally accepted in the United States in the preparation of our 2004 consolidated financial statements, and for the period from inception (August 11, 2000) through December 31, 2005, and, accordingly, we have restated the 2005 annual financial statements in our Annual Report on Form 10-K/A (Amendment No. 2).

Consistent with the restatement of the annual financial statements, the consolidated interim financial statements have been restated to reflect the Company’s Series B Convertible Redeemable Preferred Stock as a separate line item outside of permanent equity. The restatement is consistent with guidance in Emerging Issues Task Force (“EITF”) No. D-98, Classification and Measurement of Redeemable Securities.

Pursuant to Regulation S-X, Article 10-01(a)(5), footnote disclosure which would substantially duplicate the disclosure contained in the most recent annual report to security holders or latest audited financial statements, such as a statement of significant accounting policies and practices, details of accounts which have not changed significantly in amount or composition since the end of the most recently completed fiscal year, and detailed disclosures prescribed by Rule 4-08 of the Regulation may be omitted. Certain disclosures that were previously presented in this Quarterly Report on Form 10-Q for the three months ended March 31, 2006 were duplications of information previously disclosed in the aforementioned Annual Report on Form 10-K/A (Amendment No. 2) and, consequently, have been omitted from this Form 10-Q/A (Amendment No. 1).
