To the Board of Members

Saddle Butte Pipeline, LLC

Durango, Colorado

We have audited the accompanying combined balance sheets of Saddle Butte Assets, LLC and Saddle Butte Fort Berthold Gathering, LLC as of December 31, 2012, 2011 and 2010, and the related combined statements of operations, members’ equity, and cash flows for each of the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present fairly, in all material respects, the combined financial position of Saddle Butte Assets, LLC and Saddle Butte Fort Berthold Gathering, LLC as of December 31, 2012, 2011 and 2010, and the results of its operations and its cash flows for each of the years then ended in conformity with U.S. generally accepted accounting principles.

SADDLE BUTTE ASSETS, LLC AND SADDLE BUTTE FORT BERTHOLD GATHERING, LLC

NOTES TO COMBINED FINANCIAL STATEMENTS

1. ORGANIZATIONAND SIGNIFICANT ACCOUNTING POLICIES:

Business – Saddle Butte Assets, LLC and Saddle Butte Fort Berthold Gathering, LLC, combined, are a midstream natural gas and crude oil gathering pipeline and processing entity. Saddle Butte Assets, LLC and Saddle Butte Fort Berthold Gathering, LLC gather the natural gas and crude oil at the wellhead and transport the products to their crude terminal and gas processing plant in McKenzie County, North Dakota. The operations of the pipeline and facilities began in 2011. Saddle Butte Assets, LLC and Saddle Butte Fort Berthold Gathering, LLC were formed in 2008.

Basis of Presentation – The accompanying combined financial statements include the accounts of Saddle Butte Assets, LLC, and Saddle Butte Fort Berthold Gathering, LLC, herein collectively referred to as the “Company” or “Saddle Butte.” All significant intercompany accounts and transactions have been eliminated in combination.

Liquidity – At December 31, 2012, the Company has had net income since inception of approximately $6.6 million and is able to fund current operations through generated cash flow. The continued capital expansion of the system, including contracts already entered into, will require contributions to fund those expansions (see Note 2).

Use of Estimates – The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosures of contingent assets and liabilities. Actual results could differ from those estimates.

Cash and Cash Equivalents – Cash and cash equivalents consist of highly liquid investments, with original maturities of three months or less. From time to time, these cash accounts may exceed federally insured limits.

Gas Gathering and Processing Receivable – The Company accrues for revenue generated from the sales of residue natural gas and natural gas liquids that are gathered, compressed and processed on its gathering system. Management regularly reviews the gas gathering and processing receivable amounts for collectability and records its allowance for uncollectible receivables under the specific identification method. The Company recorded no allowance for uncollected receivables at December 31, 2012, 2011 or 2010.

The Company currently has gathering and processing contracts with ten producers, which account for all the revenue and receivables from these activities.

NOTES TO COMBINED FINANCIAL STATEMENTS

Other Receivables and Deferred Revenue – During 2012 and 2011, the Company constructed extended facilities for the producers connected to the gathering system. The construction activities were performed in accordance with the gathering contracts in place with the various producers. The cost of the facilities is billed as incurred at a rate of the Company’s cost plus an agreed-upon percentage margin. The progress billings resulted in an other receivable at December 31, 2012 and 2011 of $19.0 million and $16.7 million, respectively, and deferred revenue at December 31, 2012 and 2011 of $1.3 million and $2.1 million, respectively, which represents the agreed-upon percentage margin. Deferred revenue will be recognized when construction is complete. The Company has not recorded an allowance for uncollected receivables from these construction projects. These projects are with three producers.

Fair Value of Financial Instruments – The Company’s financial instruments consist of cash and trade payables. The carrying value of cash and cash equivalents and trade payables are considered to be representative of their fair market value, due to the short maturity of these instruments.

Pipeline Inventory – Inventory consists of steel pipe, valves, fittings and materials which will be used on the construction of pipeline and gathering systems in North Dakota. These goods are valued at the lower of cost or market and no impairment has been recorded as of December 31, 2012, 2011 and 2010.

Property and Equipment –Property and equipment consists of all costs incurred for the construction of an oil and gas gathering and transportation system, a 40,000 Mcf/d gas processing plant and a 70,000 barrel crude terminal.

Renewals and betterments, which substantially extend the useful lives of the assets, are capitalized. All costs necessary to place an asset into operation are capitalized. Maintenance and repairs are expensed when incurred. Property and equipment is generally depreciated using the straight-line method over 3 to 20 years depending on the type of asset. When property is retired or otherwise disposed of, the cost and accumulated depreciation are removed from appropriate accounts and any gain or loss is included in income.

The Company evaluates impairment of its property and equipment to determine if the carrying value is recoverable based upon the undisputed future cash flows. If it is not recoverable, an impairment is recorded for the difference between the carrying value and the fair value of the asset. Based upon this evaluation, no impairments were recorded at December 31, 2012, 2011 and 2010.

Construction in Progress – Costs incurred for construction of oil and gas gathering and transportation systems in process and not operational are included in the account. No depreciation is recorded for these assets as they have not been placed in operations as of December 31, 2012, 2011 or 2010.

Asset Retirement Obligations – The Company accounts for asset retirement obligations by recording the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred, if a reasonable estimate of fair value can be made. The Company believes that a reasonable estimate of any asset retirement obligation cannot be made at this time.

SADDLE BUTTE ASSETS, LLC AND SADDLE BUTTE FORT BERTHOLD GATHERING, LLC

NOTES TO COMBINED FINANCIAL STATEMENTS

Revenue Recognition – The Company generates its revenue from natural gas gathering, compression and processing, and the transportation of crude oil. The Company provides services under a fee-based arrangement.

Under fee-based arrangements, the Company receives a fee for gathering, processing and compression of natural gas and transportation of crude oil. The revenue the Company earns from these arrangements is generally directly related to the volume of crude oil and natural gas that flows through the Company’s systems and facilities and is not directly dependent on commodity prices. Revenues are reported on a gross basis in the combined statements of operations, as the Company takes custody of the product at the producer’s wellhead and incurs the risk of loss until it is sold at the terminal station.

The terms of the Company contracts vary based on gas quality conditions, the competitive environment when the contracts are signed, and customer requirements.

Gas volumes received may be different from equivalent gas volumes delivered, resulting in gas imbalances. Gas imbalances as of December 31, 2012, 2011 and 2010 were immaterial.

Income Taxes – The Company is a Limited Liability Company (LLC), therefore, no income tax provision is included in the accompanying combined financial statements. Any taxable income of the Company is reported in the respective tax returns of the Company members.

The Company has no significant uncertain tax positions in 2012, 2011 or 2010. The Company’s policy is to recognize accrued interest related to unrecognized tax benefits in interest expense, and to recognize tax penalties in operating expense. As of December 31, 2012, the Company made no provision for interest or penalties related to uncertain tax positions. The Company files income tax returns in the U.S. federal jurisdiction and various states. There are currently no federal or state income tax examinations underway for these jurisdictions and tax returns for the periods from 2009 to 2012 are still open to examination.

Share-Based Payments – The Company accounts for member unit options where the measurement and recognition of compensation expense for all share-based payment awards to members and employees is based on estimated fair values.

Reclassifications – Certain prior year balances have been reclassified to conform to current year presentation. Such reclassifications had no impact on net loss or members’ equity.

New Accounting Pronouncements– In April 2011, the Financial Accounting Standards Board (FASB) issued new guidance to achieve common fair value measurement and disclosure requirements between U.S. generally accepted accounting principles and International Financial Reporting Standards. This new guidance amends current fair value measurement and disclosure guidance to include increased transparency around valuation inputs and investment categorization. This new guidance is effective for fiscal years and interim periods beginning after December 15, 2011. The Company does not believe its adoption of the new guidance will have an impact on its consolidated financial statements.
