INDEX TO CONSOLIDATED FINANCIAL STATEMENTS

Report of Independent Auditors

The Member

Panhandle B Member 2 LLC

We have audited the accompanying consolidated financial statements of Panhandle B Member 2 LLC (the Company), which comprise the consolidated statement of financial position as of December 31, 2013, and the related consolidated statement of operations and comprehensive loss, changes in member’s capital, and cash flow for the period from March 1, 2013, the date of inception, to December 31, 2013, and the related notes to the consolidated financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in conformity with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free of material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

1. Business

Panhandle B Member 2 LLC (Panhandle B Member 2 or the Company), a Delaware limited liability company, was formed on March 1, 2013. Panhandle B Member 2 is a wholly-owned subsidiary of Panhandle B Holdco 2 LLC (the Member), a wholly-owned, indirect subsidiary of Pattern Energy Group LP (Pattern Development). Panhandle Wind Holdings 2 LLC owns 100% of Pattern Panhandle Wind 2 LLC (Panhandle Wind 2).

Panhandle Wind 2 is currently constructing a 182 megawatt (MW) (unaudited) capacity wind electricity generating plant (the Facility), which utilizes 79 Siemens Energy Inc. (Siemens) turbines (unaudited). The Facility is expected to commence full commercial operations in the fourth quarter of 2014 (COD). The Facility will deliver 100% of the electricity it generates into the Texas wholesale spot market managed by the Electric Reliability Council of Texas (ERCOT) of which approximately 80% of the expected electricity output will be sold to Morgan Stanley Capital Group Inc. (Morgan Stanley Capital) under a physical power sales agreement (the Electricity Sales Agreement) for a term of approximately 12 years, which commences on February 1, 2015. Any additional electricity produced will be sold to ERCOT at spot market prices. The Electricity Sales Agreement requires that electricity be delivered at specified hourly levels at a fixed price and at a delivery location separate from the Facility’s interconnection point. Prior to February 1, 2015, the Facility will sell its electricity to ERCOT at spot market prices.

The Member shall not be required to make additional capital contributions, or have any personal liability with respect to the liabilities or the obligations of the Company.

In December 2013, Pattern Energy Group Inc., which is a publicly traded company in which Pattern Development retains a controlling interest, agreed to acquire the Company from Pattern Development at COD, subject to normal conditions precedent.

2. Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The accompanying consolidated financial statements are presented using United States generally accepted accounting principles (U.S. GAAP). Upon consolidation, all intercompany accounts and transactions are eliminated. The consolidated financial statements include the accounts and operations of the Company’s and its wholly-owned subsidiaries. The preparation of U.S. GAAP basis consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements and the reported amounts of assets and liabilities, and to disclose contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Because the use of estimates is inherent in the financial reporting process, actual results could differ from those estimates.

2. Summary of Significant Accounting Policies (continued)

The Company has no items of other comprehensive income and, therefore, net loss and net and comprehensive loss are equal.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash in banks and highly liquid investments with original maturities of three months or less.

Deposit

Deposit includes a deposit made to Morgan Stanley Capital as security under the Electricity Sales Agreement. The deposit will remain in place until COD.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and cash equivalents with high-quality institutions.

Deferred Financing Costs

Financing costs incurred in connection with obtaining construction and term financing are deferred and amortized over the lives of the respective loans using the effective-interest method. Amortization of deferred financing costs is capitalized to construction in progress prior to COD and recorded as interest expense in the consolidated statement of operations and comprehensive loss following COD.

Turbine Advances

Turbine advances represent amounts advanced to the turbine supplier for the manufacture of wind turbines in accordance with the turbine supply agreement and for which the Company has not taken title. Turbine advances are reclassified to construction in progress when the Company takes legal title to the related turbines and are reclassified to property, plant and equipment when the Facility achieves commercial operations. Depreciation does not commence until the project enters commercial operations and the Facility is placed in service.

2. Summary of Significant Accounting Policies (continued)

Construction in Progress

Construction in progress represents the accumulated costs of projects in construction. Construction costs include turbines for which the Company has taken legal title, civil engineering, electrical and other related costs. Other capitalized costs include reclassified deferred development costs, amortization of intangible assets, amortization of deferred financing costs, capitalized interest and other costs required to place a project into commercial operations.

Construction in progress is reclassified to property, plant and equipment when the project begins commercial operations.

Asset Retirement Obligation

The Company records an asset retirement obligation for the estimated cost of decommissioning the turbines, removing above-ground installations, and restoring the site at a date that is 20 years from COD.

Income Taxes

The accompanying consolidated financial statements of the Company reflect no provision or liability for income taxes because profits and losses of the Company are allocated to the Member and are includable in the income tax return of the Member.

Income and losses for tax purposes may differ from the consolidated financial statement amounts and the Member’s capital reflected in the accompanying consolidated financial statements does not necessarily represent the Member’s tax basis.

Revenue Recognition

The Facility will sell the electricity it generates to Morgan Stanley Capital under the terms of the Electricity Sales Agreement, and to ERCOT. Revenue will be recognized as electricity is delivered.

Fair Value of Financial Instruments

The fair values of the Company’s financial instruments (including such items in the consolidated financial statement captions as cash and cash equivalents, prepaid expenses and other current assets, deposits, related party payable, accounts payable and other accrued liabilities, accrued construction costs and asset retirement obligation) approximate their carrying or contract values based on their nature and terms. The Company’s debt is variable rate, and its carrying value approximates fair value.

The Loan and the Energy Loan are variable rate loans, and the Company’s interest rate at December 31, 2013 was 2.0% based on the LIBO rate in effect at December 31, 2013 plus a margin of 1.75%. The Company pays a 1.75% letter of credit fee on the outstanding portion of the letter of credit. As of December 31, 2013, the $6.0 million letter of credit has been issued. For the period ended December 31, 2013, the Company has incurred a total of approximately $92,000 in interest expense and letter of credit fees, of which $73,000 has been capitalized to construction in progress on the statement of financial position and of which $19,000 has been recorded in interest expense on the statement of operations and comprehensive loss.

8. Risk Management

The Company’s Facility is located in an area of Texas that is subject to tornados, and it could potentially be subject to damages from these natural events. To mitigate the risk, the Company maintains property damage insurance coverage, which it believes is adequate.

9. Commitments and Contingencies

Panhandle Wind 2 entered into the Electricity Sales Agreement with Morgan Stanley Capital. The Facility will deliver 100% of the electricity it generates into the Texas wholesale spot market managed by ERCOT of which approximately 80% of the expected electricity output will be sold to Morgan Stanley Capital under the Electricity Sales Agreement for a term of approximately 12 years, which commences on February 1, 2015. Any additional electricity produced will be sold to ERCOT at spot market prices. The Electricity Sales Agreement requires that electricity be delivered at specified hourly levels at a fixed price and at a delivery location separate from the Facility’s interconnection point. Prior to February 1, 2015, the Facility will sell its electricity to ERCOT at spot market prices.

Under the terms of the Electricity Sales Agreement, should Panhandle Wind 2’s net revenue fall short of the specified monthly delivery quantities at the fixed electricity price for a monthly period, the Company will be able to borrow such shortfall from Morgan Stanley Capital up to a cumulative amount of $25.0 million. In addition, should Panhandle Wind 2’s net revenue be in excess of the specified monthly delivery quantities at the fixed electricity price for a monthly period, such excess will be first used to repay any amounts borrowed from Morgan Stanley Capital.

As collateral for the Electricity Sales Agreement, Morgan Stanley has issued a guarantee to the Company to guaranty Morgan Stanley Capital’s performance under the Electricity Sales Agreement. In addition, the Company has pledged the Facility and Panhandle Wind 2’s other assets, its contractual rights, and cash as collateral for its performance under the Electricity Sales Agreement after COD and has provided a $24.0 million deposit to Morgan Stanley Capital until COD.

Panhandle Wind 2 entered into an agreement for the supply of 79 Siemens wind turbine generators and other specified equipment for the construction of the Facility. Panhandle Wind 2 also entered into an agreement for the assembly and erection of the wind turbine generators and construction of the Facility, including the procurement of the materials and other equipment necessary to complete the construction of the Facility. Our remaining total commitments on these contracts is $138.0 million.
