EXHIBIT 99.2

On April 3, 2007, Plug Power Inc. (the “Company”) completed the acquisition of Cellex Power Products, Inc. (“Cellex”). The unaudited pro forma condensed combined financial data presented below is derived from the historical consolidated financial statements of the Company and the historical consolidated financial statements Cellex. The unaudited pro forma condensed combined balance sheet information is presented on an as adjusted basis as if the Cellex acquisition had occurred on December 31, 2006. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2006 combines the Company’s historical audited consolidated statement of operations for the year then ended with Cellex’s historical audited statement of operations for the year then ended. The unaudited pro forma condensed combined statements of operations give effect to the acquisition as if it had occurred on January 1, 2006. The Company believes this information is important in evaluating the future operations and impact of the Cellex acquisition.

The unaudited pro forma condensed combined financial statements contained in this report use the purchase method of accounting, with the Company treated as the acquirer. The purchase price for the Cellex acquisition was approximately $45.9 million. The pro forma adjustments are based on currently available information and upon assumptions that the Company believes are reasonable under the circumstances. A final determination of the allocation of the purchase price to the assets acquired and the liabilities assumed has not been made, and the allocation reflected in the unaudited pro forma condensed combined financial statements should be considered preliminary and is subject to the completion of a more comprehensive valuation of the assets acquired and liabilities assumed. The final allocation of purchase price could differ from the pro forma allocation included herein. Amounts preliminarily allocated to intangible assets and goodwill may change significantly, and amortization methods and useful lives may differ from the assumptions that have been used in this unaudited pro forma condensed combined financial information, any of which could result in a material change in depreciation and amortization expense.

You should read the following pro forma statements in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the financial statements and related notes contained in the Company’s annual report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2006.

The unaudited pro forma condensed combined financial statements are provided for illustrative purposes only. They do not purport to represent what the results of operations and financial position of the Company would have been had the Cellex acquisition actually occurred as of the dates indicated, and they do not purport to project or predict the future results of operations or financial position of the Company.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1. Basis of Presentation

On April 3, 2007, the Company completed the acquisition of Cellex Power Products, Inc. (Cellex), in a transaction accounted for using the purchase method of accounting in accordance with Statement of Financial Accounting Standards No. 141 (“ SFAS 141 “), Business Combinations .

The preliminary estimate total purchase price is as follows (in thousands):

Cash paid for Cellex	$	45,000
Estimated direct transaction costs		909
Total preliminary purchase price	$	45,909

Under the purchase method of accounting, the total purchase price as shown in the table above is allocated to Cellex’s tangible and intangible assets based on their fair values as of the acquisition date. The preliminary estimated purchase price has been allocated based on the preliminary estimates that are described in the introduction to these unaudited pro forma condensed combined financial statements.

The allocation of the preliminary purchase price is as follows (in thousands)

Cash and cash equivalents	$	10,381
Accounts receivable		2
Prepaid expenses and other assets		81
Government assistance receivable		708
Property and equipment		254
Identifiable intangibles and goodwill (unallocated purchase price)		36,654	*
Accounts payable and accrued expenses		(619	)
Other liabilities		(1,552	)
Total cash purchase price	$	45,909

* Includes the excess of the purchase price over the estimated fair value of assets and liabilities assumed.

The pro forma does not reflect amortization of the unallocated purchase price or in-process research and development costs since a third-party valuation has not been completed. Any allocation of unallocated purchase price to limited life intangible assets will result in amortization expense which will increase net loss. Any allocation to in-process research and development costs will be written-off as a nonrecurring charge and increase the net loss in the Company’s 2007 statement of operations.

2. Pro Forma Adjustments

Pro forma adjustments are necessary to reflect the estimated purchase price and to reflect amounts related to Cellex’s net tangible and intangible assets at an amount equal to the preliminary estimate of their fair values.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

There were no intercompany balances or transactions between the Company and Cellex as of the dates for the periods of these pro forma condensed combined financial statements.

The Company has not identified any pre-acquisition contingencies where the related asset, liability or impairment is probable and the amount of the asset, liability or impairment can be reasonably estimated. Prior to the end of the purchase price allocation period, if information becomes available which would indicate it is probable that such events have occurred and the amounts can be reasonably estimated, such items will be included in the purchase price allocation.

The pro forma adjustments included in the unaudited pro forma condensed combined financial statements are as follows:

a) Represents the total cash purchase price in connection with the Cellex acquisition.

b) Represents the estimated goodwill and intangible assets associated with the Cellex acquisition.

c) Equity accounts eliminated in purchase accounting including preferred shares, common shares, and accumulated deficit.

d) Includes the following: the gain on the Cellex reorganization ($38,619,524) has been eliminated as the acquisition is assumed to occur on January 1, 2006. Additionally, the Canadian refundable investment tax credits ($318,262) earned in 2006 have been eliminated as a U.S. controlled company would not be entitled to receive such amounts.

3. Foreign Currency Translation

The audited consolidated financial statements of Cellex as of and for the year ended December 31, 2006 were stated in Canadian dollars. For purposes of pro forma presentation these statements have been translated into United States dollars. The balance sheet was translated using the exchange rate at the close of business on December 31, 2006 and the statement of operations was translated using the average exchange rate for the year ended December 31, 2006.
