ITEM 4. Changes in Registrant's Certifying Accountant

(a)  On November 28, 2001, Plug Power Inc. (the "Company") filed a Form 8-K
report with the Securities and Exchange Commission disclosing that, on November
20, 2001, the Company dismissed PricewaterhouseCoopers LLP as its independent
accountants.

(b)  The Company engaged KPMG LLP as the Company's independent public
accountants effective December 3, 2001. The Company's Board of Directors, upon
recommendation of its Audit Committee, approved the engagement of KPMG. During
the Company's two most recent fiscal years and the subsequent interim period
prior to engaging KPMG, neither the Company nor anyone on its behalf consulted
with KPMG regarding either (i) the application of accounting principles to a
specific transaction, either completed or proposed, or the type of audit opinion
that might be rendered on the Company's financial statements, and neither a
written report nor oral advice was provided to the Company by KPMG that was an
important factor considered by the Company in reaching a decision as to any
accounting, auditing or financial reporting issue; or (ii) any matter that was
either the subject of a disagreement, as that term is defined in Item
304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of
Regulation S-K, or a reportable event, as that term is defined in Item
304(a)(1)(v) of Regulation S-K.

amended, the registrant has duly caused this report to be filed on its behalf by
the undersigned hereunto duly authorized.
