ITEM 4. Changes in Registrant's Certifying Accountant

(a) On November 20, 2001, Plug Power Inc. (the "Company") dismissed
PricewaterhouseCoopers LLP as its independent accountants. The Company's Board
of Directors, upon recommendation of its Audit Committee, has approved another
independent public accounting firm, subject to such firm's normal client
acceptance processes and procedures, and the Company intends to file a Form 8-K
upon completion of this process.

(b) The reports of PricewaterhouseCoopers LLP on the Company's consolidated
financial statements for each of the two years in the period ended December 31,
2000 and 1999, did not contain any adverse opinion or disclaimer of opinion and
were not qualified or modified as to uncertainty, audit scope, or accounting
principles.

(c) During the two years in the period ended December 31, 2000, and the
subsequent interim period preceding the dismissal of PricewaterhouseCoopers LLP
on November 20, 2001, there were no disagreements with PricewaterhouseCoopers
LLP on any matters of accounting principles or practices, financial statement
disclosure, or auditing scope or procedures which, if not resolved to the
satisfaction of PricewaterhouseCoopers LLP, would have caused the firm to make
reference to the matter of the disagreement in their reports.

(d) During the two years in the period ended December 31, 2000, and the
subsequent interim period preceding the dismissal of PricewaterhouseCoopers LLP
on November 20, 2001, no reportable events occurred in connection with the
relationship between PricewaterhouseCoopers LLP and the Company.

(e) The Company has requested PricewaterhouseCoopers LLP to furnish a letter
addressed to the Securities and Exchange Commission stating whether it agrees
with the above statements. A copy of the letter is attached as Exhibit 16.1 to
this report.
