of stockholders has been scheduled for June 27, 2013 (the &#147;Annual Meeting&#148;).&nbsp;
Because the date of the Annual Meeting has been changed by more than 30 days
from the date of the previous year's annual meeting of stockholders, the
deadline for shareholders to submit shareholder proposals for inclusion in the
Company&#146;s proxy statement and form of proxy to be distributed by the Board of
Directors in accordance with Rule 14a-8 under the Exchange Act will be the
close of business on May 24, 2013, which the Company believes is a reasonable
time before it expects to begin to print and send its proxy materials.&nbsp; Any
such proposal should be mailed to: Corporate Secretary, Plug Power Inc., 968

Item 1.01.       Entry into a Material Definitive
Agreement.
As previously reported on the
Current Report on Form 8-K filed on May 8, 2013, Plug Power Inc. (the
"Company") entered into a Securities Purchase Agreement (the "Purchase
Agreement"), dated as of May 8, 2013, with Air Liquide Investissements d'Avenir
et de Demonstration ("Air Liquide"). A copy of the Purchase Agreement was filed
with the Current Report on Form 8-K, filed on May 8, 2013, as
Exhibit 10.1.
On May 16, 2013, the Company
consummated the transactions contemplated by the Purchase Agreement, including
issuing 10,431 shares of the Company's Series C Redeemable Convertible
Preferred Stock, par value $0.01 per share (the "Series C Preferred Stock"),
and entering into a Registration Rights Agreement (the "Registration Rights
Agreement") with Air Liquide.  Under the Registration Rights Agreement, the
Company has agreed to register for resale all  shares of the Company's common
stock, par value $0.01 per share (the "Common Stock"), issued or issuable upon
conversion of shares of the Series C Preferred Stock and as a payment-in-kind
dividend on the shares of Series C Preferred Stock.  The foregoing summary is
qualified in its entirety by the full text of the Registration Rights Agreement,
a copy of which is filed herewith as Exhibit 10.1 and incorporated herein by
reference.
Item 5.03.       Amendments to Articles of Incorporation
or Bylaws; Change in Fiscal Year.
On May 16, 2013, the Company filed
a Certificate of Designations of Series C Redeemable Convertible Preferred
Stock with the Secretary of State of the State of Delaware establishing the
rights, preferences, privileges, qualifications, restrictions and limitations
relating to the Series C Preferred Stock. The Series C Preferred Stock  ranks
senior to the Common Stock with respect to rights upon the liquidation,
dissolution or winding up of the Company. The Series C Preferred Stock  is
entitled to receive dividends at a rate of 8% per annum payable in equal
quarterly installments in cash or in shares of Common Stock, at the Company's
option. The Series C Preferred Stock  is convertible into shares of Common Stock,
at a conversion price equal to $0.248794 per share, at Air Liquide's option,
(1) on or after May 8, 2014 or (2) upon any liquidation, dissolution or winding
up of the Company, any sale, consolidation or merger of the Company resulting
in a change of control, or any sale or other transfer of all or substantially
all of the assets of the Company.  The Series C Preferred Stock has customary
redemption rights at the election of either the Company or Air Liquide on or
after May 8, 2016 as well as weighted average anti-dilution protection.  The
Series C Preferred Stock  votes together with the Common Stock on an
as-converted basis on all matters, except as otherwise required by law. The
foregoing summary is qualified in its entirety by the full text of the Certificate
of Designations of Series C Redeemable Convertible Preferred Stock, a copy of
which is filed herewith as Exhibit 3.1 and incorporated herein by reference
Item 7.01.       Regulation FD Disclosure.
The Company issued a press
release announcing the consummation of the transactions contemplated by the
Purchase Agreement. A copy of the press release is furnished herewith as
Exhibit 99.1.

The information in this Item 7.01
of this Current Report on Form 8-K, including the information contained in
Exhibit 99.1, shall not be deemed "filed" for the purposes of Section 18 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise
subject to the liabilities under that Section. Furthermore, the information in
Item 7.01 of this Current Report on Form 8-K, including the information
contained in Exhibit 99.1, shall not be deemed to be incorporated by reference
into the filings of the Company under the Securities Act, or the Exchange Act,
except as shall be expressly set forth by specific reference in such a filing.
Item 8.01.       Other Events.
The Company's 2013 annual meeting
of stockholders has been scheduled for June 27, 2013 (the "Annual Meeting"). 
Because the date of the Annual Meeting has been changed by more than 30 days
from the date of the previous year's annual meeting of stockholders, the
deadline for shareholders to submit shareholder proposals for inclusion in the
Company's proxy statement and form of proxy to be distributed by the Board of
Directors in accordance with Rule 14a-8 under the Exchange Act will be the
close of business on May 24, 2013, which the Company believes is a reasonable
time before it expects to begin to print and send its proxy materials.  Any
such proposal should be mailed to: Corporate Secretary, Plug Power Inc., 968
Albany Shaker Road, Albany, New York 12110.  Such proposal must also comply
with the requirements as to form and substance established by the SEC for such
a proposal to be included in the proxy statement and form of proxy.
