Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On February 15, 2013, Hudson Technologies Company ("HTC"), a subsidiary of Hudson Technologies, Inc. (the "Registrant"), entered into a First Amendment to Revolving Credit, Term Loan and Security Agreement (the "Amendment") with PNC Bank, National Association ("PNC"), which amended HTC's existing credit, term loan and security agreement with PNC (the "Facility"). As a result of the Amendment, the Maximum Loan Amount (as defined in the Facility) has been increased from $27,000,000 to $40,000,000, and the Maximum Revolving Advance Amount (as defined in the Facility) has been increased from $23,000,000 to $36,000,000. In connection with the Amendment, each of the Registrant and its subsidiary, Hudson Holdings, Inc., entered into a Guarantors' Ratification in which they acknowledged that the obligations under the Facility (as amended) are secured by their existing guaranty and suretyship agreements (the "Guarantors' Ratification"). All other material terms of the Facility remain unchanged.

The Facility bears interest at a variable rate, and as of February 15, 2013, the Facility bears interest at the effective rate of 2.8%. At February 15, 2013, the total borrowings under the Facility were $17,645,787.

The foregoing description of the Amendment and related documents does not purport to be complete and is qualified in its entirety by reference to the Amendment, the $36,000,000 Amended and Restated Revolving Credit Note and the Guarantors' Ratification, which are filed as exhibits to this report and are incorporated herein by reference.
