<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">On August 9, 2018, Hudson Technologies, Inc. (the &ldquo;Company&rdquo;)
filed a Notification of Late Filing on Form 12b-25 (the &ldquo;Form 12b-25&rdquo;) in which it reported that the Company was operating
under a waiver and amendment to its term loan credit and security agreement with U.S. Bank National Association, as agent, and
the term loan lenders (&ldquo;Term Loan&rdquo;). The prior waiver ran through August 14, 2018, and discussions were continuing
with respect to an amendment of the Term Loan&rsquo;s existing total leverage ratio financial covenant and certain other terms,
which the Company previously expected to complete on or before August 14, 2018. As a result of the potential balance sheet impact
of foregoing discussions, the Company was not in a position to file its Quarterly Report on Form 10-Q for the quarter ended June
30, 2018 (the &ldquo;Q2 10-Q&rdquo;) on a timely basis.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">Also, as previously reported, on August 14, 2018, Hudson Technologies
Company (&ldquo;HTC&rdquo;), an indirect subsidiary of the Company, and HTC&rsquo;s affiliates Hudson Holdings, Inc. and Aspen
Refrigerants, Inc. (formerly known as Airgas-Refrigerants, Inc.), as borrowers (collectively, the &ldquo;Borrowers&rdquo;), and
the Company as a guarantor, entered into a Waiver and Second Amendment to Term Loan Credit and Security Agreement (the &ldquo;Second
Amendment&rdquo;) with U.S. Bank National Association, as agent, and the term loan lenders. The Second Amendment superseded interim
waivers and amended the Term Loan Credit and Security Agreement dated October 10, 2017 (the &ldquo;Term Loan Agreement&rdquo;)
to waive compliance with the existing total leverage ratio financial covenant at June 30, 2018, as previously amended. The Second
Amendment also provided that on October 15, 2018, the Company and the Borrowers were required to provide a certificate setting
forth the total leverage ratio as of the four fiscal quarter period ending September 30, 2018 and the failure to maintain, as of
the end of such four fiscal quarter period, the total leverage ratio required under the Term Loan Agreement, or deliver the aforementioned
certificate would, in each case, constitute an immediate event of default under the Term Loan Agreement.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">On October 15, 2018, the Borrowers, and the Company as a guarantor,
entered into an Extension Letter (the &ldquo;Extension Letter&rdquo;) with U.S. Bank National Association, which extended the delivery
deadline of the above referenced compliance certificate to November 14, 2018. The Extension Letter also required the Company and
the Borrowers to deliver to Lenders by October 31, 2018 a financial model in form and substance reasonably satisfactory to the
Lenders and provides that the failure to deliver such model by October 31, 2018 shall constitute an immediate event of default
under the Term Loan Agreement. The financial model was timely delivered to the Lenders on October 31, 2018.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">The Second Amendment, as amended by the Extension Letter, while
providing a further waiver, does not resolve the potential balance sheet impact described above and the Company, the Borrowers
and the Lenders are continuing discussions with respect to a further amendment of the Term Loan&rsquo;s existing total leverage
ratio financial covenant and certain other terms not later than November 14, 2018. There can be no assurance that the Company will
reach timely agreement with respect to a further amendment on acceptable terms or at all. Failure to reach such an agreement could
have a material adverse effect on the Company&rsquo;s financial position.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0">The Company is working diligently to resolve these matters and management
currently believes that the Company will be in a position to file its Q2 10-Q and its quarterly report on Form 10-Q for the quarter

30, 2018, the Company&rsquo;s revenues were $40.5 million, an increase of 64% compared to $24.7 million in the comparable
2017 period. Revenues for the 2018 period included revenues from Aspen Refrigerants, Inc. (&ldquo;ARI&rdquo;) which was
acquired in October 2017. For the nine months ended September 30, 2018, the Company&rsquo;s revenues were $140.8 million, an
increase of 22% compared to $115.8 million in the comparable 2017 period. Revenues for the 2018 period included revenues from
ARI. Due to the uncertainty associated with the matters described below, together with the potential impact of the annual
goodwill impairment assessment, the Company is not yet in a position to provide preliminary net income data for the third
fiscal quarter and the nine months ended September 30, 2018.</P>

the Borrowers and the Lenders are continuing discussions with respect to a further amendment of the Term Loan&rsquo;s existing
total leverage ratio financial covenant and certain other terms not later than November 14, 2018.</P>

a timely basis. The Company is working diligently to resolve these matters and management currently believes that the Company will
be in a position to file the aforementioned Q3 10-Q by November 21, 2018.</P>
