# OUTSTANDING STOCK AND VOTING RIGHTS

Only shareholders of record at the close of business on April 18, 2018 (the “Record Date”) are entitled to notice of and to vote at the Annual Meeting. As of the Record Date, there were issued and outstanding 42,403,140 shares of the Company’s common stock, par value $.01 per share (“Common Stock”), the only class of voting securities of the Company. Each share of Common Stock entitles the holder thereof to one vote on each matter submitted to a vote at the Annual Meeting.

# VOTING PROCEDURES

Directors will be elected by a plurality of the votes cast by the holders of Common Stock in person or represented by proxy at the Annual Meeting, provided a quorum is present at the meeting. Therefore, the nominees receiving the greatest number of votes cast at the meeting will be elected as directors of the Company. Proposals 2, 3, 4 and 5 will be decided by the majority of the votes cast by the holders of the Common Stock in person or represented by proxy at the Annual Meeting, provided a quorum is present at the meeting. A quorum will be present at the Annual Meeting if the holders of a majority of the outstanding shares of Common Stock as of the Record Date are present in person or represented by proxy. Votes will be counted and certified by one or more Inspectors of Election who are expected to be employees of Continental Stock Transfer & Trust Company, the Company’s transfer agent.

In accordance with applicable law, abstentions and “broker non-votes” (i.e., proxies from brokers or nominees indicating that such persons have not received instructions from the beneficial owners or other persons entitled to vote shares as to a matter with respect to which the brokers or nominees do not have discretionary power to vote) will be treated as present for purposes of determining the presence of a quorum. Based upon the requirements of the law of the State of New York and the Certificate of Incorporation and By-laws, as amended (the “By-laws”), of the Company, “votes cast” at a meeting of shareholders by the holders of shares entitled to vote are determinative of the outcome of each matter to be voted on. Failures to vote, broker non-votes and abstentions will not be considered “votes cast” and will therefore have no effect on the outcome.

1

Proxies will be voted in accordance with the instructions thereon. If no instructions are given, the proxies will be voted “for” the director nominees and “for” the other proposals set forth herein and in the discretion of the indicated proxies upon such other business as may properly come before the meeting. Proxies may be revoked as noted above.

# PROPOSAL 1
ELECTION OF FOUR DIRECTORS TO THE BOARD OF DIRECTORS

The Company’s By-laws currently provide that the Board is divided into two classes, with each class to have a term of two years (the term of each class expiring in alternating years) and is to consist, as nearly as possible, of one-half of the number of directors constituting the entire Board. The By-laws provide that the number of directors shall be fixed by the Board but in any event, shall be no less than five (5) (subject to decrease by a resolution adopted by the shareholders).

At the Annual Meeting a class of four directors will be elected to a two-year term expiring at the Annual Meeting of Shareholders to be held in 2020. Messrs. Dominic J. Monetta, Richard Parrillo, Eric A. Prouty and Kevin J. Zugibe are the nominees for a two-year term expiring at the Annual Meeting of the Shareholders to be held in 2020.

Messrs. Vincent P. Abbatecola, Brian F. Coleman and Otto C. Morch will not stand for election at the Annual Meeting because their respective terms expire at the Annual Meeting of Shareholders to be held in 2019.

Proxies will be voted for the nominees named below, unless authority is withheld. Should any nominee not be available for election, proxies will be voted for such substitute nominee as may be designated by the Board. Each of the nominees has indicated to the Board that he will be available and is willing to serve.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE ELECTION OF THE NOMINEES SPECIFIED BELOW.

The following is information with respect to the nominees for election as directors at the Annual Meeting that each nominee for director has given us about his age, all positions he holds, his principal occupation and his business experience for at least the past five years. In addition to the information presented below regarding each nominee’s specific experience, qualifications, attributes and skills that led our Board to the conclusion that he should serve as a director, we also believe that all of our directors have a reputation for integrity, honesty and adherence to high ethical standards. They each have demonstrated business acumen and an ability to exercise sound judgment, as well as a commitment to service to the Company and our Board.

# THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR”
THE FOUR NOMINEES FOR ELECTION TO THE BOARD OF DIRECTORS
DESCRIBED ABOVE

# BOARD AND COMMITTEE INFORMATION

## Board Meetings

A total of 11 meetings of the Board were held during the fiscal year ended December 31, 2017 (“Fiscal 2017”). During Fiscal 2017, no director attended fewer than 75 percent of the aggregate of (1) the Board meetings that were held, and (2) the meetings held by the committees of the Board on which he served.

## Committees of the Board of Directors

The Board has established a Compensation Committee, which is responsible for, among other things, assisting the Board in overseeing our executive compensation strategy and reviewing and approving the compensation of our executive officers and for the administration of the Company’s employee benefit plans. The Compensation Committee is also responsible for reviewing and approving the compensation of the Company’s directors. The executive officers do not determine executive or director compensation, but provide information and recommendations to the Compensation Committee upon its request. The members of the Compensation Committee are Messrs. Abbatecola, Monetta, Morch and Parrillo. The Compensation Committee held 4 meetings during Fiscal 2017. A copy of the Compensation Committee charter is available on the Company’s website at www.hudsontech.com.

The Board also has an Audit Committee which supervises the audit and financial procedures of the Company and is responsible for the selection of the Company’s independent registered public accountants. The members of the Audit Committee are Messrs. Abbatecola, Monetta, Morch, and Parrillo. The Board has determined that each member of the Audit Committee is an “independent director” within the meaning of the applicable NASDAQ Listing Rules and applicable Securities and Exchange Commission (“SEC”) rules under the Securities Exchange Act of 1934 (the “Exchange Act”). The Audit Committee does not have a member that qualifies as a “financial expert” under the federal securities laws. The members of the Audit Committee have each been active in the business community and have broad and diverse backgrounds, and financial experience. Two of the current members have served on the Company’s Audit Committee and have overseen the financial review by the Company’s independent auditors for more than 14 years. The Company believes that the current members of the Audit Committee are able to fully and faithfully perform the functions of the Audit Committee and that the Company does not need to install a “financial expert” on the Audit Committee. The Audit Committee held 6 meetings during Fiscal 2017. A copy of the Audit Committee charter is available on the Company’s website at www.hudsontech.com.

The Board also has an Executive Committee which is authorized to exercise the powers of the Board in the general supervision and control of the business affairs of the Company during the intervals between meetings of the Board. The members of the Executive Committee are Messrs. Abbatecola, Morch, Prouty and Zugibe.

The Board also has an Occupational, Safety and Environmental Protection Committee, which is responsible for satisfying the Board that the Company’s Environmental, Health and Safety policies, plans and procedures are adequate. The members of the Occupational, Safety and Environmental Protection Committee are Messrs. Monetta and Zugibe.

5

The Board has a Nominating Committee whose members consist of Messrs. Abbatecola, Monetta and Zugibe, and which was responsible for recommending to the independent directors the nominees for election to the Board at the annual meeting of the shareholders. In accordance with applicable NASDAQ Listing Rules, the nominees for director at the Annual Meeting named above were selected as nominees to the Board by vote of a majority of the independent directors. When reviewing candidates to our Board, the Nominating Committee and the independent members of the Board consider the evolving needs of the Board and seek candidates that fill any current or anticipated future needs. The Nominating Committee and the independent Board members also believe that all directors should possess the attributes described below in the last paragraph under the caption “Consideration of Director Nominees Recommended by Shareholders.” While neither the Nominating Committee nor the Board has a formal policy with respect to diversity, the Nominating Committee and the Board believe that it is important that the Board members represent diverse viewpoints. In considering candidates for the Board, the Nominating Committee and the independent members of the Board consider the entirety of each candidate’s credentials in the context of these standards. With respect to the nomination of continuing directors for re-election, the individual’s contributions to the Board are also considered.

Shareholder nominations for directors of the Company will be considered by the independent directors subject to the shareholder complying with the procedures described below. The Nominating Committee held one meeting during Fiscal 2017. The Nominating Committee does not have a charter.

## Board Leadership Structure

The Board believes our current leadership structure, where our Chief Executive Officer also serves as our Chairman of the Board, provides us with the most effective leadership model by enhancing the Chairman and Chief Executive Officer’s ability to provide insight and direction of business strategies and plans to both the Board and our management. The Board believes that a single person, acting in the capacities of Chairman and Chief Executive Officer, provides us with unified leadership and focus and that our business strategies are best served if the Chairman is also a member of our management team. We do not have a lead independent director; however, our Audit Committee and our Compensation Committee are comprised solely of independent directors and our Nominating Committee is comprised of a majority of independent directors. We believe the composition of these three Board committees, the fact that our independent directors determine Board nominees and the compensation of our executive officers, as well as the practice of our independent directors to meet in executive session without our Chief Executive Officer and the other members of our management present, help ensure that our Board maintains a level of independent oversight of management that is appropriate for our Company.

## Risk Management

The Board has an active role, as a whole and also at the committee level, in overseeing management of the Company’s risks. The Board regularly reviews information regarding the Company’s credit, liquidity and operations, as well as the risks associated with each. The Company’s Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. The Audit Committee oversees management of financial risks and potential conflicts of interest with related parties. The Nominating Committee manages risks associated with the independence of the Board. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports, or otherwise, about such risks.

## Compensation Committee Interlocks and Insider Participation

During Fiscal 2017, Messrs. Abbatecola, Monetta, Morch and Parrillo served as members of our Compensation Committee. No Member of our Compensation Committee is, or was during Fiscal 2017, an employee or an officer of Hudson or its subsidiaries.

## Audit Committee Report

In December 2017, the Audit Committee met with management to review and discuss the audit and the procedures and timing of the audit. In February 2018, the Audit Committee met with management to review and discuss the audited financial statements. The Audit Committee also discussed with the Company’s independent registered public accounting firm, BDO USA, LLP the matters required to be discussed by the statement on Auditing Standards No. 1301 “Communications With Audit Committees” as adopted by the Public Company Accounting Oversight Board. The Audit Committee has received the written disclosures and confirming letter from BDO USA, LLP required by the applicable requirements of the Public Company Accounting Oversight Board regarding its independence and has discussed with BDO USA, LLP its independence from the Company. Based upon the review and discussions referred to above, the Audit Committee ratified its prior recommendation to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

The Audit Committee —

Vincent Abbatecola, Dominic Monetta, Otto Morch, and Richard Parrillo.

## Code of Conduct and Ethics

The Company has adopted a written code of conduct and ethics that applies to all directors, and employees, including the Company’s principal executive officer, principal financial officer, principal accounting officer or controller and any persons performing similar functions. The Company will provide a copy of its code of conduct and ethics to any person without charge upon written request addressed to Hudson Technologies, Inc., PO Box 1541, One Blue Hill Plaza, Pearl River, New York 10965, Attention: Stephen P.

The Board generally requires that director candidates be qualified individuals who, if added to the Board, would provide the mix of director characteristics, experience, perspectives and skills appropriate for Hudson. Criteria to be considered for selection of candidates will include, but not be limited to: (i) business and financial acumen, as determined by the Board in its discretion, (ii) qualities reflecting a proven record of accomplishment and ability to work with others, (iii) knowledge of Hudson’s industry, (iv) relevant experience and knowledge of corporate governance practices, and (v) expertise in an area relevant to Hudson. Such persons should not have commitments that would materially conflict with the time commitments of a Director of Hudson.

# DEADLINE AND PROCEDURES FOR SUBMITTING BOARD NOMINATIONS

A shareholder wishing to nominate a candidate for election to the Board at the Annual Meeting of Shareholders to be held in 2019, which we currently anticipate will be held in or about June 2019, is required to give written notice containing the required information specified above and otherwise in accordance with our By-Laws, addressed to the Independent Directors of the Board, c/o Secretary of the Company, Hudson Technologies, Inc., PO Box 1541, One Blue Hill Plaza, Pearl River, NY 10965, of his or her intention to make such a nomination. The notice of nomination and other required information must be received by the Company’s Secretary no earlier than February 8, 2019 and no later than March 9, 2019. In the event that the Annual Meeting of Shareholders to be held in 2019 is held either before May 7, 2019 or after August 6, 2019, then the notice of nomination and other required information must be received by the Company’s Secretary no later than 90 days prior to the date of such meeting or, within 10 days following the first public announcement of the date of such annual meeting if such public announcement is made less than 100 days prior to the date of such meeting.

In addition, to be timely, a shareholder’s notice must be updated and supplemented, if necessary, so that the information provided or required to be provided in such notice will be true and correct as of the record date for the 2019 Annual Meeting and as of the date that is 10 business days prior to such meeting or any adjournment or postponement thereof, and such update and supplement must be delivered to, or mailed and received by, the Chairman of the Board of Directors at the principal executive offices of the Company not later than 5 business days after the record date for the meeting (in the case of the update and supplement required to be made as of the record date), and not later than 8 business days prior to the date for the meeting, or if the meeting is adjourned or postponed, on the first practicable date after any adjournment or postponement thereof (in the case of the update and supplement required to be made as of 10 business days prior to the meeting or any adjournment or postponement thereof).

## Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires the Company’s officers and directors and persons who own more than 10% of a registered class of the Company’s equity securities (collectively, the “Reporting Persons”) to file reports of ownership and changes in ownership with the SEC. Reporting Persons are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

Based solely on Hudson’s review of copies of such forms received by Hudson, and on representations made to us, we believe that during the year ended December 31, 2017, all filing requirements applicable to all officers, directors and greater than 10% beneficial shareholders were timely complied with.

# EXECUTIVE COMPENSATION

## Compensation Discussion and Analysis

## Overview of Compensation Program and Philosophy

Our compensation program is intended to:

| • | Attract, motivate, retain and reward employees of outstanding ability;

| • | Link changes in employee compensation to individual and corporate performance;

| • | Align employees’ interests with those of the Company’s shareholders.

The ultimate objective of our compensation program is to increase shareholder value. We seek to achieve these objectives with a total compensation approach which takes into account a competitive base salary, bonus pay based on the annual performance of the Company and individual goals and equity incentive awards.

The Board’s Compensation Committee, which is comprised solely of independent directors and is responsible for making decisions regarding the amount and form of compensation paid to the Company’s executive officers, has carefully considered the results of prior say-on-pay shareholder votes. Based upon the vote results at the most recent annual shareholders meeting, shareholders appear to be supportive of the Compensation Committee’s approach to the executive compensation program. The Compensation Committee did not retain any outside compensation consultants during Fiscal 2017.

## Base Salaries

Base salaries paid to executives are intended to attract and retain highly talented individuals. In setting base salaries, individual experience, individual performance, the Company’s performance and job responsibilities during the year are considered. Executive salaries are reconciled by Human Resources and evaluated by the Compensation Committee on a bi-annual basis against local companies of similar size and nature. No changes were made to the base salaries of any of the Company’s executive officers during the fiscal year ended December 31, 2017.

## Annual Bonus Plan Compensation

In December 2015, the Company established an annual bonus program for the payment of cash and/or equity awards to some or all of the executive officers based upon the Company’s annual earnings and potentially other financial and personal metrics. The amount of the aggregate pool to be established each year will be determined by the Compensation Committee on or about the end of each fiscal year, based upon the Company achieving earnings in excess of a pre-determined level for each fiscal year (the “Benchmark”). In the event the Company’s earnings exceed the Benchmark for the applicable fiscal year, some or all of the executive officers may receive bonuses in the form of cash, stock options, stock or some combination thereof. The Compensation Committee will determine the amount, if any, of the awards to be received by the Chief Executive Officer (“CEO”) and the President/Chief Operating Officer (“COO”) and whether the awards will be made in cash, stock options or stock, or some combination thereof, which determination will be made, based upon the overall financial results of the Company during the applicable fiscal year as well as on the personal performance of the CEO and COO during the applicable fiscal year. The CEO and the COO will determine the amount, if any, of the awards to be received to all other executive officers, and whether the awards will be made in cash, stock options or stock, or some combination thereof, which determination will be made based upon the overall financial results of the Company during the applicable fiscal year as well as on the personal performance of each of the executive officers during the applicable fiscal year.

For fiscal year 2017, the Compensation Committee determined that the 2017 Benchmarks determined by the Compensation Committee had been achieved and established a total bonus pool not to exceed $450,000 for the award of bonuses to the Executive Officers in accordance with the Company’s annual bonus program, which bonuses were paid in the form of stock options that were issued to the Executive Officers in the fourth quarter of 2017. The Compensation Committee also determined to issue bonuses to the executive officers for the successful completion of the acquisition of Airgas-Refrigerants, Inc. which was completed on October 10, 2017 (the “Acquisition”) and established a bonus pool of $1,374,610 for the award of bonuses of which a

10

minimum of $924,610 was to be paid in the form of stock options. Mr. Zugibe received a cash bonus of $130,000 and stock option bonuses of $532,800 based upon the Company achieving the earnings benchmark and for the successful completion of the Acquisition. Mr. Coleman received a cash bonus of $100,000 and stock option bonuses of $346,300 based upon the Company achieving the earnings benchmark and for the successful completion of the Acquisition. Mr. Krishnamurti received a cash bonus of $70,000 and stock option bonuses of $165,000 based upon the Company achieving the earnings benchmark and for the successful completion of the Acquisition. Mr. Harkins a received a cash bonus of $90,000 and stock option bonuses of $174,510 based upon the Company achieving the earnings benchmark and for the successful completion of the Acquisition. Mr. Mandracchia received a cash bonus of $60,000 and stock option bonuses of $156,000 based upon the Company achieving the earnings benchmark and for the successful completion of the Acquisition.

## Equity Incentive Awards

Company executives are eligible to receive restricted stock and stock options (which give them the right to purchase shares of common stock at a specified price in the future). These grants will vest based upon the passage of time, the achievement of performance metrics, or both. We believe that the use of restricted stock and stock options as the basis for long-term incentive compensation meets our defined compensation strategy and business needs by achieving increased value for stockholders and retaining key employees.

Stock option awards are intended to attract and retain highly talented executives, to provide an opportunity for significant compensation when overall Company performance is reflected in the stock price and to help align executives’ and shareholders’ interests. Stock options are typically granted at the time of hire to key new employees and annually to a broad group of existing key employees, including executive officers. We have adopted a number of equity compensation plans governing the grant of such stock options. All of our equity compensation plans have been approved by our shareholders.

Annual option grants to executive officers are made at the discretion of the Board or the Compensation Committee and may be in the form of incentive stock options (“ISOs”) up to the fullest extent permitted under tax laws, with the balance granted in the form of nonqualified stock options. The option grants are subject to the terms of the relevant plan. ISOs have potential income tax advantage for executives if the executive disposes of the acquired shares after satisfying certain holding periods. Tax laws provide that the aggregate grant at date of grant for market value of ISOs that become exercisable for any employee in any year may not exceed $100,000.

Our current practice for options issued to all employees and to non-employee directors is to issue options that vest immediately upon issuance, carry of term of three years and establish a “barrier” for the market price, of the Company’s common stock, which results in the cancellation of the options if the closing stock price of the Company’s common stock is below the barrier price for five consecutive days.

The number of stock options granted in Fiscal 2017 to the named executive officers, and their estimated fair value, were as follows:

Named Executive Officer |  | Grant Date |  | Number of Options Granted |  | Estimated Fair Value of Awards at Grant Date
Kevin J. Zugibe |  |  | 12/19/2017 |  |  |  | 484,364 |  |  | $ | 532,800 |
Brian F. Coleman |  |  | 12/19/2017 |  |  |  | 314,818 |  |  | $ | 346,300 |
Nat Krishnamurti |  |  | 12/19/2017 |  |  |  | 150,000 |  |  | $ | 165,000 |
Charles F. Harkins |  |  | 12/19/2017 |  |  |  | 158,645 |  |  | $ | 174,510 |
Stephen P. Mandracchia |  |  | 12/19/2017 |  |  |  | 141,818 |  |  | $ | 156,000 |

The stock options awarded to Messrs. Zugibe, Coleman, Krishnamurti, Harkins and Mandracchia in December 2017 had an exercise price of $5.70 (which was equal to the closing market price per share of our stock on the date of the grant).

All stock options in the above table were granted pursuant to the Annual Bonus Plan described above and provide for 100% vesting on the date of issuance, have a barrier price of $4.50 with a stated expiration date of three years after grant.

11

We did not make grants of restricted stock to our named executive officers during Fiscal 2017. As part of his initial compensation package, Mr. Krishnamurti is to receive a total of 20,000 shares of unrestricted common stock of the Company, of which 14,000 shares were issued at the time of his hiring, an additional 3,000 shares were issued to him in September 2017 on the first anniversary of his hiring, and an additional 3,000 shares are to be issued to him on second anniversary of his hiring.

## Other Annual Compensation and Benefits

Although direct compensation, in the form of salary, non-equity incentive awards and long-term equity incentive awards provide most of the compensation to each Executive Officer, we also provide for the following items of additional compensation:

| • | Retirement savings are provided by a 401(k) plan, in the same manner to all U.S. employees. This plan includes an employer matching contribution of 20% of an employee’s annual contribution up to a maximum of $600 which is intended to encourage employees (including the chief executive officer) to save for retirement.

| • | Health, life and disability benefits are offered to our executive officers in the same manner to all of our U.S. employees. We provided additional long term disability and long term care policies for each of our executive officers.

## Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K promulgated under the Securities and Exchange Act of 1934, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our CEO. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. There are a variety of different methodologies, assumptions, adjustments and estimates that companies may apply in compliance with Item 402(u) of Regulation S-K; as such, the information provided should not be used as a basis for comparison between different companies.

For 2017, the annual total compensation of the median employee of our company was $46,668.64, and the annual total compensation of our CEO, as reported in the Summary Compensation Table above, was $1,201,000. Based on this information, the ratio of the annual total compensation of our CEO, Mr. Zugibe, to the median of the annual total compensation of all employees was 26 to 1.

In order to identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our CEO, we took the following steps:

We determined that, as of December 31, 2017, our employee population consisted of approximately 270 individuals. This population consisted of our full-time, part-time, temporary and seasonal employees. December 31, 2017 was selected as the date upon which we would identify the “median employee,” because it allowed us to identify our median employee in a reasonably efficient and economical manner.

To identify the median employee, we compared 2017 W-2 taxable Medicare wages (Box 5) as reported to the Internal Revenue Service. This compensation measure was consistently applied to all employees included in the calculation.

Once the median employee was identified, we calculated annual total compensation for such employee using the same methodology we use for our NEOs as reported in the 2017 Summary Compensation Table above. With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of the table.

## Employment, Termination, Change of Control and other Agreements

## Stock Option Plans

#### 2004 Stock Incentive Plan

We have adopted the 2004 Stock Incentive Plan (the “2004 Plan”), pursuant to which 2,500,000 shares of our common stock were reserved for issuance upon the exercise of options, designated as either (i) ISOs, under the Code or (ii) non-qualified options, or for issuance upon the granting of restricted stock, deferred stock or other stock-based awards. ISOs could be granted under the 2004 Plan to employees and officers of Hudson. Non-qualified options, restricted stock, deferred stock or other stock-based awards could be granted to consultants, directors (whether or not they are employees), employees or officers of Hudson. Stock appreciation rights could also be issued in tandem with stock options. The ability to grant options or other awards under the 2004 Plan expired on September 10, 2014.

As of December 31, 2017, we had options outstanding to purchase 207,000 shares of common stock under the 2004 Plan.

#### 2008 Stock Incentive Plan

We have adopted the 2008 Stock Incentive Plan (the “2008 Plan”), pursuant to which 3,000,000 shares of our common stock are currently reserved for issuance upon the exercise of options, designated as either (i) ISOs, under the Code or (ii) non-qualified options, or for issuance upon the granting of restricted stock, deferred stock or other stock-based awards. ISOs may be granted under the 2008 Plan to employees and officers of Hudson. Non-qualified options, restricted stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of Hudson. Stock appreciation rights may also be issued in tandem with stock options.

The 2008 Plan is intended to qualify under Rule 16b-3 under the Exchange Act and is administered by our Compensation Committee of the Board of Directors. The Committee, within the limitations of the 2008 Plan, determines the persons to whom options will be granted, the number of shares to be covered by each option, whether the options granted are intended to be ISOs, the duration and rate of exercise of each option, the exercise price per share and the manner of exercise and the time, manner and form of payment upon exercise of an option. In the case of restricted stock, deferred stock or other stock-based awards, the Committee, within the limitations of the 2008 Plan, determines the persons to whom awards will be granted, the number of shares of stock subject to the award, and the restrictions on issuance and transfer of such shares. Unless the 2008 Plan is sooner terminated, the ability to grant options or other awards under the 2008 Plan will expire on June 19, 2018.

ISOs granted under the 2008 Plan may not be granted at a price less than the fair market value of our common stock on the date of grant (or 110% of fair market value in the case of ISOs granted to a 10% shareholder). In the case of ISOs, the aggregate fair market value of shares for which ISOs granted to any employee are exercisable for the first time by such employee during any calendar year (under all of our stock option plans) may not exceed $100,000. Non-qualified options granted under the 2008 Plan may not be granted at a price less than the fair market value of our common stock. Options granted under the 2008 Plan will expire not more than ten years from the date of grant (five years in the case of ISOs granted to a 10% shareholder). Except as otherwise provided by the Committee with respect to non-qualified options, all options, restricted stock, deferred stock or other stock-based awards granted under the 2008 Plan are not

17

transferable during a grantee’s lifetime but are transferable at death by will or by the laws of descent and distribution. In general, upon termination of employment of a grantee, all options, restricted stock, deferred stock or other stock-based awards granted to such person which are not exercisable on the date of such termination immediately terminate, and any options that are exercisable terminate 90 days following termination of employment.

As of December 31, 2017, we had options outstanding to purchase 2,115,159 shares of common stock and 24,411 shares are reserved for future issuances under the 2008 Plan.

#### 2014 Stock Incentive Plan

We have adopted the 2014 Stock Incentive Plan (the “2014 Plan”), pursuant to which 3,000,000 shares of our common stock are currently reserved for issuance upon the exercise of options, designated as either (i) ISOs, under the Code or (ii) non-qualified options, or for issuance upon the granting of restricted stock, deferred stock or other stock-based awards. ISOs may be granted under the 2014 Plan to employees and officers of Hudson. Non-qualified options, restricted stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of Hudson. Stock appreciation rights may also be issued in tandem with stock options.

The 2014 Plan is intended to qualify under Rule 16b-3 under the Exchange Act and is administered by our Compensation Committee of the Board of Directors. The Committee, within the limitations of the 2014 Plan, determines the persons to whom options will be granted, the number of shares to be covered by each option, whether the options granted are intended to be ISOs, the duration and rate of exercise of each option, the exercise price per share and the manner of exercise and the time, manner and form of payment upon exercise of an option. In the case of restricted stock, deferred stock or other stock-based awards, the Committee, within the limitations of the 2014 Plan, determines the persons to whom awards will be granted, the number of shares of stock subject to the award, and the restrictions on issuance and transfer of such shares. Unless the 2014 Plan is sooner terminated, the ability to grant options or other awards under the 2014 Plan will expire on September 17, 2024.

ISOs granted under the 2014 Plan may not be granted at a price less than the fair market value of our common stock on the date of grant (or 110% of fair market value in the case of ISOs granted to a 10% shareholder). In the case of ISOs, the aggregate fair market value of shares for which ISOs granted to any employee are exercisable for the first time by such employee during any calendar year (under all of our stock option plans) may not exceed $100,000. Non-qualified options granted under the 2014 Plan may not be granted at a price less than the fair market value of our common stock. Options granted under the 2014 Plan will expire not more than ten years from the date of grant (five years in the case of ISOs granted to a 10% shareholder). Except as otherwise provided by the Committee with respect to non-qualified options, all options, restricted stock, deferred stock or other stock-based awards granted under the 2014 Plan are not transferable during a grantee’s lifetime but are transferable at death by will or by the laws of descent and distribution. In general, upon termination of employment of a grantee, all options, restricted stock, deferred stock or other stock-based awards granted to such person which are not exercisable on the date of such termination immediately terminate, and any options that are exercisable terminate 90 days following termination of employment.

As of December 31, 2017, we had options outstanding to purchase 765,281 shares of common stock under the 2014 Plan and 2,234,719 shares are reserved for future issuances under the 2014 Plan.

# CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

During 2017, Mr. Prouty provided consulting services to the Company and received compensation of $48,000 from the Company for those services. The Company may from time to time utilize Mr. Prouty for additional consulting services and on such occasions will provide compensation to Mr. Prouty for those services.

#### Review, approval or ratification of transactions with related persons

Each year, all of our directors and officers are asked to disclose the existence of family relationships and other related transactions in Director and Officer Questionnaires. Our Audit Committee is responsible for reviewing and approving or ratifying related-person transactions. A related person is any executive officer, director or more than 5% stockholder, or any immediate family member of the foregoing persons, or entity owned or controlled by such person. In addition, pursuant to our Code of Business Conduct and Ethics, all of our employees and directors are required to bring any conflict of interest to the attention of one of the Company’s executive officers or directors. In determining whether to approve or ratify a related party transaction, the Audit Committee will consider, among other factors it deems appropriate, whether the related party transaction is on terms no less favorable to us than terms generally available to us from an unaffiliated third-party under the same or similar circumstances, and the extent of the related party’s interest in the transaction. Any transaction which is deemed to be a related party transaction requires the approval, initially by a majority of the non-interested Audit Committee members and finally by a majority of the non-interested Board members. There are no other written procedures governing any review of related person transactions.

# PROPOSAL 2
APPROVAL OF 2018 STOCK INCENTIVE PLAN

Subject to the approval of the Company’s shareholders, the Board approved the Hudson Technologies, Inc. 2018 Stock Incentive Plan (the “Stock Incentive Plan”) on April 10, 2018.

## General Description of the Stock Incentive Plan

The Stock Incentive Plan may be administered by the Compensation Committee or another committee appointed by the Board from among its members. In the absence of such committee, the Board shall administer the Plan. The Compensation Committee (i) may delegate to one or more of its members, or to one or more agents, such administrative duties as it may deem advisable, and (ii) may delegate any of its responsibilities to a subcommittee comprised of one or more members of the Compensation Committee or to the CEO, including, but not limited to, the authority to make grants of awards of stock rights or options to any officer or employee of the Company, other than officers subject to Section 16 of the Securities Exchange Act of 1934, under the Stock Incentive Plan, as the Compensation Committee deems appropriate. Presently, it is anticipated that the Stock Incentive Plan, except as otherwise required in the Stock Incentive Plan, will be administered by the Compensation Committee. As used throughout this section, the term “Administrator” refers to the Board, the Compensation Committee, or other Board Committee in its role as administrator of the Stock Incentive Plan, if applicable.

Under the Stock Incentive Plan, the Administrator is authorized to grant awards to non-employee directors, executive officers and other employees of, and consultants and advisors to, the Company or any of its subsidiaries and to determine the number and types of such awards and the terms, conditions, vesting and other limitations applicable to each such award. In addition, the Administrator has the power to interpret the Stock Incentive Plan and to adopt such rules and regulations as it considers necessary or appropriate for purposes of administering the Stock Incentive Plan.

The following types of awards or any combination of them may be granted under the Stock Incentive Plan: (i) incentive stock options, (ii) non-qualified stock options, (iii) stock grants, and (iv) performance awards. The maximum number of shares of Common Stock with respect to which awards may be granted to any individual participant under the Stock Incentive Plan during each of the Company’s fiscal years will not exceed 750,000 shares, subject to certain adjustments.

The aggregate number of shares of Common Stock reserved for awards under the Stock Incentive Plan is 4,000,000 shares, subject to adjustments for stock splits, recapitalizations and other specified events. Such shares may be treasury shares or authorized but unissued shares. If any outstanding award is cancelled, forfeited, or surrendered to the Company, shares of Common Stock allocable to such award may again be available for awards under the Stock Incentive Plan. Incentive stock options may be granted only to participants who are executive officers or to other employees of the Company or any of its subsidiaries on the date of the grant, and non-qualified stock options may be granted to any participant in the Stock Incentive Plan. No stock option granted under the Stock Incentive Plan will be exercisable later than ten years after the date it is granted.

Set forth below is a summary of the principal features of the Stock Incentive Plan. The summary of the Stock Incentive Plan is not intended to be complete and is qualified in its entirety by reference to the full text of the Stock Incentive Plan attached to this proxy statement as Appendix A.

The purpose of the Stock Incentive Plan is to provide incentives to attract, retain, motivate and reward highly competent persons as non-employee directors, executive officers and other employees of, or consultants or advisors to, Hudson or any of its subsidiary corporations, limited liability companies or other forms of business entities now existing or hereafter formed or acquired (“Subsidiaries”) by providing them with opportunities to acquire shares of Common Stock or to receive other awards under the Stock Incentive Plan, as applicable. Furthermore, the Stock Incentive Plan is intended to assist in further aligning the interests of participants in the Stock Incentive Plan with those of the shareholders of Hudson.

23

### Consideration to be Received by Hudson for the Granting of Awards

The Board believes that Hudson and its Subsidiaries will significantly benefit from having Hudson’s non-employee directors, executive officers, other employees, consultants or advisors, receive options to purchase Common Stock and other awards under the Stock Incentive Plan, as applicable. Providing an opportunity to the foregoing participants in the Stock Incentive Plan to acquire Common Stock or benefit from the appreciation of Common Stock is valuable in attracting and retaining highly qualified outside directors, employees, consultants and advisors and in providing additional motivation to such persons to use their best efforts on behalf of Hudson and its shareholders.

### Awards

As a single award, or in any combination, the following types of awards may be granted under the Stock Incentive Plan: (i) “Stock Options” (both “Incentive Stock Options” and “Non-Qualified Stock Options”) to acquire shares of common stock; (ii) “Stock Grants” which entitle the grantee to acquire shares of Common Stock which may be subject to certain restrictions such as restrictions on transferability; and (iii) “Performance Awards,” which entitle the grantee to receive, without payment, shares of Common Stock or the value of such shares following the attainment of performance goals. Awards are evidenced by award agreements in such forms as the Administrator approves from time to time. Each award is subject to such terms and conditions consistent with the Stock Incentive Plan, as determined by the Administrator and as set forth in the award agreement. The Administrator shall have the authority to retract any award granted under the Stock Incentive Plan in case of a material restatement of the financial statements of Hudson or if it is otherwise determined by the Administrator that the previously granted award was not earned by the participant.

### Administration of the Stock Incentive Plan

The Stock Incentive Plan may be administered by the Administrator, which may be the Board or the Compensation Committee or, if the Board so determines, by other applicable Board Committee. Under the Stock Incentive Plan, the Administrator is authorized to grant awards to non-employee directors, executive officers, and other employees of and consultants and advisors to, Hudson or any of its Subsidiaries and to determine the number and types of such awards and the terms, conditions, vesting and other limitations applicable to each such award. In addition, the Administrator has the power to interpret the Stock Incentive Plan and to adopt such rules and regulations as it considers necessary or appropriate for purposes of administering the Stock Incentive Plan. The Compensation Committee (i) may delegate to one or more of its members, or to one or more agents, such administrative duties as it may deem advisable, and (ii) may delegate any of its responsibilities to a subcommittee comprised of one or more members of the Compensation Committee or to the CEO, including, but not limited to, the authority to make grants of awards of stock rights or options to any officer or employee of the Company, other than officers subject to Section 16 of the Securities Exchange Act of 1934, under the Stock Incentive Plan, as the Compensation Committee deems appropriate.

The Board has the authority to establish stock grant levels and stock ownership guidelines for non-employee directors.

### Eligibility and Participation

All non-employee directors, executive officers and other employees of, and consultants and advisors to, Hudson or any of its Subsidiaries, who are significantly responsible for the success and future growth and profitability of Hudson, as determined by the Administrator, are eligible to be participants in the Stock Incentive Plan. As of the date of this proxy statement, seven directors, three non-director executive officers and approximately 250 employees were eligible to be participants under the Stock Incentive Plan. We are presently unable to determine the number of consultants or advisors who may be eligible to receive awards under the Stock Incentive Plan. The number of persons covered by the Stock Incentive Plan may increase if we employ additional employees, elect additional directors or retain additional consultants and advisors. A participant’s right, if any, to continue to serve Hudson as a director, executive officer or other employee, or otherwise will not be enlarged or otherwise affected by his or her designation as a participant under the Stock Incentive Plan. Participants may receive one or more awards under the Stock Incentive Plan. To date, no awards have been granted under the Stock Incentive Plan.

24

### Shares Subject to Awards

The aggregate number of shares of Common Stock that are currently reserved for awards, including shares underlying stock options, that may be granted under the Stock Incentive Plan is 4,000,000 shares, subject to adjustments for stock splits, recapitalizations and other specified events. The maximum number of shares of Common Stock with respect to which awards may be granted or measured to any individual participant under the Stock Incentive Plan during any fiscal year of Hudson may not exceed 750,000 shares, subject to certain adjustments. Such shares may be treasury shares or authorized but unissued shares. If any outstanding award is canceled, forfeited, or surrendered to Hudson, the underlying shares of Common Stock allocable to such award may again be available for awards under the Stock Incentive Plan.

### Stock Options

Stock Options granted under the Stock Incentive Plan may be either Incentive Stock Options (within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”)) or Non-Qualified Stock Options that do not qualify as Incentive Stock Options; provided, however, that no Incentive Stock Option may be issued in tandem with a Non-Qualified Stock Option. See “U.S. Federal Income Tax Consequences.”

The Administrator determines the exercise price at which shares underlying a Stock Option may be purchased, whether an Incentive Stock Option or a Non-Qualified Stock Option. However, the exercise price of a Stock Option may not be less than the fair market value of the shares of Common Stock on the date the Stock Option is granted. No Stock Option will be exercisable later than ten years after the date it is granted. Stock Options granted under the Stock Incentive Plan are exercisable at such times as specified in the Stock Incentive Plan and the award agreement relating to the Stock Option. A participant in the Stock Incentive Plan must pay the option exercise price in cash, unless the Administrator prescribes another method consistent with applicable law and the Plan.

Incentive Stock Options may be granted only to executive officers and other employees of Hudson or any of its Subsidiaries on the date of grant. The aggregate market value (determined as of the date of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by a participant during any calendar year may not exceed $100,000. Furthermore, Incentive Stock Options may not be granted to any participant who, at the time of grant, owns stock possessing more than 10% of the total combined voting power of all outstanding classes of stock of Hudson or any of its Subsidiaries, unless the exercise price is fixed at not less than 110% of the fair market value of the Common Stock on the date of grant, and such an Incentive Stock Option cannot be exercised more than five years after the date of grant.

### Stock Grants

Stock Grants may be granted to non-employee directors, executive officers and other employees of, or consultants or advisors to, Hudson or any of its Subsidiaries. A Stock Grant may include restrictions on the sale or other disposition of the shares covered by the award, and Hudson may have the right to reacquire such shares for no consideration upon termination of the participant’s employment within specified periods. The award agreement will specify whether the participant will have, with respect to the shares of Common Stock subject to a Stock Grant, all of the rights of a holder of shares of Common Stock, including the right to receive dividends, if any, and to vote the shares.

### Performance Awards

Performance Awards may be granted to executive officers and other employees of Hudson or any of its Subsidiaries. The Administrator will set performance targets at its discretion which, depending on the extent to which they are met, will determine the number and/or value of Performance Awards that will be paid out to the participants and may attach to such Performance Awards one or more restrictions. Performance targets may be based upon Company-wide, divisional and/or individual performance.

Payment of earned Performance Awards may be made in shares of Common Stock or in cash and will be made in accordance with the terms and conditions prescribed or authorized by the Administrator. The participant may elect to defer, or the Administrator may require or permit the deferral of, the receipt of Performance Awards upon such terms as the Administrator deems appropriate.

25

### Effect of Change in Control

The Stock Incentive Plan provides for the acceleration of certain benefits in the event of a “Change in Control” of Hudson. The meaning of a “Change in Control” is either defined in the participant’s employment agreement or change-in-control agreement, if one exists, or by the Stock Incentive Plan. The Stock Incentive Plan definition includes, among other things, such events as the sale of all or substantially all of the assets of Hudson, any person becoming the beneficial owner of more than 50% of Hudson voting stock, and a merger of Hudson where Hudson stockholders own less than 51% of the voting stock of the surviving entity.

All unvested awards granted under the Stock Incentive Plan will become fully vested immediately upon the occurrence of the Change in Control and such vested awards will be paid out or settled, as applicable, within 60 days upon the occurrence of the Change in Control, subject to requirements of applicable laws and regulations. The Administrator may determine that upon the occurrence of a Change in Control, each Stock Option outstanding will terminate and the holder will receive, within 60 days upon the occurrence of the Change in Control, an amount equal to the excess of the fair market value of the shares underlying the award immediately prior to the occurrence of such Change in Control over the exercise price per share of such award. This cashout amount is payable in cash, in one or more kinds of property (including the property, if any, payable in the transaction) or in a combination thereof, as the Administrator, in its discretion, shall determine.

### Adjustments to Awards Due to Changes in Hudson’s Capital Structure

In the event of any change in the shares of Common Stock by reason of a merger, consolidation, reorganization, recapitalization, stock split, reverse stock split, stock dividend, split up, spinoff, combination of shares, exchange of shares, dividend in kind, or other similar change in the corporate structure or distribution (other than normal cash dividends) to stockholders, each outstanding Stock Option will be adjusted. The adjustments will make each award exercisable thereafter for the securities, cash and/or other property as would have been received in respect of the Common Stock subject to such award had the Stock Option been exercised in full immediately prior to the change or distribution. Furthermore, in the event of any such change or distribution, in order to prevent dilution or enlargement of participants’ rights under the Stock Incentive Plan, the Administrator shall make equitable adjustments to, among other things, the number and kind of shares subject to outstanding awards and exercise price of outstanding awards.

### Termination of Employment

Except as otherwise expressly provided, if a participant’s employment is terminated due to death or disability, then the participant’s unvested Stock Grants and unexercisable Stock Options shall become vested or exercisable, as applicable, immediately as of the date of the termination of the participant’s employment. All Stock Options that were or became exercisable as of the date of the participant’s death or such termination of employment, will remain exercisable until the earlier of (i) the end of the one-year period following the date of the participant’s death or following the date of the termination of his or her employment, as the case may be, or (ii) the date the Stock Option would otherwise expire. All unearned or unvested Performance Awards held by the participant (with a minimum of one year into the performance period) on the date of the participant’s death or the date of such termination of his or her employment, as the case may be, will immediately become earned or vested as of such date and will be paid out or settled based on the participant’s performance immediately prior to the date of the participant’s death or the date of such termination of his or her employment on a pro-rated basis.

Except as otherwise expressly provided, a participant whose employment is voluntarily terminated by the participant, or whose employment is terminated for cause, as defined in the Stock Incentive Plan, forfeits all awards, whether or not vested, exercisable or earned, granted to the participant.

Unless otherwise provided by the Administrator, a participant whose employment is terminated for any reason, other than for cause, death or disability, including, without limitation, retirement, forfeits all unvested, unexercisable and unearned awards granted to the participant. All exercisable Stock Options held by the participant on the date of the termination of his or her employment for any reason other than for voluntary termination, cause, death or disability will remain exercisable until the earlier of (i) the end of the 90-day period following the date of the termination of the participant’s employment, or (ii) the date the Stock Option

26

would otherwise expire. The Stock Incentive Plan’s provisions relating to termination of employment may be modified in the discretion of the Administrator.

### Transferability

Each award granted under the Stock Incentive Plan which is subject to restrictions on transferability and/or exercisability is not transferable otherwise than by will or the laws of descent and distribution, and/or is exercisable, during the participant’s lifetime, only by the participant. The Administrator may allow a Stock Option to be exercisable during a period after the death of the participant by the executor or administrator of the estate of the deceased participant or the person or persons to whom the deceased participant’s rights under the Stock Option will pass by will or the laws of descent and distribution. The Administrator also may permit an award (other than an Incentive Stock Option) to be transferred by a participant solely to members of the participant’s immediate family or trusts or family partnerships for the benefit of such persons, subject to any restriction included in the award agreement.

### Amendment of Awards

The terms and conditions applicable to any award may be amended or modified by mutual agreement between Hudson and the participant or any other persons as may then have an interest in the award. Also, by mutual agreement between Hudson and a participant under the Stock Incentive Plan or under any other present or future plan of Hudson, awards may be granted to a participant in substitution and exchange for, and in cancellation of, any awards previously granted to a participant under the Stock Incentive Plan or any other present or future plan of Hudson.

### Term and Amendment of the Stock Incentive Plan

If the Stock Incentive Plan is approved at the Annual Meeting it will terminate on June 7, 2028, unless terminated sooner by the Board or the Administrator. Subject to the provisions of the Stock Incentive Plan, the Board or the Administrator, if other than the Board, may amend the Stock Incentive Plan from time to time, and suspend or terminate the Stock Incentive Plan at any time. Without stockholder approval, no amendment may (i) increase the total number of shares which may be issued under the Stock Incentive Plan or the maximum number of shares with respect to which Stock Options and other awards that may be granted to any individual under the Stock Incentive Plan; (ii) modify the requirements as to eligibility for awards under the Stock Incentive Plan; (iii) disqualify any Incentive Stock Options granted under the Stock Incentive Plan; or (iv) effect the repricing of Stock Options.

## U.S. Federal Income Tax Consequences

The following information summarizes the material U.S. federal income tax consequences upon participants and the Company with respect to the grant and exercise of stock options under the Stock Incentive Plan. It does not purport to be complete, and does not discuss the tax consequences of a participant’s death or the provisions of the income tax laws of any municipality, state or foreign country in which the participant may reside. This summary is qualified in its entirety by reference to the applicable provisions of the Code and the regulations adopted under the Code, each as in effect on the date hereof.

Participants are encouraged to consult their own tax advisors regarding the municipal, state, U.S. federal and foreign income tax consequences in their particular circumstances and with respect to their particular awards. The provisions of the Code described in this section include current U.S. federal income tax law only and do not reflect any proposals to revise current tax law. The U.S. federal income tax consequences applicable to officers, directors, and other persons who are subject to potential liability under Section 16(b) of the Exchange Act may be different than the U.S. federal income tax consequences applicable to persons who are not subject to Section 16(b).

To ensure compliance with IRS Circular 230, stockholders are hereby notified that: (a) any discussion of federal tax issues contained or referred to herein is not intended or written to be used, and cannot be used by a stockholder, for the purpose of avoiding penalties that may be imposed on the stockholder under the Internal Revenue Code, (b) such discussion is written in connection with this proxy statement and the matters addressed herein, and (c) a stockholder should seek advice based on his, her or its particular circumstances from an independent tax advisor.

### Incentive Stock Options

Generally, under the Code, an optionee will not realize taxable income by reason of the grant or exercise of an Incentive Stock Option granted pursuant to the Stock Incentive Plan (see, however, discussion of alternative minimum tax below). If an optionee exercises an Incentive Stock Option and does not dispose of the shares until the later of: (i) two years from the date the option was granted and (ii) one year from the date of exercise, the entire gain, if any, realized upon disposition of such shares will be taxable to the optionee as long-term capital gain, and Hudson will not be entitled to any income tax deduction. If an optionee disposes of the shares within the period of two years from the date of grant or one year from the date of exercise (a “disqualifying disposition”), the optionee generally will realize ordinary income in the year of disposition and Hudson will receive a corresponding income tax deduction in an amount equal to the excess of (i) the lesser of (a) the amount, if any, realized on the disposition and (b) the fair market value of the shares on the date the option was exercised over (ii) the option price. Any additional gain realized on the disposition will be short-term or long-term capital gain and any loss will be long-term or short-term capital loss, as applicable. The optionee will be considered to have disposed of a share if he or she sells, exchanges, makes a gift of or transfers legal title to the share (except transfers, among others, by pledge, on death or to a spouse). If the disposition is by sale or exchange, the optionee’s tax basis will equal the amount paid for the shares plus any ordinary income realized as a result of the disqualifying disposition.

The exercise of an Incentive Stock Option may subject the optionee to the so-called “alternative minimum tax” (“AMT”). The amount by which the fair market value of the shares purchased at the time of the exercise exceeds the option exercise price is an adjustment for purposes of computing the AMT. In the event of a disqualifying disposition of the shares in the same taxable year as exercise of the Incentive Stock Option, no adjustment is then required for purposes of the AMT, but regular income tax, as described above, may result from such disqualifying disposition.

An optionee who surrenders shares as payment of the exercise price of his or her Incentive Stock Option generally will not recognize gain or loss on his or her surrender of such shares. The surrender of shares previously acquired upon exercise of an Incentive Stock Option in payment of the exercise price of another Incentive Stock Option, is, however, a “disposition” of such stock. If the Incentive Stock Option holding period requirements described above have not been satisfied with respect to such stock, such disposition will be a disqualifying disposition that may cause the optionee to recognize ordinary income as discussed above.

Under the Code, all of the shares received by an optionee upon exercise of an Incentive Stock Option by surrendering shares will be subject to the Incentive Stock Option holding period requirements. Of those shares, a number of shares (the “Exchange Shares”) equal to the number of shares surrendered by the optionee will have the same tax basis for capital gains purposes (increased by any ordinary income recognized as a result of a disqualifying disposition of the surrendered shares if they were Incentive Stock Option shares) and the same capital gains holding period as the shares surrendered.

For purposes of determining ordinary income upon a subsequent disqualifying disposition of the Exchange Shares, the amount paid for such shares will be deemed to be the fair market value of the shares surrendered. The balance of the shares received by the optionee will have a tax basis (and a deemed purchase price) of zero and a capital gains holding period beginning on the date of exercise. The Incentive Stock Option holding period for all shares will be the same as if the option had been exercised for cash.

### Non-Qualified Stock Options

Generally, there will be no U.S. federal income tax consequences to either the optionee or Hudson on the grant of Non-Qualified Stock Options pursuant to the Stock Incentive Plan. On the exercise of a Non-Qualified Stock Option, the optionee has taxable ordinary income equal to the excess of the fair market value of the shares acquired on the exercise date over the option price of the shares. Hudson will generally be entitled to a U.S. federal income tax deduction (subject to the limitations contained in Code Section 162(m)) in an amount equal to such excess, provided that Hudson complies with applicable reporting rules.

Upon the sale of stock acquired by exercise of a Non-Qualified Stock Option, optionees will realize long-term or short-term capital gain or loss depending upon their holding period for such stock. For individuals, capital losses are deductible only to the extent of capital gains for the year plus $3,000. An

28

optionee who surrenders shares in payment of the exercise price of a Non-Qualified Stock Option will not recognize gain or loss with respect to the shares so delivered unless such shares were acquired pursuant to the exercise of an Incentive Stock Option and the delivery of such shares is a disqualifying disposition. See “Incentive Stock Options.” The optionee will recognize ordinary income on the exercise of the Non-Qualified Stock Option as described above. Of the shares received in such an exchange, that number of shares equal to the number of shares surrendered have the same tax basis and capital gains holding period as the shares surrendered. The balance of shares received will have a tax basis equal to their fair market value on the date of exercise and the capital gains holding period will begin on the date of exercise.

### Stock Grants

The taxability of a Stock Grant to a participant is dependent upon the extent to which the award is restricted on the date of grant. If a Stock Grant is either “transferable” or not “subject to a substantial risk of forfeiture” (both as determined for Federal income tax purposes), a participant will recognize taxable ordinary income on the date of grant. If a Stock Grant is both non-transferable and subject to a substantial risk of forfeiture on the date of grant, then unless an election is made as described below, a participant will not recognize taxable ordinary income on the date of grant, but will at such time or times as the Stock Grant becomes either transferable or not subject to a substantial risk of forfeiture in an amount equal to the fair market value of such shares at that time. Within thirty days of receipt of a Stock Grant that is not transferable and subject to a substantial risk of forfeiture, a participant may file an election with the Internal Revenue Service to include as taxable ordinary income in the year of receipt an amount equal to the fair market value of the shares subject to the award at the time of receipt. In such event, any subsequent appreciation in the value of such shares will not be taxable as compensation to a participant upon the vesting of shares subject to the award. However, if shares subject to the award are forfeited subsequent to such election, a participant will not be entitled to a tax deduction. For purposes of determining the amount of taxable gain or loss upon a subsequent disposition of shares issued pursuant to such an award, the amount recognized as ordinary income to a participant will be treated as the cost basis for such shares. Shares which are held for more than one year after vesting (or in the event of an election as described above, the date of receipt) generally will qualify for long-term capital gain treatment.

### Performance Awards

The tax consequences of a performance award depend upon the nature of the underlying award and if and when the performance goals are achieved. If a performance award consists of a promise to deliver common stock at a future date based upon the satisfaction of certain targets, such awards will be subject to U.S. federal income taxation as ordinary income based upon the fair market value of the common stock on the date such performance awards are earned by a participant by satisfying the performance targets, provided such awards are not then subject to a substantial risk of forfeiture.

### Application of Code Section 409A to Deferred Compensation Arrangements

The Stock Incentive Plan provides that, under certain circumstances, the receipt of a benefit resulting from an award under the Stock Incentive Plan may be electively deferred by the participant (or the Administrator, as applicable) to a time that is later than the year in which such benefit becomes vested. To the extent that a participant makes such a deferral election, Section 409A of the Code, which was enacted as part of the American Jobs Creation Act of 2004 (the “Jobs Act”), subjects the deferral arrangement to certain substantive requirements including (among other items) deferral election and payment timing requirements. In the event that a deferral arrangement fails to comply with Code Section 409A in form or operation, a participant may become subject to: (i) the imposition of U.S. federal income tax (and potentially state and local income tax) on all amounts deferred in the tax year in which the amounts are deferred (or, if later, in the tax year when the receipt of the benefits are no longer subject to a substantial risk of forfeiture); (ii) a penalty tax of 20 percent of the includable amount (in addition to the regular income tax at ordinary income rates); and (iii) interest at the underpayment rate plus 1 percent from the time the amount was first deferred (or, if later, the tax year when the benefits are no longer subject to a substantial risk of forfeiture) until the time the amount is included in income. The Stock Incentive Plan specifically provides that any awards in connection therewith shall be structured in a manner (as determined by the Board) that is intended to comply with the requirements of Section 409A, and that any deferrals of payments under the Plan (whether requested by the

29

participant or otherwise required by the Compensation Committee) with respect to Awards under this Plan shall not be allowed except to the extent that such deferrals would not (in the judgment of the Board) cause the payments to fail to satisfy the requirements for nonqualified deferred compensation plans described in Section 409A of the Code. Generally speaking, Section 409A of the Code does not apply to incentive stock options and nonqualified stock options granted at fair market value if no deferral is provided beyond exercise, or to restricted stock. Because the tax consequences to any participant in the Stock Incentive Plan may depend upon such person’s situation, as well as the uncertain application of Code Section 409A, each participant in the Stock Incentive Plan should consult his or her tax advisor as to the federal, state and local and other tax consequences with respect to the grant or exercise of an option or any other award granted under the Stock Incentive Plan.

### Withholdings of Tax; Company Deduction

Generally, whenever a participant realizes ordinary income under the Stock Incentive Plan, a corresponding deduction is available to Hudson provided Hudson complies with certain reporting requirements. Under Code Section 162(m), however, Hudson will be denied a deduction for certain compensation if it exceeds $1,000,000 paid.

Hudson is entitled to withhold, or secure payment from a participant in lieu of withholding, the amount of any tax required by law to be withheld or paid by Hudson with respect to any amount payable or shares issuable under a participant’s award.

## Equity Compensation Plan Information

The following table provides certain information with respect to all of Hudson’s equity compensation plans as of December 31, 2017.

# PROPOSAL 3
ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

The Company is asking its shareholders to approve a non-binding advisory resolution on its named executive officer compensation as reported in this Proxy Statement pursuant to the Securities Exchange Act and related SEC rules and regulations. At our 2013 annual meeting of shareholders, the shareholders voted, on an advisory basis, in favor of annual votes with respect to named executive officer compensation, and our Board of Directors has agreed to implement annual votes with respect thereto.

Our compensation structure is established by our Compensation Committee and is designed to attract and retain motivated executives who substantially contribute to our long-term success and the creation of shareholder value, to reward executives when the Company performs financially or operationally well, to align the financial interests of our executives with the interests of our shareholders, and to be competitive within our industry without targeting or setting compensation at specific benchmark percentiles. Our Compensation Committee’s philosophy is to balance the named executive officers’ short-term compensation with long-term compensation in order to align their interests with the interests of our shareholders. Within this framework, our Compensation Committee strives to maintain executive compensation that is fair, reasonable, and competitive.

In accordance with the Securities Exchange Act, and as a matter of good corporate governance, the Company is asking shareholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the shareholders of Hudson Technologies, Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission in the ‘Compensation Discussion and Analysis’ and the related accompanying tabular and narrative disclosure included in the Company’s Proxy Statement for the fiscal 2018 Annual Meeting of Shareholders.

This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board. Although non-binding, the Board and the Compensation Committee values the input of our shareholders and will carefully review and consider the voting results when evaluating our named executive officer compensation program.

# PROPOSAL 4
RATIFICATION OF THE APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

BDO USA, LLP has audited and reported upon our financial statements for our fiscal year ended December 31, 2017. The Audit Committee of the Board has re-appointed BDO USA, LLP as our independent registered public accountants for the fiscal year ending December 31, 2018. Although shareholder approval of the appointment of BDO USA, LLP is not required by law, the Audit Committee and the Board believe that it is advisable to give shareholders an opportunity to ratify this appointment. In view of the difficulty and expense involved in changing auditors on short notice, however, should the shareholders not ratify the selection of BDO USA, LLP, it is contemplated that the appointment of BDO USA, LLP for the fiscal year ending December 31, 2018 will be permitted to stand unless the Audit Committee finds other compelling reasons for making a change. Disapproval by the shareholders will be considered a recommendation that the Audit Committee select other auditors for the following year. Furthermore, although the appointment of BDO USA, LLP is being submitted for shareholder ratification, the Audit Committee reserves the right, even after ratification by shareholders, to change the appointment of BDO USA, LLP as our independent registered public accountants, at any time during the 2018 fiscal year, if it deems such change to be in our best interest. A representative of BDO USA, LLP is expected to be present at the Annual Meeting with the opportunity to make a statement if he or she desires to do so and is expected to be available to respond to appropriate questions.

In addition to retaining BDO USA, LLP to audit the Company’s financial statements, we have engaged BDO USA, LLP from time to time to perform other services. The following sets forth the aggregate fees billed by BDO USA, LLP to the Company in connection with services rendered during the years ended December 31, 2017 and December 31, 2016.

Audit Fees. The aggregate fees billed by BDO USA, LLP for professional services rendered for the audits and reviews of the Company’s financial statements for the years ended December 31, 2017 and 2016 totaled $1,068,540 and $482,070, respectively.

Audit-Related Fees. In 2017 and 2016, the aggregate fees billed by BDO USA, LLP for assurance and related services that are reasonably related to the performance of the audit or review of the Company’s financial statements were $388,265 and $90,100, respectively. The fees in 2017 were related to the due diligence process with respect to the Company’s recent acquisition of Airgas-Refrigerants, Inc. and the audit of the Company's employee benefit plan. The fees in 2016 were related to the audit of the Company's employee benefit plan.

Tax Fees. In 2017 and 2016 the aggregate fees billed by BDO USA, LLP for professional services rendered for tax advice totaled $49,780 and $40,000, respectively.

All Other Fees. In 2017 and 2016, all other fees billed by BDO USA LLP for professional services rendered other than the services described in the paragraphs caption “Audit Fees”, “Audit Related Fees” and “Tax Fees” were none and none, respectively.

The Audit Committee has established its pre-approval policies and procedures, pursuant to which the Audit Committee approved the foregoing services provided by BDO USA, LLP in 2017. Consistent with the Audit Committee’s responsibility for engaging the Company’s independent auditors, all audit and permitted non-audit services require pre-approval by the Audit Committee. The full Audit Committee approves proposed services and fee estimates for these services. The Audit Committee chairperson or their designee has been designated by the Audit Committee to approve any services arising during the year that were not pre-approved by the Audit Committee.

Appendix A

# HUDSON TECHNOLOGIES, INC.
2018 STOCK INCENTIVE PLAN

1. Purpose

The 2018 Hudson Technologies, Inc. Stock Incentive Plan (the “Plan”) is intended to provide incentives which will attract, retain, motivate and reward highly competent persons as non-employee directors, executive officers and other employees of, or consultants and advisors to, Hudson Technologies, Inc. (the “Company”) or any of its subsidiary corporations, limited liability companies or other forms of business entities now existing or hereafter formed or acquired (“Subsidiaries”), by providing them opportunities to acquire shares of common stock, par value $.01 per share, of the Company (“Common Stock”) or to receive other Awards (as defined in Section 4 below) described herein. Furthermore, the Plan is intended to assist in further aligning the interests of such non-employee directors, executive officers and other employees, consultants and advisors, with those of the stockholders of the Company.

2. Administration

a. The Plan generally shall be administered by a committee (the “Committee”) which shall be the Compensation Committee of the Board of Directors of the Company (the “Board”) or another committee appointed by the Board from among its members. In the absence of such committee, the Board shall administer the Plan. Unless the Board determines otherwise, the Committee shall be comprised of at least two members. All members of the Committee shall (i) meet the independence requirements of applicable law and the rules and regulations of the Nasdaq Stock Market (“Nasdaq”), and (ii) qualify as “outside” directors within the meaning of Internal Revenue Code Section 162(m) and as “non-employee” directors within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended. The Committee is authorized, subject to the provisions of the Plan, to establish such rules and regulations as it deems necessary for the proper administration of the Plan and to make such determinations and interpretations and to take such action in connection with the Plan and any Awards granted hereunder as it deems necessary or advisable. All determinations and interpretations made by the Committee shall be binding and conclusive on all persons and entities, including participants and their legal representatives. However, the Board shall have the authority to establish the level of stock options or stock awards granted under the Plan, as well as stock grant levels and stock ownership guidelines, for the non-employee directors.

b. No member of the Board, no member of the Committee or subcommittee thereof, and no agent of the Committee who is an employee of the Company, shall be liable for any act or failure to act hereunder, except in circumstances involving his or her bad faith, gross negligence or willful misconduct, or for any act or failure to act hereunder by any other member or employee or by any agent to whom duties in connection with the administration of this Plan have been delegated. The Company shall indemnify members of the Board, members of the Committee and any agent of the Committee who is an employee of the Company against any and all liabilities or expenses to which they may be subjected by reason of any act or failure to act with respect to their duties on behalf of the Plan, except in circumstances involving such person’s bad faith, gross negligence or willful misconduct.

c. The Committee shall have the authority to grant Awards to non-employee directors, executive officers and other employees of, or consultants and advisors to, the Company or any of its Subsidiaries. The Committee (i) may delegate to one or more of its members, or to one or more agents, such administrative duties as it may deem advisable, and (ii) may delegate any of its responsibilities to a subcommittee comprised of one or more members of the Committee or to the CEO, including, but not limited to, the authority to make grants of awards of stock rights or options to any officer or employee of the Company, other than officers subject to Section 16 of the Securities Exchange Act of 1934, under the Plan, as the Committee deems appropriate. The Committee, or any person to whom it has delegated duties as aforesaid, may employ one or more persons to render advice with respect to any responsibility the Committee or such person may have under the Plan. The Committee may employ such legal or other counsel, consultants and agents as it may deem desirable for the administration of the Plan and may rely upon any opinion or computation received from any such counsel, consultant or agent. Expenses incurred by the Committee in the engagement of such

A-1

counsel, consultant or agent shall be paid by the Company or any of its Subsidiaries whose employees have benefited from the Plan, as determined by the Committee.

3. Participants

Participants shall consist of such non-employee directors, executive officers and other employees of, or consultants and advisors to, the Company or any of its Subsidiaries and outside contractors who the Committee in its sole discretion determines to be significantly responsible for the success and future growth and profitability of the Company and who the Committee may designate from time to time to receive Awards under the Plan. Designation as a participant in any year shall not require the Committee to designate such person to receive an Award in any other year or, once designated, to receive the same type or amount of Award as granted to the participant in any other year. The Committee shall consider such factors as it deems pertinent in selecting participants and in determining the type, amount and other terms of Awards.

4. Types of Awards and Vesting Restrictions

Awards under the Plan may be granted in any one or a combination of (1) Stock Options, (2) Stock Grants, and (3) Performance Awards (individually an “Award,” and collectively, “Awards”). Awards shall be evidenced by Award agreements (which need not be identical) in such forms as the Committee may from time to time approve; provided, however, that in the event of any conflict between the provisions of the Plan and any such agreements, the provisions of the Plan shall prevail.

5. Common Stock Available Under the Plan

a. Shares Available. The aggregate number of shares of Common Stock that may be subject to Awards, including shares of Common Stock underlying Stock Options, granted under this Plan shall be 4,000,000 shares of Common Stock, which may be authorized and unissued or treasury shares, subject to any adjustments made in accordance with Section 9 below. Notwithstanding the preceding sentence, but subject to adjustments pursuant to Section 9 below, the number of shares that are available for incentive stock options (“Incentive Stock Options”) within the meaning of Section 422 of the Code shall be determined by reducing the number of shares designated in the preceding sentence by the number of shares issued under the Plan, or granted pursuant to outstanding Awards (whether or not shares are issued pursuant to such Awards), provided that any shares that are either issued or purchased under the Plan and forfeited back to the Plan, or surrendered in payment of the Exercise Price for an Award or in connection with a tax withholding right shall be available for issuance pursuant to future incentive stock options.

b. Maximum Limits. The maximum number of shares of Common Stock with respect to which Awards may be granted or measured to any participant during any fiscal year of the Company shall not exceed 750,000 shares, subject to any adjustment made in accordance with Section 10 below.

c. Shares Underlying Awards That Again Become Available. Any shares of Common Stock subject to a Stock Option, Stock Grant or Performance Award, which for any reason are cancelled, forfeited, or surrendered to the Company, shall again be available for Awards under the Plan. The preceding sentence shall apply only for purposes of determining the aggregate number of shares of Common Stock subject to Awards pursuant to Section 5.a above but shall not apply for purposes of determining the maximum number of shares of Common Stock subject to Awards that any individual participant may receive pursuant to Section 5.b above.

6. Stock Options

a. In General. The Committee is authorized to grant Stock Options to non-employee directors, executive officers and other employees of, or consultants or advisors to, the Company or any of its Subsidiaries and shall, in its sole discretion, determine which of such individuals shall receive Stock Options and the number of shares of Common Stock underlying each Stock Option. Stock Options may be (i) Incentive Stock Options, or (ii) Stock Options which do not qualify as Incentive Stock Options (“Non-Qualified Stock Options”). The Committee may grant to a participant in the Plan one or more Incentive Stock Options, Non-Qualified Stock Options, or both types of Stock Options. Each Stock Option shall be subject to such terms and conditions consistent with the Plan as shall be determined by the Committee and as set forth in the Award agreement. In addition, each Stock Option shall be subject to the following limitations set forth in this Section 6.

A-2

b. Exercise Price. Each Stock Option granted hereunder shall have such per-share exercise price as the Committee may determine on the date of grant; provided, however, subject to Section 6(e) below, that the per-share exercise price shall not be less than 100 percent of the Fair Market Value (as defined in Section 14 below) of Common Stock on the date the Stock Option is granted.

c. Payment of Exercise Price. Unless otherwise provided by the Committee, the Stock Option exercise price must be paid in cash. In the discretion of the Committee, a payment may also be made by delivering a properly executed exercise notice to the Company together with a copy of irrevocable instructions to a broker to deliver promptly to the Company the amount of sale or loan proceeds to pay the exercise price with the requirement of the broker same day reconciliation or as otherwise determined by the Company. To facilitate the foregoing, the Company may enter into agreements for coordinated procedures with one or more brokerage firms. The Committee may prescribe any other method of paying the exercise price that it determines to be consistent with applicable law and the purpose of the Plan.

d. Exercise Period. Stock Options granted under the Plan shall be exercisable at such time or times as specified in the Plan and the Award agreement; provided, however, that no Stock Option shall be exercisable later than ten years after the date it is granted.

e. Limitations on Incentive Stock Options. Incentive Stock Options may be granted only to participants who are executive officers or other employees of the Company or any of its Subsidiaries on the date of grant. The aggregate market value (determined as of the time the Stock Option is granted) of Common Stock with respect to which Incentive Stock Options (under all option plans of the Company) are exercisable for the first time by a participant during any calendar year shall not exceed $100,000. For purposes of the preceding sentence, Incentive Stock Options shall be taken into account in the order in which they are granted. Incentive Stock Options may not be granted to any participant who, at the time of grant, owns stock possessing (after the application of the attribution rules of Section 424(d) of the Code) more than 10 percent of the total combined voting power of all outstanding classes of stock of the Company or any of its Subsidiaries, unless the exercise price is fixed at not less than 110 percent of the Fair Market Value of Common Stock on the date of grant and the exercise of such option is prohibited by its terms after the expiration of five years from the date of grant of such option.

f. Alternative Settlement of Option. If provided in an Award agreement, or upon the receipt of written notice of exercise, or as otherwise provided for by the Board or Committee, as the case may be, either at or after the time of grant of the Stock Option, the Board or the Committee, as the case may be, may elect to settle all or part of any Stock Option by paying to the optionee an amount, in cash or Stock (valued at Fair Market Value on the date of exercise), equal to the product of the excess of the Fair Market Value of one share of Stock, on the date of exercise over the Stock Option exercise price, multiplied by the number of shares of Stock with respect to which the optionee proposes to exercise the Option. Any such settlements which relate to Options which are held by optionees who are subject to Section 16(b) of the Exchange Act shall comply with Rule 16b-3, to the extent applicable, and with such other conditions as the Board or Committee, as the case may be, may impose.

7. Stock Grants

The Committee is authorized to grant Stock Grants to non-employee directors, executive officers and other employees of, or consultants or advisors to, the Company or any of its Subsidiaries and shall, in its sole discretion, determine which of such individuals shall receive Stock Grants and the number of shares of Common Stock underlying each Stock Grant. Each Stock Grant shall be subject to such terms and conditions consistent with the Plan as shall be determined by the Committee and as set forth in the Award agreement, including, without limitation, restrictions on the sale or other disposition of such shares, and the right of the Company to reacquire such shares for no consideration upon termination of the participant’s employment with, or services performed for, the Company or any of its Subsidiaries within specified periods. The Committee may require the participant to deliver a duly signed stock power, endorsed in blank, relating to Common Stock covered by such Stock Grant and/or that the stock certificates evidencing such shares be held in custody or bear restrictive legends until the restrictions thereon shall have lapsed. The Award agreement shall specify

A-3

whether the participant shall have, with respect to the shares of Common Stock subject to a Stock Grant, all of the rights of a holder of shares of Common Stock, including the right to receive dividends, if any, and to vote the shares.

8. Performance Awards

a. In General. The Committee is authorized to grant Performance Awards to executive officers and other employees of the Company or any of its Subsidiaries and shall, in its sole discretion, determine such executive officers and other employees who will receive Performance Awards and the number of shares of Common Stock that may be subject to each Performance Award. Each Performance Award shall be subject to such terms and conditions consistent with the Plan as shall be determined by the Committee and as set forth in the Award agreement. The Committee shall set performance targets at its discretion which, depending on the extent to which they are met, will determine the number and/or value of Performance Awards that will be paid out to the participants, and may attach to such Performance Awards one or more restrictions. Performance targets may be based upon, without limitation, Company-wide, divisional and/or individual performance.

b. Payout. Payment of earned Performance Awards may be made in shares of Common Stock or in cash and shall be made in accordance with the terms and conditions prescribed or authorized by the Committee. Subject to Section 20 below, if permitted by the Committee, the participant may elect to defer, or the Committee may require or permit the deferral of, the receipt of Performance Awards upon such terms as the Committee deems appropriate.

9. Adjustment Provisions

If there shall be any change in Common Stock of the Company, through merger, consolidation, reorganization, recapitalization, stock dividend, stock split, reverse stock split, split up, spinoff, combination of shares, exchange of shares, dividend in kind or other like change in capital structure or distribution (other than normal cash dividends) to stockholders of the Company, an adjustment shall be made to each outstanding Stock Option such that each such Stock Option shall thereafter be exercisable for such securities, cash and/or other property as would have been received in respect of Common Stock subject to such Stock Option had such Stock Option been exercised in full immediately prior to such change or distribution, and such an adjustment shall be made successively each time any such change shall occur. In addition, in the event of any such change or distribution, in order to prevent dilution or enlargement of participants’ rights under the Plan, the Committee shall adjust, in an equitable manner, the number and kind of shares that may be issued under the Plan, the number and kind of shares subject to outstanding Awards, the exercise price applicable to outstanding Awards, and the Fair Market Value of Common Stock and other value determinations applicable to outstanding Awards. To the extent consistent with the requirements for satisfying the requirements of Section 162(m) of the Code, if applicable, appropriate adjustments may also be made by the Committee in the terms of any Awards under the Plan to reflect such changes or distributions and to modify any other terms of outstanding Awards on an equitable basis, including modifications of performance targets and changes in the length of performance periods. In addition, the Committee is authorized to make adjustments to the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events affecting the Company or any of its Subsidiaries or the financial statements of the Company, or in response to changes in applicable laws, regulations, or accounting principles. Notwithstanding the foregoing, (i) any adjustment with respect to an Incentive Stock Option shall comply with the rules of Section 424(a) of the Code, and (ii) in no event shall any adjustment be made which would render any Incentive Stock Option granted hereunder other than an incentive stock option for purposes of Section 422 of the Code.

10. Change in Control

a. Accelerated Vesting. Notwithstanding any other provision of this Plan, if there is a Change in Control of the Company (as defined in Section 10(b) below), all unvested Awards granted under the Plan shall become fully vested immediately upon the occurrence of the Change of Control and such vested Awards shall be paid out or settled, as applicable, within 60 days upon the occurrence of the Change of Control, subject to requirements of applicable laws and regulations.

b. Definition. For purposes of this Section 10, (i) if there is an employment agreement or a change-in-control agreement between the participant and the Company or any of its Subsidiaries in effect,

A-4

“Change in Control” shall have the same definition as the definition of “change in control” contained in such employment agreement or change-in-control agreement, or (ii) if “Change in Control” is not defined in such employment agreement or change-in-control agreement, or if there is no employment agreement or change-in-control agreement between the participant and the Company or any of its Subsidiaries in effect, a “Change in Control” of the Company shall be deemed to have occurred upon any of the following events:

(1) any person or other entity (other than any of the Company’s Subsidiaries or any employee benefit plan sponsored by the Company or any of its Subsidiaries) including any person as defined in Section 13(d)(3) of the Exchange Act, becomes the beneficial owner, as defined in Rule 13d-3 under the Exchange Act, directly or indirectly, of more than 50 percent of the total combined voting power of all classes of capital stock of the Company normally entitled to vote for the election of directors of the Company (the “Voting Stock”);

(2) the stockholders of the Company approve the sale of all or substantially all of the property or assets of the Company and such sale occurs;

(3) the Company’s Common Stock shall cease to be publicly traded;

(4) the stockholders of the Company approve a consolidation or merger of the Company with another corporation (other than with any of the Company’s Subsidiaries), the consummation of which would result in the stockholders of the Company immediately before the occurrence of the consolidation or merger owning, in the aggregate, less than 51 percent of the Voting Stock of the surviving entity, and such consolidation or merger occurs; or

(5) a change in the Company’s Board occurs with the result that the members of the Board on the Effective Date (as defined in Section 23(a) below) of the Plan (the “Incumbent Directors”) no longer constitute a majority of such Board, provided that any person becoming a director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest or the settlement thereof, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose election or nomination for election was supported by two-thirds (2/3) of the then Incumbent Directors shall be considered an Incumbent Director for purposes hereof.

c. Cashout. The Committee, in its discretion, may determine that, upon the occurrence of a Change in Control of the Company, each Stock Option outstanding hereunder shall terminate and such holder shall receive, within 60 days upon the occurrence of the Change of Control, with respect to each share of Common Stock subject to such Stock Option, an amount equal to the excess of the Fair Market Value of such shares of Common Stock immediately prior to or upon the occurrence of such Change in Control over the exercise price per share of such Stock Option; such amount to be payable in cash, in one or more kinds of property (including the property, if any, payable in the transaction) or in a combination thereof, as the Committee, in its discretion, shall determine.

11. Termination of Employment

a. Subject to any written agreement between the participant and the Company or any of its Subsidiaries, if a participant’s employment is terminated due to death or disability:

(1) all unvested Stock Grants held by the participant on the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, shall immediately become vested as of such date;

(2) all unexercisable Stock Options held by the participant on the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, shall immediately become exercisable as of such date and shall remain exercisable until the earlier of (i) the end of the one-year period following the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, or (ii) the date the Stock Option would otherwise expire;

(3) all exercisable Stock Options held by the participant on the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, shall remain

A-5

exercisable until the earlier of (i) the end of the one-year period following the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, or (ii) the date the Stock Option would otherwise expire; and

(4) all unearned and/or unvested Performance Awards held by the participant on the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, with regard to which a minimum of one year of the performance period (as defined by the Committee) has elapsed, shall immediately become earned or vested as of such date and shall be paid out and/or settled based on the participant’s performance immediately prior to the date of the participant’s death or the date of the termination of his or her employment due to disability, as the case may be, on a pro-rated basis.

b. Subject to any written agreement between the participant and the Company or any of its Subsidiaries, if a participant’s employment is terminated by the Company for Cause (as defined in Section 11(f) below), or if a participant voluntarily terminates the participant’s employment, all Awards, whether or not vested, earned or exercisable, held by the participant on the date of the termination of his or her employment for Cause, or on the date of the participant’s voluntary termination of employment, shall immediately be canceled as of such date.

c. Subject to any written agreement between the participant and the Company or any of its Subsidiaries, if a participant’s employment is terminated for any reason other than as provided in Section 11(b) above, or other than due to death or disability:

(1) all unvested, unearned or unexercisable Awards held by the participant on the date of the termination of his or her employment shall immediately be forfeited by such participant as of such date; and

(2) all exercisable Stock Options held by the participant on the date of the termination of his or her employment shall remain exercisable until the earlier of (i) the end of the 90-day period following the date of the termination of the participant’s employment, or (ii) the date the Stock Option would otherwise expire.

d. Notwithstanding anything contained in the Plan to the contrary, the Committee may, in its discretion, provide that:

(1) any or all unvested Stock Grants held by the participant on the date of the termination of the participant’s employment shall immediately become vested as of such date;

(2) any or all unexercisable Stock Options held by the participant on the date of the participant’s death and/or the date of the termination of his or her employment shall immediately become exercisable as of such date and shall remain exercisable until a date that occurs on or prior to the date the Stock Option is scheduled to expire, provided, however, that Incentive Stock Options shall remain exercisable not longer than the end of the 90-day period following the date of the termination of the participant’s employment;

(3) any or all exercisable Stock Options held by the participant on the date of the participant’s death and/or the date of the termination of his or her employment shall remain exercisable until a date that occurs on or prior to the date the Stock Option is scheduled to expire, provided, however, that Incentive Stock Options shall remain exercisable not longer than the end of the 90-day period following the date of the termination of the participant’s employment; and/or

(4) a participant shall immediately become vested in all or a portion of any earned Performance Awards held by such participant on the date of the termination of the participant’s employment, and such vested Performance Awards (or portion thereof) and/or any unearned Performance Awards (or portion thereof) held by such participant on the date of the termination of his or her employment shall immediately become payable to such participant as if all performance goals had been met as of the date of the termination of his or her employment.

A-6

e. Notwithstanding anything contained in the Plan to the contrary, (i) the provisions contained in this Section 11 shall be applied to an Incentive Stock Option only if the application of such provision maintains the treatment of such Incentive Stock Option as an Incentive Stock Option and (ii) the exercise period of an Incentive Stock Option in the event of a termination due to disability provided in Section 11(a)(3) above shall only apply if the participant’s disability satisfies the requirement of “permanent and total disability” as defined in Section 22(e)(3) of the Code.

f. For purposes of this Section 11, (i) if there is an employment agreement between the participant and the Company or any of its Subsidiaries in effect, “Cause” shall have the same definition as the definition of “cause” contained in such employment agreement; or (ii) if “Cause” is not defined in such employment agreement or if there is no employment agreement between the participant and the Company or any of its Subsidiaries in effect, “Cause” shall include, but is not limited to:

(1) any willful and continuous neglect of or refusal to perform the employee’s duties or responsibilities with respect to the Company or any of its Subsidiaries, insubordination, dishonesty, gross neglect or willful malfeasance by the participant in the performance of such duties and responsibilities, or the willful taking of actions which materially impair the participant’s ability to perform such duties and responsibilities, or any serious violation of the rules or regulations of the Company;

(2) the violation of any local, state or federal criminal statute, including, without limitation, an act of dishonesty such as embezzlement, theft or larceny;

(3) intentional provision of services in competition with the Company or any of its Subsidiaries, or intentional disclosure to a competitor of the Company or any of its Subsidiaries of any confidential or proprietary information of the Company or any of its Subsidiaries; or

(4) any similar conduct, including, without limitation, disparagement of the Company or any of its Subsidiaries, by the participant with respect to which the Company determines in its discretion that the participant has terminated employment under circumstances such that the payment of any compensation attributable to any Award granted under the Plan would not be in the best interest of the Company or any of its Subsidiaries.

For purposes of this Section 11, the Committee shall have the authority to determine whether the “Cause” exists and whether subsequent actions on the part of the participant have cured the “Cause.”

12. Transferability

Each Award granted under the Plan to a participant who is subject to restrictions on transferability and/or exercisability shall not be transferable otherwise than by will or the laws of descent and distribution and/or shall be exercisable, during the participant’s lifetime, only by the participant. In the event of the death of a participant, each Stock Option theretofore granted to him or her shall be exercisable in accordance with Section 11 above and then only by the executor or administrator of the estate of the deceased participant or the person or persons to whom the deceased participant’s rights under the Stock Option shall pass by will or the laws of descent and distribution. Notwithstanding the foregoing, at the discretion of the Committee, an Award (other than an Incentive Stock Option) may permit the transferability of such Award by a participant solely to members of the participant’s immediate family or trusts or family partnerships for the benefit of such persons, subject to any restriction included in the Award agreement.

13. Other Provisions

Awards granted under the Plan may also be subject to such other provisions (whether or not applicable to the Award granted to any other participant) as the Committee determines on the date of grant to be appropriate, including, without limitation, for the installment purchase of Common Stock under Stock Options to assist the participant, excluding an executive officer or a director, in financing the acquisition of Common Stock, for the forfeiture of, or restrictions on resale or other disposition of, Common Stock acquired under any form of the Award, for the acceleration of exercisability or vesting of Awards in the event of the Change in Control of the Company, or to comply with federal and state securities laws, or understandings or conditions as to the participant’s employment, in addition to those specifically provided for under the Plan. In addition, except as otherwise provided herein (including, without limitation Section 20 hereof), a participant may defer

A-7

receipt or payment of any Award granted under this Plan, in accord with the terms of any deferred compensation plan or arrangement of the Company. The Committee shall have the authority to retract any Award granted under the Plan in case of a material restatement of the financial statements of the Company, or as otherwise required by law.

14. Fair Market Value

For purposes of this Plan and any Awards granted hereunder, Fair Market Value shall be (i) the closing price of Common Stock on the date of grant in the case of a Stock Option or date of reference for any other Award (or on the last preceding trading date if Common Stock was not traded on such date) if Common Stock is readily tradable on a national securities exchange or other market system or (ii) if Common Stock is not readily tradable, the amount determined in good faith by the Committee as the fair market value of Common Stock.

15. Withholding

All payments or distributions of Awards made, and if applicable any shares of Common Stock issued, pursuant to the Plan shall be subject to satisfaction of tax witholding pursuant to applicable federal, state and local or foreign tax withholding requirements. If the Company proposes or is required to distribute Common Stock pursuant to the Plan or a participant, it may require the participant receiving such Common Stock to remit to it or to the Subsidiary that employs such participant an amount sufficient to satisfy such tax withholding requirements prior to the delivery of any certificates for such Common Stock. In lieu thereof, the Company or the Subsidiary employing the participant shall have the right to withhold the amount of such taxes from any other sums due or to become due from the Company or the Subsidiary, as the case may be, to the participant receiving Common Stock, as the Committee shall prescribe. The Committee may, in its discretion, and subject to such rules as the Committee may adopt (including any as may be required to satisfy applicable tax and/or non-tax regulatory requirements), permit a participant to pay all or a portion of the federal, state and local or foreign withholding taxes arising in connection with any Award consisting of, or resulting in the issuance of, shares of Common Stock, including Common Stock that is part of the Award that gives rise to the withholding requirement, by electing to have the Company withhold shares of Common Stock having a Fair Market Value equal to the amount of tax to be withheld, such tax calculated at rates required by statute or regulation.

16. Tenure

A participant’s right, if any, to continue to serve the Company or any of its Subsidiaries as a non-employee director, executive officer, other employee, consultant or advisor or otherwise shall not be enlarged or otherwise affected by his or her designation as a participant under the Plan.

17. Unfunded Plan

Participants shall have no right, title, or interest whatsoever in or to any investments which the Company may make to aid it in meeting its obligations under the Plan. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company and any participant, beneficiary, legal representative or any other person. To the extent that any person acquires a right to receive payments from the Company under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company. All payments to be made hereunder shall be paid from the general funds of the Company and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in the Plan. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974, as amended.

18. No Fractional Shares

No fractional shares of Common Stock shall be issued or delivered pursuant to the Plan or any Award. The Committee shall determine whether cash, or Awards, or other property shall be issued or paid in lieu of fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.

19. Duration, Amendment and Termination

No Award shall be granted more than ten years after the Effective Date; provided, however, that the terms and conditions applicable to any Award granted prior to such date may thereafter be amended or modified by mutual agreement between the Company and the participant or such other persons as may then have an interest therein. Also, by mutual agreement between the Company and a participant under this Plan or under any other present or future plan of the Company, Awards may be granted to such participant in substitution and exchange for, and in cancellation of, any Awards previously granted to such participant under this Plan, or any other present or future plan of the Company. The Board or the Committee may amend the Plan from time to time or suspend or terminate the Plan at any time. However, no action authorized by this Section 19 shall reduce the amount of any existing Award or change the terms and conditions thereof without the participant’s consent. No amendment of the Plan shall, without approval of the stockholders of the Company, (i) increase the total number of shares which may be issued under the Plan or the maximum number of shares with respect to Stock Options and other Awards that may be granted to any individual under the Plan; (ii) modify the requirements as to eligibility for Awards under the Plan; or (iii) effect the repricing of Stock Options; provided, however, that no amendment may be made without approval of the stockholders of the Company if the amendment will disqualify any Incentive Stock Options granted hereunder.

20. Compliance with Section 409A of the Code

Notwithstanding anything to the contrary set forth herein, any Award granted under this Plan that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Award shall comply with the requirements of Section 409A if the Code. Such restrictions, if any, shall be determined by the Board. For example, any deferrals of payments to any participant (whether requested by the participant of otherwise required by the Committee) with respect to Awards under this Plan shall not be allowed except to the extent that such deferrals would not cause the payments to fail to satisfy the requirements for nonqualified deferred compensation plans described in Section 409A of the Code.

21. Governing Law

This Plan, Awards granted hereunder and actions taken in connection herewith shall be governed and construed in accordance with the laws of the State of New York (regardless of the law that might otherwise govern under applicable New York principles of conflict of laws).

22. Severability

In case any provision of this Plan shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

23. Effective Date

a. The Plan shall be effective as of the date on which the Plan is approved by the stockholders of the Company at an annual meeting or any special meeting of stockholders of the Company (the “Effective Date”) and such approval of stockholders shall be a condition to the right of each participant to receive Awards hereunder.

b. This Plan shall terminate on the 10th anniversary of the Effective Date (unless sooner terminated by the Board).
