The Compensation Committee members are not officers or employees of our company, and there is not, nor was there during fiscal 2021, any compensation committee interlock (in other words, no executive of our company serves as a Director or on the compensation committee of a company that has one or more executives serving on our Board or our Compensation Committee).

The Committee’s goal is to nominate candidates who possess a range of experiences and backgrounds which will contribute to the board’s overall effectiveness in meeting its duties and forwarding the goals of our company.

The Board is responsible for identifying individuals qualified to become Directors, and nominees are selected by the Board. The Board takes into account many factors, including being highly qualified in terms of business experience, finance and other disciplines relevant to the success of a publicly traded company in today’s business environment; understanding of the Company’s business on a technical level and the industry in which it competes; and educational and professional background. The Board evaluates each individual in the context of the Board as a whole, with the objective of recommending a group that can best support the success of the business and, based on its diversity of experience and backgrounds, represent stockholder interests through the exercise of sound judgment.

The Nominating Committee will consider a Director candidate recommended by a shareholder. A candidate must be highly qualified based on the factors noted above and be both willing and expressly interested in serving on the Board. A shareholder wishing to recommend a candidate for the Committee’s consideration must follow Securities and Exchange Commission Rule 14a-8 or our advance notice provisions contained in our Bylaws.

The Board has determined that each of the following four members of the Board is “independent” within the meaning of applicable listing standards of the NYSE and under the standards, set forth in Exhibit A to our Environmental Social and Governance and Personnel Development Charter which are consistent with the NYSE listing standards: Leslie A. Beyer, Nigel J. Jenvey, David L. Bradshaw, and John Chisholm. The Board has made an affirmative determination that each of Directors named above satisfies these categorical standards. In making its determination, the Board examined relationships between Directors or their affiliates with us and our affiliates and determined that each such relationship, if any, did not impair the Director’s independence. A copy of Exhibit A to our Governance Charter is available at our website, www.ngsgi.com, under the heading “Investor Relations-Governance.”

The Company values diversity and the benefits that a diverse workforce can bring to the Company and to the Board of Directors. Diversity can promote the inclusion of different perspectives and ideas which can lead to more robust discussion regarding strategic and governance policy alternatives and, ultimately, result in better corporate governance and decision making.

The Company seeks to maintain a Board comprised of talented and dedicated Directors with a diverse mix of expertise, experience, skills and backgrounds. The skills and backgrounds collectively represented on the Board should reflect the diverse nature of the business environment in which the Company operates. As new members of the Board are considered, diversity considerations should include - but not be limited to - business expertise, geography, age, gender and ethnicity.

The Company is committed to a merit-based system for Board composition within a diverse and inclusive culture which solicits multiple perspectives and views and is free of conscious or unconscious bias. When assessing Board composition or identifying suitable candidates for appointment to the Board, the Company will consider candidates on merit with due consideration to the benefits of diversity and the needs of the Board. The Board and its Nominating Committee are especially cognizant of the benefits of gender and ethnic diversity and will continue to focus on important diversity metrics in future searches.

(1) The amounts shown on these rows reflects the awards of restricted stock or units earned in 2021, to be issued in 2022, contingent upon the approval by our shareholders of a proposal to increase the number of shares of common stock reserved for issuance under the 2019 Plan that we intend to submit for a vote at our 2022 annual meeting of shareholders. To the extent we are unable to obtain shareholder approval to increase the reserved shares under the 2019 Plan, we intend to pay the value of the award in cash as they vest.

(2) The amounts on these rows assume, under the structure of our Annual Incentive Bonus Plan, that each of the metrics are achieved under threshold (75% payout), target (100% payout), and maximum / stretch (125% payout) levels. The actual payouts in April 2022 that were earned in 2021 were as follows: Mr. Taylor - $397,800, Mr. Hazlett - $73,158 and Mr. Foster $78,000.

In 2006, the Committee adopted an Annual Incentive Bonus Plan or, the “IBP,” that provides guidelines for the calculation of annual non-equity incentive based compensation in the form of cash bonuses to our executives, subject to Committee oversight and modification. The bonuses awarded under the IBP are short-term awards in recognition of the overall performance and efforts made by certain of our executives during a particular year. Each year, the Committee approves the group of executives eligible to participate in the IBP and establishes target award opportunities for such executives. For 2021, the Committee maintained Mr. Taylor’s target award opportunity at 100% of his base salary. Target award opportunity was 50% of average base salary for Mr. Hazlett and Mr. Foster.

(1) Cash flow from operations is an indicator of operating performance and is defined as the Company's rental and service and maintenance gross margins, before depreciation, less selling, general and administrative expenses adjusted to exclude (i) non-cash charges related to the Company's Non-qualified Deferred Compensation Plan, (ii) non-cash stock compensation expenses and (iii) director and officer cash long-term incentive compensation expenses.

The following table sets forth the maximum bonus eligibility set by the Committee for 2021 for each of our named executive officers, and based upon the payout percentages noted in the table above, the bonus payout amount earned by each named executive for 2021 under our Annual Incentive Bonus Plan:


Criteria	Actual 2021 Performance		Target Metric		Stretch Metric		Eligible Bonus Payment Percentage		Bonus Component		Payable Bonus

(1)Cash flow from operations is an indicator of operating performance and is defined as the Company's rental and service and maintenance gross margins, before depreciation, less selling, general and administrative expenses adjusted to exclude (i) non-cash charges related to the Company's Non-qualified Deferred Compensation Plan, (ii) non-cash stock compensation expenses and (iii) director and officer cash long-term incentive compensation expenses.

In 2021, our executives received (i) no payout on cash flow from operations, as the Company's $20.3 million in cash flow from operations did not exceed its threshold achievement level of $22.4 million; (ii) a threshold financial metric payout on revenues, as the Company's $72.4 million in revenue met the target of $71.5 million but was below the stretch revenue of $73.2 million; (iii) a threshold payout on ESG objectives as management's performance met the board approved metrics; and (iv) a threshold payout on strategic and tactical initiatives as the committee considered the Company's 2021 financial and operational performance as the individual performance of all three executives related to ensuring safe and continuous operations of the Company during the economic, industry and public health challenges presented by the COVID-19 pandemic.

Our 1998 Stock Option Plan, as amended and restated, provides for the issuance of stock options to purchase up to 1,000,000 shares of our common stock. The purpose of this plan is to attract and retain the best available personnel for positions of substantial responsibility and to provide long-term incentives to employees and consultants and to promote the long-term growth and success of our business. The plan is administered by the Compensation Committee of the Board of Directors. At its discretion, the Compensation Committee determines the persons to whom stock options may be granted and the terms upon which options will be granted. In addition, the Compensation Committee may interpret the plan and may adopt, amend and rescind rules and regulations for its administration. Option awards are generally granted with an exercise price equal to the closing price of our common stock at the date of grant and generally vest based on three years of continuous service and have ten-year contractual terms.

As of December 31, 2021, stock options to purchase a total of 200,834 shares of our common stock were outstanding under the 1998 Stock Option Plan, as amended and restated, and a total of 345,003 shares of common stock were available at December 31, 2021 for future grants of stock options under the plan. Since the beginning of 2022, we have issued 2,500 stock options to purchase shares of our common stock with an additional 12,500 stock options that were either forfeited or expired, leaving 355,003 shares available under the 1998 Stock Option Plan as of April 29, 2022.

On June 20, 2019, the Company's shareholders approved our 2019 Equity Incentive Plan ("2019 Plan"). Except with respect to awards then outstanding, unless sooner terminated by the Board, the Plan will expire on the tenth anniversary of the date it was approved by shareholders (June 20, 2029) and no further awards may be granted after such date. The purposes of the 2019 Plan are to enable the Company to attract and retain the types of employees, consultants and Directors who will contribute to the Company’s long range success; provide incentives that align the interests of employees, consultants and Directors with those of the shareholders of the Company; and promote the success of the Company’s business.

The following summary of the material terms of the 2019 Plan is qualified in its entirety by the full text of the 2019 Plan, a copy of which was filed with our proxy statement for 2019 and may be obtained, free of charge, by writing to the Company, Attention: Alicia Dada, Investors Relations, 404 Veterans Airpark Lane, Suite 300, Midland, Texas 79705.

Shares Available for Awards and Limits on Awards. The Company has reserved an aggregate of 500,000 shares of common stock to be awarded under the 2019 Plan. Up to 250,000 of these shares may be issued under the 2019 Plan, in the aggregate, through the exercise of incentive stock options. No non-employee Director may be granted awards, during any fiscal year, with respect to shares of common stock that, together with any cash fees paid to the Director during the fiscal year, have a total value that exceeds $250,000 (calculating the value of any awards based on the grant date fair value for financial reporting purposes).

As of March 31, 2022, we have issued 456,198 shares under the 2019 Plan. Of these shares, 287,011 have vested and are no longer subject to any restrictions or possible forfeiture and 3,333 shares were forfeited and returned to the pool. Vested shares include shares that were withheld for taxes and, under the terms of the 2019 Plan, cannot be re-issued. 165,854 unvested shares of common stock remain reserved for potential issuance under outstanding awards and may be issued if the vesting terms of such outstanding awards are met. Accordingly, 47,135 shares are available to be issued under the 2019 Plan as of March 31, 2022.

If any outstanding award expires or is canceled, forfeited, or terminated without issuance or vesting of the full number of shares of common stock to which the award related, then such number of shares that expired, or were canceled, forfeited or terminated will be available for future awards under the 2019 Plan. Shares tendered in payment of the option exercise price, shares delivered or withheld by the Company to satisfy any tax withholding obligation, or shares covered by a stock-settled stock appreciation right or other awards that used shares upon the settlement of the award will not again become available for future grants under the 2019 Plan.

Awards may be granted under the 2019 Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines. The Committee (as defined below) will make appropriate adjustments to these limits to prevent dilution or enlargement of the rights of participants under the 2019 Plan.

Administration and Amendment. The 2019 Plan is administered by the Compensation Committee (the "Committee"), or, in the Board’s discretion, by the Board. The Committee will have the authority to, among other things, interpret the 2019 Plan; determine who will be granted awards under the 2019 Plan; prescribe the terms and conditions of each award; interpret, administer, reconcile any inconsistency in, correct any defect in, and supply any omission in the 2019 Plan; and exercise discretion to make any and all other determinations which it determines to be necessary or advisable for the administration of the 2019 Plan.

Available Awards. Awards that may be granted under the 2019 Plan include restricted stock, restricted stock units (RSUs), performance awards, stock options (including both incentive stock options (ISOs) and nonqualified stock options), stock appreciation rights (SARs), and other stock-based awards. The terms of each award will be set forth in a written agreement.

Restricted Stock. A restricted stock award is an award of actual shares of common stock which are subject to certain restrictions for a period of time determined by the Committee. Restricted stock may be held by the Company in escrow or delivered to the participant pending the release of the restrictions. The participant generally has the rights and privileges of a shareholder as to such restricted stock during the restricted period, including the right to vote the restricted stock and the right to receive dividends

Restricted Stock Units. An RSU is an award of hypothetical common stock units having a value equal to the fair market value of an identical number of shares of common stock, which are subject to certain restrictions for a period of time determined by the Committee. No shares of common stock are issued at the time an RSU is granted, and the Company is not required to set aside any funds for the payment of any RSU award. Prior to settlement of an RSU award and the receipt of shares, the participant does not have any rights as a shareholder with respect to such shares. The Committee may grant RSUs with a deferral feature (deferred stock units or DSUs), whereby settlement of the RSU is deferred beyond the vesting date until a future payment date or event set out in the participant’s award agreement. The Committee has the discretion to credit RSUs or DSUs with dividend equivalents.

Performance Share Awards. A performance share award is an award of shares of common stock that are only earned if certain conditions are met. The Committee has the discretion to determine the following: the number of shares of common stock or stock-denominated units subject to a performance share award; the applicable performance period; the conditions that must be satisfied for a participant to earn an award; and the other terms, conditions and restrictions of the award. The number of performance shares earned by a participant depends on the extent to which the performance goals established by the Committee are attained within the applicable performance period. No payout is made with respect to any performance share award except upon written certification by the Committee that the minimum threshold performance goal(s) have been achieved.

Stock Options. A stock option is the right to purchase shares of common stock at a future date at a specified price per share called the exercise price. An option may be either an ISO or a nonqualified stock option. ISOs and nonqualified stock options are taxed differently. Except in the case of options granted pursuant to an assumption or substitution for another option, the exercise price of a stock option may not be less than the fair market value (or in the case of an ISO granted to a ten percent shareholder, 110% of the fair market value) of a share of common stock on the grant date. As of the record date, the closing price of our common stock was $9.05. Full payment of the exercise price must be made at the time of such exercise either in cash or bank check or in another manner approved by the Committee.

Stock Appreciation Rights. A SAR is the right to receive payment of an amount equal to the excess of the fair market value of a share of common stock on the date of exercise of the SAR over the exercise price. The exercise price of a SAR may not be less than the fair market value of a share of common stock on the grant date. SARs may be granted alone ("freestanding rights”) or in tandem with options ("related rights”).

Vesting. The 2019 Plan allows for awards subject to either time-based vesting or performance-based vesting, or both. All awards granted under the 2019 Plan must have a minimum vesting period of at least one year. The Committee has the authority to determine the vesting schedule of each award (subject to the minimum one-year requirement), and to accelerate the vesting and ability to exercise any award. The Company’s practice over the last several years has been to grant restricted stock/unit awards to its executive officers and independent Directors, and stock options to selected non-executive employees. Restricted stock/unit awards to our (i) executive officers have been subject to time-based vesting in equal one-third installments over a three-year period from the grant date and (ii) independent Directors were subject to time-based vesting in equal quarterly installments beginning in the year following the year in which they are granted. However, starting in 2020, the awards to independent Directors are subject to one-year cliff vesting. Stock options granted to our non-executive employees typically vest in equal, one-third tranches over a three-year period. Past vesting requirements may not be indicative of future vesting requirements set by the Committee, which may be less or more onerous than in prior years.

Termination of Service. Unless otherwise set forth in an individual award agreement or in an employment agreement approved by the Committee, any unvested restricted shares, performance shares, RSUs, PSUs and other equity-based awards will immediately be forfeited upon termination of continuous service under the 2019 Plan. Under the Company's restricted

stock and RSU award agreements, if the grantee's continuous service terminates as a result of the grantee's death, Disability (as defined in the 2019 Plan), termination without Cause (as defined in the 2019 Plan and below) or termination for Good Reason (as defined), 100% of the grantee's unvested shares will vest.

Unless otherwise set forth in an individual award agreement or in an employment agreement approved by the Committee, in the event an option holder's continuous service terminates, an option holder may exercise his or her option (to the extent the option holder was entitled to exercise such option at the date of termination) within the earlier of three months following the date of termination or the expiration of the option term. Unless otherwise set forth in an individual award agreement, in the event an option holder's continuous service terminates upon his or her death or Disability (as defined), an option holder or his or her estate may exercise his or her option (to the extent the option holder was entitled to exercise such option at the date of termination), within the earlier of 12 months following the date of termination or the expiration of the option term.

In regard to the definition of Cause under the 2019 Plan, if a participant is under an employment or service agreement with the Company and such agreement provides for a definition of Cause, that definition should be used. If no such agreement exists, or if such agreement does not define Cause, then Cause is defined as (i) the conviction of, or plea of guilty or no contest to, a felony or a crime involving moral turpitude or the commission of any other act involving willful malfeasance or material fiduciary breach with respect to the Company or an Affiliate; (ii) conduct that results in or is reasonably likely to result in harm to the reputation or business of the Company or any of its Affiliates; (iii) gross negligence or willful misconduct with respect to the Company or an Affiliate; or (iv) material violation of state or federal securities laws.

In regard to the definition of Good Reason under the 2019 Plan, if a participant is under an employment or service agreement with the Company and such agreement provides for a definition of Good Reason, that definition should be used. If no such agreement exists, or if such agreement does not define Good Reason, Good Reason is defined as the occurrence of one or more of the following without the participant’s express written consent, which circumstances are not remedied by the Company within thirty (30) days of its receipt of a written notice from the participant describing the applicable circumstances (which notice must be provided by the participant within ninety (90) days of the participant's knowledge of the applicable circumstances): (i) any material, adverse change in the participant's duties, responsibilities, authority, title, status or reporting structure; (ii) a material reduction in the participant’s base salary or bonus opportunity; or (iii) a geographical relocation of the participant's principal office location by more than fifty (50) miles.

Change in Control. A Change in Control is defined as (a) the acquisition by one person or more than one person acting as a group, of Company stock representing more than 50% of the total fair market value or total voting power of the Company’s stock; (b) a merger, consolidation or other reorganization in which the Company is not the surviving entity unless the Company’s shareholders immediately prior to the merger, consolidation or other reorganization maintain at least 50% of the voting power; (c) a majority of the incumbent members of the Board are replaced by Directors whose appointment or election is not endorsed by at least two-thirds of the Board; or (d) the acquisition by one person or more than one person acting as a group, of all or substantially all of the Company’s assets.

Unless otherwise provided in an award agreement, in the event of a participant’s termination of service without Cause or for Good Reason during the 18-month period following a Change in Control, the vesting of all awards will fully accelerate and all outstanding options and SARs will become immediately exercisable as of the date of the participant’s termination of service.

In the case of performance awards, in the event of a participant’s termination of service without Cause or for Good Reason, in either case, within 18 months following a Change in Control, all performance goals or other vesting criteria will be deemed achieved at 100% of target levels and all other terms and conditions will be deemed met as of the date of the participant’s termination of service.

In the event of a Change in Control, the Committee may in its discretion and upon at least 10 days’ advance notice to the affected persons, cancel any outstanding awards and pay to the holders the value of the awards based upon the price per share of common stock received or to be received by other shareholders of the Company in the event. In the case of any option or SAR with an exercise price that equals or exceeds the price paid for a share of common stock in connection with the change in control, the Committee may cancel the option or SAR without the payment of any consideration.

We adopted a Deferred Compensation Plan in December 2015, which permits eligible employees, including our NEOs, and our Directors to annually elect to defer a portion of their salary, commissions, cash bonus, Director fees and/or stock awards they would otherwise have received when earned. Under this plan, participants can defer up to 90% of their salary, commissions, cash bonus, Director fees and stock awards. Cash amounts deferred under the Deferred Compensation Plan are deemed invested in the investment funds selected by the participant with similar options as available under the Company’s 401(k) Plan. We have option to contribute but do not currently contribute to the Deferred Compensation Plan on behalf of its participants or match the deferrals made by participants.

At the time of deferral, a participant must indicate whether he or she wishes to receive the amount deferred while in-service or upon separation of service. In either case, the payment will be in either a lump sum or in substantially equal annual installments. In-service installments cannot exceed five years, while installments elected to start upon separation of service cannot exceed ten years. If separation is due to a disability or a change in control, deferrals will be paid similar to deferrals paid upon separation of service, while deferrals related to death will be paid in a lump sum to the participant’s beneficiary. If a participant experiences an unforeseeable emergency during the deferral period, the participant may petition to receive a partial or full payout from the Deferred Compensation Plan. All distributions are made in cash, except for deferred stock awards which are settled in Company stock.

We use a combination of cash and equity-based incentive compensation to attract and retain qualified candidates to serve on our Board of Directors. In setting compensation for our Directors, we consider the substantial amount of time that Directors expend in fulfilling their duties to us and our shareholders, as well as the skill-sets required to fulfill these duties.

(1) Our non-employee Directors are paid a quarterly cash fee. The cash fee payable to our non-employee Directors was $13,750 per quarter for 2021 and $12,500 per quarter for 2020 and 2019. In addition, the Chairman of the Audit Committee, David L. Bradshaw, the Chairman of the Compensation Committee, Leslie A. Beyer, the Chairman of the ESG and Personnel Development Committee, Nigel J. Jenvey and the Chairman of the Nominating Committee and Lead Director, John Chisholm, were entitled to an additional quarterly cash fee in the amount of $3,750.

(2) On March 18, 2021, each of our non-employee Directors were granted 5,612 restricted shares at an issue price of $8.91 per share; on April 1, 2021, Mr. Jenvey was granted 5,291 restricted shares at an issue price of $9.45; on April 28, 2020, each of our non-employee Directors were granted 4,432 restricted shares at an issue price of $5.64 per share; on October 15, 2020, Ms. Beyer was granted 1,324 restricted shares at an issue price of $9.44; and on March 29, 2019, each of our non-employee Directors were granted 5,784 restricted shares/units at an issue price of $17.29 per share.

We pay our non-employee Directors a quarterly cash fee for their attendance at each meeting of our Board of Directors. The cash fee payable to our non-employee Directors for 2021 was $13,750 per quarter and $12,500 per quarter for 2020 and 2019. In addition, the Chairmen of the Audit, Compensation, ESG and Nominating Committees were entitled to an additional quarterly cash fee in the amount of $3,750.

Our compensation policy for independent Directors is to grant an annual award of restricted shares based upon a review of equity award values paid by other public companies in the Company's peer group and the Company's market and financial performance in comparison to such peer group companies. For 2021, based upon the Company's performance compared to its peer group, the Compensation Committee recommended and the Board approved an equity award value of

approximately $100,000 in restricted stock. However, because of the depressed nature of the energy industry and dilutive nature of the Company's stock at then current market prices, the Board determined to modify the award into a 50/50 split of stock and cash. In connection therewith, on March 18, 2021, each of our three independent Directors were granted the following:

On April 1, 2021, William F. Hughes retired and resigned from his position as a member of the Board of Directors of the Company. In recognition of Mr. Hughes’ longstanding service, the Compensation Committee voted to accelerate the vesting of the following unvested shares, free of any further restrictions:

All Directors are reimbursed for their expenses incurred in connection with attending meetings. We provide liability insurance for our Directors and officers. The cost of this coverage for 2021 was $221,723. We do not offer non-employee Directors travel accident insurance, life insurance, or a pension or retirement plan.

On October 23, 2013, Stephen C. Taylor entered into a new employment agreement with us (the “Employment Agreement”), pursuant to which Mr. Taylor continues his employment as our President and Chief Executive Officer. The new Employment Agreement became effective on the same date and Mr. Taylor’s previous employment agreement with us, which was set to expire on October 25, 2013, was terminated in connection therewith.

On April 24, 2015, we entered into an amendment with Mr. Taylor to his Employment Agreement pursuant to which the "modified single trigger" change of control provision was changed to a "double trigger" change of control. Under the "modified single trigger provision", Mr. Taylor could voluntarily terminate the Employment Agreement for any reason and collect severance benefits. Under the new "double trigger" change of control provision, a change of control must occur followed by the Company or its successor terminating Mr. Taylor's employment other than for cause, death, or disability, or by Mr. Taylor terminating his employment for Good Reason. We discuss the definitions of "Change of Control" and "Good Reason" below, along with Mr. Taylor's severance benefits in connection with these events.

The term of the Employment Agreement is for three years but the agreement contains an “evergreen” feature whereby the agreement is automatically extended on a monthly basis on the last day of each month so that the term of the agreement will always be three years unless written notice of nonrenewal is given by the Company. If a notice of nonrenewal is given, the term of employment then ends three years from the date of that written notice of nonrenewal unless terminated earlier as described below. The Employment Agreement provides for Mr. Taylor to receive a base salary, potential cash bonus, equity compensation, and certain other benefits, which are summarized below.

Bonus. Mr. Taylor will continue to be eligible for an annual cash bonus under the Company’s current Annual Incentive Bonus Plan. Mr. Taylor’s annual bonus opportunity payable upon achievement of “target” levels shall be at least ninety percent (90%) of Base Salary for 2013 and at least one hundred percent (100%) thereafter. The performance metrics, weighting and thresholds for each annual bonus opportunity will be determined by the Company’s Board of Directors or Compensation Committee in good faith following consultation with Mr. Taylor.

Annual Equity Compensation. Mr. Taylor is eligible for annual grants of equity-based incentive awards under the Company’s equity compensation plans. While the agreement provides an annual equity award grant to Mr. Taylor with an aggregate minimum value equal to 175% of his Base Salary, subject to one-year vesting terms, Mr. Taylor has waived the 175% and one-year vesting requirement for the past four years in order to enable the Compensation Committee to make discretionary and performance based awards with a three-year vesting term (subject to customary acceleration) in keeping with current public company pay practices.

Benefits. The Company will provide Mr. Taylor such retirement, and other benefits as are customarily provided to similarly situated executives of the Company, including paid vacation, coverage under the Company’s medical, life, disability and other insurance plans, and reimbursement for all reasonable business expenses in accordance with the Company’s expense reimbursement policy.

(A) If (i) the Company terminates Mr. Taylor's agreement without Cause (ii) Mr. Taylor terminates the agreement for Good Reason or due to a Change of Control event (as defined below) followed by the Company or its successor terminating Mr. Taylor's agreement without cause or Mr. Taylor terminating the agreement for Good Reason or (iii) Mr. Taylor's employment is terminated due to death or disability, then he will receive (a) a lump sum payment equal to 300% of Base Salary and Annual Bonus; (b) vesting of all unvested equity awards or other long-term incentive compensation; (c) continuation of health insurance benefits and payment of any life insurance premiums for a period of 36 months after termination; and (d) receipt of any other vested benefits which had not yet been paid prior to the date of termination.

(C) If Mr. Taylor retires in compliance with the Company's retirement policy, then he will be entitled to (i) any unpaid compensation earned through the date of retirement; (ii) vesting of all unvested equity awards or other long-term incentive compensation; and (iii) receipt of any other vested benefits which had not yet been paid prior to the date of termination.

(A) his employment is automatically terminated upon the expiration of the remaining three year term, Mr. Taylor shall be entitled to (i) any unpaid compensation earned through the date of retirement; (ii) vesting of all unvested equity awards or other long-term incentive compensation; and (iii) receipt of any other vested benefits which had not yet been paid prior to the date of; or

(B) his employment is terminated prior to the expiration of the remaining three year term, unless said termination is due to Cause, voluntary resignation or retirement, then Mr. Taylor shall be entitled to (i) lump sum payment of his Base Salary at the time of termination for the remainder of the three year term of the agreement; (ii) a lump sum cash payment equal to 100% of the Annual Bonus for each full year (if any) remaining in the three year term, plus a pro rata portion of such Annual Bonus for any partial remaining year in the three year term; (iii) vesting of all unvested equity awards or other long-term incentive compensation; (iv) continuation of health insurance benefits and payment of any life insurance premiums for the remainder of the three year term of the agreement; and (v) receipt of any other vested benefits which had not yet been paid prior to the date of termination.

Under the Employment Agreement, a "Change of Control" event includes (i) the acquisition by a person, entity or group of related persons or entities of more than 30% of the total voting power in the Company (excluding sales to underwriters in a public offering); (ii) consummation of the sale of 50% or more of the Company's assets; (iii) consummation of a merger or consolidation of the Company with or into an entity unless the voting securities of the Company immediately prior to the merger or consolidation continue to represent more the 70% of the voting power of the surviving entity after the merger or consolidation; and (iv) replacement of at least a majority of the incumbent members of the Company's Board of Directors, excluding Directors whose election to the Board was approved by at least a majority of the then incumbent Directors, subject to further limited exceptions as set forth in the "Change of Control" definition in Employment Agreement.

Under the Employment Agreement, a "Good Reason" event includes (i) a material diminution of Mr. Taylor's duties, control, authority or status or position or a requirement that the Executive report to a corporate officer or employee instead of reporting directly to the Board of Directors; (ii) a material reduction in Mr. Taylor's compensation; (iii) a material breach by the Company of the Employment Agreement; or (iv) a relocation of more than 50 miles of Mr. Taylor's principal office with the

Company or its successor. And in connection with a termination due to Change of Control, the following provisions also constitute “Good Reason” events: (i) a material diminution of Mr. Taylor's duties, control, authority or status or position or a requirement that Mr. Taylor report to a corporate officer or employee instead of reporting directly to the Company's or successor’s Board of Directors depending on its composition after the change in control; (ii) the failure of the Company or successor to continue in effect any plan in which Mr. Taylor participates immediately prior to the Change in Control which is material to the Executive’s total compensation, unless an equitable arrangement has been made with respect to any such plan on a basis not less favorable, both in terms of the amount or timing of payment of benefits provided; and (iii) a material breach by the Company or its successor of the Employment Agreement or any other material agreement between Mr. Taylor and the Company or its successor.

Non-Competition and Non-Solicitation. In connection with the payment of the severance benefits described above, for a period of two years following Mr. Taylor’s separation from the Company, he may not compete with the Company in any geographic area within a 100 mile radius of a Company owned or leased facility which is Company staffed and actively engaging in business on behalf of the Company.

This limitation on liability may have the effect of reducing the likelihood of derivative litigation against Directors and Officers, and may discourage or deter shareholders or management from bringing a lawsuit against Directors and Officers for breach of their duty of care even though such an action, if successful, might otherwise have benefited our shareholders and us.

Our Articles of Incorporation and bylaws provide certain indemnification privileges to our Directors, employees, agents and officers against liabilities incurred in legal proceedings. Also, our Directors, employees, agents or officers who are successful, on the merits or otherwise, in defense of any proceeding to which he or she was a party, are entitled to receive indemnification against expenses, including attorneys’ fees, incurred in connection with the proceeding.

We are not aware of any pending litigation or proceeding involving any of our Directors, officers, employees or agents as to which indemnification is being or may be sought, and we are not aware of any other pending or threatened litigation that may result in claims for indemnification by any of our Directors, officers, employees or agents.

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our Directors, officers and persons who beneficially own more than 10% of our Common Stock to file certain reports of beneficial ownership with the Securities and Exchange Commission. These reports show the Directors’, officers’ and greater than 10% shareholders' ownership and the changes in ownership of our common stock and other equity securities. The SEC regulations also require that a copy of all such Section 16(a) forms filed must be furnished to us by the person or entity filing the report. To the Company’s knowledge, during the fiscal year ended December 31, 2021, all reports required to be filed pursuant to Section 16(a) were filed on a timely basis.

On March 7, 2007, we adopted a written policy for the review, approval or ratification of related party transactions. All of our officers, Directors and employees are subject to the policy. Under this policy, the Audit Committee will review all related party transactions for potential conflict of interest situations. Generally, our policy defines a “related party transaction” as a transaction in which we are a participant and in which a related party has an interest. A “related party” is:

Before entering into a related party transaction, the related party or our department responsible for the potential transaction must notify the CEO or the Audit Committee of the facts and circumstances of the proposed transaction. If the amount involved is equal to or less than $100,000, the proposed transaction will be submitted to the CEO. If the amount involved exceeds $100,000, the proposed transaction will be submitted to the Audit Committee. Matters to be submitted will include:

The CEO or the Audit Committee, as applicable, will then consider all of the relevant facts and circumstances available, including the matters described above and, if applicable, the impact on a Director’s independence. Neither the CEO nor any member of the Audit Committee is permitted to participate in any review, consideration or approval of any related party transaction if such person or any of his or her immediate family members is the related party. After review, the CEO or the Audit Committee, as applicable, may approve, modify or disapprove the proposed transaction. Only those related party transactions that are in, or are not inconsistent with, our best interests and that of our shareholders will be approved.

If one of our officers or Directors becomes aware of a related party transaction that has not been previously approved or ratified by the CEO or the Audit Committee, if the transaction is pending or ongoing, the transaction must be submitted, based on the amount involved, to either the CEO or the Audit Committee to consider the matters described above. Based on the conclusions reached, the CEO or the Audit Committee, as applicable, will evaluate all options, including ratification, amendment or termination of the related party transaction. If the transaction is completed, the CEO or the Audit Committee will (i) evaluate the transaction, taking into account the same factors as described above, to determine if rescission of the transaction or any disciplinary action is appropriate; and (ii) will request that we evaluate our controls and procedures to determine the reason the transaction was not submitted to the CEO or the Audit Committee for prior approval, and whether any changes to the procedures are recommended.

The aggregate fees billed for professional services rendered by Moss Adams for the audit of our consolidated financial statements for the years ended December 31, 2021 and 2020, and the review of the financial statements on Forms 10-Q for the quarters in such years were approximately $242,250 and $257,575, respectively.

As of the date of this proxy statement, our Audit Committee has not established general pre-approval policies and as of December 31, 2021, our Audit Committee had not established pre-approval policies and procedures for the engagement of our principal accountant to render audit or non-audit services. However, in accordance with Section 10A(i) of the Exchange Act, our Audit Committee, as a whole, approves the engagement of our principal accountant prior to the accountant rendering audit or non-audit services.
