ANNUAL REPORT 
2015 

Against the backdrop of one of the worst downturns in our industry, Natural Gas Services Group was 
able  to  deliver  exceptional  results.  Whether  measured  against  our  peers  and  competitors  or  the 
industry as a whole, very few companies delivered the financial results we did.  

In 2015, NGS total revenues were $95.9 million, a decrease of only 1% from 2014; a record year for 
company revenues. Rental revenues did exhibit a 3% overall decline, but we were able to increase our 
compressor fabrication revenues enough to offset those. Positively, we moved quickly to control our 
expenses and deliver some of the highest rental gross margins we have experienced in the past few 
years. Gross margins averaged 62% in 2015 as compared to 60% in 2014.  

NGS began pulling back on our rental fabrication activity in the fourth quarter of 2014 which, upon 
reflection,  was  the  same  quarter  that  the  US  rig  count  peaked.  We  experienced  the  same 
phenomena  in  2008  when  we  started  to  decrease  our  fabrication  activity in  the  3rd  quarter;  again, 
the peak rig activity of the last cycle. Our ability to proactively adjust our levels of activity is critically 
important during these times of market dislocation. Capital expenditures in 2015 were $12.5 million, 
a 77% reduction from 2014.

President & Chief Executive Officer, 
Natural Gas Services Group, Inc. 

With shop and field level expenses under control, NGS also continued to hold our Sales, General and Administrative overhead expenses 
to the lowest level in the business, an average of 11% of revenue.  

During the year we made the decision to retire some of our older, small horsepower, low-pressure compressor units that had been used 
primarily in dry gas service. Since the natural gas price collapse in 2009 these units had not been fully utilized and we did not forecast any 
significant  future  use  for  the  equipment.  The  retirement  idled  9%  of  our  unit  fleet  count,  but  only  2%  of  the  net  book  value.  The 
equipment is being salvaged and we will be able to re-use a significant portion of it. 

Not accounting for the effect of the equipment retirements, net income for the year was $13.2 million and EBITDA (a non-GAAP measure 
commonly  used  as  a  proxy  for  operating  cash  flow)  was  $42.4  million.  This  equates  to  44%  of  revenue,  a  uniquely  high  level  of  cash 
generation. Along with this cash generation and the decrease in our capital expenses, NGS was able to increase our cash balance to $35.5 
million while maintaining our debt level at less than $500,000. 

NGS’s  relative  common  stock  performance  was  gratifying. Our  common  stock  decreased  3%  during  the  calendar year  2015,  while  our 
public peers were down 43.5%, the OSX index (oil service sector) was off 25.2%, the U.S land rig count decreased 61.5% and the price of 
WTI crude oil fell 30.5%. 

Although  cost-cutting  was  a  particular  focus  in  2015,  NGS  also  took  some  aggressive  actions  to  better  position  us  when  the  market 
improves. Our new, larger horsepower compressor package was introduced (see cover) with the initial units set in the Rocky Mountain 
area. On the other end of the spectrum, we developed and introduced a line of smaller horsepower Vapor Recovery Units (VRUs). This 
type of equipment is being deployed on a more regular basis due to environmental regulations and we anticipate the start of a constantly 
growing market. 

Commenting on 2016, the year started out with crude oil prices continuing their decline and recently bottoming in February in the mid-
$20  per  barrel  range.  The  industry  and  our  customers  reacted  and  NGS’s  equipment  utilization  and  pricing  continued  to  be  under 
pressure. Although the price of oil has recovered somewhat, the drilling rig count continued to decline and there remains an extremely 
cautionary tone in the industry. We are starting to see some positive supply and demand indicators, but volatility will continue and any 
resumption  in  activity  will  take  a  few  quarters  to  play  out.  I  anticipate  that  2016  will  be  the  toughest  year  so  far,  but  NGS  is  well-
positioned to react and emerge as one of the strongest players in the market. 

I want to thank our shareholders, employees and board members for their interest, work and support on behalf of NGSG this past year. 
Although  down  turning  markets  are  unpredictable  in  their  breadth  and  depth,  I  am  confident  that  NGSG  will  emerge  in  a  preferred 
position. 

As always, you are invited to NGSG’s annual meeting in Midland, Texas on June 16, 2016, beginning at 8:30 am CDT. The meeting will be 
held in the Board Room of the Midland Petroleum Club at 501 West Wall Street.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS
AND THE MEETING

Q:  Why am I receiving these materials?

A: Our Board is providing these proxy materials to you in connection with our 2016 Annual Meeting of Shareholders, which will 
take place on Thursday, June 16, 2016. As a shareholder on the record date for the meeting, you are invited to attend the meeting. 
We also encourage you to vote on the matters described in this proxy statement.

Q:  What information is contained in these materials?

A: This proxy statement includes information about the nominee for director and the other matters to be voted on at the meeting. 
The proxy statement also includes information about the voting process and requirements, the compensation of directors and some 
of our executive officers, and certain other required information.

Q: What can I vote on at the meeting?

A: There are five matters to be voted on at the meeting:

1.  To elect one Director to serve until the Annual Meeting of Shareholders to be held in 2019, or until his successor 

is elected and qualified;

2.  To consider an advisory vote on the Company's compensation programs for its named executive officers;

3.  To approve the amendment and restatement of the Company's 1998 Stock Option Plan for another ten year term 
and increase the number of shares reserved for issuance under the plan by 250,000 shares of common stock;

4.  To ratify the appointment of BDO USA, LLP as the Company’s independent registered public accounting firm 

for 2016;

5. To consider an amendment to the Company’s Bylaws to implement a majority voting standard in uncontested 

election of Directors; and

6. To transact such other business as may properly be presented at the meeting, or at any adjournment(s) of the 

meeting.

Q:  How does the Board recommend that I vote on each of the matters?

A: Our Board recommends that you vote FOR the director nominee, FOR the amendment and restatement of the 1998 Stock 
Option Plan, FOR the ratification of the appointment of BDO USA, LLP as our independent registered public accounting firm 
for 2016, and FOR the amendment to our Bylaws to implement majority voting in the uncontested election of Directors.  With 
respect to Proposal 2, the Board of Directors recommends that you vote FOR approval, on an advisory basis, of the compensation 
programs of our named executive officers as disclosed in the Compensation Discussion and Analysis, the compensation tables, 
and the related disclosure contained in the proxy statement set forth under the caption “Executive Compensation” of this proxy 
statement.  

Q:  Why did I receive a two-page notice in the mail regarding the Internet availability of proxy materials this year instead 
of a full set of proxy materials?

A: We are taking advantage of SEC rules that allow us to deliver proxy materials to our shareholders on the Internet. Under these 
rules, we are sending most of our shareholders a two-page notice regarding the Internet availability of proxy materials instead of 
a full set of proxy materials. If you receive this two-page notice, you will not receive printed copies of the proxy materials unless 
you specifically request them. Instead, this notice tells you how to access and review on the Internet all of the important information 
contained in the proxy materials. This notice also tells you how to submit your proxy card on the Internet and how to request to 
receive a printed copy of our proxy materials. Shareholders may also request to receive proxy materials in printed form by mail 
or electronically by email on an ongoing basis.

Q:  Can I receive next year’s proxy materials by email?

A: Yes. All shareholders who have active email accounts and Internet access may sign up for email delivery of shareholder materials. 
To sign up, go to www.proxyvote.com and click on “Electronic Enrollment.” If you have multiple registered or beneficial accounts, 
you need to enroll for each account. If you elect to receive proxy materials by email, we will not mail you any proxy-related 
materials next year. Your enrollment in the email program will remain in effect as long as your account remains active or until 
you cancel it.

Q:  Who is entitled to vote at our annual meeting of shareholders?

A: Holders of our outstanding common stock on April 18, 2016, are entitled to one vote per share on each of the items being voted 
on at the meeting. We refer to this date as the Record Date. On the Record Date, we had 12,864,226 shares of common stock 
outstanding.  We have no other classes of stock outstanding.

Q:  What shares can I vote?

A: You can vote all shares you owned on the Record Date. These shares include (1) shares held directly in your name as the 
shareholder of record and (2) shares held for you as the beneficial owner through a stockbroker, bank or other nominee.

Q:  What is the difference between holding shares as a shareholder of record and as a beneficial owner?

A: Most of our shareholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. 
There are some important distinctions between shares held of record and those owned beneficially.

Shareholder of Record

If your shares are registered in your name with our transfer agent, Computershare, you are the shareholder of record for those 
shares and are receiving proxy-related materials directly from us. As the shareholder of record, you have the right to grant your 
voting proxy directly to us or to vote in person at the meeting.

Beneficial Owner

If your shares are held in a stock brokerage account, by a bank or other nominee (commonly referred to as being held in “street 
name”) you are the beneficial owner of those shares. Your broker, bank or nominee is the shareholder of record and therefore has 
forwarded proxy-related materials to you as beneficial owner. As the beneficial owner, you have the right to direct your broker, 
bank or other nominee how to vote your shares and are also invited to attend the meeting. However, since you are not the shareholder 
of record, you may not vote your shares in person at the meeting unless you obtain a signed proxy from your broker, bank or 
nominee giving you the right to vote the shares.

Q:  How do I vote if I am a shareholder of record (as described in the question and answer above)?

A: You can vote on the Internet or by telephone by following the instructions you received in the mail or by email. If you received 
a full printed set of our proxy materials in the mail, you can also vote by mail by signing and returning the proxy card provided 
with those materials. Finally, you can vote in person at the meeting.

Q:  How do I vote if I am a beneficial owner (as described in the question and answer above)?

A: You can vote on the Internet or by telephone by following the instructions you received in the mail or by email. If you received 
a full printed set of our proxy materials in the mail, you can also vote by mail. You can vote in person at the meeting only if you 
obtain a signed proxy from your broker, bank or nominee giving you this right.

Q:  Can I change my vote or revoke my proxy?

A: Yes. You can change your vote or revoke your proxy at any time before the final vote at the meeting. You can do this by casting 
a later proxy through any of the available methods described in the questions and answers above. If you are a shareholder of record, 
you can also revoke your proxy by delivering a written notice of your revocation to our Corporate Secretary at our principal 
executive office at 508 West Wall Street, Suite 550, Midland, Texas 79701. If you are a beneficial owner, you can revoke your 
proxy by following the instructions sent to you by your broker, bank or other nominee.

2

Q:  What does it mean if I get more than one set of proxy-related materials?

A: It means you hold shares registered in more than one account. Follow the instructions in each set of proxy-related materials to 
ensure that all of your shares are voted.

Q:  What is the quorum requirement for the meeting?

A: For a “quorum” to exist at the meeting, shareholders holding a majority of the votes entitled to be cast by the shareholders 
entitled to vote must be present in person or represented by proxy at the meeting. There must be a quorum for any action to be 
taken at the meeting (other than adjournment or postponement of the meeting). If you submit a properly completed proxy, even 
if you abstain from voting, then your shares will be counted for purposes of determining the presence of a quorum.

If a broker indicates on a proxy that it lacks discretionary authority as to certain shares to vote on a particular matter, commonly 
referred to as “broker non-votes,” those shares will still be counted for purposes of determining the presence of a quorum at the 
meeting.  Please see the next question and answer for further information about "broker non-votes."

Q:  What are broker non-votes and how are broker non-votes and abstentions counted?

A: If you are a beneficial owner and hold your shares in street name and do not provide your broker or other nominee with voting 
instructions, the broker, bank, or other nominee will determine if it has the discretionary authority to vote on the particular matter. 
The New York Stock Exchange permits brokers to vote their customers' shares on routine matters when the brokers have not 
received voting instructions from the customers. The ratification of independent public accountants is an example of a routine 
matter on which brokers may vote. Brokers may not vote their customers' shares on non-routine matters unless they have received 
instructions from the customers. Non-voted shares on non-routine matters are referred to as broker non-votes. The ratification of 
the appointment of BDO USA, LLP as our independent public accountants for 2016 (Proposal 4) is a matter considered "routine" 
under application rules. The election of one director (Proposal 1), the advisory vote to approve the named executive officers 
compensation programs (Proposal 2), the approval of the amendment and restatement of the 1998 Stock Option Plan (Proposal 
3) and the amendment to the Company’s Bylaws to implement a majority voting standard in uncontested election of 
Directors (Proposal 5) are matters considered "non-routine" under applicable rules. A broker or other nominee cannot vote 
without instructions on non-routine matters. Abstentions and broker non-votes will have no effect on Proposal 1, as the election 
of a  Director is determined by counting the votes actually cast where abstentions and broker non-votes are not treated as votes 
cast. With respect to the advisory vote to approve the named executive officers compensation programs (Proposal 2), the approval 
of the 1998 Stock Option Plan amendment and restatement (Proposal 3) and the amendment to the Bylaws (Proposal 5) where the 
vote required is a majority of votes present and entitled to vote, abstentions will be equivalent to a vote cast against the proposals 
and broker non-votes will have no effect.

Q:  What is the voting requirement to approve each of the matters?

A: Directors are elected by a plurality of the votes cast at the Annual Meeting. This means that the nominee for election as Director 
who receives the greatest number of votes cast in favor of his or her election will be elected to the Board of Directors. The  advisory 
vote on the compensation programs of our named executive officers, the amendment and restatement of the 1998 Stock Option 
Plan, ratification of the appointment of BDO USA, LLP as the Company’s independent registered public accounting firm, and the 
amendment to the Bylaws to implement a majority voting standard in the uncontested election of Directors are approved if the 
votes cast in favor of the matter exceed the votes cast against the matter. If you are a beneficial owner and do not provide the 
shareholder of record with voting instructions, your shares may constitute broker non-votes for certain matters (as described in 
the question and answer immediately above). In tabulating the voting result for a proposal, shares that constitute broker non-votes 
are not considered as being entitled to vote on that proposal.

Q:  How can I vote on each of the matters and how will the votes be counted?

A: In the election of directors, you may vote “FOR,” “AGAINST,” or “ABSTAIN” with respect to the nominee. If you elect to 
abstain from the election of directors, the abstention will not have any effect on the election of directors. In tabulating the voting 
results for the election of directors, only “FOR” and “AGAINST” votes are counted.

For the (i) advisory vote on compensation of our named executive officers, (ii) approval of the amendment and restatement of the 
1998 Stock Option Plan, (iii) ratification of the appointment of BDO USA, LLP as our independent auditors and (iv) the amendment 
to the Bylaws to implement a majority voting standard in the uncontested election of Directors, you may vote “FOR,” “AGAINST,” 

3

or “ABSTAIN” with respect to these four proposals. If you elect to abstain from voting on any of these proposals, the abstention 
will have the same effect as an “AGAINST” vote with respect to such proposal.

If you sign and return your proxy card or voting instruction form without giving specific voting instructions, your shares will be 
voted as recommended by our Board. If you are a beneficial holder and do not return a voting instruction form, your broker may 
only vote on the ratification of the appointment of BDO USA, LLP (Proposal 4).

Q:  Who will count the votes?

A: Broadridge, an international investor relations company, is assisting us with the voting of proxies for our meeting. Prior to the 
meeting, Broadridge will provide us with a tabulation of the votes cast prior to the meeting. We believe that Broadridge will use 
procedures that are consistent with Colorado law concerning the voting of shares, the determination of the presence of a quorum 
and the determination of the outcome of each matter submitted for a vote. In addition, we will appoint a voting inspector at the 
meeting to count and tabulate any votes cast at the meeting.

Q:  Who may attend the meeting?

A: All shareholders as of the Record Date may attend. Please bring to the meeting:

•  proof of ownership such as: a copy of your proxy or voting instruction card; the two-page notice regarding the internet 
availability of proxy materials you received in the mail; or a copy of a brokerage or bank statement showing your 
share ownership as of the Record Date; and 

•  proof of identification such as a valid driver’s license or passport.

Q:  How will voting on any other business be conducted?

A: We do not expect any matters to be presented for a vote at the meeting other than the five matters described in this proxy 
statement. If you grant a proxy, either of the officers named as proxy holders, Stephen C. Taylor and G. Larry Lawrence, or their 
nominees or substitutes, will have the discretion to vote your shares on any additional matters that are properly presented for a 
vote at the meeting and at any adjournment or postponement that may take place. If, for any unforeseen reason, our nominee is 
not available as a candidate for director, the persons named as the proxy holder will vote your proxy for another candidate or other 
candidates nominated by our Board.

Q:  May I propose actions for consideration at next year’s meeting of shareholders?

A: Yes. For your proposal to be considered for inclusion in our proxy statement for next year’s meeting, we must receive your 
written proposal no later than December 19, 2016. If we change the date of next year’s meeting by more than 30 days from the 
date of this year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy materials. You 
should also be aware that your proposal must comply with SEC regulations regarding shareholder proposals.

Similarly, for you to raise a proposal (including a director nomination) from the floor at next year’s meeting, we must receive a 
written notice of the proposal no later than March 9, 2017.  If we change the date of next year’s meeting by more than 30 days 
from the date of this year’s meeting, then we must receive your written proposal at least 150 days before the date of next year’s 
meeting for the proposal to be timely.

Q:  Who is paying for this proxy solicitation?

A: We will pay the cost of soliciting the proxies. In addition, our officers, directors and employees may solicit proxies or votes in 
person, by telephone or by email. These people will not be paid any additional compensation for these activities. We will send 
copies of proxy-related materials or additional solicitation materials to brokers, fiduciaries and custodians who will forward these 
materials to the beneficial owners of our shares. On request, we will reimburse brokers and other persons representing beneficial 
owners of shares for their reasonable expenses in forwarding these materials to beneficial owners.

HOUSEHOLDING OF PROXY MATERIALS

In an effort to reduce printing costs and postage fees, we have adopted a practice called “householding.” Under this 
practice, shareholders who have the same address and last name and do not participate in email delivery of proxy-related materials 
will receive only one set of our proxy statement, annual report or notice of internet availability of proxy-related materials unless 
one or more of these people notifies us that he or she wishes to continue to receive individual copies.

If you share an address with another shareholder and receive only one set of proxy-related materials and would like to 
request a separate copy for this year’s annual meeting or for any future meetings, please: (1) call our Investor Relations contact 
at (432) 262-2700; (2) send an email message to alicia.dada@ngsgi.com; or (3) mail your request to Natural Gas Services Group, 
Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701, Attn: Investor Relations. Similarly, you may also contact us through 
any of these methods if you receive multiple copies of the materials and would prefer to receive a single copy in the future.

PROPOSAL 1 - ELECTION OF DIRECTORS

Our Board of Directors is divided into three classes (commonly known as a “staggered” Board), each class to be as nearly 
equal in number as possible.  At each annual meeting of shareholders, members of one of the classes, on a rotating basis, are 
elected for a three-year term.  The authorized number of Directors is currently set at nine. We currently have five directors serving 
on our Board.  Our Board of Directors may fill the vacancies if a qualified candidate is vetted.  The following table sets forth, by 
class, the members of our Board of Directors as of the date of this proxy statement:

Terms Expiring at the
2016 Annual Meeting
John W. Chisholm

Terms Expiring at the
2017 Annual Meeting
Charles G. Curtis

 Stephen C. Taylor

Terms Expiring at the
2018 Annual Meeting
David L. Bradshaw

William F. Hughes

Shareholders will be electing one Director at the meeting.  The Board is recommending Mr. John Chisholm for re-election

             THE BOARD OF DIRECTORS AND ITS COMMITTEES

Natural Gas Services Group’s Board of Directors held four meetings in 2015.  Each Director attended at least 75% of the 
total number of Board meetings held while such person was a Director.  Each Director also attended at least 75% of all of the 
meetings held by all committees of the Board of Directors for which he served (during the periods that he served).  The Board of 
Directors acts from time to time by unanimous written consent in lieu of holding a meeting.

Our  non-management  directors  hold  regularly  scheduled  executive  sessions  in  which  those  directors  meet  without 
management participation.  The Chairman of the Governance and Personnel Development Committee has presided over these 
sessions. In April 2016, the board established a Lead Director role, and assigned those duties to the Lead Director. Charles G. 
Curtis is currently the Lead Director.

We typically schedule a Board meeting in conjunction with our annual meeting of shareholders.  Although we do not 
have a formal policy on the matter, we expect our Directors to attend each annual meeting, absent a valid reason, such as illness 
or an unavoidable schedule conflict.  Last year, all of the individuals then serving as Directors attended our 2015 Annual Meeting 
of Shareholders.

To assist it in carrying out its duties, the Board has delegated certain authority to four separately designated standing 

committees. These committees are described below.

Audit Committee

The primary functions of our Audit Committee include:

•  assisting the Board in fulfilling its oversight responsibilities as they relate to our accounting policies, internal 

controls, financial reporting practices and legal and regulatory compliance;

•  hiring our independent registered public accounting firm;

•  monitoring the independence and performance of our independent registered public accounting firm;

•  maintaining,  through  regularly  scheduled  meetings,  a  line  of  communication  between  the  Board,  our 

financial management and independent registered public accounting firm; and

•  overseeing compliance with our policies for conducting business, including ethical business standards.

The members of the Audit Committee are David L. Bradshaw (Chairman), Charles G. Curtis, and William F. Hughes, Jr. 
Our  common stock  is  listed for trading on the New York Stock  Exchange, or  “NYSE”. Under rules of  the NYSE, the Audit 
Committee is to be comprised of three or more Directors, each of whom must be independent.  Our Board has determined that all 
of the members of the Audit Committee are independent, as defined under the applicable NYSE rules and listing standards.  In 
addition, our Board of Directors has determined that David L. Bradshaw is qualified as an “audit committee financial expert” as 
that term is defined in the rules of the Securities and Exchange Commission.  The Audit Committee met nine times during the last 
fiscal year. The audit committee has also received from, and discussed with, BDO the matters required to be discussed by Public 
Accounting Oversight Board Auditing Standard No. 16. (Communications with Audit Committees).

Any shareholder may obtain free of charge a printed copy of our Audit Committee Charter by sending a written request 
to Investor Relations, Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701.  You can also

website at www.ngsgi.com.

Compensation Committee

The functions of our Compensation Committee include:

•  assisting the Board in overseeing the management of our human resources;

•  evaluating our Chief Executive Officer’s performance and compensation;

•  formulating and administering our overall compensation principles and plans; and

•  evaluating management.

The Compensation Committee’s policy is to offer the executive officers competitive compensation packages that will 
permit us to attract and retain individuals with superior abilities and to motivate and reward such individuals in an appropriate 
fashion in the long-term interests of Natural Gas Services Group, Inc., and its shareholders.  Currently, executive compensation 
is comprised of salary and cash bonuses and awards of long-term incentive opportunities in the form of restricted stock awards 
under the 2009 Restricted Stock/Unit Plan.

The members of the Compensation Committee are William F. Hughes, Jr. (Chairman), John W. Chisholm and David L.  
Bradshaw. Our Board has determined that all of the members of the Compensation Committee are independent, as defined under 
the applicable NYSE rules and listing standards.  During the last fiscal year there were six meetings of the Compensation Committee.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee members are not officers or employees of our company, and there is not, nor was there 
during fiscal 2015, 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 of Directors or our Compensation 
Committee).

Any shareholder may obtain free of charge a printed copy of our Compensation Committee Charter by sending a written 
request to Investor Relations, Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701.  You can 
also view and print a copy of our Compensation Committee Charter by clicking on the “Governance” tab at the Investor Relations 
page of our website at www.ngsgi.com.

Governance and Personnel Development Committee

Our Governance and Personnel Development Committee primarily focuses on:

•  generally overseeing the governance of the Board and its committees;

•  interpreting  the  Governance  Guidelines,  the  Code  of  Business  Conduct  and  Ethics  and  other  similar 

governance documents adopted by the Board; and

•  overseeing the evaluation of the Board and its committees.

The members of the Governance and Personnel Development Committee are Charles G. Curtis (Chairman), John W. 
Chisholm  and  William  F.  Hughes,  Jr.  Our  Board  has  determined  that  each  of  the  Governance  and  Personnel  Development 
Committee members is independent, as defined under the applicable NYSE rules and listing standards.  During the last fiscal year 
there were four meetings of the Governance and Personnel Development Committee.

Any shareholder may obtain free of charge a printed copy of our Governance Committee Charter by sending a written 
request to Investor Relations, Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701.  You can 
also view and print a copy of our Governance Committee Charter by clicking on the “Governance” tab at the Investor Relations 
page of our website at www.ngsgi.com.

Nominating Committee

The functions of our Nominating Committee include:

•  identifying individuals qualified to become board members, consistent with the criteria approved by the 

Board;

•  recommending Director nominees and individuals to fill vacant positions; and

•  overseeing executive development and succession and diversity efforts.

The members of the Nominating Committee are John W. Chisholm (Chairman), David L. Bradshaw, and Charles G. 
Curtis. Our Board of Directors has determined that each of the Nominating Committee members is independent as defined under 
the applicable NYSE rules and listing standards. During the last fiscal year there were four meetings of the Nominating Committee.

Any shareholder may obtain free of charge a printed copy of our Nominating Committee Charter by sending a written 
request to Investor Relations, Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701.  You can 
also view and print a copy of our Nominating Committee Charter by clicking on the “Governance” tab at the Investor Relations 
page of our website at www.ngsgi.com.  Our Nominating Committee does not have a diversity policy; however, as discussed below, 
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.

Our Nominating Committee will consider a Director candidate recommended by a shareholder.  A candidate must be 
highly qualified in terms of business experience and be both willing and expressly interested in serving on the Board.  A shareholder 
wishing to recommend a candidate for the Committee’s consideration should forward the candidate’s name and information about 
the candidate’s qualifications to Natural Gas Services Group, Inc., Nominating Committee, 508 West Wall Street, Suite 550, 
Midland, Texas 79701, Attn.: John W. Chisholm.  Submissions must include sufficient biographical information concerning the 
recommended individual, including age, employment history for at least the past five years indicating employers' names and 
description of the employer’s business, educational background and any other biographical information that would assist the 
Committee in determining the qualifications of the individual.  The Committee will consider recommendations received by a date 
not later than 120 calendar days before the date our proxy statement was released to shareholders in connection with the prior 
year’s annual meeting for nomination at that annual meeting.  The Committee will consider nominations received after that date 
at the annual meeting subsequent to the next annual meeting.

The Committee evaluates nominees for Directors recommended by shareholders in the same manner in which it evaluates 

other nominees for Directors.  Minimum qualifications include the factors discussed above.

Director Independence

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 Governance and Personnel 
Development Charter, (“Governance Charter”) which are consistent with the NYSE listing standards:  David L. Bradshaw, John 
W. Chisholm, Charles G. Curtis, and William F. Hughes, Jr. A copy of Exhibit A to our Governance Charter is available at our 
website, www.ngsgi.com, under the heading “Investor Relations—Governance.”  The Board has made an affirmative determination 
that each of the four 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.

11

 
 
The Board’s Leadership Structure

Under our Corporate Governance Guidelines, our Chief Executive Officer also serves as our Chairman of the Board, and 
that person is responsible to the Board for the overall management and functioning of the company.  Stephen C. Taylor serves as 
both Chairman of the Board and our President and Chief Executive Officer (“CEO”).  The Board believes this is the most effective 
Board leadership structure at the present time and believes that Mr. Taylor, in his role as Chairman/CEO, has the ability to execute 
on both our short-term and long-term strategies necessary for the challenging marketplace in which we compete.  The independent 
directors believe that Mr. Taylor's detailed and in-depth knowledge of the issues, opportunities and challenges facing us and our 
business make him the best qualified director to develop agendas that ensure that the Board’s time and attention are focused on 
the most critical matters.  Further, as the individual with primary responsibility for managing day-to-day operations, Mr. Taylor 
is best positioned to chair regular Board meetings and ensure that key business issues and risks are brought to the attention of our 
Board and/or Audit Committee.    

Each of our directors, other than Mr. Taylor, is independent, and the Board believes that the independent directors provide 
effective oversight of management.  The Board may subsequently decide, however, to change that leadership structure which 
would require a revision to our Corporate Governance Guidelines. The Board believes that it has in place safeguards to ensure 
that we maintain the highest standards of corporate governance and continued accountability of the CEO to the Board. These 
safeguards include:

•  All members of the Board are independent directors except for Mr. Taylor.

•  Each of the Board’s standing committees, including the Audit, Compensation, Governance and Nominating 
Committees, are comprised of and chaired solely by non-employee directors who meet the independence 
requirements under the NYSE listing standards and other governing laws and regulations. As noted above, 
these committees meet frequently.

•  Review and determination of Mr. Taylor’s compensation and performance remains within the purview of 

the Compensation Committee.

•  The independent directors continue to meet in executive sessions without management present to discuss 
the effectiveness of the company’s management, the quality of the Board meetings and any other issues and 
concerns.

Lead Director

To promote the independence of the Board and appropriate oversight of management and to demonstrate our commitment 
to strong corporate governance, the independent directors designate an independent, non-employee director to serve as our Lead 
Director. The Lead Director helps to facilitate free and open discussion and communication among the independent, nonemployee 
directors. The responsibilities of the Lead Director are set forth in our Corporate Governance Guidelines, which is available under 
“Investor Relations - Governance Documents” on our website at www.ngsgi.com. Charles G. Curtis was appointed Lead Director 
in April 2016.

Role in Risk Oversight

Our Board of Directors oversees the management of risks inherent in the operation of our business and the implementation 
of our strategic plan.  Our executive management is responsible for the day-to-day management of risks we face.  The Board is 
periodically advised by management on the status of various factors that could impact our business and operating results, including 
oil and gas industry issues, operational issues (such as compressor manufacturing issues and backlog for compressor equipment), 
legal and regulatory risks. The full Board is also responsible for reviewing our strategy, business plan, and capital expenditure 
budget.     

Our  Board  committees  assist  the  Board  in  fulfilling  its  oversight  responsibilities  in  certain  areas  of  risk.  Our Audit 
Committee serves an important role in providing risk oversight, as further detailed in its charter. One of the Audit Committee’s 
primary duties and responsibilities is to monitor the integrity of our financial statements, financial reporting processes, systems 
of internal controls regarding finance, and disclosure controls and procedures.  The Compensation Committee assists the Board 
with risk management relating to our compensation policies and programs, and the Governance and Nominating Committee assists 
with risk management relating to Board organization, membership and structure, succession planning for our directors and executive 
officers, and corporate governance.

12

 
  
 
SHAREHOLDER ENGAGEMENT

The Natural Gas Service's Board of Directors believes that building long-term relationships with all Company stakeholders 
is vital to our strategy for corporate governance. Our shareholders, who invest in our company and elect the board of directors, 
are entitled to important information about the company's business, policies and practices so they can make informed decisions 
and knowledgeably participate in the governance process.

The Company’s executive management has directly engaged shareholders throughout the year in many diverse ways 
including quarterly conference calls, investor and industry conferences and individual meetings initiated by both the Company 
and shareholders. It is our policy to actively engage our shareholders in dialogue about our business condition, the structure of 
our business and certain governance issues, including executive compensation. The Compensation Committee considers the annual 
stockholders advisory vote, as well as other stockholder input, when reviewing executive compensation programs, principles and 
policies. 

As a result of critiques of our executive compensation plan and the resulting advisory vote on our executive compensation 
structure, we directly engaged key institutional shareholders in a number of ways including supplemental proxy materials providing 
additional descriptive information on our overall executive compensation structure. In addition, since our last Annual Meeting, 
the  Company’s  executive  management  has  directly  engaged  many  of  our  institutional  shareholders  in  discussions  about  our 
executive compensation program. Specifically, we have discussed our executive compensation program with a number of our top 
twenty actively managed holders and met with approximately 75 institutional shareholders since our last annual meeting. As a 
result of those conversations, the Board has considered and adopted certain adjustments to our executive compensation process 
and policies. See "Executive Compensation" beginning on page 16. 

13

CODE OF ETHICS

Our Board of Directors has adopted a Code of Business Conduct and Ethics, or “Code”, which is posted on our website 
at www.ngsgi.com. You may also obtain a copy of our Code by requesting a copy in writing at 508 West Wall Street, Suite 550, 
Midland, Texas 79701 or by calling us at (432) 262-2700.

Our Code provides general statements of our expectations regarding ethical standards that we expect our Directors, officers 
and employees, including our Chief Executive Officer and principal financial officer, to adhere to while acting on our behalf.  Among 
other things, the Code provides that:

•  we will comply with all laws, rules and regulations;

•  our Directors, officers and employees are to avoid conflicts of interest and are prohibited from competing 

with us or personally exploiting our corporate opportunities;

•  our Directors, officers and employees are to protect our assets and maintain our confidentiality;

•  we are committed to promoting values of integrity and fair dealing; and that

•  we are committed to accurately maintaining our accounting records under generally accepted accounting 

principles and timely filing our periodic reports.

Our Code also contains procedures for our employees to report, anonymously or otherwise, violations of the Code.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Compensation Discussion and Analysis

This compensation discussion and analysis provides information regarding our executive compensation program in 2015

for the following executive officers of the Company (collectively, the "named executive officers").

Stephen C. Taylor, our Chairman, President, and Chief Executive Officer;

G. Larry Lawrence, our Chief Financial Officer; and

James R. Hazlett, our Vice President-Technical Services.

Introduction and Overview

The Compensation Committee or, the “Committee,” of the Board of Directors is responsible for determining the types 
and amounts of compensation we pay to our executives. The Committee operates under a written charter that you can view on our 
website at www.ngsgi.com.  The Board of Directors has determined that each member of the Committee meets the independence 
and financial literacy requirements of the NYSE. The Board determines, in its business judgment, whether a particular Director 
satisfies the requirements for membership on the Committee set forth in the Committee’s charter. None of the members of the 
Committee are current or former employees of Natural Gas Services Group.

The Committee is responsible for formulating and administering our overall compensation principles and plans.  This 
includes establishing the compensation paid to our CEO, meeting and consulting with our CEO to establish the compensation paid 
to our other executive officers, counseling our CEO as to different compensation approaches, administering our stock equity plans, 
monitoring adherence to our compensation philosophy and conducting an annual, and sometimes more frequent, review of our 
compensation programs and philosophy regarding executive compensation.

The  Committee  periodically  meets  in  executive  session  without  members  of  management  or  management  Directors 

present and reports to the Board of Directors on its actions and recommendations.

Compensation Philosophy and Objectives

Our compensation philosophy is to provide an executive compensation program that:

•  rewards  performance  and  skills  necessary  to  advance  our  objectives  and  further  the  interests  of  our 

shareholders;

•  is fair and reasonable and appropriately applied to each executive officer;

•  is competitive with compensation programs offered by our competitors; and

•  serves as an adequate retention tool in a competitive market.

The overall objectives of our compensation philosophy are to:

•  provide  a  competitive  level  of  current  annual  income  that  attracts  and  retains  qualified  executives  at  a 

reasonable cost to us;

•  retain and motivate executives to accomplish our company goals;

•  provide  long-term  incentive  compensation  opportunities  at  levels  appropriate  for  the  respective 

responsibilities and performance of each executive;

•  align compensation and benefits with our business strategies and goals;

•  encourage the application of a decision making process that takes into account both short-term and long-

term risks and the sometimes volatile nature of our industry; and

•  align the financial interests of our executives with those of our shareholders through the potential grant of 

equity based rewards.

16

   
 
 
 
 
 
 
 
 
 
Our Committee supports these objectives by emphasizing compensation arrangements that we believe are reasonable and 
will attract and retain qualified executives and reward them for their efforts to further our long-term growth and success.  At the 
same time, we remain cognizant of and aim to balance our executive compensation arrangements with the interests and concerns 
of our shareholders. 

The following summary highlights our commitment to executive compensation practices that align the interests of our 

executives and stockholders:

WHAT WE DO

WHAT WE DON’T DO

No gross-ups - executive officers are not 
eligible to receive any tax reimbursement 
payments or “gross-ups” in connection with 
any severance or change-in-control payments 
or benefits

Limited perquisites - with the exception of a 
car allowance for our officers and certain 
nominal expense reimbursements as detailed 
in the Summary Compensation Table that 
follows this CD&A, we do not provide any 
perquisites

Prohibition of hedging and pledging shares 
- we do not permit hedging or pledging as 
collateral for a loan nor do we permit our 
executives or non-employee directors to

We have chosen to implement a relatively streamlined compensation framework for our executives.  We feel that our 
compensation philosophies and practices are appropriate given our relatively small size as a public company. By continuing a 
relatively streamlined compensation framework for our executives, we believe that we are able to establish a higher degree of 
transparency, understanding and certainty for our executives as well as the investing public, while at the same time avoiding 
complex benefit packages and agreements that can be, in some ways, difficult to understand and require significant time and cost 
to properly administer. In the end, we believe our compensation arrangements provide the desired results: fair and reasonable pay 
for achievements beneficial to Natural Gas Services Group, Inc. and its shareholders.  

Advisory Vote on Compensation; Shareholder Engagement

At our 2015 Annual Meeting, less than 50% of the votes cast on the annual advisory “Say-on-Pay” proposal were cast 
in support of the compensation of our named executive officers. This was significantly lower than the support levels of previous 
years. The results were disappointing since we believe the vote was the result of the influence of recommendations of certain proxy 
advisory  firms,  both  of  which  advise  institutional  investors  on  voting  on  annual  proxy  matters. We  believe  that  their  reports 
contained factual errors and assumptions that resulted in questionable conclusions and recommendations. Our specific objections 
to their reports were detailed in supplementary proxy materials that were distributed last year. It is important to note that while 
the proxy advisory firms felt that our general compensation structure was lacking in some areas there was no lack of alignment 
in their ‘pay for performance’ metric and, in fact, they complimented the compensation committee for their continued rigor in 
setting financial targets.

Although this was a non-binding advisory vote, the Company’s Board of Directors takes the results of this vote seriously, 
and during 2015 the Company’s Board of Directors and executive management deliberated extensively over the results of last 
year's "Say-on-Pay" vote and engaged in meaningful review of its corporate governance and executive compensation matters with 
advisors as well as other stakeholders.

While the Compensation Committee and full Board believes that our executive compensation program and corporate 

governance policies are strong and have served us well, it recognizes the changing compensation and governance landscape. 

18

 
Below is a summary of what we heard and the actions we took in response:

Compensation and Governance
Concerns
Insufficient Risk Mitigators (i.e.,
lack of clawback policy and stock
ownership guidelines)

Responses to the Concerns
   We have adopted both a Clawback Policy covering our executive officers and Stock 
Ownership Guidelines covering our executive officers and members of our Board of 
Directors. We do note that our company has never had a financial restatement and that 
each  officer  and  director  presently  maintains  their  stock  holdings  in  excess  of  the 
minimum guidelines.

One Year Vesting of Restricted
Stock Grants to Executive Officers

   The  Compensation  Committee  approved  a  new  framework  for  our  long-term  equity 
compensation.  With respect to our recent restricted stock awards to our executive officers 
for  fiscal  2015  (granted  in  early  2016),  such  awards  vest  over  two  years  and  future 
awards will vest in one-third increments over three years.

Excessive Cash Severance

   We  do  not  feel  that  the  cash  severance  benefits  for  our  Chief  Executive  Officer  are 
excessive. Any change of control severance requires a ‘double-trigger’ to be payable 
and the triggers are limited to the standard "good reason" events (see page 43).  We 
believe the severance benefits are within the norms of companies in our industry that 
exhibit a similar performance profile that we do, i.e., industry leading total shareholder 
returns in each of the past one, three and five year periods.  Please see the charts on page 
23 and the 2015 performance achievements below.  The cash severance due to our CEO 
in connection with "good reason" events (typically be an involuntary occurrence) equates 
to  approximately  three  years  of  total  compensation  based  upon  a  year  of  good 
performance, which the Company has consistently demonstrated.

Lack of Lead Independent Director

   We have  had  an  appointed  lead  director for  years,  but  have  amended  our  Corporate 
Governance Guidelines to include the public identification and acknowledgment of a 
lead independent director. Charles G. Curtis, our longest tenured independent director, 
has been formally appointed as our lead director.

Targeting 75th percentile for CEO's
total compensation

Our CEO's total compensation (base pay and short and long term incentives) has been 
between the 50th and 75th percentile when compared to peer group companies with the 
final approved compensation being a  combination of the CEO's and the Company's 
performance. Typically, although it can vary, base salary of our CEO has been in the 
50th  percentile  range  while  long  term  incentives  are  employed  to  increase  the 
compensation package to competitive levels. This allows the Compensation Committee 
to annually adjust the CEO's long term incentives in keeping with shareholder returns 
and Company performance. We think this is an appropriate alignment of pay relative to 
performance of the company and the competitive market. Supporting this practice is the 
fact that the Company has performed in the top 15% to 25% of peer group companies 
for Total Shareholder Return in the last one, three and five year periods (please see pages 
22 and 23 for relevant data).  Our Compensation Committee believes this performance 
has justified total compensation being awarded in the 75th percentile range in recent 
years. However, in the future, if the relative performance of the Company lags our peer 
group of companies, then the CEO’s total compensation will be evaluated under those 
circumstances.

Awarding  long-term  equity  awards 
on a purely discretionary basis with 
minimum awards guaranteed

In the future, long-term equity awards will be based on a combination of the relative 
TSR (Total Shareholder Return) of the Company when compared to our peer group of 
companies and a discretionary component that shall be evaluated by the Compensation 
Committee.

In addition to the foregoing, other concerns made by the proxy advisory firms are discussed elsewhere in this section.

Fiscal Year 2015 Performance

In 2015, our financial performance demonstrated extremely positive results and continued to demonstrate a financial 
condition that provided stability and excellent shareholder value in a very challenging time for a service company in the oil and 
gas industry. Some of our financial and operational highlights include:

• 

Increasing cash and cash equivalents from $6.2 million to $35.5 million in 2015;

•  Maintained long-term debt at a continuing, very low level (less than $500,000);

•  Total revenue decreased only 1.1% in 2015 compared to 2014, a record revenue year. This made 2015 the second highest 

revenue year in the company’s history, a significant achievement considering the operating environment in 2015; 

•  Decreasing capital expenditures from $53.3 million in 2014 to $12.5 million in 2015 demonstrating a timely and quick 

response to the deteriorating oil and gas industry environment;

•  The Company has self-funded growth capital expenditures in excess of $185 million since 2010;

•  Operating cash flow as a percentage of revenue was 43% in 2015, increasing from 35.6% in 2014, making the Company 

an  industry leader in this category;

• 

Free cash flow ( operating cash flow less capital expenditures) as a percentage of revenue was 30.3% in 2015 compared 

to (19.4%) in 2014, and compared to the S&P500 in reporting 9% in 2015 when compared to 2014;

•  Maintained adjusted EBITDA (as defined on page 24) at 44-45% of revenue in both years while limiting 2015 adjusted 

EBITDA deterioration to only 3% in 2015; 

• 

Increased average gross margins in our core rental business from 60% in 2014 to 62% in 2015, notwithstanding continuing 

pressures on revenue and pricing due to the significant fall-off in oil and gas industry; 

• 

Increased compressor sales revenues by 27% from 2014 to 2015;

•  Maintained SG&A expenses at 11% of total revenue in both 2014 and 2015 -- the lowest among our public peers;

• 

Finalized development, and introduced two new gas compression products, a 500 horsepower CiP compressor frame/

package and a 50HP-100Hp Vapor Recovery Unit (VRU) product line; and

• 

For 2015, the Company's common stock price slipped only 3%, while identified public peers were down 43.5%, the OSX 

index (oil service sector) was off 25.2%, West Texas Intermediate (WTI) fell 30.5% and the U.S. land rig count decreased 

by 61.5%.

•  supplemental executive retirement plans/benefits.

Assistance Provided to the Committee

The  Committee  makes  all  compensation  decisions  regarding  our  executive  officers.  Stephen  C.  Taylor,  our  Chief 
Executive Officer, annually reviews the performance of each of our executive officers (other than the Chief Executive Officer 
whose performance is reviewed by the Committee) and presents recommendations to the Committee with respect to salary and 
cash bonus percentage adjustments and restricted stock grants for our executives (other than the Chief Executive Officer whose 
salary, cash bonus percentage adjustments and restricted stock grants are determined solely by the Committee).  The Committee 
may exercise its discretion in modifying any recommendations made by our Chief Executive Officer.

The Committee also seeks the input and insight of Mr. Taylor concerning specific factors that Mr. Taylor believes to be 
appropriate for the Committee’s consideration and which the Committee may not be aware of, such as extraordinary efforts or 
accomplishments of our executive officers.  Mr. Taylor also advises the Committee on general topics such as the morale of our 
executives.

Natural Gas Services Group’s accounting and human resources departments assist the Committee in the compensation 

process by gathering and organizing data, which is then presented to the Committee by Mr. Taylor for the Committee’s review.

In late 2012, our Compensation Committee hired an independent compensation consultant, Longnecker & Associates 
(“Longnecker”), to obtain objective, expert advice and assist with compensation matters concerning our Chief Executive Officer 
and Directors.  Longnecker advised the Compensation Committee on a variety of compensation related issues in 2015 with respect 
to our Chief Executive Officer, including:

•  competitive pay analysis on executive compensation;

•  pay levels of Chief Executive Officers; and

•  our executive compensation program design, including short-term incentive plan design, long-term incentive 

plan design, and pay mix.

In the course of conducting its activities, Longnecker communicated with the Compensation Committee and presented 
its findings and recommendations for discussion. During 2015, Longnecker also met with our Chief Executive Officer to review 
its compensation report.

In 2014 and 2015, Longnecker did not provide any services to the Company, or receive any payments from the Company, 
other than in its capacity as a consultant to the Compensation Committee. The Compensation Committee has assessed whether 

21

 
 
 
 
 
 
 
 
  
 
 
 
the services provided by Longnecker raised any conflicts of interest pursuant to the SEC rules, and has concluded that no such 
conflicts of interest existed during 2014 or 2015.

Competitive Pay Analysis

To evaluate the competitiveness of our Chief Executive Officer's base salary, target total cash compensation (i.e., base 
salary plus target short-term cash incentive award), long-term incentive awards, and total direct compensation (i.e. base salary, 
target short-term cash incentive award, and long-term incentive awards), Longnecker annually provides the Committee competitive 
pay information derived from a custom peer group that is reviewed each year (the “Custom Peer Group”) and referred to a variety 
of published compensation surveys. The companies comprising the Custom Peer Group in Longnecker’s compensation report 
used in connection with 2015 included:

The Compensation Committee, with the assistance of the compensation consultant, reviewed the companies comprising 
the Custom Peer Group in order to maintain its appropriateness for the competitive pay analysis. These companies were generally 
selected since they are all companies in the energy and energy services industry and have various rental, leasing or manufacturing 
components in their business with all having an acceptable range of relatively similar annual revenues and market capitalization.  
The Compensation Committee believes the Custom Peer Group reflects our current competitors for employee talent and that it 
provides an appropriate peer set for the purposes of evaluating our pay practices and the Chief Executive Officer’s pay levels.

The published compensation surveys consisted of the following:

•  Economic Research Institute -- Executive Compensation Assessor

•  Tower Watson -- Top Management Compensation

•  Mercer, Inc. -- Executive General Benchmark Survey

•  Kenexa -- CompAnalyst Benchmark Survey

•  WorldatWork -- Total Salary Increase Budget Survey

The Compensation Committee used the competitive pay information and surveys as a “market check” to ensure, in its 
subjective judgment, that the Chief Executive Officer’s base salary, target total cash compensation, long-term incentive awards 
and total direct compensation remain competitive. The Compensation Committee does not target any individual pay component 
to fall within a specific range or percentile of the competitive pay information. While the competitive pay information is important 
to the Compensation Committee’s approval process, it is just one of several factors considered by the Compensation Committee 
in approving executive compensation and the Compensation Committee has discretion in determining the nature and extent of its 
use.

Individual and Company Performance - Base Salary and Equity Awards

The Compensation Committee also evaluates compensation, particularly base salary levels and equity awards (restricted 
stock awards), through an analysis of each executive officer’s individual performance and the overall performance of Natural Gas 
Services Group, our goal being to strengthen the link between what we pay our executives and the performance of Natural Gas 
Services Group.  Factors the Committee considers in our analysis include:

•  the individual performance, leadership, business knowledge and level of responsibility of our officers;

•  the particular skill-set and longevity of service of the officer;

•  the effectiveness of the officer in implementing our overall strategy; and

•  the general financial performance and health of the Company.

Our CEO is additionally evaluated on his specific ability and effectiveness with respect to shareholder and customer 

engagement. 

Specific Company Financial Metrics - Cash Bonuses

With respect to compensation we pay in the form of cash bonuses, the Committee sets performance levels for three specific 
company financial metrics.  The Committee relies on whether these levels are achieved and the individual performance of our 
executive officers to determine whether cash bonuses are awarded and the amounts of such bonuses.  The three financial metrics 
the Committee considers are:

•  total revenues;

•  adjusted EBITDA; and

•  adjusted net income before taxes.

Adjusted EBITDA is calculated from our audited financial statements by adding to net income, or loss, (1) amortization 
and depreciation expense, (2) interest expense (3) provision for income tax expense and (4) loss on retirement of rental equipment.

We believe that our core executive compensation mix of base salary, cash bonuses and equity awards, while fairly limited, 
presently provides enough diversity for us to link executive compensation to our short-term and long-term objectives.  For instance, 
base salary and cash bonuses generally relate to short-term achievements and objectives while equity awards are more closely 
linked to the long-term objectives of earnings per share and increased market value of our common stock or maintenance of market 
value in periods of depressed industry performance, such as during the past two years.

Base Salary

We provide our executive officers and other employees with base salary to compensate them for services rendered during 
the fiscal year.  Each year the Committee receives base salary recommendations from our Chief Executive Officer for all of our 
executive officers (other than our Chief Executive Officer whose base salary is evaluated by the Committee on an annual basis). 

In January 2015, the Compensation Committee reviewed the 2014 performance of our Chief Executive Officer, Stephen 
C. Taylor, along with the competitive pay information provided in Longnecker’s report, in setting Mr. Taylor's base salary for 
2015. Before the increase in salary for 2014, Mr. Taylor’s base salary fell to slightly less than the 50th percentile bracket in the 
Company’s peer group.  In connection with that review, the Committee increased the base salary of Mr. Taylor from $505,175 in 
2014 to $543,063 in 2015, which moved Mr. Taylor’s base salary to approximately the 63rd percentile bracket. The increase was 
made in recognition of Mr. Taylor’s leadership and contributions to the Company's strong 2014 financial and operational results, 
which included:  (i) increasing total gross margin, exclusive of depreciation and amortization, by 11.4% to $53.8 million for 2014
from $48.3 million for 2013; (ii) achieving in 2014 record high revenue of $97 million, a 9.0% increase in revenue from 2013; 
(iii) a 7% increase in EBITDA; generating $34.6 million from operations, while investing $53.1 million in capital for equipment; 
(iv) controlling SG&A expense to 10.6% of revenues; increasing rental revenue by 14.4%; internally funding over $175 million 
in growth capital since 2010 while maintaining a very low debt level when compared to competitors; (v) maintaining high margins 
and maintaining high ratios of operating income, net income and EBITDA when compared to gross revenues relative to competitors; 
(vi) aggressive expansion into new geographic areas; (vii) positioning our business to emphasize servicing oil and gas production 

24

 
 
 
 
 
 
 
rather than drilling projects in order to offset drilling slowdowns as witnessed in the latter half of 2014; and (viii) maintaining 
safety performance. 

While the Compensation Committee reviewed the competitive pay information in connection with setting Mr. Taylor's 
base salary adjustments, together with his contributions toward our goals, the Compensation Committee did not target his base 
salary to fall within a specific range or percentile of the competitive pay information.

With respect to our other two named executive officers other than our CEO, James Hazlett, our Vice President of Technical 
Services, base salary for 2015 was $200,000 compared to $190,000 for 2014. The base salary of G. Larry Lawrence, our Vice 
President and Chief Financial Officer, for 2015, was $187,000 compared to $170,000 for most of  2014.  We continue, as we have 
in the past, to rely on the following factors in evaluating and determining the amount of compensation we pay these executives:

•  our  general  knowledge  of  executive  compensation  levels  in  the  natural  gas  compression  industry  and 

similarly sized energy service companies;

•  each executive’s individual performance and the overall performance of Natural Gas Services Group; and

•  specific company financial metrics and the application of specific weights to such metrics.

The applicability of these factors varies depending on the type of compensation being evaluated and determined.  For 
instance, we do not rely on weighted company financial metrics to evaluate and determine base salary levels (which are competitively 
set to the market), but the achievement of pre-set financial metrics are the primary means through which we evaluate and determine 
the amount of the cash bonuses we award to our executives. Below is a more detailed discussion of how these factors apply to the 
different types of compensation we utilize.

Short-Term Incentives - Annual Incentive Bonus Plan

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 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 2015, the Committee maintained Mr. Taylor’s target 
award opportunity to up to 100% of his base salary.  Target award opportunity was 50% of average base salary for Messrs. Lawrence 
and Hazlett.

In 2015, 90% of an executive officer’s IBP award was based on achievement of company financial objectives relating 

to:

•  total revenues;

•  adjusted EBITDA; and

•  adjusted net income before taxes.

Each  of  these  three  components  accounts  for  30%  of  the  total  company  financial  objective  portion  of  the  IBP.  The 
remaining 10% of an executive officer’s IBP award is based upon individual performance as evaluated by our CEO (except with 
respect to our CEO whose individual performance is evaluated by the Committee).

Each year, the Committee sets a performance level for each component of the company financial objective portion of the 
IBP.  The payment of awards under the IBP is based upon whether these performance levels are achieved for the year. Payout on 
each of the three financial objectives is as follows:

•  75% of the bonus amount attributable to a financial component will be paid if we achieve at the "threshold" 

amount;

•  100% of the bonus amount attributable to a financial component will be paid if we achieve the "target" 

amount; and

•  125% of the bonus amount attributable to a financial component will be paid if we achieve the "stretch" 

amount.

25

 
 
 
 
 
 
 
For performance achievement between the set financial objectives, the board has discretion to prorate the amount of the 

award.

The following table sets forth the bonus financial criteria and performance levels set by the Committee and compares 

such performance levels to actual performance achieved and the resulting bonus payout percentages earned in 2015:

As noted in the tables above, actual financial performance for 2015 exceeded the "stretch" level in each of the three 
financial metrics set for 2015, thereby entitling each of the named executive officers to 125% of the maximum bonus payout for 
each of the three financial metrics.

With respect to the personal performance criteria, the Committee awarded Messrs. Taylor, Lawrence and Hazlett the 
maximum amount payable under this component, or 10% of the maximum bonus amount that could have been earned in 2015. In 
addition to the Committee's non-quantitative evaluation of each executive's performance,  with respect to all of the named executives, 
the Committee made this award in recognition of the Company's 2015 financial and operational performance. 

With respect to Mr. Taylor’s personal performance criteria, the Committee based its full award on (i) quickly reacting to 
the deteriorating market by cutting capital expenditures by 77% in 2015 versus 2014; (ii) utilizing a combination of aggressive 
(new product introductions and expanded sales coverage) and defensive (cost cutting and strategic pricing) measures to guide the 
Company through the worst downturn in decades; and (iii) his continued ability to maintain superior cost control, industry leading 
margins in operating income, adjusted EBITDA and cash flow.

With respect to Mr. Lawrence’s personal performance criteria, the Committee also based its full award on his success in 
(i) initiating and managing the R&D tax credit process that resulted in appreciable tax credits; (ii) leading implementation of our 
SEC-mandated conflict mineral reporting and tracking process; and (iii) initiating EDI with our major customers for more efficient 
and timely processing of invoices.

With respect to Mr. Hazlett’s personal performance criteria, the Committee also based its full award on his (i) efficiently 
managed the severe contraction in our compressor fabrication throughput; (ii) leading the final engineering design and development 
of our new 500 horsepower compressor frame and VRU (Vapor Recovery Unit) product offerings; and  (iii) maintaining an efficient 
level of engineering staffing that enabled the Company to consistently respond to customer bid requests and ‘win’ the work.

With respect to the rigor if the IBP financial targets, in 2014 the company’s officers were awarded only 77.5% of their 

target bonus in spite of 2014 being a record year for the company.

Long-Term Incentives - Restricted Stock Awards

We consider restricted stock to be a type of long-term incentive compensation that motivates our executive officers to 
work toward our long-term growth and allows them to participate in the growth and profitability of Natural Gas Services Group.  We 
believe that restricted stock aligns the interests of our executive officers with our shareholders in that our executive officers will 
benefit from the restricted stock only to the extent that the value of our common stock increases. With the exception of Mr. Taylor, 
our Chief Executive Officer, the number of shares of restricted stock granted to an executive officer is based on a subjective 
determination of an officer’s individual performance and his current contributions and potential for future contributions to the 
overall performance of Natural Gas Services Group. In Mr. Taylor’s employment agreement we have agreed to award Mr. Taylor 
a restricted stock award or equivalent equity awards in January of each year with an aggregate minimum value equal to at least 
175% of his Base Salary, subject to current vesting terms and other standard terms which shall be established by the Compensation 
Committee taking into account the performance of the Company, Mr. Taylor and industry norms.  Our compensation consultant 
concurred with our approach relating to long-term incentives and recommended that we continue the practice.  

In 2009, we adopted the 2009 Restricted Stock/Unit Plan (the “Plan”) and it went into effect upon its approval by our 
shareholders at our 2009 annual meeting.  We typically grant awards under the Plan to our executive officers and Directors during 
the first quarter of each year after reviewing the Company's operational and financial results from the previous year.  

During the first and second quarters of 2016, the Company granted the following restricted stock awards in connection 

with our 2015 financial and operational results and personal accomplishments of our named executive officers:

Stephen C. Taylor, CEO and President
James R. Hazlett, Vice President - Technical Services

Pursuant to Mr. Taylor's employment agreement, we are required to grant a restricted stock award or equivalent equity 
awards in January of each year with an aggregate minimum value equal to at least 175% of his Base Salary.  See “Compensation 
Agreements with Management” beginning on page 41 of this Proxy Statement for information concerning Mr. Taylor’s employment 
agreement.

The Committee also reviewed Mr. Taylor's total compensation level along with Company's performance and Mr. Taylor's 
personal performance in connection with determining the value of the 2015 restricted stock award. As a result of the Committee's 
review, the Committee awarded Mr. Taylor (i) 44,284 shares of restricted common stock pursuant to the terms of his employment 
agreement and (ii) an additional 31,631 shares of restricted common stock in recognition of our  2015 financial and operational 
results and performance, for a total award of 75,915 shares of restricted common stock.  The restricted shares are subject to a two 
year vesting period (half of the shares vest on the first anniversary date and the remaining half on the second anniversary date), 
although such vesting is subject to acceleration and will immediately vest in the case of (i) death, disability or retirement of the 
recipient employee, or (ii) a change of control in the Company, as set forth in the Plan.

On April 6, 2016, the Compensation Committee awarded 20,000 shares of restricted common stock to each of G. Larry 
Lawrence, our Chief Financial Officer and James R. Hazlett, our Vice President-Technical Services. The restricted shares are 
subject to a two year vesting period (half of the shares vest on the first anniversary date and the remaining half on the second 
anniversary date). All of the restricted shares are subject to acceleration and will immediately vest in the case of (i) death, disability 
or retirement of the recipient employee, or (ii) a change of control in the Company, as set forth in the Plan.

The additional restricted shares which were issued to Mr. Taylor in excess of the 175% of his Base Salary obligation 
under the terms of his employment agreement, and the restricted stock awards to our other two named executive officers were 
made in recognition of their personal performance and of the Company's 2015 financial and operational performance as set forth 
under "Fiscal Year 2015 Performance" on page 20 of this Proxy Statement. 

Further information concerning these awards is set forth in column (i) of the "Summary Compensation Table" on page  

32 and column (i) of the "Grants of Plan-Based Awards for Fiscal 2015" on page 34.

Other Compensation

We maintain a 401(k) retirement plan in which all of our executives and employees are eligible to participate.  We match 
executive and employee contributions to our 401(k) plan, on an equal percentage basis, with cash contributions.  The Company 
matching portion is equal to one-half of the employee’s annual contribution up to a maximum of 3% of the employee’s salary. Our 
matching amounts for our executive officers are included in column (i) of the “Summary Compensation Table” on page  32.

Total Direct Compensation

In determining the extent to which our chief executive officer compensation program meets the Committee’s compensation 
philosophy and objectives, the Committee considers the competitiveness of total compensation (the aggregate of base salary, annual 
cash bonus incentive payment, and the grant value of long-term incentive plan award). Using the Custom Peer Group data from 
Longnecker’s study and discussing with Longnecker the pay practices of our peers, the total compensation for Mr. Taylor, our 
Chief Executive Officer, was at approximately the 75th percentile bracket which the Committee believed to be warranted considering 
our relatively strong (i) 2015 financial and operational results during a difficult time for companies in the oil and gas industry and 
(ii) total shareholder return when compared to our peer group.

Employment Agreements

We employed Stephen C. Taylor, our President and Chief Executive Officer, in January 2005.  On October 23, 2013, we 
entered into a new written employment agreement with Mr. Taylor. We do not have written employment agreements with any of 
our other executive officers.  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 
immediately upon a change in control 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.  See “Compensation Agreements with 

28

 
 
 
 
 
 
 
 
Management”  beginning  on  page  41  of  this  Proxy  Statement  for  detailed  information  concerning  Mr.  Taylor’s  employment 
agreement, as amended.

Allocation of Amounts and Types of Compensation

Other than the restricted stock awards we grant to our executives from time to time and the determinations made by the 
Committee as to specific target award opportunities under our IBP, the allocation of different amounts and types of compensation 
has not been a consideration for us, except with respect to our Chief Executive Officer whose employment agreement currently 
requires an annual restricted stock award or similar equity award with a value of at least 175% of his base salary.  However, the 
Committee is in the process of revising its long-term equity compensation program to a hybrid performance and discretionary 
methodology. See "Chief Executive Officer Equity Compensation" on page 39.  The Committee has not adopted a specific policy 
or target for the allocation between amounts or types of compensation.  We believe that the use of stock awards in our compensation 
package will align the interests of our management and employees with our stockholders.  Notwithstanding moderately increasing 
the use of stock-based compensation, we intend to maintain and continue our practice of having a simplified, but effective and 
competitive, compensation package.

Change of Control and Severance Arrangements

Our  1998  Stock  Option  Plan,  as  amended,  and  our  2009  Restricted  Stock/Unit  Plan  contains  change  of  control 
provisions.  In addition, Mr. Taylor’s employment agreement contains change of control and severance provisions.  Information 
regarding these provisions is provided under the caption “Potential Payments Upon Termination or Change of Control” on page 
38.

Perquisites

We provide limited perquisites to our executives. The primary perquisites include allowing our executives a choice of 
receiving an automobile allowance or personal use of a company-provided automobile and matching contributions made by Natural 
Gas Services Group under our 401(k) plan.  Although we provide Mr. Taylor with one club membership, since his use of the club 
is limited solely for business entertainment, we have not considered it to be a perquisite and have not valued it as such for inclusion 
in column (i) of the "Summary Compensation Table" on page  32.

Our executives also participate in the same medical, dental and life insurance plans as other employees.  However, we 

pay a greater percentage of the premiums for health insurance for our executives than we do for our other employees.

Limit on Deductibility of Certain Compensation

Provisions of the Internal Revenue Code that restrict the deductibility of certain compensation over $1 million dollars 
per year have not been a factor in our considerations or recommendations. Section 162(m) of the Code currently imposes a $1 
million  limitation  on  the  deductibility  of  certain  compensation  paid  to  specified  executives.  Excluded  from  the  limitation  is 
compensation that is “performance based.” For compensation to be performance based, it must meet certain criteria, including 
being based on predetermined objective standards approved by shareholders. The Committee has not taken the requirements of 
Section 162(m) into account in designing executive compensation. 

Say-on-Pay

At our 2015 Annual Meeting of shareholders held in June 2015, we submitted a proposal to our stockholders regarding 
our  executive  compensation  practices. The  proposal  was  an  advisory  vote  on  the  2014  compensation  awarded  to  our  named 
executive officers (commonly known as a “Say-on-Pay” vote). Excluding broker non-votes, our shareholders disapproved our 
2014 compensation with less than half (48.6%) of the shares that voted on the proposal voting in favor of our 2014 executive 
compensation practices.

As noted at the beginning of this section, the results were disappointing since we believe the vote was the result of the 
influence from recommendations from  proxy advisory firms, of which advise institutional investors on voting on annual proxy 
matters. We  believe  that  their  reports  contained  factual  errors  and  assumptions  that  resulted  in  questionable  conclusions  and 
recommendations, and in June 2015 we sent a letter to the proxy advisory firms which detailed our issues with their reports.  We 
29

  
 
 
 
 
 
 
 
also sent our shareholders a copy of these letters and filed our correspondence with the Securities and Exchange Commission on 
June 15, 2015.  You can access this filing free of charge on the Investor Relations section of our website (www.ngsgi.com).  A 
paper copy is also available, without charge upon written request, at Natural Gas Services Group, Inc., 508 West Wall Street, Suite 
550, Midland, Texas 79701. 

Notwithstanding, we took numerous remedial measures, including:

• 

• 

• 

• 

• 

adopting a clawback policy the covers all executive officers;

adopting executive and director stock ownership guidelines;

extending the vesting terms on restricted stock awards made to our executive officers;

amending our Corporate Governance Guidelines to include a lead independent director.  Charles Curtis, our 
longest tenured independent director, has been appointed as our lead director; and

amending our Bylaws to require a majority vote standard in connection with the uncontested election of Directors 
subject to shareholder approval.

Corporate Governance Policies

To ensure our compensation programs are aligned with the long-term interest of our shareholders, we have adopted several 
governance policies that we expect our executive officers to comply with, including meaningful stock ownership guidelines, a 
pledging and hedging policy and a recapture or “clawback” policy that provides for the recoupment of any performance-based 
payouts made based on financial results that are not in compliance with any financial reporting requirement that requires restatement 
of the Company’s financial statements. In addition, to provide our shareholders with a meaningful role in the election of Directors 
and to enhance our corporate governance standards, we have adopted a "majority vote" requirement in the election of Directors, 
subject to the approval of our Shareholders at the annual meeting (see Proposal 5).  Below are summaries of these new policies.

Compensation Clawback Policy

The  Company  has  adopted  a  compensation  recoupment,  or  “clawback”  policy  intended  to  be  consistent  with  the 
requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). This policy provides 
that, in the event we are required to restate our financial statements as a result of “material noncompliance” with financial reporting 
requirements  under  the  securities  laws,  we  will  recover  from  our  current  and  former  executive  officers  any  incentive-based 
compensation (including equity awards) that is (i) based on material erroneous data, (ii) received during the three-year period 
preceding the date on which the Company becomes required to prepare an accounting restatement, and (iii) in excess of what 
would have been paid if calculated under the restatement.  In addition, the Dodd-Frank Act requires the SEC to issue regulations 
requiring issuers to seek recovery from executive officers in certain circumstances involving financial restatements. The SEC has 
issued proposed regulations implementing this portion of the Dodd-Frank Act. Once the SEC finalizes its regulations regarding 
the required form of a clawback policy under the Dodd-Frank Act, we expect to amend our clawback policy accordingly.

Pledging and Hedging Policy

The Company considers it improper and inappropriate for any director, executive officer or associate to engage in short-
term  or  speculative  transactions  involving  our  Common  Stock.  We  therefore  prohibit  directors,  executive  officers  and  other 
associates from engaging in pledging, short sales or other short position transactions in our Common Stock. We also strongly 
discourage directors, executive officers and other associates from engaging in certain forms of hedging or monetization transactions.

30

 
Director and Executive Officer Stock Ownership Guidelines

The Company has stock ownership requirements for its directors and executive officers. The purpose of the ownership 
requirements is to further our goal of increasing shareholder value and to  further align the interests of our directors and key 
executives with the interests of our shareholders. Satisfaction of the policy requires that individuals attain and retain holdings of 
our common stock with a market value equal to the following multiple of the individual’s compensation, defined as either a 
director’s cash retainer fee or an officer’s base salary.  The table below indicates the stock ownership guidelines for our executive 
officers and Board members:

Executive Officer/Director
CEO
All other executive officers
Non-employee Directors

Stock Ownership Guidelines

 (as a multiple of base salary/annual cash retainer)
3 times Base Salary
2 times Base Salary
1 times Base Annual Cash Retainer

Each person’s stock ownership requirement will be adjusted annually each January 1 to reflect any changes in his or her 
retainer or base salary. Generally, individuals have a five-year period to attain their stock ownership requirements. At any time at 
which  the  individual’s  stock  ownership  requirement  has  not  been  met,  including  during  the  initial  five-year  period  to  attain 
compliance, the individual will be required to retain at least 50% of “Net Shares” received upon vesting of restricted stock, restricted 
stock units and performance units. “Net Shares” are defined to include shares of common stock that are owned by the individual 
after shares are sold, swapped or traded to pay applicable withholding taxes. Subsequent to achieving the initial stock ownership 
requirement, all directors and executives are required to continuously maintain stock ownership at their specified levels.

If an individual does not meet the applicable ownership requirements, then he or she is subject to certain restrictions upon 
the vesting of equity awards, and may only dispose of shares for particular reasons set forth in the policy.  The policy provides a 
hardship exemption, for which an individual must submit a request to the corporate governance committee. Presently, all of our 
directors and our executive officers have attained or exceeded their ownership requirements.

Majority Vote Standard in Uncontested Director Elections

In April 2016, the Board amended our Bylaws to implement a majority vote standard in uncontested elections of Directors.  
Prior to this amendment, Directors were elected by plurality vote, meaning that nominees for the election of Directors who received 
the greatest number of votes cast in favor of his or her election would be elected to the Board even if such number of favorable 
votes was less than a majority of votes cast in the election.  Under our revised Bylaws, in uncontested elections each Director must 
be elected by an affirmative majority of the votes cast.  Under our new Bylaw provisions in connection with uncontested elections, 
abstentions and broker non-votes will not be counted and will have no effect in determining whether the required majority vote 
has been obtained.  With respect to contested elections (those where the number of nominees exceeds the number of directors to 
be elected), a plurality vote standard will continue to apply. This amendment to our Bylaws requires Shareholder approval at the 
annual meeting (see Proposal 5).

The  Compensation  Committee  will  continue  to  consider  the  outcome  of  Say-on-Pay  votes  when  making  future 

compensation decisions for our named executive officers.

Compensation Committee Report

The Committee has reviewed and discussed the Compensation Discussion and Analysis with management. Based on its 
review and discussions, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis 
be included in our proxy statement for the 2016 Annual Meeting of Shareholders.

No awards were made under the non-equity Incentive Plan for 2015 except as described of the performance goals under 
our Annual Incentive Bonus Plan, or the "IBP." More information regarding the IBP and the calculation of awards is 
provided below and under the caption “Short-Term Incentives - Annual Incentive Bonus Plan” on page 25.

The information shown in this column reflects awards of restricted stock earned in 2015 (but issued in early 2016) our 
named executive officers pursuant to our 2009 Restricted Stock/Unit Plan.

Annual Incentive Bonus Plan

Our Annual Incentive Bonus Plan or, the “IBP,” provides for annual non-equity incentive based compensation in the form 
of  cash  bonuses  to  our  executive  officers.  Our  Compensation  Committee  administers  and  determines  from  year  to  year  the 
executives that are eligible to participate in the IBP.  The Committee establishes target award opportunities for the executives 
eligible to participate in the plan.  These target award opportunities are expressed as a percentage of an executive’s base salary.  An 
executive’s target award opportunity is the maximum cash bonus an executive is eligible to receive in any one year under the IBP.

The Committee establishes annual performance levels for Natural Gas Services Group’s total revenues, adjusted EBITDA 
and  adjusted  net  income  before  taxes  and  assigns  a  weight  of  30%  to  each  of  these  components.  The  executive’s  individual 
performance is assigned a weight of 10%.  Detailed information regarding the IBP and the calculation of awards is provided under 
the caption “Short-Term Incentives – Annual Incentive Bonus Plan” on page 25.

1998 Stock Option Plan

Our 1998 Stock Option Plan provides for the issuance of stock options to purchase up to 750,000 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. On April 5, 2016, 
subject to shareholder approval, the Board of Directors voted to amend and restate the 1998 Plan to extend the 1998 Plan until 
February 28, 2026 and increase the number of shares of common stock issuable under the Plan from 750,000 to 1,000,000. See 
"Proposal 3" on page 50.

As of December 31, 2015, stock options to purchase a total of 414,769 shares of our common stock were outstanding 
under the 1998 Stock Option Plan. There were no shares included that relate to our non-employee directors under the compensation 
arrangements described under the caption “Compensation of Directors” on page 40.

A total of 93,419 shares of common stock were available at December 31, 2015 for future grants of stock options under 

the 1998 Stock Option Plan.

2009 Restricted Stock/Unit Plan

The purpose of our 2009 Restricted Stock/Unit Plan (the “2009 Plan”) is to retain our employees and directors having 
experience and ability, to attract new employees and directors whose services are considered valuable, to encourage the sense of 
proprietorship, and to stimulate the active interest of such persons in our development and financial success. We believe that grants 
of restricted stock and restricted stock units are an increasingly important means to retain and compensate employees and directors. 

General Description

Shares Reserved for Issuance under the 2009 Plan.  A total of 800,000 shares of our common stock are reserved for 
issuance under the 2009 Plan.  The number of shares of our common stock available under the 2009 Plan will be subject to 
adjustment in the event of a stock split, stock or other extraordinary dividend, or other similar change in our common stock or 
capital structure.

Administration.  The Plan is administered by the plan administrator, defined as one or more committees the Company 
designates consisting of independent directors.  The draft of the Plan appoints our Compensation Committee as the administrator 
(the “Committee”).

Generally, the Committee has the authority, in its discretion, (a) to select officers, directors and employees to whom 
awards may be granted from time to time, (b) to determine whether and to what extent, awards are granted, (c) to determine the 
number of shares of our common stock, or the amount of other consideration to be covered by each award, (d) to approve award 
agreements for use under the Plan, (e) to determine the terms and conditions of any award (including the vesting schedule applicable 
to the award), (f) to amend the terms of any outstanding award granted under the Plan, (g) to construe and interpret the terms of 
the Plan and awards granted, and (h) to take such other action not inconsistent with the terms of the Plan, as the Committee deems 
appropriate.

Types of Awards; Eligibility.  Awards of restricted stock and restricted stock units (RSUs) may be granted under the Plan. 
Awards of restricted stock are shares of our common stock that are awarded subject to such restrictions on transfer as the Committee 
may establish. Awards of RSUs are units valued by reference to shares of common stock that entitle a participant to receive, upon 
the settlement of the unit, one share of our common stock for each unit. Awards may be granted to our officers, directors and 
employees and our related entities, if any. Each award granted under the Plan shall be designated in an award agreement.

Terms and Vesting of Awards.  As noted above, the Committee determines the terms and conditions of each award granted 
to a participant, including the restrictions applicable to shares underlying awards of restricted stock and the dates these restrictions 
lapse and the award vests, as well as the vesting and settlement terms applicable to RSUs. When an award vests, we deliver to the 
participant a certificate for the number of shares without any legend or restrictions (except as necessary to comply with applicable 
state and federal securities laws).

In addition to time-based vesting requirements, the Committee is also authorized to establish quantitative and qualitative 
performance goals in order for awards to vest.  For instance, quantitative performance standards, including, but not limited to, 
financial measurements such as (a) increase in share price, (b) earnings per share, (c) total shareholder return, (d) operating margin, 
(e) gross margin, (f) return on equity, (g) return on assets, (h) net operating income, (i) pre-tax profit, (j) cash flow, (k) revenue, 
(l) expenses, and (m) EBITDA,  or other performance goal requirements may be adopted by the Committee and set forth in the 
particular restricted stock or RSU agreement which must be met in order for shares to vest.

Termination  of  Service.  Unless  otherwise  set  forth  in  an  individual  award  agreement,  the  Plan  and  forms  of  award 
agreements provide that in the event a participant’s continuous service with us terminates as a result of death, disability or retirement 
(an “Acceleration Event”), unvested shares or RSUs at the time of termination due to an Acceleration Event will immediately 
become vested, but only to the extent that such unvested shares or RSUs would have vested within the 12 months following the 
Acceleration Event.  However, the Committee may revise this default provision on an individual basis, as it deems advisable.  For 
example, the Committee could elect to accelerate vesting for all unvested shares and/or RSUs upon the occurrence of an Acceleration 
35

 
 
 
 
Event, or conversely provide that all unvested shares and/or RSUs are forfeited upon the occurrence of an Acceleration Event.  In 
the case of a termination of service other than by an Acceleration Event, any unvested shares of RSUs will immediately become 
null and void, except that with respect to Restricted Stock awards, the Board of Directors may vest any or all unvested shares in 
its discretion in the case of any termination of service.

In addition, subject to revision by the Committee, the default provisions of the Plan and form of award agreements provide 
that a Change of Control triggers accelerated vesting of all shares or units.  Under the 2009 Plan, a Change in Control Event is 
generally defined as:

•  a complete liquidation or dissolution;

•  acquisition of 50% or more of our stock by any individual or entity including by tender offer or a reverse 

merger;

•  a merger or consolidation in which we are not the surviving entity; or

•  during any period not longer than 12 consecutive months, members of the Board who at the beginning of 
such period cease to constitute at least a majority of the Board, unless the election, or the nomination for 
election of each new Board member, was approved by a vote of at least 3/4 of the Board members then still 
in office who were Board members at the beginning of such period.

Restricted Stock.  Under an award of restricted stock, we issue shares of our common stock in the participant’s name; 
however, the participant’s rights in the stock are restricted until the shares vest.  If the vesting requirements are not met prior to 
the end of the vesting period, the shares are forfeited.    In connection with an award of restricted stock, since actual shares are 
issued and outstanding, the participant is legally entitled to vote the shares and receive any dividends declared and paid on our 
common stock prior to the satisfaction of the vesting requirements.  However, as discussed above, participants who hold unvested 
restricted stock may not sell, assign or transfer such shares until they have vested.

Restricted Stock Units.  Like a restricted stock award, a restricted stock unit is a grant valued in terms of our common 
stock. Unlike a restricted stock award, none of our common stock is issued at the time the RSU award is granted.  Instead, the 
award is a mere promise to deliver shares of our common stock upon satisfaction of the vesting requirements.  Upon satisfaction 
of the vesting requirements of the award, we then issue and deliver the number of shares subject to the award.  If the vesting 
requirements are not satisfied prior to the end of the vesting period, the units expire and no shares are issued.  Since shares of our 
common stock are not issued in connection with RSUs until such time as the vesting conditions have been satisfied, participants 
in the Plan who receive awards of RSUs will not have any voting rights and will not be entitled to dividends until such time as 
the units vest and shares of our common stock are issued.

Amendment, Suspension or Termination of the Plan.  We may at any time amend, suspend or terminate the Plan. The Plan 
will be for a term of ten (10) years unless sooner terminated. Awards may be granted under the Plan upon it becoming effective, 
but awards granted prior to obtaining shareholder approval will be rescinded if the shareholders do not approve the Plan.  We may 
amend the Plan subject to compliance with applicable provisions of federal securities laws, state corporate and securities laws, 
the Internal Revenue Code, and the rules of the NYSE (or such other stock exchange as our common stock may be traded upon 
at the time).

Change in Capitalization.  Subject to any required action by our shareholders, the number of shares of common stock 
covered by outstanding awards, the number of shares of common stock that have been authorized for issuance under the 2009 
Plan, the exercise or purchase price of each outstanding award, the maximum number of shares of common stock that may be 
granted subject to awards to any participant in a calendar year, and the like, shall be proportionally adjusted by the Committee in 
the event of: (i) any increase or decrease in the number of issued shares of common stock resulting from a stock split, stock 
dividend, combination or reclassification or similar event affecting our common stock; (ii) any other increase or decrease in the 
number of issued shares of common stock effected without receipt of consideration by us; or (iii) any other transaction with respect 
to common stock including a corporate merger, consolidation, acquisition of property or stock, separation (including a spin-off or 
other distribution of stock or property), reorganization, liquidation (whether partial or complete), distribution of cash or other 
assets to shareholders other than a normal cash dividend, or any similar transaction; provided, however, that conversion of any of 
our convertible securities shall not be deemed to have been “effected without receipt of consideration.” Except as the Committee 
determines, no issuance by us of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment 
by reason hereof shall be made with respect to, the number of shares of common stock subject to an award.

As of April 12, 2016, we had issued 611,292 shares of restricted stock under the 2009 Plan, of which 454,634 have vested 

and become unrestricted.

Potential Payments Upon Termination or Change of Control

Our  1998  Stock  Option  Plan  and  2009  Restricted  Stock/Unit  Plan  contains  “change  of  control”  provisions.  These 
provisions are designed to provide some assurance that we will be able to rely upon each executive’s services and advice as to the 
best interests of Natural Gas Services Group and our shareholders without concern that the executive might be distracted by the 
personal uncertainties and risks created by any proposed or threatened change of control and to promote continuity of our executive 
team.

Under our stock option plan, the Committee may adjust the stock options held by our executives upon the occurrence of 
a change of control. With this authority, the Committee may in its discretion elect to accelerate the vesting of any stock options 
that were not fully vested and allow for the exercise of such options as to all shares of stock subject thereto.

Likewise, under our 2009 Restricted Stock/Unit Plan, a change in control will accelerate the vesting of all awards under 
the plan unless the Committee has provided otherwise in a particular award under the plan.  In addition, upon death, disability or 
retirement, any vesting or other restrictions on the restricted stock awards will accelerate or lapse such that all shares underlying 
a restricted stock award will become unencumbered.

As noted in the tables above and summarized below, our named executive officers have stock options and restricted stock 

awards which are subject to certain vesting requirements.

At December 31, 2015, our named executive officers had the following number of unvested restricted stock awards which 

were subject to forfeiture as of that date:

•  Stephen C. Taylor  --  83,590 shares

•  G. Larry Lawrence -- 20,000 shares

•  James R. Hazlett    -- 20,000 shares

Each of these restricted stock awards could have become vested and issued without restrictions on December 31, 2015
assuming a change of control were to have occurred on that date.  In addition, the restricted stock awards would have been issued 
without restrictions on December 31, 2015, assuming the named executive officer had died, became disabled or retired.  The 
closing price of our common stock on December 31, 2015, was $22.30 per share.  Accordingly, on December 31, 2015, had there 
been a change in control event or had the named executive officer died, became disabled or retired, the vesting terms of the restricted 
stock awards would have lapsed and the shares would have become unrestricted.  As a result, there was a potential for Messrs. Taylor, 
Hazlett and Lawrence to realize immediate value upon the lapse of restrictions on restricted stock awards as follows:  Mr. Taylor 
--$1,864,057; Mr. Lawrence --$446,000; and Mr. Hazlett --$446,000.

As described under “Compensation Agreements with Management” on page 41, we entered into a written employment 
agreement with Stephen C. Taylor, President, Chief Executive Officer and Chairman of the Board in October 2013.  Under the 
employment agreement, Mr. Taylor is eligible for certain benefits in connection with a change in control.  These provisions were 
included  in  Mr.  Taylor’s  initial  employment  agreement  with  us  and  were  continued  in  his  current  agreement  as  part  of  our 
negotiations with Mr. Taylor as to the terms of his employment and as an inducement for him to continue his employ with our 
company.  The change of control and severance provisions were designed to promote stability and continuity with respect to Mr. 
Taylor’s employment as our Chief Executive Officer and President.

The following table summarizes the benefits in effect as of December 31, 2015 that Mr. Taylor would receive assuming 
that a qualifying termination (i.e., a termination described in footnote 2 below) in connection with a change in control, death or 
disability or a termination by the Company without cause, or a voluntary termination by Mr. Taylor with and without good reason, 
occurred on December 31, 2015. Those payments that are available generally to salaried employees that do not discriminate in 
scope, terms or operation in favor of executive officers are also not included in this table.

See "Compensation Agreements with Management" beginning on page 41 for definitions and discussion of Mr. Taylor's 
severance package in connection with termination due to change of control, voluntary resignation with good reason or 
termination by the Company without cause. 

In the event of Mr. Taylor’s employment terminates on account of death, disability, or qualified retirement, 100% of 
unvested Restricted Stock awards will immediately vest. 

The value attributable to the acceleration of unvested Restricted Stock awards is based upon the number of awards 
multiplied by the closing price of our common stock ($22.30) on December 31, 2015. 

Chief Executive Officer Equity Compensation

In an attempt to attract and retain critical leadership talent, which the Board of Directors believes is a central element of 
creating durable shareholder value, the Compensation Committee is in the process of restructuring the equity incentive program 
for our Chief Executive Officer. 

Compensation awarded under the new equity compensation program will be primarily based on the Total Shareholder 
Return (TSR) of the Company relative to the TSR of each member of the Company’s peer group over a one-year period. In addition, 
the Compensation Committee will continue to exercise a degree of discretion in administering this equity compensation program 
given the inherent volatility in the oil and natural gas business environment as well as a number of other quantitative and qualitative 
factors. 

As a result of discussions with our stakeholders and CEO, the Compensation Committee intends to target quantitative-

based incentive equity compensation at 175% of the CEO’s base salary.  

Based on the Company’s relative one-year TSR, the Compensation Committee envisions target multiples of the base 

175% level as follows:

TSR Performance Percentile
Number of Peers Outperformed
Multiplier

< 25th
0-2
0

25th
3
.75

50th
6
1.5

75th
9
2.0

39

In addition, as noted above, the Compensation Committee retains discretion to adjust the awards based on other relevant 
quantitative and qualitative performance measures and for both absolute and relative extraordinary achievement in line with the 
objective of attracting and retaining best in class leadership. 

The Compensation Committee intends to formalize this program with the Company's CEO within the next few months 
so that the annual equity award to be granted in 2017 will be made under the new program outlined above.  In addition, as noted 
elsewhere in this Proxy Statement, future awards will be subject to  vesting requirements under which share awards will vest in 
equal one-third tranches on December 31 of the grant year and the subsequent two years.

Compensation of Directors

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.

The following table discloses the cash, equity awards and other compensation earned, paid or awarded, as the case may 

be, to each of our non-employee Directors during the fiscal years ended December 31, 2015, 2014 and 2013.

Nominating and Governance and Personnel Development committees were entitled to an additional quarterly cash fee of $1,250.

Equity Based Compensation Paid to Independent Directors

In 2013, each independent Director received a static grant of 2,500 shares of restricted shares of Company common stock 
for each year.  Beginning in 2014, our Board of Directors revised the Company's compensation policy for independent directors 
so that in lieu of issuing a static 2,500 restricted shares of Company common stock as in past years, the independent directors now 
receive 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 
2015, 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 $103,000 in restricted stock.  In connection therewith, each of our four 
independent directors was granted for 2015 the amount of 5,492 shares of restricted stock pursuant to the Plan, based upon the 
closing price of $18.75 per share as of March 19, 2015, the date of the grant.  The restricted shares are subject to vesting whereby 
no shares will vest during the first year, and then upon the first anniversary date of the award, one-fourth of the shares will vest 
every  three  months  so  that  all  restricted  shares  will  have  vested  on  the  second  anniversary  date  of  the  grant  of  the  award.  
Notwithstanding the vesting schedule, all of the restricted shares are subject to acceleration and will immediately vest in the case 
of (i) death, disability, or retirement of the recipient employee, or (ii) a change of control in the Company, as set forth in the 
Restricted Stock Plan.

Directors who are our employees do not receive any compensation for their services as Directors.

Other

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 2015 was $100,113.  We do not offer non-employee Directors 
travel accident insurance, life insurance or a pension or retirement plan.

Compensation Agreements with Management

On  October  23,  2013,  we  and  Stephen  C.  Taylor  entered  into  a  new  employment  agreement  (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  and  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.  

Base Salary.  Mr. Taylor’s annual 2015 base salary of $543,063 (“Base Salary”) remained the same for the remainder 
of 2015.  However, the Base Salary will be reviewed annually at the beginning of the year by, and may be increased at the discretion 
of, the Compensation Committee of the Board of Directors of the Company (the “Compensation Committee”).

41

 
 
 
 
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 a hundred percent 
(100%) of Base Salary for 2015 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 will be eligible for annual grants of equity-based incentive awards under 
the Company’s equity compensation plans.  The Company has agreed to award Mr. Taylor a restricted stock award or equivalent 
equity awards in January of each year with an aggregate minimum value equal to at least 175% of the Executive's Base Salary, 
subject to vesting terms and other standard terms which shall be established by the Compensation Committee taking into account 
the performance of the Company, Mr. Taylor and industry norms.

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.

Termination. The Company or Mr. Taylor may terminate the agreement prior to the expiration of its Term at any time 

upon written notice.

Severance upon Early Termination. Mr. Taylor will be entitled to the following severance benefits during the first ten 

years of his employment:

(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.

(B) If Mr. Taylor's employment is terminated for Cause or he voluntarily resigns, then he will be entitled to any unpaid 
compensation earned through the date of termination and 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.

After the tenth anniversary date of Mr. Taylor's employment agreement, in the event the Company delivers to Mr. Taylor 

a Notice of Nonrenewal and:

(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 Annul 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 
42

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 fifty 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.

We do not have any written employment agreements with our other named executive officers.

Limitation on Directors’ and Officers’ Liability

Our Articles of Incorporation provide our Directors and Officers with certain limitations on liability to us or any of our 
shareholders for damages for breach of fiduciary duty as a Director or officer involving certain acts or omissions of any such 
Director or Officer.

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.

Even though we maintain Directors’ and Officers’ liability insurance, the indemnification provisions contained in our 

Articles of Incorporation and bylaws remain in place.

Procedures for Reviewing Certain Transactions

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:

• 

• 

• 

• 

any of our Directors, Officers or employees or a nominee to become a Director;

an owner of more than 5% of our outstanding common stock;

certain family members of any of the above persons; and

any entity in which any of the above persons is employed or is a partner or principal or in which such person 
has a 5% or greater ownership interest.

Approval Procedures

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 related party’s relationship to us and interest in the transaction;

the material terms of the proposed transaction;

the benefits to us of the proposed transaction;

the availability of other sources of comparable properties or services; and

•  whether the proposed transaction is on terms comparable to terms available to an unrelated third party or to 

employees generally.

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.

Ratification Procedures

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 then, 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 and the CEO or the Audit Committee will 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 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 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.

We did not have any related party transactions in 2015 with our Officers or Directors.

Section 16(a) Beneficial Ownership Reporting Compliance

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.

Based on a review of Section 16(a) filings furnished to us, all transactions in our equity securities required to be reported 
by Section 16(a) of the Securities Exchange Act of 1934, as amended, were reported on a timely basis, except for the following:  
In January and March of 2015, with respect to the vesting of certain restricted common stock awards, the following of our officers 
and directors inadvertently failed to timely file Form 4's relating to the disposal of the number of  shares listed in connection with

transactions of 1,088 and 4,067 shares; and Stephen C. Taylor - 20,547 shares.  Appropriate Form 4's were filed in June 2015 when 
the error was discovered.

In addition, in December of 2015 Charles G. Curtis inadvertently failed to timely file a Form 4 in connection with the 
exercise of a stock option for 2,500 shares of our common stock.  Mr. Curtis filed a Form 4 reporting the missed transaction in 
January 2016.

All of the foregoing late filings related to exempt transactions under Section 16.

REPORT OF THE AUDIT COMMITTEE

The following report of the Audit Committee of the Company shall not be deemed to be "soliciting material" or to be 
"filed" with the SEC, nor shall this report be incorporated by reference into any filing made by the Company under the Securities 
Act of 1933 or the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates such information 
by reference in such filing.

Our Audit Committee, pursuant to its charter, is responsible for (i) overseeing the integrity of our financial statements; 
(ii) financial reporting processes; (iii) compliance with legal and regulatory requirements; (iv) the independent registered public 
accounting firm qualifications and independence; (v) annually reviewing and assessing the committee's performance and its charger; 
(vi) and the performance of our internal accounting functions and independent registered public accounting firm.

Our independent registered public accounting firm is responsible for performing an independent audit of our financial 
statements in accordance with the Standards of the Public Company Accounting Oversight Board (United States) and to issue a 
report thereon.  The Audit Committee reviews with management our financial statements and management’s assessment of internal 
controls over financial reporting; reviews with the independent registered accounting firm their independent report on the condition 
of the Company's financial statements; and reviews the activities of the independent registered public accounting firm.  The Audit 
Committee selects our independent registered public accounting firm each year.  The Audit Committee also considers the adequacy 
of our internal controls and accounting policies.  While the Audit Committee has the responsibilities and powers set forth in its 
charter,  and  the  Company's  management  and  the  independent  registered  public  accounting  firm  are  accountable  to  the Audit 
Committee, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company's financial 
statements and disclosures are complete and accurate and are in accordance with generally accepted accounting principles and 
applicable laws, rules and regulations.The chairman and members of the Audit Committee are all independent Directors of our 
Board of Directors within the meaning of Section 303A of the New York Stock Exchange Listed Company Manual.

The Audit Committee has reviewed and discussed our audited financial statements with our management.  The Audit 
Committee has also received from, and discussed with, BDO the matters required to be discussed by Public Company Accounting 
Oversight Board Auditing Standard No. 16 (Communications with Audit Committees).  In addition, the Audit Committee has 
received the written disclosures and the letter from our independent registered public accounting firm required by the Public 
Company Accounting Oversight Board in Rule 3200T.  In addition, the Audit Committee has received the written disclosures and 
the letter from our independent registered public accounting firm matters pertaining to their independence.  Based upon the reviews 
and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements 
be included in our Annual Report on Form 10-K for 2015 for filing with the Securities and Exchange Commission.  See “Proposal 
4– Ratification of Appointment of Independent Registered Accounting Firm” on page 55.

Members of the Audit Committee rely, without independent verification, on the information provided to them and on the 
representations made by the Company's management and independent registered public accounting firm. Accordingly, the Audit 
Committee's oversight does not provide an independent basis to determine that management has maintained appropriate accounting 
and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting 
standards and applicable laws and regulations. 

Respectfully submitted by the Audit Committee,

David L. Bradshaw, Chairman

PROPOSAL 2 –  CONSIDERATION OF AN ADVISORY VOTE ON COMPENSATION PROGRAMS FOR ITS 
NAMED EXECUTIVE OFFICERS

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), gives the stockholders 
the  right to endorse or not endorse the compensation of our named executive officers as disclosed in this Proxy Statement in 
accordance  with  the  SEC's  rules.  The  proposal,  commonly  known  as  a  “Say-on-Pay”  proposal,  gives  our  shareholders  the 
opportunity to express their views on the Company's executive compensation.  

At the Company's annual meeting of shareholders held in June 2011, our shareholders recommended that the advisory vote 
on the Say-on-Pay of our named executives in our proxy materials be submitted annually, notwithstanding that our Board of 
Directors recommended that the advisory vote be submitted every third year.  In light of the recommendation of the shareholders, 
we intend to include the Say-on-Pay advisory vote in our proxy materials on an annual basis until the next shareholder vote on 
the frequency of Say-on-Pay or our Board of Directors otherwise determines that a different frequency of Say-on-Pay vote is in 
the best interests of the shareholders.

We are asking our stockholders to indicate whether or not they support the compensation program as described in this proxy 
statement.  This proposal is not intended to address any specific item of compensation, but rather the overall compensation of the 
named  executive  officers  and 
this  proxy 
the  compensation  policies,  methodologies  and  practices  described 
statement.  Accordingly, we ask our shareholder to vote “FOR” the following resolution at our annual meeting:

in 

“RESOLVED, that the shareholders approve the compensation of the Company's named executive officers, as disclosed in 
the Compensation Discussion and Analysis, the compensation tables, and the related disclosure contained in the proxy statement 
set forth under the caption “Executive Compensation” of this proxy statement.”

The  Company  believes  its  compensation  philosophy  and  programs  are  strongly  linked  to  performance  and  results  and 
appropriately aligned with the interests of stockholders.  Our compensation philosophy is to provide an executive compensation 
program that:

•  rewards  performance  and  skills  necessary  to  advance  our  objectives  and  further  the  interests  of  our 

shareholders;

•  is fair and reasonable and appropriately applied to each executive officer;

•  is competitive with compensation programs offered by our competitors; and

•  is appropriately focused on achieving annual financial and operational goals through the Company's cash 
bonus plan and on maximizing stockholder value over the long term, through grants of restricted shares and 
stock options.

The Board of Directors recommends that you vote FOR approval, on an advisory basis, of the compensation programs 
of our named executive officers as disclosed in the Compensation Discussion and Analysis, the compensation tables, and 
the related disclosure contained in the proxy statement set forth under the caption “Executive Compensation” of this proxy 
statement.

PROPOSAL 3 - APPROVAL OF THE AMENDMENT AND RESTATEMENT OF THE 1998 STOCK OPTION PLAN

Proposal

To consider and vote upon a proposal to amend and restate the Natural Gas Services Group, Inc. Stock Option Plan to 

(1) increase the number of shares authorized for issuance thereunder from 750,000 to 1,000,000 shares of common stock and 
(2) extend the term of the Plan for an additional ten years, until February 28, 2026.

History of the Plan and Description of the Proposed Amendment

On December 18, 1998, the Board of Directors adopted the 1998 Stock Option Plan of Natural Gas Services Group, Inc. 
(the “1998 Plan” or simply the “Plan”), and directed that the 1998 Plan be submitted to the shareholders for approval. The 1998 
Plan became effective when it received such approval on December 18, 1998.  On May 9, 2006, the Compensation Committee of 
the Board of Directors voted to amend the 1998 Plan and the amendments were approved by our shareholders at our 2006 Annual 
Meeting of Shareholders (the “2006 Plan”).  The 2006 Plan amendments, among other things, extended the terms of 1998 Plan 
until March 1, 2016 and increased the number of shares of common stock issuable under the 2006 Plan from 150,000 to 550,000.  
On April 15, 2009, the Compensation Committee of the Board of Directors voted to further amend the Plan to add an additional 
200,000 shares of common stock to the Plan, thereby authorizing the issuance of up to 750,000 shares of common stock under the 
Plan and the amendment was approved at our 2009 Annual Meeting of Shareholders.

On April 5, 2016, subject to shareholder approval, the Board of Directors voted to amend and restate the Plan to extend 
the Plan until February 28, 2026 (the “2016 Plan” or simply the “Plan”) and increase the number of shares of common stock 
issuable under the Plan from 750,000 to 1,000,000.

The 2016 Plan amendment will become effective if a majority of the votes cast are in favor of the proposal.  If the 
amendment is not approved, no further options may be granted under the 2006  Plan, although all options granted prior to March 
1, 2016, which continue to be outstanding, will remain in force until such time as the options are either exercised or expire pursuant 
to the terms set forth in such options.

The purposes of the Plan, which are unchanged by the proposed amendment, are to attract and retain the best available 
personnel for positions of substantial responsibility, to provide additional incentive to employees and consultants and to promote 
the success of our business.

Summary Description of the Plan

The following summary of the Plan, as amended and restated, is qualified in its  entirety by reference to the text of the 
Plan, as amended and restated, which is  attached as Appendix A. The Plan has been and will continue to be administered by the 
Compensation Committee of the Board of Directors. The  Compensation Committee has full and final authority, in its discretion, 
to grant  incentive stock options or non-statutory stock options, to select the persons who  would be granted stock options and 
determine the number of shares subject to  each option, the duration and exercise period of each option and the terms and  conditions 
of each option granted.

The Major Provisions of the Plan as amended and restated are as follows:

Eligibility. The Compensation Committee is authorized to grant stock options to any person selected by the Compensation 
Committee, including employees, officers who are also directors of Natural Gas Services Group, directors who are not employees 
of Natural Gas Services Group and consultants.  Incentive stock options may be granted only to employees of Natural Gas Services 
Group.

Option Price. The option exercise price for shares of common stock issued upon exercise of an option is such price as is 
determined by the Compensation Committee. However, for incentive stock options granted to employees the option price will be 
not less than 100% of the fair market value of the Company’s common stock on the date the option is granted, except that if an 
incentive stock option is granted to an employee who owns more than 10% of our outstanding common stock, the option price 
will be not less than 110% of the fair market value of the common stock on the date of grant. Fair market value for purposes of 
the Plan is the closing price of the common stock as reported on the New York Stock Exchange on the relevant date.

50

 
 
 
Duration of Options. Each stock option will terminate on the date fixed by the Compensation Committee, which shall 
be not more than ten years after the date of grant. However, in the case of an incentive stock option granted to an employee who, 
at the time the option is granted, owns stock representing more than 10% of the our outstanding stock, the term of the option will 
be five years from the date of grant or such shorter time as may be provided in the stock option agreement.

Exercise Period.  In the case of incentive stock options, if an optionee’s employment is terminated for any reason, except 
death or disability, the optionee has three months in which to exercise an option (but only to the extent exercisable on the date of 
termination) unless the option by its terms expires earlier. If the employment of the optionee terminates by reason of total and 
permanent disability, the option may be exercised during the period of twelve months following termination of employment.  If 
an optionee dies while an employee or within three months from the date of termination, the right to exercise shall terminate twelve 
months from the date of death.  The options terminate immediately prior to the dissolution or liquidation of Natural Gas Services 
Group, unless the Compensation Committee gives each optionee the right to exercise his option as to all or any part of the option, 
including shares as to which the option would not otherwise be exercisable.  If we sell all or substantially all of our assets or we 
merge with or into another entity in a transaction in which it is not the survivor, options will be assumed or an equivalent option 
will be substituted by the successor corporation, unless the Compensation Committee determines that the optionee has the right 
to exercise the option as to all of the shares, including shares as to which the option would not otherwise be exercisable.  The 
Compensation Committee has the right to alter the terms of any option at grant or while outstanding pursuant to the terms of the 
Plan.

Payment.  Payment for stock purchased on the exercise of a stock option must be made in full at the time the stock option 
is exercised.  The Compensation Committee may, in its discretion, permit payment for the exercise price to be made in cash, check, 
other shares of common stock having a fair market value on the date of exercise equal to the aggregate exercise price of the shares 
as to which the option is exercised, or any combination of such methods of payment, or such other consideration and method of 
payment for the issuance of shares as permitted under the Colorado Business Corporation Act.

Shares That May Be Issued under the Plan.  Prior to the increase in authorized shares set forth in this proposal, a maximum 
of 750,000 shares of our common stock, as may be adjusted as described below, may be issued upon exercise of stock options 
granted under the Plan.  This number includes the number of shares of Natural Gas’ common stock originally authorized in 1998 
(150,000 shares) plus the additional shares added in the 2006 and 2009 amendments (600,000 shares).  In connection with extending 
and restating the Plan, a total of 250,000 additional shares will be authorized pursuant to this proposed amendment.  The 250,000 
additional shares available represent approximately 1.9% of our common stock issued and outstanding on April 18, 2016.  At the 
date of this proxy statement, 241,812 shares of common stock have already been issued under the Plan and 414,769 shares are 
subject to currently outstanding stock options, leaving 93,419 shares of common stock available from the 750,000 shares authorized 
prior to this proposal. The number of shares available under the Plan is subject to adjustment in the event of any stock split, stock 
dividend, recapitalization, spin-off or other similar action. If any stock option terminates or is canceled for any reason without 
having been exercised in full, the shares of stock not issued will then become available for additional grants of options.

    Federal Income Tax Consequences Federal Income Tax Consequences

Incentive Stock Options.  Some of the options granted under the Plan may constitute “incentive stock options” (“ISOs”) 
within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). Under current federal income 
tax rules, there will be no federal income tax consequences to us or an optionee upon the grant of an ISO, nor will an optionee’s 
exercise of an ISO result in income recognition to the optionee or a deduction or other federal income tax consequences to Natural 
Gas Services Group. Although an optionee will not realize ordinary income upon his exercise of an ISO, the excess of the fair 
market value of the common stock acquired at the time of exercise over the option price may constitute an adjustment in computing 
alternative minimum taxable income under Section 56 of the Code and, thus, may result in the imposition of the “alternative 
minimum tax” pursuant to Section 55 of the Code on the optionee.  The tax consequences of a disposition of stock acquired upon 
exercise of an ISO depends upon how long the optionee has held the shares. If an optionee does not dispose of common stock 
acquired through an ISO within two years after the ISO was granted, nor within one year of the ISO’s date of exercise, any gain 
realized upon a subsequent disposition of common stock will constitute long-term capital gain (or loss) to the optionee equal to 
the  difference  between  the  sale  price  of  the  shares  and  the  exercise  price. We  are  not  entitled  to  any  deduction  under  these 
circumstances.  If the optionee fails to satisfy either of the foregoing holding periods, he must recognize ordinary income in the 
year of the disposition, which is referred to as a “disqualifying disposition”. Upon the occurrence of a disqualifying disposition 
of an ISO, the amount of such ordinary income generally is the lesser of (i) the excess of the fair market value of the common 
stock on the date of exercise over the option price or (ii) the actual gain realized upon such disposition.    Any gain in excess of 
the amount taxed as ordinary income will be treated as a long-term or short-term capital gain, depending on how long the stock 
was held (currently a period of more than one year). We will receive a deduction in the amount equal to the amount constituting 
ordinary income to an optionee in the year of the disqualifying disposition (in addition to the employer’s side of payroll/withholding 
taxes paid).

51

 
 
 
Non-statutory Options.  Certain stock options which do not constitute ISOs (“non-statutory options”) may also be granted 
under the Plan. Under current federal income tax rules, there will generally be no federal income tax consequences to us or the 
optionee upon the grant of a non-statutory option so long as the exercise price of the option is equal to or exceeds the fair market 
value of the underlying stock as of the date of grant.  However, the optionee will realize ordinary income upon the exercise of a 
non-statutory option in an amount equal to the excess of the fair market value of the common stock acquired upon the exercise of 
such option over the option price.  We are required to pay the applicable payroll taxes on such income of the optionee, and we are 
required to withhold and pay over to the relevant tax authorities the applicable income tax withholding and employee portion of 
payroll taxes on this income (which the optionee is required to pay over to us). We will receive a corresponding deduction in the 
amount of the income recognized by the optionee (subject to possible limitations imposed by Section 162(m) of the Code) , as 
well as a deduction for the employer’s portion of payroll taxes paid.  Any gain or loss realized upon the optionee’s subsequent 
disposition of such common stock will constitute short-term or long-term capital gain or loss depending on the optionee’s holding 
period following the date of exercise (currently a period of more than one year).  We do not receive a tax deduction for any such 
capital gain.

The federal income tax consequences described in this section are based on laws and regulations in effect on the date of 
this proxy statement, and there is no assurance that the laws and regulations will not change in the future and affect the tax 
consequences of the matters discussed in this section.

Termination of and Amendments to the Plan

     The Board of Directors may terminate or amend the Plan from time to time in any manner permitted by applicable laws and 
regulations, except that no additional shares of our common stock may be allocated to the Plan and no change in the class of 
employees eligible to receive incentive stock options or any other material amendment to the Plan may be made without the 
approval of the shareholders.

Market Price of the Company's Common Stock

     The closing market price of our common stock as reported on the New York Stock Exchange for April 18, 2016 was $22.17 
per share.

Estimate of Benefits

Generally, awards under the Plan are subject to the discretion of the Committee, and no determination has been made as 
to the types or amounts of awards that will be granted in the future to specific individuals pursuant to the Plan.  Therefore, it is 
not possible to determine the future benefits that will be received by all potential participants.  However, for illustrative purposes, 
50,000 options were granted to 17 employees under the Plan during the fiscal year ended December 31, 2015.

Although executive officers and members of our Board of Directors are eligible to receive awards under the Plan, since 

2006, awards under the Plan have been made exclusively to non-executive employees of the Company.

Dilution, Burn Rate and Overhang

We actively manage our long-term dilution by limiting the number of shares subject to equity awards that we grant 
annually, expressed as a percentage of weighted average common shares outstanding and referred to as burn rate. Burn rate is 
another measure of dilution that shows how rapidly a company is depleting its shares reserved for equity compensation plans and 
measures the potential dilutive effect of annual equity grants. Our burn rate for 2015 was 1.5%.

An additional metric that we use to measure the cumulative impact of our equity programs is overhang (number of shares 
subject to equity awards outstanding under our equity plans but not exercised or settled, plus number of shares available to be 
granted, divided by weighted average common shares outstanding plus available equity awards under our equity plans). Our 
overhang as of December 31, 2015 was 7.7%.  If the proposal to extend the Plan and increase the shares reserved for issuance 
under the plan by 250,000 shares is approved, our overhang as of that date would increase to 9.4% and then would be expected 
to decline over time.

The following are the factors that were material to the evaluation of the Compensation Committee and Board, with input 
from management, in determining acceptable and targeted levels of dilution: competitive data from relevant peer companies, the 
current and future accounting expense associated with the Company's equity award practices, and the influence of shareholder 
advisory firms. The Company's equity programs are revisited at least annually and assessed against these (and other) measures. 
We believe that the Company's burn rate and overhang (with or without the extension and additional shares requested under the 
Plan) are reasonable and reflect a prudent use of equity for compensation purposes.

Summary

We strongly believe the approval of the amended and restated Plan which extends the plan for an additional 10-year term 
and increases the number of authorized shares for issuance from 750,000 to 1,000,000 is essential to our continued success. Awards 
such as those provided under the Plan provide an important incentive for participants and will help us to attract, retain and motivate 
qualified individuals to serve on behalf of our company.

Vote Required

Approval of this proposal requires the affirmative vote of the holders of a majority of the shares casting votes in person 
or by proxy on this proposal at the Annual Meeting. The number of such affirmative votes must be at least a majority of the required 
quorum for the meeting.

53

Recommendation of the Board of Directors

The Board believes the proposed amendments to and restatement of the Plan are in the best interests of Natural Gas 
Services Group and its shareholders, as the availability of an adequate number of shares reserved for grant under the Plan and the 
other amended terms described above will assist in the recruitment and retention of the best available personnel.

The Board of Directions of Natural Gas Services Group recommends a vote "FOR" the proposal to amend and 
restate the Stock Option Plan, a copy which is included in this Proxy Statement as Appendix A. Proxies received by the 
Board of Directors will be so voted unless shareholders specify in their proxies a contrary choice.

PROPOSAL 4 – RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING 
FIRM

We are asking the shareholders to ratify the Audit Committee’s appointment of BDO USA, LLP as our independent 
registered public accounting firm for the fiscal year ending December 31, 2016.  BDO USA, LLP is a registered public accounting 
firm with the Public Company Accounting Oversight Board (“PCAOB”), as required by the Sarbanes-Oxley Act of 2002 and the 
rules of the PCAOB.  Shareholder ratification of the appointment is not required under the laws of the State of Colorado, but the 
Board believes it is important to allow the shareholder to vote on the proposal.  In the event the shareholders fail to ratify the 
appointment, the Audit Committee will reconsider this appointment.  Even if the appointment is ratified, the Audit Committee, in 
its discretion, may direct the appointment of different independent registered public accounting firm at any time during the year 
if the Audit Committee determines that such a change would be in our best interests and that of our shareholders.

BDO USA, LLP representatives are expected to attend the 2016 Annual Meeting in person. They will have an opportunity 

to make a statement if they desire to do so and will be available to respond to appropriate shareholder questions.

Principal Accountant Fees

Our principal accountant for the fiscal years ended December 31, 2013, 2014 and 2015 was BDO USA, LLP.

Audit Fees

The aggregate fees billed for professional services rendered by BDO USA, LLP for the audit of our financial statements 
for our fiscal years ended December 31, 2014 and 2015 and the review of the financial statements on Forms 10-Q for the fiscal 
quarters in such fiscal years were approximately $236,000 and $273,916, respectively.

Audit Related Fees

During the years ended December 31, 2014 and 2015, there were no audit related fees.  

Tax Fees

We were not billed any tax fees by BDO USA, LLP  during the years ended December 31, 2014 or 2015.

All Other Fees

No other fees were billed by BDO USA, LLP, during our fiscal years ended December 31, 2014 and 2015, other than as 

described above.

Audit Committee Pre-Approval Policies and Procedures

As of the date of this proxy statement, our Audit Committee has not established general pre-approval policies and as 
of December 31, 2015, 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.

Certain rules of the Securities and Exchange Commission provide that an auditor is not independent of an audit client 
if the services it provides to the client are not appropriately approved, subject, however, to a de minimus exception contained in 
the rules.  The Audit Committee pre-approved all services provided by BDO USA, LLP in 2015 and the de minimus exception 
was not used.

The Board of Directors recommends that the shareholders vote “FOR” the ratification of the appointment of BDO USA, 
LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2016.

PROPOSAL 5 - CONSIDERATION OF AN AMENDMENT TO THE COMPANY’S BYLAWS TO IMPLEMENT A 
MAJORITY VOTING STANDARD IN UNCONTESTED ELECTIONS OF DIRECTORS

Background

The Company has received a proxy statement proposal from a shareholder under Securities and Exchange Commission 
Rule 14a-8 requesting that a proposal be included in this Proxy Statement which would require the Board of Directors to initiate 
the appropriate process to provide that director nominees be elected by the affirmative vote the majority votes cast at an annual 
meeting in connection with uncontested elections.  For reasons set forth below, and consistent with recent corporate governance 
initiatives described in this proxy statement, the Board of Directors agreed with the request and has initiated the process.  

Amendment

The Board of Directors has adopted and recommends that shareholders approve an amendment (the “Amendment”) to 
the Company’s Bylaws to implement a majority voting standard for the election of directors in uncontested elections.  A copy of 
the proposed amendment to the Bylaws is attached as Appendix B to this Proxy Statement. 

Implementation and Purpose of the Amendment

Section 7-107-209 of the Colorado Business Corporation Act (the “Act”) and the Company's Bylaws provide that directors 
are elected by a plurality of the votes cast by the shares entitled to vote in the election at a meeting in which a quorum is present.  
Under plurality voting, director nominees receiving the greatest number of votes “for” election (although not necessarily a majority) 
are elected as directors.

Section 7-107-208 of the Act provides that a Colorado corporation may impose a greater voting requirement for the 
election of directors, if authorized by its articles of incorporation or, if authorized by the articles of incorporation, through bylaws 
adopted by the shareholders.  The Company's Articles of Incorporation provide that the Bylaws may provide for a greater voting 
requirement as long as such Bylaws are adopted by the Company's shareholders. 

Considering the foregoing, the Board of Directors has amended Section 10 of Article II of the Bylaws to provide for a 
majority voting standard in uncontested director elections.  Under the new majority voting standard, a nominee for director in an 
uncontested election shall be elected to the Board if the votes cast for such nominee’s election exceed the votes cast against such 
nominee’s election.  For this purpose, abstentions and broker non-votes will not count as votes cast.  Directors will continue to be 
elected by plurality vote at any meeting of shareholders where the number of director nominees exceeds the number of directors 
to be elected, commonly referred to as a contested election. In the event a director fails to receive a majority of the votes cast in 
an uncontested election, the Board of Directors may, within its powers, decrease the number of directors, fill the vacancy, or take 
other appropriate action.

The transition from plurality voting to majority voting in the election of Directors is a current trend in corporate governance, 
with a significant majority of the companies in the S&P 500 having adopted the majority vote standard.  By requiring that a Director 
nominee receive a majority of the votes cast (excluding abstentions and broker non-votes) in favor of his or her election to the 
Board of Directors, shareholders are provided with a more meaningful role in the election of Directors.  Under the Company's 
current plurality voting standard in connection with uncontested elections, a nominee for the Board can be elected with as little 
as a single affirmative vote, because withheld votes have no effect.  

If this proposal is approved by our shareholders, the Board of Directors will revise its director resignation policy to 
provide that any incumbent director who does not receive a majority of the votes cast is required to tender his or her resignation.  

The Board continues to believe that the plurality vote standard should continue to apply in contested director elections. 
If a majority vote standard is used in a contested election, fewer candidates could be elected to the Board than the number of 
authorized board seats if too many directors receive more “against” than “for” votes. Therefore, the Amendment retains plurality 
voting in contested director elections.

56

 
 
 
 
 
 
   
Vote Required

Approval of this proposal requires the affirmative vote of the holders of a majority of the shares casting votes in person 
or by proxy on this proposal at the Annual Meeting. The number of such affirmative votes must be at least a majority of the required 
quorum for the meeting.

Effective Date

If approved by the Company’s shareholders, the Amendment will become immediately effective.  The new majority 
voting  standard  would  then  be  applicable  to  an  uncontested  election  of  directors  at  the  Company’s  2017  annual  meeting  of 
shareholders.

Our Board of Directors recommends a vote "FOR" approval of the amendment to the Bylaws to implement a majority 
voting standard in uncontested elections of Directors.

57

 
 
SHAREHOLDER PROPOSALS

Under SEC Rule 14a-8, if a shareholder wants us to include a proposal in our proxy statement and form of proxy for 
presentation at our 2017 Annual Meeting of Shareholders, the proposal must be received by us at our principal executive offices 
at 508 West Wall Street, Suite 550, Midland, Texas 79701 by December 19, 2016, unless the date of our 2017 Annual Meeting of 
Shareholders is more than 30 days from the anniversary date of our 2016 Annual Meeting of Shareholders, in which case the 
deadline is a reasonable time before we print and mail our proxy materials for the 2017 Annual Meeting of Shareholders.  The 
proposal should be sent to the attention of the Secretary of Natural Gas Services Group.

Rule 14a-4 of the SEC's proxy rules allows a company to use discretionary voting authority to vote on matters coming 
before an annual meeting of shareholders for the prior year's annual meeting of shareholders or the date specified by an overriding 
advance notice provision in the company's bylaws. Our bylaws do not contain such an advance notice provision. Accordingly, for 
our 2017 annual meeting, shareholders' written notices must be received by us before March 9, 2017 for any proposal a shareholder 
wishes to bring before the meeting but for which such shareholder does not seek to have a written proposal considered for inclusion 
in the proxy statement and form of proxy. Your notice should be addressed to President, Natural Gas Services Group, Inc., 508 
West Wall Street, Suite 550, Midland, Texas 79701.

In order to curtail controversy as to the date on which a proposal was received by us, it is suggested that proponents 
submit their proposals by certified mail-return receipt requested.  Such proposals must also meet the other requirements established 
by the SEC for shareholder proposals.

58

 
 
COMMUNICATIONS WITH THE BOARD OF DIRECTORS

Because of our relatively small size, to date we have not developed formal processes by which shareholders or other 
interested parties may communicate directly with Directors.  Until formal procedures are developed and posted on our website 
(www.ngsgi.com), any communication to one or more members of our Board of Directors may be made by sending them in care 
of Investor Relations, Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701.  Shareholders 
should clearly note on the mailing envelope that the letter is a “Shareholder-Board Communication.”  All such communications 
will be forwarded to the intended recipients.

OTHER MATTERS

Our Board of Directors does not know of any matters to be presented at the meeting other than the matters set forth herein. 
If any other business should come before the meeting, the person’s named in the enclosed proxy card will vote such proxy according 
to their judgment on such matters.

New York Stock Exchange Certification. We listed our common stock on the New York Stock Exchange in October 
2008. The certification of our Chief Executive Officer required by the NYSE Listing Standards, Section 303A.12(a), relating to 
our compliance with the NYSE Corporate Governance Listing Standards, was submitted to the NYSE on June 4, 2015, in connection 
with our listing on the exchange. The certifications of our Chief Executive Officer and Principal Accounting Officer required by 
the SEC in connection with our Annual Report on Form 10-K for the year ended December 31, 2015, were submitted to the SEC 
on March 11, 2016, with our Annual Report on Form 10-K.

You may obtain our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, without charge upon

SEC under the Securities Exchange Act of 1934, as amended, including our proxy statements and reports filed by officers and 
directors under Section 16(a) of the Exchange Act, as well as our Code of Business Ethics and the charters to our various Committees 
of our Board of Directors.  We do not intend for information contained in our website to be part of this proxy statement.

year (under this Plan and all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such Options shall be treated

the date of grant of each Option and the determination of which Incentive Stock Options shall be treated as qualified incentive 
stock options under Section 422 of the Code and which Incentive Stock Options exercisable for the first time in a particular year 
in excess of the $100,000 limitation shall be treated as Nonstatutory Stock Options shall be determined based on the order in which

but unissued, or reacquired Common Stock. If an Option should expire or become unexercisable for any reason without having 
been exercised in full, the unpurchased Shares which were subject thereto shall, unless this Plan shall have been terminated, 
become available for future grant under this Plan.

4.   

Administration of this Plan.

a.   

Procedure.  This Plan shall be administered by the Board or a Committee appointed by the Board consisting of 
two or more Non-Employee Directors to administer this Plan on behalf of the Board, subject to such terms and conditions as the 
Board may prescribe.

(i)   

Once appointed, the Committee shall continue to serve until otherwise directed by the Board (which 
for purposes of this paragraph (a)(i) of this Section 4 shall be the Board of Directors of the Company). From time to time 
the Board may increase the size of the Committee and appoint additional members thereof, remove members (with or 
without cause) and appoint new members in substitution therefore, fill vacancies however caused, or remove all members 
of the Committee and thereafter directly administer this Plan.

(ii)     Members of the Board who are granted, or have been granted, Options may vote on any matters affecting 

the administration of this Plan or the grant of any Options pursuant to this Plan.

b. 

Powers of the Board.  Subject to the provisions of this Plan, the Board shall have the authority, in its discretion:

(i)     

To grant Incentive Stock Options, in accordance with Section 422 of the Code, and Nonstatutory Stock 
Options or both as provided and identified in a separate written Stock Option Agreement to each Optionee granted such 
Option or Options under this Plan; provided however, that in no event shall an Incentive Stock Option and a Nonstatutory 
Stock  Option  granted  to  any  Optionee  under  a  single  Stock  Option Agreement  be  subject  to  a  “tandem”  exercise 

 
 
 
 
 
 
 
 
 
 
 
 
 
Appendix A

arrangement such that the exercise of one such Option affects the Optionee’s right to exercise the other Option granted 
under such Stock Option Agreement;

(ii)      To determine, upon review of relevant information and in accordance with Section 8(b) of this Plan, 

the fair market value of the Common Stock;

(iii)     To  determine  the  exercise  price  per  Share  of  Options  to  be  granted,  which  exercise  price  shall  be 

determined in accordance with Section 8(a) of this Plan;

(iv)     To determine the Employees or other persons to whom, and the time or times at which, Options shall 

be granted and the number of Shares to be represented by each Option;

(v) 

To interpret this Plan;

(vi)       To prescribe, amend and rescind rules and regulations relating to this Plan;

(vii)      To determine the terms and provisions of each Option granted (which need not be identical) and, with 

the consent of the holder thereof, modify or amend each Option;

(viii)     To accelerate or defer (with the consent of the Optionee) the exercise date of any Option, consistent 

with the provisions of Section 7 of this Plan;

(ix)   

To authorize any person to execute on behalf of the Company any instrument required to effectuate the 

grant of an Option previously granted by the Board; and

(x)      To make all other determinations deemed necessary or advisable for the administration of this Plan.

c.    

Effect of Board’s Decision.  All decisions, determinations and interpretations of the Board shall be final and 

binding on all Optionees and any other permissible holders of any Options granted under this Plan.

5.   

Eligibility.

a.   

Persons Eligible.  Options may be granted to any person selected by the Board. Incentive Stock Options may 
be granted only to Employees.  An Employee, who is also a director of the Company, its Parent or a Subsidiary, shall be treated 
as an Employee for purposes of this Section 5.  An Employee or other person who has been granted an Option may, if he is otherwise 
eligible, be granted an additional Option or Options.

b.   

No Effect on Relationship.  This Plan shall not confer upon any Optionee any right with respect to continuation 
of employment or other relationship with the Company nor shall it interfere in any way with his right or the Company’s right to 
terminate his employment or other relationship at any time.

6.    
February 28, 2026, unless sooner terminated under Section 13 of this Plan.

Term of Plan.  This Plan, as amended and restated, became effective on March 1, 2016. It shall continue in effect until 

Term of Option.  The term of each Option shall be 10 years from the date of grant, thereof, or such shorter term as may 
7.    
be provided in the Stock Option Agreement. However, in the case of an Option granted to an Optionee who, at the time the Option 
is granted, owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or 
any Parent or Subsidiary, if the Option is an Incentive Stock Option, the term of the Option shall be five years from the date of 
grant thereof or such shorter time as may be provided in the Stock Option Agreement.

8.   

Exercise Price and Consideration.

a.   

Exercise Price.  The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall 
be such price as is determined by the Board, but the per Share exercise price under an Incentive Stock Option shall be subject to 
the following:

(i)    

If granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock 
representing more than 10% of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the 
per Share exercise price shall not be less than 110% of the fair market value per Share on the date of grant.

 
 
 
 
 
 
 
 
 
 
 
 
 
Appendix A

(ii)    

If granted to any other Employee, the per Share exercise price shall not be less than 100% of the fair 

market value per Share on the date of grant.

b.    

Determination of Fair Market Value.  The fair market value per Share on the date of grant shall be determined 

as follows:

(i)    

If the Common Stock is listed on the New York Stock Exchange, the American Stock Exchange or such 
other securities exchange designated by the Board, or admitted to unlisted trading privileges on any such exchange, or 
if the Common Stock is quoted on a National Association of Securities Dealers, Inc. system that reports closing prices, 
the fair market value shall be the closing price of the Common Stock as reported by such exchange or system on the day 
the fair market value is to be determined, or if no such price is reported for such day, then the determination of such 
closing price shall be as of the last immediately preceding day on which the closing price is so reported;

(ii)    

If the Common Stock is not so listed or admitted to unlisted trading privileges or so quoted, the fair 
market value shall be the average of the last reported highest bid and the lowest asked prices quoted on the National 
Association of Securities Dealers, Inc. Automated Quotations System or, if not so quoted, then by the National Quotation 
Bureau, Inc. on the day the fair market value is determined; or

(iii)   

If the Common Stock is not so listed or admitted to unlisted trading privileges or so quoted, and bid 
and asked prices are not reported, the fair market value shall be determined in such reasonable manner as may be prescribed 
by the Board.

c.    

Consideration and Method of Payment.  The consideration to be paid for the Shares to be issued upon exercise 
of an Option, including the method of payment, shall be determined by the Board and may consist entirely of cash, check, other 
shares of Common Stock having a fair market value on the date of exercise equal to the aggregate exercise price of the Shares as 
to which said Option shall be exercised, or any combination of such methods of payment, or such other consideration and method 
of payment for the issuance of Shares to the extent permitted under the Colorado Business Corporation Act.

9.   

Exercise of Option.

a.    

Procedure for Exercise: Rights as a Shareholder.  Any Option granted hereunder shall be exercisable at such 
times and under such conditions as determined by the Board, including performance criteria with respect to the Company and/or 
the Optionee, and as shall be permissible under the terms of this Plan.

An Option may not be exercised for a fraction of a Share.

An option shall be deemed to be exercised when written notice of such exercise has been given to the Company in 
accordance with the terms of the Stock Option Agreement by the person entitled to exercise the Option and full payment for the 
Shares with respect to which the Option is exercised has been received by the Company. Full payment, as authorized by the Board, 
may consist of a consideration and method of payment allowable under Section 8(c) and this Section 9(a) of this Plan. Until the 
issuance (as evidenced by the appropriate entry on the books of the Company or of the duly authorized transfer agent of the 
Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder 
shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a 
dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 
11 of this Plan.

Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, 

both for purposes of this Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

b.    

Termination of Status as an Employee.  In the case of an Incentive Stock Option, if any Employee ceases to 
serve as an Employee, he may, but only within such period of time not exceeding three months as is determined by the Board at 
the time of grant of the Option after the date he ceases to be an Employee of the Company, exercise his Option to the extent that 
he was entitled to exercise it at the date of such termination. To the extent that he was not entitled to exercise the Option at the 
date of such termination, or if he does not exercise such Option (which he was entitled to exercise) within the time specified herein, 
the Option shall terminate.

Disability of Optionee.  In the case of an Incentive Stock Option, notwithstanding the provisions of Section 9
(b) above, in the event an Employee is unable to continue his employment with the Company as a result of his total and permanent 

c.    

 
 
 
 
 
 
 
 
 
 
 
 
Appendix A

disability (as defined in Section 22(e)(3) of the Code), he may, but only within such period of time not exceeding 12 months as 
is determined by the Board at the time of grant of the Option from the date of termination, exercise his Option to the extent he 
was entitled to exercise it at the date of such termination. To the extent that he was not entitled to exercise the Option at the date 
of termination, or if he does not exercise such Option (which he was entitled to exercise) within the time specified herein, the 
Option shall terminate.

d.    

Death of Optionee.  In the case of an Incentive Stock Option, in the event of the death of the Optionee:

(i)  

During the term of the Option if the Optionee was at the time of his death an Employee and had been 
in Continuous Status as an Employee or Consultant since the date of grant of the Option, the Option may be exercised, 
at any time within 12 months following the date of death, by the Optionee’s estate or by a person who acquired the right 
to exercise the Option by bequest or inheritance, but only to the extent that the right to exercise would have accrued had 
the Optionee continued living and remained in Continuous Status as an Employee 12 months after the date of death; or

(ii)   Within such period of time not exceeding three months as is determined by the Board at the time of 
grant of the Option after the termination of Continuous Status as an Employee, the Option may be exercised, at any time 
within 12 months following the date of death, by the Optionee’s estate or by a person who acquired the right to exercise 
the Option by bequest or inheritance, but only to the extent that the right to exercise had accrued at the date of termination.

Nontransferability of Options.  Unless permitted by the Code, in the case of an Incentive Stock Option, the Option may 
10.   
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent 
and distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee.

11.   
Adjustments Upon Changes in Capitalization or Merger.  Subject to any required action by the shareholders of the 
Company, the number of Shares covered by each outstanding Option, and the number of Shares which have been authorized for 
issuance under this Plan but as to which no Options have yet been granted or which have been returned to this Plan upon cancellation 
or expiration of any Option, as well as the price per Share covered by each such outstanding Option, shall be proportionately 
adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, 
combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common 
Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities 
of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by 
the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no 
issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, 
and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option.

In the event of the proposed dissolution or liquidation of the Company, the Option will terminate immediately prior to 
the consummation of such proposed action, unless otherwise provided by the Board. The Board may, in the exercise of its sole 
discretion in such instances, declare that any Option shall terminate as of a date fixed by the Board and give each Optionee the 
right to exercise his Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise 
be exercisable. In the event of the proposed sale of all or substantially all of the assets of the Company, or the merger of the 
Company with or into another entity in a transaction in which the Company is not the survivor, the Option shall be assumed or an 
equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless 
the Board determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the Optionee shall 
have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise 
be exercisable. If the Board makes an Option fully exercisable in lieu of assumption or substitution in the event of such a merger 
or sale of assets, the Board shall notify the Optionee that the Option shall be fully exercisable for a period of 30 days from the 
date of such notice, and the Option will terminate upon the expiration of such period.

Time of Granting Options.  The date of grant of an Option shall, for all purposes, be the date on which the Board makes 
12.   
the determination granting such Option. Notice of the determination shall be given to each Employee or other person to whom an 
Option is so granted within a reasonable time after the date of such grant. Within a reasonable time after the date of the grant of 
an Option, the Company shall enter into and deliver to each Employee or other person granted such Option a written Stock Option 
Agreement  as  provided  in  Sections  2(r)  and  16  hereof,  setting  forth  the  terms  and  conditions  of  such  Option  and  separately 
identifying the portion of the Option which is an Incentive Stock Option and/or the portion of such Option which is a Nonstatutory 
Stock Option.

 
 
 
 
Appendix A

13.   

Amendment and Termination of this Plan.

a.    

Amendment and Termination.  The Board may amend or terminate this Plan from time to time in such respects 
as the Board may deem advisable; provided that, the following revisions or amendments shall require approval of the shareholders 
of the Company in the manner described in Section 17 of this Plan:

(i) 

Any change in the designation of the class of Employees eligible to be granted Incentive Stock Options; 

or

(ii)   

Any material amendment under this Plan that would have to be approved by the shareholders of the 

Company for the Board to continue to be able to grant Incentive Stock Options under this Plan.

b.    

Effect of Amendment or Termination.  Any such amendment or termination of this Plan shall not affect Options 
already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless 
mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee 
and the Company.

Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant to the exercise of an Option unless the exercise 
14.   
of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, 
including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the rules 
and regulations promulgated thereunder, applicable state securities laws, and the requirements of any stock exchange upon which 
the Shares may then be listed, and shall be further subject to the approval of legal counsel for the Company with respect to such 
compliance.

As a condition to the existence of an Option, the Company may require the person exercising such Option to represent 
and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present 
intention to sell or distribute such Shares and such other representations and warranties which in the opinion of legal counsel for 
the Company, are necessary or appropriate to establish an exemption from the registration requirements under applicable federal 
and state securities laws with respect to the acquisition of such Shares.

15.   
Reservation of Shares.  The Company, during the term of this Plan, will at all times reserve and keep available such 
number of Shares as shall be sufficient to satisfy the requirements of this Plan. Inability of the Company to obtain authority from 
any regulatory body having jurisdiction, which authority is deemed by the Company’s legal counsel to be necessary for the lawful 
issuance and sale of any Share hereunder, shall relieve the Company of any liability relating to the failure to issue or sell such 
Shares as to which such requisite authority shall not have been obtained.

Stock Option Agreement.  Each Option granted to an Employee or other persons shall be evidenced by a written Stock 

16.   
Option Agreement in such form as the Board shall approve.

Shareholder Approval.  Any restatement or amendment of this Plan shall be subject to approval by the shareholders of 
17.   
the Company if and when required by law or regulations of the New York Stock Exchange (or such other stock exchange or 
quotation system that shares of the Company's common stock may be traded or listed upon at the time.) 

Information to Optionees.  The Company shall provide to each Optionee, during the period for which such Optionee 
18.   
has one or more Options outstanding, copies of all annual reports and other information which are provided to all shareholders of 
the Company. The Company shall not be required to provide such information if the issuance of Options under this Plan is limited 
to key employees whose duties in connection with the Company assure their access to equivalent information.

Gender.  As used herein, the masculine, feminine and neuter genders shall be deemed to include the others in all cases 

19.   
where they would so apply.

Section 409A. Notwithstanding anything in this Plan to the contrary, the Plan and Options granted under the Plan are 
20. 
intended to be stock rights that do not provide for the deferral of compensation under Section 409A of the Code.  The Plan shall 
be interpreted to the fullest extent possible and shall be operated so as to comply with the requirements imposed by Section 409A 
of the Code such that Options do not provide for the deferral of compensation.  If any Plan provision or Option would result in 
the imposition of any additional tax or interest under Section 409A of the Code, the Company and the participant intend that the 
Plan provision or Option will be reformed to avoid imposition, to the extent possible, of such additional tax and interest, and no 

 
 
 
 
 
action taken by the Company to so comply with Section 409A of the Code shall be deemed to adversely affect the participant’s 
rights to an Option.

  CHOICE  OF  LAW. 

  ALL  QUESTIONS  CONCERNING  THE  CONSTRUCTION,  VALIDITY  AND 
21.  
INTERPRETATION OF THIS PLAN AND THE INSTRUMENTS EVIDENCING OPTIONS WILL BE GOVERNED BY THE 
INTERNAL LAW, AND NOT THE LAW OF CONFLICTS, OF THE STATE OF COLORADO.

ARTICLE 1

Offices.

     The principal office of the corporation shall be designated from time to time by the corporation 
and may be within or outside of Colorado.

     The corporation may have such other offices, either within or outside Colorado, as the board of 
directors may designate or as the business of the corporation may require from time to time.

     The registered office of the corporation required by the Colorado Business Corporation Act to 
be maintained in Colorado may be, but need not be, identical with the principal office, and the 
address of the registered office may be changed from time to time by the board of directors.

ARTICLE II

Shareholders

     Section 1. Annual Meeting. The annual meeting of the shareholders shall be held each year on 
a date and at a time fixed by the board of directors of the corporation (or by the chairman of the 
board or the president in the absence of action by the board of directors), for the purpose of electing 
directors and for the transaction of such other business as may come before the meeting. If the 
election of directors is not held on the day fixed as provided herein for any annual meeting of the 
shareholders, or any adjournment thereof, the board of directors shall cause the election to be held 
at a special meeting of the shareholders as soon thereafter as it may conveniently be held. If a 
shareholder intends to bring up items of business or nominate directors at any annual meeting, 
written notice of such intent must be received at the corporation’s principal executive offices not 
less than the number of days that is required from time to time under federal securities laws with 
respect to companies registered under the Securities Exchange Act of 1934.

     A shareholder may apply to the district court in the county in Colorado where the corporation’s 
principal office is located or, if the corporation has no principal office in Colorado, to the district 
court of the county in which the corporation’s registered office is located to seek an order that a 
shareholder meeting be held (i) if an annual meeting was not held within six months after the close 
of the corporation’s most recently ended fiscal year or fifteen months after its last annual meeting, 
whichever is earlier, or (ii) if the shareholder participated in a proper call of or proper demand for 
a special meeting and notice of the special meeting was not given within thirty days after the date 
of the call or the date the last of the demands necessary to require calling of the meeting was received 
by the corporation, or the special meeting was not held in accordance with the notice.

     Section 2. Special Meetings. Unless otherwise prescribed by statute, special meetings of the 
shareholders may be called for any purpose by the chairman of the board, by the president, by the 
1

secretary, by any one director or by the board of directors of the corporation. The president shall 
call a special meeting of the shareholders if the corporation receives one or more written demands 
for the meeting, stating the purpose or purposes for which it is to be held, signed and dated by 
holders of shares representing at least ten percent of all the votes entitled to be cast on any issue 
proposed to be considered at the meeting.

     Section 3. Place of Meeting. The board of directors may designate any place, either within or 
outside Colorado, as the place for any annual meeting or any special meeting called by the board 
of directors. A waiver of notice signed by all shareholders entitled to vote at a meeting may designate 
any place, either within or outside Colorado, as the place for such meeting. If no designation is 
made, or if a special meeting is called other than by the board of directors, the place of meeting 
shall be the principal office of the corporation.

     Section 4. Notice of Meeting. Written notice stating the place, date, and time of the meeting 
shall be given not less than ten nor more than sixty days before the date of the meeting, except that 
(i) if the number of authorized shares is to be increased, at least thirty days' notice shall be given, 
or (ii) any other longer notice period shall be given if required by the Colorado Business Corporation 
Act. Notice of a special meeting shall include a description of the purpose or purposes of the meeting 
and the business conducted at a special meeting shall be limited to such purpose or purposes. Notice 
of an annual meeting need not include a description of the purpose or purposes of the meeting except 
the  purpose  or  purposes  shall  be  stated  with  respect  to  (i) an  amendment  to  the  articles  of 
incorporation of the corporation, (ii) a merger or share exchange in which the corporation is a party 
and, with respect to a share exchange, in which the corporation’s shares will be acquired, (iii) a 
sale, lease, exchange or other disposition, other than in the usual and regular course of business, of 
all or substantially all of the property of the corporation or of another entity which this corporation 
controls, in each case with or without the goodwill, (iv) a dissolution of the corporation, or (v) any 
other purpose for which a statement of purpose is required by the Colorado Business Corporation 
Act. Notice shall be given personally or by mail, private carrier, telegraph, teletype, electronically 
transmitted facsimile or other form of wire or wireless communication by or at the direction of the 
chief executive officer, the president, the secretary, or the officer or persons calling the meeting, to 
each shareholder of record entitled to vote at such meeting. If mailed and if in a comprehensible 
form, such notice shall be deemed to be given and effective when deposited in the United States 
mail, addressed to the shareholder at his address as it appears in the corporation’s current record of 
shareholders, with postage prepaid. If notice is given other than by mail, and provided that such 
notice is in a comprehensible form, the notice is given and effective on the date received by the 
shareholder.

     If requested by the person or persons lawfully calling such meeting, the secretary shall give 
notice thereof at corporate expense. No notice need be sent to any shareholder if three successive 
notices mailed to the last known address of such shareholder have been returned as undeliverable 
until such time as another address for such shareholder is made known to the corporation by such 
shareholder. In order to be entitled to receive notice of any meeting, a shareholder shall advise the 
corporation  in  writing  of  any  change  in  such  shareholder’s  mailing  address  as  shown  on  the 
corporation’s books and records.

     When a meeting is adjourned to another date, time or place, notice need not be given of the new 
date, time or place if the new date, time or place of such meeting is announced before adjournment 

2

at the meeting at which the adjournment is taken. At the adjourned meeting the corporation may 
transact any business which may have been transacted at the original meeting. If the adjournment 
is for more than 120 days, or if a new record date is fixed for the adjourned meeting, a new notice 
of the adjourned meeting shall be given to each shareholder of record entitled to vote at the meeting 
as of the new record date.

     A shareholder may waive notice of a meeting before or after the time and date of the meeting 
by a writing signed by such shareholder. Such waiver shall be delivered to the corporation for filing 
with the corporate records. Further, by attending a meeting either in person or by proxy, a shareholder 
waives objection to lack of notice or defective notice of the meeting unless the shareholder objects 
at the beginning of the meeting to the holding of the meeting or the transaction of business at the 
meeting because of lack of notice or defective notice. By attending the meeting, the shareholder 
also  waives  any  objection  to  consideration  at  the  meeting  of  a  particular  matter  not  within  the 
purpose or purposes described in the meeting notice unless the shareholder objects to considering 
the matter when it is presented.

     Section 5.  Fixing  of  Record  Date.  For  the  purpose  of  determining  shareholders  entitled  to 
(i) notice  of  or  vote  at  any  meeting  of  shareholders  or  any  adjournment  thereof,  (ii)  receive 
distributions or share dividends, or (iii) demand a special meeting, or to make a determination of 
shareholders for any other proper purpose, the board of directors may fix a future date as the record 
date for any such determination of shareholders, such date in any case to be not more than seventy 
days, and, in case of a meeting of shareholders, not less than ten days, prior to the date on which 
the particular action requiring such determination of shareholders is to be taken. If no record date 
is fixed by the board of directors, the record date shall be the date on which notice of the meeting 
is mailed to shareholders, or the date on which the resolution of the board of directors providing 
for a distribution is adopted, as the case may be. When a determination of shareholders entitled to 
vote at any meeting of shareholders is made as provided in this Section, such determination shall 
apply to any adjournment thereof unless the board of directors fixes a new record date, which it 
must do if the meeting is adjourned to a date more than 120 days after the date fixed for the original 
meeting.

     Notwithstanding the above, the record date for determining the shareholders entitled to take 
action  without  a  meeting  or  entitled  to  be  given  notice  of  action  so  taken  shall  be  the  date  the 
corporation first receives a writing upon which the action is taken. The record date for determining 
shareholders entitled to demand a special meeting shall be the date of the earliest of any of the 
demands pursuant to which the meeting is called.

     Section 6. Voting Lists. The secretary shall make, at the earlier of ten days before each meeting 
of shareholders or two business days after notice of the meeting has been given, a complete list of 
the shareholders entitled to be given notice of such meeting or any adjournment thereof. The list 
shall be arranged by voting groups and within each voting group by class or series of shares, shall 
be in alphabetical order within each class or series, and shall show the address of and the number 
of shares of each class or series held by each shareholder. For the period beginning the earlier of 
ten days prior to the meeting or two business days after notice of the meeting is given and continuing 
through the meeting and any adjournment thereof, this list shall be kept on file at the principal office 
of the corporation, or at a place (which shall be identified in the notice) in the city where the meeting 

3

 
will  be  held.  Such  list  shall  be  available  for  inspection  on  written  demand  by  any  shareholder 
(including for the purpose of this Section 6 any holder of voting trust certificates) or his agent or 
attorney during regular business hours and during the period available for inspection. The original 
stock transfer books shall be prima facie evidence as to the shareholders entitled to examine such 
list or to vote at any meeting of shareholders.

     Any shareholder, his agent or attorney may copy the list during regular business hours and during 
the period it is available for inspection, provided (i) the shareholder has been a shareholder for at 
least three months immediately preceding the demand or holds at least five percent of all outstanding 
shares of any class of shares as of the date of the demand, (ii) the demand is made in good faith and 
for a purpose reasonably related to the demanding shareholder’s interest as a shareholder, (iii) the 
shareholder describes with reasonable particularity the purpose and the records the shareholder 
desires to inspect, (iv) the records are directly connected with the described purpose, and (v) the 
shareholder pays a reasonable charge covering the costs of labor and material for such copies, not 
to exceed the estimated cost of production and reproduction.

     Section 7. Recognition Procedure for Beneficial Owners. The board of directors may adopt 
by resolution a procedure whereby a shareholder of the corporation may certify in writing to the 
corporation that all or a portion of the shares registered in the name of such shareholder are held 
for the account of a specified person or persons. The resolution may set forth (i) the types of nominees 
to which it applies, (ii) the rights or privileges that the corporation will recognize in a beneficial 
owner, which may include rights and privileges other than voting, (iii) the form of certification and 
the information to be contained therein, (iv) if the certification is with respect to a record date, the 
time within which the certification must be received by the corporation, (v) the period for which 
the nominee’s use of the procedure is effective, and (vi) such other provisions with respect to the 
procedure as the board of directors deems necessary or desirable. Upon receipt by the corporation 
of a certificate complying with the procedure established by the board of directors, the persons 
specified in the certification shall be deemed, for the purpose or purposes set forth in the certification, 
to be the registered holders of the number of shares specified in place of the shareholder making 
the certification.

     Section 8. Quorum and Manner of Acting. A majority of the votes entitled to be cast on a 
matter by a voting group shall constitute a quorum of that voting group for action on the matter. If 
less than a majority of such votes are represented at a meeting, a majority of the votes so represented 
may adjourn the meeting from time to time without further notice, for a period not to exceed 120 days 
for any one adjournment. If a quorum is present at such adjourned meeting, any business may be 
transacted which might have been transacted at the meeting as originally noticed. The shareholders 
present  at  a  duly  organized  meeting  may  continue  to  transact  business  until  adjournment, 
notwithstanding the withdrawal of enough shareholders to leave less than a quorum, unless the 
meeting is adjourned and a new record date is set for the adjourned meeting.

     If a quorum exists, except as required by law or except as provided in the Articles of Incorporation, 
except as provided in Section 2 of Article III and except as provided in Section 3 of Article VIII, 
action on a matter other than the election of directors by a voting group is approved if the votes cast 
within the voting group favoring the action exceed the votes cast within the voting group opposing 
the action.

4

     Section 9. Proxies. At all meetings of shareholders, a shareholder may vote by proxy by signing 
an appointment form or similar writing, either personally or by his duly authorized attorney-in-fact. 
A shareholder may also appoint a proxy by transmitting or authorizing the transmission of a telegram, 
teletype, or other electronic transmission providing a written statement of the appointment to the 
proxy, a proxy solicitor, proxy support service organization, or other person duly authorized by the 
proxy  to  receive  appointments  as  agent  for  the  proxy,  or  to  the  corporation.  The  transmitted 
appointment shall set forth or be transmitted with written evidence from which it can be determined 
that  the  shareholder  transmitted  or  authorized  the  transmission  of  the  appointment.  The  proxy 
appointment form or similar writing shall be filed with the secretary of the corporation before or at 
the time of the meeting. The appointment of a proxy is effective when received by the corporation 
and is valid for eleven months unless a different period is expressly provided in the appointment 
form or similar writing.

     Any complete copy, including an electronically transmitted facsimile, of an appointment of a 
proxy may be substituted for or used in lieu of the original appointment for any purpose for which 
the original appointment could be used.

     Revocation of a proxy does not affect the right of the corporation to accept the proxy’s authority 
unless (i) the corporation had notice that the appointment was coupled with an interest and notice 
that such interest is extinguished is received by the secretary or other officer or agent authorized to 
tabulate votes before the proxy exercises his authority under the appointment, or (ii) other notice 
of the revocation of the appointment is received by the secretary or other officer or agent authorized 
to tabulate votes before the proxy exercises his authority under the appointment. Other notice of 
revocation  may,  in  the  discretion  of  the  corporation,  be  deemed  to  include  the  appearance  at  a 
shareholders’ meeting of the shareholder who granted the proxy and his voting in person on any 
matter subject to a vote at such meeting.

     The death or incapacity of the shareholder appointing a proxy does not affect the right of the 
corporation to accept the proxy’s authority unless notice of the death or incapacity is received by 
the secretary or other officer or agent authorized to tabulate votes before the proxy exercises his 
authority under the appointment.

     The corporation shall not be required to recognize an appointment made irrevocable if it has 
received a writing revoking the appointment signed by the shareholder (including a shareholder 
who is a successor to the shareholder who granted the proxy) either personally or by his attorney-
in-fact, notwithstanding that the revocation may be a breach of an obligation of the shareholder to 
another person not to revoke the appointment.

     Subject to Section 11 of Article II and any express limitation on the proxy’s authority appearing 
on the appointment form, the corporation is entitled to accept the proxy’s vote or other action as 
that of the shareholder making the appointment.

     Section 10. Voting of Shares. Each outstanding share, regardless of class shall be entitled to 
one  vote,  except  in  the  election  of  directors,  and  each  fractional  share  shall  be  entitled  to  a 
corresponding fractional vote on each matter submitted to a vote at a meeting of shareholders, except 
to the extent that the voting rights of the shares of any class or classes are limited or denied by the 
articles of incorporation as permitted by the Colorado Business Corporation Act. Cumulative voting 
shall not be permitted in the election of directors or for any other purpose.

5

Each record holder of stock shall be entitled to vote in the election of directors and shall 
have as many votes for each of the shares owned by him as there are directors to be elected and for 
whose election he has the right to vote.  Except as provided in Section 4 of Article III, each director 
shall be elected by the vote of the majority of the votes cast with respect to the director at any 
meeting for the election of directors at which a quorum is present; provided that if the number of 
director nominees exceeds the number of directors to be elected, the directors shall be elected by 
the vote of a plurality of the shares represented in person or by proxy at any such meeting and 
entitled to vote on the election of directors. For purposes of this section, a majority of the votes cast 
means that the number of shares voted “for” a director must exceed the number of votes cast “against” 
with respect to that director (with abstentions and broker non-votes not counted as either a vote 
"for" or "against" the nominee's election.  In the event a director fails to receive an affirmative 
majority of the votes cast in an election where the number of nominees is less than or equal to the 
number  of  directors  to  be  elected,  the  Board  of  Directors,  within  its  powers,  may  decrease  the 
number of directors, fill the vacancy, or take other appropriate action.

     Except as otherwise ordered by a court of competent jurisdiction upon a finding that the purpose 
of this Section would not be violated in the circumstances presented to the court, the shares of the 
corporation  are  not  entitled  to  be  voted  if  they  are  owned,  directly  or  indirectly,  by  a  second 
corporation, domestic or foreign, and the first corporation owns, directly or indirectly, a majority 
of the shares entitled to vote for directors of the second corporation except to the extent the second 
corporation holds the shares in a fiduciary capacity.

     Redeemable shares are not entitled to be voted after notice of redemption is mailed to the holders 
and a sum sufficient to redeem the shares has been deposited with a bank, trust company or other 
financial institution under an irrevocable obligation to pay the holders the redemption price on 
surrender of the shares.

     Section 11. Corporation’s Acceptance of Votes. If the name signed on a vote, consent, waiver, 
proxy appointment, or proxy appointment revocation corresponds to the name of a shareholder, the 
corporation, if acting in good faith, is entitled to accept the vote, consent, waiver, proxy appointment 
or proxy appointment revocation and give it effect as the act of the shareholder. If the name signed 
on a vote, consent, waiver, proxy appointment or proxy appointment revocation does not correspond 
to the name of a shareholder, the corporation, if acting in good faith, is nevertheless entitled to 
accept the vote, consent, waiver, proxy appointment or proxy appointment revocation and to give 
it effect as the act of the shareholder if:

     (i) the shareholder is an entity and the name signed purports to be that of an officer or agent of 
the entity; 

     (ii) the name signed purports to be that of an administrator, executor, guardian or conservator 
representing the shareholder and, if the corporation requests, evidence of fiduciary status acceptable 
to the corporation has been presented with respect to the vote, consent, waiver, proxy appointment 
or proxy appointment revocation;

     (iii) the name signed purports to be that of a receiver or trustee in bankruptcy of the shareholder 
and,  if  the  corporation  requests,  evidence  of  this  status  acceptable  to  the  corporation  has  been 
presented  with  respect  to  the  vote,  consent,  waiver,  proxy  appointment  or  proxy  appointment 
revocation;

6

     (iv) the name signed purports to be that of a pledgee, beneficial owner or attorney-in-fact of the 
shareholder and, if the corporation requests, evidence acceptable to the corporation of the signatory’s 
authority to sign for the shareholder has been presented with respect to the vote, consent, waiver, 
proxy appointment or proxy appointment revocation;

     (v) two or more persons are the shareholder as co-tenants or fiduciaries and the name signed 
purports to be the name of at least one of the co-tenants or fiduciaries, and the person signing appears 
to be acting on behalf of all the co-tenants or fiduciaries; or

     (vi) the  acceptance  of  the  vote,  consent,  waiver,  proxy  appointment  or  proxy  appointment 
revocation is otherwise proper under rules established by the corporation that are not inconsistent 
with this Section 11.

     The  corporation  is  entitled  to  reject  a  vote,  consent,  waiver,  proxy  appointment  or  proxy 
appointment revocation if the secretary or other officer or agent authorized to tabulate votes, acting 
in good faith, has reasonable basis for doubt about the validity of the signature on it or about the 
signatory’s authority to sign for the shareholder.

     Neither the corporation nor its officers nor any agent who accepts or rejects a vote, consent, 
waiver, proxy appointment or proxy appointment revocation in good faith and in accordance with 
the standards of this Section is liable in damages for the consequences of the acceptance or rejection.

     Section 12. Meetings by Telecommunication. Any or all of the shareholders may participate 
in an annual or special shareholders’ meeting by, or the meeting may be conducted through the use 
of, any means of communication by which all persons participating in the meeting may hear each 
other during the meeting. A shareholder participating in a meeting by this means is deemed to be 
present in person at the meeting.

ARTICLE III

Board of Directors

     Section 1. General Powers. All corporate powers shall be exercised by or under the authority 
of, and the business and affairs of the corporation shall be managed under, the direction of its board 
of directors, except as otherwise provided in the Colorado Business Corporation Act or the articles 
of incorporation.

     Section 2. Number, Qualifications and Tenure. The business and affairs of the corporation 
shall be managed or be under the direction of the Board of Directors; and, subject to any restrictions 
imposed by law, by the Articles of Incorporation, or by these Bylaws, the Board of Directors may 
exercise all the powers of the corporation. The Board of Directors shall consist of three (3) members, 
unless otherwise determined from time to time by resolution adopted by at least 80% of the votes 
entitled to be cast by each voting group entitled to vote thereon, or by unanimous consent of the 
Board of Directors. No decrease shall affect the shortening of the term of any incumbent director. 
Directors need not be residents of Colorado or shareholders of the corporation absent provision to 
the contrary in the Articles of Incorporation or laws of the State of Colorado.

     Section 3. Removal of Directors. Any director or the entire Board of Directors may be removed 
from office, at any time, but only for cause, at any special meeting of shareholders by the affirmative 

7

vote of at least 80% of the votes entitled to be cast by each voting group entitled to vote thereon at 
such meeting, if notice of the intention to act upon such matter shall have been given in the notice 
calling such meeting. If the notice calling such meeting shall have so provided, the vacancy caused 
by such removal may be filled at such meeting by the affirmative vote of at least 80% of the shares 
of the votes entitled to be cast by each voting group entitled to vote thereon.

     Section 4.  Vacancies. Any  director  may  resign  at  any  time  by  giving  written  notice  to  the 
corporation. Such resignation shall take effect at the time the notice is received by the corporation 
unless  the  notice  specifies  a  later  effective  date.  Unless  otherwise  specified  in  the  notice  of 
resignation,  the  corporation’s  acceptance  of  such  resignation  shall  not  be  necessary  to  make  it 
effective. Any vacancy on the board of directors may be filled by the affirmative vote of a majority 
of the shareholders or the board of directors. If the directors remaining in office constitute fewer 
than a quorum of the board of directors, the directors may fill the vacancy by the affirmative vote 
of a majority of all the directors remaining in office. If elected by the directors, the director shall 
hold office until the next annual shareholders’ meeting at which directors are elected. If elected by 
the shareholders, the director shall hold office for the unexpired term of his predecessor in office; 
except that, if the directors’ predecessor was elected by the directors to fill a vacancy, the director 
elected by the shareholders shall hold office for the unexpired term of the last predecessor elected 
by the shareholders.

     Section 5. Regular Meetings. A regular meeting of the board of directors shall be held without 
notice immediately after and at the same place as the annual meeting of shareholders. The board of 
directors may provide by resolution the time and place, either within or outside Colorado, for the 
holding of additional regular meetings without other notice.

     Section 6. Special Meetings. Special meetings of the board of directors may be called by or at 
the request of the chairman of the board, the president or any two directors. The person or persons 
authorized to call special meetings of the board of directors may fix any place, either within or 
outside Colorado, as the place for holding any special meeting of the board of directors called by 
them.

     Section 7. Notice. Notice of any special meeting shall be given at least two days prior to the 
meeting by written notice either personally delivered or mailed to each director at his business 
address, or by notice transmitted by telegraph, telex, electronically transmitted facsimile or other 
form of wire or wireless communication. If mailed, such notice shall be deemed to be given and to 
be effective on the earlier of (i) three days after such notice is deposited in the United States mail, 
properly addressed, with postage prepaid, or (ii) the date shown on the return receipt, if mailed by 
registered  or  certified  mail  return  receipt  requested.  If  notice  is  given  by  telex,  electronically 
transmitted facsimile or other similar form of wire or wireless communication, such notice shall be 
deemed to be given and to be effective when sent and with respect to a telegram, such notice shall 
be deemed to be given and to be effective when the telegram is delivered to the telegraph company. 
If a director has designated in writing one or more reasonable addresses or facsimile numbers for 
delivery of notice to him, notice sent by mail, telegraph, telex, electronically transmitted facsimile 
or other form of wire or wireless communication shall not be deemed to have been given or to be 
effective unless sent to such addresses or facsimile numbers, as the case may be.

8

     A director may waive notice of a meeting before or after the time and date of the meeting by a 
writing signed by such director. Such waiver shall be delivered to the corporation for filing with 
the corporate records. Further, a director’s attendance at or participation in a meeting waives any 
required notice to him of the meeting unless at the beginning of the meeting, or promptly upon his 
later arrival, the director objects to holding the meeting or transacting business at the meeting because 
of lack of notice or defective notice and does not thereafter vote for or assent to action taken at the 
meeting. Neither the business to be transacted at, nor the purpose of, any regular or special meeting 
of the board of directors need be specified in the notice or waiver of notice of such meeting.

     Section 8. Quorum. A majority of the number of directors fixed pursuant to Section 2 of this 
Article III shall constitute a quorum for the transaction of business at any meeting of the board of 
directors.

     If less than such majority is present at a meeting, a majority of the directors present may adjourn 
the meeting from time to time without further notice, for a period not to exceed sixty days at any 
one adjournment.

     Section 9. Manner of Acting. Unless otherwise specified herein, the act of the majority of the 
directors present at a meeting at which a quorum is present shall be the act of the board of directors.

     Section l0. Compensation. By resolution of the board of directors, any director may be paid 
any one or more of the following: his expenses, if any, of attendance at meetings, a fixed sum for 
attendance at each meeting, a stated salary as director, or such other compensation as the board of 
directors and the director may reasonably agree upon. No such payment shall preclude any director 
from serving the corporation in any other capacity and receiving compensation therefor.

     Section 11. Presumption of Assent. A director of the corporation who is present at a meeting 
of the board of directors or committee of the board of directors at which action on any corporate 
matter is taken shall be presumed to have assented to the action taken unless (i) the director objects 
at the beginning of the meeting, or promptly upon his later arrival, to the holding of the meeting or 
the transaction of business at the meeting and does not thereafter vote for or assent to any action 
taken at the meeting, (ii) the director contemporaneously requests that his dissent or abstention as 
to any specific action taken be entered in the minutes of the meeting, or (iii) the director causes 
written notice of his dissent or abstention as to any specific action to be received by the presiding 
officer of the meeting before its adjournment or by the corporation promptly after the adjournment 
of the meeting. A director may dissent to a specific action at a meeting, while assenting to others. 
The right to dissent to a specific action taken at a meeting of the board of directors or a committee 
of the board of directors shall not be available to a director who voted in favor of such action.

     Section 12. Committees. By resolution adopted by a majority of all the directors in office when 
the action is taken, the board of directors may designate from among its members an executive 
committee and one or more other committees, and appoint one or more members of the board of 
directors to serve on them. To the extent provided in the resolution, each committee shall have all 
the - authority of the board of directors, except that no such committee shall have the authority to 
(i) authorize distributions, (ii) approve or propose to shareholders actions or proposals required by 
the Colorado Business Corporation Act to be approved by shareholders, (iii) fill vacancies on the 
board of directors or any committee thereof, (iv) amend articles of incorporation, (v) adopt, amend 
or repeal the bylaws, (vi) approve a plan of merger not requiring shareholder approval, (vii) authorize 

9

or approve the reacquisition of shares unless pursuant to a formula or method prescribed by the 
board of directors, or (viii) authorize or approve the issuance or sale of shares, or contract for the 
sale of shares or determine the designations and relative rights, preferences and limitations of a 
class or series of shares, except that the board of directors may authorize a committee or officer to 
do so within limits specifically prescribed by the board of directors. The committee shall then have 
full power within the limits set by the board of directors to adopt any final resolution setting forth 
all preferences, limitations and relative rights of such class or series and to authorize an amendment 
of the articles of incorporation stating the preferences, limitations and relative rights of a class or 
series for filing with the Secretary of State under the Colorado Business Corporation Act.

     Sections 5, 6, 7, 8 and 13 of Article III, which govern meetings, notice, waiver of notice, quorum, 
voting requirements and action without a meeting of the board of directors, shall apply to committees 
and their members appointed under this Section 12.

     Neither the designation of any such committee, the delegation of authority to such committee, 
nor any action by such committee pursuant to its authority shall alone constitute compliance by any 
member of the board of directors or a member of the committee in question with his responsibility 
to conform to the standard of care set forth in Article III Section 15 of these bylaws. 

     Section 13. Informal Action by Directors. Any action required or permitted to be taken at a 
meeting of the directors or any committee designated by the board of directors may be taken without 
a meeting if a written consent (or counterparts thereof) that sets forth the action so taken is signed 
by all of the directors or committee members entitled to vote with respect to the action taken. Such 
consent shall have the same force and effect as a unanimous vote of the directors or committee 
members  and  may  be  stated  as  such  in  any  document.  Unless  the  consent  specifies  a  different 
effective date, action taken under this Section 13 is effective at the time the last director signs a 
writing describing the action taken, unless, before such time, any director has revoked his consent 
by a writing signed by the director and received by the president or the secretary of the corporation.

     Section 14.  Telephonic  Meetings.  The  board  of  directors  may  permit  any  director  (or  any 
member of a committee designated by the board of directors) to participate in a regular or special 
meeting  of  the  board  of  directors  or  a  committee  thereof  through  the  use  of  any  means  of 
communication by which all directors participating in the meeting can hear each other during the 
meeting. A director participating in a meeting in this manner is deemed to be present in person at 
the meeting.

     Section 15. Standard of Care. A director shall perform his duties as a director, including without 
limitation his duties as a member of any committee of the board of directors, in good faith, in a 
manner he reasonably believes to be in the best interests of the corporation, and with the care an 
ordinarily  prudent  person  in  a  like  position  would  exercise  under  similar  circumstances.  In 
performing  his  duties,  a  director  shall  be  entitled  to  rely  on  information,  opinions,  reports  or 
statements, including financial statements and other financial data, in each case prepared or presented 
by the persons herein designated. However, he shall not be considered to be acting in good faith if 
he  has  knowledge  concerning  the  matter  in  question  that  would  cause  such  reliance  to  be 
unwarranted. A director shall not be liable to the corporation or its shareholders for any action he 
takes or omits to take as a director if, in connection with such action or omission, he performs his 
duties in compliance with this Section 15.

10

     The designated persons on whom a director is entitled to rely are (i) one or more officers or 
employees of the corporation whom the director reasonably believes to be reliable and competent 
in the matters presented, (ii) legal counsel, public accountant, or other person as to matters which 
the director reasonably believes to be within such person’s professional or expert competence, or 
(iii) a  committee  of  the  board  of  directors  on  which  the  director  does  not  serve  if  the  director 
reasonably believes the committee merits confidence.

ARTICLE IV

Officers and Agents

     Section 1. General. The officers of the corporation shall be a chief executive officer, a president, 
a secretary and a treasurer, each of whom shall be a natural person eighteen years of age or older. 
The board of directors or an officer or officers authorized by the board of directors may appoint 
such  other officers, assistant  officers, committees and  agents,  assistant secretaries and  assistant 
treasurers, as they may consider necessary. The board of directors or the officer or officers authorized 
by the board of directors shall from time to time determine the procedure for the appointment of 
officers, their term of office, their authority and duties and their compensation. One person may 
hold more than one office. In all cases where the duties of any officer, agent or employee are not 
prescribed by the bylaws or by the board of directors, such officer, agent or employee shall follow 
the orders and instructions of the president of the corporation.

     Section 2. Appointment and Term of Office. The officers of the corporation shall be appointed 
by the board of directors at each annual meeting of the board of directors held after each annual 
meeting of the shareholders. If the appointment of officers is not made at such meeting or if an 
officer  or  officers  are  to  be  appointed  by  another  officer  or  officers  of  the  corporation,  such 
appointments shall be made as soon thereafter as conveniently possible. Each officer shall hold 
office  until  the  first  of  the  following  occurs:  his  successor  shall  have  been  duly  appointed  and 
qualified, his death, his resignation, or his removal in the manner provided in Article IV, Section 3.

     Section 3. Resignation and Removal. An officer may resign at any time by giving written notice 
of resignation to the corporation. The resignation is effective when the notice is received by the 
corporation unless the notice specifies a later effective date.

     Any officer or agent may be removed at any time with or without cause by the board of directors 
or an officer or officers authorized by the board of directors or by the shareholders. Such removal 
does  not  affect  the  contract  rights,  if  any,  of  the  corporation  or  of  the  person  so  removed. The 
appointment of an officer or agent shall not in itself create contract rights.

     Section 4. Vacancies. A vacancy in any office, however occurring, may be filled by the board 
of directors, or by the officer or officers authorized by the board of directors, for the unexpired 
portion of the officer’s term. If an officer resigns and his resignation is made effective at a later 
date, the board of directors, or officer or officers authorized by the board of directors, may permit 
the officer to remain in office until the effective date and may fill the pending vacancy before the 
effective date if the board of directors or officer or officers authorized by the board of directors 
provide that the successor shall not take office until the effective date. In the alternative, the board 
of directors, or officer or officers authorized by the board of directors, may remove the officer at 
any time before the effective date and may fill the resulting vacancy.

11

     Section 5. Chairman of the Board. The chairman of the board of directors, if appointed and if 
available, or if not appointed or not available, the chief executive officer, or if not appointed or not 
available, the president, shall preside at all meetings of the stockholders and of the board of directors.

ARTICLE V

Stock

     Section 1. Certificates. The board of directors shall be authorized to issue any of its classes of 
shares with or without certificates, provided that the board of directors may provide by resolution 
or resolutions that some or all of any or all classes or series of the corporation’s stock shall be 
uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until 
such certificate is surrendered to the corporation. Notwithstanding the adoption of such a resolution 
by the board of directors, every holder of stock represented by a certificate or certificates and upon 
request every holder of uncertificated shares shall be entitled to have a certificate or certificates 
representing the number of shares of stock owned by him in the corporation registered in certificate 
form. If the shares are represented by certificates, such shares shall be represented by consecutively 
numbered certificates signed, either manually or by facsimile, in the name of the corporation by 
the chief executive officer or the president and by the secretary or by one or more other persons 
designated by the board of directors. In case any officer who has signed or whose facsimile signature 
has been placed upon such certificate shall have ceased to be such officer before such certificate is 
issued, such certificate may nonetheless be issued by the corporation with the same effect as if he 
were such officer at the date of its issue. Certificates of stock shall be in such form and shall contain 
such information consistent with the law as shall be prescribed by the board of directors. If shares 
are not represented by certificates, within a reasonable time following the issue or transfer of such 
shares,  the  corporation  shall  send  the  shareholder  a  complete  written  statement  of  all  of  the 
information required to be provided to holders of uncertificated shares by the Colorado Business 
Corporation Act. Except as otherwise provided by law, the rights and obligations of holders of 
uncertificated shares and the rights and obligations of the holders of certificated shares of the same 
class and series shall be identical.

     Section 2. Consideration for Shares. Certificated or uncertificated shares shall not be issued 
until the shares represented thereby are fully paid. The board of directors may authorize the issuance 
of certificated or uncertificated shares for consideration consisting of any tangible or intangible 
property of benefit to the corporation, including cash, promissory notes, services performed or other 
securities of the corporation. Future services shall not constitute payment or partial payment for 
shares of the corporation. The promissory note of a subscriber or an affiliate of a subscriber shall 
not constitute payment or partial payment for shares of the corporation unless the note is negotiable 
and is secured by collateral, other than the shares being purchased, having a fair market value at 
least equal to the principal amount of the note. For purposes of this Section 2, “promissory note” 
means a negotiable instrument on which there is an obligation to pay independent of collateral and 
does not include a non-recourse note.

     Section 3. Lost Certificates. In case of the alleged loss, destruction or mutilation of a certificate 
of  stock,  the  board  of  directors  may  direct  the  issuance  of  a  new  certificate  or  may  register 
uncertificated shares in lieu thereof upon such terms and conditions in conformity with law as the 
board of directors may prescribe. The board of directors may in its discretion require an affidavit 
of lost certificate and/or a bond in such form and amount and with such surety as it may determine 
before issuing a new certificate or registering uncertificated shares.

14

     Section 4.  Transfer  of  Shares.  Transfer  of  shares  shall  be  made  only  on  the  books  of  the 
corporation by the registered holder thereof, or by such holder’s attorney thereunto authorized by 
power of attorney and filed with the Secretary of the corporation or a transfer agent of the corporation. 
If  such  shares  are  certificated,  upon  surrender  to  the  corporation  or  to  a  transfer  agent  of  the 
corporation of a certificate of stock duly endorsed or accompanied by proper evidence of succession, 
assignment or authority to transfer, and receipt of such documentary stamps as may be required by 
law  and  evidence  of  compliance  with  all  applicable  securities  laws  and  other  restrictions,  the 
corporation shall issue a new certificate or register uncertificated shares to the person entitled thereto, 
and cancel the old certificate. Upon the receipt of proper transfer instructions of uncertificated shares 
by the holders thereof in person or by their duly authorized attorney, such uncertificated shares shall 
be  cancelled  and  the  corporation  shall  issue  new  equivalent  certificated  shares  or  register 
uncertificated  shares  to  the  person  entitled  thereto.  Every  such  transfer  of  certificated  or 
uncertificated shares shall be entered on the stock books of the corporation which shall be kept at 
its principal office or by the person and the place designated by the board of directors.

     Except  as  otherwise  expressly  provided  in Article II,  Sections 7  and  11,  and  except  for  the 
assertion  of  dissenters’  rights  to  the  extent  provided  in Article 113  of  the  Colorado  Business 
Corporation Act, the corporation shall be entitled to treat the registered holder of any shares of the 
corporation as the owner thereof for all purposes, and the corporation shall not be bound to recognize 
any equitable or other claim to, or interest in, such shares or rights deriving from such shares on 
the part of any person other than the registered holder, including without limitation any purchaser, 
assignee or transferee of such shares or rights deriving from such shares, unless and until such other 
person becomes the registered holder of such shares, whether or not the corporation shall have either 
actual or constructive notice of the claimed interest of such other person.

     Section 5. Transfer Agent, Registrars and Paying Agents. The board of directors may at its 
discretion appoint one or more transfer agents, registrars and agents for making payment upon any 
class of stock, bond, debenture or other security of the corporation. Such agents and registrars may 
be located either within or outside Colorado. They shall have such rights and duties and shall be 
entitled to such compensation as may be agreed.

ARTICLE VI

Indemnification of Certain Persons

     Section 1. Indemnification. For purposes of Article VI, a “Proper Person” means any person 
who was or is a party or is threatened to be made a party to any threatened, pending, or completed 
action,  suit  or  proceeding,  whether  civil,  criminal,  administrative  or  investigative,  and  whether 
formal or informal, by reason of the fact that he is or was a director, officer, employee, fiduciary or 
agent of the corporation, or is or was serving at the request of the corporation as a director, officer, 
partner,  trustee,  employee,  fiduciary  or  agent  of  any  foreign  or  domestic  profit  or  nonprofit 
corporation or of any partnership, joint venture, trust, profit or nonprofit unincorporated association, 
limited  liability  company,  or  other  enterprise  or  employee  benefit  plan.  The  corporation  shall 
indemnify  any  Proper  Person  against  reasonably  incurred  expenses  (including  attorneys’  fees), 
judgments, penalties, fines (including any excise tax assessed with respect to an employee benefit 
plan) and amounts paid in settlement reasonably incurred by him in connection with such action, 

15

suit or proceeding if it is determined by the groups set forth in Section 4 of this Article VI that he 
conducted himself in good faith and that he reasonably believed (i) in the case of conduct in his 
official capacity with the corporation, that his conduct was in the corporation’s best interests, or 
(ii) in  all  other  cases  (except  criminal  cases),  that  his  conduct  was  at  least  not  opposed  to  the 
corporation’s best interests, or (iii) in the case of any criminal proceeding, that he had no reasonable 
cause to believe his conduct was unlawful. A Proper Person will be deemed to be acting in his 
official capacity while acting as a director, officer, employee or agent on behalf of this corporation 
and not while acting on this corporation’s behalf for some other entity.

     No indemnification shall be made under this Article VI to a Proper Person with respect to any 
claim, issue or matter in connection with a proceeding by or in the right of a corporation in which 
the Proper Person was adjudged liable to the corporation or in connection with any proceeding 
charging that the Proper Person derived an improper personal benefit, whether or not involving 
action in an official capacity, in which he was adjudged liable on the basis that he derived an improper 
personal  benefit.  Further,  indemnification  under  this  Section  in  connection  with  a  proceeding 
brought by or in the right of the corporation shall be limited to reasonable expenses, including 
attorneys’ fees, incurred in connection with the proceeding.

     Section 2. Right to Indemnification. The corporation shall indemnify any Proper Person who 
was wholly successful, on the merits or otherwise, in defense of any action, suit, or proceeding as 
to which he was entitled to indemnification under Section 1 of this Article VI against expenses 
(including attorneys’ fees) reasonably incurred by him in connection with the proceeding without 
the necessity of any action by the corporation other than the determination in good faith that the 
defense has been wholly successful.

     Section 3. Effect of Termination of Action. The termination of any action, suit or proceeding 
by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent 
shall not of itself create a presumption that the person seeking indemnification did not meet the 
standards of conduct described in Section 1 of this Article VI. Entry of a judgment, by consent as 
part of a settlement shall not be deemed an adjudication of liability, as described in Section 2 of 
this Article VI.

     Section 4. Groups Authorized to Make Indemnification Determination. Except where there 
is a right to indemnification as set forth in Sections 1 or 2 of this Article VI or where indemnification 
is  ordered  by  a  court  in  Section 5  of  this Article VI,  any  indemnification  shall  be  made  by  the 
corporation only as authorized in the specific case upon a determination by a proper group that 
indemnification of the Proper Person is permissible under the circumstances because he has met 
the applicable standards of conduct set forth in Section 1 of this Article VI. This determination shall 
be made by the board of directors by a majority vote of those present at a meeting at which a quorum 
is present, which quorum shall consist of directors not parties to the proceeding (“Quorum”). If a 
Quorum cannot be obtained, the determination shall be made by a majority vote of a committee of 
the board of directors designated by the board, which committee shall consist of two or more directors 
not parties to the proceeding, except that directors who are parties to the proceeding may participate 
in the designation of directors for the committee. If a Quorum of the board of directors cannot be 
obtained and the committee cannot be established, or even if a Quorum is obtained or the committee 
is designated and a majority of the directors constituting such Quorum or committee so directs, the 
determination shall be made by (i) independent legal counsel selected by a vote of the board of 

16

directors or the committee in the manner specified in this Section 4 or, if a Quorum of the full board 
of directors cannot be obtained and a committee cannot be established, by independent legal counsel 
selected by a majority vote of the fall board of directors (including directors who are parties to the 
action) or (ii) a vote of the shareholders.

     Section 5. Court-Ordered Indemnification. Any Proper Person may apply for indemnification 
to the court conducting the proceeding or to another court of competent jurisdiction for mandatory 
indemnification  under  Section 2  of  this  Article VI,  including  indemnification  for  reasonable 
expenses incurred to obtain court-ordered indemnification. If the court determines that such Proper 
Person is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, 
whether  or  not  he  met  the  standards  of  conduct  set  forth  in  Section 1  of  this Article VI  or  was 
adjudged liable in the proceeding, the court may order such indemnification as the court deems 
proper except that if the Proper Person has been adjudged liable, indemnification shall be limited 
to reasonable expenses incurred in connection with the proceeding and reasonable expenses incurred 
to obtain court-ordered indemnification.

     Section 6. Advance of Expenses. Reasonable expenses (including attorneys’ fees) incurred in 
defending an action, suit or proceeding as described in Section 1 of this Article VI may be paid by 
the corporation to any Proper Person in advance of the final disposition of such action, suit or 
proceeding upon receipt of (i) a written affirmation of such Proper Person’s good faith belief that 
he  has  met  the  standards  of  conduct  prescribed  by  Section 1  of  this Article VI,  (ii) a  written 
undertaking, executed personally or on the Proper Person’s behalf, to repay such advances if it is 
ultimately determined that he did not meet the prescribed standards of conduct (the undertaking 
shall be an unlimited general obligation of the Proper Person but need not be secured and may be 
accepted without reference to financial ability to make repayment), and (iii) a determination is made 
by the proper group (as described in Section 4 of this Article VI) that the facts as then known to the 
group would not preclude indemnification. Determination and authorization of payments shall be 
made in the same manner specified in Section 4 of this Article VI.

     Section 7. Witness  Expenses. The  sections  of  this Article VI  do  not  limit  the  corporation’s 
authority to pay or reimburse expenses incurred by a director in connection with an appearance as 
a witness in a proceeding at a time when he has not been made a named defendant or respondent 
in the proceeding.

     Section 8. Report to Shareholders. Any indemnification of or advance of expenses to a director 
in accordance with this Article VI, if arising out of a proceeding by or on behalf of the corporation, 
shall be reported in writing to the shareholders with or before the notice of the next shareholders’ 
meeting. If the next shareholder action is taken without a meeting at the instigation of the board of 
directors, such notice shall be given to the shareholders at or before the time the first shareholder 
signs a writing consenting to such action.

ARTICLE VII

Provision of Insurance

     By action of the board of directors, notwithstanding any interest of the directors in the action, 
the corporation may purchase and maintain insurance, in such scope and amounts as the board of 
directors deems appropriate, on behalf of any person who is or was a director, officer, employee, 
17

fiduciary or agent of the corporation, or who, while a director, officer, employee, fiduciary or agent 
of the corporation, is or was serving at the request of the corporation as a director, officer, partner, 
trustee,  employee,  fiduciary  or  agent  of  any  other  foreign  or  domestic  corporation  or  of  any 
partnership,  joint  venture,  trust,  profit  or  nonprofit  unincorporated  association,  limited  liability 
company or other enterprise or employee benefit plan, against any liability asserted against, or 
incurred by, him in that capacity or arising out of his status as such, whether or not the corporation 
would have the power to indemnify him against such liability under the provisions of Article VI or 
applicable law. Any such insurance may be procured from any insurance company designated by 
the board of directors of the corporation, whether such insurance company is formed under the laws 
of Colorado or any other jurisdiction of the United States or elsewhere, including any insurance 
company  in  which  the  corporation  has  an  equity  interest  or  any  other  interest,  through  stock 
ownership or otherwise.

ARTICLE VIII

Miscellaneous

     Section 1. Seal. The corporate seal of the corporation shall be circular in form and shall contain 
the name of the corporation and the words, “Seal, Colorado.”

     Section 2. Fiscal Year. The fiscal year of the corporation shall be as established by the board of 
directors.

     Section 3. Amendments. Except as hereinafter stated, the board of directors shall have power, 
to the maximum extent permitted by the Colorado Business Corporation Act, to make, amend and 
repeal the bylaws of the corporation at any regular or special meeting of the board of directors unless 
the shareholders, in making, amending or repealing a particular bylaw, expressly provide that the 
directors may not amend or repeal such bylaw. The directors may not amend Sections 2 or 3 of 
Article III, Article VI or Section 3 of Article VIII of the bylaws. Sections 2 and 3 of Article Ill, 
Article VI and Section 3 of Article VIII of the bylaws can only be amended or repealed by 80% of 
the votes of the shareholders entitled to be cast thereon. The shareholders also shall have the power 
to make, amend or repeal the bylaws of the corporation at any annual meeting or at any special 
meeting called for that purpose.

     Section 4. Gender. The masculine gender is used in these bylaws as a matter of convenience 
only and shall be interpreted to include the feminine and neuter genders as the circumstances indicate.

     Section 5. Conflicts. In the event of any irreconcilable conflict between these bylaws and either 
the corporation’s articles of incorporation or applicable law, the latter shall control. 

     Section 6. Definitions. Except as otherwise specifically provided in these bylaws, all terms used 
in these bylaws shall have the same definition as in the Colorado Business Corporation Act.

BUSINESS

PART I

Unless the context otherwise requires, references in this Annual Report on Form 10-K to “Natural Gas Services Group,” 
the “Company”, “we,” “us,” “our” or “ours” refer to Natural Gas Services Group, Inc.  Certain specialized terms used in describing 
our natural gas compressor business are defined in "Glossary of Industry Terms" on page 8.

The Company

We are a leading provider of small to medium horsepower compression equipment to the natural gas industry.  We 
focus primarily on the non-conventional natural gas and oil production business in the United States (such as coal bed methane, 
gas shale, tight gas and oil shales), which, according to data from the Energy Information Administration ("EIA"), is the single 
largest and fastest growing segment of U.S. hydrocarbon production.  We manufacture, fabricate and rent natural gas compressors 
that enhance the production of natural gas wells and provide maintenance services for those compressors.  In addition, we sell 
custom fabricated natural gas compressors to meet customer specifications dictated by well pressures, production characteristics 
and particular applications.  We also manufacture and sell flare systems for oil and gas plant and production facilities.

The vast majority of our rental operations are in non-conventional natural gas and oil regions, which typically have 
lower  initial  reservoir  pressures,  lower  productions  pressures  and/or  faster  well  decline  rates.  These  areas  usually  require 
compression to be installed sooner and with greater frequency.

 Natural gas compressors are used in a number of applications for the production and enhancement of gas wells and 
in  gas  transportation  lines  and  processing  plants.  Compression  equipment  is  often  required  to  boost  a  well’s  production  to 
economically viable levels and enable gas to continue to flow in the pipeline to its destination.

We increased our revenue to $95.9 million in 2015 from $65.2 million in 2011.  During the same period, income from 
operations  increased  to  $15.1  million  from  $14.9  million.  Our  compressor  rental  fleet  has  grown  to  2,622  compressors  at 
December 31, 2015 from 2,120 compressors at the end of 2011.

 Our revenue decreased to $95.9 million from $97.0 million for the year ended December 31, 2015 compared to the  
year ended December 31, 2014. Net income for the year ended December 31, 2015 decreased to $10.1 million ($0.79 per diluted 
share), as compared to $14.1 million ($1.11 per diluted share) for the year ended December 31, 2014.

At  December 31,  2015,  current  assets  were  $73.2  million,  which  included  $35.5  million  of  cash  and  cash 
equivalents.  Current liabilities were $4.6 million, and our line of credit due in 2017 was $417,000. Our stockholders' equity as 
of December 31, 2015 was $224.0 million.

See "Item 6, Management's Discussion and Analysis of Financial Condition and Results of Operations" for further 

financial information.

We were incorporated in Colorado on December 17, 1998  and  maintain our principal offices at 508 W. Wall St., Suite 

550, Midland, Texas 79701 and our telephone number is (432) 262-2700. 

Overview and Outlook

The market for compression equipment and services is substantially dependent on the condition of the natural gas and 
oil industry.  In particular, the willingness of natural gas and oil companies to make capital expenditures on exploration, drilling 
and production of natural gas and oil in the U.S.  The level of activity and capital expenditures has generally been dependent upon 
the prevailing view of future gas and oil prices, which are influenced by numerous factors, including the level of supply or demand 
for natural gas and oil and the impact on price of natural gas and oil, worldwide economic activity, interest rates and the cost of 
capital, environmental regulation, seasonal fluctuations and weather patterns.  Natural gas and oil prices and the level of production 
activity have historically been characterized by significant volatility.  Increasing oil and natural gas prices from 2005 through 
mid-2008  resulted  in  natural  gas  and  oil  operators  increasing  capital  spending  for  exploration,  development  and  production 
programs.  However, in mid-2008, natural gas and oil prices began to decline. This decline resulted in reduced production and 
capital spending by some natural gas and oil companies, and had an impact on demand for compression equipment. 

1

The reduction in capital expenditures and production in the natural gas and oil industry, combined with problems in 
the global economy, led to a downturn in the demand for our products and services in 2009 and 2010. In 2011, a slow recovery 
began which produced an improvement in the utilization rate on our rental fleet and stability in our sales backlog.  In 2012, we 
saw growth in demand for our products and that growth continued in 2013 and 2014.  Towards the end of 2014 oil prices began 
a steep decline which has resulted in capital budget cuts for many energy companies in 2015. These budget reductions translated 
to fewer well completions and a softening of near-term demand for compression that is expected to continue throughout 2016. 
See “Item 1 -- Business – Our Operating Units” and “Business – Backlog” for more information.

According to the U.S. Energy Information Administration (“EIA”), total consumption of natural gas in the United 
States increased 3.2% for the twelve months ended November 2015 compared to the same period 2014. This follows a 2.8% and 
a 2.1% increase in the periods from 2013 to 2014 and 2012 to 2013, respectively.  EIA expects total natural gas consumption in 
the U.S. to increase slightly in 2016.  While we anticipate long-term increased demand for natural gas, we expect our business to 
experience significant pressure on revenues for 2016 due to the overall uncertainty in the combined oil and gas market.

Long-Term Industry Trends

Natural gas prices historically have been volatile, and this volatility is expected to continue. Oil and natural gas are 
linked commodities with many drilling projects producing both products. The sustained oil price collapse that began towards the 
end of 2014 has made some of those drilling projects uneconomic.  Uncertainty continues to exist as to the direction of future 
natural gas and  near-term crude oil price and oil trends are down in the United States and worldwide.  Over the last several years 
gas prices have not shown the resiliency that crude oil prices have and now crude prices are also down sharply.  We believe that 
natural gas is a more environmentally friendly source of energy which is likely to result in increases in demand over time.  Being 
primarily a provider of services and equipment to natural gas producers, we are impacted by changes in natural gas, crude oil and 
condensate prices.  Longer term natural gas prices will be determined by the supply and demand for natural gas as well as the 
prices of competing fuels, such as oil and coal. Prices for oil and natural gas will also be determined by the energy strategies of 
the world's top producing companies.

We believe part of the growth of the rental compression capacity in the U.S. market has been driven by the trend toward 
outsourcing by energy producers and processors.  Renting does not require the purchaser to make large capital expenditures for 
new equipment or to obtain financing through a lending institution.  This allows the customer’s capital to be used for additional 
exploration and production of natural gas and oil. Balance sheet pressure associated with low energy prices could make renting 
an even more likely option, although overall producing activity could slow down.

Notwithstanding the downturn in natural gas prices, we believe that there will continue to be a growing demand for 
natural gas, in the long-term.  We expect long-term demand for our products and services will increase as prices recover as a result 
of:

• 

• 

• 

• 

• 

• 

• 

• 

• 

the increasing demand for energy, both domestically and abroad;

continued non-conventional gas exploration and production;

environmental considerations which provide strong incentives to use natural gas in place of other carbon fuels;

the cost savings of using natural gas rather than electricity for heat generation;

implementation of international environmental and conservation laws;

the aging of producing natural gas reserves worldwide; 

the extensive supply of undeveloped non-conventional natural gas reserves;

the increased drilling for shale oil and its associated gas production; and

the use of our equipment for gas lift on oil wells.

Our Operating Units

We identify our operating units based upon major revenue sources as Gas Compressor Rental, Engineered Equipment 

Sales, Service and Maintenance and Corporate.  

Gas  Compressor  Rental.  Our  rental  business  is  primarily  focused  on  non-conventional  natural  gas  and  oil 
production.  We provide rental of small to medium horsepower compression equipment to customers under contracts typically 

2

 
having minimum initial terms of six to twenty four months.  Historically, in our experience, most customers retain the equipment 
beyond the expiration of the initial term.  By outsourcing their compression needs, we believe our customers are able to increase 
their revenues by producing a higher volume of natural gas due to greater equipment run-time.  Outsourcing also allows our 
customers to reduce their compressor downtime, operating and maintenance costs and capital investments and more efficiently 
meet their changing compression needs. We maintain and service compressor equipment rented to our customers.  

The size, type and geographic diversity of our rental fleet enables us to provide our customers with a range of compression 
units that can serve a wide variety of applications, and to select the correct equipment for the job, rather than the customer trying 
to fit the job to its own equipment.  We base our gas compressor rental rates on several factors, including the cost and size of the 
equipment, the type and complexity of service desired by the customer, the length of contract and the inclusion of any other services 
desired, such as installation, transportation and daily operation.

As of December 31, 2015, we had 2,622 natural gas compressors in our rental fleet totaling 372,482 horsepower, as 
compared to 2,879 natural gas compressors totaling 401,361 horsepower at December 31, 2014.  As of December 31, 2015, we 
had 1,818 natural gas compressors totaling  256,204 horsepower rented to 84 customers, compared to 2,189 natural gas compressors 
totaling 301,392 horsepower rented to 102 customers at December 31, 2014.  As of December 31, 2015, the utilization rate of our 
rental fleet was 69.3% compared to 76.0% as of December 31, 2014.

Engineered Equipment Sales.  This operating unit includes the following components:

•  Compressor fabrication.  Fabrication involves the assembly of compressor components manufactured by us or other 
vendors into compressor units that are ready for rental or sale.  In addition to fabricating compressors for our rental fleet, 
we engineer and fabricate natural gas compressors for sale to customers to meet their specifications based on well pressure, 
production characteristics and the particular applications for which compression is sought.

•  Compressor manufacturing.  We design and manufacture our own proprietary line of reciprocating compressor frames, 
cylinders and parts known as our “CiP”, or Cylinder-in-Plane, product line.  We use the finished components to fabricate 
compressor units for our rental fleet or for sale to customers.  We also sell finished components to other fabricators.

•  Flare fabrication.  We design, fabricate, sell, install and service flare stacks and related ignition and control devices for 
the onshore and offshore incineration of gas compounds such as hydrogen sulfide, carbon dioxide, natural gas and liquefied 
petroleum gases.  Applications for this equipment are often environmentally and regulatory driven, and we believe we 
are a leading supplier to this market.

•  Parts sales and compressor rebuilds.  To provide customer support for our compressor and flare sales businesses, we 
stock varying levels of replacement parts at our Midland, Texas facility and at field service locations.  We also provide 
an exchange and rebuild program for screw compressors and maintain an inventory of new and used compressors to 
facilitate this part of our business.

Service  and  Maintenance.  We  service  and  maintain  compressors  owned  by  our  customers  on  an  “as  needed” 
basis.  Natural  gas  compressors  require  routine  maintenance  and  periodic  refurbishing  to  prolong  their  useful  life.  Routine 
maintenance includes physical and visual inspections and other parametric checks that indicate a change in the condition of the 
compressors.  We perform wear-particle analysis on all packages and perform overhauls on a condition-based interval or a time-
based schedule.  Based on our past experience, these maintenance procedures maximize component life and unit availability and 
minimize downtime.

Business Strategy

During the downturn in the economy beginning in mid 2008, our strategy was to reduce expenses in line with the lower 
anticipated business activity, and fabricate compressor equipment only in direct response to market requirements. As the economy 
recovered, we adjusted this strategy to ensure that we kept pace with growth while balancing appropriate business risk. Entering 
into 2015 we reinstated our proven strategy of reducing expenses and fabricating on an as needed basis and will continue this 
strategy in 2016.  See “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Our 
Performance Trends and Outlook" for more information.  Our long-term intentions to grow our revenue and profitability are based 
on the following business strategies:

•  Expand rental fleet.  We intend to prudently increase the size of our rental fleet by fabricating compressor units in numbers 
that correspond to the growth of the market and in relation to market share gains we may experience.  We believe our 

3

growth will continue to be primarily driven through our placement of small to medium horsepower wellhead natural gas 
compressors for non-conventional natural gas and oil production.

•  Geographic  expansion.  We will continue to consolidate our operations in existing areas, as well as pursue focused 
expansion into new geographic regions as opportunities are identified. We presently provide our products and services 
to a customer base of oil and natural gas exploration and production companies operating in  Colorado, Kansas, Michigan, 
New Mexico, North Dakota, Ohio, Oklahoma, Pennsylvania, Texas, Utah, West Virginia and Wyoming.  

•  Expand our ‘secondary’ product lines.   In addition to our primary rental and engineered product business lines, we will 
emphasize the growth of our other products, e.g., flares, CiP compressor products and general compressor maintenance 
and repair services.

• 

Selectively pursue acquisitions.  We will continue to evaluate potential acquisitions joint ventures and other opportunities 
that would provide us with access to new markets or enhance our current market position.

Competitive Strengths

We believe our competitive strengths include:

• 

Superior customer service.  Our emphasis on the small to medium horsepower markets has enabled us to effectively 
meet the evolving needs of our customers.  We believe these markets have been under-serviced by our larger competitors 
which, coupled with our personalized services and in-depth knowledge of our customers’ operating needs and growth 
plans, have allowed us to enhance our relationships with existing customers as well as attract new customers.  The size, 
type and geographic diversity of our rental fleet enable us to provide customers with a range of compression units that 
can serve a wide variety of applications.  We are able to select the correct equipment for the job, rather than the customer 
trying to fit its application to our equipment.

•  Diversified  product  line.  Our  compressors  are  available  as  high  and  low  pressure  rotary  screw  and  reciprocating 
packages.  They are designed to meet a number of applications, including wellhead production, natural gas gathering, 
natural gas transmission, vapor recovery and gas and plunger lift.  In addition, our compressors can be built to handle a 
variety of gas mixtures, including air, nitrogen, carbon dioxide, hydrogen sulfide and hydrocarbon gases.  A diversified 
compression product line helps us compete by being able to satisfy widely varying pressure, volume and production 
conditions that customers encounter. Our "Flare King" product line provides flares and gas incineration devices to the 
industry for production maintenance and environmental compliance.

•  Purpose-built rental compressors.  Our rental compressor packages have been designed and built to address the primary 
requirements of our customers in the producing regions in which we operate.  Our units are compact in design and are 
easy, quick and inexpensive to move, install and start-up.  Our control systems are technically advanced and allow the 
operator to start and stop our units remotely and/or in accordance with well conditions.  We believe our rental fleet is 
also one of the newest.

•  Experienced management team.  On average, each of our executive and operating team members have over 30 years of 
oilfield services industry experience.  We believe our management team has successfully demonstrated its ability to grow 
our business during times of expansion and to manage through downturns.

•  Broad geographic presence.  We presently provide our products and services to a customer base of oil and natural gas 
exploration and production companies operating in Colorado, Kansas, Michigan, New Mexico, North Dakota, Ohio, 
Oklahoma, Pennsylvania, Texas, Utah, West Virginia and Wyoming.  Our footprint allows us to service many of the 
natural gas producing regions in the United States.  We believe that operating in diverse geographic regions allows us 
better  utilization  of  our  compressors,  minimal  incremental  expenses,  operating  synergies,  volume-based  purchasing, 
leveraged  inventories  and  cross-trained  personnel.  We  also  sell  engineered  compression  products  to  international 
customers.

•  Long-standing  customer  relationships.  We  have  developed  long-standing  relationships  providing  compression 
equipment to many major and independent oil and natural gas companies.  Our customers generally continue to rent our 
compressors after the expiration of the initial terms of our rental agreements, which we believe reflects their satisfaction 
with the reliability and performance of our services and products.

Major Customers

Sales and rental income to Devon Energy Production, Inc. ("Devon") and Occidental Permian, LTD. ("Oxy") for the year 
ended December 31, 2015 amounted to 21% and 10% of our revenue, respectively. Sales and rental income to Devon and EOG 
Resources, Inc. ("EOG") in the year ended December 31, 2014 amounted to 18% and 15% of our revenue, respectively. Sales and 

4

 
 
rental income to EOG and Devon in the year ended December 31, 2013 amounted to 18% and 15% of our revenue. No other single 
customer accounted for more than 10% of our revenues in 2015, 2014 or 2013. 

Oxy  and  Devon  amounted  to  25%  and  10%  of  our  accounts  receivable  as  of  December 31,  2015.  EOG,  Promatcon 
Tepatguna ("Promatcon") and Oxy amounted to 20%, 18% and 14% of our accounts receivable as of December 31, 2014. No other 
customers amounted to more than 10% of our accounts receivable as of December 31, 2015 and 2014. The loss of any of the above 
customers could have a material adverse effect on our business, financial condition, results of operations and cash flows, depending 
upon the demand for our compressors at the time of such loss and our ability to attract new customers.

Sales and Marketing

Our sales force pursues the rental and sales market for compressors and flare equipment and other services in their 
respective territories.  Additionally, our personnel coordinate with each other to develop relationships with customers who operate 
in multiple regions.  Our sales and marketing strategy is focused on communication with current customers and potential customers 
through frequent direct contact, technical assistance, print literature, direct mail and referrals.  Our sales and marketing personnel 
coordinate with our operations personnel in order to promptly respond to and address customer needs.  Our overall sales and 
marketing efforts concentrate on demonstrating our commitment to enhancing the customer’s cash flow through enhanced product 
design, fabrication, manufacturing, installation, customer service and support.

Competition

We  have  a  number  of  competitors  in  the  natural  gas  compression  segment,  some  of  which  have  greater  financial 
resources.  We believe that we compete effectively on the basis of price, customer service, including the ability to place personnel 
in remote locations, flexibility in meeting customer needs, and quality and reliability of our compressors and related services.

Compressor industry participants can achieve significant advantages through increased size and geographic breadth.  As 
the number of rental compressors in our rental fleet increases, the number of sales, support, and maintenance personnel required 
and the minimum level of inventory do not increase proportionately.

Backlog

As  of  December 31,  2015,  we  had  a  sales  backlog  of  approximately  $4.1  million  compared  to  $5.8  million  as  of 
December 31, 2014 .  We expect to fulfill the backlog in the first half of 2016.  Sales backlog consists of firm customer orders for 
which a purchase or work order has been received, satisfactory credit or a financing arrangement exists, and delivery is scheduled.  In 
addition, the major components of our compressors are acquired from suppliers through periodic purchase orders that in many 
instances require three or four months of lead time prior to delivery of the order.

Employees

As of December 31, 2015, we had 263 total employees, none of which are represented by a labor union. We believe 

we have good relations with our employees.

Liability and Other Insurance Coverage

Our equipment and services are provided to customers who are subject to hazards inherent in the oil and natural gas 
industry, such as blowouts, explosions, craterings, fires, and oil spills.  We maintain liability insurance that we believe is customary 
in  the  industry  and  which  includes  environmental  cleanup,  but  excludes  product  warranty  insurance  because  the  majority  of 
components  on  our  compressor  unit  are  covered  by  the  manufacturers.  We  also  maintain  insurance  with  respect  to  our 
facilities.  Based on our historical experience, we believe that our insurance coverage is adequate.  However, there is a risk that 
our insurance may not be sufficient to cover any particular loss or that insurance may not cover all losses.  In addition, insurance 
rates have in the past been subject to wide fluctuation, and changes in coverage could result in less coverage, increases in cost or 
higher deductibles and retentions.

Government Regulation

All of our operations and facilities are subject to numerous federal, state, foreign and local laws, rules and regulations 
related to various aspects of our business, including containment and disposal of hazardous materials, oilfield waste, other waste 
materials and acids.

5

 
 
To date, we have not been required to expend significant resources in order to satisfy applicable environmental laws 
and  regulations.  We  do  not  anticipate  any  material  capital  expenditures  for  environmental  control  facilities  or  extraordinary 
expenditures to comply with environmental rules and regulations in the foreseeable future.  However, compliance costs under 
existing laws or under any new requirements could become material and we could incur liabilities for noncompliance.

Our business is generally affected by political developments and by federal, state, foreign and local laws and regulations, 
which relate to the oil and natural gas industry.  The adoption of laws and regulations affecting the oil and natural gas industry for 
economic, environmental and other policy reasons could increase our costs and could have an adverse effect on our operations.  The 
state and federal environmental laws and regulations that currently apply to our operations could become more stringent in the 
future.

We have utilized operating and disposal practices that were or are currently standard in the industry.  However, materials 
such as solvents, thinner, waste paint, waste oil, wash down waters and sandblast material may have been disposed of or released 
in or under properties currently or formerly owned or operated by us or our predecessors.  In addition, some of these properties 
have been operated by third parties over whom we have no control either as to such entities' treatment of materials or the manner 
in which such materials may have been disposed of or released.

The federal Comprehensive Environmental Response Compensation and Liability Act of 1980, commonly known as 

CERCLA, and comparable state statutes impose strict liability on:

• 

• 

owners and operators of sites, and

persons who disposed of or arranged for the disposal of "hazardous substances" found at sites.

Waste Management and Disposal

The  federal  Resource  Conservation  and  Recovery Act  ("RCRA")  and  analogous  state  laws  and  their  implementing 
regulations govern the generation, transportation, treatment, storage and disposal of hazardous and non-hazardous solid wastes. 
During the course of our operations, we generate wastes (including, but not limited to, used oil, antifreeze, filters, paints, solvents 
and abrasive blasting materials) in quantities regulated under RCRA. The EPA and various state agencies have limited the approved 
methods of disposal for these types of wastes. CERCLA and analogous state laws and their implementing regulations impose 
strict, and under certain conditions, joint and several liability without regard to fault or the legality of the original conduct on 
classes of persons who are considered to be responsible for the release of a hazardous substance into the environment. These 
persons include current and past owners and operators of the facility or disposal site where the release occurred and any company 
that transported, disposed of, or arranged for the transport or disposal of the hazardous substances released at the site. Under 
CERCLA, such persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that 
have been released into the environment, for damages to natural resources and for the costs of certain health studies. In addition, 
where contamination may be present, it is not uncommon for neighboring landowners and other third parties to file claims for 
personal injury, property damage and recovery of response costs allegedly caused by hazardous substances or other pollutants 
released into the environment.

We currently own or lease, and in the past have owned or leased, a number of properties that have been used in support 
of our operations for a number of years. Although we have utilized operating and disposal practices that were standard in the 
industry at the time, hydrocarbons, hazardous substances, or other regulated wastes may have been disposed of or released on or 
under the properties owned or leased by us or on or under other locations where such materials have been taken for disposal by 
companies sub-contracted by us. In addition, some of these properties may have been previously owned or operated by third parties 
whose treatment and disposal or release of hydrocarbons, hazardous substances or other regulated wastes was not under our control. 
These properties and the materials released or disposed thereon may be subject to CERCLA, RCRA and analogous state laws. 
Under such laws, we could be required to remove or remediate historical property contamination, or to perform certain operations 
to prevent future contamination.  We are not currently under any order requiring that we undertake or pay for any cleanup activities.  
However, we cannot provide any assurance that we will not receive any such order in the future.

The federal Water Pollution Control Act and the Oil Pollution Act of 1990 and implementing regulations govern:

• 

• 

the prevention of discharges, including oil and produced water spills, and

liability for drainage into waters.

6

 
 
 
Air Emissions

Our operations are also subject to federal, state, and local regulations.  The Clean Air Act and implementing regulations 
and comparable state laws and regulations regulate emissions of air pollutants from various industrial sources and also impose 
various monitoring and reporting requirements, including requirements related to emissions from certain stationary engines, such 
as those on our compressor units. These laws and regulations impose limits on the levels of various substances that may be emitted 
into the atmosphere from our compressor units and require us to meet more stringent air emission standards and install new 
emission control equipment on all of our engines built after July 1, 2008. In addition, the EPA issued regulations in 2012 that 
require the reduction of emissions of volatile organic compounds, air toxics and methane, a greenhouse gas, at certain oil and gas 
operations. We are not currently aware of material impacts to our operations associated with these rules.

We believe that our existing environmental control procedures are adequate and that we are in substantial compliance 
with environmental laws and regulations, and the phasing in of emission controls and other known regulatory requirements should 
not have a material adverse affect on our financial condition or operational results.  However, it is possible that future developments, 
such as new or increasingly strict requirements and environmental laws and enforcement policies there under, could lead to material 
costs of environmental compliance by us.  While we may be able to pass on the additional cost of complying with such laws to 
our customers, there can be no assurance that attempts to do so will be successful.  Some risk of environmental liability and other 
costs are inherent in the nature of our business, however, and there can be no assurance that environmental costs will not rise.

In recent years,  increased concern has been raised  over the protection of the environment. Legislation to regulate 
emissions of greenhouse gases has been introduced in Congress, and there has been a wide-ranging policy debate, both nationally 
and internationally, regarding the impact of these gases and possible means for their regulation. In addition, efforts have been 
made and continue to be made in the international community toward the adoption of international treaties or protocols that would 
address global climate change issues, such as the United Nations Climate Change Conference in Copenhagen in 2009 and Paris 
Accord in 2015. Also the EPA has undertaken new efforts to collect information regarding greenhouse gas emissions and their 
effects. Recently, the EPA declared that certain greenhouse gases represent a danger to human health and proposed to expand its 
regulations relating to those emissions.  To the extent that new laws or other governmental actions restrict the energy industry or 
impose additional environmental protection requirements that result in increased costs to the oil and gas industry, we could be 
adversely affected.  We cannot determine to what extent our future operations and earnings may be affected by new legislation, 
new regulations or changes in existing regulations.

Occupational Safety and Health 

We are subject to the requirements of Occupational Safety and Health Administration ("OSHA") and comparable state 
statutes. These laws and the implementing regulations strictly govern the protection of the health and safety of employees. The 
OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of CERCLA, and similar 
state statutes require that we maintain and/or disclose information about hazardous materials used or produced in our operations. 
We believe that we are in compliance with these applicable requirements and with other comparable laws.

Patents, Trademarks and Other Intellectual Property

We believe that the success of our business depends more on the technical competence, creativity and marketing abilities 
of our employees than on any individual patent, trademark, or copyright.  Nevertheless, as part of our ongoing research, development 
and  manufacturing  activities,  we  may  seek  patents  when  appropriate  on  inventions  concerning  new  products  and  product 
improvements.  We do not own any unexpired patents.  Although we continue to use the patented technology and consider it useful 
in certain applications, we do not consider the expired patent to be material to our business as a whole.

Suppliers and Raw Materials

Fabrication  of  our  rental  compressors  involves  the  purchase  by  us  of  engines,  compressors,  coolers  and  other 
components, and the assembly of these components on skids for delivery to customer locations.  These major components of our 
compressors  are  acquired  through  periodic  purchase  orders  placed  with  third-party  suppliers  on  an  "as  needed"  basis,  which 
typically  requires  a  three  to  four  month  lead  time  with  delivery  dates  scheduled  to  coincide  with  our  estimated  production 
schedules.  Although we do not have formal continuing supply contracts with any major supplier, we believe we have adequate 
alternative sources available.  In the past, we have not experienced any sudden and dramatic increases in the prices of the major 
components for our compressors.  However, the occurrence of such an event could have a material adverse effect on the results 
of our operations and financial condition, particularly if we are unable to increase our rental rates and sale prices proportionate to 
any such component price increases.

Glossary of Industry Terms

"CiP" - A branded, proprietary gas compressor product line designed, manufactured and packaged by the Company.  
The 'Cylinder in Plane' design results in a compact and vibration-free compressor unit that particularly lends itself to unconventional 
wellhead applications, air compression and compressed natural gas requirements.

"coal  bed  methane"  – A  natural  gas  generated  during  coal  formation  and  provided  from  coal  seams  or  adjacent 

sandstones.

"flare" –  A tall stack equipped with burners used as a safety device at wellheads, refining facilities, gas processing 
plants, and chemical plants. Flares are used for the combustion and disposal of combustible gases. The gases are piped to a remote, 
usually elevated, location and burned in an open flame in the open air using a specially designed burner tip, auxiliary fuel, and 
steam or air. Combustible gases are flared most often due to emergency relief, overpressure, process upsets, startups, shutdowns, 
and other operational safety reasons. Natural gas that is uneconomical for sale is also flared. Often natural gas is flared as a result 
of the unavailability of a method for transporting such gas to markets.

"gas lift" –  A production enhancement technique whereby natural gas is injected into an oil well to increase/improve 

the oil production.

"gas shale" – Fine grained rocks where the predominant gas storage mechanism is absorption and gas is stored in 

volumes that are potentially economic.

"oil shale" – Also referred to as tight oil, is petroleum that consists of light crude oil contained in petroleum-bearing 

formations of low-permeability, often shale or tight sandstone.

"reciprocating compressors" – A reciprocating compressor is a type of compressor which compresses vapor by using 

a piston in a cylinder and a back-and-forth motion.

"screw compressors" – A type of compressor used in low-pressure and vapor compression applications where two 
intermesh rotors create pockets of continuously decreasing volume, in which the gas is compressed and its pressure is increased.

"tight gas" – A gas bearing sandstone or carbonate matrix (which may or may not contain natural fractures) which 

exhibits a low-permeability (tight) reservoir.

RISK FACTORS

You  should  carefully  consider  the  following  risks  associated  with  owning  our  common  stock.  Although  the  risks 
described below are the risks that we believe are material, they are not the only risks relating to our industry, our business and our 
common stock.  Additional risks and uncertainties, including those that we have not yet identified or that we currently believe are 
immaterial, may also adversely affect our business, financial condition or results of operations.

Risks Associated With Our Industry

Adverse macroeconomic and business conditions may significantly and negatively affect our results of operations.

Economic  conditions  in  the  United  States  and  abroad  have,  and  will  likely  continue  to,  affect  our  revenue  and 
profitability. The condition of domestic and global financial markets, continued low  natural gas and oil prices, and the potential 
for disruption and illiquidity in the credit markets could have an adverse effect on our operating results and financial condition, 
and if sustained for an extended period, such adverse effects could become significant.  Uncertainty and turmoil in the credit 
markets may negatively impact the ability of our customers to finance purchases of our products and services and could result in 
a decrease in, or cancellation of, orders included in our backlog or adversely affect the collectability of our receivables. If the 
availability of credit to our customers is reduced, they may reduce their drilling and production expenditures, thereby decreasing 
demand for our products and services, which could have a negative impact on our financial condition. A prolonged period of 
depressed prices for gas and oil would likely result in delays or cancellation of projects by our customers, reducing the demand 
for our products and services.

Decreased oil and natural gas prices and oil and gas industry expenditure levels could adversely affect our revenue.

Our revenue is derived primarily from expenditures in the oil and natural gas industry, which, in turn, are based on 
budgets to explore for, develop and produce oil and natural gas.  When these expenditures decline, our revenue will suffer.  The 
industry’s willingness to explore for, develop and produce oil and natural gas depends largely upon the prevailing view of future 
oil and natural gas prices.  Prices for oil and natural gas historically have been, and are likely to continue to be, highly volatile.  Many 
factors affect the supply and demand for oil and natural gas and, therefore, influence oil and natural gas prices, including:

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the level of oil and natural gas production;

the level of oil and natural gas inventories;

domestic and worldwide demand for oil and natural gas;

the expected cost of developing new reserves;

the cost of producing oil and natural gas;

the level of drilling and completions activity;

inclement weather;

domestic and worldwide economic activity;

regulatory and other federal and state requirements in the United States;

the ability of the Organization of Petroleum Exporting Countries and other large producers to set and maintain production 
levels and prices for oil;

political conditions in or affecting oil and natural gas producing countries;

terrorist activities in the United States and elsewhere;

the cost of developing alternate energy sources;

environmental regulation; and

tax policies.

9

Depending on the market prices of oil and natural gas, companies exploring for oil and natural gas may cancel or curtail 
their drilling programs, thereby reducing demand for our equipment and services.  Our rental contracts are generally short-term, 
and oil and natural gas companies tend to respond quickly to upward or downward changes in prices.  Any reduction in drilling 
and production activities may materially erode both pricing and utilization rates for our equipment and services and adversely 
affects our financial results.  As a result, we may suffer losses, be unable to make necessary capital expenditures and be unable to 
meet our financial obligations.

The intense competition in our industry could result in reduced profitability and loss of market share for us.

We compete with the oil and natural gas industry’s largest equipment and service providers who have greater name 
recognition than we do.  These companies also have substantially greater financial resources, larger operations and greater budgets 
for marketing, research and development than we do.  They may be better able to compete because of their broader geographic 
dispersion and ability to take advantage of international opportunities, the greater number of compressors in their fleet or their 
product and service diversity.  As a result, we could lose customers and market share to those competitors.  These companies may 
also be better positioned than us to successfully endure downturns in the oil and natural gas industry.

Our operations may be adversely affected if our current competitors or new market entrants introduce new products 
or  services  with  better  prices,  features,  performance  or  other  competitive  characteristics  than  our  products  and 
services.  Competitive pressures or other factors also may result in significant price competition that could harm our revenue and 
our business.  Additionally, we may face competition in our efforts to acquire other businesses.

Our industry is highly cyclical, and our results of operations may be volatile.

Our industry is highly cyclical, with periods of high demand and high pricing followed by periods of low demand and 
low pricing.  Periods of low demand intensify the competition in the industry and often result in rental equipment being idle for 
long periods of time.  We may be required to enter into lower rate rental contracts in response to market conditions and our rentals 
and sales revenue may decrease as a result of such conditions. Due to the short-term nature of most of our rental contracts, changes 
in market conditions can quickly affect our business.  As a result of the cyclicality of our industry, our results of operations may 
be volatile in the future.

Increased regulation or ban of current fracturing techniques could reduce demand for our compressors

Fracturing  (frac)  is  a  process  that  results  in  the  creation  of  fractures  in  geological  formations  in  order  to  stimulate 
production from oil and natural gas wells.  Fracturing is also done to increase the rate and ultimate recovery of oil and natural gas. 
Hydraulic frac is the technique that has allowed domestic oil and natural gas exploration and production companies to produce 
massive shale deposits often referred to as unconventional plays. Concerns have been raised over possible environmental damages 
related to fluids used in the frac process.  While the FRAC (Fracturing Responsibility and Awareness of Chemicals) Act has been 
introduced on multiple occasions in Congress, as of February 1, 2016 the Act has yet to be adopted. The FRAC Act seeks to amend 
the Safe Drinking Water Act so that hydraulic fracturing would be regulated on a federal level. In some sates there are initiatives 
at the local level to regulate or ban fracing activities. 

A  ban  of  hydraulic  fracing  would  likely  halt  some  projects,  including  unconventional  projects,  at  least  temporarily. 
Expanded regulations are likely to introduce a period of uncertainty as companies determine ways to proceed.  Any curtailment 
could result in a reduction of demand for our compressors, potentially affecting both sales and rentals of our units.

We are subject to extensive environmental laws and regulations that could require us to take costly compliance actions that 
could harm our financial condition.

Our fabrication and maintenance operations are significantly affected by stringent and complex federal, state and local 
laws  and  regulations  governing  the  discharge  of  substances  into  the  environment  or  otherwise  relating  to  environmental 
protection.  In these operations, we generate and manage hazardous wastes such as solvents, thinner, waste paint, waste oil, wash 
down wastes, and sandblast material.  We attempt to use generally accepted operating and disposal practices and, with respect to 
acquisitions, will attempt to identify and assess whether there is any environmental risk before completing an acquisition.  Based 
on the nature of the industry, however, hydrocarbons or other wastes may have been disposed of or released on or under properties 
owned or leased by us or on or under other locations where such wastes have been taken for disposal.  The waste on these properties 
may be subject to federal or state environmental laws that could require us to remove the wastes or remediate sites where they 
have been released.  We could be exposed to liability for cleanup costs, natural resource and other damages as a result of our 
10

 
 
conduct or the conduct of, or conditions caused by, prior owners, lessees or other third parties.  Environmental laws and regulations 
have changed in the past, and they are likely to change in the future.  If current existing regulatory requirements or enforcement 
policies change, we may be required to make significant unanticipated capital and operating expenditures.

Any  failure  by  us  to  comply  with  applicable  environmental  laws  and  regulations  may  result  in  governmental 

authorities taking actions against our business that could harm our operations and financial condition, including the:

• 

• 

• 

• 

issuance of administrative, civil and criminal penalties;

denial or revocation of permits or other authorizations;

reduction or cessation in operations; and

performance of site investigatory, remedial or other corrective actions.

Risks Associated With Our Company

As of December 31, 2015, a majority of our compressor rentals were for terms of six months or less which, if terminated or not 
renewed, would adversely impact our revenue and our ability to recover our initial equipment costs.

The  length  of  our  compressor  rental  agreements  with  our  customers  varies  based  on  customer  needs,  equipment 
configurations and geographic area.  In most cases, under currently prevailing rental rates, the initial rental periods are not long 
enough to enable us to fully recoup the average cost of acquiring or fabricating the equipment.  We cannot be sure that a substantial 
number of our customers will continue to renew their rental agreements or that we will be able to re-rent the equipment to new 
customers or that any renewals or re-rentals will be at comparable rental rates.  The inability to timely renew or re-rent a substantial 
portion of our compressor rental fleet would have a material adverse effect upon our business, financial condition, results of 
operations and cash flows.

We could be subject to substantial liability claims that could harm our financial condition.

Our products are used in production applications where an accident or a failure of a product can cause personal injury, 
loss of life, damage to property, equipment or the environment, or suspension of operations.  While we maintain insurance coverage, 
we face the following risks under our insurance coverage:

•  we may not be able to continue to obtain insurance on commercially reasonable terms;

•  we may be faced with types of liabilities that will not be covered by our insurance, such as damages from significant 

product liabilities and from environmental contamination;

• 

the dollar amount of any liabilities may exceed our policy limits; and

•  we do not maintain coverage against the risk of interruption of our business.

Any claims made under our policies will likely cause our premiums to increase.  Any future damages caused by our 
products or services that are not covered by insurance, are in excess of policy limits or are subject to substantial deductibles, would 
reduce our earnings and our cash available for operations.

We might be unable to employ qualified technical personnel, which could hamper our present operations or increase our costs.

Many of the compressors that we sell or rent are mechanically complex and often must perform in harsh conditions.  We 
believe that our success depends upon our ability to employ and retain a sufficient number of technical personnel who have the 
ability to design, utilize, enhance and maintain these compressors.  Our ability to expand our operations depends in part on our 
ability to increase our skilled labor force.  The demand for skilled workers is high, and supply is limited.  A significant increase 
in the wages paid by competing employers could result in a reduction of our skilled labor force or cause an increase in the wage 
rates that we must pay or both.  If either of these events were to occur, our cost structure could increase and our operations and 
growth potential could be impaired.

11

We will require a substantial amount of capital to expand our compressor rental fleet and grow our business.

During  2016,  the  amount  we  will  spend  on  capital  expenditures  related  to  rental  compression  equipment  will  be 
determined primarily by the activity of our customers. We do not anticipate demand for our products exceeding what we can fund 
with internally generated funds and bank borrowing with our current credit line.  The amount and timing of any of these capital 
expenditures may vary depending on a variety of factors, including the level of activity in the oil and natural gas exploration and 
production industry and the presence of alternative uses for our capital, including any acquisitions that we may pursue.

Historically, we have funded our capital expenditures through cash flows from operations and borrowings under bank 
credit facilities.  Although we believe that cash flows from our operations will provide us with sufficient cash to fund our planned 
capital expenditures for 2016, we cannot assure you that these sources will be sufficient.  We may require additional capital to 
fund any unanticipated capital expenditures, including any acquisitions, and to fund our growth beyond 2016, and necessary capital 
may not be available to us when we need it or on acceptable terms.  Our ability to raise additional capital will depend on the results 
of our operations and the status of various capital and industry markets at the time we seek such capital.  Failure to generate 
sufficient cash flow, together with the absence of alternative sources of capital, could have a material adverse effect on our business, 
financial condition, results of operations or cash flow.

Of our $30 million line of credit, we owe $417,000 as of December 31, 2015.  All outstanding principal and unpaid 
interest is due on December 31, 2017.  Although we believe that we will be able to renew our existing line of credit, or obtain a 
new line of credit with another lender, we can provide no assurance that we will be successful in renewing our line of credit or 
obtaining a new line.  In addition, any renewal of our existing line of credit or creation of a new line of credit may be on terms 
less favorable that our existing line.  For instance, changes in the terms of a new line of credit may include, but not be limited 
to:  a reduction in the borrowing amount, an increase in interest rate to be paid on borrowings under the line, or restrictive covenants 
that are more onerous than those on our existing line of credit.

We believe that the lender participating in our current credit agreement  has adequate capital and resources. If our 
current  lender were to encounter difficulties, it is possible that the borrowing capacity under our credit agreement would be reduced 
or eliminated. In the event that the availability under our credit agreement was reduced significantly, we could be required to 
obtain capital from alternate sources in order to finance our capital needs. Our options for addressing such capital constraints 
would include, but not be limited to (1) obtaining commitments from other banks to fund increased amounts under the terms of 
our credit agreement, (2) accessing the public capital markets, or (3) delaying certain projects. If it became necessary to access 
additional capital, any alternatives at the time may be on terms less favorable than under our existing credit agreement terms, 
which could have a material effect on our consolidated financial position, results of operations and cash flows.  If future financing 
is not available to us when required, as a result of limited access to the credit markets or otherwise, or is not available to us on 
acceptable terms, we may be unable take advantage of business opportunities or respond to competitive pressures, either of which 
could have a material adverse effect on our consolidated financial position, results of operations and cash flows.

Our debt levels may negatively impact our current and future financial stability.

Should we utilize our full debt capacity, growth beyond that point could be impacted.  As of  December 31, 2015, we 
had an aggregate of approximately $417,000 of outstanding indebtedness, and accounts payable, accrued expenses  and current 
income tax liability of approximately $4.3 million.  As a result of our  indebtedness at any given point in time, we might not have 
the ability to incur any substantial additional indebtedness.  The level of our indebtedness could have several important effects on 
our future operations, including:

• 

• 

• 

our ability to obtain additional financing for working capital, acquisitions, capital expenditures and other purposes may 
be limited;

a significant portion of our cash flow from operations may be dedicated to the payment of principal and interest on our 
debt, thereby reducing funds available for other purposes; and

our leverage if increased to an unacceptable level, could make us more vulnerable to economic downturns.

If we are unable to service our debt, we will likely be forced to take remedial steps that are contrary to our business plan.

As of December 31, 2015, we had $417,000 due under our Line of Credit agreement which allows us to borrow up to 
$30.0 million provided we maintain certain collateral and borrowing base requirements. We believe that our current cash position 
and the amount available under the current revolver are sufficient to meet our capital needs through 2016. However, if we were 
to materially increase our borrowings, it is possible that our business will not generate sufficient cash flow from operations to 

12

 
meet our debt service requirements and the payment of principal when due depending on the amount of borrowings on the agreement 
at any given time.  If this were to occur, we may be forced to:

• 

• 

• 

sell assets at disadvantageous prices;

obtain additional financing; or

refinance all or a portion of our indebtedness on terms that may be less favorable to us.

Our current credit agreement contains covenants that limit our operating and financial flexibility and, if breached, could 
expose us to severe remedial provisions.

Under the terms of our credit agreement, we must:

• 

• 

• 

• 

comply with a minimum leverage ratio;

comply with a commitment coverage ratio;

not exceed specified levels of debt; and

comply with limits on asset sales. 

Our ability to meet the financial ratios and tests under our credit agreement can be affected by events beyond our 
control, and we may not be able to satisfy those ratios and tests.  A breach of any one of these covenants could permit the bank to 
accelerate the debt so that it is immediately due and payable.  If a breach occurred, no further borrowings would be available under 
our credit agreement.  If we were unable to repay the debt, the bank could proceed against and foreclose on our assets, substantially 
all of which have been pledged as collateral to secure payment of our indebtedness.

If we fail to acquire or successfully integrate additional businesses, our growth may be limited and our results of operations 
may suffer.

As part of our business strategy, we intend to evaluate potential acquisitions of other businesses or assets.  However, 
there can be no assurance that we will be successful in consummating any such acquisitions.  Successful acquisition of businesses 
or assets will depend on various factors, including, but not limited to, our ability to obtain financing and the competitive environment 
for acquisitions.  In addition, we may not be able to successfully integrate any businesses or assets that we acquire in the future.  The 
integration of acquired businesses is likely to be complex and time consuming and place a significant strain on management and 
may  disrupt  our  business.  We  also  may  be  adversely  impacted  by  any  unknown  liabilities  of  acquired  businesses,  including 
environmental liabilities.  We may encounter substantial difficulties, costs and delays involved in integrating common accounting, 
information  and  communication  systems,  operating  procedures,  internal  controls  and  human  resources  practices,  including 
incompatibility of business cultures and the loss of key employees and customers.  These difficulties may reduce our ability to 
gain customers or retain existing customers, and may increase operating expenses, resulting in reduced revenues and income and 
a failure to realize the anticipated benefits of acquisitions.

The loss of one or more of our current customers could adversely affect our results of operations.

Our business is dependent not only on securing new customers but also on maintaining current customers. We had two
customers that accounted for an aggregate of approximately 31% of our revenue for the year ended December 31, 2015, and two 
customers  that  accounted  for  an  aggregate  of  approximately  33%  of  our  revenue  for  the  year  ended  December 31,  2014.  At 
December 31, 2015, two customers accounted for an aggregate of 35% of our accounts receivable. Unless we are able to retain 
our existing customers, or secure new customers if we lose one or more of our significant customers, our revenue and results of 
operations would be adversely affected. In addition, the default on payments by one or more of these significant customers may 
negatively impact our cash flow and current assets.

13

Loss of key members of our management could adversely affect our business.

In keeping with our streamlined approach to our business, our executive management team consists of three officers: our 
(i) Chief Executive Officer, (ii) Chief Financial Officer and (iii) Vice President of Technical Services.  We depend on the continued 
employment and performance of these three key members of our executive management team.  In particular, we are significantly 
reliant upon the leadership and guidance of Stephen C. Taylor, who has been our President, Chief Executive Officer and Board 
member since 2004.  In addition to his management duties, Mr. Taylor has been instrumental in our communications and standing 
with the investment community.  If any of our key executives resign or become unable to continue in his present role and is not 
adequately replaced, our business operations could be materially adversely affected.  We do not carry any key-man insurance on 
any of our officers or directors.

Failure to effectively manage our growth and expansion could adversely affect our business and operating results and our 
internal controls.

We have significantly expanded our operations since our formation in 1998 and anticipate that our growth will continue 
if we are able to execute our strategy, subject to the supply and demand for oil and natural gas.  Future growth may place significant 
strain on our management and other resources. To manage our future growth, we must be able to, among other things:

• 

• 

• 

• 

• 

accurately assess the number of additional officers and employees we will require and the areas in which they will be 
required;

attract, hire and retain additional highly skilled and motivated officers and employees;

train and manage our work force in a timely and effective manner;

upgrade and expand our office infrastructure so that it is appropriate for our level of activity; and

improve our financial and management controls, reporting systems and procedures.

Liability to customers under warranties and indemnification provisions may materially and adversely affect our earnings.

We  provide  warranties  as  to  the  proper  operation  and  conformance  to  specifications  of  the  equipment  we 
manufacture.  Our equipment is complex and often deployed in harsh environments.  Failure of this equipment to operate properly 
or to meet specifications may increase our costs by requiring additional engineering resources and services, replacement of parts 
and equipment or monetary reimbursement to a customer.  We have in the past received warranty claims and we expect to continue 
to receive them in the future.  To the extent that we incur substantial warranty claims in any period, our reputation, our ability to 
obtain future business and our earnings could be materially and adversely affected.

Our rental and sales contracts provide for varying forms of indemnification from our customers and in most cases may 
require us to indemnify our customers. Under some of our rental and sales contracts, liability with respect to personnel and property 
is customarily assigned on a “knock-for-knock” basis, which means that we and our customers assume liability for our respective 
personnel and property.  However, in certain rental and sales contracts we assume liability for damage to our customer’s property 
and other third-party on the site resulting from our negligence.  Since our products are used in production applications in the energy 
industry, expenses and liabilities in connection with accidents involving our products and services could be extensive and may 
exceed our insurance coverages.

Failure to maintain effective internal controls could have a material adverse effect on our operations.

Section 404 of the Sarbanes-Oxley Act requires annual management assessments of the effectiveness of our internal 
control over financial reporting.  If we fail to maintain effective internal controls, we may not be able to ensure that we can conclude 
on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-
Oxley Act.  Moreover, effective internal controls are necessary for us to produce reliable financial reports and to help prevent 
financial fraud.  If, as a result of deficiencies in our internal controls, we cannot provide reliable financial reports or prevent fraud, 
our business decision process may be adversely affected, our business and operating results could be harmed, investors could lose 
confidence in our reported financial information, and the price of our stock could decrease as a result.

14

 
A reduction in demand primarily for natural gas or prices for this commodity and credit markets could adversely affect our 
business.

Our results of operations depend upon the level of activity in the energy market, including natural gas development, 
production, processing and transportation. Oil and natural gas prices and the level of drilling and exploration activity can be 
volatile. For example, oil and natural gas exploration and development activity and the number of well completions typically 
decline when there is a significant reduction in oil and natural gas prices or significant instability in energy markets. As a result, 
the demand for our natural gas compression services could be adversely affected. A reduction in demand could also force us to 
reduce our pricing substantially. Additionally, our customers’ production from unconventional natural gas sources such as tight 
sands, shale and coal beds constitute the majority percentage of our business.  Such unconventional sources are generally less 
economically feasible to produce in lower natural gas price environments. These factors could in turn negatively impact the demand 
for our products and services. A decline in demand for oil and natural gas or prices for those commodities and credit markets 
generally have a material adverse effect on our business, financial condition and  results of operations.

The erosion of the financial condition of our customers could adversely affect our business.

Many of our customers finance their exploration and development activities through cash flow from operations, the 
incurrence of debt or the issuance of equity. During times when the oil or natural gas markets weaken, our customers are more 
likely to experience a downturn in their financial condition. Many of our customers’ equity values substantially declined during 
the most recent fall in oil and natural gas prices, and in some cases access to capital markets may be an unreliable source of 
financing for some customers. The combination of a reduction in cash flow resulting from declines in commodity prices, a reduction 
in borrowing bases under reserve-based credit facilities and the lack of availability of debt or equity financing may result in flat 
or moderate growth in our customers’ spending for our products and services in 2016. For example, our customers could seek to 
preserve capital by canceling month-to-month contracts, canceling or delaying scheduled maintenance of their existing natural 
gas compression equipment or determining not to enter into any new natural gas compression service contracts or purchase new 
compression equipment.

Risks Associated With Our Common Stock

The price of our common stock may fluctuate.

The  trading  price  of  our  common  stock  and  the  price  at  which  we  may  sell  securities  in  the  future  are  subject  to 
substantial fluctuations in response to various factors, including our ability to successfully accomplish our business strategy, the 
trading volume of our stock, changes in governmental regulations, actual or anticipated variations in our quarterly or annual 
financial results, our involvement in litigation, general market conditions, the prices of oil and natural gas, announcements by us 
and our competitors, our liquidity, our ability to raise additional funds, and other events.

Future sales of our common stock could adversely affect our stock price.

 Substantial sales of our common stock in the public market, or the perception by the market that those sales could 
occur, may lower our stock price or make it difficult for us to raise additional equity capital in the future. An aggregate of 22% of 
the outstanding shares of our common stock are owned by three institutional investors, each of which owns more than 5% of our 
outstanding shares as of March 2, 2016.  Potential sales of large amounts of these shares in a short period of time by one or more 
of these significant investors could have a negative impact on our stock price.  In addition, potential sales of our common stock 
by our directors and officers, who beneficially own approximately 7% of the outstanding shares of our common stock as of March 2, 
2016, and because of the negative perception of sales by insiders, could also have a negative impact on our stock price.

15

 
 
     
We have a comparatively low number of shares of common stock outstanding and, therefore, our common stock may suffer 
from limited liquidity and its prices will likely be volatile and its value may be adversely affected.

Because of our relatively low number of outstanding shares of common stock, the trading price of our common stock 
will  likely  be  subject  to  significant  price  fluctuations  and  limited  liquidity.  This  may  adversely  affect  the  value  of  your 
investment.  In addition, our common stock price could be subject to fluctuations in response to variations in quarterly operating 
results, changes in management, future announcements concerning us, general trends in the industry and other events or factors 
as well as those described above.

If we issue debt or equity securities, you may lose certain rights and be diluted.

If we raise funds in the future through the issuance of debt or equity securities, the securities issued may have rights 
and preferences and privileges senior to those of holders of our common stock, and the terms of the securities may impose restrictions 
on our operations or dilute your ownership in our Company.

If securities analysts downgrade our stock or cease coverage of us, the price of our stock could decline.

The trading market for our common stock relies in part on the research and reports that industry or financial analysts 
publish about us or our business.  We do not control these analysts.  Furthermore, there are many large, well-established, publicly 
traded companies active in our industry and market, which may mean that it is less likely that we will receive widespread analyst 
coverage.  If one or more of the analysts who do cover us downgrade our stock, our stock price would likely decline rapidly.  If 
one or more of these analysts cease coverage of our company, we could lose visibility in the market, which in turn could cause 
our stock price to decline.

We do not intend to pay, and have restrictions upon our ability to pay, dividends on our common stock.

We have not paid cash dividends in the past and do not intend to pay dividends on our common stock in the foreseeable 
future.  Net income from our operations, if any, will be used for the development of our business, including capital expenditures, 
and to retire debt.  In addition, our credit agreement contains restrictions on our ability to pay cash dividends on our common 
stock.

Provisions contained in our governing documents could hinder a change in control of us.

Our articles of incorporation and bylaws contain provisions that may discourage acquisition bids and may limit the 

price investors are willing to pay for our common stock.  Our articles of incorporation and bylaws provide that:

• 

• 

• 

• 

directors are elected for three-year terms, with approximately one-third of the board of directors standing for election 
each year;

cumulative voting is not allowed, which limits the ability of minority shareholders to elect any directors;

the unanimous vote of the board of directors or the affirmative vote of the holders of not less than 80% of the votes 
entitled to be cast by the holders of all shares entitled to vote in the election of directors is required to change the size of 
the board of directors; and

directors may be removed only for cause and only by the holders of not less than 80% of the votes entitled to be cast on 
the matter.

Our Board of Directors has the authority to issue up to five million shares of preferred stock.  The Board of Directors 
can fix the terms of the preferred stock without any action on the part of our stockholders.  The issuance of shares of preferred 
stock may delay or prevent a change in control transaction.  In addition, preferred stock could be used in connection with the 
Board of Directors’ adoption of a shareholders’ rights plan (also known as a poison pill), which would make it much more difficult 
to effect a change in control of our company through acquiring or controlling blocks of stock.  Also, our directors and officers as 
a group will continue to beneficially own stock and although this is not a majority of our stock, it confers substantial voting power 
in the election of directors and management of our company.  This would make it difficult for other minority stockholders to effect 
a change in control or otherwise extend any significant control over our management.  This may adversely affect the market price 
and interfere with the voting and other rights of our common stock.

Non-GAAP Financial Measures

Our definition and use of Adjusted EBITDA

“Adjusted EBITDA” is a non-GAAP financial measure that we define as earnings (net income) from operations before 
interest, taxes, loss on retirement of rental equipment, depreciation and amortization.  This term, as used and defined by us, may 
not be comparable to similarly titled measures employed by other companies and is not a measure of performance calculated in 
accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for operating income, net income 
or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared 
in accordance with GAAP.  However, management believes Adjusted EBITDA is useful to an investor in evaluating our operating 
performance because:

• 

• 

• 

it is widely used by investors in the energy industry to measure a company’s operating performance without regard to 
items  excluded  from  the  calculation  of Adjusted  EBITDA,  which  can  vary  substantially  from  company  to  company 
depending upon accounting methods and book value of assets, capital structure and the method by which assets were 
acquired, among other factors;

it helps investors to more meaningfully evaluate and compare the results of our operations from period to period by 
removing the impact of our capital structure and asset base from our operating structure; and

it is used by our management for various purposes, including as a measure of operating performance, in presentations to 
our  Board  of  Directors,  as  a  basis  for  strategic  planning  and  forecasting,  and  as  a  component  for  setting  incentive 
compensation.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute 

for analysis of our results as reported under generally accepted accounting principles.  Some of these limitations are:

•  Adjusted EBITDA does not reflect our cash expenditures, or future requirements for capital expenditures or 

contractual commitments;

•  Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•  Adjusted EBITDA does not reflect the cash requirements necessary to service interest or principal payments on our 

debts; and

• 

although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often 
have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.

There are other material limitations to using Adjusted EBITDA as a measure of performance, including the inability 
to analyze the impact of certain recurring items that materially affect our net income or loss, and the lack of comparability of 
results of operations of different companies.  Please read the table below under “Reconciliation” to see how Adjusted EBITDA 
reconciles to our net income, the most directly comparable GAAP financial measure.

Definition and use of gross margin

We define gross margin as total revenue less costs of revenues (excluding depreciation and amortization expense).  Gross 
margin is included as a supplemental disclosure because it is a primary measure used by our management as it represents the 
results of revenue and costs (excluding depreciation and amortization expense), which are key components of our operations.  Gross 
margin differs from gross profit, in that gross profit includes depreciation expense.  We believe gross margin is important because 
it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets 
acquired or constructed that are utilized in those operations, the indirect costs associated with our selling, general and administrative 
activities, the impact of our financing methods and income taxes.  Depreciation expense does not accurately reflect the costs 
required to maintain and replenish the operational usage of our assets and therefore may not portray the costs from current operating 
activity.  Rather,  depreciation  expense  reflects  the  systematic  allocation  of  historical  property  and  equipment  values  over  the 
estimated useful lives.

Gross margin has certain material limitations associated with its use as compared to net income.  These limitations are 
primarily due to the exclusion of certain expenses.  Each of these excluded expenses is material to our results of operations.  Because 
we use capital assets, depreciation expense is a necessary element of our costs and our ability to generate revenue and selling, 
general and administrative expense is a necessary cost to support our operations and required corporate activities.  In order to 
compensate for these limitations, management uses this non-GAAP measure as a supplemental measure to other GAAP results to 
provide a more complete understanding of our performance.

21

As  an  indicator  of  our  operating  performance,  gross  margin  should  not  be  considered  an  alternative  to,  or  more 
meaningful than, net income as determined in accordance with GAAP.  Our gross margin may not be comparable to a similarly 
titled measure of another company because other entities may not calculate gross margin in the same manner.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 
OF OPERATIONS

The following discussion is intended to assist you in understanding our financial position and results of operations for 
each of the years ended December 31, 2015, 2014 and 2013.  You should read the following discussion and analysis in conjunction 
with our audited financial statements and the related notes.

The following discussion contains forward-looking statements.  For a description of limitations inherent in forward-

looking statements, see “Special Note Regarding Forward-Looking Statements” on page ii.

Overview

We fabricate, manufacture, rent and sell natural gas compressors and related equipment.  Our primary focus is on the 
rental of natural gas compressors.  Our rental contracts generally provide for initial terms of six to 24 months.  After the initial 
term of our rental contracts, most of our customers have continued to rent our compressors on a month-to-month basis.  Rental 
amounts include maintenance charges and are paid monthly in advance.  As of December 31, 2015, we had  1,818 natural gas 
compressors totaling  256,204 horsepower rented to 84 customers, compared to 2,189 natural gas compressors totaling 301,392
horsepower rented to 102 customers at December 31, 2014.  Of the 1,818 compressors rented at December 31, 2015, 833 were 
rented on a month-to-month basis.

We also fabricate natural gas compressors for sale to our customers, designing compressors to meet unique specifications 
dictated by well pressures, production characteristics and particular applications for which compression is sought.  Fabrication of 
compressors involves the purchase by us of engines, compressors, coolers and other components, and then assembling these 
components on skids for delivery to customer locations.  These major components of our compressors are acquired through periodic 
purchase orders placed with third-party suppliers on an “as needed” basis, which presently requires a three to four month lead 
time with delivery dates scheduled to coincide with our estimated production schedules.  Although we do not have formal continuing 
supply contracts with any major supplier, we believe we have adequate alternative sources available.  In the past, we have not 
experienced any sudden and dramatic increases in the prices of the major components for our compressors.  However, the occurrence 
of such an event could have a material adverse effect on the results of our operations and financial condition, particularly if we 
were unable to increase our rental rates and sales prices proportionate to any such component price increases.

22

 
 
 
We also manufacture a proprietary line of compressor frames, cylinders and parts, known as our CiP (Cylinder-in-
Plane) product line.  We use finished CiP component products in the fabrication of compressor units for sale or rental by us or sell 
the finished component products to other compressor fabricators.  We also design, fabricate, sell, install and service flare stacks 
and related ignition and control devices for onshore and offshore incineration of gas compounds such as hydrogen sulfide, carbon 
dioxide, natural gas and liquefied petroleum gases.  To provide customer support for our compressor and flare sales businesses, 
we stock varying levels of replacement parts at our Midland, Texas facility and at field service locations.  We also provide an 
exchange and rebuild program for screw compressors and maintain an inventory of new and used compressors to facilitate this 
business.

We provide service and maintenance to our non-rental customers under written maintenance contracts or on an as 
required basis in the absence of a service contract.  Maintenance agreements typically have terms of six months to one year and 
require payment of a monthly fee.

The following table sets forth our revenues from each of our three operating categories for the periods presented:

Our  strategy  for  growth  is  focused  on  our  compressor  rental  business.  Margins,  exclusive  of  depreciation  and 
amortization, for our rental business historically run in the high 50% to low 60% range, while margins for the compressor sales 
business tend to be in the mid 20% range.  If our rental business grows and contributes a larger percentage of our total revenues, 
we expect our overall company-wide margins to improve over time.

The oil and natural gas equipment rental and services industry is cyclical in nature.  The most critical factor in assessing 
the outlook for the industry is the worldwide supply and demand for natural gas and oil and the corresponding changes in commodity 
prices.  As demand and prices increase, oil and natural gas producers increase their capital expenditures for drilling, development 
and production activities.  Generally, the increased capital expenditures ultimately result in greater revenues and profits for service 
and equipment companies.

In general, we expect our overall business activity and revenues to track the level of activity in the natural gas industry, 
with changes in domestic natural gas production and consumption levels and prices more significantly affecting our business than 
changes in crude oil and condensate production and consumption levels and prices.  We also believe that demand for compression 
services and products is driven by declining reservoir pressure in maturing natural gas producing fields and, more recently, by 
increased focus by producers on non-conventional natural gas production, such as coal bed methane, gas shale and tight gas, which 
typically requires more compression than production from conventional natural gas reservoirs.

Demand for our products and services was strong throughout most of 2008, but in 2009 the demand declined due to 
lower natural gas prices, decreased demand for natural gas and the economic recession.  During 2010, the economy began to 
recover from a global recession and demand for our products began to strengthen. This recovery continued through most of 2014 
due to increasing oil prices, in spite of continued low natural gas prices. Towards the end of 2014 and throughout 2015, crude oil 
prices collapsed, placing uncertainty on the growth in demand for our products and services. 

For fiscal year 2016, our forecasted capital expenditures will be directly dependent upon our customers’ compression 
requirements and are not anticipated to exceed our internally generated cash flows.  Any required capital will be for additions to 
our compressor rental fleet and/or addition or replacement of service vehicles.  We believe that cash flows from operations will 
be  sufficient  to  satisfy  our  capital  and  liquidity  requirements  through  2016.  We  may  require  additional  capital  to  fund  any 
unanticipated expenditures, including any acquisitions of other businesses, joint ventures or other opportunities, although that 
capital may not be available to us when we need it or on acceptable terms.

Notwithstanding the continued uncertain economy and low energy price environment, we believe the long-term trend 

in our market is favorable.

Critical Accounting Policies and Practices

We have identified the policies below as critical to our business operations and the understanding of our results of 
operations.  In the ordinary course of business, we have made a number of estimates and assumptions relating to the reporting of 
results of operations and financial condition in the preparation of our financial statements in conformity with accounting principles 
generally accepted in the United States.  Actual results could differ significantly from those estimates under different assumptions 
and conditions.  We believe that the following discussion addresses our most critical accounting policies, which are those that are 
most important to the portrayal of our financial condition and results of operations and require our most difficult, subjective, and 
complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

Our critical accounting policies are as follows:

revenue recognition;

estimating the allowance for doubtful accounts receivable;

accounting for income taxes;

valuation of long-lived and intangible assets and goodwill; and

valuation of inventory.

Revenue Recognition

Revenue from the sales of custom and fabricated compressors and flare systems is recognized when title passes to the 
customer, the customer assumes risks and rewards of ownership, collectability is reasonably assured and delivery occurs as directed 
by our customer.  However, in certain circumstances customers request a bill and hold arrangement, in which case sales revenue 
is recognized before delivery occurs. Under these bill and hold arrangements, the compressor or flare is available for shipment, 
the Company has fulfilled all of its pre-delivery performance obligations and the customer has completed and signed a bill and 
hold agreement. Revenue from sale of rental units is included in sales revenue when equipment is shipped or title is transferred 
to the customer.  Exchange and rebuild compressor revenue is recognized when both the replacement compressor has been delivered 
and the rebuild assessment has been completed.  Revenue from compressor services is recognized upon providing services to the 
customer.  Maintenance agreement revenue is recognized as services are rendered.  Rental revenue is recognized over the terms 
of the respective rental agreements.  Deferred income represents payments received before a product is shipped.

Allowance for Doubtful Accounts Receivable

We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history and the 
customer’s current credit worthiness, as determined by our review of their current credit information.  We continuously monitor 
collections  and  payments  from  our  customers  and  maintain  a  provision  for  estimated  credit  losses  based  upon  our  historical 
experience and any specific customer collection issues that we have identified.  While such credit losses have historically been 
within our expectations and the provisions established, we cannot guarantee that we will continue to experience the same credit 
loss rates that we have in the past.  At December 31, 2015, two customers accounted for approximately 25% and 10% of our 
accounts receivable, and at December 31, 2014, three customers accounted for approximately 20%, 18% and 14%  of our accounts 
receivable.  A significant change in the liquidity or financial position of these customers could have a material adverse impact on 
the collectability of our accounts receivables and our future operating results.  At December 31, 2015 and 2014, our allowance 
for doubtful accounts balance was $833,000 and $507,000, respectively.

Accounting for Income Taxes

As part of the process of preparing our financial statements, we are required to estimate our federal income taxes as 
well as income taxes in each of the states in which we operate.  This process involves us estimating our actual current tax exposure 
together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes.  These 
differences result in deferred tax assets and liabilities, which are included in our balance sheet.  We must then assess the likelihood 
that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not probable, 
we must establish a valuation allowance.  To the extent we establish a valuation allowance or increase this allowance in a period, 
we must include an expense in the tax provision in the statement of operations.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets 
and liabilities and any valuation allowance recorded against our net deferred tax assets.  We currently have no valuation allowance 
and fully expect to utilize all of our deferred tax assets.

24

Valuation of Long-Lived and Intangible Assets and Goodwill

We assess the impairment of identifiable intangibles, long-lived assets and related goodwill annually or whenever 
events or changes in circumstances indicate that the carrying value may not be recoverable.  Factors we consider important which 
could trigger an impairment review include the following:

• 

• 

• 

• 

significant underperformance relative to expected historical or projected future operating results;

significant changes in the manner of our use of the acquired assets or the strategy for our overall business;

significant negative industry or economic trends; and

significant decline in the market value of our stock.

When we determine that the carrying value of intangibles, long-lived assets and related goodwill may not be recoverable 
based upon the existence of one or more of the above indicators of impairment, we measure any impairment based on a projected 
discounted cash flow method using a discount rate determined by our management to be commensurate with the risk inherent in 
our current business model.

We completed a review of goodwill for impairment during the fourth quarter of 2015 under the guidance of Accounting 
Standards Update 2012-02, Intangibles--Goodwill and Other (Topic 350): Testing Indefinite-lived Intangibles for Impairment 
(ASU 2012-02). Our analysis considered multiple qualitative factors to determine whether events and circumstances indicate that 
we more than likely than not experienced impairment to the stated value of goodwill.  Our assessment included a review of changes 
in key company financial metrics, stock performance and other measures that are important to the company's success.  The other 
measure included demand for our products and services, maintenance of customers and cost of producing our product.  Based on 
the analysis we concluded that it is more likely than not that we have not incurred impairment and are not required to take further 
action.  As a result, no impairment of goodwill was recorded in the year ending at December 31, 2015.  Future impairment tests 
could result in impairments of our intangible assets or goodwill.

Inventories

We value our inventory at the lower of the actual cost to purchase and/or manufacture the inventory or the current 
estimated market value of the inventory.  We regularly review inventory quantities on hand and record a provision for excess and 
obsolete inventory based primarily on our estimated forecast of product demand and production requirements.  At December 31, 
2015, an adjustment to the allowance of $418,000 was made to remove obsolete inventory and bring inventory to current estimated
market value, which represents 1.5% of inventory.  This adjustment was the result of our obsolescence review which is conducted 
each year. We ended 2015 with an inventory allowance balance of $12,000.

Our Performance Trends and Outlook

Given the current economic environment in North America and anticipated impact of continued low natural gas and 
oil prices and potentially cautious capital spending by customers, we expect the overall activity levels to be lower in 2016. Currently, 
we believe that weak commodity prices will continue throughout 2016. In addition, credit and capital markets will show signs of 
stress resulting from the  weakness of commodity prices and will impact the level of capital spending by our customers in the near 
term. We believe that the recovery from the recent market uncertainty will continue to be slow. The result will likely be lagging 
capital spending by our customers and therefore slow growth in demand for our products and services and price pressure from 
competitors.  We anticipate industry capital spending will be greatly decreased in 2016 compared to 2015 levels, and we believe 
our fabrication business will likely reflect this in our production level through 2016. We believe our rental operations business 
will also be down moderately.

Total revenue decreased to $95.9 million from $97.0 million, or 1.1%, for the year ended December 31, 2015, compared 
to 2014. This was the result of a  3.2% decrease in rental revenue offset by a  7.7% increase in sales revenue and a 22.4% increase 
in service and maintenance revenue. 

Rental revenue decreased to $76.4 million from $79.0 million, or 3.2%, for the year ended December 31, 2015, compared 
to 2014.  This decrease is due to reduced demand from the drop in oil and natural prices resulting in units being returned. As of 
December 31, 2015, we had 2,622 natural gas compressors in our rental fleet totaling 372,482 horsepower, as compared to 2,879
natural gas compressors totaling  401,361 horsepower as of December 31, 2014.  As of December 31, 2015, we had 1,818 natural 
gas compressors totaling  256,204 horsepower rented to 84 customers, compared to 2,189 natural gas compressors totaling 301,392
horsepower rented to 102 customers as of December 31, 2014. The rental fleet had a utilization of 69.3% as of December 31, 2015
as compared to 76.0% at year end 2014.

Sales revenue increased to $18.5 million from $17.2 million, or 7.7%, for the year ended December 31, 2015, compared 
to 2014. Our normal sales activity continues to reflect demand from our customers' continued investment in non-conventional 
shale plays which require compression for produced natural gas. The price of natural gas on December 31, 2015 was $2.28/MMBtu, 
down from $3.14/MMBtu one year ago. The price of natural gas remains at levels that are considered depressed.  Because of 
lagging natural gas prices, along with economic uncertainty and continued tight credit markets, the energy industry continues to 
encounter reduced capital spending, particularly for goods and services with respect to natural gas activities. During 2015, capital 
project funding continued to shift from gas projects to oil projects as the price of oil in early 2015 was not as volatile as gas, and 
many companies had locked in oil prices in support of those projects. Since our compressors are increasingly used in the production 
of oil and natural gas from shale plays which are driven by oil economics and typically by hedged prices, we have been able to 
increase our sales. Our strategy over time has been to increase our rental revenues so that they are a larger component of total 
revenue, but we intend to maintain our ability to build and sell custom fabricated equipment. In support of this, we have and will 
continue to cultivate new sales oriented customers and are actively pursuing small, medium and large reciprocating compressors 
as well as rotary screw-type equipment of any size. Sales include: (1) compressor unit sales, (2) flare sales, (3) parts sales and (4) 
compressor rebuilds.

The overall gross margin percentage remained steady at 55.5% for the twelve months ended December 31, 2015 and 
December 31, 2014, exclusive of depreciation and amortization. Our ability to remain flat in today's market is the result of  the 
relatively higher margin rentals comprising a larger share of total revenue. Rental margins increased for the year ended December 31, 
2015 compared to 2014 to 62.4% from 60.1%. Sales margin decreased to 26.4% from 34.3% for the year ended 2015 compared 
to 2014. Third party service and maintenance margins increased to 71.9% from 58.5% for the year ended December 31, 2015
compared to 2014. Service and maintenance represents 1% of our revenue providing minimal impact on our overall gross margin.

26

 
 
 
 
 
As a result of a decline in market conditions, management reviewed our rental compressor units and determined that 258 
units should be retired, with certain key components being re-utilized, representing total horsepower of 32,259. Based on this 
optimization review, at June 30, 2015 we recorded a $4.4 million non-cash loss on the retirement of rental equipment to reduce 
the book value to approximately $967,000, the estimated fair value of the key components being kept.

Selling, general, and administrative expenses increased to $11.0 million for the year ended December 31, 2015, as 
compared to $10.3 million for 2014.  This 6.3% increase is primarily due to  our need to maintain consistent staffing levels, salary 
increases for existing staff ($180,000)  and non-cash expenses related to stock compensation ($300,000).   

Depreciation and amortization expense increased to $22.8 million from $21.5 million, or 5.8%, for the year ended 
December 31, 2015, compared to 2014.  This increase was the net result of 52 new gas compressor rental units being added to the 
rental fleet in 2015, which increased the depreciable base and a full year's of depreciation realized from the 323 rental units added 
in 2014.

Provision for income tax decreased to $5.1 million from $8.0 million, or 36.3%, and is the result of the decrease in 

pre-tax income and effective tax rate.  Our effective tax rate was 33.5% for 2015 and 36.2% for 2014.

Total revenue increased to $97.0 million from $89.2 million, or 8.7%, for the year ended December 31, 2014, compared 
to 2013. This was the result of a 11.7% decrease in sales revenue offset by a 14.4% increase in rental revenue and a 11.9% increase 
in service and maintenance revenue. 

Rental  revenue  increased  to  $79.0  million  from  $69.1  million,  or  14.4%,  for  the  year  ended  December 31,  2014, 
compared to 2013.  This increase was the result of improved rental pricing of our units and our ability to place additional units in 
service. As of December 31, 2014, we had 2,879 natural gas compressors in our rental fleet totaling 401,361 horsepower, as 
compared to 2,556 natural gas compressors totaling  351,187 horsepower at December 31, 2013.  As of December 31, 2014, we 
had 2,189 natural gas compressors totaling  301,392 horsepower rented to 102 customers, compared to 2,038 natural gas compressors 
totaling  283,165  horsepower  rented  to  95  customers  at  December 31,  2013. The  rental  fleet  had  a  utilization  of  76.0%  as  of 
December 31, 2014 as compared to 79.7% at year end 2013.

Sales revenue decreased to $17.2 million from $19.5 million, or 11.7%, for the year ended December 31, 2014, compared 
to 2013. Our normal sales activity continues to reflect demand from our customers' continued investment in non-conventional 
shale plays which require compression for produced natural gas. The price of natural gas on December 31, 2014 was $3.14/MMBtu, 
down from $4.31/MMBtu at December 31, 2013. The price of natural gas remains at levels that are considered depressed.  Because 
of lagging natural gas prices, along with economic uncertainty and continued tight credit markets, the energy industry continues 
to encounter reduced capital spending, particularly for goods and services with respect to natural gas activities. This has caused 
capital project funding to shift from gas projects to oil projects as the price of oil was not as volatile as gas, and oil prices have 
rebounded from its lows compared to natural gas prices. Since our compressors are increasingly used in the production of natural 
gas from shale plays which are driven by oil economics, we have been able to increase our sales. Our strategy over time has been 
27

 
 
 
 
 
 
to increase our rental revenues so that they are a larger component of total revenue, but we intend to maintain our ability to build 
and sell custom fabricated equipment. In support of this, we have continued to cultivate new sales-oriented customers and are 
entertaining requests for bids on larger reciprocating compressors instead of being solely focused on screw-type equipment. Sales 
included: (1) compressor unit sales, (2) flare sales, (3) parts sales and (4) compressor rebuilds.

The overall gross margin percentage increased to 55.5% for the twelve months ended December 31, 2014, from 54.1% 
for the same period ended December 31, 2013, exclusive of depreciation and amortization. This increase is the result of  the 
relatively higher margin rentals comprising a larger share of total revenue. Rental revenue increased by 14.4% while sales revenue 
declined. Rental margins increased for the year ended December 31, 2014 compared to 2013 from 58.0% to 60.1%. Sales margin 
decreased to 34.3% from 40.5% for the year ended 2014 compared to 2013. Third party service and maintenance margins increased 
to 58.5% from 51.3% for the year ended December 31, 2014 compared to 2013. Service and maintenance represents less than 1% 
of our revenue providing minimal impact on our overall gross margin.

Selling, general, and administrative expense increased to $10.3 million for the year ended December 31, 2014, as 
compared to $8.1 million for 2013.  This 26.9% increase is primarily due to  our need to maintain consistent staffing levels, salary 
increases for existing staff ($243,000)  and non-cash expenses related to stock compensation ($1.5 million).   

Depreciation and amortization expense increased to $21.5 million from $18.1 million, or 18.5%, for the year ended 
December 31, 2014, compared to 2013.  This increase was the net result of 323 new gas compressor rental units being added to 
the rental fleet in 2014, thus increasing the depreciable base.

Provision for income tax decreased to $8.0 million from $8.1 million, or 1.1%, and is the result of the decrease in 

taxable income.  Our effective tax rate was 36.2% for 2014 and 36.1% for 2013.

Historically, we have funded our operations through cash flows from operations and borrowings under bank credit 
facilities. Proceeds of financings have been primarily used to repay debt, to fund the manufacture and fabrication of additional 
units for our rental fleet of natural gas compressors and for acquisitions.  In recent years, we have primarily funded our operations 
through cash flow from operations and, to a lesser extent, borrowings under our bank line of credit, which is described below.  For 
the  year  ended  December 31,  2015,  we  invested  approximately  $12.5  million  in  equipment  for  our  rental  fleet  and  service 
vehicles.  We financed this activity with funds from operations.  

28

 
 
 
 
 
Cash flows

At December 31, 2015, we had cash and cash equivalents of $35.5 million and working capital of $68.6 million, and 
total debt of $417,000 under our credit agreement, all which is due in 2017. Our cash and cash equivalents increased from 2014 
due to a decrease in our capital program which was the result of a decrease in compressor rentals due to the decrease in oil and 
natural gas prices.We had positive net cash flow from operating activities of approximately $41.6 million during 2015. This was 
primarily from net income of $10.1 million and non-cash items of depreciation and amortization of $22.8 million, $3.5 million 
related to stock-based compensation, a loss on retirement of rental fleet of $4.4 million, a decrease in deferred income taxes of 
$1.8 million and an increase in working capital of $2.6 million.

At December 31, 2014, we had cash and cash equivalents of $6.2 million, working capital of $41.8 million and total 
debt of $417,000, under our line of credit, all which is due in 2017. Our cash and cash equivalent decreased from 2013 due to an 
increase in demand from our customers for additional rental compression. We had positive net cash flow from operating activities 
of approximately $34.6 million during 2014. This was primarily from net income of $14.1 million plus depreciation and amortization 
of $21.5 million.

    Raw materials and work in progress and finished goods inventory decreased to $27.7 million as of the end of 2015, 
as compared to $32.6 million as of the end of 2014. This decrease is mainly a reflection of inventory management activity and 
the timing of jobs closing from work in progress to finished goods.

Contractual Obligations and Commitments

On November 19, 2014, we amended and renewed our $30 million Credit Agreement with JP Morgan Chase Bank, N.A.  
("the Amended Credit Agreement"). The Amended Credit Agreement was extended to December 31, 2017, and the interest rate 
terms were amended. We also have a right to request from the lender, on an uncommitted basis, an increase of up to $20 million 
on the aggregate commitment (which could potentially increase the commitment amount to $50 million). As of December 31, 
2015, we owed $417,000 on the line of credit under the Credit Agreement.

Borrowing Base. At any time before the maturity of the Amended Credit Agreement, we may draw, repay and re-borrow amounts 
available under the borrowing base up to the maximum aggregate availability discussed above. Generally, the borrowing base 
equals the sum of (a) 80% of our eligible accounts receivable plus (b) 50% of the book value of our eligible general inventory 
(not  to  exceed  50%  of  the  commitment  amount  at  the  time)  plus  (c)  75%  of  the  book  value  of  our  eligible  equipment 
inventory.  JPMorgan Chase Bank (the “Lender”) may adjust the borrowing base components if material deviations in the collateral 
are discovered in future audits of the collateral.

Interest and Fees.  Under the terms of the Amended Credit Agreement, we have the option of selecting the applicable variable 
rate for each revolving loan, or portion thereof, of either (a) LIBOR multiplied by the Statutory Reserve Rate (as defined in the 
Amended Credit Agreement), with respect to this rate, for Eurocurrency funding, plus the Applicable Margin (“LIBOR-based”), 
or (b) CB Floating Rate, which is the Lender’s Prime Rate less the Applicable Margin; provided, however, that no more than three 
LIBOR-based borrowings under the agreement may be outstanding at any one time. For purposes of the LIBOR-based interest 
rate, the Applicable Margin is 1.50%. For purposes of the CB Floating Rate, the Applicable Margin is 1.25%.  Accrued interest is 
payable monthly on outstanding principal amounts, provided that accrued interest on LIBOR-based loans is payable at the end of 

29

       
 
  
 
each interest period, but in no event less frequently than quarterly. In addition, fees and expenses are payable in connection with 
our requests for letters of credit (generally equal to the Applicable Margin for LIBOR-related borrowings multiplied by the face 
amount of the requested letter of credit) and administrative and legal costs.

Maturity. The maturity date of the Amended Credit Agreement is December 31, 2017, at which time all amounts borrowed under 
the agreement will be due and outstanding letters of credit must be cash collateralized. The agreement may be terminated early 
upon our request or the occurrence of an event of default.

Security. The obligations under the Amended Credit Agreement are secured by a first priority lien on all of our inventory and 
accounts and leases receivables, along with a first priority lien on a variable number of our leased compressor equipment the book 
value of must be maintained at a minimum of 2.00 to 1.00 commitment coverage ratio (such ratio being equal to (i) the amount 
of the borrowing base as of such date to (ii) the amount of the commitment as of such date.)

Covenants. The Amended Credit Agreement contains customary representations and warranties, as well as covenants which, among 
other things, limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions 
in excess of certain amounts; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make 
negative pledges; consolidate, merge or effect asset sales; or change the nature of our business.

Events of Default and Acceleration. The Amended Credit Agreement contains customary events of default for credit facilities of 
this size and type, and includes, without limitation, payment defaults; defaults in performance of covenants or other agreements 
contained in the transaction documents; inaccuracies in representations and warranties; certain defaults, termination events or 
similar events;  certain defaults with  respect to  any other  Company indebtedness  in  excess  of  $50,000;  certain bankruptcy or 
insolvency events; the rendering of certain judgments in excess of $150,000; certain ERISA events; certain change in control 
events and the defectiveness of any liens under the secured revolving credit agreement. Obligations under the Amended Credit 
Agreement may be accelerated upon the occurrence of an event of default.

As of December 31, 2015, we were in compliance with all covenants in our Amended Credit Agreement.  A default 
under our Amended Credit Agreement could trigger the acceleration of our bank debt so that it is immediately due and payable.  Such 
default would have a material adverse effect on our liquidity, financial position and operations.

Components of Our Principal Capital Expenditures

Capital expenditures for the three years ended December 31, 2015:

Expenditure Category

Rental equipment, vehicles and shop equipment

2015

$

12,504

2014
(in thousands)
53,342
$

2013

$

43,419

The level of our expenditures will vary in future periods depending on energy market conditions and other related 
economic factors.  Based upon existing economic and market conditions, we believe that our operating cash flow and additional 
bank borrowings are adequate to fully fund our net capital expenditures requirements for 2016.  We also believe we have significant 
flexibility with respect to our financing alternatives and adjustment of our expenditure plans if circumstances warrant.  When 
considered  in  relation  to  our  total  financial  capacity,  we  do  not  have  any  material  continuing  commitments  associated  with 
expenditure plans related to our current operations can be met.

Off-Balance Sheet Arrangements

From time-to-time, we enter into off-balance sheet arrangements and transactions that can give rise to off-balance sheet 
obligations.  As of December 31, 2015, the off-balance sheet arrangements and transactions that we have entered into include 
operating lease agreements and purchase agreements.  We do not believe that these arrangements are reasonably likely to materially 
affect our liquidity or availability of, or requirements for, capital resources.

We entered into a purchase agreement with a vendor in July 2008 pursuant to which we agreed to purchase up to $4.8 
million of our paint and coating requirements exclusively from the vendor.  In connection with the execution of the agreement, 
the vendor paid us a $300,000 fee which is considered to be a discount toward future purchases from the vendor.  As of  December 31, 
2015 we had met $2.7 million of this obligation.  The $300,000 payment we received is recorded as a long-term liability and will 
decrease as the purchase commitment is fulfilled.  The long-term liability remaining as of December 31, 2015 was $129,000.

Recently Issued Accounting Pronouncements

On February 25, 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 
No. 2016-02, Leases (Topic 842), as part of a joint project with the International Accounting Standards Board (“IASB”) to increase 
transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and 
disclosing key information about leasing arrangements. To satisfy the foregoing objective, the FASB is creating Topic 842, Leases, 
which supersedes Topic 840. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and 
operating leases with lease terms of more than 12 months. Additionally, this ASU will require disclosures to help investors and 
other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including 
qualitative and quantitative requirements. For public business entities, the amendments are effective for fiscal years beginning 
after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The new standard 
will be effective during our first quarter ending March 31, 2019. We are currently evaluating the potential impact this new standard 
may have on our financial statements. 

On November 20, 2015, FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740). 
ASU No. 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial 
position. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2016, including 
interim periods within those fiscal years. The new standard will be effective during our first quarter ending March 31, 2017. We 
are currently evaluating the potential impact this new standard may have on our financial statements. 

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This 
ASU requires entities measuring inventories under the first-in, first-out or average cost methods to measure inventory at the lower 
of cost or net realizable value, where net realizable value is "estimated selling prices in the ordinary course of business, less 
reasonably predictable costs of completion, disposal, and transportation." Inventory was previously required to be measured at 
the lower of cost or market value, where the measurement of market value had several potential outcomes. The provisions of this 
ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption 
is permitted provided that presentation is applied to the beginning of the fiscal year of adoption. A reporting entity may apply the 
amendment prospectively. We are currently evaluating the potential impact this new standard may have on our financial statements. 

31

 
 
 
 
 
On August 27, 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 
205-40)-Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 provides guidance 
to U.S. GAAP about management’s responsibility to evaluate whether there is a substantial doubt about an entity’s ability to 
continue as a going concern and to provide related footnote disclosures. Specifically, ASU No. 2014-15 (1) defines the term 
substantial  doubt,  (2)  requires  an  evaluation  of  every  reporting  period  including  interim  periods,  (3)  provides  principles  for 
considering the mitigating effect of management’s plan, (4) requires certain disclosures when substantial doubt is alleviated as a 
result of consideration of management’s plans, (5) requires an express statement and other disclosures when substantial doubt is 
not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued (or 
available to be issued). For public business entities, the amendments are effective for fiscal years beginning after December 15, 
2016, including interim periods within those fiscal years, with early adoption permitted. We do not expect this new standard to 
have a material impact on our financial statements. 

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), as part of a joint 
project with the International Accounting Standards Board (IASB) to clarify revenue-recognizing principles and develop a common 
revenue standard for U.S. GAAP and International Financial Reporting Standards (IFRS). ASU No. 2014-09 finalizes Proposed 
ASU Nos. 1820-100, 2011-230 and 2011-250 and is expected, among other things, to remove inconsistencies and weaknesses in 
revenue requirements and improve comparability of revenue recognition practices across entities, industries, jurisdictions and 
capital markets. In particular, the amendments in this ASU will be added to the FASB Accounting Standards Codification (FASB 
ASC) as Topic 606, Revenue from Contracts with Customers, and will supersede the revenue recognition requirements in FASB 
ASC 605, Revenue Recognition, as well as some cost guidance in FASB ASC Subtopic 605-35, Revenue Recognition-Construction-
Type and Production-Type Contracts. The core principle of this ASU is that an entity should recognize revenue to depict the transfer 
of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled 
in exchange for those goods or services. To achieve this core principle, the guidance provides that an entity should apply the 
following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligation in the contract; (3) determine 
the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue 
when, or as, the entity satisfies a performance obligation. In August 2015, the FASB issued ASU No. 2015-14 deferring the effective 
date of ASU No. 2014-09, by one year. For public entities, the amendments are effective for annual reporting periods beginning 
after December 15, 2017, including interim periods within that reporting period, and early adoption is permitted only for annual 
reporting periods beginning after December 15, 2016, including interim periods within that year. Additionally, an entity should 
apply the amendments either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect 
of initially applying this ASU recognized at the date of initial application. If an entity elects the latter, transition method, then it 
must also provide the additional disclosures in reporting periods that include the date of initial application of (1) the amount by 
which each financial statement line item is affected in the current reporting period, as compared to the guidance that was in effect 
before the change, and (2) an explanation of the reasons for significant changes. The new standard will be effective during our 
first quarter ending March 31, 2018. We are currently evaluating the new standard to determine which reporting option allows us 
to report the most meaningful information and are still evaluating the potential impact this new standard may have on our financial 
statements.

Environmental Regulations

Various  federal,  state  and  local  laws  and  regulations  covering  the  discharge  of  materials  into  the  environment,  or 
otherwise relating to protection of human safety and health and the environment, affect our operations and costs.  Compliance 
with these laws and regulations could cause us to incur remediation or other corrective action costs or result in the assessment of 
administrative, civil and criminal penalties and the issuance of injunctions delaying or prohibiting operations.  In addition, we 
have acquired certain properties and plant facilities from third parties whose actions with respect to the management and disposal 
or release of hydrocarbons or other wastes were not under our control.  Under environmental laws and regulations, we could be 
required to remove or remediate wastes disposed of or released by prior owners.  In addition, we could be responsible under 
environmental laws and regulations for properties and plant facilities we lease, but do not own.  Compliance with such laws and 
regulations increases our overall cost of business, but has not had a material adverse effect on our operations or financial condition.  It 
is not anticipated, based on current laws and regulations, that we will be required in the near future to expend amounts that are 
material in relation to our total expenditure budget in order to comply with environmental laws and regulations but such laws and 
regulations are frequently changed and we are unable to predict the ultimate cost of compliance.  We also could incur costs related 
to the cleanup of sites to which we send equipment and for damages to natural resources or other claims related to releases of 
regulated substances at such sites.

ITEM 7A. 
Commodity Risk

  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Our commodity risk exposure is the pricing applicable primarily to  natural gas production and to lesser extent oil 
production.  Realized commodity prices received for such production are primarily driven by the prevailing worldwide price for 
crude oil and spot prices applicable to natural gas.  Depending on the market prices of oil and natural gas, companies exploring 
for such resources may cancel or curtail their drilling programs, thereby reducing demand for our equipment and services.

Financial Instruments and Debt Maturities

Our financial instruments consist of cash and cash equivalents, trade receivables, accounts payable and our line of 
credit.  The carrying amounts of cash and cash equivalents, trade receivables, and accounts payable approximate fair value because 
of  the  short-term  nature  of  the  instruments.  The  fair  value  of  our  bank  borrowings  approximate  the  carrying  amounts  as  of 
December 31, 2015 and 2014, and were determined based upon interest rates currently available to us.

Customer Credit Risk

We are exposed to the risk of financial non-performance by our customers.  Our ability to collect on rentals and sales 
to our customers is dependent on the liquidity of our customer base.  To manage customer credit risk, we monitor credit ratings 
of our customers.  Unless we are able to retain our existing customers, or secure new customers if we lose one or more of our 
significant customers, our revenue and results of operations would be adversely affected.  At December 31, 2015, we had two 
customers that accounted for a total of approximately 35% of our accounts receivable.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of our management, including our 
President and Chief Executive Officer and our Vice President and Chief Financial Officer, of the effectiveness of the design of 
our “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange 
Act of 1934, as amended or, the “Exchange Act”) as of December 31, 2015, pursuant to Exchange Act Rule 13a-15.  Based upon 
that evaluation, the President and Chief Executive Officer and our Principal Accounting Officer have concluded that our disclosure 
controls and procedures as of December 31, 2015, are effective to ensure that information required to be disclosed by us in the 
reports filed or submitted by us under the Exchange Act is recorded, processed, summarized, and reported within the time periods 
specified in the SEC’s rules and forms and include controls and procedures designed to ensure that information required to be 
disclosed by us in such reports is accumulated and communicated to our management, including our principal executive and 
financial officers as appropriate to allow timely decisions regarding required disclosures.  Due to the inherent limitations of control 
systems, not all misstatements may be detected.  Those inherent limitations include the realities that judgments in decision-making 
can be faulty and that breakdowns can occur because of simple errors or mistakes.  Additionally, controls could be circumvented 
by the individual acts of some persons or by collusion of two or more people.  Our controls and procedures can only provide 
reasonable, not absolute, assurance that the above objectives have been met.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation 
required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last quarter that have materially 
affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our  management,  including  the  President  and  Chief  Executive  Officer  and  our  Principal Accounting  Officer,  is 
responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and 
15d-15(f) under the Exchange Act.  Our internal control system is designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles.  Our internal control over financial reporting includes those policies and procedures that:

• 

• 

• 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 
of our assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance  with  accounting  principles  generally  accepted  in  the  United  States  of America,  and  that  our  receipt  and 
expenditures are being made only in accordance with authorizations of management and our Board of Directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of 
our assets that could have a material effect on the financial statements.

All internal control systems, no matter how well designed, have inherent limitations.  A system of internal control may 
become inadequate over time because of changes in conditions or deterioration in the degree of compliance with the policies or 
procedures.  Therefore, even those systems  determined to  be  effective can  provide  only reasonable assurance with respect to 
financial statement preparation and presentation.

Our management assessed the effectiveness of our internal control over financial reporting as December 2015 using the 
criteria set forth by the Commission of Sponsoring Organizations of the Treadway Commission (COSO) in their  Internal Control-
Integrated Framework (2013).  Based on this assessment, our management concluded that, as of December 31, 2015, our internal 
control over financial reporting was effective.

Pursuant to the Section 404 of the Sarbanes-Oxley Act of 2002, we have included a report of management's assessment 
of the effectiveness of our internal controls as part of this annual report on Form 10-K for the fiscal year December 31, 2015. BDO 
USA,  LLP,  our  independent  registered  public  accounting  firm,  has  issued  an  attestation  report  dated  March  11,  2016  on  the 
effectiveness of internal control over financial reporting.  That report is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders
Natural Gas Services Group, Inc.
Midland, Texas

We have audited Natural Gas Services Group, Inc.’s (the “Company”) internal control over financial reporting as of December 31, 
2015, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (the COSO criteria).  The Company's management is responsible for maintaining 
effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial 
reporting included in the accompanying “Item 9A. Management’s Report on Internal Control Over Financial Reporting."  Our 
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal 
control over financial reporting was maintained in all material respects.  Our audit included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures 
as we considered necessary in the circumstances.  We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (1) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that 
could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Natural Gas Services Group, Inc. maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
balance sheets of Natural Gas Services Group, Inc. as of December 31, 2015 and 2014 and the related statements of income, 
stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2015 and our report dated March 
11, 2016 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
Natural Gas Services Group, Inc.
Midland, Texas

We have audited the accompanying balance sheets of Natural Gas Services Group, Inc. (the "Company") as of December 31, 2015
and 2014 and the related statements of income, stockholders' equity and cash flows for each of the three years in the period ended 
December 31, 2015. These financial statements are the responsibility of the Company’s management.  Our responsibility is to 
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial 
statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements,   assessing the accounting principles used and significant estimates made by management, 
as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our 
opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Natural 
Gas Services Group, Inc. as of December 31, 2015 and 2014 and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United 
States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Natural Gas Services Group, Inc.’s, internal control over financial reporting as of December 31, 2015, based on criteria established 
in  Internal  Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission, and our report dated March 11, 2016 expressed an unqualified opinion thereon.

NATURAL GAS SERVICES GROUP INC.
NOTES TO FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Organization and Principles of Consolidation

These notes apply to the financial statements of Natural Gas Services Group, Inc.  (the "Company", “NGSG”, "Natural 
Gas Services Group", "we" or "our") (a Colorado corporation).  Natural Gas Services Group, Inc. was formed on December 17, 
1998 for the purposes of combining the operations of certain manufacturing, service and leasing entities.

Nature of Operations

Natural Gas Services Group, Inc. is a leading provider of small to medium horsepower compression equipment to the 
natural gas industry.  We focus primarily on the non-conventional natural gas production business in the United States (such as 
coal bed methane, gas shale, tight gas and oil shale).  We manufacture, fabricate and rent natural gas compressors that enhance 
the production of natural gas wells.  NGSG provides maintenance services for its natural gas compressors.  In addition, we sell 
custom fabricated natural gas compressors to meet customer specifications dictated by well pressures, production characteristics 
and particular applications.  We also manufacture and sell flare systems for oil and natural gas plant and production facilities.

Use of Estimates

The preparation of our financial statements in conformity with accounting principles generally accepted in the United 
States of America requires our management to make estimates and assumptions that affect the amounts reported in these financial 
statements and accompanying notes.  Actual results could differ from those estimates.  Significant estimates include fixed asset 
lives, bad debt allowance and the allowance for inventory obsolescence.  It is at least reasonably possible these estimates could 
be revised in the near term and the revisions could be material.

Cash Equivalents

For purposes of reporting cash flows, we consider all short-term investments with an original maturity of three months

or less to be cash equivalents.

Accounts Receivable

Our trade receivables consist of customer obligations for the sale of compressors and flare systems due under normal 
trade terms, and operating leases for the use of our natural gas compressors.  The receivables are not collateralized except as 
provided for under lease agreements.  However, we typically require deposits of as much as 50% or use of progress payments for 
large custom sales contracts.  We extend credit based on management's assessment of the customer's financial condition, receivable 
aging, customer disputes and general business and economic conditions.   The allowance for doubtful accounts was $833,000 and 
$507,000 at December 31, 2015 and 2014, respectively. Management believes that the allowance is adequate; however, actual 
write-offs may exceed the recorded allowance.

Revenue Recognition

Revenue from the sales of custom and fabricated compressors, and flare systems is recognized when title passes to the 
customer, the customer assumes risks and rewards of ownership, collectability is reasonably assured and delivery occurs as directed 
by our customer. From time to time, we have customers that request units and flares to be built under a bill and hold arrangement. 
In order to recognize revenue under a bill and hold arrangement the following criteria was met: risk of ownership was passed to 
the customer, customer made a fixed commitment to purchase the goods, the buyer requested the bill and hold, there was a fixed 
schedule for delivery, we no longer had any specific performance obligations, the purchase was segregated at our facility and the 
equipment was complete and ready to ship. As of December 31, 2015 we recognized revenue of $4 million under these bill and 
hold arrangements. Exchange and rebuilt compressor revenue is recognized when both the replacement compressor has been 
delivered and the rebuild assessment has been completed.  Revenue from compressor service and retrofitting services is recognized 
upon providing services to the customer.  Maintenance agreement revenue is recognized as services are rendered.  Rental revenue 
is recognized over the terms of the respective rental agreements.  Deferred income represents payments received before a product 
is shipped.  Revenue from the sale of rental units is included in sales revenue when equipment is shipped or title is transferred to 
the customer. 

F- 6

Major Customers and Concentration of Credit Risk

Sales and rental income to Devon Energy Production, Inc. ("Devon") and Occidental Permian, LTD. ("Oxy")  in 2015
amounted to 21% and 10% of revenue, respectively. Sales and rental income to Devon and EOG Resources, Inc. ("EOG") in 2014
amounted to 18% and 15% of revenue, respectively. Sales and rental income to EOG and Devon in 2013 amounted to 18% and 
15% of revenue. No other single customer accounted for more than 10% of our revenues in 2015, 2014 or 2013. Oxy and Devon 
amounted to 25%, and 10%, respectively, of our accounts receivable as of December 31, 2015. EOG, Promatcon Tepatguna and 
Oxy amounted to 20% and 18% and 14%, respectively, of our accounts receivable as of December 31, 2014. No other customers 
amounted to more than 10% of our accounts receivable as of December 31, 2015 and 2014. 

Inventory

Inventory is valued at the lower of cost or market.  The cost of inventories is determined by the weighted average 
method.  A  reserve  is  recorded  against  inventory  balances  for  estimated  obsolescence.  This  reserve  is  based  on  specific 
identification and historical experience and totaled $12,000 and $225,000 at December 31, 2015 and 2014, respectively. There 
were 7 newly completed compressor units at December 31, 2015 and none at December 31, 2014 available for sale or for use in 
our rental fleet.  At December 31, 2015 and 2014, inventory consisted of the following (in thousands):

Property and equipment is recorded at cost less accumulated depreciation.  Depreciation is computed using the straight-
line method over the estimated useful lives of the assets, which range from three to forty years.  Rental equipment has an estimated 
useful life of fifteen years.

Gains  and  losses  resulting  from  sales  and  dispositions  of  property  and  equipment  are  included  in  current 

operations.  Maintenance and repairs are charged to operations as incurred.

Goodwill

Goodwill  represents  the  cost  in  excess  of  fair  value  of  the  identifiable  net  assets  acquired.  Goodwill  is  tested  for 
impairment annually or whenever events indicate impairment may have occurred. Due to the weakening oil price environment, 
we performed a goodwill impairment test as of June 30, 2015 and our annual goodwill impairment test was performed in the fourth 
quarter of 2015. We experienced no impairment of goodwill during the years ended December 31, 2015 or 2014.

F- 7

 
Intangibles

At December 31, 2015, NGSG had intangible assets, which relate to developed technology and a trade name. The 
carrying  amount  net  of  accumulated  amortization  at  December 31,  2015  and  2014  was  $1.8  million  and  $1.9  million
respectively.  Developed technology is amortized on a straight-line basis with a useful life of 20 years, with a weighted average 
remaining life of approximately nine years as of December 31, 2015.  Amortization expense recognized in each of the years ending 
December 31, 2015, 2014, and 2013 was $125,000,  $125,000 and $130,000 respectively. Estimated amortization expense for the 
years 2016-2024 is $125,000 per year. NGSG has an intangible asset with a gross carrying value of $654,000 at December 31, 
2015 related to the trade name of SCS which was acquired in our acquisition of Screw Compression Systems in January 2005.  This 
asset is not being amortized as it has been deemed to have an indefinite life. 

The following table represents the identified intangible assets by major asset class (in thousands):

Our policy is to periodically review intangibles for impairment through an assessment of the estimated future cash 
flows related to such assets.  In the event that assets are found to be carried at amounts in excess of estimated undiscounted future 
cash flows, then the assets will be adjusted for impairment to a level commensurate with a discounted cash flow analysis of the 
underlying  assets.  Based  upon  our  analysis,  we  experienced  no  impairment  of  intangible  assets  during  the  years  ended 
December 31, 2015 or 2014.

Warranty

We accrue amounts for estimated warranty claims based upon current and historical product warranty costs and any 
other related information known.  The warranty reserve was $103,000 and $0 for December 31, 2015 and 2014, respectively, and 
is included in accrued liabilities on the balance sheet. 

Financial Instruments and Concentrations of Credit Risk

We invest our cash primarily in deposits and money market funds with commercial banks.  At times, cash balances at 

banks and financial institutions may exceed federally insured amounts.

Per Share Data

Basic earnings per common share is computed using the weighted average number of common shares outstanding 
during the period.  Diluted earnings per common share is computed using the weighted average number of common stock and 
common stock equivalent shares outstanding during the period.  There were anti-dilutive securities in 2015 and 2014 and none in  
2013.

In the year-ended December 31, 2015, options to purchase 107,500 shares of common stock with exercise prices ranging from 
$22.90 to $33.36 were not included in the computation of dilutive income per share, due to their antidilutive effect.

In the year-ended December 31, 2014, options to purchase 55,000 shares of common stock with exercise prices ranging from 
$30.41 to $33.36 were not included in the computation of dilutive income per share, due to their antidilutive effect.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences 
between the financial statement carrying amounts of assets and liabilities and their respective tax bases, and operating losses and 
tax credit carry-forwards.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable 
income in the years in which those temporary differences are expected to be recovered or settled.

ASC Topic 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition 
and measurement of a tax position taken or expected to be taken in a tax return.  In order to record any financial statement benefit, 
we are required to determine, based on technical merits of the position, whether it is more likely than not (a likelihood of more 
than 50 percent) that a tax position will be sustained upon examination, including resolution of any related appeals or litigation 
processes.  If that step is satisfied, then we must measure the tax position to determine the amount of benefit to recognize in the 
financial statements.  The tax position is measured at the largest amount of the benefit that is greater than 50 percent likely of 
being realized upon ultimate settlement.  We have no uncertain tax positions as of December 31, 2015 or 2014.  

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants at the measurement date under current market conditions.  ASC Topic 820 established a 
fair value hierarchy, which requires an entity to maximize the use of observable inputs when measuring fair value.  These inputs 
are categorized as follows:

Level 1- quoted prices in an active market for identical assets or liabilities;

Level 2- quoted prices in an active market for similar assets or liabilities, inputs other than quoted prices that are observable for 
similar assets or liabilities, inputs derived principally from or corroborated by observable market data by correlation or other 
means; and

Level 3- valuation methodology with unobservable inputs that are significant to the fair value measurement.

  Management believes that the fair value of our cash and cash equivalents, trade receivables, accounts payable and line 
of credit at December 31, 2015 and 2014 approximate their carrying values due to the short-term nature of the instruments or the 
use of prevailing market interest rates. 

Segments and Related Information

ASC 280-10-50, “Operating Segments”, define the characteristics of an operating segment as a) being engaged in 
business activity from which it may earn revenue and incur expenses, b) being reviewed by the company's chief operating decision 
maker  (CODM)  for  decisions  about  resources  to  be  allocated  and  assess  its  performance  and  c)  having  discrete  financial 
information.  Although we indeed look at our products to analyze the nature of our revenue, other financial information, such as 
certain costs and expenses, net income and EBITDA are not captured or analyzed by these categories.  Our CODM does not make 
resource allocation decisions or access the performance of the business based on these categories, but rather in the aggregate. 
Based on this, management believes that it operates in one business segment. 

In their analysis of product lines as potential operating segments, management also considered ASC 280-10-50-11, 

“Aggregation Criteria”, which allows for the aggregation of operating segments if the segments have similar economic 
characteristics and if the segments are similar in each of the following areas: 

•  The nature of the products and services;

•  The nature of the production processes; 

•  The type or class of customer for their products and services; 

•  The methods used to distribute their products or provide their services; and

•  The nature of the regulatory environment, if applicable.

We are engaged in the business of designing and manufacturing compressors and flares. Our compressors and flares 
are sold and rented to our customers. In addition, we provide service and maintenance on compressors in our fleet and to third 
parties.These business activities are similar in all geographic areas.  Our manufacturing  process is essentially the same for the 
entire Company and is performed in house at our facilities in Midland, Texas and Tulsa, Oklahoma.  Our customers primarily 
consist of entities in the business of producing natural gas.  The maintenance and service of our products is consistent across the 
entire Company and is performed via an internal fleet of vehicles.  The regulatory environment is similar in every jurisdiction in 
that the most impacting regulations and practices are the result of federal energy policy.  In addition, the economic characteristics 
of each customer arrangement are similar in that we maintain policies at the corporate level.

Recently Issued Accounting Pronouncements

On February 25, 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 
No. 2016-02, Leases (Topic 842), as part of a joint project with the International Accounting Standards Board (“IASB”) to increase 
transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and 
disclosing key information about leasing arrangements. To satisfy the foregoing objective, the FASB is creating Topic 842, Leases, 
which supersedes Topic 840. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and 
operating leases with lease terms of more than 12 months. Additionally, this ASU will require disclosures to help investors and 
other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including 
qualitative and quantitative requirements. For public business entities, the amendments are effective for fiscal years beginning 
after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The new standard 
will be effective during our first quarter ending March 31, 2019. We are currently evaluating the potential impact this new standard 
may have on our financial statements. 

On November 20, 2015, FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740). 
ASU No. 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial 
position. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2016, including 
interim periods within those fiscal years. The new standard will be effective during our first quarter ending March 31, 2017. We 
are currently evaluating the potential impact this new standard may have on our financial statements. 

F- 10

 
  
  
  
 
 
In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This 
ASU requires entities measuring inventories under the first-in, first-out or average cost methods to measure inventory at the lower 
of cost or net realizable value, where net realizable value is "estimated selling prices in the ordinary course of business, less 
reasonably predictable costs of completion, disposal, and transportation." Inventory was previously required to be measured at 
the lower of cost or market value, where the measurement of market value had several potential outcomes. The provisions of this 
ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption 
is permitted provided that presentation is applied to the beginning of the fiscal year of adoption. A reporting entity may apply the 
amendment prospectively. We are currently evaluating the potential impact this new standard may have on our financial statements. 

On August 27, 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 
205-40)-Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 provides guidance 
to U.S. GAAP about management’s responsibility to evaluate whether there is a substantial doubt about an entity’s ability to 
continue as a going concern and to provide related footnote disclosures. Specifically, ASU No. 2014-15 (1) defines the term 
substantial  doubt,  (2)  requires  an  evaluation  of  every  reporting  period  including  interim  periods,  (3)  provides  principles  for 
considering the mitigating effect of management’s plan, (4) requires certain disclosures when substantial doubt is alleviated as a 
result of consideration of management’s plans, (5) requires an express statement and other disclosures when substantial doubt is 
not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued (or 
available to be issued). For public business entities, the amendments are effective for fiscal years beginning after December 15, 
2016, including interim periods within those fiscal years, with early adoption permitted. We do not expect this new standard to 
have a material impact on our financial statements. 

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), as part of a joint 
project with the International Accounting Standards Board (IASB) to clarify revenue-recognizing principles and develop a common 
revenue standard for U.S. GAAP and International Financial Reporting Standards (IFRS). ASU No. 2014-09 finalizes Proposed 
ASU Nos. 1820-100, 2011-230 and 2011-250 and is expected, among other things, to remove inconsistencies and weaknesses in 
revenue requirements and improve comparability of revenue recognition practices across entities, industries, jurisdictions and 
capital markets. In particular, the amendments in this ASU will be added to the FASB Accounting Standards Codification (FASB 
ASC) as Topic 606, Revenue from Contracts with Customers, and will supersede the revenue recognition requirements in FASB 
ASC 605, Revenue Recognition, as well as some cost guidance in FASB ASC Subtopic 605-35, Revenue Recognition-Construction-
Type and Production-Type Contracts. The core principle of this ASU is that an entity should recognize revenue to depict the transfer 
of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled 
in exchange for those goods or services. To achieve this core principle, the guidance provides that an entity should apply the 
following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligation in the contract; (3) determine 
the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue 
when, or as, the entity satisfies a performance obligation. In August 2015, the FASB issued ASU No. 2015-14 deferring the effective 
date of ASU No. 2014-09, by one year. For public entities, the amendments are effective for annual reporting periods beginning 
after December 15, 2017, including interim periods within that reporting period, and early adoption is permitted only for annual 
reporting periods beginning after December 15, 2016, including interim periods within that year. Additionally, an entity should 
apply the amendments either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect 
of initially applying this ASU recognized at the date of initial application. If an entity elects the latter, transition method, then it 
must also provide the additional disclosures in reporting periods that include the date of initial application of (1) the amount by 
which each financial statement line item is affected in the current reporting period, as compared to the guidance that was in effect 
before the change, and (2) an explanation of the reasons for significant changes. The new standard will be effective during our 
first quarter ending March 31, 2018. We are currently evaluating the new standard to determine which reporting option allows us 
to report the most meaningful information and are still evaluating the potential impact this new standard may have on our financial 
statements

Reclassification of Prior Period Balances

Certain reclassifications have been made to prior period amounts to conform to the current-year presentation. These 
reclassifications had no effect on the reported results of operations.

2.  Rental Activity

We rent natural gas compressor packages to entities in the petroleum industry.  These rental arrangements are classified 
as  operating  leases  and  generally  have  original  terms  of  six  months  to  two  years  and  continue  on  a  month-to-month  basis 
thereafter. Depreciation expense for rental equipment was $21.0 million, $19.8 million and $16.4 million for the years ended

4. Retirement of Long-Lived Assets

As a result of a decline in market conditions during the first half of 2015, management reviewed our rental compressor 
units that were not of the type, configuration, make or model that our customers were demanding or that were not cost efficient 
to refurbish, maintain and operate. As a result of that review, we determined that 258 units representing total horsepower of 32,259
should be retired from our rental fleet with key components from those units being re-utilized in future unit builds and/or repairs. 
We performed an optimization review and recorded a $4.4 million loss on the retirement of rental equipment to reduce the book 
value of each unit to the estimated fair value of approximately $967,000 for the key components being kept. The retirement is 
recorded in the income statement under loss on retirement of rental equipment.

5. Credit Facility

We  have  a  senior  secured  revolving  credit  agreement  with  JP  Morgan  Chase  Bank,  N.A  (the  "Amended  Credit 
Agreement") aggregate commitment $30 million, subject to collateral availability. We also have a right to request from the lender, 
on an uncommitted basis, an increase of up to $20 million on the aggregate commitment (which could potentially increase the 
commitment amount to $50 million). 

Borrowing Base. At any time before the maturity of the Amended Credit Agreement, we may draw, repay and re-borrow amounts 
available under the borrowing base up to the maximum aggregate availability discussed above. Generally, the borrowing base 
equals the sum of (a) 80% of our eligible accounts receivable plus (b) 50% of the book value of our eligible general inventory 
(not  to  exceed  50%  of  the  commitment  amount  at  the  time)  plus  (c)  75%  of  the  book  value  of  our  eligible  equipment 
inventory.  JPMorgan Chase Bank (the “Lender”) may adjust the borrowing base components if material deviations in the collateral 
are discovered in future audits of the collateral. We had $29.5 million borrowing base availability at December 31, 2015 under 
the terms of our Amended Credit Agreement.

F- 12

 
 
 
 
 
 
Interest and Fees.  Under the terms of the Amended Credit Agreement, we have the option of selecting the applicable variable 
rate for each revolving loan, or portion thereof, of either (a) LIBOR multiplied by the Statutory Reserve Rate (as defined in the 
Amended Credit Agreement), with respect to this rate, for Eurocurrency funding, plus the Applicable Margin (“LIBOR-based”), 
or (b) CB Floating Rate, which is the Lender's Prime Rate less the Applicable Margin; provided, however, that no more than three
LIBOR-based borrowings under the agreement may be outstanding at any one time. For purposes of the LIBOR-based interest 
rate, the Applicable Margin is 1.50%. For purposes of the CB Floating Rate, the Applicable Margin is 1.25%. 

Accrued interest is payable monthly on outstanding principal amounts, provided that accrued interest on LIBOR-based 
loans is payable at the end of each interest period, but in no event less frequently than quarterly. In addition, fees and expenses 
are payable in connection with our requests for letters of credit (generally equal to the Applicable Margin for LIBOR-related 
borrowings multiplied by the face amount of the requested letter of credit) and administrative and legal costs.

Maturity . The maturity date of the Amended Credit Agreement is December 31, 2017, at which time all amounts borrowed under 
the agreement will be due and outstanding letters of credit must be cash collateralized. The agreement may be terminated early 
upon our request or the occurrence of an event of default.

Security. The obligations under the Amended Credit Agreement are secured by a first priority lien on all of our inventory and 
accounts and leases receivables, along with a first priority lien on a variable number of our leased compressor equipment the book 
value of must be maintained at a minimum of 2.00 to 1.00 commitment coverage ratio (such ratio being equal to (i) the amount 
of the borrowing base as of such date to (ii) the amount of the commitment as of such date.)

Covenants. The Amended Credit Agreement contains customary representations and warranties, as well as covenants which, among 
other things, limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions 
in excess of certain amounts; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make 
negative pledges; consolidate, merge or effect asset sales; or change the nature of our business. In addition, we also have certain 
financial covenants that require us to maintain a leverage ratio less than or equal to 2.50 to 1.00 as of the last day of each fiscal 
quarter.

Events of Default and Acceleration. The Amended Credit Agreement contains customary events of default for credit facilities of 
this size and type, and includes, without limitation, payment defaults; defaults in performance of covenants or other agreements 
contained in the loan documents; inaccuracies in representations and warranties; certain defaults, termination events or similar 
events; certain defaults with respect to any other Company indebtedness in excess of $50,000; certain bankruptcy or insolvency 
events; the rendering of certain judgments in excess of $150,000; certain ERISA events; certain change in control events and the 
defectiveness of any liens under the secured revolving credit facility.  Obligations under the Amended Credit Agreement may be 
accelerated upon the occurrence of an event of default.

As of December 31, 2015, we were in compliance with all covenants in our Amended Credit Agreement.  A default under 
our Credit Agreement could trigger the acceleration of our bank debt so that it is immediately due and payable.  Such default 
would likely limit our ability to access other credit. At December 31, 2015 our balance on the line of credit was $417,000.  Our 
weighted average interest rate for the year ended December 31, 2015 was 1.69%.

6.  Other Long-term Liabilities

At December 31,  2012, we had a long-term liability of $275,000 to Midland Development Corporation. The liability 
was fully satisfied during the quarter ended March 31, 2013. As a result of our performance under the agreement, a payment to 
Midland Development Corporation of $52,000 was made to settle the liability, resulting in a gain of $223,000, which is included 
in the other income line, in our statement of income for the year ended December 31, 2013.  

In addition, we entered into a purchase agreement with a vendor on July 30, 2008 pursuant to which we agreed to 
purchase up to $4.8 million of our paint and coating requirements exclusively from the vendor.  In connection with the execution 
of  the  agreement,  the  vendor  paid  us  a  $300,000  fee  which  is  considered  to  be  a  discount  toward  future  purchases  from  the 
vendor.  The $300,000 payment we received is recorded as a long-term liability and will decrease as the purchase commitment is 
fulfilled.  The long-term liability remaining for the purchase commitment was  $129,000 and $155,000 as of December 31, 2015
and 2014, respectively.

statement of income. 

We had a federal net operating loss carry forward of $3.2 million as of December 31, 2012, which was utilized in the 
year ended December 31, 2013. We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions.  With 
few exceptions, we are no longer subject to U.S. federal or state income tax examination by tax authorities for years before 2011.

Preferred Stock

We have a total of 5.0 million authorized preferred shares with rights and preferences as designated by the Board of 

Directors.  As of December 31, 2015 and 2014, there were no issued or outstanding preferred shares.

9. Stock-Based Compensation

Restricted Stock

 On June 3, 2014, at our annual meeting of shareholders, our shareholders approved a proposed amendment to the 2009 
Restricted Stock/Unit Plan (the "Plan") to add additional 500,000 shares of common stock to the Plan, thereby authorizing the 
issuance of up to 800,000 shares of common stock under the Plan. On March 19, 2015, the Compensation Committee awarded 
20,000 shares of restricted common stock each to G. Larry Lawrence, our CFO, and James Hazlett, our Vice President of Technical 
Services, which vest one year from the grant date. We also awarded and issued 21,968 shares of restricted common stock to our 
Board of Directors as partial payment for 2015 directors' fees. The restricted stock issued to our directors vests over one year, in 
quarterly installments, beginning March 31, 2016. In accordance with the Company's employment agreement with Stephen Taylor, 
the Company's Chief Executive Officer, the Compensation Committee reviewed his performance in determining the issuance of 
restricted common stock. Based on this review which included consideration of the Company's 2014 performance, Mr. Taylor, 
was awarded 83,590 restricted shares on January 16, 2015, which vest one year from the date of grant. Compensation expense 
related to the restricted shares was approximately $2,944,000, $2,818,000 and $1,485,000 for the years ended December 31, 2015, 
2014, and 2013, respectively. As of  December 31, 2015, there was a total of approximately $457,000 of unrecognized compensation 
expense related to the nonvested portion of these restricted shares.  This expense is expected to be recognized within one year. As 
of December 31, 2015, 361,394 shares were still available for issuance under the Plan.

A summary of all restricted stock activity as of December 31, 2015 and changes during the year then ended is presented below.

Stock Option Plan

Our 1998 Stock Option Plan (the "Stock Option Plan"), which is stockholder approved, permits the granting of stock 
options to its employees for up to 550,000 shares of common stock.  On June 16, 2009, at our annual meeting of shareholders, 
our shareholders approved a proposed amendment to the Stock Option Plan to add additional 200,000 shares of common stock to 
the Stock Option Plan, thereby authorizing the issuance of up to 750,000 shares of common stock under the Stock Option Plan.  We 
believe that such awards better align the interests of our employees with our stockholders.  Option awards are generally granted 
with an exercise price equal to the market price of our stock at the date of grant; those option awards generally vest based on three 
years of continuous service and have ten-year contractual terms.  Certain option and share awards provide for accelerated vesting 
if there is a change in control of the Company (as defined in the Stock Option Plan).  The last date that grants can be made under 
the Stock Option Plan is March 1, 2016, pending shareholder approval of an extension to the Stock Option Plan.  As of  December 31, 
2015, 93,419 shares were still available for issue under the Stock Option Plan. 

The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model that 
uses the assumptions noted in the following table.  The risk-free rate for periods within the contractual life of the option is based 
on the U.S. Treasury yield curve in effect at the time of grant.  The expected life of options granted is based on the vesting period 

F- 15

 
 
and historical exercise and post-vesting employment termination behavior for similar grants.  We use historical data to estimate 
option exercise and employee termination within the valuation model; separate groups of employees that have similar historical 
exercise behavior are considered separately for valuation purposes.

ended December 31, are as follows:

We granted one option to purchase a total of 50,000 shares to non-executive employees in April 2015 at an exercise 

price of $22.90 with a three year vesting period.

The weighted average grant date fair value of options granted during the years 2015, 2014, and 2013 was $10.33, 
$16.56, and $10.30 respectively.  The total intrinsic value, or the difference between the exercise price and the market price on 
the date of exercise, of options exercised during the years ended December 31, 2015, 2014, and 2013 was approximately $$481,000,

401(k) Plan

We offer a 401(k) Plan to all employees that have reached the age of eighteen and have completed six months of 
service.  The participants may contribute up to 100% of their salary subject to IRS limitations.  Employer contributions are subject 
to Board discretion and are subject to a vesting schedule of 20% each year after the first year and 100% after six years.  We 
contributed $387,000, $296,000, and $294,000 to the 401(k) Plan in 2015, 2014 and 2013, respectively.

Rented Facilities, Vehicles and Equipment

We lease certain of our facilities and equipment under operating leases with terms generally ranging from month-to-
month to five years.  Most leases contain renewal options.  Remaining future minimum rental payments due under these leases 
are as follows:

Legal Proceedings

From time to time, we are a party to various legal proceedings in the ordinary course of our business.  While management 
is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from these actions will not 
have a material effect on our financial position, results of operations or cash flow.  We are not currently a party to any bankruptcy, 
receivership, reorganization, adjustment or similar proceeding, and we are not aware of any other threatened litigation.
