|ITEM 11. | EXECUTIVE COMPENSATION
|-------- | ----------------------

INFORMATION ABOUT EXECUTIVE AND DIRECTOR COMPENSATION

Compensation Discussion and Analysis

This compensation discussion describes the material elements of compensation for the fiscal year ending December 31, 2009, that was
awarded to, earned by, or paid to each of our current and former executive officers identified in the Summary Compensation Table below as our named executive officers. This compensation discussion primarily focuses on the last completed fiscal year,
but we also describe certain compensation actions taken before or after the last completed fiscal year to enhance the understanding of this disclosure.

The Compensation Committee of our Board of Directors oversees our executive compensation program. In this role, the Compensation
Committee reviews and approves, or recommends for approval by the full Board, all compensation decisions relating to our executive officers. The Committee also oversees our stock-based compensation plans and programs.

Objectives and Philosophy of Our Executive Compensation Program

The objective of our executive compensation program is to align the interests of management with the interests of stockholders by tying a
substantial portion of overall compensation opportunities provided to executive officers to the achievement of business objectives and individual performance. Our policy is to offer competitive compensation packages that will permit us to attract
and retain individuals with superior abilities, and to motivate and reward such individuals on the basis of corporate performance in an appropriate fashion that is in the long-term interests of Environmental Power and its stockholders.

Our company continues to develop. As it does, we have been working to design and implement formal criteria and programs to reward
executive officers based upon an assessment of corporate, business-unit and individual performance. As a result of these efforts, in March 2008, our Compensation Committee adopted our Annual Incentive Management Plan and our Long-Term Incentive
Plan, in which our executive officers participate, in addition to various compensation plans for other employees other than our executive officers. The Annual Incentive Management Plan and the Long-Term Incentive Plan are described in more detail
below. Pursuant to these plans, we expect to evaluate corporate- and business unit-performance by reviewing the extent to which strategic and business-plan goals are met, including such factors as maintaining capital and operating budgets and timely
accomplishment of business-development objectives, as applicable. We expect to evaluate individual performance by reviewing attainment of specified personal objectives and the degree to which teamwork and our other values are fostered.

As a result of our recent efforts to formalize compensation practices, we have committed to the following compensation philosophy, to the
extent consistent with financial resources:



| |  |  | We will strive to provide competitive compensation programs that will help to attract highly qualified individuals necessary to grow our company, and
then to retain and motivate these individuals to achieve higher levels of performance.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Compensation programs will emphasize a pay-for-performance concept, in which an individuals future compensation growth and career
advancement are dependent upon maintaining and exceeding our recognized levels of quality and performance while supporting our strategic goals. Future monetary growth is dependent upon company performance as well as individual performance.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We will provide a compensation package consisting of base salary, incentives, and benefits that are consistent with similar positions in recognized
competitors and start-up/growth companies, with each component addressing individual, team and company performance, competitive conditions and our overall financial performance. Our goal is to attract the most qualified applicants to fuel our
growth. Future salary increases will be based on an individuals evaluated performance against pre-established objectives, as well as our performance and ability to pay.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Base salary programs will be will be targeted at market (50th percentile), and total cash compensation will be targeted aggressive to
market (up to the 75th percentile) in order to recognize our employees direct impact on our business goals.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Our core belief is that the opportunity to earn competitive incentives will help drive the focus of business. Competitive incentive compensation will
be based upon the achievement of expected performance targets, with upside potential tied to exceptional contribution and surpassing goals. Measurable performance goals and objectives will be developed by our executive management team and approved
by the Compensation Committee of the Board of Directors, consistent with our identified business strategies and financial objectives.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We will provide a quality and supportive work environment with challenging career opportunities and the necessary resources to enhance growth in order
to attract, retain, and motivate a highly qualified and experienced staff. Compensation programs shall encourage employees to maximize their capabilities through personal growth and job development in order to foster a culture that is team focused
and rewards both individual and business success.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This compensation philosophy will apply to all employees,
including our executive officers. We believe that this compensation philosophy will serve as the basis for the development of new or modified compensation programs and will be used as a tool to help meet identified needs relating to motivation and
retention. In practice, we expect that the implementation of this philosophy will have the following implications:



| |  |  | The marketplace must be considered with regard to establishing competitive compensation levels, including base salary, benefits and incentives. See the
discussion under Comparative Compensation Review Process and Benchmarking, below.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Employees should have the ability to earn total cash compensation above market levels based on exceptional performance. Incentive payouts, where
applicable, must be determined in a manner that is ethical, and is reflective of performance achieved against objective measures.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We must develop and maintain clear salary administration plan documents to ensure the consistent and proper application of all programs.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Except for contractual obligations, performance should be the primary determinant of salary increases and incentive bonuses. Increases should be based
on objective, quantifiable performance measures, where possible, with a minor portion based on discretionary factors so that subjectivity is limited.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Only those employees whose performance meets acceptable standards will receive increases, and the size of the increase will be dependent upon the
individuals evaluated performance.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Specific, measurable performance criteria for each job must be set on an annual basis, consistent with our strategic corporate objectives, and the
achievement of results for each criteria must be tracked, in order to improve accountability for end results due to the individuals ability to directly affect the amount of his/her salary increases.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A formal performance appraisal tool must be maintained that offers uniform, dependable evaluations that outline the desired performance expectations
and accurately reflects each employees contribution and performance, and which is monitored to make sure the program is consistently applied and equitable to all employees.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Management must be regularly trained in the use of the performance evaluation program and be held accountable for completing evaluations both
accurately and on a timely basis.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Comparative Compensation Review Process and Benchmarking

We do not believe that compensation levels should be controlled by benchmarking. However, we believe that information
regarding pay practices at other companies is useful in two respects. First, our compensation practices need to be competitive in the marketplace. Second, marketplace information is one of the many factors that we consider in assessing the
reasonableness of compensation. Accordingly, from time to time we have compared our compensation packagesincluding levels, components, and mix of compensation typeswith those of other companies in the alternative energy industry, through
reviews of survey data and information gleaned from filings of publicly traded companies and through information compiled and analyzed by others. Going forward, we intend to compare the compensation of our employees to the marketplace within two
specific peer groups: (1) alternative energy, energy development and production and water/wastewater treatment companies and (2) start-up and emerging bio-technology companies, and to perform these comparisons at least every two or three
years. In addition, we intend to identify a peer group and maintain updated job descriptions for each unique job in order to benchmark positions appropriately.

##### Table of Contents

While such information may be a useful guide for comparative purposes, we believe that a
successful compensation program also requires the application of judgment and subjective determinations of individual performance. Review of this information and these factors forms the basis of managements compensation recommendations to the
Compensation Committee and the Committees decision-making.

Use of Consultants

The Compensation Committees charter grants it the authority to retain outside advisors, including compensation consultants, and
approve their compensation. Environmental Power is obligated to pay the Compensation Committees advisors and consultants. Although management is involved in coordinating with these advisors with respect to the provision of their services,
these advisors and consultants report directly to the Compensation Committee. With respect to non-employee director compensation, the full Board of Directors has acted directly.

Thus, in 2007, the Compensation Committee and management sought the advice of outside counsel and also engaged Brian Foley &
Company, Inc., an independent executive compensation consulting firm, to advise the Committee on certain matters relating to stock-based compensation. Also in 2007, the Nominating and Corporate Governance Committee engaged Heidrick &
Struggles, a leading executive search firm, to assist it in evaluating best practices for corporate governance, including such matters as board composition, director stock ownership guidelines and related matters.

In February 2008, the Compensation Committee engaged Harry Schum, an independent compensation consultant, to assist the Compensation
Committee and management in the formulation of more formal incentive compensation programs for our executive officers as well as all other full-time employees.

We did not engage any compensation consultants in 2009.

Elements of Executive Compensation

Compensation for our executives has generally consisted of the following elements:



| |  |  | base salary;
| | - |  | ------------



| |  |  | bonuses;
| | - |  | --------



| |  |  | long-term incentive compensation via stock-based awards;
| | - |  | --------------------------------------------------------



| |  |  | health, dental, life and disability insurance and other traditional employee benefits, and executive perquisites; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Severance and change-in-control arrangements.
| | - |  | ---------------------------------------------

Historically, we have not had any formal policy or target for allocating compensation between long-term and short-term compensation,
between cash and non-cash compensation or among the different forms of non-cash compensation. Instead, the Compensation Committee, with input as requested from senior management, has determined subjectively what it believes to be the appropriate
level and mix of the various compensation components. The mix of compensation has also been impacted in many cases by the course of negotiations with the executive in question in connection with his hiring. Ultimately, the Compensation
Committees objective in allocating between annual and long-term compensation opportunities is to ensure adequate base compensation to attract and retain personnel, while providing incentives to maximize long-term value for our Company and its
stockholders. Therefore, we have provided cash compensation in the form of base salary to meet estimated competitive salary norms and, to the extent our cash position has permitted, have rewarded individual performance on an annual basis in the form
of bonus compensation. We provide non-cash compensation, principally in the form of equity-based grants such as stock options and, more recently, stock appreciation rights and restricted stock awards, which are intended to create incentives for the
achievement both of specific objectives and/or of long-term strategic goals.

In March 2008 the Compensation Committee, acting
upon the recommendations of management and Mr. Schum, adopted the compensation philosophy described above. In addition, as part of its effort to formalize our compensation practices generally, including with respect to our executives, the
Compensation Committee adopted our Annual Incentive Management Plan and Long-Term Incentive Plan.

##### Table of Contents

The purpose of the Annual Incentive Management Plan is to align the interests of management
with corporate performance goals by focusing management on the achievement of annual financial and operational objectives with competitive financial incentives. Full-time employees not participating in other incentive programs will be eligible under
the plan, with the extent of participation to be determined by position in our company. Pursuant to the plan, the board of directors, in cooperation with our executive team, will set annual corporate financial objectives. Individual performance will
also be considered, and threshold and maximum levels of performance will also be set. Under the plan, our Chief Executive Officer will have a target award of 50% of base salary; other executive officers will have target awards of 35% of base salary.
Our Chief Executive Officers award will be based 100% on the achievement of corporate goals; the other executive officers awards will be based 75% on the achievement of corporate goals, and 25% on individual performance. Particular
corporate objectives will be assigned a relative weight, as may also be the case with individual performance goals. Awards under the plan will be based on the overall level of achievement of both corporate and individual goals, and will be paid
following the audit of year-end financials. Participants in the plan must be employed at the time of payout to receive an award. The plan can be modified or terminated at any time, is strictly a guideline, and is not binding on us. The Compensation
Committee will determine awards to our Chief Executive Officer and other executives.

The Long-Term Incentive Plan was adopted
pursuant to the Compensation Committees discretion under our existing 2005 Equity Incentive Plan and 2006 Equity Incentive Plan, to set the terms and amounts of awards under such plans, subject to the limitations set forth in such plans. The
purpose of this plan is to provide a long-term incentive plan based on the financial growth of our company, to foster teamwork and an entrepreneurial spirit among participants and to provide a long-term compensation tool to motivate, reward and
retain participants. Our Chief Executive Officer, our other executive officers and those additional persons designed by our Chief Executive Officer, are eligible to participate in the Long-Term Incentive Plan. Awards pursuant to the plan are
expected to be made annually, and may be a combination of different long-term vehicles, including restricted stock awards, incentive stock options and stock appreciation rights, based upon guidelines considered by the Compensation Committee on an
annual basis. Such awards will be made under our 2005 Equity Incentive Plan or 2006 Equity Incentive Plan, and awards pursuant to the Long-Term Incentive Plan will be subject to the terms the equity incentive plan under which they are granted,
including any limitations on awards set forth therein. Awards pursuant to the plan generally will vest in three substantially equal annual installments beginning on the first anniversary of the grant date. The value of such awards will be determined
based on the fair market value at the time of grant, utilizing a modified Black-Scholes methodology where appropriate. The target value of each annual award (as a percentage of base salary) will be established by the Compensation Committee for our
Chief Executive Officer, will be 30% for the other executive officers, and will be discretionary for any other employees designated for participation in the plan by our Chief Executive Officer. All awards will vest in full upon the death of total
disability of a participant, or upon a change in control of our company, and will be forfeited, whether or not vested, upon any termination for cause. Awards vesting upon death or disability are to be paid or exercised within 12 months following
such event. The Long-Term Incentive Plan can be modified or terminated at any time, is strictly a guideline, and is not binding on us. The Compensation Committee will determine awards to our Chief Executive Officer and other executives.

Base Salary.Salary for our executives is generally set by reviewing compensation levels for comparable positions in the market,
as described above, and the historical compensation levels of our executives. Salaries may then be adjusted from time to time, based upon market changes, actual corporate and individual performance and promotions or changes in responsibilities. Base
salaries and other elements of compensation may also be mandated by the terms of employment and other agreements entered into with our executives, as described under Information about Executive and Director CompensationEmployment and
Severance Agreements. In such cases, base salaries have at first been determined by arms-length negotiations with these executives, generally in connection with their initial hiring. Going forward, we will continue to seek to set salaries that
are competitive with the marketplace, recognizing the skill and experience of each executive, his or her level of performance, and his or her responsibilities as compared to similarly situated employees at competing firms. While it will be our
primary objective to offer and maintain base salaries that are competitive with the marketplace, we will reserve the right to pay premium base salaries to secure the services of individuals with certain skill sets or to fill positions in key markets
that are vital to our business objectives.

Bonuses. Bonuses, as well as any annual increases in salaries, are expected to be
based on actual corporate and individual performance compared to targeted performance criteria and various subjective performance criteria. Given what we believe are competitive base salaries, as well as our stage of development and cash position,
we generally have not paid cash bonuses to our top executives from 2002 through 2006. We did, however, pay bonuses to our executives in respect of 2007, based on their individual performance. Due to our companys financial condition, no bonuses
were paid in respect of 2008, and no bonuses will be paid in respect of 2009. Going forward, we expect to pay bonuses based upon criteria and corporate and individual performance goals established in accordance with the Annual Incentive Management
Plan described above, subject to the availability of cash resources to do so. The objective of the Annual Incentive Management Plan will be to:



| |  |  | reward participants for achievement of short term financial and operating plan business goals;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | establish goals that are challenging but attainable and linked to corporate, division and individual objectives based on the ability of the participant
to influence results;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | leverage award opportunities to incent over-achievement of the operating plan objectives; and
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | provide competitive cash opportunity versus the marketplace
| | - |  | -----------------------------------------------------------

We intend to communicate the annual incentive opportunities under this plan, and the accomplishments necessary to achieve these incentives, to each
participating employee early in each plan year. Notwithstanding the adoption of the Annual Incentive Management Plan in early 2008, while specific performance goals for 2008 were initially identified, the goal setting process was
hampered by quickly changing circumstances and deteriorating financial market conditions, which resulted in a shift in the Companys priorities. These conditions persisted into 2009, and in 2009 the Companys financial condition also
deteriorated. As a result, specific performance goals for 2008 and 2009 were not implemented.

Long-Term Incentive
Compensation via Stock-Based Awards. Compensation for executive officers also includes the long-term incentives afforded by stock options and other equity-based awards. Our stock option and equity-based award program is designed to align the
long-term interests of our employees and our stockholders and assist in the retention of executives. The size of stock-based awards is generally intended to reflect the executives position and the executives expected contributions. In
2009, we made stock-based awards in accordance with the terms of the Long-Term Incentive Plan described above. This compensation plan is designed to accomplish several objectives:



| |  |  | focus participants on the strategic plan performance objectives that are critical to the success of the company over a three-year period, which
objectives are linked to the achievement of business and financial goals that are designed to create value for shareholders;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | encourage retention of participants through reward opportunities that require continued service; and
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | encourage teamwork and one company focus by employees regardless of their business unit and reward sustained contribution for attainment of
strategic objectives.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------

As this plan is based on total company strategic results, the participation is limited to those whose
actions play a direct role in the long-term success of the company, including our executive officer and others designated by our Chief Executive Officer.

Insurance, Other Employee Benefits and Perquisites. We maintain broad-based benefits and perquisites that are provided to all
employees, including health insurance, life and disability insurance, dental insurance and a 401(k) plan. Under our 401(k) plan, so long as the employee is employed through the last day of the year in question, we generally make a matching 401(k)
contribution of 50% of the employees contribution, up to 6% of the employees salary for the year, with a maximum matching contribution of $7,500. In 2009 we did not make a matching corporate contribution. In addition, we provide certain
perquisites to executives, which are generally detailed in their employment agreements or offer letters. Going forward, we expect to offer supplemental benefits and perquisites to designated executives, which supplement broad-based benefit programs.
The objectives of this supplemental benefits and perquisites program will be to:



| |  |  | Provide executives with competitive benefits and perquisites versus the marketplace;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Replace benefits that are restricted due to ERISA and/or Internal Revenue Code limitations;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Attract and retain experienced senior executives;
| | - |  | -------------------------------------------------

| |  |  | Assist executives in accomplishing job responsibilities; and
| | - |  | ------------------------------------------------------------



| |  |  | Supplement executives retirement benefits.
| | - |  | -------------------------------------------

Severance and Change-in-Control Arrangements.Compensation for executive officers also includes severance and change-in-control
arrangements, which are generally reflected in the employment agreements for such officers. These arrangements, like other elements of executive compensation, are structured with regard to practices at comparable companies for similarly-situated
officers and in a manner we believe is likely to attract and retain high quality executive talent. Changes to existing severance arrangements are also sometimes negotiated with departing executives in exchange for transition services and/or general
releases. The severance and change-in-control arrangements currently in place with our current executive officers are described in greater detail in this section under the headings Employment and Severance Arrangements, and
Summary of Potential Payments Upon Termination or Change of Control.

Other Corporate Policies
Relating to Executive Compensation

Role of Executive Officers in Determining or Recommending Executive and Director
Compensation. Management plays an important role in support of the Compensation Committees determination of executive compensation. The most significant aspects of managements role are:



| |  |  | evaluating key-employee performance;
| | - |  | ------------------------------------



| |  |  | recommending business performance targets and objectives; and
| | - |  | -------------------------------------------------------------



| |  |  | recommending salary levels and stock-based awards.
| | - |  | --------------------------------------------------

Our President and Chief Executive Officer assists the chair of the Compensation Committee in establishing the agenda for Committee
meetings. Management also prepares meeting information for each Compensation Committee meeting. At the Committees request, our President and Chief Executive Officer also participates in Compensation Committee meetings to provide input if and
as sought by the Committee, including but not limited to:



| |  |  | background information regarding our strategic objectives and progress toward the attainment of those objectives;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | information on the performance of the senior executive officers; and
| | - |  | --------------------------------------------------------------------



| |  |  | compensation recommendations as to senior executive officers other than the Chief Executive Officer.
| | - |  | ----------------------------------------------------------------------------------------------------

Ultimately, however, all executive compensation decisions are made, or recommended to the Board of Directors, by the Compensation
Committee, which makes such decisions and recommendations after considering managements recommendations, available market data, and, in some cases, input from outside advisors to the Committee. In doing so the Committee engages in
deliberations in executive session without the presence of the Chief Executive Officer or any other members of management.

The forms and amounts of non-employee director compensation in 2009 were unchanged from those set in 2007, which were determined by the
full Board of Directors following a review of data provided by Heidrick & Struggles, as described above. However, in September 2008, the Board unanimously directed management to defer payment of cash compensation due to Board members until
further notice, in order to conserve cash. We have been accruing these amounts as they become due.

Impact of Tax Treatment
on Compensation Decisions. Section 162(m) of the Internal Revenue Code of 1986, as amended, generally disallows a tax deduction for compensation in excess of $1.0 million paid to our chief executive officer and our four other most highly
paid executive officers. Qualifying performance-based compensation is not subject to the deduction limitation if specified requirements are met. We periodically review the potential consequences of Section 162(m) and generally
intend to structure our executive compensation to comply with Section 162(m). However, the Compensation Committee may, in its judgment, authorize compensation payments that do not comply with the exemptions in Section 162(m) when it
believes that such payments are appropriate to attract and retain executive talent.

Security Ownership Requirements or
Guidelines.While we believe it is important for our executives to have an equity stake in our company in order to help align their interests with those of our stockholders, we do not have any equity ownership guidelines for our executive
officers, other than as contemplated by the Long-Term Incentive Plan. We also do not have any equity ownership guidelines for our non-employee directors. However, board

members and executive officers are encouraged to acquire, during open trading windows, shares of our common stock to the extent consistent with their individual economic circumstances, and
directors and executive officers have done so.

Discussion of Specific Compensation Arrangements for 2009

On August 19, 2009, the Compensation Committee approved the following compensation arrangements with our
executive officers:

Awards under Long-term Incentive Plan

The Compensation Committee approved combined awards of stock appreciation rights and restricted stock to the Companys executive
officers. Pursuant to the guidelines set forth in our 2008 Long-Term Incentive Plan, in the case of Mr. Kessel the award reflects a value of 65% of his salary in order to assure maximum alignment with shareholder interests. The stock
appreciation rights were awarded under the our 2006 Equity Incentive Plan, each of which has an exercise price of $0.55 per share, the closing price of the our common stock as reported on The Nasdaq Capital Market on the date of grant, which the
Committee determined to be the fair market value of a share of our common stock on the date of grant. The Compensation Committee also made restricted stock awards under our 2006 Equity Incentive Plan, at a purchase price of $0.01 per share. The
Compensation Committee chose a vesting-schedule of one-third per year over a three-year period, with the first installment vesting on August 19, 2010, for both the stock appreciation rights and the restricted stock awards, with both the
stock appreciation rights and restricted stock awards vesting in full upon a change in control:



|                  |  |                                 |  |                            |  |

The foregoing awards are reflected in
more detail in the tables below.

Compensation Policies and Practices as They Relate to Risk Management

We believe that the design of our compensation policies and practices for our employees is relatively straightforward, strikes an
appropriate balance between the achievement of short-term objectives and the achievement of long-term value and does not encourage the taking of undue risks. Therefore, given this design, and the nature of our business activities, we do not believe
that risks, if any, arising from such policies and practices are reasonably likely to have a material adverse effect on our business.

calculated in accordance with FASB ASC Topic 718, using a Black-Scholes option-pricing model employing certain variables and related assumptions, including stock price volatility. The amounts shown in this column are, therefore, projections that do
not necessarily reflect the actual cash compensation to be received by the option holder upon exercise of the option or SAR. The assumptions we used to calculate these amounts are discussed in Note K to our consolidated financial statements included

at an exercise price of $6.30 per share. This option vested only if our common stock closes at a price per share equal to or in excess of $10.00 on or prior to December 31, 2007. As this condition was not satisfied, this option did not vest and
terminated by its terms.

Stock Ownership Information

Beneficial Ownership of Common Stock

The following table sets forth information regarding beneficial ownership of our common stock as of February 28, 2010 by:



| |  |  | each person, entity or group of affiliated persons or entities known to us to be the beneficial owner of more than 5% of the outstanding shares of our
common stock;

| |  |  | all of our directors and executive officers as a group.

Beneficial ownership is determined in accordance with the applicable rules of the SEC and includes voting or investment power with
respect to shares of our common stock. Shares of common stock issuable under stock options and warrants that are currently exercisable or exercisable within 60 days of February 28, 2010 are deemed to be beneficially owned by the person holding
the option or warrant for purposes of calculating the percentage ownership of that person but are not deemed outstanding for purposes of calculating the percentage ownership of any other person. The information set forth below is not necessarily
indicative of beneficial ownership for any other purpose, and the inclusion of any shares deemed beneficially owned in this table does not constitute an admission of beneficial ownership of those shares.

|(3) | Based in part on a Schedule 13G filed by Mr. Brecken and Brecken Capital, LLC on August 8, 2007. Mr. Brecken and Brecken Capital, LLC have an address of
346 Hartshorn Drive, Short Hills, NJ 07078. The number of shares of series A preferred stock beneficially owned is comprised of 9,400 shares of series A preferred stock held Mr. Brecken personally and 46,848 shares of series A preferred stock
held by Brecken Capital Management, LLC. These stockholders also hold warrants to purchase 46,967 and 234,273 shares of our common stock, respectively. The terms of the series A preferred stock and the warrants held by these stockholders provide
that these stockholders may not convert shares of series A preferred stock, or exercise warrants, if, after giving effect to such conversion or exercise, either stockholder, together with its affiliates, would beneficially own more than 4.99% of the
outstanding shares of our common stock. The foregoing beneficial ownership limitation may be waived by each stockholder, at its election, upon not less than 61 days prior notice to us, to change the limitation to 9.99% of the number of shares
of the common stock outstanding immediately after giving effect to the issuance of shares of common stock upon conversion of series A preferred stock or exercise of warrants held by such stockholder. Thereafter, the 9.99% limitation may not be
waived. We believe that Mr. Brecken is also the owner of 559,634 shares of our common stock. Mr. Brecken is the Managing Director of Brecken Capital, LLC, which is the general partner of Brecken Capital Management Fund LLC; both
Mr. Brecken and Brecken Capital, LLC may be deemed to beneficially own the shares held by Brecken Capital Management Fund LLC, insofar as they exercise voting and investment authority with respect to such shares.

|ITEM 13. | CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE
|-------- | -------------------------------------------------------------------------

Employment and Retirement Agreements

We have entered into employment and retirement arrangements with certain of our executive officers, former executive officers and
directors. For additional information regarding these agreements, see Information About Executive and Director CompensationEmployment, Transition, Retirement, Consulting and Severance Agreements appearing in Part III, Item 11
of this report. Except for such agreements and the other compensation arrangements described in this Form 10-K/A, we did not enter into any transactions with related persons within the meaning of Item 404 of Regulation S-K during the fiscal
year ended December 31, 2009 in which the amount involved exceeded $120,000.

Policies and Procedures Regarding
Review, Approval or Ratification of Related Person Transactions

In March 2007, our Board of Directors adopted written
policies and procedures for the review of any transaction, arrangement or relationship in which we are a participant, the amount involved exceeds $120,000 and one of our executive officers, directors, director nominees or 5% stockholders (or their
immediate family members), each of whom we refer to as a related person, has a direct or indirect material interest.

If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a related person
transaction, the related person must report the proposed related person transaction to our General Counsel, who we refer to as our chief legal officer. The policy calls for the proposed related person transaction to be reviewed and, if deemed
appropriate, approved by our Audit Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the Audit Committee will review, and, in its
discretion, may ratify the related person transaction. The policy also permits the chair of the Audit Committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to
ratification by the Audit Committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.

A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the Audit Committee
after full disclosure of the related persons interest in the transaction. As appropriate for the circumstances, the Audit Committee will review and consider:



| |  |  | the related persons interest in the related person transaction;
| | - |  | ----------------------------------------------------------------



| |  |  | the approximate dollar value of the amount involved in the related person transaction;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the approximate dollar value of the amount of the related persons interest in the transaction without regard to the amount of any profit or loss;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | whether the transaction was undertaken in the ordinary course of our business;
| | - |  | ------------------------------------------------------------------------------



| |  |  | whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the purpose of, and the potential benefits to us of, the transaction; and
| | - |  | -------------------------------------------------------------------------



| |  |  | any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material
to investors in light of the circumstances of the particular transaction.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Audit Committee may approve
or ratify the transaction only if the Committee determines that, under all of the circumstances, the transaction is in, or is not in conflict with, our best interests. The Audit Committee may impose any conditions on the related person transaction
that it deems appropriate.



23



---

##### Table of Contents

In addition to the transactions that are excluded by the instructions to the Securities and
Exchange Commissions related person transaction disclosure rules, our Board of Directors has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not
related person transactions for purposes of this policy:



| |  |  | interests arising solely from the related persons position as an executive officer of another entity (whether or not the person is also a
director of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, (b) the related person and his or her
immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction, and (c) the amount involved in the transaction equals less than the greater of
$200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a transaction that is specifically contemplated by provisions of our charter or bylaws.
| | - |  | ---------------------------------------------------------------------------------------

The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation
Committee in the manner specified in its charter.

There were no related person transactions presented for review in 2009.

Board Determination of Independence

Under applicable rules of The NASDAQ Stock Market LLC, a director will only qualify as an independent director if, in the
opinion of our board of directors, that person does not have a material relationship with our company which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our board of directors has
determined that none of Messrs. Ballentine, Cooper, Kessner, Schumacher, Weisberg or Hatamiya has a material relationship with our company which would interfere with the exercise of independent judgment in carrying out the responsibilities of a
director, and therefore, that each of these directors is independent within the meaning of Rule 4200(a)(15) of the NASDAQ Marketplace Rules. In addition, none of the current members of our board of directors, other than Mr. Kessel,
is an employee of Environmental Power or any of its subsidiaries. Furthermore, the board expects that Messrs. Cresci and Tejwani may become independent within the next couple of years if they remain on our board.
