Executive Officers

Information regarding our
executive officers may be found under the caption Executive Officers of the Registrant appearing at the end of Part I of our Annual Report on Form 10-K for the year ended December 31, 2006, to which this Form 10-K/A relates. Such
information is incorporated herein by reference.

Audit Committee

We have a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. The members of the Audit Committee for 2006 were Messrs. Cooper, Weisberg and
Hatamiya and Jessie J. Knight, Jr., who resigned from our Board of Directors in December 2006. The current members of the Audit Committee are Messrs. Cooper, Weisberg and Hatamiya. Mr. Cooper serves as chair of the Audit Committee.

Audit Committee Financial Expert

The Board of
Directors has determined that John R. Cooper is, and has designated Mr. Cooper as, the Audit Committee Financial Expert as defined by Item 407(d)(5)(ii) of Regulation S-K of the Exchange Act and determined that he is
independent within the meaning of Item 407(a) of Regulation S-K of the Exchange Act.

Director Nominees

The process followed by the Nominating and Corporate Governance Committee to identify and evaluate director candidates includes requests to Board members
and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the Committee and the Board of Directors.

In considering whether to recommend any particular candidate for inclusion in the Board of Directors slate of recommended director
nominees, the Nominating and Corporate Governance Committee applies certain criteria, including:



| |  |  | the candidates honesty, integrity and commitment to high ethical standards;
| | - |  | ----------------------------------------------------------------------------



| |  |  | demonstrated financial and business expertise and experience;
| | - |  | -------------------------------------------------------------

##### Table of Contents

| |  |  | understanding of our company, its business and its industry;
| | - |  | ------------------------------------------------------------



| |  |  | actual or potential conflicts of interest; and
| | - |  | ----------------------------------------------



| |  |  | the ability to act in the interests of all stockholders.
| | - |  | --------------------------------------------------------

The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is a prerequisite for each prospective nominee. We believe that the backgrounds and
qualifications of our directors, considered as a group, should provide a significant breadth of experience, knowledge and abilities that will allow our Board of Directors to fulfill its responsibilities.

The Nominating and Corporate Governance Committee will consider director candidates recommended by
stockholders or groups of stockholders who have owned more than 5% of our common stock for at least a year as of the date the recommendation is made. Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for
consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation
has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to the Nominating and Corporate Governance Committee, c/o Corporate Secretary, Environmental Power Corporation, One Cate
Street, 4thFloor, Portsmouth, New Hampshire 03801. Assuming that appropriate biographical and background material
has been provided on a timely basis, the Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others. We will
generally consider stockholder nominations for a given years annual meeting of stockholders to be timely if they are received no later than 120 days before the day of the year that the proxy statement relating to the prior years annual
meeting of stockholders is dated or, in the event the date of the annual meeting in question changes by more than 30 days from the day of the year on which the prior years annual meeting is held, a reasonable time before we print and send our
proxy materials for the annual meeting in question.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our directors, executive officers and the holders of more than 10% of our common stock
to file with the SEC initial reports of ownership of our common stock and other equity securities on a Form 3 and reports of changes in such ownership on a Form 4 or Form 5. Officers, directors and 10% stockholders are required by SEC regulations to
furnish us with copies of all Section 16(a) forms they file. To our knowledge, based solely upon a review of the copies of such forms furnished to us for the year ended December 31, 2006, and the information provided to us by those persons
required to file such reports, no such person failed to file the forms required by Section 16(a) of the Exchange Act on a timely basis, except as follows:



| |  |  | on May 8, 2006, Lon Hatamiya, a member of our Board of Directors, filed a late Form 4 relating to the grant of a non-statutory stock option on May 3,
2006;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | on May 8, 2006, Robert I. Weisberg, a member of our Board of Directors, filed a late Form 4 relating to the grant of a non-statutory stock option on
May 3, 2006; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | on November 2, 2006, Dennis Haines, our Vice President and General Counsel, filed a late Form 4 relating to the grant of a non-statutory stock option on
October 16, 2006.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Code of Ethics

We have adopted a code of business conduct and ethics that applies to our directors, officers (including our principal executive officer, principal financial officer, principal accounting officer or controller, or
persons performing similar functions) as well as our employees. A copy of our code of business conduct and ethics is available on our website at www.environmentalpower.com under Investor RelationsCorporate Governance. We intend to
post on our website all disclosures that are required by applicable law, the rules of the Securities and Exchange Commission or Amex listing standards concerning any amendment to, or waiver from, our code of business conduct and ethics.

|-------- | ----------------------

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, 2006, 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, along with an additional executive officer. . 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 expect to develop formal criteria and programs to reward executive officers based upon an assessment of corporate, business-unit and individual performance. We expect
to evaluate corporate- and 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.

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 compare our compensation packagesincluding levels, components, and mix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.

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

##### Table of Contents

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.

In June 2004, we undertook a comprehensive
review of our compensation policies. At the request of the Compensation Committee, Effective Pay Practices, an outside compensation consulting firm, was hired to review our compensation practices in light of the industry in which we operate, as well
as its current stage of development. Effective Pay Practices review supported the position that the compensation of our top executives was generally in line with that of persons with similar roles in similarly situated companies. However, the
review also indicated that our employees generally ought to receive further equity incentives in the form of stock options, as well as certain adjustments in their base salaries. As a result certain stock-option grants were made and certain salary
adjustments were implemented.

The Compensation Committee revisited these recommendations in the fall of 2005 in connection with its
consideration of additional equity incentives to employees generally. Given our stage of development and the cash requirements of our business plan, the Compensation Committee did not recommend any increases in the cash compensation of our top
executives in 2005.

We made option grants in 2006 exclusively to new-hires, including the Chief Executive Officer and General Counsel. The
Compensation Committee did not engage any outside advisors to assist with those grants or any other compensation-related programs.

In the
first quarter of 2007, the Compensation Committee and management began to examine what actions could be taken generally to reduce the impact of possible future stock-option exercises, in terms of dilution and in view of the limited trading volume in
our common stock. In this regard, the Compensation Committee, in March 2007, 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. These matters included the possible use, in connection with future grants, of stock appreciation rights and the possible settlement, subject to the advice of tax and legal counsel, of certain
existing stock options, if and when exercised, on a net share basis. The review of these initiatives is ongoing.*

Elements of Executive
Compensation

Compensation for our executives generally consists of the following elements:



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



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



| |  |  | stock-based awards;
| | - |  | -------------------



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



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

We have not had any 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, determines subjectively what it believes to be the appropriate level and mix of the various compensation components. 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
provide

|* | An option holder who settles in-the-money options on a net-share basis would receive shares of our common stock equal to the difference between the market value of the
shares subject to the option and their exercise price, less required withholding for taxes. An in-the-money stock-appreciation right similarly is settled through issuance of shares, or cash, reflecting the extent of the increase in stock price. Both
devices are intended to reduce the dilutive effect to existing stockholders that results from an exercise of an option.

##### Table of Contents

cash compensation in the form of base salary to meet estimated competitive salary norms and, to the extent our cash position permits, expect to reward
superior 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, that are intended to create incentives for the achievement both of
specific objectives and/or long-term strategic goals.

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, Transition, Retirement, Consulting and Severance Agreements. In such cases, base salaries have been determined by arms-length negotiations with these executives, either in connection
with their initial hiring or in connection with the retention of such executives and/or their transition to retirement or other roles with our Company.

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 over the last four years. Going forward, as our company
develops, the Compensation Committee expects to work with our President and Chief Executive Officer to develop appropriate corporate and individual performance goals that can be reasonably achieved with an appropriate level of effort over the course
of the year. We would expect targeted performance criteria to vary for each executive based on areas of responsibility and on the executives leadership. In considering bonuses in the future, the Compensation Committee does not expect to rely
on a formula that assigns a pre-determined value to each of the criteria, but instead expects to evaluate each executive officers contribution in light of all relevant criteria and taking into account our future cash position.

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 2006 we generally made stock-based awards in connection with the hiring of executives, including the Chief Executive Officer and the General Counsel. In the future, we
expect to consider making awards on an annual basis in connection with our annual reviews of executive performance and compensation, as well as in connection with appropriate events, such as the promotion of the executive. The Compensation Committee
expects to take into account the value of stock-based awards or other long-term compensation arrangements previously granted or entered into with the executive in making grants of stock-based awards. The value represented by previous awards,
however, will not necessarily cause the Committee to forego making, or reduce the size of, a future award. We generally grant stock-based awards with installment-vesting (over a period of up to four years) but also consider possible cliff-vesting,
where the grant vests all at once after a specified period, and performance-vesting in appropriate situations.

Because of the direct
relationship between the value of an option and the market price of our common stock, we believe that stock options are an effective method of motivating the executive officers to manage our Company in a manner that is consistent with the interests
of our Company and our stockholders. However, because of the evolution of regulatory, tax and accounting treatment of equity incentive programs, as well as the low trading volume our common stock has historically experienced, and because it is
important to us to retain our executive officers and key employees, it is important that we utilize other forms of equity awards as and when we may deem necessary. We have begun utilizing stock appreciation rights with our employees and in the
future expect to utilize them, stock option settlement on a net-share basis, and/or restricted stock awards. By doing so, we hope to achieve the same motivational and compensatory benefits associated with stock options while issuing fewer shares of
our common stock.

Insurance and Other Employee Benefits. 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.

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, and the severance arrangements entered into with executive officers who departed in 2006, are described in greater detail under
Employment, Transition, Retirement, Consulting and Severance Arrangements, Summary of Potential Payments Upon Termination or Change of Control and Summary of Actual Payments Upon Retirement or
Termination of Employment.

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 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 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.

Management does not play any role in setting non-employee director
compensation. Decisions with respect to non-employee director compensation are made by the Compensation Committee based upon a review data from SEC filings and other sources.

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 currently have any equity ownership
guidelines for our executive officers.

Discussion of Specific Compensation Arrangements Entered into in 2006

In 2006, with the exception of John ONeill, our Chief Financial Officer, compensation for our top executives was determined largely through
negotiations with such executives in connection with the hiring of such executives or their transition to new roles, as described in more detail below. No changes were made with respect to Mr. ONeills compensation in 2006.

In July 2006, we hired Richard E. Kessel to take over Kamlesh R. Tejwanis responsibilities as our President and Chief Executive
Officer. Mr. Kessels base salary was set at $300,000, as compared to Mr. Tejwanis base salary of $225,000, and he was granted options to purchase 400,000 shares of our common stock, as compared to the grant to Mr. Tejwani
of options to purchase 571,429. The terms of Mr. Kessels employment arrangements are set forth in greater detail under the heading Information About Executive and Director CompensationEmployment, Transition, Retirement,
Consulting and Severance Arrangements. While Mr. Kessels employment terms resulted from arms-length negotiations with him, we conducted these negotiations in light of compensation arrangements for chief executives of similarly
situated companies, gained through personal experience and informal inquiry. As a result, we believe that Mr. Kessels salary and equity compensation were set at a level commensurate with his extensive experience, with the responsibility
associated with being the President and Chief Executive Officer of our Company and with the compensation afforded to executives fulfilling similar functions at similarly situated companies. We also believe that Mr. Kessels other
employment terms are also appropriate given his experience and responsibilities as well as the terms of employment of other chief executives of similarly situated companies.

In July 2006, we entered into transition and consulting agreements with Messrs. Tejwani, Cresci and Livingston. At the time that these arrangements were
entered into, our Company was engaged in several critical initiatives, including an effort to raise equity financing, an effort to raise tax-exempt bond financing for our subsidiary, Microgy, and an effort to build out the first of our facilities in
Texas. We believe that it was necessary to retain access to Mr. Tejwanis expertise with respect to the capital markets and his relationships in that field in order to complete our equity financing successfully, which was, in fact,
completed in November 2006. Mr. Cresci had taken the lead on, and was deeply involved in, the tax-exempt bond financing in Texas, which was also successfully completed in November 2006. Similarly, Mr. Livingston had been tasked with the
build out of the Huckabay Ridge facility in Texas, and the conclusion of agreements relating to our other proposed Texas facilities, efforts on which the success of the Texas bond financing would depend. As a result of our need to retain the
services of these individuals past what would have otherwise been their separation or retirement dates, we entered into the Transition Agreement with Mr. Tejwani and the Consulting Agreements with Messrs. Cresci and Livingston described under
the heading Employment, Transition, Consulting, Retirement and Severance Arrangements. In addition, Mr. Cresci continued to lead the Texas bond financing effort past the September 30, 2006 expiration date of his
Consulting Agreement, and to play a significant role in our federal legislative initiatives over the remainder of 2006. For these efforts, we entered into the additional letter agreement with Mr. Cresci which is also described under the heading
Employment, Transition, Consulting, Retirement and Severance Arrangements.

##### Table of Contents

With respect to Mr. Tejwanis Transition Agreement, his rate of compensation was a continuation
of his then current base salary, and we believe that the separation benefits provided to him were consistent with those typically afforded outgoing chief executives of similarly situated companies, particularly those departing on good terms. With
respect to Messrs. Cresci and Livingston, their rates of compensation were negotiated with them. As both individuals had served well beyond their originally anticipated retirement dates of December 31, 2005, and had agreed to significant
reductions in their base salaries in 2004, it was necessary to increase their rates of compensation over that which they had been receiving prior to their June 30, 2006 retirement dates. Messrs. Cresci and Livingston continued to be treated as
employees, but not executive officers, during the term of their respective agreements.

In October 2006, we extended an offer letter to
Dennis Haines in connection with his hiring as our Vice President and General Counsel. We believe that the terms of Mr. Haines employment are comparable to those of executives in like positions with similarly situated companies and
commensurate with his responsibilities and extensive level of corporate, commercial and administrative experience.

Executive Compensation

Summary Compensation

The following table sets forth information for the fiscal year ended December 31, 2006
regarding the compensation of our Chairman, our President and Chief Executive Officer, our Chief Financial Officer, our former President and Chief Executive Officer and two additional former executive officers who would have been among our most
highly compensated executive officers if they had been serving as executive officers on December 31, 2006. We refer to these individuals as our named executive officers. In addition, we have elected to provide information regarding the
compensation of Dennis Haines, our Vice President and General Counsel, even though he served for only a portion of the fourth quarter of 2006 and therefore earned total compensation less than $100,000. We refer to Mr. Haines as the additional
executive officer.

following principal terms:



| |  |  | An annual base salary of $225,000, subject to discretionary salary increases and annual discretionary bonuses determined by our Board of Directors.
Mr. Tejwanis salary was not increased during the term of his employment, nor were any bonuses paid to him.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Full health care coverage, paid vacation and the use of a company leased vehicle
| | - |  | --------------------------------------------------------------------------------



| |  |  | The grant of a non-statutory stock option, which as made in July 2003 and subsequently amended in March 2004. Mr. Tejwanis amended non-statutory stock
option agreement provides for options to acquire 571,429 shares of our common stock that are exercisable in two tranches.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On April 11, 2006, we entered into a letter agreement with Mr. Tejwani relating to his
employment agreement, providing that any severance or other benefits to which Mr. Tejwani may be entitled following termination of his employment will be payable beginning on the first day of the seventh month following separation of service,
with the aggregate amount of what would otherwise be the first seven months of installments to be paid at the beginning of the seventh month following separation from service. The purpose of this letter agreement was to bring such severance
arrangements into compliance with Section 409A of the Internal Revenue Code of 1986, as amended.

On July 17, 2006, following the
expiration of Mr. Tejwanis employment agreement, we entered into a transition agreement with Mr. Tejwani. The transition agreement provided for the following principal terms:



| |  |  | Mr. Tejwani resigned from his positions as our President and Chief Executive Officer, effective July 17, 2006.
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | Mr. Tejwani retained his position as Vice Chairman, in which capacity he agreed to provide such services, and undertake such projects, as our Board of
Directors or Chief Executive Officer may direct, on a substantially full-time basis, until at least June 30, 2007, or such earlier date as we may determine.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mr. Tejwani would continue to receive his current salary for the entire transition period.
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Mr. Tejwanis separation from employment would be deemed to be a termination without cause for purposes of his non-statutory stock option agreement, such
that such option would remain exercisable throughout its original term.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Following the transition period, unless he is terminated for cause, as defined in the transition agreement, Mr. Tejwani would be entitled to separation
payments and benefits, as follows:
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Separation payments equal to one years base salary ($225,000), beginning with a lump sum payment equal to six months base salary on the date which is
six months after the end of his employment with us, with the balance paid in equal monthly installments thereafter.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During the 12-month period following the later of (i) December 31, 2006 or (ii) the end of his employment with us, we will continue to provide
Mr. Tejwani with his current medical, dental and life insurance benefits.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In addition, if Mr. Tejwanis services are terminated prior to December 31, 2006, he would be entitled to be paid his current salary and benefits
through such date.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During the transition period and, if the transition period is terminated without cause, until June 30, 2007, we will continue to provide Mr. Tejwani with
his current car lease and cell phone reimbursement, as well as office space and office equipment in New York City comparable to his current arrangements.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Mr. Tejwanis transition agreement is in lieu of and supersedes Mr. Tejwanis employment agreement, except that the proprietary
information, assignment of inventions, non-competition and non-solicitation provisions of his employment agreement survive. Mr. Tejwani and Environmental Power mutually agreed that Mr. Tejwanis employment under the transition

##### Table of Contents

Board of Directors, referred to as the executives, regarding certain compensation, transition and retirement arrangements for the executives. The letter
agreements, which were effective as of July 13, 2005, provided for the following principal terms:



| |  |  | Each executive agreed to continue to serve in his then-current position as an employee of our company until December 31, 2005, provided, however, that in the
event that all of the options described below were vested as of such date, our Board of Directors may elect to extend such period of employment until no later than June 30, 2006, unless a later date is mutually agreed upon between us and the
executive, with the date ultimately determined or agreed upon being referred to as the retirement date.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During the period ending on the retirement date, referred to as the transition period, we agreed to continue to pay each executive his then-current salary ($225,000
per year), and to provide the executive with his then-current benefits. In addition, provided the executive continued to perform his duties for the entire transition period, then, for the 12-month period following the retirement date, we agreed to
continue to pay the executive an amount equal to his then-current salary, plus such benefits as were then enjoyed by such executive. Thereafter, we agreed to provide each executive with family medical insurance until the executive is eligible for
Medicare.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Each executive agreed to mentor the president of Microgy and such other officers or employees of Environmental Power or Microgy as the Board may reasonably request,
and to provide support for the business development efforts of Environmental Power and its subsidiaries consistent with their historical positions, responsibilities and activities.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We granted a non-statutory stock option to each executive to purchase up to 200,000 shares of our common stock at an exercise price equal to the fair market value
of our common stock on the date of grant. The vesting of the options was based on the achievement of certain corporate goals related to the business development efforts of Microgy, to which the executives were expected to make a significant
contribution during the transition period. The options vested as follows:
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 75% of the shares subject to each option would vest if, on or before October 31, 2005, management presented to our Board of Directors one or more agreements
involving South-Tex Treaters, Inc. or a comparable provider of gas scrubbing equipment and services relating to one or more projects in the Southwestern United States providing for the development or construction of the equivalent of an aggregate of
10 digesters having a capacity of 700,000 gallons each, and the board authorized further investment in such project or projects and, therefore, determined that the shares should vest.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 25% of the shares subject to each option would vest if, on or before December 31, 2006, in addition to the projects referred to above, management presented to
our Board of Directors one or more agreements and/or a report regarding completed development steps pertaining to a second project or group of projects of an aggregate size comparable to the project or projects described above, and the board
authorized further investment in such project or projects and, therefore, determined that the shares should vest.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the event that, following the presentation of any project or projects to our Board of Directors as described above, if at any time during the 12-month period
following such presentation, we should later determine to invest any corporate resources (including the time of corporate personnel) in pursuit of such project or projects, then such investment would be deemed to have been approved by the board
within the time periods set forth above and the option shall be deemed to be vested as to the percentage of shares related thereto.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the event that the executive were terminated by our Board of Directors without cause prior to the retirement date, the executive would be entitled to severance
equal to 12 months of his current base salary, paid in accordance with our usual payroll practices, together with all other payments or benefits otherwise contemplated by the letter agreement. In addition, all options would vest in full,
except to the extent that such termination occurs after the date for satisfaction of the applicable vesting criteria and such vesting criteria have not been satisfied on or prior to such date.

##### Table of Contents

On December 30, 2005, we entered into an amendment to the July 13, 2005 letter agreement with
Mr. Cresci. The amendment provides for the following principal terms:



| |  |  | Mr. Crescis retirement date as set forth in the July 13, 2005 letter agreement was extended to June 30, 2006. During the remainder of the
transition period ending on such date, Mr. Cresci was to provide such support for the business development efforts of Environmental Power and Microgy as we may reasonably request, consistent with the relocation of Mr. Crescis
principal residence to Florida and a part-time schedule.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mr. Crescis salary during the period beginning on January 1, 2006 and continuing through the retirement date was to be 50% of his current salary,
and his benefits were to remain the same as those he then enjoyed.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, this amendment made clear that any
retirement or severance payments and benefits to which Mr. Cresci is entitled will be paid in such manner and at such times as we and Mr. Cresci agree will be compliant with Section 409A of the Code. The other terms of
Mr. Crescis letter agreement were unaffected. On April 11, 2006, we entered into a further amendment to Mr. Crescis letter agreement providing for the resumption by Mr. Cresci of a full-time schedule for the remainder
of the transition period, as defined in his original letter agreement, which ended on June 30, 2006, and the restoration of Mr. Crescis full salary as of the end of 2005, effective April 1, 2006 for the remainder of the
transition period.

Also on December 30, 2005, we entered into a further letter agreement with Donald A. Livingston, relating to his
July 13, 2005 letter agreement, confirming that Mr. Livingstons retirement date had been extended to June 30, 2006 and that Mr. Livingstons principal responsibilities would be to lead a team devoted to Microgys
project development efforts. In addition, this letter agreement made clear that any retirement or severance payments and benefits to which Mr. Livingston is entitled will be paid in such manner and at such times as we and Mr. Livingston
agree will be compliant with Section 409A of the Code. The other terms of Mr. Livingstons original letter agreement were unaffected.

In connection with the extension of Mr. Livingstons retirement date pursuant to the December 30, 2005 letter agreement, on December 30, 2005, the Compensation Committee of our Board of Directors
authorized the grant to Mr. Livingston of a bonus unit award under our 2005 Equity Incentive Plan. The bonus unit award provided for the following principal terms:



| |  |  | An award of 7,000 bonus units, each of which is a unit of value, valued by reference to the increase, if any in the fair market value of a share of our common stock
over the initial value. The initial value of each bonus unit was $7.00 per unit.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Each bonus unit represented the right, subject to the terms of our 2005 Equity Incentive Plan and the bonus unit award agreement, to receive a payment, in cash or
in shares of common stock, at the discretion of the Compensation Committee, on the bonus date, equal to the positive difference, if any, between the initial value and the fair market value of a share of the common stock on June 30, 2006, which
is the bonus date for purposes of the bonus unit award. Bonus units were used solely as units of measurement and were not shares of our common stock.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The bonus units were to vest, if at all, only if our Board of Directors or the Compensation Committee, as the case may be, determined, in its sole discretion, that
Microgys pipeline gas development team, of which Mr. Livingston is a member, has made a significant contribution to the advancement of the business of Environmental Power and Microgy.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mr. Livingston was required to continuously remain an employee of, or consultant or advisor to, Environmental Power or Microgy and a member of the pipeline gas
development team, from the grant date through and including the bonus date, or the bonus units and the right to any payment in respect thereof would be immediately forfeited.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

The bonus unit award to Mr. Livingston was one of several such awards made in equal amounts to
Mr. Livingston and the other members of Microgys pipeline gas development team, which is comprised of seven Microgy employees and consultants tasked with furthering the development of projects related to Microgys pipeline gas
business. As the closing price of our common stock was $6.55 on June 30, 2006, less than the $7.00 initial value, none of the bonus unit awards had any value, and, therefore, no determinations were made as to vesting by our Board of Directors
or the Compensation Committee, no payments were made to Mr. Livingston or any other recipient in connection with such awards, and such awards expired by their terms.

Consulting Agreements with Joseph E. Cresci and Donald A. Livingston

On July 17, 2006, we
entered into consulting agreements with each of Messrs. Cresci and Livingston in connection with their transition to non-executive roles with Environmental Power and the expiration of their transition periods under their letter agreements described
above. The consulting agreements, which were retroactive to July 1, 2006, provided for the following principal terms:



| |  |  | Each of Messrs. Cresci and Livingston agreed to provide such services, and undertake such projects, as our Board of Directors or Chief Executive Officer directed,
on a substantially full-time basis, during the period ending on December 31, 2006, in the case of Mr. Livingston, and September 30, 2006, in the case of Mr. Cresci.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Each of Messrs. Cresci and Livingston were compensated at the rate of $41,666.66 per month during their respective consulting period.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The consulting agreements contained customary proprietary information and assignment of inventions provisions.
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | Messrs. Cresci and Livingston each agreed that they will not compete with Environmental Power or its subsidiaries, or solicit their employees, during the consulting
period and for a period of five (5) years thereafter.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The earlier letter agreements between us and each of Messrs.
Cresci and Livingston, dated July 13, 2005, as amended to date, were unaffected by the terms of the consulting agreements and remain in full force and effect.

Consulting Letter Agreement with Joseph E. Cresci

On December 19, 2006, we entered into a consulting letter agreement
with Mr. Cresci, pursuant to which we agreed to compensate him for consulting services rendered since September 30, 2006, the date on which his consulting agreement described above expired, as well as to compensate him for services
expected to be rendered by him through December 31, 2006. In consideration of his services in connection with our tax-exempt bond financing in Texas, as well as his continued services in connection with certain legislative initiatives through
the end of this year, we agreed to pay Mr. Cresci the following amounts in a lump sum on January 2, 2007 following completion of such services:



| |  |  | $41,666.66 in respect of services rendered for the month of October 2006;
| | - |  | -------------------------------------------------------------------------



| |  |  | $30,000.00 in respect of services rendered for the month of November 2006; and
| | - |  | ------------------------------------------------------------------------------



| |  |  | $25,000.00 in respect of services rendered for the month of December 2006.
| | - |  | --------------------------------------------------------------------------

Current Status of Messrs. Cresci and Livingston and Retirement Arrangements

Messrs. Cresci and
Livingston ceased to be employees of Environmental Power on September 30, 2006 and December 31, 2006, respectively. Mr. Cresci continues to serve on our Board of Directors as non-executive Chairman. Mr. Livingston resigned from
all positions with Environmental Power and its subsidiaries on January 8, 2007 in connection with his retirement. We anticipate that retirement payments to Messrs. Cresci and Livingston under their original letter agreements will commence in
July 2007.

On June 12, 2006, Environmental Power and Microgy entered into a release and severance agreement with Randall L. Hull, the former President of

| |  |  | In exchange for the payments due to Mr. Hull pursuant to such agreement, Mr. Hull released Environmental Power, Microgy and their affiliates from any and
all claims that he may have had in connection with his employment with Microgy and the termination thereof; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | All payments paid or due to be paid to Mr. Hull pursuant to such agreement were contingent upon Mr. Hulls observance and performance of his
obligations pursuant to the such agreement and that certain employee proprietary information and inventions agreement executed by Mr. Hull in connection with the commencement of his employment with Microgy.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We fulfilled our obligations under the release and severance agreement with Mr. Hull by payment in September 2006 of the remaining severance due to
Mr. Hull thereunder.

Effective January 1, 1998 we established the EPC Retirement Plan, a non-contributory defined
benefit pension plan covering all of our employees who were at least 21 years of age and who had completed at least one year of service. Under the EPC Retirement Plan, the benefits payable to each employee at normal retirement age 62 were based on
years of service and compensation during the three consecutive years of the latest 10 years immediately preceding retirement that would yield the highest monthly benefit payment. Employees who had at least 20 years of service at the time of their
retirement would receive the maximum retirement benefit. Our general funding policy was to contribute annually to the EPC Retirement Plan the maximum amount that could be deducted for Federal income tax purposes.

On January 1, 2003 we amended the EPC Retirement Plan. Certain employees after 2002 had an accrued benefit plus the benefit earned under the new
formula applied to years of credited service earned after 2002. The normal retirement age was increased to 65. The amended plan had a two year waiting period before employees entered the plan. Employees who joined the plan after two years were fully
vested at that time. The benefit was accrued at 1.5% of the average monthly compensation for each year of credited service, without a cap.

On September 30, 2005, we terminated the EPC Retirement Plan. Although benefit accruals after that date were removed from the plan, all active participants received benefit accruals for all of 2005 since service is based on 1,000 hours
for a full year. The payments made during 2006 as reflected in the table above relate to the distribution of all accumulated benefits under the EPC Retirement Plan to the named participants.

Payments Upon Termination or Change of Control

We have entered into employment agreements with each of the named executive officers and the additional executive officer. These employment agreements provide for payments and benefits to the executive officer upon termination of employment
or a change of control of Environmental Power under specified circumstances. For information regarding the specific circumstances that would trigger payments and the provision of benefits, the manner in which payments and benefits would be provided
and conditions applicable to the receipt of payments and benefits, see Employment, Transition, Retirement, Consulting and Severance Arrangements. Furthermore, we entered into letter agreements in 2005 with each of Messrs. Cresci
and Livingston relating to their retirement from active employment with Environmental Power. For information regarding these letter agreements, see Employment, Transition, Retirement, Consulting and Severance Arrangements. In addition,
we entered into a

separation agreement with Mr. Hull in connection with his termination from employment that provided for actual payments and benefits to Mr. Hull.
For more information regarding this separation agreement, see Employment, Transition, Retirement, Consulting and Severance Arrangements.

The following tables set forth information regarding potential payments and benefits that each named executive officer and the additional executive officer who was serving as an executive officer on December 31,
2006 would receive upon termination of employment or a change of control of Environmental Power under specified circumstances, assuming that the triggering event in question occurred on December 29, 2006, the last business day of the fiscal
year.

|(1) | The amounts in the Option Awards column reflect the dollar amounts recognized as compensation expense for financial statement reporting purposes for stock options for
the fiscal year ended December 31, 2006 in accordance with SFAS 123(R), 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. The assumptions we used to calculate these amounts are discussed in Note I to our consolidated
financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2006.

Effective June 1, 2005, we began paying each of our non-employee directors a monthly stipend of
$1,000, and a per meeting fee of $1,500. In addition, the chairman of the Audit Committee receives $4,000 for each meeting of the Audit Committee attended. Furthermore, under our 2006 Director Option Plan, each non-employee director as of the close
of business on the day on which our annual meeting of stockholders is held each year automatically receives a fully vested, non-statutory stock option to purchase 15,000 shares of our common stock at an exercise price equal to the fair market value
of our common stock on such date.

Compensation Committee Interlocks and Insider Participation

The members of the Compensation Committee during the fiscal year ended December 31, 2006 were Messrs. Hatamiya, Schumacher and Weisberg. No member of
the Compensation Committee was at any time during the fiscal year ended December 31, 2006, or formerly, an officer or employee of Environmental Power or any subsidiary of Environmental Power, nor has any member of the Compensation Committee had
any relationship with Environmental Power during the fiscal year ended December 31, 2006 requiring disclosure under Item 404 of Regulation S-K.

None of our executive officers has served as a director or member of the Compensation Committee (or other committee serving an equivalent function) of any other entity, one of whose executive officers served as a
director or member of the Compensation Committee of Environmental Power.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with
management. Based on this review and discussion, the Compensation Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K/A for the year ended December 31,
2006 and the proxy statement of Environmental Power for its 2007 Annual Meeting of Stockholders.

|(3) | This entity has an address of 4 Embarcadero Center, Suite 2050, San Francisco, CA 94111. The number of shares of series A preferred stock beneficially owned is comprised of 52,823
shares of series A preferred stock held Fort Mason Master, L.P. and 3,425 shares of series A preferred stock held by Fort Mason Partners, L.P. These stockholders also hold warrants to purchase 264,115 and 17,125 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. Fort Mason Capital, LLC is the general partner of each of these stockholders and, in such capacity, may be deemed to beneficially
own the shares held by these stockholders insofar as it exercises sole voting and investment authority with respect to such shares. Fort Mason Capital, LLC disclaims beneficial ownership of the shares beneficially owned by these stockholders, except
to the extent of its pecuniary interest therein, if any.

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

Employment, Transition, Retirement, Consulting and Severance Agreements

We have entered into employment, transition, retirement, consulting and severance 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, 2006 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.

---

##### Table of Contents

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.

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.

We did not have a written policy regarding the review and approval of related person transactions during
2006. Nevertheless, with respect to such transactions in 2006, it was our policy that the Audit Committee or another committee of independent directors consider the nature of and business reason for such transactions, how



31

##### Table of Contents

the terms of such transactions compared to those which might be obtained from unaffiliated third parties and whether such transactions were otherwise fair to
and in the best interests of, or not contrary to, our best interests. In addition, all related person transactions required prior approval, or later ratification, by the Audit Committee or a committee of independent directors. There were no related
person transactions in 2006 with respect to which these policies and procedures were not followed.

Director Independence

Under applicable American Stock Exchange rules, 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. Cooper, Hatamiya, Schumacher or Weisberg 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 Section 121A of the Amex Company Guide.

Pre-Approval Policy and Procedures

The Audit Committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our
