PROXY STATEMENT

This proxy statement contains information related to the Annual Meeting of Stockholders to be held on May 25, 2017 at 9:00 a.m. local time, at Corbus Pharmaceuticals Holdings, Inc. (the “Company”) located at 100 River Ridge Drive, Suite 103, Norwood, MA 02062, or at such other time and place to which the Annual Meeting may be adjourned or postponed. The enclosed proxy is solicited by the Board of Directors of Corbus Pharmaceuticals Holdings, Inc. (the “Board”). The proxy materials relating to the Annual Meeting are being mailed to stockholders entitled to vote at the meeting on or about April 10, 2017.

ABOUT THE MEETING

Why are we calling this Annual Meeting?

We are calling the Annual Meeting to seek the approval of our stockholders:

What are the Board’s recommendations?

Our Board believes that the election of the director nominees identified herein, the amendment and restatement of our certificate of incorporation, as amended, as described herein, and the appointment of EisnerAmper LLP as our independent registered public accounting firm for the year ending December 31, 2017 are advisable and in the best interests of the Company and its stockholders and recommends that you vote FOR these proposals.

Why did I receive a notice in the mail regarding the Internet availability of the proxy materials instead of a paper copy of the proxy materials?

In accordance with rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to furnish to our stockholders this Proxy Statement and our Fiscal 2016 Annual Report by providing access to these documents on the Internet rather than mailing printed copies. Accordingly, a Notice of Internet Availability of Proxy Materials (the “Notice”) is being mailed to our stockholders of record and beneficial owners which will direct stockholders to a website where they can access our proxy materials and view instructions on how to vote online or by telephone. If you would prefer to receive a paper copy of our proxy materials, please follow the instructions included in the Notice.

Who is entitled to vote at the meeting?

Only stockholders of record at the close of business on the record date, April 3, 2017, are entitled to receive notice of the Annual Meeting and to vote the shares of common stock that they held on that date at the meeting, or any postponement or adjournment of the meeting. Holders of our common stock are entitled to one vote per share on each matter to be voted upon.

As of the record date, we had 50,143,742 outstanding shares of common stock.

Who can attend the meeting?

All stockholders as of the record date, or their duly appointed proxies, may attend the Annual Meeting. Please note that if you hold your shares in “street name” (that is, through a broker or other nominee), you will need to bring a copy of your proxy card delivered to you by your broker or a legal proxy given to you by your broker and check in at the registration desk at the meeting.

What constitutes a quorum?

The presence at the Annual Meeting, in person or by proxy, of the holders of a majority of our common stock outstanding on the record date will constitute a quorum for our meeting. Signed proxies received but not voted and broker non-votes will be included in the calculation of the number of shares considered to be present at the meeting.

How do I vote?

You can vote on matters that come before the Annual Meeting via the Internet by following the instructions in the Notice or by submitting your proxy card by mail. If you would prefer to vote by mail, please follow the instructions included in the Notice to receive a paper copy of our proxy materials.

If you are a stockholder of record, to submit your proxy by mail or vote via the Internet, follow the instructions on the proxy card or Notice. If you hold your shares in street name, you may vote via the Internet as instructed by your broker, bank or other nominee.

Your shares will be voted as you indicate on your proxy card. If you vote your proxy but you do not indicate your voting preferences, and with respect to any other matter that properly comes before the meeting, the individuals named on the proxy card will vote your shares FOR the matters submitted at the meeting, or if no recommendation is given, in their own discretion.

If you attend the Annual Meeting and prefer to vote in person, you may do so even if you have already voted your shares by proxy.

What if I vote and then change my mind?

You may revoke your proxy at any time before it is exercised by:

For purposes of submitting your vote online, you may change your vote until 7:00 p.m. on May 24, 2017. At this this deadline, the last vote submitted will be the vote that is counted.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

Many of our stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

Stockholder of Record

If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust, you are considered, with respect to those shares, the stockholder of record. As the stockholder of record, you have the right to grant your voting proxy directly to us or to vote in person at the Annual Meeting.

Beneficial Owner

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in street name, and these proxy materials are being forwarded to you by your broker, bank or nominee which is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker as to how to vote and are also invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting unless you obtain a signed proxy from the record holder giving you the right to vote the shares. If you do not vote your shares or otherwise provide the stockholder of record with voting instructions, your shares may constitute broker non-votes. The effect of broker non-votes is more specifically described in “What vote is required to approve each proposal?” below.

What vote is required to approve each proposal?

The holders of a majority of our common stock outstanding on the record date must be present, in person or by proxy, at the Annual Meeting in order to have the required quorum for the transaction of business. Pursuant to Delaware corporate law, abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present.

Assuming that a quorum is present, the following votes will be required:

Holders of the common stock will not have any dissenters’ rights of appraisal in connection with any of the matters to be voted on at the meeting.

What are “broker non-votes”?

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, your shares are held by your broker, bank or other agent as your nominee, or in “street name,” and you will need to obtain a proxy form from the organization that holds your shares and follow the instructions included on that form regarding how to instruct the organization to vote your shares. If you do not give instructions to your broker, bank or other agent, it can vote your shares with respect to “discretionary” items but not with respect to “non-discretionary” items. Discretionary items are proposals considered routine under the rules of various national securities exchanges, and, in the absence of your voting instructions, your broker, bank or other agent may vote your shares held in street name on such proposals. Non-discretionary items are proposals considered non-routine under the rules of various national securities exchanges, and, in the absence of your voting instructions, your broker, bank or other agent may not vote your shares held in street name on such proposals and the shares will be treated as broker non-votes. Proposals 1, 2, 3 and 4 are generally considered non-routine matters under the applicable rules. If you do not give your broker specific instructions, the broker may not vote your shares on Proposals 1, 2, 3 and 4 and therefore there may be broker non-votes on Proposal 1, 2, 3 and 4. Proposal 5 involves a matter we believe to be routine and thus if you do not give instructions to your broker, the broker may vote your shares in its discretion on Proposal 5 and therefore no broker non-votes are expected to exist in connection with Proposal 5.

How are we soliciting this proxy?

We are soliciting this proxy on behalf of our Board and will pay all expenses associated therewith. Some of our officers, directors and other employees also may, but without compensation other than their regular compensation, solicit proxies by further mailing or personal conversations, or by telephone, facsimile or other electronic means.

In addition, we have engaged Alliance Advisors, LLC to assist us in soliciting proxies from banks, brokers and nominees. The fees that will be paid to Alliance Advisors, LLC are anticipated to be approximately $7,000, and we will reimburse any out-of-pocket expenses.

We will also, upon request, reimburse brokers and other persons holding stock in their names, or in the names of nominees, for their reasonable out-of-pocket expenses for forwarding proxy materials to the beneficial owners of the capital stock and to obtain proxies.

PROPOSAL 1: TO ELECT FIVE DIRECTORS TO SERVE UNTIL THE NEXT ANNUAL MEETING AND UNTIL THEIR SUCCESSORS HAVE BEEN DULY ELECTED AND QUALIFIED

Our Board is currently composed of five directors. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that director for which the vacancy was created and until the director’s successor is duly elected and qualified.

Each of the nominees listed below is currently one of our directors. If elected at the Annual Meeting, each of these nominees would serve until the next annual meeting and until his or her successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. Abstentions and broker non-votes will not be treated as a vote for or against any particular director nominee and will not affect the outcome of the election. Stockholders may not vote, or submit a proxy, for a greater number of nominees than the five nominees named below. The director nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the five director nominees named below. If any director nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by our Board. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

Nominees for Election Until the Next Annual Meeting

The following table sets forth the name, age, position and tenure of each of our directors who are up for re-election at the 2017 Annual Meeting:

The following includes a brief biography of each of the nominees standing for election to the Board of Directors at the Annual Meeting, based on information furnished to us by each director nominee, with each biography including information regarding the experiences, qualifications, attributes or skills that caused the Nominating and Corporate Governance Committee and the Board of Directors to determine that the applicable nominee should serve as a member of our Board of Directors.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE ELECTION OF THE DIRECTOR NOMINEES.

CORPORATE GOVERNANCE

Board of Director Composition

Our Board currently consists of five members. Our directors hold office until their successors have been elected and qualified or until the earlier of their resignation or removal.

We have no formal policy regarding board diversity. Our priority in selection of board members is identification of members who will further the interests of our stockholders through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, knowledge of our business and understanding of the competitive landscape.

Board of Director Meetings

Our Board met seven times in 2016. Each of the directors attended at least 75% of the aggregate of (i) the total number of meetings of our Board (held during the period for which such directors served on the Board) and (ii) the total number of meetings of all committees of our Board on which the director served (during the periods for which the director served on such committee or committees). All five (5) of our directors attended our 2016 Annual Meeting of Stockholders. We do not have a formal policy requiring members of the Board to attend our annual meetings.

Director Independence

Our common stock is listed on The NASDAQ Stock Market. Under the rules of The NASDAQ Stock Market, independent directors must comprise a majority of our Board. In addition, the rules of The NASDAQ Stock Market require that all the members of such committees be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Compensation committee members must also satisfy the independence criteria established by The NASDAQ Stock Market in accordance with Rule 10C-1 under the Exchange Act. Under the rules of The NASDAQ Stock Market, a director will only qualify as an “independent director” if, among other qualifications, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our Board undertook a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that Mr. Holmer, Dr. Gupta and Mr. Catlin do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the Rules of the NASDAQ Stock Market and the SEC.

In making this determination, our Board considered the relationships that each non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining their independence. We intend to comply with the other independence requirements for committees within the time periods specified above.

Board Committees

Our Board has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. Our Board may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of these committees operate under a charter that has been approved by our Board.

Audit Committee. Our Audit Committee consists of Mr. Holmer, Dr. Gupta and Mr. Catlin, and Mr. Catlin is the Chairman of the Audit Committee. Our Audit Committee met five times in 2016. Our Board has determined that the three directors currently serving on our Audit Committee are independent within the meaning of The NASDAQ Marketplace Rules and Rule 10A-3 under the Exchange Act. In addition, our Board has determined that Mr. Catlin qualifies as an audit committee financial expert within the meaning of SEC regulations and The NASDAQ Marketplace Rules.

The Audit Committee oversees and monitors our financial reporting process and internal control system, reviews and evaluates the audit performed by our registered independent public accountants and reports to our Board any substantive issues found during the audit. The Audit Committee will be directly responsible for the appointment, compensation and oversight of the work of our registered independent public accountants. The Audit Committee reviews and approves all transactions with affiliated parties. Our Board has adopted a written charter for the Audit Committee. A copy of the charter is posted under the “Investors” tab under “Governance” in our website, which is located at www.corbuspharma.com.

Compensation Committee. Our Compensation Committee consists of Mr. Holmer, Dr. Gupta and Mr. Catlin, and Mr. Holmer is the Chairman of the Compensation Committee. Our Compensation Committee met eight times in 2016. Our Board has determined that the three directors currently serving on our Compensation Committee are independent under the listing standards, are “non-employee directors” as defined in Rule 16b-3 promulgated under the Exchange Act and are “outside directors” as that term is defined in Section 162(m) of the Internal Revenue Code of 1986, as amended.

The Compensation Committee provides advice and makes recommendations to our Board in the areas of employee salaries, benefit programs and director compensation. The Compensation Committee also reviews and approves corporate goals and objectives relevant to the compensation of our President, Chief Executive Officer, and other officers and makes recommendations in that regard to our Board as a whole.

In 2016, the Compensation Committee directly engaged independent compensation consultants, Willis Towers Watson, and subsequently Radford, a part of Aon Hewitt, a business unit of Aon plc, to provide advice and recommendations on the structure, amount and form of executive and director compensation and the competitiveness thereof. At the request of the Compensation Committee, the compensation consultants provided, among other things, comparative data from selected peer companies. The compensation consultants report directly to the Compensation Committee. The Compensation Committee’s decision to hire either of the compensation consultants was not made or recommended by Company management. Neither compensation consultant has performed any work for the Company in 2016 except with respect to the work that it has done directly for the Compensation Committee.

Our Board has adopted a written charter for the Compensation Committee. A copy of the charter is posted under the “Investors” tab under “Governance” in our website, which is located at www.corbuspharma.com.

Nominating and Corporate Governance Committee. Our Nominating and Corporate Governance Committee consists of Mr. Holmer, Dr. Gupta and Mr. Catlin, and Dr. Gupta is the Chairman of the Nominating and Corporate Governance Committee. Our Nominating and Corporate Governance Committee met one time in 2016. The Nominating and Corporate Governance Committee nominates individuals to be elected to the full board by our stockholders. The Nominating and Corporate Governance Committee considers recommendations from stockholders if submitted in a timely manner in accordance with the procedures set forth in our bylaws and will apply the same criteria to all persons being considered. All members of the Nominating and Corporate Governance Committee are independent directors as defined under the NASDAQ listing standards. Our Board has adopted a written charter for the Nominating and Corporate Governance Committee. A copy of the charter is posted under the “Investors” tab under “Governance” in our website, which is located at www.corbuspharma.com.

Stockholder nominations for directorships

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting their names and background to the Secretary of the Company at the address set forth below under “Stockholder Communications” in accordance with the provisions set forth in our bylaws. All such recommendations will be forwarded to the Nominating and Corporate Governance Committee, which will review and only consider such recommendations if appropriate biographical and other information is provided, including, but not limited to, the items listed below, on a timely basis. All security holder recommendations for director candidates must be received by the Company in the timeframe(s) set forth under the heading “Stockholder Proposals” below.

Assuming that appropriate information is provided for candidates recommended by stockholders, the Nominating and Corporate Governance Committee will evaluate those candidates by following substantially the same process, and applying substantially the same criteria, as for candidates submitted by members of the Board or other persons, as described above and as set forth in its written charter.

Board Leadership Structure and Role in Risk Oversight

The positions of our chairman of the Board and chief executive officer are separated. Separating these positions allows our chief executive officer to focus on our day-to-day business, while allowing the chairman of the Board to lead our Board in its fundamental role of providing advice to and independent oversight of management. Our Board recognizes the time, effort and energy that the chief executive officer must devote to his position in the current business environment, as well as the commitment required to serve as our chairman, particularly as our Board’s oversight responsibilities continue to grow. Our Board also believes that this structure ensures a greater role for the independent directors in the oversight of our Company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our Board. This leadership structure also is preferred by a significant number of our stockholders. Our Board believes its administration of its risk oversight function has not affected its leadership structure.

Although our bylaws do not require our chairman and chief executive officer positions to be separate, our Board believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including those described under the section entitled “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and other reports filed with the SEC. Our Board is actively involved in oversight of risks that could affect us. This oversight is conducted primarily by our full Board, which has responsibility for general oversight of risks.

Our Board will satisfy this responsibility through full reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within our Company. Our Board believes that full and open communication between management and our Board is essential for effective risk management and oversight.

Stockholder Communications

Our Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Absent unusual circumstances or as contemplated by committee charters, and subject to advice from legal counsel, the Secretary of the Company is primarily responsible for monitoring communications from stockholders and for providing copies or summaries of such communications to the Board as he considers appropriate.

Communications from stockholders will be forwarded to all directors if they relate to important substantive matters or if they include suggestions or comments that the Secretary considers to be important for the Board to know. Communication relating to corporate governance and corporate strategy are more likely to be forwarded to the Board than communications regarding personal grievances, ordinary business matters, and matters as to which the Company tends to receive repetitive or duplicative communications.

Stockholders who wish to send communications to the Board should address such communications to: The Board of Directors, Corbus Pharmaceuticals Holdings, Inc., 100 River Ridge Drive, Suite 103, Norwood, MA 02062, Attention: Secretary.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our employees, officers and directors. A copy of the code is posted under the “Investors” tab under “Governance” in our website, which is located at www.corbuspharma.com. We intend to disclose future amendments to certain provisions of our code of business conduct and ethics, or waivers of such provisions applicable to any principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and our directors, on our website identified above or in a Current Report on Form 8-K.

Limitation of Directors Liability and Indemnification

The Delaware General Corporation Law (the “DGCL”) authorizes corporations to limit or eliminate, subject to certain conditions, the personal liability of directors to corporations and their stockholders for monetary damages for breach of their fiduciary duties. Our certificate of incorporation limits the liability of our directors to the fullest extent permitted by Delaware law. In addition, we have entered into indemnification agreements with certain of our directors and officers whereby we have agreed to indemnify those directors and officers to the fullest extent permitted by law, including indemnification against expenses and liabilities incurred in legal proceedings to which the director or officer was, or is threatened to be made, a party by reason of the fact that such director or officer is or was a director, officer, employee or agent of the Company, provided that such director or officer acted in good faith and in a manner that the director or officer reasonably believed to be in, or not opposed to, the best interests of the Company.

We have director and officer liability insurance to cover liabilities our directors and officers may incur in connection with their services to us, including matters arising under the Securities Act. Our certificate of incorporation and bylaws also provide that we will indemnify our directors and officers who, by reason of the fact that he or she is one of our officers or directors, is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative related to their board role with us.

There is no pending litigation or proceeding involving any of our directors, officers, employees or agents in which indemnification will be required or permitted. We are not aware of any threatened litigation or proceeding that may result in a claim for such indemnification.

The following table sets forth information concerning the compensation paid to certain of our non-employee directors during 2016.

Non-Employee Director Compensation Policy

Our Board has approved a director compensation policy for our non-employee directors. Other than reimbursement for reasonable expenses incurred in connection with attending Board and committee meetings, this policy provides for the following cash compensation effective January 2016:

General

On March 26, 2014, our Board adopted the 2014 Equity Compensation Plan, or the 2014 Plan, subject to stockholder approval, which was received on April 1, 2014, pursuant to the terms described herein.

The general purpose of the 2014 Plan is to provide a means whereby eligible employees, officers, non-employee directors and other individual service providers develop a sense of proprietorship and personal involvement in our development and financial success, and to encourage them to devote their best efforts to our business, thereby advancing our interests and the interests of our stockholders. By means of the 2014 Plan, we seek to retain the services of such eligible persons and to provide incentives for such persons to exert maximum efforts for our success and the success of our subsidiaries.

Equity Compensation Plan Information

The following table provides certain information with respect to all of the Corbus equity compensation plans in effect as of December 31, 2016:

In addition, the Audit Committee considered whether the provision of non-audit services by EisnerAmper LLP is compatible with maintaining its independence. In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board of Directors has approved) that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 for filing with the Securities and Exchange Commission.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information as of March 31, 2017 with respect to the beneficial ownership of common stock of the Company by the following: (i) each of the Company’s current directors; (ii) each of the named executive officers; (iii) the current executive officers; (iv) all of the current executive officers and directors as a group; and (v) each person known by the Company to own beneficially more than five percent (5%) of the outstanding shares of the Company’s common stock.

For purposes of the following table, beneficial ownership is determined in accordance with the applicable SEC rules and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as otherwise noted in the footnotes to the table, we believe that each person or entity named in the table has sole voting and investment power with respect to all shares of the Company’s common stock shown as beneficially owned by that person or entity (or shares such power with his or her spouse). Under the SEC’s rules, shares of the Company’s common stock issuable under options that are exercisable on or within 60 days after March 31, 2017 (“Presently Exercisable Options”) are deemed outstanding and therefore included in the number of shares reported as beneficially owned by a person or entity named in the table and are used to compute the percentage of the common stock beneficially owned by that person or entity. These shares are not, however, deemed outstanding for computing the percentage of the common stock beneficially owned by any other person or entity.

The percentage of the common stock beneficially owned by each person or entity named in the following table is based on 50,143,742 shares of common stock issued and outstanding as of March 31, 2017 plus any shares issuable upon exercise of Presently Exercisable Options held by such person or entity.

Except as otherwise noted below, the address for persons listed in the table is c/o Corbus Pharmaceuticals Holdings, Inc., 100 River Ridge Drive, Norwood, Massachusetts 02062. Beneficial ownership representing less than 1% is denoted with an asterisk (*).

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive, officers, and persons who are beneficial owners of more than 10% of a registered class of our equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission. These persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us, and written representations that no other reports were required during the fiscal year ended December 31, 2016, all reports required to be filed under Section 16(a) were filed on a timely basis; except one report covering one transaction was filed late by Barbara White.

Transactions with Related Persons

Other than compensation arrangements for our named executive officers and directors, we describe below each transaction or series of similar transactions, since January 1, 2016, to which we were a party or will be a party, in which:

Compensation arrangements for our named executive officers and directors are described in the section entitled “Executive Compensation.”

Consulting Agreement with Orchestra Medical Ventures

On September 21, 2016, we entered into a consulting agreement with Orchestra Medical Ventures, LLC, or Orchestra, of which David Hochman, our Director, is Managing Partner. The consulting agreement provided that Orchestra would render a variety of consulting and advisory services relating principally to identifying and evaluating strategic relationships, licensing opportunities, and business strategies. Pursuant to the terms of the agreement, we paid to Orchestra cash compensation in an aggregate amount of $100,000, of which $50,000 was paid during fiscal 2016 and the remaining $50,000 was paid in the first quarter of 2017. In addition, as approved by our Compensation Committee, effective as of September 16, 2016, we granted an equity incentive award to Mr. Hochman consisting of options to purchase 50,000 shares (the “Option Shares”) of our common stock (the “Option Award”) pursuant to the 2014 Plan, of which fifty percent (50%) vested on the three (3) month anniversary of the date of grant of the Option Award and the remainder of the Option Shares vested on the six (6) month anniversary of the date of grant of the Option Award. The consulting agreement expired on March 20, 2017.

Indemnification Agreements

In September 2014, we entered into indemnification agreements with our directors and executive officers whereby we have agreed to indemnify those directors and officers to the fullest extent permitted by law, including indemnification against expenses and liabilities incurred in legal proceedings to which the director or officer was, or is threatened to be made, a party by reason of the fact that such director or officer is or was a director, officer, employee or agent of our Company, provided that such director or officer acted in good faith and in a manner that the director or officer reasonably believed to be in, or not opposed to, the best interests of our Company.

Policies and Procedures for Related Party Transactions

Our Board has adopted a policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our common stock, any members of the immediate family of any of the foregoing persons and any firms, corporations or other entities in which any of the foregoing persons is employed or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest, which we refer to collectively as related parties, are not permitted to enter into a transaction with us without the prior consent of our Board acting through the audit committee or, in certain circumstances, the chairman of the audit committee. Any request for us to enter into a transaction with a related party, in which the amount involved exceeds $100,000 and such related party would have a direct or indirect interest must first be presented to our audit committee, or in certain circumstances the chairman of our audit committee, for review, consideration and approval. In approving or rejecting any such proposal, our audit committee, or the chairman of our audit committee, is to consider the material facts of the transaction, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances, the extent of the benefits to us, the availability of other sources of comparable products or services and the extent of the related party’s interest in the transaction.

PROPOSAL 2: ADOPTION OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION, AS AMENDED, TO ELIMINATE THE ABILITY OF STOCKHOLDERS TO ACT BY WRITTEN CONSENT

Our Board believes that it is in the best interests of the Company and our stockholders to amend our current certificate of incorporation, as amended, to eliminate the ability of stockholders to act by written consent. Upon consultation with our management, and our outside legal and financial advisors, our Board unanimously approved, and unanimously recommends for stockholder approval, the proposal to adopt a Certificate of Amendment to our certificate of incorporation, as amended, (the “Certificate of Amendment – Written Consent”) to eliminate the ability of stockholders to act by written consent, the text of which is attached to this Proxy Statement as Appendix A. Additionally, on approval of this Proposal 2, conforming changes will be made to our bylaws.

If our stockholders approve this Proposal 2 in addition to approving the adoption of an amendment to our certificate of incorporation, as amended, to eliminate the ability of stockholders to call special meetings (Proposal 3), then, subject to the approval of the adoption of an amended and restated certificate of incorporation incorporating the amendments pursuant to Proposals 2 and 3 (Proposal 4), we will file with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”) one document that will incorporate such amendments into a single charter document (such document, the “Amended and Restated Certificate of Incorporation”), in lieu of filing each of the Certificate of Amendment – Written Consent and the Certificate of Amendment – Special Meetings (as defined below). The text of the proposed Amended and Restated Certificate of Incorporation is attached to this Proxy Statement as Appendix C. If (i) our stockholders do not approve Proposal 3, but do approve this Proposal 2 or (ii) our stockholders approve Proposals 2 and 3, but not Proposal 4, then the Certificate of Amendment – Written Consent will be filed as an amendment to our current certificate of incorporation with the Delaware Secretary of State.

Section 1 of Article VI of our existing certificate of incorporation, as amended, provides that any action required by law to be taken at any annual or special meeting of our stockholders, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Such section also specifies delivery, timing and notice requirements for such consent. Moreover, our bylaws currently provide for stockholder action by written consent.

The description of the Certificate of Amendment – Written Consent should be read in conjunction with and is qualified in its entirety by reference to the text of the proposed Certificate of Amendment – Written Consent attached to this Proxy Statement as Appendix A.

Reasons for Adopting this Amendment

Our Board is committed to ensuring effective corporate governance policies and practices, which ensure that we are governed with high standards of ethics, integrity and accountability and in the best interest of our stockholders. Our Board, in its continuing review of corporate governance matters, has determined that eliminating our stockholders’ ability to act by written consent will best serve the purposes of the Company and the interests of our stockholders.

In accordance with our commitment to further stockholder enfranchisement, we are seeking to eliminate the ability of stockholders to act by written consent. Accordingly, all stockholders would be entitled to receive notice of any action requiring a vote of stockholders and be afforded the opportunity to have their views taken into account and vote on that action at a duly convened meeting. Our Board believes that the amendment is desirable because it preserves the opportunity for a greater number of stockholders to be heard before any stockholder action is taken. In addition, the amendment would make it difficult for a person who acquires a majority of the outstanding common stock of the Company to approve a merger or sale of the Company or take other action normally requiring a vote of stockholders without providing notice to all stockholders. Finally, our Board believes that the elimination of stockholder action by written consent would promote open negotiations concerning any proposed acquisition of the Company.

In light of the foregoing, our Board believes that amending the provisions of our certificate of incorporation to eliminate stockholder action by written consent is a prudent corporate governance measure to prevent a small number of stockholders from prematurely causing stockholder consideration of a proposal over the opposition of our Board by unilaterally soliciting the consent of stockholders for such a proposal before all of our stockholders have the full benefit of the knowledge, advice and participation of our management and Board.

Elimination of stockholder power to act by written consent may deter certain acquisitions of our stock and may delay, deter or impede stockholder action not approved by our Board. Such actions may include stockholder attempts to obtain control of our Board, unsolicited tender offers or other efforts to acquire control of the Company.

Our certificate of incorporation, as amended, and bylaws currently include certain other provisions that may have an anti-takeover effect, including our Board’s right to issue preferred stock without obtaining additional approval of our stockholders. In addition, Proposal 3 (to eliminate the ability of stockholders to call special meetings) may be deemed to have an anti-takeover effect. Other than Proposal 3, our Board does not currently contemplate recommending the adoption of any other amendments to our certificate of incorporation, as amended, that could be construed to reduce or interfere with the ability of third parties to take over or change the control of our Company. Our Board is not aware of any attempt, or contemplated attempt, to acquire control of the Company.

In deciding to recommend the elimination of our stockholders’ power to act by written consent, our Board considered the arguments against elimination of this power, in particular that elimination of the stockholders’ ability to act by written consent may hinder stockholders’ ability to affect company matters and may have the anti-takeover effect discussed above. After giving careful consideration, our Board determined that the benefits of discouraging hostile bidders and dissident stockholders seeking to further their own special interests from conducting potentially expensive and disruptive consent solicitations outweigh these disadvantages.

Approval Required

The approval of the amendment to eliminate the ability of stockholders to act by written consent requires the affirmative vote of a majority of the shares of the common stock outstanding and entitled to vote for such proposal.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE PROPOSAL TO ADOPT AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION, AS AMENDED, TO ELIMINATE THE ABILITY OF STOCKHOLDERS TO ACT BY WRITTEN CONSENT.

PROPOSAL 3: ADOPTION OF AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION, AS AMENDED, TO ELIMINATE THE ABILITY OF STOCKHOLDERS TO CALL SPECIAL MEETINGS

Our Board believes that it is in the best interests of the Company and our stockholders to amend our current certificate of incorporation, as amended, to eliminate the ability of stockholders to call special meetings. Upon consultation with our management, our outside legal and financial advisors, our Board unanimously approved, and unanimously recommends for stockholder approval, the proposal to adopt a Certificate of Amendment to our certificate of incorporation, as amended, (the “Certificate of Amendment – Special Meetings”) to eliminate the ability of stockholders to call special meetings, the text of which is attached to this Proxy Statement as Appendix B. Additionally, on approval of this Proposal 3, conforming changes will be made to our bylaws.

If our stockholders approve this Proposal 3 in addition to approving the adoption of an amendment to our certificate of incorporation, as amended, to eliminate the ability of stockholders to act by written consent (Proposal 2), then, subject to the approval of the adoption of an amended and restated certificate of incorporation incorporating the amendments pursuant to Proposals 2 and 3 (Proposal 4), we will file with the Delaware Secretary of State the Amended and Restated Certificate of Incorporation, it being one document that will incorporate such amendments into a single charter document, in lieu of filing each of the Certificate of Amendment – Written Consent and the Certificate of Amendment – Special Meetings. The text of the proposed Amended and Restated Certificate of Incorporation is attached to this Proxy Statement as Appendix C. If (i) our stockholders do not approve Proposal 2, but do approve this Proposal 3 or (ii) our stockholders approve Proposals 2 and 3, but not Proposal 4, then the Certificate of Amendment – Special Meetings will be filed as an amendment to our current certificate of incorporation with the Delaware Secretary of State.

Section 2 of Article VI of our existing certificate of incorporation, as amended, provides that a special meeting of stockholders shall be called by our secretary upon the written request, stating the purpose of the meeting, of stockholders who together own of record at least twenty percent (20%) in voting power of the outstanding shares of stock entitled to vote at such meeting. Moreover, our bylaws currently provide for stockholder ability to call special meetings.

The description of the Certificate of Amendment – Special Meetings should be read in conjunction with and is qualified in its entirety by reference to the text of the proposed Certificate of Amendment – Special Meetings attached to this Proxy Statement as Appendix B.

Reasons for Adopting this Amendment

Our Board is committed to ensuring effective corporate governance policies and practices, which ensure that we are governed with high standards of ethics, integrity and accountability and in the best interest of our stockholders. Our Board, in its continuing review of corporate governance matters, has determined that eliminating our stockholders’ power to call special meetings of the stockholders will best serve the purposes of the Company and the interests of our stockholders.

In accordance with our commitment to further stockholder enfranchisement, we are seeking to eliminate the ability of stockholders to call a special meeting. Special meetings are extraordinary events for public companies, can be disruptive, costly and inconsistent with the best interests of all stockholders. Special meetings can cause us to incur substantial expenses in connection with preparing and providing stockholders with proxy materials and can cause significant disruptions to the Company’s normal business operations by requiring significant attention from our management team, diverting their focus from overseeing and operating our business in the best interest of all stockholders. For every special meeting called, we must provide each stockholder with a notice of meeting and proxy materials at significant legal, printing and mailing expenses, as well as incur the other costs normally associated with holding a stockholder meeting. Given that special meetings of stockholders would result in such expenses and disruptions to our business operations, and therefore may not be in the best interests of our stockholders as a whole, our Board believes it is in our stockholders’ best interests if special meetings are only called in the discretion of the Board to consider extraordinary events, when fiduciary, strategic or similar considerations dictate that the matter be addressed on an expedited basis.

Elimination of our stockholders’ power to call a special meeting provides anti-takeover protection for us. A common tactic of bidders attempting a takeover is to initiate a proxy contest by calling a special meeting. By eliminating our stockholders’ right to call a special meeting, expensive proxy contests cannot occur other than in connection with our normally scheduled annual meeting. Our board of directors can still call a special meeting of our stockholders when issues arise that require a stockholder meeting.

Elimination of our stockholders’ power to call a special meeting may deter certain acquisitions of our stock and may delay, deter or impede stockholder action not approved by our Board. Such actions may include stockholder attempts to obtain control of our Board, unsolicited tender offers or other efforts to acquire control of the Company.

Our certificate of incorporation, as amended, and bylaws currently include certain other provisions that may have an anti-takeover effect, including our Board’s right to issue preferred stock without obtaining additional approval of our stockholders. In addition, Proposal 2 (to eliminate the ability of stockholders to act by written consent) may be deemed to have an anti-takeover effect. Other than Proposal 2, our Board does not currently contemplate recommending the adoption of any other amendments to our certificate of incorporation, as amended, that could be construed to reduce or interfere with the ability of third parties to take over or change the control of our Company. The Board is not aware of any attempt, or contemplated attempt, to acquire control of the Company.

In deciding to recommend the elimination of our stockholders’ power to call a special meeting, our Board considered the arguments against elimination of this power, in particular that elimination of our stockholders’ power to call a special meeting may hinder stockholders’ ability to affect company matters and may have the anti-takeover effect discussed above. After giving careful consideration, our Board determined that the benefits of eliminating stockholders’ power to call special meetings outweighed any detriment of such provisions.

Approval Required

The approval of the amendment to eliminate the ability of stockholders to call special meetings requires the affirmative vote of a majority of the shares of the common stock outstanding and entitled to vote for such proposal.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE PROPOSAL TO ADOPT AN AMENDMENT TO OUR CERTIFICATE OF INCORPORATION, AS AMENDED, TO ELIMINATE THE ABILITY OF STOCKHOLDERS TO CALL SPECIAL MEETINGS.

PROPOSAL 4: ADOPTION OF AN AMENDED AND RESTATED CERTIFICATE OF INCORPORATION, WHICH SHALL INCORPORATE THE AMENDMENTS TO OUR CERTIFICATE OF INCORPORATION, AS AMENDED, PURSUANT TO PROPOSALS 2 AND 3, IF BOTH SUCH AMENDMENTS ARE APPROVED

Our Board believes that it is in the best interests of the Company and our stockholders to amend our current certificate of incorporation, as amended, to (i) eliminate the ability of stockholders to act by written consent and (ii) eliminate the ability of stockholders to call special meetings, as described in Proposal 2 and Proposal 3. Upon consultation with our management, and our outside legal and financial advisors, our Board unanimously approved, and unanimously recommends for stockholder approval, subject to the approval of both Proposals 2 and 3, the proposal to adopt the Amended and Restated Certificate of Incorporation, which if approved, will allow us to incorporate such amendments into a single charter document. The text of the proposed Amended and Restated Certificate of Incorporation is attached to this Proxy Statement as Appendix C.

If our stockholders approve this Proposal 4, in addition to Proposals 2 and 3, then we will file the Amended and Restated Certificate of Incorporation with the Delaware Secretary of State, in lieu of filing each of the Certificate of Amendment – Written Consent and the Certificate of Amendment – Special Meetings. If (i) our stockholders approve Proposal 2, but do not approve Proposal 3, (ii) our stockholders approve Proposal 3, but do not approve Proposal 2 or (iii) our stockholders approve Proposals 2 and/or 3, or both, but not this Proposal 4, then the Certificate of Amendment – Written Consent or the Certificate of Amendment – Special Meetings or both, as applicable, will be filed as an amendment or amendments to the Company’s current certificate of incorporation with the Delaware Secretary of State.

The description of the amendments and the summary of the Amended and Restated Certificate of Incorporation should be read in conjunction with and is qualified in its entirety by reference to the text of the proposed Amended and Restated Certificate of Incorporation attached to this Proxy Statement as Appendix C.

The Amended and Restated Certificate of Incorporation will not incorporate any other material changes.

Reasons for Adopting the Amended and Restated Certificate of Incorporation

The principal reason for adopting the Amended and Rested Certificate of Incorporation is to incorporate the amendments as described in Proposal 2 and Proposal 3 into one document and to make other incidental non-material changes. The Amended and Restated Certificate of Incorporation will not incorporate any substantive changes that are not independently approved by our stockholders. Instead, the Amended and Restated Certificate of Incorporation will incorporate our current certificate of incorporation, as amended, and any amendments approved at the Annual Meeting into one document.

For further information regarding the descriptions of, the reasons for and general effect of the amendments, please see the discussions above under “Proposal 2” and “Proposal 3,” as applicable.

Approval Required

The approval of the Amended and Restated Certificate of Incorporation, which shall incorporate the amendments to our certificate of incorporation, as amended, pursuant to Proposals 2 and 3, if both such amendments are approved, requires the affirmative vote of a majority of the shares of the common stock outstanding and entitled to vote for such proposal.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE PROPOSAL TO ADOPT AN AMENDED AND RESTATED CERTIFICATE OF INCORPORATION, WHICH SHALL INCORPORATE THE AMENDMENTS TO OUR CERTIFICATE OF INCORPORATION, AS AMENDED, PURSUANT TO PROPOSALS 2 AND 3, IF BOTH SUCH AMENDMENTS ARE APPROVED.

PROPOSAL 5: RATIFY THE APPOINTMENT OF EISNERAMPER LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2017

The Audit Committee has reappointed EisnerAmper LLP as our independent registered public accounting firm to audit the financial statements of the Company for the fiscal year ending December 31, 2017, and has further directed that management submit their selection of independent registered public accounting firm for ratification by our stockholders at the Annual Meeting. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as public registered accounting firm.

Principal Accountant Fees and Services

The following table summarizes the fees for professional services rendered by EisnerAmper LLP, our independent registered public accounting firm, for each of the last two fiscal years:

Audit Fees

Represents fees, including out of pocket expenses, for professional services provided in connection with the audit of our annual audited financial statements and of our internal control over financial reporting, the review of our quarterly financial statements included in our Forms 10-Q, accounting consultations or advice on accounting matters necessary for the rendering of an opinion on our financial statements, services provided in connection with the offerings of our common stock and audit services provided in connection with other statutory or regulatory filings.

Audit-Related Fees

Audit-related fees are for assurance and other activities not explicitly related to the audit of our financial statements.

The Audit Committee is responsible for appointing, setting compensation and overseeing the work of the independent auditors. The Audit Committee has established a policy regarding pre-approval of all auditing services and the terms thereof and non-audit services (other than non-audit services prohibited under Section 10A(g) of the Exchange Act or the applicable rules of the SEC or the Public Company Accounting Oversight Board) to be provided to us by the independent auditor. However, the pre-approval requirement may be waived with respect to the provision of non-audit services for us if the “de minimus” provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied.

The Audit Committee has considered whether the provision of Audit-Related Fees, Tax Fees, and all other fees as described above is compatible with maintaining EisnerAmper LLP’s independence and has determined that such services for fiscal year 2016 were compatible. All such services were approved by the Audit Committee pursuant to Rule 2-01 of Regulation S-X under the Exchange Act to the extent that rule was applicable.

The Audit Committee is responsible for reviewing and discussing the audit financial statements with management, discussing with the independent registered public accountants the matters required in Auditing Standards No. 16, receiving written disclosures from the independent registered public accountants required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accountants’ communications with the Audit Committee concerning independence and discussing with the independent registered public accountants their independence, and recommending to the Board of Directors that the audit financial statements be included in our annual report on Form 10-K.

Attendance at Annual Meeting

Representatives of EisnerAmper LLP will be present at the Annual Meeting and will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions from stockholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Any Director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the Director for which the vacancy was created or occurred and until such Director’s successor shall have been duly elected and qualified or until his or her earlier resignation, death or removal.

5.     Removal. Subject to the rights, if any, of any series of Preferred Stock to elect Directors and to remove any Director whom the holders of any such stock have the right to elect, any Director (including persons elected by Directors to fill vacancies in the Board of Directors) may be removed from office (i) with cause or without cause and (ii) only by the affirmative vote of the holders of at least a majority in voting power of the shares then entitled to vote at an election of Directors.

If the DGCL is amended after the effective date of this Certificate to authorize corporate action further eliminating or limiting the personal liability of Directors, then the liability of a Director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Any repeal or modification of this Article VII, shall not adversely affect any right or protection existing at the time of such repeal or modification with respect to any acts or omissions occurring before such repeal or modification of a person serving as a Director at the time of such repeal or modification.

The Bylaws of the Corporation may be amended or repealed by the stockholders at any annual meeting of stockholders, or special meeting of stockholders called for such purpose as provided in the Bylaws, by the affirmative vote of the holders of at least a majority in voting power of the outstanding shares entitled to vote on such amendment or repeal, voting together as a single class.

ARTICLE IX
