ABOUT THE MEETING, VOTING, STOCKHOLDER PROPOSALS

AND COMPANY INFORMATION

Delivery and Availability of Proxy Materials

Under U.S. Securities and Exchange Commission (“SEC”) rules, we are furnishing proxy materials to our stockholders primarily via the Internet, instead of mailing printed copies of those materials to each stockholder. Beginning April 10, 2015, we mailed to our stockholders (other than those who previously requested electronic or paper delivery) a notice containing instructions on how to access our proxy materials, including our proxy statement and our annual report. On that date, our proxy statement and our Annual Report (of which our 2014 Annual Report on Form 10-K is a part) were available for review over the Internet at the website listed in the notice. The notice also instructs you on how to access your proxy card to vote through the Internet or by telephone.

This process is designed to expedite stockholders’ receipt of proxy materials, lower the cost of the annual meeting and help conserve natural resources. However, if you would prefer to receive printed proxy materials, please follow the instructions included in the notice. If you have previously elected to receive our proxy materials electronically, you will continue to receive these materials via e-mail unless you elect otherwise.

Matters to be Voted On at the Meeting and Solicitation

By authority of the Board of Directors, Amedica is soliciting your vote to:

Proxy Solicitation

The cost of this solicitation is being borne by Amedica. Proxies may be solicited on our behalf by our directors, officers and regular employees by telephone or other means. There will be no special or additional compensation for these services. Brokerage houses, custodians, nominees and fiduciaries will be requested to forward the soliciting materials to the beneficial owners of record of our common shares, and we will reimburse them for their related charges and expenses. We may also elect to engage a proxy solicitation firm to distribute and solicit proxies.

Persons Entitled to Vote

Stockholders of record at the close of business on March 23, 2015, the record date, are entitled to vote on matters that come before the meeting. Shares can be voted only if the stockholder is present in person or is represented by proxy.

How to Vote

Changing Your Vote

You can change your vote submitted by Internet, telephone or written proxy card by revoking it at any time before it is cast at the annual meeting in one of three ways:

Number of Votes and Quorum

Each share of Amedica’s common stock that you own as of the record date entitles you to one vote. On March 23, 2015 there were 27,167,875 outstanding shares of our common stock all of which are entitled to vote at the annual meeting. The presence of the owners of a majority of the shares entitled to vote at the annual meeting constitutes a quorum. Presence may be in person or by proxy. You will be considered part of the quorum if you attend the annual meeting, vote by Internet or telephone or return a signed and dated proxy card. Abstentions, broker non-votes and shares voted by a broker or bank holding shares for a beneficial owner are counted as present and entitled to vote for determining a quorum.

Required Vote to Approve each Proposal

Board Recommendations on Proposals

The Board recommends a vote FOR approval of the proposed amendment to the Amedica 2012 Equity Incentive Plan, FOR ratification of the appointment of Mantyla McReynolds LLC, and FOR approval of the issuance by the Company, in accordance with a Securities Purchase Agreement dated June 30, 2014, of common stock equal to 20% or more of the Company’s issued and outstanding shares of common stock on June 30, 2014, at a price that may be less than the greater of book or market value of the Company’s common stock.

How Stockholders Can Recommend a Candidate for Election to the Board

Stockholders who wish to recommend a candidate for election to our Board should write to: Corporate Secretary, Amedica Corporation, 1885 West 2100 South, Salt Lake City, UT 84119, stating in detail the qualifications of a candidate for consideration by the Board. In considering Board candidates, the Board seeks individuals of proven judgment and competence who have strong reputations in their respective fields. The Board considers such factors as experience, education, employment history, special talents or personal attributes, anticipated participation in Board activities, and geographic and diversity factors. The process for identifying and evaluating nominees would include detailed consideration of the recommendations and opinions of members of our Board, our executive officers, and our stockholders. There would be no difference in the process of evaluation of candidates recommended by a stockholder and those recommended by other sources.

How to Communicate with the Board

Stockholders interested in communicating directly with our Board may do so by writing to: Board of Directors, Amedica Corporation, 1885 West 2100 South, Salt Lake City, UT 84119. All such written correspondence is delivered to the director or directors to whom it is addressed or, if addressed generally to the Board, to all directors. Concerns relating to accounting, internal controls, or auditing matters are immediately forwarded to the Chief Executive Officer, Principal Accounting Officer, and Chairman of the Audit Committee.

Board Attendance at Annual Meeting

We encourage attendance by members of the board and senior executives, but attendance is not required.

Business Sought to be Presented from the Floor

Stockholders may present proposals for action at a future meeting if they comply with SEC rules, state law and our bylaws. For nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to our Bylaws, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. We have not been notified by any stockholder of his or her intent to present a stockholder proposal from the floor at this year’s Annual Meeting. The enclosed proxy grants the proxy holders discretionary authority to vote on any matter properly brought before this year’s Annual Meeting.

How to Submit a Stockholder Proposal for Inclusion in the 2016 Proxy Statement; Discretionary Voting

Stockholders interested in submitting a proposal for inclusion in our proxy statement for next year’s annual meeting must do so in compliance with our bylaws and applicable SEC rules and regulations. Under Rule 14a-8 adopted by the SEC, to be considered for inclusion in our proxy materials for our 2016 annual meeting, a stockholder proposal must be received in writing by our Secretary no later than 5:00 p.m. MST on Sunday, January 10, 2016. If the date of our 2016 annual meeting is moved more than 30 days before or after the anniversary date of this year’s meeting, the deadline for inclusion of proposals in our proxy statement will instead be a reasonable time before we begin to print and mail our proxy materials next year. Any such proposals will also need to comply with the various provisions of Rule 14a-8, which governs the basis on which such stockholder proposals can be included or excluded from Company-sponsored proxy materials.

If a stockholder desires to submit a proposal for consideration at the 2016 annual meeting, but not have the proposal included with our proxy solicitation materials relating to the 2016 annual meeting, the stockholder must comply with the procedures set forth in our governing documents. Our bylaws require that, for business to be properly brought before an annual meeting by a stockholder, such stockholder must have given timely notice thereof, along with other specified material, in proper written form to the Company. To be timely, a stockholder’s notice pertaining to an annual meeting shall be delivered to the Secretary at the principal executive offices of the Company not less than ninety (90) or more than one-hundred and twenty (120) days prior to the first anniversary of the date of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is more than thirty (30) days before or more than thirty (30) days after the previous year’s annual meeting, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the one-hundred and twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the close of business on the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Corporation.

Any stockholder who wishes to make such a proposal should obtain a copy of the bylaws, which contain these and other requirements with respect to stockholder proposals and director nominations, including certain information that must be included concerning the stockholder and each proposal and nominee. Our bylaws were filed with the SEC as an exhibit to our Periodic Report on Form 8-K, filed on February 20, 2014.

THE BOARD AND ITS COMMITTEES; CORPORATE GOVERNANCE; SECTION 16 COMPLIANCE

The Board and Committees

Our Board of Directors has four members. The Chairman of the Board and our Chief Executive Officer, B. Sonny Bal, MD, PhD, Amedica is a member of the Board and is a full time employee of Amedica. The other three members of the Board, David W. Truetzel, Eric A. Stookey and Jeffrey S. White, are non-employee directors, and the Board has determined that these persons (who constitute a majority of the Board) are “independent directors” under the criteria set forth in Rule 5605(a)(2) of the Nasdaq Listing Rules. The Board met ten (10) times during the year ended December 31, 2014. All directors attended 100% of the meetings of the Board, once elected or appointed to the Board.

Our Board of Directors has three permanent committees: the Audit Committee, the Compensation Committee, and the Corporate Governance and Nominating Committee. The written charters for these committees are on our website at http://investors.amedica.com/corporate-governance.cfm. Our Board of Directors may from time to time establish other standing committees. In addition, from time to time, special committees may be established under the direction of our Board of Directors when necessary to address specific issues.

In 2014, the Board formed a Corporate Governance and Nominating Committee which is appointed by the Board to: (1) identify individuals qualified to serve as members of the Board and, where appropriate, recommend individuals to be nominated by the Board for election by the stockholders or to be appointed by the Board to fill vacancies consistent with the criteria approved by the Board; (2) develop and periodically evaluate and recommend changes to Amedica’s Corporate Governance Guidelines and Code of Ethics, and to review the Company’s policies and programs that relate to matters of corporate responsibility, including public issues of significance to the Company and its stakeholders; and (3) oversee an annual evaluation of the performance of the Board. The current members of the Corporate Governance and Nominating Committee are Eric A. Stookey (Chairman), Jeffrey S. White and David W. Truetzel, and the Board has determined that each of the members of the Corporate Governance and Nominating Committee is “independent” under the standard set forth in Rule 5605(a)(2) of the Nasdaq Listing Rules. The Corporate Governance and Nominating Committee did not meet in 2014. The independent directors of the Board handled corporate governance and nominating

6

duties for the Company during 2014. The Corporate Governance and Nominating Committee operates under a written charter adopted

by the Board of Directors, which sets forth the responsibilities and powers delegated by the Board to the Corporate Governance and Nominating Committee.

The Audit Committee is currently comprised of the following members: David W. Truetzel (Chairman), Eric A. Stookey and Jeffrey S White. The Audit Committee provides oversight for financial reporting matters, internal controls, and compliance with the Company’s financial policies, and meets with its auditors when appropriate. The Audit Committee met six (6) times in 2014, and all director members of the committee attended 100% of the meetings. The Board has determined that David W. Truetzel is an “audit committee financial expert” within the meaning of Item 407(d)(5) of Regulation S-K. Further, the Board has determined that each of David W. Truetzel, Jeffrey S. White and Eric A Stookey are “independent” under the standard set forth in Rule 5605(a)(2) of the Nasdaq Listing Rules. The Audit Committee operates under a written charter adopted by the Board of Directors, which sets forth the responsibilities and powers delegated by the Board to the Audit Committee.

The Compensation Committee of the Board is comprised of the following members: Jeffrey S. White, (Chairman), David W. Truetzel and Eric A. Stookey. The Board has determined that each of David W. Truetzel, Jeffrey S. White and Eric A Stookey are “independent” under the standard set forth in Rule 5605(a)(2) of the Nasdaq Listing Rules. The Compensation Committee recommends to the Board for determination compensation of our executive officers, including the chief executive officer, and addresses salary and benefit matters for other key personnel and employees of the Company. The Compensation Committee met four (4) times in 2014, and all director members of the committee attended 100% of the meetings. The Compensation Committee operates under a written charter adopted by the Board of Directors, which sets forth the responsibilities and powers delegated by the Board to the Compensation Committee.

Corporate Governance Guidelines and Code of Ethics

In 2014, the Board adopted Corporate Governance Guidelines for Amedica. Under the Guidelines, the Audit Committee is required to conduct, at least annually, an appropriate review of all related party transactions for potential conflict of interest situations on an ongoing basis, and all such transactions must be approved by the Audit Committee. For purposes of this review, “related party transactions” means transactions required to be disclosed pursuant to Item 404 of Regulation S-K adopted by the Commission, which are related party transactions we report in this proxy statement.

The bylaws of the Company provide that no contract or transaction between Amedica and one or more of its directors or officers, or between Amedica and any other corporation, firm, association, or other organization in which one or more of its directors or officers are financially interested, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee that authorizes or approves the contract or transaction, or because their votes are counted for such purpose, provided that:

Under the Company’s Code of Ethics, an officer has an obligation to disclose to the Board of Directors or appropriate committee any situation that may present a conflict of interest between Amedica and the officer.

Role of the Board in Risk Oversight

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. Management is responsible for the day-to-day management of the risks that we face, while our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board of Directors is responsible for satisfying itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

Our Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through our Board of Directors as a whole, as well as through various standing committees of the Board of Directors that address risks inherent in their respective areas of oversight. In particular, our Board of Directors is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for us. Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and

7

control these exposures, including guidelines and policies to govern the process by which risk assessment and management is

undertaken. The Audit Committee also monitors oversight of the performance of our internal audit function. Our Corporate Governance and Nominating Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs have the potential to encourage excessive risk-taking.

Audit Committee Report

The Audit Committee has reviewed and discussed the Company’s audited consolidated financial statements as of and for the year ended December 31, 2014 and internal controls over financial reporting with our management and our independent registered public accounting firm. Further, the Audit Committee has discussed with our independent registered public accounting firm the matters required to be discussed under auditing standards generally accepted in the United States, including those matters set forth in Auditing Standard No. 16, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board (the “PCAOB”), other standards of the PCAOB, rules of the SEC, and other applicable regulations, relating to the firm’s judgment about the quality, not just the acceptability, of the Company’s accounting principles, the reasonableness of significant judgments and estimates, and the clarity of disclosures in the consolidated financial statements.

The Audit Committee also has received the written disclosures and the letter from our independent registered public accounting firm required by PCAOB Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, which relate to our independent registered public accounting firm’s independence from our Company, and has discussed with our independent registered public accounting firm its independence from our Company. The Audit Committee has also considered whether the independent registered public accounting firm’s provision of non-audit services to us is compatible with maintaining the firm’s independence. The Audit Committee has concluded that the independent registered public accounting firm is independent from our Company and our management. The Audit Committee has also discussed with our management and our independent registered public accounting firm such other matters and received such assurances from them as it has deemed appropriate.

The Audit Committee also reviewed management’s report on its assessment of the effectiveness of our internal control over financial reporting. In addition, the Audit Committee reviewed key initiatives and programs aimed at strengthening the effectiveness of our internal and disclosure control structure. As part of this process, the Audit Committee continues to monitor the scope and adequacy of our internal auditing program.

Based on the reviews, reports and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board of Directors approved, that our audited consolidated financial statements for the year ended December 31, 2014 and management’s assessment of the effectiveness of our internal control over financial reporting be included in our Annual Report on Form 10-K for the year ended December 31, 2014, for filing with the SEC. The Audit Committee has selected, and the Board of Directors has approved, subject to stockholder ratification, the selection of Mantyla McReynolds LLC as our independent registered public accounting firm for the year ending December 31, 2015.

Respectfully submitted,

David W. Truetzel, Chairman

Section 16(a) Filing Compliance

Section 16(a) of the Securities Exchange Act of 1934 (Exchange Act) requires officers and directors of Amedica and persons who own more than ten percent of a registered class of its equity securities to file reports of ownership and changes in their ownership on Forms 3, 4 and 5 with the Commission, and forward copies of such filings to the Company. To our knowledge, based solely on a review of our records and written representations by the persons required to file these reports, all filing requirements of Section 16(a) were satisfied with respect to our most recent fiscal year, except with respect to one late Form 4 filing concerning certain shares owned by Mr. A Karl Kipke and two Form 4 filings concerning shares owned by David W. Truetzel.

EXECUTIVE COMPENSATION

The following discussion relates to the compensation of our “named executive officers.”

Summary Compensation Table

The following table sets forth information about certain compensation awarded or paid to our named executive officers for the 2013 and 2014 fiscal years.

Narrative Disclosure to Summary Compensation Table

Base Salaries. The base salaries for our named executive officers were determined by our compensation committee after reviewing a number of factors, including:

9

2014 Compensation

On January 27, 2014, our board approved grants of RSUs to our named executive officers in the aggregate amount of 989,350 shares, as detailed below. The RSUs were issued April 1, 2014, the effective date of the registration statement on Form S-8 registering the shares of common stock underlying the RSUs. The RSUs expire three years from the date of grant and vested in November 2014.

Base Salaries for 2014. There were no increases in base salaries for our named executive officers in 2014. This was due to the fact that base salaries for each of the named executive officers were established by the Board in October 2013 and the Board felt that the adjustments made at that time were appropriate to carry forward to 2014.

Executive Retention Program. In August 2014, the Company entered into an Executive Retention Program and Agreement (the “Retention Agreement”) with Eric Olson, Kevin Davis and Kevin Ontiveros. Pursuant to the terms of the Retention Agreement any restricted stock units previously granted to a named executive officer became fully vested upon the earlier to occur of: (i) the Company’s termination of such named executive officer’s employment without cause (and other than due to his death or disability), (ii) the named executive officer’s resignation from his employment with the Company for any reason, (iii) the consummation of a change in control of the Company, and (iv) the expiration of the Lock-Up Agreement previously entered into by such named executive officer and JMP Securities LLC in connection with the Company’s initial public offering and amended on August 8, 2014 (the “Amended Lock-Up Agreement”). Pursuant to the terms of the Amended Lock-Up Agreement, each named executive officer agreed to extend the sale and other restrictions set forth in the Lock-Up Agreement until the earlier of: (i) November 15, 2014 or (ii) the issuance of the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2014. If not previously vested pursuant to the terms of the Retention Agreement, the shares of the Company’s common stock to be issued to a named executive officer upon the vesting of restricted stock units will occur upon the date of the expiration of the Amended Lock-Up Agreement, provided that in the event the window is closed for trading in securities of the Company on such date, then the shares of the Company’s common stock shall not be issued until such date as the trading window is open but in no event later than March 15, 2015.

The Retention Agreement also provided for two retention payments to be made to each named executive officer as well as a the grant of a stock option on August 13, 2014 under the Company’s Amended and Restated 2012 Equity Incentive Plan. The first retention payment is in an amount equal to 15% of his base salary and provides that should the named executive officer terminate his employment with the Company voluntarily prior to December 31, 2014, other than for certain specific reasons, the named executive officer must repay to the Company the net amount of the such retention payment. The second retention payment in an amount equal

to 20% of the named executive officer’s base salary is payable on June 30, 2015 provided that the named executive officer continues to be employed by the Company on that date and has not given notice of his resignation prior to such date. To that effect, Eric K. Olson, the Company’s President and Chief Executive Officer received an initial retention payment in the amount of $52,500 and a stock option award for 150,000 shares of common stock. Kevin Davis, the Company’s Chief Operations Officer, received an initial retention payment in the amount of $33,750 and a stock option award for 100,000 shares of common stock. Kevin Ontiveros, the Company’s Chief Legal Officer, received an initial retention payment in the amount of $37,500 and a stock option award for 100,000 shares of common stock. The option awards vest over a three year period as to 16.67% of the shares on every 6 month anniversary of the grant date as long the executive is employed by the Company on each vesting date and vesting shall be accelerated as per the terms of this Agreement. The option exercise price is equal to the Fair Market Value (as defined in the Plan) of a share of common stock as of the grant date. The option terminates on the sooner of the 90 day anniversary of termination of employment or 10 years from the date of award.

In January 2013, we offered to each employee and director that held options to acquire shares of our common stock awarded under the 2003 Plan the opportunity to exchange such options for RSUs to be issued under the 2012 Plan on a one-for-one basis. As a result of the exchange offer, 93,968 RSUs were issued under the 2012 Plan in February 2013. Messrs. Olson and Davis exchanged stock options and received 23,279 and 6,790 RSUs, respectively. Mr. Moyes and Mr. Ontiveros did not have options eligible for conversion. The RSUs have all vested.

In June 2013, in lieu of granting stock options, our board approved a grant of RSUs under the 2012 Plan to our named executive officers. Messrs. Olson, Davis and Ontiveros received 1,940, 970 and 970 RSUs, respectively. The RSUs have all vested.

On October 27, 2013, our board approved the hiring of Mr. Moyes as our Chief Financial Officer at an annual base salary of $325,000 and provided Mr. Moyes with a signing bonus of $100,000 which was paid on his first day of employment. In connection with his hiring, our board approved a grant of 58,197 RSUs to Mr. Moyes under the 2012 Plan, of which (i) 19,399 RSUs vested on his first day of employment, (ii) 19,399 RSUs vested on January 27, 2014 and (iii) 19,399 RSUs vested on February 12, 2014. Mr. Moyes left the employ of the Company in August 2014 and forfeited all of his RSUs back to the Company.

Our board authorized salary increases for each of our named executive officers effective as of October 30, 2013. Accordingly, Mr. Olson’s salary was increased from $300,000 to $350,000, Mr. Davis’s salary was increased from $185,000 to $225,000 and Mr. Ontiveros’s salary was increased from $225,000 to $250,000. Mr. Moyes did not receive a salary increase as he had just begun his employment with the Company at the time of salary increases.

Mr. Davis was awarded a bonus in 2013 in the amount $26,201 for achievement of certain corporate objectives.

Outstanding Equity Awards at Fiscal Year-End

The following table shows information regarding equity awards held by our named executive officers as of December 31, 2014:

401(k) Plan

We offer our executive officers, including our named executive officers, retirement benefits, including participation in our tax-qualified profit sharing plan that includes a “cash-or-deferred” (or 401(k)) feature in the same manner as other employees. The plan is intended to satisfy the requirements of Section 401 of the Internal Revenue Code. Our employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit and have a like amount contributed to the plan. In addition, we may make discretionary and/or matching contributions to the plan in amounts determined annually by our board. We currently elect to match the contributions of our employees who participate in our 401(k) plan as follows: a match of 100% on the first 3% of

compensation contributed by a plan participant and a match of 50% on amounts above 3%, up to 5%, of compensation contributed by a plan participant.

Potential Payments upon Termination or Change in Control

We had entered into certain agreements and maintained certain plans that may have required us to make certain payments and/or provide certain benefits to the executive officers named in the Summary Compensation Table in the event of a termination of employment or change in control. Because none of the named executive officers are currently employed by the Company all of such agreements and plans have been terminated and are no longer in effect for such named executive officers.

Code of Ethics Violations

It is our policy under our Code of Ethics to take appropriate action against any executive officer whose actions are found to violate the Code or any other policy of Amedica. Disciplinary actions may include immediate termination of employment and, where Amedica has suffered a loss, pursuing its remedies against the executive officer responsible. Amedica will cooperate fully with the appropriate authorities where laws have been violated.

Warrant Restructuring and Private Placement of Common Stock

In March 2013, we amended the terms of certain of the common stock warrants issued in connection with the issuance of the Senior Secured Notes to further lower the exercise prices thereof from $25.77 per share to $17.53 per share. We then issued an aggregate of 178,516 shares of our common stock to 33 accredited investors upon exercise of the amended common stock warrants and the sale of additional shares of our common stock to other investors in the offering at $17.53 per share. We also issued to investors who exercised their common stock warrants new warrants to purchase an aggregate of 76,455 shares of our common stock at an exercise price of $17.53 per share. We issued an aggregate of 53,347 shares of our common stock and new warrants to purchase up to 17,773 shares of our common stock at an exercise price of $17.53 per share to the following directors, officers and beneficial owners of more than 5% of our common stock at the time of the transaction, on an as converted basis, and their affiliates:

Honigblum, the Chief Executive Officer and a 50% co-owner of each of Creation Capital LLC, or Creation Capital, and Creation Capital Advisors, LLC, or Creation Advisors, served on our board of directors from 2006 until September 2013. In connection with the private placement of our Senior Secured Notes Creation Capital served as our placement agent In February 2012, when we issued an additional $5.0 million Senior Secured Note to Hampshire Med Tech Partners, LP, we paid Creation Capital an $212,500 as commissions.

In connection with the conversion of our Senior Secured Notes in December 2012, we agreed to pay Creation Advisors a strategic financial advisory fee in the amount of approximately $447,000. We agreed to pay half of the advisory fee, approximately $223,000 in December 2012 and the remaining half within 24 months, which we paid in September 2013. Karl Kipke, who beneficially owned more than 5% of our common stock at that time, received $60,000 from Creation Advisors in 2012, as a consultant for Creation Advisors, for advising us at this time on our financing options.

In connection with the warrant restructuring and private placement of common stock in March 2013, we paid Creation Advisors a strategic financial advisory fee of approximately $250,000. In October 2013, we entered into a one-year consulting agreement for financial advisory services with Creation Advisors in which Creation Advisors received compensation of up to $180,000 in cash (payable $15,000 per month). We paid $45,000, under this agreement, during the year ended December 31, 2013. We paid $45,000 under this agreement during the year ended December 31, 2014. This agreement was terminated in March 2014 and as consideration for termination of the agreement, the Company paid $60,000 and issued 50,000 restricted shares of common stock, valued at $372,000, to Creation Advisers.

PROPOSAL NO. 1

INCREASE NUMBER OF SHARES AVAILABLE FOR AWARDS UNDER THE 2012 EQUITY INCENTIVE PLAN

The Amedica 2012 Equity Incentive Plan (the “2012 Plan”) was adopted by our Board in September 2012 and approved by our stockholders by written consent on February 5, 2014. In November 2013 and January 2014 our Board subsequently approved certain amendments to the 2012 Plan which were approved by the stockholders in February 2014.

The Board believes that stock-based incentives are essential to attract and retain the services of individuals who are likely to make significant contributions to our success, to encourage ownership of our common stock by employees and directors, and to promote our success by providing both rewards for exceptional performance and long-term incentives for future contributions to the Company.

The 2012 Plan currently authorizes the issuance of up to 3,568,181 shares of common stock (or 12% of outstanding shares at March 31, 2015) pursuant to awards granted under the Plan. Of those shares, 3,202,106 have been issued or are subject to outstanding awards, leaving only 366,875 shares available for future awards. The Board of Directors does not believe that the number of shares available for issuance under the 2012 Plan is sufficient in light of our compensation strategy and objectives. Accordingly, the Board is proposing to increase the number of shares available under the 2012 Plan by 1,000,000 shares, from 3,568,181 to 4,568,181, increasing the percentage ratio of the amount of shares available under the Plan to 5% of outstanding shares as of March 31, 2015.

The Board recommends that shareholders approve amendment of the Plan in order to allow the Company to continue to offer stock options and alternative equity awards to employees, directors and consultants as part of its overall compensation package. The material features of the 2012 Plan are summarized below.

Material Features of the 2012 Plan

The 2012 Plan is intended to encourage ownership of common stock by our employees and directors and certain of our consultants in order to attract and retain such people, to induce them to work for the benefit of us and to provide additional incentive for them to promote our success. The number of shares of our common stock reserved for issuance under the 2012 Plan is 3,000,000, which number is automatically increased on January 1 of each of year by the lesser of (i) 568,181 shares of our common stock on such date, (ii) 5% of the number of outstanding shares of our common stock on such date, and (iii) such other amount determined by the board through the termination of the 2012 Plan.

Types of Awards. The 2012 Plan provides for the granting of incentive stock options, NQSOs, stock grants and other stock-based awards, including RSUs.

16

Plan Administration. Our board is the administrator of the 2012 Plan, except to the extent it delegates its authority to a committee, in which case the committee shall be the administrator. Our board has delegated this authority to our compensation committee. The administrator has the authority to determine the terms of awards, including exercise and purchase price, the number of shares subject to awards, the value of our common stock, the vesting schedule applicable to awards, the form of consideration, if any, payable upon exercise or settlement of an award and the terms of award agreements for use under the 2012 Plan.

Eligibility. Our board will determine the participants in the 2012 Plan from among our employees, directors and consultants. A grant may be approved in advance with the effectiveness of the grant contingent and effective upon such person’s commencement of service within a specified period.

Termination of Service. Unless otherwise provided by our board or in an award agreement, upon a termination of a participant’s service, all unvested options then held by the participant will terminate and all other unvested awards will be forfeited.

Transferability. Awards under the 2012 Plan may not be transferred except by will or by the laws of descent and distribution, unless otherwise provided by our board in its discretion and set forth in the applicable agreement, provided that no award may be transferred for value.

Adjustment. In the event of a stock dividend, stock split, recapitalization or reorganization or other change in change in capital structure, our board will make appropriate adjustments to the number and kind of shares of stock or securities subject to awards.

Corporate Transaction. If we are acquired, our board of directors (or compensation committee) will: (i) arrange for the surviving entity or acquiring entity (or the surviving or acquiring entity’s parent company) to assume or continue the award or to substitute a similar award for the award; (ii) cancel or arrange for cancellation of the award, to the extent not vested or not exercised prior to the effective time of the transaction, in exchange for such cash consideration, if any, as our board of directors in its sole discretion, may consider appropriate; or (iii) make a payment, in such form as may be determined by our board of directors equal to the excess, if any, of (A) the value of the property the holder would have received upon the exercise of the award immediately prior to the effective time of the transaction, over (B) any exercise price payable by such holder in connection with such exercise. In addition in connection with such transaction, our board of directors may accelerate the vesting, in whole or in part, of the award (and, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such transaction and may arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by us with respect to an award.

Amendment and Termination. The 2012 Plan will terminate on September 6, 2022 or at an earlier date by vote of the stockholders or our board; provided, however, that any such earlier termination shall not affect any awards granted under the 2012 Plan prior to the date of such termination. The 2012 Plan may be amended by our board, except that our board may not alter the terms of the 2012 Plan if it would adversely affect a participant’s rights under an outstanding stock right without the participant’s consent. Stockholder approval will be required for any amendment to the 2012 Plan to the extent such approval is required by law, include the Internal Revenue Code or applicable stock exchange requirements.

Amendment of Outstanding Awards. The administrator may amend any term or condition of any outstanding award including, without limitation, to reduce or increase the exercise price or purchase price, accelerate the vesting schedule or extend the expiration date, provided that no such amendment shall impair the rights of a participant without such participant’s consent.

Federal Income Tax Consequences of the Plan

The federal income tax consequences of grants under the Plan will depend on the type of grant. The following description provides only a general description of the application of federal income tax laws to grants under the Plan. This discussion is intended for the

17

information of stockholders considering how to vote at the Annual Meeting and not as tax guidance to grantees, as the consequences may vary with the types of grants made, the identity of the grantees and the method of payment or settlement. The summary does not address the effects of other federal taxes (including possible “golden parachute” excise taxes) or taxes imposed under state, local, or foreign tax laws.

From the grantees’ standpoint, as a general rule, ordinary income will be recognized at the time of delivery of shares of our common stock or payment of cash under the Plan. Future appreciation on shares of our common stock held beyond the ordinary income recognition event will be taxable as capital gain when the shares of our common stock are sold. The tax rate applicable to capital gain will depend upon how long the grantee holds the shares. We, as a general rule, will be entitled to a tax deduction that corresponds in time and amount to the ordinary income recognized by the grantee, and we will not be entitled to any tax deduction with respect to capital gain income recognized by the grantee.

Exceptions to these general rules arise under the following circumstances:

Section 162(m) of the Code generally disallows a publicly held corporation’s tax deduction for compensation paid to its chief executive officer or certain other officers in excess of $1 million in any year. Qualified performance-based compensation is excluded from the $1 million deductibility limit, and therefore remains fully deductible by the corporation that pays it. We intend that options and SARs granted under the Plan will be qualified performance-based compensation. Stock units, stock awards, dividend equivalents, and other stock-based awards granted under the Plan may be designated as qualified performance-based compensation if the Committee conditions such grants on the achievement of specific performance goals in accordance with the requirements of section 162(m) of the Code.

We have the right to require that grantees pay to us an amount necessary for us to satisfy our federal, state or local tax withholding obligations with respect to grants. We may withhold from other amounts payable to a grantee an amount necessary to satisfy these obligations. The Committee may permit a grantee to satisfy our withholding obligation with respect to grants paid in shares of our common stock by having shares withheld, at the time the grants become taxable, provided that the number of shares withheld does not exceed the individual’s minimum applicable withholding tax rate for federal, state and local tax liabilities.

The affirmative vote of the holders of a majority of the common shares voted on the proposal and represented at the annual meeting in person or by proxy is required to approve the amendment to the 2012 Plan. The Board of Directors recommends that you vote FOR this proposal.

Ratification of the selection of Mantyla McReynolds LLC is not required by our bylaws or otherwise. The Board is submitting the selection to our stockholders for ratification as a matter of good corporate practice. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different registered public accounting firm at any time after the annual meeting if it determines such a change would be in the interests of Amedica and its stockholders.

Accountant Fees and Services

The aggregate fees and expenses from our principal accounting firms, Mantyla McReynolds LLC for 2014 and Ernst and Young LLP for 2013, for fees and expenses incurred during fiscal years ended December 31, 2014 and 2013, were as follows (in thousands):

Each of the permitted non-audit services has been pre-approved by the Audit Committee or the Audit Committee’s Chairman pursuant to delegated authority by the Audit Committee, other than de minimus non-audit services for which the pre-approval requirements are waived in accordance with the rules and regulations of the Securities and Exchange Commission.

Policy for Approval of Audit and Permitted Non-Audit Services

The Audit Committee charter provides that the Audit Committee will pre-approve audit services and non-audit services to be provided by our independent auditors before the accountant is engaged to render these services. The Audit Committee may consult with management in the decision-making process, but may not delegate this authority to management. The Audit Committee may delegate its authority to pre-approve services to one or more committee members, provided that the designees present the pre-approvals to the full committee at the next committee meeting.

The affirmative vote of the holders of a majority of the common shares voted on the proposal and represented at the annual

PROPOSAL NO. 3

APPROVAL OF THE ISSUANCE BY THE COMPANY, IN ACCORDANCE WITH A SECURITIES PURCHASE AGREEMENT DATED JUNE 30, 2014, OF COMMON STOCK EQUAL TO 20% OR MORE OF THE COMPANY’S ISSUED AND OUTSTANDING COMMON STOCK ON JUNE 30, 2014 AT A PRICE THAT MAY BE LESS THAN THE GREATER OF BOOK OR MARKET VALUE OF THE COMPANY’S COMMON STOCK.

Terms of the Transaction

On June 30, 2014, we entered into a securities purchase agreement (the “Purchase Agreement”), with MG Partners II Ltd., an affiliate of Magna (the “Investor”). Pursuant to the Purchase Agreement, the Company sold the Investor an initial unsecured senior convertible note with an original principal amount of $2.9 million (the “Initial Convertible Note”), for a purchase price of $2.5 million. Subsequently, upon satisfaction of certain conditions set forth in the Purchase Agreement, the Company sold the Investor an additional unsecured senior convertible note with an original principal amount of $3.5 million (the “Additional Convertible Note” and, with the Initial Convertible Note, referred to herein collectively as, the “Convertible Notes”), for a fixed purchase price of $3.5 million.

With respect to the Initial Convertible Note, a total of $400,000 of the outstanding principal amount was automatically extinguished (without any cash payment by the Company) in August 2014 due to satisfaction of certain covenants by the Company contained in the Purchase Agreement.

In addition, in connection with the Purchase Agreement, the Company issued the Investor a warrant (the “Warrant”) to purchase up to 568,889 shares of Common Stock at an exercise price of $4.65 per share. The Warrant was to expire on June 30, 2016.

On April 1, 2015, we entered into an Amendment and Exchange Agreement (the “Amendment Agreement”) with the Investor providing for the issuance of a new senior convertible note in the principal amount of $6.4 million (the “Exchange Convertible Note”) in exchange for the original Convertible Notes and the Warrant. As a result, the Convertible Notes and the Warrant were cancelled. The principal terms of the Exchange Convertible Note and the Purchase Agreement, as amended by the Amendment Agreement, are provided below.

Description of the Exchange Convertible Note

The Exchange Convertible Note matures on June 30, 2016, provided however, that if, as of June 30, 2016, the Company has satisfied certain equity conditions described below, the maturity date shall be extended to June 30, 2017. The equity conditions include requirements that: there be an effective registration statement covering the sale of the shares of common stock received in a conversion by the Investor or that such shares be eligible for resale under Rule 144 of the Securities Exchange Act of 1933, as amended; that the shares be listed on an eligible exchange or designated for quotation, as applicable; and, that the stockholders shall have approved a resolution providing for the issuance of all the shares of common stock issuable in the transaction. The Exchange Convertible Note accrues interest at an annual rate of 6.0%.

The Exchange Convertible Note is convertible at any time after issuance, in whole or in part, at the Investor’s option, into shares of Common Stock at an initial conversion price equal to $1.00 per share provided that that if on May 29, 2015, 120% of the quotient of (x) the sum of the volume weighted average price (“VWAP”) of the Common Stock of each Trading Day during the five (5) Trading Day period ending on and including the Trading Day immediately prior to May 29, 2015, divided by (y) five (5) is greater than $1.00, then that price shall be the Conversion Price then in effect. Additionally, the Exchange Convertible Note may not be converted at a price less than $0.20 per share. The Exchange Convertible Note provides that with respect to each conversion notice delivered by Investor to Company, the Investor shall be able to convert the Exchange Convertible Note, in whole or in part, at a price equal to the greater of (x) $0.20 and (y) the lower of (i) the Conversion Price and (ii) a price equal to 80% of the lowest daily VWAP of the Common Stock during the five (5) consecutive Trading Day period prior to such Conversion Date (the “Alternate Conversion Price”).

The Exchange Convertible Note also provides that in the event on any conversion date, the applicable conversion price for that date is greater than the closing bid price as of the trading day immediately preceding such applicable conversion date (a “Make-Whole conversion”) then the Investor shall be entitled to additional shares of common stock should the Investor subsequently sell the shares issued in the conversion for a price less than the conversion price used on the conversion date. The number of shares to be issued shall equal the greater of zero and the quotient of (1) the difference of the (x) the aggregate amount of principal and interest of the Exchange Convertible Note converted into common shares during a quarter in which a Make-Whole Conversion occurred (less any conversion amount relating to shares of common stock that have not been resold during that quarter) minus (y) the aggregate gross consideration received by the Investor on the resale of any common shares received by the Investor on conversions occurring during that quarter divided by (2) the Alternate Conversion Price on the date of the Make-Whole Conversion.

20

As long as the Exchange Convertible Note is outstanding and for so long as the Investor or its affiliates beneficially own any of the shares of Common Stock issuable upon conversion of the Exchange Convertible Note, they may not engage in any “short sale” transactions in the Common Stock. In addition, the Investor has agreed that unless otherwise mutually agreed upon, the Investor, upon conversion of the Exchange Convertible Note, shall not sell more than the greater of: (i) $125,000 of Common Stock, in any five (5) consecutive trading day period, or (ii) 15% of the daily trading volume of the Common Stock on any given trading day. If, however, on any given trading day more than $250,000 of the Common Stock is traded, the Investor may trade up to 33% of the daily trading volume on that day (the “Investor Restrictions”). Furthermore, the Investor Restrictions will be removed on any day the price of the stock trades below $0.50.

The Exchange Convertible Note includes customary event of default provisions. The Exchange Convertible Note provides for a default interest rate of 18%. Upon the occurrence of an event of default, Investor may require the Company to pay in cash the “Event of Default Redemption Price” which is defined in the Exchange Convertible Note to mean the greater of (i) the product of (A) the amount to be redeemed multiplied by (B) 135% (or 100% if an insolvency related event of default) and (ii) the product of (X) the conversion price in effect at that time multiplied by (Y) the product of (1) 127.5% (or 100% if an insolvency related event of default) multiplied by (2) the greatest closing sale price of the common stock on any trading day during the period commencing on the date immediately preceding such event of default and ending on the date the Company makes the entire payment required to be made under the default provision.

The Company has the right to prepay the Exchange Convertible Note, in whole or in part, for an amount equal to 127.5% of the outstanding principal remaining.

The Purchase Agreement.

The Company paid the Investor a commitment fee for entering into the Purchase Agreement equal to 4% of the total purchase price for the Convertible Notes under the Purchase Agreement in the form of the issuance of 50,853 shares of Common Stock (the “Commitment Shares”), calculated using a per share price of $4.7195, representing the VWAP of the Common Stock per share on June 27, 2014.

Under the Purchase Agreement, as amended, if at any time the aggregate number of Commitment Shares, shares of Common Stock issuable upon conversion of the Exchange Convertible Note (the “Conversion Shares”) is 15% or more of the total shares of the Common Stock outstanding on the date of the Purchase Agreement, then at the next special or annual meeting of stockholders of the Company, the Company is required to take all action necessary to obtain the approval of its stockholders of the issuance of all Commitment Shares and Conversion Shares in accordance with the rules of the NASDAQ Stock Market. If, despite the Company’s commercially reasonable efforts such stockholder approval is not obtained, the Company is required to seek to obtain stockholder approval at each special or annual meeting of stockholders of the Company convened such meeting until such stockholder approval is obtained. In addition, until stockholder approval is obtained, the Company may not issue any common shares in an aggregate amount that exceeds 19.99% of the issued and outstanding Common Stock on the date of the Purchase Agreement.

The Company also agreed, among other things, to indemnify the Investor from certain liabilities and fees and expenses of the Investor incident to the Company’s obligations under the Registration Rights Agreement, including certain liabilities under the Securities Act. The Investor has agreed to indemnify and hold harmless the Company and each of its directors, officers and persons who control it against certain liabilities that may be based upon written information furnished by the Investor to the Company for inclusion in a Registration Statement pursuant to the Registration Rights Agreement, including certain liabilities under the Securities Act.

Why the Company Needs Stockholder Approval

Our common stock is listed on the Nasdaq Capital Market and, as such, we are subject to the Nasdaq Marketplace Rules. Nasdaq Marketplace Rule 5635(d) is referred to as the “Nasdaq 20% Rule.” The Nasdaq 20% Rule requires that an issuer obtain stockholder approval prior to certain issuances of common stock or securities convertible into or exchangeable for common stock at a price less than the greater of market price or book value of such securities (on an as exercised basis) if such issuance equals 20% or more of the common stock or voting power of the issuer outstanding before the transaction. Shares of our common stock that were issued as part of the Commitment Shares, shares of common stock that have been issued on previous conversions of the Exchange Convertible Note into common shares and shares of common stock that might be issued upon subsequent conversion of the Exchange Convertible Note are considered common stock issued for the purposes of determining whether the 20% limit has been reached.

On June 30, 2014, the aggregate number of shares of common stock outstanding was 12,360,354. Pursuant to the Securities Purchase Agreement we cannot issue to the Investor greater than 19.99% of the issued and outstanding shares of common stock on June 30, 2014 or 2,470,835 shares, without first obtaining stockholder approval to exceed the Nasdaq 20% Rule. As of March 31, 2015 the Company has issued to the Investor a total of 2,470,835 shares of common stock thereby reducing the principal balance of the Exchange Convertible Note from $6.4 million to approximately $4.3 million. Due to the Nasdaq 20% Rule, we are precluded from issuing any additional shares of common stock to the Investor to reduce the balance owing on the Exchange Convertible Note. Accordingly, we need stockholder approval for the potential issuance of more than 20% of the Company’s issued and outstanding common stock at a price that may be less than the greater of book or market value of the Company’s common stock as of June 30, 2014.

In order to comply with the Nasdaq 20% Rule we are seeking stockholder approval for the potential issuance of securities in excess of the Nasdaq limitations.

We did not seek advance stockholder approval of the potential issuances of shares of common stock related to the Purchase Agreement because the Purchase Agreement restricts the number of shares that can be issued upon conversion of the Exchange Convertible Note into common stock, to an amount that would not be in excess of the applicable Nasdaq limitations. Therefore, stockholder approval was not required by the Nasdaq Marketplace Rules. If stockholders do not approve Proposal No. 3 at the Annual Meeting, this limit will remain in place.

No Dissenters’ Rights

Under applicable Delaware law, our stockholders are not entitled to dissenters’ or appraisal rights with respect to the approval of the issuance of the shares of common stock pursuant to the Purchase Agreement.

Effect of Proposal No. 3 on Current Stockholders

If Proposal No. 3 is adopted, the Company would be able to issue shares of common stock in excess of 19.99% of our outstanding shares of common stock in connection with subsequent conversion of the Exchange Convertible Note into common shares. The issuance of such shares could result in significant dilution to our stockholders, and afford them a smaller percentage interest in the voting power, liquidation value and aggregate book value of the Company. Additionally, the sale or any resale into the public markets of the common stock issued in connection the conversion could cause the market price of our common stock to decline.

If Proposal 3 is not adopted then the Investor will be precluded from converting any of the remaining principal balance of the Exchange Convertible Note into common shares thereby reducing the principal balance of the note and the Company will be required to pay the remaining principal and interest owing out of its own cash resources on the maturity date of the note, June 30, 2016.
