THIS SERIES E WARRANT AGREEMENT (this “Warrant Agreement”) dated April 7, 2010, is made by and between ZIONS FIRST NATIONAL BANK, (“Zions”), and AMEDICA CORPORATION, a Delaware corporation (“Amedica”). Zions and Amedica are each referred to herein as a “Party” and collectively, the “Parties.”

WHEREAS, the Parties have entered into an Amended and Restated Loan Agreement dated April 7, 2010 (the “Loan Agreement”) which increases the maximum amount Amedica may borrow under its senior secured credit facility to up to $10,000,000, consisting of a $7,500,000 term loan and a $2,500,000 line of credit that may be increased by $5,000,000 upon certain terms and conditions and lender’s subsequent approval; and

WHEREAS, the Loan Agreement provides that Zions shall receive a warrant to purchase 50,000 shares of Series E Convertible Preferred Stock, par value $0.01 per share (the “Stock”); and

WHEREAS, the Loan Agreement further provides that the warrant shall be issued pursuant to a definitive warrant agreement mutually agreed to by Amedica and Zions.

NOW, THEREFORE, in consideration of the premises and the mutual agreements hereinafter set forth and for the purposes of defining terms and provisions of the Warrant and the certificate representing the Warrant and the respective rights and obligations thereunder of Amedica, Zions and the holder of a certificate representing the Warrant, Amedica and Zions hereby agree as follows:

Section 1. Form of Warrant. Amedica shall grant to Zions (Zions and/or its permitted assigns are collectively referred to herein as the “Holder”) warrant(s) (the “Warrant”), in the form of Exhibit A hereto, to purchase shares of Stock at a purchase price of $2.20 per share (the “Exercise Price”) all as more fully set forth herein. The Warrant shall be executed on behalf of Amedica by its Chief Financial Officer or any other authorized officer of Amedica, and dated as of the date of issuance of the Warrant.

Section 2. Exercise Period of Warrant. The Warrant shall be exercisable at any time commencing on the first anniversary of the date of issuance of the Warrant and shall terminate at 5:00 p.m., New York City Time, on April 7, 2015 (the “Warrant Termination Date’’); provided, however, that in the event of (a) the closing of the issuance and sale of shares of the common stock, $0.01 par value per share (the “Common Stock”), of Amedica in Amedica’s first underwritten public offering (“IPO”) pursuant to an effective registration statement under the Securities Act of 1933, as amended (the ‘‘Securities Act”) or (b) a Change of Control (as defined below), the Warrant shall, on the date of such event, become immediately exercisable.

A “Change of Control” shall mean any acquisition of capital stock of Amedica, directly or indirectly, any merger, tender offer, recapitalization or asset sale pursuant to which Amedica’s stockholders immediately prior to such transaction hold less than 50% of the voting securities of the surviving corporation immediately after such transaction or the majority of the assets of Amedica are transferred or sold, except that any internal re-structuring or re-organization of Amedica that does not change the effective ultimate ownership of Amedica shall not be deemed a Change of Control.

Section 3. Term of Warrant Agreement. Except as otherwise expressly provided herein, this Warrant Agreement shall become void and all rights hereunder and all rights in respect thereof under the Warrant shall cease as of the Warrant Termination Date except to the extent that the Warrant is exercised prior to such date.

Section 4. Number of Shares. The Warrant shall be exercisable for up to the number of shares of Stock determined in accordance with the terms of the Loan Agreement, and such number shall be indicated on the Warrant, and which shall be subject to adjustment as provided herein (the “Warrant Shares”).

Section 5. Adjustment Provisions. The Exercise Price and the number of shares of Stock underlying the Warrant shall be subject to adjustment from time to time as hereinafter set forth:

(a) Stock Dividends – Stock Splits. If after the date hereof, the number of outstanding shares of Stock is increased by a stock dividend payable in shares of Stock or by a sub-division or a stock split of shares of Stock or other similar event as described in the Certificate of Designation, Preferences and Rights of the Stock, as amended from time to time (the “Certificate of Designation”), then, on the effective date thereof, the number of shares of Stock issuable on exercise of the Warrant shall be increased in proportion to such increase in outstanding shares.

(b) Aggregation of Shares. If after the date hereof, the number of outstanding shares of Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Stock or other similar event, then, on the effective date thereof, the number of shares of Stock issuable on exercise of the Warrant shall be decreased in proportion to such decrease in outstanding shares.

(c) Adjustments in Exercise Price. Whenever the number of the shares of Stock issuable upon the exercise of the Warrant is adjusted, as provided in Sections 5(a) and (b). the Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of the shares of Stock purchasable upon the exercise of the Warrant immediately prior to such adjustment and (y) the denominator of which shall be the number of the shares of Stock so purchasable immediately thereafter.

(d) When De Minimis Adjustment May Be Deferred. No adjustment in the Exercise Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Exercise Price. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 5 shall be made to the nearest 1/100^th of a share.

- 2 -

(e) Notice. Whenever there shall be an adjustment as provided in this Section 5. Amedica shall promptly cause written notice thereof to be sent to the Holder in accordance with Section 9 hereof, which notice shall be accompanied by an officer’s certificate setting forth the number of Warrant Shares purchasable upon the exercise of the Warrant and the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation thereof. Additionally, in case at any time Amedica shall propose:

(i) to pay any dividend or make any distribution on shares of Stock in shares of Stock or make any other distribution to all holders of Stock; or

(ii) to issue any rights, warrants or other securities to all holders of Stock entitling them to purchase any additional shares of Stock or any other rights, warrants or other securities; or

(iii) to effect any reclassification or change of outstanding shares of Stock, or any consolidation, merger or sale; or

(iv) to effect any liquidation, dissolution or winding-up of Amedica;

then, and in any one or more of such cases, Amedica shall give written notice thereof to the Holder in accordance with Section 9 hereof, which notice shall be sent at least fifteen (15) days prior to (i) the date as of which the holders of record of shares of Stock to be entitled to receive any such dividend, distribution, rights, warrants, other securities are to be determined or (ii) the date on which any such reclassification, change of outstanding shares of Stock, consolidation, merger, sale, liquidation, dissolution or winding-up is expected to become effective, and the date as of which it is expected that holders of record of shares of Stock shall be entitled to exchange their shares for securities or other property, if any, deliverable upon such reclassification, change of outstanding shares, consolidation, merger, sale, liquidation, dissolution or winding-up.

Section 6. Representations, Warranties and Covenants of Amedica. Amedica hereby represents, warrants and covenants to Holder as follows:

(a) Amedica is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and is in good standing as a foreign corporation in each jurisdiction in which the nature of its business makes such qualification necessary and where the failure to so qualify would have a material adverse effect on its business or operations. Amedica has all requisite corporate power and authority to carry out its business as presently conducted and as proposed to be conducted and to enter into and discharge its obligations under this Warrant Agreement and the Warrant.

(b) The execution and delivery of this Warrant Agreement and the Warrant by Amedica and its performance and compliance with the terms of this Warrant Agreement and the Warrant have been duly authorized by all necessary corporate action on the part of Amedica.

(c) The consummation of the transactions contemplated by this Warrant Agreement and the Warrant will not (i) conflict with, result in any breach of any of the terms and provisions of, or constitute (with or without notice or lapse of time or both) a default under, the certificate of incorporation or bylaws of Amedica, or any material contract, agreement, indenture, loan agreement, receivables purchase agreement, mortgage, deed of trust, or other

- 3 -

agreement or instrument to which Amedica is a party or by which it or any of its properties is bound, (ii) result in the creation or imposition of any lien, adverse claim or other encumbrance upon any of the properties of Amedica pursuant to the terms of any such material contract, agreement, indenture, loan agreement, receivables purchase agreement, mortgage, deed of trust, or other agreement or instrument, or (iii) violate any law or order, rule or regulation applicable to Amedica of any court or of any federal or state regulatory body, administrative agency, or other governmental instrumentality having jurisdiction over Amedica or any of its properties.

(d) This Warrant Agreement and the Warrant each constitutes a legal, valid and binding obligation of Amedica and each is enforceable against Amedica in accordance with the terms hereof and thereof, except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and by general principles of equity (whether considered in a proceeding or action in equity or at law).

(e) Amedica shall at all times keep a sufficient number of authorized but unissued shares of Stock reserved for issuance upon the exercise of the Warrant, and it also shall keep a sufficient number of authorized but unissued shares of Common Stock reserved for issuance upon conversion any Warrant Shares that may be issued resulting from exercise of the Warrant. The Warrant Shares, when issued, delivered and paid for in accordance with the terms of this Warrant Agreement and the Warrant, will be duly and validly issued, fully paid and nonassessable and will not have been issued in violation of the pre-emptive or contractual rights of any person or entity.

(f) Amedica shall deliver to each Holder of ten percent (10%) or more of the aggregate Warrant Shares such information and reports relating to Amedica as Amedica is required to provide to other holders of the Stock. The rights of such Holders under this Section 6(f) shall terminate upon the closing of the IPO.

(g) Upon receipt of evidence reasonably satisfactory to Amedica of the loss, theft, destruction or mutilation of the Warrant or any certificate representing Warrant Shares, and, in the case of any such loss, theft or destruction, upon delivery of indemnity (which may include a bond) reasonably satisfactory to Amedica, or, in the case of any such mutilation, upon surrender and cancellation of the Warrant or any certificate representing Warrant Shares, as the case may be. Amedica will issue a new Warrant or certificates representing Warrant Shares, as the case may be, of like tenor representing an equivalent interest or right, in lieu of such lost, stolen, destroyed or mutilated Warrant or certificates representing Warrant Shares, as the case may be. The applicant for such replacement Warrant shall comply with such other reasonable requests as Amedica may reasonably prescribe.

Section 7. Representations, Warranties and Covenants of Holder. Holder hereby represents, warrants and covenants to Amedica as follows:

(a) Holder is acquiring the Warrant, and upon exercise of the Warrant will acquire the Warrant Shares, for its own account with no intention of distributing or reselling the Warrant or Warrant Shares in any transaction that would be a violation of the securities laws of the United States or any state, without prejudice to the Holder’s rights at all times to sell or otherwise dispose of all or part of such Warrant under a registration under the Securities Act or an exemption available thereto. Holder is aware that neither the Warrant nor the Warrant Shares

- 4 -

are registered under the Securities Act or any state or other jurisdiction’s securities laws, and that Holder must hold the Warrant and the Warrant Shares indefinitely unless subsequently registered or an exemption from registration is available. Holder understands and agrees that the Warrant will bear the restrictive legend set forth on the Warrant and that the Warrant Shares will bear the legend set forth in Section 8 of this Warrant Agreement. Holder represents and warrants that it is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated under the Securities Act.

Section 8. Permitted Transfers and Exchanges. This Warrant Agreement and the Warrant are not transferable and may not be assigned or otherwise transferred by the Holder, other than to Zions affiliates, subsidiaries and its parent company, without the prior written consent of Amedica. Amedica may from time to time register the transfer of the Warrant in a register to be maintained by Amedica upon surrender thereof accompanied by a written instrument or instruments of transfer in the form of assignment attached hereto or as otherwise may be satisfactory to Amedica, duly executed by the Holder thereof or by the duly appointed legal representative thereof or by a duly authorized attorney. Upon any such transfer, the surrendered Warrant shall be canceled and disposed of by Amedica and a new Warrant shall be issued to the transferee(s). The Holder agrees that prior to any proposed transfer of the Warrant or of the Warrant Shares, if such transfer is not made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, the Holder shall deliver to Amedica:

(a) an investment covenant substantially similar to Section 7(a) hereof and otherwise reasonably satisfactory to Amedica signed by the proposed transferee;

(b) an agreement by such transferee to the impression of the restrictive investment legend set forth below on the Warrant or the Warrant Shares;

(c) an agreement by such transferee that Amedica may place a notation in the stock books of Amedica or a “stop transfer order” with any transfer agent or registrar with respect to the Warrant Shares;

(d) an agreement by such transferee to be bound by the provisions of this Section 8 relating to the transfer of such Warrant or Warrant Shares; and

(e) an opinion of counsel, reasonably satisfactory in form and substance to Amedica, that the transfer is exempt from registration requirements under the Securities Act and any applicable state securities laws.

The Holder agrees that each Warrant and each certificate representing Warrant Shares will bear the following legend:

THE SECURITIES EVIDENCED OR CONSTITUTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS THE REGISTRATION PROVISIONS OF SAID ACT AND ANY APPLICABLE STATE SECURITIES LAWS HAVE BEEN COMPLIED WITH OR

A-1

A “Change of Control” shall mean any acquisition of capital stock of the Company, directly or indirectly, any merger, tender offer, recapitalization or asset sale pursuant to which the Company’s stockholders immediately prior to such transaction hold less than 50% of the voting securities of the surviving corporation immediately after such transaction or the majority of the assets of the Company are transferred or sold, except that any internal restructuring or re-organization of the Company that does not change the effective ultimate ownership of the Company shall not be deemed a Change of Control.

This Series E Convertible Preferred Stock Purchase Warrant and all Series E Convertible Preferred Stock Purchase Warrants issued in substitution or exchange therefor are herein individually called a “Warrant” and collectively called “Warrants.”

This Warrant is issued pursuant to and, subject to the terms and conditions of, the Warrant Agreement, which Warrant Agreement is incorporated by reference in and made a part of this instrument. Capitalized terms not otherwise defined herein shall have the meanings given them in the Warrant Agreement. Any conflict between the terms of this Warrant and the Warrant Agreement shall be resolved in favor of the terms of the Warrant Agreement.

This Warrant is further subject to the following provisions, terms and conditions:

1. (a) In order to exercise this Warrant, in whole or in part, the Holder shall deliver to the Company, at the office the Company designated for such purpose in Section 9 of the Warrant Agreement, (i) the form of election to purchase set forth herein properly completed and signed, (ii) payment of the Warrant Price pursuant to Section 1(b), and (iii) this Warrant. Upon receipt of the items referred to in clauses (i), (ii) and (iii) above, the Company shall, as promptly as practicable, and in any event within ten (10) days thereafter, execute or cause to be executed and deliver or cause to be delivered to the Holder a certificate or certificates, in such name or names as the Holder may designate, representing the aggregate number of full shares of Series E Convertible Preferred Stock issuable upon such exercise, together with cash in lieu of any fraction of a share, as hereinafter provided in Section 4 hereof. If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased shares of Series E Convertible Preferred Stock called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(b) Payment to the Company of the purchase price for the Warrant Shares so purchased (the “Warrant Price”) may be made, at the option of the Holder, by payment of the Warrant Price in cash or by wire transfer or cashier’s check drawn on a United States bank.

A-2

(c) Net Exercise. In lieu of exercising this Warrant pursuant to Section 1(b), the Holder may elect to receive, without the payment by the Holder of any additional consideration, shares of Series E Convertible Preferred Stock equal to the value of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with notice of such election, in which event the Company shall issue to the holder hereof a number of shares of Series E Convertible Preferred Stock computed using the following formula:

For purposes of this Section 1(c), the fair market value of one share of Series E Convertible Preferred Stock (or Common Stock, to the extent all such Series E Convertible Preferred Stock has been converted into the Company’s Common Stock) as of a particular date shall be determined as follows: (i) if traded on a securities exchange or through the Nasdaq Global Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the thirty (30) day period ending three (3) days prior to the net exercise election; (ii) if traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the thirty (30) day period ending three (3) days prior to the net exercise; and (iii) if there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the Board of Directors of the Company; provided, however, that, if the Warrant is being exercised upon the closing of an IPO, the value will be the initial “Price to Public” of one share of such Series E Convertible Preferred Stock (or Common Stock issuable upon conversion of such Series E Convertible Preferred Stock) specified in the final prospectus with respect to such offering (net of applicable underwriting commissions).

2. Notwithstanding the foregoing, however, the Company shall not be required to deliver any certificate for shares of Series E Convertible Preferred Stock upon exercise of this Warrant except in accordance with the provisions, and subject to the limitations of, Section 4 hereof and the restrictive legend on the first page hereof.

3. The Company covenants and agrees that the Warrant Shares will, upon issuance, delivery and receipt of consideration therefor, be duly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof. The Company further covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of issue or transfer upon exercise of the subscription rights evidenced by this Warrant, a sufficient number of shares of Warrant Shares to provide for the exercise of the rights represented by this Warrant, and it also will have authorized, and reserved for the purpose of issue, a sufficient number of shares of Common Stock to provide for the

A-3

conversion of Warrant Shares. The Company will take all such action as may be necessary to assure that the Warrant Shares may be so issued without violation of any applicable law or regulation or of any pre-emptive or contractual rights of any person or entity.

4. No fractional shares of Series E Convertible Preferred Stock shall be issued upon the exercise of this Warrant, but, instead of any fraction of a share which would otherwise be issuable, the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the fair market value per share of Series E Convertible Preferred Stock as of the close of business on the date of the notice required by Section 1 above.

5. This Warrant, unless and until exercised, shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.
