WARRANT AGREEMENT

Exhibit 4.3

THIS WARRANT AGREEMENT, dated as of March 1, 2004 (the “Warrant Agreement”), is by and between CREATION CAPITAL LLC, a Delaware limited liability company (“Creation Capital”), and AMEDICA CORPORATION, a Delaware corporation (the “Company”).

WHEREAS, pursuant to the letter dated July 1, 2003, as amended, Creation Capital was engaged by the Company as the exclusive placement agent to the Company in the United States in connection with the private placement of up to $8.4 million of the Company’s Series A Convertible Preferred Stock (the “Stock”); and

WHEREAS, the July 1, 2003 letter provides that upon each closing of the sale of Stock, Creation Capital shall receive warrants to purchase a number of shares of Stock equal to fifteen percent (15%) of the total number of shares of Stock sold at such closing; and

WHEREAS, the July 1, 2003 letter further provides that the warrants shall be issued pursuant to a definitive warrant agreement mutually agreed to by the Company and Creation Capital.

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 Warrants and the certificates representing the Warrants and the respective rights and obligations thereunder of the Company, Creation Capital and the holders of certificates representing the Warrants, the parties hereto agree as follows:

Section 1. Form of Warrant. The Company shall grant to Creation Capital (Creation Capital and/or its 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 $0.66 per share (the “Exercise Price”) all as more fully set forth herein. The Warrant shall be executed on behalf of the Company by the Chief Executive Officer or any other authorized officer of the Company, 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 the seventh anniversary of the date of issuance of the Warrant (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, $.01 par value per share (the “Common Stock”), of the Company in the Company’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, the Warrant shall, on the date of such event, become immediately exercisable.

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 re-structuring 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.

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 as shall be indicated on the Warrant, 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, 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, the Company shall promptly cause written notice thereof to be sent to the Holder in accordance with Section 13 hereof, which notice shall be accompanied by an officer’s certificate setting forth the number of Warrant Shares purchasable upon the exercise of this 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 the Company 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 the Company;

then, and in any one or more of such cases, the Company shall give written notice thereof to the Holder in accordance with Section 13 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 the Company. The Company hereby represents, warrants and covenants to Holder as follows:

(a) The Company 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. The Company 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 the Company 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 the Company.

(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

-3-

provisions of, or constitute (with or without notice or lapse of time or both) a default under, the certificate of incorporation or bylaws of the Company, or any material contract, agreement, indenture, loan agreement, receivables purchase agreement, mortgage, deed of trust, or other agreement or instrument to which the Company 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 the Company 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 the Company of any court or of any federal or state regulatory body, administrative agency, or other governmental instrumentality having jurisdiction over the Company or any of its properties.

(d) The Warrant Agreement and the Warrant each constitutes a legal, valid and binding obligation of the Company and is enforceable against the Company 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) The Company shall at all times keep a sufficient number of authorized but unissued shares of Stock reserved for issuance upon the 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 non-assessable and will not have been issued in violation of the pre-emptive or contractual rights of any person or entity.

(f) The Company shall deliver to each Holder of ten percent (10%) or more of the aggregate Warrant Shares such information and reports relating to the Company as the Company 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 the Company 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 the Company, 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, the Company 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 the Company may reasonably prescribe.

Section 7. Representations, Warranties and Covenants of Holder. Holder hereby represents, warrants and covenants to the Company 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

-4-

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 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 12 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. Shelf Registration.

(a) As promptly as practicable following the eligibility of the Company or its successor to file a Registration Statement on Form S-3 (or any successor or similar short-form registration statement, a “Shelf Registration Statement”), subject to the limitations herein, the Holder may request, in writing, that the Company file a Shelf Registration Statement with respect to the shares of Common Stock issuable upon conversion of the Warrant Shares (the “Registrable Securities”). In such a notice, the Holder shall advise the Company of the number of Registrable Securities to be included in the Shelf Registration Statement. The Company shall use its best efforts to have such Shelf Registration Statement declared effective by the U.S. Securities and Exchange Commission (“SEC”) as promptly as practicable thereafter. The Company shall use its best efforts to keep any such Shelf Registration Statement continuously effective for the period of at least twenty-four months beginning on the date on which such Shelf Registration Statement is declared effective. The Holder shall provide such information as may be reasonably requested by the Company in connection with the filing of the Shelf Registration Statement or in order to maintain its effectiveness.

(b) Notwithstanding the foregoing, the Company shall not be obligated to file any Shelf Registration Statement pursuant to this Section 8 unless the Registrable Securities to be sold have an anticipated aggregate offering price of at least $1,000,000 (before underwriter’s discounts and commissions). In addition, the Company shall not be obligated to effect any Shelf Registration Statement pursuant to this Section 8 if, in the good faith determination of the Board of Directors, the filing of such registration statement would be detrimental to the Company or its stockholders due to pending material corporate developments or similar material events that have not yet been publicly disclosed and as to which the Company believes that public disclosure would be prejudicial to the Company and may delay such Shelf Registration Statement for a period not in excess of ninety (90) days from such determination. The Company shall be obligated to effect no more than two Shelf Registration Statements during any one calendar year.

(c) The Company shall pay all expenses incurred in connection with a registration pursuant to this Section, including, without limitation, all registration, qualification, printing and accounting fees, all fees and disbursements of counsel for the Company, and all reasonable fees and disbursements of one counsel for the Holders as a group. The Company shall pay all registration fees and other expenses applicable to the Registrable Securities included in the Shelf Registration Statement, provided, that the Holder will be responsible for all underwriting discounts and commissions allocable to the securities sold by such holder.

-5-

Section 9. Piggyback Registration.

(a) If the Company proposes to register any of its equity securities, either for its own account or for the account of any Person, but not including a registration relating to (i) employee stock option or purchase plans, or (ii) a transaction pursuant to Rule 145 under the Securities Act (a “Piggyback Registration”), the Company will:

(i) promptly give written notice thereof to the Holder; and

(ii) use its best efforts to include in such Piggyback Registration and in any underwriting involved therein up to all of the Registrable Securities which the Holder requests in writing to be so included within thirty days after receipt of such written notice from the Company.

The Company shall pay, and shall reimburse the Holder for paying, any expenses incurred in connection with a Piggyback Registration requested pursuant to this Section, including, without limitation, all registration, qualification, printing and accounting fees, all fees and disbursements of counsel for the Company, and all reasonable fees and disbursements of one counsel for the Holders as a group; provided, that the Holder will be responsible for all underwriting discounts and commissions allocable to the securities sold by such holder.

(b) If the registration of which the Company gives notice is for a public offering involving an underwriting, the Company shall so advise the Holder as a part of the written notice given pursuant to this Section, and the right of the Holder to include Registrable Securities in such registration shall be conditioned upon the Holder participation in such underwriting and the entry of the Holder into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company.

(c) If the underwriter of the registered public offering referred to in this Section shall advise the Company in writing that marketing factors require a limitation of the amount of securities to be underwritten, securities shall be included in such offering in the following priority: first, securities to be registered by the Company and/or securities requested to be included pursuant to the exercise of demand registration rights granted by the Company in such priority and proportions as may be agreed among such parties; second, the securities requested to be included in such registration by the Holder pursuant to this Section, the investors who purchased Stock in the offering, and other parties requesting Piggyback Registration rights of the type provided in this Section and having the same priority, pro rata based upon the number of securities requested to be included by such parties; third, the securities requested to be included in such registration by principals of the Company pursuant to the exercise of Piggyback Registration rights of the type provided in this Section, pro rata on the basis of the number of such securities requested to be included by such principal; and fourth, other securities for the account of Persons, including the Holder, allocated among such Persons in accordance with the priorities then existing among the Company and such Persons. Any securities excluded pursuant to the provisions of this Section shall be withdrawn from and shall not be included in such Piggyback Registration.

-6-

(d) Notwithstanding the foregoing, the Company shall not be obligated to effect any Piggyback Registration pursuant to this Section 9 if, in the good faith determination of the Board of Directors, the filing of such registration statement would be detrimental to the Company or its stockholders due to pending material corporate developments or similar material events that have not yet been publicly disclosed and as to which the Company believes that public disclosure would be prejudicial to the Company and may delay such Piggyback Registration Statement for a period not in excess of ninety (90) days from such determination

Section 10. Registration Procedures.

(a) In the case of a registration to be effected by the Company pursuant to this Warrant Agreement in which the Holder is participating, the Company will keep the Holder advised in writing as to the initiation of such registration and as to the completion thereof. In connection with such offering, the Company shall promptly:

(1) prepare and file with the SEC a registration statement with respect to the Registrable Securities and its best efforts to cause such registration statement to become effective for a period of at least 60 days or until the distribution described in the registration statement relating thereto has been completed, whichever shall first occur;

(2) in connection with the preparation and filing of a registration statement, give the Holder, its underwriters, if any, and its counsel, the opportunity (over a reasonable period of time) to review and comment upon any such registration statement, each prospectus included therein or filed with the SEC, and each amendment thereof or supplement thereto, and give each of them access to financial and other records, pertinent corporate documents and properties of the Company and an opportunity to discuss the business of the Company with its officers, its counsel and the independent public accountants who have certified its financial statements as shall be necessary, in the opinion of the Holder and the underwriters’ respective counsel, to conduct a reasonable due diligence investigation within the requirements of the Securities Act;

(3) furnish to the Holder and to the underwriters, if any, of the securities being registered such number of copies of the registration statement, preliminary prospectus, final prospectus and other documents incident thereto as such underwriters and the Holder from time to time may request;

(4) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(5) register or qualify the Registrable Securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be requested by the Holder for the distribution of the Registrable Securities covered by the registration statement to be sold by the Company;

-7-

(6) enter into an underwriting agreement in customary form and substance satisfactory to the Holder and the managing underwriter or underwriters of the public offering of such securities, if the offering is to be underwritten, in whole or in part;

(7) notify the Holder at any time when a prospectus relating thereto covered by such registration statement is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;

(8) cause all such Registrable Securities to be listed on a national securities exchange or on Nasdaq;

(9) unless any Registrable Securities shall be in book-entry form, cooperate with the Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold pursuant to any registration statement free of any restrictive legend and in such permitted denominations and registered in such names as the Holder may request in connection with the sale of Registrable Securities pursuant to such registration statement; and

(10) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to the Holder, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of the Securities Act.

(b) Indemnification.

(1) Indemnification by the Company. The Company will indemnify each Holder requesting or joining in a registration and each underwriter of the securities so registered, the officers, directors and partners of each such person and each person who controls any thereof (within the meaning of the Securities Act) against any and all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of any material fact contained in any prospectus, offering circular or other document incident to any registration, qualification or compliance (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state therein any material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of any rule or regulation promulgated under the Securities Act applicable to the Company and relating to any action or inaction required of the Company in connection with any such registration, qualification or compliance, and the Company will reimburse each such Holder, underwriter, officer, director, partner and controlling person for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such claim, loss, damage or

-8-

liability arises out of or is based on any untrue statement or omission based upon written information furnished to the Company in an instrument duly executed by such Holder, underwriter, officer, director, partner or controlling person and stated to be specifically for use in such prospectus or registration statement.

(2) Indemnification by Each Holder. Each Holder requesting or joining in a registration, will indemnify, severally and not jointly, each underwriter of the securities so registered, the Company and its officers who sign the registration statement and directors and each person, if any, who controls any thereof (within the meaning of the Securities Act) and their respective successors and assigns against any and all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of any material fact contained in any prospectus, offering circular or other document incident to any registration, qualification or compliance (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state therein any material fact required to be stated therein or necessary to make the statements therein not misleading, and such Holder will reimburse each underwriter, the Company and each other person indemnified pursuant to this paragraph for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided, however, that this paragraph shall apply only if (and only to the extent that) such statement or omission was made in reliance upon written information furnished to such underwriter or the Company in an instrument duly executed by such Holder and stated to be specifically for use in such prospectus, offering circular or other document (or related registration statement, notification or the like) or any amendment or supplement thereto; and, provided further, that each Holder’s liability hereunder with respect to any particular registration shall be limited to an amount equal to the net proceeds received by such Holder from the Registrable Securities sold by such Holder in such registration.

(3) Indemnification Proceedings. Each party entitled to indemnification pursuant to this Section 10(b) (the “Indemnified Party”) shall give notice to the party required to provide indemnification pursuant to this Section 10(b) (the “Indemnifying Party”) promptly after such Indemnified Party acquires actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be reasonably acceptable to the Indemnified Party, and the Indemnified Party may participate in such defense at such party’s expense; and provided, further, that the failure by any Indemnified Party to give notice as provided in this paragraph shall not relieve the Indemnifying Party of its obligations under this Section 10(b) except to the extent that the failure results in a failure of actual notice to the Indemnifying Party and such Indemnifying Party is damaged solely as a result of the failure to give notice. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation and no Indemnified Party shall consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party so long as the Indemnifying Party has acknowledged in writing its obligation to indemnify and is in compliance with all of its obligations hereunder to indemnify the Indemnified Party for all amounts in connection with

-9-

such claim or litigation and which consent shall not be unreasonably withheld. If the defendants in any action subject to this Section 10(b) include both the Indemnified Party and the Indemnifying Party and the Indemnified Party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, the Indemnified Party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred.

(c) Contribution in Lieu of Indemnification. If the indemnification provided for in Section 10(b) hereof is unavailable to a party that would have been an Indemnified Party under any such section in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each party that would have been an Indemnifying Party thereunder shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and such Indemnified Party on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Indemnifying Party or such Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and each Holder of Registrable Securities agree that it would not be just and equitable if contribution pursuant to this Section 10(c) were determined by pro-rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 10(c). The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 10(c) shall include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding any provision of this Section 10(c) to the contrary, (a) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation and (b) each Holder’s liability hereunder with respect to any particular registration shall be limited to an amount equal to the net proceeds received by such Holder from the Registrable Securities sold by such Holder in such registration.

Section 11. Effect of Registration Rights of Heirs, Assigns, Beneficiaries, Successors and Transferees. The heirs, assigns, beneficiaries and successor of the Holder shall be entitled to all of the registration rights set forth in Sections 8 through 10 of this Warrant Agreement; provided, however, that such Person or Persons will be able to exercise such rights of the Holder only if it or they have at least 5% of the equity interest in the Company.

Section 12. Transfers and Exchanges. Subject to the terms of Section 15 hereof, the Company shall from time to time register the transfer of the Warrant in a Warrant register to

-10-

be maintained by the Company 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 the Company, 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 the Company 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 the Company:

(a) an investment covenant substantially similar to Section 7(a) and otherwise reasonably satisfactory to the Company 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 the Company may place a notation in the stock books of the Company 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 12 relating to the transfer of such Warrant or Warrant Shares; and

(e) an opinion of counsel, reasonably satisfactory in form and substance to the Company, 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 UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

-11-

Section 14. Counterparts. For the purpose of facilitating the execution of this Warrant Agreement and for other purposes, this Warrant Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed to be an original, and all of which together shall constitute and be one and the same instrument; and such counterparts may be delivered via facsimile to the numbers designated in or pursuant to Section 13.

Section 15. Assignability. Subject to the provisions set forth in Section 12, the Holder may assign the rights and interests under this Warrant Agreement to any person without the Company’s consent; provided, however, that in the event such assignee (other than an assignee which is a Holder Affiliate (as such term is defined below)) is reasonably deemed by the Company to compete with the Company in its traditional business activities (a “competitor”), the Company shall not be required to furnish to such assignee information and reports relating to the Company pursuant to Section 6(f) of this Agreement and, upon notice given by the Company to Holder that such assignee is deemed a “competitor,” Holder shall not furnish to such assignee any information or reports relating to the Company, without the Company’s prior written consent; and provided, further, however, that no such assignment shall be made to the extent such transfer would subject the Company to the reporting requirements of the Securities Exchange Act of 1934, as amended. The Holder shall promptly cause written notice of any such transfer to be sent to the Company in accordance with Section 13 hereof at least fourteen (14) days prior to such transfer. Notwithstanding the foregoing or any other provision to the contrary, the Warrant and the Warrant Shares will be “restricted securities” as defined in Rule 144 under the Securities Act, and thus will not be transferable except in compliance with applicable federal and state securities laws and regulations. “Holder Affiliate” shall mean any person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such Holder.

Section 16. Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) Governing Law. This Warrant Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to conflict of law principles.

(b) Jurisdiction. Each of the Company and the Holder hereby irrevocably submits to the jurisdiction of any New York State or Federal court sitting in New York City in any action or proceeding arising out of or relating to this Warrant Agreement or the Warrant, and each of the Company and the Holder hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such New York State court or in such Federal court. Each of the Company and the Holder hereby irrevocably waives, to the fullest extent permitted under applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding. Each of the Company and the Holder irrevocably consents, to the fullest extent permitted under applicable law, to the service of any summons and complaint and any other process by the mailing of copies of such process to them at their respective address specified in Section 13. Each of the Company and the Holder hereby agrees, to the fullest extent permitted under applicable law, that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

-13-

(c) Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED UNDER APPLICABLE LAW, EACH OF THE COMPANY AND THE HOLDER HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS WARRANT AGREEMENT OR ANY WARRANT ISSUED HEREUNDER.

Section 17. Amendments. This Warrant Agreement may be amended from time to time by written instrument signed by the Company and the Holders of a majority of the Warrant Shares issued or issuable upon exercise of the Warrant and no waiver of any of the terms hereof shall be effective unless it is in writing and signed by the Holders of a majority of the Warrant Shares issued or issuable upon exercise of the Warrant or the Company, as the case may be. Any amendment or waiver pursuant to this Section 17 shall be binding on all Holders of the Warrant Shares and may be given retroactive, prospective or concurrent effect, depending upon the language in such amendment or waiver.

Section 18. No Waiver. No failure on the part of the Holder or the Company to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

Section 19. Termination. This Warrant Agreement shall terminate on the Warrant Termination Date. Notwithstanding the foregoing, this Warrant Agreement will terminate on any earlier date if the Warrant has been exercised in full.

WARRANT TO PURCHASE SERIES A CONVERTIBLE PREFERRED STOCK

To Subscribe for and Purchase Series A Convertible Preferred Stock

AMEDICA CORPORATION

WARRANT NO.

This certifies that, for value received, Creation Capital LLC, a Delaware limited liability company (“Creation Capital”), or its assigns (Creation Capital and/or its assigns are collectively referred to herein as the “Holder”), is entitled to subscribe for and purchase from Amedica Corporation, a Delaware corporation (the “Company”), at any time commencing on the first anniversary of the date hereof and shall terminate at 5:00 p.m., New York City Time, on the seventh anniversary of the date hereof (the “Warrant Termination Date”), shares (the “Warrant Shares”) of the Company’s Series A Convertible Preferred Stock, par value $.01 per share (the “Series A Preferred Stock”), subject to adjustment as provided in that certain Warrant Agreement, dated as of March 1, 2004, by and between the Company and Creation Capital (the “Warrant Agreement”), at an exercise price of $0.66 per share, as such exercise price may be adjusted from time to time under the Warrant Agreement. No Warrant may be exercised after the Warrant Termination Date.

A-1

In the event of (a) the closing of the issuance and sale of shares of common stock, $.01 par value per share (the “Common Stock”), of the Company in the Company’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, the Warrant shall, on the date of such event, become immediately exercisable.

This Series A Preferred Stock Purchase Warrant and all Series A 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 13 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 A Preferred Stock issuable upon such exercise, together with cash in lieu of any fraction of a share, as hereinafter provided in Section 4. 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 A 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.

(c) Net Exercise. In the event of any exercise of this Warrant in connection with a mandatory conversion of the Series A Preferred Stock into shares of the Company’s

A-2

Common Stock pursuant to Section 2(c) of the Certificate of Designation, Preferences and Rights of the Series A Convertible Preferred Stock, 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 A 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 A Preferred Stock computed using the following formula:

X = Y × (A-B)


Where:	X =	The number of shares of Series A Preferred Stock to be issued to the Holder pursuant to this net exercise;

	Y =	The number of shares of Series A Preferred Stock in respect of which the net issue election is made;

	A =	The fair market value of one share of the Series A Preferred Stock at the time the net issue election is made;

	B =	The Exercise Price (as adjusted to the date of the net issuance).

For purposes of this Section 1(c), the fair market value of one share of Series A Preferred Stock (or Common Stock, to the extent all such Series A 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 National 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 the IPO, the value will be the initial “Price to Public” of one share of such Series A Preferred Stock (or Common Stock issuable upon conversion of such Series A 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 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

A-3

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. 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 A 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 A 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.

6. Subject to the provisions of Section 12 and Section 15 of the Warrant Agreement, this Warrant and all rights hereunder are assignable.
