Singer (“Stockholder”), and PS Spine HoldCo, LLC, a Delaware limited liability company (the “Member”). Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed to such terms in the Master Transaction Agreement (as defined below).

WHEREAS, concurrently herewith, the Member is entering into a Master Transaction Agreement with Parent, Holdco and Merger Sub (as in effect as of the date hereof, the “Master Transaction Agreement”), providing for, among other things and subject to the terms and conditions of the Master Transaction Agreement, the Merger of Merger Sub with and into Parent, with Parent continuing as the surviving corporation in the Merger, and the Contribution of 100% of the equity interests in the Company by the Member to Holdco.

WHEREAS, as of the date hereof, Stockholder holds and is entitled to vote (or direct the voting of) the Parent Stock set forth opposite Stockholder’s name on Exhibit A hereto (together with such additional Parent Stock that becomes beneficially owned (within the meaning of Rule 13d-3 promulgated under the Exchange Act) by Stockholder, whether upon the exercise of options, conversion of convertible securities or otherwise, after the date hereof, the “Covered Shares”)).

WHEREAS, as a condition to the Member’s willingness to enter into and perform its obligations under the Master Transaction Agreement, the Member has required that Stockholder agree, and Stockholder is willing to agree, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the premises, representations, warranties, covenants and agreements set forth in this Agreement and for other good and valuable consideration given to each party hereto, the receipt of which is hereby acknowledged, the parties agree as follows:

(b)    Any Legal Proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby will be brought and determined exclusively in the Delaware Court of Chancery of the State of Delaware; provided that if the Delaware Court of Chancery does not have subject matter jurisdiction, any such Legal Proceeding will be brought exclusively in the United States District Court for the District of Delaware or any other court of the State of Delaware, and each of the parties hereby consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Legal Proceeding and irrevocably waives, to the fullest extent permitted by Law, any objection that such party may now or hereafter have to the laying of the venue of any such Legal Proceeding in any such court or that any such Legal Proceeding that is brought in any such court has been brought in an inconvenient forum. Process in any such Legal Proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 5.5 will be deemed effective service of process on such party.

EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION WILL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Section 5.7.    Specific Performance.

(a)    The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Each party agrees that in the event of any breach or threatened breach by any other party of any covenant or obligation contained in this Agreement, the non-breaching party shall be entitled (in addition to any other remedy that may be available to such non-breaching party, whether in law or equity, including monetary damages) to (i) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation, and (ii) an injunction restraining such breach or threatened breach.

(b)    Each party further agrees that (x) it will not oppose the granting of an injunction, specific performance or other equitable relief as provided herein on the basis that any other party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity and (y) no other party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 5.7, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Section 5.9.    Headings. Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever.

Section 5.10.    Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the sole extent of such invalidity or unenforceability without rendering invalid or unenforceable the remainder of such term or provision or the remaining terms and provisions of this Agreement in any jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

Section 5.11.    Remedies Cumulative. Except as otherwise provided herein, any and all remedies expressly conferred upon a party hereto shall be deemed cumulative with and not exclusive to any other remedy conferred by this Agreement, or by applicable Law on such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

Section 5.12.    Interpretation.

(a)    When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “or” when used in this Agreement is not exclusive. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such terms.

Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement.

Section 5.13.    Publication. Stockholder hereby permits Parent, Holdco, Merger Sub and the Member to publish and disclose in any documents or schedules required to be filed with the SEC and any other disclosures or filings required by applicable Law Stockholder’s identity and ownership of Stockholder’s Covered Shares and the nature of Stockholder’s commitments pursuant to this Agreement.

Section 5.14.    No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in the Member any direct or indirect ownership or incidence of ownership of or with respect to any Covered Shares. All ownership and economic benefits of and relating to the Covered Shares shall remain vested in and belong to the applicable Stockholder, and, except as otherwise provided herein, the Member shall not have any authority to direct any Stockholder in the voting or disposition of any Covered Shares. For the avoidance of doubt, Stockholder shall be entitled to any dividends or other distributions declared by Parent with respect to Stockholder’s Covered Shares.
