held by the Guarantee Trustee for the benefit of the Holders, and the Guarantee Trustee shall not transfer this Guarantee Agreement to any Person except to a Successor Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its
appointment to act as Guarantee Trustee hereunder. The right, title and interest of the Guarantee Trustee, as such, hereunder shall automatically vest in any Successor Guarantee Trustee, upon acceptance by such Successor Guarantee Trustee of its
appointment hereunder, and such vesting of title shall be effective whether or not conveyancing documents have been executed and delivered pursuant to the appointment of such Successor Guarantee Trustee. 
 (b) If an Event of Default has occurred and is continuing of which the Guarantee Trustee is deemed to have knowledge pursuant to Section 2.7(b)
hereof, the Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the Holders. 
 (c) The Guarantee Trustee, before the
occurrence of any Event of Default, and after the curing of all Events of Default that may have occurred, shall undertake to perform only such duties as are specifically set forth in this Guarantee Agreement, and no implied covenants shall be read
into this Guarantee Agreement against the Guarantee Trustee. The Guarantee Trustee shall, during the existence of any Event of Default of which the Guarantee Trustee is deemed to have knowledge pursuant to Section 2.7(b) hereof and which has
not been cured or waived pursuant to Section 2.6, exercise such of the rights and powers vested in it by this Guarantee Agreement, and use the same degree of care and skill in its exercise thereof, as a prudent person would exercise or use
under the circumstances in the conduct of his or her own affairs. 
 (d) No provision of this Guarantee Agreement shall be construed to
relieve the Guarantee Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (i) Prior to the occurrence of any Event of Default and after the curing or waiving of all such Events of Default that may have occurred: 
 (A) the duties and obligations of the Guarantee Trustee shall be determined solely by the express provisions of this Guarantee Agreement
(including pursuant to Section 2.1), and the Guarantee Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Guarantee Agreement; and 
 (B) in the absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Guarantee Trustee and conforming to the requirements of this Guarantee Agreement; but in the case of any such certificates or
opinions that by any provision hereof or of the Trust Indenture Act are specifically 

  

 5 

 
required to be furnished to the Guarantee Trustee, the Guarantee Trustee shall be under a duty to examine the same to determine whether or not they conform
to the requirements of this Guarantee Agreement. 
 (ii) The Guarantee Trustee shall not be liable for any error of judgment
made in good faith by an officer of the Guarantee Trustee, unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent facts upon which such judgment was made. 
 (iii) The Guarantee Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance
with the direction of the Holders of not less than a Majority in Liquidation Amount of the Preferred Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee, or exercising any
trust or power conferred upon the Guarantee Trustee under this Guarantee Agreement. 
 (iv) No provision of this Guarantee
Agreement shall require the Guarantee Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if the Guarantee Trustee shall
have reasonable grounds for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Guarantee Agreement or adequate indemnity against such risk or liability is not reasonably assured to it.

 Section 3.2 Certain Rights of Guarantee Trustee. 
 (a) Subject to the provisions of Section 3.1: 
 (i) The Guarantee Trustee may rely and
shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper
or document reasonably believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. 
 (ii) Any direction or act of the Guarantor contemplated by this Guarantee Agreement shall be sufficiently evidenced by an Officers’ Certificate unless otherwise prescribed herein. 
 (iii) Whenever, in the administration of this Guarantee Agreement, the Guarantee Trustee shall deem it desirable that a matter be proved
or established before taking, suffering or omitting to take any action hereunder, the Guarantee Trustee (unless other evidence is herein specifically prescribed) may, in the absence of bad faith on its part, request and rely upon an Officers’
Certificate which, upon receipt of such request from the Guarantee Trustee, shall be promptly delivered by the Guarantor. 
 (iv) The Guarantee Trustee may consult with legal counsel, and the written advice or opinion of such legal counsel with respect to legal matters shall be full and complete authorization and protection in respect of any action taken,
suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or opinion. Such legal counsel may be legal counsel to the Guarantor or any of its Affiliates and may be one of its employees. The Guarantee Trustee
shall have the right at any time to seek instructions concerning the administration of this Guarantee Agreement from any court of competent jurisdiction. 
 (v) The Guarantee Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Guarantee Agreement at the request or direction of any Holder unless such Holder shall have provided
to the Guarantee Trustee such adequate security and indemnity as would satisfy a reasonable person in the position of the Guarantee Trustee against the costs, expenses (including attorneys’ fees and expenses) and liabilities that might be
incurred by it in complying with such request or direction, including such reasonable advances as may be requested by the Guarantee Trustee; provided that nothing contained in this Section 3.2(a)(v) shall be taken to relieve the Guarantee
Trustee, upon the occurrence of an Event of Default, of its obligation to exercise the rights and powers vested in it by this Guarantee Agreement. 
  

 6 

 (vi) The Guarantee Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Guarantee Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see fit. 
 (vii) The
Guarantee Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, and the Guarantee Trustee shall not be responsible for any misconduct or negligence on the
part of any such agent or attorney appointed by it with due care hereunder. 
 (viii) Whenever in the administration of this
Guarantee Agreement the Guarantee Trustee shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder, the Guarantee Trustee (A) may request instructions from the Holders,
(B) may refrain from enforcing such remedy or right or taking such other action until such instructions are received, and (C) shall be protected in acting in accordance with such instructions. 
 (b) No provision of this Guarantee Agreement shall be deemed to impose any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Guarantee Trustee shall be unqualified or incompetent in accordance with applicable law, to perform any such
act or acts or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Guarantee Trustee shall be construed to be a duty to act in accordance with such power and authority. 
 Section 3.3 Compensation; Indemnity; Fees. 
 The Guarantor agrees: 
 (a) to pay to the Guarantee Trustee from time to time such reasonable compensation
for all services rendered by it hereunder as may be agreed by the Guarantor and the Guarantee Trustee from time to time (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

 (b) except as otherwise expressly provided herein, to reimburse the Guarantee Trustee upon request for all reasonable expenses,
disbursements and advances incurred or made by the Guarantee Trustee in accordance with any provision of this Guarantee Agreement (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or willful misconduct; and 
 (c) to indemnify the Guarantee
Trustee and its directors, officers, employees and agents (collectively with the Guarantee Trustee, the “Indemnitees”) for, and to hold them harmless against, any loss, liability or expense, including without limitation, damages,
fines, suits, actions, demands, penalties, costs, out-of-pocket or incidental expenses, reasonable legal fees and expenses and the costs and expenses of defending itself against any claim in connection with the exercise or performance of any of its
powers or duties hereunder (collectively, “Losses”), that may be imposed on or incurred by any Indemnitee for or in respect of the Guarantee Trustee’s (i) execution and delivery of this Guarantee Agreement,
(ii) compliance or attempted compliance with or reliance upon any instruction or other direction upon which the Guarantee Trustee is authorized to rely pursuant to the terms of this Guarantee Agreement and (iii) performance under this
Guarantee Agreement, except in each case to the extent that the Loss resulted from the Guarantee Trustee’s or such Indemnitee’s negligence, willful misconduct or bad faith. The provisions of this Section shall survive the termination of
this Guarantee Agreement and the resignation or removal of the Guarantee Trustee for any reason. The Guarantee Trustee will not claim or exact any lien or charge on any Guarantee Payments as a result of any amount due to it under this Guarantee

subsequent accounting) by giving written notice thereof to the Holders and the Guarantor and by appointing a successor Guarantee Trustee. The Guarantee Trustee shall appoint a successor by requesting from at least three Persons meeting the
requirements of Section 4.1(a) their expenses and charges to serve as the Guarantee Trustee, and selecting the Person who agrees to the lowest expenses and charges. 
 (c) The Guarantee Trustee appointed hereunder shall hold office until a Successor Guarantee Trustee shall have been appointed and shall have accepted such appointment. No removal or resignation of a Guarantee Trustee
shall be effective until a Successor Guarantee Trustee has been appointed and has accepted such appointment by written instrument executed by such Successor Guarantee Trustee and delivered to the Guarantor and, in the case of any resignation, the
resigning Guarantee Trustee. 
 (d) If no Successor Guarantee Trustee shall have been appointed and accepted appointment as provided in this
Section 4.2 within 60 days after delivery to the Holders and the Guarantor of a notice of resignation, the resigning Guarantee Trustee may petition, at the expense of the Guarantor, any court of competent jurisdiction for appointment of a
Successor Guarantee Trustee. Such court may thereupon, after prescribing such notice, if any, as it may deem proper, appoint a Successor Guarantee Trustee. 
 (e) If a resigning Guarantee Trustee shall fail to appoint a successor, or if a Guarantee Trustee shall be removed or become incapable of acting as Guarantee Trustee and a replacement shall not be appointed prior to
such resignation or removal, or if a vacancy shall occur in the office of Guarantee Trustee for any cause, the Holders of the Preferred Securities, by the action of the Holders of record of not less than 25% in aggregate Liquidation Amount (as
defined in the Trust Agreement) of the Preferred Securities then Outstanding (as 

  

 8 

 
defined in the Trust Agreement) delivered to such Guarantee Trustee, may appoint a Successor Guarantee Trustee or Trustees. If no successor Guarantee Trustee
shall have been so appointed by the Holders of the Preferred Securities and accepted appointment, any Holder, on behalf of such Holder and all others similarly situated, or any other Guarantee Trustee, may petition any court of competent
jurisdiction for the appointment of a successor Guarantee Trustee.

	Company:	  	ALPHATEC HOLDINGS, INC., a Delaware corporation
	Number of Shares:	  	190,476
	Class of Stock:	  	Common
	Warrant Price:	  	$1.89 per share
	Issue Date:	  	December 5, 2008
	Expiration Date:	  	The 10th anniversary after the Issue Date
	Credit Facility:	  	This Warrant is issued in connection with the Loan and Security Agreement between Company, Alphatec Spine, Inc. and Silicon Valley Bank and Oxford Finance Corporation dated as of December 5,
2008, as amended from time to time (the “Loan Agreement”).

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, including without limitation the
mutual promises contained in the Loan Agreement SILICON VALLEY BANK (Silicon Valley Bank, together with any registered holder from time to time of this Warrant or any holder of the shares issuable or issued upon exercise of this Warrant,
“Holder”) is entitled to purchase the number of fully paid and nonassessable shares of the class of securities (the “Shares”) of the Company at the Warrant Price, all as set forth above and as adjusted pursuant to Article 2
of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. 
 ARTICLE 1. EXERCISE. 
 1.1 Method of Exercise. Holder may exercise this Warrant by delivering a duly executed Notice of Exercise in substantially the form attached as
Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion right set forth in Article 1.2, Holder shall also deliver to the Company a check, wire transfer (to an account designated by the Company), or other form of
payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased. 
 1.2 Conversion Right. In lieu of
exercising this Warrant as specified in Article 1.1, Holder may from time to time convert this Warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares or other securities
otherwise issuable upon exercise of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to Article 1.3. 
 1.3 Fair Market Value. If the Company’s common stock is traded in a public market, the fair market value of each Share shall be the closing
price of a Share reported for the business day immediately before Holder delivers its Notice of Exercise to the Company. If the Company’s common stock is not traded in a public market, the Board of Directors of the Company shall determine fair
market value in its reasonable good faith judgment. 

 1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this
Warrant and, if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a
new Warrant representing the Shares not so acquired. 
 1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation
on surrender and cancellation of this Warrant, the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 
 1.6 Treatment of Warrant Upon Acquisition of Company. 
 1.6.1 “Acquisition”. For the purpose
of this Warrant, “Acquisition” means any sale, license, or other disposition of all or substantially all of the assets of the Company, or any reorganization, consolidation, or merger of the Company where the holders of the Company’s
securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction. 
 1.6.2 Treatment of Warrant at Acquisition. 
 A) Upon the written request of the Company, Holder agrees that, in the
event of an Acquisition that is not an asset sale and in which the sole consideration is cash, either (a) Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to
the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide the Holder with written notice of its request relating to
the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing
of the proposed Acquisition. 
 B) Upon the written request of the Company, Holder agrees that, in the event of an Acquisition that is an “arms
length” sale of all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined below) of the Company (a “True Asset Sale”), either (a) Holder shall exercise its
conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will continue until the
Expiration Date if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the Holder with written notice of its request relating to the foregoing (together with such reasonable
information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition. 

 C) Upon the closing of any Acquisition other than those particularly described in subsections (A) and
(B) above, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be payable for the Shares issuable upon exercise of the unexercised portion
of this Warrant as if such Shares were outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price and/or number of Shares shall be adjusted accordingly. 
 As used herein “Affiliate” shall mean any person or entity that owns or controls directly or indirectly ten (10) percent or more of the stock of Company, any person or entity that controls or is
controlled by or is under common control with such persons or entities, and each of such person’s or entity’s officers, directors, joint venturers or partners, as applicable. 
 ARTICLE 2. ADJUSTMENTS TO THE SHARES. 
 2.1 Stock Dividends, Splits, Etc. If the Company
declares or pays a dividend on the Shares payable in common stock, or other securities, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities to which
Holder would have been entitled had Holder owned the Shares of record as of the date the dividend occurred. If the Company subdivides the Shares by reclassification or otherwise into a greater number of shares or takes any other action which
increase the amount of stock into which the Shares are convertible, the number of shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares are combined or
consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased. 
 2.2 No Impairment. The Company shall not, by amendment of its Articles or Certificate (as applicable) of Incorporation or through a
reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this
Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Article 2 and in taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article against
impairment. 
 2.3 Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of this Warrant and the
number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the Warrant, the Company shall eliminate such fractional share interest by paying Holder the
amount computed by multiplying the fractional interest by the fair market value of a full Share. 
 2.4 Certificate as to Adjustments.
Upon each adjustment of the Warrant Price, the Company shall promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such
Warrant Price. 
 ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY. 
 3.1 Representations and Warranties. The Company represents and warrants and covenants to the Holder as follows: 
 (a) The initial Warrant Price referenced on the first page of this Warrant is not greater than (i) the price per share at which the
Shares were last issued in an arms-length transaction in which at least $500,000 of the Shares were sold and (ii) the fair market value of the Shares as of the date of this Warrant. 

 (b) All Shares which may be issued upon the exercise of the purchase right represented by
this Warrant, and all securities, if any, issuable upon conversion of the Shares, shall, upon issuance, be duly authorized, validly issued, fully paid and nonassessable, and free of any liens and encumbrances except for restrictions on transfer
provided for herein or under applicable federal and state securities laws. 
 3.2 Notice of Certain Events. If the Company proposes at
any time (a) to declare any dividend or distribution upon any of its stock, whether in cash, property, stock, or other securities and whether or not a regular cash dividend; (b) to offer for sale any shares of the Company’s capital
stock (or other securities convertible into such capital stock), other than (i) pursuant to the Company’s stock option or other compensatory plans, (ii) in connection with commercial credit arrangements or equipment financings, or
(iii) in connection with strategic transactions for purposes other than capital raising; (c) to effect any reclassification or recapitalization of any of its stock; (d) to merge or consolidate with or into any other corporation, or
sell, lease, license, or convey all or substantially all of its assets, or to liquidate, dissolve or wind up; or (e) offer holders of registration rights the opportunity to participate in an underwritten public offering of the Company’s
securities for cash, then, in connection with each such event, the Company shall give Holder: (1) at least 10 days prior written notice of the date on which a record will be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of common stock will be entitled thereto) or for determining rights to vote, if any, in respect of the matters referred to in (a) and (b) above; (2) in the case of the matters referred to in
(c) and (d) above at least 10 days prior written notice of the date when the same will take place (and specifying the date on which the holders of common stock will be entitled to exchange their common stock for securities or other

“Piggyback,” registration rights pursuant to and as set forth in the Company’s Stockholders’ Agreement or similar agreement. The provisions set forth in the Company’s Stockholders’ Agreement or similar agreement
relating to the above in effect as of the Issue Date may not be amended, modified or waived without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated with the Shares in the same manner as
such amendment, modification, or waiver affects the rights associated with all other shares of the same series and class as the Shares granted to the Holder. 
 3.4 No Shareholder Rights. Except as provided in this Warrant, the Holder will not have any rights as a shareholder of the Company until the exercise of this Warrant.

acquiring this Warrant or the Shares.
