Annex A

Alphatec SEVERANCE agreement

INTRODUCTION

This Severance Agreement (the “Agreement”) is entered into as of December 10, 2016 by and between Alphatec Holdings, Inc. (the “Company”) and Xxxxx X. Xxxx (the “Executive”) to provide severance benefits to the Executive in the event his employment is terminated involuntarily under certain circumstances. All benefit determinations under this Severance Agreement and any interpretation of provisions in this Severance Agreement will be made by the Board of Directors of the Company (the “Board”) or its designee in its reasonable, good faith sole discretion. The Agreement is described in further detail below.

II.

ELIGIBILITY

In the event Executive is terminated involuntarily he will be eligible for severance benefits described in Section III of this Agreement, PROVIDED each of the following requirements is met:

The termination of employment is involuntary.

The termination is not due to retirement, death or disability of the Executive.

The termination of employment is not for “cause” (as defined below). For purposes of the Agreement, “cause” shall mean the following:

1.Executive’s repeated failure to satisfactorily perform executive’s job duties;

2.refusal or failure to follow the lawful and reasonable directions of the Board, as applicable;

3.conviction of, or plea of guilty or nolo contendere to a felony; or

4.engaging in acts or omissions constituting gross negligence, recklessness or willful misconduct on the part of the Executive with respect to his/her obligations to the Company or otherwise relating to the business of the Company, its affiliates or customers.

The Executive must be provided a period of at least thirty (30) days following receipt of written notice outlining with specificity all acts or omissions that the Company alleges give rise to a termination for cause pursuant to Section II, C.1 or C.2 immediately above, during which period he may effect a cure of any curable actions or omissions forming the basis for the termination for cause. The Board, will, in its sole discretion, exercised reasonably and in good faith, apply the definitions of “cause” herein to determine if a termination of employment is for “cause”.

The Executive is not a temporary employee or a new hire who has not yet started to work on a regular, full-time or part-time basis (as appropriate).

The Executive is not covered under any other severance-type plan, policy, arrangement or agreement that provides severance payments and benefits more favorable in the aggregate to those provided herein. If any such plan, policy, arrangement or agreement exists, the Executive will receive payments and benefits pursuant to that plan, policy, arrangement or agreement and shall not receive any of the severance payments and benefits described herein. In no case will the Executive receive severance payments and benefits under any other such severance-type plan, policy, arrangement or agreement and this Agreement.

In the event that the Executive is party to a “Change in Control” Agreement with Company that also provides for severance benefits, in the event of a “Change in Control” (as defined therein) the Executive shall not receive benefits under this Agreement, but instead shall receive only the severance benefits provided under such “Change in Control” Agreement (i.e., there shall be no “double-dipping” and only the “Change in Control” Agreement shall apply in such an event).

The Executive has not agreed in writing to waive severance benefits under this Agreement or otherwise payable from the Company.

The Executive (or, in the event of the executive’s death or incapacity, the Executive’s executor, representative or guardian, as applicable) signs and does not revoke a separation agreement and general release of all claims in such form as the Company may from time-to-time reasonably require (“Separation Agreement”).

The Executive has returned all Company property and equipment that was assigned to, or taken general control of by, her or him during his tenure with the Company.

If terminated, the Executive must satisfy all of the requirements set forth above in order to receive severance benefits under this Agreement. If the Executive satisfies all of the eligibility conditions described above, the Executive will receive severance benefits calculated in accordance with Section III below. The severance benefits will be paid following the Executive’s termination of employment in accordance with the terms set forth below and in the respective Separation Agreement.

III.

SEVERANCE BENEFITS

Xxxxxxxxx Pay and Benefits. The following severance pay and benefits are payable under this Agreement:

1.Severance Pay. The severance pay provided to the Executive if involuntarily terminated under the terms of this Agreement consists of an amount equal to the sum of (i) one and one-half times (1.5x) the sum of (x) his regular annual base salary and (y) his annual target bonus in effect for the calendar year in which the termination of employment occurs.

The amount of severance pay to the Executive shall be based upon the Executive’s regular annual base salary in effect immediately before the Executive’s termination of employment, determined without regard to any overtime, bonuses, fringe benefits, reimbursements or other irregular payments. The Executive’s general release of all claims referred to in Section II.H. must be effective the sixtieth (60^th) day following the Executive’s termination of employment in order for the Executive to receive any severance pay or benefits under the Agreement. Severance pay will be paid in a single cash lump-sum on the sixtieth (60^th) day following the Executive’s termination of employment (or as soon as administratively practicable after such sixtieth (60^th) day).

2.Benefits Continuation. Upon an involuntary termination of employment pursuant to which the Executive is entitled to severance pay under Section III.A.1., subject to the Executive’s timely election of continuation coverage under the Consolidated Budget Omnibus Reconciliation Act of 1985, as amended (“COBRA”), the Company will pay the premiums for the Executive for a period of eighteen (18) months based on the level of coverage in effect as of the date of the Executive’s termination. Notwithstanding the foregoing, in the event that the Executive becomes eligible to receive substantially similar or improved medical, dental or vision benefits from a subsequent employer (whether or not the Executive accepts such benefits), the Company’s obligations under this Section III.A.2. shall immediately cease. The Executive will notify the Company of his eligibility for such benefits from a subsequent employer within thirty (30) days of such eligibility.

In the event that the Company’s making payments under this Section III.A.2 would violate nondiscrimination rules or result in the imposition of penalties under the Patient Protection and Affordable Care Act of 2010 (“PPACA”) and related regulations and guidance promulgated thereunder, the parties agree to reform this Section III.A.2. in such manner as is necessary to comply with tax laws and the PPACA, as applicable.

3.Equity Awards. Upon an involuntary termination of employment pursuant to which the Executive is entitled to severance pay under Section III.A.1., any vested stock option awards held by Executive at the time of his termination will remain exercisable by the Executive for the greater of (i) 90 days following the effective date of the Executive’s termination and (ii) the remaining term of such option award, and all other Company equity awards held by Executive that remain unvested upon the effective date of his termination will be forfeited for no consideration.

If Executive is not a Specified Employee, all payments made to Executive under Section 3(a) immediately above shall be made on the sixtieth (60^th) calendar day following Executive’s Separation from Service, provided that Executive’s Release must be effective and not revocable on the date payment is to be made in order to receive such payments. If Executive is a Specified Employee, to the extent required to comply with Section 409A of the Code, payments made under Section 3(a) immediately above shall be made within ten (10) calendar days following the date following the first (1^st) day of the seventh (7^th) month after the date of Executive’s Separation from Service, provided that no such payment shall be made to Executive if the Release has not become effective as of the six (6)-month anniversary of the date of Executive’s Separation from Service.

Parachute Payments. In the event that any of the severance payments and other benefits provided by this Agreement or otherwise payable to Executive (a) constitute “parachute payments” within the meaning of Section 280G of the Code, and (b) but for this Section, would be subject to the excise tax imposed by Section 4999 of the Code (“Excise Tax”), then Executive’s severance payments and benefits under this Agreement or otherwise shall be payable either in full or in such lesser amount which would result in no portion of such severance payments or benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income and employment taxes and the Excise Tax, results in the receipt by Executive, on an after-tax basis, of the greatest amount of severance payments and benefits under this Agreement or otherwise, notwithstanding that all or some portion of such severance payments or benefits may be taxable under Section 4999 of the Code. Any reduction in the severance payments and benefits required by this Section shall be made in the following order: (i) reduction of cash payments; (ii) reduction of accelerated vesting of equity awards other than stock options; (iii) reduction of accelerated vesting of stock options; and (iv) reduction of other benefits paid or provided to Executive. The calculations in Section 4 will be performed by the professional firm engaged by the Company for general tax purposes as of the day prior to the date of the event that might reasonably be anticipated to result in severance payments and benefits that would otherwise be subject to the Excise Tax. If the tax firm so engaged by the Company is serving as accountant or auditor for the acquiring company, the Company shall appoint a nationally recognized tax firm to make the determinations required by this Section. The Company shall bear all expenses with respect to the determinations by such firm required to be made by this Section 4. The Company and Executive shall furnish such tax firm such information and documents as the tax firm may reasonably request in order to make its required determination. The tax firm will provide its calculations, together with detailed supporting documentation, to the Company and Executive as soon as practicable following its engagement. Any good faith determinations of the tax firm made hereunder shall be final, binding and conclusive upon the Company and Executive. As a result of the uncertainty in the application of Sections 409A, 280G or 4999 of the Code at the time of the initial determination by the professional tax firm described in this Section 4, it is possible that the Internal Revenue Service (the “IRS”) or other agency will claim that an Excise Tax greater than that amount, if any, determined by such professional firm for the purposes of Section 4 is due (the “Additional Excise Tax”). Executive shall notify the Company in writing of any claim by the IRS or other agency that, if successful, would require payment of Additional Excise Tax. Executive and the Company shall each reasonably cooperate with the other in connection with any administrative or judicial proceedings concerning the existence or amount of liability for Excise Tax with respect to payments made or due to Executive. The Company shall pay all reasonable fees, expenses and penalties of Executive relating to a claim by the IRS or other agency. In the event it is finally determined that a further reduction would have been required under Section 4 to place Executive in a better after-tax position, Executive shall repay the Company such amount within 30 days thereof in order to effect such result.

No Mitigation. Executive shall not be required to mitigate the amount of any payment or benefit provided for in Section 3 hereof by seeking other employment or otherwise, nor shall the amount of such payment be reduced by reason of compensation or other income Executive receives for services rendered after Executive’s Separation from Service from the Company.

Exclusive Remedy. In the event of Executive’s Separation from Service on account of an involuntary termination without Cause or a voluntary termination for Good Reason within twenty-four (24) months following a Change in Control, the provisions of Section 3 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive or the Company may otherwise be entitled (including any contrary provisions in

any employment agreement Executive may have with the Company), whether at law, tort or contract, in equity, or under this Agreement. Payments made to or on behalf of Executive under any other severance plan, policy, contract or arrangement with the Company shall reduce amounts payable under this Agreement on a dollar for dollar basis.

Company’s Successors. The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, to expressly assume and agree to perform the obligations under this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. As used in this Section 7, Company includes any successor to its business or assets as aforesaid which executes and delivers this Agreement or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

Notice. Notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when personally delivered or five (5) days after deposit with postal authorities transmitted by United States registered or certified mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth on the first or last page of this Agreement, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

Amendment or Waiver. No provisions of this Agreement may be amended, modified, waived or discharged unless Executive and the Company agree to such amendment, modification, waiver or discharge in writing. No amendment, modification, waiver or discharge of this Agreement shall result in the accelerated payment of any benefit or payment provided for in Section 3. No waiver by either party at any time of the breach of, or lack of compliance with, any conditions or provisions of this Agreement shall be deemed a waiver of the provisions or conditions hereof.
