For good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1.Termination of Employment. The parties agree that Executive's employment with the Company and all of its affiliates is terminated effective as of December 1, 2015 (the "Termination Date"). For the purposes of calculating any benefits due to Executive under this Agreement, the parties agree that Executive's termination constitutes a resignation by Executive "For Good Reason" and pursuant to a "Change in Control" as those terms are defined in Amended and Restated Employment Agreement dated October 9, 2014, as amended by Amendment to Employment Agreement dated June 2, 2015 by and between the Company and Executive (the "Employment Agreement").

2.Payments Due to Executive. Not later than the Company's next regularly scheduled payday after the Termination Date, the Company will pay Executive: (a) his accrued but unpaid Base Salary through the Termination Date, and (b) $18,846.10, which is the Executive's amount of accrued and unused vacation as of the date hereof. Other than as expressly set forth in this Section, Executive is not entitled to any consulting fees, wages (other than Executive's 2015 management incentive plan incentive award and the special cash payment of $1 million payable upon the Termination Date as approved by the compensation committee of the Board of Directors on November 19, 2015), accrued vacation pay, benefits or any other amounts with respect to his employment through the Termination Date.

3.Accelerated Vesting. Pursuant to Section 3.4(a)(iii) of the Employment Agreement, the Company will accelerate the vesting of all of Executive's outstanding and unvested stock options, stock appreciation rights, restricted stock units or shares, performance stock units or any other equity compensation award previously made to Executive.

4.Business Expenses. The Company agrees to reimburse Executive for reasonable business expenses incurred prior to the date hereof provided the expenses (a) were incurred in accordance with the Company's normal policies and practices and (b) are submitted no later than December 31, 2015.

5.Severance Benefits and Continuing Health Insurance Coverage. In consideration of Executive's execution and non-revocation of this Agreement, the Company agrees as follows:

(a)The Company shall pay Executive $4,350,000, which pursuant to Section 3.4(a)(i) of the Employment Agreement is an amount equal to the product of (i) 3.0 and (ii) the sum of (x) the highest annual Base Salary rate for Executive in effect over the prior two (2) years and (y) the highest amount of Executive's Target Bonus or Annual Cash Bonus actually paid over the prior two

(2) years, whichever is greater, which total payment shall be paid to Executive on a salary continuation basis according to the Company's normal payroll practices over the 18 month period following the Termination Date, but in no event less frequently than monthly.

(b)For so long as Executive serves as a member of the board of directors of the Company following the Termination Date, and subject to Executive's continued copayment of premiums at the same level and cost to the Executive as if the Executive were an employee of the Company (excluding, for purposes of calculating cost, an employee's ability to pay premiums with pre-tax dollars), the Company shall provide participation in the Company's group health plan and ArmadaCare executive health reimbursement plan (the "ArmadaCare Plan") in each case to the extent permitted by applicable law and the terms of such plan. Upon termination of Executive's service as a director of the Company, and subject to (i) Executive's timely election of continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), and (ii) Executive's continued copayment of premiums at the same level and cost to the Executive as if the Executive were an employee of the Company (excluding, for purposes of calculating cost, an employee's ability to pay premiums with pre-tax dollars), the Company shall provide continued participation in the Company's group health plan (to the extent permitted under applicable law and the terms of such plan) which covers the Executive (and the Executive's eligible dependents) for a period of 18 months (collectively, the "COBRA Benefits"), provided that the Executive is eligible and remains eligible for COBRA coverage. The Company shall pay or reimburse Executive for the incremental cost of Executive's participation in the Company's group health plan and ArmadaCare Plan as described in this Section 5(b) (over and above the customary employee copayment or contribution), for a total period not to exceed eighteen (18) months following the Termination Date, whether Executive is participating in such plans as a Director or pursuant to an election under COBRA. The Company may modify its obligation under this Section 6(b) to the extent reasonably necessary to avoid any penalty or excise taxes imposed on it in connection with the continued payment of premiums by the Company under the Patient Protection and Affordable Care Act of 2010, as amended or the Internal Revenue Code of 1986, as amended, provided that such modification preserves, to the greatest extent possible, the economic intent of this provision. The parties agree that all amounts paid or reimbursed by the Company for premiums with respect to Executive's participation in the Company's group health plans and ArmadaCare Plan from and after the Termination Date, whether as a direct participant or pursuant to an election under COBRA, shall be reported as taxable income to Executive.
