Accrued Obligations – The Parties agree that Executive is entitled to receive, in accordance with the Company’s regular payroll practices, all unpaid base salary earned through the Separation Date, including any amounts for accrued unused vacation time to which Executive is entitled through such date in accordance with Company policy, and reimbursement of any properly incurred unreimbursed business expenses incurred through the Separation Date (together, the “Accrued Obligations”). As of the Separation Date, all salary payments from the Company ceased and any benefits Executive had as of the Separation Date under Company-provided benefit plans, programs, or practices terminated, except as required by federal or state law or as otherwise specifically set forth in this Agreement.  

2.

Separation Benefits – Provided that Executive: (i) has, effective as of the Separation Date, resigned from employment with the Company, and from his positions as President and Chief Executive Officer of the Company, and from any and all other positions he held as an officer of the Company and/or as a member of the Board, (ii) signs and returns this Agreement no earlier than the Separation Date but no later than June 1, 2018, and (iii) does not revoke his agreement as set forth in Section 14 below, the Company will provide Executive with the following separation benefits (the “Separation Benefits”):

a.

Severance Pay – Commencing on the Company’s first regularly scheduled payroll date that follows the Agreement Effective Date (as defined below) (the “Payment Commencement Date”) and continuing for a twelve (12) month period thereafter (the “Severance Period”), Executive will receive salary continuation payments, in equal installments in accordance with the Company’s regular payroll practices, in an aggregate amount equal to one (1) year of Executive’s base salary as of the Separation Date (“Salary Continuation”).  The Salary Continuation payments will be subject to all applicable taxes and withholdings.  

b.

Group Health Insurance – Should Executive be eligible for and timely elect to continue receiving group health and/or dental insurance coverage under the law known as COBRA, the Company shall, continuing until the earlier of (x) the expiration of the Severance Period, and (y) the date on which Executive becomes eligible to receive group health insurance coverage through another employer (as applicable, the “COBRA Contribution Period”), pay on Executive’s behalf the portion of the monthly premiums for such coverage that it pays for active and similarly situated employees receiving the same type of coverage.  The balance of such premiums during the COBRA Contribution Period, and all premium costs thereafter, shall be paid by Executive on a monthly basis during the elected period of health insurance coverage under COBRA for as long as, and to the extent that, he remains eligible for and elects to remain enrolled in COBRA continuation coverage. Executive agrees that, should he become eligible during the Severance Period to receive group health insurance coverage through another employer, he immediately shall notify the Company in writing of the date of eligibility for such coverage.

Accelerated Vesting of Stock Options – Effective as of the Agreement Effective Date, and notwithstanding the terms of the Company’s 2006 Stock Incentive Plan, 2016 Stock Incentive Plan or 2017 Stock Incentive Plan, or the stock option agreements between Executive and the Company in connection therewith dated June 18, 2015 for 329,334 shares of common stock (the “2015 Option”), March 2, 2017 for 159,001  shares  of common stock (the “March 2017 Option”) and July 25, 2017 for 157,449 shares of common stock (the “July 2017 Option”), the Company will accelerate the vesting of: (i) the 2015 Option, such that the number of shares vested as of the Agreement Effective Date will be 274,445, (ii) the March 2017 Option, such that the number of shares vested as of the Agreement Effective Date will be 66,250 and (iii) the July 2017 Option, such that the number of shares vested as of the Agreement Effective Date will be 49,202 (all such accelerated options, collectively, the “ Accelerated Options”). The Accelerated Options will remain exercisable with respect to shares that would have vested as of the Separation Date in the absence of this Section 2(c), and will also be deemed exercisable with respect to any additional shares vested pursuant to this Section 2(c), for the period set forth in Section 2(d) below.

d.

Extended Option Exercise Period – Effective as of the Agreement Effective Date, the Company will extend, until such date that is twenty-four (24) months following the Separation Date, the exercise period for all outstanding options to purchase shares of the Company's common stock in which Executive has vested, including pursuant to Section 2(c) above. Executive understands that options subject to this extended exercise period shall cease to be treated for tax purposes as an incentive stock option.

e.

Bonus Eligibility – The Company agrees that Executive will be eligible for a performance-based bonus of up to $87,166 based on the Company’s achievement of performance milestones agreed to by the Company and Executive for 2018 at the March 2018 Board of Directors meeting, as determined by the Board in its sole discretion.
