COBRA Period. In satisfaction of Section 9.a(iv) of the Employment Agreement, provided that the Employee properly and timely completes and submits all of the necessary documentation relating to the receipt of COBRA coverage, the Company shall pay the premiums for medical, dental and vision COBRA continuation coverage for the Employee and the Employee’s spouse Cynthia L. White for a maximum of eighteen months after the Employment End Date, subject to shortening of this period if the Employee or the Employee’s COBRA qualified beneficiaries (i) become ineligible for COBRA continuation coverage, or (ii) voluntarily terminate their COBRA continuation coverage in favor of the “Subsequent Coverage” described in 3.b. below, before the end of that eighteen month period.

Subsequent Coverage. In satisfaction of Sections 7 and 8.c (as provided in Section 9a.(i)) of the Employment Agreement, after the expiration of COBRA coverage described above, the Company shall Provide (as defined below) the Employee’s spouse Cynthia L. White, at the Company expense, Health Care Insurance Benefits (as defined below) until October 31, 2019, and shall pay the Employee the additional severance amount set forth in Section 3.c. For purposes of this Section 3.b:

The term “Provide” (or “Provided” or “Provision”) means that the Company shall purchase and maintain, at the Company’s expense, an insurance policy providing Health Care Insurance Benefits for the Employee’s spouse, subject to the provisions of Section 3(b)(i)(A-C), below and subject to such insurance policy not constituting a discriminatory insured plan of the Company in violation of Sections 2716(a) and 2716(b)(1) of the Public Health Service Act (as added by Section 1001(5) of the Patient Protection and Affordable Care Act, as amended by Section 10101(d) thereof) (“Discriminatory Insured Plan”). However, if either the Company and the Employee’s spouse mutually agree in writing that, or if such insurance policy cannot be purchased or maintained by the Company without such insurance policy constituting a Discriminatory Insured Plan, the Employee’s spouse will purchase such an insurance policy, and “Provide” shall mean that the Company shall reimburse the Employee’s spouse for the cost of purchasing such coverage, subject to the provisions of Section 3.b.(i)(A)-(C), below. The Provision of Health Care Insurance Benefits for the Employee’s spouse shall be subject to the following:

The amount that the Company shall pay (or reimburse) for coverage Provided during any taxable year of the Employee’s spouse shall not affect the amount the Company shall pay (or reimburse) for coverage Provided during any subsequent taxable year of the Employee’s spouse;

Any reimbursement for coverage Provided during a taxable year of Employee’s spouse shall be made on or before the last day of the next taxable year of the Employee’s spouse; and

The Employees’ spouse’s right to coverage or reimbursement is not subject to liquidation or exchange for any other benefit.

The term “Health Care Insurance Benefits” shall mean individual insurance coverage that is comparable to the medical and dental benefits that are provided to the spouses of senior executives of the Company in September 2013, including but not limited to being comparable in terms of network (which network shall in all cases include the Mayo Clinic locations in Arizona, to the extent such a policy is available), prescription drug coverage, deductibles, copayments, coinsurance, reimbursement formula, and annual and lifetime out of pocket maximums.

Additional Severance. The Company shall pay the Employee an additional severance amount equal to $51,000, payable in equal bi-weekly installments during the Severance Period, as defined in the Employment Agreement, and in accordance with the same time and form of payment terms governing the time and form of payment of the amounts provided for under Section 9.a(ii) of the Employment Agreement.

Restricted Stock.

The Employee and the Company agree that, if at the date the Employee resigns from or otherwise ceases to a member of the Board (“Departure Date”), any shares of common stock of the Company that had been granted to the Employee prior to the Employment End Date remain subject to any restriction that has not lapsed in accordance with the terms applicable to the grant of such shares (“Restricted Shares”) then, the Company shall pay the Employee an amount in cash equal to the Fair Market Value (as defined below) of such Restricted Shares within thirty (30) days the Departure Date. For purposes of this Agreement, the Fair Market Value of the Restricted Shares shall be calculated as (x) the per-share closing price of the Company’s common stock as reported by the Wall Street Journal on the last trading day immediately prior to the Departure Date multiplied by (y) the number of Restricted Shares held by Employee on the Departure Date. The Employee and the Company agree that the Company’s payment to the Employee in accordance with this Section 4 shall completely satisfy the Company’s obligations to the Employee and the Employee’s rights with respect to any Restricted Shares held by the Employee on the Departure Date. Nothing in this Section 4 shall alter or amend the terms of any grant of common stock, restricted common stock or other compensation made to the Employee after the Employment End Date.

The Company and the Employee further agree that, while the Employee remains a member of the Board, he shall be deemed to remain in the service of the Company for purposes of any grant of Restricted Shares made prior to the Employment End Date and that any restrictions on such Restricted Shares shall continue to lapse in accordance with the terms of grant applicable to such shares.

Covenant Not To Compete & Confidentiality. The Employee acknowledges and agrees that the provisions of Sections 12 and 13 of the Employment Agreement shall continue in full force and effect and shall not be superseded by this Agreement.
