Compensation:  Your starting salary will be $720,000 annually, less applicable withholding, and paid bi-weekly in accordance with MTS' payroll procedures. You have voluntarily agreed to reduce your base pay by 20% beginning on your start date through the end of the fiscal year or if extended as previously agreed to by the Board of Directors. This reflects a temporary salary of $576,000 annually.

Equity Compensation:  You will receive an equity grant equal in value of $450,000. The date of grant will be the 15^th of the month after your month of hire. It will be provided in the form of 100% Restricted Stock Units. You will also receive monthly grants of Restricted Stock Units in the amount of $150,000 per month commencing on September 15, 2020, and continuing until the appointment of a full-time, permanent President and CEO. All Restricted Stock Units will vest at the earlier of the first anniversary of your appointment as Interim President and CEO or upon the appointment of a full-time, permanent President and Chief Executive Officer.

Health & Welfare Benefits:  On your first day of employment, you will be eligible to enroll in many insurance programs including Medical, Preventive Vision, Dental, Life Insurance, and Short and Long-Term Disability as well as tax-advantaged savings plans to include (FSA) Flexible Spending and (HSA) Health Savings Accounts.
