Company agrees to pay Tatum and to maintain a security deposit of $35,000 for the Company’s future payment obligations to both Tatum and the Tatum Partner under this Agreement (the “Deposit”).  If the Company breaches this Agreement and fails to cure such breach as provided in this Agreement, Tatum will be entitled to apply the Deposit to its damages resulting from such breach.  Upon termination or expiration of this Agreement, Tatum will return to the Company the balance of the Deposit remaining after application of any amounts to unfulfilled payment obligations of the Company to Tatum or the Tatum Partner as provided for in this Agreement.  Tatum shall return any unapplied portion of such Deposit no later than ten (10) business days following the termination or expiration of this Agreement, and to the extent that any amounts are not return to the Company, Tatum shall provide a detailed summary of the amount withheld, including a specific description of the amount owed, the basis for such amount withheld and documentation in support thereof.

Converting Interim to Regular Full-Time Employee

Term & Termination

This Agreement will terminate upon the effective date of termination or expiration of the Tatum Partner’s employment with the Company or upon the Tatum Partner ceasing to be a partner of Tatum.
