2. Lease.

A. Borrowed Employee Services. Upon the terms and subject to the conditions contained herein, Lessor shall loan to Lessee Borrowed Employee to act as Interim Chief Executive Officer of Lessee on a temporary basis while a search is conducted for a permanent Chief Executive Officer.

 

B. Borrowed Employee’s Employment Status. During the period of the loan of Borrowed Employee to Lessee, Borrowed Employee shall be the “borrowed servant” of Lessee as that term is defined by all applicable workers’ compensation statutes, decisions, regulations, and programs. Lessee has selected Borrowed Employee for the position of Interim Chief Executive Officer of Lessee, and Lessee has the right to discharge Borrowed Employee from that position. Lessee shall have direct and sole control of Borrowed Employee during the period of his loan to Lessee, and shall assign Borrowed Employee work duties and provide day-to-day supervision of Borrowed Employee. Borrowed Employee shall be instructed that he shall represent Lessee when dealing with third parties and should not take actions that could be construed as actions or representations on behalf of Lessor, nor shall he execute documents which purport to bind Lessor. Lessee shall provide Borrowed Employee with Lessee business cards for this purpose.

 

C. Compensation of Borrowed Employee. Lessor shall continue to (i) process and pay wages and other compensation for Borrowed Employee; (ii) withhold, collect, report and/or remit applicable federal, state and local taxes; (iii) make other deductions; and, (iv) to the extent permitted by the Plans and by applicable law, provide the benefits to which Borrowed Employee is entitled pursuant to the Plans, in each case, in a timely manner. However, Lessee shall be responsible for the direct payment of, or reimbursement to Borrowed Employee of, all travel and incidental

expenses of Borrowed Employee in traveling between his residence and Lessee’s place of business or otherwise traveling in connection with the business of Lessee.

D. Records. Lessor shall maintain books and records relating to Borrowed Employee in a manner consistent with normal practice of Lessor.

E. Limitation on Lessor’s Obligations. Notwithstanding anything herein to the contrary, no provision of this Agreement shall obligate Lessor to loan Borrowed Employee to Lessee pursuant to Section 2.A. above or provide any of its own services hereunder if Lessor reasonably determines, in its discretion, that to do so would: (i) interfere with the conduct of its business in the ordinary course, (ii) violate any applicable law, rule, regulation, judgment, injunction order or decree, (iii) constitute a default or give rise to any right of termination, cancellation or acceleration of any right or to a loss of any benefit to which Lessor is entitled under any provisions of any agreement or other instrument binding on Lessor; or (iv) violate any obligation or duty owed by Borrowed Employee to Lessor. If Lessor reasonably determines, in its discretion, that it cannot loan Borrowed Employee for any of the foregoing reasons, any term or provision of this Agreement requiring such loan shall be modified by the parties so as to make the loan possible hereunder or this Agreement shall be immediately terminable by written notice by Lessor, without liability to Lessee, at the sole option of Lessor.

3. Fees And Expenses.

A. Payment Of Services Fee. The fee for Borrowed Employee’s services hereunder shall be thirty thousand dollars ($30,000) per month (the “Fee”). Notwithstanding the foregoing, the parties acknowledge and agree that Lessee shall pay directly or reimburse Borrowed Employee directly for his payment of all travel, accommodation, meal and other similar expenses incurred by Borrowed Employee in the performance of his duties for Lessee (including traveling between Borrowed Employee’s residence and Lessee’s place of business or otherwise traveling in connection with the business of Lessee). However, in the event that Lessor pays or reimburses Borrowed Employee for any actual out-of-pocket expenses incurred in the course of Borrowed Employee’s performance of his duties for Lessee hereunder, Lessor shall submit an invoice to Lessee for, and Lessee shall pay Lessor, such expenses.

B. Method of Reimbursement. Lessor will invoice Lessee not more frequently than monthly for the Fee for the preceding month(s), from the effective date of this Agreement through its termination. Within thirty (30) days after receiving each such invoice Lessee shall wire transfer to a Lessor bank account designated by Lessor immediately available funds equal to the amount set forth in such invoice.

C. Interest. Interest will accrue on all moneys payable under this Agreement that are not paid on or before ninety (90) days from Lessee’s receipt of the applicable invoice. The interest rate will equal the “Applicable Federal Rate” (short term) as defined by Internal Revenue Code Section 1274(d), adjusted and compounded on a monthly basis. Upon the request of Lessee, Lessor shall provide Lessee with the Applicable Federal Rate in effect for any overdue payments. Payments will be applied against the oldest balances first.

4. Term; Termination of Borrowed Employee Services.

A. Term. This Agreement shall become effective as of the date first stated above and shall remain in force until terminated by either party in accordance with the provisions of this Section 4. Upon termination of this Agreement, all obligations of the parties with respect to such Borrowed Employee under this Agreement shall cease, except as otherwise provided herein.

B. Termination by Lessee. Lessee may, in its sole discretion, terminate this Agreement at any time by providing fifteen (15) days’ advance written notice to Lessor.
