The Lender and the Loan Parties acknowledge and agree that the priority of Lender’s Liens, the exercise of certain of the Lender’s rights and remedies hereunder and under the other Loan Documents, the delivery or possession of certain possessory Collateral and other terms under the Loan Documents shall be subject to and restricted by the provisions of the Subordination Agreement.

(b)

Each of the Loan Parties and the Lender agree that in the event of any direct and irreconcilable conflict between the terms of any Loan Document and the Subordination Agreement, the terms of the Subordination Agreement shall govern and control.

(b)

Rights of the Lender.
