other applicable provisions of the Amended and Restated Loan Agreement, to be satisfied in respect of Morgan’s Welding within 5 Business Days after the date hereof (provided, that the time period for complying with any such requirements in respect of the owned real estate being acquired by Morgan’s Welding from Robert E. Morgan shall be 30 days). Borrowers hereby acknowledge that the failure of Borrowers to comply with the covenant in this Section 3 shall constitute an immediate Event of Default.

     7. Reaffirmation and Confirmation. Each Borrower hereby ratifies, affirms, acknowledges and agrees that the Amended and Restated Loan Agreement and the other Loan Documents represent the valid, enforceable and collectible obligations of such Borrower, and each Borrower further acknowledges that there are no existing claims,

defenses, personal or otherwise, or rights of setoff whatsoever with respect to the Amended and Restated Loan Agreement or any of the Loan Documents. Each Borrower hereby agrees that this Consent in no way acts as a release or relinquishment of the Liens and rights securing payments of the Obligations.
