that have not been disclosed to the Bank in writing.

compliance with all of the covenants in the Loan Documents, that no Default exists under any of the Loan Documents and that none of them is aware of any event that would, with or without notice, the passage of time, or both, be reasonably likely to
result in a Default under the Loan Agreement. 

  

	 	11.4	Affiliate Transactions. Without the prior written consent of Bank which shall not be unreasonably withheld, conditioned or delayed, neither the Borrowers nor any
Borrower Subsidiaries will enter into any transaction, other than the Acquisition or as otherwise permitted in the Loan Agreement, as amended from time to time, with Foundation on terms less favorable to the Borrower or Borrower Subsidiary than such

	 	-4-	  	
	 AND RESTATED LOAN AGREEMENT
	 	  	

 12. Release. On execution of this Amendment, each of the Borrowers and the Guarantors hereby
unconditionally and irrevocably release, acquit, waive and forever discharge the Bank and its participants, subsidiaries, affiliates, directors, officers, shareholders, employees, agents, attorneys, representatives and each of their respective
heirs, legal representatives, executors, administrators, successors and assigns (the “Released Parties”) from any and all duties, obligations, representations, claims, actions, suits, causes of action, demands, liabilities, losses,
damages, contracts, agreements, obligations, accounts, defenses and offsets of any kind or character whatsoever, known or unknown, suspected or unsuspected, in contract or in tort, at law or in equity, asserted or assertable, now existing or
hereafter to accrue which the Borrowers or Guarantors ever had, now have or may hereafter have against the Released Parties, jointly or severally, for or by any reason or matter, cause or thing whatsoever occurring prior to the date of this
Agreement, including without limitation such claims and defenses as fraud, mistake, duress and usury which relate, in whole or in part, directly or indirectly, to (a) the Loan Documents, the loan transactions evidenced thereby or any agreements
or commitments in connection therewith; and (b) any past or present account relationship of the Borrowers, the Guarantors or any of their affiliates with the Bank. In addition, the Borrowers and Guarantors each agree not to sue any of the
Released Parties regarding any of the foregoing matters. 
 13. Oliver Guaranty. Contemporaneously with the execution and delivery of
this Amendment, Oliver, OCH and the Trust (together, the “Oliver Guarantors”) will execute and deliver the First Amendment to Application Agreement in the form of Exhibit “A” and the failure to do so will constitute a Default. If
the Acquisition has not been consummated on or before December 31, 2012, all prior consents of the Bank to the Acquisition or related to any aspect of the Acquisition will be deemed withdrawn effective on January 1, 2013, whether contained
in the Loan Agreement or herein; provided, however, to the extent not specifically related thereto, all terms and conditions of the Loan Agreement, as amended, shall remain in full force and effect. 

14. Effectiveness. This Amendment may be executed in counterparts, each of which will be deemed an original document, but all of which will
constitute a single document. This Amendment will not be binding on or constitute evidence of a contract between the parties until such time as a counterpart of this document has been executed by each party and the Bank has received original
signatures from each of the parties. 
 15. Supersession. Except as specifically amended by this Amendment, the Loan Agreement and the
other Loan Documents remain in full force and effect.
