(b) Lender hereby waives the violation of Section 12(o) of the Loan Agreement (which would occur unless Lender executed and delivered this Amendment) arising solely as a result of Metretek Technologies amending their organizational documents in connection with the Transaction as described in the Memo. (c) Lender hereby waives any Event of Default that may occur under Section 14(j) of the Loan Agreement arising solely as a result of any change of control that may be caused by the issuance of shares and warrants contemplated by the Transaction as described in the Memo. Nothing herein is intended to or shall waive any other Event of Default under the Loan Agreement arising out of the Transaction or otherwise or any event that with notice, the passage of time or both may become an Event of Default under the Loan Agreement arising out of the Transaction or otherwise. 2.
