Any party delivering an executed counterpart of this Amendment by facsimile or other electronic method of transmission also shall deliver an original executed counterpart of

this Amendment but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Amendment.

14.    THE BORROWERS, FOR THEMSELVES, THEIR SUBSIDIARIES (IF ANY) AND THE GUARANTOR AND LENDER HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY IN ANY LITIGATION RELATING TO THIS AMENDMENT OR THE DEBT AS AN INDUCEMENT TO THE EXECUTION OF THIS AMENDMENT.
