9. Miscellaneous.

9.1 The Company, regardless of the time, order or place of signing, waives presentment, demand, protest and notices of any kind in connection with the enforcement of this Note. If the Company fails to comply with any of the provisions of this Note, the Company will pay to the Holder of this Note, on demand, such further amounts as shall be sufficient to cover the costs and expenses, including but not limited to reasonable attorneys’ fees and disbursements, incurred by the Holder of this Note in collecting upon this Note or otherwise enforcing any of the Holder’s rights hereunder.

9.2 The rights and remedies herein reserved to any party shall be cumulative and in addition to any other or further rights and remedies available at law or in equity. No delay or omission on the part of the Holder in exercising any right hereunder shall operate as a waiver of such right or of any other right of such Holder. The waiver by any party hereto of any breach of any provision of this Note shall not be deemed to be a waiver of the breach of any other provision or any subsequent breach of the same provision.

9.4 The Company and the Holder irrevocably agree that all legal proceedings arising out of or in connection with this Note, including its enforcement, will be tried in a court of competent jurisdiction by a judge without a jury.
