Section 3.4          Severability. In case any provision in this Third Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby and such provision shall be ineffective only to the extent of such invalidity, illegality or unenforceability.

The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the UCC; notwithstanding anything herein to the contrary, neither the Trustee nor the Notes Collateral Agent is under any obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Trustee or the Notes Collateral Agent pursuant to reasonable procedures approved by the Trustee or the Notes Collateral Agent, as applicable.
