You are referred to herein individually as a “Holder” and collectively as the “Holders.” Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them in the Note Agreement.

In connection with this transaction EWC LP Corp., a Delaware corporation and a Restricted Subsidiary, is also merging into GP Corp. prior to the merger of GP Corp. into the Parent.

This waiver is limited to its terms, is conditioned upon an identical waiver by the banks under the Credit Agreement, and shall not constitute a waiver of any other term, condition, representation or covenant under the Note Agreement or any of the other agreements, documents or instruments executed and delivered in connection therewith.

2. ISSUANCE OF NEW NOTES
