Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not
affect the interpretation thereof.

 

Section 3.6
Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision
hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu
of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement
a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.
