 5.12 Legend on Share Certificates. 

Each certificate representing any Shares issued after the date hereof shall be endorsed by the Company with a legend reading
substantially as follows: 
 “THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A VOTING AGREEMENT, AS MAY BE AMENDED FROM TIME TO

 The Company, by its execution of this Agreement,

of a certificate evidencing Shares upon written request from such holder to the Company at its principal office. The Parties to this Agreement do hereby agree that the failure to cause the certificates evidencing the Shares to bear the legend
required by this Section 5.12 herein and/or the failure of the Company to supply, free of charge, a copy of this Agreement as provided hereunder shall not affect the validity or enforcement of this Agreement. 

5.13 Stock Splits, Stock Dividends, etc. 
 In the event of any issuance of Shares of the Company’s voting securities hereafter to any of the Stockholders (including, without limitation, in connection with any stock split, stock dividend,

at the request of any other Party, to execute and deliver any further instruments or documents and to take all such further action as the other Party may reasonably request in order to evidence or effectuate the consummation of the transactions
contemplated hereby and to otherwise carry out the intent of the Parties hereunder. 
 5.16 Delays or Omissions.

 No delay or omission to exercise any right, power or remedy accruing to any Party under this Agreement, upon any breach or
default of any other Party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting Party nor shall 

  
 11 









 
it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach
or default be deemed a waiver of any other breach or default previously or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any Party of any breach or default under this Agreement, or any waiver
on the part of any Party of any provisions or conditions of this Agreement, must be in a writing executed by such Party and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by
law or otherwise afforded to any party, shall be cumulative and not alternative.
