From: Linda Rogers To: Nicholas Taylor Subject: Workshop date Date: July 15 Dear Mr. Taylor, Please disregard the e-mail I sent you on July 13. I mistyped the date of the team building workshop. I am sorry for making you confused. It will be held on July 20, not July 29. Joan in Marketing and Edward in Sales will be going as well.

We will need to submit the registration forms before July 17. Thank you. Linda Human Resources
