To: Hara Yoshinorkhara@jstmail.co.jp＞ From: Bob Collins Date: June 30 Subject: July Meeting As discussed over the phone, we are planning to attend the workshop in Osaka. Our president and management continue to be impressed with your aggressive marketing and rising sales figures in Japan. After the workshop, I want to visit the manufacturing plant to see how they are making our mobile phones. Jim Hamilton, my assistant and I are still planning to arrive in Japan on July 3rd, and we expect to depart on July 8th. I am hoping that we can move our previously scheduled meeting to one day earlier. On July 5th I will need to meet instead with Jessica Park, who will be in Osaka for just one day before returning to Seoul. I apologize for this abrupt change of schedule. I am looking forward to seeing you soon. Thanks. Bob Collins Marketing Manager
