[单项选择]Dear Colleagues,
I regret to inform you that, from November 1st, Pedro Esposito will be leaving his current (38) as Area Marketing manager for Northern Europe.
I know that this has not been an easy decision for him but he (39) that this is the right moment for him to accept a new challenge in another field of activity. The two years that he has spent working with us have been extremely rewarding ones and we can all be very proud of the way our company has (40) in an increasingly competitive marketplace.
Winning the health industry marketing award for the second time is a fitting tribute to both his leadership (41) and to the quality of the team that worked with him. David Haskoff will be taking over from Pedro at the end of this month and I would be very grateful if you could attend the informal meeting that I have organized on Wednesday October 20th which will give me the opportunity to introduce him to you all.
Yours sincerely,<
