5. For Candidates who are presently in service, serving the last six months of training as on 1st November , 2013 and due to complete 3 years of training (including excess leave, if any) on or before 30th April , 2014.

I..................... Hereby certify that Mr./Ms .......................... presently serving under me as an articled assistant / audit assistant, will be in service as on 1st November, 2013 serving the last six month of training and his / her due date of completion (including excess leave , if any) will be .................. i.e on or before 30th April, 2014 as per deed of articles.
