Form 503—General Information
(Assumed Name Certificate)
The attached form is drafted to meet minimal statutory filing requirements pursuant to the relevant code

the information on the certificate, a new certificate should be filed. The new certificate should be filed
within 60 days after the occurrence of the events which necessitate the f
