(a) Even against a purchaser for value and without notice, the terms of a certificated security include terms stated on the certificate and terms made part of the security by reference on the certificate to another instrument, indenture, or document or to a Constitution, statute, ordinance, rule, regulation, order or the like, to the extent the terms referred to do not conflict with terms stated on the certificate. A reference under this subsection does not of itself charge a purchaser for value with notice of a defect going to the validity of the security, even if the certificate expressly states that a person accepting it admits notice. The terms of an uncertificated security include those stated in any instrument, indenture, or document or in a Constitution, statute, ordinance, rule, regulation, order or the like, pursuant to which the security is issued.
(b) The following rules apply if an issuer asserts that a security is not valid:
(1) A security other than one issued by a government or governmental subdivision, agency or instrumentality, even though issued with a defect going to its validity, is valid in the hands of a purchaser for value and without notice of the particular defect unless the defect involves a violation of a Constitutional provision. In that case, the security is valid in the hands of a purchaser for value and without notice of the defect, other than one who takes by original issue.
