RE:  AUL American  Individual  Variable Life Unit Trust Modified  Single Premium
     Policy (File No. 333-32553)

Dear Sir or Madam:

This is to certify that the most recent amendment to the Registration  Statement
of the AUL  American  Individual  Variable  Life Unit Trust's  Flexible  Premium
Adjustable Variable Life Insurance Policy,  File No. 333-32531,  (the Registrant
also  has a  Registration  Statement,  filed  under  separate  cover,  File  No.
333-32553),  was filed electronically and that the form of prospectus that would
have been filed under  paragraph (b) or (c) of Rule 497 under the Securities Act
of 1933 does differ slightly from those  contained in the most recent  amendment
to the  Registration  Statement in that the form of  prospectus  that that would
have been filed under  paragraph (b) or (c) of Rule 497 under the Securities Act
of 1933, is dated May 2, 2008.

No fees are required in  connection  with this  filing.  Please call me at (317)
285-1588 with any questions or comments regarding the attached.

Cordially,

/s/ Richard M. Ellery
