Re:      CorTS Trust for The Boeing Company Notes (the "Trust")

Ladies and Gentlemen:

We have examined management's assertions that the Depositor and the Trustee have
complied,  in all  material  respects,  with the  provisions  of the Base  Trust
Agreement  dated as of December 15, 2000, as supplemented by the CorTS Trust for
The  Boeing  Company  Notes  Series  Supplement,  dated  as of  April  23,  2004
(together,  the "Trust  Agreement"),  during  the  period  covered by the annual
report on Form 10-K filed by the  Depositor  on behalf of the Trust for the year
ended December 31, 2006 (the "Annual  Report").  Management is  responsible  for
compliance with the Trust Agreement. Our responsibility is to express an opinion
on management's assertions based on our examination.

Our  examination  was  made in  accordance  with  standards  established  by the
American  Institute of Certified Public Accountants and,  accordingly,  included
examining,  on a test basis,  evidence about the  Depositor's  and the Trustee's
compliance  with the Trust  Agreement and  performing  such other  procedures as
considered  necessary  in the  circumstances.  We believe  that our  examination
provides a reasonable basis for our opinion.

In our opinion,  the  Depositor and the Trustee have  complied,  in all material
respects,  with the Trust  Agreement  during  the  period  covered by the Annual
Report and  management's  assertions  with respect to such compliance are fairly
stated, in all material respects, for the year ended December 31, 2006.
