Independent Accountants' Report


The Board of Directors and Stockholder
Option One Mortgage Corporation:


We have examined management's assertion that Option One Mortgage Corporation
complied with the minimum servicing standards set forth in the Mortgage Bankers
Association of America's Uniform Single Attestation Program for Mortgage Bankers
as of and for the year ended December 31, 2003. Management is responsible for
Option One Mortgage Corporation's compliance with those minimum servicing
standards. Our responsibility is to express an opinion on management's assertion
about the Company's compliance based on our examination.


Our examination was conducted in accordance with attestation standards
established by the American Institute of Certified Public Accountants and,
accordingly, included examining, on a test basis, evidence about Option One
Mortgage Corporation's compliance with the minimum servicing standards specified
above and performing such other procedures as we considered necessary in the
circumstances. We believe that our examination provides a reasonable basis for
our opinion. Our examination does not provide a legal determination on Option
One Mortgage Corporation's compliance with the minimum servicing standards.


In our opinion, management's assertion that Option One Mortgage Corporation
complied with the aforementioned minimum servicing standards during the year
ended December 31, 2003 is fairly stated, in all material respects.
