Ladies and Gentlemen:

We have acted as counsel to DAOU Systems, Inc., a Delaware corporation (the
"Company"), in connection with its filing with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Securities Act"),
of a Registration Statement on Form S-3, including exhibits thereto (the
"Registration Statement"), covering up to 270,843 shares of the Company's Common
Stock, par value $0.001 per share (the "Shares").

We have examined the originals, or photostatic or certified copies, of such
records of the Company, certificates of officers of the Company and of public
officials, and such other documents as we have deemed relevant and necessary as
the basis of the opinion set forth below.  In such examination, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as photostatic or certified copies and the authenticity of the originals
of such copies.

Based upon our examination, we are of the opinion that the Shares have been
validly authorized and are legally issued, fully paid and non-assessable.

We express no opinion as to the applicability of, compliance with, or effect of
federal law or the law of any jurisdiction other than the General Corporation
Law of the State of Delaware.

We hereby consent to the use of our opinion as herein set forth as an exhibit to
the Registration Statement and to the use of our name under the caption "Legal
Matters" in the prospectus forming a part of the Registration Statement.  This
consent is not to be construed as an admission that we are a person whose
consent is required to be filed with the Registration Statement under the
provisions of the Securities Act.

Very truly yours,

/s/ BAKER & MCKENZIE
