Re: Proxy Statement of CliniCom Incorporated
and Prospectus of HBO & Company
---------------------------------------------------
Dear Sirs:
We have acted as counsel to CliniCom Incorporated in connection with the
Registration Statement on Form S-4, to which this opinion appears as Exhibit 8
(the "Registration Statement"), which includes the Proxy Statement of CliniCom
Incorporated and the Prospectus of HBO & Company. Unless otherwise indicated,
any capitalized terms used herein shall have the same meanings that such terms
have in the Proxy Statement/Prospectus. Based upon certain representations as to
factual matters that we have received from CliniCom, certain shareholders of
CliniCom and HBO & Company, we confirm that in our opinion the statements
attributed to us in the Proxy Statement/ Prospectus under the heading "Certain
Federal Income Tax Consequences" are accurate in all material respects.
We hereby consent to the filing with the Securities and Exchange Commission
of this opinion as an exhibit to the Registration Statement and to the
references to this firm in the Proxy Statement/ Prospectus constituting part of
the Registration Statement.
Very truly yours,
/s/
DAVIS, GRAHAM & STUBBS, L.L.C.
