                             SECURED PROMISSORY NOTE
                                  (this "Note")


     1. FOR VALUE RECEIVED, C5 Health, Inc., a Delaware corporation  (Borrower),
unconditionally  promises  to  pay  to  MillenniumHealth  Communications,   Inc.
(Noteholder), by or before July 31, 2002, (the Principal Maturity Date), the sum
of $460,000 (the Principal Amount),  without interest on the Principal Amount if
this Note is paid without  occurrence of an Event of Default,  but if such Event
of Default  occurs,  then interest shall accrue at the rate of 8 1/2% per annum.
Interest, if any shall accrue hereunder, shall be computed for the actual number
of days elapsed on the basis of a year  consisting of 360 days, and all payments
made under this Note shall be applied first, to any amounts of interest due, and
then to principal.

     2. Borrower shall have the right to prepay the Principal Amount in whole or
part at any time or times without penalty.

     3. The happening of any of the following  events shall  constitute an event
of default (an Event of Default) under this Note: (a) the failure to pay amounts
payable hereunder by not later than the Principal Maturity Date; (b) the failure
by Borrower  to observe or perform and  covenant  contained  herein;  or (c) the
validity or  enforceability  of this Note shall be  contested  by  Borrower,  or
Borrower shall deny that it has any liability  hereunder.  Upon occurrence of an
Event of  Default,  Noteholder  at its  option  may  declare  all of  Borrower's
obligations hereunder (the Obligations) immediately due and payable and exercise
all of its rights  and  remedies  against  Borrower.  The  rights,  options  and
remedies of Noteholder shall be cumulative and no failure or delay by Noteholder
in exercising any right, option or remedy shall be deemed a waiver thereof or of
any  other  right,  option  or  remedy,  or a waiver  of any  Event  of  Default
hereunder.

     4. The payment this Note and the  performance of Borrower's  Obligations to
Noteholder  hereunder are secured by a security  interest in the form of lien on
certain and all of the assets sold and  conveyed to the Borrower by the terms of
an Asset  Purchase  Agreement of even date herewith (the Acquired  Assets),  and
evidenced by a Financing Statement (UCC-1) duly filed of record with the Florida
Department of State, the state wherein the Borrower's  principal office, and the
Acquired Assets are located.

     5. If the Principal Amount plus all accrued interest,  if any, are not paid
when due,  whether at the Principal  Maturity Date or upon  acceleration,  of if
this Note is collected  through a bankruptcy or other court,  whether  before or
after  the  Principal  Maturity  Date,  Borrower  agrees  to pay  all  costs  of
collection  incurred by  Noteholder,  including  but not  limited to  reasonable
attorneys' fees.

     6. Borrower hereby (a) waives  presentment,  demand and notice of dishonor,
protest,  extension,  and all other documents and notices in connection with the
delivery,  acceptance,  performance and enforcement of this Note, as well as the
benefit of any exemption provided debtors under law.

waives and renounces all of his equities or rights in this Note in favor of each
such  bona fide  purchase,  and each such  bona  fide  purchaser  shall  acquire
