1.       Certain Defined Terms. Capitalized terms used herein not otherwise
defined shall have the meanings ascribed thereto in the Purchase Agreement. As
used herein the following terms, unless the context otherwise requires, have the
following respective meanings:

         (a)      The term "Company" shall include Metropolitan Health Networks,
         Inc. and any corporation that shall succeed or assume the obligations
         of such corporation hereunder.

         (b)      The term "Common Stock" includes (a) the Company's common
         stock, $.001 par value per share, (b) any other capital stock of any
         class or classes (however designated) of the Company, authorized on or
         after such date, the holders of which shall have the right, without
         limitation as to amount, either to all or to a share of the balance of
         current dividends and liquidating dividends after the payment of
         dividends and distributions on any shares entitled to preference, and
         the holders of which shall ordinarily, in the absence of contingencies,
         be entitled to vote for the election of a majority of directors of the
         Company (even though the right so to vote has been suspended by the
         happening of such a contingency) and (c) any other securities into
         which or for which any of the securities described in (a) or (b) may be
         converted or exchanged pursuant to a plan of recapitalization,
         reorganization, merger, sale of assets or otherwise.

         (c)      The term "Other Securities" refers to any stock (other than
         Common Stock) and other securities of the Company or any other person
         (corporate or otherwise) that the Holder of this Warrant at any time
         shall be entitled to receive, or shall have received, on the exercise
         of this Warrant, in lieu of or in addition to Common Stock, or that at
         any time shall be issuable or shall have been issued in exchange for or
         in replacement of Common Stock or Other Securities pursuant to Section
         4 or otherwise.

2.       Exercise of Warrant.

         2.1      Method of Exercise.

         (a)      This warrant may be exercised in whole or in part (but not as
         to a fractional share of Common Stock), at any time and from time to
         time during the Exercise Period by the Holder hereof by delivery of a
         notice of exercise (a "Notice of Exercise") substantially in the form
         attached hereto as Exhibit A via facsimile to the Company. Promptly
         thereafter the Holder shall surrender this Warrant to the Company at
         its principal office, accompanied by payment of the Purchase Price
         multiplied by the number of shares of Common Stock for which this
         Warrant is being exercised (the "Exercise Price"). Payment of the
         Exercise Price shall be made, at the option of the Holder, (i) by check
         or bank draft payable to the order of the Company, or (ii) by wire
         transfer to the account of the Company. Upon exercise, the Holder shall
         be entitled to receive, promptly refund the excess to the Holder. Upon
         exercise, the Holder shall be entitled to receive, promptly after
         payment in full, one or more certificates, issued in the Holder's name
         or in such name or names as the Holder may direct, subject to the


<PAGE>


         limitations on transfer contained herein, for the number of shares of
         Common Stock so purchased. The shares of Common Stock so purchased
         shall be deemed to be issued as of the close of business on the date on
         which the Company shall have received from the Holder payment in full
         of the Exercise Price (the "Exercise Date").

         (b)      Notwithstanding anything to the contrary set forth herein,
         upon exercise of all or a portion of this Warrant in accordance
         with the terms hereof, the Holder shall not be required to physically
         surrender this Warrant to the Company. Rather, records showing the
         amount so exercised and the date of exercise shall be maintained on a
         ledger substantially in the form of Annex B attached hereto (a copy of
         which shall be delivered to the Company or transfer agent with each
         Notice of Exercise). It is specifically contemplated that the Holder
         hereof shall act as the calculation agent for all exercises of this
         Warrant. In the event of any dispute or discrepancies, such records
         maintained by the Holders shall be controlling and determinative in the
         absence of manifest error. The Holder and any assignee, by acceptance
         of this Warrant, acknowledge and agree that, by reason of the
         provisions of this paragraph, following an exercise of a portion of
         this Warrant, the number of shares of Common Stock represented by this
         Warrant will be the amount indicated on Annex B attached hereto (which
         may be less than the amount stated on the face hereof).

         2.2      Representations of Holder. The Holder hereof represents and
warrants to the Company that it has acquired this Warrant and anticipates
acquiring the shares of Common Stock issuable upon exercise of the Warrant
solely for its own account for investment purposes and not with a view to or for
resale of such securities unless such resale has been registered with the
Commission or an applicable exemption is available therefore. At the time this
Warrant is exercised, the Company may require the Holder to state in the Notice
of Exercise such representations concerning the Holder as are necessary or
appropriate to assure compliance by the Holder with the Securities Act.

         2.3      Company Acknowledgment. The Company will, at the time of the
exercise of this Warrant, upon request of the Holder hereof, acknowledge in
writing its continuing obligation to afford to such Holder the registration
rights to which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of a Registration Rights Agreement dated the date
hereof (the "Registration Rights Agreement"). If the Holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford such Holder any such rights.

         2.4      Limitation on Exercise. Notwithstanding the rights of the
Holder to exercise all or a portion of this Warrant as described herein, such
exercise rights shall be limited, solely to the extent set forth in the Purchase
Agreement as if such provisions were specifically set forth herein. In addition,
the number of shares of Common Stock issuable upon exercise of this Warrant is
subject to reduction as specified in Section 10.3 of the Purchase Agreement.

         2.5      Mandatory Exercise. In the event the volume weighted average
sales price for the Common Stock, as reported on Bloomberg, L.P., is greater
than or equal to $1.50


<PAGE>


for 60 consecutive Trading Days at any time after the Closing Date, the Holder
shall be required to exercise the Warrant in full and in accordance with the
terms provided herein; provided, however, this Section 2.5 shall be void if the
Registration Statement is not effective with the Commission on the date such
mandatory exercise is triggered.

3.       Delivery of Stock Certificates, etc., on Exercise. As soon as
practicable after the exercise of this Warrant, and in any event within three
(3) business days thereafter, the Company at its expense (including the payment
by it of any applicable issue, stamp or transfer taxes) will cause to be issued
in the name of and delivered to the Holder thereof, or, to the extent
permissible hereunder, to such other person as such Holder may direct, a
certificate or certificates for the number of fully paid and nonassessable
shares of Common Stock (or Other Securities) to which such Holder shall be
entitled on such exercise, plus, in lieu of any fractional share to which such
Holder would otherwise be entitled, cash equal to such fraction multiplied by
the then applicable Purchase Price, together with any other stock or other
securities and property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 2 or otherwise.

4.       Adjustment for Extraordinary Events. The Purchase Price to be paid by
the Holder upon exercise of this Warrant, and the consideration to be received
upon exercise of this Warrant, shall be adjusted in case at any time or from
time to time in the case of any stock split, dividends, mergers or
recapitalizations.

5.       No Impairment. The Company will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Holder of this Warrant against
impairment. Without limiting the generality of the foregoing, the Company (a)
will not increase the par value of any shares of stock receivable on the
exercise of this Warrant above the amount payable therefor on such exercise, (b)
will take all such action as may be reasonably necessary or appropriate in order
that the Company may validly and legally issue fully paid and unassessable
shares of stock on the exercise of this Warrant, and (c) will not transfer all
or substantially all of its properties and assets to any other person (corporate
or otherwise), or consolidate with or merge into any other person or permit any
such person to consolidate with or merge into the Company (if the Company is not
the surviving person), unless such other person shall expressly assume in
writing and will be bound by all the terms of this Warrant.

6.       Accountant's Certificate as to Adjustments. In each case of any
adjustment or readjustment in the shares of Common Stock (or Other Securities)
issuable on the exercise of this Warrant, the Company at its expense will
promptly cause independent certified public accountants in use at the time by
the Company to compute such adjustment or readjustment in accordance with the
terms of this Warrant and prepare a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based, including a statement of (a) the consideration received
or receivable by the Company for


<PAGE>


any additional shares of Common Stock (or Other Securities) issued or sold or
deemed to have been issued or sold, (b) the number of shares of Common Stock (or
Other Securities) outstanding or deemed to be outstanding, and (c) the Purchase
Price and the number of shares of Common Stock to be received upon exercise of
this Warrant, in effect immediately prior to such issue or sale and as adjusted
and readjusted as provided in this Warrant. The Company will forthwith mail a
copy of each such certificate to the Holder of this Warrant, and will, on the
written request at any time of the Holder of this Warrant, furnish to such
Holder a like certificate setting forth the Purchase Price at the time in effect
and showing how it was calculated. Such statement shall be binding absent
manifest error.

7.       Notices of Record Date, etc. In the event of

         (a)      any taking by the Company of a record of the holders of any
         class or securities for the purpose of determining the holders thereof
         who are entitled to receive any dividend or other distribution, or any
         right to subscribe for, purchase or otherwise acquire any shares of
         stock of any class or any other securities or property, or to receive
         any other right, or

         (b)      any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any transfer of all or substantially all the assets of the
         Company to or consolidation or merger of the Company with or into any
         other person, or

         (c)      any voluntary or involuntary dissolution, liquidation or
         winding-up of the Company,

then and in each such event the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, and
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any, as of which the holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares of Common Stock (or Other Securities) for then and in each such event the
Company will mail or cause to be mailed to the Holder of this Warrant a notice
specifying (i) the date on which any such record is to be taken for the purpose
of such dividend, distribution or right, and stating the amount of character of
such dividend, distribution or right, and (ii) the date on which any such
reorganization, reclassification, recapitalization, transfer, consolidation,
merger, dissolution, liquidation or winding-up is to take place, and the time,
if any, as of which the holders of record of Common Stock (or Other Securities)
shall be entitled to exchange their shares of Common Stock (or Other Securities)
for securities or other property deliverable on such reorganization,
reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up. Such notice shall be mailed at least 10
days prior to the date specified in such notice on which any action is to be
taken.

8.       Reservation of Stock, etc. Issuable on Exercise of Warrant. The Company
will at all times reserve and keep available, solely for issuance and delivery
on the exercise of this Warrant, all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of this Warrant.
