                    CERTIFICATE OF THE DESIGNATIONS, POWERS,

                             PREFERENCES AND RIGHTS
                                     OF THE
                            SERIES A PREFERRED STOCK
                                (PAR VALUE $.01)

                                       OF

                            MIRACOR DIAGNOSTICS, INC.

         The undersigned DOES HEREBY CERTIFY that the following Resolution was
duly adopted by the Board of Directors of MIRACOR DIAGNOSTICS, INC., a Utah
corporation (the "Corporation"), at a meeting held on March 3rd, 2004.

                  RESOLVED, that one series of a class of authorized Preferred
         Stock, $.01 Par Value, of the Corporation is hereby created and that
         the designations, powers, preferences and relative, participating,
         optional or other special rights of the shares of such series, and
         qualifications, limitations or restrictions thereof, are hereby fixed
         as follows (this instrument is hereinafter referred to as the
         "Designation"):

         1. NUMBER OF SHARES AND DESIGNATIONS. Two Million Seven Hundred Two
Thousand Seven Hundred Two (2,702,702) shares of the Preferred Stock, $.01 Par
Value, of the Corporation are hereby constituted as a series of Preferred Stock
of the Corporation designated as 3% Series A Preferred Stock (the "Series A
Stock").

         2. DIVIDEND PROVISIONS. The holders of shares of Series A Stock shall
be entitled to receive until conversion a dividend of $0.002775 cents per share
of Series A Stock per quarter. In addition each Series A Stock holder will be
entitled to receive dividends identical to any that may be paid to the holders
of Common Stock $0.15 Par Value per share (the "Common Stock") of the
Corporation or any other Capital Stock of the Corporation.

         3. RANK. The Series A Stock shall rank: (i) prior to all of the
Corporation's Common Stock; (ii) prior to any class or series of capital stock
of the Corporation hereafter created not specifically ranking by its terms
senior to or on parity with the Series A Stock (collectively, "Junior
Securities"); and (iii) on parity with any Series of Preferred Stock of the
Corporation and any class or series of capital stock of the Corporation
hereafter created specifically ranking by its terms on parity with the Series A
Stock (the "Parity Securities"), in each case as to the distribution of assets
upon liquidation, dissolution or winding up of the Corporation.

         4. LIQUIDATION PREFERENCE.

                  (a) Upon any liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary ("Liquidation"),
the holders of record of the shares of the Series A Stock shall be entitled to
receive, immediately after any distributions required by the Corporation's
Certificate of Incorporation and any Certificate(s) of Designation, powers,
preferences and rights, and before and in preference to any distribution or
payment of assets of the Corporation, an amount in cash equal to Thirty Seven
Cents ($0.37) per share (subject to adjustment in the event of stock splits,

<PAGE>

combinations or similar events), plus accrued and unpaid dividends through the
date of payment. If, upon such Liquidation, the assets of the Corporation
available for distribution to the holders of Series A Stock and/or any Parity
Securities (if any) shall be insufficient to permit payment in full to the
holders of the Series A Stock and/or the Parity Securities (if any), then the
entire assets and funds of the Corporation legally available shall be
distributed ratably among the holders of the Series A Stock and Parity
Securities (if any) based upon the proportion the total amount distributable on
each share upon liquidation bears to the aggregate amount available for
distribution on all shares of the Series A Stock and/or the Parity Securities
(if any).

                  (b) Upon the completion of the distributions required by
subparagraph (a) of this Paragraph 4, if assets remain in the Corporation, they
shall be distributed to holders of Junior Securities in accordance with the
Corporation's Certificate of Incorporation and any certificate(s) of
designation, powers, preferences and rights.

                  (c) For purposes of this Paragraph 4, a merger or
consolidation or a sale of all or substantially all of the assets of the
Corporation shall be considered a Liquidation except in the event that in such a
transaction, the holders of the Series A Stock receive securities of the
surviving corporation having substantially similar rights as the Series A Stock.

         5. CONVERSION. The holders of the Series A Stock shall have conversion
rights as follows (the "Conversion Rights"):

                  (a) VOLUNTARY CONVERSION. The holders of Series A Stock shall
have the right to convert their Series A Stock at any time into shares of Common
Stock of the Corporation; provided, however, that no holder may convert in any
ninety (90) day period (except for a period during which an automatic conversion
event shall have occurred) more than fifty percent (50%) of the number of shares
of Series A Stock initially acquired by the holder. The number of shares of
Common Stock into which each share of the Series A Stock shall be convertible is
collectively referred to as the "Conversion Rate." The initial Conversion Rate
shall be one-to-one subject to anti-dilution adjustments as provided herein.
Each share of Series A Stock shall be convertible after issuance of the
certificate at the office of the Corporation or any transfer agent for such
stock, or if there is none, then at the office of the transfer agent for the
Common Stock, or if there is no such transfer agent, at the principal executive
office of the Corporation, into that number of fully paid and non-assessable
shares of Common Stock of the Corporation equal to divided by the conversion
price in effect at the time of conversion (the "Conversion Price"), determined
as hereinafter provided. For purposes of this Paragraph 5(a), such conversion
shall be deemed to have been made immediately prior to the close of business on
the date of such surrender of the share(s) of Series A Stock to be converted,
and the person or persons entitled to receive the shares of Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Common Stock as of such date.

                  (b) AUTOMATIC CONVERSION. In the event the Corporation
consummates a "Liquidity Event" (which is defined as (i) any merger or
consolidation involving the Corporation, unless the Corporation is the surviving
entity in the merger or consolidation, (ii) any sale of all or substantially all
of the assets of the Corporation, or (iii) any tender of at least a majority of
the Company's outstanding shares of Common Stock), each share of Series A Stock
then outstanding shall, by virtue of such conditions and without any action on
the part of the holder thereof, be deemed automatically converted into that
number of shares of Common Stock into which the Series A Stock would then be
converted at the then effective Conversion Rate.

                  (c) MECHANICS OF CONVERSION. Before any holder of Series A
Stock shall be entitled to convert the Series A Stock into share(s) of Common
Stock, the holder shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or of any transfer agent for the
Series A Stock, and shall give written notice to the Corporation at its
principal corporate office, of the election to convert the same and shall state

                                       2

<PAGE>

therein the name or names in which the certificate or certificates for shares of
Common Stock are to be issued. The Corporation shall, as soon as practicable
thereafter, issue and deliver to such holder of Series A Stock, or to the
nominee or nominees of such holder, a certificate or certificates for the number
of shares of Common Stock to which such holder shall be entitled as aforesaid.
Such conversion shall be deemed to have been made immediately prior to the close
of business on the date of such surrender of the shares of Series A Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder of such shares of Common Stock as of such date.

                  (d) CONVERSION PRICE ADJUSTMENTS. The Conversion Price of the
Series A Stock shall be subject to adjustment from time to time as set forth
below:

                  (i) In the event of any new investments in the Corporation
         subsequent to the closing of the Series A Stock Round (each such
         investment, a "Next Round"), including without limitation subsequent
         Round(s) of private financing, the Series A Stock holders' purchase
         price (and conversion price) shall be subject to adjustments in
         connection with each Next Round if the offering price per share is
         below $0.37 per share (as adjusted for any stock combination, stock
         dividend, stock split, recapitalization, or other similar transaction
         occurring after the Closing). Each such adjustment shall reduce: (a)
         the conversion price, redemption price, liquidation price and
         conversion price of the Series A Stock, and corresponding Warrant(s) to
         the lowest offering price per share in all Next Rounds. Additional
         shares shall be issued to Series A Stock investors and additional
         Warrant(s) shall be issued to Warrant holders for any adjustments. The
         right to such adjustment shall terminate immediately after the closing
         of a given Next Round with aggregate non-dilutive cash proceeds to the
         Corporation of at least $3,000,000. The following shall not constitute
         a Next Round (provided that the principal purpose of any such issuance
         is for other than equity financing): (i) issuance of securities
         pursuant to the Company's stock-based Employee Compensation Plan(s),
         but so long as the aggregate amount of shares issued or reserved for
         issuance in respect of stock-based Employee Compensation Plans does not
         exceed eighteen percent (18%) of the Corporation's fully-diluted
         shares, (ii) securities issued in connection with any Joint Venture,
         Strategic Alliance, License Agreement, Marketing or Distribution or any
         similar Agreement(s) with respect to the Corporation's business or to
         any person with whom the Corporation has a similar relationship, or
         (iii) securities issued pursuant to, or to finance, the acquisition of
         any business, product technology, know-how whether by asset purchase,
         merger or otherwise.

                  (ii) In case the Corporation shall, prior to the conversion of
         all the Series A Stock: (a) issue Common Stock as a dividend or
         distribution on all shares of Common Stock of the Corporation; (b)
         split or otherwise subdivide its outstanding Common Stock; (c) combine
         the outstanding Common Stock into a smaller number of shares; or (d)
         issue by reclassification of its Common Stock (except in the case of a
         merger, consolidation or sale of all or substantially all of the assets
         of the Corporation as set forth in subparagraph 5(d)(iii) below) any
         shares of the capital stock of the Corporation the Conversion Price in
         effect on the record date for any stock dividend or the effective date
         of any such other event shall be decreased (or increased in the case of
         a reverse stock split) so that the holder of each share of the Series A
         Stock shall thereafter be entitled to receive, upon the conversion of
         such share, the number of shares of Common Stock or other capital stock
         which it would own or be entitled to receive immediately after the
         happening of any of the events mentioned above had such share of the
         Series A Stock been converted immediately prior to the close of
         business on such record date or effective date. The adjustments herein
         provided shall become effective immediately following the record date
         for any such stock dividend or the effective date of any such other
         events. There shall be no reduction in the Conversion Price in the
         event that the Corporation pays a cash dividend.

                                       3

                           (iii) A. In case the Corporation shall issue shares
         of Common Stock or any securities convertible into or exchangeable for
         Common Stock, other than "Excluded Securities" as defined below, for a
         consideration per share (the "Offering Price") less than the Conversion
         Price, the Conversion Price shall be adjusted immediately thereafter so
         that it shall equal the price determined by multiplying the Conversion
         Price in effect immediately prior to the date of issuance by a
         fraction, the numerator of which shall be the number of shares of
         Common Stock outstanding immediately prior to the issuance of such
         additional shares plus the number of shares of Common Stock which the
         aggregate consideration received for the issuance of such additional
         shares would purchase at the Conversion Price in effect immediately
         prior to the date of such issuance, and the denominator of which shall
         be the number of shares of Common Stock outstanding immediately after
         the issuance is made. The provisions of this subparagraph shall not
         apply retroactively to any Series A Stock that has been converted prior
         to the date of adjustment.

                                B. Except as otherwise, in no event shall the
         Conversion Price be increased above the initial Conversion Price, as
         otherwise adjusted pursuant to this Section 5.

                                C. No adjustment in the Conversion Price or the
         number of shares of Common Stock into which a share of Series A Stock
         may be converted shall be required unless such adjustment (plus any
         adjustments not previously made by reason of this subparagraph) would
         require an increase or decrease of at least .5% in the number of shares
         of Common Stock into which each share of the Series A Stock is then
         convertible; provided, however, that any adjustments which are not
         required to be made by reason of this subparagraph shall be carried
         forward and taken into account in any subsequent adjustment. All
         calculations and adjustments shall be made to the nearest cent or to
         the nearest whole share, as the case may be.

                                D. After each adjustment of the Conversion Price
         the Corporation shall promptly prepare a certificate signed by its
         Chief Executive Officer and/or its Chief Financial Officer and/or its
         Secretary and/or Assistant Secretary setting forth the Conversion
         Price, as so adjusted; the number of shares of Common Stock into which
         the Series A Stock may be converted, and a statement of the facts upon
         which such adjustment is based, and such certificate shall forthwith be
         filed with the transfer agent, if any, for the Series A Stock, and the
         Corporation shall cause such a copy of statement to be sent by
         certified mail to each holder of Series A Stock.

                                E. In the case of the issuance of Common Stock
         for cash, the consideration shall be deemed to be the amount of cash
         paid therefor before deducting any reasonable discounts, commissions or
         other expenses allowed, paid or incurred by this Corporation for any
         underwriting or otherwise in connection with the issuance and sale
         thereof.

                                F. In the case of the issuance of the Common
         Stock for any consideration in whole or in part other than cash, the
         consideration other than cash shall be deemed to be the fair value
         thereof as determined in good faith by the Board of Directors.

                                G. The following issuances of Common Stock shall
         be excluded from the adjustments set forth in this Paragraph
         5(d)("Excluded Securities"):

                                    (1) Shares of capital stock issued pursuant
         to a stock dividend or a stock split or other subdivision or
         recombination of shares;

                                    (2) Common Stock issued upon exercise of any
         Warrants, Options or other securities outstanding on the date of the
         closing of the current Note Offering

                                       4

<PAGE>

                                    (3) Securities issued by the Corporation in
         an IPO pursuant to a firm commitment underwriting;

                                    (4) Securities issued to shareholders of any
         entity which merges into the Corporation in proportion to their stock
         holdings of such corporation immediately prior to such merger, upon
         such merger; or

                                    (5) Common Stock or Options or Warrants to
         purchase Common Stock issued to officers, directors or employees of
         and/or to consultants to the Corporation pursuant to any compensation
         agreement, Plan or arrangement or the issuance of Common Stock upon the
         exercise of any such options or Warrants outstanding on the date of the
         closing of the current Note Offering; and

                           (iii) In case of any reclassification or similar
         change of outstanding shares of Common Stock of the Corporation, or in
         case of the consolidation or merger of the Corporation with another
         corporation, or the conveyance of all or substantially all of the
         assets of the Corporation in a transaction in which holders of the
         Common Stock receive shares of stock or other property including cash,
         each share of the Series A Stock shall, after such event and subject to
         the other rights of the Series A Stock as set forth elsewhere herein,
         be convertible only into the number of shares of stock or other
         securities or property, including cash, to which a holder of the number
         of shares of Common Stock of the Corporation deliverable upon
         conversion of such shares of the Series A Stock would have been
         entitled upon such reclassification, change, consolidation, merger or
         conveyance had such share been converted immediately prior to the
         effective date of such event.

                  (e) RESERVATION OF SHARES. The Corporation shall at all times
reserve and keep available, out of its authorized but unissued shares of Common
Stock, or out of shares of Common Stock held in its treasury, solely for the
purpose of effecting the conversion of the shares of the Series A Stock, the
full number of shares of Common Stock deliverable upon the conversion of all
shares of the Series A Stock from time to time outstanding.

                  (f) FRACTIONAL SHARES. No fractional shares or scrip
representing fractional shares of Common Stock shall be issued upon the
conversion of the Series A Stock.

                  (g) TAXES, ETC. The Corporation will pay any taxes that may be
payable in respect of any issue or delivery of shares of Common Stock on
conversion of shares of the Series A Stock. However, the Corporation shall not
be required to pay any tax which may be payable in respect to any transfer
involved in the issue and delivery of shares of Common Stock upon conversion in
a name other than that in which the shares of the Series A Stock so converted
were registered, and no such issue or delivery shall be made unless and until
the person requesting such issue or delivery has paid to the Corporation the
amount of any such tax, or has established, to the satisfaction of the
Corporation, that such tax has been paid.

                  (h) ASSURANCES. The Corporation will not, by amendment of its
Articles of Incorporation, or through any reorganization, recapitalization,
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 o the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 6 and in the taking of all such action as may
be necessary or appropriate in order to protect the conversion rights of the
holder(s) of the Series A Stock against impairment.

<PAGE>

                  (i) REISSUANCE. No shares of Series A Stock which have been
converted to Common Stock shall be reissued by the Corporation, provided,
however, that any such share, upon being converted and canceled, shall be
restored to the status of an authorized but un-issued share of Preferred Stock
without designation as to series, rights or preferences and may thereafter be
issued as a share of Preferred Stock not designated as Series A Stock.

         6. VOTING RIGHTS.

                  (a) The Series A Stock holder(s) shall be entitled to vote on
a "as-if" converted basis and not as a separate class, except as specifically
provided herein or otherwise required by law. Each share of the Series A Stock
shall have the number of votes equal to the number of shares of Common Stock
then issuable upon conversion of such shares of the Series A Stock into Common
Stock.

                  (b) In addition to any other rights provided for herein or by
law, the holders of Series A Stock shall be entitled to vote, together with the
holder(s) of Common Stock as one class, on all matters as to which holders of
Common Stock shall be entitled to vote, in the same manner and with the same
effect a such Common Stock holders. In any such vote each share of Series A
Stock shall entitle the holder thereof to the number of votes per share that
equals the number of whole shares of Common Stock into which each such share of
Series A Stock is then convertible, calculated to the nearest whole share.

                  (c) So long as any shares of the Series A Stock remain
outstanding, the consent of the holder(s) of the then outstanding Series A
Stock, either expressed in writing or at a meeting called for that purpose,
shall be necessary to permit, effect or validate the creation and issuance of
any series of Parity Securities, Preferred Stock, and/or other security of the
Corporation which is senior in Liquidation and/or dividend rights to the Series
A Stock.

                  (d) So long as any shares of the Series A Stock remain
outstanding, the consent of all of the holder(s) of the then outstanding Series
A Stock, either expressed in writing or at a meeting called for that purpose,
shall be necessary to repeal, amend, or otherwise change this Designation and/or
the Articles of Incorporation of the Corporation, in a manner which would alter
or change the powers, preferences, rights, privileges, restrictions and
conditions of the Series A Stock so as to adversely affect the Series A Stock.

                  (e) Each share of the Series A Stock shall entitle the holder
thereof to one (1) vote on all matters to be voted on by the holders of the
Series A Stock, as set forth above.

                  (f) In the event that the holders of the Series A Stock are
required to vote as a class on any other matter, the affirmative vote of all of
the holder(s) of the outstanding shares of Series A Stock shall be required to
approve each such matter to be voted upon, and if any matter is approved by such
requisite percentage of holders of Series A Stock, such matter shall bind all
holders of Series A Stock.

         7. NO PREEMPTIVE RIGHTS. The holder(s) of the Series A Stock shall have
no preemptive rights.

         8. STATUS OF CONVERTED STOCK. In the event any shares of Series A Stock
shall be converted pursuant to Paragraph 5 hereof, the shares so converted shall
be cancelled and shall not be issuable by the Corporation. The Articles of
Incorporation of the Corporation, as amended, may be appropriately amended from
time to time to effect the corresponding reduction in the Corporation's
authorized capital stock.

         9. MISCELLANEOUS.

                  (a) There is no sinking fund with respect to the Series A
Stock.

                  (b) The shares of the Series A Stock shall not have any

other special rights except as set forth above in this Designation and in the
Articles of Incorporation of the Corporation, as amended.

                  (c) The holders of the Series A Stock shall be entitled to

Stock.

                  (d) The holders of the Series A Stock shall be entitled to
nominate either one Director and/or one representative to the Board of Directors
of the Corporation, which Director and/or representative shall be an individual
mutually agreeable to both the Corporation and to the holders of a majority of
the Series A Stock,

                                 FORM OF WARRANT

         (e) "EXERCISE SHARES" shall mean the shares of Common Stock issuable

2.  EXERCISE OF WARRANT.

2.1 EXERCISE PROCEDURES. The rights represented by this Warrant may be exercised
in whole or in part at any time during the Exercise Period, by delivery of the
following to the Company at its address set forth above (or at such other
address as it may designate by notice in writing to the Holder):

         (a) An executed Notice of Exercise in the form attached hereto;

         (b) Payment of the Exercise Price either (i) in cash or by check, or
         (ii) by cancellation of indebtedness; and

         (c) This Warrant.

The date of delivery to the Company of the foregoing items shall be the
effective date of the exercise of this Warrant (the "EFFECTIVE DATE").

Upon the exercise of the rights represented by this Warrant, a certificate or
certificates for the Exercise Shares so purchased, registered in the name of the
Holder or persons identified by the Holder, if the Holder so designates, shall
be issued and delivered to the Holder promptly after the rights represented by
this Warrant shall have been so exercised, together with an amount of cash in
lieu of any fraction of a share as provided in paragraph 6 below. If the Holder
exercises this Warrant in part, this Warrant shall be surrendered by the Holder
to the Company and a new Warrant of the same tenor and for the unexercised
number of Exercise Shares shall be executed by the Company. The Company shall
register the new Warrant in the name of the Holder or in such name or names of
its transferee pursuant to paragraph 8 hereof as may be directed in writing by
the Holder and deliver the new Warrant to the person or persons entitled to
receive the same.

The person in whose name any certificate or certificates for Exercise Shares are
to be issued upon exercise of this Warrant shall be deemed to have become the
holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Exercise Price was made, irrespective of the date
of delivery of such certificate or certificates, except that, if the date of
such surrender and payment is a date when the stock transfer books of the

                                       2

<PAGE>

Company are closed, such person shall be deemed to have become the holder of
such shares at the open of business on the next succeeding date on which the
stock transfer books are open.

2.2 NET EXERCISE. Notwithstanding any provisions herein to the contrary, if the
fair market value of one share of Common Stock is greater than the Exercise
Price (at the date of calculation as set forth below), in lieu of exercising
this Warrant by payment of cash, the Holder may elect to receive shares equal to
the value (as determined below) of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant at the principal office of the Company
together with the properly endorsed Notice of Exercise in which event the
Company shall issue to the Holder a number of shares of Common Stock computed
using the following formula:

       X  =  Y(A-B)
             ------
               A

Where X =         the number of shares of Common Stock to be issued to the
                  Holder

Y =               the number of shares of Common Stock purchasable under the
                  Warrant or, if only a portion of the Warrant is being
                  exercised, the portion of the Warrant being canceled (at the
                  date of such calculation)

A =               the fair market value of one share of the Common Stock (at the
                  date immediately preceding the date on which the Holder
                  satisfied the delivery obligations set forth in Section 2.1)

B =               Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the fair market value of one share of
Common Stock shall be:

         (a) the average daily Market Price (as defined below) for one share of
         Common Stock during the period of the most recent ten (10) Trading
         Days, ending on the last business day before the Effective Date; or

         (b) if no class of Common Stock is then listed or admitted to trading
         on any national securities exchange or quoted in the over-counter
         market, the fair market value shall be the Market Price on the last
         business day before the effective date of exercise of the Warrant.

If the Common Stock is traded on a national securities exchange or admitted to
unlisted trading privileges on such an exchange, or is listed on the National
Market System (the "NATIONAL MARKET SYSTEM") or the Small Cap System (the "SMALL
CAP") of the Nasdaq, the Market Price as of a specified day shall be the last
reported sale price of Common Stock on such exchange or on the National Market
System or the Small Cap on such date or if no such sale is made on such day, the

                                       3

<PAGE>

mean of the closing bid and asked prices for such day on such exchange or on the
National Market System. If the Common Stock is not so listed or admitted to
unlisted trading privileges, the Market Price as of a specified day shall be the
mean of the last bid and asked prices reported on such date (x) by the Nasdaq or
(y) if reports are unavailable under clause (x) above by the National Quotation
Bureau Incorporated. If the Common Stock is not so listed or admitted to
unlisted trading privileges and bid and ask prices are not reported, the Market
Price as of a specified day shall be determined in good faith by the Board of
Directors of the Company. If the Holder shall object to any determination by the
Board of Directors of the Market Price, the Market Price shall be the fair
market value per share of the Common Stock as determined by an independent
appraiser retained by the Holder at its expense and reasonably acceptable to the
Company; provided, however, that if the Market Price as determined by such
appraiser shall differ from the Market Price determined by the Board of
Directors by more than ten percent (10%), the Company shall bear the expense of
such appraiser.

3.  COVENANTS OF THE COMPANY.

3.1 COVENANTS AS TO EXERCISE SHARES. The Company covenants and agrees that all
Exercise Shares that may be issued upon the exercise of the rights represented
by this Warrant will, upon issuance, be validly issued and outstanding, fully
paid and nonassessable, and free and clear from all taxes, liens, security
interests, charges and other encumbrances and restrictions on sale other than as
is provided in Section 5.5(a) of the Purchase Agreement (as defined below). The
Company further covenants and agrees that the Company will at all times during
the Exercise Period, have authorized and reserved, free from preemptive rights,
a sufficient number of shares of its Common Stock to provide for the full
exercise of the rights represented by this Warrant. If at any time during the
Exercise Period the number of authorized but unissued shares of Common Stock
shall not be sufficient to permit the full exercise of this Warrant, the Company
will take such corporate action as is, in the opinion of its counsel, necessary
to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purposes.

3.2 NO IMPAIRMENT. Except and to the extent as waived or consented to by the
Holder, the Company will not, by amendment of its Amended and Restated Articles
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 to be observed or performed hereunder by the Company, but will at all
times in good faith assist in the carrying out of all the provisions of this
Warrant and in the taking of all such action as may be necessary or appropriate
in order to protect the exercise rights of the Holder against impairment.

3.3 NOTICES OF RECORD DATE. In the event of any taking by the Company of a
record of the holders of any class of securities for the purpose of determining
the holders thereof who are entitled to receive any dividend (other than a cash
dividend which is the same as cash dividends paid in previous quarters) or other
distribution, the Company shall mail to the Holder, at least ten (10) days prior
to the date specified herein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend or distribution.

4.  ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF EXERCISE SHARES.

                                       4

<PAGE>

4.1  CERTAIN ADJUSTMENT EVENTS.

         (a) In the event of changes in the outstanding Common Stock after April
         26, 2004 (the "ESCROW DATE") by reason of stock dividends,
         distributions payable in Common Stock, split-ups, recapitalizations,
         reclassifications, combinations or exchanges of shares, separations,
         reorganizations, liquidations, or the like, the number and class of
         shares available under the Warrant in the aggregate and the Exercise
         Price shall be correspondingly adjusted to give the Holder of the
         Warrant, on exercise for the same aggregate Exercise Price, the total
         number, class, and kind of shares as the Holder would have owned had
         the Warrant been exercised prior to the event and had the Holder
         continued to hold such shares until after the event requiring
         adjustment. The form of this Warrant need not be changed because of any
         adjustment in the number of Exercise Shares subject to this Warrant.

         (b) In the event the number of shares of Common Stock issuable upon
         conversion of the Company's Series A Preferred Stock (the "CONVERSION
         SHARES") is increased due to an adjustment pursuant to the terms of the
         Company's Certificate of Designation for the Series A Preferred Stock,
         then the number of shares of Common Stock available under this Warrant
         in the aggregate shall be correspondingly adjusted to give the Holder
         of the Warrant, on exercise for the same aggregate Exercise Price, the
         number of additional shares equivalent to Thirty Percent (30%) of a
         share of Common Stock for each additional Conversion Share such Holder
         is deemed to hold.

4.2  ADDITIONAL SHARES ISSUED BELOW THE EXERCISE PRICE.

         (a) If at any time or from time to time after the Escrow Date, the
         Company issues or sells, or is deemed to have issued or sold,
         Additional Shares of Common Stock (as defined below), other than as a
         dividend or other distribution as provided in Section 4.1 above, and
         other than a subdivision or combination of shares of Common Stock as
         provided in Section 4.1 above, for a price less than the then effective
         Exercise Price, then in each such case, the Exercise Price shall be
         adjusted, as of the opening of business on the date of such issue or
         sale, to a price equal to the Effective Price of such Additional Shares
         of Common Stock. References to Common Stock in this Section 4.2 shall
         mean all shares of Common Stock issued by the Company or deemed to be
         issued pursuant to this Section 4.2. The "EFFECTIVE PRICE" of such
         Additional Shares of Common Stock shall mean the quotient determined by
         dividing the total number of Additional Shares of Common Stock issued
         or sold, or deemed to have been issued or sold, by the Company under
         this Section 4.2, into the Aggregate Consideration (as hereinafter
         defined) received, or deemed to have been received, by the Company for
         such issuance or sale under this Section 4.2 for such shares of
         Additional Stock.

         (b) No adjustment shall be made to the Exercise Price in an amount less
         than one cent per share. Any adjustment otherwise required by this
         Section 4, that is not required to be made due to the preceding
         sentence shall be included in any subsequent adjustment to the Exercise
         Price.

                                       5

<PAGE>

         (c) For purpose of making any adjustment required under this
         Section 4, the Aggregate Consideration received by the Company for any
         issue or sale of securities shall: (i) to the extent it consists of
         cash, be computed at the net amount of cash received by the Company
         after deduction of any underwriting or similar commissions,
         compensation or concessions paid or allowed by the Company in
         connection with such issue or sale but without deduction of any
         expenses payable by the Company, (ii) to the extent it consists of
         property other than cash, be computed at the fair value of that
         property as determined in good faith by the Board of Directors, and
         (iii) if Additional Shares of Common Stock, Convertible Securities (as
         defined below) or rights or options to purchase either Additional
         Shares of Common Stock or Convertible Securities are issued or sold
         together with other stock or securities or other assets of the Company
         for a consideration which covers both, be computed as the portion of
         the consideration so received that may be reasonably determined in good
         faith by the Board of Directors to be allocable to such Additional
         Shares of Common Stock, Convertible Securities or rights or options
         (the "AGGREGATE CONSIDERATION").

         (d) For the purpose of the adjustment required under this Section 4.2,
         if the Company issues or sells (i) stock or other securities
         convertible into Additional Shares of Common Stock (such convertible
         stock or securities being herein referred to as "CONVERTIBLE
         SECURITIES") or (ii) rights or options for the purchase of Additional
         Shares of Common Stock or Convertible Securities, in each case the
         Company shall be deemed to have issued at the time of the issuance of
         such rights or options or Convertible Securities the maximum number of
         Additional Shares of Common Stock issuable upon exercise or conversion
         thereof and to have received as consideration for the issuance of such
         shares an amount equal to the total amount of the consideration, if
         any, received by the Company for the issuance of such rights or options
         or Convertible Securities plus, in the case of such rights or options,
         the minimum amounts of consideration, if any, payable to the Company
         upon the exercise of such rights or options; and in the case of
         Convertible Securities, the minimum amounts of consideration, if any,
         payable to the Company upon the conversion thereof (other than by
         cancellation of liabilities or obligations evidenced by such
         Convertible Securities); PROVIDED that if the minimum amounts of such
         consideration cannot be ascertained, but are a function of antidilution
         or similar protective clauses, the Company shall be deemed to have
         received the minimum amounts of consideration without reference to such
         clauses.

                  (i) If the minimum amount of consideration payable to the
                  Company upon the exercise or conversion of rights, options or
                  Convertible Securities is reduced over time or on the
                  occurrence or non-occurrence of specified events other than by
                  reason of antidilution adjustments for which a corresponding
                  adjustment is made hereunder, the Effective Price shall be
                  recalculated using the figure to which such minimum amount of
                  consideration is reduced; PROVIDED FURTHER, that if the
                  minimum amount of consideration payable to the Company upon
                  the exercise or conversion of such rights, options or
                  Convertible Securities is subsequently increased, the
                  Effective Price shall be again recalculated using the
                  increased minimum amount of consideration payable to the
                  Company upon the exercise or conversion of such rights,
                  options or Convertible Securities.

                                       6

<PAGE>

                  (ii) No further adjustment of the Exercise Price, as adjusted
                  upon the issuance of such rights, options or Convertible
                  Securities, shall be made as a result of the actual issuance
                  of Additional Shares of Common Stock or the exercise of any
                  such rights or options or the conversion of any such
                  Convertible Securities. If any such rights or options or the
                  conversion privilege represented by any such Convertible
                  Securities shall expire without having been exercised, the
                  Exercise Price as adjusted upon the issuance of such rights,
                  options or Convertible Securities shall be readjusted to the
                  Exercise Price which would have been in effect had an
                  adjustment been made on the basis that the only Additional
                  Shares of Common Stock so issued were the Additional Shares of
                  Common Stock, if any, actually issued or sold on the exercise
                  of such rights or options or rights of conversion of such
                  Convertible Securities, and such Additional Shares of Common
                  Stock, if any, were issued or sold for the consideration
                  actually received by the Company upon such exercise, plus the
                  consideration, if any, actually received by the Company for
                  the granting of all such rights or options, whether or not
                  exercised, plus the consideration received for issuing or
                  selling the Convertible Securities actually converted, plus
                  the consideration, if any, actually received by the Company
                  (other than by cancellation of liabilities or obligations
                  evidenced by such Convertible Securities) on the conversion of
                  such Convertible Securities, PROVIDED that such readjustment
                  shall not apply to prior exercises of the Warrant or portions
                  thereof.

         (e) "ADDITIONAL SHARES OF COMMON STOCK" DEFINED. For the purpose of
         making any adjustment to the Exercise Price required under this Section
         4.2, "ADDITIONAL SHARES OF COMMON STOCK" shall mean all shares of
         Common Stock issued by the Company or deemed to be issued pursuant to
         this Section 4.2, whether or not subsequently reacquired or retired by
         the Company in connection with any new investments in the Company
         subsequent to the Closing, including without limitation subsequent
         rounds of private financing, other than: (i) shares of Common Stock
         issued upon conversion of the Series A Preferred Stock; (ii) issuance
         of securities pursuant to the Company's stock-based employee
         compensation plans, so long as the aggregate amount of shares issued or
         reserved for issuance in respect of stock-based employee compensation
         plans never exceeds 18% of the Company's fully-diluted shares; (iii)
         securities issued in connection with any joint venture, strategic
         alliance, license agreement, marketing or other distribution agreement
         with respect to the Company's business or products or to any person
         with whom the Company has a similar relationship; (iv) securities
         issued pursuant to, or to finance, the acquisition of any business,
         product, technology, know-how whether by asset purchase, merger or
         otherwise.

4.3 EXTRAORDINARY DIVIDEND. In case the Company shall fix a record date for the
making of a distribution to holders of Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, assets or
other property (other than dividends payable in Common Stock or rights, options
or warrants referred to in, and for which an adjustment is made pursuant to,
Section 4.1 hereof), the Exercise Price to be in effect after such record date
shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the

                                       7

<PAGE>

Current Market Price per share of Common Stock on such record date, less the
fair market value of the portion of the assets, other property or evidence of
indebtedness so to be distributed which is applicable to one share of Common
Stock, and the denominator of which shall be such Current Market Price per share
of Common Stock. Such fair market value shall be determined by the Board of
Directors of the Company; PROVIDED that if the Holder shall object to any such
determination, the Holder shall retain an independent appraiser reasonably
satisfactory to the Company to determine such fair market value; provided,
however, that if the Current Market Price as determined by such appraiser shall
differ from the Current Market Price determined by the Board of Directors by
more than ten percent (10%), the Company shall bear the expense of such
appraiser. Such adjustments shall be made successively whenever such a record
date is fixed; and in the event that such distribution is not so made, the
Exercise Price shall again be adjusted to be the Exercise Price which would then
be in effect if such record date had not been fixed.

4.4 THIRD PARTY TENDER OFFER. If at any time or from time to time after the
Escrow Date, a tender or exchange offer is made by a person other than the
Company or one of its affiliates for an amount that increases the offeror's
ownership of Common Stock to more than twenty-five percent (25%) of the Common
Stock outstanding and shall involve the payment by such person of consideration
per share of Common Stock having a fair market value (as determined by the Board
of Directors and described in a resolution of the Board of Directors) that as of
the last time (the "OFFER EXPIRATION TIME") tenders or exchanges may be made
pursuant to such tender or exchange offer (as it shall have been amended) that
exceeds the Current Market Price of the Common Stock on the Trading Day next
succeeding the Offer Expiration Time, and in which, as of the Offer Expiration
Time the Board of Directors is not recommending rejection of the offer, the
Exercise Price shall be reduced so that the same shall equal the price
determined by multiplying the Exercise Price in effect immediately prior to the
Offer Expiration Time by a fraction the numerator of which shall be the number
of shares of Common Stock outstanding (including any tendered or exchanges
shares) at the Offer Expiration Time multiplied by the Current Market Price of
the Common Stock on the Trading Day next succeeding the Offer Expiration Time
and the denominator of which shall be the sum of (a) the fair market value of
the aggregate consideration payable to shareholders based on the acceptance (up
to an maximum specified in the terms of the tender or exchange offer) of all
shares validly tendered or exchanged and not withdrawn as of the Offer
Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "ACCEPTED PURCHASED SHARES") and (b) the product of the
number of shares of Common Stock outstanding (less any Accepted Purchased
Shares) at the Offer Expiration Time and the Current Market Price of the Common
Stock on the Trading Day next succeeding the Offer Expiration Time, such
reduction to become effective immediately prior to the opening of business on
the Trading Day following the Offer Expiration Time. In the event that the
offeror is obligated to purchase shares pursuant to any such tender or exchange
offer, but such person is permanently prevented by applicable law from effecting
any such purchase or all such purchases are rescinded, the Exercise Price shall
again be adjusted to be the Exercise Price that would be then in effect if such
tender or exchange offer had not been made.

4.5 ORGANIC CHANGES. If any recapitalization, reclassification or reorganization
of the capital stock of the Company, or any consolidation or merger of the
Company with another corporation, or the sale of all or substantially all of its
assets or other transaction shall be effected in such a way that holders of the

Company's Common Stock shall be entitled to receive stock, securities, or other
assets or property (an "ORGANIC CHANGE"), then, as a condition of such Organic
Change, lawful and adequate provisions shall be made by the Company whereby the
Holder hereof shall thereafter have the right to purchase and receive (in lieu
of the shares of the Common Stock of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented hereby)
such shares of stock, securities or other assets or property as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of shares of such stock immediately
theretofore purchasable and receivable upon the exercise of the rights
represented hereby assuming (a) such holder of Common Stock is not a person with
which the Company consolidated or into which the Company merged or which merged
into the Company or to which such sale or transfer was made, as the case may be
(the "CONSTITUENT PERSON"), or an affiliate of a Constituent Person and (b) in
the case of a consolidation, merger, sale or transfer which includes an election
as to the consideration to be received by the holders, such holders of Common
Stock failed to exercise its rights of election, as to the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or other transfer (PROVIDED that if the kind or amount of securities, cash
and other property receivable upon such consolidation, merger, sale or transfer
is not the same for each share of Common Stock held immediately prior to such
consolidation, merger, sale or transfer by other than the Constituent Person or
an affiliate thereof and in respect of which such rights of election shall not
have been exercised (the "NON-ELECTING SHARE"), then for purposes of this
paragraph the kind and amount of securities, cash and other property receivable
upon such consolidation, merger, sale or transfer for each Non-Electing Share
shall be deemed to be the kind and amount so receivable per share by a plurality
of the Non-Electing Shares. In the event of any Organic Change, appropriate
provision shall be made by the Company with respect to the rights and interests
of the Holder of this Warrant to the end that the provisions hereof (including,
without limitation, provisions for adjustments of the Exercise Price and of the
number of shares purchasable and receivable upon the exercise of this Warrant)
shall thereafter be applicable, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise hereof.

4.6 CERTIFICATE AS TO ADJUSTMENT--NOTICE BY THE COMPANY. In each case of an
adjustment or readjustment of the Exercise Price, the Company, at its expense,
shall compute such adjustment or readjustment in accordance with the provisions
hereof and prepare a certificate showing such adjustment or readjustment, and
shall mail such certificate, by first class mail, postage prepaid, to the Holder
at the Holder's address as shown in the Company's books. The certificate shall
set forth such adjustment or readjustment, showing in detail the facts upon
which such adjustment or readjustment is based, including a statement of (a) the
consideration received or deemed to be received by the Company for any
Additional Shares of Common Stock issued or sold or deemed to have been issued
or sold, if applicable, (b) the number of Additional Shares of Common Stock, if
applicable, and (c) the type and amount, if any, of other property which at the
time would be received upon exercise of the Warrant.

5.  REPRESENTATIONS OF HOLDER.

                                       9

<PAGE>

5.1 ACQUISITION OF WARRANT FOR PERSONAL ACCOUNT. The Holder represents and
warrants that it is acquiring the Warrant solely for its account for investment
and not with a view to or for sale or distribution of said Warrant or any part
thereof. The Holder also represents that the entire legal and beneficial
interests of the Warrant and Exercise Shares the Holder is acquiring are being
acquired for, and will be held for, its account only. 5.2 SECURITIES ARE NOT
REGISTERED.

         (a) The Holder understands that the Warrant and the Exercise Shares
         have not been registered under the Securities Act of 1933, as amended
         (the "Act") on the basis that no distribution or public offering of the
         stock of the Company is to be effected. The Holder realizes that the
         basis for the exemption may not be present if, notwithstanding its
         representations, the Holder has a present intention of acquiring the
         securities for a fixed or determinable period in the future, selling
         (in connection with a distribution or otherwise), granting any
         participation in, or otherwise distributing the securities. The Holder
         has no such present intention.

         (b) The Holder recognizes that the Warrant and the Exercise Shares must
         be held indefinitely unless they are subsequently registered under the
         Act or an exemption from such registration is available. The Holder
         recognizes that the Company has no obligation to register the Warrant
         or to comply with any exemption from such registration.

         (c) The Holder is aware that neither the Warrant nor the Exercise
         Shares may be sold pursuant to Rule 144 adopted under the Act unless
         certain conditions are met, including, among other things, the
         existence of a public market for the shares, the availability of
         certain current public information about the Company, the resale
         following the required holding period under Rule 144 and the number of
         shares being sold during any three month period not exceeding specified
         limitations.

    5.3  DISPOSITION OF WARRANT AND EXERCISE SHARES.

         (a) The Holder further agrees not to make any disposition of all or any
         part of the Warrant or Exercise Shares in any event unless and until
         Section 5.5 of the Unit Purchase Agreement by and between the Company
         and the Holder dated April 26, 2004 ("PURCHASE AGREEMENT") has been
         complied with in all respects and unless and until:

                  (i) The Company shall have received a letter secured by the
                  Holder from the Securities and Exchange Commission (the
                  "COMMISSION") stating that no action will be recommended to
                  the Commission with respect to the proposed disposition; or

                  (ii) There is then in effect a registration statement under
                  the Act covering such proposed disposition and such
                  disposition is made in accordance with said registration
                  statement; or

                  (iii) The Holder shall have notified the Company of the
                  proposed disposition and shall have furnished the Company with
                  a detailed statement of the circumstances surrounding the
                  proposed disposition or with a Form 144 if the sale is being
                  made pursuant to Rule 144 of the Securities Act, and if
                  reasonably requested by the Company and the sale is not being

                                       10

<PAGE>

                  made pursuant to Rule 144 of the Securities Act, the Holder
                  shall have furnished the Company with an opinion of counsel,
                  reasonably satisfactory to the Company, for the Holder to the
                  effect that such disposition will not require registration of
                  such Warrant or Exercise Shares under the Act or any
                  applicable state securities laws.

         (b) The Holder understands and agrees that all certificates evidencing
         the shares to be issued to the Holder may bear the following legend:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE,
         PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
         STATEMENT AS TO THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL
         SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of
this Warrant as a consequence of any adjustment pursuant hereto. All Exercise
Shares (including fractions) issuable upon exercise of this Warrant may be
aggregated for purposes of determining whether the exercise would result in the
issuance of any fractional share. If, after aggregation, the exercise would
result in the issuance of a fractional share, the Company shall, in lieu of
issuance of any fractional share, pay the Holder otherwise entitled to such
fraction a sum in cash equal to the product resulting from multiplying the then
current fair market value (as determined in Section 2.2) of an Exercise Share by
such fraction.

7. NO SHAREHOLDER RIGHTS. This Warrant in and of itself shall not entitle the
Holder to any voting rights or other rights as a shareholder of the Company.

8. TRANSFER OF WARRANT. Subject to applicable laws and the restrictions on
transfer set forth in the Purchase Agreement pursuant to which this Warrant was
issued, this Warrant and all rights hereunder are transferable at any time in
whole or from time to time in part, including as fractions of a warrant, by the
Holder in person or by duly authorized attorney, upon delivery of this Warrant
and the form of assignment attached hereto to any transferee designated by
Holder. The transferee shall sign an investment letter in form and substance
satisfactory to the Company (in the exercise of its reasonable discretion). Upon
surrender of this Warrant to the Company, together with the attached Assignment
Form duly executed, the Company shall, without charge, execute and deliver a new
Warrant in the name of the assignee or assignees named in such instrument of
assignment and, if the Holder's entire interest is not being assigned, in the
name of the Holder and this Warrant shall promptly be canceled.

9. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost,
stolen, mutilated or destroyed, the Company shall, on such terms as to indemnity
or otherwise as it may reasonably impose (which shall, in the case of a
mutilated Warrant, include the surrender thereof), issue a new Warrant of like
denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed.
Any such new Warrant shall constitute an original contractual obligation of the
Company, whether or not the allegedly lost, stolen, mutilated or destroyed
Warrant shall be at any time enforceable by anyone.

10. NOTICES, ETC. All notices, requests, consents and other communications
hereunder shall be in writing, shall be sent by facsimile or mailed by first
class registered or certified airmail, or nationally recognized overnight
express courier postage prepaid, and shall be deemed given when so sent by
facsimile or mailed and shall be delivered as follows:

         (b) if to the Holder, at the Holder's address as specified in the
         Purchase Agreement, or at such other address or addresses as may have
         been furnished to the Company in writing.

11. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute
acceptance of and agreement to all of the terms and conditions contained herein.

12. AMENDMENTS; WAIVERS. Any provision of this Warrant may be amended or waived
if, and only if, such amendment or waiver is in writing and signed, in the case
of an amendment, by the Holder and the Company, or in the case of a waiver, by
the party against whom waiver is to be effective. No failure or delay by either
party in exercising any right, power or privilege hereunder shall operate as a
waiver thereof nor shall any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein provided shall be cumulative and not
exclusive of any rights or remedies provided by law.

13. FRACTIONAL WARRANTS. The Company may sell or issue, and Holders may hold,
own or transfer, fractions of warrants. Nothing in this Warrant shall prevent or
restrict the application of the provisions of this Warrant to fractions of a
warrant. Notwithstanding the foregoing, the Company will not issue fractional
shares upon the exercise of this Warrant, as provided in Section 6 hereof.

14. GOVERNING LAW. This Warrant and all rights, obligations and liabilities
hereunder shall be governed by the laws of the State of Florida.
