                           MOLECULAR DIAGNOSTICS, INC.

                          COMMON STOCK PURCHASE WARRANT

Warrant                                                         ________ shares

                    Original Issue Date: _____________, 2004

      THIS CERTIFIES THAT, FOR VALUE RECEIVED, _______________ or its registered
assigns ("HOLDER") is entitled to purchase, on the terms and conditions
hereinafter set forth, at any time or from time to time from the date hereof
until 5:00 p.m., Eastern Time, on fifth anniversary of the Original Issue Date
set forth above, or if such date is not a day on which the Company (as
hereinafter defined) is open for business, then the next succeeding day on which
the Company is open for business (such date is the "EXPIRATION DATE"), but not
thereafter, to purchase up to ____________ (______) shares of the Common Stock,
$.001 par value (the "COMMON Stock"), of Molecular Diagnostics, Inc., a Delaware
corporation (the "COMPANY"), at a purchase price of fifteen cents ($0.15) per
share (the "EXERCISE PRICE"), such number of shares and Exercise Price being
subject to adjustment upon the occurrence of the contingencies set forth in this
Warrant. Each share of Common Stock as to which this Warrant is exercisable is a
"WARRANT SHARE" and all such shares are collectively referred to as the "WARRANT
SHARES."

      SECTION 1. EXERCISE OF WARRANT; CONVERSION OF WARRANT.

      (a) Subject to filing the Certificate of Amendment as set forth in Section
3 of the Subscription Agreement, of even date herewith, this Warrant may, at the
option of Holder, be exercised in whole or in part from time to time by delivery
to the Company at its principal office, Attention: President, on or before 5:00
p.m., Eastern Time, on the Expiration Date, (i) a written notice of such
Holder's election to exercise this Warrant (the "EXERCISE NOTICE"), which notice
may be in the form of the Notice of Exercise attached hereto, properly executed
and completed by Holder or an authorized officer thereof, (ii) payment for the
Warrant Shares ("Payment"), as further described in Section 1(b), below, AND
(iii) this Warrant (the items specified in (i), (ii), and (iii) are collectively
the "EXERCISE MATERIALS").

      (b) Payment may be made either in (i) a check payable to the order of the
Company, in an amount equal to the product of the Exercise Price MULTIPLIED BY
the number of Warrant Shares specified in the Exercise Notice, (ii) by delivery
of Warrants, Common Stock and/or Common Stock receivable upon exercise of the
Warrants in accordance with Section 1(c) below, or (iii) by a combination of any
of the foregoing methods) for the number of Common Shares specified in such form


<PAGE>

(as such exercise number shall be adjusted to reflect any adjustment in the
total number of shares of Common Stock issuable to the holder per the terms of
this Warrant) and the holder shall thereupon be entitled to receive the number
of duly authorized, validly issued, fully-paid and non-assessable shares of
Common Stock (or Other Securities) determined as provided herein.

      (c) Notwithstanding any provisions herein to the contrary, if the Fair
Market Value of one share of Common Stock is greater than the Purchase Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash the holder may elect to receive shares equal to the value (as
determined below) of this Warrant (or the portion thereof being cancelled) by
surrender of this Warrant at the principal office of the Company together with
the properly endorsed Subscription Form in which event the Company shall issue
to the holder a number of shares of Common Stock computed using the following
formula:

<TABLE>
<CAPTION>
                           X=Y (A-B)
                                 A
                  <S>      <C>      <C>
                  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 exercised
                                    (at the date of such calculation)

                           A=       the Fair Market Value of one share of the
                                    Company's Common Stock (at the date of such
                                    calculation)

                           B=       Purchase Price (as adjusted to the date of such calculation)
</TABLE>


      (d) Anything contained herein to the contrary notwithstanding, the Holder,
at his option, may exercise the Warrants, in whole or in part, during the
Exercise Term by delivering to the Company a confirmation slip issued by a
brokerage firm that is a member of the National Association of Securities
Dealers, Inc. with respect to the sale of those number of Warrant Shares for
which the Warrants are being exercised, and, in such case, the Company shall
deliver certificates representing such Warrant Shares on settlement date at the
office of the Company's stock transfer agent against payment for such Warrant
Shares by such brokerage firm or its clearing broker, made payable to the
Company or made payable to the order of the Holder and endorsed by the Holder to
the Company.

      (e) As promptly as practicable, and in any event within two (2) business
days after its receipt of the Exercise Materials, Company shall execute or cause
to be executed and delivered to Holder a certificate or certificates
representing the number of Warrant Shares specified in the Exercise Notice,
together with cash in lieu of any fraction of a share, and if this Warrant is
partially exercised, a new warrant on the same terms for the unexercised balance
of the Warrant Shares. The stock certificate or certificates shall be registered
in the name of Holder or such other name or names as shall be designated in the
Exercise Notice. The date on which the Warrant shall be deemed to have been
exercised (the "EFFECTIVE DATE"), and the date the person in whose name any
certificate evidencing the Common Stock issued upon the exercise hereof is
issued shall be deemed to have become the holder of record of such shares, shall
be the date the Company receives the Exercise Materials, irrespective of the
date of delivery of a certificate or certificates evidencing the Common Stock
issued upon the exercise or conversion hereof, PROVIDED, HOWEVER, that if the
Exercise Materials are received by the Company on a date on which the stock

<PAGE>

transfer books of the Company are closed, the Effective Date shall be the next
succeeding date on which the stock transfer books are open. All shares of Common
Stock issued upon the exercise or conversion of this Warrant will, upon
issuance, be fully paid and nonassessable and free from all taxes, liens, and
charges with respect thereto.

      SECTION 2. ADJUSTMENTS TO WARRANT SHARES. The number of Warrant Shares
issuable upon the exercise hereof shall be subject to adjustment as follows:

            (a) In the event the Company is a party to a consolidation, share
      exchange, or merger, or the sale of all or substantially all of the assets
      of the Company to, any person, or in the case of any consolidation or
      merger of another corporation into the Company in which the Company is the
      surviving corporation, and in which there is a reclassification or change
      of the shares of Common Stock of the Company, this Warrant shall after
      such consolidation, share exchange, merger, or sale be exercisable for the
      kind and number of securities or amount and kind of property of the
      Company or the corporation or other entity resulting from such share
      exchange, merger, or consolidation, or to which such sale shall be made,
      as the case may be (the "SUCCESSOR COMPANY"), to which a holder of the
      number of shares of Common Stock deliverable upon the exercise
      (immediately prior to the time of such consolidation, share exchange,
      merger, or sale) of this Warrant would have been entitled upon such
      consolidation, share exchange, merger, or sale; and in any such case
      appropriate adjustments shall be made in the application of the provisions
      set forth herein with respect to the rights and interests of Holder, such
      that the provisions set forth herein shall thereafter correspondingly be
      made applicable, as nearly as may reasonably be, in relation to the number
      and kind of securities or the type and amount of property thereafter
      deliverable upon the exercise of this Warrant. The above provisions shall
      similarly apply to successive consolidations, share exchanges, mergers,
      and sales. Any adjustment required by this Section 2 (a) because of a
      consolidation, share exchange, merger, or sale shall be set forth in an
      undertaking delivered to Holder and executed by the Successor Company
      which provides that Holder shall have the right to exercise this Warrant
      for the kind and number of securities or amount and kind of property of
      the Successor Company or to which the holder of a number of shares of
      Common Stock deliverable upon exercise (immediately prior to the time of
      such consolidation, share exchange, merger, or sale) of this Warrant would
      have been entitled upon such consolidation, share exchange, merger, or
      sale. Such undertaking shall also provide for future adjustments to the
      number of Warrant Shares and the Exercise Price in accordance with the
      provisions set forth in Section 2 hereof.

            (b) In the event the Company should at any time, or from time to
      time after the Original Issue Date, fix a record date for the effectuation
      of a stock split or subdivision of the outstanding shares of Common Stock
      or the determination of holders of Common Stock entitled to receive a
      dividend or other distribution payable in additional shares of Common
      Stock, or securities or rights convertible into, or entitling the holder
      thereof to receive directly or indirectly, additional shares of Common
      Stock (hereinafter referred to as "COMMON STOCK EQUIVALENTS") without
      payment of any consideration by such holder for the additional shares of
      Common Stock or the Common Stock Equivalents (including the additional
      shares of Common Stock issuable upon exercise or exercise thereof), then,
      as of such record date (or the date of such dividend, distribution, split,
      or subdivision if no record date is fixed), the number of Warrant Shares
      issuable upon the exercise hereof shall be proportionately increased and
      the Exercise Price shall be appropriately decreased by the same proportion
      as the increase in the number of outstanding Common Stock Equivalents of
      the Company resulting from the dividend, distribution, split, or
      subdivision. Notwithstanding the preceding sentence, no adjustment shall
      be made to decrease the Exercise Price below $.001 per Share.


<PAGE>

            (c) In the event the Company should at any time or from time to time
      after the Original Issue Date, fix a record date for the effectuation of a
      reverse stock split, or a transaction having a similar effect on the
      number of outstanding shares of Common Stock of the Company, then, as of
      such record date (or the date of such reverse stock split or similar
      transaction if no record date is fixed), the number of Warrant Shares
      issuable upon the exercise hereof shall be proportionately decreased and
      the Exercise Price shall be appropriately increased by the same proportion
      as the decrease of the number of outstanding Common Stock Equivalents
      resulting from the reverse stock split or similar transaction.

            (d) In the event the Company should at any time or from time to time
      after the Original Issue Date, fix a record date for a reclassification of
      its Common Stock, then, as of such record date (or the date of the
      reclassification if no record date is set), this Warrant shall thereafter
      be convertible into such number and kind of securities as would have been
      issuable as the result of such reclassification to a holder of a number of
      shares of Common Stock equal to the number of Warrant Shares issuable upon
      exercise of this Warrant immediately prior to such reclassification, and
      the Exercise Price shall be unchanged.

            (e) The Company will not, by amendment of its Certificate of
      Incorporation or through reorganization, consolidation, merger,
      dissolution, issue, or sale of securities, sale of assets or any other
      voluntary action, void or seek to avoid the observance or performance of
      any of the terms of the 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
      actions as may be necessary or appropriate in order to protect the rights
      of Holder against dilution or other impairment. Without limiting the
      generality of the foregoing, the Company (x) will not create a par value
      of any share of stock receivable upon the exercise of the Warrant above
      the amount payable therefor upon such exercise, and (y) will take all such
      action as may be necessary or appropriate in order that the Company may
      validly and legally issue fully paid and non-assessable shares upon the
      exercise of the Warrant.

            (f) When any adjustment is required to be made in the number or kind
      of shares purchasable upon exercise of the Warrant, or in the Exercise
      Price, the Company shall promptly notify Holder of such event and of the
      number of shares of Common Stock or other securities or property
      thereafter purchasable upon exercise of the Warrants and of the Exercise
      Price, together with the computation resulting in such adjustment.

            (g) The Company covenants and agrees that all Warrant Shares which
      may be issued will, upon issuance, be validly issued, fully paid, and
      non-assessable. The Company further covenants and agrees that the Company
      will at all times have authorized and reserved, free from preemptive
      rights, a sufficient number of shares of its Common Stock to provide for
      the exercise of the Warrant in full.

      SECTION 3. NO STOCKHOLDER RIGHTS. This Warrant shall not entitle Holder
hereof to any voting rights or other rights as a stockholder of the Company.

      SECTION 4. TRANSFER OF SECURITIES.

            (a) This Warrant and the Warrant Shares and any shares of capital
      stock received in respect thereof, whether by reason of a stock split or
      share reclassification thereof, a stock dividend thereon, or otherwise,
      shall not be transferable except upon compliance with the provisions of
      the Securities Act of 1933, as amended (the "SECURITIES ACT") and

<PAGE>

      applicable state securities laws with respect to the transfer of such
      securities. The Holder, by acceptance of this Warrant, agrees to be bound
      by the provisions of Section 4 hereof and to indemnify and hold harmless
      the Company against any loss or liability arising from the disposition of
      this Warrant or the Warrant Shares issuable upon exercise hereof or any
      interest in either thereof in violation of the provisions of this Warrant.

      (b) Each certificate for the Warrant Shares and any shares of capital
stock received in respect thereof, whether by reason of a stock split or share
reclassification thereof, a stock dividend thereon or otherwise, and each
certificate for any such securities issued to subsequent transferees of any such
certificate shall (unless otherwise permitted by the provisions hereof) be
stamped or otherwise imprinted with a legend in substantially the following
form:


      "neither this warrant nor the shares of Common Stock issuable upon
      exercise hereof have been registered under the securities act of 1933, as
      amended, or any applicable state securities law and neither may be sold or
      otherwise transferred until (i) a registration statement under such
      securities act and such applicable state securities laws shall have become
      effective with regard thereto, or (ii) the company shall have received a
      written opinion of counsel acceptable to the company to the effect that
      registration under such securities act and such applicable state
      securities laws is not required in connection with such proposed
      transfer."

      SECTION 5. REGISTRATION.

      All Warrant Shares are subject to the rights and privileges granted to the
participants in the private placement offering pursuant to which this Warrant
was issued.

      SECTION 5. MISCELLANEOUS.

            (a) The terms of this Warrant shall be binding upon and shall inure
to the benefit of any successors or permitted assigns of the Company and Holder.

            (b) Except as otherwise provided herein, this Warrant and all rights
hereunder are transferable by the registered holder hereof in person or by duly
authorized attorney on the books of the Company upon surrender of this Warrant,
properly endorsed, to the Company. The Company may deem and treat the registered
holder of this Warrant at any time as the absolute owner hereof for all purposes
and shall not be affected by any notice to the contrary.

            (c) Notwithstanding any provision herein to the contrary, Holder may
not exercise, sell, transfer, or otherwise assign this Warrant unless the
Company is provided with an opinion of counsel satisfactory in form and
substance to the Company, to the effect that such exercise, sale, transfer, or
assignment would not violate the Securities Act or applicable state securities
laws.

            (d) This Warrant may be divided into separate warrants covering one
share of Common Stock or any whole multiple thereof, for the total number of
shares of Common Stock then subject to this Warrant at any time, or from time to
time, upon the request of the registered holder of this Warrant and the
surrender of the same to the Company for such purpose. Such subdivided Warrants
shall be issued promptly by the Company following any such request and shall be
of the same form and tenor as this Warrant, except for any requested change in
the name of the registered holder stated herein.

            (e) Any notices, consents, waivers, or other communications required
or permitted to be given under the terms of this Warrant must be in writing and
will be deemed to have been delivered (a) upon receipt, when delivered
personally, (b) upon receipt, when sent by facsimile, PROVIDED a copy is mailed

<PAGE>

by U.S. certified mail, return receipt requested, (c) three (3) days after being
sent by U.S. certified mail, return receipt requested, or (d) one (1) day after
deposit with a nationally recognized overnight delivery service, in each case
properly addressed to the party to receive the same.

      If to Holder, to the registered address of Holder appearing on the books
of the Company. Each party shall provide five (5) days prior written notice to
the other party of any change in address, which change shall not be effective
until actual receipt thereof

            (f) This Warrant shall be construed and enforced in accordance with
the laws of the State of Illinois. The Company and the Holder hereby consent to
the jurisdiction of the Courts of the State of Illinois and the United States
District Courts situated therein in connection with any action concerning the
provisions of this Note instituted by the Holder against the Company.
