                       INVERNESS MEDICAL TECHNOLOGY, INC.
                          COMMON STOCK PURCHASE WARRANT

No. of Shares:                                        Date:              , 2000

                     The Transferability of this Warrant is
                       Restricted as Provided in Article 3


         For good and valuable consideration, the receipt of which is hereby
acknowledged, INVERNESS MEDICAL TECHNOLOGY, INC., a Delaware corporation (the
"Company") hereby grants the right to purchase, until the tenth anniversary of
the date hereof, up to _____ fully paid and non-assessable shares (the "Warrant
Shares") of the Company's Common Stock, $.001 par value ("Common Stock").

         This Warrant is exercisable at a price of $______ per share of Common
Stock issuable hereunder (the "Exercise Price") payable in cash or by certified
or official bank check in Boston Clearing House funds. Upon the undersigned's
surrender of this Warrant with the annexed Subscription Form duly executed,
together with payment of the Exercise Price for the shares of Common Stock being
purchased, at the Company's principal executive offices (currently located at
200 Prospect Street, Waltham, Massachusetts 02453) the undersigned shall be
entitled to receive a certificate or certificates for the shares of Common Stock
so purchased.

1.       EXERCISE OF WARRANT.

         The purchase rights represented by this Warrant are exercisable at the
option of the undersigned, in whole or in part (but not as to fractional shares
of the Common Stock), during any period in which this Warrant may be exercised
as set forth above. In the case of the purchase of less than all the shares of
Common Stock purchasable under this Warrant, the Company shall cancel this
Warrant upon the surrender hereof and shall execute and deliver a new Warrant of
like tenor for the balance of the shares of Common Stock purchasable hereunder.

2.       ISSUANCE OF STOCK CERTIFICATES.



<PAGE>


         The issuance of certificates for shares of Common Stock upon the
exercise of this Warrant shall be made without charge to the undersigned
including, without limitation, any tax which may be payable in respect thereof,
and such certificates shall (subject to the provisions of Article 3 hereof) be
issued in the name of, or in such names as may be directed by, the undersigned;
provided, however, that the Company shall not be required to pay any tax which
may be due with respect to any transfer involved in the issuance and delivery of
any such certificate in a name other than that of the undersigned, and the
Company shall not be required to issue or deliver such certificates unless or
until the person or persons requesting the issuance thereof shall have paid to
the Company the amount of such tax or shall have established to the satisfaction
of the Company that such tax has been paid.

3.       RESTRICTION ON TRANSFER OF WARRANT.

         The undersigned as holder of this Warrant, by its acceptance hereof,
covenants and agrees that this Warrant is being acquired as an investment and
not with a view to the distribution thereof, and that the Warrant will not be
sold, transferred, assigned, hypothecated or otherwise disposed of except as
permitted by the Securities Purchase Agreement pursuant to which this Warrant
was issued.

4.       REPLACEMENT OF WARRANT.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant, and, in case of
loss, theft or destruction, of indemnity or security reasonably satisfactory to
the Company, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of this Warrant, if
mutilated, the Company will make and deliver a new Warrant of like tenor, in
lieu of this warrant.

5.       ADJUSTMENTS IN EXERCISE PRICE.

         In the event the Company: (i) pays a dividend in Common Stock or makes
a distribution in Common Stock, (ii) subdivides its outstanding Common Stock
into a greater number of shares, (iii) combines its outstanding Common Stock
into a smaller number of shares or (iv) increases or decreases the number of
shares of Common Stock outstanding by reclassification of its Common Stock
(including a recapitalization in connection with a consolidation or merger in
which the Company is the continuing corporation), then (1) the Exercise Price on
the record date of such division or distribution or the effective date of such
action shall be adjusted by multiplying such Exercise Price by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately before such event and the denominator of which is the number of
shares of Common Stock outstanding immediately after such event, and (2) the
number of shares of Common Stock for which this Warrant may be exercised
immediately before such event shall be adjusted by multiplying such number by a
fraction, the numerator of which is the Exercise Price immediately before such
event and the denominator of which is the Exercise Price immediately after such
event, such that the aggregate Exercise Price for all shares of

                                       2

<PAGE>

Common stock issuable pursuant to this Warrant immediately after such event
shall equal the aggregate Exercise Price for all shares of Common Stock issuable
pursuant to this Warrant immediately before such event.

6.       RESERVATION AND LISTING OF SHARES.

         The Company shall at all times reserve and keep available out of its
authorized Common Stock shares of Common Stock solely for the purpose of
issuance upon the exercise of this Warrant. The Company covenants and agrees
that, upon exercise of this Warrant and payment of the Exercise Price therefor,
all shares of Common stock issuable upon such exercise shall be duly and validly
issued, fully paid and non-assessable. If applicable, as long as this Warrant
shall be outstanding, the Company shall use its best efforts to cause all shares
of Common Stock issuable upon the exercise of this Warrant to be listed (subject
to official notice of issuance) on all securities exchanges on which the Common
Stock is then listed. This Warrant and the Warrant Shares are subject to
dilution by the issuance of additional securities by the Company.

7.       NOTICES TO WARRANT HOLDER.

         Nothing contained in this Warrant shall be construed as conferring upon
the holder hereof the right to vote the Warrant Shares prior to their issuance
or any other rights as a stockholder of the Company.

8.       NOTICES.

         All notices, requests, consents and other communications hereunder
