AGREEMENT AND AMENDMENT TO LOAN DOCUMENTS

        FOURTH AMENDMENT, dated as of February 5, 2004 (this "Amendment"), to
the Second Amended and Restated Credit Agreement, dated as of September 30, 2003
(as amended, supplemented or otherwise modified from time to time, the "Credit
Agreement"), by and among General Electric Capital Corporation, as Agent and
Lender ("Agent"), Inverness Medical Innovations, Inc. ("Innovations"), Wampole
Laboratories, LLC, and Inverness Medical (UK) Holdings Limited, as borrowers
("Borrowers"), the other Credit Parties signatory thereto, Merrill Lynch
Capital, a division of Merrill Lynch Business Financial Services Inc., as
documentation agent and co-syndication agent, UBS Securities LLC, as
co-syndication agent, and the lenders signatory thereto from time to time
(collectively, the "Lenders") and Amendment to the US Guaranty, US Intellectual
Property Security Agreement, US Pledge Agreement and US Security Agreement (as
such terms are defined in the Credit Agreement).

W I T N E S S E T H

        WHEREAS, it is and was the intent of the Agent, Lenders, Borrowers and
other Credit Parties to structure the facilities under the Credit Agreement such
that no European Credit Party (as defined in the Credit Agreement prior to
giving effect to this Amendment) would guarantee or otherwise provide security
for any Obligations owing by any US Credit Party (as defined in the Credit
Agreement prior to giving effect to this Amendment);

        WHEREAS, the Borrowers have notified Agent that, for purposes of
Section 956 of the IRC, as a result of the limited liability nature of Morpheus
Acquisition LLC ("Morpheus LLC") the guaranty by Morpheus LLC of the Obligations
owing by US Credit Parties (the "US Obligations") and other provisions of credit
support for the US Obligations given by Morpheus LLC, Inverness Medical
Switzerland GmbH will be deemed to have guaranteed and provided security for the
US Obligations;

        WHEREAS, the parties desire to amend the Credit Agreement and the Loan
Documents to reflect the original intent of all parties and accordingly agree
that all such amendments be effective as of the date of execution thereof;

        WHEREAS, Borrowers have requested that the definition of Interest
Expense be amended to exclude certain non-cash charges; and

        WHEREAS, the Borrowers, Agent and Lenders have agreed to amend the
Credit Agreement and the Loan Documents on the terms and conditions set forth
herein.

        NOW THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt, adequacy and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

        1.    Definitions.    Capitalized terms not otherwise defined herein
shall have the meanings ascribed to them in the Credit Agreement.

        2.    Amendment to Section 5.11 of the Credit Agreement.    As of the
Amendment Effective Date (as hereinafter defined), Section 5.11 of the Credit
Agreement shall be amended by inserting the following sentence at the beginning
thereof:

        "If at any time any European Credit Party that is treated for purposes
of Section 956 of the IRC as a "controlled foreign corporation, thereafter fails
to be treated as a controlled foreign corporation, then at the request of the
Agent or the Requisite Lenders, Innovations shall cause each such European
Credit Party to execute and deliver to the Agent (a) a Guaranty in form and
substance reasonably satisfactory to the Agent, guarantying the Obligations of
US Borrower hereunder and under the other Loan Documents, and (b) Collateral
Documents in form and substance reasonably satisfactory to Agent, granting to
Agent a Lien over such European Credit Party's properties and assets, in each
case,

--------------------------------------------------------------------------------

to the extent such European Credit Party has, or is required to have, entered
into a Guaranty or a Collateral Document with respect to the Obligations of the
European Credit Parties, and to the extent such Guaranty or Collateral Document
is not prohibited by the law of the jurisdiction of formation of such European
Credit Party, and shall cause the pledge of all Stock of such European Credit
Party to Agent to secure all of the Obligations to the extent only a portion of
such Stock was previously pledged to Agent to secure the Obligations of US
Credit Parties."

        3.    Amendment to Annex A to the Credit Agreement.    As of the
Amendment Effective Date (as hereinafter defined), Annex A to the Credit
Agreement shall be amended by deleting the definitions "European Credit Party",
"Interest Expense", "Obligations", "Senior US Leverage Ratio" and "US Credit
Party", and inserting in lieu thereof the following terms respectively:

        "European Credit Party" means each of European Borrower, Swissco and
Orgenics Holdings, Morpheus LLC and each of their respective Subsidiaries (other
than the Excluded European Subsidiaries).

        "Interest Expense" means, with respect to any Person for any fiscal
period, interest expense (whether cash or non-cash) of such Person determined in
accordance with GAAP for the relevant period ended on such date, including,
interest expense with respect to any Funded Debt of such Person and interest
expense for the relevant period that has been capitalized on the balance sheet
of such Person but excluding all non-cash charges as they relate to the
amortization or write-offs of capitalized financing or debt origination fees or
costs.

        "Obligations" means all loans, advances, debts, liabilities and
obligations for the performance of covenants, tasks or duties or for payment of
monetary amounts (whether or not such performance is then required or
contingent, or such amounts are liquidated or determinable) owing by any Credit
Party to Agent or any Lender, and all covenants and duties regarding such
amounts, of any kind or nature, present or future, whether or not evidenced by
any note, agreement or other instrument, arising under the Agreement or any of
the other Loan Documents. This term includes all principal, interest (including
all interest that accrues after the commencement of any case or proceeding by or
against any Credit Party in bankruptcy, whether or not allowed in such case or
proceeding), Fees, Charges, expenses, attorneys' fees and any other sum
chargeable to any Credit Party under the Agreement or any of the other Loan
Documents. Notwithstanding the forgoing, with respect to Morpheus LLC, in its
capacity as (i) a Grantor under the US Security Agreement and the US
Intellectual Property Security Agreement, (ii) a Guarantor under the US
Guaranty, and (iii) a Pledgor under the US Pledge Agreement, "Obligations" or
similar terms under such documents shall mean Obligations of the European Credit
Parties and shall not include Obligations of the US Credit Parties.

        "Senior US Leverage Ratio" means with respect to all US Credit Parties
that are Reporting Credit Parties and Morpheus LLC, the ratio of (a) the
outstanding principal amount of the US Term Loan and the US Revolving Loan on
any date of determination to (b) the sum of LTM EBITDA attributable to the US
Credit Parties and Morpheus LLC for the twelve months ending on that date of
determination; provided that, for purposes of calculating compliance with the
Senior US Leverage Ratio for such period, US Borrower may include revenues
generated by licenses of US Borrower's Intellectual Property which have been
assigned to Swissco in an amount not to exceed $800,000 in the aggregate for
such period.

        "US Credit Party" means Innovations, US Borrower and each of their
respective Domestic Subsidiaries (other than Morpheus LLC and the Excluded US
Subsidiaries).

        4.    Amendment to Annex F to the Credit Agreement.    Clause (g) to
Annex F to the Credit Agreement shall be amended by inserting the words "and
Morpheus LLC, collectively" after the words US Credit Parties that are Reporting
Credit Parties in the first sentence thereof.

        5.    Amendment to the US Guaranty, US Security Agreement, US
Intellectual Property Security Agreement and US Pledge Agreement.    For the
avoidance of doubt, each of the US Guaranty, US Security Agreement, US

amended as of the Amendment Effective Date, to reflect amendments to the terms
therein which have the meanings ascribed to them in the Credit Agreement and
which are hereby being amended under Section 3 above.

and the Lenders to enter into this Amendment, the Credit Parties hereby, jointly

thereof, or before any arbitrator or panel of arbitrators, which (a) challenges
any Credit Party's right or power to enter into or perform any of its
obligations under this Amendment, the Credit Agreement and the other Loan
Documents to which it is a party, or the validity or enforceability of this
Amendment, the Credit Agreement or any Loan Document or any action taken
thereunder, or (b) has a reasonable risk of being determined adversely to any
Credit Party and that, if so determined, could be reasonably be expected to have
