                        Bridge Facility Commitment Letter

Ladies and Gentlemen:

          You have advised UBS Loan Finance LLC ("UBS"), UBS Securities LLC
("UBSS") and General Electric Capital Corporation ("GE Capital" and, together
with UBS and UBSS, "we" or "us") that Inverness Medical Innovations, Inc., a
Delaware corporation ("Borrower" or "you") proposes to form a wholly owned
subsidiary ("Merger Sub"), which will acquire (the "Acquisition") all of the
outstanding capital stock (the "Shares") of Biosite Incorporated (the "Acquired
Business"). The Acquisition will be effected by Borrower and Merger Sub entering
into a merger agreement (the "Acquisition Agreement") with the Acquired Business
pursuant to which Merger Sub will commence a tender offer (the "Tender Offer")
for the Shares. The Tender Offer shall be conditioned upon not less than a
majority (calculated on a fully diluted basis) of such Shares and not less than
a majority of the voting power of the outstanding shares of capital stock of the
Acquired Business entitled to vote in the election of directors being validly
tendered and not withdrawn. Merger Sub will, if the Tender Offer, together with
any exercise of the "top-up option," does not result in Merger Sub acquiring 90%
or more of the Shares (or such other amount as is sufficient for Merger Sub to
effect a "short form" merger under the Delaware General Corporation Law (such
amount, the "Minimum Condition")), acquire 100% of the outstanding capital stock
of the Acquired Business and merge with and into the Acquired Business (the
"Two-Step Merger" and the date of the consummation of the Two-Step Merger, if
applicable, the "Second Closing Date") pursuant to the Acquisition Agreement. If
the Minimum Condition is satisfied, immediately following completion of the
Tender Offer, the Acquired Business will be merged with and into Merger Sub (the
"One-Step Merger"; the One-Step Merger or the Two-Step Merger, as applicable,
the "Merger") pursuant to a short-form merger under Section 253 of the Delaware
General Corporation Law. All references to "dollars" or "$" in this agreement
and the attachments hereto (collectively, this "Commitment Letter") are
references to United States dollars. All references to "Borrower" or "Borrower
and its subsidiaries" for any period from and after consummation of the Tender
Offer shall include the Acquired Business.



                                       -2-


          We understand that the sources of funds required to fund the
Acquisition consideration, to repay existing indebtedness of Borrower and the
Acquired Business and their respective subsidiaries of up to $162.0 million (the
"Refinancing"), to pay fees, commissions and expenses in connection with the
Transactions (as defined below) and to provide ongoing working capital
requirements of Borrower and its subsidiaries following the Transactions will
include:

     -    senior secured credit facilities consisting of (i) a senior secured
          term loan facility to Borrower of $1,150.0 million ($850.0 million if
          the joint venture (the "Joint Venture") anticipated to be entered into
          among the Borrower and The Procter & Gamble Company for the
          development, manufacturing, marketing and sale of existing and
          to-be-developed consumer diagnostic products outside of the fields of
          cardiology and diabetes is consummated on or prior to the Closing
          Date) (the "Term Loan Facility") and (ii) a senior secured revolving
          credit facility to Borrower of up to $150.0 million (the "Revolving
          Credit Facility" and, together with the Term Loan Facility, the "Bank
          Facilities"); and

     -    the issuance by Borrower of up to $317.5 million aggregate gross
          proceeds of unsecured senior subordinated notes (the "Notes") pursuant
          to a public offering or Rule 144A or other private placement (the
          "Notes Offering") or, in the event the Notes are not issued at the
          time the Transactions are consummated, borrowings by Borrower of up to
          $317.5 million under a senior subordinated unsecured credit facility
          (the "Bridge Facility" and, together with the Bank Facilities, the
          "Facilities"), as described in the Bridge Facility Summary of
          Principal Terms and Conditions attached hereto as Annex I (the "Term
          Sheet").

No other financing will be required for the uses described above. Immediately
following the Transactions, neither Borrower nor any of its subsidiaries will
have any indebtedness or preferred equity other than the Bank Facilities, the
Notes or the Bridge Facility, $132.5 million of your 3% senior subordinated
convertible notes due 2016 and other limited indebtedness to be agreed
(including indebtedness contemplated by paragraph 7 of the Conditions Annex (as
defined below)). As used herein, the term "Transactions" means the Acquisition,
the Tender, the Merger, the Refinancing, the initial borrowings under the Bank
Facilities, the issuance of the Notes or the borrowings under the Bridge
Facility and the payments of fees, commissions and expenses in connection with
each of the foregoing.

     Commitments.

          You have requested that UBS commit to provide 60% of the Bridge
Facility, that GE Capital commit to provide 40% of the Bridge Facility and that
UBSS agree to structure, arrange and syndicate the Bridge Facility.

          UBS is pleased to advise you of its commitment to provide 60% of the
Bridge Facility to Borrower upon the terms and subject to the conditions set
forth or referred to in this Commitment Letter. GE Capital is pleased to advise
you of its commitment to provide 40% of the Bridge Facility to Borrower upon the
terms and subject to the conditions set forth or referred to in this Commitment
Letter. The commitment of UBS, GE Capital and each other Lender (as defined
below) hereunder is subject to the negotiation, execution and delivery of
definitive documentation (the "Bridge Documentation)



                                       -3-


with respect to the Bridge Facility reasonably satisfactory to UBS, GE Capital
and the other Lenders reflecting the terms and conditions set forth in the Term
Sheet, in Annex II hereto (the "Conditions Annex") and in the letter of even
date herewith addressed to you providing, among other things, for certain fees
relating to the Bridge Facility (the "Fee Letter"). You agree that the closing
date of the Transactions and the concurrent closing of the Facilities, and if
applicable, the Notes Offering (the "Closing Date") shall be a date consistent
with the Tender Offer closing date, but in any event shall not occur until the
conditions hereof and in the Term Sheet and the Conditions Annex (including the
conditions to initial funding) have been satisfied.

     Syndication.

          It is agreed that UBSS will act as the sole and exclusive advisor,
arranger and bookmanager for the Bridge Facility, and, in consultation with you,
will exclusively manage the syndication of the Bridge Facility, and will, in
such capacities, exclusively perform the duties and exercise the authority
customarily associated with such roles. It is further agreed that no additional
advisors, agents, co-agents, arrangers or bookmanagers will be appointed and no
Lender (as defined below) will receive compensation with respect to any of the
Bridge Facility outside the terms contained herein and in the Fee Letter in
order to obtain its commitment to participate in the Bridge Facility, in each
case unless you and we so agree.

          UBS and GE Capital reserve the right, prior to or after the execution
of the Bridge Documentation, to syndicate all or a portion of their respective
commitments to one or more institutions that will become parties to the Bridge
Documentation (UBS, GE Capital and the institutions becoming parties to the
Bridge Documentation, the "Lenders"). Upon any such additional Lender issuing
its commitment to provide a portion of the Bridge Facility, UBS and GE Capital
shall be released from a portion of their respective commitments in respect of
the Bridge Facility in an aggregate amount equal to the commitment of such
Lender with the reasonable consent of the Borrower (not to be unreasonably
withheld).

          UBSS will exclusively manage all aspects of the syndication of the
Bridge Facility, including selection of additional Lenders, determination of
when UBSS will approach potential additional Lenders, awarding of any naming
rights and the final allocations of the commitments in respect of the Bridge
Facility among the additional Lenders. You agree to, and to use commercially
reasonable efforts to cause the Acquired Business to (including with a covenant
to such effect in the Acquisition Agreement), reasonably assist UBSS in
achieving a timely syndication of the Bridge Facility that is reasonably
satisfactory to UBSS and the Lenders participating in the Bridge Facility. To
assist UBSS in its syndication efforts, you agree that you will, and will cause
your representatives and advisors to, and will use commercially reasonable
efforts to cause the Acquired Business and its representatives and advisors to,
(a) promptly prepare and provide all financial and other information as UBSS may
reasonably request with respect to Borrower, the Acquired Business, their
respective subsidiaries and the transactions contemplated hereby, including but
not limited to financial projections (the "Projections") relating to the
foregoing, (b) provide copies of any due diligence reports or memoranda prepared
at the direction of you or any of your affiliates by legal, accounting, tax or
other advisors in connection with the Acquisition (subject to the delivery of
customary non-disclosure agreements reasonably acceptable to UBSS), (c) use
commercially reasonable efforts to ensure that such syndication efforts benefit
materially from existing lending relationships of Borrower, the Acquired
Business and




                                      -4-


their respective subsidiaries, (d) make available to prospective Lenders senior
management and advisors of Borrower and its subsidiaries (and use commercially
reasonable efforts to make available to prospective Lenders senior management
and advisors of the Acquired Business and its subsidiaries), (e) host, with
UBSS, one or more meetings with prospective Lenders under the Bridge Facility,
(f) assist UBSS in the preparation of one or more confidential information
memoranda satisfactory to UBSS and other marketing materials to be used in
connection with the syndication of the Bridge Facility and (g) obtain, at your
expense, monitored public ratings of the Bridge Facility and the Notes from
Moody's Investors Service ("Moody's") and Standard & Poor's Ratings Group
("S&P") at least 30 days prior to the Closing Date and to participate in the
process of securing such ratings, including having senior management of
Borrower, and using commercially reasonable efforts to have senior management of
the Acquired Business, meet with such rating agencies.

          In connection with such syndication, UBS agrees, or shall cause its
affiliates, to manage such syndication process such that during such syndication
with respect to every dollar syndicated in respect of the Bridge Facility, such
dollar shall reduce each of UBS' and GE Capital's Bridge Facility commitments
and/or loans on a pro rata basis (determined based on the amount of each such
commitment and/or loan of UBS and GE Capital).

          At UBSS's request, you agree to prepare a version of the information
package and presentation and other marketing materials to be used in connection
with the syndication that do not contain material non-public information
concerning Borrower or the Acquired Business, their respective affiliates or
their securities. In addition, you agree that unless specifically labeled
"Private -- Contains Non-Public Information," no information, documentation or
other data disseminated to prospective Lenders in connection with the
syndication of the Bridge Facility, whether through an Internet website
(including, without limitation, an IntraLinks workspace), electronically, in
presentations at meetings or otherwise, will contain any material non-public
information concerning Borrower or the Acquired Business, their respective
affiliates or their securities.

     Information.

          You hereby represent that (a) all information (other than the
Projections) that has been or will be made available to us or any of the Lenders
by you, the Acquired Business or any of your or their respective representatives
in connection with the transactions contemplated hereby (the "Information"),
when taken as a whole, is and will be correct in all material respects and does
not and will not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements contained therein, in the
light of the circumstances under which such statements are made, not misleading
and (b) the Projections that have been or will be made available to us or any of
the Lenders by you, the Acquired Business or any of your or their respective
representatives in connection with the transactions contemplated hereby have
been and will be prepared in good faith based upon assumptions believed by you
to be reasonable (it being understood that projections by their nature are
inherently uncertain and no assurances are being given that the results
reflected in the Projections will be achieved). You agree to supplement the
Information and the Projections from time to time and agree to promptly advise
us and the Lenders of all developments materially affecting Borrower, the
Acquired Business, any of their respective subsidiaries or affiliates or the
transactions contemplated hereby or the accuracy of Information and Projections
previously furnished to us or any of the Lenders.



                                      -5-


     Compensation.

          As consideration for the commitments of the Lenders hereunder with
respect to the Bridge Facility and the agreement of UBSS to structure, arrange
and syndicate the Bridge Facility and to provide advisory services in connection
therewith, you agree to pay, or cause to be paid, the fees set forth in the Term
Sheet and the Fee Letter. Once paid, such fees shall not be refundable under any
circumstances.

     Conditions.

          The respective commitments of UBS and GE Capital hereunder with
respect to the Bridge Facility and UBSS's agreement to perform the services
described herein may be terminated by UBS or GE Capital, as applicable, if (i)
any condition set forth in the Term Sheet or the Conditions Annex is not
satisfied or you have not complied with this Commitment Letter or the Fee Letter
in any material respect or (ii) there occurs a "Company Material Adverse Effect"
(as defined in the Acquisition Agreement). Notwithstanding anything in this
Commitment Letter, the Fee Letter, the Bridge Documentation or any exhibit,
annex or condition hereto or thereto or any other letter agreement or other
undertaking concerning the financing of the Transactions to the contrary, (x)
the only representations relating to the Borrower, the Acquired Business, their
respective subsidiaries and their businesses the making of which shall be a
condition to availability of the Bridge Facility on the Closing Date or, if
applicable, the Second Closing Date shall be (A) such of the representations
made by the Acquired Business in the Acquisition Agreement, as are material to
the interests of the Lenders, but only to the extent that you have the right to
terminate your obligations under the Acquisition Agreement as a result of a
breach of such representations in the Acquisition Agreement and (B) the
Specified Representations (as defined below) and (y) the terms of the Bridge
Documentation shall be in a form such that they do not impair availability of
the Bridge Facility on the Closing Date if the conditions set forth herein and
in the Term Sheet are satisfied. Those matters that are not covered by or made
clear under the provisions of this Commitment Letter are subject to the approval
and agreement of you and us; provided that such approvals and agreements shall
be in a manner that is consistent with the Term Sheet. For purposes hereof,
"Specified Representations" means the representations and warranties set forth
in the Term Sheet relating to corporate power and authority, due authorization,
execution and delivery of the Bridge Documentation, no conflicts with material
contractual restrictions, the enforceability of the Bridge Documentation,
Federal Reserve margin regulations and the Investment Company Act.

     Clear Market.

          From the date of this Commitment Letter until our completion of
syndication (as determined by us and notified in writing to you) of the Bridge
Facility and, if later, of the distribution of the Notes, you will ensure that
no financing for Borrower, the Acquired Business or any of their respective
subsidiaries or affiliates (other than the Bank Facilities, Bridge Facility or
the Notes) is announced, syndicated or placed without the prior written consent
of UBS if such financing, syndication or placement would have, in the reasonable
judgment of UBS, a detrimental effect in any material respect upon the
transactions contemplated hereby.



                                      -6-


     Indemnity and Expenses.

          By your acceptance below, you hereby agree to indemnify and hold
harmless us and the other Lenders and our and their respective affiliates
(including, without limitation, controlling persons) and the directors,
officers, employees, advisors and agents of the foregoing (each, an "Indemnified
Person") from and against any and all losses, claims, costs, expenses, damages
or liabilities (or actions or other proceedings commenced or threatened in
respect thereof) that arise out of or in connection with this Commitment Letter,
the Term Sheet, the Conditions Annex, the Fee Letter, the Bridge Facility or any
of the transactions contemplated hereby or thereby or the providing or
syndication of the Bridge Facility (or the actual or proposed use of the
proceeds thereof), and to reimburse each Indemnified Person promptly upon its
written demand for any legal or other expenses incurred in connection with
investigating, preparing to defend or defending against, or participating in,
any such loss, claim, cost, expense, damage, liability or action or other
proceeding (whether or not such Indemnified Person is a party to any action or
proceeding); provided that any such obligation to indemnify, hold harmless and
reimburse an Indemnified Person shall not be applicable to the extent determined
by a final, non-appealable judgment of a court of competent jurisdiction to have
resulted solely from the gross negligence or willful misconduct of such
Indemnified Person. You shall not be liable for any settlement of any such
proceeding effected without your written consent, but if settled with such
consent or if there shall be a final judgment against an Indemnified Person, you
shall, subject to the proviso in the preceding sentence, indemnify such
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. You shall not, without the prior written consent of any
Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which such Indemnified Person is or could have been a
party and indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement (i) includes an unconditional release of such Indemnified
Person from all liability or claims that are the subject matter of such
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability, or a failure to act by or on behalf of such Indemnified Person.
None of us or any other Lender (or any of their respective affiliates) shall be
responsible or liable to Borrower, the Acquired Business or any of their
respective subsidiaries, affiliates or stockholders or any other person or
entity for any indirect, punitive or consequential damages which may be alleged
as a result of this Commitment Letter, the Term Sheet, the Conditions Annex, the
Fee Letter, the Bridge Facility or the transactions contemplated hereby or
thereby. In addition, you hereby agree to reimburse us and each of the Lenders
from time to time upon demand for all reasonable out-of-pocket costs and
expenses (including, without limitation, reasonable legal fees and expenses of
UBS, UBSS and GE Capital, appraisal, consulting and audit fees, and printing,
reproduction, document delivery, travel, communication and publicity costs)
incurred in connection with the syndication and execution of the Bridge
Facility, and the preparation, review, negotiation, execution and delivery of
this Commitment Letter, the Term Sheet, the Conditions Annex, the Fee Letter,
the Bridge Documentation and the administration, amendment, modification or
waiver thereof (or any proposed amendment, modification or waiver), whether or
not the Closing Date occurs or any Bridge Documentation is executed and
delivered or any extensions of credit are made under the Bridge Facility.

                                      ("Borrower").

Sole Arranger:                        UBS Securities LLC ("UBSS" or the
                                      "Arranger").

Lenders:                              A syndicate of banks, financial
                                      institutions and other entities, including
                                      UBS Loan Finance LLC ("UBS"), General
                                      Electric Capital Corporation ("GE

                                      "Administrative Agent").

Type and Amount of Bridge Facility:   $317.5 million senior subordinated
                                      unsecured bridge loan facility (the
                                      "Bridge Facility").

Purpose:                              Proceeds of borrowings under the Bridge
                                      Facility (the "Initial Loans") will be
                                      used to finance a portion of the
                                      Acquisition consideration and the

                                      Initial Loan has not been previously
                                      repaid in full on or prior to the Maturity
                                      Date, subject to the conditions outlined
                                      below under "Conditions to Conversion of
                                      the Initial Loans," such Initial Loan

                                      a "Extended Term Loan" and, together with
                                      the Initial Loans, the "Loans") maturing
                                      on the eighth anniversary of the Closing
                                      Date (the "Final Maturity Date"). The

                                      and the Extended Term Loans will have the
                                      option (i) in the case of Initial Loans,
                                      at the Maturity Date or (ii) in the case
                                      of Extended Term Loans, at any time or

                                      having the terms set forth in the term
                                      sheet attached hereto as Exhibit A.

Availability:                         Upon satisfaction of conditions precedent
                                      to drawing set forth herein, in the
                                      Conditions Annex and in the body of the
                                      Commitment Letter, Initial Loans may be
                                      drawn, on the Closing Date, but only after
                                      the Term Loan Facility has been fully
                                      drawn, up to the amount of the commitments
                                      under the Bridge Facility, and additional
                                      Initial Loans may be drawn on the Second
                                      Closing Date in an amount up to the
                                      remaining commitments under the Bridge
                                      Facility. Any unused commitments shall
                                      expire upon the earlier of the
                                      consummation of the Acquisition and one
                                      year after the date of this Commitment
                                      Letter.

Interest and Fees:                    Prior to the Maturity Date, the Initial
                                      Loans will accrue interest at a rate per
                                      annum equal to (as determined on the
                                      Closing Date and each three-month period
                                      thereafter) the three-month London
                                      Interbank Offered Rate ("LIBOR") as
                                      determined by UBS for a corresponding U.S.
                                      dollar deposit amount (adjusted quarterly)
                                      plus the Spread. The Spread will initially
                                      be, 475 basis points. If the Initial Loans
                                      are not repaid in full within six months
                                      following the Closing Date, the Spread
                                      will increase by 50 basis points at the
                                      beginning of the subsequent three-month
                                      period and shall increase by an additional
                                      50 basis points at the beginning of each
                                      three-month period thereafter (but, in any
                                      event, not on the Maturity Date). LIBOR
                                      will be adjusted for maximum statutory
                                      reserve requirements (if any). The initial
                                      Spread shall increase by 50 basis points
                                      if the Bridge Facility is not rated at
                                      least Caa1 by Moody's and at least CCC+ by
                                      S&P (in each case with a stable outlook or
                                      better and pro forma for the
                                      Transactions).

                                      Interest on the Initial Loans will be
                                      payable in arrears at the end of each
                                      three-month period and at the Maturity
                                      Date. Interest on the Initial Loans shall
                                      not exceed 11.50% per annum (the "Total
                                      Cap"); provided that the Total Cap for the
                                      Initial Loans and the Exchange Notes shall
                                      each be increased by 50 basis points if
                                      the Bridge Facility is not rated at least
                                      Caa1 (stable or positive outlook) by
                                      Moody's and CCC+ (stable or positive
                                      outlook) by S&P.

                                      Following the Maturity Date, all
                                      outstanding Extended Term Loans will
                                      accrue interest at the rate provided for
                                      in the Exchange Notes in Exhibit A hereto;
                                      provided that a holder of an Extended Term
                                      Loan may at any time fix the rate thereon
                                      at the effective rate (such loans, "Fixed
                                      Rate Term Loans").




                                      -3-



                                   
                                      Calculation of interest shall be on the
                                      basis of actual days elapsed in a year of
                                      360 days.

                                      A per annum commitment fee on the undrawn
                                      portion of the commitments in respect of
                                      the Bridge Facility shall accrue from the
                                      Closing Date at a rate per annum equal to
                                      one half of the Spread at any time, and
                                      shall be payable quarterly in arrears.

Default Interest:                     Upon the occurrence and during the
                                      continuance of an event of default,
                                      interest will accrue on the amount of any
                                      loan or other amount outstanding under the
                                      Bridge Facility at a rate of 2.0% per
                                      annum plus the rate otherwise applicable
                                      to the loans under the Bridge Facility and
                                      will be payable on demand.

Mandatory Prepayment:                 Borrower will be required to prepay
                                      Initial Loans and Extended Term Loans
                                      (other than Fixed Rate Term Loans), and
                                      offer to prepay Fixed Rate Term Loans, on
                                      a pro rata basis, at par plus accrued and
                                      unpaid interest, in an amount equal to (a)
                                      100% of the net proceeds received from the
                                      sale or other disposition of assets of
                                      Borrower or any of its subsidiaries after
                                      the Closing Date, other than sales of
                                      inventory in the ordinary course of

                                      minimum amounts to be agreed, a portion of
                                      its loans and commitments under the Bridge
                                      Facility. Assignments will require payment
                                      of an administrative fee to the
                                      Administrative Agent and, except for an
                                      assignment to an existing Lender or an

                                      consent of the Administrative Agent, which
                                      consent shall not be unreasonably
                                      withheld. In addition, each Lender may
                                      sell participations




                                      -7-



                                   
                                      in all or a portion of its loans and
                                      commitments under the Bridge Facility;
                                      provided that no purchaser of a
                                      participation shall have the right to
                                      exercise or to cause the selling Lender to
                                      exercise voting rights in respect of the
                                      Bridge Facility (except as to certain

                                      expenses) of the Lenders and the

                                      (including but not limited to reasonable

                                      liabilities to the extent determined by a
                                      final, non-appealable judgment of a court
                                      of competent jurisdiction to have been
                                      incurred solely by reason of the gross
                                      negligence or willful misconduct of such
                                      person.

                                      yield protection provisions, customary for
                                      facilities of this nature, protecting the
                                      Lenders in the event of unavailability of
                                      LIBOR, breakage losses and reserve and

                                      All payments are to be free and clear of
                                      any present or future taxes, withholdings
                                      or other deductions whatsoever (other than
                                      income taxes in the jurisdiction of the
                                      Lender's applicable lending office).

                                      the Administrative Agent for such taxes
                                      paid

                                      by the Lenders or the Administrative
                                      Agent. The Lenders will use commercially
                                      reasonable efforts to minimize to the
                                      extent possible any applicable taxes and
                                      Borrower will indemnify the Lenders and
                                      the Administrative Agent for such taxes

                                      modifications or amendments requiring the
                                      consent of Lenders holding a greater
                                      percentage (or all) of the total Loans and
                                      commitments under the Bridge Facility.

                                                                         ANNEX I

                    Summary of Principal Terms and Conditions
                                of Exchange Notes

          Capitalized terms used but not defined herein have the meanings given
(or incorporated by reference) in the Summary of Principal Terms and Conditions
of the Bridge Facility to which this Exhibit A is attached.


                                   
Issuer:                               Borrower will issue Exchange Notes under
                                      an indenture which complies with the Trust
                                      Indenture Act (the "Indenture"). Borrower
                                      in its capacity as issuer of the Exchange
                                      Notes is referred to as the "Issuer."

Guarantors:                           Same as Initial Loans.

Principal Amount:                     The Exchange Notes will be available only
                                      in exchange for the Initial Loans (at the
                                      Maturity Date) or the Extended Term Loans
                                      (at any time). The principal amount of any
                                      Exchange Note will equal 100% of the
                                      aggregate principal amount of the Initial
                                      Loans or the Extended Term Loans for which
                                      it is exchanged.

Maturity:                             The Exchange Notes will mature on the
                                      eighth anniversary of the Closing Date.

Interest Rate:                        The Exchange Notes will bear interest at a
                                      rate equal to the Initial Rate (as defined
                                      below) plus the Exchange Spread (as
                                      defined below). Any holder of an Exchange
                                      Note may at any time fix the rate thereon
                                      at the effective rate (such Exchange
                                      Notes, "Fixed Rate Exchange Notes").
                                      Notwithstanding the foregoing, the
                                      interest rate in effect at any time shall
                                      not exceed the Total Cap; provided that
                                      upon transfer of any Exchange Note to a
                                      person that is not a holder of Exchange
                                      Notes on the Maturity Date, the interest
                                      rate thereon shall thereupon be the Total
                                      Cap. The "Initial Rate" shall be equal to
                                      the interest rate applicable to the
                                      Initial Loans and in effect on the
                                      Maturity Date. "Exchange Spread" shall
                                      mean 50 basis points during the
                                      three-month period commencing on the
                                      Maturity Date and shall increase by 50
                                      basis points at the beginning of each
                                      subsequent three-month period.

                                      Calculation of interest shall be on the
                                      basis of the actual number of days elapsed
                                      in a year of twelve 30-day months.

Default Interest:                     In the event of a payment default on the
                                      Exchange Notes, interest on the Exchange
                                      Notes will accrue at a rate of 2.0% per
                                      annum in excess of the rate otherwise
                                      applicable to the




                                       -2-



                                   
                                      Exchange Notes, and will be payable in
                                      accordance with the provisions described
                                      above under the heading "Interest Rate."

Ranking:                              Same as Initial Loans.

Mandatory Offer to Purchase:          The Issuer will be required to offer to
                                      purchase the Exchange Notes upon a Change
                                      of Control (to be defined in the
                                      Indenture) at 101% of the principal amount
                                      thereof plus accrued interest to the date
                                      of purchase.

Optional Redemption:                  Exchange Notes (other than Fixed Rate
                                      Exchange Notes) will be redeemable at the
                                      option of the Issuer, in whole or in part,
                                      at any time at par plus accrued and unpaid
                                      interest to the redemption date.

                                      Except as set forth in the following
                                      paragraph, Fixed Rate Exchanges Notes will
                                      not be redeemable at the option of the
                                      Issuer prior to the third anniversary of

                                      amount of Exchange Notes originally issued
                                      shall remain outstanding.

                                      Exchange Notes.

                                      In addition, unless and until the Issuer
                                      has consummated the exchange offer and, if
                                      required, caused the shelf registration
                                      statement to become effective, the holders
                                      of the Exchange Notes will have the right
                                      to "piggy-back" the Exchange Notes in the

                                      (subject to customary scale-back
                                      provisions) that are registered by the
                                      Issuer (other than on a Form S-4) unless
                                      all the Exchange Notes and Extended Term
                                      Loans will be redeemed or repaid from the
                                      proceeds of such securities.

                                      have the absolute and unconditional right
                                      to transfer the Exchange Notes in
                                      compliance with applicable law to any
                                      third parties.

Covenants:                            Those typical for an indenture governing a
                                      high yield note issue of a new issuer.

Events of Default:                    Those typical for an indenture governing a
