Re: Commitment Letter for $1.3 billion Senior Secured Credit Facility

Dear Gentlemen:

You have advised General Electric Capital Corporation (“GE Capital” or “Agent”) and UBS Loan Finance LLC (“UBS,” and together with GE Capital,” we,” “us” or “our”) that Inverness Medical Innovations, Inc. (“Innovations” or “you”) is seeking, on behalf of certain of its subsidiaries to be determined (such subsidiaries are collectively referred to herein as the “Borrowers” and individually as a “Borrower”), up to $1.3 billion of financing (the “Financing”) (i) partially to finance the proposed all cash acquisition (the “Acquisition”) by a subsidiary of Innovations (“Acquisition Co.”) of all of the issued and outstanding stock (the “Shares”) of BioSite Incorporated (the “Target”), (ii) to refinance existing indebtedness of Innovations and its subsidiaries and (iii) for general working capital purposes, capital expenditures, permitted acquisitions and other general corporate purposes as provided for in the definitive Financing documentation. It is further our understanding that the Acquisition shall be consummated by Acquisition Co. entering into a merger agreement (the “Acquisition Agreement”) with the Target pursuant to which Acquisition Co. would merge with and into the Target. References herein to the “Transaction” shall include the Acquisition, the financings described herein and all other transactions related to the Acquisition and such financings.

You have advised us that, upon consummation of the Acquisition, the Target will become a wholly owned direct or indirect subsidiary of Innovations, and substantially all the existing

indebtedness of the Target and its subsidiaries will be repaid. In addition, we anticipate that upon the closing of the Transaction that, in addition to the Financing, the capital structure of Innovations and its subsidiaries shall consist of: (i) approximately $14 million of equipment financing notes issued by Innovations, the Target and their respective subsidiaries and (ii) senior subordinated debt (the “Senior Subordinated Debt”) issued or incurred by Innovations, the proceeds of which shall be used to partially finance the Acquisition.

You have asked that the Financing include: a $150 million revolving facility (the “Revolver”) and a $1.150 billion Term Loan B facility (the “Term Loan B”). Based on our understanding of the Transaction as described above and the information which you have provided to us to date, (a) GE Capital is pleased to offer, directly or through an affiliate, its commitment to provide a portion of the Financing in the amount of $100 million of the Revolver and $1.005 billion of the Term Loan B as described herein and (b) UBS is pleased to offer, directly or through an affiliate, its commitment to provide a portion of the Financing in the amount of $50 million of the Revolver and $145 million of the Term Loan B as described herein, in each case, subject to the terms and conditions outlined in the attached Summary of Terms (the “Term Sheet”, and together with this cover letter, this “Commitment Letter”).

Syndication.

Each of GE Capital and UBS intends and reserves the right, prior to or after the execution of definitive documentation for the Financing (the “Financing Documentation”), to syndicate all or a portion of its commitments under this Commitment Letter or its loans and commitments under the Financing Documentation, as the case may be, to one or more financial institutions that will become parties to such Financing Documentation pursuant to a syndication to be managed by GE Capital Markets, Inc. (“GECM”) (GE Capital, UBS and such financial institutions so becoming parties to such Financing Documentation being collectively referred to as the “Lenders”). The syndication of all or a portion of each of GE Capital’s and UBS’ commitments and/or loans under the Financing is hereinafter referred to as the “Primary Syndication”.

GECM will commence the Primary Syndication at a time mutually agreed upon by GECM and Innovations. It is understood and agreed that GECM will, in consultation with Innovations, manage and control all aspects of the Primary Syndication, including selection of the potential other Lenders, determination of when GECM will approach potential other Lenders and the time of acceptance of the other Lenders’ commitments, any naming rights, titles or roles to be awarded to the other Lenders, and the final allocations of the commitments among the other Lenders. It is further understood and agreed that (i) no additional agents, co-agents, co-arrangers or co-bookrunners shall be appointed, or other titles, names or roles conferred to any other Lender or any other person or entity, by Innovations or the Borrowers in respect of the Financing, (ii) the amount and distribution of fees among the other Lenders will be at GECM’s discretion and (iii) no other Lender will be offered by, or receive from, Innovations or the Borrowers compensation of any kind for its participation in the Financing, except as expressly provided for in this Commitment Letter or the Fee Letter or with the prior written consent of GECM. GECM shall have also been afforded a reasonable period of time, following your written authorization for the release of the confidential information memorandum prepared as part of the Evaluation Materials (as defined below) and the obtaining of ratings for the Financing from Moody’s Investor Services, Inc. and Standard & Poor’s and immediately prior to the date of closing of the Financing to complete the Primary Syndication.

2

In connection with the Primary Syndication, GECM agrees, or shall cause its affiliates, to manage the syndication process such that during the Primary Syndication (i) with respect to every dollar syndicated in respect of the Term Loan B, each such dollar shall reduce each of GE Capital’s and UBS’ Term Loan B commitments and/or loans on a pro rata basis (determined based on the amount of each such commitment and/or loan of GE Capital and UBS) until such time as GE Capital’s Term Loan B commitment and/or loan is reduced to $50 million, and for each dollar syndicated thereafter, to reduce UBS’ Term Loan B commitment and/or loan until such time as UBS’ Term Loan B commitment and/or loan is reduced to $0, and (ii) with respect to every dollar syndicated of the Revolver commitments, each such dollar shall reduce each of GE Capital’s and UBS’s Revolver commitments on a pro rata basis (determined based on the amount of each such Revolver commitment of GE Capital and UBS).

Innovations agrees to actively assist and cooperate (and to use commercially reasonable efforts to cause, the Target, each of their respective affiliates and all other necessary persons to assist and cooperate) with GE Capital, GECM and UBS in connection with the Primary Syndication. Such assistance shall include, without limitation (a) promptly preparing and providing to GE Capital, GECM and UBS all information with respect to Innovations, the Borrowers, the Target and their respective subsidiaries, the Transaction and the other transactions contemplated hereby, including all financial information and projections (the “Projections”), as GE Capital, GECM and UBS may reasonable request in connection with the Primary Syndication, (b) participating in Lender and other relevant meetings (including meetings with rating agencies), (c) providing direct contact during the Primary Syndication between Innovations’ senior management, representatives and advisors and those of the Target with potential Lenders, (d) using your commercially reasonable efforts to ensure that GECM’s syndication efforts benefit from your and the Target’s existing banking relationships, and (e) assisting GECM in the preparation of confidential information memoranda, presentations and other information materials regarding the Financing to be used in connection with the Primary Syndication and confirming (and causing the Target to confirm), prior to such materials being made available to potential Lenders, that such materials are complete and accurate in all material respects. Innovations also agrees that at its expense, it will work with GE Capital to procure a rating for the Financing from Moody’s Investors Service, Inc. and Standard & Poor’s Rating Services.

Until the completion of the Primary Syndication (as determined by GECM), Innovations and the Borrowers shall not (and shall cause their affiliates and the Target and its affiliates not to), without the prior written consent of GECM, offer, issue, place, syndicate or arrange any debt securities or debt facilities (including any renewals, restatements, restructurings or refinancing of any existing debt securities or debt facilities), attempt or agree to do any of the foregoing, announce or authorize the announcement of any of the foregoing, or engage in discussion concerning any of the foregoing (other than the Senior Subordinated Debt).

Information.

You hereby represent and covenant (and it is a condition to GE Capital’s and UBS’ respective commitments hereunder) that: (a) all information other than the Projections (the “Information”) that has been or will be made available to GE Capital, UBS and GECM by you or any of your affiliates or representatives is or will be, when furnished, complete and correct in all material respects and does not or will not, when furnished, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light of the circumstances under which such statements are made and (b)

3

the Projections that have been or will be made available to us by you or any of your affiliates or representatives have been or will be prepared in good faith based upon reasonable assumptions. You agree that if at any time prior to the closing of the Financing any of the representations in the preceding sentence would be incorrect if the Information or Projections were being furnished, and such representations were being made, at such time, then you will promptly supplement the Information or the Projections, as the case may be, so that such representations will be correct under those circumstances. You understand that in arranging and syndicating the Financing we may use and rely on the Information and Projections without independent verification thereof.

Innovations hereby authorizes and agrees, on behalf of itself, the Target, and their respective affiliates, that the Information, the Projections and all other information provided by or on behalf of Innovations and the Borrowers to GE Capital, UBS and GECM regarding the Transaction, Innovations and the Borrowers, the Target and their respective affiliates in connection with the Financing (collectively, the “Evaluation Material”) may be disseminated by or on behalf of GE Capital, UBS and GECM, and made available, to potential other Lenders and other persons, who have agreed to be bound by customary confidentiality undertakings (including, “click-through” agreements), all in accordance with GECM’s standard loan syndication practices (whether transmitted electronically by means of a website, e-mail or otherwise, or made available orally or in writing, including at potential Lender or other meetings). Innovations hereby further authorizes GECM to download copies of Innovations’ and the Borrowers’ and the Target’s logos from their respective websites and post copies thereof on an Intralinks^® workspace and use the logos on any confidential information memoranda, presentations and other marketing and materials prepared in connection with the Primary Syndication.

At GECM’s request, Innovations agrees to assist (and shall use its commercially reasonable efforts to cause Target to assist) in the preparation of a version of the information memorandum, presentation and other information materials regarding the Financing consisting exclusively of information that is either publicly available or not material with respect to Innovations, the Target, their respective affiliates and any of their respective securities for purposes of United States federal and state securities laws. You also hereby agree that (i) you will identify (arid cause the Target to identify) and clearly and conspicuously mark that portion of the Evaluation Materials (other than Evaluation Materials which have previously been filed with the Securities and Exchange Commission) that do not contain any material non-public information with respect to Innovations and the Borrowers or the Target or their securities for purposes of United States federal and state securities laws as “PUBLIC,” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof and (ii) by marking Evaluation Materials as “PUBLIC” or by publicly filing any Evaluation Materials with the Securities and Exchange Commission, GE Capital, UBS, GECM and the other potential Lenders shall be entitled to treat such Evaluation Materials as not containing any material non-public information with respect to Innovations and the Borrowers or the Target or their securities for purposes of United States federal and state securities laws.

Fee Letter.

As consideration for our commitments hereunder and GECM’s agreement to structure, arrange and syndicate the Financing, you agree to pay GE Capital and UBS the fees as set forth in the Term Sheet and in the Fee Letter dated the date hereof and delivered herewith with respect to the Financing (the “Fee Letter”). Once paid, such fees shall not be refundable under any circumstances.

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 GE Capital, UBS and you; provided, that such approvals and agreements shall be in a manner that is consistent with the Term Sheet.

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 Merger Sub entering into a merger agreement (the “Acquisition Agreement”) with the Acquired Business pursuant to which Merger Sub would merge with and into the Acquired Business. 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 Acquisition shall include the Acquired Business.

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 (as defined in the Term Sheet) 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 $450.0 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 $450.0 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 and other limited indebtedness to be agreed. As used herein, the term “Transactions” means the Acquisition, 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”) with respect to the Bridge Facility reasonably satisfactory to UBS, GE Capital and the other Lenders reflecting, among other things, 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 mutually agreed upon between you and us, but in any event shall not occur until the terms and 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 book-manager 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.

-2-

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.

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), actively 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 their respective subsidiaries, (d) make available to prospective Lenders senior management and advisors of Borrower, the Acquired Business and their respective 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 actively in the process of securing such ratings, including having senior management of Borrower and 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).

-3-

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.

ANNEX I

BRIDGE FACILITY

SUMMARY OF PRINCIPAL TERMS AND CONDITIONS¹

Borrower:	Inverness Medical Innovations, Inc. (“Borrower”). Borrower will own all of the equity interests of the Acquired Business on the Closing Date.
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 Capital”), arranged by UBSS.
Administrative Agent:	UBS AG, Stamford Branch (the “Administrative Agent”).
Type and Amount of Bridge Facility:	$450.0 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 Refinancing and to pay fees, commissions and expenses in connection therewith.
Maturity/Exchange:	All the Initial Loans will mature on the date that is one year following the Closing Date (the “Maturity Date”). If any 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 shall be converted into a term loan (each, 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 Lenders in respect of the Initial Loans 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 from time to time, to receive notes (the “Exchange Notes”) in exchange for such Initial Loans or Extended Term Loans having the terms set forth in the term sheet attached hereto as Exhibit A.
Availability:	Upon satisfaction of conditions precedent to drawing to be specified in the Bridge Documentation, a single drawing may be made on the Closing Date of up to the full amount of the Bridge Facility.

¹ All capitalized terms used but not defined herein shall have the meanings provided in the Commitment Letter to which this summary is attached.

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

-2-

	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 business and other exceptions to be agreed and subject to reinvestment rights to be agreed and prepayment of the Bank Facilities, (b) 100% of the net proceeds received by Borrower or any of its subsidiaries from the issuance of debt or preferred stock after the Closing Date, other than exceptions to be agreed and (c) 100% of the net proceeds received from the issuance of common equity (including, but not limited to, upon the exercise of warrants and options) by, or equity contributions to, Borrower after the Closing Date, other than exceptions to be agreed upon and (d) 100% of all casualty and condemnation proceeds received by Borrower or any of its subsidiaries, subject to reinvestment rights to be agreed and prepayment of the Bank Facilities.
Optional Prepayments:	The Initial Loans and Extended Term Loans (other than Fixed Rate Term Loans) may be prepaid, in whole or in part, at the option of Borrower, at any time with prior notice, at par plus accrued and unpaid interest and breakage costs. The Fixed Rate Term Loans will be subject to prepayment restrictions and premiums consistent with Fixed Rate Exchange Notes.
Guarantees:	The Bridge Facility will be fully and unconditionally guaranteed on a joint and several basis by all of the existing and future direct and indirect subsidiaries of Borrower including the Acquired Business (collectively, the “Guarantors”), subject to exceptions for foreign subsidiaries to the extent such guarantees would be prohibited by applicable law or would result in materially adverse tax consequences.
Security:	None.
Ranking:	Subordinated to the Bank Facilities; pari passu with or senior to all other obligations of Borrower and the guarantors.
Conditions to Borrowing:	Conditions precedent to borrowing under the Bridge Facility will be those set forth in the Commitment Letter and Annex II to the Commitment Letter.

Assignments and Participations	Each Lender may assign all or, subject to 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 affiliate of an existing Lender, the consent of the Administrative Agent, which consent shall not be unreasonably withheld.

Exhibit A to

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:	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 the Maturity Date. Thereafter, each Fixed Rate Exchange Note will be redeemable at the option of the Issuer at a premium equal to 50% of the coupon of such Fixed Rate Exchange Note, declining ratably to par on the date which is two years prior to the final maturity of the Exchange Notes. Each Fixed Rate Exchange Note will be redeemable at the option of the Issuer prior to the third anniversary of the Maturity Date with the net cash proceeds of qualified equity offerings of Borrower at a premium equal to the coupon on such Fixed Rate Exchange Note; provided that after giving effect to such redemption at least 65% of the aggregate principal amount of Exchange Notes originally issued shall remain outstanding.
Registration Rights:	The Issuer will be required to: •   within 60 days after the Maturity Date, file a registration statement for an offer to exchange the Exchange Notes for publicly registered notes with identical terms; •   use its reasonable best efforts to cause the registration statement to become effective under the Securities Act within 150 days after the Maturity Date; •   complete the exchange offer within 180 days after the Maturity Date; and •   file a shelf registration statement for the resale of the Exchange Notes if it cannot complete an exchange offer within those time periods listed above and in certain other circumstances. If the Issuer does not comply with these obligations, it will be required to pay additional interest to the holders of the Exchange Notes.

-2-

	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 registration of any debt securities (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.
Right to Transfer Exchange Notes:	The holders of the Exchange Notes shall 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 high yield note issue of a new issuer.
Governing Law:	The laws of the State of New York.

-3-
