SECTION 1.04. Classes and Types of Loans. For purposes of this Agreement, Loans may be classified and referred to by Class (e.g., a “Revolving Credit Loan”, “Tranche A Term Loan”, “Tranche B Term Loan” or “Incremental Term Loan”) or by Type (e.g., an “ABR Loan”, or a “Eurodollar Loan”) or by Class and Type (e.g., a “Eurodollar Revolving Credit Loan” or an “ABR Revolving Credit Loan”); each Series of Incremental Term Loans shall be deemed a separate Class of Loans hereunder. In similar fashion, (i) Borrowings may be classified and referred to by Class, by Type and by Class and Type, and (ii) Commitments may be classified and referred to by Class; each Series of Incremental Term Loan Borrowings and Incremental Term Loan Commitments shall be deemed a separate Borrowing and Commitment hereunder.

(a) Revolving Credit Loans. Subject to the terms and conditions set forth herein, each Revolving Credit Lender agrees to make Revolving Credit Loans to the Borrower from time to time during the Revolving Credit Availability Period in an aggregate principal amount that will not result in (i) such Lender’s Revolving Credit Exposure exceeding such Lender’s Revolving Credit Commitment or (ii) the total Revolving Credit Exposures exceeding the total Revolving Credit Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Revolving Credit Loans.

(b) Tranche A Term Loans. Subject to the terms and conditions set forth herein, each Tranche A Term Loan Lender agrees to make a Tranche A Term Loan to the Borrower on the Effective Date in a principal amount equal to its Tranche A Term Loan Commitment. Amounts prepaid or repaid in respect of Tranche A Term Loans may not be reborrowed.

(c) Tranche B Term Loans. Subject to the terms and conditions set forth herein, each Tranche B Term Loan Lender agrees to make a Tranche B Term Loan to the Borrower on the Effective Date in a principal amount equal to its Tranche B Term Loan Commitment. Amounts prepaid or repaid in respect of Tranche B Term Loans may not be reborrowed.

(d) Incremental Term Loans. In addition to Borrowings of Revolving Credit Loans, Tranche A Term Loans and Tranche B Term Loans pursuant to this Section, at any time and from time to time prior to the Term Loan Maturity Date for Tranche B Term Loans, the Borrower may request that one or more Persons (which may include any of the Lenders) offer to enter into commitments to make Incremental Term Loans to the Borrower hereunder; provided that (i) no Default would exist after giving pro forma effect to the intended use of proceeds of such Incremental Term Loans, (ii) it being understood that if such offer is to be made by any Person that is not already a Lender hereunder, the Administrative Agent shall have consented (such consent not to be unreasonably withheld) to such Person being a Lender hereunder to the extent such consent would be required pursuant to Section 10.04(b) in the event of an assignment to such Person and (iii) no Lender shall be obligated to agree to provide any Incremental Term Loan Commitments. In the event that one or more of such Persons offer, in their sole discretion, to enter into such commitments, and such Persons and the Borrower agree as to the amount of such commitments that shall be allocated to the respective Persons making such offers and the fees (if any) to be payable by the Borrower in connection therewith and the interest rate, amortization and maturity date to be applicable thereto, the Borrower, such Persons and the Administrative Agent shall execute and deliver an appropriate Incremental Term Loan Amendment with respect thereto, and such Persons shall become obligated to make Incremental Term Loans under this Agreement in an amount equal to the amount of their respective Incremental Term Loan Commitments as specified in such Incremental Term Loan Amendment. The Incremental Term Loans to be made pursuant to any such agreement between the Borrower and one or more Lenders in response to any such request by the Borrower shall be deemed to be a separate “Series” of Incremental Term Loans for all purposes of this Agreement. Amounts paid or prepaid in respect of Incremental Term Loans of any Series may not be reborrowed.

Anything herein to the contrary notwithstanding, the following additional provisions shall be applicable to the Incremental Term Loan Commitments, and Incremental Term Loans, of any Series:

(i) the minimum aggregate principal amount of Incremental Term Loan Commitments entered into pursuant to any such request (and, accordingly, the minimum aggregate principal amount of any Series of Incremental Term Loans) shall be $50,000,000;

(ii) the aggregate principal amount of all Incremental Term Loan Commitments and Incremental Term Loans shall not exceed $150,000,000;

(iii) the final maturity for the Incremental Term Loans of any Series shall not be earlier than the Term Loan Maturity Date for Tranche B Term Loans;

(iv) the weighted average life to maturity (determined in a manner reasonably satisfactory to the Administrative Agent) of the Incremental Term Loans of any Series at the time of the making thereof shall not be shorter than the then remaining weighted average life to maturity (so determined) of the Tranche B Term Loans; and

(v) except for the amortization and interest rate to be applicable thereto, and any fees to be paid in connection therewith, the Incremental Term Loans of any Series shall have the same terms as the Tranche B Term Loans.

(a) Obligations of Lenders. Each Loan shall be made as part of a Borrowing consisting of Loans of the same Class and Type made by the Lenders ratably in accordance with their respective Commitments of the applicable Class (and, in the case of Incremental Term Loans, of a particular Series). The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Type of Loans. Subject to Section 2.12, each Borrowing shall be constituted entirely of ABR Loans or of Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement and no such Affiliate shall be deemed to be a Lender hereunder for any purpose.

(c) Minimum Amounts; Limitation on Number of Borrowings. Each Eurodollar Borrowing shall be in an aggregate amount of $5,000,000 or a larger multiple of $500,000. Each ABR Borrowing shall be in an aggregate amount equal to $1,000,000 or a larger multiple thereof; provided that an ABR Borrowing may be in an aggregate amount (i) equal to the entire unused balance of the total Commitments of the applicable Class, (ii) in the case of an Incremental Term Loan Commitment of any Series, equal to the entire unused balance of the total Commitments of such Series) or (iii) in the case of a Revolving Credit ABR Borrowing, that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.04(f). Borrowings of more than one Class and Type may be outstanding at the same time; provided that there shall not at any time be more than a total of 15 Eurodollar Borrowings outstanding.

(d) Limitations on Interest Periods. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request (or to elect to convert to or continue as a Eurodollar Borrowing): (i) any Revolving Credit Borrowing if the Interest Period requested therefor would end after the Revolving Credit Commitment Termination Date; (ii) any Term Borrowing of any Class (including, in the case of any Incremental Term Borrowing, any Series thereof) if the Interest Period requested therefor would end after the Term Loan Maturity Date of such Class; or (iii) any Term Borrowing of any Class (including, in the case of any Incremental

Term Borrowing, any Series thereof) if the Interest Period requested therefor would commence before and end after any Principal Payment Date for such Term Borrowing unless, after giving effect thereto, the aggregate principal amount of the Term Loans of such Class having Interest Periods that end after such Principal Payment Date shall be equal to or less than the aggregate principal amount of the Term Loans of such Class permitted to be outstanding after giving effect to the payments of principal required to be made on such Principal Payment Date.

(a) Notice by the Borrower. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (i) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., New York City time, three Business Days before the date of the proposed Borrowing or (ii) in the case of an ABR Borrowing, not later than 1:00 p.m., New York City time, on the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by the Borrower.

(b) Content of Borrowing Requests. Each telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) whether the requested Borrowing is to be a Revolving Credit Borrowing or a Term Borrowing (including, if applicable, the respective Series of Incremental Term Loans to which such Borrowing relates);

(iv) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

(v) in the case of a Eurodollar Borrowing, the Interest Period therefor, which shall be a period contemplated by the definition of the term “Interest Period” and permitted under Section 2.02(d); and

(vi) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

(c) Notice by the Administrative Agent to the Lenders. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

(d) Failure to Elect. If no election as to the Type of a Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with

respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month.

(a) General. Subject to the terms and conditions set forth herein, in addition to the Loans provided for in Section 2.01, the Borrower may request any Issuing Lender to issue, at any time and from time to time during the Revolving Credit Availability Period, Letters of Credit for its own account in such form as is acceptable to such Issuing Lender in its reasonable determination. Letters of Credit issued hereunder shall constitute utilization of the Revolving Credit Commitments.

(b) Notice of Issuance, Amendment, Renewal or Extension. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the respective Issuing Lender) to an Issuing Lender selected by it and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (d) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the respective Issuing Lender, the Borrower also shall submit a letter of credit application on such Issuing Lender’s standard form in connection with any request for a Letter of Credit. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuing Lender relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(c) Limitations on Amounts. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the aggregate LC Exposure of all of the Issuing Lenders (determined for these purposes without giving effect to the participations therein of the Revolving Credit Lenders pursuant to paragraph (e) of this Section) shall not exceed $50,000,000 and (ii) the total Revolving Credit Exposures shall not exceed the total Revolving Credit Commitments.

(d) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the first anniversary of the date of the issuance of such Letter of Credit and (ii) the date that is five Business Days prior to the Revolving Credit Commitment Termination Date; provided that any Letter of Credit with a one-year term may provide for automatic renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (ii) above).

(e) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) by any Issuing Lender, and without any further action on the part of such Issuing Lender or the Lenders, such Issuing Lender hereby grants to each Revolving Credit Lender, and each Revolving Credit Lender hereby acquires from such Issuing Lender, a participation in such Letter of Credit equal to such Revolving Credit Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. Each Revolving Credit Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments.

In consideration and in furtherance of the foregoing, each Revolving Credit Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for account of the respective Issuing Lender, such Revolving Credit Lender’s Applicable Percentage of each LC Disbursement made by an Issuing Lender promptly upon the request of such Issuing Lender at any time from the time of such LC Disbursement until such LC Disbursement is reimbursed by the Borrower or at any time after any reimbursement payment is required to be refunded to the Borrower for any reason. Such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each such payment shall be made in the same manner as provided in Section 2.05 with respect to Loans made by such Revolving Credit Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Revolving Credit Lenders), and the Administrative Agent shall promptly pay to the respective Issuing Lender the amounts so received by it from the Revolving Credit Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to the next following paragraph, the Administrative Agent shall distribute such payment to the respective Issuing Lender or, to the extent that the Revolving Credit Lenders have made payments pursuant to this paragraph to reimburse such Issuing Lender, then to such Revolving Credit Lenders and such Issuing Lender as their interests may appear. Any payment made by a Revolving Credit Lender pursuant to this paragraph to reimburse an Issuing Lender for any LC Disbursement shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Reimbursement. If an Issuing Lender shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such Issuing Lender in respect of such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 1:00 p.m., New York City time, on (i) the Business Day that the Borrower receives notice of such LC Disbursement, if such notice is received prior to 11:00 a.m., New York City time, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time, provided that, if such LC Disbursement is not less than $1,000,000, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 that such payment be financed with a Revolving Credit ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Revolving Credit ABR Borrowing. If the Borrower fails to make such payment when due and shall not have requested a Revolving Credit ABR Borrowing in accordance with

Section 2.03, the Administrative Agent shall notify each Revolving Credit Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof.

(g) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (f) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the respective Issuing Lender under a Letter of Credit against presentation of a draft or other document that does not comply strictly with the terms of such Letter of Credit, (iv) any exchange, release or non-perfection of any Collateral or other collateral, or any release or waiver of, amendment to or consent to departure from the guarantee obligations of the Subsidiary Guarantors under Article III and (v) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of the Borrower’s obligations hereunder.

Neither the Administrative Agent, the Lenders nor any Issuing Lender, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit by the respective Issuing Lender or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the respective Issuing Lender; provided that the foregoing shall not be construed to excuse an Issuing Lender from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Lender’s gross negligence or willful misconduct when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that:

(i) an Issuing Lender may accept documents that appear on their face to be in substantial compliance with the terms of a Letter of Credit without responsibility for further investigation, regardless of any notice or information to the contrary, and may make payment upon presentation of documents that appear on their face to be in substantial compliance with the terms of such Letter of Credit;

(ii) an Issuing Lender shall have the right, in its sole discretion, to decline to accept such documents and to make such payment if such documents are not in strict compliance with the terms of such Letter of Credit; and

(iii) this sentence shall establish the standard of care to be exercised by an Issuing Lender when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof (and the parties hereto hereby waive, to the extent permitted by applicable law, any standard of care inconsistent with the foregoing).

(h) Disbursement Procedures. The Issuing Lender for any Letter of Credit shall, within a reasonable time following its receipt thereof, examine all documents purporting to represent a demand for payment under such Letter of Credit. Such Issuing Lender shall promptly after such examination notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuing Lender has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Lender and the Lenders with respect to any such LC Disbursement.

(i) Interim Interest. If the Issuing Lender for any Letter of Credit shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (f) of this Section, then Section 2.11(c) shall apply. Interest accrued pursuant to this paragraph shall be for account of such Issuing Lender, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (f) of this Section to reimburse such Issuing Lender shall be for account of such Lender to the extent of such payment.

(j) Replacement of an Issuing Lender. Any Issuing Lender may be replaced at any time by written agreement between the Borrower, the Administrative Agent, the replaced Issuing Lender and the successor Issuing Lender. The Administrative Agent shall notify the Lenders of any such replacement of an Issuing Lender. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for account of the replaced Issuing Lender pursuant to Section 2.10(b). From and after the effective date of any such replacement, (i) the successor Issuing Lender shall have all the rights and obligations of the replaced Issuing Lender under this Agreement with respect to Letters of Credit to be issued by it thereafter and (ii) references herein to the term “Issuing Lender” shall be deemed to include such successor or any previous Issuing Lender, or such successor and all previous Issuing Lenders, as the context shall require. After the replacement of an Issuing Lender hereunder, the replaced Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(k) Cash Collateralization. If either (i) an Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing more than 50% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this Section 2.04(k), or (ii) the Borrower shall be required to provide cover for

LC Exposure pursuant to Section 2.09(b), the Borrower shall immediately deposit into the Collateral Account under (and as defined in) the Security Agreement (or, at any time following the termination of the Security Agreement, a cash collateral account maintained by the Administrative Agent at a banking institution selected by the Administrative Agent, on substantially the same terms of Section 5 of Security Agreement, as in effect immediately prior to such termination) an amount in immediately available funds equal to, in the case of an Event of Default, the LC Exposure as of such date plus any accrued and unpaid interest thereon and, in the case of cover pursuant to Section 2.09(b), the amount required under Section 2.09(b); provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (h) or (i) of Article VIII. Such deposit shall be held by the Collateral Agent in such collateral account as collateral in the first instance for the LC Exposure under this Agreement and thereafter, until such time as the Security Release has occurred, for the payment of the other Secured Obligations, and for these purposes the Borrower hereby grants a security interest to the Collateral Agent for the benefit of the Lenders in such collateral account and in any financial assets (as defined in the Uniform Commercial Code) or other property held therein. Following the termination of the Security Agreement pursuant to the Security Release, if the Borrower is required to provide cash collateral pursuant to clause (i) of this Section 2.04(k), so long as no Event of Default has occurred and is continuing, upon the request of the Borrower any amounts held in such collateral account (to the extent not theretofore applied to the LC Exposure) shall be returned to the Borrower.

(l) Reports by Issuing Lenders to Administrative Agent. On the Business Day following each Quarterly Date, each Issuing Lender shall furnish to the Administrative Agent a report setting forth (i) the issuance and expiration dates, and the face amount, of each Letter of Credit issued by such Issuing Lender during the most recently completed fiscal quarter, (ii) the aggregate undrawn amount of all Letters of Credit issued by such Issuing Lender that are outstanding as of such date and (iii) the aggregate amount of all LC Disbursements made by such Issuing Lender that have not been reimbursed by or on behalf of the Borrower prior to such date.

(m) Existing Letters of Credit. Subject to the terms and conditions hereof, each letter of credit issued by an Issuing Lender as an issuing bank under the Existing PacifiCare Credit Agreement that is outstanding on the Effective Date and designated to be continued hereunder in Schedule 2.04(m) shall automatically be continued hereunder on the Effective Date, and as of the Effective Date the Revolving Credit Lenders shall acquire a participation therein as if such letter of credit were issued hereunder, and each such letter of credit shall be deemed a Letter of Credit for all purposes of this Agreement as of the Effective Date.

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon (or in the case of same day ABR Borrowings, 3:30 p.m.), New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by

promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request; provided that Revolving Credit ABR Borrowings made to finance the reimbursement of an LC Disbursement as provided in Section 2.04(f) shall be remitted by the Administrative Agent to the respective Issuing Lender.

(b) Presumption by the Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption (but in its sole discretion), make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender agrees to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower and the Borrower agrees to pay the Administrative Agent forthwith such corresponding amount together with interest thereon at the interest rate applicable to ABR Loans for each day from and including the date such amount was made available to the Borrower to but excluding the date of payment to the Administrative Agent. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. Nothing in this paragraph shall be deemed to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender hereunder.

(a) Elections by the Borrower. The Loans constituting each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have the Interest Period specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a Borrowing of a different Type or to continue such Borrowing as a Borrowing of the same Type and, in the case of a Eurodollar Borrowing, may elect the Interest Period therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans constituting such Borrowing, and the Loans constituting each such portion shall be considered a separate Borrowing.

(b) Notice of Elections. To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be

confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Content of Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies (including, if applicable, the respective Series of Incremental Term Loans to which such Interest Request relates) and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) of this paragraph shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period therefor after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period” and permitted under Section 2.02(d).

(d) Notice by the Administrative Agent to the Lenders. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) Failure to Elect; Events of Default. If the Borrower fails to deliver a timely and complete Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period therefor, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period the Borrower shall be deemed to have selected an Interest Period of one month. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period therefor.

(a) Scheduled Termination. Unless previously terminated, (i) the Revolving Credit Commitments shall terminate on the Revolving Credit Commitment Termination Date, (ii) the Tranche A Term Loan Commitments shall terminate at 5:00 p.m., New York City time, on the Effective Date, (iii) the Tranche B Term Loan Commitments shall terminate at 5:00 p.m., New York City time, on the Effective Date and (iv) the Incremental Term Loan Commitments of

each Series shall terminate at 5:00 p.m., New York City time, on the date specified therefor pursuant to Section 2.01(d) at the time such Series is established.

(b) Voluntary Termination or Reduction. The Borrower may at any time terminate in whole, or from time to time reduce in part, the Commitments of any Class (including the Commitments of any Series of Incremental Term Loans); provided that (i) each reduction of the Commitments of any Class pursuant to this Section shall be in an amount that is $2,000,000 or a larger multiple of $1,000,000 and (ii) the Borrower shall not terminate or reduce the Revolving Credit Commitments if, after giving effect to any concurrent prepayment of the Revolving Credit Loans in accordance with Section 2.09, the total Revolving Credit Exposures would exceed the total Revolving Credit Commitments.

(c) Notice of Voluntary Termination or Reduction. The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments of any Class under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable.

(d) Effect of Termination or Reduction. Any termination or reduction of the Commitments of any Class shall be permanent. Each reduction of the Commitments of any Class shall be made ratably among the Lenders in accordance with their respective Commitments of such Class.

(a) Repayment. The Borrower hereby unconditionally promises to pay the Loans as follows:

(i) to the Administrative Agent for account of the Revolving Credit Lenders the outstanding principal amount of the Revolving Credit Loans on the Revolving Credit Commitment Termination Date,

(ii) to the Administrative Agent for account of the Tranche A Term Loan Lenders the aggregate principal amount of the Tranche A Term Loans on each Principal Payment Date set forth below in the aggregate principal amount set forth opposite such Principal Payment Date (subject to adjustment pursuant to paragraph (b) of this Section):

(iii) to the Administrative Agent for account of the Tranche B Term Loan Lenders the aggregate principal amount of the Tranche B Term Loans on each Principal Payment Date set forth below in the aggregate principal amount set forth opposite such Principal Payment Date (subject to adjustment pursuant to paragraph (b) of this Section):

(iv) to the Administrative Agent for the account of the Incremental Term Loan Lenders of any Series the outstanding principal amount of the Incremental Term Loans of such Series in such installments, on such dates and in such amounts as shall be agreed upon between the Borrower and such Incremental Term Loan Lenders at the time the Incremental Term Loan Commitments of such Series are established pursuant to Section 2.01(d).

(b) Adjustment of Amortization Schedule. Any prepayment of a Term Borrowing of any Class (including, in the case of any Incremental Term Borrowing, any Series thereof) shall be applied to reduce the subsequent scheduled principal installments of the Term Borrowings to be made pursuant to this Section (i) ratably, in the case of a prepayment made pursuant to Section 2.09(b), or (ii) in direct order of maturity, in the case of any other prepayment. To the extent not previously paid, all Term Loans shall be due and payable on the respective Term Loan Maturity Dates.

(c) Manner of Payment. Prior to any repayment of any Borrowings of any Class hereunder (other than the payment in full of all outstanding Borrowings of any Class on the scheduled date of such repayment), the Borrower shall select the Borrowing or Borrowings of the applicable Class to be paid and shall notify the Administrative Agent by telephone (confirmed by telecopy) of such selection not later than 1:00 p.m., New York City time, three Business Days in the case of any repayment of Eurodollar Borrowings and one Business Day in the case of any repayment of ABR Borrowings, in each case before the scheduled date of such repayment; provided that each repayment of Borrowings of any Class shall be applied to repay any outstanding ABR Borrowings of such Class before any other Borrowings of such Class. If the Borrower fails to make a timely selection of the Borrowing or Borrowings to be repaid (in accordance with the immediately preceding sentence) or prepaid (in accordance with Section 2.09(c)), such payment shall be applied, first, to pay any outstanding ABR Borrowings of the applicable Class and, second, to other Borrowings of such Class in the order of the remaining duration of their respective Interest Periods (the Borrowing with the shortest

remaining Interest Period to be repaid first). Each payment of a Borrowing shall be applied ratably to the Loans included in such Borrowing.

(d) Maintenance of Records by Lenders. Each Lender shall maintain in accordance with its usual practice records evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(e) Maintenance of Records by the Administrative Agent. The Administrative Agent shall maintain records in which it shall record (i) the amount of each Loan made hereunder, the Class and Type thereof (and, in the case of Incremental Term Loans, the respective Series thereof) and each Interest Period therefor, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for account of the Lenders and each Lender’s share thereof.

(f) Effect of Entries. The entries made in the records maintained pursuant to paragraph (d) or (e) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such records or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(g) Promissory Notes. Any Lender may request that Loans of any Class made by it be evidenced by a promissory note. In such event, the Borrower shall execute and deliver to such Lender a promissory note payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) in the form of Exhibit F-1 (in the case of Revolving Credit Loans), Exhibit F-2 (in the case of Tranche A Term Loans) or Exhibit F-3 (in the case of Tranche B Term Loans or, with such changes to such form as the Borrower and the Administrative Agent shall agree upon, in the case of Incremental Term Loans of any Series), as applicable, or such other form reasonably approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be represented by one or more promissory notes in such form payable to the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

(i) The Borrower shall have the right at any time and from time to time to prepay any Borrowing of any Class in whole or in part, subject to the requirements of this Section. Any prepayment of Term Loans of any Class pursuant to this Section 2.09(a)(i) shall be applied to the remaining installments of such Term Loans in the direct order of maturity.

(ii) In connection with the Security Release only, the Borrower shall have the right to prepay, or offer to prepay, in full the Tranche B Term Loans and the Incremental Term

Loans then outstanding in accordance with this Section, provided that, if the Borrower shall elect to make an offer to prepay such Loans, the Borrower will give the Administrative Agent telephonic notice thereof (promptly confirmed in writing) requesting that the Administrative Agent prepare and provide to each Tranche B Term Loan Lender and Incremental Term Loan Lender a notice (each, a “Prepayment Option Notice”) as described below. As promptly as practicable after receiving such notice from the Borrower, the Administrative Agent will send to each Tranche B Term Loan Lender and Incremental Term Loan Lender a Prepayment Option Notice, which shall be in the form of Exhibit G, and shall include an offer by the Borrower to prepay in full, on a date (the “Specified Prepayment Date”) that is not less than 10 Business Days after the date of the Prepayment Option Notice, the relevant Term Loans of each such Term Loan Lender. Each Tranche B Term Loan Lender and each Incremental Term Loan Lender shall notify the Administrative Agent at least three Business Days prior to the Specified Prepayment Date of its decision to accept or reject such prepayment, and the Administrative Agent shall notify the Borrower thereof no later than two Business Days prior to the Specified Prepayment Date (and any such Term Loan Lender failing to so notify the Administrative Agent shall be deemed to have accepted such prepayment). On the Specified Prepayment Date, the Borrower shall pay to the Administrative Agent for account of the relevant Tranche B Term Loans Lenders and Incremental Term Loan Lenders the aggregate amount necessary to prepay that portion of the outstanding Tranche B Term Loans and Incremental Term Loans, respectively, in respect of which such Term Loan Lenders have (or are deemed to have) accepted prepayment as described above.

(b) Mandatory Prepayments. The Borrower will prepay the Loans (and/or provide cover for LC Exposure as specified in Section 2.04(k)), and/or the Commitments shall be subject to automatic reduction, as follows:

(i) Dispositions and Recovery Events. If the Borrower or any of its Subsidiaries shall receive Net Available Proceeds from any Disposition or any Recovery Event after the Effective Date (x) in excess of $25,000,000 or (y) which, when combined with the Net Available Proceeds of all other prior Dispositions and Recovery Events occurring after the Effective Date as to which a prepayment has not yet been made under this paragraph (i) (but not including for this purpose Excluded Dispositions and any Disposition or Recovery Event as to which a Reinvestment Notice shall have been given), are in excess of $50,000,000 in the aggregate during any fiscal year of the Borrower, then the Borrower will prepay the Loans (and/or provide cover for LC Exposure as specified in Section 2.04(k)), and the Commitments shall be subject to automatic reduction, in an aggregate amount equal to (A) in the case of clause (x) above, the portion of the Net Available Proceeds of such Disposition or Recovery Event, as the case may be, in excess of $25,000,000 or (B) in the case of clause (y) above, the portion of the Net Available Proceeds of such Disposition or Recovery Event, as the case may be, and such prior Dispositions and Recovery Events in excess of $50,000,000 for the relevant fiscal year, such prepayment and/or reduction to be effected in each case in the manner and to the extent specified in paragraph (iii) of this Section, provided that:

(A) notwithstanding the foregoing, the Borrower shall not be required to make any prepayment or reduce any Commitments under this paragraph (i) if

(I) on or prior to the date of receipt of the Net Available Proceeds from the relevant Disposition or Recovery Event, the Borrower shall have delivered a Reinvestment Notice with respect thereto to the Administrative Agent, (II) such Disposition is an Excluded Disposition or (III) such Disposition or Recovery Event occurs after the Security Release;

(B) subject to clause (A) above, on each Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event shall be applied in the manner and to the extent specified in paragraph (iii) of this Section; and

(C) no later than five Business Days prior to the anticipated occurrence of any Disposition (other than any Excluded Disposition) or Recovery Event or, if the Borrower shall deliver a Reinvestment Notice with respect to such Disposition or Recovery Event as provided above, no later than five Business Days after the occurrence of such Disposition or Recovery Event, the Borrower will deliver to the Administrative Agent a statement of a Financial Officer, in form and detail satisfactory to the Administrative Agent, setting forth the amount of the Net Available Proceeds of such Disposition or Recovery Event (or, in the case of any such statement delivered prior to the occurrence of such Disposition or Recovery Event, the anticipated amount of the Net Available Proceeds of such Disposition or Recovery Event) and of all such prior Dispositions and Recovery Events during the same fiscal year (excluding Excluded Dispositions and any Disposition or Recovery Event as to which a Reinvestment Notice shall have been given).

(ii) Debt Incurrence. Upon any Debt Incurrence, the Borrower shall prepay the Term Loans in an aggregate amount equal to 50% of the Net Available Proceeds thereof, such prepayment to be effected in each case in the manner and to the extent specified in paragraph (iii) of this Section, provided that, notwithstanding the foregoing, the Borrower shall not be required to make a prepayment under this paragraph (ii) if (I) such Debt Incurrence is an Excluded Debt Incurrence or (II) such Debt Incurrence occurs after the Security Release.

(iii) Application. Prepayments and/or reductions of Commitments pursuant to this Section 2.09(b) shall be applied, first, to prepay the Term Loans and, second (but only in the case of paragraph (i) above), after the payment in full of the Term Loans, to reduce the aggregate amount of the Revolving Credit Commitments (and to the extent that, after giving effect to such reduction, the total Revolving Credit Exposures would exceed the total Revolving Credit Commitments, first, to prepay Revolving Credit Loans and, second, to provide cover for LC Exposure as specified in Section 2.04(k) in an aggregate amount equal to such excess). Each such prepayment of the Term Loans shall be applied ratably to the respective Term Loans of each Class (including, in the case of Incremental Term Loans, to each Series thereof) in accordance with the respective outstanding principal amounts thereof and, in the case of each such Class of Term Loans, ratably to the then remaining installments thereof.

(c) Notices, Etc. The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 1:00 p.m., New York City time, three Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than 1:00 p.m., New York City time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount of each Borrowing or portion thereof to be prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the relevant Lenders of the contents thereof. Each optional partial prepayment of any Borrowing shall be in an aggregate amount of $2,000,000 or a larger multiple of $1,000,000. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.11 and shall be made in the manner specified in Section 2.08(c).

(a) Commitment Fee. The Borrower agrees to pay to the Administrative Agent for account of each Lender a commitment fee, which shall accrue at the Applicable Rate on the average daily unused amount of the Revolving Credit Commitment of such Lender during the period from and including the Effective Date to but excluding the earlier of the date such Revolving Credit Commitment terminates and the Revolving Credit Commitment Termination Date. Commitment fees accrued through and including each Quarterly Date shall be payable on the third Business Day following such Quarterly Date and on the earlier of the date the Revolving Credit Commitments terminate and the Revolving Credit Commitment Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of computing commitment fees, the Revolving Credit Commitment of a Lender shall be deemed to be used to the extent of the outstanding Revolving Credit Loans and LC Exposure of such Lender.

(b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent for account of each Revolving Credit Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at a rate per annum equal to the Applicable Rate applicable to interest on Revolving Credit Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Revolving Credit Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the respective Issuing Lender a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Revolving Credit Commitments and the date on which there ceases to be any LC Exposure, as well as such Issuing Lender’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including each

Quarterly Date shall be payable on the third Business Day following such Quarterly Date, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Revolving Credit Commitments terminate and any such fees accruing after the date on which the Revolving Credit Commitments terminate shall be payable on demand. Any other fees payable to any Issuing Lender pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) Agent Fees. The Borrower agrees to pay to each Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and such Agent.

(d) Payment of Fees. All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the respective Issuing Lender, in the case of fees payable to it) for distribution, in the case of facility fees and participation fees, to the Lenders entitled thereto. Fees paid shall not be refundable under any circumstances.

(a) ABR Loans. The Loans constituting each ABR Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate.

(b) Eurodollar Loans. The Loans constituting each Eurodollar Borrowing shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period for such Borrowing plus the Applicable Rate.

(c) Default Interest. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration, by mandatory prepayment or otherwise, (i) each outstanding Loan shall bear interest at a rate per annum equal to 2% plus the rate otherwise applicable to such Loan as provided above and (ii) such overdue amount (other than overdue principal on any Loan) shall bear interest, after as well as before judgment, at a rate per annum equal to 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d) Payment of Interest. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Credit Loans, upon termination of the Revolving Credit Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of a Revolving Credit Loan that is an ABR Loan prior to the Revolving Credit Commitment Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Borrowing prior to the end of the Interest Period therefor, accrued interest on such Borrowing shall be payable on the effective date of such conversion.

(e) Computation. All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.12. Alternate Rate of Interest. If prior to the commencement of the Interest Period for any Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or

(b) if such Borrowing is of a particular Class of Loans (including of a particular Series of Incremental Term Loans), the Administrative Agent is advised by the Required Lenders of such Class (or Series, if applicable) that the Adjusted LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their respective Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or the continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and such Borrowing (unless prepaid) shall be continued as, or converted to, an ABR Borrowing and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any Issuing Lender; or

(ii) impose on any Lender or any Issuing Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lenders of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or such Issuing Lender of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or such Issuing Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or such Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or any Issuing Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Lender’s capital or on the capital of such Lender’s or such Issuing Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Lender, to a level below that which such Lender or such Issuing Lender or such Lender’s or such Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Lender’s policies and the policies of such Lender’s or such Issuing Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Lender or such Lender’s or such Issuing Lender’s holding company for any such reduction suffered.

(c) Certificates from Lenders. A certificate of a Lender or an Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or such Issuing Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Lender, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or any Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or an Issuing Lender pursuant to this Section for any increased costs or reductions incurred more than six months prior to the date that such Lender or the Issuing Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.14. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period therefor (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of an Interest Period therefor, (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of

whether such notice is permitted to be revocable under Section 2.09(c) and is revoked in accordance herewith), or (d) the assignment as a result of a request by the Borrower pursuant to Section 2.17(b) of any Eurodollar Loan other than on the last day of an Interest Period therefor, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount determined by such Lender to be equal to the excess, if any, of (i) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii) the amount of interest that such Lender would earn on such principal amount for such period if such Lender were to invest such principal amount for such period at the interest rate that would be bid by such Lender (or an affiliate of such Lender) for Dollar deposits from other banks in the eurodollar market at the commencement of such period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Agent, Lender or Issuing Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by the Borrower. The Borrower shall indemnify each Agent, each Lender and each Issuing Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by such Agent, such Lender or such Issuing Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to

the Borrower by a Lender or an Issuing Lender, or by an Agent on its own behalf or on behalf of a Lender or an Issuing Lender, shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Foreign Lenders. (i) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(ii) Each Foreign Lender shall deliver to Administrative Agent and to the Borrower, on or prior to the Effective Date (in the case of each Lender party to this Agreement on such date) or on or prior to the effective date of the Assignment and Assumption pursuant to which it becomes a Lender (in the case of each other Lender), and at such other times as may be necessary in the determination of the Borrower or Administrative Agent (each in the reasonable exercise of its discretion), two original copies of Internal Revenue Service Form W-8BEN or W-8ECI (or any successor forms) properly completed and duly executed by such Lender, or, in the case of a Foreign Lender claiming exemption from United States federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest,” a form W-8BEN, and, in the case of a Lender that has certified in writing to Administrative Agent that it is not a “bank” (as defined in Section 881(c)(3)(A) of the Code), a certificate of such Lender certifying that such Lender is not (i) a “bank” for purposes of Section 881(c) of the Code, (ii) a ten-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower or (iii) a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Code) in each case together with any other certificate or statement of exemption required under the Code or the regulations issued thereunder to establish that such Lender is not subject to United States withholding tax with respect to any payments to such Lender of interest payable under any of the Loan Documents.

(iii) Each Foreign Lender hereby agrees, from time to time after the initial delivery by such Lender of such forms, whenever a lapse in time or change in circumstances renders such forms, certificates or other evidence so delivered obsolete or inaccurate in any material respect, that such Lender shall promptly (A) deliver to Administrative Agent and to the Borrower two original copies of renewals, amendments or additional or successor forms, properly completed and duly executed by such Lender, together with any other certificate or statement of exemption required in order to confirm or establish that such Lender is not subject to United States withholding tax with respect to payments to such Lender under the Loan Documents and, if applicable, that such Lender does not act for its own account with respect to

any portion of such payment, or (B) notify Administrative Agent and the Borrower of its inability to deliver any such forms, certificates or other evidence.

(iv) The Borrower shall not be required to pay any additional amount to any Foreign Lender under this paragraph (e), (A) with respect to any Tax required to be deducted or withheld on the basis of the information, certificates or statements of exemption such Lender chooses to transmit with an Internal Revenue Service Form W-8IMY pursuant to this paragraph (e) or (B) if such Lender shall have failed to satisfy the requirements of this paragraph (e); provided that if such Lender shall have satisfied the requirements of this paragraph (e) on the date such Lender became a Lender, nothing in this paragraph (e) shall relieve the Borrower of its obligation to pay any amounts pursuant to this paragraph (e) in the event that, as a result of any change in any applicable law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof, such Lender is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing the fact that such Lender is not subject to withholding hereunder.

(f) Tax Refunds. If an Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the Borrower, upon the request of such Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Agent or such Lender in the event such Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require any Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

(a) Payments by the Obligors. Each Obligor shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or under Section 2.13, 2.14 or 2.15, or otherwise) or under any other Loan Document (except to the extent otherwise provided therein) prior to 1:00 p.m., New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except as otherwise expressly provided in the relevant Loan Document and except for payments to be made directly to an Issuing Lender as expressly provided herein and payments pursuant to Sections 2.13, 2.14, 2.15 and 10.03, which shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for account of any other Person to the appropriate recipient

promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder or under any other Loan Document (except to the extent otherwise provided therein) shall be made in Dollars.

(b) Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, to pay principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Borrowing of a particular Class shall be made from the relevant Lenders, each payment of commitment fee under Section 2.10 shall be made for account of the relevant Lenders, and each termination or reduction of the amount of the Commitments of a particular Class under Section 2.07 shall be applied to the respective Commitments of such Class of the relevant Lenders, pro rata according to the amounts of their respective Commitments of such Class; (ii) each Borrowing of any Class shall be allocated pro rata among the relevant Lenders according to the amounts of their respective Commitments of such Class (in the case of the making of Loans) or their respective Loans of such Class that are to be included in such Borrowing (in the case of conversions and continuations of Loans); (iii) each payment or prepayment of principal of Loans of a particular Class by the Borrower shall be made for account of the relevant Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans of such Class held by them; and (iv) each payment of interest on Loans of a particular Class (including of a particular Series of Incremental Term Loans) by the Borrower shall be made for account of the relevant Lenders pro rata in accordance with the amounts of interest on Loans of such Class then due and payable to the respective Lenders.

(d) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon then due than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by any Obligor pursuant to and in accordance with the express terms of this

Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). Each Obligor consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Obligor rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Obligor in the amount of such participation.

(e) Presumptions of Payment. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for account of the Lenders or an Issuing Lender hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption (but in its sole discretion), distribute to the Lenders or such Issuing Lender, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or such Issuing Lender, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate.

(f) Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(e), 2.05(b) or 2.16(e), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.13, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for account of any Lender pursuant to Section 2.15;

(iii) a Revolving Credit Lender defaults in its obligations to make a Revolving Credit Loan; or

(iv) any Lender declines to consent to any amendment, modification or waiver of this Agreement or any other Loan Document that pursuant to Section 10.02 requires consent of 100% of the Lenders (or, as applicable, 100% of the Lenders of any Class in which such Lender holds Loans and/or a Commitment), provided that such amendment, modification or waiver has received approval by Lenders constituting the Required Lenders (or the Required Lenders of such Class, as applicable),

then the Borrower shall have the right, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, to replace such Lender by causing such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04 and pursuant to an Assignment and Assumption), its Commitments, Loans and LC Exposure (if any) to one or more assignees identified by the Borrower (which may include another Lender at the time, if such other Lender accepts such assignment); provided that (x) the assignee or assignees shall be approved by the Administrative Agent (and, if a Revolving Credit Commitment is being assigned, by each Issuing Lender), which approval shall not unreasonably be withheld or delayed, (y) the Lender being so replaced shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts then payable to such Lender hereunder, from the assignee(s) (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments payable by the Borrower. No Lender shall be required to make any such assignment and delegation under this Section if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation shall cease to apply.

SECTION 3.01. The Guarantee. The Subsidiary Guarantors hereby jointly and severally guarantee to each Lender and each Agent and their respective successors and assigns the prompt payment in full when due (whether at stated maturity, by acceleration or otherwise) of the principal of and interest on the Loans made by the Lenders to the Borrower and all other amounts from time to time owing to the Lenders or the Agents by the Borrower under this Agreement and by any Obligor under any of the other Loan Documents, in each case strictly in

accordance with the terms thereof (such obligations being herein collectively called the “Guaranteed Obligations”). The Subsidiary Guarantors hereby further jointly and severally agree that if the Borrower shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the Subsidiary Guarantors will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal.

SECTION 3.02. Obligations Unconditional. The obligations of the Subsidiary Guarantors under Section 3.01 are absolute and unconditional, joint and several, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of the Borrower under this Agreement or any other agreement or instrument referred to herein, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section that the obligations of the Subsidiary Guarantors hereunder shall be absolute and unconditional, joint and several, under any and all circumstances (except for (i) payment in full of the Guaranteed Obligations and (ii) with respect to any Subsidiary Guarantor, the release of such Subsidiary Guarantor from its obligations under this Article III in accordance with the terms hereof). Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Subsidiary Guarantors hereunder, which shall remain absolute and unconditional as described above:

(i) at any time or from time to time, without notice to the Subsidiary Guarantors, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;

(ii) any of the acts mentioned in any of the provisions of this Agreement or any other agreement or instrument referred to herein shall be done or omitted;

(iii) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be modified, supplemented or amended in any respect, or any right under this Agreement or any other agreement or instrument referred to herein shall be waived or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with; or

(iv) any lien or security interest granted to, or in favor of, either Agent or any Lender or Lenders as security for any of the Guaranteed Obligations shall fail to be perfected.

The Subsidiary Guarantors hereby expressly waive diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that either Agent or any Lender exhaust any right, power or remedy or proceed against the Borrower under this Agreement or any other

agreement or instrument referred to herein, or against any other Person under any other guarantee of, or security for, any of the Guaranteed Obligations.

SECTION 3.03. Reinstatement. The obligations of the Subsidiary Guarantors under this Article shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of the Borrower in respect of the Guaranteed Obligations is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and the Subsidiary Guarantors jointly and severally agree that they will indemnify each Agent and each Lender on demand for all reasonable costs and expenses (including fees of counsel) incurred by such Agent or such Lender in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

SECTION 3.04. Subrogation. The Subsidiary Guarantors hereby jointly and severally agree that until the payment and satisfaction in full of all Guaranteed Obligations and the expiration and termination of the Commitments of the Lenders under this Agreement they shall not exercise any right or remedy arising by reason of any performance by them of their guarantee in Section 3.01, whether by subrogation or otherwise, against the Borrower or any other guarantor of any of the Guaranteed Obligations or any security for any of the Guaranteed Obligations.

SECTION 3.05. Remedies. The Subsidiary Guarantors jointly and severally agree that, as between the Subsidiary Guarantors and the Lenders, the obligations of the Borrower under this Agreement may be declared to be forthwith due and payable as provided in Article VIII (and shall be deemed to have become automatically due and payable in the circumstances provided in Article VIII) for purposes of Section 3.01 notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against the Borrower and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by the Borrower) shall forthwith become due and payable by the Subsidiary Guarantors for purposes of Section 3.01.

SECTION 3.06. Instrument for the Payment of Money. Each Subsidiary Guarantor hereby acknowledges that the guarantee in this Article constitutes an instrument for the payment of money, and consents and agrees that any Lender or either Agent, at its sole option, in the event of a dispute by such Subsidiary Guarantor in the payment of any moneys due hereunder, shall have the right to bring motion-action under New York CPLR Section 3213.

SECTION 3.07. Continuing Guarantee. The guarantee in this Article is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising.

SECTION 3.08. Rights of Contribution. The Subsidiary Guarantors hereby agree, as between themselves, that if any Subsidiary Guarantor shall become an Excess Funding Guarantor (as defined below) by reason of the payment by such Subsidiary Guarantor of any

Guaranteed Obligations, each other Subsidiary Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the next sentence), pay to such Excess Funding Guarantor an amount equal to such Subsidiary Guarantor’s Pro Rata Share (as defined below and determined, for this purpose, without reference to the properties, debts and liabilities of such Excess Funding Guarantor) of the Excess Payment (as defined below) in respect of such Guaranteed Obligations. The payment obligation of a Subsidiary Guarantor to any Excess Funding Guarantor under this Section shall be subordinate and subject in right of payment to the prior payment in full of the obligations of such Subsidiary Guarantor under the other provisions of this Article and such Excess Funding Guarantor shall not exercise any right or remedy with respect to such excess until payment and satisfaction in full of all of such obligations.

For purposes of this Section, (i) “Excess Funding Guarantor” means, in respect of any Guaranteed Obligations, a Subsidiary Guarantor that has paid an amount in excess of its Pro Rata Share of such Guaranteed Obligations, (ii) “Excess Payment” means, in respect of any Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro Rata Share of such Guaranteed Obligations and (iii) “Pro Rata Share” means, for any Subsidiary Guarantor, the ratio (expressed as a percentage) of (x) the amount by which the aggregate present fair saleable value of all properties of such Subsidiary Guarantor (excluding any shares of stock of any other Subsidiary Guarantor) exceeds the amount of all the debts and liabilities of such Subsidiary Guarantor (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of such Subsidiary Guarantor hereunder and any obligations of any other Subsidiary Guarantor that have been Guaranteed by such Subsidiary Guarantor) to (y) the amount by which the aggregate fair saleable value of all properties of all of the Subsidiary Guarantors exceeds the amount of all the debts and liabilities (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of the Borrower and the Subsidiary Guarantors hereunder and under the other Loan Documents) of all of the Subsidiary Guarantors, determined (A) with respect to any Subsidiary Guarantor that is a party hereto on the Effective Date, as of the Effective Date, and (B) with respect to any other Subsidiary Guarantor, as of the date such Subsidiary Guarantor becomes a Subsidiary Guarantor hereunder.

SECTION 3.09. General Limitation on Guarantee Obligations. In any action or proceeding involving any state corporate law, or any state or Federal bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under Section 3.01 would otherwise, taking into account the provisions of Section 3.08, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under Section 3.01, then, notwithstanding any other provision hereof to the contrary, the amount of such liability shall, without any further action by such Subsidiary Guarantor, any Lender, either Agent or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

SECTION 3.10. Release of Subsidiary Guarantor. In the event that all of the Equity Interests held by the Borrower or its Subsidiaries in any Subsidiary Guarantor is sold or otherwise disposed of (except as permitted under Section 7.03(a)(ii) or in connection with the enforcement of the Security Documents by the Collateral Agent) or dissolved or liquidated in

compliance with the requirements of this Agreement (or such sale, other disposition, dissolution or liquidation has been approved by the Required Lenders) and the proceeds thereof have been applied to the extent required under Section 2.09(b)(i), such Subsidiary Guarantor shall, without further action, automatically be released from the Guarantee in this Article and the Guaranteed Obligations and the Guarantee in this Article shall, as to such Subsidiary Guarantor, terminate and have no further force or effect (it being understood and agreed that the sale of Equity Interests in one or more Persons that own, directly or indirectly, all of such Equity Interests in any Subsidiary Guarantor shall be deemed to be a sale of such Equity Interests in such Subsidiary Guarantor for the purposes of this Section).

The Borrower represents and warrants to the Agents and the Lenders (with references herein to the Subsidiaries being references thereto after giving effect to the AMS Acquisition (except as used in Section 4.04(a)), provided that such representations and warranties as of the Effective Date insofar as they relate to AMS and its Subsidiaries are made by the Borrower only to the best of its knowledge) that:

SECTION 4.02. Authorization; Enforceability. The Transactions are within each Obligor’s corporate powers and have been duly authorized by all necessary corporate and, if required, by all necessary shareholder action.

then, and in every such event (other than an event with respect to any Obligor described in clause (h) or (i) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Required Lenders shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii) declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Obligors accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by each Obligor; and in case of any

event with respect to any Obligor described in clause (h) or (i) of this Article, the Commitments shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Obligors accrued hereunder, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by each Obligor.

Each of the Lenders and the Issuing Lenders hereby irrevocably appoints each Agent as its agent hereunder and under the other Loan Documents and authorizes each Agent to take such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto.

Each of the Person serving as the Administrative Agent hereunder and the Person serving as the Collateral Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent or the Collateral Agent, as the case may be, and such Person and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent or the Collateral Agent, as the case may be, hereunder.

Neither Agent shall have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, (a) neither Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) neither Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that such Agent is required to exercise in writing by the Required Lenders (or, to the extent required by this Agreement or any other Loan Document, all of the Lenders or such other specified percentage or number of Lenders), and (c) except as expressly set forth herein and in the other Loan Documents, neither Agent shall have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or as Collateral Agent or any of its Affiliates in any capacity. Neither Agent shall be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or, to the extent required by this Agreement or any other Loan Document, all of the Lenders or such other specified percentage or number of Lenders) or in the absence of its own gross negligence or willful misconduct. Each Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to such Agent by the Borrower or a Lender, and neither Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document,

(ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein or therein, other than to confirm receipt of items expressly required to be delivered to such Agent.

Each Agent shall be entitled to rely upon, and neither Agent shall incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. Each Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. Each Agent may consult with legal counsel (who may be counsel for an Obligor), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Each Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by such Agent. Each Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of such Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent or Collateral Agent, as applicable.

Either Agent may resign at any time by notifying the Lenders, the Issuing Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor which shall be a bank (or any Affiliate thereof) with an office in the United States. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent’s resignation shall nonetheless become effective and (1) the retiring Agent shall be discharged from its duties and obligations hereunder and (2) the Required Lenders shall perform the duties of such Agent (and all payments and communications provided to be made by, to or through such Agent shall instead be made by or to each Lender directly) until such time as the Required Lenders appoint a successor agent as provided for above in this paragraph. Upon the acceptance of its appointment as Agent hereunder by a successor and, in the case of a successor Collateral Agent, upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Security Documents, and such other instruments or notices, as may be necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Security Documents, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder (if not already discharged therefrom as provided above in this paragraph).

The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Agent’s resignation hereunder, the provisions of this Article and Section 10.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent.

Each Lender acknowledges that it has, independently and without reliance upon either Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon either Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Notwithstanding anything herein to the contrary, the Sole Lead Arranger and Sole Bookrunner, the Syndication Agent and Co-Arranger, and the Co-Documentation Agents named on the cover page of this Agreement shall not have any duties or liabilities under this Agreement, except in their capacity, if any, as Lenders.

(vi) if to a Lender, to it at its address (or telecopy number) set forth in its Administrative Questionnaire.

(b) Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communications pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices pursuant to Article II unless otherwise agreed by the Administrative Agent and the applicable Lender. Either Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications. Without limiting the foregoing, the Borrower may furnish to the Agents and the Lenders the financial statements required to be furnished by it pursuant to Section 6.01(a) or 6.01(b) by electronic communications pursuant to procedures approved by the Administrative Agent.

(c) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto (or, in the case of any such change by a Lender, by notice to the Borrower and the Administrative Agent). All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt.

(a) No Deemed Waivers; Remedies Cumulative. No failure or delay by either Agent, any Issuing Lender or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Agents, the Issuing Lenders and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Obligor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such

waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether either Agent, any Lender or any Issuing Lender may have had notice or knowledge of such Default at the time.

(b) Amendments to this Agreement. Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall:

(i) increase any Commitment of any Lender without the written consent of such Lender;

(ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon (except in connection with the waiver of the applicability of any post-default increase in interest rates), or reduce any fees payable hereunder, without the written consent of each Lender directly affected thereby;

(iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration or reduction of any Commitment, without the written consent of each Lender directly affected thereby;

(iv) change Section 2.16(c) or 2.16(d) without the consent of each Lender directly affected thereby;

(v) change any of the provisions of this Section or the percentage in the definition of the term “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender of each adversely affected Class;

(vi) (except as provided in paragraph (d) of this Section) release all or substantially all of the Subsidiary Guarantors from their guarantee obligations under Article III, or change the definition of “Security Release Conditions”, without the written consent of each Lender; or

(vii) change the allocation of any prepayment to any Class of Loans disproportionately when compared to all other Classes entitled to such prepayment, without the written consent of the Required Lenders of each adversely affected Class.

and provided further that (x) no such agreement shall amend, modify or otherwise affect the rights or duties of either Agent or any Issuing Lender hereunder without the prior written consent

of such Agent or such Issuing Lender, as the case may be, (y) any modification or supplement of Article III shall require the consent of each Subsidiary Guarantor (it being agreed by each Subsidiary Guarantor that, except as provided in this clause (y) the consent of the Subsidiary Guarantors shall not be required for any other amendment, modification or waiver hereunder or the other Loan Documents and the Subsidiary Guarantors hereby confirm and ratify each amendment, modification and waiver approved by the Borrower) and (z) notwithstanding anything herein to the contrary, to the extent specified in Section 2.01(d), this Agreement may be amended to establish Incremental Term Loan Commitments of any Series pursuant to an Incremental Term Loan Amendment executed between the Borrower, the relevant Lenders of such Series, the Administrative Agent and the Collateral Agent, and any such Incremental Term Loan Amendment shall not require the consent of any other party to this Agreement.

(c) Amendments to the Security Documents. Except as otherwise provided in this Section, the Administrative Agent and/or the Collateral Agent, as applicable, may, with the prior consent of the Required Lenders (but not otherwise), consent to any modification, supplement or waiver under any of the Security Documents, provided that (i) except as provided in this Section or in the Security Documents, without the prior consent of each Lender, neither Agent shall release all or substantially all of the collateral or otherwise terminate all or substantially all of the Liens under the Security Document and (ii) notwithstanding anything herein or in any other Loan Document to the contrary, upon any Disposition (including any Disposition of any Subsidiary) that is permitted hereunder or consented to by the Required Lenders or any other transaction or event resulting in any Subsidiary ceasing to be a Subsidiary of the Borrower, each Agent is hereby authorized to release, without the prior consent of any Lender and at the request of the Borrower, the Guarantee of such Subsidiary under Article III and/or any Liens on any of the property or Capital Stock of such Subsidiary under the Loan Documents or any other property which is the subject of such Disposition, as applicable. Each Agent shall take any action reasonably requested by the Borrower (at the Borrower’s sole cost and expense) to effect any such release.

(d) Security Release. Notwithstanding anything herein to the contrary, upon satisfaction of the Security Release Conditions (and without any further consent of any Lender or any Agent), the Borrower shall be entitled to a release of the Liens under the Security Documents. In order to effect such release, the Borrower shall notify the Administrative Agent of its intent to effect such release, specifying the proposed date of such release, and, if applicable, shall provide the requisite notice of prepayment under Section 2.09(a). Upon the date specified for such release, if the Security Release Conditions shall have been satisfied, the Borrower shall deliver a certificate of a Financial Officer to such effect to the Administrative Agent, whereupon the Liens under the Security Documents shall, without further action, automatically be released and each Agent will (and is hereby authorized and directed by the Lenders to) take such action, at the request and expense of the Borrower, as shall be necessary to release such Liens in accordance with the relevant Security Documents.

(a) Costs and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Agents and their respective Affiliates, including the reasonable fees,

charges and disbursements of counsel for the Agents, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by any Issuing Lender in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, (iii) all out-of-pocket expenses incurred by either Agent, any Issuing Lender or any Lender, including the reasonable fees, charges and disbursements of any counsel for either Agent, any Issuing Lender or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including in connection with any workout, restructuring or negotiations in respect thereof and (iv) and all costs, expenses, taxes, assessments and other charges incurred in connection with any filing, registration, recording or perfection of any security interest contemplated by any Security Document or any other document referred to therein.

(b) Indemnification by the Borrower. The Borrower shall indemnify each Agent, each Issuing Lender and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”), against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by any Issuing Lender to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related, directly or indirectly, to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee.

(c) Reimbursement by Lenders. To the extent that the Borrower fails to pay any amount required to be paid by it to an Agent or an Issuing Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to such Agent or such Issuing Lender, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent or such Issuing Lender in its capacity as such.

(d) Waiver of Consequential Damages, Etc. To the extent permitted by applicable law, no Obligor shall assert, and each Obligor hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) Payments. All amounts due under this Section shall be payable not later than 10 days after written demand therefor.

SECTION 10.04. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Lender that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Lender that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of the Agents, the Issuing Lenders and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee; and

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund; and

(C) each Issuing Lender, provided that no consent of any Issuing Lender shall be required for an assignment of all or any portion of a Term Loan.

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or Loans of the assigning Lender subject to each

such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 or, in the case of a Term Loan, $1,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Commitments or Loans;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 10.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Agents, the Issuing Lenders and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Collateral Agent, any Issuing Lender and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee

referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i) Any Lender may, without the consent of the Borrower, the Administrative Agent or any Issuing Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Agents, the Issuing Lenders and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 10.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(d) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.15(e) as though it were a Lender.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any such pledge or assignment to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 10.05. Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made

by any such other party or on its behalf and notwithstanding that either Agent, any Issuing Lender or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15, 3.03, 10.03, 10.12 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 10.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Agents constitute the entire contract between and among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 5.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page to this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 10.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 10.08. Right of Setoff. If an Event of Default has occurred and is continuing, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of any Obligor against any of and all the obligations of any Obligor now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

(a) Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) Submission to Jurisdiction. Each Obligor hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that either Agent, any Issuing Lender or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against any Obligor or its properties in the courts of any jurisdiction.

(c) Waiver of Venue. Each Obligor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Service of Process. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 10.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 10.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

(a) Treatment of Certain Information. The Borrower acknowledges that from time to time financial advisory, investment banking and other services may be offered or provided to the Borrower or one or more of its Subsidiaries (in connection with this Agreement or otherwise) by any Lender or by one or more subsidiaries or affiliates of such Lender and the Borrower hereby authorizes each Lender to share any information delivered to such Lender by the Borrower and its Subsidiaries pursuant to this Agreement, or in connection with the decision of such Lender to enter into this Agreement, to any such subsidiary or affiliate, it being understood that any such subsidiary or affiliate receiving such information shall be bound by the provisions of paragraph (b) of this Section as if it were a Lender hereunder. Such authorization shall survive the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

(b) Confidentiality. Each of the Agents, the Issuing Lenders and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent requested by any regulatory authority, (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party to this Agreement, (v) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this paragraph, (i) to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (vii) to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section), (viii) with the consent of the Borrower or (ix) to the extent such Information (A) becomes publicly available other than as a result of a breach of this paragraph or (B) becomes available to either Agent, any Issuing Lender or any Lender on a nonconfidential basis from a source other than an Obligor. For the purposes of this paragraph, “Information” means all information received from any Obligor relating to any Obligor or its business, other than any such information that is available to either Agent, any Issuing Lender or any Lender on a nonconfidential basis prior to disclosure by an Obligor; provided that, in the case of information received from an Obligor after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 10.13. USA PATRIOT Act. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), such Lender may be required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with said Act.

(i) To the best of such Grantor’s knowledge, the rights of such Grantor in or to the Intellectual Property Collateral do not conflict with, misappropriate or infringe upon the intellectual property rights of any third party except for any such conflicts, misappropriations or infringements that,

individually or in the aggregate, would not be reasonably be expected to have a Material Adverse Effect, and no written claim has been asserted that the use of such Intellectual Property Collateral does or may infringe upon the intellectual property rights of any third party except to the extent such claims, individually or in the aggregate, would not be reasonably be expected to have a Material Adverse Effect.

(ii) Such Grantor is the exclusive owner or non-exclusive licensee of the entire and unencumbered right, title and interest in and to the Intellectual Property Collateral and is entitled to use all such Intellectual Property Collateral, subject only to the license terms of the Licenses and applicable Governmental Rules.

(iii) The Intellectual Property Collateral set forth on Schedule V hereto includes all of the patents, patent registrations, patent applications, trademark registrations and applications, copyright registrations and applications and Licenses owned by such Grantor.

(iv) To the best of such Grantor’s knowledge, the Intellectual Property Collateral material to its business is subsisting, has not been adjudged invalid or unenforceable in whole or part and is valid and enforceable. Such Grantor is not aware of any uses of any material item of Intellectual Property Collateral that would reasonably be expected to lead to such item becoming invalid or unenforceable.

(v) Such Grantor has made or performed all filings, recordings and other acts and has paid all required fees and taxes to maintain and protect its interest in each and every item of Intellectual Property Collateral in full force and effect, and to protect and maintain its interest therein including, without limitation, recordations of any of its interests in the Patents and Trademarks with the U.S. Patent and Trademark Office, except with respect to any items of Intellectual Property Collateral which such Grantor, in the reasonable exercise of its business judgment, deems not be material to the ongoing business of such Grantor.

To the best of such Grantor’s knowledge, no Person is engaging in any activity that infringes upon or misappropriates the Intellectual Property Collateral or upon the rights of such

Grantor therein except to the extent such infringement or misappropriation, individually or in the aggregate, would not be reasonably be expected to have a Material Adverse Effect. Except as set forth on Schedule V hereto, such Grantor has not granted any license, release, covenant not to sue, non-assertion assurance, or other right to any Person with respect to any material part of the Intellectual Property Collateral.

SECTION 9. Further Assurances. (a) Each Grantor agrees that from time to time, at the expense of such Grantor, such Grantor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action, that may be necessary or reasonably desirable, or that the Collateral Agent may request, in order to perfect and protect any pledge, assignment or security interest granted or purported to be granted by such Grantor hereunder or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral of such Grantor. Without limiting the generality of the foregoing, each Grantor will promptly with respect to Collateral of such Grantor: (i) at the reasonable request of the Collateral Agent, mark conspicuously each chattel paper included in Receivables, each Assigned Agreement and each of its records pertaining to such Collateral with a legend, in form and substance reasonably satisfactory to the Collateral Agent, indicating that such chattel paper, Assigned Agreement or Collateral is subject to the security interest granted hereby; provided that no such legend shall be required if such Collateral is delivered to the Collateral Agent pursuant to clause (ii) below; (ii) if any such Collateral shall be evidenced by a promissory note or other instrument or chattel paper, deliver and pledge to the Collateral Agent hereunder such note or instrument or chattel paper duly indorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance reasonably satisfactory to the Collateral Agent; (iii) execute or authenticate and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or reasonably desirable, or as the Collateral Agent may reasonably request, in order to perfect and preserve the security interest granted or purported to be granted by such Grantor hereunder; (iv) deliver and pledge to the Collateral Agent for benefit of the Secured Parties certificates representing Security Collateral that constitutes certificated

securities, accompanied by undated stock or bond powers executed in blank; and (v) deliver to the Collateral Agent evidence that all other action that the Collateral Agent may deem reasonably necessary or reasonably desirable in order to perfect and protect the security interest created by such Grantor under this Agreement has been taken.

(b) Each Grantor hereby authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, relating to all or any part of the Collateral of such Grantor without the signature of such Grantor where permitted by law. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law.

(c) Each Grantor will furnish to the Collateral Agent from time to time statements and schedules further identifying and describing the Collateral of such Grantor and such other reports in connection with such Collateral as the Collateral Agent may reasonably request, all in reasonable detail.

SECTION 10. As to Equipment and Inventory. (a) Each Grantor will keep the Equipment and Inventory of such Grantor (other than Inventory sold in the ordinary course of business, Equipment and Inventory constituting mobile goods or Equipment and Inventory in transit in the ordinary course of such Grantor’s business or Equipment and Inventory disposed of as permitted under the Credit Agreement) at the places therefor specified in Section 8(a) or, upon 30 days’ prior written notice to the Collateral Agent, at such other places in a jurisdiction where all action required by Section 9 shall have been taken with respect to such Equipment and Inventory (and, upon the taking of such action in such jurisdiction, Schedule III hereto shall be automatically amended to include such other places).

(b) Each Grantor will cause the Equipment of such Grantor (other than any Equipment not material to the business of such Grantor) to be maintained and preserved in the same condition, repair and working order as when new, ordinary wear and tear excepted, and will forthwith, or in the case of any loss or damage to any of such Equipment as soon as practicable after the occurrence thereof, make or cause to be made all repairs, replacements and other improvements in connection therewith that are necessary or reasonably desirable to such end except to the extent such Grantor deems such Equipment not to be necessary to the ongoing business of such Grantor.

(c) Each Grantor will pay promptly when due all property and other taxes, assessments and governmental charges or levies imposed upon, and all claims (including, without limitation, claims for labor, materials and supplies) against, the Equipment and Inventory of such Grantor, except to the extent payment thereof is not required by Section 6.04 of the Credit Agreement. In producing its Inventory, each Grantor will comply with all requirements of applicable law, including, without limitation, the Fair Labor Standards Act, except where any such noncompliance would not be reasonably likely to result in a Material Adverse Effect.

SECTION 11. Insurance. (a) Each Grantor will, at its own expense, maintain insurance with respect to the Equipment and Inventory of such Grantor in such amounts, against such risks, in such form and with such insurers, as is customary with companies of a similar size

and line of business. Each policy of each Grantor for general liability insurance shall provide for the Collateral Agent as additional insured. Each policy of each Grantor for property damage insurance shall (i) name such Grantor and the Collateral Agent as insured parties thereunder (without any representation or warranty by or obligation upon the Collateral Agent) as their interests may appear, (ii) name the Collateral Agent as a loss payee thereunder (provided that losses thereunder shall be payable to the Collateral Agent only if at the time of payment thereof the insurer has been notified in writing by such Grantor or the Collateral Agent that an Event of Default shall have occurred and be continuing), (iii) provide that there shall be no recourse against the Collateral Agent for payment of premiums or other amounts with respect thereto and (iv) provide that at least 10 days’ prior written notice of cancellation shall be given to the Collateral Agent by the insurer. Each Grantor will, if so requested by the Collateral Agent, deliver to the Collateral Agent original or duplicate policies or certificates of such insurance provided by the insurance companies and, as often as the Collateral Agent may reasonably request, a report of a reputable insurance broker with respect to such insurance. Further, each Grantor will, at the request of the Collateral Agent, duly execute and deliver instruments of assignment of such insurance policies to comply with the requirements of Section 9 and use reasonable efforts to cause the insurers to acknowledge notice of such assignment.

(b) Reimbursement under any liability insurance maintained by any Grantor pursuant to this Section 11 may be paid directly to the Person who shall have incurred liability covered by such insurance. In case of any loss involving damage to Equipment or Inventory when subsection (c) of this Section 11 is not applicable, the applicable Grantor will make or cause to be made the necessary repairs to or replacements of such Equipment or Inventory, and any proceeds of insurance properly received by or released to such Grantor shall be used by such Grantor, except as otherwise required hereunder or permitted by the Credit Agreement, to pay or as reimbursement for the costs of such repairs or replacements.

(c) So long as no Event of Default shall have occurred and be continuing, all insurance payments received by the Collateral Agent in connection with any loss, damage or destruction of any Inventory or Equipment will be released by the Collateral Agent to the applicable Grantor for the repair, replacement or restoration thereof, subject to such terms and conditions with respect to the release thereof as the Collateral Agent may reasonably require. Upon the occurrence and during the continuance of any Event of Default, all insurance payments in respect of such Equipment or Inventory shall be paid to the Collateral Agent and shall, in the Collateral Agent’s sole discretion, (i) be released to the applicable Grantor to be applied as set forth in the first sentence of this subsection (c) or (ii) be held as additional Collateral hereunder or applied as specified in Section 21(b).

SECTION 12. Place of Perfection; Records; Collection of Receivables. (a) Each Grantor will not change its name, type of legal entity, federal tax identification number, organizational identification number or location from those set forth in Section 8(a) and Section 8(b) without first giving at least 15 days’ advance written notice to the Collateral Agent and taking all action required by the Collateral Agent for the purpose of perfecting or protecting the liens granted by this Agreement. Each Grantor will also keep the originals of the Assigned Agreements and Related Contracts to which such Grantor is a party and all originals of all chattel paper that evidence Receivables of such Grantor, at the location therefor specified in Section 8(a) or, upon 15 days’ prior written notice to the Collateral Agent, at such other location in a

jurisdiction where all actions required by Section 9 shall have been taken with respect to the Collateral of such Grantor (and, upon the taking of such action in such jurisdiction, Schedule IV hereto shall be automatically amended to include such other location). Each Grantor will hold and preserve its records relating to the Collateral, the Assigned Agreements, the Related Contracts and chattel paper and will permit representatives of the Collateral Agent at any time during normal business hours and with reasonable prior notice to inspect and make abstracts from such records and other documents.

(b) Except as otherwise provided in this subsection (b), each Grantor will continue to collect, at its own expense, all amounts due or to become due to such Grantor under the Receivables and the Related Contracts. In connection with such collections, such Grantor may take (and, at the Collateral Agent’s direction upon the occurrence and during the continuance of an Event of Default, will take) such action as such Grantor or the Collateral Agent may deem reasonably necessary or advisable to enforce collection of the Receivables and the Related Contracts; provided that the Collateral Agent shall have the right at any time, upon the occurrence and during the continuance of an Event of Default and upon written notice to such Grantor of its intention to do so, to notify the obligors (each individually, a “Contract Obligor” and collectively, the “Contract Obligors”) under any Receivables or Related Contracts of the assignment of such Receivables or Related Contracts to the Collateral Agent and to direct such Contract Obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the Collateral Agent and, upon such notification and at the expense of such Grantor, to enforce collection of any such Receivables or Related Contracts, and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done. Upon the occurrence and during the continuance of an Event of Default, (i) all amounts and proceeds (including instruments) received by such Grantor in respect of the Receivables and the Related Contracts of such Grantor shall be received in trust for the benefit of the Collateral Agent hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Agent in the same form as so received (with any necessary endorsement) to be held as cash collateral and shall be applied as provided in Section 21(b) and (ii) such Grantor will not adjust, settle or compromise the amount or payment of any Receivable, release wholly or partly any Contract Obligor thereof, or allow any credit or discount thereon. No Grantor will permit or consent to the subordination of its right to payment under any of the Receivables or the Related Contracts to any other indebtedness or obligations of the Contract Obligor thereof.

SECTION 13. As to Intellectual Property Collateral. (a) With respect to each item of its Intellectual Property Collateral (except with respect to any items of Intellectual Property Collateral which such Grantor, in its reasonable business judgment, deems not to be material to the ongoing business of such Grantor), each Grantor agrees to take, at its expense, all necessary steps, including, without limitation, in the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authority, to (i) maintain the validity and enforceability of each such item of Intellectual Property Collateral and maintain each such item of Intellectual Property Collateral in full force and effect, and (ii) pursue the registration and maintenance of each patent, trademark, or copyright registration or application, now or hereafter included in the Intellectual Property Collateral of such Grantor, including, without limitation, the payment of required fees and taxes, the filing of responses to office actions issued by the U.S. Patent and Trademark Office, the U.S. Copyright Office or other governmental authorities, the

filing of applications for renewal or extension, the filing of affidavits under Sections 8 and 15 of the U.S. Trademark Act, the filing of divisional, continuation, continuation-in-part, reissue and renewal applications or extensions, the payment of maintenance fees and the participation in interference, reexamination, opposition, cancellation, infringement and misappropriation proceedings. No Grantor shall, without the written consent of the Collateral Agent, discontinue use of or otherwise abandon any Intellectual Property Collateral, or abandon any right to file an application for letters patent, trademark, or copyright, unless such Grantor shall have previously determined that such use or the pursuit or maintenance of such Intellectual Property Collateral is no longer desirable in the conduct of such Grantor’s business and that the loss thereof would not be reasonably likely to have a Material Adverse Effect, in which case, such Grantor will give prompt notice of any such abandonment to the Collateral Agent.

(b) Except as provided in this Section regarding the discontinuation of use or abandonment of any Intellectual Property Collateral, each Grantor agrees promptly to notify the Collateral Agent if such Grantor learns (i) that any item of the Intellectual Property Collateral may have become abandoned, placed in the public domain, invalid or unenforceable, or of any adverse determination or development regarding such Grantor’s ownership of any of the Intellectual Property Collateral or its right to register the same or to keep and maintain and enforce the same, or (ii) of any adverse determination or the institution of any proceeding (including, without limitation, the institution of any proceeding in the U.S. Patent and Trademark Office or any court) regarding any item of the Intellectual Property Collateral.

(c) In the event that any Grantor becomes aware that any item of the Intellectual Property Collateral material to the business of such Grantor is being infringed or misappropriated by a third party, such Grantor shall promptly notify the Collateral Agent and shall take such actions, at its expense, as such Grantor or the Collateral Agent deems reasonable and appropriate under the circumstances to protect such Intellectual Property Collateral, including, without limitation, suing for infringement or misappropriation and for an injunction against such infringement or misappropriation.

(d) Each Grantor shall use proper statutory notice in connection with its use of each item of its Intellectual Property Collateral. Except with respect of any item of Intellectual Property Collateral, which such Grantor, in the reasonable exercise of its business judgment, deems not to be material to the ongoing business of such Grantor, no Grantor shall do or permit any act or knowingly omit to do any act whereby any of its Intellectual Property Collateral may lapse or become invalid or unenforceable or placed in the public domain.

(e) Except with respect of any item of Intellectual Property Collateral, which such Grantor, in the reasonable exercise of its business judgment, deems not to be material to the ongoing business of such Grantor, each Grantor shall take all steps which it or the Collateral Agent deems reasonable and appropriate under the circumstances to preserve and protect each item of its Intellectual Property Collateral, including, without limitation, maintaining the quality of any and all products or services used or provided in connection with any of the Trademarks, consistent with the quality of the products and services as of the date hereof, and taking all steps necessary to ensure that all licensed users of any of the Trademarks use such consistent standards of quality.

(f) With respect to its Intellectual Property Collateral, each Grantor agrees to execute an agreement, in substantially the form set forth in Exhibit C hereto (an “Intellectual Property Security Agreement”), for recording the security interest granted hereunder to the Collateral Agent in such Intellectual Property Collateral with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such Intellectual Property Collateral.

(g) Each Grantor agrees that, should it obtain an ownership interest in any item of the type set forth in Section 1(g) which is not on the date hereof a part of the Intellectual Property Collateral (the “After-Acquired Intellectual Property”), (i) the provisions of Section 1 shall automatically apply thereto, (ii) any such After-Acquired Intellectual Property and, in the case of trademarks, the goodwill of the business connected therewith or symbolized thereby, shall automatically become part of the Intellectual Property Collateral subject to the terms and conditions of this Agreement with respect thereto, (iii) such Grantor shall give prompt written notice thereof to the Collateral Agent in accordance herewith and (iv) such Grantor shall execute and deliver to the Collateral Agent an IP Security Agreement Supplement covering such After-Acquired Intellectual Property as “Additional Collateral” thereunder and as defined therein, and shall record such IP Security Agreement Supplement with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such After-Acquired Intellectual Property.

SECTION 14. Voting Rights; Dividends; Etc. (a) So long as no Event of Default shall have occurred and be continuing:

(i) Each Grantor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Security Collateral of such Grantor or any part thereof for any purpose; provided that such Grantor will not exercise or refrain from exercising any such right if such action would have a material adverse effect on the value of the Security Collateral or any part thereof.

(ii) Each Grantor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in respect of the Security Collateral of such Grantor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Loan Documents; provided that any and all dividends, interest and other distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Security Collateral received after the date of the initial extension of credit under the Credit Agreement, shall be, and shall be forthwith delivered to the Collateral Agent to hold as, Security Collateral and shall, if received by such Grantor, be received in trust for the benefit of the Collateral Agent, be segregated from the other property or funds of such Grantor and be forthwith delivered to the Collateral Agent as Security Collateral in the same form as so received (with any necessary endorsement).

(iii) The Collateral Agent will execute and deliver (or cause to be executed and delivered) to each Grantor all such proxies and other instruments as such Grantor may reasonably request for the purpose of enabling such Grantor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the

dividends or interest payments that it is authorized to receive and retain pursuant to paragraph (ii) above.

(i) All rights of each Grantor (x) to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 14(a)(i) shall, upon notice to such Grantor by the Collateral Agent, cease and (y) to receive the dividends, interest and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 14(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions, subject to obtaining the approval of the applicable HMO Regulator or Insurance Regulator prior to the exercise by the Collateral Agent of its foreclosure, voting, assignment or other rights with respect to any Pledged Shares issued by any HMO Subsidiary or Insurance Subsidiary where such approval is required for the Collateral Agent to exercise such rights under the applicable Governmental Rules.

(ii) All dividends, interest and other distributions that are received by any Grantor contrary to the provisions of paragraph (i) of this Section 14(b) shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Collateral Agent as Security Collateral in the same form as so received (with any necessary endorsement).

SECTION 15. As to the Assigned Agreements. (a) Each Grantor will at its expense:

(i) perform and observe in all material respects all terms and provisions of the Assigned Agreements to be performed or observed by it, maintain the Assigned Agreements to which it is a party in full force and effect to the extent deemed prudent by such Grantor, enforce the Assigned Agreements to which it is a party in accordance with the terms thereof, and take all such action to such end as may be reasonably requested from time to time by the Collateral Agent upon the occurrence and continuance of an Event of Default; and

(ii) (A) furnish to the Collateral Agent copies of the Assigned Agreements as then in effect and such information and reports regarding the Assigned Agreements and such other Collateral of such Grantor as the Collateral Agent may reasonably request and (B) upon reasonable request of the Collateral Agent upon the occurrence and continuation of an Event of Default make to each other party to any Assigned Agreement to which it is a party such demands and requests for information and reports or for action as such Grantor is entitled to make thereunder.

(b) Each Grantor hereby consents on its behalf and on behalf of its Subsidiaries to the assignment and pledge, for security purposes, to the Collateral Agent for benefit of the Secured Parties of each Assigned Agreement to which it is a party.

SECTION 16. Payments Under the Assigned Agreements. All moneys received or collected pursuant to any Assigned Agreement shall be (i) released to the applicable Grantor so long as no Event of Default shall have occurred and be continuing or (ii) if any Event of Default shall have occurred and be continuing, applied as provided in Section 21(b), subject to obtaining the approval of the applicable HMO Regulator or Insurance Regulator prior to the exercise by the Collateral Agent of its foreclosure, voting, assignment or other rights with respect to any Assigned Agreements to which any HMO Subsidiary or Insurance Subsidiary is a party where such approval is required for the Collateral Agent to exercise such rights under the applicable Governmental Rules.

SECTION 17. Transfers and Other Liens; Additional Shares. (a) Each Grantor agrees that it will not (i) sell, assign or otherwise dispose of, or grant any option with respect to, any of the Collateral, other than sales, assignments and other dispositions of Collateral, and options relating to Collateral, permitted under the terms of the Credit Agreement, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral of such Grantor except for the pledge, assignment and security interest created under this Agreement or permitted under the terms of the Credit Agreement.

SECTION 18. Collateral Agent Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints the Collateral Agent such Grantor’s attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time, upon the occurrence and during the continuance of an Event of Default, in the Collateral Agent’s discretion, to take any action and to execute any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation:

(a) to obtain and adjust insurance required to be paid to the Collateral Agent pursuant to Section 11,

SECTION 19. Collateral Agent May Perform. If any Grantor fails to perform any agreement contained herein, the Collateral Agent may, as the Collateral Agent deems necessary to protect the security interest granted hereunder in the Collateral or to protect the value thereof, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by such Grantor under Section 22(b).

SECTION 20. The Collateral Agent’s Duties. (a) The powers conferred on the Collateral Agent hereunder are solely to protect the Secured Parties’ interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property.

(b) Anything contained herein to the contrary notwithstanding, the Collateral Agent may from time to time, when the Collateral Agent deems it to be necessary, appoint one or more subagents (each a “Subagent”) for the Collateral Agent hereunder with respect to all or any part of the Collateral. In the event that the Collateral Agent so appoints any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Grantor hereunder shall be deemed for purposes of this Agreement to have been made to such Subagent, in addition to the Collateral Agent, for the ratable benefit of the Secured Parties, as security for the Secured Obligations of such Grantor, (ii) such Subagent shall automatically be vested, in addition to the Collateral Agent, with all rights, powers, privileges, interests and remedies of the Collateral Agent hereunder with respect to such Collateral, and (iii) the term “Collateral Agent,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Collateral Agent with respect to such Collateral, shall include such Subagent; provided that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Collateral Agent.

SECTION 21. Remedies. If any Event of Default shall have occurred and be continuing:

(a) Subject to obtaining the approval of the applicable HMO Regulator or Insurance Regulator prior to the exercise by the Collateral Agent of its foreclosure, voting, assignment or other rights with respect to any of the Pledged Shares or the Pledged Debt issued by any HMO Subsidiary or Insurance Subsidiary or any Assigned Agreement to which any HMO Subsidiary or Insurance Subsidiary is a party where such approval is required under the applicable Governmental Rules, the Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the N.Y. Uniform Commercial Code (whether or not the N.Y. Uniform

Commercial Code applies to the affected Collateral) and also may: (i) require each Grantor to, and each Grantor hereby agrees that it will at its expense and upon request of the Collateral Agent forthwith, assemble all or part of the Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place and time to be designated by the Collateral Agent that is reasonably convenient to both parties; (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable; (iii) occupy any premises owned or leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; and (iv) exercise any and all rights and remedies of any of the Grantors under or in connection with the Assigned Agreements, the Receivables and the Related Contracts or otherwise in respect of the Collateral, including, without limitation, any and all rights of such Grantor to demand or otherwise require payment of any amount under, or performance of any provision of, the Assigned Agreements, the Receivables and the Related Contracts. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) Any cash held by or on behalf of the Collateral Agent and all cash proceeds received by or on behalf of the Collateral Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Collateral Agent, be held by the Collateral Agent as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Collateral Agent pursuant to Section 22) in whole or in part by the Collateral Agent for the ratable benefit of the Secured Parties against, all or any part of the Secured Obligations, in the following manner:

(i) first, to the Agents for any amounts owing to the Agents pursuant to Section 10.03(a) of the Credit Agreement or otherwise under the Loan Documents, ratably in accordance with such respective amounts then owing to the Agents; and

(ii) second, to the payment in full of the other Secured Obligations, in each case equally and ratably in accordance with their respective amounts thereof then due and owing or as the Secured Parties holding the same may otherwise agree.

With respect to our opinions in paragraphs 8 through 11 below, with your further permission, we have assumed, without investigation, that the applicable Obligor has rights, or the power to transfer to a secured party rights, in the Collateral in which it purports to create a security interest under the Transaction Documents to which it is a party within the meaning and for the purposes of Section 9-203(b)(2) of the NYUCC, and our opinions expressed below are expressed only to the extent such Obligor has such rights.

interest created by the Security Agreement in the Collateral violates the rights of another secured party.

With regard to our opinion in paragraph 3 below as to PacifiCare Health Plan Administrators, Inc., an Indiana corporation (“PHPA”), and American Medical Security Group, Inc., a Wisconsin corporation (“AMSG”) and the other Obligors, we have assumed that such corporations are duly incorporated, validly existing and are in good standing in the jurisdiction of organization and that each of the Transaction Documents to which each Obligor is a party have been duly authorized by all necessary corporate action on the part of each Obligor, as applicable.

With regard to our opinion in paragraph 11 below, we have assumed that the original promissory notes evidencing the Initial Pledged Debt (as defined in the Security Agreement) each are instruments within the meaning of NYUCC Section 9-102(a)(47).

Our opinion in paragraph 1 below as to the good standing of the Company as a domestic corporation in the State of Delaware and the Company’s qualification to do business as a foreign corporation in the State of California is based solely upon our review of the applicable Good Standing Certificates. We have made no further investigation.

With regard to our opinion paragraph 5 and 6 below concerning defaults under or any material breaches of any agreement identified on Schedule II hereto, we have relied solely upon (i) inquiries of officers of the Company (ii) a list supplied to us by the Company of material agreements to which the Company or AMSG is a party, or by which the Company or AMSG is bound, a copy of which is attached hereto as Schedule II (the “Material Agreements”), and (iii) an examination of the Material Agreements in the form provided to us by the Company.

We have made no further investigation.

With regard to our opinion in paragraph 13 below, we have relied upon that certain SEC Order dated November 22, 2004 (Investment Company Act Release No. 26679; 812-12953) pursuant to Sections 3(b)(2) and 45(a) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), declaring that certain of the Company’s Subsidiaries are primarily

engaged in a business other than that of investing, reinvesting, owning, holding or trading in securities (the “Order”) We also have relied upon a certificate of an officer of the Company regarding (i) the value of investment securities owned by Subsidiary Guarantors that are not covered by the Order and (ii) such other factual matters as we have deemed advisable. We have conducted no further investigation. The terms “value” and “investment securities” have the meanings ascribed to them in Section 2(a)(41) and Section 3(a)(2), respectively, of the Investment Company Act of 1940, as amended.

We have assumed the due filing, at the time the Loans are initially made and this opinion letter is issued, of (i) each of the Company Financing Statement, the SeniorCo Financing Statement, the Behavioral Health Financing Statement and the PacifiCare Southwest Financing Statement with the UCC Section of the Secretary of State of the State of Delaware and (ii) each of the eHoldings Financing Statement, the Rx Solutions Financing Statement and the SecureHorizons Financing Statement with the UCC Division of the Secretary of State of the State of California.

On the basis of the foregoing, in reliance thereon, and with the qualifications set forth herein, we are of the opinion that:

1. The Company is duly incorporated, validly existing and in good standing under the laws of the State of Delaware, and has the corporate power to enter into and perform its obligations under the Transaction Documents and to own, lease and license its properties and to transact its business as currently conducted. The Company is qualified as a foreign corporation to do business and is in good standing in the State of California.

2. The execution, delivery and performance by the Company of each of the Transaction Documents to which the Company is a party and the issuance by the Company of the Notes and each other promissory note of the Company in accordance with Section 2.08(g) of the Agreement and in the form of Exhibit F-1, F-2 or F-3 as required by Section 2.08(g) of the Agreement have been duly authorized by all necessary corporate action on the part of the Company and each of the Transaction Documents have been duly executed and delivered by the Company.

3. As to each Obligor, each of the Transaction Documents to which such Obligor is a party constitutes, and each other promissory note of the Company when executed and delivered by the Company for value in accordance with Section 2.08(g) of the Agreement and in the form of Exhibit F-1, F-2 or F-3 as required by Section 2.08(g) of the Agreement will constitute, a valid and binding obligation of such Obligor, enforceable against such Obligor in accordance with its terms.

4. No consents, approvals, authorizations, registrations, declarations or filings are required to be obtained or made by the Company from or with any U.S. federal or California governmental authority or pursuant to the General Corporation Law of the State of Delaware in order for the Company to execute, deliver and be obligated to perform its obligations under the Transaction Documents, except for such as have been obtained or made and are in full force and effect.

5. The execution and delivery by the Company of each of the Transaction Documents, the issuance by the Company of the Notes and each other promissory note of the Company in accordance with Section 2.08(g) of the Agreement and in the form of Exhibit F-1, F-2 or F-3 as required by Section 2.08(g) of the Agreement and the performance as of the date of this opinion letter (the “Closing Date”) by the Company of the Transaction Documents does not constitute a default under or a material breach of, or result in the imposition of any contractual pledge, security interest or other encumbrance in or on any of the property of the Company pursuant to, or require any consent or approval under any Material Agreement to which it is a party, except for such as have been obtained or made and are in full force and effect and does not violate (a) any provision of the Company Organizational Documents or (b) any provision of the Delaware General Corporation Law, or any provision of any U.S. federal or California law, rule or regulation which in our experience is typically applicable to commercial transactions of the nature contemplated by the Transaction Documents.

6. The execution and delivery by AMSG of each of the Transaction Documents to which it is a party and the performance as of the Closing Date by AMSG of the Transaction Documents does not constitute a default under or a material breach of, or result in the imposition of any contractual pledge, security interest or other encumbrance in or on any of the property of the Company pursuant to, or require any consent or approval under any Material Agreement to which it is a party, except for such as have been obtained or made and are in full force and effect.

9. Each of the Company Financing Statement, the SeniorCo Financing Statement, the Behavioral Health Financing Statement and the PacifiCare Southwest Financing Statement is in form sufficient for filing with the filing office of the Secretary of State of the State of Delaware, and each of the eHoldings Financing Statement, the Rx Solutions Financing Statement and the SecureHorizons Financing Statement is in form sufficient for filing with the filing office of the Secretary of State of the State of California. Upon the due filing of such Financing Statements with the UCC Section of the Secretary of State of the State of Delaware or the UCC Division of the Secretary of State of the State of California, as applicable, the security interest of the Collateral Agent for the Secured Parties in the personal property Collateral identified and described in the Security Agreement and such Financing Statements will be perfected to the extent that a security interest in such Collateral can be perfected by the filing of a UCC-1 financing statement in such filing office.

10. The security interest granted by the Obligors party to the Security Agreement has attached to the Obligors’ rights in the original certificates evidencing equity securities comprising Initial Pledged Shares, as defined in the Security Agreement (the “Pledged Certificates”). Upon the Collateral Agent’s having “control” of the Pledged Certificates, within the meaning of NYUCC Section 8-106, by taking delivery of the Pledged Certificates, within the meaning of NYUCC Section 8-301, and maintaining continuous physical possession thereof within the State of New York, the security interest granted therein to the Collateral Agent will constitute a valid and perfected security interest in the Initial Pledged Shares under NYUCC Section 9-313(a), entitled to the priority provided by NYUCC Section 9-328(b)(1).

11. The security interest granted by the Obligors that are parties to the Security Agreement has attached to the Obligors’ rights in the original promissory notes evidencing the Initial Pledged Debt, as defined in the Security Agreement (the “Pledged Notes”). Upon the Collateral Agent’s taking and maintaining continuous physical possession of the Pledged Notes within the State of New York, the security interests granted by the Obligors therein to the Collateral Agent will constitute a valid and perfected security interest under NYUCC Section 9-313(a), entitled to the priority provided by NYUCC Section 9-330(d).

12. To our knowledge, there are is no action, proceeding or investigation pending or overtly threatened against Company or AMSG before any court or administrative agency that questions the validity of the Transaction Documents or that would reasonably be expected to have a Material Adverse Effect on the Company except for those matters disclosed on Schedule 4.06(a) of the Agreement.

13. (a) Neither the Company nor any Subsidiary Guarantor is an “investment company”, as such term is defined in the Investment Company Act, and (b) neither the Company nor any Subsidiary Guarantor is a “holding company” within the meaning of the Public Utility Holding Company Act of 1935.

(b) We express no opinion as to the enforceability of “choice of forum” or “submission to jurisdiction” provisions contained in any of the Transaction Documents.

Guarantors), (b) the binding effect upon, and enforceability against, such other parties to the Transaction Documents and all other agreements, instruments and documents reviewed or examined by us (other than with respect to the PHS Subsidiary Guarantors), (c) the authenticity and completeness of all agreements, instruments and documents submitted to us as originals, (d) the conformity to authentic original agreements, instruments and documents of all agreements, instruments and documents submitted to us as copies, (e) the due incorporation or formation, valid existence, good standing and the corporate or similar power to enter into, and perform in accordance with their terms the Transaction Documents of all parties thereto (other than with respect to the PHS Subsidiary Guarantors), (f) the accuracy, completeness and authenticity of certificates of public officials, (g) the legal capacity of all individuals executing and delivering documents to so execute and deliver and (h) there are no extrinsic agreements or understandings among the parties to the Transaction Documents that would modify or interpret the terms of the Transaction Documents or the respective rights or obligations of the parties thereunder.

We also have obtained such certificates from public officials and officers of the PHS Subsidiary Guarantors and done such other things as we have determined to be necessary to render this opinion. As to questions of fact material to our opinions, we have, without independent investigation, relied upon all of the foregoing.

Our opinion in paragraph 1 below as to the good standing of SeniorCo, PBHI and PacifiCare Southwest as a domestic corporation in the State of Delaware and SeniorCo and PBHI as a foreign corporation in the State of California and PacifiCare Southwest as a foreign corporation in the States of Oklahoma and Texas is based solely upon our review of the applicable Good Standing Certificates. Our opinion in paragraph 1 below as to the good standing of each of eHoldings, RxSolutions and SHUSA as a domestic corporation in the State of California is based solely upon our review of the applicable Good Standing Certificates. We have made no further investigation.

We are members of the bar of the State of California and we do not represent ourselves to be expert in the laws of any other state. This opinion is limited to matters governed by the Delaware General Corporation Law (the “DGCL”), the laws of the State of California and any federal laws applicable solely to the health care operations, if any, of the PHS Subsidiary Guarantors (“Applicable Federal Health Care Laws”). We express no opinion with respect to the laws of any state other than the State of California and the State of Delaware.

1. Each of SeniorCo, PBHI and PacifiCare Southwest is duly incorporated, validly existing and in good standing under the laws of the State of Delaware. Each of SeniorCo and PBHI is qualified as a foreign corporation to do business and is in good standing in the State of California. PBHI is also qualified as a foreign corporation to do business and is in good standing in the State of Texas. PBHI is also qualified as a foreign corporation to do business in and is certified by the Secretary of State of the State of Colorado to be in good standing in the State of Colorado. PacifiCare Southwest is qualified as a foreign corporation to do business and is in

good standing in the States of Oklahoma and Texas. Each of eHoldings, RxSolutions and SHUSA is duly incorporated, validly existing and in good standing under the laws of the State of California.

such consent or approval, would not have a Material Adverse Effect and (b) except for the Liens created pursuant to the Security Documents, will not result in the imposition of any Lien on any assets of SeniorCo.

8. The execution and delivery by PacifiCare Southwest of each of the Transaction Documents to which it is a party and the performance as of the Effective Date by PacifiCare Southwest of the Transaction Documents to which it is a party (a) will not violate or contravene or be in conflict with, or result in a breach or default of, or require any consent or approval under, except for such as have been obtained or made and are in full force and effect: (i) any provision of the PacifiCare Southwest Organizational Documents; (ii) any provision of any Oklahoma or Texas law, rule or regulation applicable to the operations of PacifiCare Southwest as a third party administrator or utilization review agent in those states in respect of commercial transactions of the nature contemplated by the Transaction Documents or of the DGCL; or (iii) any material term or condition of any material written agreement, contract, undertaking, indenture or instrument to which PacifiCare Southwest is a party, except in the case of the matters referred to in clauses (ii) and (iii) where such violation, contravention, conflict, breach or default, or failure to obtain such consent or approval, would not have a Material Adverse Effect and (b) except for the Liens created pursuant to the Security Documents, will not result in the imposition of any Lien on any assets of PacifiCare Southwest.

9. Each PHS Subsidiary Guarantor has duly executed and delivered each of the Transaction Documents to which such PHS Subsidiary Guarantor is a party.

10. No authorization, consent or approval by, and no notice to, or filing or registration with, any California or federal governmental authority or body is required for the due execution, delivery, or performance by any of the PHS Subsidiary Guarantors of any of their respective obligations under the Transaction Documents to which they are a party, except for such authorization, approvals and filings as have been obtained or made.

11. To our knowledge, no action, suit or other legal proceeding, arbitration proceeding or investigation is pending by or before any court or governmental authority or in any formal arbitration, or is overtly threatened against any of the PHS Subsidiary Guarantors or any of their respective properties that seeks to enjoin the performance or questions the validity or enforceability of the Transaction Documents to which the PHS Subsidiary Guarantors are a party.

As used in this opinion letter, the phrase “to our knowledge” is intended to indicate that, during the course of our representation of the PHS Subsidiary Guarantors, no information that would give us knowledge of the inaccuracy of the statements made has come to the attention of those attorneys in this firm who have rendered legal services on behalf of the PHS Subsidiary Guarantors and that we have relied upon certificates of appropriate representatives of the PHS Subsidiary Guarantors as to the factual matters covered by such certificates. However, except to the extent otherwise set forth above, we have not undertaken any independent inquiry to

determine the accuracy of any such statement; no reference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the PHS Subsidiary Guarantors.

The foregoing opinions are also subject to the following comments and qualifications:

Our opinions set forth above are limited to the matters expressly set forth in this opinion letter, and no opinion has been implied, or may be inferred, beyond the matters expressly stated. This opinion speaks only as to law and facts in effect or existing as of the date hereof and we undertake no obligation or responsibility to update or supplement this opinion to reflect any facts or circumstances that may hereafter come to our attention or any changes in any law, which may hereafter occur.

This opinion letter is being provided by us as counsel to the PHS Subsidiary Guarantors for the benefit of the addressees of this letter and such other entities as shall become Lenders, Collateral Agents or Administrative Agent under the Credit Agreement pursuant to its terms and may not be made available or relied upon by any other Person, firm or entity without our prior written consent (provided that copies of this opinion letter may be made available to the counsel, assignees, transferees, participants and regulators of the addressees of this letter).

We have acted as special Indiana counsel to PacifiCare Health Systems, Inc., a Delaware corporation (the “Company”), in connection with that certain Credit Agreement dated as of the date hereof (the “Agreement”), among the Company, the Subsidiary Guarantors party thereto, the banks, financial institutions and other lenders party thereto (the “Lenders”), JPMorgan Chase Bank, N.A. (“JPMCB”), in its capacity as administrative agent for the benefit of the Lenders (in such capacity, the “Administrative Agent”) and JPMCB, in its capacity as collateral agent for the benefit of the Secured Parties (in such capacity, the “Collateral Agent”). All capitalized terms used but not defined herein shall have the respective meanings given to such terms in the Agreement.

This opinion is furnished to you at the request and on behalf of the Company pursuant to Section 5.01(b) of the Agreement, as special Indiana counsel, as to certain matters relating to PacifiCare Health Plan Administrators, Inc., an Indiana corporation (“PHPA”), one of the Subsidiary Guarantors.

(a) Examined, are familiar with, and have relied upon, originals or copies, certified or otherwise identified to our satisfaction, of such agreements, documents, certificates and other instruments as we have deemed necessary or appropriate to serve as the basis for the opinions set forth herein, including:

(b) Made such other investigations as in our judgment were necessary or appropriate to enable us to render the opinions expressed below.

Items (a)(i) and (ii) above are hereinafter from time to time collectively referred to as the “Transaction Documents.” Items (a)(iii) through (vi) above are hereinafter collectively referred to as the “PHPA Organizational Documents.”

In our examination of the Transaction Documents, the PHPA Organizational Documents and the PHPA Financing Statement and in rendering the opinions expressed below, we have assumed, without investigation: (a) the genuineness and authenticity of all signatures, (b) the authenticity and completeness of all agreements, documents, certificates and instruments submitted to us as originals; (c) the conformity to originals of all agreements, documents, certificates and instruments submitted to us as certified, conformed or photostatic copies; (d) the accuracy, completeness and authenticity of certificates of public officials; (e) the due organization or formation, valid existence and good standing in the jurisdiction of organization and the corporate or similar power to enter into and perform the Transaction Documents in accordance with their respective terms, of all Persons party to any Transaction Document (except that such assumption is not made as to the due incorporation and valid existence in the State of Indiana and corporate power of PHPA); (f) the due authorization, execution and delivery of all

Transaction Documents (except that such assumption is not made as to the due authorization, execution and delivery by PHPA of the Transaction Documents) in each case where the authorization, execution and delivery thereof by the parties are prerequisites to the effectiveness of such documents; (g) the legal capacity of all individuals executing and delivering documents to so execute and deliver; (h) that the Transaction Documents are valid and binding obligations, enforceable in accordance with their respective terms against all Persons party thereto (except that such assumption is not made as to PHPA with respect to the Transactions Documents); and (i) there are no extrinsic agreements or understandings among the parties to the Transactions Documents that would modify or interpret the terms of the Transaction Documents or their respective rights or obligations of the parties thereunder. We understand that the loans to be made pursuant to the Agreement will be used, in part, for the working capital requirements of PHPA.

As to factual matters material to this opinion, we have relied, with your permission and without independent investigation, upon a certificate of the President and the Chief Financial Officer of PHPA (a copy of which is attached hereto). For purposes of this opinion, we have also assumed that, following the consummation of the Agreement, the Company and PHPA will comply with all post-transaction reporting that may be required by federal, state or local law, including any reporting required under Indiana Code § 27-1-23 (Regulation of Insurance Company Holding Systems).

We express no opinion herein with respect to the priority of the security interests granted in the Security Agreement or the Intellectual Property Security Agreement.

Based upon and subject to the foregoing, and subject to the additional qualifications set forth at the end of this opinion, we are of the opinion that:

1. PHPA is duly incorporated and validly existing under the laws of the State of Indiana, and has the corporate power to enter into and perform its obligations under the Transaction Documents and to own, lease and license its properties and to transact business as a third party administrator licensed in the State of Indiana.

2. The execution, delivery and performance by PHPA of each of the Transaction Documents have been duly authorized by all requisite corporate action on the part of PHPA and do not require any further approval of its directors or shareholders.

4. Each of the Transaction Documents constitutes a valid and binding obligation of PHPA, enforceable against it in accordance with its terms, except as such enforceability may be limited by (a) bankruptcy, insolvency, reorganization, moratorium or other similar laws enacted for the relief of debtors generally, from time to time in effect, and other similar laws or court

decisions relating to or affecting the enforcement of the rights of creditors generally, and (b) the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law).

5. No consents, approvals, authorizations, registrations or filings are required to be obtained or made by PHPA under any Indiana law in order for PHPA to execute, deliver or perform its obligations under the Transaction Documents.

6. The execution and delivery by PHPA of each of the Transaction Documents and the performance as of the Effective Date by PHPA of the Transaction Documents will not violate or contravene or be in conflict with, or result in the imposition of any contractual pledge, security interest or other encumbrance in or on any of the property of PHPA pursuant to, or require any consent or approval under: (a) any provision of the Organizational Documents; (b) any provision of Indiana applicable to PHPA in commercial transactions of the nature contemplated by the Transaction Documents; or (c) any term or condition of any material written agreement, contract, undertaking, indenture or instrument to which PHPA is a party of which we are aware.

7. The PHPA Financing Statement is in form sufficient (a) for filing with the office of the Secretary of State of Indiana, and (b) to perfect the security interest of the Collateral Agent for the Secured Parties in the personal property Collateral identified and described in the Security Agreement and such Financial Statement. Upon due and proper filing of the PHPA Financing Statement with the office of the Secretary of State of the State of Indiana the security interests of the Collateral Agent under the Security Agreement in the personal property Collateral of PHPA identified and described therein and in such Financing Statement will be perfected to the extent that a security interest in such Collateral can be perfected by the filing of a UCC-1 financing statement in such office.

8. To our knowledge, no action, suit, other legal proceeding, arbitration proceeding or investigation is pending by or before any court or governmental authority or in any formal arbitration, or is overtly threatened, against or affecting PHPA (a) as to which there is a reasonably possibility of an adverse determination and that, if adversely determined, would reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect, or (b) that involves the Transaction Documents.

This opinion is predicated solely upon laws and regulations in effect in the State of Indiana (excluding political subdivisions thereof) as of the current date and as they currently apply. We are members of the bar of the State of Indiana, and express no opinion as to the laws of any other jurisdiction or as to any federal law. Further, we assume no responsibility to advise you of any change in law or fact first occurring after the date hereof.

Whenever, with respect to the existence or non-existence of facts, this opinion letter is qualified by the phrase “to our knowledge” or words of similar import, this qualification is

intended to signify that, during the course of our representation of PHPA, no information has come to the attention of attorneys currently practicing with our firm that would give us actual knowledge of the existence or non-existence of such facts. However, unless so stated, we have not undertaken any independent investigation to determine the existence or absence of such facts that would be contrary to the opinions expressed herein, and no inference as to the knowledge or the existence of such facts should be drawn from the fact of our representation of PHPA.

This opinion is delivered to you by us in our capacity as special Indiana counsel to PHPA solely for your reliance and is not to be used, circulated, quoted or otherwise referred to in any document or be furnished or relied upon by any other person for any purpose without our prior written consent; provided, however, it is understood that such other entities as shall become Lenders, Collateral Agents or Administrative Agents under the Agreement in connection with and pursuant to its terms may rely thereon, and is not to be made available to or relied upon any other Person, firm or entity without our prior written consent (provided that copies of this opinion letter may be made available to the counsel, assignees, transferees, participants and regulators of the addressees of this letter).

We have acted as special Wisconsin counsel to PacifiCare Health Systems, Inc., a Delaware corporation (the “Company”), in connection with that certain Credit Agreement dated as of the date hereof (the “Agreement”), among the Company, the Subsidiary Guarantors party thereto, the banks, financial institutions and other lenders party thereto (the “Lenders”), JPMorgan Chase Bank, N.A. (“JPMCB”), in its capacity as administrative agent for the benefit of the Lenders (in such capacity, the “Administrative Agent”) and JPMCB, in its capacity as collateral agent for the benefit of the Secured Parties (in such capacity, the “Collateral Agent”). All capitalized terms used but not defined herein shall have the respective meanings given to such terms in the Agreement.

This opinion is furnished to you at the request and on behalf of the Company pursuant to Section 5.01(b) of the Agreement, as special Wisconsin counsel, as to certain matters relating to American Medical Security Group, Inc., a Wisconsin corporation (“AMS”). AMS is a Subsidiary Guarantor.

In order to render the opinions expressed below, we have examined, are familiar with, and have relied upon, originals or copies, certified or otherwise identified to our satisfaction, of the following documents:

Items (I) through (III) above are hereinafter from time to time collectively referred to as the “Transaction Documents.” Items (IV) and (V) are hereinafter from time to time collectively referred to as the “Organizational Documents.” Items (I) through (VIII) above and the Officer’s Certificate (defined below) are hereinafter from time to time collectively referred to as the “Opinion Documents.” In our examination of the Opinion Documents and in rendering the opinions expressed below, we have assumed, without investigation, verification or inquiry: (a) the genuineness and authenticity of all signatures, (b) the authenticity and completeness of all agreements, documents, certificates and instruments submitted to us as originals; (c) the conformity to originals of all agreements, documents, certificates and instruments submitted to us as certified, conformed or photostatic copies; (d) the accuracy, completeness and authenticity of certificates of public officials; (e) the due organization or formation, valid existence and good standing in the jurisdiction of organization and the corporate or similar power to enter into and perform the Transaction Documents in accordance with their respective terms, of all Persons party to any Transaction Document (except that such assumption is not made as to the due incorporation and valid existence in the State of Wisconsin and corporate power of AMS); (f) the due authorization, execution and delivery of all Transaction Documents (except that such assumption is not made as to the due authorization, execution and delivery by AMS of the Transaction Documents) in each case where the authorization, execution and delivery thereof by the parties are prerequisites to the effectiveness of such documents; (g) the legal capacity of all individuals executing and delivering

documents to so execute and deliver at the time of such execution and delivery; (h) that the Transaction Documents are valid and binding obligations, enforceable in accordance with their respective terms against all Persons party thereto (except that such assumption is not made as to AMS with respect to the Transactions Documents); (i) that there is no oral or written extrinsic agreement or understanding, course of dealing, or usage of trade that would modify or interpret the terms of the Transaction Documents or the respective rights or obligations of the parties thereunder or that would have an effect on the opinions expressed herein and that there has been no waiver of any of the provisions of the Transaction Documents by conduct of the parties or otherwise; (j) that there are no judgments, decrees or orders that impair or limit the ability of AMS to enter into, execute and deliver, and perform, observe, and be bound by the Transaction Documents and the transactions contemplated therein (however, we have no knowledge of any such judgments, decrees, or orders); and (k) that all material terms and conditions of the relevant transactions are correctly and completely reflected in the Transaction Documents. We understand that the loans to be made pursuant to the Agreement will be used, in part, to refinance the indebtedness of AMS under its existing bank credit facility and for the working capital requirements of AMS.

As to factual matters material to this opinion, we have relied, with your permission and without independent investigation, upon a certificate (the “Officer’s Certificate”) of the Chairman, President and Chief Executive Officer of AMS (a copy of which is attached hereto). For purposes of this opinion, we have also assumed that, following the consummation of the Agreement, the Company and AMS will comply with all post-transaction reporting that may be required by federal, state or local law.

We express no opinion herein with respect to the creation or attachment of the security interests granted in the Security Agreement (which we understand to be addressed in the separate opinion letter to be delivered by Cooley Godward LLP) or as to the priority of any such security interests.

Based upon and subject to the foregoing, and subject to the additional qualifications set forth at the end of this opinion, we are of the opinion that:

1. Based solely on the certificate of the DFI referenced at (VI) above, AMS is a corporation validly existing under the laws of the State of Wisconsin, has filed its most recent required annual report, and has not filed articles of dissolution, with the DFI.

2. AMS has the corporate power to enter into and perform its obligations under the Transaction Documents and to own, lease and license its properties and to transact business in the State of Wisconsin.

3. The execution, delivery and performance by AMS of each of the Transaction Documents have been duly authorized by all requisite corporate action on the part of AMS and do not require any further approval of its directors or shareholders.

5. Each of the Transaction Documents constitutes a valid and binding obligation of AMS, enforceable against AMS in accordance with its terms.

6. No consents, approvals, authorizations, registrations, declarations or filings are required to be obtained or made by AMS under any Wisconsin law in order for AMS to execute, deliver or perform its payment obligations under the Transaction Documents except (a) such as have been duly obtained or made and are in full force and effect, (b) such filings and

other actions as may be required to perfect any lien or security interest which any such agreement purports to create, and (c) such as may be required by orders, decrees and the like that are specifically applicable to AMS and of which we have no knowledge.

7. The execution and delivery by AMS of each of the Transaction Documents and the performance as of the Effective Date by AMS of the Transaction Documents will not violate or contravene or be in conflict with, or require any consent or approval under: (a) any provision of the Organizational Documents or (b) any provision of Wisconsin or United States federal law which is known by us to be applicable to AMS in commercial transactions of the nature contemplated by the Transaction Documents.

8. The Financing Statement is in form sufficient (a) for filing with the DFI, and (b) to perfect the security interest of the Collateral Agent for the Secured Parties in that portion of the personal property Collateral of AMS identified and described in the Security Agreement and the Financing Statement in which a security interest is perfected by filing a financing statement in Wisconsin (the “Wisconsin Filing Collateral”). Upon due and proper filing of the Financing Statement with the DFI, the security interests of the Collateral Agent under the Security Agreement in the Wisconsin Filing Collateral, if attached, will be perfected to the extent that a security interest in such Collateral can be perfected by the filing of a UCC-1 financing statement in such office.

The foregoing opinions are subject to the following additional assumptions and qualifications:

A. Whenever we indicate that our opinion with respect to the existence or absence of facts is “to our knowledge” or the like, our opinion is, with your permission, based solely on the Officer’s Certificate and the current conscious awareness of facts or other information of the attorneys currently within our firm who have represented the Company in connection with the financing transactions contemplated by the Transaction Documents or in connection with the AMS Acquisition.

(i) Applicable bankruptcy, receivership, reorganization, insolvency, moratorium, fraudulent conveyance or transfer, and other laws and judicially developed doctrines relating to or affecting creditors’ or secured creditors’ rights and remedies generally;

(ii) General principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law, and limitations on the availability of specific performance, injunctive relief, and other equitable remedies;

(iii) The possibility that certain rights, remedies, waivers, and other provisions of the Transaction Documents may not be enforceable; nevertheless, such unenforceability will not render any of the Transaction Documents invalid as a whole and each of the Transaction Documents contains legally adequate provisions for the realization of the principal legal rights and benefits afforded by it; and

(iv) The requirement that the enforcing party act in a commercially reasonable manner and in good faith in exercising its rights under the Transaction Documents and comply

with the provisions of part 6 of article 9 of the Uniform Commercial Code as currently in effect in the State of Wisconsin (the “Wisconsin UCC”).

C. Except for our review of the Opinion Documents, we have not examined the records of any Lender, the Collateral Agent, the Administrative Agent, the Borrower, any Subsidiary Guarantor, or any court or any public, quasi-public, private, or other office in any jurisdiction or the files of our firm, and our opinions are subject to matters that an examination of such records would reveal.

D. Our security interest opinion in paragraph 8 is limited to perfection of a security interest by filing under article 9 of the Wisconsin UCC, and therefore that paragraph does not address (i) laws of jurisdictions other than Wisconsin or laws of Wisconsin except for article 9 of the Wisconsin UCC, (ii) collateral of a type not subject to article 9 of the Wisconsin UCC, or (iii) under Wisconsin UCC §§ 9-301 through 9-307, what law governs perfection, the effect of perfection or non-perfection, or priority of the security interests granted in the collateral covered by this opinion letter, except as provided in sections 9-301(1) and 9-307(5) with respect to registered organizations.

E. We express no opinion with respect to fixtures, consumer goods, investment property in a consumer transaction, as-extracted collateral, timber to be cut, commercial tort claims, or goods represented by a certificate of title.

F. In the case of proceeds, continuation of perfection of Collateral Agent’s security interest therein is limited to the degree set forth in section 9-315 of the Wisconsin UCC.

G. We call to your attention that in the case of property which becomes collateral after the date hereof, section 547 of the United States Bankruptcy Code (the “Code”) provides that a transfer is not made until the debtor has rights in the property transferred, so a security interest in after-acquired property may be treated as a voidable preference under the conditions (and subject to the exceptions) provided by section 547, and section 552 of the Code limits the extent to which property acquired by a debtor after the commencement of a case under the Code may be subject to a security interest arising from a security agreement entered into by the debtor before the commencement of such case.

H. We have made no examination of, and express no opinion as to, (a) the adequacy of any description of collateral, (b) title to the collateral described in the Transaction Documents or the existence of any liens, charges, or encumbrances thereon, or (c) the priority of the security interests or mortgage liens created or evidenced by any of the Transaction Documents.

I. With respect to our opinions in paragraphs 6 and 7(b), we express no opinion as to compliance by AMS with laws, statutes, and regulations generally applicable to the conduct of its business or as to consents, approvals, or other actions by regulatory authorities generally required for the conduct of its business.

J. We have not reviewed for purposes of our opinions, and nothing herein shall be construed as an opinion by us as to compliance with, applicable environmental or zoning laws, ordinances, rules, or regulations, federal, state, and local taxation, securities or “blue sky” rules and regulations, labor, ERISA, and other employee-benefit laws, or antitrust laws.

K. We express no opinion as to any actions that may be required to be taken under the Wisconsin UCC or other applicable law in order for the effectiveness of the AMS Financing Statement, or the validity or perfection of any security interest, to be maintained.

L. With reference to the various provisions of the Transaction Documents which recognize the potential need for approval of Insurance Regulators prior to the exercise of certain rights under the Transaction Documents, we inform you that prior to enforcing any security interest in shares of a Wisconsin insurance company subsidiary (including by transferring such shares to or registering such shares in the name of the Collateral Agent, or exercising foreclosure, voting, assignment or other rights with respect to such shares) the Collateral Agent will be required to obtain the approval of the Wisconsin Office of the Commissioner of Insurance.

This opinion is predicated solely upon laws and regulations in effect in the State of Wisconsin (excluding political subdivisions thereof) and, with respect to the opinion given in paragraph 7(b), United States federal laws and regulations, in each case as of the current date and as they currently apply. We are members of the bar of the State of Wisconsin, and we express no opinion as to the laws of any other jurisdiction or as to any federal law (except with respect to the opinion given in paragraph 7(b)). In that regard, we note that the Transaction Documents contain provisions to the effect that the laws of jurisdictions other than Wisconsin are intended to be governing. For the purposes of our opinions herein, we have assumed, without any independent investigation, that the laws of all jurisdictions that may govern the Transaction Documents, and all other issues relevant to this opinion, are identical in all relevant respects to the laws of the State of Wisconsin. Further, we assume no responsibility to advise you of any change in law or fact first occurring after the date hereof.

This opinion is limited to the matters set forth herein, and no opinion may be inferred or implied beyond the matters expressly contained herein. This opinion is delivered to you by us in our capacity as special Wisconsin counsel to the Company solely for your reliance and the reliance of such other entities as shall become Lenders, Collateral Agents or Administrative Agents under the Agreement. This opinion letter is not to be made available to or relied upon by any other Person, firm or entity without our prior written consent (provided, that copies of this opinion letter may be made available to the counsel, assignees, transferees, participants and regulators of the addressees of this letter).

We have acted as special New York counsel to JPMorgan Chase Bank, N.A. (“JPMCB”) in connection with the Credit Agreement (the “Credit Agreement”) dated as of December 13, 2004, between PacifiCare Health Systems, Inc. (the “Borrower”), the Subsidiary Guarantors party thereto, the Lenders party thereto, JPMCB, as Administrative Agent, and JPMCB, as Collateral Agent, providing for extensions of credit to be made by the Lenders to the Borrower in an aggregate principal or face amount not exceeding $825,000,000. Except as otherwise provided herein, terms defined in the Credit Agreement are used herein as defined therein. This opinion letter is being delivered pursuant to Section 5.01(c) of the Credit Agreement.

In rendering the opinions expressed below, we have examined the Credit Agreement and the Security Agreement (collectively the “Credit Documents”). The Borrower and the Subsidiary Guarantors party thereto are herein collectively referred to as the “Obligors”.

In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with authentic original documents of all documents submitted to us as copies. When relevant facts were not independently established, we have relied upon representations made in or pursuant to the Loan Documents.

(i) the Credit Documents have been duly authorized by, have been duly executed and delivered by, and (except to the extent set forth in the opinions expressed below as to the Obligors) constitute legal, valid, binding and enforceable obligations of, all of the parties thereto;

(iii) all such parties are duly organized and validly existing and have the power and authority (corporate or other) to execute, deliver and perform the same.

Based upon and subject to the foregoing and subject also to the comments and qualifications set forth below, and having considered such questions of law as we have deemed necessary as a basis for the opinions expressed below, we are of the opinion that each Credit Document constitutes the legal, valid and binding obligation of each Obligor party thereto, enforceable against such Obligor in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or other similar laws relating to or affecting the rights of creditors generally and except as the enforceability thereof is subject to the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including (a) the possible unavailability of specific performance, injunctive relief or any other equitable remedy and (b) concepts of materiality, reasonableness, good faith and fair dealing.

The foregoing opinions are subject to the following comments and qualifications:

(A) The enforceability of Sections 3.03 and 10.03 of the Credit Agreement (and similar provisions of the Security Agreement) may be limited by (i) laws rendering unenforceable indemnification contrary to Federal or state securities laws and the public policy underlying such laws and (ii) laws limiting the enforceability of provisions exculpating or exempting a party, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves gross negligence, recklessness, willful misconduct or unlawful conduct.

(B) The enforceability of provisions in each Credit Document to the effect that terms may not be waived or modified except in writing may be limited under certain circumstances.

(C) We express no opinion as to (i) the effect of the laws of any jurisdiction in which any Lender is located (other than the State of New York) that limit the interest, fees or other charges such Lender may impose for the loan or use of money or other credit, (ii) the last sentence of Section 2.16(d) of the Credit Agreement, (iii) Section 3.06 of the Credit Agreement, (iv) Section 3.09 of the Credit Agreement, (v) the last sentence of Section 10.04(c)(i) of the Credit Agreement, (vi) Section 10.08 of the Credit Agreement, (vii) the first sentence of Section 10.09(b) of the Credit Agreement, insofar as such sentence relates to the subject-matter jurisdiction of the United States District Court for the Southern District of New York to adjudicate any controversy related to the Credit Agreement, or (viii) the waiver of inconvenient forum set forth in Section 10.09(c) of the Credit Agreement with respect to proceedings in the United States District Court for the Southern District of New York.

(D) Section 3.02 of the Credit Agreement may not be enforceable to the extent that the Guaranteed Obligations are materially modified.

(E) We express no opinion as to the applicability to the obligations of the Subsidiary Guarantors of (or the enforceability of such obligations under) Section 548 of the Bankruptcy Code, Article 10 of the New York Debtor and Creditor Law or any other provision of law relating to fraudulent conveyances, transfers or obligations, or the provisions of the laws of the jurisdiction of incorporation of the Subsidiary Guarantors restricting dividends, loans or other distributions by a corporation for the benefit of its stockholders.

(F) We wish to point out that the obligations of the Obligors party thereto, and the rights and remedies of the Secured Parties, under the Security Agreement may be subject to possible limitations upon the exercise of remedial or procedural provisions contained therein, provided that such limitations do not, in our opinion (but subject to the other comments and qualifications set forth in this opinion letter), make the remedies and procedures that will be afforded to the Collateral Agent inadequate for the practical realization of the substantive benefits purported to be provided by the Security Agreement.

(G) We express no opinion as to the existence of, or the right, title or interest of any Obligor in, to or under, any of the Collateral, and we express no opinion as to the creation, perfection or priority of any security interest in any of the Collateral.

(H) We wish to point out that the acquisition by an Obligor after the initial extension of credit under the Credit Agreement of an interest in property that becomes subject to the lien of the Security Agreement may constitute a voidable preference under Section 547 of the Bankruptcy Code.

The foregoing opinions are limited to matters involving the Federal laws of the United States of America and the law of the State of New York, and we do not express any opinion as to the laws of any other jurisdiction.

At the request of our client, this opinion letter is, pursuant to Section 5.01(c) of the Credit Agreement, provided to you by us in our capacity as special New York counsel to JPMCB and may not be relied upon by any Person for any purpose other than in connection with the transactions contemplated by the Credit Documents without, in each instance, our prior written consent.
