WHEREAS, the Borrower, the Servicer, the VFCC Group, the Gotham Group and the Administrative Agent wish to amend and restate the Existing Agreement in its entirety, on the terms and subject to the conditions hereinafter set forth;

NOW, THEREFORE,in consideration of the premises and the mutual agreements herein contained, the parties hereto agree as follows:

ARTICLE I.
THE CREDIT

Section 1.1 The Facility. On the terms and subject to the conditions set forth in this Agreement, the Borrower (or the Servicer on the Borrower’s behalf) may from time to time during the Revolving Period for each Group request Advances by delivering a Borrowing Request to the applicable Co-Agent(s) in accordance with Section 2.1. Upon receipt of a copy of each Borrowing Request from the Borrower or Servicer during a Group’s Revolving Period, each applicable Co-Agent shall determine whether its Conduit will fund a Loan in an amount equal to the portion of the requested Advance specified in such Borrowing Request, and

(a)in the event that VFCC elects not to make any such Loan to the Borrower, the VFCC Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks of VFCC severally agrees to make its Ratable Share of such Loan to the Borrower, on the terms and subject to the conditions hereof,provided that at no time may the aggregate principal amount of VFCC’s and its Liquidity Banks’ Loans at any one time outstanding exceed the lesser of (i) the aggregate amount of the VFCC Liquidity Banks’ Commitments, and (ii) the VFCC Group’s Percentage of the Borrowing Base (such lesser amount, the“VFCC Allocation Limit”);

(b)in the event that Gotham elects not to make any such Loan to the Borrower, the Gotham Agent shall promptly notify the Borrower and, unless the Borrower cancels its Borrowing Request, each of the Liquidity Banks of Gotham severally agrees to make its Ratable Share of such Loan to the Borrower, on the terms and subject to the conditions hereof,provided that at no time may the aggregate principal amount of Gotham’s and its Liquidity Banks’ Loans at any one time outstanding exceed the lesser of (i) the aggregate amount of the Gotham Liquidity Banks’ Commitments, and (ii) the Gotham Group’s Percentage of the Borrowing Base (such lesser amount, the“Gotham Allocation Limit”).

Each Loan shall be in the minimum amount of $1,000,000 or a larger integral multiple of $500,000. In no event may the aggregate principal amount of the Advances hereunder exceed the lesser of (x) the Aggregate Commitment, or (y) the Borrowing Base. Each Liquidity Bank’s Commitment under this Agreement shall terminate on the earlier to occur of such Liquidity Bank’s Scheduled Termination Date and the Termination Date. Each of the Loans, and all other Obligations of the Borrower, shall be secured by the Collateral as provided in Article IX.

Section 1.2 Funding Mechanics; Liquidity Fundings.

(a)Prior to the VFCC Group’s Termination Date, each Advance hereunder shall consist of Loans made by (i) Gotham and/or its Liquidity Banks, and/or (ii) VFCC and/or its Liquidity Banks, and which (except for any Advance which does not increase the aggregate principal amount of the Loans outstanding) shall be made in such proportions by each Group such that, after giving effect thereto, the aggregate outstanding principal balance of the Loans outstanding from each Group shall be in proportion to such Group’s Commitment Percentage. Any Advance which does not increase the aggregate principal amount outstanding may be funded solely by one or more of the members of each Group. From and after the VFCC Group’s Termination Date, each Advance hereunder shall consist of Loans made solely by Gotham and/or its Liquidity Banks.

(b)Each Lender funding any Loan (or portion thereof) shall wire transfer the principal amount thereof to its applicable Co-Agent in immediately available funds not later than 12:00 noon (New York City time) on the applicable Borrowing Date and, subject to its receipt of such Loan proceeds, such Co-Agent shall wire transfer such funds to the account specified by the Borrower in its Borrowing Request not later than 2:00 p.m. (New York City time) on such Borrowing Date.

(c)While it is the intent of each of the Conduits to fund its respective Loans through the issuance of Commercial Paper Notes, the parties acknowledge that if either of the Conduits is unable, or determines that it is undesirable, to issue Commercial Paper Notes to fund all or any portion of its Loans at a CP Rate, or is unable to repay such Commercial Paper Notes upon the maturity thereof, such Conduit may sell all or any portion of its Loans (or interests therein) to its Liquidity Banks at any time pursuant to its Liquidity Agreement to finance or refinance the necessary portion of its Loans through a Liquidity Funding to the extent available. The Liquidity Fundings may be Alternate Base Rate Loans or Eurodollar Loans, or a combination thereof, selected by the Borrower in accordance with Article II. In addition, the parties acknowledge that Commercial Paper Notes are issued at a discount and at varying discount rates; accordingly, it may not be

possible for all CP Rate Loans to be made in amounts precisely equal to the amounts specified in a Borrowing Request. Regardless of whether a Liquidity Funding constitutes an assignment of a Loan or the sale of one or more participations therein, each Liquidity Bank participating in a Liquidity Funding shall have the rights of a “Lender” hereunder with the same force and effect as if it had directly made a Loan to the Borrower in the amount of its Liquidity Funding.

(d)Nothing herein shall be deemed to commit any Lender to make CP Rate Loans.

Section 1.3 Interest Rates.

(a)Each CP Rate Loan shall bear interest on the outstanding principal amount thereof from and including the first day of the CP Tranche Period applicable thereto selected in accordance with Article II of this Agreement to (but not including) the last day of such CP Tranche Period at the applicable CP Rate. On the 5th Business Day immediately preceding each Settlement Date, each Pool Funded Conduit shall calculate the aggregate amount of CP Costs for the applicable Accrual Period and shall notify the Borrower of its aggregate amount of such CP Costs which shall be payable on such Settlement Date. At any time while Gotham is not acting as Pool Funded Conduit, on the 5th Business Day immediately preceding each Settlement Date, the Gotham Agent shall calculate Gotham’s CP Rate and each shall notify Borrower of the aggregate amount of CP Costs which shall be payable on such Settlement Date.

(b)Each Eurodollar Loan shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto selected in accordance with Article II of this Agreement to (but not including) the last day of such Interest Period at a rateper annum equal to the sum of (i) the applicable Eurodollar Rate (Reserve Adjusted) for such Interest Period plus (ii) the Applicable Percentageper annum.

(c)Each Alternate Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Loan is made to but excluding the date it is paid at a rateper annum equal to the Alternate Base Rate for such day. Changes in the rate of interest on Alternate Base Rate Loans will take effect simultaneously with each change in the Alternate Base Rate.

(d)Notwithstanding anything to the contrary contained in Sections 1.3(a), (b) or (c), upon the occurrence of an Event of Default, and during the continuance thereof, all Obligations shall bear interest, payable upon demand, at the Default Rate.

(e)Interest shall be payable for the day a Loan is made but not for the day of any payment on the amount paid if payment is received prior to 1:00 p.m. (local time) at the place of payment. If any payment of principal of or interest on a Loan shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment.

Section 1.4 Payment Dates; Absence of Notes to Evidence Loans.

(a)The Borrower promises to pay the principal of each CP Rate Loan outstanding from each of the Conduits on the applicable Termination Date.

(b)The Borrower promises to pay the principal of each Eurodollar Loan (if any) outstanding from each of the Liquidity Banks on or before the earliest to occur of (i) the applicable Termination Date, (ii) such Liquidity Bank’s Scheduled Termination Date, and (iii) the refinancing of such Loan with a CP Rate Loan or an Alternative Base Rate Loan.

(c) In addition to the foregoing, on each Business Day occurring on or after the last day of a Group’s Revolving Period, the Borrower promises to pay a portion of the principal of the Loans outstanding from such Group equal to such Group’s Percentage of the Collections.

(d)The Borrower promises to pay the principal of each Alternate Base Rate Loan (if any) outstanding from each of the Liquidity Banks on or before the earliest to occur of (i) the Termination Date, (ii) such Liquidity Bank’s Scheduled Termination Date, and (iii) the refinancing of such Loan with a CP Rate Loan or a Eurodollar Rate Loan.

(e)The Borrower promises to pay all accrued and unpaid interest on each Loan on its applicable Interest Payment Date.

(f)Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. Upon request of the Borrower, such Lender’s Co-Agent or the Administrative Agent, such Lender will confirm the outstanding principal balances of its Loans and the amount of any accrued and unpaid interest thereon. The entries maintained in the accounts maintained pursuant to this Section shall beprima facie evidence of the existence and amounts of the Obligations therein recorded;provided, however, that the failure of any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

Section 1.5 Prepayments. Subject, in the case of CP Rate Loans and Eurodollar Loans, to the funding indemnification provisions of Section 4.3:

(a)The Borrower may from time to time voluntarily prepay, without penalty or premium, all outstanding Advances, or, in a minimum aggregate amount of $2,000,000 (or a larger integral multiple of $1,000,000), any portion of the outstanding Advances by giving prior written notice to the Co-Agents: (i) given within the Required Notice Period with respect to each Pool Funded Conduit’s Loans so prepaid and (ii) at any time while Gotham is not a Pool Funded Conduit, providing for such prepayment to occur on the last day of the CP Tranche Period with respect to Gotham’s CP Rate Loans so prepaid (each, a“Prepayment Notice”);provided that each such prepayment of principal is accompanied by a payment of all accrued and unpaid interest on the amount prepaid, together with all amounts (if any) due under Section 4.3, and except as provided in

Section 14.1(c) and in the definitions of“Approved Amendment”and“Termination Date,” is made between the Groups in such proportions so that after giving effect thereto, the aggregate outstanding principal balance of the Loans outstanding from each Group shall be in proportion to the Groups’ respective Commitment Percentages.

(b)If, on any Business Day, the aggregate outstanding principal amount of the Loans from the VFCC Group exceeds the VFCC Allocation Limit, or the aggregate principal amount of the Loans outstanding from VFCC exceeds the VFCC Liquidity Banks’ Liquidity Commitments divided by 102%, the Borrower shall prepay such Loans by wire transfer to the VFCC Agent received not later than 12:00 noon (New York City time) on the first Business Day thereafter of an amount sufficient to eliminate such excess, together with accrued and unpaid interest on the amount prepaid.

(c)If, on any Business Day, the aggregate outstanding principal amount of the Loans from the Gotham Group exceeds the Gotham Allocation Limit, or the aggregate principal amount of the Loans outstanding from Gotham exceeds the Gotham Liquidity Banks’ aggregate Liquidity Commitments divided by 102%, the Borrower shall prepay such Loans by wire transfer to the Gotham Agent received not later than 12:00 noon (New York City time) on the first Business Day thereafter of an amount sufficient to eliminate such excess, together with accrued and unpaid interest on the amount prepaid.

(d)Upon receipt of any wire transfer pursuant to Section 1.5(a), (b) or (c), the applicable Co-Agent shall wire transfer to each of its Constituent Lenders their respective shares thereof not later than 1:00 p.m. (New York City time) on the date when received. Any prepayment required pursuant to Section 1.5(b) or (c) shall be appliedfirst, to the ratable reduction of the applicable Group’s Alternate Base Rate Loans outstanding,second, to the ratable reduction of the applicable Group’s Eurodollar Loans outstanding, andlastly, to the reduction of the applicable Group’s CP Rate Loans selected by the Borrower (or the Servicer, on the Borrower’s behalf).

(e)Unless each of the Co-Agents in its sole discretion shall otherwise agree, not more than three (3) Advances and/or prepayments pursuant to Section 1.5(a) may occur, in the aggregate, in any calendar week.

Section 1.6 Reductions in Aggregate Commitment. The Borrower may permanently reduce the Aggregate Commitment in whole, or ratably between the Groups in part, in a minimum amount of $10,000,000 (or a larger integral multiple of $1,000,000), upon at least fifteen (15) Business Days’ written notice to the Co-Agents (each, a “Commitment Reduction Notice”), which notice shall specify the aggregate amount of any such reduction and the VFCC Liquidity Banks’ and the Gotham Liquidity Banks’ respective Commitment Percentages thereof,provided, however, that (a) the amount of the Aggregate Commitment may not be reduced below the aggregate principal amount of the outstanding Advances, and (b) the amount of the Aggregate Commitment may not be reduced below $100,000,000 unless the Aggregate Commitment is terminated in full. All accrued and unpaid fees shall be payable on the effective date of any termination of the Aggregate Commitment. Each Commitment Reduction Notice shall be irrevocable once delivered to the Co-Agents.

Section 1.7 Distribution of Certain Notices; Notification of Interest Rates. Promptly after receipt thereof, the VFCC Agent will notify the VFCC Group and the Gotham Agent will notify the Gotham Group, of the contents of each Monthly Report, Weekly Report, Borrowing Request, Commitment Reduction Notice, Prepayment Notice or notice of default received by it from the Borrower or the Servicer hereunder. In addition, each of the Co-Agents shall promptly notify its Constituent Lenders and the Borrower of each determination of and change in Interest Rates.

ARTICLE II.
BORROWING AND PAYMENT MECHANICS; CERTAIN COMPUTATIONS

Section 2.1 Method of Borrowing. The Borrower (or the Servicer, on the Borrower’s behalf) shall give the Co-Agents irrevocable notice in the form of Exhibit 2.1 hereto (each, a“Borrowing Request”) not later than 12:00 noon (New York City time) at least two (2) Business Days before the Borrowing Date of each Advance. On each Borrowing Date, each applicable Lender shall make available its Loan or Loans in immediately available funds to its Co-Agent by wire transfer of such amount received not later than 1:00 p.m. (New York City time). Subject to its receipt of such wire transfers, each Co-Agent will wire transfer the funds so received from its Constituent Lenders to the Borrower at the account specified in its Borrowing Request not later than 2:00 p.m. (New York City time) on the applicable Borrowing Date. Unless each of the Co-Agents in its sole discretion shall otherwise agree, not more than three (3) Advances and/or prepayments pursuant to Section 1.5 may occur, in the aggregate, in any calendar week.

Section 2.2 Selection of CP Tranche Periods and Interest Periods.

(a)Except upon the occurrence and during the continuance of an Event of Default or when Gotham is a Pool Funded Conduit, the Borrower (or the Servicer, on the Borrower’s behalf) in its Borrowing Request may request CP Tranche Periods from time to time to apply to Gotham’s CP Rate Loans;provided, however, that (i) at any time while Gotham has CP Rate Loans outstanding, at least one CP Tranche Period of Gotham shall mature on each Settlement Date and (ii) no CP Tranche Period of Gotham may extend beyond the latest Scheduled Termination Date of any Gotham Liquidity Bank. In addition to the foregoing, except upon the occurrence and during the continuance of an Event of Default, the Borrower (or the Servicer, on the Borrower’s behalf) in its Borrowing Request may request Interest Periods from time to time to apply to the Eurodollar Loans;provided, however, that (x) at any time while any Lender has Eurodollar Loans outstanding, at least one Interest Period of such Lender shall mature on each Settlement Date and (y) no Interest Period of any Lender which began prior to its Scheduled Termination Date shall extend beyond such Scheduled Termination Date.

(b)While the Gotham Agent will use reasonable efforts to accommodate the Borrower’s or the Servicer’s requests for CP Tranche Periods except during the continuance of an Event of Default or when Gotham is acting as Pool Funded Conduit, the Gotham Agent shall have the right to subdivide any requested CP Rate Loan into one or more CP Rate Loans of different CP Tranche Periods, or, if the requested period is not feasible, to suggest an alternative CP Tranche Period. While each of the Co-Agents will use reasonable efforts to accommodate the Borrower’s or the Servicer’s requests for

Interest Periods for Eurodollar Loans except during the continuance of an Event of Default, each of the Co-Agents shall have the right to subdivide any requested Eurodollar Loan into one or more Eurodollar Loans with different Interest Periods, or, if the requested period is not feasible, to suggest an alternative Interest Period. Notwithstanding the foregoing, not less than $1,000,000 of principal may be allocated to any CP Tranche Period or Interest Period of any Lender, and no Alternate Base Rate Loan may have a principal amount of less than $1,000,000.

(c)The Borrower (or the Servicer, on the Borrower’s behalf) may not request an Interest Period for a Eurodollar Loan unless it shall have given each of the applicable Co-Agent(s) written notice of its desire therefor not later than 12:00 noon (New York City time) at least three (3) Business Days prior to the first day of the desired Interest Period. Accordingly, all Liquidity Fundings shall initially be Alternate Base Rate Loans.

(d)Unless each Co-Agent shall have received written notice by 12:00 noon (New York City time) on the Required Day prior to the last day of a CP Tranche Period that the Borrower intends to reduce the aggregate principal amount of the CP Rate Loans outstanding, each of the Co-Agents and the Conduits shall be entitled to assume that the Borrower desires to refinance the principal and interest of each maturing CP Rate Loan on the last day of its CP Tranche Period with new CP Rate Loans having substantially similar CP Tranche Periods;provided, however, that the Borrower shall remain liable to pay in cash any portion of the principal or interest on the maturing CP Rate Loan when due to the extent that the applicable Conduit cannot issue Commercial Paper Notes or avail itself of a Liquidity Funding, in either case, in the precise amount necessary to refinance the maturing CP Rate Loan and the accrued and unpaid interest thereon.

(a)the outstanding aggregate balance of the Net Receivables as reflected in the preceding Monthly Report (net of any positive adjustments) has been reduced for any of the following reasons:

(ii)shall impose, modify or deem applicable any reserve that was not included in the computation of the applicable Interest Rate, or any special deposit or similar requirement against assets of any Affected Party, deposits or obligations with or for the account of any Affected Party or with or for the account of any affiliate (or entity deemed by the Federal Reserve Board to be an affiliate) of any Affected Party, or credit extended by any Affected Party; or

(b)Each Affected Party will promptly notify the Borrower, the Administrative Agent and the applicable Co-Agent of any event of which it has knowledge (including any future event that, in the judgment of such Affected Party, is reasonably certain to occur) which will entitle such Affected Party to compensation pursuant to this Section 4.2;provided, however, no failure to give or delay in giving such notification shall adversely affect the rights of any Affected Party to such compensation unless such notification is given more than 90 days after the Affected Party becomes aware of such Regulatory Change.

(c)In determining any amount provided for or referred to in this Section 4.2, an Affected Party may use any reasonable averaging and attribution methods (consistent with its ordinary business practices) that it (in its reasonable discretion) shall deem applicable.

If such proposed Eligible Assignee is acceptable to the applicable Co-Agent (who shall not unreasonably withhold or delay its approval), the claiming Lender will be obligated to assign all of its rights and obligations to such proposed Eligible Assignee within ten (10) Business Days after such Co-Agent gives its consent to such proposed Eligible Assignee. In addition, if one or more Affected Parties in one of the Groups (but not both of the Groups) requests compensation under Section 4.2(a), the Borrower shall have the right to (i) require all members of the Group to which such claiming part to assign all, but not less than all, of their Commitment(s) and outstanding Obligations, as applicable, by entering into written assignments with one or more Eligible Assignees identified by the Borrower, or (ii) to pay in full of all Obligations (if any) owing to such Group and terminate its Commitment(s) (as applicable). Each assignment pursuant to clause (i) above to an Eligible Assignee (which may include a Constituent of the other Co-Agent) shall become effective on the date specified therein subject to receipt of payment in full on such date for all Obligations, if any, owing to the Group being replaced, and the Group being replaced shall make the requested assignments;provided that any expenses or other amounts which would be owing to such Group pursuant to any indemnification provision hereof shall be payable by the Borrower as if the Borrower had prepaid the Loans of the assigning Group rather than the members of such Group having assigned their respective interests hereunder

Section 4.3 Funding Losses. In the event that any Lender shall actually incur any actual loss or expense (including any actual loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to make or maintain any Loan or Liquidity Funding) as a result of (i) any payment of principal with respect to such Lender’s Loan or Liquidity Funding being made on any day other than the scheduled last day of an applicable CP Tranche Period or Interest Period with respect thereto, including, without limitation, because of a payment required by Section 1.4 or a prepayment required by Section 1.5(b), (c) or (d) (it being understood that the foregoing shall not apply to any Alternate Base Rate Loans), or (ii) any Loan not being made in accordance with a request therefor under Section 2.1, then, upon written notice from the applicable Co-Agent to the Administrative Agent, the Borrower and the Servicer, the Borrower shall pay to the Servicer, and the Servicer shall pay to the applicable Co-Agent for the account of such Lender, the amount of such actual loss or expense;provided, however,that in the case of any Pool Funded Conduit, nothing in this Section 4.3 shall duplicate any amount paid to it as Broken Funding Costs. Such written notice (which shall include the methodology for calculating, and the calculation of, the amount of such actual loss or expense, in reasonable detail) shall, in the absence of demonstrable error, be conclusive and binding upon the Borrower and the Servicer.

(h)Government Approvals. No authorizations, approvals or consents of, and no filings or registrations with, any Governmental Authority or any securities exchange are necessary for the execution, delivery or performance by any Loan Party of the Transaction Documents to which it is a party or for the legality, validity or enforceability hereof or thereof or for the consummation of the transactions herein and therein contemplated, except for filings and recordings in respect of the Liens created pursuant to the Transaction Documents (all of which have been duly made or delivered to the Administrative Agent’s counsel for filing or may be prepared by the Administrative Agent for filing in accordance with the terms of this Agreement) and except for consents, authorizations and filings that have been obtained or made and are in full force and effect or the failure of which to obtain would not have a Material Adverse Effect.

Each Loan Party understands that all such statements, representations and warranties shall be deemed to have been relied upon by the Lenders as a material inducement to make each extension of credit hereunder.

(ii)From December 31, 2007 through and including the date hereof, there has been no material adverse change in Quest Diagnostics’ consolidated financial condition, business or operations. Since December 31, 2007, there has been no material adverse change in Quest Diagnostics’ consolidated financial condition, business or operations that has had, or would reasonably be expected to have, a material adverse effect upon its ability to perform its obligations, as an Originator or as Servicer, under the Transaction Documents when and as required, and no material adverse effect on the collectibility of any material portion of the Receivables.

(iii)Since the date hereof, no event has occurred which would have a Material Adverse Effect.

(j)Nature of Receivables. Each Receivable constitutes an Account or a Payment Intangible.

(k)Margin Regulations. The use of all funds obtained by such Loan Party under this Agreement or any other Transaction Document will not conflict with or contravene any of Regulation T, U or X.

(l)Title to Receivables and Quality of Title.

(i)Each Receivable has been acquired by the Borrower from an Originator in accordance with the terms of the Sale Agreement, and the Borrower has thereby irrevocably obtained good title to such Receivable and its Related Assets, free and clear of all Adverse Claims (except as created under the Transaction Documents), and the Borrower has the legal right to sell and encumber, such Receivable and the Related Assets. Without limiting the foregoing, there have been duly filed or delivered to the Administrative Agent’s counsel in form suitable for filing, all financing statements and financing statements amendments or other similar instruments or documents necessary under the UCC of all appropriate jurisdictions to perfect the Borrower’s ownership interest in such Receivable.

(ii)This Agreement creates a valid security interest in the Collateral in favor of the Administrative Agent, for the benefit of the Secured Parties, and, upon filing of the financing statements and amendments described in clause (i), together with UCC termination statements delivered under the Receivables Sale Agreement, such security interest will be a first priority perfected security interest.

(iii)No financing statement executed or otherwise authorized by any Originator or Loan Party or other instrument similar in effect covering any portion of the Collateral is on file in any recording office except such as may be filed (A) in favor of an Originator in accordance with the Contracts, (B) in favor of the Borrower and its assigns in connection with the Sale Agreement, (C) in favor of the Administrative Agent in accordance with this Agreement, (D) in connection with any Lien arising solely as the result of any action taken by the Administrative Agent or one of the Secured Parties, or (E) which shall have been terminated or amended pursuant to UCC financing statements delivered to or prepared by the Administrative Agent hereunder in form suitable for filing in all applicable jurisdictions.

(m)Accurate Reports. No Monthly Report, Weekly Report or computation of Cash Collateral Payment (in each case, if prepared by such Loan Party, or to the extent information therein was supplied by such Loan Party), no other information, exhibit, schedule or information concerning the Collateral furnished or to be furnished verbally or in writing before or after the date of this Agreement, by or on behalf of such Loan Party to each of the Co-Agents or Lenders pursuant to this Agreement was inaccurate in any material respect as of the date it was dated or (except as otherwise disclosed to each of the Co-Agents or the Lenders at such time) as of the date so furnished, or contained or (in the case of information or other materials to be furnished in the future) will contain any material misstatement of fact or omitted or (in the case of information or other materials to be furnished in the future) will omit to state a material fact or any fact necessary to make the statements contained therein not materially misleading in light of the circumstances made or presented (it being understood that the Monthly Reports and Weekly Reports are not prepared in accordance with GAAP and that reports prepared in accordance with GAAP on the same subject matter might vary materially; and certain reconciling information with respect to Receivables will be set forth in the Monthly Report).

(n)Jurisdiction of Organization; Offices. Each Loan Party’s jurisdiction of organization is correctly set forth after its name in the preamble to this Agreement. The principal places of business and chief executive office of the Borrower is located at the addresses set forth

on Schedule 6.1(n), and the offices where the Servicer and the Borrower keep all their Records and material Contracts are located at the addresses specified in Schedule 6.1(n) (or at such other locations, notified to each of the Co-Agents in accordance with Section 7.1(f), in jurisdictions where all action required by Section 8.5 has been taken and completed).

(o)Lockboxes and Collection Accounts.

(i)One of the Loan Parties or the applicable Originator has instructed all Obligors of all Receivables to pay all Collections thereon either (A) by mail addressed to a Lockbox or (B) by wire transfer or other electronic funds transfer directly to a Collection Account in the name of the applicable Originator, as sub-servicer, or in the name of the Borrower. Items received in the Lockboxes are deposited for collection each Business Day into a Collection Account in the name of the applicable Originator or the Borrower, and all collected and available funds from time to time in each Collection Account in the name of any Originator are swept each day to a Collection Account in the name of the Borrower. Each of the agreements establishing and governing the maintenance of the Lockboxes and Collection Accounts is in full force and effect, and each of the Lockboxes and Collection Accounts is subject to a Collection Account Agreement that is in full force and effect.

(ii)The Borrower has not granted any Person other than the Administrative Agent, control of any Collection Account or any Lockbox, or the right to take control of any of the foregoing at a future time or upon the occurrence of a future event.

(iii)Except as otherwise provided in Section 7.3(d), each Collection Account Agreement, and the name and address of each Collection Bank (together with the account numbers of all Collection Accounts maintained with it and the address of each Lockbox maintained with it) are set forth on Schedule 6.1(o) .

(p)Eligible Receivables. Each Receivable included as an Eligible Receivable in the Net Pool Balance in connection with any computation or recomputation of the Borrowing Base is an Eligible Receivable on such date.

(q)ERISA. No ERISA Event has occurred or is reasonably expected to occur which could have a Material Adverse Effect. The present value of all accumulated benefit obligations of all underfunded Pension Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $20.0 million the fair market value of the assets of all such underfunded Pension Plans. Each ERISA Entity is in compliance in all material respects with the presently applicable provisions of ERISA and the Code with respect to each Employee Benefit Plan. Using actuarial assumptions and computation methods consistent with subpart 1 of subtitle E of Title IV of ERISA, the aggregate liabilities of any of each ERISA Entity to all Multiemployer Plans in the event of a complete withdrawal therefrom, as of the close of the most recent fiscal year of each such Multiemployer Plan, would not result in a Material Adverse Effect. All Foreign Plans are in substantial compliance with all Requirements of Law (other than to the extent such failure to comply would not reasonably be expected to have a Material Adverse Effect).

(r)Names. Since its incorporation, the Borrower has not used any legal names, trade names or assumed names other than (i) the name in which it has executed this Agreement, and (ii) any other name to which the Administrative Agent gives its prior written consent (which consent will not be unreasonably withheld or delayed).

(s)Credit and Collection Policy. With respect to the Receivables originated by each of the Originators, each of the applicable Originator, the Borrower and the Servicer has complied in all material respects with the applicable Credit and Collection Policy, and no change has been made to such Credit and Collection Policy since the date of this Agreement which would be reasonably likely to materially and adversely affect the collectibility of the Receivables or decrease the credit quality of any newly created Receivables except for such changes as to which each of the Co-Agents has received the notice required under Section 7.2(h) and has given its prior written consent thereto (which consent shall not be unreasonably withheld or delayed).

(t)Payments to Applicable Originator. With respect to each Receivable sold or contributed to the Borrower by any Originator under the Sale Agreement, the Borrower has given reasonably equivalent value to such Originator in consideration for such Receivable and the Related Assets with respect thereto and no such transfer is or may be voidable under any section of the Bankruptcy Reform Act of 1978 (11 U.S.C. §§101 et seq.), as amended.

(u)Investment Company Act; Public Utility Holding Company Act; OtherRestrictions. No Loan Party is an “investment company”, or a company “controlled” by an “investment company”, within the meaning of the United States Investment Company Act of 1940, as amended. No Loan Party is a “holding company”, or an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company”, within the meaning of the United States Public Utility Holding Company Act of 1935, as amended. No Loan Party is subject to regulation under any law or regulation which limits its ability to incur Indebtedness, other than Regulation X of the Board of Governors of the Federal Reserve System.

(v)Borrowing Base; Solvency. The Borrowing Base is at all times at least equal to the aggregate outstanding principal balance of the Advances. As of each Borrowing Date, after giving effect to any Loans to be borrowed on such date, the Borrower is and will be Solvent.

(f)Jurisdiction of Organization; Location of Records. Each Loan Party will keep its jurisdiction of organization, chief place of business and (at any time while the location of its chief executive office remains germane to perfection of any of the security interests or ownership interests purported to be conveyed pursuant to the Transaction Documents) its chief executive

The Borrower will cause each of the Collection Accounts that is currently in the name of an Originator to be transferred to it and into its own name within a reasonable period of time after the initial Advance hereunder.

(iii)Upon demand of any of the Agents at any time following the occurrence of any Unmatured Default or Event of Default, the Borrower or the Servicer shall establish a segregated account at Wachovia Bank, National Association which is subject to a perfected security interest in favor of the Administrative Agent, for the benefit of the Secured Parties (the“Collateral Account”), into which all deposits from time to time in the Collection Accounts, and all other Collections, are concentrated pending application in accordance with the terms of this Agreement to the Obligations.

(j)Further Assurances.

(g)Restricted Payments by the Borrower. The Borrower will not:

(i)Purchase or redeem any shares of the capital stock of the Borrower, declare or pay any dividends thereon (other than stock dividends), make any distribution to stockholders or set aside any funds for any such purpose, unless, in each of the foregoing cases: (A) such purchase, redemption, payment or distribution is made on, or immediately following, a Settlement Date after payment of all Obligations due and owing on such Settlement Date, and (B) after giving effect to such purchase, redemption, payment or distribution, the Borrower’s net worth (determined in accordance with GAAP) will at all times be at least 10% of the greater of the Aggregate Commitment or the aggregate outstanding principal amount of the Advances; or

(l)Disposition of Receivables and Related Assets. Except pursuant to this Agreement, the Borrower will not sell, lease, transfer, assign, pledge or otherwise dispose of or encumber (in one transaction or in a series of transactions) any Receivables and Related Assets.

(m)Borrowing Base. The Borrower will not request any Advance if, after giving effect thereto, the aggregate outstanding principal balance of the Loans would exceed the Borrowing Base.

Section 7.4 Separate Existence of the Borrower. Each Loan Party hereby acknowledges that Lenders and the Agents are entering into the transactions contemplated hereby in reliance upon the Borrower’s identity as a legal entity separate from the Servicer and its other Affiliates. Therefore, each Loan Party shall take all steps specifically required by this Agreement or reasonably required by any of the Agents to continue the Borrower’s identity as a separate legal entity and to make it apparent to third Persons that the Borrower is an entity with assets and liabilities distinct from those of its Affiliates, and is not a division of Quest Diagnostics or any other Person. Without limiting the foregoing, each Loan Party will take such actions as shall be required in order that:

(a)The Borrower will be a limited purpose corporation whose primary activities are restricted in its Certificate of Incorporation to purchasing or otherwise acquiring from the Originators and owning, holding, granting security interests in the Collateral, entering into agreements for the financing and servicing of the Receivables, and conducting such other activities as it deems necessary or appropriate to carry out its primary activities;

(b)Not less than one member of the Borrower’s Board of Directors (the“Independent Director”) shall be an individual who is not, and never has been, a direct, indirect or beneficial stockholder, officer, director, employee, affiliate, associate, material supplier or material customer of Quest Diagnostics or any of its Affiliates (other than an Affiliate organized with a limited purpose charter for the purpose of acquiring receivables or other financial assets or intangible property). The certificate of incorporation of the Borrower shall provide that (i) at least one member of the Borrower’s Board of Directors shall be an Independent Director, (ii) the Borrower’s Board of Directors shall not approve, or take any other action to cause the filing of, a voluntary bankruptcy petition with respect to the Borrower unless the Independent Director shall approve the taking of such action in writing prior to the taking of such action and (iii) the provisions requiring an independent director and the provision described in clauses (i) and (ii) of this paragraph (b) cannot be amended without the prior written consent of the Independent Director;

(c)The Independent Director shall not at any time serve as a trustee in bankruptcy for the Borrower or any Affiliate thereof;

(d)Any director, employee, consultant or agent of the Borrower will be compensated from the Borrower’s funds for services provided to the Borrower. The Borrower will not engage any agents (other than its attorneys, auditors and other professionals) and will not engage any Person other than the Servicer to deal with the Collateral as contemplated by the Transaction Documents;

(e)The Borrower will contract with the Servicer to perform for the Borrower all operations required on a daily basis to service the Collateral.

ADMINISTRATION AND COLLECTION

Section 8.1 Designation of Servicer.

(a)Quest Diagnostics as Initial Servicer. The servicing, administering and collection of the Receivables shall be conducted by the Person designated as Servicer hereunder from time to time in accordance with this Section 8.1. Until both of the Co-Agents give to Quest Diagnostics a Successor Notice (as defined in Section 8.1(b)), Quest Diagnostics is hereby designated as, and hereby agrees to perform the duties and obligations of, Servicer pursuant to the terms hereof.

(b)Successor Notice; Servicer Transfer Events. Upon Quest Diagnostics’ receipt of a notice from both of the Co-Agents following a Servicer Transfer Event of the designation of a new Servicer (a “Successor Notice”), Quest Diagnostics agrees that it will terminate its activities as Servicer hereunder in a manner that will facilitate the transition of the performance of such activities to the new Servicer, and, after agreeing in writing to be bound by the terms of this Agreement (including, without limitation, the provisions of Section 14.14), the Co-Agents’ designee shall assume each and all of Quest Diagnostics’ obligations to service and administer such Receivables, on the terms and subject to the conditions herein set forth, and Quest Diagnostics shall use its reasonable best efforts to assist the Co-Agents’ designee in assuming such obligations. Without limiting the foregoing, Quest Diagnostics agrees, at its expense, to take all actions necessary to provide the new Servicer with access to all computer software necessary to generate reports useful in collecting or billing Receivables, solely for use in collecting and billing Receivables. If Quest Diagnostics disputes the occurrence of a Servicer Transfer Event, Quest Diagnostics may take appropriate action to resolve such dispute;provided that Quest Diagnostics must terminate its activities hereunder as Servicer and allow the newly designated Servicer to perform such activities on the date specified by the Co-Agents as described above, notwithstanding the commencement or continuation of any proceeding to resolve the aforementioned dispute, if both of the Co-Agents reasonably determines, in good faith, that such termination is necessary or advisable to protect the Secured Parties’ interests hereunder.

(c)Subcontracts. So long as Quest Diagnostics (or any of its existing or hereafter arising Affiliates approved by the Co-Agents at the request of Quest Diagnostics or the Borrower subject to satisfaction of the Rating Agency Condition) is acting as the Servicer, it may subcontract with any other Originator or other direct or indirect Subsidiary of Quest Diagnostics, for servicing, administering or collecting all or any portion of the Receivables,provided, however, that no such subcontract shall relieve Quest Diagnostics (or such approved affiliated substitute Servicer, if such approval is not conditioned upon Quest Diagnostics’ issuance of a performance guaranty with respect to such affiliated substitute Servicer) of its primary liability for performance of its duties as Servicer pursuant to the terms hereof and any such sub-servicing arrangement may be terminated at the request of any of the Agents at any time after a Successor Notice has been given. In addition to the foregoing, with the prior written consent of the Co-Agents (which consent shall not be unreasonably withheld or delayed), any Servicer may subcontract with other Persons for servicing, administering or collecting all or any portion of the Receivables,provided, however, that no such subcontract shall relieve such Servicer of its

primary liability for performance of its duties as Servicer pursuant to the terms hereof and any such sub-servicing arrangement may be terminated at the request of any of the Agents at any time that the Co-Agents reasonably determine that such sub-servicer is not performing adequately.

(d)Expense Indemnity after a Servicer Transfer Event. In addition to, and not in lieu of the Servicer’s Fee, if Quest Diagnostics or one of its Affiliates is replaced as Servicer following a Servicer Transfer Event, the Borrower shall reimburse the Servicer within 10 Business Days after receipt of a written invoice, any and all reasonable costs and expenses of the Servicer incurred in connection with its servicing of the Receivables for the benefit of the Secured Parties.

(E) unless the Borrower has actual knowledge that the Administrative Agent has prepared a financing statement, amendment or similar instrument or document under the UCC of any applicable jurisdiction or other applicable laws with respect to any Collateral, the failure to deliver to the Administrative Agent on a timely basis any such financing statement, amendment or similar instrument or document or to authorize its filing on a timely basis;

(F) any dispute, claim, offset or defense (other than discharge in bankruptcy) of the Obligor to the payment of any Receivable (including, without limitation, a defense based on such Receivables or the related Contract and/or Invoice not being a legal, valid and binding obligation of such Obligor enforceable against it in accordance with its terms), or any other claim resulting from the sale of the services related to such Receivable or the furnishing or failure to furnish such services;

(O) the occurrence of any Event of Default of the type described in Section 10.1(e);

(P) any loss incurred by any of the Secured Parties as a result of the inclusion in the Borrowing Base of Receivables owing from any single Obligor and its Affiliated Obligors which causes the aggregate Unpaid Net Balance of all such Receivables to exceed the applicable Obligor Concentration Limit; or

For purposes of this Agreement, an Indemnified Party shall be deemed to have “actually realized” tax consequences to the extent that, and at such time as, the amount of Taxes payable (including Taxes payable on an estimated basis) by such Indemnified Party is increased above or reduced below, as the case may be, the amount of Taxes that such Indemnified Party would be required to pay but for receipt or accrual of the indemnity payment or the incurrence or payment of such indemnified amount, as the case may be.

(c)Contribution. If for any reason the indemnification provided above in this Section 13.1 (and subject to the exceptions set forth therein) is unavailable to an Indemnified Party or is insufficient to hold an Indemnified Party harmless, then the Borrower shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by such Indemnified Party on the one hand and the Borrower on the other hand but also the relative fault of such Indemnified Party as well as any other relevant equitable considerations.

Section 13.2 Indemnities by Servicer. Without limiting any other rights which any Indemnified Party may have hereunder or under applicable law, the Servicer hereby agrees to indemnify each of the Indemnified Parties forthwith on demand, from and against any and all Indemnified Amounts awarded against or incurred by any of them arising out of or relating to the Servicer’s performance of, or failure to perform, any of its obligations under or in connection with any Transaction Document, or any representation or warranty made by the Servicer (or any of its officers) under or in connection with any Transaction Document, any Monthly Report, Weekly Report, computation of Cash Collateral Payment or any other information or report delivered by or on behalf of the Servicer, which shall have been false, incorrect or misleading in any material respect when made or deemed made or delivered, as the case may be, or the failure of the Servicer to comply with any applicable law, rule or regulation with respect to any Receivable or the related Contract and Invoice. Notwithstanding the foregoing, in no event shall any Indemnified Party be awarded any Indemnified Amounts (a) to the extent determined by a court of competent jurisdiction to have resulted from gross negligence or willful misconduct on the part of such Indemnified Party or (b) as recourse for Indemnified Amounts to the extent the same includes losses in respect of Receivables which are uncollectible on account of the insolvency, bankruptcy or lack of creditworthiness of the related Obligor.

If for any reason the indemnification provided above in this Section 13.2 (and subject to the exceptions set forth therein) is unavailable to an Indemnified Party or is insufficient to hold an Indemnified Party harmless, then the Servicer shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by such Indemnified Party on the one hand and the Servicer on the other hand but also the relative fault of such Indemnified Party as well as any other relevant equitable considerations.

Section 14.14 Business Associate Agreement; Health Care Data Privacy and SecurityRequirements.

(a)Definitions.“HIPAA”means the Health Insurance Portability and Accountability Act of 1996. The terms “EDI Rule,” “Privacy Regulations” and“Security Regulations” refer to all of the rules and regulations in effect from time to time issued pursuant to HIPAA and applicable to (respectively) the electronic data interchange, privacy and security of Individually Identifiable Health Information (found at Title 45, Code of Federal Regulations (CFR) Parts 160, 162, and 164).“Business Associate” refers to each of the Agents, the Borrower and any successor Servicer to Quest Diagnostics appointed by the Agents pursuant to this Agreement, severally and not jointly. All other terms used, but not otherwise defined in this Section, shall have the same meaning as those terms defined in the Title 45 of the Code of Federal Regulations applicable to HIPAA or any successor statute.

(b)Privacy. In accordance with the purposes of this Agreement, Quest Diagnostics will disclose to each Business Associate, and each Business Associate will use,

disclose, and/or create Protected Health Information (hereinafter called“PHI”)only on behalf of Quest Diagnostics for the specific purposes set forth in this Agreement. Each Business Associate agrees not to use or further disclose any PHI or Individually Identifiable Health Information received from Quest Diagnostics or created by any Business Associate other than as permitted by this Agreement or as required by applicable law or regulations, including the Privacy Regulations and the Security Regulations. Each Business Associate will only use or disclose the Minimum Necessary PHI to accomplish the intended purpose of its uses or disclosures. Each Business Associate will implement appropriate safeguards to prevent the use or disclosure of an Individual’s PHI other than as provided for by this Agreement or in accordance with law and shall document its safeguards. Each Business Associate will provide access to an Individual’s PHI upon the reasonable request of Quest Diagnostics, will make any amendments to an Individual’s PHI as directed by Quest Diagnostics, and will maintain a record of disclosures of PHI as required for Quest Diagnostics to make an accounting to the Individual as required by the Privacy Regulations. Each Business Associate will promptly report to Quest Diagnostics any use or disclosure of an Individual’s PHI not provided for by this Agreement or any security incident (as that term is defined in the Security Regulations) of which such Business Associate becomes aware. In the event any Business Associate contracts with any subcontractors or agents and provides them with an Individual’s PHI, such Business Associate shall include provisions in its agreements whereby the sub-contractor or agent agrees to the same privacy and security requirements and restrictions and conditions that apply to such Business Associate with respect to the Individual’s PHI. Each Business Associate will, upon reasonable notice, make its internal practices, books, and records relating to the use and disclosure of an Individual’s PHI available to the Secretary of Health and Human Services and to Quest Diagnostics to the extent required for determining compliance with this Section, the Privacy Regulations, and the Security Regulations. Notwithstanding the foregoing, no legal privilege shall be deemed waived by any Business Associate or Quest Diagnostics by virtue of this clause (b) of this Section. Quest Diagnostics may terminate this Agreement without penalty or recourse if it determines that any Business Associate has violated a material term of this Section or applicable law that is not cured within thirty (30) calendar days after delivery of the notice of violation to all of the Business Associates or, in lieu of termination, Quest Diagnostics, in its sole discretion, may report the breach to the Secretary. Upon termination of this Agreement for any reason, each Business Associate and its sub-contractors or agents agree to return or to destroy all PHI and retain no copies (and to certify to such actions) unless otherwise agreed by Quest Diagnostics or such return or disclosure is not reasonably feasible (in which case, at no additional cost to Quest Diagnostics, each Business Associate will extend the protections of this Section to the PHI that such Business Associate maintains and limit any further uses and disclosures of the PHI to the purposes that make the return or destruction of the PHI not feasible).

(c)Security. Each Business Associate shall adopt, implement and maintain throughout the term of this Agreement security policies, procedures, and practices, administrative, physical and technical safeguards, and security mechanisms that reasonably and adequately protect the confidentiality, integrity, and availability of the PHI that it creates, receives, maintains, or transmits on behalf of Quest Diagnostics (“Business Associate Safeguards”), and each Business Associate shall require its sub-contractors or agents to adopt Business Associate Safeguards that are equally appropriate and adequate. Quest Diagnostics

may terminate this Agreement at any time, without penalty, if it determines, in its sole discretion, that the Business Associate Safeguards are unsatisfactory.

(d)EDI. If Business Associate conducts all or any portion of its business or pays any claim in a transaction covered by the Electronic Data Interchange (“EDI”) Rule on behalf of Quest Diagnostics, then Business Associate covenants and warrants that it shall and shall require its agents and/or subcontractors to comply with the requirements of the EDI Rule that are applicable to Quest Diagnostics.

(e)Benefit. This Section is not intended to create any right in or obligations to any Person that is not a party to this Agreement, including Individuals.

(f)Mitigation. In addition to any rights of indemnification contained in this Agreement, each Business Associate will take commercially reasonable steps to mitigate any harm caused by its breach of this Section and/or reimburse Quest Diagnostics for the cost of commercially reasonable mitigation based upon, arising out of or attributable to the acts or omissions of such Business Associate, its employees, officers, directors, agents, or subcontractors for uses or disclosures in violation of this Section.

(g)Amendment. Each of the Business Associates and Quest Diagnostics agree to amend this Section in such manner as is reasonably necessary to comply with any amendment of (i) HIPAA or other applicable law, (ii) the Privacy Regulations, the Security Regulations, or other applicable regulations, or (iii) any applicable court decision or binding governmental policy. If the parties are unable to agree on an amendment within 30 days of notice from Quest Diagnostics to each Business Associate of the requirement to amend this Section, Quest Diagnostics may, at its option, terminate this Agreement upon written notice to the Business Associates.

(h)Survival. This Section and the confidentiality, privacy, security, and other requirements established herein shall survive termination of this Agreement.

(i)Interpretation. Any ambiguity in this Section shall be resolved in favor of a meaning that permits Quest Diagnostics to comply with the Privacy Regulations, the Security Regulations and the EDI Rule.

(j)Several Liability of Business Associates. No Business Associate shall have any liability to Quest Diagnostics or any third party of any kind or nature, whether such liability is asserted on the basis of contract, tort (including negligence or strict liability), or otherwise, arising from the failure of any other Business Associate to fulfill its obligations under this Section.

Section 14.15 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall constitute one and the same Agreement.

Section 14.16 No Recourse Against Other Parties. The several obligations of the Lenders under this Agreement are solely the corporate obligations of such Lender. No recourse

shall be had for the payment of any amount owing by such Lender under this Agreement or for the payment by such Lender of any fee in respect hereof or any other obligation or claim of or against such Lender arising out of or based upon this Agreement, against any employee, officer, director, incorporator or stockholder of such Lender. Each of the Borrower, the Servicer and the Administrative Agent agrees that each of the Conduits shall be liable for any claims that such party may have against such Conduit only to the extent that such Conduit has excess funds and to the extent such assets are insufficient to satisfy the obligations of such Conduit hereunder, such Conduit shall have no liability with respect to any amount of such obligations remaining unpaid and such unpaid amount shall not constitute a claim against such Conduit. Any and all claims against either of the Conduits or any of the Agents shall be subordinate to the claims against such Persons of the holders of such Conduit’s Commercial Paper Notes and its Liquidity Banks.
